Description

Technical Field

[0001] The utility model relates to the technical field of atomizer main shaft devices, in particular to a paste resin latex drying atomizer main shaft. Background Art

[0002] The nebulizer is used to atomize the test solution. It is an important part of the atomization system, and its performance has a significant impact on the precision of the measurement and chemical interference. Therefore, the nebulizer is required to have stable spray, small and uniform droplets, and high atomization efficiency. It is also called jet atomization, which is based on the Venturi injection principle and uses compressed air to form a high-speed airflow through a small pipe. The negative pressure generated drives the liquid or other fluids to be sprayed onto the obstruction. Under high-speed impact, the droplets splash around and become mist particles that are ejected from the outlet pipe.

[0003] At present, when the main shaft of the dry atomizer is in use, the oil is easily leaked from the gap connection when the main shaft is guiding the flow, resulting in a waste of resources. At the same time, it is easy to shake during its processing and installation, causing deviation, increasing the wear of the shaft and reducing the service life of the main shaft.

[0004] In view of this, we propose a paste resin latex drying atomizer spindle. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a paste resin latex drying atomizer main shaft.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The utility model installs the main shaft of the dry atomizer vertically during use, and the lower dynamic labyrinth seal is installed on the outer wall of the shaft. When the shaft is driven, the lower dynamic labyrinth seal rotates with the shaft. Due to gravity, the second bearing is lubricated. When the oil drops, it drops to the inclined surface to be cut off, and dynamic bottom sealing is performed. The upper and lower labyrinth seals are used to prevent oil from flowing between the upper and lower oil tanks. Due to the influence of centrifugation, the inclined surface of the lower dynamic labyrinth seal is streamlined and does not contact the shaft to prevent oil loss. The internal gear coupling is installed at the top to offset the deviation in processing when the main shaft is used, so as to improve the convenience of using the main shaft of the dry atomizer and prevent oil loss.

[0016] 2. The utility model eliminates the axial movement of the bearing by installing butterfly spring 2 in cooperation with the spring pad. At the same time, the butterfly spring 2 is distributed in a circle and pressed on the top of the bearing to fix its main shaft. The side adjustment flange makes it easy to adjust the shaft up and down. The outside of the bearing support is threaded, and the adjustment bearing can rise and fall in unison, which is convenient for slight adjustment when the shaft is worn, thereby increasing its service life. The guide bearing 1 maintains the forward position of the shaft to reduce jitter deviation. The guide bearing 1 is spherical in shape with a certain gap inside, and the spherical surface can be fine-tuned according to the micro-swing of the shaft. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0024] See also Figures 1 to 4 , the utility model provides a technical solution:

[0025] A paste resin latex drying atomizer main shaft comprises a drying atomizer main shaft body 1, a protective component 2 is installed at the top of the drying atomizer main shaft body 1, an upper deep groove bearing 26 is arranged on the inner side of the drying atomizer main shaft body 1, a connecting shaft 12 is installed on the left side of the drying atomizer main shaft body 1, a reinforcing ring sleeve 15 is installed on the outer side of the connecting shaft 12, a lower dynamic labyrinth seal 14 is installed on the outer side of the drying atomizer main shaft body 1, an installation cavity 11 is opened at the bottom of the lower dynamic labyrinth seal 14, a lower deep groove bearing 13 is installed on the side of the lower dynamic labyrinth seal 14, a butterfly spring 111 is installed on the right side of the drying atomizer main shaft body 1, an output connection end 18 is installed on the right side of the drying atomizer main shaft body 1, a spring pad 16 is installed on the side of the butterfly spring 111, and a guide bearing 110 is installed on the side of the spring pad 16.

[0026] It should be added that, during the use of the dry atomizer main shaft body 1, the dry atomizer main shaft body 1 is installed vertically, and the lower dynamic labyrinth seal 14 is installed on the outer wall of the shaft. When the shaft is driven, the lower dynamic labyrinth seal 14 rotates with the shaft. Due to gravity, the second bearing is lubricated. When the oil drops, it drops to the inclined surface for cutoff, and dynamic bottom sealing is performed. The upper and lower labyrinth seals are used to prevent oil from flowing between the upper and lower oil tanks. Due to the influence of centrifugation, the inclined surface of the lower dynamic labyrinth seal 14 is streamlined and does not contact the shaft to prevent oil loss. The internal gear coupling 22 is installed at the top to offset the deviation in processing when the main shaft is used, so as to improve the convenience of using the dry atomizer main shaft body 1 and prevent oil loss.

