Description

Technical Field

[0001] This utility model relates to the field of weighing and packaging technology, and in particular to a dual-mode weighing and packaging device. Background Technology

[0002] With the continuous development of industrial production, especially in industries such as chemicals, food, and pharmaceuticals, the demand for automated packaging systems is increasing. Traditional single packaging methods often cannot meet the packaging needs of products of different specifications and batches. Therefore, improving the flexibility and multi-functionality of packaging equipment has become the key to improving production efficiency and market competitiveness.

[0003] In existing automated weighing and packaging equipment, fixed pipeline systems are commonly used, that is, materials are packaged through a single pipe or conduit. Although this design can meet basic packaging needs, it lacks flexibility and cannot efficiently cope with the needs of different sizes of packaging, resulting in a relatively limited application scenario for the equipment. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing a dual-mode weighing and dispensing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A dual-mode weighing and dispensing device includes a frame, a hopper fixedly connected to the top of the frame, and a new conduit and an original conduit fixedly connected from left to right on the lower inner side of the frame. Two valve plates are respectively located inside the new conduit and the original conduit on both sides of the hopper, and the two valve plates respectively close or open the two sides of the hopper. A support plate is installed on the front side of the hopper, and a drive mechanism is installed on the support plate. The drive mechanism synchronously drives the two valve plates to rotate. A foot switch for controlling the drive mechanism is installed at the bottom of the frame.

[0007] Preferably, the driving mechanism includes a driving assembly and a gear set. The gear set includes a plurality of rotating shafts rotatably disposed on the back of the support plate. A driving gear, half gear I, half gear II and two intermediate rotating gears are respectively fixedly sleeved on the outer wall of the plurality of rotating shafts. The two intermediate rotating gears are located on both sides of the driving gear and mesh with the driving gear respectively. Half gear I and half gear II mesh with the two intermediate rotating gears respectively.

[0008] Preferably, shafts are installed on both sides of the hopper, and the two valve plates are fixedly sleeved on the outer walls of the two shafts. One end of the back of the two rotating shafts connected to the half gear I and half gear II is connected to the two shafts respectively.

[0009] Preferably, the two valve plates are arranged in the same direction of inclination. When the valve plate on the left closes the hopper, the valve plate on the right opens the right side of the hopper. When the valve plate on the left opens the left side of the hopper, the valve plate on the right closes the left side of the hopper.

[0010] Preferably, the drive assembly includes a motor mounted on the front side of the support plate, a worm gear fixedly connected to the output shaft of the motor, and a worm wheel meshing with the worm gear fixedly sleeved on a shaft connected to the drive gear.

[0011] Preferably, a mounting base is fixedly connected to the frame, and two sets of foot switches are set and installed in the mounting base. The two foot switches are electrically connected to the motor respectively, and the two foot switches control the forward and reverse rotation of the motor respectively.

[0012] Preferably, sealing strips I are fixedly connected to opposite sides of both valve plates, and when one of the valve plates closes the hopper, the surface of the sealing strip I on the valve plate contacts the hopper.

[0013] Preferably, sealing strips II are fixedly connected to the opposite sides of the two valve plates. When one of the valve plates closes the hopper, the surface of the sealing strip II on the valve plate contacts the new conduit or the original conduit.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] By adding new conduits and modifying the original structure, the existing structure was fully utilized, reducing modification costs and resource waste. Operators can easily control the forward and reverse rotation of the motor using a foot switch, thereby controlling the opening and closing states of the two valve plates. The two valve plates switch on and off in a corresponding manner, enabling rapid switching between large and small packaging sizes. This meets the needs of different packaging specifications, greatly improves production efficiency and flexibility, and demonstrates significant benefits in meeting diverse packaging requirements, as well as enhancing equipment stability and competitiveness.

Detailed Implementation

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] like Figure 1-5 As shown, this utility model provides a dual-mode weighing and dispensing device, including a frame 100. A hopper 200 is fixedly connected to the top of the frame 100. A new conduit 300 and an original conduit 400 are fixedly connected from left to right on the lower inner side of the frame 100. Two valve plates 500 are provided on both sides of the hopper 200, respectively located in the new conduit 300 and the original conduit 400. The two valve plates 500 respectively close or open the two sides of the hopper 200. A support plate 600 is installed on the front side of the hopper 200. A drive mechanism 700 is installed on the support plate 600. The drive mechanism 700 synchronously drives the two valve plates 500 to rotate. A foot switch 800 for controlling the drive mechanism 700 is installed at the bottom of the frame 100.

