Description

Technical Field

[0001] This application relates to the field of die-cutting molds, and in particular to an automatic feeding mechanism for a cotton-applying machine. Background Technology

[0002] Flat die-cutting molds are commonly used tools in the packaging industry. They are equipped with blades that cut or crease packaging materials to meet usage requirements.

[0003] Typically, elastic material, known as PVC foam, is also provided on the cutting template on both sides of the blade. This elastic material adheres to the cutting template and is located on both sides of the blade, with the top of the elastic material higher than the blade. Thus, the blade is encased within the elastic material, and only becomes exposed when the elastic material is compressed during cutting. This design serves two purposes: first, after cutting the packaging material, the compressed elastic material returns to its original position, lifting the packaging material and detaching it from the blade; second, it protects the blade, minimizing damage from impacts during non-working periods.

[0004] In existing technologies, the adhesive strips are often cut to a set length manually and then manually pasted onto the die template. However, this method is inefficient and makes it difficult to improve the automation level of production.

[0005] The applicant believes it is necessary to optimize the feeding process of the cotton-applying machine and the automatic feeding mechanism of the cotton-applying machine to automate the picking, feeding and cutting of the cotton, which will help improve the automation level of the cotton-applying machine and increase production efficiency.

[0037] like Figures 1 to 8 As shown, an embodiment of this application provides an automatic feeding mechanism for a cotton-applying machine, which includes:

[0038] The frame 1 has a feeding device 2 for conveying the cotton batting at one end and a feeding area 3 for placing the cotton batting at the other end.

[0039] The feeding device 2 includes a feeding track 21 arranged along the Y-axis direction, and a robotic arm 9 that feeds along the X-axis and Z-axis directions is provided above the frame 1. The robotic arm 9 is equipped with a picking device 4, which picks up the cotton from the feeding area 3 and places it on the feeding track 21.

[0040] In this embodiment, one or more feeding areas 3 can be set. When there are multiple feeding areas 3, they are set sequentially, and all feeding areas 3 are within the stroke of the robotic arm 9.

[0041] The material handling device 4 includes a material handling base plate 41, and at least one set of vertically movable longitudinal pins 42, at least one set of vertically movable pressure heads 43 and at least one set of vertically movable punches 44 are arranged downward above the material handling base plate 41.

[0042] The material receiving base plate 41 is provided with clearance holes 45 corresponding to the longitudinal insert pin 42, pressure head 43 and punch 44.

[0043] In this embodiment, there are 4 longitudinal inserts 42, 2 pressure heads 43, and 2 punches 44.

[0044] As a further improvement of this utility model, the longitudinal insert 42, the pressure head 43 and the punch 44 are not located on the same straight line in the same Y-axis direction.

[0045] In this embodiment, the padding material placed in the feeding area 3 is a stacked block padding material 5. The block padding material 5 has been divided into several padding strips according to a set size. There are connection points between adjacent padding strips. The punch 44 is set to correspond to the connection points. The connection points are cut by the punch 44, thereby separating the connected padding strips.

[0046] In this embodiment, the length and hardness of the cotton strip are variable, the width of the cotton strip is adjustable, and the width of the feeding track 21 is also adjustable.

[0047] After the punch 44 cuts the connection point, the pressure head 43 descends and presses down on the adjacent cotton strip to fix it in place. Before the punch 44 cuts the connection point, the longitudinal pin 42 passes through the picking base plate 41 and inserts into the cotton strip to be picked up. After the picking base plate 41 leaves the feeding area 3, the pressure head 43 rises back above the picking base plate 41.

[0048] It also includes a first cylinder 46, which is disposed on the material picking base plate 41. The cylinder shaft of the first cylinder 46 is arranged downward, and the longitudinal needle 42 is fixed downward on the cylinder shaft of the first cylinder 46. The first cylinder 46 controls the raising and lowering of the longitudinal needle 42. When picking up the cotton strip in the material picking area, the longitudinal needle 42 passes through the material picking base plate 41 and inserts into the cotton strip; when the cotton strip is placed on the feeding track 21, the longitudinal needle 42 rises back above the material picking base plate 41 and disengages from the cotton strip.

