Description

Technical Field

[0001] The invention relates to the field of protection technology, in particular to a linkage interlocking safety protection device for a hot press. Background Art

[0002] A hot press is a device used to heat and pressurize boards. It is widely used in industries such as wood processing and composite material manufacturing. The working process is usually to place the material to be processed between the upper and lower molds, and then heat and apply pressure to shape or glue the material. During the use of the hot press, since substances such as glue may accumulate on the mold, it is necessary for staff to regularly enter the hot press to perform maintenance operations such as cleaning glue. However, there is a significant risk of the hot press starting up accidentally during this process.

[0003] In order to prevent the heat press from being accidentally started during use, the existing technology adopts methods such as double-person double locks and switch locks. However, in actual applications, some front-line employees violate the operating procedures in order to save trouble, which may still cause the machine to be accidentally started.

[0004] Once the machine is started by mistake, the hot press will first have a preheating process. After the process is completed, the upper and lower molds of the hot press will gradually press down and start to close. The inner cavity of the hot press is still in a relatively safe state during the preheating time, but the preheating process is short. For the staff who are cleaning the glue inside the hot press, they may not be able to act immediately due to the distance from the exit and nervousness, so they cannot evacuate the inner cavity of the hot press in time during the preheating process.

[0005] Therefore, in order to effectively protect the lives of staff, it is extremely important to develop a more reliable and effective hot press linkage interlocking safety protection device. Summary of the invention

[0006] The purpose of the present invention is to provide a hot press linkage interlocking safety protection device to solve the problem that when the hot press in the prior art is started by mistake, its preheating start-up process time is short, and the staff who clean the glue inside may not be able to act in time due to the long distance from the exit, tension and other reasons, and it is difficult to safely evacuate the inner cavity of the hot press during the preheating start-up process, thus posing a serious threat to the life safety of the staff.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0008] The interlocking safety protection device of the hot press includes a working trolley and universal wheels, and also includes a warning transmitter connected in series with the hot press. A signal receiver and an emergency escape system are provided on the working trolley. When the signal receiver receives the signal emitted by the warning transmitter, the emergency escape system is immediately activated to drive the working trolley to evacuate the inner cavity of the hot press.

[0009] Since the height of the inner cavity of the hot press is relatively low, personnel can lie on the work cart to operate, which is convenient for working in a limited space. After the power of the hot press is disconnected, the warning transmitter is in the off state; when the hot press is accidentally started by the power supply, the warning transmitter starts working and sends a specific signal. At this time, the signal receiver located on the work cart receives the signal and immediately triggers the emergency escape system. When the emergency escape system is activated, it can quickly drive the cart to move, allowing the personnel on the cart to quickly evacuate the inner cavity of the hot press; the above setting makes full use of the escape time from the preheating stage of the hot press to the mold closing stage. The system responds quickly and does not require personnel to perform complex operations. It realizes automatic rapid response and evacuation, and improves the efficiency and success rate of escape.

[0010] Preferably, the emergency escape system includes an adjusting mechanism and a telescopic rod arranged on the lower end surface of the working lying car, an emergency wheel is fixed on the telescopic rod, and the adjusting mechanism is used to adjust the angle of the emergency wheel during the cleaning operation of the staff so that the direction of the emergency wheel is always toward the exit of the inner cavity of the hot press. When the emergency escape system is started, the telescopic rod drives the emergency wheel to move downward, so that the universal wheel is out of contact with the ground.

[0011] When cleaning the inner cavity of the hot press, the staff will constantly change the angle of the work cart, so the adjustment mechanism continues to work and constantly adjusts the angle of the emergency wheel to keep its direction facing the exit of the inner cavity of the hot press. When the hot press starts by mistake, the emergency escape system responds immediately, and the telescopic rod quickly drives the emergency wheel down. At this time, since the angle of the emergency wheel has been adjusted in advance, the universal wheel immediately breaks contact with the ground, and the work cart can be quickly and stably evacuated toward the exit of the inner cavity of the hot press under the guidance of the emergency wheel. By adjusting the angle of the emergency wheel in advance and continuously, there is no need to adjust the angle when the hot press starts by mistake, which greatly saves escape time and significantly improves evacuation efficiency. It greatly increases the chance of successful escape of personnel.

