Description

Technical Field

[0001] The invention relates to the technical field of sealant filling, in particular to a filling process of a single-component sealant. Background Art

[0002] In the current sealant production and application field, the filling process is the key link between production and use, and its efficiency and precision directly affect the market competitiveness and user satisfaction of the product. The traditional one-component sealant filling process often uses a simple extrusion or pumping method to inject the sealant from the storage container into the glue container. However, this process has many shortcomings: 1. Slow filling speed: Due to the lack of effective scraping and squeezing mechanisms, traditional processes often rely on the fluidity and gravity of the sealant itself, resulting in a slow filling speed. This problem is particularly prominent in the filling process of single-component sealants, which are high-viscosity sealants.

[0003] 2. Serious material waste: During the filling process, sealants are easily attached to the inner wall of the container or the filling equipment, resulting in a large amount of material waste. These residual sealants not only increase production costs, but may also interfere with subsequent production processes.

[0004] Therefore, the market needs an efficient and low-residue sealant filling process to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to provide a filling process for a one-component sealant, which can achieve a high-efficiency, residue-free filling effect through a unique design concept and a fine step arrangement.

[0006] The above technical purpose of the present invention is achieved through the following technical scheme: A filling process of a one-component sealant comprises the following steps: S1. Prepare an elastic enclosure with openings at both ends and in a cylindrical shape, arrange a number of skeletons in a circular array on the elastic enclosure, each skeleton has a protrusion at the upper end, and a feeding pipe is set through any skeleton, and each skeleton is elastically hinged on the positioning frame, prepare a first telescopic cylinder, whose telescopic movable end is connected to a movable rod, and a piston is provided at the end of the movable rod and placed in the elastic enclosure, and a second telescopic cylinder corresponding to the protrusion is installed on the top of the piston, and a push rod is provided at the telescopic movable end of each second telescopic cylinder to be squeezed and matched with the protrusion, and a scraper is installed at the bottom of the piston through a connecting rod, and the edge of the scraper is in contact with the elastic enclosure and the skeleton; S2. Place the glue container under the elastic enclosure, and inject the single-component sealant through the feeding pipe to ensure that the liquid level is lower than the scraper; S3, controlling the scraper sheet to move downward by the first telescopic cylinder to scrape the elastic enclosure and the frame; S4, the scraper continues to move downward, completely squeezing the sealant out of the elastic enclosure and dropping it into the glue container; S5, controlling the push rod to extend through the second telescopic cylinder; S6, the piston is controlled to move upward by the first telescopic cylinder, and the push rod pushes the convex block to flip the frame, so that the upper opening of the elastic enclosure is expanded and the lower opening is contracted; S7, the piston continues to move upward, and the scraper sheet simultaneously passes through the contracted opening below the elastic enclosure and is squeezed, and the glue retained on it is squeezed out and falls into the glue container.

[0007] In some embodiments, in step S1, the elastic enclosure adopts a double-layer elastic structure, and the frame is arranged in the interlayer. The specific assembly steps include erecting the inner enclosure, fixing the frame, putting on the outer enclosure, and injecting glue for curing.

[0008] In some embodiments, in step S1, the lower ends of each skeleton are bent so that the lower ends are brought together.

[0009] In some embodiments, in step S1 , the scraper blade is designed to be a trumpet-shaped structure with its opening facing downward.

[0010] In some embodiments, in step S1 , the first telescopic cylinder and the positioning frame are both disposed on a robotic arm that can move in the XYZ axis directions.

[0011] In some embodiments, in step S3, after the scraper moves below the feeding pipe, air is inflated and pressurized into the elastic enclosure through the feeding pipe.

[0012] In some embodiments, in step S1, a filling metering mechanism is provided inside the elastic enclosure, including a metering sensor and a control unit, to monitor and control the filling amount and accuracy of the sealant in real time.

[0013] In some embodiments, step S8 is also included, using a cleaning agent to clean the inside of the elastic enclosure and the scraper sheet, rinsing with clean water, and drying for next use.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The present invention realizes rapid filling of sealant by adopting elastic enclosure and skeleton structure and combining precise control of the first telescopic cylinder. During the scraping and squeezing process, the sealant is quickly and completely squeezed out of the elastic enclosure and falls into the glue container, thereby greatly improving the filling speed.

[0015] The scraper blade of the present invention is cleverly designed and closely cooperates with the elastic enclosure and the frame, and can fully scrape the inner wall of the device during the filling process, effectively reducing the adhesion of the sealant. At the same time, through the strong action of the extrusion step, the sealant retained on the scraper blade is completely squeezed out, ensuring the filling without residue, thereby greatly reducing material waste.

