Description

Technical Field

[0001] This invention relates to a conveying device, and more particularly to a fruit granule conveying device after fruit granule processing, belonging to the field of food processing technology. Background Technology

[0002] For conveying materials containing solid particles and with medium to high viscosity, such as fruit chunks in soup, the industry generally uses cam rotor pumps as the core conveying equipment. Compared with conventional conveyor models such as centrifugal pumps and single screw pumps, cam rotor pumps rely on a pair of synchronously meshing cam rotors to form a closed cavity to push the material, which can preserve the integrity of the fruit particles to the greatest extent. It is the mainstream choice for industrial conveying of fruit chunks in soup.

[0003] However, in actual industrial continuous production, fruit pieces tend to overlap, easily forming material arches at the variable diameter connection between the hopper and the feed inlet of the cam rotor pump. Furthermore, due to the equipment precision deviation in the fruit cutting process, the particle size of the fruit varies, and the equipment cannot simultaneously complete the screening and re-cutting of large fruit pieces during the conveying process, resulting in limited practical functions.

[0004] To address this issue, a fruit granule conveying device after fruit processing was designed. Summary of the Invention

[0019] To enable those skilled in the art to more clearly understand the technical solution of the present invention, the present invention will be further described in detail below with reference to embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0020] Example 1 like Figures 1-9 As shown, this embodiment provides a fruit granule conveying device after fruit granule processing, including a base 1, a cam rotor pump 2 for conveying fruit granules with soup and a drive motor 3 for providing power to the cam rotor pump 2 are fixed on the top of the base 1, the input end of the cam rotor pump 2 is connected to a transfer box 4, and the top of the transfer box 4 is connected to a hopper 5 for storing fruit granules to be conveyed. The transfer box 4 is vertically slidably equipped with a top rod 6 for breaking arches and clearing blockage. The top of the top rod 6 extends to the bottom discharge port of the hopper 5, and a cone block 7 is fixed to the top of the top rod 6. A reciprocating lifting mechanism 8 is provided on the base 1. The output end of the reciprocating lifting mechanism 8 is connected to the bottom end of the top rod 6 for transmission, which is used to drive the top rod 6 and the cone block 7 to reciprocate and lift, so as to realize synchronous arch breaking and unblocking during the conveying process. The hopper 5 is equipped with a conical filter screen 9 for screening fruit particles. An elastic support mechanism 10 is provided between the inner wall of the hopper 5 and the conical filter screen 9. The conical filter screen 9 is movably connected to the inner wall of the hopper 5 through the elastic support mechanism 10. The power output end of the reciprocating lifting mechanism 8 is connected to a shaking mechanism 11, which works in conjunction with the conical filter screen 9 to drive the conical filter screen 9 to shake and screen synchronously during the conveying process. A re-cutting mechanism 12 is provided between the conical filter screen 9 and the inner wall of the hopper 5, which is used to perform online synchronous shearing of the oversized fruit pieces intercepted by screening.

[0021] When the device is running, the drive motor 3 fixed on the top of the base 1 starts, and simultaneously provides power to the cam rotor pump 2 and the reciprocating lifting mechanism 8. The drive motor 3 drives the cam rotor pump 2 to run, so that the input end of the cam rotor pump 2 forms a negative pressure. The material with soup and fruit pieces in the hopper 5 enters the transfer box 4 through the discharge port at the bottom of the hopper 5, and then enters the input end of the cam rotor pump 2 from the transfer box 4, completing the continuous conveying of the soup and fruit pieces.

[0022] During the conveying process, the drive motor 3 synchronously drives the reciprocating lifting mechanism 8 to run. The reciprocating lifting mechanism 8 drives the top rod 6 to make continuous vertical reciprocating lifting motion along the inside of the transfer box 4, which in turn drives the cone block 7 at the top of the top rod 6 to reciprocate lifting synchronously. During the reciprocating lifting process, the cone block 7 continuously impacts and disperses the material at the bottom outlet of the hopper 5, destroying the arched bridge structure formed by the overlapping of the fruit pieces, and realizing the synchronous automatic arch breaking and unblocking of the feeding channel during the conveying process.

