Description

TECHNICAL FIELD

[0001] The embodiment of the present application relates to the technical field of roll coaters, in particular to a release paper roll coater. BACKGROUND

[0002] In the production process of artificial leather using release paper, the paste-like resin and other raw materials of artificial leather are coated on the surface of the release paper, and then the artificial leather is obtained by peeling off the release paper after drying, cross-linking, curing and other processes.

[0003] Traditional release paper coating devices often have many limitations. In terms of release paper processing, due to the thin thickness of the release paper, wrinkles are easily generated, and the traditional equipment lacks effective flattening measures, which leads to uneven coating during the coating process, seriously affecting the quality stability and consistency of the product. In terms of the setting of the coating roller, most traditional devices are only equipped with a single coating roller, which cannot flexibly meet the diversified needs of customers for coating, limiting the application range and production flexibility of the device. Based on the above reasons, the present application proposes a release paper roll coater. CONTENT OF THE INVENTION

[0004] In view of the above problems, the embodiment of the present application provides a release paper roll coater to solve the problem of uncontrollable and uneven coating.

[0005] The embodiment of the present application provides a release paper roll coater, which comprises:

[0006] A flattening roller is arranged on the upper side of the flattening roller and is used to flatten the release paper;

[0007] A front guide roller and a rear guide roller are arranged, the upper part of the two ends of the front guide roller is fixed on the wallboard through a screw rod, the rear guide roller has a fixed stroke, and the release paper is flattened by the flattening roller and then passes through the front guide roller and the rear guide roller in sequence to be tightly attached to the coating roller and form a certain wrap angle;

[0008] A coating system comprises a first coating roller, a second coating roller and a third coating roller, the specifications of which can be selected according to the coating amount of the customer, a same manual rotary roller arm is installed on the first coating roller, the second coating roller and the third coating roller, and any one of the coating rollers can be selected after the manual rotary roller arm is lifted by a first air cylinder;

[0009] A knife holder part comprises a polyurethane blade tightly attached to the coating roller, a feeding pipe is used to place the material in the area between the blade and the coating roller, the bottom of the blade is placed on the knife holder, the upper part is pressed by a pressing plate, the feeding pipe is fixed on a rodless air cylinder and uniformly controlled by a PLC, the knife holder is fixed on a knife holder fixing seat, and the knife holder fixing seat is connected to a fourth air cylinder through a knife holder saddle to realize forward and backward movement;

[0010] A control box is used to control and operate each part of the device.

[0011] The chemical recycling system includes a receiving tank, a long slurry tank, and a water tank. The chemical overflowing between the coating roller and the blade holder is collected in the receiving tank and flows into the long slurry tank, and then into the water tank at the bottom for collection and reuse. The receiving tank is located on a receiving tank fixing seat, which is fixed to the left and right wall panels.

[0012] In some embodiments, the front guide roller and the rear guide roller are fixed in the form of a second cylinder and a third cylinder. When the roller coating process is not required, the second cylinder and the third cylinder retract, and the front guide roller and the rear guide roller descend, so that the release paper passes directly through the first guide roller after passing through the flattening roller without passing through the coating roller.

[0013] In some embodiments, the release paper used in the leather industry is typically less than 10 μm thick, and the flattening roller is used to prevent wrinkles in the release paper to achieve a more uniform coating.

[0014] In some embodiments, the grout receiving tank can be removed from the grout receiving tank mounting base at any time for cleaning.

[0015] Through the above scheme, the release paper first enters the flattening roller. The flattening roller, using its own structure and rotational motion, flattens the release paper, ensuring it enters the subsequent processes in a flat state. When different coating rollers are needed, the first cylinder rises, and the operator manually rotates the roller-changing arm to switch between the first, second, or third coating rollers. During the coating process, the chemical is placed between the polyurethane blade and the first coating roller through the feed pipe. As the coating roller rotates, it picks up the chemical, and the polyurethane blade applies the coating. Excess chemical material on the outer surface of the roller is scraped off, leaving only the chemical material in the groove of the coating roller. The coating roller then applies the chemical material to the release paper. The feeding pipe is fixed to the rodless cylinder. The PLC controls the movement of the rodless cylinder according to the preset program, thereby achieving uniform feeding. In terms of chemical material recovery, the chemical material overflowing between the coating roller and the knife holder flows out from both sides and is collected by the slurry receiving tank. The chemical material collected in the slurry receiving tank flows into the long slurry tank. Due to the certain slope of the long slurry tank, the chemical material flows into the water tank for collection and reuse under the action of gravity. All components of the entire device are controlled and operated by the control box.

