Description

Technical Field

[0001] The present invention belongs to the technical field of edge peeling of weft knitting machines, and particularly relates to an edge peeling and cloth rolling device and method for a weft knitting machine. Background Art

[0002] A weft knitting machine is a knitting machine used for producing weft knitted fabrics. It is a production equipment that uses knitting needles to form coils from yarns of various raw materials and varieties and then connects them into knitted fabrics through stringing. It mainly consists of a frame, a yarn feeding mechanism, a transmission mechanism, a lubrication and dust removal (cleaning) mechanism, an electrical control mechanism, a pulling and winding mechanism, and other auxiliary devices. The knitted fabrics produced are wound into bundles by the cloth rolling mechanism of the weft knitting machine. Since more than one kind of yarn is used in the woven fabric and the elasticity of each kind of yarn is different, when the cloth is wound after knitting, the cloth edges of the cloth will naturally curl, affecting the flatness of the rolled cloth. Therefore, it is necessary to peel the cloth edges at the horizontal ends of the cloth through an edge peeling module so that the cloth rolling roller can roll the cloth smoothly.

[0003] For example, in the patent with the publication number CN118220888A, it mainly peels the cloth through the belt on the edge peeling wheel. However, when peeling the edge of a needle textile fabric that is prone to curling and has a serious curling degree, since the fabric curls severely, during the edge peeling process, due to the large elasticity of the fabric yarn, the fabric will rebound during the edge peeling process. That is, after the fabric passes through the belt edge peeling, part of the fabric rebounds, and the fabric rebound will cause the edge peeling to be difficult to control and prone to incomplete edge peeling. Summary of the Invention

[0004] The purpose of the present invention is to provide an edge peeling and cloth rolling device and method for a weft knitting machine in view of the deficiencies of the prior art to solve the technical problems in the prior art.

[0005] The purpose of the present invention can be achieved through the following technical solutions: An edge peeling and cloth rolling device for a weft knitting machine includes a base and elastic cloth. A connecting arm is installed on the base, a winding roller is installed on the connecting arm, an adjusting pressure roller and an edge peeling assembly are respectively installed on the base, the edge peeling assembly is located between the adjusting pressure rollers, and the elastic cloth passes through the gap between the adjusting pressure rollers and the edge peeling assembly and is connected to the winding roller.

[0006] The edge peeling assembly includes a sliding rod and sliding tables installed on both sides of the sliding rod. Sliding blocks are installed on both sides of the sliding tables, vertical plates are installed on the sliding blocks, a rotating cylinder and a power cylinder are respectively rotatably installed on the vertical plates, the rotating cylinder and the power cylinder are respectively connected to a driven block and a driving block through a ventilation roller and a driving roller, the driven block and the driving block are respectively slidably installed in the sliding tables, a push rod is fixedly installed on the driving block, the push rod contacts the driven block, the driven block is connected to the inner wall of the sliding table through a magnetic isolation spring, a limiting block is installed on the inner wall of the sliding table, a magnetic chuck is installed on the limiting block, the magnetic chuck adsorbs the driven block, a plurality of belts are installed on the ventilation roller and the driving roller, and a motor for driving the driving block to slide along the sliding table is installed on the sliding table.

[0007] As a further optimization or improvement of this solution, a connecting block is installed on the active block, the output end of the motor is connected to a screw rod, and the connecting block is in transmission cooperation with the screw rod.

[0008] As a further optimization or improvement of this solution, a motor is installed inside the power cylinder, the output shaft of the motor is connected to the active roller, and heat dissipation holes are installed on the power cylinder.

[0009] As a further optimization or improvement of this solution, an air vent groove is opened inside the air vent roller, air outlet holes are opened in the air vent groove, the air vent roller is rotatably connected to the rotating cylinder, a connecting rod is fixedly installed in the air vent groove, a spiral blade is installed on the connecting rod, an air inlet pipe is fixedly installed on the driven block, the air inlet pipe is inserted into the air vent groove, an air inlet hole is opened at the bottom of the air inlet pipe, the air vent roller blocks the air inlet hole, and the spiral blade is located inside the air inlet pipe.

[0010] As a further optimization or improvement of this solution, a hole groove is opened inside the active roller, a plug rod is fixedly installed on the active block, the plug rod is inserted into the hole groove, and the active roller is rotatably connected to the power cylinder.

[0011] As a further optimization or improvement of this solution, the adjusting pressure roller and the belt are in contact with the elastic fabric.

