Description

Technical Field

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

[0002] During the cleaning and recycling process of disposable plastic syringes, plastic medicine bottles, plastic infusion bags, and plastic packaging of medical devices, the problem that the inside of the bottle body cannot be cleaned often occurs; due to the closed or semi-closed structure of these plastic products, when they are extruded and broken, the pollutants remaining inside the bottle body cannot be effectively removed; especially when the bottle body is not completely broken, the cleaning liquid or disinfectant is difficult to penetrate into the inside, resulting in the pathogens and residues inside not being thoroughly treated. This situation is particularly obvious 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 relatively effectively completed, but the inside often forms a cleaning dead angle, which greatly increases the risk of residual pollutants mixing in the recycling process and reduces the quality and safety of recycled plastics.

[0013] The technical effects and advantages of the present invention:

[0014] 1. The innovative design of the crushing cutter, the first cutter head part and the second cutter head part enables the cleaning liquid or disinfectant to penetrate into the inside of the plastic bottle during the crushing process of the plastic product. This design overcomes the phenomenon of easy occurrence of cleaning dead corners, reduces the risk of residual pollutants mixing into the recycled plastic, and improves the quality and safety of the recycled plastic.

[0015] 2. Under normal conditions, the spring part pushes the second cutter head part to move towards the position of the first cutter head part. The spherical clamping blocks on both sides of the second cutter head part are clamped in the inner cavity of the liquid outlet under normal conditions to reduce the phenomenon of excessive water leakage and liquid leakage.

[0016] 3. Under normal conditions, there is a certain gap between the second cutter head part and the sliding slot through the positioning slot; the purpose of this design is to ensure that when the plastic object is not punctured, a part of the cleaning liquid can still be sprayed onto its surface. The existence of this gap makes the cleaning device more flexible and adaptable. When the device is in the standby state or not in contact with the object to be cleaned, the spraying device can still work continuously, effectively covering the surface of the plastic object, so as to achieve pretreatment. This pre-spraying function not only improves the cleaning efficiency but also enhances the penetration of the liquid into the pollutants, making the subsequent crushing and cleaning processes more efficient;

[0017] 4. A plurality of support crossbars are installed on the outer wall of the cutter head seat, and the support crossbars can be installed in a fixed or rotatable connection manner in front of the crushing cutter. When the crushing cutter squeezes plastic structures of different styles, the support crossbars are used to provide force points of different styles, reducing the occurrence of the situation where the plastic structure cannot be clamped.

Detailed implementation manners

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Referring to the attached drawings of the specification Figures 1-9 A plastic product cleaning device according to an embodiment of the present invention includes 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 support mechanisms 3 are installed at the bottom of the bracket 2. As Figure 1 shown, a conveyor belt for material transportation can be placed between the two groups of support mechanisms 3. The conveyor belt can be selected with a waterproof product structure. After the waste materials pass through the plastic recycling and crushing mechanism 1, they can directly fall on the conveyor belt for cleaning and recycling, improving the efficiency of cleaning and recycling. If there is no conveyor belt, they can also be stacked at the bottom of the plastic recycling and crushing mechanism 1. After the flushing is completed, they are transferred or conveyed for the second time. The plastic recycling and crushing mechanism 1 includes an outer frame 101. The top and bottom of the outer frame 101 are open. The middle part of the bracket 2 is also open. The plastic after being extruded at the top of the plastic recycling and crushing mechanism 1 falls through the bracket 2. The outer frame 101 is fixedly installed on the top of the bracket 2. A first central shaft 106 is installed inside the outer frame 101 through a bearing. Among them, a bearing with good load-bearing performance can be selected for use. Water pipe connectors I 102 and coupling seats 104 are fixedly installed at both ends of the first central shaft 106 respectively. A motor 105 is installed on one side of the outer frame 101 through bolts. The end of the output shaft of the motor 105 is connected to the coupling seat 104;

[0030] Among them, the first central axis 106 is arranged in a hollow structure. One end of the first central axis 106 is installed with a first water pipe connector 102. One end of the first water pipe connector 102 is rotatably connected in a sealed manner with a second water pipe connector 103. The second water pipe connector 103 is used to connect a water pipe. The first water pipe connector 102 is rotatably connected inside the outer frame 101 through a bearing; outside the first central axis 106, there is installed a crushing knife 107 for extrusion crushing. The end of the crushing knife 107 is provided with a liquid outlet 117, and the first central axis 106 is communicated with the liquid outlet 117; it should be noted that when the motor 105 works, it drives the coupling seat 104 and the first central axis 106 to rotate. Both ends of the first central axis 106 are connected to the middle part of the outer frame 101 through bearings, forming a rotatable supporting effect. The purpose is to ensure that the first central axis 106 and the crushing knife 107 can rotate to extrude and crush plastics. Since the second water pipe connector 103 needs to connect to a water pipe or other liquid inlet devices, it is necessary to ensure that the water pipe will not be wound when the first central axis 106 rotates slowly. Therefore, for the matching structure of the first water pipe connector 102 and the second water pipe connector 103, a quick connector that can both rotate and be sealed needs to be selected. Common rotatable water pipe quick connectors include those similar to 2 / 4 / 6-inch 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 effects of rotation and sealing. In actual use, as long as it is ensured that the water pipe will not be wound, the second water pipe connector 103 and the first water pipe connector 102 can be selected with any suitable parts for use; after the connection is completed, the motor 105 drives the crushing knife 107 to extrude and crush plastic materials. When the crushing knife 107 is inserted into the plastic structure, the liquid outlet 117 at its end sprays cleaning or disinfecting liquid into the bottle body through the second water pipe connector 103, improving the convenience of cleaning and reducing cleaning dead corners.

