[0045] The specific embodiments of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0046] As attached Figure 1-12 As shown, a tube material feeding device provided by the present invention comprises two sets of tube storage racks 1 arranged opposite to each other, and the tube storage racks 1 comprise a tube clamping mechanism 2 and a lifting and adjusting slide 3 for driving the tube clamping mechanism 2 to lift and lower;

[0047] The material tube clamping mechanism 2 includes two groups of material tube width limit plates 20 and an opening and closing adjustment component 21 for adjusting the spacing between the two groups of material tube width limit plates 20. The opening and closing adjustment component 21 includes a width adjustment screw rod 22, an adjustment guide slide rod 23 and an adjustment linkage rod 24. The width adjustment screw rod 22 and the adjustment guide slide rod 23 are perpendicular to each other. The two groups of material tube width limit plates 20 are slidably connected to the adjustment guide slide rod 23 through two groups of guide slide blocks 25, and the two groups of guide slide blocks 25 are respectively located on both sides of the width adjustment screw rod 22. A first screw rod nut 26 is threadedly connected to the width adjustment screw rod 22. Both ends of the adjustment linkage rod 24 are respectively hinged to the first screw rod nut 26 and the guide slide block 25. The two ends of the packaging material tube 90 are respectively accommodated in the gap between the two groups of material tube width limit plates 20 of the two groups of tube storage racks 1.

[0048] Specifically, when it is necessary to adjust the tube storage rack 1 according to the size of the packaging material tube 90, the width adjustment screw 22 can be rotated to drive the first screw nut 26 to slide along the width adjustment screw 22, and the first screw nut pushes the adjustment linkage rod 24 to rotate, drives the guide slider 25 to slide along the adjustment guide slider 23, and drives the two groups of material tube width limit plates 20 to slide toward or in the opposite direction, and adjust the spacing between the two groups of material tube width limit plates 20, so as to adapt to packaging material tubes 90 of different widths. Compared with the existing technology, it has better adaptability, can effectively improve the speed of replacing packaging material tubes 90 of different sizes, and simplify the replacement process.

[0049] Further, the opening and closing adjustment assembly 21 also includes a transmission link 27, and the adjustment linkage rod 24 is provided with at least two groups, one end of the two groups of adjustment linkage rods 24 is respectively connected to the two ends of the transmission link 27, and the other end of the two groups of adjustment linkage rods 24 is connected to the guide slider 25. The two groups of adjustment linkage rods 24, the transmission link 27 and the guide slider 25 form a parallelogram linkage mechanism, and one end of the transmission link 27 is connected to the first screw nut 26;

[0050] Two groups of adjusting guide slide bars 23 are provided, and the two ends of the guide slide block 25 are respectively slidably connected to the two groups of adjusting guide slide bars 23 through linear bearings. A width adjusting handle 28 is provided at one end of the width adjusting screw rod 22. Since the width limit plate 20 of the material tube is relatively long, the adjusting linkage rod 24 and the adjusting guide slide bar 23 are added to ensure that the width limit plate 20 of the material tube can slide and adjust smoothly, and the width adjusting screw rod 22 is rotated by rotating the width adjusting handle 28;

[0051] A first locking handle bolt 29 is provided on the first screw nut 26, and the front end of the first locking handle bolt 29 is opposite to the width adjustment screw. After the spacing between the two groups of material pipe width limit plates 20 is adjusted, the first locking handle bolt 29 is rotated to make the front end of the first locking handle bolt 29 press against the width adjustment screw 22, lock the first screw nut 26, and lock the spacing between the two groups of material pipe width limit plates 20. When it is necessary to adjust the spacing between the two groups of material pipe width limit plates 20, loosen the first locking handle bolt 29.

[0052] Further, the lifting adjustment slide 3 includes a lifting frame 30 and a lifting slide 33. The lifting slide 33 is slidably connected to the lifting frame 30 through a lifting slider and a lifting guide rail. The material tube clamping mechanism 2 is arranged on the lifting slide 33. A lifting adjustment screw 34 is arranged on the lifting slide 33. The lifting adjustment screw 34 is parallel to the lifting guide rail. Both ends of the lifting adjustment screw are rotatably connected to the lifting slide 33. A second screw nut 35 is threadedly connected to the lifting adjustment screw 34. The second screw nut 35 is connected to the lifting frame 30 through a lifting connecting plate 31. A lifting adjustment handle 36 is arranged at one end of the lifting adjustment screw 34.

