Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of artificial leather production, and particularly relates to a TPEE polyester material ABC three-layer co-extrusion cloth-plastic composite artificial leather preparation device and a preparation process thereof. BACKGROUND

[0002] At present, the traction of artificial leather is fixed. With the traction of artificial leather, the output speed of artificial leather is fast or slow from the glass roller section to the constant tension frame. When the output speed is fast, the speed of the bottom of artificial leather in contact with the surface of the traction roller is fast, which easily causes the traction roller to stop rotating. At this time, the traction effect is reduced, the artificial leather is loose when entering the constant tension frame, and the subsequent winding quality is affected. Therefore, the phenomenon becomes a problem to be solved by people in the field. SUMMARY

[0003] The application aims to provide a TPEE polyester material ABC three-layer co-extrusion cloth-plastic composite artificial leather preparation device and a preparation process thereof, so as to solve the problems in the background.

[0004] In order to solve the above technical problems, the application provides the following technical scheme: a TPEE polyester material ABC three-layer co-extrusion cloth-plastic composite artificial leather preparation device and a preparation process thereof, which comprises a preparation production line, the preparation production line is arranged in a T shape, and comprises a refrigeration water unit, a one-to-three dehumidification vacuum drying machine group, three ABC hoppers, three sets of screw rods, a cloth spreading frame, a rubber roller, a partition integrated distributor, a pattern roller section, a stripping roller section, a traction roller section, an edge cutting device station, an online film surface detector, a flattening and expanding roller, a constant tension frame and a double-station winding inflatable shaft, the double-station winding inflatable shaft has automatic metering and automatic roll changing functions, a screen changer is arranged on each of the three sets of screw rods, and different index raw materials of the three screw rods are input into a special extrusion die through the partition integrated distributor to output a film; the one-to-three dehumidification vacuum drying machine group is connected with the three ABC hoppers through pipelines, the refrigeration water unit is connected with the stripping roller section, the pattern roller section and the rubber roller through pipelines, the pipelines are two, one is a water inlet pipe, and the other is a water outlet pipe, the cloth spreading frame is located on one side of the rubber roller, the edge cutting device station is located on both sides of the traction roller section and is used for cutting and crushing excess edge materials, and the edge cutting device station is connected with the B hopper.

[0005] The present invention further describes that the traction roller section includes two bases and a traction shaft. Support plates are provided on the upper left and right sides of the two bases. A U-shaped groove is provided in the middle of each support plate. A shaft is slidably connected in the U-shaped groove on the right side, and a connecting rod is slidably connected in the U-shaped groove on the left side. A connecting plate is fixedly installed between the shaft and the connecting rod. The traction shaft bearing is installed between the two connecting plates. A motor is fixed on the upper side of the rear base. A disc is fixed on the output end of the motor. A round rod is connected to the surface of the disc. A U-shaped block is fixed on the surface of the connecting plate. The front end of the round rod is inserted into the U-shaped block.

[0006] The present invention further describes that the surface of the disc is provided with a groove, and a slider is slidably connected in the groove. One end of the round rod is fixedly connected to one side of the slider, and a screw is fixed above the slider. A threaded hole is opened on the outer side of the disc, and the screw is threadedly connected in the threaded hole. A nut is fixed at the outer end of the screw.

[0007] The present invention further illustrates that the left end of the connecting rod is inclined, and a protrusion is fixed at the bottom of the U-shaped groove inner wall of the left side support plate, and the upper end of the protrusion is in contact with the inclined part of the connecting rod.

[0008] The present invention further illustrates that a groove is provided on the right side of the connecting rod, and an insertion block is fitted to the inner wall of the groove. A through hole is connected to the left side of the connecting plate and the right end of the connecting rod. A sliding rod is fixed to the right end of the insertion block, and the sliding rod is slidably connected in the through hole. The insertion block is also inclined, and the inclination angle is the same as that of the inclined part of the connecting rod. The edge of the inclined part of the connecting rod is arc-shaped. After the connecting rod moves to the left, the protrusion first contacts the inclined part of the connecting rod, and then contacts the lower surface of the insertion block. The two insertion blocks are fixedly connected.