[0012] As a preferred embodiment, a mounting groove is provided on the lower end surface of the working lying vehicle, and the adjustment mechanism includes a motor and a drive shaft fixed in the mounting groove, a turntable is fixed on the drive shaft, and a telescopic rod is fixed on the turntable.

[0013] The motor drives the drive shaft to rotate, and the turntable on the drive shaft rotates accordingly, which in turn drives the telescopic rod fixed on the turntable to rotate, thereby continuously adjusting the angle of the emergency wheel so that it always faces the exit of the hot press cavity. When the hot press starts by mistake, the emergency escape system responds immediately, and the telescopic rod quickly drives the emergency wheel down. At this time, since the angle of the emergency wheel has been adjusted in advance, the universal wheel immediately breaks contact with the ground, and the operating lying car can be quickly and stably evacuated towards the exit of the hot press cavity under the guidance of the emergency wheel.

[0014] Preferably, the emergency escape system also includes a guide signal transmitter fixed at the exit of the inner cavity of the hot press, and a guide signal receiver is provided on the working carriage. The turntable can adjust the angle of the turntable according to the signal received by the guide signal receiver, so that the direction of the emergency wheel is always toward the exit of the inner cavity of the hot press.

[0015] With the help of the guide signal transmitter and receiver, the direction of the hot press cavity exit can be accurately determined, and then the angle of the emergency wheel can be accurately adjusted to ensure that no matter what position and angle the work vehicle is in, the emergency wheel can quickly and accurately point to the exit, greatly shortening the escape preparation time and significantly improving the escape efficiency.

[0016] Preferably, the emergency escape system also includes a rotating rod arranged on the lower end surface of the working lying car, a high-pressure airbag is arranged at the end of the rotating rod, and an airbag outlet is arranged on the high-pressure airbag. The rotating rod can adjust the angle of the airbag outlet according to the signal received by the guide signal receiver, so that the direction of the airbag outlet is always parallel to the outlet direction of the inner cavity of the hot press. When the emergency wheel moves downward to make the universal wheel leave the ground, the airbag outlet opens.

[0017] The addition of high-pressure airbags and adjustable airbag outlet design further improves the safety and stability of escape. The outlet direction of the airbag outlet is parallel to the inner cavity of the heat press, which can provide additional push in an emergency and help the operator to evacuate more quickly and smoothly. The rotating rod adjusts the airbag outlet angle according to the guide signal to ensure that the airbag outlet can play the best role in any situation, providing an extra layer of protection for escape.

[0018] A driving chamber is provided inside the working lying car, and a connecting groove is provided between the driving chamber and one of the mounting grooves. One end of the rotating rod extends into the driving chamber and a driven gear is fixed to the extending part. A driving gear consistent with the specifications of the driven gear is fixed on the driving shaft. A rack is provided between the driven gear and the driving gear, and the rack passes through the connecting groove to connect the driven gear and the driving gear.

[0019] The motor drives the drive shaft to rotate, and the driving gear on the drive shaft rotates accordingly. The driving gear drives the driven gear to rotate through the rack, and then the rotating rod connected to the driven gear rotates, thereby adjusting the angle of the airbag outlet on the high-pressure airbag so that it always faces the outlet of the hot press cavity. At the same time, the turntable also adjusts the angle of the emergency wheel driven by the drive shaft. The synchronous adjustment of the emergency wheel and the airbag outlet angle is achieved through the same drive source, which simplifies the system structure, reduces costs, and improves the stability and reliability of the system.

[0020] Preferably, the work lying car is provided with a safety belt for restraining the human body; it also includes a quick release buckle, which is installed at the connection position of the safety belt, and the safety belt can be released by pressing the quick release buckle.

