Description

Technical Field

[0001] This utility model belongs to the field of film production technology, specifically relating to a film linkage production control device for industrial hoses. Background Technology

[0002] Large-diameter rubber hoses and fabric-reinforced rubber hoses are made by winding rubber sheets onto a tire core. The rubber sheets used in the hoses are made by mixing rubber and plastic raw materials in an internal mixer. The mixed rubber compound is in strip form with a release agent on the surface. If the rubber sheets are directly calendered, the surface of the rubber sheet is not sticky, and the sheets will not stick together when wound onto the tire core, affecting the quality of the hose. Therefore, the well-mixed strip rubber compound needs to be preheated and remixed in an extruder, then pressed into sheets by a three-roll calender, cooled by cooling rollers, and wound up and laminated by a winding machine. Different types of hoses use different rubber compounds; different hose specifications have different sheet thicknesses; and the operating speeds of the extruder, three-roll calender, cooling rollers, and winding machine are also different. If the speeds of these devices are not matched, rubber accumulation or excessive tension may occur during the manufacturing process, leading to sheet breakage. Utility Model Content

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0018] See Figures 1-3An industrial hose film production control device includes an extruder, a three-roll calender, a cooling roll, and a winding and coating machine. A drive motor 1 on the extruder, controlling the extrusion volume, is connected to a PLC controller. A drive motor 2 on the three-roll calender, controlling the calendering speed, is also connected to a PLC controller. A drive motor 3 on the cooling roll, controlling its rotational speed, is connected to a PLC controller. A drive motor 4 on the winding and coating machine, controlling the rotational speed of the winding roll 4, is connected to a PLC controller. A pneumatic braking device 8 on the winding and coating machine, controlling the unwinding roll 6, is connected to a PLC controller. The unwinding roll is located to the right of the winding roll, and a guide roll 2 is located to the left of the winding roll, corresponding to the position of the cooling roll. A tension sensor 3 is located between the guide roll 2 and the winding roll 4, and the tension sensor 3 is connected to the PLC controller.

[0019] Based on the values ​​from the tension sensor, the PLC controller controls the extrusion amount of the extruder. Combining the values ​​from the tension sensor and the extrusion amount, the PLC controller adjusts the calendering speed of the three-roll calender and the rotation speed of the cooling roller. Based on the values ​​from the tension sensor, the PLC controller controls the pneumatic braking device 8 of the drive motor 4 of the winding roller and the unwinding roller 6 in the winding and coating machine.

[0020] The tension sensor 3 is a cantilever beam tension sensor, which is existing technology.

[0021] To more accurately control the rotation speed of the winding and coating machine, a meter counter 9 is installed on the upper left of the guide roller 2. The meter counter 9 is connected to a PLC controller. The PLC collects signals from the meter counter and the tension sensor, and controls the rotation speed of drive motor 1, drive motor 2, drive motor 3, drive motor 4, and the controller of the pneumatic braking device on the unwinding roller 6.

[0022] The measuring device is a non-contact measuring device, which is existing technology. It can adopt a measuring device based on non-contact laser imaging technology with patent number CN201610154344.7. Using a non-contact measuring device can not only measure the length of the film, but also prevent the film from rubbing against the measuring device and damaging the film.

[0023] Furthermore, such as Figure 2 , 3 As shown, a take-up roller 4 for taking up the release film 110 and the film 100 is rotatably mounted on the frame 1, and an unwind roller 6 for carrying the release film 110 is rotatably mounted. At least one tension roller 5 is provided between the unwind roller 6 and the take-up roller 4. The take-up roller 4 is driven to rotate by a drive motor 7. The unwind roller 6 is equipped with a pneumatic braking device 8. The controllers of the cantilever beam tension sensor 3, the meter counter 9, the drive motor 4, and the pneumatic braking device 8 are electrically connected to the PLC. The tension sensor 3 transmits the tension signal to the PLC. The PLC controls the speed of drive motor 1, drive motor 2, drive motor 3, and drive motor 4, and outputs a control signal to the controller of the pneumatic braking device 8 to adjust the tension of the isolation film on the unwinding roller 6.