[0009] The present invention further illustrates that a ball is fixed to the upper end of the nut; a push-pull rod is fixed to one side of the rear insertion block, the right end of the push-pull rod is spherical, after the ball moves to the limit distance outward, the disc rotates again, and the ball contacts the spherical part of the push-pull rod, and the right end of the slide rod is spring-connected to the right side of the inner wall of the through hole.

[0010] The present invention further illustrates that the left side of the connecting rod is provided with a slot, and the insertion block is inserted into the slot after moving; the motor rotates alternately clockwise and counterclockwise, and the rotation angle is fixed at 180 degrees. After the motor rotates 90 degrees and the ball moves to the limit distance outward, the push-pull rod is aligned with the ball, and the protrusion is located at the edge of the inclined part of the connecting rod.

[0011] The present invention further describes the preparation process as follows: Step S1, TPEE material is introduced into a three-stage dehumidification and vacuum drying unit and continuously fed and dried, and then quantitatively and continuously fed into three hoppers A, B, and C based on two-stage hot air drying; Step S2, the material enters the electrically heated screw, and three layers are co-extruded corresponding to the screw, namely, the bottom layer of thermally composite high polarity modified TPEE, the conventional middle layer of TPEE, and the top layer of modified colored TPEE, thereby extruding and molding; Step S3, the extruded material enters the die and the rubber roller step surface, and the chilled water unit adopts a three-stage method to introduce cooling water into the peeling roller section, the patterned roller section, and the rubber roller, while simultaneously introducing polyester fabric to the patterned roller section. In the section and inside the rubber roller, the fabric and film are thermally laminated on the surface of the rubber roller, thus realizing the glue-free lamination and thermal lamination process. This saves one glue lamination process, allows the fabric to be recycled, and is more energy-efficient and environmentally friendly. Step S4: The fabric-plastic patterned artificial leather is directly thermally laminated using the heat energy of the film above 200°C. Step S5: The artificial leather is then pulled by the traction roller section, and the edge material is cut off by the edge cutting device. The edge material is then crushed and sent to the B hopper for recycling through the fan and pipeline. Step S6: The artificial leather is then introduced into the flattening expansion roller to flatten it, and then introduced into the automatic dual-station rewinding air shaft through the constant tension frame. Step S7: Automatic rewinding, online packaging, shelf placement, warehousing, and shipment are completed.

[0012] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: During the traction process of the traction roller section of the present invention for TPEE polyester material ABC three-layer co-extruded fabric-plastic composite artificial leather, the traction shaft is pressed against the bottom surface of the TPEE polyester material ABC three-layer co-extruded fabric-plastic composite artificial leather by the operation of the motor, thereby increasing the traction strength and traction efficiency. Then the motor continues to rotate until the disc rotates 180 degrees and stops, and then reverses to reset. When the disc rotates from 90 degrees to 180 degrees, the connecting plate is moved to the right by the U-shaped block, loosening the TPEE polyester material ABC three-layer co-extruded fabric-plastic composite artificial leather. The tightness is moderate, avoiding the artificial leather from being overstretched and breaking due to continuous high-intensity traction. When the traction strength is too great, the nut is turned in the forward direction to reduce the movement range of the U-shaped block. Conversely, the nut is turned in the reverse direction. The adjustment is convenient and efficient. Moreover, by controlling the traction strength, on the one hand, the traction effect is further improved, and on the other hand, the traction quality of the artificial leather is guaranteed, preventing it from being pulled apart, thus protecting the artificial leather.

[0013] During the process of increasing traction strength, the traction axis lifts the artificial leather to the upper left, raising it and further increasing the traction strength. This effectively prevents the artificial leather from loosening during traction, which could lead to a decrease in subsequent winding quality. When the connecting rod and the protrusion move relative to each other, the artificial leather is lifted slowly, and the process of lifting, releasing, and lifting again provides a controlled relaxation. The traction force on the artificial leather gradually increases and then decreases rapidly, further enhancing the traction quality and effectively preventing the artificial leather from breaking due to excessive stress, thus strengthening the protective effect.

