Description

Technical Field

[0001] This application relates to the technical field of material processing and treatment, and in particular to a die-cutting machine that facilitates waste removal. Background Technology

[0002] Die-cutting machines, as key equipment in industries such as packaging and printing, play a vital role in modern industrial production. With the rapid development of the packaging industry and the increasing demand for product personalization and diversification, the application range of die-cutting machines is becoming increasingly widespread, greatly improving production efficiency and product quality, and driving the modernization of the packaging and printing industry. They can precisely cut various paper, plastic, and other materials into the required shapes and sizes to meet the packaging requirements of different products, holding an indispensable position in many fields such as food, pharmaceuticals, and cosmetics.

[0003] In traditional die-cutting machines, waste removal is usually done manually. No treatment is done during processing; after die-cutting, personnel manually remove the waste paper from the processing area and dispose of it centrally. Alternatively, some machines use simple blowers to try and blow the waste paper away from the work area, but this is ineffective and can even cause paper scraps to fall into the die-cutting machine, damaging the mechanical structure. Summary of the Invention

[0004] To overcome the above-mentioned technical problems, this application provides a die-cutting machine that facilitates waste removal.

[0005] The die-cutting machine for easy waste removal provided in this application adopts the following technical solution: A convenient waste-removing die-cutting machine includes a frame, an unwinding mechanism and a rewinding mechanism located at both ends of the frame, and a feeding mechanism, a die-cutting mechanism, and a pulling mechanism for pulling the paper tape arranged sequentially along a first direction on the frame. The die-cutting mechanism includes a die-cutting chamber, an upper die base for mounting the upper die, a lower die base for mounting the lower die, and a first driving mechanism. The first driving mechanism is drivenly connected to the upper die base via a fixed connecting seat to drive the upper die base to move closer to or away from the lower die base in a vertical direction. The die-cutting chamber has a paper inlet and a paper outlet on both sides for paper tape to enter and exit. The top of the die-cutting chamber has an opening for the fixed connecting seat to pass through, and the outline of the opening matches the outline of the fixed connecting seat. The lower die base is located in the die-cutting chamber and has a waste paper trough inside. The waste paper trough is connected to a collection box, and the collection box is connected to a negative pressure pump.

[0006] By adopting the above technical solution, the unwinding mechanism and the rewinding mechanism, together with the feeding mechanism and the pulling mechanism, can realize the conveying of the paper tape. The first driving mechanism drives the upper die base to approach or move away from the lower die base to complete the die-cutting operation. The opening contour and the fixed connecting seat contour can prevent debris from entering the die-cutting chamber or waste paper from leaving the die-cutting chamber. The waste paper trough in the lower die base can collect the waste paper generated by die-cutting. The waste paper is sucked into the collection box by the negative pressure pump to achieve the purpose of convenient waste removal.

[0007] Optionally, the first driving mechanism includes a hydraulic rod, which is arranged vertically downwards. The main body of the hydraulic rod is fixedly connected to the frame, and the output rod of the hydraulic rod is fixedly connected to the fixed connecting seat.

[0008] By adopting the above technical solution, a hydraulic rod is used as the first driving mechanism. Its main body is fixed on the frame, and the output rod is fixedly connected to the fixed connecting seat. It can stably drive the upper die seat to move closer to or away from the lower die seat in the vertical direction, so as to realize the die-cutting operation of the paper tape.

[0009] Optionally, the die-cutting mechanism further includes a pressure plate. The die-cutting chamber has pressure grooves on both side walls of the paper inlet and paper outlet. The bottom of one of the two pressure grooves is connected to the paper inlet, and the other is connected to the paper outlet. The top openings of both pressure grooves are located at the top of the die-cutting chamber. The length of the pressure groove along the second direction perpendicular to the first direction, the length of the paper inlet along the second direction, and the length of the paper outlet along the second direction are all equal. The pressure plate is disposed in the pressure groove. The first driving mechanism is connected to the pressure plate to drive the pressure plate to reciprocate in the vertical direction.

