Description

Technical Field

[0001] This utility model relates to the field of hot press technology, specifically a hot press for seat cushion fabric. Background Technology

[0002] A seat cushion fabric hot press machine is a device used for hot pressing seat cushion fabrics. The hot pressing process can change the shape and structure of the fabric surface, giving it better water resistance, stain resistance, and wrinkle resistance. These improved properties can extend the lifespan of the seat cushion and enhance user comfort. Through hot pressing, specific textures or patterns can be formed on the fabric surface to meet design requirements. This not only enhances the aesthetics of the seat cushion but also increases its added value.

[0003] A Chinese patent (CN204471860U) discloses a hot embossing machine for automotive fabrics, including a base and a frame. A pressing system is mounted on the frame, and a heating system is located between the pressing system and the base. An embossing mold is mounted on the heating system. The pressing system includes a hydraulic lifting device, guide pillars and sleeves, and pressure plates. The pressure plates include an upper pressure plate and a lower pressure plate. The upper surface of the upper pressure plate is fixedly connected to the lower end of the guide pillar and the lower end of the push rod of the hydraulic lifting device. The lower surface of the lower pressure plate is fixedly connected to a heat insulation layer. The lower pressure plate is suspended directly below the upper pressure plate by at least three bolts evenly distributed around the push rod. The outermost bolts form a central adjustment area on the upper pressure plate. Several adjusting bolts threadedly connected to the upper pressure plate are located outside the central adjustment area, passing through the upper pressure plate and abutting against the upper surface of the lower pressure plate. This invention eliminates the phenomenon of darker centers and lighter edges in the patterns on automotive fabrics caused by the upward curling of the embossing mold away from the push rod.

[0004] The existing fabric hot press machine described above uses a direct hydraulic lifting and pressing mechanism between the upper and lower pressure plates. In actual use, this design has significant limitations: the opening and closing distance between the upper and lower pressure plates is restricted by the direct hydraulic structure, resulting in extremely limited operating space. As a result, the loading and unloading of fabrics is greatly inconvenient, which not only affects production efficiency but may also increase operational risks. Utility Model Content

[0005] The purpose of this invention is to provide a hot press machine for seat cushion fabric to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a seat cushion fabric hot press machine, comprising: a base plate, a lower pressure plate, and an upper hot press plate. The base plate has slide rails on both sides of its top, a lower pressure plate on top of the slide rails, and gate-shaped supports on both sides of the middle of the base plate. Hydraulic lifting cylinders are located on both sides of the top of the gate-shaped supports. A top plate is located at the bottom of the piston rod of the hydraulic lifting cylinder, and an elastic rubber pad is located at the bottom of the top plate. An upper hot press plate is located at the bottom of the elastic rubber pad, and the length of the lower pressure plate is greater than the length of the upper hot press plate.

[0007] Furthermore, the slide rail is provided with a support roller, the top of which is fixedly connected to the lower pressure plate. A rack is provided on one side of the bottom of the lower pressure plate, and a servo motor is provided on one side of the top of the base plate. A gear is provided at the top of the output shaft of the servo motor, and the gear cooperates with the rack.

[0008] Furthermore, a limiting plate is provided at the center of both ends of the base plate, and the limiting plate is used to restrict the position of the lower pressure plate.

[0009] Furthermore, there are multiple support rollers, which are equidistantly distributed on both sides of the lower pressure plate.

[0010] Furthermore, the length of the lower pressure plate is twice the length of the upper hot pressure plate.

[0011] Furthermore, the length of the slide rail is three times the length of the upper hot platen.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention, through the design of a base plate, an upper hot press plate, and a lower press plate, enables the fabric to be hot-pressed in a seat cushion fabric hot press machine to be laid flat on one side of the top of the lower press plate. A servo motor drives a gear to rotate, and through the meshing of the gear and rack, the lower press plate moves horizontally under the guidance of a slide rail, moving the fabric to be hot-pressed under the upper hot press plate. A hydraulic lifting cylinder then lowers the upper hot press plate to hot-press the fabric and maintain the pressure for a period of time. During the pressure-maintaining process, the next fabric to be hot-pressed can be placed on the other side of the top of the lower press plate. After the pressure maintenance is completed, the upper hot press plate rises and resets. At this time, the servo motor drives the lower press plate to move in the opposite direction, moving the fabric that has finished hot-pressing away from under the upper hot press plate, and the fabric to be hot-pressed enters under the upper hot press plate. Through the left and right horizontal movement of the lower press plate, the fabric hot-pressing can be continuously carried out, improving the efficiency of fabric hot pressing and facilitating the loading and unloading of fabric.

[0020] 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.

