Description

Technical Field

[0001] This utility model relates to the technical field of desktop flexible plate hot press, specifically a desktop flexible plate hot press. Background Technology

[0002] In the field of flexible board processing, desktop hot presses are key equipment for bonding or molding flexible board materials. Due to their small size and convenient operation, they are widely used in small-batch production and laboratory research and development scenarios. Currently, desktop flexible board hot presses on the market usually include a frame, hot pressing components and drive components. The drive components drive the upper and lower molds to cooperate and complete the hot pressing processing of flexible board materials under high temperature and high pressure conditions. On the one hand, mold cleaning is cumbersome, and manual cleaning is inefficient and ineffective. During hot pressing, adhesive residue from the flexible board material surface easily remains on the lower mold surface. Simultaneously, dust and debris from the environment also adhere to the mold surface. If not cleaned promptly, this directly affects the bonding quality of subsequent flexible board products, leading to defects or even scrap. However, current hot presses generally lack dedicated cleaning mechanisms, requiring manual operation. Operators must repeatedly wipe the mold surface with cleaning tools, which is not only inconvenient, time-consuming, and labor-intensive, but also inefficient. Furthermore, manual cleaning struggles to ensure uniform cleanliness of the mold surface, especially around edges and corners, where the cleaning effect is often poor. This severely impacts the continuity of hot pressing and the product qualification rate. On the other hand, the lack of effective safety protection structures during the pressure holding process makes it easy for workers to feel uncomfortable due to the high temperature. During the pressure holding stage, the upper and lower molds of the hot press are at high temperatures, and there are no protective components at the front end. The high temperature will directly radiate outward. Workers need to observe the hot pressing situation during the pressure holding process, and inevitably have to get close to the front end of the hot press. Being in a high-temperature radiation environment for a long time can easily cause discomfort symptoms such as skin burning, dizziness, and weakness. This not only endangers the health of workers, but also reduces the safety of the operation. At the same time, the lack of protective structures cannot avoid the risk of burns caused by the high-temperature molds to workers in case of accidents, which poses a significant safety hazard. Utility Model Content

[0003] The purpose of this invention is to provide a desktop flexible plate hot press to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a desktop flexible plate hot press, comprising a hot press frame, a hot press assembly, and a drive component. The drive component is provided at the top of the hot press frame, and the hot press assembly is provided at the center of the bottom plate of the hot press frame. Sensors are provided on both sides of the hot press assembly, and slide rails are symmetrically arranged on both sides of the hot press assembly. A slider is slidably connected inside the slide rail, and a support rod is fixed at the top of the slider. A cleaning component is provided at the top of the support rod. A limit groove plate is provided on the front surface of the hot press frame column, and a through limit groove is opened inside the limit groove plate. A limit block is slidably connected up and down inside the limit groove plate, and a protective plate is provided on the inner side of the limit block. The bottom ends of both sides of the limiting groove plate are provided with sleeves, and the bottom ends of the sleeves are fixedly connected with springs. The top end of the springs is provided with pull ropes, and the pull ropes extend upwards to contact the guide rollers. The two sides of the guide rollers are connected to the limiting groove plate through bearing seats. The end of the pull rope away from the spring is fixedly connected to a connecting block, and the side wall of the connecting block is connected to the limiting block.

[0005] Preferably, the hot pressing assembly includes a lower mold, which is disposed at the center of the bottom plate of the hot press frame, and an upper mold is disposed at a corresponding position at the top of the lower mold, and the upper mold is connected to the driving end of the driving component.

[0006] Preferably, a moving track is provided at the connection between the lower mold and the hot press frame, and the lower mold can be moved horizontally on the moving track by a cylinder to facilitate material feeding.

[0007] Preferably, the cleaning assembly includes a cleaning rod, which is rotatably connected to the inner side of the support rod. Push rods are provided on both sides of the support rod, and the push rods extend upward to the top of the cleaning rod.

