Description

Technical Field

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

[0002] A weft knitting machine is a knitting machine used to produce weft knitted fabrics. It uses knitting needles to form coils of yarns of various raw materials and varieties, and then connects them into knitted fabrics through stringing. It is mainly composed of a frame, a yarn supply 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 rolled into bundles by the cloth winding mechanism of the knitting weft knitting machine. Because more than one type of yarn is used when weaving the fabric, and the elasticity of each yarn is different, when the fabric is wound after weaving, the edge of the fabric will naturally curl, affecting the flatness of the rolled fabric. Therefore, it is necessary to use the edge stripping module to strip the edges of the fabric at both ends of the horizontal cloth so that the cloth winding roller can wind the cloth smoothly.

[0003] For example, the patent with publication number CN118220888A mainly peels the cloth by the belt on the stripping wheel. However, when stripping the edges of knitted textile fabrics that are easy to curl and have severe curling, due to the severe curling of the fabric, during the stripping process, due to the high elasticity of the fabric yarn, the fabric will rebound. That is, after the fabric is stripped by the belt, part of the fabric will rebound. The fabric rebound will make the stripping difficult to control and the stripping will be incomplete. Summary of the invention

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

[0005] The object of the present invention can be achieved by the following technical scheme: a stripping and winding device of a weft knitting machine, comprising a base and elastic fabric, a connecting arm is installed on the base, a winding roller is installed on the connecting arm, an adjusting pressure roller and a stripping assembly are respectively installed on the base, the stripping assembly is located between the adjusting pressure rollers, and the elastic fabric passes through the gap between the adjusting pressure roller and the stripping assembly to connect the winding roller; The stripping assembly includes a slide bar and a slide table installed on both sides of the slide bar, slides are installed on both sides of the slide table, vertical plates are installed on the slide table, a rotating cylinder and a power cylinder are rotatably installed on the vertical plates, the rotating cylinder and the power cylinder are connected to the driven block and the active block through a ventilation roller and an active roller respectively, the driven block and the active block are respectively located in the slide table and slidably installed, a push rod is fixedly installed on the active block, the push rod is in contact with the driven block, the driven block is connected to the inner wall of the slide table through a magnetic isolation spring, a limit block is installed on the inner wall of the slide table, a magnetic suction cup is installed on the limit block, the magnetic suction cup absorbs the driven block, a number of belts are installed on the ventilation roller and the active roller, and a motor that drives the active block to slide along the slide table is installed on the slide.

[0006] 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 the screw rod, and the connecting block cooperates with the screw rod in transmission.

[0007] As a further optimization or improvement of the present solution, a motor is installed in 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.

[0008] As a further optimization or improvement of the present scheme, a ventilation groove is provided in the ventilation roller, an air outlet hole is provided in the ventilation groove, the ventilation roller is rotatably connected to the rotating cylinder, a connecting rod is fixedly installed in the ventilation groove, a spiral blade is installed on the connecting rod, an air intake pipe is fixedly installed on the driven block, the air intake pipe is inserted into the ventilation groove, an air intake hole is provided at the bottom of the air intake pipe, the ventilation roller blocks the air intake hole, and the spiral blade is located in the air intake pipe.

[0009] As a further optimization or improvement of this solution, a hole groove is provided in 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 rotationally connected to the power cylinder.

[0010] As a further optimization or improvement of the present solution, the adjusting pressing roller and the belt fit the elastic fabric.

[0011] A method for stripping and rolling cloth of a weft knitting machine, the method is applied to the stripping and rolling cloth device of the weft knitting machine as described above, the method comprises the following steps: Step S1: passing the elastic fabric through the gap between the adjusting pressing roller and the edge stripping assembly and connecting the winding roller; 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 slide groove of the slide table, and at the same time, the active block pushes the driven block to move synchronously with it through the push rod. When the driven block contacts the limit block, the magnetic suction cup on the limit block starts and adsorbs the driven block. At this time, the ventilation roller and the active roller are in an inclined state at the same time, and the belts on them contact the elastic fabric; Step S3: then adjusting the position of the pressing roller so that the belt can be in full contact with the elastic fabric; 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, the ventilation roller is in an inclined state, and the active roller is in a vertical state. The belts at the bottom of the ventilation roller and the active roller are gradually tightened, so that the belts are gradually tightened from top to bottom; Step S5: the power drum drives the active roller to rotate. When the elastic fabric passes through the belt, the stripping force of the belt on the elastic fabric gradually increases. The gradually increasing stripping force of the belt can control the rebound amount of the elastic fabric.

