Description

Technical Field

[0001] The present invention relates to the technical field of cleaning and recycling of plastic or waste materials containing plastic components, and more specifically, to a plastic product cleaning device. Background Art

[0002] Disposable plastic syringes, plastic medicine bottles, plastic infusion bags and plastic packaging of medical devices often encounter the problem of being unable to clean the inside of the bottle during the cleaning and recycling process. Since these plastic products have a closed or semi-closed structure, the pollutants remaining inside the bottle cannot be effectively removed when they are squeezed and crushed. In particular, when the bottle has not been completely crushed, it is difficult for the cleaning fluid or disinfectant to penetrate into the interior, resulting in the pathogens and residues inside not being thoroughly treated. This is particularly evident in slender and narrow medical waste plastics such as infusion bags or syringes. Even during high-pressure cleaning or spraying, the external cleaning can be completed relatively effectively, but the interior often forms a cleaning dead corner, which greatly increases the risk of residual pollutants mixing in during the recycling process and reduces the quality and safety of recycled plastics. Summary of the invention

[0003] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides a plastic product cleaning device. Through the design of blade piece one and blade piece two, the cleaning liquid or disinfectant can penetrate into the interior of the bottle body during the crushing, recycling and cleaning process of the plastic product, so as to solve the problems raised in the above-mentioned background technology.

The spherical clamping blocks on both sides of the cutter head member 2 are normally clamped in the inner cavity of the liquid outlet to reduce excessive water leakage and liquid leakage; 3. Under normal conditions, a certain gap is left between the blade piece 2 and the slide slot through the positioning slot; the purpose of this design is to ensure that a portion of the cleaning liquid can still be sprayed onto the surface of the plastic object when the plastic object is not punctured. The existence of this gap makes the cleaning device more flexible and adaptable. When the equipment is in standby mode or does not contact the object to be cleaned, the spraying device can still work continuously and effectively cover the surface of the plastic object, thereby achieving pretreatment. This pre-spraying function not only improves the cleaning efficiency, but also enhances the permeability of the liquid to pollutants, making the subsequent crushing and cleaning process more efficient; 4. A plurality of supporting cross bars are installed on the outer wall of the cutter head seat, wherein the supporting cross bars can be installed on the front of the crushing knife in a fixed or rotatable connection. When the crushing knife is extruding plastic structures of different styles, the supporting cross bars are used to provide different styles of force points to reduce the occurrence of the situation where the plastic structure cannot be clamped.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Refer to the instruction manual Figure 1-9 A plastic product cleaning device according to an embodiment of the present invention comprises a plastic recycling and crushing mechanism 1, a bracket 2 is installed at the bottom of the plastic recycling and crushing mechanism 1, and a plurality of supporting mechanisms 3 are installed at the bottom of the bracket 2, wherein Figure 1 As shown, a conveyor belt for feeding can be placed between the two groups of support mechanisms 3, and the conveyor belt can be made of a waterproof product structure. After the waste passes through the plastic recycling and crushing mechanism 1, it can directly fall on the conveyor belt for cleaning and recycling, thereby improving the efficiency of cleaning and recycling. If there is no conveyor belt, it can also be piled at the bottom of the plastic recycling and crushing mechanism 1. After flushing, secondary transfer or transportation is performed. The plastic recycling and crushing mechanism 1 includes an outer frame 101, and the top and bottom of the outer frame 101 are set in an open shape, and the middle part of the bracket 2 is also set in an open shape. The plastic extruded at the top of the plastic recycling and crushing mechanism 1 falls through the bracket 2, and the outer frame 101 is fixedly installed on the top of the bracket 2. The inner part of the outer frame 101 is installed with a middle shaft 106 through a bearing, wherein the bearing can be selected from a bearing model with good load-bearing capacity. The two ends of the middle shaft 106 are respectively fixedly installed with a water pipe connector 102 and a coupling seat 104, and a motor 105 is installed on one side of the outer frame 101 through bolts, and the output shaft end of the motor 105 is connected to the coupling seat 104; Among them, the middle axis 106 is set in a hollow structure, one end of the middle axis 106 is installed with a water pipe connector 102, one end of the water pipe connector 102 is sealed and rotatably connected to the water pipe connector 2 103, the water pipe connector 2 103 is used to connect the water pipe, and the water pipe connector 102 is rotatably connected to the inside of the outer frame 101 through a bearing; a crushing knife 107 for extrusion and crushing is installed on the outside of the middle axis 106, and a liquid outlet 117 is provided at the end of the crushing knife 107, and the middle axis 106 is connected to the liquid outlet 117; it should be noted that the motor 105 drives the coupling seat 104 and the middle axis 106 to rotate when working, and the two ends of the middle axis 106 are connected to the middle part of the outer frame 101 through bearings to form a rotatable support effect, the purpose is to ensure that the middle axis 106 and the crushing knife 107 can rotate to extrude and crush the plastic, because the water pipe connector 2 103 needs to be connected to a water pipe or other liquid inlet equipment , it is necessary to ensure that the water pipe will not be tangled when the central axis 106 rotates slowly. Therefore, the supporting structure of the water pipe connector 102 and the water pipe connector 2 103 needs to use a quick connector that can be both rotated and sealed. Common rotatable water pipe quick connectors include similar to 246 water pipe quick plug connectors, which have balls and sealing rings inside, and are also commonly used parts in agricultural irrigation. This structure can achieve the effect of rotation and sealing. In actual use, as long as it is ensured that the water pipe will not be tangled, the water pipe connector 2 103 and the water pipe connector 1 102 can use any suitable parts; after the connection is completed, the motor 105 drives the crushing knife 107 to squeeze and crush the plastic material. When the crushing knife 107 is inserted into the plastic structure, the liquid outlet 117 at its end sprays the cleaning or disinfecting liquid into the bottle body through the water pipe connector 2 103, thereby improving the convenience of cleaning and reducing the cleaning dead corners.

