Description

Technical Field

[0001] This utility model relates to the field of leather production technology, and in particular to a water-squeezing machine for the production of water-based polyurethane synthetic leather. Background Technology

[0002] Waterborne polyurethane synthetic leather is a synthetic leather material characterized by the use of water as a solvent instead of conventional organic solvents. It is a coating system composed of polyurethane resin, fillers, and additives, which is applied to the surface of textiles or other substrates.

[0003] Patent application number 202121631960.X discloses a dewatering machine for producing waterborne polyurethane synthetic leather, comprising two support frames, a motor mounted at one end of one of the support frames, a drive roller mounted between the two support frames, one end of the drive roller being fixedly connected to the output shaft of the motor, a driven roller mounted between the two support frames, the driven roller being positioned above the drive roller, feeding rollers mounted at the ends of the two support frames, and a collection structure provided between the two support frames, the collection structure comprising a collection box and sliding rods, the number of which is specified. There are two sliding rods, each fixedly connected to opposite sides of two support frames and positioned below the drive roller. In use, the motor is started, driving the drive roller to rotate. The leather is placed between the drive roller and the driven roller, which work together to apply pressure to the leather, squeezing out the water. The squeezed-out water falls into the collection box due to gravity. Since the inner wall of the collection box is inclined, the water in the collection box flows from the outlet into the water outlet pipe. The water outlet pipe is inserted into the water collection device, so that the squeezed-out water is recycled, avoiding waste of water resources.

[0004] In current technology, although water can be recycled by setting up a collection box to avoid water waste, the leather needs to be placed between the active roller and the driven roller before squeezing out the water. However, the distance between the active roller and the driven roller is small and the spacing cannot be adjusted, which makes it difficult to place the leather and results in poor applicability. Utility Model Content

[0005] Therefore, the technical problem to be solved by this utility model is to overcome the problem that the distance between the active roller and the driven roller cannot be adjusted in the prior art, making it difficult to place leather.

[0006] To solve the above-mentioned technical problems, this utility model provides a dewatering machine for the production of water-based polyurethane synthetic leather.

[0007] In one embodiment of this utility model, a water collection tank is included, and symmetrically arranged L-shaped connecting plates are fixedly connected inside the water collection tank. An adjusting plate is inserted above the L-shaped connecting plates. A motor is fixedly connected to the side of one L-shaped connecting plate away from the other L-shaped connecting plate. A rotating shaft is fixedly connected to the output end of the motor. A rotating rod is slidably connected above the rotating shaft. A bevel gear is fixedly connected to the bottom of the rotating shaft and the top of the rotating rod, respectively. A second bevel gear meshes with the outer side of the first bevel gear. A squeezing roller is fixedly connected to the side of the second bevel gear away from the first bevel gear, and the two squeezing rollers are rotatably connected to the L-shaped connecting plates and the adjusting plate, respectively. An adjusting component is provided on the adjusting plate corresponding to the position of the motor, and the adjusting component includes a planar gear and a rack, which mesh.

[0008] In one embodiment of this utility model, the adjustment component includes a second motor, which is located on the adjustment plate near the first motor; the output end of the second motor is fixedly connected to a second rotating shaft; a planar gear is fixedly connected to the end of the second rotating shaft away from the second motor; a rack meshes with the outer side of the planar gear; and the rack is fixedly connected to one side of the adjustment plate.

[0009] In one embodiment of this utility model, the L-shaped connecting plate is fixedly connected to the mounting plate at the positions of motor 1 and motor 2, and motor 1 and motor 2 are respectively fixedly connected to the mounting plate.

[0010] In one embodiment of this utility model, a cross rod is fixedly connected to the lower part of the rotating rod; a cross groove is provided above the first rotating shaft, and the cross rod is slidably connected in the cross groove.

[0011] In one embodiment of the present invention, an insert plate is fixedly connected to the lower part of the adjusting plate; a slot is provided on the upper part of the L-shaped connecting plate, and the insert plate is inserted into the slot.

