DETAILED DESCRIPTION

[0017] See also Figure 1-Figure 3 , a feeding device for spacer processing, comprising a side plate 1, a roller 2, a conveyor belt 3 and a driving device, the side plate 1 is arranged front and back, the roller 2 has a pair and is rotatably connected to the left and right sides between the side plates 1, the conveyor belt 3 is connected between the rollers 2, the driving device is installed on the surface of the side plate 1, the driving device comprises a motor 4, a synchronous wheel 5 and a synchronous belt 6, the motor 4 is fixedly installed on the left part of the rear end of the side plate 1 on the rear side, the front part of the roller 2 passes through the side plate 1 on the front side, the synchronous wheel 5 has a pair and is fixed to the front part of the roller 2 in a one-to-one correspondence, the synchronous belt 6 is connected between the synchronous wheels 5, the output end of the motor 4 is connected to one of the rollers 2, when the motor 4 is started, the motor 4 drives one of the rollers 2 to rotate, and the roller 2 drives the corresponding synchronous wheel 5 to rotate, because the synchronous wheels 5 rotate synchronously through the synchronous belt 6, so the two rollers 2 can rotate synchronously, at this time, the two rollers 2 drive the conveyor belt 3 to move, so that the spacer is placed on the conveyor belt 3 to transport and feed the spacer;

[0018] The front and rear sides of the upper end of the conveyor belt 3 are slidably connected with clamping plates 7, and the ends of the clamping plates 7 that are away from each other are fixed with a ruler 9, and the upper ends of the side plates 1 are fixed with a fixing seat 8, and the ends of the ruler 9 are movably penetrated with the fixing seat 8, and a cross bar 10 is fixed to the end of the ruler 9, and an L-shaped rod 11 is vertically fixed to the end of the cross bar 10, and a gear box 13 is fixed between the middle parts of the lower ends of the side plates 1, and the end of the L-shaped rod 11 penetrates into the interior of the gear box 13 and is slidably connected to the gear box 13, and a pair of through holes 12 are opened at the front and rear ends of the gear box 13, and the L-shaped rod 11 is interspersed with the through holes 12, and a gear rack assembly is installed between the ends of the L-shaped rod 11, and the gear rack assembly includes a rotating shaft 15, a gear 16 and a rack 18, and the rotating shaft 15 bearing is connected to the middle of the gear box 13, and the gear 16 is fixed to the outside of the rotating shaft 15, and the rack 18 has a pair of and is symmetrically meshed and connected to the left and right sides of the gear 16, and the rack 18 is connected to the same side The end of the L-shaped rod 11 is fixed, and the spacer will be located between the clamping plates 7 when conveying and loading materials on the conveyor belt 3. In this way, when it is necessary to adjust the clamping plates 7 to a suitable spacing to prevent the spacer from shifting, it is only necessary to push one of the clamping plates 7, and the clamping plate 7 will drive the ruler 9, the cross bar 10, and the L-shaped rod 11 to move synchronously. The ruler 9 slides along the fixed seat 8, and it is convenient to understand how much the clamping plate 7 has moved against the scale on the ruler 9. As the L-shaped rod 11 slides into the gear box 13, the L-shaped rod 11 drives one of the racks 18 to move. At this time, the rack 18 drives the gear 16 to rotate, and the gear 16 drives the other rack 18 to move in the opposite direction. The other rack 18 drives the other clamping plate 7 to move synchronously through the ruler 9, the cross bar 10, and the L-shaped rod 11. In this way, the two clamping plates 7 can move at the same time, but in opposite directions. Therefore, one person can also adjust the spacing between the clamping plates 7, which is convenient to operate, so that the clamping plate 7 can well transport and load the spacer in an orderly manner.