[0024] The outer part of the middle axis 106 is sleeved with the middle axis 2 108, and the middle axis 106 and the middle axis 2 108 are in a relatively fixed state during operation. The outer wall of the middle axis 2 108 is fixedly installed with a plurality of cutter head seats 109, and the crushing knife 107 is fixedly connected to the cutter head seat 109; the outer wall of the middle axis 106 is provided with a plurality of slots 110, and the inner wall of the middle axis 2 108 is provided with a plurality of slots 2 111, and the slots 110 and the slots 2 111 are connected, such as Figure 3As shown, slot one 110 and slot two 111 can be in a fixed sealing state or an assembled sealing state. In the assembled sealing state, a relative sealing interface is provided at the contact position of slot one 110 and slot two 111, which is similar to an extruded rubber ring structure. In the process of mutual insertion, a relative sealing effect is achieved by extrusion. An annular groove 112 is provided inside the middle axis 108, and a through groove 113 is provided between the middle axis 108 and the cutter head seat 109. The through groove 113 is connected with the annular groove 112 and the slot two 111. A cavity is provided inside the crushing knife 107, and the cavity of the crushing knife 107 is connected with the through groove 113.

[0025] A cutter head 114 and a cutter head 2 115 are respectively provided at the ends of the crushing knife 107, track grooves 116 are provided on both sides of the cutter head 114, a liquid outlet 117 is provided at the end of the track groove 116, the liquid outlet 117 is communicated with the inner cavity of the crushing knife 107, and spherical clamping blocks for sliding connection in the inner cavity of the track groove 116 are provided on both sides of the cutter head 2 115, and the spherical clamping blocks can be sealed and clamped in the liquid outlet 117 under normal conditions; A sliding slot 118 is provided between the two blade pieces 114. Figure 7 As shown, the sliding slot 118 is opened on one side of the crushing knife 107, the second blade piece 115 is slidably connected to the inner cavity of the sliding slot 118, the top and bottom of the second blade piece 115 are provided with positioning slots 119, the inner wall of the crushing knife 107 is fixedly installed with a positioning plate 120, and a spring member 121 is installed between the positioning plate 120 and the second blade piece 115. Under normal conditions, the spring member 121 pushes the second blade piece 115 to move to the position of the first blade piece 114, and the spherical blocks on both sides of the second blade piece 115 are normally connected to the inner cavity of the liquid outlet 117 to reduce excessive water leakage and liquid leakage. In actual use, in order to ensure the efficiency of recycling and crushing plastics, the end of the blade piece 114 can be as sharp as possible, and the blade piece 115 can also be a flat support structure. When the blade piece 115 and the blade piece 114 squeeze the plastic object at the same time, the blade piece 114 can pierce the plastic object more easily, and the flat support structure of the blade piece 115 is pressed on the surface of the plastic object. At this time, the blade piece 114 is inserted into the plastic object, and the cleaning or disinfecting liquid is sprayed through the liquid outlet 117 to reduce the cleaning dead angle; in addition, Figure 7 As shown, under normal conditions, a certain gap can be left between the blade member 115 and the slide slot 118 through the positioning slot 119. The purpose of this arrangement is that a portion of the liquid can be sprayed onto the surface of the plastic object when it is not punctured; in addition, the spherical clamping block can also reduce the problem of blockage of the liquid outlet 117 during the process of reciprocatingly clamping the liquid outlet 117.

When the crushing knife 107 is extruding plastic structures of different styles, the support cross bar 122 is used to provide different styles of force points to reduce the occurrence of the situation where the plastic structure cannot be clamped.

[0027] The support mechanism 3 includes a support leg 31, and a cleaning spray head 32 is installed on the top of the support leg 31. Figure 1 As shown, one end of the cleaning spray head 32 is used to connect the pipeline for conveying the cleaning liquid, and the other end is used for spraying the cleaning spray head. In addition, the support leg 31 can use an electric telescopic rod or a manual telescopic rod according to actual needs. A support seat 33 is installed on the top of the support leg 31, and the bracket 2 is supported on the top of the support seat 33. The function of the cleaning spray head 32 is to be used for cleaning, and the water pipe is connected to realize cleaning by spraying.

[0028] It should be noted that, in actual use, the plastic products are placed from the top of the plastic recycling and crushing mechanism 1, and then undergo extrusion crushing, internal and external puncture spray cleaning and falling cleaning, thereby completing part of the cleaning and recycling process of the plastic products.
