[0015] The U-shaped frame can be easily moved by the user, and the lifting device can be easily moved by the user to move the lift frame upwards, thereby preventing the user from moving the lift frame upwards.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects: In the above scheme, the motor drives the feeding screw rod to rotate inside the main body and the assembled curved feeding pipe through a belt sleeved between the output end and the outer wall of the feeding screw rod. During the rotation of the motor output end, the extended reciprocating screw rod is driven to rotate synchronously, and the connection between the reciprocating screw rod sleeve frame and the extended reciprocating screw rod is driven to reciprocate on the two limit sliding bars respectively. The connection between the upper extension rod and the detachable connecting strip can push the movable crank to move inside the bar-shaped movable hole, and the movable crank is connected with the slide groove block and the top of the feed push piece at one end away from the rotating rod by rotation, so as to push the rotating rod to rotate on the rotating hole frame, thereby driving the feeding screw rod to rotate inside the storage barrel, and transporting the filling inside the storage barrel to the inside of the main body, and then transporting the filling to the inside of the assembled curved feeding pipe through the rotation of the feeding screw rod inside the main body, and then through the assembly The curved feed pipe conveys the filling to the core of the central wrapper. Through the above method, the rotation speeds of the feeding screw and the feeding screw can be coordinated, so that the amount of filling inside the storage barrel entering the main body corresponds to the speed at which the feeding screw rotates to transmit the filling. This not only avoids the mismatch between the rotation speed of the feeding screw inside the storage barrel and the rotation speed of the feeding screw, which causes too much or too little filling to enter the main body and affects the accuracy of the device in quantitative feeding and conveying of the filling, but also the feeding screw and the feeding screw are driven to rotate by the same driving source motor, instead of two driving devices driving the feeding screw and the feeding screw respectively. There is no need to debug the two sets of driving devices additionally, and the amount of filling conveyed by the device can be controlled by controlling the motor speed, which facilitates the operation of the device and reduces the failure rate of the device.

[0017] When the movable crank pushes the material feeding push piece to rotate continuously with the rotating rod as the axis, a thrust will be applied to the contact rotating column to move toward the center of the extension cylinder, so that the contact rotating column moves toward the center of the extension cylinder inside the slide block, and at the same time, the limit push block is pushed toward the center of the extension cylinder, and at the same time, the pressure spring between the limit push block and the side of the slide block close to the center of the extension cylinder is squeezed. When the contact rotating column slides to the slope surface of the sloped curved surface block, the thrust applied to the limit push block and the contact rotating column by the pressure spring cooperates with the slope surface of the sloped curved surface block. When the movable crank, the material feeding push piece and the slide block coincide, and the movable crank is just at the center axis of the extension cylinder, the contact rotating column will have the function of moving along the slope. The force of the slope of the curved surface block sliding toward the lowest point of the sloped curved surface block is formed through the two sloped curved surface blocks in a circular array at the top of the extension cylinder with the extension cylinder as the center, so that when the reciprocating screw sleeve reciprocates on the extended reciprocating screw, the rotating rod is synchronously driven to rotate continuously in a circular motion on the rotating hole frame. When the motor runs too slowly and the connection between the active crank and the feed push piece is just on the central axis of the extension cylinder, the active crank is prevented from pulling the feed push piece to rotate in the opposite direction with the rotating rod as the axis, thereby improving the smoothness of the rotation of the rotating rod inside the rotating hole frame. During the rotation of the feeding screw rod, the two inner wall scraping strips will be driven to rotate synchronously with the feed push piece, so that the two inner wall scraping strips can rotate on the inner wall of the storage barrel, and the filling stuck to the inside of the storage barrel can be continuously scraped off, avoiding the filling sticking to the inner wall of the storage barrel for a long time and affecting the feeding screw rod to input the filling into the main body, and the feeding push piece is used to prevent the filling from being blocked in the extension barrel due to the obstruction of the rotating hole frame after the filling is added to the inside of the extension barrel.

