Description

Technical Field

[0001] The utility model relates to the technical field of carton processing, and specifically relates to a finished carton stacking rack. Background Technique

[0002] During production and processing, cartons are often in the form of flat cardboard for transportation and stacking, and then they can be shaped and fixed to hold goods. There are various forms of existing carton stacking racks.

[0003] For example, the patent with the publication number CN216103604U discloses a finished carton stacking rack for carton processing, including a bearing mechanism, a protection mechanism and a reinforcement mechanism. The bearing mechanism includes a bottom plate, the lower end of the bottom plate is fixedly installed with supporting feet, and the lower end of the supporting feet is fixedly installed with foot pads. The protection mechanism includes a right side plate, the left end of the upper end of the bottom plate is fixedly installed with a left side plate, the rear end of the upper end of the bottom plate is fixedly installed with a rear side plate, the inner ends of the right side plate and the left side plate are fixedly installed with a support plate, and the reinforcement mechanism includes a movable groove, and a limiting plate is movably installed inside the movable groove.

[0004] Through the above settings, the existing finished carton stacking rack for carton processing can, when a carton is placed down, use the limiting plate to rise under pressure to limit the carton, avoid its slipping during stacking, effectively improve the stacking stability, and at the same time can also avoid the carton from tilting and collapsing during storage, further improving the storage stability. However, the existing finished carton stacking rack for carton processing in the prior art has the following defects during operation:

[0005] When stacking finished cartons on the shelf in the above device, the carton is moved to the upper end of the support plate. When the carton is placed down, the carton contacts the vertical plate, and the vertical plate is pressed to squeeze the sliding plate backward, and at the same time the limiting plate is lifted upward, so as to limit the carton through the limiting plate. However, in this process, the carton needs to be directly above the vertical plate to achieve this, so the required conditions are too harsh. Moreover, when stacking cartons of different specifications, the center of gravity of the carton cannot be kept at the center of gravity of the support plate, which will lead to the overall collapse of the device. Summary of the Utility Model

[0006] The utility model aims to provide a finished carton stacking rack, which is mainly used to solve the technical problems that the conditions for stacking cartons in the prior art are too harsh and the center of gravity of the carton is unstable when stacking cartons of different specifications.

[0007] To solve the above technical problems, the utility model provides the following technical solutions:

[0008] A finished product carton stacking rack, including a housing fixedly connected to the top of a bottom plate. A plurality of rectangular blocks are symmetrically and fixedly connected to the inner side wall of the housing. A support plate is slidably connected to the inner side wall of the housing above the rectangular blocks. A cavity is formed inside the rectangular block. A pneumatic component is fixedly connected to the top of the rectangular block. A sleeve is fixedly connected to the inner side wall of the cavity. A telescopic component is slidably connected to the inner side wall of the sleeve. A rectangular chute is formed on the top of the support plate. An installation hole is formed on the side wall of the support plate and is communicated with the rectangular chute. A clamping component is rotatably connected to the inner side wall of the installation hole.

[0009] The working principle and beneficial effects of the present utility model:

[0010] 1. Working principle: When the device is in use, first place the carton on the top of the support plate. Under the action of the gravity of the carton, the support plate will slide downward along the inner side wall of the housing. During this process, the pneumatic component works, so that the pneumatic component pumps air into the cavity. Then the air pressure inside the cavity continuously increases. Then, due to the relatively large air pressure inside the cavity, the telescopic component works, and then the telescopic component is used to limit the stacked cartons. Then, by adjusting the clamping component, the stacked cartons are moved to the center of the support plate through the clamping component, and the stacked cartons are reinforced.

[0011] 2. Beneficial effects:

[0012] In the prior art, by setting a limiting plate, when the carton is placed, it will be pressed upward to limit the carton, avoiding the technical problem of slipping during stacking. However, the prior art has the technical problems that the conditions for stacking cartons are too harsh and the center of gravity of the cartons is unstable when stacking cartons of different specifications. In this solution, through the pneumatic component provided, the air pressure inside the cavity continuously increases during the stacking process of the cartons. Then, due to the relatively large air pressure inside the cavity, the telescopic component works, so as to limit the stacked cartons. Then, by adjusting the clamping component, the stacked cartons are moved to the center of the support plate through the clamping component, and the stacked cartons are reinforced.

