[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0021] Reference Figure 1 A device for making brush strips, comprising a bottom plate 1, two brackets 2 facing each other are fixed on the bottom plate 1, and slidable sliders 3 are arranged on the two brackets 2, and the bottom surfaces of the sliders 3 and the top surfaces of the brackets 2 are mutually fitted, and connecting rods 4 are fixed on the two sliders 3, and push plates 5 are fixed on the ends of the two connecting rods 4 away from the corresponding sliders 3;
[0022] The two sliders 3 are both arranged on the corresponding brackets 2 through a sliding assembly, and the sliding assembly includes two side plates 61, a sliding rod 62 and a spring 63. The two side plates 61 are both fixed on the bracket 2, and the two side plates 61 are arranged opposite to each other. The sliding rod 62 is fixed between the two side plates 61, and the sliding rod 62 passes through the slider 3 and is slidably connected with the slider 3. One end of the spring 63 is connected to one of the side plates 61, and the other end of the spring 63 is connected to the slider 3. When the slider 3 moves, the sliding rod 62 limits the movement of the slider 3. In addition, the bottom surface of the slider 3 and the top surface of the bracket 2 fit each other. This design can ensure the stability of the slider 3 during movement.
[0023] Two driving components are arranged on the bottom plate 1, and the driving components include a motor 71, an eccentric wheel 72, a connecting block 73 and a slideway 74. The eccentric wheel 72 is fixedly sleeved on the output shaft of the motor 71, and the eccentric wheel 72 is eccentrically arranged between the output shaft of the motor 71. The connecting block 73 is fixed to the bottom surface of the slider 3, and the slideway 74 is provided on the bracket 2. The connecting block 73 slides in the slideway 74. The two eccentric wheels 72 are respectively arranged opposite to the two connecting blocks 73. When the motor 71 is running, it can drive the eccentric wheels 72 The eccentric wheel 72 can continuously squeeze the connecting block 73 when rotating, and at the same time, under the elastic force of the spring 63, the connecting block 73 can continuously reciprocate, and the connecting block 73 can drive the slider 3 to move when moving, and the push plate 5 will also move accordingly. Therefore, when the two motors 71 are running, the two push plates 5 can move synchronously and continuously reciprocate. When the bristles are placed between the two push plates 5, the two reciprocating push plates 5 can continuously slap the two ends of the bristles to align the bristles;
[0024] The bottom plate 1 is also provided with an adjustment component, which includes two fixed plates 81, an adjustment screw 82, a limit rod 83 and two adjustment blocks 84. The two fixed plates 81 are respectively fixed at both ends of the bottom plate 1, the adjustment screw 82 is rotatably installed between the two fixed plates 81, the limit rod 83 is fixed between the two fixed plates 81, the two adjustment blocks 84 are both threadedly sleeved on the adjustment screw 82, and the two adjustment blocks 84 are both slidably sleeved on the limit rod 83. The two adjustment blocks 84 are respectively connected to the two motors 71, and the adjustment screw 82 is provided with two threads of the same length and opposite directions. When 82 rotates, the two adjustment blocks 84 can synchronously move away from or towards each other, and the two motors 71 on the two adjustment blocks 84 will also move accordingly. When the two motors 71 move away from each other, the two eccentric wheels 72 will also move away from each other. When the eccentric wheel 72 moves away from the connecting block 73, the moving stroke of the connecting block 73 will become smaller, and the moving stroke of the push plate 5 will also become smaller. When the eccentric wheel 72 approaches the connecting block 73, the moving stroke of the connecting block 73 will become larger, and the moving stroke of the push plate 5 will also become larger. Therefore, the staff can control the moving stroke of the two push plates 5 by adjusting the position of the two eccentric wheels 72.
[0025] The specific working principle of the utility model is as follows:
[0026] When the device for making brush strips proposed by the utility model is actually used, when the bristles are slapped and aligned, the staff starts the two motors 71 to make the two motors 71 run synchronously. When the motor 71 runs, it can drive the eccentric wheel 72 to rotate. When the eccentric wheel 72 rotates, it can continuously squeeze the connecting block 73. At the same time, under the elastic force of the spring 63, the connecting block 73 is continuously reciprocated. When the connecting block 73 moves, it can drive the slider 3 to move, and the push plate 5 will also move accordingly. Therefore, when the two motors 71 are running, the two push plates 5 can move synchronously and continuously reciprocate. When the bristles are placed between the two push plates 5, the two reciprocating push plates 5 can continuously slap the two ends of the bristles to align the bristles.
[0027] When adjusting the movement stroke of the two push plates 5, the staff rotates the adjusting screw 82. A handle is installed at one end of the adjusting screw 82 to facilitate the staff to rotate the adjusting screw 82. Under the limiting action of the limiting rod 83, the adjusting screw 82 can drive the two adjusting blocks 84 to move synchronously when it rotates. Since the adjusting screw 82 is provided with two sections of threads of the same length and in opposite directions, when the adjusting screw 82 is rotated, the two adjusting blocks 84 can move away from or towards each other synchronously, and the two motors 71 on the two adjusting blocks 84 will also move accordingly. When the two motors 71 move away from each other, the two eccentric wheels 72 will also move away from each other. When the eccentric wheel 72 moves away from the connecting block 73, the moving stroke of the connecting block 73 will become smaller, and the moving stroke of the push plate 5 will also become smaller. When the eccentric wheel 72 approaches the connecting block 73, the moving stroke of the connecting block 73 will become larger, and the moving stroke of the push plate 5 will also become larger. Therefore, the staff can control the moving stroke of the two push plates 5 by adjusting the positions of the two eccentric wheels 72, so that the two push plates 5 can align bristles of different sizes. In summary, the staff only needs to rotate the adjusting screw 82 to adjust the moving stroke of the two push plates 5, and the operation is convenient.
[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
