Description

Technical Field

[0001] The present invention relates to a dipping device, especially a dipping device for textile fabrics. Background Art

[0002] The technological process of dipping is a common dyeing technique, often used in the dyeing process of textiles and clothing. Its basic principle is to soak the textile fabric in a liquid containing dyes, enabling interaction between the textile fabric and dye molecules to achieve the purpose of dyeing. In the actual dipping process, to achieve continuous dyeing production, generally a unwinding roller is set at the head end of the dipping tank, and a winding roller is set at the tail end of the dipping tank. Through the cooperation of winding and unwinding operations, continuous dipping of the rolled fabric is realized. Some can also add a cleaning tank or / and a drying box between the winding roller and the unwinding roller, enabling the cleaning and drying operations to be completed before winding. Or multiple dyeing tanks are added to enable synchronous dyeing of multiple fabrics, thereby improving the dyeing effect, such as a one-piece multi-color dipping device with good dyeing effect for clothing fabrics (publication number: CN112251946B).

[0003] However, in the above-mentioned prior art solutions, when a roll of fabric is completely unwound, it takes a lot of manpower to replace the new winding roller and unwinding roller. Moreover, the first section of the fabric on the new unwinding roller needs to be manually passed through the dyeing tank, cleaning tank, and drying box and fixed on the unwinding roller. Especially for a dipping device with synchronous dyeing of multiple colors as shown in a one-piece multi-color dipping device with good dyeing effect for clothing fabrics (publication number: CN112251946B), generally when replacing the old and new winding and unwinding, and passing the first section of the new unwinding roller through the dyeing tank, cleaning tank, and drying box and fixing it on the winding roller, it is more time-consuming and laborious. Especially in a large workshop with a dyeing tank, a cleaning tank, and multiple groups of dyeing tanks operating synchronously, the sizes of the dyeing tank, cleaning tank, and drying box are generally large. When manually driving the first section of the fabric through the dyeing tank, cleaning tank, and drying box, there is a risk of falling into the tank, so the danger is greater. Summary of the Invention

[0004] To solve the above technical problems, the purpose of the present invention is to provide a dipping device for textile fabrics. By rearranging the positions of the dyeing tank, cleaning tank, drying box, unwinding roller, and winding roller, synchronous dyeing of multiple colors can be achieved in a large production workshop. At the same time, the replacement time of the old and new rollers can be shortened, and manual operation is not only time-saving and labor-saving, but also safer.

[0005] The present invention provides the following technical solutions:

[0006] A textile fabric dyeing and impregnating device includes two groups of protective side frames arranged side by side vertically. This protective side frame is a protective vertical wall structure, which can not only play the role of delimiting and protecting the production area to prevent operators from accidentally entering the dyeing pool and the cleaning pool, but also provide support for the reciprocating sliding of the subsequent drying unit. There are multiple groups of production units arranged side by side horizontally between the two groups of protective side frames. Each group of production units has a group of dyeing pools and cleaning pools distributed longitudinally. Therefore, multiple groups of dyeing can be carried out synchronously between the two groups of protective side frames. And there are loading and unloading and trimming areas reserved between adjacent two groups of production units and at both edges of the horizontally arranged production units. Above the production units, there is a drying unit slidably connected horizontally between the two groups of protective side frames. The drying unit is provided with drying boxes corresponding to twice the number of production units. The drying unit reciprocates under the drive of a horizontal driving member, so that the drying boxes slide reciprocally and alternately above the corresponding production units. Therefore, when half of the drying boxes move above the corresponding production units to cooperate with the integrated operation of dyeing, cleaning and drying, the other drying boxes can be corresponding in the loading and unloading and trimming areas;

