Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of automatic coding machine feeding mechanism in coding equipment technical field. BACKGROUND

[0002] For tobacco round bar products or the same round bar product processing production process, when facing the link of adding product mark, generally mark is handled by marking machine, and the quantity of this kind of product is more, and each needs to be marked with corresponding mark or code, so continuous conveying is carried out by relying on automatic conveying equipment, and the product is sent to the marking position according to the established conveying route, and then the mark or code is added.

[0003] The current coding conveying equipment generally realizes the continuous conveying of products by conveying belt, and when the product reaches the set position, it is slowed down and stopped synchronously, and then coding is carried out, and subsequent transfer operation is carried out; the subsequent product is realized by repeating the same steps one by one. The feeding mechanism for sending the product to the coding position is not separately provided in the traditional coding machine, and the product is conveyed from the feeding position and directly passes through the coding position.

[0004] The traditional processing process has some shortcomings, including:

[0005] 1. The precision of the equipment is low, and the maintenance workload is large. The traditional equipment continuously conveys products by conveying belt, and cannot guarantee the accuracy of the stopping position each time, which affects the coding effect; at the same time, the high-frequency start-stop operation greatly damages the equipment, shortens the service life of the equipment, and further reduces the precision of the equipment after a long time of use.

[0006] 2. The product storage and picking are not fast and accurate enough. The products are generally collected and stored by batch collection and stacking, and multiple products are conveyed at the same time, which can easily cause product confusion. The traditional equipment cannot convey and store single products, so it is easy to cause product damage and reduce the qualified rate.

[0007] It can be seen that the automatic coding machine feeding mechanism now still needs to be improved, and should be optimized to improve the automation of the coding machine, so as to improve the accuracy of coding single products, improve the control accuracy of conveying and storing single products, and improve the overall quality of products. Therefore, a more reasonable technical scheme is needed to solve the technical problems in the prior art. CONTENT OF THE UTILITY MODEL

When the above scheme is used, the guide inclined plate limits the movement direction of the push head, and the push head moves reciprocally in the movement direction, so that the transfer of product is realized. The crank assembly drives the push head to move once, and one product is transferred to the product conveying mechanism, so that single product transfer is ensured at a time, the accuracy of transfer is improved, and product damage caused by product accumulation and backlog is avoided.
