Description

Technical Field

[0001] This invention belongs to the technical field of conveyor belt slitting equipment, and specifically relates to a fully automatic multi-bandwidth synchronous slitting equipment for conveyor belts and its correction method. Background Technology

[0002] In the conveyor belt processing industry, conveyor belt production typically follows the industry practice of "wide-width forming and on-demand slitting." This means that wide rolls are first produced according to the maximum processing capacity of the production equipment. Then, based on the actual application needs of downstream users (such as the differentiated bandwidth requirements of different scenarios like mining, logistics, and food processing), the wide conveyor belts are slitted into various narrow-width conveyor belts of different specifications before final product delivery. Therefore, longitudinal slitting, as a crucial downstream process in conveyor belt processing, directly determines product quality, production costs, and market competitiveness. The misalignment of the conveyor belt during the slitting process is the core bottleneck affecting slitting accuracy.

[0003] Currently, the conveyor belt slitting equipment widely used in the industry, whether traditional manual slitting equipment or some semi-automatic slitting equipment, all suffer from poor deviation correction capabilities during the slitting process. This problem directly leads to insufficient slitting accuracy, seriously affecting product quality and production efficiency.

[0004] Specifically, during the entire process of unwinding, traction, and slitting, the conveyor belt is prone to axial deviation due to various factors: First, the unwound material itself may have problems such as irregular winding or edge deviation, resulting in a deviation in the initial position of the conveyor belt when it is released; second, during the traction process, uneven traction tension and fluctuations in traction speed can cause the conveyor belt to deviate during transmission; third, insufficient flatness of the slitting workbench and tension differences in the conveyor belt material itself can also exacerbate the conveyor belt deviation.

[0005] Therefore, the core shortcoming of existing conveyor belt slitting equipment is its poor correction capability. It cannot solve the problem of conveyor belt deviation in real time and accurately throughout the slitting process, resulting in low slitting accuracy, unstable product quality, and high production costs, which cannot meet the needs of the modern conveyor belt processing industry for precise and efficient slitting. Summary of the Invention

[0006] The purpose of this invention is to provide a fully automatic conveyor belt multi-bandwidth synchronous slitting device and its correction method to solve the offset problem of existing conveyor belt slitting devices during the entire slitting process.

[0007] To solve the above technical problems, the present invention provides a fully automatic conveyor belt multi-bandwidth synchronous slitting device, including a slitting worktable, wherein one end of the slitting worktable is provided with an unwinding device for placing the unwound material before slitting; and the other end is provided with a winding device for placing the winding material after slitting.

[0008] The slitting table is equipped with a clamping and traction device at one end near the winding device. The clamping and traction device is used to transport the conveyor belt from the unwound material through the slitting table to the winding material.

[0009] A slitting mechanism is provided above the slitting workbench, which slits the conveyor belt into rolls of at least two widths.

[0010] A deviation correction device is also provided on one side of the slitting workbench to position the conveyor belt moving on the slitting workbench.

[0011] Preferably, the correction device includes a fixed limiting baffle, a movable limiting baffle, and a correction motor;

[0012] The fixed limiting baffle and the movable limiting baffle are arranged parallel to each other on the slitting worktable and extend along the conveying direction of the conveyor belt;

[0013] The correction motor is connected to the movable limit baffle via a ball screw pair, which drives the movable limit baffle to move closer to or away from the fixed limit baffle, thereby correcting the conveyor belt during the conveying process on the slitting workbench.

[0014] Preferably, the correction motor is installed on the side wall or back of the slitting table, and the ball screw pair spans the slitting table in the width direction, so that the movable limiting baffle can move horizontally across the entire table surface of the slitting table.

[0015] At least one correction groove is provided on the slitting worktable. The nut of the ball screw pair passes through the correction groove and is connected to the movable limit baffle, thereby driving the movable limit baffle to move horizontally.

[0016] Preferably, a grooved photoelectric sensor is symmetrically installed on the fixed limiting baffle and the movable limiting baffle near the unwinding end of the coil. The grooved photoelectric sensor detects the offset when the conveyor belt enters the slitting table.

[0017] A length encoder is also installed above the slitting workbench to measure the length of the processed conveyor belt.

[0018] Preferably, the unwinding device includes a fixed base and a sliding base, and two unwinding rollers are arranged parallel to each other on the sliding base, and the unwinding material is placed on the two unwinding rollers and rolled unwinding.

[0019] An electric push rod is installed on the fixed base. When the grooved photoelectric sensor detects that the offset of the conveyor belt edge exceeds the set tolerance, the electric push rod drives the sliding base and the unwinding material above it to move horizontally to correct the deviation.

