Description

Technical Field

[0001] This utility model relates to the field of hot stamping machine technology, specifically a small metal flat hot stamping machine. Background Technology

[0002] Hot stamping machines apply metal foil or other special materials to the surface of printed materials to enhance their decorative effect and texture. Hot stamping makes QR codes on steel plates clearer and easier for customers to identify. In the prior art, patent publication number CN 222780140 U discloses a small flat hot stamping machine, including a hot stamping mechanism, a heating mechanism, and a temperature control mechanism. The hot stamping mechanism includes two support plates, a controller and a hydraulic cylinder connected between the two support plates, a pressure plate connected to the movable end of the hydraulic cylinder, and a hot stamping plate detachably connected to the pressure plate. The hydraulic cylinder is electrically connected to the controller. In this invention, multiple ceramic heating elements work together to heat each position on the top of the hot stamping plate. The heat then passes through the filler in the main vein, side vein, and fine vein to rapidly heat the entire hot stamping plate. During this process, an infrared thermal imager provides real-time feedback on the temperature around each ceramic heating element to the PID temperature control module. Based on the feedback data, the PID temperature control module adjusts the ceramic heating elements with abnormal temperatures to achieve a dynamic temperature compensation mechanism. Compared to traditional electric heating technology, this method offers rapid and uniform heating, ensuring hot stamping quality. However, when hot stamping steel plates, the device lacks a hot stamping limiting element, which can cause the hot stamping position to shift, affecting the hot stamping effect. Furthermore, the device lacks an automatic feeding device for hot stamping steel plates, increasing the labor intensity of workers. Therefore, we propose a small metal flat hot stamping machine.

Detailed Implementation

[0021] 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.

[0022] Please see Figure 1-5 This embodiment provides a technical solution: a small metal flat hot stamping machine, including a platform 1, a hot stamping plate 6 mounted on the upper side of the platform 1, a feeder 8 located in the middle of the upper side of the platform 1, a laser sensor 3 11 located in the middle of the upper rear end of the feeder 8, and a microcontroller 2 located outside the platform 1. The input end of the microcontroller 2 is electrically connected to an external power supply, the input end of the feeder 8 is electrically connected to the output end of the microcontroller 2, the laser sensor 3 11 is bidirectionally electrically connected to the microcontroller 2, a bracket 3 is located at the upper rear end of the platform 1, a connecting seat 5 is located on the upper side of the bracket 3 via the telescopic end of an electro-hydraulic push rod 4, the lower side of the connecting seat 5 is fixedly connected to the upper side of the hot stamping plate 6, a ceramic heating element 7 is located inside the hot stamping plate 6, and the input ends of the ceramic heating element 7 and the electro-hydraulic push rod 4 are both electrically connected to the output end of the microcontroller 2. The upper side of the connecting seat 5 is provided with a laser sensor 13 and a horizontally symmetrical guide rod 12. The upper ends of the guide rods 12 are slidably connected to the round holes 2 on the bracket 3. The upper part of the inside of the feeder 8 is provided with a horizontally symmetrical support rod 10. The support rod 10 is installed in conjunction with the belt of the feeder 8. The laser sensor 13 is bidirectionally electrically connected to the microcontroller 2. The left and right sides of the bracket 3 are provided with fixed seats 14. The front side of the fixed seat 14 on the right side is rotatably connected to a vertically symmetrically distributed feed roller 16 through a rotating shaft 15. The rear side of the fixed seat 14 on the right side is provided with a brake motor 17. The input end of the brake motor 17 is electrically connected to the output end of the microcontroller 2. The output shaft of the brake motor 17 is fixedly connected to the rear end of the rotating shaft 15 on the upper side. The front side of the fixed seat 14 on the left side is rotatably connected to a feeding plate 18 through a damping shaft.

