[0037] Specifically, the lifting belt 2 is provided with two gaps, and the lifting belt 2 can be driven to rotate, a plurality of installation rods 5 are installed between the two lifting belts 2, and the installation rods 5 can be driven to move along with the lifting belt 2 when the lifting belt 2 is driven to rotate, so as to lift the installation rods 5, and a movable sleeve 52 is rotatably sleeved outside the installation rod 5, the movable sleeve 52 can only rotate outside the installation rod 5 but cannot be positionally deviated along the length direction of the installation rod 5, and a magnet piece 53 is embedded on both sides of the surface of the movable sleeve 52, and the magnetic poles of the two magnet pieces 53 are consistent, so that the magnetic poles of the two sides of the movable sleeve 52 are N and S poles respectively;

[0038] Secondly, the lifting frame 4 is installed on one side of the installation rod 5, and the lifting frame 4 can be driven to move along with the installation rod 5 when the installation rod 5 is lifted and moved, the lifting frame 4 comprises a connecting seat 41, the connecting seat 41 is fixedly connected with the installation rod 5 through bolts, the lifting frame 4 is detachable with the installation rod 5, so as to facilitate replacement of the lifting frame 4 when the lifting frame 4 is damaged, two parallel lifting rods 42 are fixed on the surface of the connecting seat 41, and the lifting rods 42 are in the shape of “|”, as shown in the figure, when the lifting frame 4 is rotated to a horizontal position or an upwardly inclined position, the rubber ring material can be sleeved and hung outside the lifting frame 4, so as to facilitate lifting and transferring of the rubber ring material by the lifting frame 4, and even if the machine vibrates during work, the rubber ring material can be relatively stably hung on the lifting frame 4, so as to avoid scattering of the material, and a fixing rod 43 is fixed between the two lifting rods 42, which can be used to keep the fixing connection between the two lifting rods 42; Figure 5

[0039] Further, the blocking plate 6 is arranged on one side of the installation rod 5, the blocking plate 6 is slidably sleeved outside the lifting frame 4, the blocking plate 6 can only slide a certain distance along the length direction of the lifting frame 4, a magnet block 63 corresponding to the movable sleeve 52 is fixedly embedded on the surface of the blocking plate 6, when the magnet pieces 53 on the movable sleeve 52 and the magnet block 63 on the blocking plate 6 attract each other, the blocking plate 6 slides close to the installation rod 5, at this time, the front end of the lifting frame 4 is exposed, and the rubber ring material can be hung on the front end of the lifting frame 4, on the contrary, when the magnet pieces 53 on the movable sleeve 52 and the magnet block 63 on the blocking plate 6 repel each other, the blocking plate 6 slides away from the installation rod 5, at this time, the blocking plate 6 can push the rubber ring material hung on the lifting frame 4, so as to separate the material from the lifting frame 4 and realize automatic unloading;

[0040] In addition, arc-shaped plates 31 are arranged at the upper and lower ends between the two lifting belts 2, when the installation rod 5 approaches the arc-shaped plate 31, the movable sleeve 52 is extruded and rotated by one hundred and eighty degrees on the surface of the arc-shaped plate 31, in combination with Figure 3 and Figure 10 ​As shown, when the lifting frame 4 moves to the upper end position of the lifting belt 2, the movement track of the lifting frame 4 is a semicircular arc, at this time, the movable sleeve 52 is in contact with the arc-shaped plate 31, the movable sleeve 52 will rotate on the outside of the mounting rod 5, thereby changing the magnetic pole orientation on both sides of the movable sleeve 52, so that the material blocking plate 6 changes from the state of being close to the mounting rod 5 to the state of being away from the mounting rod 5, and the material blocking plate 6 slides away from the mounting rod 5, so that the rubber ring material hung on the lifting frame 4 can be pushed off the lifting frame 4, and similarly, when the lifting frame 4 moves to the lower end position of the lifting belt 2, the movable sleeve 52 rotates by 180 degrees again, and the material blocking plate 6 slides close to the mounting rod 5 again, so that the front end of the lifting frame 4 is exposed, thereby facilitating the hanging of the rubber ring material.

