All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] The present invention will be further described below with reference to the embodiments.

[0031] Embodiment:

[0032] Please refer to Figures 1-8 , the present invention provides a technical solution: a coating head system with a self-emptying inclined glue tank, including:

[0033] A stirring part 1, the stirring part 1 includes a fixing frame 11, the fixing frame 11 is rotatably connected with a material tank 12 through a shaft rod arranged inside it, two fixing frames 11 are provided and symmetrically distributed on both sides of the material tank 12, and a stirring member 13 is arranged inside the material tank 12;

[0034] A discharging part 2, the discharging part 2 includes a blanking pipe 21 and an emptying pipe 22, both the blanking pipe 21 and the emptying pipe 22 are fixedly communicated with the bottom end of the material tank 12, the included angle between the blanking pipe 21 and the emptying pipe 22 is 45 degrees, and an emptying assembly 23 is arranged inside the emptying pipe 22;

[0035] Among them, the stirring member 13 includes a driving seat arranged at the top of the material tank 12. A rotating shaft 131 is internally connected in the driving seat in a transmission manner. A hollow shaft 132 that rotates with the inside of the material tank 12 is sleeved on the outer surface of the rotating shaft 131. A stirring shaft 133 is slidably connected inside the hollow shaft 132. A stirring paddle 134 is fixedly connected to one side of the stirring shaft 133 away from the rotating shaft 131. A moving member 14 for driving the stirring paddle 134 to perform a horizontal displacement is arranged on one side of the stirring shaft 133 close to the center line of the material tank 12.

[0036] The moving member 14 includes a wedge block 141. The wedge block 141 is fixedly connected to one end of the stirring shaft 133 close to the center line of the material tank 12. An inclined groove 142 is formed on the circumferential outer surface of the rotating shaft 131. The inclined groove 142 is slidably connected to the outer surface of the wedge block 141 through a slide rail formed on its inner wall.

[0037] Two sets of stirring paddles 134 are arranged up and down. The two sets of stirring paddles 134 are staggeredly distributed. Each set of stirring paddles 134 has three. The stirring shaft 133 is designed in an inclined manner. And the lowest point of the upper stirring paddle 134 is lower than the highest point of the lower stirring paddle 134, which can cover all the inner wall sides of the material tank 12 and achieve the scraping and emptying of residual materials in all directions.

[0038] The emptying assembly 23 includes a through-hole sphere 231. The outer surface of the through-hole sphere 231 is in rolling connection with the inner wall surface of the emptying pipe 22. A valve rod 232 is fixedly connected to the outer surface of the through-hole sphere 231. The outer end of the valve rod 232 penetrates through the emptying pipe 22 and is fixedly connected to a connecting rod 233.

[0039] A waste box 234 is arranged below the material tank 12. A limiting block 236 that fits the outer surface of the connecting rod 233 is fixed on the waste box 234 through a bracket 235 fixed on its upper surface. The waste box 234 can be designed with a relatively large opening. In the vertical state, the lower part of the outlet end of the feeding pipe 21 is also collected and protected.

[0040] A base 15 is fixedly connected to one side of the waste box 234. A supporting block 152 that fits the outer surface of the material tank 12 is slidably connected to the base 15 through a hydraulic rod 151 arranged inside it. Two bases 15 are provided and are distributed on both sides of the material tank 12.

[0041] A ring sleeve 24 is fixedly connected to the outer surface of the waste box 234. A bent plate 241 is fixedly connected to the upper surface of the ring sleeve 24. A conveying pipe 242 is slidably connected to the circumferential inner wall of the ring sleeve 24. The conveying pipe 242 is connected to the upper surface of the bent plate 241 through a fixing ring 243 fixed on its outer surface.

[0042] The bottom of the blanking pipe 21 is fixedly connected with an inclined panel 211, and one end of the conveying pipe 242 close to the blanking pipe 21 is fixedly communicated with an L-shaped plate 244 that fits the outer surface of the inclined panel 211. When the material tank 12 changes from the vertical state to the inclined state, the outer ends of the contact surfaces between the L-shaped plate 244 and the inclined panel 211 are both designed with arc surfaces to facilitate the docking of the conveying pipe 242 and the blanking pipe 21, and the blanking pipe 21 is pressured by the bending plate 241 to make the contact surfaces between the L-shaped plate 244 and the inclined panel 211 fit tightly.