[0027] The following detailed, non-limiting description of the technical solution of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0028] Please see Figures 1-11 This invention provides a technical solution: a TPEE polyester material ABC three-layer co-extrusion fabric-plastic composite artificial leather preparation device and its preparation process, including a preparation production line, characterized in that: the preparation production line is T-shaped and includes a chilled water unit, a one-to-three dehumidification vacuum drying unit, three ABC hoppers, three sets of screws, a fabric spreading frame, rubber rollers, a partition integrated distributor, a patterned roller section, a peeling roller section, a traction roller section, a trimming device station, an online film surface detector, a flattening extension roller, a constant tension frame, and a dual-station winding air shaft. The dual-station winding air shaft has automatic meter counting and automatic roll changing winding functions. Each of the three sets of screws is equipped with a screen changer, and the raw materials with different properties of the three screws are input into a specially designed extrusion die through the partition integrated distributor to produce film.

[0029] The three-in-one dehumidification vacuum dryer unit is connected to the pipes of the three hoppers A, B, and C. The chilled water unit is connected to the peeling roller section, the patterned roller section, and the rubber roller section respectively. There are two pipes, one for water inlet and the other for water outlet. The fabric spreading frame is located on one side of the rubber roller. The edge trimming device is located on both sides of the traction roller section and is used to cut off excess edge material and crush the edge material. The edge trimming device is connected to the B hopper.

[0030] The traction roller section includes two bases 1 and a traction shaft 2. Support plates 3 are provided on the upper left and right sides of the two bases 1. A U-shaped groove is provided in the middle of each support plate 3. A shaft 31 is slidably connected in the right U-shaped groove, and a connecting rod 32 is slidably connected in the left U-shaped groove.

[0031] A connecting plate 33 is fixedly installed between the shaft 31 and the connecting rod 32. The bearing of the traction shaft 2 is installed between the two connecting plates 33. A motor 4 is fixed above the rear base 1. A disc 41 is fixed at the output end of the motor 4. A round rod 42 is connected to the surface of the disc 41. A U-shaped block 331 is fixed to the surface of the connecting plate 33. The front end of the round rod 42 is inserted into the U-shaped block 331.

[0032] Example 1: As Figure 11 and Figure 7 As shown, the TPEE polyester ABC three-layer co-extruded fabric-plastic composite artificial leather moves from the peeling roller section to the traction roller section, and then to the constant tension frame. During this process, the traction roller section provides traction for the TPEE polyester ABC three-layer co-extruded fabric-plastic composite artificial leather. During traction, the operation of motor 4 drives the disc 41 to rotate. The motor 4 rotates counterclockwise, and the disc 41 drives the round rod 42 to rotate counterclockwise around its center. The round rod 42 moves within the U-shaped block 331, causing the U-shaped block 331 to move to the left. The U-shaped block 331 drives the shaft 31 and the connecting rod 32 synchronously through the connecting plate 33. Move to the left, thereby driving the traction shaft 2 to move to the left. At this time, the traction shaft 2 presses against the bottom surface of the TPEE polyester ABC three-layer co-extruded fabric-plastic composite artificial leather, increasing the traction strength and traction efficiency. Then the motor 4 continues to rotate until the disc 41 rotates 180 degrees and stops, and then reverses to reset. When the disc 41 rotates from 90 degrees to 180 degrees, it drives the connecting plate 33 to move to the right through the U-shaped block 331, loosening the TPEE polyester ABC three-layer co-extruded fabric-plastic composite artificial leather. The tightness is moderate, avoiding the artificial leather from being overstretched due to continuous high-intensity traction and thus breaking.

[0033] The surface of the disc 41 is provided with a groove 411, and a slider 412 is slidably connected in the groove 411. One end of the round rod 42 is fixedly connected to one side of the slider 412, and a screw 43 is fixed above the slider 412.