[0012] As a further optimization or improvement of this solution, step S4 specifically includes the following steps: Step S41: when the ventilation roller is adjusted to an inclined state and the driving roller is adjusted to a vertical state, the belts at the bottom of the ventilation roller and the driving roller are gradually tightened, and the air inlet pipe is gradually moved out of the ventilation groove, and the ventilation roller releases the blockage of the air inlet hole; Step S42: When the motor controls the active roller to rotate, the active roller drives the ventilation roller to rotate through the belt, and at this time, the ventilation roller rotates synchronously with the spiral blade; Step S43: The spiral blade rotates to draw external air into the ventilation groove through the air inlet and discharge it from the air outlet.

[0013] Beneficial effects of the present invention: (1) The present invention drives the active block and the driven block to move synchronously through a motor. When the driven block contacts the limit block, the magnetic suction cup on the limit block starts and attracts the driven block. At this time, the ventilation roller and the active roller are in a tilted state at the same time, and the belts thereon contact the elastic fabric. Then, the position of the pressure roller is adjusted so that the belt can contact the elastic fabric completely. Then, by controlling the motor to reverse, the motor drives the active block to reset. At this time, the ventilation roller is in a tilted state, and the active roller is in a vertical state. The belts at the bottom of the ventilation roller and the active roller are gradually tightened, so that the belts are gradually tightened from top to bottom.

[0014] If an elastic fabric with severely curled edges passes through the belt, the belt's stripping force on the elastic fabric will gradually increase. The gradually increasing stripping force of the belt can control the amount of elastic fabric rebounding. Combined with the compact design of the belt, it is more conducive to controlling the amount of elastic fabric rebounding and avoiding incomplete stripping.

[0015] (2) When the ventilation roller is adjusted to an inclined state and the active roller is adjusted to a vertical state, the ventilation roller and the belt at the bottom of the active roller are gradually tightened. At this time, the air inlet pipe is gradually moved out of the ventilation groove, and the ventilation roller releases the blockage of the air inlet hole. When the motor controls the active roller to rotate, the active roller drives the ventilation roller to rotate through the belt. At this time, the ventilation roller rotates synchronously with the spiral blade. The rotation of the spiral blade draws external air into the ventilation groove through the air inlet hole and discharges it from the air outlet, thereby realizing the heat dissipation of the belt, so as to avoid the heat generated by the belt from affecting the quality of the elastic fabric.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-Figure 13 A stripping and winding device for a weft knitting machine comprises a base 1 and an elastic fabric 5, a connecting arm 2 is mounted on the base 1, a winding roller 3 is mounted on the connecting arm 2, an adjusting pressing roller 4 and a stripping assembly 6 are mounted on the base 1, the stripping assembly 6 is located between the adjusting pressing rollers 4, and the elastic fabric 5 passes through the gap between the adjusting pressing rollers 4 and the stripping assembly 6 to connect the winding roller 3; The stripping assembly 6 includes a slide bar 601 and a slide table 602 installed on both sides of the slide bar 601, slide tables 608 are installed on both sides of the slide table 602, a vertical plate 604 is installed on the slide table 608, a rotating cylinder 605 and a power cylinder 606 are rotatably installed on the vertical plate 604, the rotating cylinder 605 and the power cylinder 606 are connected to the driven block 611 and the active block 613 through the ventilation roller 615 and the active roller 614 respectively, the driven block 611 and the active block 613 are respectively located in the slide table 608 and slide Dynamic installation, a push rod 612 is fixedly installed on the active block 613, the push rod 612 is in contact with the driven block 611, the driven block 611 is connected to the inner wall of the slide 608 through a magnetic isolation spring 610, a limit block 609 is installed on the inner wall of the slide 608, a magnetic suction cup 619 is installed on the limit block 609, the magnetic suction cup 619 absorbs the driven block 611, a plurality of belts 603 are installed on the ventilation roller 615 and the active roller 614, and a motor 616 for driving the active block 613 to slide along the slide 608 is installed on the slide 608.

