Description

Technical Field

[0001] The utility model relates to a processing device, more specifically, it relates to an artificial leather impregnation processing device. Background Art

[0002] Artificial leather is a plastic product that looks and feels like artificial leather and can be used instead of it. It is usually made of fabric as the base, coated with synthetic resin and various plastic additives. The wet processing technology can be carried out by dipping. The dipping method is to let the fabric pass through the ironing roller to heat and remove moisture, and then dip it in the polyurethane compound slurry. After the slurry is coated and solidified, the excess slurry is removed, and then most of the DMF aqueous solution is separated and then washed and dried. In the prior art, since multiple devices are used to perform a single step respectively, artificial leather can be produced in an assembly line, but the number of devices required in this assembly line production is large, so the volume is bloated and it is not suitable for small studios that need to customize the fabric. Therefore, an artificial leather dipping processing equipment is needed, which can implement multiple wet processing steps.

[0003] In view of the above reasons, how to use one device to implement multiple wet processing steps is exactly the problem considered in this application. Utility Model Content

[0004] In view of the shortcomings of the prior art, an artificial leather impregnation processing device is provided, which can implement multiple wet processing steps.

[0005] To achieve the above-mentioned purpose, the following technical solution is provided: an artificial leather impregnation processing device, comprising a bracket, the bracket is fixedly connected to an impregnation tank, the bottom of the impregnation tank is fixedly connected to a motor, the motor comprises a transmission shaft extending into the interior of the impregnation tank, the transmission shaft is fixedly connected to a protection seat and a receiving plate rotatably connected to the protection seat, the receiving plate is connected to a plurality of fixed rods, the fixed rods are connected to a patterned grid, and the impregnation tank is also fixedly connected to a first valve port arranged at the top of the impregnation tank and a second valve port arranged at the bottom of the impregnation tank.

[0006] In summary, the above technical solution has the following beneficial effects: in the impregnation wet processing process, the pre-treated fabric is first impregnated in the polyurethane compound slurry, a receiving tray is provided for placing the pre-treated fabric, and then the polyurethane compound slurry is poured into the impregnation tank, and then the motor is started to rotate the receiving tray, and the fabric will fit with the pattern grid under the action of centrifugal force, so that the motor rotation speed can be adjusted by changing the pattern grid to form different bright types, smoothness, etc., which is suitable for small studios that need to customize fabric processing;

[0007] After the slurry is initially coated and solidified, a film is formed on the surface of the fabric. At this time, the excess slurry can be guided to flow out through the second valve port, and the excess slurry attached to the artificial leather can also be separated by centrifugal force, which can avoid the damage to the film caused by common high-pressure flushing or brush scraping. After the slurry is separated, a certain amount of DMF aqueous solution still remains. Therefore, it is necessary to fill the immersion tank with water first, and start the motor to accelerate the exchange of DMF aqueous solution with external water, so as to reduce the DMF concentration, and then discharge the waste water, which can effectively reduce the DMF content and remove the excess slurry in the immersion tank at the same time. After repeating the above process many times, the DMF content is greatly reduced. At this time, the motor speed is increased for final processing, and the DMF aqueous solution remaining in the film can be thrown out by centrifugal force for preliminary drying;

[0008] After the initial drying, the blower can be connected to the first valve port or the second valve port, and the motor speed can be slowed down for uniform air drying. In this way, the artificial leather can be separated from the pattern grid by wind power, which can avoid damage to the film to the greatest extent.

[0009] The main reason for using multiple devices to perform a single step in the prior art is the need to mass-produce artificial leather. Each device only needs to repeatedly perform a fixed function. If it is set on an assembly line, a large amount of artificial leather can be quickly processed. However, small studios do not have such a demand. Small studios usually customize artificial leather patterns according to customer needs, so they cannot directly purchase finished artificial leather for production. In addition, the working space of a small studio is small, which is not suitable for placing too many devices like an assembly line. Therefore, a device that can implement multiple wet processing steps is needed to increase space utilization.

