Description

Technical Field

[0001] The invention relates to the technical field of concrete blocks, in particular to a production device for blocks. Background Art

[0002] As is known, blocks are man-made blocks made of concrete, industrial waste (such as slag and fly ash, etc.) or local materials. The production process of blocks is as follows: (1) Raw material preparation: fly ash or sand is ball-milled into a slurry of a certain concentration; (2) Crushing: lime raw materials are crushed by a crusher, and the crushed lime is then transported to a ball mill for grinding to obtain powder; (3) Mixing and pouring: The slurry, powder and other raw materials are measured, and the measured slurry and powder are then transported to a mixer for mixing to obtain a mixed material. Mix the mixed slurry evenly and then pour the mixed slurry into the mold frame; (4) Static curing: The mixed slurry poured into the mold frame is cured at a constant temperature for 2 to 3 hours to form a green body; (5) Cutting: When the green body reaches the cutting strength, the green body is demolded and then cut by a wire cutter. During cutting, the wire swings like a saw to complete the cutting of the green body and obtain a semi-finished green body; (6) Autoclave treatment: The semi-finished green body is transported to a steam curing kettle by a steam curing car and steam-cured for 8 to 10 hours, and then the finished blocks are taken out from the steam curing kettle.

[0003] When the steel wire cutting machine is cutting the blank, the steel wire is pressed into the blank from top to bottom through the reciprocating swinging steel wire, so that the steel wire cuts the blank into blanks that meet certain specifications, thereby realizing the cutting of blocks.

[0004] For example, the invention patent application entitled "A device for producing concrete blocks" with announcement number CN111844469A and announcement date October 30, 2020, is a device for producing concrete blocks, including a block production device body, a supporting chassis, a supporting cross plate, and a pneumatic cavity column, wherein the middle portion of the top surface of the supporting chassis is fixedly connected to the bottom surface of the supporting column, and the bottom end of the supporting chassis is provided with a plurality of supporting angles, and a slide groove is provided on the side of the upper half of the supporting column, and the slide groove is slidably connected to a slider fixedly provided on the back of the supporting cross plate. The concrete block production device of the invention realizes multi-directional movement of the block cutting knife position by setting a supporting chassis, a supporting column, and a supporting cross plate to build a simple and practical structural frame, a sliding structure of the supporting cross plate and the supporting column, and a rotating structure of the rotating disk and the supporting cross plate, and has a simple structure and strong practicality. In addition, a reflux valve and a reflux hose are provided to realize the circulation between steam and water.

[0005] The disadvantage of the prior art is that the two ends of the steel wire are clamped by the clamping unit. When the steel wire cuts the blank, the two clamping units drive the steel wire to perform a linear reciprocating motion. Since the steel wire performs a linear reciprocating motion on the blank, the steel wire has a certain amount of wear and tear, and the steel wire needs to be replaced regularly. When replacing the steel wire, the clamping unit needs to loosen the steel wire, and then the staff takes the steel wire out of the clamping unit, and then clamps the two ends of the new steel wire through the two clamping units. This is troublesome to replace the steel wire, and the number of steel wires is large, and the time required for replacing the steel wire is long, which affects the production efficiency of the blocks. In addition, since the connecting part of the steel wire end does not contact the blank when the steel wire performs a reciprocating linear motion to cut the blank, the wear on the steel wire end is small. Such replacement causes waste of steel wire material, thereby increasing the production cost of the blocks. Summary of the invention

[0037] In order to enable those skilled in the art to better understand the technical solution of the present invention, Figure 1 To Attachment Fig.16 The present invention is further described in detail.

[0038] An embodiment provided by the present invention relates to a production device for building blocks, comprising a frame 1, a clamping unit and a steel wire 4 for cutting, wherein two clamping units capable of synchronous reciprocating motion are symmetrically arranged at both ends of the frame, and the frame also comprises a replacement unit, wherein the replacement unit comprises a unwinding roller 2 and a winding roller 3, wherein the unwinding roller 2 is rotatably arranged at one end of the frame 1, and the winding roller 3 is arranged at the other end of the frame 1, the steel wire 4 is wound on the unwinding roller 2, and the winding roller 3 is connected to the end of the steel wire 4 on the unwinding roller 2, the two clamping units respectively clamp the two ends of the steel wire 4 between the winding roller 3 and the unwinding roller 2, and the steel wire 4 is driven by the clamping unit to perform a linear reciprocating motion to cut the blank.