[0049] It also includes a second cylinder 47, which is disposed on the material-receiving base plate 41. The cylinder shaft of the second cylinder 47 is arranged downward, and the pressure head is fixed on the cylinder shaft of the second cylinder 47. After the longitudinal insertion pin 42 is inserted into the strip to be picked up, and after the punch 44 has cut off the connection point between the strip to be picked up and the adjacent strip, the pressure head 43 descends under the drive of the second cylinder 47 until the pressure head presses on another strip connected to the strip to be picked up. The material-receiving base plate 41 rises away from the feeding area 3, and the pressure head returns above the material-receiving base plate 41 under the drive of the second cylinder 47.

[0050] It also includes a third cylinder 48, which is mounted on the material-picking base plate 41. The cylinder axis of the third cylinder 48 is oriented downwards, and the punch 44 is fixedly connected to the cylinder axis of the third cylinder 48. The punch 44 cuts the connection point between the cotton strip to be picked up and the connected cotton strip. When there are multiple connection points, multiple punches 44 can be provided accordingly. In other embodiments, only one punch 44 with a length sufficient to cover multiple connection points can be provided, or a punch 44 capable of horizontal movement can be provided.

[0051] Since the longitudinal pin 42 corresponds to the strip to be picked up, the pressure head 43 corresponds to another strip connected to the strip to be picked up, and the punch 44 corresponds to the connection point between the two strips, the longitudinal pin 42, the pressure head 43, and the punch 44 are all set from top to bottom. Therefore, the longitudinal pin 42, the pressure head 43, and the punch 44 are not located on the same straight line in the same Y-axis direction. This arrangement will prevent them from interfering with each other.

[0052] In this embodiment, the vertical pin 42 and the horizontal pin 25 have the same structure, except that the vertical pin 42 is set vertically and the horizontal pin 25 is set horizontally.

[0053] The feeding device 2 includes the feeding track 21. A feeding belt 23 driven by a first motor 22 is provided on the frame 1 corresponding to the feeding track 21. The feeding belt 23 is arranged parallel to the feeding track 21. A fourth cylinder 24 is fixed on the feeding track 21. The cylinder shaft of the fourth cylinder 24 faces the feeding track 21. A transverse pin 25 is fixed on the cylinder shaft of the fourth cylinder 24 facing the feeding track 21. When the picking device 4 places the cotton strip on the feeding track 21, the longitudinal pin 42 is still inserted in the cotton strip. The transverse pin 25 is inserted into the cotton strip under the drive of the fourth cylinder 24. At this time, the longitudinal pin 42 is withdrawn from the cotton strip. The first motor 22 rotates, thereby driving the cotton strip to move back and forth along the Y-axis direction through the transverse pin 25.

[0054] At the end of the feeding track 21, a baffle 26 is provided corresponding to the transverse insert 25. The lower end face of the baffle 26 is higher than the transverse insert 25, and lower than the top of the adhesive strip placed on the feeding track 21. In other embodiments, the baffle 26 can be other structures, as long as it can provide support when the transverse insert 25 is withdrawn from the adhesive strip, so as to facilitate the separation of the transverse insert 25 from the adhesive strip.

