The brush wire of insufficient length passes through the feeding trough close to the side of the first cylinder and falls on the top of the second conveyor belt.

[0021] The present invention facilitates the removal of too short brush filaments by arranging the coordination of structures such as the leveling component and the sorting component, and pushes the bottom of the brush filaments to level them by the push plate, and when the push plate contacts the extrusion block, the extrusion block is pushed to squeeze the clamping plate, so that the clamping plate and the supporting plate are closed, and the brush filaments of sufficient length are clamped and fixed, and then the push plate pushes the sliding bracket to move to the top of the lower trough, and the brush filaments are separated by pressing down the sorting component, and the brush filaments are sorted, thereby separating the specifications of the brush filaments.

[0029] 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 described embodiments 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 creative work are within the scope of protection of the present invention.
[0030] like Figures 1 to 6 As shown, the present invention provides a sorting device for brush processing, comprising a main frame 1, a feed port 2 is provided on the top of the main frame 1, a first conveyor belt 3 is provided in the middle of the main frame 1, a vibration component 4 is provided at the bottom of the main frame 1, and a leveling component 6 and a sorting component 7 are provided on the side of the main frame 1 away from the feed port 2;
[0031] The vibration assembly 4 includes a motor 41 fixedly connected to the bottom of the main frame 1, a turntable 42 is fixedly connected to the output end of the motor 41, a transmission plate 43 is rotatably connected to the middle of the turntable 42, a vibration plate 44 is hinged at one end of the transmission plate 43, and a first spring 45 is arranged at the bottom of the vibration plate 44.
[0032] The above scheme is adopted: the turntable 42 is driven to rotate by the motor 41, so that the turntable 42 drives the vibration plate 44 to reciprocate through the transmission plate 43, so that the vibration plate 44 vibrates, and the brush wires are shaken and scattered by the vibration plate 44, and then the brush wires are pushed to be leveled and fixed by the leveling component 6, and then the brush wires are pressed down by the sorting component 7 to separate the brush wires.
[0033] like Figure 1 and Figure 2As shown, the main frame 1 at one end between the first conveyor belt 3 and the leveling assembly 6 is inclined downward toward the leveling assembly 6, and the unloading end of the feed port 2 is provided with a unloading roller 5 rotatably connected to the main frame 1, and a unloading trough 8 is fixedly connected to the side of the main frame 1, and a second conveyor belt 9 is provided at the lower side of the unloading trough 8.
[0034] The above scheme is adopted: by setting a slope between the first conveyor belt 3 and the leveling component 6, the dispersed brush filaments can be easily dropped to the push plate 62, and the discharge roller 5 set at the discharge end at the feed port 2 can facilitate the discharge roller 5 to periodically convey a fixed amount of brush filaments downward to avoid too many brush filaments that are difficult to shake open. The setting of the discharge trough 8 and the second conveyor belt 9 can facilitate the separation of brush filaments that do not meet the length standards.
[0035] like Figure 2 and Figure 3 As shown, the turntable 42 is rotatably connected to the main frame 1, the top of the vibration plate 44 penetrates the main frame 1 and extends to the inside of the main frame 1, the vibration plate 44 is slidably connected to the main frame 1, and a limit rod is provided at the bottom of the vibration plate 44, a protrusion is provided on the top of the vibration plate 44, the first spring 45 is sleeved on the limit rod, and the two ends of the first spring 45 are fixedly connected to the main frame 1 and the vibration plate 44 respectively.
[0036] The above scheme is adopted: by setting a vibration component 4, the motor 41 drives the turntable 42 to rotate, so that the turntable 42 drives the vibration plate 44 to reciprocate through the transmission plate 43, and at the same time the first spring 45 reduces the vibration of the vibration plate 44, so that the vibration plate 44 vibrates, and the raised block arranged on the top of the vibration plate 44 can shake the vibration of the vibration plate 44, so that the brush filaments are shaken and scattered by the vibration plate 44.
[0037] like Figure 4 , Figure 5 and Figure 6 As shown, the leveling assembly 6 includes a first cylinder 61 and a sliding rod 63. The output end of the first cylinder 61 is fixedly connected to a push plate 62. The middle part of the sliding rod 63 is slidably connected to a sliding bracket 64. One end of the sliding rod 63 close to the first cylinder 61 is sleeved with a tension spring 65. The middle part of the sliding bracket 64 is slidably connected to an extrusion block 66 and a clamping plate 67. A pair of second springs 68 are sleeved on the top of the sliding bracket 64.
[0038] The above scheme is adopted: by setting a leveling component 6, the first cylinder 61 drives the push plate 62 to move, so that the push plate 62 pushes one end of the brush wire to move, and the brush wire is leveled to separate the brush wires that are insufficient in length. The setting of the slide rod 63 and the sliding bracket 64 enables the push plate 62 to move and simultaneously push the sliding bracket 64 to move synchronously along the slide rod 63. The push plate 62 pushes the extrusion block 66, so that the extrusion block 66 squeezes the clamping plate 67, and the clamping plate 67 moves down to clamp the brush wire.
