A shaping device for producing POF heat shrink film

Abstract

This utility model discloses a shaping device for POF heat shrink film production, including a drying chamber. Feed guide plates are provided at both the front and rear of the drying chamber, and a reduction motor is located near the center of the side end face of the feed guide plate. By setting up the guiding device, during the drying and shaping of the shrink film, the reduction motor can be limited by the sliding of the cam slide groove and the guide slide shaft, thereby cyclically driving the support slide to move back and forth. Simultaneously, the transmission gear can drive five sets of guide gears to mesh synchronously during the back-and-forth movement via the transmission rack. This allows the five sets of guide gears to drive the drying nozzles to rotate at high speed, enabling the five sets of drying nozzles to perform a comprehensive and uniform drying operation on the outside of the shrink film during the back-and-forth movement. This improves both the power utilization efficiency and the drying efficiency of the shrink film.

Description

Technical Field

[0001] This utility model relates to the technical field of POF heat shrink film processing equipment, specifically a shaping device for POF heat shrink film production. Background Technology

[0002] Drying and setting POF heat shrink film is a core step to ensure its stable performance, uniform shrinkage, and reliable heat sealing. Drying and setting can precisely control the longitudinal and transverse shrinkage rates of the film, avoid packaging wrinkles or gaps caused by uneven shrinkage, and improve the stability of the shrink film in subsequent use.

[0003] For example, CN215283350U discloses a heat shrink film production shaping device for blowing heat shrink film. It includes a box, a support, a disc, fan blades, a connecting rod assembly, and a first driving component. The box is hollow inside. The support is built into the box and positioned above the heat shrink film. The disc is rotatably connected to the support around its own axis. The fan blades are rotatably connected to the support and positioned relative to the heat shrink film. The connecting rod assembly includes a fixed rod and a rocker arm. The fixed rod is connected to the inner top wall of the box. One end of the rocker arm is hinged to the fixed rod, and the other end is rotatably connected to the disc, with the rotatable connection point offset from the center of the disc. The first driving component has a fixed end and an output end. The fixed end of the first driving component is hinged to the inner top wall of the box, and the output end is connected to the fan blades and the disc, driving the fan blades and the disc to rotate around their own axes, and via the disc, fixed rod, and rocker arm, driving the support and fan blades to swing. This invention solves the problems of poor shaping effect and long time consumption in existing technologies.

[0004] Although the above-mentioned equipment can perform drying and positioning operations on heat shrink film, the uniformity of drying the heat shrink film is still insufficient, which reduces the stability of subsequent positioning of the heat shrink film. Therefore, there is an urgent need for a shaping device for POF heat shrink film production to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a shaping device for the production of POF heat shrink film, so as to solve the problems mentioned in the background art.

[0011] Preferably, the side of the transmission gear is meshed with the transmission rack, and the five sets of guide gears are meshed with each other, which can effectively improve the stability of the equipment's transmission and also improve the equipment's power utilization efficiency.

[0012] Preferably, the support slide is adapted to the cam slide groove through the guide slide shaft and thus slidably engaged with the inner end face of the drying chamber. When drying the shrink film, the cam slide groove can be limited by sliding with the guide slide shaft, thereby driving the support slide to move back and forth, effectively improving the uniformity and efficiency of subsequent drying of the shrink film.

[0013] Preferably, the drying nozzle is adapted to the sealing rotating cylinder and the sealing rotating groove and is rotatably engaged with the inner end face of the support slide.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model, by setting a guiding device, allows the reduction motor to drive the support slide to move back and forth cyclically through the sliding limit of the cam slide groove and the guide slide shaft during the drying and shaping of the shrink film. At the same time, the transmission gear can drive the five sets of guide gears to mesh synchronously through the transmission rack during the back and forth movement, so that the five sets of guide gears can drive the drying nozzles to rotate at high speed. Thus, the five sets of drying nozzles can perform a comprehensive and uniform drying operation on the outside of the shrink film through high-speed rotation during the back and forth movement, which not only improves the power utilization efficiency of the equipment, but also improves the drying efficiency of the shrink film.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides an embodiment of a shaping device for producing POF heat shrink film, comprising a drying chamber 8, with feeding guide plates 4 at both the front and rear of the drying chamber 8, a reduction motor 1 located near the middle of the side end face of the feeding guide plate 4, a straight groove 7 formed near the bottom of the side end face of the drying chamber 8, and a transmission rack 3 provided on the inner end face of the drying chamber 8 away from the side wall of the straight groove 7.

