Shearing machine for oblique planes at ends of packaging strips

Abstract

The invention discloses a shearing machine for oblique planes at the ends of packaging strips. The shearing machine comprises a worktable, a shearing unit, a guiding unit and a framework. The worktable is used for accommodating the packaging strips to be shorn, the shearing unit is used for shearing the packaging strips, the guiding unit is used for guiding cutters in the shearing unit, the framework is used for supporting and fixing the shearing unit, the guiding unit is arranged above the worktable, a conveying channel for conveying the packaging strips is arranged below the guiding unit, two cutter guiding grooves which are distributed along a packaging strip conveying direction are formed in the guiding unit, the two cutters which are respectively used for shearing the front ends and the tail ends of the packaging strips to form the oblique planes at the ends of the packaging strips are arranged in the shearing unit, are respectively arranged in the two cutter guiding grooves of the guiding unit and are respectively connected with two crank arms hinged onto the framework, and the crank arms are driven by cylinders to swing around hinged joints to drive the cutters to reciprocate along the cutter guiding grooves, so that the packaging strips which pass the conveying channel can be shorn. The shearing machine has the advantages that the shearing machine is reasonable in design and simple in structure, and can be operated easily and conveniently, the labor intensity of workers can be effectively reduced, and the production efficiency can be improved.

Description

technical field [0001] The present invention relates to a shearing machine, and more particularly to a shearing machine for beveling the ends of packaging strips. Background technique [0002] The packaging strips used in the packaging industry often need to be processed with an inclined surface at the end for the perfect butt joint of three packaging strips at a three-dimensional packaging corner during packaging. Based on this purpose, the processing angle accuracy of the inclined surface The requirement is higher, and the inclined plane shearing machine in the prior art is a manual shearing machine, which is powered by manpower to carry out the shearing work to the packaging strips, resulting in a large workload of shearing and a relatively high labor intensity of the workers. [0003] In addition, the structure of the shearing machine in the prior art is relatively complicated, including many cantilever beam structures, and the shape and position tolerance requirements o...

Problems solved by technology

[0002] The packaging strips used in the packaging industry often need to be processed with an inclined surface at the end for the perfect butt joint of three packaging strips at a three-dimensional packaging corner during packaging. Based on this purpose, the processing angle accuracy of the inclined surface The requirements are relatively high. The inclined plane shearing machine in the prior art is a manual shearing machine, which is powered by humans to cut the packaging strips, resulting in a large workload for cutting and relatively high labor intensity for workers.

[0003] In addition, the structure of the shearing machine in the prior art is relatively complicated, including many cantilever beam structures, and the shape and position tolerance requirements of many parts are relatively high, making the production of parts difficult; After assembly, debugging is required. The debugging includes the adjustment of the position of the packaging strip of the cut piece, the synchronization adjustment of the movement of the two cutters, the adjustment of the cutting depth of the two cutters, etc. There are as many as ten debugging positions, and the difficulty of debugging is relatively high. Large, it is difficult for ordinary workers to debug successfully. Even experienced technicians need to spend tens of minutes, often about 40 minutes, to debug, which brings a lot of trouble to the manufacturer; in addition, in the equipment of the prior art The guides of the two cutting knives are supported by the rollers, which is easy to cause the sliding of the cutting knives in the width direction of the blade, resulting in poor control of the cutting position and the cutting effect cannot be guaranteed
