Description

Technical Field

[0001] This utility model relates to the field of twisting machine technology, and in particular to an integrated composite twisting machine. Background Technology

[0002] In the field of composite twisting machines for yarn twisting in the textile industry, the existing frame and spindle arrangements of composite twisting machines, both domestically and internationally, fall into two categories:

[0003] The first method involves integrating the upper primary twist and the lower secondary twist together on a single frame, with the yarn from the upper primary twist being introduced into the lower secondary twist.

[0004] Advantages and disadvantages: This structure is efficient when producing fine yarns due to the large number of spindles, but it is extremely inconvenient for workers to operate when producing medium to coarse yarns because the raw material yarn fed into the upper layer of the initial twist is large in size.

[0005] The second type: the initial twisting and retwisting are completed by three frames. That is, the retwisting is done by a single frame placed in the middle, while the initial twisting requires at least two frames placed on the left and right sides of the retwisting frame. The initial twisted yarn on the spindles of the initial twisting frames on the left and right sides is guided to the retwisting spindle on the middle frame for retwisting.

[0006] Advantages and disadvantages: This structure is more convenient for employees to operate than the first one, but it requires three frames to complete the initial and re-twisting process, which takes up a large space and the operating range of employees is also larger. In addition, the yarn channel is too long and the quality of the twisted yarn is poor. Utility Model Content

[0007] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an integrated composite twisting machine with an integrated frame design, which is compact, occupies little space, greatly facilitates employee operation, and produces high-quality twisted yarn.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] An integrated compound twisting machine includes an integrated frame, which comprises a primary twisting frame and a secondary twisting frame fixed together side by side. The primary twisting frame and the secondary twisting frame are no longer separate but connected as a whole.

[0010] The primary twisting frame consists of two layers. The upper primary twisting frame has two symmetrical rows of primary twisting spindles, with 2-4 spindles in each row. The lower primary twisting frame also has two symmetrical rows of primary twisting spindles, with 2-4 spindles in each row. The secondary twisting frame has two secondary twisting spindles, arranged symmetrically at the same horizontal level, forming a 2x2 array. A bobbin is mounted on each secondary twisting spindle.

[0011] The initial twisting frame is equipped with an initial twist guide and a yarn tensioning device corresponding to the initial twisting spindle. The retwisting frame is equipped with rollers and a retwisting guide corresponding to the retwisting spindle. Each bobbin is fitted with a ring, which is mounted on the retwisting frame via a ring lifting device. Specifically, the ring includes a ring collar and a ring collar seat connected together. The ring collar is outside the bobbin, and the ring collar seat is connected to the ring lifting device on the retwisting frame. The ring lifting device allows the ring collar to move up and down, ensuring that the twisted yarn is evenly wound onto the bobbin.

[0012] The raw yarns on every 2 to 4 initial twisting spindles are first initially twisted by the initial twisting guide and then gathered together by the yarn guiding tension device. They then enter the retwisting frame and pass through the rollers and retwisting guide in sequence, and finally enter the bobbin on the retwisting spindle through the steel guide to complete the compound twisting yarn.

[0013] Preferably, the number of initial twisting spindles in each row on the upper initial twisting frame is 3, and the number of initial twisting spindles in each row on the lower initial twisting frame is 3.

[0014] Preferably, a yarn tension guiding device is provided on the side of the retwisting frame near the initial twisting frame. The yarn tension guiding device maintains uniform tension, ensuring consistent twist and a compact structure.

[0015] Preferably, the two rows of initial twisting spindles on the upper initial twisting frame and the two rows of initial twisting spindles on the lower initial twisting frame are staggered. Specifically, the two rows of initial twisting spindles on the upper layer are close to the middle position of the initial twisting frame, and the two rows of initial twisting spindles on the lower layer are close to the front and rear sides of the initial twisting frame.

[0016] The beneficial effects of this utility model are as follows: the twisting machine frame of this utility model adopts an integrated design, which is compact in structure, occupies little space, greatly facilitates the operation of employees, and produces good twisting quality.

[0024] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0025] Example 1: As Figure 1-2 As shown, an integrated compound twisting machine includes an integrated frame 10, which includes a primary twisting frame 11 and a secondary twisting frame 12 fixed together side by side.

[0026] The primary twisting frame 11 is divided into upper and lower layers. The upper primary twisting frame 11 has two rows of primary twisting spindles 20 symmetrically distributed, with 2 to 4 spindles 20 in each row. The lower primary twisting frame 11 also has two rows of primary twisting spindles 20 symmetrically distributed, with 2 to 4 spindles 20 in each row. The retwisting frame 12 has two retwisting spindles 30 symmetrically distributed in two rows at the same horizontal height. Each row of retwisting spindles 30 has a bobbin 13 mounted on it.

[0027] Furthermore, the initial twisting frame 11 is equipped with an initial twisting yarn guide 14 and a yarn tensioning device 15 corresponding to the initial twisting spindle 20, and the retwisting frame 12 is equipped with a roller 16 and a retwisting yarn guide 17 corresponding to the retwisting spindle 30. Each bobbin 13 is fitted with a steel ring 18, which is mounted on the retwisting frame 12 via a steel ring lifting device 19. Figure 3-4 As shown, the steel ring lifting device 19 is installed in the middle position of the retwisting machine frame 12.

[0028] The twisting process is as follows: every 2 to 4 initial twisting spindles 20, the raw yarn is first twisted by the initial twisting guide 14 and then gathered together by the yarn guiding tension device 15. Then it enters the retwisting frame 12 and passes through the roller 16 and the retwisting guide 17 in sequence. Finally, it is guided by the steel ring 18 to the bobbin 13 on the retwisting spindle 30 to complete the compound twisting.

[0029] Example 2: Combination Figure 1 As shown, based on Embodiment 1, the number of initial twisting spindles 20 in each row on the upper initial twisting frame 11 is 3, and the number of initial twisting spindles 20 in each row on the lower initial twisting frame 11 is 3.

[0030] Example 3: Combination Figure 1 As shown, based on Embodiment 1 or Embodiment 2, a yarn guiding tension device 15 is provided on the side of the retwisting frame 12 near the initial twisting frame 11. After the initial twisted yarn enters the retwisting frame 12, it maintains uniform tension to ensure consistent twist and compact structure.

[0031] Example 4: Combination Figure 2 As shown, based on Embodiment 1, Embodiment 2 or Embodiment 3, the two rows of primary twisting spindles 20 on the upper primary twisting frame 11 and the two rows of primary twisting spindles 20 on the lower primary twisting frame 11 are staggered. Specifically, the two rows of primary twisting spindles 20 on the upper layer are close to the middle position of the primary twisting frame 11, and the two rows of primary twisting spindles 20 on the lower layer are close to the front and rear sides of the primary twisting frame 11.
