DETAILED DESCRIPTION
[0025] The present invention is further described below in conjunction with the embodiments, which are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, other embodiments obtained by ordinary technicians in the field without creative work are all within the protection scope of the present invention.
[0026] See also Figure 1 as well as Figure 2 As shown, this embodiment discloses a roller support frame, including: a frame 101, a roller assembly, a motor 102 and a transmission mechanism, wherein the frame 101 is used to be installed on the ground, and a plurality of clearance grooves 114 are provided on the frame 101; the roller assembly is installed on the frame 101, and the roller assembly is used to convey materials; the motor 102 is installed on the frame 101, and the motor 102 is used to drive the roller assembly to operate; the transmission mechanism is installed on the frame 101, and the motor 102 drives the roller assembly to rotate through the transmission mechanism;
[0027] Among them, the frame 101 is also provided with a tensioning device, which includes a fixed plate 103, a sliding plate 104 and a tensioning wheel 105. The fixed plate 103 is fixedly installed on the side of the frame 101, the fixed plate 103 and the transmission mechanism are installed on the same side, the sliding plate 104 is slidably connected with the frame 101, two sliding holes 106 are provided on the fixed plate 103, and two sliding rods 107 are provided on the sliding plate 104, and the sliding rods 107 are slidably matched with the sliding holes 106; a wave spring 108 is provided between the two sliding rods 107, and the wave spring 108 is connected to the sliding plate 104; a threaded hole 109 is provided on the fixed plate 103, and a screw 110 is provided in the threaded hole 109, and the end of the screw 110 is rotatably connected with the sliding plate 104, and the wave spring 108 is sleeved on the screw 110; the tensioning wheel 105 is rotatably installed on the sliding plate 104, and the tensioning wheel 105 is used to tension the transmission mechanism;
[0028] The utility model mainly includes a frame 101, a pressure roller assembly, a motor 102 and a transmission mechanism. In actual use, after installing the transmission mechanism, the staff needs to tension the transmission mechanism. At this time, the staff rotates the screw 110, and the screw 110 is threadedly matched with the threaded hole 109 on the fixed plate 103. The screw 110 pushes the sliding plate 104 to slide on the mounting frame, thereby driving the tensioning wheel 105 to slowly approach the transmission mechanism. As the screw 110 continues to rotate, the tensioning wheel 105 slowly squeezes the transmission mechanism until the transmission mechanism is stable. After that, the screw 110 is no longer rotated. At this time, the wave spring 108 is located between the sliding plate 104 and the fixed plate 103, and the wave spring 108 is sleeved on the screw 110. The sliding plate 104 and the fixed plate 103 squeeze the wave spring 108. After the wave spring 108 is compressed, it applies a reaction force to the screw 110, making the screw 110 more stable. The function of the slide bar 107 is to provide a guide for the sliding of the sliding plate 104. At this time, when it is necessary to convey materials, turn on the motor 102, and the motor 102 rotates and drives the pressure roller assembly to convey the materials through the transmission mechanism. The advantage of this setting is that the transmission mechanism is tensioned by the free movement of the tension wheel 105, making the transmission mechanism more stable when working.
[0029] In some embodiments, the pressure roller assembly includes a first fixed pressure roller 111, a second fixed pressure roller 112 and a movable pressure roller 113. One end of the first fixed pressure roller 111 passes through a make way slot 114 and is connected to the motor 102, and the other end passes through the make way slot 114 and is rotatably connected to the frame 101; the motor 102 is connected to the first fixed pressure roller 111, and the motor 102 is used to drive the first fixed pressure roller 111 to rotate. The first fixed pressure roller 111 is connected to the second fixed pressure roller 112 through the transmission mechanism, and both ends of the second fixed pressure roller 112 and the movable pressure roller 113 are rotatably connected to the frame 101.
[0030] In actual use, the motor 102 rotates to drive the first fixed pressure roller 111 to rotate, and the first fixed pressure roller 111 drives the second fixed pressure roller 112 to rotate through the transmission mechanism. The function of the movable roller is to change the transmission direction of the material.
[0031] In some embodiments, the frame 101 includes a sliding frame 115 and a fixed frame 116. The sliding frame 115 is slidably arranged on the fixed frame 116. A telescopic assembly 117 is arranged on the sliding frame 115. The fixed end of the telescopic assembly 117 is connected to the sliding frame 115, and the movable end is connected to the fixed frame 116; a transmission mechanism is arranged on the sliding frame 115, and a plurality of clearance grooves 114 are arranged on the sliding frame 115 and the fixed frame 116. Both ends of the movable roller are rotatably mounted on the sliding frame 115, and the tensioning device is installed as a whole on the sliding frame 115. The second fixed pressure roller 112 is rotatably mounted on the sliding frame 115, and is connected to the transmission mechanism through the clearance groove 114 on the fixed frame 116; the first fixed pressure roller 111 is rotatably connected to the fixed frame 116, and is connected to the transmission mechanism through the clearance groove 114 on the sliding frame 115.
[0032] In actual use, when it is necessary to adjust the distance between the first fixed pressure roller 111 and the second fixed pressure roller 112, the telescopic component 117 is first controlled to extend or shorten. When the telescopic component 117 is extended, since the fixed frame 116 is fixedly installed on the ground, the telescopic component 117 will push the sliding frame 115 to rise as a whole, and the make way groove 114 on the fixed frame 116 and the make way groove 114 on the sliding frame 115 will make way for the second fixed pressure roller 112 and the first fixed pressure roller 111 respectively; after the sliding frame 115 is raised, the distance between the first fixed pressure roller 111 and the second fixed pressure roller 112 becomes larger, which is convenient for conveying materials with larger thickness. When the output shaft of the telescopic component 117 is retracted, the distance between the first fixed pressure roller 111 and the second fixed pressure roller 112 becomes smaller, which is convenient for conveying materials with smaller thickness; the advantage of such a setting is that it is convenient for conveying materials of different specifications and has a wider range of applications.
[0033] In some embodiments, the transmission mechanism includes a driving wheel 118, a driven wheel 119 and two mounting wheels 120, the driving wheel 118 is installed at the end of the first fixed pressure roller 111, the driven wheel 119 is installed at the end of the second fixed pressure roller 112, the two mounting wheels 120 are rotatably installed on the mounting frame, and a belt 121 is sleeved on the driving wheel 118, the driven wheel 119 and the two mounting wheels 120; the tensioning wheel 105 is used to contact the belt 121.
[0034] During actual use, the first fixed pressure roller 111 rotates and drives the driving wheel 118 to rotate. Under the action of the friction force of the belt 121, the driving wheel 118 rotates and drives the two mounting wheels 120 and the driven wheel 119 to rotate. The purpose of setting two mounting wheels 120 is to facilitate adapting to pressure roller assemblies of different heights. When the distance between the first fixed pressure roller 111 and the second fixed pressure roller 112 is too large, the belt 121 only needs to be wound around one mounting wheel 120.
[0035] In some embodiments, a guide rod 122 is further provided on the sliding frame 115 , a limit plate 123 is provided at the end of the guide rod 122 , the end of the guide rod 122 is connected to the fixed frame 116 , and the limit plate 123 is used to contact the upper end surface of the sliding frame 115 .
