Some high-end customized belts are not punched before sales, and the use of hooks will cause the hooks to damage the perforations of the belt when the belt is stretched, making it more susceptible to damage, resulting in reduced yield and increased production costs. To address this problem, the utility model solves it by installing a suction cup. When the staff needs to fix one end of the belt, the belt end is passed through the semicircular rotating cylinders, and then the motor is started to rotate the negative pressure turbine to form a negative pressure, so that the inlet pressure at the suction hole of the suction cup is lower than the atmospheric pressure, and the belt is tightly adsorbed on the suction cup. Then the turntable drives the semicircular rotating cylinder to rotate and rolls up the belt, avoiding belt damage and surface wrinkles, thereby achieving the effect of improving the yield.

The belt is often rolled up after being fixed, and the toughness and fatigue strength of the belt are tested by repeated winding, and whether there are cracks and wrinkles on the surface of the belt. When fixing the belt, the existing testing equipment generally uses a clamp or a hook to hang the belt through the perforation. When the clamp is used for fixing, the belt surface is smooth and often falls off, causing the belt to lose control and injure the staff. Increasing the clamp pressure will damage the belt and affect the performance test. Some high-end customized belts are not punched before sales, and the use of hooks will When the belt is stretched, the hooks damage the perforations of the belt, making it more susceptible to damage, resulting in reduced yield and increased production costs. To address this problem, the utility model solves the problem by installing a suction cup. When a worker needs to fix one end of the belt, the belt end is passed through between the semicircular rotating cylinders, and then the motor is started to rotate the negative pressure turbine to form a negative pressure, so that the inlet pressure at the suction hole of the suction cup is lower than the atmospheric pressure, and the belt is tightly adsorbed on the suction cup. Subsequently, the turntable drives the semicircular rotating cylinder to rotate and rolls up the belt, avoiding damage to the belt and surface wrinkles, thereby achieving the effect of improving the yield.

[0013] 2. In the prior art, the belt is prone to flipping and sliding when rolled up. The reversal will cause long creases to form on the belt surface, greatly reducing the quality of the belt. The belt sliding will cause the belt to swing continuously when rolled up, making the rolling uneven and causing inaccurate performance testing. To address such problems, the utility model solves them by installing positioning columns. Before the performance test, the staff passes the belt through the positioning columns. The friction force on the surface of the positioning columns makes the belt straight to avoid folding, and the baffle prevents the belt from swinging, thereby improving the neatness and tightness of the rolling up, thereby increasing the accuracy of the performance test.

[0014] 3. In the prior art, when the belt is rolled up, part of the belt bends downward due to its own weight, which makes the belt not tight enough when curled, and the belt surface cannot be curled evenly, causing some parts of the belt surface to be easily wrinkled and cracked, while the other part is almost not stressed.

[0021] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0022] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings. Specific embodiment:

