Description

Technical Field

[0001] This utility model relates to the field of weighing-type empty package detection technology, specifically to a weighing-type empty package detection device for vegetable powder bags. Background Technology

[0002] The vegetable packet in instant noodles is a type of seasoning packet that typically includes a powder packet, a vegetable packet, and a sauce packet. Using the vegetable packet in instant noodles is very simple; just add the seasoning packet to hot water and wait a few minutes before eating.

[0003] The existing Chinese utility model patent with publication number CN207502749U discloses an empty package detection device for food production. It includes a support frame, a support plate between the lower ends of two support frames, an empty package detection box above the middle of the two support frames, a pressure sensor mounting box at the top of the empty package detection box, and an electronic alarm on one side of the box at the outlet of the empty package detection box. The device uses a CCD image pressure sensor to scan the food packaging to be tested. When the CCD image pressure sensor detects an empty package, the electronic alarm sounds, indicating its presence. This helps to remove empty packages containing no food during the food packaging process, improving the pass rate of the finished product and reducing the cost of food production. Simultaneously, the continuous rotation of parallel conveyor rollers drives the continuous conveying of the food packaging to be tested, achieving continuous empty package detection and improving its efficiency.

[0004] Existing empty vegetable packaging detection equipment typically scans the packaging using a CCD image pressure sensor. This method is costly, and the existing equipment cannot remove empty packages after detection, which is very inconvenient. Utility Model Content

[0010] As a preferred embodiment of this utility model, the drive shaft is rotatably connected to the support frame via a bearing, and the left end of the drive shaft on the rear side of the support frame is fixedly connected to the shaft of the drive motor by an insertion method; the support frame can limit the position of the drive shaft.

[0011] As a preferred technical solution of this utility model, the distance between the rear inner wall of the limiting plate and the front end is greater than that of the front end, and the whole is in the shape of a "V" shape. A horizontal baffle structure is provided in the center of the inner side of the limiting plate; the limiting plate can prevent the powdered vegetable bags from stacking.

[0012] As a preferred embodiment of this utility model, a rubber ring is provided on the outer side of the deceleration shaft, and the deceleration shaft and the limiting plate are rotatably connected, with the left and right ends of the deceleration shaft penetrating the limiting plate; the deceleration shaft can limit the speed at which the vegetable bag falls.

[0015] Compared with the prior art, this utility model provides a weighing-type empty package detection device for vegetable powder bags, which has the following beneficial effects:

[0016] 1. This utility model uses a pressure sensor to weigh the powdered vegetable bags above the bracket and transmits the weight data to the controller. The controller sets a weight threshold range. After receiving the weight data, the controller compares the weight data with the threshold range and adjusts the rotation direction of the stepper motor according to the comparison result. When the weight is within the threshold range, the stepper motor drives the sorting disk to rotate 45 degrees clockwise. When the weight is outside the threshold range, the stepper motor drives the sorting disk to rotate counterclockwise. This achieves the effect of empty package detection through weighing. This method does not use CCD equipment, thus reducing equipment costs.

[0017] 2. This utility model utilizes a sorting disc with a ring-shaped baffle structure on its outer side, centered on the disc's center. The angle between adjacent baffles and the disc's axis is 45 degrees. A stepper motor, acting on a controller signal, rotates the sorting disc 45 degrees in different directions. At the initial angle, the gap between the baffles faces the chute. After the vegetable bag falls into the chute, it slides downwards into the bracket under the chute's guidance. A pressure sensor below the bracket weighs the bag. The controller adjusts the stepper motor's rotation direction based on the bag's weight compared to a threshold range, thus moving bags within the threshold range and those outside to the receiving frames on the left and right sides of the base plate, completing the empty bag rejection operation.

[0026] Please see Figure 1 - Figure 4 In this embodiment, a weighing empty bag detection device for vegetable powder packages includes: a base plate 1, a receiving frame 11 fixedly installed on the top of the base plate 1, a support frame 12 fixedly installed on the top of the base plate 1, bearings 13 fitted at the front and rear ends of the support frame 12, a drive shaft 14 inserted inside the bearings 13, a conveyor belt 15 fitted outside the drive shaft 14, a limit plate 16 fixedly installed on the top of the support frame 12, a speed reduction shaft 17 inserted inside the limit plate 16, and a fixedly installed... The base plate 1 is equipped with a drive motor 18. An extension frame 19 is fixedly installed above the base plate 1. A drive motor 110 is fixedly installed above the extension frame 19. A slide groove 111 is fixedly installed on the front side of the limiting plate 16. A pressure sensor 112 is fixedly installed above the base plate 1. A bracket 113 is fixedly installed above the pressure sensor 112. A stepper motor 114 is fixedly installed above the base plate 1. A sorting disk 115 is inserted and installed on the outside of the rotating shaft of the stepper motor 114. A controller 116 is fixedly installed above the limiting plate 16.

