Description

Technical Field

[0001] This utility model belongs to the field of paper packaging production technology, and in particular relates to a feeding and unloading device for paper packaging materials. Background Technology

[0002] In the production and processing of paper packaging materials, the loading and unloading of roll-shaped raw materials directly affects production efficiency and product quality. With the increasing demand for automation and intelligence in the packaging industry, traditional manual handling or simple mechanical assistance loading and unloading methods can no longer meet the requirements of large-scale, high-precision production. At the same time, packaging materials have stringent requirements for the clamping stability and rotation accuracy of rolls. Therefore, it is urgent to develop automated loading and unloading devices that integrate lifting, clamping, and rotation functions to improve production efficiency and reduce labor costs.

[0003] (1) Traditional loading and unloading equipment mostly uses independent mechanisms to complete lifting, clamping and rotating operations separately. For example, lifting relies on hydraulic jacks, clamping relies on mechanical grippers, and rotation requires an additional motor drive. The lack of linkage control between the components leads to time-consuming process connections and a high equipment failure rate.

[0004] (2) Although some automated equipment has integrated functions, it relies on multiple power sources and consumes more energy than a single power system. At the same time, traditional clamping structures (such as parallel grippers) are difficult to adapt to rolls of different diameters and require frequent manual adjustments, which cannot meet the diverse production needs of packaging materials. Utility Model Content

[0005] In response to the above situation and to overcome the shortcomings of the existing technology, this utility model provides a feeding and unloading device for paper packaging materials. It uses an air pump to drive gas into cylinder one and cylinder two, and triggers the conical clamping block to close through the threshold of the pressure relief valve, so that the lifting and clamping switching can be completed with a single air source. At the same time, the airflow of the flow-limiting hole drives the airflow fan to rotate, which drives the roller to rotate. The flow-limiting hole and the conical surface structure realize progressive adaptive clamping, shorten the cycle time, reduce energy consumption, and solve the problems of traditional equipment such as scattered functions, high energy consumption and poor clamping adaptability.

[0006] The technical solution adopted by this utility model is as follows: a feeding and unloading device for paper packaging materials, including a mounting platform, and also including a lifting component symmetrically arranged on the bottom wall of the mounting platform and a rotating clamping component symmetrically arranged on the side wall of the mounting platform, wherein the lifting component and the rotating clamping component are connected by pipes.

[0007] The rotary clamping assembly includes a second cylinder symmetrically fixed to the inner wall of the mounting platform, a push-pull cylinder horizontally sliding on one side wall of the second cylinder, a sliding connecting plate fixed to the end of the push-pull cylinder away from the second cylinder, a connecting shaft rotatably disposed through the sliding connecting plate, an airflow fan fixed to one end of the connecting shaft, and a conical clamping block rotatably disposed on one side wall of the sliding connecting plate. The conical clamping block is coaxially fixedly connected to the other end of the connecting shaft. The airflow fan is located inside the push-pull cylinder, and the airflow drives the airflow fan to rotate, converting the kinetic energy of the gas into mechanical energy. This mechanical energy, through the connecting shaft, drives the conical clamping block and the roll to rotate, thereby realizing the winding or unloading of paper packaging materials. A second piston is fixedly disposed at the end of the push-pull cylinder away from the sliding connecting plate. The piston two is movably and tightly fitted to the inner wall of the cylinder two. A flow-limiting hole is formed through the piston two, which restricts the flow rate and speed of gas entering the push-pull cylinder, causing the gas pressure inside the cylinder two to rise slowly and ensuring the smooth movement of the piston two. This enables the conical clamping block to progressively and stably clamp the drum, avoiding damage to the drum due to excessively rapid movement during clamping. The cylinder two and the push-pull cylinder are connected through the flow-limiting hole. An air outlet is formed through the circumferential side wall of the end of the push-pull cylinder near the sliding connecting plate. The cylinder two receives gas from the cylinder one through the connecting pipe. Under the action of the flow-limiting hole, the internal gas pressure gradually increases, pushing the piston two to move, which in turn drives the push-pull cylinder, the sliding connecting plate, and the conical clamping block to complete the clamping action of the drum.

