Description

Technical Field

[0001] This utility model relates to the field of acrylic sheet forming and processing technology, and in particular to a high-efficiency acrylic sheet forming and processing device with zoned temperature control. Background Technology

[0002] The molding and processing of acrylic sheets generally requires first heating and melting the acrylic raw material using heating equipment, and then placing it into a processing mold for compression molding.

[0003] Traditional acrylic sheet molding and processing equipment typically consists of a separate mold and a separate heating chamber. The acrylic raw material must first be heated in the heating chamber, and then removed and placed into the mold for compression molding, resulting in low molding efficiency. Furthermore, since the heating chamber and mold are separate, the process of removing the heated material and placing it back into the mold may cause a temperature drop due to exposure to the external environment, leading to hardening of the acrylic material and affecting the quality of the hot pressing molding. Summary of the Invention

[0004] The purpose of this invention is to overcome the defects of the existing technology and provide a high-efficiency acrylic sheet forming and processing device with zoned temperature control.

[0005] The objective of this utility model can be achieved through the following technical solutions: A high-efficiency acrylic sheet forming and processing device with zoned temperature control includes a worktable; a circular conveyor belt is mounted on the worktable; a heating box, a heat preservation box, and a compression support are sequentially mounted on the worktable; the heating box, heat preservation box, and compression support are all mounted on both sides of the conveyor belt, with the heating box and heat preservation box set at 90 degrees, and the heat preservation box and compression support set at 90 degrees; four identical lower molds are mounted on the conveyor belt, evenly distributed on the conveyor belt, and symmetrically arranged in pairs at 90 degrees; a compression cylinder is mounted on the top of the compression support; a pressure plate is connected to the telescopic end of the compression cylinder; an upper mold corresponding to the lower mold is mounted on the bottom of the pressure plate; a controller is also mounted on the worktable; the controller is electrically connected to both the conveyor belt and the compression cylinder; the controller is equipped with a conveyor belt start button and a compression cylinder start button.

[0006] Furthermore, a heating partition is provided at the top of the heating chamber; an electric heating wire is provided between the heating partition and the heating chamber; a power adjustment knob is provided on the heating chamber; the electric heating wire is connected to the power adjustment knob; and the power adjustment knob is connected to an external power source.

[0007] Furthermore, the heating partition is provided with heat conduction holes for conducting heat to the bottom of the heating box.

[0008] Furthermore, baffles are respectively hinged at both ends of the heating box by torsion springs, and the torsion direction of the two baffles is towards the direction of the conveyor belt.

[0009] Furthermore, the baffle is positioned so that it adheres precisely to the surface of the conveyor belt when it comes down.

[0010] Furthermore, the insulated box has the same structure as the heating box.

[0011] Compared with the prior art, the present invention has the following advantages: This invention utilizes a circular conveyor belt and a distributed heating box, insulation box, and molding structure, along with four lower molds. The lower molds are driven by the conveyor belt to alternately pass through the heating box, insulation box, and molding structure. After being heated and insulated, they are then driven by a compression cylinder to perform hot pressing molding. This eliminates the need for prolonged exposure to the external environment while waiting for the previous process to finish, thus preventing cooling and hardening. This ensures the quality of the molding process, and the alternating structure allows for process cycles, improving production efficiency. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0015] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention. Example

