Description

Technical Field

[0001] This utility model relates to the field of loom technology, specifically to a quick shuttle changing device for looms. Background Technology

[0002] Traditional shuttles are mostly made of wood, such as persimmon and oak. Although modern shuttles are also made of materials like nylon, their overall structure remains relatively simple. Their shape and structure often only meet the basic function of weft insertion, making it difficult to meet the demands of high-efficiency production under high-speed operation or complex weaving processes. For example, in the shuttles used on ordinary looms, the bobbin is inserted into a bobbin with spring plates, and the bobbin is supported by a base spring. This structure is prone to loosening due to vibration during high-speed weaving, affecting the normal weft insertion and weaving quality.

[0003] The existing technology has the following defects or problems: Existing technology, disclosed in CN221460633U, provides a loom including a shedding mechanism, a weft insertion mechanism, a weft beating mechanism, a take-up mechanism, a warp feed mechanism, an air supply device, and a first frame and a second frame arranged opposite to each other. The shedding mechanism, weft beating mechanism, take-up mechanism, and warp feed mechanism are located between the first frame and the second frame, and the weft insertion mechanism is connected to the weft beating mechanism. The first frame and the second frame are connected by a front beam, and the front beam has a front beam air supply channel. The air supply device is pneumatically connected to the weft insertion mechanism and the front beam air supply channel. This utility model loom sets a front beam air supply channel in the front beam. Air is supplied to the front beam air supply channel and the weft insertion mechanism through the air supply device to achieve the cooperation between the front beam air supply channel and the weft insertion mechanism for weft insertion and beating. This eliminates the need for an additional air supply structure to cooperate with the weft insertion mechanism, reducing the space occupied by the air supply structure, and does not hinder the structural layout of the various components of the loom. The loom is small in size, low in cost, and multiple looms can be equipped in the same factory, resulting in high fabric output for the manufacturer.

[0004] The aforementioned equipment makes it difficult to quickly change the shuttle, requiring manual operation. This necessitates shutting off the loom power, disassembling the old shuttle, and installing the new one, a process that can take several minutes or even longer. During this time, the loom cannot function normally, severely impacting production efficiency. However, in existing technologies, some looms using quick shuttle changing devices cannot accurately receive change information, leading to problems in the coordination between various stages, further affecting production efficiency and product quality.

[0005] It should be noted that the above content falls within the inventor's technical knowledge and does not necessarily constitute prior art. Utility Model Content

A rotating shaft is rotatably connected inside the support plate, and a gear is fixedly connected to the outside of the rotating shaft. The external teeth of the rack plate and the external teeth of the gear are meshed. A swing arm is fixedly connected to the right side of the rotating shaft, and a crossbar is fixedly connected to the adjacent side of the top ends of the two swing arms. An opening is formed at the top right side of the crossbar.

[0009] As a preferred embodiment of this utility model, the outer surfaces of the plurality of shuttles are in contact with the inner wall of the placement groove, and the outer surface of the probe is slidably connected to the top inner wall of the support plate on the right side.

[0010] As a preferred embodiment of this utility model, the push rod is externally fixedly connected to the inner wall of the rear top of the support plate on the right side, and the outer surfaces of the plurality of shuttles are in contact with the outer surfaces of the two limiting blocks.

[0013] As a preferred embodiment of this utility model, the bottom end of the crossbar contacts the inner wall of the bottom end of the two grooves, and the inner wall of the opening contacts the outside of the plurality of shuttles.

[0014] Compared with the prior art, the present invention provides a quick shuttle changing device for a loom, which has the following advantages:

[0015] 1. A quick shuttle changing device for a loom, comprising a push rod, a shuttle, a placement groove, a crossbar, a contact plate, and a probe, wherein a drive assembly is activated, causing the crossbar to contact the contact plate, the contact plate to apply pressure to the probe, the probe transmitting a signal to the push rod, the push rod activating and pushing the shuttle, causing the shuttle to slide in the placement groove, then slide out of the placement groove and enter the crossbar through an opening, wherein a through hole is provided on the left side of the crossbar for discharging the replaced shuttle, thereby reducing the response time of a large amount of manual operation or complex mechanical structure, significantly shortening the shuttle changing cycle, enabling the loom to resume weaving work more quickly, and improving overall production efficiency.

[0016] 2. A quick shuttle changing device for a loom, comprising an electric telescopic rod, a rack plate, a gear, a swing arm, and a crossbar. When the electric telescopic rod is activated, the rack plate drives the gear to rotate, which in turn drives the swing arm and the crossbar to move. This causes the swing arm to swing around the rotation axis, thereby making the crossbar contact the probe and transmitting the change information. This significantly shortens the time from receiving the instruction to starting the shuttle changing action, thus significantly improving the shuttle changing efficiency. Attached Figure Description

[0022] 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.

