[0031] Example 1

[0032] Embodiment 1 of this utility model provides a waste discharge tape winding mechanism. The mechanism includes a fixed frame, a winding assembly, and a tape breakage detection assembly. The winding assembly and the tape breakage detection assembly are fixed on the fixed frame, and the tape breakage detection assembly is disposed on the side of the winding assembly.

[0033] In one optional implementation of this embodiment, such as Figure 1 As shown, Figure 1 A schematic diagram of the waste discharge tape winding mechanism in Embodiment 1 of this utility model is shown. The mechanism includes a fixed frame 1, a winding assembly 2, and a tape breakage detection assembly 3. The winding assembly 2 and the tape breakage detection assembly 3 are fixed on the fixed frame 1, and the tape breakage detection assembly 3 is disposed on the side of the winding assembly 2.

[0034] In one optional implementation of this embodiment, such asFigure 2 and Figure 3 as shown, Figure 2 The utility model discloses a winding assembly structure schematic diagram in embodiment one, Figure 3 The utility model discloses a winding assembly structure schematic diagram in embodiment one, The winding torque motor 22 is hung under the fixed frame 1, the first end of the gas expansion axle 21 is connected with the winding torque motor 22, and the two winding units 4 are sleeved on the gas expansion axle 21.

[0035] Specifically, in actual work, the winding torque motor 22 drives the gas expansion axle 21 to rotate and drives the winding unit 4 to rotate and wind.

[0036] In one optional implementation manner of the embodiment, as shown in Figure 4 , Figure 5 and Figure 6 as shown, Figure 4 The utility model discloses a winding unit structure schematic diagram in embodiment one, Figure 5 The utility model discloses a winding unit structure schematic diagram in embodiment one, Figure 6 The utility model discloses a winding unit structure schematic diagram in embodiment one, The winding unit 4 comprises an assembly inner ring 41, an assembly outer ring 42, a friction plate 43 and an adjusting screw 44, the assembly inner ring 41 is sleeved and fixed on the gas expansion axle 21, the assembly outer ring 42 is sleeved on the assembly inner ring 41, a ball bearing 45 is arranged between the assembly outer ring 42 and the assembly inner ring 41, the friction plate 43 is sleeved on the gas expansion axle 21 and is attached to one side (the right side in the drawing) of the assembly inner ring 41 and one side (the right side in the drawing) of the assembly outer ring 42, and the adjusting screw 44 passes through the friction plate 43 and is embedded in the assembly inner ring 41.

[0037] In one optional implementation manner of the embodiment, a spring 441 is fixedly sleeved on any one adjusting screw 44, one end of the spring 441 is fixedly sleeved on the adjusting screw 44, and the other end is pressed on the side surface of the assembly inner ring 41.

[0038] Specifically, when the waste rubber belt is discharged, it is adhered to the circulating belt, and a certain force is needed to separate it from the circulating belt and wind it up.

[0039] In actual winding work, the adjusting screw is passed through the friction plate and embedded in the assembly inner ring, so that the spring arranged on the adjusting screw is pressed tightly, and the friction plate is pressed tightly on the side surface of the assembly inner ring and the side surface of the assembly outer ring.

[0040] When the air inflation shaft drives the assembly inner ring to rotate, the friction plate adheres to the surface of the assembly outer ring to generate static friction, thereby driving the assembly outer ring to rotate.

[0041] The waste rubber belt is wound on the assembly outer ring for winding. When the assembly outer ring has no waste rubber belt wound thereon, the rotational linear speed of the assembly outer ring, the assembly inner ring and the air inflation shaft remains consistent. When the waste rubber belt starts to be wound on the assembly outer ring, the rotational linear speed of the assembly outer ring decreases. However, due to the friction force of the friction plate on the side surface of the assembly outer ring, the assembly outer ring generates a certain torque force. The torque force is greater than the adhesion force between the waste rubber belt and the circulating belt, so that the waste rubber belt can be pulled off from the circulating belt and wound.

[0042] After winding is completed, the waste rubber belt stops being discharged, but the torque force caused by the friction force of the friction plate still exists in the assembly outer ring. Since the torque force is smaller than the force for tearing the waste rubber belt, the assembly outer ring stops rotating, thereby stopping winding of the waste rubber belt.

[0043] Further, in the actual cutting process, the waste rubber belt is usually discharged simultaneously along multiple conveying paths. In the embodiment, two conveying paths are discharged simultaneously. Since the number of winding units arranged on the air inflation shaft in the embodiment is two, and the rotational speed of the air inflation shaft is constant, the rotational speed of the assembly inner ring driving the two winding units is constant. When the winding diameters of the waste rubber belts wound by the two winding units are inconsistent, the adjusting screws of the two winding units need to be adjusted. For the winding unit corresponding to the waste rubber belt with a larger winding diameter and a relatively smaller winding linear speed, the adjusting screw of the winding unit is tightened, so that the compression force of the spring on the adjusting screw on the friction plate is increased, the friction force of the friction plate on the assembly outer ring is increased, the torque force of the assembly outer ring is increased, and the rotational speed of the assembly outer ring is increased. For the winding unit corresponding to the waste rubber belt with a smaller winding diameter and a relatively larger winding linear speed, the adjusting screw of the winding unit is loosened, so that the compression force of the spring on the adjusting screw on the friction plate is decreased, the friction force of the friction plate on the assembly outer ring is decreased, the torque force of the assembly outer ring is decreased, and the rotational speed of the assembly outer ring is decreased. Such adjustment makes the winding linear speeds of the two winding units consistent, so that the waste rubber belt cannot be wound or torn due to the torque force of the assembly outer ring being too small or too large, and the winding efficiency of the waste rubber belt is improved.

[0044] It should be noted that in the initial state, the spring on the adjusting screw compresses the friction plate, and then generates the friction force of the friction plate on the assembly outer ring, and generates the torque force, which needs to be greater than the adhesion force of the waste rubber belt on the circulating belt, that is, needs to be greater than the force of pulling the waste rubber belt on the circulating belt, but needs to be less than the force of tearing the waste rubber belt.

[0045] Here, the winding unit is sleeved on the air expansion shaft driven by the winding torque motor, the assembly inner ring and the assembly outer ring are arranged on the winding unit and are sleeved with each other, and the friction plate is fixed on the side surface of the assembly inner ring and the assembly outer ring by the adjusting screw. By adjusting the compression degree of the spring on the adjusting screw, the friction force of the friction plate on the assembly outer ring is controlled, the winding torque of the assembly outer ring is changed, and then the winding linear speed of the assembly outer ring is changed, so that the winding units at different positions match the winding conditions of the waste rubber belts at corresponding positions, and the winding efficiency of the waste rubber belts is effectively improved.

[0046] In an optional implementation manner of the embodiment, the number of adjusting screws arranged on the winding unit is 1-10.

[0056] ​​Specifically, in actual work, the waste rubber belt needs to pass through the broken belt sensor assembly during the process of being pulled out from the circulating belt to the winding assembly for winding, that is, when the waste rubber belt passes normally, the sensing signal emitted by the sensing signal transmitter is blocked by the waste rubber belt, and the sensing signal receiver cannot receive the sensing signal, which indicates that the waste rubber belt does not have a broken belt phenomenon; when the sensing signal receiver receives the sensing signal, it indicates that the belt blocked between the sensing signal transmitter and the sensing signal receiver does not exist, that is, a broken belt phenomenon occurs and needs to be handled.

[0057] Further, the broken belt detection sensor assembly adopts an infrared broken belt detection sensor assembly.
