Description

Technical Field

[0001] The invention relates to the technical field of blended yarn processing equipment, in particular to a tensile performance detection device for blended yarn processing. Background Art

[0002] Blended yarn is a yarn made by mixing two or more different types of fibers. These fibers can be natural fibers and chemical fibers, or a combination of different types of natural or chemical fibers. The production process of blended yarn includes raw material screening, fiber opening, pre-combining, pre-combining and winding, drawing, roving and spun yarn, etc. After multiple processes such as combining, drawing and twisting, the blended yarn that meets the requirements is finally made.

[0003] The existing tensile performance testing device for blended yarn processing needs to perform a clamping operation first during testing to clamp the blended yarn on the first clamping ring and the second clamping ring. After the tensile performance test is completed, the clamping operation needs to be performed again during the next test to install the blended yarn. Such repeated installation operations are not only time-consuming and labor-intensive, but also affect the continuity of the testing work and reduce work efficiency. In view of the above problems, the following solutions are proposed. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a tensile property testing device for blended yarn processing, comprising a circulating wire pulling mechanism, the circulating wire pulling mechanism also comprising a machine case shell, a sliding block is slidably connected to the inner wall of the machine case shell, a fixing ring is fixedly connected to the outer wall of the sliding block, and a rotating block is rotatably connected to the inner wall of the fixing ring; A fixed anti-wear mechanism, the fixed anti-wear mechanism comprises a rack fixedly connected to the inner wall of the chassis shell, a sliding convex ring is slidably connected to the inner wall of the fixed ring, and a connecting groove 1 is opened on the inner wall of the fixed ring; The wire breaking and disengaging mechanism comprises a connecting hole arranged on the inner wall of the rotating block, a connecting groove 2 is arranged on the inner wall of the rotating block, and a telescopic rod is slidably connected to the inner wall of the rotating block.

[0005] Preferably, the circulating wire pulling mechanism also includes a clamping column slidably connected to the inner wall of the rotating block, a fixed bracket is fixedly connected to the inner wall of the chassis shell, a motor is fixedly connected to the top of the fixed bracket, a sprocket is fixedly connected to the outer wall of the motor, and a chain is meshingly connected to the outer wall of the sprocket. The fixed bracket can ensure that the motor can rotate normally during operation to avoid reversing and deviation during rotation. When the motor is powered on, it drives the sprocket to rotate, and then the rotation of the sprocket can drive the chain to rotate, thereby providing the main power source for the operation of the subsequent components.

[0006] Preferably, the circulating wire pulling mechanism also includes a fixed block 1 fixedly connected to the outer wall of the chain, a spring expansion block slidably connected to the inner wall of the fixed block 1, a protruding strip block slidably connected to the inner wall of the chassis shell, a spring plate fixedly connected to the outer wall of the protruding strip block, the outer wall of the spring plate is slidably connected to the inner wall of the chassis shell, and a hydraulic pipe 1 is fixedly connected to the inner wall of the chassis shell. Since the fixed block 1 is fixed on the chain, when the chain rotates, it will drive the fixed block 1 and the spring expansion block to rotate together. When the fixed ring moves downward, the sliding block will contact the protruding strip block and squeeze the protruding strip block inward, thereby causing the spring plate to push the hydraulic oil on the outside into the hydraulic pipe 1 to promote the operation of subsequent components.

[0007] Preferably, the circulating wire pulling mechanism also includes a U-shaped clamping rod slidably connected to the inner wall of the hydraulic tube one, the outer wall of the U-shaped clamping rod is slidably connected to the inner wall of the chassis shell, the outer wall of the chassis shell is fixedly connected with a fixed groove block, the inner wall of the fixed ring is slidably connected with a spring telescopic protrusion, the inner wall of the fixed ring is fixedly connected with a hydraulic tube two, the outer wall of the fixed ring is fixedly connected with a fixed block two, the inner wall of the fixed block two is fixedly connected to the outer wall of the hydraulic tube two, the hydraulic oil in the hydraulic tube one is pressurized and will push the U-shaped clamping rod to extend outward, limit the position of the fixed ring, and perform the tensile performance test of the blended yarn when the fixed ring stops moving, because the U-shaped clamping rod extends outward, the spring telescopic protrusion will contact it, and under pressure, the hydraulic oil on the top enters the fixed block two through the hydraulic tube two, thereby driving the subsequent components to operate.