[0023] Example 1

[0024] Please see Figure 1-4 In this embodiment: a quick shuttle changing device for a loom includes two support plates 1. A placement groove 2 is formed inside the rear top of the right support plate 1. Multiple shuttles 3 are placed in the placement groove 2. The outer surfaces of the multiple shuttles 3 contact the outer surfaces of two limiting blocks 7, and the outer surfaces of the multiple shuttles 3 contact the inner wall of the placement groove 2. A push rod 4 is fixedly connected to the rear top of the right support plate 1. The outer surface of the push rod 4 is fixedly connected to the inner wall of the rear top of the right support plate 1. The output end of the push rod 4 contacts the rear side of the shuttles 3. The probe 5 is internally slidably connected, and the probe 5 is externally slidably connected to the inner wall of the top of the right support plate 1. The front side of the probe 5 is fixedly connected to the contact plate 6. The inside of the placement groove 2 is provided with two limiting blocks 7. The front end of the two support plates 1 is fixedly connected to the front end of the adjacent side. The rear bottom end of the two support plates 1 is fixedly connected to the adjacent side. The left and right sides of the connecting rod 10 are fixedly connected to the rear bottom end of the two support plates 1. The top of the two support plates 1 is provided with a groove 9. The inner wall of the two support plates 1 is respectively provided with a drive component.

[0025] In this embodiment, when the shuttle 3 needs to be replaced, the drive assembly is activated, causing the crossbar 18 to contact the contact plate 6. The contact plate 6 applies pressure to the probe 5, and the probe 5 transmits a signal to the push rod 4. The push rod 4 is activated and pushes the shuttle 3, causing the shuttle 3 to slide in the placement groove 2 and then slide out of the placement groove 2 and enter the crossbar 18 through the opening 19. A through hole is provided on the left side of the crossbar 18 for discharging the replaced shuttle 3. The limiting block 7 restricts the position of the shuttle 3, ensuring that the shuttle 3 is neatly arranged in the placement groove 2 and does not move randomly. The connecting roller 8 plays an auxiliary role in the overall operation of the loom, guiding the fabric and working in conjunction with the shuttle changing device to ensure the continuity of the weaving process.

[0026] Example 2

[0027] like Figure 1 - Figure 4As shown, the drive assembly includes two support plates 1. The bottom end of the support plate 1 has a receiving groove 11, and the top end of the support plate 1 has a sliding groove 12. An electric telescopic rod 13 is fixedly connected to the front side of the support plate 1. A rack plate 14 is fixedly connected to the output end of the electric telescopic rod 13. A rotating shaft 15 is rotatably connected inside the support plate 1. A gear 16 is fixedly connected to the outside of the rotating shaft 15. The external teeth of the rack plate 14 and the external teeth of the gear 16 are meshed. A swing arm 17 is fixedly connected to the right side of the rotating shaft 15. A crossbar 18 is fixedly connected to the side of the top end of the two swing arms 17. The left and right sides of the crossbar 18 are fixedly connected to the side of the top end of the two swing arms 17. The right rear end of the crossbar 18 contacts the contact plate 6. The bottom end of the crossbar 18 contacts the inner wall of the bottom end of the two grooves 9. An opening 19 is opened at the right top end of the crossbar 18. The inner wall of the opening 19 contacts the outside of multiple shuttles 3.

[0028] In this embodiment, the electric telescopic rod 13 is activated, the drive assembly begins to work, the rack plate 14 drives the gear 16 to rotate, driving the swing arm 17 and the crossbar 18 to move. During this process, on the one hand, the crossbar 18 pushes the probe 5 to detect the position of the shuttle 3; on the other hand, the push rod 4, under the overall coordination of the drive assembly, pushes the shuttle 3 in the placement slot 2 forward. The opening 19 guides and straightens the shuttle 3, ensuring that the shuttle 3 is accurately pushed to the working position. When the shuttle 3 is pushed into place, the probe 5 detects the corresponding position change and feeds it back to the system, the electric telescopic rod 13 stops working, and one shuttle change operation is completed; after the shuttle change is completed, the electric telescopic rod 13 retracts, driving the rack plate 14 back to the initial position, the gear 16 rotates in the opposite direction, and the swing arm 17 and the crossbar 18 also return to the initial position. During this process, the crossbar 18 drives the probe 5 back to the initial detection position, and at the same time, the remaining shuttles 3 in the placement slot 2 are automatically arranged forward under the action of the limiting block 7, filling the position of the pushed-out shuttle 3.

[0029] The working principle and usage process of this utility model are as follows: When the electric telescopic rod 13 is activated, the linear motion of the rack plate 14 is converted into the circular motion of the gear 16. The gear 16 drives the rotating shaft 15 to rotate within the support plate 1. When the rotating shaft 15 rotates, the swing arm 17 swings around the rotating shaft 15 as the center. The swing arms 17 on the two support plates 1 move synchronously. Because the top ends of the two swing arms 17 are fixedly connected to the side of the top end of the two swing arms 17, and the left and right sides of the crossbar 18 are respectively connected to the side of the top end of the two swing arms 17, the movement of the two swing arms 17 can be coordinated. When the crossbar 18 moves with the swing arm 17, it will push the contact plate 6 forward, thereby driving the probe 5 to slide forward in the groove 12 inside the top end of the support plate 1. The sliding of the probe 5 is used to detect the position information of the shuttle 3. During the swing of the crossbar 18, the opening 19 and the auxiliary limiting block 7 further position the shuttle 3 to ensure that the shuttle 3 is neatly arranged. During the shuttle changing process, the opening 19 will guide and straighten the shuttle 3 pushed out by the push rod 4, ensuring that the shuttle 3 can be accurately pushed to the working position.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
