Description

Technical Field

[0001] This invention relates to the field of washing machine production equipment technology, specifically a washing machine inner drum rolling machine. Background Technology

[0002] During the manufacturing process of a washing machine, the steel coil is first cut into a fixed length, then punched. After punching, the plate-shaped material is rolled into a circle and the two ends are joined together. The joint is then hinged, riveted, or welded.

[0003] A search revealed that patent application number CN202220588185.2 discloses a method in which a sheet material passes between a fixed pressure roller and a moving pressure roller, and a third drive mechanism drives the first and second rolling rollers to roll the sheet material into an arc shape. The addition of radial and axial positioning mechanisms ensures that the positional accuracy of the rolled material meets the gripping requirements of the robot arm, enabling automatic connection with other automated equipment.

[0004] However, the above-mentioned device requires the inner drum to be removed after rolling during the gap between the two sheet materials, and then the cut sheet materials are transported to the rolling equipment. This process takes too long. After each time the rolling equipment rolls the sheet materials, it needs to wait for a long time before it can roll again, which reduces the production efficiency of the washing machine inner drum. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a washing machine inner drum rolling machine, which solves the problem of excessively long feeding waiting time and reduced production efficiency of the washing machine inner drum.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a washing machine inner drum rolling machine, including a base plate, a back plate fixedly connected to the top of the base plate, a riveting assembly installed on one side of the back plate, side plates fixedly connected to both ends of the top of the base plate, a feeding assembly installed between the two sides of the side plates, and a rolling assembly installed at one top end of one side of the side plate.

[0007] The feeding assembly includes a rotating rod rotatably connected to the side plate. The rotating rod is covered by a multi-frame, and multiple round rods are fixedly connected to the outside of the rotating rod. A spring is fixedly connected between the round rods and the multi-frame. An electromagnet with one end extending into the outside of the multi-frame is fixedly connected to the outside of the multi-frame. A motor for driving the rotating rod to rotate is fixedly connected to one side of the side plate.

[0008] Preferably, the riveting assembly includes a horizontal plate fixedly connected to a back plate, a first hydraulic cylinder fixedly connected to the bottom of the horizontal plate, a riveting machine fixedly connected to the bottom of the first hydraulic cylinder, a metal ring fixedly connected to one side of the back plate, an arc-shaped pad fixedly connected to the top of the metal ring, and longitudinal plates fixedly connected to both ends of the bottom of the arc-shaped pad.

[0009] Preferably, the rolling assembly includes a folded plate fixedly connected to the side plate and extending into the interior of the multi-frame, an arc-shaped extrusion plate rotatably connected to the top of the folded plate, a second hydraulic cylinder penetrating its surface fixedly connected to the bottom of the folded plate, and a sliding plate rotatably connected to the output end of the second hydraulic cylinder.

[0010] Preferably, a transverse block is fixedly connected to the side of the longitudinal plate away from the metal ring, an annular plate is fixedly connected to one end of the transverse block, and a plurality of guide rods penetrating into the outer side of the annular plate are fixedly connected to the outer side of the annular plate.

[0011] Preferably, both ends of the rotating rod are fitted with battery packs for powering the electromagnet, and the battery packs are electrically connected to the electromagnet by wires. An inclined rod is fixedly connected to the side of the electromagnet near the rotating rod, and a limiting ring for restricting the movement path of the wires is fixedly connected between the inclined rods. The wires are slidably connected to the limiting rings.

[0012] Preferably, both ends of the multi-frame are fixedly connected to arc-shaped guide plates, and both ends of the arc-shaped guide plates near the multi-frame are fixedly connected to arc-shaped limiting blocks.

[0013] Preferably, a receiving box is fixedly connected to the top of the base plate, an elastic metal plate is fixedly connected to the bottom inner side of the receiving box, and a receiving plate is fixedly connected to the top of the elastic metal plate, with the receiving plate being inclined.

[0014] Preferably, a swing plate with one end extending into the interior is rotatably connected to one side of the receiving box, a driven plate is fixedly connected to the end of the swing plate near the multi-frame, and multiple rubber plates are fixedly connected to the side of the driven plate away from the swing plate.

[0015] Compared with the prior art, the present invention provides a washing machine inner drum rolling machine, which has the following beneficial effects:

[0016] 1. The feeding component can automatically discharge material after the inner drum is rolled and riveted. The feeding component is also controlled to shift downward to pick up the material. The plate-shaped material is controlled to stay on one side of the rolling component to wait for feeding. The processes of picking up material, waiting for feeding, and discharging are all carried out simultaneously after the inner drum is rolled. This reduces the waiting time between discharging and feeding the inner drum after rolling. The connection between the two inner drums is smoother, which improves the efficiency of the inner drum rolling.

[0017] 2. The guide rod can guide the discharge direction of the washing machine inner drum after it is rolled and riveted, so as to realize the automatic discharge of the washing machine inner drum.

