Description

Technical Field

[0001] This utility model relates to the field of gluing machines, and in particular to a multifunctional gluing machine. Background Technology

[0002] A coating machine is a device used to apply adhesive (usually a binder) to the surface of various materials. It is widely used in production and processing, especially in industries such as printing, packaging, and paper product manufacturing. Its main function is to evenly coat the adhesive onto the material surface, ensuring the bonding effect or surface protection of the product.

[0003] A search revealed Chinese Patent Publication No. CN221835094U, which discloses a gluing machine. This gluing machine, through a set of support frame, mounting frame, extrusion roller, adjusting screw, threaded hole and rotary wheel, can adjust the extrusion roller up and down to adjust the distance between the extrusion roller and the gluing roller, which is convenient for gluing wine boxes of different thicknesses. Through the set of sliding groove, sliding block, telescopic spring and glue scraper plate, it can scrape off the raised glue on the surface of the gluing roller, effectively maintaining the thickness of the glue on the surface of the gluing roller, which is convenient for uniform glue application and high-quality adhesive sealing of wine boxes.

[0004] The aforementioned device can only apply glue to one side of the wine box during operation. For products requiring high bonding strength, single-sided application is insufficient to ensure the stability between layers. Furthermore, the device necessitates a second gluing process, impacting work efficiency. Therefore, a multi-functional gluing machine is proposed to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a multi-functional gluing machine, which aims to improve the problem of reduced work efficiency when secondary gluing is applied to products requiring high bonding strength in the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A multifunctional gluing machine includes a worktable, a glue storage box fixedly connected to the bottom surface of the worktable, a glue application roller rotatably connected between the inner walls of the glue storage box, a C-shaped frame fixedly connected to the surface of the worktable, a pressing assembly provided on the inner side of the C-shaped frame, the pressing assembly including a support plate, the support plate being slidably connected between the inner walls of the C-shaped frame, four sets of symmetrically arranged telescopic rods fixedly connected to the bottom surface of the support plate, a mounting frame fixedly connected to the bottom end of the telescopic rods, a pressure roller rotatably connected between the inner walls of the mounting frame, and a return spring elastically connecting the mounting frame and the bottom of the support plate.

[0008] As a further description of the above technical solution:

[0009] The mounting frame has a groove on its side wall, and a guide assembly is provided inside the groove. The guide assembly includes an extension arm, which is slidably connected inside the groove. A side plate is fixedly connected to the end of the extension arm, and a crossbar is fixedly connected between the inner walls of the groove. The crossbar passes through and is slidably connected to the side wall of the extension arm.

[0010] As a further description of the above technical solution:

[0011] A threaded rod is rotatably connected to the surface of the support plate. The threaded rod passes through and is threaded onto the surface of the C-shaped frame. A rotating wheel is fixedly connected to the top end of the threaded rod.

[0012] As a further description of the above technical solution:

[0013] The C-shaped frame has a limiting groove on its side wall, and a limiting block is slidably connected inside the limiting groove. The limiting block is fixedly connected to the side wall of the support plate.

[0014] As a further description of the above technical solution:

[0015] The extension arms are symmetrically arranged in two sets, and a bidirectional lead screw is threaded between the two sets of extension arms. A handwheel is fixedly connected to the outer wall of the bidirectional lead screw.

[0016] As a further description of the above technical solution:

[0017] The sidewall of the side plate is rotatably connected to multiple sets of arrayed rollers.

[0018] As a further description of the above technical solution:

[0019] The reset spring is sleeved on the outer wall of the telescopic rod.

[0022] As a further description of the above technical solution:

[0023] The bottom surface of the workbench is fixedly connected to four sets of symmetrically arranged support legs.

[0024] As a further description of the above technical solution:

[0025] The supporting legs are fixedly connected by reinforcing rods.

[0026] This utility model has the following beneficial effects:

[0027] 1. In this utility model, the pressure of the mounting frame is provided by the reset spring, so that the surfaces of the pressure roller and the coating roller are always in contact. When the motor is started, the coating roller is driven to rotate through its output shaft. The coating roller drives the pressure roller to rotate synchronously, so that the glue inside the glue storage box is evenly coated on the surfaces of the coating roller and the pressure roller. When the product passes between the pressure roller and the coating roller, both sides can be coated with glue at the same time.

[0028] 2. In this utility model, by rotating the handwheel, the handwheel drives the bidirectional lead screw to rotate. The bidirectional lead screw drives the two sets of extension arms to slide inside the groove. The extension arms drive the side plates to move, and the side plates drive the roller to move, thereby adjusting the distance between the two sets of side plates to accommodate products of different widths. The roller fits against the side wall of the product and provides a guiding effect for the product passing between the two sets of side plates, ensuring the stability of the product's position during the gluing process.

[0035] 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.

[0036] Reference Figure 1 - Figure 2 This utility model provides an embodiment of a multi-functional gluing machine, including a worktable 1. Four symmetrically arranged support legs 11 are fixedly connected to the bottom surface of the worktable 1, and reinforcing rods 12 are fixedly connected between the support legs 11. The four sets of support legs 11 and reinforcing rods 12 provide stable support for the worktable 1. A glue storage box 2 is fixedly connected to the bottom surface of the worktable 1, used to store glue for use by a coating roller 21. The coating roller 21 is rotatably connected between the inner walls of the glue storage box 2, and a motor 22 is fixedly connected to the side wall of the glue storage box 2. The output shaft of the motor 22 passes through and is rotatably connected to the inner wall of the glue storage box 2, and is fixedly connected to the end of the coating roller 21. The motor 22 drives the coating roller 21 to rotate through its output shaft, so that the glue inside the glue storage box 2 is evenly coated on the surface of the coating roller 21.

