Description

Technical Field

[0001] The utility model belongs to the technical field of carton processing, and particularly relates to a glue coating device for carton processing with automatic loading and unloading. Background Art

[0002] Cartons are essential in today's life and production. Whether it is for loading and transporting goods or packaging for storing items, carton packaging is required, especially paper cartons, which are both environmentally friendly and convenient, and are the most commonly used outer packaging devices preferred by the public. The cardboard is made into a carton through die-cutting, indentation, and box gluing. Multiple steps in carton production usually require the use of glue, which is very important in the carton production process. The glue coating device for cartons came into being accordingly.

[0003] For example, a carton glue coating device disclosed in Patent Application No. CN201821429206.6 includes a base, a first movable baffle, and a second movable baffle. The two sides of the top of the base are fixed with horizontally arranged support platforms through brackets. The left and right ends of the support platform are respectively fixed with rollers through roller frames, and the shaft end of the roller near the left end of the support platform is connected with a driven wheel. The two groups of rollers are connected through a transmission belt. A first motor is installed on the top left side of the base. Starting the hydraulic cylinder can adjust the up and down movement of the rubber tube. When the rubber tube contacts the carton, the glue coating of the carton is realized, greatly improving the glue coating efficiency of the carton. The stirring paddle stirs the glue evenly to prevent stratification. Under the action of the pump body, the glue enters the rubber tube along the glue delivery pipe, and the glue seeps out along the rubber tube to complete the glue coating work of the carton. It has high practicability, greatly improves the use functionality of the carton glue coating device, ensures its use effect, and is suitable for wide promotion.

[0004] The prior art has realized automated glue coating production, but there are still certain deficiencies in the overall use process:

[0005] 1. In the process of carton production, some cartons only need to apply glue to part of the paper surface. Some of the prior art lacks a mechanism for adjusting and selecting the glue coating range and can only apply glue to the entire paper surface. Another part of the prior art sets a single glue coating head to apply glue along a path. This setting not only makes the equipment structure complex and is not conducive to expanding production, but also prolongs the processing time and reduces the processing efficiency.

[0006] 2. The glue coating devices of the prior art usually set up a glue tank to store glue. Glue has strong viscosity and is easy to adhere to the inner wall of the glue tank and cause problems such as caking and blockage. The glue tanks of the prior art often lack settings for scraping and stirring the inner wall of the glue tank. Content of the Utility Model

[0007] In order to overcome the deficiencies of the prior art, the utility model provides a glue coating device for carton processing with automatic loading and unloading. Through the settings of multiple glue discharging components and the like, the production personnel can control the device to only coat a part of the paper surface of the carton, improving the glue coating efficiency; and through the settings of the scraping and stirring components and the like, the device can automatically scrape and stir the glue in the glue tank during operation, effectively preventing problems such as adhesion, caking, and blockage.

[0008] In order to achieve the above object, the utility model provides the following technical solutions: A glue coating device for carton processing with automatic loading and unloading, including a base, on which a conveyor belt is drivingly arranged.

On the lower end face of the glue tank, a second scraper is rotatably arranged on the side away from the positioning component. On the lower end face of the glue tank, a plurality of glue discharging components are also fixedly arranged;

[0009] Each of the glue discharging components includes a fixed head fixedly arranged on the lower end face of the glue tank. Below the fixed head, a glue discharging head is rotatably arranged. Inside the glue discharging head, a detachable rubber ring and a metal wire filter are arranged. Below the metal wire filter, a glue discharging valve is arranged inside the glue discharging head.

[0010] Preferably, a plurality of first fixing blocks are fixedly arranged on the outer circumferential surface of the fixed head. On each of the first fixing blocks, a first groove for fixing a second electric push rod is arranged.

[0011] Preferably, a plurality of second fixing blocks are fixedly arranged on the outer circumferential surface of the glue discharging head. On each of the second fixing blocks, a first protrusion that can cooperate with the first groove is fixedly arranged.

[0012] Preferably, the scraping and stirring component includes a third electric push rod fixedly arranged above the glue tank. The output end of the third electric push rod extends into the glue tank and is connected with a first scraper. A plurality of openings are arranged on the first scraper. A plurality of openings are also fixedly arranged on the first scraper. On each of the stirring heads, a plurality of stirring blades are circumferentially arranged in an inclined manner.

[0013] Preferably, a detachable end cover is fixedly arranged on the upper end face of the glue tank. A feeding port is arranged on the end cover. At the center position of the upper end face of the end cover, a third electric push rod is also fixedly arranged.

[0014] Preferably, the positioning component includes a first electric push rod fixedly arranged on the base. The output end of the first electric push rod is fixedly arranged with a positioning plate that extends above the conveyor belt.

