Description

Technical Field

[0001] This utility model relates to the field of silicone production technology, and in particular to a silicone tube stretching device. Background Technology

[0002] Silicone tubing serves as a carrier for the flow and encapsulation of liquids, gases, and other materials. In the industry, silicone rubber tubing can be categorized into extruded tubing and shaped tubing strips, and is widely used in modern industry, defense industry, and daily necessities. Silicone tubing is produced by adding raw silicone rubber to a two-roll mill or a closed kneader, gradually adding silica and other additives, and repeatedly refining until uniform. Following industry product technical standards, the product is then extruded. Conductive silicone rubber can be used in the electronics industry. During the production of silicone tubing, a stretching device is required to test its performance.

[0003] According to a search, Chinese patent document CN219715053U discloses a silicone tube tensile testing device. By starting a motor, a gear inside a groove rotates. The gear, through its toothed groove, causes a rotating shaft to rotate counter-clockwise on a support plate. As the shaft rotates, a rope gradually winds around its surface via a slot. The rope, through a tension sensor, applies tension to a pull plate, causing the pull plate to move one end of the silicone tube towards a second position on the side plate. At this point, the silicone tube gradually stretches. The tension sensor detects the magnitude of the tension applied by the rope to the pull plate, thus detecting the tensile force borne by the silicone tube during stretching. This method is relatively convenient. However, the clamping mechanism of this silicone tube tensile testing device has low flexibility, only adapting to one size of silicone tube and unable to fix silicone tubes of different sizes, reducing the device's adaptability.

[0004] Therefore, existing silicone tube tensile testing devices have low clamping mechanism flexibility, only adapting to one size of silicone tube and unable to fix silicone tubes of different sizes, reducing the device's adaptability. A silicone tube tensile device can be designed by setting up a knob one, a mounting bracket, a knob two, an arc-shaped pressing plate, and a support column. The mounting screw holes and studs facilitate the replacement of different support columns. Rotating knob one moves the arc-shaped pressing plate downwards, and rotating knob two moves the arc-shaped pressing plates on both sides inwards. The arc-shaped pressing plates, in conjunction with the support column, fix the silicone tube, allowing the device to adapt to silicone tubes of different sizes and improving its applicability. Utility Model Content

[0005] To overcome the problem that the existing silicone tube tensile testing device has low clamping mechanism flexibility, can only adapt to one size of silicone tube and cannot fix silicone tubes of different sizes, thus reducing the adaptability of the device.

The mounting frame is connected to the front of the movable block. A knob is provided on the left side of the mounting frame. A bidirectional screw is connected to the right side of the knob. The right end of the bidirectional screw is mounted inside the right side of the mounting frame via a bearing. Movable blocks are threadedly connected to the outer sides of both ends of the bidirectional screw. An arc-shaped pressing plate is connected to the bottom of the movable block. Installation screw holes are provided on the inner side of each side plate. A stud is threadedly connected to the inner side of each installation screw hole. A support column is connected to the inner side of the stud.

[0007] Preferably, the inner front and rear ends of the side plate are provided with T-shaped grooves, and T-shaped blocks are provided inside the T-shaped grooves. The T-shaped blocks are connected to the outside of the mounting bracket.

[0008] Preferably, the top of the base plate has a second mounting groove, and the right side of the base plate has a motor installed.

[0009] Preferably, the output end of the motor is connected to a threaded rod two, and the other end of the threaded rod two is mounted on the left side inside the mounting groove two via a bearing.

[0010] Preferably, the outer side of the threaded rod two is threadedly connected to a movable block three, and the top of the movable block three is connected to a support plate.

[0011] Preferably, the bottom of the left side plate is connected to the top left side of the base plate, and the bottom of the right side plate is connected to the top of the support plate. A T-shaped groove 2 is provided on the top right side of the support plate, and a T-shaped block 2 is provided inside the T-shaped groove 2. The top of the T-shaped block 2 is connected to the bottom of the right side plate.

