Description

Technical Field

[0001] The invention relates to the technical field of glue injection equipment, in particular to a glue injection head. Background Art

[0002] The glue injection machine is an automated machine that controls the fluid and drips, coats, and fills the liquid on the surface or inside of the product to achieve the functions of sealing, fixing, and waterproofing. Generally, two-component glue is used. It is mainly used for bonding, pouring, coating, sealing, and filling of glue, oil, and other liquids in product processes. The automated glue injection device can realize the glue filling of irregular shapes such as points, lines, arcs, and circles. The current glue injection machines all have a glue injection head. The inventor found that in the prior art, when the glue liquid flows out of the glue injection nozzle, the glue liquid is mixed unevenly, resulting in uneven product quality, which is not conducive to mass production of products without inspection and causes waste of resources.

[0003] As the name suggests, the high-pressure press uses a high-pressure collision to mix materials. If no subsequent processing is done, the materials will have strong kinetic energy and will be ejected from the injection port. Although there have been some solutions for traditional high-pressure presses to reduce the material outlet pressure, they are only limited to the gluing process on the surface of some large-area plates and cannot meet the requirements of some slender and narrow strip-type injection processes.

[0004] The present invention improves some structures, and at the same time, it consumes the kinetic energy of the material, thereby forming a self-flowing effect at the outlet, and can meet the requirements of the mold opening casting process with slender and narrow requirements. Summary of the invention

[0009] The discharge port at the bottom of the upper cavity is connected to the glue injection nozzle, the outer side of the glue injection nozzle is provided with through holes, which are distributed in a cross shape, and the bottom of the inner cavity of the glue injection nozzle where the through holes are located is provided with a plug for causing the fluid to be blocked and flow back to achieve further mixing;

[0010] The lower cavity is formed by the inner cavity between the glue injection nozzle and the connecting part. The glue liquid is sprayed along the through hole on the glue injection nozzle to reach the side wall of the connecting part in the lower cavity, thereby achieving further mixing of the materials.

[0013] As a further solution of the present invention: the diameter of the opening is smaller than the diameter of the upper end surface of the cache box.

[0014] As a further solution of the present invention: the number of the discharge pipes is at least two.

[0015] As a further solution of the present invention: the guide column includes a column handle and a connecting thread arranged on the surface thereof, a blocking plate is provided at the end of the column handle, and the blocking surface of the blocking plate is provided with a collection trough, the bottom of the collection trough is an inclined surface, and the surface of the collection trough on the lower side of the inclined surface is provided with a discharge nozzle.

Through multiple guide columns, the fluid can rotate while flowing, which helps to improve the mixing effect.

[0016] As a further solution of the present invention: the inclined surface has an angle of forty-five degrees.

[0017] As a further solution of the present invention: a plurality of dividing rods for dividing the fluid are evenly distributed on the surface of the inclined surface.

[0019] Compared with the prior art, the beneficial effects of the present invention are: the present application fills the gap in the field of micro-high pressure mixing in the glue injection head, expands new product equipment, and reduces the manufacturing cost of the glue injection head because the stirring device in the prior art is not used, and the glue liquid is mixed five times, so that the glue liquid is fully mixed, saving materials, improving the utilization rate of materials, realizing mold opening and pouring, increasing the scope of use of the glue injection head, and creating profits.

[0020] Another point is that the traditional high-pressure machine has a large pouring volume, which is called "discharge volume" in jargon, about 400 to 500 grams per second. Otherwise, the basic requirement of collision mixing cannot be met. The mixing chamber in the present invention is a slender deep hole, so that even a small discharge volume can accumulate high kinetic energy, thereby meeting the requirement of collision mixing. The application range of the machine is wider, filling the gaps in many fields. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Example 1

[0030] See also Figure 1-2 In an embodiment of the present invention, a glue injection head includes a body 10, wherein the body 10 includes an upper cavity 22 and a lower cavity 24, wherein the upper cavity 22 includes a glue injection channel, wherein at least two glue inlet holes 11 are arranged on the outer side of the upper end of the glue injection channel, wherein each glue inlet hole 11 is provided with a glue inlet channel 25, wherein each glue inlet hole 11 is arranged opposite to each other, wherein the outer port of the glue inlet hole 11 is connected to the discharge end of a micro-high pressure regulating device 27 through a rubber hose 26, and the feed end of the micro-high pressure regulating device 27 is connected to a feeding component;

[0031] The glue injection channel is further provided with a glue injection portion 13, and a mixing chamber 23 for increasing the degree of fluid turbulence is provided inside the glue injection portion 13. A mixing mechanism is provided inside the mixing chamber 23, and the mixing mechanism includes threaded holes opened on the outside of the body 10, and the threaded holes are staggered at 90 degrees along the circumferential direction, and adjacent threaded holes are kept at a distance, and each threaded hole is matched with a guide column 14 extending into the mixing chamber 23, and the guide surface of the guide column 14 is set at an acute angle to the horizontal plane, and the force of the multiple guide columns 14 on the fluid constructs a rotational force that causes the material to rotate, thereby promoting the mixing of the material;

[0032] The discharge port at the bottom of the upper cavity 22 is connected to the glue injection nozzle 21. Through holes are provided on the outside of the glue injection nozzle 21 in a cross-shaped distribution. The bottom of the inner cavity of the glue injection nozzle 21 where the through holes are located is provided with a plug 15 for causing the fluid to be blocked and flow back to achieve further mixing.

