Description

Technical Field

[0001] The utility model relates to the technical field of creel tensioning, in particular to a creel tensioning device. Background Art

[0002] A woven bag, also known as a snake skin bag, is a type of plastic bag used for packaging. It is generally white or grayish white in color, non-toxic and odorless, and generally causes little harm to the human body. Although it is made of various chemical plastics, it has strong environmental protection and a large recycling rate. The plastic woven bag is mainly made of polypropylene resin, extruded and stretched into flat filaments, and then woven and bagged. During the preparation process of the plastic woven bag, after the raw materials are stretched into flat filaments, they are wound into bobbins. The bobbins need to be placed on a creel. The creel leads out the flat filaments and finally sends them into a knitting machine through a wire guiding device for weaving. The bobbins are clamped on the creel by clamping parts, and the wire guiding device provides power to drive the bobbins to rotate and feed wire. During long-term use, since the bobbins need to be repeatedly removed and installed, the clamping parts are prone to losing tension, resulting in different rotation speeds of multiple bobbins, uneven wire feeding, and causing the finally woven woven bag to have particle protrusions and unevenness, and local weaving tension or looseness. Summary of the Utility Model

[0003] The utility model aims to provide a creel tensioning device to solve the problem that the tensioning workpiece of the existing creel's limited winding loses its tension after long-term use and cannot clamp the bobbin.

[0004] To solve the above technical problems, the utility model provides the following technical solution: A creel tensioning device includes a creel body and a plurality of yarn bobbin shafts installed on the creel. Clamping parts are symmetrically arranged at both ends of the yarn bobbin shaft, and a plurality of elastic ropes are connected between the clamping parts. The elastic ropes are used to maintain the tension between the clamping parts.

[0005] Working principle of the utility model: When the knitting process needs to be carried out, the bobbin slides along the clamping parts outside the yarn bobbin shaft and stops moving when the bottom end of the bobbin approaches the clamping part inside the yarn bobbin shaft. At this time, the external clamping part passes through the outer end of the bobbin, and the clamping parts at both ends clamp the bobbin on the yarn bobbin shaft.

[0006] Advantages of the utility model: 1. By clamping and fixing both ends of the bobbin, the stability of the bobbin on the creel is effectively improved, avoiding the displacement of the bobbin during use due to vibration or external force. 2. The process of installing and removing the bobbin is simple. Through the action of the elastic rope, the bobbin can be quickly installed and removed without complex adjustment. 3. By ensuring the stable position of the bobbin, the fluctuation of the rotation speed of the bobbin during the knitting process is reduced, thereby improving the flatness and consistency of the woven bag.

[0007] Further, the clamping member includes a clamping ring and a plurality of clamping pieces arranged along the outer edge of the clamping ring. The clamping ring is semi-conical, and the bottoms of the semi-conical shapes of the plurality of clamping rings face each other. The central axis positions of the plurality of clamping rings are symmetrically connected to both ends of the yarn bobbin shaft, and a plurality of elastic ropes are vertically connected between the corresponding clamping pieces. During operation, the bobbin moves along the outer clamping ring. When the bobbin moves to the clamping ring at the inner end of the yarn bobbin shaft, the bobbin continues to move and squeezes the clamping pieces, causing the outer clamping ring and the clamping pieces to come out from the outer end of the bobbin. At this time, the outer clamping pieces clamp the outer end of the bobbin. Then, when the bobbin is released, the clamping pieces at both ends maintain the state of clamping the bobbin under the action of the elastic ropes.

[0008] Further, a filling block is connected to the middle of the yarn bobbin shaft, and the size of the filling block is the same as the inner cross-section of the bobbin. Through the setting of the filling block, the bobbin can be further clamped.

[0009] Further, the plurality of elastic ropes penetrate along the outer edge of the filling block. Through the setting of the elastic rope limit, the outer ends of the elastic ropes can be protected to avoid friction between the elastic ropes and the inner wall of the bobbin.

[0010] Further, the diameter of the circle formed by the outer edges of the plurality of clamping pieces is greater than the diameter of the bobbin. Through the setting of the size of the clamping pieces, the clamping pieces can clamp the bobbin more firmly.

[0011] Further, the clamping pieces are made of an elastic material. By selecting the elastic material, the clamping pieces can quickly return to their original state. Description of the Drawings

[0013] Figure 2 is a side cross-sectional view of the tensioning device for a creel of the present utility model during use. Detailed Description of the Preferred Embodiments

[0014] The following is a more detailed description through specific embodiments:

[0015] The reference numerals in the drawings of the specification include: clamping ring 1, clamping piece 2, yarn bobbin shaft 3, filling block 4, elastic rope 5, bobbin 6.

[0016] The embodiment is basically as shown in the attached Figure 1 - attached Figure 2As shown in the figure: A creel tensioning device includes a creel body and a yarn bobbin shaft 3 arranged on the creel. A filling block 4 is fixedly connected to the middle of the yarn bobbin shaft 3. The size of the filling block 4 is the same as the inner cross-section of the bobbin 6. Clamping rings 1 are symmetrically and fixedly connected to both ends of the yarn bobbin shaft 3. The clamping rings 1 are semi-conical. The larger-diameter ends of the two clamping rings 1 face each other. Three clamping pieces 2 are fixedly connected to the outer edge of the clamping ring 1. The clamping pieces 2 are made of an elastic material. The diameter of the circle formed by the outer edges of the three clamping pieces 2 is larger than the diameter of the bobbin 6. An elastic rope 5 is fixedly connected between the opposite clamping pieces 2. The elastic rope 5 passes through the outer edge of the filling block 4.

[0017] The specific implementation process is as follows: When the knitting process needs to be carried out, the bobbin 6 moves along the outer clamping ring 1. When the bobbin 6 moves to the clamping ring 1 at the inner end of the yarn bobbin shaft 3, at this time, the inside of the bobbin 6 is in close contact with the filling block 4. The bobbin 6 continues to move and squeezes the clamping piece 2, so that the outer clamping ring 1 and the clamping piece 2 come out from the outer end of the bobbin 6. At this time, the outer clamping piece 2 clamps the outer end of the bobbin 6. Then the bobbin 6 is released. The clamping pieces 2 at both ends maintain the state of clamping the bobbin 6 under the action of the elastic rope 5. At this time, the filling block 4 also clamps the bobbin 6. After use, the bobbin 6 is squeezed towards the inner clamping piece 2. Under the action of the elastic rope 5, the outer clamping piece 2 will contract inwards. When the clamping piece 2 contracts to a size that can pass through the inside of the bobbin 6, at this time, the bobbin 6 is driven to move in the reverse direction until it is separated from the yarn bobbin shaft 3.