[0043] During coating, the process of continuously feeding the die head from the inside of the material tank 12:

[0044] In practical applications, a driving device is arranged inside the fixing frame 11 to drive the material tank 12 to rotate through a shaft rod. During the use of the coating head system, the driving device drives the material tank 12 to rotate 45 degrees from the vertical state. At this time, the whole material tank 12 rotates to the inclined state. In this state, the emptying pipe 22 is in the vertical state, the material tank 12 is communicated with the conveying pipe 242 through the emptying pipe 22, the central axes of the emptying pipe 22 and the conveying pipe 242 coincide, the conveying pipe 242 is made of hard metal material, and a pipe connected to the coating die head is fixedly connected to the lower surface of the conveying pipe 242. Therefore, in this state, the glue material is connected to the die head from the inside of the material tank 12 along the emptying pipe 22, the conveying pipe 242, and the pipe to provide a material source for glue coating.

[0045] The top of the material tank 12 is designed with relative sealing and integrally formed with a top plate. The driving seat is arranged above the top plate, and a feeding pipe is fixedly communicated with the side surface of the material tank 12. In the initial state, the glue material enters the inside of the material tank 12 from the feeding pipe, and a device for preventing foam generation is provided. To prevent the glue from precipitating and stratifying in the material tank 12, the stirring member 13 stirs the glue material inside. The base 15 drives the hydraulic rod 151 inside it to lift upward, and the upper surface of the supporting block 152 fits the lower surface of the bottom of the material tank 12 (the material tank 12 in the state of being inclined 45 degrees). There are two supporting blocks 152 to give the material tank 12 uniform supporting force to prevent instability caused by the operation of the stirring member 13 during the feeding process.

[0046] In the vertical direction, the length of the inclined groove 142 is greater than that of the wedge block 141. The slopes of the adjacent surfaces of the inclined groove 142 and the wedge block 141 are the same. The width of the lower part of the inclined groove 142 is longer, and the width of the upper part of the inclined groove 142 is shorter. In this state, the lower part of the inner wall of the wedge block 141 is in contact with the inclined groove 142. Under the action of the slide rail, the inclined surface of the wedge block 141 is always in contact with the inclined surface of the inner wall of the inclined groove 142. The wedge block 141 is fixedly connected to the stirring shaft 133 and the stirring paddle 134. Under the action of the moving part 14, the stirring shaft 133 and the stirring paddle 134 approach the central axis of the material tank 12. In the circumferential direction, the diameter enclosed by the plurality of stirring paddles 134 is at the minimum within its range. This diameter is smaller than the inner wall diameter of the material tank 12. The outer surface of the stirring paddle 134 does not contact the inner wall of the material tank 12, and there is a gap between them, which can avoid unnecessary wear on the inner wall of the material tank 12 while stirring the glue material. During the stirring process, if it is always in contact with the material tank 12, debris generated by friction will be mixed into the glue material, thus affecting the quality of the product. Especially for the production of products with extremely high purity requirements, such as electronics and optics products, it will cause serious impacts.

[0047] During the stirring process, the through-hole sphere 231 is in a closed state inside the drain pipe 22. The vertical section of the connecting rod 233 is parallel to the central axis of the material tank 12 (in an inclined state) (the connecting rod 233 includes a vertical section and a bent section, and the vertical section is directly connected to the outer end of the valve stem 232). The lower surface of the inclined panel 211 is in close contact with the upper surface of the L-shaped plate 244. The whole conveying pipe 242 is slightly pressed downward, and the bent plate 241 between the collar 24 and the fixed ring 243 is in a compressed state and undergoes elastic deformation. The side plate of the L-shaped plate 244 is in contact with the side surface of the inclined panel 211.

[0048] The rotating shaft 131 is connected to the keyway on the inner surface of the hollow shaft 132 through a key, and the torque of the rotating shaft 131 is transmitted to the hollow shaft 132, so as to apply different rotation speeds to the glue material by the stirring member 13. When the rotating shaft 131 rotates, the hollow shaft 132 rotates synchronously with the rotating shaft 131 through the key, and drives the stirring shaft 133 and the stirring paddle 134 to stir the glue material inside the material tank 12. The overall stirring speed is relatively slow. When the material tank 12 is in an inclined state, the area of the upper surface of the glue material liquid surface exposed is relatively large, and the depth of the liquid is relatively shallow. In this state, the stirring member 13 is also in an inclined state. Therefore, the plane where the multiple stirring shafts 133 are located together is no longer parallel to the upper surface of the glue material. While the stirring member 13 rotates radially inside, the component forces of the gravity of the glue material at different positions in the material tank 12 along the axial direction of the material tank 12 are also different. The component force of gravity of the glue material near the lower end is large, which will accelerate the downward flow; while the glue material near the upper end will be driven upward to supplement due to the flow of the fluid at the lower end, thus forming a natural convection cycle. When the stirring member 13 rotates, this convection is superimposed on the fluid motion pushed by the stirring paddle 134, making the fluid in the material tank 12 mix more evenly and effectively preventing precipitation. The inclined placement makes the stirring paddle 134 act more unevenly on the materials at different height positions in the material tank 12 during the rotation process. This uneven action promotes the glue material to generate more complex movement trajectories, further increasing the mixing degree between the glue materials. Compared with the vertical placement, the inclined placement can make the stirring paddle 134 produce a better stirring effect at the same rotation speed and more effectively prevent precipitation.

