Description

Technical Field

[0001] The utility model relates to the technical field of automobile wiring harness electrical tape production equipment, in particular to a material guide roller device for automobile wiring harness electrical tape. Background Art

[0002] Automotive wiring harness electrical tape is a material widely used in automotive wiring harness and other fields. Its production process is relatively complicated and requires multiple steps to complete. The production process of automotive wiring harness electrical tape includes: raw material preparation (polyvinyl chloride (PVC)) - batching and mixing - melt extrusion - calendering and cooling - pulling and winding - surface treatment.

[0003] In the calendering process, the automotive wiring harness electrical tape needs to be fed into the calendering roller for calendering. The molten automotive wiring harness electrical tape enters the surface of the calendering roller and rotates with the calendering roller. Since the molten automotive wiring harness electrical tape covers the entire surface of the calendering roller and is still in the calendering state, the automotive wiring harness electrical tape at the edges of the calendering roller is easily detached and thrown out during the rotation of the calendering roller surface, resulting in waste of the automotive wiring harness electrical tape. In response to this, some existing automotive wiring harness electrical tape manufacturers have taken the following countermeasures: a collection tank for collecting scattered automotive wiring harness electrical tape is set under the calendering roller, and the automotive wiring harness electrical tape scattered in the collection tank is recycled and reused at regular intervals. Although this treatment method can avoid the waste of automotive wiring harness electrical tape, it does not avoid the problem of the automotive wiring harness electrical tape scattering outward when the calender roller surface rotates. Instead, the scattered automotive wiring harness electrical tape is collected to avoid the waste problem. Later, the automotive wiring harness electrical tape still needs to be manually recycled, the degree of automation is low, and there is a defect of increasing the workload of workers.

DETAILED DESCRIPTION

[0024] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] See attached Figure 1 and attached Figure 3 As shown, the present embodiment provides a material guide roller device 100 for automotive wiring harness electrical tape, which includes a pair of bases 10, a calendering roller 20 and a material guide roller mechanism 30 respectively arranged on the pair of bases 10, the calendering roller 20 is horizontally arranged between the bottom ends of the pair of bases 10, and the two ends of the calendering roller 20 are respectively rotatably connected with the base 10, the material guide roller mechanism 30 is arranged at the upper position of the base 10, and the pair of material guide roller mechanisms 30 are respectively matched with the two ends of the calendering roller 20, and are used for guiding the automotive wiring harness electrical tape 200 located at the two ends of the outer surface of the calendering roller 20, so that the automotive wiring harness electrical tape 200 at the edge positions of the two ends of the calendering roller 20 is close to the center of the calendering roller 20 to avoid being thrown out and scattered, resulting in waste.

[0026] Refer to the attached Figure 1 , Attachment Figure 3 And attached Figure 6 As shown, each guide roller mechanism 30 includes a guide roller 31, a locking assembly 35 and a mounting frame 32. The mounting frame 32 is fixedly mounted at the top of the base 10. The guide roller 31 is vertically arranged and arranged adjacent to the outer end of the calendering roller 20. The upper end of the guide roller 31 passes through the mounting frame 32 and is rotatably mounted on the mounting frame 32 through a bearing. The upper end of the guide roller 31 is clamped and mounted on the mounting frame 32 through the locking assembly 35. The upper end of the guide roller 31 is rotatably connected with the locking assembly 35, and the bottom end of the guide roller 31 is in rolling contact with the upper surface of the calendering roller 20. In some embodiments, the material guide roller 31 includes a cylindrical portion 311 at the upper end and a conical portion 312 at the lower end with an outer diameter gradually increasing from bottom to top. The setting of the conical portion 312 can better guide the automotive wiring harness electrical tape 200 onto the outer surface of the cylindrical portion 311, thereby realizing the material guiding processing of the automotive wiring harness electrical tape 200.

[0027] Refer to the attached Figure 2 As shown, when the calendering roller 20 rotates, the automotive wiring harness electrical tape 200 located on the outer surface of the calendering roller 20 rotates along with the calendering roller 20. At this time, the automotive wiring harness electrical tape 200 near the edge positions of the calendering roller 20 at both ends will be guided by the guide rollers 31 arranged at both ends of the calendering roller 20, respectively. The guide rollers 31 apply a force to the automotive wiring harness electrical tape 200 in contact with it toward the center direction of the calendering roller 20, so that the automotive wiring harness electrical tape 200 moves toward the center direction of the calendering roller 20, thereby avoiding the material waste caused by the automotive wiring harness electrical tape 200 located at the two ends of the calendering roller 20 scattering outward during the rotation of the calendering roller 20.

