Abstract
Description
Technical Field
[0001] This utility model relates to the field of umbrella flower production technology, and in particular to a feeding structure for folding umbrella flowers. Background Technology
[0002] The umbrella pleat is a waterproof component connecting the top center of the umbrella canopy to the handle. It is typically made of circular pleated fabric, folded by hand or machine, as shown in the attached image. Figure 5 Because of the petal-like shape of the fabric, the fabric tends to stick together when the fabric is stacked together during the mechanical umbrella folding process. Therefore, when using a vacuum suction cup for feeding during the automated umbrella folding process, the vacuum suction cup can easily suck up multiple fabrics at the same time and feed them into the umbrella folding mechanism, causing poor folding or even clogging the umbrella folding mechanism, making the umbrella folding device unable to function properly. Summary of the Invention
[0003] The purpose of this utility model is to provide a feeding structure for folding umbrella fabric, which aims to solve the problem that the existing folding umbrella fabric mechanism can easily attract multiple umbrella fabrics at the same time using a vacuum suction cup, resulting in poor feeding.
[0004] To address this, the present invention provides the following technical solution: a feeding structure for a folding umbrella fabric, comprising a base and a suction cup. The suction cup includes a rotating end and an adsorption end. The rotating end is connected to a servo motor for its rotation. The adsorption end is an annular disc with several adsorption ports on its lower annular surface. These adsorption ports are connected to an external vacuum extraction device through connecting holes inside the suction cup. The base is provided with a feeding rod and a folding umbrella fabric mechanism in the rotation direction of the adsorption end. The feeding rod is vertically adjustable on the base. The folding umbrella fabric mechanism includes an embossing surface. The lower annular surface of the adsorption end is higher than the embossing surface. The base is provided with a negative pressure sensor connected to the connecting holes. The servo motor controls the rotation of the suction cup. When the suction cup rotates above the feeding rod, the feeding rod lifts the umbrella fabric to below the adsorption end. The suction cup adsorbs the umbrella fabric through the adsorption ports. The servo motor rotates the suction cup, causing the adsorption end to rotate onto the embossing surface of the folding umbrella fabric mechanism.
[0005] Furthermore, the base is equipped with a control panel. The control panel can be used to set the positioning parameters for the servo motor to rotate the suction cup between the feeding rod and the folding umbrella mechanism, and can also set the control parameters for the negative pressure sensor. When the negative pressure sensor detects that the vacuum degree at the suction port has reached the set value, the negative pressure sensor controls the rising height of the feeding rod through the controller.
[0006] Furthermore, the suction end is provided with an annular notch. After the suction end of the suction cup adsorbs the umbrella fabric, the notch allows for easy manual removal of the umbrella fabric stuck under the suction cup.
[0007] Furthermore, a push rod is provided on one side of the suction end, and the lower bottom surface of the push rod is flush with the embossed surface. When the suction end of the suction cup rotates from the feeding rod to the umbrella folding mechanism, the lower bottom surface of the push rod adheres to the embossed surface and pushes the folded umbrella flower away from the surface of the embossed surface, thereby facilitating the folding of new umbrella flower fabric.
[0008] Furthermore, the push rod has a rounded front surface. By setting the front surface to be rounded, the push rod can better control the path of pushing the umbrella flower away from the embossed surface when rotating and pushing it.
[0009] Furthermore, the machine base is equipped with a feed hopper located in the direction of rotation of the push rod. After the umbrella fabric is folded by the umbrella folding device, it is pushed by the push rod and then guided and collected through the feed hopper.
[0010] This invention utilizes multiple suction ports connected to a vacuum extraction device to adsorb umbrella fabric, ensuring that the suction cups can evenly adsorb the umbrella fabric and that the umbrella fabric is subjected to uniform force. By controlling the maximum vacuum degree of adsorption on the suction cups, the force of adsorption of the umbrella fabric is controllable, preventing the umbrella fabric from being pulled up by the lower layer of umbrella fabric due to excessive adsorption force or uneven adsorption.
[0011] This invention utilizes a liftable feeding rod. As the feeding rod rises, the umbrella fabric on it presses against the suction cup. Once the umbrella fabric is pressed against the suction cup, it covers the suction port, increasing the vacuum level sensed by the negative pressure sensor. When the feeding rod rises to a certain height and the vacuum level sensed by the negative pressure sensor reaches a set value, the negative pressure sensor can control the feeding rod to stop rising and begin to descend to its initial position via a controller. This achieves the suction cup's adsorption of the umbrella fabric and enables rapid separation between the upper and lower layers of umbrella fabric. Attached Figure Description

Detailed Implementation
[0018] The embodiments of this utility model will be briefly described below with reference to the accompanying drawings.
