Description

Technical Field

[0001] This invention relates to food industrial processing and conveying equipment technology, specifically a quantitative hot pot base production raw material conveyor. Background Technology

[0002] As is widely known, hot pot base, a key representative of Chinese compound seasonings, relies heavily on the precise proportions of various ingredients (such as butter, chili peppers, Sichuan peppercorns, broad bean paste, and compound spices) for flavor stability. In industrial production, raw materials must undergo automated weighing, conveying, and dispensing processes to ensure batch consistency and food safety. Therefore, developing a conveying device capable of high-precision, high-efficiency, and intelligent quantitative dispensing is a crucial step in improving the intelligent manufacturing level of hot pot base.

[0003] However, existing technologies mostly employ separate feeding systems using electronic weighing and pneumatic / electric valves, which suffer from complex structures, high costs, and susceptibility to oil contamination and high-temperature environments. While some simpler mechanical devices are lower in cost, they lack the ability to dynamically judge the weight of raw materials, cannot automatically identify material shortages or overloading, and still require manual verification, making it difficult to guarantee feeding accuracy. Furthermore, traditional conveyor baskets are prone to swaying during operation, and the feeding action is separated from the weighing process, leading to low efficiency, accumulated errors, and affecting the consistency of the final product's flavor. Therefore, there is an urgent need for a new type of conveying device that integrates automatic weighing identification, anomaly interception, and precise feeding to overcome these shortcomings. Summary of the Invention

When the basket containing hot pot base ingredients is suspended in the hook, the clamp is passively lowered to a certain height according to the weight of the ingredients in the basket. The suspension locking mechanism, in conjunction with the unloading mechanism, limits the hook. Only when the weight of the ingredients in the basket is within a predetermined range and is transported to the feeding point can the hook be flipped down to open and the basket be lowered to the feeding point.

[0008] As a further description of the above technical solution: a sliding ball is provided at the top of the U-shaped lever and at the sliding contact connection point of the U-shaped lever.

[0009] As a further description of the above technical solution: a fixed plate is slidably connected to the top of the U-shaped lever, the fixed plate is fixedly attached to the inner side wall of the auxiliary frame, and the end of the U-shaped lever passing through the fixed plate is movably inserted into both sides of the clamp. A pressing plate is also fixedly connected to the top of the U-shaped lever, and a return spring is connected between the pressing plate and the fixed plate.

[0010] As a further description of the above technical solution: the suspension locking mechanism includes a bottom rod fixedly connected to the bottom end of the contact plate with a groove inside. The bottom rod has slide rails on both sides. The bottom end of the slide rail is recessed inward to form an inner guide rail. A gear is slidably connected in the groove. Side clips are detachably meshed on both sides of the gear. The side clips are fixedly set on the surface of the slide plate. The slide plate is slidably connected in the slide rail and the inner guide rail. The bottom of the inner guide rail is connected to a base plate by a compression spring.

[0011] As a further description of the above technical solution: the suspension locking mechanism also includes a bottom clip fixedly installed at the bottom of the slide groove, the bottom clip being detachably engaged with the bottom of the gear.

[0012] As a further description of the above technical solution: the suspension locking mechanism also includes a connecting rod that is connected to the gear through a force-relieving mechanism.

[0015] In the above technical solution, the quantitative hot pot base production raw material conveyor provided by the present invention has the following beneficial effects: 1. Achieve automatic quantitative identification and accurate dispensing of raw materials: The weight of the basket drives the clamp to move downward, which in turn drives the gears and the positioning mechanism. Dispensing is only allowed when the weight of the raw materials is within the preset qualified range. No external electronic scale or sensor is required to complete the mechanical automatic weighing judgment, ensuring the accurate proportion of raw materials for each batch.

[0016] 2. Effectively ensures consistent flavor of hot pot base: The amount of key ingredients such as spices, butter, and broad bean paste added directly affects the taste of the base. This device uses a mechanical structure to forcefully control the feeding accuracy, avoiding human error or equipment drift, and significantly improving the batch stability and quality uniformity of the product.

