Description

Technical Field

[0001] This invention relates to the field of film conveying, and in particular to a casting roller mounting structure. Background Technology

[0002] During the production of films of different materials, the temperature of the casting process needs to be adjusted according to the different materials being produced, and the film is calendered to achieve film shaping. The casting process generally involves: extruding the molten film from the output of the extruder, the extruded film entering between two casting rollers, where the film is cooled and calendered by the casting rollers, and then further cooled by cooling rollers.

[0003] For example, Chinese Patent Publication No. CN104626434B discloses a high-speed casting machine and a method for producing breathable films. The casting rollers are arranged in a side-by-side manner. The film is cooled and calendered by wrapping it around the casting rollers. However, depending on the film material, the current casting method is to directly adjust the number, length, and diameter of the casting rollers to achieve different casting effects to meet the needs of processing films of different materials.

[0004] However, in existing technologies, the casting roller body is usually directly connected to the output shaft of the motor, and the motor base is generally fixed to the frame of the casting machine with screws. This means that when the position of the casting roller body needs to be adjusted, the position of the motor must be adjusted first, and then the position of the casting roller body must be adjusted. On the one hand, it is difficult to determine the installation position of the casting roller body based on the position of the motor. On the other hand, since the motor base needs to be fixed to the frame of the casting machine with screws, this adjustment method can only be carried out in a stepped adjustment manner according to the actual film material. For example, the motor is installed according to the position of the screw holes opened on the frame to achieve stepped adjustment, which makes the adjustment of the position of the casting roller body very inconvenient. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to solve at least one of the technical problems mentioned above.

[0006] The solution to the technical problem of this invention is:

[0007] A casting roller mounting structure includes a bracket, a mounting block, a motor, a sleeve, a limiting component, and a casting roller body. The mounting block is disposed on the bracket, and the casting roller body is disposed on the mounting block. The casting roller body and the mounting block are rotatable relative to each other. The sleeve is fixedly connected to the mounting block. One end of the casting roller body extends into the sleeve. The output shaft of the motor extends into the sleeve and is drively connected to the casting roller body. The limiting component connects the sleeve and the motor and is used to prevent the stator of the motor from rotating circumferentially.

[0008] As a further improvement to the above technical solution, the limiting component includes a first limiting plate and a second limiting plate. Two first limiting plates are provided, with the two first limiting plates spaced apart. The two first limiting plates are fixed on the outer casing of the motor, and the second limiting plate is disposed between the two first limiting plates.

[0009] As a further improvement to the above technical solution, the limiting component also includes two limiting bolts, which are respectively disposed on the two first limiting plates and are used to abut against the second limiting plate.

[0010] As a further improvement to the above technical solution, multiple limiting components are provided, and all the limiting components are arranged in a circular array with the output shaft of the motor as the center.

[0011] As a further improvement to the above technical solution: a coupling is provided inside the sleeve, and the coupling and the sleeve can rotate relative to each other. The output shaft of the motor is connected to the main body of the casting roller through the coupling.

[0012] As a further improvement to the above technical solution, the bracket includes a frame body, a slide rail disposed on the frame body, and a slider disposed on the slide rail. The slider and the slide rail are slidable relative to each other. The slider has a shaft hole, and the mounting block is disposed in the shaft hole. The mounting block is fixedly connected to the slider.

[0013] As a further improvement to the above technical solution, the frame body is provided with a pushing device, which drives the slider to slide along the slide rail.

[0014] As a further improvement to the above technical solution, two slide rails are provided, which are arranged facing each other. Two slots are provided on the slider, and the slide rails are inserted into the slots. The slots and the slide rails slide in a one-to-one correspondence.

[0015] As a further improvement to the above technical solution, the casting roller body and the mounting block are connected by a bearing.

[0016] As a further improvement to the above technical solution, the sleeve is provided with a number of mounting holes that penetrate the sleeve wall.

[0017] The beneficial effects of this invention are as follows: the casting roller body is mounted on the mounting block, and the casting roller body and the mounting block can slide relative to each other. The sleeve is fixedly connected to the mounting block. The output shaft of the motor and the casting roller body extend into the sleeve, and the motor drives the casting roller body to rotate. The limiting component is used to prevent the stator of the motor from rotating with the output shaft of the motor. The weight of the motor itself is directly borne by the output shaft of the motor, that is, the motor housing is not completely locked. Thus, the casting roller body can be used as a positioning reference. If the position of the casting roller body needs to be adjusted, only the position of the casting roller body needs to be adjusted directly. There is no need to consider the positioning reference of the motor, and the installation is very convenient. Attached Figure Description

Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them.

[0025] Reference Figures 1-4 A casting roller mounting structure includes a bracket 1, a mounting block 2, a motor 3, a sleeve 4, a limiting component, and a casting roller body 11. The mounting block 2 is mounted on the bracket 1, and the casting roller body 11 is mounted on the mounting block 2. The casting roller body 11 and the mounting block 2 are rotatable relative to each other. The sleeve 4 is fixedly connected to the mounting block 2, and one end of the casting roller body 11 extends into the sleeve 4. The output shaft of the motor 3 extends into the sleeve 4 and is drively connected to the casting roller body 11. The limiting component connects the sleeve 4 and the motor 3 and is used to prevent the stator of the motor 3 from rotating circumferentially.

