Description

Technical Field

[0001] This application relates to the field of cardboard cutting and processing, and in particular to a feeding anti-jamming mechanism for a board support or comb pushing mechanism. Background Technology

[0002] Corrugated cardboard production mainly uses computer-controlled slitting and trimming machines for cutting, which not only has high production efficiency but also high cutting accuracy. The cutting quality of corrugated cardboard by the computer-controlled slitting and trimming machine is mainly determined by the board support (comb) that cooperates with the cutting wheel. The more fully the board support supports the corrugated cardboard, the smaller the rough edges after cutting. During the cardboard cutting process, the cutting wheel engages between adjacent comb teeth to cut the cardboard.

[0003] Chinese utility model patent CN221756153U discloses a board tray or comb pushing device, relating to the field of cardboard cutting and processing. It includes a mounting base and a push block slidably connected to the mounting base. The mounting base has a board drop groove, and the push block slides closer to or away from the drop groove. The mounting base is equipped with a driving component to move the push block. When the comb teeth on the board tray / comb are worn, the driving component drives the push block to move closer to the drop groove. The speed and distance of the push block's movement can be adjusted according to actual needs, allowing the intact board tray / comb to move to the cutting wheel and engage with it. This eliminates the need to stop the machine to replace the board tray / comb, saving replacement time and reducing the impact on cardboard cutting efficiency. Furthermore, the same batch of board trays / combs can be reused multiple times among multiple computerized slitting and trimming machines, improving the utilization rate of the board trays / combs.

[0004] In actual use, when the plate support needs to be replaced after wear, the drive pusher causes the plate support to slide from the feeding end to the unloading end, causing one plate support near the unloading end to detach from the mounting base. During the detachment process, the edge of the plate support may get stuck on the mounting base, which prevents subsequent plate supports from being unloaded. Production can only continue after manual unloading, affecting production efficiency. Utility Model Content

[0005] In order to prevent the plate holder that needs to be unloaded from getting stuck on the mounting base, this application provides an anti-jamming mechanism for unloading plate holders or comb pushing mechanisms.

[0006] This application provides a material feeding anti-jamming mechanism for a plate support or comb pushing mechanism, which adopts the following technical solution:

[0007] A feeding anti-jamming mechanism for a plate support or comb pushing mechanism includes a mounting base and a guide rail disposed on the mounting base for sliding of a plurality of plate supports. One end of the guide rail is a feeding end and the other end is a feeding end. A feeding zone for the plate supports to fall is provided on the side of the feeding end away from the feeding end on the mounting base. The mechanism also includes a driving mechanism for driving the plate supports in the feeding zone to detach from the mounting base.

[0008] By adopting the above technical solution, the board tray in this solution can be replaced by a comb. The board tray or comb pushing mechanism is installed on the computer slitting and trimming machine. When the board tray needs to be replaced after wear, the worn board tray is unloaded. The board tray slides from the loading end along the unloading section. When the board tray is removed from the guide rail, the drive mechanism works to drive the board tray to fall off the mounting seat, ensuring the unloading of the board tray. The board tray that needs to be unloaded is not easy to get stuck on the mounting seat. There is no need to manually remove the board tray from the mounting seat, which is not likely to affect the production of cardboard.

[0009] Optionally, the driving mechanism is a driving cylinder, which drives the plate support to detach from the mounting base.

[0010] By adopting the above technical solution, when the plate support slides towards the unloading area and is about to detach from the mounting seat, the piston shaft of the drive cylinder pushes the plate support and removes it from the mounting seat, preventing the plate support from getting stuck in the mounting seat.

[0011] Optionally, a push block is provided on the output end of the drive cylinder. The area of ​​the push block is larger than the area of ​​the piston at the output end of the drive cylinder. The drive cylinder drives the push block to abut against the plate support to push the plate support away from the mounting seat.

[0012] By adopting the above technical solution, when the plate support is stuck on the mounting base at different angles (such as when the side is raised), the contact area of ​​the push block is large, and the push block can easily contact the plate support to make the plate support detach from the mounting base.

[0013] Optionally, the driving mechanism includes an air blowing component, which blows air towards the unloading area, and blows the plate support away from the mounting base.

[0014] By adopting the above technical solution, the air blowing component blows air towards the unloading area, and the air blowing component detaches the plate support from the mounting base. The air blowing component is small in size and easy to install. The air blowing method does not require contact with the plate support. By adjusting the air pressure and flow rate, the magnitude of the blowing force can be precisely controlled, which can ensure that the plate support falls into the unloading area and avoid excessive impact force from damaging the plate support.

[0015] Optionally, when the plate support is detached from the mounting base, the air blowing element blows air upward toward the end of the plate support.

[0016] By adopting the above technical solution, the air blowing component blows air upward toward the end of the plate support, which facilitates the plate support to detach from the mounting base and makes it easier for the plate support to fall into the unloading area.

[0017] Optionally, when the plate holder is detached from the mounting base, the air blowing element blows air in a horizontal direction and perpendicular to the length direction of the guide rail.

[0018] By adopting the above technical solution, the air blowing component blows air in the horizontal direction and perpendicular to the length of the guide rail, which facilitates the plate support to detach from the mounting base and makes it easier for the plate support to fall into the unloading area.

[0019] Optionally, the guide rail is provided with a receiving groove for the plate support to slide, the plate support is slidably connected to the receiving groove, the end of the plate support is provided with an anti-detachment block, and the receiving groove is provided with anti-detachment grooves on opposite side walls for the anti-detachment block to slide.