[0017] 3. Automatic interception function for unqualified materials: When raw materials are insufficient (e.g., missing) or overweight (e.g., clumping, mixed), the gears are locked by the side or bottom clamps respectively, and the servo motor cannot start to rotate, thereby automatically preventing abnormal basket delivery and preventing inferior or incorrectly proportioned materials from entering subsequent processes.

[0018] 4. Compact structure and high integration, suitable for industrial production lines: The device is directly integrated into the conveyor and uses gravity and mechanical linkage to complete the entire process of weighing-locking-judgment-dispensing. No additional weighing station or complex control system is required, saving space and making it easy to seamlessly connect with existing automated hot pot base production lines.

[0019] 5. Enhance food safety and intelligent production: reduce human intervention and lower the risk of cross-contamination; at the same time, achieve "hard" quality control through pure mechanical logic, which meets the high standards of the food industry for process traceability and error prevention, and helps build smart factories.

Detailed Implementation

[0023] 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.

[0024] Please see Figures 1-10 This invention provides a technical solution for a quantitative hot pot base production raw material conveyor: including: a conveyor 1, with a connecting seat 2 installed on the conveyor 1; and further including: Clamp 3 is movably connected to the bottom of connector 2; Auxiliary frame 4 is fixedly installed on both sides of clamp 3; Hook 6 is rotatably mounted on both sides of the bottom of the connecting seat 2; The suspension locking mechanism is connected to the clamp 3 and the hook 6. When the basket containing hot pot base ingredients is suspended in the hook 6, the clamp 3 is passively lowered to a certain height according to the weight of the ingredients in the basket. The suspension locking mechanism, together with the unloading mechanism, limits the hook 6. Only when the weight of the ingredients in the basket is within the predetermined range and is transmitted to the feeding point can the hook 6 be driven to flip down and open, so that the basket can be lowered to the feeding point.

[0025] In another embodiment of the present invention, preferably, the top end of the spring rod 25 is fixedly connected to the bottom center position of the connecting seat 2, and the bottom end of the spring rod 25 is connected to the top center position of the clamp 3.

[0026] In another embodiment of the present invention, the bottom sides of the connecting seat 2 are fixedly connected to the top of the abutment plate 9. The bottom of the abutment plate 9 is movably inserted into the two sides of the clamping seat 3 through the limiting strip 10. The two sides of the abutment plate 9 slide against the top of the U-shaped lever 11. A pivot is provided at the bend of the U-shaped lever 11, and a pivot is provided at the upper middle position of the U-shaped lever 11 to connect to the inner wall of the auxiliary frame 4. The bottom of the U-shaped lever 11 passes through the inner side of the bottom of the auxiliary frame 4 and is movably connected to the positioning plate 7. A pulley 8 is provided on the inner side of the positioning plate 7.

[0027] In another embodiment of the present invention, a sliding ball 26 is provided at the top of the U-shaped lever 11 and at the sliding contact connection point of the U-shaped lever 11.

[0028] In another embodiment of the present invention, a fixing plate 15 is slidably connected to the top end of the U-shaped lever 11. The fixing plate 15 is fixedly attached to the inner side wall of the auxiliary frame 4, and the end of the U-shaped lever 11 passing through the fixing plate 15 is movably inserted into both sides of the clamp 3. A pressing plate 16 is also fixedly connected to the top end of the U-shaped lever 11, and a return spring 17 is connected between the pressing plate 16 and the fixing plate 15.

[0029] In the industrial production of hot pot base, in order to ensure the consistency of the flavor of the hot pot base, the various raw materials of the hot pot base are usually quantitatively added into the production equipment. Therefore, a quantitative hot pot base conveyor 1 is used to transport the raw materials into the production equipment for production. Depending on the required weight of different raw materials, only different clamps 3 need to be selected. The different clamps 3 are adapted to the different feeding weights of the raw materials by adjusting the length of the internally installed spring rod 25 and slide 14 to accommodate different feeding weights for automatic feeding. In another embodiment of the present invention, the suspension locking mechanism includes a bottom rod 12 fixedly connected to the bottom end of the contact plate 9, which has a groove 14 inside. The bottom rod 12 has slide rails 28 on both sides. The bottom end of the slide rails 28 is recessed inward and has an inner guide rail 29. A gear 13 is slidably connected in the groove 14. Side clips 20 are detachably meshed on both sides of the gear 13. The side clips 20 are fixedly set on the surface of the slide plate 19. The slide plate 19 is slidably connected in the slide rails 28 and the inner guide rails 29. The bottom of the inner guide rails 29 is connected to a base plate 30 by a compression spring 21.

