Description

Technical Field

[0001] This utility model relates to the field of tape processing technology, specifically to a water pressure plate used in a tape vulcanizing machine. Background Technology

[0002] A belt vulcanizing machine is a specialized device for vulcanizing rubber belt joints. It is mainly used for bonding the joints of rubber belts in conveyor machinery. By providing appropriate temperature, pressure, and time, it enables the belt joint to achieve a vulcanization effect, thereby enhancing the strength and durability of the joint. Belt vulcanizing machines are widely used in metallurgy, mining, power plants, ports, building materials, chemical and other fields, and are suitable for vulcanizing various types of belt joints, such as canvas, nylon, and steel cord conveyor belts.

[0003] Operators frequently use hydraulic pressure plates to apply pressure to the conveyor belt vulcanizing machine. While existing hydraulic pressure plates offer basic pressurization capabilities, their simple structure makes width adjustment difficult. This limits their ability to fix rubber pads of a fixed size, reducing their applicability and increasing operator workload due to frequent replacements of the pressure plates. Therefore, improvements are necessary. Utility Model Content

[0007] As a preferred technical solution of this utility model, the top of both the fixed frame and the connecting frame are fixedly connected to the mounting frame. The mounting frame is threaded with a No. 1 threaded rod. The left end of the No. 1 threaded rod passes through the mounting frame and extends into the interior of the mounting frame and is movably connected to a connecting block. The left end of the connecting block is hinged to a diagonal rod, and the other end of the diagonal rod is hinged to a vertical plate.

[0008] As a preferred technical solution of this utility model, there are four vertical plates. The bottom of the four vertical plates passes through the fixing frame and the connecting frame and extends into the interior of the fixing frame and the connecting frame, and are respectively fixedly connected to a first pressure plate and a second pressure plate.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. This utility model, by setting a fixed plate, a pull rod, a locking block, a gear, and a spring, allows the spring to be compressed when the pull rod is pulled. This compression causes the locking block to move vertically downwards under the limiting action of the fixed plate, disengaging the locking block from the outer surface of the gear. This releases the gear from its fixing effect. Then, rotating the double-threaded rod causes the two connecting frames to move horizontally towards each other along the interior of the fixed frame under the limiting action of the limiting rod. This achieves the purpose of adjusting the distance between the two connecting frames and allows the device to fix rubber pads of different widths, thus improving the application range of the device.

[0017] 2. This utility model, by setting up a connecting block, a diagonal rod, a vertical plate, a first pressure plate, and a second pressure plate, allows the first threaded rod to be rotated, causing it to squeeze and push the connecting block to move horizontally to the left, and causing the diagonal rod to move. At this time, under the limiting action of the fixed frame and the connecting frame, the four vertical plates will move vertically downwards, and will respectively drive the first pressure plate and the second pressure plate to move vertically downwards. At this time, the first triangular plate and the vertical rod cooperate with the sliding groove and the circular groove, thereby achieving a sealing effect around the rubber pad. At the same time, it eliminates the need to use multiple sets of bolts and nuts for fixing, improving the efficiency of the operator in fixing the rubber pad and reducing the labor intensity of the operator.

[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0027] like Figures 1 to 6 As shown, this utility model provides a water pressure plate for a tape vulcanizing machine, including a water pressure plate body 1. Fixing frames 2 are fixedly connected to the front and rear sides of the top of the water pressure plate body 1. A double-threaded rod 3 is movably sleeved inside the fixing frame 2. The left side of the double-threaded rod 3 passes through the fixing frame 2 and extends to the outside of the fixing frame 2, where a gear 8 is fixedly sleeved. A connecting frame 4 is threadedly sleeved on the outer surface of the double-threaded rod 3. The outer surface of the connecting frame 4 is movably connected to the top of the water pressure plate body 1. A fixing plate 5 is fixedly connected to the left side of the water pressure plate body 1. A pull rod 6 is movably sleeved inside the fixing plate 5. The top of the pull rod 6 passes through the fixing plate 5 and extends above the fixing plate 5, where a locking block 7 is fixedly connected. The top of the locking block 7 meshes with the outer surface of the gear 8. A spring 9 is movably sleeved on the outer surface of the pull rod 6. The bottom end of the spring 9 is fixedly connected to the outer surface of the pull rod 6, and the top end of the spring 9 is fixedly connected to the bottom of the fixing plate 5.

[0028] When the lever 6 is pulled, the lever 6 will cause the locking block 7 to move vertically downward under the limiting action of the fixed plate 5, causing the locking block 7 to disengage from the outer surface of the gear 8. At this time, the fixing effect on the gear 8 will be released. Then, rotating the double threaded rod 3 will cause the two connecting brackets 4 to move horizontally towards each other along the inside of the fixed bracket 2.

[0029] Among them, the inner fixed sleeve of the fixed frame 2 is fitted with the limiting rod 10, and the outer surface of the limiting rod 10 is fitted with the inner movable sleeve of the connecting frame 4.

[0030] Due to the limiting effect of the limiting rod 10, the connecting frame 4 will move horizontally left and right.

