Description

Technical Field

[0001] This invention relates to the field of building material production technology, specifically to a cutting device for hollow brick production. Background Technology

[0002] With the advancement of environmental protection policies and the increasing demand for resource recycling, the technology of producing hollow bricks for construction using recycled resin-based composite materials has received widespread attention. These hollow bricks combine the advantages of being lightweight and high-strength, fire-retardant, and having a long service life. They also can absorb a large amount of waste composite materials, exhibiting significant economic and environmental value. In the hollow brick production process, the cutting process is a crucial step determining the quality of the finished product. Considering the characteristics of recycled resin-based composite material blanks, the industry widely adopts wire cutting technology, which has the advantages of simple structure, low maintenance costs, and minimal damage to the blanks.

[0003] In current hollow brick production cutting devices, debris easily adheres to the surface of the steel wire. During the next cutting, the debris is easily squeezed and embedded in the cross-section of the brick blank, forming appearance defects such as pits and dents. Furthermore, the debris increases the frictional resistance between the steel wire and the blank, accelerating the wear and fatigue fracture of the steel wire, increasing the cost of equipment consumables and the frequency of downtime maintenance.

[0004] To address the above problems, a cutting device for hollow brick production is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a cutting device for hollow brick production. By using this device, the problem in the background mentioned above is that the steel wire surface is prone to adhering with debris, and the debris is easily squeezed and embedded into the cross-section of the brick blank during the next cutting, forming appearance defects such as pits and dents.

An elastic piston is slidably connected inside the air-jet cleaning members and is rotatably connected to the concave plate.

[0007] Furthermore, three limiting rods are installed at the top of the concave plate, and the scraper is slidably connected to the limiting rods. Several friction rings are installed on both sides of the concave plate, and the steel wire is slidably connected to the friction rings.

[0008] Furthermore, the winding component includes a fixed plate and a motor fixed inside the fixed plate. A number of first fixed frames are correspondingly arranged on one side of the concave plate. A rotating shaft is fixedly installed at the output end of the motor.

[0009] Furthermore, the release component includes several second fixing frames correspondingly installed on one side of the concave plate, a rotating roller is rotatably connected between two second fixing frames, a rotating rod is fixedly installed inside the rotating roller, and a gear disk is installed on the surface of the rotating rod.

[0010] Furthermore, the clamping member includes a housing and a toothed plate slidably connected inside the housing, and the toothed plate engages with the gear disk. A second electromagnet is fixedly installed inside the housing, a second magnet block is fixedly installed on one side of the toothed plate, and two first springs are fixedly installed on one side of the toothed plate, with one end of each of the two first springs fixedly connected to the housing.

[0011] Furthermore, two first magnet blocks are fixedly installed on both sides of the concave plate. The scraping component includes a cleaning plate and two third magnet blocks fixed on both sides of the cleaning plate. The third magnet blocks attract the first magnet blocks. A ring frame is fixedly installed on both sides of the cleaning plate. A fourth magnet block is fixedly installed inside the ring frame. Three limiting blocks are fixedly installed on one side of the cleaning plate. The three limiting blocks are slidably connected to the three limiting rods and the concave plate. Several through holes are opened through one side of the cleaning plate. The through holes are slidably connected to the surface of the steel wire.

[0012] Furthermore, the collecting component includes a collecting shell and sliders fixed at both ends of the collecting shell. Both sliders are slidably connected to the cleaning plate. An arc-shaped block is slidably connected to one side of the slider, and the arc-shaped block is slidably connected to the arc-shaped groove inside the cleaning plate. A second spring is fixedly installed at one end of the arc-shaped block, and one end of the second spring is fixedly connected to the slider.

[0013] Furthermore, several threaded grooves are provided on both sides of the concave plate. The air jet cleaning component includes a slide cylinder and several balls rotatably mounted on the surface of the slide cylinder, and the balls are in contact with the threaded grooves. Several trapezoidal scraping frames are evenly installed on one end of the slide cylinder. A connecting shell is connected to one side of the trapezoidal scraping frame, and the connecting shell is connected through to one end of the slide cylinder. Several air outlets are provided through one side of the trapezoidal scraping frame.

