Description

Technical Field

[0001] The utility model belongs to the technical field of tarpaulin collection, in particular to a tarpaulin unfolding and reeling device. Background Art

[0002] Tarpaulin (or waterproof cloth) is a high-strength, tough and soft waterproof material, often used as canvas (oil canvas), polyester with polyurethane coating or made into polyethylene plastic.

[0003] When the existing tarpaulin unfolding and reeling device is in use, foreign matter and gravel will fall on the surface of the tarpaulin when the tarpaulin is unfolded. When the tarpaulin is reeled in, the gravel wrapped in the tarpaulin will cause friction and damage the tarpaulin, affecting the service life of the tarpaulin, making it difficult to clean and reducing its efficiency.

[0004] For example, in a self-expanding awning (authorization publication number CN 216861722 U), the gear drive assembly first drives the screw drive assembly, which then drives the slider connection assembly. The slider connection assembly then drives the rotating deployment assembly to deploy the visor. This allows the visor to be freely deployed or retracted without the need for flexible material to block it, improving the device's practicality. However, this device suffers from the following problem: during use, it cannot automatically clean debris adhering to the awning's surface, reducing its efficiency. Utility Model Content

[0005] The purpose of the utility model is to provide a tarpaulin unfolding and reeling device to solve the problems raised in the background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a tarpaulin unfolding and winding device, comprising: a mounting frame and a tarpaulin belt arranged inside the mounting frame; two connecting frames are welded to the vertical side surfaces of the mounting frame, a rotating motor is installed on the vertical inner wall of the mounting frame, a rotating rod is installed on the driving end of the rotating motor, and the tarpaulin belt is sleeved on the outer periphery of the rotating rod, a connecting plate is adhered to the end of the tarpaulin belt, a slider is welded to the vertical side surface of the connecting plate, a linear motor is installed on the vertical inner wall of one of the connecting frames, vertical plates are welded to the top and bottom ends of the other connecting frame, top plates are welded to the vertical side surfaces of the two vertical plates, a fixing frame is welded to the other side of the vertical plate, and a motor is installed on the top of the fixing frame;

[0007] The driving end of the motor is equipped with a bidirectional screw with its end inserted into the fixed frame. Two slides are sleeved on the outer periphery of the bidirectional screw. Moving plates are welded to the vertical sides of the two slides, and brushes are glued to the sides of the two moving plates that are close to each other.

[0008] In a further embodiment, the moving part of the linear motor is equipped with a moving block, and a limiting plate is welded between the two connecting frames.

[0009] In a further embodiment, the vertical side surface of the slider is threadedly connected with a fixing nail inserted into the moving block.

[0010] In a further embodiment, fixing plates are welded to both sides of the installation frame, and vertical side surfaces of the two fixing plates are provided with thread grooves.

[0011] In a further embodiment, vertical side surfaces of the two fixing plates are both in close contact with vertical frames, and thread grooves of the same size are formed on both sides of the vertical frames.

[0012] In a further embodiment, vertical inner walls of the two vertical frames are closely attached with connecting strips, and both sides of the two connecting strips are provided with thread grooves of the same size.

[0013] In a further embodiment, collars are welded to the top and bottom ends of the two connecting bars, and threaded rods are threadedly connected to the inner circumferences of the two collars.

[0014] Compared with the prior art, the technical effects and advantages of this utility model are:

[0015] During use, the tarpaulin unfolding and winding device is disassembled by removing the threads set in the thread groove, so that the vertical frame, connecting strip and fixing plate are out of control, thereby facilitating the disassembly of the device. At the same time, the positions corresponding to the multiple thread grooves and the fixing plate are adjusted so that the height of the tarpaulin belt can be adjusted up and down under the limitation of the vertical frame by the connecting strip.

[0016] The tarpaulin unfolding and winding device is used to insert a fixing nail into the side of the slider, and the fixing nail is inserted into the moving block, so that the moving block of the linear motor moving part drives the slider and the connecting plate to move, so that the rotating motor straightens the tarpaulin belt when the tarpaulin belt around the loose rotating rod is rotated, and then slowly and gradually retracts it. The fixing frame on the side of the vertical plate is used to control the slide plate around the bidirectional screw rod to move toward each other through the motor at the top of the fixing frame, so that the moving plates on both sides move toward each other, and the two moving plates are brought close to each other. The brush on one side clamps the tarpaulin belt, and in the process of gradually retracting the tarpaulin belt, the gravel and impurities attached to the surface of the tarpaulin belt are scraped off, and multiple operations can be performed. Unlike the existing device which cannot effectively clean the gravel and device attached to the surface of the tarpaulin belt, this device can automatically scrape off the gravel and impurities, saves manpower, prevents damage to the tarpaulin belt, and improves the use efficiency. The tarpaulin unfolding and reeling device can adjust the height of the tarpaulin belt up and down under the limit of the connecting bar on the vertical frame, and can automatically scrape off gravel and impurities, saving manpower, preventing the tarpaulin belt from being damaged, and improving utilization efficiency.

