[0003] In the Chinese utility model patent with the publication number CN221369734U, a double-sided circular weft knitting machine with high efficiency is disclosed, which comprises a body and a winding assembly. The winding assembly is installed inside the body. The winding assembly comprises a motor. The end of the motor output is fixedly connected with a connecting shaft.

The end of the rotating shaft away from the connecting shaft is threadedly connected with a fixed shaft. The outer wall of the winding roller is fixedly connected with a limiting disc.

[0004] According to the related technology in the above, the inventors believe that there are the following defects: During the process of connecting the fabric to be wound with the winding roller to be wound, the staff needs to manually wrap the fabric around the outer wall of the winding roller and hold it on the surface of the fabric with their hands. Then, the motor is started to make the winding roller rotate and pre-wind the fabric. However, the rotating winding roller and the wound fabric may injure the staff, and the safety is low. UTILITY MODEL CONTENTS

[0005] In order to solve the above problems, the utility model provides a light warm clothing face fabric preparation device.

[0006] The above technical purpose of the utility model is realized by the following technical scheme: a light warm clothing face fabric preparation device, which comprises a weft knitting machine, a mounting seat fixed in the weft knitting machine, and a vertical plate fixed on the top of the mounting seat. A winding roller and a rotating mechanism for driving the winding roller to rotate are arranged on the vertical plate. Two limiting discs are arranged on the winding roller in pairs and are symmetric about the midpoint of the winding roller axis. An arc limiting groove extending to both ends of the winding roller is formed on the winding roller, and the length direction of the arc limiting groove is parallel to the axial direction of the winding roller. A pressing strip is arranged on each limiting disc. The side of the pressing strip close to the winding roller axis is an arc surface matched with the arc limiting groove. An extrusion mechanism is arranged on the limiting disc to extrude the pressing strip, so that the arc surface of the pressing strip is matched with the arc limiting groove and the fabric is clamped.

[0007] By adopting the above technical scheme, when winding the one end of the fabric to be wound on the winding roller, the worker needs to adjust the extrusion mechanism to drive the pressing strip to move away from the direction of the circular arc limiting groove, until the pressing strip is separated from the circular arc limiting groove, then the fabric to be wound is passed through the pressing strip and the side wall of the winding roller, then the extrusion mechanism is adjusted to drive the pressing strip to move towards the direction of approaching the circular arc limiting groove, until the circular arc surface of the pressing strip and the circular arc surface of the circular arc limiting groove cooperate and abut against the fabric, and finally the winding roller is driven to rotate by the rotating mechanism to wind the fabric, which eliminates the need to hold the surface of the fabric after winding the fabric on the side wall of the winding roller, and improves the safety.

[0008] Further, the limiting disc is provided with a cavity, the outer side wall of the limiting disc is provided with a first circular through hole communicated with the cavity, and the inner side wall of the limiting disc is provided with an installation through hole communicated with the cavity and allowing the pressing strip to pass through at a position corresponding to the first circular through hole. The extrusion mechanism comprises a cylindrical rod in clearance fit with the first circular through hole and connected with the side of the pressing strip away from the axis of the winding roller, a fixed block fixed on the inner side wall of the cavity, a clamping spring fixed between the pressing strip and the fixed block and sleeved on the cylindrical rod, and an operation handle fixed on the end of the cylindrical rod away from the winding roller and located outside the limiting disc. The cylindrical rod penetrates through the fixed block and is in clearance fit with the fixed block. The circular arc surface of the pressing strip is abutted against the circular arc surface of the circular arc limiting groove under the action of the clamping spring.

[0009] By adopting the above technical scheme, after the worker pulls the operation handle away from the axis of the winding roller, the cylindrical rod penetrates through the fixed block and is in clearance fit with the fixed block, so that the cylindrical rod fixed with the operation handle and the pressing strip fixed with the cylindrical rod are both moved. In this process, the clamping spring is gradually compressed under stress between the pressing strip and the fixed block, until the pressing strip is away from the circular arc limiting groove. At this time, the fabric can be easily passed through the pressing strip and the side wall of the winding roller, and then the operation handle is released, the clamping spring is reset, so that the pressing strip, the operation handle and the cylindrical rod are all reset. Since the circular arc surface of the pressing strip cooperates with the circular arc surface of the circular arc limiting groove under the action of the clamping spring and clamps the fabric, subsequent winding work is facilitated.

