Description

Technical Field

[0001] The invention belongs to the technical field of woven bag processing equipment, and in particular relates to a woven bag continuous punching machine. Background Art

[0002] Woven bags, also known as snakeskin bags, are a type of plastic bag used for packaging. They are typically made from various chemical plastics such as polyethylene and polypropylene. Existing woven bags are made from polypropylene (PP) as the primary raw material, which is extruded and stretched into flat yarns that are then woven, braided, and made into bags.

[0003] Woven bags initially come in rolls, requiring punching and sewing to form the finished product. However, feedback from frontline workers indicates that any problems with the punching mechanism on existing woven bag production lines require the entire line to be shut down until the punching mechanism is repaired, replaced, and debugged. This time-consuming and labor-intensive repair, replacement, and debugging of the punching mechanism significantly impacts regular woven bag production schedules. Therefore, designing a continuous punching machine for woven bags that avoids downtime and allows for continuous production has become a pressing technical challenge. Summary of the Invention

[0004] The present invention provides a cutting module adopted by a continuous cutting machine for woven bags, in which the punching mechanisms on multiple main mounting frames on a fixed plate are all in a standby state after installation and debugging. When a punching mechanism on a main mounting frame fails, the failed main mounting frame is disconnected, and another main mounting frame is quickly replaced and fixed to the second support frame by moving on the slide rail through a slide groove. The woven bag processing production line can be restored in a very short time, which greatly reduces the time for repairing, replacing and debugging the punching mechanism and does not affect the normal production scheduling of the woven bags.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] A continuous punching machine for woven bags comprises a cutting table, a continuous punching device and a collection box. A cutting groove is provided in the middle of the cutting table, and the continuous punching device is arranged in the middle of the cutting groove; the continuous punching device comprises a first support frame, a second support frame and a main mounting frame, the top of the first support frame is provided with a slide rail, the slide rail is provided with a slide groove, the top of the slide groove is provided with a fixed plate, one end of the main mounting frame is hinged on the fixed plate, and one end of the main mounting frame is detachably connected to the second support frame, a telescopic rod is provided in the middle position of the main mounting frame, the telescopic section of the telescopic rod passes downward through the main mounting frame, and an auxiliary mounting frame is provided at the end of the telescopic section of the telescopic rod, the auxiliary mounting frame is arranged parallel to the main mounting frame, and a punching mechanism is installed at the bottom of the auxiliary mounting frame; the collection box is arranged below the cutting groove.

[0007] The main mounting frame is provided with a handle on one side of the first support frame, and the other end of the main mounting frame can be lifted upward by operating the handle.

[0008] The second support frame is provided with an L-shaped fixing block, which is fixed to the main mounting frame via a latch.

[0009] The slide groove on the slide rail is an electric slide groove, and a position switch is provided on the electric slide groove.

[0010] The L-shaped fixing block on the second support frame is an electromagnet.

[0011] At least three main mounting frames are provided on the fixing plate, and a support plate corresponding to the main mounting frames is also provided on the fixing plate, and the support plate is a magnet support plate.

[0012] The punching mechanism on the auxiliary mounting frame is a resistance wire cutting mechanism, a laser cutting mechanism, an ultrasonic cutting mechanism or a punching blade.

[0013] The collection box is a rectangular structure with an open top; the side of the collection box is provided with a first plug interface, an exhaust port and a second plug interface from top to bottom; a plug block is provided on the first plug interface, and the plug block is provided with an electrostatic generator with a grid structure; an axial flow fan is provided in the exhaust port; and a material receiving drawer is provided in the second plug interface.

[0014] The cutting table is provided with several mounting grooves, and a correction mechanism is provided on the mounting grooves; the correction mechanism includes a fixed screw, a positioning block and a nut, the positioning block is passed through the fixed screw, and a flange is provided at the bottom of the fixed screw; a sliding rod is passed through the positioning block, and the sliding rod is arranged perpendicular to the fixed screw, and a correction block is provided at the end of the sliding rod, and the sliding rod is fixed by a tightening bolt.

