Description

Technical Field

[0001] The invention relates to the technical field of processing machines, in particular to a pet puffed sandwich grain processing machine. Background Art

[0002] The pet puffed sandwich food processing machine is a device specially designed for the production of pet food (such as dog food, cat food, etc.). It mainly converts mechanical energy into thermal energy. The heat generated by the rotation of the machine extrudes and matures the food, and is formed through a specific mold to form puffed pet food with a sandwich structure.

[0003] Pet food puffing is the process in which the raw materials are subjected to high temperature and high pressure inside the puffing machine, causing physical and chemical changes, expansion in volume, and a crispy texture. After being formed into a mold, puffed pet food with a specific shape and sandwich structure is formed. However, during the puffing process, the raw materials themselves will contain a certain amount of moisture, which may be partially evaporated due to the high temperature and high pressure during the puffing process, but may also remain due to improper process control. In addition, steam is usually used in the puffing process to provide the necessary heat and pressure to cause the raw materials to expand and form the desired shape and taste. The introduction of steam may increase the humidity of the pet food.

[0004] In the prior art, when removing moisture from pet food after puffing, the puffed pet food is usually dried and cooled using a fan. However, the puffed pet food may be wet on the surface, and when being discharged from the discharge port of the puffing machine, the pet food may pile up, and the piled wet pet food is prone to stick to each other, resulting in the pet food being unable to fully contact with the flowing air, thereby affecting the subsequent drying.

[0018] Compared with the prior art, the present invention has the following significant advantages:

[0019] First, the present invention drives the rotating plate to rotate through the auger rod, thereby driving the eccentric shaft to rotate, and then driving the slip ring to reciprocate up and down. The slip ring will drive the reciprocating motion of rack one and rack two. The reciprocating motion of rack one and rack two can drive the reciprocating rotation of gear one and gear two. The reciprocating rotation of gear one cooperates with the half gear ring on the drum to realize the reciprocating swing of the drum to realize swinging feeding, thereby increasing the feeding area and thus improving the feeding uniformity. When gear two reciprocates, the slide cylinder realizes reciprocating movement under the guidance of the reciprocating guide groove through the ball bearing. The reciprocating movement of the slide cylinder can drive the two right-angle rods and the screen frame to realize reciprocating movement. The reciprocating screen frame and the swinging feeding cylinder can further improve the feeding uniformity and avoid accumulation and agglomeration.

[0020] Secondly, when the material discharge barrel of the present invention reciprocates, it can push the two driving plates, thereby driving the sliding frame to reciprocate and slide inside the dovetail groove provided on the screen frame. When the sliding frame reciprocates, the scraping plate arranged at the bottom can realize the scraping and leveling of the pet food on the screen frame, thereby avoiding the existence of repeated material discharge areas due to swinging material discharge, which leads to the accumulation of pet food; when the driving plate drives the sliding frame to reciprocate and slide, it will drive the telescopic piston to reciprocate and slide inside the fixed barrel, and cooperate with the suction pipe, bellows, connecting pipe and one-way valve, so that the gas can be transported to the inside of the sliding frame through the connecting pipe and blown out through the blowing pipe. When the sliding frame drives the scraping plate to reciprocate and level, the pet food just discharged after puffing can be cooled, thereby avoiding the hot and humid pet food from drying inside the drying box. The high temperature environment may accelerate the evaporation and migration of water in the pet food, leading to the problem of agglomeration in local humid places;

[0021] Thirdly, the reciprocating movement of the connecting rod in the present invention drives the two barrel cavities, the right-angle piston rod and the roller brush to reciprocate synchronously. The roller brush can clean the mesh on the perforated conveyor belt to prevent pet food debris from adhering to the mesh and causing it to adhere to the surface of the pet food that has just fallen onto the perforated conveyor belt during circulation, thereby affecting the quality of the pet food. At the same time, it can prevent the mesh from being blocked and affecting the drying effect. While the barrel cavity drives the right-angle piston rod to move, the squeezing ball will continuously squeeze the fixed ball, the spring will contract, and drive the right-angle piston rod to rise, so that the air inside the barrel cavity can be blown out through the air outlet pipe, and the inside of the perforated conveyor belt can be blown to further improve the cleaning effect.

[0022] The invention solves the problem that the surface of the existing puffed pet food is wet and is prone to accumulation and agglomeration during discharging. BRIEF DESCRIPTION OF THE DRAWINGS

The fixed balls 710 are linearly arrayed on the fixed plates 709 with equal intervals, which can realize the reciprocating extrusion of the squeezing balls 711, thereby realizing the reciprocating sliding of the right-angle piston rod 704. The surfaces of the two right-angle piston rods 704 are fixedly connected with squeezing balls 711.

