Description

Technical Field

[0001] The utility model relates to the technical field of glue pouring equipment, in particular to a two-component glue pouring device. Background Art

[0002] The traditional two-component AB glue filling process is usually: manually weigh and quantitatively take A glue and B glue according to the ratio of AB glue, stir and mix the AB glue in a cup, and then use a syringe to suck the mixed glue and pour it into the glue filling tank of the product. According to this method, the operation steps are many and the process is complicated. The tolerance of the glue filling amount is difficult to control, the production efficiency is low, and it becomes a bottleneck in the production process. It is also easy to cause problems such as work surface pollution. Due to the mixing characteristics of AB glue, after mixing and stirring evenly, the mixed glue to be used will gradually thicken or even solidify. If the amount of glue mixed at one time is too much, the subsequent mixed glue will be difficult to absorb with a syringe, resulting in waste of glue. Therefore, a shift of production requires repeated weighing, mixing, stirring and mixing of glue. This can easily lead to human error, imbalance of weighing ratio or uneven manual stirring, resulting in the glue not drying and unable to bond the product, and overflow of glue to contaminate the product, affecting product quality.

[0003] Chinese patent document CN219923522U discloses a cylinder harness glue pouring mixing mechanism, which changes the proportioning, mixing and glue pouring of two-component colloids from manual operation to machine operation, thereby improving the efficiency and qualified rate of glue pouring. However, the mixed colloid is completed in the mixing cylinder, and the mixing cylinder is provided with a spiral mixing plate driven by a motor, the discharge end of the mixing cylinder is connected to a glue injection needle, and the stop valve for suspending the discharge of glue is arranged between the glue injection needle and the mixing cylinder. It can be seen that the mixing structure of the entire mixed colloid is not replaceable; therefore, the mixed colloid will be stored in the mixing cylinder for a long time. This type of equipment is suitable for some glues that require specific conditions (such as UV light irradiation or high temperature heating) to solidify. For mixed glues that will naturally solidify after a period of time in a natural environment (normal temperature and pressure), this type of equipment is not suitable. At present, the mixing of this type of two-component colloid is still mainly done by manual operation. Summary of the invention

[0006] In one embodiment, the cross-sectional area ratio of the A and B rubber tubes is consistent with the ratio of the A and B colloids, and the movement speed of the A colloid in the A rubber tube is the same as the movement speed of the B colloid in the B rubber tube.

The A pusher is sealed with the inner wall of the A glue tube. The A pusher moves into the A glue tube and moves in the A glue tube to push the A glue to flow to the mixing glue tube. The B pusher is sealed with the inner wall of the B glue tube. The B pusher moves into the B glue tube and moves in the B glue tube to push the B glue to flow to the mixing glue tube.

[0008] In one embodiment, it also includes a controller, which is used to control the feed amount of the glue pushing assembly in the axial direction of the glue supply hose group to control the glue output amount of the A and B colloids; the frame is provided with a first limit travel switch and a second limit travel switch electrically connected to the controller, the first limit travel switch is used to limit the glue pushing assembly to move to the lower limit position when it is located in the glue supply hose group, and the second limit travel switch is used to limit the glue pushing assembly to move to the upper limit position when it leaves the glue supply hose group.

[0010] In one embodiment, the A rubber tube is provided with an A glue outlet, and the B rubber tube is provided with a B glue outlet. The A colloid and the B colloid in the rubber supply hose group flow out from the A glue outlet and the B glue outlet respectively. A sealing joint is also provided for replacing the mixing rubber hose connected to the rubber supply hose group. The sealing joint is used to seal the A glue outlet and the B glue outlet to prevent the colloid in the rubber supply hose group from flowing out from the corresponding glue outlet when the mixing rubber hose is separated.

DETAILED DESCRIPTION

[0019] To further illustrate the various embodiments, the present invention provides drawings. These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, a person of ordinary skill in the art should be able to understand other possible implementations and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0020] See also Figures 1 to 4 As shown, the utility model discloses a two-component glue pouring device, which is used to mix colloid A and colloid B evenly to form a two-component mixed glue, and then discharge it to a preset glue pouring area of ​​the product, thereby completing mechanized glue mixing and glue pouring, and solving the problems of low efficiency and low qualified rate in manual glue pouring.

