Description

Technical Field

[0001] The present invention relates to the field of carton production, and particularly to a carton gluing machine for carton processing. Background Art

[0002] In the existing carton production process, the cardboard is usually die-cut first, and then slotted to form the sides of the carton. Finally, the carton is pasted by folding and pressing. During the folding and pasting process of the carton, the cardboard is adsorbed by a forming plate and placed in a forming machine to fold the cardboard into a carton. Therefore, the size of the forming plate needs to be the same as the size of the bottom of the carton. When the forming plate adsorbs the cardboard, only the middle area of the cardboard, that is, the bottom of the carton, is in the adsorbed state, and the four sides of the cardboard will droop along the pre-opened folding grooves. When the forming plate drives the cardboard to move, the four sides of the cardboard are likely to collide with the forming machine, resulting in the deviation and damage of the cardboard, affecting the subsequent forming. Summary of the Invention

[0003] In order to overcome the defect that in the process of adsorbing and transferring the cardboard in the prior art, the four sides of the cardboard are likely to collide with the forming machine, resulting in the deviation and damage of the cardboard and affecting the subsequent forming, the present invention provides a carton gluing machine for carton processing.

[0004] The technical solution is: a carton gluing machine for carton processing, including a gluing machine and a forming plate; the gluing machine is connected with the forming plate; it further includes a connecting frame, a communicating pipe and an air pump; the gluing machine is connected with the connecting frame; the forming plate is located inside the connecting frame; two communicating pipes are fixedly connected at each of the four corners of the connecting frame; four air pumps communicating with the communicating pipes are arranged on the connecting frame.

[0005] Further, it further includes a sliding block and a sliding shaft; one sliding shaft is fixedly connected at each of the four corners of the connecting frame; a sliding block is slidably connected to each sliding shaft; all the sliding blocks are fixedly connected with the forming plate.

[0006] Further, the sliding shaft is a chrome-plated optical shaft.

[0007] Further, it further includes a telescopic airbag and a telescopic hose; a telescopic airbag is fixedly connected to each sliding block; a telescopic hose is communicated between each telescopic airbag and the corresponding air pump.

[0008] Further, the telescopic airbag is arranged in an L shape.

[0009] Further, the air pump is a warm air pump.

[0010] Further, it further includes an electric telescopic rod; the gluing machine is connected with two electric telescopic rods; the two electric telescopic rods are jointly fixedly connected with the connecting frame; four L-shaped limiting parts are arranged on the connecting frame, the telescopic airbag is opposite to the L-shaped limiting part, and there is a distance for the cardboard to be inserted between the telescopic airbag and the L-shaped limiting part.

[0011] Further, it also includes a vision sensor; at least two vision sensors are connected to the forming plate.

[0012] Further, the forming plate is made of rubber material.

[0013] Further, the edges and corners of the forming plate are all chamfered.

[0014] The beneficial effects are as follows: The four sides of the cardboard are adsorbed through the connecting frame and the communicating pipe, preventing the four sides of the cardboard from drooping downward, which may cause the cardboard to easily collide with the conveying frame, the forming frame and the guiding plate during the moving process, resulting in the offset and damage of the cardboard side, and affecting the subsequent forming; The four sides of the formed carton are supported from the inside by the sliding blocks, preventing the four sides of the carton from tilting towards the middle. At the same time, the L-shaped telescopic airbag is used to bond and fix the bonding part, improving the fitting effect between the bonding part and the carton side; The electric telescopic rod drives the connecting frame to move downward, and then the L-shaped limiting part supports the upper part of the carton from the outside, avoiding the situation that when the sliding block moves to the upper part of the carton and squeezes and fits the bonding part of the upper part of the carton, the upper part of the carton is pressed and turned outwards and deformed; Through the hot air pump, the air entering the telescopic airbag is heated, and then the heat is transferred to the bonding part through the telescopic airbag, accelerating the solidification and forming of the applied glue, improving the operation continuity and reducing the glue solidification time.

Detailed implementation

[0017] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0018] Example 1: A carton gluing machine for carton processing, as Figures 1-7 shown, includes a gluing machine and a forming plate 4; a forming plate 4 is connected to the gluing machine, and an electric suction cup 4001 is arranged on the lower side of the forming plate 4; the gluing machine is composed of a support frame 1, a conveying frame 2, a first power unit 3, a second power unit 5, a receiving plate 6 and a forming frame 101; a conveying frame 2 and a first power unit 3 are fixedly connected to the support frame 1; the first power unit 3 is composed of an electric guide rail, a connecting plate and an electric push rod, the output end of the electric push rod is fixedly connected to the forming plate 4, and the electric guide rail drives the electric push rod to move horizontally through the connecting plate; a second power unit 5 is connected to the support frame 1; a receiving plate 6 is connected to the second power unit 5, and the structure of the second power unit 5 is the same as that of the first power unit 3; a forming frame 101 is fixedly connected to the support frame 1; It also includes a connecting frame 103, a connecting pipe 105 and an air pump 107; a connecting frame 103 is connected to the first power unit 3; the forming plate 4 is located inside the connecting frame 103; two connecting pipes 105 are fixedly connected to each of the four corners of the connecting frame 103; four air pumps 107 communicating with the connecting pipes 105 are arranged on the connecting frame 103.

