Description

Technical Field

[0001] The invention relates to the technical field of heat shrink tube production, and in particular to a feeding jig applied to heat shrink tubes. Background Art

[0002] Heat shrink tubing is a special deformable heat shrink tubing, generally produced and processed with polyolefin materials. The outer tubing made of polyolefin materials has the characteristics of insulation, corrosion resistance, and wear resistance. During the processing of heat shrink tubing, a jig is required, which is mainly used as a tool to assist in controlling position or movement (or both) to assist in feeding and subsequent cutting processes.

[0003] During use of the existing heat shrink tube feeding jig, the tube wall of the heat shrink tube is in direct contact with the inner wall of the tube groove. The friction between the tube wall of the heat shrink tube and the tube groove will cause loss of the outer wall of the heat shrink tube, and some heat will be generated during the friction process. After accumulation, this part of heat will cause the temperature of the inner wall of the tube groove to rise, which may cause the deformation of the heat shrink tube. Summary of the invention

[0021] The present invention provides a feeding jig applied to heat shrink tubes, which has the following beneficial effects:.

[0022] 1. The feeding jig used for the heat shrink tube is provided with air holes and air channels to pass the air injected by the air injection tube into the cylindrical cavity composed of the first tube groove and the second tube groove. The friction between the heat shrink tube and the inner wall of the first tube groove and the second tube groove when passing through is reduced by a principle similar to an air cushion track, thereby reducing the loss of the surface of the heat shrink tube during transportation, and reducing the heat generated by friction by reducing friction, thereby preventing the heat shrink tube from being deformed due to frictional heat.

[0023] 2. The micro pulley is set to rotate to make the heat shrink tube material move more smoothly during the transportation process, reduce friction resistance, and make the air injected into the pores flow more smoothly through the space of the wheel groove, so that the gas distribution is more uniform, thereby better reducing the contact friction between the heat shrink tube wall and the inner walls of the first tube groove and the second tube groove.

[0024] 3. The main fixture and the auxiliary fixture are matched in appearance and structure. The first tube groove and the second tube groove are matched to form a cylindrical cavity to transport the heat shrink tube material, thereby preventing the tube material from position shifting or vibrating during transportation and improving the stability of tube transportation. The blade can cut the heat shrink tube material through the drive of the micro motor and the rotating shaft. By setting the opening and closing frequency and speed of the micro motor, the tube material with a fixed length and a fixed cross section can be obtained, thereby realizing automatic output of materials with fixed specifications.

[0025] 4. The heat dissipation patch is used to dissipate the heat generated by the auxiliary clamp during the material conveying process, and absorb the heat generated by the main clamp in contact with the auxiliary clamp, so that the inner walls of the first tube groove and the second tube groove always maintain a relatively low temperature, preventing the friction heat that may be generated when the heat shrink tube wall contacts the inner walls of the first tube groove and the second tube groove from accumulating and causing the heat shrink tube material to deform through contact.

[0026] 5. The setting adjustment hole enables the staff to adjust the position of the auxiliary clamp by loosening the one-way bolt when the heat shrink tube is stuck in the first tube groove and the second tube groove, so as to adjust the heat shrink tube material in the first tube groove and the second tube groove, resume production, achieve the purpose of rapid inspection and maintenance, and reduce production costs.

[0045] In summary, when the feeding fixture for heat shrink tubes is used, the main clamp 1 is first placed on the feeding end of the production equipment so that the first tube groove 2 is located on the path of the heat shrink tube pipeline, and then the slide plate 20 is placed inside the first slide groove 5, and the fixing hole 4 and the matching hole 22 are connected and fixed with bolts to make the main clamp 1 and the slide plate 20 tightly connected, and the two-way bolt 25 is inserted into the first connecting hole 3, so that the fixing nut fixed in the middle of the two-way bolt 25 is engaged in the nut groove 11 on one side of the first connecting hole 3, and then the two-way bolt 25 is passed through the third connecting hole 21 on the slide plate 20 near the end of the slide plate 20, and then the thread of the end is connected to the output end of the production equipment or other fixed structure, and fixed with the fixing nut 26, so that the main clamp 1 is stable.

After the micro motor 17 is started, it can drive the blade 19 to rotate. The length of the blade 19 matches the distance from the shaft 18 to the farthest end of the second tube groove 7, so that the blade 19 can cut the heat shrink tube passing through the first tube groove 2 and the second tube groove 7 when rotating. By setting the starting frequency and speed of the micro motor 17, a heat shrink tube with a fixed length and an arc or plane incision can be obtained, thereby achieving the purpose of producing heat shrink tube masterbatch according to the required specifications.To achieve automated processing, and because the auxiliary fixture 6 has some structures inside that will generate heat when moving, the surface of the auxiliary fixture 6 close to the second tube groove 7 is pasted with a heat dissipation sticker 8, which can dissipate the heat generated by these moving structures and prevent this part of the heat from being conducted to the inner wall of the second tube groove 7 and the first tube groove 2, causing the heat shrink tube to deform during transportation. The heat dissipation sticker 8 plays a role in heat dissipation and cooling.
