Description

Technical Field

[0001] This utility model relates to the field of feed processing equipment technology, specifically to a weight re-inspection device for bagged premixed feed. Background Technology

[0002] Feed is a general term for the food consumed by all domesticated animals. In a narrower sense, feed mainly refers to the food raised in agriculture or animal husbandry. Classified by the level of meeting animal nutritional needs, feed products can be divided into: complete compound feed, concentrated feed, and premixed feed. In the entire feed production, processing, and distribution chain, the accuracy of bagged portioning is a crucial link in ensuring the compliant operation of feed companies, the rights and interests of downstream users (such as the accuracy of feed formulation at farms), and the safety of logistics and transportation.

[0003] Patent CN 211576309 U discloses a simplified repeatable weighing scale, including a support frame, a tensioning mechanism, and a protective mechanism. The tensioning mechanism is located on the support frame and includes a groove formed inside the support frame. The end of a movable plate is installed inside the groove, and a driven shaft is installed inside the movable plate. A driven wheel is fixed to the outer wall of the driven shaft. A first fixed plate and a second fixed plate are respectively provided on both sides of the movable plate. A weighing sensor is fixed to the bottom of the support frame, and a base is provided at the bottom of the weighing sensor. A display device is provided on the outside of the base, and a collection box is provided at the end of the support frame.

[0004] However, the device still has the following problems: when weighing, it cannot mark unqualified bagged feed in a timely manner. When there are many feed bags on the production line, it is not easy to distinguish unqualified feed, which affects the overall production efficiency. Summary of the Invention

[0005] In order to solve the problems existing in the prior art, a weight re-inspection device for bagged premixed materials is provided to solve the problems mentioned in the above technical background.

[0006] The technical solution adopted by this utility model to solve its technical problem is: This utility model proposes a weight re-inspection device for bagged premixed materials, including a frame, on which a support platform for carrying the packaging bag is slidably connected. The support platform is connected to the frame via a compression spring. A first recording pen and a second recording pen are slidably connected to one side of the support platform. When the support platform descends to different heights, the support platform can drive the first recording pen or the second recording pen to record on the packaging bag.

[0007] Preferably, a recording box is fixed on the support platform, the first recording pen is connected to the recording box via a first spring, and the second recording pen is connected to the recording box via a second spring.

[0008] Preferably, a first electromagnet and a second electromagnet are fixedly disposed on the recording box. The first electromagnet and the second electromagnet have an attractive effect on the first recording pen and the second recording pen, respectively. The magnetic force of the first electromagnet is greater than the elastic force of the first spring, and the magnetic force of the second electromagnet is greater than the elastic force of the second spring.

[0009] Preferably, a detection box is fixed on the frame, and an upper contact and a lower contact are provided inside the detection box. A conductive plate that cooperates with the upper contact and the lower contact is fixed on the support platform.

[0010] Preferably, the upper contact is electrically connected to the first electromagnet, and the lower contact is electrically connected to the second electromagnet.

[0011] Preferably, the upper contact is connected to the detection box via a third spring, and the lower contact is connected to the detection box via a fourth spring.

[0012] Preferably, a first guide rod and a second guide rod are fixed inside the recording box, and a first magnetic plate and a second magnetic plate are slidably sleeved on the first guide rod and the second guide rod, respectively. The first recording pen and the first magnetic plate are threadedly connected, and the second recording pen and the second magnetic plate are threadedly connected.

[0013] Preferably, a conveyor belt is rotatably connected to the support platform, and a motor is connected to the conveyor belt.

[0014] Preferably, guide plates are fixedly installed at both ends of the support platform.

[0015] Preferably, the bottom of the frame has several support legs, and a weighing sensor is fixed to the lower end of each support leg.

