Problems solved by technology

[0003] However, these industrial coated cloths require an accuracy error of ≤16g / m2, which is a great challenge for domestic coating machines, but most domestic coating machines have the following disadvantages: the coating knife mechanism of the coating machine is generally Including the knife rest and the lifting device connecting the knife rest, due to technical reasons, the rigidity of the knife rest is often not enough, and the knife rest is prone to bending or twisting under the action of its own weight and external force. A precise gap is formed between the roller busbars, which seriously affects the uniformity of the coating; and there is always a gap in the lifting device, and the adjustment accuracy of the tool holder is low, especially for the substrate coating with a width of 3600m. to this request
This not only restricts the improvement of my country's large-width high-precision coating machine manufacturing technology, but also restricts the development of large-width high-precision coated cloth products, thus affecting the progress of a series of related industries

Embodiment 1

[0029] Such as Figure 1-3 As shown, it includes a frame 1, a coating knife mechanism arranged on the frame 1, and a roller 3. The coating knife mechanism includes a coating knife 21, a knife rest 22 for installing the coating knife 21, a reinforcement device connecting the knife rest 22, and a connecting knife The lifting device of the frame 22 and the gap adjusting device for eliminating the internal gap of the lifting device, the gap adjusting device includes a gap eliminating part 251, and the roller 3 is provided with a reinforcement, the reinforcement is an inner support plate or an inner cylinder, and the inner support The plate and the inner cylinder are arranged inside the roller, and then threads or fins are added in the gap between the supporting plate or the inner cylinder and the roller to further improve its overall strength.

[0030] The reinforcing device includes a first reinforcing part 231 and a second reinforcing part 232. The first reinforcing part 231 is ...

Embodiment 2

[0035] The processing technology of the above-mentioned roller 3 is as follows: 1. Forming: bore the inner hole on the blank first, and then turn the outer circle to make the quality of the outer circle meet the requirements; 2. Reinforcement: add a support plate or The inner cylinder, and weld the reinforcement and the roller as a whole; 3. Stress relief: carry out stress relief treatment on the processed roller until it reaches the processing standard; 4. Subsequent treatment: finish turning and finishing Grinding, dynamic balancing and heat treatment are repeated until the final machining accuracy is achieved. The roller processed by the above processing method has good rigidity, high dynamic balance precision, is not easy to deform after long-term use, and rotates smoothly without jumping, which provides the basis for the precision of the coating. The radial runout of the roller has been increased from ≤0.012mm to ≤0.008mm; thus meeting the product requirements of the coat...

Embodiment 3

[0037] The rest are the same as the above-mentioned embodiment, the difference is that, as figure 2 As shown, the coating machine also includes an idler roller 7 for the carrier, a bending roller 8 for spreading, and a tension adjustment device 9 for adjusting the tension of the entire fabric, which is set in the opposite direction of coating by the coating knife 21 There is a material blocking mechanism 101 for blocking material (the material blocking mechanism is an existing technology, which will not be described in detail here), and a material receiving box for receiving the remaining paint on the roller is also arranged under the idler roller to avoid excess paint dripping into the equipment Or on the ground, pollute the environment, but also can be reused, saving and environmental protection.

[0038] Through the above-mentioned technical solution, the beneficial effect of the technical solution of the present invention is: the setting of the reinforcing device, the rei...

Abstract

The invention discloses a coating machine. The coating machine comprises a rack, a coating knife mechanism and a roller, wherein the coating knife mechanism is arranged on the rack and comprises a coating knife, a knife rest, a reinforcement device, a lifting device and a clearance regulating device; the knife rest is used for holding the coating knife; the reinforcement device is connected with the knife rest; the lifting device is connected with the knife rest; the clearance regulating device is used for eliminating an internal clearance of the lifting device and comprises a clearance elimination piece; a reinforcement piece is arranged on the roller. According to the coating machine provided by the invention, the knife rest is high in rigidity, unlikely to deform and high in regulation accuracy; large-scale coating operation can be realized.

Description

technical field [0001] The invention relates to the field of coated cloth manufacture, in particular to a coating machine. Background technique [0002] Scraping various coatings on the substrate, the formed composite coating products have a wide range of applications, and the coating methods are also various: roller coating, engraving printing, spraying, scraping coating, vapor deposition, pouring, dipping, etc., they It is used to manufacture different products, meet different needs and meet various precision requirements. Because knife coating is suitable for high-speed, large-width, and medium-precision coating requirements, these coated cloths are widely used in industries, stadiums, landscapes, highway toll stations, vehicle tarpaulins, soft joints for motor vehicles, military tents, inflatable Playgrounds, inflatable rubber boats, soft containers, water tanks, advertising materials and other fields. [0003] However, these industrial coated cloths require an accurac...
