Description

Technical Field

[0001] This utility model relates to the technical field of conveying and transporting devices for rolled objects, and in particular to a rewinding machine feeding device. Background Technology

[0002] Rewinding machines are essential pieces of equipment widely used in the paper and film industries, playing a crucial role in the entire production process. Their main purpose is to rewind large rolls of paper or film sequentially into smaller rolls. This is done to adapt to different subsequent production stages or to facilitate product sales.

[0003] There are specific operating procedures for slitting large rolls of paper and film. First, the smaller rolls of core material need to be transported to the rewinder to prepare for rewinding. After rewinding, the smaller rolls of paper or film need to be promptly removed to make room for loading empty core material for secondary rewinding. This cycle is repeated to ensure continuous production.

[0004] Traditionally, operators manually carry a cartload of cores to the rewinding machine. Once the rewinder finishes a roll, the operator must quickly unload the completed roll and replace it with a new core. Because these small rolls of paper and film are still very heavy, operators face significant risks during handling, easily resulting in sprains and strains. Prolonged manual labor can also lead to atrophy and seriously threaten the operators' health. Furthermore, manual handling is extremely inefficient, increasing rewinder downtime, impacting overall production progress, and potentially disrupting the continuity of the production process, thus affecting product yield and quality. With the continuous expansion of production scale and increasingly demanding requirements, traditional manual handling methods are no longer sufficient to meet the needs of modern industrial production and urgently require improvement and optimization.

Detailed Implementation

[0017] The preferred embodiments of the utility model are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the utility model.

[0018] like Figures 1 to 4As shown, a rewinding machine feeding device includes a base 1, a movable seat 2 slidably connected to the base 1 in the horizontal direction, and a mounting base 7 mounted on the movable seat 2. The mounting base 7 plays a connecting role in the entire device. A lifting seat 6 is also mounted vertically on the mounting base 7 using a sliding connection. This design allows the lifting seat 6 to perform precise vertical lifting movements on the mounting base 7, thus flexibly adjusting its height according to different work requirements. A tilting shaft 601 is provided on the lifting seat 6, and a receiving tilting seat 9 is rotatably connected to the tilting shaft 601. The upper surface of the receiving tilting seat 9 is an inverted triangular groove. This inverted triangular groove can better position and fix materials such as core cylinders during material receiving, preventing materials from sliding or falling during movement. Furthermore, the shape of the inverted triangular groove also facilitates the placement and retrieval of materials, improving operational convenience.

[0019] The working process of the feeding device is as follows: First, the moving base 2 moves smoothly along the horizontal direction of the base 1 to the cutting device. The cutting device accurately places the pre-cut core cylinder into the inverted triangular groove of the receiving and flipping base 9. At this time, the receiving and flipping base 9, with its inverted triangular groove structure, can firmly fix the core cylinder, ensuring that the core cylinder will not shake or shift during subsequent movement.

[0020] Next, the movable seat 2 starts again and moves towards the rewinder. When it reaches the rewinder, the rewinder automatically picks up the core tube from the receiving flipping seat 9 and begins the rewinding process. During the rewinding process, the rewinder evenly winds the paper or film onto the core tube to form a complete roll.

[0021] After the rewinding process is completed, the rewinder places the rolled paper or film back into the inverted triangular groove of the receiving and turning seat 9. Then, the moving seat 2 begins to move in the opposite direction, returning towards the cutting device. Once in the appropriate position, the receiving and turning seat 9, driven by the turning shaft 601, flips in the opposite direction to the cutting device. During this flipping process, due to gravity, the rolled paper or film smoothly falls from the inverted triangular groove of the receiving and turning seat 9 into the pre-set storage area. This design makes the unloading process more efficient and smoother, reduces manual intervention, and improves production efficiency.

[0022] After the unloading operation is completed, the receiving and flipping seat 9 waits to receive a new core cylinder from the cutting device. Then, the device repeats the above workflow continuously, realizing the automation and continuity of the unloading process of the rewinding machine.

[0023] This rewinding machine feeding device, through the close cooperation and coordinated work of its various components, realizes a series of operations such as automatic conveying of the core tube, rewinding, and automatic feeding of the roll, which greatly improves the working efficiency and production quality of the rewinding machine and brings significant economic benefits to industrial production.

[0024] The receiving and turning seat 9 is provided with a first end support component 603 and a second end support component 604 at both ends. The first end support component 603 includes an end sliding rod, which is slidably connected to an end adjusting seat 6032, which is connected to an end adjusting cylinder 6031. The second end support component 604 includes an end transition roller 6041 and an end support seat 6042. The first end support component 603 and the second end support component 604 are used to limit the roll, so that the roll is in the middle of the receiving and turning seat 9, and also to prevent the core or the rolled paper and film from falling off from the front and rear ends of the receiving and turning seat 9 during the movement of the receiving and turning seat 9. The end adjusting cylinder 6031 drives the end adjusting seat 6032 to move to adjust the distance between the end adjusting seat 6032 and the end support seat 6042. When the distance between the two is the largest, the core tube can fall into the distance between them. When the distance between the two is reduced, it is used to clamp the two ends of the core tube. Similarly, when the distance between the two is the largest, the roll of paper and film can fall into or be moved out of the distance between them. When the distance between the two is reduced, it is used to clamp the two ends of the roll.

