The high-friction coefficient parts include an elastic material. Outer peripheries of the high-friction coefficient parts are inclined with respect to an axial direction of the core bar. The cleaning member is roller-shaped and is configured to clean a surface of a roller member to be cleaned in contact therewith. A charging device and a process cartridge also include the cleaning member.

The invention discloses a thermal processing, sterilizing and dewatering device of a solid wood panel. The thermal processing, sterilizing and dewatering device comprises a support and a conveying belt matched with the support, wherein a plurality of drying cavities which are arranged side by side and are communicated with one another are fixed above the conveying belt; upper and lower rows of parallel magnetic control pipes are fixed on the inner wall of each drying cavity; U-shaped grooves are fixedly formed in two sides of the conveying belt; two air cylinders are fixedly arranged in the support; the output ends of the two air cylinders are arranged in the U-shaped grooves in a sliding mode; the inner walls at two sides of each drying cavity are also provided with bulges which are in contact with the upper surfaces of two end parts of the conveying belt. The two air cylinders are fixed in the support, and the two ends of the conveying belt are provided with the U-shaped grooves; the output ends of the air cylinders are arranged in the U-shaped grooves in the sliding mode, so that the two air cylinder perform shrinkage stretching at opposite directions respectively, and the conveying belt can swing left and right; the contact frequency of the outer wall, in per unit of area, of a log with microwaves is increased; the drying effect of the log is improved.

The present invention relates to the technical field of ironing devices for textile T-shirt processing, in particular to an ironing device for textile T-shirt processing. An integrally formed upper support cylinder is arranged on the upper side of the U-shaped center plate. The improvement of the T-shirt auxiliary device can greatly increase the usability of the T-shirt, which is conducive to ironing T-shirts of different sizes, and can effectively avoid the problem of marks on the T-shirt after ironing, thereby ensuring T-shirt The quality of the T-shirt after ironing; the invention operates with the U-shaped center rod as the center, which allows the staff to quickly and appropriately adjust the size of the auxiliary device, thus effectively solving the problem of the staff laying the T-shirt flat, At the same time, the operation of the auxiliary device can save the staff time and effort.

The invention discloses a synchronous ejector pin mechanism of an injection mold. The synchronous ejector pin mechanism of the injection mold comprises a fixed mold and a movable mold which are arranged left and right, a female mold cavity with an opening in the right side is formed in the fixed mold, a male mold block protruding leftwards is formed on the movable mold, and a plastic product is formed in a cavity formed by the male mold block and the female mold cavity; a driving cavity and a plurality of ejector pin holes for communicating the driving cavity with the female die cavity are formed in the fixed die; and a plurality of ejector pin mechanisms and a driving mechanism for driving the ejector pin mechanisms to work simultaneously are arranged in the driving cavity. Multiple ejector pins are driven by the same driving mechanism to synchronously move, so that the ejector pins are uniformly stressed on the plastic product, and the plastic product is effectively prevented from generating marks or being damaged.

The invention discloses a mold opening impression prevention novel injection mold for plastic product production. The mold opening impression prevention novel injection mold for plastic product production structurally comprises a demolding assisting device, a base, a lower mold, an upper mold, an air flow main channel, limiting blocks and air flow branch channels. The four corners of the bottom surface of the upper mold are matched with locating holes at the four corners of the top surface of the lower mold through locating columns correspondingly. Compared with the prior art, the mold openingimpression prevention novel injection mold for plastic product production has the beneficial effects that air is compressed through the polarity repulsion and attraction principle; the area of the air flow channels is limited, air flow is concentrated and acts on a movable disk to expand the area of the air flow main channel, channel openings of air flow branch channel opening appearance and disappearance startup groups, and the air flow is guided out from the channel openings of the air flow branch channels to act on plastic products. Cooling on the plastic products is accelerated. Moreover,the plastic products can be ejected by the air flow to be subjected to rapid demolding. An ejector rod ejection method is abandoned. The plastic products are efficiency protected against impression.The attractiveness of the plastic products can be ensured. Manufacturing resources are saved. The manufacturing cost is lowered.

The invention provides bumper strip manufacturing equipment. The bumper strip manufacturing equipment comprises an extruder, a salt bath device, a washing device, a blow-drying device and a drying device, wherein the washing device comprises a washing bin, a first conveying roller line and a plurality of rotary washing mechanisms, wherein the first conveying roller line penetrates through the washing bin; the first conveying roller line comprises a plurality of first conveying roller shafts which are arranged at intervals; each rotary washing mechanism comprises a motor and a rotating shaft pipe; one end of each rotating shaft pipe communicates with a high-pressure water source; the other end of each rotating shaft pipe communicates with a water spraying line after penetrating through thewashing bin; the length of each water spraying line is larger than the width of a bumper strip; and after rotating in the length direction of the first conveying roller line, the water spraying linesof the rotary washing mechanisms are straightly engaged in the length direction of the first conveying roller line. According to the bumper strip manufacturing equipment provided by the invention, thewater spray range of each rotary washing mechanism is relatively large, so the bumper strip can be washed and cleaned effectively; and by adopting the conveying roller line, the friction between thebumper strip and the conveying roller shafts can be reduced.

The invention relates to a horizontal electroless nickel / immersion gold assembly line and an electroless nickel / immersion gold method. The horizontal electroless nickel / immersion gold assembly line comprises an automatic plate placing machine, a first micro-etching bath, a first rinsing bath set, a sand blasting machine, a second rinsing bath set, an oil removing bath set, a third rinsing bath set, a second micro-etching bath, a fourth rinsing bath set, a pre-soaking bath, an activated bath set, a fifth rinsing bath set, a pickling bath, a sixth rinsing bath set, a first surface treatment system, a seventh rinsing bath set, a second surface treatment system, a gold recovery bath, an eighth rinsing bath set, an operation station, a ninth rinsing bath set, a blowing-drying bath set, an automatic plate collecting machine and a conveying mechanism which are sequentially arranged.