[0018] When the two sliding frames are driven to slide on the two limit slides to the side away from the main body by extending the reciprocating screw rod and cooperating with the reciprocating screw rod sleeve, the two sliding sleeve frames are respectively driven to slide on the two limit slides to the side away from the main body through the two ends of the lifting connecting rod being respectively connected with the bottom of the sliding sleeve frame and the rotation of the lifting connecting frame, so that the angle between the lifting connecting rod and the limit slide becomes smaller, and the end of the lifting connecting rod away from the sliding sleeve frame gradually approaches the main body, which can pull the lifting connecting frame to slide on the bar hole column, thereby driving the U-shaped frame to pass through the two bar hole columns to slide upward, thereby driving a knocking wheel group close to the first side connecting strip to resist the arc surface of the upward pushing block during the rising process, and when a knocking wheel group close to the first side connecting strip continues to rise, it will push the side sliding rod to pass through the side of the U-shaped frame close to the first side connecting strip to slide. The contraction spring is stretched, and when the knocking wheel group passes one of the upward pushing blocks, the elastic force of the contraction spring and the knocking wheel group hit the surface of the storage barrel at the same time, causing the storage barrel to vibrate as a whole. The generated vibration will be transmitted to the fillings piled together, so that the fillings stuck together are gradually dispersed to the surroundings inside the storage barrel due to the vibration, so that the fillings are covered on the top of the feeding screw rod, and the feeding screw rod fully transfers the fillings to the inside of the main body each time, avoiding the fillings sticking together, resulting in the feeding screw rod failing to fill the spiral spacing of the feeding screw rod when transferring the fillings inside the storage barrel to the inside of the main body, thereby failing to fully transfer the fillings to the inside of the main body, thereby improving the accuracy of the equipment in quantitative feeding and conveying of fillings.

[0019] When the knocking wheel group rises to the highest point, the output end of the spring telescopic rod will just correspond to the socket on the first side connecting strip. Through the elasticity of the output end of the spring telescopic rod itself, the output end of the spring telescopic rod will be directly popped out, so that the output end of the spring telescopic rod is inserted into the socket on the first side connecting strip. At the same time, the top of the pressing movable wheel group will abut against the top of the upper abutment frame, and the pressing movable wheel group will rotate on the second side connecting strip, so that the lifting wheel group is away from one end of the pressing movable wheel group and the L-shaped lifting frame is lifted upward, and the output end of the spring telescopic rod close to the second side connecting strip is pushed out of the socket on the second side connecting strip through the top block 2. After the contraction spring in the stretched state loses the force of limiting the connection between the output end of the spring telescopic rod and the socket on the second side connecting strip, the spring telescopic rod will be pulled to reset, and a knocking wheel group close to the second side connecting strip will knock on the surface of the storage barrel. When a knocking wheel group close to the second side connecting strip drops to the bottom, The cam is pressed against the bottom of the frame and the push rod is pressed against the bottom of the frame to push the cam out of the way so that the cam is in a position to move relative to the push rod and push the cam back into position.

The movable crank 305 is driven to move inside the bar-shaped movable hole 205 through the detachable connecting strip 304 and the two upper extension rods 303. When the rotating rod 208 is pushed to rotate, the highest point of the contact rotating column 402 and the sloped curved surface block 206 will be against each other. Since the contact parts of the contact rotating column 402 and the sloped curved surface block 206 are all curved surfaces, when the movable crank 305 pushes the feed push piece 211 to continue to rotate around the rotating rod 208 as the axis When the contact rotating column 402 is pushed toward the center of the extension cylinder 204, the contact rotating column 402 is pushed toward the center of the extension cylinder 204 inside the slide block 401, and the limit push block 404 is pushed toward the center of the extension cylinder 204. At the same time, the pressure spring 405 between the limit push block 404 and the side of the slide block 401 close to the center of the extension cylinder 204 is squeezed. When the contact rotating column 402 