A scrap recycling device for the production process of plastic parts

Abstract

The present invention belongs to the technical field of plastic recycling and processing, and discloses a scrap recycling device for a plastic parts production process, including a spraying component. The present invention sets the coordination of structures such as the spraying component and the cleaning component. Since the polygonal tube is polygonal, the spraying mechanism is forced to spray water only when it is facing the baffle plate three, and the water pressure generated by it will push the baffle plate three to fold and allow the scraps to enter the polygonal tube. In addition, the plastic scraps will be cleaned of dirt and dust on them by the water pressure. When the spraying mechanism is no longer facing the baffle plate three, the spring sheet two forces the baffle plate three to return to the original position and prevents the remaining scraps from entering the interior of the polygonal tube, and the guide plate continues to rotate, so that the plastic scraps inside the polygonal tube can be cleaned again. Repeating the above work process can make the plastic scraps be cleaned in small quantities and multiple times, thereby improving the efficiency of the device in cleaning the plastic scraps.

Description

Technical Field

[0001] The invention belongs to the technical field of plastic recycling and processing, in particular to a device for recycling scraps in a plastic parts production process. Background Art

[0002] Plastic parts are widely used in modern industry. They can be used in technical fields such as electronic appliances, automobiles, and communication equipment. Plastic parts can be processed or cut into shape more quickly, and can also be designed into more complex structures with a higher degree of freedom. In the process of injection molding or blow molding of plastic parts, according to the manufacturing process requirements, the mold needs to reserve a certain margin. In order to achieve the required precision of the product, the excess part will be cut off and trimmed later, thereby producing scraps.

[0003] Plastic scraps are generally recycled and reused to avoid wasting materials. In the process of parts production and processing, it is inevitable that they will be contaminated with dust or metal filings. In order to improve the recycling quality, they need to be cleaned. Most manufacturers use mixers to clean them, but the scraps are generally small in size, which will cause some plastic scraps to be unable to be cleaned, thereby increasing the subsequent cleaning time.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] The present invention cooperates with structures such as a spraying component and a cleaning component. Since the polygonal tube is polygonal, the water pressure generated by the spray mechanism will push the baffle three to fold and allow the scraps to enter the polygonal tube only when the spray mechanism sprays water directly toward the baffle three. In addition, the plastic scraps will be cleaned of dirt and dust by the water pressure. When the spray mechanism is no longer directly toward the baffle three, the spring sheet two forces the baffle three to return to the original position and prevents the remaining scraps from entering the interior of the polygonal tube.

[0026] The present invention cooperates with structures such as a cleaning component and a cutting component. Under the guidance of the inclined baffle plate three, the plastic scraps will rise and enter the interior of the barrier box, and then move toward the upper chamber. The blade one and the blade two rotate with each other, thereby cutting the plastic scraps inside the barrier box into volumes of almost the same size, thereby facilitating subsequent cleaning and processing work. Similarly, this enables the device to clean plastic scraps of different specifications, thereby improving the applicability of the device.

[0027] The present invention cooperates with structures such as a reflux component and a spray component. During the rotation of the turbine, the plastic scraps in the upper chamber will be extracted through water pipe one, and the impeller will be driven to rotate at the same time. After the plastic scraps enter the interior of water pipe one, they will contact the impeller, and through the rotation of the impeller, they can return to the interior of the first inner cavity through slot three, and continue to spray and clean the interior of shell two through slot one. The water extracted by the turbine through water pipe one eventually flows to the upper chamber through water pipe two, and the end face of water pipe two faces the end face of water pipe one, which enables the plastic scraps at the upper end to quickly enter the interior of water pipe one and perform reflux work, thereby improving the cleaning performance of the device.

DETAILED DESCRIPTION

[0037] 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.