[0039] Specifically, the frame 1 is a U-shaped frame, and the clamping unit is a structure for clamping the steel wire 4. Under the driving action of the driving member, the clamping unit can synchronously perform linear reciprocating motion on the frame 1, and the two clamping units simultaneously perform linear motion in the same direction so that the steel wires of the clamping parts of the two move back and forth to achieve cutting of the block blank. This is a prior art and will not be repeated. In this embodiment, two square plates 5 are symmetrically arranged on both sides of the bottom end of the frame 1, and a winding roller 3 is rotatably installed between the two square plates 5 on one side of the frame 1, and a unwinding roller 2 is rotatably installed between the two square plates 5 on the other side of the frame 1. The connection between the frame 1 and the square plate 5 is preferably detachable, so that the winding roller 3 and the unwinding roller 2 can be disassembled on the square plate 5, which is convenient for rewinding the steel wire 4 The whole is replaced. The winding roller 3 is a roller capable of winding the steel wire 4. The steel wire 4 is wound on the unwinding roller 2. The end of the steel wire 4 on the unwinding roller 2 is connected to the winding roller 3. The steel wire 4 passes through two clamping units, that is, the steel wire 4 is wound on the unwinding roller 2 in the initial state. Then, during arrangement, the end of the steel wire 4 is pulled to pass through the two clamping units and is wound by the unwinding roller 2. Subsequently, the winding roller 3 is rotated regularly so that the steel wire is gradually transferred from the unwinding roller 2 to the winding roller 3. The steel wire 4 is clamped by the clamping unit so that the part of the steel wire 4 between the two clamping units is in a straight state. The steel wire 4 is a material for cutting the blank. The steel wire 4 is driven by the clamping unit to perform a linear reciprocating motion (the unwinding roller 2 and the winding roller are controlled during cutting). 3 releases a portion of the steel wire to facilitate the linear reciprocating motion of the clamping unit), so that the steel wire 4 can cut the blank (the blank is a block blank that is subjected to constant temperature curing for 2 to 3 hours with a mixed slurry). While the steel wire 4 is performing a linear reciprocating motion, the frame 1 drives the two clamping units to move synchronously toward the bottom end of the blank, so that the steel wire 4 can move toward the bottom end of the blank while performing the reciprocating motion, so that the steel wire 4 can cut the blank. A plurality of groups of two mutually symmetrical clamping units and a replacement unit are arranged on the frame 1 to simultaneously cut the blank. When the steel wire 4 has cut the blank a certain number of times (e.g., 50 times), it is necessary to perform a cutting operation on the portion of the steel wire 4 that cuts the blank (for ease of description, this portion of the steel wire 4 is referred to as the cutting steel wire 4 in the following). The wire 4 is wound around the workpiece and the wire 5 is reeled in. The wire 4 is wound around the workpiece and the workpiece is reeled in. The wire 4 is wound around the workpiece and the workpiece is reeled in. The workpiece is reeled in and out of the workpiece, the workpiece is reeled in. The workpiece is reeled in and out of the workpiece, the workpiece is reeled in and out of the workpiece.

[0040] The disadvantage of the prior art is that the two ends of the steel wire 4 are clamped by the clamping unit. When the steel wire 4 cuts the blank, the two clamping units drive the steel wire 4 to perform a linear reciprocating motion. Since the steel wire 4 performs a linear reciprocating motion on the blank, the steel wire 4 is subject to certain wear and tear, and it is necessary to regularly replace the steel wire 4. When replacing the steel wire 4, the clamping unit is required to loosen the steel wire 4, and then the staff takes the steel wire 4 out of the clamping unit, and then clamps the two ends of the new steel wire 4 through the two clamping units. It is troublesome to replace the steel wire 4, and the number of steel wires 4 is large, and the time required for replacing the steel wire 4 is long, which affects the production efficiency of the blocks. In addition, since the connecting part of the end of the steel wire 4 does not contact the blank when the steel wire 4 performs a reciprocating linear motion to cut the blank, the wear and tear of the end of the steel wire 4 is small. Such replacement causes waste of steel wire 4 material, thereby increasing the production cost of the blocks.

[0041] The beneficial effects of the present invention are as follows: the steel wire 4 is clamped by two clamping units, and the steel wire 4 is synchronously driven by the two clamping units to perform linear reciprocating motion, so that the steel wire 4 can cut the blank; when the steel wire 4 needs to be replaced, the two clamping units synchronously release the clamping of the steel wire 4, drive the winding roller 3 to rotate, so that the winding roller 3 winds up the steel wire 4, and synchronously, the unwinding roller 2 unwinds the steel wire 4; after the winding roller 3 completes the winding of the steel wire 4, the two clamping units synchronously clamp the steel wire 4, and the replacement operation of the cutting steel wire 4 can be completed; this method of replacing the steel wire 4 is relatively convenient, saves the time for replacing the steel wire 4, and the steel wire 4 on the unwinding roller 2 can be fully utilized, reducing the waste of steel wire 4 material.

