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. Their raw materials are generally various chemical plastic materials such as polyethylene and polypropylene. Existing woven bags are made of polypropylene (English name pp) as the main raw material, which is extruded and stretched into flat yarns, and then woven, knitted, and made into bags.

[0003] The initial state of woven bags is in the form of rolls, which need to be punched and sewn by processing companies to form finished woven bags. However, according to feedback from front-line workers in the workshop, once a problem occurs with the punching device on the existing woven bag processing equipment production line, the entire processing equipment production line needs to be shut down, and production can only be resumed after the punching device is repaired, replaced and debugged. However, the maintenance, replacement and debugging of the punching device are time-consuming and labor-intensive, which seriously affects the normal woven bag production schedule. Therefore, designing a continuous punching machine for woven bags that can avoid shutdowns and can produce continuously has become a technical problem that needs to be solved at present. Summary of the invention

[0004] The present invention provides a cutting module adopted by a woven bag continuous cutting machine, 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: A continuous punching machine for woven bags comprises a cutting table, a continuous punching device and a collecting 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 supporting frame, a second supporting frame and a main mounting frame, a slide rail is provided on the top of the first supporting frame, a slide groove is provided on the slide rail, a fixed plate is provided on the top of the slide groove, 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 supporting 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, 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 collecting box is arranged below the cutting groove.

[0006] The main mounting frame is provided with a handle on one side of the first supporting frame, and the other end of the main mounting frame can be lifted upward by operating the handle.

[0007] The second support frame is provided with an L-shaped fixing block, which is fixed to the main mounting frame via a latch.

[0008] The slide slot on the slide rail is an electric slide slot, and a position switch is provided on the electric slide slot.

[0009] The L-shaped fixing block on the second support frame is an electromagnet.

[0010] At least three main mounting frames are arranged on the fixing plate, and a supporting plate corresponding to the main mounting frames is also arranged on the fixing plate, and the supporting plate is a magnet supporting plate.

[0011] 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.

[0012] The collecting box is a rectangular structure with an open top; a first plug interface, an exhaust port and a second plug interface are provided on the side of the collecting box from top to bottom in sequence; a plug block is provided on the first plug interface, and a grid-structured electrostatic generator is provided on the plug block; an axial flow fan is provided in the exhaust port; and a material receiving drawer is provided in the second plug interface.

[0013] The cutting table is provided with a plurality of mounting grooves, and a correction mechanism is provided on the mounting grooves; the correction mechanism comprises a fixing screw, a positioning block and a nut, the positioning block is passed through the fixing screw, and a flange is provided at the bottom of the fixing screw; a sliding rod is passed through the positioning block, the sliding rod is vertically arranged with the fixing screw, a correction block is provided at the end of the sliding rod, and the sliding rod is fixed by a tightening bolt.

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, so that 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 bag. 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. 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 to generate static electricity and 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. Different resistance wire cutting mechanisms, laser cutting mechanisms, ultrasonic cutting mechanisms or punching blades can be installed on the main mounting frame according to the operation requirements to meet different woven bag cutting requirements.

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 without affecting the normal production scheduling of the woven bags.

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

[0021] like Figure 1-Figure 11As shown, a continuous punching machine for woven bags comprises 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 comprises a first support frame 4, a second support frame 5 and a main mounting frame 6. A slide rail 7 is provided on the top of the first support frame 4, a slide groove 8 is provided on the slide rail 7, a fixed plate 9 is provided on the top of the slide groove 8, one end of the main mounting frame 6 is hinged on the fixed plate 9, and one end of the main mounting frame 6 is detachably connected to the second supporting 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, and 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 a telescopic rod 10 so that the punching mechanism cuts 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 and making the cutting operation of the woven bag processing equipment produce a strong continuity.

[0022] 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, so as to facilitate the replacement of another main mounting frame 6 and the connection with the second support frame 5.

[0023] The second support frame 5 is provided with an L-shaped fixing block 13, which is fixed to the main mounting frame 6 via a latch 14. The other end of the main mounting frame 6 is connected to the fixing block 13 and fixed via the latch 14, so that the main mounting frame 6 is in a fixed cutting position.

[0024] The slide 8 on the slide rail 7 is an electric slide 8, and a position switch is provided on the electric slide 8. The fixed plate 9 on the top of the slide 8 is automatically moved by the control of the PLC controller.

[0025] The L-shaped fixing block 13 on the second supporting frame 5 is an electromagnet. The fixing block 13 realizes automatic connection and disconnection between the main mounting frame 6 and the second supporting frame 5 through the control of the PLC controller.

[0026] 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 fast switching and continuous cutting of woven bag cutting; 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 magnet 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 absorb and fix the main mounting frame 6 to prevent the main mounting frame 6 from flipping over and falling.

[0027] 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.

[0028] The collecting box 2 is a rectangular structure, and the top of the collecting box 2 is open; 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; and 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.

[0029] like Fig. 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 a flange is provided at the bottom of the fixed screw 21; a sliding rod 24 is passed through the positioning block 22, and the sliding rod 24 is vertically arranged with 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 tilting during operation.

[0030] 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

[0031] At least three main mounting frames 6 are arranged on the fixed plate 9, and a set of punching mechanisms are installed on each mounting frame. 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, and the fixed plate 9 is moved to move 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 downward into the receiving drawer. The staff can clean the receiving drawer regularly. Example

[0032] 2-10 main mounting frames 6 are arranged on the fixed plate 9, and different punching and cutting mechanisms are installed on the main mounting frames 6. Different punching and cutting mechanisms can be quickly switched according to the operation requirements to meet the woven bag cutting operations with different cutting requirements. Example

[0033] 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

[0034] The continuous punching device can be conveniently arranged on the existing woven bag processing production line, has a good connection and matching effect with the existing woven bag processing production line, and reduces the cost of transformation of the existing equipment.

[0035] By adopting the above technical solution, the effects of the present invention are: The punching module used in the continuous cutting machine for woven bags provided by the present invention has punching mechanisms on multiple main mounting frames 6 on the fixed plate 9 that are all in a standby state after installation and debugging. When a punching mechanism on a 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. 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. The top of the collection box 2 is open, and the axial flow fan of the exhaust port 17 will generate negative pressure when it is running. 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. When 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. 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.

[0036] 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 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 without affecting the normal production scheduling of the woven bags.

[0037] The electrostatic generator 19, the resistance wire cutting mechanism, the laser cutting mechanism, the ultrasonic cutting mechanism or the punching blade used in the present invention are all existing conventional technologies, and their specific structures will not be described in detail.

[0038] 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. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
