Description

Technical Field

[0001] The invention relates to the technical field of stirring equipment, in particular to a rubber raw material stirring pretreatment equipment with a preheating function. Background Art

[0002] Rubber is divided into two types: natural rubber and synthetic rubber. Natural rubber is made by extracting gum from plants such as rubber trees and rubber grass; synthetic rubber is obtained by polymerization of various monomers. In modern industrial processing, finished rubber is obtained by injecting rubber raw materials into a mixer and heating and stirring.

[0003] Due to the special properties of rubber materials, there are often some defects that affect its quality. Bubbles are one of the common defects in rubber products. The formation of bubbles may be due to the failure to fully mix the rubber during the mixing process, resulting in the non-volatile body being wrapped in the rubber product. Bubbles will affect the mechanical properties and sealing properties of rubber products. During the heating process, uneven heating will cause uneven internal stress and cause cracks. Summary of the invention

[0004] The purpose of the present invention is to provide a rubber raw material stirring pretreatment device with a preheating function to solve the problems in the prior art.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: A rubber raw material stirring and pretreatment equipment with a preheating function comprises a top cover, a first motor, an infrared probe, a stirring mechanism, a chassis and a heating mechanism, the top cover is fixedly connected to the first motor, the infrared probe, the stirring mechanism and the heating mechanism, the output end of the first motor is transmission-connected to the stirring mechanism, the infrared probe is connected to the stirring mechanism and the heating mechanism through electrical signals, and the chassis is fixedly connected to the heating mechanism.

[0006] The stirring device is used to stir rubber raw materials so that they can achieve mechanical properties and sealing properties that meet the standards. The rubber raw materials are injected into the device through the top cover. The first motor outputs torque to the stirring mechanism to stir the raw materials. The heating mechanism provides heat to the whole machine to heat the raw materials. During the heating process, due to the fact that the raw materials are not fully mixed, unvolatile gases are wrapped in the rubber products, or the rubber is heated unevenly, which will affect the quality of rubber stirring. The infrared probe is used to perform infrared detection on the rubber being stirred. In the infrared microwave detection, bubbles exist on the rubber, which will produce color difference, and the areas with uneven heating can be detected. The infrared probe sends electrical signals to the stirring mechanism and the heating mechanism. The stirring mechanism continuously adjusts the stirring density of the stirring raw materials to eliminate bubbles. The heating mechanism adjusts the heating temperature of the interval to make the rubber raw materials evenly heated.

[0007] Furthermore, the stirring mechanism includes a main shaft, a top plate, a first gear and an inclined threaded rod. The top plate is fixedly connected to the top cover, the main shaft is rotatably connected to the top plate, the main shaft is transmission-connected to the output end of the first motor, the first gear is fixedly connected to the main shaft, two groups of inclined threaded rods are provided, the two groups of inclined threaded rods are meshed with the tooth surface of the first gear, the two groups of inclined threaded rods are rotatably connected to the top plate, and the inclined threaded rods are connected to the infrared probe via electrical signals.

[0008] The output torque of the first motor is transmitted to the inclined threaded rod through the main shaft and the first gear, driving the inclined threaded rod to rotate on the top plate to stir the rubber raw material. According to the electrical signal of the infrared probe, the inclination degree of the inclined threaded rod is adjusted, thereby adjusting the stirring fineness of the stirring raw material and eliminating bubbles on the raw material.

[0009] Furthermore, the heating mechanism includes a bottom cylinder, a second motor, a third motor, a first gear ring, a second gear ring, a mixing drum, a heating resistor ring, a sliding rod and a variable resistance mechanism. The mixing drum is fixedly connected to the top cover and the bottom cylinder. The first gear ring and the second gear ring are slidably connected to the bottom cylinder. The second motor and the third motor are fixedly connected to the bottom cylinder. A first tooth head is provided at the output end of the second motor, and a second tooth head is provided at the output end of the third motor. The first tooth head is meshed with the tooth surface of the first gear ring, and the second tooth head is meshed with the tooth surface of the second gear ring. Two groups of sliding rods and two groups of variable resistance mechanisms are provided. The two groups of sliding rods are fixedly connected to the first gear ring and the second gear ring. The variable resistance mechanism is slidably connected to the heating resistor ring and the sliding rod. The heating resistor ring is fixedly connected to the mixing drum. The second motor, the third motor and the variable resistance mechanism are connected to the infrared probe through electrical signals.

