Description
Technical Field
[0001] The utility model relates to the technical field of foam production, in particular to a continuous pre-expander for foam production. Background Art
[0002] Foam products are materials with light weight, porous structure and good heat insulation performance, and are widely used in fields such as construction, packaging, transportation, heat preservation, etc. The raw materials of foam products are mainly polymer materials such as polyurethane and polyethylene, as well as auxiliary materials such as catalysts, foaming agents and surfactants. The processing technological process of foam products mainly includes steps such as raw material preparation, foaming, curing, molding, and post-treatment.
[0003] When foam is produced and manufactured, foaming is the core link in the processing of foam products, that is, the raw materials are put into the pre-expansion cylinder, and mainly carried out in two ways: physical foaming and chemical foaming. Physical foaming is to mix gas into the raw materials by means of pressurization or cooling to form foam; chemical foaming is to add chemical substances such as foaming agents to generate gas under conditions such as heating to promote the expansion of the raw materials. No matter which foaming method is used, after foaming, a large amount of foam is easily attached to the inner wall of the pre-expansion cylinder and is difficult to clean. Most of the existing ones are cleaned by manual cleaning, but the work efficiency is low and the cleaning degree is low. It is necessary to design a continuous pre-expander for foam production to solve the above-mentioned problems. Summary of the Utility Model
[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art, and to propose a continuous pre-expander for foam production.

The rotating shaft of the motor penetrates through the middle part of the upper end of the fixed disk and is fixedly connected to the middle part of the upper end of a rotating disk. The outer side of the bottom end of the rotating disk is fixedly connected with a connecting disk. The bottom end of the connecting disk is fixedly connected with a cleaning rod. A cleaning brush is arranged on the outer side of the cleaning rod.
[0007] Through the above technical solution, the motor drives the rotating disk to rotate, so that the cleaning rod and the cleaning brush rotate inside the pre-expansion cylinder to clean the inner wall of the pre-expansion cylinder, clean the foam attached to the inner wall of the pre-expansion cylinder, and at the same time, the cleaning efficiency is relatively high.
[0008] Furthermore, the shape of the cleaning rod fits the inner shape of the pre-expansion cylinder, and the cleaning brush closely adheres to the inner wall of the pre-expansion cylinder.
[0009] Through the above technical solution, it is convenient for the cleaning brush to clean the inner wall of the pre-expansion cylinder thoroughly, avoiding omission.
[0010] Furthermore, a first fixing frame is fixedly connected to the outer side of the bottom end of the fixing plate, a second fixing frame is fixedly connected to the outer bottom end of the pre-expansion cylinder, and a plurality of support rods are equidistantly arranged between the first fixing frame and the second fixing frame;
[0011] Through the above technical solution, the fixing plate can be fixed at the upper part of the pre-expansion cylinder.
[0012] Furthermore, a feeding cylinder is fixedly connected to the middle part of the upper right side of the fixing plate, and a circular opening is arranged at the position of the feeding cylinder on the fixing plate;
[0013] Through the above technical solution, it is convenient to feed materials into the pre-expansion cylinder.
[0014] Furthermore, a special-shaped opening is arranged on the right side of the rotating disc;
[0015] Through the above technical solution, when the special-shaped opening overlaps with the circular opening, it is convenient for feeding. At the same time, the range of the special-shaped opening is relatively large, increasing the overlapping range with the circular opening.
[0016] Furthermore, a rotating groove is arranged at the bottom of the fixing plate, a rotating sleeve is arranged at the upper end of the rotating disc, and the rotating sleeve rotates inside the rotating groove;
[0017] Through the above technical solution, when the motor drives the rotating disc to rotate, the rotating sleeve arranged on the upper part of the rotating disc rotates inside the rotating groove, which is convenient for increasing the stability when the rotating disc rotates and can play a guiding role.
[0018] Furthermore, a connecting groove is arranged at the bottom of the connecting plate;
[0019] Through the above technical solution, it is convenient to fix the connecting plate and the cleaning rod.
[0020] The utility model has the following beneficial effects:
[0021] 1. In the utility model, the motor drives the rotating disc to rotate at the bottom of the fixing plate, and the rotating sleeve arranged on the upper part of the rotating disc rotates inside the rotating groove, so that the cleaning rod and the cleaning brush rotate inside the pre-expansion cylinder to clean the inner wall of the pre-expansion cylinder. It can not only clean the foam attached to the inner wall of the pre-expansion cylinder thoroughly, but also has a high cleaning efficiency. By continuously driving the cleaning rod to rotate by the motor, the cleaning degree is relatively high, avoiding the problems of uncleanliness and low efficiency caused by manual cleaning.
[0022] 2. In the present utility model, the motor starts the rotation of the rotating disk, causing the cleaning rod to rotate. This is simple, convenient, and easy to control. At the same time, the fixed disk is fixed by the first fixing frame, the second fixing frame, and the support rod, which facilitates the installation of the device outside the pre-expansion cylinder.
