Description

Technical Field

[0001] This application relates to the technical field of cleaning equipment, and particularly to a driving and positioning mechanism and a dehydration device. Background Art

[0002] Artificial sericulture is a method of obtaining mulberry silk by artificially controlling the reproduction and growth process of silkworms, mainly including steps such as selecting good varieties, raising seedlings, feed management, and disease prevention. During the growth process of silkworms, it is necessary to regularly carry out cleaning and proper control of temperature and humidity to promote the healthy growth of silkworms and the production of cocoons. Industrial sericulture uses large-scale sericulture utensils such as sericulture frames and carriers, as well as automated feed feeding, temperature and humidity control, and transfer operations for silkworms of different ages, replacing the original small workshop sericulture mode, improving the sericulture efficiency, and reducing the labor intensity.

[0003] Among them, the sericulture frame is the main utensil for supporting silkworms to feed and grow. When the scale of industrial sericulture is very large, the daily usage of sericulture frames will also reach several thousand to tens of thousands. In order to avoid cross-contamination affecting the growth and development of silkworms, the used sericulture frames need to be cleaned and dehydrated before being used again. If a drying line is used for dehydration, the energy consumption is high, and the dehydration efficiency is low and the floor area is large, which cannot meet the needs of factory use. The dehydration device has a high dehydration efficiency and a small floor area. Compared with the traditional warm air drying, it saves more drying time and energy consumption, and has become a more widespread choice.

[0004] However, during the use of the dehydration device, when the motor speed is too high and the rotation speed is too fast, there is easily a problem of inaccurate positioning, which is not convenient for taking and placing the sericulture frames. Utility Model Content

It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present application.

[0034] In addition, the terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, the meaning of "a plurality of" and "several" is two or more, unless otherwise specifically defined.

[0035] It should be noted that the structures, ratios, sizes, etc. shown in the drawings of this specification are only used to cooperate with the content disclosed in the specification for those familiar with this technology to understand and read, and are not used to limit the implementation conditions of the present application. Therefore, they do not have technical substance significance. Any modification of the structure, change of the ratio relationship, or adjustment of the size, without affecting the effects that the present application can produce and the purposes that can be achieved, should still fall within the scope covered by the technical content disclosed in the present application.

[0036] As shown in the figure, an embodiment of the present utility model provides a driving and positioning mechanism, including: a driving wheel 1, a driving power source 2, a positioning wheel 3, a positioning power source 4, and a clutch 5.

[0037] The driving wheel 1 and the positioning wheel 3 are respectively fixedly connected to a rotating shaft.

[0038] The driving power source 2 is power-connected to the driving wheel 1.

[0039] The positioning power source 4 is power-connected or disconnected from the positioning wheel 3 through the clutch 5.

[0040] The present application provides a driving and positioning mechanism, including: a driving wheel 1, a driving power source 2, a positioning wheel 3, a positioning power source 4, and a clutch 5. The driving wheel 1 and the positioning wheel 3 are respectively fixedly connected to a rotating shaft; the driving power source 2 is power-connected to the driving wheel 1; the positioning power source 4 is power-connected or disconnected from the positioning wheel 3 through the clutch 5. For the driving and positioning mechanism provided by the present application, the rotating shaft is driven to rotate through the cooperation of the driving power source 2 and the driving wheel 1. At the same time, the positioning power source 4 and the positioning wheel 3 are provided, and whether the positioning power source 4 is connected to the positioning wheel 3 is controlled through the clutch 5, so that when the rotation of the rotating shaft stops, it can accurately stay at the target position. Then, the rotating cylinder connected to the rotating shaft can accurately stay at the target position, the positioning accuracy is improved to within 2 mm, there is no impact, the service life of the equipment is greatly extended, and the failure rate is also greatly reduced.

[0041] During this process, the driving power source 2 can maintain high power, and the reduction ratio of the driving wheel 1 can be reduced, and the dehydration speed can be increased, so that the dehydration effect is better, the manufacturing cost is lower, and there is no need to reduce the speed through a frequency converter to achieve positioning, avoiding the problem that the driving torque is too small to drive the rotating cylinder.

[0042] Specifically, when the driving power source 2 drives the rotating shaft to rotate for dehydration, keeping the positioning power source 4 and the positioning wheel 3 disconnected can avoid damaging the positioning power source 4 during high-speed operation. When it is necessary to stop and position, the positioning power source 4 is power-connected to the positioning wheel 3. At this time, the power of the positioning power source 4 is transmitted to the rotating shaft, and the driving power source 2 stops outputting power at this time. Relying on the positioning power source 4 to drive the positioning wheel 3 to rotate, the rotating shaft is accurately stopped at the target position.