[0010] The heating mechanism heats the rubber raw material by energizing a heating resistor coil fixed on the mixing drum to generate heat. When the infrared probe detects that there are areas of raw material that are heated unevenly, an electrical signal is sent to the second motor and the third motor. The second motor and the third motor output torque to the first gear ring and the second gear ring through the first gear head and the second gear head respectively. The first gear ring and the second gear ring rotate to drive the two groups of variable resistance mechanisms to slide to different positions on the heating resistor coil. The resistance value of the heating resistor coil located at the two groups of variable resistance mechanisms is changed according to the electrical signal, so that the heating rate of the section is changed, and then the area with uneven heating is heated to make it heated evenly.

[0011] Furthermore, the variable resistance mechanism includes a housing, a fourth motor, a bevel gear set, a three-stage transmission wheel set and a three-stage resistance increasing mechanism. The housing is slidingly connected to the sliding rod, the fourth motor, the three-stage transmission wheel set and the three-stage resistance increasing mechanism are all fixedly connected to the housing, the output end of the fourth motor is transmission-connected to the bevel gear set, the three-stage transmission wheel set is transmission-connected to the bevel gear set and the three-stage resistance increasing mechanism, and the fourth motor is connected to the infrared probe through an electrical signal.

[0012] The fourth motor outputs torque according to the electrical signal of the infrared probe, and transmits it to the three-stage transmission wheel group through the bevel gear group. As the fourth motor continues to output torque, the three-stage transmission wheel group sequentially transmits torque to the three-stage resistance increasing mechanism, thereby increasing the resistance of the heating resistor coil at the corresponding position and increasing the heating rate per unit time.

[0013] Furthermore, the three-stage transmission wheel group includes a mounting seat, a transmission shaft, a primary pulley, a secondary pulley and a tertiary pulley. The mounting seat is fixedly connected to the outer shell, the transmission shaft is rotatably connected to the mounting seat, the transmission shaft is transmission-connected to the bevel gear group, the primary pulley, the secondary pulley and the tertiary pulley, the primary pulley, the secondary pulley and the tertiary pulley are all transmission-connected, the primary pulley, the secondary pulley and the tertiary pulley are all transmission-connected to the three-stage resistance increasing mechanism, and the secondary pulley and the tertiary pulley have the same structure as the primary pulley.

[0014] The transmission shaft is transmitted through the bevel gear set, and the transmission shaft drives the primary pulley, the secondary pulley, and the tertiary pulley to transmit torque to the three-stage resistance increasing mechanism. As the transmission shaft continues to rotate, since the primary pulley, the secondary pulley, and the tertiary pulley have the same structure and their sizes are reduced proportionally, the transmission ratio with the three-stage resistance increasing mechanism increases successively, and the primary pulley, the secondary pulley, and the tertiary pulley break through the elastic buckle successively and no longer transmit torque.

[0015] Furthermore, the first-stage pulley includes an outer gear ring, a limit plate, a sliding seat, a spring head, a limit buckle, an inner arc turntable and an outer ring slide. The outer gear ring is transmission-connected to the third-stage resistance increasing mechanism, the limit plate and the sliding seat are fixedly connected to the outer gear ring, the spring head is slidingly connected to the sliding seat, the spring head is fixedly connected to the limit buckle, the inner arc turntable is transmission-connected to the transmission shaft, an inner arc groove is provided on the inner arc turntable, the inner arc groove contacts the spring head, and the outer gear ring is slidingly connected to the outer ring slide.

[0016] The transmission shaft outputs torque to the inner arc turntable. The inner arc groove of the inner arc turntable presses against the spring head, and drives the outer gear ring to rotate through the sliding seat fixed on the outer gear ring, thereby transmitting torque to the three-stage resistance increasing mechanism. As the multi-stage contraction rings on the three-stage resistance increasing mechanism press against the heating resistor ring in sequence, the outer gear ring is stuck. As the transmission shaft continues to output torque, the inner arc groove of the inner arc turntable pushes the limit buckle to break through the limit plate. The outer ring edge of the inner arc turntable contacts the spring head, and the inner arc turntable no longer pushes the spring head, thereby avoiding damage to the outer gear ring.

