Embodiment

[0046] Embodiment: a kind of injection hook production equipment, such as figure 1 As shown, a drying tower 7 is included, and a discharge port is arranged below the drying tower 7. The discharge port communicates with the screw extruder 8, and the outside of the screw extruder 8 sets of barrels is wound with a group of heating coils. According to the thermocouple The temperature information fed back can control the heating temperature of each section of the sleeve. The screw extruder 8 is sequentially connected with a melt filter device 1 , a metering pump 9 , a die head 10 , a pressurizing part 11 , a guide roller 121 , a pulling roller 122 and a winding roller 13 . Wherein, the pressing part 11 includes a pressing roller 111, a mold roller 112, a peeling roller 113, and a pressing roller 114, and the four contact in sequence, and several holes arranged in the same direction and having the same shape as the injection hook are evenly provided on the mold roller 112. The die ...

Abstract

The invention discloses injection hook production equipment, a melt filtering device thereof and a manufacturing method for an injection hook. The melt filtering device is provided with a filtering cavity allowing materials to pass through. The melt filtering device is further provided with moving shafts capable of making axial movement. The moving shafts and the filtering cavity are arranged in a penetrating mode. Detachable filtering nets are arranged at the connecting positions of the moving shafts and the filtering cavity. One end of each moving shaft is provided with a hydraulic device used for pushing the corresponding moving shaft, and the other end of each moving shaft is connected with an air exhausting device used for resetting the filtering cavity. The melt filtering device has the advantages that foreign matter such as impurities and dust in melt (like polylactic acid melt used for preparing the injection hook) can be filtered out, the phenomenon that the foreign matter blocks subsequent operation equipment can be prevented, and thus the melt can execute subsequent operation smoothly; and moreover the quality of finished products made of the melt is improved.

Description

technical field [0001] The invention relates to the technical field of injection hook production, in particular to an injection hook production equipment, a melt filtering device thereof and a manufacturing method of the injection hook. Background technique [0002] Hook and fastening tape, because of its easy felting and separation characteristics, is widely used in applications that require two separate parts to be releasably bonded, such as in garments, shoe materials, personal hygiene products applications in related fields. Velcro is generally used in pairs, and is divided into two joint surfaces of hook and wool. The hook surface can also be used alone, and can be glued to non-woven fabrics or raised fabrics. Compared with the traditional hook and loop fasteners, the hook-and-loop fasteners of the injection hook type are thinner, have stronger lateral tension and peeling tension, and are not easy to lose the appearance of the finished product due to negligence in the ...
