Abstract
The utility model relates to a vacuum disc on a forming wheel for producing a labyrinth drip irrigation belt. The vacuum disc on the forming wheel for the labyrinth drip irrigation belt comprises an outer cover, an inner cover, a friction ring and a vacuum disc gland, wherein, the friction ring is fixed into the inner ring of the outer cover through the vacuum disc gland; the outer cover is a hollow disc; a step is formed on the end surface of one end of the outer cover; the inner cover is a concave hollow disc; the concave surface of the inner cover is opposite to the step surface of the outer cover; the inner hole of the inner cover is clamped in the step surface of the outer cover; the outer cover and the inner cover are connected together through bolts; an air chamber is formed by the concave surface of the inner cover and the outer cover; an arc-shaped through groove is formed on the outer wall of the concave end surface of the inner cover; and an air groove is formed on the inner side of the arc-shaped groove and communicated with the air chamber. When the vacuum disc works, only the inner cover is in contact with a plastic seal disc on the forming wheel, and when the vacuum disc is abraded, and only the inner cover is needed to be replaced, so as to reduce the production loss and further reduce the production cost of the drip irrigation belt.
Description
Technical field:
The utility model relates to a kind of production equipment of agricultural water-saving irrigation equipment, the vacuum pan when being specially adapted to the production of labyrinth type drip irrigation tape on the used briquetting roller.
Background technology:
At present, agricultural water-saving irrigation uses side seam formula labyrinth drip irrigating belt all by the briquetting roller vacuum adsorption molding, and the quality of briquetting roller vacuum directly influences the moulding of drip irrigation zone labyrinth flow-path.Existing molding wheel for drip irrigation belt is formed by forming disk, left and right sides cooler pan, middle spacer ring, axle, vacuum pan and with left and right sides cooler pan and ring for the sealing liquid, wherein vacuum pan is made up of vacuum pan enclosing cover, inner cap, dead turn, vacuum pan gland, enclosing cover and inner cap are columnar disk, inner cap is relative with enclosing cover to be assemblied among the enclosing cover and to form air chamber, inner cap cylindrical and enclosing cover inwall tight fit link together by bolt, have one section arc gap corresponding with several U-lags of inner cap inner face on the inner cap excircle.Inner cap forms air chamber with the inner chamber of enclosing cover and is communicated with the pore of briquetting roller by arc gap and U type groove, the end face of vacuum pan and the plastic seal dish on the briquetting roller during briquetting roller rotary work, the vavuum pump that connects by the vacuum pan other end is evacuated the briquetting roller shaping area, require briquetting roller that very high vacuum will be arranged during the production drip irrigation zone, could guarantee that like this drip irrigation zone labyrinth flow-path moulding is full.Because the plastic seal dish on this vacuum pan and the briquetting roller is by friction sealed, friction for a long time, make vacuum pan wear and tear, the sealing of briquetting roller reduces and influences vacuum, in order to guarantee to produce qualified drip irrigation zone, just needs to change vacuum pan, the inner cap of this vacuum pan and enclosing cover all rub with the plastic seal dish, therefore inner cap and enclosing cover all need to change, and this just causes very big waste, thereby make the production cost of drip irrigation zone increase.
Summary of the invention:
The purpose of this utility model provides the vacuum pan on a kind of molding wheel for drip irrigation belt, and the vacuum pan that it has well solved present use needs the problem of integral replacing when scrapping because of wearing and tearing.
The technical solution of the utility model is: the vacuum pan on this molding wheel for drip irrigation belt is by enclosing cover, inner cap, dead turn, the vacuum pan gland is formed, dead turn is fixed in the inner ring of enclosing cover by the vacuum pan gland, enclosing cover is the disk of hollow, on the one end end face ladder step is arranged, the ladder step is provided with seal groove, O-ring seal is arranged in the seal groove, inner cap is the hollow disc of spill, the outside diameter of inner cap and enclosing cover is identical, the concave surface of inner cap is relative with the step surface of enclosing cover, the endoporus of inner cap is stuck on the step surface of enclosing cover, by bolt enclosing cover and inner cap are linked together, inner cap concave surface and enclosing cover form an air chamber, and the groove of one section arc is arranged on the inner cap spill end face outer wall, and the deep-slotted chip breaker inboard is provided with air drain and air chamber is communicated with.The other end of inner cap and the plastic seal dish on the briquetting roller are friction sealed, when vacuum pan weares and teares, only need to change inner cap, and enclosing cover and miscellaneous part can continue to use.
Above-mentioned vacuum pan can cover outside with the outward flange of inner cap opposing end faces and establish a seal groove, and O-ring seal is set in seal groove, strengthens the sealing between the exterior and interior cover, thereby further improves the sealing property of air chamber.
Above-mentioned vacuum pan can be established a seal groove between the outer wall of inner cap spill end face and arc-shaped slot, O-ring seal is set in seal groove.
The length of the arc-shaped slot that covers in the above-mentioned vacuum pan vacuum pan is 1/4th of the pairing reference circle of arc-shaped slot.
The beneficial effects of the utility model are because this vacuum pan the time has only inner cap to contact with plastic seal dish on the briquetting roller in work, when vacuum pan weares and teares, only need to change inner cap, enclosing cover and miscellaneous part can continue to use, needed high vacuum when having guaranteed labyrinth type drip irrigation tape production, reduce the production loss, further reduced the production cost of drip irrigation zone.
Description of drawings:
Be further described below in conjunction with accompanying drawing:
Fig. 1 is the cutaway view of embodiment 1
Fig. 2 is the cutaway view of Fig. 1
The specific embodiment
Referring to figs. 1 through 2, embodiment 1 described vacuum pan is mainly by enclosing cover 1, inner cap 2, dead turn 3, vacuum pan gland 4 is formed, dead turn 3 is fixed in the inner ring of enclosing cover by vacuum pan gland 4, enclosing cover 1 is the disk of hollow, on the one end end face ladder step is arranged, the ladder step is provided with seal groove, O-ring seal 5 is arranged in the seal groove, inner cap 2 is the hollow disc of spill, inner cap 2 is identical with the outside diameter of enclosing cover 1, the concave surface of inner cap 2 is relative with the step surface of enclosing cover 1, the endoporus of inner cap 2 is stuck on the step surface of enclosing cover 1, inner cap 2 concave surfaces and enclosing cover 1 form an air chamber 8, and the groove 7 of one section arc is arranged on the inner cap spill end face outer wall, and the deep-slotted chip breaker inboard is provided with air drain 6 and air chamber 8 is communicated with.The other end of inner cap and the plastic seal dish on the briquetting roller are friction sealed.
As the further improvement of above-mentioned vacuum pan, cover with the outward flange of inner cap opposing end faces outside and to establish a seal groove, in seal groove, place O-ring seal, strengthening the sealing between the exterior and interior cover, thereby further improve the sealing property of air chamber.
