Description

Technical Field

[0001] This utility model relates to the field of hot pressing equipment technology, and in particular to a hot pressing forming device for electrically heated cloth. Background Technology

[0002] A thermoforming apparatus is a device that uses compressed air as the working medium and employs actuators such as cylinders to convert hydraulic energy back into mechanical energy. This equipment can apply uniform, stable, and precisely controllable pressure to multi-layered structures. It is also equipped with a heating system to provide a suitable temperature environment. Under the combined action of heat and pressure, multi-layered structures can be formed according to predetermined shapes and performance requirements.

[0003] In the production process of electric heating cloth, the collaborative operation between various workstations relies on the conveying of release paper. The release paper carries the lining cloth through each workstation in sequence for layering. To meet processing requirements, the release paper is conveyed intermittently, and multiple layers are hot-pressed into shape at one time using a hot press mold.

[0004] However, traditional hot-pressing molds have fixed positions and cannot accommodate the intermittent feeding of release paper. When the semi-finished electric heating cloth is fed into the forming mold, the release paper must wait for the hot pressing to complete before it can continue feeding, which greatly reduces production efficiency. In addition, the intermittent feeding of the release paper cannot accurately deliver the electric heating cloth into the hot pressing range, which easily leads to inaccurate hot pressing position, affecting the molding quality and increasing the defect rate.

[0032] 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.

[0033] like Figures 1 to 7The hot pressing forming device for electrically heated cloth shown includes: a worktable 1, and a base plate 2, a mounting plate 3 and a hot pressing mold 4 stacked sequentially on the worktable 1;

[0034] The base plate 2 is fixed on the workbench 1, the hot pressing mold 4 is fixed on the mounting plate 3, and a linear drive assembly 5 and a first sliding assembly 6 are provided between the mounting plate 3 and the base plate 2. The first sliding assembly 6 is arranged parallel to the release paper conveying direction, and the linear drive assembly 5 drives the mounting plate 3 to slide on the first sliding assembly 6.

[0035] With the linear drive component 5 and the first sliding component 6, the hot press mold 4 can move synchronously and intermittently along the release paper conveying direction during the intermittent conveying of the release paper, without waiting for the hot pressing time, which improves production efficiency and can meet the needs of large-scale production. In addition, the hot press mold 4 can make precise adjustments to its position according to the release paper conveying rhythm and the arrangement spacing of the layer structure, ensuring that each layer structure can be hot pressed in the correct position, thereby improving the molding quality and reducing the defect rate.

[0036] like Figure 3 As shown, the hot press mold 4 includes a top plate 41, an upper heating plate assembly 42, a lower heating plate assembly 43, and a pressing drive component 44. The top plate 41 is connected to the mounting plate 3 through multiple guide pillars 45. The upper heating plate assembly 42 is slidably connected to the guide pillars 45 through linear bearings 46. The lower heating plate assembly 43 is disposed on the mounting plate 3. Multiple pressing drive components 44 are disposed on the top plate 41, and the driving end of the pressing drive component 44 is connected to the upper heating plate assembly 42.

[0037] During the pressing process, the upper heating plate assembly 42 moves smoothly and linearly along the guide column 45 using the linear bearing 46, which enhances the overall stability of the hot press mold 4. The setting of multiple pressing drive components 44 enables precise control of the pressure applied to the upper heating plate assembly 42, thereby improving the molding quality.

[0038] Preferably, both the upper heating plate assembly 42 and the lower heating plate assembly 43 include a heating layer 42a, a heat insulation layer 42b, and a connecting plate 42c; the heat insulation layer 42b is located between the heating layer 42a and the connecting plate 42c.

[0039] The heat insulation layer 42b effectively reduces heat loss to the connecting plate 42c and the surrounding environment, ensuring that heat energy is concentrated in the heating layer 42a, improving heat utilization efficiency, and enabling the layer structure to reach the required molding temperature in a shorter time, thereby improving production efficiency. The presence of the heat insulation layer 42b can prevent the connecting plate 42c from thermal deformation or damage due to prolonged exposure to high-temperature environments, helping to extend the service life of the connecting plate 42c and reduce mold maintenance and replacement costs.

