Technical Field

[0001] The utility model belongs to the technical field of middle-sealed bag processing equipment, and particularly relates to a punching device for middle-sealed bags. Background Art

[0002] A packaging bag refers to a bag used for packaging various articles, which facilitates storage and transportation of goods during the production and circulation process. Packaging bags are divided into various types according to the packaging form, and middle-sealed bags are one of them. When producing middle-sealed bags, punching is required on their surfaces, and a punching device is used.

[0003] In the prior art, a punch is generally used for punching. The middle of the punch is in a hollow state. When punching a middle-sealed bag, middle-sealed bag debris generated by punching is likely to remain inside the punch. If not cleaned in time, when the inside of the punch is filled with debris, it will affect the normal operation of the punch, thereby affecting the punching efficiency of the middle-sealed bag. Summary of the Invention

[0025] Reference Figures 1-5 , a punching device for a middle-sealed bag provided by an embodiment of the present utility model will now be described. A punching device for a middle-sealed bag includes a workbench 1. A clamping assembly 3 and a moving frame 6 are arranged at the upper end of the workbench 1. There are two groups of clamping assemblies 3. An adjusting mechanism 2 is arranged inside the workbench 1. The adjusting mechanism 2 is used to adjust the distance between the two clamping assemblies 3. A moving mechanism 4 is arranged at the rear end of the workbench 1. The moving mechanism 4 is used to drive the moving frame 6 to move. A cylinder 7 is fixedly connected to the upper end of the moving frame 6. The extending end of the cylinder 7 penetrates through the lower end of the moving frame 6 and is slidably connected to the moving frame 6. The extending end of the cylinder 7 is fixedly connected to a moving plate 10. A punching tool 9 is fixedly connected to the lower end of the moving plate 10. A pushing rod 13 is slidably arranged inside the punching tool 9. The upper end of the pushing rod 13 is fixedly connected to the moving frame 6.

[0026] Specifically, first, the distance between the two clamping assemblies 3 is adjusted by the adjusting mechanism 2 so that the clamping assembly 3 can clamp the middle-sealed bag. When the distance between the two clamping assemblies 3 is adjusted, the middle-sealed bag is fixed by the clamping assembly 3. Then, the moving mechanism 4 works to drive the moving frame 6 to move, so that the position of the punching tool 9 can be changed, so that the punching tool 9 can punch different positions of the middle-sealed bag. When the position of the punching tool 9 is determined, the cylinder 7 extends, and drives the punching tool 9 to move downward with the cooperation of the moving plate 10. Under the action of the punching tool 9, the middle-sealed bag is punched. After a punching operation is completed, the cylinder 7 contracts, and drives the punching tool 9 to move upward with the cooperation of the moving plate 10, so that the pushing rod 13 is inserted into the punching tool 9. Under the action of the pushing rod 13, the debris inside the punching tool 9 can be pushed out, thus realizing the cleaning of the punching tool 9 and being beneficial to the stable operation of the punching tool 9.

[0027] The adjusting mechanism 2 includes a first motor 201, a bidirectional threaded rod 202 and a threaded block 203. The bidirectional threaded rod 202 is rotatably connected inside the workbench 1. The threaded block 203 is threadedly connected to the circumferential surface of the bidirectional threaded rod 202. There are two threaded blocks 203, which are symmetrically distributed on the bidirectional threaded rod 202, and the internal thread directions of the two threaded blocks 203 are opposite. A square hole 12 is formed in the upper end surface of the workbench 1. The threaded block 203 is located inside the square hole 12 and is slidably connected to the square hole 12. A first motor 201 is fixedly connected to the side end of the workbench 1. The output end of the first motor 201 is fixedly connected to the bidirectional threaded rod 202. When the first motor 201 works, the output end of the first motor 201 drives the threaded block 203 to slide inside the square hole 12 under the cooperation of the bidirectional threaded rod 202, so as to change the distance between the two clamping components 3.

[0028] The clamping component 3 includes a U-shaped frame 301, a clamping plate 302, a connecting rod 303, a lifting rod 304 and a spring 305. The U-shaped frame 301 is fixedly connected to the upper end of the threaded block 203. The connecting rod 303 is slidably connected inside the U-shaped frame 301. The lifting rod 304 is fixedly connected to the upper end of the connecting rod 303. The clamping plate 302 is fixedly connected to the lower end of the connecting rod 303. A spring 305 is arranged on the circumferential surface of the connecting rod 303. One end of the spring 305 is fixedly connected to the U-shaped frame 301, and the other end of the spring 305 is fixedly connected to the clamping plate 302. When working, when clamping the middle-sealed bag, by pulling up the lifting rod 304, the clamping plate 302 is driven to move upward under the cooperation of the connecting rod 303, so as to facilitate placing one end of the middle-sealed bag between the clamping plate 302 and the U-shaped frame 301. When the clamping plate 302 moves upward, the spring 305 is compressed. The compressed spring 305 is beneficial to the reset of the clamping plate 302. After the middle-sealed bag is placed, release the lifting rod 304. Under the action of the compressed spring 305, the clamping plate 302 can be driven to move downward, and the middle-sealed bag is clamped and fixed under the cooperation of the clamping plate 302 and the U-shaped frame 301, effectively preventing the middle-sealed bag from shifting during punching.

[0029] The moving mechanism 4 includes a support plate 401, a lead screw 402, a second motor 403 and a slider 404. Support plates 401 are fixedly connected to both sides of the rear end of the workbench 1. The lead screw 402 is rotatably connected inside the support plate 401. The slider 404 is threadedly connected to the circumferential surface of the lead screw 402. The front end of the slider 404 is fixedly connected to the moving frame 6. A second motor 403 is fixedly connected to the left side of the support plate 401 located on the left side. The output end of the second motor 403 is fixedly connected to the lead screw 402. When the second motor 403 works, the output end of the second motor 403 drives the slider 404 to slide under the action of the lead screw 402, so as to drive the moving frame 6 to move, thus facilitating changing the position of the punching device 9.

[0030] A slide rail 5 is fixedly connected to the upper end of the workbench 1. The slide rail 5 is slidably connected to the moving frame 6. By providing the slide rail 5, during operation, the movement of the moving frame 6 can be limited under the action of the slide rail 5, so that the moving frame 6 can move smoothly.

[0031] A guide rod 8 is slidably connected inside the moving frame 6. The guide rod 8 is fixedly connected to the moving plate 10. By providing the guide rod 8, during operation, the movement of the moving plate 10 can be limited under the action of the guide rod 8, so that the moving plate 10 can move smoothly.

[0032] A backing plate 11 is fixedly connected to the front end of the moving frame 6. A circular hole 1101 is provided on the upper end surface of the backing plate 11. The diameter of the circular hole 1101 is larger than the diameter of the punching tool 9. By providing the backing plate 11, during operation, the lower end of the middle-sealed bag can be supported under the action of the backing plate 11 to prevent the middle-sealed bag from deforming during punching.

[0033] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