[0049] In the normal vertical state, the liquid surface is perpendicular to the material tank 12, and the liquid surface is also perpendicular to the stirring member 13. In this state, it is very difficult for the stirring member 13 to turn over in the vertical direction of the liquid level, and it can only turn over on the same horizontal plane, which is not conducive to fully avoiding the deposition and stratification of the glue material. It is easy to form a deposition dead angle in the central area at the bottom of the material tank 12. The centrifugal force and shear force generated by the stirring member 13 are difficult to completely cover this area, resulting in the material being easily accumulated and precipitated here. While the inclined placement can change the force and fluid flow state at the bottom of the material tank 12 and reduce the existence of such deposition dead angles. The glue material flows more smoothly at the bottom of the inclined material tank 12, and the acting force generated by the stirring paddle 134 can more evenly cover the entire bottom area, making it difficult for the material to accumulate and precipitate locally. Prevent the solid particles in the glue from depositing at the bottom and flowing into the die head along the pipeline, resulting in poor quality of the coated product.

[0050] The process of emptying the glue material inside the material tank 12:

[0051] After use, there is no excess glue material left in the material tank 12, and only remains on the inner wall surface. At this time, the hydraulic rod 151 drives the supporting block 152 on its upper surface to move downward to the contracted state, which does not affect the rotation of the material tank 12.

[0052] The feeding trough 12 is rotated by 45 degrees by a driving device. The conveying pipe 242 and the waste box 234 remain in a fixed relative position. The blanking pipe 21 and the inclined panel 211 are fixedly connected to the feeding trough 12 and move synchronously with the feeding trough 12. The relative position between the blanking pipe 21 and the conveying pipe 242 changes. The inclined panel 211 on the lower surface of the blanking pipe 21 disengages from the L-shaped plate 244 on the upper surface of the conveying pipe 242. Under the action of the bent plate 241, the fixing ring 243 drives the conveying pipe 242 to move slightly upward, and the bent plate 241 restores its elastic potential energy.

[0053] During the rotation of the feeding trough 12, when the feeding trough 12 is about to be in a vertical state, the outer end of the angled section of the connecting rod 233 is in contact with the outer surface of the limit block 236. When the feeding trough 12 is completely vertical, under the action of the limit block 236, the connecting rod 233 drives the valve stem 232 and the through-hole sphere 231 to rotate by 90 degrees, and the through-hole sphere 231 is then in communication with the inside of the emptying pipe 22 at this time. The lower surface of the emptying pipe 22 is directly connected to the waste box 234, enabling the collection of the remaining deposited waste.

[0054] After the feeding trough 12 is in a vertical state, the inside of the driving seat drives the rotating shaft 131 to press downward, so that the inclined surface of the wedge block 141 is in contact with the surface of the upper half of the inclined groove 142. The width of this part of the inclined groove 142 is relatively short, and the distance of the wedge block 141 inside the inclined groove 142 is relatively short. Since the inner wall surface of the inclined groove 142 is provided with a sliding rail for the wedge block 141 to slide, the inclined groove 142 is always in contact with the surface of the wedge block 141. In this state, the wedge block 141 drives the stirring shaft 133 and the stirring paddle 134 to move outward synchronously until the stirring paddle 134 is in contact with the inner wall of the feeding trough 12, and there is no gap between the feeding trough 12 and the stirring paddle 134. In the circumferential direction, the diameter formed by the multiple stirring paddles 134 is the same as the diameter of the feeding trough 12, which can scrape the glue material remaining on the inner wall of the feeding trough 12. It can be in contact with the inner wall of the feeding trough 12 to scrape the remaining material, avoiding cross-contamination next time, improving the cleaning efficiency, and reducing the production cost.

