Description

Technical Field

[0001] The utility model relates to a quick-freezing device, in particular to a lubricating device for a conveyor belt of a quick-freezing device. Background Art

[0002] The existing conveyor belts of quick-freezing devices are mainly made of plastics such as stainless steel and ultra-high molecular weight polyethylene, and the guide rails are generally made of plastics such as ultra-high molecular weight polyethylene. During long-term use, the conveyor belt and the guide rail continuously rub against each other, which is extremely easy to cause wear on the lower surface of the conveyor belt and the upper surface of the guide rail, resulting in an increase in the friction force between the conveyor belt and the guide rail, an increase in the motor load, and the debris generated by the wear may fall on the produced products, causing pollution to the products. At the same time, the debris falling into the mechanical gaps will also pose a safety hazard to the equipment. Summary of the Invention

Electric telescopic rods are installed below the left and right support rods of the mounting frame. A plurality of roller brushes are arranged below the cross bar of the mounting frame. The roller brushes are vertically installed above the conveyor belt. A flow-dividing aluminum block and an oil-dropping nozzle are arranged above each roller brush. A quick connector and a distributor are arranged on the mounting frame. The distributor is communicated with the flow-dividing aluminum block through an oil inlet pipe.

[0004] A further improvement of the utility model lies in that: an adjustable bottom foot frame is arranged at the bottom of the electric telescopic rod.

[0005] A further improvement of the utility model lies in that: a rotation detection device is installed on the shaft sleeve of each roller brush.

[0006] A further improvement of the utility model lies in that: the lubricating oil is evenly dripped on the roller brushes by the flow-dividing aluminum block and the oil-dropping nozzle through the oil inlet pipe.

[0007] A further improvement of the utility model lies in that: there are three roller brushes, and the distributor is a one-in-three-out distributor.

[0008] The utility model has the following advantages compared with the prior art:

[0009] The utility model is installed at the tensioning and returning place of the conveyor belt of the quick-freezing machine, and is mainly used for automatic lubrication of the conveyor belt, reducing the friction between the conveyor belt and the guide rail, and prolonging the service life of the equipment.

Detailed implementation manners

[0013] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. The elements and features described in one embodiment of the present utility model can be combined with those shown in one or more other embodiments. It should be noted that for the sake of clarity, the representation and description of components and processes that are irrelevant to the present utility model and known to those of ordinary skill in the art are omitted in the description. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present utility model.

[0014] As Figure 1 shown, a lubricating device for a conveyor belt of a quick-freezing device, which is installed at the tensioning return of the conveyor belt of the quick-freezing machine and can be used singly or in multiple groups; the device includes a mounting bracket 5, an electric telescopic rod 2 is installed below the left and right support rods 5-1 of the mounting bracket 5, an adjustable footrest 1 is provided at the bottom of the electric telescopic rod 2, a plurality of roller brushes 6 are provided below the cross bar 5-2 of the mounting bracket 5, a rotation detection device 7 is installed on the sleeve of each roller brush 6, the roller brushes 6 are vertically installed above the conveyor belt 8, a shunt aluminum block 3 and an oil drip nozzle 4 are provided above each roller brush 6, a quick connector 9 and a distributor 10 are provided on the mounting bracket 5, the distributor 10 is communicated with the shunt aluminum block 3 through an oil inlet pipe 11, and lubricating oil is evenly dripped on the roller brushes 6 by the shunt aluminum block 3 and the oil drip nozzle 4 through the oil inlet pipe 11. Suppose there are three roller brushes 6, and the distributor 10 is a one-in-three-out distributor.

[0015] During the operation of the quick-freezing equipment, the PLC controller continuously detects the motor load torque value by reading the data of the frequency converter of the driving motor of the conveyor belt. When the motor load torque value is normal, the electric telescopic rod 2 extends, raising the upper part of the device and moving the roller brush 6 away from the surface of the conveyor belt 8. When it is detected that the motor load torque of the conveyor belt is too large, the oil pump starts, pumping low-temperature-resistant lubricating oil into the pipeline system. After passing through the quick connector 9 and the distributor 10, the lubricating oil enters the oil inlet pipe and is evenly dripped onto the roller brush 6 through the shunt aluminum block 3 and the oil dripping nozzle 4. At the same time, the electric telescopic rod 2 contracts, lowering the upper part of the device and bringing the roller brush 6 into contact with the surface of the conveyor belt 8. The roller brush 6 coats the lubricating oil on the surface of the conveyor belt 8. The PLC controller automatically adjusts the oil injection frequency and the amount of oil injection by reading the data of the driving motor frequency converter, lubricates the conveyor belt 8, reduces mechanical wear, while reducing the amount of oil used and preventing oil from dripping onto the products, which may affect the appearance of the products. When the conveyor belt 8 is lubricated in place, the electric telescopic rod 2 extends, raising the upper part of the device again and moving the roller brush 6 away from the surface of the conveyor belt 8, extending the service life of the roller brush 6. During the normal operation of the lubrication device, the rotation detection device 7 outputs a continuous rotation signal. Once it detects no rotation signal, it immediately outputs an alarm signal through the PLC controller, indicating that the roller brush 6 is worn and needs to be replaced in a timely manner.

[0016] This device is generally installed at the return structure of the conveyor belt 8, coating the lubricating oil on the reverse side of the conveyor belt 8 to achieve a better lubricating effect on the contact surface between the conveyor belt 8 and the guide rail.

[0017] Finally, it should be noted that although the present invention and its advantages have been described in detail above, it should be understood that various changes, substitutions, and transformations can be made without exceeding the spirit and scope of the present invention as defined by the appended claims. Moreover, the scope of the present invention is not limited to the specific embodiments of the processes, devices, means, methods, and steps described in the specification.
