Description

Technical Field

[0001] This utility model relates to the field of roll material transfer technology, specifically to an antistatic storage and transportation turnover box for carbon fiber roll materials. Background Technology

[0002] Carbon fiber is a high-molecular fiber material with characteristics such as high lightness and low density, and it is widely used in aerospace, automotive, sporting goods, and electronics and electrical fields.

[0003] During the transfer of carbon fiber rolls through turnover boxes, static electricity may be generated due to bumps and friction inside the turnover box. Static electricity accumulates inside the box and may cause partial discharge. The instantaneous high temperature may burn the resin coating on the surface of the carbon fiber or cause the adhesive between the fibers to fail, resulting in fuzzing, delamination or even breakage of the roll edge. In addition, carbon fiber rolls are prone to collision with the box during the transfer process, which may cause scratches or wear on their surface. Utility Model Content

[0004] Based on the above-mentioned problems existing in the prior art, the purpose of this utility model embodiment is to provide a carbon fiber roll antistatic storage and transportation turnover box.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a carbon fiber roll antistatic storage and transportation turnover box, including a base plate, on which a number of positioning posts and a number of clamping parts are detachably arranged. The upper surface of the base plate and the outer surface of the positioning posts are coated with an antistatic coating. Each set of clamping parts includes a chuck movably arranged on both sides of the positioning post. The side of the chuck facing the positioning post is provided with a number of arc segments of different diameters. The side of the arc segments facing the positioning post is provided with an antistatic elastic layer. The base plate is provided with a driving part for controlling the movement of the chuck. The bottom of the base plate is provided with a number of conductive wheels.

[0006] Furthermore, the arc segment includes a large arc segment, a medium arc segment, and a small arc segment according to its diameter. The two large arc segments are located on the outermost side of the chuck, the small arc segment is located on the innermost side of the chuck, and the medium arc segment is disposed on the chuck and located between the large arc segment and the small arc segment.

[0007] Furthermore, the top surface of the base plate has a groove along its length, and support plates are provided at both ends of the groove. A screw located in the groove is rotatably arranged between the two support plates. The screw is divided into a smooth part, a forward thread section and a reverse thread section. The bottom surface of the chuck has a movable block integrally formed that extends into the groove and is threadedly connected to the screw. One of the chucks in the same group is threadedly connected to the forward thread section, and the other chuck is threadedly connected to the reverse thread section.

[0008] Furthermore, the top surface of the base plate is provided with several through slots extending downward along its width direction, and the height of the through slots is higher than the height of the screw.

[0009] Furthermore, the positioning post includes a base plate and a circular rod disposed on the base plate. The top of the circular rod is integrally formed with a frustum. The bottom of the frustum has the same diameter as the circular rod. The horizontal cross-section of the frustum gradually decreases from bottom to top. The base plate is recessed downward to form a recessed groove for accommodating the base plate. The bottom wall of the recessed groove is provided with a threaded groove. The base plate is provided with a through hole corresponding to the threaded groove.

[0010] Furthermore, the top surface of the chuck is provided with a plurality of positioning rods, and the bottom surface of the chuck is provided with positioning grooves that correspond one-to-one with the positioning rods.

[0011] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: the antistatic coating, antistatic elastic layer and conductive wheel can discharge static electricity in time, preventing static electricity accumulation from damaging the carbon fiber roll. The chuck fixes the carbon fiber roll to prevent dynamic friction between the roll and other objects from generating a large amount of static electricity. At the same time, it can also prevent the roll from scratching other items. The chuck is equipped with multiple arc segments of different diameters, which can clamp rolls of various diameters and has a wide range of applications. Attached Figure Description

[0019] The present invention will now be described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0020] Please see Figure 1-3 This utility model provides a technical solution: a carbon fiber roll antistatic storage and transportation turnover box, including a base plate 1, on which a push-pull handle (not shown in the figure) is provided. Several positioning posts 2 and several sets of clamping parts are detachably provided on the base plate 1. The upper surface of the base plate 1 and the outer surface of the positioning posts 2 are coated with an antistatic coating. Each set of clamping parts includes a chuck 3 movably disposed on both sides of the positioning post 2. The side of the chuck 3 facing the positioning post 2 is provided with multiple arc segments of different diameters. The side of the arc segments facing the positioning post 2 is provided with an antistatic elastic layer 34. The base plate 1 is provided with a driving component for controlling the movement of the chuck 3. The bottom of the base plate 1 is provided with multiple conductive wheels.

[0021] The generation of static electricity is reduced by using an antistatic coating and an antistatic elastic layer 34. The antistatic coating can be a conductive polymer coating, such as a polypyrrole coating, or conductive particles, such as carbon-based, metal-based, or metal oxides, can be added to the resin to form a conductive path and reduce surface resistance. The base plate 1 is made of polypropylene material with added polyethylene glycol derivatives. The charge can be conducted to the ground through the conductive wheel. The carbon fiber roll 5 is fixed by the chuck 3 to reduce the dynamic friction between the carbon fiber roll 5 and other objects and reduce the generation of static electricity.

