Description

Technical Field

[0001] The utility model relates to the technical field of color sorter feeding, in particular to a material jumping prevention device for a color sorter. Background Art

[0002] A color sorter is a device that uses photoelectric detection technology to automatically sort out bad materials from granular materials based on differences in their optical properties. It is used for bulk materials, packaged industrial products, and food quality testing and grading. The waterfall color sorter is a widely used type of color sorter. A conveyor belt mounted on top of the color sorter drives the material. The material that falls onto the belt is transported to the color sorter for sorting.

[0003] During the unloading and conveying process, materials are prone to jumping and uneven accumulation, which can easily lead to reduced color sorting accuracy and material splashing. For example, a color sorter anti-jumping device with authorization announcement number "CN221387602U" is equipped with an anti-jumping plate bracket and an anti-jumping plate. This device can effectively prevent material jumping and improve color sorting efficiency and accuracy. Although the anti-jumping plate can flatten the material on the conveyor belt and convey it evenly to prevent material accumulation and jumping, the anti-jumping plate will scrape the material flat for a long time, causing a large amount of excess material to be intercepted on one side of the anti-jumping plate. If these materials are not cleaned up in time, they will accumulate, which is not conducive to the smooth transportation of materials on the conveyor belt. Utility Model Content

[0004] The purpose of the utility model is to provide a material jumping prevention device for a color sorter to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A material jumping prevention device for a color sorter includes a conveyor, wherein the conveyor includes two baffles, two conveying rollers rotate between the two baffles, and a conveyor belt is connected between the two conveying rollers. The device also includes:

[0007] Two anti-jumping mechanisms are both rotatably arranged on the top of the conveyor belt. The anti-jumping mechanism includes a support seat 1 and a support seat 2 that are slidably connected to the baffle. An arc-shaped plate rotates between the support seat 1 and the support seat 2. A circular plate is fixed to one end of the arc-shaped plate. A shaft is rotatably provided in the middle of the circular plate. An auger is fixed to the outside of the shaft.

[0008] Two driving mechanisms, both fixed on the outside of a baffle, are used to drive the auger to rotate and transport the intercepted excess material;

[0009] Two adjustment mechanisms are arranged above the anti-jumping mechanism at corresponding positions to adjust the distance between the curved plate and the conveyor belt to accommodate the passage of materials of various specifications.

[0010] Furthermore, a connecting plate is fixed between one ends of the two baffles, a material receiving plate is fixed between one ends of the two baffles, and a supporting plate is fixed between the two baffles.

[0011] Furthermore, one edge of the arc-shaped plate is set as an inclined surface, and a rotating ring rotatably connected to the second support seat is fixed at one end of the arc-shaped plate.

[0012] Furthermore, a notch for rotatably connecting with the circular plate is formed on one side of the first support seat, a discharge hole is formed through one side of the second support seat, and a discharge plate fixed to the second support seat is arranged outside the discharge hole.

[0013] Furthermore, two brackets are fixed to the outside of one of the baffles, and a collecting box is placed inside the brackets.

[0014] Furthermore, the driving mechanism includes:

[0015] A first motor, fixedly connected to the baffle, and a gear is fixed to the output end of the first motor;

[0016] A toothed ring, meshed and driven with the gear, a transmission wheel rotatably connected to the first support seat is fixed to the inner ring side of the toothed ring, the transmission wheel is fixedly connected to the circular plate, and the shaft rod rotatably penetrates through the transmission wheel;

[0017] A second motor, the output end of which is fixedly connected to the shaft rod, and a U-shaped frame rotatably connected to the shaft rod is fixed to one end of the second motor, and the U-shaped frame is fixedly connected to the first support seat.

[0018] Furthermore, the adjusting mechanism includes:

[0019] Two U-shaped seats, which are fixedly connected to the baffle;

[0020] Two screw rods, respectively screwed and connected to the U-shaped seats at corresponding positions;

[0021] A cross beam, rotatably connected to the bottom ends of the two screw rods, and the bottom surface of the cross beam is fixedly connected to the first support seat and the second support seat.

[0022] Compared with the prior art, the beneficial effects of the present utility model are:

[0023] 1. By arranging the arc-shaped plate above the conveyor belt, the arc-shaped plate can intercept the materials accumulated on the surface of the conveyor belt on one side of the scraper, prevent the materials from accumulating during transportation and jumping, and improve the color sorting accuracy.

