DETAILED DESCRIPTION

[0028] See also Figure 1-Figure 10 In an embodiment of the present invention, a winding chuck driving device includes a winding chuck 101, and a torque motor is installed at one end of the winding chuck 101, and the torque motor includes a shell 1; a driving shaft 102 is rotatably arranged in the shell 1, and the driving shaft 102 is assembled and connected with the winding chuck 101 away from the shell 1. Preferably, when the driving shaft 102 rotates, the driving shaft 102 drives the winding chuck 101 to rotate, so that the winding chuck 101 does not need to be driven by a transmission setting of a motor, a reducer and a pulley, and avoids the changes in belt tightness after long-term operation of the belt transmission, which affects the rotation accuracy of the winding chuck 101 and requires frequent replacement of the belt.

[0029] Please refer to Figure 3 Preferably, the torque motor also includes a torque motor stator 2, a torque motor rotor 3, a rotor connecting bolt 5, and a stator connecting bolt 6; the drive shaft 102 is installed at the center position of the housing 1 through a bearing group, the torque motor stator 2 is installed on the housing 1 through the stator connecting bolt 6, and the torque motor rotor 3 is fixedly connected to the drive shaft 102 through the rotor connecting bolt 5, so that the torque motor rotor 3 rotates synchronously with the drive shaft 102, and an encoder 7 is installed at one end of the drive shaft 102 away from the winding chuck 101. The encoder 7 can be set to feedback the rotation speed of the torque motor in real time to achieve closed-loop control of the torque motor.

[0030] During specific use, when the torque motor directly drives the winding chuck 101 to rotate and output through the drive shaft 102, the torque motor will generate a large amount of heat. In order to dissipate the heat and ensure its stable operation, preferably, a water-cooling jacket 4 is installed on the periphery of the outer shell 1. The water-cooling jacket 4 is arranged on the periphery of the torque motor stator 2, and there is a gap between the two, so that circulating water can be passed between the water-cooling jacket 4 and the torque motor stator 2 through an external pipeline, and then the torque motor is cooled by the circulating water, avoiding the problem that the heat generated by the torque motor cannot be dissipated in time, resulting in overheating of the torque motor, reducing its efficiency, accelerating the aging of internal components of the torque motor, and increasing the failure rate.

[0031] In actual use, if the temperature of the surrounding environment is low and the humidity is high, water vapor in the environment can easily condense into water droplets on the outer surface of the water-cooling jacket 4. When a large number of condensation droplets gather, dripping problems will occur. When the dripping condensation droplets come into contact with the surface of other equipment, sputtering will occur. The dripping condensation droplets can easily cause electrical equipment around the torque motor to short-circuit. Preferably, a collection component is provided on the outer sliding portion of the water-cooling jacket 4, and a transmission component is provided on the outer transmission portion of the collection component. The end of the transmission component away from the collection component is connected to the drive shaft 102 for transmission. When the drive shaft 102 rotates, the collection component is driven to move back and forth on the water-cooling jacket 4 through the transmission drive component. When the collection component moves, the condensation droplets generated on the surface of the water-cooling jacket 4 can be collected, thereby avoiding the influence of the condensation droplets thereon.

[0032] Please refer to Figure 1-Figure 7 Preferably, the collecting assembly includes a mounting ring 20; the mounting ring 20 is sleeved on the periphery of the water-cooling jacket 4, the side of the mounting ring 20 close to the water-cooling jacket 4 is installed with an absorbent cotton 14, the side of the absorbent cotton 14 away from the mounting ring 20 is slidably fitted with the periphery of the water-cooling jacket 4, the periphery of the mounting ring 20 is fixedly provided with a first fixing seat 23 and a second fixing seat 24, the first fixing seat 23 is transmission-connected to the transmission assembly, the second fixing seat 24 is arranged on a side away from the first fixing seat 23, and a round rod is slidably provided on the second fixing seat 24, through By setting the first fixed seat 23, the second fixed seat 24, the transmission assembly, and the round rod, the mounting ring 20 is restricted. In this way, when the transmission assembly drives the mounting ring 20 to reciprocate on the water-cooling jacket 4, the mounting ring 20 will not have the problem of deviation to one side. During use, when the transmission assembly rotates, the mounting ring 20 is reciprocated on the water-cooling jacket 4 through the first fixed seat 23. The movement of the mounting ring 20 drives the absorbent cotton 14 to move, and the movement of the absorbent cotton 14 absorbs the water droplets appearing on the water-cooling jacket 4.

