Fiber reinforcement mechanism is one of the types of reinforcement materials. Fiber-reinforced composite materials are composed of high-strength, high-modulus, continuous fibers or discontinuous fibers and a matrix.

DETAILED DESCRIPTION

[0025] The present invention is further described below in conjunction with the accompanying drawings.

[0026] like Figure 1-3 As shown, the equidistant steel wire fiber cutting device of the present invention comprises a wire withdrawing assembly 1, a wire feeding assembly 2, a clamping assembly 3 and a cutting assembly 4;

[0027] The wire withdrawal assembly 1 comprises a base 11 and a steel wire fiber drum 12 rotatably mounted on the base 11;

[0028] The wire feeding assembly 2 includes a belt conveyor 21 and a guide drum 22. A plurality of guide grooves 24 are arranged in parallel on the bearing surface of the belt 23 of the belt conveyor 21 along its moving direction. The guide drum 22 includes a plurality of guide grooves 24, one end of which corresponds to the guide grooves 24 on the belt 23 one by one, and the other end of which corresponds to the plurality of wire withdrawing assemblies 1 one by one through an arc-shaped transition of the drum body.

[0029] The clamping assembly 3 is located at one end of the belt conveyor 21 away from the guide cylinder 22, and includes a bracket 31 and a clamping plate 32. The bracket 31 can move forward and backward along the conveying direction of the belt conveyor 21 under the action of the driving mechanism. The clamping plate 32 is rotatably installed on the top of the bracket 31, including an upper clamping plate and a lower clamping plate that can be opened and closed. The upper clamping plate and the lower clamping plate are provided with mutually matching clamping grooves 33 on the opposite sides. The clamping grooves 33 correspond to the guide grooves 24 on the belt 23. The clamping assembly 3 includes two sets, and the two sets of clamping assemblies 3 are respectively located at the front and rear ends of its movement path and operate alternately.

[0030] The cutting assembly 4 is located at a side of the clamping assembly 3 away from the belt conveyor 21 , and includes a knife seat 41 , a cutting motor 42 located on the top of the knife seat 41 , and a blade 43 installed on the output shaft of the cutting motor 42 .

[0031] The working process of the present invention is: before starting the equipment, first place the steel wire fiber drum 12 to be cut on the wire withdrawal assembly 1. To improve efficiency, multiple wire withdrawal assemblies 1 can be set up, and then the ends of the steel wire fibers on all the wire withdrawal assemblies 1 are passed through the guide cylinder 22 of the wire feeding assembly 2 and fed into the guide grooves 24 of the belt 23. Then, the steel wire fibers are pulled to the clamping assembly 3, and the steel wire fibers are clamped in the clamping grooves 33 of the clamping plate 32 by closing the upper clamping plate and the lower clamping plate. After completing the preparation work, the equipment can be started to realize the automatic and continuous operation of the equipment. Its operation process is as follows Figure 4 As shown, first, under the action of the clamping assembly 3, the belt conveyor 21 and the wire withdrawal mechanism 1, the steel wire fiber is in a taut state and slightly rests on the guide groove 24 of the belt 23. The friction force of the belt 23 on the steel wire fiber provides power to achieve continuous and stable transportation of the steel wire fiber. Then, the two sets of clamping assemblies 3 run back and forth alternately, one after the other. When one set of clamping assemblies 3 pulls the steel wire fiber to the farthest distance, the other set of clamping assemblies 3 just returns to the nearest position and clamps the steel wire fiber through the clamping plate 32. At this time, the distance between the two sets of clamping assemblies is the length of the steel wire fiber to be cut, and at this time, the two clamping plates 32 clamp the steel wire fiber. The cutting assembly 4 can be used to cut the steel wire fiber at any position between the two sets of clamping assemblies 3. Finally, the two sets of clamping assemblies 3 run back and forth to achieve continuous equidistant cutting of the steel wire fiber. Of course, the whole process inevitably requires some controllers and automation programs to ensure the coordinated operation of each component, but these are relatively conventional control methods that can be easily obtained. The focus of this application is on the mechanical structure.

[0032] For the wire withdrawal assembly 1, in order to assist the wire feeding assembly 2 in feeding the wire, a rotating shaft 13 and a wire withdrawal motor 14 for driving the rotating shaft 13 to rotate are provided on the base 11 of the wire withdrawal assembly 1. The middle part of the rotating shaft 13 is rotatably connected to the base 11, one end is connected to the wire withdrawal motor 14 through gear transmission, and the other end is detachably connected to the steel fiber drum 12. The steel fiber drum 12 may be large in size and heavy in weight. If the steel fiber drum 12 is rotated only by the steel fiber, it may cause the steel fiber to break. After the rotating shaft 13 and the wire withdrawal motor 14 are provided, the steel fiber drum 12 can be driven to rotate with the operation of the belt conveyor 21 to achieve complex wire feeding, thereby preventing the steel fiber from being pulled off.

