Description

Technical Field

[0001] The invention relates to the technical field of steel strip processing, and in particular to a precision steel strip winding and cutting integrated machine. Background Art

[0002] Steel belt refers to a conveyor belt made of carbon steel that is used as the traction and carrying component of a belt conveyor. It can also be used to bundle goods. It is a narrow and long steel plate produced by various steel rolling companies to meet the needs of industrial production of various metal or mechanical products in different industrial sectors.

[0003] In the field of steel strip production technology, the production of steel strip is a thin steel strip obtained by rolling, physical and chemical surface treatment of thicker raw steel strip. The raw steel strip passes continuously on the pre-arranged processing equipment to finally obtain a thin steel strip that meets the requirements. Stainless steel strip is an extension of ultra-thin stainless steel plate, which is mainly used to meet the industrial production of various metal or mechanical products in different industrial sectors.

[0004] Whether it is collecting materials after production in the factory or transporting materials outside the factory, in order to save volume and avoid bending of the steel strip, it is usually necessary to roll the steel strip. During the process of rolling the steel strip, a winding mechanism will be used for the winding operation.

[0005] After the steel strip is coiled, cutting equipment is usually used to cut the steel strip to facilitate the storage and transportation of the coiled steel strip.

[0006] The steel strip winding equipment in the prior art, such as the Chinese patent with application number 202221238752.8, authorization announcement number CN217577575U, and titled "A steel strip winding machine", discloses a steel strip winding machine, which includes two mounting plates, a flattening roller and a winding roller rotatably arranged between the two mounting plates, and also includes a distance adjustment mechanism arranged at the ends of the flattening roller to adjust the distance between the two flattening rollers and a positioning mechanism to position the ends of the two flattening rollers. The winding machine in the above patent can flatten and wind steel strips of different thicknesses.

[0007] Another example is the Chinese patent with application number 202221039016.X, authorization announcement number CN217253741U, and name of a cold-rolled steel strip cutting device. In the above patent, a cold-rolled steel strip cutting device includes a frame, an adsorption device and a cutting device; the adsorption device includes a chassis and an air duct assembly arranged at the bottom of the chassis, the upper surface of the chassis is provided with a plurality of through holes, a cavity is provided in the chassis, and the plurality of through holes are connected to the cavity; the input end of the air duct assembly is connected to the chassis and connected to the cavity, and the air duct assembly is used to generate an air duct that passes through the through holes, the cavity and the air duct assembly in sequence; the cutting device is arranged on the frame, and the cutting device cooperates with the adsorption device to cut the cold-rolled steel strip. The above patent solves the problem of slow cutting efficiency of the traditional manual cutting method, and has the advantages of simple structure and low manufacturing cost.

[0008] In the production and processing methods of steel strips in the prior art, such as the above-mentioned patents, the steel strip is generally wound up with a winding roller, and then the wound steel strip is cut with a cutting device, so that the wound steel strip is separated from the steel strip production line. It is well known that the thickness of the steel strip will gradually increase with the number of turns of the steel strip during the winding process, until it reaches a predetermined thickness, and then the cutting device is used for cutting. However, the winding roller and the cutting device in the prior art are separately arranged, and the cutting device can only be turned on for cutting after the staff observes that the predetermined winding requirements are met and closes the winding roller, which affects the work efficiency to a certain extent. It can be seen from this that how to drive the winding roller that has been wound up to stop rotating on one device, while passively realizing the cutting operation of the wound steel strip by the cutting device, is a problem that needs to be solved urgently. Summary of the invention

[0009] The object of the present invention is to provide a precision steel strip winding and cutting integrated machine to solve the problems raised in the above-mentioned background technology.

[0012] Furthermore, the trigger mechanism includes a first rack installed on the protective plate, a transmission gear is rotatably connected to the frame, and a second rack is also slidably connected to the frame, the first rack and the second rack are respectively meshed on the upper and lower sides of the transmission gear; a driving block is fixedly connected to the second rack, and a force-bearing block is installed on the trigger rod through a mounting plate, and the driving block intermittently abuts against the force-bearing block.

[0013] Furthermore, an elastic cylinder is installed on the frame, and a synchronization member is arranged between the elastic cylinder and the driving rod; the power unit includes a driving rack fixedly connected to the cutting knife, and also includes a driving gear, the driving gear is meshed with the driving rack, and the series member is arranged between the elastic cylinder and the driving gear.

