Description

Technical Field

[0001] This invention relates to the field of feeding frame technology, and in particular to a multi-angle automatic feeding frame. Background Technology

[0002] The foam material (i.e. raw material) of non-woven fabric is mainly polypropylene (PP material), which is made through high-temperature melting, spinning and other processes. Some products may use plastic materials such as polyethylene, or natural plant fibers (such as corn fiber) as raw materials.

[0003] During the raw material feeding process, the top layer is fed to the bottom layer. Since there is no reliable way to fix the bags, operators need to frequently check and manually adjust the position of the bags during the conveying and feeding process to prevent the bags from slipping or shifting. This not only increases labor costs, but also causes the feeding process to be discontinuous, affecting production efficiency. Summary of the Invention

[0004] This invention discloses a multi-angle automatic feeding frame, which aims to solve the technical problem that when there is no reliable bag fixing method, frequent manual inspection and adjustment of bag position to prevent slippage and displacement are required during the conveying and feeding process, which increases labor costs, causes the feeding process to be interrupted, and reduces production efficiency.

Detailed Implementation

[0049] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0050] The multi-angle automatic feeding frame disclosed in this invention is mainly used in scenarios where there is no reliable bag fixing method, and frequent manual inspection and adjustment of bag position to prevent slippage and displacement are required during the conveying and feeding process, which increases labor costs, causes the feeding process to be interrupted, and reduces production efficiency.

[0051] Reference Figures 1-8 A multi-angle automatic feeding frame, comprising:

[0052] Feeding auxiliary frame 1, with an annular pipe 6 installed inside the feeding auxiliary frame 1;

[0053] Automatic conveyor 2 is set on one side of the feeding auxiliary frame 1. A conveyor belt 3 is set on the inner side of the automatic conveyor 2. The conveyor belt 3 is used to transport bags filled with foam material.

[0054] Multiple positioning control devices 4 are located above the conveyor belt 3, and the bottom inner side of each positioning control device 4 is fixedly connected to the outer side of the automatic conveyor table 2.

[0055] The feeding rack 5 is located between the annular pipe 6 and the automatic conveyor table 2;

[0056] Cutting blade 9 is positioned above the annular pipe 6 and is used to cut the head end of the bag containing foam material.

[0057] The clip-on bag adjustment assembly 11 is located inside the side of the feeding auxiliary frame 1 near the automatic conveyor table 2. The clip-on bag adjustment assembly 11 is used to clip the head end of the bag filled with foam and adjust the angle to facilitate unloading.

[0058] The foam bag roll-up and push-out assembly 18 is located above the feeding rack 5. The foam bag roll-up and push-out assembly 18 is used to roll up the tail end of the bag filled with foam material and push out the foam material in the bag during feeding.

[0059] Reference Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 In a preferred embodiment, the clip-on bag adjusting assembly 11 includes:

[0060] Both fixed frames 1101 are fixedly connected to the inside of the side of the feeding auxiliary frame 1 near the automatic conveyor table 2;

[0061] Two symmetrical movable plates 1105 are located between two fixed frames 1101;

[0062] Multiple clips 1113 are fixedly connected to the bottom end of the movable plate 1105, which is away from the feeding rack 5;

[0063] Multiple extrusion plates 1114 are located between the clips 1113;

[0064] Two bottom buckle plates 1115 are fixedly connected to the top of the movable plate 1105 near the feeding rack 5. Two holes and slots are opened on the bottom buckle plates 1115, and the clamping nails 1113 can be moved into the inside of the holes and slots.

[0065] In this invention, the clip-on bag adjusting assembly 11 further includes:

[0066] The guide rod 1104 is fixedly connected to the inside of one of the connecting frames, and the motor frame 1107 is fixedly connected to the inside of the other connecting frame;

[0067] The bidirectional motor 1103 is fixedly connected to the inner side of the motor frame 1107. The power output shafts at both ends of the bidirectional motor 1103 are connected to threaded rods 1102 through couplings. The opposite ends of the threaded rods 1102 are movably connected to the inner sides of the connecting frame near the motor frame 1107.

