Description

Technical Field

[0001] The invention belongs to the technical field of couplings, in particular to a connecting device for a stirring shaft of a reaction kettle for producing coatings. Background Art

[0002] Paint mixer is one of the components of paint production equipment. It is a device used for mixing paint. Paint mixer can crush, disperse, emulsify and mix paint. It is a new type of high-efficiency mixing equipment with high-speed operation of the upper and lower teeth of the dispersion plate. It can strongly shear, impact, crush and disperse the materials at high speed to achieve the functions of rapid mixing, dissolving, dispersing and refining. It is an efficient equipment for mixing, dispersing and dissolving paint and other solids. At present, in the process of coating production and processing, the connection between the motor shaft and the stirring shaft is generally manually connected through couplings or flange connection bolts, which are tightened symmetrically and evenly. This connection method takes a long time to disassemble and assemble. In addition, when the motor shaft drives the stirring shaft to rotate and stir the coating, when stirring the water-based coating with hydroxyethyl cellulose (HEC), the cellulose molecules absorb water and swell during stirring and form a network structure with the water phase. The viscosity increases significantly with the extension of stirring time. In this way, the stirring shaft is subject to additional resistance, which will not match the rotation of the motor shaft, and the load on the motor shaft will increase. If the workers do not find and adjust it in time, the service life of the motor will be shortened over time, resulting in unstable connection. Summary of the invention

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0019] like Figures 1 to 8 As shown, the present invention provides a connecting device for a stirring shaft of a reactor for producing coatings, comprising a motor body 1, a top plate 11 is provided above the motor body 1, a U-shaped plate frame 12 is fitted and connected to the bottom end of the top plate 11, an electric cylinder 13 is fixedly connected between the top plate 11 and the U-shaped plate frame 12, two telescopic rods 14 are fixedly connected to the outer wall of the bottom end of the U-shaped plate frame 12, a bottom plate 15 is fixedly connected to the bottom end of the two telescopic rods 14, the bottom end of the bottom plate 15 is fixedly connected to the outer wall of the top end of the motor body 1, a stirring shaft body 3 is provided below the rotating shaft of the motor body 1, a dynamic torque sensor is fixedly connected to the stirring shaft body 3, and a connecting part 2 is provided between the motor body 1 and the stirring shaft body 3, the connecting part 2 includes a sleeve plate 1 21 fixedly connected to the rotating shaft of the motor body 1, and a sleeve plate 2 22 fixedly connected to the top end of the stirring shaft body 3, a rectangular card groove is opened in the inner wall of the bottom end of the sleeve plate 1 21, and a group of symmetrical elastic card connection structures are provided on the sleeve plate 22.

[0020] The above scheme is adopted: by starting the electric cylinder 13 on the top plate 11, the U-shaped plate frame 12, the bottom plate 15, the motor body 1 and the two telescopic rods 14 can be driven to move downward together. The existence of the two telescopic rods 14 will not cause obstruction due to the existence of the electric cylinder 13 when the sleeve plate 21 and the motor body 1 are passively moved upward, and the rod body will be directly retracted on the telescopic rod 14. When the sleeve plate 1 21 and the sleeve plate 2 22 are subsequently connected again, the electric cylinder 13 is required to move downward again at a certain distance at the original position, and the dynamic torque sensor installed on the stirring shaft body 3 will detect the change in torque value, indirectly reflecting the increase in stirring resistance caused by the increase in viscosity. At this time, the signal is transmitted to the control terminal, and then a start signal is sent to the two-way electric cylinder 28 to make it work. This is a prior art and will not be repeated in this article.

[0021] A group of symmetrical elastic snap-in structures each include an L-shaped rod 23 that is slidably connected to one end of the sleeve plate 22, a push plate 24 is fixedly connected to the rod body at one end of the L-shaped rod 23, a spring 25 is fixedly connected between the plate body at one end of the push plate 24 and the outer wall at one end of the sleeve plate 22, a clamping plate 26 that can be snapped with the inner wall of the rectangular slot is fixedly connected to the rod body at one end of the L-shaped rod 23 near the top, an arc angle groove 27 that is slidably connected to the L-shaped rod 23 is opened on the top of the sleeve plate 22, a two-way electric cylinder 28 is also fixedly connected to the plate body at one end of the push plate 24, a support plate frame 29 is fixedly connected to the outer wall of the two-way electric cylinder 28, and the push plate 24 can be slidably connected to the plate body of the support plate frame 29.

