Description

Technical Field

[0001] This utility model relates to the field of fabric winding technology, and in particular to a fabric winding device for a water jet loom. Background Technology

[0002] Water jet looms are shuttleless looms that use jets of water to guide the weft yarn through the shed. Water jet weft insertion provides greater frictional traction on the weft yarn than air jet weft insertion, with less diffusion, making it suitable for weft insertion of smooth-surfaced synthetic fibers, glass fibers, and other filaments. It also increases the electrical conductivity of synthetic fibers, effectively overcoming static electricity during weaving. Furthermore, water jet weft insertion consumes less energy and produces the lowest noise levels.

[0003] A patent website discloses a fabric unwinding and rewinding device for a water jet loom (CN 222476909 U), which facilitates quick unloading and disassembly of the rolled fabric. It includes a base plate and further comprises a winding mechanism, an adjusting mechanism, an auxiliary mechanism, a disassembly mechanism, a drive mechanism, and a transmission mechanism. The adjusting mechanism is mounted on the winding mechanism, the auxiliary mechanism is mounted on the adjusting mechanism, the disassembly mechanism is mounted on the winding mechanism, the drive mechanism is mounted on the winding mechanism, and the transmission mechanism is mounted on the drive mechanism. The auxiliary mechanism assists the adjusting mechanism in driving the winding mechanism to unload the wound fabric. The transmission mechanism drives the winding mechanism to rotate, thereby driving the auxiliary mechanism to wind up the fabric.

[0004] As can be seen from the above technology, most of the existing water jet looms use a single take-up mechanism when winding up the fabric. Since the water jet loom produces fabric at a constant speed, the loom needs to be stopped when changing the take-up mechanism, and it can only resume operation after the take-up mechanism has been changed. This results in low work efficiency, and there is room for improvement. Utility Model Content

[0005] This invention provides a fabric output and take-up device for a water jet loom to solve the problems mentioned in the background art.

[0006] To address the aforementioned problems, this utility model provides a fabric output and take-up device for a water jet loom, comprising a base and a take-up roller. The base is U-shaped, with a first mounting plate rotatably mounted on the left side and a second mounting plate rotatably mounted on the right side. A first motor for driving the first mounting plate to rotate is located within the left frame of the base. Two U-shaped positioning seats are symmetrically rotatably connected to the first and second mounting plates, respectively. Two take-up rollers are mounted between the first and second mounting plates via the positioning seats. An insert plate that abuts against the end of the take-up roller is inserted into the positioning seat. Two positioning holes are symmetrically opened on the outer end of the insert plate. A positioning mechanism for inserting the positioning holes is provided on the outer side of the positioning seat. The end of the positioning seat in the second mounting plate rotatably passes through the second mounting plate and is fixedly provided with a plug at the end. A slide is mounted on the right side of the base, and a sliding frame is slidably connected to the slide. A second motor is mounted in the sliding frame, and a plug for connecting the plug is installed in the power output shaft of the second motor.

[0007] Preferably, the positioning mechanism consists of a first sliding plate, a second sliding plate, positioning rods, and a spring. The first and second sliding plates are fixedly mounted vertically on the side of the positioning seat and located above the insert plate. There are two positioning rods that slide through the first and second sliding plates and are inserted into the positioning holes in the insert plate. A limiting ring is fixed in the positioning rod and moves against the upper surface of the second sliding plate. A positioning plate is fixed at the top between the two positioning rods, and a handle is installed in the positioning plate. The spring is sleeved in the positioning rod and located between the limiting ring and the first sliding plate.

[0008] Preferably, the right side frame of the base is provided with an electric push rod that drives the sliding frame to move in the slide.

[0009] Preferably, the outer opening of the connector is a conical surface, and a positioning groove is provided inside the connector. The plug has an installation groove, and a positioning block that matches the positioning groove is slidably connected inside the installation groove. Two springs are symmetrically installed between the bottom of the positioning block and the installation groove. The front side of the positioning block has a wedge-shaped surface that matches the conical surface.

[0010] The beneficial effects of adopting the above technical solutions are:

[0011] The first motor drives the first mounting plate to rotate, which in turn causes the two take-up rollers to rotate in the base in conjunction with the second mounting plate. This allows the take-up rollers to rotate, making it easy to use the two take-up rollers alternately. The take-up rollers can be replaced without stopping the machine, thus improving work efficiency.

[0012] The sliding block, sliding frame, and electric push rod can drive the second motor to move. In conjunction with the plug in the second motor and the plug-in seat at the end of the positioning seat, the take-up roller can be easily driven by the second motor after its position is changed, and it is also easy to position the take-up roller after its position is changed.

[0013] The U-shaped positioning seat, insert plate, and positioning mechanism facilitate the loading and unloading of the take-up roller. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, a movable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium.

[0024] like Figure 1-6 In this embodiment, a fabric take-up device for a water-jet loom includes a base 1 and a take-up roller 2. The base 1 is U-shaped, with a first mounting plate 3 rotatably mounted on the left side and a second mounting plate 4 rotatably mounted on the right side. A first motor 31 for driving the first mounting plate 3 to rotate is located in the left frame of the base 1. Two U-shaped positioning seats 5 are symmetrically rotatably connected to the first mounting plate 3 and the second mounting plate 4, respectively. There are two take-up rollers 2, which are mounted between the first mounting plate 3 and the second mounting plate 4 via the positioning seats 5. The positioning seats 5 are inserted with... An insert plate 51 is attached to the end of the take-up roller 2. Two positioning holes 52 are symmetrically opened on the outer side of the insert plate 51. A positioning mechanism 6 is provided on the outer side of the positioning seat 5 to pass through the positioning holes 52. The end of the positioning seat 5 in the second mounting plate 4 rotates through the second mounting plate 4 and is fixedly provided with a plug-in seat 7. A slide 81 is installed on the right side frame of the base 1, and a slide frame 82 is slidably connected in the slide 81. A second motor 8 is installed in the slide frame 82, and a plug 83 for plugging into the plug-in seat 7 is installed in the power output shaft of the second motor 8.