[0026] As described above, the casting roller body 11 is mounted on the mounting block 2, and the casting roller body 11 and the mounting block 2 are relative to each other via a slider 9. The sleeve 4 is fixedly connected to the mounting block 2. The output shaft of the motor 3 and the casting roller body 11 extend into the sleeve 4, and the motor 3 drives the casting roller body 11 to rotate. The limiting component is used to prevent the stator of the motor 3 from rotating with the output shaft of the motor 3, and the weight of the motor 3 itself is directly borne by the output shaft of the motor 3, that is, the outer shell of the motor 3 is not completely locked. Thus, the casting roller body 11 can be used as a positioning reference. If the position of the casting roller body 11 needs to be adjusted, the position of the casting roller body 11 only needs to be adjusted directly, without considering the positioning reference of the motor 3, making the installation very convenient.

[0027] The limiting assembly is used to prevent the stator of motor 3 from rotating with the output shaft of motor 3. In some embodiments, the limiting assembly includes a first limiting plate 51 and a second limiting plate 52. Two first limiting plates 51 are provided, spaced apart, and fixed to the housing of motor 3. The second limiting plate 52 is disposed between the two first limiting plates 51. This structure is simple and easy to set up. The second limiting plate 52 is disposed between the two first limiting plates 51, and the first limiting plates 51 can be used to limit the first limiting plate 51, thereby effectively preventing the housing of motor 3 from rotating with the output shaft of motor 3.

[0028] In this scheme, the housing of motor 3 can be understood as part of the stator of motor 3.

[0029] To facilitate adjustment of the position of the motor 3, in some embodiments, the limiting assembly further includes two limiting bolts 53. These two limiting bolts 53 are respectively mounted on the two first limiting plates 51 and are used to abut against the second limiting plate 52. In use, a gap is left between the first limiting plate 51 and the second limiting plate 52. The limiting bolts 53 are threaded onto the first limiting plate 51. The user can adjust the distance between the second limiting plate 52 and the two first limiting plates 51 by adjusting the length of the two limiting bolts 53 extending into the second limiting plate 52. For example, the user can first adjust the relative position between the second limiting plate 52 and the two first limiting plates 51, and then make the two limiting bolts 53 abut against the second limiting plate 52. With the two limiting bolts 53 clamping the thickness of the second limiting plate 52, the circumferential movement of the second limiting plate 52 is restricted.

[0030] To ensure structural stress balance, in some embodiments, multiple limiting components are provided, and all the limiting components are arranged in a circular array with the output shaft of motor 3 as the center.

[0031] To facilitate the transmission connection between the motor 3 and the casting roller body 11, in some embodiments: a coupling 6 is provided inside the sleeve 4, and the coupling 6 and the sleeve 4 can rotate relative to each other. The output shaft of the motor 3 is connected to the casting roller body 11 through the coupling 6. This structure is simple and easy to set up.

[0032] To achieve adjustable position of the casting roller body 11, in some embodiments, the support 1 includes a frame body, a slide rail 8 mounted on the frame body, and a slider 9 mounted on the slide rail 8. The slider 9 can slide relative to the slide rail 8. The slider 9 has a shaft hole, and a mounting block 2 is disposed in the shaft hole and fixedly connected to the slider 9. With this structure, the slider 9 can slide along the slide rail 8, thereby moving the mounting block 2 along with the slider 9, achieving adjustable position of the casting roller body 11 and stepless adjustment of the position of the casting roller body 11.

[0033] To facilitate adjustment of the position of the casting roller body 11, in some embodiments, a pushing device 7 is provided on the frame body. The pushing device 7 drives the slider 9 to slide along the slide rail 8. The pushing device 7 can drive the slider 9 to slide along the slide rail 8, thereby adjusting the position of the slider 9. At the same time, the position of the slider 9 is also positioned and fixed by the pushing device 7. Optionally, the pushing device 7 is a servo electric cylinder or a servo push rod.

[0034] To ensure stable sliding of the slider 9, in some embodiments, two slide rails 8 are provided, facing each other. The slider 9 has two slots into which the slide rails 8 are inserted, with each slot corresponding to a slide rail 8 in a sliding engagement. This structure allows the two slide rails 8 to clamp the slots on the slider 9 from both sides, ensuring that the slider 9 slides along the guide rails 8.

[0035] In order to make the relative rotation between the casting roller body 11 and the mounting block 2 smoother, in some embodiments, the casting roller body 11 and the mounting block 2 are connected by bearings.

[0036] To facilitate the user's connection of the motor 3's output shaft and the casting roller body 11 via the coupling 6, in some embodiments, the sleeve 4 is provided with several mounting holes 10 penetrating the wall of the sleeve 4. Before use, the coupling 6 is first placed inside the sleeve 4. The user inserts the motor 3's output shaft and the casting roller body 11 into the coupling 6 respectively. Then, the user can tighten the screws on the coupling 6 through the mounting holes 10, so that the coupling 6 clamps the motor 3's output shaft and the casting roller body.

[0037] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