[0021] When workers enter the hot press cavity and lie on the work cart to work, they should fasten their safety belts, which restrain the human body to prevent accidental falling during normal operation or emergency escape. When the hot press is started by mistake and the emergency escape system is activated, if there is a special situation that requires quick exit from the work cart, the workers can quickly release the safety belts by pressing the quick release buckle.

[0022] As a preference, a safety airbag is provided at the outlet of the inner cavity of the heat press, and the operating vehicle hits the safety airbag after rushing out of the inner cavity of the heat press.

[0023] The airbag can effectively cushion the impact force of the work lying car, reduce the secondary injuries to personnel that may be caused by the work lying car rushing out at high speed, and further improve the safety of the escape process.

[0024] Preferably, a protective plate is fixed on the end of the work lying car for placing the head, and a cushion is provided on the inner wall of the protective plate.

[0025] It provides special protection for the workers' heads, effectively reducing the risk of head injuries, especially in emergency situations, and can better ensure life safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Example

[0036] The hot press interlocking safety protection device includes a warning transmitter connected in series with the hot press, which has the function of monitoring the power status of the hot press in real time. Common warning transmitters are as follows:

[0037] Electromagnetic induction warning transmitter: monitors the power supply status by sensing the magnetic field changes generated by the current of the heat press power supply line. When the magnetic field changes corresponding to the starting current of the heat press are detected, a warning signal is emitted.

[0038] Voltage detection warning transmitter: directly connected to the power supply line of the heat press, when the detection voltage reaches the working threshold of the heat press, it triggers the warning signal to judge the start-up status of the heat press.

[0039] Intelligent current transformer warning transmitter: uses current transformer to monitor the current of the heat press power supply line, analyzes the current characteristics through the built-in microprocessor, and sends out a warning signal after confirming the start of the heat press. It can also identify abnormal start-up.

[0040] Wireless power monitoring module warning transmitter: obtains the real-time power parameters of the heat press through wireless communication, and sends a warning message to the signal receiver of the work carriage 110 when detecting parameter changes related to the start-up of the heat press.

[0041] Once the heat press is mistakenly started due to an accidental power supply, the warning transmitter will instantly start working and send a specific signal to the signal receiver of the operating carriage 110.

[0042] like Figure 1 and Figure 7As shown, the structure of the work lying car 110 is as follows: the work lying car 110 is specially designed to adapt to the special environment of the low height of the inner cavity space of the hot press. Its overall shape is relatively flat, and its size is precisely planned, so that the staff lying on the work lying car 110 can move flexibly in the limited inner cavity space. There are multiple universal wheels 1101 evenly distributed on the bottom of the work lying car 110. These universal wheels 1101 enable the work lying car 110 to easily change direction in the inner cavity of the hot press during normal operation, meeting the operation needs of the staff at different positions.

[0043] The relevant structure of the emergency escape system is as follows: it includes an emergency wheel 1201 and a high-pressure airbag 1502; the lower end surface of the work lying car 110 is provided with a plurality of mounting grooves 1102, and an adjustment mechanism is arranged in the mounting grooves 1102, and the adjustment mechanism is mainly composed of a motor 1301, a drive shaft 1302 and a turntable 1303. When the motor 1301 is started, the drive shaft 1302 rotates synchronously therewith, and the top of the drive shaft 1302 is fixed with a turntable 1303, and the turntable 1303 can be driven by the drive shaft 1302 to perform precise angle rotation. At the center of the turntable 1303, a telescopic rod 120 is vertically fixed, and the telescopic rod 120 is set as an electric telescopic rod 120, and the emergency wheel 1201 is fixed at its end. The rotation of the drive shaft 1302 and the turntable 1303 driven by the motor 1301 can achieve precise adjustment of the angle of the emergency wheel 1201.

