[0033] In combination Figure 1 , Figure 2 And Figure 3As shown, the automatic discharging round bar polishing machine provided by the embodiment comprises a rack 1 and a tooth type pushing assembly arranged on the rack 1. The tooth type pushing assembly performs linear reciprocating motion on the rack 1. The rack 1 and the tooth type pushing assembly are sequentially connected in communication in the direction of a polishing path, and form an inlet inclined bin 2, a polishing inclined space 3 and a discharging inclined bin 4. A lifting type elastic material pressing assembly is arranged in the polishing inclined space 3 and is spaced apart from the tooth type pushing assembly. An inclined material pushing mechanism is arranged at the connection between the inlet inclined bin 2 and the polishing inclined space 3. A discharging control mechanism is arranged at the connection between the polishing inclined space 3 and the discharging inclined bin 4.

[0034] It can be understood that, in the embodiment, the rack 1 provides stable structural support. The tooth type pushing assembly performs linear reciprocating motion on the rack 1, and is used for pushing the round bar to move along the polishing path. The round bar enters from the inlet inclined bin 2, is polished in the polishing inclined space 3, and is finally discharged through the discharging inclined bin 4. The lifting type elastic material pressing assembly applies appropriate pressure to the round bar during polishing, so as to ensure the polishing effect. The inclined material pushing mechanism and the discharging control mechanism are respectively responsible for the orderly feeding and discharging of the round bar, and ensure the continuity of the entire polishing process.

[0035] In a specific embodiment of the present application, as shown in Figure 1 and Figure 4 , the inclined material pushing mechanism comprises an inclined material pushing gear 21, and the tooth groove of the inclined material pushing gear 21 is used for accommodating the material to be polished. A material pushing driving assembly is arranged for driving the inclined material pushing gear 21 to rotate.

[0036] Specifically, the material pushing driving assembly comprises a material pushing driver 22 arranged on the rack 1 and a chain transmission structure 23. The chain transmission structure 23 is respectively connected with the power end of the material pushing driver 22 and the inclined material pushing gear 21. The material pushing driver 22 drives the inclined material pushing gear 21 to rotate through the chain transmission structure 23, so as to drive the material to be polished in the tooth groove of the inclined material pushing gear 21 to enter the polishing inclined space 3.

[0037] Specifically, the chain transmission structure 23 in the embodiment can be a roller chain or a toothed chain. The material pushing driver 22 can be an electric motor or a hydraulic motor. For example, the electric motor transmits power to the roller chain through a speed reducer, and the roller chain transmits power to the inclined material pushing gear 21, so as to realize efficient and stable material conveying and polishing process.

[0038] It can be understood that the inclined type of the material stirring mechanism in the embodiment is mainly used to move the material to be polished from the material inlet inclined bin 2 to the polishing inclined space 3, so as to perform the polishing operation; the material to be polished in the gear groove is transferred to the polishing inclined space 3 by driving the rotating inclined material stirring gear 21 by the material stirring driving assembly, and the uniform distribution of the material to be polished in the polishing process is ensured, the efficient and stable material conveying and polishing process is realized, the production efficiency is improved, and the consistency and reliability of the polishing quality are ensured.

[0039] In a specific embodiment of the present application, as shown in Figure 7 The tooth type pushing assembly is provided with a containing groove / hole 52 for containing the inclined material stirring gear 21, and at least part of the inclined material stirring gear 21 protrudes from the upper end of the containing groove / hole 52. That is, at least part of the inclined material stirring gear 21 is exposed at the communication between the material inlet inclined bin 2 and the polishing inclined space 3. The containing groove / hole 52 is, for example, a containing groove or a containing hole.

[0040] Specifically, the material to be polished contained in the gear groove of at least part of the inclined material stirring gear 21 exposed to the material inlet inclined bin 2 is moved to the polishing inclined space 3 in the rotating process of the inclined material stirring gear 21, and the material to be polished contained in the gear groove of the inclined material stirring gear 21 follows the rotation and falls into the polishing inclined space 3, thereby realizing the transfer of the material to be polished and facilitating the polishing.

[0041] As another solution, the inclined type of the material stirring mechanism in the embodiment includes a conveying belt group at least partially exposed to the containing groove / hole 52 and a driver one driving the rotation of the conveying belt group, and a plurality of placing grooves containing the material to be polished are arranged on the surface of the conveying belt group. One end of the conveying belt group is located in the material inlet inclined bin 2, and the other end is located in the polishing inclined space 3. The material to be polished in the placing groove is moved from the material inlet inclined bin 2 to the polishing inclined space 3 by rotating the conveying belt group, and falls onto the tooth type pushing assembly for polishing treatment.