[0022] The above scheme is adopted: the operation of the bidirectional electric cylinder 28 causes its output end to drive the abutment plates 24 fixed at both ends to translate in opposite directions to each other, so that the spring 1 25 is deformed by force, and the L-shaped rod 23 that is passively squeezed in the sleeve plate 22 and the arc angle groove 27 to translate will synchronously drive the clamping plate 26 connected in the sleeve plate 1 21 to gradually disengage from the rectangular clamping groove, so as to quickly separate the connection parts.

[0023] The L-shaped rod 23 is also fixedly connected to an inclined hinge plate 230 on one end of the rod body near the top, and a horizontal hinge plate 231 is hinged on the other side plate body of the inclined hinge plate 230. A hinge rod 232 is fixedly connected to the central plate body of the horizontal hinge plate 231, and a rubber clamping rod 233 is fixedly connected to the rod body of the hinge rod 232. The rubber clamping rod 233 is provided with a vertical plate 234, and a vertical clamping groove 235 is opened in the vertical plate 234 to slide and clamp with the rubber clamping rod 233. The top groove of the vertical clamping groove 235 The shape of the opening matches and is clamped with the rubber clamp rod 233, and the notches at other positions are long rectangular grooves with a diameter larger than the diameter of the rubber clamp rod 233. A spring 236 is fixedly connected to the outer wall of the bottom end of the vertical plate 234, and the bottom end of the spring 236 is fixedly connected to the outer wall of the top end of the sleeve plate 22. An annular groove 237 is provided on the top of the sleeve plate 22, and two I-shaped rods 238 are fitted and rotatably connected in the inner wall of the annular groove 237. The top ends of the two I-shaped rods 238 are magnetically connected to the bottom end of the sleeve plate 1 21.

[0024] By adopting the above scheme: when the card plate 26 completely disengages from the inner wall of the rectangular card slot, the previously moved L-shaped rod 23 will synchronously drive the connected inclined hinge plate 230 to further tilt, so that it can drive the hinged horizontal hinge plate 231 to move downward, and the downwardly moved horizontal hinge plate 231 will drive the hinge rod 232 and the rubber card rod 233 to move downward synchronously. This process can press the rubber card rod 233 downward to disengage from the vertical card slot 235 provided in the vertical plate 234. Without the additional limit of the rubber card rod 233, the vertical plate 234 will be elastically reset under the drive of the second spring 236. The sleeve 21 is thus passively moved upward, and is connected with the outer wall of the bottom end of the sleeve 21 with impact force, thereby pushing up the sleeve 21, so that the L-shaped rod 23 and the clamping plate 26 are completely exposed, which is convenient for subsequent operations by the staff. After the sleeve 21 is passively moved upward, the I-shaped rod 238 will also be separated from it. The installation of the I-shaped rod 238 in the annular groove 237 can increase the connection stability point between the sleeve 21 and the sleeve 22 when they rotate together. Subsequently, by starting the electric cylinder 13, the sleeve 21 is indirectly driven to move downward in real time to press the vertical plate 234, and then it can be clamped and reset again.

[0025] A ball shaft 239 is movably connected to the outer wall of one end of the stop plate 24 near the top, and a pressure plate 240 is also movably connected to the ball shaft 239. A vertical shaft is fixedly connected to the inner wall of the pressure plate 240 near the top, and a rubber roller 241 is rotatably connected to the vertical shaft. A rotating rod 242 is rotatably connected to the lower half of the plate body of the pressure plate 240, and one end of the rotating rod 242 is fixedly connected to a polygonal support plate 243. One end of the polygonal support plate 243 is fixedly connected to the outer wall of one end of the sleeve plate 22, and the pressure plate 240 and the plate body of the polygonal support plate 243 are fixedly connected. A spring three 244 is fixedly connected to the intermediate joint, a roller groove 245 is opened on the outer wall of the sleeve plate 21, the rubber roller 241 and the inner wall of the roller groove 245 can fit and slide together, a protective sleeve 246 is slidably connected to the rotating shaft of the motor body 1, and connecting plates 247 are fixedly connected to the outer walls of both ends of the protective sleeve 246, and the top ends of the two connecting plates 247 are fixedly connected to the outer walls on both sides of the bottom end of the top plate 11, and a section of the plate body of the support frame 29 close to the top is fixedly connected to the outer wall of one side of the top end of the protective sleeve 246.