[0033] For the wire feeding assembly 2, the belt conveyor 21 includes a frame 25, a front roller 26 and a rear roller 27 rotatably mounted on the frame 25, and a belt wound between the front roller 26 and the rear roller 27. The frame 25 is also provided with a wire feeding motor 28, which is connected to the front roller 26 through a chain drive or a belt drive. The length of the belt 23 is reasonably selected according to the actual situation. If it is too long, the middle part of the belt 23 is easy to collapse, resulting in separation from the steel wire fiber. If it is too short, it cannot provide enough stable friction for the steel wire fiber.

[0034] For the guide groove 24 on the belt 23, in order to prevent the steel wire fiber from hitting a sharp part and breaking or getting stuck in the seam, the guide groove 24 on the belt 23 is preferably an arc-shaped guide groove. When the steel wire fiber is transported at high speed on the belt 23, it is very likely that the wire will jump or go out of line. In order to avoid unnecessary accidents caused by such a situation, a detachable protective cover 29 is also provided on the frame 25, and the protective cover 29 covers the belt. The protective cover 29 can play a certain limiting role on the steel wire fiber when the wire goes out or jumps, avoiding injuries. At the same time, the steel wire fiber is easy to block the guide groove 24 during the feeding process. When the blockage occurs, the protective cover 29 can be removed to facilitate cleaning and handling, which can effectively extend the service life of the belt 23.

[0035] For the guide cylinder 22, its material is preferably wear-resistant plastic, such as nylon or POM. For easy installation, the end of the guide cylinder 22 close to the belt conveyor 21 is first fixed on a substrate, and the other end is a free end, and then the substrate is fixedly connected to the frame 25 of the belt conveyor 21. The guide cylinder 22 is fixed at one end and free at the other end, which can play a certain buffering role in the transportation of steel wire fibers and prevent the steel wire fibers from colliding and breaking with the end of the guide cylinder 22 during the withdrawal process. Further, the guide cylinder 22 is preferably a tapered cylinder, that is, the end close to the substrate has a smaller diameter and the end away from the substrate has a larger diameter. Since the diameter of the steel wire fiber is generally 0.2mm, the diameter of the small end of the guide cylinder can be designed to be 0.3mm, and the diameter of the large end can be designed to be 0.5mm, which is convenient for the steel wire fibers to gather at the entrance of the belt conveyor 21 and can fully avoid the collision of the steel wire fibers with the end of the guide cylinder 22.

[0036] For the clamping assembly 4, its key parts are the driving mechanism for controlling the forward and backward movement of the bracket 31 and the control mechanism for controlling the rotation and opening and closing of the splint 32. Among them, for the driving mechanism for controlling the forward and backward movement of the bracket 31, the present application provides two structural forms. The first is that the driving mechanism of the clamping assembly 4 is a telescopic mechanism such as a hydraulic rod, a pneumatic rod or a linear motor, one end of the driving mechanism is fixedly connected to the belt conveyor 21 or the ground, and the other end is connected to the bracket 31; the other is that the driving mechanism includes a guide rail and a driving trolley, the guide rail is installed on the ground, and its extension direction is consistent with the transportation direction of the belt conveyor 21. The driving trolley is located at the bottom of the bracket 31 and can move forward and backward along the guide rail. The above two methods can realize the forward and backward movement of the bracket 31 with a certain control circuit, and the operation is stable, meeting the traction requirements of the steel wire fiber. In order to avoid affecting the steel wire fiber during the forward and backward movement of the bracket 31, it is best to set the brackets 31 of the two sets of the clamping assembly 3 on both sides of the belt conveyor 21, and one end of the splint 32 is connected to the bracket 31. The rotation and opening and closing of the clamping plate 32 can be realized by using a motor, pneumatic or hydraulic mechanism, and there are many similar structures in the prior art. The specific working process of the clamping plate 32 is: when the clamping assembly 3 is located near the belt conveyor 21, the upper and lower clamping plates are closed to clamp the steel wire fibers, and then the clamping plate 32 moves forward with the bracket 31 under the action of the driving mechanism. When it reaches the farthest position, the cutting is completed, and then the clamping plate 32 rotates outward, opens the upper and lower clamping plates, and the steel wire fibers fall off and are collected. Then the bracket 31 returns to its original position, and when another set of clamping assemblies 3 reaches the farthest position, the clamping plate 32 is rotated to the steel wire fiber area, and the clamping plate 31 is closed to clamp the steel wire fibers, and this cycle is repeated.

[0037] Finally, for the cutting assembly 4, in addition to using the cutting knife in the form of the fan blade structure mentioned above, a gate knife or a more advanced laser cutting machine or wire cutting machine can also be used as a substitute.
