Description

Technical Field

[0001] The invention relates to the field of color sorter auxiliary equipment, in particular to a cleaning device for a conveyor belt of a color sorter. Background Art

[0002] A color sorter is a device that uses photoelectric detection technology to separate particles of different colors from materials based on their optical properties. A color sorter typically uses a conveyor belt to transport materials. While it works well for large particles, it can sometimes adhere to the belt when conveying small particles or materials with a certain degree of moisture, such as sediment. Due to the belt's recirculating nature, these adhered particles can affect subsequent material transport, ultimately affecting the final color sorting results.

[0003] In order to solve this problem, the prior art discloses a method of fixing a cleaning brush on a mounting bracket of a conveyor belt for processing. However, when a conventional cleaning brush is cleaning, the belt is in a fixed circulating state, and the cleaning brush forms a relative linear motion state with the belt after installation. This will cause linear marks to appear on the surface of the belt brushed by the cleaning brush. These marks are formed due to the friction of the particles and the bending of the bristles caused by the shape of the brush body during cleaning. The cleaning state that does not change for a long time will cause some materials to continue to pass through this gap. Some particles that pass through the gap will pass normally, while some particles are small or have a certain humidity and are squeezed to adhere to the belt surface, thereby forming linear marks, which seriously affect the subsequent color sorting process. Summary of the Invention

[0029] The following describes the embodiments of the present invention through specific examples. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different viewpoints and applications without departing from the spirit of the present invention.

[0030] In order to solve the problem of particle adhesion in the prior art, a cleaning brush is fixed on the mounting bracket of the conveyor belt for processing. However, when a conventional cleaning brush is cleaning, the belt is in a fixed circulating state, and the cleaning brush forms a relative linear motion state with the belt after installation. This will cause linear marks to appear on the belt surface brushed by the cleaning brush. These marks are formed due to the friction of the particles and the bending of the bristles caused by the shape of the brush body during cleaning. The cleaning state that does not change for a long time will cause some materials to pass through this gap. Some particles that pass through the gap will pass normally, while some particles are small or have a certain humidity and are squeezed to adhere to the belt surface, thereby forming linear marks, which seriously affect the subsequent color sorting process.

[0031] To solve the above problem, please refer to Figures 1 to 10 , provides a cleaning device for a conveyor belt of a color sorter, including: a frame 10 and a driving mechanism 30 arranged at one end of the frame 10.

[0032] Specifically, a plurality of rotatable auxiliary rollers 13 are provided on the inner side of the frame 10, and the driving mechanism 30 is used to drive the belt 20 and the auxiliary roller 13 to rotate. A protrusion 131 is provided on the side surfaces of both ends of the auxiliary roller 13, and a plurality of groups of cleaning plates 14 and transverse plates 112 are provided in parallel inside the frame 10. The transverse plates 112 are fixed to the frame 10, and the two ends of the cleaning plates 14 are inserted into the movable grooves 114 opened on the inner wall of the frame 10. The transverse plates 112 and the cleaning plates 14 are connected by elastic members 145. The upper end surface of the cleaning plate 14 is in contact with the belt 20. When the auxiliary roller 13 rotates, the protrusion 131 hits the cleaning plate 14 to drive the cleaning plate 14 to clean along the lower end surface of the belt 20 in an undirected planar moving state.

[0033] The rotation of the belt 20 depends on the drive of the driving mechanism 30, and the rotation of the belt 20 will drive the material to be transported on the surface of the belt 20. After the transportation is completed, the lower part of the belt 20 will pass through the cleaning plate 14 for cleaning. Unlike the traditional cleaning method, this embodiment realizes the pushing function of the cleaning plate 14 through the collision between the protrusion 131 and the cleaning plate 14, thereby allowing the cleaning plate 14 to move. Since the cleaning plate 14 is in contact with the surface of the belt 20, a wiping effect is formed.

[0034] Since the connection of the cleaning plate 14 is carried out through the elastic member 145, and the protrusion 131 is fixed on the auxiliary roller 13 and rotates therewith, the pushed cleaning plate 14 will lose the pulling force and rebound after being pushed out a certain distance, and the elastic member 145 itself has a certain elastic recovery ability, which will form a state of elastic pulling and pushing of the cleaning plate 14. Due to the complexity of the display environment, this state will continue to decay and become irregular, which can ensure that the cleaning plate 14 produces an irregular cleaning state during the elastic rebound process. By cooperating with these cleaning plates 14 set on multiple auxiliary rollers 13, the problem of linear imprints on the cleaning plate 14 during the cleaning process can be avoided.

[0035] In one embodiment, see Figure 3 and Figure 5 A baffle 143 is provided on the upper end surface of the cleaning plate 14, and an elastic member 145 is vertically fixed between the baffle 143 and the horizontal plate 112. A slot 2 144 is opened on the side of the baffle 143 close to the horizontal plate 112. When the auxiliary roller 13 rotates to the bottom, the protrusion 131 is stuck in the slot 2 144.

