Description

Technical Field

[0001] This utility model relates to the field of fabric conveying technology, and more specifically, to a fabric lifting device. Background Technology

[0002] Composite roll fabric is a process that combines two or more different materials together by rolling. This process is often used to manufacture composite roll fabric materials with special properties or functions, such as waterproof, breathable, and abrasion-resistant roll fabrics.

[0003] During the lamination process, the roll of fabric to be laminated is usually lifted by hoisting and then positioned and pushed onto the designated bearing mounting seat for fixation.

[0004] However, due to the heavy weight and large size of the roll of fabric to be laminated, the operator needs to control the suspended roll of fabric to keep it horizontal during the positioning and pushing process. At the same time, the suspended roll of fabric also needs to be precisely suspended above the bearing mounting seat. This method is highly dependent on the operator's skill level and is prone to accidents that threaten the operator's safety. In addition, the operation efficiency is low. Utility Model Content

[0005] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a fabric roll lifting device, which is designed to safely and conveniently lift the fabric roll to be laminated horizontally and accurately place it on the bearing mounting seat.

The first support block is rotatably connected to the telescopic end. One end of the first rotating arm is pivotally connected to the base. The other end of the first rotating arm is provided with a roller. The roller rolls and is limited on the support frame in a horizontal direction.

[0009] According to some embodiments of the present invention, the support frame is provided with a horizontally extending slide groove, and the roller is rotatably connected to the slide groove.

[0010] According to some embodiments of the present invention, the base is provided with a stop block, which is located on the rotation path of the first support block and on the side of the first support block away from the telescopic end.

[0011] According to some embodiments of the present invention, the first rotating arms on both sides of the first support block are symmetrically arranged and the plane of symmetry passes through the center of gravity of the support frame.

[0013] According to some embodiments of this utility model, each pair of the balancing frames is symmetrically arranged.

[0014] According to some embodiments of the present invention, the symmetrical center planes of each pair of the balancing frames coincide and pass through the center of gravity of the support frame.

[0015] According to some embodiments of this utility model, the base is also provided with self-locking casters.

[0016] The fabric roll lifting device according to the present invention has at least the following beneficial effects: When the telescopic component drives the rotating bracket to rotate, the rolling part moves horizontally on the support frame. At this time, the rolling part drives the support frame to move up and down, thereby achieving the purpose of lifting the support frame.

Detailed Implementation

[0022] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0023] In the description of the present invention, it should be understood that descriptions involving orientation, such as the orientation or positional relationship indicated by up, down, etc., are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0024] In the description of this utility model, "multiple" refers to two or more. The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features or their sequential relationship.

[0025] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0026] Reference Figures 1 to 3 As shown, this utility model discloses a fabric lifting device, which includes a base 100, a support frame 200, a telescopic component 300, a rotating bracket 400, a balancing frame 500, a balance bar 600, a synchronous rotating shaft 700, and a lifting base 800.

[0027] Specifically, the support frame 200 is located above the base 100, and the rolled fabric is fixed to the support frame 200, with the length direction of the rolled fabric parallel to the length direction of the support frame 200. The telescopic assembly 300 has a fixed end and a telescopic end, with the fixed end rotatably connected to the base 100. The rotating bracket 400 has rolling parts symmetrically arranged along the width direction of the support frame 200 and a connecting part located in the middle of the rolling parts. The rolling parts are horizontally limited on the support frame 200, and the connecting part is rotatably connected to the telescopic end. It should be noted that the horizontal direction refers to the horizontal plane parallel to the support frame 200 that supports the rolled fabric.

[0028] Multiple pairs of balancing frames 500 are arranged along the length of the support frame 200. When the support frame 200 supports the rolled fabric, to ensure good support on both sides of the support frame 200 in the width direction, the multiple pairs of balancing frames 500 are arranged parallel to each other and symmetrically along the central axis of the support frame 200 in the width direction. Each balancing frame 500 has a first end, a second end, and a third end. The second end is rotatably connected to the support frame 200, and the layout of the first, second, and third ends of all balancing frames 500 is consistent. The two ends of the balance bar 600 are rotatably connected to the third end of the same pair of balancing frames 500. The synchronous rotating shaft 700 is rotatably mounted on the base 100, and the first end on the same side of the support frame 200 in the width direction is sleeved on the synchronous rotating shaft 700. When the forces on both sides of the support frame 200 along its length are uneven, the side with heavier force forces the balance frame 500 to rotate relative to the base 100. Since the first, second, and third ends of all the balance frames 500 are arranged in the same way, under the action of the balance bar 600, the balance frame 500 on the side with lighter force will also rotate relative to the base 100, and the direction of rotation is the same as that of the balance frame 500 on the side with heavier force. In this way, both sides of the support frame 200 along its length will remain horizontal.

