Description

Technical Field

[0001] This invention relates to the field of metal plate processing technology, specifically to a fully automatic metal tablet press. Background Technology

[0002] Metal pressing machines are core equipment for the precision processing of metal sheets. They mainly use a pair of counter-rotating pressing rollers to roll and thin thick metal sheets, pressing the original metal sheets into thin sheets that meet the size requirements. They are widely used in hardware processing, new energy housings, precision sheet metal and other industries. At present, conventional fully automatic metal pressing machines on the market still have many technical defects in actual production operations, making it difficult to meet the needs of high-precision, continuous and long-term industrial production.

[0003] However, existing fully automatic metal tablet presses still have some problems in use: An existing precious metal tablet press, as described in Chinese Patent Application No. CN201820526001.3, includes a frame, on which a tablet pressing roller assembly for extruding precious metal sheets and a drive device for driving the tablet pressing roller assembly to rotate are mounted. The tablet pressing roller assembly includes an upper roller and a lower roller. The drive device is a drive motor for driving the upper roller and the lower roller to rotate. A bracket for supporting the tablet pressing roller assembly is mounted on the frame. A roller gap adjustment device for adjusting the distance between the upper roller and the lower roller is mounted above the bracket. A reinforcing plate for supporting the precious metal sheets is provided between the upper roller and the lower roller. The reinforcing plate is fixed to the bracket.

[0004] However, most existing metal tablet presses operate with a single rotating roller, which is prone to slippage during the feeding process of metal tablets. Traditional tablet presses mostly use solid rollers, which generate a lot of extrusion friction heat during the rolling process of metal sheets. The heat of the roller cannot be dissipated quickly, and long-term high-temperature operation will not only cause processing defects such as roller sticking, indentation, and deformation on the surface of the metal sheet.

[0005] To address the aforementioned issues, an innovative design was implemented based on the existing fully automatic metal tablet press. Summary of the Invention

[0006] The purpose of this invention is to provide a fully automatic metal tablet press to solve the problems mentioned in the background art, where most existing metal tablet presses operate with a single roller rotation. During the metal tablet feeding process, slippage is likely to occur, and the heat of the solid tablet roller cannot be dissipated quickly. Long-term high-temperature operation will not only cause processing defects such as roller sticking, indentation, and deformation on the surface of the metal sheet.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a fully automatic metal tablet press, comprising a support platform and a support plate symmetrically installed on its left side, wherein guide rollers are arrayed inside the support plate. The upper right side of the support platform is fixed with a work box, which contains two sets of tableting rollers. A drive shaft is connected to the middle of the tableting rollers, and a drive assembly is connected to the lower end of the drive shaft. The drive assembly can drive the tableting rollers to rotate. The right side of the work box is provided with a through groove, through which a first transmission roller passes. The lower end of the first transmission roller is connected to a second transmission roller. The ends of the first transmission roller are respectively connected to the tableting rollers with transmission components. The transmission components can keep the two sets of tableting rollers rotating synchronously in opposite directions. Limiting sliders are slidably installed on both sides of the working box. The upper drive shaft is rotatably connected to the limiting sliders. An adjustment component is connected to the end of the upper drive shaft. The adjustment component can adjust the height of the upper drive shaft, thereby adjusting the distance between the two sets of tableting rollers. The tableting roller has a liquid storage chamber inside, and fins are connected to the inner wall of the liquid storage chamber. The tableting roller has a hollow design and a through hole at the end. A flow guiding component is provided inside the tableting roller to accelerate the airflow inside the tableting roller.

[0008] Preferably, the drive assembly includes a drive motor, with a drive pulley connected to the end of the drive motor shaft, a driven pulley connected to the rear end of the lower drive shaft, and a drive belt connecting the driven pulley and the drive pulley.

[0009] The above technical solution uses a belt drive structure composed of pulleys and a drive belt to provide stable power to the lower pressing rollers via a drive motor. This transmission structure is simple in structure, easy to install and maintain, has low transmission noise, is suitable for continuous metal pressing operations, can stably output torque, ensure uniform speed operation of the pressing rollers, and ensure uniform thickness of the metal sheet pressing.

