Description

Technical Field

[0001] This utility model relates to the field of sealant production technology, and in particular to a sealant extrusion molding device that is easy to adjust. Background Technology

[0002] Sealants are generally used to fill gaps in structures to achieve a sealing effect. They also provide leak prevention, waterproofing, vibration damping, sound insulation, and heat insulation. Sealants are typically made from dry or non-drying viscous materials such as asphalt, natural or synthetic resins, and natural or synthetic rubber, combined with inert materials and auxiliary agents to create a sealing material that conforms to the shape of the sealing surface, does not easily flow, and has a certain degree of adhesion.

[0003] Currently, the production, inspection, and application of sealants require the use of extrusion molding devices to extrude the sealant. This is especially true during sealant production and inspection, where the sealant is extruded and applied to glass or other testing equipment. During this application process, operators often hold the extrusion molding device and move it slowly to ensure even sealant application. However, this movement is often inconsistent, resulting in uneven sealant application. This negatively impacts the sealant performance testing results and creates challenges in sealant production.

[0020] The present invention will now be further described with reference to the accompanying drawings.

[0021] An easily adjustable sealant extrusion molding device includes a horizontally arranged sealant storage tube 1 with a hollow structure. One end of the sealant storage tube 1 is equipped with an extrusion assembly, and the other end of the sealant storage tube 1 is detachably and fixedly connected to a sealant head 2. Four wheels 3 are installed at the four corners of the bottom of the sealant storage tube 1, one of which is a self-driving wheel. By installing wheels 3 at the bottom of the sealant storage tube 1, and designating one as a self-driving wheel, the self-driving wheel can move under the drive of its connected motor, thereby driving the other wheels 3 to move. This improves the stability of the device during the sealant application process and reduces errors caused by manual sealant application.

[0022] The device also includes a drive assembly for driving the extrusion assembly. The drive assembly includes a horizontally positioned electric push rod 4, which is fixedly connected to the top of the glue reservoir 1. The piston rod of the electric push rod 4 drives the extrusion assembly to reciprocate. In use, the electric push rod 4 is activated, and its piston rod drives the extrusion assembly to reciprocate, thereby pushing the sealant in the glue reservoir 1 towards the glue head 2 until the sealant is extruded from the glue head 2, achieving sealant application. The arrangement of the traveling wheels 3 and the drive assembly allows the device to move at a more uniform speed under the action of the self-driven traveling wheels. The drive assembly also allows the electric push rod 4 to push the extrusion assembly at a uniform speed, resulting in more uniform and consistent sealant application, thus improving the accuracy of sealant inspection. In use, the self-driven traveling wheels can also be turned off as needed, and the device can be handheld for sealant application.

[0023] The device can power the self-driving wheels and electric push rod 4 via a power cord, or it can power the self-driving wheels and electric push rod 4 via a battery installed on the rubber storage tube 1. The circuit connections are all existing technologies and will not be described in detail here.

[0024] In another embodiment, the extrusion assembly includes a push plate 5 adapted to the cavity of the glue reservoir 1. The push plate 5 is slidably connected inside the glue reservoir 1. A horizontally arranged push rod 6 is fixedly connected to the side of the push plate 5 away from the glue head 2. The push rod 6 extends to the outside of the glue reservoir 1, and a vertically arranged connecting plate 7 is fixedly connected to the end of the push rod 6. The connecting plate 7 is fixedly connected to the piston rod end of the electric push rod 4. The push rod 6 is connected to the electric push rod 4 through the connecting plate 7. When the electric push rod 4 is activated, the piston rod end of the electric push rod 4 drives the push rod 6 to reciprocate through the connecting plate 7, thereby completing the extrusion action.

[0025] In another embodiment, a connector 19 is fixedly connected to one end of the glue reservoir tube 1 near the glue head 2. The outer side wall of the connector 19 is provided with external threads, and the inner side wall of the glue head 2 is provided with internal threads. The glue head 2 and the glue reservoir tube 1 are detachably and fixedly connected by threads, which facilitates the replacement of the glue head 2, so as to achieve the application of sealant of different widths on surfaces such as glass. At the same time, it also facilitates the cleaning of the inside of the glue reservoir tube 1.

[0026] In another embodiment, a steering head 8 is threadedly connected to the connection port 19. The steering head 8 is a hollow structure with open ends, and the adhesive head 2 is threadedly connected to the steering head 8. The steering head 8 is arc-shaped, and its ends can face different directions. The adhesive outlet end 11 of the adhesive head 2 faces the same direction as the end of the steering head 8. The steering head 8 facilitates adjustment of the sealant application position, allowing the sealant to be applied to glass located at different positions on the device, thus improving the device's applicability. Furthermore, the threads of the steering head 8 and the connection port 19 are identical, allowing the adhesive head 2 to be directly connected to the connection port 19 or to the steering head 8, providing diverse options for sealant application.