[0023] Simultaneously, the reciprocating lifting mechanism 8 drives the shaking mechanism 11 to operate synchronously via the top rod 6 and the cone block 7. The shaking mechanism 11, in conjunction with the elastic support mechanism 10, drives the conical filter screen 9 inside the hopper 5 to continuously reciprocate vertically. After the fruit chunks with soup to be conveyed are injected into the hopper 5, they first fall onto the top surface of the conical filter screen 9. With the continuous shaking of the conical filter screen 9, fruit chunks with a particle size that meets the conveying requirements of the cam rotor pump 2 fall through the sieve holes of the conical filter screen 9 to the bottom of the hopper 5, and then enter the transfer port through the discharge port. Box 4 completes the conveying process; oversized fruit pieces exceeding the conveying range of the cam rotor pump 2 are intercepted by the conical filter screen 9 and gather at the edge along the conical surface of the conical filter screen 9. Then, through the re-cutting mechanism 12 between the conical filter screen 9 and the inner wall of the hopper 5, the oversized fruit pieces are synchronously sheared online during the reciprocating shaking of the conical filter screen 9, processing the large fruit pieces to the particle size specifications that meet the conveying requirements. The qualified fruit pieces after shearing fall through the sieve holes of the conical filter screen 9 to the bottom of the hopper 5, completing the conveying process.

[0024] Example 2 The solution in Example 1 will be further described below with reference to its specific working method. In this embodiment, the reciprocating lifting mechanism 8 includes a rectangular frame plate 801, a vertical rod 802, a lever 803, a guide rod 804, and a transmission assembly; The rectangular frame plate 801 is horizontally fixed to the bottom end of the top rod 6; The vertical rod 802 is vertically fixed on both sides inside the transfer box 4, and the vertical rod 802 is vertically slidably connected to the rectangular frame plate 801; The lever 803 is rotatably mounted on the inner end face of the transfer box 4. One end of the lever 803 is vertically fixed with a guide rod 804, and the guide rod 804 extends to the inner side of the rectangular frame plate 801 and slides in cooperation with the inner wall of the rectangular frame plate 801. A transmission assembly is provided between the output end of the drive motor 3 and the lever 803 to synchronously drive the lever 803 to rotate, thereby providing power to the reciprocating lifting mechanism 8.

[0025] When the reciprocating lifting mechanism 8 is running, the transmission component transmits the power of the drive motor 3 to the lever 803, driving the lever 803 to rotate around the axis of the drive shaft 805. During the rotation of the lever 803, the guide rod 804, which is vertically fixed at its end, moves synchronously with the lever 803. At the same time, the guide rod 804 slides back and forth horizontally on the inner side of the rectangular frame plate 801, thereby driving the rectangular frame plate 801 to move in a vertical reciprocating linear motion along the vertical rod 802, which is vertically fixed at the bottom of the transfer box 4. During the reciprocating lifting of the rectangular frame plate 801, the top rod 6 and the cone block 7, which are fixed at the top, are driven to move synchronously, realizing the complete synchronization of the arch breaking and unblocking action and the conveying operation of the cam rotor pump 2.

[0026] In this embodiment, the transmission assembly includes a drive shaft 805, a driven pulley 806, a driving pulley 807, and a connecting belt 808; The drive shaft 805 is rotatably mounted on the side of the transfer box 4. One end of the drive shaft 805 extends into the interior of the transfer box 4 and is fixedly connected to the lever 803. A driven pulley 806 is fixed to the end of the drive shaft 805 away from the lever 803. The drive pulley 807 is fixed to the end of the output shaft of the drive motor 3, and the connecting belt 808 is sleeved between the drive pulley 807 and the driven pulley 806 to synchronously transmit the power of the drive motor 3 to the reciprocating lifting mechanism 8.

[0027] When the transmission assembly is running, the output shaft of the drive motor 3 drives the drive pulley 807 to rotate synchronously. The drive pulley 807 drives the driven pulley 806 to rotate synchronously through the connecting belt 808. In turn, the driven pulley 806 drives the drive shaft 805 to rotate around its own axis. Finally, the drive shaft 805 drives the lever 803 inside the transfer box 4 to rotate synchronously, thus completing the synchronous transmission of power.

[0028] In this embodiment, the elastic support mechanism 10 includes a fixing ring 1001, an outer sleeve 1002, a support rod 1003, and a return spring 1004; The fixing ring 1001 is fixed on the inner wall of the hopper 5, the outer sleeve 1002 is fixed in a ring array on the top of the fixing ring 1001, and the support rod 1003 is vertically slidably installed inside the outer sleeve 1002. The top of the support rod 1003 is fixedly connected to the bottom of the conical filter screen 9. The return spring 1004 is disposed inside the outer sleeve 1002. The bottom end of the return spring 1004 is fixedly connected to the inner bottom of the outer sleeve 1002, and the top end of the return spring 1004 is fixedly connected to the bottom end of the support rod 1003.

[0029] When the shaking mechanism 11 applies a driving force to the conical filter screen 9, the conical filter screen 9 drives the support rod 1003 to slide along the inner cavity of the outer sleeve 1002. At the same time, the support rod 1003 stretches or compresses the return spring 1004, causing the return spring 1004 to store elastic potential energy. When the driving force of the shaking mechanism 11 disappears, the return spring 1004 releases its elastic potential energy, controlling the support rod 1003 to slide back along the outer sleeve 1002, thereby driving the conical filter screen 9 to reset synchronously. Through the continuous deformation and reset of the return spring 1004, in conjunction with the driving force of the shaking mechanism 11, the continuous reciprocating shaking screening of the conical filter screen 9 is achieved.

