Description

Technical Field

[0001] The present invention relates to the field of plastic film production, and particularly relates to a storage rack for plastic film rolls. Background Art

[0002] Plastic films are wound into cylindrical plastic film rolls on a production line, and the plastic films are stored in the form of film coils; the existing storage method generally directly stacks the film coils in the corner of the workshop. When the film coils are taken and placed, they are prone to rolling and collapsing, which is not conducive to safety production control.

[0003] Therefore, there is a storage rack for plastic film rolls with the patent number CN215753871U to solve the above problems. However, the device has the following defects in use. For example, by moving the distance between two groups of support plates on the base, the two groups of arc-shaped bosses on the two groups of support plates are used to support and fix the plastic film roll. However, when adjusting the two groups of support plates, it will drive multiple groups of arc-shaped bosses to move together, resulting in the same distance between the corresponding arc-shaped bosses on the two groups of support plates, so that the device can ultimately only store plastic film rolls of one length. When it is necessary to store plastic film rolls of multiple lengths, the device obviously cannot meet the usage requirements. Summary of the Invention

[0004] The purpose of the present invention is to provide a storage rack for plastic film rolls.

[0005] The technical problems of the present invention are mainly solved by the following technical solutions:

[0019] The technical solutions of the present invention will be further specifically described below through embodiments in conjunction with the drawings.

[0020] A storage rack for plastic film rolls, comprising a base 1, on both sides of the top of the base 1, vertical plates 2 are fixed, and a reinforcing rib plate is welded at the connection between the base 1 and the vertical plates 2;

[0021] On two groups of vertical plates 2, a plurality of fixing mechanisms 3 are correspondingly arranged, and a plurality of fixing mechanisms 3 on the same side are arranged side by side up and down on the side wall of the vertical plate 2. The fixing mechanism 3 includes a screw hole I31 opened on the vertical plate 2. A cylinder 32 is screwed in the screw hole I31. At the bottom of one end of the cylinder 32, an arc-shaped support plate 33 for supporting the end of the plastic film roll 8 is provided. An axial sliding cavity 34 is arranged in the cylinder 32. At both ends of the sliding cavity 34, a screw hole II35 and a through hole 36 communicating with the outside of the cylinder 32 are respectively arranged. The through hole 36 is arranged on the same side as the support plate 33. A limiting rod 37 is arranged on the outside of the cylinder 32 and sequentially passes through the corresponding screw hole II35 and the sliding cavity 34. One end of the limiting rod 37 is located in the through hole 36, and a thread 38 screwed with the screw hole II35 is arranged on the outer wall of the limiting rod 37 in the screw hole II35. A convex block 39 arranged on the same side as the through hole 36 is also arranged on the limiting rod 37 in the sliding cavity 34. A spring 310 is sleeved on the limiting rod 37 between the convex block 39 and the screw hole II35.

[0022] As Figure 1 、 2 As shown in FIGS. 3 and 4, a circular tube 4 sleeved on the cylinder 32 is arranged on the back of the vertical plate 2. The cylinder 32 is fixedly screwed with the circular tube 4, and the circular tube 4 and the support plate 33 are located on both sides of the vertical plate 2. By increasing the screwed area between the circular tube 4 and the cylinder 32, the stability in the horizontal state is improved.

[0023] As Figure 3 shown, a pull ring 5 is arranged at the end of the limiting rod 37 on the outside of the cylinder 32. The distance between the pull ring 5 and the cylinder 32 is greater than the length of the limiting rod 37 between the convex block 39 and the through hole 36, and the length of the limiting rod 37 between the convex block 39 and the through hole 36 is greater than the length of the through hole 36. After the limiting rod 37 is rotated to separate the thread 38 from the screw hole II35, the thread 38 slides into the sliding cavity 34. At this time, the spring 310 can be stretched to push the convex block 39 to drive the end of the limiting rod 37 to slide outwards from the through hole 36, and then insert into the center of the plastic film roll 8 to play a role in positioning and fixing it.

[0024] As Figure 3 、 4As shown in the figure, a support 6 for supporting the bottom end of the cylinder 32 is provided on the vertical plate 2 on the same side as the pallet 33. An arc-shaped groove 7 that buckles on the bottom end of the cylinder 32 is provided at the top end of the support 6, and the length of the support 6 is not greater than the length of the pallet 33. When the cylinder 32 is rotated, whether the end of the cylinder 32 or the end of the pallet 33 is located in the arc-shaped groove 7, the support 6 can play a role in supporting and fixing it at this time. While improving the stability of the fixing mechanism 3, it can also play a role in supporting and fixing the plastic film roll 8 on the fixing mechanism 3.

[0025] In this embodiment, the pallet 33, the cylinder 32 and the limiting rod 37 are coaxially arranged.

[0026] The usage method of the present invention: Adjust the distance between the two fixing mechanisms 3 on the same horizontal plane on the two vertical plates 2 according to the length of the plastic film roll 8. The specific steps are as follows: Rotate the cylinder 32 so that it rotates in the circular tube 4 and the screw hole I 31, and then drive the corresponding pallet 33 to displace, and finally make the opening of the pallet 33 face upward, so as to adjust the distance between the two pallets 33 to meet the usage requirements. The plastic film roll 8 is placed between the two vertical plates 2, and the end of the plastic film roll 8 is stuck into the corresponding pallet 33. At this time, the cylinder 32 abuts against the end of the plastic film roll 8 in the pallet 33 to prevent it from moving left and right.

[0027] Then rotate the limiting rod 37 to separate the thread 38 from the screw hole II 35. The thread 38 slides into the sliding cavity 34. At this time, the spring 310 expands and can push the convex block 39 to drive the end of the limiting rod 37 to slide outwards from the through hole 36, and then insert it into the center of the plastic film roll 8 to play a role in positioning and fixing it, so as to achieve the purpose of preventing the plastic film roll 8 from sliding out of the pallet 33. The present invention can separately adjust the distance between the two fixing mechanisms 3 on any horizontal plane to meet the usage requirements, so that the device can be used to store plastic film rolls 8 of various lengths at the same time, and thus effectively improve its application range. When removing the plastic film roll 8, just pull the limiting rod 37 outwards so that its end slides out of the plastic film roll 8 and flows into the through hole 36. At this time, the moving limiting rod 37 compresses the spring 310 through the convex block 39. When the thread on the limiting rod 37 contacts the screw hole II 35, rotate the limiting rod 37 to drive the thread 38 to be screwed and fixed with the screw hole II 35, preventing the spring 310 from expanding and pushing the convex block 39 to drive the limiting rod 37 to insert into the opening of the plastic film roll 8, so as to facilitate people to subsequently remove the plastic film roll 8 from the fixing mechanism 3 calmly.

[0028] The above has described the present invention in detail, but the content described is only the preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equal changes and improvements made according to the scope of application of the present invention should still fall within the scope covered by the patent of the present invention.