[0021] The glue filling device includes a frame 1, on which a glue pushing and feeding mechanism 2, a glue supply hose group 3 and a glue mixing hose 4 are provided. The glue supply hose group 3 includes an A glue hose 31 and a B glue hose 32 which are independent of each other. The A glue hose 31 is used to accommodate the A glue, and the B glue hose 32 is used to accommodate the B glue. The glue mixing hose 4 is detachably connected to the glue supply hose group 3, and the glue mixing hose 4 is connected with the A glue hose 31 and the B glue hose 32 through pipelines. The glue pushing and feeding mechanism 2 is used to drive the A and B glues in the glue supply hose group 3 to flow to the glue mixing hose 4 for mixing. The glue mixing hose 4 is provided with a spiral glue mixing channel (not shown in the figure) so that the A and B glues with a certain proportion from the glue supply hose group 3 flow through the spiral glue mixing channel, are mixed and flow out from the glue filling port 40 at the end of the glue mixing hose 4.

[0022] The glue push feeding mechanism 2 applies pressure to the glue supply hose group so that the A and B colloids in the A and B hoses 31 and 32 flow out to the mixing hose 4 according to the set ratio, and then flow out from the glue filling port 40 after being fully mixed in the spiral mixing channel, thereby realizing the mechanized operation of mixing and filling, and improving the efficiency of filling. In addition, the A and B colloids are supplied to the mixing hose 4 according to the set ratio, which overcomes the problem that the mixed glue cannot be dried and solidified due to the inaccurate ratio of the A and B colloids in manual mixing, thereby improving the qualified rate of glue filling. The mixing hose 4 of the utility model is a universal part made of plastic, which has a low cost and a good mixing effect. When the colloid inside it is solidified or the type of colloid is changed, the mixing hose 4 can be directly replaced, which is low in cost and easy to operate.

[0023] The cross-sectional area ratio of the A and B hoses is consistent with the ratio of the A and B colloids. The moving speed of the A colloid in the A hose 31 is the same as the moving speed of the B colloid in the B hose 32. The weight control ratio in the manual glue mixing operation is converted into a volume control ratio. The control is simpler, and the weighing-related structure can be saved, simplifying the overall structure of the glue filling device. In this example, the ratio of the A colloid to the B colloid is 1:4. In other embodiments, depending on the type of colloid, it can be other ratios, such as 1:1.

[0024] The glue pushing and feeding mechanism 2 includes a glue pushing component 21 and a driving component 22 for driving the glue pushing component 21 to feed axially along the glue supply hose group 3. Both the A glue hose 31 and the B glue hose 32 are hard hoses. The glue pushing component 21 can selectively move inside and outside the glue supply hose group 3. When the glue pushing component 21 moves inside the glue supply hose group 3, it can push the glue inside it to move toward the mixing hose direction. When the glue pushing component moves to the outside of the glue supply hose group 3, the glue supply hose group 3 can be removed to replace another glue supply hose group 3 or add glue to the glue supply hose group 3.

[0025] The rubber pushing component 21 includes an A pushing piece 211 and a B pushing piece 212 that move synchronously. The A pushing piece 211 is in sealing cooperation with the inner wall of the A rubber tube 31. The A pushing piece 211 moves into the A rubber tube 31 and moves in the A rubber tube 31 to push the A colloid to flow to the mixing rubber tube 4. The B pushing piece 212 is in sealing cooperation with the inner wall of the B rubber tube 32. The B pushing piece 212 moves into the B rubber tube 32 and moves in the B rubber tube 32 to push the B colloid to flow to the mixing rubber tube 4.

[0026] The driving assembly 22 includes a motor-screw driving mechanism, the screw 221 extends along the axial direction of the supply hose group 3, and the screw 221 rotates under the drive of the motor 222. The push assembly 21 includes a push block 213 fixedly connected to the A push piece 211 and the B push piece 212. The push block 213 is connected to the screw 221 and moves axially along the screw 221 as the screw 221 rotates, thereby driving the A push piece 211 and the B push piece 212 to move synchronously along the axial direction of the supply hose group 3, so that the movement speed of the A colloid in the A hose 31 is the same as the movement speed of the B colloid in the B hose 32.