[0010] Further, the end of the cylindrical rod close to the axis of the winding roller is rotationally connected with the side wall of the side of the pressing strip away from the axis of the winding roller. The side wall of the cylindrical rod is fixed with a limiting block located between the fixed block and the outer wall of the cavity. The outer side wall of the limiting disc is provided with a connecting through hole communicated with the first circular through hole and allowing the limiting block to pass through.

[0011] By adopting the technical scheme, when the staff controls the operation handle and moves the cylindrical rod away from the winding roller, the limiting block fixed with the cylindrical rod moves to the outside of the limiting disc through the connecting through hole. Since the cylindrical rod is rotationally connected with the pressing strip, and the side walls on both sides of the pressing strip abut against the inner walls on both sides of the mounting through hole, at this time, the cylindrical rod is rotated, so that the limiting block is rotated and abuts against the outer sidewall of the limiting disc, thereby limiting the cylindrical rod, so that the distance between the pressing strip and the winding roller is kept fixed, so that the staff can pass the cloth between the pressing strip and the winding roller.

[0012] Further, the limiting disc is provided with a distance adjusting mechanism for adjusting the distance between the two limiting discs. A second circular through hole in communication with the cavity is provided through the outer sidewall of the limiting disc. The sliding through hole is in communication with the second circular through hole.

One end of the positioning rod away from the axis of the winding roller is connected with one end of the cylindrical sliding rod close to the axis of the winding roller. The positioning rod penetrates the inner sidewall of the limiting disc and is in clearance fit. The outer wall of the winding roller is provided with positioning holes arranged in a straight line. When the positioning spring is in compression, the positioning rod is in plug-in fit with the corresponding positioning hole. The distance between the end face of the one end of the positioning rod close to the axis of the winding roller and the axis of the winding roller is greater than the distance between the sidewall of the one side of the positioning hole close to the axis of the winding roller and the axis of the winding roller. The limiting baffle abuts against the inner wall of the side of the cavity away from the axis of the winding roller. A sliding through hole in communication with the cavity and the second circular through hole and for the limiting baffle to pass through is provided through the outer sidewall of the limiting disc. The sliding through hole is in communication with the second circular through hole.

[0013] By adopting the technical scheme, the staff rotates the auxiliary block to drive the cylindrical slide rod to rotate, so that the limiting baffle fixed with the cylindrical slide rod rotates until the limiting baffle moves to the position of the sliding through hole, at this time, the staff needs to loosen the auxiliary block, and the cylindrical slide rod and the limiting baffle move to the side away from the axis of the winding roller under the action of the positioning spring until the limiting baffle completely passes through the sliding through hole, and the end of the positioning rod close to the axis of the winding roller is separated from the positioning hole, then the auxiliary block is pushed towards the direction of the axis of the winding roller and reset after moving the limiting disc to the required position along the axis of the winding roller, so that the cylindrical slide rod, the limiting baffle and the positioning rod are reset, at this time, the positioning spring is in a compressed state, the positioning rod is inserted into the corresponding positioning hole, and finally the auxiliary block is rotated to drive the limiting baffle to rotate until the limiting baffle abuts against the inner wall of the cavity away from the axis of the winding roller, and the positioning rod is inserted into the positioning hole to limit the limiting disc. Similarly, the above operation is repeated to adjust the position of the other limiting disc. The distance between the two limiting discs can be adjusted according to the width of the cloth, and the application range of the winding roller is improved.

[0014] Further, the end of the cylindrical slide rod close to the axis of the winding roller is rotatably installed with a rotating plate, and the positioning spring is fixed between the rotating plate and the fixed plate.

[0015] By adopting the technical scheme, the rotating plate is arranged, and the positioning spring does not rotate with the cylindrical slide rod during the rotation of the cylindrical slide rod, so that the smoothness during the rotation of the cylindrical slide rod is improved.

[0016] Further, the inner wall of the cavity away from the axis of the winding roller is fixed with a U-shaped block inserted into the limiting baffle.

