Description

Technical Field

[0001] This application relates to the field of tire manufacturing technology, and in particular to a fixed-length cutting line for rubber sheets. Background Technology

[0002] The existing rubber products industry processes rubber sheets in various ways, such as stripping, slicing, and rolling. Slicing is particularly widespread. The working principle involves cutting the unbroken rubber sheet into sheets of the same length, which are then stacked. The existing cutting methods are mainly manual, which has low automation, poor safety, low efficiency, and high labor intensity.

[0003] Currently, in order to improve cutting efficiency, mechanical cutting is adopted, and the cutting method of upper and lower cutters is mostly used. However, during the cutting process of upper and lower cutters, the entire conveyor equipment needs to be stopped before the cutting operation can be carried out, which results in slow cutting speed, low production efficiency and easy accumulation of rubber material. Summary of the Invention

[0004] The purpose of this utility model application is to provide a film fixed-length cutting line that enables cutting without stopping the production line, ensures continuous operation of the production line, improves the degree of automation, and increases production efficiency.

[0005] This application provides a film fixed-length cutting line, which includes a continuous cutting production line for cutting film strips to a fixed length; the continuous cutting production line includes: a conveying mechanism, a feed roller mechanism disposed on the conveying mechanism, a rotary cutting device connected to the conveying mechanism, and a cut piece conveying line connected to the rotary cutting device; the continuous cutting production line also includes a control system, which, after receiving the film length information detected by the feed roller mechanism, controls the rotary cutting device to be in a first working state and a second working state.

[0006] In this application, after the metering wheel mechanism measures the quantitative length of the conveyed rubber strip, the control system receives the length information and controls the rotary cutting device to rotate and cut, thereby achieving quantitative and accurate cutting without stopping the machine, improving production efficiency while ensuring continuous operation of the production line.

[0007] In one specific implementation, when the control system controls the rotary cutting device to be in the first working state, the rotary cutting device stops to avoid the conveying of the adhesive strip; when the control system controls the rotary cutting device to be in the second working state, the rotary cutting device rotates and cuts the adhesive strip to the required length. After receiving the measurement data information from the measuring wheel mechanism, the control system controls the rotary cutting device to be in the set working state.

[0008] In one specific implementation, the conveying mechanism and the fabric piece conveying line are assembled at different heights, with the conveying mechanism higher than the fabric piece conveying line, to achieve seamless conveying.

[0009] In one specific implementation, the rotary cutting device is mounted between the misalignment gap between the conveying mechanism and the cut piece conveying line; and a guide plate with side shielding is provided between the conveying mechanism and the rotary cutting device. Through guided conveying, the cutting operation is completed during the non-stop conveying process.

[0010] In one specific implementation, the measuring wheel mechanism is mounted on one end of the conveying mechanism near the rotating cutting device. This ensures the accuracy of the measurement data by minimizing intermediate numerical differences.

[0011] In one specific implementation, the fabric feeder is mounted at an angle toward the rotary cutter device to achieve precise cutting.

[0012] In one specific implementation, the lower end of the fabric piece conveyor line is located directly below the rotary cutter device. The fabric piece conveyor line connects to the cut adhesive strips.

[0013] In one specific implementation, the rotary cutting device includes: a drive motor and a rotary cutting blade connected to the drive motor; wherein the rotary cutting blade is connected to a cutting blade stop switch. After rotating to the designated position, pressing the cutting blade stop switch controls the drive motor to stop driving. Attached Figure Description

[0018] To facilitate understanding of the film fixed-length cutting line provided in this application embodiment, its application scenario is first described. The film fixed-length cutting line provided in this application embodiment is applied in the field of tire manufacturing technology. Existing cutting methods mainly include manual cutting, which suffers from low automation, poor safety, low efficiency, and high labor intensity. Currently, to improve cutting efficiency, mechanical cutting is used, often employing an upper and lower cutting blade method. However, during the upper and lower cutting process, the entire conveyor equipment must be stopped before cutting can proceed, resulting in slow cutting speed, low production efficiency, and easy accumulation of rubber material. Therefore, the film fixed-length cutting line provided in this application embodiment enables non-stop cutting on the production line, ensuring continuous operation, improving automation, and increasing production efficiency. The film fixed-length cutting line will be described in detail below with specific examples.

[0019] refer to Figure 1 As shown, Figure 1 This application illustrates a film cutting line for fixed length cutting, which includes a continuous cutting production line for cutting film strips to fixed length. The continuous cutting production line of this application achieves continuous processes of measuring the length of the film strip and cutting the fixed-length film strips online without stopping the machine. The cutting operation is completed during the conveying process of the film strip, thereby achieving high cutting efficiency without stopping the machine, avoiding film strip accumulation, and ensuring that manual intervention is avoided. Compared with cutting devices with upper and lower cutting blades, this application uses a rotary cutting method to achieve accurate measurement and cutting without stopping the machine, ensuring a high cutting effect.

