DETAILED DESCRIPTION
[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0026] Reference Figure 1 to Figure 2 The utility model discloses a direct vibration feeding mechanism, comprising: a linear guide rail 13, the bottom of the linear guide rail 13 is transmission-connected with an angle-adjustable vibration component, a step structure 14 is provided at the discharge end of the linear guide rail 13, and a spacer feeding component is provided at the step structure 14;
[0027] The spacer material transfer assembly includes a water trough 19, which is fixedly connected to the bottom of the step structure 14. A heavy stop block 17 and a light pressure block 18 are vertically slidably connected to the top of the water trough 19. The tops of the heavy stop block 17 and the light pressure block 18 are flush with the high end of the step structure 14, and the light pressure block 18 is arranged away from the high end of the step structure 14. The heavy stop block 17 and the light pressure block 18 are transmission connected. A limit portion is provided on one side of the heavy stop block 17, and the limit portion is arranged in the linear guide rail 13.
[0028] When in use, the water tank 19 is filled with water, and the top of the light pressure block 18 is flush with the top of the heavy block 17 under the action of buoyancy, and the top of the heavy block 17 is flush with the plane where the high end of the step structure 14 is located. When the material moves to the position of the step structure 14 along the linear guide rail 13, the material first moves to the top of the heavy block 17. At this time, the heavy block 17 does not move under the action of the limiter, and then moves to the top of the light pressure block 18 under the action of vibration. At this time, the material presses the light pressure block 18 downward under the action of gravity, and because the light pressure block 18 moves downward to squeeze the water in the water tank 19 to move toward the heavy block 17, the heavy block The increase in water volume under block 17 causes the heavy block 17 to be lifted up, so that the top of the heavy block 17 is higher than the plane where the conveying surface of the linear guide 13 is located, thereby preventing the material from continuing to move forward. When the current material continues to move and separates from the top of the light pressure block 18, the heavy block 17 moves downward under the action of gravity, and the buoyancy of the water will lift the light pressure block 18. The top of the heavy block 17 and the top of the light pressure block 18 return to the plane where the high end of the step structure 14 is located, so that the previously blocked material can continue to move. By setting up in this way, a gap is created between two adjacent materials to prevent multiple materials from entering the next process at the same time.
[0029] According to a further optimized solution, a wedge-shaped bar 20 is fixedly connected to the top of the heavy stopper 17 , and the lower end of the wedge-shaped bar 20 is arranged close to the high end of the step structure 14 .
[0030] The lower end of the wedge strip 20 is arranged close to the upper end of the step structure 14, so that the material needs to cross the wedge strip 20 under the action of vibration. When the first material crosses the wedge strip 20 and falls on the top of the light pressure block 18, the heavy block 17 will carry the wedge strip 20 up together, so that the next material will slide along the oblique edge of the wedge strip 20, thereby increasing the gap between the two adjacent materials. It is prevented that more than two materials fall on the light pressure block 18 at the same time, which affects the separation effect.
[0031] According to a further optimized solution, the limiting part includes a limiting groove 15 , which is provided in the linear guide rail 13 and is located on one side of the step structure 14 . A limiting plate 16 is provided in the limiting groove 15 , and the limiting plate 16 is fixedly connected to the side wall of the heavy stop block 17 .
[0032] Through the limiting cooperation between the limiting groove 15 and the limiting plate 16 , the top of the heavy stopper 17 can only move in the direction higher than the conveying surface of the linear guide rail 13 .
[0033] According to a further optimized solution, the angle-adjustable vibration component includes a shell 1 , and angle adjustment parts are respectively arranged at the four corners of the bottom of the shell 1 . A vibration part is arranged inside the shell 1 , and the vibration part is transmission-connected to the linear guide rail 13 .
[0034] According to a further optimized solution, the vibration part includes a vibration table 12, and the top of the vibration table 12 is fixedly connected to the bottom of the linear guide rail 13;
[0035] A counterweight is fixedly connected to the bottom center of the vibration table 12;
[0036] A mounting seat 2 is provided below the counterweight part, and the mounting seat 2 is fixedly connected to the inner wall of the bottom of the housing 1, and a gap is left between the bottom of the counterweight part and the top of the mounting seat 2;
[0037] Two elastic vibration parts are provided between the vibration table 12 and the mounting seat 2 . The two elastic vibration parts are centrally symmetrically arranged and are respectively located on both sides of the counterweight part.
[0038] Further optimized solution, the elastic vibration part includes an elastic sheet 7, the elastic sheet 7 is fixedly connected to one end of a connecting sheet 8, the other end of the connecting sheet 8 is fixedly connected to a rigid sheet 9, the top of the rigid sheet 9 of the elastic vibration part located on the left side is fixedly connected to the bottom of the vibration table 12, and the bottom of the elastic sheet 7 of the elastic vibration part located on the left side is fixedly connected to the top of the mounting seat 2;
[0039] The top of the elastic sheet 7 of the elastic vibration part on the right is fixedly connected to the bottom of the vibration table 12 , and the bottom of the rigid sheet 9 of the elastic vibration part on the right is fixedly connected to the top of the mounting seat 2 ; a piezoelectric ceramic 21 is fixedly connected to one side of the connecting sheet 8 .
[0040] According to a further optimized solution, the counterweight part includes a counterweight block 10 , which is fixed to the bottom center of the vibration table 12 , and a gap is provided between the bottom of the counterweight block 10 and the top of the mounting seat 2 .
[0041] Vibration is generated by energizing the piezoelectric ceramic 21. Since the two elastic sheets 7 are arranged symmetrically, the vibration direction of the vibration table 12 remains consistent, so that the material can only move along the linear guide 13 from the feed end to the discharge end. The counterweight 10 can effectively increase the vibration effect.
[0042] A further optimized solution is that the angle adjustment part includes a ball head 3, which is spherically hinged at the corner of the outer shell 1, and the center of the ball head 3 is vertically slidably connected to a threaded rod 4, the middle part of the threaded rod 4 is sleeved with a nut 6, the nut 6 is threadedly connected to the threaded rod 4, and the bottom of the threaded rod 4 is fixedly connected to a base plate 5.
[0043] By rotating the nut 6 and adjusting the vertical position of the nut 6 on the threaded rod 4, the height of each ball head 3 changes, and under the action of the spherical hinge between the housing 1 and the ball head 3, the housing 1 can be tilted at any angle, thereby driving the linear guide 13 to tilt.
[0044] According to a further optimized solution, the top of the housing 1 is coaxially fixed with the bottom of the sealing rubber ring 11 , and the top of the sealing rubber ring 11 is fixed to the bottom of the vibration table 12 .
[0045] The sealing rubber ring 11 disposed between the vibration table 12 and the housing 1 can prevent dust from entering the housing 1 on the one hand, and can prevent the vibration of the vibration table 12 from being transmitted to the housing 1 on the other hand, thereby achieving a shock-absorbing effect.
