Description

Technical Field

[0001] This utility model relates to the field of slitting machine technology, specifically a safety protection device for slitting and bundling operations. Background Technology

[0002] A slitting machine is an automated device used to cut large-size coils (such as cold-rolled stainless steel coils and metal strips) into several smaller coils. It achieves continuous slitting of coils through a combination of processes such as unwinding by material rollers, compaction by pressure rollers, and winding by take-up rollers. It is widely used in industries such as metallurgy and metal processing.

[0003] Currently, the operation control of key components such as the pressure roller and take-up roller of existing slitting machines is mostly centralized through the main control console. That is, the operator on the main control console directly controls the lifting of the pressure roller and the rotation of the take-up roller through buttons. Since the steel coil bundling process in the slitting operation requires on-site personnel to enter the equipment area for manual operation, the operator on the main control console may misoperate the pressure roller or take-up roller due to information asymmetry or inadequate confirmation. This could cause the steel strip to suddenly unravel and injure on-site personnel, or cause limbs to be caught in the equipment, threatening the personal safety of the workers. Utility Model Content

[0004] The purpose of this utility model is to provide a safety protection device for roll bundling operations to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A safety protection device for roll bundling operations includes: The frame has a material roller and a take-up roller rotatably connected at both ends by bushings and bearings. The take-up roller is rotatably connected to the output end of the gearbox by a coupling. The input end of the gearbox is rotatably connected to the geared motor by a coupling. The pressure roller is rotatably connected to the sliding seat via a bearing. The upper end face of the sliding seat is fixedly connected to the output end of the control cylinder. The control cylinder is fixedly connected to the top upper end face of the pressure roller frame. A two-position control switch is fixedly connected to the upper end face of the frame on one side of the take-up roller. The two-position control switch is electrically connected to the pressure roller control button on the main control console via a power cord.

[0006] Preferably, the frame is rotatably connected to an upper dust-adhesive roller and a lower dust-adhesive roller via bushings and bearings. The roll material is released from the feed roller, with the lower surface of the roll material passing over the top of the lower dust-adhesive roller and the upper surface of the roll material passing over the bottom of the upper dust-adhesive roller.

[0007] Preferably, a sliding seat and a control cylinder are provided in the middle of the pressure roller frame, the sliding seat is slidably connected in the slide rail, and the slide rail is fixedly connected to the pressure roller frame.

[0008] Preferably, a rack is fixedly connected to the side of the sliding seat, the rack of the left sliding seat meshes with the first gear, and the gear of the right sliding seat meshes with the second gear. The first gear is connected to the second gear through a connecting rod.

[0009] Preferably, the two-position control switch has two positions: "on" and "off". When the two-position control switch is in the "off" position, the pressure roller control signal of the main control console is cut off, and the control cylinder cannot move. When the two-position control switch is in the "on" position, the pressure roller control signal of the main control console is turned on, and the control cylinder drives the pressure roller to lift or press down.

[0010] Preferably, the surfaces of the upper and lower dust-collecting rollers have a removable adhesive dust-collecting layer.

[0011] Preferably, the geared motor and the gearbox are fixedly connected to the outside of one end of the take-up roller of the frame via a bracket.

[0012] Preferably, the pressure roller frame is fixedly connected to the upper end face of the machine frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This invention establishes a dual control mechanism by setting up a two-position control switch connected in series with the pressure roller control button on the main control console. This gives the on-site bundling operator the right to control the safety, and physically cuts off the control signal of the main control console in case of misoperation. This prevents accidents caused by the steel strip scattering and injuring or getting caught in the work due to personnel coordination errors, thereby improving the safety of the operation.

[0014] This invention features racks on the sliding seats on both sides of the pressure roller, which, together with the first gear, the second gear, and the connecting rod, form a rigid linkage structure. This ensures that the lifting speed and displacement are completely consistent when the control cylinders on both sides drive the sliding seats, thus offsetting the action deviation caused by air pressure differences or mechanical wear. This ensures that the pressure roller is always horizontal and avoids quality problems such as wrinkles and displacement of the rolled material due to uneven force.