[0010] Preferably, the adjustment assembly includes an adjustment link disposed on the side of the work box. The left end of the adjustment link is rotatably connected to a positioning shaft, which is fixed to the outer wall of the work box. An adapter rod is embedded in the left end of the adjustment link, and the left end of the adapter rod is rotatably connected to the end of the transmission shaft. An electric push rod is rotatably mounted on the outer side of the upper end of the work box, and the end of the telescopic shaft of the electric push rod is rotatably connected to the right end of the adjustment link.

[0011] The above technical solution utilizes a lever-type adjustment structure composed of an electric push rod, an adjusting link, and an adapter rod. The extension and retraction of the electric push rod drives the adjusting link to rotate around the positioning shaft, thereby precisely controlling the lifting height of the upper pressing roller. The overall adjustment requires no manual operation, has a high degree of automation, and is suitable for the pressing needs of metal sheets of different thicknesses. The adapter rod can adapt to the displacement deviation of the transmission shaft, eliminating the mechanical jamming problem during the adjustment process and improving the smoothness of gap adjustment and the stability of equipment operation.

[0012] Preferably, the adjusting rods are symmetrically distributed on both sides of the work box, and a connecting rod is connected between the top of the adjusting rods.

[0013] By adopting the above technical solution, a connecting rod is added to the top of the symmetrically distributed adjusting rods on both sides, which can realize the synchronous linkage of the adjusting rods on both sides of the working box, so that the height of the two ends of the upper drive shaft is completely consistent, avoiding the problems of tablet roller tilting and uneven gap at both ends that occur when adjusting on one side, balancing the force on both sides of the adjustment, reducing the deformation loss of the connecting rod on one side, extending the overall service life of the adjusting component, and ensuring the tablet pressing accuracy.

[0014] Preferably, the first transmission roller is rotatably connected to two sliding plates on both sides, the upper end of the sliding plates extends into the through groove and slides in cooperation with the slide rail, the slide rail is horizontally set, the lower ends of the two sets of sliding plates are provided with rectangular grooves, and sliding blocks are slidably installed in the rectangular grooves. The two ends of the second transmission roller are respectively rotatably connected to the two sets of sliding blocks.

[0015] Using the above technical solution, the sliding plate and the slide rail enable the first transmission roller to slide horizontally, and the sliding block and the rectangular groove enable the second transmission roller to adapt to vertical displacement. The two sets of transmission rollers can automatically adjust their relative positions according to the thickness of the metal sheet, which can not only ensure the smooth conveying of the sheet, but also adapt to the discharge conveying path after the change of the gap of the pressing roller, avoiding bending, deviation and jamming of the sheet conveying. At the same time, the sliding structure has strong compatibility and can be synchronized with the adjustment action of the gap of the pressing roller, improving the linkage and coordination of the whole machine.

[0016] Preferably, a first compression spring is connected to the inner wall of the rectangular groove, and the top of the first compression spring is connected to the sliding block.

[0017] By adopting the above technical solution, a first pressure spring is installed inside the rectangular groove, which can continuously apply downward elastic pressure to the sliding block and the second transmission roller, so that the second transmission roller always fits against the lower surface of the metal plate.

[0018] Preferably, the transmission assembly includes a drive gear, which is fixed to the end of the lower transmission shaft. A driven gear meshes with the lower end of the drive gear, and the driven gear is rotatably mounted on the outer wall of the work box. The driven gear, the upper transmission shaft, and the first transmission roller are distributed in an isosceles triangle shape. A transmission connecting plate connects the driven gear, the upper transmission shaft, and the end of the first transmission roller. The driven gear, the upper transmission shaft, and the first transmission roller are all rotatably connected to the transmission connecting plate. The drive shaft and driven gear at the upper end are respectively connected to the first drive roller by belt sets.

[0019] By adopting the above technical solution, a linkage transmission system is formed by gear meshing, belt assembly, and transmission connecting plate. Without the need for additional drive source, the upper and lower sets of tableting rollers can rotate synchronously in opposite directions. The transmission structure with isosceles triangular layout is subjected to balanced force. The transmission connecting plate can be adapted to the lifting and lowering displacement of the upper tableting roller. During the gap adjustment process, the transmission structure will not derail or slip off the belt, and always maintain transmission synchronization. This simplifies the overall power structure of the machine, reduces equipment manufacturing costs and energy consumption, and ensures precise and synchronized operation of the tableting rollers.