[0017] By adopting the technical scheme, the staff moves the auxiliary block towards the direction of the axis of the winding roller until the positioning rod abuts against the side wall of the positioning hole close to the axis of the winding roller, at this time, the distance between the side wall of the limiting baffle away from the axis of the winding roller and the axis of the winding roller is smaller than the distance between the side wall of the U-shaped block close to the axis of the winding roller and the axis of the winding roller, and the positioning spring is compressed to the minimum length, then the auxiliary block is rotated to drive the limiting baffle to rotate until the limiting baffle moves to the position between the block bodies on both sides of the U-shaped block, after the auxiliary block is loosened, the positioning spring is elongated to drive the limiting baffle to move away from the axis of the winding roller until the limiting baffle is inserted into the block bodies on both sides of the U-shaped block, and the U-shaped block plays a good limiting role on the limiting baffle to ensure the stability when the positioning rod is inserted into the positioning hole.

[0018] Further, the rotating mechanism comprises a rotating assembly, the rotating assembly comprises a moving plate arranged on the top of the mounting base, a first transmission column rotatably arranged on the side wall of the vertical plate close to the moving plate, a second transmission column rotatably arranged on the side wall of the moving plate close to the vertical plate, and a rotating motor fixed on the vertical plate and used for driving the first transmission column to rotate, two ends of the winding roller are connected with the ends of the first transmission column and the second transmission column close to each other, and the rotating mechanism further comprises a moving assembly used for driving the moving plate to move.

[0019] By adopting the above technical scheme, the rotating motor drives the first transmission column to rotate after working, so that the winding roller connected with the first transmission column and the second transmission column connected with the winding roller are all rotated, so as to wind the cloth.

[0020] Further, the top of the mounting base is provided with a transverse sliding groove, the ends of the first transmission column and the second transmission column close to each other are both provided with a rectangular mounting groove, the two ends of the winding roller are both fixed with a rectangular connecting block, the two rectangular connecting blocks are both inserted and matched with the corresponding rectangular mounting grooves, the moving assembly comprises a threaded rod rotatably arranged between the inner walls of the two sides of the transverse sliding groove, a sliding seat threadedly connected with the threaded rod and slidably matched with the transverse sliding groove, and a moving motor fixed on the mounting base and driving the threaded rod to rotate, the top of the sliding seat is fixed with the bottom of the moving plate, and the output shaft of the moving motor is in transmission with the threaded rod through a synchronous wheel and a synchronous belt.

[0021] By adopting the above technical scheme, the moving motor drives the threaded rod to rotate through the synchronous wheel and the synchronous belt after working, since the sliding seat is threadedly connected with the threaded rod and slidably matched with the transverse sliding groove, the sliding seat, the moving plate fixed with the sliding seat and the second transmission column connected with the moving plate move towards the direction away from or close to the vertical plate, until the rectangular mounting groove of the second transmission column is separated from or inserted with the corresponding rectangular connecting block, so as to realize the purpose of disassembling or assembling the winding roller.

[0022] Further, the side walls close to each other of the two pressing strips are both provided with a connecting groove, a connecting rod slidably matched with the two connecting grooves is arranged between the two pressing strips, and the length of the axis of the connecting rod is greater than the distance between the two pressing strips.

[0025] In summary, the utility model has the following beneficial effects: in the application, through setting up the pressing strip, the circular arc limit slot and the extrusion mechanism, the cloth to be rolled up can pass between the pressing strip and the circular arc limit slot, and the extrusion mechanism makes the arc surface of the pressing strip cooperate with the circular arc limit slot and clamp the fabric, so that the operation of holding the fabric surface by hand after winding the cloth around the side wall of the rolling roller is avoided, and the safety is improved.

DETAILED DESCRIPTION

[0034] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application, and all other embodiments obtained by a person of ordinary skill in the art without creative effort based on the embodiments of the present application shall fall within the protection scope of the present application.

