Description

Technical Field

[0001] This utility model relates to the field of tape processing technology, specifically a slitting device for BOPP tape processing. Background Technology

[0002] Adhesive tapes are classified according to their base material into BOPP tapes, cloth tapes, kraft paper tapes, masking tapes, fiber tapes, PVC tapes, PE foam tapes, etc. With the gradual progress of society, tapes are very common in daily life. There are many types of tapes, among which BOPP tape is also known as packaging tape. BOPP tape consists of BOPP film and an adhesive layer. It uses BOPP biaxially oriented polypropylene film as the base material, and pressure-sensitive adhesive emulsion is evenly coated on it after heating. The thickness of the adhesive layer is controlled between 8-28 micrometers. The adhesive is mainly formed by pressure-sensitive adhesive emulsion, and the main component is butyl acetate. The preparation method of BOPP tape is as follows: the BOPP film is first subjected to high voltage corona treatment to make the surface of the BOPP film rough. Then, the adhesive is coated on the rough surface of the BOPP film, dried into self-adhesive, and then wound and slit into BOPP tape rolls of different specifications.

[0003] For example, a slitting device for BOPP tape processing, with publication number CN220146059U, relates to the field of tape processing technology. This slitting device for BOPP tape processing includes a slitting table. A positioning structure and an adjustable slitting structure are fixedly installed on the top of the slitting table, with the positioning structure located below the adjustable slitting structure. This BOPP tape slitting device, by setting the adjustable slitting structure, utilizes a hydraulic cylinder to drive the slitting head to gradually descend via a lifting frame. Combined with limit pins, the spacing between each slitting head can be adjusted in real time according to the actual slitting width, enabling the slitting head to slit the tape according to actual needs. This allows the slitting device to meet the processing requirements of different cutting widths, significantly expanding its applicability and improving its practicality.

[0004] However, based on the working principle proposed in the aforementioned patent, the applicant believes that the slitting head in the aforementioned device is affected by the limiting rod and the limiting notch, which causes the slitting blade to be able to slit BOPP tape at a fixed spacing when slitting it. Furthermore, when producing tape rolls of different widths, the position of the slitting blade must be manually adjusted.

[0005] Therefore, a slitting device for BOPP tape processing is proposed to address the above problems. Utility Model Content

[0009] Preferably, connecting seats are fixedly installed on both sides of the assembly vertical plate, and a transmission rod is rotatably installed inside the connecting seat. A driven gear is fixedly installed at one end of the transmission rod, and a flange is fixedly installed at the other end of the transmission rod. A material roller is threadedly connected to the front of the flange.

[0010] Preferably, the surface of the material carrier roller is provided with a U-shaped groove, and a baffle is threaded to the end of the material carrier roller.

[0011] Preferably, a material-stopping roller is rotatably installed at the top of the middle part of the front side of the assembly vertical plate, and guide rollers are rotatably installed on both sides of the front side of the assembly vertical plate.

[0012] Preferably, a drive motor is fixedly installed at the bottom of the middle part of the back of the assembly vertical plate, and a drive gear is fixedly installed at the end of the output end of the drive motor. A transmission chain is meshed with the surface of the drive gear, and the transmission chain is meshed with the driven gear.

[0013] The beneficial effects of this utility model are:

[0014] 1.

[0024] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0025] This application discloses a slitting device for BOPP tape processing, including a base 1. An assembly vertical plate 2 is fixedly installed on one side of the top of the base 1. A limiting seat 3 is fixedly threadedly connected to the middle part of the top of the assembly vertical plate 2. A smooth rod 4 is fixedly installed inside the limiting seat 3. Several limiting arms 5 are movably installed on the surface of the smooth rod 4. A slitting blade 6 is fixedly installed at the bottom of the limiting arm 5. A support plate 7 is fixedly installed on the middle part of the outer side of the limiting seat 3. An adjusting motor 8 is fixedly installed on the top of the support plate 7. The output end of the adjusting motor 8 is set as a threaded rod 9. A grooved plate 10 is threadedly connected to the surface of the threaded rod 9. Several limiting grooves 11 are opened on the surface of the grooved plate 10. A first T-shaped rod 12 is fixedly installed in the inner cavity of the limiting arm 5 near the adjusting motor 8.

