Description

Technical Field

[0001] This invention relates to the field of product packaging technology, and in particular to a steering mechanism for packaging machines. Background Technology

[0002] In the packaging industry, the length and width of packaged products often vary. Therefore, sometimes the packaging materials need to be rotated 90 degrees for output or rotated 90 degrees for secondary packaging according to the production line design. In this case, a mechanism with a 90-degree turning function is required.

[0003] Current 90-degree steering mechanisms include blocking steering, 90-degree docking curve conveying, cross lifting and rotating mechanisms, and other steering mechanisms. Blocking steering mechanisms have a simple structure but low operating speed, poor stability, and poor speed controllability; 90-degree docking curve conveying occupies a large layout space; and cross lifting and rotating mechanisms have low operating speed and certain limitations in application. Summary of the Invention

[0004] The purpose of this invention is to provide a steering mechanism for a packaging machine, which has the advantage that the clamping block rotates 90° and drives the material to rotate, making it convenient and quick to rotate the material 90 degrees.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: including a steering transmission mechanism and a steering chain assembly connected to the steering transmission mechanism, wherein the steering chain assembly includes two chains and a plurality of steering clamping block assemblies equally spaced between the two chains;

[0006] The steering block assembly includes a clamping block with a groove. A T-shaped block is inserted into the groove. A steering component is fixedly connected to the T-shaped block. A second bearing seat is provided on the steering component. Fixed blocks are movably connected to the bearings at both ends of the second bearing seat. A swing arm is provided on the fixed block. A first roller is rotatably connected to the second bearing seat. The first roller is connected to the steering component via the swing arm. Second rollers are rotatably connected to the second bearing on both sides near the first roller. An upper steering guide rail and a lower steering guide rail are provided in the steering transmission mechanism for the first roller to roll.

[0007] Through the above technical solution, the motor drives the chain of the steering transmission mechanism to rotate, and the chain drives the steering clamping block assembly to move. The first roller moves in the lower steering guide rail. As the first roller moves, it drives the steering component to rotate through the swing arm. The clamping block installed on the steering component also rotates. The clamping block rotates 90° from one end of the steering mechanism to the other end. When the steering component continues to move to the upper part of the mechanism, the first roller moves in the upper steering guide rail. When the steering component moves to the other end, the steering clamping block rotates 90° again. The steering mechanism and the conveying mechanism keep in sync. When the material is conveyed to the clamping block of the steering clamping block assembly, the clamping block drives the material to rotate 90 degrees in succession according to a certain rhythm.

[0008] The invention is further configured such that the clamping block is connected to the T-block via a positioning pin.

[0009] The present invention is further configured such that: the upper steering guide rail and the lower steering guide rail are respectively disposed on the steering transmission mechanism, and the upper steering guide rail and the lower steering guide rail are respectively provided with guide grooves in the form of a "sine curve".

[0010] The present invention is further configured such that: the steering transmission mechanism includes two side plates, the outer sides of the two side plates are connected to the packaging machine via a hanger, a mounting plate is connected to the outer side of one of the side plates, a servo motor is mounted on the outer side of the mounting plate, an output shaft is coaxially connected to the output end of the servo motor via a coupling, a drive sprocket is connected to the end of the output shaft, and a driven sprocket is connected to the drive sprocket via a chain.

[0011] The present invention is further configured such that a first bearing seat connected to the output shaft is connected to the side plate.

[0012] The present invention is further configured such that an upper guide rail, a middle guide rail and a lower guide rail are provided on one side opposite to the two side plates, the upper guide rail, the middle guide rail and the lower guide rail are connected to each other end to end, and the second roller rolls within the upper guide rail, the middle guide rail and the lower guide rail.

[0013] The invention is further configured such that: the fixing blocks at both ends of the second bearing seat are respectively fixed on two chains, the shaft segments of the two fixing blocks are installed in the bearings at the ends of the second bearing seat, and the second bearing seat has a degree of freedom of rotation about the shaft segments of the fixing blocks.

[0014] The invention is further configured such that: chain guide grooves are provided on both side plates, and two chains are respectively laid in the two chain guide grooves. The chain guide grooves on the side plates are equidistant from the guide grooves formed by the end-to-end connection of the upper guide rail, the middle guide rail and the lower guide rail. Under the combined action of these two guide grooves, the clamping block will continue to be horizontally and vertically raised or lowered a certain distance at the inclined upward and inclined downward positions at both ends of the mechanism to safely approach or leave the packaged product.

[0015] In summary:

[0016] 1. The present invention relates to a steering mechanism for a packaging machine, wherein several steering unit components are arranged on the chain, which can continuously rotate the material 90 degrees at a certain rhythm under the drive of a servo motor, and the speed is controllable.

[0017] 2. The present invention provides a steering mechanism for a packaging machine, wherein a clamping block is installed on the steering clamping block unit assembly, and the clamping block is positioned by a positioning pin, which enables quick replacement.

[0018] 3. The purpose of this invention is to provide a steering mechanism for a packaging machine, wherein the steering unit assembly has a degree of rotational freedom about a fixed block.