[0012] A method for edge peeling and cloth rolling of a weft knitting machine, the method is applied to the edge peeling and cloth rolling device of the weft knitting machine as described above, and the method includes the following steps:

[0013] Step S1: Pass the elastic fabric through the gap between the adjusting pressure roller and the edge peeling assembly and connect it to the winding roller;

[0014] Step S2: The motor drives the connecting block and the active block to move synchronously through the screw rod. At this time, the active block moves along the inner chute of the sliding table. At the same time, the active block pushes the driven block to move synchronously through the push rod. When the driven block touches the limit block, the magnetic suction cup on the limit block is activated and adsorbs the driven block. At this time, both the air vent roller and the active roller are in an inclined state, and the belt on them contacts the elastic fabric;

[0015] Step S3: Then adjust the position of the adjusting pressure roller so that the belt can contact the elastic fabric completely;

[0016] Step S4: Control the motor to reverse, and the motor drives the active block to reset. Since the magnetic suction cup on the limit block fixes the driven block, at this time, the air vent roller is in an inclined state, the active roller is in a vertical state, and the belts at the bottom of the air vent roller and the active roller are gradually tightened, so that the belt is gradually tightened from top to bottom;

[0017] Step S5: The power cylinder drives the active roller to rotate. When the elastic fabric passes through the belt, the edge peeling force of the belt on the elastic fabric gradually increases, and the gradually increasing edge peeling force of the belt can control the rebound amount of the elastic fabric.

[0018] As a further optimization or improvement of this solution, step S4 specifically includes the following steps:

[0019] Step S41: When the ventilation roller is adjusted to an inclined state and the driving roller is adjusted to a vertical state, the belt at the bottom of the ventilation roller and the driving roller is gradually tightened. At this time, the air inlet pipe gradually moves out of the ventilation groove, and the ventilation roller releases the blockage of the air inlet hole.

[0020] Step S42: When the motor controls the driving roller to rotate, the driving roller drives the ventilation roller to rotate through the belt. At this time, the ventilation roller rotates synchronously with the spiral blade.

[0021] Step S43: The spiral blade rotates to draw external air into the ventilation groove through the air inlet hole and discharge it from the air outlet hole.

[0022] Advantages of the present invention:

[0023] (1) In the present invention, the motor drives the driving block and the driven block to move synchronously. When the driven block contacts the limit block, the magnetic suction cup on the limit block starts to adsorb the driven block. At this time, both the ventilation roller and the driving roller are in an inclined state, and the belt on them contacts the elastic fabric. Then, adjust the position of the adjusting pressure roller so that the entire belt can contact the elastic fabric. Then, by controlling the motor to reverse, the motor drives the driving block to reset. At this time, the ventilation roller is in an inclined state and the driving roller is in a vertical state. The belt at the bottom of the ventilation roller and the driving roller is gradually tightened, so that the belt is gradually tightened from top to bottom.

[0024] When the elastic fabric with severe curling passes through the belt, the edge peeling force of the belt on the elastic fabric gradually increases. The gradually increasing edge peeling force of the belt can control the rebound amount of the elastic fabric. Combined with the compact design of the belt, it is more conducive to controlling the rebound amount of the elastic fabric and avoiding the phenomenon of incomplete edge peeling.

[0025] (2) When the ventilation roller is adjusted to an inclined state and the driving roller is adjusted to a vertical state, the belt at the bottom of the ventilation roller and the driving roller is gradually tightened. At this time, the air inlet pipe gradually moves out of the ventilation groove, and the ventilation roller releases the blockage of the air inlet hole. When the motor controls the driving roller to rotate, the driving roller drives the ventilation roller to rotate through the belt. At this time, the ventilation roller rotates synchronously with the spiral blade. The spiral blade rotates to draw external air into the ventilation groove through the air inlet hole and discharge it from the air outlet hole, realizing the heat dissipation of the belt, so as to avoid the influence of the heat generated by the work of the belt on the quality of the elastic fabric.