[0030] In another embodiment of the present invention, the suspension locking mechanism further includes a bottom clip 18 fixedly disposed at the bottom of the slide groove 14, and the bottom clip 18 is detachably engaged with the bottom of the gear 13.

[0031] In another embodiment of the present invention, the suspension locking mechanism further includes a connecting rod 27 connected to the gear 13 via a force-relieving mechanism. The connecting rod 27 is rotatably connected to the inner side wall of the side plate 5 and rotatably connected to the top of the hook 6. The hook 6 is symmetrically arranged on both sides of the inner side of the side plate 5, and the side plate 5 is fixedly installed on both sides of the bottom of the clamp 3.

[0032] Based on the above adjustments, the clamp 3 is fixedly installed on the bottom of the connecting seat 2 of the suspension transmission connection on the conveyor 1. The conveyor 1 has the following functions: 1. When conveying raw materials, after placing the raw materials in the basket and suspending the basket on the hook 6, if the weight of the raw materials in the basket is insufficient, when the basket is conveyed to the feeding position by the conveyor 1, even if the servo motor in the hook 6 starts to rotate, it cannot drive the hook 6 to rotate downward, resulting in the two sets of hooks 6 being in a closed state, and the basket cannot be lowered. 2. Only when the weight of the raw material in the basket reaches the set weight range, after the basket is transported to the feeding position by the conveyor 1, can the servo motor drive the hook 6 to flip down and open, thereby dropping the basket downwards. 3. When the weight of the raw material in the basket exceeds the set weight range, the hook 6 will not be able to flip down and open when the basket reaches the placement position, and the conveyor 1 will continue to carry the basket forward. At this point, the staff can re-weigh the raw materials in the unloaded baskets based on the fact that the baskets have not been lowered from the conveyor 1, thereby adjusting the weight of the raw materials to be loaded. The specific structure involved in achieving the above functions is as follows: When conveying and feeding the raw materials for hot pot base, the raw materials are pre-weighed and placed in the basket, which is then suspended in the clamp 3. The specific suspension operation and structural design are as follows: Place the basket containing the raw materials onto the workbench. The basket can be connected to the hook 6 using the workbench's lifting mechanism. Alternatively, the connecting seat 2 on the conveyor 1 can be set to a height-adjustable state, or the basket can be suspended. Various suspension methods are possible. This description uses a lifting workbench as an example. After placing the basket on the workbench, the workbench is raised, lifting the basket upwards. During this lifting process, the basket passes between two sets of positioning plates 7 at the bottom of the auxiliary frame 4, which are adapted to the basket's size and shape, and is lifted upwards. The lifting ring at the top of the basket first contacts the bottom of the two sets of hooks 6 at the bottom of the clamp 3. The upward pressing force of the lifting ring on the hooks 6 opens the hooks 6. As the lifting ring continues to lift upward, the lifting ring is inserted into the hooks 6 and then separates from the hooks 6. At this time, the hooks 6 rotate downward to reset, and the ends of the two sets of hooks 6 contact each other, thereby closing the inside of the hooks 6. At this time, the worktable lowers its height, and the basket lowers its height accordingly. At this time, the lifting ring contacts and presses the inside of the hooks 6. The lifting ring is blocked by the hooks 6, thereby suspending the basket on the conveyor 1. At this time, the hot pot base ingredients are placed inside the basket. The weight of the ingredients will pull the hook 6 downwards, causing the clamp 3 to fall a certain height. The top of the clamp 3 is fixedly connected to both ends of the bottom of the connecting seat 2. The two ends of the spring rod 25 are respectively connected to the bottom of the connecting seat 2 and the top of the clamp 3. At this time, the clamp 3 moves downwards and gradually separates from the connecting seat 2. The clamp 3 will then pull the spring rod 25 downwards, and the abutment plates 9 that were originally inserted into both sides of the clamp 3 will gradually be pulled out from the clamp 3. Figure 5As shown, the shape of the contact plate 9 is such that, during the upward movement of the contact plate 9, it abuts against the top of the U-shaped lever 11. The U-shaped lever 11 has pivots at both the upper middle position and the turning point. The pivot at the middle position is connected to the inner wall of the auxiliary frame 4, ensuring the movement of the U-shaped lever 11 within the auxiliary frame 4. This also ensures that even a small movement at the top of the U-shaped lever 11 can drive a longer movement at the bottom. The top of the U-shaped lever 11 is abutted by the contact plate 9. Simultaneously, a fixing plate 15 is slidably connected to the top