Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of bale threading, in particular to a regenerated waste bale packaging device. BACKGROUND

[0002] Plastic products are life, industrial and other products processed by using plastic as the main raw material. It includes all products of injection molding, blow molding and other processes using plastic as raw material. Plastic is a kind of synthetic high polymer material with plasticity. It forms the three indispensable synthetic materials in daily life with synthetic rubber and synthetic fiber. Specifically, plastic is a material that can be molded into a certain shape under certain temperature and pressure conditions by adding various additives to natural or synthetic resin, and keeps the shape unchanged at room temperature. The waste plastic bottles can be recycled and reused. The recycled plastic bottles have many values, but they occupy a lot of space, so they need to be squeezed and then bundled during transportation.

[0003] In the prior art, waste squeezing and packaging mainly rely on manual operation. After the waste is continuously put into the feeding bin, it is squeezed for many times to form a bale of a predetermined size. Since the quantity and volume of the material cannot be controlled, the length of the bale is not uniform, and manual iron wire threading is required for bundling during subsequent bundling, which is quite cumbersome. Alternatively, a semi-automatic iron wire threading machine is used for manual operation, that is, after finding the appropriate bundling position, the iron wire is threaded and bundled. However, the allowable error range of the bale length is very limited. If it exceeds a certain range, the machine needs to be stopped and a part of the material needs to be removed to thread and bundle the iron wire, which is time-consuming and labor-intensive and affects the efficiency of waste packaging work.

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application will be described clearly and completely below with reference to the drawings. Obviously, the described embodiments are part of the embodiments of the present application, not all.

[0033] As Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown in the present embodiment, a waste material bale packing device is provided, which comprises a feed frame 1 and a pressure material bin 2 connected with the feed frame 1. The feed frame 1 is internally provided with a pressure material assembly for extruding waste material. The pressure material bin 2 is provided on one side with a wire passing assembly for passing iron wire through the bale, and on the other side with a shearing assembly for shearing the iron wire and a wire binding assembly symmetrically arranged on both sides of the shearing assembly for winding the iron wire. The pressure material bin 2 is further provided with a positioning assembly for automatically positioning the wire passing assembly, the shearing assembly and the wire binding assembly to the corresponding position of the pressure material assembly to realize packing of bales of different sizes.

[0034] When it is necessary to extrude and pack the plastic waste, the plastic waste is first put into the feeding frame 1, and then the waste is pressed into the pressing bin 2 by the pressing assembly and extruded into a bale. When the pressing assembly stops, the positioning assembly can automatically position the threading assembly, the shearing assembly and the wire binding assembly to the positions corresponding to the pressing assembly. At this time, the threading assembly will thread the iron wire through the bale, and then the shearing assembly will cut the iron wire threaded through the bale, and then the wire binding assembly will wind the iron wire together to pack the bale. Finally, the pressing bin 2 is opened, and the pressing assembly is started again to push the packed bale out of the pressing bin 2, solving the problem that the packing device in the prior art cannot thread and bind the extruded bales of different sizes, thereby improving the efficiency of extruding and packing the plastic waste.

[0035] As shown in Figure 5 , as a preferred embodiment, on the basis of the above-mentioned mode, further, the pressing assembly comprises an extrusion oil cylinder 3 arranged on the side wall of the feeding frame 1 and a push head 301 arranged at the output end of the extrusion oil cylinder 3.

[0036] Starting the extrusion oil cylinder 3 can push the push head 301 to move towards the inside of the pressing bin 2, at this time, the waste can be extruded into a bale by the push head 301, which is convenient for subsequent binding of the waste formed into a bale.

[0037] As shown in Figure 2 and Figure 11 , as a preferred embodiment, on the basis of the above-mentioned mode, further, the positioning assembly comprises a driving shaft 12 and a driven shaft 13 rotatably arranged on both sides of the top of the pressing bin 2, a third sprocket 1201 arranged at both ends of the driving shaft 12, a fourth sprocket 1301 arranged at both ends of the driven shaft 13, a fifth sprocket 14 arranged on both sides of the first fixed frame 201 and the second fixed frame 202, a pulling chain 18 meshingly wound between the third sprocket 1201, the fourth sprocket 1301 and the two groups of fifth sprockets 14, and a driving mechanism arranged at the top of the pressing bin 2 for driving the pulling chain 18 to transmit back and forth, wherein the two ends of the threading slide plate 4 and the shearing slide plate 7 are respectively connected to the two ends of the pulling chain 18.