[0020] By adopting the above technical solution, the anti-detachment block and anti-detachment groove make the plate support slide stably and it is not easy to detach from the guide rail during sliding.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. When the tray needs to be replaced after wear, the drive mechanism drives the tray to detach from the mounting base to prevent the tray from getting stuck on the mounting base during the detachment process. The tray that needs to be unloaded is less likely to get stuck on the mounting base, which will not affect the production of cardboard.

[0023] 2. The push block has a large contact area with the plate support, making it easy for the push block to detach the plate support from the mounting base;

[0024] 3. The air blowing component can be set with multiple air outlet directions, making it easy for the plate support to detach from the mounting base. Attached Figure Description

[0031] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0032] Example 1

[0033] Embodiment 1 of this application discloses a material feeding anti-jamming mechanism for a plate support or comb pushing mechanism. (See also...) Figure 1 , Figure 2 The unloading anti-jamming mechanism of the plate support or comb pushing mechanism includes a mounting base 1 and a guide rail 3 fixed on the mounting base 1 for sliding of several plate supports 2. One end of the guide rail 3 is the loading end and the other end is the unloading end. The mounting base 1 is provided with a unloading section 4 on the side of the unloading end away from the loading end for the plate supports 2 to fall.

[0034] Reference Figure 1 , Figure 2 Push plates 81 are slidably connected to both sides of the mounting base 1. Two electric push rods 82 are fixed on the mounting base 1. The electric push rods 82 correspond one-to-one with the push plates 81. The electric push rods 82 drive the push plates 81 to press against a row of plate supports 2. The guide rail 3 is provided with a receiving groove 62 for the plate supports 2 to slide. The plate supports 2 are slidably connected to the receiving groove 62. The plate supports 2 slide along the length of the guide rail 3. The end of the plate supports 2 is fixed with an anti-detachment block 71. The receiving groove 62 is provided with anti-detachment grooves 72 on the opposite side walls for the anti-detachment block 71 to slide.

[0035] Reference Figure 1 , Figure 2 , Figure 3 The feeding anti-jamming mechanism of the plate support or comb pushing mechanism also includes a drive mechanism 5, which is used to drive the plate support 2 in the feeding section 4 to detach from the mounting base 1. The drive mechanism 5 is a drive cylinder 51, which drives the plate support 2 to detach from the mounting base 1. The drive cylinder 51 can be a pneumatic cylinder, an electric push cylinder, or a hydraulic cylinder. In this embodiment, the drive cylinder 51 is an electric push cylinder 511. Support frames are provided on both sides of the mounting base, and a support block is provided on one side of the support frame. The electric push cylinder 511 is fixed on the support block, and a push block 61 is fixed on the output end of the electric push cylinder 511. The area of ​​the push block 61 is larger than the area of ​​the piston at the output end of the electric push cylinder 511. The electric push cylinder 511 drives the push block 61 to abut against the plate support 2 to push the plate support 2 to detach from the mounting base 1.

[0036] The implementation principle of the anti-jamming mechanism for the board tray or comb pushing mechanism in Embodiment 1 of this application is as follows: The board tray 2 in this solution can be replaced by a comb. When the board tray 2 needs to be replaced after wear, the worn board tray 2 is unloaded. The board tray 2 slides from the loading end along the unloading section 4. The electric push rod 82 drives the push plate 81 at the loading end to slide closer to the unloading end. The push plate 81 near the unloading end slides away from the loading end. When the board tray 2 is separated from the guide rail 3, the electric push cylinder 511 drives the push block 61 to abut against the board tray 2 to push the board tray 2 away from the mounting seat 1. After the board tray 2 is separated from the mounting seat 1, it falls into the unloading section 4. The board tray 2 that needs to be unloaded is not easy to get stuck on the mounting seat 1. There is no need to manually remove the board tray 2 from the mounting seat 1, which is not likely to affect the production of cardboard.

[0037] Example 2

[0038] Reference Figure 4 The difference between this embodiment and Embodiment 1 is that the driving mechanism 5 includes an air blowing component 52. The air blowing component 52 blows air towards the unloading area 4, and blows the plate support 2 away from the mounting base 1. In this embodiment, the air blowing component 52 is an air outlet, which is used to connect to an air pipe. When the plate support 2 is detached from the mounting base 1, the air blowing component 52 is fixed to one side of the mounting base 1. The length direction of the air blowing component 52 is not parallel to the length direction of the guide rail 3, and the air blowing component 52 blows air upward towards the end of the plate support 2. An air source device (not shown in the figure) is fixed to the air blowing component 52, and an air pipe is connected to the air source. The air blowing component 52 is connected to the air source device through the air pipe. The blowing component is small in size, low in cost, and easy to install. The air blowing method does not require contact with the plate support 2. The air pressure and flow rate are adjusted by the air source device to precisely control the magnitude and timing of the blowing force, ensuring that the plate support 2 falls into the unloading area 4.

[0039] Example 3

[0040] Reference Figure 5 The difference between this embodiment and embodiment 2 is that when the plate support 2 is detached from the mounting base 1, a connecting plate 93 is fixed on the side wall of the mounting base 1, and the air blowing component 52 is fixed on the connecting plate 93 and passes through the connecting plate 93. The air blowing component 52 blows air in the horizontal direction and perpendicular to the length direction of the guide rail 3.

[0041] The air blowing component 52 has two blowing angle directions. When the construction site is relatively open, the installation method of Example 3 is selected to blow air onto the plate support 2; when the construction site is relatively narrow, Example 2 is selected to blow air onto the plate support 2. Different blowing angles are selected according to different construction sites.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
