Description

Technical Field

[0001] This utility model relates to the field of plastic crushing technology, specifically a plastic particle crushing device. Background Technology

[0002] In existing technologies for recycling plastics, crushing the plastic into granules is an essential step.

[0003] In existing technologies, common plastic crushing devices include roller crushers, which crush plastic by biting it with relatively rotating rollers. However, when crushing plastic, especially plastic buckets, the plastic buckets are smooth and cylindrical, and they easily rotate with the rollers after entering the crusher. This prevents the crushing teeth of the rollers from engaging with the plastic bucket, thus affecting the crushing efficiency. Therefore, an improved plastic granulation crushing device is needed to address this problem. Utility Model Content

[0004] The purpose of this invention is to provide a plastic granule crushing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a plastic granule crushing device, comprising a crushing chamber, with crushing rollers movably mounted on both sides of the crushing chamber via bearings, and a feeding mechanism at the upper end of the crushing chamber. The feeding mechanism includes a feeding chamber, a first feeding port, a second feeding port, a chute, a slider, and an extrusion plate. The feeding chamber is fixedly mounted at the upper end of the crushing chamber, with a first feeding port on the surface of the feeding chamber and a second feeding port at the upper end of the feeding chamber. A chute is provided on the surface of the feeding chamber, with a slider movably engaged inside the chute. Extrusion plates are movably mounted on both sides of the feeding chamber, and the extrusion plates are fixedly connected to the slider. A transmission mechanism for driving the slider to move is provided between the crushing rollers and the slider.

[0006] Preferably, the transmission mechanism includes an eccentric wheel and a transmission rod. The eccentric wheel is movably mounted on the surface of the feed hopper via a rotating shaft. The transmission rod is movably mounted on the outer surface of the eccentric wheel via a rotating shaft. The end of the transmission rod near the slider is movably connected to the slider via the rotating shaft. One end of the crushing roller is connected to the eccentric wheel via a synchronous pulley and a synchronous belt, so that when the crushing roller rotates, it can drive the eccentric wheel to rotate as well. The transmission mechanism can drive the eccentric wheel to rotate as the crushing roller rotates, and the transmission rod can drive the extrusion plates to move, so that the extrusion plates move closer together, thus flattening the plastic bucket. The plastic bucket is then gripped by the crushing roller, which facilitates the crushing of the plastic bucket.

[0007] Preferably, an extension platform is fixedly installed on both sides of the surface of the crushing chamber, a speed reducer is installed at the upper end of the extension platform, and an electric motor is installed on one side of the speed reducer. The electric motor and the speed reducer can provide power to the entire equipment.

[0008] Preferably, the power output shaft of the motor is connected to the power input shaft of the reducer via a coupling, and the power output shaft of the reducer is fixedly connected to the crushing roller. The motor can drive the reducer to work, thereby driving the crushing roller to rotate.

[0009] Preferably, a support is provided at the lower end of the crushing chamber, which can provide stable support for the device.

[0010] Preferably, telescopic rods are fixedly installed on both sides inside the feeding hopper, and the movable end of the telescopic rod is fixedly connected to the extrusion plate. The telescopic rods can ensure the stability of the extrusion plate when it moves left and right.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. For plastic products such as plastic buckets, this device can be fed in through the second feed port. After feeding, since the crushing roller and eccentric wheel of this device are linked, the eccentric wheel can be driven to rotate when the crushing roller rotates. In this way, the extrusion plate can be moved through the transmission rod, so that the two extrusion plates intermittently approach each other, thus squeezing the plastic bucket flat. In this way, the plastic bucket is bitten by the crushing roller, which facilitates the crushing of the plastic bucket.

[0013] 2. When this utility model is used, the operation of the extrusion plate is completely linked with the crushing roller, so there is no need for other complex control devices and power devices, which makes it convenient to use, especially suitable for crushing work scenarios with a large number of plastic buckets.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a plastic granule crushing device, including a crushing chamber 1. Crushing rollers 2 are movably arranged on both sides of the crushing chamber 1 via bearings. A feeding mechanism is provided at the upper end of the crushing chamber 1. The feeding mechanism includes a feeding chamber 3, a first feeding port 4, a second feeding port 5, a chute 6, a slider 7, and an extrusion plate 8. The feeding chamber 3 is fixedly arranged at the upper end of the crushing chamber 1. The first feeding port 4 is opened on the surface of the feeding chamber 3. The second feeding port 5 is provided at the upper end of the feeding chamber 3. The chute 6 is opened on the surface of the feeding chamber 3. The slider 7 is movably engaged inside the chute 6. The extrusion plate 8 is movably arranged on both sides of the inside of the feeding chamber 3. The extrusion plate 8 is fixedly connected to the slider 7. A transmission mechanism for driving the slider 7 to move is provided between the crushing rollers 2 and the slider 7.

[0021] The transmission mechanism includes an eccentric wheel 9 and a transmission rod 10. The eccentric wheel 9 is movably mounted on the surface of the feed bin 3 via a rotating shaft. The transmission rod 10 is movably mounted on the outer surface of the eccentric wheel 9 via a rotating shaft. The end of the transmission rod 10 near the slider 7 is movably connected to the slider 7 via a rotating shaft. One end of the crushing roller 2 is connected to the eccentric wheel 9 via a synchronous pulley and a synchronous belt, so that when the crushing roller 2 rotates, it can drive the eccentric wheel 9 to rotate as well. Through the transmission mechanism, the eccentric wheel 9 can rotate as well when the crushing roller 2 rotates. In this way, the transmission rod 10 can drive the extrusion plate 8 to move, so that the extrusion plates 8 move closer to each other, thus squeezing the plastic bucket flat. In this way, the plastic bucket is bitten by the crushing roller 2, which facilitates the crushing of the plastic bucket.

[0022] An extension platform 11 is fixedly installed on both sides of the surface of the crushing chamber 1. A reducer 12 is installed on the upper end of the extension platform 11. An electric motor 13 is installed on one side of the reducer 12. The electric motor 13 and the reducer 12 can provide power to the entire equipment.

[0023] The power output shaft of the motor 13 is connected to the power input shaft of the reducer 12 via a coupling. The power output shaft of the reducer 12 is fixedly connected to the crushing roller 2. The motor 13 can drive the reducer 12 to work, thereby driving the crushing roller 2 to rotate.

[0024] The lower end of the crushing chamber 1 is provided with a support 14, which can provide stable support for the device.

[0025] Telescopic rods 15 are fixedly installed on both sides inside the feed hopper 3. The movable end of the telescopic rod 15 is fixedly connected to the extrusion plate 8. The telescopic rod 15 can ensure the stability of the extrusion plate 8 when it moves left and right.

[0026] Working principle: When using this device, the plastic is crushed and recycled by the relatively rotating crushing roller 2. Ordinary plastics can be directly fed into the crushing chamber 1 through the first feed port 4.

[0027] For plastic products such as plastic buckets, this device can feed them in through the second feed port 5. After feeding, since the crushing roller 2 and the eccentric wheel 9 of this device are linked, the eccentric wheel 9 can be driven to rotate when the crushing roller 2 rotates. In this way, the extrusion plate 8 can be moved through the transmission rod 10, so that the two extrusion plates 8 intermittently approach each other, thus squeezing the plastic bucket flat. In this way, the plastic bucket is bitten by the crushing roller 2, which facilitates the crushing of the plastic bucket.

[0028] Furthermore, when this device is in use, the operation of the extrusion plate 8 is completely linked with the crushing roller 2, so there is no need for other complex control devices and power devices, making it convenient to use, especially suitable for crushing work scenarios with a large number of plastic buckets.
