[0037] The present application provides a Y-axis cantilever structure of a film making and dyeing machine.

[0038] like Figures 1 to 6 As shown, in one embodiment of the present application,

[0039] like Figure 1 Shown is a Y-axis cantilever structure of a film making and dyeing machine, comprising a Y-axis cantilever connecting base plate 1, a rotating drive device 2, a transmission device 3, a Y-axis drag chain 4 and a positioning device 5.

[0040] The Y-axis cantilever connection base plate 1 is the motion support base plate of the Y-axis, and the power input, transmission and power output of the entire Y-axis are all arranged in the Y-axis cantilever connection base plate 1.

[0041] like Figure 2-Figure 5 As shown: the rotary drive device 2 of the utility model is arranged on the Y-axis cantilever connecting base plate 1, and the rotary drive device 2 includes a motor mounting plate 21 and a drive motor 22. A conveyor belt 23 is connected to the main shaft of the drive motor 22. The drive motor 22 is generally a stepper motor, which provides power for the entire device and drives other devices through the conveyor belt 23.

[0042] The motor mounting plate 21 includes a vertical plate 211 and a supporting plate 212. A through hole 213 is provided on the supporting plate 212. The main shaft of the driving motor 22 is located in the through hole 213. The driving motor 22 is inverted and fixed on the supporting plate 212. The main shaft of the driving motor 22 is inserted into the through hole 213, and the conveyor belt 23 is connected to the end of the main shaft.

[0043] In order to reduce the friction of the conveyor belt 23, a driving wheel 221 is sleeved on the main shaft of the driving motor 22, and a driven wheel mounting seat 24 is also provided on the Y-axis cantilever connecting base plate 1, and a driven wheel 241 is sleeved on the driven wheel mounting seat 24. One end of the conveyor belt 23 is sleeved on the driving wheel 221, and the other end of the conveyor belt 23 is sleeved on the driven wheel 241.

[0044] In order to improve the transmission accuracy of the conveyor belt 23, gears are provided on the driving wheel 221 and the driven wheel 241, and the conveyor belt 23 is a synchronous belt.

[0045] like Figure 2-4 As shown: The main improvement of the utility model lies in the transmission device 3. Specifically, the transmission device 3 includes a connecting plate 31, a conveyor belt connecting device 32 is provided at the upper end of the connecting plate 31, and a guide device 33 is provided at the lower end of the connecting plate 31; the conveyor belt connecting device 32 connects part of the entire transmission device 3 with the conveyor belt, and converts the movement of the conveyor belt 23 into the movement of the connecting plate 31.

[0046] like Figure 3-5 As shown: the conveyor belt connecting device 32 includes a conveyor belt fixed connecting seat 321 and a conveyor belt pressure plate 322. The conveyor belt fixed connecting seat 321 is fixed on the upper surface of the connecting plate 31. The conveyor belt fixed connecting seat 321 is provided with a connecting slot 320. The conveyor belt pressure plate 322 clamps part of the conveyor belt 23 in the connecting slot 320.

[0047] like Figure 3-6 As shown: Another major improvement of the utility model is that a guide device 33 is provided. Specifically, the guide device 33 includes a linear guide rail 331 and a guide slider 332. The guide slider 332 slides along the direction of the linear guide rail 331, and the top of the guide slider 332 is fixedly connected to the connecting plate 31.

[0048] The linear guide rail 331 in the guide device 33 is directly mounted on the Y-axis cantilever connecting base plate 1, and then the weight of the connecting plate 31 is carried by the guide slider 332, so that the movement of the connecting plate 31 only needs to overcome the sliding friction. Therefore, the conveyor belt 23 can easily drive the movement of the entire connecting plate 31, and the radial path of the rotation of the driving wheel 221 of the driving motor 22 and the moving distance of the conveyor belt 23 can be kept the same, thereby achieving the purpose of precise control.

[0049] The Y-axis cantilever connecting base plate 1, the motor mounting plate 21 and the guide device 33 are all made of aluminum alloy. The above structure is made of aluminum alloy material to improve the mechanical strength and rigidity, ensure the stability under high-speed and high-precision operation, and the structure is easy to install, easy to maintain and has a long service life.

[0050] The Y-axis drag chain 4 of the utility model serves as a connecting element with an external manipulator. The lower end of the Y-axis drag chain 4 is fixed to the Y-axis cantilever connecting base plate 1, and the upper end of the Y-axis drag chain 4 is fixed to the connecting plate 31. The driving motor 22 rotates, and the driving conveyor belt 23 rotates, so that the connecting plate 31 moves along the guide device 33, and at the same time drives the Y-axis drag chain 4 to move. A Y-axis drag chain connecting plate 34 is also provided on the connecting plate 31. One end of the Y-axis drag chain connecting plate 34 is connected to the connecting plate 31, and the other end of the Y-axis drag chain connecting plate 34 is connected to the upper end of the Y-axis drag chain 4.

[0051] In order to further accurately control the entire device, a positioning device 5 capable of positioning the zero point is provided, comprising a positioning baffle 51 and a position detection sensor 52 . The positioning baffle 51 is fixed on the guide device 33 , and the position detection sensor 52 is fixed on the connecting plate 31 .

[0052] Specifically, the position detection sensor 52 is a slot-type photoelectric switch, and the position detection sensor 52 is fixed on the Y-axis drag chain connecting plate 34. The position detection sensor 52 and the upper end of the Y-axis drag chain 4 are in the same plane in the length direction of the Y-axis cantilever connecting base plate 1. The positioning baffle 51 is fixed to the end of the linear guide 331, and the position detection sensor 52 sets the end of the linear guide 331 as the starting zero point.

[0053] When each batch of inspection begins or the specified time interval is reached, or the machine is started: the drive motor 22 drives the conveyor belt 23 to move the connecting plate 31 toward the drive motor 22. At the same time, after the position detection sensor 52 is blocked by the positioning baffle 51, the position detection sensor 52 sends a zero position signal to the slide making and dyeing machine controller, which sets the position as the zero point of the Y axis, and then other operating tasks of the slide making and dyeing machine can be performed.

[0054] The slot-type photoelectric switch and positioning baffle can be set to reposition the zero point of the Y-axis direction at any time to prevent the transmission belt from offset due to errors after repeated use. Repositioning can ensure the accuracy of the Y-axis drag chain.

[0055] Working principle: The conveyor belt is driven by a motor, and then the movement of the conveyor belt is converted into the movement of the Y-axis drag chain through the connecting plate in the transmission device. The transmission device is guided by linear guides and guide sliders. The sliding fit takes over most of the transmission resistance, and converts the weight resistance originally required for direct drive into sliding friction. It not only reduces the output torque of the driving power, reduces the deformation and transmission error of the transmission belt, and avoids the error caused by weight and vibration, but also can improve the accuracy of the Y-axis drag chain transmission, and improve the quality and efficiency of film production and dyeing.

[0056] The technical features of the above embodiments can be combined arbitrarily, and the execution order of each method step is not limited. In order to make the description concise, all possible combinations of the technical features in the above embodiments are not described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. The above-mentioned embodiments only express several implementation methods of the present application, and their descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of this application. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the present application, several deformations and improvements can be made, which all belong to the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the attached claims.