[0029] The lifting base 800 is mounted on the base 100. When the fabric lifting device lifts the fabric roll above the bearing mounting seat, the base 100 can be lowered slightly by fine-tuning the lifting base 800, allowing the fabric roll to be precisely placed on the bearing mounting seat. Conversely, when lifting the fabric roll, the base 100 can be raised or lowered slightly by fine-tuning the lifting base 800 to facilitate subsequent fabric placement operations.

[0030] In this embodiment, when the telescopic component 300 drives the rotating bracket 400 to rotate, the rolling part moves horizontally on the support frame 200. At this time, the rolling part will drive the support frame 200 to move up and down, so as to achieve the purpose of lifting the support frame 200. During the process of the rolling part supporting the support frame 200, since the rolling part is symmetrically arranged along the width direction of the support frame 200, it is ensured that the two sides of the width direction of the support frame 200 will not tilt. At the same time, through the cooperation of the balance rotating frame 500, the balance bar 600 and the synchronous rotating shaft 700, the two sides of the length direction of the support frame 200 will not tilt.

[0031] In some embodiments of this utility model, such as Figure 2 , Figure 3As shown, the telescopic assembly 300 includes a telescopic cylinder, the housing 310 of which is rotatably connected to the base, and the telescopic rod 320 of which is rotatably connected to the connecting part. When the telescopic rod 320 extends, it drives the rotating bracket 400 to rotate relative to the base 100, causing the rolling part to move to one side, thereby lifting the support frame 200. When the telescopic rod 320 retracts, it drives the rotating bracket 400 to rotate in the opposite direction relative to the base 100, causing the rolling part to move to the other side, thereby lowering the support frame 200.

[0032] In some embodiments of this utility model, such as Figures 1 to 3 As shown, the rotating bracket 400 includes a first support block 410 and first rotating arms 420 disposed on both sides of the first support block 410. The middle part of the first support block 410 is rotatably connected to the telescopic end. One end of the first rotating arm 420 is pivotally connected to the base 100, and the other end of the first rotating arm 420 is provided with a roller 421. The roller 421 rolls and is limited on the support frame 200 in the horizontal direction. When the telescopic end drives the first support block 410 to rotate, it drives the first rotating arm 420 to rotate as well, thereby driving the roller 421 to move horizontally on the support frame 200. Since the roller 421 is located at the far end of the first rotating arm 420, the height of the roller 421 will change up and down as it rotates with the far end of the first rotating arm 420, thereby causing the height of the support frame 200 to change up and down.

[0033] In this embodiment, the length of the first rotating arm 420 determines the height at which the support frame 200 is lifted, provided that the rolling limit stroke of the roller 421 also meets a certain length, and the telescopic distance of the telescopic end also meets a certain length.

[0034] In order to limit the horizontal rolling of the roller 421 on the support frame 200, in some embodiments of this utility model, such as... Figure 2 , Figure 3 As shown, the support frame 200 is provided with a horizontally extending slide groove 210, and the roller 421 is rotatably connected in the slide groove 210 to ensure that the roller 421 will not detach from the support frame 200.

[0035] In some embodiments of this utility model, such as Figure 2 , Figure 3 As shown, the base 100 is provided with a stop block 110, which is located on the rotation path of the first support block 410. The stop block 110 is also located on the side of the first support block 410 away from the telescopic end. In this way, the final position of the far end of the first rotating arm 420 can be controlled by setting the position of the stop block 110, thereby controlling the height at which the support frame 200 is lifted.

[0036] In some embodiments of this utility model, the first rotating arms 410 on both sides of the first support block 410 are symmetrically arranged and the plane of symmetry passes through the center of gravity of the support frame 200, so as to ensure that the first rotating arms 410 on both sides of the first support block 410 are subjected to balanced forces and to prevent the roller 421 on one side from getting stuck.

[0037] In some embodiments of this utility model, such as Figure 2 As shown, the balance frame 500 includes a second support block 510 and a second rotating arm 520 and a third rotating arm 530 disposed on the second support block 510. The second support block 510 is rotatably connected to the base 100, and the second rotating arm 510 is rotatably connected to the support frame 200 by a pin. The two ends of the balance bar 600 are respectively rotatably connected to the third rotating arm 530 on the same pair of second support blocks 510 by pins.

[0038] In order to ensure that the balance frames 500 on both sides of the support frame 200 are subjected to equal forces, in some embodiments of this utility model, each pair of balance frames 500 is symmetrically arranged in the length direction of the support frame 200.

[0039] In order to ensure that the balancing rotating frames 500 on both sides of the support frame 200 are subjected to equal forces, in some embodiments of this utility model, the symmetry center planes of each pair of balancing rotating frames 500 coincide, and the symmetry center planes pass through the center of gravity of the support frame 200.

[0040] To facilitate the movement of the fabric roll lifting device and to stop its movement, in some embodiments of this utility model, such as... Figures 1 to 3 As shown, the base 100 is also equipped with a self-locking caster wheel 120. When moving, push the self-locking caster wheel 120 to move. When you need to stop and keep it stationary, just lock the self-locking caster wheel 120.

[0041] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
