Description

Technical Field

[0001] This utility model relates to the field of dimming film processing technology, and more specifically, to a dimming film processing device. Background Technology

[0002] The dimming film main unit is equipped with a front ITO film feeding device and a rear ITO film feeding device above it, with a front rubber roller and a rear rubber roller in the middle. The ITO film on the feeding device is inserted between the rubber rollers, tightened and squeezed, and then the front rubber roller is turned on and off, tightly adhering to the rear rubber roller. Above the rubber rollers are liquid crystal blocking devices, liquid crystal tubes, aluminum profile supports, aluminum profile support bases, connecting plates, etc. The liquid crystal blocking devices are located at both ends of the ITO film on the rubber rollers. There are two types of liquid crystal blocking devices: brush type and brush-improved type. The brush-improved type liquid crystal blocking device has grooves for vertical adjustment. The frame has a slot for left-right adjustment, and the aluminum profile bracket has a slot for front-back adjustment. Screws are installed in the slots of the improved brush-shaped liquid crystal blocker, the aluminum profile bracket, and the aluminum profile bracket, which are fixed together by a connecting plate. The brush-shaped liquid crystal blocker is fixed to the aluminum profile bracket with wire or metal wire. The bottom of the aluminum profile bracket is fixed to the dimming film host with foot screws. The liquid crystal tubes are set in the positions between the liquid crystal blockers. Some liquid crystal tubes are directly fixed to the aluminum profile bracket and the liquid crystal blocker. Others have an electric sliding device added to the dimming film host to drive the liquid crystal tubes to move automatically and reciprocally between the liquid crystal blockers.

[0003] The above operation has the following problems in practice: 1. The aluminum profile bracket cannot be adjusted vertically; the only way to adjust it is to set a slot on the liquid crystal blocker. This increases the difficulty and cost of manufacturing the liquid crystal blocker, and the head of the liquid crystal blocker is very easy to fall off. More critically, the screws in the slot of the liquid crystal blocker are very easy to loosen. Once loose, they will be rolled into the dimming film main unit roller. Since the slot part of the liquid crystal blocker is made of metal, when the metal material is rolled into the roller, it will cause the roller to deform, twist, and become unusable. 2. The liquid crystal flow rate of the dimming film is controlled by a peristaltic pump. The liquid crystal tube cannot control the liquid crystal outflow, which directly leads to the continuous filling of the liquid crystal tube with foam. Many small round bubbles appear on the liquid crystal on the surface of the ITO film, resulting in cavitation in the dimming film and a sharp increase in the defect rate of the dimming film.

[0004] Therefore, a dimming film processing device is proposed. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a dimming film processing device to solve the problems mentioned in the background art.

[0006] To achieve the above object, the present utility model provides the following technical solution: A dimming film processing device, including a square tube seat, a square tube clamp, a liquid crystal blocker body, a liquid crystal outflow body, a liquid crystal tube, and a square tube body. The square tube seat is fixedly connected to the dimming film main machine through a first screw at the bottom;

[0007] The square tube clamp is in the shape of a "mouth" - shaped frame, with liquid crystal blocker holes and liquid crystal outflow holes provided on its upper side and lower side respectively, square tube holes provided on its front side and rear side, and screw holes provided on its left side;

[0008] The liquid crystal blocker body is in a brush - like structure and is installed in the liquid crystal blocker hole. The liquid crystal outflow body is installed in the liquid crystal outflow hole, and the square tube body passes through the square tube hole;

[0009] The liquid crystal outflow body includes a liquid crystal tube sleeve and a liquid crystal flow control screw. A through - hole is provided at the center of the liquid crystal tube sleeve, and a screw hole communicating with the through - hole is provided on the side. The liquid crystal tube is arranged in the through - hole, and the liquid crystal flow control screw presses against the liquid crystal tube through the screw hole to adjust the liquid crystal flow;

[0010] The square tube clamp fixes the liquid crystal blocker body, the liquid crystal outflow body, and the square tube body through a second screw. A washer is provided at the top of the second screw, and an annular ring is provided at the tail.

[0011] Preferably, the liquid crystal blocker body is made of polytetrafluoro material.

[0012] Preferably, the square tube body is a flat square tube, with a hollow tube provided inside, and the liquid crystal tube passes through the hollow tube.

[0013] Preferably, a double - tube clamp is provided outside the square tube clamp, and the liquid crystal outflow body is installed inside the double - tube clamp.

[0014] Preferably, the adjustment range of the liquid crystal flow control screw is less than the natural flow of the liquid crystal tube, for achieving bubble - free liquid crystal output.

[0015] The technical effects and advantages of the present utility model:

[0016] By arranging the liquid crystal blocker body and the liquid crystal outflow body at both the top and bottom of the square tube clamp, up - and - down adjustment is achieved. There is no need to set slots on the liquid crystal blocker body, reducing the manufacturing difficulty and cost, and at the same time avoiding a series of problems caused by screw loosening.

