Description

Technical Field

[0001] This utility model relates to the field of towel testing technology, specifically a finished towel testing device. Background Technology

[0002] The finished towel inspection device is a specialized piece of equipment that efficiently and accurately detects key quality indicators of finished towels, such as appearance defects, dimensional accuracy, weight uniformity, and color fastness. This ensures that finished towels meet production standards and market demands, and is widely used in the final quality inspection stage of towel production lines in the textile printing and dyeing industry. Dimensional stability of finished towels refers to their ability to resist shrinkage, stretching, or deformation during washing, drying, and storage. Dimensional stability is an important indicator of towel durability and user experience. It is mainly affected by fiber type, weaving process, and dyeing and finishing treatment. Testing typically simulates actual usage scenarios, measuring the length and width change rate after multiple washes and dries. The acceptable shrinkage rate of finished towels should generally be controlled within 3%.

[0003] The towel finished product testing device requires the testing personnel to pre-process the towel samples before testing. Select representative samples without obvious defects, and then use a tape measure or laser length measuring instrument with an accuracy of 1mm to select three evenly distributed measurement points in the length and width directions of the towel. Wash the towel multiple times and then dry it. After washing, the towel finished product needs to be manually transferred to the drying equipment for quick drying. The towel needs to be washed and dried multiple times before testing. The towel transfer process prolongs the washing and drying time, thus affecting the towel testing efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is that when existing towel finished product testing devices are used, the towels are washed and then transferred to the drying equipment, which prolongs the towel pretreatment time and affects the towel testing efficiency.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A towel finished product testing device includes a frame, a cleaning tank installed on the frame for holding washing liquid, two first rollers rotatably connected to the frame, several protrusions fixedly connected to the first rollers, two second rollers rotatably connected to the frame, the first rollers and second rollers pressing the surface of the finished towel when rotating, a mounting seat coaxially installed on the second roller, a first sleeve coaxially installed on the mounting seat, a coil installed inside the mounting seat, a second sleeve fixedly connected to the first sleeve, a through groove opened in the middle of each second sleeve, a threaded groove opened on the mounting seat for threaded connection of the second sleeve, a rotating shaft rotatably connected to the frame, two sets of first and second discs coaxially installed on the rotating shaft, a connecting strip wound on each of the first and second discs, the bottom end of each connecting strip woven with Velcro, the Velcro being used to attach the corners of the towel.

[0006] The beneficial effects of this utility model are as follows: by setting up a frame, a washing tank, a first roller, a second roller, a rotating shaft, a first disc, a second disc, a connecting belt, a protrusion, a mounting base, a first sleeve, a coil, and a second sleeve, when the rotating shaft rotates clockwise, it pulls the towel attached to the Velcro away from the washing tank and then passes through the first roller and the second roller respectively. The protrusion increases the surface area on the first roller, improving the efficiency of towel squeezing and dehydration. When the coil is powered on, it can heat the second sleeve, the first sleeve, and the second roller, thereby accelerating the drying of the towel. When the rotating shaft rotates counterclockwise, the towel passes through the second roller and the first roller respectively and falls into the washing tank for soaking again. This can shorten the time for towel soaking, drying, and transportation, improve the efficiency of towel pretreatment, and thus improve the efficiency of towel detection.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, a first drive assembly is provided on the frame. The first drive assembly includes a first motor fixedly connected to the frame, a first sprocket fixedly connected to one end of a first roller shaft, a second sprocket fixedly connected to one end of a second roller shaft, a third sprocket fixedly connected to one end of a rotating shaft, a fourth sprocket fixedly connected to one of the second sprockets, a first chain meshing with the first sprocket and the second sprocket, and a second chain meshing with the third sprocket and the fourth sprocket.