[0026] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 The limiting grooves 11 are inclined at a certain ratio. The first T-shaped rod 12 is movably installed inside the limiting groove 11. Through the structural design of the limiting seat 3, the light rod 4, the limiting arm 5, the slitting blade 6, the adjusting motor 8, the threaded rod 9, the groove plate 10, the limiting groove 11, and the first T-shaped rod 12, and through the cooperation between the structures, the function of automatically adjusting the slitting spacing is realized. This ensures that all slitting blades 6 move simultaneously and evenly, thereby ensuring the accuracy of slitting. At the same time, the slitting width can be freely adjusted, avoiding the drawbacks of traditional fixed-spacing slitting.

[0027] Positioning ears 13 are fixedly installed on both sides of the top of the slot plate 10 near the regulating motor 8. A second T-shaped rod 14 is fixedly installed on the top of the positioning ears 13. Limiting ears 15 are fixedly installed on both sides of the outer side of the limiting seat 3.

[0028] Reference Figure 3 and Figure 4 The second T-shaped rod 14 is movably installed inside the limiting ear 15. The second T-shaped rod 14 and the limiting ear 15 facilitate the limiting of the slot plate 10 during the lifting process, thereby ensuring the verticality of the slot plate 10 during the lifting process, and thus ensuring the accuracy of the spacing adjustment of the slitting blade 6.

[0029] Both sides of the assembly vertical plate 2 are fixedly installed with connecting seats 16. A transmission rod 17 is rotatably installed inside the connecting seat 16. A driven gear 18 is fixedly installed at one end of the transmission rod 17, and a flange 19 is fixedly installed at the other end of the transmission rod 17. A material roller 20 is threadedly connected to the front of the flange 19.

[0030] Reference Figure 1 and Figure 2The connecting seat 16 provides space for the installation of the transmission rod 17, and the transmission rod 17 can be used to cooperate with the driven gear 18 to realize the transmission function. In this way, the rotational force of the drive motor 25 can be transmitted to the material roller 20. The material roller 20 provides space for the raw materials and the materials after cutting, which facilitates the subsequent cutting of BOPP tape.

[0031] The surface of the material carrier roller 20 is provided with a U-shaped groove 21, and the end of the material carrier roller 20 is threadedly connected with a baffle 22.

[0032] Reference Figure 1 The U-shaped slot 21 provides space for key installation, which facilitates the synchronous rotation of the material cylinder, thereby achieving the purpose of feeding and winding BOPP tape. The baffle 22 helps to prevent the tape from slipping onto the surface of the material carrier roller 20 during operation.

[0033] A material-stopping roller 23 is rotatably installed on the top of the middle part of the front of the assembly vertical plate 2, and guide rollers 24 are rotatably installed on both sides of the front of the assembly vertical plate 2.

[0034] Reference Figure 1 The material support roller 23 provides space for material placement during the material transfer process and supports the BOPP tape, thus facilitating the slitting blade 6 to cut the BOPP tape. The guide roller 24 provides guidance for the BOPP tape, thereby ensuring the tension of the BOPP tape during the conveying process.

[0035] A drive motor 25 is fixedly installed at the bottom of the middle part of the back of the mounting vertical plate 2. A drive gear 26 is fixedly installed at the end of the output end of the drive motor 25. A transmission chain 27 is meshed with the surface of the drive gear 26. The transmission chain 27 is meshed with the driven gear 18.

[0036] Reference Figure 1 and Figure 2 The drive function is achieved through the drive motor 25, drive gear 26, and transmission chain 27, which ensures that the material rollers 20 on both sides rotate synchronously, thereby ensuring the smoothness of the cutting process.

[0037] Working principle: When using this device, the material carrier roller 20 carries the BOPP tape raw material cylinder and the slitting cylinder respectively. The adjusting motor 8 drives the threaded rod 9 to rotate, which in turn drives the groove plate 10 to rise and fall. The limiting groove 11 in the groove plate 10 generates a thrust on the first T-shaped rod 12, which in turn drives the limiting arm 5 to move. The slitting blade 6 moves with the limiting arm 5. When the spacing between the slitting blades 6 reaches the threshold, the drive motor 25, in conjunction with the drive gear 26, drives the transmission chain 27 to rotate. The transmission chain 27 drives the driven gears 18 on both sides to rotate, which in turn drive the material carrier roller 20 to rotate in conjunction with the transmission rod 17. As the material carrier roller 20 rotates, the BOPP tape is conveyed. During this process, the guide roller 24 provides guidance for the BOPP tape, the abutment roller 23 provides support for the BOPP tape, and the slitting blade 6 cuts the BOPP tape.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
