Description

Technical Field

[0001] This utility model belongs to the technical field of fabric spreading machine, and specifically relates to an antistatic device for fabric spreading machines. Background Technology

[0002] A fabric spreading machine is a type of machine that emerged in the early 1990s for producing fabric. Because flexible fabrics are mostly produced and transported in rolls, an important process at the user's factory is to transform the rolls into multi-layered flat surfaces for easy cutting. Automated production equipment such as automatic fabric spreading machines and automatic fabric laying machines have emerged to address this need. However, existing fabric spreading machines are prone to generating static electricity during fabric production, and current devices typically lack static elimination devices, making it difficult to remove static electricity during continuous production.

[0003] For example, in the Chinese utility model publication CN213186660U entitled "Antistatic Device for Fabric Spreading Machine," a bracket is included. Side plates are fixedly mounted on the surface of the bracket, and a middle plate is provided on the outer surface of one end of each side plate. Guide rails are bolted to one end of both sides of the bracket. A groove is formed on the upper surface of the guide rail, and the groove is connected to a slide block via a roller. An air nozzle is connected to one outer surface of the slide block, and an electrostatic absorber is provided on the upper surface of the slide block. This prior art, through the electrostatic absorber, can provide a long-term, stable, and automatic antistatic effect during the fabric spreading process, reducing the harm caused by static electricity. Combined with the rolling action of the roller, it improves the efficiency of static electricity absorption. However, the roller's surface material is prone to aging after long-term operation, requiring roller replacement. Therefore, to reduce downtime, an antistatic device for fabric spreading machines is needed. Utility Model Content

[0004] The purpose of this utility model is to provide a simple and reasonably designed static elimination device for a fabric spreading machine in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] An antistatic device for a fabric spreading machine includes a fabric spreading machine. The bottom of the fabric spreading machine is provided with multiple fixed plates. The outer side of the multiple fixed plates is provided with mounting blocks. The outer side of the mounting blocks is provided with multiple multi-angle adjustment components. One side of each of the multiple multi-angle adjustment components is provided with a fixed component. The outer side of two of the fixed components is provided with an upper antistatic roller, and the outer side of the other two fixed components is provided with a lower antistatic roller.

[0007] As a further optimization of this utility model, the multi-angle adjustment component includes a bolt with a thread passing through the inside of the mounting block, a limit plate provided at one end of the bolt, and a nut threadedly connected to one end of the bolt, with one side of the nut contacting one side of the limit plate.

[0008] As a further optimization of this utility model, the limiting plate has a sliding groove inside, and the bolt slides through the sliding groove of the limiting plate.

[0009] As a further optimization of this utility model, the fixing component includes multiple fixing blocks disposed outside the limiting plate, each of the multiple fixing blocks having a limiting rod fixedly connected inside, and each of the multiple limiting rods having a mounting bracket on its outside, with a threaded rod rotatably connected to the top of the mounting bracket at one end.

[0010] As a further optimization of this utility model, a limiting groove is provided at the upper end of the mounting bracket, and the two ends of one of the limiting rods are slidably connected in the limiting groove provided in the mounting bracket.

[0011] As a further optimization of this utility model, the two ends of the upper and lower static elimination rollers are in contact with the inner side of the mounting frame, respectively.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This utility model allows the limiting rod to slide within the limiting groove by rotating the threaded rod, thereby moving the fixed block upward. By repeating this operation, the upper and lower antistatic rollers can be removed by slightly tilting them. The upper and lower antistatic rollers can be replaced by performing the opposite steps, which shortens downtime, requires no complicated tools or professional operation, and can be completed quickly, reducing equipment downtime, ensuring continuous fabric spreading, and improving overall production efficiency.

[0014] 2. This utility model separates the bolt and nut by rotating the bolt, moves the limiting plate, and moves the sliding groove of the limiting plate on the bolt. After reaching the designated position, the bolt and nut are tightened to fix the limiting plate, thereby completing the position adjustment of the upper and lower antistatic rollers. This improves the adaptability to fabrics of different thicknesses, ensures precise contact between the rollers and the fabric, avoids excessive stretching of thin fabrics and insufficient contact of thick fabrics, and ensures stable antistatic effect.

