Description

Technical Field

[0001] The invention relates to the technical field of cardboard printing, and in particular to a convenient cardboard aligning device. Background Art

[0002] A carton printing machine is a printing device that can print the required text, patterns and other information onto the surface of a carton. It generally includes process flows such as plate mounting, inking, embossing, and paper feeding. Carton printing machines generally have single printing, printing belt slotting / die-cutting, printing belt slotting / die-cutting / gluing, and linked production lines. When working, the carton printing machine first makes a printing plate with the text and image to be printed, installs it on the printing machine, and then operates the printing machine to evenly apply ink to the areas with text and images on the printing plate, and then directly or indirectly transfers it to the corrugated cardboard or carton, thereby producing a printed replica identical to the printing plate.

The front push rod and the rear push rod are respectively arranged on a support plate through connecting members, and the front push rod and the rear push rod can respectively move away from or closer to the cardboard along the connecting members.

[0004] Existing cardboard alignment devices such as the above-mentioned ones mostly align the cardboards in the stack through corresponding components. After the cardboards are transferred to a designated area by a transfer vehicle, they are printed on by a printing press. In the specific implementation process, the cardboards need to be manually transferred after alignment, which makes the overall process more inconvenient.

The outer walls of the two groups of drive rods are respectively screwed together with two groups of screw sleeves, which are respectively fixedly connected to the tops of the two groups of vertical rods.

[0010] Preferably, two groups of transverse grooves are provided on the inner surface wall of the horizontal end of the top frame, and the two groups of vertical rods are slidingly connected to the horizontal end of the top frame through the two groups of transverse grooves respectively.

[0011] Preferably, a fixing bracket is fixedly installed on the rear end surface of the front rod, the fixing bracket is in an L-shaped structure, and a connecting spring is fixedly installed between the fixing bracket and the vertical rod.

[0012] Preferably, the positioning assembly includes an electromagnetic sheet fixedly mounted on the inner wall of the front opening, and a metal sheet matching the electromagnetic sheet is embedded on the rear end surface of the front rod.

[0013] Preferably, the alignment assembly includes two groups of horizontal alignment plates, which are respectively fixedly connected to the two groups of front rods. The front end surfaces of the two groups of horizontal alignment plates are slidably connected to the connecting frame, and the front end surface of the connecting frame is fixedly installed with a longitudinal alignment plate. The opposite surfaces of the two groups of horizontal alignment plates are slidably connected to the convex strips, and a pushing part for pushing the connecting frame is provided between the convex strips and the connecting frame.

[0014] Preferably, the pushing portion includes a pushing seat fixedly connected to the convex strip, and an elastic member is fixedly installed between the pushing seat and the horizontal plate, a matching seat is fixedly installed on one side of the connecting frame, the inclined surface of the matching seat is slidably matched with the inclined surface of the pushing seat, and a reset spring is fixedly installed between the matching seat and the horizontal plate.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0016] 1. In the present application, the printing assembly is directly integrated above the base, and the cardboard piece is placed on the top of the conveyor belt and between the two sets of horizontal alignment plates. Then the output end of the bidirectional motor drives the two sets of drive rods to rotate respectively. The two sets of drive rods drive the two sets of vertical rods respectively by screwing with the two sets of screw sleeves. The two sets of vertical rods drive the two sets of alignment rods to perform relative movement of a specified distance. The vertical rods are simultaneously linked to the horizontal alignment plates through connecting springs.

In this process, the convex strips are integrated into the interior of the horizontal alignment plates, and the convex strips are linked to the push seat. When the push seat compresses the elastic part, the inclined surface of the push seat cooperates with the inclined surface of the matching seat. When the push seat stretches the reset spring, the vertical rod is pulled through the connecting frame. The horizontal alignment plate moves longitudinally, and the longitudinal alignment plate pushes the cardboard to contact the baffle to complete the longitudinal alignment of the cardboard. Then the electromagnet is energized to attract the metal sheet. At this time, the two sets of horizontal alignment plates and the longitudinal alignment plate remain stationary, and the conveyor belt starts working, so that the single set of cardboard passes through the baffle periodically until the cardboard contacts the printing component, and the two sets of output ends of the bidirectional motor continue to rotate forward and backward periodically, and the vertical rod drives the alignment plate to swing back and forth and drives the connecting spring to expand and contract. The alignment plate aligns the horizontal position of the cardboard on the conveyor belt to avoid the cardboard from offsetting during the transfer process, thereby improving the alignment effect of the cardboard while ensuring the convenience of the cardboard alignment process.

