Description

Technical Field

[0001] This utility model relates to the field of polyester low-elasticity yarn processing technology, specifically a shearing mechanism for processing polyester low-elasticity yarn. Background Technology

[0002] Polyester low-elasticity yarn is a type of textured yarn of polyester chemical fiber. It is made from polyester chips as raw material, using high-speed spinning of pre-oriented polyester yarn, and then processing through drawing and false twisting. It has the characteristics of short process, high efficiency, and good quality. In addition to the general characteristics of polyester such as high breaking strength and elastic modulus, excellent heat setting, good resilience, heat resistance, light resistance, strong corrosion resistance, easy washing and quick drying, it also has the characteristics of high bulkiness, good heat insulation, comfortable hand feel and soft luster.

[0003] Polyester low-elasticity yarn has a wide range of applications in the textile industry, and different textiles have different requirements for the length, specifications, etc. of polyester low-elasticity yarn. Through a shearing mechanism, polyester low-elasticity yarn can be customized according to customer needs to meet the diverse demands of the market. Current shearing methods include hydraulic cylinders driving the cutting blade to move up and down reciprocally to continuously cut the polyester low-elasticity yarn, or using a cam linkage mechanism to drive the cutting blade to move up and down reciprocally to continuously cut the polyester low-elasticity yarn.

[0004] Therefore, in the existing technology, the cutting length of the shearing mechanism for processing polyester low-elasticity yarn is fixed during the continuous cutting process of polyester low-elasticity yarn, making it difficult to adjust the cutting length of polyester low-elasticity yarn according to the needs, which is inconvenient to use. Utility Model Content

[0005] The purpose of this invention is to provide a shearing mechanism for processing polyester low-elasticity yarn, which has the effect of facilitating the adjustment of the cutting length of polyester low-elasticity yarn, eliminating the need for repeated adjustments, making it easy to use, and providing high cutting precision.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a shearing mechanism for processing polyester low-elasticity yarn, comprising a base plate, a conveyor and a fixed frame located on the outer right side of the conveyor mounted on the upper end face of the base plate, a cutting table mounted on the right end of the conveyor, a motor mounted on the upper end face of the fixed frame, the output end of the motor penetrating through the upper end face of the fixed frame and mounted with an eccentric wheel, a movable seat disposed at the bottom of the eccentric wheel, a cutting blade located directly above the cutting table mounted on the bottom of the movable seat, and two left-right distributed fixed plates mounted on the upper end face, a lead screw mounted between the two fixed plates, a slider threadedly connected to the outer side wall of the lead screw, and a connecting rod mounted between the upper end face of the slider and the eccentric wheel via a universal joint.

[0007] In order to press the polyester low elasticity yarn with the pressure roller and transport it with the conveyor at the same time, as a preferred shearing mechanism for processing polyester low elasticity yarn according to this utility model, a fixed frame is installed on the right end of the upper end face of the conveyor. The upper end face of the fixed frame is threaded with a screw. The bottom of the screw is rotatably connected to a mounting bracket that is slidably connected to the inner side wall of the fixed frame. The pressure roller is rotatably connected inside the mounting bracket.

[0008] To facilitate the rotation of the lead screw and the movement of the slider, in a preferred embodiment of the shearing mechanism for processing polyester low-elasticity yarn according to this utility model, the bottom of the slider abuts against the upper surface of the moving seat, and the right end of the lead screw passes through the fixed plate located on the right side and is equipped with a handwheel.

[0009] In order to make the moving seat move stably, as a preferred shearing mechanism for processing polyester low elastic yarn according to this utility model, the outer side walls of the two legs of the fixed frame are movably sleeved with sliding sleeves fixedly installed on the outer side walls of the moving seat, and damping springs are movably sleeved on the outer side walls of the two legs of the fixed frame below the two sliding sleeves.

[0010] In order to adjust the position of the slider, a scale is preferably provided on the upper end surface of the moving seat as a preferred shearing mechanism for processing polyester low elastic yarn according to the present invention.

[0011] To facilitate the collection of cut polyester low-elasticity yarn, a collection box is preferably provided below the moving seat in the preferred embodiment of the shearing mechanism for processing polyester low-elasticity yarn according to this utility model.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This utility model adjusts the position of the mounting frame and pressure roller by rotating the screw, so that the pressure roller presses the polyester low elastic yarn while cooperating with the conveyor to transport it. The motor drives the eccentric wheel to rotate, which in turn drives the connecting rod to rotate and swing. This causes the connecting rod to drive the slider, moving seat, cutting blade and two sliding sleeves to move up and down repeatedly, so that the cutting blade cuts the polyester low elastic yarn at equal intervals.

[0014] By turning the handwheel, the lead screw rotates, driving the slider to move. The slider's position is adjusted using a scale, thereby adjusting the travel of the moving seat and the cutting blade. This allows for easy adjustment of the cutting length of the polyester low-elasticity yarn, eliminating the need for repeated adjustments. It is convenient to use and offers high cutting precision.

[0019] Please see Figures 1 to 3 A shearing mechanism for processing polyester low-elasticity yarn includes a base plate 1. A conveyor 2 and a fixed frame 3 located on the outer right side of the conveyor 2 are mounted on the upper end of the base plate 1. A cutting table 201 is mounted on the right end of the conveyor 2. A motor 301 is mounted on the upper end of the fixed frame 3. The output end of the motor 301 passes through the upper end of the fixed frame 3 and is mounted with an eccentric wheel 302. A movable seat 5 is provided at the bottom of the eccentric wheel 302 and below the eccentric wheel 302. A cutting blade 501 located directly above the cutting table 201 is mounted at the bottom of the movable seat 5. Two left and right fixed plates 6 are mounted on the upper end of the movable seat 5. A lead screw 601 is installed between the two fixed plates 6. A slider 602 is threadedly connected to the outer side of the lead screw 601. A connecting rod 4 is installed between the upper end of the slider 602 and the eccentric wheel 302 through a universal joint.