[0044] The high-pressure airbag 1502 is fixed on the rotating rod 1501, and one end of the rotating rod 1501 extends into the driving chamber 1103 inside the working lying vehicle 110. The part extending into the driving chamber 1103 is firmly fixed with a driven gear 1504. A driving gear 1304 having the same specifications as the driven gear 1504 is correspondingly fixed on the driving shaft 1302. The driving gear 1304 and the driven gear 1504 are connected by a rack 190. The rack 190 passes through the connecting groove 1104 between the mounting groove 1102 and the driving chamber 1103, and the two gears are closely connected. An airbag outlet 1503 is provided on the high-pressure airbag 1502. When the rotating rod 1501 rotates under the drive of the driving shaft 1302, the angle of the airbag outlet 1503 on the high-pressure airbag 1502 can be accurately adjusted so that the direction of the airbag outlet 1503 is always parallel to the outlet direction of the inner chamber of the hot press.

[0045] At the exit of the hot press cavity, a guide signal transmitter is fixed. It is like a precise "lighthouse", continuously emitting signals of specific frequency and direction to guide the direction of the safe exit for the work trolley 110. The work trolley 110 is correspondingly equipped with a guide signal receiver, which can accurately capture the signal emitted by the guide signal transmitter and transmit the signal to the control component associated with it, so as to achieve precise adjustment of the angle of the turntable 1303, ensuring that the emergency wheel 1201 is always accurately facing the exit of the hot press cavity.

[0046] The work lying car 110 is used to place the end of the head, and a protective plate 180 is fixed thereon. A cushion is provided on the inner wall of the protective plate 180. The cushion is made of a soft material with good buffering properties, and can provide comfortable and reliable protection for the worker's head.

[0047] The work lying vehicle 110 is also equipped with a safety belt 160, which is made of high-strength material and can effectively restrain the human body to prevent the worker from falling off the work lying vehicle 110 due to accidental shaking or bumping during the work process. A quick release buckle 1601 is installed at the connection position of the safety belt 160.

[0048] The operating principle of the hot press linkage interlocking safety protection device is as follows:

[0049] When the worker is ready to enter the heat press cavity to work, he will first lie on the work lying car 110, fasten the safety belt 160, and then smoothly move the work lying car 110 to the designated position of the heat press cavity through the rolling operation of the universal wheel 1101. At this time, the heat press is in a power-off state, and the warning transmitter is in a non-working state and will not send a signal.

[0050] During the entire operation, due to the working requirements of the hot press cavity, the staff needs to constantly change the angle of the operating vehicle 110 to meet the operating requirements of different positions and directions. During this process, the guide signal receiver will continue to receive the signal from the guide signal transmitter at the outlet of the hot press cavity. After receiving the signal, the guide signal receiver will convert the signal into an electrical signal and transmit it to the circuit system of the motor 1301. After receiving the control signal, the motor 1301 starts and drives the drive shaft 1302 to rotate. The rotation of the drive shaft 1302 will drive the driving gear 1304 fixed thereon to rotate synchronously, and the driving gear 1304 will transmit power to the driven gear 1504 through close engagement with the rack 190. After obtaining power, the driven gear 1504 will drive the rotating rod 1501 connected thereto to rotate, thereby adjusting the angle of the airbag outlet 1503 on the high-pressure airbag 1502 so that it is always parallel to the outlet direction of the hot press cavity. At the same time, the rotation of the driving shaft 1302 will also drive the turntable 1303 to rotate, thereby adjusting the angles of the telescopic rod 120 and the emergency wheel 1201 fixed on the turntable 1303, ensuring that the emergency wheel 1201 also always accurately points to the exit direction of the inner cavity of the heat press.

[0051] The guidance signal transmitter and guidance signal receiver can be set as the following transmitters:

[0052] Infrared guide signal transmitter and receiver: by transmitting a specific coded infrared signal, the direction of the work carriage 110 is indicated. The principle is based on the linear propagation characteristics of infrared rays, and accurate guidance can be achieved in a relatively short distance and unobstructed environment in the heat press cavity.