[0024] Reference Figure 1-4 A belt performance testing device comprises a test protection box 1, the inner wall of the test protection box 1 is rotatably connected with a turntable 2, a semicircular rotating column 201 is fixed on one side of the turntable 2, a circular array of air outlet holes 202 are provided on the surface of the semicircular rotating column 201, a suction cup 203 is fixed on the bottom of the semicircular rotating column 201, a suction hole 204 is provided on the surface of the suction cup 203, a column groove 205 is provided inside the semicircular rotating column 201, a motor 206 is fixed on the inner wall of the column groove 205, a negative pressure turbine 207 is fixed on one end of the motor 206, the inner wall of the column groove 205 is connected with the inner wall of the air outlet hole 202, the belt needs to undergo a performance sampling test before use, and the belt is often rolled up after being fixed, and the toughness and fatigue strength of the belt are tested by repeated winding, and whether there are cracks and wrinkles on the surface of the belt is observed, and when fixing the belt, the existing testing equipment generally uses a clamp or hangs the belt through the perforation by a hook, When the clamp is used for fixing, the surface of the belt is smooth and often falls off, causing the belt to lose control and injure the staff. Increasing the clamp pressure will damage the belt and affect the performance test. Some high-end customized belts are not punched before sales, and the use of hooks will cause the belt to be damaged by the hooks when it is stretched, which is more likely to be damaged, resulting in a decrease in the yield rate and an increase in production costs. The problem is solved by installing a suction cup 203. When the staff needs to fix one end of the belt, one end of the belt is passed through the semicircular rotating cylinder 201, and then the motor 206 is started to rotate the negative pressure turbine 207 to form a negative pressure, so that the inlet pressure at the suction hole 204 of the suction cup 203 is lower than the atmospheric pressure, and the belt is tightly adsorbed at the suction cup 203. Then the turntable 2 drives the semicircular rotating cylinder 201 to rotate, and the belt is rolled up to avoid damage to the belt and surface wrinkles, thereby achieving the effect of improving the yield rate. A limiting side disc 208 is fixed at one end of the semicircular rotating cylinder 201 to limit the belt from entering the position and prevent the belt from curling and skewing. A glass groove 101 is provided on the inner wall of the test protection box 1, and the glass is installed to facilitate real-time observation by the staff.

[0025] The inner wall of the test protection box 1 is rotatably connected with a positioning column 3, and a stopper 301 is fixed at one end of the positioning column 3. The belt is easy to flip and slide when it is rolled up. The reversal will form a long crease on the surface of the belt, which greatly reduces the quality of the belt. The sliding of the belt will cause the belt to sway continuously when it is rolled up, making the rolling uneven and causing inaccurate performance testing. The problem is solved by installing positioning columns 3. Before the performance test, the staff passes the belt through the positioning columns 3. The friction on the surface of the positioning columns 3 makes the belt straight to avoid folding, and the stopper 301 prevents the belt from swaying, improving the neatness and tightness of the rolling, and achieving the effect of increasing the accuracy of the performance test. A limiting member 103 is fixed on one side of the test protection box 1 to prevent the belt from swaying left and right when entering the equipment and causing harm to the staff. A rubber pad 102 is fixed at the bottom of the test protection box 1. The rubber pad 102 reduces noise through a buffering effect between the equipment and the ground. The inner wall of the test protection box 1 is rotatably connected with a downward pressure column 302, and the inner wall of the test protection box 1 is rotatably connected with an upward column 303. When the belt is rolled up, part of the belt is bent downward due to its own weight, so that the belt is not tight enough when curled, and the belt surface cannot be curled evenly, causing some parts of the belt surface to be prone to wrinkles and cracks, while the other part is almost not stressed. This is solved by installing a downward pressure column 302 and an upward column 303. When the belt is heavy, the staff makes the belt surface contact with the downward pressure column 302 and the upward column 303 respectively. Through the friction force and distance between the two column surfaces, the straightness and stretching degree of the belt are improved, and the belt is prevented from bending due to small force, so that the belt surface is evenly stressed, and the tightness of the rolling is increased, thereby achieving the effect of improving the test stability.

[0026] The working principle of the utility model is as follows: when the staff needs to fix one end of the belt, the staff will pass the one end of the belt through the semicircular rotating cylinders 201, and then start the motor 206 to rotate the negative pressure turbine 207 to form a negative pressure, so that the inlet pressure at the suction hole 204 of the suction cup 203 is lower than the atmospheric pressure, and the belt is tightly adsorbed on the suction cup 203. Then the turntable 2 drives the semicircular rotating cylinder 201 to rotate and roll up the belt. Before the performance test, the staff will pass the belt through the positioning columns 3, and the friction force on the surface of the positioning columns 3 will make the belt straight to avoid folding, and the stopper 301 will prevent the belt from swinging. When the belt is heavy, the staff will make the belt surface contact with the lower pressure column 302 and the upper pick column 303 respectively, and the straightness and stretchability of the belt will be improved through the friction force and distance between the two column surfaces.
