Description

Technical Field

[0001] The utility model relates to the technical field of gluing equipment, in particular to a gluing machine for the production of packaging bags. Background Art

[0002] A packaging bag refers to a bag used for packaging various articles, which facilitates the transportation of goods during the production and circulation process and is easy to store.

[0003] After retrieval, it is found that the Chinese patent with the application number 201821320108.9 discloses "a hot melt adhesive coating device for packaging bags, including a frame. The frame is provided with a gluing mechanism and a glue supply device. The gluing mechanism is at least composed of a mounting seat and a nozzle arranged below the mounting seat. The nozzle is provided with a glue delivery pipe communicated with the glue supply device; the lower end surface of the nozzle abuts against the surface of the packaging bag to be coated." However, when the above hot melt adhesive coating device for packaging bags coats the packaging bag, it uses the nozzle to apply glue on the packaging bag. However, when the nozzle moves away from the packaging bag, due to the adhesive force of the glue, the packaging bag is likely to move upward together with the nozzle when the nozzle leaves the packaging bag, resulting in the skew of the packaging bag or adhesion to the nozzle. Therefore, in order to solve such problems, a gluing machine for the production of packaging bags is proposed. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art, and a gluing machine for the production of packaging bags is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

An electric telescopic rod is installed at the bottom of the top plate. The end of the piston rod of the electric telescopic rod is installed with a gluing box. A plurality of circular grooves are opened at the bottom of the gluing box. A glue nozzle communicated with the gluing box is installed in the circular groove. Fixing plates are installed on both sides of the gluing box. Through holes are opened at the top of the fixing plates. A second sliding sleeve is installed in the through hole. A second sliding rod is slidably sleeved in the second sliding sleeve. The bottom end of the second sliding rod extends below the gluing box and is connected to a baffle. A second limit block is installed at the top end of the second sliding rod. A spring is installed between the second sliding sleeve and the baffle. The second sliding rod is located inside the inner ring of the spring. When the spring is in a natural state, the baffle is located below the gluing box.

[0007] Preferably, a glue tank is installed at the top of the top plate. Glue is loaded in the glue tank. The glue tank is communicated with a corrugated pipe. The corrugated pipe is communicated with the gluing box. A glue delivery pump is arranged in the corrugated pipe.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1: In the utility model, when the glue coating box moves upward, its spring begins to reset gradually. During the resetting process, its baffle always keeps pressing against the packaging bag under the action of the resetting force of the spring, so that when the glue coating box moves upward and breaks away from the contact with the packaging bag, its two baffles keep pressing against the packaging bag to firmly fix the packaging bag on the conveyor belt, thereby preventing the packaging bag from moving up with the glue coating box when the glue coating box moves upward due to the adhesion of the glue.

[0015] 2: In the utility model, when gluing the packaging bags, two baffles are first used to contact the packaging bags, so that the packaging bags to be glued can be first fixed on the conveyor belt, thereby improving the stability of the packaging bags during gluing and avoiding shaking and deviation of the packaging bags during gluing.

The top of the bottom plate 1 is connected to a top plate 4 through a support plate 3. An electric telescopic rod 5 is installed at the bottom of the top plate 4. The end of the piston rod of the electric telescopic rod 5 is installed with a glue application box 7. A plurality of circular grooves 21 are opened at the bottom of the glue application box 7. A glue nozzle 22 communicating with the glue application box 7 is installed in the circular groove 21. Fixed plates 14 are installed on both sides of the glue application box 7. Through holes are opened at the top of the fixed plates 14. A second sliding sleeve 16 is installed in the through holes. A second sliding rod 15 is slidably sleeved in the second sliding sleeve 16. The bottom end of the second sliding rod 15 extends below the glue application box 7 and is connected to a baffle 19. The top end of the second sliding rod 15 is installed with a second limiting block 17. A spring 18 is installed between the second sliding sleeve 16 and the baffle 19. The second sliding rod 15 is located inside the inner ring of the spring 18. When the spring 18 is in a natural state, the baffle 19 is located below the glue application box 7.

[0023] As a technical optimization solution of the present invention, a glue tank 8 is installed on the top of the top plate 4. Glue is loaded in the glue tank 8. The glue tank 8 is communicated with a bellows 9. The bellows 9 is communicated with the glue application box 7. A glue delivery pump 10 is arranged inside the bellows 9. The glue delivery pump 10 can facilitate the extraction of the glue in the glue tank 8 into the glue application box 7.

