Description

Technical Field

[0001] This utility model relates to the field of electronic single yarn strength machine technology, specifically to a cabinet-type electronic single yarn strength machine for mosquito net production. Background Technology

[0002] The electronic single-yarn tensile strength tester can not only test the physical properties of individual yarns, but also be used to test the breaking strength and elongation of materials such as paper, medical nonwoven fabrics, medical rubber, automotive interior parts, and artificial turf. The electronic single-yarn tensile strength tester utilizes the constant rate of elongation (CRE) principle. During the entire test, one clamp on the instrument is fixed, while the other clamp moves at a constant speed. A specific sample is taken according to requirements and stretched at a specified speed until breakage. Simultaneously, the breaking strength (N) and breaking elongation (%) are recorded.

[0003] According to a prior art disclosure, a cabinet-type electronic single yarn strength tester (publication number: CN214150189U) includes a housing, two bidirectional lead screws, two mounting plates, and two U-shaped plates. A motor is fixedly mounted on the outer wall of the housing. The lower surface of the upper mounting plate is fixedly connected to the upper surface of the upper U-shaped plate via two tension sensors. A locking mechanism is fixedly installed between the right outer wall of the upper U-shaped plate and the lower surface of the upper mounting plate. The lower U-shaped plate is fixedly mounted on the upper surface of the lower mounting plate. Clamping mechanisms are fixedly installed inside both U-shaped plates. A transmission mechanism is fixedly installed between the lower walls of the two bidirectional lead screws. This invention can measure both the breaking strength and elongation of yarn, reducing operating steps and improving efficiency.

[0004] In the aforementioned application, the transmission mechanism fixed between the lower walls of the two bidirectional lead screws cannot achieve a self-cleaning function, and cannot automatically remove yarn debris and dust generated during the testing process. A locking mechanism is fixed between the right outer wall of the upper U-shaped plate and the lower surface of the upper mounting plate, but it cannot achieve an automatic clamping function, thus hindering more convenient automated operation. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model provides a cabinet-type electronic single yarn strength machine for mosquito net production, which solves the technical problems of the inability to automatically clamp and self-clean in the prior art.

[0006] According to one aspect, at least one embodiment of the present invention provides a cabinet-type electronic single yarn strength machine for mosquito net production, including a box body, a support leg fixedly connected to the bottom of the box body, a panel control device provided on the side of the box body, and a telescopic device provided inside the box body.

[0007] The telescopic device includes a motor, the side of which is fixedly connected to the side of the housing. The output shaft of the motor is fixedly connected to a rotating shaft. One end of the rotating shaft is fixedly connected to a threaded rod. An internal threaded sleeve is threaded onto the circumferential surface of the threaded rod. The circumferential surface of the internal threaded sleeve is fixedly connected to the telescopic body. A fixing plate is fixedly connected to the side of the housing. A rack is slidably connected to the top of the fixing plate. A clamping plate is fixedly connected to the top of the rack. A connecting shaft passes through the top of the fixing plate. A small gear is fixedly connected to the circumferential surface of the connecting shaft. The rotating shaft… A transmission gear one is fixedly connected to the circumferential surface of the housing. A transmission shaft two is rotatably connected to the side of the housing, and another transmission gear two is fixedly connected to the circumferential surface of the transmission shaft two. A third transmission shaft three is rotatably connected to the side of the housing, and another transmission gear three is fixedly connected to the circumferential surface of the transmission shaft three. A bevel gear one is fixedly connected to one end of the transmission shaft three. A transmission housing is fixedly connected to the top of the fixed plate. An adapter adjustment shaft is rotatably connected to the inner side of the transmission housing. A bevel gear two is fixedly connected to one end of the adapter adjustment shaft, and a pinion two is fixedly connected to the other end of the adapter adjustment shaft. Based on the above design, precise positioning and fixation can be achieved through the coordinated action of extension and clamping. The threaded drive has a self-locking characteristic, which can maintain the current position when the motor stops, preventing accidental loosening and providing overload protection.

