Description

Technical Field

[0001] This utility model relates to the technical field of coating curtain type adhesive coating device, specifically an adhesive coating edge trimmer. Background Technology

[0002] Self-adhesive labels are a common household item, available in single-layer, double-layer, and various industry-specific versions. Each label requires an adhesive layer to be applied to a backing paper. Typically, this adhesive layer is formed by spraying a water curtain from a curtain-type adhesive coating device onto the backing paper. Current adhesive coating edge adjusters are symmetrically arranged in two sets. Adjusting the elastic tabs on both sets requires turning or pushing two adjusting pins separately, which is cumbersome and hinders quick adjustment of the adhesive curtain width. Patent documents have addressed this improvement.

[0003] Chinese patent CN219210509U discloses an adhesive coating edge trimmer, including a curtain-type adhesive coating device and two sets of curtain-type adhesive coating devices for use with the curtain-type adhesive coating device. The two sets of curtain-type adhesive coating devices are symmetrically installed on both sides of the curtain-type adhesive coating device. Each curtain-type adhesive coating device is provided with a support plate and an elastic sheet. The device also includes an adjustment component disposed between the two support plates on the two curtain-type adhesive coating devices for synchronously adjusting the bending of the two elastic sheets. This adhesive coating edge trimmer, when used to change the distance between two adjustment plates by bending the elastic sheets, allows for simultaneous bending of the two elastic sheets through the adjustment component. This makes adjusting the distance between the two adjustment plates more convenient, thereby facilitating the adjustment of the width of the adhesive curtain on the curtain-type adhesive coating device and simplifying its operation.

[0004] While the aforementioned patent makes it easier to adjust the distance between the two adjustment plates, thereby enabling more convenient adjustment of the width of the glue curtain on the curtain-type glue coating device, the range of adjustment for the width of the glue curtain is limited, and the width can only be adjusted in small increments. However, during the adjustment process, the regulator will be contaminated with overflowing glue, causing the glue on the regulator to gradually increase, affecting subsequent normal use. The regulator is installed with bolts, making it difficult to disassemble and clean. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an adhesive coating edge adjuster, which solves the problems of limited adjustment range for the width of the adhesive water curtain, only allowing for small-scale width adjustment, and the problem of adhesive overflowing onto the adjuster, gradually increasing the amount of adhesive and affecting subsequent normal use, as well as the difficulty in disassembly and cleaning.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adhesive coating edge trimmer, comprising a curtain-type adhesive coating device and two adjusting plates located below the curtain-type adhesive coating device. The bottom of the curtain-type adhesive coating device is provided with an adhesive outlet. A sealing plate is fixedly connected to one side of each adjusting plate. Fixing plates are fixedly connected to both sides of the front of the curtain-type adhesive coating device. A threaded rod is rotatably connected to one side of the left-side fixing plate via a bearing. One end of the threaded rod passes through the right-side fixing plate and extends to the outside of the right-side fixing plate. Threaded sleeves are threadedly connected to both sides of the surface of the threaded rod. A sliding groove is provided at the front of the curtain-type adhesive coating device. The surface of the threaded sleeve is slidably connected to the sliding groove via a slider. An installation mechanism adapted to the adjusting plates is provided on the threaded sleeve.

[0007] Preferably, the mounting mechanism includes a mounting plate, which is fixedly connected to a threaded sleeve. An L-shaped plate is fixedly connected to the front of the adjusting plate. A limiting through groove adapted to the L-shaped plate is opened at the front of the mounting plate. A moving groove (79) communicating with the limiting through groove is opened on the opposite side of the two mounting plates.

[0008] Preferably, a connecting frame is fixedly connected to the lower front part of the mounting plate, and a limit rod is slidably connected to the front part of the connecting frame through an opening, with a circular plate fixedly connected to one end of the limit rod.

[0009] Preferably, a spring is sleeved on the surface of the limiting rod and between the connecting frame and the circular plate, and a limiting hole adapted to the limiting rod is opened at the front of the L-shaped plate.

[0010] Preferably, the bottom of the curtain-type adhesive coating device is provided with a sealing groove, and the top of the sealing plate is fixedly connected with a sealing plate that matches the sealing groove.

[0011] Preferably, a scale plate is fixedly installed at the front of the curtain-type adhesive coating device and above the fixed plate. Beneficial effects

[0012] This invention provides an adhesive coating edge trimmer. Compared with existing technologies, it has the following advantages:

[0013] (1) This utility model drives two threaded sleeves to move towards the middle at the same time by rotating the threaded rod. The two threaded sleeves will drive two adjusting plates to move towards the middle at the same time through the installation mechanism. The two adjusting plates will drive the sealing plate to move, so that the sealing plate can seal the glue outlet. It can conveniently adjust the two adjusting plates at the same time, making the operation more convenient. It can effectively adjust the width of the glue outlet to a longer range, and effectively adapt to curtains of different widths.

