[0017] Figure 2 The diagram shown is a schematic diagram of the hot pressing and setting operation of the hot pressing and setting device for thermoplastic yarn in the embodiment. Detailed Implementation

[0018] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. The components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0019] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0020] Reference Figure 1 and Figure 2 This embodiment provides a heat-pressing and shaping device for thermoplastic yarn (hereinafter referred to as heat-pressing and shaping device 100) for use with a hot air gun 200 to heat-press and shape a thermoplastic yarn, such as a PE polyester yarn 10, onto a fabric, leather or other carrier material.

[0021] The hot pressing and shaping device 100 of this embodiment includes a hot air inlet pipe 2, a movable frame 8, a yarn feed pipe 1 assembled to the hot air inlet pipe 2, and a rotatable pressing wheel unit 7 assembled to the movable frame 8.

[0022] The lower end of the hot air inlet pipe 2 is connected to the movable frame 8 and forms a hot air outlet 22. They are arranged in a cross manner, that is, the hot air inlet pipe 2 is connected to the right end of the movable frame 8 at an angle, and the axial direction of the hot air inlet pipe 2 and the yarn feed pipe 1 is set at an acute angle to form a compact layout.

[0023] The inner cavity of the yarn feed pipe 1 is connected to the inner cavity of the hot air inlet pipe 2, and the yarn outlet 12 of the yarn feed pipe 1 and the hot air outlet 22 of the hot air inlet pipe 2 are respectively corresponding to the hot pressing end 71 of the pressing wheel unit 7 so that the yarn 10 passing through the yarn outlet 12 can be wound around the hot pressing end 71 and the hot air blown out through the hot air outlet 22 is aligned with the yarn 10 wound around the hot pressing end 71, thereby forming a hot pressing and shaping setting for the yarn 10.

[0024] In this embodiment, the pressing wheel unit 7 includes a pressing wheel 71' for hot pressing and shaping and a shaping wheel 72 for secondary shaping. The yarn outlet 12 and the hot air outlet 22 are both close to the pressing wheel 71', and the yarn outlet 12 is located on the circumferential wall of the hot air inlet pipe 2 near the hot air outlet 22. The shaping wheel 72 is located on the left side of the pressing wheel 71' away from the hot air inlet pipe 2. At this time, the pressing wheel 71' is the hot pressing end 71 of the pressing wheel unit 7.

[0025] like Figure 2As shown, during operation, the yarn 10 is first introduced into the yarn inlet 11 of the yarn feed pipe 1, and passes through the yarn outlet 12 and the hot air outlet 22 in sequence until it is wound around the pressure roller 71' and the shaping roller 72. Then, the hot air gun 200 is inserted into the hot air inlet pipe 2, and the hot air generated after the hot air gun 200 is powered on is blown onto the yarn 10 on the pressure roller 71' through the hot air outlet 22 to heat the yarn 10 to a shaped state. Then, the prepared hot pressing and shaping device 100 is placed on the fabric and moved, and the yarn 10 is hot-pressed and shaped onto the fabric by relying on the hot air gun 200, the pressure roller 71' and the shaping roller 72.

[0026] By cooperating with the movable frame 8, the pressure wheel unit 7, and the hot air inlet pipe 2 equipped with the yarn feed pipe 1, and inserting the hot air gun 200 into the hot air inlet of the hot air inlet pipe 2, the malleable yarn 10 is heated and shaped, and then hot-pressed onto the fabric, leather, or other supporting materials. This reduces the difficulty of the hot pressing and shaping operation of the yarn 10, making it easier for operators to use it for hot pressing and shaping of the thermoplastic yarn 10.

[0027] Of course, in other embodiments, the setting wheel 72 may not be necessary, and the yarn 10 can still be hot-pressed and set; the number of setting wheels 72 may also be two or more.

[0028] Further preferred, such as Figure 1 As shown, the movable frame 8 has multiple adjustment holes 9 distributed along its length and spaced apart. The shaping wheel 72 is detachably mounted in each adjustment hole 9 to adjust the distance between the pressing wheel 71' and the shaping wheel 72 to meet the production process requirements of different products.

[0029] Further preferred, such as Figure 1 As shown, the surfaces of the pressing wheel 71' and the shaping wheel 72 are respectively provided with grooves that match the diameter of the thermoplastic yarn 10, so as to ensure that the yarn 10 will not slip off the surfaces of the pressing wheel 71' and the shaping wheel 72 during the hot pressing and shaping process.

[0030] In another preferred embodiment, such as Figure 1 As shown, a height-adjustable telescopic rod assembly 3 is provided on the upper right side of the hot air inlet pipe 2 away from the mobile frame 8, and a walking roller 5 for support is provided on the telescopic end of the telescopic rod assembly 3 away from the hot air inlet pipe 2.

[0031] More specifically, the telescopic rod assembly 3 includes a fixed sleeve 31 connected to the hot air inlet pipe 2 and a movable rod 32 inserted into the fixed sleeve 31, and a limiting member 6 for adjusting the telescopic height of the movable rod 32 is provided between the fixed sleeve 31 and the movable rod 32.

[0032] The lower end of the movable rod 32, which is away from the fixed sleeve 31, is equipped with a roller bracket 4, and the roller bracket 4 is equipped with a traveling roller 5.

[0033] In this specific embodiment, the limiting member 6 is an adjusting screw, and the fixing sleeve 31 has a plurality of positioning holes 311 distributed along its axial direction to correspond to different support heights of the telescopic rod assembly 3.

[0034] When the limiting member 6 passes through one of the positioning holes 311 and abuts against the movable rod 32 inside the fixed sleeve 31, the limiting member 6 restricts the movable rod 32 from telescopic movement within the fixed sleeve 31, thereby adjusting the support height of the telescopic rod assembly 3 to the height required by the production process. At the same time, the entire hot pressing and shaping device 100 is rotated to a suitable angle with the pressure wheel 71' as the rotation fulcrum, so as to adjust the angle between the hot pressing and shaping device 100 and the fabric surface, thereby making the fabric after the yarn 10 hot pressing and shaping more uniform.

[0035] Furthermore, in the prior art, the hot air gun 200 cannot effectively heat press and shape the yarn 10 with a fine diameter. The heat pressing and shaping device 100 of this embodiment can heat press and shape the yarn 10 onto the fabric along a preset trajectory, and the entire device has a simple structure and is relatively easy to operate.

[0036] Of course, in other embodiments, the limiting member 6 can also be a retractable elastic bead and installed on the movable rod 32, and the elastic bead can be detachably snapped into each positioning hole 311 of the fixed sleeve 31, so that the telescopic height can also be adjusted.

[0037] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