[0018] 3. The rubber plate pushes the sheet material to the position between the arc-shaped limiting blocks, and at the same time, it rubs against the surface of the multi-frame, which improves the ability to correct the position during the feeding process and can reduce the possibility of misalignment when feeding raw materials.

Detailed Implementation

[0030] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0031] Example 1

[0032] Figures 1-6 In one embodiment of the present invention, a washing machine inner drum rolling machine includes a base plate 1, a back plate 2 fixedly connected to the top of the base plate 1, a riveting assembly 3 installed on one side of the back plate 2, side plates 4 fixedly connected to both ends of the top of the base plate 1, a feeding assembly 5 installed between the two sides of the side plates 4, and a rolling assembly 6 installed at one top end of one side of the side plates 4. Multiple perforated plate-shaped materials are stacked below the feeding assembly 5. After the feeding assembly 5 picks up the plate-shaped materials, it stays on one side of the riveting assembly 3 and waits. The inner drum that has been rolled and riveted on the riveting assembly 3 is removed. The feeding assembly 5 rotates 60° to the bottom of the riveting assembly 3. The rolling assembly 6 pushes the plate-shaped materials upward and bends them to complete the rolling. The riveting assembly 3 rivets and fixes the two ends of the plate-shaped materials together, and then removes them. This feeding, rolling and riveting process is repeated to complete the automatic rolling of the washing machine inner drum.

[0033] The feeding assembly 5 includes a rotating rod 51 rotatably connected to the side plate 4. A multi-frame 52 is fitted around the rotating rod 51. Multiple round rods 53 are fixedly connected to the outer side of the rotating rod 51. A spring 54 is fixedly connected between the round rods 53 and the multi-frame 52. An electromagnet 55 with one end extending into the outer side of the multi-frame 52 is fixedly connected to the outer side of the multi-frame 52. A motor 56 for driving the rotating rod 51 to rotate is fixedly connected to one side of the side plate 4. The motor 56 drives the rotating rod 51 to rotate, which in turn drives the multi-frame 52 to rotate via the round rods 53 and the spring 54. During rotation, the top of the multi-frame 52 contacts and presses against the bottom of the riveting assembly 3, pushing the spring 54 to contract and move downwards. One side of the bottom of the multi-frame 52 descends and gets closer to the plate-shaped material below. The electromagnet 55 attracts the plate-shaped material to move and press it tightly against the bottom side of the multi-frame 52. Then, as the multi-frame 52 rotates, when the edges of the multi-frame 52 pass the riveting assembly 3... When the multi-frame 52 no longer contacts the bottom of the riveting assembly 3, the retracted spring 54 pushes the multi-frame 52 to a position at the same distance from the rotating rod 51 until the multi-frame 52, which has absorbed the plate-shaped material, rotates to the bottom of the riveting assembly 3. The rolling assembly 6 and the riveting assembly 3 sequentially roll and rivet the plate-shaped material. During the rotation of the multi-frame 52, when the edges pass through the riveting assembly 3, it pushes the rolled and riveted inner drum to move away from the back plate 2. The inner drum is pushed out of the riveting assembly 3 to complete the discharge. It can automatically discharge the material after the inner drum is rolled and riveted, and control the position of the feeding assembly 5 to shift downward to pick up the material. It controls the plate-shaped material to stay on one side of the rolling assembly 6 to wait for feeding. The processes of picking up the material, waiting for feeding, and discharging are carried out simultaneously after the inner drum is rolled. This reduces the waiting time for the inner drum to be rolled and discharged and then fed again. The connection between the two inner drums is smoother, which improves the efficiency of the inner drum rolling.

[0034] The riveting assembly 3 includes a horizontal plate 31 fixedly connected to the back plate 2. A first hydraulic cylinder 32 is fixedly connected to the bottom of the horizontal plate 31. A riveting machine 33 is fixedly connected to the bottom of the first hydraulic cylinder 32. A metal ring 34 is fixedly connected to one side of the back plate 2. An arc-shaped pad 35 is fixedly connected to the top of the metal ring 34. Longitudinal plates 36 are fixedly connected to both ends of the bottom of the arc-shaped pad 35. After the plate-shaped material is rolled into a circle, the first hydraulic cylinder 32 pushes the riveting machine 33 down until the riveting machine 33 presses the two ends of the plate-shaped material onto the arc-shaped pad 35. The riveting machine 33 rivets and fixes the two ends of the plate-shaped material, thereby realizing the riveting and fixing of the rolled plate-shaped material.