[0023] The dimensions of the steel plate are entered into the microcontroller 2. When performing hot stamping on the marking areas of the steel plate, the steel plate is first fed at equal intervals onto the left end of the conveyor belt of the feeder 8 via an external feeding device. A roll of electroplated aluminum foil is placed on the feeding tray 18. The operator presses the initial end of the roll of electroplated aluminum foil from below the hot stamping plate 6 into the feeding gap between the two feeding rollers 16. Then, the microcontroller 2 starts the feeder 8, which transports the steel plate from left to right via its own belt. Simultaneously, the microcontroller 2 activates the laser sensor 11, which emits a light signal that illuminates the upper edge of the front wall of the feeder 8 and reflects back to the initial position. The distance between the two points is detected based on the light signal's propagation time and speed, and the detection result is recorded. The signal is transmitted to the microcontroller 2 via electrical signal. When the rightmost end of the steel plate passes the position of the laser sensor 311 along with the conveyor belt of the feeder 8, the detection result of the laser sensor 311 changes. At this time, the microcontroller 2 starts timing through its internal timing unit. At the same time, the microcontroller 2 divides the transverse width of the steel plate by two to obtain the corresponding value. Then, based on this value and the material conveying speed of the feeder 8 per unit time, the microcontroller 2 controls the continued running time of the feeder 8 through its own timing unit. This ensures that the feeder 8 stops running when the middle of the steel plate is roughly below the hot stamping plate 6 along with the conveyor belt of the feeder 8. Two sets of support rods 10 support the steel plate on the underside of the conveyor belt at this part of the feeder 8, preventing the steel plate from being pressured and causing the belt to sink during the subsequent hot stamping process.

[0024] After the hot stamping of the steel plate is completed, the microcontroller 2 activates the electro-hydraulic actuator 4, causing its telescopic end to move the hot stamping plate 6 vertically downwards via the connecting seat 5. Simultaneously, the microcontroller 2 activates the ceramic heating element 7 to heat the hot stamping plate 6. After the hot stamping plate 6 moves vertically downwards a certain distance, it moves the electroplated aluminum foil below it vertically downwards and stamps it onto the lower steel plate, thus achieving the marking and hot stamping operation on the steel plate. During this process, the microcontroller 2 activates itself, emitting a light signal that illuminates the top wall of the bracket 3 and reflects back to the initial position. The vertical movement distance of the hot stamping plate 6 is measured using the same principle, and the measurement result is transmitted electronically. The signal is transmitted to the microcontroller 2. The microcontroller 2 controls the extension and retraction stroke of the electro-hydraulic push rod 4 based on the measurement results. During the vertical movement of the hot stamping plate 6, the guide rod 12 is driven by the connecting seat 5 to slide adaptively along the corresponding circular hole 2, thereby improving the vertical stability of the hot stamping plate 6. After the hot stamping is completed on the steel plate surface, the microcontroller 2 controls the corresponding electrical components inside the device to move the hot stamping plate 6 upward and reset it through the same principle. Then, the microcontroller 2 starts the brake motor 17 so that its output shaft drives the corresponding feed roller 16 to rotate in the reverse direction through the rotating shaft 15 (after the brake motor 17 is powered on, the armature inside the brake motor 17 is electromagnetically attracted). This allows the brake disc to be rotatable and the brake motor 17 to rotate freely. When the brake motor 17 is de-energized, the electromagnet is de-energized, and the armature is immediately pressed by the spring, causing the brake disc to press against the rear end cover of the motor and stop rotating. Therefore, the output shaft of the brake motor 17 has a self-locking function. Through the contact friction between the upper feed roller 16 and the electroplated aluminum foil during the reverse process, the electroplated aluminum foil is conveyed to the right, replacing the used electroplated aluminum foil below the hot stamping plate 6. The used electroplated aluminum foil at the right end of the feed roller 16 is collected by the external waste roll. During the rightward movement of the electroplated aluminum foil, the discharge tray 18 is connected by an electric current. The aluminum foil feeding device uses the traction force to overcome the resistance of the damping shaft and rotates to feed the material. The damping shaft mainly consists of a damping device, a rotating shaft, and an adjustment mechanism. The damping device is fixedly connected to the front surface of the corresponding fixed seat 14. When the damping shaft rotates, the damping device applies resistance in the opposite direction of rotation through the damping material, so that the feeding tray 18 can stop rotating in time. At the same time, the microcontroller 2 controls the corresponding electrical components in the device to automatically replace the steel plate fixed in the limit mechanism 9 through the same principle, in preparation for the next marking and hot stamping on the surface of the steel plate. This device can automatically perform marking and hot stamping feeding operations on the steel plate through the feeding device.

