Positioning and cutting device for preparing 4X4 grid jacquard flannel

Abstract

This utility model discloses a positioning and cutting device for preparing 4x4 square jacquard flannel, relating to the field of jacquard flannel cutting technology. It includes a fixed guide mechanism, with a feeding mechanism supported at its upper end. A cutting mechanism for cutting is laterally arranged on the feeding mechanism. This utility model solves the problem that existing fabric cutting machines require both sides to be pressed and positioned during cutting to prevent fabric deviation, and that when the jacquard flannel continues to move after cutting, it needs to be prevented from deviating from the cutting track. This utility model addresses this by using an inclined feeding plate in the fixed guide mechanism, with a second and third conveying roller group pressing both sides of the jacquard flannel. The inclined cutting blade can move to achieve cutting. After cutting, the jacquard flannel, due to the height difference between the triangular plate and the receiving plate, will push the jacquard flannel forward obliquely. The oblique arrangement of the third conveying roller group in the feeding mechanism is used to receive the obliquely moving jacquard flannel.

Description

Technical Field

[0001] This utility model relates to the field of jacquard flannel cutting technology, specifically a positioning and cutting device for the preparation of 4x4 square jacquard flannel. Background Technology

[0002] The demand for embossed flannel fabrics is surging in the home textile and apparel sectors, with the global market size reaching $2.5 billion in 2023. 4×4 square embossing can enhance the three-dimensionality and functional value of the fabric. The newly developed 4×4 square jacquard flannel has a unique structure and novel visual effect, which can meet consumers' demand for personalized products. This structure can enhance the layering and three-dimensionality of the fabric, making flannel more widely used in the fields of apparel and home textiles, with huge market potential.

[0003] Because of its soft feel, 4x4 square jacquard flannel requires existing fabric cutting machines to press and position it on both sides during cutting to prevent the fabric from shifting during cutting. Furthermore, when the jacquard flannel continues to move after cutting, it is necessary to prevent it from deviating from the cutting track.

[0004] To address the aforementioned issues, a positioning and cutting device for preparing 4x4 square jacquard flannel is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a positioning and cutting device for the preparation of 4x4 square jacquard flannel, which solves the problem in the prior art that existing fabric cutting machines require pressing and positioning on both sides during cutting to prevent the fabric from shifting during cutting, and that when the jacquard flannel continues to move after cutting, it is necessary to prevent it from leaving the cutting movement track.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a positioning and cutting device for preparing 4x4 square jacquard flannel, comprising a fixed guiding mechanism, a feeding mechanism supported at the upper end of the fixed guiding mechanism, a cutting mechanism for cutting arranged horizontally on the feeding mechanism, the fixed guiding mechanism comprising a support frame, a flat plate arranged horizontally at the upper end of the support frame, and an inclined feeding plate arranged obliquely on one side of the upper end of the support frame, the inclined feeding plate comprising a triangular plate and a receiving plate fixed collinearly on their bottom surfaces, the cutting mechanism comprising an oblique cutting blade movably disposed between the triangular plate and the receiving plate, and the feeding mechanism comprising a first conveying roller group and a second conveying roller group disposed on both sides of the flat plate, and a second conveying roller group and a third conveying roller group disposed on both sides of the inclined feeding plate.

[0007] Preferably, the first conveying roller group and the second conveying roller group are fixed vertically, and the third conveying roller group is fixed obliquely.

[0008] Preferably, the feeding mechanism further includes a feeding motor fixed to one side of the first conveying roller group, and sprocket and chain transmission assemblies for transmission are respectively connected to one side of the first conveying roller group and the second conveying roller group, and one side of the second conveying roller group and the third conveying roller group.

[0009] Preferably, the first conveying roller group includes two sets of guide blocks fixed to opposite sides on the upper end of the support frame, and a fixed rotating roller is rotatably connected between the two sets of guide blocks.

[0010] Preferably, the upper ends of the two sets of guide blocks are respectively connected to telescopic rods, and the lower ends of the telescopic rods are rotatably connected to movable rollers.

[0011] Preferably, the cutting mechanism further includes a guide beam connected to one side of the second conveying roller group, on which a movable blade holder is slidably engaged.

[0012] Preferably, the movable tool holder has an internal threaded connection to a threaded rod.

[0013] Preferably, a cutting motor is connected to one side of the threaded rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model provides a positioning and cutting device for preparing 4x4 square jacquard flannel. By setting an inclined feeding plate in the fixed guide mechanism, the inclined feeding plate is set on one side of the second conveying roller group, and one end of the triangular plate is higher than the receiving plate. At the same time, the inclined feeding plate is set at an angle. The second and third conveying roller groups press the two sides of the jacquard flannel. The inclined cutting knife can move to achieve cutting. Due to the height difference between the triangular plate and the receiving plate, the jacquard flannel after cutting will be pushed forward at an angle by the synchronous conveying of the front end of the first and second conveying roller groups until it is flattened by the rotation of the third conveying roller group. Then, the inclined cutting knife can be controlled to move to continue cutting. This solves the problem that existing fabric cutting machines need to press and position both sides during cutting.

[0015] 2. The present invention provides a positioning and cutting device for the preparation of 4x4 square jacquard flannel. The third conveying roller group in the feeding mechanism is set at an angle to receive the jacquard flannel at an angle. The synchronous control of the three conveying roller groups realizes the synchronous conveying of the jacquard flannel at an angle, which solves the problem that existing fabric cutting machines need to prevent the jacquard flannel from leaving the cutting track when it continues to move after cutting.

