Description

Technical Field

[0001] The utility model relates to the technical field of sorting, in particular to an automatic weighing and screening device. Background Art

[0002] The weighing principle of automatic weighing and screening mainly relies on weighing sensors and controllers. When the product enters the weighing area, the weighing sensor will detect the weight of the product and transmit the detected signal to the controller. The controller will select the signal in the stable signal area for processing to obtain the accurate weight of the product. This weight will be compared with the pre-set weight range. Based on the comparison results, the controller will decide whether to reject or classify the product.

[0003] When the existing various types of weighing and screening machines are in operation, it is usually necessary to place the items to be screened on a conveyor belt. With the help of the continuous movement of the conveyor belt, the items can be smoothly transported. During this period, the weighing sensor on the inside of the conveyor belt and the matching controller will jointly perform accurate weighing detection on the items and record the obtained data in detail. Subsequently, these weighing data will be converted into corresponding signals and transmitted to the air push rod system connected to the screening machine. When the item is conveyed to a specific position and aligned with the air push rod, the air push rod will start quickly and try to accurately push the item to the preset collection box next to it.

[0004] However, during this series of operations, due to the inevitable friction between the conveyor belt and the objects, when the air push rod applies thrust to the objects, the objects are not immediately pushed out in a straight trajectory, but are affected by the friction and present an arc motion trajectory. This non-straight motion trajectory greatly increases the risk that the objects cannot accurately fall into the collection frame, thereby affecting the overall efficiency and accuracy of the screening machine. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide an automatic weighing and screening device to solve the technical problem that there is inevitable friction between the conveyor belt and the objects, and when the air push rod applies thrust to the objects, the objects are not immediately pushed out in a straight line.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automatic weighing and screening device, comprising a conveyor belt, a cylinder is provided on one side of the conveyor belt, a push plate is provided at the end of the cylinder, a limiting mechanism is provided on one side of the push plate, the limiting mechanism comprises a movable rod, a connecting rod is provided between the movable rod and the push plate, and a limiting plate is provided on one side of the top of the movable rod.

[0007] By adopting the above technical solution, the limit plate limits and blocks the object to be measured, which is mainly reflected in that it can reduce the deviation and rolling of the object to be measured during the transmission process, ensure the stability and integrity of the object. Through the limit blocking, the object to be measured can maintain a straight line motion trajectory when being pushed, avoiding arc motion caused by friction, thereby improving the accuracy and controllability of the object movement.

[0008] Furthermore, one end of the connecting rod is rotatably connected to the push plate, and the other end of the connecting rod is rotatably connected to the movable rod.

[0009] By adopting the above technical solution, the push plate is ensured to be smooth and flexible when pushing the tested object, thereby protecting the tested object from damage during the screening process to the greatest extent.

[0010] Furthermore, the movable rod is rotatably connected to one side of the conveyor belt via a rotating shaft.

[0011] By adopting the above technical solution, the movable rod and the limit plate can rotate steadily and smoothly under the push of the push plate, ensuring the stability and reliability of the movable rod and the limit plate during rotation, and avoiding failure or damage caused by loose connection.

[0012] Furthermore, a plurality of the cylinders are provided, and the plurality of the cylinders are linearly arranged at equal distances along the length line of the conveyor belt.

[0013] By adopting the above technical solution, it means that multiple push plates can be simultaneously operated on the conveyor belt to perform pushing operations, thereby improving the processing speed of the tested objects. The parallel operation of multiple cylinders makes the entire screening process more efficient and performs multi-stage screening operations.

[0014] Furthermore, a plurality of guide frames for guiding the measured objects are arranged on the other side of the conveyor belt, and the guide frames are opposite to the push plates.

[0015] By adopting the above technical solution, these guide frames correspond to the positions of the objects to be measured, ensuring that the objects to be measured can accurately enter the guide frames when being pushed, helping to guide the objects to be measured to move along a predetermined path and prevent them from deviating from the direction or colliding with other objects during the transmission process.

[0016] Furthermore, a visual inspection mechanism for secondary inspection of the inspected object is provided on one side of the top of the conveyor belt.

[0017] By adopting the above technical solution, the visual inspection mechanism arranged on the top side of the conveyor belt can perform secondary inspection on the objects being inspected, which means that before the objects are pushed and collected, the visual inspection mechanism can check the quality, quantity or other relevant characteristics of the objects again to ensure the accuracy and reliability of the screening process.

[0018] Furthermore, the visual inspection mechanism includes a support frame, an industrial camera is arranged on the inner side of the support frame, and the industrial camera is vertically opposite to the conveyor belt.

[0019] By adopting the above technical solution and providing a support frame, the visual inspection mechanism can be firmly installed on the top side of the conveyor belt, thereby ensuring the stability and safety of the industrial camera during the inspection process.

