Description

Technical Field

[0001] The utility model relates to the technical field of plate processing machinery, in particular to a calender. Background Art

[0002] The calender is a commonly used sheet metal processing equipment, which usually includes several heated calendering rollers. The blank moves between the calendering rollers. The heating of the calendering rollers completes the processing of the blank and the processing of the sheet metal.

[0003] The calender's structure varies depending on the material being processed and the processing techniques. For example, for materials requiring lamination, the calender unit requires a laminating assembly; for materials requiring repeated heating, the number of calender rollers is appropriately increased; and for materials requiring both cooling and heating, cooling and heating mechanisms are configured. However, all of these calenders share a commonality: the arrangement and placement of the calender rollers, which results in the stock moving in an S-curve pattern between them. This dictates the heating requirements of the material, but it also impacts processing efficiency.

[0004] Prior art also utilizes rollers to assist in conveying blanks, eliminating the need for the blanks to travel in an S-curve. However, these prior art structures convey the blanks by driving rollers to rotate. This requires numerous rollers on a single conveyor track, each of which must be driven individually, impacting blank conveying stability. Utility Model Content

[0053] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0054] It should be noted that when an element is referred to as being “disposed on” or “connected to” another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being “connected to” another element, it can be directly connected to the other element or indirectly connected to the other element.

[0055] It should be understood that the terms "upper", "lower", "bottom", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0056] The terms "first" and "second" are used for descriptive purposes only and are not intended to imply relative importance.

[0057] refer to Figures 1 to 4 The calender includes a frame 1 and a calendering roller assembly mounted on the frame. The calendering roller assembly includes a plurality of calendering roller assembly groups spaced apart from each other. Each calendering roller assembly is defined based on its location and function. The number of calendering rollers in each calendering roller assembly may be one or two, and in some embodiments, may be more.

[0058] A conveying structure is provided in the gap between at least two adjacent calendering roll sets. For calendering machines with multiple calendering roll sets, a conveying structure may be provided between any two adjacent calendering roll sets, or between some of the calendering roll sets. For example, the choice of whether to provide a conveying structure can be determined based on the spacing between the calendering roll sets. If the gap between the calendering roll sets is large, a conveying structure may be provided; if the gap is small, no conveying structure may be provided.

[0059] The specific implementation form of the transmission structure includes a roller group, a drive motor, a transmission belt, etc.

[0060] Each roller group includes several rollers 2, which are arranged between two adjacent calendering roller groups; according to the requirements of the conveying direction and in order to match the position difference between the calendering roller groups, the rollers 2 in the roller group can be arranged horizontally or at a certain inclination.

[0061] The drive motor 3 is mounted on the frame 1 and includes a power output shaft connected to the drive wheel 13. Rotation of the power output shaft drives the drive wheel 13. A transmission belt 4 is provided around each of the rollers 2 in the roller assembly and the drive wheel 13. When the drive motor 3 is activated, the power output shaft rotates, driving the drive wheel 13, which in turn drives the transmission belt 4, conveying the sheet material blank. Once the sheet material blank passes through the first calendering roller assembly and moves onto the idler assembly, the transmission belt 4 drives it to the next calendering roller assembly.

[0062] It should be understood that if the length of the roller 2 is too long, a whole conveyor belt 4 can be used, or the conveyor belt 4 can be designed as a segmented structure. Since the same drive motor is used to drive the conveyor belt 4, the synchronous movement of multiple segmented conveyor belts 4 can be ensured. However, the preferred method is to use a whole conveyor belt.

[0063] The installation position of the drive motor affects the direction of the conveyor belt 4. In some embodiments, guide wheels are required to adjust the direction of the conveyor belt 4. The conveyor structure further includes guide wheels; these wheels are mounted on the frame 1, between the idlers 2 and the drive wheel 13. The drive belt 4 wraps around each idler 3 in the roller assembly, is guided by the guide wheels, and is wound around the drive wheel 13.

[0064] It should be understood that the number and position of the guide wheels are designed according to needs. In some embodiments of the present invention, the drive motor 3 is located below the roller group. In this case, the conveyor belt 4 needs to pass through the gap between the two calendering roller groups, which easily causes friction interference between the conveyor belt 4 and the calendering rollers. Based on this, the guide wheels include a first guide wheel 501 and a second guide wheel 502. The first guide wheel 501 and the second guide wheel 502 are arranged in the gap between two adjacent calendering roller groups, and the transmission belt 4 passes through the opposite side of the two guide wheels, that is, one side of the transmission belt 4 passes through the inner side of the first guide wheel 501, and the other side passes through the inner side of the second guide wheel 502. Refer to the attached Figure 3 and Figure 6 After the conveyor belt 4 passes through the roller group, the guide wheel and the driving wheel 13, the overall shape of the conveyor belt 4 is an inverted triangle.