[0053] Ultrasonic guide signal transmitter and receiver: continuously emit ultrasonic signals, use the propagation of ultrasonic waves in the air, and use sound wave reflection and time difference to determine the position and direction information, so as to guide the working lying car 110 to a safe exit.

[0054] Once the heat press is started by mistake due to a power failure, the warning transmitter will instantly sense the change in the power state of the heat press, start working immediately, and send a specific signal to the outside. After receiving the signal from the warning transmitter, the signal receiver on the work carriage 110 will quickly trigger the emergency escape system.

[0055] After the emergency escape system is activated, the first action performed is that the telescopic rod 120 quickly drives the emergency wheel 1201 to move downward. Under the rapid drive of the telescopic rod 120, the emergency wheel 1201 quickly descends until the universal wheel 1101 is completely out of contact with the ground. At this time, the emergency wheel 1201 assumes all the support and guidance functions of the operation lying car 110. Since in the normal operation stage, the angles of the emergency wheel 1201 and the airbag outlet 1503 have been accurately adjusted according to the guidance signal, and always maintain the exit direction toward the inner cavity of the hot press, the operation lying car 110 can be guided by the emergency wheel 1201, and evacuate quickly and stably toward the inner cavity outlet direction of the hot press.

[0056] During the evacuation of the work lying vehicle 110, when the emergency wheel 1201 moves downward to make the universal wheel 1101 off the ground, the airbag outlet 1503 on the high-pressure airbag 1502 will automatically open. The opening time of the high-pressure airbag 1502 can be calculated according to the descending distance and descending speed of the emergency wheel 1201, and it is set to open after the emergency wheel 1201 descends for a fixed time.

[0057] The high-pressure gas pre-stored inside the high-pressure airbag 1502 is quickly ejected to form a backward thrust, providing additional power support for the evacuation of the work cart 110, helping the work cart 110 to move toward the exit more quickly, and further increasing the evacuation speed.

[0058] When the work carriage 110 rushes out of the inner cavity of the hot press quickly, it will directly hit the safety airbag arranged at the exit of the inner cavity. With its good elasticity and buffering performance, the safety airbag can effectively absorb the impact force of the work carriage 110, so that the work carriage 110 can stop smoothly in a short time, avoiding serious secondary injuries to the work carriage 110 and the people in the carriage due to the high-speed rushing out.

[0059] During the entire evacuation process, if the staff encounters a special situation where they need to quickly leave the work lying car 110, such as the work lying car 110 encountering an obstacle and being unable to move forward during the evacuation process, the staff can quickly loosen the safety belt 160 by pressing the quick release buckle 1601 installed at the connection position of the safety belt 160, thereby being able to flexibly get rid of the restraint of the safety belt 160 and leave the work lying car 110 in time to further ensure their own life safety. The protective plate 180 fixed at the end of the work lying car 110 for placing the head and the soft cushion on the inner wall always provide reliable protection for the staff's head during the entire operation and escape process to prevent the head from being injured due to collision and other reasons.

[0060] Through the close cooperation between the warning transmitter and the signal receiver, when the hot press is started by mistake, the emergency escape system can be automatically triggered and started in a very short time, without the need for staff to manually operate complex escape devices. The precious escape time window from the hot press preheating stage to the mold closing stage is fully utilized, which greatly improves the efficiency and success rate of escape and provides the first solid guarantee for the life safety of staff.

[0061] The setting of the guide signal transmitter and the guide signal receiver ensures that no matter what position and angle the working lying vehicle 110 is in the inner cavity of the hot press, the emergency wheel 1201 and the airbag outlet 1503 can always be accurately parallel to the outlet direction of the inner cavity of the hot press through precise signal feedback and angle adjustment. This precise guidance mechanism effectively avoids escape delays caused by wrong direction or unclear guidance, ensures that the working lying vehicle 110 can evacuate the dangerous area at the fastest speed and in the most accurate direction, and further improves the efficiency and safety of escape.