[0027] As a preferred embodiment of the present invention, a guide bearing seat 17 is installed on the side of the guide bearing 110, a spring seat 19 is installed on the side of the guide bearing seat 17, a resistance seat 29 is installed on the side of the spring seat 19, a buffer seat 210 is installed on the left side of the resistance seat 29, a buffer cavity 27 is opened inside the buffer seat 210, and a spring sheet 28 is installed inside the buffer cavity 27.

[0028] It is worth noting that by installing the butterfly spring 111 in cooperation with the spring washer 16, the axial movement of the bearing is eliminated. At the same time, the butterfly spring 111 is distributed in a circle and pressed on the top of the bearing to fix its main shaft. The side adjustment flange 25 makes it easy to adjust the shaft up and down. The outside of the bearing support is threaded, and the bearing can be adjusted to rise and fall in unison, so that the shaft can automatically return to the center when deviation occurs. At the same time, the concentricity during high-speed rotation is guaranteed, which is convenient for slight adjustment when the shaft is worn, thereby increasing its service life.

[0029] As a preferred embodiment of the present invention, an internal gear coupling 22 is installed on the side of the protective component 2, a side mounting cavity 23 is provided below the internal gear coupling 22, an adjusting flange 25 is installed on the side of the side mounting cavity 23, a mounting hole 24 is provided on the surface of the adjusting flange 25, and a protective pad 21 is provided below the adjusting flange 25.

[0030] During specific use, the forward position of the shaft is maintained by a guide bearing 110 to reduce jitter and deviation. The guide bearing 110 is spherical in shape with a certain gap inside, and the spherical surface can be fine-tuned according to the micro-swing of the shaft.

[0031] When the main shaft of the paste resin latex drying atomizer of the utility model is used, it first adopts the form of a vertically installed flexible shaft, wherein the upper deep groove bearing 26 and the lower deep groove bearing 13 are fixed on both sides of the main shaft as two fixed fulcrums at the same time, and the distance between the upper deep groove bearing 26 and the internal gear coupling 22 is smaller than the distance between the lower deep groove bearing 13 and the atomizing wheel position on the left side of the output connection end 18, and the fixed fulcrum (lower deep groove bearing 13) close to the atomizing wheel is far away from the atomizing wheel position and is cantilevered, so that the "automatic centering" effect is obvious when the main shaft rotates at high speed and vibration is reduced, the stability is relatively good, which is conducive to improving the atomization effect and service life.

[0032] In the use of the main shaft body 1 of the dry atomizer, the main shaft body 1 of the dry atomizer is installed vertically, and the lower dynamic labyrinth seal 14 is installed on the outer wall of the shaft. When the shaft is driven, the lower dynamic labyrinth seal 14 rotates with the shaft. Due to gravity, the second bearing is lubricated and then descends to play a sealing role to prevent oil from flowing out. When the oil descends, it descends to the inclined surface to be cut off, and dynamic bottom sealing is performed. The upper and lower labyrinth seals are used to prevent oil from flowing between the upper and lower oil tanks. Due to the influence of centrifugation, the inclined surface of the lower dynamic labyrinth seal 14 is streamlined and does not contact the shaft. The internal gear coupling 22 is installed at the top to offset the deviation in processing when the main shaft is used, so as to improve the use of the main shaft body 1 of the dry atomizer. In order to improve the convenience of use, the butterfly spring 111 is installed in cooperation with the spring washer 16 to eliminate the axial movement of the bearing. At the same time, the butterfly spring 111 is distributed in a circle and pressed on the top of the bearing to fix its main shaft. The side adjustment flange 25 makes it easy to adjust the shaft up and down. The outside of the bearing support is threaded, and the bearing can be adjusted to rise and fall in unison, so that it can automatically return to the center when the shaft deviates. At the same time, the concentricity during high-speed rotation is guaranteed, which is convenient for slight adjustment when the shaft is worn, thereby increasing its service life. The forward position of the shaft is maintained by the guide bearing 110 to reduce the deviation caused by shaking. The guide bearing 110 is spherical in shape with a certain gap inside, and the spherical surface can be fine-tuned according to the micro-swing of the shaft.

[0033] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
