[0002] Film is usually made by high-temperature extrusion in a mixer. In order to ensure the quality and performance of the film, the extruded film generally needs to be cooled. However, the traditional film cooling method usually adopts flat drying.

[0003] The Chinese utility model patent with publication number CN207808146U discloses a film drying rack for rubber sealing ring production. The film drying rack in this technology can dry multiple films at the same time by setting up multiple layers of placement planes, thereby improving the drying efficiency. However, the existing film drying rack has a fixed structure in which the spacing between the multiple layers of placement planes is set. Due to the significant difference in the thickness of different films, thicker films require more spacious space to ensure sufficient drying to avoid mutual squeezing and deformation or uneven drying, while thinner films do not require too much space. Too much space may lead to reduced drying efficiency, so the fixed-spacing film drying rack has certain limitations in use.

[0004] Therefore, a kind of adjustable multi-layer rack for film drying is needed to solve the above problems. Utility Model Content

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] The utility model provides an adjustable multi-layer rack for drying films, such as Figure 1-Figure 6As shown, the multi-layer rack includes a base 1, brake universal wheels 11 fixedly arranged at the corners around the bottom of the base 1, a vertical frame 2 symmetrically fixedly arranged on one side of the top of the base 1, two horizontal frames 3 respectively fixedly arranged on the top and bottom of the two vertical frames 2, a plurality of flip grid frames 4 rotatably arranged on one side of the two vertical frames 2 and distributed in a linear array for drying films, and support legs 41 symmetrically arranged at the bottom of the flip grid frame 4 away from the vertical frame 2 for support; the multi-layer rack also includes a U-shaped frame 5 arranged between the flip grid frame 4 and the vertical frame 2, and a U-shaped frame 5 longitudinally sliding between the two vertical frames 2. A sliding frame 6 is fixedly connected to the U-shaped frame 5 on the side close to the vertical frame 2, a fixed frame 7 is fixedly arranged between the two vertical frames 2 and located below the sliding frame 6, and a driving component 8 is arranged on the fixed frame 7 for driving the sliding frame 6 to move; the support leg 41 includes a fixed column 411 fixedly installed at the bottom of the flipping frame 4 away from the U-shaped frame 5, an adjusting screw 412 longitudinally penetrating through the end of the fixing column 411 away from the flipping frame 4 and screwed to the fixing column 411, and an anti-sliding block 413 fixedly installed at the end of the adjusting screw 412 away from the fixed column 411.

[0034] When in use, through the design of the brake universal wheel 11, the multi-layer rack is first moved to a suitable position, and then the flip grid rack 4 at the bottom is rotated to make it rotate to a horizontal direction. At this time, the support feet 41 arranged on the bottom flip grid rack 4 can contact with the base 1 to ensure the stability of the horizontal placement of the bottom flip grid rack 4. Then, a single film to be dried is placed flat on the horizontally placed and bottom flip grid rack 4 for drying. If the number of films to be dried is large, multiple flip grid racks 4 can be rotated from bottom to top in sequence, and according to the above steps, the single films to be dried are placed in sequence on the flip grid racks 4 that are rotated to a horizontal position in sequence, so that Multiple films can be dried at the same time. At the same time, during the drying process, the driving component 8 of the corresponding flip grid 4 close to the side of the vertical frame 2 can be operated to adjust the up and down movement position of the sliding frame 6 connected to the corresponding flip grid 4, so as to indirectly adjust the spacing between multiple flip grids 4 to meet different drying needs. When the driving component 8 is used to adjust the spacing between multiple flip grids 4, the anti-sliding block 413 set on the side of the corresponding flip grid 4 away from the vertical frame 2 can be synchronously rotated to achieve height adjustment of the adjusting screw 412, so as to ensure that the support foot 41 can be adjusted as the spacing of the flip grid 4 is adjusted, and can always provide stable support for the flip grid 4 in the horizontal direction.

