Description

TECHNICAL FIELD

[0001] The utility model relates to calender equipment technical field, concretely relates to a kind of feeding platform and multi-roller calender. BACKGROUND

[0002] In today's textile, packaging and many industrial fields involving sheet material processing, calender plays a vital role, which can effectively improve the surface flatness and gloss of the material, meet the high-quality production needs of various products.

[0003] A typical calender, covering the key component of feeding platform, is provided with a machine case on the front side of the feeding platform, and the machine case is internally equipped with a calender roller, and the front side of the machine case serves as a discharge port. In actual production process, the strip-shaped cloth belt is used as a common material to be processed, which needs to be gradually fed into the machine case from the feeding platform, and then subjected to fine treatment by the powerful flattening function of the calender roller, and then smoothly output.

[0004] However, this traditional calender has many inconveniences and hidden dangers in the feeding link. In terms of feeding method, it completely relies on manual operation. The worker first manually places the cloth belt on the feeding platform, and then accurately feeds the front end of the cloth belt into the rotating calender roller in the machine case, and then the cloth belt continuously moves under the traction of the calender roller. In order to ensure that the cloth belt can accurately and stably enter the calender roller, a belt pressing strip is specially arranged on the feeding platform. The belt pressing strip is adjacent to the calender roller in the machine case, and presses the cloth belt by its own weight or simple fixing method, which plays a guiding and directional role for the cloth belt entering the calender roller, so as to ensure that the cloth belt moves along the predetermined path and avoids deviation.

[0005] When multiple cloth belts are processed at the same time, although the production efficiency is improved to some extent, new problems arise one after another. Due to the difficulty in completely synchronizing the conveying progress of each cloth belt in the working process, the situation that one cloth belt is conveyed first often occurs, and the worker needs to add a new cloth belt in time. However, this operation process is extremely tedious. When adding a new cloth belt, the belt pressing strip must be temporarily lifted to create space for feeding the front end of the new cloth belt into the calender roller, and then the belt pressing strip is returned to its original position to press the cloth belt again. Such repeated operation gives rise to a series of problems that cannot be ignored:

[0006] Firstly, in the short moment when the belt pressing strip is temporarily lifted, the cloth belt is instantaneously separated from the restriction and guidance of the belt pressing strip. Due to the flexibility of the cloth belt itself, the disturbance of air flow in the workshop, or even the slight unevenness of the surface of the feeding platform, some cloth belts may move or bend. Once the position of the cloth belt deviates, it cannot be uniformly pressed when entering the calender roller, which directly affects the calendering quality, causes uneven surface flatness and uneven gloss of the product, and greatly increases the rate of defective products.

[0007] Secondly, the pressing strip is arranged close to the calender roller, which is originally for precisely guiding the cloth belt, but brings great safety risk to the operator. When the operator manually takes the pressing strip, the hand is close to the high-speed rotating calender roller, and the clothes, gloves or even fingers can be easily wrapped into the calender roller, causing serious safety accidents, greatly threatening the personal safety of the operator, and also causing the production of the enterprise to stop and economic losses.

[0008] Thirdly, considering different production scales and site layouts, the length of the feeding platform is not fixed. When the feeding platform is designed to be too long, the operator is at the rear end of the feeding platform, far away from the pressing strip at the front end, the length of the stretched arm is limited, and the hand can not reach the pressing strip at all. Therefore, when new cloth belts need to be added, the operator has to frequently run back and forth between the two ends of the feeding platform, greatly reducing the work efficiency, increasing the labor intensity, and also easily causing production rhythm disorder due to operation delay, which cannot meet the needs of efficient and continuous production.

[0009] In summary, the existing calender feeding platform and related feeding method cannot meet the strict requirements of modern industry on production efficiency, product quality and operation safety, and an innovative solution is urgently needed to break this dilemma. Content of the utility model

[0010] In view of the problems pointed out in the background art, the utility model provides a feeding platform and a multi-roller calender to solve the above technical problems.

[0011] The technical scheme of the utility model is as follows:

[0012] A feeding platform comprises a platform body, the front end of the upper side of the platform body is provided with a rotatable conveying roller, and a conveying space is formed between the conveying roller and the platform body.