of the U-shaped lever 11, and the fixing plate 15 is fixedly attached to the inner wall of the auxiliary frame 4, allowing the end of the U-shaped lever 11 passing through the fixing plate 15 to be movably inserted. Sliding balls 26 are provided on both sides of the clamp 3 to contact the surface of the contact plate 9, which facilitates sliding on the surface of the contact plate 9. The top of the U-shaped lever 11 is also fixedly connected to the pressing plate 16. A return spring 17 is connected between the pressing plate 16 and the fixed plate 15 to facilitate the reset of the U-shaped lever 11. After the top of the U-shaped lever 11 is pressed by the contact plate 9, based on the principle of lever, the bottom end of the U-shaped lever 11 is contracted inward, thereby encircling the outer periphery of the basket by the two sets of positioning plates 7 connected to the bottom end of the U-shaped lever 11, thereby assisting in fixing the basket and preventing the basket from swaying left and right during the suspension and transportation process. The pulley 8 set on the inner side of the positioning plate 7 connected to the bottom end of the U-shaped lever 11 has a certain elastic deformation capability. The raw materials inside the basket fall to a certain height due to their own weight. During the fall, the contact plate 9 gradually slides upward from the clamp 3. Since the position of the contact plate 9 is fixed, the clamp 3 moves downward accordingly. At this time, the bottom rod 12 connected to the bottom end of the contact plate 9 slides downward with the clamp 3, which will cause the gear 13 of the connecting hook 6 to slide downward in the groove 14 opened in the bottom rod 12. Combined with appendix Figure 6 As shown, attached Figure 6 The internal structural diagrams of the three base rods 12 from left to right are as follows: the position of gear 13 in the initial state (left), the position of gear 13 when the set material weight range is reached (middle left), the position of gear 13 when the set material weight range is exceeded (middle right), and the position of gear 13 meshing with base plate 18 (right). When the weight of the raw material placed in the basket pulls the clamp 3 down and causes it to fall, the gear 13 will mesh with the side clip 20 provided on the surface of the slide plate 19 that was originally located at the top of the slide rail 28, and the side clip 20 and the gear 13 will slide down synchronously. The slide rail 28 is opened on both sides of the slide groove 14. When the weight of the raw materials placed in the basket reaches the set weight range, the slide plate 19 will slide into the interconnected inner guide rail 29 at the bottom of the slide rail 28 due to the downward pulling force of the gear 13. The slide plate 19 will be squeezed and contracted into the inner guide rail 29 by the restriction of the bottom side wall of the slide rail 28, thereby separating the side clip 20 on the surface of the slide plate 19 from the gear 13 and losing the restriction on the rotation of the gear 13. At this time, when the conveyor 1 transports the basket to the workbench at the feeding position, the servo motor connected to the gear 13 will start and drive the gear 13 to rotate. Since the gear 13 is not restricted and can rotate, the servo motor can drive the gear 13 to rotate and drive the two sets of hooks 6 to flip down and open. Specifically, the left hook 6 rotates clockwise and flips down to open, and the right hook 6 rotates counterclockwise and flips down to open. When the weight of the raw materials placed in the basket does not reach the set weight range, the slide plate 19 does not retract into the inner guide rail 29. The side clips 20 on the surface of the slide plate 19 will abut against both sides of the gear 13. Even after reaching the position, the servo motor drives the gear 13 to rotate. Due to the restriction of the gear 13 by the side clips 20, and the unloading mechanism unloading the transmission force of the servo motor, the gear 13 cannot rotate. This results in the hook 6 not being able to flip down and open. At this time, the conveyor 1 will continue to drive the basket to move forward. Similarly, when the weight of the raw materials placed in the basket exceeds the set weight range, the gear 13 will slide directly to the bottom of the slide 14, causing the gear 13 to engage with the bottom clip 18 set at the bottom of the slide 14, thus engaging the bottom clip 18 with the gear 13 and limiting the gear 13. This, in conjunction with the unloading mechanism, prevents the rotation of the gear 13 from causing the hook 6 to flip open. Combined with appendix Figure 7 As shown, after the slide plate 19 is inserted into the inner guide rail 29, it will compress the spring 21 by the base plate 30. After the gear 13 separates from the side clip 20, the gear 13 loses its restriction on the side clip 20. At this time, the compression spring 21 rebounds, and the slide plate 19 and the side clip 20 are reset to the bottom of the slide rail 28. After the basket is removed, the height of the clamp 3 increases, and the gear 13 drives the slide plate 19 and the side clip 20 to slide upward and reset in the slide rail 28.