[0016] Preferably, an arc surface is provided on the lower end surface of the second scraper.

[0017] In summary, compared with the prior art, the beneficial effects of this solution are as follows:

[0018] (1) Through the arrangement of multiple glue discharging components and the like, the production personnel can control the area where the device applies glue to the paper surface by controlling the glue discharging valve in the glue discharging component.

Detailed implementation manners

[0031] In order to enable those skilled in the art of the present technology to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0032] Refer to the attached Figure 1 and the attached Figure 2 as well as the attached Figure 5 , a corrugated cardboard binding limiting mechanism includes a base 10. A drive motor 14 is fixedly arranged on one side of the base 10. A driving wheel 12 and a driven wheel 13 are also rotatably arranged in the base 10. A conveyor belt 11 is arranged between the driving wheel 12 and the driven wheel 13 in a transmission manner. The output end of the drive motor 14 is connected to the driving wheel 12. The above whole is the prior art, a belt conveyor line. In actual production, the conveyor belt 11 can continuously convey the cardboard boxes to be coated with glue into this device, realizing automatic loading and unloading.

[0033] Furthermore, refer to the attached Figure 1 and the attached Figure 4 , considering that the cardboard boxes on the belt conveyor line may be offset in position, two groups of positioning components are fixedly arranged on the base 10 on both sides of the conveyor belt 11. The positioning components can perform a positioning and adjustment function on the cardboard boxes on the conveyor belt 11, so that when the device applies glue to the cardboard boxes later, the cardboard boxes are located in the exact middle of the conveyor belt 11.

[0034] Furthermore, refer to the attached Figure 3 , the positioning component includes a first electric push rod 15 fixedly arranged on the base 10, and the output end of the first electric push rod 15 is connected with a positioning plate 16. When the cardboard boxes enter this device from the conveyor belt 11 on the side where the positioning components are arranged, the two groups of symmetrically arranged positioning components are activated. The output ends of the first electric push rods 15 on both sides extend to drive the positioning plates 16 thereon to move forward and push the cardboard boxes to the central position of the conveyor belt 11.

[0035] Furthermore, refer to the attached Figure 1 and the attached Figure 4 as well as the attached Figure 5, Between the driving wheel 12 and the driven wheel 13, two second electric push rods 17 are symmetrically arranged and fixed on the base 10. A cross beam 18 is connected between the output ends of the two second electric push rods 17, and a glue tank 19 is fixedly arranged on the cross beam 18. Production personnel can control the height of the cross beam by controlling the extension or retraction of the output ends of the two second electric push rods 17; a glue tank 19 is arranged on the cross beam, and below it is the glue discharging component of this device. The cross beam with adjustable height can meet the glue coating requirements of cartons with different thicknesses.

[0036] Further, refer to the appendix Figure 3 And the appendix Figure 4 , A end cover 20 is fixedly arranged on the glue tank 19, and a feeding port 21 is also fixedly arranged on the upper end face of the end cover 20. The function of the feeding port 21 is to add materials. Production personnel can add glue into the glue tank 19 through the feeding port 21; in case of equipment failure or when parts need to be replaced, production personnel can directly open the end cover 20 to operate on the inside of the glue tank.

[0037] Further, refer to the appendix Figure 5 , The appendix Figure 6 And the appendix Figure 7 , Above the conveyor belt 11, a plurality of glue discharging components are linearly arranged on the lower end face of the glue tank 19. Each glue discharging component corresponds to a glue discharging head 27, and a glue discharging valve 33 is fixedly arranged in each glue discharging head 27; on the side of the glue discharging component away from the positioning component, a second scraper 34 is also rotatably arranged on the lower end face of the glue tank 19. Considering that some cartons only need to be coated with glue on a partial area of the cardboard, when the cardboard passes below the glue discharging component, production personnel can control whether the device discharges glue to smear this part of the cardboard by controlling the glue discharging valve 33 in the glue discharging head 27; further, production personnel can also control the smearing effect of the entire automated production line by coding the glue discharging valve 33; when the carton after glue coating passes below the second scraper 34, the second scraper 34 can scrape and level the glue on the cardboard.

[0038] Further, refer to the appendix Figure 7 , On the side of the lower end face of the second scraper 34 close to the glue discharging component, a wire mesh filter 35 is arranged. On the one hand, the wire mesh filter 35 can effectively prevent the carton from being stuck by the second scraper 34; on the other hand, the wire mesh filter 35 can also improve the glue smearing effect, making it scrape and smear more evenly and flatly.

