[0029] Reference Figures 1-6 A feeding pallet assembly structure includes a pallet base 11. A front sliding block power gearbox 51 and a rear sliding block power gearbox 52 are mounted side by side at the rear end of the pallet base 11. Both gearboxes include three gears 53 arranged side by side with the same number of teeth. The three gears 53 mesh with each other. The middle gear 53 acts as an idler gear to transmit motion and power. The two side gears 53 are driven by a motor 54 and a handle 55 respectively.

[0030] The front sliding block 21 and the rear sliding block 22 are slidably installed side by side on the tray base 11.

[0031] The bottom of the front sliding block 21 is fixed with two front sliding block nut seats 31 arranged side by side. The two front sliding block nut seats 31 are threadedly connected to the two front sliding block power screws 41 arranged side by side. The two front sliding block power screws 41 are connected to the two side gears 53 on the front sliding block power gearbox 51.

[0032] The bottom of the rear sliding block 22 is fixed with two rear sliding block nut seats 32 arranged side by side. The two rear sliding block nut seats 32 are threadedly connected to the two rear sliding block power screws 42 arranged side by side. The two rear sliding block power screws 42 are connected to the two side gears 53 on the rear sliding block power gearbox 52.

[0033] Two or more bearings 92 are provided between the front sliding block power screw 41, the rear sliding block power screw 42 and the support plate seat 11 to reduce friction and make the movement smoother and more stable.

[0034] In use, if the front sliding block 21 is to be driven to move forward or backward in a straight line, the motor 54 or handle 55 in the front sliding block power gearbox 51 can be used to drive one of the corresponding side gears 53 to rotate. Then, the middle gear 53 is used as an idler to transmit motion and power to the other side gear 53. When the three gears rotate synchronously, the two front sliding block power screws 41 rotate synchronously, and the two front sliding block nut seats 31 drive the front sliding block 21 to move forward or backward in a straight line.

[0035] If you want to drive the rear slider 22 to move forward or backward, you can use the same method described above.

[0036] The front sliding block 21 and the rear sliding block 22 can move independently or simultaneously. Thus, a motor can be installed on each of the front sliding block 21 and the rear sliding block 22. The shaft of the rear motor can pass through the hollow shaft of the front motor. This allows for independent control of the front and rear sliding blocks of the two motors on the same axis, or for the two motors to drive the two grinding wheels to work independently or synchronously. The above structural design can reduce the number of motors installed along the length of the machine tool, thereby reducing the overall length of the machine tool.

[0037] This application employs a double lead screw, double sliding block, and double power gearbox. The lead screw is arranged in upper and lower layers, and the sliding block is arranged in front and rear layers. This ensures the balance and support of the sliding block, making the forward and backward movement smooth and the support stable, greatly improving the shock resistance and guaranteeing the quality of edge grinding. The use of double sliding blocks, arranged in front and rear layers, allows for the placement of one motor at each end, enabling independent control of the front and rear sliding blocks of the two motors on the same axis, while also reducing the overall size.

[0038] In some embodiments, the pallet seat 11 has two front nut seat grooves 61 and two rear nut seat grooves 62 arranged side by side. The two front sliding block nut seats 31 and the two rear sliding block nut seats 32 are respectively installed in the two front nut seat grooves 61 and the two rear nut seat grooves 62, and can move back and forth. Its structure is compact and occupies little space, which further ensures the balance and support of the sliding block, making it smooth in and out and stable in support.

[0039] In some embodiments, two front sliding block power screws 41 and two rear sliding block power screws 42 are arranged side by side, one above the other. The rear ends of the two front sliding block power screws 41 pass through the through holes on the two rear sliding block nut seats 32 and the through holes at the rear end of the support plate seat 11 in sequence. The rear ends of the two rear sliding block power screws 42 pass through the through holes at the rear end of the support plate seat 11. The above design allows the two front sliding block power screws 41 and the two rear sliding block power screws 42 to work independently without affecting each other.

[0040] In some embodiments, the motor 54 on the front sliding block power gearbox 51 and the motor 54 on the rear sliding block power gearbox 52 are staggered vertically. This avoids the problem of occupying too much space when the two motors 54 are arranged vertically or horizontally side by side. At the same time, it makes it more convenient to turn the handle 55. Both handles 55 are equipped with handle wheels, making it easy and effortless to turn.

[0041] In some embodiments, the rear sliding block 22 between the front sliding blocks 21 is provided with a concave-convex interlocking clearance structure, which includes a protrusion 71 and a groove 81 that matches the protrusion 71; the above design ensures that the center of gravity of the force support point on each sliding block does not shift when the motor or motor mount mounted on the two sliding blocks is brought as close as possible.

[0042] In some embodiments, both the front sliding block power gearbox 51 and the rear sliding block power gearbox 52 include a housing 91, and bearings 92 are installed at both ends of each gear 53 to improve the stability of the support and reduce resistance. The gears 53 and bearings 92 are located inside the housing 91 to prevent or reduce dust from entering.

[0043] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the claims and their equivalents.
