Description
Technical field
The present invention relates to a kind of filter that is used to filter dust, the invention still further relates to a kind of assembly method of filter.
Background technology
At present, filter of the prior art, it is well-known being included in the filter core excessively that pleat is crossed on the shell.At the filter core of crossing of ring-like filter, be the ring of a sealing and inside and outside between connect plastic sheath.Known filter is not satisfied; Because bonding filter core excessively is difficult; Owing to be difficult to coat entire contact surface to adhesive, unnecessary adhesive was dispersed on the filter core and second-rate being connected, and all can cause seepage; Dust can pass through leakages like this, rather than is filtered the device filtration.
Summary of the invention
The objective of the invention is to avoid deficiency of the prior art and a kind of filter and assembly method thereof be provided, its cross filter core and the shell bonding quality good, do not have unnecessary adhesive to be dispersed on the filter core.
The object of the invention is realized through following technical scheme:
A kind of filter is provided, and this filter comprises: a shell, shell have in one week and an outer circumferential walls, have first and second ring frame to extend internally from outer mural margin on the outer circumferential walls, and in outer wall week formation tunnel; Annular has a large amount of foldings and makes the filter core of crossing of closed loop shape, and this crosses filter core has a periphery and endoporus, crosses filter core and is positioned in the outer circumferential walls of shell through adhesive.
Wherein, be bonded with the nylon net in the hole of described filter core excessively.
A kind of above-mentioned filter assembly method is provided; Outer circumferential walls with shell is positioned on the rolling clamp earlier; And the tunnel coated with adhesive on outer circumferential walls, will cross filter core again and be positioned in the outer circumferential walls, make its rotation; Cross filter core along radial expansion, until the adhesive of crossing on the interior week that the filter core periphery touches outer circumferential walls.
Wherein, the in-core hole is filtered in the nylon net insertion of coated with adhesive, rotate and inserted the nylon net that filters the in-core hole, make the nylon wire cover be connected in the surface of filtering the in-core hole.
Filter core excessively of the present invention and shell bonding quality are good, do not have unnecessary adhesive to be dispersed on the filter core, can not cause the dust seepage.

The specific embodiment
Be described in further detail below in conjunction with the accompanying drawing specific embodiments of the invention.
In Fig. 1 to 10, filter of the present invention comprises a filter housing 1 and crosses filter core 2 with circular folding.The shell 1 of this filter is one cylindrical, and by an appropriate plastic material manufacturing.This filter housing 1 is made up of with coaxial 4 of the center rings that are connected a columniform outer wall 3, and coaxial connection center ring 4 is radially to throw support or 5 of spokes with several to be connected with outer wall 3.The axially interior outstanding ring frame 6 and 7 that extends of the U-shape cross section top edge of outer wall 3 forms a tunnel.This coaxial center ring 4 is with radial spoke 5 and encircle frame side by side at outer wall 3.Cylindrical outer wall 3, center ring 4 is to produce one by the plastics forming technique manufacturing with spoke 5.
The filter core 2 that folded of annular has radial fold to be arranged in one in the periphery 19 of crossing filter core and centre bore between week 18.The periphery 19 of crossing filter core is positioned in the cylindrical outer wall 3 and week goes up the tunnel, and sticks on outer wall on 3 interior weeks with adhesive.The centre bore of filter is lined up consistent with shell center ring 4.Is a nylon net 8 at center ring with being filtered what surrounded in in-core week 18.Can nylon net 8 and shell center ring 4 be pasted on filtration in-core week 18 in the layer of adhesive on the nylon net 8 20.
External toroidal ring 17 is positioned at top at the bottom of the centre bore of nylon net 8 and filter.
Figure 11 to 18 has represented the method for a filter assembling.This device is by 21,22 compositions of two rolling clamps.First rolling clamp 21 comprises a rotation driving main shaft 23 and C type chuck 24, and C type chuck 24 is as the cylindrical outer wall 3 that is fixed with center ring 4 when assembling.Main shaft 23 is to be driven by the motor (not shown).Second rolling clamp 22 comprises a hollow spindle 25, and an end of hollow spindle 25 is C type cups 26.Second rolling clamp 22 is rotary but is not connected to driver.Second rolling clamp 22 can move forward and backward along its rotating shaft (arrow indicated direction 27).The face that touches 30 boths on contact-making surface on the chuck 24 29 and the corresponding C of being connected on shape cup 26 have high friction surface coating layer separately.When second rolling clamp 22 moves, contact-making surface 29 and 30 engages, shown in Figure 13-14.Second rolling clamp 22 can make first rolling clamp with identical speed rotation.
Outside C type cup 26 shells, be second chuck 31.On the rotating shaft 32 in second chuck 31 is mounted on the hollow ingot 25.Rotating shaft 32 is connected with interior hollow ingot 25, so that it and second rolling clamp 22 together rotate, but still can move independently along the direction of the represented rotating shaft of arrow 27.Backboard chuck 33 on second chuck 31 is to be fixed on anchor clamps 22.
The first step of filter assembling is having the cylindrical outer wall 3 of a center ring 4 to be put into the chuck 24 on first rolling clamp 21, crossing filter core 2 and then be placed on second chuck 31 on second rolling clamp 22.Next, motor rotary clamp 21 and layer of adhesive 34 can be deposited on the interior week in tunnel on the cylindrical outer wall 3.In the centrifugal force that first rolling clamp 21 is produced can be distributed in adhesive equably on all tunnels.Second rolling clamp 22 moves and is connected with first rolling clamp 21 along its rotating shaft then, and is shown in figure 13.Frictional force between 29 and 30 causes second rolling clamp 22 rotating with the speed consistent with anchor clamps 21.The initial position of second chuck 31 makes cylinder cross filter core 2 and is put within the outer wall 3.Rotating shaft 32 is recalled second chuck 31 along turning cylinder, and is shown in figure 14.Crossing filter core 2 is to stay original position through backboard 33, recalled filter core 2 when second chuck 31 and under centrifugal forces affect, be radially expanded, so that its periphery 19 touches the adhesive coating on week in the outer wall 3.21,22 of these anchor clamps keep present position and rotation, so that adhesive parches.Second anchor clamps 22 move apart anchor clamps 21 like Figure 15 then.
Shown in figure 16 in following step, nylon net 8 inserts and filters the in-core hole and be filtered in-core week 18 encirclements.Ring 17 is installed in the 3rd chuck 35.When first rolling clamp 21 in rotation, the 3rd chuck 35 be used for slotting ring circle 17 go into nylon jacket 8 with cross filter core 2 interior all 18 in.Still rotate and be dispersed in second layer adhesive 20 on the nylon net 8 at Figure 17 anchor clamps, see through the hole of passing through on the net and touched cartridge surface 18 and center ring 4 and ring 17.Nested grid 8 adhesive 20 that helps to distribute equably has been filter core inner surface 18 and ring 17 and center ring 4.Adhesive 20 will filter in-core week 18 and nylon net 8 bonds together.Move when adhesive has parched chuck 35, Figure 18 removes in the equipment of filter assembling.
In a word; The above-mentioned preferred implementation though the present invention has given an example should be explained, though those skilled in the art can carry out various variations and remodeling; Only if such variation and remodeling have departed from scope of the present invention, otherwise all should be included in protection scope of the present invention.
