Description

Technical Field

[0001] The invention belongs to the technical field of textile machinery and relates to a replaceable textile rubber ring component which can operate continuously. Background Art

[0002] Textile rubber products are used for rubber accessories of textile machinery; there are textile drafting aprons, textile rubber rollers and hoses, textile leather rollers, textile rubber tape knots, textile spindle belts and other varieties; textile drafting aprons are referred to as textile aprons. Textile aprons are generally mounted on the outside of rubber rollers to create a friction boundary with the rollers, which are used to pull and stretch the textile yarns. The rollers are generally powered, and the textile aprons are driven to rotate by the friction force.

[0003] In the actual production process, the textile rubber ring and the roller stretch and pull the yarn through friction. As the use time increases, the textile rubber ring is seriously worn and needs to be stopped to replace the textile rubber ring. Moreover, the spinning equipment generally has multiple textile rubber rings. Each replacement of the textile rubber ring takes a long time, which reduces production efficiency.

[0004] Based on this, we designed a replaceable textile apron assembly that operates continuously. Summary of the invention

[0005] The purpose of the present invention is to address the above-mentioned problems in the prior art and to propose a sustainably operable replaceable textile rubber ring assembly. The technical problem to be solved by the device is: how to achieve non-stop replacement of textile rubber rings and improve production efficiency.

[0006] The purpose of the present invention can be achieved by the following technical solutions:

[0007] The invention relates to a replaceable textile rubber ring assembly which can be operated sustainably, comprising an extension arm, a sliding plate, a rotating rubber roller, an auxiliary rubber roller and an rubber ring body, wherein the extension arm is mounted on a textile equipment frame, and a roller is also mounted on the textile equipment frame, a sliding mechanism is arranged at a side end of the extension arm, the sliding plate is connected to the sliding mechanism, the rotating rubber roller is rotatably arranged on the sliding plate, and two symmetrically distributed sliding grooves are arranged on both sides of the sliding plate, support rods are slidably arranged in the sliding grooves, the rubber ring body is sleeved on the outer sides of the two support rods and the rotating rubber roller, and the rubber ring body is abutted against the roller below, a tensioning mechanism for tensioning the rubber ring body is arranged on one of the support rods, two symmetrically distributed fixed plates are fixed below the extension arm, an arc-shaped sliding groove is arranged on the fixed plate, and the auxiliary rubber roller is slidably arranged in the arc-shaped sliding groove at a corresponding position, a movable long groove is arranged at the upper end of the extension arm, and a handle is slidably arranged in the movable long groove, a lifting mechanism for lifting the sliding plate is arranged inside the extension arm, and the handle is connected to the lifting mechanism, a transmission mechanism for moving the auxiliary rubber roller is arranged on the fixed plate, and the transmission mechanism is connected to the lifting mechanism.

[0008] The working principle of the present invention is as follows: In actual use, the rubber ring body is sleeved outside two support rods and a rotating rubber roller. The rubber ring body is tightened by a tensioning mechanism. Moreover, the lower end of the rubber ring body is clamped between the rotating rubber roller and the roller. The spinning is located between the rubber ring body and the roller. When the roller rotates, the rotating rubber roller presses the rubber ring body against the roller, and drives the textile rubber ring body and the rotating rubber roller to rotate through friction, so as to traction or stretch the spinning. When the rubber ring body needs to be replaced, the operator pushes the handle along the moving long groove to the other side. Under the action of the lifting mechanism, the two support rods are driven to lift upward along the sliding notch. After the support rods are lifted to the uppermost end of the sliding notch, the sliding plate is driven to lift upward. While the support rods are lifting upward along the sliding notch, the transmission mechanism will drive the two auxiliary rubber rollers to move closer to the middle along the arc-shaped chute and abut against the roller, playing the same role as the rubber ring body. Then the sliding plate will move upward. When the sliding plate moves upward, the rotating rubber roller will rise and move away from the roller. At this time, the operator can remove the rubber ring body and replace it with a new one. Then the handle is reset. At this time, the sliding plate first slides down, pressing the rotating rubber roller, the rubber ring body and the roller against each other. Then the two auxiliary rubber rollers return to both sides and at the same time the two support rods move downward, and the newly replaced rubber ring body and the roller can continue to traction and stretch the spinning, without the need to stop the equipment, and the rubber ring body can be replaced at any time, improving the production efficiency.

[0009] The sliding mechanism includes two positioning bars and two T-shaped blocks. The positioning bars are fixed at the side ends of the extension arms. The sliding plate is slidably arranged between the two positioning bars, and two symmetrically distributed parallel grooves are formed on the sliding plate. The T-shaped blocks are fixed at the side ends of the extension arms, and the T-shaped blocks are located in the parallel grooves at the corresponding positions.

