Therefore, the first feeding roller 11 and the second feeding roller 12 are easy to bend downwards under the action of their own gravity, and the linearity is poor and the deflection is large, which affects the working efficiency and the service life of the feeding mechanism 1200.

In this embodiment, the first feeding roller 11 and the second feeding roller 12 are made of high-strength alloy tubes by encapsulation, wherein the encapsulation has certain elasticity, which is helpful for increasing friction force and clamping glass waste; the high-strength alloy pipe can obviously improve the rigidity and the strength of the first feeding roller 11 and the second feeding roller 12, so that the straightness is good.

Referring to fig. 8 to 10, in the actual production process, since the radius R of the conveying wheel 2001 is large, a certain gap is inevitably formed between the conveying belt 2000 and the feeding mechanism 1200, so that narrow glass waste is easily dropped into the gap and cannot enter the casing 1100, which results in low working efficiency of the glass mincing device 1000. In order to solve the above technical problem, the glass mincing device 1000 of this embodiment further has set up the auxiliary feeding mechanism 1300 in the outside of the feeding mechanism 1200, and the auxiliary feeding mechanism 1300 and the feeding mechanism 1200 are mutually matched, can effectively reduce the quantity of the glass waste falling into the gap.

Referring to fig. 11-14, the glass waste can be ground in the grinding zone after entering the enclosure 1100. The mincing region in this embodiment mainly plays a role of primary mincing, which is to pulverize the large-sized glass waste into small pieces, and a deep mincing mechanism (not shown in the figure) may be further provided in the subsequent stage, and the specific structure of the deep mincing mechanism may adopt the prior art, and the present invention is not limited thereto.

The mincing mechanism 1400 includes a mincing shaft 4, in this embodiment, the mincing shaft 4 specifically includes a first mincing shaft 41 and a second mincing shaft 42, the first mincing shaft 41 is rotatably disposed on the casing 1100 around a fourth rotation center line p, the second mincing shaft 42 is rotatably disposed on the casing 1100 around a fifth rotation center line q, the fourth rotation center line p and the fifth rotation center line q are parallel to each other and both extend along the X direction, the fourth rotation center line p is located above the fifth rotation center line q, the rotation directions of the first mincing shaft and the second mincing shaft are opposite, the first mincing shaft and the second mincing shaft hit the glass waste at the same time, the glass waste is ground, and the ground glass waste can be continuously transmitted along the Y direction for subsequent treatment.

In this embodiment, the first mincing shaft 41 and the second mincing shaft 42 have the same structure, and the first mincing shaft 41 is taken as an example for specific explanation. The first mincing rotating shaft 41 is fixedly provided with a plurality of blades 51, each blade 51 extends along the X direction, and each blade 51 protrudes and extends along the radial direction of the first mincing rotating shaft 41. For the convenience of assembly, the blades 51 are made in the form of blade sets 50, each blade set 50 is actually a metal plate extending along the X direction, the middle part of the blade set 50 is concave to form a connecting part 52 extending along the X direction, two sides of the blade set 50 are convex to form two blades 51 arranged at intervals, and the connecting part 52 is fixedly arranged on the first mincing rotating shaft 41 and is connected with the first mincing rotating shaft by bolts. In this way, each vane assembly 50 can be made independently and then assembled to the first mincing shaft 41, reducing the difficulty of production and installation. In this embodiment, in order to facilitate the manufacturing and ensure the strength of each blade 51, the length of each blade group 50 is short, therefore, along the X direction, the first mincing rotating shaft 41 is sequentially provided with the plurality of blade groups 50, and the two adjacent blade groups 50 are attached to each other or have a small gap therebetween, so as to prevent the unabraded glass waste from directly passing through between the two blade groups 50, and the blade groups 50 are disposed on the portions of the first mincing rotating shaft 41 located in the mincing region, so as to ensure that the glass waste entering the mincing region can contact with the blades 51 and be minced. On the other hand, a plurality of blade groups 50 are provided at intervals in the circumferential direction of the first mincing rotating shaft 41 so as to continuously hit the glass waste material during the rotation of the first mincing rotating shaft 41. In the present embodiment, three sets of blades 50, that is, six blades 51, are provided along the circumferential direction of the first mincing shaft 41.