[0017] Furthermore, the three-stage resistance increasing mechanism includes a primary contraction ring, a secondary contraction ring and a tertiary contraction ring. The primary contraction ring, the secondary contraction ring and the tertiary contraction ring are all fixedly connected to the outer shell. The primary contraction ring is meshed with the tooth surface of the outer ring gear, the secondary contraction ring is meshed with the tooth surface of the secondary sliding wheel, and the tertiary contraction ring is meshed with the tooth surface of the tertiary sliding wheel. The secondary contraction ring and the tertiary contraction ring have the same structure as the primary contraction ring.

[0018] The primary shrink ring, the secondary shrink ring, and the tertiary shrink ring have the same structure, and their sizes are reduced proportionally in sequence. The outer gear ring transmits torque to the primary shrink ring through tooth surface meshing. The primary shrink ring first presses against the heating resistor ring, and then bites the heating resistor ring through the primary shrink ring. The primary shrink ring is connected in series with the heating resistor ring to increase the heating efficiency. As the secondary shrink ring and the tertiary shrink ring shrink the heating resistor ring in sequence, the heating efficiency increases step by step.

[0019] Furthermore, the primary contraction ring includes a tooth plate, an outer tube and an iris mechanism. The outer tube is fixedly connected to the outer shell, the tooth plate is rotationally connected to the outer tube, the tooth plate is transmission-connected to the outer gear ring and the iris mechanism, and the iris mechanism is slidingly connected to the heating resistor ring.

[0020] The torque is transmitted to the tooth plate through the outer tooth ring, and the tooth plate drives the iris mechanism similar to the iris mechanism to contract and press against the heating resistor coil. The iris mechanism is connected in series with the heating resistor coil, which increases the resistance value in turn and increases the heating efficiency.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention designs a stirring mechanism. In infrared microwave detection, bubbles exist on the rubber, which will produce color difference. The inclination degree of the inclined threaded rod is adjusted to adjust the stirring density of the stirring raw materials and eliminate the bubbles in the rubber raw materials; the present invention designs a heating mechanism. The infrared probe detects that the raw materials are heated unevenly in certain areas, and sends an electrical signal to the second motor and the third motor. The second motor and the third motor output torque to the first gear ring and the second gear ring through the first gear head and the second gear head respectively. The first gear ring and the second gear ring rotate to drive the two groups of variable resistance mechanisms to slide to different positions on the heating resistor ring. The resistance value of the heating resistor ring located at the two groups of variable resistance mechanisms is changed according to the electrical signal, so that the heating rate of the section is changed, and then the area with uneven heating is heated to make it heated evenly; the present invention designs a variable resistance Mechanism, the fourth motor outputs torque, and the transmission shaft drives the inner arc turntable through the bevel gear set. The inner arc groove of the inner arc turntable drives the outer gear ring to rotate by pressing against the spring head, and transmits torque to the three-stage resistance increasing mechanism. As the multi-stage shrinking rings on the three-stage resistance increasing mechanism press against the heating resistor ring in turn, the outer gear ring is stuck, and the transmission shaft continues to output torque. The inner arc groove of the inner arc turntable pushes the limit buckle to break through the limit plate, and the outer ring edge of the inner arc turntable contacts the spring head. The inner arc turntable no longer pushes the spring head to avoid damage to the outer gear ring. The outer gear ring transmits torque to the tooth plate, driving the iris mechanism to contract and press against the heating resistor ring. The iris mechanism is connected in series with the heating resistor ring to increase the heating efficiency. The present invention can automatically detect the stirring condition of the rubber raw material, and adjust the mechanism according to the rubber condition to ensure that the rubber raw material does not contain bubbles and is heated evenly, thereby ensuring the mechanical properties and sealing properties of the rubber raw material.

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] The present invention provides a technical solution:

[0031] like Figure 1As shown, the processing equipment includes a top cover 1, a first motor 2, an infrared probe 3, a stirring mechanism 4, a chassis 5 and a heating mechanism 6. The top cover 1 is fixedly connected to the first motor 2, the infrared probe 3, the stirring mechanism 4 and the heating mechanism 6. The output end of the first motor 2 is transmission-connected to the stirring mechanism 4. The infrared probe 3 is connected to the stirring mechanism 4 and the heating mechanism 6 through electrical signals. The chassis 5 is fixedly connected to the heating mechanism 6.