[0010] By adopting the above technical solution, pressure grooves are set on both sides of the die-cutting chamber and the pressure plate is driven by the first driving mechanism to move back and forth in the vertical direction within the pressure grooves. This can position and press the paper strip during the die-cutting process, prevent the paper strip from shifting, and improve the die-cutting accuracy.

[0011] Optionally, the first driving mechanism further includes a movable connecting seat, which is slidably connected to the output rod of the hydraulic rod. The output rod of the hydraulic rod is provided with an upper limit retaining ring and a lower limit retaining ring. The lower limit retaining ring is located between the upper limit retaining ring and the fixed connecting seat. The movable connecting seat is located between the upper limit retaining ring and the lower limit retaining ring. The pressure plate is fixedly connected to the bottom of the movable connecting seat.

[0012] By adopting the above technical solution, the output rod of the hydraulic rod is slidably connected through a moving connecting seat. This design allows the output rod to maintain a certain degree of flexibility during the driving process. An upper limit retaining ring and a lower limit retaining ring are set on the output rod. These two retaining rings together limit the movement range of the moving connecting seat, ensuring the stability and controllability of the transmission process. The bottom of the moving connecting seat is fixedly connected to the pressure plate. Therefore, when the output rod of the hydraulic rod moves, this movement is transmitted to the pressure plate through the moving connecting seat. The pressure plate then reciprocates vertically, achieving the positioning and clamping effect on the paper tape.

[0013] Optionally, the first drive mechanism further includes a spring, which is sleeved on the output rod of the hydraulic rod. One end of the spring is connected to the upper limit stop ring, and the other end is connected to the top of the moving connection seat.

[0014] By adopting the above technical solution, during the die-cutting process, when the pressure plate moves downward, it can use its own weight to press the paper tape, preventing the paper tape from shifting during the die-cutting process. Furthermore, the spring design absorbs impacts and vibrations during transmission, ensuring smooth movement of the pressure plate. Additionally, after the pressure plate contacts the paper tape, the hydraulic rod's output rod continues to move downward, driving the upper die to continue moving downward. At this time, the spring is compressed, allowing the pressure plate to fit more tightly against the paper tape surface, further enhancing the pressing effect.

[0015] Optionally, a sponge pad is provided at the bottom of the pressure plate.

[0016] By adopting the above technical solution, a sponge pad is installed at the bottom of the pressure plate. On the one hand, this can avoid direct hard contact between the pressure plate and the paper tape, reduce damage to the paper tape, protect the surface of the paper tape, and enhance the cushioning effect on the paper tape. On the other hand, the sponge can be used to seal the gap between the pressure plate and the paper inlet or paper outlet, preventing waste paper scraps from leaving the die-cutting chamber and ensuring a clean working environment.

[0017] Optionally, a straightening mechanism is provided between the feeding mechanism and the unwinding mechanism, and between the pulling mechanism and the winding mechanism. The straightening mechanism is connected to the frame and includes two straightening components spaced apart along a second direction perpendicular to the first direction, and a second driving component drivenly connected to the straightening components to drive the straightening components to move closer or further apart from each other.

[0018] By adopting the above technical solution, a correction mechanism is set between the feeding mechanism and the unwinding mechanism, and between the pulling mechanism and the winding mechanism. The two correction components and the second drive component of the correction mechanism can be used to make the two correction components move closer or further away from each other to correct the position of the paper tape, ensuring the straightness and stability of the paper tape during the conveying process, and avoiding the paper tape deviation from affecting the subsequent die-cutting or winding operations.

[0019] Optionally, the correction component includes a correction frame, on which a plurality of rollers are arranged vertically and at equal intervals in the first direction.

[0020] By adopting the above technical solution, the straightening frame can effectively support the rollers, and the arrangement of the rollers ensures that the paper tape remains flat during the conveying process, reducing friction.