[0038] like Figures 1 to 8As shown, the present invention provides a scrap material recovery device for a plastic parts production process, comprising a spraying assembly 1;

[0039] The spray assembly 1 comprises a housing 11, a housing 12 is movably mounted inside the housing 11, and a plurality of spray mechanisms 13 are arranged at equal angles in the annular direction between the housing 11 and the housing 12;

[0040] Also includes;

[0041] A splitting assembly 7 fixedly mounted on the top of the second housing 12, the splitting assembly 7 is used to inject water and scraps of plastic parts;

[0042] A discharge pipe 2 connected to the bottom of the housing 11, the discharge pipe 2 is used to discharge water and scraps of plastic parts;

[0043] A cleaning assembly 6 movably mounted inside the second housing 12;

[0044] The cleaning assembly 6 includes a polygonal tube 61 movably mounted inside the second housing 12, a plurality of guide assemblies 62 are arranged at equal angles around the outer periphery of the polygonal tube 61, a guide plate 63 is movably mounted inside the guide assembly 62, and the polygonal tube 61 is fixed to the bottom of the dividing assembly 7;

[0045] The flow guide assembly 62 includes a baffle plate 3 621 hinged to the inner wall of the polygonal tube 61. The side of the baffle plate 3 621 supports the inner wall of the polygonal tube 61 through a spring sheet 2 623. A limit rod 622 is fixedly installed on the side of the polygonal tube 61.

[0046] The spray mechanism 13 guides the water flow to push the scraps to the side of the baffle plate 3 621;

[0047] A power assembly 3 fixed to the bottom of the housing 1 11, the power assembly 3 is used to drive the guide vane 63 and the housing 2 12 to rotate;

[0048] A reflux assembly 5 is fixedly mounted on the outer periphery of the shell 11.

[0049] The above scheme is adopted: firstly, water and plastic scraps are put into the interior of the second shell 12 through the dividing component 7, and then the power component 3 is started to drive the second shell 12 and the guide plate 63 to rotate. At this time, the second shell 12 and the first shell 11 are in a relative motion state, and the water between the second shell 12 and the first shell 11 will be sprayed toward the outer periphery of the polygonal tube 61 through the spray mechanism 13, so that the plastic scraps inside the second shell 12 contact the third baffle 621. Since the spray mechanism 13 rotates simultaneously with the second shell 12 and the polygonal tube 61 is polygonal, the spray mechanism 13 is forced to spray water only when it is facing the third baffle 621. The water pressure generated by the spray mechanism 13 will push the third baffle 621 to fold. In addition, the plastic scraps will be cleaned of dirt and dust on them by the water pressure;

[0050] At the same time, the plastic scraps will enter the interior of the polygonal tube 61 through the gap between the baffle plate 3 621 and the polygonal tube 61. When the injection mechanism 13 is no longer facing the baffle plate 3 621, the spring plate 2 623 forces the baffle plate 3 621 to return to the original position and prevents the plastic scraps from entering the interior of the polygonal tube 61. The guide plate 63 continues to rotate, and the plastic scraps inside the polygonal tube 61 can be cleaned again. Repeating the above working process can make the plastic scraps be cleaned in small quantities and multiple times, thereby improving the efficiency of the device in cleaning the plastic scraps.

[0051] Since the spring sheet 2 623 forces the baffle 3 621 not to be folded to a horizontal state, and the polygonal tube 61 is blocked by the guide sheet 63, the plastic scraps impacted by the water pressure will not float outward after entering the polygonal tube 61, but will collide with each other inside the polygonal tube 61, further improving the quality of the device for cleaning plastic scraps.

[0052] like Figure 2-Figure 4 As shown, the injection mechanism 13 includes a baffle 131 fixed to the outer periphery of the shell 12, a baffle 132 is hinged to the inner wall of the shell 11, and the middle part of the baffle 132 is elastically hinged to the inner wall of the shell 11 through a spring sheet 133. The shell 12 is provided with a plurality of slots 1341 and slots 1342 equidistantly on both sides of the baffle 131, and a first inner cavity 135 is formed between the baffle 131 and the baffle 132.

[0053] like Figure 1 , Figure 2 , Figure 4 and Figure 8 As shown, the power assembly 3 includes a motor 31 fixedly mounted on the bottom of the housing 11, the output shaft of the motor 31 passes through the bottom of the housing 11 and is transmission-connected to a sun gear 33, a planetary gear 34 is mounted on the internal bearing of the housing 11, and a gear ring 35 is fixedly mounted inside the housing 2 12.

[0054] The sun gear 33 is transmission-connected to the ring gear 35 via the planetary gears 34 , and the top of the sun gear 33 is fixedly connected to the guide vane 63 .