[0014] Furthermore, the series component includes a series block, which is fixedly connected to the linkage rod. The linkage rod is slidably connected in the elastic tube, and an adaptation groove that matches the series block is opened on the side wall of the driving gear. The series block abuts against the adaptation groove; and the linkage rod and the force block are fixedly connected by a fixing rod.

[0015] Furthermore, a positioning frame is provided on the frame, a positioning plate is installed inside the positioning frame, and multiple groups of strong springs are provided between the positioning plate and the positioning frame. The elastic force of the strong springs drives the positioning plate to abut against the steel strip body; when the power unit drives the cutting knife to slide downward to cut the steel strip body, the positioning plate positions the steel strip body.

[0016] Furthermore, a locking piece is arranged between the positioning plate and the positioning frame, and the locking piece fixes the positioning plate inside the positioning frame; the locking piece includes a locking rod slidably connected to the inside of the positioning frame, a locking groove matched with the locking rod is opened on the positioning plate, and a locking spring is arranged between the locking rod and the positioning frame, and the elastic force of the locking spring drives the locking rod to be clamped in the locking groove to fix the positioning plate.

Since the protective plate fits the steel strip body, when the thickness of the steel strip body gradually increases, the protective plate will be passively driven to slide. When the protective plate slides a certain stroke (that is, when it is about to reach the predetermined thickness of the steel strip body), it will begin to contact the trigger mechanism. As the protective plate slides, the intermittent connection mechanism will be driven to move through the trigger mechanism, so that the power of the servo motor is separated from the winding roller. At this moment, the winding roller will stop rotating, so as to facilitate the later cutting of the steel strip body on the winding roller. At the same time, when the winding roller stops rotating, it is also convenient to disassemble the winding roller from the frame, and the use effect is better.

[0021] Furthermore, during the process in which the trigger mechanism drives the intermittent connection mechanism to disengage from the winding roller, the trigger mechanism also drives the series connection member to be connected to the power unit, so that the servo motor drives the cutting knife to move downward through the power unit to cut the steel strip body, without the need to separately set up a cutting mechanism to cut the steel strip body.

[0022] Furthermore, the device can passively stop the winding roller from rotating and stop the winding operation according to the requirements of the steel strip body of a predetermined thickness, and does not need to set up complex degree control, which can save costs to a certain extent.

Both can be achieved on one device, which can further improve the working efficiency of the device.

[0023] Furthermore, the servo motor on the device can not only achieve the effect of winding the steel strip body, but also the function of cutting the steel strip, and the two will not produce motion interference, and automatic switching can be achieved completely passively, which greatly improves the resource utilization of the equipment and is suitable for wide promotion and use.

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] See also Figure 1-15The present invention provides a technical solution: a precision steel strip winding and cutting integrated machine, comprising a frame 1 and a support frame 2 installed on the frame 1, a winding roller 4 for winding a steel strip body 3 is installed on the frame 1, a protective plate 7 is slidably connected to the frame 1, and the protective plate 7 is in contact with the steel strip body 3; a cutting knife 14 is vertically slidably connected to the frame 1, and a power unit 15 for driving the cutting knife 14 to slide vertically is provided on the frame 1; a servo motor 6 is provided on the frame 1, and the servo motor 6 drives the winding roller 4 to rotate through an intermittent connection mechanism, and the protective plate 7 is connected to the intermittent connection structure through a trigger mechanism 9, and the trigger mechanism 9 is connected to the power unit 15. An intermittent part 17 is arranged between the parts 15, and they are intermittently connected through the series part 17; the servo motor 6 drives the power part 15 to move through the synchronization part 20; when working, the servo motor 6 drives the winding roller 4 to rotate through the intermittent connection mechanism to wind up the steel strip body 3, and passively drives the protective plate 7 to slide as the thickness of the steel strip body increases. When the protective plate 7 slides, the intermittent connection mechanism is driven to disengage from the winding roller 4 through the trigger mechanism 9, and the series part 17 is also driven to connect with the power part 15 through the trigger mechanism 9, so that the servo motor 6 drives the cutting knife 14 to move downward through the power part 15 to cut the steel strip body 3.