[0014] Furthermore, a filter screen is installed inside the air outlet.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The winding and releasing components work together to maintain the wire tautness in real time, avoiding cutting trajectory deviation caused by insufficient tension. The automatic replacement design of worn sections prevents defects such as burrs on the cross-section and incomplete cutting of ribs caused by wire wear.

[0017] 2. The scraper slides on the surface of the steel wire, and during the movement, it can scrape off most of the debris attached to the surface of the steel wire, avoiding increased cutting resistance caused by debris adhesion, reducing steel wire wear, and preventing debris from being squeezed into the cross-section of the brick blank to form defects such as pits and dents.

[0018] 3. It adopts a four-stage cleaning solution of physical scraping, vibration descaling, rotary scraping and air blowing, which can remove debris from the surface and contact area of ​​the steel wire. The cleaning power comes entirely from the moving and squeezing of the scraping parts, eliminating the need for an independent air pump and blower, thus reducing the overall energy consumption of the equipment.

[0019] 4. The collection device can efficiently collect the debris that falls off during the cleaning process. The recovered debris can be directly mixed back into the hollow brick blank, replacing some of the new raw materials, reducing the amount of solid waste landfill, reducing resource waste, and preventing debris from falling into different areas, which can achieve the effect of environmental protection.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] To address the technical problem that steel wire 7 easily accumulates debris, which can become embedded in the brick blank cross-section during subsequent cutting, causing surface defects such as pits and dents, and accelerating wear and fatigue fracture of the steel wire 7, such as… Figures 1-12 As shown, the following preferred technical solutions are provided: like Figures 1-4As shown, a cutting device for hollow brick production includes a press 1 and a placement plate 2 fixed to the surface of the press 1. The placement plate 2 provides a stable support plane for the blank strips, ensuring synchronous contact with the blank strip surface during cutting, achieving multi-piece cutting at one time. Compared with the single-piece cutting mode, the cutting efficiency is improved. A concave plate 3 is fixedly installed at the output end of the press 1. The press 1, as the power output core, drives the concave plate 3 to press down vertically, which can precisely control the cutting pressure and pressing speed, and is suitable for recycled resin-based composite material blank strips of different hardness. Low pressure and low speed are used for soft billets to avoid deformation due to compression, while medium pressure and medium speed are used for hard billets to ensure cutting efficiency and improve the adaptability of billet cutting. A winding component 4 is fixedly installed on one side of the concave plate 3, and a release component 5 and a clamping component 6 are installed on the other side of the concave plate 3. The clamping component 6 is engaged with the release component 5. Several steel wires 7 are slidably connected inside the concave plate 3. The design of multiple steel wires 7 arranged in parallel can cut the billet into multiple brick blanks of the same size at one time, reducing repeated cutting processes and reducing energy consumption per unit product.

[0024] Furthermore, one end of the steel wire 7 is wound around the surface of the take-up member 4, and the other end is wound around the surface of the release member 5. The take-up member 4 and the release member 5 cooperate to perform small-scale take-up and release of the steel wire 7 in real time, always maintaining the steel wire 7 in a taut state, avoiding the deviation of the cutting trajectory caused by the slack of the steel wire 7, and ensuring cutting accuracy. The snap-fit ​​design of the clamping member 6 and the release member 5 can realize the quick replacement of the worn section of the steel wire 7. After the snap-fit ​​is released, the take-up member 4 will take back the worn section of the steel wire 7, and the release member 5 will simultaneously release a new section of steel wire 7. The wire 7 is replaced and re-clamped to prevent the entire wire 7 from being scrapped due to local wear. The first electromagnet 8 is installed on both sides of the concave plate 3. The scraper 9 is slidably connected inside the concave plate 3 and is slidably connected to the surface of the wire 7. During the movement, most of the debris attached to the surface of the wire 7 can be scraped off, avoiding the increase in cutting resistance caused by debris adhesion, reducing the wear of the wire 7, and preventing debris from being squeezed into the cross-section of the brick blank to form defects such as pits and depressions.