[0034] A threaded hole is provided on the outer side of the disc 41, and the screw 43 is threaded into the threaded hole. A nut is fixed to the outer end of the screw 43.

[0035] Example 2: Figure 8 As shown, the operator tightens the nut, which drives the screw 43 to rotate and move through the threaded hole. The movement of the screw 43 causes the slider 412 to slide within the groove 411, thereby moving the round rod 42. Adjusting the distance between the round rod 42 and the center of the disc 41 changes the eccentric position, thus changing the range of movement of the U-shaped block 331 driven by the round rod 42. When the traction strength is too high, the nut is tightened in the forward direction to reduce the range of movement of the U-shaped block 331; conversely, the nut is tightened in the reverse direction. The adjustment is convenient and efficient. By controlling the traction strength, the traction effect is further improved on the one hand, and the traction quality of the artificial leather is ensured on the other hand, preventing it from being torn and thus protecting the artificial leather.

[0036] The left end of the connecting rod 32 is inclined, and a protrusion 34 is fixed at the bottom of the U-shaped groove of the left side support plate 3, and the upper end of the protrusion 34 is in contact with the inclined part of the connecting rod 32.

[0037] A groove is provided on the right side of the connecting rod 32, and an insertion block 321 is attached to the inner wall of the groove. A through hole is connected to the left side of the connecting plate 33 and the right end of the connecting rod 32. A slide rod 322 is fixed to the right end of the insertion block 321, and the slide rod 322 is slidably connected in the through hole.

[0038] The insertion block 321 is also inclined, and the inclination angle is the same as that of the inclined part of the connecting rod 32. The edge of the inclined part of the connecting rod 32 is arc-shaped. After the connecting rod 32 moves to the left, the protrusion 34 first contacts the inclined part of the connecting rod 32, and then contacts the lower surface of the insertion block 321. The two insertion blocks 321 are fixedly connected.

[0039] Example 3: Figure 9 As shown, in the process of increasing the traction strength in Embodiment 1, the connecting rod 32 moves to the right, and its inclined surface rubs against the upper end of the protrusion 34. It is gradually lifted by the protrusion 34, thereby causing the connecting plate 33 to tilt. The connecting plate 33 drives the traction shaft 2 to lift the artificial leather to the upper left, raising the artificial leather and further increasing the traction strength. This effectively avoids the phenomenon of the artificial leather loosening during the traction process, which would lead to a decrease in the subsequent winding quality. When the connecting rod 32 and the protrusion 34 move relative to each other, the protrusion 34 moves to the edge of the inclined part and continues to move. The connecting rod 32 is affected by the weight of the traction shaft 2, and the protrusion 34 contacts the inclined part of the insertion block 321. The connecting rod 32 descends rapidly, and the traction shaft 2 descends again. The speed of lifting the artificial leather is relatively slow. The lifting and releasing, and then lifting again, plays a role in relaxation. The traction force on the artificial leather gradually increases and then decreases rapidly to further enhance the traction quality and effectively avoid the phenomenon of the artificial leather breaking due to excessive force, thus strengthening the protection effect.

[0040] A ball 431 is fixed to the upper end of the nut;

[0041] A push-pull rod 323 is fixed on one side of the rear insertion block 321. The right end of the push-pull rod 323 is spherical. After the ball 431 moves to the limit distance outward, the disc 41 rotates again, and the ball 431 contacts the spherical part of the push-pull rod 323. The right end of the slide rod 322 is connected to the right side of the inner wall of the through hole by a spring.

[0042] The left side of the connecting rod 32 is provided with a slot, and the insertion block 321 is inserted into the slot after it is moved;

[0043] Motor 4 rotates alternately in clockwise and counterclockwise directions, and the rotation angle is fixed at 180 degrees. After motor 4 rotates 90 degrees and ball 431 moves to the limit distance outward, push rod 323 aligns with ball 431, and at the same time, protrusion 34 is located at the edge of the inclined part of connecting rod 32.

