Description

Technical Field

[0001] The utility model relates to the technical field of fabric unwinding, in particular to a fabric unwinding device for textile production. Background Art

[0002] Existing textile machines have all achieved automation and mechanization. Textile workers only need to control the machines and do not need to spin by hand. Some textile machines are equipped with fabric unwinding devices for continuous external feeding of fabrics. The unwinding of fabrics is a very typical application in the textile industry and is often carried out together with the winding process. The unwinding of fabrics means that a stable torque and linear velocity are applied to the unwinding roller through the unwinding mechanism of the unwinding device, and the fabric is gradually pulled out from the unwinding roller.

[0003] At present, for the fabric unwinding device for textile production, the rotation of the unwinding roller is usually controlled by a motor to achieve the unwinding operation of the fabric. However, the motor and the unwinding roller in the existing fabric unwinding device are usually integrally fixed or connected by bolts, and the unwinding roller cannot be quickly disassembled and assembled. After the fabric on the first unwinding roller is unwound, it is inconvenient to quickly replace the next unwinding roller to continue unwinding, and it is inconvenient to use. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problems in the background art and propose a fabric unwinding device for textile production.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A fabric unwinding device for textile production, including a U-shaped fixed seat. A unwinding roller is movably installed in the U-shaped fixed seat, and a driving motor for driving the unwinding roller is movably installed outside the U-shaped fixed seat. An assembly and disassembly component is arranged between the driving motor and the unwinding roller.

[0007] The assembly and disassembly component includes a fixing plate fixedly installed outside the U-shaped fixed seat. A right-angle plate is slidably sleeved on the outer wall of the fixing plate. The driving motor is fixedly installed on the inner side wall of the right-angle plate. A first spring is commonly connected between the inner side of the right-angle plate and the outer side of the U-shaped fixed seat. An electromagnet is fixedly installed on the inner side wall of the right-angle plate. A magnetic block is fixedly installed on the outer side wall of the U-shaped fixed seat, and the magnetic block is arranged opposite to the electromagnet. Both ends of the unwinding roller are coaxially and fixedly installed with rotating shafts. Two insertion blocks are fixedly installed at the driving end of the driving motor, and both insertion blocks are slidably inserted into the ends of the corresponding rotating shafts.

[0008] Preferably, two slots are opened at the end of one of the rotating shafts, and the two slots are separated from or inserted into the two insertion blocks respectively.

[0009] Preferably, a U-shaped seat is slidably arranged in the U-shaped fixing seat, a limiting roller is rotatably installed in the U-shaped seat, and two second springs are commonly connected between the bottom of the U-shaped seat and the U-shaped fixing seat.

[0010] Preferably, disassembly and assembly openings are formed in both side walls of the U-shaped fixing seat, the two disassembly and assembly openings are respectively slidably connected with the two rotating shafts, and one ends of the two disassembly and assembly openings far away from the unwinding roller are inclined downward.

[0011] Preferably, the inner width of the U-shaped fixing seat is equal to the length of the unwinding roller.

[0012] Preferably, sliding grooves are formed in both inner walls of the U-shaped fixing seat, and the sliding grooves are slidably connected with the U-shaped seat.

[0013] Compared with the prior art, the advantages of a fabric unwinding device for textile production provided by the utility model are as follows:

[0014] 1. Due to the elasticity of the two second springs, the limiting roller can adaptively lift and lower along with the thickness of the fabric on the unwinding roller, so that it can always tightly press against the textile fabric on the unwinding roller. Thus, when the unwinding roller stops unwinding the textile fabric, it can tightly press against the textile fabric to prevent the textile fabric from becoming loose and affecting subsequent use.

[0015] 2. When the driving motor controls the unwinding roller to unwind the fabric, the electromagnet is energized and attracted to the magnetic block, so that when the driving motor drives the two insertion blocks to rotate and align with the two slots respectively, the two insertion blocks can automatically insert into the corresponding two slots to complete the installation of the unwinding roller. On the contrary, when stopping unwinding or when the unwinding is completed, the driving motor stops running. At this time, the electromagnet is powered off, and under the action of the first spring, the two insertion blocks on the driving end of the driving motor can be quickly pushed to disengage from the two slots. Finally, the unwinding roller can quickly slide out along the two disassembly and assembly openings under its own gravity, achieving the effect of quickly disassembling, assembling and replacing the unwinding roller, and improving the use effect of the device.

