Description

Technical Field

[0001] This invention belongs to the field of packaging production line technology, and in particular relates to a novel pallet blocking mechanism. Background Technology

[0002] On a packaging conveyor production line, the pallet blocking mechanism is a key device used to precisely control the dwell position and movement of pallets on the conveyor line.

[0003] Currently, traditional pallet blocking mechanisms use a lifting cylinder to push a blocking plate, which is then guided upwards by guide grooves at both ends to block the pallet. However, this design has a significant drawback: when the blocking plate retracts, it rubs against the pallet, which can easily cause deformation or even jamming, preventing proper retraction and reducing the stability and safety of the equipment, thus severely impacting the overall performance of the machine.

[0004] In summary, the existing pallet blocking mechanism suffers from low operational stability and safety, which affects the overall performance of the machine. Summary of the Invention

[0005] This invention provides a novel pallet blocking mechanism that can solve the problems of low operational stability and safety, and the impact on the overall performance of existing pallet blocking mechanisms.

[0006] To achieve the above objectives, a novel pallet blocking mechanism is proposed according to an embodiment of the first aspect of the present invention, comprising a frame; A conveying assembly, located within the frame, is used for conveying pallets; The conveying assembly includes a plurality of conveying rollers rotatably disposed within the frame port; Also includes: Adjustable blocking mechanism for positioning the pallet; The adjusting blocking mechanism includes a mounting base 1 and a mounting base 2 symmetrically fixedly connected to the frame, an adjusting cylinder fixedly installed on the mounting base 1 and the mounting base 2, a swing arm 1 rotatably installed on the mounting base 1 via a rotating shaft, a swing arm 2 rotatably installed on the mounting base 2 via a rotating shaft, a baffle plate fixedly installed on the inner side of the front end of the swing arm 1 and the swing arm 2, and a connector fixedly installed at the end of the swing arm 1 and the swing arm 2. The rod ends of the two regulating cylinders are respectively fixedly connected to two connectors.

[0007] A further improvement is that a mounting column is fixedly installed at one corner of the first mounting base and the second mounting base, and the ends of the two adjusting cylinders are fixedly connected to the mounting column by fixing bolts. The first mounting base and the second mounting base are fixedly connected to the frame by fixing bolts.

[0008] A further improvement is that both mounting base one and mounting base two are fixedly mounted with protective covers, and the ports of the two protective covers are opposite each other.

[0009] A further improvement is that the adjusting blocking mechanism also includes a top surface limiting structure, which includes a guide groove fixedly installed on the frame and located on the side of each cover, a fine-tuning screw rotatably passing through each guide groove, and an upper stop rod threaded onto the two fine-tuning screws and mounted on the frame.

[0010] A further improvement is that the adjusting blocking mechanism also includes a side blocking structure, which includes side blocking rods disposed on both sides of a set of conveying rollers and several connecting plates fixedly installed on the side blocking rods at equal intervals. The surface of the connecting plates is provided with mounting and adjusting grooves.

[0011] A further improvement is that each of the baffles is made of silicone material, and the first and second swing arms are both Z-shaped.

[0012] Compared with the prior art, the beneficial effects of the present invention are: The pallet blocking mechanism design of this invention allows for a small contact area between the adjusting blocking mechanism and the pallet, effectively reducing wear caused by friction and avoiding problems such as deformation or jamming of the blocking plate. It is safe, stable, and reliable in use; easy to install and runs smoothly; it also has the function of adjusting the installation distance, which can be adapted to pallets of more sizes and has a wide range of applications; in addition, the design has a simple structure and low manufacturing cost.

[0015] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0016] like Figures 1 to 8 As shown, a novel pallet blocking mechanism includes a frame 2; Conveying assembly 1, located within frame 2, is used for conveying pallets; Specifically, the conveying assembly 1 includes a plurality of conveying rollers 11 rotatably disposed within the port of the frame 2; It should be noted that the conveying assembly 1 also includes a chain group, several sprockets, chain limiting guide rails, a drive device and other auxiliary parts, which are installed on the frame 2 before implementation. This part is existing technology and will not be described in detail in this embodiment. The adjusting blocking mechanism 4 is used for positioning the pallet. The adjusting blocking mechanism 4 includes a mounting base 1 42 and a mounting base 2 43 symmetrically fixedly connected to the frame 2, an adjusting cylinder 44 fixedly installed on the mounting base 1 42 and the mounting base 2 43, a swing arm 1 45 rotatably installed on the mounting base 1 42 via a rotating shaft, a swing arm 2 46 rotatably installed on the mounting base 2 43 via a rotating shaft, a baffle 47 fixedly installed on the inner side of the front end of the swing arm 1 45 and the swing arm 2 46, and a connector 48 fixedly installed at the end of the swing arm 1 45 and the swing arm 2 46. The rod ends of the two adjusting cylinders 44 are respectively fixedly connected to the two connectors 48. By activating the two sets of adjusting cylinders 44, their rods extend / retract simultaneously, causing the two connectors 48 to push the swing arm 1 45 and the swing arm 2 46 to rotate, thereby realizing the flow / blocking of the pallet. It should be noted that mounting posts 49 are fixedly installed at one corner of mounting base 42 and mounting base 43. The ends of the two adjusting cylinders 44 are fixedly connected to the mounting posts 49 by fixing bolts, which are used to adjust the cylinders 44 for disassembly and assembly. Both mounting base 1 (42) and mounting base 2 (43) have multiple sets of slotted mounting holes, which can be adjusted and fixed according to the actual target position of the pallet, so as to meet the blocking requirements of pallets of different sizes while ensuring safe and stable operation.