[0025] Several collection components 10 are slidably engaged on one side of the scraper 9. The collection components 10 can collect the scraped debris in real time, preventing the debris from spreading to the workshop environment and causing pollution. The collection components 10 are easy to disassemble, and the cleaned debris can be directly mixed back into the billet, realizing closed-loop resource utilization and reducing the amount of solid waste landfill. Several air-jet cleaning components 20 are threadedly connected to both sides of the concave plate 3, and the steel wire 7 is slidably connected to the air-jet cleaning components 20. The air-jet cleaning components 20 use the squeezing force of the scraper 9 to rotate. During the rotation, they can scrape the contact position between the scraper 9 and the steel wire 7 to remove the residual debris at the contact position, solving the problem that the single scraper affects the debris removal effect. An elastic piston component 30 is slidably connected inside the air-jet cleaning component 20, and the elastic piston component 30 is rotatably connected to the concave plate 3. When the air-jet cleaning component 20 rotates, it moves towards the concave plate 3. The plate 3 moves internally, squeezing the elastic piston 30 to generate airflow. The airflow is ejected from the inner wall of the jet cleaning component 20, sweeping the contact area between the scraper 9 and the steel wire 7 to further remove fine residual debris. The gas ejected from the jet cleaning component 20 is used to assist in cleaning, blowing away debris at the end of the jet cleaning component 20. Under the action of gravity, most of the debris falls into the collection component 10. The cleaning effect is greatly improved compared to traditional single scraping, ensuring stable subsequent cutting quality. The power of the entire jet cleaning process comes from the movement and squeezing of the scraper 9. There is no need to configure independent air pumps and blowers, achieving self-sufficiency in cleaning power and further reducing the total energy consumption of the equipment. When the scraper 9 separates from the jet cleaning component 20, the elasticity of the elastic piston 30 can push the jet cleaning component 20 to reset, reserving power for the next jet cleaning.

[0026] The hollow brick blank is placed stably on the surface of the placement plate 2. The relative position of the blank and the steel wire 7 is confirmed according to the preset size of the brick blank to ensure accurate cutting trajectory. The press 1 is started through the controller (the controller is existing technology and is not shown in the figure). The output end of the press 1 drives the concave plate 3 to move vertically downward. Several steel wires 7 arranged in parallel inside the concave plate 3 simultaneously contact the surface of the blank. Relying on the downward pressure output by the press 1, the shearing force of the steel wire 7 is used to cut the continuous blank into several hollow brick blanks of the same size in one go. The parallel design of multiple steel wires 7 can complete multiple cutting processes at the same time, which greatly improves the efficiency of single block cutting. After the block cutting is completed, the press 1 drives the concave plate 3 to return to the initial position. The operator takes out the cut brick blanks and prepares for the next round of cutting. When it is observed that the steel wire 7 has become slightly loose due to long-term cutting, the winding device 4 is started to perform a small winding, pulling the steel wire 7 to tighten synchronously, ensuring that the cut section of steel wire 7 inside the concave plate 3 always remains taut, avoiding the deviation of the cutting trajectory and unevenness of the brick blank cross-section due to insufficient tension.