[0007] At the bottom side of each group of drying boxes, a set of unwinding rollers is distributed and installed, and at the top side, a set of winding rollers is correspondingly installed. The textile fabric unwound by the unwinding roller is pressed by a top pressure roller installed on the frame of the drying unit into the dyeing pool and the cleaning pool, and after being redirected by a redirecting roller installed on the frame of the drying unit, it passes through the drying box and is wound and fixed on the winding roller. Therefore, in the loading and unloading and trimming areas, the replacement or trimming and maintenance operations of the winding rollers and the unwinding rollers can be carried out. At this time, half of the drying boxes cooperate with the integrated production operation of dyeing, cleaning and drying, while for the unwinding rollers and winding rollers corresponding to the other half of the drying boxes, the winding rollers that have completed winding are replaced with new winding rollers, and the unwinding rollers that have completed unwinding and the new unwinding rollers are replaced. At the same time, the first section of the textile fabric of the unwinding roller can pass through the drying box and be fixed on the winding roller. Subsequently, during the new round of alternation, after the whole drying unit linearly and horizontally moves a fixed distance, the top pressure roller presses the textile fabric into the dyeing pool and the cleaning pool, the unwinding roller unwinds, and the winding roller winds. Then, the integrated operation of dyeing, cleaning and drying can be realized. The alternation time is relatively short, so the production waiting time can be greatly saved. And the arrangement of the drying boxes above the dyeing pool and the cleaning pool can also save the occupied space of the equipment plane, making it possible to better utilize the three-dimensional upper space of the factory building.

[0008] Preferably, a pair of clamping rods are further arranged in the drying box. The short shafts at both ends of the clamping rods are slidably installed on a set of lifting frames respectively. A clamping screw rod screwed into the short shafts at both ends of the clamping rods is further installed in the lifting frames. The clamping screw rod is driven to rotate by a clamping motor for driving the two clamping rods to clamp the textile fabric towards each other or loosen the fabric away from each other. A set of lifting blocks are further arranged on the outer side of the lifting frames. The lifting blocks are slidably installed in the box body of the drying box, and a set of lifting screw rods are screwed into the lifting blocks. The lifting screw rods are driven to rotate by a lifting motor for driving the lifting frames to drive the two clamping rods to reciprocate between the inlet and the outlet of the drying box.

[0009] Preferably, lower through openings for the feeding roller trolley to pass through are formed in the protective side frames on both sides of the loading and unloading trimming area. The feeding roller trolley transports the unwinding roller and enters from the lower through opening on the side close to the winding roller. When it is transported below the inlet of the drying box, the first section of the fabric on the unwinding roller is clamped between the clamping rods that slide to the inlet of the drying box. After the clamping rods clamp the first section of the fabric, they then drive the first section of the fabric to move towards the outlet of the drying box, thus eliminating the need for manual adjustment of the fabric passing through the drying box. At the same time, the feeding roller trolley drives the unwinding roller to move to the unwinding position for fixed installation of the unwinding roller, and the operator only needs to fix the first section of the fabric moving to the outlet of the drying box on the winding roller, which is more time-saving and labor-saving.

[0010] Preferably, at the unwinding position, the unwinding roller is installed on the frame body of the drying group unit through the automatic positioning part one to achieve a relatively high degree of automation in the up-and-down roller operation of the unwinding roller, thus making the operation of personnel more time-saving and labor-saving. The automatic positioning part one includes two sliding blocks one slidably installed on the frame body of the drying group unit. The bottom sides of the two sliding blocks one are each supported by a set of support frames one. A positioning cylinder one for driving the two sliding blocks one to move towards each other and positioning the unwinding roller through the connecting part one is further installed on the two support frames one. The connecting part one includes a connecting clamping jaw one, a fixing block one, a rotating block one, and a rotating motor one. Two end block shafts one are provided at both ends of the unwinding roller. A rotating ring one is rotatably installed outside the end block shafts one. The clamping jaw driving cylinder of the connecting clamping jaw one is installed on the frame body of the drying group unit, and the connecting clamping jaw one is provided with two arc-shaped claw bodies one for clamping and holding outside the rotating ring one. The fixing block one is fixedly installed on one sliding block one, the rotating block one is rotatably installed on the other sliding block one, and is driven to rotate by the rotating motor one. The ends of the fixing block one and the rotating block one are rectangular blocks for cooperating with the rectangular grooves at the ends of the end block shafts one. Two jacking cylinders are installed on the feeding roller trolley, and the driving ends of the two jacking cylinders are fixed with arc-shaped support blocks one for supporting the bottom side of the rotating ring one;

