Abstract
Description
Technical Field
[0001] This application relates to the technical field of conveyors with annular load conveying surfaces, i.e., belt or similar continuous components, where traction is transmitted by means of a device other than annular drive elements of similar shape, and more particularly to a conveyor device with a vibrator. Background Technology
[0002] Most quick-freezing machines are equipped with conveyor belts to transport products. During the operation of the quick-freezing machine, the products will carry moisture with them when they enter the freezing tunnel. Once inside the freezing tunnel, the products will freeze together under the action of the water, causing two or more products to stick together.
[0003] To address the aforementioned issues, document CN111422551A discloses a conveyor belt structure with a vibrator. By installing a vibrating motor at the bottom of the conveyor belt, the vibrating rod is driven to vibrate, thereby causing the conveyor belt to vibrate during operation. This vibration method breaks down frozen products into individual units for freezing, ensuring the quality of the frozen products.
[0004] However, during the quick-freezing process, the required vibration amplitude varies depending on the moisture content, surface smoothness or roughness, and weight of the frozen items. In the early stage of quick-freezing, the surface of the items begins to freeze, and the risk of sticking is high but easy to handle. In the middle stage of quick-freezing, the ice layer thickens, increasing the adhesion strength. In the later stage of quick-freezing, the items are completely frozen, and the risk of sticking decreases. For example, porous items (such as bread) freeze faster and may require a larger amplitude in the early stage, while dense items (such as steak) freeze slower, and the risk of sticking is highest in the middle stage.
[0005] Therefore, there is an urgent need for a conveyor belt that can adjust the vibration amplitude at different positions of the conveyor belt. Utility Model Content
[0006] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes:
[0007] A vibrating conveyor includes a frame and a conveyor belt mounted on the frame. The conveyor belt has a conveying surface for receiving items. The frame is provided with a plurality of vibration mechanisms spaced apart along its length. Each vibration mechanism includes a drive element, a rotating shaft, and an eccentric shaft. The rotating shaft is horizontally and rotatably mounted on the frame and distributed below the conveying surface. Mounting brackets are mounted at both ends of the rotating shaft. Adjustment mechanisms are provided on the two mounting brackets. The eccentric shaft is horizontally disposed between the two mounting brackets and connected to the adjustment mechanisms. The drive element is mounted on the frame and is drively connected to the rotating shaft, and is used to drive the rotating shaft to rotate.
[0008] The technical solution adopted by one embodiment of this utility model to solve its technical problem is as follows: the adjustment mechanism includes a screw and a slider, the mounting bracket is provided with strip holes distributed radially along the rotating shaft, the screw is arranged radially in the strip holes along the rotating shaft, and its two ends are respectively mounted in the strip holes through bearings that rotate with it, the slider is threaded on the screw, and the two ends of the eccentric shaft are respectively connected to the sliders on the two mounting brackets.

[0010] The technical solution adopted by one embodiment of this utility model to solve its technical problem is as follows: multiple eccentric shafts are provided, and the multiple eccentric shafts are arranged at intervals along the circumference of the rotating shaft and are respectively connected to the mounting bracket through the adjustment mechanism.
[0011] The technical solution adopted by one embodiment of this utility model to solve its technical problem is as follows: the eccentric shaft includes a shaft body and a wheel body. The two ends of the shaft body are respectively connected to the mounting bracket through the adjustment mechanism.

[0012] The beneficial effects of this utility model are as follows: The adjustment mechanism can be used to adjust the distance between the eccentric shaft and the rotating shaft, thereby adjusting the distance between the eccentric shaft and the conveying surface. When the driving component drives the rotating shaft to rotate the eccentric shaft, the vibration amplitude of the eccentric shaft on the conveying surface is adjusted, which is more intuitive and easier to adjust.

