A kind of screw rod point glue pump
Technical field
This utility model relates to a kind of screw pump point glue distributor, is particularly suited for high-viscosity glue, containing pimpled rubber, moisture-curable glue, solder(ing) paste, it is desired to bubble-free a kind of accurate screw pump fluid distributing apparatus after some glue.
Background technology
The existing fluid method of salary distribution probably has two kinds: one is contact point glue, and another kind is contactless glue.Contactless glue is high to the requirement of glue, narrow application range, and equipment price is higher, unpicks and washes maintenance all inconveniences, and the glue content of injection is easily generated bubble, and surrounding such as temperature and wind speed are required height.Contact point glue is divided into again time pressure formula and screw.Time pressure formula contact point glue has the disadvantage that: first, in the case of air pressure is certain, in glue bucket glue quantity number and the viscosity of glue change over the concordance that all can affect glue point.Second, owing to carrying out some glue by the break-make of simple air pressure, the efficiency making this kind of some glue mode is low.3rd, due to the characteristic that glue is intrinsic, easily produce wire drawing.4th, want often to be adjusted ensureing concordance for dispensing glue to air pressure during some glue.5th, require that the distance between syringe needle with substrate is identical and close during some glue, owing to fixture or workpiece have deformation to be easy to scratch surface of the work.Current existing screw point glue equipment screw rod and O the most easily wear and tear, and substantially reduce the service life of equipment, and screw stator can wobble effects position for dispensing glue and size accuracy when glue.
Summary of the invention
In order to overcome the defect of existing screw spot gluing equipment, this utility model provides a kind of new screw spot gluing equipment to be not only able to realize putting glue accurately and is easy to maintaining and improves the life-span of equipment.
This utility model solves its technical problem and be the technical scheme is that a kind of screw rod point glue pump includes motor casing, in the bottom of motor casing, motor mount is set, motor is arranged on motor mount, the output revolving shaft of motor is connected with screw rod by shaft coupling, drive screw turns, the spiro tooth part of screw rod sets up separately puts stator, the side of stator arranges a glue feeding opening near thread top, glue feeding opening is connected with glue inlet tube road, top, glue inlet tube road arranges glue bucket, it is connected by joint, the bottom of cavity is arranged plastic hole and is connected by adaptor with syringe needle, between top and the cavity of screw rod thread, a sealing device is set.
Described screw rod point glue pump, wherein, arranges a shaft coupling between motor output shaft and screw rod.
Described screw rod point glue pump, wherein, there is a swivel nut stator lower end, is used for locking syringe needle.
Described screw rod point glue pump, wherein, described screw rod is wolfram steel.
Described screw rod point glue pump, wherein, described stator is wolfram steel.
Described screw rod point glue pump, wherein, described screw rod has lead.
Described screw rod point glue pump, wherein, glue inlet tube road is rustless steel, and cavity is sealed by O by screw lock.
Described screw rod point glue pump, wherein, glue inlet tube road enters glue end and arranges a screwed hole.
The screw rod point glue pump told, wherein, arranges O and seals between bottom and the cavity of the lead of screw rod.
The beneficial effects of the utility model are to provide one and put glue precision height, some adhesiveness scope extensively, and dispensing amount range of accommodation greatly, puts glue thickness adjustable extent greatly, screw arbor assembly nonabradable screw rod point glue pump.
Accompanying drawing explanation
Fig. 1 is the profile of this utility model screw rod point glue pump.
Detailed description of the invention
Below in conjunction with Fig. 1 and specific embodiment, this utility model is described in detail.
Embodiment 1
nullAs shown in Figure 1,A kind of screw rod point glue pump includes motor casing 2,In the bottom of motor casing, motor mount 5 is set,Motor 2 is arranged on motor mount 5,The output revolving shaft of motor is connected with screw rod 8 by shaft coupling 7,Screw rod 8 is driven to rotate,The spiro tooth part of screw rod sets up separately puts a stator 11,The side of stator 11 arranges glue feeding opening near thread top,Glue feeding opening is connected with glue inlet tube road 13,Glue inlet tube road 13 upper part arranges packing element 15,Connected by joint 14,The bottom of cavity 10 is arranged plastic hole and is connected by adaptor 12 with syringe needle,Between top and the cavity 10 of screw rod thread, sealing device is set,Motor casing 3 and cavity 10 keep fixing by fixed support 9,Motor 2 is fixed together with motor casing 3 by motor cabinet 5,Packing element 15 limits rocking of packing element 15 by packing element support 4.
In told screw rod point glue pump, shaft coupling 7 is set between motor 2 and screw rod 8, can protect motor and make screw rod more stable to the pressure of glue in respective range, and ensure that the concentric of screw rod 8 and stator 11.
In order to improve the life-span of building bar pump and can heat to screw rod point glue pump, screw rod 8 uses wolfram steel material, stator 11 to use rustless steel, adds heat energy and makes the viscosity of glue decline, and the some glue making screw rod point glue pump is wider.Screw rod 8 has a lead, makes screw rod 8 install more convenient, and can guarantee that screw rod 8 and the axiality of stator 11.
In order to ensure that not following stator in process glue inlet tube road 13 for dispensing glue shakes and then affect a glue precision, glue inlet tube road 13 stator 11 of getting along well is made of one.Fixed by screw between glue inlet tube road 13 and cavity 10, simultaneously in order to ensure not leak glue, an O is set in the junction in glue inlet tube road 13 and cavity 10.Glue inlet tube road 13 stainless steel can heat, and the viscosity of glue can be made to decline, and the some glue making screw rod point glue pump is wider.
In told screw rod point glue pump, the glue end that enters in glue inlet tube road 13 arranges a screwed hole, it is simple to observes glue situation in the duct and is easy to clean.
Screw rod point glue pump in order to prevent the wire drawing phenomenon of glue, generally uses the method that screw rod 8 inverts during for dispensing glue.In order to prevent glue glue screw rod 8 inverts when from not flowing out from upper end, an O is set between bottom and the cavity 10 of the lead of screw rod 8 and seals.
It should be appreciated that for those of ordinary skills, can modifications and variations the most in addition, and these modifications and variations used all should belong to the protection domain of appended claims of the present invention.
