[0023] Furthermore, the discharge assembly 30 of this embodiment further includes a plurality of transition rollers 34, which are arranged on the base 20 in the front-to-back direction. The tabs discharged from the tray 33 sequentially pass through the plurality of transition rollers 34 and slide on the transition rollers 34. Under the tension of the transition rollers 34, the tabs can be made flatter during the transfer process.

[0024] Please continue reading Figure 1-Figure 3 The tab feeding mechanism 100 of the tablet making machine in this embodiment further includes a leveling assembly 40. The tab is fed to the leveling assembly 40 by the discharge assembly 30. The leveling assembly 40 makes the tab more flat during transport. Specifically, the leveling assembly 40 includes a first roller 41, a second roller 42, and a third roller 43. The first roller 41, the second roller 42, and the third roller 43 are all fixed to the base 20.

The distance between the center point of the first roller 41 and the center point of the third roller 43 is equal to the distance between the center point of the second roller 42 and the center point of the third roller 43. The leveling assembly 40 is a preferred choice in this embodiment, but is not limited thereto. As long as rollers are provided above and below the tab, it will suffice.

[0025] Please continue reading Figure 1-Figure 3 The tab feeding mechanism 100 of the tablet making machine in this embodiment also includes a placement plate 40a, a feeding assembly 50, a pressing assembly 60, a cutting assembly, and a return clamp 70a. The tab is fed by the leveling assembly 40 onto the horizontal placement plate 40a. The feeding assembly 50 is connected to the placement plate 40a, and the pressing assembly 60 is located above the placement plate 40a. The tab is then fed from the placement plate 40a to the cutter 71 of the cutting assembly, and the return clamp 70a is located in front of the cutting assembly. The pressing assembly 60 presses the tab on the placement plate 40a from above, the feeding assembly 50 pushes the placement plate 40a forward to a certain position, the return clamp 70a secures the front end of the tab, and the cutting assembly cuts the front end of the tab.

[0026] Please continue reading Figure 1-Figure 3The tablet production machine tab feeding mechanism 100 of this embodiment further includes an adjustment assembly 80, with two return clamps 70a, each of which is separated by a distance.

One return clamp 70a is fixed to the first slider 82, and the other return clamp 70a is fixed to the second slider. When the tab is fed to the return clamp 70a, the tab is clamped between the two return clamps 70a. The distance between the two return clamps 70a is adjusted by adjusting the distance between the first slider 82 and the second slider.

[0027] The structures of the above components are described in detail below:

[0028] Furthermore, the feeding assembly 50 of this embodiment includes a second rotary driver 51, a first screw rod 52, a first nut 53, a third slider 54, and a guide rail 55. The second rotary driver 51 and the guide rail 55 are both arranged on the base 20 in the left-right direction. The first screw rod 52 is arranged in the left-right direction and connected to the output end of the second rotary driver 51. The first nut 53 is sleeved on the first screw rod 52. The third slider 54 and the placement plate 40a are both connected to the first nut 53. The third slider 54 slides on the guide rail 55. Then, the second rotary driver 51 drives the first screw rod 52 to rotate, the first nut 53 moves along the length of the first screw rod 52, and the third slider 54 and the placement plate 40a both move in the left-right direction, thereby moving the tab placed on the placement plate 40a forward.

[0029] The clamping assembly 60 of this embodiment includes a first linear actuator 61 and a pressure plate 62. The first linear actuator 61 is vertically disposed on the placement plate 40a, and the pressure plate 62 is located below the first linear actuator 61. The pressure plate 62 is fixed to the output end of the first linear actuator 61. Therefore, the first linear actuator 61 drives the pressure plate 62 downward, and the pressure plate 62 fixes the tab from above.

[0030] Furthermore, the cutting assembly of this embodiment includes a cutter 71 and a second linear actuator 72. The second linear actuator 72 is vertically mounted on the base 20. The cutter 71 is connected to the output end of the second linear actuator 72 and positioned between the alignment clamp 70a and the discharge end of the placement plate 40a. The second linear actuator 72 drives the cutter 71 to move vertically up and down, thereby severing the front end of the tab.

[0031] Furthermore, the tableting machine feeding lug mechanism 100 of this embodiment also includes a cutter angle correction assembly 90, which includes an adjustment seat 91, a rotating shaft 92 and a fixing screw 93. The rotating shaft 92 is arranged in the vertical direction, and the adjustment seat 91 rotates around the rotating shaft 92. The base 20 includes a sliding groove, and the fixing screw 93 is adjusted in the sliding groove; when the fixing screw 93 is adjusted to the appropriate position, the fixing screw 93 fixes the adjustment seat 91 to the base 20. The angle of the cutter 71 can be adjusted by rotating the adjustment seat 91.

[0032] Please continue reading Figure 1-Figure 3 The tab feeding mechanism 100 of the tablet making machine in this embodiment further includes a tab cutter stripping assembly 90a, which pushes the base 20 to slide left and right on the frame 10. Specifically, the tab cutter stripping assembly 90a includes a third rotary driver 91a, a second screw rod 92a, and a second nut 93a. The third rotary driver 91a is disposed on the frame 10 in the left and right direction. The second screw rod 92a is connected to the third rotary driver 91a. The second nut 93a is sleeved on the second screw rod 92a. The base 20 is fixed to the second nut 93a. Therefore, when the third rotary driver 91a rotates, it drives the second nut 93a to move left and right along the second screw rod 92a, thereby driving the base 20 to move. After welding the tabs once, some tabs are too long. To ensure that each tab is the same length, the excess waste needs to be cut off. The tab cutter stripper assembly 90a moves the placement plate 40a back a certain distance, cuts off the waste, and then moves the tab forward to the welding position. The purpose of moving back is to avoid cutting the waste too close to the tab, which would cause the cut waste to fly onto the tab and cause poor welding.

[0033] Compared with the prior art, the present invention has the following beneficial effects: the tab feeding mechanism 100 of the tableting machine of this embodiment transports the tab to the cutting position through the discharge assembly 30, the leveling assembly 40, and the feeding assembly 50, fixes the rear end of the tab by the clamping assembly 60, and fixes the front end of the tab by the straightening clamp 70a. After the tab is fixed, the front end of the tab is cut off by the cutting assembly; the tab feeding mechanism 100 of the tableting machine clamps the tab in front of the cutter 71, and the position of the tab does not move after the tab is cut off. The tab is welded to the electrode sheet at the original position, and the tab does not make any displacement action, thereby ensuring the accuracy of the welding spacing between the tab and the electrode sheet.
