Description

Technical Field

[0001] This utility model relates to the field of feed processing, and in particular to feed extrusion molding structures. Background Technology

[0002] In the feed processing and production process, after the feed is extruded and shaped, it usually needs to be cut to obtain feed products that meet the specified length. At present, there are some prominent problems in the operation of feed cutting equipment on the market.

[0003] In terms of feed cutting, existing equipment drives related structures to move up and down in the cavity through a drive component, squeezing air in the cavity into a specific component to drive the cutting structure. However, in this process, the feed often ends up being cut into different lengths, making it difficult to ensure the consistency of feed length. This affects the quality stability of feed products and causes inconvenience to subsequent packaging, transportation and feeding processes. Meanwhile, in terms of controlling the feed cutting length, existing equipment lacks effective adjustment methods. Because it is impossible to precisely adjust the pre-tightening force that affects the triggering of the cutting action, it is difficult to accurately control the length of the feed that is squeezed out and accumulated according to actual needs. Consequently, it is impossible to accurately adjust the final cutting length of the feed. In existing equipment, the tension of the components used to provide pre-tightening force is difficult to change conveniently and accurately, which makes it impossible to effectively control the pressure stroke time or number of times required by the drive components. This makes it impossible to flexibly adapt to the production needs of feed of different specifications and lengths, thus limiting the applicability and flexibility of the equipment. Utility Model Content

[0004] The purpose of this utility model is to provide a feed extrusion molding structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a feed extrusion molding structure, including a crushing component for crushing feed raw materials and a conveying and extruding component for conveying and extruding feed raw materials. The conveying and extruding component and the crushing component are mounted together on a fixed frame and are connected to each other. A molding die component is installed on the side of the conveying and extruding component away from the crushing component. A pushing component for controlling the feed cutting length is installed on the molding die component. A driving component for driving the conveying and extruding component, the crushing component and the pushing component to work together is installed on the crushing component. The forming mold assembly includes a sleeve installed at the discharge port of the conveying extrusion assembly. The sleeve has two semi-circular guide grooves, and a forming template and a cutting template are respectively inserted into the inner side of the two semi-circular guide grooves. The pushing component includes a mounting base fixedly installed on the lower side of the sleeve. Air cylinder one and air cylinder two are fixedly installed on the mounting base respectively. Piston two, which is driven by the driving component, is slidably installed inside air cylinder two. Piston one is slidably installed inside air cylinder one. A connecting block is fixedly connected between piston one and the cutting template. A threaded push rod is threaded through the top of the first air cylinder. A spring is installed inside the first air cylinder. The two ends of the spring abut against the threaded push rod and the first piston. A guide groove is opened through the outside of the first air cylinder to allow the connecting block to slide. A one-way valve is installed at the connection between the first air cylinder and the second air cylinder.

[0006] As a further description of the above technical solution: the crushing assembly includes a cylinder seat fixedly installed on the fixed frame, a feeding hopper is installed at the upper port of the cylinder seat, and a double roller crusher is rotatably installed on the upper side of the inner cavity of the cylinder seat.

[0007] As a further description of the above technical solution: the conveying and extrusion assembly includes a conveying pipe fixedly installed on the fixed frame, the conveying pipe extending through to the inner side of the cylinder seat, a conveying shaft rotatably installed at the axial center of the inner side of the conveying pipe, and a conveying blade adapted to the inner side of the conveying pipe installed on the outer side of the conveying shaft.

[0008] As a further description of the above technical solution: the drive assembly includes a servo motor mounted on the cylinder base and a pulley one mounted on the rotating shaft of the roller crusher. The output shaft of the servo motor is fixedly connected to the conveying shaft through a coupling. A pulley two is fixedly mounted on the outside of the output shaft of the servo motor. A transmission belt is connected between the pulley two and the pulley one.

[0009] As a further description of the above technical solution: the sleeve is sleeved on the outside of the discharge port of the conveying pipe, and the sleeve is fixedly connected to the conveying pipe through a flange. The forming template is tightly attached to the discharge port of the conveying pipe. The cutting template is coaxial with the forming template and is opposite to it. The forming template and the cutting template are respectively provided with slots at their axial centers for the conveying shaft to pass through.

