Description

Technical Field

[0001] The invention relates to the technical field of cutting and grinding equipment, and in particular to a cutting equipment for bead core processing. Background Art

[0002] The pearl nucleus is also called the pearl nucleus. The shell is cut and ground into powder to make a perfect circle of 2-20mm. The pearl nucleus is placed in the mother-of-pearl to become an artificially cultivated pearl. Some artificially cultivated pearls and natural pearls have pearl nuclei inside. In the prior art, the shell is usually cut and crushed in advance using a cutting device, and then ground into a pearl nucleus; Therefore, a shell powder grinding device with patent number CN201810904307.2 is proposed in the prior art. Through the feed funnel and the leakage screen installed on the upper side of the grinding box, the flow rate and speed of the shell powder entering the grinding box can be effectively controlled to avoid the equipment from running poorly due to too much shell powder in the grinding box, thereby improving the grinding efficiency. The shell powder processing box and the grinding box are connected by a threaded coupler, which can facilitate the replacement of equipment and adapt to different process needs, thereby improving the functionality of the equipment. Through the discharge pipe and the super-dense discharge hole installed on the right side of the shell powder processing box, the discharge speed can be stabilized, which is convenient for personnel to collect and saves manpower. However, when this device is actually used to grind shell powder, due to the different sizes of shells, the larger shell powder directly enters the grinding box, and the shells can only be cut and ground once, resulting in different sizes of shell powder after grinding and poor cutting and grinding effect.

DETAILED DESCRIPTION

[0018] Example 1, please refer to Figure 1-7 A cutting device for bead core processing includes a workbench 1 and a support frame 101. The left and right ends of the upper surface of the workbench 1 are fixed with support frames 101, and the left and right ends of the bottom of the two support frames 101 are fixed with servo motors 102. A cutting barrel 2 is rotatably connected above the two support frames 101, a feeding hopper 201 is fixed at the front end of the cutting barrel 2, a guide plate 202 is fixed at the lower part of the cutting barrel 2, a discharge pipe 203 is vertically embedded at the left side of the bottom end of the cutting barrel 2, an upper servo motor 204 and a lower servo motor 205 are respectively fixed at the upper and lower ends of the cutting barrel 2, and a cutting assembly is arranged inside the cutting barrel 2.

[0019] Connecting rods are transversely fixed in the middle of the left and right ends of the cutting barrel 2. The power output ends of the two servo motors 102 are rotatably connected to the connecting rods at the left and right ends of the cutting barrel 2 through transmission shafts, respectively. The cutting barrel 2 rotates 180° forward and backward between the two support frames 101. After the raw materials enter the interior of the cutting barrel 2 along the feeding hopper 201, they will fall due to the action of gravity, contact the auxiliary blade 210 and the upper cutting blade 211 rotating on the outer wall of the upper cutting column 206, and then contact the auxiliary blade 210 and the lower cutting blade 212 rotating on the outer wall of the lower cutting column 207 to be crushed, and then enter the limiting ring 209 below the cutting barrel 2 to be ground by the grinding disc 208, and then the servo motor 102 drives the cutting barrel 2 to rotate 180° between the two support frames 101 so that the lower servo motor 205 is located at the top. At this time, the raw materials fall due to gravity again, and contact the lower cutting blade 212 and the auxiliary blade 210 rotating on the outer wall of the lower cutting column 207 in turn, and then contact the upper cutting blade 211 and the auxiliary blade 210 rotating on the outer wall of the upper cutting column 206, and then enter the limiting ring 209 to be ground by the grinding disc 208, thereby repeatedly cutting and grinding the raw materials for bead core production, and the cutting and grinding effect is good.