[0017] By providing a liquid crystal flow control screw on the liquid crystal outflow body, the flow can be accurately controlled by pressing against the liquid crystal tube, and the adjustment range is less than the natural flow of the liquid crystal tube, achieving bubble - free output of the liquid crystal for the dimming film and reducing the defective rate of the dimming film.

[0018] The square tube body adopts a flat square tube design with a hollow tube inside for inserting the liquid crystal tube. This not only saves materials but also shortens the clamping length. At the same time, the hollow tube can prevent the liquid crystal tube from being wound into the roller, thus improving the safety and stability of the device.

[0019] The square tube clamp secures all components with a second screw. The top of the second screw has a washer to prevent loosening, and the tail has an annular ring to facilitate tightening, making the installation and disassembly of the device more convenient and improving work efficiency. At the same time, a double tube clamp is added to the outside of the square tube clamp to install the second liquid crystal outlet body, realizing dual flow control and further improving the control accuracy of liquid crystal flow.

[0026] 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.

[0027] Example 1: As shown in the attached document Figure 1 , Figure 3 , Figure 4 and Figure 5The diagram shows a dimming film processing device, which includes a square tube base 1, a square tube clamp 6, a liquid crystal blocker body 10, and a liquid crystal efferent body 3. The square tube clamp 6 fixes the square tube body 4 into the square tube hole by a second screw 12. A hollow tube 5 is provided inside the square tube body 4, through which the liquid crystal tube passes to prevent the roller from getting caught. The liquid crystal efferent body 3 is installed at the bottom of the square tube clamp 6 through a screw hole, and its liquid crystal flow control screw 9 presses against the liquid crystal tube to precisely control the flow rate. The liquid crystal blocker body 10 is installed at the top of the square tube clamp 6, is made of polytetrafluoroethylene, and is fixed by a second screw 12 and a washer 11 to prevent loosening. The tail of the second screw 12 is provided with a handle or ring 2 for easy tightening.

[0028] In specific implementation, the system comprises a square tube body 4, a square tube clamp 6, a liquid crystal blocker body 10, a liquid crystal efferent body 3, a liquid crystal tube, and a square tube base 1. The liquid crystal blocker body 10 is brush-shaped, and the liquid crystal tube is a transparent flexible tube installed between the liquid crystal blocker bodies 10. A first screw 7 is installed at the bottom of the square tube base 1 to fix it to the dimming film host. The square tube clamp 6 is a "U"-shaped frame with liquid crystal blocker holes and liquid crystal efferent holes on the upper and lower sides, respectively, square tube holes on the front and rear sides, and screw holes on the left side. The liquid crystal blocker body 10 is installed in the liquid crystal blocker hole, and the liquid crystal efferent hole is installed in the liquid crystal efferent hole. The liquid crystal outlet body 3 has a square tube body 4 installed in a square tube hole and a screw installed in a screw hole. Each second screw 12 fixes the liquid crystal blocker body 10, the liquid crystal outlet body 3, and the square tube body 4 respectively. The liquid crystal outlet body 3 consists of a liquid crystal tube sleeve and a liquid crystal flow control screw 9. A through hole is provided at the center of the liquid crystal tube sleeve, and a screw hole is provided on the side of the liquid crystal tube sleeve. The screw hole is connected to the through hole. The liquid crystal tube is installed in the through hole, and the liquid crystal flow control screw 9 is installed in the screw hole. When the liquid crystal flow control screw 9 enters the through hole, the top surface of the screw presses against the liquid crystal tube, and the liquid crystal outflow in the liquid crystal tube is controlled.

[0029] Example 2: As shown in the attached document Figure 2 As shown, the difference between the dimming film processing device provided in this embodiment 2 and that in embodiment 1 is that a double tube clamp 8 is added to the outside of the square tube clamp 6. The second liquid crystal efferent body 3 is installed on the inside of the double tube clamp 8. Dual flow control is achieved by adjusting the two liquid crystal flow control screws 9. The square tube body 4 and the square tube seat 1 are fixedly connected by the square tube clamp 6. The flat square tube design saves materials and shortens the clamping length.

[0030] In specific implementation, a double-tube clamp 8 can be set on the outer side of the dimming film liquid crystal blocker body 10, and a liquid crystal efferent body 3 is set on the inner side of the double-tube clamp 8. A square tube clamp 6 is set between the square tube body 4 and the square tube seat 1. A hollow tube 5 is set on the square tube body 4. The liquid crystal tube passes through the hollow tube 5 to prevent the liquid crystal tube from being wound into the roller. Since the liquid crystal blocker body 10 and the liquid crystal efferent body 3 are set at the top and bottom of the square tube clamp 6, the vertical adjustment is realized, and there is no need to set a slot on the liquid crystal blocker body 10. Since a control valve is set on the liquid crystal tube sleeve, the flow rate of the control valve is less than the flow rate of liquid crystal in the liquid crystal tube. When the liquid crystal tube is filled with liquid crystal, bubble-free output of the dimming film liquid crystal is realized.

[0031] The above description is only a preferred embodiment of the present utility model and is 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 should be included within the protection scope of the present utility model.
