[0008] Further description, the placement component includes an electric turntable installed at the bottom of the cylinder. The top of the electric turntable is at the same level as the top of the cylinder. Feeding cylinders are fixedly inserted through the electric turntable at circumferentially evenly spaced intervals for placing pet food. A limiting plate is rotatably connected to the bottom of the feeding cylinder to limit the pet food in the feeding cylinder. A return spring is connected between the limiting plate and the feeding cylinder. A support frame is fixedly connected to the inner side of the cylinder and is used to drive the limiting plate to swing to close the inside of the feeding cylinder.

[0009] Further description, the feeding component includes a housing communicated with the bottom of the loading cylinder. A feeding roller is rotatably inserted through the two sides of the housing to drive the pet food to rotate for feeding. A stepping motor is installed on the outer side of the housing, and the end of the output shaft of the stepping motor is fixedly connected to the end of the feeding roller. A discharge pipe is communicated with the bottom of the housing, and the discharge port of the discharge pipe faces the feeding cylinder. An annular plate is fixedly connected to the top of the cylinder, and the annular plate is fixedly connected to the discharge pipe. A level sensor is fixedly inserted through the annular plate, and the level sensor is electrically connected to the stepping motor.

[0010] Further description, a quarter position of the feeding roller is a groove for loading a fixed amount of pet food.

[0011] Further explanation, the compression molding device for pet food production also includes a limiting material component, which includes a limiting material frame that is vertically slidably connected to the compression rod to limit the compressed pet food. The lower part of the limiting material frame slides through the bottom of the compression rod. A supporting spring is connected between the limiting material frame and the compression rod. The front and rear sides of the compression rod are fixedly connected to the limiting frame, and the left and right sides of the limiting frame are inclined surfaces. A locking assembly is provided on the compression rod to limit the limiting material frame.

[0012] Further explanation, the locking assembly includes vertical shafts evenly spaced and fixed to the outside of the compression rod, a movable plate is slidably mounted between the vertical shafts, a compression spring II is connected between the movable plate and the vertical shaft, blocks are symmetrically slidably connected to the front and rear sides of the movable plate to limit the position of the material limit frame, a compression spring III is connected between the block and the movable plate, the top of the block is an inclined surface, the bottom of the block is in contact with the inclined surface of the limit frame, a groove is provided on the block, vertical rods are fixed to the front and rear sides of the movable plate, the vertical rods move downward and contact the annular plate.

[0013] Further explanation, the compression molding device for pet feed production also includes an air jet pipe fixedly connected to the annular plate, the air jet pipe is located above the discharge frame, the air jet pipe is connected to an air inlet pipe, the air inlet pipe is fixedly connected to the cylinder, and the air inlet pipe is used to connect to an external air pump.

[0014] The beneficial effects of the present invention are: 1. First, a fixed amount of pet feed is discharged into the discharge barrel through the material conveying roller. The discharge barrel rotates forward to drive the pet feed to rotate forward to the bottom of the compression rod. Then, the electric screw is started to rotate forward, so that the compression rod moves downward to the discharge barrel to compress the pet feed. Whenever the compression rod moves upward to reset, the drive motor is started to make the brush plate rotate and contact the bottom end of the compression rod. The brush plate removes the pet feed attached to the bottom end of the compression rod to prevent the pet feed from attaching and affecting the flatness of the subsequent compression molding of the compression rod, thereby improving the quality of the compression molding of the pet feed.

[0015] 2. Under the action of the limiting rack, every time the compression rod compresses the pet food into shape, the limiting rack can limit the block pet food, and the compression rod continues to move upward to break away from the block pet food, which can prevent the compressed pet food from sticking to the bottom of the compression rod and being lifted up to affect the discharge, thereby ensuring the smooth separation of the compressed pet food from the compression rod.

[0016] 3. Under the action of the jet pipe, whenever the limit plate swings back to its original position and breaks away from the contact with the block pet feed, the jet pipe can spray out air, and the sprayed air blows the block pet feed downward for discharge, which can prevent the block pet feed from getting stuck in the discharge barrel and being difficult to discharge, thereby ensuring the smooth discharge of the block pet feed.