[0068] Two symmetrical sliding plates 1108 are slidably connected to the outside of two threaded rods 1102 and guide rods 1104;

[0069] Two symmetrical drive motors 1110 are each located on one side of the two sliding plates 1108.

[0070] In this invention, the power output shafts of the two symmetrical drive motors 1110 are connected to gear plates 1111 via couplings. The opposite sides of the gear plates 1111 are rotatably connected to the opposite sides of the two symmetrical sliding plates 1108. The outer sides of the gear plates 1111 are rotatably connected to arc-shaped gear rotating plates 1109. The arc-shaped gear rotating plates 1109 and the gear plates 1111 are meshed through tooth grooves. One side of the arc-shaped gear rotating plates 1109 is fixedly connected to the opposite sides of the two symmetrical moving plates 1105. A connecting plate 1106 is fixedly connected between the two symmetrical moving plates 1105. A compression spring 1112 is fixedly connected to the bottom end of the moving plate 1105 near the clamping pin 1113. The bottom end of the compression spring 1112 is fixedly connected to the top end of the pressing plate 1114.

[0071] Specifically, when the bidirectional motor 1103 starts, the power output shafts at both ends drive the threaded rod 1102 to rotate via couplings. Since the sliding plates 1108 are in sliding engagement with the threaded rod 1102 and guide rod 1104 respectively (two sliding plates 1108 are guided linearly along the guide rod 1104, while the other two are driven threadedly along the threaded rod 1102), as the threaded rod 1102 rotates, the two sliding plates 1108, along with their respective connected moving plates 1105, move closer to each other. During this process, the guide rod 1104 ensures the linear stability of the moving plate 1105 on one side. The bidirectional motor 1103 synchronously drives the moving plates 1105 on both sides to move symmetrically and at a uniform speed until... The snap fastener 1113 approaches and pierces the slot in the bottom buckle plate 1115, initially creating a piercing limit on the bag, preparing for subsequent snap fastening. As the moving plate 1105 continues to move closer, the snap fastener 1113 is fully inserted into the slot in the bottom buckle plate 1115. At this point, the bag's head end, pierced by the snap fastener 1113, is positioned between the snap fastener 1113 and the bottom buckle plate 1115. Simultaneously, as the moving plate 1105 approaches, the compression plate 1114 moves downward with the upper moving plate 1105, gradually contacting and compressing the bottom buckle plate 1115. The compression spring 1112 undergoes elastic deformation under the pressure of the compression plate 1114, providing the compression plate 1114 with a reverse elastic force, which, in conjunction with the snap fastener 111... The piercing of plate 3 and the connection of the bottom buckle plate 1115 fix the two ends of the bag from the top and bottom. After the buckle pin 1113 pierces the bag, it is embedded in the groove to achieve mechanical limiting. The compression plate 1114 and the bottom buckle plate 1115 are elastically compressed by the compression spring 1112, and clamping force is applied from both sides of the bag end to stably clamp the two sides of the bag end between the two moving plates 1105. When it is necessary to adjust the bag feeding angle, the drive motor 1110 starts, and the power output shaft drives the gear plate 1111 to rotate through the coupling. Since the arc gear rotating plate 1109 and the gear plate 1111 are meshed through the tooth groove (the gear plate 1111 is the driving wheel and the arc gear rotating plate is the driving wheel), the gear plate 1109 is the driving wheel and the gear plate 1111 is the driving wheel. 1109 is a driven arc-shaped tooth structure. When the gear plate 1111 rotates, the arc-shaped gear rotating plate 1109 rotates in an arc shape, which in turn drives the movable plate 1105 fixedly connected to it to swing around the meshing point at a certain angle. The two movable plates 1105 are connected by a connecting plate 1106, which can ensure synchronous linkage or coordinated swing according to a set trajectory when adjusting the angle. This allows the entire head of the bag clamped to adjust its tilt angle as the angle of the movable plate 1105 changes, adapting to different material feeding direction requirements, and allowing the foam to fall more smoothly from the head of the bag through the gap in the clamping area (the foam falling space reserved between components such as the clamping nail 1113 and the extrusion plate 1114).