[0021] Optionally, the second drive assembly includes a motor and a bidirectional lead screw. The bottom of the correction assembly is provided with a slider, and the frame is provided with a sliding groove that cooperates with the slider. The slider is threadedly connected to two threaded sections of the bidirectional lead screw. The main body of the motor is connected to the frame, and the drive end of the motor is drivenly connected to the bidirectional lead screw to drive the bidirectional lead screw to rotate around its own axis.

[0022] By adopting the above technical solution, when the motor is working, the bidirectional lead screw drives the slider to move in the slide groove, thereby causing the straightening components to move closer or further apart, realizing the adjustment of the paper tape position and ensuring the smooth progress of the die-cutting and winding process.

[0023] Optionally, both the feeding mechanism and the pulling mechanism include a conveying assembly. The conveying assembly includes a conveying frame, an electric push rod, a driving roller, and a driven roller. The conveying frame is fixedly connected to the machine frame, and the driving roller is fixedly connected to the conveying frame. A slide rail is provided on the conveying frame in the vertical direction. The roller shaft of the driven roller is located in the slide rail. The main body of the electric push rod is fixedly connected to the conveying frame, and the output end of the electric push rod is connected to the roller shaft of the driven roller to drive the roller shaft of the driven roller to reciprocate along the slide rail, thereby causing the driven roller to move closer to or away from the driving roller.

[0024] By adopting the above technical solution, the electric push rod drives the driven roller to approach or move away from the active roller, which can adjust the distance between the two to adapt to the feeding of paper tapes of different thicknesses. On the other hand, when the paper tape is corrected by the correction mechanism, the electric push rod pushes the driven roller away from the active roller to ensure that the paper tape does not wrinkle or break during the correction process.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting a waste paper trough connected to the collection box in the lower die base and connecting the collection box to a negative pressure pump, waste paper can be actively and efficiently collected, solving the problems of low efficiency and incomplete cleaning of traditional waste removal methods, avoiding the accumulation of waste paper at the die-cutting station, and ensuring the quality of subsequent die-cutting; 2. A correction mechanism is set between the feeding mechanism and the unwinding mechanism, and between the pulling mechanism and the winding mechanism. This mechanism can drive the correction components to move closer or further apart to correct the conveyed paper tape and ensure the accuracy of the paper tape delivery. 3. The electric push rod of the conveying component can drive the driven roller to move closer to or further away from the driving roller, which can adapt to the conveying of paper tapes of different thicknesses and enhance the applicability of the die-cutting machine.

Detailed Implementation

[0029] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0030] This application discloses a die-cutting machine that facilitates waste removal.

[0031] like Figure 1 and Figure 2 As shown, the die-cutting machine for easy waste removal includes a frame 6, an unwinding mechanism 1, a rewinding mechanism 5, a feeding mechanism, a die-cutting mechanism 4, and a pulling mechanism. The unwinding mechanism 1 and the rewinding mechanism 5 are located at both ends of the frame 6. The feeding mechanism, the die-cutting mechanism 4, and the pulling mechanism are arranged sequentially on the frame 6 along the first direction. The feeding mechanism is used to convey the paper tape 7, and the pulling mechanism is used to pull the paper tape 7. This combination enables the paper tape 7 to smoothly complete the conveying and die-cutting process in the die-cutting machine, improving the overall operating efficiency of the die-cutting machine.

[0032] Specifically, the unwinding mechanism 1 is the component that releases the paper tape 7 to be processed, while the rewinding mechanism 5 is the component that collects the paper tape 7 after die-cutting. Both the unwinding mechanism 1 and the rewinding mechanism 5 are common technical means in this field, so their structures will not be described in detail here.

