Description

Technical Field

[0001] This utility model relates to the technical field of waste material removal devices for blow-molded products, and in particular to a waste material removal device for bottle mouths of blow-molded products. Background Technology

[0002] Plastic bottles are mainly made of materials such as polyethylene or polypropylene with the addition of various organic solvents. Plastic bottles widely use polyester, polyethylene, and polypropylene as raw materials. After adding the corresponding organic solvents, they are heated at high temperature and then formed into plastic containers through blow molding, extrusion blow molding, or injection molding using plastic molds. After blow molding, there will be some excess material at the bottle mouth. At this time, a bottle mouth cutting device is usually used to cut off the excess material at the bottle mouth.

[0003] In related technologies, bottle neck scrap cutting equipment generally cuts the bottle with the neck facing upwards. During the cutting process, plastic fragments or scraps are generated. Since the bottle neck is facing upwards, some of the fragments or scraps fall into the bottle body, causing the inside of the bottle to be contaminated. Utility Model Content

[0004] The purpose of this invention is to solve the problem that in the prior art, when the bottle opening is facing upwards during the cutting of bottle body waste, debris or scraps will fall into the bottle body. Therefore, this invention proposes a waste material cutting device for blow-molded products.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A device for cutting waste material from the bottle neck of a blow-molded product includes a support frame rotatably connected to a machine frame. The axis of rotation of the support frame is horizontally arranged. The support frame is rotatably connected to a plurality of inserts for inserting the bottle neck. A cutting mechanism is provided on one side of the insert at the highest point. The cutting mechanism can drive the insert at the highest point to rotate and cut the excess material from the bottle neck.

[0007] The cutting mechanism includes a power source, a third rotating shaft with its axis vertically arranged and rotatably connected to the frame, a circular cutting disc fixedly mounted on the third rotating shaft, a first rotating shaft with its axis vertically arranged rotatably connected to the bottom end of the third rotating shaft, a friction wheel fixedly mounted on the first rotating shaft, the power source being able to drive the first rotating shaft and the third rotating shaft to rotate at different speeds, and the friction wheel being able to drive the insertion post in contact with it to rotate.

[0008] The frame is fixedly mounted with a first rotary motor, and the power output shaft of the first rotary motor is connected to the support frame in a transmission manner.

[0009] There are four insertion posts, and the four insertion posts are distributed at equal angles on the outer periphery of the support frame.

[0010] Each of the inserts is equipped with at least one limiting rod at its top, and the limiting rod can abut against the bottom wall of the bottle.

[0011] A waste material receiving box is located below the support frame.

[0012] The friction wheel is covered with elastic rubber on its periphery.

[0013] The present invention provides a waste material cutting device for blow-molded product bottle mouths, which has the following advantages: when cutting the bottle body waste material with this device, because the bottle mouth is upside down and blocked by the insert post, the cutting debris and waste material will fall down and will not fall into the bottle body. After cutting, continue to rotate the support frame, and then pull off the cut bottle body. Attached Figure Description

[0014] Figure 1 This is a partial three-dimensional structural schematic diagram of the present invention;

[0015] Figure 2 This is a schematic diagram of the left-side structure of this utility model. Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figures 1-2 A blow molding product bottle mouth waste removal device includes a support frame 2 rotatably connected to the machine frame. The rotation axis of the support frame 2 is set horizontally. The support frame 2 is rotatably connected to a plurality of inserts 13 for inserting the bottle mouth of the bottle body 11. A cutting mechanism is provided on one side of the insert 13 at the highest point. The cutting mechanism can drive the insert 13 at the highest point to rotate and cut the excess material at the bottle mouth of the bottle body 11.

[0018] refer to Figure 1 , Figure 2 The worker manually or with the help of a robotic arm places the bottle neck onto the insert post 13, then rotates the support frame 2 to rotate the bottle body 11 to its highest position. At this point, the bottle body is in an inverted state. Then, the cutting mechanism drives the insert post 13 at the highest point to rotate and cut the remaining material at the bottle neck of the bottle body 11. Since the bottle neck is inverted and blocked by the insert post 13, the cutting debris and waste will fall down and will not fall into the bottle body. After the cutting is completed, continue to rotate the support frame 2, and then pull off the cut bottle body.

[0019] refer to Figure 2The cutting mechanism includes a power source, a third rotating shaft 10 with its axis set vertically and rotatably connected to the frame, a circular cutting disc 9 fixedly mounted on the third rotating shaft 10, a first rotating shaft 3 with its axis set vertically rotatably connected to the bottom end of the third rotating shaft 10, a friction wheel 4 fixedly mounted on the first rotating shaft 3, the power source being able to drive the first rotating shaft 3 and the third rotating shaft 10 to rotate at different speeds, and the friction wheel 4 being able to drive the insertion post 13 in contact with it to rotate.

[0020] The power source drives the first rotating shaft 3 and the third rotating shaft 10 to rotate at different speeds, causing the circular cutting blade 9 and the friction wheel 4 to rotate. The rotating friction wheel 4 drives the insert 13 in contact with it to rotate under the action of friction. The rotation of the insert 13 drives the bottle body on it to rotate. The rotating circular cutting blade 9 cuts off the excess material at the end of the rotating bottle body.

[0021] The frame is fixedly equipped with a first rotary motor 1. The power output shaft of the first rotary motor 1 is connected to the support frame 2 for transmission. The first rotary motor 1 drives the support frame 2 to rotate, so that the worker can insert a new bottle with one hand and cut the bottle with the other.

[0022] refer to Figure 1 There are four insertion posts 13, which are distributed at equal angles on the outer periphery of the support frame 2. Workers insert the bottle from the left and pull it out from the right, and then cut the remaining material from the bottle at its highest point.

[0023] Each insertion post 13 is equipped with at least one limiting rod 12 at its top. The limiting rod 12 can abut against the bottom wall of the bottle body 11, which can ensure that each bottle is inserted to the same depth, making the cutting length more accurate.

[0024] A scrap receiving box is located below the support frame 2. The annular scrap material after cutting will be placed on the insert post 13. When the insert post 13 is rotated to the downward tilt position, the scrap material falls into the scrap receiving box.

[0025] The friction wheel 4 is covered with elastic rubber. The elastic rubber improves the friction transmission effect on the insertion post 13 and makes it easier for the insertion post 13 to abut against the friction wheel 4.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any technical solution, concept, or design obtained by those skilled in the art by making equivalent substitutions or changes based on the technical solution and utility model concept disclosed in the present utility model should be included within the protection scope of the present utility model.