Further, each of the vanes 51 is fixedly provided with a plurality of rubbing convex portions 6, and each rubbing convex portion 6 is in a cylindrical shape extending along the radial direction of the first rubbing rotary shaft 41. In the same vane 51, a plurality of rubbing convex portions 6 are provided at intervals in the X direction, and the rubbing convex portions 6 are located on the front side of the vane 51 in the rotation direction of each vane 51. The outer end of the mincing projection 6 is flush with the outer end of the blade 51 in the radial direction of the first mincing shaft 41. Therefore, in the rotating process of the first mincing rotating shaft 41, the mincing convex part 6 can contact the glass waste before the blades 51, and the contact between the mincing convex part 6 and the glass waste is 'point' contact, so that the acting pressure is high, and the glass waste is easier to be crushed into smaller fragments. Referring to fig. 14, since the rotation directions of the first mincing rotating shaft 41 and the second mincing rotating shaft 42 are opposite, the relative positions of the mincing convex part 6 and the blade 51 on the two mincing rotating shafts are also opposite. In addition, the shortest distance between the outer surface of the first mincing rotating shaft 41 and the outer surface of the second mincing rotating shaft 42 is less than twice the height of the single blade 51, so that the blades 51 on the first mincing rotating shaft 41 and the blades 51 on the second mincing rotating shaft 42 can be staggered in the vertical direction, and the crushing effect on the glass waste is enhanced. In this embodiment, the vanes 51 and the mincing convex portions 6 are made of hard metal materials to ensure effective fragmentation of the glass waste.

In addition, in this embodiment, the first mincing shaft 41 is a driving mincing shaft, the second mincing shaft 42 is a driven mincing shaft, the mincing mechanism 1400 further includes a transmission component for driving the second mincing shaft 42 to rotate reversely when the first mincing shaft 41 rotates, and a driving mechanism for driving the first mincing shaft 41 to rotate, and the driving mechanism is specifically the second motor 82 disposed at one end of the first mincing shaft 41. The transmission assembly comprises a first mincing gear 71 fixedly arranged at one end of the first mincing rotating shaft 41 and a second mincing gear 72 fixedly arranged at one end of the second mincing rotating shaft 42, and the first mincing gear 71 and the second mincing gear 72 are meshed with each other. In this way, when the second motor 82 drives the first mincing rotating shaft 41 to rotate counterclockwise, the first mincing rotating shaft 41 can rotate clockwise in conjunction with the second mincing rotating shaft 42 through the transmission assembly.

The working principle of the glass mincing system and the glass mincing device 1000 in the embodiment is specifically described as follows:

referring to fig. 1 and 2, the conveyor belt 2000 transports the glass waste along the Y direction at a linear velocity v, the glass waste may be transported in any direction, the transmission roller 13 receives the glass waste at the same linear velocity v and transmits the glass waste to the space between the first feeding roller 11 and the second feeding roller 12, and the first feeding roller 11 and the second feeding roller 12 continue to transport the glass waste to the mincing region at the linear velocity v.

The blades 51 on the first mincing rotating shaft 41 and the second mincing rotating shaft 42 also reversely rotate at the linear velocity v, so that the glass waste can firstly contact and collide with the mincing convex parts 6 after entering the mincing region, and the mincing convex parts 6 are cylindrical and generate point-to-surface contact with the glass waste, so that the pressure is high, and the glass waste can be firstly broken into small sizes. As the first mincing shaft 41 and the second mincing shaft 42 continue to rotate, the smaller-sized glass fragments continue to collide with the blades 51, generating a "line-to-plane" contact, and are minced into smaller fragments. The glass fragments primarily ground by the grinding mechanism 1400 continue to advance by the rotation of the vanes 51, and can be transmitted to a subsequent processing mechanism.

The above steps are continuously performed, and the conveyor belt 2000 continuously transmits the glass waste to the glass mincing device 1000, so as to realize the continuous operation of the glass mincing system. And the glass waste entering the mincing region at any angle can be effectively crushed, and the phenomenon of 'blocking' can not occur.

In summary, in the glass mincing system and the glass mincing device 1000 with the feeding auxiliary mechanism 1300 of the embodiment, the straightness of the first feeding roller 11 and the second feeding roller 12 is good, the service life is long, the installation is convenient, the glass waste can be stably conveyed, the glass waste falling into the gap between the conveyor belt 2000 and the glass mincing device 1000 is greatly reduced, and the mincing efficiency is improved; the load of the second motor 82 can be reduced, the clamping is prevented, the abrasion of the blades 51 is reduced, the service life of the blades 51 is prolonged, the glass can be ground more completely, and the subsequent crushing load is reduced.
