Description

Technical Field

[0001] This utility model belongs to the field of packaging equipment technology, and more specifically, relates to a corner protector forming component and a roll-type cushioning corner protector packaging equipment. Background Technology

[0002] The common practice in China is to use a three-step process for finished and semi-finished steel / aluminum coils (hereinafter collectively referred to as "coils"): rust prevention, protection, and bundling. Packaging aims to provide effective protection for the product during production, transportation, storage, and final distribution. This involves rust-preventive materials, protective materials, and bundling materials. Rust-preventive materials primarily consist of VCI vapor phase rust inhibitor paper or PE film; protective materials mainly include cold-rolled steel plates (or galvanized plates, etc.), PE plastic sheets, and internal and external angle steel protective components; bundling materials primarily use steel strapping.

[0003] Because the ends of the roll material are at 90° and sometimes there are overflow edges that make some parts quite sharp, there is a high possibility of local damage to the rust-proof material during packaging. In order to prevent damage to the ends of the roll material from squeezing or collision during hoisting, a layer of soft cushioning corner protectors needs to be added between the roll material and the rust-proof material. Some use paper corner protectors, and some use plastic corner protectors.

[0004] Currently, regardless of the material used, corner protectors at this location need to be installed manually, which is inefficient. Furthermore, since the outer diameter of the roll material varies greatly (generally between 700mm and 2100mm), the length of the corner protectors cannot be determined and must be cut manually on-site as needed, resulting in material waste.

[0005] To address the aforementioned issues, a search revealed that patent application CN116812349A discloses a steel coil anti-rust corner protector, its installation equipment, and a method of use. The invention includes: a support mounted on a crane, which is mounted on a film packaging device; a bundle of steel coil anti-rust corner protectors mounted on a rotating spoke; the rotating spokes mounted on the support; a discharge track mounted on the support, from which the steel coil anti-rust corner protectors extend; multiple drive rollers, each located on the side wall of the support; and the following steps enable the replacement of the corner protectors: Step 1: The crane moves, driving the discharge track to the steel coil, ensuring the anti-rust corner protectors adhere to the coil; Step 2: The rotating spokes and multiple drive rollers rotate with the steel coil, winding the anti-rust corner protector around one end of the coil until it completes one lap; Step 3: After winding, a cutting device cuts off the anti-rust corner protector. The corner protectors in this patent extend from the discharge track, but this cannot guarantee that the softer corner protectors will fit snugly against the steel coil, causing the corner protectors to be squeezed and deviated. Summary of the Invention

[0006] 1. The problem to be solved In view of the technical problems existing in the prior art, this utility model provides a corner protector forming component and a roll material cushioning corner protector packaging equipment, which ensures that the soft corner protector can fit tightly on the edge of the steel coil and is not easily squeezed and deviated by the winding machine.

[0007] 2. Technical Solution To solve the above problems, the technical solution adopted by this utility model is as follows: The first aspect of this utility model provides a corner protector forming component, including a base, a first guide portion, and a second guide portion; the base has a flared opening for the corner protector to enter; the first guide portion extends from the constricted portion of the flared opening to the end of the base; the second guide portion is bent downward toward the first guide portion, and the lower end face of the second guide portion is lower than the lower end face of the first guide portion; through the gradual change of the bending angle of the second guide portion, the corner protector with a flat cross-section is bent to 90°; the head of the second guide portion is located at the rear end of the constricted portion of the flared opening, and the tail extends beyond the end of the base; the extended second guide portion can press the corner protector against the edge of the steel coil, effectively ensuring that the relatively soft corner protector can fit tightly against the edge of the steel coil and is not easily squeezed or deviated by the winding machine.

[0008] According to any embodiment of the first aspect of the present invention, the first guide portion includes a guide plate, a first guide rod, and a pressure rod disposed at the front end of the first guide rod. The pressure rod is disposed perpendicular to the first guide rod, and the guide plate is disposed parallel to the first guide rod, forming a channel for the corner protector to pass through.