[0010] With the above structure, the two positioning bars can limit the sliding direction of the sliding plate, and the two T-shaped blocks can further limit the sliding direction of the sliding plate, and can prevent the sliding plate from bending and deforming outward.

[0011] The sliding mechanism further includes a limiting spring and a fixing block. The fixing block is fixed at the side end of the sliding plate, and the fixing block is located at the lower end of the parallel groove at the corresponding position. The limiting spring is fixed between the fixing block and the T-shaped block at the corresponding position.

[0012] With the above structure, under the action of the limiting spring, when the support rod slides upward, the sliding plate will not move upward following the support rod. When the support rod moves upward to the uppermost end of the sliding notch, the sliding plate will be driven to move upward, ensuring the moving sequence of the sliding plate and the support rod, and preventing the rubber ring body from separating from the roller when the auxiliary rubber roller has not contacted the roller, resulting in the interruption of the traction force.

[0013] The lifting mechanism includes two threaded rods and a transmission belt. Vertical grooves aligned with the sliding notches are formed at the side ends of the extension arm. A communication cavity is formed inside the extension arm, and both ends of the communication cavity communicate with the two vertical grooves. Two right-angled plates are fixed below the extension arm, and the two right-angled plates are respectively located directly below the two vertical grooves. The two threaded rods are respectively located in the two vertical grooves, and both ends of the threaded rods are rotatably connected to the right-angled plates and the inner wall of the communication cavity. A first pulley is also rotatably arranged on the inner wall of the communication cavity. A second pulley is connected to the upper end of one of the threaded rods. The transmission belt is installed between the first pulley and the second pulley, and the first pulley is in transmission connection with the other threaded rod through a gear pair. The moving long groove is located at the upper end of the communication cavity, and the lower end of the handle is fixed to the transmission belt. A threaded hole is formed at one end of the support rod, and the support rod is in threaded connection with the corresponding threaded rod.

[0014] With the above structure, when the operator pushes the handle, the transmission belt drives the first pulley and the second pulley to rotate in the same direction. Through the transmission of the gear pair, the rotation directions of the two threaded rods are symmetrical, driving the two support rods to move upward. When the support rods move upward to the uppermost end of the sliding notch, the sliding plate will be driven to lift upward.

[0015] The lifting mechanism further includes a fixing component. The fixing component includes a first torsion shaft and an L-shaped rod. The first torsion shaft is connected to the side end of the handle, and the L-shaped rod is connected to the first torsion shaft. Two limiting grooves are formed at the upper end of the extension arm, and the two limiting grooves are respectively located at the side edges of both ends of the moving long groove. The lower end of the L-shaped rod is located inside the limiting groove.

[0016] With the above structure, when the operator pushes the handle, the upper end of the L-shaped rod needs to be pressed to move the lower end of the L-shaped rod out of the limiting groove, and then the handle can be moved, preventing the sliding plate and the support rod from loosening when the operator replaces the rubber ring body or during the normal use of the rubber ring body, which affects the spinning quality.

[0017] The transmission mechanism includes a first bevel gear, a second bevel gear and a swing rod. The first bevel gear is fixed to the lower end of the threaded rod. The second bevel gear is rotatably arranged at the side end of the right-angled plate, and the second bevel gear meshes with the first bevel gear. A second torsion shaft is connected to the rotating shaft of the second bevel gear, and a rotating groove is formed at the end of the second torsion shaft. The swing rod is slidably arranged in the rotating groove, and a connecting rod is fixed to one end of the swing rod. The connecting rod passes through the corresponding arc-shaped chute. The auxiliary rubber roller is rotatably arranged on the connecting rod. Two limiting retaining rings are fixed on the connecting rod, and the two limiting retaining rings are respectively located on both sides of the fixing plate.

[0018] With the above structure, when the threaded rod rotates, it will drive the first bevel gear and the second bevel gear to rotate. The second bevel gear will drive the swing rod to rotate, and the swing rod will drive the connecting rod and the auxiliary rubber roller to move along the arc-shaped chute. Moreover, the swing rod can slide, so it can adapt to different distances between the connecting rod and the second torsion shaft. When the connecting rod moves to the other end of the arc-shaped chute and abuts against the roller, the second bevel gear can continue to rotate against the pressure of the second torsion shaft without hindering the rotation of the threaded rod.

[0019] The tensioning mechanism includes a cross plate and a tensioning spring. One of the support rods is divided into a support part and a connecting part. The cross plate is fixed on the connecting part, and a plurality of transverse grooves are formed in the cross plate. A plurality of sliders are fixed on the support part, and the sliders are slidably arranged in the transverse grooves. The tensioning spring is located inside the transverse grooves, and both ends of the tensioning spring abut against the end side walls of the transverse grooves and the sliders respectively.

