Description

Technical Field

[0001] The present invention relates to the technical field of carton sealing and gluing equipment, and particularly to a carton sealing and gluing adhesive coating equipment. Background Art

[0002] After many products are produced, for the purpose of convenient transportation and protection, they need to be packaged and sealed with cartons. Most of the existing carton sealing equipment seals the cartons with tapes. The empty cartons are first loaded on the assembly line: the cartons are placed sideways (the openings face left and right), and the goods are pushed into the cartons by a push plate. Then the four foldable flaps on the left and right sides of the carton are folded up in sequence, and finally the tape is used to stick at the gap in the middle of the flaps to complete the sealing.

[0003] However, using tapes to seal cartons has the following disadvantages: The tape only adheres by the surface, and it is easy to crack due to edge warping or adhesive layer aging; and the tape contains non-degradable plastics, which is not environmentally friendly enough, and improper handling is likely to cause environmental pollution. Summary of the Invention

[0004] The present application provides a carton sealing and gluing adhesive coating equipment, which can solve the problems that using tapes to seal cartons is easy to crack due to edge warping or adhesive layer aging and is not environmentally friendly enough.

[0005] To solve the above technical problems, a carton sealing and gluing adhesive coating equipment is provided, including a conveyor belt device, and further including two first flap folding assemblies respectively arranged on the left and right sides of the conveyor belt device, and mounting frames for providing installation positions are arranged on both the left and right sides of the conveyor belt device. Each first flap folding assembly includes two first pressing members arranged corresponding to each other front and back. The first pressing members are rotatably arranged, their rotating shafts are all along the horizontal direction, and a first motor for driving their rotation is provided; A blocking rod moving in the left-right direction is arranged on each of the left and right sides of the conveyor belt device, and a first linear driving member for driving its movement is provided; A gluing mechanism is arranged on each of the left and right sides of the conveyor belt device. Each gluing mechanism includes two nozzles arranged corresponding to each other up and down and a second linear driving member for driving the nozzle to move back and forth; A second flap folding assembly is arranged on each of the left and right sides of the conveyor belt device. Each second flap folding assembly includes two second pressing members arranged one above the other. The second pressing members all move vertically, and a second driving member for driving their movement is provided.

[0006] In an embodiment, a first pulley is arranged at the rotating shaft of each first pressing member. In each first flap folding assembly, a first transmission belt is cross-wound between the two first pulleys, and the output shaft of the first motor is fixedly connected to one of the first pulleys.

[0007] In one embodiment, the first pressing member is L-shaped.

[0008] In one embodiment, the gear lever is located at the middle position in the vertical direction of the carton.

[0009] In one embodiment, the first linear driving member is a first air cylinder.

[0010] In one embodiment, each gluing mechanism further includes a connecting block, and the upper and lower nozzles are both fixedly arranged on the connecting block, and the second linear driving member is a push rod motor.

[0011] In one embodiment, the initial position of the nozzle is located at the front end of the carton in the seal, and the push rod motor is located at the front end of the nozzle.

[0012] In one embodiment, the two upper second pressing members are fixedly connected by a connecting rod, and the two lower second pressing members are also fixedly connected by a connecting rod. There are two second driving members, which are respectively used to drive the two upper second pressing members and the two lower second pressing members.

[0013] In one embodiment, the lower end of the second pressing member on the upper side branches out toward the front and rear sides, and the upper end of the second pressing member on the lower side branches out toward the front and rear sides.

[0014] In one embodiment, the second driving member is a second air cylinder.

[0015] In summary, in the present application, a carton sealing and gluing equipment has the following beneficial effects compared with the prior art: (1) First, the swing covers on the front and rear sides of the carton are folded up by the first folding cover assembly, then the folded swing covers are limited by the gear lever, and then the gluing mechanism applies glue to the upper and lower sides of the folded swing covers. Finally, the swing covers on the upper and lower sides of the carton are folded onto the applied glue by the second folding cover assembly to complete the sealing of the carton. The whole process is simple in operation and stable in effect; (2) Glue is used to bond and seal the carton, with lower consumable costs and more stable effects; (3) There is no tape mark after glue bonding, the surface is cleaner, and the glue does not cover the carton printing pattern, while the tape may cover part of the design; (4) The carton bonded with glue can be recycled and pulped as a whole, with higher material recyclability, while the tape needs to be torn off and sorted (the tape residue will reduce the recycling value of the carton); (5) Reduced plastic use: Water-based glue or starch-based glue is a degradable material, meeting the environmental protection trend, while tapes mostly contain plastic substrates (such as BOPP film) and are difficult to degrade.

[0018] For the convenience of understanding the present invention, the present invention will be described in more detail below in conjunction with the accompanying drawings and specific embodiments. The preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure content of the present invention more thorough and comprehensive.

[0019] It should be noted that unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not used to limit the present invention.