[0008] As a preferred technical solution of this invention, the lifting assembly includes a cylinder 1 symmetrically and vertically fixedly mounted on the bottom wall of the mounting platform, a piston 1 movably and closely fitted inside the cylinder 1, and a connecting column vertically and slidably mounted on the upper wall of the cylinder 1. The upper wall of the piston 1 is fixedly connected to the lower end of the connecting column, and a lifting support is fixedly mounted on the upper end of the connecting column. After the air pump inputs gas, the gas pressure inside the cylinder 1 increases, pushing the piston 1 upward, thereby driving the connecting column and the lifting support to rise, completing the lifting action of the drum. At the same time, when the piston 1 reaches its limit position, it provides a pressure source for the gas to flow to the cylinder 2.

[0009] As a preferred technical solution of this invention, a connecting pipe is fixedly installed through the side wall of the mounting platform. The two ends of the connecting pipe are respectively connected to cylinder one and cylinder two. The sliding connecting plate is horizontally slidably installed on the outer wall of the connecting pipe. One end of the connecting pipe is fixed and connected to a pressure relief valve, which is located inside cylinder one.

[0010] As a preferred technical solution of this invention, a flow divider box is fixedly provided on the bottom wall of the mounting platform, and the flow divider box is internally connected to the cylinder.

[0011] As a preferred technical solution of this invention, an air pump is fixedly installed on the top wall of the distribution box, and the air outlet of the air pump is connected to the interior of the distribution box.

[0012] As a preferred technical solution of this invention, the upper wall of the lifting support is arc-shaped, and ball bearings are embedded and movable within the arc-shaped upper wall of the lifting support.

[0013] The beneficial effects of this utility model after adopting the above structure are as follows:

[0014] (1) Gas is driven by an air pump to fill cylinder one and cylinder two in sequence. The air pressure threshold is set by the pressure relief valve. When cylinder one is lifted to the position, the high pressure gas automatically triggers cylinder two to drive the conical clamping block to close. The lifting and clamping action is switched with a single air source. The time for loading and unloading is shortened and the efficiency is improved. This solves the problems of dispersed functions and poor coordination of traditional equipment and simplifies the operation process.

[0015] (2) The kinetic energy generated by the flow of gas through the flow-limiting hole is used to drive the airflow fan to rotate. The connecting shaft drives the conical clamping block and the roller to rotate synchronously, converting the gas pressure energy into rotational mechanical energy. Compared with the traditional motor-driven rotation, the energy consumption is reduced and the rotation speed is stable, overcoming the defects of high energy consumption of multiple power sources in existing equipment.