[0033] Specifically, the motor 620 is installed in the power cylinder 606 , the output shaft of the motor 620 is connected to the active roller 614 , and the heat dissipation holes 607 are installed on the power cylinder 606 .

[0034] Specifically, the adjusting pressing roller 4 and the belt 603 fit the elastic fabric 5 .

[0035] It should be noted that the yarn is passed through the fabric production assembly to produce the elastic fabric 5, and then the elastic fabric 5 is passed through the gap between the adjusting pressing roller 4 and the edge stripping assembly 6 to connect the winding roller 3. During the process of producing the elastic fabric 5, the winding roller 3 can automatically rotate to realize the fabric winding function.

[0036] When the stripping assembly 6 is in use, see Figure 7 , Fig. 9 and Fig.11, start the motor 616, and 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 internal slide groove of the slide table 608. At the same time, the active block 613 pushes the driven block 611 to move synchronously with it 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 suction cup 619 on the limit block 609 starts and absorbs the driven block 611. At this time, the ventilation roller 615 and the active roller 614 are in an inclined state at the same time, and the belt 603 thereon contacts the elastic fabric 5. Then adjust the position of the pressure roller 4 so that the belt 603 can contact the elastic fabric 5 completely.

[0037] The motor 616 is controlled to reverse, and the motor 616 drives the active block 613 to reset. Since the magnetic suction cup 619 on the limit block 609 fixes the driven block 611, the ventilation roller 615 is in an inclined state and the active roller 614 is in a vertical state. The belts 603 at the bottom of the ventilation roller 615 and the active roller 614 are gradually tightened, so that the belt 603 is gradually tightened from top to bottom.

[0038] See also Figure 6 , start the motor 620 inside the power cylinder 606, and the motor 620 drives the active roller 614 to rotate. If the elastic fabric 5 with severe curling passes between the adjusting pressure roller 4 and the belt 603, the stripping force of the belt 603 on the elastic fabric 5 gradually increases. When the elastic fabric 5 passes through the belt 603, the gradually increased stripping force of the belt 603 can control the rebound amount of the elastic fabric 5 and reduce the rebound amount of the elastic fabric 5. Combined 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 stripping.

[0039] Specifically, in order to more clearly state that the gradually increasing stripping force of the belt 603 can reduce the rebound amount of the elastic fabric 5, the assumption method is adopted 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 strip one curl on the elastic fabric 5 (the rebound amount of the elastic fabric 5 is rebounded on the basis of stripping one curl), and four curls remain on the elastic fabric 5; when the elastic fabric 5 passes through the second group of belts 603, due to the increase in the stripping force of the second group of belts 603, the second group of belts 603 can strip two of the remaining four curls on the elastic fabric 5 (the rebound amount of the elastic fabric 5 is rebounded on the basis of stripping two curls), and successively afterwards, the rebound amount of the elastic fabric 5 is controlled.

[0040] It should be noted that when the elasticity of the fabric yarn is large, the distance between the winding roller 3 and the stripping assembly 6 can be appropriately shortened, which is conducive to the winding of the winding roller 3 and avoids the rebound of the fabric during the winding of the elastic fabric 5 to a certain extent. In actual use, the number of belts 603 is usually set to two or three groups. The number of belts 603 set in the attached drawings of the present invention is to be able to express the state of the ventilation roller 615 and the active roller 614, and is not an actual number standard.