[0072] In actual operation, the clip 1113 pierces the hole slot of the bottom buckle plate 1115, and combined with the elastic compression of the extrusion plate 1114 and the compression spring 1112, it achieves a stable clamping of the bag head from both the piercing limit and double-sided clamping aspects. This can effectively prevent the bag from slipping or shifting, ensure the stability of the bag position during the conveying and unloading process after the foam filling, and improve the reliability of the feeding process.

[0073] It should be noted that the bidirectional motor 1103 drives the moving plate 1105 to close and achieve clamping, and the drive motor 1110 completes the angle adjustment. The whole process is mechanically automatic, reducing manual intervention. This not only improves the work efficiency of the material feeding auxiliary process and reduces labor costs, but also avoids the errors and uncertainties of manual operation through stable and precise mechanical movements, ensuring production consistency.

[0074] Reference Figure 1 , Figure 2 , Figure 7 and Figure 8 In a preferred embodiment, the foam bag roll-end pusher assembly 18 includes:

[0075] The wound fabric 1801 is positioned above the feeding rack 5;

[0076] The auxiliary lifting component 1816 is located inside the automatic conveyor table 2 on the side near the feeding auxiliary frame 1, and the bottom end of the auxiliary lifting component 1816 is fixedly connected to the top end of the feeding frame 5.

[0077] The rotating rod 1808 is located inside the auxiliary lifting member 1816, and the outer side of the rotating rod 1808 is fixedly connected to one end of the wound cloth 1801 near the auxiliary lifting member 1816.

[0078] The pusher plate 1815 is located on the side of the auxiliary lifting component 1816 near the loading auxiliary frame 1.

[0079] In this invention, the foam bag roll-up and push assembly 18 further includes:

[0080] Two upper plate frames 1805 are fixedly connected to the top of the side of the feeding frame 5 near the feeding auxiliary frame 1;

[0081] Both annular seats 1802 are located inside the upper plate frame 1805, and the bottom ends of the annular seats 1802 are fixedly connected to the top end of the feeding frame 5.

[0082] Two winding motors 1803 are fixedly connected to the inner side of the annular seat 1802, and the power output shafts of the winding motors 1803 are connected to the winding shaft 1804 through a coupling.

[0083] Two gear guide seats 1807 are fixedly connected to both sides of the feeding rack 5;

[0084] Two rotating gears 1809 are fixedly connected to the outer ends of the rotating rod 1808. The rotating gears 1809 and the gear guide seat 1807 are meshed through tooth grooves.

[0085] In this invention, both ends of the rotating rod 1808 are movably connected to an outer shell 1810. The rotating gears 1809 are all located inside the outer shell 1810. A pull seat 1811 is fixedly connected to the side of the outer shell 1810 near the winding motor 1803. An electric telescopic rod 1812 is fixedly connected to the top of the pull seat 1811. Two spring rods 1813 are fixedly connected to the top of the pull seat 1811. An upper part 1814 is fixedly connected to the top of the spring rods 1813 and the electric telescopic rod 1812. The bottom end of the upper part 1814 is fixedly connected to the top of the push plate 1815. A pull rope 1806 is fixedly connected to the side of the pull seat 1811 near the winding motor 1803. The end of the pull rope 1806 away from the push plate 1815 is fixedly connected to the outside of the winding shaft 1804.

