Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of plastic bottle processing, in particular to a plastic bottle mouth trimming device. Background Art
[0002] Plastic bottles are mainly made of materials such as polyethylene or polypropylene and added with a variety of organic solvents. After adding the corresponding organic solvents, they are heated at high temperature and then blow molded, extruded, or injection molded through plastic molds. They are plastic containers that are not easy to break, have low cost, high transparency, and are made of food-grade raw materials.
[0003] During the production and processing of plastic bottles, there will be residual material at the bottle mouth after blow molding, which needs to be cut and trimmed using a cutting device. During cutting, it is generally necessary to use a clamp to fix it. The fixing method in the prior art is generally to use a clamp that matches the bottle body to clamp both sides of the bottle body. Since the material of the plastic bottle body is relatively thin, the pressure exerted by the blade on the bottle mouth during cutting may cause deformation of the connection between the bottle mouth and the bottle body, thereby causing an uneven incision. Secondly, the interior of the clamp is designed to be arc-shaped, which makes the clamp only adapt to plastic bottles of a specific size and cannot flexibly adapt to other sizes, reducing the practicality of the device.
[0004] Therefore, it is necessary to design a plastic bottle mouth-repairing device to solve the above problems. Utility Model Content

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0024] Reference Figure 1-5 A plastic bottle mouth trimming device comprises a mounting frame 1 assembled on a conveying device, a cutting device 2 for cutting the bottle mouth is mounted on the mounting frame 1, the cutting device 2 is composed of a blade and a driving device, the blade can be moved to a position close to the waste material under the action of the driving device, and then rotates one circle under the action of the driving device to cut the residual material, the specific structure and working principle of the cutting device 2 are both prior art, and are not an innovative part of the present utility model, and will not be described in detail here, an electric telescopic rod 12 is fixedly connected to the mounting frame 1, the telescopic end of the electric telescopic rod 12 passes through the top of the mounting frame 1, and the telescopic end of the electric telescopic rod 12 is fixedly connected to a fixing frame 3, a plurality of clamping blocks 5 for fixing the bottle mouth are provided on the fixing frame 3, and a moving component for driving the clamping blocks 5 to move is provided on the fixing frame 3.
[0025] Reference Figure 3 and Figure 5The movable assembly comprises a fixed plate 4 fixedly connected to the side wall of the fixed frame 3, a sleeve 6 is rotatably connected to the fixed plate 4, an opening 11 coaxial with the sleeve 6 is provided on the sleeve 6, a guide opening 7 having the same number as the clamping block 5 is penetrated through the sleeve 6, a guide block 8 is provided in the guide opening 7, the bottom end of the guide block 8 is fixed to the top of the clamping block 5, a slider 10 is fixedly connected to the bottom of the clamping block 5, and a slide groove 9 having the same number as the clamping block 5 is provided on the fixed plate 4. Under the mutual cooperation of the guide opening 7 and the guide block 8, and the limiting action of the slider 10 and the slide groove 9, the clamping block 5 can move toward the center direction of the opening 11, so that the periphery of the bottle mouth can be fixed, replacing the traditional method of fixing the bottle body, effectively preventing the deformation of the plastic bottle during the cutting process, thereby ensuring the flatness of the incision, the slider 10 is slidably connected to the inner side of the inner side of the slide groove 9, and the movable assembly also comprises a driving member for driving the sleeve 6 to rotate.
[0026] Reference Figure 2 The driving member includes a motor 15 fixedly connected to the bottom of the fixing frame 3, the output shaft end of the motor 15 passes through the bottom of the fixing frame 3, and the output shaft end of the motor 15 is fixedly connected to a gear 14. A gear ring 13 is fixedly sleeved on the sleeve 6, and the gear ring 13 is meshed with the gear 14. The motor 15 drives the sleeve 6 to rotate and then drives the movement of the clamping block 5. The different moving distances of the clamping block 5 are adapted to different bottle mouth diameters. In this way, when processing plastic bottles of different specifications, production costs can be saved.
[0027] Reference Figure 4 A card slot 16 is provided on the side wall of each clamping block 5 in the direction of the center of the opening 11, and an air bag 17 is fixedly connected inside the card slot 16. The air bag 17 can fill the thread of the bottle mouth, thereby increasing the contact area of the clamping block 5 on the bottle mouth, improving the firmness of the device fixing the bottle mouth, and at the same time preventing the surface of the bottle mouth from wear, thereby ensuring the processing quality of the plastic bottle.
[0028] Reference Figure 2 All the clamping blocks 5 are arranged at equal intervals in the circumferential direction, so that the force applied by the clamping blocks 5 to the bottle mouth can be evenly distributed, ensuring the stability of the clamping blocks 5 fixing the bottle mouth.
[0029] Reference Figure 2 , Figure 3 and Figure 5 The cross section of the fixing plate 4 is annular, and the center of the fixing plate 4 is coaxial with the center of the opening 11, so that the bottle mouth can pass through the opening 11, thereby improving the stability of the overall structure of the device.
[0030] The specific working principle of the utility model is as follows:
[0031] When working, the electric telescopic rod 12 is started, and the telescopic end of the electric telescopic rod 12 moves downward to drive the fixing frame 3 to move downward, so that the fixing plate 4 and the sleeve 6 can surround the mouth of the plastic bottle, and then the motor 15 is started, and the output shaft of the motor 15 rotates to drive the gear 14 to rotate, so that the gear 14 and the sleeve 6 rotate, and then the guide port 7 rotates together, and the rotation of the guide port 7 drives the guide block 8 and the clamping block 5 to move. At the same time, under the limiting action of the slide groove 9 and the slider 10, all the clamping blocks 5 can move as a whole toward the center direction of the bottle mouth, so that the clamping block 5 can apply pressure to the bottle mouth to fix the bottle mouth, and then the cutting device 2 is started to cut the residual material. Since the material of the bottle mouth is hard and not easy to deform, and the force applied by the clamping block 5 to the bottle mouth is evenly distributed, the plastic bottle will not be deformed or shifted during cutting, thereby ensuring the accuracy and quality of cutting. Secondly, the different moving distances of the clamping block 5 are adapted to different bottle mouth calibers, which improves the practicability and flexibility of the device and saves production costs.
[0032] Furthermore, an airbag 17 is provided on the side wall of the clamp block 5 facing the bottle mouth. Since a thread matching the bottle cap is provided at the bottle mouth, when the clamp block 5 abuts against the bottle mouth, the airbag 17 is squeezed and deformed, and then can fill the depression of the thread. This increases the contact area between the device and the bottle mouth, ensuring the stability of the bottle mouth fixation. At the same time, the airbag 17 also protects the bottle mouth, preventing the clamp block 5 from causing wear on the bottle mouth, thereby ensuring the processing quality of the plastic bottle.
[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