The rotating shaft 11 drives the brush plate 12 to rotate. The rotation of the brush plate 12 contacts the bottom end of the compression rod 8, so that the brush plate 12 clears the pet food attached to the bottom end of the compression rod 8, and the collection box 121 collects the cleared pet food.

[0032] Please refer to Figure 3 and Figure 4As shown in the figure, the placing component includes an electric turntable 9, a feeding cylinder 91, a limiting plate 92, a return spring 93 and a support frame 94. An electric turntable 9 is installed in the middle of the bottom of the cylinder body 2. The top of the electric turntable 9 is at the same level as the top of the cylinder body 2. The feeding cylinders 91 are fixedly connected in a circumferentially evenly spaced manner through the electric turntable 9. The feeding cylinder 91 can be used to place pet food. The bottom of the feeding cylinder 91 is rotatably connected to a limiting plate 92. The limiting plate 92 can limit the pet food in the feeding cylinder 91. A return spring 93 is connected between the outer side surface of the limiting plate 92 and the feeding cylinder 91. A support frame 94 is fixedly connected to the rear side of the inner bottom of the cylinder body 2. When the limiting plate 92 contacts the inner side of the support frame 94, the support frame 94 can drive the limiting plate 92 to swing upward to seal the inside of the feeding cylinder 91.

[0033] Please refer to Figures 6-8 As shown in the figure, the discharging component includes a housing 15, a stepping motor 151, a discharging pipe 152, a material level sensor 153, a material transporting roller 154 and an annular plate 155. The left side of the bottom of the loading cylinder 3 communicates with a housing 15. A material transporting roller 154 is rotatably connected through the front and rear sides of the housing 15. When the material transporting roller 154 rotates, the material transporting roller 154 can drive the pet food to rotate for material transportation. A quarter position of the material transporting roller 154 is a groove for loading a fixed amount of pet food. A stepping motor 151 is installed on the outer front side of the housing 15. The end of the output shaft of the stepping motor 151 is fixedly connected to the front end of the material transporting roller 154. The bottom of the housing 15 communicates with a discharging pipe 152. The discharging port of the discharging pipe 152 faces the feeding cylinder 91. An annular plate 155 is fixedly connected to the top of the cylinder body 2. The annular plate 155 is fixedly connected to the outer side surface of the discharging pipe 152. A material level sensor 153 is fixedly connected through the left front side of the annular plate 155. The material level sensor 153 is electrically connected to the stepping motor 151.

