Description

Technical Field

[0001] This utility model relates to the field of circular knitting machine technology, specifically to a fabric winding device for a circular knitting machine. Background Technology

[0002] Circular knitting machines, also known as circular weft knitting machines, have developed rapidly and gained widespread use due to their numerous loop-forming systems, high speed, high output, rapid pattern changes, good fabric quality, fewer processes, and strong product adaptability.

[0003] The knitting mechanism of the circular knitting machine weaves the fabric. The woven fabric is held and pulled by the two roll rollers of the roll machine's traction device. After being guided, the fabric is wound onto the take-up roller of the roll machine to form a roll.

[0004] The inventors of this application have discovered that currently, the two ends of the take-up roller shaft of a fabric rolling machine are placed directly in the U-shaped groove of the frame. When the fabric roll reaches the maximum preset diameter, the machine is shut down, and then manual assistance is required to lift the fabric roll off the frame. Since the fabric roll can weigh approximately 150 kg when it reaches the preset maximum diameter, lifting the fabric roll off the frame is quite difficult, inconvenient, and poses a safety hazard.

[0052] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0053] As described in the background section of this application, the knitting mechanism of a circular knitting machine weaves fabric. The woven fabric is held and pulled by two roll rollers of the roll-up machine's traction device. After being guided, the fabric is wound onto the take-up roller shaft of the roll-up machine to form a roll.

[0054] The inventors of this application have discovered that currently, the two ends of the take-up roller shaft of a fabric rolling machine are placed directly in the U-shaped groove of the frame. When the fabric roll reaches the maximum preset diameter, the machine is shut down, and then manual assistance is required to lift the fabric roll off the frame. Since the fabric roll can weigh approximately 150 kg when it reaches the preset maximum diameter, lifting the fabric roll off the frame is quite difficult, inconvenient, and poses a safety hazard.

[0055] To address the aforementioned problems, the inventors of this application have proposed a technical solution, the specific embodiments of which are as follows:

Figure 9 As described in the embodiments of this utility model Figure 7 Another enlarged view of a portion of the image.

[0057] like Figures 1 to 9 As shown, the fabric winding device of the large circular knitting machine in this embodiment is set on the frame 1 of the fabric winding machine. The fabric winding device includes: a drive motor 21, a rubber roller shaft 22, a core 3 and a clamping mechanism 4.

[0058] The drive motor 21 is mounted on the frame 1 of the fabric rolling machine and is electrically connected to the machine's controller.

[0059] Two rubber roller shafts 22 are provided, which are arranged in parallel intervals and are horizontally positioned. The two ends of the rubber roller shafts 22 are rotatably mounted on the frame 1 through bearings. The rubber roller shafts 22 are connected to the drive motor 21 for transmission, and the drive motor 21 is used to drive the rubber roller shafts 22 to rotate.

[0060] The clamping mechanism 4 is provided in two sets, which are set on the frame 1 and respectively corresponding to the two ends of the rubber roller shaft 22.

[0061] The clamping mechanism 4 includes: a fixed plate 41, a guide rail plate 42, and a handle 43.

[0062] The fixed plate 41 is vertically fixed on the frame 1, and the bottom end of the guide rail plate 42 is rotatably mounted on the frame 1 via a pivot. One end of the handle 43 is rotatably mounted on the fixed plate 41 via a pivot, located at the top of the fixed plate 41. When the handle 43 is closed, it forms a movable connection with the guide rail plate 42, so that the guide rail plate 42 is vertically fixed on the frame 1. When the guide rail plate 42 is fixed, there is a certain distance between the guide rail plate 42 and the fixed plate 41, and the guide rail plate 42 is located on the outside of the frame 1 and can be flipped to the outside of the frame 1.

[0063] The side walls of the fixed plate 41 and the guide rail plate 42 are provided with limiting guide grooves 401.

[0064] The core 3 includes: a take-up roller 31, a take-up paper tube 32, and a bearing 33.

[0065] The length of the take-up roller shaft 31 is greater than the length of the take-up paper tube 32. The take-up roller shaft 31 is inserted into the take-up paper tube 32, and two bearings 33 are respectively sleeved on both ends of the take-up roller shaft 31.

[0066] The take-up paper tube 32 of the core 3 is placed on two rubber roller shafts 22, and the bearings 33 at both ends of the take-up roller shaft 31 are slidably locked in the limiting guide grooves 401 of the fixing plate 41 and the guide rail plate 42. When the handle 43 is closed, the fixing plate 41 and the guide rail plate 42 clamp the bearings 33. The rubber roller shafts 22 provide support for the take-up paper tube 32, and after the take-up paper tube 32 is wound up to form the fabric roll 100, the rubber roller shafts 22 provide support for the fabric roll.