[0033] Further, preferably, the transmission assembly includes a transmission rod 8; two groups of first rings 9 are rotatably provided on the transmission rod 8, the two groups of first rings 9 are respectively arranged on both sides of the water-cooling jacket 4, and the first rings 9 are sleeved on the periphery of the outer shell 1, a connecting plate 25 is fixedly provided between the first rings 9 and the outer shell 1, a transmission disk 12 is fixedly provided on the end of the transmission rod 8 away from the first rings 9, the transmission disk 12 corresponds to the driving shaft 102 and is transmission-connected by a belt, the transmission rod 8 is transmission-connected to the first fixed seat 23, a reciprocating thread is provided on the periphery of the transmission rod 8 between the two groups of first rings 9, and a protrusion that slidably cooperates with the reciprocating thread is provided in the first fixed seat 23, so that when the driving shaft 102 rotates, the driving shaft 102 drives the transmission disk 12 to rotate so that the transmission rod 8 rotates, and the rotation of the transmission rod 8 causes the mounting ring 20 to reciprocate on the water-cooling jacket 4 through the cooperation of the reciprocating thread and the protrusion, and then the water droplets on the surface of the water-cooling jacket 4 are collected by the absorbent cotton 14.

[0034] Please refer to Figure 5 , Figure 7 , Fig. 9 Preferably, arc plates 15 are slidably provided on both sides of the absorbent cotton 14, and grooves are provided on both sides of the mounting ring 20 for slidingly fitting with the arc plates 15. When the arc plates 15 move toward the water-cooling jacket 4 in the groove, the arc plates 15 completely and tightly slide and fit with the outer wall of the water-cooling jacket 4. Three groups of arc plates 15 are provided in a circular array along the center of the mounting ring 20. In the initial state, the arc plates 15 are located near the end of the groove away from the water-cooling jacket 4, that is, the three groups of arc plates 15 are separated and there is a gap between them and the water-cooling jacket 4. In this way, during the movement of the mounting ring 20, In the process, the arc plate 15 will not contact the surface of the water cooling jacket 4, resulting in the problem that the absorbent cotton 14 cannot absorb the water droplets on the surface of the water cooling jacket 4. When the three groups of arc plates 15 are moved to fit the water cooling jacket 4, the three groups of arc plates 15 form a circular ring structure with the same size as the absorbent cotton 14. At this time, the side of the arc plate 15 away from the water cooling jacket 4 slides and fits with the side of the mounting ring 20 close to the water cooling jacket 4, so that the arc plate 15 can move relative to the absorbent cotton 14 to squeeze out the water collected in the absorbent cotton 14, thereby realizing the cleaning function of the absorbent cotton 14.

[0035] Furthermore, preferably, a blocking block 16 is fixedly provided at the center of one end of the arc plate 15 away from the water-cooling jacket 4, a fixed block 17 is slidably connected to the top of the blocking block 16, a top plate 11 is fixedly provided on the top of the two groups of fixed blocks 17, and the two groups of fixed blocks 17 are synchronously moved through the top plate 11, the top plate 11 is arranged on the side of the mounting ring 20 away from the water-cooling jacket 4, and a spring is arranged between the top plate 11 and the mounting ring 20, a trigger block 13 slidably matched with the top plate 11 is fixedly provided on the side of the first circular ring 9 relative to the water-cooling jacket 4, and a mating groove 10 slidably matched with the blocking block 16 is provided on the outer shell 1.

[0036] It should be noted that: the bottom of the end of the trigger block 13 close to the water-cooling jacket 4 is provided with an inclined surface facing the water-cooling jacket 4, and the top height of the trigger block 13 is higher than the top height of the top plate 11, so that when the mounting ring 20 moves toward the trigger block 13, the trigger block 13 will slide with the top plate 11 through the action of the inclined surface, so that the top plate 11 is pushed toward the mounting ring 20, and the top of the absorbent cotton 14 is installed on the mounting ring 20 through a sliding fitting groove corresponding to the card block provided on the card block and the mounting ring 20, thereby facilitating the arc plate 15 to move toward the absorbent cotton 14 for extrusion, and also facilitating the replacement of the absorbent cotton 14.

[0037] Preferably, a conveying path 18 is provided in the mounting ring 20, and a notch 29 is provided at a position of the mounting ring 20 corresponding to the blocking block 16, the notch 29 is connected to the conveying path 18, the blocking block 16 and the notch 29 are slidably matched, a push rod 19 is provided between the two groups of blocking blocks 16, both ends of the push rod 19 slide into the two groups of blocking blocks 16, and a spring is provided between the push rod 19 and the inner wall of the blocking block 16, and a discharge pipe 28 is provided at the bottom of the conveying path 18.