[0030] To facilitate understanding of the technical solutions in the embodiments of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0031] like Figures 1-5 As shown in the embodiment of this application, a release paper roller coating machine is provided, including:

[0032] The flattening roller 4 has a release paper 3 on its upper side and is used to flatten the release paper 3. When the release paper 3 is used in the leather industry, its thickness is generally less than 10μm. The flattening roller 4 is used to prevent the release paper 3 from wrinkling so as to achieve a more uniform coating.

[0033] The front guide roller 5 and the rear guide roller 13 are fixed to the wall plate at both ends by screws 6. The rear guide roller 13 has a fixed stroke. After the release paper 3 is flattened by the flattening roller 4, it passes through the front guide roller 5 and the rear guide roller 13 in sequence and sticks tightly to the coating roller and forms a certain wrapping angle.

[0034] Furthermore, the front guide roller 5 and the rear guide roller 13 are fixed in the form of the second cylinder 1 and the third cylinder 15. When the roller coating process is not required, the second cylinder 1 and the third cylinder 15 retract, and the front guide roller 5 and the rear guide roller 13 descend, so that the release paper 3 passes directly through the first guide roller 14 after passing through the flattening roller 4 without passing through the coating roller.

[0035] The coating system includes a first coating roller 8, a second coating roller 9 and a third coating roller 11. The specifications can be selected according to the customer's coating amount. The first coating roller 8, the second coating roller 9 and the third coating roller 11 are equipped with the same manual rotary roller changing arm 10. The manual rotary roller changing arm 10 can select any one of the coating rollers after being raised by the first cylinder 2.

[0036] The blade holder section 12 includes a polyurethane blade 210 that is in close contact with the coating roller, a feeding tube 29 for placing the chemical material in the area between the blade 210 and the coating roller, the bottom of the blade 210 is placed on the blade holder 213 and the top is pressed by the pressure plate 211, the feeding tube is fixed on the rodless cylinder 27 and the feeding is controlled by the PLC to be uniform, the blade holder 213 is fixed on the blade holder fixing seat 22, and the blade holder fixing seat 22 is connected to the fourth cylinder 26 through the blade holder saddle 24 to realize forward and backward movement;

[0037] Control box 7 is used to control and operate various components of the equipment;

[0038] The chemical recovery system includes a receiving tank 32, a long slurry tank 35, and a water tank 36. The chemical overflowing between the coating roller and the blade holder 213 is collected in the receiving tank 32 and flows into the long slurry tank 35, and then into the water tank 36 at the bottom for collection and reuse. The receiving tank 32 is located on a receiving tank 32 fixing seat, which is fixed to the left wall panel 31 and the right wall panel 34. The receiving tank 32 can be removed from the receiving tank fixing seat 33 at any time for cleaning.

[0039] Working principle: Release paper 3 first enters flattening roller 4. Flattening roller 4 uses its own structure and rotational motion to flatten the release paper 3, which may have wrinkles, ensuring that the release paper 3 enters the subsequent process in a flat state. After flattening, the release paper 3 passes through front guide roller 5 and rear guide roller 13 in sequence. The stroke of front guide roller 5 can be adjusted by screw 6, and it cooperates with the fixed stroke of rear guide roller 13 to make the release paper 3 tightly adhere to the first coating roller 8 and form a suitable wrap angle. When it is necessary to select coating rollers with different coating amounts, the first cylinder 2 rises, and the operator manually rotates the roller changing arm 10 to switch any one of the first coating roller 8, second coating roller 9, or third coating roller 11. During the coating process, the chemical is placed between polyurethane blade 210 and first coating roller 8 through the discharge pipe 29. When the coating roller rotates, it picks up the chemical, and polyurethane blade 210 scrapes off the excess chemical on the outer surface of the coating roller, leaving only the coating roller concave. The chemical material in the cavity is then coated onto the release paper 3 by the coating roller. The feeding pipe is fixed to the rodless cylinder 27. The PLC controls the movement of the rodless cylinder 27 according to the preset program to achieve uniform feeding. The blade holder 12 is connected to the fourth cylinder 26 through the blade holder fixing seat 22 and the blade holder saddle 24. When the blade holder 213 is needed for coating, the fourth cylinder 26 pushes the blade holder 213 forward so that the blade 210 is in close contact with the coating roller. When it is not needed, the fourth cylinder 26 pulls the blade holder 213 back to a safe area to avoid damage to the blade 210. In terms of chemical material recovery, the chemical material overflowing between the coating roller and the blade holder 213 flows out from both sides and is collected by the slurry receiving tank 32. The chemical material collected in the slurry receiving tank flows into the long slurry tank 35. Since the long slurry tank 35 has a certain slope, the chemical material flows into the water tank 36 for collection and reuse under the action of gravity. All components of the entire device are controlled and operated by the control box 7.