[0010] The utility model is provided with a pattern grid and a motor, and utilizes the centrifugal force generated by the rotation of the motor to drive the artificial leather to be attached to the pattern grid, and then coordinately implements a plurality of wet processing steps by adjusting the motor speed.

[0021] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. The same parts are represented by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "bottom surface" and "top surface", "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0022] Reference Figure 1-4 As shown, an artificial leather impregnation processing device includes a bracket 1, the bracket 1 is fixedly connected to an impregnation tank 2, a motor 3 is fixedly connected to the bottom of the impregnation tank 2, the motor 3 includes a transmission shaft 31 extending into the impregnation tank 2, the transmission shaft 31 is fixedly connected to a protection seat 32 and a receiving plate 4 rotatably connected to the protection seat 32, the receiving plate 4 is connected to a plurality of fixed rods 41, the fixed rods 41 are connected to a pattern grid 42, and the impregnation tank 2 is also fixedly connected to a first valve port 21 arranged at the top of the impregnation tank 2 and a second valve port 22 arranged at the bottom of the impregnation tank 2;

[0023] In the impregnation wet processing technology, the pre-treated fabric is first impregnated with the polyurethane compound slurry, and a receiving tray 4 is set to place the pre-treated fabric, and then the polyurethane compound slurry is poured into the impregnation tank 2, and then the motor 3 is started to rotate the receiving tray 4, and the fabric will fit with the pattern grid 42 under the action of centrifugal force. In this way, the rotation speed of the motor 3 can be adjusted by replacing the pattern grid 42 to form different bright shapes, smoothness, etc., which is suitable for small studios that need to customize fabric processing;

[0024] After the slurry is initially coated and solidified, a film is formed on the surface of the fabric. At this time, the excess slurry can be guided to flow out through the second valve port 22, and the excess slurry attached to the artificial leather can also be separated by centrifugal force, so that the damage to the film caused by common high-pressure flushing or brush scraping can be avoided. After the slurry is separated, a certain amount of DMF aqueous solution still remains. Therefore, it is necessary to fill the immersion tank 2 with water first, and start the motor 3 to accelerate the exchange of the DMF aqueous solution with external water, so as to reduce the DMF concentration, and then discharge the waste water, which can effectively reduce the DMF content and remove the excess slurry in the immersion tank 2 at the same time. After repeating the above process for many times, the DMF content is greatly reduced. At this time, the speed of the motor 3 is increased for final processing, and the DMF aqueous solution remaining in the film can be thrown out by centrifugal force for preliminary drying;

[0025] After the initial drying, the blower can be connected to the first valve port 21 or the second valve port 22, and the speed of the motor 3 can be slowed down for uniform air drying, so that the artificial leather and the pattern grid 42 can be separated by wind power, which can avoid damage to the film to the greatest extent;

[0026] The main reason for using multiple devices to perform a single step in the prior art is the need to mass-produce artificial leather. Each device only needs to repeatedly perform a fixed function. If it is set on an assembly line, a large amount of artificial leather can be quickly processed. However, small studios do not have such a demand. Small studios usually customize artificial leather patterns according to customer needs, so they cannot directly purchase finished artificial leather for production. In addition, the working space of a small studio is small, which is not suitable for placing too many devices like an assembly line. Therefore, a device that can implement multiple wet processing steps is needed to increase space utilization.

[0027] The utility model is provided with a pattern grid 42 and a motor 3, and utilizes the centrifugal force generated by the rotation of the motor 3 to drive the artificial leather to be attached to the pattern grid 42, and then adjusts the rotation speed of the motor 3 to coordinate and implement multiple wet processing steps.

[0028] Furthermore, one end of the fixing rod 41 facing the receiving plate 4 and away from the rotation center of the receiving plate 4 is chamfered, and the receiving plate 4 is provided with a plurality of sockets 43 for inserting the fixing rod 41;

[0029] Since the receiving plate 4 will also exert centrifugal force on the fixing rod 41 when rotating, so that the lower part of the fixing rod 41 away from the rotation center of the receiving plate 4 is squeezed against the receiving plate 4, it is necessary to set a chamfer at this location, so that the pressure caused by the centrifugal force can be redistributed to the internal structure, reducing material deformation and avoiding cracks as much as possible, and it can also facilitate assembly.