[0013] The utility model is further provided with a pressing strip, the pressing strip is located on the upper side of the platform body, the two ends of the axial direction of the pressing strip are respectively connected with swing arms, the rear side of the conveying roller is provided with a connecting shaft, and the swing arms are rotationally connected with the connecting shaft.

[0014] The utility model is further provided with the connecting shaft and the conveying roller, the two ends of the connecting shaft are respectively connected with the platform body through connecting seats.

[0015] The utility model is further provided with the pressing strip and the swing arms, and the cross section of the pressing strip is circular.

[0016] The rear end of the swing arm is provided with a threaded hole penetrating through it, the threaded hole is connected with an adjusting screw, and the adjusting screw is in abutting contact with the platform body.

[0017] The connecting shaft is connected with a partition plate, the front end of the partition plate is rotationally connected with the connecting shaft, the partition plate is slidingly connected with the connecting shaft, the rear end of the partition plate is in abutting contact with the platform body, and the partition plate is provided with a plurality of.

[0018] The rear end of the partition plate is in surface contact with the platform body.

[0019] The connecting shaft is spaced apart from the platform body.

[0020] The distance between the conveying roller and the platform body can be adjusted.

[0021] A multi-roller calender comprises the feeding platform, the front end of the feeding platform is provided with a machine box, and the machine box is provided with a calender roller group.

[0022] By adopting the above technical scheme, the utility model has the advantages of:

[0023] In terms of feeding stability, the horizontally arranged platform body in combination with the rotatable conveying roller at the front end is a perfect combination. The conveying space formed by the conveying roller and the platform body provides a standard path for the initial feeding of the cloth tape. As the cloth tape is pulled by the subsequent calender roller group, the conveying roller rotates due to the close contact with the cloth tape, and its own weight and friction can firmly press the cloth tape, avoiding the cloth tape from being raised or deviated in the initial stage, and can also provide a pulling force for the cloth tape, making the cloth tape move towards the calender roller group more smoothly and efficiently, laying a foundation for accurate calendering and greatly reducing the calendering defects caused by unstable feeding.

[0024] The design of the pressing strip and its associated components further improves the feeding accuracy. The pressing strip is parallel to the conveying roller and located on the upper side of the platform body, and forms a flexible control system with the swing arm and the connecting shaft. On the basis of the preliminary pressing of the conveying roller, the pressing strip timely assists and maximally restricts the cloth tape to ensure that it maintains an ideal travel path before entering the calender roller group, ensuring the uniform consistency of the calendering process and improving product quality.

[0025] From the convenience and safety considerations, the advantages are obvious. When adding new cloth tape needs to lift the pressing strip, the cloth tape will not displace under the restriction of the continuously rotating conveying roller, ensuring the continuity of production and reducing the rate of defective products. At the same time, the pressing strip is away from the calender roller, and the operator is completely away from the high-speed rotating component when lifting the hand, eliminating the risk of clothes and limbs being involved, and ensuring personal safety. Moreover, the pressing strip is close to the rear end of the platform, and the staff can conveniently operate on the spot, without long-distance travel, improving work efficiency, reducing labor intensity, and optimizing the feeding process of the calender.

[0033] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0034] The following references Figures 1-5 The present application is described as follows: ​​

[0035] Embodiment: A feeding platform, comprising a horizontally arranged platform body 1, which builds a stable infrastructure for the entire feeding process.

[0036] The front end of the upper side of the platform body 1 is provided with a rotatable conveying roller 2, and the platform body 1 is provided with a hinge seat for rotatably connecting the two ends of the conveying roller 2. In this way, when the cloth passes between the conveying roller 2 and the platform body 1, a conveying space is formed between them for smooth passage of the material. When the cloth enters this area, it is forced to move forward under the strong traction of the subsequent calender roller group. However, in this process, the movement of the cloth will cause the conveying roller 2 to rotate due to the close contact between the cloth and the conveying roller 2. This rotation is not meaningless, on the contrary, the rotating conveying roller 2 plays a dual key role: on the one hand, it firmly presses the cloth with its own weight and friction with the cloth, preventing unnecessary lifting, deviation and other unstable conditions of the cloth during the initial feeding stage; on the other hand, it serves as a booster for the cloth to advance, providing a forward traction for the cloth by rotating itself, so that the cloth can move more smoothly and efficiently towards the calender roller group, laying a good foundation for the subsequent calendering process.

