Description

Technical Field

[0001] This utility model relates to the technical field of tape production, and in particular to a needle roller mechanism for processing tape. Background Technology

[0002] To meet the breathability or bubble-proof requirements of adhesive tapes in specific applications, it is often necessary to prepare dense micropores on their surface. In existing technologies, this is often achieved using a needle roller piercing method. This involves a rolling mechanism consisting of a needle roller and a pressure roller, which continuously rolls and pierces the tape through needles on the surface of the needle roller during tape transport. However, this existing technology has significant limitations. When producing different specifications of adhesive tape products and needing to adjust the pore density, the entire needle roller assembly must be disassembled and replaced with a new needle roller with the corresponding needle density. After replacement, the relative position and parallelism between the needle roller and the pressure roller must be recalibrated to ensure uniform piercing quality. This process is not only cumbersome and time-consuming, but also reduces equipment utilization and production flexibility, making it difficult to adapt to the rapid turnaround requirements of multi-variety, small-batch production.

[0021] Reference Figures 1 to 3 According to a first aspect of the present invention, a needle roller mechanism for processing adhesive tape includes a frame 100, a drive device 200, a needle roller 300, a pressure roller 400, and a conveying assembly. The drive device 200 is disposed on the frame 100. The needle roller 300 includes a first roller body 310 and a needle shell assembly. The needle shell assembly is detachably mounted on the outer peripheral wall of the first roller body 310. The first roller body 310 is rotatably connected to the frame 100. The pressure roller 400 is rotatably connected to the frame 100 and is used to cooperate with the needle roller 300. The conveying assembly is disposed on the frame 100. The drive device 200 is used to drive the needle roller 300 assembly, the pressure roller 400, and the conveying assembly. The conveying assembly is used to convey film material between the needle roller 300 assembly and the pressure roller 400. The needle shell assembly includes a semi-circular first shell 320 and a semi-circular second shell 330. The first shell 320 and the second shell 330 are connected to each other on the outer peripheral wall of the first roller body 310 through a connecting structure. Multiple sizes of needle housing components can be prepared for replacement. When it is necessary to change the specifications, the semi-circular first housing 320 and second housing 330 can be directly disassembled and assembled along the radial direction of the first roller body 310, so that the entire first roller body 310 does not need to be disassembled, thus maintaining the parallelism of the roller and making disassembly and assembly more convenient.

[0022] Specifically, the drive unit 200 can be a drive motor. The needle roller 300 and the pressure roller 400 are arranged parallel to each other on the frame 100. The drive unit 200 can transmit power to the needle roller 300 and the pressure roller 400 via a transmission belt and gears, enabling the needle roller 300 and the pressure roller 400 to rotate in opposite directions. The specific transmission structure is a conventional technical means and will not be described in detail here. The conveying assembly can be a feeding roller 510, a guide roller 530, and a receiving roller 520. The receiving roller 520 can be connected to the drive unit 200 for transmission. Through the above structure, the film material is conveyed between the needle roller 300 and the pressure roller 400 for the needle roller 300 to perform piercing processing. The needle roller 300 is composed of a first roller body 310 and a needle housing assembly. The first roller body 310 is rotatably connected to the frame 100 without disassembly. The outer peripheral wall of the needle housing assembly is covered with needles 350 for puncture. The shape and density of the puncture holes vary depending on the specifications required, thus allowing for the use of needle housing assemblies of different specifications. When switching specifications, the first housing 320 and the second housing 330 can be removed radially opposite to each other from the first roller body 310, requiring minimal operating space and involving few obstructing parts, facilitating disassembly. During installation, the first housing 320 and the second housing 330 of the required specifications are installed facing each other to completely enclose the outer peripheral wall of the first roller body 310. With this structure, the needle roller 300 does not require overall disassembly, maintaining its current parallelism, and the direction of needle housing assembly disassembly and assembly improves the efficiency of specification switching.

[0023] Reference Figures 2 to 3 In some embodiments of this utility model, the connecting structure includes a connector 340, a first connecting groove 321, and a second connecting groove 331. The first connecting groove 321 is disposed in the first housing 320, and the second connecting groove 331 is disposed in the second housing 330. When the first housing 320 and the second housing 330 are aligned and connected, the first connecting groove 321 and the second connecting groove 331 are connected. The connector 340 is installed in the connected first connecting groove 321 and the second connecting groove 331 by fasteners. Specifically, multiple connecting structures can be provided and spaced apart along the length of the needle roller 300 to improve the connection strength.

When the first housing 320 and the second housing 330 are mated together to form a cylindrical structure, the first connecting groove 321 and the second connecting groove 331 can be connected to each other to form a total connecting groove. The shape of the total connecting groove matches that of the connector 340, and the connector 340 can be placed into the total connecting groove. It is understood that the connector 340 can be locked to the first connecting groove 321 and the second connecting groove 331 by fastening bolts. With the above structure, the two semi-circular first housings 320 and second housings 330 can be connected to each other.

[0024] Reference Figures 2 to 3In some embodiments of this utility model, the outer wall of the connector 340 away from the needle housing assembly is designed with an arc surface structure. Specifically, the arc surface structure of the outer wall of the connector 340 can be smoothly aligned with the outer wall of the cylindrical needle housing assembly to avoid protrusions affecting processing.

The connecting holes 341 are countersunk holes, and the fasteners are countersunk screws. Specifically, during installation, the countersunk screws can be threaded through the connecting holes 341 and connected to the corresponding first threaded holes 3211 and second threaded holes 3311. The countersunk screws and countersunk holes cooperate to prevent the fasteners from protruding and to avoid affecting the needle punching process.

[0026] Reference Figures 2 to 3 In some embodiments of this utility model, the first housing 320 and the second housing 330 are provided with positioning structures, which include positioning posts 322 and positioning holes 332.

When the first housing 320 and the second housing 330 are aligned, the positioning post 322 can be inserted into the positioning hole 332. Specifically, multiple positioning structures can be provided and spaced apart along the length of the needle roller 300. When the first housing 320 and the second housing 330 are aligned, positioning can be achieved by the positioning post 322 and the positioning hole 332. After the positioning post 322 is inserted into the positioning hole 332, the first housing 320 and the second housing 330 can be pre-fixed to facilitate the locking of the connecting piece 340.

[0027] Reference Figures 2 to 3 In some embodiments of this utility model, a chamfer is provided between the protruding end face of the positioning post 322 and the outer side wall, and a chamfer is provided for the positioning hole 332. Specifically, the chamfers of the positioning hole 332 and the positioning post 322 can serve as guides to facilitate the insertion of the positioning post 322 into the positioning hole 332.