[0042] In this embodiment, when the clamping unit is clamping, the winding roller 3 and the unwinding roller 2 can release a portion of the steel wire to provide a pulling amplitude for the clamping unit during the reciprocating motion.

[0043] Preferably, the clamping unit includes a first rectangular frame 6, two through grooves 7 are symmetrically provided on both side walls of the first rectangular frame 6, a first clamping plate 8 is slidably installed on the top of the two through grooves 7, and a second clamping plate 9 is slidably installed on the bottom of the two through grooves 7, the first clamping plate 8 and the second clamping plate 9 are symmetrically arranged with each other, two positioning plates 10 are symmetrically installed on one side wall of the first rectangular frame 6, a bidirectional threaded rod 11 is rotatably installed between the two positioning plates 10, the two threaded parts of the bidirectional threaded rod 11 are respectively threadedly connected with the first clamping plate 8 and the second clamping plate 9, a first driving member 12 is provided on the positioning plate 10 at the top end of the first rectangular frame 6, and the output end of the first driving member 12 is connected to the bidirectional threaded rod 11.

[0044] Specifically, the staff uses a tool to pull the end of the steel wire 4 on the unwinding roller 2 through the portion between the first clamping plate 8 and the second clamping plate 9, and connects the end of the steel wire 4 to the winding roller 3. When the clamping unit needs to clamp the steel wire 4, each first driving member 12 is synchronously started (the first driving member 12 is a device with forward and reverse rotation at the output end, preferably a motor) to drive the bidirectional threaded rod 11 to rotate clockwise. Since the two threaded parts of the bidirectional threaded rod 11 are respectively connected to the first clamping plate 8 and the second clamping plate 9, The bidirectional threaded rod 11 is connected so that the bidirectional threaded rod 11 synchronously drives the first clamping plate 8 and the second clamping plate 9 to move toward the end close to the steel wire 4, so that the first clamping plate 8 and the second clamping plate 9 clamp the steel wire 4; when the clamping unit needs to release the steel wire 4, each first driving member 12 is synchronously started to drive the bidirectional threaded rod 11 to rotate counterclockwise, so that the bidirectional threaded rod 11 synchronously drives the first clamping plate 8 and the second clamping plate 9 to move toward the end away from the steel wire 4, so that the first clamping plate 8 and the second clamping plate 9 release their clamping of the steel wire 4.

[0045] Preferably, a connecting plate 13 is commonly connected to the side walls of the two positioning plates 10 on the same side of the first rectangular frame 6, and two second driving members 14 are symmetrically arranged on the top of the frame body 1, and the output ends of the two second driving members 14 are respectively connected to a U-shaped frame 15, and each U-shaped frame 15 corresponds to a first rectangular frame 6. A plurality of third driving members 16 are evenly arranged on the two U-shaped frames 15, and the output ends of each of the third driving members 16 are connected to the outer wall of the corresponding connecting plate 13. Specifically, due to the connecting plate 13 and the first rectangular frame 6 The force is borne by the third driving member 16, which may cause damage to the third driving member 16. In this embodiment, two symmetrical slide rails 49 are set on the outer wall of each U-shaped frame 15, and the positioning plate 10 is slidably installed in the slide rails 49 by sliding cooperation. The slide rails 49 bear the force of the connecting plate 13 and the first rectangular frame 6 to ensure the sliding stability of the connecting plate 13 and the first rectangular frame 6. When it is necessary to drive the clamping unit to perform linear reciprocating motion, each third driving member 16 (the third driving member 16 is an output end capable of linear reciprocating motion) is synchronously started. The moving original component, preferably a hydraulic cylinder, drives the connecting plate 13 to perform linear reciprocating motion, the connecting plate 13 drives the first rectangular frame 6 to perform linear reciprocating motion through the positioning plate 10, the first rectangular frame 6 drives the positioning plate 10 to perform linear reciprocating motion in the slide rail 49, and the first rectangular frame 6 drives the steel wire 4 to perform linear reciprocating motion through the first clamping plate 8 and the second clamping plate 9, so that the steel wire 4 can cut the blank. It should be noted that the amplitude of the linear reciprocating motion of the steel wire 4 is small, so that the steel wire 4 will not damage the blank when cutting the blank. The side wall is damaged. When the steel wire 4 needs to move from the top of the blank to its bottom, the second driving member 14 is started (the second driving member 14 is a component capable of linear reciprocating motion at the output end, preferably a hydraulic cylinder) to drive the U-shaped frame 15 to move toward the bottom of the blank. The U-shaped frame 15 drives the positioning plate 10 and the first rectangular frame 6 to move toward the bottom of the blank through the third driving member 16 and the connecting plate 13. The first rectangular frame 6 drives the steel wire 4 to move toward the bottom of the blank through the first clamping plate 8 and the second clamping plate 9, so that the steel wire 4 can perform a stable cutting operation on the blank.