[0036] A limitation is usually required here, namely that the distance between the notch of the second slot 144 and the corresponding central axis of the auxiliary roller 13 must be less than the distance between the central axis of the auxiliary roller 13 and the outermost side of the first protrusion 131, and at the same time, greater than the radius of the auxiliary roller 13. This arrangement ensures that the first protrusion 131 can always be inserted into the second slot 144 during the rotation of the auxiliary roller 13. In this way, it is ensured that each rotation of the auxiliary roller 13 can drive the cleaning plate 14 to generate a path displacement, and this path displacement forms an irregular periodic cleaning function of the cleaning plate 14.

[0037] In order to further improve the structure of the frame 10, please refer to Figures 1 to 4 The frame 10 includes two parallel side panels 11 , a transverse panel 112 is disposed between the two side panels 11 , and a movable groove 114 is formed on the surface of the side panels 11 .

[0038] The lateral position is limited by the two side plates 11 , and the movement grooves 114 for limiting the cleaning plate 14 are respectively opened on the inner side walls, so that the planar movement direction of the cleaning plate 14 can be limited.

[0039] In the above solution, the movement of the cleaning plate 14 is not restricted, which may affect the cleaning effect in the irregular state of rebound. To solve this problem, please refer to Figures 1 to 5 The two ends of the cleaning plate 14 are integrally formed with a second protrusion 146, which is inserted into the interior of the movable groove 114. The groove height of the movable groove 114 is equal to the thickness of the second protrusion 146, and the width of the second protrusion 146 is less than the slot width of the movable groove 114.

[0040] The moving groove 114 is used to limit the movement state of the protrusion 146. Since the groove height of the moving groove 114 is equal to the thickness of the protrusion 146, this can ensure that the cleaning plate 14 can only move on the current plane, thereby ensuring that during the working process, no matter what the displacement state of the cleaning plate 14 is, it can always adhere to the surface of the belt 20 to achieve the cleaning effect.

[0041] In the above technical solution, the adjustment function of the belt 20 is not reflected. In order to solve this problem, please refer to Figures 1 to 4The side plate 11 is in the shape of a channel steel, and an adjusting plate 12 is inserted into one end of the side plate 11. A mounting plate 111 is provided in the groove of the side plate 11, and a mounting plate 2 124 is provided at the end of the adjusting plate 12. The mounting plate 111 and the mounting plate 2 124 are fixed by bolts. A connecting groove 121 is provided at the other end of the adjusting plate 12, and the two end shafts of the main roller 21 on the inner side of the belt 20 are inserted into the connecting groove 121. A positioning piece 122 is provided on the side of the connecting groove 121 away from the main roller 21, and a connecting ring 123 fixed to the end shaft of the main roller 21 is provided at the end of the positioning piece 122.

[0042] There are usually two main rollers 21, which are respectively arranged on the inner side of the two ends of the belt 20. The structure usually includes a roller body and an axis structure installed at both ends of the roller body. The roller body is installed by fixing the axis structure. When driving, it is only necessary to control the end of one of the main rollers 21 to rotate. The power can be transmitted to the main roller 21 at the other end through the belt 20, thereby driving the belt 20 to circulate and realize the function of conveying materials.

[0043] In this embodiment, the length of the entire frame 10 is extended by inserting an adjustment plate 12, and this length can be adjusted according to the insertion length of the adjustment plate 12. Finally, the mounting plate 111 and the mounting plate 2 124 are fixed by screws, and reinforced and limited with nuts to ensure the stability of the structure. The side connecting groove 121 is used to install the main roller 21, and the position of the main roller 21 is limited by the positioning piece 122 installed on the side to prevent the main roller 21 from falling from the connecting groove 121. The positioning piece 122 is fixed on the side plate 11 to ensure the overall stability. When disassembly is required, the bolts fixing the side plate 11 are directly removed, and the entire main roller 21, the positioning piece 122 and the connecting ring 123 can be removed from the side plate 11.

[0044] During cleaning, a lot of particles will fall. In order to collect these particles, please refer to Figures 1 to 4 Specifically, a slot 113 is provided on the surface of the side panel 11 , a waste box 17 is inserted into the slot 113 , and the upper portion of the waste box 17 is open and is located below the cleaning plate 14 .

[0045] The waste box 17 is inserted into the side to receive the waste. The waste cleaned at the cleaning plate 14 will directly fall into the interior of the waste box 17 through the opening at the upper end of the waste box 17, thereby completing the collection. After a period of use, the waste box 17 can be directly pulled out from the side and the waste inside can be processed. In order to facilitate the operation of the waste box 17, a handle or other auxiliary part can be provided on the outer facade of the waste box 17 to facilitate the extraction.

