Description

Technical Field

[0001] This application relates to the field of footwear processing technology, specifically to a quantitative device for adding plasticizer to PVC injection molded shoe materials. Background Technology

[0002] PVC (polyvinyl chloride) materials are widely used in footwear manufacturing due to their excellent plasticity, abrasion resistance, and cost advantages, especially in injection-molded shoes, where injection molding allows for efficient mass production. During PVC injection molding, a certain proportion of plasticizer is typically added to improve its processing performance and the flexibility of the finished product. However, the amount of plasticizer added has a significant impact on the performance of the final product; too much or too little will lead to a decline in material properties. Therefore, precise control of plasticizer addition during production is crucial.

[0003] Currently, the addition of plasticizers on PVC injection molded shoe material production lines presents challenges such as unsanitary operating environments and potential pollution. Furthermore, plasticizers have a certain degree of viscosity and poor fluidity at room temperature, making them prone to adhering to the inner walls of containers, resulting in inaccurate metering and difficulties in subsequent cleaning. Summary of the Invention

[0004] The technical problem to be solved by this application is to overcome the existing defects and provide a quantitative device for adding plasticizer to PVC injection molded shoe materials, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution: a metering device for adding plasticizer to PVC injection molded shoe material, comprising a support frame, a top horizontal support frame at the upper end of the support frame, an installation frame on one side of the top horizontal support frame, vertical support plates at both ends of the installation frame, a transition seat rotatably connected to the lower end of the vertical support plate, the transition seat being disposed on a measuring cylinder placement seat, a V-shaped groove for placing a measuring cylinder being disposed between the measuring cylinder placement seats, a support horizontal plate at the rear side of the top horizontal support frame, an installation bracket at one end of the support horizontal plate, a tilting cylinder at one end of the installation bracket, a transition support connected to the telescopic end of the tilting cylinder, the transition support being connected to a rotating shaft disposed in the measuring cylinder placement seat, a heating device being disposed below the measuring cylinder placement seat, a cap being disposed correspondingly at the measuring cylinder inlet, and the cap being disposed correspondingly in the intermediate support plate between the vertical support plates.

[0006] As a preferred technical solution of this application, a telescopic cylinder is provided at the upper end of the top cross brace, and the telescopic end of the telescopic cylinder passes through the middle support plate and is connected to a cover.

[0007] As a preferred technical solution of this application, the edge of the cap has a conical structure and a concave groove is provided on the cap, which is interference-fitted with the metering barrel.

[0008] As a preferred technical solution of this application, the measuring cylinder placement seat includes a side support plate, a threaded shaft and an intermediate locking seat. The threaded shaft is threaded in the threaded hole of the side support plate, and its other end is disposed in the intermediate locking seat.

[0009] As a preferred technical solution of this application, a flexible pad is provided on the inner edge of the V-shaped groove in the middle of the side support plate.

[0010] As a preferred technical solution of this application, the measuring barrel is provided with a scale.

[0011] As a preferred technical solution of this application, the end of the mounting bracket is connected to the tilting cylinder via a rotating shaft.

[0012] Compared with existing technologies, the beneficial effects of this application are as follows: The cap corresponding to the feed inlet of the metering barrel, and the cone-shaped structure and concave groove design with interference fit between the cap and the metering barrel, ensure the sealing of the plasticizer during the metering process, effectively preventing plasticizer spillage and external contamination. This not only protects the health of operators but also avoids pollution of the production environment, meeting the requirements of modern industry for clean production. Furthermore, the automatic opening and closing of the cap is controlled by a telescopic cylinder. When the cap moves upward, its edge scrapes against the inner wall of the metering barrel, cleaning the plasticizer remaining on the cup wall into the concave groove inside the cap, achieving a self-cleaning function. The plasticizer collected in the concave groove can also be recycled and reused, improving utilization efficiency. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application (for ease of description and understanding, hereinafter referred to as...), Figure 2 (The above is described above). All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0020] Please see Figure 1-5 This embodiment provides a quantitative device for adding plasticizer to PVC injection molded shoe materials. The device mainly includes a support frame 6, a top horizontal support frame 2, a mounting frame 11, a vertical support plate 5, an adapter seat 10, a measuring cylinder placement seat, a measuring cylinder 4, a flipping cylinder 13, an adapter support 14, a cover 15, and a middle support plate 3.

