Description

Technical Field

[0001] The utility model relates to the field of packaging industry, in particular to a positioning jig for folding packaging boxes. Background Art

[0002] Packaging boxes are used to package products and also provide aesthetically pleasing packaging. They are now widely used in industries such as alcohol, tea, cigarettes, medicine, health products, cosmetics, toys, sporting goods, and other product packaging supporting industries. Packaging box processing has become an indispensable industry. During the production process, a completely flat cardboard sheet is folded into a box. This process generally requires an automatic box folding machine. However, traditional folding machines often suffer from long production lines and require multiple rolling mechanisms and push components for folding, resulting in high investment costs and prone to failure.

[0003] At present, the Chinese patent with authorization announcement number CN219312148U discloses an automatic folding machine for packaging boxes, including a folding machine body, which is composed of a folding area and a conveying area at the front end; rolling mechanisms are installed on both sides of the top of the folding machine body in the conveying area, and the rolling mechanism includes two mounting plate frames, the two mounting plate frames are close to each other and are rotatably connected to multiple first transmission wheels at the front end, and the multiple first transmission wheels are covered with a first transmission belt, and the first transmission belt is tilted downward from the front end of the conveying area to the rear end; the two mounting plate frames are rotatably connected to multiple second transmission wheels at the rear end of one side, and the multiple second transmission wheels are covered with a second conveyor belt, a support block is installed on the top of the mounting plate frame, and a pushing assembly is installed on the inner side of the support block. This device can press the folded packaging box through the rolling mechanism and the pushing assembly at the conveying area of ​​the folding machine body, which can effectively solve the problem that the cardboard bending part will bounce up, causing the cardboard packaging box to subsequently warp up, occupying too much space, and being inconvenient for subsequent sorting and storage.

[0004] The above-mentioned existing technical solutions have the following defects: folding requires the cooperation of multiple crushing mechanisms and pushing mechanisms, and there is no efficient folding module that can complete the task within the shortest distance. Utility Model Content

[0005] The purpose of the utility model is to provide a positioning jig for folding a packaging box, so as to solve the problems existing in the above-mentioned prior art.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] A positioning jig for folding packaging boxes, comprising a folding machine body, the folding machine body comprising a workbench and a vacuum conveyor belt, the vacuum conveyor belt being arranged on top of the workbench from right to left and used to convey materials from right to left, and positioning jigs being arranged on both sides of the vacuum conveyor belt, the positioning jig comprising a jig body, a folding limit mechanism, a front folding limit mechanism, and a rear folding limit mechanism;

[0008] The jig body is composed of a front support plate, a rear support plate and a top plate. A folding limit mechanism is provided on the right side of the bottom of the top plate. The folding limit mechanism includes a bending hook and a first guide wheel. The bending hook is fixedly mounted on the right side of the bottom of the top plate. The first guide wheel is fixedly mounted in the middle position of the bottom of the top plate. The folding limit mechanism is used to hook and fold a portion of the left side of the material.

[0009] The front folding limiting mechanism is fixedly mounted on the rear side of the front support plate, and the front folding limiting mechanism is composed of a first right oblique guide plate, a first left oblique guide plate and a second guide wheel;

[0010] The rear folding limiting mechanism is fixedly mounted on the front side of the rear support plate, and the rear folding limiting mechanism is composed of a second right oblique guide plate, a second left oblique guide plate and a third guide wheel.

[0011] By adopting the above technical solution, all the mechanisms required for folding are integrated into a whole. As long as the material is adsorbed on the vacuum conveyor belt and follows the vacuum conveyor belt through this whole, the folding can be completed. The bottom of the jig body is open for the material on the vacuum conveyor belt to pass through. In the process of passing the material, the folding limit mechanism at the bottom of the top plate will use a bending hook to hook up the left side of the material, and the first guide wheel set on the left side of the bending hook will crush the left side of the hooked material to complete the folding, and the front folding limit mechanism and the rear folding limit mechanism on both sides of the conveyor belt will complete the folding of the front and back sides of the material. First, the front and back sides of the material are tilted upward through the first right inclined guide plate from low to high, and then the second guide wheel and the third guide wheel are used to crush the front and back sides respectively, so that the front and back sides of the material are tilted toward the center line of the material, and finally the first left inclined guide plate from high to bottom is used to complete the folding of the material before leaving the jig.

[0012] In a further embodiment, the top left end of the bending hook is hinged and fixed to the bottom right side of the top plate, the bottom end of the spring is fixedly installed in the middle position of the right side of the bending hook, and the top end of the spring is fixedly connected to the bottom of the top plate.

[0013] By adopting the above technical solution, the bottom end of the bending hook is set closer to the conveyor belt. When material is conveyed by the conveyor belt, the front part that is not adsorbed by the vacuum conveyor belt will be hooked up by the bottom end of the bending hook. Since the material is adsorbed on the conveyor belt as a whole, it will not move. After the front side of the material is hooked up, as the conveyor belt continues to transport forward, the hooked front side will be crushed by the first guide wheel on the left side of the bending hook, and the folding of the front side of the material will be completely completed during the crushing process.

