Description

Technical Field

[0001] This utility model relates to the field of calendering machine technology, and in particular to a novel calendering machine. Background Technology

[0002] In the film processing, the calender plays a crucial role. It uses pressurized and heated rollers to finish the film surface, improving its smoothness, gloss, and thickness uniformity. However, existing calenders have several problems. Firstly, cleaning the rollers after use requires complex disassembly, increasing cleaning difficulty and labor intensity, wasting considerable time, and impacting production efficiency. Secondly, traditional roller adjustment methods rely on manual mechanical operation, resulting in low precision and difficulty in accurately controlling the gap between rollers. This leads to unstable film processing quality, failing to meet the requirements for high-quality film processing. Therefore, it is necessary to improve existing calenders. Utility Model Content

[0011] Furthermore, it includes a lifting mechanism, which is disposed at the front and rear positions of the machine body.

Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "several" or "more than" means two or more, unless otherwise explicitly specified. In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances. In this application, unless otherwise expressly specified and limited, "above" or "below" a second feature can include direct contact between the first and second features, or it can include contact between the first and second features through another feature between them.

"Below," "below," and "under" of a second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0031] In view of the technical problems described in the background art, such as Figure 1-2As shown, a novel calender is provided, comprising: a machine body 1 for mounting and supporting mechanical components; a first guide roller assembly 2 mounted on the machine body 1 for guiding film material; a second guide roller assembly 3 mounted on the machine body 1, located on one side of the first guide roller assembly 2 for guiding film material; a third guide roller assembly 4 mounted on the machine body 1, disposed on the side of the second guide roller assembly 2 away from the first guide roller assembly 2 for guiding film material; a swing arm mechanism 5 mounted on the machine body 1 and connected to the first guide roller assembly 2, the swing arm mechanism 5 driving the first guide roller assembly 2 to rotate and adjust the gap between it and the second guide roller assembly 3; and an adjustment mechanism 6 mounted on the machine body 1 and connected to the third guide roller assembly 4, the adjustment mechanism 6 driving the third guide roller assembly 4 to adjust the gap between it and the second guide roller assembly 3.

[0032] This novel calender mainly consists of a machine body 1, a first guide roller assembly 2, a second guide roller assembly 3, a third guide roller assembly 4, a swing arm mechanism 5, an adjustment mechanism 6, a first blocking assembly 22, a lifting mechanism 28, and a traveling mechanism 33. The machine body 1 serves as the installation and support foundation for the entire equipment, providing a stable structural frame for other mechanical components. The guide roller assemblies cooperate to guide and finish the film material. The swing arm mechanism 5 and the adjustment mechanism 6 are used to adjust the gaps between the first guide roller assembly 2 and the third guide roller assembly 4 and the second guide roller assembly 3, respectively. The first blocking assembly 22 assists in controlling the gap between the first roller 9 and the second roller 12. The lifting mechanism 28 enables the longitudinal lifting of the machine body 1, and the traveling mechanism 33 facilitates the movement of the equipment.

[0033] In the above technical solution, the structural shape of the fuselage 1 can be adapted to the specific mechanical components, and the fuselage 1 has sufficient rigidity and stability.

[0034] The first guide roller assembly 2, the second guide roller assembly 3, and the third guide roller assembly 4 are used to guide the transport of the film material. The film material enters from the first guide roller assembly 2 and the second guide roller assembly 3, and exits from the second guide roller assembly 3 and the third guide roller assembly 4, thereby realizing the traction operation of the film material.

[0035] The swing arm mechanism 5 is mounted on the machine body 1 and connected to the first guide roller assembly 2. The function of the swing arm mechanism 5 is to drive the first guide roller assembly 2 to rotate and control the distance between the first guide roller assembly 2 and the second guide roller assembly 3, so that the first guide roller assembly 2 and the second guide roller assembly 3 can be cleaned respectively. At the same time, the swing arm structure can assist in adjusting the gap between the first guide roller assembly 2 and the second guide roller assembly 3, which helps to control the thickness of the film material.