[0017] 2. In the present application, the positioning rod can be rotated so that its open end is separated from the outer wall of the vertical end of the top frame. At this time, the sliding sleeve loses its restraint force, and the baffle can be moved vertically manually. The sliding sleeve moves synchronously along the outer wall of the vertical end of the top frame until the bottom of the baffle reaches a specified height from the top of the conveyor belt. Then, the positioning rod is rotated so that its open end is tightly attached to the outer wall of the top frame, and the sliding sleeve and the baffle are fixed again by friction. In addition, the setting of the front opening ensures that the position of the baffle will not hinder the subsequent movement of the front rod, so that the position of the baffle can be quickly adjusted according to the thickness of the cardboard.

[0028] The printing assembly is directly integrated on top of the base 1, and the cardboard piece is placed on the top of the conveyor belt 2 and between the two sets of horizontal alignment plates 14. Then the output end of the bidirectional motor 8 drives the two sets of drive rods 9 to rotate respectively. The two sets of drive rods 9 drive the two sets of vertical rods 10 respectively by screwing with the two sets of screw sleeves 20. The two sets of vertical rods 10 drive the two sets of alignment rods 3 to perform relative movement of a specified distance. The vertical rods 10 simultaneously link the front rod 13 and the horizontal alignment plate 14 through the connecting spring 21. The two sets of horizontal alignment plates 14 complete the horizontal alignment of the cardboard piece, and in this process, the convex strip 17 is combined with the inside of the horizontal alignment plate 14, and the convex strip 17 links the push seat 24. While the push seat 24 compresses the elastic part, the inclined surface of the push seat 24 cooperates with the inclined surface of the matching seat 23. While the matching seat 23 stretches the reset spring 25, through The connecting frame 15 pulls the longitudinal alignment plate 16 to move longitudinally, and the longitudinal alignment plate 16 pushes the cardboard piece to contact the baffle 5, thereby completing the longitudinal alignment of the cardboard. Then the electromagnetic sheet 12 is energized, which attracts the metal sheet 22. At this time, the two sets of horizontal alignment plates 14 and the longitudinal alignment plates 16 remain stationary, and the conveyor belt 2 starts working, so that a single set of cardboards periodically passes through the bottom of the baffle 5 until the cardboard piece contacts the printing assembly, and the two sets of output ends of the bidirectional motor 8 continue to rotate forward and backward periodically, and the vertical rod 10 drives the alignment rod 3 to swing back and forth and drives the connecting spring 21 to expand and contract. The alignment rod 3 aligns the cardboard pieces on the conveyor belt 2 in a horizontal position to avoid the cardboard from offsetting during the transfer process, thereby improving the alignment effect of the cardboard while ensuring the convenience of the cardboard alignment process.

The inner wall of the sliding sleeve 6 is screwed and connected with a positioning rod 7. The open end of the positioning rod 7 abuts against the outer wall of the vertical end of the top frame 4, and the positioning rod 7 can be rotated to make its open end disengage from the outer wall of the vertical end of the top frame 4. At this time, the sliding sleeve 6 loses its restraining force, and the baffle 5 can be moved vertically manually. The sliding sleeve 6 synchronously moves along the outer wall of the vertical end of the top frame 4 until the bottom of the baffle 5 reaches a specified height from the top of the conveyor belt 2. After that, the positioning rod 7 is rotated to make its open end close to the outer wall of the top frame 4, the sliding sleeve 6 and the baffle 5 are fixed again by friction. The setting of the front opening 11 ensures that the position of the baffle 5 will not hinder the subsequent movement of the front rod 13, and the position of the baffle 5 can be quickly adjusted according to the thickness of the cardboard.

[0030] Specifically, such as Figure 2 and Figure 3As shown, the driving assembly includes two groups of driving rods 9, which are respectively fixedly mounted on the two groups of output ends of the bidirectional motor 8. The outer walls of the two groups of driving rods 9 are respectively screwed together with two groups of screw sleeves 20, and the two groups of screw sleeves 20 are respectively fixedly connected to the tops of the two groups of vertical rods 10. The output ends of the bidirectional motor 8 respectively drive the two groups of driving rods 9 to rotate, and the two groups of driving rods 9 respectively drive the two groups of vertical rods 10 by screwing with the two groups of screw sleeves 20. The two groups of vertical rods 10 drive the two groups of alignment rods 3 to perform relative movement of a specified distance. Two groups of transverse grooves 19 are provided on the inner wall of the horizontal end of the top frame 4. The two groups of vertical rods 10 are respectively slidably connected to the horizontal end of the top frame 4 through the two groups of transverse grooves 19, so as to limit the axial deflection of the two groups of vertical rods 10.

[0031] Specifically, such as Figure 1 and Figure 2 As shown, a fixing frame 18 is fixedly installed on the rear end face of the front rod 13, and the fixing frame 18 is an L-shaped structure. A connecting spring 21 is fixedly installed between the fixing frame 18 and the vertical rod 10, so as to realize the connection between the front rod 13 and the vertical rod 10. At the same time, after the front rod 13 is subsequently fixed, the vertical rod 10 can still move independently. The positioning component includes an electromagnetic sheet 12 fixedly installed on the inner wall of the front opening 11. The electromagnetic sheet 12 adopts the SH-H1004843 square electromagnet, and a metal sheet 22 matching the electromagnetic sheet 12 is embedded in the rear end face of the front rod 13.

