[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0035] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0036] This application discloses a punching device for processing waterproof paper bags with a surface coating, which is applied to the punching process of waterproof paper bags with a surface coating.

[0037] It includes a support assembly 2, a moving assembly 3, a driving assembly 4, a connecting assembly 5, and a cutting assembly 6.

[0038] The cutting assembly 6 includes a connecting seat 601 and a punching tool 607. The connecting seat 601 has a through groove 602 on its upper surface and a stepped groove 603 on its top. Both sides of the connecting seat 601 have through openings 604. A fixing block 605 slides within the stepped groove 603. The guide design of the stepped groove 603 ensures precise sliding of the fixing block 605, guaranteeing vertical movement of the tool and preventing burrs or coating delamination caused by tilting. A threaded rod 606 is fixedly connected to the bottom surface of the fixing block 605. The top of the punching tool 607 has a threaded groove 608, and the threaded rod 606 is threaded into the threaded groove 608, enabling quick tool replacement to adapt to different hole diameter requirements. The fixing block 605 has an installation port 609, into which a bearing 6010 is embedded. The connecting seat 601 has a threaded opening 6011, and a long bolt 6012 is threaded into the threaded opening 6011. The fixing block 605 has a through hole 6013 running from left to right, and a hexagonal bolt 6014 is inserted into the through hole 6013. A nut 6015 is threaded into the hexagonal bolt 6014. There are two cutting components 6, which are symmetrically distributed about the connecting component 5. The end of the long bolt 6012 is connected to the bearing 6010 to reduce the frictional resistance during cutting and ensure the vertical movement accuracy of the tool. The end face of the nut 6015 overlaps the outer surface of the connecting seat 601. The hexagonal bolt 6014 passes through the through hole 6013 and two through holes 604 respectively. The hexagonal bolt 6014 is inserted into the through holes 604 and locked by the through bolt and nut 6015 to prevent radial displacement of the tool during operation.

[0039] The bracket assembly 2 includes a bracket 201. The top of the bracket 201 has a slot 202 and a threaded hole 203. The bottom of the bracket 201 is fixedly connected to a base 1. The base 1 and the bracket 201 provide overall rigid support, reducing the impact of processing vibration on accuracy.

[0040] The moving component 3 includes a mounting plate 301. A plug plate 302 is fixedly connected to the bottom surface of the mounting plate 301. The plug plate 302 is slidably fitted into the slot 202. A linear module 303 is mounted on the top surface of the mounting plate 301. The linear module 303 is selected according to the corresponding specifications and models of the equipment. The linear module 303 provides high-precision horizontal displacement to meet the requirements of complex hole layout. A screw 304 is threaded through the mounting plate 301. The end of the screw 304 is threaded into the threaded hole 203. A working groove is opened on the mounting plate 301. The sliding end of the linear module 303 passes through the working groove of the mounting plate 301.

[0041] The drive assembly 4 includes an electric push rod 401, the output end of which is fixedly connected to a connecting rod 402. The top of the electric push rod 401 is mounted on the sliding end of the linear module 303. The surface of the connecting rod 402 is threaded, and the connecting rod 402 is connected to the threaded cylinder 502 through the thread. The threaded design of the threaded cylinder 502 and the connecting rod 402 facilitates disassembly and maintenance, while transmitting driving force. The electric push rod 401 outputs stable vertical power with controllable stroke, avoiding tearing of the coating layer.

[0042] The connecting component 5 includes a connecting block 501, on the top of which a threaded cylinder 502 is embedded.

[0043] Working principle: The cutting component 6 is driven to move horizontally by the linear module 303 in the moving component 3. The insert plate 302 slides into the slot 202 of the bracket component 2, and the screw 304 is fixed to the threaded hole 203 to achieve precise horizontal positioning of the cutting component.

[0044] Vertical power is provided by the electric push rod 401 of the drive component 4. The electric push rod 401 selects the corresponding specification and model of the equipment according to the usage requirements, pushes the connecting rod 402 down, and drives the cutting component 6 to complete the punching action. When resetting, the electric push rod retracts and the punching cutter 607 disengages from the paper bag.

[0045] The cutting assembly 6 enables quick tool replacement through the threaded engagement of the threaded rod 606 and the punching tool 607. The insertion engagement of the hex bolt 6014 and the through-hole 604 ensures the stability of the fixing block 605. The design of the bearing 6010 and the long bolt 6012 reduces friction and makes the cutting process smooth.

[0046] Symmetrical processing: Two sets of symmetrically distributed cutting components 6 can work simultaneously or independently to adapt to the processing needs of multiple holes and improve efficiency.

[0047] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