[0046] In another embodiment provided by the present invention, a locking unit is provided on each of the first clamping plate 8 and the second clamping plate 9, and the locking unit includes an L-shaped plate 17. Two L-shaped plates 17 are symmetrically provided on the outer walls of the first clamping plate 8 and the second clamping plate 9. A first clamping roller 18 is rotatably installed between the two L-shaped plates 17 on the first clamping plate 8 via a driven shaft, and a second clamping roller 19 is rotatably installed between the two L-shaped plates 17 on the second clamping plate 9 via a driven shaft. The distance between the second clamping roller 19 and the first rectangular frame 6 is smaller than the distance between the first clamping roller 18 and the first rectangular frame 6. The first clamping roller 18 and the second clamping roller 19 both perform a clamping and limiting operation on the steel wire 4, so that the steel wire 4 forms an "S"-shaped structure under the clamping action of the first clamping roller 18 and the second clamping roller 19.

[0047] Specifically, the first holding roller 18 corresponds to the bottom end of the first rectangular frame 6, the second holding roller 19 corresponds to the top end of the first rectangular frame 6, and the distance between the second holding roller 19 and the first rectangular frame 6 is smaller than the distance between the first holding roller 18 and the first rectangular frame 6. When the staff pulls the steel wire 4 from the unwinding roller 2 to one end of the winding roller 3, the steel wire 4 passes through the bottom end of the first holding roller 18, so that the steel wire 4 is pressed against the bottom end of the first holding roller 18, and then the steel wire 4 goes around to the top end of the second holding roller 19, and then enters between the first clamping plate 8 and the second clamping plate 9, so that the steel wire 4 is pressed against the top end of the second holding roller 19, so that the steel wire 4 passes through the first holding roller 18. The part with the second clamping roller 19 is of "S" type structure; when the clamping unit needs to loosen the steel wire 4, the bidirectional threaded rod 11 synchronously drives the first clamping plate 8 and the second clamping plate 9 to move toward the end away from the steel wire 4, and the first clamping plate 8 drives the L-shaped plate 17 and the first clamping roller 18 to move toward the top end of the frame 1, and at the same time, the second clamping plate 9 drives the L-shaped plate 17 and the second clamping roller 19 to move toward the bottom end of the frame 1, until the first clamping roller 18 and the second clamping roller 19 move to the same height (that is, the bottom end of the first clamping roller 18 and the top end of the second clamping roller 19 are at the same height), at this time, the steel wire 4 is at the same height between the first clamping roller 18 and the second clamping roller The part on 19 is in a horizontal state. When the winding roller 3 winds up the steel wire 4, the pressure on the steel wire 4 will not act on the first clamping roller 18 and the second clamping roller 19, so that the first clamping roller 18 and the second clamping roller 19 are no longer subjected to the squeezing force of the steel wire 4, and when the steel wire 4 is in a horizontal state, it will not affect the winding operation of the winding roller 3 on the steel wire 4; when the clamping unit needs to clamp the steel wire 4, the bidirectional threaded rod 11 synchronously drives the first clamping plate 8 and the second clamping plate 9 to move toward one end close to the steel wire 4. During this process, the first clamping plate 8 drives the L-shaped plate 17 and the first clamping roller 18 to move toward one side of the bottom end of the frame body 1. At the same time, the second clamping plate 9 drives the L-shaped plate 17 and the second clamping roller 19 move toward the top side of the frame body 1 until the first clamping plate 8 and the second clamping plate 9 perform a stably clamping operation on the steel wire 4. At this time, the steel wire 4 forms an "S"-shaped structure under the clamping action of the first clamping roller 18 and the second clamping roller 19, so that the first clamping roller 18 and the second clamping roller 19 perform a certain winding and locking operation on the steel wire 4. At this time, the winding roller 3 no longer performs a winding operation on the steel wire 4. The steel wire 4 is tightened by pulling the first clamping roller 18 and the second clamping roller 19 through the misalignment, so that the steel wire 4 has a certain winding and locking operation, so that the steel wire 4 will not slide under the clamping action of the clamping unit, thereby improving the stability of the clamping unit clamping the steel wire 4.

