Description

Technical Field

[0001] This utility model belongs to the field of paper tray manufacturing technology, and in particular relates to a rapid cooling paper tray heating and shaping machine. Background Technology

[0002] Paper tray pressing is an advanced three-dimensional papermaking technology that primarily uses waste paper as raw material. Through a molding machine and specially designed molds, it shapes various three-dimensional paper products. This technology not only achieves efficient recycling of waste paper but also produces complex, high-strength, and environmentally friendly paper products, widely used in packaging, pallets, and cushioning materials. Chinese patent application CN202021327303.1 discloses a heated shaping machine for paper tray processing, including a shaping mold. A pressure sensor is installed inside the base plate of the shaping mold, a microcontroller is installed on the other side of the pressure sensor, and a PLC controller is installed on the other side of the microcontroller. A conveyor belt is installed at the bottom of the shaping mold, and a shaping block is installed at the top of the shaping mold. An electric heating ring is fixedly connected inside the shaping block. A telescopic rod is fixedly connected to the end of the shaping block away from the shaping mold. A cylinder is installed at the end of the telescopic rod away from the shaping block. A cylinder base is installed at the end of the cylinder near the telescopic rod, with a threaded hole running through it. A crossbeam is installed at the end of the cylinder base away from the cylinder, and keel frames are installed on both sides of the crossbeam. This invention improves heat utilization by placing the electric heating ring inside the shaping block, thus avoiding most of the heat loss during the transfer process. However, this technology lacks a cooling mechanism, requiring natural cooling after each heating and shaping of the paper tray before it can be removed. This results in low processing efficiency, long processing time, and the inability to continuously heat and shape the paper tray during each cooling process, affecting continuous production efficiency. Utility Model Content

[0003] Based on the above background, the purpose of this utility model is to provide a rapid cooling paper tray heating and shaping machine.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A rapid cooling paper tray heating and shaping machine includes a processing table;

[0006] The processing table is provided with a first support, and second supports are symmetrically provided on both sides of the first support.

[0007] The first support is equipped with a first cylinder, the output end of the first cylinder is connected to a mounting plate, an upper mold is detachably connected to the mounting plate, and a heating block is provided inside the upper mold;

[0008] The processing table is provided with a first groove, and a movable plate is slidably disposed in the first groove. A lower mold is symmetrically disposed on the top of the movable plate, and the lower mold is detachably disposed on the movable plate.

[0009] The movable plate is symmetrically provided with ejector plates, and the bottom of the lower mold is provided with a first slot. The ejector plates are engaged with the first slot and slide up and down relative to the bottom of the lower mold.

[0010] Both of the second brackets are equipped with cooling components.

[0011] The above technical solution involves placing the paper to be processed and shaped into a lower mold. After the upper mold is heated, it engages with the corresponding lower mold to shape the paper tray. Subsequently, the upper mold moves upward, leaving the paper tray in the lower mold. A moving plate moves the lower mold containing the paper tray to below one of the second supports, where a cooling component rapidly cools the paper tray. Simultaneously, the ejector plate moves upward, ejecting the paper tray from the lower mold for easy removal. During this process, another lower mold has moved below the upper mold, allowing for the shaping of the next batch of paper while the paper tray is cooling, thus achieving continuous production and significantly improving work efficiency.

[0012] Furthermore, the cooling component includes a wind box, which is fixedly mounted on a second bracket. The bottom of the wind box is provided with a first air outlet pipe, the lower end of which is tapered.

[0013] Through the above technical solution, the first air outlet duct cools the paper tray in the lower mold that has moved below it.

[0014] Furthermore, the movable plate is provided with ventilation holes, which are L-shaped, with one end of the ventilation hole located below the top plate and the other end penetrating through the side of the movable plate;

[0015] The first groove has connecting holes on its side. The connecting holes are located at both ends of the first groove. When the lower mold moves to the bottom of the corresponding second bracket, the ventilation hole located below the lower mold communicates with the corresponding connecting hole.

[0016] The side of the first air outlet pipe is connected to the second air outlet pipe, and the other end of the second air outlet pipe extends into the processing table and is connected to the connection hole.

[0017] With the above technical solution, when the ejector plate moves upward, the first air outlet duct blows cold air from above the paper tray, directly cooling the surface of the paper tray. Simultaneously, the second air outlet duct connects to the ventilation hole via a connecting hole, allowing cold air to flow out from the ventilation hole and enter the lower mold through the gap between the ejector plate and the bottom of the lower mold, cooling the paper tray from the bottom. This simultaneous cooling design from both above and below significantly accelerates the cooling efficiency of the paper tray, ensuring it reaches the required temperature for shaping in a short time, thereby improving production efficiency and product quality.

