[0024] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following embodiments are used to illustrate the technical solution of the present invention, but are not intended to limit the scope of protection of the present invention.

[0025] Example:

[0026] As attached Figures 1 to 6 As shown:

[0027] The utility model provides a dual-track synchronous unloading mechanism for automatic grinding equipment, which includes a movable table 10 and a base 11. A gap is provided between the movable table 10 and the base 11. The user can push the movable table 10 for adjustment. A vibration plate 12 is provided on the top of the movable table 10. After the springs are disassembled and ground by an external device, the springs are queued from the external device and enter the vibration plate 12. Two sets of spring outlets 13 are provided in the vibration plate 12. The vibration plate 12 can transport the internal springs to the spring outlets 13 through its own vibration, and the user can control the discharge speed of the vibration plate 12 through the vibration feeding controller 35. The degree of control is performed, and a queuing double track 14 is provided at one end of the two groups of spring outlets 13. The queuing double track 14 can convey the springs coming out of the spring outlet 13, and the queuing double track 14 has two tracks, which can convey two groups of springs at the same time. A discharging mechanism 15 is provided at one end of the queuing double track 14. The queuing double track 14 can convey the two groups of springs to the discharging mechanism 15. Two groups of discharging ports 16 are provided at the bottom of the discharging mechanism 15. The discharging mechanism 15 can convey the two groups of springs to the discharging port 16. There are also two groups of discharging ports 16, which can convey the two groups of springs at the same time. The bottom of the two groups of discharging ports 16 The same feeding assembly is provided, and the two groups of springs enter the feeding assembly from the discharge port 16. The feeding assembly can feed the two groups of springs into the feeding tray slot 271 of the uniformly rotating feeding tray 27. A positioning assembly is provided at the bottom of the feeding assembly. The positioning assembly can position the feeding assembly to prevent the feeding assembly from being offset or shifted during the feeding process, resulting in poor feeding accuracy. The uniformly rotating feeding tray 27 rotates at a uniform speed. When the traditional unloading mechanism feeds the springs, the feeding time will be affected by various factors, resulting in different feeding times. The feeding time is difficult to match the turntable speed, and the springs will often not be fed into the feeding tray slot 271. Inside, through the setting of the positioning component, the feeding accuracy of the mechanism is effectively improved. A uniformly rotating material tray 27 is provided at the bottom of the positioning component, and multiple groups of material tray slots 271 are opened on the top of the uniformly rotating material tray 27. These material tray slots 271 are used to accommodate springs, and the springs will be fed into the positioning slots 272 of the uniformly rotating material tray 27 by the feeding mechanism. A material tray main shaft 30 is passed through the top of the uniformly rotating material tray 27. When the material tray main shaft 30 rotates at a uniform speed, it will drive the uniformly rotating material tray 27 to rotate at a uniform speed at the same time. A fixed bracket 24 is provided on the material tray main shaft 30, and the fixed bracket 24 does not rotate synchronously with the material tray main shaft 30.

[0028] After the ground spring enters the vibration disk 12, the spring is transported from the spring outlet 13 to the queuing double track 14 through the vibration disk 12. The spring enters the discharging mechanism 15 via the queuing double track 14. The discharging mechanism 15 transports the spring from the discharge port 16 to the feeding port 23. The feeding assembly feeds the spring from the feeding port 23 to the feeding tray slot 271 at the top of the uniformly rotating feeding tray 27, completing a single feeding operation.

[0029] Among them, see Figure 1、 Figure 2 and Figure 6 As shown, the feeding assembly includes a first cylinder 20, which is arranged on the top of the fixed bracket 24. The user can install the connecting plate 21 on one side of the first cylinder 20 and connect the connecting plate 21 to the pneumatic rod of the first cylinder 20. Then, the feeding plate 22 can be installed on one side of the connecting plate 21. The feeding plate 22 has two groups of through holes. The user can clamp the two groups of feeding ports 23 in the two groups of through holes opened in the feeding plate 22, and can connect the feeding port 23 to the discharge port 16 through a hose. When the mechanism performs the feeding operation, the two sets of springs can be smoothly transported from the two sets of discharge ports 16 through the two sets of hoses and into the two sets of feeding ports 23. Then the first cylinder 20 works, and the pneumatic rod of the first cylinder 20 pushes downward, with the feeding plate 22 and the feeding port 23 moving downward, so that the two sets of springs enter the feeding tray groove 271 on the uniformly rotating feeding tray 27 from the two sets of feeding ports 23. After the feeding action is completed, the pneumatic rod of the first cylinder 20 is reset and waits for the next feeding action.

