Description

Technical Field

[0001] The present invention relates to the technical field of cloth tension detection equipment, and in particular to a cloth tension detection equipment for knitted sweaters. Background Art

[0002] With the rapid development of the textile industry, the types and styles of knitted sweater fabrics are becoming increasingly diverse. To ensure the quality and comfort of knitted sweaters, fabric tension testing has become an indispensable part of the production process. However, existing fabric tension testing equipment has some limitations in practical applications, especially when dealing with the continuity testing of knitted fabrics of different materials and styles.

[0003] Currently, the common fabric tension testing equipment on the market mainly uses fixed fixtures and a single tension test method. The fixtures installed on the testing equipment are also only set in a pair of opposite positions. When inspecting multiple sweater fabrics with different weaving styles, the inspection is difficult to carry out quickly and continuously. During the inspection process, it is necessary to first remove the remaining fabric from the previous fixture, then reinstall the new test pattern fabric, adjust the vertical angle of the fabric, and then re-test the tension of the new sample. The inspection process is time-consuming and laborious, affecting the efficiency of sweater fabric tension testing. Therefore, a sweater fabric tension testing device is needed to solve the above problems. Summary of the Invention

[0006] Preferably, a gear set is provided at the center position of the front of the control panel base, and the gear set consists of two gear ends with different outer diameters and a gearbox body, and the small outer diameter gear shaft end is connected to a micro motor, and the large outer diameter gear of the gear set is meshed with the bottom end side of the base plate through teeth, and the large outer diameter gear and the small outer diameter gear inside the gear set are meshed, and both gears are rotatably installed in the gearbox body to prevent impurities from interfering with the operation of the gears.

[0007] Preferably, the clamp includes a secondary splint connected and fixed to the base plate, the side of the secondary splint is butt-jointed with a positive splint via a bolt group, the bolt group passes through the pressure plate and the positive splint through a through hole, an auxiliary support spring is sleeved on the surface of the bolt group, which is supported between the pressure plate and the secondary splint by the auxiliary support spring, and a constant distance between the secondary splint and the pressure plate can be maintained, which is convenient for placing the sweater fabric.

A protrusion is provided on the inner wall of the auxiliary splint, and the protrusion is flush with the M-shaped rack at the toothed plate end. When the pressure plate moves and cooperates with the auxiliary splint to clamp the sweater fabric, the friction during clamping can be increased to ensure the stability of the sweater fabric when clamped.

[0009] Preferably, the auxiliary clamping plate, bolt group, auxiliary support spring, positive clamping plate, pressure plate and threaded rotary shaft are combined to form a clamping member, and two clamping members are symmetrically arranged, the top of the upper clamping member is connected to a hanging plate, and the right side of the hanging plate is connected to a guide rail plate by bolts, and the hanging plate is connected to the guide rail plate. Under normal circumstances, the guide rail plate falls down autonomously under gravity, so that the right side of the bottom end of the hanging plate can support and contact the protruding end of the top side of the column plate, so that the specified distance between the two clamping members can be maintained.

[0014] The present invention has at least the following beneficial effects: 1. The guide rail, rail sleeve and chassis plate are used to drive the lateral displacement of multiple fixtures, and the gear group and micro motor are used for precise positioning. Multiple fixture groups can be pre-loaded with different samples and automatically switch to the inspection station during inspection, eliminating the need for manual disassembly and assembly steps. The position sensor automatically identifies the fixture position, achieving seamless connection of the inspection process and improving inspection efficiency by more than 50%.

[0015] 2. The fixture uses a positive plate and a secondary plate, and the M-shaped tooth plate on the inside of the pressure plate increases friction. The cylinder of the quick-connect part drives the hook to automatically engage with the suspension plate, realizing the rapid locking of the hydraulic system suspension beam and the fixture. The M-shaped tooth plate and the protrusion cooperate to enhance the stability of the fabric clamping and avoid slipping during inspection. The cylinder-controlled clamping mechanism realizes one-button docking, reducing manual adjustment time and ensuring that the fabric is always in a vertical suspension state.

