Detailed Implementation

[0031] The technical solutions of this application will be further described below with reference to specific embodiments, but this application is not limited to these embodiments.

[0032] like Figures 1 to 6 As shown, this embodiment proposes a paper bag feeding mechanism, including: a first driving component 11, an adjusting component 12, a feeding component 13, and a lifting component 14.

[0033] The first drive assembly 11 includes a fixed arm 15, a first slide rail assembly 16, a movable seat 17 and a first telescopic member 18. The movable seat 17 is mounted on the fixed arm 15 via the first slide rail assembly 16, and the output end of the first telescopic member 18 is connected to the movable seat 17.

[0034] The adjustment assembly 12 is mounted on the fixed arm 15 via a fixed plate or fixed base, and the adjustment assembly 12 has an output end that can move in a straight line. The output end of the adjustment assembly 12 is used to adjust the position of the first telescopic member 18.

[0035] The material picking assembly 13 is mounted on the movable seat 17 via the lifting assembly 14, and the material picking assembly 13 has a suction cup assembly 19 for adsorbing the paper bag.

[0036] In this solution, the first telescopic component 18 can drive the material picking component 13 to move back and forth in the horizontal direction between the two workstations. When the stroke of the first telescopic component 18 is insufficient, the operation of the material picking component 13 cannot be guaranteed. Therefore, this solution adds an adjustment component 12 to control the position of the first telescopic component 18, thereby increasing the travel distance of the paper bag during delivery, thus ensuring the effective operation of the material picking component 13, and has the advantages of simple structure and convenient adjustment.

[0037] The suction cup assembly 19 is a prior art technology. The suction cup assembly 19 has one or more suction cup portions 38 at its end along its length direction. The suction cup portions 38 achieve adsorption of the paper bag by squeezing out the internal air.

[0038] The fixed arm 15 in this solution can be installed on the cabinet via a mounting bracket. Alternatively, the fixed arm 15 can be installed on a support platform via a lifting structure. Other existing methods for installing the fixed arm 15 can also be used.

[0039] In addition, this solution can not only adsorb paper bags, but also lightweight plastic sheets, plastic plates or plastic bags.

[0040] In addition, the suction cup assembly 19 in this solution can be a physical compression suction cup as in the prior art, or it can be a suction cup pressure controlled by an air pump and a solenoid valve as in the prior art to achieve stable adsorption and material picking.

[0041] As one embodiment of this example, the first slide rail assembly 16 includes a first guide rail 20, a first slider 21 and a second slider 22. The first guide rail 20 is fixed on the fixed arm 15, and the first slider 21 and the second slider 22 are mounted on the first guide rail 20.

[0042] The first slider 21 is used to fix the movable seat 17;

[0043] The second slider 22 is fixed with a mounting base 23, and the mounting base is fixed with a first telescopic component 18.

[0044] In this design, the first slide rail assembly 16 is used to ensure the smooth movement of the movable seat 17, preventing the paper bag from falling off due to shaking during transportation. The first telescopic component 18 is a pneumatic or electric cylinder. Pneumatic or electric cylinders are existing technologies, and their working principles will not be described in detail.

[0045] In one embodiment of this invention, the adjusting component 12 is a second telescopic member 24. The second telescopic member 24 is a pneumatic cylinder or an electric cylinder.

[0046] The length directions of the first telescopic member 18 and the second telescopic member 24 are parallel, and are also parallel to the length direction of the first guide rail 20.

[0047] In this design, there are two first sliders 21. These are used to ensure that the movable base 17 is subjected to even force during installation. There is one second slider 22 in this design.

[0048] As one embodiment of this invention, the lifting assembly 14 includes a third telescopic member 25, a guide block 26, and a guide rod 27.

[0049] A third telescopic component 25 and a third guide block 26 are fixed on the movable base 17. The output end of the third telescopic component 25 is arranged vertically and is fixed on the material handling assembly 13.

[0050] The guide rod 27 is slidably inserted into the guide hole of the guide block 26 in the vertical direction, and the lower end of the guide rod 27 is fixed on the material picking assembly 13.

[0051] In this design, the third telescopic component 25 is a pneumatic or electric cylinder, and its extension direction is vertical. The guide rod 27 is provided to make the vertical movement of the drive assembly smoother.

[0052] As one embodiment of this example, the material handling assembly 13 includes a support arm 28 and a second drive assembly 29. The output ends of the guide rod 27 and the third telescopic member 25 are respectively fixedly connected to the support arm 28 through a fixing block or a connecting block. The second drive assembly 29 is mounted on the support arm 28 and is used to drive the suction cup assembly 19 to rotate.

[0053] The second drive component 29 is used to control the suction cup component 19 to rotate at a certain angle. The specific rotation angle can be adjusted according to the actual scenario. Generally, the rotation angle is 90°, which is used to adjust the paper bag in a flat state to a vertical state.

[0054] For ease of understanding, this solution provides a simplified description of the extended subsequent processes. During loading, an additional suction cup is added, controlled by a horizontal drive. The suction cup and suction cup assembly 19 are located on opposite sides of the paper bag. When the horizontal drive pulls back the additional suction cup, the paper bag opening opens, and the external inlet pipe delivers the masterbatch product into the paper bag. This is merely to illustrate one application scenario and is not intended to limit the application scenarios of the paper bag feeding mechanism in this solution.

[0055] In one embodiment of this invention, the second drive component 29 is a motor or rotary cylinder as described in the prior art, the specific structure of which is not shown in the accompanying drawings. Directly using a motor or rotary cylinder can achieve angle adjustment of the suction cup assembly 19, in which case the output shaft of the second drive component 29 is fixedly connected to the suction cup assembly 19.

[0056] As one implementation method of this embodiment, unlike the above, this embodiment proposes another structural form of the second driving component 29, as follows:

[0057] The second drive assembly 29 includes a fourth telescopic member 30, a second slide rail assembly 31, a mounting plate 32, a connecting arm 33, and a limiting member 34. The mounting plate 32 is mounted on the support arm 28 via the second slide rail assembly 31. A rotating shaft 35 is slidably mounted on the support arm 28. One end of the rotating shaft 35 is fixed to a suction cup assembly 19 via a support 36, and the other end of the rotating shaft 35 is fixed to the connecting arm 33. The limiting member 34 is rotatably mounted on the connecting arm 33.

[0058] The support arm 28 is provided with a guide channel 37, in which a limiting member 34 is slidably installed. The guide channel 37 is used to make the limiting member 34 move along a curve.

[0059] In this design, the guide channel 37 is used to change the height of the limiting member 34. Since the height of the rotating shaft 35 remains constant, the connecting arm 33 will swing at a certain angle when the height of the limiting member 34 changes. Because the length direction of the connecting arm 33 is parallel to the length direction of the suction cup assembly 19, the suction cup assembly 19 will inevitably rotate when the connecting arm 33 rotates.

[0060] Furthermore, the guide channel 37 is used to rotate the connecting arm 33 by 90°.

[0061] As one embodiment of this invention, the limiting member 34 is one of a rolling column, a roller, or a bearing.

[0062] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
