Description

Technical Field

[0001] The invention belongs to the technical field of stacking food packaging bags, in particular to a stacking mechanism for producing food packaging bags. Background Art

[0002] Food packaging bags refer to film containers or composite material containers that are in direct contact with food and are used to hold and protect food. After the production of food packaging bags is completed, they need to be stacked together to facilitate subsequent processing of the food packaging bags, such as transportation and other operations.

[0003] The patent with announcement number CN218402995U discloses a stacking mechanism for producing food packaging bags, including a fixed plate, a conveyor belt and a guide rod. Support plates are fixedly installed at symmetrical positions on both sides of the upper surface of the fixed plate. A conveyor belt is arranged between the two support plates to convey the produced food packaging bags. The upper right ends of the two support plates are fixedly connected to the top of the guide plate. By using the conveyor belt, the electrostatic rod and the guide plate in coordination, the instant noodle packaging bags are sequentially and orderly conveyed to the right end of the conveyor belt. After the electrostatic rod above eliminates the static electricity, the instant noodle packaging bags slide onto the upper surface of the stacking plate through the guide plate. This process does not require too much manual operation. By providing a telescopic rod, the packaging bags are stacked more neatly, which improves the efficiency of packaging bag stacking. By providing a servo motor, it is convenient for the staff to take out the stacked packaging bags. The patented mechanism has a simple structure and is easy to use.

[0004] However, the above technical solution still has the following deficiencies in practical application:

[0005] When packaging bags are stored, the finished packaging bags are transported to the upper surface of the stacking board for storage, and then the telescopic plate is driven to move to the left to make the stacked packaging bags neat. However, in the process of the packaging bags falling onto the stacking board, the packaging bags may be deflected under the influence of air resistance, causing the packaging bags to fall on the stacking board at various angles. When the packaging bags are pushed by the telescopic plate, only one side of the packaging bags is subjected to force, and the four corners of multiple packaging bags will not be aligned, which will still affect the neatness of the stacking of the packaging bags and is not conducive to subsequent processing of the packaging bags. In addition, after the packaging bags are produced, the edges may have wrinkles. When the first packaging bag falls on the stacking board in a wrinkled or curled state, an uneven surface will be formed. When subsequent packaging bags continue to fall, they will fall on the uneven surface and be unevenly supported, thereby increasing additional deformation and wrinkles, thereby affecting the quality of the packaging bags.

[0006] To this end, the present invention provides a stacking mechanism for producing food packaging bags. Summary of the invention

[0044] Specifically, a food packaging bag refers to a film container or a composite material container that is in direct contact with food and is used to hold and protect food. After the production of the food packaging bag is completed, it needs to be stacked together to facilitate the use and storage of the food packaging bag. When the existing food packaging bag production stacking mechanism is used, the completed packaging bag is conveyed to the upper surface of the stacking plate for storage, and then the telescopic plate is driven to move to the left to make the stacked packaging bags neat. However, in the process of the packaging bag falling onto the stacking plate, the packaging bag may be deflected under the influence of air resistance, resulting in the packaging bag may When the packaging bags fall on the stacking board at various angles and are pushed by the telescopic board, only one side of the packaging bags is stressed, and the four corners of multiple packaging bags will not be aligned, which will affect the neatness of the stacking of the packaging bags and be detrimental to the subsequent processing of the packaging bags. In addition, the edges of the packaging bags may have wrinkles after they are produced, and when the first packaging bag falls on the stacking board in a wrinkled or curled state, an uneven surface will be formed. When the subsequent packaging bags continue to fall, they will fall on the uneven surface and be unevenly supported, thereby increasing additional deformation and wrinkles, which in turn affects the quality of the packaging bags;

[0045] Therefore, when the present embodiment is used, the placing table 4 is aligned with the terminal of the packaging bag production device. After the packaging bag production device has finished manufacturing the packaging bag, the packaging bag production device uses its own conveying mechanism to convey the packaging bag to the placing table 4, and makes the four sides of the packaging bag parallel to the four sides of the placing table 4, and the packaging bag is at the center of the placing table 4. The conveying mechanism is a function of the existing packaging bag production device, such as a conveyor belt, a push plate, a mechanical arm, etc., and there is no need to elaborate on it.

[0046] Then, according to the size of the packaging bag, the two-way threaded rod 16 and the two-way threaded rod 2 19 can be rotated under the action of the motor 3 18 and the motor 2 14, so as to adjust the spacing between the threaded blocks 17 on the left and right sides and the spacing between the two slide rails 2 44. Then, the motor 1 3 is used to drive the threaded rod 2 41 to rotate, so that the mounting frame 8 moves horizontally, so that the vacuum suction cup 15 is aligned with the four corners of the packaging bag, and then the vacuum suction cup 15 is lowered and contacted with the packaging bag under the action of the electric push rod 1 9. Then, under the action of the vacuum pump 12, the vacuum suction cup 15 adsorbs the packaging bag, and then the packaging bag is raised, and the packaging bag is driven to move to the left again, and the packaging bag is above the multiple limit plates 5.

