Description

Technical Field

[0001] The utility model relates to the technical field of fabric textiles, in particular to a fabric tensioning force regulating mechanism. Background Art

[0002] In the textile industry, cloth dyeing generally adopts assembly line operation to maximize work efficiency. The process includes: pre-treatment (stain removal), dyeing, post-treatment (removal of floating color), winding, and packaging. During the assembly line operation, the fabric needs to be processed by different mechanical equipment. Due to the differences in the power mechanisms of the mechanical equipment, the transmission speed of the fabric in different mechanical equipment will deviate, resulting in different tension forces of the fabric at different positions. The fabric will fold at the position with small tension force, thus affecting the quality of the fabric. Therefore, a tension adjustment mechanism is needed to adjust the tension force of the fabric.

[0003] Chinese patent document CN212075858U discloses a fabric tension adjustment mechanism. During fabric processing, rollers lift the fabric upward. When the fabric tension is small and does not meet the requirements of streamlined operation, the cylinder is started to move the roller upward for a distance. The roller drives the fabric to move, thereby tensioning the fabric and solving the problem of easy folding of the fabric.

[0004] The existing technology has the following problems:

[0005] At present, the adjustment of fabric tension only relies on manual operation by operators, which is time-consuming and labor-intensive, and is not convenient for adjusting the tension of textile fabrics of different thicknesses. It has certain limitations and is difficult to meet the processing needs of textile fabrics, thereby failing to meet market demand. Utility Model Content

DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] like Figure 1-Figure 6As shown, a fabric tension adjustment mechanism comprises a frame 1, two guide rollers 2 are rotatably connected between opposite sides of the frame 1, a tension adjustment mechanism 3 is rotatably connected to the rear side of the bottom upper surface of the frame 1, a pushing assembly 4 is arranged above the guide roller 2, the pushing assembly 4 comprises two adjustment frames 44 and a connecting plate 45, the tension adjustment mechanism 3 comprises two screw rods 31, the lower ends of the two screw rods 31 are rotatably connected to the left and right sides of the rear side of the bottom upper surface of the frame 1, and support plates 36 are fixedly installed on the left and right sides of the top upper surface of the frame 1. A motor 35 is fixedly installed on the upper surface of the plate 36, and a gear 2 310 is fixedly installed on the output end of the motor 35 through the support plate 36. A gear 1 34 is fixedly installed on the upper end of the screw rod 31 through the frame 1, and the left side of the gear 1 34 is meshed with the right side of the gear 2 310. A screw sleeve 32 is threadedly connected to the outer surface of the screw rod 31, and the right side of the screw sleeve 32 is fixedly installed to the left side of the adjustment frame 44. A guide roller 2 312 is rotatably connected to the lower position of the opposite side of the two adjustment frames 44, and a guide roller 3 41 is rotatably connected to the opposite side of the two connecting plates 45.

[0027] By adjusting the distance between guide roller three 41 and guide roller two 312, it is suitable for adjusting the tension of fabrics of different thicknesses. When conveying, the fabric passes through the upper surface of guide roller one 2 and the distance between guide roller three 41 and guide roller two 312. When it is necessary to adjust the tension of the fabric, the guide roller two 312 is moved upward for a distance through the motor 35, gear two 310, gear one 34, screw 31, and screw sleeve 32, so as to adjust the distance between guide roller two 312 and guide roller one 2. Guide roller two 312 drives the fabric to move, so that the fabric is tensioned, and the adjustment of the tension of the fabric can be completed. The support plate 36 is provided to support the motor 35.

[0028] like Figure 2-Figure 5 As shown, both ends of guide roller 2 312 and guide roller 1 2 are fixedly mounted with limit plates 311.

[0029] The limiting plate 311 has a limiting effect on the fabric.

[0030] like Figure 2-Figure 5 As shown, a strip groove 38 is provided at the rear positions of the left and right sides of the frame 1, and a T-shaped slider 39 is fixedly installed on the left side of the screw sleeve 32, and one side of the slider 39 is slidably connected to the inner surface of the strip groove 38.

[0031] Through the cooperation between the slider 1 39 and the strip groove 1 38 , the guide roller 2 312 moves up and down to prevent the screw sleeve 32 from rotating.

[0032] like Figure 2 , Figure 3As shown, telescopic tubes 33 are fixedly installed on the upper and lower surfaces of the screw sleeve 32, and the telescopic tubes 33 are sleeved on the outer surface of the screw rod 31, and the separated ends of the two telescopic tubes 33 are fixedly installed on the opposite sides of the frame 1 respectively.

[0033] The telescopic tube 33 has a dust-proof effect on the screw rod 31 , thereby preventing dust from adhering to the screw rod 31 and affecting the transmission between the screw rod 31 and the screw sleeve 32 .

[0034] like Figure 3 As shown, a plurality of insertion holes 5 are provided on the left and right sides of the rear side of the frame 1, and an insertion rod 37 passing through a slider 39 is inserted into the inner surface of the insertion hole 5.

[0035] The insert rod 37 is inserted into the insert hole 5 to fix the slider 39 and the frame 1, thereby limiting the screw sleeve 32.

[0036] like Figure 5 , Figure 6 As shown, a multi-stage electric push rod 42 is fixedly installed on the upper surface of the adjustment frame 44 , and the output end of the multi-stage electric push rod 42 passes through the adjustment frame 44 and the upper surface of the connecting plate 45 and is fixedly installed.

[0037] The connecting plate 45 is driven to move up and down by the extension and retraction of the multi-stage electric push rod 42, thereby driving the guide roller three 41 to move up and down, and adjusting the distance between the guide roller three 41 and the guide roller two 312, so as to be suitable for adjusting the tension of fabrics of different thicknesses, reduce limitations, meet the processing needs of textile fabrics, and thus meet market demand.

[0038] like Figure 5 , Figure 6 As shown, a T-shaped slider 43 is fixedly installed on the front and rear sides of the connecting plate 45 , and a strip groove 46 is opened at the upper position of the front and rear sides of the adjusting frame 44 , and the inner surface of the strip groove 46 is slidably connected to one side of the slider 43 .

[0039] The cooperation between the slider 2 43 and the strip groove 2 46 enables the guide roller 3 41 to move stably.

[0040] The working principle of the present invention is as follows: the connecting plate 45 is driven to move up and down by the extension and contraction of the multi-stage electric push rod 42, thereby driving the guide roller three 41 to move up and down, adjusting the distance between the guide roller three 41 and the guide roller two 312, and the fabric passes through the upper surface of the guide roller one 2 and the distance between the guide roller three 41 and the guide roller two 312 during transportation. When the tension of the fabric needs to be adjusted, the guide roller two 312 is moved upward for a distance by the motor 35, the gear two 310, the gear one 34, the screw 31, the screw sleeve 32, and the slider one 39, and then the insertion rod 37 is inserted into the insertion hole 5 to fix the slider one 39 and the frame 1, thereby adjusting the distance between the guide roller two 312 and the guide roller one 2, and the guide roller two 312 drives the fabric to move, so that the fabric is tensioned, and the adjustment of the fabric tension can be completed.

[0041] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