[0012] Preferably, a baffle is connected to the top left side of the support plate, and electric actuators are installed at both the front and rear ends of the right side of the baffle. The output end of the electric actuator is connected to a push plate, and a pressure sensor is installed at the lower inner end of the right side plate. The height of the push plate and the pressure sensor are matched.

[0013] The beneficial effects of this utility model are:

[0014] 1. By setting up threaded rod one, movable block one, knob one, mounting bracket, double screw, knob two, movable block two, arc-shaped pressing plate and support column, the setting of mounting screw holes and studs facilitates the replacement of different support columns. Rotating knob one can drive the arc-shaped pressing plate downward through threaded rod one, movable block one and mounting bracket. Rotating knob two can drive the arc-shaped pressing plates on both sides to move inward through double screw and movable block two. The arc-shaped pressing plates can thus cooperate with the support column to fix the silicone tube, so that the device can be adapted to silicone tubes of different sizes, thus improving the applicability of the device.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figures 1-4This utility model provides an embodiment of a silicone tube stretching device, including a base plate 1; it also includes a threaded rod 4, a movable block 5, a knob 6, a mounting bracket 7, a bidirectional screw 8, a second knob 9, a second movable block 10, an arc-shaped pressing plate 11, and a support column 14. Side plates 2 are provided on both the left and right sides of the upper end of the base plate 1. A mounting groove 3 is formed on the upper inner side of the side plate 2. A knob 6 is provided on the top of the side plate 2. The bottom of the knob 6 is connected to the threaded rod 4. The other end of the threaded rod 4 is mounted on the bottom of the mounting groove 3 via a bearing. The outer side of the threaded rod 4 is threadedly connected to the movable block 5. The front of the movable block 5 is connected to the mounting bracket 7. A second knob 9 is provided on the left side of the mounting bracket 7. A bidirectional screw 8 is connected to the right side of the knob 9. The right end of the bidirectional screw 8 is mounted on the right side of the mounting bracket 7 via a bearing. The outer sides of both ends of the bidirectional screw 8 are threadedly connected to the second movable block 10. The bottom of the second movable block 10 is connected to an arc-shaped pressing plate 11. The curved pressing plate 11 has mounting screw holes 16 on the inner side of the side plate 2. A stud 15 is threaded into the mounting screw hole 16, and a support column 14 is connected to the inner side of the stud 15. Personnel can replace the support column 14 through the mounting screw hole 16 to adjust its size to match the silicone tube being tested. When fixing the silicone tube, first, the silicone tube is placed on the support column 14. Then, knob 6 is rotated, causing the threaded rod 4 to rotate. The moving block 5, acting on the thread of the threaded rod 4, moves the mounting bracket 7 downwards, which in turn moves the curved pressing plate 11 downwards. After moving the curved pressing plate 11 to the appropriate height, knob 9 is rotated, causing the bidirectional screw 8 to rotate. The moving block 10, acting on the thread of the bidirectional screw 8, moves the curved pressing plates 11 on both sides inwards, thus fixing the silicone tube to the support column 14.

[0022] Please see Figures 2-3 In this embodiment, T-slots 12 are provided at both the front and rear ends of the inner side of the side plate 2. T-blocks 13 are provided inside the T-slots 12. The T-blocks 13 are connected to the outer side of the mounting frame 7. The T-slots 12 and T-blocks 13 can limit the lifting and lowering of the mounting frame 7, thereby ensuring the stability of the lifting and lowering of the mounting frame 7.