[0008] Preferably, the circulating wire pulling mechanism also includes a sliding rod 1 slidably connected to the inner wall of the fixed block 2, a sliding groove block is slidably connected to the outer wall of the fixed ring, the outer wall of the sliding groove block is fixedly connected to the outer wall of the sliding rod 1, the inner wall of the sliding groove block is slidably connected with a spring telescopic bevel tooth, and the outer wall of the clamping column is fixedly connected with a telescopic spring 1. When the chain rotates, the sliding groove block can be driven by the fixed block 1 and the spring telescopic block, and the fixed ring can move therewith. The blended yarn is first wound around the surface of the clamping column, and then the motor is powered on to run. When the motor is powered on, the chain is driven to rotate by the chain teeth, and the chain rotation drives the fixed block 1 and the spring telescopic block to move. At this time, the spring telescopic block is stuck in the sliding groove block, and the spring telescopic block moves , which will drive the sliding groove block and the fixed ring to move. When the fixed ring moves downward, the blended yarn wrapped on the surface of the clamping column is pulled downward by the clamping column, so that the blended yarn is in a relatively tight and vertically downward state. When the fixed ring continues to move downward, the other fixed ring will also be driven by the chain to rotate downward from the top sprocket position. At this time, the clamping column is in an outwardly opened state due to the action of the telescopic spring. When the other fixed ring moves downward, the blended yarn in a relatively tight and vertically downward state will be in the middle of the two clamping columns of the other fixed ring. Then, when the other clamping column moves downward, the clamping column contacts the surface of the fixed groove block, moves downward close to the surface of the fixed groove block, and gradually contracts inward to hold the blended yarn between the two clamping columns. The spinning line is clamped to move downward, and when the fixed ring moves downward to the protruding strip, the sliding block will contact the protruding strip and squeeze the protruding strip to shrink inward. The protruding strip shrinks inward, and the hydraulic oil on its outside is squeezed through the spring plate, so that the hydraulic oil pushes the U-shaped clamping rod to move outward through hydraulic pipe 1 to limit the position of the other fixed ring. The other fixed ring is stuck by the U-shaped clamping rod during its downward movement, and the spring telescopic protrusion contacts the U-shaped clamping rod and shrinks upward under pressure, so that the hydraulic oil on the spring telescopic protrusion enters the fixed block 2 through hydraulic pipe 2, and then pushes the sliding rod 1 to move outward, and drives the sliding slot block to move outward together. At this time, the sliding slot block loses contact with the spring telescopic block, and the chain cannot drive the other fixed ring to move when it rotates. The other fixed ring will be restricted by the U-shaped clamping rod and cannot move, while the fixed ring will drive the blended yarn downward under the rotation of the chain to test the tensile performance of the blended yarn, and finally the blended yarn will be torn apart to complete the test. Then the fixed ring moves downward, causing the sliding block to lose contact with the protruding block, and the spring plate rebounds to drive the hydraulic oil in the hydraulic pipe to flow back, allowing the U-shaped clamping rod to retract. At this time, the other fixed ring will not be restricted by the clamping position, and the rebound of the spring telescopic protrusion drives the hydraulic oil in the hydraulic pipe to flow back, and the sliding groove block is reset to form a closed position. When the chain rotates, it drives the fixed block 1 and the spring telescopic block to move, so that the spring telescopic block contacts the spring telescopic bevel teeth, and the spring telescopic bevel teeth and the spring telescopic block are compressed and retracted, and the spring telescopic block is stuck in the sliding groove block.The chain can continue to drive the fixed ring to move for the next tensile performance test. Through the operation of the above components, the tensile performance test of the blended yarn only needs to be wound around the surface of the clamping column at the beginning of the test. After the equipment is started, the tensile performance test of the blended yarn can be repeated many times during operation, avoiding the need to clamp and fix the blended yarn again for each test, which is not only time-consuming and labor-intensive, but also inefficient.

[0009] Preferably, the fixed anti-wear mechanism also includes a groove opened on the outer wall of the rotating block, a protruding block is slidably connected to the inner wall of the fixed ring, and the outer wall of the protruding block is fixedly connected to a telescopic spring 2, a gear is fixedly connected to the outer wall of the rotating block, and a sliding plate is fixedly connected to the outer wall of the clamping column, and the outer wall of the sliding plate is slidably connected to the inner wall of the rotating block. Utilizing the characteristic that the above-mentioned fixed ring can cyclically move driven by the chain, a rack is provided, and when the fixed ring moves to start to move vertically downward, the gear and the rack will contact and form a meshing state during the downward movement of the fixed ring. When the fixed ring moves downward, the gear will rotate and drive the rotating block to rotate inside the fixed ring. When the rotating block rotates, the protruding block is squeezed to contract upward, so that the protruding block The hydraulic oil on the surface passes through the connecting groove 1, pushing the sliding convex ring to extend outward to the arc-shaped groove to limit the position of the sliding plate, and after the rotating block rotates one circle, the protruding block will continue to be stuck in the groove, and then the hydraulic oil will flow back to drive the sliding convex ring to reset. Through the operation of the above components, the blended yarn can be wound around the surface of the clamping column, so that the clamping of the blended yarn is tighter, avoiding looseness due to insufficient clamping during the tensile performance test, which affects the measurement result. The sliding plate is limited by the sliding convex ring to avoid the clamping column being ejected outward by the telescopic spring 1 when the rotating block rotates to the vertical state of the two clamping columns, so that the blended yarn is broken, and the tensile performance test of the blended yarn cannot be carried out this time.

[0010] Preferably, the fixed anti-wear mechanism also includes an arc-shaped groove opened on the outer wall of the sliding plate, a clamping plate is fixedly connected to the inner wall of the fixed groove block, a roller is rotatably connected to the inner wall of the fixed groove block, a rubber transmission belt is slidably connected to the outer wall of the roller, and a ball is rotatably connected to the inner wall of the clamping plate. By utilizing the above-mentioned characteristics, the clamping column will slide downward closely against the fixed groove block and gradually shrink inward to clamp the blended yarn. Two rubber transmission belts are set, and the rubber transmission belts are sleeved on the clamping plate inside the fixed groove block. When the clamping column moves to the position where it starts to move downward, the clamping column is opened outward by the action of the telescopic spring. In the process of the clamping column gradually moving downward, it contacts with the rubber transmission belt and gradually shrinks inward to clamp the blended yarn. The line is clamped, and then the rotating block is rotated through the rack to wind the blended yarn around the surface of the clamping column. The clamping column will continue to move downward and will shrink to the minimum value. At this time, the clamping column continues to move downward with the blended yarn. Since the clamping column is tightly attached to the rubber transmission belt, the rubber transmission belt is also driven through the action of the ball to slide around the clamping column and the plywood during the downward movement of the clamping column. When the clamping column moves downward, the rubber transmission belt will also move closely together to avoid the blended yarn from being entangled on the surface of the clamping column and moving downward, and generating friction with the surrounding area. In the friction that continues for a certain distance, the blended yarn is accidentally broken due to severe wear, which makes it impossible to continue to implement the tensile performance test.

