Description

Technical Field

[0001] The invention belongs to the technical field of plastic recycling, and in particular relates to a crushing device with a disinfection function. Background Art

[0002] With the widespread use of printers, the amount of discarded toner cartridges is increasing. The recycling of toner cartridge plastics is of great significance. On the one hand, it can avoid the landfill or incineration of a large number of discarded toner cartridges, reduce environmental pollution and waste of resources. On the other hand, recycling toner cartridge plastics can convert them into renewable resources and put them back into production, alleviating the pressure of shortage of plastic raw materials, promoting resource recycling, and promoting green and sustainable development.

[0003] At present, toner cartridges are usually made of a variety of high-quality plastics, such as polystyrene, polycarbonate, etc. By processing the toner cartridges, these valuable plastic resources can be reintegrated into the production cycle. By recycling the toner cartridges, information leakage can be avoided and the privacy and commercial secrets of users can be protected. When recycling plastics, a crusher is needed to crush the toner cartridges, such as the crusher disclosed in patent announcement number CN114872232A.

[0004] At present, when the toner cartridge is pulverized, it is generally pulverized directly by a pulverizing roller. First of all, there will be a lot of toner left in the toner cartridge. If the toner cartridge is directly pulverized for recycling, special toner cleaning and other treatments will be required afterwards. In this process, the toner may escape, which not only pollutes the environment but may also be inhaled by the human body. Secondly, in addition to the main ingredients such as pigments and resins, the toner also contains some organic pollutants such as additives, and bacteria may grow inside it. If it is not handled, it will affect the recycling and reuse of plastics. Summary of the invention

[0038] The crushing unit 14 is installed inside the base 1 and is used to crush garbage. The crushing unit 14 includes a cavity 141 opened inside the base 1, and the upper cavity wall of the cavity 141 is provided with a primary crushing channel 142 connected to the box body 2, and the primary crushing channel 142 is installed with a primary crushing roller assembly 143, the lower cavity wall of the cavity 141 is provided with a secondary crushing channel 144, and the secondary crushing roller assembly 145 is installed inside the secondary crushing channel 144, the primary crushing roller assembly 143 and the secondary crushing roller assembly 145 are both electrically connected to the controller 3, the primary crushing roller assembly 143 and the secondary crushing roller assembly 145 both include a pair of crushing knife rollers and a driving structure, under the action of the driving structure, the pair of crushing knife rollers on the same side rotate towards each other, so that the toner cartridge can be crushed.

[0039] The crushing trigger assembly 15 includes a partition 151 fixedly installed inside the waste bin 131, and a detection tube 152 is fixedly plugged into the end surface of the partition 151, an infrared detection probe 153 is installed inside the detection tube 152, a normally open electromagnetic valve 154 is installed at the outlet end of the suction pump 134, and a shunt pipe 155 is installed on one side of the outlet end of the suction pump 134 located at the inlet end of the normally open electromagnetic valve 154, and a normally closed electromagnetic valve 156 is installed inside the shunt pipe 155, and an air supply valve 156 is fixedly installed on the side wall of the base 1.

The secondary crushing channel 144 is arranged on the side of the sorting hole 164 away from the sealing cover 161. Through the action of the airflow ejected from the jet cone hole 162, the lighter plastic parts will move to one side with the airflow, so that they can move to the secondary crushing channel 144, while the metal parts, due to their heavier weight, will directly fall through the sorting hole 164.

[0041] The operating principle of the present invention is now described as follows: the controller 3 is connected to the external power supply circuit, and then the controller 3 is started. The controller 3 controls the squeezing roller assembly 42 to work. The squeezing roller assembly 42 can make its two squeezing rollers rotate in opposite directions. Then the toner cartridge to be recycled is placed in the interior of the feed sleeve 41 (the toner cartridge needs to be placed parallel to the squeezing roller of the squeezing roller assembly 42, so that the various parts of the toner cartridge after squeezing and crushing are in strips). Under the action of the opposing friction bite force, the toner cartridge will be squeezed and crushed, and fall into the space between the outer rotating mesh sleeve 6 and the inner rotating mesh sleeve 7 through the feed port 8, and the controller 3 controls the drive motor 105 to work. The drive motor 105 can make the outer rotating mesh sleeve 6 rotate in the opposite direction through the drive shaft 101 and the moving gear 102, and the drive shaft 101 is driven by the belt transmission assembly 104. The inner rotating mesh sleeve 7 can be rotated in the same direction, so the inner rotating mesh sleeve 7 and the outer rotating mesh sleeve 6 rotate in opposite directions. With the support of the strip plate 9 on the broken toner cartridge, the broken toner cartridge can be moved between the inner rotating mesh sleeve 7 and the outer rotating mesh sleeve 6, and the broken parts will not block each other because the inner rotating mesh sleeve 7 and the outer rotating mesh sleeve 6 rotate in opposite directions, so that the ultraviolet rays emitted by the ultraviolet disinfection lamp board 123 and the ultraviolet disinfection lamp tube 122 can irradiate the side walls of various parts of the broken toner cartridge from both inside and outside to ensure sufficient disinfection, and then continue to put in the toner cartridge to be recycled until the number of toner cartridges put in reaches a preset maximum value (the preset maximum value is set by the specifications of the entire device and the specifications of the waste toner cartridges, for example, 20), and then stop putting in the toner cartridges;

[0042] When the controller 3 starts the squeezing roller assembly 42, it also starts the suction pump 134. The suction end of the suction pump 134 can suck in external air through the waste bin 131, the suction port 132 and the air inlet 133. When the external air flows through the interior of the housing 2, the toner remaining on the toner cartridge will be sucked into the waste bin 131 along with the airflow (because the broken toner cartridge is constantly moving under the action of the inner rotating mesh sleeve 7 and the outer rotating mesh sleeve 6, the toner and dust remaining on the side wall will be shaken off), and will be trapped in the waste bin 131 by the filter 135. By adsorbing and collecting the toner and disinfecting the toner cartridge with ultraviolet rays, it is possible to prevent the toner from escaping and the bacteria in the toner cartridge itself from affecting the recycling effect of the toner cartridge plastic parts.

