Description

Technical Field

[0001] This application relates to the field of plastics processing technology, and in particular to support and stabilization devices and recycling material conveying systems. Background Technology

[0002] In the processing of plastics and their products, one of the steps is to transport the parts from a low point to a high point, and during this transportation process, the materials are screened and metal impurities are removed.

[0003] A common conveying method in this process is screw conveying. As the screw rotates, it transports the material from a lower point to a higher point. A pipeline is installed around the screw, thus confining the material within the pipeline as it spirals upwards. Furthermore, a metal rejector can be installed during the screw conveying process to remove metal impurities from the material.

[0004] In this spiral conveying method, the bottom and top ends of the pipeline are fixed to corresponding mechanisms, but the middle of the pipeline is not fixed. If the pipeline is long or even excessively long, vibration may occur during processing, affecting conveying efficiency and quality. If the vibration is too great, it may even affect the structural stability of the spiral. Summary of the Invention

[0005] Based on this, the purpose of this application is to provide a support and stabilization device and a material recycling system, which has the advantage of ensuring the stability of the screw conveying process.

[0006] One aspect of this application provides a support and stabilization device, including a fastening bottom ring, a sleeved outer ring, and a support mechanism; the sleeved outer ring is sleeved on the fastening bottom ring, and the support mechanism is vertically arranged with its top end connected to the sleeved outer ring;

[0007] The fastening bottom ring includes a first bottom half-ring and a second bottom half-ring;

[0008] The first bottom half ring includes a first stepped ring, a first inner ring, and a first bottom ring connecting lug; the first stepped ring is connected to the first inner ring to form a stepped surface, and the first bottom ring connecting lug is fixed at both ends of the first stepped ring respectively;

[0009] The second bottom half-ring includes a second stepped ring, a second inner ring, a second bottom ring connecting lug, a wedge, and a thrust spring; the second stepped ring is connected to the second inner ring to form a stepped surface, and the second bottom ring connecting lug is fixed to both ends of the second stepped ring; a groove is formed on the second stepped ring, one end of the thrust spring is fixed to the bottom surface of the groove, and the other end is fixed to the wedge; the wedge is movably attached to the outer surface of the second inner ring, and the wedge can move along the outer surface of the second inner ring under the drive of the thrust spring;

[0010] When the first stepped ring and the second stepped ring are closed together, the first bottom ring connecting lug and the second bottom ring connecting lug are fitted together and fastened together by bolts.

[0011] The first inner ring and the second inner ring form an inner ring; the first stepped ring and the second stepped ring form a stepped ring;

[0012] The outer sleeve is fitted onto the inner sleeve, and the outer diameter of the stepped ring is larger than the inner diameter of the outer sleeve, such that one end face of the outer sleeve abuts against one end face of the stepped ring.

[0013] The support and stabilizing device described in this application, by setting a fastening bottom ring and a sleeved outer ring, allows the sleeved outer ring and the fastening bottom ring to be detached from each other, thus enabling separation. The support mechanism is then securely installed with the sleeved outer ring, thereby supporting and tightening the sleeved outer ring. Therefore, the assembly of the fastening bottom ring and the sleeved outer ring in this application has two states: one is a relatively tight fit, and the other is a relatively loose separation. When the two are tightly assembled, the pipe fitted inside the fastening bottom ring is securely supported; when they are relatively loose, disassembly and relocation are facilitated.

[0014] Furthermore, the fastening bottom ring of this application includes two half-rings, which are connected by a first bottom ring connecting lug and fastened with bolts. The stepped surface ensures that when the outer sleeve is fitted onto the fastening bottom ring, it is abutted and blocked in the axial direction, thus limiting its travel. The wedge and thrust spring are provided to improve the tightness of the fit between the outer sleeve and the fastening bottom ring. The cooperation of the wedge and thrust spring allows the wedge to move along the axial direction of the fastening bottom ring, thus sealing the gap between the fastening bottom ring and the outer sleeve. Since the position of the wedge is adjustable, the contacting position of the wedge varies depending on the gap. Furthermore, the thrust spring allows for the presence or absence of a wedge between the fastening bottom ring and the outer sleeve.

[0015] Furthermore, a first electromagnet is installed on one end face of the first stepped ring, and a second electromagnet is installed on the end face of the outer sleeve that abuts against the end face of the first stepped ring; such that the first electromagnet and the second electromagnet are arranged facing each other.

