Description

TECHNICAL FIELD

[0001] The utility model relates to a calendering technical field, concretely is a kind of matt art paper calendering device. BACKGROUND

[0002] Matt art paper is widely used in high-end printing field, especially in the printing product with higher quality requirement of figure and text. Because its surface is relatively smooth and has lower gloss, matt art paper often needs to be treated by calendering after printing to improve its surface quality and enhance printing effect. However, traditional calendering technology often has some technical problems, which limits its application in production line with high precision and high quality requirement.

[0003] Traditional calendering device usually adopts roll calendering system, that is, the surface of paper is treated by calendering through the contact between roller and paper surface by mechanical pressure. Although this method has achieved certain success in some applications, it has the following significant problems:

[0004] Uneven calendering effect: in traditional roll calendering, the contact pressure between calendering roller and paper surface is usually difficult to be uniformly distributed. Due to the reasons such as surface wear of roller and uneven pressure distribution, there may be local uncompacted areas on the surface of paper, which leads to uneven calendering effect and affects printing quality.

[0005] Poor adaptability to paper thickness: traditional roll calendering device usually needs to rely on adjusting the pressure of roller to adapt to paper with different thickness. However, since the contact pressure between roller and paper is fixed, this makes the device have poor adaptability to paper thickness and surface hardness, and it is easy to cause over-calendering of thin paper or insufficient calendering of thick paper.

[0006] Uneven heat pressing: roll calendering often relies on the heat of roller surface for heat pressing treatment, but due to the limited heat conduction performance of roller, the temperature distribution is uneven during calendering process, which may produce areas with excessively high or low temperature, thereby affecting the calendering effect.

[0007] Therefore, the existing problems are researched and improved, and a matt art paper calendering device is provided to solve the existing problems, and the purpose of solving the problems and improving the practical value is achieved through the technology. SUMMARY

[0008] The utility model aims at providing a matt art paper calendering device, which can solve the problems of uneven calendering effect, uneven heat pressing and large equipment wear in the existing technology. Through innovative structure design, the utility model can effectively improve the surface quality of matt art paper, provide uniform and stable heat pressing effect, and the equipment is easy to operate and has low maintenance cost.

[0009] To achieve the above object, the utility model adopts the following technical scheme:

[0010] The matt copperplate paper calendering device of the utility model includes drive seat, a plurality of shafts and a plurality of hot pressing assemblies. Among them, the shafts are synchronously driven through first transmission gear and second transmission gear, ensuring that each shaft can rotate synchronously, so that the plurality of hot pressing assemblies can work cooperatively. The drive seat is provided with a motor, which drives the first transmission gear to rotate, further driving the operation of the whole system.

[0011] The hot pressing assemblies are uniformly arranged on the plurality of shafts, and each group of hot pressing assemblies is sequentially arranged on the surface of the shaft. Each hot pressing assembly includes a wobble plate seat, a hot pressing strip and an eccentric wheel. The hot pressing strip is fixedly installed on the inner side of the wobble plate seat and is slidably connected with the wobble plate seat through a guide pin. The eccentric wheel is sleeved on the surface of the shaft, and the center of the outer circle of the eccentric wheel deviates from the axis of the shaft. The eccentric structure is used to adjust the stress mode of the hot pressing strip, so as to realize uniform hot pressing effect.

[0012] In the utility model, the wobble plate seat and the hot pressing strip are connected through an elastic member, which is a metal spring structure, can provide flexible connection, and ensure that the hot pressing assembly has good adaptability. In the working process, the hot pressing strip can be adjusted according to the different thickness and hardness of the paper, so that each piece of paper can be uniformly hot pressed, and the paper will not be deformed or have different hardness to cause uneven calendering.

[0013] The hot pressing strip is embedded with an electric heating assembly, and is provided with a temperature sensor and a temperature controller. The temperature sensor can monitor the temperature of the hot pressing strip in real time, and through the connection with the temperature controller, the heating efficiency of the hot pressing strip can be accurately controlled. The temperature control system ensures that the hot pressing strip can work at a stable temperature, improves the hot pressing effect, and avoids the problems of paper damage or unsatisfactory calendering effect caused by large temperature fluctuation.

[0014] The hot pressing assembly of the device cooperates with the transmission gear and the transmission teeth through the shaft, realizes the intermittent calendering of the matt copperplate paper surface by the hot pressing strip. The eccentric direction of the eccentric wheel is arranged in S shape, so that the hot pressing strip can cover each area of the paper surface in the movement process, avoiding the missing problem of calendering in the traditional roller pressing device, so as to ensure the comprehensiveness and uniformity of hot pressing.

[0015] In summary, the utility model provides a kind of efficient, uniform and stable matt copperplate paper calendering device by the combination of innovative transmission structure, hot pressing assembly design and temperature control system. The device can solve the problems existing in traditional roller calendering equipment, improve the calendering quality and the adaptability of equipment, and has long service life and low maintenance cost, which is suitable for high-end printing field, and has significant technical advantages for improving the surface quality and printing effect of matt copperplate paper.

[0016] The utility model discloses the obtained beneficial effect is:

[0017] 1. In the utility model, through the even arrangement of multiple hot pressing components on the shaft rod, and through the different eccentric arrangement of eccentric wheels, the even pressure distribution is formed, so that the surface of the matt copperplate paper can be uniformly and comprehensively hot pressed in the movement process.

