Therefore, various parts and tools are required. It is necessary to understand the names and usage methods of each part and be familiar with the structure of the tent in order to quickly and conveniently set up the tent. The tent cloth needs to be rolled up during the production process. In the current tent cloth rolling device, during the cloth rolling process, the rolled tent cloth has wrinkles due to the thick tent cloth, and the winding tightness is not enough and it is easy to loosen. Therefore, in order to solve the deficiencies in the prior art, a tent cloth quick rolling device with a simple structure needs to be designed. Utility Model Content

[0009] Compared with the prior art, the tent cloth fast rolling device of the utility model has the following beneficial effects:

[0010] When the winding roller is winding the tent cloth, the surface of the tent cloth is pre-tightened by the pre-tightening assembly on the right side to ensure the tightness of the winding. When the pre-tightening pressure is less than a certain value, the diameter of the tent cloth roll on the winding roller becomes larger, and the thrust of the sliding sleeve to move to the right is smaller than the pre-tightening force of the heavy hammer on the rotating baffle. The rotating baffle presses against the sliding sleeve, and the pressure wheel at the left end continues to push the surface of the tent cloth, and the sliding rod moves to the right inside the sliding sleeve and compresses the spring 1; when the pre-tightening pressure is greater than a certain value, the elastic force of the spring 1 is prevented from being too large when the winding diameter is too large, resulting in excessive pre-tightening force and excessive compression of the tent cloth, affecting the winding speed, and providing space for further winding. The diameter of the tent cloth roll on the winding roller becomes larger, and the thrust of the sliding sleeve to move to the right is greater than the pre-tightening force of the heavy hammer on the rotating baffle. The rotating baffle is pushed to the right and rotated into the groove. The sliding sleeve continues to move right in the fixed sleeve to a certain distance and then contacts the extrusion push rod. The push rod moves to the right and compresses the spring 2, maintaining the pre-tightening force within a certain range for the winding and ensuring the winding speed.

[0017] The following is combined with the embodiments and attached Figures 1 to 3 , the technical solution of the utility model is further elaborated.

[0018] Example 1

[0019] A tent cloth fast winding device, comprising: a frame 1, a winding roller 2 and a pre-tightening component 3, wherein the winding roller 2 is arranged on the frame 1, and the pre-tightening component 3 is arranged on the right side of the winding roller 2. The pre-tightening component 3 comprises a fixed sleeve 31, a sliding sleeve 32, a sliding rod 33, a pressure wheel 34, a spring 1 35, an inner sleeve 36, a spring 2 37, a push rod 38, a rotating baffle 39 and a heavy hammer 4, wherein the inner sleeve 36 is fixed to the inner right end of the fixed sleeve 31, the spring 2 37 is located inside the inner sleeve 36, and the right end of the push rod 38 is slidably arranged on the inner sleeve 36 The sliding sleeve 32 is slidably arranged inside the fixed sleeve 31 and is located on the left side of the push rod 38. The spring 1 35 is located in the sliding sleeve 32. The slide rod 33 is slidably arranged in the sliding sleeve 32 and is located on the left side of the spring 1 35. The pressure wheel 34 is arranged on the left side of the slide rod 33. The rotating baffle 39 is rotatably connected to the groove 311 of the fixed sleeve 31. The rotating baffle 39 is located between the sliding sleeve 32 and the push rod 38. The heavy hammer 4 is connected to the shaft 391 of the rotating baffle 39 through a rope 41.

[0020] like Figure 1 to Figure 3As shown, the working principle of the utility model is as follows: when the winding roller 2 is winding the tent cloth, the surface of the tent cloth is pre-tightened by the pre-tightening component 3 on the right side to ensure the tightness of the winding. When the pre-tightening pressure is less than a certain value, the diameter of the tent cloth on the winding roller becomes larger, and the thrust of the sliding sleeve 32 to move to the right is less than the pre-tightening force of the heavy hammer 4 on the rotating baffle 39. The rotating baffle 39 presses against the sliding sleeve 32, and the pressure wheel 34 at the left end continuously pushes the surface of the tent cloth, and the sliding rod 33 moves right inside the sliding sleeve 32 and compresses the spring 1 35; when the pre-tightening pressure is greater than a certain value, it is prevented from rolling too large a diameter. The elastic force of spring 1 35 is too large, resulting in excessive preload and excessive compression of the tent cloth, affecting the winding speed while providing space for further winding. The diameter of the tent cloth roll on the winding roller increases, and the thrust of the sliding sleeve 32 to move to the right is greater than the preload of the heavy hammer 4 on the rotating baffle 39. The rotating baffle 39 is pushed to the right and rotates into the groove 311. The sliding sleeve 32 continues to move to the right in the fixed sleeve 31 to a certain distance and then contacts the extrusion push rod 38. The push rod 38 moves to the right and compresses the spring 2 37, maintaining the preload within a certain range for winding and ensuring the winding speed.

[0021] As a further preferred embodiment, a limit assembly 5 is provided on the frame 1, and the limit assembly 5 is symmetrically arranged and located on both sides of the winding roller 2. The limit assembly 5 includes a limit plate 51, a sliding rod 52 and a fixing bolt 53. The sliding rod 52 is slidably arranged on the frame 1, and the limit plate 51 is fixed on the inner side of the sliding rod 52. The fixing bolt 53 is fixed on the frame 1 and is used to fix the sliding rod 52. According to the width of the tent cloth, the position of the sliding rod 52 on the frame 1 is adjusted, so that the limit plate 51 is located on both sides of the tent cloth to ensure edge alignment during the winding process.

[0022] As a further preferred embodiment, a sliding frame 6 is provided at the right end of the fixing sleeve 31, and the sliding frame 6 includes a base 61, a slide plate 62 and a fastening bolt 63. The slide plate 62 is fixed to the right end of the fixing sleeve 31 and is slidably arranged on the base 61. The fastening bolt 63 is fixed to the base 61 and fixes the position of the slide plate 62. After the winding is completed, in order to facilitate the unloading of the tent cloth roll, the pre-tightening assembly 3 is moved to the right by the sliding frame 6 to increase the winding space.

[0023] As a further preferred embodiment, the sliding rod 52 and the fixing bolt 53 are symmetrically arranged in two groups to improve the stability of movement.

[0024] As a further preferred embodiment, the pressure wheel 34 is a rubber pressure wheel to reduce damage to the surface of the tent cloth.