[0024] The extruder was purchased from Zhoushan Yuze Rubber & Plastic Machinery Co., Ltd., and the three-roll calender and cooling rollers were purchased from Dalian Huahan Rubber & Plastic Machinery Co., Ltd.; these are existing technologies and will not be described in detail here.

[0025] Furthermore, such as Figure 2 As shown, the guide roller 2 is provided with limiting members 21 at both ends in the axial direction to abut against the two sides of the rubber sheet 100 in the width direction.

[0026] like Figure 5 , 6 As shown in Figure 7, a positioning bolt a41 is provided on the take-up roller 4 near the frame end, and a roll 10 is fitted onto it. The end of the roll 10 has an axially provided positioning groove 11 that mates with the positioning bolt. The positioning bolt a41 engages in the positioning groove 11, preventing circumferential displacement between the roll 10 and the take-up roller, thus allowing the roll 10 to rotate with the take-up roller. A positioning bolt b61 is provided on the unwind roller 6 near the frame end. The release film is wound onto another roll b. The roll b is placed on the unwind roller 6, and the positioning bolt b61 engages with the positioning groove b on the roll b, causing the roll to rotate with the unwind roller and preventing circumferential displacement between the roll b and the unwind roller. The roll b has the same structure as the roll 10.

[0027] Work process: First, the release film 110 is wound onto the take-up roller 4 via the tension roller 5, one turn. The rubber compound is extruded through an extruder, calendered into a sheet by a three-roll calender, cooled by a cooling roller, and then the sheet passes below the guide roller and above the tension sensor, where it is bonded to the release film released by the unwinding roller. It is then wound up by the take-up roller to become the finished product. The tension sensor detects the tension value of the sheet, and the meter counter detects the length value of the sheet. The tension signal is transmitted to the PLC, which sends signals to drive motors 1, 2, 3, and 4 to adjust the speed of the take-up rollers of the extruder, three-roll calender, cooling roller, and take-up and coating machine. The signal is also sent to the controller of the pneumatic brake device 8 on the unwinding roller to adjust the tension of the release film on the unwinding roller 6.

[0028] When the tension value measured by the tension sensor is 0.5-2N, the PLC controls drive motor 1, drive motor 2, drive motor 3, and drive motor 4 to maintain the current speed. When the tension is greater than 2N or less than 0.5N, the PLC controller controls the speed of drive motor 1, drive motor 2, drive motor 3, and drive motor 4 to match, so that the tension of the film is balanced and the tension of the film is kept within the set range, preventing the accumulation of adhesive or excessive tension, and the film from breaking. By controlling the speed of drive motor 1, drive motor 2, drive motor 3, and drive motor 4 and the pneumatic braking device (8) of the unwinding roller (6), the speed of the extruder, three-roll calender, cooling roller, and winding and coating machine are matched during the film production process, and the unwinding speed of the release film is matched with the winding speed of the film, preventing the accumulation of adhesive or excessive tension, the film from breaking, and the coating not being timely. In order to more accurately control the speed of the winding and coating machine, a meter counter (9) is set on the upper left of the guide roller (2). The meter counter (9) is connected to the PLC controller. The PLC collects the signals from the meter counter and the tension sensor, and controls the speed of drive motor 1, drive motor 2, drive motor 3, drive motor 4 and the controller of the pneumatic braking device on the unwinding roller (6).

[0029] The length data signal of the meter counter is input to the PLC. The PLC controls the speed of drive motor 1, drive motor 2, drive motor 3, and drive motor 4. When the film length reaches a certain value, the speed of drive motor 1, drive motor 2, drive motor 3, and drive motor 4 gradually decreases to zero.

[0030] This invention uses a tension sensor to monitor the film tension in real time. A PLC controls the rotation speed of the extruder, three-roll calender, cooling roller, and winding roller of the winding and laminating machine to adjust the film tension, preventing wrinkles, loosening, and thickness variations caused by tension changes. It also prevents material buildup, excessive tension, or film breakage. Compared to existing technologies, this invention offers higher precision and stability, allowing for real-time monitoring and adjustment of film tension.

[0031] The above description is only a preferred embodiment of the present utility model. It should be noted that those skilled in the art can make several changes and improvements without departing from the overall concept of the present utility model, and these should also be considered within the protection scope of the present utility model.