[0047] Then, according to the size of the packaging bag, the motor eight 43 and the motor six 34 are started respectively, so that the two-way threaded rod six 32 and the two-way threaded rod four 33 are rotated, and the positions of the four limit plates 5 can be adjusted, so that the four limit plates 5 form a rectangle matching the size of the packaging bag, and the four corners of the packaging bag are aligned with the angles of the limit plates 5. At the same time, during the movement of the limit plates 5, the slide bar three 35 and the sleeve 36 form relative sliding, and then the motor seven 38 is started to drive the threaded rod one 39 to rotate, so that the multiple bearing plates 37 rise to the uppermost end at the same time, so that the bearing plates 37 are close to the bottom of the packaging bag;

[0048] Since the packaging bag may have wrinkles or curled edges after it is produced, the electric push rod 20 can be started to drive the mounting plate 22 to move, so that the pressing plate 1 29 and the pressing plate 2 30 are close to the edge of the packaging bag, and the edge of the packaging bag is between the pressing plates 1 29 and the pressing plates 2 30 on the upper and lower sides. In addition, according to the size of the packaging bag, multiple motors 5 27 are started to drive the two-way threaded rod 3 26 to rotate, so that the pressing plate 1 29 and the pressing plate 2 30 slide relative to each other, so that the length formed by the pressing plate 1 29 and the pressing plate 2 30 is the same as the side length of the packaging bag, and then the motor 4 24 is started to drive the two-way threaded rod 5 42 to rotate, so that the pressing plates 1 29 and the pressing plates 2 30 on the upper and lower sides are close to each other, forming a pressure relief on the edge of the packaging bag. The spring damper 28 is squeezed and deformed, and then the pressure plate 1 29 and the pressure plate 2 30 are driven again to move away from the edge of the packaging bag, so that the edge of the packaging bag can be smoothed. At the moment when the edge of the packaging bag is smoothed, the packaging bag is driven down again to make the bottom of the packaging bag contact with the load-bearing plate 37, and then the vacuum suction cup 15 releases the packaging bag, so that the packaging bag can be placed on the load-bearing plate 37, and the four corners of the packaging bag are in contact with the inner side of the limiting plate 5, so that the first packaging bag can be stored. Then, the above work is repeated to make multiple packaging bags overlap and be placed neatly. Moreover, since the packaging bags will become thicker as a whole after overlapping, the packaging bags that have been stored can be lowered by continuously driving the load-bearing plate 37, so that they are more convenient to place.

[0049] Therefore, by utilizing the anti-wrinkle storage mechanism, the storage space can be adjusted according to the size of the packaging bag, so that the edges of the packaging bag are restricted and the four corners are aligned, thereby improving the neatness of stacking, facilitating subsequent processing, and not easily becoming messy under the action of external forces; and, before the packaging bag is placed on the load-bearing plate 37, the positions of the pressing plates 1 29 and 2 30 can be adjusted according to the side length of the packaging bag to smooth the edges of the packaging bag at once to make its surface flat, thereby avoiding the situation where the neatness of stacking is affected by wrinkles on the edges of the packaging bag, and, after smoothing, the packaging bag can be immediately placed on the load-bearing plate 37, which helps to maintain this flat state, reduces the possibility of the packaging bag reforming wrinkles due to its own gravity or external pressure, and improves the neatness of storage.

[0050] In this embodiment, Figure 1 and Figure 6 As shown, a pressure sensor 40 is provided at the lower end of the load-bearing plate 37 on one side, and an indicator light 45 is provided at one side of the left end of the frame 2. The pressure sensor 40 and the indicator light 45 are both electrically connected to the control device;

[0051] Specifically, the pressure sensor 40 is set according to the number of packaging bags that need to be stored at one time. When the packaging bags are placed on the load-bearing plate 37, the pressure sensor 40 will detect pressure. When the number of packaging bags increases, the value detected by the pressure sensor 40 is gradually increasing. When the pressure sensor 40 reaches the set value, it means that a sufficient number of packaging bags have been stored. At this time, the indicator light 45 lights up to remind the staff that the packaging bags have been stored and the packaging bags can be taken out, thereby effectively reminding the staff that the set number of packaging bags have been stored.

