Description

Technical Field

[0001] This utility model relates to the field of pearl cotton technology, and in particular to an antistatic EPE pearl cotton processing device. Background Technology

[0002] EPE (Expanded Polyethylene) foam, also known as polyethylene foam, is a non-crosslinked closed-cell structure and an ideal substitute for traditional packaging materials. It is frequently used in the packaging of electronic products. However, to protect these products, an antistatic liquid needs to be applied to the surface of the EPE foam or added to its raw material to give it antistatic properties. This makes packaging electronic products with EPE foam safer. After adding the antistatic liquid, the foam is usually rolled up, which is typically the final step in the process. After rolling, the foam can be packaged and transported. Existing EPE processing equipment typically uses rollers to roll the foam, but the ends of the foam are often difficult to secure to the rollers, resulting in poor uniformity during winding.

[0003] For example, a Chinese patent document discloses an antistatic EPE pearl cotton processing device (publication number: CN221777138U). Although this patent uses a limiting rod to cooperate with the winding drum to clamp and limit the pearl cotton during winding, making the pearl cotton more flat during winding, the limiting plates at both ends of the limiting rod can limit the ends of the pearl cotton to prevent the pearl cotton from shifting during winding, effectively improving the regularity of the pearl cotton winding work of the device.

[0004] However, in actual winding operations, as the winding drum continues to wind the EPE foam, the roll diameter gradually increases. The limiting rod, under the pressure of the EPE foam roll, will move upward as the spring contracts. During the continuous compression process, the spring force gradually increases, and the pressure on the limiting rod continues to rise. Initially, moderate pressure can help the EPE foam to wind smoothly, but when the pressure is too high in the later stages, it will cause the EPE foam to be over-compressed. Especially for softer EPE foam, it is easy to cause surface wrinkles and internal structural deformation, affecting the appearance and protective performance of the EPE foam. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the tendency of pearl cotton to deform during winding, which affects its appearance and protective performance.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An antistatic EPE pearl cotton processing device includes a base, with a convenient disassembly and assembly mechanism on the top of the base. The convenient disassembly and assembly mechanism includes a fixing frame, the lower end of which is fixedly connected to the upper end of the base. First servo electric cylinders are fixedly installed on the inner walls of both sides of the fixing frame. The four first servo electric cylinders are divided into two groups of two and are symmetrically distributed. One end of the piston rod of each group of first servo electric cylinders is fixedly connected to a mounting plate. A servo motor is fixedly installed on one side of the mounting plate.

One end of the rotating shaft passes through the mounting plate and is fixedly connected to a drive disk. A symmetrically distributed round-headed positioning rods are fixedly connected to one side of the drive disk. An auxiliary winding mechanism is provided above the fixing frame.

[0008] Preferably, the convenient assembly and disassembly mechanism further includes a winding drum, on the outside of which is fixedly fitted with symmetrically distributed limiting discs, and on one side of the limiting discs are symmetrically distributed positioning slots.

A second magnet is fixedly connected to one side of the arc-shaped clamping plate, and a pull groove is formed on the outer side of the arc-shaped clamping plate.

[0011] Preferably, the auxiliary winding mechanism includes a second servo electric cylinder, one end of the piston rod of the second servo electric cylinder passing through the fixing frame and fixedly mounted with a pressure sensor.

[0012] Preferably, a pressure regulating plate is fixedly connected to the lower end of the pressure sensor, and symmetrically distributed guide rods are slidably sleeved on the inner wall of the pressure regulating plate.

[0013] Preferably, the upper ends of both guide rods extend through and above the fixing frame, and the lower ends of both guide rods are fixedly connected to mounting bases, with symmetrically distributed support springs fixedly connected to the upper ends of the mounting bases.

[0014] Preferably, one end of each of the two support springs is fixedly connected to the lower end of the pressure regulating plate, and pressure rollers are rotatably connected to the inner walls of both sides of the mounting base via bearings.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] In this invention, the first servo electric cylinder drives the round-headed positioning rod to accurately insert into the receiving drum through the convenient assembly and disassembly mechanism, realizing the quick assembly and disassembly of the receiving drum and improving the continuity of production. The first magnet and the second magnet clamp the end of the pearl cotton, which is convenient for initial winding.

[0027] Example

[0028] like Figures 1-5 As shown, this utility model provides a technical solution: an antistatic EPE pearl cotton processing device, including a base 1. The device solves the problems of easy deformation of pearl cotton and difficulty in disassembling and assembling the winding drum in traditional winding by setting a convenient disassembly and assembly mechanism on the top of the base 1 in coordination with the auxiliary winding mechanism, thereby realizing efficient winding of antistatic pearl cotton and adapting to the needs of continuous production.

[0029] It should be noted that the electrical equipment involved, such as the servo motor 23, the first servo electric cylinder 21, the second servo electric cylinder 3, and the pressure sensor 31, are all existing mature technologies, so they will not be described in detail.