[0016] 3. The hydraulic system's suspension beam applies load at a constant speed through programming control, and the tension sensor monitors data in real time. The chassis is equipped with a micro-motor to ensure displacement accuracy. The guide rail and ball bearing design reduce friction deviation. The hydraulic system applies force at a constant speed to prevent sudden damage to the fabric. Combined with the sensor, data is recorded in real time.

[0020] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0021] Reference Figure 1-8A knitted sweater fabric tension detection device includes a tension detection machine 1, which includes a control panel base 11, and a frame 12 is installed on the top of the control panel base 11, and a hydraulic system suspension beam 13 is movably installed on the inner side of the frame 12. A movable part 4 is movably installed on the surface of the control panel base 11, and the movable part 4 includes side support plates 41 fixed on the left and right sides of the control panel base 11, and two guide rails 42 are symmetrically installed on the top surfaces of the control panel base 11 and the side support plates 41, and rail sleeves 43 are slidably installed on the surface of the guide rails 42, and the top of the rail sleeves 43 is connected to a bottom frame plate 44, and a plurality of clamps 3 are provided on the top of the bottom frame plate 44, and the top of one of the clamps 3 is docked with the side of the hydraulic system suspension beam 13 through a quick connection part 2.

[0022] A gear set 45 is provided at the center of the front of the control panel base 11. The gear set 45 consists of two gear ends with different outer diameters and a gearbox body, and the small outer diameter gear shaft end is connected to a micro motor 46. The large outer diameter gear of the gear set 45 is meshed with the bottom side of the base plate 44 through teeth.

[0023] The clamp 3 includes a secondary clamping plate 31 connected and fixed to the base plate 44. The side of the secondary clamping plate 31 is connected to the main clamping plate 34 through a bolt group 32. The bolt group 32 passes through the pressure plate 35 and the main clamping plate 34 through a through hole. An auxiliary support spring 33 is sleeved on the surface of the bolt group 32.

[0024] The inner wall of the pressing plate 35 is butted with a toothed plate end by screws, and a threaded shaft 36 is rotatably mounted at the center of the back of the pressing plate 35 , and the shaft end of the threaded shaft 36 passes through the interior of the positive clamping plate 34 through a threaded hole.

[0025] The auxiliary clamping plate 31, the bolt group 32, the auxiliary support spring 33, the main clamping plate 34, the pressure plate 35 and the threaded shaft 36 are combined to form a clamping member, and two clamping members are symmetrically arranged. The top of the upper clamping member is connected to a hanging plate 39, and the right side of the hanging plate 39 is connected to a guide rail plate 38 through bolts.

[0026] The guide rail plate 38 is inserted into the column plate 37 through a slot, and the bottom end of the column plate 37 is connected and fixed to the base plate 44. A protrusion is provided on the inner wall side of the column plate 37, and the surface of the protrusion and the guide rail plate 38 are both smooth.

[0027] A plurality of ball ends are rotatably mounted on the inner wall side of the column plate 37 through the ball groove, and the ball ends abut against the inner wall of the guide groove on the side of the guide rail plate 38 .

[0028] The quick-connect part 2 includes a side connecting plate 21 fixed to the side of the hydraulic system suspension beam 13, the bottom end of the side connecting plate 21 is connected to the suspension shaft 22, and a position sensor 23 is installed at the center position of the bottom end of the suspension shaft 22 through a groove, and hooks 24 are movably installed on the left and right sides of the suspension shaft 22, and the inner side of the hook 24 is connected and fixed to the suspension shaft 22 through a support spring 25, and the hook 24 is fixed to the suspension plate 39 through a slot.

[0029] Two cylinders 27 are installed on the left and right sides of the side connecting plate 21 , and the ends of the piston rods of the cylinders 27 are connected and fixed to the restraining sleeve 26 , which is sleeved on the surface of the hanging shaft 22 .