[0043] Specifically, the precision steel strip winding and cutting machine includes a frame 1 and a support frame 2 installed on the frame 1. The frame 1 is of detachable design, specifically including a base and a side panel slidably connected to the base. When a roll of steel strip body 3 is wound, the side panel can be removed from the base, and the wound steel strip body 3 can be removed from the frame 1, which is convenient for the use of the entire equipment. A winding roller 4 for winding the steel strip body 3 is installed on the frame 1, and the winding roller 4 is detachably connected to the frame 1. There are many ways to install the winding roller 4 and the frame 1, which are technical means well known to those skilled in the art and will not be repeated here. A protective plate 7 is slidably connected to the frame 1, and the protective plate 7 is in contact with the steel strip body 3. Therefore, during the winding process, as the winding thickness of the steel strip body 3 increases, the protective plate 7 is passively driven to slide horizontally on the frame 1. Specifically, a slide groove is provided on a side of the frame 1 away from the side plate, wherein the protective plate 7 is slidably connected to the frame 1 through the extrusion unit 8, and will not hinder the disassembly of the frame 1 and the winding roller 4.

[0044] Among them, a cutting knife 14 is vertically slidably connected to the frame 1, and the cutting knife 14 is used for cutting the steel strip. And a power unit 15 for driving the cutting knife 14 to slide vertically is provided on the frame 1, which can provide power for the cutting knife 14 to slide downward to cut the steel strip body 3, and the use effect is better. Specifically, a servo motor 6 is provided on the frame 1, and the servo motor 6 drives the winding roller 4 to rotate through an intermittent connection mechanism. That is, the servo motor 6 only drives the winding roller 4 to rotate at a predetermined time. When it is not necessary to drive the winding roller 4 to rotate, the servo motor 6 will not drive the winding roller 4 to rotate through the intermittent connection mechanism at this moment, so as to meet the working needs. Among them, the protective plate 7 is connected to the intermittent connection structure through a trigger mechanism 9. Therefore, as the thickness of the steel strip body 3 gradually increases, the trigger mechanism 9 will be driven to move through the protective plate 7, which is convenient for subsequent operations. The trigger mechanism 9 is intermittently connected to the power unit 15 through the serial connection 17, and the servo motor 6 drives the power unit 15 to move through the synchronous member 20, that is, the servo motor 6 is always connected to the power unit 15 through the synchronous member 20. However, when the serial connection 17 is not in contact with the driving member, the servo motor 6 at this moment cannot drive the cutting knife 14 to slide downward through the power unit 15. On the contrary, when the serial connection 17 is connected to the power unit 15, the servo motor 6 at this moment will normally drive the cutting knife 14 to slide downward through the synchronous member 20 and the power unit 15 to cut the steel strip body 3. Therefore, the cutting knife 14 only slides downward within a predetermined time.

[0045] In the original state, the servo motor 6 is connected to the winding roller 4 through the intermittent connection mechanism. When the rotating shaft of the servo motor 6 rotates, it will drive the winding roller 4 to rotate to perform the winding operation. The series connection member 17 at this moment does not contact the power unit 15. Therefore, if the servo motor 6 works normally, the power unit 15 at this moment will not drive the cutting knife 14 to slide downward to cut the steel strip body 3.