[0009] Furthermore, the output end of the first motor is fixedly connected to one of the first sprockets. When the first motor starts, it drives the first sprocket and the first roller to rotate. When the first sprocket rotates, it drives the second sprocket, the fourth sprocket and the second roller to rotate synchronously. When the fourth sprocket rotates, it drives the third sprocket and the rotating shaft to rotate synchronously. When the rotating shaft rotates, it drives the first wheel and the second wheel to rotate. The connecting belt is wrapped around the first wheel and the second wheel respectively. The connecting belt pulls the towel through the gap between the first roller and the second roller.

[0010] Furthermore, a first drive assembly is provided on the frame, and a second drive assembly includes a second motor fixedly connected to the frame, the output end of the second motor being fixedly connected to another first sprocket.

[0011] Furthermore, when the second motor starts, it can drive another first sprocket and the first roller to rotate, and when the second sprocket rotates, it drives another second sprocket and the second roller to rotate.

[0012] Furthermore, two exhaust pipes are installed on the frame, and the exhaust pipes are inserted into the middle of the second roller in sequence. Each exhaust pipe is equipped with a nozzle, which faces the surface of the towel. Several horizontal slits are opened on the second roller to allow air to circulate.

[0013] Furthermore, a fan is installed on the frame, and a connecting pipe is installed at the air outlet of the fan. Each connecting pipe is connected to one end of an exhaust pipe. The exhaust pipes are sequentially inserted into the middle of the through slot, and a filter canister is installed at the air inlet of the fan.

[0014] Furthermore, each of the second discs has a circular groove for the rotating shaft to slide, and each of the second discs has a shrinking sleeve coaxially mounted, with a shrinking bolt threaded onto the shrinking sleeve.

[0015] The beneficial effects of adopting the above-mentioned further solution are as follows: by setting up a fan, exhaust pipe, horizontal slit, and through groove, with the exhaust pipe passing through the through groove, the second sleeve can heat the exhaust pipe, thereby heating the air inside the exhaust pipe. The warm air is then blown onto the towel surface through the horizontal slit, improving the towel drying efficiency. By setting up a second wheel, circular groove, expansion sleeve, and expansion bolt, the tightness of the expansion sleeve attached to the rotating shaft can be adjusted by rotating the expansion bolt, thereby facilitating the sliding of the second wheel and changing the distance between the first and second wheels, thereby improving the adaptability of towel hoisting.

In the description of this application, "a plurality of" means two or more, unless otherwise precisely specified.

[0019] like Figure 1-6As shown, a finished towel inspection device includes a frame 1, on which a cleaning tank 2 is installed. The cleaning tank 2 is used to hold washing liquid for washing and soaking finished towels. Two first rollers 3 are rotatably connected to the frame 1. Several protrusions 18 are fixedly connected to the first rollers 3. The first rollers 3 are symmetrically distributed, and the protrusions 18 are used to increase the surface area of ​​the first rollers 3. When the towels are soaked in water and pass through the two first rollers 3, they are squeezed and dehydrated by the first rollers 3 and the protrusions 18. Two second rollers 4 are rotatably connected to the frame 1. When the first rollers 3 and the second rollers 4 rotate, they squeeze the surface of the finished towels. A mounting base 2 is coaxially installed on the second rollers 4. 2. The mounting base 22 is made of plastic and is used for support and limiting. A first sleeve 23 is coaxially mounted on the mounting base 22. A coil 24 is installed inside the mounting base 22. A second sleeve 26 is fixedly connected to the first sleeve 23. The first sleeve 23 and the second sleeve 26 are made of stainless steel and are fixedly connected to form an integral structure. A through groove 30 is opened in the middle of the second sleeve 26. A threaded groove 25 is opened on the mounting base 22 for threaded connection of the second sleeve 26. The second sleeve 26 is inserted into the middle of the coil 24. When the coil 24 is connected to an alternating current, it will generate an alternating magnetic field. If there is a conductive metal material in the magnetic field, an eddy current closed current will be induced inside the metal. The eddy current... Under the action of metal resistance, electrical energy is converted into heat energy according to Joule's law, causing the metal itself to heat up, thereby heating the second sleeve 26 and the first sleeve 23. The heat from the first sleeve 23 radiates to the second roller 4 to heat the towel. A rotating shaft 5 is rotatably connected to the frame 1. Two sets of first discs 6 and second discs 7 are coaxially mounted on the rotating shaft 5. Connecting straps 8 are wound around both the first discs 6 and the second discs 7. The bottom end of each connecting strap 8 is woven with Velcro 21, which is used to attach the corners of the towel. The machine is equipped with a frame 1, a washing tank 2, a first roller 3, a second roller 4, a rotating shaft 5, first discs 6 and second discs 7, connecting straps 8, and protrusions 18. The system consists of a mounting base 22, a first sleeve 23, a coil 24, and a second sleeve 26. When the rotating shaft 5 rotates clockwise, it pulls the towel attached to the Velcro 21 away from the washing tank 2 and then passes through the first roller shaft 3 and the second roller shaft 4 respectively. The protrusion 18 increases the surface area on the first roller shaft 3, improving the efficiency of towel dehydration. When the coil 24 is powered on, it can heat the second sleeve 26, the first sleeve 23, and the second roller shaft 4, thereby accelerating towel drying. When the rotating shaft 5 rotates counterclockwise, the towel passes through the second roller shaft 4 and the first roller shaft 3 respectively and falls into the washing tank 2 for soaking again. This can shorten the time for towel soaking, drying, and transportation, improve the efficiency of towel pretreatment, and thus improve the efficiency of towel detection.