[0037] Reference Figure 1 , Figure 3 A C-shaped frame 3 is fixedly connected to the surface of the workbench 1. The C-shaped frame 3 is a frame that supports and fixes the clamping assembly 4, ensuring clamping stability throughout the glue application process. The clamping assembly 4 is provided on the inner side of the C-shaped frame 3. The clamping assembly 4 includes a support plate 41, which is slidably connected between the inner sidewalls of the C-shaped frame 3. The position of the support plate 41 can be adjusted within the C-shaped frame 3. Four sets of symmetrically arranged telescopic rods 42 are fixedly connected to the bottom surface of the support plate 41. A mounting frame 43 is fixedly connected to the bottom end of the telescopic rods 42. A pressure roller 44 is rotatably connected between the inner walls of the mounting frame 43. The four sets of telescopic rods 42 are used to position the mounting frame 43 and allow the mounting frame 43 to move vertically. The mounting frame 43 and the bottom of the support plate 41 are elastically connected by a return spring 45. The return spring 45 is sleeved on the outer wall of the telescopic rod 42 and provides downward pressure to the mounting frame 43, so that the pressure roller 44 contacts the surface of the coating roller 21. The rotation of the coating roller 21 drives the pressure roller 44 to rotate synchronously, so that the surfaces of the coating roller 21 and the pressure roller 44 are both coated with glue. When the product passes between the pressure roller 44 and the coating roller 21, both sides can be coated with glue at the same time, thereby improving work efficiency. Furthermore, the pressure roller 44 is affected by the thickness of the product and moves upward, the telescopic rod 42 shortens, and the return spring 45 is compressed, so that the product can pass smoothly between the pressure roller 44 and the coating roller 21.

[0038] Reference Figure 1 , Figure 3A threaded rod 46 is rotatably connected to the surface of the support plate 41. The threaded rod 46 passes through and is threaded onto the surface of the C-shaped frame 3. A rotating wheel 47 is fixedly connected to the top of the threaded rod 46, which drives the threaded rod 46 to rotate. The operator can adjust the height of the support plate 41, so that the pressure of the return spring 45 on the product can be adjusted to accommodate products of different thicknesses. A limiting groove 48 is formed in the side wall of the C-shaped frame 3. A limiting block 49 is slidably connected inside the limiting groove 48, and the limiting block 49 is fixedly connected to the side wall of the support plate 41. The limiting groove 48 and the limiting block 49 are used to provide the range of motion of the support plate 41, making the support plate 41 more stable when moving.

[0039] Reference Figure 3 - Figure 4 The side wall of the mounting frame 43 has a groove 410. A guide component 5 is provided inside the groove 410. The guide component 5 includes an extension arm 51. The extension arm 51 is slidably connected inside the groove 410. Two sets of extension arms 51 are symmetrically arranged. A bidirectional lead screw 52 is threaded between the two sets of extension arms 51. A handwheel 53 is fixedly connected to the outer wall of the bidirectional lead screw 52. The extension arm 51 is installed in the mounting frame 43. By connecting with the bidirectional lead screw 52, ​​the bidirectional lead screw 52 is driven to rotate by the handwheel 53, so that the distance between the two sets of extension arms 51 can be adjusted. A side plate 54 is fixedly connected to the end of the extension arm 51. Multiple sets of arrayed rollers 55 are rotatably connected to the side wall of the side plate 54. The movement of the extension arm 51 causes the side plate 54 to move synchronously, so that the rollers 55 on the side wall of the side plate 54 fit against the side wall of the product, thereby providing guidance for the product passing between the two sets of side plates 54 and ensuring the stability of the product's position during the gluing process. A crossbar 56 is fixedly connected between the inner walls of the groove 410. The crossbar 56 passes through and is slidably connected to the side wall of the extension arm 51. The crossbar 56 provides positioning and guidance for the extension arm 51, allowing the extension arm 51 to move stably along the interior of the groove 410.

[0040] Working principle: During use, the operator places the product to be coated between the coating roller 21 and the pressure roller 44. The rotating wheel 47 drives the threaded rod 46 to rotate. The threaded rod 46 moves threadedly on the surface of the C-shaped frame 3, causing the support plate 41 to slide inside the C-shaped frame 3. The support plate 41 drives the telescopic rod 42 and the mounting frame 43 to move. The mounting frame 43 drives the pressure roller 44 to move, thereby adjusting the distance between the pressure roller 44 and the coating roller 21 to accommodate products of different thicknesses.

[0041] The return spring 45 provides downward pressure to the mounting frame 43, ensuring that the pressure roller 44 and the coating roller 21 remain in constant contact. The motor 22 starts and drives the coating roller 21 to rotate via its output shaft. The coating roller 21 then drives the pressure roller 44 to rotate synchronously, evenly coating the adhesive inside the glue storage box 2 onto the surfaces of the coating roller 21 and the pressure roller 44. When the product passes between the pressure roller 44 and the coating roller 21, both sides can be coated simultaneously.

[0042] Simultaneously, the operator can rotate handwheel 53, which drives the bidirectional lead screw 52 to rotate. The bidirectional lead screw 52 causes two sets of extension arms 51 to slide inside the groove 410. The extension arms 51 drive the side plates 54 to move, and the side plates 54 drive the roller 55 to move, thereby adjusting the distance between the two sets of side plates 54 to accommodate products of different widths. The roller 55 is in contact with the side wall of the product, providing guidance for the product passing between the two sets of side plates 54 and ensuring the stability of the product's position during the gluing process.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