[0011] Based on the above structure of the automatic positioning part 1, both ends of the unwinding roller are placed on the arc-shaped support block 1 through the rotating ring 1. After the feeding roller trolley drives the unwinding roller to enter through the lower through-port on the side close to the winding roller, and the clamping rod clamps the head end of the textile fabric, the feeding roller trolley moves towards the unwinding position, and the clamping rod moves towards the outlet of the drying box. The rotating ring 1 can play a role in positioning and supporting. The unwinding roller can not only move linearly with the feeding roller trolley, but also rotate during the pulling process of the first section of the fabric. When the feeding roller trolley moves to the unwinding position, the lifting cylinder can support the unwinding roller through the arc-shaped support block 1 and rise to the clamping range of the connecting clamp 1. After the connecting clamp 1 clamps the rotating ring 1 to achieve the preliminary positioning of the unwinding roller, the fixing block 1 and the rotating block 1 can be butted into the end rectangular groove of the end block shaft 1 during the opposite movement of the two groups of sliding blocks 1. If unwinding is required, it can be driven by the connection between the rotating motor 1 and the rotating block 1 to ensure the accuracy of unwinding. During this process, manual operation only needs to participate in simple alignment, which is relatively labor-saving and time-saving. Similarly, when the unwinding is completed, after the drying group unit is replaced and alternated under the drive of the transverse drive member, the feeding roller trolley can support the unwinding roller with the connecting clamp 1 loosened and leave through the lower channel port on the side far from the winding roller, and the production continuity is relatively good.

[0012] Preferably, in order to ensure that the feeding roller trolley can walk in a straight line, a linear track for limiting the walking wheels of the feeding roller trolley is also provided on the horizontal plane of the loading and unloading trimming area.

[0013] Preferably, upper through-ports for the feeding roller crane to pass through are also opened on the protective side frames on both sides of the loading and unloading trimming area. The feeding roller crane is used to convey the winding roller to enter through the upper through-port and move to the winding position above the outlet of the drying box;

[0014] At the winding position, the winding roller is installed on the frame of the drying group unit through the automatic positioning part 2 to achieve a higher degree of automation of the upper and lower roller operations of the winding roller, thus making the personnel operation more labor-saving and time-saving. The automatic positioning part 2 includes two groups of sliding blocks 2 slidably installed on the frame of the drying group unit. The top sides of the two groups of sliding blocks 2 are each limited and supported by a support frame 2, and a positioning cylinder 2 for driving the two groups of sliding blocks 2 to move towards each other and positioning the winding roller through the connecting member 2 is also installed on the two support frames 2. The connecting member 2 includes a U-shaped support member, a fixing block 2, a rotating block 2, and a rotating motor 2. Both ends of the winding roller have two groups of end block shafts 2, and a rotating ring 2 is rotatably installed outside the end block shafts 2. There are two groups of U-shaped support members, which are correspondingly located at the bottom side of the rotating ring 2, and their two sides are limited and supported outside the rotating ring 2, and a lifting cylinder is installed on their bottom sides. The driving end of the lifting cylinder is installed with an arc-shaped support block 2, and the arc-shaped support block 2 is used to lift the winding roller towards the feeding roller crane direction through the rotating ring 2;

[0015] The said roller feeding crane includes a fixed top plate connected between two groups of protective side frames, a crane top plate slidably connected to the fixed top plate and driven to reciprocate by a longitudinal driving cylinder, and two groups of connecting clamps II installed on the crane top plate. The jaw driving cylinder of the connecting clamp II is installed on the crane top plate, and the connecting clamp II is provided with two groups of arc-shaped claw bodies II for clamping and holding the outer part of the rotating ring II;

