Description

Technical Field

[0001] This utility model relates to the field of feed production and processing technology, specifically to a calibration device for a feed batching scale. Background Technology

[0002] A batching scale is a weighing instrument that measures the proportions of several substances in a given quantity. It has a wide range of applications, and can be used for the batching and measurement of multiple materials or for the measurement of a single material. When used with a packaging and sealing machine, it becomes a quantitative packaging scale. A batching scale generally consists of two main parts: the scale body and the feeding mechanism and unloading mechanism, as well as an electrical control system. The scale body needs to be calibrated before it can be used, and the accuracy of the calibration directly affects the efficiency of the batching scale.

[0003] In the prior art, a feed batching scale calibration device with publication number "CN203811264U" includes a batching scale hopper, a gravity sensor, a weighing instrument, weights, and a weight lifting mechanism. The weighing instrument is connected to the gravity sensor, and the central control room is connected to the weight lifting mechanism, which controls the placement and removal of each group of weights in and out of the hopper. The feed batching scale calibration device uses a weighing instrument connected to the gravity sensor to collect changes in the gravity of the batching scale hopper and convert them into digital signals, which are then transmitted to the central control room. The weights are divided into multiple groups, and the central control room can control the placement and removal of each group of weights in and out of the hopper by operating the weight lifting mechanism. The gravity sensor determines whether the weighing display value of the batching scale is consistent with the weight of the standard weights by sensing changes in the gravity of the hopper. Although this device can be set with multiple different calibration points, the accuracy of the batching scale can be quickly and conveniently verified through the central control equipment.

[0004] However, existing technologies still have significant shortcomings, such as:

[0005] After the feed is dispensed from the hopper, a small amount of residual feed will still stick to the inner wall of the hopper. This will cause incomplete dispensing and errors in the dispensing process. In addition, if the feed sticks to the inner wall of the hopper and the feed is then calibrated, and the sticky feed is discharged with the subsequent feed after calibration, the feed scale will have errors again. These errors will affect the accuracy of the calibration. Utility Model Content

[0006] The purpose of this invention is to provide a calibration device for a feed batching scale to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A calibration device for a feed batching scale includes a batching hopper, a support frame fixedly mounted on the outer wall of the batching hopper, a discharge pipe fixedly connected to the bottom of the batching hopper, a feed hopper fixedly connected to the top of the batching hopper, an electronic scale fixedly connected to the bottom of the support frame, a rotating shaft rotatably mounted between the batching hopper and the discharge pipe, a motor fixedly mounted on the top of the batching hopper fixedly connected to one end of the rotating shaft outside the batching hopper, and a spiral auger fixedly mounted in the discharge pipe;

[0009] The rotating shaft is equipped with a scraping mechanism inside the feeding hopper to clean the feed residue on the inner wall of the feeding hopper.

[0010] The batching hopper is equipped with a calibration mechanism for verifying the batching scale.

[0011] Preferably, the scraping mechanism includes two lower claw rings fixedly mounted on a rotating shaft, an upper claw ring slidably mounted on the rotating shaft above the lower claw rings, a connecting rod fixedly mounted on the side of the upper claw ring, a scraping strip fixedly connected to the end of the connecting rod away from the rotating shaft, and a separation mechanism capable of separating the lower claw rings and the upper claw rings is also provided on the rotating shaft.

[0012] Preferably, the calibration mechanism includes a weight pan movably disposed above the motor, several L-shaped rods fixedly disposed below the weight pan, a movable ring slidably sleeved on the side of the rotating shaft near the motor, and the end of the L-shaped rod away from the weight pan slides through the top of the mixing hopper and is fixedly connected to the movable ring.

[0013] Preferably, the separation mechanism includes a fixed ring fixedly disposed on a rotating shaft, a sliding ring slidably disposed on the rotating shaft above the fixed ring, a spring disposed between the rotating shaft and the fixed ring, and a connecting rod fixedly disposed between the side of the sliding ring and the scraper.

[0014] Preferably, the electronic scale includes a base, a movable plate is movably disposed on the base, a weighing sensor is fixedly disposed between the base and the movable plate, and the weighing sensor is electrically connected to the control panel.

[0015] Preferably, a valve is provided below the discharge pipe.