Detailed Implementation

[0018] 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 protection scope of the present utility model.

[0019] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0020] Combination Figure 1 This utility model discloses a positioning and cutting device for preparing 4x4 square jacquard flannel, comprising a fixed guide mechanism 1, a feeding mechanism 2 supported at the upper end of the fixed guide mechanism 1, and a cutting mechanism 3 for cutting horizontally arranged on the feeding mechanism 2. The fixed guide mechanism 1 includes a support frame 11, a flat plate 12 horizontally arranged at the upper end of the support frame 11, and an inclined feeding plate 13 obliquely arranged on one side of the upper end of the support frame 11. The inclined feeding plate 13 includes a triangular plate 131 and a receiving plate 132 with their bottom surfaces fixed collinearly. The cutting mechanism 3 includes an oblique cutting blade 35 movably arranged between the triangular plate 131 and the receiving plate 132. The feeding mechanism 2 includes a first conveying roller group 23 and a second conveying roller group 24 arranged on both sides of the flat plate 12, and a second conveying roller group 24 and a third conveying roller group 25 arranged on both sides of the inclined feeding plate 13.

[0021] Specifically, the first conveyor roller group 23, the second conveyor roller group 24, and the third conveyor roller group 25 have the same structure, and the flat plate 12 is horizontally set. In this design structure, for the cutting requirements of jacquard flannel, multiple sets of parallel cutters can be set on the upper end of the flat plate 12 to realize the slitting and cutting of jacquard flannel. As the first conveyor roller group 23 and the second conveyor roller group 24 convey the jacquard flannel, automated cutting can be achieved. The inclined feeding plate 13 is set on one side of the second conveyor roller group 24, and one end of the triangular plate 131 is higher than the receiving plate 132. At the same time, the inclined feeding plate 13 is set at an angle. The conveyor roller group 24 and the third conveyor roller group 25 press the two sides of the jacquard flannel. The oblique cutter 35 can move to cut. After cutting, the jacquard flannel will be pushed forward obliquely by the synchronous conveying of the front end of the first conveyor roller group 23 and the second conveyor roller group 24 due to the height difference between the triangular plate 131 and the receiving plate 132. It will continue to be flattened by the rotation of the third conveyor roller group 25. Then the oblique cutter 35 can be controlled to move to continue cutting. The flat plate 12 of this device is equipped with a roller encoder to measure the conveying length. This is prior art and is not shown in the figure.

[0022] The present invention will be further described below with reference to the embodiments.

[0023] Example 1: Combination Figures 2-4 The first conveyor roller group 23 and the second conveyor roller group 24 are fixed vertically, and the third conveyor roller group 25 is fixed obliquely. The oblique setting of the third conveyor roller group 25 is adapted to the oblique conveying of the oblique conveying plate 13. Under the action of gravity, it helps the jacquard flannel to move smoothly to the third conveyor roller group 25.

[0024] The feeding mechanism 2 also includes a feeding motor 21 fixed on one side of the first conveying roller group 23. The first conveying roller group 23 and the second conveying roller group 24 are connected to one side of the first conveying roller group 23 and the second conveying roller group 24, and the second conveying roller group 24 and the third conveying roller group 25 respectively. The feeding motor 21 drives the first conveying roller group 23, the second conveying roller group 24 and the third conveying roller group 25 to rotate synchronously through the two sets of sprocket and chain transmission assemblies 22 to realize the conveying of jacquard flannel.

[0025] The first conveying roller group 23 includes two sets of guide blocks 231 fixed on the upper end of the support frame 11 and opposite to each other. A fixed roller 232 is rotatably connected between the two sets of guide blocks 231 and is rotatably disposed between the two sets of guide blocks 231.

[0026] The upper ends of the two sets of guide blocks 231 are respectively connected to telescopic rods 233, and the lower ends of the telescopic rods 233 are rotatably connected to movable rollers 234. The two sets of telescopic rods 233 are located on both sides of the fixed rollers 232. Synchronization commands are set by PLC or motion controller, and the two sets of telescopic rods 233 drive the movable rollers 234 to rise and fall synchronously on both sides.

[0027] Example 2: Combination Figure 5 The cutting mechanism 3 also includes a guide beam 33 connected to one side of the second conveying roller group 24. A movable knife holder 34 is slidably engaged on the guide beam 33. The guide beam 33 provides sliding guidance for the movable knife holder 34, and the oblique cutter 35 is fixed on one side of the movable knife holder 34. When the jacquard flannel is only conveyed and not cut, the oblique cutter 35 is located at the side end and does not obstruct the conveying of the jacquard flannel.

[0028] The movable blade holder 34 is internally threaded with a threaded rod 32. The rotation of the threaded rod 32 drives the movable blade holder 34 to move along the guide beam 33 to complete the cutting. A protective cover is provided on the outside of the threaded rod 32. The protective cover is existing technology and is not shown in the figure. The protective cover only retains a gap for the movement of the corresponding bevel cutter 35 to reduce the influence of air lint on the cutting of the bevel cutter 35.

[0029] A cutting motor 31 is connected to one side of the threaded rod 32. The cutting motor 31 can rotate in both directions, controlling the threaded rod 32 to rotate in both directions, thereby driving the oblique cutting blade 35 to move back and forth. The cutting motor 31 needs to rotate in both directions to complete the reset for each cut.

Their structure, materials and assembly methods are also common knowledge. Those skilled in the art can directly select suitable components to assemble with the core innovative components of this embodiment according to conventional design specifications.