[0020] Please refer to Figure 1 、 Figure 2, A carton sealing and gluing equipment, including a conveyor belt device 3. There is a loading mechanism (not shown in the attached drawings of the specification) beside the conveyor belt device 3. The carton 1 is generally placed flat on the conveyor belt device 3 (with the opening facing left and right). The loading mechanism is used to put or push goods into the carton 1 from the left or right opening of the carton 1. The loading mechanism is prior art and will not be introduced in detail here.

[0021] Please refer to Figure 1 , Figure 2 , Figure 3 , There are four flaps 2 on each of the front, back, left, and right sides of the left and right sides of the carton 1. In the present invention, the direction in which the carton 1 advances on the conveyor belt device 3 is defined as the front, and the opposite direction is the back; in the horizontal plane, the directions perpendicular to the front-back direction are respectively the left and the right. Both sides of the conveyor belt device 3 are fixedly provided with mounting brackets 9 for providing mounting positions by welding. Two first flap folding assemblies are respectively arranged on the mounting brackets 9 on both sides of the conveyor belt device 3. Each first flap folding assembly includes two first pressing members 5 arranged correspondingly, one in front and one behind. The first pressing members 5 are all rotatably arranged, and their rotating shafts are all along the horizontal direction, and are provided with first motors 6 for driving their rotation. With this setting, the flaps 2 on the front and back sides of the carton 1 are folded up from the front and back sides by the rotation of the first pressing members 5.

[0022] Please refer to Figure 3 , In one implementation, a first belt pulley 7 is arranged at the rotating shaft of each first pressing member 5. The rotating shaft of the first pressing member 5 is hinged to the mounting bracket 9, and the hinged position is lower than the position of the carton 1. The first belt pulley 7 is fixedly connected to the rotating shaft of the first pressing member 5 by welding. In each first flap folding assembly, a first transmission belt 8 is cross-wound between the two first belt pulleys 7. There are two first motors 6, and their casings are respectively fixedly installed on the mounting brackets 9 on the left and right sides. The output shaft of each first motor 6 is fixedly connected to one of the first belt pulleys 7 for driving the two first pressing members 5 on the same side (in the same first flap folding assembly) to rotate towards each other, and folding up the flaps 2 on the front and back sides of the carton 1 from the front and back sides. With this setting, the two first pressing members 5 in the same first flap folding assembly are driven to rotate towards each other through the cross-drive setting method, and the structure is relatively reasonable. And compared with using four first motors 6 to drive the four first pressing members 5 to rotate, the number of first motors 6 is saved, that is, the cost is saved. Further, the first pressing member 5 is in an L shape, and with this setting, the structural effect is more reasonable.

[0023] Please refer to Figures 1-3 , Figure 6 , Figure 7, on each of the left and right sides of the conveyor belt device 3, there is a stop rod 10 that moves in the left-right direction, and a first linear drive member for driving its movement is provided, which is used to drive the two stop rods 10 to approach or move away from the cardboard box 1 on the left and right sides respectively. After the first flap assembly folds up the flaps 2 on the front and rear sides of the cardboard box 1, the first linear drive member drives the stop rod 10 to approach the cardboard box 1 and contact the two folded-up flaps 2 to limit them and prevent them from opening again. Further, the length direction of the stop rod 10 is along the front-rear direction. In one embodiment, the first linear drive member is a first cylinder 11, and there are two first cylinders 11. Their cylinder bodies are respectively fixedly installed on the mounting frames 9 on the left and right sides, and their telescopic rods are respectively fixedly connected to a stop rod 10 by welding. With this setting, because the cylinder is more suitable for driving this kind of single-direction linear push-pull action, and the cylinder has a fast response, low cost, and convenient maintenance. In one embodiment, preferably, the stop rod 10 is located at the middle position in the vertical direction of the cardboard box 1. With this setting, after the flaps 2 on the front and rear sides are folded up, the stop rod 10 can limit them from the middle position, and the effect is more stable.

[0024] Please refer to Figure 3 , Figure 7 , on each of the left and right sides of the conveyor belt device 3, there is a gluing mechanism. Each gluing mechanism includes two correspondingly arranged nozzles 13, one above the other, and a second linear drive member for driving the nozzles 13 to move back and forth. When the stop rod 10 restricts the flaps 2 on the front and rear sides of the cardboard box 1, the second linear drive member drives the two nozzles 13, one above and the other, to move, and apply glue to the flaps 2 (on the front and rear sides of the cardboard box 1) respectively on the upper and lower sides of the stop rod 10. Further, the nozzles 13 are connected to the glue supply system through a rubber hose 16. This is prior art and will not be introduced in detail here. The glue sprayed can be hot melt glue.

[0025] Please refer to Figure 3 , Figure 7 , in one embodiment, each gluing mechanism further includes a connecting block 15. The two nozzles 13, one above the other, are both fixedly arranged on the connecting block 15. The second linear drive member is a push rod motor 14 and there are two push rod motors 14. The two push rod motors 14 are respectively fixedly installed on the mounting frames 9 on the left and right sides, and are respectively used to drive the nozzles 13 on the left and right sides. With this setting, because the driving effect of the push rod motor 14 is relatively stable and can achieve precise control of the traveling speed, it is more suitable for this working condition: driving the nozzles 13 to travel slowly and stably for gluing. Further, the first cylinder 11 does not interfere with the traveling routes of the nozzles 13 and the connecting block 15. Preferably, the installation position of the first cylinder 11 is at the rear end of the cardboard box 1 in the front-rear direction.

