Description

Technical Field

[0001] This utility model relates to the field of yarn cutting equipment technology, and in particular to a yarn roll cutting machine that prevents material jamming. Background Technology

[0002] A yarn spool is a common textile product, consisting of yarn wound onto a spool. In some textile factories, it is often necessary to separate the yarn from the spool.

[0003] However, the current common practice is to place the yarn roll on a conveyor belt and use a hot air cutter to cut the yarn on the roll, while leaving a hole below so that the yarn can fall off, thus achieving the purpose of separation.

[0004] The applicant has discovered that the prior art has at least the following technical problems: the yarn that is easily cut by the above method cannot fall well into the feed port. If the yarn does not fall into the feed port, it will block the conveyor line, causing the conveyor line to stop or move slowly. This will cause the hot air cutter to keep hitting one place, which can easily cause a fire. Utility Model Content

[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0036] In the description of this utility model, it should be understood that the terms "center," "length," "width," "height," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and "side," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0037] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0038] This utility model provides a yarn roll cutting machine that prevents jamming. The cutting and separating processes are placed at two separate stations, which can effectively prevent jamming at the cutting and separating stations and prevent jamming near the cutter. It can cut and separate yarn efficiently and without error.

[0039] The following is combined Figures 1-4 The technical solution provided by this utility model will be described in more detail.

[0040] See Figures 1-4As shown, the anti-jamming yarn roll cutting machine provided by this utility model includes a frame 10, a conveyor line, a cutter 28, a limiting rod 27, a roll placement frame 18, and a yarn receiving part. The conveyor line is movably mounted on the frame 10 and is used to convey rolls and yarn. The cutter 28 is located on the frame 10 and is used to cut the yarn on the roll. The yarn receiving part is located below the discharge end of the conveyor line, and the roll placement frame 18 is located in front of the yarn receiving part. The limiting rod 27 is fixed to the frame 10, extends beyond the discharge end of the conveyor line, and extends above the roll placement frame 18. All limiting rods 27 cooperate to suspend the roll. The roll suspended above all limiting rods 27 can fall from the discharge end of the limiting rod 27 into the roll placement frame 18 under the push of the rear roll.

[0041] The frame 10 is fixed with a support block 13, and the cutter 28 is located on the support block 13. There are one or more cutters 28. The cutter 28 is a hot air cutter 28, used to cut the yarn on the conveyed roll.

[0042] In this embodiment of the anti-jamming yarn roll cutting machine, when the conveyor line is conveying a roll of yarn, the yarn is cut by the cutter 28 as the roll passes through it. The cut yarn remains on the conveyor line and continues to move along with the roll. This structure effectively cuts the yarn without damaging the roll. The yarn is fed at the unloading end of the conveyor line, and the roll is pushed to the discharge end of the limit rod 27, thus completing the separation. The cutting and separation are placed at two separate stations, which effectively prevents jamming at the cutting and separation stations and prevents jamming near the cutter 28, enabling efficient and error-free cutting and separation.

[0043] In traditional wire cutting processes, if the material gets stuck near the hot air cutter 28, an open flame will be generated within 20 seconds, which can easily cause a fire and result in casualties. This equipment can avoid this situation and can cut and separate wires efficiently and without error.

[0044] As an optional implementation, in this embodiment, the limiting rod 27 is mounted on the entire conveyor line, with the starting end of the limiting rod 27 located at the loading end of the conveyor line; see also Figure 1 and Figure 2 As shown, there are at least two limiting rods 27, and there is a gap between adjacent limiting rods 27.

[0045] The distance between the two limiting rods 27 is less than the width of the drum, thus supporting and suspending the drum. The yarn is fed at the feeding end of the conveyor line, and the drum continues to be pushed until it falls from the feeding end of the limiting rods 27 into the drum placement frame 18, thereby achieving separate feeding of the yarn and the drum.

[0046] As an optional implementation, see Figure 1 and Figure 2 As shown, the conveyor line includes a drive unit 26, a conveyor chain 24, and push blocks 25. The drive unit 26 is connected to the conveyor chain 24 for driving the chain to reciprocate. The push blocks 25 are fixed to the conveyor chain 24 and are spaced apart along the length of the chain to abut against the end of the drum. The frame 10 includes a transport support 20. The conveyor line also includes a drive sprocket and a driven sprocket. The drive sprocket and driven sprocket are located at both ends of the transport support 20. The drive unit 26 is connected to the drive sprocket for driving its rotation. The conveyor chain 24 meshes with the drive sprocket and driven sprocket and moves between them.

