Description

Technical Field

[0001] This utility model relates to the field of sealing and cutting packaging machines, and in particular to a vertical L-shaped sealing and cutting guide rod linkage mechanism. Background Technology

[0002] The vertical L-shaped sealing and cutting machine is a multi-functional packaging equipment, named for its unique "L"-shaped structure design. This design makes the machine more compact in terms of space and convenient for layout on the production line. Vertical L-shaped sealing and cutting machines are usually made of high-strength materials, which improves their stability and durability.

[0003] The existing vertical L-shaped sealing guide rod linkage mechanism typically uses a single electric push rod and multiple limit rods for height adjustment, which results in poor linkage and synchronization, leading to inaccurate adjustment.

[0004] Therefore, to address the issue that the existing vertical L-shaped sealing and cutting guide rod linkage mechanism typically uses a single electric push rod and multiple limit rods for height adjustment, resulting in poor linkage and synchronization and inaccurate adjustment, a new vertical L-shaped sealing and cutting guide rod linkage mechanism can be designed. This mechanism incorporates a rotating disk. Rotating the disk drives the connected screw to rotate, which in turn drives the drive gear at the bottom of the corresponding screw to rotate. This drive gear, in conjunction with a chain, drives the remaining drive gears to rotate synchronously, thereby driving the remaining two screws to rotate synchronously. This allows for height adjustment of the L-shaped base plate, improving the synchronization of position adjustment. Utility Model Content

[0005] To overcome the problem that the existing vertical L-shaped sealing guide rod linkage mechanism usually uses a single electric push rod and multiple limit rods for height position adjustment, which has poor linkage and synchronization, resulting in inaccurate adjustment.

[0006] The technical solution of this utility model is as follows: a vertical L-shaped sealing and cutting guide rod linkage mechanism, including an L-shaped base plate; it also includes a threaded seat, a screw, a base plate, a rotating disk, a drive gear, and a chain. Threaded seats are embedded and installed at the three corners of the upper surface of the L-shaped base plate. The screw is rotatably connected through the inner surface of the threaded seat. The base plate is provided on the bottom surface of the screw. The bottom of the base plate is connected to the sealing and cutting machine table. A rotating disk is provided at the lower position of the outer surface of the screw on the left front side. Drive gears are provided on the outer surfaces of the three screws at the upper position of the base plate. A chain is sleeved on the outer surface of the three drive gears.

[0007] Preferably, by setting a rotating disk, rotating the disk can drive the screw connected to it to rotate, thereby driving the drive gear at the bottom of the corresponding screw to rotate. When the drive gear rotates, it can cooperate with the chain to drive the other drive gears to rotate synchronously, thereby driving the remaining two screws to rotate synchronously. This allows the height of the L-shaped base plate to be adjusted, improving the synchronicity of position adjustment. This solves the problem that the existing vertical L-shaped sealing guide rod linkage mechanism usually uses a single electric push rod and multiple limit rods for height position adjustment, which has poor linkage and synchronicity, resulting in inaccurate adjustment.

[0008] Preferably, a mounting plate is provided between the two front chassis. The bottom surface of the mounting plate is connected to the sealing and cutting machine table. An auxiliary gear is provided at the rear position of the upper surface of the mounting plate. The auxiliary gear meshes with the chain. A tension plate is rotatably connected to the upper surface of the auxiliary gear. The side surface of the tension plate is in contact with the side of the chain.

[0009] Preferably, sleeves are provided at the corners of the upper surface of the L-shaped base plate, and positioning rods are provided through the inner surface of the sleeves. The bottom surface of the positioning rods is connected to the sealing and cutting machine table. Hot cutting modules are connected to the top surfaces of the two positioning rods on the left side, and the hot cutting modules are slidably connected to the positioning rods on the right side.

[0010] Preferably, a support plate is slidably connected through the outer surfaces of the three positioning rods, a gasket is provided on the upper surface of the support plate, a damper is provided on the upper surface of the gasket, a spring is sleeved on the outer surface of the damper, and a liner is provided on the upper surface of the damper.

