Description

Technical Field

[0001] This utility model relates to an extruder, and more particularly to a bottom-discharge horizontal extruder, belonging to the technical field of extrusion equipment. Background Technology

[0002] An extruder is a processing equipment used in the food, feed, and chemical industries, and is widely used in the production of extruded foods, pet food, and aquatic feed. The extruder has a high-pressure extrusion cylinder. Material enters the cylinder and, under the extrusion of the screw, mechanical energy is converted into heat energy, gradually maturing the material. When extruded from the die at the discharge end, the material rapidly expands in volume. The discharge die has multiple densely packed holes, and a cutter is located on the outside of the die to cut the extruded material into porous, soft, extruded pellets. When the material type or particle size needs to be changed, die changing operations are required; therefore, the discharge end of the extruder is usually designed to be openable.

[0003] During production, a cutting chamber needs to be installed at the puffing discharge cavity, and the cutter adjusted to fit against the outer wall of the discharge mold. Discharge can be either bottom discharge or top suction discharge. After production, the cutting chamber needs to be removed to clean and maintain any residual material in the discharge cavity and mold. When changing product types, when the screw wears out, or when the machine becomes clogged, it may be necessary to disassemble the puffing cavity and screw.

[0004] Chinese utility model patent CN 215886102U discloses a sliding rail anti-lifting device, including a support frame comprising several support columns and support beams. At least one heavy-duty guide rail is fixed on the support frame, and a lifting assembly is movable on the heavy-duty guide rail. Symmetrical inclined guide surfaces are provided on both sides of the heavy-duty guide rail. The lifting assembly includes at least one pair of movable bodies for moving on the inclined guide surfaces, with each pair of movable bodies corresponding one-to-one with the inclined guide surfaces on both sides of the heavy-duty guide rail. This technical solution has the following problems: 1. The gantry-type support frame occupies a large area, requiring a certain amount of space to be reserved in front of the extruder. It can only move radially along the extrusion cavity, affecting the space for disassembling, inspecting, and maintaining the extruder screw; 2. When installing the discharge mechanism, it needs to be aligned with the coaxial axis of the extrusion cavity, which is time-consuming and labor-intensive. Utility Model Content

[0005] The purpose of this invention is to overcome the problems existing in the prior art and provide a bottom-discharge horizontal extruder that can flexibly rotate the discharge mechanism and achieve rapid and accurate positioning of the discharge mechanism, thereby reducing the processing difficulty.

[0006] To solve the above technical problems, this utility model provides a bottom-discharge horizontal extruder, including a discharge mechanism hinged to the discharge end of the extruder. The discharge mechanism includes a cutting chamber, in which a cutter is provided to cut the extruded material into granules. The bottom of the cutting chamber is provided with a discharge port. A fixed column is provided on one side of the discharge end of the extruder. A rotatable U-shaped rocker arm is hinged to the upper end of the fixed column. The free end of the U-shaped rocker arm is bent downward and fixedly connected to a top plate. The four corners of the top plate are respectively connected to a middle plate through upper and lower adjusting studs. The middle plate is provided with multiple waist-shaped grooves extending in the left and right direction. Each bolt passes through the waist-shaped groove and its lower end is connected to a U-shaped support plate. The front and rear sides of the U-shaped support plate are bent downward to form the vertical walls of the U-shaped support plate. The left and right sides of the two vertical walls of the U-shaped support plate are respectively connected by guide columns. Slide seats are respectively fitted on the two guide columns near the front and rear ends. The discharge mechanism is fixedly connected below each slide seat.

[0007] As an improvement of this utility model, the left and right sides of the U-shaped support plate are respectively welded with upwardly extending left and right adjustment ears, and each left and right adjustment ear is respectively screwed with a horizontal adjustment rod, and the free end of each horizontal adjustment rod abuts against the left and right sides of the middle plate.

[0008] As a further improvement of this utility model, a stop block is clamped on the guide post to limit the extreme position of the slide.

