Description

Technical Field

[0001] This invention relates to the field of food testing instruments, and more specifically to a crushing, self-cleaning food testing instrument. Background Technology

[0002] Food is typically composed of carbohydrates, fats, proteins, or water. It is a substance that provides nutrition or pleasure to humans or other organisms through eating or drinking. With the improvement of people's living standards and health awareness, improving food quality, reducing the residue of harmful substances in food, and ensuring food quality and safety are important tasks for the current food production and processing industry.

[0003] Nowadays, food products are basically tested using food testing instruments. In actual operation, when staff crush harder foods for testing, existing testing equipment often requires other equipment to crush the food first, and then staff have to manually divide the sample into several parts before putting it into the detector for testing. This process is time-consuming and not convenient to use.

[0004] Therefore, it is necessary to invent a crushing, self-cleaning food testing instrument to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a crushing and self-cleaning food testing instrument. A certain number of sample tubes are fixed by a receiving tray. A hydraulic cylinder controls the control box, which in turn moves the upper grinding disc downwards. The moving upper grinding disc crushes the food. Then, through the cooperation of a transmission component and transmission gears, a rotating shaft drives the upper grinding disc to rotate, grinding the crushed food. The food powder falls into the sample tubes after passing through a filter cartridge. The quality is detected by a pressure sensor, and quantitative filling is performed. This allows the crushing, grinding, and packaging of food to be carried out simultaneously, eliminating the need for manual sample packaging by operators and minimizing errors. During food testing, the interaction between the hydraulic cylinder, rotating table, switching component, transmission component, and transmission gears on the rigid tube allows for cleaning of the upper and lower grinding discs, as well as the upper and lower cleaning discs. This simultaneous testing and cleaning significantly improves work efficiency and makes the instrument more convenient to use, thus overcoming the aforementioned shortcomings in the technology.

A second control valve is installed after the sewage outlet at the bottom of the conical cylinder passes through the bottom plate of the chassis.

[0024] The technical effects and advantages provided by the present invention in the above technical solution are as follows:

[0025] 1. A certain number of sample tubes are fixed by a receiving tray. The control box is controlled by a hydraulic cylinder, which drives the upper grinding disc to move downward. The moving upper grinding disc crushes the food. Then, through the cooperation of the transmission component and the transmission gear, the rotating shaft drives the upper grinding disc to rotate, grinding the crushed food. The food powder falls into the sample tube after passing through the filter cartridge. The quality is detected by the pressure sensor, and quantitative filling is performed. This allows the crushing, grinding and packaging of food to be carried out simultaneously without the need for manual sample packaging by the staff. The error is small. When conducting food testing, the upper and lower grinding discs, as well as the upper and lower cleaning discs, can be cleaned by the cooperation of the hydraulic cylinder, rotating table, switching component, transmission component and transmission gear on the rigid tube. Testing and cleaning can be carried out simultaneously, which not only greatly improves work efficiency, but also makes it more convenient to use.

[0026] 2. By activating the scraper cylinder, the arc-shaped scraper block moves down and fits against the concave part of the upper grinding disc. The upper grinding disc then drives the arc-shaped scraper block to rotate, scraping the food powder to the feeding port. The food powder falls through the feeding port onto the filter screen, and after being filtered by the filter screen, it falls into the lower part of the filter cylinder. When it is necessary to clean the food particles on the filter screen, activate the adjusting cylinder to raise the high-pressure crushing cylinder, and then clean it through the pushing part.

[0027] 3. The cable tray, center hole, hub and partition hole set on the receiving tray can avoid the problem of wire tangling, and the wires are neat and orderly, which is conducive to later maintenance.

[0028] 4. By starting the linear drive, the scraper moves on top of the filter screen. As the scraper moves, it also carries the food particles on the filter screen. Eventually, the food particles gather in the V-shaped collection section until they reach the open collection box, where they will automatically fall into the open collection box and be collected.

[0029] 5. Adjust the height of the receiving plate by loosening the locking bolts, then place the sample tube on the receiving plate, ensuring the bottom of the sample tube contacts the top of the receiving plate. Then activate the clamping cylinder, which extends to secure the sample tube with clamping blocks, thus fixing the sample tube. This method is suitable for fixing sample tubes of different heights and diameters, making it more widely applicable. Attached Figure Description

[0055] 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.

