Description

Technical Field

[0001] This utility model relates to the field of PE packaging bottle production technology, specifically a cutting device for PE packaging bottle production. Background Technology

[0002] In daily life, we often see PE plastic bottles used to store products such as water, cosmetics, or medicines. In order to ensure the shelf life of the products, the flatness of the bottle mouth is crucial. If the bottle mouth is not flat, even if the cap is put on, it cannot be sealed. After the plastic bottles are produced on the production line, the bottle mouth must be cut off.

[0003] Existing cutting devices for PE packaging bottle production typically use motor-driven cutting blades to cut the bottle necks of PE plastic bottles. However, the connection between the existing cutting blades and the motor is relatively fixed, which means that cutting can only be performed on PE plastic bottles of uniform size. It is inconvenient to adjust the position of the cutting blades according to plastic bottles of different diameters, making it inconvenient to use. Therefore, it is necessary to propose a cutting device for PE packaging bottle production to solve the above-mentioned problems. Summary of the Invention

[0004] The purpose of this invention is to provide a cutting head device for PE packaging bottle production, which features adjustable cutting blade position according to different diameter plastic bottles and is easy to use.

The output end of the motor passes through the bracket and is fixedly connected to an auxiliary plate. An L-shaped frame is fixedly connected to the lower end of the auxiliary plate. A second motor is installed at the upper end of the L-shaped frame. The output end of the second motor passes through the L-shaped frame and is fixedly connected to a lead screw. A horizontal plate is fixedly connected to the lower end of the L-shaped frame. The other end of the lead screw is movably connected to the horizontal plate. A slider is threaded onto the outer wall of the lead screw. A connecting rod is movably connected to the left end of the slider through a rotating shaft. A drive block is movably connected to the other end of the connecting rod through a rotating shaft.

[0006] A horizontal plate is fixedly connected to the lower end face of the L-shaped frame. A cross-shaped sliding groove is opened at the left end of the horizontal plate. The driving block is slidably connected to the sliding groove. A vertical plate is fixedly connected to the lower end face of the driving block. A cutting blade is installed on the lower end face of the vertical plate.

[0007] The upper end of the conveyor is equipped with a centering component.

[0008] To facilitate the limiting of the plastic bottles to be cut, in a preferred embodiment of the cutting head device for PE packaging bottle production according to this utility model, the centering component includes two fixed plates fixedly connected to the upper end of the conveyor. A first electric push rod is installed on the opposite side of the two fixed plates. The output ends of the two first electric push rods pass through the fixed plates and are fixedly connected to racks. Half gears are meshed on the outer walls of the two racks. Limiting plates are fixedly connected to the opposite sides of the two half gears.

[0009] To increase the smoothness of the drive block's movement, in a preferred embodiment of the cutting device for PE packaging bottle production according to this utility model, a spring is fixedly connected to the right end of the drive block, and the other end of the spring is fixedly connected to the slide groove.

[0010] To facilitate the movement of the drive support, in a preferred embodiment of the cutting device for PE packaging bottle production according to this utility model, a support plate is fixedly connected to the left end face of the conveyor, and a second electric push rod is installed on the lower end face of the support plate. The output end of the second electric push rod passes through the support plate and is fixedly connected to the support.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention involves starting a second motor to drive a lead screw to rotate. The rotation of the lead screw drives a slider to move downwards, which in turn drives a connecting rod to move downwards. The downward movement of the connecting rod pushes a drive block to slide inside a groove. As the drive block slides, it moves a vertical plate and a cutting blade, allowing the cutting blade to be inserted into the plastic bottle to be cut. Subsequently, a motor is started to drive an auxiliary plate to rotate, which in turn drives the L-shaped frame and the cutting blade to rotate. The rotating cutting blade performs the cutting operation on the plastic bottle, achieving the goal of adjusting the position of the cutting blade according to different diameter plastic bottles, thus providing convenience for use.

[0022] In this embodiment: First, the plastic bottle to be cut is centered using the centering component. Then, the second motor 24 is started to drive the lead screw 9 to rotate. When the lead screw 9 rotates, it drives the slider 11 to move downward. When the slider 11 moves downward, it drives the connecting rod 12 to move downward. When the connecting rod 12 moves downward, it pushes the drive block 13 to slide inside the slide groove 7. When the drive block 13 slides, it drives the vertical plate 15 and the cutting blade 16 to move, so that the cutting blade 16 can be inserted into the plastic bottle to be cut. Then, the motor 5 is started to drive the auxiliary plate 6 to rotate, which in turn drives the L-shaped frame 8 and the cutting blade 16 to rotate. When the cutting blade 16 rotates, it cuts the plastic bottle, thereby cutting plastic bottles of different diameters.

[0023] As a technical optimization of this utility model, the centering component includes two fixed plates 18 fixedly connected to the upper end of the conveyor 1. Each of the two fixed plates 18 has a first electric push rod 19 installed on its opposite side.

[0030] In this embodiment, the slider 11 is sleeved on the outer wall of the limiting rod 10 and slidably connected to the limiting rod 10. The limiting rod 10 can conveniently limit the slider 11 and prevent the slider 11 from rotating axially.

[0031] As a technical optimization of this utility model, the upper end faces of the two half gears 21 are connected to auxiliary rods 17 through and fixedly connected, and the lower end faces of the two auxiliary rods 17 are movably connected to the conveyor 1.

[0032] In this embodiment, the two half gears 21 can be easily supported by two auxiliary rods 17.

[0033] Working principle: In use, the plastic bottle to be cut is first centered by the centering component. Then, the second motor 24 is started to drive the lead screw 9 to rotate. When the lead screw 9 rotates, it drives the slider 11 to move downward. When the slider 11 moves downward, it drives the connecting rod 12 to move downward. When the connecting rod 12 moves downward, it pushes the drive block 13 to slide inside the slide groove 7. When the drive block 13 slides, it drives the vertical plate 15 and the cutting blade 16 to move, so that the cutting blade 16 can be inserted into the plastic bottle to be cut. Then, the motor 5 is started to drive the auxiliary plate 6 to rotate, which in turn drives the L-shaped frame 8 and the cutting blade 16 to rotate. When the cutting blade 16 rotates, it cuts the plastic bottle, thereby cutting plastic bottles of different diameters.