[0011] Preferably, the wire breaking disengagement mechanism also includes a sliding rod second fixedly connected to the outer wall of the telescopic rod, the outer wall of the sliding rod second is slidably connected to the inner wall of the rotating block, the inner wall of the sliding rod second is slidably connected with a protruding scraper block, the outer wall of the protruding scraper block is slidably connected to the outer wall of the clamping column, and the outer wall of the protruding scraper block is fixedly connected with a telescopic spring third. By utilizing the characteristics that the clamping column can be extended and retracted inwardly during movement under the action of the fixed groove block and the rubber transmission belt, when the clamping column moves to the position where it starts to move downward, the clamping column is opened outwardly under the action of the telescopic spring first, and in the process of the clamping column gradually moving downward, it contacts with the rubber transmission belt and gradually contracts inwardly to clamp the blended yarn. When the clamping column contracts inwardly, the hydraulic oil inside the telescopic rod passes through the connecting groove second, passes through the connecting hole, and enters one side of the clamping column. The telescopic rod generates negative pressure due to the flow of the internal hydraulic oil, contracts inwardly, and drives the sliding rod second to move inwardly. The hydraulic oil on one side of the clamping column is squeezed and passed through the connecting hole, through the connecting groove 2, and enters the interior of the telescopic rod, so that the telescopic rod drives the sliding rod 2 to extend outward when the telescopic rod is extended. The protruding scraper block is always in close contact with the surface of the clamping column under the action of the telescopic spring 3, so that the sliding rod 2 drives the surface of the clamping column to be scraped together when it extends outward, and the broken blended yarn on the clamping column is pushed outward to prevent it from continuing to be wound around the clamping column and entering the interior of the chassis shell, so that the internal components of the equipment are entangled and stuck, affecting the normal working operation, or it is wound around the blended yarn being tested, so that the data of the tensile performance test is affected.

[0012] The present invention has the following beneficial effects: (1) The present invention utilizes the characteristic that when the chain rotates, the sliding groove block can be driven by the fixed block 1 and the spring expansion block, thereby causing the fixed ring to move therewith. The blended yarn is firstly wound on the surface of the clamping column, and then the motor is powered on. When the motor is powered on, the chain is driven to rotate by the chain teeth, and the chain rotation drives the fixed block 1 and the spring expansion block to move. At this time, the spring expansion block is stuck inside the sliding groove block. When the spring expansion block moves, it will drive the sliding groove block and the fixed ring to move. When the fixed ring moves downward, the blended yarn wound on the surface of the clamping column is pulled downward by the clamping column, so that the blended yarn is in a relatively tight and vertical downward state. When the fixed ring continues to move downward, the other fixed ring will also be driven by the chain from the top chain teeth. When the other fixing ring is moved downward, the clamping column is in an outwardly opened state under the action of the telescopic spring 1. When the other fixing ring is moved downward, the blended yarn, which is relatively tight and vertically downward, will be in the middle of the two clamping columns of the other fixing ring. Then, when the other clamping column moves downward, the clamping column contacts the surface of the fixed groove block, moves downward close to the surface of the fixed groove block, and gradually contracts inward to clamp the blended yarn between the two clamping columns and move it downward. When the fixing ring moves downward to the protruding strip block, the sliding block will contact the protruding strip block and squeeze the protruding strip block to shrink inward. The protruding strip block shrinks inward, and the hydraulic oil on the outside is squeezed through the spring plate, so that the hydraulic oil pushes the U-shaped clamping rod to move outward through the hydraulic pipe 1 to clamp the other fixing ring. The fixed ring is used to limit the position, and the other fixed ring is stuck by the U-shaped clamping rod when it moves downward. The spring expansion protrusion contacts the U-shaped clamping rod and shrinks upward under pressure, so that the hydraulic oil on the spring expansion protrusion enters the fixed block two through the hydraulic pipe two, and then pushes the sliding rod one to move outward, and drives the sliding slot block to move outward together. At this time, the sliding slot block loses contact with the spring expansion block, and the chain cannot drive the other fixed ring to move when rotating. At this time, the other fixed ring will be restricted by the U-shaped clamping rod and cannot move, and the fixed ring drives the blended yarn downward under the rotation of the chain to test the tensile performance of the blended yarn, and finally the blended yarn is torn off to end the test, and then the fixed ring moves downward, causing the sliding block to lose contact with the protruding strip, and the spring plate rebounds. The hydraulic oil in the hydraulic pipe 1 is driven to flow back, so that the U-shaped clamping rod retracts. At this time, the other fixed ring will not be restricted by the clamping position, and the spring telescopic protrusion rebounds to drive the hydraulic oil in the hydraulic pipe 1 to flow back, and the sliding groove block is reset to form a closed state. When the chain rotates, it drives the fixed block 1 and the spring telescopic block to move, so that the spring telescopic block contacts the spring telescopic bevel teeth. The spring telescopic bevel teeth and the spring telescopic block are compressed and retracted, and the spring telescopic block is stuck in the sliding groove block, so that the chain can continue to drive the fixed ring to move for the next tensile performance test. Through the operation of the above components, the tensile performance test of the blended yarn only needs to be wound around the surface of the clamping column at the beginning of the test. After the equipment is started, the tensile performance test of the blended yarn can be repeated many times during operation.Avoid the need to clamp and fix the blended yarn again every time you test it, which is not only time-consuming and labor-intensive, but also inefficient.