[0009] As a further improvement of this utility model, a transverse connecting arm is welded to the middle section of the fixed column, and the outer end of the transverse connecting arm is connected to the base of the extruder.

[0010] As a further improvement of this utility model, the cutting chamber is provided with positioning support rods and tensioning handles at the four corners facing the extruder. When the cutting chamber is in the closed state, the free ends of each positioning support rod are inserted into the positioning holes at the discharge end of the extruder, and the tensioning handles are respectively connected to the pull rings at the discharge end of the extruder.

[0011] As a further improvement of this utility model, each positioning support rod has a positioning step at its end and a guide head at its end.

[0012] As a further improvement of this utility model, diagonal tie rods are welded to the two inner corners of the U-shaped rocker arm.

[0013] Compared with the prior art, the present invention has achieved the following beneficial effects: 1. The rocker arm structure allows the cutting chamber to rotate and move away, without occupying the front space, saving equipment space and making it more adaptable to complex on-site installation environments.

[0014] 2. The structure is simple, with less welding on the main body. It adopts a U-shaped rocker arm formed by one-piece steel pipe, which reduces the production cost for manufacturers and the procurement cost for customers. In addition, the simple and easy-to-understand structure reduces the learning cost of extrusion operation.

[0015] 3. The cutting chamber can be moved back and forth for precise positioning. When opening, it first moves backward to disengage from its positioning position, and then rotates, making operation and cleaning more convenient. The cutting chamber can also be adjusted in height and left and right directions to ensure precise positioning.

[0016] 4. The fixed column is connected to the base of the extruder, and the inner corner of the U-shaped rocker arm is equipped with a diagonal tie rod to make the structure and support more stable. Attached Figure Description

[0037] like Figures 1 to 8 As shown, the extruder 1 of this utility model includes a high-pressure extrusion cylinder, in which a screw is provided. The screw drive is located at the feeding end, and the discharge mechanism is hinged to the discharge end of the extruder. The discharge mechanism includes a cutting chamber 2, in which a cutter 4 is provided to cut the extruded material into granules. The cutter 4 is coaxially driven by a cutter motor 3, and a discharge port 2a is provided at the bottom of the cutting chamber 2.

[0038] A fixed column 5 is provided on one side of the extruder discharge end. The lower end of the fixed column 5 is supported on the ground by foot. A transverse connecting arm 5a is welded to the middle section of the fixed column 5. The outer end of the transverse connecting arm 5a is connected to the extruder base to improve the stability of the support and prevent shaking.

[0039] A rotatable U-shaped rocker arm 6 is hinged to the upper end of the fixed column 5. The fixed end of the U-shaped rocker arm 6 is supported in the fixed column 5 by bearings. A rotation damping mechanism 5b is provided on the outer wall of the upper end of the fixed column 5 to dampen the rotation of the U-shaped rocker arm 6 and improve the safety of operation. Diagonal tie rods 6a are welded to the two inner corners of the U-shaped rocker arm 6 to improve strength and stability.

[0040] The free end of the U-shaped rocker arm 6 is bent downwards and fixedly connected to a top plate 7. The four corners of the top plate 7 are connected to a middle plate 8 via upper and lower adjusting studs 7a, allowing adjustment of the height of the middle plate 8. The middle plate 8 has multiple waist-shaped grooves extending in the left-right direction. Bolts pass through these grooves and their lower ends are connected to a U-shaped support plate 9. Upward-extending left-right adjusting lugs are welded to the left and right sides of the U-shaped support plate 9. A horizontal adjusting rod 8a is screwed onto each left-right adjusting lug, with its free end resting against the left and right sides of the middle plate 8. The left-right position of the middle plate 8 can be adjusted using the horizontal adjusting rods 8a on both sides.

[0041] The front and rear sides of the U-shaped support plate 9 are bent downwards to form the vertical walls of the U-shaped support plate.