[0020] With the above structure, the support part can move along the cross plate under the combined action of the slider and the transverse groove. Under the action of the tensioning spring, the support part has a tendency to move away from the rotating rubber roller, so that the support part can support the rubber ring body from the inside and tension the rubber ring body.

[0021] Compared with the prior art, the sustainable operation replaceable textile rubber ring assembly has the following advantages:

[0022] Through the sliding plate, the auxiliary rubber roller, the lifting mechanism, the transmission mechanism and the support rod, the rubber ring body can be replaced without stopping the machine. The replacement operation is simple, and the spinning equipment can run continuously, improving the production efficiency.

[0023] Through the tensioning mechanism, the rubber ring body is tensioned. During the movement of the support rod, the position of the rubber ring body is stabilized, and it is convenient for the operator to remove and install the rubber ring body.

[0024] Through the fixing component, the stability of the handle is improved, preventing the sliding plate and the support rod from moving when the operator replaces the rubber ring body or when the rubber ring body is in normal use, which affects the spinning quality.

The limit spring 305 is fixed between the fixed block 304 and the T-shaped block 303 at the corresponding position; under the action of the limit spring 305, when the support rod 6 slides upward, the sliding plate 2 will not move upward with the support rod 6. When the support rod 6 moves upward to the uppermost end of the sliding groove 5, it will drive the sliding plate 2 to move upward, thereby ensuring the movement sequence of the sliding plate 2 and the support rod 6, and preventing the rubber ring body 8 from being separated from the roller when the auxiliary rubber roller 11 is not in contact with the roller, resulting in interruption of traction.

[0044] The above fixing methods are all the most commonly used fixed connection methods in the field, such as welding, bolt connection, etc.

[0045] The working principle of the present invention:

[0046] In actual use, the rubber ring body 8 is sleeved outside the two support rods 6 and the rotating rubber roller 4. The support portion 601 can move along the cross plate 701 under the cooperation of the slider 703 and the transverse groove 702. Under the action of the tension spring 704, the support portion 601 has a tendency to move away from the rotating rubber roller 4, so that the support portion 601 can support the rubber ring body 8 from the inside, tighten the rubber ring body 8. Moreover, the lower end of the rubber ring body 8 is clamped between the rotating rubber roller 4 and the roller. The spinning is located between the rubber ring body 8 and the roller. When the roller rotates, the rotating rubber roller 4 presses the rubber ring body 8 against the roller, and drives the textile rubber ring body 8 and the rotating rubber roller 4 to rotate through friction, so as to traction or stretch the spinning. When the rubber ring body 8 needs to be replaced, the operator presses the upper end of the L-shaped rod 1410, moves the lower end of the L-shaped rod 1410 out of the limit groove 1411, and then pushes the handle 13 along the moving long groove 12 to the other side. The transmission belt 1407 drives the first belt pulley 1406 and the second belt pulley 1405 to rotate in the same direction. Through the transmission of the gear pair 1408, the rotation directions of the two threaded rods 1404 are symmetrical, driving the two support rods 6 to move upward. When the support rod 6 moves upward to the uppermost end of the sliding groove opening 5, it will drive the sliding plate 2 to move upward. When the threaded rod 1404 rotates, it will drive the first bevel gear 1501 and the second bevel gear 1502 to rotate. The second bevel gear 1502 will drive the swing rod 1504 to rotate. The swing rod 1504 will drive the connecting rod 1505 and the auxiliary rubber roller 11 to move along the arc-shaped chute 10, driving the two auxiliary rubber rollers 11 to move closer to the middle along the arc-shaped chute 10 and abut against the roller. And the swing rod 1504 can slide, so it can adapt to the different distances between the connecting rod 1505 and the second torsion shaft 1503. When the connecting rod 1505 moves to the other end of the arc-shaped chute 10 and abuts against the roller, the second bevel gear 1502 can continue to rotate against the pressure of the second torsion shaft 1503 without hindering the rotation of the threaded rod 1404. After that, the sliding plate 2 will move upward. When the sliding plate 2 moves upward, the rotating rubber roller 4 will rise and move away from the roller. At this time, the operator can remove the rubber ring body 8 and replace it with a new rubber ring body 8, and then reset the handle 13 with the same operation. At this time, the sliding plate 2 first slides down, pressing the rotating rubber roller 4, the rubber ring body 8 and the roller against each other, and then the two auxiliary rubber rollers 11 reset to both sides and at the same time the two support rods 6 move downward, so that the newly replaced rubber ring body 8 and the roller can continue to be used to traction and stretch the spinning. There is no need to stop the equipment, and the rubber ring body 8 can be replaced at any time, improving the production efficiency.

[0047] The above has described the preferred embodiments of the present patent in detail. However, the present patent is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the gist of the present patent.
