Description

Technical Field

[0001] The utility model belongs to the technical field of noodle processing equipment, in particular to a calender cleaning mechanism. Background Art

[0002] The production of noodles is inseparable from the calendering process, which mainly makes the dough pass through a pair of relatively rotating rollers. The dough is compressed in the gap between the two rollers, stretched and thinned to become a continuous dough sheet.

[0003] After long-term use, the surface of the roller on the calender will inevitably be adhered to dough, resulting in reduced surface finish of the roller, which not only affects the continuity of the subsequent dough skin, but also affects the service life of the roller. At present, the common method to eliminate the problem of roller sticking is to set a scraper on each of the two rollers to clean the dough on the surface of the roller. However, the existing technology has the following problems: 1. The tightness of the contact between the scraper and the roller is poorly adjusted. When there are more dough on the roller, the cleaning is not thorough enough; 2. After long-term use, the scraper surface needs to be cleaned or replaced. Since the scraper is generally fixed on the mounting seat, the entire mounting seat needs to be disassembled and assembled, and the scraper replacement is cumbersome and maintenance is inconvenient.

[0028] like Figure 1 As shown, a calender cleaning mechanism comprises two shell plates 1 and 2 which are arranged opposite to each other, two pressure rollers 3 are rotatably mounted between the shell plates 1 and 2, and the front ends of the two pressure rollers 3 are provided with scraper shafts 4, one end of the scraper shafts 4 is rotatably mounted on the shell plate 2, and the other end of the scraper shafts 4 passes through the shell plate 1 and is fixedly mounted with a connecting seat 5, which is rotatably mounted on the shell plate 1;

[0029] A scraper seat 41 is provided at the front end of the scraper shaft 4, and a scraper 42 is fixedly mounted at the lower end of the scraper seat 41;

[0030] The scraper seat 41 is fixedly mounted on the scraper shaft 4 by bolts. The scraper seat 41 is fixed on the scraper shaft 4 by this bolt connection method, which is convenient for replacing the scraper 42, and is easy to disassemble and assemble and maintain.

[0031] The scraper 42 is made of tin-zinc-copper.

[0032] like Figure 2 As shown, the connecting seat 5 includes a fixed portion 51 and an extending portion 52 that are fixedly connected. The fixed portion 51 is rotatably mounted on the shell plate 1. One end of the scraper shaft 4 away from the shell plate 2 passes through the shell plate 1 and is fixedly connected to the fixed portion 51. An end of the extending portion 52 away from the fixed portion 51 is provided with a mounting hole 53.

[0033] The fixing part 51 is rotatably mounted on the shell plate 1, and the rotation of the extension part 52 can drive the rotation of the fixing part 51;

[0034] A connecting bolt 7 is provided above the extension portion 52, and a spring 71 is sleeved on the screw rod of the connecting bolt 7;

[0035] The head of the connecting bolt 7 is fixed on the shell plate 1;

[0036] A sprocket shaft 6 is provided below the extension portion 52. A sprocket 61 is sleeved on the outside of the sprocket shaft 6. A chain 62 is wound around the outside of the sprocket 61. One end of the chain 62 is fixed to the sprocket 61. The other end of the chain 62 passes through the mounting hole 53 and is fixedly connected to the spring 71.

[0037] The chain 62 is fixedly mounted in the mounting hole 53;

[0038] One end of the spring 71 is fixedly connected to the head of the connecting bolt 7, and the other end of the spring 71 is fixedly connected to the chain 62;

[0039] An adjusting screw 63 is fixedly mounted on the right end of the sprocket shaft 6, and one end of the adjusting screw 63 passing through the shell plate 1 is threadedly connected with a tightening nut 64;

[0040] The sprocket shaft 6 is fixed to the shell plate 1 through an adjusting screw 63 and a tightening nut 64.

[0041] The working process of the utility model is as follows:

[0042] When the scrapers 42 are not in operation, the two scrapers 42 are respectively away from the two pressure rollers 3;

[0043] When cleaning the two rollers 3 on the calender, tighten the sprocket shaft 6, so that the chain 62 drives the extension part 52 to rotate, so that the two scrapers 42 are closely fitted between the two rollers 3, and the sprocket shaft 6 is fixed by tightening the nut 64. The calender is started, and the two scrapers 42 are closely in contact with the two rotating rollers 3 to clean the surface of the two rollers 3.

[0044] After the scraper 42 is used, the scraper surface needs to be cleaned, so the scraper 42 needs to be moved away from the two pressure rollers 3, and then the scraper 42 is cleaned. The specific process is as follows: by loosening the tightening nut 64, the sprocket shaft 6 is loosened, and the chain 62 drives the extension part 52 to rotate, so that the two scrapers 42 are respectively away from the two pressure rollers 3, and then the surfaces of the two scrapers 42 are cleaned;

[0045] The close contact degree between the scraper 42 and the pressure roller 3 is adjustable, that is, it is adjusted by rotating the sprocket shaft 6. After the sprocket shaft 6 is adjusted, it can be fixed to the shell plate 1 by tightening the nut 64, which is convenient for operation and is conducive to thoroughly cleaning the surface of the pressure roller 3.

[0046] The scraper 42 used in the present invention is made of tin-zinc-copper;

[0047] Currently, brass is usually used as the scraper material on the market, and the roller body is centrifugally cast. Although the brass H62 material is relatively soft, it will still cause the smoothness of the roller to decrease and the surface to be damaged over time, and some fine black particles will fall from the scraper on the dough, causing pollution to the noodles. In view of these shortcomings, in addition to being able to meet the basic function of scraping noodles, the utility model does not damage the smoothness and surface integrity of the roller 3, and changes the scraper material from brass to tin-zinc-copper. Compared with brass, the scraper of this material is softer and contains an element that can lubricate, reduce the wear on the roller 3, and at the same time reduce the degree of damage to the surface smoothness of the roller 3, thereby increasing the service life of the calender and avoiding dough pollution.

[0048] The utility model provides a calender cleaning mechanism, which is easy to install and operate and suitable for practical use.
