[0037] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0038] The core of this invention is to provide an electric fabric roll release mechanism and a loom, which can realize the automatic release of the fabric roll from the loom, reduce labor intensity, and improve work efficiency.

[0039] To enable those skilled in the art to better understand the technical solutions provided by the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] For details, please refer to Figures 1-7 The present invention provides an electric fabric roll release mechanism, comprising one or two release units, wherein the release unit is detachably connected to the end of the fabric roll of the loom to achieve a limiting position.

[0041] The disengagement unit includes a housing 200, a drive shaft 410, a sliding gear 340, a sliding sleeve 350, a rotating sleeve 360, a fabric roll connecting key 370, and a first driving device. The housing 200 has a first mounting hole 210 and a second mounting hole 220 spaced apart and communicating with each other. One end of the drive shaft 410 is used to connect to the second driving device, and the other end of the drive shaft 410 is inserted into one end of the first mounting hole 210. The other end of the drive shaft 410 is sequentially fitted with the sliding gear 340, the sliding sleeve 350, and the rotating sleeve 360. The transmission end of the first driving device is located at the first... The two mounting holes 220 are connected to the sliding gear 340. One end of the sliding sleeve 350 is connected to the sliding gear 340. The other end of the sliding sleeve 350 is sleeved on one end of the rotating sleeve 360 ​​and is upper limited in the axial direction and movable in the circumferential direction. The other end of the rotating sleeve 360 ​​is provided with a roll-up connecting key 370 for connecting with the roll-up roller. One end of the sliding sleeve 350 is provided with a spirally arranged inclined groove 351. The housing 200 has a first pin hole 211 that matches the inclined groove 351. The inclined groove 351 of the sliding sleeve 350 and the first pin hole 211 of the housing 200 are connected by a first pin 391.

[0042] It should be noted that both the sliding gear 340 and the sliding sleeve 350 are clearance-fitted with the transmission shaft 410 (or can be considered as not being connected to the transmission shaft 410). The sliding gear 340 and the sliding sleeve 350 do not rotate with the rotation of the transmission shaft 410. However, the rotating sleeve 360 ​​is interference-fitted or threaded with the transmission shaft 410 (or can be considered as being connected to the transmission shaft 410). The rotating sleeve 360 ​​can rotate synchronously with the rotation of the transmission shaft 410, and the rotating sleeve 360 ​​can also move axially synchronously with the axial movement of the sliding sleeve 350.

[0043] The sliding gear 340 is axially movable, and the sliding sleeve 350 can move axially while rotating. The rotating sleeve 360 ​​can control axial movement without affecting rotation.

[0044] The first driving device can drive the sliding gear 340 to rotate, and at the same time drive the sliding sleeve 350, the rotating sleeve 360 ​​and the fabric rolling connecting key 370 to reciprocate along the axial direction within the first mounting hole 210. This ultimately enables the fabric rolling connecting key 370 to switch between a first position and a second position (the first position and the second position are the two extreme positions of the fabric rolling connecting key 370 in axial movement). In the first position, the fabric rolling connecting key 370 extends out of the first mounting hole 210 and engages with the end of the fabric rolling roller, thereby enabling the second driving device to drive the transmission shaft 410, the rotating sleeve 360, the fabric rolling connecting key 370 and the fabric rolling roller to rotate normally. In the second position, the fabric rolling connecting key 370 retracts into the first mounting hole 210 and separates from the end of the fabric rolling roller, thereby releasing the limiting relationship between the two.

[0045] This invention provides an electric fabric roll release mechanism. A release unit is provided at least at one end of the fabric roll on a loom. The housing 200 of the release unit has a first mounting hole 210 and a second mounting hole 220. A drive shaft 410, a sliding gear 340, a sliding sleeve 350, and a rotating sleeve 360 ​​are sleeved on the drive shaft 410. The output end of a first driving device is provided in the second mounting hole 220. The sliding sleeve 350 has an inclined groove 351 and is connected to the housing 200 via a first pin 391. The rotating sleeve 360 ​​is axially limited and circumferentially movable with the sliding sleeve 350. The first driving device drives the sliding gear 340 to rotate, simultaneously causing the sliding sleeve 350, the rotating sleeve 360, and the fabric roll connecting key 370 provided on the rotating sleeve 360 ​​to reciprocate circumferentially, allowing the fabric roll connecting key 370 to switch between a locked and unlocked (released) state with the end of the fabric roll.