[0032] The stirring device is used to stir rubber raw materials so that they can achieve mechanical properties and sealing properties that meet standards. The rubber raw materials are injected into the device through the top cover 1. The first motor 2 outputs torque to the stirring mechanism 4 to stir the raw materials. The heating mechanism 6 provides heat for the whole machine to heat the raw materials. During the heating process, due to the fact that the raw materials are not fully mixed, the non-volatile gas is wrapped in the rubber product, or the rubber is heated unevenly, which will affect the quality of rubber stirring. The infrared probe 3 performs infrared detection on the rubber being stirred. In the infrared microwave detection, the presence of bubbles on the rubber will produce color difference, and the unevenly heated areas can be detected. The infrared probe 3 sends electrical signals to the stirring mechanism 4 and the heating mechanism 6. The stirring mechanism 4 continuously adjusts the stirring density of the stirring raw materials to eliminate bubbles. The heating mechanism 6 adjusts the temperature of the interval heating to make the rubber raw materials evenly heated.

[0033] like Figure 2 As shown, the stirring mechanism 4 includes a main shaft 41, a top plate 42, a first gear 43 and an inclined threaded rod 44, the top plate 42 is fixedly connected to the top cover 1, the main shaft 41 is rotatably connected to the top plate 42, the main shaft 41 is transmission-connected to the output end of the first motor 2, the first gear 43 is fixedly connected to the main shaft 41, and two groups of inclined threaded rods 44 are provided, the two groups of inclined threaded rods 44 are meshed with the tooth surfaces of the first gear 43, the two groups of inclined threaded rods 44 are rotatably connected to the top plate 42, and the inclined threaded rods 44 are connected to the infrared probe 3 through electrical signals.

[0034] The output torque of the first motor 2 is transmitted to the inclined threaded rod 44 through the main shaft 41 and the first gear 43, driving the inclined threaded rod 44 to rotate on the top plate 42 to stir the rubber raw material. According to the electrical signal of the infrared probe 3, the inclination degree of the inclined threaded rod 44 is adjusted, thereby adjusting the stirring density of the stirred raw material and eliminating bubbles on the raw material.

[0035] like Figure 3As shown, the heating mechanism 6 includes a bottom cylinder 61, a second motor 62, a third motor 63, a first gear ring 64, a second gear ring 65, a stirring cylinder 66, a heating resistor 67, a sliding rod 68 and a variable resistance mechanism 69, the stirring cylinder 66 is fixedly connected to the top cover 1 and the bottom cylinder 61, the first gear ring 64 and the second gear ring 65 are slidably connected to the bottom cylinder 61, the second motor 62 and the third motor 63 are fixedly connected to the bottom cylinder 61, the output end of the second motor 62 is provided with a first gear head 621, and the output end of the third motor 63 is provided with a third gear head 624. Two tooth heads 631, the first tooth head 621 is meshed with the tooth surface of the first gear ring 64, the second tooth head 631 is meshed with the tooth surface of the second gear ring 65, the sliding rod 68 and the variable resistance mechanism 69 are each provided with two groups, the two groups of sliding rods 68 are fixedly connected to the first gear ring 64 and the second gear ring 65, the variable resistance mechanism 69 is slidably connected to the heating resistor ring 67 and the sliding rod 68, the heating resistor ring 67 is fixedly connected to the mixing drum 66, the second motor 62, the third motor 63, and the variable resistance mechanism 69 are all connected to the infrared probe 3 through electrical signals.

[0036] The heating mechanism 6 heats the rubber raw material by energizing the heating resistor coil 67 fixed on the mixing drum 66 to generate heat. When the infrared probe 3 detects that there are areas of raw material that are heated unevenly, an electrical signal is sent to the second motor 62 and the third motor 63. The second motor 62 and the third motor 63 output torque to the first gear ring 64 and the second gear ring 65 through the first gear head 621 and the second gear head 631 respectively. The first gear ring 64 and the second gear ring 65 rotate to drive the two groups of variable resistance mechanisms 69 to slide to different positions on the heating resistor coil 67. The resistance value of the heating resistor coil 67 located at the two groups of variable resistance mechanisms 69 is changed according to the electrical signal, so that the heating rate of the section is changed, and then the area with uneven heating is heated to make it heated evenly.