[0033] like Figure 1 and Figure 2As shown, the die-cutting mechanism 4 includes a die-cutting chamber 401, an upper die holder 402, a lower die holder 403, and a first driving mechanism. The upper die holder 402 is used to mount the upper die, and the lower die holder 403 is used to mount the lower die. In this embodiment, the upper die is constructed as a combination of a die-cutting blade and a creasing blade, and the lower die is constructed as a slotted plate that cooperates with the upper die. The die-cutting chamber 401 is the space for performing die-cutting operations. The lower die holder 403 is located inside the die-cutting chamber 401. The first driving mechanism is driven to the upper die holder 402 through a fixed connecting seat 404, so as to drive the upper die holder 402 to move closer to or away from the lower die holder 403 in the vertical direction, thereby realizing the die-cutting action on the paper tape 7. The die-cutting chamber 401 has a paper inlet 4012 and a paper outlet 4013 on both sides for the paper feeding belt 7 to enter and exit. The top has an opening for the fixed connecting seat 404 to pass through. The outline of the opening matches the outline of the fixed connecting seat 404, which ensures the sealing of the die-cutting chamber 401 and prevents external debris from entering or paper scraps from leaving the die-cutting chamber 401.

[0034] Specifically, the die-cutting chamber 401 can be a square box structure, welded from steel plates. The internal space size can be determined based on the dimensions of the upper die holder 402 and the lower die holder 403. The paper inlet 4012 and the paper outlet 4013 are located on opposite side walls of the die-cutting chamber 401, and their height and length along the second direction ensure smooth passage of the paper tape 7. The top opening profile is designed according to the shape of the fixed connecting seat 404; the profiles of both cooperate to prevent dust and debris from entering the die-cutting chamber 401 from the opening, while also preventing paper scraps from leaving the die-cutting chamber 401 from the opening. The upper die holder 402 and the lower die holder 403 are typically block structures made of high-strength alloy steel, possessing good wear resistance and rigidity, and capable of withstanding the pressure during the die-cutting process. The upper mold can be fixedly connected to the upper mold base 402 via a pull-out structure and bolts. Similarly, the lower mold can be fixedly connected to the lower mold base 403 via a pull-out structure and bolts. In some other embodiments, the upper and lower molds can be fixed to the upper mold base 402 or lower mold base 403 via other connection methods; this application does not impose any limitations on this. The fixed connecting seat 404 is a connecting component; it can be a square plate that is fixed to the upper mold base 402 by welding and then connected to the output end of the first drive mechanism to transmit driving force to the upper mold base 402.

[0035] like Figure 1 and Figure 2As shown, the first driving mechanism includes a hydraulic rod 408, which is vertically downward. The main body of the hydraulic rod 408 is fixedly connected to the frame 6, and the output rod of the hydraulic rod 408 is fixedly connected to the fixed connecting seat 404. The hydraulic rod 408 is a commonly used linear drive device, characterized by large driving force and smooth movement. The main body of the hydraulic rod 408 is a cylinder containing a piston and a piston rod. The piston rod, also known as the output rod, moves linearly under the pressure of hydraulic oil. When hydraulic oil enters the rodless chamber of the cylinder, the piston rod extends, causing the upper die holder 402 to move downwards towards the lower die holder 403 for die cutting. When hydraulic oil enters the rod chamber of the cylinder, the piston rod retracts, and the upper die holder 402 moves upwards away from the lower die holder 403. The hydraulic rod 408 can also be replaced by a pneumatic cylinder. The working principle of a pneumatic cylinder is similar to that of the hydraulic rod 408, except that the driving medium is compressed air. It has the advantage of fast response speed, but the driving force is relatively small, making it suitable for applications where the driving force requirement is not particularly high.

[0036] like Figure 1 and Figure 2 As shown, a waste paper trough 405 is provided inside the lower die base 403, which is connected to a collection box 406. The collection box 406 is connected to a negative pressure pump 407. Waste paper generated during the die-cutting process falls into the waste paper trough 405, and then, under the action of the negative pressure pump 407, is sucked into the collection box 406 for centralized processing. The waste paper trough 405 can be a groove formed inside the lower die base 403, and its shape can be designed according to actual needs. The collection box 406 is generally a sealed box made of plastic or metal, with a certain volume to hold a large amount of waste paper. The negative pressure pump 407 is the component that provides suction; it can be a vacuum pump that continuously extracts air from the collection box 406, creating a negative pressure inside, thereby sucking the waste paper from the waste paper trough 405. A multi-layer filter screen for blocking waste paper flakes can be installed at the connection point between the collection box 406 and the vacuum pump.