[0019] It also includes a sliding block 104 and a sliding shaft 108; a sliding shaft 108 is fixedly connected to each of the four corners of the connecting frame 103; a sliding block 104 is slidably connected to each sliding shaft 108; all the sliding blocks 104 are fixedly connected to the forming plate 4.

[0020] The sliding shaft 108 is a chrome-plated optical shaft, which has the advantages of wear resistance, high precision and long service life, ensuring that the forming plate 4 can move up and down repeatedly and smoothly, and ensuring the normal operation of the equipment.

[0021] It also includes a telescopic airbag 106 and a telescopic hose 109; a telescopic airbag 106 is fixedly connected to each sliding block 104; a telescopic hose 109 is communicated between each telescopic airbag 106 and the corresponding air pump 107.

[0022] The telescopic airbag 106 is arranged in an L shape.

[0023] The air pump 107 is a warm air pump.

[0024] It further includes an electric telescopic rod 201; two electric telescopic rods 201 are fixedly connected to the connecting plate of the first power unit 3; the two electric telescopic rods 201 are jointly fixedly connected to the connecting frame 103; four L-shaped limiting parts 10301 are arranged on the connecting frame 103, the telescopic airbag 106 is opposite to the L-shaped limiting parts 10301, and there is a spacing for the cardboard 555 to be inserted between the telescopic airbag 106 and the L-shaped limiting parts 10301.

[0025] It further includes a vision sensor 202; two vision sensors 202 are fixedly connected to the bottom of the forming plate 4.

[0026] The working principle of the above embodiment is as follows: After the cardboard 555 with glue applied to all four bonding parts 55501 is conveyed above the support frame 1 by the conveying frame 2, the conveying frame 2 pauses, and at the same time, the first power unit 3 drives the forming plate 4 to move directly above the cardboard 555. Then, the first power unit 3 drives the forming plate 4 to descend, so that the electric suction cup 4001 on the lower side of the forming plate 4 contacts and adsorbs the cardboard 555. Then, the first power unit 3 transports the forming plate 4 and the cardboard 555 to directly above the forming frame 101. During this process, the second power unit 5 synchronously drives the receiving plate 6 to move upward, so that the upper surface of the receiving plate 6 is flush with the lower surface of the forming frame 101. Then, the first power unit 3 drives the forming plate 4 and the cardboard 555 to move downward into the forming frame 101. Then, the forming frame 101 forces the four sides of the cardboard 555 to fold inwards to form a shape, and the adjacent sides are adhesively fixed through the bonding parts 55501. Note that the forming frame 101 is a prior art, and the specific forming principle is not described here; after the cardboard 555 is folded and formed into a cardboard box, the second power unit 5 drives the receiving plate 6 to cooperate with the forming plate 4 to move downward, so that the cardboard box moves downward away from the forming frame 101. At the same time, the electric suction cup 4001 on the forming plate 4 is controlled to stop adsorbing, and then the first power unit 3 drives the forming plate 4 to rise and reset. Then, the second power unit 5 is controlled to drive the receiving plate 6 to convey the folded and formed cardboard box to the left for discharging.

[0027] Considering that, during the process that the electric suction cup 4001 on the forming plate 4 adsorbs the cardboard 555 and drives the cardboard 555 to move directly above the forming rack 101, only the middle area of the cardboard 555 is in the adsorbed state, and the four sides of the cardboard 555 will droop downward along the pre-opened folding grooves, resulting in easy collision between the cardboard 555 and the conveying rack 2 and the forming rack 101 during the movement, causing side deviation and damage of the cardboard 555, and affecting subsequent forming. Therefore, when the forming plate 4 descends and the electric suction cup 4001 contacts the cardboard 555, the air inlet on the lower side of the connecting pipe 105 synchronously contacts the side of the cardboard 555. When the electric suction cup 4001 adsorbs the middle of the cardboard 555, the air pump 107 is synchronously started to generate suction force in all the connecting pipes 105, adsorbing the four sides of the cardboard 555 to prevent the four sides of the cardboard 555 from drooping downward during the process that the forming plate 4 drives the cardboard 555 to transfer, affecting the movement of the forming plate 4 driving the cardboard 555 and subsequent forming. Note that when the cardboard 555 follows the forming plate 4 and moves down into the forming rack 101, the air pump 107 is turned off to release the adsorption effect of the connecting pipe 105 on the four sides of the cardboard 555, avoiding affecting the forming of the cardboard 555.