[0020] Furthermore, a control panel is provided on the outer side of the conveyor belt, and the control panel is used to control the conveyor belt and the cylinder.

[0021] By adopting the above technical solution, the control panel enables the operator to conveniently control the conveyor belt and the cylinder in real time. As a human-computer interaction interface, the control panel provides an intuitive and concise operating interface, reducing the difficulty of operation.

[0022] Furthermore, the movable rod, the connecting rod, and the limiting plate are all made of stainless steel.

[0023] By adopting the above technical solution, stainless steel is selected as the material to ensure the structural strength and stability of these components during the operation of the screening device. Stainless steel, as a high-strength, corrosion-resistant material, can withstand greater mechanical stress and external impact, thereby extending the service life of the components.

[0024] In summary, the utility model mainly has the following beneficial effects:

[0025] 1. The utility model sets the limit plate and the conveyor belt in a parallel state through the limit mechanism, which plays a key role in limiting and blocking the objects to be tested. Since the objects to be tested are effectively limited during the transmission process, they will be more stable when being pushed, and will not be offset or rotated due to the friction of the conveyor belt. This stability ensures that the objects to be tested can move in a straight line according to a predetermined trajectory. At the same time, the objects to be tested can accurately pass through the guidance of the guide frame during the linear motion, and finally fall smoothly to the predetermined collection position, which not only simplifies the collection process, but also greatly improves the collection efficiency and convenience of the objects to be tested. Therefore, through the limiting effect of the limit plate, the entire screening and collection process can be optimized, which brings significant convenience to the operator;

[0026] 2. The utility model is provided with a visual detection mechanism, which can perform real-time and accurate detection of the objects to be detected on the conveyor belt. By capturing and analyzing the image information of the objects, the visual detection mechanism can quickly identify the key features such as the quantity, position, and shape of the objects, providing reliable data support for subsequent sorting and processing. At the same time, the introduction of the visual detection mechanism improves the automation level and intelligence of the entire screening device. It can automatically complete the detection and identification of the objects to be detected without human intervention, greatly reducing the labor intensity of the operators and improving production efficiency.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0033] The following describes an embodiment of the utility model based on its overall structure. Embodiment 1:

[0034] An automatic weighing and screening device, such as Figure 1-Figure 4As shown, it includes a conveyor belt 1, a cylinder 301 is arranged on one side of the conveyor belt 1, a push plate 302 is arranged at the end of the cylinder 301, a limiting mechanism 5 is arranged on one side of the push plate 302, the limiting mechanism 5 includes a movable rod 501, a connecting rod 502 is arranged between the movable rod 501 and the push plate 302, and a limiting plate 504 is arranged on the top side of the movable rod 501. The limiting plate 504 performs limiting blocking on the object to be measured, which is mainly reflected in that it can reduce the deviation and rolling of the object to be measured during the transmission process, ensure the stability and integrity of the object, and through the limiting blocking, the object to be measured can maintain a straight line motion trajectory when being pushed, avoiding arc motion caused by friction, thereby improving the accuracy and controllability of the object movement, and at the same time, after the object to be measured moves in a straight line, it can be more smoothly guided by the guide frame 4 and fall for collection, which not only simplifies the collection process, but also greatly improves the convenience and efficiency of collection.

[0035] See also Figure 2 , Figure 3 One end of the connecting rod 502 is rotatably connected to the push plate 302, and the other end of the connecting rod 502 is rotatably connected to the movable rod 501, ensuring that the push plate 302 is smooth and flexible when pushing the measured object, thereby protecting the measured object from damage during the screening process to the greatest extent. At the same time, the flexibility and stability of the entire limiting mechanism 5 are further enhanced. When the push plate 302 pushes the measured object, this connection method enables the movable rod 501 and the limiting plate 504 to be adaptively adjusted accordingly, ensuring effective limiting and guiding of the measured object, thereby greatly improving the screening efficiency and accuracy.

[0036] See also Figure 2 , Figure 3 The movable rod 501 is rotatably connected to one side of the conveyor belt 1 through the rotating shaft 503, so that the movable rod 501 and the limiting plate 504 can rotate smoothly and steadily under the push of the push plate 302, ensuring the stability and reliability of the movable rod 501 and the limiting plate 504 during the rotation process, and avoiding failure or damage caused by loose connection. At the same time, the movable rod 501 is rotatably connected to the conveyor belt 1 to ensure effective limiting and guiding of the measured objects, which not only improves the adaptability and flexibility of the screening device, but also makes the measured objects more stable and orderly during the transmission and screening process, thereby improving the screening efficiency and accuracy.

