Description

Technical Field

[0001] This utility model belongs to the field of paper printing technology, specifically relating to a glue scraping structure for a laminating machine. Background Technology

[0002] In the laminating process, the amount of glue used is a crucial factor. The squeegee mechanism precisely controls the amount of glue applied. For example, when paper or other materials pass through the laminating machine, the squeegee scrapes away excess glue from the glue roller, ensuring the glue is evenly applied to the material surface. This prevents uneven bonding, wrinkles, and bulges caused by excessive glue. Too much glue can lead to excessive adhesion during subsequent processing or use, damaging the materials or causing glue overflow and contaminating the machine and surrounding environment. Currently, most common squeegee mechanisms are single-blade structures. During operation, the bottom of the squeegee scrapes away excess glue. However, excess glue often accumulates on one side of the squeegee. When excessive glue accumulates, it may flow down from both sides of the glue roller, affecting the laminating process. Utility Model Content

[0003] This utility model provides a scraper structure for a glue-coating machine, which can absorb excess glue accumulated on one side of the scraper, reducing the interference caused by excessive glue accumulation on one side of the scraper to the glue roller during the glue application process. At the same time, it can replenish the glue when there is a local shortage of glue on the surface of the glue roller, which helps to improve the uniformity of glue application on the glue roller.

[0004] This utility model provides the following technical solution: a glue scraping structure for a glue laminating machine, including a scraper, an arc-shaped extension plate fixedly connected to the bottom of the scraper, a conveying pipe provided on one side of the scraper, and an electric suction head fixedly connected to the bottom of the conveying pipe, several electric heating plates fixedly connected to the outside of the conveying pipe, a glue storage box fixedly connected to the top of the conveying pipe, a glue feeding pipe embedded inside the scraper, a glue outlet pipe fixedly connected to the bottom of the glue feeding pipe, and the glue outlet pipe penetrating into the interior of the arc-shaped extension plate, a sealing plate hinged to the bottom of the glue outlet pipe, a fixed base fixedly connected to one side of the conveying pipe, and a liquid level monitor fixedly connected inside the fixed base, a PLC controller fixedly connected to one side of the glue storage box, and the PLC controller connected to the electric suction head and the liquid level monitor via a connecting cable.

[0005] The top of the scraper is fixedly connected to a connecting seat, and both sides of the connecting seat are fixedly connected to mounting seats.

[0006] The outer side of the arc-shaped extension plate is fixedly connected to a counterweight arc plate.

[0007] The outer side of the arc-shaped extension plate is fixedly connected to a micro drive rod, and the output end of the micro drive rod extends through the interior of the dispensing tube.

[0008] A universal ball is rotatably connected between the top of the sealing plate and the output end of the micro drive rod.

[0009] The top of the glue delivery tube is fixedly connected to a connecting tube, and the other end of the connecting tube extends into the interior of the delivery tube, with the inner cavity of the delivery tube connected to the connecting tube.

[0010] The bottom of the glue storage box is fixedly connected to the outside of the delivery pipe.

[0011] The top of the glue storage box is threaded with a sealing cap.

[0012] The beneficial effects of this utility model are as follows: With the cooperation of the liquid level monitor, electric suction head, glue feeding tube, glue dispensing tube, arc extension plate, and PLC controller, excess glue accumulated on one side of the scraper can be absorbed during the operation of the scraper structure, so that the glue on one side of the scraper is kept within a suitable accumulation range, reducing the interference caused by excessive glue accumulation on one side of the scraper to the glue roller during the glue feeding and coating process. At the same time, when there is a local lack of glue on the surface of the glue roller, local glue replenishment can be performed, so that the glue roller surface maintains a uniform glue during operation, which helps to improve the uniformity of glue coating on the glue roller.

[0019] Please see Figures 1-4 The present invention provides the following technical solution: a glue scraping structure for a glue laminating machine, including a scraper 1, an arc-shaped extension plate 11 fixedly connected to the bottom of the scraper 1, a conveying pipe 2 on one side of the scraper 1, and an electric suction head 21 fixedly connected to the bottom of the conveying pipe 2, a plurality of electric heating plates 22 fixedly connected to the outside of the conveying pipe 2, a glue storage box 23 fixedly connected to the top of the conveying pipe 2, a glue feeding pipe 3 embedded inside the scraper 1, a glue outlet pipe 31 fixedly connected to the bottom of the glue feeding pipe 3, and the glue outlet pipe 31 penetrating into the interior of the arc-shaped extension plate 11, a sealing plate 32 hinged to the bottom of the glue outlet pipe 31, a fixing seat 41 fixedly connected to one side of the conveying pipe 2, a liquid level monitor 4 fixedly connected inside the fixing seat 41, a PLC controller 5 fixedly connected to one side of the glue storage box 23, and the PLC controller 5 connected to the electric suction head 21 and the liquid level monitor 4 via a connecting line.