[0041] See also Figure 8-Figure 9 A connecting block 618 is installed on the active block 613 , and the output end of the motor 616 is connected to a screw rod 617 , and the connecting block 618 and the screw rod 617 are matched in transmission.

[0042] 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, so the active roller 614 and the ventilation roller 615 and the belt 603 thereon and other components are set in two groups. At this time, 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, thereby 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 relative to each other.

[0043] See also Figure 10-12 A ventilation groove 6151 is provided in the ventilation roller 615, an air outlet hole 6150 is provided in the ventilation groove 6151, the ventilation roller 615 is rotatably connected to the 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 provided 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.

[0044] Specifically, a hole groove 6140 is provided in the active roller 614 , an insertion rod 6141 is fixedly installed on the active block 613 , the insertion rod 6141 is inserted into the hole groove 6140 , and the active roller 614 is rotatably connected to the power cylinder 606 .

[0045] It should be noted that when the belt 603 at the bottom of the active roller 614 and the ventilation roller 615 is tightened, the friction between the belt 603 and the active roller 614 and the ventilation roller 615 increases, and the heat generated by the belt 603 during operation also increases. The increase in heat generated by the operation of the belt 603 can easily affect the quality of the elastic fabric 5.

[0046] When the present invention is in use, when the ventilation roller 615 is adjusted to an inclined state and the active roller 614 is adjusted to a vertical state, the belt 603 at the bottom of the ventilation roller 615 and the active roller 614 is gradually tightened, see Fig.13At this time, the air inlet pipe 6154 gradually moves out of the ventilation groove 6151, and the ventilation roller 615 releases the blockage of the air inlet hole 6155. When the motor 620 controls the active roller 614 to rotate, the active roller 614 drives the ventilation roller 615 to rotate through the belt 603. At this time, the ventilation roller 615 and the spiral blade 6153 rotate synchronously. 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 6150, thereby realizing the heat dissipation of the belt 603, so as to avoid the heat generated by the work of the belt 603 affecting the quality of the elastic fabric 5.

[0047] It should be noted that the spiral blades 6153 can be replaced with fan blades to improve the ventilation efficiency of the air outlet 6150.

[0048] See also Figure 3-Figure 12 As shown, the present invention is a method for stripping and rolling cloth of a weft knitting machine, and the method is applied to the stripping and rolling cloth device of the weft knitting machine as described in the above embodiment, and the method comprises the following steps: Step S1: passing the elastic fabric 5 through the gap between the adjusting pressing roller 4 and the edge stripping assembly 6 and connecting the winding roller 3; Step S2: 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 groove of the slide 608. At the same time, the active block 613 pushes the driven block 611 to move synchronously with it through the push rod 612. When the driven block 611 contacts the limit block 609, the magnetic suction cup 619 on the limit block 609 starts and absorbs the driven block 611. At this time, the ventilation roller 615 and the active roller 614 are in an inclined state at the same time, and the belt 603 thereon contacts the elastic fabric 5. Step S3: then adjust the position of the pressing roller 4 so that the belt 603 can be in full contact with the elastic fabric 5; Step S4: Control the motor 616 to reverse, and the motor 616 drives the active block 613 to reset. Since the magnetic suction cup 619 on the limit block 609 fixes the driven block 611, the ventilation roller 615 is in an inclined state, and the active roller 614 is in a vertical state. The belt 603 at the bottom of the ventilation roller 615 and the active roller 614 is gradually tightened, so that the belt 603 is gradually tightened from top to bottom; Step S5: the power cylinder 606 drives the active roller 614 to rotate. When the elastic fabric 5 passes through the belt 603 , the stripping force of the belt 603 on the elastic fabric 5 gradually increases. The gradually increasing stripping force of the belt 603 can control the rebound amount of the elastic fabric 5 .

