Technical Field

[0001] The invention relates to the field of bamboo skewer processing, and in particular to a bamboo skewer processing burr removal device. Background Art

[0002] After the bamboo sticks are prepared, there are often many burrs on their surface. If used carelessly, it is very easy to prick your fingers. Therefore, after the bamboo sticks are prepared, the burrs on their surface need to be polished and eliminated.

[0003] At present, when removing burrs from the surface of bamboo sticks, a common method is to let the bamboo sticks move on a conveyor belt, and then make the bamboo sticks and the grinding belt rotate relative to each other when passing through a grinding device, so as to grind them. However, a defect of this method is that the bamboo sticks may not be able to completely cause the axis to rotate one circle as the rotation center during the process of passing through the grinding device, resulting in incomplete grinding of the bamboo sticks, and there will still be certain burrs, thus affecting the quality of the product. For this reason, this scheme proposes a bamboo stick processing burr removal device. Summary of the invention

DETAILED DESCRIPTION

[0038] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0039] Embodiment 1:

[0040] Please combine Figure 1 - Figure 5 , a bamboo skewer processing burr removal device of this embodiment includes:

[0041] A feeding mechanism comprises a conveyor belt 1 and a hopper 2 arranged directly above the conveyor belt 1. The outer surface of the conveyor belt 1 is evenly provided with placement grooves arranged along its width direction. The hopper 2 is composed of a trapezoidal frame and a rectangular frame fixed on the top of the trapezoidal frame. The trapezoidal frame is a structure that is wide at the top and narrow at the bottom, and a discharge port arranged along the length direction of the placement groove is opened at the bottom of the trapezoidal frame, and the length of the discharge port is less than the length of the placement groove. The width of the discharge port is 1.2-1.3 times the diameter of the bamboo stick, and the length of the discharge port is 1.1-1.2 times the length of the bamboo stick. The distance between the discharge port and the conveyor belt 1 is greater than the radius of the bamboo stick but less than the diameter of the bamboo stick. The placement groove is a semicircular structure. When working, the bamboo sticks to be processed are stored in the hopper 2. Under the action of gravity, the bamboo sticks in the hopper 2 will be discharged from the discharge port in sequence and fall on the conveyor belt 1. Then, they will fall into the placement groove under the rotation of the conveyor belt 1, and then be transported to the position of the grinding mechanism as the conveyor belt 1 rotates.

[0042] The grinding mechanism includes a mounting platform 3 arranged on one side of the conveyor belt 1, a top plate 12 fixed on the top surface of the mounting platform 3 and a grinding assembly arranged on the other side of the conveyor belt 1, the top plate 12 is located directly above the conveyor belt 1, and the grinding assembly includes a conical guide cylinder 15 and a grinding ring 21 fixed on the end of the guide cylinder 15 with a small opening, the guide cylinder 15 is connected to the top plate 12 through a connecting piece, the end of the guide cylinder 15 with a large opening faces the conveyor belt 1, and the axial direction of the guide cylinder 15 is consistent with the length direction of the placement groove, the conveyor belt 1 rotates intermittently, when the placement groove moves with the bamboo stick to a position coincident with the axis of the guide cylinder 15, the bamboo stick is pushed into the guide cylinder 15, and in the process of the bamboo stick passing through the guide cylinder 15 and the grinding ring 21, the grinding ring 21 can grind the burrs on the outer surface of the bamboo stick clean.

[0043] The pushing mechanism includes a telescopic member 4 installed on the top surface of the mounting table 3, a push plate 5 fixed at the output end of the telescopic member 4 and a push rod 6 fixed on the outer wall of the push plate 5 on the side close to the conveyor belt 1. The push rod 6 is coaxially arranged with the guide cylinder 15. The telescopic member 4 is an electric telescopic rod. When the bamboo stick moves to a position coincident with the axis of the guide cylinder 15, the telescopic member 4 extends, thereby driving the push plate 5 and the push rod 6 to approach the side of the conveyor belt 1. After the push rod 6 enters the placement groove, the bamboo stick in the placement groove can be pushed into the guide cylinder 15, so that the bamboo stick can pass through the grinding ring 21 under the action of the thrust.