[0020] Preferably, the clamping and traction device includes a clamping frame, in which upper pressure rollers and lower pressure rollers are distributed vertically.

[0021] The two ends of the lower pressure roller are rotatably connected to the clamping frame via bearings, and one end is equipped with a traction motor, which drives the lower pressure roller to rotate under the action of the traction motor.

[0022] The upper and lower pressure rollers are equipped with gear transmission pairs at their ends, which enable the upper and lower pressure rollers to rotate in opposite directions.

[0023] Preferably, the upper pressure roller is movably connected to the clamping frame through bearing seats with slide rails at both ends, and is equipped with a worm gear screw lifting mechanism. Under the action of the clamping motor, the worm gear screw lifting mechanism drives the upper pressure roller to approach the lower pressure roller and clamps the conveyor belt between the two.

[0024] Preferably, the slitting mechanism includes multiple sets of slitting blades, and the multiple sets of slitting blades are slidably mounted on a linear guide rail;

[0025] The slitting tool includes a tool holder, a tool clip, a blade, and a cylinder; the tool clip is mounted on the tool holder to hold the blade, and the cylinder drives the tool holder and the blade to move vertically up and down.

[0026] It also includes a servo motor, on the output shaft of which a gear is mounted, and the servo motor drives the slitting cutter to move laterally along the rack.

[0027] A pressure rod is provided at one end of the slitting workbench near the slitting mechanism. Pressure rod cylinders are provided at both ends of the pressure rod. Under the action of the pressure rod cylinders, the pressure rod is driven to press the conveyor belt on the slitting workbench, thereby ensuring the flatness of the conveyor belt before slitting.

[0028] Preferably, the winding device includes two winding rollers arranged in parallel and spaced apart. The ends of the two winding rollers are connected to the winding motor through a chain drive pair. Under the action of the winding motor, the material to be wound is placed on the two winding rollers and rolled and wound.

[0029] A roll limiter is also installed on any one of the take-up rolls to restrict the axial movement of the take-up material.

[0030] The present invention also provides a method for correcting the belt alignment of a fully automatic conveyor belt multi-bandwidth synchronous slitting device, comprising the following steps:

[0031] When the slotted photoelectric sensors at the ends of the fixed and movable limit baffles detect that the offset of the conveyor belt when entering the slitting table exceeds the set tolerance, the correction motor drives the movable limit baffle to move closer to or further away from the fixed limit baffle through the ball screw pair, thereby adjusting the offset of the conveyor belt after entering the slitting table; at the same time, the electric push rod drives the sliding seat and the unwinding material above it to move horizontally, thereby adjusting the offset of the conveyor belt before entering the slitting table, and finally achieving the correction.

[0032] In summary, the beneficial effects of the above-described technical solutions conceived by this invention compared with the prior art include:

[0033] 1. This invention incorporates a comprehensive correction device, constructing a dual automatic correction system at both the unwinding end and the worktable end. This fundamentally solves the problem of poor correction capability in existing equipment. On one hand, through slotted photoelectric sensors at the ends of the fixed and movable limit baffles, the offset of the conveyor belt entering the slitting worktable is detected in real time and with high precision. When the offset exceeds the set tolerance, the correction motor drives the movable limit baffle to move horizontally via a ball screw pair, quickly adjusting the offset of the conveyor belt after entering the worktable and ensuring that the conveyor belt is in the correct position in the slitting area. On the other hand, the unwinding device drives the sliding seat and unwinding material to move horizontally via an electric push rod, synchronously adjusting the initial offset of the conveyor belt before entering the worktable, preventing the offset at the unwinding end from being transmitted to the slitting area. This dual correction structure is responsive and precise, capable of correcting the axial offset of the conveyor belt in real time throughout the unwinding, traction, and slitting process. It effectively avoids quality defects such as uneven edges, slanted cuts, and burrs, significantly improving slitting accuracy and ensuring that the slitting conveyor belt meets user specifications, reducing rework rates and raw material losses.

[0034] 2. The slitting mechanism of the present invention is equipped with multiple slitting cutters, which are slidably mounted on linear guide rails and moved laterally along the rack by a servo motor. The spacing between the multiple slitting cutters can be adjusted precisely and quickly to adapt to the slitting requirements of different bandwidths. At the same time, the multiple slitting cutters can work synchronously, which can slit a wide conveyor belt into at least two different bandwidth rolls in one go, eliminating the need for batch processing and greatly improving production efficiency.