[0015] The telescopic rod on the main mounting frame is a hydraulic telescopic rod, a pneumatic telescopic rod or an electric push rod. Beneficial effects

[0016] By adopting the above technical solution, the beneficial effects of the present invention are:

[0017] Compared with the punching and cutting devices on the existing woven bag processing production line, the punching and cutting module adopted by the woven bag continuous cutting machine provided by the present invention is that the punching and cutting mechanisms on the multiple main mounting frames on the fixed plate are all in a standby state after installation and debugging. When the punching and cutting mechanism on a main mounting frame fails, the failed main mounting frame is disconnected, and another main mounting frame is quickly replaced and fixed to the second support frame by moving the slide groove on the slide rail.

[0018] The main mounting frame and the fixed plate are riveted in a detachable manner. When the punching mechanism of a main mounting frame fails, the failed main mounting frame can be easily removed from the fixed plate and moved to a dedicated maintenance site for maintenance without affecting the woven bag processing production line.

[0019] The top of the collection box is open. When the axial flow fan of the exhaust port is running, the opening of the collection box will generate negative pressure. The debris falling from the cut position of the woven bag is absorbed into the collection box by the negative pressure. When the debris moves downward, it contacts the electrostatic generator with a grid structure and generates static electricity. The debris is adsorbed to the electrostatic generator with a grid structure. When the electrostatic generator is fully adsorbed, the axial flow fan is turned off, the electrostatic generator is powered off, and the debris falls downward into the receiving drawer. The staff can clean the receiving drawer regularly.

[0020] Different resistance wire cutting mechanisms, laser cutting mechanisms, ultrasonic cutting mechanisms or punching blades can be installed on the main mounting frame according to operation requirements to meet different woven bag cutting requirements.

[0021] To sum up, the punching module adopted by the woven bag continuous cutting machine provided by the present invention, the punching mechanisms on multiple main mounting frames on the fixed plate are all in a standby state after installation and debugging. When the punching mechanism on a main mounting frame fails, the failed main mounting frame is disconnected, and another main mounting frame is quickly replaced and fixed to the second support frame through the slide groove on the slide rail. The woven bag processing production line can be restored in a very short time, which greatly reduces the time for repairing, replacing and debugging the punching mechanism and does not affect the normal production scheduling of the woven bags.

[0034] In the description of the present invention, it should also be noted that, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to mechanical connections or electrical connections; they may refer to direct connections or indirect connections through an intermediate medium; and they may refer to internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0036] like Figures 1-11As shown, a continuous punching machine for woven bags includes a cutting table 1, a continuous punching device and a collecting box 2. A cutting groove 3 is opened in the middle of the cutting table 1, and the continuous punching device is arranged in the middle of the cutting groove 3; the continuous punching device includes a first support frame 4, a second support frame 5 and a main mounting frame 6. The top of the first support frame 4 is provided with a slide rail 7, the slide rail 7 is provided with a slide groove 8, the top of the slide groove 8 is provided with a fixed plate 9, one end of the main mounting frame 6 is hinged to the fixed plate 9, and one end of the main mounting frame 6 is detachably connected to the second support frame 5. A telescopic rod 10 is provided in the middle position of the main mounting frame 6, and the telescopic section of the telescopic rod 10 passes downward through the main mounting frame 6. An auxiliary mounting frame 11 is provided at the end of the telescopic section of the telescopic rod 10. The auxiliary mounting frame 11 is arranged parallel to the main mounting frame 6, and a punching mechanism is installed at the bottom of the auxiliary mounting frame 11; the collecting box 2 is arranged below the cutting groove 3. A plurality of main mounting frames 6 are arranged on a fixed plate 9, and a punching mechanism is installed on an auxiliary mounting frame 11 of the main mounting frame 6. The auxiliary mounting frame 11 is pushed downward by the telescopic rod 10 to enable the punching mechanism to cut the woven bag. When the punching mechanism fails, the main mounting frame 6 can be quickly replaced and connected to the second support frame 5 by moving the fixed plate 9, thereby achieving the technical purpose of quickly replacing the punching mechanism, so that the cutting operation of the woven bag processing equipment is highly continuous.