[0038] The driving mechanism comprises a reduction motor 11 arranged at the top of the pressing bin 2, a driving sprocket 1101 arranged at the output end of the reduction motor 11, a driven sprocket 1202 arranged on the outer wall of the driving shaft 12, a transmission chain 1102 meshingly wound between the driving sprocket 1101 and the driven sprocket 1202, and an encoder 19 arranged at the top of the pressing bin 2 and connected to the signal of the reduction motor 11.

[0039] When the plastic waste is extruded into a bale, the extrusion oil cylinder 3 stops working, and the push head 301 also stops moving. At this time, the encoder 19 controls the reduction motor 11 to start, which drives the driving shaft 12 to rotate through the transmission chain 1102. The driving shaft 12 drives the pulling chain 18 to move on the third sprocket 1201 and the fourth sprocket 1301. When the reduction motor 11 drives the driving shaft 12 to rotate forward, the pulling chain 18 pulls the wire threading slide plate 4 and the shearing slide plate 7 to move towards the outlet direction of the compression bin 2. When the reduction motor 11 drives the driving shaft 12 to rotate reversely, the pulling chain 18 pulls the wire threading slide plate 4 and the shearing slide plate 7 to move towards the feeding frame 1. Therefore, the encoder 19 automatically controls the reduction motor 11 to rotate forward and reversely, and pulls the wire threading slide plate 4 and the shearing slide plate 7 to move to the stop position of the push head 301 through the pulling chain 18, so as to facilitate the wire threading and bundling of the bale extruded into different sizes.

[0040] The inner walls of the first fixed frame 201 and the second fixed frame 202 are provided with slide plate guide columns 15, and the wire threading slide plate 4 and the shearing slide plate 7 are respectively connected with the slide plate guide columns 15 on the inner walls of the first fixed frame 201 and the second fixed frame 202. When the wire threading slide plate 4 and the shearing slide plate 7 are pulled by the pulling chain 18, they will slide on the slide plate guide columns 15, so as to facilitate the stable movement of the wire threading slide plate 4 and the shearing slide plate 7.

[0041] As shown in Figure 1 , Figure 6 and Figure 7 , as a preferred embodiment, on the basis of the above-mentioned mode, further, the wire threading assembly comprises a first fixed frame 201 arranged on the side wall of the compression bin 2, a wire threading slide plate 4 slidingly arranged inside the first fixed frame 201, a fixed frame 5 arranged on the side wall of the wire threading slide plate 4, a wire threading oil cylinder 6 arranged on the side wall of the fixed frame 5, a push plate 601 arranged on the output end of the wire threading oil cylinder 6, and a plurality of wire threading rods 602 arranged on the side wall of the push plate 601. The side wall of the push head 301 is provided with a slot for the wire threading rod 602 to pass through.

[0042] The inner wall of the wire threading slide plate 4 is provided with a limiting guide column 401, and the push plate 601 is slidingly connected with the limiting guide column 401. The inner wall of the side of the fixed frame 5 away from the wire threading oil cylinder 6 is provided with a plurality of horizontal guide wheels 402 in contact with the rod wall of the wire threading rod 602. One end of the wire threading rod 602 away from the push plate 601 is provided with a wire guide wheel 603.

[0043] When the wire threading slide 4 automatically locates the position corresponding to the push head 301, the wire is placed inside the wire guide wheel 603, and then the wire threading oil cylinder 6 is started to work to push the push plate 601 to move. The push plate 601 will push the wire threading rod 602 to thread the wire through the bale. The horizontal guide wheel 402 can limit the wire threading rod 602, so that the wire threading rod 602 can thread the wire horizontally through the bale. The limiting guide column 401 can ensure that the push plate 601 can be pushed more stably.