slides onto the slope of the sloped curved surface block 206, the thrust applied by the pressure spring 405 to the limit push block 404 and the contact rotating column 402 is The slope of the surface block 206 cooperates. When the movable crank 305, the feed push piece 211 and the slide block 401 overlap, and the movable crank 305 is exactly on the central axis of the extension tube 204, the contact rotating column 402 will have a force to slide along the slope of the sloped curved surface block 206 to the lowest point of the sloped curved surface block 206. Through the two sloped curved surface blocks 206, the top of the extension tube 204 is arranged in a circular array with the extension tube 204 as the center. When the reciprocating screw rod sleeve 302 reciprocates on the extended reciprocating screw rod 109, the rotating rod 208 is synchronously driven to continuously rotate in a circular manner on the rotating hole frame 207. like Figure 1 , Figure 2 , Figure 6 , Figure 7 and Fig. 9As shown, a knocking mechanism 5 is provided at the bottom of the two sliding sleeve frames 301, and the knocking mechanism 5 includes two lifting connecting rods 501, and the two lifting connecting rods 501 are respectively rotatably connected to the bottom of the two sliding sleeve frames 301, and the ends of the two lifting connecting rods 501 away from the sliding sleeve frames 301 are rotatably connected to the lifting connecting frames 502, and the outer walls of the two lifting connecting frames 502 are respectively slidably connected to the inside of the two bar hole columns 102, and the tops of the two lifting connecting frames 502 are fixedly connected with U-shaped frames 503, and the U-shaped frames 503 slide through the two bar hole columns 102, and the opposite sides of the U-shaped frames 503 are slidably connected with side sliding rods 509, and the side sliding rods 509 close to the storage barrel 201 are fixedly connected with a knocking wheel group 510, and the side sliding rods A spring telescopic rod 511 is fixedly connected to the side of 509 away from the knocking wheel group 510, and a contraction spring 512 is fixedly connected between the spring telescopic rod 511 and the U-shaped frame 503. A first side connecting strip 504 is fixedly connected to the outer wall of the U-shaped frame 503, and a second side connecting strip 505 is fixedly connected to the side of the U-shaped frame 503 away from the first side connecting strip 504. The second side connecting strip 505 and the end of the first side connecting strip 504 away from the U-shaped frame 503 are penetrated by a socket, and a connecting slide rod 506 is slidably connected to the end of the top of the first side connecting strip 504 away from the U-shaped frame 503, and a contact plate 507 is fixedly connected to the bottom of the connecting slide rod 506. The top of the contact plate 507 is away from the connecting slide rod 506. One end is fixedly connected with a top block 508, and the output end of the spring telescopic rod 511 is plugged into the socket on the first side connecting strip 504, and the top block 508 is plugged into the socket on the first side connecting strip 504, and the bottom of the contact plate 507 is against the lower bracket 103. The two ends of the lifting connecting rod 501 are respectively connected with the bottom of the sliding sleeve frame 301 and the lifting connecting frame 502, so that the angle between the lifting connecting rod 501 and the limiting sliding strip 106 becomes smaller, and the end of the lifting connecting rod 501 away from the sliding sleeve frame 301 gradually approaches the main body 1, and the lifting connecting frame 502 can be pulled to slide on the bar hole column 102, thereby driving the U-shaped frame 503 to pass through the two bar hole columns 102 and slide upward, thereby driving the lifting connecting frame 502 near the first side connecting strip. When the knocking wheel group 510 of 504 is rising, it abuts against the arc surface of the upward pushing block 202. When the knocking wheel group 510 near the first side connecting strip 504 continues to rise, it pushes the side sliding rod 509 to pass through the side of the U-shaped frame 503 near the first side connecting strip 504 to slide, and at the same time, the contraction spring 512 is stretched. When the knocking wheel group 510 passes through one of the upward pushing blocks 202, the elastic force of the contraction spring 512 simultaneously knocks the wheel group 510 on the surface of the storage barrel 201, so that the storage barrel 201 vibrates as a whole. The generated vibration is transmitted to the fillings piled together, so that the fillings stuck together are gradually dispersed to the surroundings inside the storage barrel 201 due to the vibration. like Figure 1 , Figure 2 and Fig. 9As shown, a matching mechanism 6 is provided at one end of the outer wall of the second side connecting strip 505 away from the U-shaped frame 503, and the matching mechanism 6 includes a second connecting slide bar 601, and