Description

Technical Field

[0001] The invention belongs to the technical field of pencil production, and in particular relates to an automatic hot stamping device for pencil production. Background Art

[0002] As a common writing and drawing tool, pencils are mainly composed of graphite core and wooden outer covering. In order to improve the appearance of pencils, the surface of pencils is usually hot-stamped with the help of hot-stamping devices.

[0003] At present, traditional hot stamping equipment has obvious limitations when hot stamping pencils. First, from the perspective of hot stamping efficiency, traditional hot stamping equipment can only perform hot stamping operations on a single pencil at a time, which means that the number of pencils that can be hot stamped in a unit of time is extremely limited, which greatly limits the improvement of production efficiency. Secondly, from the perspective of the operating process, during the entire hot stamping process, the pencils to be hot stamped need to be placed manually. Specifically, after completing the hot stamping of a pencil, the operator must manually place the next pencil under the hot stamping head to prepare for the next hot stamping operation. This manual placement method not only increases the workload of the operator, but also makes the entire hot stamping process more time-consuming and laborious because each placement takes a certain amount of time.

[0004] Therefore, we propose an automated hot stamping equipment for pencil production to solve the above problems. Summary of the invention

[0016] Compared with the existing technology, the advantages of an automated hot stamping equipment for pencil production are:

[0017] 1. Improve hot stamping efficiency

[0018] Hot stamping of multiple pencils at the same time: The equipment is equipped with multiple hot stamping heads, and each hot stamping operation can complete the hot stamping of multiple pencils at one time. Compared with traditional hot stamping equipment that can only perform hot stamping operations on a single pencil at a time, it greatly increases the number of pencils that can complete hot stamping in a unit time and significantly improves production efficiency.

[0019] 2. Highly automated operation

[0020] 1. Automatic material change for hot stamping rolls:

[0021] After the hot stamping is completed, when the pressure plate moves back to squeeze the first press trigger switch, the first time relay starts and controls the reduction motor to rotate for a certain period of time. The roller on the right, driven by the reduction motor, rolls up the used extension surface of the hot stamping roll. At the same time, the roller on the left cooperates to release the new extension surface of the hot stamping roll to prepare for the next batch of pencil hot stamping. The whole process does not require human intervention and is automatic and efficient.

[0022] 2. Automatic pencil change:

[0023] After the second time relay is started, it controls the servo motor to rotate for a certain period of time. The servo motor controls the two lead screws to rotate synchronously through the transmission of the worm and two worm wheels, so that the slide plate pushes the corresponding push plate up a certain distance through each push rod, and the next batch of pencils to be stamped are automatically pushed out. At the same time, the pencils after stamping are also pushed out of the open pen storage slot, which is convenient for the staff to take. This automatic material replacement method avoids the tediousness of traditional manual placement of the next batch of pencils, greatly improving work efficiency.

[0024] 3. Automatic temperature control ensures hot stamping quality

[0025] Precise temperature control mechanism: By setting a thermistor in the temperature sensing cavity of the hot stamping head, the heat conduction of the heat conducting rod is used to sense the temperature of the electric heating plate. When the temperature of the electric heating plate is too high, the resistance of the thermistor will automatically decrease, causing the electromagnetic relay to automatically disconnect and stop the electric heating plate from continuing to heat up. This automatic temperature control method can avoid the impact of excessive temperature on the hot stamping effect, ensuring that each hot stamping operation can be carried out at an appropriate temperature, thereby ensuring the stability and consistency of the hot stamping quality.

[0026] 4. Easy to operate

[0027] 1. Sealing plate design: The sealing plate set on the hot stamping table can block the discharge port of each open pen storage slot after the pencil is placed, ensuring that the pencil will not pop out accidentally during the hot stamping process. The plug-in block on the sealing plate and the slot on the hot stamping table cooperate with each other to facilitate the removal of the sealing plate. At the same time, the permanent magnet block in the slot attracts the plug-in block to ensure the stability of the sealing plate insertion and simple and convenient operation.

[0028] 2. Guide roller assistance: The guide rollers rotating on the two fixed frames fit the stretching surface of the hot stamping roll, which can assist the stretching surface of the hot stamping roll to move, avoid deviation during the material change process, reduce the operator's adjustment of the hot stamping roll, make the operation simpler and faster, ensure the stable supply of hot stamping rolls, and improve the operation stability of the equipment.

[0029] 5. Safe and reliable

[0030] 1. Buffer protection: The fixed seat is fixedly connected to the hot stamping head through multiple buffer springs. When the hot stamping head contacts the pencil, the buffer spring can use its own deformation to avoid hard squeezing of the hot stamping head and the pencil, thereby preventing damage to the pencil. At the same time, multiple limit rods fixed on the hot stamping head are slidably connected to the fixed seat, which can prevent the hot stamping head from shaking during work and ensure the accuracy of the hot stamping position.

[0031] 2. Prompt function: A second push-trigger switch is fixedly set on the upper inner wall of the driving chamber. When the slide moves up to the limit point so that all the stored pencils are pushed out, the slide will automatically press and trigger the second push-trigger switch, so that the prompter starts automatically and emits a prompt sound to remind the staff to re-prepare materials, avoiding idling of the equipment or failure due to lack of materials, thereby improving the safety and reliability of the equipment.

After the first electric cylinder 3 drives the pressing plate 4 to move up and back to its position, the pressing plate 4 will squeeze the first press trigger switch 203, so that the first press trigger switch 203 generates an electrical signal to be fed back to the PLC controller 28, so that the PLC controller 28 controls the first time relay 201 and the second time relay 202 to start, and the first time relay 201 will control the reduction motor 12 to rotate for a certain time, such as 5 seconds, so that the right winding roller 11 can roll up the stretched surface of the hot stamping roll 13 after use, and the left winding roller 11 will cooperate with the winding of the right winding roller 11 to release the new stretched surface of the hot stamping roll 13, so as to be used for the hot stamping of the next batch of pencils;

[0052] The second time relay 202 will control the servo motor 194 to rotate for a certain time, such as 2 seconds. The servo motor 194 will control the two lead screws 191 to rotate synchronously under the transmission cooperation of the worm 193 and the two worm wheels 192, so that the slide plate 17 will push the corresponding push plate 15 to move up a certain distance through each push rod 18, so that the next batch of pencils to be stamped will be automatically pushed out, avoiding the tediousness of manually placing the next batch of pencils, and the pencils after stamping can be pushed out of the open pen storage slot 14 under the push of the push plate 15 for the staff to take, and such a reciprocating cycle can realize the automatic stamping of multiple pencils, and the pencil material can be automatically replaced during the stamping process, which greatly improves the stamping efficiency and saves manpower.
