Description

Technical Field

[0001] The utility model relates to a fine fiber yarn collector of a spinning frame, belonging to the technical field of spinning frame parts. Background Art

[0002] The spinning frame is the main machine for spinning. In the spinning process, the semi-finished coarse fiber yarn or sliver needs to be drawn, twisted, and wound into a fine fiber yarn bobbin. In the existing spinning frame, a collector is usually used to gather the coarse fiber yarn into a fine fiber yarn. The specific structure is shown in the attached Figure 1 A bundling port is provided on the top of the collector, and the bundling port is trumpet-shaped. When in use, one end of the coarse fiber yarn enters along the large-diameter bundling port, and after passing through the small-diameter bundling port, the coarse fiber yarn will be bundled into a fine fiber yarn. Since the diameter of the bundling port of the existing collector is fixed, it cannot meet the bundling needs of fine fiber yarns of different diameters. A separate collector is designed for each fine fiber yarn of each diameter, which requires high cost. In subsequent use, the large number of collectors is not convenient for storage, and there is also a risk of confusion. The adaptability of the collector is poor, and therefore, it is necessary to improve it. Summary of the invention

[0003] The utility model aims to provide a fine fiber yarn collector for a spinning machine to solve the problem that the existing collector has a fixed diameter of a collecting opening, poor adaptability and cannot meet the collection requirements of fine fiber yarns of different diameters.

[0004] The technical solution of the utility model is:

[0005] A fine fiber yarn collector for a spinning machine includes a collector body, and is characterized in that: a mounting groove is opened at the top of the collector body, arc pieces are symmetrically arranged in the mounting groove, one end of the arc piece is hinged to the inner bottom surface of the mounting groove through a pin shaft, the arc piece is connected to the inner bottom surface of the mounting groove in a sliding contact, a tension spring is arranged between the other end of the arc piece and the inner wall of the mounting groove, and yield grooves are arranged on the collector body on both sides of the mounting groove, and an adjustment limit assembly is installed in the yield groove, and the adjustment limit assembly cooperates with the arc piece in a sliding contact connection.

[0006] The arc pieces are arranged in an "eight" shape.

[0007] The adjustment limit assembly includes a connecting rod, which is arranged in the give way groove. A main shaft is fixedly installed at the corresponding position between the connecting rod, the arc piece and the inner wall of the installation groove. A limit wheel is movably installed on the main shaft through a bearing. The limit wheel is arranged between the arc piece and the inner wall of the installation groove, and the limit wheel is in contact with the arc piece.

[0008] The installation groove and the clearance groove are respectively rectangular grooves, and the clearance groove and the installation groove are arranged in a stepped shape.

[0009] The give way slot is provided with a plurality of jacks.

[0010] The jacks are arranged in a straight line on the clearance slot.

[0011] A plug post is arranged on the connecting rod corresponding to the jack, and the plug post is plugged into the jack by interference fit.

[0012] The beneficial effects of the utility model compared with the prior art are:

[0013] The fine fiber yarn collector of the spinning frame changes the relative position of the two limiting wheels by adjusting the connecting rod and the plug post of the limiting assembly to cooperate with different sockets. Because the arc piece will always maintain contact and connection with the limiting wheel under the tension of the tension spring, when the relative position of the two limiting wheels changes, the spacing between the arc pieces will also change accordingly, so that the spacing between the arc pieces can adapt to the coarse fiber yarns to be bundled into fine fiber yarns of different diameters, thereby reducing production costs. The fine fiber yarn collector of the spinning frame has strong adaptability and simple structure, which can effectively reduce the number of collectors that are inconvenient to store and avoid the risk of confusion during use.

[0019] As attached Figure 1-4 Shown

[0020] The fine fiber yarn collector of the spinning frame includes a collector body 1, a mounting groove 2 is opened at the top of the collector body 1, the mounting groove 2 is a rectangular groove, arc pieces 3 are symmetrically arranged in the mounting groove 2, and the arc pieces 3 are arranged in an "eight" shape. The purpose of such arrangement is to facilitate the coarse fiber yarn to enter from the end with a larger diameter between the arc pieces 3, and then be led out from the end with a smaller diameter between the arc pieces 3, thereby bundling the coarse fiber yarn into fine fiber yarn.

[0021] One end of the arc piece 3 is hinged to the inner bottom surface of the mounting groove 2 through a pin shaft 12, and the arc piece 3 is connected to the inner bottom surface of the mounting groove 2 by sliding contact. A tension spring 4 is arranged between the other end of the arc piece 3 and the inner wall of the mounting groove 2. When working, the arc piece 3 can rotate around the pin shaft 12 in the mounting groove 2, so as to facilitate the later adjustment of the spacing between the arc pieces 3.

[0022] The collector body 1 on both sides of the installation groove 2 is provided with clearance grooves 5, which are rectangular grooves. The clearance grooves 5 and the installation groove 2 are arranged in an up and down step shape. The purpose of this arrangement is to facilitate the installation of the adjustment limit assembly and prevent the adjustment assembly from bulging outward and affecting normal assembly.