[0033] The lower cavity 24 is formed by the inner cavity between the glue injection nozzle 21 and the connecting portion 12. The glue liquid is sprayed along the through hole on the glue injection nozzle 21 to reach the side wall of the connecting portion in the lower cavity, thereby further mixing the materials.

[0034] The plug 15 is threadedly connected to the glue injection nozzle 21 .

[0035] The working principle of the present invention is: the guide column is installed at the threaded hole on the glue injection part, and the number is at least four, one end of the guide column is in contact with the inner wall of the glue injection part, and the other end does not exceed the outer wall of the glue injection part; then the plug is installed at the bottom of the glue injection nozzle through a threaded connection without blocking the through hole on the glue injection nozzle, and then the glue injection part is installed inside the connecting part, and the glue inlet hole on the connecting part is correspondingly connected with the glue inlet channel on the glue injection part; then the glue inlet hole is connected to the micro-high pressure regulating device through a rubber hose. The mixing process of the glue liquid is to control and set its flow rate and pressure through a micro-high-pressure regulating device, and enter the upper cavity through the glue inlet hole for high-pressure collision to achieve the first mixing; the glue liquid mixed for the first time flows through the guide column and collides violently with the guide column to achieve the second mixing, and at the same time, the movement of the glue liquid changes from horizontal flow to turbulent flow, and because the cavity is a slender small hole, the glue liquid changes to a turbulent state and continuously collides with the side wall of the cavity to achieve the third deep mixing of the glue liquid; the glue liquid mixed for the third time flows through the blockage, and due to the formation of a blind hole at the blockage, the glue liquid is blocked from backflow and sprayed out from the through hole on the glue injection nozzle to achieve the fourth mixing of the glue liquid; then the glue liquid sprayed from the through hole on the glue injection nozzle reaches the side wall of the connecting part in the lower cavity and collides to achieve the fifth mixing. After the fifth mixing, the aperture becomes open, and at the same time, the kinetic energy of the glue is exhausted after multiple collisions, and it flows out of the glue injection hole in a self-flowing state. At the same time, the kinetic energy of the glue liquid changes to horizontal flow and flows out of the lower cavity is sufficient, which can be used for mold opening and pouring.

[0036] Example 2

[0037] See also Figure 3, which is different from Example 1 in that: the plug 15 includes a connecting column 151, the connecting column 151 is provided with a threaded area 152 for connection, the end of the connecting column 151 is rotatably connected to a cache box 153, the cache box 153 is provided with a cache cavity 154, the upper end surface of the cache box 153 is provided with an opening 157 for facilitating the entry of materials, the diameter of the opening 157 is smaller than the diameter of the upper end surface of the cache box 153, the end of the cache box 153 where the opening 157 is located is provided with a conical cover 155, the outer side of the cache box 153 is provided with a plurality of discharge pipes 156 for facilitating the discharge of fluids, the axis of the discharge pipe 156 is aligned with the cache The tangent angle of the box 153 is an acute angle, and the number of the discharge pipes 156 is at least two. The discharge pipes 156 do not contact the through hole of the injection nozzle 21. In actual use, the fluid enters the cache box 153 under the guidance of the conical cover 155. Since the conical cover 155 itself will compress the fluid, the compressed fluid will expand when entering the cache box 153, and finally hit the bottom of the cache box 153. Then the fluid will be discharged along the discharge pipe 156, and the discharged material will generate a reaction force on the discharge pipe 156. Multiple reaction forces construct a torque that causes the cache box 153 to rotate, thereby further promoting the mixing of the fluid.

In actual use, the fluid will hit the blocking plate 145, and the fluid will enter the collection groove 143. Under the guidance of the inclined surface 146, the fluid will be obliquely discharged along the discharge nozzle 144. Through multiple guide columns 14, the fluid can rotate when flowing, which is helpful to improve the mixing effect. A number of dividing rods for dividing the fluid are evenly distributed on the surface of the inclined surface 146. The dividing rod is a rectangular plate, and two adjacent rectangular plates are arranged at a V-shaped angle.
