Description

TECHNICAL FIELD

[0001] The utility model relates to a coiled material storage device field, concretely to a coiled material storage mechanism. BACKGROUND

[0002] Coiled materials are applied to many industries, such as steel, papermaking, plastic film, and textile fields, and the production process of such products is usually in a continuous and uninterrupted state. Under such a production mode, coiled materials, as important raw materials or intermediate products, play a key role in maintaining the continuity of production in the storage and supply links.

[0003] The existing coiled material storage mechanism exposes many problems, which are difficult to meet the actual needs of continuous production. The more prominent problem is that when the winding equipment completes the winding work of a coiled material and needs to replace a new coiled material, the production process has to face a temporary pause. Because the existing coiled material storage mechanism lacks effective temporary storage function, it cannot properly store the continuously produced products during this replacement interval, resulting in the products produced during this period being forced to be discarded, causing resource waste, or needing additional manpower and equipment for temporary processing, greatly increasing the production cost and management difficulty.

[0004] Moreover, the existing coiled material storage mechanism has limited storage capacity, and when facing the temporary storage demand generated by replacement, it is also inadequate. In terms of storage tension, its stability is also not satisfactory, and often because of changes in the external environment or small fluctuations in the operation of the equipment itself, the tension on the coiled material is unbalanced, thereby affecting the quality of the coiled material and causing a series of problems in the subsequent processing link. Moreover, the existing equipment is inefficient in space utilization, and needs to occupy a large area of land, which is undoubtedly a great waste of valuable space resources for modern factories.

DETAILED DESCRIPTION

[0048] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0049] Please see Figures 1-5 This application provides the following technical solutions:

[0050] A roll material storage mechanism includes a support unit 1, which is a frame structure. For ease of explanation, it is referred to as... Figure 5 Taking the direction as an example, the lower part of the support unit 1 is a base frame 11, which is a horizontally arranged rectangular frame with casters at the bottom. A feeding rack 12 is located on the upper right side of the base frame 11, and a feeding unit 2 is mounted on the feeding rack 12. A discharging rack 14 is located on the upper left side of the base frame 11, and a discharging unit 5 is mounted on the discharging rack 14. A middle frame 13 is located on the upper middle part of the base frame 11, with its lower end fixedly connected to the base frame 11. The middle frame 13 is located between the feeding rack 12 and the discharging rack 14, and a storage unit 3 and a tensioning unit 4 are mounted on the middle frame 13. The feeding unit 2 serves as the feeding end of this mechanism, used for receiving the roll material, and can accept the roll material 100 input from external structures. After being fed by the feeding unit 2, the roll material 100 enters the storage unit 3, where it is stored in a continuous "S" shape. The tension and slack of the roll material 100 are adjusted by the tensioning unit 4 in the storage unit 3 to adapt to the roll material state in different working conditions. With the help of the discharge unit 5, the roll material 100 in the storage unit 3 is output to an external mechanism to connect with the subsequent roll material processing operation.

[0051] During operation, manual threading of the material is performed first. The head of the roll 100 is inserted through the feeding unit 2, then reciprocates in the storage unit 3, and finally exits through the discharge unit 5 to the next process. Because the preceding roll products are continuously produced, a short pause is required when changing rolls in the subsequent winding section. With this mechanism, when the subsequent winding section stops changing rolls, the roll 100 can be stored within this mechanism, and tension is continuously maintained by the tensioning unit 4 as the roll 100 enters. After the subsequent winding can resume, the tensioning unit 4 releases the roll 100, collecting the roll stored within the mechanism.

[0052] On the basis of the above-mentioned embodiments, the feeding unit 2 comprises a feeding positioning roller set 21 and a feeding guide roller 22. The feeding positioning roller set 21 comprises two vertically arranged feeding positioning rollers, and a spacing is left between the two feeding positioning rollers, which is greater than the width of the roll 100. The feeding positioning rollers are rotationally connected to the feeding frame 12, and a sliding groove is formed on the feeding frame 12. The bottom end of the feeding positioning roller is slidingly connected to the sliding groove on the feeding frame 12, and the feeding positioning roller and the feeding frame 12 are locked by locking bolts. The feeding guide roller 22 is arranged on the side of the feeding positioning roller set 21 facing the storage unit 3. The feeding guide roller 22 is rotationally connected to the feeding frame 12. The feeding guide roller 22 is a horizontally arranged roller body, and the roller shaft direction of the feeding guide roller 22 is perpendicular to the feeding direction of the roll 100.

