[0002] Pet food is specially provided for pets and small animals, and its main function is to provide the most basic life guarantee, growth and development, and the nutrients required for health for various pets.

[0003] Pets such as cats and dogs are more popular. For pet food for cats and dogs, the raw materials include meat, and fish, beef, pork, etc. are relatively common. For meat raw materials, during the production process, a grinding meat grinder is used to grind and crush the meat. The grinding meat shaft knife in the meat grinding cylinder is driven by a reduction motor to rotate, and the meat raw materials entering the meat grinding cylinder are ground and crushed. The ground and crushed meat material is extruded from the hole plate provided at the outlet end of the grinding meat grinder, and the extruded meat material is in the shape of meat paste. Generally, after long-term extrusion of meat material, meat material residues will remain in the holes of the hole plate. When cleaning the equipment, the hole plate needs to be cleaned.

The motor end of the electric push rod 802 is connected to the arc-shaped plate 801. A wiring terminal is provided at the motor of the electric push rod 802, and it can be connected to electricity through a wire. The screw end of the electric push rod 802 is connected to the sleeve 500. The motor of the electric push rod 802 can push the screw to move back and forth. By retracting the screw through the motor, the sleeve 500 is driven to move towards the inlet end direction of the meat grinding cylinder 300 until the sleeve 500 covers the discharge end of the meat grinding cylinder 300; or the screw can be pushed out through the motor, so as to push the sleeve 500 out from the discharge end of the meat grinding cylinder 300, so that there is enough space between the sleeve 500 and the discharge end of the meat grinding cylinder 300, and the dredging mechanism 1000 can be pushed into the sleeve 500 from the corresponding space to clean the residual material.

The longitudinal section of the U - shaped block A718 is connected to the outer end of the movable rod 709. On the other side of the connecting plate 713, two clamping blocks 720 are symmetrically and movably provided. The two clamping blocks 720 are clamped and matched with the connecting rod 1003. At the ends of the two clamping blocks 720, movable blocks 716 are respectively fixedly provided. The movable blocks 716 are inserted into a through - groove 7131 opened on the connecting plate 713. At both ends on one side of the connecting plate 713, end blocks 714 are respectively fixedly provided. One end block 714 is rotatably connected to one end of the left - hand and right - hand screw 715 through a rotating shaft. The other end of the left - hand and right - hand screw 715 is inserted into a hole of the other end block 714. The two threaded sections of the left - hand and right - hand screw 715 are respectively threadedly inserted into threaded holes on the two movable blocks 716. A rotating handle 717 is fixedly provided at the other end of the left - hand and right - hand screw 715. Anti - slip threads are provided on the outer wall of the rotating handle 717. Among them, circular grooves 7201 are respectively opened at the upper and lower ends on the opposite sides of the two clamping blocks 720. The circular grooves 7201 are clamped and matched with the connecting rod 1003. Square grooves 7202 are respectively opened in the middle sections on the opposite sides of the two clamping blocks 720. The square grooves 7202 are clamped and matched with a sleeve block 1004 sleeved on the connecting rod 1003. When the two clamping blocks 720 clamp and position the connecting rod 1003, through the docking of the sleeve block 1004 and the square groove 7202, the connecting rod 1003 is kept stable when being clamped, and the connecting rod 1003 is not easily separated.

[0074] When the connecting rod 1003 enters the insertion groove 504 in a longitudinal state correspondingly, the disc 1001 enters the inner ring groove 501 correspondingly. The connecting rod 1003 is located between the two clamping blocks 720. Rotate the rotating handle 717 to drive the left - hand and right - hand screw 715 to rotate. One end of the left - hand and right - hand screw 715 rotates relative to one end block 714. The two movable blocks 716 threadedly connected to the two threaded sections of the left - hand and right - hand screw 715 move relatively along the through - groove 7131 until the two clamping blocks 720 clamp and position the connecting rod 1003. The connecting rod 1003 is clamped in the circular groove 7201. At this time, the sleeve block 1004 is correspondingly clamped and positioned in the square groove 7202, so as to keep the connecting rod 1003 positioned stably. Rotating the rotating handle 717 in the reverse direction can drive the two movable blocks 716 to move away from each other along the through - groove 7131, and the two clamping blocks 720 move away from each other to release the connecting rod 1003.

