Description

Technical Field

[0001] This utility model relates to the technical field of weighing and dispensing equipment, specifically to a lifting vibration device for a vertical powder weighing machine. Background Technology

[0002] A vertical powder weighing machine is a specialized device for quantitative weighing and dispensing of powdered materials. It mainly consists of a material hopper for storing the powder and a receiving mechanism. The weight of the discharged material is controlled by the discharge port at the bottom of the hopper in conjunction with the weighing device within the receiving structure, thus achieving weighing and dispensing. For example, the utility model patent with publication number CN221394172U provides a novel vertical powder weighing machine. Existing vertical powder weighing machines typically use a cylinder to drive a vibrating mechanism for lifting and lowering. When the vibrating mechanism rises and lifts the material cup, the powder inside the cup is vibrated. However, in actual production, it has been found that the cylinder is prone to damage during frequent extension and retraction, typically requiring replacement every three months. This affects the stability and reliability of the equipment, and also increases the frequency and cost of subsequent maintenance. Utility Model Content

Detailed Implementation

[0019] The present invention will be further described below through specific embodiments.

[0020] like Figures 1 to 3 As shown, the present invention provides a lifting vibration device for a vertical powder weighing machine, comprising a track plate 1, a lifting drive motor 2, a vibration mechanism 3, and a motion conversion transmission mechanism 4. The lifting drive motor 2 is mounted on the track plate 1 and drives the vibration mechanism 3 to lift and lower via the motion conversion transmission mechanism 4. The motion conversion transmission mechanism 4 is used to convert the circular motion output by the lifting drive motor 2 into linear motion that drives the vibration mechanism 3 to lift and lower.

[0021] By using the lifting drive motor 2 and the motion conversion transmission mechanism 4 in combination, the vibration mechanism 3 can be driven to lift. Compared with a cylinder, the lifting drive motor 2 is less prone to damage during long-term use, which helps to improve the stability and reliability of the equipment operation. At the same time, it will also reduce the number of subsequent maintenance and maintenance costs.

[0022] The motion conversion transmission mechanism 4 includes a gear rack 41 and a gear 42. The gear 42 is fixedly mounted on the motor shaft of the lifting drive motor 2. The gear rack 41 is arranged vertically and a guide component 5 is provided between it and the track plate 1. The guide component 5 is used to guide the lifting and lowering of the gear rack 41. The gear 42 meshes with the gear rack 41 for transmission. The vibration mechanism 3 is located at the upper end of the gear rack 41. Thus, when the lifting drive motor 2 drives the gear 42 to rotate, the gear 42 meshes with the gear rack 41 for transmission, and at the same time, the guide component 5 provides guidance, thereby realizing the lifting and lowering of the gear rack 41.

[0023] The guide assembly 5 includes a matching guide wheel 51 and a guide groove 52. The left and right sides of the toothed rack 41 are provided with the guide groove 52 arranged vertically. The left and right sides of the toothed rack 41 are provided with a plurality of vertically spaced guide wheels 51. The guide wheels 51 are rotatably mounted on the track plate 1 and locked by the locking assembly 6. The guide wheels 51 are embedded in the guide groove 52 and the two roll in cooperation. In this way, the toothed rack 41 can play a good guiding role in lifting and lowering, effectively ensuring the stability and smoothness of the toothed rack 41 when lifting and lowering.

[0024] In addition, preferably, each of the left and right sides of the toothed rack 41 is provided with 2-3 vertically spaced guide wheels 51.

[0025] The locking assembly 6 includes a track shaft 61, a first locking nut 62, and a second locking nut 63. One end of the track shaft 61 passes through the track plate 1 and is locked in place by the first locking nut 62. Correspondingly, one end of the track shaft 61 is fixedly provided with a first locking shaft with an outer diameter smaller than its own. The outer circumferential surface of the first locking shaft is provided with a first external thread to facilitate threaded connection with the first locking nut 62. The guide wheel 51 is sleeved on the other end of the track shaft 61 and locked in place by the second locking nut 63. Correspondingly, the other end of the track shaft 61 is fixedly provided with a second locking shaft with an outer diameter smaller than its own. The outer circumferential surface of the second locking shaft is provided with a second external thread to facilitate threaded connection with the second locking nut 63. The guide wheel 51 is a bearing, which can effectively ensure its smooth rotation.

[0026] The vibration mechanism 3 includes a vibrator 31, a vibrating top block 32, an upper fixed plate 33, a lower fixed plate 34, and an elastic component 35. The lower fixed plate 34 is fixedly installed on the upper end of the toothed rack 41. The upper fixed plate 33 is located above the lower fixed plate 34 and is elastically connected to the lower fixed plate 34 through the elastic component 35. There is at least one vibrating top block 32, which is fixedly installed on the upper end of the upper fixed plate 33. The vibrator 31 is located on one side of the upper fixed plate 33 and is fixedly connected to the upper fixed plate 33. Accordingly, the vibrator 31 can adopt the structure in the prior art. It vibrates by means of vibration, and with the elastic connection provided by the elastic component 35, it can drive the vibrating top block 32 to vibrate together.

[0027] The elastic components 35 are two and spaced apart. Each elastic component 35 includes a compression spring 351, a connecting bolt 352, and a connecting nut 353. The connecting bolt 352 passes through the upper fixing plate 33 and the lower fixing plate 34 in sequence and is threadedly connected to the connecting nut 353. The compression spring 351 is sleeved on the connecting bolt 352 and is located between the upper fixing plate 33 and the lower fixing plate 34. Preferably, the upper fixing plate 33 is a right-angle bent plate.

[0028] In addition, the lifting vibration device also includes a proximity switch 7, which is fixedly installed on the mounting plate 8, and the mounting plate 8 is fixedly installed on the track plate 1. The proximity switch 7 is used to limit the travel of the toothed rack 41 as it descends. Correspondingly, the toothed rack 41 is made of metal and can sense the proximity switch 7, thereby ensuring that the toothed rack 41 descends accurately into place, that is, ensuring that the vibration mechanism 3 descends accurately into place.

[0029] Preferably, the lifting drive motor 2 is a stepper motor.

[0030] In addition, the lifting drive motor 2 is fixedly installed on the motor plate 9, and the motor plate 9 is fixedly installed on the track plate 1 to facilitate the smooth installation of the lifting drive motor 2 on the track plate 1.

[0031] The above are only some specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