[0065] refer to Figures 5 to 8 In some embodiments of the present invention, the roller assembly further includes a roller mounting block 6 provided on the frame, and the protruding shafts 201 at both ends of each roller 2 are mounted on the roller mounting block 6 .

[0066] Two implementation structures of the roller mounting block 6 are provided below.

[0067] The first implementation structure.

[0068] The roller mounting block includes an upwardly disposed slot 601 , and the extended shafts 201 at both ends of each roller 2 are located in the slot 601 .

[0069] In order to adjust the height of the roller 2, in some embodiments of the present invention, a bolt hole is provided in the slot 601, and an adjusting bolt 7 is installed in the bolt hole. The end of the adjusting bolt 7 supports the extended shaft 201 of the roller.

[0070] When the position of roller 2 needs to be adjusted,

[0071] It should be understood that the number of roller mounting blocks 6 corresponds to the number of rollers 2, that is, each roller 2 is mounted correspondingly to one roller mounting block 6. Each roller mounting block has a slot 601 structure.

[0072] In some embodiments, the roller mounting block 6 may be designed as a whole, and a plurality of slots 601 may be opened on the roller mounting block 6 to also realize the installation and adjustment functions of the roller 2 .

[0073] The second implementation structure.

[0074] An oblong hole is provided on the roller mounting block 6 along the height direction, and the extended shafts 201 at both ends of each roller 2 are located in the oblong hole.

[0075] Correspondingly, the oblong hole is provided with a bolt hole, in which an adjusting bolt 7 is installed, and the end of the adjusting bolt 7 supports the extended shaft 201 of the roller. The principle is the same as that of the slot structure, and will not be repeated here.

[0076] Taking into account the gravity of the sheet material and to ensure smooth movement of the sheet material between the various calendering roller groups, in some embodiments of the present invention, the heights of the rollers in the same roller group are sequentially lowered along the material conveying direction. For example, the height of each adjacent roller 2 is sequentially lowered by 5 cm.

[0077] The utility model also provides a specific implementation structure of a calender, which is a five-roller calender.

[0078] The calender comprises a first calendering roller group, a second calendering roller group and a third calendering roller group, wherein the second calendering roller group is located between the first calendering roller group and the third calendering roller group;

[0079] The first calendering roller group includes two calendering rollers arranged in pairs, defined as a first calendering roller 801 and a second calendering roller 802;

[0080] The second calendering roller set includes a calendering roller, defined as the third calendering roller 803;

[0081] The third calendering roller group includes three calendering rollers arranged in pairs, which are defined as a fourth calendering roller 804 and a fifth calendering roller 805 .

[0082] In some embodiments of the present invention, a transmission structure is provided between the first calendering roller group and the second calendering roller group, and between the second calendering roller group and the third calendering roller group.

[0083] Considering the heating requirements of the sheet material, some embodiments of the present invention further include a baking device 9 mounted on the frame, located above the second calendering roller set. Since both the first and third calendering roller sets include two calendering rollers, the sheet material can be heated by the temperature between the calendering rollers. However, since the second calendering roller set includes only one calendering roller, the baking device 9 located above the third calendering roller 803 ensures uniform heating on both sides of the sheet material.

[0084] The baking device 9 can be an oven, the overall length of which is equivalent to the length of the calendering roller, which can cover the entire width of the blank to ensure uniform heating. The baking device 9 is equipped with an elevator 11, wherein the elevator 11 is installed on the frame 1. Activating the elevator 11 can adjust the distance between the oven and the blank and adjust the heating effect.

[0085] Since the oven is long as a whole, two elevators 11 can be designed at both ends in the length direction, and the two elevators 11 are connected by a connecting rod 12 to ensure synchronous movement.

[0086] In some embodiments of the present invention, the entire frame 1 can be installed on the ground walking rails 9 to facilitate adjustment of the overall position of the calender.

[0087] This calender can be used for sheet production, especially for PET sheet production and can be configured in a PET sheet production line.

[0088] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