[0037] See also Figure 1There are multiple cylinders 301, and the multiple cylinders 301 are arranged equidistantly along the length line of the conveyor belt 1, which means that multiple push plates 302 can be simultaneously operated on the conveyor belt 1 to perform pushing operations, thereby improving the processing speed of the objects to be tested. The parallel operation of the multiple cylinders 301 makes the entire screening process more efficient and performs multi-stage screening operations. At the same time, the objects to be tested can be processed promptly and accurately on the entire conveyor belt. The design of equidistant linear arrangement not only optimizes space utilization, but also improves the overall working efficiency of the screening device.

[0038] See also Figure 1 , a plurality of guide frames 4 for guiding the measured objects are arranged on the other side of the conveyor belt 1, and the guide frames 4 are opposite to the push plate 302, and these guide frames 4 correspond to the positions of the measured objects, ensuring that the measured objects can accurately enter the guide frames 4 when being pushed, which helps to guide the measured objects to move along a predetermined path and prevent them from deviating from the direction or colliding with other objects during the conveying process. At the same time, since the guide frames 4 are opposite to the push plate 302, when the push plate 302 pushes the measured objects, the guide frames 4 can effectively receive and guide the measured objects, so that they can pass through the conveyor belt smoothly and fall into the predetermined collection position, which not only improves the collection accuracy of the measured objects, but also makes the entire screening and collection process more efficient and orderly. Embodiment 2:

[0039] See also Figure 1 , Figure 4 A visual inspection mechanism 6 for secondary inspection of the tested objects is arranged on the top side of the conveyor belt 1. The visual inspection mechanism 6 arranged on the top side of the conveyor belt 1 can perform secondary inspection on the tested objects, which means that before the objects are pushed and collected, the visual inspection mechanism can check the quality, quantity or other relevant characteristics of the objects again to ensure the accuracy and reliability of the screening process. At the same time, the existence of the visual inspection mechanism 6 improves the overall functionality of the screening device. In addition to the basic screening and collection functions, the mechanism can also provide real-time detection data to help operators better monitor and manage the screening process.

[0040] See also Figure 1 , Figure 4The visual inspection mechanism 6 includes a support frame 601, and an industrial camera 602 is arranged on the inner side of the support frame 601. The industrial camera 602 is vertically opposite to the conveyor belt 1. By setting the support frame 601, the visual inspection mechanism 6 can be firmly installed on the top side of the conveyor belt 1, ensuring the stability and safety of the industrial camera 602 during the inspection process. At the same time, the layout of the industrial camera 602 vertically opposite to the conveyor belt 1 enables the camera to directly capture the image of the inspected object from above, thereby obtaining clear and accurate visual information. This layout not only simplifies the inspection process, but also improves the accuracy and efficiency of the inspection, providing strong support for production quality control.

[0041] See also Figure 1 A control panel 2 is provided on the outside of the conveyor belt 1. The control panel 2 is used to control the conveyor belt 1 and the cylinder 301. The control panel 2 enables the operator to conveniently control the conveyor belt 1 and the cylinder 301 in real time. As a human-computer interaction interface, the control panel 2 provides an intuitive and concise operation interface, which reduces the difficulty of operation. At the same time, the integration of the control panel 2 improves the control efficiency and response speed of the entire screening device. Through the control panel 2, the operator can quickly adjust the running speed of the conveyor belt 1 and the action parameters of the cylinder 301 to meet the needs of different screening tasks.

[0042] See also Figure 1 , Figure 2 , Figure 3 The movable rod 501, the connecting rod 502, and the limit plate 504 are all made of stainless steel. The material selection of stainless steel ensures the structural strength and stability of these components during the operation of the screening device. Stainless steel, as a high-strength, corrosion-resistant material, can withstand greater mechanical stress and external impact, thereby extending the service life of the components. At the same time, stainless steel also has good anti-rust and anti-corrosion properties. In a humid or corrosive environment, stainless steel can resist rust and corrosion, keeping the surface of the components smooth and the performance stable.

[0043] The implementation principle of the utility model is as follows: first, the measured object is placed at the end position of the conveyor belt 1, and the conveyor belt 1 is used to transport the measured object. At the same time, the weighing sensor on the inner side of the conveyor belt 1 is used to weigh and measure the measured object. The obtained data transmits the signal to the corresponding cylinder 301 through the control panel 2. When the measured object is moved to an appropriate position by the conveyor belt 1, the corresponding cylinder 301 pushes the measured object through the push plate 302. At this time, the push plate 302 gradually pushes the measured object. Through the connection relationship of the connecting rod 502, it is conducive to promoting the movable rod 501 and the limit plate 504 to rotate to one side of the conveyor belt 1 until the limit plate 504 is placed parallel to the conveyor belt 1, and the measured object on one side is limited and blocked. At this time, when the measured object is pushed, the friction factor between the conveyor belt 1 and the measured object can be ignored, causing the measured object to move in a straight line, and the measured object is collected by falling through the guide frame 4, which is conducive to improving the convenience of collecting the measured object.
