Description

Technical Field

[0001] The utility model relates to the technical field of corrugated carton gluing, and more specifically, the utility model relates to a uniform gluing device in the production of corrugated cartons. Background Art

[0002] A corrugated carton is made by die-cutting, indentation, nailing or gluing corrugated cardboard. During the production and processing of corrugated cartons, it is necessary to uniformly apply glue on the surface of the cardboard through a gluing device for subsequent processing operations of the cartons.

[0003] The utility model patent with the patent application number CN202321387179.1 discloses a gluing device for corrugated paper production, including a base. A conveyor is arranged on the inner side wall of the base, and a machine frame is arranged on the top of the base. The advantage of this structure is that it can make the glue applicator more evenly apply glue on the corrugated paper and use a scraper to level the glue, effectively improving the gluing efficiency of the corrugated paper.

[0004] However, in actual use of this structure, after the glue remaining at the glue applicator head solidifies, it is easy to cause blockage at the glue applicator head, which in turn makes it difficult to discharge the glue and affects the gluing efficiency of the cardboard. In view of this, the utility model proposes a uniform gluing device in the production of corrugated cartons. Summary of the Utility Model

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides a uniform gluing device in the production of corrugated cartons to solve the problems raised in the above background art.

[0006] To achieve the above object, the utility model provides the following technical solution: A uniform gluing device in the production of corrugated cartons includes a conveyor and a support frame installed on the conveyor. A gluing box is arranged inside the support frame. A plurality of anti-blocking glue applicator head structures are arranged at the bottom of the gluing box. Two electric push rods are arranged on the top of the support frame. The output ends of the electric push rods penetrate through the support frame, and the output ends of the electric push rods are connected to the upper surface of the gluing box inside the support frame. A support plate is arranged on one side of the support frame, and a glue storage box is arranged on the top of the support plate. One end of the glue storage box is provided with a glue delivery hose. One end of the glue delivery hose is communicated with the glue storage box, and the other end of the glue delivery hose is communicated with the gluing box.

[0007] It can be seen that in the above structure, the conveyor is used to convey the cardboard used for corrugated cardboard. The glue inside the glue storage box can enter the inside of the gluing box through the glue delivery hose and be discharged through the glue outlet head to achieve the gluing operation on the cardboard. The electric push rod can ensure that the glue outlet head performs the gluing operation on the surface of the cardboard.

[0008] To avoid the glue remaining inside the glue outlet head causing blockage of the glue outlet head and affecting the discharge of glue, preferably, the anti-blocking glue application head structure includes a sleeve. The sleeve is located at the bottom of the glue application box and is communicated with the glue application box. A glue outlet head is slidably arranged inside the sleeve. A fixing block is arranged at the top of the glue outlet head inside the sleeve, and connecting rods are arranged at both ends of the fixing block. A dredging rod is arranged at the bottom of the fixing block. A circular plate is arranged on the outer wall of the top end of the glue outlet head. A support block is arranged at the bottom of the circular plate on the inner wall of the sleeve. A tension spring is arranged between the circular plate and the support block. The fixing block is fixedly installed inside the sleeve through the connecting rod. The dredging rod is fixedly installed at the bottom of the fixing block, and the outer diameter of the dredging rod is smaller than the inner diameter of the bottom end of the glue outlet head. The support block is fixedly installed at the inner wall of the sleeve. The top end and the bottom end of the tension spring are respectively fixedly connected to the bottom of the circular plate and the top of the support block.

[0009] To achieve the effect of uniform glue application on the surface of the cardboard, preferably, two support seats are arranged on one side of the glue outlet head at the bottom of the glue application box, and a glue spreading roller is arranged between the two support seats. The glue spreading roller is rotatably connected between the two support seats.

[0010] The technical effects and advantages of the present utility model:

[0011] 1. By setting the anti-blocking glue application head structure, the glue outlet head extends upward inside the sleeve, which can make the tension spring in a stretched state and make the dredging rod at the bottom of the fixing block extend outward from the glue outlet head. The dredging rod can extrude the residual glue inside the glue outlet head and play a role in dredging, thereby preventing blockage at the glue outlet head due to glue solidification.

[0012] 2. By making the glue spreading roller fit on the surface of the cardboard and making the glue spreading roller rotate between the two support seats, the glue on the surface of the cardboard can be evenly smoothed, achieving the effect of uniform glue application and improving the uniformity of glue application on the surface of the cardboard.

Detailed implementation manners

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] As shown in the attached Figures 1-5 A uniform glue application device in the production of corrugated cardboard boxes includes a conveyor 1 and a support frame 2 installed on the conveyor 1. Inside the support frame 2, there is a glue application tank 3. At the bottom of the glue application tank 3, there are several anti-blocking glue outlet head structures. On the top of the support frame 2, there are two electric push rods 4. The output ends of the electric push rods 4 penetrate through the support frame 2, and the output ends of the electric push rods 4 are connected to the upper surface of the glue application tank 3 inside the support frame 2. On one side of the support frame 2, there is a support plate 5, and on the top of the support plate 5, there is a glue storage tank 6. At one end of the glue storage tank 6, there is a glue delivery hose 7. One end of the glue delivery hose 7 is communicated with the glue storage tank 6, and the other end of the glue delivery hose 7 is communicated with the glue application tank 3.