[0041] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0042] Refer to Figures 1 - 13 , a selvage stripping and cloth winding device for a weft knitting machine, which includes a base 1 and an elastic cloth 5. A connecting arm 2 is installed on the base 1, a winding roller 3 is installed on the connecting arm 2, an adjusting pressure roller 4 and a selvage stripping assembly 6 are respectively installed on the base 1, the selvage stripping assembly 6 is located between the adjusting pressure rollers 4, and the elastic cloth 5 passes through the gap between the adjusting pressure rollers 4 and the selvage stripping assembly 6 and is connected to the winding roller 3;

[0043] The selvage stripping assembly 6 includes a slide bar 601 and sliding platforms 602 installed on both sides of the slide bar 601. Slide blocks 608 are installed on both sides of the sliding platform 602, a vertical plate 604 is installed on the slide block 608, a rotating cylinder 605 and a power cylinder 606 are respectively rotatably installed on the vertical plate 604, the rotating cylinder 605 and the power cylinder 606 are respectively connected to a driven block 611 and a driving block 613 through a ventilation roller 615 and a driving roller 614, the driven block 611 and the driving block 613 are respectively slidably installed in the slide block 608, a push rod 612 is fixedly installed on the driving block 613, the push rod 612 contacts the driven block 611, the driven block 611 is connected to the inner wall of the slide block 608 through a magnetic isolation spring 610, a limit block 609 is installed on the inner wall of the slide block 608, a magnetic chuck 619 is installed on the limit block 609, the magnetic chuck 619 adsorbs the driven block 611, a plurality of belts 603 are installed on the ventilation roller 615 and the driving roller 614, and a motor 616 for driving the driving block 613 to slide along the slide block 608 is installed on the slide block 608.

[0044] Specifically, a motor 620 is installed in the power cylinder 606, the output shaft of the motor 620 is connected to the driving roller 614, and heat dissipation holes 607 are installed on the power cylinder 606.

[0045] Specifically, the adjusting pressure roller 4 and the belt 603 are in contact with the elastic cloth 5.

[0046] It should be noted that the yarn passes through the cloth production assembly to produce the elastic cloth 5, and then the elastic cloth 5 passes through the gap between the adjusting pressure roller 4 and the selvage stripping assembly 6 and is connected to the winding roller 3. During the production of the elastic cloth 5, the winding roller 3 can automatically rotate to realize the cloth winding function.

[0047] When the selvage stripping assembly 6 is in use, refer to Figure 7 、 Figure 9 and Figure 11, start the motor 616. The motor 616 drives the connecting block 618 and the active block 613 to move synchronously through the screw 617. At this time, the active block 613 moves along the inner chute of the sliding table 608. At the same time, the active block 613 pushes the driven block 611 to move synchronously through the push rod 612. During the movement of the driven block 611, the magnetic isolation spring 610 is gradually compressed. When the driven block 611 touches the limit block 609, the magnetic chuck 619 on the limit block 609 is activated and adsorbs the driven block 611. At this time, the ventilation roller 615 and the driving roller 614 are both in an inclined state, and the belt 603 on them contacts the elastic fabric 5. Then, adjust the position of the adjusting pressure roller 4 so that the belt 603 can contact the elastic fabric 5 completely.

[0048] Control the motor 616 to reverse. The motor 616 drives the active block 613 to reset. Since the magnetic chuck 619 on the limit block 609 fixes the driven block 611, at this time, the ventilation roller 615 is in an inclined state, and the driving roller 614 is in a vertical state. The belt 603 at the bottom of the ventilation roller 615 and the driving roller 614 is gradually tightened, so that the belt 603 is gradually tightened from top to bottom.

[0049] See Figure 6 , start the motor 620 inside the power cylinder 606. The motor 620 drives the driving roller 614 to rotate. If the elastic fabric 5 with severe curling passes between the adjusting pressure roller 4 and the belt 603, the edge peeling force of the belt 603 on the elastic fabric 5 gradually increases. When the elastic fabric 5 passes through the belt 603, the gradually increasing edge peeling force of the belt 603 can control the springback amount of the elastic fabric 5, reduce the springback amount of the elastic fabric 5, and cooperate with the compact design of the belt 603, which is more conducive to controlling the springback amount of the elastic fabric 5 and avoiding the phenomenon of incomplete edge peeling.

[0050] Specifically, in order to more clearly express that the gradually increasing edge peeling force of the belt 603 can reduce the springback amount of the elastic fabric 5, the hypothesis method is used to set that there are five curls on the elastic fabric 5. When the elastic fabric 5 passes through the first group of belts 603, the first group of belts 603 can flatten one curl on the elastic fabric 5 (the springback amount of the elastic fabric 5 is the springback based on the flattening of one curl), and there are four remaining curls on the elastic fabric 5; when the elastic fabric 5 passes through the second group of belts 603, due to the increased edge peeling force of the second group of belts 603, the second group of belts 603 can flatten two of the remaining four curls on the elastic fabric 5 (the springback amount of the elastic fabric 5 is the springback based on the flattening of two curls), and so on. The springback amount of the elastic fabric 5 is controlled.

