Description

Technical Field

[0001] The utility model relates to the technical field of pre-shrinking machines, in particular to a pressure roller for a high-strength pre-shrinking machine. Background Art

[0002] During the weaving and dyeing and finishing process, the fabric is subjected to tension and will accumulate a large internal stress. The fabric that has not been pre-shrunk and finished will shrink and deform to a certain extent after washing. For this reason, the fabric needs to be mechanically pre-shrunk to make the fabric shrink, thereby improving the stability of the fabric size and reducing the shrinkage rate. In combination with the existing literature, a new type of pre-shrinking machine pressure roller (CN213203527U) is disclosed. The document provides a sealing part and uses bolts and hand hole covers to seal the hand holes. The structure is simple and easy to operate. The gasket can prevent the bolts from slipping, and the asbestos gasket is used to make the hand hole cover fit tightly with the head plate. It can be seen that at least the following defects are exposed during use:

[0003] 1. At present, when shrinking machines are manufactured, the pressure rollers are usually pre-installed on the frame of the shrinking machines and debugged before leaving the factory. However, when the surface of the pressure rollers is worn after long-term use, it is troublesome, time-consuming and labor-intensive to disassemble, replace or repair them.

[0004] 2. In the literature, when it is necessary to transport steam to the pressure roller body, the steam inlet pipe is connected to the external steam delivery pump. If the connection of the steam inlet pipe is loose or dragged, it may directly affect the steam supply of the steam inlet pipe, resulting in unstable transportation. Therefore, a pressure roller with stable connection and good sealing is required. Utility Model Content

DETAILED DESCRIPTION

[0024] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0025] Example: Figure 1As shown, a pressure roller for a high-strength preshrinking machine includes a pressure roller body 1. The pressure roller body is made of high-quality alloy steel. The high-quality alloy steel has a hot spot with high strength and high hardness, and has good wear resistance and toughness, and is easy to process and heat-treat. The left and right ends of the pressure roller body 1 are respectively provided with a first shaft head 5 and a second shaft head 6. The second shaft head 6 is provided with an air inlet hole 18 inside for easy communication with an external steam delivery pump to provide steam for the pressure roller body 1 so that the steam heat can be transferred to the fabric through the pressure roller body 1.

[0026] like Figure 2-Figure 3 - Figure 4 As shown, a second shaft head 6 is provided at the left end of the pressure roller body 1, and an air inlet 18 is provided inside the second shaft head 6, and the air inlet 18 is communicated with the pressure roller body 1, and the outer end of the connecting block 10 is fixedly connected to the steam delivery pump, and a second flange 19 is provided on the outer side of the inner end of the connecting block 10. When steam is delivered to the pressure roller body 1, when the second shaft head 6 is connected to the connecting block 10, the sealing gasket 13 is first embedded in the slot 12 of the first flange 9, and then the insert block 11 of the second flange 19 is inserted into the slot 12. At this time, the pipeline inside the connecting block 10 is communicated with the air inlet 18, and then the first flange 9 and the second flange 19 are fixed together by six groups of first bolts 14, so that pressure is evenly applied to the sealing gasket 13 while the connection is fixed, so that the connecting block 10 and the second shaft head 6 are in close contact, thereby effectively improving the sealing performance of the steam and preventing steam leakage. At the same time, the stability of the connection can be ensured to avoid loosening of the connection and affecting the steam supply to the air inlet 18.

[0027] like Figure 5 As shown, when installing the pressure roller body 1, the pressure roller body is first placed on the upper ends of the two sets of mounting seats 4, and then the fixed shell 8 of the pressure roller body 1 is slid downward. When the fixed shell 8 slides into the groove of the mounting seat 4, the baffle 17 provided at the inner end of the mounting seat 4 abuts against the inner side of the fixed shell 8, and then the fixed plate 15 is fixed to the outer end of the mounting seat 4 by the second bolt 16, and the baffle 17 and the fixed plate 15 are both provided with grooves, and the inner diameter of the groove is the same as the inner diameter of the fixed shell 8, so that the fixed shell 8 is stably installed in the mounting seat 4 to avoid it from moving left and right. Slide, and then fix the front and rear sides of the fixing shell 8 to the mounting seat 4 by rotating the third bolt 20. When the surface of the pressure roller body 1 is worn after long-term use, the third bolts 20 on the front and rear sides of the mounting seat 4 and the second bolts 16 on the outer side of the fixing plate can be directly removed, and the fixing plate 15 can be removed. Then, the pressure roller body can be taken out from the upper end of the mounting seat 4 for maintenance or replacement, thereby improving maintenance efficiency. At the same time, the lower end of the mounting seat 4 is connected to the upper end of the electric cylinder 3, so that the user can adjust the height of the pressure roller body 1 according to the material thickness of the fabric.

[0028] Working principle: When installing the pressure roller body 1, first place the pressure roller body on the upper ends of the two sets of mounting seats 4, and then slide the fixed shell 8 of the pressure roller body 1 downward to the inside of the groove of the mounting seat 4. At this time, the baffle 17 set at the inner end of the mounting seat 4 abuts against the inner side of the fixed shell 8, and then the fixed plate 15 is fixed to the outer end of the mounting seat 4 by the second bolt 16, and the fixed shell 8 is stably installed inside the mounting seat 4 to prevent it from sliding left and right, and then the front and rear sides of the fixed shell 8 are fixed to the mounting seat 4 by rotating the third bolt 20. When the pressure roller body 1 is worn out after long-term use, the pressure roller body 1 can be taken out from the upper end of the mounting seat 4 for maintenance or replacement. When steam is transported to the pressure roller body 1, the second shaft head 6 is connected to the connecting block 10. First, the sealing gasket 13 is embedded in the slot 12 of the first flange 9, and then the insert block 11 of the second flange 19 is inserted into the slot 12. At this time, the pipe inside the connecting block 10 is connected with the air inlet 18, and then the first flange 9 and the second flange 19 are fixed together by six groups of first bolts 14, so that pressure is evenly applied to the sealing gasket 13 while the connection is fixed, so that the connecting block 10 and the second shaft head 6 are in close contact, thereby effectively improving the sealing performance of the steam and preventing steam leakage. At the same time, the stability of the connection can be ensured to avoid looseness of the connection and affect the steam supply of the air inlet 18. At the same time, the lower end of the mounting seat 4 is connected to the upper end of the electric cylinder 3, so that the user can adjust the height of the pressure roller body 1 according to the material thickness of the fabric.