[0048] In another embodiment provided by the present invention, two second rectangular frames 20 are symmetrically installed on the side wall of one side near the pressing roller at the top of the first rectangular frame 6, the driven shaft on the first pressing roller 18 passes through the L-shaped plate 17 and is installed with a driven gear 21, and the side wall of the bottom end of the second rectangular frame 20 away from the first rectangular frame 6 is provided with driving teeth 22, and the driving teeth 22 are meshed with the driven gear 21; two third rectangular frames 23 are symmetrically installed on the side wall of one side near the pressing roller at the bottom end of the first rectangular frame 6, the driven shafts on the second pressing roller 19 all pass through the L-shaped plate 17 and are also installed with driven gears 21, and the side wall of the top end of the third rectangular frame 23 away from the first rectangular frame 6 is also provided with driving teeth 22, and the driving teeth 22 are meshed with the driven gear 21 on the second pressing roller 19.

[0049] Specifically, when the clamping unit needs to loosen the steel wire 4, the bidirectional threaded rod 11 synchronously drives the first clamping plate 8 and the second clamping plate 9 to move toward the end away from the steel wire 4. During the process, the first clamping plate 8 drives the L-shaped plate 17 and the first clamping roller 18 to move toward the top side of the frame body 1.

[0050] When the clamping unit needs to clamp the steel wire 4, the bidirectional threaded rod 11 synchronously drives the first clamping plate 8 and the second clamping plate 9 to move toward one end close to the steel wire 4. During the process, the first clamping plate 8 drives the L-shaped plate 17 and the first clamping roller 18 to move toward the bottom end of the frame body 1. Since the first clamping roller 18 is connected with a driven gear 21, and a plurality of active teeth 22 are arranged at the bottom end of the second rectangular frame 20, when the driven gear 21 and the active teeth 22 are meshed with each other, since the active teeth 22 are fixedly arranged, the driven gear 21 rotates under the meshing action of the active teeth 22, and the driven gear 21 drives the first clamping roller 18 to rotate, so that the first clamping roller 18 drives the steel wire 4 to move away from the end of the first rectangular frame 6. At the same time, the second clamping plate 9 drives the L-shaped plate 17 and the second clamping roller 19 to move toward the top end of the frame body 1. A driven gear 21 is connected to the tightening roller 19, and a driving tooth 22 is provided on the third rectangular frame 23. When the driven gear 21 and the driving tooth 22 are meshed with each other, since the driving tooth 22 is fixed, the driven gear 21 rotates under the meshing action of the driving tooth 22, and the driven gear 21 drives the second tightening roller 19 to rotate, so that the second tightening roller 19 drives the steel wire 4 to move away from the end of the first rectangular frame 6, so that the first tightening roller 18 and the second tightening roller 19 perform a certain pulling operation on the steel wire 4, so that the part of the steel wire 4 between the clamping units is in a straightened state, and the steel wire 4 forms an "S" shape structure under the tightening action of the first tightening roller 18 and the second tightening roller 19, so that the steel wire 4 has a certain winding lock, so that the steel wire 4 will not slide under the clamping action of the clamping unit, thereby improving the stability of the clamping unit clamping the steel wire 4.

[0051] In another embodiment provided by the present invention, each of the L-shaped plates 17 has an arc groove 24 at the top, and each of the arc grooves 24 has an arc plate 25 slidably installed therein, and both ends of each of the arc plates 25 close to the steel wire 4 are arranged as inclined surfaces, and each of the arc plates 25 is provided with a return plate 26, and each of the return plates 26 and the inner wall of the arc groove 24 are connected by a first elastic member 27, and each of the two ends of each of the arc plates 25 close to the driven gear 21 is provided with a driven block 28, an active groove 29 is provided on the side wall of the second rectangular frame 20 away from the active tooth 22 and close to the L-shaped plate 17, and an active groove 29 is provided on the side wall of the third rectangular frame 23 away from the active tooth 22 and close to the L-shaped plate 17, and each of the driven blocks 28 is tightly arranged with its corresponding active groove 29; the top and bottom ends of the active groove 29 are both straight grooves 291, and the two straight grooves 291 are connected by an inclined groove 292, and the straight groove 291 at the top of the second rectangular frame 20 is connected to the L-shaped plate 1 The distance between the first and second abutting rollers 18 and 19 is greater than the distance between the linear groove 291 at the bottom and the L-shaped plate 17, and the distance between the linear groove 291 at the top of the third rectangular frame 23 and the L-shaped plate 17 is less than the distance between the linear groove 291 at the bottom and the L-shaped plate 17; both ends of the first abutting roller 18 and the second abutting roller 19 are uniformly provided with a plurality of through holes 30 along the axial direction thereof, and a clamping rod 31 is slidably installed in each of the through holes 30, and a reset rod 32 is provided on each of the clamping rods 31, and each of the reset rods 32 and the corresponding reset rods 32 are provided with a plurality of through holes 30, and each of the two ends of the first abutting roller 18 and the second abutting roller 19 is uniformly provided with a plurality of through holes 30 along the axial direction thereof, and each of the two ends of the first abutting roller 18 and the second abutting roller 19 is uniformly provided with a plurality of through holes 30 ... The inner walls of the corresponding perforations 30 are connected by a second elastic member 33, and the end of each clamping rod 31 close to the arc plate is inclined, and the inclined ends of each clamping rod 31 are wedge-matched with the inclined surfaces of the corresponding arc plates. The arc groove 24 and the arc plate 25 are arranged at the position where the steel wire 4 is pressed against the first pressing roller 18 and the second pressing roller 19, that is, in the circumferential direction of the first pressing roller 18 or the second pressing roller 19, the arc groove 24 and the arc plate 25 are in a position where the steel wire 4 overlaps with each other.