[0022] The arc segments are divided into large arc segments 31, medium arc segments 32 and small arc segments 33 according to their diameter. The two large arc segments 31 are located on the outermost side of the chuck 3, the small arc segment 33 is located on the innermost side of the chuck 3, and the medium arc segment 32 is set on the chuck 3 and located between the large arc segments 31 and the small arc segment 33.

[0023] Taking the left chuck 3 as an example, the middle arc segment 32 is located inside the large arc segment 31, and the middle arc segment 32 is located on the left side of the circumference of the large arc segment 31. Therefore, when the large arc segment 31 clamps and fixes the large diameter carbon fiber roll 5, the middle arc segment 32 will not touch the large diameter carbon fiber roll 5, so as not to interfere with the clamping and fixing of the large diameter carbon fiber roll 5 by the large arc segment 31.

[0024] Similarly, the small arc segment 33 is located inside the middle arc segment 32 and on the left side of the circumference of the middle arc segment 32. Therefore, when the middle arc segment 32 clamps and fixes the medium-diameter carbon fiber roll 5, the small arc segment 33 will not touch the medium-diameter carbon fiber roll 5, so as not to interfere with the clamping and fixing of the medium-diameter carbon fiber roll 5 by the middle arc segment 32.

[0025] The top surface of the base plate 1 has a groove 11 along its length. Support plates 41 are provided at both ends of the groove 11. A screw 42 located in the groove 11 is rotatably arranged between the two support plates 41. The screw 42 is divided into a smooth part, a forward thread section and a reverse thread section. The bottom surface of the chuck 3 is integrally formed with a movable block that extends into the groove 11 and is threadedly connected to the screw 42. In the same group of chucks 3, one chuck 3 is threadedly connected to the forward thread section and the other chuck 3 is threadedly connected to the reverse thread section.

[0026] The screw 42 is driven by the motor 43. For multiple sets of chucks 3 threadedly connected to the same screw 42, the chucks 3 on the left side of each set are connected to the forward thread, and the chucks 3 on the right side of each set are connected to the reverse thread. The pitch between the forward and reverse threads is the same. The rotation of the screw 42 allows two chucks 3 in the same set to move towards or away from each other. Initially, the distance between each chuck 3 and its corresponding positioning post 2 is equal. Regardless of how the screw 42 rotates, the distance between each chuck 3 and the positioning post 2 remains equal, facilitating the simultaneous fixing of chucks of the same specifications. The carbon fiber roll 5 has an antistatic elastic layer 34 made of conductive silicone rubber or conductive thermoplastic polyurethane. By adding conductive carbon black, graphene or metal powder, it meets the antistatic requirements and has a certain degree of elasticity. When clamping the carbon fiber roll 5, it can undergo elastic deformation to increase the contact area between the layer and the carbon fiber roll 5, reduce pressure and avoid scratching and damage to the roll. It also improves fault tolerance and avoids the chuck 3 being unable to clamp the smaller diameter carbon fiber roll 5 when there are some differences in diameter among multiple carbon fiber rolls 5 of the same specification.

[0027] The top surface of the base plate 1 has several through slots 12 extending downward along its width direction. The height of the through slots 12 is higher than the height of the screw 42.

[0028] When unloading the carbon fiber roll 5, the forks of a forklift can be inserted into the through slot 12 to handle and unload the material, reducing manual labor.

[0029] The positioning post 2 includes a base plate 21 and a round rod 22 disposed on the base plate 21. The top of the round rod 22 is integrally formed with a frustum 23. The bottom of the frustum 23 has the same diameter as the round rod 22. The horizontal cross section of the frustum 23 gradually decreases from bottom to top. The base plate 1 is recessed downward to form a recessed groove 13 for accommodating the base plate 21. The bottom wall of the recessed groove 13 is provided with a threaded groove downward. The base plate 21 is provided with a through hole corresponding to the threaded groove.

[0030] The positioning post 2 is connected by bolts for easy replacement. After the bolt is screwed into the threaded groove, the top of the bolt does not exceed the recessed groove 13 to prevent the bolt from contacting the carbon fiber roll 5 and causing deformation and scratches to the carbon fiber roll 5. The positioning post 2 can be replaced according to the inner diameter of the carbon fiber roll 5. The appropriate positioning post 2 can be selected. The truncated cone 23 at the top of the positioning post 2 can play a guiding role to facilitate the placement of the carbon fiber roll 5.

[0031] The top surface of the chuck 3 is provided with several positioning rods 35, and the bottom surface of the chuck 3 is provided with positioning grooves that correspond one-to-one with the positioning rods 35.

[0032] For some wide carbon fibers, that is, carbon fiber rolls 5 that are longer in the circumferential direction, multiple chucks 3 can be stacked in the height direction by using positioning rods 35 and positioning slots to better fix the carbon fiber rolls 5.

[0033] Usage process: Pass the mandrel hole of the carbon fiber roll 5 through the positioning post 2 and place the carbon fiber roll 5 on the base plate 1. Then start the motor 43 to bring the two chucks 3 in the same group closer to each other until they squeeze the carbon fiber roll 5. Then transfer the entire device to the designated location for storage or unloading. When unloading, reverse the motor 43 to move the chucks 3 away from the carbon fiber roll 5. Then insert the forklift forks into the through slot 12 to realize the unloading.

[0034] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the scope of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