[0020] Preferably, the left end of the work box has limiting grooves on both sides, and two sets of feeding rollers are symmetrically distributed inside the limiting grooves. The two ends of the feeding rollers are rotatably connected to a second slider, which slides in cooperation with the inner wall of the limiting groove. A second pressure spring is fixed to the inner wall of the limiting groove.

[0021] Using the above technical solution, the upper and lower sliding feeding rollers, together with the second pressure spring, can adapt to the thickness changes of the metal sheet to be processed. The spring continuously provides clamping force, so that the feeding end always clamps the sheet, which can effectively correct the positional deviation of the sheet during feeding and prevent the sheet from entering the pressing roller at an angle, causing the pressed defective products to collide and damage the equipment.

[0022] Preferably, the fins are arranged in a ring array around the center of the tableting roller, a side cover is rotatably mounted on the right side of the tableting roller, the side cover is fixed to the front limiting slider, the side cover has a through hole, and the side cover is rotatably connected to the drive shaft.

[0023] The above technical solution maximizes the heat exchange area by arranging the fins in annular array, improves the heat exchange efficiency of the coolant inside the tableting roller, and quickly removes the large amount of heat generated by the metal tableting. The side cover is fixed to the limiting slider and rotates with the drive shaft to avoid interfering with the rotational movement of the drive shaft and the tableting roller. The through holes in the side cover allow for smooth airflow, ensuring the normal operation of the internal flow guiding components and taking into account sealing, heat dissipation, and rotational compatibility.

[0024] Preferably, the flow guiding assembly includes a fan blade, which is rotatably mounted on the inner end of the side cover. A drive shaft passes through the middle of the fan blade. A first gear is fixed on the side of the fan blade, and a second gear meshes with the upper end of the first gear. The second gear is rotatably mounted on the inner side of the side cover. A drive gear ring is fixed on the inner wall of the pressure roller, and the drive gear ring meshes with the second gear.

[0025] By adopting the above technical solution, the drive shaft rotates to drive the gear set to drive the fan blades to rotate autonomously. There is no need to install additional power components such as fans. This can accelerate the air convection inside the tableting roller. The high-speed airflow, combined with the fins to enhance the heat dissipation effect, quickly removes the working heat of the tableting roller and avoids the metal sheet sticking to the roller and tablet deformation caused by overheating of the roller body.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows: This fully automatic metal tablet press, equipped with a lever-type electric gap adjustment structure, and with double-sided synchronous connecting rods and limit sliders, can automatically and accurately adjust the gap between the tablet pressing rollers. Moreover, the transmission connecting plate can adapt to the lifting and lowering displacement of the rollers. During the gap adjustment process, the transmission structure will not detach or lose teeth, which completely solves the problems of transmission failure, roller skewing, and uneven plate thickness after gap adjustment in traditional tablet presses, and greatly improves the precision of metal plate tableting.