[0046] By cooperating with each other, the fabric roll can be automatically detached from the loom, which can reduce labor intensity and improve work efficiency.

[0047] In the above embodiments, the first mounting hole 210 and the second mounting hole 220 can be through holes, or the first mounting hole 210 is a through hole and the second mounting hole 220 is a countersunk hole opened on one side of the housing 200; the thickness of the housing 200 where the first mounting hole 210 is located is greater than the thickness of the housing 200 where the second mounting hole 220 is located, so as to better accommodate the components inside the first mounting hole 210. Figure 7 As shown, the housing 200 containing the first mounting hole 210 is a cylindrical body with openings at both ends, and the housing 200 containing the second mounting hole 220 is a rectangular housing 200. The cylindrical body and the rectangular housing 200 can be separate structures or manufactured as a single piece. Both the first mounting hole 210 and the second mounting hole 220 are circular holes.

[0048] There are various ways to achieve the axial upper limit and circumferential movable connection between the rotating sleeve 360 ​​and the sliding sleeve 350. In a specific embodiment, the other end of the sliding sleeve 350 is provided with a second pin hole 352, and one end of the rotating sleeve 360 ​​is provided with an annular groove that matches the second pin hole 352. The second pin hole 352 of the sliding sleeve 350 and the annular groove of the rotating sleeve 360 ​​are connected by a second pin 392 to achieve the axial upper limit and circumferential movable connection between the rotating sleeve 360 ​​and the sliding sleeve 350. Of course, the sliding sleeve 350 and the rotating sleeve 360 ​​can also adopt other structural forms. Any structural improvement that can satisfy the above functions is within the scope of protection of this application and will not be further limited here.

[0049] like Figures 4-6 As shown, both the sliding sleeve 350 and the rotating sleeve 360 ​​can adopt a cylindrical structure with a large-diameter end and a small-diameter end, and their cross-section is T-shaped. The inner hole of the large-diameter end of the sliding sleeve 350 can be fitted onto the outer side of the small-diameter end of the rotating sleeve 360. The end face of the large-diameter end of the rotating sleeve 360 ​​facing the small-diameter end can abut against the end face of the large-diameter end of the sliding sleeve 350, thereby realizing the limiting of the rotating sleeve 360 ​​on the sliding sleeve 350. The second pin hole 352 is opened in the side wall of the large-diameter end of the sliding sleeve 350 and communicates with its inner hole. When the end face of the large-diameter end of the rotating sleeve 360 ​​facing the small-diameter end abuts against the end face of the large-diameter end of the sliding sleeve 350, the second pin hole 352 is exactly in contact with the annular groove 361.

[0050] In a specific embodiment, the first driving device includes a drive motor 310, a drive gear 320, a bridge gear 331, and a bridge gear shaft 332. The housing 200 is provided with a third mounting hole between the first mounting hole 210 and the second mounting hole 220. The bridge gear shaft 332 is provided in the third mounting hole, and the bridge gear 331 is sleeved on the bridge gear shaft 332. The drive gear 320 is provided on the output shaft of the drive motor 310, and the bridge gear 331 meshes with the drive gear 320 and the sliding gear 340 respectively.

[0051] The drive motor 310 can be a servo motor or other rotary power device.

[0052] To facilitate the installation of the bridge gear shaft 332, an internal thread is provided in the third mounting hole, and an external thread that mates with the internal thread is provided at one end of the bridge gear shaft 332.

[0053] Specifically, the other end of the bridge gear shaft 332 is connected to the bridge gear shaft 332 via a bearing 336. The other end of the bridge gear shaft 332 is also provided with a baffle 333 and a retaining ring 335 for the bore to prevent unnecessary axial movement of the bearing 336. At the same time, the baffle 333 also isolates the interior of the bearing 336 from external substances, thereby reducing the possibility of dust, harmful gases and other impurities entering the inner cavity of the bearing 336.