[0051] It should be noted that when the fabric yarn has high elasticity, the distance between the winding roller 3 and the edge stripping assembly 6 can be appropriately shortened, which is beneficial to the winding of the fabric by the winding roller 3 and can, to a certain extent, prevent the fabric from rebounding during the winding process of the elastic fabric 5. In actual use, the number of the belts 603 is usually set to two or three groups. The number of the belts 603 shown in the attached drawings of the present invention is for expressing the states of the ventilation roller 615 and the driving roller 614, rather than the actual quantity standard.

[0052] See Figures 8 - 9 , a connecting block 618 is installed on the active block 613, the output end of the motor 616 is connected to a screw 617, and the connecting block 618 is in transmission cooperation with the screw 617.

[0053] It should be noted that the elastic fabric 5 entering the adjusting pressure roller 4 and the edge stripping assembly 6 is two pieces of fabric. Therefore, components such as the driving roller 614, the ventilation roller 615, and the belts 603 thereon are provided in two groups. When the motor 616 controls the screw 617 to rotate, the screw 617 can drive the two groups of active blocks 613 to move simultaneously through the connecting block 618, improving the working efficiency of the edge stripping assembly 6. Since the screw 617 is a bidirectional threaded rod, the motor 616 drives the two groups of active blocks 613 to move relatively.

[0054] See Figures 10 - 12 , a ventilation groove 6151 is formed in the ventilation roller 615, an air outlet hole 6150 is formed in the ventilation groove 6151, the ventilation roller 615 is rotatably connected to a rotating cylinder 605, a connecting rod 6152 is fixedly installed in the ventilation groove 6151, a spiral blade 6153 is installed on the connecting rod 6152, an air inlet pipe 6154 is fixedly installed on the driven block 611, the air inlet pipe 6154 is inserted into the ventilation groove 6151, an air inlet hole 6155 is formed at the bottom of the air inlet pipe 6154, the ventilation roller 615 blocks the air inlet hole 6155, and the spiral blade 6153 is located in the air inlet pipe 6154.

[0055] Specifically, a hole groove 6140 is formed in the driving roller 614, a plug rod 6141 is fixedly installed on the active block 613, the plug rod 6141 is inserted into the hole groove 6140, and the driving roller 614 is rotatably connected to a power cylinder 606.

[0056] It should be noted that when the belts 603 at the bottoms of the driving roller 614 and the ventilation roller 615 are tightened, the friction between the belts 603 and the driving roller 614 and the ventilation roller 615 increases, and the heat generated during the operation of the belts 603 also increases. The increase in the heat generated by the operation of the belts 603 is likely to affect the quality of the elastic fabric 5.

[0057] When the present invention is in use, when the ventilation roller 615 is adjusted to an inclined state and the driving roller 614 is adjusted to a vertical state, the belts 603 at the bottoms of the ventilation roller 615 and the driving roller 614 are gradually tightened. See Figure 13, at this time, the intake pipe 6154 gradually moves out of the ventilation slot 6151. At this time, the ventilation roller 615 releases the blockage of the intake hole 6155. When the motor 620 controls the rotation of the driving roller 614, the driving roller 614 drives the ventilation roller 615 to rotate through the belt 603. At this time, the ventilation roller 615 rotates synchronously with the spiral blade 6153. The rotation of the spiral blade 6153 sucks external air into the ventilation slot 6151 through the intake hole 6155 and discharges it from the air outlet hole 6150, realizing the heat dissipation of the belt 603, so as to avoid the influence of the heat generated by the work of the belt 603 on the quality of the elastic fabric 5.

[0058] It should be noted that the spiral blade 6153 can be replaced with a fan blade to improve the ventilation efficiency of the air outlet hole 6150.

[0059] Please refer to Figures 3 - 12 As shown, the present invention is a method for peeling and winding the edge of a weft knitting machine. The method is applied to the peeling and winding device of the weft knitting machine as described in the above embodiment. The method includes the following steps:

[0060] Step S1: Pass the elastic fabric 5 through the gap between the adjusting pressure roller 4 and the edge peeling assembly 6 and connect it to the winding roller 3;

[0061] Step S2: The motor 616 drives the connecting block 618 and the driving block 613 to move synchronously through the screw 617. At this time, the driving block 613 moves along the inner chute of the sliding table 608. At the same time, the driving block 613 pushes the driven block 611 to move synchronously through the push rod 612. When the driven block 611 contacts the limit block 609, the magnetic chuck 619 on the limit block 609 is activated and adsorbs the driven block 611. At this time, both the ventilation roller 615 and the driving roller 614 are in an inclined state, and the belt 603 thereon contacts the elastic fabric 5;