[0035] The rolling assembly 6 includes a folded plate 61 fixedly connected to the side plate 4 and extending into the interior of the multi-frame 52. An arc-shaped extrusion plate 62 is rotatably connected to the top of the folded plate 61, and a second hydraulic cylinder 63 is fixedly connected to the bottom of the folded plate 61, penetrating its surface. A sliding plate 64 is rotatably connected to the output end of the second hydraulic cylinder 63. When the multi-frame 52 moves the sheet material to below the metal ring 34, the second hydraulic cylinder 63 pushes the arc-shaped extrusion plate 62 to rotate. After the arc-shaped extrusion plate 62 passes through the multi-frame 52, it extrudes the sheet material tightly onto the metal ring 34. After the sheet material adheres to the metal ring 34 to form a ring, both ends extend to the arc-shaped pad 35 to await riveting, thus realizing the rolling process of the sheet material after loading, waiting for the next riveting work.

[0036] Both ends of the rotating rod 51 are fitted with battery packs 10 for powering the electromagnet 55. The battery packs 10 and the electromagnet 55 are electrically connected by wires 11. An inclined rod 12 is fixedly connected to the side of the electromagnet 55 near the rotating rod 51. A limiting ring 13 is fixedly connected between the inclined rods 12 to restrict the movement path of the wires 11. The wires 11 and the limiting ring 13 are slidably connected. The battery pack 10 powers the electromagnet 55 to ensure that the electromagnet 55 is magnetic. During the rotation of the feeding assembly 5, the movement of the wires 11 is restricted by the limiting ring 13 to prevent the wires 11 from being blocked and pulled apart by the folding plate 61 and the second hydraulic cylinder 63 when they rotate to the highest point of the multi-frame 52.

[0037] Both ends of the multi-frame 52 are fixedly connected to arc-shaped guide plates 14. Both ends of the arc-shaped guide plates 14 near the multi-frame 52 are fixedly connected to arc-shaped limiting blocks 15. When the electromagnet 55 attracts the plate-shaped material to move and stick to the multi-frame 52, the plate-shaped material slides along the arc-shaped guide plates 14 onto the multi-frame 52, avoiding misalignment with the multi-frame 52 in the length direction. The plate-shaped material is positioned between the two sides of the arc-shaped limiting blocks 15, avoiding misalignment with the multi-frame 52 in the width direction. The positioning of the plate-shaped material can be completed during the feeding process. No other actions are required before rolling. Compared with common rolling equipment, which requires the removal of the positioning component after the plate-shaped material is positioned before rolling, this reduces the working process of the positioning component during rolling, reduces the time required for the positioning component to move, further speeds up the preparation work for rolling the inner drum of the washing machine, and improves the efficiency of rolling the inner drum of the washing machine.

[0038] Example 2

[0039] Reference Figures 1-9 Based on Embodiment 1, a transverse block 7 is fixedly connected to the side of the longitudinal plate 36 away from the metal ring 34. An annular plate 8 is fixedly connected to one end of the transverse block 7. Multiple guide rods 9 that penetrate into the annular plate 8 are fixedly connected to the outer side of the annular plate 8. When the multi-frame 52 rotates and pushes the rolled washing machine inner drum to move away from the back plate 2, the inner drum slides along the metal ring 34 onto the guide rods 9 and then slides along the guide rods 9 to discharge the material. This can guide the discharge direction of the rolled and riveted washing machine inner drum and realize the automatic discharge of the washing machine inner drum.

[0040] A receiving box 16 is fixedly connected to the top of the base plate 1. An elastic metal plate 17 is fixedly connected to the bottom inner side of the receiving box 16. A receiving plate 18 is fixedly connected to the top of the elastic metal plate 17. The receiving plate 18 is inclined. The inner drum of the washing machine, which slides along the guide rod 9, falls into the receiving box 16. The inner drum of the washing machine pushes the receiving plate 18 downward to squeeze and bend the elastic metal plate 17 for cushioning. Then, it slides along the inclined receiving plate 18 to the bottom end of the receiving box 16 to reduce the degree of deformation caused by the collision between the inner drum of the washing machine and the equipment when discharging.

[0041] A swing plate 19 extending into the interior is rotatably connected to one side of the receiving box 16. A driven plate 20 is fixedly connected to the end of the swing plate 19 near the multi-frame 52. Multiple rubber plates 21 are fixedly connected to the side of the driven plate 20 away from the swing plate 19. As the inner drum of the washing machine falls into the receiving box 16 and pushes the receiving plate 18 down, the receiving plate 18 pushes the swing plate 19 to rotate. The swing plate 19 drives the driven plate 20 and the rubber plates 21 to rotate. The rubber plates 21 push the plate-shaped material on the bottom side of the multi-frame 52 to move, pushing the plate-shaped material to the position between the arc-shaped limiting blocks 15. At the same time, the friction between the rubber plates 21 and the surface of the multi-frame 52 can clean up small particle obstacles on the surface of the multi-frame 52, preventing the plate-shaped material from being blocked and misaligned when it is attached to the surface of the multi-frame 52. This improves the ability to correct the position during the feeding process and reduces the possibility of misalignment when feeding raw materials.

[0042] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.