[0075] By providing the connecting plate 713, the end blocks 714, the left - hand and right - hand screw 715, the movable blocks 716, the rotating handle 717, the U - shaped block A718, the sealing block 719 and the clamping blocks 720, the present invention has the advantage of being convenient for adjusting and clamping and positioning the connecting rod 1003.

[0076] Among them, a block groove 7203 is provided in the inner rear wall of the square groove 7202 of one clamping block 720, and a limit block 7204 is fixedly provided on the outer side of the rear wall of the square groove 7202 of the other clamping block 720. The limit block 7204 is inserted and matched with the block groove 7203, and the limit block 7204 is limited and matched with the sleeve block 1004. When the two clamping blocks 720 are separated, the limit block 7204 is separated from the block groove 7203, and when the connecting rod 1003 is pushed in, the sleeve block 1004 contacts the limit block 7204 and limits the sleeve block 1004, indicating that the sleeve block 1004 is in the correct position at this time, and the two clamping blocks 720 can be adjusted to move relative to clamp the connecting rod 1003, and the sleeve block 1004 will enter the square groove 7202 accordingly.

[0077] Among them, a slider 721 is fixed at the end of the clamping block 720, and a slide groove 7132 is opened on the other side of the connecting plate 713. The slider 721 slides with the slide groove 7132, and the slider 721 is adapted to the slide groove 7132. The two ends of the connecting plate 713 are respectively fixed with sealing blocks 719, and the sealing blocks 719 block the two ends of the slide groove 7132. The slider 721 moves along the slide groove 7132 and will not be separated from the slide groove 7132. The slider 721 plays the role of limiting the clamping block 720 in the slide groove 7132.

[0078] The present invention has the advantage of providing a reciprocating mechanism 700, which can be operated from the outside of the sleeve 500 to drive the disc 1001 to reciprocate in the inner annular groove 501, so that the dredging column 1002 passes through the holes on the orifice plate 600 back and forth multiple times, and repeatedly cleans the residues in the holes.

[0079] See also Figure 5 , Figure 6 , Figures 12 to 15, an embodiment provided by the present invention: a raw material grinding device for pet food production. A U-shaped block B1006 is embedded in a groove formed in the circumferential wall of a disc 1001. The U-shaped block B1006 is rotatably connected to the bottom of a connecting rod 1003 through a rotating shaft. Among them, the bottom of the connecting rod 1003 is formed into a spherical surface. The spherical surface at the bottom of the connecting rod 1003 is arranged such that when the connecting rod 1003 rotates, the spherical surface will not be obstructed by the transverse section at the bottom of the U-shaped block B1006. Among them, grooves 10061 are respectively formed on the inner sides of the two longitudinal sections of the U-shaped block B1006, and abutting elastic pieces 1007 are arranged in the grooves 10061. The grooves 10061 provide space for the abutting elastic pieces 1007 to retract after being squeezed, without affecting the rotation of the bottom of the connecting rod 1003. Among them, the abutting elastic pieces 1007 are arc-shaped, the arched sections of the abutting elastic pieces 1007 are arranged outside the grooves 10061, and the two straight sections at both ends of the abutting elastic pieces 1007 are respectively fixedly connected to the inner walls of the grooves 10061. The arched sections of the arc-shaped abutting elastic pieces 1007 are smoothly squeezed along the arc when being squeezed by the connecting rod 1003. The two abutting elastic pieces 1007 are respectively in abutting cooperation with two abutting grooves 10031 symmetrically formed on the outer circumferential wall of the bottom of the connecting rod 1003. When the connecting rod 1003 is in the longitudinal state, the abutting grooves 10031 are in abutting contact with the arched ends of the abutting elastic pieces 1007. Through the abutting cooperation between the abutting elastic pieces 1007 and the abutting grooves 10031, the connecting rod 1003 in the longitudinal state is initially kept stable, which is convenient for entering the insertion groove 504.