[0013] Preferably: The pneumatic component includes an airbag fixedly connected to the top of the rectangular block. The top of the airbag is fixedly connected to the bottom of the support plate. A round hole is formed through the top of the rectangular block at the position of the airbag, and the airbag is communicated with the cavity. When stacking the cartons, first place the cartons on the top of the support plate. Under the action of the gravity of the cartons, the support plate will slide downward along the inner side wall of the housing. During this process, the airbag is compressed, and the gas inside the airbag will enter the cavity through the round hole. Then, as the airbag is compressed, the air pressure inside the cavity continuously increases. Then, due to the relatively large air pressure inside the cavity, the telescopic component works, so as to limit the stacked cartons.

[0014] Preferably, the telescopic assembly includes a piston slidably connected to the inner side wall of the sleeve. A telescopic rod is fixedly connected to the top of the piston. A through hole is formed in the outer side wall of the lower end of the sleeve, and the sleeve communicates with the cavity. When the air pressure inside the cavity continuously increases, the greater air pressure enters the inside of the sleeve through the through hole. Then, under the action of the piston, the piston drives the telescopic rod to move upward along the inner side wall of the sleeve, thereby using the telescopic rod to limit the stacked cartons and prevent the cartons from collapsing from the front of the device.

[0015] Preferably, a spring is fixedly connected to the top of the rectangular block, and the upper end of the spring is fixedly connected to the bottom of the support plate. When the carton is removed, under the action of the compressed spring, the support plate moves upward along the inner side wall of the housing, then the airbag resets, and the telescopic rod will retract into the sleeve, facilitating the next carton stacking operation.

[0016] Preferably, the clamping assembly includes a bidirectional screw rod rotatably connected to the inner side wall of the mounting hole. The end of the bidirectional screw rod is rotatably connected to the inner side wall of the rectangular chute. The outer side wall of the bidirectional screw rod is symmetrically threadedly connected with sliders, and the sliders are slidably connected inside the rectangular chute. The top of the slider is fixedly connected with a clamping plate. After the cartons are stacked, by rotating the bidirectional screw rod, the bidirectional screw rod rotates on the inner side wall of the mounting hole. During this process, the two sliders will approach or move away from each other on the inner side wall of the rectangular chute. During the process of the sliders approaching or moving away from each other, the cartons are moved to the center of the support plate through the clamping plates, thereby preventing the overall collapse of the device when the center of gravity of the stacked cartons is not at the center of gravity of the support plate.

[0017] Preferably, an arc-shaped groove is formed in the outer side wall of the housing at the position of the bidirectional screw rod. When the support plate moves on the inner side wall of the housing, the bidirectional screw rod moves inside the arc-shaped groove.

[0018] Preferably, a turntable is fixedly connected to the end of the bidirectional screw rod, and a rotating rod is fixedly connected to the eccentric position of the side wall of the turntable. When it is necessary to rotate the bidirectional screw rod, by rotating the rotating rod, the turntable drives the bidirectional screw rod to rotate, thereby achieving the purpose of convenience.

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] As Figures 1-5 shown, a finished product carton stacking rack includes a bottom plate 5 fixedly connected to the top of an outer shell 1. A plurality of rectangular blocks 3 are symmetrically and fixedly connected to the inner side wall of the outer shell 1. A support plate 2 is slidably connected to the inner side wall of the outer shell 1 above the rectangular blocks 3. A cavity 15 is formed inside the rectangular blocks 3. A pneumatic component is fixedly connected to the top of the rectangular blocks 3. The pneumatic component includes an airbag 16 fixedly connected to the top of the rectangular blocks 3. The top of the airbag 16 is fixedly connected to the bottom of the support plate 2. A round hole 17 is formed through the top of the rectangular blocks 3 at the position of the airbag 16, and the airbag 16 is communicated with the cavity 15. First, place the carton on the top of the support plate 2. Under the action of the gravity of the carton, the support plate 2 will slide downward along the inner side wall of the outer shell 1. During this process, the airbag 16 is compressed, and the gas inside the airbag 16 will enter the cavity 15 through the round hole 17. Then, as the airbag 16 is compressed, the air pressure inside the cavity 15 continuously increases. A sleeve 4 is fixedly connected to the inner side wall of the cavity 15. A telescopic component is slidably connected to the inner side wall of the sleeve 4. The telescopic component includes a piston 19 slidably connected to the inner side wall of the sleeve 4. A telescopic rod 20 is fixedly connected to the top of the piston 19. A through hole 14 is formed on the outer side wall of the lower end of the sleeve 4, and the sleeve 4 is communicated with the cavity 15. When the air pressure inside the cavity 15 continuously increases, the larger air pressure enters the sleeve 4 through the through hole 14. Then, under the action of the piston 19, the piston 19 drives the telescopic rod 20 to move upward along the inner side wall of the sleeve 4, thereby using the telescopic rod 20 to limit the stacked cartons and preventing the cartons from collapsing in the front of the device.

