Technical Field

[0001] The invention relates to the technical field of packaging devices, in particular to a planetary roller screw packaging device with an automatic cutting function. Background Art

[0002] In recent years, with the continuous progress of automation technology and mechanical engineering, the packaging industry has gradually moved towards intelligence and automation. Traditional packaging methods mainly rely on manual operation or semi-automatic equipment, but these methods have disadvantages such as low efficiency, poor precision, and cumbersome operation.

[0003] There are many types of packaging equipment and solutions on the market, including pneumatic and hydraulic driven packaging systems. Most of these devices focus on improving packaging speed and packaging accuracy. For example, pneumatically driven balers can complete the work during the tightening and winding of packaging materials.

[0004] With regard to the above-mentioned prior art, firstly, the lack of tension change causes the packaging material to become loose or uneven, thus affecting the packaging quality; secondly, the lack of protection for individual parts causes wear and tear when parts collide; finally, although many existing packaging equipment have achieved partial automation, manual intervention is still required to adjust packaging parameters or handle abnormal situations, thus affecting the overall automation level and efficiency. Therefore, those skilled in the art provide a planetary roller screw packaging device with automatic cutting function to solve the problems raised in the above background. Summary of the invention

The cutting mechanism and the clamping mechanism are tightly connected, the winding mechanism and the clamping mechanism are tightly connected, and the tensioning mechanism and the winding mechanism are tightly connected. The tensioning mechanism is used to maintain the tension of the material. The cutting mechanism is used to cut the positioned packaging material to a fixed length or at a fixed point. The clamping mechanism is used to stably clamp and guide the planetary roller screw. The winding mechanism is used to surround and wrap the planetary roller screw.

The tensioning mechanism is used to maintain the tension of the packaging material, ensure the stability of the packaging material, and avoid loosening or unevenness during the packaging process. The cutting mechanism is used to cut the positioned packaging material to a fixed length or a fixed point to ensure the accurate packaging length. The clamping mechanism is used to stably clamp and guide the planetary roller screw to prevent the screw from deviating or running unsteadily during operation, ensuring high precision during the packaging process. The winding mechanism is used to surround and cover the planetary roller screw to fix and protect the screw. By adopting the above technical solution, the packaging device is automated, precise and efficient, effectively improving the packaging quality and production efficiency.

[0009] Furthermore, the clamping mechanism includes a feeding assembly, a clamping assembly and an electric slide rail. The feeding assembly and the winding mechanism are fastened together, the electric slide rail and the feeding assembly are fastened together, and the electric slide rail and the clamping assembly are transmission-connected.

[0010] By adopting the above technical solution, the clamping mechanism is designed as a multifunctional structure, and the precise feeding and stable clamping of the packaging material are achieved through the close connection of the feeding component, the clamping component and the electric slide rail. The feeding component is tightly connected to the winding mechanism to ensure the stability during the feeding process; the electric slide rail is tightly connected to the feeding component, and the feeding component can move smoothly through the drive of the electric slide rail to ensure the smooth transmission of the material; the transmission connection between the electric slide rail and the clamping component realizes the precise displacement of the clamping component, so that the clamping mechanism can be adjusted at any time during the material transmission process, thereby improving the clamping accuracy. By adopting the above technical solution, the clamping mechanism can accurately clamp and position the planetary roller screw to ensure the efficiency and accuracy of the material packaging process.

[0011] Furthermore, the loading assembly includes a lifting hydraulic cylinder, a lifting block, an airbag, a loading box and a limiting transmission belt. The lifting hydraulic cylinder and the loading box are fastened together, the lifting hydraulic cylinder and the lifting block are transmission-connected, the airbag and the lifting block are fastened together, the lifting blocks are arranged in a stepped manner, and the limiting transmission belt is used to control the loading rate of the planetary roller screw.

[0012] By adopting the above technical solution, the feeding assembly is a key component of the clamping mechanism, and its function is to provide stable material transportation. The lifting hydraulic cylinder is tightly connected to the feeding box, and the working drive of the hydraulic cylinder enables the feeding box to move up and down, which is convenient for the supply of materials. The lifting hydraulic cylinder is connected to the lifting block by transmission, and the lifting block is driven by hydraulic pressure to ensure that the packaging material enters the system smoothly. The airbag and the lifting block are tightly connected, and the airbag can adjust the air pressure as needed to control the lifting speed of the lifting block, thereby further improving the stability of feeding. The stepped arrangement design of the lifting block helps to improve the stability and uniformity of material transmission. The limiting transmission belt accurately controls the feeding rate to avoid excessively fast or slow material transportation, ensuring that the feeding process of the planetary roller screw is smooth and orderly. By adopting the above technical solution, the feeding assembly can accurately control the feeding process, ensure the stable transmission of materials, and avoid packaging failures caused by unstable material supply. Furthermore, the clamping mechanism includes a clamping block, a sliding block, a clamping claw, a clamping electromagnetic block, a clamping elastic part, a clamping magnetic block, a rotating motor, a sliding screw, a sliding motor, a clamping frame and a movable wire rail.

The fastening connection between the sliding motor and the clamping block enables the clamping block to move accurately in different directions under electric drive. The transmission connection between the sliding motor and the sliding screw further improves the moving accuracy of the clamping block. The connection between the rotating motor and the clamping frame enables the entire clamping frame to rotate according to demand, which is convenient for adjusting the clamping position. The clamping electromagnetic block and the clamping block achieve stable control of the clamping force through magnetic attraction or repulsion, preventing the clamping from being too loose or too tight. The combination of the clamping elastic member with the clamping electromagnetic block and the clamping magnetic block makes the force in the clamping process more uniform and reduces the error during clamping. The moving wire rail ensures that the clamping frame can move smoothly and accurately during the entire clamping process. By adopting the above technical solution, the clamping mechanism realizes efficient and accurate clamping operation, and improves the overall accuracy and stability of the packaging system.

The outer winding block is designed as a circular ring to meet the winding requirements of different diameters. The winding motor drives the rotation of the outer winding block by connecting with the winding frame, thereby realizing the winding operation of the screw. The connection between the tape motor and the tape column is responsible for the traction and tensioning of the tape to ensure the tension and stability of the tape during the winding process. By adopting the above technical solution, the winding mechanism can efficiently and stably wrap the planetary roller screw around, thereby protecting the screw and improving the tightness and integrity of the packaging.

[0016] Furthermore, the inner winding component includes a moving block, a reset column, a reset motor, an inner winding frame, a vertical electromagnetic block, a vertical magnetic block and a vertical elastic member.

The cutting block is connected to the outer winding block so that after the winding is completed, the cutting process can be completed automatically to achieve precise cutting of the packaging material. The automation of the cutting process can effectively improve the packaging efficiency and ensure that the length of each cutting is consistent, avoiding waste caused by human operation errors.

The pressure sensor monitors the pressure changes of the tension rod in real time to ensure the stability of the tension during the winding process. The opposite motor adjusts the tension rod through the adjustment of the direction block to control the tension of the packaging material. Through the precise control of the opposite motor, it can be ensured that the tension of the material during the winding process is always maintained in an ideal state.