[0013] (2) The present invention utilizes the characteristic that the fixed ring can move cyclically under the drive of the chain, and sets a rack. When the fixed ring moves to start to move vertically downward, the gear and the rack will contact and form a meshing state during the downward movement of the fixed ring. When the fixed ring moves downward, the gear will rotate and drive the rotating block to rotate inside the fixed ring. When the rotating block rotates, the protruding block is squeezed to shrink upward, so that the hydraulic oil on the protruding block passes through the connecting groove 1, pushing the sliding protruding ring to extend outward to the arc-shaped groove, so as to limit the position of the sliding plate. After the rotating block rotates one circle, the protruding ring The block will continue to be stuck in the groove, and then the hydraulic oil will flow back, driving the sliding convex ring to reset. Through the operation of the above components, the blended yarn can be wound around the surface of the clamping column, making the clamping of the blended yarn tighter, avoiding looseness due to insufficient clamping during tensile performance testing, which affects the measurement results. The sliding plate is limited by the sliding convex ring to prevent the clamping column from popping outward under the action of the telescopic spring when the rotating block rotates to the vertical state of the two clamping columns, causing the blended yarn to be broken, making it impossible to perform the tensile performance test of the blended yarn this time.

[0014] (3) The present invention utilizes the above-mentioned characteristics that the clamping column will slide downward closely against the fixed groove block and gradually shrink inward to clamp the blended yarn. Two rubber transmission belts are provided, and the rubber transmission belts are sleeved on the clamping plate inside the fixed groove block. When the clamping column moves to the position where it is ready to move downward, the clamping column is opened outward by the action of the telescopic spring. In the process of the clamping column gradually moving downward, it contacts with the rubber transmission belt and gradually shrinks inward to clamp the blended yarn. Then, the rotating block is rotated by the rack to wrap the blended yarn around the surface of the clamping column. The clamping column then continues to move downward. It shrinks to the minimum value, at which time the clamping column continues to move downward with the blended yarn. Since the clamping column is tightly attached to the rubber transmission belt, the rubber transmission belt is also driven by the action of the ball when the clamping column moves downward, close to the clamping column and the clamping plate, and slides around the clamping plate. When the clamping column moves downward, the rubber transmission belt will also move closely together to prevent the blended yarn from being entangled on the surface of the clamping column and moving downward, generating friction with the surrounding area. In the friction that continues for a distance, the blended yarn may break due to severe wear, resulting in the inability to continue to carry out the tensile performance test.

[0015] (4) The present invention utilizes the characteristic that the clamping column can be extended and retracted inward and outward when moving under the action of the fixed groove block and the rubber transmission belt. When the clamping column moves to the position where it is ready to move downward, the clamping column is opened outward under the action of the telescopic spring 1. In the process of the clamping column gradually moving downward, it contacts with the rubber transmission belt and gradually retracts inward to clamp the blended yarn. When the clamping column retracts inward, the hydraulic oil inside the telescopic rod passes through the connecting groove 2, passes through the connecting hole, and enters one side of the clamping column. The telescopic rod generates negative pressure due to the flow of the internal hydraulic oil, and retracts inward, driving the sliding rod 2 to move inward, thereby preventing the blended yarn from being entangled on the telescopic rod and the sliding rod 2 during winding. When the clamping column moves downward to the bottom, the blended yarn is pulled in the tensile test. The clamping column loses contact with the fixed slot block and the rubber transmission belt, and is ejected outward by the action of the telescopic spring 1. When the clamping column moves outward, the hydraulic oil on one side of the clamping column is squeezed to pass through the connecting hole, through the connecting slot 2, and into the interior of the telescopic rod, so that when the telescopic rod is extended, it drives the sliding rod 2 to extend outward, and the protruding scraper block will always be in close contact with the surface of the clamping column under the action of the telescopic spring 3, so that when the sliding rod 2 is extended outward, it drives the surface of the clamping column to be scraped together, and the blended yarn broken on the clamping column is pushed outward to prevent it from continuing to be entangled on the clamping column and entering the interior of the chassis shell, so that the internal components of the equipment are entangled and stuck, affecting the normal operation, or entangled on the blended yarn being tested, so that the data of the tensile performance test is affected.

DETAILED DESCRIPTION

[0019] 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.