[0046] During operation, the servo motor 6 drives the winding roller 4 to rotate through the intermittent connection mechanism to wind up the steel strip body 3. As the thickness of the steel strip body increases, the protective plate 7 is passively driven to slide. When the protective plate 7 slides, the intermittent connection mechanism is driven to disengage from the winding roller 4 through the trigger mechanism 9. The series connection 17 is also driven to connect with the power unit 15 through the trigger mechanism 9, so that the servo motor 6 drives the cutting knife 14 to move downward through the power unit 15 to cut the steel strip body 3. Therefore, in the actual operation process, as the winding roller 4 continues to wind up the steel strip body 3, the thickness of the steel strip body 3 will gradually increase. Since the protective plate 7 fits the steel strip body 3, when the thickness of the steel strip body 3 gradually increases, the protective plate 7 will be passively driven to slide. When the protective plate 7 slides a certain distance (that is, when the predetermined thickness of the steel strip body 3 is about to be reached), it will begin to contact the trigger mechanism 9. As the protective plate 7 slides, the trigger mechanism 9 will drive the intermittent connection mechanism to move, so that the power of the servo motor 6 is separated from the winding roller 4. At this moment, the winding roller 4 will stop rotating, so as to facilitate the later cutting of the steel strip body 3 on the winding roller 4. At the same time, when the winding roller 4 stops rotating, it is also convenient to remove the winding roller 4 from the frame 1, and the use effect is better. In the process of the trigger mechanism 9 driving the intermittent connection mechanism to separate from the winding roller 4, the trigger mechanism 9 also drives the series connection 17 to connect with the power unit 15, so that the servo motor 6 drives the cutting knife 14 to move downward through the power unit 15 to cut the steel strip body 3, and there is no need to set up a cutting mechanism separately to cut the steel strip body 3. Therefore, the device can passively stop the rotation of the winding roller 4 and stop the winding operation according to the requirements of the steel strip body 3 of a predetermined thickness, and does not need to set up complex degree control, which can save costs to a certain extent. At the same time, the servo motor 6 can be passively driven to connect with the driving part of the cutting knife 14 through the trigger mechanism 9, so that the servo motor 6 drives the cutting knife 14 to cut the steel strip body 3. Both can be achieved on one device, which can further improve the working efficiency of the device. At the same time, the servo motor 6 on the device can achieve the effect of winding the steel strip body 3 and the effect of cutting the steel strip, and the two will not produce motion interference, and the automatic switching is completely passive, which greatly improves the resource utilization rate of the equipment and is suitable for wide promotion and use.

[0047] In the embodiment provided by the present invention, the intermittent connection mechanism includes a driving rod 5. More specifically, the driving rod 5 and the frame 1 can be connected by a clamping connection, which is convenient for disassembly of the driving rod 5, and the servo motor 6 driving shaft drives the driving rod 5 to rotate. More specifically, the servo motor 6 driving shaft and the driving rod 5 are detachably connected, which is convenient for separation of the servo motor 6 driving shaft and the driving rod 5. A trigger rod 10 is slidably connected inside the driving rod 5. The trigger rod 10 and the driving rod 5 can only slide relative to each other, and the two cannot rotate relative to each other. An elastic member 12 is provided between the driving rod 5 and the trigger rod 10; and a clamping member 11 is provided between the trigger rod 10 and the winding roller 4. The clamping member 11 includes a clamping strip 11.1 fixedly connected to the trigger rod 10. Specifically, a cylinder is fixedly connected inside the winding roller 4, and a strip groove 11.2 is provided on the inner wall of the cylinder. The clamping strip 11.1 is slidably connected inside the strip groove 11.2, and the elastic force of the elastic member 12 drives the clamping strip 11.1 to clamp inside the strip groove 11.2. At this moment, when the servo motor 6 is started, it will drive the driving rod 5 to rotate and drive the trigger rod 10 to rotate. Since the clamping strip 11.1 is clamped in the strip groove 11.2, when the trigger rod 10 rotates, the winding roller 4 will be driven to rotate through the cooperation of the clamping strip 11.1 and the strip groove 11.2 to reel the steel strip body 3. When the clamping strip 11.1 slides out of the strip groove 11.2, when the trigger rod 10 rotates, it cannot drive the winding roller 4 to rotate.

[0048] In the embodiment provided by the present invention, the trigger mechanism 9 includes a first rack 9.1 mounted on the protective plate 7, and a transmission gear 9.3 is rotatably connected to the frame 1. Specifically, a support rod is fixedly connected to the frame 1, and the transmission gear 9.3 is rotatably connected to the support rod. A second rack 9.2 is also slidably connected to the frame 1, and the first rack 9.1 and the second rack 9.2 are respectively meshed on the upper and lower sides of the transmission gear 9.3. Specifically, a limited position unit is set between the first rack 9.1 and the second rack 9.2 and the bracket to improve the stability of the first rack 9.1 and the second rack 9.2 when sliding, so as to achieve better use effect. A driving block 9.4 is fixedly connected to the second rack 9.2, and a force block 9.5 is installed on the trigger rod 10 through a mounting plate. Specifically, the trigger rod 10 is rotatably connected to the mounting plate. When the trigger rod 10 rotates, the mounting plate and the force block 9.5 do not rotate. Specifically, the driving block 9.4 and the force block 9.5 are both wedge-shaped blocks, and the driving block 9.4 and the force block 9.5 are intermittently abutted. When the thickness of the steel belt body 3 gradually increases, it will passively drive the protective plate 7 to slide, which will drive the first rack 9.1 to slide, and the driving block 9.4 will slide through the cooperation of the first rack 9.1 and the second rack 9.2. After the driving block 9.4 abuts against the force block 9.5, as the driving block 9.4 continues to slide, it will drive the force block 9.5 to slide. When the force block 9.5 slides, it will drive the trigger rod 10 to slide through the mounting plate until the clamping strip 11.1 on the trigger rod 10 slides out of the strip groove 11.2 to meet the working needs.