[0043] Among them, when the controller 3 controls the suction air pump 134 to work, it will control the infrared detection probe 153 to work. Since the inhaled airflow contains toner and dust, the dust in the toner box will hinder the infrared rays emitted by the infrared detection probe 153, thereby reducing the infrared ray intensity received by the receiving end of the infrared detection probe 153. At this time, the infrared detection probe 153 will not output an electrical signal to the controller 3. As the toner and dust inside the toner box are gradually removed, the airflow passing through the detection tube 152 is gradually clean. At this time, the infrared ray intensity received by the receiving end of the infrared detection probe 153 is high. After the infrared ray intensity detected by the infrared detection probe 153 exceeds the threshold, the infrared detection probe 153 The head 153 will output an electrical signal to the controller 3. At this time, the controller 3 controls the normally open solenoid valve 154 and the normally closed solenoid valve 156 to work. The normally open solenoid valve 154 is energized to close, and the normally closed solenoid valve 156 is energized to open. Therefore, the airflow output by the suction pump 134 will enter the interior of the air box 157, and part of the air in the air box 157 will be discharged through the air vent 158. If the airflow cleanliness only meets the standard occasionally, the infrared detection probe 153 will output an electrical signal to the controller 3. At this time, the airflow delivered to the interior of the air box 157 is relatively small, and the airflow inside the air box 157 can be discharged in time through the air vent 158. Therefore, the air pressure switch 159 will not be triggered. If there is ink remaining in the toner cartridge, The powder and dust are fully removed, and the air cleanliness continues to meet the standard. At this time, the infrared detection probe 153 will continue to output an electrical signal to the controller 3, so the suction air pump 134 will continue to deliver airflow to the inside of the air box 157. At this time, the air inside the air box 157 cannot be discharged in time only through the air vent 158, so the air pressure inside the air box 157 will gradually increase, so that the moving contact of the air pressure switch 159 is closed, and the air pressure switch 159 will output a closing electrical signal to the controller 3. At this time, the controller 3 will start the crushing work after 5 minutes (if there is a lot of toner and dust inside the toner box, the longer the interval between the time when the air pressure switch 159 is triggered and the time when the controller 3 is started, the higher the pressure. The longer the time of disinfection is, the shorter the time of disinfection is. Since there are more toner and dust, it means that the inside of the toner cartridge is more seriously polluted, so the disinfection time of the toner cartridge is increased. If the controller 3 receives the closing electrical signal of the air pressure switch 159 within the first 10 minutes before the controller 3 is started, the controller 3 will control the entire crushing work to be performed 15 minutes after the controller 3 is started, that is, the disinfection time of the toner cartridge is not less than 15 minutes. Since toner and dust will affect the irradiation of the side wall of the toner cartridge by ultraviolet disinfection, the controller 3 delays the start of the crushing work by 5 minutes after the air pressure switch 159 is closed, which can ensure the adequacy of the disinfection of the toner cartridge);

[0044] After the controller 3 starts the crushing operation, the controller 3 will control the electric push rod 112 to work at a fixed time. At this time, the arc baffle 111 will leave the fixed mesh sleeve 5, so that the discharge port of the fixed mesh sleeve 5 can be opened. At this time, under the rotation of the outer rotating mesh sleeve 6 and the inner rotating mesh sleeve 7, the toner cartridge is gradually discharged through the discharge port and falls into the primary crushing channel 142, and the controller 3 controls the primary crushing roller assembly 143 inside the primary crushing channel 142 to work. The primary crushing roller assembly 143 can perform primary crushing on the toner cartridge (the distance between the two crushing rollers of the primary crushing roller assembly 143 is greater than the distance between the two crushing rollers of the two secondary crushing roller assemblies 145, and the distance between the two crushing rollers of the primary crushing roller assembly 143 is greater than the diameter of the metal shaft of the developing roller inside the toner cartridge, etc., to avoid the crushing roller directly contacting the metal The shaft is squeezed and blocked, resulting in damage to the crushing roller), and the fragments after primary crushing will fall into the cavity 141. After the controller 3 receives the closing electrical signal of the air pressure switch 159, it will control the normally open solenoid valve 154 and the normally closed solenoid valve 156 to continue to keep the power off. At this time, the airflow output by the suction air pump 134 will enter the sealing cover 161 and spray the airflow through each jet cone hole 162. Under the action of the sprayed airflow, the lighter plastic parts will move to the secondary crushing channel 144 with the airflow, while the metal parts will fall directly through the sorting hole 164 due to their own heavy weight, so that the metal parts and plastic parts can be distinguished and discharged, which is convenient for the recycling and reuse of the plastics. When there is no falling material in the secondary crushing channel 144 and the sorting hole 164, the crushing work of this batch of toner cartridges is completed.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