[0016] (3) By controlling the intake speed of cylinder 2 through the flow limiting hole, piston 2 can be smoothly pushed to gradually clamp the conical clamping block; the conical structure can be used to automatically adjust the clamping force according to the change of the drum diameter, which can stably clamp drums of different diameters, and there is no impact during the clamping process, avoiding damage to the drum surface; it is suitable for materials of different hardness, solving the problem of poor adaptability and easy material damage of traditional clamping structures.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1-4 As shown, a feeding and unloading device for paper packaging materials includes a mounting platform 1, a lifting assembly 3 symmetrically arranged on the inner bottom wall of the mounting platform 1, and a rotating clamping assembly 4 symmetrically arranged on the inner side wall of the mounting platform 1. The lifting assembly 3 and the rotating clamping assembly 4 are connected by pipes. The rotating clamping assembly 4 includes a second cylinder 7 symmetrically fixedly arranged on the inner side wall of the mounting platform 1, a push-pull cylinder 20 horizontally slidably arranged on one side wall of the second cylinder 7, a sliding connecting plate 11 fixedly arranged at the end of the push-pull cylinder 20 away from the second cylinder 7, a connecting shaft 15 rotatably arranged through the sliding connecting plate 11, and a connecting shaft 15 fixedly arranged on the connecting shaft 15. An airflow fan 14 is located at one end of a sliding connecting plate 11, and a conical clamping block 17 is rotatably mounted on one side wall of the sliding connecting plate 11. The conical clamping block 17 is coaxially fixedly connected to the other end of the connecting shaft 15. The airflow fan 14 is located inside the push-pull cylinder 20. A piston 22 is fixedly mounted at the end of the push-pull cylinder 20 away from the sliding connecting plate 11. The piston 22 is movably and tightly mounted on the inner wall of the cylinder 27. A flow-limiting hole 13 is opened through the piston 22. The cylinder 27 and the push-pull cylinder 20 are connected through the flow-limiting hole 13. An air outlet 16 is opened through the circumferential side wall of the end of the push-pull cylinder 20 near the sliding connecting plate 11.

[0025] The lifting assembly 3 includes a cylinder 6 symmetrically and vertically fixed to the bottom wall of the mounting platform 1, a piston 8 movably and closely fitted inside the cylinder 6, and a connecting column 9 vertically and slidably mounted on the upper wall of the cylinder 6. The upper wall of the piston 8 is fixedly connected to the lower end of the connecting column 9. A lifting support 10 is fixedly mounted on the upper end of the connecting column 9. The upper wall of the lifting support 10 is arc-shaped, and ball bearings are embedded and movable within the arc-shaped upper wall of the lifting support 10. A distribution box 19 is fixedly mounted on the bottom wall of the mounting platform 1. The flow divider box 19 is internally connected to cylinder 6. An air pump 2 is fixedly installed on the top outer wall of the flow divider box 19, and the outlet end of the air pump 2 is internally connected to the flow divider box 19. A connecting pipe 5 is fixedly installed through the side wall of the mounting platform 1. The two ends of the connecting pipe 5 are internally connected to cylinder 6 and cylinder 7, respectively. The sliding connecting plate 11 is horizontally slidably installed on the outer wall of the connecting pipe 5. One end of the connecting pipe 5 is fixed and internally connected to a pressure relief valve 18, which is located inside cylinder 6.

[0026] In practical use, the drum is first placed on the lifting support 10, and then the air pump 2 is started. The outside air is pumped into the distribution box 19 through the air pump 2, and then into the cylinder 6. As the air in the cylinder 6 is continuously filled with gas, it pushes the piston 8, the connecting column 9 and the lifting support 10 to move upward synchronously. When the piston 8 moves to the limit position, the gas in the cylinder 6 continues to be input, causing the internal air pressure of the cylinder 6 to rise. When the air pressure reaches the preset threshold, the gas in the cylinder 6 flows into the cylinder 7 through the pressure relief valve 18 and the connecting pipe 5. At this time, due to the flow restriction effect of the flow restriction hole 13, the air pressure in the cylinder 7 slowly rises, pushing the piston 12 to move, which in turn drives the push-pull cylinder 20 and the sliding connecting plate 11 to move horizontally, so that the conical clamping block 17 converges towards the center synchronously. By abutting the outer periphery of the drum with its conical surface, the drum is clamped and fixed.

[0027] Airflow enters the push-pull cylinder 20 through the flow-limiting hole 13 and is then discharged to the outside through the air outlet 16. During this process, the airflow drives the airflow fan 14 to rotate, which in turn drives the conical clamping block 17 to rotate through the connecting shaft 15, thereby causing the roll to rotate and realizing the winding and feeding or unfolding and unloading of paper packaging materials.

[0028] If any person skilled in the art, inspired by this invention, designs a similar structure or embodiment without departing from the spirit of this invention, such design should fall within the protection scope of this invention.