[0016] Compared with the prior art, the beneficial effects of this utility model are: This invention features a first recording pen and a second recording pen. When the weight inside the feed bag is within the error range, the support platform descends to the middle position, and both the first and second recording pens cease operation. When the feed bag contains less feed, the support platform descends a smaller distance, allowing the first recording pen to mark the bag. Conversely, when the feed bag contains more feed, the support platform descends a larger distance, allowing the second recording pen to mark the bag. These markings facilitate workers in distinguishing between feed bags that are too light or too heavy, making it easier to adjust the feed amount accordingly.

[0017] This utility model is equipped with an upper contact and a lower contact. The upper contact and the lower contact are connected to the detection box through a third spring and a fourth spring. The third spring and the fourth spring can ensure that when the weight of the feed bag is abnormal and the conductive plate is in a higher or lower position, the conductive plate can maintain continuous contact with the upper contact or the lower contact, so as to ensure that the feed bag with abnormal weight can be marked.

[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0021] refer to Figures 1-8 This embodiment proposes a weight re-inspection device for bagged premixed materials, including a frame 1, on which a support platform 2 for carrying packaging bags is slidably connected. The support platform 2 is connected to the frame 1 by a compression spring. A first recording pen 3 and a second recording pen 4 are slidably connected to one side of the support platform 2. When the support platform 2 descends to different heights, the support platform 2 can drive the first recording pen 3 or the second recording pen 4 to record on the packaging bag.

[0022] The first recording pen 3 or the second recording pen 4 can be an erasable type of recording pen, such as erasable chalk, erasable pen, or erasable ballpoint pen, so that the markings can be easily erased after the materials in the packaging bag have been added or removed.

[0023] Four sliding rods are fixed at the bottom of the support platform 2, and a sliding cylinder is fixed on the frame 1 to allow the sliding rods to slide freely. The sliding rods and the sliding cylinder are fixed together by compression springs.

[0024] A recording box 19 is fixed on the support platform 2. The first recording pen 3 is connected to the recording box 19 through the first spring 5, and the second recording pen 4 is connected to the recording box 19 through the second spring 6.

[0025] The first spring 5 and the second spring 6 ensure that the first recording pen 3 and the second recording pen 4 retract into the recording box 19 in time after recording, so as to avoid smearing the subsequent packaging bag.

[0026] The recording box 19 is fixedly equipped with a first electromagnet 7 and a second electromagnet 8. The first electromagnet 7 and the second electromagnet 8 have an attractive effect on the first recording pen 3 and the second recording pen 4, respectively. The magnetic force of the first electromagnet 7 is greater than the elastic force of the first spring 5, and the magnetic force of the second electromagnet 8 is greater than the elastic force of the second spring 6.

[0027] When the first electromagnet 7 is energized, it generates a magnetic force that attracts the first recording pen 3 to move closer to the packaging bag. At this time, the first spring 5 is stretched and stored, and the first recording pen 3 marks the packaging bag, indicating that the weight of the feed contained in the packaging bag is lower than the standard value. When the second electromagnet 8 is energized, it generates a magnetic force that attracts the second recording pen 4 to move closer to the packaging bag. At this time, the second spring 6 is stretched and stored, and the second recording pen 4 marks the packaging bag, indicating that the weight of the feed contained in the packaging bag is higher than the standard value.

[0028] A detection box 9 is fixed on the frame 1. The detection box 9 is provided with an upper contact 10 and a lower contact 11. A conductive plate 12 that cooperates with the upper contact 10 and the lower contact 11 is fixed on the support platform 2.

[0029] The upper contact 10 is electrically connected to the first electromagnet 7, and the lower contact 11 is electrically connected to the second electromagnet 8.

[0030] The conductive plate 12 is connected in series with the upper contact 10 and the first electromagnet 7; the conductive plate 12 is connected in series with the lower contact 11 and the second electromagnet 8.

[0031] The upper contact 10 is connected in series with the first electromagnet 7, and then in parallel with the lower contact 11 (which is connected in series) and the second electromagnet 8.

[0032] The upper contact 10 is connected to the detection box 9 via the third spring 13, and the lower contact 11 is connected to the detection box 9 via the fourth spring 14.