[0022] Reference Figure 1-4This application proposes an embodiment of a vibrating conveyor device, which includes a frame 10 and a conveyor belt mounted on the frame 10. The conveyor belt has a conveying surface 20 for receiving items. The frame 10 is provided with a plurality of vibration mechanisms at intervals along its length. Each vibration mechanism includes a drive member 30, a rotating shaft 40, and an eccentric shaft 50. The rotating shaft 40 is horizontally rotatably mounted on the frame 10 and distributed below the conveying surface 20. Mounting brackets 60 are respectively mounted at both ends of the rotating shaft 40. Adjustment mechanisms 70 are respectively provided on the two mounting brackets 60. The eccentric shaft 50 is horizontally arranged between the two mounting brackets 60 and is respectively connected to the adjustment mechanisms 70. The drive member 30 is mounted on the frame 10 and is connected to the rotating shaft 40 for transmission, and is used to drive the rotating shaft 40 to rotate.
[0023] The adjustment mechanism 70 can be used to adjust the distance between the eccentric shaft 50 and the rotating shaft 40, thereby adjusting the distance between the eccentric shaft 50 and the conveying surface 20. When the driving member 30 drives the rotating shaft 40 to rotate the eccentric shaft 50, the vibration amplitude of the eccentric shaft 50 on the conveying surface 20 is adjusted, which is more intuitive and easier to adjust. For vibration mechanisms at different positions on the conveyor belt, the distance between the eccentric shaft 50 and the rotating shaft 40 on the vibration mechanisms at different positions can be adjusted separately, making it more convenient to use.
[0024] Specifically, the adjustment mechanism 70 includes a screw 71 and a slider 72. The mounting bracket 60 has strip-shaped holes 61 radially distributed along the rotating shaft 40. The screw 71 is radially disposed within the strip-shaped holes 61 along the rotating shaft 40, and its two ends are respectively mounted within the strip-shaped holes 61 via bearings that rotatably engage with it. The slider 72 is threaded onto the screw 71. Both ends of the eccentric shaft 50 are respectively connected to the sliders 72 on the two mounting brackets 60. When adjusting the vibration amplitude of the vibration mechanism, rotating the screw 71 causes it to rotate and drive the slider 72 to move radially along the rotating shaft 40 within the strip-shaped holes 61, thereby adjusting the position of the eccentric shaft 50 and thus adjusting the vibration amplitude of the vibration mechanism. The slider 72 is disposed within the strip-shaped holes 61 and engages with the hole wall of the strip-shaped holes 61, preventing the slider 72 from rotating with the screw 71.
[0025] The adjusting mechanism 70 further includes a helical gear 73. The mounting bracket 60 is provided with a through hole 62 corresponding to the strip hole 61. The screw 71 extends into the through hole 62. The helical gear 73 is disposed in the through hole 62 and sleeved on the screw 71 and connected and fixed thereto. A rotating wheel 80 is mounted on the mounting bracket 60, and the rotating wheel 80 is provided with teeth that mesh with the helical gear 73.
[0026] When adjusting the position of slider 72, the rotating wheel 80 is rotated. The rotating wheel 80 drives the helical gear 73 to rotate through the teeth. The helical gear 73 drives the screw 71 to rotate. The rotation of the screw 71 drives the slider 72 to move along the axial direction of the screw 71, thereby adjusting the radial distance between the eccentric shaft 50 and the rotating shaft 40. The operation is convenient and can meet the needs of different vibration amplitudes.
[0027] Furthermore, multiple eccentric shafts 50 are provided, and the multiple eccentric shafts 50 are arranged at intervals along the circumference of the rotating shaft 40 and are respectively connected to the mounting bracket 60 through the adjusting mechanism 70.
[0028] Referring to the accompanying drawings, when the rotating shaft 40 drives the eccentric shaft 50 to rotate, each rotation of the rotating shaft 40 causes the conveying surface 20 of the conveyor belt to vibrate. At this time, the rotating wheel 80 can synchronously drive the multiple helical gears 73 to rotate, thereby adjusting the radial distance between the multiple eccentric shafts 50 and the rotating shaft 40, making it more convenient to use.
[0029] Preferably, the eccentric shaft 50 includes a shaft body 51 and a wheel body 52. The two ends of the shaft body 51 are respectively connected to the mounting bracket 60 through the adjusting mechanism 70. The two ends of the wheel body 52 are respectively rotatably mounted on the shaft body 51 through bearings. When the wheel body 52 is in contact with the conveying surface 20, the wheel body 52 can rotate relative to the conveying surface 20, thereby reducing the wear of the wheel body 52 by the conveying surface 20.
[0030] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