[0080] The dredging mechanism 1000 further includes a round block 1005 and an arc-shaped insert 1009. A plurality of arc-shaped bottom strips 1008 are arranged in an annular array on the outer peripheral wall of the round block 1005. Among them, the rear end face of the arc-shaped bottom strip 1008 is fixedly connected to the other side of the disc 1001, and the inner end of the arc-shaped bottom strip 1008 is fixedly connected to the outer peripheral wall of the round block 1005; a plurality of arc-shaped inserts 1009 are inserted and matched with arc-shaped grooves 10081 formed on the front end faces of the plurality of arc-shaped bottom strips 1008. Among them, the arc-shaped insert 1009 is made of rubber material, and the cross-section of the arc-shaped insert 1009 is set to be T-shaped, and the arc-shaped insert 1009 is adapted to the arc-shaped groove 10081; the T-shaped arc-shaped insert 1009 is correspondingly inserted into the arc-shaped groove 10081. The arc-shaped insert 1009 made of rubber material has ductility and has an adjustment space when inserted into the arc-shaped groove 10081. After the T-shaped arc-shaped insert 1009 is inserted into the arc-shaped groove 10081, the extrusion and rebound of the rubber material make the connection stable. An arc-shaped connecting strip 1010 is fixedly arranged on the outer arc side of the arc-shaped insert 1009. The arc-shaped connecting strip 1010 is connected with an arc-shaped scraping strip 1011 through two symmetrically distributed arc-shaped elastic pieces 1012. Among them, the cross-section of the arc-shaped elastic piece 1012 is arc-shaped, and rubber strips in an L shape are respectively connected to both ends of the arc-shaped elastic piece 1012. The rubber strips at both ends of the arc-shaped elastic piece 1012 are respectively inserted and matched with grooves formed on the outer arc side of the arc-shaped connecting strip 1010 and the inner arc side of the arc-shaped scraping strip 1011; among them, the cross-section of the arc-shaped scraping strip 1011 is trapezoidal; among them, the outer end of the arc-shaped scraping strip 1011 corresponds to the outer circular edge of the other side of the disc 1001; among them, the scraping side end face of the arc-shaped scraping strip 1011 extends beyond the outer end face of the round block 1005. When scraping and cleaning the inner side of the hole plate 600, the connecting rod 1003 is rotated downward toward the disc 1001 side of the dredging column 1002, and the abutting elastic piece 1007 is squeezed by the rotated connecting rod 1003. The arched section of the abutting elastic piece 1007 is separated from the abutting groove 10031, and the connecting rod 1003 is rotated and adjusted to a horizontal state. The disc 1001 on one side of the arc-shaped scraping strip 1011 can be pushed into the sleeve 500. The connecting rod 1003 is in a horizontal and outward state until it completely contacts the inner side of the hole plate 600. The scraping side end face of the arc-shaped scraping strip 1011 contacts the inner side of the hole plate 600 earlier than the outer end face of the round block 1005. The continuous thrust makes the arc-shaped elastic piece 1012 be squeezed. The rebounding force generated by the squeezed arc-shaped elastic piece 1012 makes the scraping side end face of the arc-shaped scraping strip 1011 closely adhere to the inner side of the hole plate 600. The connecting rod 1003 is used as a handle to drive the disc 1001 to make a circular motion in the insertion groove 504, and the scraping side of the arc-shaped scraping strip 1011 that closely adheres to the inner side of the hole plate 600 scrapes and cleans the inner side of the hole plate 600.

[0081] The present invention has the advantages of high efficiency in scraping and cleaning the inner side of the hole plate 600 and setting a second form to cooperate with the residue treatment of the hole plate 600 by arranging a connecting rod 1003, a U-shaped block B 1006, an abutting elastic piece 1007, an arc-shaped bottom strip 1008, an arc-shaped inserting strip 1009, an arc-shaped connecting strip 1010, an arc-shaped scraping strip 1011 and an arc-shaped elastic piece 1012.

[0082] Working principle: The meat material enters from the feeding cylinder on the meat grinding cylinder 300. The reduction motor 200 drives the coupling 400 and the reamer shaft to rotate. The reamer blades on the rotating reamer shaft grind and crush the meat material in the meat grinding cylinder 300, and push the meat material in the meat grinding cylinder 300 towards the discharge end during the grinding and crushing process. The ground and crushed meat material is extruded through the holes of the hole plate 600.