[0039] Further, refer to the appendix Figure 7 , The appendix Figure 8 And the appendix Figure 9, the glue discharging component includes a fixed head 26 fixedly arranged on the lower end face of the glue tank 19. A plurality of first fixing blocks 28 are fixedly arranged on the outer circumferential surface of the fixed head 26. Each first fixing block 28 is provided with a first groove 29. A glue discharging head 27 is rotatably arranged on the lower end face of the first fixing block 28. A plurality of second fixing blocks 30 are fixedly arranged on the outer circumferential surface of the glue discharging head 27. One end of each second fixing block 30 is provided with a first protrusion 31.

[0040] The glue discharging head 27 can rotate below the fixed head 26. When rotating, the first fixing block 28 and the second fixing block 30 can cooperate with each other. When the above-mentioned component rotates in place, the first groove 29 will be directly above the first protrusion 31. At this time, the production personnel only need to rotate the lower glue discharging head 27 to make the first groove 29 snap into the first protrusion 31 and cooperate with the first protrusion 31. At this time, the glue discharging head 27 is installed in place. If it needs to be disassembled, the production personnel only need to lift the glue discharging head 27 upward to make the first groove 29 disengage from the first protrusion 31 and reverse the glue discharging head 27 to rotate the second fixing block 30 out of the first fixing block 28 to remove the glue discharging head 27. The above settings enable the production personnel to quickly install and disassemble the component. When the glue discharging head 27 is damaged or blocked, the production personnel can quickly disassemble and assemble the glue discharging head 27 for maintenance or replacement.

[0041] Further, referring to Appendix Figure 7 , Appendix Figure 9 and Appendix Figure 10 , a rubber ring 32 is fixedly arranged inside the glue discharging head 27. A metal wire filter screen 35 is fixedly arranged inside the glue discharging head 27 below the rubber ring 32. A glue discharging valve 33 is also fixedly arranged inside the glue discharging head 27 below the metal wire filter screen 35. The rubber ring 32 can prevent leakage, enabling the glue discharging head 27 to have good sealing performance while being quickly disassembled and assembled; the metal wire filter screen 35 is arranged above the glue discharging valve 33, and the metal wire filter screen 35 plays a filtering role to prevent dust, dirt or glue lumps from entering the glue discharging valve 33 and causing blockage or damage problems.

[0042] Specifically, initially, the carton enters this device from the conveyor belt 11 on the side where the positioning component is set. The positioning components symmetrically arranged on both sides of the conveyor belt 11 extend the output ends, making the positioning plates 16 on the output ends synchronously approach the carton to be processed to perform positioning adjustment on the carton. After the adjustment is completed, the carton is in the middle position of the conveyor belt 11 and continues to move below the cross beam 18.

[0043] When applying glue, the glue discharging component on the lower end face of the glue tank 19 will discharge glue according to the settings of the production personnel and apply the glue to the set range of the carton passing below. Subsequently, the carton passes below the second scraper 34 behind the glue discharging component. The arc surface 37 below the second scraper 34 will scrape the just-dotted glue flat to evenly apply it to the area range of the carton where glue needs to be applied.

[0044] Subsequently, the conveyor belt 11 continues to push the glued carton forward and leaves the device.

[0045] Example 2:

[0046] Reference Attachment Figure 4 , Attachment Figure 5 And attached Figure 6 A third electric push rod 22 is fixedly provided on the upper end surface of the end cover 20, and the output end of the third electric push rod 22 passes through the end cover 20 and extends into the glue tank 19. The output end of the end cover 20 is connected to a first scraper 23, and a plurality of openings 24 are fixedly provided on the first scraper 23. A plurality of stirring heads 25 are also rotatably provided on the first scraper 23, and a plurality of stirring blades 36 are arranged obliquely on each stirring head 25.

[0047] As a further embodiment, the third electric push rod 22 can use its output end to drive the first scraper 23 on it to move back and forth within the glue tank, applying material to the sidewalls of the glue tank, reducing adhesion to the inner wall of the glue tank and thereby improving the utilization rate of the glue material. As the first scraper 23 moves up and down, the outer edge of the first scraper 23 scrapes the inner wall of the glue tank 19, and the glue passes through the opening 24. During this process, a large amount of glue flows through the stirring head 25 and passes through the stirring blades 36 thereon. Due to the inclined arrangement of the stirring blades 36, the stirring blades 36 are subjected to multiple circumferential tangential forces under the action of the fluid, causing the stirring head 25 to rotate as a whole. As the first scraper 23 moves up and down, the multiple stirring heads 25 on it rotate in different directions, ultimately achieving the effect of the entire mechanism scraping and stirring the glue simultaneously. The provision of the stirring head 25 significantly reduces the occurrence of glue solidification and caking, effectively preventing the problem of subsequent glue clogging in the glue discharge component.

[0048] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of the components as the criteria for distinction.
