First, the fabric is manually rubbed with glue on a calender, and then the rubbed fabric is placed in a hot oven for two-stage vulcanization. The current process mainly relies on manual work.

[0003] According to the existing process flow of fabric glue vulcanization, the three-roll calender used is an "I"-shaped structure, and the glue placement position and the fabric feeding position are distributed on both sides of the equipment. At least two people are required to operate on both sides of the equipment. The final glue-wiping cloth is short due to human factors and needs to be cut continuously. The glue-wiping fabric is manually laid flat on the grate of the oven for two-stage vulcanization.

[0043] Specifically, Figure 5 As shown, the unwinding device 1 is fixed to the side of the three-roll calender 2 by bolts, and the unwinding device 1 includes a decoupling shaft 11, a magnetic powder brake 12 and a base 13. The base 13 is a flange-type safety chuck, which is fixed on the three-roll calender 2. The magnetic powder brake 12 is fixed on the base 13. In this embodiment, the magnetic powder brake is a prior art, and the model is YSB-5. One end of the decoupling shaft 11 is connected to the magnetic powder brake 12, and the other end is located on the base 13. A cloth roll with a maximum size of φ300 mm can be placed on the decoupling shaft 11. The magnetic powder brake 12 is used for tension adjustment to maintain tension when the cloth roll is decoupling to ensure that the fabric remains flat during transportation.

[0044] like Figure 3-Figure 5 As shown, the three-roll calender 2 is an "F" type structure, which is used to achieve single-sided gluing of fabrics. The "F" type structure can achieve single-person one-way operation. The three-roll calender 2 includes a No. 1 roller 21, a No. 2 roller 22, a No. 3 roller 23, a calender frame 24, four calender motors 25, a base 26 and a rubber baffle 27, and also includes a roller temperature adjustment mechanism 28, a left speed ratio gear set 29, a right speed ratio gear set 210, a reducer 211, a coupling 212, a transmission base 213, an electric motor 214, a kick switch 215, a cloth expansion roller 216, a gear reduction box 217, a main motor 218 and a rotary joint 219. The calender frame 24 is arranged on the base 26, and the No. 1 roller 21, the No. 2 roller 22 and the No. 3 roller 23 are arranged in the calender frame 24 from top to bottom. The rubber baffle 27 is located between the No. 1 roller and the No. 2 roller to control the width of the calendered film. Four chutes are provided on the inner wall of 24, and the cross-section of the chutes is rectangular. The chutes correspond to the two ends of the No. 1 roller 21 and the No. 3 roller 23 respectively. Four calendering motors 25 are respectively located on the left and right sides of the No. 1 roller 21 and the No. 3 roller 23, and respectively control the gaps between the left and right sides of the rollers. The calendering motors 25 can make the rollers of the No. 1 roller 21 and the No. 3 roller 23 move up and down in the chutes on the inner wall of the calendering frame 24 to achieve the purpose of adjusting the roller gap. It can be single-acting or linked. The calendering motor 25 is connected to a high-precision displacement sensor and a display instrument. The displacement sensor is installed between the No. 1 roller 21 and the No. 3 roller 23. The display instrument is located on the PLC. The displacement sensor and the display instrument are connected. The position of the roller is transmitted to the display instrument through the displacement sensor and observed through the touch screen. In addition, emergency stop buttons 220 at the extreme positions are provided at both ends of adjacent rollers for roller gap safety protection.

[0045] In this embodiment, the diameters of rollers 21, 22 and 23 are 250 mm, the lengths are 762 mm, the spacing between rollers is 0-10 mm, the linear speed of the rollers is 0.5-5 m / min, the speed ratio is 1:1.23:1.23, the power of the main motor 218 is 11 KW, and the speed ratio of the reducer 211 is 112.

