Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Specifically, the lifting device 4 includes a support box 41, a connecting plate 42, a motor 43, a screw rod 44 and a lifting plate 45. The support box 41 is arranged below the fixed column assembly 1 and the support rod 3, the connecting plate 42 is installed below the fixed column assembly 1 and the support rod 3 and at the top of the support box 41, the motor 43 is installed above the support box 41 and below the mounting frame 7, the screw rod 44 is installed on one side of the motor 43 close to the support box 41, and the lifting plate 45 is installed on the outside of the screw rod 44 and at the inner side of the support box 41 through threads.

[0024] By adopting the above technical solution, the staff can adjust the feeding height to a certain extent through the cooperation of the screw rod 44 and the lifting plate 45 and other structures when necessary, so as to better meet the working needs in different situations.

[0025] Specifically, the shape and size of the inner cross section of the support box 41 are the same as the shape and size of the outer cross section of the lifting plate 45 .

[0026] By adopting the above technical solution, it is ensured that the inner side of the support box 41 and the outer side of the lifting plate 45 can be closely attached to each other, thereby preventing the lifting plate 45 from rotating and deviating during movement, thereby ensuring normal operation.

[0027] Specifically, the buffer device 5 includes a damper 51 and an elastic rubber frame 52 . The elastic rubber frame 52 is installed between the connecting plate 42 and the lifting plate 45 . A plurality of dampers 51 are installed between the connecting plate 42 and the lifting plate 45 and inside the elastic rubber frame 52 .

[0028] By adopting the above technical solution, the mechanism can buffer the vibration occurring during the feeding process to a certain extent through the cooperation of the damper 51 and the elastic rubber frame 52, thereby reducing the possibility of adverse effects on the surrounding environment and personnel.

[0029] When the present embodiment is used, when it is necessary to use the mechanism to feed the punch press, the corresponding structure of the punch press is placed at the corresponding position of the support box 41 in the lifting device 4, and then the motor 43 is started.

The time required for the pushing assembly 6 to push the material each time is the feeding interval. The damper 51 and the elastic rubber frame 52 in the buffer device 5 can buffer the external vibration, and the support rod 3 plays a supporting and fixing role.

[0030] Example 2

[0031] The difference between this embodiment and embodiment 1 is that the cleaning and processing device 8 includes a fixed shell 81, a fan 82, a push plate 84, an electric telescopic rod 85 and a mesh frame 86. The fixed shell 81 is installed above the fixed column assembly 1, and the fan 82 is installed above the fixed shell 81. A mesh frame 86 is installed on one side of the top of the fixed column assembly 1. A push plate 84 is provided on the inner side of the mesh frame 86 and at a position on one side of the fixed shell 81. The mesh frame 86 and the push plate 84 are connected by an electric telescopic rod 85.

[0032] By adopting the above technical solution, the mechanism can clean the surface of the material to a certain extent through the cooperation of the fan 82 and the mesh frame 86 when necessary, so as to better meet the working needs in different situations.

[0033] Specifically, the cleaning device 8 further includes a filter 83 , and the filter 83 is installed on the inner side of the air inlet end of the fan 82 .

[0034] By adopting the above technical solution, the mechanism can prevent external impurities from entering the interior of the fan 82 through the filter 83, thereby reducing the possibility of accidental damage to the internal structure of the fan 82, thereby ensuring normal operation.

[0035] When this embodiment is used, when it is necessary to add materials to the fixed column assembly 1, the materials are placed in the mesh frame 86 in the cleaning and processing device 8, and the staff can start the fan 82 on the fixed shell 81. Under the action of the fan 82, the air filtered by the filter 83 is blown onto the materials, and the dust and other debris on the materials are separated by the airflow through the mesh frame 86, and then the electric telescopic rod 85 is started, and the electric telescopic rod 85 drives the push plate 84 to push the materials into the fixed column assembly 1, thereby adding materials to the fixed column assembly 1.

[0036] The structure and principle of the fixed column assembly 1 composed of a ball, a support block, a discharge port and a fixed column, the feed plate assembly 2 composed of a feed plate, a baffle, a roller, a rotating rod and a bearing, the support rod 3, the pushing assembly 6 composed of a fixed block and an electric telescopic rod, and the mounting frame 7 in the utility model have been disclosed in a high-speed precision punching machine automatic feeding device disclosed in Chinese patent application No. 201920197917.3. Its working principle is that when in use, the material is in the feed trough, and the material is pushed by the electric telescopic rod to push the material out of the discharge port and enter the upper end of the lower mold through the feed plate for stamping. The setting of the roller can reduce the material and the feed. The friction between the plates can reduce the resistance when the material moves, and the baffle can prevent the material from falling from the feeding plate; through the setting of multiple linkage mechanisms, the high-speed precision punching machine can automatically feed the material, so that the high efficiency of the punching machine can be effectively exerted, thereby improving production efficiency; at the same time, the support rod can play a certain supporting role on the feeding plate and enhance stability. The ball can reduce the friction between the material and the support block and reduce the movement resistance. The fixed block can enhance the stability of the position of the electric telescopic rod and improve the stability during work. The axonometric diagram can reduce the friction between the rotating rod and the feeding plate and reduce the rotation resistance. The height of the discharge port is higher than the lower mold, so that the material can slide from the feeding plate to the lower mold.

[0037] The structure and principle of the damper 51 in the utility model have been disclosed in a smart home washing machine shock absorbing device disclosed in Chinese patent application No. 201721446985.6. Its working principle consists of a piston and an oil tank, which is filled with oil. When the object moves, the piston moves in the oil, thereby consuming energy and slowing down the movement of the object.

[0038] The working principle and use process of the utility model are as follows: when it is necessary to use a mechanism to feed the punch press, the corresponding structure of the punch press is placed at the corresponding position of the support box 41 in the lifting device 4, and then the motor 43 is started. The motor 43 drives the screw rod 44 to rotate, and the screw rod 44 is threadedly connected to the lifting plate 45. The outer side of the lifting plate 45 and the inner side of the support box 41 are tightly attached to each other, so the screw rod 44 drives the lifting plate 45 and other structures to move, and then drives the connecting plate 42, the feeding plate assembly 2 and the fixed column assembly 1 and other structures to move, so as to adjust the feeding height, and then start the pushing assembly 6 in the mounting frame 7 to push the material onto the feeding plate assembly 2, and then the material slides along the feeding plate assembly 2 to the punch press, so as to carry out Feeding, the time required for the pushing component 6 to push the material each time is the feeding interval, the damper 51 and the elastic rubber frame 52 in the buffer device 5 can buffer the external vibration, and the support rod 3 plays a supporting and fixing role; when it is necessary to add material to the fixed column component 1, the material is placed in the mesh frame 86 in the cleaning and processing device 8, and the staff can start the fan 82 on the fixed shell 81. Under the action of the fan 82, the air filtered by the filter screen 83 is blown onto the material, and the dust and other debris on the material leave with the air flow through the mesh frame 86, and then the electric telescopic rod 85 is started, and the electric telescopic rod 85 drives the push plate 84 to push the material into the fixed column component 1, thereby adding material to the fixed column component 1.
