Summary of the invention
The purpose of this utility model is to design a kind of screen cloth tensioning apparatus with elasticity tension, utilizes this device, can effectively control the elastic tension effect of vibratory equipment upper screen cloth.
The technical scheme that provides according to the utility model has arm-tie at the root of bolt, at the head of the bolt nut that is spirally connected, spring is arranged on bolt, and described spring is between described arm-tie and described nut.
Socket is used for the pressing plate and the seat board of retainer spring on described bolt, and described pressing plate and described seat board are between described arm-tie and described nut, and described spring is between described pressing plate and seat board.
On described pressing plate and the described seat board step is arranged all, described spring is located on the described step.The both sides of the edge up and down of described arm-tie are respectively to a side bending of nut, form first bending part at the upside of arm-tie, are formed for catching on second bending part of screen cloth at the downside of arm-tie.
Described bolt is positioned at the hole that is arranged on the screen drum wall, and the position corresponding to first bending part on the screen drum wall is provided with locating piece, and the position corresponding to second bending part on the screen drum wall is provided with bracing frame; Described first bending part is against on the locating piece, and described second bending part is against on the support frame as described above; Described seat board is attached on the described screen drum wall near the end face of arm-tie one side.The interplanar of the axis of described bolt and described screen drum wall intersects with sharp angle.
Installation method of the present utility model on vibratory equipment, during to the screen cloth tensioning, as long as with version of the present utility model, is installed on an end or two ends of tensioning screen cloth; Adjust screen cloth face one end or two ends and use the fastening bolt tensioning respectively, reach the effect of pretension up to the active force of spring, screen cloth tensioning intensity is moderate.When doing the screen cloth replacing, do not influence the serviceability of other member, do not influence the vibrating carrier complete machine, just can in time change.
In Foundry Production, the application of vibrating machine, vibratory equipment is a lot, as the swing crushing screening machine, and vibrating screen classifier, band sieves the separator conveyer of structure etc. in vibrating shakeout conveyer and the vibrating transportation, all can adopt the screen cloth tensioning apparatus of elasticity tension.This device helps the service life of screen cloth, more helps the maintenance and the replacing of screen cloth.In the development of vibrating machine, use extensive especially at present.
The utlity model has simple in structure, be easy to install characteristics such as supporting; can effectively protect the appropriate tensioning of screen cloth, in by sieve weight of material change procedure, make screen cloth under elasticity tension effect; can overcome rigid tensioning and cause flimsy shortcoming, guarantee the normal service life of screen cloth.
Description of drawings
Structural representation when Fig. 1 is the utility model use.
Fig. 2 is an application example of the present utility model.
The specific embodiment
As shown in the figure: the root at bolt 7 has arm-tie 3, at the head of bolt 7 nut 4 that is spirally connected, spring 1 is arranged on bolt 7, and described spring 1 is between described arm-tie 3 and described nut 4.Socket is used for the pressing plate 5 and seat board 2 of retainer spring 1 on described bolt 7, and described pressing plate 5 and described seat board 2 are between described arm-tie 3 and described nut 4, and described spring 1 is between described pressing plate 5 and seat board 2.On described pressing plate 5 and the described seat board 2 step is arranged all, described spring 1 is located on the described step.The both sides of the edge up and down of described arm-tie 3 are respectively to a side bending of nut 4, form first bending part 10 at the upside of arm-tie 3, are formed for catching on second bending part 11 of screen cloth 6 at the downside of arm-tie 3.
During use, described bolt 7 is positioned at the hole 13 that is arranged on the screen drum wall 8, and the position corresponding to first bending part 10 on screen drum wall 8 is provided with locating piece 9, and the position corresponding to second bending part 11 on screen drum wall 8 is provided with bracing frame 12; Described first bending part 10 is against on the locating piece 9, and described second bending part 11 is against on the support frame as described above 12; Described seat board 2 is attached on the described screen drum wall 8 near the end face of arm-tie 3 one sides.The interplanar of the axis of described bolt 7 and described screen drum wall 8 intersects with sharp angle.When fastening nut 4; pressing plate 5 continuous holddown springs 1; under the effect of the spring force of spring 1; bolt 7 can clockwise rotate around the contact point of first bending part 10 with locating piece 9, second bending part, 11 pulling screen clothes 6 is moved to the left, with screen cloth 6 tensions; because by spring 1 effect; therefore this pulling be flexible or claim soft, can hard draw screen cloth 6, screen cloth 6 is played a very good protection.
On the swing crushing screening machine or on other vibrosieve equipment, it is a plurality of to use this tensioning apparatus, the installation site can also can be used in the bilateral position of screen cloth 6 on the monolateral position of screen cloth 6.
When being applied to the Screening Network structure tensioning of swing crushing screening machine or other screening plant, on one side of screen cloth 6 or bilateral, utilize the adjusting of bolt 7 and nut 4, spring 1 is compressed in certain pretightning force, utilize the effect of elastic force, drive arm-tie 3 and make screen cloth 6 tensionings.When tensioning surplus when not being very big, adopt the single-side structural mode; When tensioning surplus big (with the relevant structure of screen mesh size), adopt the bilateral structure mode.
The utility model adopts the elastic tension apparatus of spring structure, utilizes the pretightning force of spring, makes compass screen surface be in the tight or title elasticity tension of a kind of soft drawn.Compass screen surface in screening material process, can carry out elasticity along with the variation of material loading capacity and change under the elastic vibration duty.Like this, improve the service life of screen cloth, correspondingly improved the service life of vibratory equipment.Fig. 1 is the enlarged drawing of A among Fig. 2 simultaneously.
