Description

Technical Field

[0001] This application relates to the technical field of roll processing equipment, and in particular to a roll extrusion molding mechanism. Background Technology

[0002] A coil extrusion forming apparatus is a device used to form coiled materials through extrusion. It mainly includes a calendering mechanism and an edge trimming mechanism. Coiled materials are continuously rolled materials, usually steel, but also include other flat materials.

[0003] The calendering mechanism is the core component of the coil extrusion forming device, typically consisting of side plates, pressure rollers, and a rotary drive assembly. The pressure rollers are positioned between two side plates and are driven to rotate by the rotary drive assembly, thus extruding and stretching the coil material to form the desired shape and thickness; however, ensuring uniform thickness is challenging. During the calendering process, the edges of the coil material may develop protrusions or irregular shapes. The edge trimming mechanism uses cutting blades to smooth these edges, ensuring neat edges and reducing subsequent processing steps.

[0004] Regarding the aforementioned technologies, the applicant believes that there is a defect of uneven thickness. Utility Model Content

[0005] To address the aforementioned technical problems, this application provides an extrusion molding apparatus for producing rolled materials.

[0006] This application provides an extrusion molding apparatus for producing roll materials, which adopts the following technical solution:

[0007] An extrusion molding apparatus for producing rolled materials includes a frame, a drive system, a dustproof mechanism, multiple traction mechanisms, and multiple pressure roller mechanisms. The multiple pressure roller mechanisms are arranged along the feeding direction and gradually rise, allowing the multiple pressure roller mechanisms to extrude the rolled material in segments and multiple times. The drive system includes multiple electric motors. Each traction mechanism is located at the discharge port at the rear of the corresponding pressure roller mechanism. Each electric motor provides power to the corresponding pressure roller mechanism and traction mechanism. The dustproof mechanism includes multiple negative pressure vacuum cleaners. The multiple traction mechanisms, multiple pressure roller mechanisms, and multiple electric motors are all detachably connected to the frame.

[0008] By adopting the above technical solution, multiple sets of pressure roller mechanisms are arranged in a gradually rising manner along the feeding direction. The roll material is subjected to segmented and multiple compressions, gradually reducing its thickness and optimizing its internal structure. The pressing amount of each pressure roller can be adjusted independently, avoiding material stress concentration or cracking caused by excessive deformation in a single operation, and significantly improving the thickness uniformity of the roll material. Each pressure roller mechanism and traction mechanism is driven by an independent motor, eliminating the need for complex mechanical transmission chains and adapting to the speed and pressure matching requirements of different materials. The negative pressure dust collector directly extracts dust from the pressure roller area, preventing foreign objects from entering the transmission system, reducing scratches on the roller surface, and ensuring the life of the equipment. The pressure roller mechanism, traction mechanism, and motor are all detachably connected to the frame through standardized interfaces, making maintenance and adjustment more convenient.

[0009] Preferably, the pressure roller mechanism includes a pressure roller, a main roller, and a first connecting mechanism. The pressure roller and the main roller of the same group of pressure roller mechanisms form a clamping area, and the clamping area forms a clamping area to compress the roll material.

[0010] By adopting the above technical solution, the clamping roller and the main roller form a clamping zone, which improves the feeding stability, makes the pressure distribution uniform, and extends the service life of the roller surface.

[0011] Preferably, the first connecting mechanism includes a linear guide rail and a hydraulic rod. The linear guide rail is fixedly connected to the frame, the pressing roller is longitudinally slidably connected to the linear guide rail, and the pressing roller is fixedly connected to the hydraulic rod to achieve longitudinal movement away from or close to the main roller.

[0012] By adopting the above technical solutions and setting independently adjustable pressure rollers, the control of roll material thickness is more precise. The guide rail slider and hydraulic rod adopt a modular quick-release design, which shortens the replacement time and reduces maintenance costs.

[0013] Preferably, both the main roller and the pressing roller include a roller body and a roller shaft, and the main roller body is equipped with an independent temperature control system, which uses an induction heating coil.

[0014] By adopting the above technical solution, an induction heating coil is integrated on the main roll, which can realize direct heating of the material. Through the step-by-step control of the roll surface temperature, the heating uniformity is significantly improved, thereby effectively improving the thickness consistency of the roll material and reducing the risk of material breakage.

[0015] Preferably, the traction mechanism includes an active traction roller, a driven roller, and a second connecting mechanism, wherein the active traction roller, the driven roller, and the second connecting mechanism in the same group of traction mechanisms form a traction zone.

[0016] By adopting the above technical solution, the traction mechanism effectively avoids phenomena such as material stretching deformation or loosening.

[0017] Preferably, the second connection structure includes a slide rail and a pneumatic spring. The slide rail is fixedly connected to the connecting rod, the slide rail is slidably connected to the driven roller, the driven roller is fixedly connected to the pneumatic spring, and the pneumatic spring is fixedly connected to the connecting rod.

[0018] By adopting the above technical solutions, the slide rail achieves high-precision motion guidance, and the pneumatic spring can precisely adjust the pressure, reducing the pressure exerted by the driven roller on the winding and absorbing impact energy to achieve buffer protection, enabling the mechanism to complete the traction task.