[0020] like Figure 1-3As shown, a first drive assembly is provided on the frame 1. The first drive assembly includes a first motor 11 fixedly connected to the frame 1 by bolts, a first sprocket 12 fixedly connected to one end of the first roller shaft 3, a second sprocket 13 fixedly connected to one end of the second roller shaft 4, a third sprocket 14 fixedly connected to one end of the rotating shaft 5, a fourth sprocket 17 fixedly connected to one of the second sprockets 13, a first chain 15 meshing with the first sprocket 12 and the second sprocket 13, and a second chain 16 meshing with the third sprocket 14 and the fourth sprocket 17. The output end of the first motor 11 is fixedly connected to one of the first sprockets 12 via a coupling. When the first motor 11 starts, it drives the first sprocket 12 and the first roller shaft 3 to rotate. When the first sprocket 12 rotates, it drives the second sprocket 13, the fourth sprocket 17, and the second roller shaft 4 to rotate synchronously. When the fourth sprocket 17 rotates, it drives the third sprocket 14 and the rotating shaft 5 to rotate synchronously. When the rotating shaft 5 rotates, it drives the first disc 6 and the second roller shaft 4 to rotate synchronously. The wheel 7 rotates, and the connecting belt 8 is wrapped around the first wheel 6 and the first wheel 6 respectively. The connecting belt 8 pulls the towel through the gap between the first roller 3 and the second roller 4. The frame 1 is equipped with a first drive assembly. The second drive assembly includes a second motor 20 fixedly connected to the frame 1. The output end of the second motor 20 is fixedly connected to another first sprocket 12. When the second motor 20 is started, it can drive the other first sprocket 12 and the first roller 3 to rotate. When the second sprocket 13 rotates, it drives the other second sprocket 13 and the second roller 4 to rotate. The first motor 11 and the second motor 20 are both servo motors that can switch between clockwise and counterclockwise rotation. By starting the first motor 11, a set of first rollers 3 and second rollers 4 can be driven to rotate clockwise synchronously with the rotating shaft 5. By starting the second motor 20, another set of first rollers 3 and second rollers 4 can be driven to rotate counterclockwise. The rotation of the first rollers 3 and second rollers 4 in coordination improves the stability of the vertical movement of the towel.