[0056] This invention provides, for example Figure 1-14 The invention relates to a crushing and self-cleaning food testing instrument, which includes a housing 1. A cleaning cylinder 11 and a filter cylinder 12 with a filter screen 121 installed inside are installed through the top plate of the housing 1. The food powder is filtered through the filter screen 121. The centers of the cleaning cylinder 11 and the filter cylinder 12 are on the same straight line. A testing instrument 2 is provided on the side of the filter cylinder 12 away from the cleaning cylinder 11. A pushing part 7 is provided on the outside of the filter cylinder 12. An open collection box 9 that can be detachably installed on the top of the housing 1 is provided on the side of the filter cylinder 12 close to the testing instrument 2.

[0057] The crushing part 3 is located at the top of the filter cylinder 12. The crushing part 3 includes a crushing cylinder 31 that communicates with the filter cylinder 12 and a lower grinding disc 32 that is fixedly installed inside the crushing cylinder 31. An upper grinding disc 35 is located directly above the lower grinding disc 32, and a scraping assembly is located on the top of the upper grinding disc 35.

[0058] The cleaning section 5 is located on one side of the upper grinding disc 35. The cleaning section 5 includes an upper cleaning disc 51 and a lower cleaning disc 52. The lower cleaning disc 52 is located in the upper part of the cleaning cylinder 11. A water inlet should be provided on the lower cleaning disc 52. The water inlet is connected to a water supply device through a pipe. The pipe can be installed through the cleaning cylinder 11. The water supply device can be a tap water pipe.

[0059] The control box 4 is located at the top of the crushing section 3. In the structure, the bottom of the control box 4 is equipped with a hydraulic cylinder 44. The piston rod of the hydraulic cylinder 44 is fixedly connected to the bottom of the control box 4. A rotating table 43 is installed at the bottom of the hydraulic cylinder 44. The rotating body of the rotating table 43 is fixedly connected to the hydraulic cylinder 44. The rotating table 43 can be detachably installed on the top of the machine box 1.

[0060] The switching section 8, located inside the control box 4, includes a switching assembly 81, a transmission assembly 82, a rotating shaft 85, and a rigid tube 84. Both the rotating shaft 85 and the rigid tube 84 pass through the bottom plate of the control box 4 and are rotatably connected to the control box 4 via bearings. The rigid tube 84 can be made of steel. Both the top ends of the rotating shaft 85 and the rigid tube 84 are fitted with transmission gears 86, and both the bottom ends of the rotating shaft 85 and the rigid tube 84 are fitted with flanges. The flange at the bottom of the rotating shaft 85 is bolted to the top of the upper grinding disc 35, and the flange at the bottom of the rigid tube 84 is bolted to the top of the upper cleaning disc 51.

[0061] The quantitative dispensing section 6 is located inside the chassis 1. The quantitative dispensing section 6 includes a rotating base 62 fixed to the top of the bottom plate of the chassis 1 and a receiving tray 61 located above the rotating base 62. The bottom center of the receiving tray 61 is connected to the rotating flange of the rotating base 62. Five receiving ports are opened along the circumference of the receiving tray 61. Each receiving port is provided with a receiving plate 63. A pressure sensor for detecting weight is embedded in the center of the receiving plate 63.

[0062] Specifically, after the sample tube is fixed on the receiving plate 63, the food is placed on top of the lower grinding disc 32. Then, the hydraulic cylinder 44 is activated, which moves the control box 4 downward, thereby moving the upper grinding disc 35 downward. The moving upper grinding disc 35 crushes the food. Then, through the cooperation of the transmission assembly 82 and the transmission gear 86, the rotating shaft 85 drives the upper grinding disc 35 to rotate, grinding the crushed food. The food powder is discharged from the gap between the upper grinding disc 35 and the lower grinding disc 32. At the same time, the scraping assembly feeds the food powder into the top of the filter screen 121. After the food powder is filtered by the filter screen 121, the qualified sample falls into the lower part of the filter cylinder 12. By opening the first control valve 122, the food powder is then processed. Food powder falls into the sample tube. A pressure sensor detects the total mass of the sample tube and the food powder. When the total mass reaches the input mass of the sample tube and the food powder, the first control valve 122 closes. Simultaneously, the rotating base 62 rotates the receiving tray 61 by a certain angle, aligning the next sample tube with the outlet of the first control valve 122 for a second quantitative filling. This allows sample dispensing and food crushing / grinding to occur simultaneously, saving time and eliminating the need for manual sample dispensing by staff, resulting in smaller errors. After crushing, grinding, and dispensing are completed, the sample tube containing the food powder is removed, appropriate testing reagents are added, and it is placed in the detector 2 for testing. During the testing process, the... The feeding section 7 cleans the food particles on the filter screen 121. After cleaning, the hydraulic cylinder 44 controls the control box 4 to move upward, and then the rotary table 43 drives the hydraulic cylinder 44 to rotate 180°, changing the position of the upper cleaning disc 51 and the upper grinding disc 35. Then, the hydraulic cylinder 44 drives the upper grinding disc 35 to contact the bristles on the lower cleaning disc 52. The bristles on the upper cleaning disc 51 contact the lower grinding disc 32. While the lower cleaning disc 52 is rinsing the upper grinding disc 35, the bristles clean the surface of the rotating upper grinding disc 35, removing the food powder adhering to the upper grinding disc 35 and the arc-shaped scraper block 353. After the upper grinding disc 35 is cleaned, the switching component 81 and the transmission component 82 are coordinated to make the transmission component 8... 2. The upper cleaning disc 51 is rotated by meshing with the transmission gear 86 on the rigid tube 84. While the rotating upper cleaning disc 51 washes the lower grinding disc 32, the bristles on the upper cleaning disc 51 clean the food powder adhering to the lower grinding disc 32, resulting in a good cleaning effect. After the lower grinding disc 32 is cleaned, the hydraulic cylinder 44 controls the control box 4 to move upward. Then, the rotary table 43 drives the hydraulic cylinder 44 to rotate 180°, so that the upper grinding disc 35 is reset. After that, the hydraulic cylinder 44 drives the bristles on the upper cleaning disc 51 to contact the bristles on the lower cleaning disc 52. The bristles on the upper cleaning disc 51 are cleaned by the cooperation of the rotating upper cleaning disc 51 and the lower cleaning disc 52, preventing food powder residue on the bristles from affecting the next cleaning.