[0035] As shown in Figures 1-7 The present application discloses a lightweight warm clothing fabric preparation device, which comprises a weft knitting machine 1, a mounting seat 2, a vertical plate 3, a winding roller 4, a rotating mechanism 5, an extrusion mechanism 9 and a distance adjusting mechanism 14. The mounting seat 2 is fixed in the weft knitting machine 1, and a horizontal sliding groove 20 is arranged on the top of the mounting seat 2. The vertical plate 3 is fixed on the top of the mounting seat 2 and is integrally formed. The winding roller 4 is arranged on the vertical plate 3. Rectangular connecting blocks 22 are fixed to both ends of the winding roller 4. A plurality of positioning holes 16 arranged in a straight line are formed on the outer wall of the winding roller 4. An arc limiting groove 7 extending to both ends of the winding roller 4 is formed on the winding roller 4, and the length direction of the arc limiting groove 7 is parallel to the axial direction of the winding roller 4. A pair of limiting discs 6 are arranged on the winding roller 4, and the two limiting discs 6 are symmetric about the midpoint of the axis of the winding roller 4. A pressing strip 8 is arranged on each limiting disc 6, and the side of the pressing strip 8 close to the axis of the winding roller 4 is an arc surface matched with the arc limiting groove 7. A connecting hole is formed at the end of each pressing strip 8 close to the other pressing strip 8. A connecting rod 23 is arranged between the two pressing strips 8 and is inserted into the two connecting holes. A cavity is arranged in the limiting disc 6. A first circular through hole 10 is formed through the outer side wall of the limiting disc 6 and communicates with the cavity. An installation through hole 11 is formed in the inner side wall of the limiting disc 6 and communicates with the cavity and is used for allowing the pressing strip 8 to pass through.

[0036] The rotating mechanism 5 comprises a rotating assembly 51 and a moving assembly 52. The rotating mechanism 5 is arranged on the vertical plate 3 and is used for driving the winding roller 4 to rotate. The rotating mechanism 5 comprises a rotating assembly 51 and a moving assembly 52. The rotating assembly 51 comprises a moving plate 511, a first transmission column 512, a second transmission column 513 and a rotating motor 514. The moving plate 511 is arranged on the top of the mounting seat 2. The first transmission column 512 is rotatably arranged on the side wall of the vertical plate 3 close to the moving plate 511. The second transmission column 513 is rotatably arranged on the side wall of the moving plate 511 close to the vertical plate 3. The rotating motor 514 is fixed on the vertical plate 3 and is used for driving the first transmission column 512 to rotate. The first transmission column 512 and the second transmission column 513 are provided with rectangular installation grooves 21 at the ends close to each other. The two rectangular connecting blocks 22 are inserted into the corresponding rectangular installation grooves 21.

[0037] The pressing mechanism 9 is arranged on the limiting disc 6 and is used for pressing the pressing strip 8, so that the arc surface of the pressing strip 8 is matched with the arc limiting groove 7 and the fabric is clamped. The pressing mechanism 9 comprises a cylindrical rod 91, a fixed block 92, a clamping spring 93 and an operation handle 94, the cylindrical rod 91 is matched with the first circular through hole 10 in clearance and is connected with the side of the pressing strip 8 away from the axis of the winding roller 4. The fixed block 92 is fixed on the inner side wall of the cavity, and the cylindrical rod 91 penetrates through the fixed block 92 and is matched with the fixed block 92 in clearance. The side wall of the cylindrical rod 91 is fixed with a limiting stop 12 between the fixed block 92 and the outer wall of the cavity, and the outer side wall of the limiting disc 6 is provided with a connecting through hole 13 which is communicated with the first circular through hole 10 and is used for the limiting stop 12 to pass through. The clamping spring 93 is fixed between the pressing strip 8 and the fixed block 92 and is sleeved on the cylindrical rod 91, and the arc surface of the pressing strip 8 is abutted with the arc surface of the arc limiting groove 7 under the action of the clamping spring 93. The operation handle 94 is fixed on the end of the cylindrical rod 91 away from the winding roller 4, and the operation handle 94 is located on the outer side of the limiting disc 6.