[0027] The receiving frame 11 is fixedly installed on the left and right sides of the front end of the base plate 1. The support frame 12 is symmetrically installed on the top of the base plate 1 with the center of the drive shaft 14 as the reference. The drive shaft 14 is rotatably connected to the support frame 12 through the bearing 13. The left end of the drive shaft 14 on the rear side of the support frame 12 is fixedly connected to the rotating shaft of the drive motor 110 by inserting it. The distance between the rear inner wall of the limiting plate 16 and the front end is greater than that of the front end, and the whole is in the shape of a "V". A horizontal baffle structure is set at the center of the inner side of the limiting plate 16. The outer side of the deceleration shaft 17 A rubber ring is provided, and the deceleration shaft 17 and the limiting plate 16 are rotatably connected. The left and right ends of the deceleration shaft 17 pass through the limiting plate 16. The right end of the deceleration shaft 17 is fixedly connected to the rotating shaft of the drive motor 18 by insertion. The top of the bracket 113 has an arc-shaped structure. The top surface of the bracket 113 fits into the outer edge of the sorting disk 115. The outer side of the sorting disk 115 has a baffle structure distributed in a ring with the center of the sorting disk 115 as the reference. The included angle between the adjacent baffles and the axis of the sorting disk 115 is 45 degrees.

[0028] Specifically, the base plate 1 restricts the position of the support frame 12. The front and rear ends of the support frame 12 are provided with openings that engage with the bearings 13. The drive shaft 14 is mounted on the front and rear ends of the support frame 12 via the bearings 13. The left end of the rear drive shaft 14 is fixedly connected to the rotating shaft of the drive motor 110 via an insertion method. When the drive motor 110 starts, it can drive the conveyor belt 15 to rotate via the drive shaft 14, thereby conveying the bagged vegetables above the conveyor belt 15 forward. The limiting plate 16 facilitates the movement of the bagged vegetables to the center of the conveyor belt 15. When the bagged vegetables pass through the center baffle structure of the limiting plate 16, the stacked bagged vegetables will be stopped behind the baffle under the restriction of the baffle, thus preventing the bagged vegetables from stacking into the chute 111. The rotation speed of the deceleration shaft 17... The speed of the falling vegetable bag is limited by the rubber ring on the outside of the speed reduction shaft 17, which increases the friction between the speed reduction shaft 17 and the vegetable bag. The slide 111 facilitates the sliding of the vegetable bag to the top of the bracket 113. The pressure sensor 112 can weigh the vegetable bag and transmit the weighing data to the controller 116. The controller 116 compares the weighing data with the threshold range and adjusts the rotation direction of the stepper motor 114 according to the comparison result. When the weight is within the threshold range, the stepper motor 114 drives the sorting disk 115 to rotate 45 degrees clockwise. When the weight is not within the threshold range, the stepper motor 114 drives the sorting disk 115 to rotate counterclockwise. The baffle structure of the sorting disk 115 can move the vegetable bag into the corresponding receiving frame 11.

[0029] In use, the pressure sensor 112 weighs the packaged vegetables above the bracket 113 and transmits the weight data to the controller 116. The controller 116 sets a weight threshold range. After receiving the weight data, the controller 116 compares the weight data with the threshold range and adjusts the rotation direction of the stepper motor 114 based on the comparison result. When the weight is within the threshold range, the stepper motor 114 drives the sorting disk 115 to rotate 45 degrees clockwise; when the weight is outside the threshold range, the stepper motor 114 drives the sorting disk 115 to rotate counterclockwise. This achieves the effect of empty package detection through weighing. This method does not require CCD equipment, reducing equipment costs. The outer side of the sorting disk 115 has a ring-shaped baffle structure with the center of the sorting disk 115 as the reference, and adjacent baffles... The angle formed between the axes of the sorting disc 115 is 45 degrees. The stepper motor 114 can drive the sorting disc 115 to rotate 45 degrees in different directions according to the signal of the controller 116. When the sorting disc 115 is at the initial angle, the gap between the baffles of the sorting disc 115 is directly opposite the slide 111. After the powdered vegetable bag falls into the slide 111, it will slide down into the interior of the bracket 113 under the guidance of the slide 111. The pressure sensor 112 under the bracket 113 will weigh the powdered vegetable bag. The controller 116 will adjust the rotation direction of the stepper motor 114 according to the comparison result of the weight of the powdered vegetable bag with the threshold range, so as to drive the powdered vegetable bag with the weight within the threshold range and the powdered vegetable bag not within the threshold range to the interior of the receiving frames 11 on the left and right sides of the front end of the base plate 1, and complete the empty bag rejection operation.