[0046] Pass the fabric between roller No. 22 and roller No. 3, 23, and manually hang it on the needle plate of the needle plate chain transmission device 4. Adjust the equipment line speed to keep the fabric in a flat and stretched state. Place the whole piece of rubber between roller No. 1, 21 and roller No. 2, 22, adjust the roller distance between roller No. 1, 21 and roller No. 2, 22 and the rubber baffles 27 on both sides, press the rubber into a film of a certain width and thickness, and rub the film onto the fabric between roller No. 2, 22 and roller No. 3, 23 using the roller speed ratio difference.

[0047] like Figure 2 As shown, the needle plate chain transmission device 4 is used to ensure that the fabric is stable and wrinkle-free during the vulcanization molding and conveying process, including a vertical guide rail assembly, a chain assembly, an automatic needle feeding mechanism 3, an auxiliary needle feeding mechanism 11, a needle removal wheel, an edge detection mechanism 8, an inlet support frame 9 and an outlet support frame 10. The vertical guide rail assembly is arranged throughout the hot drying tunnel 5, and the two ends of the vertical guide rail assembly are respectively arranged on the inlet support frame 9 and the outlet support frame 10, the chain assembly is arranged on the vertical guide rail assembly, and the automatic needle feeding mechanism 3 and the edge detection mechanism 8 are respectively arranged on the vertical guide rail assembly. On the upper and lower sides of the mouth end, in this embodiment, the edge detection mechanism 8 is an electric eye. The fabric after glue rubbing is pressed into the needle plate by an active brush and is accurately positioned by the edge detection mechanism 8. The edge detection mechanism 8 automatically adjusts the width of the needle plate on the needle seat chain according to the width of the fabric to ensure that the fabric remains stable and wrinkle-free during operation. The auxiliary needle-loading mechanism 11 is arranged on one side of the automatic needle-loading mechanism 3, and the needle-removing wheel is arranged at the end of the vertical guide rail assembly. The vertical guide rail assembly is the moving carrier of the chain assembly, and the chain assembly is the moving and clamping carrier of the fabric or the object to be dried.

[0048] The vertical guide rail assembly includes a head guide rail, a head transition guide rail, an intermediate guide rail, a tail transition guide rail, a tail guide rail and a main sprocket which are connected horizontally in sequence. The head guide rail, the head transition guide rail, the intermediate guide rail, the tail transition guide rail and the tail guide rail are connected to form an integral guide rail. The head guide rail and the tail guide rail are respectively arranged on an inlet support frame 9 and an outlet support frame 10. The head transition guide rail, the intermediate guide rail and the tail transition guide rail are respectively arranged on a guide rail support crossbeam 12. The main sprocket is connected to the tail guide rail. Next, the head guide rail includes a passive sprocket and a cylinder. The chain assembly is tensioned by the cylinder before operation. The cylinder tensioning pressure adjustment range is: 0.3-0.45MPa (in actual operation, it is necessary to make appropriate adjustments according to the total length of the chain assembly and the temperature in the hot drying tunnel 5). The tail guide rail and the chain main drive are driven by the motor through the cycloid and pulley secondary reduction and then through the spline shaft to drive the main sprocket to rotate, and then drive the chain assembly to rotate in a directional manner (that is, the chain assembly moves from the head to the tail).

[0049] The chain assembly includes a needle seat chain and a needle plate. The needle plate is arranged on the vertical guide rail assembly, and the needle seat chain is arranged on the needle plate. In this embodiment, the needle seat chain is a vertical tank chain structure, and the needle seat chain pitch is 63.5mm. The needle seat chain serves as a running and clamping carrier for the fabric to transmit and run up and down, and the main sprocket drives the needle seat chain to run.

[0050] The automatic needle feeding mechanism 3 includes a cloth supporting plate 31, an active brush, a lower supporting wheel, a passive brush and a needle valve type oil cup. A needle removing wheel is installed on the tail guide rail. Before the fabric enters the head of the machine and is pressed into the needle plate by the active brush, it needs to pass through the cloth guide roller under the condition of a certain tension controlled by the front facilities, and be close to the cloth supporting plate. Under the precise positioning of the edge detection mechanism 8, the brush cloth pressing wheel and the brush wheel are pressed into the needle plate of the running chain in the guide rail for transportation and transmission. When it comes out at the tail of the machine, the needle removing wheel assists the cloth to be removed from the needle for winding.