[0067] In this embodiment, the fabric woven by the circular knitting machine is guided by the guide roller and then conveyed and wound onto the take-up paper tube 32.

[0068] The take-up paper tube 32 of the core 3 is placed on two rubber roller shafts 22. When the drive motor drives the rubber roller shafts 22 to rotate, under the action of friction, the rubber roller shafts 22 drive the take-up paper tube 32 and the take-up roller shaft 31 to rotate. When the take-up paper tube 32 rotates, it winds up the fabric to form a fabric roll 100. Then the rubber roller shafts 22 drive the fabric roll 100 to rotate to continue winding. During the winding process, as the diameter of the fabric roll 100 continues to increase, the bearing 33 moves upward along the limiting guide groove 401 of the fixed plate 41 and the guide rail plate 42.

[0069] When the diameter of the fabric roll 100 reaches the set value, the machine and drive motor stop, and the rubber roller shaft 22 stops rotating. Then, lift the handle 43 by hand to separate the handle 43 from the guide plate 42, rotate the guide plate 42 to place it flat on the outside of the frame, and push the fabric roll 100 out from the two rubber roller shafts 22, so that the fabric roll 100 rolls onto the moving trolley, thus completing the take-up of the fabric roll 100.

[0070] As can be seen from the above, the fabric winding device of the large circular knitting machine in this embodiment is equipped with a drive motor, rubber roller shafts, a core, and clamping mechanisms. Two rubber roller shafts are arranged in parallel intervals and connected to the drive motor. Two sets of clamping mechanisms are respectively set at both ends of the rubber roller shafts. The clamping mechanisms include: a fixed plate, a guide rail plate, and a handle. The guide rail plate is rotatably mounted on the frame, and the handle is mounted on the fixed plate. The core includes: a take-up roller shaft, a take-up paper tube, and bearings. The take-up roller shaft passes through the take-up paper tube, and the bearings are located at both ends of the take-up roller shaft. In the fabric winding device of the large circular knitting machine in this embodiment, the take-up paper tube is placed on the two rubber roller shafts, and the bearings are clamped in the limiting guide grooves of the fixed plate and the guide rail plate. The guide rail plate is fixed by the handle. When the rubber roller shaft rotates, it drives the take-up paper tube and the resulting fabric roll to rotate. When the fabric roll diameter reaches the maximum set value, the machine stops. Then, lift the handle by hand and rotate the lower guide plate to roll the fabric roll from the two rubber roller shafts onto the moving trolley, thus completing the take-up of the fabric roll. This is convenient, labor-saving, and ensures safety.

[0071] Optionally, the fabric winding device of the large circular knitting machine in this embodiment further includes: a first sensor 51.

[0072] The first sensor 51 is mounted on the fixed plate 41 of the clamping mechanism 4 and is used to send a signal when the bearing 33 is detected to have reached a preset position.

[0073] In this embodiment, the take-up paper tube of the fabric core is placed on two rubber roller shafts. When the rubber roller shafts rotate, they drive the take-up paper tube to rotate, and the take-up paper tube is wound up to form a fabric roll. As the diameter of the fabric roll gradually increases, the take-up roller shaft and the bearing gradually rise along the limiting guide grooves of the fixed plate and the guide rail plate. When the diameter of the fabric roll reaches the maximum preset value, the first sensor contacts and senses the bearing. The first sensor sends a signal to the controller of the equipment, and the controller controls the equipment and the drive motor to stop automatically to ensure the safe operation of the equipment. Then, the operator pushes the fabric roll (core) off the rubber roller shaft, replaces it with a new core, and can continue working.

[0074] Optionally, in this embodiment, the fabric winding device of the circular knitting machine has a locking groove 431 on the handle 43.

[0075] The top of the guide rail plate 42 is provided with a locking shaft 421. By rotating the handle 43 and the guide rail plate 42, the locking shaft 421 of the guide rail plate 42 is inserted into the locking groove 431 of the handle 43, and the guide rail plate 42 and the handle 43 are locked together. The handle 43 fixes the guide rail plate 42 to the frame 1. When the guide rail plate 42 is fixed, the guide rail plate 42 cooperates with the fixing plate 41 to clamp the bearing 33 of the core 3, so that the core 3 can be fixed to the frame 1 with vertical movement.

[0076] Furthermore, in this embodiment, the fabric winding device of the large circular knitting machine, the clamping mechanism 4, also includes a locking spring 44.