[0030] Furthermore, the fixing rod 41 is provided with a slot 411 for placing the pattern grid 42, the slot 411 is arranged in a direction away from the receiving plate 4, and the slot bottom of the slot 411 is arranged parallel to the surface of the receiving plate 4 away from the motor 3;

[0031] The fixing rod 41 is used to position the pattern grid 42. Therefore, in order to reduce the impact on the membrane pattern, the bottom of the slot 411 needs to be set parallel to the surface of the receiving plate 4 away from the motor 3 to prevent the membrane pattern from being deformed due to the angle formed between the bottom of the slot 411 and the upper surface of the receiving plate 4.

[0032] Furthermore, the fixing rod 41 is also abutted against a positioning ring 412 for closing the slot 411, and the positioning ring 412 is fixedly connected to a fixing ring 413 for inserting into the slot 411;

[0033] In order to prevent the pattern grid 42 from being thrown out and to further fix the position of the pattern grid 42, a positioning ring 412 is provided to close the slot 411, and at the same time, the fixing ring 413 is inserted into the slot 411 from top to bottom, and the moving direction is perpendicular to the direction of the centrifugal force, so the positioning ring 412 will not be separated from the fixing rod 41 due to the centrifugal force.

[0034] Furthermore, the first valve port 21 is disposed transversely and the lowest level of the first valve port 21 is higher than the highest level of the fixing rod 41, and the second valve port 22 is disposed transversely and the lowest level of the second valve port 22 is higher than the surface of the receiving plate 4 away from the motor 3.

[0035] During the coating stage, since the slurry contains bubbles, the slurry with a higher bubble content will be at the top, so the first valve port 21 is set horizontally and the lowest horizontal point of the first valve port 21 is higher than the highest point of the fixed rod 41, so that the slurry with a higher bubble content can be discharged from the first valve port 21 while ensuring that the artificial leather is always immersed in the slurry. At this time, new slurry continuously enters the impregnation tank 2 from the second valve port 22. In addition, the second valve port 22 is set horizontally and the lowest horizontal point of the second valve port 22 is higher than the surface of the receiving plate 4 away from the motor 3. This can ensure that the slurry at the artificial leather will not be deposited when the slurry flows, thereby accelerating the speed of updating the slurry.

[0036] Furthermore, a drain valve 23 is fixedly connected to the bottom of the immersion tank 2, and a closing plate 24 for closing the drain valve 23 is slidably connected to the drain valve 23;

[0037] The closing plate 24 is fixedly connected with a connecting strip 241 which is slidably connected with the dipping tank 2, the connecting strip 241 is fixedly connected with a rack 242, the transmission shaft 31 is also fixedly connected with a gear 33 which is meshed with the rack 242, and the length of the connecting strip 241 is the shortest distance from the axis of the transmission shaft 31 to the drain valve 23;

[0038] Since the first valve port 21 and the second valve port 22 have other uses, it is necessary to set up a separate valve port for discharging waste liquid. Therefore, a drain valve 23 is set. The drain valve 23 is usually closed by the closing plate 24, and the closing plate 24 is driven to move by the motor 3. The transmission shaft 31 can first drive the rack 242 to move through the gear 33, and after the rack 242 is separated from the gear 33, the connecting strip 241 will not contact the gear 33, so the closing plate 24 will stop moving. In order to ensure the formation of the film of artificial leather in the wet processing technology, the transmission shaft 31 will only rotate in one direction. Therefore, when the closing plate 24 closes the drain valve 23, even if the rack 242 is separated from the gear 33, the rack 242 cannot move in the opposite direction, thereby playing the role of a safety structure.

[0039] Furthermore, the dipping tank 2 may be detachably connected with a cover plate 5 .

[0040] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