[0083] To clean the residual meat material on the hole plate 600, the screw rod is pushed out by the motor, and the electric push rod 802 pushes the sleeve 500 out from the discharge end of the meat grinding cylinder 300, so that there is enough space between the sleeve 500 and the discharge end of the meat grinding cylinder 300. The blocking block 901 is pushed out, and the dredging mechanism 1000 is pushed into the sleeve 500 from the corresponding space. At this time, the connecting rod 1003 is in the longitudinal state, and the abutting groove 10031 abuts against the arched end of the abutting elastic piece 1007 to initially position the connecting rod 1003. The disc 1001 is pushed into the sleeve 500, and the longitudinal connecting rod 1003 enters the insertion groove 504. The connecting rod 1003 is moved to be located between the two clamping blocks 720. The sleeve block 1004 contacts the limiting block 7204 to limit the sleeve block 1004. The turning handle 717 is rotated to drive the left-right threaded screw rod 715 to rotate. One end of the left-right threaded screw rod 715 rotates relative to one end block 714. The two movable blocks 716 threadedly connected to the two threaded sections of the left-right threaded screw rod 715 move relative to each other along the through groove 7131, and the slider 721 moves along the sliding groove 7132 until the two clamping blocks 720 clamp and position the connecting rod 1003. The connecting rod 1003 is clamped in the circular groove 7201. At this time, the sleeve block 1004 is correspondingly clamped and positioned in the square groove 7202, and the positioning of the connecting rod 1003 is kept stable. The staff holds the rubber sleeve by hand, thus holding the longitudinal grip rod, and makes a circular motion to push the grip rod to drive the turntable 707 to rotate. The turntable 707 makes a circular motion, and the connecting column 706 rotates accordingly, driving the cam 705 to rotate. During the rotation of the cam 705, the arc surface of the cam 705 always remains in contact with the guide wheel 712. Through the rolling of the guide wheel 712 along the arc surface of the cam 705, the compressed spring 711 provides a force towards the cam 705 direction for the movable rod 709. The guide wheel 712 always rolls along the arc surface of the cam 705, pushing the movable rod 709 to move back and forth, so that the clamped connecting rod 1003 reciprocates along the insertion groove 504, and the disc 1001 reciprocates in the inner ring groove 501. The dredging column 1002 passes through the holes on the hole plate 600 multiple times back and forth, and the residues in the holes are cleaned by multiple penetrations.

[0084] When scraping and cleaning the inner side of the hole plate 600, the connecting rod 1003 is rotated downward toward the disc 1001 side of the dredging column 1002. The abutting elastic piece 1007 is squeezed by the rotated connecting rod 1003, and the arched section of the abutting elastic piece 1007 is separated from the abutting groove 10031, and the connecting rod 1003 is rotated and adjusted to the horizontal state. One side of the arc-shaped scraping strip 1011 with the disc 1001 can be pushed into the sleeve 500. The connecting rod 1003 is in the horizontal and outward state until it completely contacts the inner side of the hole plate 600. The scraping side end face of the arc-shaped scraping strip 1011 contacts the inner side of the hole plate 600 earlier than the outer end face of the round block 1005. The continuous thrust causes the arc-shaped elastic piece 1012 to be squeezed, and the rebounding force generated by the squeezed arc-shaped elastic piece 1012 makes the scraping side end face of the arc-shaped scraping strip 1011 closely adhere to the inner side of the hole plate 600. The connecting rod 1003 is used as a handle to drive the disc 1001 to make a circular motion in the insertion groove 504, and the scraping side of the arc-shaped scraping strip 1011 that closely adheres to the inner side of the hole plate 600 scrapes and cleans the inner side of the hole plate 600.

[0085] After completing the cleaning of the hole plate 600, the scraps cleaned are disposed of, and the dredging mechanism 1000 is taken out. The screw rod is retracted by the motor, driving the sleeve 500 to move toward the discharge end of the meat grinder cylinder 300 until the sleeve 500 covers the discharge end of the meat grinder cylinder 300, and the blocking block 901 blocks the insertion groove 504.
