Description

A clog-proof feeding device Technical Field

[0001] This utility model relates to the field of feeding device technology, specifically to a feeding device that prevents blockage. Background Technology

[0002] In the production process of functional soft pet food (such as lecithin nutritional supplements), it is usually necessary to mix various powdered raw materials (such as corn flour, defatted soybean flour, collagen, etc.) with liquid ingredients (such as molasses, lecithin) through a mixer, and then extrude them through an extruder.

[0003] Traditional feeding devices often physically connect the mixer and extruder through a single hopper. This makes it easy for materials with poor flowability to bridge in the hopper. That is, the mixed materials cannot flow smoothly under the action of gravity and form an "arch"-like accumulation in the conical section of the hopper, preventing the materials from entering the extruder smoothly and affecting continuous production. In order to reasonably improve this problem, this utility model proposes an anti-clogging feeding device. Summary of the Invention

[0004] The purpose of this invention is to address the technical problem that traditional feeding devices often only physically connect the mixer and extruder through a single hopper. This causes poorly flowing materials to easily bridge in the hopper, meaning that the mixed materials cannot flow smoothly under gravity and form an "arch"-like accumulation in the conical section of the hopper, preventing the materials from smoothly entering the extruder and affecting continuous production. This invention provides an anti-clogging feeding device.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] A clog-prevention feeding device, comprising:

[0007] The first hopper has a feeding channel connected to the top, and a material gate assembly is provided in the feeding channel to control the opening and closing of the feeding channel;

[0008] The second hopper is connected to the bottom of the first hopper. The second hopper is equipped with a bridge-breaking device to break up the bridged materials.

[0009] Multiple arch-breaking devices are respectively installed in the first and second feeding hoppers. The arch-breaking devices can loosen the material and restore it to a flowable state.

[0010] The discharge channel is connected to the bottom of the second hopper and is equipped with an auger conveyor assembly, through which materials can be output from the discharge channel.

[0011] Furthermore, the bridge-breaking device includes a rotating rod rotatably installed inside the second hopper, and multiple stirring rods are distributed around the rotating rod.

[0012] Furthermore, the arch-breaking device includes an air outlet pipe, a flexible air disc is installed around the air outlet pipe, and multiple air outlets are distributed on the air outlet pipe. The flexible air disc covers the multiple air outlets and is in contact with the inner wall of the first or second hopper.

[0013] Furthermore, the auger conveying assembly includes two auger blades arranged in parallel and interleaved with each other. The inner walls on both sides of the discharge channel are close to the periphery of the two auger blades respectively. A drive mechanism is provided on one side of the second discharge hopper to drive the two auger blades to rotate synchronously relative to each other.

[0014] Furthermore, the drive mechanism includes a mounting frame connected to the second hopper. Two meshing spur gears are rotatably mounted on the mounting frame. The shafts of the two auger blades pass through the mounting frame and are respectively connected to the two spur gears. A first motor is mounted on the mounting frame. A drive gear is mounted on the output end of the first motor. One of the spur gears is coaxially connected to a driven gear that meshes with the drive gear. The end of the rotating rod passes through the mounting frame and is connected to the other spur gear via a chain drive mechanism.

[0015] Furthermore, a stirring blade is rotatably installed inside the second hopper, located on one side of the rotating rod, and a second motor is installed on the outside of the second hopper to drive the stirring blade to rotate.

[0016] Furthermore, the material gate assembly includes a guide plate arranged in an inverted V-shape within the feeding channel. A baffle is hinged within the feeding channel, with the baffle hinge shaft passing through the feeding channel and connected to a connecting block. A brake cylinder is hinged to the outside of the feeding channel, with its output end connected to the connecting block.

[0017] Furthermore, an angle sensor is installed on the connecting block.

[0018] Furthermore, a rotary paddle level sensor is installed on the feed channel.

[0019] The beneficial effects of this utility model are as follows: By adding a material bridging device, this utility model can break up the material that is about to bridge in the second hopper, preventing the material from bridging. Then, multiple bridging devices further loosen the material and restore it to a fluid state, so that the material can be output from the discharge channel through the auger conveyor assembly. Through the cooperation of the above structures, materials with poor fluidity can be smoothly transported into the extruder, which is not likely to affect continuous production and is quite easy to use.

[0029] The present invention will now be further described with reference to the accompanying drawings.

