Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment, specifically to a paper bag flaring mechanism. Background Technology

[0002] The masterbatch generates a lot of dust during packaging, so existing technologies usually use mechanical tools to open the packaging bag so that the masterbatch can be smoothly loaded into the packaging bag.

[0003] In existing technologies, suction cups are typically used to adhere to the outside of the packaging bag. The suction cups on both sides are relatively far apart, thus opening the packaging bag. At this time, the bag opening is not effectively supported, so the bag opening will float, making it difficult to fill the bag. Furthermore, during the masterbatch packaging process, the packaging bag will vibrate or float, which can easily cause the suction cups to detach from the packaging bag, further causing the bag opening to bend or retract, thus affecting the packaging efficiency of the masterbatch.

[0004] Therefore, the technical problem that this application needs to solve is: how to fully open the bag opening of the masterbatch. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model proposes a paper bag widening mechanism. In this solution, when the first driving member drives the driving plate towards the moving blocks, the driving plate passes between the two moving blocks. Under the action of the two first inclined surfaces, the distance between the two moving blocks increases, thereby fully opening the paper bag opening and effectively preventing the bag opening from floating. This ensures that the bag opening does not float after widening, improving its stability and facilitating the packaging of masterbatch.

[0006] Specifically, this utility model proposes a paper bag flaring mechanism, wherein there are two paper bag flaring mechanisms, respectively arranged on both sides of the paper bag; wherein the paper bag flaring mechanism includes:

[0010] Preferably, each of the two movable blocks has a second inclined surface on the side facing the drive plate, and the second inclined surface is used to allow the drive plate to pass between the two movable blocks.

[0011] Preferably, the drive plate is mounted on the support plate via a first slide rail assembly.

Detailed Implementation

[0026] 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.

[0027] like Figures 1 to 5 As shown, this embodiment proposes a paper bag flaring mechanism, wherein there are two paper bag flaring mechanisms 11, which are respectively arranged on both sides of the paper bag 12; wherein, the paper bag flaring mechanism 11 includes:

[0028] The support plate 13 has a horizontal first mounting surface 14, a support platform 15 is fixed on the first mounting surface 14, and the top of the support platform 15 has a second mounting surface 16.

[0029] Two movable blocks 17 are mounted on the second mounting surface 16 via elastic reset members. Each movable block 17 has an expansion arm 36 fixed on it.

[0030] The first driving member 18 has an output end that moves in a straight line, and a driving plate 19 is fixed on the output end of the first driving member 18. The driving plate 19 has two first inclined surfaces 20, which are used to control the distance between the two moving blocks 17.

[0031] The technical advantage of this solution is that it proposes a method for widening the opening of the paper bag 12. First, the expansion arm 36 in each paper bag 12 expansion mechanism is inserted into the opening of the paper bag 12. Then, when the first driving member 18 drives the driving plate 19 towards the moving block 17, the driving plate 19 passes between the two moving blocks 17. Under the action of the two first inclined surfaces 20, the distance between the two moving blocks 17 increases, thereby widening the opening of the paper bag 12 and effectively preventing the opening of the paper bag 12 from floating. This ensures that the opening does not float after widening, improving the stability of the opening and making it easier to package the masterbatch.

[0032] Furthermore, the expansion arm 36 is L-shaped, with a horizontal arm at the top and a vertical arm fixed to the lower end of the horizontal arm.

[0033] In one embodiment of this invention, each of the two movable blocks 17 has a second inclined portion 21 on the side facing the drive plate 19. The second inclined portion 21 is used to allow the drive plate 19 to pass between the two movable blocks 17. In this solution, the two second inclined portions 21 form a notch, which facilitates the drive plate 19 to pass between the two movable blocks 17.

[0034] In one embodiment of this invention, the drive plate 19 is mounted on the support plate 13 via the first slide rail assembly 37.

[0035] The first slide rail assembly 37 is existing technology, specifically including a guide rail and a slider. Its structure and working principle will not be described in further detail.

[0036] As one implementation of this embodiment, the first driving member 18 is the first telescopic member 22, which is mounted on the first mounting surface 14 via the support base 23.

[0037] The first telescopic component 22 in this solution uses a pneumatic cylinder or an electric cylinder. Pneumatic cylinders and electric cylinders are existing technologies, and their working principles will not be described in detail.

[0038] The length of the first telescopic member 22 is arranged along the X-axis, and the movement direction of the moving block 17 is arranged along the Y-axis.

[0039] Furthermore, the elastic reset element includes a positioning block 38, a moving rod 39, and a spring 40.

[0040] The positioning blocks 38 are configured in two sets, and the two sets of positioning blocks 38 are respectively fixed at both ends of the second mounting surface 16. The moving block 17 is located between the two sets of positioning blocks 38. A moving rod 39 is slidably passed through each set of positioning blocks 38. The end of the moving rod 39 is fixed to the moving block 17. A spring 40 is sleeved on the moving rod 39, and the spring 40 is located between the moving block 17 and the positioning block 38.

