Description

Technical Field

[0001] This utility model relates to the field of screen tensioning technology, and in particular to an automatic tensioning machine for guar gum screens. Background Technology

[0002] A screen tensioning machine is a specialized piece of equipment used for precisely tensioning and fixing screens. It is widely used in industries such as chemical, food, mining, environmental protection, and pharmaceutical. Its core function is to ensure that the screen is flat and has uniform tension, thereby improving screening efficiency, extending screen life, and reducing the failure rate during production.

[0003] However, existing automatic tensioning machines for guar gum screens do not provide uniform tension on the screens during use, which can easily lead to inconsistent screen apertures due to uneven tension at different points on the screen. Therefore, an automatic tensioning machine for guar gum screens is needed. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic tensioning machine for guar gum screens, which solves the problem in the existing technology that the tensioning force of the screen is not uniform during use, and the screen aperture is easily different due to the inconsistent tension in different parts of the screen.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic stretching machine for guar gum screens, comprising support legs and a stretching mechanism installed above the support legs, wherein the stretching mechanism comprises a transverse stretching component and a longitudinal stretching component;

[0006] The lateral tensioning assembly includes a body, side cavities, hydraulic airbags, inlet pipes, outlet pipes, a first oil valve, an oil pump, a front plate, side telescopic plates, sliders, grooves, and clamps. The body is fixedly mounted on the top of the outrigger. Side cavities are evenly distributed along the sides of the body. Hydraulic airbags are fixedly mounted inside the side cavities. An inlet pipe is installed at the bottom of the hydraulic airbag, and an outlet pipe is installed to the right of the bottom inlet pipe. Both the inlet and outlet pipes are connected to the inside of the first oil valve. An oil pump is installed along the side of the first oil valve. A front plate is mounted behind the oil pump. The front plate is fixed to the outrigger. Side telescopic plates are movably contacted around the body. Sliders are fixedly mounted on the inner walls of the side telescopic plates. Grooves are formed at the top of the body corresponding to the sliders. Clamps are mounted on the sides of the side telescopic plates.

[0007] The longitudinal tensioning assembly includes a fixed base plate, a second airbag, a working plate, a lifting groove, an oil inlet pipe, an oil outlet pipe, an oil outlet main pipe, an oil inlet main pipe, and a second oil valve. The fixed base plate is fixedly installed on the inner wall of the machine body. The second airbag is fixedly installed above the fixed base plate. The working plate is installed parallel to the second airbag. The lifting groove is opened on the bottom surface of the working plate at the position corresponding to the second airbag. The oil inlet pipe is installed in flow through the bottom of the second airbag. The oil outlet pipe is installed in flow through the top of the second airbag. The oil outlet main pipe is fixedly installed in front of the oil outlet pipe. The oil inlet main pipe is installed in flow through the front of the oil inlet pipe. The oil outlet main pipe and the oil inlet main pipe are both fixed to the second oil valve. The second oil valve is fixed to the front plate.

[0008] Preferably, the side telescopic plate forms a sliding structure with the machine body through the cooperation between the slider and the slide groove, and the dimensions of the side telescopic plate and the machine body match each other.

[0009] Preferably, the side telescopic plate forms a translational structure with the machine body via a hydraulic airbag, and the hydraulic airbag forms a telescopic structure through the cooperation between the inlet pipe and the outlet pipe.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] like Figure 1-5 As shown in the figure, an automatic guar gum screen stretching machine includes a support leg 1 and a stretching mechanism installed above the support leg 1. The stretching mechanism includes a transverse stretching component and a longitudinal stretching component.

[0025] The transverse tensioning assembly includes a body 2, side cavities 3, hydraulic airbags 4, inlet pipes 5, outlet pipes 6, a first oil valve 7, an oil pump 8, a front plate 9, side telescopic plates 10, sliders 11, slide grooves 12, and clamps 13. The body 2 is fixedly mounted on the top of the outriggers 1. Side cavities 3 are evenly distributed along the sides of the body 2. Hydraulic airbags 4 are fixedly mounted inside the side cavities 3. An inlet pipe 5 is installed at the bottom of the hydraulic airbag 4, and a... The liquid outlet pipe 6, the liquid inlet pipe 5 and the liquid outlet pipe 6 are all connected to the inside of the first oil valve 7. An oil pump 8 is installed on the side of the first oil valve 7. A front plate 9 is installed behind the oil pump 8. The front plate 9 is fixed to the support leg 1. Side telescopic plates 10 are movably contacted around the body 2. A slider 11 is fixedly installed on the inner wall of the side telescopic plate 10. A groove 12 is opened on the top of the body 2 at the position corresponding to the slider 11. Clips 13 are installed on the sides of the side telescopic plate 10.

[0026] The longitudinal tensioning assembly includes a fixed base plate 14, a second airbag 15, a working plate 16, a lifting groove 17, an oil inlet pipe 18, an oil outlet pipe 19, an oil outlet main pipe 20, an oil inlet main pipe 21, and a second oil valve 22. The fixed base plate 14 is fixedly installed on the inner wall of the machine body 2. The second airbag 15 is fixedly installed above the fixed base plate 14. The working plate 16 is installed parallel above the second airbag 15. The lifting groove 17 is opened on the bottom surface of the working plate 16 at the position corresponding to the second airbag 15. The oil inlet pipe 18 is installed in the bottom of the second airbag 15. The oil outlet pipe 19 is installed in the top of the second airbag 15. The oil outlet main pipe 20 is fixedly installed in front of the oil outlet pipe 19. The oil inlet main pipe 21 is installed in the front of the oil inlet pipe 18. The oil outlet main pipe 20 and the oil inlet main pipe 21 are both fixed to the second oil valve 22. The second oil valve 22 is fixed to the front plate 9.