[0021] The support frame 6 serves as the base of the entire device, with a top cross brace 2 at its upper end to provide a mounting position for the mounting frame 11. To facilitate the movement of the device, the bottom of the support frame 6 can also be equipped with casters with locking mechanisms, allowing the device to be moved flexibly and conveniently when needed, and to be stably fixed after positioning.

[0022] A mounting frame 11 is provided on one side of the top horizontal support frame 2. Vertical support plates 5 are provided at both ends of the mounting frame 11. A transition seat 10 is rotatably connected to the lower end of the vertical support plate 5. The transition seat 10 is set on the measuring cylinder placement seat. A V-shaped groove for placing the measuring cylinder 4 is provided between the measuring cylinder placement seats. The V-shaped groove can ensure the stable placement of the measuring cylinder 4.

[0023] The measuring cylinder placement seat includes a side support plate 9, a threaded shaft 7, and an intermediate locking seat 8. The threaded shaft 7 is threaded into the threaded hole of the side support plate 9, and its other end is located in the intermediate locking seat 8. This structure allows the measuring cylinder placement seat to be adjusted and fixed according to measuring cylinders 4 of different sizes, simplifying the process of placing and taking out measuring cylinders 4 and improving the convenience of use.

[0024] A flexible pad is provided on the inner edge of the V-shaped groove in the middle of the side support plate 9. The flexible pad is used to buffer the contact pressure between the metering barrel 4 and the V-shaped groove to prevent damage to the outer wall of the metering barrel 4.

[0025] The rear side of the top cross brace 2 is provided with a support plate. One end of the support plate is provided with a mounting bracket 12. One end of the mounting bracket 12 is also provided with a tilting cylinder 13. The end of the telescopic end of the tilting cylinder 13 is connected to a transition support 14. The transition support 14 is connected to a rotating shaft provided in the measuring cylinder placement seat.

[0026] When the tilting cylinder 13 is activated, it tilts the metering container 4, pouring the metered plasticizer into the injection molding machine hopper. The metering container 4 has clear graduations, facilitating manual observation and calibration, allowing for precise control of its contents. Furthermore, a heating device can be added to the bottom of the metering container 4 to maintain the plasticizer's fluidity. The inner wall of the metering container 4 is also coated with an anti-stick coating to prevent the plasticizer from adhering to the container wall.

[0027] A cover 15 is provided at the feed inlet of the metering barrel 4. The cover 15 is located in the middle support plate 3 between the vertical support plates 5 to ensure the sealing between the cover 15 and the feed inlet of the metering barrel 4, and to prevent the plasticizer from overflowing or being contaminated by the outside during the metering process.

[0028] After the set plasticizer is added into the metering barrel 4, the cap 15 seals the metering barrel 4, the heating device is started to increase its fluidity, the cap 15 is opened, the tilting cylinder 13 is shortened, the angle of the adapter support 14 is adjusted, and the metering barrel 4 is tilted, and the plasticizer is poured into the injection molding machine hopper.

[0029] A telescopic cylinder 1 is installed at the upper end of the top cross support 2. The telescopic end of the telescopic cylinder 1 passes through the middle support plate 3 and is connected to a cover 15. The edge of the cover 15 is tapered and a concave groove is provided on the cover 15. It is interference-fitted with the metering barrel 4.

[0030] By extending and retracting the telescopic cylinder 1, the cap 15 can be automatically opened and closed. At the same time, there is an interference fit between the cap 15 and the metering container 4, and its edge can be closely attached to the inner wall of the metering container 4. When the cap 15 moves upward, it can clean the cup wall after the plasticizer is poured out. The plasticizer on the cup wall flows into the concave groove inside the cap 15 to achieve self-cleaning. The plasticizer in the concave groove can be recycled and reused.

[0031] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