[0086] Specifically, when the winding motor 1803 starts, the power output shaft drives the winding shaft 1804 to rotate via a coupling. Since the pulling rope 1806 is wound around the outside of the winding shaft 1804, the pulling rope 1806 is gradually wound up as the winding shaft 1804 rotates, generating a horizontal pulling force on the pulling seat 1811. The pulling seat 1811, under the pulling force of the pulling rope 1806, drives the outer shell 1810, which is fixed to it, to move horizontally along the direction of the loading rack 5. The rotating gear 1809 inside the outer shell 1810 meshes with the gear guide seat 1807 through two tooth grooves (the gear guide seat 1807 is fixed to the upper...). On both sides of the material rack 5, there are meshing tracks for the rotating gear 1809. When the outer shell 1810 moves, the rotating gear 1809 rolls along the gear guide seat 1807, which in turn drives the rotating rod 1808 to rotate synchronously. One end of the winding cloth 1801 is fixed on the outside of the rotating rod 1808. When the rotating rod 1808 rotates, the winding cloth 1801 is gradually wound onto the rotating rod 1808, realizing the winding action of the tail end of the foam bag, gradually gathering and rolling up the tail end of the bag, so that the tail end of the bag is wrapped by the winding cloth 1801 and lifted and rolled up with the rotation of the rotating rod 1808. The telescopic rod of the retracting rod 1812 retracts, and with the elastic cushioning of the spring rod 1813, it drives the upper part 1814 and the pusher plate 1815 fixed thereto to move in the direction of the wrapping angle of the bag tail end. The pusher plate 1815 needs to be precisely aligned with the bag tail end rolled up by the winding cloth 1801, adjusted to a suitable height and angle, and contact the bag tail end area. After the pusher plate 1815 contacts the bag tail end, it continues to apply a pushing force, which, together with the winding cloth 1801, makes the bag tail end lift and tighten, squeezing and pushing the foam in the bag towards the annular pipe 6. The pusher plate 1815 pushes from one side. When a pushing force is applied, the foam material is pushed from the beginning of the bag to the annular pipe 6, completing the foam material ejection and unloading action. After the foam material ejection and unloading is completed, the winding motor 1803 reverses, the winding shaft 1804 rotates in the opposite direction, and the pull rope 1806 is released. Under the reverse pull of the pull rope 1806 (or the reset assistance of the spring rod 1813 and the electric telescopic rod 1812), the outer shell 1810, the rotating gear 1809, and the rotating rod 1808 return to their initial positions. The winding cloth 1801 then unfolds and resets, preparing for the next winding of the bag end. The staff removes the bag without foam material.

[0087] In actual operation, the pusher plate 1815, in conjunction with the rolled tail state, squeezes the foam material from a specific angle. Compared with pushing the material directly without a rolled tail, it can reduce foam material residue, control the feeding direction (such as precise guidance of the annular pipe 6), and allow the foam material to enter the subsequent work station more smoothly and in a more concentrated manner, thereby improving feeding efficiency and stability.

[0088] It should be noted that the flexible roll tail of the 1801 winding fabric, compared with the rigid clamp roll bag, can reduce bag wear and tear, and is especially suitable for thin bags and fragile bags; the push plate 1815 applies force evenly, avoiding local squeezing that damages the bag or crushes the foam.

[0089] Reference Figures 1-4 In a preferred embodiment, a linear travel seat 7 is fixedly connected inside the side of the feeding auxiliary frame 1 near the automatic conveyor table 2. A sliding seat 8 is slidably connected to the bottom end of the linear travel seat 7, and the bottom end of the sliding seat 8 is fixedly connected to the top end of the cutting blade 9. An arc-shaped anti-splash plate 10 is fixedly connected to the top end of the annular pipe 6. Multiple external frames 12 are fixedly connected to both sides of the automatic conveyor table 2. Telescopic electric rods 13 are fixedly connected to the opposite side of each external frame 12. Multiple rectangular holes are opened on both sides of the automatic conveyor table 2. The telescopic electric rods 13 are all located inside the rectangular holes. Multiple rectangular holes are opened on both sides of the automatic conveyor table 2. Moving rods 14 are slidably connected inside the rectangular holes. A fixing plate 16 is fixedly connected to the opposite side of each of the multiple telescopic electric rods 13 and the moving rods 14. Multiple adjusting springs 15 are fixedly connected to the opposite side of each fixing plate 16. An adjusting plate 17 is fixedly connected to the opposite side of each adjusting spring 15.

