Description

Technical Field

[0001] This utility model relates to the technical field of paper mold forming equipment, specifically a high-efficiency drying paper mold forming equipment. Background Technology

[0002] Pulp molding products are made by adding appropriate chemical additives to pulp of a certain concentration in a molding machine and then using vacuum or pressure to evenly distribute the fibers on the surface of the mold, thereby forming a wet paper mold blank with a predetermined geometric shape and size. The product is then further dehydrated, demolded, dried and shaped. Paper molding equipment is specifically designed for the production of paper mold products.

[0003] Chinese utility model patent CN202421265947.0 discloses a paper mold drying production line. This line incorporates a tray component with ventilation grooves, allowing hot airflow from the drying device to enter the ventilation grooves through ventilation holes and contact the bottom of the paper mold. This increases the contact area between the hot airflow and the bottom of the paper mold, causing the moisture in the wet paper mold blank to evaporate. The moisture is then carried away through the ventilation holes, ensuring the bottom of the paper mold is dried and increasing the drying speed while effectively reducing energy consumption. However, this paper mold drying production line can only be used to dry one type of wet paper mold blank at a time. Changes in the moisture content, thickness, and material of the wet paper mold blank require adjustments to the temperature and conveying speed of the drying production line, which is difficult, time-consuming, and labor-intensive, impacting the production efficiency of the paper mold.

[0027] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0028] The following specific examples illustrate the implementation of this disclosure. Those skilled in the art can easily understand other advantages and effects of this disclosure from the content disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them.

It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0029] Reference Figures 1-3 , Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 This is a schematic diagram of the molded component structure of this utility model; Figure 3 This is a schematic diagram of the drying component structure of this utility model. A high-efficiency drying paper mold forming device includes: a pulp component 1, a forming component 2, and a drying component 3. The pulp component 1 is filled with pulp. The forming component 2 includes a lower mold assembly 21, an upper mold assembly 23, and a conveying assembly 24. The lower mold assembly 21 is disposed on the pulp component 1 and adsorbs the pulp inside the pulp component 1 to form a wet paper mold blank. The upper mold assembly 23 is disposed on one side of the lower mold assembly 21 and adsorbs the wet paper mold blank on the lower mold assembly 21. The conveying assembly 24 is connected to one end of the upper mold assembly 23 and drives the upper mold assembly. The component 23 moves and transports the wet paper mold blank. There are at least two lower mold components 21 and two upper mold components 23, which are arranged side by side. The drying component 3 includes a conveying component 31 and a drying component 32. The conveying component 31 is located on one side of the transport component 24 and receives and transports the wet paper mold blank transported by the upper mold component 23. The conveying speed of each conveying component 31 is independently controlled, and the number of conveying components 31 is the same as the number of lower mold components 21 and upper mold components 23 arranged side by side. The drying component 32 is located on the conveying path of the conveying component 31.

[0030] This high-efficiency drying paper mold forming equipment, by setting up at least two upper mold components 23 and lower mold components 21 arranged side by side, enables the conveying component to drive the upper mold component 23 to transport at least two paper mold wet blanks at one time, and place them on a conveying component 31 for conveying. Under the action of the conveying component 31 conveying the paper mold wet blanks through the drying component 32, the paper mold wet blanks are dried, completing the paper mold forming process. Furthermore, when processing different types of paper molds, the conveying speed of different conveying components 31 can be controlled to make the paper mold wet blanks stay in the drying component 32 for the most appropriate time, thereby improving the production efficiency and adjustment efficiency of paper molds and reducing energy consumption.

[0031] Specifically, the conveying component 31 is a conveying device consisting of a motor, a reducer, a frame, and a conveyor belt. It conveys the wet paper mold blank by placing it on the conveyor belt and having the motor and reducer work together to drive the conveyor belt to rotate in a circular manner. The motor speed can be freely controlled, thereby achieving the effect of controlling the conveyor belt speed.

[0032] Furthermore, by using a drying component 32 to dry the wet paper mold blanks conveyed on at least two conveying components 31, the production cost of the equipment and the energy consumption during the production of paper molds are reduced, thereby increasing production capacity.

[0033] Specifically, the conveying component 31 is a metal mesh conveying device, which allows the wet paper mold blank to be placed on the conveying component 31 for conveying, and the mesh conveyor belt will not affect the drying of the bottom surface of the wet paper mold blank, thereby improving the drying efficiency.

[0034] Reference Figure 4 , Figure 4 This is another structural schematic diagram of the molding component of this utility model. The lower mold assembly 21 includes a vent pipe 211, a lower mold 212, and a connecting pipe 213. The vent pipe 211 is installed on the pulp component 1, the lower mold 212 is installed on the circumferential side of the lower mold 212, and the connecting pipe 213 connects the vent pipe 211 and the connecting pipe 213, and connects the inner cavity of the vent pipe 211 and the surface of the connecting pipe 213. This allows the air pump to be connected to the vent pipe 211, so that when the air pump is connected to the vent pipe 211, the connecting pipe 213 connects the vent pipe 211 and the lower mold 212, causing negative pressure to be generated on the surface of the lower mold 212 or air to be blown outward from the surface of the lower mold 212.

[0035] Specifically, when the lower mold 212 adsorbs the pulp, the air pipe 211 and the connecting pipe 213 are under negative pressure, which generates suction on the surface of the lower mold 212. When the lower mold 212 separates from the wet paper mold blank, the gas is blown down to the lower mold 212 through the air pipe 211 and the connecting pipe 213, causing the wet paper mold blank to separate from the lower mold 212 under the action of gas impact, which facilitates the upper mold assembly 23 to transport the wet paper mold blank.