[0016] Preferably, the scraper is L-shaped, and when the lower claw ring and the upper claw ring are combined, the scraper is in contact with the entire inner wall of the feeding hopper.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. By setting up a scraping mechanism, when calibrating the batching scale, a standard weight is placed in the weight pan. The upper and lower claw rings are squeezed by the moving ring, and the scraper is driven by the motor and rotating shaft to scrape the inner wall of the batching hopper. The residual feed on the inner wall can be scraped off and discharged. The weight displayed on the electronic scale is the weight of the entire device and the standard weight. If the standard weight is removed, the weight of the empty device is displayed. This completes the calibration of the batching scale and improves the accuracy of the calibration.

[0019] 2. With the scraping mechanism, when the batching scale is batching sticky feed, some feed may stick to the inner wall of the batching hopper. The scraper can scrape the feed off the inner wall of the batching hopper, ensuring that all the feed of the required weight is discharged without residue, and preventing errors in the batching scale.

[0020] 3. If the feed added to the batching scale is a non-sticky feed, place a standard weight on the weight pan for calibration, remove the standard weight, set the weight to zero through the control panel, and then add the feed to be mixed. This will display the weight of the added feed. At this time, the upper and lower claw rings are separated, and the scraper will not scrape the inner wall of the batching hopper, thereby reducing the wear of the scraper on the inner wall of the batching hopper and reducing the cost of use.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5 This utility model provides a technical solution:

[0029] Example 1:

[0030] A calibration device for a feed batching scale includes a batching hopper 1, a support frame 2 fixedly installed on the outer wall of the batching hopper 1, a discharge pipe 3 fixedly connected to the bottom of the batching hopper 1, a valve 22 installed below the discharge pipe 3, and a feed hopper 4 fixedly connected to the top of the batching hopper 1. The feed to be added is added to the batching hopper 1 through the feed hopper 4. After weighing, the valve 22 is opened and the feed is discharged through the discharge pipe 3.

[0031] An electronic scale 5 is fixedly connected to the bottom of the support frame 2. The electronic scale 5 includes a base 19, on which a movable plate 20 is movably mounted. A weighing sensor 21 is fixedly mounted between the base 19 and the movable plate 20. The weighing sensor 21 is electrically connected to the control panel. The support frame 2 and its components are pressed downward by gravity, which in turn presses the movable plate 20 against the weighing sensor 21. The weighing sensor 21 sends an electrical signal to the control panel, which then displays the weight value. The control panel can reset or set the weight. The electronic scale 5 is existing technology, and those skilled in the art can use other electronic scales 5 as substitutes. Further details are omitted here.

[0032] A rotating shaft 6 is rotatably installed between the feeding hopper 1 and the discharge pipe 3. A motor 7 is fixedly connected to one end of the rotating shaft 6 outside the feeding hopper 1 and is fixedly installed on the top of the feeding hopper 1. A spiral auger 8 is fixedly installed in the discharge pipe 3. When the motor 7 rotates, it drives the spiral auger 8 to rotate in the discharge pipe 3 through the rotating shaft 6, so that the feed in the feeding hopper 1 can be discharged from the discharge pipe 3.

[0033] Inside the feeding hopper 1, the rotating shaft 6 is equipped with a scraping mechanism to clean the residual feed on the inner wall of the feeding hopper 1. The scraping mechanism includes two lower claw rings 9 fixedly mounted on the rotating shaft 6, and an upper claw ring 10 slidably mounted on the rotating shaft 6 above the lower claw rings 9. The upper claw ring 10 can move up and down on the rotating shaft 6. The lower claw rings 9 are fixedly mounted on the rotating shaft 6. A connecting rod 11 is fixedly mounted on the side of the upper claw ring 10. A scraper 12 is fixedly connected to the end of the connecting rod 11 away from the rotating shaft 6. When the upper claw ring 10 moves down to the lower claw ring 9 and merges, the motor 7 drives the rotating shaft 6 to rotate. The rotating shaft 6 drives the lower claw ring 9 to rotate, and then drives the upper claw ring 10 to rotate. The connecting rod 11 fixedly mounted on the side of the upper claw ring 10 drives the scraper 12 to rotate. The scraper 12 then scrapes the inner wall of the feeding hopper 1. The scraper 12 is L-shaped. When the lower claw rings 9 and the upper claw rings 10 merge, the scraper 12 is in contact with the entire inner wall of the feeding hopper 1.

