Description

Technical Field

[0001] This utility model relates to the field of tension detection technology, and in particular to a water washing tension detection device. Background Technology

[0002] In the production process of textile fabrics, the conveying tension of the fabric is an important process parameter. Appropriate tension can ensure that the fabric is subjected to uniform force during production and conveying, and avoid problems such as wrinkles, deformation or uneven stretching of the fabric.

[0003] Most current dyeing and printing equipment uses tensioners to detect the conveying tension of the fabric to ensure stability and fabric quality during processing. However, when tensioners are applied to dyeing and printing equipment such as washing machines, the washing machines are generally equipped with high-temperature acidic or alkaline solutions to soak and clean the fabric.

[0004] In order for the tensioner to both detect the tension of the fabric and ensure that the fabric is immersed in the solution for transport, it is sometimes necessary to immerse the tensioner and the fabric in the solution together. However, acidic or alkaline solutions with high temperature are corrosive. Tensioners that are immersed in the solution for a long time are susceptible to corrosion by environmental factors, which can easily affect the tension detection accuracy of the fabric transport and even affect the processing quality of the fabric.

A notch is opened on one side of the housing. An installation cylinder corresponding to the position of the notch is fixed on the support frame. A spring is provided between the end cap and the installation cylinder. A sealing sleeve and a magnet sealed in the sealing sleeve are installed inside the installation cylinder. A fixing ring located outside the sealing sleeve is fixed inside the installation cylinder.

[0008] Preferably, the sealing sleeve has an inner groove for accommodating the magnet, and the inner groove is provided with sealant to fix the magnet.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0025] In the description of this specification, the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or unit referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] like Figures 1-5 As shown, a water washing tension testing device includes a housing 1 and an end cap 2 installed at one end of the housing 1. The end cap 2 closes the upper port of the housing 1. Specifically, fixing caps 13 are fixed on both sides of the housing 1 by welding. The end cap 2 has through holes 22 corresponding to the positions of the fixing caps 13. The end cap 2 is provided with bolts 3 that pass through the through holes 22 and are connected to the fixing caps 13. That is, the bolts 3 are detachably abutted and fixed to the upper end of the housing 1 by means of the bolts 3.

[0027] The housing 1 is provided with a vertically sliding support frame 4, and the housing 1 has a vertically arranged sliding cavity 11. The support frame 4 is spaced within the sliding cavity 11, and the support frame 4 can fit against the inner wall of the housing 1 to achieve vertical sliding displacement within the sliding cavity 11.

[0028] Furthermore, the cross-section of the sliding cavity 11 is square, and the outer contour of the support frame 4 is adapted to the shape of the sliding cavity 11, so that the support frame 4 will not deflect to the left or right during the vertical displacement.

[0029] A notch 12 is provided on one side of the housing 1. A mounting cylinder 5 corresponding to the position of the notch 12 is fixed on the support frame 4. The mounting cylinder 5 is welded and fixed to the support frame 4. A reinforcing plate 41 is provided on the support frame 4 and bent and welded to the outside of the mounting cylinder 5. The reinforcing plate 41 is also welded and fixed to the side of the mounting cylinder 5 so as to enhance the structural strength of the support frame 4 and make the connection with the mounting cylinder 5 more reliable.

[0030] A spring 6 is provided between the end cap 2 and the mounting cylinder 5. Specifically, the end cap 2 is provided with an inwardly extending guide rod 21, and the mounting cylinder 5 is provided with a guide rod 55 corresponding to the guide rod 21. The two ends of the spring 6 are respectively sleeved on the guide rod 21 and the guide rod 55. The mounting cylinder 5 is pressed against the lower end of the housing 1 by the spring 6.

[0031] The mounting cylinder 5 extends outward through the notch 12 at one end. A sealing sleeve 51 and a magnet 52 sealed inside the sealing sleeve 51 are installed inside the mounting cylinder 5. The sealing sleeve 51 is made of polytetrafluoroethylene to isolate the magnet 52 from external acid, alkali and other high-temperature solutions, thus ensuring the reliability of the magnet 52.

[0032] The shell 1, end cap 2, bolt 3, support frame 4, mounting cylinder 5, and spring 6 are made of stainless steel to avoid corrosion from acid and alkali solutions.

[0033] Furthermore, the sealing sleeve 51 has an inner groove 511 for accommodating the magnet 52, and the inner groove 511 is provided with a sealant 53 for fixing the magnet 52. That is, the sealant 53 fixes the magnet 52 in the inner groove 511, and the mounting cylinder 5 is fixed with a fixing ring 54 located outside the sealing sleeve 51, and the inner side of the fixing ring 54 abuts against the sealing sleeve 51.

[0034] refer to Figure 5 As shown, in this embodiment, the conveying rollers 73 and 74 for conveying the fabric 75 are installed at the front and rear positions of the water tank 7. The water tank 7 is provided with a solution 72 for cleaning and processing the fabric 75. The fabric 75 is immersed in the solution 72 during the conveying process.

[0035] Furthermore, a tension roller 71 is rotatably mounted on the fixed ring 54. The conveyed fabric 75 is then wound upwards around the tension roller 71. When the fabric 75 becomes taut due to excessive tension and pulls the tension roller 71 upwards, the tension roller 71 will drive the entire mounting cylinder 5 to move upwards. That is, the magnet 52 moves synchronously and gives an external signal for upward movement. It can also be understood that a magnetic sensor is installed on the outside of the water tank 7. When the magnet 52 moves upwards, it gradually becomes opposite to the inside and outside of the magnetic sensor. At this time, the transmission speed of the conveying roller 74 can be reduced to reduce the tension of the fabric 75, so that the fabric 75 can be more loosely immersed in the solution 72 for conveying. Thus, this embodiment can more accurately adjust the tension of the fabric 75 to ensure the quality of the fabric 75 washing process.

[0036] Furthermore, after conveying the fabric 75 at a certain speed for a certain period of time, the conveying roller 74 returns to its original speed to prevent the fabric 75 from accumulating in the water tank 7. When the fabric 75 is tensioned again and pulls the tension roller 71 and magnet 52 upward, the conveying roller 74 slows down again, so that the conveying of the fabric 75 is kept within a reasonable dynamic range.

[0037] This utility model has a simple structure and reasonable design, and can work for a long time in a corrosive environment without affecting the tension detection effect, making it highly practical.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