A connecting plate 23 is bonded to the end of the tarpaulin belt 10. A slider 3 is welded to the vertical side surface of the connecting plate 23. A linear motor 5 is installed on the vertical inner wall of one of the connecting frames 2. Vertical plates 22 are welded to the top and bottom ends of the other connecting frame 2. Top plates 7 are welded to the vertical sides of the two vertical plates 22. A fixing frame 19 is welded to the other side of the vertical plate 22. A motor 17 is installed on the top of the fixed frame 19, and fixing nails are inserted into the side surfaces of the slider 3. 4. Insert the fixing nail 4 into the moving block so that the moving block of the moving part of the linear motor 5 drives the slider 3 and the connecting plate 23 to move, so that the rotating motor 21 straightens the tarpaulin belt 10 while loosening the rotating rod 20 around the tarpaulin belt 10, and then slowly and gradually retracts it. Use the fixed frame 19 on the side of the vertical plate 22 and the motor 17 at the top of the fixed frame 19 to control the slide plate 18 on the periphery of the bidirectional screw to move toward each other, so that the moving plates 8 on both sides move toward each other, and move the two moving plates 8 close to each other. The brush 9 on one side fits to clamp the tarpaulin belt 10. In the process of gradually recovering the tarpaulin belt 10, the gravel and impurities attached to the surface of the tarpaulin belt 10 are scraped off. Multiple operations can be performed, and a collection box can be installed at the bottom end of the tarpaulin belt 10 to collect gravel and impurities.

[0029] This is different from the existing device which cannot effectively clean the gravel and impurities attached to the surface of the tarpaulin belt 10. The device can automatically scrape off the gravel and impurities, saving manpower, preventing the tarpaulin belt 10 from being damaged, and improving the efficiency of use. The driving end of the motor 17 is equipped with a bidirectional screw rod with an end inserted into the interior of the fixed frame 19. The outer periphery of the bidirectional screw rod is sleeved with two slides 18. The vertical sides of the two slides 18 are welded with a movable plate 8 located between the two top plates 7, and the two movable plates 8 are bonded with a brush 9 on the side close to each other.

[0030] The moving part of the linear motor 5 is installed with a moving block, and a limiting plate 14 is welded between the two connecting frames 2. The vertical side of the slider 3 is threadedly connected with a fixing nail 4 inserted into the moving block. Fixed plates 15 are welded on both sides of the installation frame 16.

The vertical inner walls of the two vertical frames 1 are tightly attached to the connecting strips 6, and the two connecting strips 6 are provided with threaded grooves 12 of the same size on both sides. The top and bottom ends of the two connecting strips 6 are welded with rings 13, and the inner circumferences of the two rings 13 are threadedly connected with threaded rods 11. The threaded rods 11 are inserted into the wall, so that the connecting strips 6 are fixed with the rings 13.

[0031] The linear motor 5, motor 17 and rotary motor 21 are all conventional instruments. Their working principles, sizes and models are irrelevant to the functions of this application, so they will not be described in detail. The control method of the present invention is controlled by a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0032] How it works

[0033] The tarpaulin unfolding and reeling device inserts a fixing nail 4 into the side of the slider 3, and inserts the fixing nail 4 into the moving block, so that the moving block of the moving part of the linear motor 5 drives the slider 3 and the connecting plate 23 to move, so that the rotating motor 21 straightens the tarpaulin belt 10 while loosening the tarpaulin belt 10 around the rotating rod 20, so that the tarpaulin belt 10 is unfolded;

[0034] When winding, remove the fixing nail 4, and the rotating motor 21 controls the tarpaulin belt 10 to retract slowly and gradually. Utilize the fixing frame 19 on the side of the vertical plate 22, and the motor 17 at the top of the fixing frame 19 controls the slide plate 18 on the periphery of the bidirectional screw rod to move toward each other, so that the movable plates 8 on both sides move toward each other, and the two movable plates 8 are brought close to each other. The brush 9 on one side fits to clamp the tarpaulin belt 10. In the process of gradually retracting the tarpaulin belt 10, the gravel and impurities attached to the surface of the tarpaulin belt 10 are scraped off, and the operation can be performed multiple times.