[0034] First, pour an appropriate amount of pet feed into the loading barrel 3, and the appropriate amount of pet feed in the loading barrel 3 falls into the groove of the conveying roller 154 through the shell 15, and then start the electric turntable 9 to intermittently rotate forward, and the electric turntable 9 rotates sixty degrees each time, and the intermittent forward rotation of the electric turntable 9 drives the discharge barrel 91 to intermittently rotate forward, and the discharge barrel 91 drives the limit plate 92 to rotate forward. When the limit plate 92 rotates forward and contacts the inner side of the support frame 94, the support frame 94 drives the limit plate 92 to swing upward, and the reset spring 93 is stretched, and the limit plate 92 swings upward to close the discharge barrel 91. When the discharge barrel 91 passes under the material level sensor 153 and corresponds to the discharge port of the discharge pipe 152, the material level sensor 153 controls the stepper motor 151 to start rotating forward ninety degrees, and the stepper motor 151 drives the conveying roller 15 4 rotates forward 90 degrees, the material conveying roller 154 rotates forward to drive the pet feed to rotate forward to the bottom, and the pet feed is discharged from the shell 15 into the discharge pipe 152, and the pet feed in the discharge pipe 152 is discharged into the corresponding discharge barrel 91, and then the stepper motor 151 is reversed 90 degrees to reset, and an appropriate amount of pet feed in the charging barrel 3 falls into the groove of the material conveying roller 154 through the shell 15 again, and this is repeated. Through the groove setting of the material conveying roller 154, a fixed amount of pet feed can be continuously discharged into the discharge barrel 91, and the discharge barrel 91 rotates forward through the limit plate 92 to drive the pet feed to rotate forward. When the pet feed in the discharge barrel 91 rotates forward to the bottom of the compression rod 8, the electric turntable 9 is turned off, and the electric screw 6 is started to rotate forward to drive the lifting plate 7 to move downward, and the lifting plate 7 drives the compression rod 8 to The lifting plate 7 moves downward, and the lifting plate 7 drives the sliding frame 10 to move downward through the connecting spring 13, and the sliding frame 10 drives the brush plate 12 and the collecting frame 121 to move downward through the rotating shaft 11, and the collecting frame 121 moves downward and contacts the annular plate 155 and is limited, and the collecting frame 121 stops moving downward, and the collecting frame 121 stops the rotating shaft 11 and the sliding frame 10 from moving downward, and the lifting plate 7 continues to move downward to compress the connecting spring 13, and at this time the compression rod 8 moves downward to the discharge barrel 91 just below and contacts the pet feed, and the compression rod 8 cooperates with the discharge barrel 91 to compress the pet feed into a block shape, and the electric screw 6 can be started to reverse and drive the lifting plate 7 to move upward and reset, and the lifting plate 7 drives the compression rod 8 to move upward and reset, and the lifting plate 7 moves upward First, the connecting spring 13 is reset, and then the lifting plate 7 drives the sliding frame 10 to move upward and reset through the connecting spring 13. The sliding frame 10 drives the collecting frame 121 and the brush plate 12 to move upward and reset through the rotating shaft 11, and the driving motor 14 can be started. The driving motor 14 drives the rotating shaft 11 to rotate through the synchronous belt assembly. The rotating shaft 11 drives the brush plate 12 and the collecting frame 121 to rotate. The brush plate 12 rotates and contacts the bottom end of the compression rod 8. The brush plate 12 removes the pet food attached to the bottom end of the compression rod 8 to prevent the pet food from attaching and affecting the flatness of the subsequent compression molding of the compression rod 8, thereby improving the quality of the compression molding of the pet food. The removed pet food falls into the collecting frame 121. When the pet food attached to the bottom end of the compression rod 8 is removed, the driving motor 14 is turned off.The brush plate 12 and the collection box 121 stop rotating. Then, the feeding cylinder 91 continues to rotate forward, driving the compressed and formed block-shaped pet food and the limiting plate 92 to rotate forward. The limiting plate 92 rotates forward and disengages from the support frame 94. Due to the action of the return spring 93, the limiting plate 92 swings downward to reset, and the limiting plate 92 disengages from the block-shaped pet food. The block-shaped pet food falls from the feeding cylinder 91 into the discharge frame 5, and the block-shaped pet food in the discharge frame 5 is discharged from the discharge frame 5 for collection. This process is repeated. Whenever the feeding cylinder 91 drives the pet food to rotate forward to directly below the compression rod 8, the compression rod 8 compresses the pet food into a formed shape.

[0035] Please refer to Figures 9-11 As shown in the figure, the compression molding device for pet food production further includes a material limiting component installed on the compression rod 8. The material limiting component includes a locking component, a limiting frame 1641, a material limiting frame 165, and a support spring 166. The material limiting frame 165 is vertically and slidably connected to the compression rod 8. The material limiting frame 165 can limit the compressed and formed pet food. The lower part of the material limiting frame 165 slidably penetrates the bottom of the compression rod 8. A support spring 166 is connected between the lower part of the material limiting frame 165 and the inner side of the compression rod 8. Limiting frames 1641 are fixedly connected to the lower parts on both the front and rear sides of the compression rod 8. The left and right sides of the limiting frame 1641 are inclined planes. A locking component is arranged on the compression rod 8. When the locking component operates, the locking component can limit the material limiting frame 165. The locking component includes a movable plate 16, a compression spring II 161, a vertical shaft 1611, a clamping block 162, a vertical rod 163, and a compression spring III 164. Four vertical shafts 1611 are evenly and spacedly fixedly connected to the outer side of the compression rod 8. A movable plate 16 is slidably connected between the four vertical shafts 1611. A compression spring II 161 is connected between the top of the movable plate 16 and the upper part of the vertical shaft 1611. Clamping blocks 162 are slidably connected to both the front and rear sides of the movable plate 16 in a left-right symmetric manner. Two compression springs III 164 are connected between the mutually remote sides of the left and right clamping blocks 162 and the inner side surface of the movable plate 16. The clamping block 162 can limit the material limiting frame 165. The top of the clamping block 162 is an inclined plane, and the bottom of the clamping block 162 contacts the inclined plane of the limiting frame 1641. Grooves are opened in the upper parts of the mutually approaching sides of the left and right clamping blocks 162. Vertical rods 163 are fixedly connected to the middle parts of both the front and rear sides of the movable plate 16. The vertical rods 163 move downward to contact the annular plate 155.