[0044] As shown in Figure 8 , Figure 9 and Figure 10 , as a preferred embodiment, on the basis of the above mode, further, the shearing assembly comprises a second fixed frame 202 arranged on the side of the material pressing bin 2 away from the first fixed frame 201, a shearing slide plate 7 slidingly arranged inside the second fixed frame 202, a shearing oil cylinder 8 arranged on the top of the shearing slide plate 7, a movable blade 801 arranged on the output end of the shearing oil cylinder 8, and a fixed blade 802 arranged on the side wall of the shearing slide plate 7 and matched with the movable blade 801.

[0045] When the wire is threaded through the bale, the wire will be squeezed between the movable blade 801 and the fixed blade 802. At this time, the shearing oil cylinder 8 is started to work to push the movable blade 801 to move vertically downward. Through the cooperation of the movable blade 801 and the fixed blade 802, the wire can be cut off.

[0046] As shown in Figure 8 , Figure 9 and Figure 10 , as a preferred embodiment, on the basis of the above mode, further, the wire bundling assembly comprises a hydraulic motor 9 arranged on the top of the material pressing bin 2, a first sprocket 901 arranged on the output end of the hydraulic motor 9, a plurality of groups of second sprockets 902 symmetrically arranged on both sides of the outer surface of the shearing slide plate 7, a wire bundling chain 903 interlacedly engaged and wound between the first sprocket 901 and the plurality of second sprockets 902, a mounting shaft 10 arranged on the end face of the second sprocket 902 and extending to the inside of the shearing slide plate 7, and a winding hook 1001 arranged on the mounting shaft 10.

[0047] After the wire is cut off, the hydraulic motor 9 is started to work to drive the first sprocket 901 connected to the output end to rotate. The first sprocket 901 will drive the wire bundling chain 903 to move on the first sprocket 901 and the plurality of second sprockets 902, and also drive the second sprockets 902 to rotate simultaneously. The second sprocket 902 will drive the winding hook 1001 to rotate through the mounting shaft 10 to hook up and wind the wire, so that the wire can bundle the bale tightly. Then the hydraulic motor 9 is controlled to drive the first sprocket 901 to reverse, and the second sprocket 902 is reversed through the wire bundling chain 903, so that each winding hook 1001 is reversed to release the wire, so that the wire can be included by bundling.

[0048] Wherein, the top of the feeding frame 1 is provided with a feeding hopper 101, the output end of the pressing bin 2 is provided with a lifting oil cylinder 16 on both sides, and the output end of the lifting oil cylinder 16 is provided with a bin door 17 for sealing the output end of the pressing bin 2; when the bale is baled, the lifting oil cylinder 16 is started to work to lift the bin door 17 upward to open the pressing bin 2, and then the extrusion oil cylinder 3 is started to work to push the push head 301, so that the baled bale can be pushed out of the pressing bin 2.

[0049] Specifically, the working principle of the present application is:

[0050] When it is necessary to pack the plastic waste, the waste is first put into the feeding frame 1, the extrusion oil cylinder 3 is started to drive the push head 301 to move to extrude the waste into a bale, at this time the encoder 19 controls the reduction motor 11 to drive the wire passing slide plate 4 and the shearing slide plate 7 to automatically locate to the position corresponding to the push head 301, then the wire passing oil cylinder 6 drives the wire passing rod 602 to move to pass the iron wire through the bale, the shearing oil cylinder 8 continues to work to drive the movable blade 801 to move to cut the iron wire, the hydraulic motor 9 is started to work to drive each group of winding hooks 1001 to rotate to hook and wind the iron wire, then the bale is tightly baled, finally the lifting oil cylinder 16 is started to work to drive the bin door 17 to move upward to open the pressing bin 2, the extrusion oil cylinder 3 is started again to drive the push head 301 to move forward to push the packed bale out of the pressing bin 2, so that the bale extruded into different sizes can be baled, and the working efficiency is improved.
