Problems solved by technology

But this invention also has the following defects: 1. The plastic-absorbing oil in the liquid tank is continuously supplied to the upper auxiliary roller, and the oil in the liquid tank is continuously reduced, so it is necessary to continuously replenish the oil in the liquid tank, which is very troublesome
2. The oil on the upper pressing roller and the upper auxiliary roller is easy to drip on the plastic plate, making the oil on the surface of the plastic plate uneven
3. The plastic-absorbing oil is relatively viscous, and it is prone to stratification after standing for a period of time. The large amount of plastic-absorbing oil in the liquid tank is basically in a static state, and it is prone to stratification, which affects the quality of the plastic-absorbing oil and brushing.

Embodiment 1

[0025] Such as figure 1 , figure 2 As shown, the coating device for plastic boards includes a frame, a liquid tank 1 and a motor. The frame is provided with a lower coating roller 3 and a height-adjustable upper coating roller 5, and the lower part of the lower coating roller 3 is located in the liquid tank. Inside Pool 1. The motor is used to drive the lower coating roller 3 and the upper coating roller 5, and when the motor is started, the lower coating roller 3 and the upper coating roller 5 can rotate. The lower auxiliary roller 4 and the upper auxiliary roller 6 arranged as a truncated cone are installed on the frame, and the taper of the upper auxiliary roller 6 is 15-30 degrees, which is set to 20 degrees in this embodiment; Used in conjunction, and the lower auxiliary roller 4 cooperates with the lower coating roller 3. The frame is also provided with a liquid storage tank 7, which is used to supply plastic-absorbing oil for the upper auxiliary roller 6. The botto...

Embodiment 2

[0028] The difference between embodiment 2 and embodiment 1 is that the coating device for plastic plates is provided with oil discharge pipe 13 instead of oil outlet pipe 11 and flow automatic regulating valve 12, and one end of oil discharge pipe 13 communicates with the upper part of liquid storage tank 7, The other end is located above the liquid storage pool 1, such as Figure 4 shown. By arranging the oil discharge pipe 13, the oil quantity in the liquid storage tank 7 can be kept in dynamic balance, so as to avoid overflowing of plastic-absorbing oil.

Abstract

The invention belongs to a device for jetting or pouring liquid or other fluids onto the surface of a workpiece or making the liquid or other fluids flow on the surface of the workpiece and particularly discloses a coating device for a plastic plate. The coating device comprises a rack and a liquid storage pool, and he rack is provided with a lower coating roller and an upper coating roller; the rack is provided with a liquid storage box; the lower coating roller is provided with a rotating shaft, the end of the rotating shaft is fixedly provided with a rotating rod, and a push rod is hinged to the rotating rod; the liquid storage pool is internally provided with a spring and an oil supply unit, and the oil supply unit comprises an oil storage bucket, an oil conveying pipe and a piston, and one end of the push rod is fixed to the piston; one end of the spring is fixed to the bottom of the liquid storage pool, and the other end of the spring is fixed to the bottom of the oil storage bucket; one end of the oil conveying pipe communicates with the oil storage bucket, and the other end of the oil conveying pipe communicates with the oil storage box; and the oil storage bucket is provided with a first one-way valve, and the oil pipe is provided with a second one-way valve. The device is adopted to performing coating on the plastic plate, the blister varnish in the liquid storage box can maintain a certain quantity, manual supplementation is not needed, and the work amount of workers is lowered.

Description

technical field [0001] The invention belongs to a device for spraying, pouring or allowing liquid or other fluid substances to flow onto the surface of a workpiece, in particular to a coating device for plastic plates. Background technique [0002] In the production process of plastic sheets such as PET, in order to improve the wear resistance and antistatic performance of the plastic sheets, it is usually necessary to coat the upper and lower surfaces of the plastic sheets with PET quick-drying wear-resistant environmental protection plastic oil. Dry after oiling, non-sticky, slippery, anti-scratch, wear-resistant and other characteristics. At present, a lot of enterprises all adopt manual mode to carry out oiling to plastic plate, adopt this method, the labor intensity of worker is bigger but production efficiency is not high, and the coating that forms after oiling is uneven. [0003] The Chinese invention patent with the publication number CN103317648 A discloses a pres...
