Description

Technical Field

[0001] This utility model relates to the field of cutting machine equipment technology, and in particular to a floating roller mechanism with automatically adjustable counterweight. Background Technology

[0002] In the automotive industry, radial tires are used. The carcass ply and belt ply are the main load-bearing components of a radial tire, enduring extremely complex forces such as cyclic tension, bending, and shearing, forming the tire's load-bearing skeleton. The quality of the carcass ply and belt ply directly affects the tire's performance and quality, ensuring the tire has the necessary strength and dimensional stability. Their strength and elasticity allow the tire to withstand complex stresses and strains during use, mitigating vibrations and impacts from the road surface. Their performance determines the tire's quality and overall performance.

[0003] Currently, cord fabric rolls are cut using a cutting machine. During the cord fabric feeding process, a floating roller maintains stable tension in the cord fabric to ensure its quality. Existing floating rollers adjust their weight by adding or removing counterweights, thereby adjusting the tension on the cord fabric.

[0004] The existing technology has at least the following problems: First, the floating roller cannot automatically adjust the pressure on the fabric. When the material thickness and weight are different, the counterweight needs to be adjusted manually, which is quite troublesome. Second, when feeding the material, the floating roller is at its lowest point, which makes it inconvenient for workers to feed the material. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by developing a floating roller mechanism with automatically adjustable counterweight. This invention not only facilitates the adjustment of the floating roller's pressure on the fabric but also makes it easier to feed the fabric, effectively improving the cutting efficiency and effect of the fabric.

[0006] The technical solution of this utility model to solve the technical problem is as follows: a floating roller mechanism with automatically adjustable counterweight, including two sets of brackets, a floating frame between the two sets of brackets, and rodless cylinders on both sets of brackets. The actuator slider of the rodless cylinder is connected to the end of the floating frame.

[0007] As an optimization, both sets of supports are also equipped with cylindrical shaft tracks, on which linear bearings are mounted and connected to the ends of the floating frame. By setting up cylindrical shaft tracks and linear bearings, the lifting and lowering of the floating frame can be guided, ensuring the stability of the floating frame during lifting and lowering.

[0008] As an optimization, one set of rodless cylinders is positioned on the first side of the first set of supports, and the other set of rodless cylinders is positioned on the second side of the second set of supports. This positions the actuators of the two sets of rodless cylinders diagonally across the floating frame, ensuring even force distribution and maintaining balance during lifting and lowering, thus preventing jamming during ascent and descent.

[0009] As an optimization, one set of cylindrical shaft tracks is positioned on the second side of the first set of supports, and another set of cylindrical shaft tracks is positioned on the first side of the second set of supports. This arrangement, with the two sets of cylindrical shaft tracks and linear bearings positioned diagonally across the floating frame, works in conjunction with rodless cylinders to ensure even force distribution and balance during lifting and lowering, preventing jamming during ascent and descent.

[0010] As an optimization, several sets of rollers are provided on both sides and the bottom of the floating frame. This ensures stable material supply, allows the fabric to pass smoothly, and prevents the fabric from rubbing against the sides of the floating frame.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] By setting up a support bracket, it can be connected to the main body of the cutting machine; by setting up a floating frame, the floating tensioning fabric can be raised and lowered to maintain stable tension and avoid slack or over-tension; by setting up a rodless cylinder, the floating frame can be actively raised and lowered. The air supply pressure to the rodless cylinder can be automatically adjusted according to working conditions, thereby changing the thrust of the actuator slider on the floating frame, replacing the counterweight in generating pressure on the floating frame, thus adjusting the pressure of the floating frame on the fabric. This avoids inaccurate cutting width caused by different material thicknesses and weights, and the floating frame can be raised during material feeding for easier material feeding by the worker. This utility model not only facilitates the adjustment of the floating roller's pressure on the fabric but also facilitates fabric feeding, effectively improving the cutting efficiency and cutting effect of the fabric.

[0016] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0017] Example 1

[0018] Figure 1 As one embodiment of this utility model, such as Figure 1As shown, a floating roller mechanism with automatically adjustable counterweight includes two sets of supports 1 and 2. The tops of the two sets of supports 1 are connected by a crossbar. A floating frame 2 is provided between the two sets of supports 1. A rodless cylinder 3 is provided on each set of supports 1. The actuator slider 4 of the rodless cylinder 3 is connected to the end of the floating frame 2.