[0026] Please refer to Figure 6, in one embodiment, preferably, the initial position of the nozzle 13 is located at the front end of the mouth-sealed carton 1, and the push rod motor 14 is located at the front end of the nozzle 13. With this arrangement, when the carton 1 arrives, the opened flap 2 will not interfere with the position of the nozzle 13 and the push rod motor 14.

[0027] Please refer to Figure 2 and Figure 3 , a second flap folding assembly is provided on each of the left and right sides of the conveyor belt device 3. Each second flap folding assembly includes two second pressing members 17, one above the other. The second pressing members 17 all move vertically, and a second driving member for driving their movement is provided. With this arrangement, after the gluing mechanism applies two upper and lower rows of glue on the front and rear flaps 2, the upper second pressing member 17 moves downward, and the lower second pressing member 17 moves upward to squeeze the left and right flaps 2 on the upper and lower sides onto the folded left and right flaps 2, so that the glue adheres between the two, completing the sealing of the left and right sides of the carton 1. Further, after the upper and lower flaps 2 of the carton 1 are closed, there is a certain gap between them, and the stop rod 10 is exactly in the gap between them, without affecting their closing. Further, when the upper and lower flaps 2 are closed on the folded left and right flaps 2, the stop rod 10 first retracts to its initial position, and the second pressing member 17 remains for a period of time and then retracts to its initial position (to ensure that the glue solidifies). And during this period, the front and rear flaps 2 have a tendency to expand outward after the stop rod 10 leaves, and can also fit more tightly with the upper and lower flaps 2, making the bonding effect more firm.

[0028] The first flap folding assembly, the stop rod 10, the gluing mechanism, and the second flap folding assembly are all located in front of the loading mechanism, that is, the above steps are carried out after loading is completed.

[0029] Please refer to Figure 2 and Figure 5 and Figure 6 , in one embodiment, the two upper second pressing members 17 are fixedly connected by a connecting rod 18 that bypasses above the carton 1, and the two lower second pressing members 17 are fixedly connected by a connecting rod 18 that bypasses above the carton 1 or below the conveyor belt. The fixed connection method can be welding. There are two second driving members, both of which are installed on the mounting frame 9 and are respectively used to drive the two upper second pressing members 17 and the two lower second pressing members 17. With this arrangement, the connecting rod 18 is used to achieve synchronous driving of the two upper second pressing members 17 and the two lower second pressing members 17, with stable effects and saving the number of second driving members used.

[0030] Please refer to Figure 2 and Figure 3, Figure 5 In one embodiment, the lower end of the second pressing member 17 located on the upper side bifurcates towards the front and rear sides, and the upper end of the second pressing member 17 located on the lower side bifurcates towards the front and rear sides. Preferably, the bifurcation is in the shape of a horn. With this arrangement, after the bifurcation, the stability of the pressing effect of the second pressing member 17 on the swing lid 2 can be improved.

[0031] Please refer to Figure 2 , Figure 3 In one embodiment, the second driving member is a second cylinder 19. With this arrangement, because the cylinder is more suitable for driving this single-direction linear push-pull action, and the cylinder has a fast response, low cost, and convenient maintenance.

[0032] The working process of the present invention is briefly described below: S1. After the carton 1 is loaded, it is conveyed by the conveyor belt device 3 to the sealing station (i.e., the location of the first flap assembly). S2. The first flap assemblies on the left and right sides both fold up the swing lids 2 on the front and rear sides of the carton 1 from the front and rear sides by the rotation of the first pressing member 5. S3. After the first flap assembly folds up the swing lids 2 on the front and rear sides of the carton 1, the first linear driving member drives the stop bar 10 to approach the carton 1 and contact the two folded swing lids 2 to limit them so that they will not open again. At the same time, the first pressing member 5 rotates back to the initial position. S4. After the stop bar 10 restricts the swing lids 2 on the front and rear sides of the carton 1, the second linear driving member drives the upper and lower nozzles 13 to move, and apply glue to the swing lids 2 (on the front and rear sides of the carton 1) on the upper and lower sides of the stop bar 10 respectively. The nozzle 13 discharges glue when moving forward and stops discharging glue when moving backward. S5. After the gluing mechanism applies two upper and lower rows of glue on the swing lids 2 on the front and rear sides, the second pressing member 17 located above moves downward, and the second pressing member 17 located below moves upward to squeeze the upper and lower swing lids 2 onto the left and right swing lids 2 that are folded up, so that the glue adheres between the two, completing the sealing of the left and right sides of the carton 1. S6. The stop bar 10 first retracts to the initial position, and the second pressing member 17 moves back to the initial position after waiting for a period of time. S7. The sealed carton 1 continues to move forward on the conveyor belt device 3, and repeats S1 - S7 when the next carton 1 to be sealed arrives.