[0090] Working principle: The staff places the bag containing foam material on the conveyor belt 3 of the automatic conveyor table 2. The positioning control device 4 detects the position of the bag in real time. If the bag deviates from the center of the conveyor belt 3, the telescopic electric rods 13 on both sides of the automatic conveyor table 2 are activated. Through the external frame 12, the adjusting plate 17 is extended (the adjusting spring 15, the fixed plate 16, and the moving rod 14 work together to ensure the elastic adjustment of the adjusting plate 17). The bag is pushed from both sides to correct it to the center position of the conveyor belt 3, preparing for subsequent precise conveying.

[0091] When the conveyor belt 3 starts, it drives the bag to be conveyed towards the clamp-type bag adjustment component 11 and the foam bag roll-tail push component 18. The bag first passes through the auxiliary lifting component 1816 of the foam bag roll-tail push component 18. The auxiliary lifting component 1816 supports the bag so that the surface of the bag comes into contact with the winding cloth 1801 (the winding cloth 1801 is initially laid flat or pre-wound). At the same time, the first end of the bag gradually enters the area between the two moving plates 1105 of the clamp-type bag adjustment component 11, and the tail end approaches the winding position of the winding cloth 1801.

[0092] After the bag head enters between the two moving plates 1105, the bidirectional motor 1103 starts, driving the threaded rod 1102 to rotate, causing the sliding plate 1108 to bring the moving plates 1105 closer to each other. The clip 1113 moves with the moving plate 1105, puncturing the bag head and embedding into the hole groove of the bottom buckle plate 1115. Under the action of the compression spring 1112, the squeezing plate 1114 elastically squeezes the bottom buckle plate 1115, fixing the two sides of the bag head and leaving a channel for the foam to fall in the middle. If it is necessary to adjust the feeding angle, the drive motor 1110 starts, the gear plate 1111 rotates, and the arc gear rotating plate 1109 drives the moving plate 1105 and the bag head clamped to swing in an arc shape, adjusting the bag tilt angle so that the foam falls more smoothly towards the annular pipe 6.

[0093] The cutting blade 9 slides along the linear travel seat 7 to cut the surface of the bag head that has been clamped and fixed (in conjunction with the clamping assembly, it expands the foam drop channel), making it easier for the foam to fall from the head to the annular pipe 6. The arc-shaped splash guard 10 can prevent the foam from splashing and ensure that the foam falls accurately into the pipe.

[0094] The winding motor 1803 starts, the winding shaft 1804 rotates, the winding pull rope 1806 is wound, which drives the pull seat 1811 and the outer shell 1810 to move horizontally. The rotating gear 1809 inside the outer shell 1810 meshes with the gear guide seat 1807 and rotates, so that the rotating rod 1808 rotates synchronously. The winding cloth 1801 gradually winds the tail end of the bag, gathers and compresses the space of the foam in the bag, and assists the foam to fall to the head end. The electric telescopic rod 1812 starts, which drives the pusher plate 1815 to press down (spring rod 1813 elastically buffers). The pusher plate 1815 contacts the tail end of the bag gathered by the winding cloth 1801 and applies a pushing force. With the help of the channel in the head end clamping area, the foam is pushed from the head end of the bag into the annular pipe 6, completing the foam discharge.

[0095] The foam material is fed from the beginning of the bag to the annular pipe 6 through the coordinated action of the clamping assembly and the pushing assembly. It is then transported from the top layer (the initial bag conveying layer, i.e. the layer where the automatic conveyor 2 is located) to the second to last layer.

[0096] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
