Description

TECHNICAL FIELD

[0001] The utility model belongs to wine box packaging technical field, concretely relates to a bottom box loading positioning mechanism. BACKGROUND

[0002] In the modern wine box production process, the application of automatic gluing process is increasingly widespread to improve production efficiency and product quality. However, the current wine box packaging paper gluing equipment has some problems to be solved in actual operation.

[0003] At present, the gluing process of wine box packaging paper usually places a pile of packaging paper at the loading station, and then the packaging paper is sucked one by one to the gluing device by the movable suction cup device for gluing. Although this process realizes automation to some extent, it is found in actual operation that the packaging paper is prone to deviation and falling off at the loading station. This not only affects the suction accuracy of the suction cup device, causes part of the packaging paper to be unable to be accurately transmitted to the gluing position, reduces the production efficiency, but also may cause mispositioning of the subsequent gluing process, affect the appearance and sealing of the wine box, and further reduce the overall quality of the product.

[0004] In addition, due to the randomness of the deviation and falling off of the packaging paper, the production process is unstable, which increases the risk of equipment failure and maintenance cost. Under the background of fierce competition in the wine box production industry and increasingly strict requirements for product quality, the existing gluing process has been difficult to meet the efficient, precise and stable production demand. Therefore, it is urgent to design a positioning structure capable of limiting the packaging paper in front, back, left and right directions to overcome the shortcomings in the prior art and improve the automation level and product quality of the wine box gluing process. SUMMARY

[0005] Therefore, the utility model provides a bottom box loading positioning mechanism to solve the problem that the packaging paper is prone to deviation and falling off at the loading station in the prior art.

[0006] The technical scheme adopted by the utility model is as follows:

[0007] A bottom box loading positioning mechanism, comprising a vertical plate, one end of the vertical plate is provided with a support plate in sliding connection therewith, the support plate is driven by a driving device to move along the height direction of the vertical plate, and the support plate is used to place packaging paper; one side of the vertical plate is provided with two first vertical columns, the two first vertical columns are spaced apart along the length direction of the vertical plate, a support is arranged at the top of each first vertical column, one end of the support is provided with a first baffle, and the first baffle contacts one end in the width direction of the packaging paper; both ends of the vertical plate in the length direction are respectively provided with a second baffle, and the two second baffles respectively contact both ends in the length direction of the packaging paper.

[0008] The technical scheme is characterized in that, in the wine box production process, accurate positioning and limiting of the packaging paper is a key link to ensure the quality of the glue coating. The limiting structure involved in the scheme is mainly applied to the positioning and fixing of the paper sheet after the bottom box of the wine box is unfolded before the glue coating. In actual operation, first, a stack of packaging papers after stacking and arrangement is placed stably on the support plate. At this time, the two first baffles are respectively located on the side of the packaging paper away from the vertical plate, effectively limiting one end of the packaging paper in the width direction, preventing the end from deviating in the width direction. At the same time, the two second baffles are in close contact with the two ends of the packaging paper in the length direction, limiting the length direction of the packaging paper, ensuring that the packaging paper will not slide or dislocate in the length direction. In addition, the vertical plate itself forms a stable support and limiting for the end of the packaging paper close to it, and together with the first baffle and the second baffle, it forms a stable limiting frame to realize the overall limitation of the four sides of the packaging paper. This limiting method can effectively prevent the packaging paper from deviating or falling off due to external force during the glue coating process. Through this method, not only the efficiency of the glue coating is improved, but also the design of the limiting structure is simple and reasonable, easy to maintain and adjust, and provides strong support for the automatic production of the wine box.

[0009] Preferably, a first strip-shaped hole is provided through the support, the first strip-shaped hole is perpendicular to the vertical plate, a first screw hole is provided at the top of the first vertical column, a first bolt is screwed into the first screw hole, the first bolt is located in the first strip-shaped hole, and a first nut is provided at the top of the first bolt.

[0010] The technical scheme is characterized in that, in the technical scheme, in order to realize the stable connection of the support and the first column and facilitate adjustment, a detachable connecting structure is specially designed. Specifically, a first slot is provided through the support, and the slot is arranged in a vertical direction with the vertical plate. A first screw hole is provided at the top of the first column, and a first bolt is screwed in the first screw hole. The first bolt passes through the first slot of the support, and by screwing the first bolt, it gradually moves downward until the first nut presses the first gasket, thereby firmly fixing the support on the first column. This design not only realizes the reliable connection of the support and the first column, but also provides flexibility in adjusting the position of the support. By providing the first slot, the worker can flexibly adjust the position of the support on the first column according to the actual size requirements of the paper sheet. When adjusting the position of the support, simply loosen the first nut, move the support to the appropriate position along the slot, and then tighten the first nut again to complete the adjustment of the position of the support. This adjustable connection method makes the limiting structure adaptable to packaging paper of different sizes, improving the versatility and flexibility of the equipment. In addition, to enhance the stability and reliability of the connection, a first gasket is provided on the first bolt, and the first gasket is located between the support and the first nut. When the first nut gradually presses the first gasket, the gasket can evenly transmit the pressure, preventing deformation or damage of the support due to uneven local stress, thereby prolonging the service life of the equipment. This detachable connection design not only facilitates the installation, disassembly and maintenance of the equipment, but also allows quick adjustment of the position of the support according to actual production needs to adapt to packaging paper of different specifications.