[0020] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] Example 1

[0022] like Figure 1 , Figure 2 As shown, an antistatic device for a fabric spreading machine includes a fabric spreading machine 1. Two fixing plates 2 are provided at the bottom of the fabric spreading machine 1. The fixing plates 2 are used to provide a mounting base for the mounting block 3. The mounting block 3 is provided on the outer side of the two fixing plates 2. The mounting block 3 provides a mounting base for the multi-angle adjustment component 6, ensuring that the multi-angle adjustment component 6 can be stably adjusted.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the mounting block 3 is externally equipped with four multi-angle adjustment components 6. These components allow for precise adjustment of the positions of the upper antistatic roller 4 and the lower antistatic roller 5. Each component includes a bolt 601, which serves as the connector. The external thread of the bolt 601 penetrates the interior of the mounting block 3, ensuring stable fixation. One end of the bolt 601 has a limiting plate 602 for subsequent component installation. Adjusting the limiting plate 602 allows for multi-angle adjustment of the subsequent components. The bolt 601 is connected by a nut 603, which, together with the nut 603, can fix the limiting plate 602 in a designated position, thus fixing and loosening the limiting plate 602 and preventing it from moving during equipment operation. One side of the nut 603 contacts one side of the limiting plate 602, and the tightening force of the nut 603 firmly fixes the limiting plate 602, ensuring its stability. The limiting plate 602 has a sliding groove inside, which provides space for the bolt 601 to slide. The bolt 601 slides through the sliding groove in the limiting plate 602, allowing the limiting plate 602 to move on the bolt 601 to adjust its position.

[0024] like Figure 1 , Figure 2As shown, each of the multiple multi-angle adjustment components 6 has a fixing component 7 on one side. The fixing component 7 is used to fix the antistatic component and ensure that it will not shift during operation. Two of the fixing components 7 have upper antistatic rollers 4 on their exterior, which are used to perform the first antistatic removal on the fabric. The other two fixing components 7 have lower antistatic rollers 5 on their exterior, which are used to perform a second antistatic removal on the fabric. The fixing component 7 includes eight fixing blocks 701, which can clamp the upper antistatic rollers 4 and the lower antistatic rollers 5. To prevent them from falling off, four fixing blocks 701 are externally fixedly connected to the outside of the limiting plate 602, so that the movement of the limiting plate 602 can drive the fixing blocks 701 to move, thereby adjusting the positions of the upper antistatic roller 4 and the lower antistatic roller 5. Each of the eight fixing blocks 701 is internally fixedly connected to a limiting rod 702. Four of the limiting rods 702 can restrict the movement direction of the fixing blocks 701, ensuring that the fixing blocks 701 can only move in a specific direction. The other four limiting rods 702 are used to fix the remaining four fixing blocks 701. Each limiting rod 702 is externally equipped with a mounting bracket 703. The mounting bracket 703 provides a mounting platform for other components of the fixing assembly 7, and also provides support for the upper antistatic roller 4 and the lower antistatic roller 5. A threaded rod 704 is threaded through the top of the mounting bracket 703. The rotation of the threaded rod 704 can drive four fixing blocks 701 to move up and down, realizing the separation and fixation of the fixing blocks 701 from the antistatic roller. One end of the threaded rod 704 is rotatably connected to the top of the fixing block 701, so that the rotation of the threaded rod 704 can be directly transmitted to the top of the fixing block 701. The fixed block 701 moves, and the upper end of the mounting frame 703 has a limit groove to ensure the stability of the movement of the limit rod 702. The two ends of one of the limit rods 702 are slidably connected in the limit groove of the mounting frame 703, so that the limit rod 702 can slide along the limit groove, thereby driving the fixed block 701 to move. The two ends of the upper antistatic roller 4 are in contact with the inner side of the mounting frame 703 to prevent it from shaking during operation. The two ends of the lower antistatic roller 5 are in contact with the inner side of the mounting frame 703 to ensure its working stability.

[0025] It should be noted that when using this type of antistatic device for a fabric spreading machine, if it is necessary to replace the upper antistatic roller 4 and the lower antistatic roller 5, first rotate the threaded rod 704, then slide the limiting rod 702 in the limiting groove, causing the fixing block 701 to move upward. Repeat the above operation until the fixing block 701 moves upward and separates from the upper and lower antistatic rollers 4 and 5. Then, tilt the upper and lower antistatic rollers 4 and 5 slightly and remove them. Conversely, repeat the above operation to replace the upper and lower antistatic rollers 5. After replacing the upper and lower antistatic rollers 4 and 5, when adjusting the contact gap between the upper and lower antistatic rollers 4 and 5 and the fabric, rotate bolt 601 to separate bolt 601 from nut 603. Then move the limiting plate 602 so that the sliding groove of the limiting plate 602 moves on bolt 601. After reaching the designated position, tighten bolt 601 and nut 603 to fix the limiting plate 602, thereby completing the position adjustment of the upper and lower antistatic rollers 4 and 5.

[0026] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