[0037] The main mounting frame 6 is provided with a handle 12 on one side of the first support frame 4. The handle 12 can be operated to lift the other end of the main mounting frame 6 upward. The handle 12 makes it convenient for the staff to lift the other end of the main mounting frame 6 upward, making it convenient to replace another main mounting frame 6 and connect it to the second support frame 5.

[0038] An L-shaped fixing block 13 is provided on the second support frame 5, and the fixing block 13 is fixed to the main mounting frame 6 through a pin 14. The other end of the main mounting frame 6 is connected to the fixing block 13 and fixed through the pin 14, so that the main mounting frame 6 is in a fixed cutting position.

[0039] The slide 8 on the slide rail 7 is an electric slide 8, which is provided with a position switch. The electric slide 8 is controlled by a PLC controller to enable the fixed plate 9 on the top of the slide 8 to move automatically.

[0040] The L-shaped fixing block 13 on the second support frame 5 is an electromagnet. The fixing block 13 realizes automatic connection and disconnection between the main mounting frame 6 and the second support frame 5 under the control of the PLC controller.

[0041] At least three main mounting frames 6 are provided on the fixed plate 9. A specified number of main mounting frames 6 can be set on the fixed plate 9 according to the operation requirements to meet the operation requirements of rapid switching and continuous cutting of woven bags; the fixed plate 9 is also provided with a support plate 15 corresponding to the main mounting frame 6, and the support plate 15 is a magnetic support plate 15. After the main mounting frame 6 is erected, the support plate 15 can not only support the main mounting frame 6, but also adsorb and fix the main mounting frame 6 to prevent the main mounting frame 6 from flipping over and falling.

[0042] The punching mechanism on the auxiliary mounting frame 11 is a resistance wire cutting mechanism, a laser cutting mechanism, an ultrasonic cutting mechanism or a punching blade, and different punching mechanisms can be replaced according to different cutting requirements.

[0043] The collecting box 2 is a rectangular structure with an open top; the side of the collecting box 2 is provided with a first plug port 16, an exhaust port 17 and a second plug port 18 from top to bottom; a plug block is provided on the first plug port 16, and the plug block is provided with an electrostatic generator 19 with a grid structure; an axial flow fan is provided in the exhaust port 17; a material receiving drawer is provided in the second plug port 18. The collecting box 2 can effectively prevent the debris generated by the broken end of the woven bag from flying around when the woven bag is cut, thereby ensuring a clean and hygienic production environment.

[0044] like Figure 9 As shown, the cutting table 1 is provided with a plurality of mounting grooves 20, and the mounting grooves 20 are provided with a correction mechanism; the correction mechanism includes a fixed screw 21, a positioning block 22 and a nut 23, the positioning block 22 is passed through the fixed screw 21, and the bottom of the fixed screw 21 is provided with a flange; a sliding rod 24 is passed through the positioning block 22, and the sliding rod 24 is vertically arranged to the fixed screw 21, and a correction block 25 is provided at the end of the sliding rod 24, and the sliding rod 24 is fixed by a tightening bolt 26. The correction block 25 of the correction mechanism can be adjusted left and right and up and down on the cutting table 1 to clamp the woven bag in the specified position space to prevent the woven bag from deviating and warping during operation.

[0045] The telescopic rod 10 on the main mounting frame 6 is a hydraulic telescopic rod 10, a pneumatic telescopic rod 10 or an electric push rod. Example