[0037] In addition to the key component of the conveying roller 2, the feeding platform is also equipped with a pressing strip 3. The pressing strip 3 is arranged in parallel with the conveying roller 2 and is accurately positioned on the upper side of the platform body 1. Its two axial ends are respectively connected with the swing arm 4, and the swing arm 4 extends in the front-rear direction.

[0038] On the rear side of the conveying roller 2, a connecting shaft 5 is carefully arranged, which is strictly installed in parallel with the conveying roller 2, and its two ends are stably connected with the platform body 1 through the connecting seat 6, ensuring the stability and reliability of the connection. The front end of the swing arm 4 is cleverly connected with the connecting shaft 5, and this series of connection methods enables the pressing strip 3 to have the ability to adjust the posture flexibly.

[0039] When the actual production runs, the pressing strip 3 intervenes as an auxiliary pressing force on the basis of the initial pressing of the cloth by the conveying roller 2. It can further strengthen the constraint on the cloth, ensuring that the cloth always remains on the ideal path before entering the calender roller group, minimizing the problems of shaking and deviation of the cloth, thereby ensuring the uniformity and consistency of the subsequent calendering process.

[0040] Prevent the displacement of the cloth tape: At the key operation node of adding new cloth tape, according to the traditional feeding method, it is easy to cause the cloth tape position disorder due to improper operation. But in this innovative design, the operator can temporarily lift the pressing strip 3. At this time, the cloth tape is still within the effective limiting range of the conveying roller 2. The conveying roller 2 continues to rotate, and the close-fitting relationship between it and the cloth tape has not changed. Therefore, even if the pressing strip 3 temporarily leaves the pressing position, the cloth tape will not move or bend due to the temporary loss of part of the constraint force, which will affect the production process and product quality. The smooth connection of the new cloth tape provides stable transition conditions.

[0041] Eliminate operation risk: The pressing strip on the traditional feeding platform is close to the calender roller. When the operator manually operates, the hand is easy to approach the high-speed rotating calender roller, which has high safety hidden danger. The pressing strip 3 of the feeding platform is reasonably positioned to be far away from the calender roller. In this way, when the operator manually lifts the pressing strip 3, the hand is kept at a safe distance from the calender roller, completely avoiding the risk of clothes and limbs being wrapped into the calender roller, and effectively ensuring the safety of the operator, creating favorable conditions for safe production.

[0042] Convenient manual operation: Considering the actual production scene, the operator needs to frequently intervene in the feeding link, especially when adding new cloth tape, the convenience of operation is crucial. The pressing strip 3 of the feeding platform is designed close to the rear end of the platform body 1, which makes the distance between the pressing strip 3 and the worker greatly shortened. The worker does not need to run back and forth on the narrow platform as in the traditional platform, or even fumble because they can't reach the operating components. Now they can easily stretch out their hands to lift, put down and other operations on the pressing strip 3, greatly improving the work efficiency, reducing the labor intensity, and making the whole feeding process more smooth and efficient.

[0043] The pressing strip 3 is rotationally connected with the swing arm 4, which gives the pressing strip 3 a certain flexibility. When the cloth tape has slight fluctuations during feeding or needs to adapt to cloth tapes of different thicknesses, the pressing strip 3 can make small adaptive adjustments around the rotational connection point, always maintaining effective contact with the cloth tape.

[0044] The cross section of the pressing strip 3 is circular. Compared with other shapes, the circular shape has a relatively small and uniform contact area when contacting with the cloth tape, reducing the friction damage to the surface of the cloth tape, and also reducing the risk of the cloth tape being hooked, ensuring that the cloth tape can pass through the feeding area smoothly and smoothly.

