Description

Technical Field

[0001] This application relates to the field of thermoforming technology, and in particular to an energy-saving heating mechanism for thermoforming. Background Technology

[0002] Thermoforming is a specialized plastic processing method that shapes thermoplastic sheets into various products. The sheet is clamped in a frame and heated to a softened state. Under external force, it is forced to conform to the mold surface to achieve a shape similar to the mold surface. After cooling and setting, it is trimmed to obtain the finished product. This process is also used in rubber processing. In recent years, thermoforming has made new advancements, such as continuous production technology from extruded sheets to thermoforming.

[0003] The heating process of the sheet material is the most crucial part of the entire processing. Because existing heating mechanisms can only heat a single, fixed area, extending the heating time is necessary to ensure that materials further from the heat source are also adequately heated, resulting in a double waste of production energy and time.

[0004] In view of this, there is an urgent need for an energy-saving heating mechanism for thermoforming to solve the above problems. Summary of the Invention

[0005] To help solve the problems existing in the prior art, this application provides an energy-saving heating mechanism for thermoforming, which adopts the following technical solution: it includes two heating components arranged in parallel from top to bottom, each heating component including a heat source panel, a slide rail and a drive component;

[0006] The heat source panel is slidably mounted on the slide rail, and the driving component is used to drive the heat source panel to slide on the slide rail.

[0007] A further feature is that,

[0008] The heat source panel is provided with support plates on both sides, and there are two slide rails. The two support plates are slidably mounted on the two slide rails respectively.

[0009] The bottom of the support plate is provided with multiple slots, which are engaged with the corresponding slide rails.

[0010] The drive assembly includes two gears and a synchronizing element for driving the two gears to rotate synchronously. Each of the two slide rails is provided with a rack. The two gears are rotatably mounted on two support plates, and the two gears mesh with the two racks respectively.

[0011] The synchronizing element includes a synchronizing shaft and a power motor. The two ends of the synchronizing shaft are coaxially connected to two gears, and the power motor is used to drive the synchronizing shaft to rotate.

[0012] The support plate is provided with a mounting bracket, and the gear is rotatably mounted on the mounting bracket.

[0013] The heat source panel consists of multiple heating plates, which are positioned on the same horizontal plane.

[0014] Multiple fixing plates are provided on both support plates, and each fixing plate is vertically provided with an adjusting screw. The adjusting screw is threadedly connected to the fixing plate, and the bottom of the adjusting screw is rotatably connected to the heat source panel.

[0015] It also includes a drive assembly for driving the rotation of multiple adjusting screws.

[0016] A mounting plate is provided on one side of the support plate, and a roller is rotatably provided on the suspended end of the mounting plate.

[0017] In summary, when in use, the slide rail is installed on the thermoforming equipment. When the sheet material needs to be heated, the drive component drives the heat source panel to slide on the slide rail. After heating one area, the drive component drives the heat source panel to continue sliding to heat the unheated areas. This allows the material in areas far from the heat source panel to be fully heated quickly, saving production energy and time and improving processing efficiency. Attached Figure Description

[0022] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0023] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification, claims and accompanying drawings of this application are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product or device.

[0024] The following is in conjunction with the appendix Figure 1-3 This application provides further details.

[0025] Reference Figure 1-2 An energy-saving heating mechanism for thermoforming includes two parallel heating components arranged from top to bottom. Each heating component includes a heat source panel 1 (composed of multiple heating plates), a slide rail 2, and a drive component. The heat source panel 1 is slidably mounted on the slide rail 2. The drive component drives the heat source panel 1 to slide on the slide rail 2. In use, the slide rail is installed on the thermoforming equipment (the sheet material heating area is within the slide rail travel). When the sheet material needs to be heated, the drive component drives the heat source panel 1 to slide on the slide rail. After heating one area, the drive component drives the heat source panel 1 to continue sliding to heat the unheated area. This quickly ensures that the material in areas far from the heat source panel is fully heated, saving production energy and time, and improving processing efficiency.

[0026] Reference Figure 1-2 To make the heat source panel 1 slide more smoothly, support plates 3 are provided on both sides of the heat source panel 1. There are two slide rails 2. The two support plates 3 are slidably mounted on the two slide rails 2 respectively, supporting the heat source panel 1 from both sides at the same time, making the heat source panel 1 more stable when sliding. The bottom of the support plate 3 is provided with multiple slots 4, which are engaged with the corresponding slide rails 2 to limit and guide the movement of the support plate 3.

