Description

Technical Field

[0001] The utility model belongs to the technical field of jacquard machines, and in particular relates to a turning mechanism of a jacquard machine. Background Art

[0002] As a weaving tool, the jacquard loom is an important invention in ancient China. According to archaeological evidence, from the traces of silk fabrics preserved on the bronze vessels in the tombs of Yinxu in Anyang, Henan, there are not only plain weave silk but also jacquard diamond weave silk. This shows that it appeared in my country as early as the Shang Dynasty. Ordinary looms can only weave plain weave fabrics, and fabrics with complex patterns can only be woven by jacquard looms.

[0003] After the existing jacquard machine is installed, the entire machine body may not be able to remain level with the ground. The uneven machine body will lead to poor working stability and stronger vibration, thereby affecting the service life of the jacquard machine parts.

[0004] The existing patent (application number: CN201621027486.9) proposes an efficient and safe jacquard machine, including a frame, a support plate body installed on the frame, a knife lifting frame installed on the support plate body, a jacquard needle installed on the knife lifting frame, and a driving device arranged on the frame for driving the knife lifting frame to operate. The frame has support legs, and a spiral leveling knob is provided at the bottom of the support leg. A tray is provided on the bottom surface of the frame. The overall structure is simple, safe to use, and is conducive to wide promotion and application.

[0005] When the existing jacquard machine is in use, it is usually only possible to jacquard one side of the jacquard fabric. When the other side needs to be jacquard, the jacquard fabric needs to be re-clamped, which makes it difficult to quickly turn the jacquard fabric over and ensure the neatness of the jacquard fabric after turning over, making it inconvenient to use.

[0006] In view of this, this application is hereby filed. Utility Model Content

[0007] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a jacquard machine turnover mechanism to achieve the desired purpose.

[0008] In order to solve the above technical problems, the utility model provides a jacquard machine turning mechanism, comprising:

[0009] A positioning component for fixing the fabric;

[0010] A turning assembly for driving the fabric to turn over;

[0011] The cam is secured to the upper and lower surfaces of the frame and is adapted to engage with the gears of the drive means and to engage with the gears of the drive means to engage with the gears of the drive means.

[0012] Furthermore, the positioning assembly also includes a support seat fixedly mounted on the front end face of the lower frame, a movable seat is rotatably mounted on the support seat, the movable seat is an L-shaped structure, one end of the long side of the movable seat is rotatably connected to the support seat, an adjusting bolt is threadedly connected on the short side of the movable seat, and a clamping plate is rotatably connected to the bottom end of the adjusting bolt.

[0013] Furthermore, a connecting seat is fixedly mounted on the rear end surface of the lower frame body, a hinge piece is rotatably mounted on the connecting seat, and the hinge piece is fixedly connected to the rear end surface of the upper frame body.

[0014] Furthermore, a flexible pad is installed on the mutually contacting side of the lower frame and the upper frame, the flexible pad is made of rubber, and an anti-slip pattern is integrally formed on the outer surface of the flexible pad.

[0015] Furthermore, a sliding groove is provided on the top surface of the fixed rail, a sliding block is slidably connected inside the sliding groove, and the sliding seat is fixedly connected to the top surface of the sliding block.

[0016] Furthermore, the first limit member is fixedly mounted on the side wall at one end of the fixed rail, and the second limit member is fixedly mounted on the side wall at the other end of the fixed rail. The first limit member and the second limit member are arranged in mirror symmetry, and linkage grooves are provided on both the first limit member and the second limit member.

[0017] After adopting the above technical scheme, the utility model has the following beneficial effects compared with the prior art.

[0018] 1. In the utility model, the upper frame can be conveniently rotated and overlapped on the top surface of the lower frame by the provided connecting seat and hinged sheet, so as to facilitate the pressing and fixing of the fabric. The movable seat can be rotated on the lower frame by the provided supporting seat, so as to facilitate the rotation of the movable seat to the upper surface of the upper frame, and then the movable seat can be moved along the movable seat by rotating the adjusting bolt. The adjusting bolt can push the clamping plate to press the upper frame against the lower frame, thereby improving the stability of fixing the fabric. At the same time, the flexible pad provided between the lower frame and the upper frame can increase the friction between the lower frame, the upper frame and the fabric, thereby further improving the stability of fixing the fabric.