[0030] In the accompanying drawings of this utility model, the same or similar reference numerals correspond to the same or similar components. In the description of this utility model, it should be understood that if terms such as "head," "tail," "top," "bottom," "left," "right," "front," "rear," "inner," and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, they are only for the convenience of describing this utility model, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0031] Please refer to Figure 1. One embodiment of this utility model provides an anti-clogging feeding device, comprising:

[0032] The first hopper 1 is connected to the top of the feeding channel 2, which is connected to the discharge end of the existing mixer. The feeding channel 2 is equipped with a material gate assembly 3 to control the opening and closing of the feeding channel 2.

[0033] The second hopper 4 is connected to the bottom of the first hopper 1. Under the action of gravity, the material can fall into the second hopper 4 through the first hopper 1. The second hopper 4 is equipped with a bridge breaking device 5, which breaks up the bridged material.

[0034] Multiple arch-breaking devices 6 are respectively installed in the first hopper 1 and the second hopper 4. The arch-breaking devices 6 can loosen the material and restore it to a flowable state.

[0035] The discharge channel 7 is connected to the bottom of the second hopper 4. The discharge end of the discharge channel 7 is connected to the existing extruder. The discharge channel 7 is set horizontally. The material that is broken up by the bridge breaking device 5 will enter the discharge channel 7. The auger conveyor assembly 8 is installed inside the discharge channel 7. The material can be conveyed from the discharge channel 7 to the extruder through the auger conveyor assembly 8.

[0036] This invention adds a material bridging device 5 to break up materials that are about to bridge in the second hopper 4, preventing material bridging. Then, multiple arch-breaking devices 6 further loosen the material and restore it to a fluid state, so that the material can be output from the discharge channel 7 through the auger conveyor assembly 8. Through the cooperation of the above structures, materials with poor flowability can be smoothly transported into the extruder, which is not likely to affect continuous production and is quite easy to use.

[0037] As shown in Figures 6 and 7, the specific structure of the bridge breaking device 5 of this utility model is disclosed. The bridge breaking device 5 includes a rotating rod 501 rotatably installed in the second feeding hopper 4. The rotating rod 501 is located at the top of the auger conveyor assembly 8. Multiple stirring rods 502 are distributed around the rotating rod 501. By driving the rotating rod 501 to rotate, the material in the second feeding hopper 4 can be turned over by the multiple stirring rods 502, thereby breaking up the bridging material.

[0038] As shown in Figures 4, 5, and 7, the specific structure of the arch-breaking device 6 of this utility model is disclosed. The arch-breaking device 6 includes an air outlet pipe 601. Multiple air outlet pipes 601 are connected to an existing air compressor via flexible hoses and are fixed to the inner wall of the first hopper 1 or the second hopper 4 by flanges or bolts. Flexible air discs 602 are installed around the air outlet pipes 601. The flexible air discs 602 are made of rubber and are coaxially installed at the end of the air outlet pipes 601. Multiple air outlets 603 are distributed on the air outlet pipes 601, and the flexible air discs 602 cover the multiple air outlets 603. 03, and adheres to the inner wall of the first hopper 1 or the second hopper 4. When compressed air enters the air outlet pipe 601 and is ejected from multiple air outlets 603, the flexible air disc 602 will separate from the inner wall of the first hopper 1 or the second hopper 4 under the action of the compressed air. Subsequently, the compressed air is dispersed from all sides of the flexible air disc 602. When it comes into contact with the material, it forms an "air cushion" between the materials, reducing friction and cohesion, destroying the arch structure, and causing the material to change from a static state to a dynamic flow state. This solves the arching problem caused by material adhesion and particle interlocking, and helps the material flow.

[0039] As shown in Figures 7 and 8, the specific structure of the auger conveying assembly 8 of this utility model is disclosed. The auger conveying assembly 8 includes two auger blades 801 arranged in parallel, with the blades interlacing. The inner walls on both sides of the discharge channel 7 are close to the periphery of the two auger blades 801, and the longitudinal section of the discharge channel 7 is a horizontal "figure-eight" shape. A driving mechanism 802 is provided on one side of the second hopper 4 to drive the two auger blades 801 to rotate synchronously relative to each other.

[0040] The above structure has the following advantages:

[0041] 1. The staggered blades form a continuous pushing surface, which can prevent material backflow or stagnation during the conveying process, thereby improving the conveying speed and stability;

[0042] 2. When the two blades rotate relative to each other, the intersecting area produces a "clamping" effect, which is especially suitable for sticky and easily clumped feed;

[0043] 3. The parallel layout of the twin augers can achieve a large conveying capacity in a small space, making it suitable for occasions with limited installation space.

