Rib trimming device for injection-molded food container

Abstract

The rib edge trimming device comprises an operation plate, a support seat, a sample disc, a detection disc and a supporting plate, the top of the support seat is provided with a sample disc, the bottom of the supporting plate is connected with a rotating rod, a starting assembly is connected to the top of the support seat, and the starting assembly is aligned with a calibration sample and an open rib edge of a to-be-detected container. A rotating part is arranged at the bottom of the starting assembly, the two ends of the rotating part are connected with the two rotating rods correspondingly, and the finished product comparing and trimming part conducts synchronous detection on the detection tracks of the open rib edge and the bottom rib edge compared with the reference sample comparing part. The calibration sample and the to-be-detected sample which are qualified in size design are compared and checked, comparison is carried out according to the synchronously-detected rib edge size, standard calibration of the opening rib edge and the bottom rib edge of an existing cylindrical food container is facilitated, the calibration efficiency is improved, and the detection accuracy is improved. And the trouble of missing or inconvenience in repairing in the existing manual detection process is reduced.

Description

technical field [0001] The invention relates to the technical field of container processing, in particular to a rib trimming device for injection-molded food containers. Background technique [0002] Food packaging has many functions. The primary purpose is to preserve food, protect food from external physical, chemical and microbial influences, maintain food quality, prolong food storage period, and use sealed packaging containers to make food processing, storage, transportation, and sales. It can be carried out in an industrialized way, so that scattered food processing and skills can be developed into food engineering and industry. [0003] There are many types of food packaging, metal packaging containers made of metal material die-casting, plastic bags and other packaging food, and plastic food containers that are injection-molded. It is more difficult and expensive than injection molding. Food containers such as plastic bags are often damaged during use. Therefore, in...

Problems solved by technology

[0004] Existing injection-molded food containers are injection-molded by feeding plastic materials for production into the injection molding machine. For injection-molded food containers with edges such as rectangular bodies, the overall shape of the container can be kept unchanged through the strengthening of the edges. It is easy to use to keep food and containers from deformation, but for cylindrical injection molded food containers, ribs are added to the top opening of the cylindrical injection molded food container to increase the strength of the opening, and at the same time Ribs are added to the inner wall of the bottom of the shaped injection molded food container for bottom strength. During the injection molding process, the molten plastic is poured into the injection mold through the pouring port of the injection molding machine to form the entire product. The molding of the entire cylinder is based on the plastic The flow rate is uniform, but for the ribs at the opening and bottom of the cylinder, after the molding is completed, the finished product will be released from the mold through the demoulding mechanism. The rib forming is slower than the cylinder forming, and the demoulding During the process, it is easy to cause the ribs to crack or the thickness dimension of the molding is quite different from the designed rib size. In the case of processing, the employees only use the deburring knife to remove the surface burrs, so that the ribs with cracks or the size difference ( The rib pulls out the molded plastic part during the demoulding process, which is repaired as a burr) and enters the market for use, causing deformation and damage to the injection molded food container. Since the rib is injection molded on the inner wall and bottom of the container opening, the bottom of the rib and the container It is easy for employees to observe and inspect the fitting place, and it is not convenient for employees to perform standard trimming on the container rib when cracks appear at the joint position of the rib at the opening and the bottom rib and the container or the rib molding size is satisfied
