[0001] The invention relates to the field of animal fat byproduct processing, and in particular to an animal fat byproduct smelting device. Background Art

[0002] As is known, the smelting of animal fat byproducts includes the following steps: 1. crushing the fat; 2. boiling the oil; 3. separating the oil residue; 4. pressing the oil residue. In the process of pressing the oil residue, a screw oil press is usually used for pressing. The animal oil will flow out from the gap of the pressing cage and be collected uniformly.

[0031] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0032] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "degree", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "radial" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0033] Reference Figure 1-9 An embodiment of the present invention provides an animal fat by-product smelting device, comprising a first cylinder 1 and a second cylinder 2 sleeved on the outside of the first cylinder 1, wherein an annular gap 3 is provided between the first cylinder 1 and the second cylinder 2 for a ring formed after the fat is squeezed to pass through, and further comprising a first cutting assembly and a second cutting assembly; the first cutting assembly is used for cutting the ring in the axial direction, and the second cutting assembly is used for cutting the ring in the circumferential direction.

[0034] Specifically, the screw oil press includes a feed hopper, a screw conveying mechanism, a pressing chamber and other structures. The first cylinder 1 and the second cylinder 2 are arranged at the end of the screw conveying mechanism. When pressing oil, animal oil residue (hereinafter referred to as oil residue) is added into the pressing chamber through the feed hopper, and then the screw conveying mechanism is controlled to rotate by a driving motor and other power components to convey the oil residue into the pressing chamber. Then, under the action of the screw conveying mechanism, the oil residue is continuously squeezed to squeeze out the residual oil in the oil residue to achieve the effect of solid-liquid separation. The squeezed oil residue product is squeezed out through the annular gap 3 between the first cylinder 1 and the second cylinder 2 to form a cake ring, and then the cake rod is driven to rotate by the screw conveying mechanism to break the formed cake ring into blocks. This is a prior art and will not be repeated. The core innovation point of the embodiment of the present invention One is that by setting a first cutting component and a second cutting component, the first cutting component can be a horizontally arranged cutter, and the second cutting component can be a rotatably arranged cutter, and both are arranged on the movement stroke of the ring, so that the first cutting component cuts the ring in the axial direction, and the second cutting component cuts the ring in the circumferential direction, and there are multiple first cutting components and second cutting components. The effect of such a setting is that when the ring is extruded from the annular gap 3, multiple first cutting components cut the ring into multiple long strips, and then the second cutting component cuts it evenly into multiple sections. In this way, through the cooperation of the first cutting component and the second cutting component, the ring can be cut into multiple uniform block structures, thereby reducing the space occupied by the tile cake and facilitating the subsequent processing of animal feed.

[0035] Preferably, the first cutting assembly includes a plurality of first cutters 4, and the plurality of first cutters 4 are arranged in an array on the inner circumferential surface of the second cylinder 2. Specifically, the cutting edges of the plurality of first cutters 4 face the left side, which is also the direction of movement of the doughnut ring. The effect of such arrangement is that when the doughnut ring is extruded from the annular gap 3, it will contact the cutting edge of the first cutter 4 and be passively cut into a plurality of strip-shaped doughnut strips by the plurality of first cutters 4.

[0036] Preferably, the second cutting assembly includes a spiral shaft 5 and a second cutter 6 disposed on the spiral shaft 5, and the second cutter 6 is fixedly connected to the outer circumferential surface of the spiral shaft 5. Specifically, one end of the spiral shaft 5 close to the first cylinder 1 is adapted to the radial dimension of the inside of the first cylinder 1 to prevent oil residue from entering the gap between the two, and the spiral shaft 5 passes through the space inside the first cylinder 1 and extends to the outside, and the second cutter 6 is fixedly connected to the outer circumferential surface of the end, and the second cutters 6 are preferably four, and the four second cutters 6 are arranged in an array on the outer circumferential surface of the spiral shaft 5, the right ends of the first cylinder 1 and the second cylinder 2 are located at the same position, and the first cutter 4 is simultaneously attached to the first cylinder 1 and the second cylinder 2, and the effect of such a setting is that when the cake strip is extruded from the annular gap 3, the spiral shaft 5 is in a rotating state during this process, which will drive multiple second cutters 6 to rotate synchronously, so that multiple second cutters 6 can simultaneously passively cut multiple cake strips, so that the cake strips are evenly divided into multiple parts to obtain multiple tile cakes that are approximately parallelograms.

[0037] It should be noted that when tile cakes of different sizes are required, this can be achieved by increasing or decreasing the number of first cutters 4 and second cutters 6. That is, when the rotation speed of the spiral shaft 5 remains unchanged, when a smaller tile cake is required, it is only necessary to increase the number of first cutters 4 and second cutters 6. When a larger tile cake is required, it is only necessary to reduce the number of first cutters 4 and second cutters 6.