[0016] When the first electromagnet and the second electromagnet are energized, their opposite magnetic poles are opposite, causing them to be magnetically attracted to each other.

[0017] Furthermore, the outer ring includes a first outer half-ring, a second outer half-ring, and an outer ring connecting lug;

[0018] The first outer half ring is fixed with outer ring connecting ears at both ends, and the second outer half ring is fixed with outer ring connecting ears at both ends; the first outer half ring and the second outer half ring are connected by the outer ring connecting ears and fastened with bolts.

[0019] Furthermore, the inner diameter of the outer sleeve is larger than the outer diameter of the inner ring, and the difference is 1-6 mm.

[0020] Furthermore, the support mechanism includes a connecting sleeve, a supporting cylinder, and a base; the connecting sleeve is sleeved on the two outer ring connecting lugs on the same side and fastened with bolts;

[0021] The supporting cylinder is vertically arranged, with its top end fixed to the connecting sleeve and its bottom end connected to the base.

[0022] Furthermore, the base includes an upper cylinder, a short-stroke elastic element, a lower cylinder, and a square column;

[0023] The upper cylinder, the lower cylinder, and the supporting cylinder are arranged on the same axis;

[0024] The upper cylinder is fixed to the bottom end of the supporting cylinder. A plurality of short-stroke elastic elements are evenly distributed between the upper cylinder and the lower cylinder, and the upper cylinder is connected to the lower cylinder through the short-stroke elastic elements. The square column is fixedly provided on the lower surface of the lower cylinder.

[0025] The square column is hollow inside.

[0026] Furthermore, the base also includes support legs, a square platform, a square sleeve, and locking bolts;

[0027] The bottom surface of the square tabletop is evenly distributed with multiple supporting legs;

[0028] The square sleeve is fixedly installed at the center of the square tabletop, and a square hole of the same size as the inner hole of the square sleeve is opened at its center.

[0029] The square column is fitted inside the square sleeve and passes through the square hole;

[0030] The side wall of the square sleeve is provided with a bolt connection hole, and the locking bolt is threaded into the bolt connection hole to lock the square column.

[0031] Furthermore, the short-range elastic element is a short spring;

[0032] Multiple short springs have equal length, equal pitch, and equal outer diameter.

[0033] This application also provides a recycling material conveying system, including a feeding mechanism and a support and stabilizing device as described in any of the above embodiments;

[0034] The conveying steel pipe of the feeding mechanism is set at an angle, and the fastening bottom ring is fastened and sleeved on the conveying steel pipe;

[0035] The support mechanism is placed vertically and is inclined relative to the end face of the fastening bottom ring.

[0036] Furthermore, the bottom surface of the feeding mechanism is flush with the bottom surface of the supporting mechanism.

[0046] In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0047] Please see Figures 1-8 This application exemplifies a support and stabilization device, which includes a fastening bottom ring 20, a sleeved outer ring 30, and a support mechanism; the sleeved outer ring 30 is sleeved on the fastening bottom ring 20, and the support mechanism is vertically arranged with its top end connected to the sleeved outer ring 30.

[0048] The fastening bottom ring 20 includes a first bottom half ring 21 and a second bottom half ring 22;

[0049] The first bottom half ring 21 includes a first stepped ring 211, a first inner ring 212, and a first bottom ring connecting ear 213; the first stepped ring 211 is connected to the first inner ring 212 to form a stepped surface A, and the first bottom ring connecting ear 213 is fixed at both ends of the first stepped ring 211 respectively;

[0050] The second bottom half-ring 22 includes a second stepped ring 221, a second inner ring 222, a second bottom ring connecting lug 223, a wedge block 23, and a thrust spring (not shown); the second stepped ring 221 is connected to the second inner ring 222 to form a stepped surface (refer to the stepped surface A of the first bottom half-ring 21), and the second bottom ring connecting lug 223 is fixed to both ends of the second stepped ring 221; a groove is provided on the second stepped ring 221, one end of the thrust spring is fixed to the bottom surface of the groove, and the other end is fixed to the wedge block 23; the wedge block 23 is movably attached to the outer surface of the second inner ring 222, and the wedge block 23 can move along the outer surface of the second inner ring 222 under the drive of the thrust spring;

[0051] When the first stepped ring 211 and the second stepped ring 221 are enclosed, the first bottom ring connecting ear 213 and the second bottom ring connecting ear 223 are fitted together and fastened together by bolts.

