Description

Technical Field

[0001] The invention relates to the technical field of pulp molding production, in particular to a device for facilitating cleaning of dirt on a reciprocating hot pressing mold in pulp molding production. Background Art

[0002] As the problem of dirt on the surface of the reciprocating hot pressing mold in the pulp molding production process becomes increasingly prominent, in order to improve production efficiency and ensure product quality, it is urgent to design an efficient cleaning device. The device aims to solve the problems of low efficiency and incomplete cleaning of traditional cleaning methods, and improve cleaning efficiency, ease of operation and safety. In the pulp molding production process, the reciprocating hot pressing mold is a common equipment used to shape and process pulp. However, during long-term operation, dirt and stains are easily accumulated on the surface of the hot pressing mold, resulting in reduced production efficiency, reduced product quality, and even possible damage to the hot pressing mold. In order to solve this problem, it is necessary to design a device for cleaning dirt and stains on the reciprocating hot pressing mold during pulp molding operation.

[0003] The existing reciprocating machine slurry suction mold screen frame is convex, and the hot pressing die must be combined with the slurry suction mold, so the hot pressing die must be avoided at the corresponding position, resulting in an empty cavity outside the hot pressing die product. Waste slurry and dirt are easily accumulated in the empty cavity, and because the hot pressing die is on top, the dirt falls onto the convex die. There is no effective way to block and remove the dirt, so the dirt is squeezed into the product when the hot pressing die is combined, resulting in an increase in dark color of the product and a decrease in yield. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a device for cleaning the dirt of a reciprocating hot pressing mold in pulp molding production.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A device for cleaning dirty reciprocating hot pressing molds for pulp molding production, comprising a machine table, support frames are connected to the machine table on both sides of the top by bolts, and the top of the support frame is connected to the top of the top table by bolts, hot pressing punches are arranged on both sides of the top of the machine table, and a hot pressing die is arranged on the top outer wall of the top table, a pulp box is arranged on the top middle outer wall of the machine table, and a pulp suction mold is fixedly connected to the top of the pulp box, and a hot pressing die base is fixedly connected to the top of the hot pressing die.

[0007] Preferably: the bottom outer wall of the hot pressing punch is fixedly connected to a hot pressing punch base, and a hydraulic cylinder is fixedly connected below the hot pressing punch base, and the bottom of the base of the hydraulic cylinder is fixedly connected to a platform base.

[0008] Furthermore: the machine base is fixedly connected to the top outer wall of the machine, and a product is arranged on the top of the hot pressing punch.

[0009] On the basis of the above-mentioned solution: the hot pressing punch is provided with waste edges around the periphery close to the product, and equidistantly distributed air holes are provided around the top of the hot pressing punch.

[0010] A better solution among the above solutions is that an air pipe is provided on the side outer wall of the hot pressing punch, and a valve is fixedly connected to the end of the air pipe.

[0011] As a further solution of the present invention: connecting grooves are arranged around the back side of the hot pressing punch, and the air holes are located in the connecting grooves.

[0012] At the same time, a hot pressing die avoidance plate is arranged near the outer periphery of the waste edge of the hot pressing die.

[0013] As a preferred embodiment of the present invention: a screen pressing frame is arranged around the top of the slurry suction mold.

[0014] The beneficial effects of the present invention are:

[0015] 1. A device for cleaning dirt in a reciprocating hot pressing mold for pulp molding production is convenient. Each air hole is connected to each other through a connecting groove. At the same time, the air pipe is connected to an external air compression system. The size of the valve is adjusted to control the strength of the air flow, which meets the requirements of adapting different products to prevent waste pulp and dirt from adhering to the mold. The air flow is discharged through the air holes in the connecting groove of the hot pressing punch, forming an air curtain around the mold, thereby preventing waste pulp and dirt from falling onto the hot pressing punch. The formation of the air curtain can also keep the product warm and prevent the temperature in the mold from being transferred to the outside world. Seconds before the hot pressing punch and the hot pressing concave mold are opened, the air compression system controls the valve to increase the air flow rate, and uses the air flow to flush and clean the mold. Because the mold is not opened, the product will not be contaminated, reducing the generation of product discoloration. At the same time, the overall device runs synchronously with the machine, does not increase the operating cycle, and cleans automatically.

[0016] 2. This device is convenient for cleaning the dirt of the reciprocating hot pressing mold in pulp molding production. Through the setting of the pressing frame, it can help fix the upper structure of the mold and prevent displacement or deformation during the production process, thereby ensuring the stability and accuracy of the pulp suction mold during work, ensuring the quality of the finished product, and at the same time increasing the stability of the mold structure, reducing the occurrence of accidents, improving the safety of the production site, reducing the vibration of the mold during work, and reducing the degree of wear of the mold.

[0017] 3. The device is convenient for cleaning the dirt of the reciprocating hot pressing mold in pulp molding production. The hot pressing mold avoidance plate is set to prevent the hot pressing mold from colliding with other mold parts during the closing process, thereby ensuring the integrity of the mold. At the same time, the hot pressing mold avoidance plate can be used as a protective layer for the hot pressing mold, reducing the possibility of external impact and wear on the hot pressing mold, extending the service life of the hot pressing mold, improving the stability and efficiency of the production line, and ensuring the quality of the finished product.