[0055] The stirring paddles 134 are divided into upper and lower groups, and the moving member 14 only drives the stirring paddles 134 to contract and expand in the radial direction. When emptying the remaining material in the feeding trough 12, the outer surface of the upper stirring paddle 134 is in contact with the inner wall of the cylindrical feeding trough 12, and the outer surface of the lower stirring paddle 134 is in contact with the arc-shaped bottom surface of the feeding trough 12; when the feeding trough 12 is in normal use for feeding the die head, since the bottom of the lower stirring paddle 134 also adopts a curved arc surface design that is in contact with the arc-shaped bottom surface of the feeding trough 12, the lower stirring paddle 134 contracts in the radial direction, enabling the outer surface of the stirring paddle 134 not to be in contact with the inner wall of the feeding trough 12 in both the circumferential direction and the vertical direction.

[0056] In summary, the feeding trough 12 has the following advantages during the emptying process:

[0057] Advantage 1: In the initial state, in order to ensure the coating quality and prevent phenomena such as precipitation and stratification of the glue material, the stirring member 13 in the material tank 12 needs to stir the glue material inside. At this time, the stirring member 13 is in a contracted state, and the diameter enclosed by the multiple stirring paddles 134 in the circumferential direction is smaller than the diameter of the material tank 12. This can avoid unnecessary wear caused by continuous friction against the inner wall of the material tank 12 during frequent use, and prevent debris generated by friction from mixing into the glue material and being discharged along with the glue material, affecting the coating effect. Thus, the purity of the glue material is ensured, and the coating quality is guaranteed. When the use is completed and the material tank 12 is emptied, the rotating shaft 131 moves downward, and the expansion of the stirring paddle 134 is realized through the moving member 14, so that the outer surface of the stirring paddle 134 fits the inner wall of the material tank 12, and the waste deposited on the inner wall of the material tank 12 can be scraped off.

[0058] Advantage 2: When the material tank 12 is emptied, it rotates to a vertical state. The limiting block 236 drives the connecting rod 233, the valve rod 232, and the through-hole sphere 231 to rotate, so that the through-hole sphere 231 communicates with the emptying pipe 22, realizing the collection of the remaining deposited waste. At the same time, under the action of the moving member 14, the stirring paddle 134 moves outward to fit the inner wall of the material tank 12, which can scrape off the glue material remaining on the inner wall of the material tank 12, avoiding cross-contamination during the next use and improving the cleaning efficiency. The material tank 12 is driven by the driving device to rotate to an inclined state, so that the emptying pipe 22 communicates with the conveying pipe 242, and the glue material can continuously flow from the material tank 12 to the die head along the pipeline, providing a stable material source for coating.

[0059] Advantage 3: The inclined placement of the material tank 12 makes the action of the stirring paddle 134 on the materials at different height positions uneven, promoting the glue material to generate a more complex movement trajectory, increasing the mixing degree between the glue materials. Compared with the vertical placement, it can produce a better stirring effect at the same rotation speed. At the same time, the material tank 12 is placed obliquely, and the exposed surface area of the glue material inside increases. During the flow of the glue material, the inclined material tank 12 can help the bubbles to be discharged more easily. The inclined surface gives the bubbles a greater chance to rise to the surface of the glue material and burst, avoiding the bubbles from entering the pipeline and the die head along with the glue material, thus preventing bubble defects during the coating process and improving the surface quality of the product. The inclined placement of the material tank 12 enables the glue material to form a natural convection cycle, which is superimposed on the fluid movement pushed by the stirring paddle 134, making the fluid mixture more uniform and effectively preventing precipitation and stratification.

[0060] Advantage 4: When the material tank 12 is in normal feeding use, the inside of the material tank 12 is in a relatively sealed state, the feeding port is closed, and the through-hole sphere 231 in the emptying pipe 22 separates it from the outside. The inclined panel 211 on the lower surface of the discharging pipe 21 and the L-shaped plate 244 on the upper surface of the conveying pipe 242 are tightly fitted through the bent plate 241 to achieve relative sealing. After the coating is completed, by rotating the material tank 12, the emptying pipe 22 can be in an open state, and the discharging pipe 21 and the conveying pipe 242 are no longer connected and are also in an open state. The outside air can enter the material tank 12 to make the air pressure in the material tank 12 balanced with the outside, so that the glue material can be discharged more smoothly from the bottom under the action of gravity.

[0061] Advantage 5: There are two sets of stirring paddles 134, upper and lower, and the lowest point of the stirring paddle 134 closer to the upper part is lower than the highest point of the stirring paddle 134 closer to the lower part, which can cover all the inner wall sides of the material tank 12, and can comprehensively scrape and empty the residual materials without leaving any cleaning dead corners, which helps to keep the inside of the material tank 12 clean and reduce the corrosion and damage of the inner wall of the material tank 12 caused by material residue.