[0036] The adjustment mechanism 6 is installed on the machine body 1 and connected to the third guide roller assembly 4. The function of the adjustment mechanism 6 is to drive the third guide roller assembly 4 to move and control the distance between the second guide roller assembly 3 and the third guide roller assembly 4, so as to perform cleaning operations on the second guide roller assembly 3 and the third guide roller assembly 4. At the same time, the adjustment mechanism 6 can assist in adjusting the gap between the third guide roller assembly 4 and the second guide roller assembly 3, which helps to control the thickness of the film material.

[0037] By adopting the above technical solution, this novel calender uses a swing arm mechanism 5 and an adjustment mechanism 6. The swing arm mechanism 5 drives the first guide roller assembly 2 away from the second guide roller assembly 3, and the adjustment mechanism 6 drives the third guide roller assembly 4 away from the second guide roller assembly 3. This facilitates the roller cleaning process, eliminates the need for complex disassembly, reduces cleaning difficulty and labor intensity, and saves cleaning time. Traditional calenders rely on manual mechanical operation for roller adjustment, resulting in low adjustment accuracy. This novel calender uses the swing arm mechanism 5 and the adjustment mechanism 6 to drive the first guide roller assembly 2 and the third guide roller assembly 4 respectively to adjust the gap with the second guide roller assembly 3, eliminating the need for manual mechanical adjustment. This allows for more precise control of the gap between the rollers, thereby better meeting the requirements of film processing for smoothness, gloss, and thickness uniformity, and improving product quality.

[0038] like Figure 3 As shown, the first guide roller assembly 2 includes a first servo motor 7, a first reducer 8 driven and connected to the first servo motor 7, and a first roller 9 connected to the first reducer; the first roller 9 is provided with a cooling pipe, which is connected to the external coolant.

[0039] The working process is as follows: After receiving the control signal, the first servo motor 7 transmits power to the first roller 9 through the first reducer 8, driving the first roller 9 to rotate. The coolant in the cooling pipe is used to quickly cool and shape the film material. The internal thread structure of the cooling pipe in the first roller 9 ensures that the surface of the film material is heated evenly, guaranteeing the quality of the film material processing.

[0040] like Figure 4As shown, the second guide roller assembly 3 includes a second servo motor 10, a second reducer connected to the second servo motor 10, and a second roller 12 connected to the second reducer 11; the second roller 12 is provided with a cooling pipe, which is connected to the coolant in the outside.

[0041] Working principle: Similar to the first guide roller assembly 2, the second servo motor 10 drives the second roller 12 to rotate, and the cooling pipe rapidly cools and shapes the film material on the second roller 12. The second guide roller assembly 3 works in conjunction with the first guide roller assembly 2 to perform preliminary guiding and finishing of the film material.

[0042] like Figure 5 As shown, the third guide roller assembly 4 includes a third servo motor 13, a third reducer connected to the third servo motor 13, and a third roller 15 connected to the third reducer 14; the third roller 15 is provided with a cooling pipe, which is connected to the external coolant.

[0043] Working principle: The third servo motor 13 drives the third roller 15 to rotate through the third reducer, and the cooling pipe rapidly cools and shapes the film material on the third roller 15. The third guide roller assembly 4 plays a role in further finishing and guiding the film material during the processing.

[0044] refer to Figure 6-7 As shown, the swing arm mechanism 5 includes a first side plate 16 mounted on the body 1, a second side plate 17 spaced apart from the first side plate 16, a first movable plate 18 mounted on the first side plate 16, a second movable plate 19 mounted on the second side plate 17, a support rod 20 disposed between the first side plate 16 and the second side plate 17, and a first telescopic member 21 disposed on the body 1; wherein, the first end of the support rod 20 is connected to the first side plate 16 and the first movable plate 18 through a sliding bearing, the second end of the support rod 20 is connected to the second side plate 17 and the second movable plate 19 through a sliding bearing, the first telescopic member 21 is respectively disposed at the positions of the first movable plate 18 and the second movable plate 19, and the telescopic ends of the first telescopic member 21 are respectively connected to the first movable plate 18 and the second movable plate 19.