[0014] In a further embodiment, the front side of the first right oblique guide plate is fixedly mounted on the rear right end of the front support plate, and the first right oblique guide plate is used to fold the front side of the material upward.

[0015] By adopting the above technical solution, the first right inclined guide plate is set from low to high, with the right side lower and the left side higher. The overall curve is very smooth, which can ensure that the unadsorbed part of the front side of the material rises smoothly along the curve of the first right inclined guide plate.

[0016] In a further embodiment, the second guide wheel includes a bracket and a guide wheel body, the bracket is fixedly mounted on the front support plate, the bracket is located on the left side of the first right inclined guide plate, the guide wheel is rotatably mounted on the rear side of the bracket, and the guide wheel is used to fold a front part of the material.

[0017] By adopting the above technical solution, the second guide wheel is arranged on the left side of the first right inclined guide plate. Its function is similar to that of the first guide wheel, which is mainly to make the front side of the material fold further downward. However, at this time, the first guide wheel is not sufficient to completely fold the front part of the material. It mainly changes its angle to facilitate its entry into the first left inclined guide plate.

[0018] In a further embodiment, the first left oblique guide plate is fixedly mounted on the left end of the rear side of the front support plate, and the first left oblique guide plate is used to fold the front side of the material downward.

[0019] By adopting the above technical solution, the first left inclined guide plate is set from high to low to accommodate the folded part of the front side of the material. The material is transported forward by the conveyor belt, and the folded part of the material is gradually pressed to the lowest point. When it leaves the fixture, the entire material is folded.

[0020] In a further embodiment, a human-computer interaction system is provided on one side of the workbench, and the human-computer interaction system is used to adjust the running speed of the folding machine body in real time.

[0021] By adopting the above technical solution, the human-computer interaction system includes a touch screen, which displays various current operating data, such as production batches, folding volume per hour, etc. The running speed and adsorption strength of the vacuum conveyor belt can be adjusted, and the loading speed of the folding machine can also be adjusted through the human-computer interaction system.

[0022] In summary, the present invention has the following beneficial effects:

[0023] 1. Through the setting of the vacuum conveyor belt and the fixture body, the vacuum conveyor belt can firmly adsorb the material on the surface. At the same time, due to the porous design of the conveyor belt surface, the part of the material that needs to be folded will not be adsorbed by the vacuum device. In the process of the vacuum conveyor belt adsorbing the material and passing through the fixture body, with the help of the folding limit mechanism, front folding limit mechanism and rear folding limit mechanism set on the fixture body, it can greatly save time, shorten the length of the assembly line, and complete the material folding in a short distance.

[0024] 2. Through the setting of the folding limit mechanism, the left side of the material can be hooked up by the bending hook. The hooked part will pass under the bottom of the first guide wheel under the adsorption of the vacuum conveyor belt. Since the material itself is fixed, the rolling of the first guide wheel will not cause the material to move, and the folding effect is better, achieving the effect of rapid folding and fixing;

[0025] 3. Through the setting of the front folding limit mechanism and the rear folding limit mechanism, the material can be folded from the front and back sides respectively. First, the first right oblique guide plate and the second right oblique guide plate from low to high are used to fold the front and back sides of the material that are not adsorbed and fixed. The folded parts are subsequently crushed by the second guide wheel and the third guide wheel respectively, and further folded toward the middle position of the material. Finally, the first left oblique guide plate and the second left oblique guide plate from high to low are used to complete the folding effect while the material leaves the fixture body.

When the material is adsorbed by the vacuum conveyor belt 3 and passes through the jig body 4, the material will be completely folded.

[0034] Specific implementation process: The material can be firmly adsorbed on the conveyor belt 3 through the vacuum conveyor belt. A plurality of through holes are provided on the conveyor belt. The adsorption force is transmitted through the through holes. There is no adsorption force between the materials, and there is no adsorption force under the position where the materials are to be folded.

Since the bending hook 51 is hinged to the bottom of the top plate 43, when the bending hook 51 hooks the material, it will move with the movement of the material, but at the same time, a spring 53 fixedly connected to the bottom of the top plate 43 is provided at the middle position on the right side of the bending hook 51. Therefore, the spring 53 on the bending hook 51 will store energy during the movement, and when the left side of the material to be folded completes the initial After the first bending, the bending hook 51 is no longer driven forward, and is then pulled back by the spring 53 to return to its initial position. Then the first guide wheel 52 will crush the material to complete the folding, and the front and rear sides of the material with folding areas will contact the first right oblique guide plate 61 and the second right oblique guide plate 71 respectively. Since these two guide plates are set from low to high, the two sides of the folding area will be flipped upward. At the same time, the material will not be displaced due to the adsorption force of the vacuum conveyor belt 3 and the limiting influence of the first guide wheel 52. Only the front and rear sides of the material will be flipped up. Through the setting of the second guide wheel 63 and the third guide wheel 73, the material can be further folded inward, and the first left oblique guide plate 62 and the second left oblique guide plate 72 are both set from high to bottom. After entering the two guide plates on the left, the front and rear sides of the initially folded material will be folded as the guide plates are continuously lowered.
