Description

Technical Field

[0001] This utility model relates to the field of Teflon sleeve production technology, specifically a baking device for Teflon sleeve production. Background Technology

[0002] Teflon tubing can be used as insulation for high-frequency cables, sheaths for coaxial cables, and protection for high-temperature conductors; it can also be used as food-grade tubing for conveying grease or high-temperature liquids.

[0003] During the processing of Teflon sleeves, they undergo baking for shaping. However, during the baking process, after the Teflon sleeve is fitted onto the wire harness, most workers will manually move the Teflon sleeve to the baking area and rotate it back and forth. This operation is inefficient and difficult to keep up with the processing pace. Furthermore, manual operation has poor precision, which not only affects the shaping effect of the Teflon sleeve but also easily causes the wire harness to deform due to heat. Therefore, this utility model proposes a baking device for the production of Teflon sleeves that can solve the above problems. Utility Model Content

[0006] Both the upper cover plate and the lower cover plate are equipped with heating components, and both the upper cover plate and the lower cover plate have arc grooves on their adjacent sides. The two ends of the arc grooves are respectively connected to wire harness receiving grooves, and the two sets of arc grooves can be vertically connected to form a baking cavity.

[0007] The lower cover plate is connected to a moving block via a shifting assembly. The moving block has an elastic groove for clamping the front end of the wire harness. The shifting assembly is used to pull the moving block to move the wire harness.

[0008] A positioning plate is provided on the substrate, and the positioning plate is vertically inserted through the lower cover plate to position and place the Teflon sleeve.

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

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4

[0026] A baking apparatus for the production of Teflon tubing is provided:

[0027] The substrate 10 has a support frame 11, the upper cover plate 30 is fixed to the top of the support frame 11, the lower cover plate 20 is located below the upper cover plate 30 and is movably connected to the support frame 11, and the bottom end of the lower cover plate 20 is connected to a number of guide rods 12, which are inserted through the support frame 11. That is, the lower cover plate 20 can move vertically closer to or away from the upper cover plate 30.

[0028] Both the upper cover plate 30 and the lower cover plate 20 have arc grooves 50 on their adjacent sides. The two ends of the arc grooves 50 are respectively connected to wire harness receiving grooves 51. The wire harness with the Teflon sleeve is supported by the wire harness receiving grooves 51, so that the Teflon sleeve is located at the center of the arc groove 50. When the lower cover plate 20 is vertically close to the upper cover plate 30, the two sets of arc grooves 50 are vertically connected to form a baking cavity, so that the Teflon sleeve is located inside the baking cavity.

[0029] Both the upper cover plate 30 and the lower cover plate 20 are equipped with heating components 40. The heating components 40 include a hot air blower 42 and multiple sets of hot holes 41. The multiple sets of hot holes 41 are distributed on the inner wall of the arc groove 50, and the multiple sets of hot holes 41 are supplied by the hot air blower 42 to discharge hot air toward the center of the arc groove 50. The multiple sets of hot holes 41 are evenly distributed around the center of the inner wall of the arc groove 50. An air guide hood 43 is provided on the outer side of the upper cover plate 30 and the lower cover plate 20. The air guide hood 43 is connected to the multiple sets of hot holes 41. The outlet of the hot air blower 42 is connected to the air guide hood 43. When the two sets of arc grooves 50 are vertically connected to form a baking cavity, the hot holes 41 on the two sets of arc grooves 50 can discharge hot air to evenly bake the Teflon sleeve, resulting in a good shaping effect.

[0030] The upper cover plate 30 and the lower cover plate 20 have openings at both ends of the connecting arc groove 50, which allows the air inside the baking cavity to circulate with the outside air, thus preventing the baking cavity from overheating.

[0031] The lower cover plate 20 is connected to a moving block 60 via a shifting component 70. The moving block 60 has an elastic groove for clamping the front end of the wire harness. The shifting component 70 is used to pull the moving block 60 to move the wire harness. The elastic groove can be made of rubber material. During baking, the front end of the wire harness is clamped by the elastic groove. The shifting component 70 pulls the moving block 60 to move the wire harness, so that the Teflon sleeve on the wire harness moves through the hot air positions discharged by multiple sets of hot air blowers 42, achieving full baking of the Teflon sleeve without the need for manual back-and-forth rotation.

[0032] The shifting assembly 70 includes a lead screw 71 and a motor 72 that drives the lead screw 71 to rotate. The moving block 60 is screwed onto the lead screw 71. The motor 72 is connected to the hot air blower 42 via a signal. A sliding groove 21 is provided on the lower cover plate 20. A slider that slides into the sliding groove 21 is provided on the moving block 60. The motor 72 drives the lead screw 71 to rotate, causing the moving block 60 to move laterally at a uniform speed. When the motor 72 is working, the moving distance of the moving block 60 is controlled according to the required length of the Teflon sleeve to be baked. It can be adapted to Teflon sleeves of different lengths. The motor 72 is connected to the hot air blower 42 via a signal. When the motor 72 stops driving, the hot air blower 42 also stops supplying hot air to the hot hole 41 to avoid the wire harness from being deformed by heat.

[0033] A positioning plate 14 is provided on the substrate 10. The positioning plate 14 is vertically inserted on the lower cover plate 20 to position the Teflon sleeve. When placing the wire harness, the Teflon sleeve can be positioned by contacting the front end of the Teflon sleeve with the positioning plate 14. During the baking operation, as the lower cover plate 20 moves upward, the positioning plate 14 moves downward relative to the Teflon sleeve, which will not interfere with the lateral movement of the Teflon sleeve.

[0034] A lifting cylinder 13 is mounted on the base plate 10. The movable rod of the lifting cylinder 13 is connected to the lower cover plate 20. The lifting cylinder 13 is preferably an electric cylinder, which provides power for the vertical movement of the lower cover plate 20.

[0035] The air inlet pipe of the hot air blower 42 is located outside the arc groove 50. A removable filter screen is installed on the air inlet pipe of the hot air blower 42. The filter screen can be connected to the air inlet pipe of the hot air blower 42 by screws or other connecting parts to filter impurities in the air.

[0036] 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.