[0016] In summary, the one-component sealant filling process of the present invention achieves a highly efficient and residue-free filling effect through its unique design concept and sophisticated step arrangement. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] like Figure 1-7 As shown, this embodiment provides a filling process of a one-component sealant, which includes the following steps: S1, such as Figure 1 As shown, an elastic enclosure 10 with both ends open and in a cylindrical shape is prepared, and a plurality of skeletons 8 are arranged in a circular array on the elastic enclosure 10, and a convex block 11 is provided at the upper end of each skeleton 8, and then a feeding pipe 9 is provided through any skeleton 8, and each skeleton 8 is elastically hinged on a positioning frame 12, and then a first telescopic cylinder 1 is prepared, and a movable rod 2 is provided at the telescopic movable end of the first telescopic cylinder 1, and a piston 3 is provided at the end of the movable rod 2, and the piston 3 is arranged in the elastic enclosure 10, and then a second telescopic cylinder 4 corresponding to the number and position of the convex block 11 is installed on the top of the piston 3, and a push rod 5 is provided on the telescopic movable end of each second telescopic cylinder 4, and the push rod 5 is pressed and matched with the convex block 11, and a scraper sheet 7 is installed at the bottom of the piston 3 through a connecting rod 6, and it is ensured that the edge of the scraper sheet 7 is in contact with the elastic enclosure 10 and the skeleton 8; The elastic hinge design of the skeleton 8 and the positioning frame 12 allows the skeleton 8 to be flexibly flipped as needed during the filling process to adjust the size of the upper and lower openings of the elastic enclosure 10, and after the external force on the skeleton 8 is removed, the skeleton 8 can be quickly reset, and the size of the upper and lower openings of the elastic enclosure 10 will also be restored to be consistent.

[0024] S2, such as Figure 2 As shown, the glue container is placed just below the elastic enclosure 10, and then the single-component sealant is injected into the elastic enclosure 10 through the feeding pipe 9, and it is ensured that the liquid level of the single-component sealant is below the scraper sheet 7; S3, such as Figure 3 As shown, the scraper sheet 7 is controlled to move downward by the first telescopic cylinder 1, during which the scraper sheet 7 scrapes the elastic enclosure 10 and the frame 8; S4, such as Figure 4As shown, as the scraper blade 7 continues to move downward, the single-component sealant is completely squeezed out from the elastic enclosure 10 together with the scraper blade 7, and the squeezed sealant falls into the sealant container. This step uses the elastic enclosure 10 and the skeleton 8 structure, combined with the precise control of the first telescopic cylinder 1, to achieve rapid and low-residue filling of the sealant. This method not only improves the filling speed, but also reduces the material waste during the filling process. The ingenious design of the scraper 7 and its close cooperation with the elastic enclosure 10 and the frame 8 enable the scraper 7 to fully scrape the inner wall of the device during the filling process, effectively reducing the adhesion of the sealant.

[0025] S5, such as Figure 5 As shown, the push rod 5 is controlled by the second telescopic cylinder 4 to extend toward the direction of the protrusion 11; S6, such as Figure 6 As shown, the piston 3 is controlled to move upward by the first telescopic cylinder 1 until the push rod 5 pushes the protrusions 11 one by one. At this time, the ends of the frames 8 provided with the protrusions 11 will flip in the direction away from each other, thereby causing the upper opening of the elastic enclosure 10 to expand and the lower opening to shrink. At the same time, it is necessary to ensure that the scraper sheet 7 is still outside the elastic enclosure 10 at this time; S7, such as Figure 7 As shown, as the piston 3 continues to move upward, the scraper sheet 7 will move upward synchronously and pass through the opening below the elastic enclosure 10 which remains in a contracted state. During this period, the scraper sheet 7 is squeezed, and the glue retained thereon will be squeezed out and fall into the glue container. In this step, the scraper sheet 7 is strongly squeezed, and the sealant retained thereon is completely squeezed out, ensuring that there is no residue in the filling.

[0026] In this process, the elastic enclosure 10 is elastically hinged on the positioning frame 12 through the skeleton 8, and the second telescopic cylinder 4 corresponding to the protrusion 11 is installed on the piston 3. The single-component sealant is injected into the elastic enclosure 10 through the feeding pipe 9, and the liquid level is ensured to be lower than the scraper 7. Then, the scraper 7 is controlled to move downward by the first telescopic cylinder 1, during which the scraper 7 scrapes the elastic enclosure 10 and the skeleton 8 to scrape off the sealant attached to the inner wall. As the scraper 7 continues to move downward, the sealant is completely squeezed out of the elastic enclosure 10 and falls into the glue container. After that, the second telescopic cylinder 4 controls the push rod 5 to push open the protrusion 11, so that the end of the skeleton 8 with the protrusion 11 is turned in a direction away from each other, causing the upper opening of the elastic enclosure 10 to expand and the lower opening to shrink. At this time, the scraper 7 is still outside the elastic enclosure 10, ready for the subsequent extrusion step. In the process of the piston 3 continuing to move upward, the scraper 7 moves upward synchronously and passes through the opening below the elastic enclosure 10 that remains in a contracted state. During this period, the scraper sheet 7 is subjected to strong squeezing, and the sealant retained on it is completely squeezed out and falls into the glue container. This squeezing step not only ensures the thoroughness and residue-free nature of filling, but also improves the sealing performance and appearance quality of the product. According to the above technical scheme, the one-component sealant filling process of the present invention achieves efficient and residue-free filling effects through its unique design concept and fine step arrangement, and brings many technical advantages and economic benefits.