[0025] In this embodiment, the drive mechanism 700 includes a drive assembly 701 and a gear set 702. The gear set 702 includes a plurality of rotating shafts 7021 rotatably disposed on the back of the support plate 600. A drive gear 7022, a half gear I 7023, a half gear II 7024 and two intermediate gears 7025 are respectively fixedly sleeved on the outer wall of the plurality of rotating shafts 7021. The two intermediate gears 7025 are located on both sides of the drive gear 7022 and mesh with the drive gear 7022 respectively. The half gear I 7023 and the half gear II 7024 mesh with the two intermediate gears 7025 respectively.

[0026] In this embodiment, shafts 7026 are installed on both sides of the hopper 200, and two valve plates 500 are fixedly sleeved on the outer walls of the two shafts 7026. One end of the back of the two rotating shafts 7021 connected to the half gear I 7023 and the half gear II 7024 is connected to the two shafts 7026 respectively.

[0027] In this embodiment, the two valve plates 500 are set in the same direction of inclination. When the left valve plate 500 closes the hopper 200, the right valve plate 500 opens the right side of the hopper 200. When the left valve plate 500 opens the left side of the hopper 200, the right valve plate 500 closes the left side of the hopper 200.

[0028] In this embodiment, the drive assembly 701 includes a motor 7011 mounted on the front side of the support plate 600. A worm gear 7012 is fixedly connected to the output shaft of the motor 7011. A worm wheel 7013, which meshes with the worm gear 7012, is fixedly sleeved on the shaft 7026 connected to the drive gear 7022. The motor 7011 drives the worm gear 7012 to rotate the worm wheel 7013, which in turn drives the corresponding rotating shaft 7021 to rotate. By utilizing the transmission of the worm gear 7012 and the worm wheel 7013, a large reduction ratio can be achieved, increasing the torque, ensuring smooth transmission, and providing self-locking performance, thereby meeting the transmission requirements.

[0029] In this embodiment, a mounting base 900 is fixedly connected to the frame 100. Two sets of foot switches 800 are configured and installed in the mounting base 900. The two foot switches 800 are electrically connected to the motor 7011 respectively. The two foot switches 800 control the forward and reverse rotation of the motor 7011 respectively. The foot switches 800 and the motor 7011 are used in conjunction with a mature device. Alternatively, a foot switch 800 with a control system can be used to achieve the purpose of controlling the forward and reverse rotation of the motor 7011 by different foot switches 800. This is existing public technology and is well known in various fields. Therefore, it can meet the requirements of this application and will not be described in detail here.

[0030] In this embodiment, sealing strips I501 are fixedly connected to the opposite sides of the two valve plates 500. When one of the valve plates 500 closes the hopper 200, the surface of the sealing strip I501 on the valve plate 500 contacts the hopper 200, and the sealing strip I501 seals the valve plate 500 and the hopper 200.

[0031] In this embodiment, sealing strips II 502 are fixedly connected to the opposite sides of the two valve plates 500. When one of the valve plates 500 closes the hopper 200, the surface of the sealing strip II 502 on the valve plate 500 contacts the new conduit 300 or the original conduit 400, and the sealing strip II 502 seals the valve plate 500 and the new conduit 300 or the original conduit 400.

[0032] How to use and how to work this device:

[0033] The device is modified by a symmetrical weighing and packaging machine. A new conduit 300 is installed on the original structure. The motor 7011 drives the worm gear 7012, which in turn drives the worm wheel 7013 to drive the corresponding rotating shaft 7021, which in turn drives the drive gear 7022 to rotate. The drive gear 7022 drives the two intermediate rotating gears 7025 that mesh with it to rotate. The two intermediate rotating gears 7025 drive the half gear I 7023 and half gear II 7024 to rotate respectively. The half gear I 7023 and half gear II 7024 rotate in the same direction. When the half gear I 7023 and half gear II 7024 rotate, they drive the shaft 7026 to rotate through the rotating shaft 7021 connected to them, thereby realizing the rotation of the two valve plates 500.

[0034] During small packaging, the foot switch 800 controls the motor 7011, which, through the gear set 702, causes the two valve plates 500 to rotate counterclockwise. The right valve plate 500 opens while the left valve plate 500 closes the left side of the hopper 200. The original conduit 400 opens while the new conduit 300 closes, and the weighed material falls into the original conduit 400. During large packaging, another foot switch 800 controls the motor 7011 to rotate in reverse, which, through the gear set 702, causes the two valve plates 500 to rotate clockwise. The left valve plate 500 opens while the right valve plate 500 closes the right side of the hopper 200. The new conduit 300 opens while the original conduit 400 closes, and the weighed material falls into the new conduit 300. This fully utilizes the existing structure, reducing modification costs and resource waste. The flexible switching between the original conduit 400 and the new conduit 300 meets the needs of different packaging specifications, enhancing the equipment's multi-functionality and market competitiveness.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