[0033] In another embodiment of the present invention, the unloading mechanism includes a transmission disk 22 connected to a servo motor. The transmission disk 22 is located at the middle end of the connecting rod 27. The outer periphery of the transmission disk 22 is movably connected to the inner side of the gear 13. A limit ball 23 is provided on the outer periphery of the transmission disk 22. The limit ball 23 is slidably inserted into a limit hole 24. The limit hole 24 is correspondingly opened on the inner periphery of the gear 13.

[0034] In another embodiment of the present invention, preferably, one end of the limiting hole 24 is vertical and can provide resistance and restriction, and the other end is inclined.

[0035] The unloading mechanism only restricts the gear 13 from rotating downwards in the direction that drives the hook 6 to flip, but does not restrict the upward rotation of the hook 6. The specific structure is as follows: Combined with appendix Figure 9 As shown, a servo motor is installed inside the connecting rod 27 and drives the transmission disk 22. Limiting balls 23 are evenly spaced on the outer periphery of the transmission disk 22. The transmission disk 22 is rotatably inserted into the center position of the gear 13, and the limiting balls 23 are correspondingly inserted into the limiting holes 24. The limiting holes 24 are correspondingly opened on the inner periphery of the gear 13, and the shape of the limiting holes 24 is combined with the attached... Figure 10 As shown, one end is a vertical resisting and limiting structure, and the other end is inclined. This inclined design provides a certain resisting and limiting force while also allowing the limiting ball 23 to slide. It should be noted that since the left hook 6 is opened by flipping downwards and rotating clockwise, the limiting hole 24 of the gear 13 corresponding to the left hook 6 is set so that when the basket is hanging, the hook 6 can only be flipped upwards and rotated clockwise, and cannot be flipped downwards and rotated counterclockwise. Therefore, the limiting hole 24 is set so that the vertical end faces the direction of counterclockwise rotation of the transmission disk 22, while the inclined end of the limiting hole 24 faces the direction of clockwise rotation of the transmission disk 22. The right hook 6 is symmetrical to this. The setting of the limiting hole 24 in the unloading mechanism here ensures that the two sets of hooks 6 can only rotate upwards freely, which facilitates the installation of the basket by pressing the hooks 6 upwards through the lifting ring. After the basket is suspended in the hook 6, only when the weight of the raw material in the basket reaches the set range, at this time, the rotation of the gear 13 is not restricted. When the servo motor drives the hook 6 (taking the left hook 6 as an example) to rotate clockwise, the limiting ball 23 will abut against the vertical end of the limiting hole 24, thus treating the transmission disk 22 and the gear 13 as a whole to rotate clockwise (the same applies to the right hook 6 in the opposite direction), so that the hook 6 can be rotated downwards to open. When the weight in the basket is insufficient or excessive, or when the basket has not moved to the feeding worktable, the hook 6 cannot be rotated downwards to open. The limiting condition here is that the servo motor is set with a fixed program. The servo motor will only start working and rotating when it reaches the feeding worktable. This limiting program is a common existing technology in industrial production and will not be elaborated on here.

[0036] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. 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.
