Description

Technical Field

[0001] This embodiment relates to the field of profile processing technology, and in particular to a feeding rack and a feeding device including the feeding rack. Background Technology

[0002] Profile processing equipment, such as profile cutting machines, requires a feeding device for mass production. One feeding device includes multiple feeding racks, each comprising an inclined conveyor section and a horizontal conveyor section. During feeding, the profile is conveyed to the inclined conveyor section, where it slides or rolls under gravity to the horizontal conveyor section, finally reaching the bottom of the cutting machine, where a lifting device lifts it onto the cutting machine.

[0003] However, when feeding large-diameter pipes, this type of feeding device is prone to damage to the feeding rack due to its large weight and impact after a certain number of feeding cycles, and may even affect the cutting machine, posing a certain safety risk. Utility Model Content

[0004] The main purpose of this utility model is to propose a feeding rack, which aims to solve the technical problem of low safety when feeding large profiles in the existing feeding devices.

[0005] To achieve the above objectives, this utility model proposes a feeding rack, including a frame with a series of inclined feeding sections and a horizontal feeding section arranged on the frame. The inclined feeding section has a conveying slope that extends from top to bottom in the direction away from and towards the horizontal feeding section. The frame is equipped with a buffer device, which includes a material support structure and a buffer drive device connected by a transmission. The material support structure is movably disposed at the output end of the buffer drive device and can protrude from the conveying slope. The buffer drive device can drive the material support structure to move along the extension direction of the conveying surface, so that when feeding, the profile on the conveying slope is supported on the material support structure. The buffer drive device drives the material support structure and the profile to move along the conveying slope and approach the horizontal feeding section until the profile is supported on the horizontal feeding section.

[0006] The beneficial effects of this utility model are as follows: When the feeding rack of this utility model is feeding, the buffer drive device drives the material support structure to support the profile, reducing the moving speed of the profile on the conveying slope and conveying it to the flat conveying part. This helps to reduce the impact force of the profile on the flat conveying part, protect the feeding rack, extend the service life of the feeding rack, and improve safety.

[0007] Preferably, the buffer drive device includes a buffer cylinder, the cylinder body of which is fixed to the side of the frame, the extension direction of the piston rod of the buffer cylinder is parallel to the extension direction of the conveying inclined plane, and the material support structure is located at the upper end of the piston rod.

[0008] Preferably, the material support structure includes a rotary cylinder and a material support bar. The rotary cylinder is located at the upper end of the piston rod of the buffer cylinder, and the material support bar is perpendicular to the piston rod of the buffer cylinder. One end of the material support bar is driven to the output end of the rotary cylinder. The rotary cylinder can drive the material support bar to swing, so that the end of the material support bar away from the rotary cylinder protrudes out of the conveying slope to support the profile on the conveying slope.

[0009] Preferably, it also includes a material blocking device, which corresponds to the position of the conveying inclined surface. The material blocking device includes a material blocking drive device and a material blocking component. The material blocking drive device is mounted on the frame and can drive the material blocking component to protrude out of the conveying inclined surface to restrict the profile on the conveying inclined surface from moving downward along the conveying inclined surface.

[0010] Preferably, the device further includes a screening device, which includes a first pushing device that corresponds to a blocking device. The first pushing device includes a first pushing drive device and a mounting plate that are connected by a transmission. The first pushing drive device can drive the mounting plate to move along the extension direction of the conveying slope. The mounting plate is provided with a lifting cylinder, and a pushing structure is connected to the lifting cylinder by a transmission. The lifting cylinder can drive the pushing structure to protrude out of the conveying slope. During screening, the lifting cylinder lifts the pushing structure to protrude out of the conveying slope. The first pushing drive device drives the mounting plate to move upward along the conveying slope to push multiple profiles blocked on the conveying slope by the blocking device until only one profile can be accommodated between the blocking device and the upper end of the conveying slope in the direction along the conveying slope.

[0011] Preferably, the screening device further includes a second pushing device, which is disposed on the pushing structure. The second pushing device includes a second pushing drive device and a second pushing component. The second pushing drive device can drive the second pushing component to move along the extension direction of the conveying slope. After the first pushing device screens the material, the second pushing drive device drives the second pushing component to push the stacked profiles out of the conveying slope.

[0012] Preferably, the flat conveying section is equipped with a flat conveying drive device and a flat conveying chain that are connected by a transmission. The flat conveying chain is wound around the frame, and multiple profile placement positions are arranged evenly on the flat conveying chain in sequence.

[0013] Preferably, it also includes a front frame, which is equipped with a feeding belt and a feeding tensioning structure. The feeding tensioning structure can drive the feeding belt to be tensioned and transport the profile to the conveying inclined surface.