[0042] It can be understood that the containing groove / hole 52 in the embodiment enables the inclined material stirring gear 21 to work at a specific position, and ensures that the material can be smoothly transferred from one processing stage to another processing stage, thereby realizing a continuous production process.

[0043] In a specific embodiment of the present application, as shown in Figure 2 and Figure 8 The lifting type of the elastic material pressing assembly includes a moving cross beam 61 and an elastic material pressing plate 62. The two ends of the elastic material pressing plate 62 are respectively connected to the moving cross beam 61, the moving cross beam 61 is connected with the lifting driving mechanism, and the moving cross beam 61 and the elastic material pressing plate 62 are distributed in an up-down manner.

[0044] Specifically, the lifting driving mechanism drives the moving crossbeam 61 and the elastic pressing plate 62 to move up and down. When polishing, the lifting driving mechanism drives the moving crossbeam 61 and the elastic pressing plate 62 to move down, so that the elastic pressing plate 62 contacts and exerts a certain pressure on the material to be polished. At this time, the tooth type pushing assembly moves linearly and reciprocally, and the polishing process of the material to be polished is realized through the cooperation of the tooth type pushing assembly and the elastic pressing plate 62.

[0045] It can be understood that, in the embodiment, the moving crossbeam 61 connects and supports the elastic pressing plate 62 and the lifting driving mechanism, and quickly responds to the action of the lifting driving mechanism to drive the moving crossbeam 61 and the elastic pressing plate 62 to move up and down. The tooth type pushing assembly moves linearly and reciprocally, and cooperates with the elastic pressing plate 62 to ensure the coordination of force and movement during polishing, thereby forming an efficient polishing system.

[0046] In one specific embodiment of the present application, as shown in Figure 8 A material level detection sensor 63 is arranged on the elastic pressing plate 62.

[0047] Specifically, the material level detection sensor 63 and the lifting driving mechanism in the embodiment are respectively in communication connection with the controller. When the material level detection sensor 63 detects the corresponding material level height of the polishing material in the polishing inclined space 3, the controller controls the lifting driving mechanism to drive the elastic pressing plate 62 to move up and down to a set height. The controller is, for example, a PLC sensor, and the material level detection sensor 63 is, for example, an ultrasonic sensor or a photoelectric sensor, which can monitor the height change of the polishing material in real time and respond quickly.

[0048] In one specific embodiment of the present application, as shown in Figure 1 and Figure 2 The lifting driving mechanism is a synchronous transmission type lifting driving mechanism, which includes two lifting drivers 641 fixed to the rack 1. One power end of one of the two lifting drivers 641 is connected to one end of the moving crossbeam 61, and the power end of the other lifting driver 641 is connected to the other end of the moving crossbeam 61. The two ends of the moving crossbeam 61 are respectively slidably connected to the rack 1 through guide pairs, and at least part of the two guide pairs are respectively connected to the synchronous transmission structure on the rack 1.

[0049] Specifically, the lifting driver 641 in the embodiment is, for example, a pneumatic cylinder, an oil cylinder or a linear motor.

[0050] Specifically, the lifting driving mechanism in the embodiment drives the movement cross beam 61 to move up and down by connecting the power end of the two lifting drivers 641 to one end of the movement cross beam 61 respectively. Meanwhile, the guide vice is arranged to connect the movement cross beam 61 and the rack 1 respectively, so as to accurately control the movement direction of the movement cross beam 61 and ensure that the lifting driving mechanism runs along the preset path during operation, thereby realizing the lifting movement of the elastic pressing plate 62 driven by the movement cross beam 61.

[0051] It can be understood that the lifting driving mechanism in the embodiment realizes the lifting movement of the movement cross beam 61 by the two lifting drivers 641, and the synchronous transmission structure ensures the coordinated work of the two lifting drivers 641, ensures the stability and consistency of the movement, and avoids mechanical failure or movement error caused by asynchronization. The guide vice is used to limit the movement direction of the movement cross beam 61, so that it moves along the predetermined path. Through the sliding connection, the guide vice ensures the vertical movement of the movement cross beam 61 and prevents lateral deviation, thereby improving the accuracy and reliability of the polishing machine.

[0052] In one specific embodiment of the present application, as shown in Figure 9 the synchronous transmission structure includes two groups of transmission chain / belt groups 644 rotatably connected to the rack 1, and one transmission chain / belt group 644 is fixedly connected to at least part of one guide vice. Among them, the transmission chain / belt group 644 is, for example, a transmission chain group or a transmission belt group.

