Abstract
Description
Technical Field
[0001] This utility model belongs to the field of pet food technology, specifically relating to a semi-dry pet food extruder. Background Technology
[0002] A semi-dry pet food extruder is a piece of equipment specifically designed for producing semi-dry pet food. Its core feature is that it uses physical extrusion molding technology to process raw materials into granular products (such as meat strips or meat granules) through the extrusion action of a screw or gear, and controls the moisture content of the product to keep it in a semi-dry state (between dry and moist). This equipment usually combines processes such as pressurization, heating or cooling to meet the production requirements of semi-dry food.
[0003] Due to factors such as production scale and cost control, some companies choose to install intelligent conveying systems for receiving materials in their existing semi-dry pet food extruders, while others choose to manually change trays and material frames. However, when manually changing trays or material frames, there will inevitably be operational downtime, but the discharge port is still continuously discharging materials, causing food pellets to fall to the ground and adhere to dirt. The amount of waste caused in the long run is not negligible, leading to increased costs. Utility Model Content
[0004] The purpose of this invention is to provide a semi-dry pet food extruder. Through a guide switching mechanism, one top plate can be manually controlled to rise while the other descends, thereby switching the tilt direction of the guide plate. This allows the granules at the discharge port to fall onto the material frames that alternately fall onto both sides, saving the time of stopping to empty the material box, improving the continuity of unloading, avoiding the waste of granules caused by changing material frames, and having a simple structure and low cost.
[0005] The specific technical solution adopted by this utility model is as follows:
[0006] A semi-dry pet food extruder includes a discharge port installed at the discharge end of the extruder. A guide plate is rotatably provided below the discharge port. A rotating rod is rotatably connected to the extruder at a position below the guide plate. A linkage frame is fixedly connected to the outer wall of the rotating rod. Extension rods are symmetrically embedded in the linkage frame through a sliding groove in the middle. One end of the extension rod is fixedly connected to a top plate, and its top is in contact with the guide plate.
[0007] The guide plate is rotatably connected to the extruder via a rotating shaft, and the other end of the extension rod is slidably connected to the extruder.
[0008] The extruder end is also provided with a guide switching mechanism, including:
[0009] A fixing frame fixed to the outside of the discharge port;
[0010] The U-shaped plate fixed to the bottom of the frame has guide grooves on both sides.
[0011] The guide switching mechanism further includes a sliding arm that is slidably fitted in the guide groove. One end of the sliding arm is fixedly connected to the top plate, and the other end has a through groove.
[0012] The guide switching mechanism further includes: a horizontal plate fixed between the two arms of the U-shaped plate, with a sliding plate slidably fitted on one side of the plate. The sliding plate is used to embed into the through slot, and an operating handle is fixedly connected to the top of the sliding plate.
[0013] The U-shaped plate is fixedly connected to the extruder via a fixing rod at its bottom.
[0014] The technical advantages achieved by this utility model are as follows: the guide switching mechanism allows manual control of one top plate to rise while the other descends, thereby switching the tilt direction of the guide plate, so that the granules at the discharge port can fall into the material frames that alternately fall to both sides, saving the time of stopping to empty the material box, improving the continuity of unloading, avoiding the waste of granules caused by replacing the material frames, and the structure is simple and the cost is low.

[0021] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0022] like Figures 1-4 As shown, a semi-dry pet food extruder includes a discharge port 101 installed at the discharge end of the extruder 1. The end of the extruder 1 is also provided with a guide switching mechanism, including: a fixed frame 102 fixed to the outside of the discharge port 101; a U-shaped plate 104 fixed to the bottom of the fixed frame 102, with guide grooves 105 on both sides of the plate; a sliding arm 106 slidably fitted in the guide groove 105, one end of the sliding arm 106 being fixedly connected to a top plate 108, and the other end having a through groove 107; a horizontal plate 112 fixed between the two arms of the U-shaped plate 104, with a sliding plate 113 slidably fitted on one side of the plate, the sliding plate 113 being used to embed into the through groove 107; an operating handle 114 fixedly connected to the top of the sliding plate 113; and the U-shaped plate 104 being fixedly connected to the extruder 1 via a fixed rod 115 at its bottom.