[0025] It also includes a limiting mechanism 9, which comprises a fixed base 91, an electro-hydraulic actuator 92, and a limiting assembly 93. The fixed bases 91 are symmetrically arranged longitudinally on the upper side of the platform 1. Electro-hydraulic actuators 92 are provided on opposite surfaces of the two fixed bases 91. Each telescopic end of the electro-hydraulic actuator 92 is provided with a limiting assembly 93. The input ends of the electro-hydraulic actuators 92 are electrically connected to the output end of the microcontroller 2. The limiting assembly 93 includes a longitudinal sliding plate 931, a sliding groove 932, and a sliding... The system comprises a seat 933, a transverse limiting plate 934, and a longitudinal limiting seat 935. A longitudinal moving plate 931 is respectively disposed at the telescopic end of the electro-hydraulic actuator 92. Two transversely symmetrically distributed sliding seats 933 are slidably connected within a groove 932 formed in the middle of the longitudinal moving plate 931. A transverse limiting plate 934 is provided at the opposite ends of two adjacent transversely arranged sliding seats 933, and a longitudinal limiting seat 935 is provided on the opposite inner surfaces of two adjacent longitudinally arranged sliding seats 933. The limiting assembly 93 also includes... The limiting mechanism 9 includes insertion holes 936 and locking bolts 937. The insertion holes 936 are evenly distributed on opposite surfaces of the two longitudinal sliding plates 931. The opposite surfaces of the two longitudinally adjacent sliding blocks 933 are threaded with locking bolts 937, and the locking bolts 937 are inserted into the adjacent insertion holes 936. The limiting mechanism 9 also includes a laser sensor 1 94, a laser sensor 2 95, and a guide rod 1 96. The laser sensor 1 94 is respectively set in the middle of the opposite surfaces of the two longitudinal sliding plates 931. The laser sensor 2 95 is provided in the groove on the front side of the rear longitudinal sliding plate 931. The laser sensor 2 95 and the laser sensor 1 94 are both bidirectionally electrically connected to the microcontroller 2. The opposite surfaces of the two longitudinal sliding plates 931 are provided with transversely symmetrically distributed guide rods 1 96. The guide rods 1 96 are slidably connected to the round holes 1 on the adjacent fixed bases 1 91. The microcontroller 2 activates the electro-hydraulic push rod 2 92 so that its extension end drives the corresponding longitudinal sliding plate 931 to move synchronously toward the longitudinal center of the device.

[0026] Initially, the microcontroller 2 activates laser sensor 95, which emits a light signal that illuminates the front longitudinal moving plate 931 and reflects back to its initial position. The signal emitting end of laser sensor 95 vertically aligns with the front of the rear longitudinal moving plate 931. Based on the propagation speed and time of the light signal, the longitudinal distance between the two longitudinal moving plates 931 is obtained, and this result is transmitted to the microcontroller 2 as an electrical signal. The microcontroller 2 subtracts the longitudinal width of the steel plate from the measurement result and divides it by two, recording the result as a numerical value. Simultaneously, the microcontroller 2 activates laser sensor 94, which emits a light signal that illuminates the corresponding fixed base 9. 1. The surface is reflected back to the initial position. Using the same principle, the longitudinal movement distance of the longitudinal moving plate 931 is measured, and the measurement result is transmitted to the microcontroller 2 via an electrical signal. The microcontroller 2 combines the measurement result with the numerical value to adjust the extension stroke of the electro-hydraulic push rod 92, causing the two longitudinal limiting seats 935 to stop after longitudinally pressing the steel plate. Simultaneously, the two adjacent transverse limiting plates 934 offset and limit the left and right sides of the steel plate, thereby achieving the hot stamping limiting operation of the steel plate (the upper surface height of the transverse limiting plate 934, the longitudinal limiting seat 935, and the longitudinal moving plate 931 are all lower than the upper surface height of the steel plate located at the hot stamping area, thus avoiding...). (Subsequent hot stamping of steel plates may cause interference). During the longitudinal movement of the longitudinal plate 931, the guide rod 96 and the corresponding round hole 96 slide adaptively. Through the sliding limit between the two, the radial pressure applied by the longitudinal plate 931 to the telescopic end of the electro-hydraulic actuator 92 is borne, preventing damage to the telescopic end of the electro-hydraulic actuator 92 due to radial pressure. When the steel plate model is changed, the operator rotates the locking bolt 937 so that it is connected to the corresponding slide 933 by thread, thus moving away from the corresponding insertion hole 936. The locking bolt 937 is then engaged with the insertion hole 936, which locks the slide 933. Then, the slide 933 is moved along... The slide 932 drives the corresponding transverse limiting plate 934 and longitudinal limiting seat 935 to move, thereby adjusting the transverse limiting distance of the steel plate by the two adjacent transverse limiting plates 934. The position adjustment of the transverse limiting plate 934 can be carried out with the help of an external measuring tape. Then, the locking bolt 937 is rotated in the opposite direction, and the locking bolt 937 is inserted into the corresponding insertion hole 936 through the same principle, thereby locking the slide 933. This device can automatically perform marking and hot stamping limiting operations on the steel plate through transmission and detection elements, improving the hot stamping effect of the steel plate. Moreover, the limiting components can be adjusted to a certain extent according to the changes in the size of the steel plate, making it convenient to use.