the second connecting slide bar 601 is slidably connected to the end of the bottom of the second side connecting strip 505 away from the U-shaped frame 503, and an L-shaped lifting frame 602 is fixedly connected to the bottom of the second connecting slide bar 601, and a top block 603 is fixedly connected to the top of the L-shaped lifting frame 602 at a place corresponding to the socket on the second side connecting strip 505, and the top block 603 is connected to the second side connecting strip 50 5, the end of the outer wall of the second side connecting strip 505 away from the U-shaped frame 503 is rotatably connected to the pressing movable wheel set 604, the end of the pressing movable wheel set 604 away from the second side connecting strip 505 is against the inner wall of the top of the upper support frame 104, the outer wall of the pressing movable wheel set 604 is fixedly connected to the movable crank 305, the end of the movable crank 305 away from the pressing movable wheel set 604 is against the inside of the L-shaped lifting frame 602, and when the knocking wheel set 510 rises to the highest point, the output of the spring telescopic rod 511 The output end will just correspond to the socket on the first side connecting strip 504. Through the elasticity of the output end of the spring telescopic rod 511, the output end of the spring telescopic rod 511 will be directly ejected, so that the output end of the spring telescopic rod 511 is inserted into the socket on the first side connecting strip 504. At the same time, the top of the downward pressing movable wheel group 604 will abut against the top of the upper support frame 104, and the downward pressing movable wheel group 604 will rotate on the second side connecting strip 505, so that the lifting wheel group 605 away from the end of the downward pressing movable wheel group 604 is tilted and The L-shaped lifting frame 602 is lifted upward, and the output end of a spring telescopic rod 511 close to the second side connecting strip 505 is pushed out of the socket on the second side connecting strip 505 through the top block 2 603. After the contraction spring 512 in the stretched state loses the limiting force generated by the output end of the spring telescopic rod 511 plugging into the socket on the second side connecting strip 505, the spring telescopic rod 511 is pulled to reset, and a knocking wheel group 510 close to the second side connecting strip 505 knocks on the surface of the storage barrel 201.

[0032] The working principle of the technical solution provided by the present invention is as follows: The movable crank 305 is driven to move inside the bar-shaped movable hole 205 by assembling and connecting the detachable connecting strip 304 and the two upper extension rods 303. When the rotating rod 208 is pushed to rotate, the contact rotating column 402 will be against the highest point of the sloped curved surface block 206. Since the contact parts of the contact rotating column 402 and the sloped curved surface block 206 are all curved surfaces, when the movable crank 305 pushes the feed push piece 211 to continue to rotate with the rotating rod 208 as the axis, a thrust is applied to the contact rotating column 402 to move toward the center of the extension tube 204, so that the contact rotating column 402 moves inside the slide block 401 toward the center of the extension tube 204. The movable crank 305 and the feed push piece 211 are coincident with each other, and the movable crank 305 is exactly on the central axis of the extension tube 204. The force of sliding along the slope of the sloped curved surface block 206 toward the lowest point of the sloped curved surface block 206 is generated, and the two sloped curved surface blocks 206 are arranged in a circular array at the top of the extension tube 204 with the extension tube 204 as the center, so that when the reciprocating screw sleeve 302 reciprocates on the extended reciprocating screw 109, the rotating rod 208 is synchronously driven to rotate continuously in a circular manner on the rotating hole frame 207, and when the motor 107 runs too slowly and the connection between the movable crank 305 and the feed push piece 211 is just at the central axis of the extension tube 204, the movable crank 305 is prevented from pulling the feed push piece 211 to rotate in the opposite direction with the rotating rod 208 as the axis, thereby improving the performance of the present invention. The high rotating rod 208 rotates smoothly inside the rotating hole frame 207. During the rotation of the feeding screw rod 209, the two inner wall scraping strips 210 and the feeding push piece 211 will be driven to rotate synchronously, so that the two inner wall scraping strips 210 can rotate on the inner wall of the storage barrel 201 to continuously scrape off the fillings stuck to the inside of the storage barrel 201, so as to prevent the fillings from sticking to the inner wall of the storage barrel 201 for a long time and affecting the feeding screw rod 209 to input the