[0030] Among them, see Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the user can install the second cylinder 25 to the end of the fixed bracket 24 close to the movable table 10. The positioning assembly includes a positioning pin 26. The positioning pin 26 is set at one end of the second cylinder 25. The pneumatic rod of the second cylinder 25 is connected to the positioning pin 26. When the pneumatic rod of the second cylinder 25 moves, the positioning pin 26 will also move accordingly. A plurality of groups of material tray positioning grooves 272 are provided on the side of the uniformly rotating material tray 27. The hole diameter of the positioning groove 272 is the same as the diameter of the positioning pin 26. The positioning pin 26 can be inserted into the positioning groove 272. , one group of tray positioning grooves 272 corresponds to the positioning pin 26, the positioning assembly also includes a positioning bracket 28 and a tension spring 29, a positioning bracket 28 is provided on one side of the uniformly rotating tray 27, the user can install the positioning bracket 28 on the base 11 by screws, and the positioning bracket 28 is fixed, and a tension spring 29 is provided on the side of the positioning bracket 28 close to the fixed bracket 24, the user can connect the tension spring 29 to the fixed bracket 24, so that when the fixed bracket 24 is rotated, it can be reset by the tension of the tension spring 29.

[0031] The bottom of the tray main shaft 30 is rotatably connected to the base 11, and a semicircular bearing 31 is sleeved on the tray main shaft 30. The end of the fixed bracket 24 close to the tray main shaft 30 is fixedly connected to the semicircular bearing 31, so that the fixed bracket 24 does not rotate synchronously with the rotation of the tray main shaft 30. A fixing ring 32 is provided on the top of the semicircular bearing 31, and the fixing ring 32 is sleeved on the tray main shaft 30.

[0032] When the feeding action is performed, the pneumatic rod of the second cylinder 25 extends outward, thereby causing the positioning pin 26 to extend synchronously. When the positioning pin 26 extends, it will be stuck in one of the positioning grooves 272 of the group, so that the fixed bracket 24 rotates synchronously with the uniformly rotating material disc 27, ensuring that the feeding port 23 is always accurately aligned with the material disc groove 271 at the top of the uniformly rotating material disc 27, and the feeding action is performed in this process. After the feeding is completed, the second cylinder 25 stops working and the pneumatic rod is reset, so that the positioning pin 26 is pulled out of the positioning groove 272, and the fixed bracket 24 no longer rotates synchronously with the uniformly rotating material disc 27. At the same time, the fixed bracket 24 will be reset under the action of the tension of the tension spring 29, waiting for the next feeding action, effectively improving the feeding accuracy, avoiding the problem that the feeding time will be caused by various factors and the feeding time and the turntable speed are difficult to match, and the spring will often not be thrown into the material disc groove 271. The feeding process is automatic and does not rely on manual operation.

[0033] Among them, see Figure 2 、 Figure 3 and Figure 4 As shown, the user can install the support bracket 19 on the top of the movable table 10 and fix the support bracket 19 with screws. A connecting bracket 18 is provided on the top of the support bracket 19. Two groups of through grooves 181 are opened at one end of the connecting bracket 18 close to the main shaft 30 of the material tray. These two groups of through grooves 181 are used to pass through the hoses connecting the feeding port 23 and the discharging port 16. The user can connect one end of the two groups of hoses to the two groups of discharging ports 16 respectively, and then pass the other ends of the two groups of hoses through the two groups of through grooves 181 respectively, and connect the other ends of the two groups of hoses to the two groups of feeding ports 23 respectively. A track bracket 17 is installed on the top of the connecting bracket 18. The user can install the queuing double track 14 on the top of the track bracket 17, and the end of the queuing double track 14 close to the main shaft 30 of the material tray is connected to the discharging mechanism 15, and the two groups of spring outlets 13 are connected at one end of the queuing double track 14 close to the vibration plate 12.

