Description

Technical Field

[0001] This invention belongs to the field of textile equipment technology, and specifically relates to a fabric roll conveying device. Background Technology

[0002] With the continuous development of Chinese society and the continuous improvement of people's living standards, people's requirements for the quality of clothing are also getting higher and higher, and the production methods of textiles are also constantly being improved. The aforementioned fabric rolls are a common finished product produced when the yarn is woven by the textile machine during the textile production process. For the convenience of processing, storage, and transportation, existing fabric rolls are generally made with a large diameter and heavy weight. Currently, when processing fabric rolls, they need to be transferred to different floors for processing. Usually, multiple workers work together to lift them to the storage point, and gantry cranes or lifting vehicles are used to assist in the completion. However, the storage point for fabric rolls is quite high after being stacked, making this method not only time-consuming and labor-intensive, but also, due to the large weight and volume of the fabric rolls, errors during operation can easily cause injury to the operators, and fabric rolls may fall and cause personal injury accidents, thus posing certain safety hazards.

[0003] Existing Chinese patent literature contains numerous technical information regarding facilities and equipment for conveying fabric rolls, including CN117125653A (a fabric roll lifting and moving device), CN214243687U (a coated roll stacking and transporting device), and CN218560400U (a fabric roll conveying device). However, existing fabric roll conveying equipment has certain drawbacks: most of them have complex component structures and a large number of parts, resulting in high assembly and production costs. At the same time, their load-bearing capacity and structural stability are also poor, making it difficult to meet the transportation needs of larger and heavier fabric rolls. Furthermore, the stability of operation cannot be effectively guaranteed, and fabric rolls are prone to falling off the conveying equipment, resulting in a lack of effective safety assurance. For example, Chinese patent application CN115352784A discloses an "Automatic Fabric Roll Handling Device for Textile Production," which includes a machine body comprising: a fabric storage unit for storing fabric rolls; a weighing unit for weighing the fabric rolls; and a transfer unit for transporting the fabric rolls to the fabric storage unit for storage, or receiving fabric rolls from the fabric storage unit and transporting them to the weighing unit for weighing. By arranging the fabric storage unit and the weighing unit along the same vertical direction, and placing the transfer unit on one side of the fabric storage unit and the weighing unit, the transfer unit only needs to move back and forth in a straight line along the vertical direction to achieve the handover of fabric rolls, thereby improving the transfer efficiency of fabric rolls and effectively enhancing... While this technology offers advantages in production efficiency, factory sophistication, and digital production efficiency, it still suffers from structural complexity, cumbersome assembly, and high costs. During use, the fabric roll cannot be effectively restrained during vertical ascent or descent, or while moving with the housing. The roll is prone to slipping and falling from the conveying device, causing damage to both the roll and the device, thus reducing the efficiency of the fabric roll conveying equipment. Furthermore, existing fabric roll conveying equipment is often only suitable for conveying between two floors, and cannot meet the needs of conveying between multiple floors, such as the first and third floors, resulting in a narrow overall applicability that is no longer suitable for today's diverse usage scenarios.

[0004] In view of the above-mentioned problems, it is necessary to design a device that is simple in structure, saves time and labor, significantly saves space, has a strong load-bearing capacity, and realizes automatic and safe transportation of fabric rolls. This device facilitates the vertical transportation of fabric rolls between multiple floors and has a faster operating speed compared to existing fabric roll conveying equipment, thereby improving production efficiency. To this end, the applicant has ingeniously designed this technical solution. Summary of the Invention

Furthermore, it facilitates fabric roll transport between multiple floors, meeting different usage scenarios and expanding its applicability.

The axial ends of the drive shaft extend outward to the connecting arm plates on the left and right sides. A drive shaft bearing seat is provided on each of the two connecting arm plates at the position corresponding to the drive shaft. The axial ends of the drive shaft are slidably connected to the two drive shaft bearing seats, thereby realizing the sliding connection between the drive shaft and the two connecting arm plates.

[0013] In a further specific embodiment of the present invention, the plurality of supporting claw hooks are constructed in an L-shaped arm plate structure, and each of the plurality of supporting claw hooks includes a supporting claw hook inclined arm and a supporting claw hook bearing arm. The supporting claw hook inclined arm and the supporting claw hook bearing arm are arranged in a vertical state, and the supporting claw hook inclined arm is fixedly connected to the transmission chain and kept parallel to the transmission chain, both of which are inclined. The supporting claw hook bearing arm extends outward from the bottom end of the supporting claw hook inclined arm, and the supporting claw hook bearing arm can lift the fabric roll upward. A bearing arm is also provided on both the left and right sides of the supporting claw hook inclined arm.

Furthermore, the simple structure effectively reduces production costs, and the device can be vertically installed on the outside of a building or inside a factory, occupying little space and facilitating installation and layout with other processes. The multiple conveying devices have strong load-bearing capacity, adapting to the support needs of fabric rolls of different sizes, thus having a wide range of applications. Second, due to the inclined column, the transmission chains in the carrying device and conveying device are also inclined, making the support for the fabric roll more efficient. The supporting claw hooks have an upward tilting tendency, ensuring that the fabric roll will not fall off the supporting claw hooks, thus ensuring the stability and safety of the transportation process. Third, the fabric roll conveying device in this technical solution can meet the needs of fabric roll conveying between multiple floors, i.e., between large heights. By raising the frame and making adaptive changes to the carrying and conveying devices, it can effectively realize fabric roll conveying between multiple floors, thereby expanding the scope of application, meeting the needs of different production scenarios, and better assisting relevant textile manufacturers in their production work. Finally, by setting up a chain bracket that can be adjusted forward and backward, and by correspondingly opening inclined adjustment grooves on the connecting arm plate and the carrying frame on the carrying device, the vertical position of the lower tensioning sprocket can be adjusted, thereby achieving effective adjustment of the tension of the transmission chain, preventing the fabric roll from falling due to the shaking of the transmission chain, and avoiding the phenomenon of tooth slippage or skipping of the transmission chain, further ensuring the reliable and safe performance of the operation.