[0021] In practical use, this invention can also replace the first sprocket 12, the second sprocket 13, the third sprocket 14, and the fourth sprocket 17 with a synchronous pulley, and replace the first chain 15 and the second chain 16 with a synchronous belt. The output end of the first motor 11 is fixed on a synchronous pulley, and the output end of the second motor 20 is fixedly connected to another synchronous pulley. Through the transmission cooperation of the synchronous pulley and the synchronous belt, when the first motor 11 is started, it can drive a set of first rollers 3 and second rollers 4 to rotate counterclockwise synchronously with the rotating shaft 5. When the second motor 20 is started, it drives another set of first rollers 3 and second rollers 4 to rotate clockwise. The rotation cooperation of the first rollers 3 and second rollers 4 improves the stability of the vertical movement of the towel.

[0022] like Figure 1-5As shown, two exhaust pipes 10 are installed on the frame 1. The exhaust pipes 10 are sequentially inserted into the middle of the second roller 4. Each exhaust pipe 10 is equipped with a nozzle, which faces the surface of the towel. Several transverse slits 19 are opened on the second roller 4 to allow air circulation. A fan 9 is installed on the frame 1. A connecting pipe is installed at the air outlet of the fan 9. The connecting pipe is connected to one end of the exhaust pipe 10. The exhaust pipes 10 are sequentially inserted into the middle of the through groove 30. A filter canister is installed at the air inlet of the fan 9. A non-woven filter bag is installed in the filter canister to filter impurities in the air. The exhaust pipe 10 passes through the through groove 30, which facilitates heating the air blown out through the exhaust pipe 10. The warm air is then blown onto the surface of the towel through the transverse slits 19, which improves the towel drying efficiency.

[0023] like Figure 3 and 6 As shown, each of the second wheel discs 7 has a circular groove 27 for the rotating shaft 5 to slide. Each of the second wheel discs 7 has a tightening sleeve 28 coaxially mounted on it. Each tightening sleeve 28 is threaded with a tightening bolt 29. By rotating the tightening bolt 29, the tightness of the tightening sleeve 28 attached to the rotating shaft 5 can be adjusted, thereby facilitating the sliding of the second wheel disc 7 and changing the distance between the first wheel disc 6 and the second wheel disc 7, thereby improving the adaptability of towel hoisting.

[0024] Working principle: When using this towel finished product inspection device, the operator first connects to an external power supply, then passes the connecting strap 8 through the gap between the second roller 4 and the first roller 3, and then attaches the two corners of the towel to the Velcro 21. The connecting strap 8 is lowered by rotating the rotating shaft 5 counterclockwise, thus immersing the towel in the washing tank 2 for cleaning. When drying is required, starting the first motor 11 drives a set of first roller 3 and second roller 4 to rotate clockwise synchronously with the rotating shaft 5. Starting the second motor 20 drives another set of first roller 3 and second roller 4 to rotate counterclockwise, pulling the towel along the connecting strap 8. The towels detach from the washing tank 2 and pass through the gap between the first roller 3 and the second roller 4. The protrusion 18 increases the surface area on the first roller 3, improving the efficiency of towel squeezing and dehydration. When the coil 24 is powered on, it can heat the second sleeve 26, the first sleeve 23, and the second roller 4, thereby accelerating the drying of the towels. When the rotating shaft 5 rotates counterclockwise, the towels pass through the second roller 4 and the first roller 3 and fall into the washing tank 2 for soaking again. This can shorten the time for towel soaking, drying, and transportation, improve the efficiency of towel pretreatment, and thus improve the efficiency of towel detection. The rotation of the first roller 3 and the second roller 4 improves the stability of the vertical movement of the towels.

[0025] Secondly, the exhaust pipe 10 passes through the through groove 30, and the second sleeve 26 can heat the exhaust pipe 10, thereby heating the air inside the exhaust pipe 10. The warm air is then blown onto the towel surface through the transverse seam 19, improving the towel drying efficiency.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