[0020] In this implementation scheme: the scraper 1, in cooperation with the arc-shaped extension plate 11, forms the scraping assembly in the entire scraping mechanism. The scraper 1 is the connecting component of the entire scraping assembly. Simultaneously, the scraper 1 is used to scrape the adhesive off the glue roller. The arc-shaped extension plate 11 extends the scraping path of the entire scraping assembly on the glue roller, which helps to smooth the surface of the glue roller. The conveying pipe 2 located on one side of the scraper 1, in cooperation with the electric suction head 21, is used to remove adhesive accumulated on the scraper 1 during the scraping process. The adhesive on one side is sucked out to reduce the amount of adhesive accumulated on the scraper 1 side, which helps to reduce the interference of adhesive accumulation on the scraper 1 during the scraping process. The electric heating plate 22 located outside the conveying pipe 2 is used to heat the inner cavity of the conveying pipe 2 to prevent the adhesive from solidifying inside the conveying pipe 2. The adhesive storage box 23 is used to provide temporary storage space for the sucked-out adhesive. The adhesive delivery pipe 3, in conjunction with the adhesive outlet pipe 31, is used to transport the adhesive in the conveying pipe 2 to the inside of the arc-shaped extension plate 11, which is used to fill any gaps in the adhesive on the surface of the glue roller. The level is replenished in time, and the fixing seat 41 located on one side of the delivery pipe 2 is used to provide a connection for the installation of the level monitor 4. During the operation of the scraping structure, the level monitor 4 detects the amount of glue accumulated on one side of the scraper 1 in real time, and sends the monitoring data to the PLC controller 5 in real time. When the data sent by the level monitor 4 exceeds the preset value inside the PLC controller 5, the PLC controller 5 sends a command to the electric suction head 21 to start working. At this time, the electric suction head 21 absorbs the glue accumulated below, and During this process, the liquid level monitor 4 continuously monitors the amount of adhesive accumulated on one side of the scraper 1 in real time. When the monitoring data of the liquid level monitor 4 returns to the preset value of the PLC controller 5, the PLC controller 5 sends a stop operation command to the electric suction head 21. When the liquid level monitor 4 detects that there is a local shortage of adhesive on the glue roller, the sealing plate 32 can be flipped to one side to allow the adhesive in the glue outlet pipe 31 to flow out to the outside, thus replenishing the adhesive on the glue roller. At this time, the arc-shaped extension plate 11 can scrape the surface of the glue roller flat.

[0021] A connecting seat 12 is fixedly connected to the top of the scraper 1, and mounting seats 121 are fixedly connected to both sides of the connecting seat 12; wherein the connecting seat 12, in cooperation with the mounting seats 121, forms a connecting component for connecting the scraper 1 between laminating machines.

[0022] A counterweight arc plate 13 is fixedly connected to the outer side of the arc-shaped extension plate 11; the counterweight arc plate 13 serves as a counterweight.

[0023] A micro drive rod 321 is fixedly connected to the outer side of the arc-shaped extension plate 11, and the output end of the micro drive rod 321 extends into the interior of the dispensing tube 31. A universal ball 322 is rotatably connected between the top of the sealing plate 32 and the output end of the micro drive rod 321. The micro drive rod 321 is used to drive the sealing plate 32 to rotate, and a connection line is provided between the micro drive rod 321 and the PLC controller 5. The universal ball 322 is used to provide a carrier for the connection between the top of the sealing plate 32 and the output end of the micro drive rod 321.

[0024] The top of the glue delivery tube 3 is fixedly connected to a connecting tube 33, and the other end of the connecting tube 33 extends into the interior of the delivery tube 2, and the inner cavity of the delivery tube 2 is connected to the connecting tube 33; wherein the connecting tube 33 is used to provide a carrier for communication between the delivery tube 2 and the glue delivery tube 3.

[0025] A reinforcing base 24 is fixedly connected between the bottom of the glue storage box 23 and the outside of the delivery pipe 2; the glue storage box 23 plays a reinforcing role.

[0026] The top of the glue storage box 23 is threaded with a sealing cap 231; the sealing cap 231 is used to seal the top of the glue storage box 23.

[0027] The working principle and usage process of this utility model are as follows: When the laminating machine is working, the scraper 1 and the arc-shaped extension plate 11 scrape off the glue on the surface of the glue roller. At this time, the liquid level monitor 4 detects the amount of glue accumulated on one side of the scraper 1 in real time and sends the monitoring data to the PLC controller 5 in real time. When the data sent by the liquid level monitor 4 exceeds the preset value inside the PLC controller 5, the PLC controller 5 sends a start command to the electric suction head 21. After receiving the start command, the electric suction head 21 absorbs the accumulated glue below. During this process, the liquid level monitor 4 holds... The amount of adhesive accumulated on one side of the scraper 1 is continuously monitored in real time. When the monitoring data of the liquid level monitor 4 returns to the preset value of the PLC controller 5, the PLC controller 5 sends a stop command to the electric suction head 21. When the liquid level monitor 4 detects that there is a local shortage of adhesive on the glue roller, the PLC controller 5 sends a working command to the micro drive rod 321. At this time, the micro drive rod 321 can drive the sealing plate 32 to flip to one side, so that the adhesive in the glue outlet tube 31 flows out to the outside to replenish the adhesive on the glue roller. At this time, the arc extension plate 11 can scrape the surface of the glue roller.