[0053] A second locking handle bolt 37 is provided on the lifting stand 30, and a lifting adjustment panel 38 is provided on the lifting slide 33. A lifting adjustment guide hole 39 is provided on the lifting adjustment panel 38 along the lifting direction of the lifting slide 33. The second locking handle bolt 37 passes through the lifting adjustment guide hole 39 and the lifting connecting plate 31 and is connected to the second screw nut. When it is necessary to adjust the horizontal height of the material tube clamping mechanism 2 to adapt to the height of the material tubes 90 of different sizes, the lifting adjustment screw 34 can be raised and lowered relative to the second screw nut by rotating the lifting adjustment screw, thereby driving the lifting slide 33 to be raised and lowered, and adjusting the horizontal height of the material tube clamping mechanism 2 to adapt to the height of the material tubes 90 of different sizes;

[0054] A lifting adjustment scale is provided on the lifting adjustment panel 38 along the lifting direction of the lifting slide 33, and a lifting adjustment scale pointer 32 cooperating with the lifting adjustment scale is provided on the lifting connecting plate 31. By referring to the lifting adjustment scale pointer 32 and the lifting adjustment scale, the horizontal height of the material tube clamping mechanism 2 can be known, and at the same time, it is ensured that the two groups of material tube clamping mechanisms 2 are maintained at the same horizontal height.

[0055] Furthermore, the tube material feeding device also includes a feeding slide and a feeding platform. The tube storage rack 1 is arranged above the feeding slide, and the feeding platform is arranged at the front end of the feeding slide. The tube storage rack 1 is provided with a supporting mechanism for supporting the packaging material tube 90. The supporting mechanism includes a front lifting support platform 61 and a rear lifting support platform 64. The front lifting support platform 61 and the rear lifting support platform 64 are arranged along the sliding direction of the feeding slide. The front lifting support platform 61 includes a front support plate 62 and a front tube cylinder 63 for driving the front support plate 62 to rise and fall. The rear lifting support platform 64 includes a rear support plate 65 and a rear tube cylinder 66 for driving the rear support plate 65 to rise and fall.

[0056] The feeding slide comprises a front push tube sliding frame 40, a rear push tube sliding frame 50, a push tube guide rail 55 and a slide frame driving mechanism 56. The front push tube sliding frame 40 and the rear push tube sliding frame 50 are slidably connected to the push tube guide rail 55 through a slider. The front push tube sliding frame 40 and the rear push tube sliding frame 50 are connected to each other through an adjusting connecting rod 57. One end of the adjusting connecting rod 57 can be fixedly connected to the front push tube sliding frame 40 or the rear push tube sliding frame 50, and slidably connected to the other end. After adjusting the spacing between the front push tube sliding frame 40 and the rear push tube sliding frame 50, the adjusting connecting rod 57 can be adjusted to the front push tube sliding frame 40 or the rear push tube sliding frame 50. The fastener can be locked with the adjustment link 57 to adapt to packaging material tubes 90 of different lengths. The slide frame driving mechanism 56 is connected to the front push tube slide frame 40 or the rear push tube slide frame 50. The slide frame driving mechanism 56 can be a cylinder, a linear motor, or a motor-driven synchronous belt to drive the front push tube slide frame 40 and the rear push tube slide frame 50 to slide along the push tube guide rail 55. In this embodiment, a motor plus synchronous belt driving method is adopted, and one of the front push tube slide frame 40 and the rear push tube slide frame 50 is fixed to the synchronous belt;

[0057] The projections of the front support plate 62 and the rear support plate 65 in the vertical direction do not overlap with the projections of the tube pusher guide rail 55 and the slide frame driving mechanism 56 in the vertical direction, that is, the lifting and lowering of the front support plate 62 and the rear support plate 65 will not interfere with the tube pusher guide rail 55 and the slide frame driving mechanism 56;

[0058] The pushing and changing of the packaging material tube 90 is achieved through the cooperation of the supporting mechanism and the feeding slide. Specifically, in the initial state, the front pushing tube sliding frame 40 and the rear pushing tube sliding frame 50 are located below the tube placing storage rack 1, and the packaging material tube 90 located at the lower end of the tube placing storage rack 1 is supported on the front support plate 62 and the rear support plate 65 at the same time. The front support plate 62 and the rear support plate 65 synchronously drop to the height of a packaging material tube 90. At this time, the two ends of the packaging material tube 90 are respectively located on the front pushing tube sliding frame 40 and the rear pushing tube sliding frame 50. The front pushing tube sliding frame 40 and the rear pushing tube sliding frame 50 are driven by the sliding frame driving mechanism 56 to synchronously move the packaging material tube 90 toward the feeding table. After the rear pushing tube sliding frame 50 passes over the rear support plate 65 and the front support plate 62, the rear support plate is raised in sequence. 65 and the front support plate 62 support the second packaging material tube 90. After the first packaging material tube 90 completes feeding, the front push tube slide frame 40 and the rear push tube slide frame 50 are driven by the sliding frame driving mechanism 56 to synchronously move the packaging material tube 90 to the tube storage rack 1. At this time, since the front support plate 62 and the rear support plate 65 are located above the packaging material tube 90, the packaging material tube 90 loses its support and falls downward from the feeding slide, completing the throwing of the empty packaging material tube 90. Then the front support plate 62 and the rear support plate 65 synchronously drop to the height of a packaging material tube 90 to carry out the next cycle of feeding, thereby completing the tube replacement of the packaging material tube 90. Compared with the existing feeding device, the tube replacement efficiency is higher. At the same time, due to the use of the lower throwing tube, it is not easy to cause the tube throwing failure, thereby improving the reliability of the device.