[0027] In some embodiments, in step S1, the elastic enclosure 10 adopts a double-layer elastic structure, and the frame 8 is arranged in the interlayer thereof. The assembly steps of the elastic enclosure 10 and the frame 8 are as follows: a. Place the inner layer of the elastic enclosure 10 upright, arrange it in a preset circular array, and fix the skeletons 8 one by one to the outer wall of the inner elastic enclosure 10 to ensure that the skeletons 8 are evenly distributed and can effectively support the structure of the inner enclosure; b. Put the outer elastic enclosure 10 on the outer part of the inner elastic enclosure 10 and the frame 8 to ensure that the two layers of enclosures fit tightly and the frame 8 is firmly clamped in the interlayer of the two layers of enclosures. During this process, special attention should be paid to keeping the openings of the two layers of enclosures aligned for subsequent filling operations; c. Inject glue into the interlayer and squeeze out the bubbles in the interlayer. After the glue is cured, the assembly of the elastic enclosure 10 and the frame 8 is completed.

[0028] In some embodiments, Figure 1-7As shown, in step S1, the lower ends of the skeletons 8 are bent so that the lower ends of the skeletons 8 are brought together. This design allows the scraper sheet 7 to pass through the opening in the contracted state below the elastic enclosure 10 in step S7. Due to the design of the lower ends of the skeletons 8 being brought together, the opening is more compact and uniform when contracted, thereby facilitating the passage of the scraper sheet 7. At the same time, this design also makes the extrusion effect on the scraper sheet 7 during the passage process more intense and uniform, which helps to completely squeeze out the sealant retained on it.

[0029] In some embodiments, Figure 1-7 As shown, in step S1, the scraper sheet 7 is designed to be a trumpet-shaped structure with the opening facing downward. The technical effect of this design is mainly reflected in step S7. When the scraper sheet 7 passes through the opening under the elastic enclosure 10 that remains in a contracted state, its trumpet-shaped structure causes the scraper sheet 7 to be subjected to a stronger extrusion effect. This extrusion not only helps to completely squeeze out the sealant retained on the scraper sheet 7, but also ensures that the filling is residue-free. At the same time, the trumpet-shaped structure also makes the extrusion process more uniform and smooth, avoiding sealant residue or leakage caused by uneven extrusion. The whole process is similar to the process of folding an umbrella.

[0030] In some embodiments, in step S1, the first telescopic cylinder 1 and the positioning frame 12 are both arranged on a mechanical arm that can move in the XYZ axis direction. This makes the entire filling system extremely flexible. The user can easily adjust the position of the elastic enclosure 10 and the scraper sheet 7 according to actual needs to adapt to different specifications and shapes of glue-filled containers, thereby greatly broadening the application range of the filling process.

[0031] In some embodiments, in step S3, after the scraper blade 7 moves to the bottom of the feeding pipe 9, the feeding pipe 9 is used to inflate the elastic enclosure 10 to pressurize the elastic enclosure 10. By inflating and pressurizing the elastic enclosure 10, the extrusion process of the sealant from the elastic enclosure 10 can be accelerated. Under the action of the air pressure, the sealant will flow to the glue container faster, thereby increasing the filling speed and shortening the production cycle.

[0032] In some embodiments, in step S1, a filling metering mechanism is also provided inside the elastic enclosure 10, which includes a metering sensor and a control unit connected thereto. The metering sensor is used to monitor the liquid level or quality of the sealant in the elastic enclosure 10 in real time, and transmit these data to the control unit in real time. The control unit accurately controls the amount of glue fed into the feed pipe 9 and the telescopic stroke of the first telescopic cylinder 1 according to the preset filling volume and the data of the sensor, so as to ensure that the amount of sealant filled each time is accurate. This design not only improves the accuracy and efficiency of filling, but also reduces material waste and improves product quality. At the same time, it also enhances the automation degree and data traceability of the filling process, providing users with a better and more convenient user experience.

[0033] In some embodiments, step S8 is also included. First, a cleaning agent is used to spray or soak the inside of the elastic enclosure 10 and the scraper sheet 7 to soften and remove residues; then, they are rinsed with clean water to ensure that no cleaning agent remains; finally, a drying device is used to dry the elastic enclosure 10 and the scraper sheet 7 for next use.

[0034] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