[0027] 1. The equipment is equipped with a floating feed roller with springs at the feeding end and a double drive roller structure that can slide horizontally and float vertically at the discharging end. Both the front and rear conveying mechanisms can be automatically and adaptively adjusted according to the thickness of the sheet material, eliminating the need for manual adjustment of the conveying roller spacing. The discharging end always clamps the sheet material to prevent slippage and deviation. The entire process of feeding, pressing, and discharging is fully automated, reducing manual alignment and correction processes. It is suitable for continuous production lines and effectively improves the overall processing efficiency. 2. The tableting roller integrates a liquid-cooled storage chamber, heat dissipation fins, and gear-driven self-driving guide fan blades. There is no need to add external heat dissipation power components such as fans. The rotation power of the tableting roller itself can drive the fan blades to exhaust air at high speed, forming a liquid-cooled and air-cooled composite heat dissipation system. This can quickly remove the frictional heat generated by the roller pressing, avoid defects such as the plate sticking to the roller and surface indentation deformation caused by high temperature of the roller body, and at the same time slow down the high temperature wear of the roller body, effectively extend the service life of the tableting roller, and ensure the long-term uninterrupted and stable operation of the equipment.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figure 1-10 This invention provides a technical solution: a fully automatic metal tablet press, comprising a support platform 1 and a support plate 2 symmetrically installed on its left side. Guide rollers 3 are arrayed inside the support plate 2. A work box 4 is fixed to the upper right side of the support platform 1. Two sets of tablet pressing rollers 6 are arranged inside the work box 4. A drive shaft 5 is connected to the middle of the tablet pressing rollers 6, and a drive assembly is connected to the lower end of the drive shaft 5. The drive assembly can drive the tablet pressing rollers 6 to rotate. The drive assembly includes a drive motor 7, with a drive pulley 8 connected to the shaft end of the drive motor 7. A driven pulley 9 is connected to the rear end of the lower drive shaft 5, and a drive belt 10 connects the driven pulley 9 and the drive pulley 8. The drive motor 7 is fixed to the rear outer wall of the work box 4 via a motor support. The output shaft of the drive motor 7 is coaxially fixedly connected to the drive pulley 8. The driven pulley 9 is coaxially fixedly mounted at the rear end of the lower drive shaft 5, and the drive belt 10 is tensioned and sleeved between the drive pulley 8 and the driven pulley 9. When the equipment is working, the drive motor 7 is started. The drive motor 7 drives the active pulley 8 to rotate synchronously. The friction of the transmission belt 10 drives the driven pulley 9 to rotate, which in turn drives the lower transmission shaft 5 and the lower pressing roller 6 to rotate at a constant speed. The belt drive has the effects of buffering and shock absorption and overload protection, effectively protecting the drive motor 7 and the transmission shaft 5 from damage by torque impact. The operating noise is lower and the maintenance and disassembly are convenient.

[0032] Limiting sliders 22 are slidably installed on both sides of the work box 4. The upper drive shaft 5 is rotatably connected to the limiting sliders 22. An adjustment component is connected to the end of the upper drive shaft 5. The adjustment component can adjust the height of the upper drive shaft 5, thereby adjusting the distance between the two sets of pressing rollers 6. The adjustment component includes an adjustment rod 23, which is located on the side of the work box 4. A positioning shaft 24 is rotatably connected to the left end of the adjustment rod 23. The positioning shaft 24 is fixed to the outer wall of the work box 4. An adapter rod 25 is embedded in the left end of the adjustment rod 23. The left end of the adapter rod 25 is rotatably connected to the end of the drive shaft 5. An electric push rod 26 is rotatably installed on the upper outer side of the work box 4. The end of the telescopic shaft of the electric push rod 26 is rotatably connected to the right end of the adjustment rod 23. The adjustment rods 23 are symmetrically distributed on both sides of the work box 4. A connecting rod is connected between the tops of the adjustment rods 23. By extending and retracting the electric push rod 26 to push the adjusting linkage 23 to rotate around the positioning shaft 24, the upper transmission shaft 5 and the upper pressure roller 6 can be driven to rise and fall, precisely adjusting the roller gap between the two sets of pressure rollers 6. This is suitable for processing metal sheets of different thicknesses. The entire process is electrically controlled and automatically adjusted, eliminating the need for manual adjustment. The adjustment accuracy is higher, and it can ensure that the two ends of the pressure roller 6 are level. The upper limit slider 22 can improve the stability of the upper pressure roller 6.

[0033] The right side of the work box 4 has a through groove 11, through which a first transmission roller 13 passes. The lower end of the first transmission roller 13 is connected to a second transmission roller 14. Slide plates 12 are rotatably connected to both sides of the first transmission roller 13. The upper end of the slide plate 12 extends into the through groove 11 and slides in cooperation with the slide rail 17. The slide rail 17 is horizontally set. Rectangular grooves are opened at the lower ends of the two sets of slide plates 12. Sliding blocks 15 are slidably installed inside the rectangular grooves. The two ends of the second transmission roller 14 are rotatably connected to the two sets of sliding blocks 15 respectively. A first pressure spring 16 is connected to the inner wall of the rectangular groove. The top of the first pressure spring 16 is connected to the sliding block 15.

In order to keep the two sets of metal sheets tightly attached, a first pressure spring 16 is provided. The sliding block 15 and the second drive roller 14 can slide inside the rectangular groove to adapt to the guiding and conveying of metal sheets of different thicknesses.

