Problems solved by technology

[0003] In the production process of the stretch film blown film process, it needs to be blown and then cooled and rolled. When cooling, the existing water-cooled type is used, but when water-cooled, the cooling water utilization rate in the water-cooled pool is low, which not only causes energy waste. and lower overall cooling efficiency

Embodiment 1

[0020] An adjustable water cooling pool for stretch film blow molding processing, comprising a water cooling pool 1, two rotatable water cooling rolls 11 are arranged in the water cooling pool 1, and the upper end of the water cooling pool 1 on one side of the water cooling roll 11 is provided with There is a discharge roller 12, and the two ends of the discharge roller 12 are fixed on the upper end of the water cooling pool 1 by fixing rods 19.

[0021] An adsorption roller 17 is arranged between the discharge roller 12 and the water-cooled roller 11, and there are two adsorption rollers 17, and the adsorption rollers 17 are close to each other but not in contact.

[0022] Utilizing the adsorption roller 17, the moisture on the surface of the stretched film 2 after water cooling can be effectively adsorbed, and the post-drying efficiency of the stretched film 2 is improved.

[0023] The two ends of the discharge roller 12 are movably connected with the fixed rod 19 through th...

Embodiment 2

[0026] The same as embodiment 1 is no longer repeated, and the difference with embodiment 1 is:

[0027] see Figure 1-2 , between the discharge roller 12 and the water-cooled roller 11, symmetrically distributed wiper blades 15 are arranged. Both ends of 15 are provided with symmetrically distributed first positioning plates 14 , and the bottom of the first positioning plates 14 is fixedly connected with the upper end of the water cooling pool 1 .

[0028] The design of the wiper 15 enables the large amount of moisture on the surface of the stretched film 2 to be quickly separated from the surface of the film after water cooling, thereby improving the overall drying efficiency.

[0029] The two ends of the wiper blade 15 on one side are provided with symmetrically distributed connecting shafts 151, and the connecting shafts 151 are connected to the first positioning plate 14 through a torsion spring (not shown in the figure). The wiper blade 15 is fixedly connected with the...

Embodiment 3

[0033] The same as embodiment 1 is no longer repeated, and the difference with embodiment 1 is:

[0034] see Figure 3-4 , both ends of the water-cooled roller 11 are provided with symmetrically distributed adjusting shafts 111, and the inner wall of the water-cooled pool 1 is provided with symmetrically distributed adjusting grooves 13 that match the adjusting shafts 111, and the adjusting grooves 13 are provided with reset Spring 134, one end of the return spring 134 is connected to the bottom of the adjustment groove 13, and the other end of the return spring 134 is connected to the adjustment shaft 111, and the middle part of the upper end of the water-cooled roller 11 is provided with a pressure block 131 that matches the size of the water-cooled roller 11. The upper end of the pressing block 131 is provided with a hydraulic rod 132 that can move up and down.

[0035] The design of the adjustment groove 13 and the hydraulic rod 132 enables the stretched film 2 to move do...

Abstract

The invention belongs to the technical field of winding film processing, and particularly relates to an adjustable water cooling tank for winding film blow molding processing. The adjustable water cooling tank comprises a water cooling tank body, wherein two rotatable water cooling rollers are arranged in the water cooling tank body; a discharging roller is arranged at the position, positioned onone side of the water cooling rollers, of the upper end of the water cooling tank body; the two ends of the discharging roller are fixed to the upper end of the water cooling tank body through fixingrods; adjusting shafts which are symmetrically distributed are arranged at the two ends of the water cooling rollers; adjusting grooves which are symmetrically distributed and matched with the adjusting shafts are formed in the inner wall of the water cooling tank body; return springs are arranged in the adjusting grooves; one of the ends of the return springs is connected with the bottoms of theadjusting grooves, and the other one of the ends of the return springs is connected with the adjusting shafts; pressing blocks matched with the water cooling rollers in size are arranged in the middles of the upper ends of the water cooling rollers; and hydraulic rods capable of moving up and down are arranged at the upper ends of the pressing blocks. Up-down adjustment of the water cooling rollers is achieved, cooling can be carried out at different heights in the water cooling tank body according to needs, and convenience and rapidness are achieved.

Description

technical field [0001] The invention belongs to the technical field of stretch film processing, and in particular relates to an adjustable water cooling pool for stretch film blow molding processing. Background technique [0002] Stretch film is processed by extrusion process, and its main raw materials are polyvinyl chloride, low-density polyethylene, ethylene-vinyl acetate copolymer, linear low-density polyethylene, polybutadiene and other viscoelastic high polymers. LLDPE, LDPE, etc. are used, mainly composite films. It is produced by casting process or blow molding process. The main equipment is extruder and corresponding auxiliary equipment, such as batching, mixing, feeding system, thickness measuring system and coiling system. [0003] In the production process of the stretch film blown film process, it needs to be blown and then cooled and rolled. When cooling, the existing water-cooled type is used, but when water-cooled, the cooling water utilization rate in the w...