[0045] The rear end of the swing arm 4 is provided with a threaded hole 7 extending therethrough, and an adjusting screw 8 is connected in the threaded hole 7 and in abutting contact with the platform body 1. This design provides a convenient means for the operator to accurately control the pressing force of the pressing strip 3 on the cloth tape. By rotating the adjusting screw 8 clockwise or counterclockwise, the height position of the pressing strip 3 relative to the platform body 1 can be changed. When it is necessary to increase the pressing force, the screw is tightened, so that the pressing strip 3 is closer to the platform body 1, thereby increasing the pressure on the cloth tape; conversely, loosening the screw reduces the pressing force. This fine adjustment function can adapt to cloth tapes of different materials, thicknesses and tension requirements, ensuring that the cloth tape will not be deformed due to excessive pressing force when feeding, nor will it be loose or deviated, etc., thereby optimizing the stability and accuracy of the feeding.

[0046] The connecting shaft 5 is connected with a partition plate 9, the front end of the partition plate 9 is rotationally connected with the connecting shaft 5, and the partition plate 9 is slidingly connected with the connecting shaft 5. This double connection mode makes the partition plate 9 have high flexibility. When initially installed or adjusted according to production requirements, the partition plate 9 can slide along the connecting shaft 5, so that the operator can quickly adjust the distance between adjacent partition plates 9 to adapt to cloth tapes of different widths. Moreover, when special situations occur, such as impurities need to be cleaned during feeding, or the equipment needs to be maintained, the partition plate 9 is rotated to be perpendicular to the connecting shaft 5, thereby providing more operating space.

[0047] The rear end of the partition plate 9 is in abutting contact with the platform body 1, and the partition plate 9 is provided with a plurality of partition plates. The lower side of the rear end of the partition plate 9 is in surface contact with the platform body 1. Such close contact design ensures the stability of the partition plate 9 during work, and displacement will not occur due to the pulling of the cloth tape or the vibration of the equipment. The plurality of partition plates 9 are arranged adjacent to each other, and form channels for the cloth tape to pass through, thereby accurately and regularly arranging the feeding of the cloth tape. Each cloth tape can orderly proceed along the corresponding channel, effectively avoiding the problem of mutual entanglement and interference between the cloth tapes, thereby further improving the neatness and accuracy of the feeding, and providing a reliable premise guarantee for the subsequent calendering process.

[0048] The connecting shaft 5 is arranged in spaced relation to the platform body 1.

[0049] The distance between the conveying roller 2 and the platform body 1 can be adjusted. This is a very practical design. When facing different thicknesses of cloth belts, the operator only needs to easily change the distance between the conveying roller 2 and the platform body 1 through a specific adjusting mechanism (such as a screw adjusting device, a hydraulic adjusting device, etc., which can be designed according to the actual situation). For thicker cloth belts, the distance is increased to ensure that the cloth belt can pass smoothly and will not be excessively pressed; for thin cloth belts, the distance is appropriately reduced to strengthen the initial pressing effect on the cloth belt. This flexible adjustment capability greatly widens the application range of the feeding platform, enabling it to meet diversified production needs and improving the versatility and adaptability of the equipment.

[0050] A multi-roller calender comprises the feeding platform described above, and a machine box 10 is arranged at the front end of the feeding platform, and a calender roller group 11 is arranged in the machine box 10.

[0051] This multi-roller calender combines various key components. First, the front end is equipped with a carefully designed machine box 10, which is the core area of the calendering operation and stably holds the calender roller group 11 inside, and is closely connected to the feeding platform with many innovative designs described above. This front and rear layout of the feeding platform and the machine box 10 is not random, but complementary to each other and serves the entire calendering process. The feeding platform is responsible for delivering the cloth belt to the front of the machine box 10 in the most optimized state, providing accurate and stable material supply for the subsequent calendering process, ensuring that each cloth belt can meet the calendering process in the correct posture, and the machine box 10 relies on the powerful calender roller group 11 inside to “shape” the cloth belt delivered by the feeding platform, and polish the surface of the cloth belt to the ideal flatness and glossiness.

[0052] The front end of the feeding platform is connected to the machine box 10, and after the cloth belt is preliminarily pressed by the conveying roller 2, assisted by the pressing strip 3 and guided by the partition plate 9, it enters the machine box 10 very smoothly. This transition process benefits from the precise control of the cloth belt by the components of the feeding platform, so that the cloth belt has very small positional deviation and uniform speed when entering the machine box 10, and will not have problems such as jamming and jumping that affect the calendering effect.

[0053] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