[0027] The side telescopic plate 10 forms a sliding structure with the body 2 through the cooperation between the slider 11 and the slide groove 12. The dimensions between the side telescopic plate 10 and the body 2 are mutually matched. The side telescopic plate 10 can slide and adjust its position relative to the body 2 by sliding inside the slide groove 12 through the slider 11 installed on the inner wall. The four sets of side telescopic plates 10 installed on the side of the body 2 can move outward. During the movement, it can not only slide through the slider 11, but also limit the position of the side telescopic plate 10 inside the device through the slide groove 12 to prevent the side telescopic plate 10 from shifting inside the device.

[0028] The side telescopic plate 10 forms a translational structure with the hydraulic airbag 4 and the machine body 2. The hydraulic airbag 4 forms a telescopic structure through the cooperation between the inlet pipe 5 and the outlet pipe 6. A piston is installed inside the hydraulic airbag 4 between the inlet pipe 5 and the outlet pipe 6. Under the drive of the oil pump 8, hydraulic oil is injected into the inlet pipe 5 through the first oil valve 7. After the hydraulic oil is injected, the hydraulic airbag 4 will expand and extend outward under the high pressure of the hydraulic oil. The hydraulic airbag 4 and the side telescopic plate 10 are fixed to each other. Therefore, the side telescopic plate 10 will drive the hydraulic airbag 4 to move evenly to the outside. Adjusting the distance between the four sets of side telescopic plates 10 makes it convenient to tighten the Guar screen fixed by the clamp 13.

[0029] Example 2

[0030] like Figure 4 and Figure 5 As shown, this embodiment further illustrates Example 1. The fixed base plate 14 is fixed to the body 2. The fixed base plate 14 has a hollow structure. Multiple second airbags 15 can be arranged in an array on the edge of the fixed base plate 14. The second airbags 15 drive the working plate 16 to rise and fall under the drive of the oil outlet pipe 20 and the oil inlet pipe 21, thereby adjusting the height of the working plate 16 inside the device.

[0031] The working plate 16 forms a covering structure with the second airbag 15 through the lifting groove 17. The second airbag 15 is arrayed on the top of the fixed base plate 14. The lifting groove 17, which is evenly opened at the bottom of the working plate 16, includes the second airbag 15 inside. The second airbag 15 is evenly installed inside the lifting groove 17, so that the second airbag 15 can evenly drive the working plate 16 to rise and fall when it is raised and lowered, thus avoiding the working plate 16 from tilting inside the device and affecting its use.

[0032] Inside the second airbag 15, a piston is installed between the oil outlet pipe 19 and the oil inlet pipe 18. The second airbag 15 is fixed to the working plate 16. The working plate 16 forms a lifting structure through the second airbag 15. Driven by the second oil valve 22 and the oil pump 8, hydraulic oil is injected into the second airbag 15 through the oil inlet manifold 21 and the oil inlet pipe 18. Under high pressure, the injected hydraulic oil causes the second airbag 15 to rise and increase its height. Since the second airbag 15 is fixed to the working plate 16, the working plate 16 will adjust its height inside the device. Then, the hydraulic oil is output through the oil outlet pipe 19 and the oil outlet manifold 20 to restore the working plate 16 to its original height inside the device.

[0033] Working principle: First, the guar screen is fixed to the top of the device using clamp 13. Driven by oil pump 8, hydraulic oil is injected into the inlet pipe 5 through the first oil valve 7. After the hydraulic oil is injected, the hydraulic airbag 4 expands and extends outward under the high pressure of the hydraulic oil. The hydraulic airbag 4 is fixed to the side telescopic plate 10, so the side telescopic plate 10 will move evenly outward under the action of the hydraulic airbag 4. Adjusting the distance between the four sets of side telescopic plates 10 tightens the guar screen. At the same time, the side telescopic plate 10 can slide in the slide groove 12 through the slider 11 installed on the inner wall to adjust its position relative to the machine body 2. The four sets of side telescopic plates 10 installed on the side of the machine body 2 can... The device moves outwards, and during this movement, it can slide not only through the slider 11, but also through the slide groove 12 to limit the position of the side telescopic plate 10 inside the device, preventing the side telescopic plate 10 from shifting inside the device. Then, driven by the second oil valve 22 and the oil pump 8, hydraulic oil is injected into the second airbag 15 through the oil inlet manifold 21 and the oil inlet pipe 18. The injected hydraulic oil causes the second airbag 15 to rise and increase its height under high pressure. Since the second airbag 15 and the working plate 16 are fixed to each other, the working plate 16 will adjust its height by raising and lowering inside the device. Then, the hydraulic oil is output through the oil outlet pipe 19 and the oil outlet manifold 20 to restore the height of the working plate 16 inside the device.