[0021] Specifically, in this structure, when applying glue to a corrugated cardboard box, the cardboard used for the corrugated cardboard box is placed on the conveyor 1 for transportation. During the transportation process, the electric push rod 4 drives the glue application tank 3 to extend downward, so that the anti-blocking glue outlet head structure at the bottom of the glue application tank 3 fits on the surface of the cardboard. The glue inside the glue storage tank 6 is transported to the inside of the glue application tank 3 for storage through the glue delivery hose 7, and the glue inside the glue application tank 3 is injected onto the surface of the cardboard through multiple anti-blocking glue outlet head structures, thereby realizing the glue application operation during the production of corrugated cardboard boxes.

[0022] Combined with the attached Figure 1 、 2As shown in Figures 4, 5, the anti-clogging glue application head structure includes a sleeve 8, which is at the bottom of the glue application tank 3 and communicates with the glue application tank 3. A glue outlet head 9 is slidably arranged inside the sleeve 8. A fixing block 10 is arranged at the top of the glue outlet head 9 inside the sleeve 8, and connecting rods 11 are arranged at both ends of the fixing block 10. A dredging rod 12 is arranged at the bottom of the fixing block 10. A circular plate 13 is arranged on the outer wall of the top end of the glue outlet head 9. A support block 14 is arranged at the bottom of the circular plate 13 on the inner wall of the sleeve 8. A tension spring 15 is arranged between the circular plate 13 and the support block 14. The fixing block 10 is fixedly installed inside the sleeve 8 through the connecting rod 11. The dredging rod 12 is fixedly installed at the bottom of the fixing block 10, and the outer diameter of the dredging rod 12 is smaller than the inner diameter of the bottom end of the glue outlet head 9. The support block 14 is fixedly installed at the inner wall of the sleeve 8. The top and bottom ends of the tension spring 15 are respectively fixedly connected to the bottom of the circular plate 13 and the top of the support block 14.

[0023] Specifically, in this structure, it is possible to avoid the situation that the outlet of the glue outlet head 9 is blocked due to the solidification of the glue. Specifically, when the glue is discharged, the glue inside the glue application tank 3 enters the inside of the sleeve 8 and then enters the inside of the glue outlet head 9 through the sleeve 8 to realize the flow of the glue.

[0024] Once the glue at the glue outlet head 9 solidifies and is blocked, when the electric push rod 4 drives the glue application tank 3 to extend downward, the glue outlet head 9 contacts the surface of the cardboard and extends upward inside the sleeve 8. At this time, the tension spring 15 is in a stretched state. When the glue outlet head 9 extends upward, the dredging rod 12 at the bottom of the fixing block 10 can extend outward from the glue outlet head 9. The dredging rod 12 can dredge the glue outlet head 9, thereby preventing the glue outlet head 9 from being blocked due to the solidification of the glue. After the glue application tank 3 extends upward under the action of the electric push rod 4, the tension spring 15 returns to its original position after being stretched, so that the dredging rod 12 can return to its initial position to ensure that the glue can be discharged.

[0025] In a specific embodiment, as shown in the attached Figure 2 、 3 figure, two support seats 16 are arranged on one side of the bottom of the glue application tank 3 where the glue outlet head 9 is located, and a glue spreading roller 17 is arranged between the two support seats 16. The glue spreading roller 17 is rotatably connected between the two support seats 16.

[0026] Specifically, in this structure, after the glue outlet head 9 applies glue to the surface of the cardboard, in order to ensure the uniformity of the glue application, as the cardboard is driven by the conveyor 1, the glue spreading roller 17 will be attached to the surface of the cardboard. The glue spreading roller 17 rotates between the two support seats 16 and can evenly smooth the glue on the surface of the cardboard to achieve the effect of uniform glue application.

[0027] The working principle of the present utility model:

[0028] When the above structure is in specific use, first, the operator places the cardboard for corrugated box production on the conveyor 1. After being conveyed by the conveyor 1, when the cardboard is conveyed to the position where gluing is required, the electric push rod 4 drives the gluing box 3 to extend downward, so that multiple glue outlets 9 at the bottom of the gluing box 3 are attached to the surface of the cardboard. The glue inside the glue storage box 6 is transported to the inside of the gluing box 3 through the glue delivery hose 7 for storage, and the glue inside the gluing box 3 is injected onto the surface of the cardboard through multiple glue outlets 9, thereby realizing the gluing operation during the production of corrugated boxes;

[0029] And during the gluing process, after the cardboard is conveyed by the conveyor 1, the glue spreading roller 17 is attached to the surface of the cardboard. The glue spreading roller 17 rotates between two support seats 16, and can evenly smooth the glue on the surface of the cardboard, achieving the effect of uniform gluing;

[0030] In order to prevent the residual glue inside the glue outlet 9 from causing blockage at the glue outlet 9, during the process of the electric push rod 4 driving the gluing box 3 to extend downward, the glue outlet 9 contacts the surface of the cardboard, and extends upward inside the sleeve 8, so that the tension spring 15 is in a stretched state, and the dredging rod 12 at the bottom of the fixed block 10 extends outward from the glue outlet 9. The dredging rod 12 can dredge the glue outlet 9 and squeeze out the glue inside the glue outlet 9, thereby preventing the glue outlet 9 from being blocked due to glue solidification;

[0031] After the gluing box 3 extends upward under the action of the electric push rod 4, the tension spring 15 returns to its original position after being stretched, so that the dredging rod 12 can return to its initial position to ensure that the glue can be discharged;

[0032] It should be noted that in the present utility model, the conveyor 1 is an existing conveyor device, which is specifically composed of a bracket, a motor and a conveyor belt. The conveyor belt is driven by the motor to operate to realize the conveyance of the cardboard, and no further elaboration will be made here.

[0033] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
