Description

Technical Field

[0001] This utility model belongs to the field of glue injection gun technology, and in particular relates to a glue injection device for laminated glass. Background Technology

[0002] The glue injection gun is a glue injection device for laminated glass. Because it is specifically used to inject adhesive into the sealed cavity between two pieces of glass, it is a key execution device in the wet lamination process. In the existing technology, laminated glass often adopts a structure of three-sided sealing and one-sided glue injection. The glue injection gun connects its glue outlet with the glue injection port to accurately deliver liquid glue such as silicone or polyurethane into the cavity to achieve glue layer filling and bonding.

[0003] When using existing electric or manual glue guns for wet glue application, it is usually only possible to achieve a constant glue injection speed. It is difficult to dynamically adjust the injection rate to match the glue flow during the filling stage within the cavity. Ideally, a three-stage flow filling strategy should be adopted: slow injection at the bottom, fast injection in the middle, and slow injection at the top. The initial slow speed helps to form a stable laminar flow front and avoids air entrainment; the rapid injection in the middle increases efficiency and prevents premature thickening of the glue; and the slow speed at the end prevents over-rushing, clogging of the vent, and retention of residual air bubbles. However, traditional glue guns lack intelligent speed adjustment capabilities and cannot perform this process. Operators need to manually control the trigger force based on experience, which not only makes it difficult to accurately achieve variable speed injection but also easily introduces air bubbles due to improper operation, significantly reducing the glue injection quality and ease of construction. Utility Model Content

[0004] The purpose of this utility model is to provide a glue injection device for laminated glass. Through the cooperation between components such as the screw rod, stepper motor and transmission mechanism, variable speed glue injection and easy maintenance are achieved, thus improving the convenience of the glue injection device.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a glue injection device for laminated glass, comprising a first assembly shell, a second assembly shell, a glue filling cylinder, and a glue injection nozzle. The second assembly shell is bolted to the first assembly shell, and the glue filling cylinder is threaded to the top of the first assembly shell. The interior of the first assembly shell and the interior of the glue filling cylinder are in communication. The glue injection nozzle is threaded to one end of the first assembly shell, and a spiral rod is provided inside the first assembly shell. A stepper motor is fixedly connected to the other end of the first assembly shell, and a transmission mechanism for driving the spiral rod to rotate is installed inside the first assembly shell.

[0006] Furthermore, the transmission mechanism includes a rotating frame, a first positioning block, a second positioning block, and a positioning shell. The rotating frame is fixedly connected to the inner wall of the first assembly shell, and the first positioning block is rotatably connected to the rotating frame. The output shaft of the stepper motor is fixedly connected to the second positioning block located inside the first assembly shell. Positioning shells are fixedly connected to both ends of the spiral rod, one of the positioning shells being bolted to the first positioning block, and the other positioning shell being bolted to the second positioning block.

[0007] Furthermore, the positioning shell has a concave design.

[0008] Furthermore, semi-circular ring blocks are symmetrically fixedly connected to both the first assembly shell surface and the second assembly shell surface, and a first heating sleeve is provided between the two semi-circular ring blocks and sleeved on the first assembly shell surface and the second assembly shell surface.

[0009] Furthermore, the surface of the glue-filling cylinder is symmetrically fixedly connected with ring blocks, and a second heating sleeve is provided between the two ring blocks and sleeved on the surface of the glue-filling cylinder.

[0010] Furthermore, the top of the glue-filling cylinder has an injection port, and the injection port has a sealing cap inside.

[0011] Furthermore, a positioning frame is symmetrically fixedly connected to the top of the glue-filling cylinder.

[0012] This utility model has the following beneficial effects: This invention, through the installation of a screw rod, a stepper motor, and a transmission mechanism, first loads the colloid material into the dispensing cylinder, which is threadedly connected to the first assembly shell. The stepper motor is then started, and the transmission mechanism drives the screw rod to rotate, delivering the colloid to the dispensing nozzle. The stepper motor adjusts its speed to control the screw rod's rotation speed, thus controlling the colloid delivery speed and achieving a dispensing sequence of slow start, fast middle, and slow stop at the end. After a period of use, the second assembly shell is removed, and the colloid adhering to the surface of the screw rod inside the first assembly shell is cleaned. This gives the dispensing device the functions of automatic variable-speed colloid delivery and convenient maintenance.

[0013] This utility model involves installing a rotating frame, a first positioning block, a second positioning block, and a positioning shell. By loosening the bolts on the surface of the positioning shell, the positioning shell is separated from the first and second positioning blocks. The spiral rod is then cleaned and maintained. After cleaning, the spiral rod is placed inside the first assembly shell. Bolts securely connect the first and second positioning blocks to the positioning shell. When the stepper motor output shaft rotates, it drives the spiral rod to transport the colloid.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-6This utility model is a glue injection device for laminated glass, including a first assembly shell 1, a second assembly shell 2, a glue filling cylinder 3, and a glue injection nozzle 4. The second assembly shell 2 is bolted to the first assembly shell 1, and the glue filling cylinder 3 is threaded to the top of the first assembly shell 1. The interior of the first assembly shell 1 and the interior of the glue filling cylinder 3 are connected. The glue injection nozzle 4 is threaded to one end of the first assembly shell 1. A spiral rod 5 is provided inside the first assembly shell 1, and a stepper motor 6 is fixedly connected to the other end of the first assembly shell 1. A transmission mechanism for driving the spiral rod 5 to rotate is installed inside the first assembly shell 1. The control button on the handle of the first assembly shell 1 is wired to the stepper motor 6. The entire glue injection device is powered by a wire and a plug. The wired connection and the wire plug are existing technologies and are not specifically shown in the accompanying drawings.