[0034] Example 2:

[0035] The batching hopper 1 is equipped with a calibration mechanism for verifying the batching scale. The calibration mechanism includes a weight pan 13 that is movably mounted above the motor 7. Standard weights can be placed on the weight pan 13. Several L-shaped rods 14 are fixedly mounted below the weight pan 13. A movable ring 15 is slidably mounted on the rotating shaft 6 on the side near the motor 7. The end of the L-shaped rod 14 away from the weight pan 13 slides through the top of the batching hopper 1 and is fixedly connected to the movable ring 15.

[0036] When calibrating the batching scale, a standard weight is placed in the weight pan 13. Due to gravity, the weight on the electronic scale 5 changes. The weight value at this time is the weight of the standard weight and the moving plate 20 and above. At this time, the upper claw ring 10 and the lower claw ring 9 are combined, and the scraper 12 driven by the motor 7 scrapes and discharges the feed residue in the batching hopper 1. After cleaning, the weight at this time is the calibrated mass. If the feed to be weighed later is sticky, the standard weight does not need to be removed, and the weight value can be reset directly through the control panel. If the feed to be weighed later is not sticky, the standard weight is removed, and then the weight value is reset through the control panel.

[0037] Example 3:

[0038] The rotating shaft 6 is also equipped with a separation mechanism that can separate the lower claw ring 9 and the upper claw ring 10. The separation mechanism includes a fixed ring 16 fixedly mounted on the rotating shaft 6, a sliding ring 17 slidably mounted on the rotating shaft 6 above the fixed ring 16, and a spring 18 mounted between the fixed ring 16 and the sliding ring 17. A connecting rod 11 is also fixedly mounted between the side of the sliding ring 17 and the scraper 12. The fixed ring 16 is fixed on the rotating shaft 6, and the sliding ring 17 can slide on the rotating shaft 6. When the standard weight is placed in the weight pan 13, the weight pan 13 moves downward, which drives the movable ring 15 to move downward through the L-shaped rod 14. The movable ring 15 presses the uppermost claw ring 10, which will drive the scraper 12 to move downward. When the scraper 12 moves downward, it drives the connecting rod 11 and the sliding ring 17 above it to move downward and press the spring 18. At this time, the scraper 12 is in full contact with the inner wall of the mixing hopper 1. Starting the motor 7 can scrape and clean the inner wall of the mixing hopper 1.

[0039] If it is not necessary to clean the inner wall of the mixing hopper 1, simply remove the standard weight, the spring 18 will reset, and the sliding ring 17 will move upward. The sliding ring 17 will then move the scraper 12 upward, and the upper claw ring 10 and the lower claw ring 9 will separate. At this time, when the motor 7 rotates, the scraper 12 will not rotate in the mixing hopper 1, and therefore will not scrape.

[0040] Working principle: When calibrating the batching scale, first place the standard weight in the weight pan 13. Under the influence of gravity, it moves downward through the L-shaped rod 14 and the movable ring 15, pressing the uppermost claw ring 10 downward as well. The upper claw ring 10 and lower claw ring 9 then merge together. At this time, the scraper 12 also completely adheres to the inner wall of the batching hopper 1. Then, the motor 7 is started, driving the rotating shaft 6 to rotate. The rotating shaft 6 drives the lower claw ring 9 and upper claw ring 10 to rotate together, allowing the scraper 12 to scrape away any residual feed inside the batching hopper 1. Next, the scraped feed is discharged from the discharge pipe 3 through the screw conveyor 8. Then, the discharged feed is cleaned up. If it is necessary to weigh the sticky feed later, the motor 7 is turned off at this time, and the weight on the electronic scale 5 is reset or set directly through the control panel to complete the calibration. Then, sticky feed is added from the feed hopper 4. After adding the specified weight, the motor 7 is restarted and the valve 22 is opened. The inner wall of the mixing hopper 1 can be scraped while the weighed sticky feed is discharged from the valve 22.

[0041] If the subsequent step is to weigh non-sticky feed, turn off motor 7. At this time, remove the standard weight and reset or set the weight on the electronic scale 5 through the control panel to complete the calibration. Then add non-sticky feed from the feed hopper 4. After adding the specified weight, start motor 7 again and open valve 22. Since the standard weight has been removed, the upper claw ring 10 and the lower claw ring 9 are separated. Motor 7 cannot drive scraper 12 to rotate. The weighed non-sticky feed can only be discharged from valve 22 through auger 8.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