[0019] 2. In the utility model, the servo electric cylinder drives the sliding seat to slide on the fixed rail, and the sliding process of the sliding seat drives the transmission gear to move synchronously. Since the transmission gear and the teeth are on the same axis at this time, when the transmission gear moves to the tooth position, the meshing of the transmission gear and the teeth can drive the transmission gear to drive the connecting shaft to rotate, and the connecting shaft drives the lower frame and the upper frame to flip 180 degrees as a whole. As the servo electric cylinder continues to pull the sliding seat to move, the second limiter will push the transmission pin to move laterally along the straight notch, and the movement of the straight notch drives the drive frame to slide to the outside of the through hole. The driving frame can push the transmission gear to move away from the sliding seat, and then the servo electric cylinder is used to push the sliding seat to reset. Due to the push of the driving frame, the transmission gear and the teeth are not on the same axis, so that the transmission gear avoids the teeth during the resetting of the sliding seat, so that the transmission gear does not rotate. When the sliding seat returns to its initial position, the transmission pin slides and resets along the straight notch under the transmission of the first limiter, and the straight notch drives the driving frame, the transmission gear and the connecting shaft to reset synchronously, so as to achieve the effect of turning over the fabric. The structure is simple, the operation is convenient, and the jacquard efficiency of the fabric is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] A positioning component for fixing the fabric;

[0034] A turning assembly for driving the fabric to turn over;

[0035] The positioning assembly includes a lower frame 1 and an upper frame 2 rotatably superimposed thereon, the flipping assembly includes a fixed rail 10 installed on the jacquard machine and a connecting shaft 13 fixedly connected to the middle part of the rear end surface of the lower frame 1, the fixed rail 10 is slidably connected to a sliding seat 11, the connecting shaft 13 is slidably inserted into the interior of the sliding seat 11, a servo electric cylinder 12 for driving the sliding seat 11 to slide horizontally is fixedly installed on the side wall of the fixed rail 10, a transmission gear 14 is fixedly connected to the end of the connecting shaft 13 away from the lower frame 1, teeth 15 are arranged on the top surface of the fixed rail 10, a first limit member 16 and a second limit member 17 are fixedly installed on the fixed rail 10, a through hole 18 is opened on the sliding seat 11, a driving frame 20 for controlling the forward and backward movement of the transmission gear 14 is slidably connected inside the through hole 18, a straight slot 19 connected to the through hole 18 is opened on the top surface of the sliding seat 11, a transmission pin 21 is slidably connected inside the straight slot 19, and the bottom end of the transmission pin 21 is fixedly connected to the upper surface of the driving frame 20.

[0036] In the utility model, the fabric is placed on the top surface of the lower frame 1, and then the upper frame 2 is rotated and covered on the lower frame 1. The fabric can be clamped and fixed by the cooperation of the lower frame 1 and the upper frame 2, and then the jacquard machine is used to perform jacquard processing on the fabric. After the jacquard on one side of the fabric is completed, the servo electric cylinder 12 drives the sliding seat 11 to slide on the fixed rail 10. During the sliding process of the sliding seat 11, the transmission gear 14 is driven to move synchronously. Since the transmission gear 14 and the teeth 15 are on the same axis at this time, when the transmission gear 14 moves to the position of the teeth 15, the meshing of the transmission gear 14 and the teeth 15 can drive the transmission gear 14 to drive the connecting shaft 13 to rotate, and the connecting shaft 13 drives the lower frame 1 and the upper frame 2 to flip 180 degrees as a whole. As the servo electric cylinder 12 continues to pull the sliding seat 11 to move, the second limit member 1 7 will push the transmission pin 21 to move laterally along the straight notch 19, and the movement of the straight notch 19 drives the driving frame 20 to slide toward the outside of the through hole 18, and the driving frame 20 can push the transmission gear 14 to move away from the sliding seat 11, and then use the servo electric cylinder 12 to push the sliding seat 11 to reset.

When the sliding seat 11 returns to the initial position, the transmission pin 21 slides and resets along the straight notch 19 under the transmission of the first limiter 16, and the straight notch 19 drives the driving frame 20, the transmission gear 14 and the connecting shaft 13 to reset synchronously, so as to achieve the effect of turning over the fabric. The structure is simple, the operation is convenient, and the jacquard efficiency of the fabric is improved.

The first limit member 16 and the second limit member 17 are arranged in mirror symmetry, and linkage grooves are provided on the first limit member 16 and the second limit member 17.

[0042] In the present invention, the linkage grooves provided on the first limiting member 16 and the second limiting member 17 can drive the driving pin 21 to slide laterally along the straight slot 19 when the sliding seat 11 slides horizontally to a specified position along the fixed rail 10 .

[0043] Embodiment 2

[0044] Furthermore, as a specific implementation of the utility model, the utility model provides a jacquard machine turning mechanism.