[0027] As Figure 2And 3 As shown in 3 , a rectangular chute 10 is formed at the top of the support plate 2, and a mounting hole 13 is formed in the side wall of the support plate 2. The mounting hole 13 communicates with the rectangular chute 10. A clamping assembly is rotatably connected to the inner side wall of the mounting hole 13. The clamping assembly includes a bidirectional lead screw 11 rotatably connected to the inner side wall of the mounting hole 13. The end of the bidirectional lead screw 11 is rotatably connected to the inner side wall of the rectangular chute 10. The outer side wall of the bidirectional lead screw 11 is symmetrically threadedly connected with sliders 12, and the sliders 12 are slidably connected inside the rectangular chute 10. The top of the slider 12 is fixedly connected with a clamping plate 9. After the cartons are stacked, by rotating the rotating rod 7, the bidirectional lead screw 11 is driven to rotate by the turntable 6, so that the bidirectional lead screw 11 rotates on the inner side wall of the mounting hole 13. During this process, the two sliders 12 will approach or move away from each other on the inner side wall of the rectangular chute 10. During the process of the sliders 12 approaching or moving away from each other, the carton is moved to the center of the support plate 2 through the clamping plate 9, thereby preventing the overall collapse of the device when the center of gravity of the stacked cartons is not at the center of gravity of the support plate 2.

[0028] As can be seen from the above, the specific implementation manner of the present utility model is as follows:

[0029] When the device is in use, first place the carton on the top of the support plate 2. Under the action of the gravity of the carton, the support plate 2 will slide downward along the inner side wall of the outer shell 1. During this process, the airbag 16 is compressed, and the gas inside the airbag 16 will enter the inside of the cavity 15 through the round hole 17. Then, as the airbag 16 is compressed, the air pressure inside the cavity 15 continuously increases. When the air pressure inside the cavity 15 continuously increases, the relatively high air pressure enters the inside of the sleeve 4 through the through hole 14. Then, under the action of the piston 19, the piston 19 drives the telescopic rod 20 to move upward along the inner side wall of the sleeve 4, thereby using the telescopic rod 20 to limit the stacked cartons, so as to prevent the cartons from collapsing in front of the device. After the cartons are stacked, by rotating the rotating rod 7, the bidirectional lead screw 11 is driven to rotate by the turntable 6, so that the bidirectional lead screw 11 rotates on the inner side wall of the mounting hole 13. During this process, the two sliders 12 will approach or move away from each other on the inner side wall of the rectangular chute 10. During the process of the sliders 12 approaching or moving away from each other, the carton is moved to the center of the support plate 2 through the clamping plate 9, thereby preventing the overall collapse of the device when the center of gravity of the stacked cartons is not at the center of gravity of the support plate 2.

[0030] The above are only the embodiments of the present utility model, and common general knowledge such as specific structures and characteristics known in the solutions is not described in detail herein. It should be noted that for those skilled in the art, without departing from the structure of the present utility model, several modifications and improvements can be made, and these should also be regarded as the protection scope of the present utility model, and these will not affect the implementation effect of the present utility model and the practicality of the patent. The protection scope required by this application shall be subject to the content of its claims, and the specific implementation manners and the like recorded in the specification can be used to interpret the content of the claims.