[0008] Preferably, the height of the cleaning roller corresponds to that of the lower mold, and the cleaning roller is made of polyurethane material.

[0009] Preferably, the protective plate is made of transparent acrylic material to protect against high temperatures during the pressure holding process.

[0010] Preferably, the front surface of the limiting groove plate is provided with a through hole, and a fixing pin is provided inside the through hole, which is used to fix the limiting block after it slides to a preset position by inserting the fixing pin inside.

[0011] Compared with the prior art, the beneficial effects of this utility model are: The cleaning component is guided by a slide rail and a slider to ensure the straightness of the cleaning component during movement, so that the cleaning roller can evenly fit the surface of the lower mold. This solves the problems of uneven cleaning and omissions that are easy to occur in traditional manual cleaning, and improves the cleaning accuracy and effect. The driving component drives the upper mold to move up and down in a linear motion, realizing the pressing and holding action of the flexible board. Combined with the heating function of the upper and lower molds, the flexible board material can be accurately bonded or formed under high temperature and high pressure. Compared with traditional hot pressing equipment, the pressure and temperature control is more precise, and the processed flexible board products have high dimensional accuracy, good bonding strength and excellent forming effect. The protective panel is made of transparent acrylic material, which not only effectively isolates the high temperature during the hot pressing and holding process to prevent operators from being burned, but also allows clear observation of the hot pressing process. This solves the problem of "protection and observation cannot be achieved at the same time" in traditional protective structures, and improves the safety and convenience of operation. The limiting groove plate provides vertical sliding guidance and limiting for the limiting block and the protective plate, ensuring that the protective plate moves smoothly in the vertical direction and avoids deviation or shaking. At the same time, the fixing pins fix the protective plate in the preset position to meet the protection and observation needs in different operating scenarios. The elastic auxiliary lifting structure, composed of sleeve, spring, pull rope, guide roller and connecting block, provides elastic auxiliary force for lifting the protective plate: when the protective plate is pulled up, the spring is compressed to generate elastic tension to assist in lifting and reduce the operating force. When the protective plate is released or the fixing pin is pulled out, the spring resets and drives the protective plate to automatically descend and reset. Compared with the traditional manual lifting of the protective plate, the operation is more labor-saving and efficient, and reduces the labor intensity of the operator. The cleaning roller is made of polyurethane, which has good elasticity and wear resistance. It can effectively remove dust, debris and residual adhesives and other contaminants from the surface of the lower mold without scratching the mold surface and extending the service life of the mold. The cleaning assembly has a cleaning roller mounted on the top of the support rod and push rods on both sides. The operator can move the support rod and slider along the slide rail by pushing the push rods, so that the cleaning roller can roll and clean the surface of the lower mold. The operation is simple and convenient, and the cleaning can be completed without disassembling the mold, which greatly shortens the equipment maintenance time and improves the equipment uptime.