[0028] Combined with reference to Figure 1 , Attachment Figure 3 And attached Figure 6 As shown, in order to make the guide roller 31 applicable to more different automotive wiring harness electrical tape production occasions and have better versatility, the automotive wiring harness electrical tape guide roller mechanism 30 also includes an axial adjustment component 34 and a lateral adjustment component 33. One end of the lateral adjustment component 33 is connected to the mounting frame 32, which is used to adjust the horizontal lateral movement of the guide roller 31 located on the mounting frame 32 relative to the calendering roller 20. The axial adjustment component 34 is connected to the other end of the lateral adjustment component 33, which is used to adjust the axial reciprocating movement of the lateral adjustment component 33 along the calendering roller 20.

[0029] Specifically, the lateral adjustment assembly 33 includes an "L"-shaped connecting frame 331 and a locking screw 333. One end of the connecting frame 331 is fixedly connected to the axial adjustment assembly 34. The other end of the connecting frame 331 is provided with a waist-shaped hole 332 arranged horizontally in the transverse direction. The mounting frame 32 is fixedly installed in the waist-shaped hole 332 by the locking screw 333. The axial adjustment assembly 34 includes a motor 341, a screw rod 342, a screw rod nut 343 and a connecting seat 344. The motor 341 is fixedly installed on the base 10. The motor 341 is connected to the screw rod 342. The screw rod nut 343 is installed on the screw rod 342. One end of the connecting seat 344 is fixedly connected to the screw rod nut 343. The other end of the connecting seat 344 is fixedly connected to one end of the connecting frame 331.

[0030] When it is necessary to adjust the lateral position of the guide roller 31, that is, when it is necessary to adjust the front and rear position of the guide roller 31 on the upper surface of the calendering roller 20, the operator can first loosen the locking screw 333, and then move the mounting frame 32 laterally forward or backward to the installation position in the waist-shaped hole 332 on the connecting frame 331. When it moves to a suitable adjustment position, tighten the locking screw 333 to fix the mounting frame 32 on the connecting frame 331, thereby completing the front and rear position adjustment of the guide roller 31 on the calendering roller 20.

[0031] When the installation height of the guide roller 31 needs to be adjusted, the operator controls the motor 341 to rotate forward or reverse. The motor 341 in the rotating state drives the screw rod 342 to rotate synchronously. The screw rod 342 drives the screw nut 343 thereon to move linearly. The screw nut 343 in the linear movement state drives the connecting seat 344 to move linearly synchronously. The connecting seat 344 in the linear movement state drives the connecting frame 331 to move. The connecting frame 331 drives the mounting frame 32 to move linearly, thereby realizing the axial position adjustment of the guide roller 31 on the calendering roller 20.

[0032] Refer to the attached Figure 4 and attached Figure 5 As shown, the locking assembly 35 is installed at the top of the guide roller 31. Its function is to lock the guide roller 31 to prevent the guide roller 31 from detaching from the mounting bracket 32, and at the same time, it is also necessary to ensure the installation of the guide roller 31 in the locking assembly 35 and the horizontal rotation of the guide roller 31 in the locking assembly 35.

[0033] In this regard, the locking assembly 35 in this embodiment includes a locking ring 351 and a bolt 353. The locking ring 351 is provided with a notch 352. The two sides of the notch 352 are respectively provided with threaded holes threadedly connected to the bolt 353. The top end of the guide roller 31 is clamped and rotatably installed in the inner cavity of the locking ring 351. Specifically, a plurality of elastic beads 354 are arranged at intervals along the circumferential direction on the inner wall of the locking ring 351, and a groove 313 is arranged on the circumferential direction on the outer wall circumference of the top end of the guide roller 31 to be clamped and matched with the elastic beads 354.

[0034] In this way, when the guide roller 31 is installed in the locking assembly 35, the bolts 353 on both sides of the notch 352 of the locking ring 351 are first loosened to enlarge the inner hole size of the locking ring 351 so that the loosened locking ring 351 can be directly mounted on the top outer peripheral surface of the guide roller 31. When the loosened locking ring 351 is mounted on the upper outer peripheral surface of the guide roller 31, the elastic beads 354 on the inner wall of the locking ring 351 correspond exactly to the grooves 313 on the upper outer wall of the guide roller 31. After the elastic clamping beads 354 are docked with the groove 313, tighten the bolts 353, so that the locking ring 351 can use the elastic clamping beads 354 on the inner wall to clamp with the elastic clamping beads 354 on the outer wall around the top of the guide roller 31, and the locking ring 351 is set at the top of the mounting frame 32, so that the guide roller 31 will not slide downward from the mounting frame 32, and the elastic clamping beads 354 and the groove 313 can form a rolling connection, which ensures the normal horizontal rotation of the guide roller 31.