[0027] When the cutting section of wire 7 wears or undergoes plastic deformation after prolonged use, the controller disengages the clamping member 6 from the releasing member 5. Then, the winding member 4 starts, winding up all the worn section of wire 7 within the concave plate 3. Simultaneously, the releasing member 5 releases the replacement section of wire 7. After the replacement section completely replaces the worn section, the clamping member 6 and the releasing member 5 re-clamp and secure themselves, restoring the cutting tension of wire 7 and ensuring stable subsequent cutting results. After each block cutting is completed, the controller activates the first electromagnet 8 inside the concave plate 3. Initially, the scraper 9 and... The inner side of the concave plate 3 is tightly fitted. When the first electromagnet 8 is energized, it generates a repulsive force, which pushes the scraper 9 to slide along the inside of the concave plate 3. The scraper 9 is slidably connected to the surface of the steel wire 7. During the movement, it can scrape off the debris attached to the surface of the steel wire 7. The scraped debris falls directly into the collection piece 10 that is slidably engaged below the scraper 9 for temporary storage. When the scraper 9 slides from one side of the concave plate 3 to the other side, the scraper 9 collides with the air jet cleaning piece 20. The vibration force generated by the collision can cause the debris remaining at the contact position between the scraper 9 and the steel wire 7 to fall off and fall into the collection piece 10.

[0028] Simultaneously, the first electromagnet 8 continuously outputs repulsive force to rapidly push the scraper 9 to squeeze the air-jet cleaning component 20. Since the air-jet cleaning component 20 is threadedly connected to the concave plate 3, the squeezing force drives it to rotate around the threaded axis. During rotation, one end of the air-jet cleaning component 20 scrapes the contact point between the scraper 9 and the steel wire 7, further removing residual debris. As the air-jet cleaning component 20 rotates, it moves inward into the concave plate 3, squeezing the elastic piston 30 inside. Under pressure, the elastic piston 30 ejects air from inside the air-jet cleaning component 20. Combined with the rotation of the air-jet cleaning component 20, this better blows residual fine debris into the collecting component 10. This repeated process improves the cleaning effect, and the entire cleaning process requires no additional... The dust removal fan is configured and operates entirely by the moving drive of the scraper 9. After the debris in the collection piece 10 accumulates to a certain amount, the operator can remove the collection piece 10 from the scraper 9 and directly mix the recovered debris back into the hollow brick blank to replace part of the new raw material, thus achieving closed-loop utilization of resources. Therefore, the cooperation between the winding piece 4 and the releasing piece 5 can maintain the tension of the steel wire 7 in real time, avoiding dimensional deviations caused by slack. The automatic replacement design of the wear section can prevent defects such as burrs on the cross-section and incomplete cutting of the ribs caused by the wear of the steel wire 7. Secondly, through the four cleaning mechanisms of physical scraping, vibration chip removal, rotation scraping and air jet cleaning, the debris on the surface and contact position of the steel wire 7 can be removed, preventing the debris from being squeezed and embedded in the cross-section of the brick blank to form pits and dents, thereby improving the finished product qualification rate.

[0029] like Figure 5 and Figure 11As shown, two first magnet blocks 31 are fixedly installed on both sides of the concave plate 3. In the initial state, the first magnet blocks 31 can magnetically attract the scraper 9 to the inside of the concave plate 3, preventing the scraper 9 from shifting when the device is not working and preventing the elastic force of the elastic piston 30 from pushing the scraper 9 to move. When the scraper 9 is not in use, it is stable inside the concave plate 3. Three limiting rods 32 are installed at the top inside the concave plate 3, and the scraper 9 is slidably connected to the limiting rods 32. Several friction rings 33 are installed on both sides of the concave plate 3, and the steel wire 7 is slidably connected to the friction rings 33. The friction of the friction rings 33 can prevent the steel wire 7 from loosening when it is released. Several threaded grooves 34 are opened on both sides inside the concave plate 3. The scraper 9 is slidably connected to the limiting rods 32, which can strictly limit the offset of the scraper 9 and ensure that the scraper 9 is always in close contact with the surface of the steel wire 7 during the movement, avoiding the problem of local missed scraping or incomplete scraping caused by the shaking of the scraper 9.

