Description

Technical Field

[0001] This utility model belongs to the field of tableware processing technology, and in particular relates to a small pulp molding tableware processing equipment. Background Technology

[0002] In the processing of small-scale pulp molded tableware, the pulp needs to be cooled and shaped inside the mold. However, excessively high mold temperature will prolong the pulp curing time and cause the edges of the tableware to deform. Traditional processing equipment mostly uses natural cooling or independent fan heat dissipation. The former is inefficient, while the latter requires an additional heat dissipation system. Furthermore, the heat dissipation is uneven between the top and bottom of the mold. There is an urgent need for an integrated device that combines heat dissipation and mold driving functions to improve the production efficiency and quality of small-scale pulp molded tableware.

[0003] The following issues exist in the existing technology and require improvement:

[0004] (1) Traditional equipment relies on natural cooling of the mold, which results in a long pulp setting time and low daily output. Although some equipment is equipped with cooling fans, the airflow of the fans can only cover part of the mold surface, resulting in uneven cooling and deviations in the thickness of the tableware, leading to a high scrap rate.

[0005] (2) The existing equipment’s mold drive and heat dissipation system operate independently, requiring a separate power source, resulting in high overall energy consumption and complex equipment structure, increasing maintenance frequency. Utility Model Content

[0006] To address the above issues and overcome the shortcomings of existing technologies, this utility model provides a small-scale pulp molding tableware processing equipment. Through bidirectional operation of an air pump, it integrates mold driving and heat dissipation functions. During forward operation, the airflow difference between the connecting pipe and the exhaust port drives a multi-stage pneumatic telescopic rod to close the mold. Simultaneously, the airflow passes through the heat dissipation box, carrying away heat from the lower mold, while the exhaust port blows away heat from the upper mold, accelerating heat dissipation. During reverse operation, it drives the mold to open, improving mold temperature uniformity and reducing tableware thickness deviation through coordinated heat dissipation from both the upper and lower molds. Furthermore, it eliminates the need for independent heat dissipation components, reducing overall energy consumption and simplifying the structure, thus solving the problems of high energy consumption and low molding accuracy associated with traditional equipment.

[0007] The technical solution adopted by this utility model is as follows: A small pulp molding tableware processing equipment includes a base, a mounting frame set on the upper wall of the base, a multi-stage pneumatic telescopic rod fixedly connected to the mounting frame, an upper mold fixedly set on the output end of the multi-stage pneumatic telescopic rod, and a lower mold fixedly set on the upper wall of the base. The multi-stage pneumatic telescopic rod achieves extension and contraction through the internal airflow difference, driving the upper mold to move up and down to complete the opening and closing action of the mold. The upper mold and the lower mold are vertically corresponding. An airflow heat dissipation box is sleeved on the outside of the lower mold. The airflow heat dissipation box is connected to the multi-stage pneumatic telescopic rod through a pipe. The side of the airflow heat dissipation box near the lower mold has no sidewall. The airflow driven by the air pump circulates in the airflow heat dissipation box, and the heat of the lower mold is carried away by forced convection, thereby achieving efficient heat dissipation of the lower mold.

[0008] As a preferred technical solution of this invention, the output end of the multi-stage pneumatic telescopic rod is connected to the inner bottom wall of the upper mold, and an exhaust hole is provided through the side wall of the output end of the multi-stage pneumatic telescopic rod. The exhaust hole corresponds to the inner side wall of the upper mold, and the gas is discharged from the exhaust hole to blow the inner side wall of the upper mold, accelerate the air circulation in the upper mold, and achieve rapid heat dissipation.

[0009] As a preferred technical solution of this invention, an air pump is fixedly installed on the inner wall of one side of the mounting frame. The air outlet of the air pump is connected to the inside of the airflow cooling box. The air pump is the power core of the equipment and provides gas power through bidirectional operation. When operating in reverse, it drives the multi-stage pneumatic telescopic rod to retract, and when operating in the forward direction, it drives it to extend. At the same time, it provides circulating airflow for mold cooling, realizing the integration of the opening and closing and heat dissipation functions of the upper and lower molds.

[0010] As a preferred technical solution of this invention, an air inlet is provided through one side wall of the mounting bracket, and the air inlet end of the air pump is connected to the air inlet.

[0011] As a preferred technical solution of this invention, a connecting pipe is fixedly installed through the side wall and top wall of the mounting frame, and the two ends of the connecting pipe are respectively connected to the base end of the airflow heat dissipation box and the multi-stage pneumatic telescopic rod.

[0012] As a preferred technical solution of this invention, the air flow rate per unit time at the connection between the connecting pipe and the multi-stage pneumatic telescopic rod is greater than the air flow rate per unit time at the exhaust port.