[0044] The material guiding mechanism is installed on the side of the guide cylinder 15 away from the conveyor belt 1 and is used to draw the bamboo sticks out of the guide cylinder 15. The material guiding mechanism includes a mounting plate 17 fixed to the bottom surface of the top plate 12 and two guide rollers 16 rotatably connected to the outer wall of the mounting plate 17. A gap is provided between the two guide rollers 16, and the size of the gap is the same as the inner diameter of the grinding ring 21. A motor for driving the guide rollers 16 to rotate is installed on the mounting plate 17. After the bamboo stick passes through the guide cylinder 15 and is polished by the grinding ring 21, it will enter between the two guide rollers 16. After the two guide rollers 16 rotate towards each other, they can apply an outward pulling force to the bamboo stick, thereby helping the bamboo stick to pass through the guide cylinder 15 and the grinding ring better. After the push rod 6 is out of contact with the bamboo stick, the guide roller 16 can continue to completely draw the bamboo stick out of the guide cylinder 15, so that the entire bamboo stick is completely polished.

[0045] A material pressing mechanism is installed on the bottom surface of the top plate 12, and the material pressing mechanism includes a telescopic column installed on the bottom surface of the top plate 12 and a pressing plate 10 fixed at the bottom of the telescopic column. The pressing plate 10 is located directly above the conveyor belt 1, and the telescopic column includes a movable column 14 fixed on the top surface of the pressing plate 10 and a fixed cylinder 11 movably sleeved on the outer periphery of the top of the movable column 14. The top of the fixed cylinder 11 is fixedly connected to the bottom surface of the top plate 12, and a locking bolt 20 is screwed on the outer periphery of the fixed cylinder 11. One end of the locking bolt 20 abuts against the outer wall of the movable column 14, and the pressing plate is pressed on the top surface of the bamboo stick, thereby preventing the push rod 6 from bending upward during the process of pushing the bamboo stick into the guide cylinder 15. The setting of the telescopic column can facilitate the adjustment of the height of the pressing plate 10. When adjusting the length of the telescopic column, loosen the locking bolt 20, and then the movable column 14 can be moved up and down. After the adjustment is completed, tighten the locking bolt 20.

[0046] A cleaning mechanism is provided at one side of the conveyor belt 1 and is used to remove bamboo chips on the grinding ring 21. The cleaning mechanism comprises an air cylinder 18 fixed to the bottom surface of the top plate 12, a piston plate provided in the air cylinder 18, and an air inlet pipe and an air jet pipe 19 installed on the air cylinder 18. Both the air inlet pipe and the air jet pipe 19 are provided with a one-way valve, and the outlet of the air jet pipe 19 faces the grinding ring 21. A linkage mechanism for driving the piston plate to move is installed on the top surface of the mounting platform 3. After grinding is completed, the piston plate is driven to move in the air cylinder 18 toward the side away from the conveyor belt 1, so that the air in the air cylinder 18 is ejected from the air jet pipe 19 and finally blown onto the grinding ring 21, so that the bamboo chips on the grinding ring 21 can be cleaned. When the piston plate moves toward the side close to the conveyor belt 1, the outside air can be sucked into the air cylinder 18 through the air inlet pipe.