[0019] Preferably, the negative pressure vacuum cleaner is detachably connected to the frame and is placed in the gap between the main roller and the pressing roller of the pressure roller mechanism.

[0020] By adopting the above technical solution, the dust suction port is directly arranged in the gap between the main roller and the pressing roller. The dust suction angle is automatically adjusted according to the roller gap position to maintain the optimal collection distance, thereby achieving efficient collection of waste debris generated by calendering and improving cleaning efficiency.

[0021] Preferably, the electric motor provides power to the pressure roller mechanism and the traction mechanism, and includes gears and couplings. Each electric motor is geared to the corresponding main roller, and the gears are keyed to the corresponding electric motor and the corresponding main roller. Each electric motor is connected to the corresponding active traction roller through a coupling.

[0022] By adopting the above technical solutions, each main roller and traction roller is equipped with a dedicated motor to achieve precise speed control. The gear connection can provide high torque transmission and precision transmission guarantee for the main roller, and the coupling is connected to the active traction roller, resulting in high transmission efficiency.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] By using a series of pressure rollers arranged in a progressively increasing manner along the feeding direction, with each main roller equipped with an independent temperature control module, the thickness uniformity of the roll material is effectively improved through a multi-stage progressive extrusion process.

[0025] A negative pressure vacuum cleaner is movably connected between the main roller and the pressure roller via a frame. The adjustable angle of the negative pressure vacuum cleaner is used to collect the waste residue and dust generated by the pressure roller mechanism during operation, ensuring the quality of the roll material and preventing the pressure roller from being damaged by the waste residue.

[0033] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0034] This application discloses an extrusion molding apparatus for producing rolled materials. (Refer to...) Figure 1 It includes a pressure roller mechanism 1, a traction mechanism 2, a dustproof mechanism 3, and a drive system 4. The drive system 4 provides power to the pressure roller mechanism 1 and the traction mechanism 2. The dustproof mechanism 3 is installed at the discharge port between the main roller 11 and the pressing roller 12 of the pressure roller mechanism 1. The roll material is pulled to the next set of pressure roller mechanisms 1 by the traction mechanism 2. The pressure roller mechanisms 1 increase in height in the discharge direction. The segmented heating and extrusion makes the thickness of the roll material more uniform.

[0035] Reference Figure 2 and Figure 3 The specific pressure roller mechanism 1 includes a main roller 11, a pressing roller 12, and a first connecting mechanism 13. The first connecting mechanism 13 includes a linear guide rail 131 and a hydraulic rod 132. The main roller 11 is rotatably connected to a connecting rod 5, which is fixedly connected to the frame 6. The pressing roller 12 is above the main roller 11 and is slidably connected to the linear guide rail 131. The linear guide rail 131 and the connecting rod 5 are fixedly connected. The hydraulic rod 132 is fixedly connected to the pressing roller 12, so that the hydraulic rod 132 can control the pressing roller 12 to move linearly away from or close to the main roller 11 along the linear guide rail, and to wind an induction heating coil 111 in the roller body of the main roller 11.

[0036] Reference Figure 4The traction mechanism 2 includes an active traction roller 21, a driven roller 22, and a second connecting mechanism 23. The active traction roller 21 is rotatably connected to the connecting rod 5, the connecting rod 5 is fixedly connected to the frame 6, the driven roller 22 is slidably connected to the slide rail 231, the slide rail 231 is fixedly connected to the connecting rod 5, and the pneumatic spring 232 is fixedly connected to the connecting rod 5.

[0037] Reference Figure 5 The drive system 4 drives the gear 42 to rotate through the motor 41. The gear 42 is keyed to rotate, which drives the main roller 11 to rotate, so that the pressure roller mechanism 1 performs the squeezing work. The active traction roller 21 is connected to the motor 41 through the coupling 43, so that the active traction roller 21 rotates and cooperates with the driven roller 22 to complete the traction work.

[0038] Reference Figure 2 and Figure 6 The dustproof mechanism 3 includes a negative pressure vacuum cleaner 31. The negative pressure vacuum cleaner 31 is movably connected to the connecting rod 5 so that the angle of the suction port of the negative pressure vacuum cleaner 31 can be adjusted. The negative pressure vacuum cleaner 31 is located on the upper part of the roller gap between the main roller 11 and the pressing roller 12 of the pressure roller mechanism 1. The connecting rod 5 is fixedly connected to the frame 6.

[0039] The working principle of the extrusion molding device for producing coil material in this application is as follows: When the material for producing coil material is fed into the pressure roller mechanism 1, the motor 41 in the drive system 4 drives the main roller 11 of the pressure roller mechanism 1 to rotate, and at the same time, the hydraulic rod 132 of the pressure roller 12 moves, so that the main roller 11 and the pressure roller 12 form a precise extrusion working gap. During this process, the induction heating coil 111 of the main roller 11 is started synchronously, and the material in the contact area is heated in real time to realize the first extrusion of the coil material. The motor 41 drives the active traction roller 21 of the traction mechanism 2 to rotate, and with the cooperation of the driven roller 22, it is pulled to the next stage pressure roller mechanism 1. According to the continuous plastic deformation theory, through the progressive extrusion of multiple sets of pressure rollers, the coil material undergoes physical deformation of thinning and density increase.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