[0019] A feeding structure for a folding umbrella flower, referring to Figures 1-4 The device includes a base 1 and a suction cup 3. The suction cup 3 includes a rotating end 31 and an adsorption end 32. The rotating end 31 has a shaft hole 311 at its center and multiple fixing holes 312 surrounding the shaft hole 311. The fixing holes 312 are connected to the connecting plate 41 of the servo motor 4 by screws. The connecting plate 41 of the servo motor 4 is fixedly connected to the power output shaft of the servo motor 4. The adsorption end 32 is an annular disc with several adsorption ports 321 on its lower annular surface. The multiple adsorption ports 321 are connected to an external vacuum extraction device inside the suction cup 3 through connecting holes 34 for better operation. An annular notch 322 is provided on the suction end 32. After the suction end 32 of the suction cup 3 adsorbs the umbrella fabric 7, the notch 322 allows for easy manual removal of the umbrella fabric 7 stuck under the suction cup 3. The machine base 1 is provided with a feeding rod 2 and an umbrella folding mechanism 8 in the rotation direction of the suction end 32. The feeding rod 2 can be raised and lowered on the machine base 1. The umbrella folding mechanism 8 is used to fold the umbrella fabric 7 into an umbrella shape. The umbrella folding mechanism 8 includes an embossing surface 81, which is used to receive the umbrella fabric 7. The lower annular surface of the suction end 32 is higher than the embossing surface 81. The umbrella folding mechanism 8 folds the umbrella fabric 7 into the shape shown in the attached figure. Figure 5 The umbrella pattern shown is created by folding the umbrella fabric 7 using the folding mechanism 8. Figure 5 The process and principle of the umbrella flower shown are not covered in detail in this embodiment because they are not within the scope of protection of this patent.
[0020] The machine base 1 is equipped with a negative pressure sensor 5 connected to the connecting hole 34, which allows the negative pressure sensor 5 to sense the vacuum level of the suction port 321 of the suction cup 3. The servo motor 4 controls the rotation of the suction cup 3. When the suction cup 3 rotates above the feeding rod 2, the feeding rod 2 lifts the umbrella fabric 7 to below the suction end 32. The suction cup 3 adsorbs the umbrella fabric 7 through the suction port 321. The servo motor 4 rotates the suction cup 3, causing the suction end 32 to rotate onto the embossing surface 81 of the umbrella folding mechanism 8. The suction cup 3 releases and positions the adsorbed umbrella fabric 7 at the center of the embossing surface 81 of the umbrella folding mechanism 8. At the same time, a push rod 33 is also provided on one side of the suction end 32, with the lower bottom surface of the push rod 33 flush with the embossing surface 81. When the suction end 32 rotates to the embossing surface 81 of the umbrella flower mechanism 8, the push rod 33 on one side can simultaneously push the formed umbrella flower on the embossing surface 81. In the process of the suction cup 3 rotating from the center of the embossing surface 81 to the feeding rod 2, the umbrella flower is pushed out. Of course, in order to better ensure that the umbrella flower on the embossing surface 81 moves in the rotation direction of the push rod 33, the front end surface of the push rod 32 is set to be arc-shaped. The arc shape can fit the shape of the umbrella flower. The arc-shaped push rod 33 can better control the path of pushing the umbrella flower away from the embossing surface 81. The base 1 is provided with a feeding hopper 6 in the rotation direction of the push rod 33. After the umbrella flower is pushed by the push rod 33, it is guided and collected by the feeding hopper 6.
[0021] In this embodiment, the base 1 is equipped with a control panel 11. The control panel 11 can be used to set the positioning parameters for the rotation of the servo motor 4, thereby positioning the servo motor 4 to rotate the suction cup 3 between the feeding rod 2 and the umbrella flower mechanism 8. The control panel 11 can also set the control parameters for the negative pressure sensor 5. When the negative pressure sensor 5 senses that the vacuum degree of the suction port 321 has reached the set value, the negative pressure sensor 5 controls the feeding rod 2 to rise through the controller. As the feeding rod 2 rises, the umbrella flower cloth 7 on the feeding rod 2 presses against the bottom of the suction cup 3. After the umbrella flower cloth 7 presses against the bottom of the suction cup 3, the umbrella flower cloth 7 will... The cover of the port 321 increases the vacuum level sensed by the negative pressure sensor 5. When the feeding rod 2 rises to a certain height, and the vacuum level sensed by the negative pressure sensor 5 reaches the set value, the negative pressure sensor 5 can control the feeding rod 2 to stop rising and start falling back to the initial position through the controller. This realizes the adsorption of the umbrella fabric 7 by the suction cup 3 and realizes the rapid separation between the upper umbrella fabric 7 and the lower umbrella fabric 7. In this embodiment, the rising mechanism of the feeding rod 2 can adopt the structure of the prior art, such as the feeding rod 2 rising by a cylinder or by a lifting motor.
[0022] The above embodiments merely illustrate the implementation of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