[0034] Among them, see Figure 1 、 Figure 2 and Figure 3 As shown, a collecting mechanism 33 is provided on the top of the uniformly rotating material tray 27, and the bottom of the collecting mechanism 33 is connected to the base 11. After the feeding port 23 feeds two groups of springs into the material tray slot 271 on the top of the uniformly rotating material tray 27, the uniformly rotating material tray 27 continues to rotate driven by the material tray main shaft 30. Then, when the two groups of material tray slots 271 containing two groups of springs pass through the collecting mechanism 33, the collecting mechanism 33 takes out the two groups of springs in the two groups of material tray slots 271 and collects the two groups of springs. Then the user can collect the springs.

[0035] Among them, see Figure 2 and Figure 3As shown, a power module 34 is provided on one side of the movable table 10. When the user connects an external power source to the structure, the structure can be started to work through the power module 34. Two sets of vibration feeding controllers 35 are provided on one end of the power module 34 close to the material tray main shaft 30. One side of the two sets of vibration feeding controllers 35 are connected to the movable table 10. The user can install these two sets of vibration feeding controllers 35 on one side of the movable table 10. These vibration feeding controllers 35 are electrically connected to the vibration disk 12. The user can control the discharge speed of the vibration disk 12 through the vibration feeding controller 35, and the panel of the vibration feeding controller 35 is provided with buttons, knobs and other keys, which are convenient for users to directly operate it, thereby improving convenience.

[0036] Among them, see Figure 1 and Figure 5 As shown, multiple sets of universal wheels 36 are provided at the bottom of the mobile table 10. Through the setting of the universal wheels 36, the user can easily push the mobile table 10 to shift, and conveniently adjust the distance or angle between the mobile table 10 and the base 11. An inspection door 37 is provided on one side of the mobile table 10. The user can open the inspection door 37 to inspect or maintain the circuit of the vibration feeding controller 35 or the vibration disk 12 buried in the mobile table 10, and the inspection door 37 can prevent dust from entering the interior of the mobile table 10, preventing the circuit of the vibration feeding controller 35 or the vibration disk 12 buried in the mobile table 10 from being affected by dust and aging too quickly, thereby extending the service life of the vibration feeding controller 35 or the vibration disk 12.

[0037] The specific usage and function of this embodiment: When the structure is used, the structure is powered by an external power supply. The user can connect the two groups of discharge ports 16 with the two groups of feeding ports 23 through two sets of hoses, connect one end of the two groups of hoses to the two groups of discharge ports 16 respectively, and then pass the other ends of the two groups of hoses through the two groups of through slots 181 respectively, and connect the other ends of the two groups of hoses to the two groups of feeding ports 23 respectively, so that the spring can be smoothly transported from the discharge port 16 to the feeding port 23, and then the structure can be started through the power module 34. After the structure is started, the user can control the discharge speed of the vibration plate 12 through the vibration feeding controller 35, and the vibration feeding controller 35 panel is provided with buttons, knobs and other buttons, which are convenient for users to operate directly, thereby improving convenience. When the ground spring enters the vibration plate 12, the vibration of the vibration plate 12 vibrates to transport the spring from the spring outlet 13 to the queue double track 14. The spring enters the discharge mechanism 15 through the queue double track 14, and passes through the discharge mechanism 15 so that the spring can enter the discharge port 16, and then the spring is discharged from the discharge port. The feed port 16 enters into the hose, and the spring enters into the feed port 23 through the hose. At this time, the positioning assembly works, and the pneumatic rod of the second cylinder 25 extends forward, thereby driving the positioning pin 26 to extend forward and snap into the matching positioning groove 272, so that the fixed bracket 24 and the uniformly rotating material tray 27 rotate in the same direction and at a uniform speed, and the tension spring 29 is stretched to ensure that the feed port 23 is always accurately aligned with the material tray groove 271. In this process, accurate feeding can be performed. At the same time, the feeding assembly works, the first cylinder 20 is started, and the pneumatic rod moves downward. The first cylinder 20 moves, driving the feeding plate 22 to move downward synchronously, so that the spring can accurately feed the material from the feeding port 23 to the matching material tray slot 271. When the feeding is completed, the pneumatic rod of the first cylinder 20 is reset, driving the feeding plate 22 and the feeding port 23 to reset, and the second cylinder 25 is also reset, and the positioning pin 26 is pulled out of the positioning slot 272, so that the fixed bracket 24 no longer rotates synchronously with the uniformly rotating material tray 27. At this time, the tension spring 29 is reset, thereby driving the fixed bracket 24 to reset, so that the feeding assembly can perform the next feeding action.