[0045] Specifically, Figure 3 It is given that the positioning assembly also includes a support seat 5 fixedly installed on the front end face of the lower frame 1, and a movable seat 6 is rotatably installed on the support seat 5. The movable seat 6 is an L-shaped structure, and one end of the long side of the movable seat 6 is rotatably connected to the support seat 5. An adjusting bolt 7 is threadedly connected to the short side of the movable seat 6, and a clamping plate 8 is rotatably connected to the bottom end of the adjusting bolt 7. A connecting seat 3 is fixedly installed on the rear end face of the lower frame 1, and a hinge piece 4 is rotatably installed on the connecting seat 3. The hinge piece 4 is fixedly connected to the rear end face of the upper frame 2, and a flexible pad 9 is installed on the side where the lower frame 1 and the upper frame 2 are in contact with each other. The material of the flexible pad 9 is rubber, and the outer surface of the flexible pad 9 is integrally formed with anti-slip texture.

[0046] In the utility model, the upper frame 2 is conveniently rotated and overlapped on the top surface of the lower frame 1 by the provided connecting seat 3 and the hinge piece 4, so as to facilitate the pressing and fixing of the fabric. The movable seat 6 can be rotated on the lower frame 1 by the provided supporting seat 5, so as to facilitate the rotation of the movable seat 6 to the upper surface of the upper frame 2, and then the adjusting bolt 7 is rotated to make it move along the movable seat 6. The adjusting bolt 7 can push the clamping plate 8 to press the upper frame 2 on the lower frame 1, thereby improving the stability of fixing the fabric. At the same time, the flexible pad 9 provided between the lower frame 1 and the upper frame 2 can increase the friction between the lower frame 1 and the upper frame 2 and the fabric, thereby further improving the stability of fixing the fabric.

[0047] Working principle: by placing the fabric on the top surface of the lower frame 1, and then rotating the upper frame 2 to cover the lower frame 1, the fabric can be clamped and fixed by the cooperation of the lower frame 1 and the upper frame 2, and the upper frame 2 can be rotated and overlapped on the top surface of the lower frame 1 through the provided connecting seat 3 and the hinge plate 4, so as to facilitate the pressing and fixing of the fabric, and the movable seat 6 can be rotated on the lower frame 1 through the provided supporting seat 5, so as to facilitate the rotation of the movable seat 6 to the upper surface of the upper frame 2, and then the adjusting bolt 7 can be rotated to make it move along the movable seat 6, and the adjusting bolt 7 can push the pressing plate 8 to The upper frame 2 is pressed against the lower frame 1 to improve the stability of the fabric fixation. At the same time, the flexible pad 9 arranged between the lower frame 1 and the upper frame 2 can increase the friction between the lower frame 1, the upper frame 2 and the fabric, further improving the stability of the fabric fixation. Then, the jacquard machine is used to jacquard the fabric. After the jacquard on one side of the fabric is completed, the servo electric cylinder 12 drives the sliding seat 11 to slide on the fixed rail 10. During the sliding process of the sliding seat 11, the transmission gear 14 is driven to move synchronously. Since the transmission gear 14 and the tooth 15 are on the same axis at this time, when the transmission When the gear 14 moves to the position of the tooth 15, the meshing of the transmission gear 14 and the tooth 15 can drive the transmission gear 14 to drive the connecting shaft 13 to rotate, and the connecting shaft 13 drives the lower frame 1 and the upper frame 2 to flip 180 degrees as a whole. As the servo electric cylinder 12 continues to pull the sliding seat 11 to move, the second limiter 17 will push the transmission pin 21 to move laterally along the straight notch 19. The movement of the straight notch 19 drives the drive frame 20 to slide toward the outside of the through hole 18. The drive frame 20 can push the transmission gear 14 to move away from the sliding seat 11, and then use the servo electric cylinder 12 The sliding seat 11 is pushed to reset. Due to the push of the driving frame 20, the transmission gear 14 and the teeth 15 are not on the same axis, so that the transmission gear 14 avoids the teeth 15 during the reset of the sliding seat 11, so that the transmission gear 14 does not rotate. When the sliding seat 11 returns to the initial position, the transmission pin 21 slides and resets along the straight notch 19 under the transmission of the first limit member 16. The straight notch 19 drives the driving frame 20, the transmission gear 14 and the connecting shaft 13 to reset synchronously, thereby achieving the effect of turning over the fabric. The structure is simple, the operation is convenient, and the jacquard efficiency of the fabric is improved.