[0008] For example, in at least one embodiment of this utility model, a cabinet-type electronic single yarn strength machine for mosquito net production further includes: the telescopic device includes a motor, the side of the motor is fixedly connected to the side of the housing, the output shaft of the motor is fixedly connected to a rotating shaft, one end of the rotating shaft is fixedly connected to a threaded rod, the circumferential surface of the threaded rod is threadedly connected to an internal threaded sleeve, the circumferential surface of the internal threaded sleeve is fixedly connected to the telescopic machine body, the side of the housing is fixedly connected to a fixing plate, the top of the fixing plate is slidably connected to a rack rod, the top of the rack rod is fixedly connected to a clamping plate, and the top of the fixing plate is through a connecting shaft. A small gear is fixedly connected to the circumferential surface of the shaft, and a transmission gear is fixedly connected to the circumferential surface of the rotating shaft. A transmission shaft is rotatably connected to the side of the housing, and a transmission gear is fixedly connected to the circumferential surface of the second transmission shaft. A third transmission shaft is rotatably connected to the side of the housing, and a transmission gear is fixedly connected to the circumferential surface of the third transmission shaft. A bevel gear is fixedly connected to one end of the third transmission shaft. A transmission housing is fixedly connected to the top of the fixed plate. An adapter adjustment shaft is rotatably connected to the inner side of the transmission housing. A bevel gear is fixedly connected to one end of the adapter adjustment shaft, and a small gear is fixedly connected to the other end. Based on the above design, the self-locking characteristics of the threaded rod and the internal threaded sleeve provide mechanical safety. When the yarn breaks, the current position is automatically locked to prevent impact damage to the sensor.

[0009] The sides of the rack and pinion mesh with the sides of pinion one and pinion two, respectively. The side of transmission gear one meshes with the side of transmission gear two, the side of transmission gear two meshes with the side of transmission gear three, and the side of bevel gear one meshes with the side of bevel gear two. Based on this design, the transmission ratio between the meshing gears is precisely controlled, effectively clamping the yarn.

[0010] A limit plate is fixedly connected to the bottom of the telescopic machine body, and one end of the limit plate is slidably connected to the side of the housing. This design prevents damage from overtravel.

[0011] The size ratio of transmission gear one, transmission gear two, and transmission gear three is set to 1:2:4. Based on the above design, the 1:2:4 size ratio of the transmission gears forms a three-stage reduction, and the output torque is amplified step by step, achieving high clamping force with low-power motor 41, which meets the high-precision loading requirements of yarn strength testing.

[0012] The inner surface of the transmission housing lies on the displacement trajectory of the clamping plate. This design provides stability and limiting of movement.

Based on the above design, the linkage design of the pulley three and the bevel gear two cleverly utilizes the power output of the original clamping mechanism, simplifying the transmission chain.

[0014] For example, in at least one embodiment of this utility model, a cabinet-type electronic single yarn strength tester for mosquito net production further includes: a scraper fixedly connected to the side of the cleaning body near the second belt. Based on the above design, the cleaning mechanism is synchronously driven by the threaded rod of the testing mechanism's power source, and the scraper's reciprocating motion is achieved through belt pulley transmission, automatically removing yarn debris and dust generated during the testing process.

[0015] There are four support legs, arranged in pairs and symmetrically along the vertical central axis of the housing. A base plate is fixedly connected to the bottom of the housing. Based on this design, the four symmetrically distributed support legs and the base plate form a stable support system, ensuring the stability of the equipment during testing.

[0016] A cylindrical support plate is fixedly connected to the top of the housing, and one end of the cylindrical support plate is fixedly connected to the side of the motor. This design improves the stability of the motor during operation.

[0017] A rotating shaft is fixedly connected to the side of the enclosure, and a security door is rotatably connected to the side of the rotating shaft. A door handle is fixedly connected to the side of the security door. This design improves security and the ease of component replacement.

The gear and rack transmission chain is reasonably laid out, which significantly reduces the space occupation and is suitable for cabinet-type equipment integration.

[0020] 2. In this utility model, the screw is rotatably connected to the sweeper body on the side near the belt box, and the scraper on the sweeper body is detachable for easy replacement of worn parts. The sweeping device, support structure, motor system, and protective door are independently designed and can be replaced and repaired individually, greatly shortening maintenance time. The cylindrical support plate on top of the housing connects the top of the housing to the side of the motor, providing rigid support for the high-torque motor. Attached Figure Description