[0016] The second fixed block is fixedly installed on one group of second sliding blocks, the second rotating block is rotatably installed on the other group of second sliding blocks, and is driven to rotate by a second rotating motor. The ends of the second fixed block and the second rotating block are also rectangular blocks for cooperating with the end rectangular grooves of the second end block shaft;

[0017] Based on the above structure of the automatic positioning part II, the connecting clamp II of the roller feeding crane can be clamped at the rotating ring II at both ends of the winding roller, and under the drive of the longitudinal driving cylinder, it slides to the winding position. At this time, the top cylinder in the U-shaped support member drives the arc-shaped support block II to rise until it contacts the upper rotating ring II. The connecting clamp II relaxes, and the top cylinder descends again to place the rotating ring II in the U-shaped support member. Furthermore, the second fixed block and the second rotating block can be butted into the end rectangular grooves of the second end block shaft during the opposite movement of the two groups of second sliding blocks. If winding is to be carried out, it can be driven by the connection between the second rotating motor and the second rotating block. In this process, manual operation only needs to participate in simple alignment, which is relatively labor-saving and time-saving. Similarly, when the winding is completed, after the drying group unit is transposed and alternated under the drive of the transverse driving member, the roller feeding crane clamps the winding roller supported by the U-shaped support member and leaves through the upper channel opening to start a new round of cycle, and the production continuity is relatively good.

[0018] Preferably, there are at least two top pressure rollers I above the dyeing tank, and at least one auxiliary roller is also installed at the bottom of the dyeing tank between the top pressure rollers I, so as to extend the length of the textile fabric soaked in the dyeing tank at one time. The two ends of the top pressure roller I are installed on two groups of first mounting frames, and the two groups of first mounting frames are driven by two groups of first top pressure cylinders installed on the frame of the drying group unit to be pressed into the dyeing tank or the cleaning tank. The two ends of the auxiliary roller are installed in the dyeing tank through a fixed frame.

[0019] Preferably, a top pressure roller II is also installed in the drying box. The two ends of the top pressure roller II are installed on two groups of second mounting frames, and the two groups of second mounting frames are driven by two groups of second top pressure cylinders installed on the side walls of the drying box to press the textile fabric between the inlet and the outlet of the drying box, so as to extend the length of the textile fabric dried in the drying box at one time, thereby reducing the height of the drying box.

[0020] Preferably, two top support rollers are also distributed at the tops of the dyeing tank and the cleaning tank to redirect and limit the textile fabric pressed by the top pressure roller I, and to prevent the textile fabric from scraping the top side walls of the dyeing tank and the cleaning tank.

[0021] The beneficial effects of the present invention are:

[0022] 1. Since the dyeing tank and the cleaning tank are arranged side by side in the length direction, and the drying oven is arranged above the dyeing tank and the cleaning tank, the floor space of the drying operation equipment plane can be saved, and the three-dimensional upper space of the factory building can be better utilized;

[0023] 2. Since the drying oven is set to be a structure that can be adjusted and moved horizontally relative to the dyeing tank and the cleaning tank, and the winding roller and the unwinding roller are arranged on the drying oven, when the roll needs to be changed, the drying oven can be moved to move the winding roller and the unwinding roller on it away from the corresponding dyeing tank and cleaning tank. When manual replacement is carried out, it can also be away from the dyeing tank and the cleaning tank, thereby improving safety;

[0024] 3. By setting multiple groups of dyeing tanks and cleaning tanks, each group of dyeing tanks and cleaning tanks forms a production unit. The production units are arranged side by side, and both sides of each production unit are separated by a set of loading and unloading and trimming areas. At the same time, the number of drying ovens is twice the number of production units, and all drying ovens are combined into an integrated drying group unit. Therefore, when half of the drying ovens are moved above the corresponding production units to cooperate with the integrated operations of dyeing, cleaning, and drying, the other half of the drying ovens are corresponding in the loading and unloading and trimming areas. In the loading and unloading and trimming areas, the replacement or trimming and maintenance operations of the winding roller and the unwinding roller can be carried out. At this time, the replacement or correction and maintenance operations can be synchronized with the dyeing, cleaning, and drying. After the trimming is completed, it can be statically waiting for the alternation of the drying group unit. And when alternating, only a short distance of linear movement of the drying group unit is required to complete the alternation of multiple groups, thereby greatly saving the production waiting time;