fillings into the main body 1. The feeding push piece 211 can prevent the fillings from being blocked in the extension barrel 204 due to the obstruction of the rotating hole frame 207 after the fillings are added into the extension barrel 204. When the two sliding frames 301 are driven to slide on the two limiting slide bars 106 to the side away from the main body 1 by extending the reciprocating screw rod 109 and cooperating with the reciprocating screw rod sleeve frame 302, the two ends of the lifting connecting rod 501 are respectively connected to the bottom of the sliding frame 301 and the lifting connecting frame 502, so that the angle between the lifting connecting rod 501 and the limiting slide bar 106 becomes smaller, and the end of the lifting connecting rod 501 away from the sliding frame 301 gradually approaches the main body 1, which can pull the lifting connecting frame 502 to slide on the bar hole column 102, thereby driving the U-shaped frame 503 to pass through the two bar hole columns 102 and slide upward, thereby driving a knocking wheel group 510 close to the first side connecting bar 504 to resist the arc surface of the upward pushing block 202 during the rising process, and When a knocking wheel group 510 near the first side connecting strip 504 continues to rise, it will push the side sliding rod 509 to slide through the side of the U-shaped frame 503 near the first side connecting strip 504, and at the same time stretch the contraction spring 512. When the knocking wheel group 510 passes through one of the upward pushing blocks 202, the elastic force of the contraction spring 512 and the knocking wheel group 510 hits the surface of the storage barrel 201 at the same time, so that the storage barrel 201 vibrates as a whole, and the generated vibration is transmitted to the fillings piled together, so that the fillings stuck together are gradually dispersed to the surroundings inside the storage barrel 201 due to the vibration, so that the fillings are covered on the top of the feeding screw rod 209, and the feeding screw rod 209 fully transmits the fillings to the inside of the main body 1 every time; When the knocking wheel group 510 rises to the highest point, the output end of the spring telescopic rod 511 will just correspond to the socket on the first side connecting strip 504. Through the elasticity of the output end of the spring telescopic rod 511, the output end of the spring telescopic rod 511 will be directly ejected, so that the output end of the spring telescopic rod 511 is inserted into the socket on the first side connecting strip 504. At the same time, the top of the pressing movable wheel group 604 will be against the top of the upper support frame 104, and the pressing movable wheel group 604 will rotate on the second side connecting strip 505, so that the lifting wheel group 605 is away from the pressing movable wheel group 604. The first end of the L-shaped lifting frame 602 is tilted and the L-shaped lifting frame 602 is lifted upward, and the output end of a spring telescopic rod 511 close to the second side connecting strip 505 is pushed out of the socket on the second side connecting strip 505 through the top block 203. After the contraction spring 512 in the stretched state loses the force of the output end of the spring telescopic rod 511 plugging into the socket on the second side connecting strip 505 to generate a limiting force, the spring telescopic rod 511 will be pulled back to its original position, and a knocking wheel group 510 close to the second side connecting strip 505 will knock on the surface of the storage barrel 201. After the striking wheel assembly 510 descends to the bottom, a downward-moving pushing block 203 at the bottom is longer than the other downward-moving pushing blocks 203, so that a spring telescopic rod 511 close to the second side connecting strip 505 can be directly pushed to move to the top of the socket on the second side connecting strip 505, so that the output end of the spring telescopic rod 511 close to the second side connecting strip 505 corresponds to the socket on the second side connecting strip 505, and the output end of the spring telescopic rod 511 is inserted into the second side connecting strip 505 through the elastic force of the spring inside the spring telescopic rod 511 close to the second side connecting strip 505. The contact plate 507 is inside the socket on the strip 505, and after the U-shaped frame 503 drops to the bottom, it will abut and squeeze the lower bracket 103, and push the output end of a spring telescopic rod 511 close to the first side connecting strip 504 out of the socket on the first side connecting strip 504 through the top block 508, so that the knocking wheel group 510 knocks on the outer wall of the storage barrel 201 through the restoring force of the contraction spring 512, and reciprocates in sequence. The storage barrel 201 can be knocked during the lifting and lowering process of the U-shaped frame 503, so that the filling is more dispersed inside the storage barrel 201.