[0038] When in use, in the initial state, the mounting ring 20 is in the middle of the water-cooling jacket 4, the arc plate 15 is separated from the water-cooling jacket 4, the end of the blocking block 16 close to the mounting ring 20 corresponds to the bottom end of the fixing block 17, and the blocking block 16 cooperates with the upper section of the groove at this time, that is, the relative positions of the blocking block 16 and the fixing block 17 are limited; when the drive shaft 102 rotates, the transmission disc 12 is driven to rotate, and then the transmission rod 8 is rotated, and the transmission rod 8 rotates through the first fixing seat 23 to make the mounting ring 20 reciprocate on the water-cooling jacket 4, first let the mounting ring 20 move to the upper side of the water-cooling jacket 4, when the mounting ring 20 moves to When the water-cooling jacket 4 is connected to the shell 1, the trigger block 13 causes the top plate 11 to move toward the mounting ring 20 to a state in which the mounting ring 20 is fitted through the inclined surface. When the top plate 11 moves toward the water-cooling jacket 4, the top plate 11 pushes the fixing block 17 to move, thereby pushing the blocking block 16 to move to a position adapted to the matching groove 10. The movement of the blocking block 16 pushes the arc plate 15 to move and fit closely to the water-cooling jacket 4. At this time, a plurality of groups of arc plates 15 are matched, and the opposite end of the blocking block 16 is adapted to the notch 29, and the blocking block 16 and the fixing block 17 can slide relative to each other. At this time, a group of arc plates 15 and The side wall of the shell 1 is fitted, and then when the transmission rod 8 continues to rotate, the mounting ring 20 will continue to move a certain distance in the original moving direction, and one set of arc plates 15 is in a state of moving relative to the other set of arc plates 15 under the resistance of the shell 1, so that the two sets of arc plates 15 squeeze the absorbent cotton 14, and a set of blocking blocks 16 moves into the notch 29, so that the conveying path 18 is gradually blocked with the movement of one set of arc plates 15, avoiding the problem of water overflow caused by the conveying path 18 not being blocked, and the water inside the squeezed absorbent cotton 14 will enter the conveying path 18; when the two sets of arc plates 15 are completely After the paired absorbent cottons 14 are squeezed to discharge the water inside them, the mounting ring 20 moves toward the other end of the water-cooling jacket 4 with the cooperation of the transmission rod 8 and the first fixed seat 23, and then the blocking block 16 moves and resets under the action of the top rod 19 and its corresponding spring. When the blocking block 16 moves and resets, the top plate 11 moves and resets under the action of the corresponding spring, thereby separating the arc plate 15 from the water-cooling jacket 4, and the absorbent cotton 14 also deforms and resets, continuing to collect the condensate beads on the water-cooling jacket 4, and the water squeezed into the conveying channel 18 will flow to the bottom of the conveying channel 18 and then be discharged through the discharge pipe 28.

[0039] Please refer to Figure 8Preferably, a sealing strip 26 is fixedly provided at one end of the arc plate 15, and a sealing groove 27 is provided at the other end of the arc plate 15. The sealing strips 26 and the sealing grooves 27 are arranged to correspond to each other between the two adjacent groups of arc plates 15. When the sealing strips 26 and the sealing grooves 27 are adapted, the sealing between the two adjacent groups of arc plates 15 is improved, and the problem of water on the absorbent cotton 14 being sprayed out through the gap between the two adjacent groups of arc plates 15 when the two groups of arc plates 15 are relatively close to each other and move and squeeze the absorbent cotton 14 is avoided.

[0040] Please refer to Fig.10 Preferably, an arc groove 22 is provided on one side of the arc plate 15 close to the absorbent cotton 14, and the arc groove 22 is symmetrically arranged along the center of the arc plate 15. A vertical groove 21 connected to the arc groove 22 is provided at the center of one side of the arc plate 15 close to the absorbent cotton 14. After the arc plate 15 moves toward the water-cooling jacket 4 and fits thereto, the top height of the vertical groove 21 is higher than the height of the absorbent cotton 14. In this way, when the arc plate 15 moves toward the absorbent cotton 14 and squeezes the absorbent cotton 14, a part of the water contained in the absorbent cotton 14 will be transported to the vertical groove 21 through the guiding effect of the arc groove 22 under the pressure of the arc plate 15 squeezing the absorbent cotton 14, and then transported to the conveying channel 18 through the top of the vertical groove 21, thereby improving the conveying efficiency of the water squeezed out of the absorbent cotton 14 and avoiding the problem that the water on the absorbent cotton 14 cannot be transported to the conveying channel 18 in time, resulting in the possible overflow of water from between the water-cooling jacket 4 and the arc plate 15.