[0038] When winding the fabric to be wound on the winding roller 4, the operation handle 94 is pulled away from the axis of the winding roller 4, so that the cylindrical rod 91 fixed with the operation handle 94 and the pressing strip 8 fixed with the cylindrical rod 91 are moved. In this process, since the clamping spring 93 is fixed between the pressing strip 8 and the fixed block 92, the clamping spring 93 is gradually compressed under force until the pressing strip 8 is away from the arc limiting groove 7, and the limiting stop 12 is located on the outer side of the limiting disc 6. At this time, rotating the operation handle 94 drives the cylindrical rod 91 to rotate, so that the limiting stop 12 rotates and abuts with the outer side wall of the limiting disc 6, thereby limiting the cylindrical rod 91, so that the distance between the pressing strip 8 and the winding roller 4 remains fixed, so as to pass the fabric to be wound between the pressing strip 8 and the side wall of the winding roller 4. Then, the limiting stop 12 is rotated to the position of the connecting through hole 13 by rotating the operation handle 94, and the operation handle 94 is released, so that the clamping spring 93 is reset, so that the pressing strip 8, the operation handle 94 and the cylindrical rod 91 are reset. Since the arc surface of the pressing strip 8 is matched with the arc surface of the arc limiting groove 7 under the action of the clamping spring 93 and clamps the fabric, the first transmission column 512 is rotated after the rotating motor 514 works, and the winding roller 4 and the second transmission column 513 are rotated under the limiting action of the rectangular mounting groove 21 and the rectangular connecting block 22, so as to wind the fabric. The operation of holding the surface of the fabric by hand after winding the fabric on the side wall of the winding roller 4 is avoided, and the safety is improved.

[0039] A second circular through hole 15 is arranged through the outer side wall of the limiting disc 6 and communicates with the cavity. A distance adjusting mechanism 14 is arranged on the limiting disc 6 and is used for adjusting the distance between the two limiting discs 6. The distance adjusting mechanism 14 comprises a cylindrical slide rod 141, a fixing plate 142, a positioning rod 143, a positioning spring 144, an auxiliary block 145 and a limiting baffle 146, and the cylindrical slide rod 141 is in clearance fit with the second circular through hole 15. The fixing plate 142 is fixed in the cavity, the positioning rod 143 is arranged on the fixing plate 142 and is in sliding fit, and the end of the positioning rod 143 away from the axis of the winding roller 4 is connected with the end of the cylindrical slide rod 141 close to the axis of the winding roller 4. The positioning rod 143 penetrates the inner side wall of the limiting disc 6 and is in clearance fit. The positioning spring 144 is sleeved on the positioning rod 143 and is located between the fixing plate 142 and the cylindrical slide rod 141. When the positioning spring 144 is in compression, the positioning rod 143 is in plug fit with the corresponding positioning hole 16, and the distance between the end face of the end of the positioning rod 143 close to the axis of the winding roller 4 and the axis of the winding roller 4 is greater than the distance between the side wall of the positioning hole 16 close to the axis of the winding roller 4 and the axis of the winding roller 4. The auxiliary block 145 is fixed on the end of the cylindrical slide rod 141 away from the winding roller 4, and the limiting baffle 146 is fixed on the side wall of the cylindrical slide rod 141 and is located in the cavity, and the limiting baffle 146 abuts against the inner wall of the side of the cavity away from the axis of the winding roller 4. A sliding through hole 17 is arranged through the outer side wall of the limiting disc 6 and communicates with the cavity and the second circular through hole 15 and is used for the limiting baffle 146 to pass through, and the sliding through hole 17 communicates with the second circular through hole 15.

[0040] The staff rotates the auxiliary block 145 to drive the cylindrical slide rod 141 to rotate, so that the limiting baffle 146 fixed with the cylindrical slide rod 141 is rotated, until the limiting baffle 146 moves to the position of the sliding through hole 17. At this time, the staff needs to loosen the auxiliary block 145, and the cylindrical slide rod 141 and the limiting baffle 146 move away from the axis of the winding roller 4 under the action of the positioning spring 144, until the limiting baffle 146 completely passes through the sliding through hole 17, and the end of the positioning rod 143 close to the axis of the winding roller 4 is separated from the positioning hole 16. Then, the limiting disc 6 is moved to the required position along the axis of the winding roller 4, and the auxiliary block 145 is pushed towards the axis of the winding roller 4 and is reset, so that the cylindrical slide rod 141, the limiting baffle 146 and the positioning rod 143 are reset. At this time, the positioning spring 144 is in compression, the positioning rod 143 is inserted into the corresponding positioning hole 16, and finally the auxiliary block 145 is rotated to drive the limiting baffle 146 to rotate, until the limiting baffle 146 abuts against the inner wall of the side of the cavity away from the axis of the winding roller 4, and the positioning rod 143 is in plug fit with the positioning hole 16 and limits the limiting disc 6. Similarly, the above operation can be repeated to adjust the position of the other limiting disc 6. The device can adjust the distance between the two limiting discs 6 according to the width of the cloth, and improve the application range of the winding roller 4.