[0012] In one embodiment of this utility model, a fixing plate is fixedly connected above the adjusting plate at the position corresponding to the No. 1 bevel gear; a positioning ring is rotatably connected to the fixing plate at the position corresponding to the No. 1 bevel gear, and the positioning ring is fixedly connected below the No. 1 bevel gear.

[0015] The above-mentioned technical solution of this utility model has the following advantages compared with the prior art:

[0016] The water-squeezing machine for producing water-based polyurethane synthetic leather described in this utility model first starts a second motor by the operator before performing the water-squeezing operation on the synthetic leather. The second motor drives the second rotating shaft to rotate, which in turn drives the planar gear to rotate. The rotation of the planar gear drives the rack to move upward, which in turn causes the adjusting plate and the upper water-squeezing roller to rise. This increases the distance between the two water-squeezing rollers, making it easier to place the synthetic leather and improving its applicability. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0026] Reference Figures 1-6As shown, this utility model discloses a water-based polyurethane synthetic leather production dewatering machine, comprising a water collection tank 1, with symmetrically arranged L-shaped connecting plates 2 fixedly connected inside the water collection tank 1; an adjusting plate 3 is inserted above the L-shaped connecting plates 2; a motor 21 is fixedly connected to the side of one L-shaped connecting plate 2 away from the other L-shaped connecting plate 2; a rotating shaft 22 is fixedly connected to the output end of the motor 21; a rotating rod 23 is slidably connected above the rotating shaft 22; and a bevel gear 26 is fixedly connected to the bottom of the rotating shaft 22 and the top of the rotating rod 23, respectively. The first bevel gear 26 is meshed with a second bevel gear 27 on its outer side; a squeezing roller 28 is fixedly connected to the side of the second bevel gear 27 away from the first bevel gear 26, and the two squeezing rollers 28 are respectively rotatably connected to the L-shaped connecting plate 2 and the adjusting plate 3; the adjusting plate 3 is provided with an adjusting component corresponding to the position of the first motor 21, and the adjusting component includes a planar gear 33 and a rack 34, which mesh; in the current technology, although water can be recycled by setting up a collection box to avoid water waste, it is necessary to... The leather needs to be placed between the driving roller and the driven roller. However, the distance between the driving roller and the driven roller is small and the spacing cannot be adjusted, making it difficult to place the leather and resulting in poor applicability. Before squeezing the synthetic leather, the planar gear 33 rotates to drive the rack 34 upward. The upward movement of the rack 34 causes the adjusting plate 3 and the upper squeezing roller 28 to rise, which increases the distance between the two squeezing rollers 28, making it easier to place the synthetic leather and improving applicability. After the synthetic leather is placed, the planar gear 33 is reversed to drive the adjusting plate 3 and the upper squeezing roller 28 upward. As the section plate 3 and the upper squeezing roller 28 descend, the distance between the two squeezing rollers 28 is reduced. After the synthetic leather is placed, the staff starts the first motor 21, which drives the first rotating shaft 22 to rotate. The rotation of the first rotating shaft 22 drives the rotating rod 23 to rotate. The first rotating shaft 22 and the rotating rod 23 respectively drive the first bevel gear 26 to rotate. The rotation of the first bevel gear 26 drives the second bevel gear 27 to rotate. The two second bevel gears 27 rotate in opposite directions, driving the two squeezing rollers 28 to rotate in opposite directions, thus squeezing water from the synthetic leather.

[0027] In one embodiment of this utility model, the adjustment assembly includes a second motor 31, which is located on the adjustment plate 3 near the first motor 21. A second rotating shaft 32 is fixedly connected to the output end of the second motor 31. A planar gear 33 is fixedly connected to the end of the second rotating shaft 32 away from the second motor 31. A rack 34 meshes with the outer side of the planar gear 33. The rack 34 is fixedly connected to one side of the adjustment plate 3. When synthetic leather needs to be placed between the two squeezing rollers 28, the second motor 31 is started by the operator, and the second motor 31 drives... The second rotating shaft 32 rotates, which drives the planar gear 33 to rotate. The planar gear 33 rotates, which drives the rack 34 to move upward. The upward movement of the rack 34 causes the adjusting plate 3 and the upper squeezing roller 28 to rise, which can increase the distance between the two squeezing rollers 28, thereby facilitating the placement of synthetic leather and improving its applicability. After the synthetic leather is placed, the second motor 31 is restarted to reverse the planar gear 33, which drives the adjusting plate 3 and the upper squeezing roller 28 to descend, which can reduce the distance between the two squeezing rollers 28, thereby enabling the squeezing operation.

