Detailed Description

The following detailed description of embodiments of the present invention is made with reference to the accompanying drawings.

The utility model discloses a filter box main part 1 of scribing machine coolant liquid, there is horizontal first baffle 2 in the main part 1, first baffle 2 divides main part 1 cavity into upper chamber and lower chamber, be fixed with vertical second baffle 3 in the middle of the lower chamber, second baffle 3 divides the lower chamber into left chamber 4 and right chamber 5, there is a filter screen 6 in left chamber 4 and the right chamber 5, the filter screen 6 front end downward sloping, there is step hole 7 with filter screen 6 one-to-one on the first baffle 2, the upper end diameter of step hole 7 is greater than the lower extreme diameter, there is vertical montant 8 on the filter screen 6, the montant 8 upper end extends upwards and runs through the last side wall of main part 1 through step hole 7, montant 8 can reciprocate, there is the plectane 9 that corresponds to step hole 7 on the montant 8, plectane 9 moves down can block step hole 7 below it, only have a step hole 7 to supply the coolant liquid to pass through in the same time; there is the feed inlet on 1 posterior lateral plate of main part, and 1 lower extreme of main part has the liquid outlet, and 1 preceding curb plate lower extreme of main part has the discharge gate 10 with filter screen 6 one-to-one.

In order to realize the up-and-down movement of the vertical rod 8, the upper end of the vertical rod 8 penetrates through the upper side plate of the main body 1 and is arranged on the upper side of the main body 1, an annular bulge is arranged at the upper end of the vertical rod 8, and a pressure spring is connected between the annular bulge and the main body 1.

In order to realize that only one step hole 7 supplies the coolant liquid to pass through in the same time, 1 rear side of main part be fixed with the casing 11 of level form, the connecting rod 12 of level form has been placed in the casing 11, connecting rod 12 can only the back-and-forth movement in 11 cavitys of casing, be connected with a plurality of pressure springs between connecting rod 12 and the 11 posterior lateral plates of casing, both ends are fixed with the pin 13 with filter screen 6 one-to-one about connecting rod 12, pin 13 runs through 1 posterior lateral plate of main part and arranges the 1 intracavity in main part, pin 13 front end is the wedge structure, filter screen 6 can promote pin 13 successively through the wedge structure.

It is worth noting that the discharge port 10 is inclined, and an end cover is screwed on the discharge port 10; the space in the cavity of the shell 11 can only allow the connecting rod 12 to move back and forth, and the peripheral edge of the filter screen 6 is in contact with the main body 1 or the second partition plate 3.

For convenience of explanation, it is assumed that in an initial state, as shown in fig. 1, the rear end of the left filter screen 6 is located below the connecting rod 12, the rear end of the right filter screen 6 is located at the upper end of the connecting rod 12, at this time, the left stepped hole 7 is in a blocking state, and the right stepped hole 7 is in an open state; when the cooling device is used, cooling liquid passes through the right chamber 5, impurities in the cooling liquid are gradually accumulated at the upper end of the filter screen 6 in the right chamber 5, after a period of time, the impurities on the filter screen 6 on the right side are increased, the filter screen 6 on the right side moves downwards under the action of gravity, when the filter screen 6 on the right side passes through the pin 13, the pin 13 is driven by the filter screen 6 to push the connecting rod 12 to move backwards, meanwhile, the filter screen 6 on the left side moves upwards under the action of the pressure spring on the vertical rod 8 on the filter screen, at the same time, the stepped hole 7 on the right side is blocked, the stepped hole 7 on the left side is opened, the cooling liquid enters the left chamber 4 through the stepped hole 7 on the left side, so far, the switching action of the two filter screens 6 is completed, an operator only needs to open the discharge hole 10 on the right side to discharge the impurities on the filter screen 6 in the right chamber 5, at the moment, the filter screen 6 on the right side has the tendency of moving upwards under the action of the pressure spring on the upper end of the vertical rod 8 on the filter screen, but is prevented from moving upwards by the presence of the rear pin 13 and can only move upwards again while waiting for the left screen 6 to move downwards.

The utility model discloses the structure is ingenious, can clear up the plug on the filter screen 6 under the circumstances of not shutting down, reduces the number of times of shutting down, is favorable to improving the work efficiency of scribing machine, simple structure, easily realizes that the practicality is strong.