[0044] As shown in Figures 7 and 8, the specific structure of the drive mechanism 802 of this utility model is disclosed. The drive mechanism 802 includes a mounting frame 8021 connected to the second hopper 4. Two meshing spur gears 8022 are rotatably mounted on the mounting frame 8021. The shafts of the two auger blades 801 pass through the mounting frame 8021 and are respectively connected to the two spur gears 8022. The two auger blades 801 can achieve synchronous relative rotation through the two spur gears 8022. A first motor 802 is mounted on the mounting frame 8021. 3. A drive gear 8024 is installed at the output end of the first motor 8023. One of the spur gears 8022 is coaxially connected to a driven gear 8025 that meshes with the drive gear 8024. The end of the rotating rod 501 passes through the mounting bracket 8021 and is connected to the other spur gear 8022 through a chain drive mechanism 8026. The chain drive mechanism 8026 includes a sprocket 80261 installed on the other spur gear 8022 and the end of the rotating rod 501. The two sprockets 80261 are connected through a chain 80262.

[0045] As can be seen from the above, when the first motor 8023 is working, it can drive the driven gear 8025 to rotate through the drive gear 8024. At this time, the two spur gears 8022 rotate relative to each other. At the same time, the chain transmission mechanism 8026 can drive the rotating rod 501 to rotate, that is, link the auger blade 801 with the rotating rod 501.

[0046] As shown in Figure 7, the present invention discloses a further technical solution for optimizing the material dispersing effect of the bridge breaking device 5. A stirring blade 9 is rotatably installed inside the second feeding hopper 4, located on one side of the rotating rod 501. A second motor 10 is installed on the outside of the second feeding hopper 4 to drive the stirring blade 9 to rotate. When the rotating rod 501 rotates, the stirring rod 502 can push the material toward the stirring blade 9. The stirring blade 9 can disperse the material while rotating, thereby improving the material dispersing effect of the bridge breaking device 5.

[0047] As shown in Figures 1 and 2, the specific structure of the material gate assembly 3 of this utility model is disclosed. The material gate assembly 3 includes a guide plate 301 arranged in an inverted V-shape in the feeding channel 2. A baffle 302 is hinged in the feeding channel 2. The hinge axis of the baffle 302 is located below one of the guide plates 301. The hinge axis of the baffle 302 passes through the feeding channel 2 and is connected to a connecting block 303. The connecting block 303 is L-shaped. A brake cylinder 304 is hinged to the outside of the feeding channel 2. Its output end is connected to the connecting block 303. The hinge axis of the baffle 302 and the brake cylinder 304 are respectively connected to the two ends of the connecting block 303. When the brake cylinder 304 extends or retracts, it can drive the baffle 302 to rotate along the hinge axis through the connecting block 303. When the baffle 302 abuts against the guide plate 301, the feeding channel 2 can be closed. When the baffle 302 separates from the guide plate 301, the feeding channel 2 can be opened.

[0048] As shown in Figure 2, the present invention discloses a further technical solution for the movement of the baffle 302. An angle sensor 11 is installed on the connecting block 303. The angle sensor 11 is oriented in the same direction as the baffle 302. The angle sensor 11 is electrically connected to the existing PLC controller and can feed back the specific angle of the baffle 302 to the PLC controller for control feedback. That is, the extension and retraction of the brake cylinder 304 is controlled by the feedback signal, thereby controlling the opening of the baffle 302, thereby controlling the material discharge speed. The opening of the material gate can be adjusted for different materials so that the material is less likely to bridge in the first discharge hopper 1 and the second discharge hopper 4.

[0049] As shown in Figure 2, the present invention discloses a further technical solution for the movement of the baffle 302. A rotary paddle level sensor 12 is installed on the feeding channel 2. The rotary paddle level sensor 12 is electrically connected to the existing PLC controller, and its movable end rotates through the feeding channel 2. When the material is below the position of the rotary paddle level sensor 12, its movable end rotates without resistance, so it will not send a material arrival signal. When the material is above the position of the rotary paddle level sensor 12, its movable end rotates and contacts the material, and will be subject to a certain frictional resistance, thus sending a material arrival signal. The feedback signal controls the extension and retraction of the brake cylinder 304 to close the feeding channel 2, thereby reducing the occurrence of material bridging due to excessive material entering.

[0050] The above embodiments are merely descriptions for clearly illustrating the present utility model, and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all implementations here, and the obvious variations or modifications derived therefrom are still within the protection scope of the present utility model.