[0025] 4. Since the unwinding roller, the tensioning roller, and the winding roller are all distributed on the drying oven, and there are fewer rollers arranged in the dyeing tank and the cleaning tank, it is more convenient to clean the dyeing tank and the cleaning tank;

[0026] 5. By setting a pair of clamping rods in the drying oven, the clamping rods can clamp the fabric and slide linearly from the inlet of the drying oven to the outlet of the drying oven, and lower through openings are opened on the protective side frames on both sides of the loading and unloading and trimming areas. Therefore, when the feeding roller cart transports the unwinding roller through the lower through opening and enters below the inlet of the drying oven, the operator only needs to clamp the first section of the fabric on the unwinding roller between the clamping rods sliding to the inlet of the drying oven, and the clamping rods can drive the first section of the fabric to move upward to the outlet of the drying oven above, without the operator adjusting the fabric to pass through the drying oven. At the same time, the feeding roller cart drives the unwinding roller to move to the unwinding position for the fixed installation of the unwinding roller, and the operator only needs to fix the first section of the fabric moving to the outlet of the drying oven on the winding roller, which is time-saving and labor-saving. And upper through openings can also be arranged on both sides of the loading and unloading and trimming areas, and the winding roller can be automatically fixed and installed through the upper through openings arranged on both sides of the loading and unloading and trimming areas, which is more convenient.

[0043] Embodiment 1

[0044] As Figure 1-4 shown, a textile fabric dyeing equipment. In this embodiment, it includes two groups of protective side frames 1 arranged side by side vertically. This protective side frame 1 is a protective vertical wall structure, which can not only play the role of delimiting and protecting the production area, avoiding operators from straying into the dyeing tank 22 and the cleaning tank 21, but also provide support for the reciprocating sliding of the subsequent drying group unit 4. Between the two groups of protective side frames 1, multiple groups of production units 2 are arranged side by side horizontally. Each group of production units 2 has a group of dyeing tanks 22 and cleaning tanks 21 distributed longitudinally. Therefore, multiple groups of dyeing can be carried out synchronously between the two groups of protective side frames 1. And there are feeding and trimming areas 3 reserved at both ends of the edges of adjacent two groups of production units 2 and the horizontally arranged production units 2. Above the production unit 2, there is a drying group unit 4 slidably connected horizontally between the two groups of protective side frames 1. In the drying group unit 4, drying boxes 41 corresponding to twice the number of production units 2 are provided. The drying group unit 4 reciprocates under the drive of the horizontal driving member 42, so that the drying boxes 41 reciprocally and alternately slide above the corresponding production units 2. Therefore, when half of the drying boxes 41 move above the corresponding production units 2 to cooperate with the integrated operation of dyeing, cleaning, and drying, the other drying boxes 41 can correspond to the feeding and trimming areas 3. And the horizontal driving member 42 here can use a horizontal motor to drive the horizontal lead screw to rotate, so as to drive the sliding blocks on both sides of the drying group unit 4 to reciprocate.

