Detailed Description
The present utility model will be described in further detail with reference to the accompanying drawings.
The embodiment of the utility model discloses a belt wheel type rotating device 1 applied to an injection molding machine.
Referring to fig. 1, a rotating apparatus 1 includes: the rotary template 11, the rotary driving mechanism 12 and the supporting plate 13 fixedly connected to the frame, wherein the rotary template 11 is rotationally connected above the supporting plate 13, and the rotary driving mechanism 12 is arranged close to one side of the supporting plate 13 far away from the rotary template 11; the rotation driving mechanism 12 includes a motor 121, a first pulley 122, a second pulley 123, and a timing belt 124 connected between the first pulley 122 and the second pulley 123. The wheel core of the first belt wheel 122 is connected to the output end of the motor 121, and the wheel core of the second belt wheel 123 is fixedly connected to the rotary template 11.
Specifically, the motor 121 may be a servomotor 121, the first pulley 122 may be a small pulley, and the second pulley 123 may be a large pulley. The servo motor 121 drives the small belt pulley to rotate, the small belt pulley drives the large belt pulley to rotate through the synchronous belt 124, and the large belt pulley drives the rotary template 11 to rotate.
Since the timing belt 124 is softer than the first pulley 122 and the second pulley 123, the main wear part is the timing belt 124 having a softer material when the rotating device 1 is operated. The operation of replacing the timing belt 124 is simpler, and the price of the timing belt 124 is also cheaper.
The first pulley 122 and the second pulley 123 are respectively engaged with the timing belt 124 in a toothed manner, that is, the first pulley 122 and the second pulley 123 are both toothed pulleys, and the timing belt 124 is a toothed belt. By the tooth engagement of the timing belt 124, slip between the timing belt 124 and the first pulley 122, the second pulley 123 can be reduced, which contributes to precise control of the rotation angle of the rotary die plate 11.
Referring to fig. 1, the rotating apparatus 1 further includes a bearing 14, and a housing of the bearing 14 is fixedly coupled to the support plate 13; one end of the inner shell of the bearing 14 is fixedly connected to the wheel core of the second belt wheel 123, and specifically, a first threaded fastener 15 is arranged on the wheel core of the second belt wheel 123 in a penetrating manner and is in threaded connection with a first threaded hole of the inner shell of the bearing 14; the other end of the inner housing of the bearing 14 is fixedly connected to the rotating die plate 11, and specifically, a second threaded fastener 16 is inserted through the rotating die plate 11 and is screwed into a second threaded hole of the inner housing of the bearing 14. Thus, the power of the rotation of the second pulley 123 is transmitted to the rotary die plate 11.
Specifically, the supporting plate 13 is provided with a through hole 131, one end of the through hole 131 near the rotating template 11 is provided with an annular mounting groove 1311, the bearing 14 is arranged in the through hole 131 in a penetrating manner, and the shell of the bearing 14 is fixedly connected in the mounting groove 1311 of the supporting plate 13.
A supporting pad 132 for supporting the rotary template 11 is sandwiched between the rotary template 11 and the supporting plate 13, and the supporting pad 132 is fixedly connected to the supporting plate 13. In operation, the rotary template 11 rotates on the support pad 132, so that the friction area of the rotary template 11 can be reduced, the friction force of the rotary template 11 can be reduced, and the rotation of the rotary template 11 can be facilitated.
Referring to fig. 2 and 3, in order to facilitate the pouring of oil and water into the bearing 14, the adapter plate 17 is provided with a water pipe hole 171 through which a water supply pipe penetrates. An adapter plate 17 is fixedly connected to one side, away from the bearing 14, of the wheel core of the second belt wheel 123, and the adapter plate 17 is connected with an oil pipe joint 172. The oil line connection 172 communicates with a cylindrical through bore formed in the inner housing of the bearing 14.

For example: the preset state is that the rotary template 11 rotates 180 degrees, the positioning holes 191 and the positioning pins 192 are overlapped in the vertical direction, and the positioning pins 192 extend into the positioning holes 191. If the rotary template 11 is actually rotated 180 degrees, the positioning pins 192 extend into the positioning holes 191, and then the ejection mechanism 18 ejects the product; if the rotary template 11 is not rotated 180 degrees, the positioning pin 192 cannot extend into the positioning hole 191, then the machine alarms, and the machine needs to be restarted and the positions of the positioning pin 192 and the positioning hole 191 are adjusted.
Further, the positioning hole 191 and the positioning pin 192 are tapered fit. For example: the preset state is that the positioning pin 192 stretches into the positioning hole 191 after the rotating template 11 rotates 180 degrees, and the positioning pin 192 can stretch into the positioning hole 191 when the actual rotating angle of the rotating template 11 is more than 175 degrees and less than 185 degrees. Thus, the rotation angle of the rotary template 11 is corrected, and the rotary template 11 can be conveniently rotated 180 degrees next time; and the number of alarms of the machine can be reduced.
Referring to fig. 1, further, in order to reduce wear of the positioning hole 191, the inner wall of the positioning hole 191 is sleeved with a positioning sleeve 194.