[0009] According to any embodiment of the first aspect of the present invention, the second guide portion includes a second guide rod, the lower end face of which is lower than the plane of the guide plate.

[0010] According to any embodiment of the first aspect of the present invention, a friction block is provided at the front end of the base near the outer side of the second guide rod.

[0011] According to any embodiment of the first aspect of the present invention, the friction block is made of hard plastic or polyurethane. The friction block material has a lower hardness than steel coil, thus avoiding wear caused by contact between the metal base and the steel coil.

[0012] According to any embodiment of the first aspect of the present invention, the second guide portion is inclined downward toward the first guide portion, and the height of the inclination change is less than or equal to the length of the corner tip. This structural design ensures that the corner tip folds along the fold line, and when the height H is greater than the length of the corner tip, the corner tip cannot be folded.

The more detailed description of embodiments of the present invention below is not intended to limit the scope of the claimed invention, but is merely illustrative and does not limit the description of the features and characteristics of the invention, in order to suggest the best mode for carrying out the invention and sufficient to enable those skilled in the art to implement it. Therefore, the scope of the present invention is defined only by the appended claims.

[0019] The following detailed description and exemplary embodiments of the present invention can be better understood in conjunction with the accompanying drawings, wherein the elements and features of the present invention are identified by reference numerals.

[0020] like Figures 1 to 7 As shown, the corner protector molding assembly of this embodiment includes a base 110, a first guide portion 120, and a second guide portion 130. The base 110 has a flared opening 111 for the corner protector 140 to enter. The first guide portion 120 extends from the constricted portion 112 of the flared opening 111 to the end of the base 110. The second guide portion 130 is bent downward toward the first guide portion 120, and the lower end face of the second guide portion 130 is lower than the lower end face of the first guide portion 120. Through the gradual change of the bending angle of the second guide portion 130, the corner protector 140, which has a planar cross-section, is bent to 90°.

[0021] like Figure 5 As shown, the head of the second guide part 130 is located at the rear end of the constriction 112 of the flared mouth 111, and the tail extends beyond the end of the base 110 by a length of L. The extended second guide part 130 can press the corner protector against the edge of the steel coil, effectively ensuring that the corner protector can be tightly attached to the edge of the steel coil and is not easily squeezed or deviated by the winding machine.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, the first guide portion 120 includes a guide plate 121, a first guide rod 122, and a pressure rod 123 disposed at the front end of the first guide rod 122. The pressure rod 123 is disposed perpendicular to the first guide rod 122, and the guide plate 121 is disposed parallel to the first guide rod 122, forming a channel for the corner guard 140 to pass through.

[0023] like Figure 4As shown, the second guide portion 130 includes a second guide rod 131, the lower end face of which is lower than the plane of the guide plate 121. Specifically, the second guide portion 130 is inclined downward toward the first guide portion 120, and the height H of the inclination change is less than or equal to the length of the sharp corner of the corner protector 140. This structural design allows the sharp corner of the corner protector to fold along the fold line; when the height H is greater than the length of the sharp corner of the corner protector 140, the sharp corner cannot be folded.

[0024] exist Figure 1 In this structure, a friction block 113 is provided at the front end of the base 110 near the outer side of the second guide rod 131. Furthermore, the friction block 113 is made of hard plastic or polyurethane. The material of the friction block 113 is lower in hardness than steel coil, thus preventing wear caused by contact between the metal base and the steel coil.

[0025] Combination Figure 6 and Figure 7 As shown, this embodiment also provides a roll-to-roll cushioning corner protector packaging device, including the aforementioned corner protector forming assembly. After the steel coil 150 is in place, the front end of the corner protector forming assembly reaches above the center of the steel coil 150 and presses onto the steel coil, conveying the corner protector 140 forward to one side of the steel coil 150. At this time, the wrapping machine starts to operate and performs the wrapping work. The paper or film of the wrapping machine presses the corner protector onto the end of the steel coil. The steel coil 150 rotates, and during subsequent operation, the corner protector 140 is in a dragged state and is gradually wrapped onto the steel coil 150.

[0026] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited to this. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