[0041] In order to avoid the phenomenon of slipping between the movable sleeve 52 and the arc-shaped plate 31, the application also has a tooth groove arranged on the surface of the movable sleeve 52, and the arc-shaped teeth 32 corresponding to the movable sleeve 52 are arranged on the surface of the arc-shaped plate 31, so that when the movable sleeve 52 and the arc-shaped plate 31 approach and contact each other, the tooth groove on the surface of the movable sleeve 52 and the arc-shaped teeth 32 mesh with each other, thereby avoiding the phenomenon of slipping between the movable sleeve 52 and the arc-shaped plate 31, and in addition, the width dimension of the arc-shaped plate 31 is half of the circumference dimension of the movable sleeve 52, so that during the process of the movable sleeve 52 passing through the arc-shaped plate 31, the movable sleeve 52 can only rotate by 180 degrees, and the rubber layer for increasing friction is arranged between the movable sleeve 52 and the mounting rod 5, so that when the movable sleeve 52 is separated from the arc-shaped plate 31, the movable sleeve 52 will not easily rotate to affect the magnetic pole orientation on both sides thereof.

[0042] In order to install and connect the material blocking plate 6 with the lifting frame 4, the material blocking plate 6 of the application comprises splice plate one 61 and splice plate two 62, and the two are spliced and fixed by bolts, as shown in Figure 6 As shown, the material blocking plate 6 itself is a detachable splicing structure, which can be conveniently installed and detached with the lifting frame 4, and the through hole 64 is arranged on the surface of the material blocking plate 6, the through hole 64 is arranged in two groups and corresponds to the two lifting rods 42 on the lifting frame 4 respectively, the through hole 64 cooperates with the lifting rod 42 to ensure that the material blocking plate 6 can only slide along the length direction of the lifting frame 4, and the fixing rod 43 can limit the sliding of the material blocking plate 6, in addition, the lifting frame 4 and the movable sleeve 52 are arranged in multiple and are sequentially and spacedly distributed along the length direction of the mounting rod 5, the through hole 64 is arranged in multiple groups and corresponds to the multiple lifting frames 4 respectively, as shown in Figure 4 and Figure 5 As shown, the multiple lifting frames 4 on one mounting rod 5 can simultaneously hang multiple rubber ring materials, and the multiple rubber ring materials can be simultaneously pushed by one material blocking plate 6, that is, the material blocking plate 6 can simultaneously unload the rubber ring materials on the multiple lifting frames 4 when sliding.

[0043] In order to limit the sliding stroke of the material blocking plate 6, the fixed rod 43 on the lifting frame 4 of the present application is provided with two groups, and is located at both ends of the lifting rod 42. The material blocking plate 6 is located between the two fixed rods 43 and slides. The two fixed rods 43 can be used to limit the sliding stroke of the material blocking plate 6, so as to avoid the material blocking plate 6 being stuck due to sliding to the front end bending part of the lifting frame 4. In addition, the lifting belt 2 is inclined as a whole, and the lifting frame 4 is perpendicular to the surface of the lifting belt 2. As shown in Figure 1 and Figure 2 It can be seen that when the lifting frame 4 of the device lifts the rubber ring material, the lifting frame 4 is in an inclined upward state, which can effectively prevent the rubber ring material from falling off the lifting frame 4. When the lifting frame 4 is lowered, the lifting frame 4 is in an inclined downward state, which can more easily and conveniently unload the rubber ring material.

[0044] In order to install the mounting rod 5 outside the lifting belt 2, the present application also has a plurality of connecting sleeves 22 fixedly arranged on the surface of the lifting belt 2 at equal intervals. The two ends of the mounting rod 5 are fixedly connected with the connecting frame 51. The connecting frame 51 is arranged in the shape of a "Fang" character, and the two ends of the connecting frame 51 are respectively inserted into the inner cavities of the adjacent two connecting sleeves 22. As shown in Figure 4 and Figure 5 It can be seen that the arrangement of the connecting frame 51 can install the mounting rod 5 between the two lifting belts 2, and the mounting rod 5 itself will not rotate, thereby ensuring the stability of the lifting frame 4 during movement.