[0063] It should be noted that, except for detector 2, the other mechanisms are controlled by the same control system, such as an industrial computer with a touch screen.

[0064] To improve the filtration effect, conventional adjustments such as adding a vibrator can be made to the filter screen 121.

[0065] Reference Figure 1-7 To enable free switching between grinding and cleaning modes, facilitate operator use, and improve testing efficiency, a guide plate 87 is provided between the switching component 81 and the transmission component 82. The bottom of the guide plate 87 has a sliding groove 871, and the top of the guide plate 87 is detachably mounted with a movable seat 83. The movable seat 83 has two symmetrically distributed mounting holes. Mounting plates 88 are provided on both sides of one end of the movable seat 83. The mounting plates 88 are fixed to the top of the guide plate 87 by bolts. The switching component 81 includes a first motor 811 fixedly installed inside the control box 4. The output shaft of the first motor 811 is mounted with a lead screw 812. One end of the lead screw 812 is rotatably connected to the inner wall of the control box 4 through a bearing. A nut slide 813 that moves along the lead screw 812 is sleeved on the outer wall of the lead screw 812. The nut slide 813 is fixed in one of the mounting holes.

[0066] The transmission assembly 82 in the structure includes a second motor 821 fixedly installed inside the control box 4 and a worm gear 824 fixedly installed in another mounting hole. The output shaft of the second motor 821 is connected to a transmission rod 822. One end of the transmission rod 822 is rotatably connected to the inner wall of the control box 4 through a bearing. Two symmetrically distributed limiting strips 8221 are fixed on the outer wall of the transmission rod 822. The worm gear 824 is sleeved on the outer wall of the transmission rod 822. Two symmetrically distributed limiting grooves 8241 for cooperating with the limiting strips 8221 are opened on the inner wall of the worm gear 824. Both ends of the worm gear 824 are meshed with worm wheels 823. One side of the worm wheel 823 is meshed with a transmission gear 86. A shaft is inserted and fixed at the center of the worm wheel 823. The bottom end of the shaft is rotatably set on the top of the mounting plate 88.

[0067] In the above scheme, a cover plate 41 is detachably installed on the top opening of the control box 4. A rotary joint needs to be installed through the cover plate 41 (omitted in the figure). One end of the rotary joint is connected to the rigid pipe 84 via a pipe, and the other end is connected to the water supply equipment, such as a tap water pipe, for supplying water to the upward cleaning plate 51. An I-shaped guide rod 42 is fixed on the top of the bottom plate of the control box 4 for limiting the guide plate 87. The I-shaped guide rod 42 is slidably connected to the sliding through groove 871. The guide plate 87 is guided and limited by the I-shaped guide rod 42.

[0068] Specifically, the first motor 811 is started, which drives the lead screw 812 to rotate, causing the nut slide 813 to move the movable seat 83 along the lead screw 812. The movable seat 83 drives the guide plate 87 to slide on the I-shaped guide rod 42, which in turn drives the worm 824 and worm wheel 823 to move. When the worm wheel 823 meshes with one of the transmission gears 86, the second motor 821 is started, which controls the rotation of the worm 824, causing the worm wheel 823 to mesh with the transmission gear 86, which in turn drives the rotating shaft 85 or the rigid tube 84 to rotate, which in turn causes the upper grinding disc 35 or the upper cleaning disc 51 to rotate, thus enabling the grinding of crushed food or the final cleaning work.