[0043] Since the positioning power source 4 only works when the rotating shaft needs to stop and does not need to output high power, it can be positioned at a higher frequency, the output torque is stable, and it rotates at a low speed, so as to accurately position. Using the positioning power source 4 can also avoid the problems of large impact force and easy deformation and damage of the positioning pin when forcibly correcting with a positioning cylinder. When the positioning power source 4 drives, the driving power source 2 can rotate at a low speed following it without being damaged.

[0044] The clutch 5 used to realize this function can use commercially available standard parts in the art. When connected, it locks with the positioning wheel 3 of the positioning power source 4, and disengages from the positioning wheel 3 of the positioning power source 4 when released.

[0045] Preferably, the driving power source 2 and the driving wheel 1, or the positioning power source 4 and the positioning wheel 3, are respectively power-connected through any one of a transmission belt, a transmission chain, or a transmission gear.

[0046] Preferably, the driving power source 2 and the driving wheel 1 are power-connected through a transmission belt;

[0047] The positioning power source 4 and the positioning wheel 3 are power-connected through a transmission chain.

[0048] The power connection between the driving power source 2 and the driving wheel 1 can be achieved by any one of a transmission belt, a transmission chain or transmission gears; the power connection between the positioning power source 4 and the positioning wheel 3 can also be achieved by any one of a transmission belt, a transmission chain or transmission gears.

[0049] More preferably, the driving power source 2 and the driving wheel 1 are power-connected through a transmission belt, while the positioning power source 4 and the positioning wheel 3 are power-connected through a transmission chain.

[0050] Preferably, the driving power source 2 is a motor; the positioning power source 4 is a reduction motor.

[0051] The driving power source 2 is preferably a motor, and any ordinary motor can be used as long as the output power meets the requirements of dehydration. The positioning power source 4 is preferably a reduction motor, and its low-speed movement is used to ensure the positioning accuracy and it is not easy to damage the positioning parts.

[0052] A dehydration device drives the rotating shaft 6 by using the driving and positioning mechanism described in any one of the above items, and the rotating shaft 6 drives the rotating cylinder to rotate for dehydration.

[0053] The present application also provides a dehydration device that drives the rotating shaft 6 by using the above driving and positioning mechanism, and the rotating shaft 6 drives the rotating cylinder to rotate for dehydration. It can not only ensure the rotation speed of the rotating cylinder and the drying efficiency, but also accurately position when stopped, so that the rotating cylinder stops at the target position, which is convenient for loading and unloading.

[0054] Preferably, at least one rotating cylinder 7 is provided on the outer periphery of the rotating shaft 6, and a feeding mechanism 8 and a discharging mechanism 9 are further included.

[0055] Preferably, at least one rotating cylinder 7 is provided on the outer periphery of the rotating shaft 6, and a feeding mechanism 8 and a discharging mechanism 9 are further included. The feeding mechanism 8 is used to feed the stacked silkworm frames to be dehydrated into the rotating cylinder 7, and the discharging mechanism 9 is used to send out the stacked silkworm frames after dehydration. The feeding station of the feeding mechanism 8 and the discharging station of the discharging mechanism 9 are in different positions and will not interfere with each other.

[0056] Preferably, at least three rotating cylinders 7 are provided on the outer periphery of the rotating shaft 6, and the rotating cylinders 7 are circumferentially and evenly distributed around the rotating shaft 6.

[0057] More preferably, at least three rotating cylinders 7 are provided on the outer periphery of the rotating shaft 6, and the rotating cylinders 7 are circumferentially evenly distributed around the rotating shaft 6, which can simultaneously meet the dehydration of at least three stacks of silkworm frames. The single - time processing capacity is large, and it has the characteristics of high dehydration rate, uniform dehydration effect, large quantity, short working beat, high efficiency, etc., saving a large amount of labor costs. And it makes full use of the circumferential area occupied during rotation, and tries to increase the number of stacks of silkworm frames that can be dehydrated simultaneously under the condition of unchanged area.

[0058] In a dehydration process, the feeding mechanism 8 feeds the stack of silkworm frames to be dehydrated into the rotating cylinder 7. The driving power source 2 drives the rotating cylinder 7 to rotate by a certain angle, and successively feeds multiple stacks of silkworm frames to fill each rotating cylinder 7. Then the driving power source 2 drives the rotating cylinder 7 to rotate at a high speed along with the rotating shaft 6 to realize the centrifugal dehydration of the stack of silkworm frames. After dehydration, the discharging mechanism 9 successively takes out the stack of silkworm frames in each rotating cylinder 7 for discharging to complete one dehydration.
