Description

Technical Field

[0001] The utility model relates to a crushing device for waste plastic sheets, in particular to a crushing machine for waste plastic sheets. Background Art

[0002] In the process of plastic sheet production, it is necessary to cut the plastic sheet into the required size according to the requirements of the customer order. In the process of cutting, some scraps will be generated and cannot be used later. In order to save production costs, many plastic sheet manufacturers will use crushing devices to crush these scraps to facilitate subsequent recycling. The existing crushing device mainly performs crushing work through a crushing roller group set in the box. However, because there is generally only one crushing roller group, and in order to ensure the crushing effect, the teeth of the crushing roller group are generally set relatively densely, which will cause the plastic sheet waste to accumulate above the crushing roller group during the actual operation, which will affect the working efficiency of the entire device. And once the accumulation is too much, it will cause the crushing roller group to jam and other phenomena, affecting the overall crushing effect. Therefore, the existing crushing device for recycling plastic sheet waste has the problems of low working efficiency and poor crushing effect during actual use. Utility Model Content

[0003] The purpose of the utility model is to provide a plastic sheet waste crusher, which can not only improve the crushing rate but also has the advantage of good crushing effect.

By utilizing the two crushing operations, it can be ensured that the crushed plastic sheet waste are all small particles, and there will be no large volume of plastic sheet waste. While ensuring the crushing effect, it also reduces the density limit of the teeth on the first crushing roller, thereby avoiding the accumulation of plastic sheet waste on the first crushing roller and improving the crushing work efficiency; by utilizing the teeth on the auxiliary tooth plate to cooperate with the first crushing roller, the crushing area of ​​the plastic sheet waste on the first crushing roller can be increased, thereby increasing the crushing rate.

[0005] In the aforementioned plastic sheet waste crusher, an air cooling pipe is installed on the auxiliary tooth plate, and a plurality of evenly distributed air nozzles are arranged on both side surfaces of the air cooling pipe, and each air nozzle is arranged tilted downward; the air nozzles on the air cooling pipe can be used to cool down the temperature of the first crushing roller and the box body, thereby avoiding deformation due to excessive temperature and extending the service life; and setting the air nozzle in a downward state can avoid the phenomenon of plastic sheet waste blocking the air nozzle, thereby ensuring the cooling effect.

[0006] In the aforementioned plastic sheet waste crusher, a storage hopper is arranged above the feeding port; the storage hopper is used to facilitate feeding while also preventing the operator from inserting his hands into the box body to cause operating accidents, thereby improving the safety of use.

[0007] In the aforementioned plastic sheet waste crusher, slide rails are provided at the positions corresponding to the collection drawers on the two inner sides of the box body; auxiliary parts are provided at the top ends of the two sides of the collection drawer, and slide grooves matching the slide rails are provided on the sides of the auxiliary parts; by providing auxiliary parts to connect the collection drawer and the slide rails, the stability of the structure is improved.

[0008] In the aforementioned plastic sheet waste crusher, the top surface of the auxiliary component is arc-shaped; setting the top surface of the auxiliary component to be arc-shaped can avoid the accumulation of plastic sheet waste on the auxiliary component, thereby facilitating subsequent cleaning work.

[0009] In the aforementioned plastic sheet waste crusher, a handle is provided on the outer side of the collection drawer; a channel for pulling out the collection drawer is provided on the side of the box body at a position corresponding to the collection drawer; the setting of the handle can easily pull out the collection drawer, making it convenient to use.

[0010] Compared with the prior art, the utility model improves the existing plastic sheet waste processing equipment by arranging an inclined guide plate in the box body, a first crushing roller is arranged above one end of the guide plate, and a second crushing roller is arranged below one end, so that when the plastic sheet waste enters the box body through the feeding port, it will first contact with the first crushing roller for the first crushing work; the plastic sheet waste that has completed the first crushing work will be moved to the second crushing roller through the guide plate for the second crushing work, and finally collected in the collecting drawer. By utilizing the two crushing works, it can be ensured that the crushed plastic sheet waste are all small particles, and there will be no large volume of plastic sheet waste. While ensuring the crushing effect, the density of the teeth on the first crushing roller is also reduced. The degree of the plastic sheet waste is limited, thereby avoiding the accumulation of plastic sheet waste on the first crushing roller, and improving the crushing efficiency; by arranging auxiliary tooth plates on both sides of the two first crushing rollers, the teeth on the auxiliary tooth plates cooperate with the first crushing rollers to increase the crushing area of ​​the plastic sheet waste on the first crushing roller, thereby increasing the crushing rate; and the auxiliary tooth plates can also limit the position of the plastic sheets, avoiding the phenomenon of plastic sheet waste directly falling onto the guide plate, thereby ensuring the crushing effect; at the same time, by slidingly installing a collection drawer on the inner bottom surface of the box body, the collection drawer can be used to collect the crushed plastic sheet waste, thereby facilitating the recycling of the crushed plastic sheets inside, which is convenient for use. In addition, the utility model also installs an air cooling pipe on the auxiliary tooth plate, and air nozzles are installed on both sides of the air cooling pipe, and the air nozzle on one side is arranged between the teeth on the auxiliary tooth plate, so that the air nozzle on this side can cool the auxiliary tooth plate and the first crushing roller to avoid the phenomenon that the temperature of the first crushing roller is too high after working for a long time, thereby preventing the plastic sheet waste from sticking to the first crushing roller to a certain extent, slowing down the wear of the first crushing roller and extending the service life; and the air nozzle on the other side can cool the inside of the box to a certain extent, thereby The roller also performs cooling work, thereby further extending the service life; by arranging a storage hopper on the top surface of the feeding port, the storage hopper can be used to facilitate feeding while preventing the operator from inserting his hand into the box body to cause an operation accident, thereby improving the safety of use; by arranging an auxiliary part to connect the collection drawer and the slide rail, the stability of the structure is improved; and by arranging the top surface of the auxiliary part into an arc shape, the accumulation of plastic sheet waste on the auxiliary part can be avoided, thereby facilitating the subsequent cleaning work; by arranging a handle on the collection drawer, it is convenient to pull the collection drawer out of the box body, thereby facilitating use.
