Description

Technical Field

[0001] The utility model relates to an on-site processing technology link in the home textile industry, in particular to a cloth transfer conveyor vehicle. Background Art

[0002] A material transfer vehicle is a vehicle used to transport materials in factories, warehouses, and other locations. It typically consists of a chassis and one or more racks, and can be driven by various methods, including electric, hydraulic, and manual, depending on specific needs. Material transfer vehicles can improve logistics efficiency, reduce labor costs, and minimize product damage during handling.

[0003] In the textile printing, dyeing and weaving industry, semi-finished fabrics produced on looms must undergo various processes, including weaving, finishing, singeing, desizing, mercerizing, shaping, baking, and pre-shrinking, before entering the finished product process and being packaged on a cloth stacking machine and a cloth winding machine before being shipped out. Currently, in production workshops in this industry, semi-finished and finished products produced in these processes are stored and transported in plastic baskets. However, during transportation, the plastic baskets need to be moved to carts. The existing plastic basket transfer process is purely manual, and because the plastic baskets filled with fabric are relatively heavy, moving them to the cart is inconvenient and labor-intensive.

[0004] The main difficulties in fabric transportation are: 1. Fabric is soft and easily stressed, resulting in wrinkles and stretching during handling, which can affect product appearance and quality. 2. The uneven weight distribution of fabric rolls can easily cause them to tilt or slip during handling, increasing handling difficulties and safety risks. 3. Fabric comes in a wide variety of sizes and shapes, requiring the appropriate handling tools and methods to be tailored to the specific situation. Failure to do so can lead to inefficient handling.

[0005] Example of the prior art 1. Referring to the patent document CN107055025A, a transfer trolley for textile printing and dyeing fabrics is disclosed, which includes a first track and a second track arranged in a printing and dyeing workshop. There are trolleys running on the first track and the second track, and a frame for loading plastic baskets is arranged to be lifted on the upper part of the trolley; the trolley includes a square frame, and wheel frames are fixed at the four corners of the lower part of the square frame. Walking wheels are rotatably arranged on the wheel frames, and a guide wheel frame is also fixed on the side of the wheel frame. Two guide wheels are fixed on the guide wheel frame, and the rotation axis of the guide wheel is perpendicular to the rotation axis of the walking wheel; a driving motor electrically connected to a control mechanism is also arranged on the square frame. The output shaft of the driving motor is connected to a transmission mechanism, and the transmission mechanism is connected to the walking wheels. A buffer is arranged at the end of the square frame; the frame includes a "C"-shaped support frame. However, the defects of the technical example 1 are at least: 1. It has a frame. When the fabric size is too large, it cannot be placed into the trolley, that is, the turnover and movement cannot be realized; 2. When it is used, tracks must be laid on the factory site, which is destructive to the site, and the track path is single, and the practicability is extremely poor; 3. There is no auxiliary structure for the fabric to get on and off the trolley, and manual operation is still required, and the labor intensity is still relatively large.

[0006] Example of the prior art 2. Referring to the patent document CN114671370A, a detachable folding lifting transporter for box girders is provided. By arranging rotatable connecting roller assemblies on both sides of the lifting mechanism, and arranging non-powered rollers, intermediate electric rollers and lower electric rollers in the roller assemblies, the stability of the lifting of the lifting mechanism is effectively improved, and the phenomenon of easy wear and jamming in the lifting transmission of the screw motor is reduced, and the functions of auxiliary driving and braking are achieved. By arranging a floating connecting roller assembly on the lifting mechanism and matching with a curved guide rail with a low middle and high ends, the driving power of the screw driving motor at the start of driving can be reduced by the structure itself, and further through partial cancellation, thereby providing stability, improving the adaptability of production operations, and according to the different internal spaces of the box girder, different heights of frames can be selectively selected for guidance to adapt to the operation requirements of different working conditions. However, the defects of the technical example 2 are at least: 1. Both sides of the lifting platform are limited by the frame. When the fabric size is too large, it cannot be placed into the lifting platform, that is, the turnover and movement cannot be realized, and the capacity is greatly limited; 2. The structure is complex, and the overall vehicle cost is high, which is not conducive to large-scale adoption; 3. The structure is complex and the operation requirements are high. Therefore, it is best to be controlled by a professional operator. There are great safety hazards for non-professional operators to operate. Summary of the invention

[0045] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that the embodiments are merely a specific description of the present invention, and their purpose is to allow those skilled in the art to better understand the technical solution of the present invention, and should not be regarded as limiting the present invention.

Therefore, they cannot be understood as limitations on the present invention.

[0047] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0048] Example 1

[0049] Reference Figures 1 to 7 A fabric transfer and conveying vehicle includes a frame 1, which is composed of a horizontal frame 11 and a vertical frame 12, and the vertical frame 12 is fixed to the front end of the horizontal frame 11; a plurality of rollers 13 are installed at the bottom of the horizontal frame 11; a push-pull handle 14 is arranged at the upper end of the vertical frame 12; different from the prior art, it also includes a fabric support frame 2, which is movably located above the horizontal frame 11; a lifting mechanism 3, which is arranged at the front end of the horizontal frame 11, and the lifting mechanism 3 acts on the fabric support frame 2 so that the front end of the fabric support frame 2 has at least a raised position state 2a and a lowered position state 2b; a heightening frame 4 is fixed to the rear end of the horizontal frame 11.

[0050] The above content is the basic structural composition scheme of the utility model, which can control the height of the cloth support frame 2 through the lifting mechanism 3. The specific working principle is:

[0051] When the cloth support frame 2 is in the raised position 2a, the front end of the cloth support frame 2 is higher than the rear end, so that the cloth support frame 2 is tilted downward from front to back. This facilitates unloading operations after transfer into position, that is, with the help of gravity, it can help workers more easily unload the cloth 5 from the cloth support frame 2.