[0031] The top of both the fixed frame 2 and the connecting frame 4 is fixedly connected to the mounting frame 11. The mounting frame 11 is threaded with a threaded rod 12. The left end of the threaded rod 12 passes through the mounting frame 11 and extends into the interior of the mounting frame 11 and is movably connected to the connecting block 13. The left end of the connecting block 13 is hinged to the diagonal rod 14, and the other end of the diagonal rod 14 is hinged to the vertical plate 15.

[0032] When the first threaded rod 12 is rotated, it will press and push the connecting block 13, causing the connecting block 13 to move to the left, which in turn causes the diagonal rod 14 to move and the vertical plate 15 to move downward.

[0033] There are four vertical plates 15. The bottom of the four vertical plates 15 passes through the fixing frame 2 and the connecting frame 4 respectively and extends into the interior of the fixing frame 2 and the connecting frame 4. They are respectively fixedly connected to the first pressure plate 16 and the second pressure plate 17. The bottom of the first pressure plate 16 is fixedly connected to the first triangular plate 18 and the vertical rod 19.

[0034] When the vertical plate 15 moves vertically downward under the limiting action of the fixed frame 2, it will drive the first triangular plate 18 and the vertical rod 19 to move together.

[0035] The water pressure plate body 1 has two sliding grooves 20 and two circular grooves 21 on the front and rear sides of the top. The two sliding grooves 20 are the same size.

[0036] When the first triangular plate 18 and the vertical rod 19 move downwards, they will cooperate with the sliding groove 20 and the circular groove 21 respectively to achieve the pressing and sealing effect.

[0037] Among them, the top left and right sides of the fixed frame 2 are threaded with the No. 2 threaded rod 22. The bottom of the No. 2 threaded rod 22 passes through the fixed frame 2 and extends into the interior of the fixed frame 2, and is movably sleeved with the No. 3 pressure plate 23.

[0038] When the second threaded rod 22 is rotated, it will cause the second threaded rod 22 to squeeze and push the third pressure plate 23 to move vertically downward.

[0039] Among them, the top left and right sides of the third pressure plate 23 are fixedly connected with fixing rods 24. The top of the fixing rods 24 passes through the fixing frame 2 and extends to the top of the fixing frame 2 and is movably connected with the inside of the fixing frame 2.

[0040] Due to the limiting effect of the fixing rod 24, the third pressure plate 23 will move vertically up and down.

[0041] Among them, the bottom of the third pressure plate 23 is fixedly connected to the second triangular plate 25, and the outer surface of the second triangular plate 25 is rough.

[0042] When the third pressure plate 23 moves vertically downward, the second triangle plate 25 will move together, and due to the design of the second triangle plate 25, the fixing effect of the second triangle plate 25 is improved.

[0043] The top of the water pressure plate body 1 is movably connected to a rubber pad 27, and the front of the water pressure plate body 1 is fixedly sleeved with a water injection pipe 28. The other end of the water injection pipe 28 passes through the water pressure plate body 1 and extends into the interior of the water pressure plate body 1.

[0044] When water is injected into the rubber pad 27 through the water injection pipe 28, the rubber pad 27 will gradually expand and provide pressure to the belt vulcanizing machine.

[0045] Among them, the four corners of the top of the water pressure plate body 1 are provided with horizontal grooves 26, and the outer surface of the horizontal grooves 26 is rough.

[0046] This design improves the fixing effect on the rubber pad 27 when the second triangular plate 25 is matched with the horizontal groove 26.

[0047] Working principle and usage process of this utility model:

[0048] First, place the rubber pad 27 to be fixed on top of the water pressure plate body 1 and pull the lever 6. At this time, the spring 9 will be compressed, which will cause the lever 6 to drive the locking block 7 to move vertically downward under the limiting action of the fixing plate 5, so that the locking block 7 is disengaged from the outer surface of the gear 8. At this time, the fixing effect on the gear 8 will be released. Then, rotate the double threaded rod 3, which will cause the two connecting frames 4 to move horizontally towards each other along the inside of the fixing frame 2 under the limiting action of the limiting rod 10. This achieves the purpose of adjusting the distance between the two connecting frames 4 and enables the device to fix rubber pads 27 of different widths, thus improving the application range of the device.

[0049] Then, rotating the first threaded rod 12 will cause it to press and push the connecting block 13 to move horizontally to the left, causing the inclined rod 14 to move. At this time, under the limiting action of the fixing frame 2 and the connecting frame 4, the four vertical plates 15 will move vertically downwards, respectively, and will drive the first pressure plate 16 and the second pressure plate 17 to move vertically downwards. At this time, the first triangular plate 18 and the vertical rod 19 will cooperate with the sliding groove 20 and the circular groove 21, thereby achieving a sealing effect around the rubber pad 27, without the need for multiple sets of bolts and nuts for fixing. This improves the efficiency of the operator in fixing the rubber pad 27 and reduces the operator's labor intensity. If the width of the rubber pad 27 is too wide, exceeding the width of the first pressure plate 16, and thus the vertical rod 19 cannot achieve the sealing effect on the left and right sides of the rubber pad 27, then rotating the second threaded rod 22 will cause the third pressure plate 23 to drive the second triangular plate 25 to move vertically downward under the limiting action of the fixed rod 24, and finally cooperate with the horizontal groove 26, thereby achieving the pressing and sealing effect on the rubber pad 27 that exceeds the width on both sides of the first pressure plate 16.

[0050] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