[0023] According to the above structure, receiving boxes are respectively arranged at the end of the extruder 1 and below both sides of the discharge port 101. The guide plate 103 is initially in an inclined state, with its high end attached to one side of the bottom of the discharge port 101. The extruded semi-dry granular material falls from the discharge port 101 onto the inclined slope of the guide plate 103 and slides into the receiving box on one side. When the receiving box is close to full load, the guiding direction is switched by the following linkage mechanism: First, the operating handle 114 is pushed laterally, driving the sliding plate 113 to move along the horizontal plate 112 and disengage from the slot 107 of the sliding arm 106. Then, according to the working conditions, any sliding arm 106 on the U-shaped plate 104 is selected for vertical displacement operation: if the high sliding arm 106 is selected, a downward action is performed; if the low sliding arm 106 is selected, an upward action is performed. Taking the upward push of the low-position sliding arm 106 as an example, this action drives the extension rod 109 to rise vertically along the side wall of the extruder 1 through the top plate 108, and the fixed frame 102 and the fixed rod 115 provide stable support for the U-shaped plate 104.
[0024] See attached document Figures 1-4 A guide plate 103 is rotatably provided below the discharge port 101. The guide plate 103 is rotatably connected to the extruder 1 via a rotating shaft. A rotating rod 111 is rotatably connected to the extruder 1 below the guide plate 103. A linkage frame 110 is fixedly connected to the outer wall of the rotating rod 111. An extension rod 109 is symmetrically embedded in the linkage frame 110 through a sliding groove in the middle. One end of the extension rod 109 is fixedly connected to the top plate 108, and its top is in contact with the guide plate 103. The other end of the extension rod 109 is slidably connected to the extruder 1.
[0025] According to the above structure, during the upward movement of the top plate 108, the original low end of the guide plate 103 is lifted up, making it seal and fit against the other side of the discharge port 101, thereby changing the direction of material sliding to another empty receiving box. When the single-sided extension rod 109 rises, the linkage frame 110 is driven to rotate around the axis by the rotating rod 111, causing the extension rod 109, top plate 108 and sliding arm 106 on the opposite side to descend synchronously. The long sliding groove in the middle of the linkage frame 110 provides axial displacement compensation space for the extension rod 109, effectively avoiding motion interference. After the guide switching is completed, the sliding plate 113 is pushed again to embed into the groove 107 of the currently low-positioned sliding arm 106, realizing the position locking of the bidirectional top plate 108, ensuring that both ends of the guide plate 103 are reliably supported. Preferably, the surface of the guide plate 103 can be coated with a food-grade non-stick coating (such as a polytetrafluoroethylene coating) to reduce the risk of material adhesion and improve the smoothness of material guidance.
[0026] The working principle of this utility model is as follows: receiving boxes are respectively configured at the end of the extruder 1 and below both sides of the discharge port 101. The guide plate 103 is initially in an inclined state, with its high end attached to one side of the bottom of the discharge port 101. The semi-dry granular material extruded and formed falls through the discharge port 101 onto the inclined slope of the guide plate 103 and slides into the receiving box on one side.
[0027] Furthermore, when the receiving box is nearly full, the material guiding direction is switched via the following linkage mechanism: First, the operating handle 114 is pushed laterally, driving the sliding plate 113 to move along the horizontal plate 112 and disengage from the slot 107 of the sliding arm 106. Then, according to the working conditions, any sliding arm 106 on the U-shaped plate 104 is selected for vertical displacement: if the high sliding arm 106 is selected, a pull-down action is performed; if the low sliding arm 106 is selected, an upward push action is performed.
[0028] Furthermore, taking the upward push of the low-position sliding arm 106 as an example, this action drives the extension rod 109 to rise vertically along the side wall of the extruder 1 through the top plate 108. The fixed frame 102 and the fixed rod 115 provide stable support for the U-shaped plate 104. During the upward movement of the top plate 108, the original low end of the guide plate 103 is lifted up, so that it is sealed and fitted with the other side of the discharge port 101, thereby changing the direction of material sliding to another empty receiving box.
[0029] Furthermore, when the single-sided extension rod 109 rises, the linkage frame 110 is driven to rotate around the axis by the rotating rod 111, causing the extension rod 109, the top plate 108 and the sliding arm 106 on the opposite side to descend synchronously. The long slide groove in the middle of the linkage frame 110 provides axial displacement compensation space for the extension rod 109, effectively avoiding motion interference.
[0030] Furthermore, after the guide switching is completed, the sliding plate 113 is pushed again to embed into the groove 107 of the sliding arm 106 which is currently in the lower position, thereby locking the position of the bidirectional top plate 108 and ensuring that both ends of the guide plate 103 are reliably supported. Preferably, the surface of the guide plate 103 can be coated with a food-grade non-stick coating (such as a polytetrafluoroethylene coating) to reduce the risk of material adhesion and improve the smoothness of material guidance.
[0031] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