[0052] Specifically, when the clamping unit needs to loosen the steel wire 4, the bidirectional threaded rod 11 synchronously drives the first clamping plate 8 and the second clamping plate 9 to move toward the end away from the steel wire 4. During this process, the first clamping plate 8 drives the L-shaped plate 17 and the first clamping roller 18 to move toward the top side of the frame body 1. At the same time, the second clamping plate 9 drives the L-shaped plate 17 and the second clamping roller 19 to move toward the bottom side of the frame body 1. The L-shaped plate 17 drives the arc plate 25 and the driven block 28 to slide along the trajectory of the active groove 29. The driven block 28 slides from the straight groove 291 closer to the L-shaped plate 17 to the end of the inclined groove 292, and then slides from the inclined groove 292 to the end of the straight groove 291 farther from the L-shaped plate 17. When the driven plate slides to a distance When the driven block 28 is on the linear groove 291 farther from the L-shaped plate 17, under the rebound action of the first elastic member 27 (the first elastic member 27 is a component capable of telescopic reset, preferably a spring), the driven block 28 slides toward the end away from the steel wire 4 (because when the driven block 28 is pressed against the linear groove 291 closer to the L-shaped plate 17, the first elastic member 27 is squeezed by the return plate 26, and the first elastic member 27 is in a compressed state), and under the rebound action of the second elastic member 33 (the second elastic member 33 is a component capable of telescopic reset, preferably a spring), the clamping rod 31 slides toward the end away from the steel wire 4, so that the clamping rod 31 releases the clamping operation on the steel wire 4, so that the winding roller 3 can stably wind the steel wire 4.

[0053] When the clamping unit needs to clamp the steel wire 4, the bidirectional threaded rod 11 synchronously drives the first clamping plate 8 and the second clamping plate 9 to move toward one end close to the steel wire 4. During this process, the first clamping plate 8 drives the L-shaped plate 17 and the first clamping roller 18 to move toward the bottom end of the frame 1. At the same time, the second clamping plate 9 drives the L-shaped plate 17 and the second clamping roller 19 to move toward the top end of the frame 1. The L-shaped plate 17 drives the arc plate 25 and the driven block 28 to slide along the trajectory of the active groove 29. The driven block 28 slides from the straight groove 291 farther from the L-shaped plate 17 to the end of the inclined groove 292, and then slides from the inclined groove 292 to the end of the straight groove 291 closer to the L-shaped plate 17. When the driven plate slides to a distance When the driven plate is on the straight groove 291 closer to the L-shaped plate 17, the driven plate drives the arc plate 25 to slide in the arc groove 24 toward one end of the L-shaped plate 17, and the arc plate 25 squeezes the first elastic member 27 through the return plate 26, so that the first elastic member 27 is in a compressed state. When the driven plate slides to the inclined groove 292 position, the driven gear 21 and the active gear 22 are meshed with each other, and the driven gear 21 rotates under the meshing action of the active gear 22. The driven gear 21 drives the first clamping roller 18 and the second clamping roller 19 to rotate, so that the first clamping roller 18 and the second clamping roller 19 drive the clamping rod 31 to rotate. Since the arc plate 25 gradually slides toward one end of the L-shaped plate 17, and the clamping rod 31 rotates along with the first clamping roller 292, the arc plate 25 gradually slides toward one end of the L-shaped plate 17, and the clamping rod 31 rotates along with the first clamping roller 292. The tightening roller 18 and the second tightening roller 19 rotate. Since the end of the clamping rod 31 close to the arc plate is inclined, and the inclined ends of each clamping rod 31 are wedge-shapedly matched with the inclined surfaces of the corresponding arc plates, when the clamping rod 31 slides to the arc plate position, it will slide toward the end close to the steel wire 4, so that the clamping rod 31 clamps the steel wire 4, and since the arc groove 24 and the arc plate 25 are arranged at the position where the steel wire 4 is pressed against the first tightening roller 18 and the second tightening roller 19, the clamping rod 31 clamps the steel wire 4 and as the first tightening roller 18 and the second tightening roller 19 rotate, the steel wire 4 moves toward the end away from the first rectangular frame 6 under the clamping action of the clamping rod 31, so that the first and second tightening rollers 18 and 19 rotate. A clamping roller 18 and a second clamping roller 19 perform a certain pulling operation on the steel wire 4, so that the portion of the steel wire 4 between the clamping units is in a straightened state, and the steel wire 4 forms an "S"-shaped structure under the clamping action of the first clamping roller 18 and the second clamping roller 19, so that the steel wire 4 has a certain winding lock, so that the steel wire 4 will not slide under the clamping action of the clamping unit, thereby improving the stability of the clamping unit clamping the steel wire 4, that is, the steel wire 4 can not only rotate on the first clamping roller 18 and the second clamping roller 19 with the first clamping roller 18 and the second clamping roller 19, but the first clamping roller 18 and the second clamping roller 19 can also tighten the steel wire 4 into an "S"-shaped structure, thereby improving the tightening effect of clamping the steel wire 4.