[0049] like Figure 6-Figure 13 As shown, as a preferred embodiment of the present invention, step S4 specifically includes the following steps: Step S41: When the ventilation roller 615 is adjusted to an inclined state and the active roller 614 is adjusted to a vertical state, the ventilation roller 615 and the belt 603 at the bottom of the active roller 614 are gradually tightened, and the air inlet pipe 6154 is gradually moved out of the ventilation groove 6151, and the ventilation roller 615 releases the blockage of the air inlet hole 6155; Step S42: When the motor 620 controls the active roller 614 to rotate, the active roller 614 drives the ventilation roller 615 to rotate through the belt 603. At this time, the ventilation roller 615 and the spiral blade 6153 rotate synchronously; Step S43 : The spiral blade 6153 rotates to draw external air into the ventilation groove 6151 through the air inlet 6155 and discharge it from the air outlet 6150 .

[0050] The implementation principle of the present invention is: When using, see Figure 7 , Fig. 9 and Fig.11 , start the motor 616, and 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 internal slide groove of the slide table 608. At the same time, the active block 613 pushes the driven block 611 to move synchronously with it 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 suction cup 619 on the limit block 609 starts and absorbs the driven block 611. At this time, the ventilation roller 615 and the active roller 614 are in an inclined state at the same time, and the belt 603 thereon contacts the elastic fabric 5. Then adjust the position of the pressure roller 4 so that the belt 603 can contact the elastic fabric 5 completely.

[0051] The motor 616 is controlled to reverse, and the motor 616 drives the active block 613 to reset. Since the magnetic suction cup 619 on the limit block 609 fixes the driven block 611, the ventilation roller 615 is in an inclined state, and the active roller 614 is in a vertical state. The belt 603 at the bottom of the ventilation roller 615 and the active 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 is gradually moved out of the ventilation groove 6151, and the ventilation roller 615 is released from the air inlet hole 6154. 155 is blocked. When the motor 620 controls the active roller 614 to rotate, the active 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 6155 and discharge it from the air outlet 6150, thereby realizing the heat dissipation of the belt 603, so as to avoid the heat generated by the work of the belt 603 from affecting the quality of the elastic fabric 5.

[0052] If the elastic fabric 5 with severe curling passes between the adjusting pressure roller 4 and the belt 603, the stripping force of the belt 603 on the elastic fabric 5 will gradually increase. When the elastic fabric 5 passes through the belt 603, the gradually increased stripping force of the belt 603 can control the rebound amount of the elastic fabric 5. Combined 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 stripping.

[0053] 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 to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.

7. A method for stripping and rolling cloth of a weft knitting machine, characterized in that: The method is applied to the edge stripping and cloth rolling device of the weft knitting machine as described in any one of claims 1 to 6 above, and the method comprises the following steps: Step S1: passing the elastic fabric (5) through the gap between the adjusting pressing roller (4) and the edge stripping assembly (6) and connecting the winding roller (3); Step S2: the motor (616) drives the connecting block (618) and the active block (613) to move synchronously via the screw rod (617). At this time, the active block (613) moves along the inner groove of the slide table (608). At the same time, the active block (613) pushes the driven block (611) to move synchronously with it via the push rod (612). When the driven block (611) contacts the limit block (609), the magnetic suction cup (619) on the limit block (609) starts and absorbs the driven block (611). At this time, the ventilation roller (615) and the active roller (614) are in an inclined state at the same time, and the belt (603) thereon contacts the elastic fabric (5); Step S3: then adjusting the position of the pressure roller (4) so ​​that the belt (603) can be in full contact with the elastic fabric (5); Step S4: Control the motor (616) to reverse, and the motor (616) drives the active block (613) to reset. Since the magnetic suction cup (619) on the limit block (609) fixes the driven block (611), the ventilation roller (615) is in an inclined state, and the active roller (614) is in a vertical state. The belts (603) at the bottom of the ventilation roller (615) and the active roller (614) are gradually tightened, so that the belt (603) is gradually tightened from top to bottom; Step S5: the power cylinder (606) drives the active roller (614) to rotate. When the elastic fabric (5) passes through the belt (603), the stripping force of the belt (603) on the elastic fabric (5) gradually increases. The gradually increasing stripping force of the belt (603) can control the rebound amount of the elastic fabric (5).
