Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging machinery, and in particular to a weighing hopper for hardware scales. Background Technology
[0002] The weighing hoppers of existing packaging machinery are mostly designed to accommodate conventional products such as candy, rice, and pills. To ensure that the product falls into the packaging machine more easily, the bottom of the weighing hopper is often designed in a triangular shape.
[0003] With rising labor costs, more and more companies are using machinery to complete repetitive tasks like sorting and packaging. Hardware components present several challenges: they are heavy, subject to strong impacts, and come in various shapes and sizes, including not only common screws and nuts but also long nails or bolts. Therefore, a specialized weighing hopper for hardware scales is needed to overcome the weight and impact of these components and to accommodate hardware of different lengths and shapes. Utility Model Content
[0004] The main purpose of this utility model is to provide a special weighing hopper for hardware scales that can overcome the large weight and impact of external hardware parts and can be adapted to hardware parts of different lengths and shapes.
[0005] This utility model proposes a weighing hopper for hardware scales, including a weighing hopper body, a support frame, a cover plate, a connecting rod, and a rotating connecting component;
[0006] The weighing hopper body is fixedly connected to the frame via the support frame. The rotating connector is rotatably connected to the support frame and one end is connected to the motor, which can drive the rotating connector to rotate via the motor.
[0007] The cover plate is rotatably connected to the weighing hopper body, and both sides of the cover plate are rotatably connected to the other end of the rotating connector through the connecting rod. The support force on the cover plate can be improved by providing the connecting rod on both sides.
[0008] The bottom of the weighing hopper body is close to a plane, and the bottom and inner side of the weighing hopper body are slightly inclined inward. By setting the weighing hopper body with a bottom close to a plane, the impact resistance of the cover plate can be improved. By setting the weighing hopper body with a bottom and inner side slightly inclined inward, the cover plate can be rotated more easily.
[0009] Preferably, the inclination angle of the bottom and inner side of the weighing hopper body is between 10° and 30°.
[0010] Preferably, it further includes a return spring, one end of which is connected to the rotating connector and the other end of which is connected to the support frame, so that the rotating connector can be reset by the return spring.
[0011] Preferably, the rotating connector is provided with a rotation limiting rod, and the support frame is provided with a rotation limiting groove. The rotation limiting rod and the rotation limiting groove cooperate to limit the rotatable angle of the rotating connector.
[0012] The beneficial effects of this utility model's special weighing hopper for hardware scales are:
[0013] 1. By setting the weighing hopper body with a bottom close to a flat surface, the impact resistance and load-bearing capacity of the cover plate can be improved.
[0014] 2. The weighing hopper body, with its bottom and inner sides slightly tilted inward, facilitates the rotation of the cover plate. Attached Figure Description

[0020] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation
[0021] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.
[0022] Reference Figures 1 to 4 An embodiment of the weighing hopper for hardware scales of this utility model is presented:
[0023] A weighing hopper for hardware scales includes a weighing hopper body 2, a support frame 1, a cover plate 3, a connecting rod 4, a return spring 6, and a rotating connecting piece 5.
[0024] The support frame 1 includes a base 11 and two L-shaped connecting frames 12. The two connecting frames 12 are respectively disposed on both sides of the base 11, with one end of each connecting frame 12 fixedly connected to the base 11. The base 11 has base connection holes, through which it is connected to the frame screws. The other end of the support frame 12 is fixedly connected to the weighing hopper body 2 by screws. Each connecting frame 12 has a rotation limit groove 121. A connecting support rod 13 is also provided between the two connecting frames 12 to increase structural strength.
[0025] The bottom of the weighing hopper body 2 is nearly flat, and the bottom and inner side of the weighing hopper body 2 are slightly inclined inward. The inclination angle of the bottom and inner side of the weighing hopper body 2 is between 10° and 30°. The cover plate 3 is rotatably connected to the bottom of the weighing hopper body 2. By setting the weighing hopper body 2 with a bottom that is nearly flat, the impact resistance of the cover plate 3 can be improved. By setting the weighing hopper body 2 with a bottom and inner side that are slightly inclined inward, the cover plate 3 can be easily rotated.
[0026] The rotating connector 5 is rotatably connected to the support frame 1, with one end connected to the motor. Both sides of the cover plate 3 are rotatably connected to the other end of the rotating connector 5 via connecting rods 4. The connecting rods 4 on both sides enhance the support force on the cover plate 3. The rotating connector 5 is equipped with a rotation limit rod 41, which, in conjunction with the rotation limit groove 121, limits the rotatable angle of the rotating connector 5. One end of the return spring 6 is connected to the rotating connector 5, and the other end is connected to the support frame 12. The return spring 6 drives the rotating connector 5 to return to its original position.
[0027] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the contents of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