[0052] The first inner ring 212 and the second inner ring 222 form an inner ring; the first stepped ring 211 and the second stepped ring 221 form a stepped ring;

[0053] The outer sleeve 30 is sleeved on the inner ring, and the outer diameter of the stepped ring is larger than the inner diameter of the outer sleeve 30, so that one end face of the outer sleeve 30 abuts against one end face of the stepped ring.

[0054] The support and stabilizing device described in this application, by setting a fastening bottom ring 20 and a sleeved outer ring 30, allows the sleeved outer ring 30 to be detached from the fastening bottom ring 20, thus enabling separation. The support mechanism is then securely installed with the sleeved outer ring 30, thereby supporting and tightening the sleeved outer ring 30. Therefore, the assembly of the fastening bottom ring 20 and the sleeved outer ring 30 in this application has two states: one is a tight, relatively fitted connection, and the other is a relatively loose separation. When the two are tightly assembled, the pipe fitted inside the fastening bottom ring 20 is securely supported; when they are relatively loose, disassembly and relocation are facilitated.

[0055] Furthermore, the fastening bottom ring 20 of this application includes two half-rings, which are connected by a first bottom ring connecting lug 213 and fastened with bolts. The stepped surface ensures that when the outer sleeve 30 is fitted onto the fastening bottom ring 20, the outer sleeve 30 is abutted and blocked in the axial direction, thus limiting its travel. The wedge block 23 and thrust spring are provided to improve the tightness of the fit between the outer sleeve 30 and the fastening bottom ring 20. The cooperation between the wedge block 23 and the thrust spring allows the wedge block 23 to move along the axial direction of the fastening bottom ring 20, thus sealing the gap between the fastening bottom ring 20 and the outer sleeve 30. Since the position of the wedge block 23 is adjustable, the position of the contacting wedge block 23 varies depending on the gap. Furthermore, the thrust spring allows the fastening bottom ring 20 and the outer sleeve 30 to be either fitted with or without the wedge block 23.

[0056] It should be noted that the setting of the wedge 23 is particularly important and crucial in this application, and the placement of the wedge 23 is also very important.

[0057] In some preferred embodiments, the inner diameter of the outer sleeve 30 is larger than the outer diameter of the inner ring, with a difference of 1-6 mm. In other words, the inner diameter of the outer sleeve 30 is slightly larger than the outer diameter of the inner ring, with the slight increase ranging from 1-6 mm. This allows the outer sleeve 30 to be movably fitted onto the inner ring, creating a circumferential gap due to the difference in diameter. This gap is secured by the wedge 23 to ensure a tight connection.

[0058] In some preferred examples, the first step ring 211 is positioned diagonally below the first inner ring 212, and the second step ring 221 is positioned diagonally below the second inner ring 222.

[0059] In some preferred embodiments, a first electromagnet (not shown) is installed on one end face of the first stepped ring 211, and a second electromagnet (not shown) is installed on the end face of the sleeved outer ring 30 that abuts against the end face of the first stepped ring 211, such that the first electromagnet and the second electromagnet are arranged facing each other.

[0060] When the first electromagnet and the second electromagnet are energized, their opposite magnetic poles are opposite, causing them to be magnetically attracted to each other.

[0061] The opposing magnetic poles of the two electromagnets are opposite, thus generating a magnetic attraction. The two electromagnets are used to facilitate the outer sleeve 30 moving closer to the stepped surface of the bottom fastening ring 20. At the same time, due to the presence of the wedge block 23, the closer the two come together, the tighter their connection becomes, and the more stable the connection between the outer sleeve 30 and the bottom fastening ring 20 becomes.

[0062] In some preferred embodiments, the outer sleeve 30 includes a first outer half-ring 31, a second outer half-ring 32, and an outer ring connecting lug 33;

[0063] The first outer half-ring 31 is fixed with the outer ring connecting ear 33 at both ends, and the second outer half-ring 32 is fixed with the outer ring connecting ear 33 at both ends; the first outer half-ring 31 and the second outer half-ring 32 are connected by the outer ring connecting ear 33 and fastened by bolts.

