When in use, the rice-shaped perforated silicone sheet fits tightly with the winding clamp, so that the end face of the bandage is evenly stressed during the winding process, ensuring that the bandage is completely removed. At the same time, the rice-shaped perforated silicone sheet is soft and wear-resistant, and will not be damaged by the impact of the mechanism. It can effectively reduce the scrapping of defective coreless rolls and can also effectively improve production efficiency and quality.

Description

Technical Field

[0001] The invention relates to the technical field of medical product production equipment, in particular to a bandage unwinding fork anti-winding core pulling-out device. Background Art

[0002] Thin medical bandages may have some defective products after being rolled. First, the white bandages are contaminated and dirty, second, the bandages are poorly woven, and third, the bandages have a poor appearance when rolled, mainly including uneven roll surface, excessive diameter and other defective forms.

[0003] The weaving machine produces large rolls of bandages, each roll ranging from several thousand to tens of thousands of meters. The large rolls of bandages are placed on the winding machine and passed through the winding mechanism to be rolled into coreless rolls with a diameter ranging from 3 cm to 5 cm. They are then packaged and sterilized to complete the entire production process.

[0004] The bandage is relatively soft and the fibers are fine. It is not easy to remove it from the rolling mechanism after it is rolled. The core of the roll is easy to protrude during the peeling process, causing the roll surface to be uneven and affecting the quality. Summary of the Invention

[0005] The object of the present invention is to provide a bandage unwinding fork anti-winding core pulling-out device to solve the problems raised in the above background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A bandage unwinding fork anti-winding core pulling-out device comprises a winding chopstick mounted at one end of a rotating mechanism, a fork is provided on the outer periphery of the winding chopstick and located on one side of the rotating mechanism, a through hole is provided in the fork for the winding chopstick to pass through, and a rice-shaped open-hole silicone sheet is provided on one side of the fork and is sleeved on the outer periphery of the winding chopstick.

[0008] As a further solution of the present invention: a silicone pressure ring for fixing the rice-shaped perforated silicone sheet on the pull fork is provided on the side of the rice-shaped perforated silicone sheet away from the pull fork.

[0009] As a further solution of the present invention: the inner diameter of the silicone pressure ring is d2, 35mm≤d2≤55mm.

[0010] As a further solution of the present invention: the inner diameter of the perforation is d1, 15mm≤d1≤25mm.

[0011] As a further solution of the present invention: the distance between the fork and the rotating mechanism is L, 15mm≤L≤25mm.

[0012] Compared with existing technologies, the present invention offers the following advantages: During use, the 'M'-shaped perforated silicone sheet fits tightly against the winding chopsticks, ensuring uniform force on the bandage end during the unwinding process, ensuring complete bandage removal. Furthermore, the 'M'-shaped perforated silicone sheet is soft and wear-resistant, preventing damage from mechanical impact. This effectively reduces the scrapping of coreless rolls and significantly improves production efficiency and quality.

[0013] Other features and advantages of the present invention will be disclosed in detail in the following specific embodiments and drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figures 1 to 10 In an embodiment of the present invention, a bandage unwinding fork anti-winding core pulling-out device includes a winding chopstick 4 installed at one end of a rotating mechanism 1, and a fork 2 is provided on the outer periphery of the winding chopstick 4 and on one side of the rotating mechanism 1. It is characterized in that a through hole 203 is provided in the fork 2 for the winding chopstick 4 to pass through, and a rice-shaped open-hole silicone sheet 202 is provided on one side of the fork 2 and is sleeved on the outer periphery of the winding chopstick 4.

[0027] During use, the 'M'-shaped perforated silicone sheet 202 fits tightly against the winding chopsticks 4, ensuring uniform force on the bandage end during the unwinding process, ensuring the bandage is completely unwound. Furthermore, the 'M'-shaped perforated silicone sheet 202 is soft and wear-resistant, preventing damage from mechanical impact. This effectively reduces the chances of coreless rolls being scrapped, and can also significantly improve production efficiency and quality.

[0028] In this embodiment, a silicone pressure ring 201 is provided on the side of the rice-shaped perforated silicone sheet 202 away from the fork 2 to fix the rice-shaped perforated silicone sheet on the fork 2. The silicone pressure ring 201 can improve the stability of the installation of the rice-shaped perforated silicone sheet 202.

[0029] In this embodiment, the inner diameter of the silicone pressure ring 201 is d2, 35mm≤d2≤55mm. Specifically in this embodiment, d2 is 45mm,

[0030] Because the chopsticks deform with prolonged use, the fork and clip are prone to colliding during the unwinding process. The fork hole must be sufficiently large to prevent this. However, if the hole is too large, the inner ring of the bandage roll end face will not be stressed, leaving only the outer ring. This can cause the roll core to be pulled out or bulge during unwinding. For this reason, the inner diameter of the perforation 203 is d1, with a range of 15 mm ≤ d1 ≤ 25 mm. Specifically, in this embodiment, d1 is 20 mm. This prevents collisions between the fork and clip during unwinding and ensures uniform stress on the inner ring of the bandage roll end face, facilitating unwinding.

[0031] Because the coiling chopstick 4 has greater rigidity near the rotating mechanism 1, to prevent bending of the coiling chopstick 4 and its impact on unwinding, the spacing L between the fork 2 and the rotating mechanism 1 is set to 15 mm ≤ L ≤ 25 mm. Specifically, in this embodiment, L is 20 mm. This ensures efficient unwinding and prevents collision between the fork and the clamp during unwinding.

[0032] It is understandable that d1 can also be 15mm, 16mm, 17mm, 18mm, 19mm, 21mm, 22mm, 23mm, 24mm, 25mm, 26mm, 27mm, 28mm, 29mm, 30mm, etc.

[0033] It is understandable that d2 can also be 35mm, 36mm, 37mm, 38mm, 39mm, 40mm, 41mm, 42mm, 43mm, 44mm, 46mm, 48mm, 49mm, 50mm, 51mm, 52mm, 53mm, 54mm, 55mm, etc.

[0034] It is understandable that L can also be 15mm, 16mm, 17mm, 18mm, 19mm, 21mm, 22mm, 23mm, 24mm, 25mm, etc.

[0035] It can be understood that the gap 401 is provided in the winding clamp 4, which can effectively reduce the friction between the bandage and the winding clamp 4 and improve the efficiency and quality of unwinding.

[0036] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0037] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