[0020] Example 2, please refer to Figure 1-7 , Embodiment 2 is different from Embodiment 1 in that the cutting assembly is composed of an upper cutting column 206, a lower cutting column 207, a grinding disc 208, a limiting ring 209, an auxiliary blade 210, an upper cutting blade 211, a lower cutting blade 212, an upper limiting plate 213 and a lower limiting plate 214; An upper cutting column 206 and a lower cutting column 207 are respectively vertically embedded in the upper and lower ends of the cutting barrel 2, and a grinding disc 208 is fixed in the middle of the upper and lower cutting columns 206 and 207. Limiting rings 209 are fixed to the upper and lower ends of the cutting barrel 2, and auxiliary blades 210 and upper cutting blades 211, auxiliary blades 210 and lower cutting blades 212 are respectively fixed to the outer walls of the upper and lower cutting columns 206 and 207. An upper limit plate 213 and a lower limit plate 214 are respectively fixed to the upper and lower ends of the cutting barrel 2. The power output end of the upper servo motor 204 is connected to the upper cutting column 206 in a clockwise rotational direction, and the power output end of the lower servo motor 205 is connected to the lower cutting column 207 in a counterclockwise rotational direction; The auxiliary blade 210 and the upper cutting blade 211 on the upper cutting column 206 are both arranged in an arc shape opening in the clockwise direction, and the auxiliary blade 210 and the lower cutting blade 212 on the lower cutting column 207 are both arranged in an arc shape opening in the counterclockwise direction; The bottom end of the auxiliary blade 210 on the upper cutting column 206 is in close contact with the top end of the upper limit plate 213, and the top end of the auxiliary blade 210 on the lower cutting column 207 is in close contact with the bottom end of the lower limit plate 214. The rotation area of ​​the auxiliary blade 210 around the upper cutting column 206 and the lower cutting column 207 is consistent with the cross-sectional area of ​​the upper limit plate 213 and the lower limit plate 214. The auxiliary blade 210 is mainly used to pre-cut the raw materials entering the upper limit plate 213 and the lower limit plate 214 to prevent larger raw materials from being stuck in the through holes of the upper limit plate 213 and the lower limit plate 214. The upper cutting blade 211 and the lower cutting blade 212 are arranged between the upper limit plate 213 and the lower limit plate 214. The upper and lower ends of the upper cutting blade 211 and the lower cutting blade 212 are respectively provided with two cutting edges. The bottom of the upper cutting blade 211 and the top of the lower cutting blade 212 are both on the same horizontal plane. When the raw material passes between the upper cutting blade 211 and the lower cutting blade 212, the upper cutting blade 211 and the lower cutting blade 212 rotating in clockwise and counterclockwise directions rotate in opposite directions at the same time to clamp the raw material before cutting, so that the cutting force on the raw material is greater and the cutting efficiency is higher; The upper limit plate 213 and the lower limit plate 214 are provided with through holes in their internal vertical openings, so that the bottom end of the upper cutting blade 211 is in close contact with the bottom end of the upper limit plate 213 , and the bottom end of the lower cutting blade 212 is in close contact with the top end of the lower limit plate 214 ; When the raw material passes through the through holes of the upper limit plate 213 and the lower limit plate 214, since the top of the upper cutting blade 211 is close to the bottom of the upper limit plate 213 and the bottom of the lower cutting blade 212 is close to the top of the lower limit plate, if the rotating upper cutting blade 211 pushes the raw material to move when it contacts the raw material, the raw material will contact one end of the through holes of the upper limit plate 213 and the lower limit plate 214 and then be cut, and the raw material will not rotate with the rotation of the upper cutting blade 211 or the lower cutting blade 212, so the cutting force on the raw material is relatively large; The grinding discs 208 on the upper cutting column 206 and the lower cutting column 207 are just embedded in the limiting rings 209 at the upper and lower ends of the cutting barrel 2, and the upper limiting plate 213 and the lower limiting plate 214 are just located between the two limiting rings 209. The outer wall opening of the grinding disc 208 is provided with six guide grooves, and the inner wall of the limiting ring 209 is provided with a raised grinding surface; When the cut raw material falls, it will enter the inside of the limit ring 209 along the grinding disc 208, and will be ground into fine powder by the rotating grinding disc 208; The main function of the guide groove is to facilitate the cut raw material to quickly enter the limiting ring 209 and be pushed by the rotating grinding disc 208 to contact the inner wall of the limiting ring 209 .

[0021] Example 3, please refer to Figure 1-7 , Embodiment 3 is different from Embodiment 2 in that the guide plate 202 is arranged at the bottom of the cutting barrel 2 in an inclined shape with the left side lower and the right side higher, the discharge pipe 203 is arranged at the leftmost lower part of the guide plate 202, and the discharge end of the hopper 201 is arranged above the front end of the upper limit plate 213; When the raw materials are poured into the hopper 201 , the raw materials fall along the hopper 201 onto the upper limit plate 213 ; When the raw material falls on the upper surface of the guide plate 202 after being cut and ground, it will slide from right to left along the upper surface of the guide plate 202 and then be discharged along the discharge pipe 203, so that the cut and ground raw material can be collected.

[0022] The above are only preferred embodiments of the present invention. It should be pointed out that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present invention. These should also be regarded as the protection scope of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent.