[0034] Limiting grooves are provided on both sides of the left end of the work box 4. Two sets of feeding rollers 27 are symmetrically distributed inside the limiting grooves. The two ends of the feeding rollers 27 are rotatably connected to the second sliders 28. The second sliders 28 slide in cooperation with the inner wall of the limiting groove. A second pressure spring 29 is fixed to the inner wall of the limiting groove. The two sets of sliding feeding rollers 27, in cooperation with the second pressure springs 29, can adapt to the thickness changes of the metal sheet to be processed. The second pressure springs 29 continuously provide clamping force, so that the feeding end always clamps the sheet, which can effectively correct the positional deviation of the sheet during feeding and prevent the sheet from entering the pressing roller 6 at an angle, causing the pressed defective products to collide with and damage the equipment.

[0035] The ends of the first drive roller 13 are connected to the tableting rollers 6 by transmission components. These transmission components ensure that the two sets of tableting rollers 6 rotate synchronously in opposite directions. Each transmission component includes a drive gear 20, which is fixed to the end of the lower drive shaft 5. A driven gear 21 meshes with the lower end of the drive gear 20. The driven gear 21 is rotatably mounted on the outer wall of the work box 4. The driven gear 21, the upper drive shaft 5, and the first drive roller 13 are arranged in an isosceles triangle shape. A transmission connecting plate 19 connects the driven gear 21, the upper drive shaft 5, and the end of the first drive roller 13. The driving shaft 5 and the first transmission roller 13 are rotatably connected to the transmission connecting plate 19. A belt assembly 18 connects the upper transmission shaft 5 and the driven gear 21 to the first transmission roller 13. The transmission assembly maintains stable and reliable transmission after the distance between the two sets of pressure rollers 6 is adjusted. The driven gear 21, the upper transmission shaft 5, and the first transmission roller 13 are connected via the transmission connecting plate 19, maintaining effective connection of the belt assembly 18. The belt assembly 18 includes two sets of pulleys and belts. The driven gear 21, the upper transmission shaft 5, and the ends of the first transmission roller 13 are all connected to pulleys, which are connected by belts. When the pressure roller 6 rises and falls, the transmission connecting plate 19 drives the sliding plate 12 to slide horizontally within the through groove 11, thereby maintaining synchronous transmission of the two sets of pressure rollers 6.

[0036] The tablet compression roller 6 has a liquid storage chamber 30 inside, and fins 31 are connected to the inner wall of the liquid storage chamber 30. The tablet compression roller 6 has a hollow design and a through hole at the end. A flow guiding component is provided inside the tablet compression roller 6 to accelerate the airflow inside the tablet compression roller 6. The fins 31 are arranged in a ring array around the center of the tablet compression roller 6. A side cover 32 is rotatably installed on the right side of the tablet compression roller 6. The side cover 32 is fixed to the front limiting slider 22. The side cover 32 has a through hole and is rotatably connected to the drive shaft 5. The flow guiding component includes a fan blade 33, which is rotatably installed on the inner end of the side cover 32. The drive shaft 5 passes through the middle of the fan blade 33. A first gear 34 is fixed on the side of the fan blade 33. A second gear 35 meshes with the upper end of the first gear 34. The second gear 35 is rotatably installed on the inner side of the side cover 32. A transmission gear ring 36 is fixed on the inner wall of the tablet compression roller 6 and meshes with the second gear 35. To prevent the tableting roller 6 from continuously heating up during long-term operation, a cooling structure is provided for the tableting roller 6. A liquid storage chamber 30 is provided inside the tableting roller 6, and a coolant is provided inside the liquid storage chamber 30. The coolant absorbs the heat generated by the metal tableting and, together with the fins 31, guides the heat into the interior of the tableting roller 6. When the tableting roller 6 and the drive shaft 5 connected to it rotate, the drive gear ring 36 connected to the inner wall of the tableting roller 6 drives the second gear 35 connected to the inner side of the side cover 32 to rotate synchronously. The second gear 35 drives the first gear 34 and the fan blade 33 to rotate synchronously. The fan blade 33 drives the air to flow rapidly inside the tableting roller 6, thereby accelerating the heat dissipation and achieving continuous cooling of the tableting roller 6.