[0052] When the fabric support frame 2 is in the lowered position 2b, the front end of the fabric support frame 2 is lower than the rear end, so that the fabric support frame 2 tilts upward from front to back. This facilitates transportation, as gravity forces the fabric 5 to tilt forward on the fabric support frame 2 and is restrained by the vertical frame 12 to prevent the fabric 5 from rolling off the rear end due to bumps during movement.

[0053] Under the action of the lifting mechanism 3, the fabric support frame 2 is movable relative to the vehicle frame 1. Specifically, the height of the rear end of the fabric support frame 2 remains unchanged, while the height of the front end is adjustable. Therefore, a more flexible connection structure is required between the fabric support frame 2 and the vehicle frame 1. Specifically, the rear end of the fabric support frame 2 is provided with a rotating shaft 21, and the heightening frame 4 is provided with an adapter seat 41. The adapter seat 41 has a rotating hole 411, and the rotating shaft 21 is inserted into the rotating hole 411, so that the fabric support frame 2 is rotatably connected to the adapter seat 41. Therefore, when the fabric support frame 2 is raised or lowered, it rotates around the rear end rotating shaft 21 as the rotation center, achieving the action of raising and lowering the front end while maintaining the height of the rear end unchanged.

[0054] Example 2

[0055] Based on the structure of the first embodiment, the preferred structural scheme of the upgrading mechanism is as follows:

[0056] Reference Figures 1 to 5The lifting mechanism 3 includes an upper fixed plate 31 and a lower fixed plate 32, a movable plate 33, a driving device 34, a screw 35, an upper fixed nut seat 36 and a lower fixed nut seat 37, and a lifting nut seat 38; wherein the upper fixed plate 31 is fixed to the vertical frame 12, and the lower fixed plate 32 is fixed to the horizontal frame 11, so as to realize the installation of the upper fixed bar and the lower fixed plate 32; the upper end of the screw 35 is connected to the upper fixed plate 31 through the upper fixed nut seat 36, and the lower end of the screw 35 is connected to the lower fixed nut seat 37 through the lower fixed nut seat It is connected to the lower fixed plate 32 to realize the installation of the screw 35; the movable plate 33 forms a transmission connection with the screw 35 through the lifting nut seat 38; the driving device 34 acts on the screw 35 to make the screw 35 rotate, so that the screw 35 transmits power to the lifting nut seat 38, so that the lifting nut seat 38 can move up and down along the screw 35, and then the movable plate 33 follows the lifting nut seat 38 to realize up and down lifting actions, so that the front end of the cloth support frame 2 is switched between the raised position state 2a and the lowered position state 2b.

[0057] It is worth mentioning that in order to provide support during the movement and make the lifting process smoother, the lifting mechanism 3 also includes a guide column 391 and a guide sleeve 392. The guide sleeve 392 is fixed on the movable plate 33, and the guide column 391 is inserted into the guide sleeve 392. The upper end of the guide column 391 is connected to the upper fixed plate 31, and the lower end of the guide column 391 is connected to the lower fixed plate 32.

[0058] Preferably, the guide column 391 is provided with a height scale mark 3911, so that the staff can judge the current lifting height by observing the height scale mark 3911 to accurately control the lifting stroke.

[0059] Example 3

[0060] The driving device 34 serves as the power source of the lifting mechanism 3 and has various forms. Two preferred structural solutions are provided here, as follows:

[0061] 1. Electric solution: refer to Figures 1 and 2 The driving device 34 is a motor 341, and the vertical frame 12 is provided with an operating button 342, which forms a control connection with the motor 341. By using the operating button 342, the motor 341 can be controlled to run or stop.

[0062] Furthermore, the vertical frame 12 is provided with a child lock switch 343, which is in communication with the operating button 342. The preferred method of using the child lock switch 343 is to press the child lock switch 3432 repeatedly to release the child lock mode before the operating button 342 can be used normally. If the child lock switch 343 is not used correctly and the child lock mode is not released, pressing the operating button 342 will not control the motor 341.

[0063] 2. Manual solution: refer to Figures 6 and 7 The drive device 34 includes a hand wheel 344, a transmission shaft 345 driven by the hand wheel 344, an input bevel gear 346 mounted on the transmission shaft 345, and an output bevel gear 347 mounted on the lead screw. The hand wheel 344, transmission shaft 345, and lead screw 35 are perpendicularly disposed, and the input bevel gear 346 and output bevel gear 347 mesh to form a transmission connection. When a staff member operates the hand wheel 344, the hand wheel 344 rotates the transmission shaft 345, which transmits power to the output bevel gear 347 via the input bevel gear 346. The output bevel gear 347 then drives the lead screw 35 to rotate.

[0064] Example 4

[0065] Reference Figure 5 This embodiment provides a preferred structural solution for the fabric support frame 2, comprising two lateral frames 22 and a plurality of rolling shafts 23 rotatably connected between the two lateral frames 22. The rolling shafts 23 are configured to roll when subjected to force, thereby converting static friction with the fabric into rolling friction. This allows the fabric to move more easily on the fabric support frame 2, reducing the labor intensity of workers handling the fabric.

[0066] Further, refer to Figures 3 and 4 The fabric support frame 2 further includes a support base 24 fixed to the lower ends of the two lateral frames 22. A stopper 25 is provided on the support base 24. The stopper 25 extends through the gap between two adjacent rolling shafts 23 and extends above the rolling shafts 23. When the fabric support frame 2 tilts, the stopper 25 provides support for the fabric, preventing it from rolling or falling during movement, thereby ensuring stability and safety during use.

[0067] It is worth noting that other technical solutions of the present invention belong to the existing technology and are therefore not described in detail.

[0068] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the concept of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