[0030] like Figures 9-10 As shown, the scraping component 9 includes a cleaning plate 91 and two third magnet blocks 92 fixed on both sides of the cleaning plate 91. The third magnet blocks 92 and the first magnet blocks 31 attract each other. When the third magnet blocks 92 and the first magnet blocks 31 inside the concave plate 3 attract each other, the cleaning plate 91 can be stably adsorbed in the initial position inside the concave plate 3 in the non-cleaning state, avoiding the vibration of the device during operation that causes the cleaning plate 91 to shift. At the same time, the attraction between the third magnet blocks 92 and the first magnet blocks 31 is greater than the spring force of the elastic piston component 30 for resetting, preventing the spring force of resetting from pushing the cleaning plate 91 to displacement, ensuring that the starting position of each cleaning action is consistent, and ensuring the accuracy of the cleaning trajectory. Ring frames 93 are fixedly installed on both sides of the cleaning plate 91, and fourth magnet blocks 94 are fixedly installed inside the ring frames 93. During cleaning, the first electromagnet 8 is energized to generate repulsion. The force pushes the fourth magnet block 94, thereby pushing the cleaning plate 91 to clean the debris attached to the surface of the steel wire 7. Three limiting blocks 95 are fixedly installed on one side of the cleaning plate 91, and the three limiting blocks 95 are slidably connected to the three limiting rods 32 and the concave plate 3. Several through holes 96 are opened through one side of the cleaning plate 91, and the through holes 96 are slidably connected to the surface of the steel wire 7. The through hole 96 is designed to be through and slidably connected to the surface of the steel wire 7. When the cleaning plate 91 moves, the inner wall of the through hole 96 can scrape the surface of the steel wire 7 in 360° all-round way. Compared with the traditional one-sided scraping, it can more efficiently remove the debris attached to the surface of the steel wire 7, improve the cleaning efficiency. The inner wall of the through hole 96 can be made of wear-resistant rubber or polyurethane material. When scraping, it can remove debris and avoid scratching the surface of the steel wire 7, reduce the wear of the steel wire 7, and extend the service life of the steel wire 7.

[0031] like Figure 10As shown, the collection component 10 includes a collection shell 101 and sliders 102 fixed at both ends of the collection shell 101. Both sliders 102 are slidably connected to the cleaning plate 91. An arc-shaped block 103 is slidably connected to one side of each slider 102, and the arc-shaped block 103 is slidably connected to the arc-shaped groove inside the cleaning plate 91. A second spring 104 is fixedly installed at one end of the arc-shaped block 103, and one end of the second spring 104 is fixedly connected to the slider 102. During installation, the sliders 102 at both ends of the collection shell 101 are aligned with the grooves on the cleaning plate 91, and the collection shell 101 is pushed inward along the grooves. During the pushing process, the arc-shaped block 103 inside the slider 102 is squeezed by the arc-shaped groove inside the cleaning plate 91, and moves towards the slider. The inner side of 102 contracts and compresses the second spring 104. When the slider 102 slides to the preset position of the groove, the elastic force of the second spring 104 pushes the arc block 103 to reset, so that it is locked into the arc groove of the cleaning plate 91, realizing the sliding engagement and locking of the collection shell 101 and the cleaning plate 91, preventing the collection shell 101 from falling off during the movement of the cleaning plate 91. When the cleaning plate 91 slides to scrape off the debris on the surface of the steel wire 7, the debris peeled off from the steel wire 7 will fall off under the action of gravity. The collection shell 101 is located below the cleaning plate 91 and extends to both sides of the cleaning plate 91, so it is always on the debris falling path and can receive most of the scraped debris in real time, preventing debris from falling and contaminating the workshop.

[0032] like Figures 11-12 As shown, the jet cleaning component 20 includes a slide cylinder 201 and several balls 202 rotatably mounted on the surface of the slide cylinder 201. The balls 202 are in contact with the threaded groove 34, and there is rolling friction between the balls 202 and the threaded groove 34, which reduces frictional resistance. When the cleaning plate 91 squeezes the slide cylinder 201, the slide cylinder 201 can quickly rotate along the threaded groove 34 and move into the concave plate 3, avoiding problems such as insufficient squeezing of the elastic piston component 30 and insufficient jet pressure caused by friction jamming, thus ensuring the timeliness of the deep cleaning action. Several trapezoidal scraper frames 20 are evenly installed at one end of the slide cylinder 201. 3. A connecting shell 204 is connected to one side of the trapezoidal scraper frame 203, and the connecting shell 204 is connected to one end of the slide cylinder 201. The connecting shell 204 can evenly deliver the airflow generated by the elastic piston 30 to the interior of each trapezoidal scraper frame 203, so that the airflow is ejected from the trapezoidal scraper frame 203, forming a synergistic cleaning mechanism of scraping and air jetting. Several air outlets 205 are opened through one side of the trapezoidal scraper frame 203. The high-pressure airflow delivered by the connecting shell 204 can be blown directly to the contact position between the cleaning plate 91 and the steel wire 7 through the air outlets 205, forming a dual cleaning effect of scraping and peeling and airflow blowing.