[0033] Since the weight of different packaging bags is lower than the standard value, the support platform 2 descends under the weight of the packaging bags, and the conductive plate 12 descends with the support platform 2. At this time, under the action of the third spring 13, the upper contact 10 is pushed down by the third spring 13 and maintains continuous contact with the conductive plate 12, which helps to improve the detection range of the upper contact 10 for packaging bags with weights lower than the standard value.

[0034] Similarly, since the weight of different packaging bags is higher than the standard value, the conductive plate 12 descends with the support platform 2. At this time, under the action of the fourth spring 14, the lower contact 11 is pushed down by the fourth spring 14 and maintains continuous contact with the conductive plate 12, which helps to improve the detection range of the lower contact 11 for packaging bags with a weight higher than the standard value.

[0035] The recording box 19 has a first guide rod and a second guide rod fixed inside. A first magnetic plate 15 and a second magnetic plate 16 are slidably sleeved on the first guide rod and the second guide rod, respectively. The first recording pen 3 is threadedly connected to the first magnetic plate 15, and the second recording pen 4 is threadedly connected to the second magnetic plate 16.

[0036] A conveyor belt is rotatably connected to the support platform 2, and a motor is connected to the conveyor belt.

[0037] By placing conveyor belts at the front and rear ends of the bearing platform 2, and cooperating with the conveyor belt on the bearing platform 2, a production line of conveying-weighing-marking-continuing can be realized, which greatly improves the load-bearing efficiency.

[0038] Guide plates 17 are fixedly installed at both ends of the support platform 2.

[0039] The guide plate 17 can keep the packaging bag in the middle of the support platform 2, making it convenient for the recording pen to approach the packaging bag for recording.

[0040] The recording box 19 is fixed on the guide plate 17.

[0041] The bottom of the frame 1 has several support legs, and a weighing sensor 18 is fixed at the lower end of each support leg.

[0042] The load cell 18 is connected to a controller, which can display the value of the load cell 18 for easy recording.

[0043] Specific working principle and usage process: S1: After the packaging bag is filled with feed, it is transported to the carrier platform 2. First, it is guided by the guide plates at both ends of the carrier platform 2 so that the packaging bag is located in the middle of the carrier platform 2. Then, the power of the motor is turned off, and after the carrier platform 2 is stable, the power is turned on so that the conductive plate 12 is energized. S2: When the weight of the packaging bag is lower than the standard value after power is applied, the compression of the spring is small and the height of the carrier platform 2 is small. At this time, it is in a higher position. The carrier platform 2 drives the conductive plate 12 to contact the upper contact 10. After the conductive plate 12 contacts the upper contact 10, the first electromagnet 7 generates a magnetic force, thereby attracting the first recording pen 3 to approach the packaging bag for marking. When the weight of the packaging bag is within the error range of the standard value, the compression of the compression spring is moderate, the descent height of the support platform 2 is moderate, and it is in the middle position. The support platform 2 drives the conductive plate 12 to not contact the upper contact 10 and the lower contact 11. The first electromagnet 7 and the second electromagnet 8 are not energized, and the packaging bag is not marked. When the weight of the packaging bag is higher than the standard value, the compression spring is compressed more and the support platform 2 drops more. At this time, it is in a lower position. The support platform 2 drives the conductive plate 12 to contact the lower contact 11. After the conductive plate 12 contacts the lower contact 11, the second electromagnet 8 generates magnetic force, thereby attracting the second recording pen 4 to approach the packaging bag for marking. S3: After marking the unqualified packaging bags, turn off the power supply connected in series with the conductive plate 12. At this time, turn on the power supply of the motor so that the motor drives the conveyor belt to continue to convey forward. S4: Based on the markings on the packaging bags, the staff remove the unqualified packaging bags from the conveyor belt, adjust the materials inside the packaging bags as needed, and erase the markings on the packaging bags after they are qualified, and then put them back on the production line for subsequent operations.

[0044] Although embodiments of the present invention have been shown and described, those skilled in the art will understand 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 claims and their equivalents.