[0062] Step S3: Then adjust the position of the adjusting pressure roller 4 so that the entire belt 603 can contact the elastic fabric 5;

[0063] Step S4: Control the motor 616 to reverse. The motor 616 drives the driving block 613 to reset. Since the magnetic chuck 619 on the limit block 609 fixes the driven block 611, at this time, the ventilation roller 615 is in an inclined state and the driving roller 614 is in a vertical state. The belt 603 at the bottom of the ventilation roller 615 and the driving roller 614 is gradually tightened, so that the belt 603 is gradually tightened from top to bottom;

[0064] Step S5: The power cylinder 606 drives the driving roller 614 to rotate. When the elastic fabric 5 passes through the belt 603, the edge peeling force of the belt 603 on the elastic fabric 5 gradually increases, and the gradually increasing edge peeling force of the belt 603 can control the rebound amount of the elastic fabric 5.

[0065] As Figures 6 - 13As shown, as a preferred embodiment of the present invention, step S4 specifically includes the following steps:

[0066] Step S41: When the ventilation roller 615 is adjusted to an inclined state and the driving roller 614 is adjusted to a vertical state, the belt 603 at the bottom of the ventilation roller 615 and the driving roller 614 is gradually tightened. At this time, the air inlet pipe 6154 gradually moves out of the ventilation groove 6151, and at this time, the ventilation roller 615 releases the blockage of the air inlet hole 6155.

[0067] Step S42: When the motor 620 controls the driving roller 614 to rotate, the driving roller 614 drives the ventilation roller 615 to rotate through the belt 603. At this time, the ventilation roller 615 rotates synchronously with the spiral blade 6153.

[0068] Step S43: The spiral blade 6153 rotates to draw external air into the ventilation groove 6151 through the air inlet hole 6155 and discharge it from the air outlet hole 6150.

[0069] The implementation principle of the present invention is as follows:

[0070] During use, refer to Figure 7 、 Figure 9 and Figure 11 , start the motor 616. The motor 616 drives the connecting block 618 and the driving block 613 to move synchronously through the screw 617. At this time, the driving block 613 moves along the inner chute of the sliding table 608. At the same time, the driving block 613 pushes the driven block 611 to move synchronously through the push rod 612. During the movement of the driven block 611, the magnetic isolation spring 610 is gradually compressed. When the driven block 611 contacts the limit block 609, the magnetic chuck 619 on the limit block 609 is activated and adsorbs the driven block 611. At this time, both the ventilation roller 615 and the driving roller 614 are in an inclined state, and the belt 603 thereon contacts the elastic fabric 5. Then, adjust the position of the adjusting pressure roller 4 so that the belt 603 can all contact the elastic fabric 5.

[0071] Reverse the control motor 616. The motor 616 drives the active block 613 to reset. Since the magnetic chuck 619 on the limit block 609 fixes the driven block 611, at this time, the ventilation roller 615 is in an inclined state, and the driving roller 614 is in a vertical state. The belt 603 at the bottom of the ventilation roller 615 and the driving roller 614 is gradually tightened, so that the belt 603 is gradually tightened from top to bottom. At this time, the air inlet pipe 6154 gradually moves out of the ventilation groove 6151. At this time, the ventilation roller 615 releases the blockage of the air inlet hole 6155. When the motor 620 controls the driving roller 614 to rotate, the driving roller 614 drives the ventilation roller 615 to rotate through the belt 603. At this time, the ventilation roller 615 rotates synchronously with the spiral blade 6153. The spiral blade 6153 rotates to draw external air into the ventilation groove 6151 through the air inlet hole 6155 and discharge it from the air outlet hole 6150, realizing the heat dissipation of the belt 603, so as to avoid the influence of the heat generated by the work of the belt 603 on the quality of the elastic fabric 5.

[0072] When the elastic fabric 5 with severe curling passes between the adjusting roller 4 and the belt 603, the edge peeling force of the belt 603 on the elastic fabric 5 gradually increases. When the elastic fabric 5 passes through the belt 603, the gradually increasing edge peeling force of the belt 603 can control the rebound amount of the elastic fabric 5. With the compact design of the belt 603, it is more conducive to controlling the rebound amount of the elastic fabric 5 and avoiding the phenomenon of incomplete edge peeling.

[0073] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
