Abstract

The utility model relates to the technical field of rubber strip detection, and discloses a rubber strip stretcher which comprises a box body, an electric telescopic rod, a first supporting plate, a tension sensor, a second supporting plate, a thumb cylinder and a box door. During use, after the box door is opened, the two thumb cylinders are controlled to work, the rubber strip can be placed in the box body, and the two ends of the rubber strip are clamped and fixed. After the box door is closed, the electric telescopic rod is controlled to work, and the first supporting plate can be driven to move in the height direction of the box body. Furthermore, the distance between the two thumb cylinders is changed, so that the rubber strip is stretched. In the stretching process, the tension sensor can detect the tension borne by the rubber strip in real time so as to map the stretching performance of the rubber strip. In addition, after the rectangular hole is closed, a closed space can be formed. Therefore, when the rubber strip exceeds the deformation limit of the rubber strip and is broken, the broken part of the rubber strip can be blocked in the box body, so that experimenters or surrounding articles are prevented from being damaged.

[0035] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0036] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0037] Combine Figures 1 to 5As shown, an embodiment of the present disclosure provides a rubber strip stretching machine, comprising a housing 1, an electric telescopic rod 2, a first support plate 3, a tension sensor 4, a second support plate 5, a thumb cylinder 6, and a housing door 7. The housing 1 includes a rectangular hole on its side wall for placing or removing the rubber strip. The electric telescopic rod 2 is mounted on the top wall of the housing 1 along the height direction of the housing 1, with the movable end of the electric telescopic rod 2 facing the bottom wall of the housing 1, and is used to provide driving force to achieve linear movement. The first support plate 3 is mounted on the movable end of the electric telescopic rod 2 and moves along the height direction of the housing 1 under the drive of the electric telescopic rod 2. The tension sensor 4 is mounted on the bottom wall of the housing 1 along the height direction of the housing 1 and is located inside the housing 1 for detecting the tension applied to the rubber strip. The second support plate 5 is mounted on top of the tension sensor 4. The plane on which the second support plate 5 is located is parallel to the plane on which the first support plate 3 is located. The second support plate 5 and the first support plate 3 are respectively used to support and mount the thumb cylinder 6. The thumb cylinders 6 are respectively mounted on the opposite sides of the second support plate 5 and the first support plate 3. The two thumb cylinders 6 are respectively used to clamp the two ends of the rubber strip to fix the rubber strip. The box door 7 is movably mounted on the box body 1 to open or close the rectangular hole.

[0038] The embodiment of the present disclosure provides a rubber strip stretching machine. After opening the box door 7, the two thumb cylinders 6 are controlled to work, so that the rubber strip can be placed inside the box body 1 and the two ends of the rubber strip can be clamped and fixed. After closing the box door 7, the electric telescopic rod 2 is controlled to work, so that the first support plate 3 can be driven to move along the height direction of the box body 1. The spacing between the two thumb cylinders 6 is then changed, thereby stretching the rubber strip. During the stretching process, the tension sensor 4 will detect the tension applied to the rubber strip in real time to map the tensile properties of the rubber strip. In addition, after the rectangular hole is closed, an enclosed space can be formed. Therefore, when the rubber strip exceeds its own deformation limit and breaks, the broken part of the rubber strip will be blocked inside the box body 1. This avoids damage to the experimenter or surrounding objects and solves the impact of the broken part of the rubber strip being illuminated by flying.

[0039] Optionally, combined Figure 1 、 Figure 3 and Figure 4 As shown, the box body 1 further includes a first guide rail 8, a first slider 9, and a first connecting plate 10.

[0040] In the embodiment of the present disclosure, under the guiding support of the first guide rail 8 and the first slider 9, the stability of the first support plate 3 when moving along the height direction of the box body 1 can be improved, and the radial force on the moving end of the electric telescopic rod 2 can be reduced.

[0041] Optionally, combined Figure 1 and Figure 3 As shown, the second slide block 11 and the second connecting plate 12 are also included. The second slide block 11 is slidably mounted on the first guide rail 8, and the two together serve as a guide and support. The second connecting plate 12 is mounted on the second slide block 11 and connected to the second support plate 5, which is used to synchronize the movement of the second support plate 5 and the second slide block 11.

[0042] In the embodiment of the present disclosure, under the guiding support of the second guide rail 15 and the second slider 11, the stability of the second support plate 5 when slightly moving along the height direction of the box body 1 can be improved, and the tension sensor 4 can only be stretched.

[0044] The disclosed embodiment also includes clamping blocks 13 mounted on the two movable ends of each thumb cylinder 6. During use, controlling either thumb cylinder 6 drives the two clamping blocks 13 connected to it toward or away from each other, thereby tightening or loosening the ends of the rubber strip. The design of the clamping blocks 13 increases the contact area with the rubber strip, thereby improving the grip and retention of the rubber strip.

[0045] Optionally, combined Figures 1 to 3 As shown, the system further includes pads 14, second guide rails 15, and third sliders 16.

Third sliders 16 are slidably mounted on the second guide rails 15 on either side of each thumb cylinder 6. The third sliders 16 on either side of each thumb cylinder 6 are connected to the two moving ends of the adjacent thumb cylinder 6, respectively, to provide guidance and support.

[0046] In the embodiment of the present disclosure, multiple guide rails and multiple sliders are used to serve as guide supports to improve the stability of the moving ends of the two thumb cylinders 6 during movement and reduce the force exerted on the moving ends of the two thumb cylinders 6.

[0047] Optionally, combined Figure 3 and Figure 5 As shown, a butterfly hinge 17 is further included. One side of the butterfly hinge 17 is installed on the box door 7, and the other side of the butterfly hinge 17 is installed on the outer wall of the box body 1.

The second support is rotatably connected to the other end of the hydraulic telescopic rod 18 and mounted to the inner wall of the box body 1, allowing the hydraulic telescopic rod 18 to rotate relative to the box body 1.

[0050] In the embodiment of the present disclosure, the hydraulic telescopic rod 18 is used to play the role of elastic support, which can keep the box door 7 at a specific position after opening, and can also make the box door 7 tightly fastened to the box body 1 after closing.
