Detailed Description

The invention will now be described in further detail with reference to the drawings and preferred embodiments. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

As shown in fig. 1 and 2, an upper bracket 3 is installed above a heat dissipation hole 2 of a cabinet body 1, the upper bracket 3 is two brackets arranged in parallel, an upper rotating shaft 4 is rotatably installed in the middle of the upper bracket 3, a rubber ring is sleeved at a position where the upper rotating shaft 4 contacts with the upper bracket 3, and the rubber ring is used for increasing the friction force between the upper rotating shaft 4 and the upper bracket 3 when the upper rotating shaft 4 rotates, so that the design is to prevent the excessive release of a filter screen caused by the over-fast rotation of the upper rotating shaft 4 and the complete attachment of the filter screen and the heat dissipation hole 2; the filter screen can be purchased from the market directly or purchased and cut by itself, then the filter screen is wound on the upper rotating shaft 4, taking the commercially available packaged filter screen customized according to the specification as an example, a hard paper cylinder is arranged in the middle of the packaged filter screen, the hard paper cylinder is sleeved on the upper rotating shaft 4, the upper rotating shaft 4 and the hard paper cylinder are fixed by a clamping piece or a tensioning piece, then one end of the filter screen is pulled to enable the filter screen to cover the heat dissipation holes 2 and be attached to the heat dissipation holes 2, and finally the filter screen penetrates through an outlet 8 arranged below the heat dissipation holes 2 to be fixed with the lower rotating shaft 6; in order to prevent the filter screen from being pulled too straight and the two sides from turning and tilting, guide grooves or guide wheels for pressing the filter screen can be arranged on the two sides where the filter screen is laid, and the design of the part is not shown in the figure.

The filter screen and the lower rotating shaft 6 are fixed by using clamping parts, bonding parts or tensioning parts as well, the lower rotating shaft 6 is installed on a lower support 5, the lower support 5 is installed on an installation frame 9, the installation frame 9 is welded or fixed on the outer side of the cabinet body through bolts, the installation frame 9 is of a metal frame structure, the lower support 5 and the upper support 3 are the same and are composed of two supports which are arranged in parallel, a bearing is installed on the lower support 5, the lower rotating shaft 6 is installed in the bearing, a driven wheel is welded at one end of the lower rotating shaft 6, a belt is sleeved on the driven wheel and is connected with a driving wheel fixedly installed on an output shaft of the motor 7, the motor 7 is installed on a bearing support 9 which is far away from the cabinet body 1, and the motor 7 is installed on the far away side from the; the belt transmission is a common transmission, and when the volume of the packaged filter screen is large, the transmission part can be replaced by gear transmission or gear set transmission.

On the outside of the cabinet 1, at the position where the filter screen comes out from the outlet 8, an encoder 11 is installed, which is a device for compiling and converting signals (such as bit stream) or data into a signal form for communication, transmission and storage. Its indicating value is only relevant with measuring originated and final position, and is irrelevant with measuring intermediate process, and the encoder of this application is the encoder of taking the pivot, and fixed mounting has the gyro wheel in encoder 11's pivot, and the outer lane laminating of gyro wheel sets up on the filter screen that stretches out from export 8 to drive the gyro wheel rotation by the filter screen, the gyro wheel is one to provide the parameter that the filter screen gos forward for the encoder, and two come the gyro wheel top on the filter screen, reduce the friction of filter screen and export 8 departments.

Lower carriage 5, encoder 11 and motor 7 fixed mounting are on mounting bracket 9, shell 10 has been suit in the outside of mounting bracket 9, shell 10 is arranged in protecting the equipment in mounting bracket 9, be located the positive below of the cabinet body when the mounting bracket, like the position of figure 1, shell 10 can be processed into one side and have open-ended rectangle metal casing, become a step form after the suit is on mounting bracket 9 when shell 10, the staff can step on and operate, in order to prevent that the personnel from stepping on and can fall, the upper surface of shell 10 has the non-skid protrusion.

The start and stop of the motor 7 are respectively completed by a timer and an encoder, the timer controls the start of the motor 7, the encoder is responsible for the stop of the motor 7, the control method is very simple, the timer is a countdown controller, a timer switch is pressed down after the filter screen and the lower rotating shaft 6 are fixed, the timer starts to count down, when the countdown reaches '0', the countdown controller gives a signal to the motor 7 or the controller for controlling the start of the motor 7, and the motor 7 is started; the motor 7 is started to drive the lower rotating shaft 6 to rotate, the filter screen is recovered, the encoder 11 is driven to work when the filter screen is recovered and rotated, when the encoder 11 rotates enough circles, a signal is given to the motor 7 or a controller for controlling the motor 7 to stop, the motor 7 stops, the timer counts down again after the motor 7 stops, and the process is repeated; the count-down is quantitative, represents the time that the filter screen can be used, and the number of turns that encoder 11 rotated is obtained by simple computational formula, and if the filter screen length that covers on louvre 2 needed 15cm, the gyro wheel girth that uses on encoder 11 was 5cm, 15 ÷ 5 ═ 3 circles.

The circuit diagram is omitted in the figure because the circuit diagram is an existing simple circuit, the most common one for controlling the operation of a certain electric appliance by using a countdown controller is an alarm clock, the encoder 11 is originally a signal generator, and the circuit that is not common is used for controlling the start and stop of the electric appliance by using a signal, so the figure is omitted.
