Technical Field

[0001] This utility model relates to the field of adhesive application technology, and more specifically to adhesive application equipment that can apply adhesive evenly. Background Technology

[0002] Self-adhesive paper is an industrial paper product made by coating high-strength white cardboard with adhesive. It is widely used in logistics labels, product identification and other fields. The production process involves professional processes such as silicone coating, lamination and hot melt adhesive bonding. During its processing, adhesive needs to be applied to the base paper for lamination.

[0003] Chinese utility model patent CN221108754U discloses a method for uniformly coating self-adhesive paper, which includes "a frame, with paper feeding rollers rotatably connected to both sides of the bottom of the inner wall of the frame, a glue storage tank fixedly connected to one side of the top of the frame, a conveying pump fixedly installed on one side of the top of the inner wall of the frame, the output end of the conveying pump fixedly connected to a glue distribution box, a first cylinder fixedly installed in the middle of the top of the inner wall of the frame, a mounting base fixedly connected to the bottom of the first cylinder, a flattening roller rotatably connected to the inner wall of the mounting base, and a second cylinder fixedly installed at one end of the front and one end of the back of the frame, with a cutting blade fixedly connected to one end of each of the two second cylinders through the inner wall of the frame." However, the cutting blade is prone to wear due to long-term friction with glue and paper tape edges. When scraping off excess glue after wear, burrs or glue threads are produced. These glue threads may adhere to the paper tape surface or mix with recycled glue, causing secondary pollution and hindering the continuous use of the equipment. Summary of the Invention

[0004] The purpose of this invention is to provide a glue-applying device that can apply glue evenly, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a glue-applying device capable of uniform application, comprising a support base for support, an electric conveyor belt for conveying the coated item being applied is mounted on the top of the support base, a housing is fitted on the outer wall of the support base, a glue-applying roller body is fixedly connected to the bottom wall of the housing, and an installation groove is provided in the inner wall of the housing. The inner wall of the mounting groove is provided with a switching component for switching the scraper blade.

[0006] Preferably, the switching component includes a control plate slidably connected to the mounting slot, and the control plate has a U-shaped cross-section. Control cavities are provided on the inner walls of both ends of the control plate. The control cavities are used to guide the up and down movement of the scraping blade. Two fixing blocks are symmetrically fixed in the inner wall of the control cavity, and the top of each fixing block is fixedly connected to a wedge-shaped block extending forward.

[0007] Preferably, two fixed rods are symmetrically slidably connected on the outer wall of the control board, and a return spring is sleeved on the outer wall of the fixed rods.

[0008] Preferably, the switching assembly further includes a guide rod slidably connected in the control cavity, the width of the guide rod being less than the length of the wedge block, the two ends of the guide rod being slidably connected to the two control cavities respectively, and two guide rods being symmetrically arranged; The bottom end of the guide rod is fixedly connected to a support plate, and a leveling blade is slidably connected to the bottom end of the support plate. The outer walls of both the front and rear ends of the leveling blade are made of magnetic material, and the leveling blade and the bottom end of the support plate are magnetically connected.

[0009] To achieve stable switching of the scraping blade: The configuration is further defined as follows: the two guide rods are initially located at the lower and upper ends of the two wedges, respectively, and the length of the bottom surface of the wedge is less than the length of the top inclined surface of the wedge.

[0010] By adopting the above technical solution, when the guide rod at the top of the wedge moves downward, the scraper below the guide rod gradually comes into contact with the paper and squeezes the wedge, causing the control plate to move to the left. While the control plate continues to move to the left, the other guide rod, which is restricted at the bottom of the wedge, will be at the very end of the wedge. At this time, the guide rod will quickly return to its original position by the tension spring, while the downward-moving guide rod will enter the bottom of the wedge and be locked by the reset of the control plate. At this time, the scrapers on the two guide rods are switched.