[0021] The circulating wire pulling mechanism 1 also includes a clamping column 105 slidably connected to the inner wall of the rotating block 104, a fixed bracket 106 is fixedly connected to the inner wall of the chassis shell 101, a motor 107 is fixedly connected to the top of the fixed bracket 106, a sprocket 108 is fixedly connected to the outer wall of the motor 107, and a chain 109 is meshingly connected to the outer wall of the sprocket 108. The fixed bracket 106 can ensure that the motor 107 can rotate normally during operation to avoid reversal and deviation during rotation. When the motor 107 is powered on, it drives the sprocket 108 to rotate, and then the rotation of the sprocket 108 can drive the chain 109 to rotate, thereby providing the main power source for the operation of the subsequent components.

[0022] The circulating wire pulling mechanism 1 also includes a fixed block 110 fixedly connected to the outer wall of the chain 109, a spring expansion block 111 is slidably connected to the inner wall of the fixed block 110, a protruding strip 112 is slidably connected to the inner wall of the chassis shell 101, a spring plate 113 is fixedly connected to the outer wall of the protruding strip 112, the outer wall of the spring plate 113 is slidably connected to the inner wall of the chassis shell 101, and a hydraulic pipe 114 is fixedly connected to the inner wall of the chassis shell 101. Since the fixed block 110 is fixed on the chain 109, when the chain 109 rotates, it will drive the fixed block 110 and the spring expansion block 111 to rotate together. When the fixed ring 103 moves downward, the sliding block 102 will contact the protruding strip 112 and squeeze the protruding strip 112 to shrink inward, so that the spring plate 113 pushes the hydraulic oil on the outside into the hydraulic pipe 114 to promote the operation of subsequent components.

[0023] The circulating wire pulling mechanism 1 also includes a U-shaped clamping rod 115 slidably connected to the inner wall of the hydraulic pipe 114, the outer wall of the U-shaped clamping rod 115 is slidably connected to the inner wall of the chassis shell 101, the outer wall of the chassis shell 101 is fixedly connected with a fixed groove block 116, the inner wall of the fixed ring 103 is slidably connected with a spring telescopic protrusion 117, the inner wall of the fixed ring 103 is fixedly connected with a hydraulic pipe 118, the outer wall of the fixed ring 103 is fixedly connected with a fixed block 119, and the fixed block 119 is fixedly connected with the outer wall of the fixed ring 103. The inner wall of the hydraulic pipe 114 is fixedly connected with the outer wall of the hydraulic pipe 118. The hydraulic oil in the hydraulic pipe 114 is pressurized to push the U-shaped clamping rod 115 to extend outward, thereby limiting the position of the fixed ring 103. When the fixed ring 103 stops moving, the tensile performance of the blended yarn is tested. As the U-shaped clamping rod 115 extends outward, the spring telescopic protrusion 117 will contact it and be pressurized to cause the hydraulic oil on the top to enter the fixed block 119 through the hydraulic pipe 118, thereby promoting the operation of subsequent components.

[0024] The circulating wire pulling mechanism 1 also includes a sliding rod 120 slidably connected to the inner wall of the fixed block 119, a sliding groove block 121 is slidably connected to the outer wall of the fixed ring 103, the outer wall of the sliding groove block 121 is fixedly connected to the outer wall of the sliding rod 120, the inner wall of the sliding groove block 121 is slidably connected to a spring telescopic bevel tooth 122, and the outer wall of the clamping column 105 is fixedly connected to a telescopic spring 123. When the chain 109 rotates, the sliding groove block 121 can be driven by the fixed block 110 and the spring telescopic block 111, and then the fixed ring 103 moves therewith. The blended yarn is firstly wound around the surface of the clamping column 105, and then the motor 107 is powered on. When the motor 107 is powered on, the chain is driven by the chain teeth 108. 109 rotates, and the chain 109 rotates to drive the fixed block 110 and the spring expansion block 111 to move. At this time, the spring expansion block 111 is stuck in the sliding slot block 121. When the spring expansion block 111 moves, it will drive the sliding slot block 121 and the fixed ring 103 to move. When the fixed ring 103 moves downward, the blended yarn wrapped on the surface of the clamping column 105 is pulled downward by the clamping column 105, so that the blended yarn is in a relatively tight and vertical downward state. When the fixed ring 103 continues to move downward, the other fixed ring 103 will also be driven by the chain 109 to rotate downward from the top sprocket 108 position. At this time, the clamping column 105 is in an outwardly opened state due to the action of the expansion spring 123. When the fixed ring 103 moves downward, the blended yarn in a relatively tight and vertically downward state will be located in the middle of the two clamping columns 105 of the other fixed ring 103. Then, when the other clamping column 105 moves downward, the clamping column 105 contacts the surface of the fixed groove block 116, moves downward closely against the surface of the fixed groove block 116, and gradually contracts inward to clamp the blended yarn between the two clamping columns 105, causing it to move downward. When the fixed ring 103 moves downward to the protruding strip 112, the sliding block 102 contacts the protruding strip 112 and squeezes the protruding strip 112 to shrink inward. The protruding strip 112 shrinks inward, squeezing the hydraulic oil on its outer side through the spring plate 113, so that the hydraulic oil pushes the U-shaped clamping rod 115 to move outward through the hydraulic pipe 114. The chain 109 is in a state of being unable to move the other fixed ring 103. The other fixed ring 103 is stuck by the U-shaped clamping rod 115 when it moves downward. The spring telescopic protrusion 117 contacts the U-shaped clamping rod 115 and contracts upward under pressure, so that the hydraulic oil on the spring telescopic protrusion 117 enters the fixed block 119 through the hydraulic pipe 118, and then pushes the sliding rod 120 to move outward, and drives the sliding groove block 121 to move outward together. At this time, the sliding groove block 121 loses contact with the spring telescopic block 111, and the chain 109 cannot drive the other fixed ring 103 to move when rotating. At this time, the other fixed ring 103 will be restricted by the U-shaped clamping rod 115 and cannot move, while the fixed ring 103 drives the blended yarn downward under the rotation of the chain 109.The tensile performance of the blended yarn is tested, and the blended yarn is finally torn off to end the test, and then the fixed ring 103 moves downward, so that the sliding block 102 loses contact with the protruding strip 112, and the spring plate 113 rebounds to drive the hydraulic oil in the hydraulic pipe 114 to flow back, so that the U-shaped clamping rod 115 retracts. At this time, the other fixed ring 103 will not be restricted by the clamping position, and the spring telescopic protrusion 117 rebounds to drive the hydraulic oil in 119 to flow back, and the sliding groove block 121 is reset to form a closed state. When the chain 109 rotates, it drives the fixed block 110 and the spring telescopic block 111 to move, so that the spring telescopic block 111 and the spring telescopic bevel gear 122 contacts, the spring telescopic bevel teeth 122 and the spring telescopic block 111 are compressed and retracted, and the spring telescopic block 111 is stuck in the sliding slot block 121, so that the chain 109 can continue to drive the fixing ring 103 to move, and the next tensile performance test is carried out. Through the operation of the above components, the tensile performance test of the blended yarn only needs to be wound around the surface of the clamping column 105 at the beginning of the test. After the equipment is started, the tensile performance test of the blended yarn can be repeated many times during operation, avoiding the need to clamp and fix the blended yarn again for each test, which is not only time-consuming and labor-intensive, but also inefficient.