[0055] The above scheme is adopted: the motor 31 drives the ring gear 35 and the shell 2 12 to rotate through the sun gear 33 and the planetary gears 34. At this time, the motor 31 also drives the guide vane 63 to rotate through the sun gear 33, which makes there is a speed difference between the guide vane 63 and the shell 2 12, and the dividing component 7 forces the polygonal tube 61 to be in a fixed state, thereby forcing the injection mechanism 13 to increase the number of times the plastic scraps hit the polygonal tube 61 through the water flow, and during the rotation of the guide vane 63, the plastic scraps can also be stirred and cleaned, further improving the working efficiency of the device.

[0056] With the above solution, when the second housing 12 rotates, the distance between the first baffle 131 and the second baffle 132 is shortened, thereby squeezing the first inner cavity 135, so that the water inside the first inner cavity is sprayed toward the outer periphery of the polygonal tube 61 through the first notch 1341, thereby achieving the purpose of impacting and cleaning the plastic scraps, and at the same time forcing the cleaning component 6 to enter the working state;

[0057] During the process of water jetting from the first slot 1341 , the volume of the adjacent first inner cavity 135 will increase, thereby extracting water from the second housing 12 through the second slot 1342 ;

[0058] When the first inner cavity 135 passes over the second baffle plate 132, the spring sheet 133 forces the second baffle plate 132 to return to the original position and continue to form the first inner cavity 135, and the adjacent baffle plate 131 continues to squeeze the first inner cavity 135, so that the water inside it continues to spray through the slot 1341, thereby improving the smoothness of the device operation, and the water flow can continuously impact the plastic scraps, thereby improving the cleaning efficiency of the device.

[0059] like Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, the dividing assembly 7 includes a diverter plate 71 fixed on the top of the shell 12, a blade 74 is fixedly installed at an equal angle in an annular direction on the top of the diverter plate 71, a threaded cover 73 is threadedly connected to the top of the diverter plate 71, a blocking box 72 is fixedly installed inside the shell 11, and a blade 75 is fixedly installed at an equal angle in an annular direction on the bottom of the blocking box 72.

[0060] The diverter plate 71 divides the interior of the shell 11 into two independent upper and lower chambers. The interior of the polygonal tube 61 is connected to the upper chamber through the blocking box 72. The polygonal tube 61 is fixedly connected to the blocking box 72. The blade 1 74 and the blade 2 75 are staggered.

[0061] The above scheme is adopted: the plastic scraps will rise after being guided by the inclined baffle three 621 and enter the interior of the barrier box 72, and then move toward the upper chamber, but the diverter plate 71 is driven to rotate by the shell two 12, and the barrier box 72 is fixedly installed inside the shell one 11, which makes the blade one 74 and the blade two 75 rotate relative to each other, thereby cutting the plastic scraps inside the barrier box 72 into volumes of almost the same, thereby facilitating subsequent cleaning and processing work. Similarly, this enables the device to clean plastic scraps of different specifications, thereby improving the applicability of the device.

[0062] like Figure 2-Figure 5 As shown, a plurality of wavy metal strips are fixedly mounted at equal intervals on the side of the baffle plate 3 621 , the limit rod 622 limits the flipping angle of the baffle plate 3 621 , and the guide plate 63 is spiral.

[0063] With the above solution, when the water flow hits the plastic scraps, they collide with each other along the track of the metal strips instead of smoothly entering the interior of the polygonal tube 61, thereby increasing the efficiency of the device in cleaning dust and dirt on the plastic scraps. Figure 5 As shown in the limit rod 622, when the water flow impacts the baffle plate 3 621 and folds, the limit rod 622 prevents the baffle plate 3 621 from touching the edge of the guide plate 63, thereby preventing the guide plate 63 from being damaged and affecting the service life of the device, and further extending the subsequent maintenance cycle of the device;

[0064] It should also be noted that the guide plate 63 is spiral-shaped, so that the plastic scraps will rise under the impact of the water flow and enter the interior of the cutting component 7, so that the cutting component 7 can cut the plastic scraps into volumes of similar size, thereby facilitating subsequent cleaning and processing.

