Technical Field
[0001] This utility model belongs to the technical field of tensile strength testing devices, and in particular relates to a tensile strength testing device for conveyor belt processing. Background Technology
[0002] Tensile strength testing devices are instruments used to test the mechanical properties of materials. They are mainly used to measure the strength and toughness of materials under tensile force. Common applications include metal products, plastics, rubber, and textiles. When processing conveyor belts, tensile strength testing devices are also needed to test the tensile strength of the conveyor belt. During testing, both ends of the conveyor belt need to be fixed in advance to facilitate subsequent pulling. However, traditional tensile strength testing devices for conveyor belt processing have poor positioning effects and cannot perform multi-directional and multi-form positioning of both ends of the conveyor belt. This causes the conveyor belt to easily detach during the pulling process, which directly affects the accuracy of the tensile performance test of the conveyor belt. Utility Model Content

By incorporating anti-detachment components, the two ends of the conveyor belt body can be bent, and the sides of the bent ends can be initially pressed and positioned. Simultaneously, the top near the bent end can be pressed and positioned. Multiple sets of pointed cones can be used to further insert and position the bent ends of the conveyor belt body. This multi-group, multi-directional, and multi-form positioning method quickly fixes both ends of the conveyor belt body within the moving frame, improving the positioning effect of the conveyor belt body and effectively preventing it from easily detaching during pulling. This improves the accuracy of testing the tensile strength of the conveyor belt body, thus solving the aforementioned technical problems.

[0023] Example 1: A tensile strength testing device for conveyor belt processing includes a positioning plate 1 and a conveyor belt body 11. A movable frame 2 is fixedly and slidably mounted on the left and right sides of the top of the positioning plate 1, respectively. A controller is mounted on the right side of the top of the positioning plate 1. A cylinder 3 is fixed to the right side of the top of the positioning plate 1 via a support plate.

A pulling frame 5 is inserted into the reinforcing side frame 4, and the piston rod of the cylinder 3 is fixed to the pulling frame 5. Multiple pressure sensors 6 are embedded in the left square plate of the pulling frame 5, which cooperate with the reinforcing side frame 4. Both ends of the conveyor belt body 11 are located within the movable frame 2 and are in contact with the inner side of the inner cavity of the movable frame 2. An anti-detachment component is installed within the movable frame 2, which cooperates with the conveyor belt body 11. The anti-detachment component includes components slidably mounted within the movable frame 2 and in contact with the bent ends of the conveyor belt body 11. The top of the moving frame 2, which is far apart from each other, is fitted with a first electric push rod 9 with a piston rod fixed to the clamping plate 10.