[0045] In order to avoid the local area of the lifting belt 2 from being bent and deformed, the present application also has a rack 1 arranged outside the lifting belt 2. The rack 1 includes a protective cover 11 and a guide frame 12, and the two are fixedly connected. The guide frame 12 is located on one side of the lifting belt 2. The guide frame 12 is internally provided with a groove. The side surface of the lifting belt 2 is fixedly connected with a plurality of guide pins 21 arranged at equal intervals. The guide pins 21 are located in the groove in the guide frame 12 and are in sliding connection with the groove. As shown in Figure 2 and Figure 7 It can be seen that the guide pins 21 and the groove in the guide frame 12 limit each other, which can avoid the local bending and deformation of the lifting belt 2.

[0046] In order to drive the transmission rotation of the lifting belt 2, the application also has a driving motor 111 fixed on the surface of the protective cover 11, and the driving motor 111 drives the rotation of the pulley 231 through the transmission belt, and the driving motor 111 drives the rotation of the pulley 231 and the transmission wheel 23 through the belt when the driving motor 111 works, so as to drive the transmission rotation of the lifting belt 2. The lifting belt 2 is provided with a fixed shaft 24 at the upper and lower ends, the fixed shaft 24 is fixedly connected with the protective cover 11, the transmission wheel 23 is rotatably arranged outside the protective cover 11, and the fixed shaft 24 remains fixed in position. The transmission wheel 23 can only rotate outside the fixed shaft 24.

[0047] In order to install and fix the arc-shaped plate 31, a plurality of annularly arranged notch grooves 232 are formed in one side edge of the transmission wheel 23, the guide pin 21 moves with the transmission of the lifting belt 2 and is clamped into the inner cavity of the notch groove 232, and the notch groove 232 is mainly used for cooperation with the guide pin 21, so as to avoid the slipping phenomenon between the lifting belt 2 and the transmission wheel 23. The shaft sleeve 3 is arranged outside the middle part of the fixed shaft 24, and the arc-shaped plate 31 is fixedly installed outside the shaft sleeve 3. Since the fixed shaft 24 remains fixed in position and cannot rotate, the arc-shaped plate 31 and the shaft sleeve 3 can remain fixed in position, so as to avoid the position deviation of the arc-shaped plate 31 in the process of passing through the movable sleeve 52.

[0048] In order to adjust the installation position of the arc-shaped plate 31, a slot is formed on the surface of the shaft sleeve 3 to form a "C" shaped structure, two strip-shaped plates are fixed on the both sides of the slot of the shaft sleeve 3, and the two strip-shaped plates are fixedly connected by bolts. The shaft sleeve 3 is made of a hard material capable of elastic deformation, and a rubber pad for increasing friction is arranged between the inner wall of the shaft sleeve 3 and the surface of the fixed shaft 24. Figure 8 and Figure 9 As shown in the figure, the shaft sleeve 3 can be elastically deformed to a certain extent, and the shaft sleeve 3 can be fixedly arranged outside the fixed shaft 24 by tightening the bolts at the slot position. In addition, the installation position of the arc-shaped plate 31 can be adjusted by loosening the bolts.

[0049] In order to facilitate the automatic suspension of the rubber ring material by the lifting frame 4, the upper and lower ends of the rack 1 are respectively provided with an upper conveying frame 7 and a lower conveying frame 8, a distribution plate 81 is formed at the edge of the surface of the lower conveying frame 8, and the distribution plate 81 corresponds to the lifting frame 4. A silica gel layer is fixedly bonded to the inner wall of the inner cavity of the distribution plate 81, and a notch groove is formed in the middle of the silica gel layer. An opening groove 82 is fixed on the surface of the lower conveying frame 8, and the opening groove 82 is spaced apart from the distribution plate 81. Figure 11As shown, the rubber ring material conveyed on the lower conveying frame 8 can be separated into multiple groups by the open groove 82, and then combined Figure 2 and Figure 4 As shown, the lifting frame 4 can pass through the material distribution plate 81 when moving, and the front end of the lifting frame 4 can pass through the rubber ring material from bottom to top to achieve suspension of the rubber ring material. The silica gel layer provided in the inner cavity of the material distribution plate 81 has elastic deformation capability, which is to avoid the rubber ring material from falling off from the material distribution plate 81.