[0053] Specifically, when the transmission chain / belt group 644 in the embodiment is selected as a transmission belt, the transmission belt is a synchronous belt, and the synchronous belt is wound around two synchronous pulleys. The guide vice includes a guide shaft 642 and a guide sleeve 643, and the guide sleeve 643 is connected to the transmission chain / belt group.

[0054] It can be understood that the synchronous transmission structure in the embodiment is composed of two groups of transmission chain / belt groups 644 rotatably connected to the rack 1, and at least part of the chain links / belts of one transmission chain / belt group 644 is connected to the guide sleeve 643 of one guide vice. When the guide sleeve 643 follows the lifting movement of the movement cross beam 61, it drives the transmission chain / belt group 644 to rotate. Further, by combining the transmission chain / belt group 644 with the guide vice, the movement of the guide sleeve 643 drives the rotation of the transmission chain / belt group, realizes the consistency of the two transmission chain / belt groups 644, and also enhances the stability and reliability of the whole.

[0055] In one specific embodiment of the present application, as shown in Figure 5 and Figure 6 the discharge control mechanism is an inclined discharge mechanism, which includes a discharge gate 41 hinged to the rack 1 and a gate driver 42 driving the discharge gate 41 to rotate around the hinge point.

[0056] Specifically, the gate drive 42 in the embodiment is, for example, a cylinder, an oil cylinder or a linear motor.

[0057] Specifically, the power end of the gate drive 42 in the embodiment can be connected to the other end of the hinged connection between the discharge gate 41 and the rack 1, and the lying or inclined state of the discharge gate 41 can be driven by the extension or retraction movement of the power end of the gate drive 42.

[0058] Specifically, the inclined discharge mechanism in the embodiment can further include two rotating plates 43 connected by a rotating shaft at one end, and the other end of one rotating plate 43 is rotatably connected to the other end of the hinged connection between the discharge gate 41 and the rack 1, and the remaining rotating plate 43 is rotatably connected to the rack 1. Meanwhile, the power end of the gate drive 42 is connected to the rotating shaft of the two rotating plates 43. When the power end of the gate drive 42 is extended, the two rotating plates 43 are in a straight line, and at this time the discharge gate 41 is pushed open by the rotating plate 43 to an inclined state; when the power end of the gate drive 42 is retracted, the smallest angle is formed between the two rotating plates 43, and at this time the discharge gate 41 is pulled back to a lying state.

[0059] It can be understood that in the embodiment, when different materials to be polished are replaced, the discharge gate 41 can be completely in a lying state, so that the material in the polishing space can be emptied to the maximum extent, so as to reduce the amount of manual material that has not been emptied, thereby improving the efficiency of replacing the material and shortening the downtime. When the gate is in an inclined state, the communication between the polishing inclined space 3 and the discharge inclined bin 4 is closed to facilitate polishing.

[0060] As another solution, the discharge control mechanism of the embodiment includes a lifting gate connected to a lifting drive, which is a cylinder, an oil cylinder or a linear motor.

An eccentric drive device 55 is provided on the rack 1 and is hingedly connected with the reciprocating moving plate 51.

[0062] It can be understood that the reciprocating plate 51 moves back and forth in the rack 1, and the upper surface of the reciprocating plate 51 is provided with a plurality of convex teeth 53, so that the reciprocating plate 51 can effectively contact the material to be polished in the polishing inclined space 3 during movement, and increase the friction. The hinged frame 54 is fixed to the rack 1 by hinging the reciprocating plate 51, allowing the reciprocating plate 51 to freely swing within a certain angle range, thereby realizing flexible movement. The eccentric drive device 55 uses the principle of eccentric wheel to generate reciprocating motion, and through the rotation of the eccentric wheel, the reciprocating plate 51 can be driven to move periodically up and down or left and right, thereby realizing the linear reciprocating motion of the reciprocating plate 51 on the rack 1.

[0063] In a specific embodiment of the present application, two cantilever frames 11 are arranged on the rack 1 and located above the tooth type pushing assembly, and the two cantilever frames 11 are respectively in sliding connection with the lifting type elastic material pressing assembly. One side of one of the cantilever frames 11, the inclined slope 12 of the rack 1 and the tooth type pushing assembly form the material inlet inclined bin 2, one side of the other cantilever frame 11, the inclined plate 13 on the rack 1 and the tooth type pushing assembly form the material outlet inclined bin 4, and the opposite sides of the two cantilever frames 11 and the tooth type pushing assembly form the polishing inclined space 3.

[0064] Specifically, the two cantilever frames 11 in the embodiment are respectively in sliding connection with the guide pair of the lifting type elastic material pressing assembly, providing support for the lifting type elastic material pressing assembly.