[0030] The length of the control panel base 11 can be extended by the side support plate 41, and the side support plate 41 cooperates with the control panel base 11 to realize the installation of the guide rail 42. The rail sleeve 43 is guided by the guide rail 42 to ensure the stability of the movement of the bottom frame plate 44 on the surface of the control panel base 11. The movement of the bottom frame plate 44 can facilitate the movement of the clamp 3 to achieve continuous detection of knitted sweater fabrics clamped by different clamps 3. The bottom frame plate 44 and the gear set 45 cooperate through the teeth to ensure accuracy during movement. At the same time, an encoder is arranged on the surface of the micro motor 46 to ensure the rotation accuracy of the shaft end and ensure rapid start and stop during rotation.

[0031] The large outer diameter gear and the small outer diameter gear inside the gear set 45 are meshed, and both gears are rotatably installed in the gearbox body to prevent impurities from interfering with the operation of the gears. The rotation of the large outer diameter gear can control the movement of the base plate 44 through the teeth, so that the different clamps 3 positions at the top of the base plate 44 can adapt to the quick-connect part 2, thereby realizing continuous tension detection of the sweater fabric fixed on the clamp 3. The axial end of the bolt group 32 passes through the pressure plate 35 and the positive clamping plate 34 and is fixed by a nut. It is supported between the pressure plate 35 and the auxiliary clamping plate 31 by the auxiliary support spring 33, and can maintain a constant distance between the auxiliary clamping plate 31 and the pressure plate 35, which is convenient for placing the sweater fabric and enables the sweater fabric to be stably fixed between the pressure plate 35 and the auxiliary clamping plate 31.

[0032] An M-shaped rack is provided at the tooth plate end of the pressing plate 35, and a spacing is provided between the M-shaped racks. A protrusion is provided on the inner wall of the auxiliary splint 31, and the protrusion is flush with the M-shaped rack spacing at the tooth plate end. When the pressing plate 35 moves and cooperates with the auxiliary splint 31 to clamp the knitted sweater fabric, the friction force during clamping can be increased to ensure the stability of the knitted sweater fabric during clamping. The end of the threaded shaft 36 rotates and moves in the threaded hole of the main splint 34 to push the pressing plate 35, and the pressing plate 35 moves and cooperates with the auxiliary splint 31 to achieve the desired effect. The clamping of the sweater fabric ensures the stability of the sweater fabric when it is fixed. The upper and lower clamping parts cooperate to conveniently clamp the two ends of the sweater fabric, so that the sweater fabric can be vertically in a preliminary suspended state, and is docked with the guide rail plate 38 through the suspension plate 39. Under normal circumstances, the guide rail plate 38 falls down autonomously under gravity, so that the right side of the bottom end of the suspension plate 39 can support and contact the protruding end of the top side of the column plate 37, so that the specified distance between the two clamping parts can be maintained, which makes it convenient to keep the clamping distance between multiple samples uniform.

[0033] The guide rail plate 38 is guided by the column plate 37 to ensure the stability of the guide rail plate 38 during the up and down movement, prevent the guide rail plate 38 from offsetting during the up and down movement, and avoid the suspension plate 39 from tilting and offsetting, which affects the docking state of the suspension plate 39 and the suspension shaft 22. The protrusions on the inner wall of the column plate 37 and the guide rail plate 38 are both smooth, which can reduce the frictional movement resistance. At the same time, lubricating oil and other media can be added to the guide rail plate 38 and the column plate 37 to further improve the smoothness of the guide rail plate 38 when moving upward. When the guide rail plate 38 telescopes and moves inside the slot of the column plate 37, the guide rail plate 38 can rub against the ball end of the column plate 37 during movement to ensure the smoothness of the guide rail plate 38 during movement.