[0038] As another embodiment of the present invention, two cutting edges are symmetrically arranged on the second cutter 6; the spiral shaft 5 includes a first section 501 and a second section 502, and a first transmission component for making the second section 502 and the first section 501 rotate in the same direction and a second transmission component for making the second section 502 and the first section 501 rotate in the opposite direction are provided between the first section 501 and the second section 502. Specifically, the spiral blades on the surface of the spiral shaft 5 are arranged on the first section 501, that is, when the second section 502 rotates in the opposite direction, it will not affect the pressing direction of the screw press. The first transmission component can be a simple plug-in method to drive the second section 502 to rotate in the same direction as the first section 501, and the second transmission component can be a gear matching method to drive the second section 502 to rotate in the opposite direction. The purpose of such a setting is that when the screw press is running, it preferentially transmits its kinetic energy to the second section 502 through the first transmission component, so that the cutting edge on one side of the second cutter 6 passively cuts the cake strips. When the cutting edge on this side is damaged due to long-term use, the first transmission component is switched to the second transmission component. In this way, the second section 502 and the second cutter 6 on its outer peripheral surface can be driven to rotate in the opposite direction through the second transmission component, so that the cutting edge on the other side of the second cutter 6 cuts the cake strips, thereby increasing the service life of the second cutter 6.

[0039] Preferably, the first transmission assembly includes a first transmission rod 7, and the first section 501 and the second section 502 are respectively provided with a first transmission groove 8 and a second transmission groove 9, and both ends of the first transmission rod 7 are respectively plugged into the first transmission groove 8 and the second transmission groove 9. Specifically, a limiting structure is provided between the first transmission rod 7 and the second transmission groove 9 for preventing the two from rotating relative to each other. A plurality of first elastic limiting strips 10 (that is, they can be extended and retracted in the direction of their length) are provided on the outer peripheral surface of one end of the first transmission rod 7 close to the first section 501. The inner side wall of the first transmission groove 8 is provided with a plurality of first limiting grooves 11 adapted to the first elastic limiting strips 10. The inner side wall of the first transmission groove 8 is provided with an annular groove 12 connected to the plurality of first limiting grooves 11, and the axial length of the annular groove 12 is adapted to the length of the elastic limiting strip. The effect of such a setting is that when the first transmission member acts, the first elastic limiting strip 10 on the first transmission rod 7 is plugged into the first limiting groove 11, and the power on the first section 501 will be transmitted to the second section 502 via the first transmission rod 7, thereby driving the second cutter 6 to rotate to cut the cake strips. When the first transmission component is not in effect, the first transmission rod 7 is controlled to slide toward the direction of the first section 501, so that the first elastic limiting strip 10 is disengaged from the first limiting groove 11. The first section 501 and the first transmission rod 7 lose their limiting function, so the power of the first section 501 cannot be transmitted to the first transmission rod 7 and the second section 502. In this process, the first transmission rod 7 always rotates synchronously with the second section 502 under the action of the limiting structure. When the first transmission assembly works again, the first transmission rod 7 is controlled to move in the opposite direction. During this period, two situations may occur. First, the first elastic limiting strip 10 is just in contact with the second section 501. First, the limiting groove 11 is plugged in to realize the transfer of kinetic energy. Secondly, the first elastic limiting strip 10 cannot be plugged in with the first limiting groove 11 in the initial state. At this time, the first elastic limiting strip 10 will shrink itself under the action of the squeezing of the side wall of the rotating shaft to achieve avoidance. Since the first section 501 continues to rotate at this time, when the first elastic limiting strip 10 coincides with the first limiting groove 11, the elastic force of the first elastic limiting strip 10 is released, so that the first elastic limiting strip 10 is plugged in with the first limiting groove 11 to realize the transfer of kinetic energy.