[0064] The outer ring is designed with two semi-rings, which can be disassembled and opened for easy installation and position adjustment; the connection is made through connecting ears to ensure the tightness and stability of the connection.

[0065] In some preferred embodiments, the support mechanism includes a connecting sleeve 40, a support cylinder 50, and a base; the connecting sleeve 40 is sleeved on the two outer ring connecting ears 33 on the same side and fastened by bolts;

[0066] The supporting cylinder 50 is vertically arranged, with its top end fixed to the connecting sleeve 40 and its bottom end connected to the base.

[0067] The connecting sleeve 40 is used to be fitted onto the two outer ring connecting ears 33 and is fastened to the two outer ring connecting ears 33 by bolts, so that the connection between the connecting sleeve 40 and the fitted outer ring 30 is tight and stable.

[0068] In some further examples, the support cylinder 50 is welded to the connecting sleeve 40, or the support cylinder 50 and the connecting sleeve 40 are integrally formed.

[0069] It is advisable to weld the supporting cylinder 50 to the connecting sleeve 40 for fixation, and the welding should be carried out on site.

[0070] In some preferred embodiments, the base includes an upper cylinder 61, a short-stroke elastic element 62, a lower cylinder 63, and a square column 64;

[0071] The upper cylinder 61, the lower cylinder 63, and the supporting cylinder 50 are arranged on the same axis;

[0072] The upper cylinder 61 is fixed to the bottom end of the supporting cylinder 50. A plurality of short-stroke elastic elements 62 are evenly distributed between the upper cylinder 61 and the lower cylinder 63, and the upper cylinder 61 is connected to the lower cylinder 63 through the short-stroke elastic elements 62. The square column 64 is fixedly provided on the lower surface of the lower cylinder 63.

[0073] The square column 64 is hollow inside, making it a hollow column.

[0074] In some preferred embodiments, the base further includes a support leg 71, a square platform 72, a square sleeve 73, and a locking bolt 74;

[0075] The bottom surface of the square tabletop 72 is evenly distributed with multiple supporting legs 71;

[0076] The square sleeve 73 is fixedly installed at the center of the square tabletop 72, and a square hole of the same size as the inner hole of the square sleeve 73 is opened at its center.

[0077] The square column 64 is fitted inside the square sleeve 73 and passes through the square hole;

[0078] The side wall of the square sleeve 73 is provided with a bolt connection hole, and the locking bolt 74 is threadedly connected to the bolt connection hole, which can lock the square column 64.

[0079] In some further examples, at least one locking bolt 74 is installed on each of the two opposite sides of the square sleeve 73, so that the square sleeve 73 can be locked to the square post 64 from both sides.

[0080] In this embodiment, the base is used to improve the stability of the support mechanism, thereby indirectly improving the positional stability of the outer ring 30. The diameters of the upper cylinder 61 and the lower cylinder 63 are larger than the diameter of the supporting cylinder 50, thus providing a connecting circular surface with a larger cross-section than the supporting cylinder 50; the top ends of multiple short-range elastic elements 62 are respectively fixed to the bottom surface of the upper cylinder 61, and their bottom ends are respectively fixed to the top surface of the lower cylinder 63.

[0081] In a further example, multiple short-range elastic elements 62 are arranged in a circle, distributed around the perimeter and spaced equally in pairs. In another further example, multiple short-range elastic elements 62 are arranged in a circle, distributed around the perimeter and spaced equally in pairs, with another short-range elastic element 62 placed at the center of the circle. The center of the circle formed by the multiple short-range elastic elements 62 coincides with the axis of the upper cylinder 61. In the scheme where the short-range elastic element 62 is placed at the center of the circle, the central short-range elastic element 62 is located at the center of the circle and coincides with the axis of the upper cylinder 61.

[0082] The multiple short-range elastic elements 62 provided in this application are arranged in a circle, which makes the force distribution of the upper cylinder 61 and the lower cylinder 63 more uniform. On the other hand, because the length of the elastic elements is short, the elastic deformation is also smaller.

[0083] Furthermore, the length of the short-range elastic element 62 is 3-6 cm.

[0084] In some preferred embodiments, the short-range elastic element 62 is a short spring;

[0085] Multiple short springs have equal length, equal pitch, and equal outer diameter.