[0029] In one embodiment of this utility model, a cross rod 24 is fixedly connected to the lower part of the rotating rod 23; a cross groove 25 is opened above the first rotating shaft 22, and the cross rod 24 is slidably connected in the cross groove 25; through the cross rod 24 fixedly connected to the lower part of the rotating rod 23 and the cross groove 25 opened above the first rotating shaft 22, the cross rod 24 will rise or fall together when the adjusting plate 3 rises or falls, so that the first bevel gear 26 corresponds to the second bevel gear 27.

[0030] In one embodiment of this utility model, an insert plate 35 is fixedly connected to the lower part of the adjusting plate 3; a slot 36 is provided above the L-shaped connecting plate 2, and the insert plate 35 is inserted into the slot 36; by means of the insert plate 35 fixedly connected to the lower part of the adjusting plate 3 and the slot 36 provided above the L-shaped connecting plate 2, the insert plate 35 is inserted into the slot 36, and when the adjusting plate 3 rises or falls, the cooperation between the insert plate 35 and the slot 36 can stabilize the adjusting plate 3.

[0031] In one embodiment of this utility model, a fixing plate 4 is fixedly connected above the adjusting plate 3 at the position corresponding to the first bevel gear 26; a positioning ring 41 is rotatably connected to the fixing plate 4 at the position corresponding to the first bevel gear 26, and the positioning ring 41 is fixedly connected below the first bevel gear 26; through the fixing plate 4 fixed on the adjusting plate 3 and the positioning ring 41 fixed on the first bevel gear 26, when the adjusting plate 3 rises or falls, the fixing plate 4 and the fixing ring cooperate to drive the cross rod 24 to rise or fall together, so that the first bevel gear 26 and the second bevel gear 27 can correspond.

[0032] In one embodiment of this utility model, a filter plate 5 is inserted below the L-shaped connecting plate 2 corresponding to the water tank 1; when water falls into the water tank 1 through the filter plate 5 inserted below the water tank 1, the filter plate 5 will filter out the impurities contained in the water.

[0034] Working principle:

[0035] In current technologies, although water can be recycled by setting up collection boxes to avoid water waste, the leather needs to be placed between the active and driven rollers before squeezing it out. However, the distance between the active and driven rollers is small and the spacing cannot be adjusted, making it difficult to place the leather and resulting in poor applicability. Before squeezing synthetic leather, the operator starts the second motor 31, which drives the second rotating shaft 32 to rotate. The rotation of the second rotating shaft 32 drives the planar gear 33 to rotate, which in turn drives the rack 34 to move upward. The upward movement of the rack 34 causes the adjusting plate 3 and the upper squeezing roller 28 to rise, which increases the distance between the two squeezing rollers 28, making it easier to place the synthetic leather and improving applicability. After the synthetic leather is placed, the second motor 31 is started again, causing the planar gear 33 to reverse and drive the adjusting plate 3 and the upper squeezing roller 28 to descend, which reduces the distance between the two squeezing rollers 28, allowing the squeezing process to begin.

[0036] After the synthetic leather is placed, the staff starts motor 21. Motor 21 drives rotating shaft 22 to rotate, rotating shaft 22 drives rotating rod 23 to rotate, rotating shaft 22 and rotating rod 23 drive bevel gear 26 to rotate, bevel gear 26 drives bevel gear 27 to rotate, and the two bevel gears 27 rotate in opposite directions, driving two squeezing rollers 28 to rotate in opposite directions, thus squeezing water from the synthetic leather.

[0037] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