[0030] In this embodiment, the shaking mechanism 11 includes a collar 1101, a mounting cylinder 1102, a ball bearing 1103, a compression spring 1104, a slide rod 1105, and an annular groove 1106; The collar 1101 is fixed to the top of the inner ring of the conical filter screen 9, and the mounting cylinder 1102 is uniformly and vertically fixed to the outside of the collar 1101 along the circumference, and the inner cavity of the mounting cylinder 1102 is connected to the inner side of the collar 1101. The bottom end of the slide rod 1105 is fixedly connected to the top of the cone block 7, the top end of the slide rod 1105 extends to the inner side of the collar 1101, and the slide rod 1105 and the collar 1101 are slidably connected coaxially. The outer side of the slide rod 1105 is uniformly provided with annular grooves 1106 along the axial direction, and multiple sets of annular grooves 1106 form a continuous corrugated concave-convex surface on the outer side of the slide rod 1105. The ball bearing 1103 is slidably mounted inside the mounting cylinder 1102, and the end of the ball bearing 1103 extends to the outside of the mounting cylinder 1102 and fits against the concave and convex surfaces of the annular groove 1106. A compression spring 1104 is disposed inside the mounting cylinder 1102. One end of the compression spring 1104 is fixedly connected to the inner bottom of the mounting cylinder 1102, and the other end of the compression spring 1104 abuts against the surface of the ball 1103.

[0031] During the lifting and lowering process of the slide rod 1105, the corrugated concave and convex surface formed by the outer annular groove 1106 creates relative motion with the ball 1103. The compression spring 1104 continuously pushes the ball 1103, making the ball 1103 tightly fit with the concave and convex surface of the annular groove 1106. When the slide rod 1105 moves upward, the convex surface of the annular groove 1106 pushes the ball 1103 to slide along the inner cavity of the mounting cylinder 1102, while compressing the compression spring 1104. When the concave surface of the annular groove 1106 moves to the inner cavity of the ball 1103, the ball 1103 slides along the inner cavity of the mounting cylinder 1102. At the same time, the compression spring 1104 is compressed. When the ball 1103 is in position, the compression spring 1104 pushes the ball 1103 to reset, so that the ball 1103 is engaged in the concave surface of the annular groove 1106. During this process, the continuous lifting and lowering movement of the slide rod 1105, through the cooperation between the concave and convex surfaces of the annular groove 1106 and the ball 1103, forms a continuous vertical pulse driving force on the collar 1101. The collar 1101 drives the conical filter screen 9 to work in conjunction with the elastic support mechanism 10 to make continuous reciprocating shaking, thereby realizing synchronous screening during the conveying process.

[0032] In this embodiment, the re-cutting mechanism 12 includes a cutter 1201 and a through groove 1202; The through channels 1202 are arranged in a ring array at the edge of the conical filter screen 9. The cutter 1201 is evenly fixed on the inner wall of the hopper 5 along the circumference. The cutting edge of the cutter 1201 faces the conical filter screen 9, and the cutter 1201 slides through the inside of the through channel 1202. The cutter 1201 has a shearing bevel at one end near the top surface of the conical filter 9, which is used to shear the intercepted large fruit pieces when the conical filter 9 reciprocates up and down.

[0033] During the shaking process, the conical filter 9 makes continuous vertical reciprocating lifting and lowering motion. The through groove 1202 opened at the edge of the conical filter 9 moves up and down synchronously with the conical filter 9, and slides vertically back and forth along the cutter 1201 fixed on the inner wall of the hopper 5. The oversized fruit pieces intercepted by the conical filter 9 gather along the conical surface to the edge of the conical filter 9 and fall into the position of the through groove 1202. When the conical filter 9 moves downward, the shearing inclined surface at the end of the cutter 1201 forms a shearing pair with the top surface of the conical filter 9, which forms a continuous shearing action on the large fruit pieces at the position of the through groove 1202, shearing the oversized fruit pieces to the particle size specifications that meet the conveying requirements. The qualified fruit pieces after shearing fall through the mesh of the conical filter 9 to the bottom of the hopper 5, completing the subsequent conveying.

[0034] In this embodiment, the spacing between adjacent cutters 1201 is adapted to the sieve aperture of the conical filter screen 9, which ensures that the maximum size of the fruit pieces cut by the cutter 1201 does not exceed the sieve aperture of the conical filter screen 9, ensuring that the cut fruit pieces fully meet the conveying requirements of the cam rotor pump 2, and preventing large fruit pieces that are not completely cut from entering the cam rotor pump 2; the cutter 1201 is made of food-grade stainless steel, and the blade surface has a mirror polished structure, which makes it difficult for fruit pulp fragments and sugar stains to adhere, and avoids the growth of microorganisms from material residue.