[0019] By setting bracket 1, it can be connected to the main body of the cutting machine; by setting floating frame 2, it can raise and lower the floating tension curtain to maintain stable tension of the curtain and avoid slack or excessive tension; by setting rodless cylinder 3, it can actively raise and lower floating frame 2. According to the working conditions, the air supply pressure to rodless cylinder 3 can be adjusted to change the thrust of the actuator slider 4 on floating frame 2, which replaces the counterweight to generate pressure on floating frame 2, thereby adjusting the pressure of floating frame 2 on curtain and avoiding inaccurate cutting width caused by different material thicknesses and weights. Floating frame 2 can also be raised when feeding material to facilitate material feeding by workers.

[0020] Both sets of support brackets 1 are also equipped with cylindrical shaft rails 5, and linear bearings 6 are installed on the cylindrical shaft rails 5. The linear bearings 6 are connected to the ends of the floating frame 2. By setting the cylindrical shaft rails 5 and linear bearings 6, the lifting and lowering of the floating frame 2 can be guided, ensuring the stability of the floating frame 2 during lifting and lowering.

[0021] One set of rodless cylinders 3 is located on the first side of the first set of brackets 1, and another set of rodless cylinders 3 is located on the second side of the second set of brackets 1. This arrangement ensures that the actuator sliders 4 of the two sets of rodless cylinders 3 are positioned diagonally opposite each other on the floating frame 2, resulting in even force distribution on the floating frame 2, maintaining balance during lifting and lowering, and preventing jamming during ascent and descent.

[0022] One set of cylindrical shaft tracks 5 is set on the second side of the first set of supports 1, and another set of cylindrical shaft tracks 5 is set on the first side of the second set of supports 1. This arrangement, with the two sets of cylindrical shaft tracks 5 and linear bearings 6 positioned diagonally on the floating frame 2, works in conjunction with the rodless cylinder 3 to ensure that the floating frame 2 experiences uniform force during lifting and lowering, maintaining balance and preventing jamming during ascent and descent.

[0023] Several sets of rollers 7 are provided on both sides and the bottom of the floating frame 2. They can stably supply material, allowing the curtain to pass smoothly and preventing the curtain from rubbing against the sides of the floating frame 2.

[0024] like Figure 2As shown, during use, the bottom of the rodless cylinder 3 is connected to the first output port of the solenoid valve 8 through the first air passage, and the top of the rodless cylinder 3 is connected to the second output port of the solenoid valve 8 through the second air passage. The air inlet of the solenoid valve 8 is connected to the main air passage. The solenoid valve 8 is a three-position five-way center-sealed solenoid valve. Both the first and second air passages are equipped with proportional regulating valves 9. During material feeding, one end of the solenoid valve 8 is energized, connecting the first air path to the main air path. The proportional regulating valve 9 in the first air path adjusts the pressure, causing the rodless cylinder 3 to push the actuator slider 4 upward, thereby raising the floating frame 2. At this time, the worker can feed the material. During material feeding, if it is necessary to reduce the pressure of the floating frame 2 on the curtain, one end of the solenoid valve 8 is energized, connecting the first air path to the main air path. The proportional regulating valve 9 in the first and second air paths adjusts the air pressure according to the set parameters, causing the rodless cylinder 3 to push the actuator slider 4 upward. The actuator slider 4, together with the curtain, supports the weight of the floating frame 2, thus reducing the pressure on the curtain and producing a weight reduction effect. If it is necessary to increase the downward pressure of the floating frame 2 on the curtain, the other end of the solenoid valve 8 is energized, connecting the second air path to the main air path. The proportional regulating valve 9 in the first and second air paths adjusts the air pressure according to the set parameters, causing the rodless cylinder 3 to press down the actuator slider 4. Together with the weight of the floating frame 2, the pressure on the curtain is increased, thus producing a weight increase effect. This invention allows for convenient adjustment of the pressure of the floating roller on the fabric and facilitates the feeding of the fabric, effectively improving the cutting efficiency and effect of the fabric.