[0041] Each set of positioning blocks 38 contains multiple positioning blocks 38, which are used to enable the moving rod 39 to move smoothly.

[0042] As one embodiment of this invention, a lifting assembly 24 is also included. The lifting assembly 24 has an output end that moves in a vertical direction, and a support plate 13 is mounted on the output end of the lifting assembly 24.

[0043] The lifting assembly 24 includes a mounting base 41, a lifting cylinder 42, a sliding rod 43, and a sleeve 44. The sleeve 44 and the lifting cylinder 42 are fixed on the mounting base 41. The top of the sliding rod 43 is fixed on the support plate 13. The lower end of the sliding rod 43 can slide vertically through the inner hole of the sleeve 44. The lifting cylinder 42 is used to control the height of the support plate 13.

[0044] In one embodiment of this invention, a base plate 25 is also included. The lifting assembly 24 is mounted on the base plate 25 via a second slide rail assembly 26, wherein the guide rail of the second slide rail assembly 26 is fixed to the base plate 25 by a shim block. A second driving member 27 is mounted on the base plate 25 via a fixing seat, and the second driving member 27 is used to drive the lifting assembly 24 to move in a straight line.

[0045] The mounting base 41 is fixed to the fixing plate 48, which in turn is fixed to the slider of the second slide rail assembly 26. The second driving component 27 is the second telescopic component 45, which can be a pneumatic or electric cylinder as used in the prior art, and its telescopic direction is arranged along the X-axis. The second telescopic component 45 is threaded or welded onto the fixing plate 48.

[0046] As one embodiment of this example, a support frame 28 is fixedly installed on the base plate 25. A third driving member 29, a guide component 30, and a suction cup assembly 31 are fixed on the support frame 28. The suction cup assembly 31 is installed on the support frame 28 through the guide component 30. The third driving member 29 is used to drive the suction cup assembly 31 to move.

[0047] As one embodiment of this example, the support frame 28 includes a vertical frame 32 and a mounting plate 33, with the mounting plate 33 fixed to the upper end of the vertical frame 32.

[0048] The guide assembly 30 includes a movable arm 34 and a guide rod 35. The movable arm 34 is movably inserted into the guide hole of the mounting plate 33 via the guide rod 35. The movable arm 34 is used to fix the suction cup assembly 31.

[0049] The third driving component 29 is the third telescopic component 46, which can be a pneumatic cylinder or an electric cylinder as used in the prior art, and its telescopic direction is arranged along the X-axis. The output shaft of the third telescopic component 46 is threadedly fixed to the moving arm 34.

[0050] Furthermore, the suction cup assembly 31 is prior art, wherein the suction cup assembly 31 has a suction cup portion 47 for adsorbing the paper bag 12.

[0051] The suction cup part 47 can adopt the physical compression adsorption method in the prior art, that is, to adsorb the paper bag 12 by expelling the internal air of the suction cup part 47 to achieve negative pressure.

[0052] In addition, the suction cup part 47 can also be connected to a suction pump through a conduit, wherein a negative pressure valve is installed on the conduit to regulate the internal pressure of the suction cup part 47 and maintain the air pressure stability of the suction cup part 47. The working method of the suction cup part 47 described in this paragraph is the prior art, and its further structure and working principle will not be described in detail.

[0053] The principle behind the flaring of the paper bag 12 in this solution is as follows:

[0054] Step 1: Feed the paper bag 12 between the two paper bag flaring mechanisms 11 by means of a robotic arm or manually.

[0055] Step 2: The third telescopic component 46 moves toward the paper bag 12. At this time, the suction cup part 47 of the suction cup assembly 31 suctions the surface of the paper bag 12. Then, the third telescopic components 46 on both sides of the paper bag 12 return to a certain distance. At this time, the bag opening of the paper bag 12 is open, but the bag opening at the top of the paper bag 12 is in a floating state. At this time, the masterbatch cannot be packaged.

[0056] Step 3: The second telescopic component 45 drives the lifting component 24 and the support plate 13 to move toward the paper bag 12. When the expansion arm 36 is directly above the bag opening, the lifting component 24 then drives the support plate 13 to descend. At this time, the lower end of the expansion arm 36 enters the bag opening of the paper bag 12.

[0057] Step 4: The first telescopic component 22 drives the drive plate 19 to move toward the paper bag 12 and squeezes the moving block 17, so that the expansion arm 36 initially widens the opening of the paper bag 12.

[0058] Step 5: The second telescopic component 45 retracts a certain distance. At this time, the expansion arms 36 in the two paper bag flaring mechanisms 11 move in opposite directions. The opening of the paper bag 12 is fully opened and will not float, so as to facilitate the packaging of the masterbatch.

[0059] 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.