Specific implementation manner

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0021] Refer to Figures 1 to 3 , a fabric unwinding device for textile production, including a U-shaped fixing seat 1, an unwinding roller 2 is movably installed in the U-shaped fixing seat 1, and the inner width of the U-shaped fixing seat 1 is equal to the length of the unwinding roller 2, which can effectively prevent the unwinding roller 2 from shaking in the U-shaped fixing seat 1 and ensure the stability of the unwinding roller 2 when unwinding the fabric.

[0022] A U-shaped seat 12 is slidably arranged in the U-shaped fixing seat 1. Sliding grooves 16 are formed in the inner walls on both sides of the U-shaped fixing seat 1, and the sliding grooves 16 are slidably connected with the U-shaped seat 12. A limiting roller 14 is rotatably installed in the U-shaped seat 12, and two second springs 13 are commonly connected between the bottom of the U-shaped seat 12 and the U-shaped fixing seat 1. Due to the elasticity of the two second springs 13, the limiting roller 14 can adaptively lift and lower with the thickness of the fabric on the unwinding roller 2, so that it can always press against the textile fabric on the unwinding roller 2. Thus, when the unwinding roller 2 no longer unwinds the textile fabric, it can press against the textile fabric to avoid the textile fabric from becoming slack and affecting subsequent use.

[0023] And a driving motor 3 for driving the unwinding roller 2 is movably installed outside the U-shaped fixing seat 1, and a disassembly and assembly component is arranged between the driving motor 3 and the unwinding roller 2; the disassembly and assembly component includes a fixing plate 4 fixedly installed outside the U-shaped fixing seat 1, a right-angle plate 5 is slidably sleeved on the outer wall of the fixing plate 4, the driving motor 3 is fixedly installed on the inner side wall of the right-angle plate 5, a first spring 8 is commonly connected between the inner side of the right-angle plate 5 and the outer side of the U-shaped fixing seat 1, and an electromagnet 6 is fixedly installed on the inner side wall of the right-angle plate 5. A magnetic block 7 is fixedly installed on the outer side wall of the U-shaped fixing seat 1, and the magnetic block 7 is arranged opposite to the electromagnet 6. Rotating shafts 9 are coaxially and fixedly installed at both ends of the unwinding roller 2. Disassembly and assembly openings 15 are formed in the side walls on both sides of the U-shaped fixing seat 1, and the two disassembly and assembly openings 15 are respectively slidably connected with the two rotating shafts 9, and the ends of the two disassembly and assembly openings 15 far away from the unwinding roller 2 are inclined downward, which is convenient for the driving motor 3 to slide out automatically under its own gravity when it is separated from the unwinding roller 2, making the disassembly and installation of the unwinding roller 2 convenient.

[0024] Two inserts 10 are fixedly installed at the driving end of the driving motor 3. Both of the two inserts 10 are slidably inserted into the end of the corresponding rotating shaft 9. Two slots 11 are provided at the end of the rotating shaft 9, and the two slots 11 are separated from or inserted into the two inserts 10 respectively. When in use, when it is necessary to unwind the textile fabric, first, the two rotating shafts 9 on the unwinding roller 2 containing the textile fabric are respectively slid into the two disassembly and assembly openings 15. Then, the driving motor 3 is started, and the electromagnet 6 will also be energized synchronously and attract the magnetic block 7. However, since the magnetic block 7 is fixed, the electromagnet 6 will drive the right-angle plate 5 to approach the U-shaped fixing seat 1, that is, drive the two inserts 10 on the driving end of the driving motor 3 to approach the two slots 11. When the two inserts 10 are driven by the driving motor 3 to rotate and align with the two slots 11 respectively, they will automatically be inserted into the corresponding two slots 11. Thus, under the clamping between the two inserts 10 and the two slots 11, the unwinding roller 2 can be driven to rotate to unwind the textile fabric. When stopping unwinding or when the unwinding is over, the driving motor 3 is stopped. At this time, the electromagnet 6 is powered off and no longer attracts the magnetic block 7. Then, under the action of the first spring 8, the right-angle plate 5 can be quickly pushed away from the U-shaped fixing seat 1 until the two inserts 10 on the driving end of the driving motor 3 are both separated from the two slots 11. Finally, the unwinding roller 2 can slide out quickly along the two disassembly and assembly openings 15 under its own gravity. Then, as described above, replace the next unwinding roller 2, and the effect of quickly disassembling, assembling and replacing the unwinding roller 2 can be achieved, improving the use effect of the device.

[0025] Further explanation, the above fixed connection, unless otherwise clearly specified and limited, should be understood in a broad sense. For example, it can be welding, gluing, or integrally formed setting, etc., which are common means well-known to those skilled in the art.

[0026] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
