Description

An automatic fabric feeding mechanism for stability Technical Field

[0001] This utility model relates to the field of feeding mechanism technology, specifically a stable automatic feeding mechanism for fabric. Background Technology

[0002] During fabric processing, feeding is required. However, existing feeding mechanisms are unstable. Specifically, when the fabric enters the processing equipment, the equipment itself has the ability to clamp and feed the fabric. Therefore, initially, due to the pulling force, the feeding mechanism is pulled outward towards one side of the processing equipment. However, due to the weight of the feeding mechanism itself, it cannot be moved. But this poses a certain danger to the fabric, as the initial pulling force can easily cause the fabric to tear.

[0003] To address these issues, the existing feeding mechanism's motor speed is synchronized with the processing equipment's motor speed. This effectively prevents the aforementioned problems. However, while the motor speed is synchronized, it cannot eliminate the problem of human intervention. Occasionally, when the fabric is conveyed to the processing equipment, human intervention may be used to straighten the fabric's conveying trajectory. This alters the inherent tensile force, thus failing to prevent the fabric from being stretched and torn. Furthermore, in some feeding mechanisms, the fabric height is inconsistent with the height of the processing equipment's inlet, causing the feeding mechanism to experience tensile force in an inclined direction. This can also lead to uneven tensile force, affecting the stability of the feeding mechanism. Additionally, existing feeding mechanisms cannot handle the installation of fabric cylinders with different widths, thus exhibiting limited applicability.

[0004] Therefore, in order to solve the above-mentioned existing problems, achieve more stable fabric conveying, and adapt to the installation of fabric cylinders of different lengths, a stable automatic fabric feeding mechanism is proposed. Summary of the Invention

[0008] Furthermore, the lifting structure includes a hydraulic cylinder; the lower end of the hydraulic cylinder is mounted on the upper surface of the first mounting plate, and its telescopic end is connected to the inner side of the second mounting plate.

[0009] As a preferred technical solution, the feeding structure includes a support structure and a driving structure.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model. Embodiments

[0028] Please refer to Figures 1-9. This utility model provides the following technical solution: a stable automatic fabric feeding mechanism, including a base structure, a mounting structure, and a feeding structure. The mounting structure is located at the upper end of the base structure, and the feeding structure is mounted on the mounting structure. A buffer structure is also mounted at the upper end of the base structure. A lifting structure is also mounted on the base structure and connected to the mounting structure. A bidirectional moving structure is mounted on the mounting structure and connected to the feeding structure, driving the feeding structure to move in the opposite direction. The buffer structure includes an upper mounting block 16, a movable shaft 17, a telescopic spring 18, and a lower mounting block 20. The lower mounting block 20 and the upper mounting block 16 are symmetrically mounted on the base structure. The two sets of lower mounting blocks 20 and the two sets of upper mounting blocks 16 are mounted on... The mounting directions are opposite, and openings are provided on the surfaces of one set of lower mounting blocks 20 and upper mounting blocks 16, while a movable shaft 17 is mounted on the surfaces of the other set of lower mounting blocks 20 and upper mounting blocks 16. A telescopic spring 18 is sleeved on the surface of the movable shaft 17. Its bidirectional moving structure includes a driving structure and a moving structure. The moving structure includes a third mounting plate 10, a fourth mounting plate 14, and a bushing 15. The fourth mounting plate 14 is mounted on the mounting structure, the third mounting plate 10 is mounted on the upper end face of the fourth mounting plate 14, and the bushing 15 is mounted on the lower end face of the fourth mounting plate 14 and connected to the driving structure. A U-shaped groove is provided on the surface of the third mounting plate 10, and openings are provided on both sides of the U-shaped groove on the surface of the third mounting plate 10. The feeding structure is mounted on the third mounting plate 10.

[0029] In this implementation plan, the specific working principle is as follows: During use, the winding mechanism, based on the length of the fabric tube, activates the drive structure to move the third mounting plate 10 in the opposite direction, allowing it to reach a suitable length for easy installation of the fabric tube. During installation, the fabric tube simply needs to be inserted into the U-shaped slot, making it contact the support structure 11. This, in turn, drives the support structure 11 to rotate, causing the fabric tube to rotate and facilitating fabric feeding. Furthermore, the user can adjust the height of the second mounting plate 5 using the lifting structure, based on the height of the processing equipment's feed inlet, thus ensuring the fabric on the fabric tube is in contact with the processing equipment. The height of the feed inlet of the equipment is kept basically consistent to prevent the fabric from being conveyed at an angle due to uneven heights. This would be detrimental to the stability of the mechanism, as the tension of the fabric would be directed in the direction of the inclination and would not be able to keep it horizontal. This would also be detrimental to the buffer structure's ability to cushion the tension. Secondly, as can be seen from Figures 7 and 8, the upper and lower mounting blocks, the movable shaft 17, and the telescopic spring 18 can prevent the fabric from being pulled due to the synchronous speed of the motor when the fabric direction is manually adjusted. This helps to provide a buffering effect and prevents the fabric from tearing when it is pulled.