[0014] (2) This utility model allows the limiting rod to be pulled outward from the limiting hole so that the limiting rod no longer jams the L-shaped plate. By moving the adjusting plate upward, the L-shaped plate on the adjusting plate moves to the moving groove and is then pulled outward to remove it. This allows the adjusting plate to be disassembled quickly and is convenient for cleaning. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] Please see Figure 1-4 This utility model provides a technical solution: an adhesive coating edge trimmer, including a curtain-type adhesive coating device 1 and two adjusting plates 2 located below the curtain-type adhesive coating device 1. The bottom of the curtain-type adhesive coating device 1 is provided with an adhesive outlet 8. A sealing plate 10 is fixedly connected to one side of the adjusting plate 2. Fixing plates 3 are fixedly connected to both sides of the front part of the curtain-type adhesive coating device 1. A threaded rod 4 is rotatably connected to one side of the left fixing plate 3 via a bearing. The threads on both sides of the surface of the threaded rod 4 are opposite in direction. One end of the threaded rod 4 passes through the right fixing plate 3 and extends to the outside of the right fixing plate 3. A rotating port adapted to the threaded rod 4 is opened on one side of the other fixing plate 3. Threaded sleeves 5 are threadedly connected to both sides of the surface of the threaded rod 4. A sliding groove 6 is opened at the front part of the curtain-type adhesive coating device 1. The surface of the threaded sleeve 5 is slidably connected to the sliding groove 6 via a slider. An installation mechanism 7 adapted to the adjusting plate 2 is provided on the threaded sleeve 5.

[0022] Furthermore, to facilitate the quick installation and disassembly of the adjusting plate 2, the installation mechanism 7 includes an installation plate 71, which is fixedly connected to the threaded sleeve 5. An L-shaped plate 72 is fixedly connected to the front of the adjusting plate 2. A limiting groove 73 adapted to the L-shaped plate 72 is opened at the front of the installation plate 71. A moving groove 79 connected to the limiting groove 73 is opened on the opposite side of the two installation plates 71. A connecting frame 74 is fixedly connected to the lower front of the installation plate 71. A limiting rod 75 is slidably connected to the front of the connecting frame 74 through an opening. A circular plate 76 is fixedly connected to one end of the limiting rod 75. A spring 77 is sleeved on the surface of the limiting rod 75 between the connecting frame 74 and the circular plate 76. A limiting hole 78 adapted to the limiting rod 75 is opened at the front of the L-shaped plate 72.

[0023] Furthermore, in order to better seal the glue outlet 8, a sealing groove 12 is provided at the bottom of the curtain-type glue coating device 1, and a sealing plate 11 that matches the sealing groove 12 is fixedly connected to the top of the sealing plate 10.

[0024] Furthermore, in order to facilitate observation of the distance the adjustment plate 2 moves, a scale plate 9 is fixedly installed at the front of the curtain-type glue application device 1 and above the fixed plate 3.

[0025] In use, rotating the handle drives the threaded rod 4 to rotate, and the slider in the groove 6 will slide and limit the threaded sleeve 5, causing the threaded rod 4 to move the two threaded sleeves 5 towards the middle. The two threaded sleeves 5 will move the two adjusting plates 2 towards the middle simultaneously through the mounting mechanism 7. By observing the scale value of the scale plate 9, the two adjusting plates 2 are moved to the appropriate position. The adjusting plates 2 will drive the sealing plate 10. By adjusting the glue curtain through the two adjusting plates 2, the two sealing plates 10 will seal the two sides of the glue outlet 8. Adjusting the width of the glue outlet 8, the sealing plate 11 on the sealing plate 10 will be inserted into the sealing groove 12 to prevent glue from overflowing at the sealed position of the glue outlet 8.

[0026] When the adjusting plate 2 needs to be cleaned, by pulling the two circular plates 76, the circular plates 76 will drive the limiting rod 75 to move out of the limiting hole 78, so that the limiting rod 75 is no longer stuck in the L-shaped plate 72. Then, pull the adjusting plate 2 outward, and the L-shaped plate 72 on the adjusting plate 2 will move out of the limiting through groove 73 and the moving groove 79, so that the adjusting plate 2 can be disassembled for cleaning.