[0049] In the embodiment provided by the present invention, an elastic cylinder 19 is installed on the frame 1, and a synchronous member 20 is arranged between the elastic cylinder 19 and the driving rod 5, wherein the synchronous member 20 is a technical means well known to those skilled in the art and will not be described in detail here. The power unit 15 includes a driving rack 15.1 fixedly connected to the cutting knife 14, and also includes a driving gear 15.2, the driving gear 15.2 is meshed with the driving rack 15.1, and the series member 17 is arranged between the elastic cylinder 19 and the driving gear 15.2, and the series member 17 includes a series block 17.1, the series block 17.1 is fixedly connected to the linkage rod 16, the linkage rod 16 is slidably connected in the elastic cylinder 19, and the linkage rod 16 and the elastic cylinder 19 can only slide relative to each other, and an adapting groove 17.2 adapted to the series block 17.1 is opened on the side wall of the driving gear 15.2, and the series block 17.1 is abutted and matched with the adapting groove 17.2; and the linkage rod 16 and the force block 9.5 are fixedly connected by a fixing rod 18. During use, when the series block 17.1 is not engaged in the adapter groove 17.2, when the servo motor 6 rotates, it can only drive the elastic tube 19 to rotate through the synchronous member 20, and cannot drive the linkage rod 16 to rotate through the elastic tube 19. When the thickness of the steel belt body 3 reaches a predetermined value, the force block 9.5 drives the trigger rod 10 to slide into the driving rod 5, so that the engaging strip 11.1 slides out of the strip groove 11.2. At this moment, when the servo motor 6 rotates, it cannot drive the winding drum to rotate. However, in the stroke in which the force block 9.5 drives the trigger rod 10 to slide into the driving rod 5, the fixing rod 18 drives the linkage rod 16 to slide into the elastic tube 19, so that the series block 17.1 slides into the adapting groove 17.2. Since the series block 17.1 and the adapting groove 17.2 are both conical, when the series block 17.1 is clamped in the adapting groove 17.2 and the clamping strip 11.1 on the trigger rod 10 completely slides out from the strip groove 11.2, the series block 17.1 at this moment is just completely clamped in the adapting groove 17.2, and there is enough friction to drive the driving gear 15.2 to rotate. When the driving gear 15.2 rotates, it will drive the driving rack 15.1 to slide downward, and finally the cutting knife 14 can be driven to slide downward through the driving rack 15.1 to cut the steel strip body 3, thereby greatly improving the use efficiency of the device. At the same time, a connecting frame is also provided on the top of the frame 1, wherein a driving ring is fixedly connected to the side wall of the driving gear 15.2, and an annular groove is provided on the connecting frame, wherein the driving ring is rotatably connected in the annular groove, thereby improving the stability of the driving gear 15.2 when rotating. Specifically, a limiting portion is also provided between the cutting knife 14 and the frame 1 to improve the stability of the cutting knife 14 when cutting downward, and the use effect is better. At the same time, a cutting groove is provided on the support frame 2, which can better perform the cutting operation.

[0050] In the embodiment provided by the present invention, a positioning frame 13 is further provided on the frame 1, a positioning plate 21 is installed inside the positioning frame 13, and multiple groups of strong springs 22 are provided between the positioning plate 21 and the positioning frame 13, and the elastic force of the strong springs 22 drives the positioning plate 21 to abut against the steel strip body 3, that is, after the cutting knife 14 completes the cutting of the steel strip body 3, the strong springs 22 drive the positioning plate 21 to slide downward and abut against the steel strip body 3, and position the outermost steel strip body 3 after the winding, so as to avoid the tension of the steel strip body 3, which causes the steel strip body 3 to loosen, and facilitates the bundling operation of the steel strip body 3, and the use effect is better. When the power unit 15 drives the cutting knife 14 to slide downward to cut the steel strip body 3, the positioning plate 21 positions the steel strip body 3 to meet the working needs.