[0025] The lower end of the lifting seat 6 is connected to the tilting power component 602. The output end of the tilting power component 602 is connected to the lower end of the receiving tilting seat 9 through a fisheye connector. The tilting power component 602 is a cylinder or an electric cylinder. When the tilting power component 602 is extended, the receiving tilting seat 9 rotates along the tilting shaft 602, thereby tilting the object on the receiving tilting seat 9 out from the side. When the tilting power component 602 is retracted, the receiving tilting seat 9 returns to the upright position. Therefore, it can be used to support objects.

[0026] The movable seat 2 is connected to the lifting power component 8, and the output end of the lifting power component 8 is connected to the lifting seat 6. The lifting power component 8 is a pneumatic cylinder or an electric cylinder. The lifting power component 8 allows the lifting seat 6 to be raised or lowered, which in turn allows the receiving and tilting seat 9 to be raised or lowered. This enables the receiving and tilting seat 9 to better dock with the cutting machine or rewinding machine, reducing the distance of the rolled material or roll when changing positions and increasing the accuracy of the docking.

[0027] A lifting slide 4 is provided at the center of the movable seat 2. The lifting slide 4 is slidably connected to the lifting plate 401. The upper end of the lifting plate 401 is connected to the lifting seat 6. The lifting slide 4 provides reliable guidance and support for the lifting of the lifting seat 6, preventing the lifting seat 6 from shaking or deviating during movement. Therefore, to further ensure the stability and straightness of the lifting process of the lifting seat 6, a lifting drive shaft 5 is provided on the side of the mounting base 7. The two ends of the lifting drive shaft 5 are connected to lifting gears 501. A lifting rack 502 is connected below the lifting seat 6. The lifting gears 501 and the lifting rack 502 are meshed. When the lifting power component 8 drives the lifting seat 6 to rise and fall, the lifting rack 502 below the lifting seat 6 will move up and down accordingly. Since the lifting gear 501 meshes with the lifting rack 502, the movement of the lifting rack 502 will drive the lifting gear 501 to rotate, which in turn will cause the lifting drive shaft 5 to rotate as well. This gear and rack transmission method has the advantages of high transmission efficiency, high precision, and good stability. It can transmit the power of the lifting power component 8 to the lifting seat 6 more accurately and stably, ensuring that the lifting seat 6 can move up and down according to the predetermined trajectory and speed, further improving the working efficiency and reliability of the entire rewinding machine feeding device.

[0028] A movable rack 103 is provided on the base 1, and a movable seat 2 is connected to a drive motor 3. The drive motor 3 is connected to a drive gear 301, which meshes with the movable rack 103. When the drive motor 3 starts, its power is directly transmitted to the drive gear 301, causing the drive gear 301 to rotate at high speed. The drive gear 301 meshes with the movable rack 103 on the base 1. This meshing connection method cleverly converts the rotational motion of the drive motor 3 into the linear motion of the movable seat 2.

[0029] The base 1 is provided with a sliding rail 101, and a sliding slider 102 is slidably connected to the sliding rail 101. The sliding slider 102 is connected to the movable seat 2. The sliding rail 101 restricts the movement direction of the movable seat 2, ensuring that it can only move along a preset straight track, preventing deviation and shaking, and improving the stability of movement. On the other hand, the sliding of the sliding slider 102 on the sliding rail 101 can effectively reduce friction, making the movement of the movable seat 2 smoother, reducing energy loss, and improving the operating efficiency of the entire device.

[0030] The rewinding machine feeding device of this utility model is equipped with a movable seat 2, which can move between the cutting device and the rewinding machine. The upper end face of the receiving and turning seat 9 is an inverted triangular groove, which can better position and fix the core tube and other materials when receiving materials, preventing the materials from sliding or falling during movement. It also facilitates the placement and retrieval of materials, improving the convenience of operation. Furthermore, by turning the receiving and turning seat 9, the rolled roll can be smoothly dropped into the storage area by gravity, reducing manual intervention, improving production efficiency, and realizing the automation and continuity of the feeding process. Therefore, it realizes a series of operations such as automatic conveying of the core tube, rewinding, and automatic feeding of the roll, which greatly improves the working efficiency and production quality of the rewinding machine and brings significant economic benefits to industrial production.

[0031] Finally, it should be noted that the above are merely preferred embodiments of the utility model and are not intended to limit the utility model.