[0032] Specifically, such as Figure 1 and Figure 2 As shown, the alignment assembly includes two groups of horizontal alignment plates 14, the two groups of horizontal alignment plates 14 are fixedly connected to the two groups of front rods 13 respectively, the front end surfaces of the two groups of horizontal alignment plates 14 are slidably connected to the connecting frame 15, the front end surface of the connecting frame 15 is fixedly installed with a longitudinal alignment plate 16, the opposite surfaces of the two groups of horizontal alignment plates 14 are slidably connected to the convex strips 17, and a pushing portion for pushing the connecting frame 15 is provided between the convex strips 17 and the connecting frame 15, the pushing portion includes a pushing seat 24 fixedly connected to the convex strips 17, and an elastic member is fixedly installed between the pushing seat 24 and the horizontal alignment plate 14, a matching seat 23 is fixedly installed on one side of the connecting frame 15, and the inclined surface of the matching seat 23 is inclined with the pushing seat 24 The surfaces are slidably matched, and a return spring 25 is fixedly installed between the matching seat 23 and the horizontal alignment plate 14. The vertical rod 10 links the front rod 13 and the horizontal alignment plate 14 through the connecting spring 21. The two sets of horizontal alignment plates 14 complete the horizontal alignment of the cardboard pieces, and in this process, the convex strip 17 is integrated into the interior of the horizontal alignment plate 14, and the convex strip 17 links the push seat 24. While the push seat 24 compresses the elastic part, the inclined surface of the push seat 24 cooperates with the inclined surface of the matching seat 23. While the matching seat 23 stretches the return spring 25, the longitudinal alignment plate 16 is pulled by the connecting frame 15 for longitudinal movement. The longitudinal alignment plate 16 pushes the cardboard piece to contact the baffle 5, thereby completing the longitudinal alignment of the cardboard.

[0033] Working principle: The printing component is directly integrated on the top of the base 1. The cardboard piece is placed on the top of the conveyor belt 2 and between the two sets of horizontal alignment plates 14. Then the output end of the bidirectional motor 8 drives the two sets of drive rods 9 to rotate respectively. The two sets of drive rods 9 drive the two sets of vertical rods 10 respectively by screwing with the two sets of screw sleeves 20. The two sets of vertical rods 10 drive the two sets of alignment rods 3 to move relative to each other at a specified distance. The vertical rods 10 simultaneously link the front rod 13 and the horizontal alignment plate 14 through the connecting spring 21. The two sets of horizontal alignment plates 14 complete the horizontal alignment of the cardboard piece, and at this During the process, the convex strip 17 is combined with the inside of the horizontal alignment plate 14, and the convex strip 17 is linked to the push seat 24. When the push seat 24 compresses the elastic member, the inclined surface of the push seat 24 cooperates with the inclined surface of the matching seat 23. When the matching seat 23 stretches the reset spring 25, the longitudinal alignment plate 16 is pulled by the connecting frame 15 to move longitudinally. The longitudinal alignment plate 16 pushes the cardboard part to contact the baffle 5, thereby completing the longitudinal alignment of the cardboard. Then the electromagnetic sheet 12 is energized, which attracts the metal sheet 22. At this time, the two sets of horizontal alignment plates 14 and longitudinal alignment plates 16 remain in the same position. The conveyor belt 2 starts working, so that a single set of cardboards passes through the bottom of the baffle 5 periodically until the cardboard pieces touch the printing assembly, and the two sets of output ends of the bidirectional motor 8 continue to rotate forward and backward periodically, and the vertical rod 10 drives the alignment rod 3 to swing back and forth and drives the connecting spring 21 to expand and contract. The alignment rod 3 aligns the cardboard pieces on the conveyor belt 2 in a horizontal position to prevent the cardboards from offsetting during the transfer process, thereby improving the alignment effect of the cardboards while ensuring the convenience of the cardboard alignment process. The positioning rod 7 can be rotated to make its open end When the upper frame 4 is separated from the outer wall of the vertical end of the top frame 4, the sliding sleeve 6 loses its restraint force, and the baffle 5 can be moved vertically manually. The sliding sleeve 6 moves synchronously along the outer wall of the vertical end of the top frame 4 until the bottom of the baffle 5 reaches a specified height from the top of the conveyor belt 2. The positioning rod 7 is rotated to make its open end close to the outer wall of the top frame 4, and the sliding sleeve 6 and the baffle 5 are fixed again by friction. The setting of the front opening 11 ensures that the position of the baffle 5 will not hinder the subsequent movement of the front rod 13, and the position of the baffle 5 can be quickly adjusted according to the thickness of the cardboard.
