Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of the use of lens paper, in particular to a lens paper winder. Background Art
[0002] Lens paper is a product specially equipped for lens wiping, and its function is similar to that of glasses cloth for wiping glasses. It is mainly used for wiping lenses of cameras, microscopes and other devices with high clarity requirements.
[0003] When using lens paper, the paper needs to be first rolled into a cylinder, and then torn off forcefully. The torn edge is used to wipe the lens. Since the lenses wiped with lens paper have relatively high clarity requirements, the part of the lens paper in contact with the fingers usually cannot be used to wipe the lens anymore, because the grease on the fingers will contaminate the touched lens paper, and then contaminate the wiped lens.
[0004] Constrained by the use method of lens paper, usually one piece of lens paper can only be used twice, that is, one piece of paper is torn into two sections, and the two torn edges can meet the wiping requirements. For the other parts, most of them are in contact with the fingers during the winding process, so they can no longer meet the wiping requirements. Or even if there are still some parts that have not been in contact with the fingers, they are too short to be torn off continuously. Therefore, the utilization rate of the existing lens paper is generally low. Summary of the Utility Model
[0005] To solve the above problems, that is, the problem that the utilization rate of lens paper is low due to the constraints of wiping conditions, the utility model provides a lens paper winder, which includes a sleeve and a paper winding clip inserted into the sleeve. The paper winding clip includes a top cap, and two symmetrically arranged clamping plates are fixedly connected to the bottom end of the top cap for clamping the lens paper. The cross section of the clamping plate is set as a semi-circle, and the bottom end of the clamping plate is set as a semi-conical shape; the sleeve is hollow, the bottom end of the sleeve is also set as a conical shape, and the inner diameter of the bottom end of the sleeve is smaller than the outer diameter of the bottom end of the clamping plate.
[0006] The further setting of the utility model is that the clamping plate is made of an elastic material.
[0007] The further setting of the utility model is that a top block is sleeved on the two clamping plates together. The inner diameter of the top block is larger than the diameter of the clamping plate. The top end of the top block is fixedly connected with a spring, and the spring is sleeved on the two clamping plates. The end of the spring away from the top block is fixedly connected with the top cap; the diameter of the top block is larger than the inner diameter of the sleeve.
[0008] The further setting of the utility model is that a positioning cylinder is fixedly connected to the top end of the sleeve, and a clamping edge abutted against the top block is arranged in the positioning cylinder.
[0009] A further setting of the present utility model is that: an arc-shaped guide plate is provided at the top end of the positioning cylinder.
[0010] The beneficial effects of the present utility model are as follows:
[0011] 1. By providing two clamping plates, the purpose of clamping the lens paper can be achieved. Then, by rotating the two clamping plates, the purpose of rolling the lens paper into a tube shape can be achieved. During this process, the lens paper will not come into contact with the fingers, further avoiding the purpose that the grease on the fingers will contaminate the lens paper. When the lens paper rolled by the clamping plates is inserted into the sleeve together with the clamping plates and cooperates with the sleeve, at this time, since the inner diameter of the bottom end of the sleeve is smaller than the outer diameter of the bottom end of the clamping plate, and the bottom ends of both are provided with a conical shape, so when pressing down the top cap, the clamping of the lens paper can be achieved. At this time, then use a bent-nose pliers to clamp the lens paper extending out of the sleeve and pull forcefully to achieve the purpose of tearing the lens paper. At the same time, when not pressing down the top cap, the lens paper can also be pulled outwards by using a bent-nose pliers, further achieving the purpose of using one piece of lens paper multiple times and improving the utilization rate of the lens paper.
[0012] 2. Through the cooperation of the spring and the top block, when releasing the pressing of the top cap, the paper-rolling clip can be automatically reset. Description of the Drawings

[0022] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.
[0023] The utility model provides a lens paper roll-up device, comprising a sleeve 1 and a paper roll clamp 2 inserted in the sleeve 1. The paper roll clamp 2 includes a top cap 21. Two clamping plates 22 are fixedly connected to the end surface of the top cap 21. The two clamping plates 22 are symmetrically arranged about the axis of the top cap 21. The lens paper can be clamped by the two clamping plates 22.
[0024] The cross-section of the clamping plate 22 is semicircular, and the bottom end of the clamping plate 22 is semi-conical. The flat surfaces of the two clamping plates 22 are arranged opposite each other, thereby clamping the lens film. The sleeve 1 is hollow, and the bottom end of the sleeve 1 is also conical to match the semi-conical end of the clamping plate 22. The inner diameter of the bottom end of the sleeve 1 is smaller than the outer diameter of the bottom end of the clamping plate 22, so that the bottom end of the clamping plate 22 cannot extend from the bottom end of the sleeve 1.
[0025] The clamping plates 22 are made of a hard plastic material with elasticity, that is, the two clamping plates 22 can be slightly opened to facilitate inserting the lens tissue between the two clamping plates 22 to achieve the purpose of clamping the lens tissue.