[0041] The rotating plate 18 is rotatably installed at one end of the cylindrical slide rod 141 close to the axis of the winding roller 4, and the positioning spring 144 is fixed between the rotating plate 18 and the fixed plate 142. The rotating plate 18 is arranged so that the positioning spring 144 does not rotate with the cylindrical slide rod 141 during rotation of the cylindrical slide rod 141, thereby improving the smoothness during rotation of the cylindrical slide rod 141.

[0042] The inner wall of the cavity away from the axis of the winding roller 4 is fixed with a U-shaped block 19 which is inserted and matched with the limiting baffle 146. The staff moves the auxiliary block 145 towards the axis of the winding roller 4 until the positioning rod 143 abuts against the side wall of the positioning hole 16 close to the axis of the winding roller 4. At this time, the distance between the side wall of the limiting baffle 146 away from the axis of the winding roller 4 and the axis of the winding roller 4 is smaller than the distance between the side wall of the U-shaped block 19 close to the axis of the winding roller 4 and the axis of the winding roller 4. The positioning spring 144 is compressed to the minimum length. Then the auxiliary block 145 is rotated to drive the limiting baffle 146 to rotate until the limiting baffle 146 moves to the position between the block bodies on both sides of the U-shaped block 19. After the auxiliary block 145 is released, the positioning spring 144 is elongated and drives the limiting baffle 146 to move away from the axis of the winding roller 4 until the limiting baffle 146 is inserted and matched with the block bodies on both sides of the U-shaped block 19. The U-shaped block 19 plays a good limiting role on the limiting baffle 146, thereby ensuring the stability when the positioning rod 143 is inserted with the positioning hole 16.

[0043] The moving assembly 52 is used for driving the moving plate 511 to move, and the moving assembly 52 comprises a threaded rod 521, a sliding seat 522 and a moving motor 523. The threaded rod 521 is rotatably installed between the inner walls on both sides of the transverse sliding groove 20. The sliding seat 522 is threadedly connected with the threaded rod 521 and is in sliding fit with the transverse sliding groove 20. The moving motor 523 is fixed on the mounting seat 2 and drives the threaded rod 521 to rotate. The output end of the moving motor 523 is fixedly sleeved with a synchronous wheel on the threaded rod 521. The two synchronous wheels are in meshing connection with a synchronous belt.

[0044] When the moving motor 523 works, the threaded rod 521 is driven to rotate through the synchronous wheel and the synchronous belt. Since the sliding seat 522 is threadedly connected with the threaded rod 521 and is in sliding fit with the transverse sliding groove 20, the sliding seat 522, the moving plate 511 fixed with the sliding seat 522 and the second transmission column 513 connected with the moving plate 511 move towards the direction away from or close to the vertical plate 3 until the rectangular mounting groove 21 of the second transmission column 513 is separated from or inserted with the rectangular connecting block 22 corresponding thereto, thereby achieving the purpose of disassembling or assembling the winding roller 4.

[0045] An arc surface is arranged at the intersection of the inner wall of the arc limiting groove 7 and the outer wall of the winding roller 4. The arrangement of the arc surface reduces the probability of the fabric being scratched and causing the fabric to be raised in the process of winding by the winding roller 4.

[0046] The preferred embodiments of the present application have been described above, but the protection scope of the present application is not limited to the above-mentioned embodiments. Any technical solution falling within the concept of the present application shall fall within the protection scope of the present application. It should be noted that, for ordinary skilled persons in the technical field, some improvements and refinements without departing from the principles of the present application shall also be considered as falling within the protection scope of the present application.
