Description

Counting and conveying device for cover body

Technical Field

The utility model relates to the technical field of conveying devices in cover production equipment, in particular to a conveying device with a counting function for a cover.

Background

Many foods in the existing market are contained by adopting a metal can, a thin cover body (also called a thin cover) is arranged on a can opening of the metal can, in order to reduce pollution to the cover body in the transportation process, after the cover body is processed, a certain number of cover bodies are required to be tightly piled and stacked to form a cylinder body, the cylinder body is conveyed to a film wrapping machine, and films on the film wrapping machine are utilized for packaging and leaving a factory. The counting and conveying device of the cover body is connected between the outlet end of the cover body processing equipment and the inlet end of the film wrapping machine, counts the produced cover bodies, and sends the cover bodies into the film wrapping machine as a packaging unit according to a certain number of cover bodies so as to carry out subsequent packaging operation.

At present, the counting and conveying device of the cover body comprises a conveying part and a counting part, wherein the conveying part comprises a front conveying part arranged at the outlet end of the cover body processing equipment and a rear conveying part arranged at the inlet end of the film wrapping machine, and the counting part is arranged between the front conveying part and the rear conveying part so as to count the cover bodies from the front conveying part one by one and then transfer the cover bodies to the rear conveying part for quantitative conveying. Such a counting and conveying device is disclosed in the document CN215557291U, and the counting part includes rollers installed on both sides of the front conveying part and separating the cover body one by one, a counter corresponding to the rollers, and a pushing part pushing the counted cover body from the rear conveying part to the next process. By adopting the cover counting and conveying device, the covers can be ensured to be accurately counted through the roller one by one stably.

However, the cover counting and conveying device is only applicable to cover counting and conveying in which the front conveying part and the rear conveying part are substantially on the same horizontal plane. In reality, since the front and rear conveying sections are mounted on different devices, there is a high possibility that there is a difference in height between the front and rear conveying sections, and the difference in height may be different for different devices. Secondly, when the stacked covers enter the counting part from the front conveying part, the covers can be separated through the spiral grooves on the roller, but as the covers enter the roller from the spiral grooves at the thinner end of the roller (the width of the grooves is close to the thickness of the covers), the covers sent from the front conveying part are stacked with each other, so that traction exists between the adjacent covers, the stacked covers can prevent the single cover from smoothly entering the thinner spiral grooves to a certain extent, and under the double influence, the phenomenon of scratching or crushing edges of the covers often occurs in the conveying process, thereby causing the scrapping of the covers, and finally, the scrapping rate of the covers is obviously increased.

Therefore, there is a need for further improvements to the current cap counting and conveying device.