[0026] A circular top block 23 is mounted on both clamping plates 22. The inner diameter of the top block 23 is larger than the diameter of the clamping plates 22 to prevent the top block 23 from affecting the opening of the two clamping plates 22. A spring 24 is fixedly connected to the top of the top block 23. The spring 24 is mounted on the two clamping plates 22, and the end of the spring 24 facing away from the top block 23 is fixedly connected to the top cap 21. The diameter of the top block 23 is larger than the inner diameter of the sleeve 1.
[0027] When the paper roll clamp 2 is inserted into the sleeve 1, the top block 23 can be against the top end of the sleeve 1. At this time, pressing the top cap 21 can compress the spring 24 and move the clamping plate 22 downward. When the top cap 21 is released, the clamping plate 22 and the top cap 21 can be automatically reset under the action of the elastic force of the spring 24.
[0028] The top end of the sleeve 1 is fixedly connected to a positioning tube 11 , which is coaxial with the sleeve 1 . A clamping edge 111 for abutting against the top block 23 is integrated into the positioning tube 11 , that is, the diameter of the top block 23 is larger than the inner diameter of the clamping edge 111 .
[0029] An arc-shaped guide plate 112 is integrally provided at the top end of the positioning cylinder 11 , and the guide plate 112 can play a guiding role when inserting the paper roll clamp 2 .
[0030] Usage process: First, insert a thin plate between the two clamping plates 22 to slightly spread the two clamping plates 22, then insert lens paper between the two clamping plates 22, pull out the thin plate, and rotate the top cap 21 to make the paper roll holder 2 rotate, thereby rolling the lens paper into a tube shape. When rolling to the root of the lens paper book, pull hard on the paper roll holder 2 to tear the lens paper rolled into a tube shape from the lens paper book.
[0031] Secondly, insert the paper roll holder 2 with the rolled lens paper into the sleeve 1 until the top block 23 abuts against the clamping edge 111. It should be noted here that the inner diameter of the sleeve 1 is set larger than the diameter of the clamping plate 22 to meet the purpose of inserting the paper roll holder 2 with the rolled lens paper into the sleeve 1. It should also be noted that the bottom end of the clamping plate 22 is located inside the lens paper during paper rolling and is not flush with the edge of the lens paper. In this way, after inserting the paper roll holder 2 into the inside of the sleeve 1, the lens paper extending beyond the bottom end of the clamping plate 22 will extend out from the bottom end of the sleeve 1, making subsequent operations more convenient.
[0032] Finally, press the top cap 21 to compress the spring 24, and the clamping plate 22 moves towards the inside of the sleeve 1. At this time, under the action of the conical end of the sleeve 1, the two clamping plates 22 will be gradually squeezed towards each other, thereby realizing the clamping of the lens paper. At this time, use a bent-nose pliers to clamp the lens paper extending out of the sleeve 1 and pull hard in two directions to achieve the purpose of tearing the lens paper. Under the clamping action of the two clamping plates 22, the break position of the lens paper will occur at the part extending out of the sleeve 1, and then the lens can be wiped with the end of the lens paper.
[0033] After the break is wiped once, the pressure on the top cap 21 can be released to make the spring 24 drive the clamping plate 22 to automatically reset. The clamping plate 22 will be driven to move towards the top cap 21, and the clamping force of the two clamping plates 22 on the lens paper is relaxed. At this time, in cooperation with the bent-nose pliers clamping the extending part of the lens paper and pulling it outwards, the purpose of pulling the lens paper outwards can be achieved. When it is pulled out long enough, stop pulling, continue to press the top cap 21 and repeat the above steps to achieve multiple uses of a piece of lens paper, and the lens paper does not need to contact the fingers throughout the process.
[0034] In summary, by providing two clamping plates 22, the present utility model can achieve the purpose of clamping the lens paper. Then, by rotating the two clamping plates 22, the lens paper can be rolled into a tubular shape. During this process, the lens paper will not come into contact with the fingers, further avoiding the purpose of the grease on the fingers contaminating the lens paper. The lens paper rolled by the clamping plates 22 is inserted into the sleeve 1 together with the clamping plates 22 and cooperates with the sleeve 1. At this time, since the inner diameter of the bottom end of the sleeve 1 is smaller than the outer diameter of the bottom end of the clamping plates 22, and the bottom ends of both are provided in a conical shape, when pressing down the top cap 21, the clamping of the lens paper can be achieved. At this time, by using a bent-nose pliers to clamp the lens paper extending out of the sleeve 1 and pulling forcefully, the purpose of tearing the lens paper can be achieved. At the same time, when the top cap 21 is not pressed tightly, the lens paper can also be pulled outwards by using a bent-nose pliers, further achieving the purpose of using one piece of lens paper multiple times and improving the utilization rate of the lens paper. Through the cooperation of the spring 24 and the top block 23, the paper-rolling clamp 2 can be automatically reset when the pressing on the top cap 21 is released.