[0015] This invention, by setting an upper dust-adhesive roller and a lower dust-adhesive roller between the frames, and the surface of the dust-adhesive roller has a removable adhesive dust-removing layer, allows the roll material to be cleaned simultaneously on the upper and lower surfaces before winding, effectively removing dust and debris, improving the surface cleanliness of the roll material, and ensuring the quality of the product after slitting.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] A slitting machine is a mechanical device used to cut large rolls of materials (such as metal strips, plastic films, paper, etc.) into several smaller rolls. It is widely used in industries such as metallurgy, packaging, and printing.

[0020] Its working principle is usually that the raw material is released by the unwinding mechanism, and after passing through the guiding, tension control and slitting processes, the material is rewound into small rolls of specified specifications by the winding mechanism.

[0021] Example 1: Please see Figures 1 to 5 This utility model provides a technical solution: A safety protection device for roll bundling operations includes: The frame 1 has a material roller 5 and a take-up roller 9 rotatably connected at both ends by bushings and bearings. The take-up roller 9 is rotatably connected to the output end of the gearbox 4 by a coupling. The input end of the gearbox 4 is rotatably connected to the geared motor 2 by a coupling. The pressure roller 8 is rotatably connected to the sliding seat 1002 via a bearing. The upper end face of the sliding seat 1002 is fixedly connected to the output end of the control cylinder 1001. The control cylinder 1001 is fixedly connected to the top upper end face of the pressure roller frame 10. A two-position control switch 11 is fixedly connected to the upper end face of the frame 1 on one side of the take-up roller 9. The two-position control switch 11 is electrically connected to the control button of the pressure roller 8 on the main control console via a power cord.

[0022] Specifically, the pressure roller frame 10 is fixedly connected to the upper end face of the frame 1.

[0023] Specifically, each of the two pressure roller frames 10 is provided with a sliding seat 1002 and a control cylinder 1001. The sliding seat 1002 is slidably connected in the slide rail 1003, and the slide rail 1003 is fixedly connected to the pressure roller frame 10.

[0024] In the existing technology, the original equipment only controls the movement of the pressure roller 8 and the drum by the control button of the pressure roller 8 on the main control panel. The operator of the main control panel may lift the pressure roller 8 in advance due to insufficient confirmation, which may cause the steel strip to scatter and injure the binding operator or cause an entanglement accident.

[0025] In this embodiment, the control button for the pressure roller 8 on the main control console forms an electrical and pneumatic control connection with the control cylinder 1001. A two-position control switch 11 is added to this control link, connected in series with the control button for the pressure roller 8 on the main control console. The bundling operator can control the pressure roller 8 manually using the two-position control switch 11, preventing injury caused by operator error on the main control console. After confirming the operation is complete, the bundling operator adjusts the two-position control switch 11, and the operator on the main control console presses the button. The main control console outputs an electrical signal, controlling compressed air to enter the cylinder, driving the piston to extend and retract to raise and lower the sliding seat 1002. When the cylinder piston pushes the sliding seat 1002 up and down along the slide rail 1003, the sliding seat 1002 causes the pressure roller 8 to contact the roll material and apply pressure (e.g., ...). Figure 5 Through a dual control mechanism, safety control is given to on-site workers, which prevents safety accidents caused by personnel miscoordination from a physical perspective.

[0026] Specifically, a rack 1004 is fixedly connected to the side of the sliding seat 1002. The rack 1004 of the left sliding seat 1002 meshes with the first gear 1005, and the gear of the right sliding seat 1002 meshes with the second gear 1007. The first gear 1005 is connected to the second gear 1007 through a connecting rod 1006.