[0046] At least three main mounting frames 6 are provided on the fixed plate 9, and each mounting frame is equipped with a punching mechanism. The punching mechanisms of the three main mounting frames 6 are all debugged and are in standby state. When the woven bag processing equipment produces a production line, one of the punching mechanisms is used for cutting operation. When the punching mechanism fails, the failed main mounting frame 6 is quickly brought over, and the mobile fixed plate 9 moves one of the spare main mounting frames 6 to the cutting position. The normal operation of the woven bag processing equipment can be restored in a very short time, and the continuous cutting operation of the woven bag can be realized; the collecting box 2 is located below the cutting groove 3, and the top of the collecting box 2 is open. After the axial flow fan of the exhaust port 17 is running, the opening of the collecting box 2 will generate negative pressure. The debris falling from the cutting position of the woven bag is absorbed into the collecting box 2 by the negative pressure. When the debris moves downward, it contacts the electrostatic generator 19 of the grid structure to generate static electricity and is adsorbed to the electrostatic generator 19 of the grid structure. After the electrostatic generator 19 is fully adsorbed, the axial flow fan is turned off, the electrostatic generator 19 is powered off, and the debris falls down into the receiving drawer. The staff can clean the receiving drawer regularly. Example

[0047] 2-10 main mounting frames 6 are provided on the fixed plate 9, and different punching mechanisms are installed on the main mounting frames 6. Different punching mechanisms can be quickly switched according to the operation requirements to meet the woven bag cutting operations with different cutting requirements. Example

[0048] The main mounting frame 6 is riveted to the fixed plate 9. When the punching mechanism of a main mounting frame 6 fails, the failed main mounting frame 6 can be easily removed from the fixed plate 9 and moved to a dedicated maintenance site for maintenance without affecting the woven bag processing production line. Example

[0049] The continuous punching device can be conveniently set up on the existing woven bag processing production line, and has a good connection and matching effect with the existing woven bag processing production line, thereby reducing the cost of modifying the existing equipment.

[0050] By adopting the above technical solution, the effects of the present invention are:

[0051] The punching module adopted by the woven bag continuous cutting machine provided by the present invention is that the punching mechanisms on the multiple main mounting frames 6 on the fixed plate 9 are all in a standby state after installation and debugging. When the punching mechanism on one main mounting frame 6 fails, the failed main mounting frame 6 is disconnected, and another main mounting frame 6 is quickly replaced and fixed to the second support frame 5 by moving on the slide rail 7 through the slide groove 8. The woven bag processing production line can be restored in a very short time, which greatly reduces the time for repairing, replacing and debugging the punching mechanism and does not affect the normal production schedule of the woven bags.

[0052] The main mounting frame 6 and the fixing plate 9 are detachably riveted. When the punching mechanism of a main mounting frame 6 fails, the failed main mounting frame 6 can be easily removed from the fixing plate 9 and moved to a dedicated maintenance site for maintenance without affecting the woven bag processing production line.

[0053] The top of the collection box 2 is open. When the axial flow fan of the exhaust port 17 is running, the opening of the collection box 2 will generate negative pressure. The debris falling from the cut position of the woven bag is absorbed into the collection box 2 by the negative pressure. When the debris moves downward, it contacts the electrostatic generator 19 with a grid structure to generate static electricity and is adsorbed onto the electrostatic generator 19 with a grid structure. After the electrostatic generator 19 is fully adsorbed, the axial flow fan is turned off, the electrostatic generator 19 is powered off, and the debris falls downward into the receiving drawer. The staff can clean the receiving drawer regularly.

[0054] Different resistance wire cutting mechanisms, laser cutting mechanisms, ultrasonic cutting mechanisms or punching blades can be installed on the main mounting frame 6 according to the operation requirements to meet different woven bag cutting requirements.

[0055] To sum up, the punching module adopted by the woven bag continuous cutting machine provided by the present invention, the punching mechanisms on the multiple main mounting frames 6 on the fixed plate 9 are all in a standby state after installation and debugging. When the punching mechanism on a main mounting frame 6 fails, the failed main mounting frame 6 is disconnected, and the other main mounting frame 6 is quickly replaced and fixed to the second support frame 5 by moving on the slide rail 7 through the slide groove 8. The woven bag processing production line can be restored in a very short time, which greatly reduces the time for repairing, replacing and debugging the punching mechanism and does not affect the normal production scheduling of the woven bags.

[0056] The electrostatic generator 19, resistance wire cutting mechanism, laser cutting mechanism, ultrasonic cutting mechanism or punching blade used in the present invention are all existing conventional technologies, and their specific structures will not be described in detail.

[0057] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