[0033] A filter screen 206 is installed inside the air outlet 205. The filter screen 206 can prevent debris from entering the connecting shell 204 and the slide 201, avoid blockage of the air jet channel due to debris accumulation, and ensure smooth airflow and pressure stability during each cleaning.

[0034] like Figure 11 As shown, the elastic piston component 30 includes an annular plate 301 and a limiting ring 302 fixed to one side of the annular plate 301. The limiting ring 302 is rotatably connected to the concave plate 3. Several support rods 303 are fixedly installed on one side of the annular plate 301, and the support rods 303 are slidably connected to the slide cylinder 201. A piston plate 304 is slidably connected inside the slide cylinder 201, and the support rods 303 are fixedly connected to the piston plate 304. A third spring 306 is fixedly installed on one side of the annular plate 301, and one end of the third spring 306 is fixedly connected to the slide cylinder 201. When the cleaning plate 91 slides to contact the trapezoidal scraper frame 203, the continuous repulsive force quickly pushes the slide cylinder 201. Since the slide cylinder 201 and the threaded groove 34 of the concave plate 3 are connected by ball bearings 202, the extrusion force drives the slide cylinder 201 to rotate along the threaded groove 34 and move into the concave plate 3. During the movement of the slide cylinder 201, the piston plate 304 inside is limited by the support rod 303, and the annular plate 301 is rotatably connected to the concave plate 3 through the limiting ring 302. Therefore, when the slide cylinder 201 rotates, it will drive the annular plate 301 to rotate. The cavity volume between the inner wall of the slide cylinder 201 and the piston plate 304 continuously shrinks, and the air in the cavity is rapidly compressed to form a high-pressure airflow. The high-pressure airflow is transported to the trapezoidal scraper frame 203 through the connecting shell 204, and finally sprayed out directionally from the air outlet 205 to blow away the contact position between the cleaning plate 91 and the steel wire 7 and remove residual debris. When the cleaning operation is completed, when the squeezing force of the cleaning plate 91 on the slide cylinder 201 disappears, the third spring 306 on one side of the annular plate 301 releases elastic potential energy, pushing the slide cylinder 201 to rotate in the opposite direction along the threaded groove 34 and reset outward.

[0035] To address the technical problem of slight loosening and wear of steel wire 7 due to prolonged cutting, leading to cutting trajectory deviation and uneven brick cross-section, such as... Figures 5-8 As shown, the following preferred technical solutions are provided: like Figure 5 As shown, the winding component 4 includes a fixed plate 41 and a motor 42 fixed inside the fixed plate 41. Several first fixed frames 43 are correspondingly arranged on one side of the concave plate 3. A rotating shaft 44 is fixedly installed at the output end of the motor 42. A winding roller 45 is fixedly installed on the surface of the rotating shaft 44, and the winding roller 45 is rotatably connected to the first fixed frame 43. When the steel wire 7 becomes slightly loose due to long-term cutting, the controller triggers the motor 42 to start. The output end of the motor 42 drives the rotating shaft 44 to rotate at a low speed in the first fixed frame 43, which drives the coaxially connected winding roller 45 to rotate synchronously. When the winding roller 45 rotates, it slightly winds up the steel wire 7 wrapped on its surface, so that the cut section of steel wire 7 in the concave plate 3 always remains taut, avoiding deviation of the cutting trajectory due to insufficient tension.