[0037] like Figure 1 and Figure 2As shown, the die-cutting mechanism 4 also includes a pressure plate 409. The die-cutting chamber 401 has a paper inlet 4012 and a paper outlet 4013. Pressure grooves 4011 are provided on both side walls. The bottom of one of the pressure grooves 4011 is connected to the paper inlet 4012, and the other is connected to the paper outlet 4013. The top openings of both pressure grooves 4011 are located at the top of the die-cutting chamber 401. The lengths of the pressure grooves 4011 in the second direction, the lengths of the paper inlet 4012 in the second direction, and the lengths of the paper outlet 4013 in the second direction are all equal. The pressure plate 409 is disposed within the pressure grooves 4011. A first driving mechanism is connected to the pressure plate 409 to drive the pressure plate 409 to reciprocate vertically. The function of the pressure plate 409 is to press the paper strip 7 tightly during the die-cutting process, ensuring the accuracy and quality of the die-cutting. The pressure plate 409 can be a flat plate made of plastic or metal, with a smooth and flat surface. The pressure groove 4011 is a groove formed on the side wall of the die-cutting chamber 401. Its size and shape match the pressure plate 409, allowing the pressure plate 409 to move freely up and down within the pressure groove 4011.

[0038] The first drive mechanism also includes a moving connecting seat 410, an upper limit retaining ring 4081, a lower limit retaining ring 4082, and a spring 411. The moving connecting seat 410 is slidably connected to the output rod of the hydraulic rod 408. The upper limit retaining ring 4081 and the lower limit retaining ring 4082 are disposed on the output rod of the hydraulic rod 408. The lower limit retaining ring 4082 is located between the upper limit retaining ring 4081 and the fixed connecting seat 404. The moving connecting seat 410 is located between the upper limit retaining ring 4081 and the lower limit retaining ring 4082. The pressure plate 409 is fixedly connected to the bottom of the moving connecting seat 410. The spring 411 is sleeved on the output rod of the hydraulic rod 408. One end of the spring 411 is connected to the upper limit retaining ring 4081, and the other end is connected to the top of the moving connecting seat 410. When the upper mold base 402 is located at the position furthest from the lower mold base 403, the horizontal height of the bottom surface of the pressure plate 409 is lower than the horizontal height of the upper mold base 402. When the output rod of the hydraulic rod 408 moves downward, the moving connecting seat 410 also moves downward. After the pressure plate 409 comes into contact with the paper tape 7, the output rod of the hydraulic rod 408 continues to move downward, and the spring 411 is compressed, so that the pressure plate 409 can fit more tightly against the surface of the paper tape 7, further enhancing the pressing effect. When the output rod moves upward, the spring 411 relaxes, and the lower limit retaining ring 4082 drives the moving connecting seat 410 to return to its original position.

[0039] A sponge pad can also be provided at the bottom of the pressure plate 409. The sponge pad can increase the friction between the pressure plate 409 and the paper tape 7, while preventing the pressure plate 409 from damaging the paper tape 7. On the other hand, the sponge can be used to seal the gap between the pressure plate 409 and the paper inlet 4012 or the paper outlet 4013, preventing waste paper scraps from leaving the die-cutting chamber 401 and ensuring a clean working environment.