[0031] A second central axis 108 is sleeved outside the first central axis 106, and the first central axis 106 and the second central axis 108 are in a relatively fixed state during operation. A plurality of cutter head seats 109 are fixedly installed on the outer wall of the second central axis 108, and the crushing knife 107 is fixedly connected to the cutter head seats 109; a plurality of first slots 110 are opened on the outer wall of the first central axis 106, and a plurality of second slots 111 are opened on the inner wall of the second central axis 108. The first slots 110 are communicated with the second slots 111, such as Figure 3As shown, the slot one 110 and the slot two 111 can be in a fixed sealing state or an assembled sealing state. In the assembled sealing state, opposite sealing mating interfaces are provided at the positions where the slot one 110 and the slot two 111 are in contact, similar to an extrusion-type rubber ring structure. During the process of mutual insertion, a relatively sealed effect is achieved through extrusion. An annular groove 112 is provided inside the middle shaft two 108, and a through groove 113 is provided between the middle shaft two 108 and the cutter head seat 109. The through groove 113 is communicated with the annular groove 112 and the slot two 111. A cavity is provided inside the crushing cutter 107, and the cavity of the crushing cutter 107 is communicated with the through groove 113.

[0032] At the end parts of the crushing cutter 107, a cutter head part one 114 and a cutter head part two 115 are respectively provided. Track grooves 116 are provided on both sides of the cutter head part one 114, and 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 cutter 107. Spherical clamping blocks for slidably connecting to the inner cavity of the track groove 116 are provided on both sides of the cutter head part two 115. Under normal conditions, the spherical clamping blocks can be hermetically clamped in the liquid outlet 117;

[0033] A sliding slot 118 is provided between the two cutter head parts one 114. As Figure 7 shown, the sliding slot 118 is provided on one side of the crushing cutter 107. The cutter head part two 115 is slidably connected to the inner cavity of the sliding slot 118. Positioning grooves 119 are provided at the top and bottom of the cutter head part two 115. A positioning plate 120 is fixedly installed on the inner wall of the crushing cutter 107. A spring member 121 is installed between the positioning plate 120 and the cutter head part two 115. Under normal conditions, the spring member 121 pushes the cutter head part two 115 towards the position of the cutter head part one 114. The spherical clamping blocks on both sides of the cutter head part two 115 are hermetically clamped in the inner cavity of the liquid outlet 117 under normal conditions, so as to reduce the phenomenon of excessive water leakage and liquid leakage. In actual use, in order to ensure the efficiency of recycling and crushing plastics, the end of the cutter head part one 114 can preferably be a sharp cutter head as much as possible, and the cutter head part two 115 can also be a planar support structure. When the cutter head part two 115 and the cutter head part one 114 simultaneously extrude a plastic object, the cutter head part one 114 can more easily puncture the plastic object, and the planar support structure of the cutter head part two 115 presses on the surface of the plastic object. At this time, the cutter head part one 114 is inserted into the plastic object, and a cleaning or disinfecting liquid is sprayed through the liquid outlet 117 to reduce cleaning dead corners; In addition, as Figure 7 shown, a certain gap can be left between the cutter head part two 115 and the sliding slot 118 through the positioning groove 119 under normal conditions. The purpose of such a setting is that a part of the liquid can also be sprayed onto its surface when the plastic object is not punctured; In addition, during the process of the spherical clamping blocks reciprocally clamping the liquid outlet 117, the problem of blockage of the liquid outlet 117 can also be reduced.

[0034] A plurality of support cross bars 122 are installed on the outer wall of the cutter head seat 109, as Figure 6 shown. Among them, the support cross bars 122 can be fixedly or rotatably connected to the front part of the crushing cutter 107. When the crushing cutter 107 extrudes plastic structures of different styles, the support cross bars 122 are used to provide force application points of different styles, reducing the occurrence of the situation where the plastic structure cannot be clamped.

[0035] Among them, the support mechanism 3 includes support legs 31, and a spray head 32 for cleaning is installed at the top of the support legs 31, as Figure 1 shown. One end of the spray head 32 for cleaning is used to connect to the pipeline for conveying the cleaning liquid, and the other end is used as a nozzle for spraying cleaning. In addition, the support legs 31 can be selected as electric telescopic rods or manual telescopic rods according to actual needs. A support seat 33 is installed at the top of the support legs 31, and the bracket 2 is supported on the top of the support seat 33. The effect of the spray head 32 for cleaning is for cleaning, and the water pipe is connected to realize the cleaning method of spraying.

[0036] It should be noted that during actual use, plastic products are placed into the plastic recycling and crushing mechanism 1 from the top, and then through extrusion and crushing, internal and external puncture spraying cleaning, and falling cleaning, some processes of cleaning and recycling of plastic products can be completed.

[0037] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
