Description

Technical Field

[0001] This utility model relates to the field of pressing machines, and in particular to a high-temperature vacuum pressing machine for TP materials. Background Technology

[0002] With the continuous development of society and the economy, more and more mechanical equipment is being manufactured and widely used in agriculture, industry, and service industries. Mechanical equipment comes in a wide variety of types, and has undergone further innovation to meet different needs, playing an indispensable role in people's work and life; mechanical equipment is ubiquitous.

[0003] The internal structure of mechanical equipment is becoming increasingly complex, and its functions are becoming more and more diverse, and it is constantly being improved. Mechanical equipment generally includes drive devices, speed change devices, transmission devices, working devices, braking devices, protective devices, lubrication systems, cooling systems, etc., and different devices play different roles in mechanical equipment.

[0004] TP material is thermoplastic material. Common TP materials include TPE (thermoplastic elastomer) and TPU (thermoplastic polyurethane). Generally, a single sheet of TP material has a standard thickness. However, the thickness required to manufacture other products using TP material varies. Therefore, multiple sheets of TP material need to be laminated and pressed together to form a TP sheet of the required thickness before product manufacturing can proceed.

[0005] Currently, the lamination process for TP materials typically involves pressing multiple sheets of TP material together using heated rollers to form a single TP sheet. However, this heated roller pressing method is prone to problems due to uneven pressure distribution or large gap deviations between the rollers. This can easily lead to misalignment of the TP material relative to the rollers, resulting in an uneven and rough surface on the laminated TP sheet. Consequently, the quality of the produced TP sheets is poor, the defect rate is high, product quality cannot be guaranteed, production is inconvenient, production costs are high, and the product is not competitive, failing to meet current demands. Therefore, it is necessary to research a new technical solution to improve upon these issues. Utility Model Content

[0006] In view of this, the present invention addresses the deficiencies of the existing technology by providing a high-temperature vacuum pressing machine for TP materials. This machine effectively solves the problems in the existing heated roller pressing process for TP materials, where uneven roller pressure distribution or large roller gap deviations easily cause the TP material to shift relative to the pressing rollers. This results in uneven and rough surfaces on the pressed TP sheets, leading to poor quality, high defect rates, and compromised product quality. Consequently, production is inconvenient, costs are high, and the products are not competitive.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0056] The working process of this embodiment is described in detail below:

[0057] First, the carrier 30 is placed on multiple second conveyor rollers 6231 of the lifting platform 623 near the aluminum plate 42. Multiple sheets of TP material are stacked in different directions and placed in the receiving cavity 31 of the carrier 30 (stacked in different directions can make the TP sheets stronger after pressing). The machine is started, and the multiple second conveyor rollers 6231 rotate in the forward direction (along the material conveying direction). The four-clamping mechanism 23 of the carrier conveying device 20 clamps the carrier 30 and conveys the carrier 30 into the heating cavity 401 of the heating device 40. Aluminum plate 42 and infrared heating plate 43 heat multiple TP materials on both sides for 80 seconds to soften them. Next, carrier conveyor 20 transports carrier 30 onto vacuum tray 52 of vacuum pressing device 50. Then, the first up-and-down drive mechanism 53 of vacuum pressing device 50 drives vacuum suction plate 54 downwards. Vacuum suction plate 54 and vacuum tray 52 work together to create a vacuum, using the generated negative pressure to tightly press multiple TP materials together, thus obtaining a pressed TP sheet. Vacuum pressing ensures that the formed TP sheet... The TP sheet has a higher flatness, and the cooling mechanism is used to quickly cool and shape the TP sheet after compression molding, saving more time. Next, the carrier conveyor 20 transports the carrier 30 to multiple second conveyor rollers 6231 of the lifting platform 623 near the vacuum tray 52, completing the operation of compressing multiple TP materials into a TP sheet. At this time, the compressed TP sheet can be removed from the carrier 30. Then, the third up-down drive mechanism 622 of the two lifting mechanisms 62 drives the lifting platform 623 to move downward, so that the lifting platform 623... Multiple second conveyor rollers 6231 and multiple first conveyor rollers 61 are on the same horizontal plane. Multiple second conveyor rollers 6231 and multiple first conveyor rollers 61 rotate in opposite directions (in the opposite direction of material conveying). Multiple second conveyor rollers 6231 and multiple first conveyor rollers 61 convey the empty carrier 30 to the multiple second conveyor rollers 6231 of the lifting platform 623 near the aluminum plate 42. The third up-down drive mechanism 622 drives the lifting platform 623 to move upward, thereby returning the empty carrier 30 to its original position and starting the next round of operation.

[0058] The key design feature of this utility model is:

[0059] By mounting the carrier on a carrier conveyor and having it move laterally, and by placing the heating and vacuum pressing devices on a frame arranged sequentially along the material conveying direction, and mounting the carrier return device on the frame below the carrier conveyor, with its input and output connected to the carrier conveyor respectively, and all components electrically connected to a control box, this high-temperature vacuum press can heat and soften multiple sheets of TP material before vacuum pressing. The vacuum pressing method provides more uniform and stable pressure, resulting in a smoother pressing process. The resulting TP sheets have higher flatness, avoiding unevenness and roughness, effectively improving the quality of TP sheets, greatly reducing the defect rate, ensuring the quality of TP sheets, reducing production costs, and making the product more competitive. Secondly, the aluminum plate and infrared heating plate in the heating device can heat multiple TP materials on both sides, fully softening them, which is beneficial for subsequent vacuum pressing operations. Furthermore, the cooling mechanism can quickly cool and solidify the pressed sheets, saving time and improving product quality. The carrier return device can transport the carrier to its original position and perform continuous circulation operations, eliminating the need for manual carrier handling, reducing manual operation, bringing convenience to production, and meeting current needs.