[0040] like Figure 1 and Figure 2 As shown, a straightening mechanism 3 is provided between the feeding mechanism and the unwinding mechanism 1, and between the pulling mechanism and the winding mechanism 5. The straightening mechanism 3 is connected to the frame 6 and includes two straightening components and a second drive component. The function of the straightening mechanism 3 is to straighten the position of the paper tape 7, ensuring the accuracy of the paper tape 7 during the conveying and die-cutting process. The two straightening components are spaced apart along a second direction perpendicular to the first direction. The second drive component is driven by the straightening components to drive the straightening components to move closer or further apart from each other.

[0041] Specifically, the straightening assembly includes a straightening frame 301 and multiple rollers 302. The straightening frame 301 supports the rollers 302. The rollers 302 are arranged vertically and at equal intervals in a first direction. The arrangement of multiple rollers 302 allows the paper tape 7 to be better guided and straightened when passing through the straightening assembly. The second drive assembly includes a motor 303, a bidirectional lead screw 304, a slider 3011, and a groove 601. The main body of the motor 303 is connected to the frame 6, and the drive end of the motor 303 is driven by the bidirectional lead screw 304 to drive the bidirectional lead screw 304 to rotate around its own axis. The slider 3011 is threadedly connected to two threaded sections of the bidirectional lead screw 304, and the frame 6 is provided with a groove 601 that mates with the slider 3011. When the motor 303 drives the bidirectional lead screw 304 to rotate, since the two threaded sections of the bidirectional lead screw 304 rotate in opposite directions, the slider 3011 will move towards or away from each other in the slide groove 601, thereby driving the correction components to move closer or further away from each other, so as to realize the correction function of paper tapes 7 of different widths.

[0042] like Figure 1 and Figure 2 As shown, both the feeding mechanism and the pulling mechanism include a conveying assembly 2. The conveying assembly 2 includes a conveying frame 201, an electric push rod 202, a driving roller 203, and a driven roller 204. The conveying frame 201 is fixedly connected to the frame 6, and the driving roller 203 is fixedly connected to the conveying frame 201. A slide rail is provided on the conveying frame 201 along the vertical direction. The roller shaft of the driven roller 204 is located in the slide rail. The main body of the electric push rod 202 is fixedly connected to the conveying frame 201, and the output end of the electric push rod 202 is connected to the roller shaft of the driven roller 204 to drive the roller shaft of the driven roller 204 to reciprocate along the slide rail, thereby causing the driven roller 204 to move closer to or away from the driving roller 203. The driving roller 203 is the driving component of the conveying assembly 2. The driving roller 203 can be an electric roller. The driving roller 203, in conjunction with the driven roller 204, drives the paper belt 7 to move. The driven roller 204 can adjust the distance between itself and the driving roller 203 as needed to accommodate paper tapes 7 of different thicknesses, or to ensure that the paper tape 7 does not wrinkle or break during the straightening process.

[0043] The implementation principle of this die-cutting machine with convenient waste removal is as follows: This die-cutting machine with convenient waste removal achieves efficient die-cutting and convenient waste removal functions through the coordinated work of various mechanisms. The cooperation of the unwinding mechanism 1 and the rewinding mechanism 5 ensures the supply and collection of the paper tape 7, and the feeding mechanism and the pulling mechanism enable the paper tape 7 to be smoothly transported in the die-cutting machine. The hydraulic rod 408 of the die-cutting mechanism 4 drives the upper die base 402 to perform the die-cutting action, while the pressure plate 409, with the cooperation of the moving connecting seat 410 and the spring 411, presses the paper tape 7, improving the die-cutting accuracy. The waste paper trough 405 and the collection box 406 in the lower die base 403 can collect the waste paper generated by die-cutting in a timely manner under the action of the negative pressure pump 407, avoiding the accumulation of waste paper from affecting the die-cutting quality. The straightening mechanism 3 can straighten the position of the paper tape 7, ensuring the accuracy of die-cutting. The entire die-cutting machine overcomes the problems of low efficiency and incomplete cleaning of existing waste removal methods, and improves the working efficiency and die-cutting quality of the die-cutting machine. It has made significant improvements and enhancements compared with existing technologies.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
