Description

Technical Field

[0001] This utility model relates to paper box forming equipment, specifically to a paper box forming machine with a rigid handle. Background Technology

[0002] A cardboard box forming machine is a piece of equipment used for the automated production of cardboard boxes. After the cardboard boxes are produced, handles need to be attached to them according to different usage requirements. Traditionally, handles are made of paper or non-woven fabric and are attached to the cardboard boxes by gluing or welding. However, in some usage scenarios, rigid handles, such as handles made of iron wire or alloy wire, need to be attached to the cardboard boxes. Traditionally, the handles are manually inserted and connected, which is labor-intensive for workers and results in low overall production efficiency, making it impossible to achieve automated, high-speed, and high-quality production. Utility Model Content

[0003] In view of the deficiencies in the prior art, the technical problem to be solved by this utility model is to provide a paper box forming machine with a rigid handle for solving the above-mentioned problems.

[0004] Therefore, this utility model is implemented using the following solution:

[0005] A cardboard box forming machine with a rigid handle includes a box forming mechanism. The machine is characterized by: baffles positioned on the left and right sides of the discharge end of the box forming mechanism; a support plate fixedly positioned above the baffles; movable trays positioned on the left and right sides of the support plate; and a wire traction roller assembly that pulls the wire above the support plate and movable trays. A liftable first bending block is positioned corresponding to the movable tray. After the first bending block and the movable tray complete the bending of the wire end, the movable tray moves and separates from the wire. Liftable second bending blocks are positioned on both sides of the support plate. A movable wire pressing block is positioned on the outer side of the baffle. The wire pressing block and the baffle cooperate to insert the first bent portions at both ends of the wire into the formed box body.

[0006] A cutting blade is provided corresponding to the first bending pressure block near the metal wire traction roller group.

[0007] The first bending pressure block is disposed on the first lifting seat, and an elastic reset member is disposed corresponding to the first lifting seat. A first cam is pressed tightly on the top of the first lifting seat. The second bending pressure block is disposed on the second lifting seat, and an elastic reset member is disposed corresponding to the second lifting seat. A second cam is pressed tightly on the top of the second lifting seat. The first and second cams are connected to the drive shaft, and the drive shaft is connected to the first motor.

[0008] The movable pallet is set in the guide groove on the guide plate, and a spring is tightly pressed between the movable pallet and the guide groove. The movable pallet has a protrusion with an inclined surface. The first lifting seat is provided with a pressing block, which can press the inclined surface on the protrusion, thereby driving the movable pallet to move in the guide groove and separate from the metal wire.

[0009] The pressing block is mounted on a movable seat, which is hinged to one end of the first transmission arm. The other end of the first transmission arm is eccentrically hinged to the rotating disk. The rotating disk is connected to the second motor for transmission. A guide assembly is provided corresponding to the movable seat.

[0010] The aforementioned technical solution provides a paper box forming machine with a rigid handle, which can automatically pull, cut, bend, and connect the metal wire to the paper box, thereby realizing the connection of the rigid handle on the paper box. The entire process is automated, replacing traditional manual operation, effectively improving the forming quality and efficiency, and greatly reducing the labor intensity of workers.

[0017] As shown in the figure, the present invention discloses a paper box forming machine with a rigid handle, including a box forming mechanism. The box forming mechanism includes a stacking rack 1 on which paper box boards 2 are stacked. A suction cup assembly is provided on the stacking rack 1 to attract a single paper box board 2 and make it fall into the forming mold. Then, the forming rod is controlled to push the paper box board 2 through the forming mold to realize the forming and delivery of the paper box. This is a common structure on the market and belongs to the prior art, so its specific structure will not be described in detail. Baffles 7 are provided on the left and right sides of the discharge end of the box forming mechanism. A support plate 17 is fixedly provided above the baffles 7. Movable trays 19 are provided on the left and right sides of the support plate 17. The mechanism also includes a wire traction roller group 3, which can pull the wire to the top of the support plate 17 and the movable tray 19. A first bending pressure block 23 that can be raised and lowered is provided on the movable tray 19. After the first bending pressure block 23 cooperates with the movable tray 19 to complete the bending of the end of the wire, the movable tray 19 moves and separates from the wire. A second bending pressure block 18 that can be raised and lowered is provided on both sides of the support plate 17. A movable wire pressing block 6 is provided on the outside of the baffles 7. The wire pressing block 6 cooperates with the baffles to insert the first bent part 15 at both ends of the wire into the formed box.