[0018] Furthermore, a second groove is provided on the side of the first groove, and a threaded rod is rotatably provided in the second groove. One end of the threaded rod extends out of the second groove and is connected to a motor. The motor is fixedly installed on the side of the processing table.

[0019] The side of the movable plate is provided with a sliding block, which is slidably disposed in the second groove and is threadedly connected to the threaded rod.

[0020] The above technical solution uses a motor to drive the threaded rod to rotate, thereby causing the moving plate to slide within the first groove.

[0021] Furthermore, a placement slot is provided on the movable plate, which is located below the top plate. A second cylinder is fixedly installed in the placement slot, and the output end of the second cylinder is connected to the bottom of the top plate.

[0022] Using the above technical solution, the second cylinder drives the ejector plate to move upward, pushing out the paper tray.

[0023] Furthermore, the lower mold has fixing blocks on both sides, and the fixing blocks are connected to the moving plate by bolts.

[0024] The above technical solution enables the detachable connection of the lower mold.

[0025] Furthermore, a first insert block is fixedly provided on the top of the upper mold, and four first insert blocks are symmetrically arranged on the top of the upper mold. A second slot is opened at the upper end of the first insert block, and the second slot passes through both sides of the first insert block.

[0026] The mounting plate has a first slot; the first slot penetrates the mounting plate; and the first slot is correspondingly inserted into a first plug block.

[0027] The top of the mounting plate is provided with a second insert block, which is U-shaped and whose two ends are inserted into the second slot respectively.

[0028] The mounting plate is provided with positioning frames, and the two positioning frames are inserted into the two ends of the second insert block respectively;

[0029] The positioning frame, the second insert block, and the mounting plate are connected by bolts.

[0030] With the above technical solution, the first insert is inserted into the first slot, and its upper end extends out of the first slot and is located above the mounting plate. The second insert is inserted into the second slot, and both ends of the second insert are inserted into the positioning frame. The positioning frame, the second insert, and the mounting plate are bolted together from the top to complete the installation of the upper mold.

[0031] Furthermore, the top of the mounting plate is symmetrically provided with a first movable groove, and the bottom of the second insert is provided with a first movable block, the first movable block being slidably connected to the first movable groove.

[0032] The above technical solution allows for sliding and limiting of the second insert block, thus better securing the upper mold.

[0033] Furthermore, the first bracket has a second movable groove on its opposite sides, and the mounting plate has a second movable block on both sides, with the second movable block slidably disposed in the second movable groove.

[0034] The above technical solution ensures the stability of the mounting plate's vertical movement, thus better guaranteeing the heating and shaping effect on the paper tray.

[0035] This utility model has the following beneficial effects:

[0036] 1. The paper to be processed and shaped is placed in the lower mold. After the upper mold is heated, it cooperates with the corresponding lower mold to complete the shaping of the paper tray. Then, the upper mold moves upward, leaving the paper tray in the lower mold. By moving the moving plate, the lower mold containing the paper tray is moved under one of the second supports, and the cooling component rapidly cools the paper tray. At the same time, the ejector plate moves upward, ejecting the paper tray from the lower mold for easy removal. During this process, the other lower mold has moved under the upper mold, allowing the next batch of paper to be shaped while the paper tray is cooling, thus achieving continuous production and significantly improving work efficiency.

[0037] 2. As the ejector plate moves upward, the first air outlet duct blows cold air from above the paper tray, directly cooling its surface. Simultaneously, the second air outlet duct connects to the ventilation holes via connecting holes, allowing cold air to flow out and enter the lower mold through the gap between the ejector plate and the bottom of the lower mold, cooling the paper tray from the bottom. This simultaneous top and bottom cooling design significantly accelerates the cooling efficiency of the paper tray, ensuring it reaches the required temperature for shaping within a short time, thereby improving production efficiency and product quality.

Cold air flows out from the ventilation hole 52 and enters the lower mold 4 through the gap between the ejector plate 51 and the bottom of the lower mold 4, cooling the paper tray from the bottom. This design of cooling from both the top and bottom significantly accelerates the cooling efficiency of the paper tray. While cooling, another lower mold 4 moves to the bottom of the upper mold 3, which can simultaneously perform shaping processing on the paper, realizing continuous production of paper tray shaping.