[0045] At the bottom side of each drying oven 41, a set of unwinding rollers 5 is distributed and installed, and at the top side thereof, a set of winding rollers 6 is correspondingly installed. The textile fabric unwound from the unwinding roller 5 is pressed by a first top pressure roller 7 installed on the frame of the drying unit 4 into the dyeing tank 22 and the cleaning tank 21, and after being redirected by a redirecting roller 8 installed on the frame of the drying unit 4, it passes through the drying oven 41 and is wound and fixed on the winding roller 6. Therefore, in the loading and unloading and trimming area 3, the winding roller 6 and the unwinding roller 5 can be replaced or trimmed and maintained. At this time, half of the drying ovens 41 cooperate to perform the integrated production operations of dyeing, cleaning, and drying, while for the unwinding rollers 5 and winding rollers 6 corresponding to the other half of the drying ovens 41, the winding roller 6 that has completed winding is replaced with a new winding roller 6, and the unwinding roller 5 that has completed unwinding and a new unwinding roller 5 are replaced. At the same time, the first section of the textile fabric on the unwinding roller 5 can pass through the drying oven 41 and be fixed on the winding roller 6. Subsequently, during the next round of alternation, after the drying unit 4 as a whole linearly moves horizontally by a fixed distance, the first top pressure roller 7 presses the textile fabric into the dyeing tank 22 and the cleaning tank 21, the unwinding roller 5 unwinds, and the winding roller 6 winds. Then, the integrated operations of dyeing, cleaning, and drying can be achieved. The alternation time is short, so the production waiting time can be greatly saved. Moreover, the arrangement of the drying ovens 41 above the dyeing tank 22 and the cleaning tank 21 can also save the occupied space of the equipment plane, enabling better utilization of the three-dimensional upper space of the factory building.

[0046] A pair of clamping rods 9 are further arranged in the drying oven 41. The short shafts at both ends of the clamping rods 9 are respectively slidably installed on a set of lifting frames 91. A clamping screw rod 92 screwed into the short shafts at both ends of the clamping rods 9 is further installed in the lifting frames 91. The clamping screw rod 92 is driven to rotate by a clamping motor 93 for driving the two clamping rods 9 to clamp the textile fabric towards each other or relax the fabric away from each other. A set of lifting blocks 94 are further arranged on the outer side of the lifting frames 91. The lifting blocks 94 are slidably installed in the box body of the drying oven 41. A set of lifting screw rods 95 are screwed into the lifting blocks 94. The lifting screw rods 95 are driven to rotate by a lifting motor for driving the lifting frames 91 to drive the two clamping rods 9 to reciprocate between the inlet and the outlet of the drying oven 41.

[0047] Lower through openings 10 for the feeding roller trolley 12 to pass through are opened on the protective side frames 1 on both sides of the loading and unloading and trimming area 3. The feeding roller trolley 12 conveys the unwinding roller 5 and enters through the lower through opening 10 on the side close to the winding roller 6. When it is conveyed below the inlet of the drying oven 41, the first section of the fabric on the unwinding roller 5 is clamped between the clamping rods 9 that slide to the inlet of the drying oven 41. After the clamping rods 9 clamp the first section of the fabric, they then drive the first section of the fabric to move towards the outlet of the drying oven 41, so that there is no need for manual adjustment of the fabric to pass through the drying oven 41. At the same time, the feeding roller trolley 12 drives the unwinding roller 5 to move to the unwinding position for the fixed installation of the unwinding roller 5, and the operator only needs to fix the first section of the fabric that moves to the outlet of the drying oven 41 on the winding roller 6, which is time-saving and labor-saving.

[0048] There are at least two sets of top pressure rollers 7 above the dyeing pool 22, and at least one set of auxiliary rollers 14 is installed at the bottom of the dyeing pool 22 between the top pressure rollers 7, so as to extend the length of the textile fabric soaked in the dyeing pool 22 at one time. The two ends of the top pressure roller 7 are installed on two sets of first mounting frames, and the two sets of first mounting frames are driven by two sets of first top pressure cylinders installed on the frame of the drying unit 4 to be pressed into the dyeing pool 22 or the cleaning pool 21. The two ends of the auxiliary roller 14 are installed in the dyeing pool 22 through a fixing frame.