[0040] During the intermittent conveying of the release paper, slight deviations may occur in the position of the layer structures. Therefore, to ensure the accuracy of the hot pressing position, a second sliding component 7 is provided between the mounting plate 3 and the lower heating plate group 43. The second sliding component 7 is arranged parallel to the release paper conveying direction; and an adjustment component is provided on one side of the mounting plate 3 and the lower heating plate group 43. Through the second sliding component 7 and the adjustment component, the lower heating plate group 43 is finely adjusted to ensure that each layer structure is hot-pressed in the correct position, thereby improving the molding quality.

[0041] In specific implementation, both the first sliding component 6 and the second sliding component 7 are equipped with limiting elements 13 at their respective sliding ends. The limiting elements 13 can be in the form of limiting blocks or limiting switches. Specifically, a limiting block can be fixed to the end of the sliding component, limiting the movement range of the sliding part through physical obstruction. A limiting switch can be installed at the end of the sliding component, controlling the movement range of the sliding part through electrical signals. During equipment operation, when the sliding part approaches the limiting element 13, the limiting element 13 will trigger a corresponding protection mechanism to stop the movement of the sliding part, thereby ensuring the safe operation of the equipment.

[0042] In this design, both the first sliding assembly 6 and the second sliding assembly 7 include a slide rail fixed to the base plate 2 and a set of sliders disposed at the bottom of the mounting plate 3. The sliders are slidably mounted on the guide rail. The cooperation between the slide rail and the sliders effectively reduces wobbling and offset during the sliding process, ensuring that the sliding components move smoothly on the predetermined track, thereby improving the accuracy and quality of hot pressing.

[0043] As a preferred embodiment of the above solution, the adjustment assembly includes an adjustment block 8 disposed on the mounting plate 3 and an adjustment hole 9 disposed on the lower heating plate assembly 43; the adjustment block 8 is provided with a strip groove at the position corresponding to the adjustment hole 9.

[0044] By adjusting the position of the adjusting block 8 in the strip groove, the positional deviation of the layer structure can be corrected, and the position of the lower heating plate group 43 can be further precisely controlled, thereby improving the molding quality.

[0045] In a preferred embodiment of this utility model, a sensing plate 10 is provided on the mounting plate 3, and a position sensor 11 is provided on the base plate 2.

[0046] The position feedback achieved through the sensing element 10 and the position sensor 11 can be connected to a control system (such as a PLC or CNC system) to achieve automated control. The position sensor 11 can be a photoelectric sensor, a magnetic sensor, or a proximity switch. When the mounting plate 3 slides on the slide rail, the sensing element 10 triggers the position sensor 11, which then feeds back the position information to the control system. Based on the feedback information, the control system automatically adjusts the action of the linear drive assembly 5 to ensure that the mounting plate 3 and the lower heating plate assembly 43 are in the correct positions for hot pressing.

[0047] In this utility model, the linear drive assembly 5 includes a drive motor, a transmission screw, a nut, and a bearing housing; bearing housings are provided at both ends of the transmission screw, the bearing housings are fixed on the base plate 2, the nut is slidably disposed on the transmission screw, and the drive motor is connected to one end of the transmission screw through a coupling.

[0048] The drive motor drives the transmission screw to rotate, and the nut slides on the transmission screw, thereby realizing the linear movement of the mounting plate 3. This enables precise linear motion control, ensuring the positional accuracy and movement speed stability of the mounting plate 3 during the sliding process, thus improving the molding quality.

[0049] In a preferred embodiment of this invention, a plurality of support blocks 12 are provided between the base plate 2 and the worktable 1. The support height of the support blocks 12 can be adjusted according to actual needs to ensure that there is sufficient gap between the base plate 2 and the worktable 1 for ventilation and heat dissipation. Preferably, the support blocks 12 can be made of heat-insulating materials (such as ceramic or high-strength plastic). In addition, both the top plate 41 and the mounting plate 3 are provided with through grooves to improve heat dissipation efficiency.

[0050] Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of this utility model as claimed.
