Description

Technical Field

[0001] The utility model relates to the technical field of papermaking, in particular to an automatic cleaning device for a guide roller protective cover. Background Art

[0002] Modern paper machines are running faster than before, and it is easy for sticky materials to form on the guide rollers during operation. Since the guide rollers are constantly rotating during normal operation, it is very dangerous to clean them manually, and safety accidents are very likely to occur; if the machine is stopped for cleaning, normal production will be delayed. If they are not cleaned, more and more materials such as paper pulp will adhere to them, and when the guide rollers rotate at high speeds, it is easy for sticky materials to fall off onto the protective cover, and eventually fall onto the paper, causing paper breaks, etc. This poses a major hidden danger to production operations, poor operation, and increased production problems, which will result in excessively high production costs and reduced profits. In view of the above technical problems, the present application proposes a new technical solution that can clean sticky materials and other materials on the guide rollers and their protective covers online to ensure safe and continuous production.

Compared with the prior art, an arc-shaped spray pipe is provided, a plurality of first nozzles are provided on the outside of the spray pipe, and a plurality of second nozzles are provided on the inside of the spray pipe, thereby realizing online automatic water spray cleaning of the guide roller and its protective cover, thereby ensuring safe and continuous production. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 This is a structural principle diagram of the automatic cleaning device for the guide roller protective cover provided by the utility model. DETAILED DESCRIPTION

[0013] The utility model provides an automatic cleaning device for a guide roller protective cover. In order to make the purpose, technical solution and effect of the utility model clearer and more specific, the utility model is further described in detail below. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0014] See also Figure 1 The utility model provides an automatic cleaning device for a guide roller protective cover. The accompanying drawings are only used to explain the structural principles and are not proportional to the actual products. The accompanying drawings only show the structures related to the invention point of this application, and some conventional structures are not specifically drawn. The terms "first", "second", etc. described herein are merely different names for similar structures for the purpose of explanation, and are not intended to limit this application. The "multiple" (or "several") mentioned herein refers to an indefinite number, because the number of structures referred to is not an invention point, and therefore is not specifically limited. For ease of understanding, the accompanying drawings show a guide roller 91 and a guide roller protective cover 92.

[0015] An automatic cleaning device for a guide roller guard cover includes a water inlet pipe 1 and a spray pipe 4 arranged inside the guide roller guard cover 92. The spray pipe 4 is arc-shaped, and the inlet end of the spray pipe is connected to the water inlet pipe; a plurality of first nozzles 51 are arranged on the outside of the spray pipe, and a plurality of second nozzles 52 are arranged on the inside of the spray pipe. It can be observed from the accompanying drawings that the spray pipe and the guide roller guard cover 2 are arranged concentrically.

[0016] Furthermore, the first nozzle and the second nozzle are arranged alternately, which prevents the first nozzle and the second nozzle from being too close to each other, thereby ensuring that the nozzles can be arranged normally.

[0017] Preferably, the first nozzles are arranged at the same interval, and the second nozzles are arranged at the same interval. This arrangement ensures that the first nozzles spray water uniformly toward the outside, and the second nozzles spray water uniformly toward the inside.

[0018] Preferably, the specifications of the first nozzles are the same, and the specifications of the second nozzles are the same.

[0019] In order to further improve the cleaning effect, the following configuration can be made: the spray pipe is rotatably connected to the guide roller guard, and the guide roller guard automatic cleaning device further comprises a driving device 7 for driving the spray pipe to rotate. That is, the driving device drives the spray pipe to rotate within a certain angle range, so that the water sprayed from the first nozzle and the second nozzle covers a larger area.

[0020] The rotatable connection between the spray pipe and the guide roller guard can be achieved in many ways. Here, a relatively simple solution is provided: a straight pipe 3 (specifically a round pipe) is provided at the inlet end of the spray pipe, and the straight pipe passes through the guide roller guard; a straight rod 6 (specifically a round rod) is connected to the end of the spray pipe, and the straight rod passes through the guide roller guard. That is, two round holes are correspondingly opened on the guide roller guard (not visible in the figure), and the straight pipe and the straight rod can pass through the corresponding round holes respectively. The straight pipe can be connected to the water inlet pipe through a hose 2 (or a quick connector, etc.) to ensure that the spray pipe can rotate normally.

[0021] Preferably, the driving device 7 is a reduction motor (including a motor and a reduction box), and the output shaft 71 of the reduction motor is connected to the straight rod. That is, the reduction motor directly drives the straight rod to rotate to realize the rotation of the spray pipe.

[0022] In actual use, the water inlet pipe is connected to a water pump (or a factory circulating water pipe, etc.), and the flow rate of the spray water is changed by adjusting the valve 11 on the water inlet pipe. The first nozzle is used to spray water toward the guide roller protective cover, and the second nozzle is used to spray water toward the guide roller. The reduction motor drives the spray pipe to rotate within a certain range, further increasing the coverage of the water sprayed by the first nozzle and the second nozzle, that is, improving the cleaning range and cleaning effect.

[0023] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and the utility model concept of the utility model, and all these changes or substitutions should fall within the protection scope of the utility model.