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-5 This utility model provides a technical solution for a desktop flexible board hot press: A desktop flexible board hot press includes a hot press frame 1, a hot press assembly, and a drive component 18. The top of the hot press frame 1 is provided with the drive component 18. The hot press frame 1 serves as the basic load-bearing structure of the entire hot press, supporting all components such as the drive component 18, the hot press assembly, the cleaning assembly, and the protective plate. The drive component 18 serves as the power source for the hot press action, driving the upper mold 4 to perform vertical linear motion to achieve the pressing and holding action of the flexible board. The hot press assembly is provided at the center of the bottom plate of the hot press frame 1, and sensors 2 are provided on both sides of the hot press assembly. The sensors 2 are used to detect whether there is a flexible board material to be hot-pressed on the lower mold 3, and whether the placement position of the flexible board material is correct. Slide rails 5 are symmetrically arranged on both sides of the hot press assembly. The slide rails 5 and sliders 6 provide guidance for the movement of the cleaning assembly. The cooperation between the slide rails 5 and sliders 6 ensures the straightness of the cleaning assembly during movement, so that the cleaning rollers 8 can clean the surface of the lower mold 3 evenly. The sliders 6 are slidably connected inside the slide rails 5. The top of the sliders 6 is fixed with a support rod 7. The support rod 7 serves as the mounting support structure for the cleaning rollers 8 and push rods 9. It is used to fix the cleaning rollers 8 at a height position corresponding to the lower mold 3, ensuring that the cleaning rollers can fully contact the surface of the lower mold and achieve an effective cleaning effect. The cleaning assembly is set at the top of the support rod 7. The front surface of the column of the hot press frame 1 is provided with a limiting groove plate 10, and the limiting groove plate 10 has a through limiting groove inside. The limiting groove plate 10 provides guidance and limitation for the upper and lower sliding of the limiting block 11 and the protective plate 12, ensuring that the protective plate 12 can move smoothly in the vertical direction and preventing the protective plate from shifting or shaking during movement. The limiting groove plate 10 is internally connected to a limiting block 11 that can slide up and down. The limiting block 11 is used to connect the limiting groove plate 10 and the protective plate 12, so that the protective plate can slide up and down in the limiting groove of the limiting groove plate through the limiting block to adjust the height of the protective plate. When the protective plate is adjusted to a suitable height, the fixing pin passes through the through hole of the limiting groove plate and the positioning hole of the limiting block to fix the limiting block, thereby fixing the position of the protective plate. The inner side of the limiting block 11 is provided with a protective plate 12, which plays a role in safety protection and observation during the pressure holding process of the hot press. Sleeves 13 are provided at the bottom ends of both sides of the limiting groove plate 10. The sleeves 13 provide installation space and protection for the spring 14. The spring 14 is fixedly connected to the bottom end of the sleeve 13. The spring 14 provides elastic auxiliary force for the lifting and lowering of the protective plate 12. When the operator pulls the protective plate 12 upward, the pull rope 15 drives the spring 14 to compress, and the spring 14 generates elastic tension, assisting the operator in lifting the protective plate and reducing the operating force. When the operator releases the protective plate or pulls out the fixing pin, the spring returns to its original position under the action of elastic force, pulls the pull rope 15, and thus drives the protective plate 12 to automatically descend. The top of the spring 14 is provided with a pull rope 15. The pull rope 15 extends upward and contacts the guide roller 16. The pull rope 15 serves as a force transmission component, connecting the spring 14, the guide roller 16, and the connecting block 17. It transmits the elastic force of the spring to the limiting block 11 and the protective plate 12, thereby achieving auxiliary lifting and lowering of the protective plate. The two sides of the guide roller 16 are connected to the limiting groove plate 10 through bearing seats. The end of the pull rope 15 away from the spring 14 is fixedly connected to the connecting block 17, and the side wall of the connecting block 17 is connected to the limiting block 11. The connecting block 17 serves as a connecting component between the pull rope 15 and the limiting block 11, transmitting the tension of the pull rope to the limiting block, thereby driving the protective plate 12 to move up and down.