[0036] The inner cavity of the vent pipe 211 is provided with a partition plate, which is arranged along the axis of symmetry of at least two lower molds 212, dividing the inner cavity of the vent pipe 211 into at least two spaces. This allows the vent pipes 211 in the at least two spaces to independently control the suction and blowing forces of the at least two lower molds 212. They do not affect each other when the pulp is adsorbed and the paper mold wet blank is separated. Furthermore, when the lower mold 212 adsorbs the pulp, the adsorption time of the pulp can be controlled according to product requirements, thereby controlling the thickness of the paper mold wet blank on the surface of the lower mold 212. This achieves the effect of simultaneously producing at least two different paper mold wet blanks.

[0037] The upper mold assembly 23 includes an upper mold drive 231 and an upper mold 232. The upper mold drive 231 is located directly above the vent pipe 211. The drive end of the upper mold drive 231 is connected to the upper mold 232, and the surface of the upper mold 232 is connected to an air pump, which allows the surface of the upper mold 232 to suck in and blow air. The upper mold drive 231 drives the upper mold 232 to move closer to and further away from the lower mold 212, so that the wet paper mold blank can be longitudinally transported through the cooperation of the upper mold drive 231 and the upper mold 232.

[0038] Specifically, the two upper mold components 23 are independently controlled. Each upper mold drive component 231 controls the upper mold 232 to move closer to or further away from the lower mold 212 to pick up and transport the paper mold wet blank. The position of the upper mold 232 can be adjusted according to the needs. For example, if a thinner paper mold is required, the moving distance of the upper mold 232 can be increased, so that when the lower mold 212 and the upper mold 232 are closed, the pressure between them increases, and the paper mold wet blank becomes thinner under pressure. When a thicker paper mold is required, the moving distance of the upper mold 232 can be reduced, so that when the lower mold 212 and the upper mold 232 are closed, the pressure between them decreases, and the paper mold wet blank becomes thicker, thereby achieving the effect of controlling the thickness and density of the paper mold.

[0039] Specifically, when the upper mold 232 is transporting the wet paper mold blank on the surface of the lower mold 212, the surface of the lower mold 212 blows air outward while the surface of the upper mold 232 sucks air in, thereby separating the wet paper mold blank from the lower mold 212 and adsorbing it by the upper mold 232. This allows the upper mold drive 231 to drive the upper mold 232 to move, thus transporting the wet paper mold blank.

[0040] The conveying assembly 24 includes a conveying drive 241, a screw 242, and a mounting plate 243. The mounting plate 243 is connected to multiple upper mold drive components 231, forming an integral unit. When the mounting plate 243 moves, it can drive the multiple upper mold drive components 231 to move synchronously, conveying the paper mold wet blank adsorbed by the upper mold 232. The conveying drive 241 is located on one side of the mounting plate 243. The screw 242 is connected to the drive end of the conveying drive 241. The conveying drive 241 drives the screw 242 to rotate. The screw 242 is connected to the mounting plate 243, so that when the screw 242 rotates forward and backward, it can drive the mounting plate 243 to move laterally, thereby enabling the upper mold 232 to convey the paper mold wet blank.

[0041] The upper mold assembly 23 also includes an upper mold guide 233. One end of the upper mold guide 233 is connected to the upper mold 232, and the other end passes through the mounting plate 243, so that the movement of the upper mold 232 can be guided by the upper mold guide 233, and the stability of the upper mold 232 moving along the driving direction of the upper mold drive 231 can be improved, thereby improving the handling efficiency.

[0042] Furthermore, at least two lower molds 212 are arranged side by side on opposite sides of the circumference of the vent pipe 211, so that for every 180 degrees that the vent pipe 211 rotates, at least two lower molds 212 will be in an upward state, and at least two other lower molds 212 will be in the pulp, adsorbing the pulp. This ensures that the wet pulp blank can be transported once every 180 degrees that the vent pipe 211 rotates, thereby improving production efficiency.

[0043] The transport assembly 24 also includes a guide rail 244, which is connected to the mounting plate 243. The transport drive component 241 drives the screw component 242 to rotate, so that the mounting plate 243 drives the upper mold drive component 231 to move along the guide rail 244. By setting the guide rail 244, the movement path of the mounting plate 243 is fixed, and the movement of the mounting plate 243 is more stable, reducing the pressure required to bear by the screw component 242.

[0044] The forming component 2 also includes a rotating component 22, which is disposed at one end of the lower mold component 21 and drives the lower mold component 21 to rotate. The rotating component 22 is installed at one end of the air pipe 211 and drives the air pipe 211 to rotate around the central axis. This allows the lower mold 212 to rotate into the pulp by driving the air pipe 211 to rotate 180 degrees. The lower mold 212 is then subjected to negative pressure on its surface, which adsorbs the pulp onto the surface of the lower mold 212 to form a wet blank. Then the air pipe 211 is rotated 180 degrees, thereby rotating the lower mold 212, which adsorbs the wet blank, back to its initial position.

[0045] The molding component 2 also includes a limiting component 26, which is disposed at one end of the lower mold component 21 and limits the rotation of the lower mold component 21. The limiting component 26 is disposed on one side of the vent pipe 211 and limits the vent pipe 211. Thus, after the lower mold 212 rotates to the designated position, the limiting component 26 can limit the vent pipe 211, ensuring that the lower mold 212 can be aligned with the upper mold 232, thereby improving the stability of the pressure applied by the upper mold 232 to the wet paper mold blank and the adsorption effect of the wet paper mold blank during transport.