[0024] 2. By rotating the screw rod forward and backward to make the cross beam adjust the position height of the arc-shaped plate up and down, the distance between the arc-shaped plate and the conveyor belt can be adjusted, which is convenient for the distance between the arc-shaped plate and the conveyor belt to adapt to the passage of product materials of different specifications.

[0025] 3. A spiral conveyor is installed inside the arc-shaped plate.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] For example 1, please refer to Figure 1-6 In an embodiment of the present invention, a material-jumping prevention device for a color sorter includes a conveyor 100. The conveyor 100 includes two baffles 110. Two conveying rollers 120 rotate between the two baffles 110. A conveyor belt 121 is connected to the two conveying rollers 120. Two material-jumping prevention mechanisms 200 are provided on the top of the conveyor belt 121. The material-jumping prevention mechanism 200 includes a support seat 1 210 and a support seat 2 220 that are slidably connected to the baffles 110. An arc plate rotates between the support seat 1 210 and the support seat 2 220. 230, a circular plate 240 is fixed at one end of the arc-shaped plate 230, a shaft 250 is rotated in the middle of the circular plate 240, and an auger 251 is fixed on the outside of the shaft 250, wherein two driving mechanisms 300 are provided on the outside of a baffle 110, and the driving mechanism 300 is used to drive the auger 251 to rotate and convey the intercepted excess materials, and an adjusting mechanism 400 is provided above the anti-jumping mechanism 200, and the adjusting mechanism 400 is used to adjust the distance between the arc-shaped plate 230 and the conveyor belt 121 to adapt to the passage of materials of various specifications.

[0036] Specifically, a curved plate 230 is rotatably arranged on the bottom surface of the conveyor belt 121, and the curved plate 230 is pressed against the surface of the material on the conveyor belt 121, so that the material accumulated on the conveyor belt 121 can be spread out and leveled, and the excess material is squeezed into the inside of the curved plate 230, thereby making the material transported on the conveyor belt 121 more uniform, and effectively preventing the accumulation and jumping of materials on the conveyor belt 121. The curved plate 230 rotates 90 degrees to allow the intercepted material to be placed inside the curved plate 230, and then the auger 251 rotates to transport the material inside the curved plate 230 away from the conveyor belt 121, so as to facilitate and timely cleanup of excess material on the conveyor belt 121, and prevent material accumulation from affecting the smooth feeding and color sorting of the conveyor belt 121.

[0037] like Figure 1 、 Figure 2 and Figure 3 As shown, in this embodiment, a connecting plate 111 is fixed between one ends of the two baffles 110 , a material receiving plate 112 is fixed between one ends of the two baffles 110 , and a supporting plate 130 is fixed between the two baffles 110 .

[0038] In this embodiment, the connecting plate 111 fixes the two baffles 110 together, the receiving plate 112 is convenient for receiving the material released from the external hopper, and the support plate 130 is arranged on the bottom surface of the conveyor belt 121 to support the conveyor belt 121 and prevent the conveyor belt 121 from being pressed down by the material and loosening. A driving motor is installed on the outside of the baffle 110, and the driving motor drives a conveyor roller 120 to rotate so that the conveyor belt 121 transmits and transports the material between the two conveyor rollers 120. The specific structure of this part of the conveyor 100 is the existing technology, and the specific working principle will not be described in detail.

[0039] like Figure 5 As shown, in this embodiment, one edge of the arc-shaped plate 230 is configured as an inclined surface, and a rotating ring 231 rotatably connected to the second support seat 220 is fixed to one end of the arc-shaped plate 230 .

[0040] The inclined edges of the arc plate 230 facilitate the transportation of the accumulated materials into the interior of the arc plate 230. An annular groove 221 is provided on the inner side of the support seat 220. The rotating ring 231 rotates inside the annular groove 221 to enable the arc plate 230 to rotate stably between the support seat 1 210 and the support seat 2 220.

[0041] like Figure 1 and Figure 5 As shown, in this embodiment, a notch is provided on one side of the support seat 1 210 for rotationally connecting with the circular plate 240, a discharge hole 222 is provided on one side of the support seat 220, and a discharge plate fixed to the support seat 220 is arranged on the outer side of the discharge hole 222.

[0042] In this embodiment, the circular plate 240 at one end of the arc plate 230 rotates at the notch position of the support seat 210, so that the support seat 210 stably supports the rotating arc plate 230. When the auger 251 inside the arc plate 230 rotates to convey the material, the material will move along the arc plate 230 toward the discharge hole 222, and then be transported along the discharge plate to the external collection box 510.