[0045] Working principle: When cleaning of the first guide roller assembly 2 and the second guide roller assembly 3 is required, the first telescopic component 21 extends or retracts (the first telescopic component 21 can be a cylinder or a hydraulic cylinder), driving the first movable plate 18 and the second movable plate 19 to move. This, in turn, causes the first guide roller assembly 2 to rotate around a certain axis via the support rod 20 and the sliding bearing, opening the first guide roller assembly 2 relative to the second guide roller assembly 3, facilitating the cleaning operation of the end faces of the first roller assembly 9 and the second roller assembly 12. Furthermore, for example, the first telescopic component 21 can be a hydraulic cylinder. The extension and retraction of the hydraulic cylinder can be precisely controlled by the control system to accurately adjust the gap size, thereby adjusting the gap between the first roller assembly 9 and the second roller assembly 12, and indirectly adjusting the film thickness. To improve operational smoothness, like Figure 8 As shown, the present invention includes a first blocking assembly 22, which is respectively disposed between the ends of the first roller 9 and the second roller 12; the first blocking assembly 22 includes a first blocking block 23 installed at the end of the first roller 9 and a spiral push rod 24 installed at the end of the second roller 12; the spiral push rod 24 adjusts the gap with the first blocking block 23 to control the gap between the first roller 9 and the second roller.

[0046] In use, by rotating the spiral push rod 24, the gap between the spiral push rod 24 and the first blocking block 23 is adjusted, thereby controlling the gap between the first roller 9 and the second roller 12. When the first roller 9 is driven by the swing arm mechanism 5, the first blocking block 23 on the first roller 9 contacts the spiral push rod 24 on the second roller 12, thereby controlling the thickness of the film material.

[0047] like Figure 9 As shown, the adjustment mechanism 6 includes a second blocking block 25 installed at the end of the second roller, a second telescopic member 26 disposed on the machine body 1, and a slide rail 27 installed on the machine body 1; the telescopic end of the second telescopic member 26 is connected to the end of the third roller 15, the slide rail 27 is connected to the end of the third roller 15, the second telescopic member 26 drives the third roller 15 to move along the slide rail 27, and adjusts the gap between the third roller 15 and the second roller 12.

[0048] When adjusting the gap between the third roller 15 and the second roller 12, the second telescopic member 26 extends or retracts (the second telescopic member 26 can be a cylinder or a hydraulic cylinder), driving the third roller 15 to move along the slide rail 27, thereby changing the distance between the third roller 15 and the second roller 12, facilitating the cleaning operation of the second roller 12 and the third roller 15. By adjusting the contact between the third roller 15 and the second blocking block 25, the thickness of the film material can be controlled.

[0049] refer to Figure 10As shown, this utility model includes a lifting mechanism 28, which is disposed at the front and rear positions of the machine body 1. The lifting mechanism 28 includes a lifting motor 29, a first worm gear assembly 30 connected to the lifting motor 29, a transmission rod 31 connected to the first worm gear assembly 30, and a second worm gear assembly 32 connected to the transmission rod 31. The lifting motor 29 drives the first worm gear assembly 30 and the second worm gear assembly 32 to lift the machine body 1 longitudinally.

[0050] In practical use, different production conditions require adjustments to the height of the calender, necessitating the use of additional processing equipment.

[0051] The specific working process is as follows: After the lifting motor 29 starts, it drives the first worm gear assembly 30 to rotate, and transmits the power to the second worm gear assembly 32 through the transmission rod 31. The two worm gear assemblies work together to lift the machine body 1 longitudinally. This lifting method has a self-locking function, which can ensure the stability of the machine body 1 after lifting. For example, when it is necessary to adapt to film extruders of different heights, the height of the machine body 1 can be adjusted through the lifting mechanism 28.

[0052] refer to Figure 11 As shown, the present invention also includes a walking mechanism 33, which is disposed at the bottom of the body 1. The walking mechanism 33 includes a walking motor 34, a walking reducer 35 driven and connected to the walking motor 34, a walking gear 36 connected to the walking reducer 35, and a rack and pinion track 37 cooperating with the walking gear 36. The walking motor 34 drives the walking gear 36 to move along the rack and pinion track 37.

[0053] The specific working process is as follows: the walking motor 34 drives the walking reducer 35, the walking reducer 35 drives the walking gear 36 to rotate, the walking gear 36 meshes with the rack and pinion track 37, thereby causing the equipment to move along the rack and pinion track 37. This walking mechanism 33 can achieve precise positioning and flexible movement of the equipment, facilitating transfer between different working positions.

[0054] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
