DETAILED DESCRIPTION
[0018] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0019] like Figure 1 As shown in FIG. 2 , an embodiment of the utility model proposes an automatic feeding cardboard creasing device, comprising a workbench 1, mounting columns 2 are symmetrically arranged on both sides of the workbench 1, a lifting plate 3 is arranged between the two mounting columns 2, a cylinder 4 is fixedly arranged on the top of the lifting plate 3, an output end of the cylinder 4 vertically downward passes through the lifting plate 3 and is fixedly arranged with a mounting plate 5, a plurality of creasing strips 6 are arranged on the bottom of the mounting plate 5, a conveying trough is opened on the top of the workbench 1, a conveyor belt 7 is arranged in the conveying trough, a placing table 8 is also connected to one side of the workbench 1, limiting columns 9 are arranged at the four corners of the top of the placing table 8, two limiting columns 9 close to the workbench 1 are opened on the discharging ports for discharging cardboard, a pushing component for pushing the cardboard on the placing table 8 to the workbench 1 is arranged at the bottom of the placing table 8, and a correction plate 10 for correcting the angle of the cardboard pushed to the workbench 1 is also arranged on the top of the workbench 1. A plurality of cardboards are placed on the placement table 8. In this embodiment, the placement table 8 is connected to the workbench 1 by an inclined plate, so that the cardboard can be accelerated by the inclined plate when it comes out of the placement table 8, and can slide onto the workbench 1 more smoothly. During operation, a plurality of cut cardboards are stacked on the placement table 8 in advance, and then the pushing component is started, and the pushing component intermittently pushes the cardboards on the placement table 8 to the workbench 1. During this process, the correction plate 10 corrects the angle of the cardboard to prevent the cardboard from being skewed. After the conveyor belt 7 on the workbench 1 receives the cardboard, it pushes the cardboard to the workbench 1. The board is transported to the bottom of the mounting plate 5, and then the cylinder 4 is started. The cylinder 4 pushes the mounting plate 5 downward, so that the indentation strip 6 on the mounting plate 5 is pressed against the cardboard, thereby forming an indentation on the top of the cardboard. After the indentation is completed, the conveyor belt 7 transports the cardboard away. At this time, the pushing component pushes another piece of cardboard to the workbench 1, and is transported to the bottom of the mounting plate 5 again under the conveyor belt 7. This reciprocating process does not require workers to continuously place cardboard. The pushing component will intermittently push the cardboard to the workbench 1, realizing the automatic feeding of cardboard and reducing the labor intensity of workers. It should be noted that a person skilled in the art can set a sensor on the device to detect the position of the cardboard as needed, so as to stop the conveyor belt 7 and enable the cylinder 4 to perform the indentation operation on the cardboard.
[0020] like Figure 2—3, further, the pushing assembly includes: a vertical plate 11, a through groove is opened in the middle of the placing table 8, there are four vertical plates 11, the vertical plates 11 are symmetrically arranged in pairs at the bottom of the placing table 8 and on both sides of the through groove, a roller is rotatably provided between the two vertical plates 11, a belt 12 is sleeved on the two rollers, a pushing block 13 is fixedly provided on the outer surface of the belt 12, a pushing bar 14 is provided on the top of the pushing block 13, and a first motor 15 for driving the roller to rotate is also provided on one of the vertical plates 11. Specifically, the conveyor belt 7 is located directly below the through slot, and the width of the pushing block 13 is smaller than the width of the through slot, so that the pushing block 13 can intermittently enter the through slot and move along the length direction of the through slot. When the cardboard on the placement table 8 needs to be pushed onto the workbench 1, the first motor 15 is started, and the first motor 15 drives the roller to rotate, so that the belt 12 drives the pushing block 13 to make a rotational motion, so that the pushing block 13 enters the through slot until the top surface of the pushing strip 14 is horizontal, and the side wall of the pushing strip 14 contacts the side wall of the cardboard, so that the pushing strip 14 pushes the cardboard to move toward the workbench 1, until the cardboard is discharged from the discharge port of the limiting column 9 onto the workbench 1 as a whole. Furthermore, the end of the through slot away from the workbench 1 is in an arc-shaped expansion shape. Specifically, in the present embodiment, the movement direction of the push block 13 is clockwise, and the opening of the end of the through slot of the placement table 8 that first contacts the push block 13 is in an arc shape. In this way, once the belt 12 or the push block 13 becomes skewed, the arc-shaped structure can guide the push block 13 so that the push block 13 can smoothly enter the through slot to avoid hitting the side wall of the placement table 8 and causing damage to the device.