[0011] Preferably, a push rod is fixedly connected to the top end of each of the two guide rods. The push rod slides through the top end of the housing and is used to trigger the movement of the guide rod. A control console is fixedly connected to the top of the housing. A sliding cavity for sliding the push rod is opened in the inner wall of the control console. A positioning rod is fixedly connected to the inner wall of the sliding cavity. The outer wall of the positioning rod is slidably connected to the inner wall of the push rod. The bottom end of the positioning rod is connected to the inner wall of the push rod through a tension spring. A paddle is fixedly connected to the outer wall of the push rod. The paddle is slidably connected to the control console.

[0012] To expand the use of the leveling blade: The tool is further configured such that: slots are provided at both the left and right ends of the scraper, and a plug-in block is inserted into the slot and magnetically connected to the outer wall of the scraper, and an extension blade is fixedly connected to the end of the plug-in block away from the scraper; The outer wall of the housing is provided with a disassembly port that communicates with the mounting groove, and a sealing door is hinged to the disassembly port.

[0013] By adopting the above technical solution, after the leveling blade is switched, the sealed door can be opened and the leveling blade can be manually pulled out. Auxiliary blades that need to be extended can be inserted on the left and right sides of the leveling blade, making it convenient for workers to use.

[0014] The beneficial effects of this utility model are as follows: In this invention, by setting the switching component, when the switching flat knife comes into contact with the paper, it triggers the retraction of the old flat knife, which facilitates stable switching and use of the blades, eliminates the need to stop the machine for disassembly, facilitates continuous use of the equipment, and avoids worn blades affecting the coating effect. In this invention, the expandable scraper blade allows for the installation of auxiliary blades of different lengths according to the size of different papers, thereby increasing the applicability of the equipment.

[0015] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0026] The computer software involved in the hardware carriers such as the electric conveyor belt equipment and the coating roller body in the technical solution is software technology known to those skilled in the art. It is merely applied to the aforementioned hardware carriers. In other words, the computer software portion of the technical solution is an essential technical feature for solving the aforementioned technical problem, constituting a necessary technical feature for the technical problem solved by this application, but it is not a differentiating technical feature or a point of technical improvement. The applicant has not made any technical improvements to the computer software portion involved in the aforementioned related hardware carriers, nor is it a key technical point of the invention.

[0027] Therefore, the "electric conveyor belt equipment" and "glue roller body" involved in this application are physical functional modules that combine computer software programs or protocols in the prior art with the hardware carrier of this application. The computer software programs involved in these physical functional modules are all technologies known to those skilled in the art and are not improvements of this application.

[0028] The working process of this adhesive application equipment, which can evenly apply adhesive, is as follows: First, the electric conveyor belt device 1 drives the paper to be processed through the glue roller 3 body via the conveyor belt, which performs glue application on the paper surface. Then, the glued paper comes into contact with the scraper blade 58 to scrape the glue layer of different thicknesses. After the equipment has been running for a certain period of time, the operator can manually press the lever 513 above the unused scraper 58. The lever 513 moves the push rod 59 downward while pulling the tension spring. The push rod 59 moves down through the guide rod 56 to squeeze the wedge block 54. At this time, the control plate 51 moves to the left continuously when the wedge block 54 is pressed, until the guide rod 56 moves to the outermost edge of the current wedge block 54. The guide rod 56 at the bottom of the other wedge block 54 is no longer blocked by it and quickly returns to its original position through the extension spring. The currently pressed guide rod 56 enters the bottom of the control cavity 52. ​​At this time, there is no pressure from the guide rod 56. The control plate 51 quickly returns to its original position through the reset spring and locks the guide rod 56 in the current position. At this time, the scraper 58 below the guide rod 56 contacts the paper and continues the smoothing operation. In addition, staff can manually open the sealing door 7 and manually remove the scraper blade 58 from the disassembly port 6 for disassembly and replacement. When the equipment is in use, staff can insert the extension blade 515 into the slot 514 to extend the length of the scraper blade 58 to accommodate the width of different papers.