[0023] Please see Figures 1-4In this embodiment, the top of the base plate 1 is provided with a second mounting groove 17, and a motor 20 is installed on the right side of the base plate 1. The output end of the motor 20 is connected to a second threaded rod 18, and the other end of the second threaded rod 18 is installed on the left side inside the second mounting groove 17 through a bearing. The outer side of the second threaded rod 18 is threadedly connected to a third moving block 19, and the top of the third moving block 19 is connected to a support plate 21. When the motor 20 is started, the output end of the motor 20 can drive the second threaded rod 18 to rotate. The third moving block 19 is acted upon by the thread of the second threaded rod 18, thereby driving the right side plate 2 to move left and right through the support plate 21. Personnel can then adjust the distance between the two side plates 2 to match the length of the silicone tube to be tested.

[0024] Please see Figures 1-4 In this embodiment, the bottom of the left side plate 2 is connected to the top left side of the base plate 1, and the bottom of the right side plate 2 is connected to the top of the support plate 21. A T-shaped groove 26 is provided on the top right side of the support plate 21, and a T-shaped block 27 is provided inside the T-shaped groove 26. The top of the T-shaped block 27 is connected to the bottom of the right side plate 2. A baffle 22 is connected to the top left side of the support plate 21. Electric push rods 23 are installed at both the front and rear ends of the right side of the baffle 22. The output end of the electric push rod 23 is connected to a push plate 24. A pressure sensor is installed on the lower inner side of the right side plate 2. 25. The heights of the push plate 24 and the pressure sensor 25 are matched. The model of the pressure sensor 25 is consistent with that in the comparative patent. When the electric push rod 23 is activated, the output end of the electric push rod 23 can drive the push plate 24 to move to the right. The push plate 24 can then push the right side plate 2 to move to the right through the pressure sensor 25. The right side plate 2 can then stretch the silicone tube. At this time, the pressure sensor 25 can then monitor the stretching force of the silicone tube. The T-slot 26 and T-block 27 are designed to facilitate the sliding of the side plate 2.

[0025] During operation, personnel can replace the support column 14 through the mounting screw hole 16 to adjust its size to match the silicone tube to be tested. Then, the motor 20 is started, and its output drives the threaded rod 18 to rotate. The moving block 19, acting on the thread of the threaded rod 18, moves the right side plate 2 left and right via the support plate 21. After adjusting the spacing of the support columns 14 on both side plates 2 to match the length of the silicone tube to be tested, the silicone tube can be fixed. First, the silicone tube is fitted onto the support column 14. Then, the knob 6 is turned, causing the threaded rod 4 to rotate. The moving block 5, acting on the thread of the threaded rod 4, moves the mounting bracket 7 towards... The downward movement of the curved pressing plate 11 causes it to move downward. After the curved pressing plate 11 is moved to a suitable height, the knob 9 is turned. The knob 9 drives the bidirectional screw 8 to rotate. The moving block 10 is driven by the thread of the bidirectional screw 8, which causes the curved pressing plates 11 on both sides to move inward. The curved pressing plate 11 can then fix the silicone tube to the supporting column 14. After the silicone tube is clamped and fixed at both ends, the electric push rod 23 is activated. The electric push rod 23 can drive the push plate 24 to move to the right. The push plate 24 can then push the right side plate 2 to move to the right through the pressure sensor 25. At this time, the silicone tube is stretched. The pressure sensor 25 can then monitor the stretching force of the silicone tube.

[0026] Through the above steps, the installation of knob 6, mounting bracket 7, knob 9, arc-shaped pressing plate 11, and support column 14, along with the mounting screw holes 16 and studs 15, facilitates the replacement of different support columns 14. Rotating knob 6 causes the arc-shaped pressing plate 11 to move downwards, and rotating knob 9 causes the arc-shaped pressing plates 11 on both sides to move inwards. The arc-shaped pressing plates 11 thus cooperate with the support column 14 to fix the silicone tube, enabling the device to adapt to silicone tubes of different sizes. This improves the applicability of the device and solves the problem that the existing silicone tube tensile testing device has low clamping mechanism flexibility, can only adapt to one size of silicone tube, and cannot fix silicone tubes of different sizes, thus reducing the adaptability of the device.