[0047] The implementation principle of this embodiment is as follows: during operation, the bamboo sticks placed in the hopper 2 will fall on the top surface of the conveyor belt 1 in sequence, and then fall into the placement groove during the rotation of the conveyor belt 1. After that, the bamboo sticks can follow the rotation of the conveyor belt 1 and approach the grinding mechanism. The conveyor belt 1 rotates intermittently. When the placement groove moves with the bamboo sticks to a position that coincides with the axis of the guide cylinder 15, the conveyor belt 1 stops for a period of time. During this period, the telescopic member 4 first extends, thereby driving the push plate 5 to approach the conveyor belt 1, and the push rod 6 also enters the placement groove. When the push rod 6 contacts the bamboo sticks in the placement groove, it pushes the bamboo sticks toward the guide cylinder 15, and the bamboo sticks enter from the side with the larger opening of the guide cylinder 15, and then pass through the side with the smaller opening of the guide cylinder 16. , and finally pass through the grinding ring 21, which can grind the burrs on the outer surface of the bamboo stick. Finally, the polished bamboo stick will enter between the two guide rollers 16, and the two guide rollers 16 rotate towards each other to apply an outward pulling force to the bamboo stick. When the push rod 6 is out of contact with the bamboo stick, the guide roller 16 can continue to pull the bamboo stick out of the guide cylinder 15 completely, so that the entire bamboo stick is completely polished. After the bamboo stick is separated from the conveyor belt 1, the conveyor belt 1 rotates again, so that the bamboo sticks in the adjacent placement grooves are moved to a position coaxial with the guide cylinder 15, the conveyor belt 1 stops again, and then the pushing mechanism runs again, and the cycle is repeated, thereby completing the deburring process for the bamboo sticks in each placement groove.

[0048] Embodiment 2:

[0049] Combination Figure 1 - Figure 3 Based on Example 1, this embodiment is further improved in that: the linkage mechanism includes a linkage gear 8 rotatably connected to the top surface of the mounting platform 3, an active rack 7 fixed on the push plate 5, and a driven rack 9 fixed on the piston plate. The active rack 7 and the driven rack 9 are both arranged along the axial direction of the air cylinder 18. The active rack 7 and the driven rack 9 are respectively located on both sides of the linkage gear 8 and are meshed with the linkage gear 8. The movement of the push plate drives the driven rack 9 to move in the opposite direction to it, and then the piston plate can be driven to move inside the air cylinder 18, thereby automatically completing the suction and exhaust actions.

[0050] The implementation principle of this embodiment is: during grinding, in the process that the push plate 5 drives the active rack 7 to approach the conveyor belt 1, the active rack 7 drives the linkage gear 8 to rotate forward, and the linkage gear 8 then drives the driven rack 9 to move in the opposite direction of the active rack 7, so that the piston plate approaches the conveyor belt 1, and the outside air enters the inside of the air cylinder 18 through the air intake pipe. After the grinding is completed, the push plate 5 is away from the conveyor belt 1, thereby driving the active rack 7 to move to the side away from the conveyor belt 1. At this time, the active rack 7 drives the driven rack 9 to move to the side away from the push plate 5 through the linkage gear 8, thereby pushing the piston plate to the side away from the conveyor belt 1, and the air in the air cylinder 18 is pressed into the air injection pipe 19 and discharged, thereby blowing off the bamboo chips on the grinding ring 21.

[0051] Embodiment 3:

[0052] Combination Figure 3 - Figure 5 Based on Example 1, this embodiment is further improved in that: the connecting piece includes a fixing rod 13 fixed to the bottom surface of the top plate 12 and a connecting sleeve 22 fixed to the top surface of the guide cylinder 15, a plug rod matched with the inner circle of the connecting sleeve 22 is fixed to the bottom of the fixing rod 13, a fixing bolt is screwed on the outer periphery of the connecting sleeve 22, and one end of the fixing bolt abuts against the outer periphery of the plug rod, and the connecting sleeve is fixed to the fixing rod 13 by using the friction between the fixing bolt and the plug rod.

[0053] The implementation principle of this embodiment is: after the fixing bolts are loosened, the connecting sleeve 22 can be removed from the fixing rod 13, so that the grinding ring can be easily repaired or replaced. During installation, it is only necessary to insert the insertion rod into the connecting sleeve 22 and then tighten the fixing bolts.

[0054] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention.