[0037] like Figure 4 As shown, the resistance variable mechanism 69 includes a housing 691, a fourth motor 692, a bevel gear set 693, a three-stage transmission wheel set 694 and a three-stage resistance increasing mechanism 695. The housing 691 is slidingly connected to the sliding rod 68, the fourth motor 692, the three-stage transmission wheel set 694 and the three-stage resistance increasing mechanism 695 are all fixedly connected to the housing 691, the output end of the fourth motor 692 is transmission-connected to the bevel gear set 693, the three-stage transmission wheel set 694 is transmission-connected to the bevel gear set 693 and the three-stage resistance increasing mechanism 695, and the fourth motor 692 is connected to the infrared probe 3 via an electrical signal.

[0038] The fourth motor 692 outputs torque according to the electrical signal of the infrared probe 3, and transmits it to the three-stage transmission wheel group 694 through the bevel gear group 693. As the fourth motor 692 continues to output torque, the three-stage transmission wheel group 694 sequentially transmits the torque to the three-stage resistance increasing mechanism 695, so that the resistance value of the heating resistor coil 67 at the corresponding position increases, and the heating rate per unit time increases.

[0039] like Figure 5As shown, the three-stage transmission wheel group 694 includes a mounting seat 6941, a transmission shaft 6942, a primary pulley 6943, a secondary pulley 6944 and a tertiary pulley 6945. The mounting seat 6941 is fixedly connected to the housing 691, the transmission shaft 6942 is rotatably connected to the mounting seat 6941, the transmission shaft 6942 is transmission-connected to the bevel gear group 693, the primary pulley 6943, the secondary pulley 6944 and the tertiary pulley 6945, the primary pulley 6943, the secondary pulley 6944 and the tertiary pulley 6945 are transmission-connected to the three-stage resistance increasing mechanism 695, and the secondary pulley 6944 and the tertiary pulley 6945 have the same structure as the primary pulley 6943.

[0040] The transmission shaft 6942 is transmitted through the bevel gear set 693, and the transmission shaft 6942 drives the primary pulley 6943, the secondary pulley 6944, and the tertiary pulley 6945 to transmit the torque to the tertiary resistance increasing mechanism 695. As the transmission shaft 6942 continues to rotate, since the primary pulley 6943, the secondary pulley 6944, and the tertiary pulley 6945 have the same structure and their sizes are reduced proportionally, the transmission ratio with the tertiary resistance increasing mechanism 695 increases successively, and the primary pulley 6943, the secondary pulley 6944, and the tertiary pulley 6945 successively break through the elastic buckle and no longer transmit torque.

[0041] like Figure 5 , Figure 6 As shown, the first-stage pulley 6943 includes an outer gear ring 69431, a limit plate 69432, a sliding seat 69433, a spring head 69434, a limit buckle 69435, an inner arc turntable 69436 and an outer ring slide 69437. The outer gear ring 69431 is transmission connected to the third-stage resistance increasing mechanism 695, the limit plate 69432 and the sliding seat 69433 are fixedly connected to the outer gear ring 69431, the spring head 69434 is slidingly connected to the sliding seat 69433, the spring head 69434 is fixedly connected to the limit buckle 69435, the inner arc turntable 69436 is transmission connected to the transmission shaft 6942, the inner arc turntable 69436 is provided with an inner arc groove 694361, the inner arc groove 694361 is in contact with the spring head 69434, and the outer gear ring 69431 is slidingly connected to the outer ring slide 69437.

[0042] The transmission shaft 6942 outputs torque to the inner arc turntable 69436. The inner arc groove 694361 of the inner arc turntable 69436 presses against the spring head 69434, and drives the outer gear ring 69431 to rotate through the sliding seat 69433 fixed on the outer gear ring 69431, thereby transmitting torque to the three-stage resistance increasing mechanism 695. As the multi-stage contraction rings on the three-stage resistance increasing mechanism 695 press against the heating resistor ring 67 in turn, the outer gear ring 69431 is stuck. As the transmission shaft 6942 continues to output torque, the inner arc groove 694361 of the inner arc turntable 69436 pushes the limit buckle 69435 to break through the limit plate 69432. The outer ring edge of the inner arc turntable 69436 contacts the spring head 69434, and the inner arc turntable 69436 no longer pushes the spring head 69434, thereby avoiding damage to the outer gear ring 69431.