[0026] The above scheme is adopted: when the abutment plate 24 is passively moved, the pressure plate 240 is also pushed through the ball shaft 239, so that it is tilted in the opposite direction with the rotating rod 242 as the axis point. The tilting process will stretch the spring three 244 installed on the polygonal support plate 243, causing it to deform, thereby driving the rubber roller 241 to disengage from the roller groove 245 on the sleeve plate 21, releasing the connection between the motor body 1 and the stirring shaft body 3. When the sleeve plate 21 is passively rotated intermittently while moving down to reset the connection, it is necessary to manually restart the two-way electric cylinder 28 to retract the rod body, thereby driving the rubber roller 241 to be clamped into the annular groove 237 again for limiting work. The pressure plate 240 and the rubber roller 241 work together to limit and reinforce the connection point of the sleeve plate 21 without affecting the normal passive rotation of the sleeve plate 21.

[0027] It should be added that the spiral structure of the second spring 236 should be tightly wound around the third spring 244, so that when the vertical plate 234 pushes the first sleeve plate 21, the second spring 236 can fully support the force of the vertical plate 234 pushing the first sleeve plate 21 by its own elasticity; The rubber clamping rod 233 and the rubber roller 241 are both made of natural rubber, which has high elasticity and high wear resistance.

[0028] The working principle and use process of the present invention are as follows: when the coating is stirred by the stirring shaft body 3, the gradually becoming viscous coating will gradually generate greater resistance to the abutment plate 24 rotating with the stirring shaft body 3. At this time, the dynamic torque sensor installed on the stirring shaft body 3 will indirectly identify the viscosity of the coating in real time. When it reaches the load generated by the motor body 1 and the stirring shaft body 3, the bidirectional electric cylinder 28 installed on the support plate frame 29 will be automatically started, which has been described in detail above and will not be repeated here, so that it drives the abutment plates 24 fixed at both ends to translate in opposite directions to each other, so that the spring 1 25 is deformed by force, and the L that is passively squeezed in the sleeve plate 22 and the arc angle groove 27 for translation is automatically started. The L-shaped rod 23 will synchronously drive the card plate 26 connected to the sleeve plate 1 21 to gradually disengage from the rectangular card slot. When the card plate 26 completely disengages from the inner wall of the rectangular card slot, the previously moved L-shaped rod 23 will synchronously drive the connected inclined hinge plate 230 to further tilt at an angle, so that it can drive the hinged horizontal hinge plate 231 to move downward. This process can press the rubber card rod 233 to disengage from the vertical card slot 235 provided in the vertical plate 234. Without the additional limit of the rubber card rod 233, the vertical plate 234 will be elastically reset under the drive of the spring 236, thereby passively moving upward, and the sleeve plate 1 21 with impact force is pushed up, so that the L-shaped rod 23 and the card plate 26 are completely exposed, which is convenient for subsequent manual operation. In the above, the connection method between the first plate 21 and the second plate 22 is quick to operate, simple in structure, and low in cost. When the power does not match, the automatic separation process can be quickly performed to avoid the problem that the motor body 1 is subjected to long-term load and shortens the service life. When the abutment plate 24 is passively moved, the ball shaft 239 will push the pressure plate 240, causing it to tilt in the opposite direction with the rotating rod 242 as the axis point. The tilting process will stretch the spring 3 244 installed on the polygonal support plate 243, causing it to deform, thereby driving the rubber roller 241 to disengage from the roller groove 245 on the sleeve plate 21, releasing the connection between the motor body 1 and the stirring shaft body 3. The pressure plate 240 and the rubber roller 241 will jointly limit and reinforce the connection point of the sleeve plate 21 without affecting the normal passive rotation of the sleeve plate 21. In the above, the first layer of connection between the card plate 26 and the rectangular card slot, plus the second layer of connection between the annular groove 237 and the rubber roller 241, can ensure the stability of the connection while greatly improving the connection speed between the two shafts, avoiding manual operation and the need for manual observation of the production and processing process of the paint so that the stirring process can be adjusted in time.
