Description

Technical Field

[0001] This utility model relates to the field of paper box production technology, and in particular to a glue coating device for paper box production. Background Technology

[0002] With the continuous development of the global economy and the continuous expansion of the consumer market, the demand for packaging for various products is increasing day by day. As a common, practical and environmentally friendly packaging form, paper boxes are widely used in many industries such as food, beverages, electronic products, cosmetics, and pharmaceuticals, and their market size continues to expand.

[0003] In the paper box production process, the bonding quality directly affects its performance and appearance. Therefore, it is crucial to pay attention to the glue application process. Existing glue application equipment typically employs simple mechanical application methods or directly uses roller glue applicators. During the application process, due to the mismatch between the glue supply speed and the paper box's moving speed, especially when the glue roller contacts the paper box and handles the pre-reserved folds, the application is prone to unevenness and glue overflow, resulting in inconsistent glue layer thickness or localized glue gaps. This reduces the glue application quality and makes it difficult to meet the diverse needs of modern paper box production. In view of this, this application proposes a glue application device for paper box production. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the glue coating roller in the prior art is prone to uneven thickness when applying glue to paper boxes, and to propose a glue coating device for paper box production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A gluing device for paper box production includes a machine body, an operation panel on the side wall of the machine body, a plurality of supporting feet installed at the bottom of the machine body, a worktable on the top of the machine body, and a controller installed at the upper end of the worktable.

[0007] Two guard plates are installed at the upper end of the workbench, and a glue-applying roller is arranged between the two guard plates. A liquid storage tank is arranged above the glue-applying roller. Support plates are fixedly connected to both ends of the liquid storage tank, and the bottom of the support plate is fixedly connected to the top of the corresponding guard plate. Adjustment mechanisms are respectively arranged on the two support plates on the same side of the liquid storage tank, and the two adjustment mechanisms are connected to a scraper.

[0008] Preferably, each of the two guard plates has a storage slot, and each of the two storage slots is equipped with a hydraulic cylinder. An assembly block is fixedly connected to the telescopic end of each of the two hydraulic cylinders.

[0009] Preferably, a drive shaft is provided through the glue-applying roller, and one end of the drive shaft is rotatably connected to an assembly block on one side, while the other end of the drive shaft passes through the assembly block on the other side and is connected to a drive mechanism.

[0010] The coating roller has multiple guide grooves circumferentially, and the guide grooves are designed to be corrugated.

[0011] Preferably, the drive mechanism includes a motor, the output shaft of which is connected to a transmission shaft via a coupling, and telescopic frames are connected to the two side walls of the motor, with the bottom of both telescopic frames connected to the worktable.

[0012] Preferably, the bottom of the liquid storage tank is connected to multiple nozzles, and each nozzle is equipped with a solenoid valve at the connection point with the liquid storage tank.

[0013] Multiple nozzles are positioned directly above the coating roller, and the nozzles are arranged at equal intervals.

[0014] Preferably, the adjusting mechanism includes a threaded rod, one end of which is fixedly connected to a knob, and the other end of which is rotatably connected to a support plate corresponding to the position.

[0015] A nut is fitted onto the threaded rod, and a connecting block is fixedly connected to the nut. The side wall of the connecting block is fixedly connected to the end of the scraper.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model uses a hydraulic cylinder to drive the transmission shaft, which can adjust the distance between the glue-applying roller and the cardboard box. This ensures that the glue-applying roller maintains close contact with the surface of the cardboard box during the glue-applying process. Multiple guide grooves are circumferentially formed on the surface of the glue-applying roller. As the glue-applying roller rotates, a certain amount of glue can be contained in the guide grooves, preventing excessive overflow due to pressure or changes in the contact surface when contacting the uneven areas of the cardboard box. At the same time, relying on the viscosity of the glue itself, the contact area between the glue-applying roller and the folded recesses of the cardboard box is increased. This eliminates the need for repeated application to compensate for insufficient glue or uneven application, saving application time and improving the production quality and overall efficiency of the cardboard box.

[0018] 2. This utility model, through the threaded rod, nut, and connecting block, allows the scraper to move when the knob is turned, adjusting the gap between the scraper end and the coating roller. This adjusts the amount of glue dispensed when the coating roller contacts the cardboard box, preventing uneven glue thickness caused by mismatched coating speeds. Simultaneously, the arc-shaped surface at the upper end of the scraper collects the glue scraped from the coating roller and reapplies it to the coating roller surface during continuous rotation. This allows for precise control of the glue supply, reducing glue waste and improving the practicality of the device. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] This utility model provides a technical solution: such as Figure 1 As shown, a gluing device for paper box production includes a body 1. An operation panel 11 is provided on the side wall of the body 1. Multiple support feet 12 are installed at the bottom of the body 1. The upper end of the support feet 12 is connected to the internal thread groove opened at the bottom of the body 1 through a threaded post. By turning the support feet 12, the length of the threaded post extending out of the body 1 can be adjusted, thereby flexibly adjusting the height of the edge of the body 1 to ensure that the body 1 remains stable during operation. A worktable 13 is provided on the top of the body 1. A controller 14 is installed on the upper end of the worktable 13. It should be noted that the controller 14 is electrically connected to the solenoid valves on the operation panel 11, hydraulic cylinder 22, motor 41, and nozzle 52, respectively. The operation of the corresponding components can be realized through the operation panel 11.