[0020] In this embodiment: The polyester low-elasticity yarn to be cut is placed at the left end of the conveyor belt of the conveyor 2. Then, the conveyor 2 transports the polyester low-elasticity yarn. At the same time, the screw 8 is rotated to adjust the position of the mounting frame 801 and the pressure roller 802. When the polyester low-elasticity yarn moves to the bottom of the pressure roller 802, the pressure roller 802 presses the polyester low-elasticity yarn and transports it in conjunction with the conveyor 2. By starting the motor 301, the eccentric wheel 302 can be driven to rotate. The eccentric wheel 302 drives the connecting rod 4 to rotate and swing. This causes the connecting rod 4 to drive the slider 602, the moving seat 5, the cutting blade 501, and the two sliding sleeves 502 to move up and down reciprocally. This allows the cutting blade 501 to cut the polyester low-elasticity yarn at equal intervals.

[0021] When it is necessary to adjust the cutting length of polyester low elastic yarn, the handwheel is turned to make the lead screw 601 rotate and drive the slider 602 to move. The position of the slider 602 is adjusted by using a scale, thereby adjusting the reciprocating stroke of the moving seat 5 and the cutting blade 501, which makes it easy to adjust the cutting length of polyester low elastic yarn.

[0022] As a technical optimization of this utility model, a fixed frame 7 is installed on the right end of the upper surface of the conveyor 2. A screw 8 is threaded through and connected to the upper surface of the fixed frame 7. The bottom of the screw 8 is rotatably connected to a mounting bracket 801 that is slidably connected to the inner side wall of the fixed frame 7. A pressure roller 802 is rotatably connected inside the mounting bracket 801.

[0023] In this embodiment: by rotating the screw 8, the positions of the mounting frame 801 and the pressure roller 802 can be adjusted so that the pressure roller 802 presses the polyester low elastic yarn while cooperating with the conveyor 2 to transport it.

[0024] As a technical optimization of this utility model, the bottom of the slider 602 abuts against the upper surface of the movable seat 5, and the right end of the lead screw 601 passes through the fixed plate 6 located on the right side and is equipped with a handwheel.

[0025] In this embodiment: by rotating the handwheel, the lead screw 601 rotates, causing the slider 602 to move to the left or right.

[0026] As a technical optimization of this utility model, the outer side walls of the two legs of the fixed frame 3 are movably sleeved with sliding sleeves 502 that are fixedly installed on the outer side walls of the movable seat 5, and damping springs that are movably sleeved on the outer side walls of the two legs of the fixed frame 3 are provided below the two sliding sleeves 502.

[0027] In this embodiment: by setting up sliding sleeves 502, when the moving seat 5 moves, it can drive the two sliding sleeves 502 to move along the legs of the two fixed frames 3 respectively. During the movement of the two sliding sleeves 502, the damping spring can buffer the two sliding sleeves 502 (when the moving seat 5 drives the cutting blade 501 to descend and cut, the sliding sleeves 502 only contact the damping spring, and the damping spring buffers the impact force of the sliding sleeves 502).

[0028] As a technical optimization of this utility model, a scale is provided on the upper surface of the movable seat 5.

[0029] In this embodiment: A scale is provided to facilitate the adjustment of the position of the slider 602.

[0030] As a technical optimization of this utility model, a collection box 9 is provided below the movable seat 5.

[0031] In this embodiment: the cut polyester low-elasticity yarn is collected through the collection box 9.

[0032] Working principle: First, when using this device, connect it to an external power source and connect it to an external control panel. Then, place the polyester low-elasticity yarn to be cut at the left end of the conveyor belt of conveyor 2. Then, start the conveyor 2 through the control panel so that the conveyor 2 can transport the polyester low-elasticity yarn. At the same time, rotate the screw 8 to adjust the position of the mounting frame 801 and the pressure roller 802 so that when the polyester low-elasticity yarn moves under the pressure roller 802, the pressure roller 802 presses the polyester low-elasticity yarn and transports it in conjunction with the conveyor 2. By starting the motor 301, the eccentric wheel 302 can be driven to rotate, so that the eccentric wheel 302 drives the connecting rod 4 to rotate and swing, causing the connecting rod 4 to drive the slider 602, the moving seat 5, the cutting blade 501 and the two sliding sleeves 502 to move up and down reciprocally, so that the cutting blade 501 cuts the polyester low-elasticity yarn at equal intervals.

[0033] When it is necessary to adjust the cutting length of polyester low-elasticity yarn, the moving seat 5 is moved to the initial position and the eccentric wheel 302 is rotated to the initial position. By turning the handwheel, the lead screw 601 is rotated, driving the slider 602 to move. The position of the slider 602 is adjusted by using a scale. When the motor 301 drives the eccentric wheel 302 to rotate, the connecting rod 4 drives the slider 602, the moving seat 5, and the cutting blade 501 to move up and down reciprocally. The stroke of the moving seat 5 and the cutting blade 501 can be adjusted, so as to facilitate the adjustment of the cutting length of polyester low-elasticity yarn. Finally, after the polyester low-elasticity yarn is cut, it can fall into the collection box 9 for collection.

[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