[0059] Furthermore, the front push tube sliding frame 40 includes a front sliding base 41 and a lifting stop arm 42. The front sliding base 41 is slidably connected to the push tube guide rail 55 by a slider. The lifting stop arm 42 includes a front push material baffle 43 and a stop arm cylinder 44 for driving the front push material baffle 43 to rise and fall. The front push material baffle 43 is provided with two groups of front stop blocks 45 on the side facing the rear push material tube sliding frame. A gap is formed between the two groups of front stop blocks 45 for accommodating the front end of the packaging material tube 90. Since the front port of the packaging material tube 90 cannot be closed when the packaging material tube 90 is feeding, and if the front port is not closed when the packaging material tube 90 is pushed, there is a risk of components falling. For this reason, the front push material baffle 43 is driven to rise and fall by the stop arm cylinder 44 to achieve the closing and opening of the front port of the packaging material tube 90. The front port of the packaging material tube 90 is opened when feeding, and the front port of the packaging material tube 90 is closed when pushing the material tube.

[0060] The rear push tube sliding frame 50 includes a rear sliding base 51 and an L-shaped stop arm 52. The rear sliding base 51 is slidably connected to the push tube guide rail 55 through a slider. The L-shaped stop arm 52 is provided with a push tube stop block 53. The L-shaped stop arm 52 is provided with two groups of rear stop edge blocks 54 on the side facing the front push tube sliding frame 40. The two groups of rear stop edge blocks 54 are respectively located on both sides of the push tube stop block 53, and a gap is formed between the two groups of rear stop edge blocks 54 for accommodating the rear end of the packaging material tube 90.

[0061] Furthermore, the tube material feeding device also includes a frame 80, and the tube storage rack 1, the feeding slide and the feeding platform are all arranged on the frame 80. The frame 80 is provided with two sets of side fixing plates 81 for supporting the tube storage rack 1. The tube storage rack 1 away from the feeding platform is slidably connected to the two sets of side fixing plates 81 through guide rails and sliders. When it is necessary to adjust the distance between the two sets of tube storage racks 1 according to the length of the packaging material tube 90, the tube storage rack 1 away from the feeding platform can be pushed to slide along the guide rails. Dynamic adjustment, after the adjustment is completed, it can be locked with the guide rail. An adjustment scale 82 is provided on the side fixing plate 81 along the sliding direction of the tube storage rack 1. When adjusting the tube storage rack 1, the distance between the two groups of tube storage racks 1 can be determined by adjusting the scale 82. An empty tube material trough 83 for guiding the throwing of empty packaging material tubes 90 is provided under the tube storage rack 1. The empty tube material trough 83 is tilted downward, and the empty packaging material tube 90 falls into the empty packaging material tube 90 and then slides downward to the storage area.

[0062] Furthermore, the feeding table includes a vibration table 71 and a track pad 72 for supporting the material tube, the track pad 72 is arranged on the vibration table 71, the track pad 72 and the tube pushing guide rail 55 are parallel to each other, and the vibration table 71 is provided with a lifting and clamping mechanism for cooperating with the track pad 72 to clamp the material tube, the lifting and clamping mechanism includes a pressing plate 73 and a lifting cylinder for driving the pressing plate 73 to lift, the pressing plate 73 is located above the track pad 72, and the front tube pushing slide frame 40 and the rear tube pushing slide frame 50 push the packaging material tube 90 onto the track pad 72, and the front of the packaging material tube 90 When the end rests against the discharge port of the feeding table, the packaging material tube 90 is fixed on the track pad 72 by the pressure plate 73, the front push baffle 43 rises, and the vibration table 71 vibrates to start feeding. It should be noted that by setting the in-place sensor and the shading sheet, it is possible to synchronously detect whether the feeding slide has pushed the packaging material tube 90 into place, and synchronously trigger and control the lifting and lowering of the front push baffle 43. The in-place sensor can be set on the feeding table, and the shading sheet can be set on the front push tube sliding frame 40. After the front push tube sliding frame 40 is in place, the in-place sensor is triggered by the shading sheet.
