Description

Technical Field

[0001] This utility model relates to the field of industrial equipment, and in particular to a roll material supply device and a dual-shaft drive pressure roller machine. Background Technology

[0002] refer to Figure 1 As shown, a prior art roll material supply device is used to supply roll material 20 to the processing unit inside a pressure roller mill. A power source 1, through the pivoting of its output shaft 11, drives a first mounting shaft 3 to rotate. The first mounting shaft 3 is connected to the core 201 of a roll material 20, allowing the roll material 20 to move around the central axis of the core 201. In this design, after the roll material 20 is used, the power source 1 needs to decelerate, and then another roll material 20 waiting below it is swapped with the one above it. This process inevitably results in wasted time waiting, and the deceleration process can also cause material bending, leading to defects.

[0003] refer to Figure 2 As shown, Figure 2 Another prior art roll material feeding device is shown. Compared with the above-mentioned technical solution, this solution provides a power source 1 for each roll of material 20. Although this arrangement allows for switching to another roll of material 20 after one roll is used up, it increases the number of power sources 1. Furthermore, in order to control the surface tension of the material during the feeding process of each roll of material 20, a tension control unit must be provided for each roll of material 20, which also increases the number of tension control units and thus increases the equipment manufacturing cost.

[0004] It is evident that existing roll material supply devices suffer from high manufacturing costs when using dual-axis drive. Utility Model Content

[0040] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0041] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0042] In this utility model, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0043] To address the high manufacturing cost of existing roll material feeding devices with dual-axis drive, this invention provides a roll material feeding device and a dual-axis drive pressure roller machine.

[0044] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0045] refer to Figure 3 As shown, one embodiment of this utility model provides a roll material supply device, which is compact in structure and reliable in operation.

[0046] Specifically, the device includes a power source 1, a drive shaft 2, a first mounting shaft 3, and a second mounting shaft 4. The power source 1 has a pivotable output shaft 11, which is the power core of the entire device. In this embodiment, the power source 1 is typically configured as a motor.

[0047] The output shaft 11 is connected to the drive shaft 2 via a chain drive or belt drive structure. This connection method is simple and practical, and can ensure the stable transmission of power.

[0048] Furthermore, the output shaft 11 is also connected to the first mounting shaft 3 via the first clutch mechanism 5, while the transmission shaft 2 is connected to the second mounting shaft 4 via the second clutch mechanism 6. The design of the clutch mechanism makes the transmission between the shafts more flexible, allowing for engagement or disengagement as needed to meet different operational requirements.

[0049] In this embodiment, the first mounting shaft 3 and the second mounting shaft 4 are respectively used for transmission connection with the core 201 of the roll material 20. During the rotation of the first mounting shaft 3 and the second mounting shaft 4, the roll material 20 can be driven to pivot, thereby realizing material supply.

[0050] With the above configuration, the output shaft 11 is connected to the drive shaft 2 via a chain drive or belt drive structure. The output shaft 11 is also connected to the first mounting shaft 3 via a first clutch mechanism 5, while the drive shaft 2 is connected to the second mounting shaft 4 via a second clutch mechanism 6. By driving the power source 1, dual-axis rotation of the first mounting shaft 3 and the second mounting shaft 4 can be achieved, reducing the configuration cost of the power source 1.

[0051] The output shaft 11 is driven by the first mounting shaft 3 through the first clutch mechanism 5, while the transmission shaft 2 is driven by the second mounting shaft 4 through the second clutch mechanism 6. This allows the roll material supply device to selectively use the first mounting shaft 3 to feed the roll material 20; or, use the second mounting shaft 4 to feed the roll material 20; or, simultaneously use the first mounting shaft 3 and the second mounting shaft 4 to feed the roll material 20 corresponding to each of them. In this case, the roll material 20 usually includes two different specifications of material.

[0052] The arrangement of the first clutch mechanism 5 and the second clutch mechanism 6 helps to create a certain deceleration buffer between the output shaft 11 and the first mounting shaft 3, and between the transmission shaft 2 and the second mounting shaft 4, so as to avoid material damage caused by sudden deceleration.

[0053] Furthermore, the roll material supply device in this embodiment also includes a magnetic powder brake 7, which is connected to one end of the drive shaft 2 via a coupling. The other end of the drive shaft 2 is connected to the second mounting shaft 4 via a second clutch mechanism 6. The magnetic powder brake 7 can provide stable braking force, control the rotational speed and stop of the drive shaft 2, thereby controlling the rotational speed and stop of the second mounting shaft 4, and further controlling the rotational speed and stop of the core 201 of the roll material 20 connected to the second mounting shaft 4.

[0054] Understandably, the tension of the rolled material 20 during the unwinding process can be adjusted by setting the magnetic powder brake 7.

[0055] Furthermore, the drive shaft 2 is coaxially arranged with the brake shaft 71 of the magnetic powder brake 7 to ensure smooth transmission. The coupling uses standard parts and is tightly connected between the drive shaft 2 and the brake shaft 71, transmitting torque while allowing a certain amount of axial displacement to accommodate minor adjustments during installation and operation.