[0024] As a technical optimization solution of the present invention, a reinforcing block 6 is installed at the end of the piston rod of the electric telescopic rod 5. The reinforcing block 6 is fixedly connected to the top of the glue application box 7. The reinforcing block 6 can increase the connection strength between the end of the piston rod of the electric telescopic rod 5 and the glue application box 7, and improve the connection stability between the end of the piston rod of the electric telescopic rod 5 and the glue application box 7.

[0025] As a technical optimization solution of the utility model, a circular opening is provided at the top of the top plate 4. A first sliding sleeve 12 is installed in the circular opening. A first sliding rod 11 is slidably sleeved in the first sliding sleeve 12. The bottom end of the first sliding rod 11 is installed on the top of the glue application box 7. By the cooperation of the first sliding rod 11 and the first sliding sleeve 12, it can provide guidance for the up and down movement of the glue application box 7 and improve the stability of the up and down movement of the glue application box 7.

[0026] As a technical optimization solution of the utility model, a first limiting block 13 is installed at the top end of the first sliding rod 11, and the first limiting block 13 is located above the top plate 4.

[0027] As a technical optimization solution of the utility model, a conveyor belt 2 is installed on the top of the bottom plate 1, and the conveyor belt 2 is located directly below the glue application box 7.

[0028] As a technical optimization solution of the utility model, a rubber pad 20 is installed at the bottom of the baffle 19. The bottom end of the support plate 3 is installed on the top of the bottom plate 1, and the top end of the support plate 3 is installed on the side of the top plate 4. The rubber pad 20 can increase the friction between the baffle 19 and the packaging bag and improve the stability when the baffle 19 presses against the packaging bag.

[0029] When the utility model is in use, when it is necessary to apply glue to the packaging bag, first, place the packaging bag to be glued on the conveyor belt 2, and use the conveyor belt 2 to convey the packaging bag to be glued.

[0030] When the packaging bag to be glued is conveyed to directly below the glue application box 7 and stops. At this time, start the electric telescopic rod 5. The piston rod of the electric telescopic rod 5 pushes the glue application box 7 to move downward. When the glue application box 7 moves downward, it drives the two fixing plates 14 to move downward. When the two fixing plates 14 move downward, they can drive the two baffles 19 to move downward. When the spring 18 is in the natural state, the baffle 19 is located below the glue application box 7. Thus, when the glue application box 7 and the two baffles 19 move downward, the two baffles 19 can first contact the packaging bag on the conveyor belt 2. Use the downward movement of the two baffles 19 to fix the packaging bag on the conveyor belt 2. And as the piston rod of the electric telescopic rod 5 continues to extend, the glue application box 7 continues to move downward, and the baffle 19 and the fixing plate 14 can compress the spring 18 until the bottom of the glue application box 7 contacts the upper surface of the packaging bag to be glued and stops. Using the two baffles 19 to first contact the packaging bag can first fix the packaging bag to be glued on the conveyor belt 2, improve the stability of the packaging bag during gluing, and avoid the phenomenon of shaking and offset of the packaging bag during gluing.

[0031] At this time, start the glue delivery pump 10, the glue delivery pump 10 can extract the glue in the glue box 8 into the bellows 9, the glue entering the bellows 9 can enter the glue coating box 7 through the bellows 9, the glue entering the glue coating box 7 can be sprayed out through the glue nozzle 22, and then the glue is sprayed on the upper surface of the packaging bag that needs to be glued, thereby completing the gluing process of the packaging bag.

[0032] When the glue coating on the packaging bag is completed, the glue delivery pump 10 can be turned off, and the electric telescopic rod 5 can be started again. The piston rod of the electric telescopic rod 5 retracts to drive the glue coating box 7 to move up. When the glue coating box 7 moves up, its spring 18 begins to gradually reset, and during the resetting process of the spring 18, its baffle 19 always maintains pressure on the packaging bag under the action of the reset force of the spring 18, so that when the glue coating box 7 moves up and breaks away from the contact with the packaging bag, its two baffles 19 maintain pressure on the packaging bag to firmly fix the packaging bag on the conveyor belt 2, thereby avoiding the packaging bag following the glue coating box 7 to move up due to the adhesion of the glue. When the glue coating box 7 moves up to a height that the spring 18 can restore to its natural state, the two baffles 19 can follow the glue coating box 7 to move up and break away from the contact with the packaging bag, and the glue-coated packaging bag can be transported to the next station on the conveyor belt 2 for processing.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