[0043] like Figure 1 As shown, in this embodiment, two brackets 500 are fixed to the outside of a baffle 110 , and a material collecting box 510 is placed inside the bracket 500 .

[0044] In this embodiment, the collection box 510 is convenient for receiving the intercepted materials transported from the curved plate 230. When the curved plate 230 rotates back to the material interception position and stops transporting materials, the collection box 510 can be removed from the bracket 500, and then the material in the collection box 510 can be poured into the external hopper and fall back into the conveyor belt 121.

[0045] like Figure 2 、 Figure 4 and Figure 6As shown, in this embodiment, the driving mechanism 300 includes a motor one 310 and a motor two 330 fixedly connected to the baffle 110. A gear 311 is fixed to the output end of the motor one 310. A toothed ring 320 is engaged and driven outside the gear 311. A transmission wheel 321 rotatably connected to the first support seat 210 is fixed to the inner ring side of the toothed ring 320. The transmission wheel 321 is fixedly connected to the circular plate 240. The shaft rod 250 rotatably penetrates through the transmission wheel 321. The output end of the motor two 330 is fixedly connected to the shaft rod 250. An L-shaped frame 331 rotatably connected to the shaft rod 250 is fixed to the outside of one end of the motor two 330. The L-shaped frame 331 is fixedly connected to the first support seat 210.

[0046] In this embodiment, when it is necessary to remove the intercepted material entering the inside of the arc plate 230 from the arc plate 230, the motor one 310 rotates with the gear 311 to make the toothed ring 320 rotate with the transmission wheel 321. The transmission wheel 321 rotates the circular plate 240 on the first support seat 210, thereby making the arc plate 230 rotate 90 degrees between the first support seat 210 and the second support seat 220, making the opening of the arc plate 230 face upward. At this time, the intercepted material falls into the inside of the arc plate 230. Then the motor two 330 rotates with the shaft rod 250 to make the auger 251 rotate inside the arc plate 230 to convey the material. The material is conveyed out along the arc plate 230 through the discharge hole 222 on the second support seat 220. After that, the arc plate 230 is driven to rotate 90 degrees in the reverse direction by the reverse rotation of the motor one 310, so that the inclined surface position of the arc plate 230 is arranged above the conveyor belt 121 again to intercept the material.

[0047] As Figure 2 、 Figure 4 and Figure 6 As shown, in this embodiment, the L-shaped frame 331 improves the stability of the rotation of the shaft rod 250 and also facilitates the fixing of the motor two 330 outside the L-shaped frame 331. A support plate fixedly connected to the first support seat 210 is fixed to the bottom of the motor one 310, so that the motor one 310 can be installed and fixed outside the first support seat 210. One end of the shaft rod 250 penetrates through the first support seat 210 and the transmission wheel 321, and the rotation of the shaft rod 250 does not affect the rotation of the transmission wheel 321.

[0048] Embodiment two, on the basis of embodiment one, in order to adjust the height of the arc plate 230 so that materials of different specifications can be conveyed between the arc plate 230 and the conveyor belt 121.

[0049] As Figure 3 and Figure 4As shown, in this embodiment, the adjusting mechanism 400 includes two U-shaped seats 410. The U-shaped seats 410 are fixedly connected to the baffle 110. A screw rod 420 is screwed on the top of the U-shaped seat 410. A cross beam 430 is rotatably connected between the bottom ends of the two screw rods 420. The bottom surface of the cross beam 430 is fixedly connected to the first support seat 210 and the second support seat 220.

[0050] In this embodiment, when it is necessary to adjust the distance between the arc plate 230 and the conveyor belt 121 to meet the passing of materials of different specifications, rotate the wheels at the tops of the two screw rods 420 simultaneously. The screw rods 420 are screwed and move upward on the U-shaped seats 410. Furthermore, the cross beam 430 at the bottom of the screw rods 420 moves the first support seat 210 and the second support seat 220 upward, so that the arc plate 230 moves upward, increasing the distance between the arc plate 230 and the conveyor belt 121. Similarly, rotating the screw rods 420 in the reverse direction will cause the first support seat 210 and the second support seat 220 to move the arc plate 230 downward, realizing the reduction of the distance between the arc plate 230 and the conveyor belt 121.

[0051] As Figure 3 and Figure 4 shown, in this embodiment, two rectangular chutes are provided at the top of the baffle 110. The first support seat 210 and the second support seat 220 can slide up and down inside the rectangular chutes to realize the adjustment of the position height of the anti-jumping material mechanism 200.

[0052] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.
