[0024] By adopting the above technical scheme, the self-weight type storage rack has the following beneficial effects:

[0025] In the utility model, when the operator replaces the winding roller for winding the sheet material, the tension of the sheet material is reduced, the sheet material around the lower guide roller is caused to start descending along the vertical moving rod because the self-weight of the lower guide roller mounting frame and the lower guide roller is greater than the tension of the sheet material, thereby starting to store the sheet material accumulated in the production process, and pollution and waste caused by the contact of the sheet material with the ground are avoided.

[0026] In addition, the buffer spring is arranged on the vertical moving rod, the rapid descending and collision caused by the sudden rupture of the sheet material are effectively avoided, the pad block is arranged on the rack to prevent the collision between the lower guide roller mounting frame and the rack when the lower guide roller mounting frame rises.

[0027] In conclusion, the utility model adopts the gravity mode to solve the tension keeping problem of the sheet material in the winding change process, effectively stores the accumulated sheet material through reasonable structure design, avoids the pollution caused by the contact of the sheet material with the ground, and greatly saves the production cost and improves the production efficiency because of the absence of motor driving.

[0034] In order to make the content of the utility model more easily understood clearly, the utility model is further explained in detail below according to specific embodiment and in conjunction with the drawings.

[0035] As Figures 1-6As shown, a self-weight storage rack includes:

[0036] Rack 1;

[0037] Three upper guide rollers 2 are arranged at intervals in the horizontal direction and are rotatably mounted on the upper part of the frame 1;

[0038] A pair of vertical moving rods 3 are respectively installed on both sides of the frame 1;

[0039] The lower guide roller mounting frame 4 is slidably mounted on the vertical moving rod 3 at both ends.

[0040] A pair of lower guide rollers 5 are arranged in parallel along the horizontal direction and rotatably mounted on the lower guide roller mounting frame 4;

[0041] The upper guide roller 2 and the lower guide roller 5 are arranged alternately to form a guide channel, and the sheet is sequentially wound around the outer circumference of the upper guide roller 2 and the lower guide roller 5 along the guide channel.

[0042] In this embodiment, as Figures 1-5 As shown, when the operator changes the spool used for winding the sheet, the tension of the sheet decreases. Because the weight of the lower guide roller 5 and the lower guide roller 4 is greater than the tension of the sheet, the lower guide roller 5 begins to descend along the vertical moving rod 3, thus collecting the sheet accumulated during production and preventing contamination and waste caused by the sheet contacting the ground. Furthermore, the system does not rely on motor drive and utilizes its own weight for material storage, significantly reducing production costs and improving production efficiency.

[0043] Specifically, such as Figure 1 and Figure 3 As shown, the self-weight storage rack also includes a pair of pads 6, which are fixedly installed on the frame 1 and located directly above the lower guide roller mounting frame 4.

[0044] Specifically, such as Figures 1-3 As shown, the self-weight storage rack also includes a buffer spring 7, which is sleeved on the vertical moving rod 3. The lower end of the buffer spring 7 abuts against the frame 1, and the upper end of the buffer spring 7 is adapted to abut against the lower guide roller mounting frame 4 when the lower guide roller mounting frame 4 is in the bottom position.

[0045] Specifically, such as Figure 1 As shown, the self-weight storage rack also includes a protective door 8, which is installed on the side of the frame 1.

[0046] In this embodiment, as Figure 1 and Figure 3As shown, the cushion block 6 is made of rubber material, which can reduce the impact force generated by collision when the cushion block 6 abuts against the lower guide roller mounting frame 4, avoiding damage to the lower guide roller mounting frame 4 due to collision. When the sheet tension suddenly increases, the cushion block 6 can limit the upper limit position of the lower guide roller mounting frame 4, preventing the lower guide roller mounting frame 4 from exceeding the predetermined stroke.

[0047] The buffer spring 7 can play a buffering role during the descent of the lower guide roller mounting frame 4, slowing down the descent speed of the lower guide roller mounting frame 4, and preventing the lower guide roller mounting frame 4 from colliding violently with the bottom of the rack 1.

[0048] The protective door 8 can be made of transparent acrylic plate, which is convenient for operators to observe the internal running state of the storage rack. The protective door 8 is connected with the rack 1 through a hinge, and after opening the protective door 8, the internal structure of the storage rack can be repaired and maintained.

[0049] Specifically, as shown in Figure 1 and Figure 3 and Figure 5 As shown, the lower guide roller mounting frame 4 comprises:

[0050] A pair of guide sliding blocks 41, which are respectively slidably arranged on the corresponding vertical moving rods 3;

[0051] A pair of sliding plates 42, which are respectively fixedly installed on the corresponding guide sliding blocks 41;

[0052] A group of lower guide roller fixing seats 43, each of which is installed on the two sides of the corresponding sliding plate 42;

[0053] Among them, the two ends of the lower guide roller 5 are rotatably installed between the corresponding pair of lower guide roller fixing seats 43.

[0054] Specifically, as shown in Figures 5-6 The lower guide roller fixing seat 43 comprises:

[0055] A fixed block 431, which is fixedly installed on the sliding plate 42, and the fixed block 431 is provided with a U-shaped groove;

[0056] A fixed plate 432, which is installed on the fixed block 431 through a fastener, and the fixed plate 432 is adapted to close the U-shaped groove.

[0057] In this embodiment, as shown in Figures 3-6 The two ends of the lower guide roller 5 are installed in the U-shaped groove through a bearing, and the fixed plate 432 and the fixed block 431 are connected through a bolt, forming a closed bearing mounting cavity to prevent the bearing from falling off.

[0058] Specifically, as shown in Figure 5As shown in the figure, the guide slider 41 is provided with a plurality of threaded holes 421 in the vertical direction, the threaded holes 421 correspond to the mounting holes on the sliding plate 42, and the mounting height of the sliding plate 42 on the guide slider 41 is adjusted by rotating the threaded holes 421 in different positions through the fasteners.

[0059] In the embodiment, as shown in the figure, Figure 5 When adjusting, the fasteners are loosened first, the sliding plate 42 is moved to the appropriate height, the two sliding plates 42 are kept in the same horizontal plane, and then the fasteners are tightened for fixation.

[0060] The above-described specific embodiments further illustrate the technical problems, technical solutions and beneficial effects solved by the utility model, and it should be understood that the above-described specific embodiments are merely examples of the utility model and are not used to limit the utility model, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
