Description

Technical Field

[0001] This invention relates to the field of calendering technology for flammable and explosive materials, and particularly to an explosion-proof automatic calendering equipment and its usage method. Background Technology

[0002] Calendering is a processing method that uses the strong shearing force between rollers and the corresponding processing temperature to repeatedly squeeze and stretch viscous materials, ultimately turning them into thin sheet products with width and thickness. Calendering generally uses calendering machines as the main equipment.

[0003] Currently, when calendering flammable and explosive materials are being processed, their inherent flammable and explosive properties can easily lead to combustion or even explosion due to high temperatures, friction, and static electricity during the production process, threatening the safety of equipment and operators. In addition, some flammable and explosive materials may release flammable gases during the production process, threatening the safety of the entire work area.

[0004] Therefore, in view of the shortcomings of the existing technology, the present invention discloses an explosion-proof automatic calendering equipment and its usage method to solve the above problems.

[0005] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solution of the present invention and for the convenience of those skilled in the art to understand it. It should not be assumed that the above content is known to those skilled in the art simply because it has been described in the background of the present invention. Summary of the Invention

[0006] To overcome the shortcomings of the prior art, the present invention aims to disclose an explosion-proof automatic calendering equipment and its usage method. It uses an explosion-proof motor to replace manual labor, and remotely controls the calendering equipment through video monitoring, parameter detection devices and a control console. At the same time, it uses a combustible gas dilution system to prevent the content of combustible gases in the air from exceeding the standard, and adds an electrostatic elimination device to effectively prevent combustion and explosion during the processing.

[0007] This invention discloses an explosion-proof automatic calendering equipment, including a control system, a calendering host, and a combustible gas dilution system.

[0008] The control system includes a control console, an explosion-proof motor, and explosion-proof cameras. The explosion-proof motor and cameras are electrically connected to the control console. There are two or more explosion-proof cameras, which are installed on the left and right sides of the calendering machine. The explosion-proof motor replaces manual operation, and the explosion-proof cameras work in conjunction with the control console for remote control, improving the safety of operators and ensuring effective monitoring of the calendering operation.

[0009] The calendering machine includes a first feeding mechanism capable of rotation, lifting, and swinging. Above the first feeding mechanism is a pressure plate mechanism that can move up and down. In front of the first feeding mechanism is a first conveying mechanism. Above the left side of the first conveying mechanism is a first auxiliary wheel that can be adjusted up and down. To the left of the auxiliary wheel is a calendering roller mechanism. On both sides of the calendering roller mechanism are static elimination mechanisms and thickness measuring mechanisms. The thickness measuring mechanism is electrically connected to the control console. The outside of the thickness measuring mechanism is covered with an explosion-proof shell. To the left of the calendering roller mechanism is a second conveying mechanism. Above the right side of the second conveying mechanism is a second auxiliary wheel that can be adjusted up and down. To the left of the second conveying mechanism is a second feeding mechanism that can swing. The first feeding mechanism, pressure plate mechanism, first conveying mechanism, calendering roller mechanism, second conveying mechanism, and second feeding mechanism are all driven by explosion-proof motors. The automatic processing and transfer of raw materials is achieved through the cooperation of multiple conveying mechanisms. At the same time, the processing accuracy is controlled by the thickness measuring device, and the generation of electrostatic sparks is avoided by the static elimination mechanism.

[0010] The combustible gas dilution system includes an air supply system, an exhaust system, and a combustible gas concentration detection device. The air supply system includes an air compressor and an air nozzle connected in sequence. The exhaust system includes a ventilation hood located above the calendering roller mechanism. An explosion-proof exhaust fan is installed at the ventilation opening of the ventilation hood. Both the air compressor and the combustible gas concentration detection device are electrically connected to the control console to reduce the concentration of combustible gas and prevent combustion and explosion.

[0011] Preferred technical solution: The first feeding mechanism includes a first conveyor belt, a rotating device, a first swinging device and a first lifting device connected in sequence. The first conveyor belt is arranged opposite to the pressure plate mechanism, which replaces manual feeding and material feeding operations, and realizes the function of receiving material sheets and switching the calendering direction.

[0012] Preferred technical solution: Both the first conveying mechanism and the second conveying mechanism are provided with limiting baffles in the width direction. The limiting baffles are provided with air blowing holes and air inlets. The air inlets are connected to air nozzles. The limiting baffles are connected to the second conveying mechanism through a spiral fine-tuning rod. The width of the sheet during the calendering process is controlled by the limiting baffles.

[0013] Preferred technical solution: The calendering roller mechanism includes an upper moving roller, a lower fixed roller, and a feed width adjustment mechanism arranged vertically from top to bottom. Both the upper moving roller and the lower fixed roller are driven to rotate by an explosion-proof motor. The feed width adjustment mechanism consists of an upper baffle, a lower baffle, a wedge block, and a cylinder. The upper baffle and the lower baffle are respectively attached to the upper and lower sides of the wedge block. The wedge block is connected to the output end of the cylinder. The upper baffle and the upper moving roller rise and fall synchronously, while the lower baffle and the lower fixed roller maintain a constant relative position. There are two sets of feed width adjustment mechanisms, and the distance between the two sets of feed width adjustment mechanisms is adjusted by a micrometer. A second lifting device is provided on both sides of the upper moving roller. The second lifting device is driven by an explosion-proof motor and adjusts the feed width of the material sheet through the feed width adjustment mechanism, while preventing the material sheet from entering the friction area and generating local high temperature.