[0043] like Figure 4 As shown, the three-stage resistance increasing mechanism 695 includes a primary contraction ring 6951, a secondary contraction ring 6952 and a tertiary contraction ring 6953. The primary contraction ring 6951, the secondary contraction ring 6952 and the tertiary contraction ring 6953 are all fixedly connected to the outer shell 691. The primary contraction ring 6951 is meshed with the tooth surface of the outer gear ring 69431, the secondary contraction ring 6952 is meshed with the tooth surface of the secondary pulley 6944, and the tertiary contraction ring 6953 is meshed with the tooth surface of the tertiary pulley 6945. The secondary contraction ring 6952 and the tertiary contraction ring 6953 have the same structure as the primary contraction ring 6951.

[0044] The primary shrink ring 6951, the secondary shrink ring 6952, and the tertiary shrink ring 6953 have the same structure, and their sizes are reduced proportionally in sequence. The outer tooth ring 69431 transmits torque to the primary shrink ring 6951 through the engagement of the tooth surface. The primary shrink ring 6951 first presses against the heating resistor ring 67, and then bites the heating resistor ring 67 through the primary shrink ring 6951. The primary shrink ring 6951 is connected in series with the heating resistor ring 67 to increase the heating efficiency of the primary shrink ring 6951. As the secondary shrink ring 6952 and the tertiary shrink ring 6953 shrink the heating resistor ring 67 in sequence, the heating efficiency increases step by step.

[0045] like Figure 4 As shown, the first-stage contraction ring 6951 includes a tooth plate 69511, an outer tube 69512 and an iris mechanism 69513. The outer tube 69512 is fixedly connected to the outer shell 691, the tooth plate 69511 is rotatably connected to the outer tube 69512, the tooth plate 69511 is transmission-connected to the outer gear ring 69431 and the iris mechanism 69513, and the iris mechanism 69513 is slidably connected to the heating resistor ring 67.

[0046] The torque is transmitted to the tooth plate 69511 through the outer tooth ring 69431, and the iris mechanism 69513 is contracted and pressed against the heating resistor coil 67 through the tooth plate 69511. The iris mechanism 69513 is connected in series with the heating resistor coil 67, which increases the resistance value and the heating efficiency in turn.

[0047] The working principle of the present invention is as follows: the stirring device stirs the rubber raw material to achieve mechanical properties and sealing properties that meet the standards. The first motor 2 outputs torque to the stirring mechanism 4 to stir the raw material. The heating mechanism 6 provides heat for the whole machine to heat the raw material. The infrared probe 3 performs infrared detection on the rubber being stirred. In the infrared microwave detection, bubbles exist on the rubber, which will produce color difference. All areas with uneven heating can be detected. The infrared probe 3 sends electrical signals to the stirring mechanism 4 and the heating mechanism 6. The stirring mechanism 4 continuously adjusts the stirring density of the stirred raw material to eliminate bubbles. The infrared probe 3 sends electrical signals to the second motor 62 and the third motor 63 to drive the two groups of variable resistance mechanisms 69 to slide to different positions on the heating resistor ring 67. The fourth motor 692 outputs torque, which is transmitted through the bevel gear set 693 to the transmission shaft 6942 to drive the inner arc rotating disk 69436. The inner arc groove 694361 of the inner arc rotating disk 69436 drives the outer gear ring 69431 to rotate by resisting the spring head 69434, and transmits torque to the three-stage resistance increasing mechanism 695. As the three-stage resistance increasing mechanism 695 rotates, the outer gear ring 69431 rotates and the outer gear ring 69431 rotates. The multi-stage contraction rings on the resistance mechanism 695 press against the heating resistor ring 67 in turn, the outer gear ring 69431 is stuck, the transmission shaft 6942 continuously outputs torque, the inner arc groove 694361 of the inner arc rotating disk 69436 pushes the limit buckle 69435 to break through the limit plate 69432, the outer ring edge of the inner arc rotating disk 69436 contacts the spring head 69434, the inner arc rotating disk 69436 no longer pushes the spring head 69434, avoiding damage to the outer gear ring 69431, and the outer gear ring 69431 transmits torque to the gear plate 69511. The iris mechanism 69513 is driven to contract and press against the heating resistor coil 67. The iris mechanism 69513 is connected in series with the heating resistor coil 67 to increase the resistance value in turn and increase the heating efficiency. The primary pulley 6943, the secondary pulley 6944 and the tertiary pulley 6945 transmit the torque to the tertiary resistance increasing mechanism 695. The primary pulley 6943, the secondary pulley 6944 and the tertiary pulley 6945 break through the elastic buckle in turn and no longer transmit the torque.