[0052] Working principle: according to the number of packaging bags that need to be stored at one time, the pressure sensor 40 is set. When the packaging bag is placed on the load-bearing plate 37, the pressure sensor 40 will detect the pressure. When the number of packaging bags increases, the value detected by the pressure sensor 40 is gradually increasing. When the pressure sensor 40 reaches the set value, it means that a sufficient number of packaging bags have been stored. At this time, the indicator light 45 lights up to remind the staff that the packaging bags have been stored and the packaging bags can be taken out, thereby effectively reminding the staff that the set number of packaging bags have been stored, so that the placement table 4 is aligned with the terminal of the packaging bag production device. After the packaging bag production device has manufactured the packaging bag, the packaging bag production device uses its own conveying mechanism to convey the packaging bag to the placement table 4, and makes the four sides of the packaging bag parallel to the four sides of the placement table 4, and the packaging bag is at the center of the placement table 4. The conveying mechanism is a function of the existing packaging bag production device, such as a conveyor belt, a push plate, a mechanical arm, etc., and there is no need to elaborate on it; then according to the size of the packaging bag, the bidirectional threaded rod 1 16 and the bidirectional threaded rod 1 16 can be driven by the motor 3 18 and the motor 2 14. The threaded rod 19 is rotated to adjust the distance between the threaded blocks 17 on the left and right sides and the distance between the two slide rails 44. Then, the motor 3 is used to drive the threaded rod 41 to rotate, so that the mounting frame 8 moves horizontally, so that the vacuum suction cup 15 is aligned with the four corners of the packaging bag. Then, under the action of the electric push rod 9, the vacuum suction cup 15 is lowered and contacts the packaging bag. Then, under the action of the vacuum pump 12, the vacuum suction cup 15 absorbs the packaging bag, and then the packaging bag is raised, and the packaging bag is driven to move to the left again, and the packaging bag is above the multiple limit plates 5. Then, according to According to the size of the packaging bag, the motor eight 43 and the motor six 34 are started respectively to rotate the two-way threaded rod six 32 and the two-way threaded rod four 33, so that the positions of the four limit plates 5 can be adjusted, so that the four limit plates 5 form a rectangle matching the size of the packaging bag, and the four corners of the packaging bag are aligned with the angles of the limit plates 5. At the same time, during the movement of the limit plates 5, the slide bar three 35 and the sleeve 36 form relative sliding, and then the motor seven 38 is started to drive the threaded rod one 39 to rotate, so that the multiple bearing plates 37 rise to the uppermost end at the same time, so that the bearing plates 37 are close to the bottom of the packaging bag;Since the packaging bag may have wrinkles or curled edges after being produced, the electric push rod 20 can be started to drive the mounting plate 22 to move so that the pressing plate 1 29 and the pressing plate 2 30 are close to the edge of the packaging bag, and the edge of the packaging bag is between the pressing plate 1 29 and the pressing plate 2 30 on the upper and lower sides. In addition, according to the size of the packaging bag, multiple motors 5 27 are started to drive the bidirectional threaded rod 3 26 to rotate so that the pressing plate 1 29 and the pressing plate 2 30 slide relative to each other, so that the length formed by the pressing plate 1 29 and the pressing plate 2 30 is the same as the side length of the packaging bag. Then, the motor 4 24 is started to drive the bidirectional threaded rod 5 42 to rotate, so that the pressing plates 1 29 and 2 30 on the upper and lower sides are close to each other, squeezing the edge of the packaging bag, and the spring damper 28 is deformed. Then, the pressing plates 1 29 and 2 30 are driven away from the edge of the packaging bag again, so that the edge of the packaging bag can be smoothed. At the moment when the edge of the packaging bag is smoothed, the packaging bag is driven down again, so that the bottom of the packaging bag contacts the load-bearing plate 37, and then the vacuum suction cup 15 releases the packaging bag, so that the packaging bag can be placed on the load-bearing plate 37, and the packaging bag is The four corners of the bag are fitted with the inner side of the limiting plate 5 to realize the storage of the first packaging bag, and then the above work is repeated to make multiple packaging bags overlap and place neatly. Moreover, since the packaging bags become thicker as a whole after overlapping, the packaging bags that have been stored can be lowered by continuously driving the load-bearing plate 37 to make it easier to place. Thus, the anti-wrinkle storage mechanism can be used to adjust the storage space according to the size of the packaging bag, so that the edge of the packaging bag is limited and the four corners are aligned, thereby improving the neatness of stacking and facilitating subsequent processing. It is not easy to become messy under the action of external force; and before the packaging bag is placed on the load-bearing plate 37, the positions of the first pressing plate 29 and the second pressing plate 30 can be adjusted according to the side length of the packaging bag to smooth the edge of the packaging bag and make its surface flat, avoiding the situation where the packaging bag edge has wrinkles that affect the stacking neatness, and after smoothing, the packaging bag can be immediately placed on the load-bearing plate 37, which helps to maintain this flat state, reduce the possibility of the packaging bag re-forming wrinkles due to its own gravity or external pressure, and improve the neatness of storage. ;