[0046] In the above technical solution, in order to ensure the height of the operation, it is necessary to control the radius of each auxiliary roller 13 to be consistent with the main roller 21. However, this design solution will increase the cost, and the excessive width of the main roller 21 will also affect the design of the frame 10. In order to avoid this problem, please refer to the following for details. Figure 1 、 Figure 8 、 Figure 9 、 Figure 10 A tensioning roller 16 for adjusting the height of the belt 20 is provided between the side plates 11 , and the ends of several auxiliary rollers 13 rotate synchronously with the main roller 21 through a synchronous belt 15 .

[0047] The belt 20 is adjusted by the tensioning roller 16 to ensure that the lower end surface of the belt 20 can better contact the cleaning plate 14, and the upper end surface of the belt 20 can better contact the auxiliary roller 13. This design method can ensure the tensioning state of the entire belt 20, and at the same time ensure that the belt 20 and the cleaning plate 14 are always tightly fitted, and can avoid the cleaning plate 14 from causing cutting damage to the belt 20 due to the loose state.

[0048] In order to further improve the overall structure of the device, please refer to Figure 1 、 Figure 3 、 Figure 5 as well as Figure 7 A support assembly 40 is provided at the lower end of the frame 10. The support assembly 40 includes a support leg 41 and a connecting member 42. A fixing hole 422 is provided on the surface of the connecting member 42. A bolt is inserted into the fixing hole 422 to fix it to the end of the support leg 41. An arc groove 421 is provided at the lower end of the connecting member 42. A threaded hole 411 is provided on the surface of the support leg 41. The threaded hole 411 is located inside the arc groove 421.

[0049] During installation, first fix the connecting piece 42 to the support leg 41 through the fixing hole 422, and then fix the upper end of the connecting piece 42 to the lower end surface of the side panel 11, also through bolts and nuts. The arc groove 421 at the bottom can be adjusted in angle according to the inclination requirement of the belt 20. Since the fixing hole 422 is always set at the center position of the arc groove 421, it can be ensured that after the position of the fixing hole 422 is fixed, within a certain range of adjustment angles, no matter how the connecting piece 42 is rotated, the threaded hole 411 is always in the arc groove 421, thereby ensuring adjustability when the belt 20 needs to be tilted.

[0050] To further enhance the adjustment effect of the bottom support assembly 40, please refer to Figure 1 、 Figure 3 、 Figure 5 as well as Figure 7The lower end of the support leg 41 is in the shape of a channel steel, and a retractable support rod 431 is provided at the bottom, and the end of the support rod 431 is connected to the suction cup foot 43.

[0051] The overall length of the entire support leg 41 can be adjusted through the support rod 431. The support rod 431 and the support leg 41 can be fixed and adjusted by using threads, and the suction cup foot 43 at the bottom can ensure the stability of the overall structure after tilting.

[0052] To further enhance the cleaning effect of the belt 20, please refer to Figure 3 and Figure 4 Specifically, the upper end surface of the cleaning plate 14 is provided with a scraper 141 and a cleaning brush 142. The scraper 141 is located between the cleaning brush 142 and the horizontal plate 112. The scraper 141 is inclined and the end is blade-shaped. The blade-shaped end of the scraper 141 and the cleaning brush 142 are in contact with the surface of the belt 20.

[0053] The scraper 141 is used to scrape off the waste from the surface of the belt 20 , and then the cleaning brush 142 is used to perform a brushing operation, and the cleaned waste falls into the interior of the waste box 17 .

[0054] In addition, Figure 1 and Figure 5 As shown, the belt 20 is driven by two main rollers 21, and one of the main rollers 21 is driven by Figure 5 The driving mechanism 30 is driven by the driving mechanism 30, which is usually a simple motor, a transmission gear 211, and a transmission belt. The transmission gear 211 is installed at the end of one of the main rollers 21, and the transmission belt is used to synchronously drive the gear at the power end of the motor to drive the entire rotation. In this solution, a small gear (not shown in the figure) is also provided on the shaft of the main roller 21. The small gear is engaged with the shaft of the auxiliary roller 13 through a chain. The purpose of this is to ensure the synchronization of the rotation of the main roller 21 and the auxiliary roller 13.

[0055] Due to the design of the above structure, during operation, it is necessary to control one end of the feeding to move the belt 20 toward the scraper 141 after the feeding is completed. This can ensure that the rotation of the auxiliary roller 13 can stably pull the cleaning plate 14 to produce an irregular elastic cleaning state.

[0056] The above embodiments are intended only to illustrate the technical solutions of the present invention and are not intended to limit the same. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical concepts disclosed herein are intended to be covered by the claims of the present invention.