[0018] Furthermore, a cutting blade 24 is provided corresponding to the first bending pressure block 23 near the wire traction roller group 3. With the above structure, the first bending pressure block 23 can directly cooperate with the cutting blade 24 to cut the wire during the descent process.

[0019] Furthermore, the first bending pressure block 23 is disposed on the first lifting seat 9, and a corresponding elastic reset component is disposed on the first lifting seat 9. The top of the first lifting seat 9 is tightly pressed with the first cam 10. The second bending pressure block 18 is disposed on the second lifting seat 13, and a corresponding elastic reset component is disposed on the second lifting seat 13. The top of the second lifting seat 13 is tightly pressed with the second cam 11. The first and second cams are connected to the drive shaft 8, and the drive shaft 8 is connected to the first motor. Using the above technical solution, by controlling the rotation of the drive shaft 8 to drive the first and second cams to rotate, the first and second lifting seats can be squeezed down, thereby driving the first and second bending pressure blocks down to achieve the compression and bending of the metal wire. The elastic reset component is used to achieve the upward reset of the first and second lifting seats. Of course, in addition to the above structure, cylinders, hydraulic cylinders, and other structures can also be used to drive the lifting action of the lifting seats.

[0020] Furthermore, the movable support plate 19 is disposed within the guide groove 25 on the guide plate 14, and a spring is tightly pressed between the movable support plate 19 and the guide groove 25. The movable support plate 19 has a protrusion 20 with an inclined surface 21. A pressing block 22 is disposed on the first lifting seat 9. The pressing block 22 can press the inclined surface 21 on the protrusion 20, causing the movable support plate 19 to move within the guide groove 25 and separate from the metal wire. With the above structure, during the descent of the first lifting seat 9, the pressing block 22 can press against the protrusion 20, causing the movable support plate 19 to separate from the metal wire and make room, thereby ensuring that the metal wire can smoothly undergo the second bending operation.

[0021] Furthermore, the pressing block 6 is mounted on the movable seat 5, which is hinged to one end of the first transmission arm 26. The other end of the first transmission arm 26 is eccentrically hinged to the rotating disk 4, which is connected to the second motor. A guide assembly is provided corresponding to the movable seat 5, which can be a slide rail or slide block structure. With the above structure, by controlling the rotation of the rotating disk 4 and transmitting it through the first transmission arm 26, the movable seat 5 and the pressing block 6 can be moved.

[0022] The working principle of this utility model is as follows: The box forming mechanism pushes the formed cardboard box to the baffle 7, so that the baffle 7 blocks the inner wall of the cardboard box. At this time, the wire traction roller group 3 has already pulled the wire to the top of the movable tray 19 and the support plate 17. Then, the first lifting seat 9 is controlled to drive the first bending pressure block 23 to descend. One of the first bending pressure blocks 23 cooperates with the cutting blade block 24 to cut the wire, and the first bending pressure block 23 cooperates with the movable tray 19 to form the first bending part 15 of the wire. Then, As the first lifting seat 9 continues to descend, the squeezing block 22 and the protrusion 20 squeeze and drive the movable pallet 19 to move within the guide groove 25 and separate from the metal wire. Then, the second lifting seat 13 is controlled to descend, driving the two second bending blocks 18 to descend and cooperate with the support plate 17 to form the second bending part 16 on the metal wire, so that the metal wire is formed into a handle shape. Then, the wire pressing block 6 is controlled to move and squeeze the metal wire and cooperate with the baffle 7 to press the first bending part 15 of the metal wire into the side wall of the cardboard box, thus connecting the rigid metal wire handle to the cardboard box.