[0014] This utility model also discloses a feeding device, including multiple feeding racks as described above, which are arranged sequentially and connected by transmission. Attached Figure Description

[0026] like Figures 1 to 5 As shown, a feeding rack 10 includes a frame 1, on which a sloping conveyor section 11 and a flat conveyor section 12 are arranged in sequence. The sloping conveyor section 11 is provided with a conveying inclined surface 111, which extends from top to bottom in the direction away from and close to the flat conveyor section 12. The frame 1 is provided with a buffer device 2, which includes a material support structure 22 and a buffer drive device 21 connected by transmission. The material support structure 22 is movably disposed at the output end of the buffer drive device 21 and can protrude from the conveying inclined surface 111. The buffer drive device 21 can drive the material support structure 22 to move along the extension direction of the conveying surface, so that when feeding, the profile on the conveying inclined surface 111 is supported on the material support structure 22. The buffer drive device 21 drives the material support structure 22 and the profile to move along the conveying inclined surface 111 and close to the flat conveyor section 12 until the profile is supported on the flat conveyor section 12.

[0027] In this embodiment, when the feeder 10 is feeding material, the buffer drive device 21 drives the material support structure 22 to support the profile, reducing the moving speed of the profile on the conveying ramp 111 and conveying it to the flat conveying section 12. This helps to reduce the impact force of the profile on the flat conveying section 12, protect the feeder 10, extend the service life of the feeder 10, and improve safety.

[0028] In some specific embodiments, reference is made to Figure 1 and Figure 2 The buffer drive device 21 includes a buffer cylinder 211. The cylinder body of the buffer cylinder 211 is fixed to the side of the frame 1. The extension direction of the piston rod of the buffer cylinder 211 is parallel to the extension direction of the conveying inclined surface 111. The material support structure 22 is located at the upper end of the piston rod.

[0029] With this configuration, the buffer cylinder 211 can drive the material support structure 22 to approach the upper end of the conveying inclined surface 111, thereby accommodating the feeding of profiles of more different specifications and expanding the scope of application.

[0030] In some specific embodiments, the material support structure 22 includes a rotary cylinder 221 and a material support bar 222. The rotary cylinder 221 is located at the upper end of the piston rod of the buffer cylinder 211. The material support bar 222 is perpendicular to the piston rod of the buffer cylinder 211. One end of the material support bar 222 is driven to be connected to the output end of the rotary cylinder 221. The rotary cylinder 221 can drive the material support bar 222 to swing, so that the end of the material support bar 222 away from the rotary cylinder 221 protrudes from the conveying inclined surface 111 to support the profile on the conveying inclined surface 111.

[0031] The rotary cylinder 221 can drive the material support bar 222 to swing. When the profile needs to be slowly moved downwards along the conveying slope 111, the rotary cylinder 221 swings the material support bar 222 so that the end of the material support bar 222 away from the rotary cylinder 221 is higher than the conveying slope 111, i.e., protruding from the conveying slope 111. After the profile is conveyed to the flat conveying section 12, the rotary cylinder 221 swings the material support bar 222 so that the end of the material support bar 222 away from the rotary cylinder 221 is lower than the upper side of the flat conveying section 12, so that the material support structure 22 will not obstruct the profile when it moves upwards along the conveying slope 111. This setting facilitates the posture change of the material support bar 222, helps to maintain the smooth progress of the feeding process, and improves the feeding efficiency.

[0032] In other embodiments, a motor can be used in combination with a lead screw, gear rack, or other structural forms, as long as the material support bar 222 can protrude from the conveying inclined surface 111 and retract to the upper side of the conveying section 12 below the conveying inclined surface 111.

[0033] In some specific embodiments, reference is made to Figure 3 and Figure 4 It also includes a material blocking device 3, which corresponds to the position of the conveying inclined surface 111. The material blocking device 3 includes a material blocking drive device 31 and a material blocking element 32. The material blocking drive device 31 is mounted on the frame 1. The material blocking drive device 31 can drive the material blocking element 32 to protrude out of the conveying inclined surface 111 to restrict the profile on the conveying inclined surface 111 from moving downward along the conveying inclined surface 111.

[0034] Specifically, the material blocking drive device 31 is a pusher drive cylinder, the cylinder body of which is mounted on the frame 1, and the piston rod extends in a direction perpendicular to the conveying inclined plane 111. The material blocking component 32 is strip-shaped and is fixedly mounted on the piston rod of the pusher drive cylinder.

[0035] During feeding, the blocking device 3 first blocks the profiles and then releases them in sequence, so that the profiles can be transported in an orderly manner on the feeding rack 10.