[0056] Furthermore, both the first clutch mechanism 5 and the second clutch mechanism 6 are electromagnetic clutch mechanisms, which control the engagement and disengagement of the clutch through electromagnetic force to realize the power transmission and disconnection between the drive shaft and the mounting shaft. They are compact in structure, respond quickly, and control precisely.

[0057] Furthermore, the chain drive structure specifically includes components such as a gear 81, a sprocket 82, and a chain 83. The gear 81 is tightly fitted onto the output shaft 11 of the power source 1 and rotates together with the output shaft 11. The sprocket 82 is fitted onto the transmission shaft 2, serving as the other end of the transmission chain. The chain 83 is constructed into a closed ring structure, possessing good wear resistance and strength, ensuring the stability and reliability of the transmission. The chain 83 is fitted onto both the gear 81 and the sprocket 82, and meshes tightly with both.

[0058] The gear 81 drives the chain 83, which in turn drives the pivot of the transmission shaft 2, thus realizing the power transmission between the output shaft 11 and the transmission shaft 2. This structure is reasonably designed, has high transmission efficiency, and is easy to maintain and replace.

[0059] Furthermore, the roll material supply device is also equipped with a tension control unit, which is cleverly integrated into the chain drive structure or belt drive structure and electrically connected to the power source 1. As the "brain" of the system, the tension control unit is responsible for precisely controlling the start and stop of the power source 1. When it is necessary to adjust the material tension, the tension control unit sends a signal to the power source 1, prompting it to start or adjust its output power. This change is then transmitted through the output shaft 11, and the rotational speed of the first mounting shaft 3 is flexibly adjusted by the first clutch mechanism 5. Consequently, the core 201, which is closely connected to the first mounting shaft 3, rotates accordingly, thereby precisely controlling the material tension of the roll material 20 mounted on the first mounting shaft 3. Similarly, the power transmission mechanism between the output shaft 11 and the transmission shaft 2 allows the roll material supply device to adjust the rotation of the second mounting shaft 4 through the transmission shaft 2 and the second clutch mechanism 6, thereby achieving precise control of the material tension of the roll material 20 mounted on the second mounting shaft 4.

[0060] It should be noted that, due to the synchronous movement of the output shaft 11 and the transmission shaft 2, when configured as described above, the rolled material 20 mounted on the first mounting shaft 3 and the rolled material 20 mounted on the second mounting shaft 4 often have essentially the same tension. Combined with the aforementioned magnetic powder brake 7, the tension of the rolled material 20 on the second mounting shaft 4 can be further adjusted via the magnetic powder brake 7. This configuration allows for different tensions between the rolled material 20 mounted on the second mounting shaft 4 and the rolled material 20 mounted on the first mounting shaft 3, thereby meeting the different tension requirements when supplying different materials.

[0061] Furthermore, the roll material supply device is also carefully designed with two support members 9, which are arranged vertically opposite each other to provide stable support for the core 201 of the roll material 20. The two ends of the core 201 rest on these two support members 9 respectively, ensuring the stability and accuracy of the roll material 20 during unwinding. The first mounting shaft 3 is driven by the core 201 of one of the roll materials 20, responsible for driving the unwinding of that roll material. The second mounting shaft 4 is driven by the core 201 of the other roll material 20, also undertaking the task of driving the unwinding. This design allows the device to process two roll materials simultaneously, improving production efficiency and flexibility.

[0062] Preferably, the first mounting shaft 3 and the second mounting shaft 4 are designed to be parallel to each other. This layout not only ensures the uniformity and stability of the roll material 20 during the unwinding process, but also simplifies the mechanical structure, making installation, debugging and maintenance more convenient, and improving the reliability and durability of the entire roll material supply device.

[0063] Preferably, the first mounting shaft 3 and the output shaft 11 are coaxially arranged, while the second mounting shaft 4 is coaxially arranged with the transmission shaft 2. This design makes power transmission more direct and efficient, reduces energy loss during transmission, and also makes the structure of the entire roll material supply device more compact and reasonable.

[0064] Another embodiment of this utility model provides a dual-shaft drive pressure roller machine, which includes the roll material supply device as described above.

[0065] In summary, the embodiments of this utility model achieve the following technical effects:

[0066] Output shaft 11 is connected to drive shaft 2 via chain drive or belt drive to achieve power transmission. Simultaneously, output shaft 11 also engages with first mounting shaft 3 via first clutch mechanism 5, allowing power to be transmitted to first mounting shaft 3. Similarly, drive shaft 2 engages with second mounting shaft 4 via second clutch mechanism 6 to achieve power transmission. This design achieves dual-axis rotation of first mounting shaft 3 and second mounting shaft 4 by driving a single power source 1, effectively reducing the configuration cost of the power source and improving the system's economy and practicality.