Side frames 13 are fixed to the inner sides of the front and back of the moving frame 2. A second electric push rod 14 with a piston rod fixed to the bottom of the compression frame 12 is embedded in the bottom of the side frame 13. A placement groove 18 is opened on the top of the moving frame 2 that is close to each other. A pressure plate 19 is snapped into the placement groove 18. Multiple sets of pointed cones 20 with one end inserted into the bent end of the conveyor belt body 11 are fixed in sequence along the front and back direction on the top and bottom of the side of the pressure plate 19 that is far apart from each other. Springs 21 are symmetrically fixed on the front and back of the side of the pressure plate 19 that is close to each other. A U-shaped frame 17 fixed to the moving frame 2 is fixed to one end of the spring 21.
[0024] Specifically, this utility model, by setting an anti-detachment component, can bend both ends of the conveyor belt body 11, and with the assistance of the first electric push rod 9 and the clamping plate 10, initially press and position the side of the bent end of the conveyor belt body 11. The design of the extrusion frame 12 and the second electric push rod 14 can simultaneously press and position the top near the bent end. At the same time, the spring 21 continuously provides a pushing force to the pressure plate 19, causing multiple sets of pointed cones 20 to be quickly inserted into the bent end of the conveyor belt body 11, and assisting in multi-point pulling of the bent end of the conveyor belt body 11. At this time, by using multiple sets, multiple directions and multiple forms of positioning methods, both ends of the conveyor belt body 11 can be quickly fixed in the moving frame 2, improving the positioning effect of the conveyor belt body 11, effectively preventing the conveyor belt body 11 from easily detaching during the pulling process, and improving the detection accuracy of the tensile performance of the conveyor belt body 11.
[0025] Each set of clamping plates 10 has a pre-set groove on its front and back sides to engage with a limiting slide plate 15. The side of the limiting slide plate 15 that is far apart from each other is fixed to the front and back sides of the inner cavity of the movable frame 2.
[0026] Specifically, the design of the limiting slide plate 15, by engaging with the preset groove, can limit the position of the clamp plate 10, improve the stability of the clamp plate 10 when it moves, and prevent it from falling or tilting.
[0027] Auxiliary pullers 22 are inserted on the side of the U-shaped frame 17 that is close to each other, and the side of the auxiliary pullers 22 that is far away from each other is fixed on the pressure plate 19. There are at least two sets of springs 21 on each pressure plate 19.
[0028] Specifically, the design of the auxiliary pull frame 22 facilitates the change of the position of the pressure plate 19, thereby assisting the conveyor belt body 11 to quickly detach from the moving frame 2.
[0029] Both the front and back of the extrusion frame 12 are secured with auxiliary plates 16 via pre-set locking channels. The opposite sides of the auxiliary plates 16 are fixed to the bottom of the front and back of the inner cavity of the extrusion frame 12.
[0030] Specifically, the design of the auxiliary retaining plate 16, by engaging with the preset guideway, can limit the movement direction of the extrusion frame 12, prevent the extrusion frame 12 from tilting during movement, and improve the pressing stability of the extrusion frame 12 on the conveyor belt body 11.
[0031] The top of the positioning plate 1 is symmetrically provided with anti-slip grooves 8, and the bottom of the right movable frame 2 is symmetrically fixed with anti-slip sliding plates 7 that slide in cooperation with the anti-slip grooves 8.
[0032] Specifically, by utilizing the sliding cooperation of the anti-slip groove 8 and the anti-slip plate 7, the moving direction and moving distance of the right moving frame 2 can be limited, so as to limit the sliding of the right moving frame 2.
[0033] Each set of anti-slip plate 7 has triangular reinforcement supports fixed to the bottom of both sides of the movable frame 2 on the inside, on both sides of the top.
[0034] Specifically, the design of the triangular reinforcement support can provide auxiliary reinforcement to the right-side movable frame 2, thereby improving the overall stability of the right-side movable frame 2.
[0035] The number of pressure sensors 6 on the left side square plate of the pull frame 5 is at least two sets, and the two sets of pressure sensors 6 are set diagonally opposite each other.
[0036] Specifically, the number and location of pressure sensors 6 are limited so that the pressure values of the pull frame 5 can be measured from multiple points, thereby facilitating accurate testing of the tensile properties of the conveyor belt body 11 and avoiding errors.
[0037] The specific usage process is as follows: The user first bends one end of the conveyor belt body 11 and inserts it into the moving frame 2 from above. At this time, the user activates the first electric push rod 9 through the controller, which drives the clamping plate 10 to move inward until the clamping plate 10 contacts the conveyor belt body 11. Under the limiting cooperation of the inner wall of the moving frame 2, the bent end of the conveyor belt body 11 is initially limited. At the same time, using the elastic rebound of the spring 21, while the clamping plate 10 pushes and positions the bent end of the conveyor belt body 11, multiple sets of pointed cones 20 are simultaneously inserted into the bent end of the conveyor belt body 11 to assist in positioning the bent end of the conveyor belt body 11. Then, the user fixes the other end of the conveyor belt body 11 into another set of moving frames 2 in the above manner, and then... The controller activates cylinder 3, which in turn moves the right-side moving frame 2 a certain distance to the right, bringing the conveyor belt body 11 to a suitable tension. The user then activates the second electric push rod 14 via the controller, causing the compression frame 12 to move downwards and compress and position the top side of the conveyor belt body 11. Using multiple sets of multi-directional and multi-form positioning methods, both ends of the conveyor belt body 11 can be quickly fixed within the moving frame 2. At this time, pressure sensor 6 records the pressure value of the pulling frame 5. Subsequently, the user controls the right-side moving frame 2 to continue moving via cylinder 3, rapidly pulling the conveyor belt body 11 until it breaks. Pressure sensor 6 records the pressure value at the moment of breakage and transmits the signal to the controller. This allows for rapid testing of the tensile strength of the conveyor belt body 11. By incorporating an anti-detachment component, the two ends of the conveyor belt body 11 can be bent. With the assistance of the first electric push rod 9 and the clamping plate 10, the sides of the bent ends of the conveyor belt body 11 are initially pressed and positioned. Furthermore, the design of the extrusion frame 12 and the second electric push rod 14 allows for simultaneous pressing and positioning of the top near the bent end. Simultaneously, the spring 21 continuously provides a pushing force to the pressure plate 19, causing multiple sets of pointed cones 20 to be quickly inserted into the bent ends of the conveyor belt body 11, providing auxiliary multi-point pulling on the bent ends. At this point, using multiple sets, multiple directions, and multiple forms of positioning methods, both ends of the conveyor belt body 11 can be quickly fixed within the moving frame 2. The design improves the positioning effect of the conveyor belt body 11, effectively preventing the conveyor belt body 11 from easily detaching during the pulling process, and improves the detection accuracy of the tensile performance of the conveyor belt body 11; the design of the limiting slide plate 15, which engages with the preset groove, can limit the position of the clamping plate 10, improve the stability of the clamping plate 10 when moving, and prevent it from falling or tilting; the design of the auxiliary pull frame 22 makes it easy to change the position of the pressure plate 19, thereby assisting the conveyor belt body 11 to quickly detach from the moving frame 2; the design of the auxiliary fixing plate 16, which engages with the preset locking channel, can limit the moving direction of the pressing frame 12, prevent the pressing frame 12 from tilting when moving, and improve the pressing stability of the pressing frame 12 on the conveyor belt body 11;By utilizing the sliding cooperation of the anti-slip groove 8 and the anti-slip plate 7, the movement direction and distance of the right-side moving frame 2 can be limited, thus limiting its sliding movement. The design of the triangular reinforcing support provides auxiliary reinforcement to the right-side moving frame 2, improving its overall stability. Limiting the number and location of pressure sensors 6 allows for measuring the pressure values of the pulling frame 5 from multiple points, facilitating accurate testing of the tensile strength of the conveyor belt body 11 and avoiding errors.
[0038] In summary, this tensile strength testing device for conveyor belt processing, by setting up anti-detachment components and utilizing multiple sets, multiple directions and multiple forms of positioning methods, can quickly fix both ends of the conveyor belt body within the moving frame, improving the positioning effect of the conveyor belt body, effectively preventing the conveyor belt body from easily detaching during the pulling process, and improving the testing accuracy of the tensile strength of the conveyor belt body.
