Description

Technical Field

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

[0002] Silk is a textile made from silkworm silk or synthetic fibers, man-made fibers, filaments, etc.; it is a general term for fabrics made purely or interwoven from silkworm silk or rayon. In ancient times, silk referred specifically to textiles woven from silkworm silk (mainly mulberry silk, but also including small amounts of tussah silk and cassava silk). After raw silk materials are packed, the weight of each individual box needs to be weighed for management. Some raw silk materials are often packaged in boxes with metal edging, such as some high-end packaging or boxes used for long-distance sea freight, to increase the strength of the box.

[0003] In Chinese utility model patents, such as CN222104866U, a mobile continuous weighing device is disclosed, which relates to the field of continuous weighing technology. When in use, it can play a role in continuous weighing, avoiding the need for manual handling of goods onto the scale for weighing, and reducing the labor intensity of manual labor.

[0004] In the above technology, the boxes are pushed to the top of the support plate in sequence and weighed by pressure sensors. However, when weighing boxes with metal edging, the metal edging will cause wear to the support plate, thus affecting the accuracy of the detection. In addition, debris and other impurities will be generated when the boxes are moved and accumulate on the support plate. Therefore, a continuous weighing device is needed to address the above problems. Utility Model Content

[0029] This utility model provides a technical solution:

[0030] Reference Figure 1-5 A continuous weighing device includes a conveyor frame 1, two conveyor belts 3 are symmetrically installed on the top surface of the conveyor frame 1, a weighing component 4 is installed on the top surface of the conveyor frame 1 and the weighing component 4 is located between the two conveyor belts 3, the weighing component 4 includes a fixed frame 41, a plurality of pressure sensors 42 are installed on the top surface of the fixed frame 41, a weighing frame 43 is installed on the top surface of the plurality of pressure sensors 42, a plurality of rotating shafts 44 are rotatably connected to the weighing frame 43, a first bracket 7 and a second bracket 8 are fixedly installed on the top surface of the conveyor frame 1 respectively, an intermittent feeding component 5 is provided on the bottom surface of the first bracket 7, a cleaning component 6 is provided on the bottom surface of the second bracket 8, the cleaning component 6 includes a lead screw sleeve 63 and the lead screw sleeve 63 is slidably connected to the bottom surface of the second bracket 8, and a cleaning brush 64 is installed on the bottom surface of the lead screw sleeve 63;

[0031] By using multiple rotating shafts 44, the static friction of moving the box onto the weighing assembly 4 is changed to dynamic friction, which can reduce the wear of the box being conveyed onto the weighing frame 43, thereby ensuring the detection accuracy of the pressure sensor 42. Furthermore, the cleaning brush 64 can clean the debris and other impurities remaining on the weighing frame 43, further ensuring the detection accuracy of the pressure sensor 42. The rotation of the conveyor belt 3 is driven by an external drive source.

[0032] Furthermore, the cleaning assembly 6 also includes a reciprocating screw 62, which is rotatably connected to the inner side of the second bracket 8 and threadedly connected to the screw sleeve 63, thereby driving the screw sleeve 63 to perform linear reciprocating motion.

[0033] Furthermore, the cleaning component 6 also includes two slots 67, which are respectively opened on the inner sides of the two second brackets 8. Each slot 67 is equipped with an elastic block 66, and a collection box 65 is fixedly installed on the outer side of each elastic block 66. The collection box 65 is secured in the slot 67 by the elastic block 66, and its own deformation ensures the installation stability of the collection box 65 and facilitates disassembly. The collection box 65 collects the debris and other debris that are cleaned up.

[0034] Furthermore, the intermittent feeding assembly 5 includes a rotating plate 51, which is rotatably connected to the two inner sides of the first bracket 7. An electric push rod 52 is fixedly installed on the outer side of the rotating plate 51, and a protective pad 53 is installed at the other end of the electric push rod 52. Multiple magnetic components 54 are installed on the other side of the rotating plate 51. Two magnetic sleeves 55 are symmetrically installed on the bottom surface of the first bracket 7. An electromagnet 56 is installed in each magnetic sleeve 55. By intermittently supplying power to the electromagnet 56, the magnetic components 54 can be attracted to the magnetic sleeve 55, thereby allowing the rotating plate 51 to rotate freely or be limited.

[0035] Furthermore, the bottom surface of the second bracket 8 is provided with a sliding groove 61, and the lead screw sleeve 63 is slidably connected in the sliding groove 61. The sliding groove 61 limits the lead screw sleeve 63 so that it cannot rotate and can only slide linearly.

[0036] Furthermore, a controller 2 is fixedly installed on the outer side of the conveyor frame 1, and a drive motor 68 is fixedly installed on the outer side of the second bracket 8, and the output shaft of the drive motor 68 is connected to the reciprocating lead screw 62.

[0037] In practical use, the working principle of this utility model is as follows:

[0038] In this utility model, when the device is used: First, the operator places the box gap on the conveyor belt 3, and the conveyor belt 3 drives the box to move sequentially to the position of the first support 7. At this time, the electromagnet 56 is de-energized, and the magnetic component 54 does not attract the magnetic sleeve 55. After the box moves and comes into contact with the rotating plate 51, the friction between the conveyor belt 3 and the box can push the rotating plate 51 to rotate outward. Then, after the box passes the rotating plate 51, the rotating plate 51 resets under the action of gravity. At this time, the electromagnet 56 is powered, and the magnetic sleeve 55 becomes magnetic and attracts the magnetic component 54 to the magnetic sleeve 55, thereby limiting the rotating plate 51 so that it cannot rotate, which is convenient for blocking the subsequent box.

[0039] Next, the box moves to the end of the conveyor belt 3, and under the action of inertia, part of the box moves to the top surface of the rotating shaft 44. At this time, the electric push rod 52 can be started to drive the protective pad 53 to push the box, and move the box completely to the top surface of the rotating shaft 44. Then, the pressure sensor 42 accurately weighs the box. After that, the electric push rod 52 is used to retract and drive the protective pad 53 to move the box to another conveyor belt 3, so that the box continues to be conveyed. At the same time, the drive motor 68 can be started to drive the reciprocating screw 62 to rotate, thereby pushing the screw sleeve 63 to slide, so that the screw sleeve 63 completes the reciprocating sliding. The cleaning brush 64 pushes the debris and other impurities on the top surface of the weighing frame 43 into the collection box 65. Then, the cleaning brush 64 is reset to complete the cleaning of the weighing frame 43.

[0040] Then the subsequent boxes are moved to the position of the first support 7, and the above operation is repeated to complete the continuous weighing of multiple boxes.

[0041] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
