Description

Technical Field

[0001] The utility model relates to the technical field of plastic bottle production, in particular to a device for cutting waste material from the mouth of a plastic bottle. Background Art

[0002] Plastic bottles are mainly made of materials such as polyethylene or polypropylene and added with a variety of organic solvents. Plastic bottles widely use polyester (PET), polyethylene (PE), and polypropylene (PP) as raw materials. After adding corresponding organic solvents, they are heated at high temperature and then blow molded, extruded, or injection molded through plastic molds. They are mainly used for liquid or solid disposable plastic packaging containers such as beverages, foods, pickles, honey, dried fruits, edible oils, pesticides and veterinary drugs. Plastic bottles are not easy to break, low cost, high transparency, and food-grade raw materials.

[0003] After the plastic bottle is demoulded, local burrs and rubber heads will be formed around the bottle mouth, which not only affects the appearance of the bottle mouth, but also may cause safety hazards. The rubber heads and burrs at the existing plastic bottle mouths are manually operated, which is not only inefficient and difficult to meet mass production needs, but also difficult to maintain consistent rubber cutting effects. The residual burrs will affect the overall quality of the plastic bottle. Therefore, a plastic bottle mouth waste cutting device is proposed to solve the above-mentioned problems. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes a device for cutting waste from the mouth of a plastic bottle, comprising a frame, a sliding rod fixedly mounted on the frame, a sliding block slidably connected to the sliding rod, a driving member for controlling the movement of the sliding block is arranged on the frame, a fixing plate is fixedly mounted on one side surface of the sliding block, a clamping assembly for limiting the position of the plastic bottle is arranged on the fixing plate, the frame is provided with a mounting plate, a moving member is arranged on one side surface of the mounting plate, and a rubber cutting assembly is arranged on the moving end of the moving member.

[0005] Furthermore, the clamping assembly includes a first one-way cylinder, which is fixedly installed at the bottom end of the fixed plate. A movable plate is provided at the telescopic end of the first one-way cylinder. A limiting rod with one end penetrating through and extending to one side of the fixed plate is fixedly installed on the side surface of the movable plate close to the fixed plate. The first mold and the second mold are respectively fixedly installed on the opposite side surfaces of the fixed plate and the movable plate.

[0006] Furthermore, the moving part includes a second one-way cylinder, which is fixedly mounted on the bottom of the mounting plate.

A rack is fixed to the telescopic end of the electric push rod. The rack and the electric push rod are horizontally arranged, and the rack passes through the connecting block. The connecting block is rotatably connected to a vertically arranged shaft, and a gear meshing with the rack is fixedly installed on the outer side of the shaft. A cutting blade is detachably connected to the bottom end of the shaft.

[0008] Furthermore, it includes a clamping member, which is arranged at the bottom end of the rotating shaft and is used to fix the cutting blade.

[0009] The beneficial effects of the utility model are as follows: the utility model uses a clamping component to fix the plastic bottle by closing the first mold and the second mold, while ensuring that there is no obstruction around the bottle mouth, and a cutting component is set to drive the cutting blade to rotate axially to cut the rubber head. A moving part is also provided to drive the rotating cutting blade to move forward and backward, thereby increasing the cutting coverage area and removing burrs to the greatest extent. Compared with the existing technology, the burrs and rubber heads at the bottle mouth of the plastic bottle can be cut to the greatest extent through the rotation and movement of the cutting blade, thereby improving the overall production efficiency, and at the same time, each bottle mouth can be processed in a precise and consistent manner to ensure that the product is consistent in appearance and quality.