[0044] Example 4: Figure 10As shown in Embodiment 2, when the movement range of the U-shaped block 331 is adjusted to the maximum, the nut moves to the extreme position outward, thereby driving the ball 431 to move to the extreme position outward. At this time, the distance that the traction shaft 2 moves to the left increases, and the traction strength is greater. At the same time, after the ball 431 rotates to ninety degrees, it contacts the right end of the push-pull rod 323 and pushes the push-pull rod 323 to move the insertion block 321 to the left and insert it into the slot. At this time, the height difference between the bottom end of the inclined part of the connecting rod 32 and the left end of the insertion block 321 changes, and the height difference decreases. In Embodiment 3, the strength when the traction shaft 2 is raised and then lowered is smaller, so as to maintain a high traction force and fully avoid the artificial leather from loosening and affecting the subsequent winding quality. In addition, since the strength of the traction shaft 2 is reduced when it is lowered, the impact force can be reduced, the service life of the structure can be improved, and the rapid and large-scale loosening of the artificial leather can be avoided, thus fully improving the traction quality.

[0045] As the connecting rod 32 is reset, the protrusion 34 and the inclined portion of the insertion block 321 move in opposite directions, causing the protrusion 34 to move to the left on the inclined portion of the insertion block 321. The height of the traction shaft 2 gradually decreases, so as to slowly loosen the artificial leather. This ensures the traction strength while avoiding continuous high-intensity traction that could damage the artificial leather, thus enhancing its protective performance.

[0046] The preparation process includes the following steps:

[0047] Step S1: The TPEE material is fed into a three-way dehumidification and vacuum drying unit and continuously dried. Then, it is fed into the three hoppers A, B, and C based on two-stage hot air drying in real time and in a quantitative manner.

[0048] Step S2: The material is fed into the electrically heated screw, and three layers are co-extruded corresponding to the screw: a bottom layer of thermally composite high-polarity modified TPEE, a conventional middle layer of TPEE, and a top layer of modified colored TPEE, thereby extruding and molding.

[0049] Step S3: The extruded material enters the mold and the rubber roller step surface. The chilled water unit adopts a one-to-three configuration to introduce cooling water into the stripping roller section, the patterned roller section and the rubber roller. At the same time, polyester fabric is introduced into the patterned roller section and the rubber roller. The fabric and film are thermally bonded on the rubber roller surface, thus realizing the glue-free bonding and thermal bonding process. This saves one glue bonding process, and the fabric can be recycled, which is more energy-saving and environmentally friendly.

[0050] Step S4: The fabric-plastic patterned artificial leather was directly heat-coated using the heat energy of the film above 200°C;

[0051] Step S5: Then, the artificial leather is pulled by the traction roller section, and the edge material is cut off by the edge cutting device station. The edge material is then crushed and sent to the B hopper for reuse through the fan and pipeline.

[0052] Step S6: Then the artificial leather is introduced into the flattening expansion roller to flatten it, and then guided into the automatic dual-station take-up air shaft through the constant tension frame.

[0053] Step S7: Automatic winding, online packaging, shelf placement, warehousing, and preparation for shipment.

The chilled water unit adopts a one-to-three form to introduce cooling water into the peeling roller section, the patterned roller section and the rubber roller. At the same time, polyester fabric is introduced into the patterned roller section and the rubber roller. The fabric and film on the rubber roller surface are thermally bonded. Step S4: The fabric-plastic patterned artificial leather was directly heat-coated using the heat energy of the film above 200°C; Step S5: Then, the artificial leather is pulled by the traction roller section, and the edge material is cut off by the edge cutting device station. The edge material is then crushed and sent to the B hopper for reuse through the fan and pipeline. Step S6: Then the artificial leather is introduced into the flattening expansion roller to flatten it, and then guided into the automatic dual-station take-up air shaft through the constant tension frame. Step S7: Automatic winding, online packaging, shelf placement, warehousing, and preparation for shipment.
