DETAILED DESCRIPTION

[0020] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0021] like Figure 1-3 As shown, the utility model provides a technical solution: a feeding device for CNC machine tool processing, comprising a base 1, three groups of conveying rollers 2 are equidistantly mounted on the inner wall of the base 1, and conveying gears 3 are fixedly mounted on both ends of the conveying rollers 2 located on the inner side of the base 1, and conveying chains 4 are arranged on the surfaces of the three groups of conveying gears 3 located on the same side of the base 1. A cushion block 5 is fixedly mounted on the bottom of the base 1 between the two groups of conveying rollers 2. Because the cushion block 5 is provided, the cushion block 5 can support one end of the plate passing through the conveying roller 2 to prevent the plate from falling after passing through one end of the conveying roller 2;

[0022] A conveying motor 6 is fixedly installed at one end of the outer side of the base 1, and one end of a group of conveying rollers 2 passes through the base 1 and is fixedly connected to the conveying motor 6. By providing a conveying chain 4, the conveying motor 6 is started to drive a group of conveying rollers 2 to rotate, so that the conveying gear 3 is meshed and transmitted inside the conveying chain 4, and the rotation is transmitted to the conveying gears 3 on the same side of the three groups of conveying rollers 2, so that the three groups of conveying rollers 2 can rotate synchronously.

[0023] Mounting frames 7 are fixedly installed at both ends of one side of the base 1, and a slide groove 8 is provided on the inner wall of the mounting frame 7. A door panel 9 is slidably installed inside the slide groove 8 between the two sets of mounting frames 7. Because of the provision of the door panel 9, after the door panel 9 is covered on one side of the base 1 and the side panel 10, the plate on the top of the conveying roller 2 is resisted and supported to ensure that the plate does not move to the side away from the baffle 19 at the top of the conveying roller 2 and fall.

[0024] Side panels 10 are fixedly installed on both sides of the top of the base 1, and three groups of mounting columns 11 are fixedly installed at equal intervals on the surface of the side panels 10, and a clamping plate 12 is slidably installed on the surface of the six groups of mounting columns 11 located between the two groups of side panels 10. A clamping spring 13 is provided on the surface of the mounting column 11 located on the top of the clamping plate 12. By providing the clamping spring 13 and the clamping plate 12, the clamping plate 12 is pressed toward the conveying roller 2 under the rebound action of the clamping spring 13, so that the plate is clamped between the conveying roller 2 and the clamping plate 12, preventing the plate from shaking up and down away from the conveying roller 2 when moving on the top of the conveying roller 2.

[0025] A fixed plate 14 is fixedly installed between the central positions of the two groups of side plates 10 away from the mounting frame 7; limited sliding rods 15 are symmetrically slidably installed on both sides of the fixed plate 14, and a bottom plate 16 is fixedly installed at the bottom ends of the two groups of limited sliding rods 15; a limited groove 17 is provided on the side of the side plate 10 away from the mounting frame 7, and limited sliding blocks 18 are fixedly installed at both ends of the bottom plate 16, and the limited sliding blocks 18 correspond to the limited grooves 17. Because the limited sliding rods 15 and the limited sliding blocks 18 are provided, when the bottom plate 16 is adjusted to move up and down, the limited sliding rods 15 slide up and down on both sides of the fixed plate 14, and the limited sliding blocks 18 slide inside the limited grooves 17, ensuring that there is no tilting deflection between the bottom plate 16 and the fixed plate 14;

[0026] A baffle 19 is fixedly installed on one side of the bottom plate 16 located between the two groups of side plates 10, and a top plate 20 is fixedly installed on the top ends of the two groups of limiting slide bars 15 through the fixed plate 14. An adjusting stud 21 is fixedly installed at the central position between the bottom plate 16 and the top plate 20, and the adjusting stud 21 passes through the two side surfaces of the fixed plate 14 and is provided with an adjusting screw sleeve 22. By providing the adjusting screw sleeve 22, the adjusting screw sleeve 22 is screwed away from the fixed plate 14, so as to facilitate the adjustment of the distance between the bottom plate 16 and the baffle 19 and the conveying roller 2, ensuring that only one plate can pass through the distance between the bottom plate 16 and the conveying roller 2 at a time, and the excess plate is blocked by the baffle 19 at the top of the conveying roller 2 between the two groups of side plates 10.

[0027] The working principle of the utility model is:

[0028] After lifting the door panel 9 downward away from the base 1, pull the clamping plate 12 away from the conveying roller 2, insert the stacked plates between the conveying roller 2 and the clamping plate 12, until the plates are completely inserted between the two sets of side plates 10, release the clamping plate 12 and press the clamping plate 12 downward under the rebound action of the clamping spring 13, so that the plates are pressed between the conveying roller 2 and the clamping plate 12, push the door panel 9 to cover one side of the plates, loosen the adjusting screw sleeve 22, lift the top plate 20 upward to drive the bottom plate 16 and the baffle 19 to move upward, control the distance between the bottom plate 16 and the conveying roller 2 according to the thickness of the plates to accommodate a plate passing through, tighten the adjusting screw sleeve 22, start the conveying motor 6 to control the three sets of conveying rollers 2 to rotate synchronously, and under the friction between the conveying roller 2 and the plates, the plates can pass through the bottom plate 16 to the CNC machine tool.