[0049] There is also a top pressure roller 15 installed in the drying box 41. The two ends of the top pressure roller 15 are installed on two sets of second mounting frames, and the two sets of second mounting frames are driven by two sets of second top pressure cylinders installed on the side walls of the drying box 41 to press the textile fabric between the inlet and outlet of the drying box 41, so as to extend the length of the textile fabric dried in the drying box 41 at one time, thereby reducing the height of the drying box 41.

[0050] There are also two sets of top support rollers 16 distributed at the top of the dyeing pool 22 and the cleaning pool 21, so as to deflect and limit the textile fabric pressed by the top pressure roller 7 to prevent the textile fabric from scraping the top side walls of the dyeing pool 22 and the cleaning pool 21.

[0051] Embodiment 2

[0052] As Figure 5-7 shown, a textile fabric dipping device, in this embodiment, is a further limitation based on Embodiment 1. At the unwinding position, a unwinding roller 5 is installed on the frame of the drying unit 4 through an automatic positioning member 17 to realize the up and down roller operation of the unwinding roller 5 with a high degree of automation, thus making the personnel operation more time-saving and labor-saving. The automatic positioning member 17 includes two sets of sliding blocks 171 slidably installed on the frame of the drying unit 4. The bottom sides of the two sets of sliding blocks 171 are each supported by a set of support frames 172, and a positioning cylinder 173 for driving the two sets of sliding blocks 171 to move towards each other and positioning the unwinding roller 5 through a connecting member is also installed on the two sets of support frames 172. The connecting member 1 includes a connecting clamp 174, a fixing block 175, a rotating block 176, and a rotating motor 177. The two ends of the unwinding roller 5 have two sets of end block shafts 178, and a rotating ring 179 is externally connected and installed on the end block shaft 178. The jaw driving cylinder of the connecting clamp 174 is installed on the frame of the drying unit 4, and the connecting clamp 174 is provided with two arc-shaped claw bodies for clamping and holding the outside of the rotating ring 179. The fixing block 175 is fixedly installed on one set of sliding blocks 171, the rotating block 176 is rotatably installed on the other set of sliding blocks 171, and is driven to rotate by the rotating motor 177. The ends of the fixing block 175 and the rotating block 176 are rectangular blocks for cooperating with the rectangular grooves at the ends of the end block shaft 178. Two sets of lifting cylinders are installed on the feeding roller trolley 12, and the driving ends of the two sets of lifting cylinders are fixed with arc-shaped support blocks 1 for supporting the bottom side of the rotating ring 179.

[0053] And in order to ensure that the roller feeding trolley 12 can travel in a straight line, a straight track 19 for limiting the traveling wheels of the roller feeding trolley 12 is provided on the horizontal plane of the loading and unloading trimming area 3.

[0054] Upper passing openings 11 for the roller feeding crane 13 to pass through are also provided on the protective side frames 1 on both sides of the loading and unloading trimming area 3. The roller feeding crane 13 is used to convey the winding roller 6 to enter through the upper passing openings 11 and move to the winding position above the outlet of the drying box 41.

[0055] At the winding position, the winding roller 6 is installed on the frame of the drying group unit 4 through the automatic positioning part two 18 to realize the up-and-down roller operation of the winding roller 6 with a high degree of automation, so that the operation of personnel is more time-saving and labor-saving. The automatic positioning part two 18 includes two sliding blocks two 181 slidably installed on the frame of the drying group unit 4. The top sides of the two sliding blocks two 181 are each limited and supported by a support frame two 182. And a positioning cylinder two 183 for driving the two sliding blocks two 181 to move towards each other and positioning the winding roller 6 through the connecting part two is also installed on the two support frames two 182. The connecting part two includes a U-shaped support part 184, a fixed block two 185, a rotating block two 186, and a rotating motor two 187. Both ends of the winding roller 6 have two end block shafts two 188. A rotating ring two 189 is installed outside the end block shaft two 188 by means of rotation. There are two U-shaped support parts 184, and they are correspondingly located at the bottom side of the rotating ring two 189. Their two sides are limited and supported outside the rotating ring two 189, and a top cylinder is installed on their bottom side. The driving end of the top cylinder is installed with an arc-shaped support block two, and the arc-shaped support block two is used to lift the winding roller 6 towards the roller feeding crane 13 through the rotating ring two 189.