[0054] Example

[0055] This invention provides a fully automatic conveyor belt multi-bandwidth synchronous cutting device. Please refer to [link / reference]. Figure 1-3It includes a slitting workbench 1, one end of which is provided with an unwinding device 2 for placing the unwound material 100 before slitting; the other end is provided with a winding device 3 for placing the winding material 200 after slitting; a clamping and traction device 4 is provided at the end of the slitting workbench 1 near the winding device 3, through which the conveyor belt 300 is conveyed from the unwound material 100 through the slitting workbench 1 towards the winding material 200; a slitting mechanism 5 is provided above the slitting workbench 1, through which the conveyor belt 300 is slitted into rolls of at least two widths; a correction device 6 is also provided on one side of the slitting workbench 1 to position the conveyor belt 300 moving on the slitting workbench 1.

[0056] The overall structure of this invention is rationally laid out, with reliable connections and smooth cooperation between all components. Each component can be flexibly adjusted according to actual production needs, adapting to the slitting requirements of conveyor belts of different materials, thicknesses, and widths, demonstrating strong versatility. Furthermore, the equipment's user interface is simple and easy to understand, allowing operators to quickly learn and use it without specialized training, further improving production efficiency.

[0057] For details, please refer to Figure 4-6 The correction device 6 includes a fixed limiting baffle 601, a movable limiting baffle 602, and a correction motor 603. The fixed limiting baffle 601 and the movable limiting baffle 602 are arranged parallel to each other on the slitting table 1 and extend along the conveying direction of the conveyor belt 300. The correction motor 603 is connected to the movable limiting baffle 602 through a ball screw pair to drive the movable limiting baffle 602 to move closer to or away from the fixed limiting baffle 601, thereby correcting the conveyor belt 300 during the conveying process on the slitting table 1.

[0058] Furthermore, the correction motor 603 is installed on the side wall or back of the slitting table 1, and the ball screw pair spans the slitting table 1 in the width direction, so that the movable limiting baffle 602 can move horizontally across the entire table surface of the slitting table 1; at least one correction groove 101 is provided on the slitting table 1, and the nut pair at the end of the ball screw pair passes through the correction groove 101 and connects to the movable limiting baffle 602, thereby driving the movable limiting baffle 602 to move horizontally.

[0059] In this embodiment, a grooved photoelectric sensor 7 is symmetrically installed on one end of the fixed limiting baffle 601 and the movable limiting baffle 602 near the unwinding material 100. The grooved photoelectric sensor 7 detects the offset of the conveyor belt 300 when it enters the slitting table 1.

[0060] Furthermore, a length encoder 8 is installed above the slitting workbench 1 to measure the length of the processed conveyor belt 300.

[0061] For details, please refer to Figure 7 and Figure 8 The unwinding device 2 includes a fixed base 201 and a sliding base 202. Two unwinding rollers 203 are arranged parallel to each other on the sliding base 202, and the unwinding material 100 is placed on the two unwinding rollers 203 and rolled unwinds. An electric push rod 204 is installed on the fixed base 201. When the grooved photoelectric sensor 7 detects that the belt edge offset of the conveyor belt 300 exceeds the set tolerance, the electric push rod 204 drives the sliding base 202 and the unwinding material 100 above it to move horizontally to correct the deviation.

[0062] This invention constructs a dual automatic deviation correction system at both the unwinding end and the worktable end, fundamentally solving the problem of poor deviation correction capability in existing equipment: On the one hand, through the slotted photoelectric sensors at the ends of the fixed limit baffle and the movable limit baffle, the offset of the conveyor belt when entering the slitting worktable is detected in real time and accurately. When the offset exceeds the set tolerance, the deviation correction motor drives the movable limit baffle to move horizontally through the ball screw pair, quickly adjusting the offset of the conveyor belt after entering the worktable, ensuring that the conveyor belt is in the correct position in the slitting area; on the other hand, the unwinding device drives the sliding seat and the unwinding material to move horizontally through the electric push rod, synchronously adjusting the initial offset of the conveyor belt before entering the worktable, preventing the offset at the unwinding end from being transmitted to the slitting area.

[0063] For details, please refer to Figure 9-11 The clamping and traction device 4 includes a clamping frame 401, within which an upper pressure roller 402 and a lower pressure roller 403 are vertically distributed. The lower pressure roller 403 is rotatably connected to the clamping frame 401 at both ends via bearings, and one end is equipped with a traction motor 404, which drives the lower pressure roller 403 to rotate. Gear transmission pairs 405 are provided at the ends of the upper pressure roller 402 and the lower pressure roller 403, enabling the upper pressure roller 402 and the lower pressure roller 403 to rotate in opposite directions.

