Description

Technical Field

[0001] This utility model relates to the field of heat dissipation roller technology, specifically a heat dissipation roller assembly for DTY processing. Background Technology

[0002] A texturing machine is a textile machine that can process POY (polyester) into DTY (polyester elastic yarn) with medium and low elasticity through false twisting. It uses physical methods to twist nylon and polyester fibers of equal length (POY·FDY) approximately 3,000–4,000 times / m, followed by heat treatment and then back twisting to create fine curls, thus producing DTY yarn with good bulk, high elasticity, and stretch. Rollers are cylindrical rotating parts in textile machinery that perform feeding, drafting, and output functions, widely used in drafting, carding, and conveying mechanisms. The heat generated by the friction between the roller sleeve surface and the textile yarn can damage the textile if the roller sleeve is not properly cooled. However, current roller assemblies have poor heat dissipation performance and struggle to quickly dissipate heat. Therefore, we propose a heat-dissipating roller assembly for DTY processing.

[0005] Furthermore, the heat dissipation assembly includes four sets of heat-conducting rods disposed inside the roller sleeve, and heat dissipation fins are disposed on both the left and right side walls of the roller sleeve.

[0017] 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.

[0018] Example 1:

[0019] Please see Figure 1-3 This utility model provides a technical solution: a heat dissipation roller assembly for DTY processing, including a rotating shaft 1, a roller sleeve 2 sleeved on the outer wall of the rotating shaft 1, multiple sets of grooves 4 are opened on the outer wall of the roller sleeve 2, and a heat dissipation assembly 3 is provided inside the roller sleeve 2.

[0020] The heat dissipation assembly 3 includes four sets of heat-conducting rods 30 disposed inside the roller sleeve 2. The four sets of heat-conducting rods 30 are arranged in a ring array inside the roller sleeve 2. Multiple sets of heat-absorbing blocks 31 are provided on the outer side wall of the heat-conducting rods 30. Heat dissipation fins 32 are provided on both the left and right side walls of the roller sleeve 2. The two ends of the four sets of heat-conducting rods 30 are respectively connected to the opposite side walls of the two sets of heat dissipation fins 32. Under the action of the heat-absorbing blocks 31, heat can be absorbed and transferred to the heat dissipation fins 32 through the heat-conducting rods 30 for heat dissipation. Multiple sets of first heat dissipation grooves 33 are provided on the outer side wall of the heat dissipation fins 32. Multiple sets of second heat dissipation grooves 34 are provided on the outer side wall of the heat dissipation fins 32 and connected to the first heat dissipation grooves 33. The first heat dissipation grooves 33 are arranged in an arc shape. With the cooperation of the first heat dissipation grooves 33 and the second heat dissipation grooves 34, the contact area between the heat dissipation fins 32 and the air can be increased, thereby improving the heat dissipation effect.

[0021] Working principle: During DTY processing, the rotating shaft 1 drives the roller sleeve 2 to rotate, and under the action of the thread groove 4, it can contact the textile thread. The friction generated will cause the temperature of the roller sleeve 2 to rise. Under the action of the heat absorption block 31, the heat can be absorbed and transferred to the heat sink 32 through the heat conduction rod 30 for heat dissipation. With the cooperation of the first heat dissipation groove 33 and the second heat dissipation groove 34, the contact area between the heat sink 32 and the air can be increased, and the heat dissipation effect can be improved. Because the rotation of the rotating shaft 1 will drive the heat sink 32 to rotate, the first heat dissipation groove 33 and the second heat dissipation groove 34 can fully contact the air.

[0022] 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.