[0086] This application provides a recycling material conveying system, including a feeding mechanism 10 and a support and stabilizing device as described in any of the above embodiments;

[0087] The conveying steel pipe 11 of the feeding mechanism 10 is arranged obliquely, and the fastening bottom ring 20 is fastened and sleeved on the conveying steel pipe 11.

[0088] The support mechanism is placed vertically and is inclined relative to the end face of the fastening bottom ring 20.

[0089] In some preferred embodiments, the bottom surface of the feeding mechanism 10 is flush with the bottom surface of the support mechanism.

[0090] Furthermore, the bottom surface of the support column of the feeding mechanism 10 is flush with the bottom surface of the support leg 71 of the base. No rollers or pulleys are provided at the bottom of the base to ensure its stability when placed.

[0091] The anti-vibration working principle of the recycling material conveying system in this application is as follows:

[0092] The feeding mechanism 10 operates normally and feeds materials. The materials are transported obliquely upward from the conveying steel pipe 11 of the feeding mechanism 10 to increase the conveying capacity and increase the speed of the screw. The position with the largest shaking deviation of the conveying steel pipe 11 is detected and set as the point of maximum deviation, and then the machine is stopped.

[0093] At the point of maximum offset of the conveying steel pipe 11, first install the fastening bottom ring 20, and then tighten the fastening bottom ring 20 onto the conveying steel pipe 11. In order to ensure the tightness of the fit between the fastening bottom ring 20 and the outer wall of the conveying steel pipe 11, the outer diameter of the conveying steel pipe 11 needs to be measured when manufacturing the fastening bottom ring 20.

[0094] Then, the outer ring 30 is attached to the inner ring of the fastening bottom ring 20, and the support mechanism is then connected and fastened to the outer ring 30.

[0095] When installing the support mechanism, first connect and tighten the connecting sleeve 40 and the outer ring 30 with bolts, and then weld the support column 50 to the connecting sleeve 40 on site to ensure that the support column 50 is placed vertically.

[0096] When installing the base, first loosen the locking bolt 74 so that the square column 64 can move relative to the square sleeve 73; place the support leg 71 of the base stably on a flat ground, and then tighten the locking bolt 74 to lock the square column 64 and the square sleeve 73.

[0097] Before locking the square post 64, ensure that the short-range elastic element 62 is in a normal state, neither stretched nor compressed, and that the outer sleeve 30 is securely connected to the bottom fastening ring 20.

[0098] With this, the installation and fixation of the support and stabilization device of this application are completed, and the recycling material conveying system can be started and put into operation.

[0099] In operation, the wedge 23 is located in the downward direction of the entire fastening bottom ring 20, and at this time the first bottom half ring 21 is located diagonally above the second bottom half ring 22.

[0100] At this point, the conveying steel pipe 11 will not shake or vibrate, and its operation will be stable and without deviation. However, when the conveying steel pipe 11 deviates or vibrates, the connection between the fastening bottom ring 20 and the sleeve outer ring 30 becomes loose. Under the action of the short-range elastic element 62, the fastening bottom ring 20 and the sleeve outer ring 30 return to their original positions, thereby ensuring the stability of the connection between the two and stabilizing the position of the conveying steel pipe 11, thus reducing or even eliminating the vibration of the conveying steel pipe 11.

[0101] Specifically, when the upward vibration offset of the conveying steel pipe 11 is large, the short-range elastic element 62 is in a stretched state. Under its tension, the downward force on the outer sleeve 30 is increased, promoting the outer sleeve 30 to move closer to the stepped surface of the fastening bottom ring 20. When the downward vibration offset of the conveying steel pipe 11 is large, the short-range elastic element 62 is in a compressed state. Under its elastic force, the conveying steel pipe 11 is pushed upward back to its original position. Ultimately, regardless of the vibration state, anti-shaking and anti-vibration measures can be guaranteed, ensuring the stable operation of the conveying steel pipe 11.

[0102] Since the vibration offset of the conveying steel pipe 11 in the left and right directions is small, it can be ignored.

[0103] The recycling material conveying system of this application can ensure the smooth operation of the entire system during the conveying and feeding process, thereby ensuring the high efficiency of the entire system.

[0104] The embodiments described above are merely examples of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