[0054] In another embodiment provided by the present invention, a groove 34 is respectively provided on the first clamping plate 8 and the second clamping plate 9, and a limit plate 35 is slidably installed in each of the grooves 34, and a plurality of semicircular arc blocks 36 are evenly arranged on each of the limit plates 35, and a trapezoidal groove 37 is respectively provided on the end of each of the limit plates 35 away from the steel wire 4, and a plug hole 38 is respectively provided on the side walls of each of the trapezoidal grooves 37, and a trapezoidal plate 39 that is adapted to the shape of the trapezoidal groove 37 is respectively provided on the inner wall of each of the grooves 34, and the trapezoidal plate 39 and the corresponding limit plate 35 are connected by two symmetrically arranged fourth elastic members 40, and a straight groove 41 is respectively provided on each of the trapezoidal plates 39, and an inverted trapezoidal block 42 is slidably installed in each of the straight grooves 41, and each of the A follower rod 43 is installed on each trapezoidal block 42, and each of the follower rods 43 passes through the inner wall of the straight groove 41. An oblique groove 44 is provided on the inclined surfaces on both sides of each trapezoidal block 42. Each of the trapezoidal plates 39 and the inner wall of the corresponding straight groove 41 are connected by a third elastic member 45. Two through holes 46 are symmetrically provided on the side walls on both sides of each trapezoidal plate 39. A plug rod 47 is slidably installed in each of the through holes 46, and the abutting ends of the plug rod 47 and the trapezoidal groove 37 are inclined surfaces with the same inclination angle as the inclined surface of the trapezoidal groove 37. Each of the plug rods 47 is plugged into and matched with the corresponding plug hole 38. A sliding round rod 48 is provided at the end of each of the plug rods 47, and each of the sliding round rods 48 is slidably installed in the corresponding oblique groove 44.

[0055] Specifically, when the clamping unit needs to loosen the steel wire 4, the bidirectional threaded rod 11 synchronously drives the first clamping plate 8 and the second clamping plate 9 to move toward one end away from the steel wire 4, and the first clamping plate 8 and the second clamping plate 9 drive the limiting plate 35 to slide toward one end away from the steel wire 4 so that the limiting plate 35 releases the clamping operation of the steel wire 4, and the limiting plate 35 drives the driven rod 43 to move toward one end away from the steel wire 4 until the driven rod 43 is pressed against the inner wall of the first rectangular frame 6, and the driven rod 43 continues to move toward one end away from the steel wire 4, so that under the pressing action of the first rectangular frame 6, the driven rod 43 moves toward one end inside the straight groove 41, and the driven rod 43 drives the trapezoidal block 42 to slide toward one end inside the straight groove 41, and the trapezoidal block 42 presses the third elastic member 45 (the third elastic member 45 is an original member that can be telescopically reset, preferably The third elastic member 45 is in a compressed state. Since an oblique groove 44 is provided on each of the inclined surfaces on both sides of the trapezoidal block 42, and the oblique groove 44 and the sliding round rod 48 are slidably arranged, when the trapezoidal block 42 slides toward one end inside the straight groove 41, the oblique groove 44 of the trapezoidal block 42 drives the sliding round rod 48 to slide toward one end inside the straight groove 41, and the sliding round rod 48 drives the insertion rod 47 to slide out of the insertion hole 38, so that the insertion rod 47 releases the positioning operation of the trapezoidal block 42. Under the rebound action of the fourth elastic member 40 (the fourth elastic member 40 is an original member capable of telescopic reset, preferably a spring), the limit plate 35 slides toward one end of the steel wire 4, so that the trapezoidal plate 39 no longer supports the limit plate 35, so that there is a certain gap between the trapezoidal plate 39 and the limit plate 35.