[0011] Preferably, a second column is provided between each of the first columns and the vertical plate, and an elastic sheet is provided at the top of each second column, extending above the packaging paper. A second slot is provided through the elastic sheet, a second screw hole is provided at the top of the second column, a second bolt is screwed into the second screw hole, the second bolt is located in the second slot, and a second nut is provided at the top of the second bolt. A second gasket is provided on the second bolt, and the second gasket is located between the elastic sheet and the second nut.

[0012] The technical scheme needs to be explained that, in the automatic packaging production line, in order to solve the overlapping problem of the suction cup when sucking the paper sheet, the second column is arranged between each first column and the vertical plate, and the elastic sheet extending above the packaging paper is arranged on the top of the second column. The elastic sheet is fixed by the second bolt, the second gasket and the second nut, and a second slot is arranged on the elastic sheet to facilitate the adjustment of the position. When the suction cup sucks the paper sheet, the overlapping paper sheet is shaken off by the upward, downward and upward movement, and the elastic sheet blocks the paper sheet and generates a rebound force when the paper sheet moves downward, so as to shake off the bottom paper sheet and avoid adhesion and overlapping, thereby improving the production efficiency and product quality. Specifically, the elastic sheet has good elasticity and can play an important role when the suction cup sucks the paper sheet. After the suction cup sucks the paper sheet, the paper sheet is driven to move upward, downward and upward. This special movement mode can effectively shake off the overlapping paper sheet and ensure that only one paper sheet is transmitted each time. In order to realize the adjustability and stability of the elastic sheet, a second slot is arranged on the elastic sheet, and a second screw hole is arranged on the top of the second column, and a second bolt is screwed in the second screw hole. The second bolt passes through the second slot on the elastic sheet, and by screwing the second bolt, it gradually moves downward until the second nut presses the elastic sheet tightly, so as to firmly fix the elastic sheet on the second column. In addition, the second bolt is further sleeved with the second gasket, and the second gasket is located between the elastic sheet and the second nut. This design not only enhances the stability of the connection, but also prevents the elastic sheet from deforming or being damaged due to uneven local stress. Through this ingenious design of the elastic sheet, not only the problem of overlapping paper sheet is solved, but also the adaptability of the equipment to different paper sheets is enhanced, the failure and the defective rate in the production process are reduced, and a more reliable and efficient solution for the automatic production of wine box packaging is provided.

[0013] Preferably, a mounting slot is arranged in the middle of the vertical plate, a moving seat in sliding connection with the mounting slot is arranged on the support plate, the driving device comprises a lead screw and the moving seat, the two ends of the lead screw are rotatably connected with the two ends of the mounting slot, and the moving seat is in threaded connection with the lead screw. The lead screw is driven by the motor.

[0014] In the technical scheme, it needs to be explained that, in the automatic packaging production line, in order to realize the accurate up and down movement of the packaging paper, a through mounting slot is arranged in the middle of the vertical plate, and a moving seat in sliding connection with the mounting slot is arranged on the support plate. The driving device comprises a lead screw and the moving seat, the two ends of the lead screw are rotatably connected with the two ends of the mounting slot, the moving seat is in threaded connection with the lead screw, and the lead screw is driven by the motor. When working, the motor drives the lead screw to rotate, so that the moving seat moves along the height direction of the vertical plate, thereby adjusting the up and down position of the support plate. This structure utilizes the accuracy and stability of the lead screw transmission to ensure the accurate position of the packaging paper, adapt to different height requirements, and improve the universality and reliability of the equipment, which is a key innovation for automatic production.

[0015] Therefore, the packaging paper can be prevented from being offset or falling off due to external force in the gluing process, and the gluing efficiency is improved.

[0017] 2. In the utility model, in order to enhance the stability and reliability of the connection, a first gasket is further sleeved on the first bolt, and the first gasket is located between the support and the first nut. When the first nut gradually presses the first gasket, the gasket can uniformly transmit the pressure, preventing the support from being deformed or damaged due to uneven local stress, thereby prolonging the service life of the equipment. The detachable connection design not only facilitates the installation, disassembly and maintenance of the equipment, but also can quickly adjust the position of the support according to the actual production needs to adapt to packaging paper of different specifications.

The accuracy and stability of the transmission of the lead screw 20 are utilized, the position of the wrapping paper 3 is ensured to be accurate, different height requirements can be adapted, and the universality and reliability of the equipment are improved.

[0041] III. Anti-overlapping mechanism of paper sheets

[0042] When the suction cup sucks the wrapping paper 3 upward, the situation of overlapping of two paper sheets may occur. In order to solve this problem, the second vertical column 7 is arranged between each first vertical column 4 and the vertical plate 1, and the elastic sheet 8 extending to the upper side of the wrapping paper 3 is arranged at the top of the second vertical column 7. The elastic sheet 8 is fixed by the second bolt 17, the second gasket 18 and the second nut, and a second slot 15 is arranged on the elastic sheet 8, so as to facilitate the adjustment of the position. When the suction cup sucks the paper sheet, the paper sheet will be driven to move upward, downward and upward again. This special movement mode can effectively shake off the overlapping paper sheets, and ensure that only one paper sheet is transmitted each time. When the suction cup drives the paper sheet to move downward, the elastic sheet 8 will block the paper sheet and generate a certain rebound force on the paper sheet, so that the bottom paper sheet is shaken off, further avoiding the adhesion and overlapping of the paper sheets, and improving the production efficiency and product quality.