[0036] When the cutting section of wire 7 shows obvious wear and plastic deformation, affecting the cutting quality, the controller first controls the clamping part 6 to disengage from the release part 5, so that the wire 7 at the end of the release part 5 is in a free release state. The motor 42 drives the take-up roller 45 to rotate at high speed, and winds all the worn section of wire 7 in the concave plate 3 around the surface of the first take-up roller 45. At the same time, the release part 5 releases the replacement section of wire 7 until the replacement section of wire 7 completely replaces the worn section and fills the cutting position of the concave plate 3. After the replacement section of wire 7 is in place, the clamping part 6 and the release part 5 are re-clamped and fixed, the motor 42 stops working, and the take-up roller 45 remains locked to ensure that the replacement section of wire 7 maintains stable tension and enters the next round of cutting operation. The automatic winding and replacement design of the worn section can divide the entire wire 7 into multiple cutting sections for sequential use, avoiding the scrapping of the entire wire 7 due to local wear, extending the overall service life of the wire 7, and significantly reducing the procurement and replacement cost of wire 7.

[0037] like Figures 6-8 As shown, the release component 5 includes several second fixing frames 51 correspondingly installed on one side of the concave plate 3. A rotating roller 52 is rotatably connected between two second fixing frames 51. The two second fixing frames 51 are symmetrically installed on one side of the concave plate 3, forming radial limits at both ends of the rotating roller 52 to ensure that the rotating roller 52 always rotates along the axis, avoiding the skewed release trajectory of the steel wire 7 due to rotational deviation, ensuring uniform tension of each steel wire 7, and avoiding the problem of tilted brick cross-section and uneven size caused by tension deviation of some steel wires 7 during cutting. A rotating rod 54 is fixedly installed inside the rotating roller 52, and a gear disk 55 is installed on the surface of the rotating rod 54. The gear disk 55 can form a precise locking position with the clamping component 6. When it is necessary to lock the tension of the steel wire 7, the clamping component 6 engages with the tooth groove of the gear disk 55, using the self-locking characteristic of the gear to restrict the rotation of the rotating roller 52, preventing the steel wire 7 from releasing itself and causing a decrease in tension. When it is necessary to change the section, the clamping component 6 is disengaged from the gear disk 55, and the rotating roller 52 can rotate freely to release the steel wire 7 to replace the section.

[0038] like Figure 8As shown, the clamping member 6 includes a housing 61 and a toothed plate 62 slidably connected inside the housing 61, and the toothed plate 62 engages with the gear disk 55. A second electromagnet 63 is fixedly installed inside the housing 61. A second magnet block 64 is fixedly installed on one side of the toothed plate 62. Two first springs 65 are fixedly installed on one side of the toothed plate 62, and one end of each of the two first springs 65 is fixedly connected to the housing 61. In the initial state, the second electromagnet 63 is de-energized, and the two first springs 65 inside the housing 61 are in a naturally extended state. The elastic force of the first springs 65 pushes the toothed plate 62 to slide towards the gear disk 55, so that the end of the toothed plate 62 engages with the gear disk 55. With precise meshing of the gear teeth, the rotational freedom of the gear disk 55 is restricted after meshing, preventing it from driving the rotating roller 52 to rotate. At this time, the rotating roller 52 is in a locked state. When the tension is finely adjusted by small-scale winding, the rotational torque generated by the steel wire 7 pulling the rotating roller 52 will be canceled by the toothed plate 62, ensuring that the steel wire 7 always maintains a stable tension to meet the cutting accuracy requirements. When it is necessary to replace the worn section of the steel wire 7, the second electromagnet 63 is energized, which can attract the second magnet block 64 to separate the gear disk 55 from the gear disk 55. The gear disk 55 is unlocked and its rotational freedom is restored. At this time, the rotating roller 52 can rotate freely with the winding action of the winding component 4, releasing the replacement section of the steel wire 7.