[0054] In a specific embodiment, the two extreme positions of the inclined groove 351 are the two extreme positions of the sliding sleeve 350 in circumferential movement. The two extreme positions are the first position and the second position. In the first position, the fabric winding connecting key 370 is engaged with the fabric winding roller. In the second position, the fabric winding connecting key 370 is disengaged from the fabric winding roller, and at this time the fabric winding connector is retracted into the first mounting hole 210.

[0055] Furthermore, the end face of the housing 200 at the second mounting hole 220 can serve as a limiting surface to prevent the fabric roll from following the movement when the electric fabric roll release mechanism disengages, specifically as follows: Figure 6 The end face of the cylindrical body shown. In the design, in the second position, the outer end face of the fabric winding connection key 370 is exactly flush with the end face of the housing 200 in the second mounting hole 220, thereby realizing the disengagement mechanism and the fabric winding roller disengagement and releasing their limiting relationship.

[0056] To facilitate the installation of the components in the electric fabric roll release mechanism, the output shaft of the drive mechanism and the drive gear 320 are connected by a first screw 321. A second screw 334 is threaded onto the other end face of the bridge gear shaft 332, and the head of the second screw 334 can press the baffle 333 onto the bridge gear shaft 332. The rotating sleeve 360 ​​and the fabric roll connecting key 370 are connected by a third screw 371. The second screw 334 can be a Phillips head screw.

[0057] Meanwhile, in order to make the relative movement of the rotating sleeve 360 ​​and the sliding sleeve 350 smoother, a thrust bearing 336 is provided between the rotating sleeve 360 ​​and the sliding sleeve 350. The purpose of this is that during normal operation, the sliding sleeve 350 is fixed, while the rotating sleeve 360 ​​can rotate under the drive of the transmission shaft 410. The rotating sleeve 360 ​​can achieve normal operation relative to the sliding sleeve 350 and reduce friction and wear through the thrust bearing 336.

[0058] In a specific embodiment, the housing 200 is provided with an oil cup hole 230230 for introducing lubricating oil into the first mounting hole 210. An oil cup 380 can be inserted into the oil cup hole 230230 to lubricate the components inside the first mounting hole 210 of the entire electric fabric roll release mechanism, achieving a good lubrication effect. The oil cup hole 230230 connects to the outside and the first mounting hole 210.

[0059] In one specific embodiment, the entire electric fabric roll release mechanism is fixed to the wall panel 100 through the connecting holes on the housing 200. The servo motor is mounted to the housing 200 with screws, and the drive gear 320 is mounted on the output shaft of the servo motor and secured with a first screw 321. The intermediate gear shaft 332 is directly installed in a threaded hole inside the housing 200. The intermediate gear 331 is assembled with the intermediate gear shaft 332 through a bearing 336, a baffle 333, a second screw 334, and a retaining ring 335.

[0060] The drive shaft 410 is a splined shaft. A sliding gear 340, a sliding sleeve 350, and a rotating sleeve 360 ​​are sequentially movably sleeved on the drive shaft 410. The inner hole of the rotating sleeve 360 ​​is a splined hole, and the splined hole of the rotating sleeve 360 ​​is engaged with the spline on the drive shaft 410.

[0061] The outer circle of the sliding sleeve 350 mates with the first mounting hole 210 of the housing 200, allowing it to rotate and move axially within the first mounting hole 210. The sliding gear 340 is mounted on the end face of the sliding sleeve 350 by screws and moves with the sliding sleeve 350. The outer circle of the rotating sleeve 360 ​​mates with the inner hole of the sliding sleeve 350. A second pin 392 is mounted on the outer circle of the sliding sleeve 350, and the second pin 392 also mates with the annular groove 361 of the rotating sleeve 360, allowing the rotating sleeve 360 ​​to rotate freely, but its axial movement is restricted by the sliding sleeve 350. The fabric winding connecting key 370 is installed in the mounting groove 362 of the rotating sleeve 360, serving the same purpose as the rotating sleeve 360 ​​in positioning the fabric winding roller and transmitting power to it. The housing 200 has a first pin hole 211, in which the first pin 391 is installed. Figure 4 As shown, the other end of the first pin 391 is inserted into the inclined groove 351 of the sliding sleeve 350.

