Description

Technical Field

[0001] This utility model relates to the technical field of weighing and feeding devices, specifically an integral load-bearing weighing and feeding device. Background Technology

[0002] Currently, in industrial applications requiring quantitative feeding, spiral structures such as screw feeders are used to convey raw materials while simultaneously calculating their weight. However, this method is unreliable when feeding smaller, less uniformly sized materials, as the gaps between particles are uncertain, easily leading to overfeeding or underfeeding, thus affecting the quantitative accuracy of the feeding. Furthermore, improving the accuracy requires periodic disassembly and inspection of the servo motor, which is inconvenient due to its multi-bolt mounting. Therefore, improvements to existing technology are necessary. Utility Model Content

[0003] The purpose of this invention is to provide an integral load-bearing weighing and feeding device that solves the problems of inaccurate weighing and inconvenience in disassembling the motor.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an integral load-bearing weighing and feeding device, comprising a mounting column, a weighing sleeve fixedly connected to the upper end of the mounting column, two symmetrically distributed weighing sensors fixedly connected to the outer side of the weighing sleeve, a feeding box fixedly connected to the outer side of the weighing sensors, a hopper fixedly installed at the upper end of the feeding box, a servo motor slidingly contacting the outer side of the feeding box, a disassembly and assembly mechanism provided on the outer side of the feeding box, a feeder fixedly installed on the outer side of the weighing sleeve, a male coupling fixedly connected to the outer side of the output shaft of the servo motor, and a spiral feeding rod installed inside the feeding box via bearings.

[0005] Preferably, the outer side of the feeding box is fitted with a top cover by spline bolts, and the top cover slides in contact with the hopper, thus protecting the hopper.

[0006] Preferably, a female coupling is fixedly connected to one end of the screw feed rod, and the male coupling is inserted into the female coupling, which can drive the screw feed rod to rotate.

[0007] Preferably, the disassembly and assembly mechanism includes a fixed base, a flip plate hinged to the outside of the fixed base, two symmetrically distributed mounting rods fixedly connected to the outside of the servo motor, a stop frame fixedly connected inside the flip plate, a hook slidably connected inside the stop frame, a push frame fixedly connected to the outside of the hook, and a spring provided on the outside of the hook's rod. The flip plate can drive the hook to flip.

[0008] Preferably, the mounting rod is in slidable contact with the feeding box, and the hook is slidably connected to the mounting rod. The hook can limit the servo motor through the mounting rod.

[0009] Preferably, the stop is hinged to the fixed base, and the pusher is slidably connected to both the flip plate and the stop, and the pusher can drive the hook to move.

[0010] Preferably, one end of the spring is fixedly connected to the stop frame, and the spring is fixedly connected to the push frame. The spring can support the push frame with its elastic force.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model, by adding a weighing sleeve, a weighing sensor, and a feeding box to the mounting column, allows for overall weighing of the entire component above the weighing sleeve and the material inside the hopper through the weighing sleeve and the weighing sensor during use, thereby effectively avoiding inaccurate weighing caused by different material gaps.

[0013] 2. This utility model adds a flip plate, hooks and push frame to the feeding box. During use, the flip plate can drive the hooks to hang on the outside of the mounting rod outside the servo motor, thus completing the installation of the servo motor. When disassembly is required, the hooks can be removed from the mounting rod to disassemble the servo motor, making it easier to disassemble and install the servo motor during maintenance.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 An integral load-bearing weighing and feeding device includes a mounting column 1, a weighing sleeve 2 fixedly connected to the upper end of the mounting column 1, two symmetrically distributed weighing sensors 3 fixedly connected to the outer side of the weighing sleeve 2, a feeding box 4 fixedly connected to the outer side of the weighing sensors 3, a hopper 5 fixedly installed at the upper end of the feeding box 4, a servo motor 7 slidingly contacting the outer side of the feeding box 4, a disassembly and assembly mechanism 8 provided on the outer side of the feeding box 4, a feeder 9 fixedly installed on the outer side of the weighing sleeve 2, a male coupling 10 fixedly connected to the outer side of the output shaft of the servo motor 7, and a spiral feeding rod 11 installed inside the feeding box 4 through bearings.

[0022] Please see Figure 1-5 The outer side of the feeding box 4 is fitted with a top cover 6 by spline bolts. The top cover 6 slides in contact with the hopper 5 and can protect the hopper 5. One end of the screw feed rod 11 is fixedly connected to a female coupling 12. The male coupling 10 is inserted into the female coupling 12. The female coupling 12 can drive the screw feed rod 11 to rotate.

[0023] Please see Figure 1-5The disassembly and assembly mechanism 8 includes a fixed base 81, a flip plate 82 hinged to the outside of the fixed base 81, two symmetrically distributed mounting rods 83 fixedly connected to the outside of the servo motor 7, a stop 84 fixedly connected inside the flip plate 82, a hook 85 slidably connected inside the stop 84, a pusher 86 fixedly connected to the outside of the hook 85, and a spring 87 provided on the outside of the hook 85. The flip plate 82 can drive the hook 85 to flip. The mounting rod 83 is in slidable contact with the feed box 4, and the hook 85 is slidably connected to the mounting rod 83. The hook 85 can limit the servo motor 7 through the mounting rod 83. The stop 84 is hinged to the fixed base 81, and the pusher 86 is slidably connected to both the flip plate 82 and the stop 84. The pusher 86 can drive the hook 85 to move. One end of the spring 87 is fixedly connected to the stop 84, and the spring 87 is fixedly connected to the pusher 86. The spring 87 can support the pusher 86 through its elastic force.

[0024] The specific implementation process of this utility model is as follows: When in use, the material is put into the inside of the hopper 5. After the material is put in, the weighing sensor 3 can weigh the material. At the same time, the weighing sleeve 2 can weigh all the components and materials above the weighing sleeve 2. When it is necessary to discharge the material, the servo motor 7 is started. The servo motor 7 drives the screw feed rod 11 to rotate through the male coupling 10 and the female coupling 12. The screw feed rod 11 can feed the material by rotating. During the feeding process, the reduced weight can be weighed through the weighing sleeve 2, so that the weighing of the material can be more accurate.

[0025] When the servo motor 7 needs to be disassembled and repaired, push the pusher 86. The pusher 86 drives the hook 85 to move and compresses the spring 87. When the hook 85 disengages from the mounting rod 83, the limit on the mounting rod 83 can be released. Then the servo motor 7 and the mounting rod 83 can be removed from the feed box 4 for repair.