[0018] 2. In the utility model, through the synchronous transmission between the first transmission tooth and the second transmission tooth, and the driving of the motor to the shaft rod, the shaft rod can be synchronously rotated. The synchronous work effectively avoids the surface calendering uneven problem caused by the inconsistent rotation between different shaft rods, and ensures the stability and precision of the whole calendering process.

[0028] In order to make the purpose, technical scheme and advantage of the utility model more clear and explicit, the utility model is further explained in detail below in combination with specific implementation manners and with reference to the drawings. It should be explained that, in the case of no conflict, the embodiment of the utility model and the features in the embodiment can be combined with each other.

[0029] It is understood that these descriptions are only exemplary, and are not intended to limit the scope of the utility model.

[0030] Brief Description of the Drawings Figures 1-5 Some embodiments of the utility model provide a matt copperplate paper calendering device.

[0031] As Figure 1 shown, the device comprises a driving seat 100, a plurality of shaft rods 200, and a plurality of hot pressing assemblies 300. A motor 110 is installed on the driving seat 100, which drives the first transmission teeth 210 to rotate, thereby driving the shaft rods 200 to rotate synchronously. Through the second transmission teeth 220, the adjacent shaft rods 200 can realize synchronous rotation, ensuring that the plurality of hot pressing assemblies 300 work simultaneously.

[0032] The plurality of hot pressing assemblies 300 are evenly arranged on the shaft rods 200, and each group of hot pressing assemblies 300 is arranged in sequence on the surface of the shaft rods 200, forming a plurality of working zones, which can comprehensively hot-press the matt copperplate paper. Each hot pressing assembly 300 is jointly acted on by a cam plate seat 310, a hot pressing strip 320, and an eccentric wheel 330, forming uniform pressure distribution and performing calendering treatment on the surface of the paper.

[0033] In each hot pressing assembly 300, the hot pressing strip 320 is fixed inside the cam plate seat 310 and is in sliding fit with the cam plate seat 310 through a guide pin 321. The hot pressing strip 320 contacts the paper through its surface, thereby exerting pressure on the paper. An electric heating assembly is embedded in the hot pressing strip 320, which can provide continuous heat during the hot pressing process. The heating efficiency of the electric heating assembly is adjusted by a temperature controller, realizing accurate temperature control.

[0034] The eccentric wheel 330 is sleeved on the surface of the shaft rod 200, and the center of its outer circle deviates from the axis of the shaft rod 200. The eccentric wheel 330 makes the pressure distribution of the hot pressing strip 320 on the surface of the paper more uniform during movement through the eccentric structure, thereby avoiding the problems of local overpressure or uneven calendering that may occur in the traditional roller pressing mode.

[0035] As Figure 4 shown, an electric heating assembly is installed inside the hot pressing strip 320, and each hot pressing strip 320 is provided with a temperature sensor not shown. The temperature sensor monitors the temperature of the hot pressing strip 320 in real time and transmits data to the temperature controller not shown through electrical connection. The temperature controller adjusts the heating power of the electric heating assembly according to the temperature data provided by the sensor, ensuring that the hot pressing strip 320 maintains a constant temperature during the entire calendering process.

[0036] The design of the temperature control system can effectively control the heating effect, avoid the damage to the paper or the uneven calendering effect caused by excessively high or low temperature, and thereby improve the overall calendering quality.

[0037] Between the hot bar 320 and the cam plate base 310, a flexible connection is achieved through the elastic piece 322. The elastic piece 322 is a metal spring structure, which can allow the hot bar 320 to slightly deviate or deform during operation to adapt to paper of different thickness and hardness. This flexible connection design effectively improves the adaptability of the calendering device to different types of paper, ensuring that the hot pressing assembly 300 can always maintain uniform pressure when the thickness of the paper changes or the surface of the paper is uneven.

[0038] In addition, the eccentric structure of the eccentric wheel 330 and the sliding design of the hot bar 320 make each hot pressing assembly 300 form a uniform hot pressing effect on the surface of the paper. Through the eccentric direction of the S-shaped arrangement of the eccentric wheel 330, it further ensures that the paper surface is fully and uniformly covered during hot pressing, avoiding the omission or uneven hot pressing that may occur in the traditional roller pressing method.

[0039] The operation and maintenance of the device are relatively simple. Users only need to adjust the working state of the motor 110 and the set temperature of the temperature control system according to the different requirements of the paper, so as to realize efficient calendering processing of paper of different thickness or surface characteristics. Since the structure of the device is relatively simple and the matching precision between the various components is high, the failure rate is low, and the maintenance cost is relatively low.

[0040] In daily maintenance, the working state of the electric heating assembly and the temperature sensor is mainly checked, and whether the sliding contact between the eccentric wheel 330 and the hot bar 320 is smooth. If necessary, damaged parts can be replaced in time, greatly reducing the equipment downtime and maintenance cost.

[0041] The matte copper plate paper calendering device of the utility model provides a high-efficiency, stable and easy-to-operate calendering solution through accurate synchronous transmission, uniform hot pressing effect, effective temperature control system and flexible connection design with strong adaptability. Its excellent uniformity and flexibility make it have wide application prospect in the field of high-end printing and matte copper plate paper surface treatment.