[0025] For example 2, please refer to Figure 4 - Fig. 9The present invention is a tensile performance testing device for blended yarn processing. On the basis of the first embodiment, the fixed anti-wear mechanism 2 also includes a groove 204 opened on the outer wall of the rotating block 104, a protruding block 205 is slidably connected to the inner wall of the fixed ring 103, and a telescopic spring 206 is fixedly connected to the outer wall of the protruding block 205. A gear 207 is fixedly connected to the outer wall of the rotating block 104, and a sliding plate 208 is fixedly connected to the outer wall of the clamping column 105. The outer wall of the sliding plate 208 is slidably connected to the inner wall of the rotating block 104. Utilizing the characteristic that the above-mentioned fixed ring 103 can cyclically move under the drive of the chain 109, a rack 201 is set. When the fixed ring 103 moves to start to move vertically downward, the gear 207 will contact the rack 201 and form a meshing state during the downward movement of the fixed ring 103. When the fixed ring 103 moves downward, the gear 207 will rotate and drive the rotating block 104 to rotate inside the fixed ring 103. When the rotating block 104 rotates, the protruding block 205 is squeezed and retracted upward, so that the hydraulic oil on the protruding block 205 passes through the connecting groove 1 203, pushing the sliding protruding ring 202 to extend outward to the arc groove 209 to limit the position of the sliding plate 208. After the rotating block 104 rotates one circle, the protruding block 205 will continue to be stuck in the groove 204, and then the hydraulic oil will flow back to drive the sliding protruding ring 202 to reset. Through the operation of the above components, the blended yarn can be wound around the clamping column 1 The surface of 05 can make the clamping of the blended yarn tighter, so as to avoid looseness due to insufficient clamping during the tensile performance test, which affects the measurement result. The sliding plate 208 is limited by the sliding convex ring 202 to prevent the clamping column 105 from popping outward due to the telescopic spring 123 when the rotating block 104 is rotated to the vertical state of the two clamping columns 105, so that the blended yarn is broken and the tensile performance test of the blended yarn cannot be carried out.

[0026] The fixed anti-wear mechanism 2 also includes an arc-shaped groove 209 opened on the outer wall of the sliding plate 208, a clamping plate 210 is fixedly connected to the inner wall of the fixed groove block 116, a roller 211 is rotatably connected to the inner wall of the fixed groove block 116, a rubber transmission belt 212 is slidably connected to the outer wall of the roller 211, and a ball 213 is rotatably connected to the inner wall of the clamping plate 210. By utilizing the above-mentioned characteristics that the clamping column 105 will slide downward close to the fixed groove block 116 and gradually shrink inward to clamp the blended yarn, two rubber transmission belts 212 are set, and the rubber transmission belts 212 are sleeved on the clamping plate 210 inside the fixed groove block 116. When the clamping column 105 moves to the position where it starts to move downward, the clamping column 105 is opened outward by the action of the telescopic spring 123. In the process of the clamping column 105 gradually moving downward, it contacts with the rubber transmission belt 212 and gradually moves inward. The blended yarn is clamped by contraction, and then the rotating block 104 is rotated through the rack 201 to wrap the blended yarn around the surface of the clamping column 105. The clamping column 105 continues to move downward and will shrink to the minimum value. At this time, the clamping column 105 continues to move downward with the blended yarn. Since the clamping column 105 is tightly attached to the rubber transmission belt 212, the rubber transmission belt 212 is also driven by the action of the ball 213 during the downward movement of the clamping column 105, and is close to the clamping column 105 and the clamping plate 210, and slides around the clamping plate 210, so that when the clamping column 105 moves downward, the rubber transmission belt 212 will also move closely together, avoiding the blended yarn from being entangled on the surface of the clamping column 105 and moving downward, and generating friction with the surroundings. In the friction that continues for a certain distance, the blended yarn is accidentally broken due to severe wear, resulting in the problem that the tensile performance test cannot be further realized.