[0020] Specifically, the continuous cutting production line in this application includes a conveying mechanism 100, which is used to continuously convey the cooled rubber strips. A pressure roller 110 is provided at the initial end of the conveying mechanism 100 to ensure that the rubber strips do not shift or bulge during the conveying process. The pressure roller 110 uses a nylon wheel to press the rubber strips during the conveying process.

[0021] The conveying end of the conveying mechanism 100 is provided with a measuring wheel mechanism 200. The measuring wheel mechanism 200 is used to measure the length of the rubber strip during the conveying process. The measuring wheel mechanism 200 also uses a nylon wheel and is pressed by a spring. During the conveying process of the rubber strip, the measuring wheel mechanism 200 is driven to rotate and measure the value, so as to realize the accurate measurement of the length of the rubber strip during the conveying process.

[0022] In addition, the continuous cutting production line in this application also includes a rotary cutting device 300 connected to the conveying mechanism 100, and a piece conveying line 400 connected to the rotary cutting device 300. The rubber strips conveyed by the conveying mechanism 100 are guided by the guide rollers 310 and guide plates 320, and then fed onto the piece conveying line 400 via the rotary cutting device 300. In this application, the conveying mechanism 100 and the piece conveying line 400 are assembled with a staggered height, with the conveying mechanism 100 higher than the piece conveying line 400, achieving seamless conveying. The rotary cutting device 300 is installed between the staggered gap between the conveying mechanism 100 and the piece conveying line 400; and a guide plate 320 with side shielding is provided between the conveying mechanism 100 and the rotary cutting device 300. Through guided conveying, the cutting operation is completed during non-stop conveying. The piece conveying line 400 is installed at an incline towards the rotary cutting device 300, achieving precise material cutting. Furthermore, the lower end of the fabric piece conveyor 400 is located directly below the rotary cutter device 300. The fabric piece conveyor 400 connects to the cut adhesive strips.

[0023] Combination Figure 1 and Figure 2As shown in the diagram, in this application, the conveying mechanism 100 measures the amount of adhesive strip during the conveying process. After receiving the measurement data from the feed wheel mechanism 200, the control system controls the rotary cutting device 300 to be in a first working state and a second working state according to the cutting standard. When the control system controls the rotary cutting device 300 to be in the first working state, the rotary cutting device 300 avoids the conveying of the adhesive strip; when the control system controls the rotary cutting device 300 to be in the second working state, the rotary cutting device 300 rotates and cuts the adhesive strip to the required length. After receiving the measurement value information from the feed wheel mechanism 200, the control system controls the rotary cutting device 300 to be in the set working state. It should be specifically noted that the control system in this application, after receiving the measurement value from the feed wheel mechanism 200, controls the rotary cutting device 300 to be in the first working state and the second working state, which are techniques known to those skilled in the art and will not be elaborated upon here.

[0024] The measuring wheel mechanism 200 is mounted on one end of the conveying mechanism 100 near the rotary cutting device 300. By reducing the intermediate value difference, the accuracy of the measurement data is ensured. In this application, the measuring wheel mechanism 200 is located near the rotary cutting device 300, and by rotating to measure the transmission value of the adhesive strip, the control system receives the measured value and then controls the rotary cutting device 300 to start, thereby achieving the cutting of the adhesive strip to a fixed length. The cut adhesive strip then falls onto the cutting sheet conveyor line 400 and is transported to the adhesive strip storage device.

[0025] In the specific configuration of the rotary cutting device 300, the rotary cutting device 300 includes: a drive motor 330 and a rotary cutting blade 340 connected to the drive motor 330; wherein, the rotary cutting blade 340 is connected to a cutting blade stop switch 350. After rotating to the correct position, the drive motor 330 is stopped by pressing the cutting blade stop switch 350. Guided by the guide rollers 310 and guide plate 320, the conveying mechanism 100 transports the adhesive strip to the area below the rotary cutter 340. When the measurement value received by the control system from the feed wheel mechanism 200 does not reach the cutting value, the control system does not start the drive motor 330. At this time, the rotary cutter 340 is in a raised state to avoid the passage of the adhesive strip, allowing it to fall directly onto the cutting sheet conveyor line 400. When the measurement value of the adhesive strip transported by the feed wheel mechanism 200 plus the intermediate difference meets the cutting requirements, the control system starts the drive motor 330. The drive motor 330 drives the rotary cutter 340 to rotate and cut the adhesive strip. After the rotary cutter 340 cuts the adhesive strip, it touches the cutter stop switch 350, causing the drive motor 330 to stop driving. The rotary cutter 340 in this application is a roller-type cutter. After receiving the film length information through the control system, it controls the drive motor 330 to rotate, which drives the rotary cutter 340 to rotate. When the rotary cutter 340 rotates to the set position, it touches the cutter stop switch 350 to stop the machine and avoid the passage of the film strip.

[0026] In this application, after the metering wheel mechanism 200 measures the quantitative length of the conveyed rubber strip, the control system receives the length information and controls the rotating cutter device 300 to rotate and cut, thereby achieving quantitative and accurate cutting without stopping the machine, improving production efficiency while ensuring continuous operation of the production line.

Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