[0028] Furthermore, considering that when the cardboard 555 enters the forming rack 101 for forming, the four sides of the cardboard box (cardboard 555) will bend and incline towards the middle, resulting in the bonding part 55501 on the left side and the right side being unable to fit with the front side and the rear side. Therefore, as Figure 6 shown: During the process that the first power unit 3 drives the forming plate 4 and the cardboard 555 to move down into the forming rack 101, the forming plate 4 synchronously drives the sliding block 104 to move downward, and then through the sliding block 104, it presses against the four sides of the cardboard box from the inside to prevent the four sides of the cardboard box from inclining towards the middle. Then, the air pump 107 and the telescopic hose 109 are used to inflate the telescopic airbag 106, and then the telescopic airbag 106 expands outward towards the connecting frame 103. At this time, the outside of the cardboard box is limited by the forming rack 101, and the inside is squeezed by the telescopic airbag 106. Then, the bonding part 55501 is squeezed by the telescopic airbag 106 to improve the fitting effect between the bonding part 55501 and the side of the cardboard box. At the same time, after folding some cardboard 555 with longer sides, the first power unit 3 drives the forming plate 4 and the sliding block 104 to move upward and reset. Then, during the process that the sliding block 104 moves upward and resets, the bonding part 55501 is bonded and fixed by the sliding block 104 and the expanded telescopic airbag 106, without the need to set a longer sliding block 104 to match the length of the side of the cardboard box. And the telescopic airbag 106 is in an L shape and is adapted to the four angles of the cardboard box. Therefore, no matter which side of the four sides of the cardboard 555 the bonding part 55501 is located on, the telescopic airbag 106 can squeeze and fit the bonding part 55501 after expansion.

[0029] Further, considering that when the four sides of the carton are relatively long, the upper part of the carton will protrude upward from the forming rack 101, causing the telescopic airbag 106 to move to the upper part of the carton. When squeezing and fitting the bonding part 55501 of the upper part of the carton, the upper part of the carton will be pressed and fold outward, resulting in damage to the carton. Therefore, when folding and pressing the cardboard 555 with relatively long sides, the worker can control the electric telescopic rod 201 to drive the connecting frame 103 to move downward, and then use the L-shaped limiting part 10301 to support the upper part of the carton from the outside, preventing the sliding block 104 from moving to the upper part of the carton and causing the upper part of the carton to be pressed and fold outward when squeezing and fitting the bonding part 55501 of the upper part of the carton.

[0030] Further, the air pump 107 is a warm air pump. The air entering the sliding block 104 and the telescopic airbag 106 will be heated by the warm air pump to form hot air, causing the temperature of the sliding block 104 and the telescopic airbag 106 to rise. Then, the heat will be transferred to the bonding part 55501 through the sliding block 104 and the telescopic airbag 106, accelerating the solidification and forming of the glue, improving the operation continuity, and reducing the glue solidification time.

[0031] Based on the above technical effects, the present invention also has the following advantages: As Figure 4 shown: Two vision sensors 202 are fixedly connected to the bottom of the forming plate 4. When adsorbing the cardboard 555 through the forming plate 4, the length of the side of the cardboard 555 can be directly detected by the vision sensors 202. When it is detected that the side length of the cardboard 555 is relatively long, during the subsequent folding and forming process of the cardboard 555, the electric telescopic rod 201 will automatically drive the connecting frame 103 to move downward without manual intervention, reducing the labor intensity of the worker and improving the production efficiency.

[0032] As Figure 6 shown: The sliding shaft 108 is a chrome-plated optical shaft, which has the advantages of wear resistance, high precision, and long service life, ensuring that the forming plate 4 can move up and down repeatedly and stably, and ensuring the normal operation of the equipment.

[0033] Embodiment 2: On the basis of Embodiment 1, as Figure 1 and Figure 3 shown, the forming plate 4 is made of rubber material.

[0034] The corners of the forming plate 4 are all chamfered.

[0035] The working principle of the above embodiment is as follows: During the process of driving the cardboard 555 to move downward through the forming plate 4 and into the forming rack 101 for forming, by setting the forming plate 4 to be made of rubber material and chamfering its corners, the problem of scratching the cardboard 555 during the forming process is reduced, ensuring the quality of the carton.