[0062] The overall appearance of the mechanism is as follows Figure 1As shown, when fabric needs to be dropped, the program controls the servo motor to rotate. Power is transmitted to the sliding gear 340 through the drive gear 320, the bridge gear shaft 332, and the bridge gear 331. The sliding gear 340 drives the sliding sleeve 350 to rotate. Since the sliding sleeve 350 is provided with an inclined groove 351, which cooperates with the fixed first pin 391, the sliding sleeve 350 moves left and right while rotating, thereby driving the rotating sleeve 360 ​​and the fabric winding connecting key 370 to move axially, so that this sleeve mechanism is disengaged from the fabric winding roller. When the new fabric winding roller is reinstalled, the program controls the servo motor to rotate in the opposite direction. The same principle drives the rotating sleeve 360 ​​and the fabric winding connecting key 370 to rotate in the opposite direction, thus locking the fabric winding roller again.

[0063] In addition, the present invention also provides a loom, including a wall panel 100, a fabric roll, a second drive device, and the electric fabric roll release mechanism in the above specific embodiments.

[0064] The wall panel 100 is connected to the housing 200 of the electric fabric roll release mechanism. The fabric roll connection key 370 of the electric fabric roll release mechanism is used to connect to the end of the fabric roll. The drive shaft 410 of the electric fabric roll release mechanism passes through the wall panel 100 and is connected to the output shaft of the second drive device.

[0065] The second drive unit is used to drive the transmission shaft 410 of the electric fabric roll release mechanism to rotate, and simultaneously drive the rotating sleeve 360, the fabric roll connecting key 370, and the fabric roll to rotate. The first drive unit is activated when the fabric roll needs to be disassembled or assembled, and the second drive unit is activated when the fabric roll is being driven to work normally.

[0066] The aforementioned loom types can be adapted to different textile needs, such as rapier looms, air-jet looms, and water-jet looms. Each type of loom has different characteristics. Rapier looms use rigid or flexible rapier heads to hold and guide the weft yarn. These looms are suitable for fabrics with a large variety of coarse yarns. Air-jet looms use compressed air jets to pull the weft yarn through the shed. The fabrics produced by these looms are generally made of fine yarns. Water-jet looms use jets of water to pull the weft yarn through the shed, thus completing the weaving process. These looms are better suited to the weft insertion requirements of smooth-surfaced synthetic fibers, glass fibers, and other materials.

[0067] When the complete electric fabric roll release mechanism includes two release units, the two release units are respectively installed on the inner side of the left and right wall panels 100 by screws or other fasteners. The two ends of the fabric roll are connected to the release units on their corresponding sides.

[0068] When the entire electric fabric roll release mechanism contains only one release unit, the release unit is installed inside one side wall panel 100 by fasteners such as screws. One end of the fabric roll is connected to its corresponding release unit, and the output shaft of the second drive mechanism on that side drives the fabric roll to rotate. The other end is connected to the other end of the fabric roll through a rotating component in the prior art to achieve driven rotation.

[0069] That is, such as Figure 2 The image shows an electrically operated fabric roll release mechanism located on the power side of the fabric roll. The drive shaft 410 can be a splined shaft.

[0070] The purpose of this invention is to reduce labor intensity, bring looms closer to automation and intelligence, and lay the foundation for intelligent manufacturing of looms.

[0071] Obviously, looms that include the above-mentioned electric roll release mechanism have the same beneficial effects, which will not be elaborated further here.

[0072] In order to make the rotation of the drive shaft 410 more stable and smooth, the wall plate 100 is provided with a bearing seat 420 on the side away from the housing 200, and the drive shaft 410 is disposed in the bearing seat 420.