[0027] The glue filling device also includes a controller 5, which is used to control the feeding amount of the glue pushing component 21 in the axial direction of the glue supply hose group 3 to control the glue output amount of the A and B colloids; the frame 1 is provided with a first limit travel switch 61 and a second limit travel switch 62 electrically connected to the controller 5, the first limit travel switch 61 is used to limit the glue pushing component 21 to move to the lower limit position when it is located in the glue supply hose group 3, and the second limit travel switch 62 is used to limit the glue pushing component 21 to move to the upper limit position when it leaves the glue supply hose group 3. Specifically, the first limit travel switch 61 and the second limit travel switch 62 are photoelectric sensors facing the direction of the lead screw 221, respectively. When the push block 213 moves to the photoelectric detection range of the first limit travel switch 61 or the second limit travel switch 62, the first limit travel switch 61 or the second limit travel switch 62 sends a corresponding in-position signal to the controller, and the controller 5 controls the motor to stop, thereby stopping the glue pushing component 21 from rising or falling. When the first limit travel switch 61 detects the push block 213, it indicates that the glue push assembly 21 has reached the lower limit, and the glue in the glue supply hose group 3 is insufficient and needs to be replenished. At this time, the controller 5 controls the motor to rotate in the opposite direction to drive the glue push assembly 21 to rise until the second limit travel switch 62 detects the push block 213, and the motor stops rotating. At this time, the A push piece 211 and the B push piece 212 have moved outside the A glue hose 31 and the B glue hose 32, and the glue supply hose group 3 can be removed to add glue or replaced with a new one, or new A glue and B glue can be directly added to the glue supply hose group 3.

[0028] See also Figure 3 As shown, the A rubber tube 31 is provided with an A glue outlet 310, and the B rubber tube 32 is provided with a B glue outlet 320. The A glue and the B glue in the rubber supply tube group flow out from the A glue outlet 310 and the B glue outlet 320 respectively, and flow to the mixing rubber tube 4 for subsequent mixing and pouring. A sealing joint 33 is also provided for replacing the mixing rubber tube 4 and connecting it to the rubber supply tube group 3. The sealing joint 33 is used to seal the A glue outlet 310 and the B glue outlet 320 to prevent the glue in the rubber supply tube group 3 from flowing out from the corresponding glue outlets when the rubber supply tube group 3 is separated from the mixing rubber tube 4.

[0029] See also Figures 1 to 4 As shown, the supply hose group 3 of this example is detachably connected to the frame 1, so that the supply hose group 3 can be removed to add glue or replace with a new supply hose group. Specifically, the lower end of the supply hose group 3 is placed on the support plate 11, and the outer side of the upper end of the supply hose group 3 is restricted between the pressure piece 12 and the frame 1 by the pressure piece 12. The support plate 11 is fixedly connected to the frame 1, and the pressure piece 12 is threadedly connected to the frame 1. By removing the pressure piece 12, the restriction on the supply hose group 3 is released, so that the supply hose group 3 can be detached relative to the frame 1.

[0030] In other embodiments, the glue supply hose group 3 may also be fixedly connected to the frame, so that the glue is replenished into the glue supply hose group 3 through an additionally provided glue supply pipeline.

[0031] Figure 4 The figure shows the use state of the glue filling device. The product 100 to be filled with glue is placed under the glue filling port 40 of the glue mixing tube 4. As the motor 222 rotates, the A pusher 211 and the B pusher 212 move in the A glue tube 31 and the B glue tube 32 respectively to push the A glue and the B glue into the glue mixing tube 4. The A glue and the B glue are fully spiraled in the spiral glue mixing channel and mixed to form a mixed glue, which is then discharged from the glue filling port 40 to the glue filling area of ​​the product 100 to be filled with glue. Among them, the alignment of the glue filling port 40 and the glue filling area of ​​the product 100 to be filled with glue can be controlled manually or by another mechanism, which is not within the scope of protection of the utility model and will not be described in detail here.

[0032] Although the present invention is specifically demonstrated and described in conjunction with the preferred embodiments, those skilled in the art should understand that the remaining undescribed portions are prior art, and that various changes made to the present invention in form and detail without departing from the spirit and scope of the present invention as defined in the appended claims shall fall within the scope of protection of the present invention.