[0027] The working principle of the small metal flat hot stamping machine provided by this utility model is as follows: The size data of the steel plate is entered into the microcontroller 2. When performing hot stamping operation on the marking area of ​​the steel plate, the steel plate is first fed into the left end of the conveyor belt of the feeder 8 at equal intervals through the external feeding device. The feeding tray 18 is equipped with a roll of electroplated aluminum foil. The operator squeezes the initial end of the roll of electroplated aluminum foil from below the hot stamping plate 6 into the feeding gap between the two feeding rollers 16. Then, the microcontroller 2 starts the feeder 8. The feeder 8 runs through its own belt to perform hot stamping operation on the steel plate from left to right. At the same time, the microcontroller 2 activates the laser sensor 3 11. The laser sensor 3 11 emits a light signal to the upper edge of the front wall of the feeder 8 and reflects it back to the initial position. According to the light signal... The distance between the two is detected by measuring the propagation time and speed, and the detection result is transmitted to the microcontroller 2 as an electrical signal. When the rightmost end of the steel plate passes the position of the laser sensor 311 along with the conveyor belt of the feeder 8, the detection result of the laser sensor 311 changes. At this time, the microcontroller 2 starts timing through its internal timing unit. At the same time, the microcontroller 2 divides the transverse width of the steel plate by two to obtain the corresponding value. Then, based on this value and the material conveying speed of the feeder 8 per unit time, the microcontroller 2 controls the continued running time of the feeder 8 through its own timing unit. When the middle of the steel plate is roughly below the hot stamping plate 6 along with the conveyor belt of the feeder 8, the feeder 8 stops running. The two sets of support rods 10 support the steel plate at that position of the conveyor belt of the feeder 8. The side is supported to prevent the steel plate from being pressured and causing the belt to sink during the subsequent hot stamping process. Then, the microcontroller 2 activates the electro-hydraulic actuator 92, causing its extension end to move the corresponding longitudinal moving plate 931 synchronously towards the longitudinal center of the device. (At the initial stage of device use, the microcontroller 2 activates the laser sensor 95. The laser sensor 95 emits a light signal that illuminates the front longitudinal moving plate 931 and reflects back to the initial position. The signal emitting end of the laser sensor 95 is vertically aligned with the front side of the rear longitudinal moving plate 931. Based on the propagation speed and time of the light signal, the longitudinal distance between the two longitudinal moving plates 931 is obtained, and this result is transmitted to the microcontroller 2 as an electrical signal. The microcontroller 2 subtracts the longitudinal width of the steel plate from the measurement result and divides it by two, recording the result as a value.) At the same time, the single... Microcontroller 2 activates laser sensor 94, which emits a light signal that illuminates the surface of the corresponding fixed base 91 and reflects back to its initial position. Using the same principle, it measures the longitudinal movement distance of the longitudinal moving plate 931 and transmits the measurement result to microcontroller 2 via an electrical signal. Microcontroller 2 combines the measurement result with the numerical value to adjust the travel of the telescopic end of the electro-hydraulic push rod 92, causing the two longitudinal limiting seats 935 to stop longitudinally pressing the steel plate. Simultaneously, the two adjacent transverse limiting plates 934 offset and limit the left and right sides of the steel plate, thus achieving the hot stamping limiting operation on the steel plate (the upper surface height of the transverse limiting plate 934, the longitudinal limiting seats 935, and the longitudinal moving plate 931 are all lower than the upper surface height of the steel plate at the hot stamping area).To avoid interfering with subsequent hot stamping of the steel plate, during the longitudinal movement of the longitudinal plate 931, the guide rod 96 and the corresponding circular hole 96 slide adaptively. Through the sliding limit between the two, the radial pressure applied by the longitudinal plate 931 to the telescopic