When defective products appear, the existing technology is to notify the operators on the line through the alarm device to select and reject the defective products; when the operation When the operator walks away for a while or does not hear the alarm, the defective products will flow into the good products, affecting the quality of the shipment, and for the paper bags produced automatically, leaving the operator to remove the paper bags causes a waste of labor, which is not conducive to the business. High benefit development.

Utility model content

The technical problem to be solved by the utility model is: to provide a device for preventing defective waste bags from continuing to circulate on the production line.

The solution of the utility model to solve the technical problem is: a waste bag rejecting mechanism, including a transport belt, a bracket, and a rejecting device, the rejecting device is located at the end of the transport belt, and the rejecting device includes a cylinder, a pinch belt group, supporting plate, driving motor; the pinch belt set includes an inlet and an outlet, the pinch belt set is composed of a driving belt located below and a driven belt located above, the belt surface of the driving belt and the driven belt The belt surface of the cylinder is in contact with each other; the drive motor drives the active belt to circulate; the cylinder is located below the conveyor belt, and the cylinder rod elongation direction forms an obtuse angle with the forward direction of the conveyor belt; the inlet of the pinch belt set The moving direction of the piston rod is substantially parallel to the extending direction of the piston rod; the support plate is located below the outlet of the pinch belt set.

As a further improvement of the above technical solution, a push rod is connected to the front end of the piston rod, and the outer periphery of the push rod is covered with a rubber layer.

As a further improvement of the above technical solution, a tension roller is provided on the lower side of the driving belt, and the tension roller is movably connected with the frame.

The beneficial effects of the utility model are: the utility model automatically sends the unqualified online products to the pallet through the waste bag rejecting mechanism, avoiding bad products from flowing into the next process, improving the quality stability of the enterprise's products, reducing the operating costs of the business. Moreover, the paper bag transmission is carried out by using the pinch belt set, and the transmission is stable and reliable.

Description of drawings

In order to illustrate the technical solutions in the embodiments of the present invention more clearly, the following will briefly describe the accompanying drawings that are used in the description of the embodiments. Apparently, the drawings described are only some embodiments of the utility model, not all embodiments, and those skilled in the art can also obtain other designs and drawings according to these drawings without creative work.

Fig. 1 is a structural representation of the utility model.

Detailed ways

The idea, specific structure and technical effects of the present utility model will be clearly and completely described below in conjunction with the embodiments and accompanying drawings, so as to fully understand the purpose, characteristics and effects of the present utility model. Apparently, the described embodiments are only some of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, other embodiments obtained by those skilled in the art without paying creative efforts, All belong to the protection scope of the utility model. In addition, all the connection/connection relationships mentioned in this article do not refer to the direct connection of components, but mean that a better connection structure can be formed by adding or reducing connection accessories according to specific implementation conditions. The various technical features in the invention can be combined interactively on the premise of not conflicting with each other.

Referring to Fig. 1 , a waste bag rejecting mechanism includes a conveyor belt 1, a bracket 3, and a rejecting device 2, which is located at the end of the conveying belt 1, and the rejecting device 2 includes a cylinder 21, a pinch belt set 22. Support plate 23, driving motor 24; said pinch belt set 22 includes an inlet and an outlet, said pinch belt set 22 is composed of a driving belt located below and a driven belt located above, the belt surface of the driving belt It abuts against the belt surface of the driven belt; the driving motor 24 drives the driving belt to circulate; the cylinder 21 is located below the conveyor belt 1, and the extension direction of the piston rod of the cylinder 21 forms an obtuse angle with the forward direction of the conveyor belt 1 , the movement direction of the inlet of the pinch belt set 22 is substantially parallel to the direction of piston rod extension; the support plate 23 is located below the outlet of the pinch belt set 22 .

During normal production, the paper bag is transported along the direction A. When the paper bag is found to be defective during production, the cylinder receives an action signal. When the paper bag is transported to the cylinder, the piston rod of the cylinder stretches out, and the paper bag enters the rejecting device and is transported along the direction B. Enter the pallet. The paper bag is transported in the rejection device and is clamped by two belts, so the transport is reliable.

As a further preferred embodiment, the front end of the piston rod is connected with a push rod, and the outer periphery of the push rod is covered with a rubber layer.

As a further preferred embodiment, a tension roller is provided on the underside of the driving belt, and the tension roller is movably connected with the frame. The tension roller can adjust the tightness of the belt, which is suitable for the production needs of paper bags of different thickness.

The preferred embodiments of the present utility model have been specifically described above, but the present invention is not limited to the described embodiments, and those skilled in the art can also make various equivalent modifications or modifications without violating the spirit of the present utility model. Replacement, these equivalent modifications or replacements are all included within the scope defined by the claims of the present application.
