Technical Field

[0001] This utility model relates to a linear vibrator, and more specifically, to a reciprocating linear vibrator. Background Technology

[0002] A linear vibrator is a mechanical device that uses the principle of vibration to achieve functions such as material conveying, screening, and compaction. It is widely used in food processing, building materials, chemical industry and other fields.

[0003] Most existing linear vibrators utilize a vibrating motor. The centrifugal force generated by the rotation of the eccentric block of the vibrating motor is converted into linear vibration by the vibrator. Through spring buffering and support, the material rolls, jumps, or slides within the machine body to achieve the function of material transportation. However, this type of linear vibrator is only suitable for vibration of linear material tracks, with a limited scope of application and high cost.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a reciprocating linear vibrator.

[0006] The technical solution of this utility model is:

[0007] A reciprocating linear vibrator includes a base and two vibrating elements disposed on the top of the base for fixing a material tray. The two vibrating elements are centrally symmetrically arranged. The top of the base is provided with four mounting seats, which are respectively located on both sides of the two vibrating elements. Both sides of the vibrating elements are fixedly connected to the mounting seats by a number of spring plates, and the spring plates on the same side of adjacent vibrating elements are staggered. A driving assembly for driving the vibrating elements to vibrate is provided at the bottom of the two adjacent vibrating elements. The driving assembly includes an electromagnet and a mating part, and there is a gap between the electromagnet and the mating part.

[0008] The present invention is further configured such that a fixing part is integrally formed at the bottom of the vibrating element, the electromagnet is connected to the fixing part of one vibrating element through a fixing block, and the mating part is connected to the fixing part of another vibrating element.

[0009] The present invention is further configured such that the fixing part has an inclined surface on the side facing the mounting base, and the top of the mounting base is correspondingly inclined and the distance between the top of the mounting base and the inclined surface is greater than the amplitude of the electromagnet.

[0010] The present invention is further configured such that the two opposite sides of the vibrating element are detachably connected to a fixing member, and the fixing member is positioned by inserting a positioning protrusion into a positioning recess on the vibrating element.

Detailed Implementation

[0022] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0023] Example 1: A reciprocating linear vibrator, such as... Figure 1 and Figure 2 As shown, the device includes a base 1, and two vibrating elements 2 for fixing a material tray are provided on the top of the base 1. The two vibrating elements 2 are arranged symmetrically at the center. The material tray is fixed on the top of the vibrating elements 2. Four mounting seats 3 are also fixedly connected to the top of the base 1. The four mounting seats 3 are respectively arranged on both sides of the vibrating elements 2. The mounting seats 3 are fixedly connected to the vibrating elements 2 by a number of spring plates 4. The spring plates 4 on the same side of adjacent vibrating elements 2 are staggered. The number of spring plates 4 is set to four and they are stacked on top of each other. Because the spring plates 4 on the same side of adjacent vibrating elements 2 are staggered, the material trays located on the top of the two vibrating elements 2 vibrate in opposite directions during vibration.

[0024] A drive assembly for driving the vibration of both vibrating elements 2 is located at the bottom of the two vibrating elements 2. The drive assembly includes an electromagnet 5 and a mating part 51. The mating part 51 is an armature. The bottom of both vibrating elements 2 is integrally formed with a fixing part 21. A fixing block is provided on one side of the electromagnet 5 and is fixedly connected to the fixing part 21 at the bottom of one of the vibrating elements 2 by bolts. The mating part 51 is fixedly connected to the fixing part 21 at the bottom of the other vibrating element 2 by bolts. There is a gap between the mating part 51 and the vibrating element 2. The gap makes it easier for the electromagnet 5 to move when it is started. When the electromagnet 5 is started, it will attract the mating part 51, which will drive the vibrating element 2 to move. Due to the setting of the spring plate 4, it has a good reset effect, thus ensuring the vibration effect of the vibrating element 2.

[0025] The fixing part 21 has an inclined surface on the side facing the mounting base 3. The mounting base 3 is inclined in the direction away from the fixing part 21, and the distance between the fixing part 21 and the mounting base 3 is greater than the amplitude of the electromagnet 5, so as to avoid collision and affect the service life of the overall structure. The bottom of the base 1 has a countersunk hole, and the bottom of the mounting base 3 has a threaded hole, so that the mounting base 3...

[0026] A fixing member 6 is detachably connected to one side of the two vibrating components 2 that are opposite to each other. A positioning recess 22 is provided on the opposite side of the two vibrating components 2. A positioning protrusion 61 is integrally formed on the side of the fixing member 6 facing the vibrating component 2. The positioning protrusion 61 is inserted into the positioning recess 22. The two work together to achieve a good positioning effect. A threaded hole is provided on the inner bottom wall of the positioning recess 22. A through hole is provided on the positioning protrusion 61 that mates with the threaded hole. The bolt is fixedly connected to the positioning protrusion 61 through the through hole. The top surface of the fixing member 6 is located above the opposite component. The material tray is fixed on the top surface of the fixing member 6, so that there is a gap between the material tray and the top surface of the vibrating component 2, which further ensures the service life.

[0027] The spring plate 4 is fixedly connected to the mounting base 3 by the fastening bolt 7. Adjusting shims 8 are provided on both sides of the spring plate 4. The adjusting shims 8 are provided with oblong holes 81 for the fastening bolt 7 to pass through. By setting the adjusting shims 8, the oblong holes 81 allow the adjusting shims 8 to be finely adjusted along the length of the spring plate 4, thereby finely adjusting the vibration frequency of the spring plate 4 and thus adjusting the vibration frequency of the entire linear vibrator.

[0028] Working principle: Two vibrating elements 2 are arranged symmetrically at the center, and the spring plates 4 on the same side of adjacent vibrating elements 2 are staggered. During vibration, the material trays located at the top of the two vibrating elements 2 vibrate in opposite directions.

[0029] When reciprocating screening is required, the reciprocating material tray has an elliptical cross-section. The reciprocating material tray is divided into two parts and fixed to the top of two fixing parts 6 respectively. When started, because the spring plates 4 on the same side of the adjacent vibrating parts 2 are staggered, the material trays located on the top of the two vibrating parts 2 vibrate in opposite directions, thereby making the reciprocating material tray reciprocate and achieve the effect of screening and conveying materials. When linear conveying is required, it is only necessary to fix the linear material guide rail to the top of one of the fixing parts 6 and fix the counterweight block to the top of the other fixing part 6 to ensure the vibration balance of the whole linear vibrator, so that linear conveying can be carried out and the application range of the whole linear vibrator can be expanded.

[0030] Example 2 differs from Example 1 in that, as Figure 3 and Figure 4 As shown, the fixing member 6 is fixed to the top of the vibrating member 2 by bolts. The top of the vibrating member 2 has a mounting hole 23. The fixing member 6 has a through hole communicating with the mounting hole 23. The through hole is a countersunk hole. The bolt passes through the through hole and is threaded to the mounting hole 23. The material tray is fixed to the top of the fixing member 6.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