[0020] A specific application of this embodiment is as follows: First, the adhesive raw material is loaded into the glue filling cylinder 3, which is threadedly connected to the first assembly shell 1. The stepper motor 6 is started, and the transmission mechanism drives the screw rod 5 to rotate, delivering the adhesive to the glue injection nozzle 4. The stepper motor 6 controls the rotation speed of the screw rod 5 to be in a fast or slow state by adjusting the speed, thereby controlling the delivery speed of the adhesive, achieving the glue injection steps of slow start (when the adhesive is at the bottom of the laminated glass) → fast in the middle (when the adhesive is in the middle of the laminated glass) → slow stop at the end (when the adhesive is at the top of the laminated glass). After a period of use, the second assembly shell 2 is removed, and the adhesive adhered to the surface of the screw rod 5 inside the first assembly shell 1 is cleaned, so that the glue injection device has the functions of automatic variable speed delivery of adhesive and convenient maintenance.

[0021] The transmission mechanism includes a rotating frame 7, a first positioning block 8, a second positioning block 9, and a positioning shell 10. The rotating frame 7 is fixedly connected to the inner wall of the first assembly shell 1, and the first positioning block 8 is rotatably connected to the rotating frame 7. The output shaft of the stepper motor 6 is fixedly connected to the second positioning block 9 located inside the first assembly shell 1. The two ends of the spiral rod 5 are fixedly connected to the positioning shells 10. One positioning shell 10 is bolted to the first positioning block 8, and the other positioning shell 10 is bolted to the second positioning block 9.

[0022] One specific application of this embodiment is as follows: Loosen the bolts on the surface of the positioning shell 10 to separate the positioning shell 10 from the first positioning block 8 and the second positioning block 9, clean and maintain the spiral rod 5, and after cleaning, place the spiral rod 5 inside the first assembly shell 1. The bolts firmly connect the first positioning block 8 and the second positioning block 9 to the positioning shell 10. When the output shaft of the stepper motor 6 rotates, it drives the spiral rod 5 to transport the colloid.

[0023] The positioning shell 10 has a concave design.

[0024] One specific application of this embodiment is that when disassembling the screw rod 5, the positioning shell 10 can be separated from the first positioning block 8 and the second positioning block 9 from one side. If the positioning shell 10 has a loop-shaped closed design, the screw rod 5 cannot be taken out normally.

[0025] Semicircular ring blocks 11 are symmetrically fixedly connected to the surfaces of the first assembly shell 1 and the second assembly shell 2. A first heating sleeve 12 is provided between the two semicircular ring blocks 11 and sleeved on the surfaces of the first assembly shell 1 and the second assembly shell 2. The charging cable part of the first heating sleeve 12 is existing technology and is not specifically drawn.

[0026] One specific application of this embodiment is that when the screw rod 5 is conveying the colloid, the first heating sleeve 12 generates heat energy to heat the colloid, ensuring the fluidity of the colloid and preventing the colloid from sticking to the surface of the screw rod 5.

[0027] A ring block 13 is symmetrically fixedly connected to the surface of the glue-filling cylinder 3. A second heating sleeve 14 is provided between the two ring blocks 13 and sleeved on the surface of the glue-filling cylinder 3. The charging cable part of the second heating sleeve 14 is existing technology and is not specifically drawn.

[0028] One specific application of this embodiment is as follows: during the process of the colloid entering the first assembly shell 1 from the inside of the colloid filling tube 3, the second heating sleeve 14 heats the colloid to ensure the fluidity of the colloid inside the colloid filling tube 3 and prevent it from sticking to the inner wall of the colloid filling tube 3.

[0029] The top of the glue-filling tube 3 has an injection port 15, and the injection port 15 has a sealing cap 16 inside.

[0030] One specific application of this embodiment is as follows: the sealing cap 16 is moved out of the injection port 15, the colloid delivery pipe is inserted into the colloid filling cylinder 3 through the injection port 15, and the colloid is continuously delivered. The stepper motor 6 works with the screw rod 5 to continuously deliver the colloid. The colloid filling cylinder 3 with the closed top is suitable for injecting colloid into small-sized laminated glass, while the colloid filling cylinder 3 with the open top is suitable for continuously delivering colloid and injecting colloid into large-sized laminated glass.

[0031] The top of the glue-filling cylinder 3 is symmetrically fixed with a positioning frame 17. The rectangular blocks on both sides of the sealing cover 16 are connected to the inside of the positioning frame 17, and the rectangular blocks on both sides of the sealing cover 16 are bolted to the top of the glue-filling cylinder 3.

[0032] One specific application of this embodiment is: the sealing cap 16 is brought close to the top of the glue-filling cylinder 3, and the rectangular blocks at both ends of the sealing cap 16 enter the positioning frame 17. The threaded holes on the surface of the rectangular blocks are aligned with the threaded holes at the top of the glue-filling cylinder 3, which facilitates the quick insertion of bolts and improves the assembly speed of the glue-filling cylinder 3 and the sealing cap 16.