[0034] The side connecting plate 21 is fixed to the side of the hydraulic system suspension beam 13. The position sensor 23 at the bottom end of the suspension shaft 22 is designed to facilitate the positioning of the clamp 3 below. When one of the clamps 3 is located directly below the suspension shaft 22, the starting program of the cylinder 27 is triggered, so that the hook 24 is conveniently engaged with the slot end of the suspension plate 39, ensuring the convenience of docking the suspension shaft 22 with different suspension plates 39. The position of the restraint sleeve 26 can be controlled by the extension and contraction of the piston rod end of the cylinder 27, thereby controlling the squeezing position of the restraint sleeve 26 on the hook 24, ensuring the engaged state of the hook 24 and the suspension plate 39, and realizing the rapid assembly and docking of the suspension plate 39 and the suspension shaft 22. The restraint sleeve 26 can be limited by the suspension shaft 22 so that the restraint sleeve 26 can move up and down stably.

[0035] Working principle: According to the attached Figure 5 With attached Figure 6The cam 35 is engaged with the cam 36 and the cam 37, and the cam 37 is engaged with the cam 37. The cam 37 is engaged with the cam 37 and the cam 37. The cam 37 is engaged with the cam 37 and the cam 37. Secondly, according to the attached Figure 2 As shown, a hydraulic rod is installed inside the frame 12, and the hydraulic system suspension beam 13 is supported by the hydraulic rod. The hydraulic rod is connected to the hydraulic pump through a high-pressure hose to ensure that the connection is tight and there is no leakage. The extension and contraction of the hydraulic rod can be controlled by the hydraulic pump to apply tension. The hydraulic pump is started to gradually increase the pressure of the hydraulic oil to extend the hydraulic rod and apply tension. In the process of applying tension, a uniform speed should be maintained to avoid sudden increase or decrease in pressure to avoid damaging the fabric. While applying tension, a tension sensor or a dynamometer is used to monitor the tension of the fabric and record the tension values ​​under different tensions in order to analyze the mechanical properties of the fabric. After the test is completed, the release valve of the hydraulic pump is opened to allow the hydraulic oil to flow back to the oil tank, and the tension is gradually released to ensure that the piston rod of the hydraulic cylinder is completely reset for the next test. Finally, according to the attached Figure 4 , Attachment Figure 5 With attached Figure 8As shown, under the programming procedure, the pistons of the two cylinders 27 retract, so that the pistons of the cylinders 27 drive the restraining sleeve 26 to move, and control the restraining sleeve 26 to move up on the surface of the hanging shaft 22. At this time, the elastic force of the support spring 25 can push the hook 24, so that the hook 24 rotates and disengages from the grooves on both sides of the top of the hanging plate 39. The appropriate running program is selected through the control buttons of the control panel base 11, and the micro motor 46 is started. The shaft end rotation of the micro motor 46 controls the rotation of the two gears in the gear set 45. The gears can drive the base plate 44 to move, so that the base plate 44 drives the rail sleeve 43 to move on the surface of the guide rail 42. The position of the clamp 3 can be changed during the movement of the base plate 44, so that the new clamp 3 moves to the bottom of the hanging shaft 22. Under the induction of the position sensor 23, when the new hanging plate 39 moves to the bottom of the hanging shaft 22, it is detected by the position sensor 23. During induction, the micro motor 46 stops running. At this time, the cylinder 27 starts, and the solenoid valve is energized through the PLC control. The switching of the solenoid valve controls the extension and contraction of the cylinder 27. During operation, the compressed air enters the cylinder 27 and pushes the piston to move, thereby generating mechanical movement, causing the piston rod of the cylinder 27 to extend and move. The piston rod of the cylinder 27 presses down the restraining sleeve 26, so that the restraining sleeve 26 can move on the surface of the hanging shaft 22. As the restraining sleeve 26 moves downward, the hook 24 can be pressed down. The inclined surface of the hook 24 is pressed and rotated, which can compress the support spring 25. The bottom end of the hook 24 is controlled to be buckled in the grooves on both sides of the top of the hanging plate 39, completing the preliminary docking of the hanging shaft 22 and the hanging plate 39. Repeating the above operation can complete the tension detection. Similarly, the continuity detection of the knitted sweater fabric on different clamps 3 can be realized.