[0035] In this embodiment, the aperture of the conical filter screen 9 is matched with the maximum flow channel diameter of the cam rotor pump 2, which can ensure that the particle size of the fruit falling through the sieve holes is completely matched with the conveying requirements of the cam rotor pump 2; the cone surface inclination angle of the conical filter screen 9 is 15°-30°, which can ensure that the fruit particles stay on the top surface of the filter screen for a moderate time, so as to achieve sufficient screening without causing fruit particle damage due to excessive residence time. Afterwards, the intercepted oversized fruit pieces are collected at the re-cutting mechanism 12 at the edge of the filter screen.

[0036] In this embodiment, a guide slope is provided on the inner side of the top of the fixing ring 1001 to prevent material from accumulating and stagnating at the junction of the fixing ring 1001 and the inner wall of the hopper 5, thus ensuring the smooth feeding of material; the bottom of the guide slope is rounded to prevent sharp corners from scratching or damaging the falling fruit pieces, thus ensuring the integrity of the fruit piece shape.

[0037] In this embodiment, four sets of support rods 1003 are provided. The four sets of support rods 1003 are evenly arranged in a circular array with the axis of the fixing ring 1001 as the center. The included angle between the centers of two adjacent sets of support rods 1003 is 90°.

[0038] The four sets of support rods 1003 can form four points of uniform support at the bottom of the conical filter screen 9, so that the force on each point of the conical filter screen 9 is completely uniform during the shaking process, avoiding the problem of local tilting and shaking displacement of the conical filter screen 9 due to uneven support.

[0039] The solutions in Embodiment 1 and Embodiment 2 will be further described below with reference to their specific working methods. Before the device is started, the fruit chunks with soup to be conveyed are injected into the hopper 5 and fall onto the top surface of the conical filter screen 9. When the device is started, the drive motor 3 runs, synchronously driving the cam rotor pump 2 and the drive pulley 807 to rotate. The drive pulley 807 drives the driven pulley 806 and the drive shaft 805 to rotate synchronously through the connecting belt 808. The drive shaft 805 drives the lever 803 inside the transfer box 4 to rotate in a circular motion. During the rotation of the lever 803, the guide rod 804 at its end controls the rectangular frame plate 801 to slide vertically back and forth along the vertical rod 802, synchronously driving the top rod 6 and the cone block 7 to rise and fall back and forth, synchronously breaking up and clearing the material at the bottom outlet of the hopper 5.

[0040] As the cone block 7 reciprocates, the slide rod 1105 fixed at its top moves vertically and reciprocates in sync with the cone block 7. The corrugated surface of the annular groove 1106 on the outer side of the slide rod 1105, in conjunction with the ball bearing 1103 pushed by the compression spring 1104, can generate a continuous pulse-like driving force on the collar 1101 during the lifting and lowering of the slide rod 1105. The collar 1101 drives the conical filter screen 9 to move synchronously. The support rod 1003 at the bottom of the conical filter screen 9 moves along the outer sleeve 1002. The reciprocating sliding, combined with the compression and rebound of the return spring 1004, causes the conical filter screen 9 to continuously vibrate vertically, synchronously screening the material in the hopper 5. Fruit particles that meet the conveying requirements fall through the screen holes of the conical filter screen 9 and enter the transfer box 4 under the negative pressure adsorption of the cam rotor pump 2, and then complete the continuous conveying through the cam rotor pump 2. Large fruit pieces that exceed the size limit are intercepted by the conical filter screen 9 and automatically gather at the re-cutting mechanism 12 at the edge of the filter screen along the 15°-30° conical surface.

[0041] While the conical filter screen 9 reciprocates and vibrates to screen, the through groove 1202 on the edge of the filter screen rises and falls synchronously with the conical filter screen 9, and slides back and forth along the cutter 1201 fixed to the inner wall of the hopper 5. The oversized fruit pieces that gather at the through groove 1202 are simultaneously sheared to the particle size specifications that meet the conveying requirements under the shearing side effect formed by the shearing inclined surface of the cutter 1201 and the top surface of the conical filter screen 9. The qualified fruit pieces after shearing fall to the bottom of the hopper 5 through the screen holes of the conical filter screen 9 and are conveyed with the mainstream material, realizing the online synchronous reprocessing of large fruit pieces without the need for machine shutdown and diversion.

[0042] The above description is merely a further embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed in the present invention, based on the technical solution and concept of the present invention, shall fall within the scope of protection of the present invention.