[0065] like Figure 1-Figure 4 and Figure 7 As shown, the reflux assembly 5 includes a water pipe 51 fixedly mounted on the side of the shell 11, the internal bearing of the water pipe 51 is equipped with an impeller 52, the interior of the water pipe 51 is fixedly equipped with a filter plate 57, the water pipe 51 is connected to the first inner cavity 135 through a slot 3 53, the internal bearing of the water pipe 51 is equipped with a support shaft 55, the end of the support shaft 55 is fixedly connected to a turbine 56, and the output shaft of the motor 31 is transmission-connected to the support shaft 55 through a chain 32.

[0066] The interior of water pipe 1 51 is connected to the upper end chamber, and the power component 3 also includes water pipe 2 54 connected to the interior of water pipe 1 51. The connection between water pipe 2 54 and water pipe 1 51 is located at the lower end of the turbine 56, and the other end of water pipe 2 54 is connected to the upper end chamber.

[0067] With the above solution, the motor 31 drives the support shaft 55 and the turbine 56 to rotate through the chain 32, and because the diameter of the output shaft of the motor 31 is greater than the diameter of the support shaft 55, the rotation speed of the support shaft 55 increases, thereby increasing the suction force generated by the rotation of the turbine 56;

[0068] During the rotation of the turbine 56, the plastic scraps in the upper chamber will be extracted through the water pipe 1 51, and the impeller 52 will be driven to rotate at the same time. After the plastic scraps enter the water pipe 1 51, they will contact the impeller 52, and after the rotation of the impeller 52, they can return to the first inner chamber 135 through the slot 3 53, and continue to spray and clean the inside of the shell 2 12 through the slot 1 1341, and the filter plate 57 will also prevent the plastic scraps from touching the turbine 56;

[0069] At the same time, it should be noted that Figure 4 as well as Figure 7 As shown in the water pipe 2 54, the water drawn by the turbine 56 through the water pipe 1 51 eventually flows to the upper end chamber through the water pipe 2 54, and the end face of the water pipe 2 54 faces the end face of the water pipe 1 51, which enables the plastic scraps at the upper end to quickly enter the interior of the water pipe 1 51 and perform reflux work, thereby improving the cleaning performance of the device.

[0070] The working principle and use process of the present invention:

[0071] First, water and plastic scraps are placed into the interior of the second housing 12 through the dividing assembly 7, and then the power assembly 3 is started;

[0072] The motor 31 drives the gear ring 35 and the second housing 12 to rotate through the sun gear 33 and the planetary gear 34. At this time, the motor 31 also drives the guide vane 63 to rotate, which causes a speed difference between the guide vane 63 and the second housing 12. During the rotation of the guide vane 63, it drives the second housing 12 and the guide vane 63 to rotate. At this time, the second housing 12 and the first housing 11 are in a relative motion state, and the water between the second housing 12 and the first housing 11 will be sprayed toward the periphery of the polygonal tube 61 through the spray mechanism 13, so that the plastic scraps inside the second housing 12 contact the third baffle 621. Since the spray mechanism 13 rotates simultaneously with the second housing 12 and the polygonal tube 61 is polygonal, the spray mechanism 13 is forced to spray water only when it is facing the third baffle 621. The water pressure generated by it will push the third baffle 621 to fold;

[0073] The plastic scraps will enter the interior of the polygonal tube 61 through the gap between the baffle plate 3 621 and the polygonal tube 61. When the spray mechanism 13 is no longer facing the baffle plate 3 621, the spring plate 2 623 forces the baffle plate 3 621 to return to the original position and prevents the plastic scraps from entering the interior of the polygonal tube 61. The guide plate 63 continues to rotate, and the plastic scraps inside the polygonal tube 61 can be cleaned again.

[0074] Guided by the inclined baffle plate 3 621, the plastic scraps will rise and enter the interior of the blocking box 72, and then move toward the upper chamber, and the blade 1 74 and the blade 2 75 rotate with each other, thereby cutting the plastic scraps inside the blocking box 72 into almost the same volume;

[0075] During the rotation of the turbine 56, the plastic scraps in the upper chamber will be extracted through the water pipe 1 51, and at the same time, the impeller 52 will be driven to rotate. After the plastic scraps enter the water pipe 1 51, they will contact the impeller 52. After the rotation of the impeller 52, they can return to the first inner cavity 135 through the slot 3 53, and continue to spray and clean the inside of the shell 2 12 through the slot 1 1341.