[0027] The wire breaking and disengaging mechanism 3 also includes a sliding rod 2 304 fixedly connected to the outer wall of the telescopic rod 303, the outer wall of the sliding rod 2 304 is slidably connected to the inner wall of the rotating block 104, the inner wall of the sliding rod 2 304 is slidably connected with a protruding scraping block 305, the outer wall of the protruding scraping block 305 is slidably connected to the outer wall of the clamping column 105, and the outer wall of the protruding scraping block 305 is fixedly connected with a telescopic spring 306. The clamping column 105 is subjected to the action of the fixed groove block 116 and the rubber transmission belt 212, and can be extended inward and outward when moving. When the clamping column 105 moves to the position where it is ready to move downward, the clamping column 105 is opened outward by the action of the telescopic spring 123. In the process of the clamping column 105 gradually moving downward, it contacts the rubber transmission belt 212 and gradually contracts inward to clamp the blended yarn. When the clamping column 105 contracts inward, the hydraulic oil inside the telescopic rod 303 passes through the connecting groove 2 302, passes through the connecting hole 301, and enters one side of the clamping column 105. The telescopic rod 303 generates negative pressure due to the flow of the internal hydraulic oil, contracts inward, and drives the sliding rod 2 304 inward. The first and second sliding rods 304 are connected to the clamping column 105, and the second and third sliding rods 304 are connected to the clamping column 105. When the clamping column 105 moves downward to the bottom, the blended yarn is broken in the tensile test, and the clamping column 105 loses contact with the fixed groove block 116 and the rubber transmission belt 212, and is ejected outward by the action of the telescopic spring 123. When the clamping column 105 moves outward, the hydraulic oil on one side of the clamping column 105 is squeezed to pass through the connecting hole 301, through the connecting groove 302, and into the interior of the telescopic rod 303, so that the telescopic rod 303 is extended. The sliding rod 2 304 is driven to extend outward, and the protruding scraper block 305 is always closely attached to the surface of the clamping column 105 under the action of the telescopic spring 306, so that when the sliding rod 2 304 is extended outward, it drives the surface of the clamping column 105 to be scraped, and the blended yarn broken on the clamping column 105 is pushed outward to prevent it from continuing to be entangled on the clamping column 105 and entering the interior of the chassis shell 101, so that the internal components of the equipment are entangled and stuck, affecting the normal operation, or entangled on the blended yarn being tested, so that the data of the tensile performance test is affected.

[0028] A specific application of this embodiment is: before using the device, first install the device at the required position, turn on the power of the motor 107, first wind the blended yarn on the surface of the clamping column 105, and then power on the motor 107. When the motor 107 is powered on, the chain 109 is driven to rotate by the sprocket 108, and the rotation of the chain 109 drives the fixed block 110 and the spring expansion block 111 to move. At this time, the spring expansion block 111 is stuck in the sliding groove block 121. When the spring expansion block 111 moves, it will drive the sliding groove block 121 and the fixed ring 103 to move. When the fixed ring 103 moves downward, the blended yarn wrapped on the surface of the clamping column 105 is pulled downward by the clamping column 105, so that the blended yarn is in a relatively When the fixing ring 103 is continuously moved downward, the other fixing ring 103 will also be driven by the chain 109 to rotate downward from the top sprocket 108 position. At this time, the clamping column 105 is in an outwardly opened state under the action of the telescopic spring 123. When the other fixing ring 103 is moved downward, the blended yarn in a relatively tight and vertically downward state will be in the middle of the two clamping columns 105 of the other fixing ring 103. Then, when the other clamping column 105 moves downward, the clamping column 105 contacts the surface of the fixed groove block 116, moves downward closely against the surface of the fixed groove block 116, and gradually contracts inward to clamp the blended yarn between the two clamping columns 105, so that it moves downward. When the spring plate 113 is pressed against the U-shaped clamping rod 115, the hydraulic oil on the U-shaped clamping rod 115 is pushed outwards through the hydraulic pipe 114 to limit the position of the other fixed ring 103. The other fixed ring 103 is stuck by the U-shaped clamping rod 115 during the downward movement. The spring telescopic protrusion 117 is pressed against the U-shaped clamping rod 115 and is pushed upwards to make the hydraulic oil on the spring telescopic protrusion 117 enter the fixed block 119 through the hydraulic pipe 118, and then push the sliding rod 120 to move outwards, and drive the sliding slot block 121 to move outwards together. The sliding slot block 121 loses contact with the spring expansion block 111, and the chain 109 cannot drive the other fixed ring 103 to move when rotating. At this time, the other fixed ring 103 will be restricted by the U-shaped clamping rod 115 and cannot move. The fixed ring 103 drives the blended yarn downward under the rotation of the chain 109 to test the tensile performance of the blended yarn, and finally the blended yarn is torn off to end the test. Then the fixed ring 103 moves downward, causing the sliding block 102 to lose contact with the protruding strip 112. The spring plate 113 rebounds and drives the hydraulic oil in the hydraulic pipe 114 to flow back, allowing the U-shaped clamping rod 115 to retract. At this time, the other fixed ring 103 will not be restricted by the clamping position, and the spring expansion protrusion 117 rebounds and drives the hydraulic oil in 119 to flow back.The sliding slot block 121 is reset to form a closed state. When the chain 109 rotates, it drives the fixed block 110 and the spring expansion block 111 to move, so that the spring expansion block 111 contacts the spring expansion bevel teeth 122. The spring expansion bevel teeth 122 and the spring expansion block 111 are compressed and retracted, and the spring expansion block 111 is stuck inside the sliding slot block 121, so that the chain 109 can continue to drive the fixed ring 103 to move, and the next tensile performance test is carried out. Through the operation of the above components, the tensile performance test of the blended yarn only needs to be wound around the surface of the clamping column 105 at the beginning of the test. After the equipment is started, the tensile performance test of the blended yarn can be repeated many times during operation, avoiding the need to clamp and fix the blended yarn again for each test, which is not only time-consuming and labor-intensive, but also inefficient.