[0027] In this embodiment, the control cylinders 1001 on the left and right sides drive the sliding seat 1002 to rise and fall. The rack 1004 of the left sliding seat 1002 meshes with the first gear 1005 to generate rotation. The first gear 1005 transmits the rotation synchronously to the second gear 1007 through the connecting rod 1006. The second gear 1007 then meshes with the rack 1004 of the right sliding seat 1002, so that the two sliding seats 1002 on both sides maintain a completely consistent lifting speed and displacement along the slide rail 1003. Through the rigid linkage structure of the gear and the connecting rod 1006, the action deviation caused by the air pressure difference or mechanical wear of the two cylinders can be offset, ensuring that the pressure roller 8 is always in a horizontal state. This avoids quality problems such as wrinkles and displacement of the roll material due to uneven force, and reduces local wear of the sliding seat 1002 and the slide rail 1003, thus extending the service life of the equipment.

[0028] Specifically, the preferred model of the control cylinder 1001 is the standard cylinder SC63×200, which has sufficient thrust to meet the pressure requirements of the pressure roller 8 on the roll material.

[0029] Specifically, the frame 1 is rotatably connected by a bushing and a bearing to an upper dust-adhesive roller 7 and a lower dust-adhesive roller 6. The roll material is released from the feed roller 5, with the lower surface of the roll material passing over the upper dust-adhesive roller 6 and the upper surface of the roll material passing over the lower dust-adhesive roller 7.

[0030] Specifically, the surfaces of the upper dust-collecting roller 7 and the lower dust-collecting roller 6 have a removable sticky dust-collecting layer. The sticky dust-collecting layer is preferably made of sticky rubber material. Sticky rubber is made by adding special sticky additives to rubber raw materials. It has both the elasticity and flexibility of rubber and strong stickiness.

[0031] In this embodiment, after the roll material is released from one side of the feed roller 5, it passes through the lower dust-adhesive roller 6 and the upper dust-adhesive roller 7 in sequence. The lower surface of the roll material is in close contact with the upper surface of the lower dust-adhesive roller 6, while the upper surface is in contact with the lower surface of the upper dust-adhesive roller 7. The dust and debris on the upper and lower surfaces of the roll material are adsorbed and cleaned respectively. After being cleaned, the roll material continues to move forward, and the lower surface passes around the upper surface of the pressure roller 8. Under the pressure of the pressure roller 8, it remains flat and is finally wound into a roll by the take-up roller 9. After being cut and bundled by the operator, it is then rolled into individual rolls.

[0032] The detachable structure of the adhesive dust removal layer and the dust-adhesive roller is a conventional method for cleaning impurities on the surface of roll materials in the prior art. The specific disassembly method and material selection have mature solutions in the existing public technology, and need not be elaborated here.

[0033] Specifically, the geared motor 2 and the gearbox 4 are fixedly connected to the outside of one end of the take-up roller 9 of the frame 1 via a bracket 3.

[0034] Specifically, the preferred model of the geared motor 2 is an RV series worm gear reducer motor 2 (such as RV063-20-0.75kW). This model is suitable for the low-speed, high-torque working requirements of the take-up roller 9 and has the characteristics of small size and low noise. The gearbox 4 is preferably a hardened tooth surface cylindrical gear reducer 4 (such as ZLY series), which can withstand the impact load during the winding process and ensure the stable speed of the take-up roller 9. It is fixed to the outside of the frame 1 with the geared motor 2 through the bracket 3.

[0035] Example 2: Please see Figure 6 This utility model provides a technical solution: The frame 1 has a material roller 5 and a take-up roller 9 rotatably connected at both ends by bushings and bearings. The take-up roller 9 is rotatably connected to the output end of the gearbox 4 by a coupling. The input end of the gearbox 4 is rotatably connected to the geared motor 2 by a coupling. The pressure roller 8 is rotatably connected to the sliding seat 1002 via a bearing. The upper end face of the sliding seat 1002 is fixedly connected to the output end of the control cylinder 1001. The control cylinder 1001 is fixedly connected to the top upper end face of the pressure roller frame 10. A two-position control switch 11 is fixedly connected to the upper end face of the frame 1 on one side of the take-up roller 9. The two-position control switch 11 is electrically connected to the control button of the pressure roller 8 on the main control console via a power cord.