[0030] As described above, the specific installation structure can be seen in Figures 2-4. The installation structure includes a first mounting plate 4, a second mounting plate 5, a guide column 7, a mounting base 8, and a second slide rail 9. The first mounting plate 4 is mounted on the base structure. The upper end face of the first mounting plate 4 is equipped with a guide column 7, which facilitates the height adjustment of the second mounting plate 5 through the lifting structure. The second mounting plate 5 is in contact with the surface of the first mounting plate 4, and the surface of the second mounting plate 5 has an opening with the same diameter as the guide column 7, through which the guide column 7 passes. The upper end face of the second mounting plate 5 is symmetrically equipped with a mounting base 8, and the upper end face of the mounting base 8 is symmetrically equipped with a second slide rail 9, which facilitates the movement of the fourth mounting plate 14. The surface of the second slide rail 9 is connected to the fourth mounting plate 14. The inner side of the second mounting plate 5 is connected to the upper end face of the first mounting plate 4 by a lifting structure that drives the second mounting plate 5 to adjust its height.

[0031] As described above, the lifting structure can be seen in Figures 1 and 4-5. The lifting structure includes a hydraulic cylinder 6. The lower end of the hydraulic cylinder 6 is installed on the upper surface of the first mounting plate 4, and the telescopic end of the hydraulic cylinder 6 is connected to the inner side of the second mounting plate 5.

[0032] The feeding structure is detailed in Figures 1-3 and 9. It includes a support structure 11 and a driving structure. The support structure 11 comprises a long strip 1101, a first mounting shaft 1102, a first movable wheel 1103, a second mounting shaft 1104, and a second movable wheel 1105. The second mounting shaft 1104 penetrates the third mounting plate 10. One set of the second mounting shafts 1104 located on the lower side of the U-shaped slot has two ends fixedly mounted with second movable wheels 1105 that support the fabric cylinder and drive its rotation. The other set is movable. The left side of the third mounting plate 10 also has a long strip 1101. The surface of the long strip 1101 is fixedly mounted with the first mounting shaft 1102. Both ends of the first mounting shaft 1102 are movably mounted with first movable wheels 1103. Openings are provided at both ends of the surface 1. Bolts are installed in the openings and pass through the openings on the surface of the third mounting plate 10. The bolts are used for fixing. It should be noted that only one set of second mounting shafts 1104 located on the lower side of the U-shaped slot can move through the third mounting plate 10 and be connected to the output end of the motor 22. The remaining first mounting shafts 1102 and second mounting shafts 1104 are fixed. The second movable wheel 1105 on the surface of the movable second mounting shaft 1104 is fixed, while the remaining second movable wheels 1105 and first movable wheels 1103 are movable. In order to facilitate the first movable wheel 1103 to clamp the fabric cylinder and prevent it from dislodging during rotation, the position of the long strip plate 1101 at the opening can be adjusted to clamp the fabric cylinder according to its specific size.

[0033] The specific details of how the drive structure moves the third mounting plate 10 can be seen in Figures 2 and 4. The drive structure includes a geared motor 12, a threaded shaft 13, and a bearing seat 19. The geared motor 12 is mounted on the upper end of the second mounting plate 5, and the bearing seat 19 is symmetrically mounted on the upper end of the second mounting plate 5. The output end of the geared motor 12 is fitted with a threaded shaft 13, which is threadedly connected to a bushing 15 and then connected to the inner ring of the bearing seat 19. The geared motor 12 drives the threaded shaft 13 to rotate, thereby moving the fourth mounting plate 14 through the action of the bushing 15, which in turn drives the third mounting plate 10 to move.

[0034] The specific details of the starting drive structure can be seen in Figures 1 and 2. The drive structure includes a fixed plate 21 and a motor 22. The fixed plate 21 is installed on the outer end face of the third mounting plate 10. The motor 22 is installed on the surface of the fixed plate 21. The output end of the motor 22 is connected to the second mounting shaft 1104. The second mounting shaft 1104 is movably inserted into the surface of the third mounting plate 10. Therefore, the rotation of the second mounting shaft 1104 drives the second movable wheel 1105 to rotate, thereby driving the fabric cylinder to rotate.

[0035] The specific structure of the base can be seen from Figures 1-2. The base structure includes a base 1, a base plate 2, and a first slide rail 3. The base plate 2 is installed between two sets of base 1, wherein two sets of lower mounting blocks 20 and two sets of upper mounting blocks 16 are installed on the lower end face of the first mounting plate 4, and the rest are installed on the upper end face of the base plate 2. The first slide rail 3, which facilitates the movement of the first mounting plate 4, is installed on the upper end face of the base 1.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