[0036] Initially, the compression spring III 164 is in a compressed state. When the compression rod 8 moves downward, the compression rod 8 drives the movable plate 16 to move downward through the compression spring II 161. The movable plate 16 drives the vertical rod 163 and the clamping block 162 to move downward. When the vertical rod 163 moves downward and contacts the annular plate 155, the annular plate 155 limits the vertical rod 163, and the vertical rod 163 stops moving downward. The vertical rod 163 causes the movable plate 16 to stop moving downward, and the movable plate 16 causes the clamping block 162 to stop moving downward. The compression rod 8 also drives the limit frame 1641 to move downward, and the limit frame 1641 moves downward and disengages from the clamping block 162. Due to the action of the compression spring III 164, the clamping blocks 162 on the left and right sides move toward each other and contact each other. At the same time, the compression rod 8 continues to move downward to compress the compression spring II 161, and the compression rod 8 drives the material limiting frame 165 to move downward through the support spring 166. When the material limiting frame 165 moves downward and contacts the inclined surface of the clamping block 162, the material limiting frame 165 squeezes the clamping blocks 162 on the left and right sides to move away from each other, and the compression spring III 164 is compressed. When the material limiting frame 165 moves downward to correspond to the groove of the clamping block 162, due to the action of the compression spring III 164, the clamping blocks 162 on the left and right sides move toward each other to lock the material limiting frame 165. At the same time, the screw rod 6 stops rotating. At this time, the compression rod 8 has completed the compression molding of the pet food. The material limiting frame 165 contacts the compression-molded pet food. When the compression rod 8 moves upward to reset, the compression rod 8 causes the compression spring II 161 to reset. Due to the locking of the material limiting frame 165 by the clamping block 162, the compression rod 8 moves upward to compress the support spring 166, and the material limiting frame 165 limits the compression-molded pet food. The compression rod 8 moves upward to drive the limit frame 1641 to move upward. When the limit frame 1641 moves upward and contacts the clamping block 162, the limit frame 1641 drives the clamping blocks 162 on the left and right sides to move away from each other and reset, and the compression spring III 164 is compressed. The clamping block 162 resets to release the material limiting frame 165. Due to the action of the support spring 166, the material limiting frame 165 moves upward and resets and retracts into the compression rod 8. In this way, it can prevent the compression-molded pet food from sticking to the bottom end of the compression rod 8 and being lifted, which affects the discharging, so as to ensure the smooth separation of the compression-molded pet food from the compression rod 8.

[0037] Please refer to Figure 12 As shown, the compression molding device for pet food production further includes an air spray pipe 17 and an air inlet pipe 18. The air spray pipe 17 is fixedly penetrated through the front side of the annular plate 155. The air spray pipe 17 is located above the discharge frame 5. The top of the air spray pipe 17 is communicated with the air inlet pipe 18. The air inlet pipe 18 is fixedly connected to the outer front side of the cylinder body 2. The air inlet pipe 18 is used to connect an external air pump.

[0038] Initially, the air inlet pipe 18 is connected to an external air pump. When the pet food is continuously compressed and formed, the external air pump can be started to discharge air into the air inlet pipe 18. The air in the air inlet pipe 18 is discharged into the air jet pipe 17. The air jet pipe 17 sprays air into the discharge barrel 91. The air contacts the block pet food in the discharge barrel 91. The air blows the block pet food downward to assist in discharging. When all the pet food is compressed and formed, the external air pump is turned off, and the air jet pipe 17 stops spraying air. In this way, the block pet food can be prevented from being stuck in the discharge barrel 91 and difficult to be discharged, thereby ensuring the smooth discharging of the block pet food.

[0039] Finally, it is necessary to point out that the above content is only used to help understand the technical solution of the present invention and cannot be understood as limiting the scope of protection of the present invention; non-essential improvements and adjustments made by technical personnel in the field of technology based on the above content of the present invention are all within the scope of protection required by the present invention.