[0026] like Figure 2As shown, two guard plates 2 are installed on the upper end of the workbench 13. Each guard plate 2 has a storage slot 21, and each storage slot 21 is equipped with a hydraulic cylinder 22. Assembly blocks 23 are fixedly connected to the telescopic ends of the two hydraulic cylinders 22.

[0027] In addition, a glue-applying roller 3 is provided between the two guard plates 2. A drive shaft 31 is provided through the glue-applying roller 3. One end of the drive shaft 31 is rotatably connected to the assembly block 23 on one side. The other end of the drive shaft 31 passes through the assembly block 23 on the other side and is connected to a drive mechanism 4. The drive mechanism 4 includes a motor 41. The output shaft of the motor 41 is connected to the drive shaft 31 through a coupling 43. Telescopic frames 42 are respectively connected to the two side walls of the motor 41. The bottom of the two telescopic frames 42 is connected to the worktable 13. The glue-applying roller 3 has multiple guide grooves 32 circumferentially. The guide grooves 32 are designed to be corrugated.

[0028] Specifically, the height of the transmission shaft 31 can be adjusted by the hydraulic cylinder 22, thereby adjusting the distance between the glue-applying roller 3 and the cardboard box. It should be noted that during the up-and-down movement of the glue-applying roller 3, the telescopic frame 42 itself can be adjusted in length to ensure that the output shaft of the motor 41 is aligned with the axis of the transmission shaft 31. When the motor 41 is started, the output shaft of the motor 41 can drive the transmission shaft 31 to rotate through the coupling 43. The glue-applying roller 3 rotates synchronously to apply glue to the cardboard box placed on the workbench 13.

[0029] Furthermore, when the coating roller 3 applies glue to the cardboard box, the glue is transferred to the surface of the cardboard box along the contact surface of the coating roller 3. Since the coating roller 3 has multiple guide grooves 32 circumferentially and the width of the guide grooves 32 is small, the glue will flow to a lower energy state due to the surface tension. Thus, the guide grooves 32 can attract and guide the glue adhering to the surface of the coating roller 3. Through the accommodation of the guide grooves 32, the accumulation of glue on the roller surface of the coating roller 3 is reduced. Furthermore, relying on the viscosity of the glue itself, when dealing with the fold seams reserved at the fold of the cardboard box, the excess glue on the surface of the cardboard box can be guided and the fold seams can be filled, improving the uniformity of the glue layer on the surface of the cardboard box and improving the continuity and stability of the coating.

[0030] like Figure 3 As shown, a liquid storage tank 5 is provided above the glue coating roller 3. Support plates 51 are fixedly connected to both ends of the liquid storage tank 5, and the bottom of the support plates 51 is fixedly connected to the top of the corresponding guard plate 2. Multiple nozzles 52 are connected to the bottom of the liquid storage tank 5. Solenoid valves are provided at the connection points between the multiple nozzles 52 and the liquid storage tank 5. The multiple nozzles 52 are all located directly above the glue coating roller 3, and the multiple nozzles 52 are arranged at equal intervals. By opening and closing the solenoid valves at the bottom of the liquid storage tank 5, the amount of glue sprayed by the nozzles 52 can be controlled, thereby flexibly adjusting the glue supply speed.

[0031] like Figure 4 As shown, two support plates 51 on the same side of the liquid storage tank 5 are respectively provided with adjustment mechanisms 6. The two adjustment mechanisms 6 are connected to a scraper 7. The adjustment mechanism 6 includes a threaded rod 61, and one end of the threaded rod 61 is fixedly connected to a knob 63. The other end of the threaded rod 61 is rotatably connected to the support plate 51 corresponding to the position. A nut 62 is sleeved on the threaded rod 61, and a connecting block 64 is fixedly connected to the nut 62. The side wall of the connecting block 64 is fixedly connected to the end of the scraper 7.

[0032] It should be noted that turning the knob 63 can drive the threaded rod 61 to rotate. Since the two ends of the scraper 7 are respectively connected to the corresponding connecting blocks 64, and one side of the connecting block 64 is sleeved on the nut 62, the scraper 7 can play a certain limiting role on the nuts 62 on both sides, restricting the rotation of the nuts 62. As the threaded rod 61 rotates, the nuts 62 move along the direction set by the threaded rod 61, thereby adjusting the position of the scraper 7 and adjusting the gap between the side wall of the scraper 7 and the glue coating roller 3, thereby controlling the glue layer thickness on the surface of the glue coating roller 3. Furthermore, relying on the arc-shaped surface set at the upper end of the scraper 7, the excess glue scraped off the glue coating roller 3 can be collected and replenished in uneven areas during the subsequent rotation of the glue coating roller 3, ensuring the uniformity of the glue coating roller 3 surface while improving the utilization rate of glue.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