[0021] like Figure 2 and 4 As shown, further, a plurality of mounting boxes 16 are provided at the bottom of the mounting plate 5, a slide groove is provided at the bottom of each mounting box 16, a pressure strip 17 is slidably provided in each slide groove, and a spring 18 is provided between each pressure strip 17 and the inner wall of the corresponding mounting box 16. Specifically, the mounting box 16 is fixedly connected to the bottom plate, the height of the mounting box 16 is lower than the height of the indentation strip 6, and the height of the pressing strip 17 after extending out of the mounting box 16 is greater than the height of the indentation strip 6. When the mounting plate 5 is pressed down to press the indentation strip 6 on the cardboard, if the pressure is too great or the indentation is too deep, the indentation strip 6 may be embedded in the indentation, which may seriously cause the pressing plate to follow the mounting plate 5 to rise, affecting the subsequent processing of the cardboard. By providing the mounting box 16, the spring 18 and the pressing strip 17, when the indentation strip 6 indents the cardboard, the pressing strip 17 will be pressed on the cardboard under the push of the spring 18. At this time, the pressing strip 17 can prevent the edge of the cardboard from curling up. After the indentation is completed, the pressing strip 17 will push the cardboard and the indentation strip 6 to separate under the action of the spring 18, thereby avoiding the indentation strip 6 from being embedded in the indentation when the pressure is too great, thereby ensuring the smooth operation of the device.
[0022] like Figure 2 and4 As shown, further, mounting grooves are provided on the opposite sides of the two mounting columns 2, and both ends of the lifting plate 3 are slidably connected to the mounting grooves. A screw rod 19 is vertically and rotatably provided in one of the mounting grooves, and the screw rod 19 is threadedly connected to the lifting plate 3. After one end of the screw rod 19 passes through the mounting groove, a second motor 20 is provided to drive the screw rod 19 to rotate. In this embodiment, a guide rod can be provided in the mounting groove where the screw rod 19 is not installed, and the guide rod is slidably connected to the lifting plate 3 to guide the lifting and lowering of the lifting plate 3. The second motor 20 is fixedly provided on the top of one of the mounting columns 2. When the cardboards of different thicknesses are crimped, the second motor 20 is started, and the second motor 20 drives the screw rod 19 to rotate, and the screw rod 19 drives the lifting plate 3 threadedly connected thereto to rise or fall in the vertical direction, so that when the cylinder 4 pushes the mounting plate 5 downward, the crimping strip 6 can crimp cardboards of different thicknesses. As another embodiment, the second motor 20 can be directly used to drive the lifting plate 3 to rise or fall so that the mounting plate 5 can be raised or lowered to perform the creasing operation on the cardboard, which can save the cost of a cylinder 4, but will greatly consume the service life of the screw rod 19.
[0023] like Figure 2 and 4 As shown, further, a support plate 21 is horizontally and fixedly provided in the conveying trough. Specifically, the support plate 21 is located between the upper and lower surfaces of the conveyor belt 7 and is located directly below the mounting plate 5. The support plate 21 can support the upper surface of the conveyor belt 7, so that when the mounting plate 5 is pressed down onto the cardboard on the conveyor belt 7, the mounting plate 5 is pressed against the support plate 21, so that the conveyor belt 7 is prevented from being dented, and the indentation strip 6 makes a clear indentation on the cardboard.
[0024] like Figure 1 As shown, further, the correction plate 10 is in an isosceles trapezoidal structure. In this embodiment, there are two correction plates 10, which are symmetrically arranged on the top of the workbench 1. The correction plates 10 are in an isosceles trapezoidal shape, so that the cardboard is gradually guided to the middle position of the conveyor belt 7 when it is pushed onto the workbench 1, effectively avoiding the situation where the creasing strip 6 is skewed when creasing the cardboard.
[0025] like Figure 1 and 4 As shown, further, a guide column 22 is provided on the top of the mounting plate 5, and one end of the guide column 22 passes through the lifting plate 3 and is slidably connected to the lifting plate 3. When the cylinder 4 pushes the mounting plate 5 to move downward, the guide column 22 can guide the movement of the mounting plate 5.
[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