[0019] Two groups of ratchet pawl assemblies are symmetrically installed at the upper and lower ends of the inner wall of the gear box 13, and the gear rack assembly is connected to the ratchet pawl assembly. The ratchet pawl assembly includes a ratchet box 17, a ratchet 20, a pawl 21 and a spring 22. The ratchet box 17 is fixed to the inner wall of the gear box 13, and the two ends of the rotating shaft 15 respectively penetrate into the upper and lower ratchet boxes 17. The ratchet 20 is located inside the ratchet box 17 and fixed outside the rotating shaft 15. The pawl 21 is located in front of the ratchet 20 and is rotatably connected to the inside of the ratchet box 17. The pawl 21 is connected to the ratchet 20, and the spring 22 is connected between the front end of the pawl 21 and the front end of the ratchet box 17. When the gear 16 rotates, the shaft 15 is driven to rotate, and the shaft 15 drives the two ratchet wheels 20 to rotate at the same time. One of the pawls 21 can prevent the corresponding ratchet wheel 20 from rotating clockwise, and the other pawl 21 can prevent the other ratchet wheel 20 from rotating counterclockwise. In this way, when the two pawls 21 are connected to the two ratchet wheels 20 at the same time, the shaft 15 can be prevented from rotating, thereby preventing the gear 16 from rotating;

[0020] A pull rope 19 is fixed to the front end of the pawl 21, and the pull rope 19 is located on the inner side of the spring 22. The end of the pull rope 19 passes through the front end of the ratchet box 17 and the front end of the gear box 13 in sequence. A pull head 14 is fixed to the end of the pull rope 19. When it is necessary to shorten the spacing between the clamping plates 7, the upper pull head 14 is pulled, and the upper pull head 14 pulls the upper pull rope 19. The upper pull rope 19 pulls the upper pawl 21 to rotate and separate from the upper ratchet 20. The upper pawl 21 will squeeze the upper spring 22. At this time, the upper pawl 21 no longer hinders the upper ratchet 20 from rotating clockwise. In this way, pushing the clamping plates 7 to close the spacing can make the gear 16 rotate clockwise. When it is necessary to pull the clamping plates 7 apart to adjust the spacing When the distance is between the upper and lower parts, the pull head 14 on the lower side is pulled to release the pull head 14 on the upper side. At this time, the spring 22 on the upper side will reset and push the upper pawl 21 to connect with the ratchet 20 on the upper side. The pull head 14 on the lower side pulls the pull rope 19 on the lower side. The pull rope 19 on the lower side pulls the lower pawl 21 on the lower side to rotate and separate from the ratchet 20 on the lower side. At this time, the lower pawl 21 no longer hinders the counterclockwise rotation of the ratchet 20 on the lower side. In this way, pulling the clamping plate 7 to open the distance can make the gear 16 rotate counterclockwise. In this way, it is only necessary to make the corresponding pawl 21 no longer connected with the corresponding ratchet 20, and the gear 16 can rotate in one direction, so as to achieve the unidirectional movement of the clamping plate 7. After moving the clamping plate 7, it is also convenient to limit the clamping plate 7, thereby improving practicality.

[0021] Working principle: Place the spacer on the conveyor belt 3 and between the clamping plates 7, then push one of the clamping plates 7, the clamping plate 7 will drive the ruler 9, the cross bar 10, and the L-shaped rod 11 to move synchronously, so that the L-shaped rod 11 drives one of the racks 18 to move, and at this time the rack 18 will drive the gear 16 to rotate, and the gear 16 drives the other rack 18 to move in the opposite direction, and the other rack 18 drives the other clamping plate 7 to move synchronously through the ruler 9, the cross bar 10, and the L-shaped rod 11. After the spacing between the clamping plates 7 is adjusted, the motor 4 is started, and the motor 4 drives one of the rollers 2 to rotate, and the roller 2 drives the corresponding synchronous wheel 5 to rotate. Because the synchronous wheels 5 rotate synchronously through the synchronous belt 6, the two rollers 2 can rotate synchronously. At this time, the two rollers 2 drive the conveyor belt 3 to move, so that the spacer is placed on the conveyor belt 3 to transport and load the spacer.