[0055] It also includes a cutting mechanism 6, which includes a fifth cylinder 61 fixed to the frame 1. The cylinder shaft of the fifth cylinder 61 is positioned downwards corresponding to the front end of the feeding track 21, and a cutter 62 is provided at the end of the cylinder shaft. The transverse pin 25 drives the cotton strip forward. When the cotton strip passes directly below the cutter 62 to a preset length, the first motor 22 stops rotating, and the cutter 62 cuts the cotton strip. The picking mechanism of the cotton applicator picks up the cut cotton strip and takes it away. The first motor 22 and the cutter 62 continue to work until only tail material remains on the cotton strip on the transverse pin 25. The tail material is the excess material that does not meet the required length and needs to be unloaded from the transverse pin 25 and pushed away from the feeding track 21. The first motor 22 reverses, and the transverse pin 25 brings the tail material back to the end of the feeding track 21 until the transverse pin 25 is blocked by the baffle 26. The fourth cylinder 24 drives the transverse pin 25 to be pulled out of the tail material. The first motor 22 rotates forward and drives the transverse pin 25 to move to the front end of the tail material. The transverse pin 25 extends and is located at the front end of the tail material. The first motor 22 reverses and drives the transverse pin 25 to push the tail material away from the end of the feeding track 21.

[0056] Sensors 7 for detecting whether there is cotton strips are attached are provided at the front and end of the feeding track 21 and on the picking base plate 41. The sensor 7 at the end of the feeding track 21 is used to detect whether the tail material is pushed away from the feeding track 21, the sensor 7 at the front of the feeding track 21 is used to detect whether cotton strips are being conveyed for cutting, and the sensor 7 on the base plate is used to detect whether cotton strips are being picked up.

[0057] A clamping mechanism 8, which can move back and forth in the Y-axis direction, is provided at the front end of the feeding track 21 for clamping and cutting the cotton. The clamping mechanism 8 has been disclosed in a previous patent application and will not be described in detail in this application.

[0058] In implementation, the robotic arm 9 moves to the feeding area 3 and descends to pick up a strip of adhesive tape until the picking base plate 41 is above the strip of adhesive tape to be picked up. The longitudinal pin 42 passes through the picking base plate 41 and inserts into the strip of adhesive tape to be picked up. The punch 44 descends and cuts the connection point between two strips of adhesive tape. The pressure head 43 descends and presses down another strip of adhesive tape adjacent to the strip of adhesive tape to be picked up. The picking base plate 41 rises and the pressure head 43 retracts above the picking base plate 41, completing the process of picking up material from the feeding area 3.

[0059] The robotic arm 9 places the cotton strip onto the feeding track 21. At this time, the longitudinal pin 42 is still inserted into the cotton strip, and the transverse pin 25 is inserted into the cotton strip under the drive of the fourth cylinder 24. At this time, the longitudinal pin 42 is withdrawn from the cotton strip. The first motor 22 rotates forward, thereby driving the cotton strip to move forward along the Y-axis direction through the transverse pin 25. When the length of the cotton strip passing directly below the cutter 62 is the preset length, the first motor 22 stops rotating, and the cutter 62 cuts the cotton strip, and the cut cotton strip is taken away. The first motor 22 continues to rotate forward until the cotton strip on the transverse pin 25 is cut to the point that the remaining material is not usable.

[0060] The first motor 22 reverses, and the transverse pin 25 brings the tail material back to the end of the feeding track 21 until the transverse pin 25 is blocked by the baffle 26. The fourth cylinder 24 drives the transverse pin 25 to be pulled out of the tail material. The first motor 22 rotates forward and drives the transverse pin 25 to move to the front end of the tail material. The transverse pin 25 extends and is located at the front end of the tail material. The first motor 22 reverses and drives the transverse pin 25 to push the tail material away from the end of the feeding track 21.

[0061] This utility model is reasonably and ingeniously designed, which can automatically and quickly separate the cotton strip from the block cotton 5 in the material picking area and place it on the feeding track 21. The feeding device 2 automatically conveys the cotton strip and the cutter 62 cuts it to the required length, realizing the automation of cotton application and improving production efficiency.

[0062] The above description is merely a preferred embodiment of this application and does not constitute any limitation on this application. Any person skilled in the art can make many possible variations and modifications to the technical solution of this application, or modify it into equivalent embodiments, without departing from the scope of the technical solution of this application.
