Description

Technical Field

[0001] This utility model belongs to the field of fabric processing technology, and specifically relates to a double-sided opening machine. Background Technology

[0002] A tube opening machine is a specialized piece of equipment in the textile industry used to process cylindrical knitted or woven fabrics. Its main function is to unfold cylindrical fabrics into a flat state so that subsequent processing steps such as printing, dyeing, setting, and cutting can be performed, transforming the cylindrical fabric from a double-layered tube into a single-layered flat state.

[0003] Existing double-sided spreading machines allow cylindrical fabric to enter the machine via guide rollers. A motor then drives the connected spreading rollers to rotate, causing the fabric to spread laterally using spiral spreading rollers or belts on both sides during transport. This achieves double-sided spreading of the fabric. However, in actual use, to accommodate the thickness of the fabric to be spread, operators need to manually adjust the distance between the upper and lower spreading rollers. The positions of the rollers are fixed using springs, bolts, and other mechanisms to ensure stable clamping of the fabric. This process is cumbersome, time-consuming, and labor-intensive, requiring a significant amount of time for adjustment and fixing. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a double-sided opening machine, which enables the opening rollers on both the upper and lower sides to quickly and stably adapt to the fabric that needs to be opened and clamp it, so that the opening rollers on both the upper and lower sides can stably open the fabric.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a double-sided opening machine, including a frame, a mounting base on the frame, symmetrically distributed guide rollers rotatably arranged inside the mounting base, multiple guide rails arranged inside the mounting base, a drive seat and a movable seat slidably arranged between the guide rails, symmetrically distributed drive blocks slidably arranged inside the drive seat, a connecting rod rotatably arranged on the upper side of each drive block, symmetrically distributed sliders slidably arranged inside the movable seat, the end of the connecting rod away from the drive block is rotatably connected to an adjacent slider, and the middle of two adjacent sliders is rotatably connected.

[0006] As a further improvement of this utility model, both the drive seat and the movable seat are provided with a spreading mechanism, which is used to spread the fabric. The drive seat is also provided with a drive mechanism, which is used to adjust the distance between the drive seat and the movable seat.

[0007] As a further improvement of this utility model, the drive mechanism includes bidirectional lead screws symmetrically rotatably arranged on both sides inside the drive seat, drive blocks being threadedly connected to adjacent bidirectional lead screws respectively, symmetrically distributed rotating rods being rotatably arranged in the middle of the drive seat, each rotating rod being fixedly fitted with a bevel gear II, symmetrically distributed rotating shafts being rotatably arranged inside the drive seat, each rotating shaft being fixed to adjacent bidirectional lead screws via couplings, each rotating shaft being fixedly fitted with a bevel gear I on its outer side, each bevel gear I meshing with adjacent bevel gear II; a dual-axis motor is arranged in the middle of the drive seat, the output shafts of the dual-axis motor being fixed to adjacent rotating rods via couplings.

[0008] As a further improvement of this utility model, the movable seat is provided with multiple L-shaped seats 1, and each adjacent L-shaped seat 1 is rotatably provided with a spreading roller 1. The drive seat is provided with multiple L-shaped seats 2, and each adjacent L-shaped seat 2 is rotatably provided with a spreading roller 2. Each L-shaped seat 2 on the rear side is provided with a servo motor, and the output shaft of the servo motor is fixed to the adjacent spreading roller 2 by a coupling.

[0009] As a further improvement of this utility model, the mounting base is provided with multiple hydraulic push rods, and the telescopic ends of the hydraulic push rods are all connected and fixed to the drive base; a control box is provided on the outside of the frame, and the servo motor, hydraulic push rods and dual-axis motor are all electrically connected to the control box.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] Firstly, the hydraulic push rod is controlled by the control box, which causes the drive seat to move up or down along with the movable seat via the connecting rod, thereby adjusting the opening height.

[0012] Secondly, the dual-axis motor is controlled by the control box, so that the output shaft of the dual-axis motor drives the rotating rod connected to it to rotate. Through the scissor brace structure composed of the drive block, connecting rod and slider, the movable seat slides with the guide rail, which moves the movable seat closer to the drive seat, and then moves the upper opening roller one closer to the lower opening roller two, so that the fabric to be opened is sandwiched between the opening roller one and the opening roller two.

[0013] Third, the meshing relationship between bevel gear one and bevel gear two drives the bidirectional lead screws on both sides to rotate synchronously. Then, through the threaded relationship between the bidirectional lead screws and the drive block, the drive block moves towards each other or away from each other, which in turn drives the first opening roller to stably approach the second opening roller, thus stably clamping the fabric.