[0023] The transmission shaft 6 is fixedly installed at the output end of the geared motor 1, and a cam groove 5 is provided on the inner end face of the transmission shaft 6. The cam groove 5 is used for cyclic guidance.

[0024] The guide device 2 is cyclically slidably connected to the inner end face of the drying chamber 8 via the cam slide groove 5.

[0025] like Figure 3 The guide device 2 includes a support slide 26. A limiting slip ring 27 is fixedly installed at the center of the upper end face of the support slide 26, and a guide slide shaft 28 is installed at the bottom of the inner end face of the limiting slip ring 27. Five sets of drying devices 22 are equidistantly rotatably connected to the inner end face of the support slide 26. A sealing groove 24 is opened at the position of the inner end face of the support slide 26 opposite to the drying device 22. Air guide grooves 23 are equidistantly opened on the inner end face of the sealing groove 24. A transmission gear 25 is installed on the upper end face of the drying device 22 located at the sidemost end. A docking guide tube 21 is installed at the center of the side end face of the support slide 26.

[0026] like Figure 4 The drying device 22 includes a guide gear 223, a sealing cylinder 222 is provided at the center of the lower end face of the guide gear 223, and four sets of air inlet guide grooves 221 are equidistantly provided on the side end face of the sealing cylinder 222. A drying nozzle 224 is provided at the center of the lower end face of the sealing cylinder 222.

[0027] like Figure 2 The side of the transmission gear 25 meshes with the transmission rack 3, and the five sets of guide gears 223 mesh with each other, which can effectively improve the stability of the equipment's transmission and also improve the equipment's power utilization efficiency.

[0028] like Figure 1 and Figure 2 The support slide 26 is adapted to the guide slide shaft 28 and the cam slide groove 5 and thus slidably engaged on the inner end face of the drying chamber 8. When drying the shrink film, the cam slide groove 5 can be limited by sliding with the guide slide shaft 28, thereby driving the support slide 26 to move back and forth, which effectively improves the uniformity and efficiency of subsequent drying of the shrink film.

[0029] like Figure 2 and Figure 3 The drying nozzle 224 is adapted to the sealing groove 24 through the sealing rotating cylinder 222 and is rotatably locked onto the inner end face of the support slide 26. The air inlet guide groove 221 and the air guide groove 23 are directly opposite each other. During the drying operation, the sealing rotating cylinder 222 can be rotated and limited inside the sealing groove 24. At the same time, the air guide groove 23 and the sealing groove 24 are connected and directly opposite each other, which can improve the subsequent conduction efficiency of drying gas.

[0030] Working Principle: Before use, the operator can position the shrink film feeding module at the front of the drying chamber 8. The shrink film to be dried can pass through the two sets of feeding guide plates 4 for easy subsequent drying. At the same time, the operator can connect the external drying gas duct to the docking duct 21 to facilitate the supply of drying gas. During the drying operation, the operator can intermittently guide the shrink film to be dried into the drying chamber 8, and then start the reduction motor 1. At this time, the reduction motor 1 can drive the transmission shaft 6 to rotate. Simultaneously, the cam slide groove 5 can be limited by sliding with the guide slide shaft 28, thereby reciprocating the movement of the limiting mechanism. The slip ring 27 and the support slide 26 are displaced inside the drying chamber 8. When the support slide 26 is displaced, the transmission gear 25 can be limited by the transmission rack 3, thereby driving the guide gear 223 to rotate. Since the five sets of guide gears 223 mesh with each other, the five sets of guide gears 223 can drive the five sets of drying nozzles 224 to rotate at high speed while the support slide 26 moves back and forth. At the same time, the external drying gas can be introduced into the air inlet guide groove 221 through the support slide 26 and the air guide groove 23, and then the shrink film is dried evenly through the drying nozzles 224, thereby improving the drying efficiency of the shrink film.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