[0051] In the embodiment provided by the present invention, a locking member 23 is provided between the positioning plate 21 and the positioning frame 13, and the locking member 23 fixes the positioning plate 21 inside the positioning frame 13, so as to avoid the positioning plate 21 being exposed when not in use, thereby meeting the working requirements.

[0052] In the embodiment provided by the present invention, an unlocking portion 24 is provided between the cutting knife 14 and the locking rod 23.1. When the power unit 15 drives the cutting knife 14 to slide downward to cut the steel strip body 3, the positioning plate 21 is unlocked by the unlocking portion 24; the unlocking portion 24 includes an unlocking rod 24.1 fixedly connected to the cutting knife 14, and an unlocking groove 24.2 is provided on the locking rod 23.1, and the unlocking rod 24.1 intermittently abuts against the unlocking groove 24.2. 2, so that the locking bar 23.1 can be easily released from the locking groove 23.2, and the locking bar 23.1 can be easily released from the locking groove 23. ...

[0053] In the embodiment provided by the present invention, a reset rod 25 is fixedly connected to the positioning plate 21, and the reset rod 25 is slidably connected to the positioning frame 13. Specifically, a wedge-shaped surface is provided at the bottom of the locking rod 23.1, so that the positioning plate 21 can drive the locking rod 23.1 to slide in the opposite direction, so that the locking rod 23.1 can be easily engaged in the locking groove 23.2 again. Therefore, after use, the reset rod 25 is driven upward to slide, and after overcoming the elastic force of the strong spring 22, the locking rod 23.1 is driven to be close to the locking groove 23.2, and the positioning plate 21 is fixed again, which is convenient for the next use.

[0054] In the embodiment provided by the present invention, the protective plate 7 is slidably connected to the frame 1 through an extrusion unit 8; the extrusion unit 8 includes a mounting block 8.1 fixedly connected to the protective plate 7, and a pressure spring 8.2 is arranged between the mounting block 8.1 and the frame 1, so that the elastic force of the pressure spring 8.2 can make the protective plate 7 tightly attached to the steel belt body 3, and can exert pressure on the steel belt body 3 to a certain extent, which can improve the compactness of the winding of the steel belt body 3.

[0055] Working principle: When using the precision steel strip winding and cutting machine, firstly, the steel strip body 3 is wound on the winding roller 4, and then the servo motor 6 is started. The servo motor 6 drives the winding roller 4 to rotate through the cooperation between the intermittent connection mechanisms to perform the winding operation on the steel strip body 3. As the winding roller 4 continues to wind the steel strip body 3, the thickness of the steel strip body 3 will gradually increase. Since the protective plate 7 fits the steel strip body 3, when the thickness of the steel strip body 3 gradually increases, the protective plate 7 will be passively driven to slide. When the protective plate 7 slides, it will drive the first rack 9.1 to slide, and the cooperation of the first rack 9.1 and the second rack 9.2 will drive the driving block 9.4 to slide. When the driving block 9.4 abuts against the force block 9.5, as the driving block 9.4 continues to slide, it will drive the force block 9.5 to slide. When the force block 9.5 slides, it will drive the trigger rod 10 to slide through the mounting plate until the clamping strip 11.1 on the trigger rod 10 slides out of the strip groove 11.2, at which time the winding roller 4 stops rotating.

[0056] During the stroke in which the force block 9.5 drives the trigger rod 10 to slide inside the driving rod 5, the fixing rod 18 drives the linkage rod 16 to slide inside the elastic tube 19, so that the series block 17.1 slides inside the adapting groove 17.2. Since the series block 17.1 and the adapting groove 17.2 are both conical, when the series block 17.1 is clamped in the adapting groove 17.2 and the clamping strip 11.1 on the trigger rod 10 completely slides out from the strip groove 11.2, the series block 17.1 at this moment is just completely clamped in the adapting groove 17.2, and there is enough friction to drive the driving gear 15.2 to rotate. When the driving gear 15.2 rotates, it will drive the driving rack 15.1 to slide downward, and finally the cutting knife 14 can be driven to slide downward through the driving rack 15.1 to cut the steel strip body 3, thereby greatly improving the use efficiency of the device.

[0057] 2, so that the locking bar 23.1 can be easily released and the locking bar 23.2 can be easily released.