[0023] An adjustment limit assembly is installed in the give way groove 5, and the adjustment limit assembly includes a connecting rod 6, which is arranged in the give way groove 5, and a main shaft 7 is fixedly installed at a corresponding position between the connecting rod 6 and the arc piece 3 and the inner wall of the installation groove 2. A limit wheel 8 is movably installed on the main shaft 7 through a bearing, and the limit wheel 8 is arranged between the arc piece 3 and the inner wall of the installation groove 2. The limit wheel 8 is in contact with the arc piece 3. When working, the arc piece 3 can be limited by the limit wheel 8. Under the tension of the tension spring 4, the arc piece 3 maintains contact with the limit wheel 8, so that a certain spacing can be maintained between the arc pieces 3, which is convenient for subsequent bundling operations.

[0024] The limiting wheel 8 of the adjusting limiting assembly is connected with the arc piece 3 in sliding contact. The purpose of such setting is to form rolling friction between the limiting wheel 8 and the arc piece 3. When the arc piece 3 is adjusted in action, the friction loss between the arc piece 3 and the limiting wheel 8 is effectively reduced, thereby extending its service life.

[0025] A plurality of sockets 9 are provided on the clearance groove 5, and the sockets 9 are arranged in a straight line on the clearance groove 5. A plug post 10 is provided on the connecting rod 6 corresponding to the socket 9, and the plug post 10 is plugged into the socket 9 with interference fit. When in use, the relative position of the connecting rod 6 is changed by making the plug post 10 on the connecting rod 6 cooperate with different sockets 9. When the relative position of the connecting rod 6 changes, the connecting rod 6 drives the relative position of the limiting wheel 8 to change. Since the arc piece 3 maintains contact and connection with the limiting wheel 8 under the tension of the tension spring 4, when the relative position of the limiting wheel 8 changes, the spacing between the arc pieces 3 also changes.

[0026] When the fine fiber yarn collector of the spinning frame is in use, the coarse fiber yarn is first inserted from the end with a larger diameter between the arc pieces 3, and is then passed out from the end with a smaller diameter between the arc pieces 3, and then the collector is installed on the spinning frame. When the spinning frame is working, the coarse fiber yarn moves along the end with a larger diameter between the arc pieces 3 to the end with a smaller diameter, and under the action of the arc pieces 3, the coarse fiber yarn is gathered into fine fiber yarn.

[0027] When it is necessary to adjust the diameter of the fine fiber yarn after bundling, first remove the collector and pull the connecting rod 6 to disengage the plug 10 of the connecting rod 6 from the socket 9. At this time, keep the limiting wheel 8 in contact with the arc piece 3 and move the connecting rod 6 upward. The connecting rod 6 drives the limiting wheel 8 to move upward so that the plug 10 of the connecting rod 6 matches and corresponds to another socket 9 and is inserted. After the insertion is completed, the arc piece 3 always keeps in contact with the limiting wheel 8 under the elastic force of the tension spring 4. After the limiting wheel 8 moves upward, the arc piece 3 swings synchronously with the limiting wheel 8 around the pin shaft 12 under the elastic force of the tension spring 4, and the two arc pieces 3 open outward, thereby increasing the distance between the arc pieces 3, thereby making the bundling The diameter of the fine fiber yarn coming out becomes larger; on the contrary, the connecting rod 6 is pulled to disengage the plug post 10 of the connecting rod 6 from the socket 9. At this time, the limiting wheel 8 is kept in contact with the arc piece 3, and the connecting rod 6 is moved downward. The connecting rod 6 drives the limiting wheel 8 to move downward, so that the plug post 10 of the connecting rod 6 corresponds to the other socket 9 and is inserted. After the insertion is completed, the arc piece 3 always keeps in contact with the limiting wheel 8 under the elastic force of the tension spring 4. After the limiting wheel 8 moves downward, the arc piece 3 swings synchronously around the pin shaft 12 and follows the limiting wheel 8 under the elastic force of the tension spring 4. The two arc pieces 3 move inwardly, thereby reducing the distance between the arc pieces 3, thereby reducing the diameter of the fine fiber yarn that is gathered.

[0028] The fine fiber yarn collector of the spinning frame changes the relative positions of the two limiting wheels 8 by adjusting the connecting rod 6 and the plug 10 of the limiting assembly to cooperate with different sockets 9. Since the arc piece 3 will always maintain contact and connection with the limiting wheel 8 under the tension of the tension spring 4, when the relative positions of the two limiting wheels 8 change, the spacing between the arc pieces 3 also changes accordingly, so that the spacing between the arc pieces 3 can adapt to the bundling of coarse fiber yarns into fine fiber yarns of different diameters, thereby reducing production costs. Compared with the fixed-diameter bundling mouth 11 of the existing collector, the fine fiber yarn collector of the spinning frame has strong adaptability and simple structure, which effectively reduces the number of collectors that are inconvenient to store and avoids the risk of confusion.