[0039] like Figure 4 , Figure 5 and Figure 6 As shown, the first cylinder 61 is fixedly connected to the top of the main frame 1, and a supporting slide plate is provided on the top of the main frame 1. The push plate 62 is slidably connected to the supporting slide plate, and the push plate 62 is located on the side of the first cylinder 61 close to the first conveyor belt 3. The push plate 62 is in conflict with the sliding bracket 64 and the extrusion block 66. A bearing plate extends from one side of the sliding bracket 64, and a pair of first support rods are provided on the top of the sliding bracket 64. The clamping pressure plate 67 is slidably connected to the first support rod, and the clamping pressure plate 67 is located on the top of the bearing plate and in conflict with the bearing plate. One end of the extrusion block 66 is inserted into the middle of the pair of first support rods and in conflict with the top of the clamping pressure plate 67. The second spring 68 is sleeved on the bottom of the pair of first support rods, and the second spring 68 is located at the bottom of the clamping pressure plate 67.
[0040] The above scheme is adopted: by setting the first cylinder 61, it is convenient to push the push plate 62 and the sliding bracket 64 to move, and the push plate 62 is slidably connected to the supporting slide plate. The push plate 62 can maintain stable sliding and is easy to reset. The setting of the slide rod 63 can pull the sliding bracket 64 to reset. The first support rod set on the top of the sliding bracket 64 allows the clamping plate 67 to maintain a horizontal state and slide up and down, so as to cooperate with the bearing plate to clamp the brush wire of sufficient length. The second spring 68 set at the bottom of the clamping plate 67 can push the clamping plate 67 to rise after the extrusion block 66 releases the extrusion of the clamping plate 67, thereby releasing the clamping of the brush wire.
[0041] like Figure 4 and Figure 6 As shown, the sorting component 7 includes a second cylinder 71, the output end of the second cylinder 71 is fixedly connected to a support frame 72, a pair of pressure rods 73 are fixedly connected to the bottom of the support frame 72, and a baffle 74 is slidably connected to the side of the support frame 72. The second cylinder 71 is fixedly connected to the middle of the second support rod on the side of the main frame 1, the support frame 72 is slidably connected to the second support rod, the pressure rod 73 is movably connected to the top of the unloading chute 8, and the baffle 74 is arranged at the slope between the first conveyor belt 3 and the leveling component 6, and the baffle 74 is slidably connected to the main frame 1
[0042] The above scheme is adopted: by setting up the sorting component 7, the second cylinder 71 drives the support frame 72 to slide up and down, and the support frame 72 drives the pressure rod 73 to press down, and the brush wire is pressed down into the discharge chute 8. At this time, the brush wire not clamped by the clamping plate 67 will be separated from the clamped brush wire, and the baffle 74 is driven up and down by the support frame 72 to block the slope, so that when the push plate 62 pushes the brush wire to level it, the brush wire at the first conveyor belt 3 will temporarily not enter the leveling component 6, and will fall to the leveling component 6 under the action of gravity after the baffle 74 is opened.
[0043] like Figures 1 to 6 As shown, the present invention proposes a sorting method for brush processing, comprising the following steps:
[0044] S1, the brush filaments are placed into the feed port 2, and a portion of the brush filaments are periodically conveyed downward by the unloading roller 5. At this time, the motor 41 drives the turntable 42 to rotate, so that the turntable 42 drives the vibration plate 44 to reciprocate through the transmission plate 43, so as to shake the brush filaments moved to the vibration component 4, and the brush filaments are conveyed to the push plate 62 by the first conveyor belt 3;
[0045] S2. After the unfolded brush wire is transported to the push plate 62, when there is a certain amount of brush wire inside the push plate 62, the second cylinder 71 pushes the support frame 72 to move downward a certain distance, so that the baffle 74 falls to adjust the wind speed of the slope, and then the first cylinder 61 pushes the push plate 62 to move to the lower trough 8, so that the bottom of the brush wire is pushed and leveled. When the push plate 62 collides with the extrusion block 66, the brush wire that meets the length standard has entered the bottom of the clamping plate 67, and then the push plate 62 pushes the extrusion block 66 to squeeze the clamping plate 67, so that the clamping plate 67 and the bearing plate are closed, the brush wire is clamped and fixed, and then the push plate 62 pushes the sliding bracket 64 to move to the top of the lower trough 8;
[0046] S3, after the push plate 62 pushes the sliding bracket 64 and the brush wire to move to the top of the discharge trough 8, the second cylinder 71 pushes the support frame 72 to move downward, so that the pressure rod 73 presses the brush wire downward, and the brush wire clamped by the clamping plate 67 and the supporting plate falls into the discharge trough 8 on the side away from the first cylinder 61. The brush wire of insufficient length passes through the discharge trough 8 close to the first cylinder 61 and falls on the top of the second conveyor belt 9. Then the first cylinder 61 pulls the push plate 62 to reset until the clamping plate 67 contacts the support frame 72 and continues to move, so that the clamping plate 67 is pushed upward by the second spring 68, so that the clamped brush wire falls to the top of the second conveyor belt 9.
[0047] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