[0014] Fourth, the servo motor is controlled by the control box, so that the output shaft of the servo motor drives the second opening roller connected to it to rotate. Through the cooperation of the second opening roller and the first opening roller, the fabric is opened quickly and stably from the top and bottom. Attached Figure Description

Detailed Implementation

[0021] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0022] like Figure 2 , 4As shown, the device includes a frame 101, on which a mounting base 102 is mounted. Symmetrically distributed guide rollers 112 are rotatably mounted inside the mounting base 102. Multiple guide rails 104 are mounted inside the mounting base 102. A drive seat 105 and a movable seat 106 are slidably mounted between the guide rails 104. Symmetrically distributed drive blocks 201 are slidably mounted inside the drive seat 105. A connecting rod 203 is rotatably mounted on the upper side of each drive block 201. Symmetrically distributed sliders 202 are slidably mounted inside the movable seat 106. The end of the connecting rod 203 away from the drive block 201 is rotatably connected to an adjacent slider 202, and the middle of two adjacent sliders 202 are rotatably connected. Both the drive seat 105 and the movable seat 106 are equipped with a fabric opening mechanism for opening the fabric width. The drive seat 105 is also equipped with a drive mechanism for adjusting the distance between the drive seat 105 and the movable seat 106.

[0023] like Figure 3 , 4 As shown, the drive mechanism includes bidirectional lead screws 209 symmetrically rotatably disposed on both sides inside the drive base 105. The drive block 201 is threadedly connected to the adjacent bidirectional lead screws 209. The drive base 105 has symmetrically distributed rotating rods 206 rotatably disposed in the middle. Each rotating rod 206 is fixedly fitted with a second bevel gear 207. The drive base 105 has symmetrically distributed rotating shafts 204 rotatably disposed inside. Each rotating shaft 204 is fixedly connected to the adjacent bidirectional lead screws 209 by a coupling. Each rotating shaft 204 has a first bevel gear 205 fixedly fitted on its outer side. The first bevel gear 205 meshes with the adjacent second bevel gear 207. The drive base 105 has a dual-axis motor 208 disposed in the middle. The output shaft of the dual-axis motor 208 is fixedly connected to the adjacent rotating rods 206 by a coupling.

[0024] like Figure 2 , 3 As shown, multiple L-shaped seats 107 are provided on the movable seat 106, and a spreading roller 108 is rotatably arranged between adjacent L-shaped seats 107. Multiple L-shaped seats 2 109 are provided on the drive seat 105, and a spreading roller 2 110 is rotatably arranged between adjacent L-shaped seats 2 109. A servo motor 111 is provided on each of the rear L-shaped seats 2 109. The output shaft of the servo motor 111 is fixed to the adjacent spreading roller 2 110 through a coupling.

[0025] like Figure 4 As shown, the mounting base 102 is provided with multiple hydraulic push rods 113, and the telescopic ends of the hydraulic push rods 113 are all connected and fixed to the drive base 105.

[0026] like Figure 1 , 4As shown, a control box 103 is provided on the outside of the frame 101, and the servo motor 111, hydraulic push rod 113 and dual-axis motor 208 are all electrically connected to the control box 103.

[0027] In use, the control box 103 controls the operation of the hydraulic push rod 113, which causes the hydraulic push rod 113 to drive the drive seat 105 to slide between the guide rails 104, thereby causing the drive seat 105 to drive the movable seat 106 to rise or fall together with it through the connecting rod 203, so as to adjust the opening height.

[0028] Then, the control box 103 regulates the operation of the dual-axis motor 208, causing the output shaft of the dual-axis motor 208 to drive the rotating rod 206 connected to it to rotate. Through the meshing relationship between bevel gear 1 205 and bevel gear 207, the two double-headed screws 209 on both sides rotate synchronously. In turn, through the threaded relationship between the double-headed screw 209 and the drive block 201, the drive block 201 is driven to move towards or away from each other. During the movement of the drive block 201: the drive block 201 and the connecting rod Rotation occurs between 203, between connecting rod 203 and slider 202, and between connecting rod 203 and connecting rod 203. Through the scissor brace structure formed by driving block 201, connecting rod 203 and slider 202, the movable seat 106 slides with guide rail 104, causing the movable seat 106 to move closer to driving seat 105, which in turn causes the upper opening roller 108 to move closer to the lower opening roller 210, so that the fabric to be opened is clamped between opening roller 108 and opening roller 210.

[0029] The servo motor 111 is controlled by the control box 103, which causes the output shaft of the servo motor 111 to drive the second opening roller 110 connected to it to rotate. Through the cooperation of the second opening roller 110 and the first opening roller 108, the fabric is opened quickly and stably from the top and bottom.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
