Description

Technical Field

[0001] The present application relates to the technical field of color sorters, and in particular to a background plate fixing device for a color sorter. Background Art

[0002] Color sorter is a device that uses photoelectric technology to automatically sort out particles of different colors from granular materials based on the difference in the optical properties of the materials. The working principle of the color sorter is that the selected materials are sent into the trough through the vibrator under the feed hopper. The trough is at an angle of 60° to the horizontal plane. The materials slide freely in the trough and gradually spread out. When the materials leave the trough and enter the sorting area, there are light sources, background plates and CCD sensors in the sorting area. The CCD observes the color of the selected materials to judge the quality of the materials, and then separates the materials through the rejection system to achieve the purpose of rejection. The CCD sensor installed in the sorting room compares the amount of reflected light and transparent light of the material detected by the CCD sensor with the reference light, identifies the particles of different colors by using the color difference between the selected material and the reference color, and drives the spray valve to reject the particles of different colors to achieve the purpose of sorting. Therefore, it is very important for a stable background device to provide a stable reference signal.

[0003] The color sorter will generate certain vibrations during operation. The existing color sorter usually has a split structure for mounting the background plate, light source and sensor, which results in certain differences in the amplitude of vibration of each component, and thus may cause errors in reflected light. The sensor is prone to rejecting good products as defective products, resulting in unnecessary waste. Therefore, in order to solve the above problems, the present application provides a color sorter background plate fixing device.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0006] The present application provides a color sorter background plate fixing device, comprising a housing, a color sorting module is arranged on the inner side of the housing, the color sorting module comprises a background plate, a light source plate and a CCD sensor, mounting plates are arranged on both sides of the color sorting module, and the background plate, light source plate and CCD sensor in the color sorting module can be detachably installed at a position between two mounting plates;

[0007] A plurality of high-damping rubber blocks are fixedly connected to the outer sides of the two mounting plates, and the high-damping rubber blocks on the same side are fixedly connected to the casing on the same side with bolts.

[0008] Preferably, the mounting plate is provided with concave holes at positions corresponding to the high-damping rubber blocks, and screws threadedly connected to the high-damping rubber blocks are arranged inside the concave holes.

[0009] Preferably, fixing frames are provided at positions on both sides of the two mounting plates corresponding to the background plate and the light source plate, and the fixing frames are fastened to the background plate and the light source plate by fastening bolts.

[0010] Preferably, a motor is fixedly connected to the outer wall of one of the two mounting plates by bolts, and the output shaft of the motor passes through the center position of the outer wall of the mounting plate and the fixing frame and is fixedly connected.

[0012] Preferably, sliders are welded on both sides of the sensor bracket, and slide rails are respectively welded on the inner wall of the mounting plate corresponding to the two sliders, and the sensor bracket is slidably connected to the inner side of the slide rails through the sliders.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] By arranging mounting plates with an integrated structure on both sides of the color sorting module, the background plate, light source plate and sensor are installed as a whole using the mounting plates, so that when subjected to vibration force, the vibration trends of various components are the same, thereby reducing the influence of various components on each other. Compared with the existing split installation structure, the rejection accuracy of the color sorter is effectively improved.

[0025] A plurality of high-damping rubber blocks 9 are fixedly connected to the outer sides of the two mounting plates 2, and the high-damping rubber blocks 9 on the same side are bolted and fixedly connected to the casing 1 on the same side. The high-damping rubber blocks 9 have a good filtering effect on vibration. On the one hand, the transmission of vibration to the mounting plate 2 of the color sorting module is reduced, and on the other hand, a good position fixing relationship between the mounting plate 2 and the casing 1 is ensured. The background plate 3, the light source plate 4 and the CCD sensor 6 in the color sorting module are installed on an integrated mounting plate 2, so that when the vibration is too large, the vibration force is transmitted to the color sorting module through the high-damping rubber blocks 9, and the vibration effect of the entire color sorting module is close, thereby reducing the deviation of the angles caused by the vibration force between the components, thereby reducing the possibility of misjudgment of the machine.

[0026] The mounting plate 2 is provided with recessed holes at positions corresponding to the high damping rubber blocks 9, and screws 10 threadedly connected to the high damping rubber blocks 9 are arranged on the inner sides of the recessed holes. The mounting plate 2 and the high damping rubber blocks 9 are fixed by means of the screws 10, so that there is a transition of the high damping rubber blocks 9 between the mounting plate 2 and the casing 1, thereby avoiding a hard connection between the mounting plate 2 and the casing 1, thereby reducing the effect of vibration force conduction. Fixing frames 11 are arranged at positions on both sides of the two mounting plates 2 corresponding to the background plate 3 and the light source board 4, and the fixing frames 11 are fastened to the background plate 3 and the light source board 4 by fastening bolts 12.

The motor 8 is bolted fixedly connected to the outer wall of one of the two mounting plates 2, and the output shaft of the motor 8 passes through the center position of the outer wall of the mounting plate 2 and the fixing frame 11 and is fixedly connected. A through hole for the motor 8 is opened on the casing 1 to avoid direct contact between the components on the mounting plate 2 and the casing 1, and the motor 8 is used to adjust the angles of the background plate 3 and the light source plate 4.

[0027] A sensor bracket 5 is arranged on the outer side of the CCD sensor 6, and the sensor bracket 5 and the mounting plate 2 are detachably connected, sliders 51 are welded on both sides of the sensor bracket 5, and two corresponding sliders 51 on the inner wall of the mounting plate 2 are respectively welded with slide rails 7, and the sensor bracket 5 is slidably connected to the inner side of the slide rail 7 through the slider 51, and the slider 51 and the slide rail 7 have a movable space for sliding in the direction of the mounting plate 2, for example: each slide rail 7 is two symmetrically arranged Z-shaped structures, and the slider 51 is two symmetrically arranged L-shaped structures.