[0016] like Figures 1-3 As shown, a high-efficiency acrylic sheet forming and processing device with zoned temperature control is disclosed. The device includes a worktable 1; a circular conveyor belt 2 is mounted on the worktable 1, and the conveyor belt 2 has a built-in motor to drive its rotation; the worktable 1 is also sequentially equipped with a heating box 3, a heat preservation box 4, and a compression support 5; the heating box 3, the heat preservation box 4, and the compression support 5 are all mounted on both sides of the conveyor belt 2, with the heating box 3 and the heat preservation box 4 and the compression support 5 arranged at 90 degrees; four identical lower molds 6 are mounted on the conveyor belt 2, evenly distributed on the conveyor belt 2, and symmetrically arranged at 90 degrees in pairs. Each rotation of the conveyor belt 2 rotates 90 degrees, so that the four lower molds 6 always maintain one in the heating box 3 for heating and softening the acrylic material, one in the heat preservation box 4 for temperature maintenance, one under the compression support 5 for hot pressing and forming, and the last one... A separate external compression support 5 is used to retrieve compressed acrylic sheets and place acrylic raw materials back in; a compression cylinder 7 is installed on the top of the compression support 5; a pressure plate 8 is connected to the telescopic end of the compression cylinder 7; an upper mold 9 corresponding to the lower mold 6 is installed at the bottom of the pressure plate 8, used to press down onto the lower mold 6 located directly below for hot pressing of the acrylic sheet; a controller 10 is also installed on the workbench 1; the controller 10 is electrically connected to the conveyor belt 2 and the compression cylinder 7 respectively; the controller 10 is equipped with a conveyor belt start button 11 and a compression cylinder start button 12. Each time the conveyor belt start button 11 is pressed, the conveyor belt 2 rotates 90 degrees, performing a process replacement cycle to ensure continuous and uninterrupted process, thereby improving work efficiency; and each time the compression cylinder start button 12 is pressed, the compression cylinder 7 drives the upper mold 9 to press down once, completing the hot pressing of the acrylic sheet, and then resetting.

[0017] A heating partition 13 is provided at the top of the heating chamber 3; an electric heating wire 14 is provided between the heating partition 13 and the heating chamber 3; a power adjustment knob 15 is provided on the heating chamber 3; the electric heating wire 14 is connected to the power adjustment knob 15; the power adjustment knob 15 is connected to an external power source, and the current through the electric heating wire 14 is adjusted by adjusting the power adjustment knob 15, thereby adjusting the heating temperature of the electric heating wire 14 to complete the heating and softening of the acrylic material; the heating partition 13 is provided with heat conduction holes 1 for conducting heat to the bottom of the heating chamber 3. 6. Improved heat conduction: The heating box 3 has baffles 18 hinged at both ends by torsion springs 17. The torsional direction of the two baffles 18 is towards the direction of the conveyor belt 2. When the lower mold 6 enters or exits the heating box 3, driven by the conveyor belt 2, the lower mold 6 will collide with the baffles 18. The baffles 18 will be lifted by overcoming the elastic force of the torsion springs 17. After the lower mold 6 passes smoothly, the baffles 18 will be reset under the restoring force of the torsion springs 17, forming a seal on the heating box 3 and ensuring stable internal temperature. The baffles 18 are in contact with the surface of the conveyor belt 2 when they are blocked.

[0018] The heat preservation box 4 has the same structure as the heating box 3. The only difference between the two is the power that can be adjusted by the power adjustment knob 15. The temperature controlled by the heat preservation box 4 is lower than that of the heating box 3. The heating box 3 is used for heating and softening, while the heat preservation box 4 is used for heat preservation to prevent hardening again at low temperatures.

[0019] This invention requires only one operator to stand at the lower mold 6 position on the conveyor belt 2, where the controller 10 is also located. First, the acrylic raw material is placed into the lower mold 6. Then, the conveyor belt start button 11 is pressed, and the conveyor belt 2 rotates 90 degrees. At this time, the lower mold 6 rotates into the heating box 3 for heating and softening. After the lower mold 6 has been heated and softened in the heating box 3, it rotates into the insulation box 4 for temperature maintenance. The lower mold 6 in the insulation box 4 will then rotate to the compression bracket 5. At this time, the operator presses the compression cylinder start button 12, and the compression cylinder 7 will drive the upper mold 9 to press down once, completing the hot pressing of the acrylic sheet. Then, it resets, and the lower mold 6 containing the acrylic sheet that was hot-pressed last time has rotated to the operator's position. The acrylic sheet is removed, and acrylic raw material is placed in again, and this cycle is repeated.