[0056] The roller feeding crane 13 includes a fixed top plate 131 connected between the two protective side frames 1, a crane top plate 132 slidably connected to the fixed top plate 131 and driven to move back and forth by a longitudinal driving cylinder, and two connecting clamping parts two 133 installed on the crane top plate 132. The jaw driving cylinder of the connecting clamping part two 133 is installed on the crane top plate 132, and the connecting clamping part two 133 is provided with two arc-shaped claw bodies two for clamping and holding outside the rotating ring two 189.

[0057] The fixed block two 185 is fixedly installed on one sliding block two 181, the rotating block two 186 is rotatably installed on the other sliding block two 181 and is driven to rotate by the rotating motor two 187. The ends of the fixed block two 185 and the rotating block two 186 are also rectangular blocks for cooperating with the rectangular grooves at the ends of the end block shaft two 188.

[0058] The working principle of the present invention is:

[0059] Based on the above structure of the automatic positioning part one 17, both ends of the unwinding roller 5 are placed on the arc-shaped supporting block one through the rotating ring one 179. After the feeding roller trolley 12 drives the unwinding roller 5 to enter through the lower through-port 10 on the side close to the winding roller 6, and the clamping rod 9 clamps the head end of the textile fabric, the feeding roller trolley 12 moves towards the unwinding position, and the clamping rod 9 moves towards the outlet of the drying box 41. The rotating ring one 179 can play a role in positioning and supporting. The unwinding roller 5 can move linearly with the feeding roller trolley 12 while rotating during the pulling process of the first-section fabric. When the feeding roller trolley 12 moves to the unwinding position, the lifting cylinder can support the unwinding roller 5 to rise through the arc-shaped supporting block one to the clamping range of the connecting clamp one 174. After the connecting clamp one 174 tightly clamps the rotating ring one 179 to achieve the preliminary positioning of the unwinding roller 5, the fixing block one 175 and the rotating block one 176 can be butted into the end rectangular groove of the end block shaft one 178 during the opposite movement of the two groups of sliding blocks one 171. If unwinding is to be carried out, it can be driven by the connection between the rotating motor one 177 and the rotating block one 176 to ensure the accuracy of unwinding. During this process, manual operation only needs to participate in simple alignment, which is relatively labor-saving and time-saving. Similarly, when the unwinding is completed, after the drying group unit 4 is replaced and alternated under the drive of the lateral driving part 42, the feeding roller trolley 12 can support the unwinding roller 5 with the connecting clamp one 174 loosened and leave through the lower channel port on the side far from the winding roller 6, and the production continuity is good;

[0060] Based on the above structure of the automatic positioning part two 18, the connecting clamp two 133 of the feeding roller crane 13 can be clamped at the rotating ring two 189 at both ends of the winding roller 6 and slide to the winding position under the drive of the longitudinal driving cylinder. At this time, the top cylinder in the U-shaped supporting part 184 drives the arc-shaped supporting block two to rise until it touches the upper rotating ring two 189, the connecting clamp two 133 is loosened, and the top cylinder descends again to place the rotating ring two 189 in the U-shaped supporting part 184. Then, the fixing block two 185 and the rotating block two 186 can be butted into the end rectangular groove of the end block shaft two 188 during the opposite movement of the two groups of sliding blocks two 181. If winding is to be carried out, it can be driven by the connection between the rotating motor two 187 and the rotating block two 186. During this process, manual operation only needs to participate in simple alignment, which is relatively labor-saving and time-saving. Similarly, when the winding is completed, after the drying group unit 4 is replaced and alternated under the drive of the lateral driving part 42, the feeding roller crane 13 clamps the winding roller 6 supported by the U-shaped supporting part 184 and leaves through the upper channel port to start a new round of cycle, and the production continuity is good.