[0019] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the description of the embodiments is not a limitation on the technical solution. Any formal but not substantive changes made based on the concept of the present invention should be considered within the scope of protection of the present invention.

[0020] In the following description, all directional or positional concepts involving up, down, left, right, front, and back are based on... Figure 1 The positions shown are for reference only and should not be construed as a particular limitation on the technical solutions provided by this invention.

[0021] Please see Figures 1 to 4This document describes a fabric roll conveying device, comprising a frame 1, which includes a bottom platform 11, a pair of longitudinally arranged support plates 12 on the bottom platform 11, and a support platform 13 fixedly connected to the top rear of the two support plates 12. The two support plates 12 are arranged symmetrically from left to right. A pair of inclined columns 14 are formed between the upper end of the bottom platform 11 and the near-top ends of the two support plates 12. A support device 2 is also described, mounted on the frame 1 and connected between the two inclined columns 14. The support device 2 includes a pair of connecting arm plates 21 and multiple support frames 22. The two connecting arm plates 21 are respectively connected to the inner sides of the two inclined columns 14, while the multiple support frames 22 are spaced apart between the two connecting arm plates 21 and fixedly connected to them. Both the two connecting arm plates 21 and the multiple support frames 22 are inclined and have the same inclination angle as the inclined columns 14. Figure 1 As shown, there are three supporting frames 22, but the number can be changed according to actual needs, and the overall width of the supporting device 2 can also be adjusted accordingly, which will not be elaborated further here; multiple fabric roll guide rollers 3 are rotatably connected between the bottom of the supporting frame 22 and a bottom machine platform guide roller frame plate 111 protruding from the top of the bottom machine platform 11, and the multiple fabric roll guide rollers 3 can transport the fabric roll from one side to the other side of the bottom machine platform 11; multiple conveying devices 4 are respectively set on the left and right sides of the multiple supporting frames 22, such as Figure 1 As shown, there are four conveying devices 4, and their number can be adapted to the number of supporting frames 22. Each of the conveying devices 4 includes an upper traction sprocket 41 and a lower tension sprocket 42 respectively disposed at the top and bottom of the side of the supporting frame 22, a transmission chain 43 wound around the upper traction sprocket 41 and the lower tension sprocket 42, and multiple supporting claw hooks 44 fixed on the transmission chain 43. The lower tension sprocket 42 can move up and down to adjust the tension of the transmission chain 43. The transmission chain 43 is also obliquely arranged and parallel to the supporting frame 22. The multiple supporting claw hooks 44 are used to support the fabric roll and lift it up or transport it down. A synchronous drive device 5 is installed on the supporting device 2, and the synchronous drive device 5 is connected to the multiple conveying devices 4 and can drive the transmission chain 43 to rotate.

[0022] In this embodiment, since the device is vertical, it occupies little space and is easy to install and arrange for other processes. Furthermore, by increasing the height of the frame 1, the support device 2 and the conveying device 4 are adapted to each other. This allows the fabric roll conveying device in this technical solution to not only lift the fabric roll from the bottom floor where the bottom machine 11 is located to the second floor, but also to the third or fourth floor, or even the fifth, sixth or higher floor, by placing the support platform 13 of the frame 2 on the upper floor of the second floor. The same applies to the descent of the fabric roll, thus realizing the fabric roll transportation between multiple floors, meeting the needs of different production scenarios, and effectively expanding the scope of application.

The bottom ends of the two aforementioned inclined columns 14 are connected to their respective inclined column connecting beams 114. Furthermore, the inclined columns 14 and the support frame plate 12 combine to form a triangular structure. The triangular structure enables it to form a triangular support, which has a large support strength and can provide sufficient support when the support claw hook 44 supports a large weight of fabric roll, thus ensuring the service life of the frame 1.

And on the left and right side frame plates of the multiple aforementioned bearing frames 22, Furthermore, a bearing frame inclined adjustment groove 222 is also provided at the position corresponding to the aforementioned lower tension sprocket connecting shaft 422. Both the aforementioned connecting arm plate inclined adjustment groove 212 and the bearing frame inclined adjustment groove 222 are inclined, and the inner wall shape of the connecting arm plate inclined adjustment groove 212 and the bearing frame inclined adjustment groove 222 is adapted to the shape of the two ends of the aforementioned lower tension sprocket connecting shaft 422 along its length, allowing the two ends of the aforementioned lower tension sprocket connecting shaft 422 to slide back and forth within the connecting arm plate inclined adjustment groove 212 and the bearing frame inclined adjustment groove 222. A connecting arm plate inclined adjustment groove top connecting seat 2121 is also provided at the top of the aforementioned connecting arm plate inclined adjustment groove 212. The seat 2121 is also equipped with a connecting arm plate inclined adjustment slot bolt 2122.

The ends of the lower tension sprocket connecting shaft 422 along the length direction are screwed together to achieve a fixed connection between the lower tension sprocket connecting shaft 422 and the bearing frame 22. By moving the lower tension sprocket connecting shaft 422 up and down in the inclined adjustment groove 212 of the connecting arm plate and the inclined adjustment groove 222 of the bearing frame, the position of the lower tension sprocket 42 body can be adjusted up and down, thereby adjusting the tension of each transmission chain 43.