[0047] For details, see Figure 1 and Figure 2 As shown, a connecting block 29 is fixedly connected to the right end face of the transport bracket 20, connecting the front and rear transport brackets 20 together. A drive device 26 is fixedly connected to the left rear end face of the rear transport bracket 20, and a drive shaft 30 is drivenly connected to the drive device 26. A bearing seat 21 is fixedly connected to the left front end face of the front transport bracket 20, and the bearing seat 21 and the drive shaft 30 are drivenly connected. A drive sprocket is fixedly connected to the drive shaft 30. A driven shaft 22 is rotatably connected to the right end of the transport bracket 20, penetrating the transport bracket 20. A driven sprocket is fixedly connected to the driven shaft 22. A conveyor chain 24 is connected to the drive sprocket and the driven sprocket. Each conveyor chain 24 has a drive sprocket on it. Push blocks 25 are fixedly connected at intervals, and limit rods 27 are fixedly connected to the upper surface of the transport bracket 20. The left end of the limit rod 27 extends out of the transport bracket 20. When the roll carrying the yarn comes out of the feeding mechanism, it will be located on the conveyor chain 24. The drive device 26 rotates, driving the transmission shaft 30 and the transmission sprocket to rotate, thereby driving the conveyor chain 24 to move. The movement of the conveyor chain 24 causes the push blocks 25 fixed on the conveyor chain 24 to move. The upper push block 25 moves to the left, thereby pushing the roll to the left to complete the transport. This structure can effectively transport the roll, and the push blocks can reliably push it, avoiding sliding friction from affecting the transport.

[0048] As an optional implementation, the anti-jamming yarn roll cutting machine also includes a stripping block 15, wherein: the stripping block 15 is located above the unloading end of the conveyor line, and the stripping block 15 includes an arc-shaped stripping piece 151, which is attached to the surface of the roll and is used to strip excess yarn on the roll.

[0049] The arc-shaped stripper 151 can further strip the residual yarn on the roll, effectively separating the yarn from the roll a second time to prevent material jamming.

[0050] As an optional implementation, see Figure 4 As shown, the anti-jamming yarn roll cutting machine also includes a fixed block 14, a positioning post 141, and an elastic part 142. The fixed block 14 is fixed on the frame 10, the positioning post 141 is fixed on the fixed block 14, the positioning post 141 is slidably connected to the peeling block 15, and the elastic part 142 is sleeved on the positioning post 141. The elastic part 142 is used to drive the arc-shaped peeling piece 151 to stick tightly to the surface of the roll.

[0051] The elastic part 142 can be a spring. When the spring is in a compressed state, it can always drive the arc-shaped peeling strip 151 to stick tightly to the surface of the roll, thereby improving the peeling effect.

[0052] As an optional implementation, the anti-jamming yarn roll cutting machine also includes a feeding elevator 12, which is used to transport the yarn rolls wound on the conveyor line.

[0053] The feeding elevator 12 includes an inlet and a feeding tray, which can transport the raw materials from the inlet to the feeding tray and then to the conveyor line. The feeding elevator 12 can be a vibrating screw feeder or similar existing mature technology, which will not be elaborated upon here. After the worker puts the material into the inlet 23 of the feeding elevator 12, the material moves upward with the feeding elevator 12 under its action. After being transported to the top, the material falls from the outlet of the elevator and into the feeding tray 11. Then, the yarn roll is lifted upward by the feeding tray 11 and sent to the conveyor line for operation. This structure can continuously and effectively feed materials, avoiding accidents such as material jamming, and ensuring the continuous and stable operation of the equipment.

[0054] As an optional implementation, the anti-jamming yarn roll cutting machine also includes a yarn placement frame 19 and a feeding elevator 17, wherein: the inlet of the feeding elevator 17 serves as a yarn receiving part and is located below the discharge end of the conveyor line; the feeding elevator 17 is used to convey the yarn to the yarn placement frame 19.

[0055] The feeding elevator 17 can be a vibrating screw feeder or other existing mature technology, which will not be elaborated here.

[0056] See Figure 1As shown, when the yarn on the conveyor chain 24 is transported to the left, it detaches from the conveyor chain 24 and falls into the unloading elevator 17. The unloading elevator 17 then transports it to the yarn placement frame 19. When the roll on the conveyor chain 24 is transported to the left, it is suspended by the limiting rod 27. At the same time, the top of the roll contacts the stripping block 15. If there is still waste yarn on the roll that has not been cut by the front, the stripping block can strip the remaining yarn and let it fall into the yarn placement frame 19. As more and more rolls move to the left, they push the roll in front to the left until the roll detaches from the limiting rod 27 and falls into the roll placement frame 18. This structure can effectively strip the yarn on the roll and also effectively separate the two, preventing material jamming.