[0036] In some specific embodiments, reference is made to Figure 3 and Figure 4 It also includes a screening device, which includes a first pushing device 4, which corresponds to the blocking device 3. The first pushing device 4 includes a first pushing drive device 41 and a mounting plate 42 that are connected by transmission. The first pushing drive device 41 can drive the mounting plate 42 to move along the extension direction of the conveying slope 111. The mounting plate 42 is provided with a lifting cylinder 43, and the lifting cylinder 43 is connected by transmission to a pushing structure 44. The lifting cylinder 43 can drive the pushing structure 44 to protrude out of the conveying slope 111. When screening, the lifting cylinder 43 lifts the pushing structure 44 to protrude out of the conveying slope 111. The first pushing drive device 41 drives the mounting plate 42 to move upward along the conveying slope 111 to push multiple profiles blocked on the conveying slope 111 by the blocking device 3, until only one profile can be accommodated between the blocking device 32 and the upper end of the conveying slope 111 in the direction along the conveying slope 111.

[0037] Specifically, the first pushing drive device 41 includes a first pushing drive motor, a pushing rack, and a pushing gear. The first pushing drive motor is mounted on the frame 1, the pushing gear is mounted on the shaft of the first pushing drive motor, and the pushing rack is mounted on the lower side of the mounting plate 42. The pushing rack and the pushing gear are meshed together. The cylinder body of the lifting cylinder 43 is mounted on the mounting plate 42, the piston rod of the lifting cylinder 43 extends in a direction perpendicular to the conveying inclined plane 111, and the pushing structure 44 is mounted on the piston rod of the lifting cylinder 43.

[0038] After the tubular material is conveyed onto the conveying ramp 111, the distance between the baffle 32 and the upper end of the conveying ramp 111 may be sufficient to accommodate multiple profiles. If the excess profiles are not pushed out, multiple profiles will move down the conveying ramp 111 simultaneously when the pusher 32 descends, causing feeding chaos. In this embodiment, the first pusher device 4 is used to push the excess profiles out of the conveying ramp 111 after the baffle is closed, leaving only one profile between the baffle 32 and the upper end of the conveying ramp 111 along the direction of the conveying ramp 111. This arrangement helps to ensure the orderly feeding, maintain the normal operation of the feeding device, and improve production efficiency.

[0039] In some specific embodiments, reference is made to Figure 3 and Figure 4 The screening device also includes a second pushing device 5, which is mounted on the pushing structure 44. The second pushing device 5 includes a second pushing drive device 51 and a second pushing component 52. The second pushing drive device 51 can drive the second pushing component 52 to move along the extension direction of the conveying slope 111. After the first pushing device 4 screens the material, the second pushing drive device 51 drives the second pushing component 52 to push the stacked profiles out of the conveying slope 111.

[0040] Specifically, the pushing structure 44 is a box structure, and the second pushing structure 44 is located near the upper side of the pushing structure 44. The second pushing device 5 is a second pushing cylinder, the cylinder body of which is located inside the pushing structure 44. The piston rod of the second pushing cylinder extends along the direction of the conveying inclined plane 111, and a second pushing component 52, which is a second pushing plate, is provided on the piston rod. The second pushing cylinder can drive the second pushing plate to move to the outside of the pushing structure 44.

[0041] After the first pushing device 4 screens the material, although only one profile can be accommodated between the baffle 32 and the upper end of the conveying ramp 111 in the direction along the conveying ramp 111, it is possible for the profiles to stack. When this happens, the second pushing cylinder drives the second pushing plate to move to the outside of the pushing structure 44 and pushes the stacked profiles out of the conveying ramp 111, so that only one profile moves down the conveying ramp 111 after the baffle device is in the direction of the baffle. Then the pushing device 32 supports the profile and moves it onto the flat conveyor 12.

[0042] In some specific embodiments, reference is made to Figure 1 The flat conveying section 12 is equipped with a flat conveying drive device and a flat conveying chain 121 connected by transmission. The flat conveying chain 121 is wound around the frame 1, and multiple profile placement positions 1211 are evenly arranged on the flat conveying chain 121 in sequence.

[0043] In existing technologies, the length of the horizontal conveying section 12 is typically short, causing the inclined conveying section 11 to extend close to the cutting machine, making it inconvenient to avoid obstacles during installation. In this embodiment, the horizontal conveying section 12 is equipped with a horizontal conveying drive device and a horizontal conveying chain 121 connected by a transmission, allowing the length of the horizontal conveying section 12 to be set longer, making it easier for the loading rack 10 to avoid obstacles from the cutting machine.

[0044] In some specific embodiments, reference is made to Figure 2 It also includes a front frame 6, which is equipped with a feeding belt and a feeding tensioning structure 61. The feeding tensioning structure 61 can drive the feeding belt to be tensioned and transport the profile to the conveying inclined surface 111.

[0045] This embodiment also discloses a feeding device, see reference. Figure 5 It includes multiple feeding racks 10, which are arranged in sequence and connected by transmission.

[0046] The above description is only a preferred embodiment of this embodiment and does not limit the patent scope of this embodiment. All equivalent structural transformations made under the inventive concept of this embodiment using the description and drawings of this embodiment, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this embodiment.