[0019] 4. The present invention provides a steering mechanism for a packaging machine, wherein the clamping block maintains a horizontal lifting distance at one end during the downward and upward tilting movements at both ends of the mechanism, thereby avoiding the risk of the clamping block pressing or pushing the package during the descent or ascent.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] Example: Refer to as follows Figure 1-4As shown, a steering mechanism for a packaging machine includes a steering transmission mechanism and a steering chain assembly connected to the steering transmission mechanism. The steering chain assembly includes two chains 18 and a plurality of steering clamping block assemblies 19 disposed between the two chains 18. The steering clamping block 19 assembly includes clamping blocks 19, with T-slots on the clamping blocks 19. T-blocks 20 are inserted into the T-slots and fixedly connected to a steering component 21. The shaft segment on the steering component 21 is installed in a second bearing seat 24. Fixed blocks 22 are respectively installed at both ends of the second bearing seat 24. A swing arm 27 is provided on the fixed block 22. The swing arm 27 is connected to the shaft end of the steering component 21 and a first roller 25 is provided on it. Second rollers 26 are respectively provided on both sides of the second bearing 24. An upper steering guide rail 29 and a lower steering guide rail 30 are provided in the steering transmission mechanism for the first rollers 25 to roll. The upper steering guide rail 29 and the lower steering guide rail 30 are respectively disposed on the middle connecting plate of the steering transmission mechanism.

[0027] Specifically, the motor on the steering transmission mechanism drives the chain 18 to rotate, which in turn drives the steering clamp 19 assembly to move. The first roller 25 slides within the lower steering guide rail 30. As the position of the first roller 25 changes during its movement, it drives the swing arm 27 to rotate. The swing arm 27 drives the steering component 21 to rotate. The steering component 21 rotates around the bearing seat, which in turn drives the clamp 19 to rotate. The clamp 19 rotates 90°, and the clamp 19 drives the material to rotate, allowing the material to rotate 90 degrees conveniently and quickly.

[0028] Furthermore, the clamping block 19 is installed on the T-block 20 through the T-slot, and the positioning pin 28 positions the clamping block 19, enabling quick replacement and facilitating the replacement of different clamping blocks 19 for products with different packaging sizes.

[0029] Furthermore, an upper guide rail 31, a middle guide rail 32, and a lower guide rail 33 are provided on the opposite side of the two side plates 11. The upper guide rail 31, the middle guide rail 32, and the lower guide rail 33 are connected end to end, and the second roller 26 rolls within the upper guide rail 31, the middle guide rail 32, and the lower guide rail 33. Under the combined action of the guide rail and the guide groove of the chain 18, the clamping block 19 maintains a horizontal lifting distance at one end during the downward and upward tilting movements at both ends of the mechanism. This solves the risk of the clamping block 19 pushing or pressing the bag during the descent or ascent when the guide groove of the chain 18 acts alone.

[0030] Furthermore, the steering transmission mechanism includes several side plates 11. The outer sides of two side plates 11 are connected to the packaging machine via hangers 17. A mounting plate 12 is connected to the outer side of one side plate 11, and a servo motor 13 is mounted on the outer side of the mounting plate 12. The output end of the servo motor 13 is connected to the output shaft via a coupling. A drive sprocket 15 is mounted on the output shaft. The drive sprocket 15 is connected to a driven sprocket 16 via a chain 18. A first bearing seat 14 connected to the output shaft is connected to the side plate 11. The servo motor 13 drives the output shaft to rotate, which in turn drives the drive sprocket 15 to rotate. The drive sprocket 15 then drives the chain 18 to rotate, fixing the fixing blocks 22 on both sides of the second bearing seat onto the two chains 18. Thus, the chains 18 can easily and quickly move the steering clamp block 19 assembly between the two side plates 11.

[0031] Operating steps: The servo motor 13 drives the output shaft to rotate, the output shaft drives the drive sprocket 15 to rotate, and the drive sprocket 15 drives the chain 18 to rotate. The fixing blocks 22 on both sides of the second bearing seat are fixed to the two chains 18 respectively. Then, the chain 18 can easily and quickly drive the steering clamping block 19 assembly to move between the two side plates 11. The first roller 25 slides in the lower steering guide rail 30. At this time, the first roller 25 drives the swing arm 27 to rotate, and the swing arm 27 drives the steering component 21 and the clamping block 19 on it to rotate. From the driven end to the driving end, the clamping block 19... Rotating 90° causes clamping block 19 to rotate, allowing the material to rotate 90 degrees easily and quickly. Positioning pin 28 positions clamping block 19, enabling quick replacement. This allows for the replacement of different clamping blocks 19 for products of different packaging sizes. Under the combined action of the guide rail and the guide groove of chain 18, clamping block 19 maintains a horizontal lifting distance at one end during tilting downwards and tilting upwards at both ends of the mechanism. This solves the risk of clamping block 19 pushing or pressing the bag during descent or ascent when the guide groove of chain 18 acts alone.

[0032] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