[0029] Taking advantage of the fact that the fixed ring 103 can move circularly under the drive of the chain 109, a rack 201 is provided. When the fixed ring 103 moves to start to move vertically downward, the gear 207 and the rack 201 are in contact and meshed state during the downward movement of the fixed ring 103. When the fixed ring 103 moves downward, the gear 207 is rotated and the rotating block 104 is driven to rotate inside the fixed ring 103. When the rotating block 104 rotates, the protruding block 205 is squeezed to shrink upward, so that the hydraulic oil on the protruding block 205 passes through the connecting groove 1 203, pushing the sliding protruding ring 202 to extend outward to the arc groove 209, so as to press the sliding plate 208. The positioning is limited, and after the rotating block 104 rotates one circle, the protruding block 205 will continue to be stuck in the groove 204, and then the hydraulic oil will flow back to drive the sliding convex ring 202 to reset. Through the operation of the above components, the blended yarn can be wound around the surface of the clamping column 105, so that the clamping of the blended yarn is tighter, and looseness due to insufficient clamping during the tensile performance test is avoided, which affects the measurement result. The sliding convex ring 202 is used to limit the position of the sliding plate 208 to prevent the clamping column 105 from popping outward under the action of the telescopic spring 123 when the rotating block 104 rotates to the vertical state of the two clamping columns 105, so that the blended yarn The rubber transmission belts 212 are set to be sleeved on the clamping plate 210 inside the fixed slot block 116. When the clamping column 105 moves to the position where it is ready to move downward, the clamping column 105 is opened outward by the telescopic spring 123. In the process of the clamping column 105 gradually moving downward, it contacts the rubber transmission belt 212 and gradually contracts inward to clamp the blended yarn. Then, the rotating block 104 is rotated by the rack 201 to wrap the blended yarn around the surface of the clamping column 105. The clamping column 105 continues to move downward and contracts to the minimum value. At this time, the clamping column 105 continues to move downward with the blended yarn. Since the clamping column 105 is tightly attached to the rubber transmission belt 212, when the clamping column 105 moves downward, the rubber transmission belt 212 is also driven by the ball 213 to slide closely against the clamping column 105 and the clamping plate 210 around the clamping plate 210. When the clamping column 105 moves downward, the rubber transmission belt 212 also moves closely together to prevent the blended yarn from being entangled on the surface of the clamping column 105 and moving downward, and generating friction with the surroundings. In the friction that continues for a certain distance, the blended yarn may break due to severe wear, resulting in the inability to continue to carry out the tensile performance test.

[0030] By utilizing the characteristic that the clamping column 105 can be extended and retracted inwards and outwards under the action of the fixed groove block 116 and the rubber transmission belt 212 during movement, when the clamping column 105 moves to the position where it starts to move downward, the clamping column 105 is opened outwards under the action of the telescopic spring 123. In the process of the clamping column 105 gradually moving downwards, it contacts the rubber transmission belt 212 and gradually retracts inwards to clamp the blended yarn. When the clamping column 105 retracts inwards, the hydraulic oil inside the telescopic rod 303 passes through the connecting groove 2 302, passes through the connecting hole 301, and enters one side of the clamping column 105. The telescopic rod 303 generates negative pressure due to the flow of the internal hydraulic oil, retracts inwards, and drives the sliding rod 2 304 to move inwards, so as to prevent the blended yarn from being entangled on the telescopic rod 303 and the sliding rod 2 304 during winding. When the clamping column 105 moves downwards to the bottom, the blended yarn is broken in the tensile test, and the clamping Column 105 loses contact with fixed slot block 116 and rubber transmission belt 212, and pops outward under the action of telescopic spring 123. When clamping column 105 moves outward, the hydraulic oil on one side of clamping column 105 is squeezed to pass through connecting hole 301, through connecting slot 2 302, and enters the interior of telescopic rod 303, so that when telescopic rod 303 is extended, it drives sliding rod 2 304 to extend outward. The protruding scraper block 305 is always in close contact with the surface of clamping column 105 under the action of telescopic spring 306, so that when sliding rod 2 304 is extended outward, it drives the surface of clamping column 105 to be scraped together, and the blended yarn broken on clamping column 105 is pushed outward to prevent it from continuing to be entangled on clamping column 105 and entering the interior of chassis shell 101, so that the internal components of the equipment are entangled and stuck, affecting normal working operation, or entangled on the blended yarn being tested, so that the data of tensile performance test is affected.
