Description

Technical Field

[0001] The utility model relates to the technical field of sponge processing, in particular to a sponge foaming box which is easy to operate. Background Art

[0002] Sponge is a type of polyurethane foam, classified as a soft polyurethane foam. Due to its porous honeycomb structure and excellent softness, elasticity, water absorption, and water resistance, it is widely used in industries such as sofas, mattresses, clothing, and flexible packaging. Sponge production generally utilizes a box-type foaming process, where various raw materials are rapidly added to a foaming box under high-speed stirring. Chain growth, foaming, cross-linking, and curing reactions occur within the foaming box, completing the sponge production process. The foaming box is required during the sponge processing process, where workers manually inject the liquid raw materials for sponge production into the foaming box. The liquid raw materials then foam the sponge within the box. Once the sponge is foamed, workers remove the sponge using specialized tools.

[0003] Regarding the above-mentioned related technologies, the inventors found that during the process of foaming the liquid raw material into sponge, the sponge generates a large expansion force, which causes a large static friction between the foamed sponge and the foaming box. Workers need to spend a lot of effort to remove the sponge from the forming box, which increases the labor intensity of the workers and reduces the convenience of operation. Utility Model Content

[0004] The main technical problem solved by the utility model is to provide a sponge foaming box that is easy to operate. By setting a draft angle on the inner wall of the rectangular cylinder and the U-shaped stripper plate assembly can be extended into the inner cavity of the rectangular cylinder to push the sponge, the labor intensity of workers in removing the sponge is reduced and the convenience of operation is improved.

[0005] In order to solve the above technical problems, a technical solution adopted by the present invention is: to provide a sponge foaming box with convenient operation, comprising: a rectangular feeding tray and a rectangular cylinder arranged above the rectangular feeding tray, wherein the inner wall of the rectangular cylinder is provided with a draft angle, the lower end opening of the rectangular cylinder is larger than the upper end opening, a rectangular mounting frame assembly is sleeved on the outer side of the upper end of the rectangular cylinder, the lower end of the rectangular mounting frame assembly is fixedly connected to the rectangular feeding tray, and further comprising a lifting drive mechanism, wherein the lifting drive mechanism is connected to the rectangular cylinder and is suitable for driving the rectangular cylinder to move in the vertical direction;

[0006] A U-shaped stripping plate assembly that can extend into the rectangular cylinder is connected to the top of one side of the rectangular installation frame assembly.

[0007] By adopting the above technical solution, when in use, the lifting drive mechanism is operated to drive the rectangular cylinder to move upward to a certain height, the worker injects the liquid raw material of the sponge into the inner cavity of the rectangular distribution plate, and uses a scraper to scrape the liquid raw material so that the liquid raw material is quickly and evenly distributed in the inner cavity of the rectangular distribution plate. The lifting drive mechanism is operated to drive the rectangular cylinder to move downward and is tightly connected with the rectangular distribution plate. The liquid raw material in the rectangular distribution plate is foamed to form a sponge and is located in the inner cavity of the rectangular cylinder. When the sponge is foamed, the lifting drive mechanism is operated to drive the rectangular cylinder to move upward. Since the inner wall of the rectangular cylinder is provided with a draft mold The U-shaped stripping plate assembly moves relative to the rectangular cylinder, and the U-shaped stripping plate assembly extends into the inner cavity of the rectangular cylinder to push down the sponge, thereby achieving the purpose of taking the sponge out of the rectangular cylinder. This does not require much manual intervention from workers, reduces the labor intensity of workers, and improves the convenience of operation.

[0008] In a preferred example, the present invention can be further configured as follows: the draft angle is 0.5° to 1°.

[0009] By adopting the above technical solution, the inner wall of the rectangular cylinder has a certain inclination angle, which makes it easier for the sponge to fall off smoothly from the rectangular cylinder.

[0010] In a preferred example, the present invention can be further configured as follows: the rectangular mounting frame assembly includes a mounting frame body, two L-shaped rods are spaced apart and connected to both sides of the mounting frame body, and the ends of the horizontal sides of the L-shaped rods are connected to the rectangular cloth tray.

[0011] By adopting the above technical solution and using the L-shaped rod, the installation frame body is indirectly fixedly connected to the rectangular distribution tray.

[0012] In a preferred example, the present invention can be further configured as follows: the lifting drive mechanism includes two lifting drive components symmetrically connected to the front and rear sides of the rectangular cylinder, the lifting drive component includes a driving member and guide rails arranged on both sides thereof, and the inner wall of the mounting frame body is connected to the rectangular cylinder through the guide rails.

[0013] By adopting the above technical solution, the guide rail is connected between the rectangular cylinder and the installation frame body, and the driving member drives the rectangular cylinder to move up and down smoothly.

[0014] In a preferred example, the present invention can be further configured as follows: the driving member includes a rack, a gear and a fixed plate connected to a rectangular mounting frame assembly, a servo motor is mounted on the fixed plate, the output shaft of the servo motor is sleevedly connected to the gear, the gear is meshed with the rack, and the rack is vertically arranged and connected to the rectangular cylinder.

[0015] By adopting the above technical solution, the servo motor drives the gear to rotate, the gear drives the rack to move up and down, and the rack drives the rectangular cylinder to move up and down.

[0016] In a preferred example, the present invention can be further configured as follows: the U-shaped stripper plate assembly includes a U-shaped rod and a stripper plate, one end of the U-shaped rod is connected to the top of the rectangular mounting frame assembly, and the other end is connected to the stripper plate, and the stripper plate is located directly above the center of the rectangular feeding tray.

[0017] By adopting the above technical solution, when the lifting drive mechanism drives the rectangular cylinder to move, the stripping plate on the U-shaped rod contacts the top of the sponge, thereby pushing the sponge to fall off from the rectangular cylinder.

[0018] In a preferred example, the present invention can be further configured as follows: a rectangular fixing groove is provided on the top of the side wall of the rectangular distribution tray, and a sealing strip is provided in the rectangular fixing groove.

[0019] By adopting the above technical solution and setting the sealing strip, the sealing performance of the contact connection between the rectangular cylinder and the rectangular distribution plate is enhanced, preventing the sponge from extending outward from the gap between the rectangular cylinder and the rectangular distribution plate when foaming.

[0020] In summary, the present invention has at least one of the following beneficial technical effects:

[0021] 1. Since the inner wall of the rectangular cylinder is provided with a draft angle, the friction between the rectangular cylinder and the sponge gradually decreases during the rising process. Under the action of the gravity of the sponge, the sponge can fall off from the rectangular cylinder, thereby achieving the purpose of removing the sponge from the rectangular cylinder.

[0022] 2. During the rising process of the rectangular cylinder, the stripping plate on the U-shaped rod contacts the top of the sponge, thereby pushing the sponge to fall off from the rectangular cylinder, thereby achieving the purpose of taking the sponge out of the rectangular cylinder. This does not require much manual intervention from workers, reduces the labor intensity of workers, and improves the convenience of operation. BRIEF DESCRIPTION OF THE DRAWINGS