[0010] As a further description of the above technical solution: a turntable is fixedly installed on one end of the conveying shaft that passes through the cutting template, a connecting rod is fixedly installed on the top end of the piston, and a hinge rod is rotatably connected between the connecting rod and the outer side of the turntable away from the axis.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: The piston in cylinder two is driven to move up and down reciprocally by the drive assembly. This causes the piston to force the air in cylinder two into cylinder one through a one-way valve. The piston in cylinder one is squeezed by the spring tension. As the piston continues to pressurize, when the output air pressure is greater than the tension of the spring on piston one, piston one drives the cutting template to move upward through the connecting block. This causes the discharge hole on the cutting template to intersect with the discharge port on the forming template, thereby cutting the feed between the discharge holes of the forming template and the cutting template. This effectively avoids the situation of feed of different lengths and enhances the consistency of the length of the feed after extrusion. Rotating the spring downwards causes it to compress and deform, increasing the preload applied to piston one. As a result, when the drive assembly drives piston two to pressurize, piston two requires a longer or more pressurization strokes to push piston one to overcome the increased preload and drive the cutting template to perform the cutting action. Therefore, by adjusting the pressure applied to the spring by the threaded push rod, the length of the extruded and accumulated feed can be precisely controlled, thereby adjusting the final cut length of the feed.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] like Figure 1 - Figure 2 As shown, the present invention provides a feed extrusion molding structure, including a crushing component 3 for crushing feed raw materials and a conveying and extruding component 2 for conveying and extruding feed raw materials. The conveying and extruding component 2 and the crushing component 3 are installed together on a fixed frame 1 and are connected to each other. A molding die component 5 is installed on the side of the conveying and extruding component 2 away from the crushing component 3. A pushing component 6 for controlling the feed cutting length is installed on the molding die component 5. A driving component 4 for driving the conveying and extruding component 2, the crushing component 3 and the pushing component 6 to work together is installed on the crushing component 3. In actual use, the crushing component 3 breaks down the extruded feed raw materials, eliminating the interference of large lumps of raw materials on subsequent processes. The raw materials crushed by the crushing component 3 are then conveyed directionally to the forming mold component 5 via the conveying extrusion component 2. Through the synergistic extrusion action of the conveying extrusion component 2 and the forming mold component 5, the feed is extruded and compacted into shape. Finally, the pushing component 6 precisely controls the fixed-length cutting of the formed feed.

[0016] Specifically, such as Figure 2 As shown, the crushing assembly 3 includes a cylinder seat 31 fixedly installed on the fixed frame 1, a feeding hopper 32 installed at the upper port of the cylinder seat 31, and a double roller crusher 33 rotatably installed on the upper side of the inner cavity of the cylinder seat 31. The conveying and extrusion assembly 2 includes a conveying pipe 21 fixedly installed on the fixed frame 1. The conveying pipe 21 extends through to the inside of the cylinder seat 31. A conveying shaft 22 is rotatably installed at the axial center of the inner side of the conveying pipe 21. A conveying blade 23 adapted to the inner side of the conveying pipe 21 is installed on the outer side of the conveying shaft 22. When the feed ingredients are poured into the cylinder seat 31 through the feeding hopper 32, the roller crusher 33 is driven by the drive component 4 to rotate, thereby crushing the large pieces of feed ingredients. As the drive component 4 is driven, the conveying blade 23 on the outside of the conveying shaft 22 rotates, conveying the crushed feed ingredients to the forming mold component 5 and extruding them into shape.

[0017] Furthermore, such as Figure 3As shown, the drive assembly 4 includes a servo motor 41 mounted on the cylinder base 31 and a pulley 43 mounted on the rotating shaft of the roller crusher 33. The output shaft of the servo motor 41 is fixedly connected to the conveying shaft 22 through a coupling. A second pulley 42 is fixedly mounted on the outside of the output shaft of the servo motor 41. A transmission belt 44 is connected between the second pulley 42 and the first pulley 43. Start the servo motor 41, which drives the conveyor shaft 22 to rotate the conveyor blade 23 to convey the feed raw materials. The output shaft of the servo motor 41 drives the roller crusher 33 to rotate through the second pulley 42 and the first pulley 43 to crush large pieces of feed raw materials.