[0030] The mounting bracket 2 provides a stable mounting base for the first servo electric cylinder 21 and the mounting plate 22, ensuring that the driving force of the electric cylinder can be accurately transmitted. The first servo electric cylinder 21 can precisely control the extension and retraction of the piston rod, drive the mounting plate 22 to move, and realize the rapid docking and separation of the drive disc 24 and the take-up drum 26. The servo motor 23 drives the drive disc 24 to rotate through the rotating shaft 215, thereby synchronously driving the take-up drum 26 to rotate.

[0031] The round-headed positioning rod 25 on the drive plate 24 effectively reduces insertion resistance when inserted into the positioning slot 28 of the take-up drum 26, facilitating quick alignment and insertion. This significantly shortens the installation and disassembly time of the take-up drum 26, allowing for replacement in a short time and improving production continuity and efficiency. Compared to traditional manual installation and disassembly, this rapid assembly and disassembly method significantly improves efficiency, effectively reducing equipment downtime and meeting the needs of large-scale continuous production.

[0032] The clamping groove 29 on the outside of the winding drum 26 provides a space for the end of the pearl cotton. The first magnet 210 and the second magnet 213 cooperate with each other to achieve a firm clamping of the end of the pearl cotton through magnetic attraction.

[0033] During operation, the arc-shaped clamping plate 212 is pulled by the pull groove 214, so that the second magnet 213 is close to the first magnet 210. The magnetic attraction force is used to clamp the end of the pearl cotton. This clamping method is simple and quick to operate, and can ensure that the end of the pearl cotton is stably fixed in the initial stage of winding. It avoids the problems of weak fixation and residual glue residue that may occur with traditional fixing tape, and ensures the surface quality of the pearl cotton. It is especially suitable for antistatic pearl cotton winding with high requirements for surface cleanliness.

[0034] The dynamic pressure adjustment system, consisting of the second servo electric cylinder 3 and the pressure sensor 31, can monitor and adjust the pressure during the winding process in real time. During the winding process of pearl cotton, the pressure of the pressure roller 36 on the pearl cotton will change as the winding diameter changes.

[0035] Pressure sensor 31 can accurately sense pressure changes and feed the signal back to the control system. The second servo electric cylinder 3 automatically extends and retracts according to the feedback signal, adjusting the height of the pressure regulating plate 32, thereby changing the pressure of the pressure roller 36 on the pearl cotton, so that the pressure roller 36 always presses the pearl cotton with appropriate pressure.

[0036] The guide rod 33 plays a guiding and stabilizing role during the lifting and lowering of the pressure regulating plate 32, ensuring that the pressure regulating plate 32 moves smoothly and avoiding deviation and shaking, thus ensuring the accuracy and stability of pressure adjustment.

[0037] This dynamic pressure adjustment mechanism effectively solves the problem of EPE foam being squeezed and deformed later in the traditional single-spring pressure adjustment method due to continuous spring pressure. It keeps the pressure fluctuation within a very small range during the winding process, ensuring the flatness of the EPE foam winding, reducing wrinkles and offset, and significantly improving the winding quality of EPE foam.

[0038] The pressure roller 36 on the mounting base 34 is rotatably connected by a bearing, and can rotate synchronously with the pearl cotton during the pearl cotton winding process, which reduces the friction between the pressure roller 36 and the pearl cotton and avoids damage to the surface of the pearl cotton due to excessive friction.

[0039] The support spring 35 can buffer and assist in pressure adjustment when the pressure is adjusted by the pressure adjusting plate 32, further stabilizing the pressure. On the other hand, it can adapt to minor changes in the winding process of the pearl cotton, such as slight fluctuations in the thickness of the pearl cotton, ensuring that the pressure between the pressure roller 36 and the pearl cotton is always matched, thereby ensuring that the pearl cotton remains flat during the winding process and improving the quality and consistency of the wound product.

[0040] The working process of this utility model:

[0041] Step 1: Align the positioning slot 28 of the take-up drum 26 with the round-headed positioning rod 25 of the drive disk 24, start the first servo electric cylinder 21, the piston rod pushes the mounting plate 22 to move, the round-headed positioning rod 25 is inserted into the positioning slot 28, and the installation of the take-up drum 26 is completed. Insert the pearl cotton end into the clamping groove 29, and pull the arc-shaped clamping plate 212 to move through the pull groove 214, which drives the second magnet 213 to approach the first magnet 210, and clamps the pearl cotton end through magnetic attraction.

[0042] Step 2: Start the servo motor 23. The rotating shaft 215 drives the drive disk 24 and the take-up drum 26 to rotate synchronously. At the same time, start the second servo electric cylinder 3. The piston rod pushes the pressure regulating plate 32 down. The pressure roller 36 contacts the surface of the pearl cotton. The pressure sensor 31 monitors the pressure in real time. If the pressure is abnormal, such as pressure fluctuation caused by changes in the winding diameter, the second servo electric cylinder 3 automatically extends and retracts to adjust the height of the pressure regulating plate 32. The guide rod 33 ensures stability, so that the pressure roller 36 always presses the pearl cotton with the appropriate pressure, ensuring flat winding and avoiding wrinkles and deviation. After winding is completed, the first servo electric cylinder 21 retracts, the round-headed positioning rod 25 disengages from the positioning slot 28, and the take-up drum 26 is removed.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