[0025] Through the above technical solution, when the upper take-up roller 2 of the two take-up rollers 2 between the first mounting plate 3 and the second mounting plate 4 is fully wound with fabric, the second motor 8, in conjunction with the sliding frame 82, slides on the slide block 81, causing the plug 83 to disengage from the insertion seat 7, thereby releasing the restriction on the second mounting plate 4. At this time, the first motor 31 drives the first mounting plate 3, in conjunction with the second mounting plate 4, to cause the take-up roller 2 to flip. The take-up roller 2 fully wound with fabric moves to the lower position, and the lower take-up roller 2 moves to the upper position. Then, by moving the second motor 8, the plug 83 is inserted into the insertion seat 7, thereby limiting the second mounting plate 4 and facilitating the rotation of the positioning seat 5. The movement causes the take-up roller 2 to rotate and take up the fabric. Then, by unlocking the positioning mechanism 6 and the insert plate 51, the take-up roller 2, which is full of fabric, can be taken out. Since the positioning seat 5 is U-shaped, the take-up roller 2, which is full of fabric, can be taken out after the insert plate 51 is pulled out. Then, the empty take-up roller 2 is placed in the positioning seat 5 in the first mounting plate 3 and the second mounting plate 4. The insert plate 51 is then inserted and, together with the positioning mechanism 6, the insert plate 51 is limited so that it abuts against the end of the take-up roller 2 and positions it in the positioning seat. This completes the replacement of the take-up roller 2, ensuring the continuity of work and effectively improving work efficiency.

[0026] Preferably, the positioning mechanism 6 consists of a first sliding plate 61, a second sliding plate 62, a positioning rod 63, and a spring 64. The first sliding plate 61 and the second sliding plate 62 are fixedly mounted vertically on the side of the positioning seat 5 and are located above the insert plate 51. There are two positioning rods 63, which slide through the first sliding plate 61 and the second sliding plate 62 and are inserted into the positioning holes 52 in the insert plate 51. A limiting ring 631 that abuts against the upper surface of the second sliding plate 62 is fixed in the positioning rod 63. A positioning plate 65 is fixed at the top between the two positioning rods 63, and a handle 651 is installed in the positioning plate 65. The spring 64 is sleeved in the positioning rod 63 and is located between the limiting ring 631 and the first sliding plate 61.

[0027] Through the above technical solution, when positioning and releasing the insert plate 51, the handle 651 pulls the positioning plate 65, causing the two positioning rods 63 to move upward, thereby disengaging from the positioning hole 52 in the insert plate 51 and releasing the restriction on the insert plate 51. Then, the insert plate 51 is pulled out from the positioning seat 5, which releases the restriction on the end of the take-up roller 2, thus facilitating the replacement of the take-up roller 2. When the end of the take-up roller 2 is placed in the positioning seat 5, the positioning plate 65 is pulled to raise the two positioning rods 63, and then the insert plate 51 is inserted into the positioning seat 5. At this time, the handle 651 is released, and under the action of the spring 64, the limiting ring 631 causes the positioning rods 63 to move downward, thereby inserting into the positioning hole 52 and firmly limiting the insertion plate 51. This ensures that the insert plate 51 can stably press the end of the take-up roller 2 in the positioning seat 5, improving the work efficiency of replacing the take-up roller 2.

[0028] Preferably, the right side frame of the base 1 is provided with an electric push rod 84 that drives the sliding frame 81 to move in the slide block 82.

[0029] Through the above technical solution, the electric push rod 84 is used to push the sliding frame 82 to slide stably on the slide block 81, thereby enabling the second motor 8 to move and ensuring the stability of the insertion and removal between the plug 83 and the socket 7.

[0030] Preferably, the outer opening of the plug-in 7 is a conical surface 71, and a positioning groove 72 is provided inside the plug-in 7. The plug 83 has an installation groove 831, and a positioning block 832 matching the positioning groove 72 is slidably connected inside the installation groove 831. Two springs 833 are symmetrically installed between the bottom of the positioning block 832 and the installation groove 831. The front side of the positioning block 832 has a wedge-shaped surface 834 matching the conical surface 71.

[0031] Through the above technical solution, the movement of the second motor 8 facilitates the engagement and disengagement of the plug 83 and the socket 7. When engaged, the movement of the second motor 8 causes the plug 83 to be inserted into the socket 7. Since the outer opening of the socket 7 is a conical surface 71, a positioning block 832 is slidably connected in the plug 83, and a wedge-shaped surface 834 is provided on the front side of the positioning block 832. When the positioning block 832 moves to the conical surface 71, it is pressed and then retracts into the mounting groove 831. After the plug 83 is fully inserted into the socket 7, the second motor 8 rotates. When the positioning block 832 aligns with the positioning groove 72, under the action of the spring 833, the positioning block 832 pops out from the mounting groove 831 and thus locks into the positioning groove 72. This allows the second motor 8 to drive the socket 7 to rotate, thereby cooperating with the positioning seat 5 to drive the take-up roller 2 to rotate. When the second motor 8 moves backward, the positioning block 832 slides along the positioning groove 72, thereby ensuring that the plug 83 can be pulled out from the socket 7.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate this utility model and are not intended to limit the technical solutions described in this utility model. Therefore, although this specification has described this utility model in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to this utility model, and all technical solutions and improvements that do not depart from the spirit and scope of this utility model should be covered within the scope of the claims of this utility model; technologies not described in detail in this utility model are implemented using existing technologies.