[0069] Reference Figure 2-3 and Figure 12-14 To improve the applicability of the present invention, two clamping cylinders 66 arranged face to face are fixed on the outside of each receiving port. The piston rod of each clamping cylinder 66 is fixed with a clamping block 67 for clamping the sample tube. An arc-shaped through groove is opened on the side of the clamping block 67 away from the clamping cylinder 66.

[0070] Each receiving port in the structure is equipped with an adjusting seat 64. A connecting rod 65 is slidably installed in the through hole on the adjusting seat 64. The bottom end of the connecting rod 65 is fixedly connected to the top of the receiving plate 63, and a locking bolt for locking the connecting rod 65 is screwed onto the outer wall of the adjusting seat 64.

[0071] Specifically, open the box door, and adjust the height of the receiving plate 63 after loosening the locking bolts according to the height of the sample tube. This ensures that the sample tube, when placed on the receiving plate 63, can just catch the pulverized food discharged from the outlet of the filter cartridge 12 while preventing the food from falling outside the sample tube. Then, place the sample tube on the receiving plate 63, ensuring that the bottom of the sample tube contacts the top of the receiving plate 63. Then, activate the clamping cylinder 66, which extends to allow the clamping block 67 to stably clamp the sample tube, thus fixing it in place. After fixing the appropriate number of sample tubes, close the box door and manually operate the touch screen of the industrial control computer to select the workstation, sample tube quality, and the quality of the food to be placed in the sample tube. The workstation where the sample tubes are placed can be determined by the serial number marking next to each receiving port, which is set on the top of the receiving tray 61.

[0072] Reference Figure 13-14To avoid cable tangling, the receiving tray 61 has a central hole 611 for the cable to pass through. A cable groove 612 communicating with the central hole 611 is provided on the outside of the central hole 611. The cable grooves 612 are distributed in a ring array at the bottom of the receiving tray 61. A cable collection tube 68 is provided at the top of the central hole 611. The bottom of the cable collection tube 68 is fixedly connected to the top of the receiving tray 61. Several dividing holes 681 for separating cables are provided on the outer wall of the cable collection tube 68 in a ring array. The dividing holes 681 are located at the bottom of the cable collection tube 68.

[0073] Specifically, during wiring, the pressure sensor wires can enter the central hole 611 through the cable groove 612 and then exit through the manifold 68. The cable groove 612 limits the movement of the pressure sensor wires. The control clamping cylinder 66 wires can enter the manifold 68 through the partition hole 681 and then exit through the manifold 68. Finally, the conductive slip ring (which can be installed on the top of the manifold 68) connects each wire to the industrial control computer. This avoids the problem of wire tangling and keeps the wires neat and orderly, which is beneficial for later maintenance.

[0074] Reference Figure 1-3 and Figure 10 In order to automatically collect food particles on the filter screen 121, reduce waste, and facilitate cleaning, the pusher part 7 in the structure includes a scraper 71 and two linear actuators 72. The linear actuators 72 can be electric linear modules. The two linear actuators 72 are located outside the filter cylinder 12 and fixedly installed on the top of the housing 1. The bottom of the scraper 71 is attached to the top of the filter screen 121. The scraper 71 is an integrally formed structure. The scraper 71 includes a V-shaped collecting part 711. Both ends of the V-shaped collecting part 711 are provided with arc-shaped collecting parts 712. The end of the arc-shaped collecting part 712 away from the V-shaped collecting part 711 is provided with an L-shaped connecting part 713. The bottom of the L-shaped connecting part 713 is fixedly connected to the top of the moving body of the linear actuator 72.

[0075] Specifically, the linear drive 72 is activated, causing the scraper 71 to move on top of the filter screen 121. As the scraper 71 moves, it also carries the food particles on the filter screen 121. Eventually, the food particles gather in the V-shaped collection section 711 until they reach the open collection box 9, where they will automatically fall into the open collection box 9 and be collected.

[0076] Reference Figure 1-4 and Figure 11To improve the cleaning effect, both the upper cleaning disc 51 and the lower cleaning disc 52 in the structure are provided with cavities. The bottom and sides of the upper cleaning disc 51 are provided with several water spray holes arranged in a ring array. The top of the upper cleaning disc 51 is provided with a water inlet connected to the rigid pipe 84. Several sets of first bristles 511 arranged in a ring array are fixed at the bottom of the upper cleaning disc 51. The top of the lower cleaning disc 52 is provided with several water spray holes arranged in a ring array. Several sets of second bristles 521 arranged in a ring array are fixed at the top of the lower cleaning disc 52.