[0027] In another embodiment, a vertically arranged telescopic tube 9 is installed on the top of the traveling wheel 3, and the top of the telescopic tube 9 is fixedly connected to the glue storage tube 1. The telescopic tube 9 can be manually or electrically operated, which is prior art and will not be described in detail here. In use, after the glue head 2 is installed on the steering head 8, there may be a small height difference between the position to be coated and the glue head 2. To ensure the coating effect, the height of the glue storage tube 1 is adjusted by the telescopic tube 9, thereby adjusting the height between the glue head 2 and the position to be coated and improving the coating accuracy.

[0028] In another embodiment, the glue head 2 is conical and has a hollow structure with open ends. The end of the glue head 2 near the glue storage tube 1 is designated as the connecting end 10, and the other end is designated as the dispensing end 11. An adjusting block 12 is detachably and fixedly connected inside the glue head 2. The adjusting block 12 has an arc-shaped structure, with its arc surface abutting against and fitting against the inner wall of one side of the glue head 2. The bottom of the adjusting block 12 is flat. A gap is formed between the flat surface of the adjusting block 12 and the inner wall of the other side of the glue head 2, and this gap is designated as a flow cavity 13. The end of the adjusting block 12 is flush with the dispensing end 11 to adjust the open area of ​​the dispensing end 11 of the glue head 2. The flow cavity 13 is connected to the dispensing end 11 of the glue head 2. In use, the sealant enters the flow cavity 13 of the glue head 2 through the glue storage tube 1, and then reaches the outside of the glue head 2 through the open end 11, thus achieving sealant application. In addition, the device is equipped with adjustment blocks 12 of different specifications. The height of the end of the adjustment block 12 near the glue outlet 11 is denoted as H. The height H of the end of the adjustment block 12 of different specifications is different. By replacing the adjustment block 12, the end of the adjustment block 12 can block different areas of the glue outlet 11, thereby adjusting the thickness of the sealant extruded by the device.

[0029] In another embodiment, a mounting hole is provided on the outer side wall of the rubber head 2, and a threaded hole adapted to the mounting hole is provided on the adjusting block 12. The end of the bolt 14 passes through the mounting hole and is threadedly connected to the threaded hole. The rubber head 2 and the adjusting block 12 are detachably fixedly connected by the bolt 14. The bolt 14 facilitates the fixing of the position of the adjusting block 12.

[0030] In another embodiment, the top of the glue reservoir 1 is connected to a vertically arranged glue injection tube 15. The top of the glue injection tube 15 is tapered, and a glue injection plug (not shown in the figure) adapted to the glue injection tube 15 is detachably and fixedly connected to the glue injection tube 15. Before glue injection, the glue injection plug is opened, and the sealant is injected into the glue reservoir 1. After the glue injection is completed, the glue injection plug is inserted, and the position of the glue injection plug is fixed by bolt 14 to prevent the sealant from being squeezed out through the glue injection tube 15.

[0031] In another embodiment, an end cap 16 is fixedly connected to the end of the glue storage tube 1 away from the glue head 2. The end cap 16 has a sliding hole adapted to the push rod 6, and a rubber ring 17 is fixedly connected inside the sliding hole. The push rod 6 is slidably connected to the rubber ring 17. Buffer pads 18 are fixedly connected to both sides of the end cap 16. The rubber ring 17 reduces friction and damage to the end cap 16 caused by the sliding of the push rod 6, and also improves the sealing at the sliding hole. During use, lubricating oil can be applied to the inner wall of the rubber ring 17 to improve the smoothness of the sliding between the push rod 6 and the rubber ring 17. Simultaneously, the buffer pads 18 on both sides of the end cap 16 reduce the impact force on the end cap 16 when the connecting plate 7 and the push plate 5 strike it, extending the service life of the device.

[0032] In another embodiment, a buffer pad 18 is also fixedly connected to the inner wall of the glue storage tube 1 near the connection port 19, so as to reduce the impact force of the push plate 5 on the glue storage tube 1 and extend the service life of the device.

[0033] Instructions for use: When using, select an adjustment block 12 with a suitable height H as needed, and fix the adjustment block 12 inside the glue head 2 with bolts 14. Then, thread the steering head 8 to the connection port 19, and thread the glue head 2 to the steering head 8. Adjust the height of the telescopic tube 9 so that the glue outlet end 11 of the glue head 2 is at the same height as the position to be coated. Start the self-driving wheels. Under the action of the self-driving wheels, the wheels 3 drive the glue storage tube 1 to move. At the same time, start the electric push rod 4. The piston rod end of the electric push rod 4 pushes the push rod 6, so that the push rod 6 drives the push plate 5 to move closer to the glue head 2, thereby realizing the extrusion and coating of sealant.

[0034] The above embodiments are not intended to limit the shape, material, structure, etc. of this utility model in any way. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of this utility model.