[0051] The needle seat chain runs in the guide rail and is wound at the tail of the machine. Due to the characteristics of the guide rail and chain materials, in order to avoid aggravated wear of the guide rail chain, it is necessary to continuously add oil during operation. Since the present embodiment is a vertical guide rail, the lubricating oil in the track groove will leak, so an oil pan is added at the guide rail connection to collect the dripping oil through the oil pan for centralized treatment to avoid dirt on the equipment and the ground.

[0052] like Figure 6 As shown, the hot drying tunnel 5 includes three sections of insulation boxes, two doors, a cooling mechanism 51, an air supply mechanism and a heating mechanism. The two doors are located on both sides of the three sections of insulation boxes for insulation and maintenance. The air supply mechanism and the heating mechanism are fixed to the top outer wall of the insulation box. In this embodiment, the air supply mechanism is an air conditioner. The three sections of insulation boxes are horizontally fixedly connected in sequence. The insulation box is a rectangular parallelepiped. The cooling mechanism 51 is fixed to the rear section of the insulation box. In this embodiment, the cooling mechanism 51 is a negative pressure fan. The fabric after glue-rubbing enters the hot drying tunnel 5 through the needle plate chain transmission device 4. The air supply mechanism radiates hot air evenly on the surface of the fabric, vulcanizes the glue-rubbing fabric, and finally cools the vulcanized fabric through the cooling mechanism 51.

[0053] The automatic winding device 6 is used to wind up the vulcanized fabric. The automatic winding device 6 includes a winding motor, a winding frame, a cloth winding roller and an air expansion shaft 61. The winding method is passive winding. When the speed of the cloth winding roller is consistent with the speed of the needle plate chain transmission device 4, winding can be achieved. The winding motor is arranged on the outside of the winding frame. The automatic winding device 6 is also provided with a pad cloth station, which can combine the pad cloth and the wiped fabric for winding to prevent product adhesion, thereby ensuring product quality. Two brackets are fixed in parallel on the inner wall of the winding frame. In this embodiment, the automatic winding device 6 is also provided with a spare air expansion shaft 62, which can be quickly replaced. The air expansion shaft 61 and the spare air expansion shaft 62 are respectively installed on two brackets, and a meter is also installed in the automatic winding device 6.

[0054] The electrical control system 7 is located on the right side of the three-roll calender 2, and is used to realize the automation of the entire production line of this embodiment, as well as to control and detect the speed of each mechanism component. The electrical control system 7 includes an electrical control cabinet, a touch screen, a PLC (Programmable Logic Controller) and control software. The control software is loaded into the PLC, the PLC is set in the electrical control cabinet, and the touch screen is set on the electrical control cabinet. In this embodiment, the electrical control system 7 is the existing technology.

[0055] This embodiment is also provided with a run button, a stop button and a safety protection device 9. The safety protection device 9 includes three safety emergency stop buttons and an over-temperature protection mechanism. The three safety emergency stop buttons are respectively arranged at the head and tail of the needle plate chain transmission device 4 of the processing machine and the middle of the hot drying tunnel 5. Emergency braking can be performed when an unexpected failure occurs in the equipment. The over-temperature protection mechanism is arranged on the heating mechanism of the hot drying tunnel 5. In this embodiment, the over-temperature protection mechanism is a heating switch. When the temperature of the hot drying tunnel 5 exceeds the set protection temperature, the heating switch is automatically disconnected to prevent fire. The run button and the stop button are both arranged on the electric control cabinet. The run button is used to start the equipment with one button, and the stop button is used to shut down the operation of the equipment with one button. The run button, the stop button, the safety emergency stop button and the heating switch are respectively electrically connected to the electrical control system 7.

[0056] In this embodiment, the fixed connections between the components are all bolt connections.