[0027] Reference Figure 1-3 The drive assembly includes two gears 5 and a synchronizing element for driving the two gears 5 to rotate synchronously. Each of the two slide rails 2 is equipped with a rack 6. The two gears 5 are rotatably mounted on two support plates 3, and each gear 5 meshes with a rack 6. Thus, the synchronizing element drives the two gears 5 to rotate synchronously, causing them to roll on the racks 6 on the slide rails 2. This, in turn, causes the two support plates 3 to slide on the slide rails 2, achieving the purpose of moving the heat source panel 1. The synchronizing element includes a synchronizing shaft 7 and a power motor 8. Both ends of the synchronizing shaft 7 are coaxially connected to the two gears 5. The power motor 8 drives the synchronizing shaft 7 to rotate, causing the two gears 5 to rotate synchronously, ensuring consistent movement on both sides of the heat source panel 1.

[0028] Reference Figure 2-3The specific installation structure of gear 5 is as follows: a mounting bracket 10 is provided on the support plate 3, and gear 5 is rotatably mounted on the mounting bracket 10, so as to stably support the rotation of gear 5.

[0029] Reference Figure 1 The heat source panel 1 is composed of multiple heating plates. The multiple heating plates are on the same horizontal plane, which can ensure that the heating efficiency of different positions of the heat source panel 1 is consistent and the heat is even. In order to support the multiple heating plates more stably, two carrier plates 11 are provided between the two support plates 3. The two ends of the multiple heating plates are respectively set on the top of the two carrier plates 11. In order to quickly assemble and disassemble the heating plates, the heating plates are fixed to the carrier plates 11 with bolts.

[0030] Reference Figure 1-2 Since the optimal heating height varies for raw materials of different thicknesses and materials, using the same heating height would lead to unstable production processes. To adapt to the processing of different types of products, multiple fixed plates 11 are provided on both support plates 3. Each fixed plate 11 is vertically equipped with an adjusting screw 12, which is threadedly connected to the fixed plate 11. The bottom of the adjusting screw 12 is rotatably connected to the heat source panel 1. Thus, by turning the adjusting screw 12 on each fixed plate 11, the height of the heat source panel 1 can be adjusted to meet the processing requirements of different products. The rotation of the adjusting screw 12 can be driven manually or by setting up a drive assembly to drive multiple adjusting screws 12 to rotate. The drive assembly can consist of multiple drive motors, with each adjusting screw 12 equipped with a drive motor. The drive motors drive the adjusting screw 12 to rotate, improving the convenience of adjustment.

[0031] To further optimize the process and make the sliding of the heat source panel 1 smoother, a mounting plate is provided on one side of the support plate 3, and a roller 9 is rotatably mounted on the suspended end of the mounting plate. In this way, a sliding track can be set on the thermoforming equipment, so that the roller 9 can be locked on the sliding track, thereby limiting and guiding the sliding of the heat source panel 1 again.

[0032] In summary: When in use, the slide rail is installed on the thermoforming equipment. When the sheet material needs to be heated, the drive component drives the heat source panel 1 to slide on the slide rail. After heating one area, the drive component drives the heat source panel 1 to continue sliding, so that the unheated area can be heated. This allows the material in areas far from the heat source panel to be fully heated quickly, saving production energy and time and improving processing efficiency.

[0033] Improved heating uniformity: Due to the large heating area, the heat source panel 1 consists of multiple heating plates, thus having multiple heating sources. The heat source panel 1 can be driven by a motor 8 to move horizontally back and forth, effectively solving the problem of inconsistent temperatures between the heating source intervals and the area directly below, resulting in more uniform heating of the raw materials. The heating sources are controlled to move horizontally back and forth at a speed of 5 cm per second, and the heating height is adjusted according to the thickness of the raw materials. Experimental results show that the heating uniformity of the raw materials is significantly improved, heating time is shortened by 30%–45%, and power consumption is reduced by 20%–30%.

[0034] Improved heating efficiency: By appropriately adjusting the height of the heat source panel 1, the heating uniformity is significantly improved, ensuring that the raw materials are heated properly without extending the heating time, thus significantly improving production efficiency.

[0035] Enhanced applicability: The height of the heat source panel 1 can be flexibly adjusted according to raw materials of different thicknesses and materials, improving the stability and applicability of the production process.

[0036] Energy saving: Shortening heating time reduces electricity consumption and avoids material waste caused by localized overheating, thus reducing production costs.

[0037] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