[0048] like Figure 2 As shown, the inner wall of the drying box 1 is provided with an open conveyor belt 9, the inner bottom wall of the drying box 1 is provided with a collecting box 10, a discharge door 11 is rotatably provided on one side of the drying box 1, and a cutter 15 is fixedly connected to the surface of the auger rod 13, and the cutter 15 is fitted to one side of the extrusion die 14.

[0049] The specific working method is as follows: when in use, the pet food puffed by the puffing machine 3 is cut by the extrusion die 14 in cooperation with the cutter 15, and the cut pet food falls into the drum 401. The rotation of the auger rod 13 during puffing and extrusion can drive the cutter 15 and the rotating plate 402 to rotate synchronously, and the rotation of the rotating plate 402 drives the eccentric shaft 403 to rotate, thereby driving the slip ring 404 to reciprocate up and down under the limit of the limit groove 405 and the limit block 406. The up and down reciprocating motion of the slip ring 404 will drive the reciprocating motion of the rack 1 407 and the rack 2 611, and the reciprocating motion of the rack 1 407 and the rack 2 611 can drive the reciprocating rotation of the gear 1 408 and the gear 2 608. The reciprocating rotation of the half gear ring 409 on the drum 401 can realize the reciprocating swing of the drum 401 to realize swing feeding, increase the feeding area, and further improve the feeding uniformity; when the gear 2 608 reciprocates, it can drive the rotating rod 607 and the rotating drum 609 to rotate, and then realize the reciprocating movement of the slide 605 under the guidance of the reciprocating guide groove 610 through the ball 606, and the reciprocating movement of the slide 605 can drive the two right-angle rods 604 and the screen frame 601 to realize reciprocating movement, and the reciprocating screen frame 601 and the swinging feeding drum 410 can further improve the feeding uniformity, and the mesh on the screen frame 601 can increase the speed at which the pet food falls onto the perforated conveyor belt 9 to avoid accumulation;

[0050] When the material discharge barrel 410 swings back and forth, it can push the two driving plates 505, thereby driving the sliding frame 501 to slide back and forth inside the dovetail groove 603 opened on the screen frame 601. When the sliding frame 501 slides back and forth, the scraping plate 503 arranged at the bottom can scrape the pet food on the screen frame 601 to avoid the existence of repeated material discharge areas during swinging material discharge, which leads to the accumulation of pet food. When the driving plate 505 drives the sliding frame 501 to slide back and forth, it will drive the telescopic piston 508 to slide back and forth inside the fixed barrel 507, and cooperate with the suction pipe 509, the bellows 510, The connecting pipe 506 and the one-way valve 511 can realize that the gas is transported to the inside of the sliding frame 501 through the connecting pipe and blown out through the blowing pipe 504. When the sliding frame 501 drives the scraping plate 503 to scrape back and forth, the pet food that has just been puffed can be cooled, thereby preventing the hot and humid pet food from drying inside the drying box 1. The high temperature environment may accelerate the evaporation and migration of water in the pet food, resulting in the problem of agglomeration in local humid places. After passing through the screen frame 601 and reaching the perforated conveyor belt 9, the dried pet food can be transported to the collection box 10 for collection;

[0051] After collection, the circulating perforated conveyor belt 9 will rotate to the roller brush 705 area, and the reciprocating slide cylinder 605 will synchronously drive the right-angle rod 604 and the connecting rod 701 to move synchronously. The reciprocating movement of the two connecting rods 701 will drive the two cylinder chambers 702, the right-angle piston rod 704 and the roller brush 705 to reciprocate synchronously. The roller brush 705 can clean the mesh on the perforated conveyor belt 9 to prevent pet food debris from adhering to the mesh, causing it to adhere to the surface of the pet food that has just fallen to the perforated conveyor belt 9 during circulation, affecting the quality of the pet food. At the same time, it can prevent the mesh from being blocked and affecting the drying effect. The cylinder chamber 702 drives the right-angle piston rod While 704 moves, the squeezing ball 711 will continuously squeeze the fixed ball 710, and the spring 703 will contract, driving the right-angle piston rod 704 to rise, so that the air inside the cylinder cavity 702 can be blown out through the air outlet pipe 707, and the inside of the perforated conveyor belt 9 is blown to further improve the cleaning effect. After the squeezing ball 711 is separated from the fixed ball 710, the spring 703 is reset, driving the right-angle piston rod 704 to reset. When moving back and forth, a vibration effect of the rolling brush 705 can be formed to improve the cleaning effect. At the same time, when the spring 703 is reset, air can be re-absorbed through the air inlet pipe 706 to achieve fixed frequency and continuous blowing.