[0056] When the clamping unit needs to clamp the steel wire 4, the bidirectional threaded rod 11 synchronously drives the first clamping plate 8 and the second clamping plate 9 to move toward one end close to the steel wire 4, and the first clamping plate 8 and the second clamping plate 9 drive the limiting plate 35 to slide toward one end close to the steel wire 4 so that the limiting plate 35 clamps the steel wire 4, and the limiting plate 35 drives the driven rod 43 to move toward one end close to the steel wire 4 until the limiting plate 35 and the steel wire 4 are pressed against each other, so that the semicircular arc block 36 on the limiting plate 35 is pressed against the steel wire 4, and the driven rod 43 is separated from the inner wall of the first rectangular frame 6, and under the rebound action of the third elastic member 45, the third elastic member 45 drives the trapezoidal block 42 to move away from one end of the steel wire 4 Sliding, since there is an oblique groove 44 on each of the inclined surfaces on both sides of the trapezoidal block 42, and the oblique groove 44 and the sliding round rod 48 are slidably arranged, when the trapezoidal block 42 slides toward the end away from the steel wire 4, the oblique groove 44 of the trapezoidal block 42 drives the sliding round rod 48 to slide toward the outer end of the straight groove 41, and the sliding round rod 48 drives the insertion rod 47 to slide out of the through hole 46, and the insertion rod 47 extends out of the trapezoidal plate 39, so that the insertion rod 47 releases the positioning operation of the trapezoidal block 42. Since the limiting plate 35 and the driven block 28 slide synchronously, when the limiting plate 35 slides to be tightly pressed against the steel wire 4, the driven block 28 slides from the straight groove 291 farther from the L-shaped plate 17 to the L-shaped plate 1 7, the limiting plate 35 continues to slide toward one end of the steel wire 4, and the limiting plate 35 squeezes the fourth elastic member 40, so that the fourth elastic member 40 is in a compressed state. The limiting plate 35 slides in the straight groove 41, and the first clamping plate 8 and the second clamping plate 9 drive the trapezoidal plate 39 to slide toward one end of the trapezoidal groove 37. Since the fourth elastic member 40 has a certain degree of expansion and contraction, the trapezoidal plate 39 gradually provides an extrusion force for the limiting plate 35 during the sliding process of the trapezoidal plate 39 into the trapezoidal groove 37, until the trapezoidal plate 39 and the trapezoidal groove 37 on the limiting plate 35 are pressed against each other. At this time, the trapezoidal plate 39 provides a large driving force for the limiting plate 35, so that the limiting plate 3 5 performs a stable clamping operation on the steel wire 4, and the semicircular arc blocks 36 are evenly arranged on the limit plate 35, so that the semicircular arc blocks 36 clamp the steel wire 4 at multiple points, thereby improving the stability of the limit plate 35 clamping the steel wire 4. In the process of the trapezoidal plate 39 sliding into the trapezoidal groove 37, the driven gear 21 and the active gear 22 are synchronously engaged with each other, so that the first clamping roller 18 and the second clamping roller 19 perform a certain pulling operation on the steel wire 4 when rotating, so that the part of the steel wire 4 between the clamping units is in a straight state, and the steel wire 4 forms an "S" shape structure under the clamping action of the first clamping roller 18 and the second clamping roller 19, so that the steel wire 4 has a certain winding lock.

[0057] The clamping operation of the limit plate 35 on the steel wire 4 is divided into two movement processes: (1) When the limit plate 35 moves to the contact position with the steel wire 4, due to the synchronous sliding of the limit plate 35 and the driven block 28, the driven block 28 slides from the linear groove 291 farther from the L-shaped plate 17 to the linear groove 291 closer to the L-shaped plate 17, that is, at this time, the driven block 28 drives the arc plate 25 to slide in the arc groove 24 toward the end of the L-shaped plate 17, and the driven gear 21 slides to the position where it meshes with the active gear 22; (2) The trapezoidal plate 39 gradually moves to the limit plate 35. During the sliding process in the trapezoidal groove 37, the driven gear 21 rotates under the meshing action of the active tooth 22, and the driven gear 21 drives the first clamping roller 18 and the second clamping roller 19 to rotate. In the process of the first clamping roller 18 and the second clamping roller 19 rotating to tighten the steel wire 4, the limit plate 35 synchronously and gradually clamps the steel wire 4, thereby improving the tension of the steel wire 4 between the first clamping roller 18 and the second clamping roller 19, and the first clamping roller 18 and the second clamping roller 19 can tighten the steel wire 4 into an "S" shape structure, thereby improving the tightening effect of clamping the steel wire 4.

[0058] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