[0011] Preferably, a symmetrical first hinge seat is provided on the rear position of the upper surface of the L-shaped base plate, and a cylinder is rotatably connected between the two first hinge seats. A rotating seat is provided at the extension end of the cylinder. A symmetrical second hinge seat is provided on the front side of the upper surface of the L-shaped base plate, and a rotating shaft is rotatably connected between the two second hinge seats. A first connecting rod is sleeved on the outer surface of the rotating shaft. The first connecting rod is rotatably connected to the rotating seat. A first connecting plate is provided at both the front and rear ends of the rotating shaft. One end of a first connecting rod is rotatably connected to the side surface of the first connecting plate away from the L-shaped base plate. The other end of the first connecting rod is rotatably connected to the support plate.

[0012] Preferably, a second connecting rod is provided on the outer surface of the rotating shaft at the left side of the first connecting rod. One end of a linkage rod is rotatably connected to the side of the second connecting rod. Symmetrical third hinge seats are provided on the rear side of the upper surface of the L-shaped base plate. A third connecting rod is rotatably connected between the two third hinge seats. The other end of the linkage rod is rotatably connected to the third connecting rod. A second connecting plate is rotatably connected to the front end of the third connecting rod. One end of a second connecting rod is rotatably connected to the left side of the second connecting plate. The other end of the second connecting rod is rotatably connected to the support plate.

[0013] Preferably, one end of the third link is rotatably connected to the left side of the second connecting plate away from the second link, and the other end of the third link is rotatably connected to the heat-cutting module.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting a rotating disk, rotating the disk can drive the screw connected to it to rotate, thereby driving the drive gear at the bottom of the corresponding screw to rotate. When the drive gear rotates, it can cooperate with the chain to drive the other drive gears to rotate synchronously, thereby driving the remaining two screws to rotate synchronously. This allows for the adjustment of the height of the L-shaped base plate, improving the synchronicity of position adjustment. This solves the problem that the existing vertical L-shaped sealing guide rod linkage mechanism usually uses a single electric push rod and multiple limit rods for height position adjustment, which has poor linkage and synchronicity, resulting in inaccurate adjustment.

[0022] Please see Figures 1-4 This utility model provides an embodiment: a vertical L-shaped sealing and cutting guide rod linkage mechanism, including an L-shaped base plate 1; it also includes a threaded seat 2, a screw 3, a base plate 4, a rotating disk 5, a drive gear 6, and a chain 7. Threaded seats 2 are embedded and installed at three corners of the upper surface of the L-shaped base plate 1. The screw 3 is rotatably connected through the inner surface of the threaded seat 2. The base plate 4 is provided on the bottom surface of the screw 3, and the bottom of the base plate 4 is connected to the sealing and cutting machine table.

Drive gears 6 are provided on the upper side of the outer surface of the chassis 4. Chains 7 are fitted on the outer surfaces of the three drive gears 6. By setting a rotating disk 5, the screw 3 connected to it can be rotated when the rotating disk 5 is rotated, thereby driving the drive gear 6 at the bottom of the corresponding screw 3 to rotate. When the drive gear 6 rotates, it can cooperate with the chain 7 to drive the other drive gears 6 to rotate synchronously, thereby driving the remaining two screws 3 to rotate synchronously. This allows the height of the L-shaped base plate 1 to be adjusted, improving the synchronization of position adjustment.

[0023] Please see Figures 1-4 In this embodiment, a mounting plate 8 is provided between the two front chassis 4. The bottom surface of the mounting plate 8 is connected to the sealing and cutting machine table. An auxiliary gear 9 is provided at the rear position of the upper surface of the mounting plate 8. The auxiliary gear 9 meshes with the chain 7. A tension disc 10 is rotatably connected to the upper surface of the auxiliary gear 9.

Sleeves 11 are provided at the corners of the upper surface of the L-shaped base plate 1. A positioning rod 12 is provided through the inner surface of the sleeve 11. The bottom surface of the positioning rod 12 is connected to the sealing and cutting machine table. The top surfaces of the two positioning rods 12 on the left are connected to the hot cutting module 13. The hot cutting module 13 is slidably connected to the right positioning rod 12. By setting the positioning rods 12, the lifting and lowering of the hot cutting module 13 can be limited, improving stability. The outer surfaces of the three positioning rods 12 are slidably connected to the support plate 14. The upper surface of the support plate 14 is provided with a gasket 15. The upper surface of the gasket 15 is provided with a damper 16. The outer surface of the damper 16 is fitted with a spring 17. The upper surface of the damper 16 is provided with a liner 18.