[0053] The discharging unit 5 comprises a discharging guide roller 51, a discharging positioning roller set 52 and a discharging driving assembly 53 arranged in sequence. The discharging guide roller 51 is arranged close to the storage unit 3, the discharging driving assembly 53 is arranged at the outermost end, and the discharging positioning roller set 52 is located between the discharging guide roller 51 and the discharging driving assembly 53. The discharging guide roller 51 is rotationally connected to the discharging frame 14. The structure of the discharging guide roller 51 is consistent with that of the feeding guide roller 22. The two are arranged in a symmetrical structure with the middle surface of the storage unit 3 as the symmetry surface. The structure of the discharging positioning roller set 52 is consistent with that of the feeding positioning roller set 21, and they are also arranged in a symmetrical structure. The discharging driving assembly 53 comprises a driving discharging roller and a discharging pinch roller. The driving discharging roller is rotationally connected to the discharging frame 14 and is linked with the motor. The driving discharging roller is driven to rotate under the drive of the motor. The discharging pinch roller is arranged above the driving discharging roller and is linked with a cylinder. The discharging pinch roller is driven to move close to or away from the driving discharging roller by the cylinder. The discharging pinch roller is driven to rotate by the driving discharging roller. The roller body structures of the feeding guide roller 22, the discharging guide roller 51 and the discharging pinch roller are consistent. A ring-shaped groove is formed in the middle of the roller body of each of them, and the width of the groove corresponds to the width of the roll 100.

[0054] On the basis of the above-mentioned embodiments, the storage unit 3 comprises a fixed roller set 31 and a movable roller set 32. The tensioning unit 4 comprises a tensioning frame 41 and a tensioning driving assembly 42. The fixed roller set 31 in the present scheme comprises eight fixed rollers. The fixed rollers are rotationally connected to the lower part of the middle frame 13 and are arranged in a straight line array. The direction of the array is the feeding-to-discharging direction. The number of movable rollers in the movable roller set 32 is one more or one less than the number of fixed rollers. The projection of the axis of the movable roller in the horizontal plane is located between the projections of the axes of two adjacent fixed rollers. The number of movable rollers in the present scheme is seven. The movable rollers are rotationally connected to the tensioning frame 41, and the tensioning driving assembly 42 drives the tensioning frame 41 to move in the vertical direction.

[0055] When the subsequent winding operation can be normally wound, the tension frame 41 is located at the lower part of its stroke, and the movable roller set 32 is close to the fixed roller set 31. When the subsequent winding operation is suspended, the tension frame 41 is raised along with the continuous processing of the previous winding product, and the movable roller set 32 is away from the fixed roller set 31, and the processed winding product 100 can be temporarily stored in the storage unit 3.

[0056] On the basis of the above-mentioned embodiment, the middle frame 13 is a door-shaped frame, vertical sliding rails are arranged on the vertical parts on both sides of the frame body, and the frame body rear of the tension frame 41 is slidingly connected with the sliding rails. The front part of the tension frame 41 is a horizontal frame body, and the movable roller is rotatably arranged. The tension driving assembly 42 comprises a tension driving member, and the tension driving member is selected from a cylinder, the cylinder body is vertically arranged, and the lower end of the cylinder body is fixedly connected with the upper side of the chassis 11. The tension driving member is linked with the tension frame 41 through a chain wheel and chain combination. The chain wheel and chain combination comprises two chain wheels, one of which is rotatably connected with the middle frame 13, and the other of which is rotatably connected with the movable end of the tension driving member; one end of the chain is fixedly connected with the tension frame 41, the middle part of the chain is wound around the two chain wheels respectively, and the other end is connected with the upper end of the middle frame 13. The chain wheel and chain combination realizes the linkage with the tension frame 41 through the tension driving member, and because the winding product 100 is wound around the movable roller, the chain wheel and chain structure of this scheme is sufficient to meet the application of the tension force.