[0064] Furthermore, the upper pressure roller 402 is movably connected to the clamping frame 401 through bearing seats 406 with slide rails at both ends. It is also equipped with a worm gear screw lifting mechanism 407. Under the action of the clamping motor 408, the worm gear screw lifting mechanism 407 drives the upper pressure roller 402 to approach the lower pressure roller 403 and clamps the conveyor belt 300 between the two.

[0065] The clamping and traction device 4 of this invention adopts a structure in which upper and lower pressure rollers rotate in opposite directions. The lower pressure roller 403 is driven by a traction motor 404, and the upper pressure roller 402 can be precisely adjusted in distance from the lower pressure roller 403 via a worm gear screw lifting mechanism 407. This allows for flexible adjustment of the clamping force according to the material and thickness of the conveyor belt, avoiding slippage and offset caused by excessively loose clamping, as well as wear and deformation of the conveyor belt caused by excessively tight clamping. Simultaneously, the upper pressure roller 402 and the lower pressure roller 403 achieve synchronous opposite rotation through a gear transmission pair 405, ensuring the stability and consistency of the traction speed, preventing conveyor belt offset caused by unstable traction, and assisting in improving the correction effect and cutting accuracy.

[0066] For details, please refer to Figure 12-13 The slitting mechanism 5 includes multiple sets of slitting cutters 501, and the multiple sets of slitting cutters 501 are slidably mounted on the linear guide rail 502; each slitting cutter 501 includes a cutter holder 5011, a cutter clamp 5012, a blade 5013, and a cylinder 5014; the cutter clamp 5012 is mounted on the cutter holder 5011 to hold the blade 5013, and under the action of the cylinder 5014, it drives the cutter holder 5011 and the blade 5013 to move vertically up and down.

[0067] Furthermore, the slitting mechanism 5 also includes a servo motor 5015, on the output shaft of which a gear is mounted. Under the action of the servo motor 5015, the slitting cutter 501 is driven to move laterally along the rack 503.

[0068] In this embodiment, a pressure rod 9 is provided at one end of the slitting workbench 1 near the slitting mechanism 5, and pressure rod cylinders 10 are provided at both ends of the pressure rod 9. Under the action of the pressure rod cylinders 10, the pressure rod 9 is driven to press the conveyor belt 300 on the slitting workbench 1, thereby ensuring the flatness of the conveyor belt 300 before slitting.

[0069] For details, please refer to Figure 14 The winding device 3 includes two winding rollers 301 arranged in parallel and spaced apart. The ends of the two winding rollers 301 are connected to the winding motor 303 through a chain drive pair 302. Under the action of the winding motor 303, the winding material 200 is placed on the two winding rollers 301 and rolled and wound. A roll limiting disc 304 is also installed on either of the winding rollers 301 to limit the axial movement of the winding material 200.

[0070] This invention also provides a method for correcting the deviation of a fully automatic conveyor belt multi-bandwidth synchronous slitting device. When the slotted photoelectric sensor 7 at the end of the fixed limit baffle 601 and the movable limit baffle 602 detects that the deviation of the conveyor belt 300 when entering the slitting table 1 exceeds the set tolerance, the correction motor 603 drives the movable limit baffle 602 to move closer to or further away from the fixed limit baffle 601 through the ball screw pair, thereby adjusting the deviation of the conveyor belt 300 after entering the slitting table 1; at the same time, the electric push rod 204 drives the sliding seat 202 and the unwinding material 100 above it to move horizontally, thereby adjusting the deviation of the conveyor belt 300 before entering the slitting table 1, and finally achieving the correction.

[0071] This invention effectively solves the core defect of poor correction capability of existing slitting equipment through a dual automatic correction structure. At the same time, it takes into account many advantages and realizes high efficiency, precision, automation and multi-specification of conveyor belt slitting. It has significant practical value and can provide strong support for conveyor belt processing enterprises to reduce production costs, improve product quality and enhance market competitiveness.

[0072] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

A method for correcting the belt alignment in a fully automatic multi-bandwidth synchronous slitting device for conveyor belts, characterized in that, Includes the following steps: When the slotted photoelectric sensor (7) at the end of the fixed limit baffle (601) and the movable limit baffle (602) detects that the offset of the conveyor belt (300) when entering the slitting table (1) exceeds the set tolerance, the correction motor (603) drives the movable limit baffle (602) to move closer to or further away from the fixed limit baffle (601) through the ball screw pair, thereby adjusting the offset of the conveyor belt (300) after entering the slitting table (1); at the same time, the electric push rod (204) drives the sliding seat (202) and the unwinding material (100) above it to move horizontally, thereby adjusting the offset of the conveyor belt (300) before entering the slitting table (1), and finally realizing the correction.