[0016] The hot pressing assembly includes a lower mold 3, which is located at the center of the base plate of the hot press frame 1. The lower mold 3 serves as the lower support component during the hot pressing process, used to place the flexible board material to be hot-pressed, and to heat the flexible board through a heating plate. An upper mold 4 is provided at the corresponding position at the top of the lower mold 3, and the upper mold 4 is connected to the driving end of the driving component 18. The upper mold 4 and the lower mold 3 cooperate to clamp and heat the flexible board. The upper mold moves downward under the drive of the driving component 18, and together with the lower mold, applies pressure and heats the flexible board, so that the flexible board material is bonded or formed under high temperature and high pressure. A moving track is provided at the connection between the lower mold 3 and the hot press frame 1. The lower mold 3 can be moved horizontally on the moving track by a cylinder to facilitate material feeding.

[0017] The cleaning assembly includes a cleaning roller 8, which is rotatably connected to the inner side of the support rod 7. The cleaning roller 8 is used to clean dust, debris, and residual adhesive and other contaminants from the surface of the lower mold 3. Push rods 9 are provided on both sides of the support rod 7, and the push rods 9 extend upward above the cleaning roller 8. The push rods 9 provide convenient operating parts for the operator. By pushing the push rods 9, the operator can drive the support rod 7 and the slider 6 to move along the slide rail 5, thereby causing the cleaning roller 8 to roll on the surface of the lower mold 3 to complete the cleaning action. The height of the cleaning roller 8 corresponds to that of the lower mold 3, and the cleaning roller 8 is made of polyurethane. The protective plate 12 is made of transparent acrylic material to protect against high temperatures during the pressure holding process. The front surface of the limiting groove plate 10 has a through hole, and a fixing pin is provided inside the through hole. After the limiting block 11 slides to the preset position, the fixing pin is inserted into it to fix it.

[0018] Working principle: When a desktop flexible board hot press is first used, the lower mold 3 is driven by a cylinder to move horizontally along the bottom moving track out of the hot pressing area in the center of the base plate of the hot press frame 1, making it convenient for the operator to place the flexible board material to be hot pressed; after the operator places the flexible board material on the surface of the lower mold 3, the cylinder drives the lower mold 3 to return to the hot pressing area along the moving track again. At this time, sensors 2 located on both sides of the hot pressing assembly start working, accurately detecting whether flexible plate material has been placed on the lower mold 3, and simultaneously determining whether the placement position of the flexible plate material meets the hot pressing requirements. If no material is detected or the position is offset, the equipment will issue a warning signal to avoid invalid hot pressing or product damage. After the material is detected as qualified, the operator needs to pull the protective plate 12 upwards. During the pulling process, the protective plate 12 drives the pull rope 15 to move through the limit block 11 and the connecting block 17. The pull rope 15 changes the direction of force along the guide roller 16, thereby pulling the spring 14 in the sleeve 13 to stretch. When the protective plate 12 is pulled down to a suitable observation height, the fixing pin is inserted into the through hole of the limit slot plate 10 and the positioning hole of the limit block 11 to achieve the protection. With the protective plate 12 fixed in position, it neither affects the hot pressing action nor hinders the operator's observation of the hot pressing process through its transparent acrylic material. It also serves as a safety barrier against high temperatures. After the protective plate is fixed, the drive unit 18 is activated, acting as the power source for the hot pressing action and driving the upper mold 4 to move vertically downwards. When the upper mold 4 contacts the flexible material on the surface of the lower mold 3, the drive unit 18 continuously outputs power to apply pressure. Simultaneously, the heating plates inside the upper mold 4 and lower mold 3 begin to work, heating the flexible material. Under the combined action of high temperature and high pressure, the flexible material undergoes a bonding or molding reaction. The drive unit 18 maintains pressure to complete the pressure holding process, ensuring the quality of the flexible material processing. After the pressure holding period ends, the drive component 18 drives the upper mold 4 to return to its initial standby position. After the hot pressing is completed, the operator pulls out the fixing pin, and the spring 14 returns to its original position under the action of elastic force. The protective plate 12 is automatically raised and fixed by the pull rope 15, connecting block 17, and limit block 11. Subsequently, the operator pushes the push rod 9 of the cleaning component. The push rod 9 drives the support rod 7 and the bottom slider 6 to move linearly along the slide rail 5. The cooperation between the slide rail 5 and the slider 6 ensures the straightness of the movement process, so that the cleaning roller 8 connected to the inner side of the support rod 7 can roll evenly against the surface of the lower mold 3. The cleaning roller 8 is made of polyurethane material. During the rolling process, it removes dust, debris, adhesive and other contaminants remaining on the surface of the lower mold 3, providing a clean mold surface for the next hot pressing operation.