[0040] Preferably, the second transmission assembly includes a transmission gear 13 and a direction-changing gear 14 meshing with the transmission gear 13, the transmission gear 13 is arranged on the first section 501, the direction-changing gear 14 is rotatably arranged inside the first cylinder 1, a second transmission rod 15 is slidably arranged on the direction-changing gear 14, a first synchronous wheel 16 is arranged on the second transmission rod 15, a second synchronous wheel 17 is arranged on the first transmission rod 7, and a synchronous belt 18 is arranged between the first synchronous wheel 16 and the second synchronous wheel 17. Specifically, the transmission gear 13 is fixedly connected to the outer circumference of the first section 501, the direction-changing gear 14 is arranged on the inner end surface of the first cylinder 1 through the rotating shaft, a third transmission groove 19 is provided on the rotating shaft, one end of the second transmission rod 15 is fixedly connected to the first synchronous wheel 16, and the other end is plugged into the third transmission groove 19, a plurality of second elastic limiting strips 20 are arranged on the outer circumference of the second transmission rod 15, a plurality of second limiting grooves 21 adapted to the second elastic limiting strips 20 are arranged on the inner side wall of the third transmission groove 19, the second synchronous wheel 17 is fixedly connected to the outer circumference of the first transmission rod 7, and the first synchronous wheel 16 is connected to the second synchronous wheel 16. The wheel 17 is connected by a synchronous belt 18. The purpose of such a setting is that when the second transmission member acts, when the second elastic limiting strip 20 on the second transmission rod 15 is plugged into the second limiting groove 21, the transmission gear 13 on the first section 501 will transfer its kinetic energy to the direction-changing gear 14, and transfer it to the first synchronous wheel 16 through the second transmission rod 15, and transfer it to the second synchronous wheel 17 through the synchronous belt 18, thereby driving the first transmission rod 7 (and the first elastic limiting strip 10 is located in the annular groove 12 at this time) and the second cutter 6 to rotate to cut the cake strips. When the second transmission component is not in effect, the second transmission component is controlled to rotate. The transmission rod 15 slides in the direction away from the direction-changing gear 14, so that the second elastic limiting strip 20 is disengaged from the second limiting groove 21, and the first elastic limiting strip 10 is completely located outside the third transmission groove 19. At this time, the direction-changing gear 14 and the second transmission rod 15 lose their limiting effect. Therefore, the power of the first section 501 cannot be transmitted to the second transmission rod 15 through the transmission gear 13 and the direction-changing gear 14. In this process, the first transmission rod 7 always rotates synchronously with the second section 502 under the action of the limiting structure. When the second transmission assembly works again, the second transmission rod 15 is controlled to move in the opposite direction. During this period, two situations may occur. First, the second elastic limit strip 20 is just plugged into the second limit groove 21 to realize the transfer of kinetic energy. Second, the second elastic limit strip 20 cannot be plugged into the second limit groove 21 in the initial state. At this time, the second elastic limit strip 20 will shrink to achieve avoidance. Since the first section 501 continues to rotate at this time, it will drive the changing gear 14 and the rotating shaft to rotate. Therefore, when the second elastic limit strip 20 coincides with the second limit groove 21, the elastic force of the second elastic limit strip 20 is released, so that the second elastic limit strip 20 is plugged into the second limit groove 21 to realize the transfer of kinetic energy.

[0041] Furthermore, it also includes a switching component, which includes a transmission plate 23, which is rotatably connected to the first transmission rod 7 and the second transmission rod 15 at the same time, and also includes a power component for driving the transmission plate 23 to move. Specifically, the transmission plate 23 is provided with two circular holes respectively adapted to the first transmission rod 7 and the second transmission rod 15, and a convex ring or other limiting structure is provided between the first transmission rod 7 and the circular hole to prevent the two from axially relative movement, and a convex ring or other limiting structure is also provided between the second transmission rod 15 and the circular hole to prevent the two from axially relative movement. The electric push rod 22 is fixedly connected to the inner end surface of the first cylinder 1, and the power component can be an existing reciprocating drive component such as the electric push rod 22 and an electromagnet. The effect of such a setting is that when the first transmission component is working and the second transmission component is not working, the first elastic limiting strip 10 is plugged into the first limiting groove 11, and the second elastic limiting strip 20 is located outside the third transmission groove 19. When the cutting edge on one side of the second cutter 6 is damaged, it is necessary to switch to the second transmission component. When driving the second cutter 6 to reverse, the transmission plate 23 is driven to move in the direction of the first section 501 by the electric push rod 22. Under the action of the limiting structure, the first transmission rod 7 and the second transmission rod 15 are driven to move synchronously in the direction of the first section 501, thereby driving the first elastic limiting strip 10 to be inserted into the annular groove 12 to release the transmission effect of the first transmission component. At the same time, the second elastic limiting strip 20 is synchronously driven by 18 to be inserted into the second limiting groove 21, so that the second transmission component starts to work. When the second transmission component completes the operation, the transmission plate 23 is controlled to move in the opposite direction by the electric push rod 22. At this time, the transmission effect of the second transmission component is released. At the same time, the first transmission component starts to work, thereby realizing the synchronous switching of the working states of the first transmission component and the second transmission component.