[0077] Specifically, the water spray holes on the upper cleaning disc 51 can rinse away food residue on the lower grinding disc 32. Combined with the rotating upper cleaning disc 51, the first brush bristles 511 further clean the food residue on the lower grinding disc 32, resulting in good cleaning. Similarly, the water spray holes on the lower cleaning disc 52 can rinse away food residue on the upper grinding disc 35. Combined with the rotating upper grinding disc 35 and the second brush bristles 521 on the lower cleaning disc 52, the food residue on the upper grinding disc 35 and the arc-shaped scraper block 353 is further cleaned, resulting in good cleaning. After cleaning, the upper cleaning disc 51 resets. The rotation of the upper cleaning disc 51 and the lower cleaning disc 52 automatically cleans the food residue adhering to the first brush bristles 511 and the second brush bristles 521, preventing the food residue from affecting the next cleaning cycle.

[0078] Reference Figure 1-3 and Figure 8-9 To avoid the accumulation of food powder, the scraping assembly in the structure includes a scraping cylinder 351, which is fixed to the top of the upper grinding disc 35. The piston rod of the scraping cylinder 351 is connected to an L-shaped support rod 352. An arc-shaped scraping block 353 is fixed to the bottom end of the L-shaped support rod 352. The two sides of the arc-shaped scraping block 353 are respectively attached to the outer wall of the upper grinding disc 35 and the inner wall of the crushing cylinder 31. The lower part of the upper grinding disc 35 has several feeding ports 321 arranged in a ring array.

[0079] In the structure, a connecting seat 33 is symmetrically installed on the top of the crushing cylinder 31, and an adjusting cylinder 34 is provided at the bottom of the connecting seat 33. The piston rod of the adjusting cylinder 34 is fixedly connected to the connecting seat 33, and the adjusting cylinder 34 is fixed to the top of the casing 1.

[0080] Specifically, during the grinding of crushed food by the rotating upper grinding disc 35, food powder is discharged from the gap between the upper grinding disc 35 and the lower grinding disc 32. The rotating upper grinding disc 35 drives the scraping assembly to rotate. When scraping is required, the scraping cylinder 351 is activated, causing the arc-shaped scraping block 353 to move down and fit against the concave part of the upper grinding disc 35. Then, the upper grinding disc 35 drives the arc-shaped scraping block 353 to rotate, and the arc-shaped scraping block 353 scrapes the food powder to the discharge port 321. The food powder will fall onto the filter screen 121 through the discharge port 321. After being filtered by the filter screen 121, it falls into the lower part of the filter cylinder 12. When it is necessary to clean the food particles on the filter screen 121, the adjusting cylinder 34 is activated to raise the high-pressure crushing cylinder 31, and then the material is cleaned by the pushing part 7.

[0081] In the above scheme, the lower end of the filter cylinder 12 is a conical structure. The discharge port of the filter cylinder 12 is equipped with a first control valve 122, and a sewage discharge hose 13 is provided on one side of the filter cylinder 12. One end of the sewage discharge hose 13 is connected to the sewage discharge port 15 on the bottom plate of the chassis 1. The sewage discharge port 15 is rotatably mounted on the bottom plate of the chassis 1, and a plastic clip 14 for fixing the sewage discharge hose 13 is installed on one side of the front sealing plate of the chassis 1. The sewage discharge hose 13 is fixed by the plastic clip 14. When it is necessary to discharge the sewage in the filter cylinder 12, the sewage discharge hose 13 is connected to the outlet of the first control valve 122. A container for sewage is placed under the sewage discharge port 15 or a pipe for sewage discharge is connected to the sewage discharge port 15. Then the first control valve 122 is opened to discharge the sewage.

[0082] In the above scheme, a bracket 111 for fixing the lower cleaning plate 52 is installed on the upper part of the cleaning cylinder 11. A conical cylinder 112 is provided at the bottom of the cleaning cylinder 11. The sewage outlet at the bottom of the conical cylinder 112 passes through the bottom plate of the casing 1 and is equipped with a second control valve 113. By opening the second control valve 113, the sewage in the cleaning cylinder 11 can be discharged. Before discharging the sewage, a container for holding the sewage needs to be placed below the sewage outlet or the sewage discharge pipe needs to be connected to the outlet of the second control valve 113.

Undoubtedly, 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 foregoing 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.