end of the electro-hydraulic push rod 92 is borne, preventing damage to the telescopic end of the electro-hydraulic push rod 92 due to radial pressure. After the hot stamping of the steel plate is limited, the microcontroller 2 starts the electro-hydraulic push rod 4, causing its telescopic end to drive the hot stamping plate 6 vertically downward through the connecting seat 5. At the same time, the microcontroller 2 starts the ceramic heating plate 7 to heat the hot stamping plate 6. After the hot stamping plate 6 moves vertically downward a certain distance, it drives the electroplated aluminum foil below it to move vertically downward and stamp onto the lower steel plate, thereby realizing the marking and hot stamping of the steel plate. During the operation, microcontroller 2 is activated and emits a light signal to illuminate the top wall of bracket 3 and reflect it back to the initial position. Using the same principle, the vertical movement distance of the hot stamping plate 6 is measured, and the measurement result is transmitted to microcontroller 2 as an electrical signal. Microcontroller 2 controls the extension and retraction stroke of the electro-hydraulic push rod 4 based on the measurement result. During the vertical movement of the hot stamping plate 6, the connecting seat 5 drives the guide rod 12 to slide adaptively along the corresponding circular hole 2, thereby improving the vertical stability of the hot stamping plate 6. After the hot stamping is completed on the steel plate surface, microcontroller 2 controls the corresponding electrical components inside the device using the same principle to move the hot stamping plate 6 upwards and reset it. Subsequently, microcontroller 2 activates the brake motor 17, causing its output shaft to drive the corresponding feeding roller 16 through the rotating shaft 15. The rotation is reversed (when the brake motor 17 is energized, the armature inside the brake motor 17 is electromagnetically attracted, making the brake disc rotatable and allowing the brake motor 17 to rotate freely; when the brake motor 17 is de-energized, the electromagnet is de-energized, and the armature is immediately pressed by the spring, causing the brake disc to press against the rear end cover of the motor, stopping the rotation; therefore, the output shaft of the brake motor 17 has a self-locking function). Through the contact friction between the upper feed roller 16 and the electroplated aluminum foil during the reverse rotation, the electroplated aluminum foil is conveyed to the right, replacing the used electroplated aluminum foil below the hot stamping plate 6. The used electroplated aluminum foil at the right end of the feed roller 16 is collected by the external waste roll. During the rightward movement of the electroplated aluminum foil, the discharge plate 18 overcomes the damping shaft through the traction force of the electroplated aluminum foil feed. The damping shaft, mainly composed of a damping device, a rotating shaft, and an adjusting mechanism, is used to discharge material during the forward rotation of the damping shaft. The damping device is fixedly connected to the front surface of the corresponding fixed seat 14. When the damping shaft rotates, the damping device applies resistance in the opposite direction of rotation through the damping material, allowing the material discharge tray 18 to stop rotating in time. At the same time, the microcontroller 2 controls the corresponding electrical components in the device to automatically replace the steel plate fixed in the limit mechanism 9 through the same principle, preparing for the next marking and hot stamping on the steel plate surface. When the steel plate model is changed, the operator rotates the locking bolt 937 so that it is connected to the corresponding slide 933 by a thread, thus moving away from the corresponding insertion hole 936. The locking bolt 937 is then engaged with the insertion hole 936, which locks the slide 933.Then, the slide block 933 is moved along the slide groove 932, causing the corresponding transverse limiting plate 934 and longitudinal limiting seat 935 to move. This adjusts the transverse limiting distance between the two adjacent transverse limiting plates 934 and the steel plate. The adjustment of the transverse limiting plate 934 can be done with the aid of an external measuring tape. Then, the locking bolt 937 is rotated in the opposite direction, and through the same principle, the locking bolt 937 engages with the corresponding insertion hole 936, thereby locking the slide block 933 in place.