[0042] It should be noted that, since the second cutter 6 has a width, when the cutting blade of the second cutter 6 has finished cutting the cake strip, since the cake strip is in a state of continuous movement, the cut cake strip will abut against the side of the second cutter 6, which will increase the lateral force on the second cutter 6, which will reduce the service life of the second cutter 6, and on the other hand, will cause the cake strip to be broken into an uneven shape. As another embodiment of the present invention, the second cutter 6 is arranged obliquely on the outer peripheral surface of the spiral shaft 5. Specifically, the oblique arrangement means that only one edge of the second cutter 6 is in contact with the first cylinder 1 and the second cylinder 2, so that the surface contact of the second cutter 6 can be converted into line contact. At this time, there is a certain avoidance space between the rear of the movement stroke of the second cutter 6 and the second cutter 6, so that the cake strip coming out of the annular groove 12 later will not contact the side of the second cutter 6, thereby improving the service life of the second cutter 6 and making the shape of the cut tile cake uniform, so as to facilitate the storage of the tile cake.

[0043] Furthermore, a driving gear 24 is disposed on the second cutter 6 , and a toothed plate 25 is disposed on the first transmission rod 7 , and the driving gear 24 meshes with the toothed plate 25 . Specifically, a mounting groove is provided inside the second section 502, a cylindrical rod is provided at the bottom of the second cutter 6, and the cylindrical rod passes through the side wall of the second section 502 and passes through the mounting groove, the driving gear 24 is fixedly connected to one end of the cylindrical rod close to the central axis of the second section 502, the tooth plate 25 is L-shaped, one end of which is fixedly connected to the outer peripheral surface of the first transmission rod 7, and the other end is provided with a tooth portion, which is meshed with the driving gear 24. The purpose of such a setting is that when the electric push rod 22 drives the first transmission assembly and the second transmission assembly to switch, it will drive the first transmission rod 7 to move back and forth, thereby driving the tooth plate 25 to move back and forth. Since the tooth plate 25 is meshed with the driving gear 24, it will drive the driving gear 24 and the second cutter 6 to rotate. In this way, while changing the second cutter 6 to rotate around the central axis of the second section 502, the second cutter 6 itself is driven to rotate passively. At this time, the other cutting edge of the second cutter 6 is in contact with the first cylinder 1 and the second cylinder 2 to achieve the cutting of the cake strips.

[0044] As another embodiment of the present invention, the second cutter 6 includes a first part 601 and a second part 602 which are slidably connected to each other, the first part 601 is provided with a cutting edge, the first cylinder 1 is provided with a wave groove 26, and the second part 602 is provided with a limit rod 27, and the limit rod 27 passes through the first part 601 and is slidably connected with the wave groove 26. Specifically, in this embodiment, the second part 602 is fixedly connected to the outer peripheral surface of the second section 502, and the second part 602 is provided with a slide groove, and the first part 601 is slidably connected with the slide groove, so that the first part 601 can slide along the radial direction of the second section 502, and the wave groove 26 is arranged with a plurality of highest points and a plurality of lowest points along the radial direction of the second section 502, the limit rod 27 is provided with a cylindrical section and a threaded section, the first part 601 is provided with a bracket 28, and the bracket 28 is provided with a slide hole 29, and the slide hole 29 is slidably arranged inside. There is a sliding seat 30, the threaded section on the limiting rod 27 is threadedly connected to the sliding seat 30, a waist-shaped through hole 31 is opened on the second part 602, and the cylindrical section of the limiting rod 27 passes through the through hole 31 and is slidably connected to the wave groove 26. The length of the through hole 31 is greater than the radial dimension of the cylindrical section to provide a certain activity space for the cylindrical section. The length of the cutting edge of the second cutter 6 is greater than the distance between the highest point and the lowest point of the wave groove 26. That is, when the first part 601 slides radially along the spiral shaft 5, the cutting edge of the second cutter 6 always covers the annular gap 3. The function is that when the first part 601 is installed, the through hole 31 is arranged corresponding to the wave groove 26, and then the sliding seat 30 is slid to the corresponding position, the cylindrical section is inserted into the wave groove 26, and then the limiting rod 27 is rotated. Under the action of the threaded connection between the limiting rod 27 and the sliding seat 30, the limiting rod 27 will be further inserted into the wave groove 26, and the position of the limiting rod 27 is fixed by the threaded connection. In this way, the installation of the first part 601 is completed. When the second section 502 drives the second cutter 6 to rotate, the cylindrical section will be moved along the wave groove 26. 6, and under the structural characteristics of the wave groove 26, the second cutter 6 will be driven to rotate around the central axis of the spiral shaft 5 while sliding back and forth in the radial direction of the spiral shaft 5, thereby producing a sawing effect on the cake strips, thereby improving the cutting effect of the second cutter 6; and, when the cutting edge on the first part 601 is damaged, the limit rod 27 is rotated in the reverse direction to pull the limit rod 27 out of the through hole 31, and then the first part 601 is pulled out of the slide groove, so that only the first part 601 needs to be replaced, which is not only convenient to operate but also reduces the replacement cost.

[0045] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