[0035] Specifically, a receiving groove 71 is provided at the position of the fixed frame 7 corresponding to the driving component 8; wherein the driving component 8 comprises a screw rod 81 which longitudinally penetrates the sliding frame 6 and the receiving groove 71 in sequence and is rotatably connected to the receiving groove 71, a second worm gear 82 which is rotatably arranged in the receiving groove 71 and is fixedly sleeved with the screw rod 81, a second worm gear 83 which transversely penetrates the receiving groove 71 and is rotatably connected to the fixed frame 7, and a second knob 84 which is arranged on the side of the fixed frame 7 away from the flipping grid 4 and is fixedly connected to the second worm gear 83, the second worm gear 83 is meshed with the second worm gear 82, and the sliding frame 6 is screwed with the screw rod 81; when it is necessary to adjust the spacing between the multiple flipping grids 4 according to the film drying requirements, it is only necessary to rotate the second knob corresponding to the flipping grid 4 on the side close to the stand 2. Button 84, since the second knob 84 is fixedly connected to the second worm 83, and the second worm 83 is meshed with the second worm wheel 82 connected to the screw rod 81, the screw rod 81 can rotate with the rotation of the second knob 84, and since the screw rod 81 is screwed to the sliding frame 6, and the sliding frame 6 is slidably set between the two vertical frames 2, therefore, when the corresponding second knob 84 is rotated, the corresponding sliding frame 6 will move up and down stably, and the sliding frame 6 is connected to the flip grid 4 through the U-shaped frame 5, therefore, when the corresponding sliding frame 6 slides up and down, the corresponding flip grid 4 will also slide up and down synchronously, so that the up and down position of each flip grid 4 can be adjusted individually according to the drying needs, and after adjustment, stop rotating the second knob 84.

[0036] In addition, in order to ensure the stability of the longitudinal movement of the sliding frame 6, a sliding groove 21 is opened on the side where the two vertical frames 2 are close to each other, and the two ends of the sliding frame 6 are respectively slidably connected in the two sliding grooves 21; the design of the sliding groove 21 can provide a clear guide for the sliding frame 6, so that the sliding frame 6 can only move in a straight line along the direction of the sliding groove 21, so as to avoid the displacement or distortion of the sliding frame 6 during the movement, and ensure the accuracy and precision of the adjustment.

[0037] It should be noted that the driving components 8 arranged on the side of the multiple flip grids 4 close to the vertical frame 2, the top ends of the screw rods 81 arranged on two adjacent driving components 8 are in contact with the bottom ends of the adjacent fixed frame 7. This design can prevent the sliding frame 6 from sliding off the screw rods 81.

[0038] Furthermore, a rotating component 51 for driving the flip grid 4 to rotate is provided on the U-shaped frame 5, and the rotating component 51 includes a mounting box 511 fixedly installed on one side of the U-shaped frame 5, a rotating shaft 512 which sequentially passes through the U-shaped frame 5 and the mounting box 511 transversely and is fixedly connected to the flip grid 4 near the U-shaped frame 5, a first worm gear 513 which is rotatably arranged in the mounting box 511 and fixedly sleeved on the rotating shaft 512, a first worm 514 which passes through the mounting box 511 longitudinally and is rotatably connected to the mounting box 511, and a first knob 515 which is fixedly connected to one end of the first worm 514 and is located on the outside of the mounting box 511, the first worm 514 is meshed with the first worm gear 513, and the rotating shaft 512 is rotatably connected to the U-shaped frame 5 and the mounting box 511; when the flip grid 4 needs to be used to dry the film, the operator only needs to rotate the corresponding flip grid 4 near the side of the stand 2 The first knob 515 is set. Since the first knob 515 is fixedly connected to the first worm gear 514, and the first worm gear 514 is meshed with the first worm wheel 513 connected to the rotating shaft 512, the rotating shaft 512 can rotate with the rotation of the first knob 515. Since the rotating shaft 512 is fixedly connected to the side of the flipping grid 4 close to the vertical frame 2, the flipping grid 4 can be flipped with the rotation of the rotating shaft 512. When the operator turns the corresponding first knob 515, the corresponding flipping grid 4 can be easily flipped to a horizontal state for drying the film to be dried. When the drying is completed, the operator only needs to turn the corresponding first knob 515 in the opposite direction to easily flip the corresponding flipping grid 4 to a vertical state for easy storage. It is also convenient to easily flip the corresponding number of flipping grids 4 for drying operations according to the number of films to be dried.