[0014] Preferred technical solution: The static elimination mechanism adopts a carbon fiber electrostatic brush with the same width as the first feeding mechanism. Two sets of carbon fiber electrostatic brushes are provided on each side of the calendering roller mechanism. The two sets of carbon fiber electrostatic brushes on the same side are installed side by side on the upper and lower sides of the material conveying area. The static electricity of the material sheet during the processing is discharged in time through the static elimination mechanism to avoid sparks that may cause combustion and explosion.

[0015] Preferred technical solution: The thickness measuring mechanism is a laser thickness gauge. Two sets of laser thickness gauges are provided on each side of the calendering roller mechanism. The two sets of laser thickness gauges on the same side are symmetrically set on the upper and lower sides of the material conveying area and the installation distance is fixed to monitor the change of material thickness in real time.

[0016] Preferred technical solution: The second receiving and feeding mechanism includes a receiving tray, and a second swing device is provided at the bottom of the receiving tray so that the collected material pieces can be stacked together evenly.

[0017] Preferred technical solution: The air compressor and the air nozzle are connected by air ducts. The combustible gas concentration detection device is a combustible gas sensor with an explosion-proof rating of ExdⅡCT6. Air nozzles are installed on the outer periphery of the calender and at the calender roller mechanism to monitor changes in combustible gas concentration in real time and to quickly dilute combustible gas by compressing gas.

[0018] Preferred technical solution: Explosion-proof automatic calendering equipment is set up in the operation room, screw charging room and power room respectively. The screw charging room is an explosion-proof workshop. The control console is located in the operation room. The explosion-proof motor, explosion-proof camera, calendering host, gas nozzle, exhaust system and combustible gas concentration detection device are all located in the screw charging room. The air compressor is located in the power room.

[0019] This invention discloses a method for using an explosion-proof automatic calendering equipment. The method, implemented using the aforementioned explosion-proof automatic calendering equipment, includes the following steps: S1, activate the control system, calendering main unit and combustible gas dilution system; S2, place the raw material clumps onto the first feeding mechanism of the equipment to ensure that the material is completely within the transport range of the first feeding mechanism, which facilitates subsequent transportation and processing positioning; S3 uses a pressure plate mechanism to flatten the raw material clump, control the initial thickness, and facilitate subsequent processing; S4, the parameters of each calendering operation of the first conveyor mechanism, the calendering roller mechanism and the second conveyor mechanism are set through the control console, and the number of calendering operations is set. The processing is automatically controlled by the set parameters. S5, the first conveying mechanism and the second conveying mechanism switch between forward and reverse motion and combine the first auxiliary wheel and the second auxiliary wheel to realize the reciprocating feeding of the calendering roller mechanism, while ensuring that the raw material remains connected to the first auxiliary wheel or the second auxiliary wheel when leaving the calendering roller mechanism during repeated calendering. S6, according to step S5, the raw material sheet is longitudinally thinned. When the length of the raw material sheet is greater than the first conveying mechanism and the second conveying mechanism, the first receiving and feeding mechanism and the second receiving and feeding mechanism alternately fold and collect the sheet at the left and right ends respectively. When switching between forward and reverse motion, the raw material sheet is pulled into the calendering roller mechanism by the feeding end of the raw material sheet in conjunction with the first auxiliary wheel or the second auxiliary wheel to complete the longitudinal calendering. S7. After the last longitudinal cycle of calendering, the first receiving and feeding mechanism rotates 90 degrees to receive the material. All the raw material sheets are collected on the first receiving and feeding mechanism. Then, the pressure plate mechanism is used to compact the folded material to form a material pile, eliminating the folding arc and air gap. The first receiving and feeding mechanism rotates 90 degrees again to send the above material pile to the first conveying mechanism. Calendering is performed again according to step S5. S8. Set or retrieve the fine calendering parameters, and repeat steps S5 and S6 to perform transverse calendering until the sheet reaches the fine calendering parameter standard. If the sheet has toothed edges or surface defects, repeat steps S5, S6 and S7 until the sheet with the required parameters is obtained. S9: Shutdown, product inspection, product collection, and equipment cleaning.

[0020] Due to the application of the above technical solution, the beneficial effects of this invention are as follows: (1) Explosion-proof motors are used to replace manual labor and multiple size control mechanisms are used for automated production and processing, reducing the threat to personnel and equipment safety during production; (2) Using cameras and detection devices in conjunction with the control console to remotely control the calendering equipment, ensuring the safety of operators while promptly identifying production problems; (3) Add a flammable gas dilution system and an electrostatic elimination device to prevent combustion and explosion during the production process.

The first receiving and feeding mechanism rotates 90 degrees again to send the above material pile to the first conveying mechanism, and the calendering action is performed again according to step S5. S8. Set or retrieve the fine calendering parameters, and repeat steps S5 and S6 to perform transverse calendering until the sheet reaches the fine calendering parameter standard. If the sheet has toothed edges or surface defects, repeat steps S5, S6 and S7 until the sheet with the required parameters is obtained. S9: Shutdown, product inspection, product collection, and equipment cleaning.