[0036] Specifically, such as Figure 6 The two-position control switch 11 has two positions: "on" and "off". When the two-position control switch 11 is in the "off" position, the control signal of the pressure roller 8 of the main control console is cut off, and the control cylinder 1001 cannot move. When the two-position control switch 11 is in the "on" position, the control signal of the pressure roller 8 of the main control console is turned on, and the control cylinder 1001 drives the pressure roller 8 to lift or press down.

[0037] In this embodiment, before entering the winding roller 9 area for cutting and bundling, the bundling operator must first confirm that the two-position control switch 11 is in the "off" position to ensure that the main control console cannot drive the pressure roller 8 to move via the pressure roller 8 control button. Then, the operator enters the work area to cut the wound steel coil. During the cutting process, a safe distance must be maintained from the equipment to avoid physical contact with rotating parts. After the cutting is completed, the bundling operation is carried out. When bundling, it must be ensured that the steel strip is firmly wrapped and accurately positioned. After the operation is completed, the bundling operator must check again to ensure that everything is correct before leaving the winding roller 9 area to a safe position. Then, the two-position control switch 11 is switched to the "on" position to restore the main control console's control authority over the pressure roller 8. At the same time, the operation completion status is recorded to ensure that subsequent processes can proceed normally.

[0038] In addition to controlling the pressure roller 8, the two-position control switch 11 can also be connected in series with the control button of the take-up roller 9 on the main control console via the power cord to achieve synchronous safety control of the take-up roller 9. When the two-position control switch 11 is in the "off" position, it not only cuts off the control signal of the pressure roller 8, but also cuts off the drive control circuit of the take-up roller 9, so that the geared motor 2 and the gearbox 4 cannot drive the take-up roller 9 to rotate. This avoids the risk of steel strip being dragged or caught due to the sudden rotation of the take-up roller 9 caused by the misoperation of the main control console by the binding operator. When the switch is adjusted to the "on" position, the control signal of the take-up roller 9 is synchronously connected, and the main control console can normally control the start, stop and speed of the take-up roller 9 to ensure that the slitting and winding processes are carried out in a continuous manner. This further expands the coverage of safety protection and forms double protection from the two key action nodes of the pressure roller 8 and the take-up roller 9, comprehensively improving the safety of equipment operation when multiple people are working together.

[0039] In this embodiment, the two-position control switch 11 structure is not only applicable to the safety protection of slitting machines, but its core control logic can also be transferred to the operation scenario of slitting machines. In the process of slitting and slitting of steel coils and changing coils in the slitting machine unit, which involves the cooperation of multiple people, the two-position control switch 11 is installed near key equipment such as the cutter shaft and tension roller. By connecting the corresponding control button of the main control console in series, the slitting operator can turn off the switch before entering the danger zone to cut off the signal of the main control console, so as to avoid accidental blade injury or steel strip deviation caused by misoperation. After the operation is completed, the switch is turned on to restore remote control. Thus, in equipment such as slitting machines that also rely on the cooperation of multiple positions, the same safety protection effect as that of slitting machines is achieved, which has a wide range of equipment adaptability.

[0040] In use, the roll material is first released from the feed roller 5, passing sequentially over the upper surface of the lower dust-adhesive roller 6 and the lower surface of the upper dust-adhesive roller 7 for cleaning, and then over the upper surface of the pressure roller 8 before being wound up by the take-up roller 9. During the winding process, the operator at the main control console can drive the control cylinder 1001 through the control button of the pressure roller 8 when the two-position control switch 11 is in the "on" position, causing the sliding seat 1002 to rise and fall along the slide rail 1003, thereby driving the pressure roller 8 to apply pressure to the roll material to ensure flat winding. When slitting and bundling are required, the bundling operator first confirms that the two-position control switch 11 is in the "off" position, enters the area to complete the slitting and bundling operation, and then retreats to a safe position. The switch is then adjusted to the "on" position, the main control console is restored, and the next work cycle can begin.

[0041] All other parts of this utility model not described herein are the same as existing technology, or are known technology, or can be implemented using existing technology, and will not be described in detail here.

[0042] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