[0018] Specifically, such as Figure 4 As shown, the forming mold assembly 5 includes a sleeve 51 installed at the discharge port of the conveying extrusion assembly 2. Two semi-circular guide grooves 52 are provided on the sleeve 51. A forming template 53 and a cutting template 54 are respectively inserted into the inner side of the two semi-circular guide grooves 52. The sleeve 51 is fitted on the outside of the discharge port of the conveying pipe 21, and the sleeve 51 is fixedly connected to the conveying pipe 21 through the flange. The forming template 53 is tightly attached to the discharge port of the conveying pipe 21. The cutting template 54 is coaxial with the forming template 53 and opposite to it. The forming template 53 and the cutting template 54 are respectively provided with slots for the conveying shaft 22 to pass through. As the conveyor blade 23 continuously conveys, the feed raw materials are squeezed into the sleeve 51 and then squeezed into shape through the discharge hole on the forming template 53. The forming template 53 is inserted into the corresponding semi-circular guide groove 52, which makes it convenient to replace different styles of forming template 53. When the drive assembly 4 drives the conveying and extrusion assembly 2 to rotate and convey feed raw materials, it pushes the cutting template 54 by pushing the push assembly 6. This causes the discharge hole on the cutting template 54 to be staggered with the discharge port on the forming template 53, thereby cutting the feed passing between the discharge hole of the forming template 53 and the cutting template 54.

[0019] Furthermore, such as Figure 5 As shown, the pushing component 6 includes a mounting base 61 fixedly installed on the lower side of the sleeve 51. Air cylinder 1 63 and air cylinder 2 64 are fixedly installed on the mounting base 61 respectively. Piston 2 641, which is driven by the driving component 4, is slidably installed inside air cylinder 2 64. Piston 1 633 is slidably installed inside air cylinder 1 63. A connecting block 632 is fixedly connected between piston 1 633 and cutting template 54. A threaded push rod 635 is threaded through the top of the air cylinder 63. A spring 634 is installed inside the air cylinder 63. The two ends of the spring 634 abut against the threaded push rod 635 and the piston 633. A guide groove 631 is opened through the outside of the air cylinder 63 to allow the connecting block 632 to slide. A one-way valve 66 is installed at the connection between the air cylinder 63 and the air cylinder 64. A turntable 621 is fixedly installed on one end of the conveying shaft 22 that passes through the cutting template 54. A connecting rod 642 is fixedly installed on the top of the piston 641. A hinge rod 65 is rotatably connected between the connecting rod 642 and the outer side of the turntable 621 away from the axis. When the conveying shaft 22 rotates, it drives the turntable 621 to rotate. When the turntable 621 rotates, it pushes and pulls the piston 641 in the second air cylinder 64 back and forth through the hinge rod 65. In this way, the piston 641 forces the air in the second air cylinder 64 into the first air cylinder 63 through the one-way valve 66. The piston 633 in the first air cylinder 63 is squeezed by the tension of the spring 634. As the piston 641 continues to pressurize, when the output air pressure is greater than the tension of the spring 634 on the piston 633, the piston 633 drives the cutting template 54 to move upward through the connecting block 632, thereby cutting the feed passing between the forming template 53 and the discharge hole of the cutting template 54. Rotating 653 causes it to press down on the spring 634. After the spring 634 is compressed and deformed, the preload force it applies to the piston 633 increases. Thus, when the drive assembly 4 drives the piston 641 to pressurize, the piston 641 needs a longer time or more pressurization strokes to push the piston 633 to overcome the increased preload force and drive the cutting template 54 to perform the cutting action. Therefore, by adjusting the pressure applied by the threaded push rod 635 to the spring 634, the length of the feed that is squeezed out and accumulated can be precisely controlled, thereby adjusting the final length of the cut feed.

[0020] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