[0077] One end of the locking spring 44 is fixed to the handle 43, and the other end of the locking spring 44 is provided with a locking hook 441.

[0078] The frame 1 is equipped with a latch 11, which is used to engage with the hook 441 to tighten the handle 43.

[0079] In this embodiment, after the locking shaft of the guide rail plate is embedded in the locking groove of the handle and the guide rail plate is fixed, the locking spring is pulled so that the locking hook of the locking spring is engaged with the locking buckle of the guide rail plate. At this time, the locking spring pulls the handle tight, so that the handle is pressed against the guide rail plate to prevent the locking shaft of the guide rail plate from falling out of the locking groove of the handle.

[0080] Furthermore, such as Figure 3 , Figure 5 As shown, the fabric winding device of the large circular knitting machine in this embodiment also includes: a limiting block 6.

[0081] The limiting block 6 is U-shaped. One side of the limiting block 6 is fixed on the frame 1, and the other side of the limiting block 6 is provided with a limiting edge 61.

[0082] The top of the guide plate 42 is provided with a slot 422, the width of which corresponds to the thickness of the limiting edge 61 of the limiting block 6. When the guide plate 42 is in the fixed state, the limiting edge 61 of the limiting block 6 is inserted into the slot 422 of the guide plate 42, so that the guide plate 42 is limited and fixed in the axial direction of the take-up roller shaft 22, preventing the guide plate 42 from swinging or shaking in the axial direction of the take-up roller shaft 22 due to its excessive length.

[0083] Furthermore, the fabric winding device of the large circular knitting machine in this embodiment also includes: a second sensor 52.

[0084] The second sensor 52 is mounted on the frame 1 and located at the bottom of the guide rail plate 42.

[0085] The bottom root of the guide rail plate 42 is provided with a protrusion 423. When the locking shaft 421 of the guide rail plate 42 is embedded in the locking groove 431 of the handle 43 and the guide rail plate 42 is fixed, the second sensor 52 contacts and senses the protrusion 423 of the guide rail plate 42. The second sensor 52 sends a signal to the equipment controller, and the machine and drive motor can start to operate, ensuring the safe operation of the machine.

[0086] Optional, such as Figure 3 and Figure 6 As shown, in this embodiment, the fabric winding device of the large circular knitting machine has a notch 12 on the side plate of the frame 1.

[0087] One end of the handle 43 is rotatably mounted on the fixed plate 41, and the other end of the handle 43 is mounted in the notch 12 of the frame 1. The two sides of the notch 12 of the frame 1 limit the handle 43 to restrict the rotation angle of the handle 43, making it more convenient to use.

[0088] Optional, such as Figure 7 , Figure 8 and Figure 9 As shown, the fabric winding device of the large circular knitting machine in this embodiment further includes: a paper tube end support sleeve 34 and a paper tube center support sleeve 35.

[0089] The paper tube end support sleeve 34 and the paper tube center support sleeve 35 are sleeved on the take-up roller shaft 31, located at both ends of the take-up roller shaft 31 respectively, and are fixed by the fixing screw 36.

[0090] The paper tube end support sleeve 34 is provided with a limiting step 341. The winding paper tube 32 is sleeved on the paper tube end support sleeve 34 and the paper tube center support sleeve 35, so that the central axis of the winding paper tube 32 coincides with the central axis of the take-up roller shaft 31 (concentric); and the end face of the winding paper tube 32 abuts against the step shoulder of the limiting step 341 of the paper tube end support sleeve 34, so as to prevent the winding paper tube 32 (cloth roll) from shifting during the operation of the equipment.

[0091] Furthermore, the paper tube end support sleeve 34 is located at one end of the take-up roller shaft 31, which facilitates the take-up roller shaft 31 to be pulled out from the take-up paper tube 32 (cloth roll) to replace the new take-up paper tube 32.

[0092] Furthermore, such as Figure 2 and Figure 6 As shown, the fabric winding device of the large circular knitting machine in this embodiment further includes: a winding table 7.

[0093] The receiving platform 7 is set on the frame 1, located outside the rubber roller shaft 22, and is used to receive the cloth roll 100.

[0094] The outer top surface of the receiving platform 7 is provided with an inclined surface 71 to restrict the rolling of the fabric roll.

[0095] In this embodiment, when the fabric roll reaches the maximum preset diameter, the handles on both sides are opened, the guide rail plate is lowered, and then the fabric roll is first rolled from the rubber roller shaft onto the receiving platform, and then rolled onto the moving trolley, making the receiving more convenient.

[0097] Furthermore, "above," "on top of," and "above" the first feature in relation to the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "under," and "beneath" the first feature in relation to the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