[0021] Please see Figures 1-4 This utility model provides a technical solution: a seat cushion fabric hot press machine, including: a base plate 1, a lower pressure plate 4, and an upper hot press plate 9. The base plate 1 has slide rails 2 on both sides of its top, and the lower pressure plate 4 is located on top of the slide rails 2. The slide rails 2 provide a track for the lower pressure plate 4 to move, allowing it to slide horizontally on the base plate 1. This facilitates continuous fabric loading and unloading and hot pressing operations, improving production efficiency. The base plate 1 has portal-shaped supports 5 on both sides of its middle section. These supports provide mounting support for components such as hydraulic lifting cylinders 6, ensuring the stability and reliability of the equipment structure and enabling the upper hot press plate 9 to rise and fall stably for hot pressing operations. The portal-shaped supports 5 have hydraulic lifting cylinders 6 on both sides of their top. These cylinders are the power source for driving the upper hot press plate 9 to rise and fall. Through hydraulic transmission, the upper hot press plate 9 moves up and down, providing greater pressure to ensure the fabric is fully hot pressed. The bottom of the piston rod of the hydraulic lifting cylinder 6 is equipped with a top plate 7. The top plate 7 serves to connect and transmit force, evenly transferring the thrust of the piston rod of the hydraulic lifting cylinder 6 to the upper hot press plate 9, ensuring uniform force distribution and consistent hot pressing effect. An elastic rubber pad 8 is located at the bottom of the top plate 7. The elastic rubber pad 8 has a cushioning effect, reducing the impact force when the upper hot press plate 9 contacts the lower press plate 4, preventing damage to the equipment due to impact. It also helps to ensure the flatness of the fabric during hot pressing, improving the quality of hot pressing. The upper hot press plate 9 is located at the bottom of the elastic rubber pad 8. The upper hot press plate 9 is the component that directly heats and presses the fabric, achieving the desired shape and properties through heating and pressurization. The uniformity of its temperature and pressure is crucial to the quality of the fabric.

[0022] The lower pressure plate 4 is longer than the upper hot pressure plate 9. This design allows the lower pressure plate 4 to have enough space to place the fabric to be hot-pressed and the fabric that has already been hot-pressed during its movement, which facilitates continuous loading and unloading of the fabric and improves production efficiency.

[0023] The slide rail 2 is equipped with support rollers 3, the top of which is fixedly connected to the lower pressure plate 4. A rack 13 is located on one side of the bottom of the lower pressure plate 4, and a servo motor 11 is located on one side of the top of the base plate 1. A gear 12 is located at the top of the output shaft of the servo motor 11, and the gear 12 meshes with the rack 13. The support rollers 3 reduce the friction between the lower pressure plate 4 and the slide rail 2, making the movement of the lower pressure plate 4 smoother, reducing energy consumption and wear, and extending the service life of the equipment. The servo motor 11, through the meshing transmission of the gear 12 and the rack 13, can precisely control the moving distance and speed of the lower pressure plate 4, achieving precise positioning of the fabric, ensuring the accuracy of the hot pressing position, and also facilitating automated production.

[0024] Limiting plates 10 are provided at the center of both ends of the base plate 1. The limiting plates 10 are used to limit the position of the lower pressure plate 4. The limiting plates 10 can prevent the lower pressure plate 4 from exceeding the range of the slide rail 2 during movement, avoid collision and damage to the equipment, and ensure the safe operation of the equipment.

[0025] There are multiple support rollers 3, which are equidistantly distributed on both sides of the lower pressure plate 4. The multiple equidistant support rollers 3 can more evenly distribute the weight of the lower pressure plate 4, making the movement of the lower pressure plate 4 more stable, further reducing friction and wear, and improving the operational stability of the equipment.

[0026] The lower pressure plate 4 is twice the length of the upper hot pressure plate 9. This proportional design allows the lower pressure plate 4 sufficient space for fabric placement and removal during the hot pressing process, while also ensuring adequate support area for the fabric, thus improving production continuity and efficiency. The slide rail 2 is three times the length of the upper hot pressure plate 9. The longer slide rail 2 provides the lower pressure plate 4 with a greater range of motion, allowing for sufficient space for fabric placement, movement, and removal during the hot pressing process, which is beneficial for continuous production and improves production efficiency.

[0027] When using the seat cushion fabric hot press machine, the fabric to be hot-pressed is laid flat on one side of the top of the lower press plate 4. The servo motor 11 drives the gear 12 to rotate. Through the meshing of the gear 12 and the rack 13, the lower press plate 4 moves horizontally under the guidance of the slide rail 2, so that the fabric to be hot-pressed moves to the bottom of the upper hot press plate 9. The hydraulic lifting cylinder 6 drives the upper hot press plate 9 to descend, hot-pressing the fabric and holding the pressure for a period of time. During the pressure holding process, the next fabric to be hot-pressed can be placed on the other side of the top of the lower press plate 4. After the pressure holding is completed, the upper hot press plate 9 rises and resets. At this time, the servo motor 11 drives the lower press plate 4 to move in the opposite direction. The fabric that has finished hot-pressing moves away from the bottom of the upper hot press plate 9, and the fabric to be hot-pressed enters the bottom of the upper hot press plate 9. By moving the lower press plate 4 left and right, the fabric hot-pressing can be carried out continuously, improving the fabric hot-pressing efficiency and facilitating the loading and unloading of the fabric.

[0028] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