[0013] The beneficial effects of this utility model after adopting the above structure are as follows:

[0014] (1) The airflow cooling box is wrapped around the outside of the lower mold. The air pump drives the airflow to continuously flow through the mold surface and remove heat through the airflow. The exhaust hole blows the inner wall of the upper mold, accelerates the internal air flow and reduces the temperature difference between the upper mold and the lower mold. The uniformity of the temperature distribution on the mold surface is improved and the thickness deviation of the tableware is reduced. This overcomes the problem of low molding accuracy caused by uneven cooling in traditional heat dissipation methods and meets the dimensional tolerance requirements of the tableware.

[0015] (2) By utilizing the airflow difference between the connecting pipe and the exhaust port, the multi-stage pneumatic telescopic rod is contracted or extended, driving the mold to open and close; at the same time, when the air pump is running in the forward direction, the airflow flows through the multi-stage pneumatic telescopic rod, connecting pipe and airflow heat dissipation box, carrying away the heat of the lower mold, and the exhaust port blows the inner wall of the upper mold, forming a coordinated heat dissipation between the upper and lower parts.

[0016] (3) The air pump operates in both directions (driving the mold to close in the forward direction and driving the mold to open in the reverse direction), simultaneously serving as the power source for the pneumatic telescopic rod and the driving source for the cooling airflow. This avoids the additional energy consumption of an independent cooling system and reduces components such as cylinders and cooling fans, thereby reducing the overall energy consumption of the equipment, simplifying the structure, reducing maintenance costs, and solving the problems of high energy consumption and complex structure of existing equipment.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1-4 As shown, a small pulp molding tableware processing equipment includes a base 1, a mounting frame 2 disposed on the upper wall of the base 1, a multi-stage pneumatic telescopic rod 9 fixedly connected to the mounting frame 2, an upper mold 3 fixedly disposed on the output end of the multi-stage pneumatic telescopic rod 9, and a lower mold 5 fixedly disposed on the upper wall of the base 1. The upper mold 3 and the lower mold 5 are vertically corresponding. An airflow heat dissipation box 6 is sleeved on the outside of the lower mold 5. The airflow heat dissipation box 6 is pipe-connected to the multi-stage pneumatic telescopic rod 9. The side of the airflow heat dissipation box 6 closest to the lower mold 5 has no sidewall.

[0025] The output end of the multi-stage pneumatic telescopic rod 9 is connected to the inner bottom wall of the upper mold 3. The side wall of the output end of the multi-stage pneumatic telescopic rod 9 is provided with an exhaust hole 10, which corresponds to the inner side wall of the upper mold 3.

[0026] An air pump 7 is fixedly installed on one side of the inner wall of the mounting bracket 2, and the air outlet of the air pump 7 is connected to the inside of the airflow heat dissipation box 6.

[0027] An air inlet 8 is provided through one side wall of the mounting bracket 2, and the air inlet end of the air pump 7 is connected to the air inlet 8.

[0028] The bottom wall of the lower mold 5 is provided with a grouting hole 11, which penetrates the base 1.

[0029] The mounting bracket 2 has a connecting pipe 4 fixedly installed inside its side wall and top wall. The two ends of the connecting pipe 4 are respectively connected to the airflow cooling box 6 and the base end of the multi-stage pneumatic telescopic rod 9.

[0030] The air flow rate per unit time at the connection point between the connecting pipe 4 and the multi-stage pneumatic telescopic rod 9 is greater than the air flow rate per unit time at the exhaust port 10.

[0031] In actual use, the air pump 7 is first started in reverse. The outside air enters the multi-stage pneumatic telescopic rod 9 through the exhaust port 10, and then is transported to the airflow cooling box 6 through the connecting pipe 4. Finally, it is discharged from the air inlet 8. During this process, because the air flow rate per unit time at the connection between the connecting pipe 4 and the multi-stage pneumatic telescopic rod 9 is greater than the air flow rate per unit time at the exhaust port 10, the multi-stage pneumatic telescopic rod 9 contracts due to the internal air pressure imbalance, which in turn drives the upper mold 3 to move upward.

[0032] Subsequently, pulp raw materials are injected into the lower mold 5 through the injection hole 11. After the injection is completed, the air pump 7 is started in the forward direction. At this time, external gas is drawn in through the air inlet 8, pressurized by the air pump 7, and discharged through the exhaust hole 10, which pushes the multi-stage pneumatic telescopic rod 9 to extend, causing the upper mold 3 to move downward, so as to achieve precise fitting between the upper mold 3 and the lower mold 5.

[0033] Throughout the entire processing, the airflow in the airflow cooling box 6 continuously circulates, effectively carrying away the heat from the lower mold 5. At the same time, the airflow ejected from the exhaust port 10 blows the inner wall of the upper mold 3, accelerating the airflow speed inside the upper mold 3. Through coordinated heat dissipation from both the upper and lower molds, efficient heat dissipation is achieved for both the upper mold 3 and the lower mold 5, accelerating the cooling and solidification of the pulp, thereby improving the cooling and shaping efficiency.

[0034] If any person skilled in the art, inspired by this invention, designs a similar structure or embodiment without departing from the spirit of this invention, such design should fall within the protection scope of this invention.