[0024] Please see Figures 1-4In this embodiment, symmetrical first hinge seats 19 are provided on the rearward position of the upper surface of the L-shaped base plate 1. A cylinder 20 is rotatably connected between the two first hinge seats 19. A rotating seat 21 is provided at the telescopic end of the cylinder 20. Symmetrical second hinge seats 22 are provided on the front side of the upper surface of the L-shaped base plate 1. A rotating shaft 23 is rotatably connected between the two second hinge seats 22. A first connecting rod 24 is sleeved on the outer surface of the rotating shaft 23. The first connecting rod 24 is rotatably connected to the rotating seat 21.

One end of a first connecting rod 26 is rotatably connected to one side surface of the L-shaped base plate 1, and the other end of the first connecting rod 26 is rotatably connected to the support plate 14. A cylinder 20 is provided so that, during operation, its telescopic end can push the rotating seat 21 and the first connecting rod 26, thereby causing the rotating shaft 23 to rotate. When the rotating shaft 23 rotates, it drives the first connecting plate 25 to rotate, which in turn drives the first connecting rod 26 to rotate, thus lifting the support plate 14. A second connecting rod 27 is provided on the outer surface of the rotating shaft 23, located to the left of the first connecting rod 24. The side of the second connecting rod 27 rotates... One end of the linkage rod 28 is rotatably connected to the upper surface of the L-shaped base plate 1, and symmetrical third hinge seats 29 are provided on the rear side of the upper surface. A third connecting rod 30 is rotatably connected between the two third hinge seats 29. The other end of the linkage rod 28 is rotatably connected to the third connecting rod 30. The front end of the third connecting rod 30 is rotatably connected to a second connecting plate 31. One end of a second connecting rod 32 is rotatably connected to the left side surface of the second connecting plate 31. The other end of the second connecting rod 32 is rotatably connected to the support plate 14. By setting the linkage rod 28, the second connecting rod 27 can be driven to move when the rotating shaft 23 rotates. The third connecting rod 30 is rotated via the linkage rod 28, which in turn drives the second connecting plate 31 and the second connecting rod 32 to rotate, thereby assisting in the lifting and lowering of the pallet 14 and making it more stable. The left side of the second connecting plate 31, away from the second connecting rod 32, is rotatably connected to one end of the third connecting rod 33. The other end of the third connecting rod 33 is rotatably connected to the hot-cutting module 13. By setting the third connecting rod 33, when the third connecting rod 30 rotates, it can drive the third connecting rod 33 to rotate, thereby driving the hot-cutting module 13 to lift and lower.

[0025] During operation, the auxiliary gear 9 is installed, and the rotation of the chain 7 drives the auxiliary gear 9 to rotate, thereby driving the tension plate 10 to rotate synchronously. The tension plate 10 can provide a certain pressure on the side of the chain 7 to prevent the chain 7 from slack, thus improving transmission efficiency. The positioning rod 12 can limit the lifting and lowering of the hot cutting module 13, improving stability. The spring 17 and damper 16 can provide a buffering effect, making the contact between the liner 18 and the hot cutting module 13 elastic, improving the service life of the device. The cylinder 20 can push the rotating seat 21 and the first connecting rod 26 at its telescopic end during operation, thereby making the rotation... The shaft 23 rotates, which drives the first connecting plate 25 to rotate, thereby driving the first connecting rod 26 to rotate, thus lifting the pallet 14. By setting the linkage rod 28, the shaft 23 can rotate, which drives the second connecting rod 27 to rotate, which in turn drives the third connecting rod 30 to rotate. The third connecting rod 30 drives the second connecting plate 31 and the second connecting rod 32 to rotate, thereby assisting in the lifting and lowering of the pallet 14 and making it more stable. By setting the third connecting rod 33, the third connecting rod 30 can rotate, thereby driving the hot-cutting module 13 to lift and lower.

[0026] Through the above steps, by setting a rotating disk 5, rotating the rotating disk 5 can drive the screw 3 connected to it to rotate, thereby driving the drive gear 6 at the bottom of the corresponding screw 3 to rotate. When the drive gear 6 rotates, it can cooperate with the chain 7 to drive the other drive gears 6 to rotate synchronously, thereby driving the remaining two screws 3 to rotate synchronously. This allows the height of the L-shaped base plate 1 to be adjusted, improving the synchronicity of position adjustment. This solves the problem that the existing vertical L-shaped sealing guide rod linkage mechanism usually uses a single electric push rod and multiple limit rods for height position adjustment, which has poor linkage and synchronicity, resulting in inaccurate adjustment.
