Description
Technical field
The utility model relates to foaming machine, is specifically related to high pressure foaming machine hybrid gun head.
Background technology
High pressure foaming machine hybrid gun head is the significant components of polyurethane foaming machine, effect: A is expected that (carbimide) and B are sprayed by stuff-spraying pipe after expecting (polyethers) Homogeneous phase mixing.Existing hybrid gun head has following shortcoming (as shown in Figure 1):
Due to pressure transient when work, cause mixing material that is uneven, ejection and produce splash phenomena, PU goods easily have bubble to produce, and stuff-spraying pipe easily blocks.
There is no instantaneous cleaning device; due to the characteristic of polyurethane products raw material, can there is chemical reaction (condensation), upon mixing very soon so when equipment downtime in A material and B material; clean the raw material of the remnants in high pressure mixing cavity not in time, be easy to cavity is blocked.
The putty bolt of stuff-spraying pipe head is not smooth plane due to end face, in A material and B material impact putty bolt end face in case of high pressures in actual production process, easily produces buildup.After long-time, the head of stuff-spraying pipe also easily blocks.
Utility model content
Technical problem to be solved in the utility model is that the mixing of existing high pressure foaming machine hybrid gun head is uneven, stuff-spraying pipe easily blocks, and cleaning is inconvenient.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is to provide a kind of high pressure foaming machine hybrid gun head, comprise the rifle head body of T-shaped, high pressure mixing cavity is provided with in described rifle head body, the two ends, left and right of described rifle head body are respectively equipped with B and expect that import and A expect import, the right part of described rifle head body is inserted with adjustment thimble, the left part of described adjustment thimble has a spring, the bottom of described rifle head body is stuff-spraying pipe, the bottom of described stuff-spraying pipe is provided with putty bolt, the top of described high pressure mixing cavity is provided with a cleaning cylinder, the piston rod of described cleaning cylinder is fixed with a sub warhead, the middle part of described rifle head body has a cleaning agent entrance, described sub warhead moves down gear at cleaning agent entrance.
Further technical scheme, the top end face of described putty bolt is smooth inclined-plane.
Further technical scheme, the bevel inclination angle of described putty bolt is 45 degree.
The utility model provides a kind of high pressure foaming machine hybrid gun head, adds cleaning device, improves production efficiency and product quality, decrease the fault rate of hybrid gun head in hybrid gun head.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing high pressure foaming machine hybrid gun head;
The structural representation of the high pressure foaming machine hybrid gun head that Fig. 2 provides for the utility model.
In figure: 1. clean cylinder, 2. sub warhead, 3. high pressure mixing cavity, 4. spring, 5. regulate thimble, 6. stuff-spraying pipe, 7. putty bolt, 8.A expects entrance, and 9.B expects entrance, 10. cleaning agent entrance.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
As shown in Figure 2, the high pressure foaming machine hybrid gun head that the utility model provides comprises the rifle head body of T-shaped, high pressure mixing cavity is provided with in rifle head body, the two ends, left and right of rifle head body are respectively equipped with B and expect that import and A expect import, the right part of rifle head body is inserted with adjustment thimble, regulate the left part of thimble to have a spring, the bottom of rifle head body is stuff-spraying pipe, and the bottom of stuff-spraying pipe is provided with putty bolt.The top of high pressure mixing cavity is also provided with a cleaning cylinder, and the piston rod of cleaning cylinder is fixed with a sub warhead, and the middle part of rifle head body has a cleaning agent entrance, and sub warhead moves down gear at cleaning agent entrance.
The top end face of putty bolt is smooth inclined-plane, and in the utility model, the angle of inclination on inclined-plane is 45 degree.
The high pressure foaming machine hybrid gun head that the utility model provides has the following advantages:
1, improve the stability of operating pressure, we improve machining accuracy to all parts, have changed the material regulating spring on thimble, have improve fatigue strength and the spring plane degree of spring.Thus improve the stability of spring, during guarantee work, pressure is stable.
2, add cleaning cylinder, when A, B material is reinforced, clean cylinder is opened, and the sub warhead that cylinder piston rod connects blocks cleaning agent entrance; When A, B material stops reinforced time, clean cylinder resets, and cleaning agent is introduced from cleaning agent entrance, flows out from stuff-spraying pipe, and the inner and stuff-spraying pipe of this process cleaning mixing chamber, avoids the blocking of mixing chamber and stuff-spraying pipe.
3, improve the form of putty bolt, the end face of putty bolt changes the form at smooth band 45 degree of oblique angles into, is just not easy to produce buildup like this, avoids the generation of stopping state at the head of stuff-spraying pipe.
The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structure change made under enlightenment of the present utility model, and every have identical or close technical scheme with the utility model, all falls within protection domain of the present utility model.