[0017] In this embodiment, there is also a preferred implementation: a protective cover 41 is fixedly installed on both the first mounting base 42 and the second mounting base 43. The ports of the two protective covers 41 are opposite each other. The protective cover 41 is used to protect each regulating cylinder 44 and can effectively protect the regulating cylinder 44 from being impacted by external objects.

[0018] In this embodiment, there is also a preferred implementation scheme. The adjusting blocking mechanism 4 further includes a top surface limiting structure 5. The top surface limiting structure 5 includes a guide groove 51 fixedly installed on the frame 2 and located on the side of each cover 41, a fine-tuning screw 52 rotatably passing through each guide groove 51, and an upper stop rod 53 threaded on the two fine-tuning screws 52 and mounted on the frame 2. By synchronously rotating the two fine-tuning screws 52, the upper stop rod 53 is finely adjusted up and down under the action of the fine-tuning screws 52 to achieve the top surface limiting effect.

[0019] In this embodiment, there is also a preferred implementation: the adjusting blocking mechanism 4 further includes a side blocking structure 3. The side blocking structure 3 includes side blocking rods 31 disposed on both sides of the surface of a set of conveying rollers 11 and several connecting plates 32 equidistantly fixedly installed on the side blocking rods 31. The surface of the connecting plates 32 is provided with mounting adjustment grooves 321, which are used to adjust the spacing between the blocking rods, thereby realizing the lateral limiting function. After adjustment, the connecting plates 32 are fixedly installed on the frame 2 using fastening bolts.

[0020] In this embodiment, it should also be noted that this application only addresses the shortcomings of the existing pallet blocking mechanism, such as low operational stability and safety, which affects the overall performance of the machine. It does not involve improvements in other aspects. The improvement is achieved by designing and adjusting the blocking mechanism 4 to solve the problems in the background technology.

[0021] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution will now be briefly explained in conjunction with specific application scenarios: The operation procedure for the field application of this invention is as follows: First, on-site personnel need to adjust and fix the position of a pair of side stop bars 31 in the side stop structure 3 according to the pallet size to achieve the lateral limiting function. Next, they synchronously rotate two fine-tuning screws 52, causing the upper stop bar 53 to be finely adjusted up and down under the action of the screws 52, achieving the top surface limiting effect. After completing the above operations, the pallet is placed on the conveyor roller 11, and the drive device drives the sprocket, chain assembly, and conveyor roller 11 to rotate, realizing the conveying of the pallet.

[0022] During pallet transport, there are two operating modes to meet different needs: To ensure smooth passage of the pallet, the two sets of adjusting cylinders 44 are activated, causing their rods to extend simultaneously. At this time, the two connectors 48 respectively push the first swing arm 45 and the second swing arm 46 to rotate, so that they are in a "retracted state", that is, the ends of the first swing arm 45 and the second swing arm 46 rotate to the surfaces of the first mounting base 42 and the second mounting base 43, ensuring that the pallet passes smoothly.

[0023] If it is necessary to block the pallet, the two sets of adjusting cylinders 44 are activated, causing their rods to retract simultaneously. At this time, the two connectors 48 drive the first swing arm 45 and the second swing arm 46 to rotate, so that they are in a "blocking state", that is, the connectors 48 are flush with the pallet, and the silicone baffles 47 inside the first swing arm 45 and the second swing arm 46 are tightly attached to the side of the pallet, thus completing the pallet blocking work.

[0024] The pallet blocking mechanism design of this invention allows for a small contact area between the adjusting blocking mechanism 4 and the pallet, effectively reducing wear caused by friction and avoiding problems such as deformation or jamming of the blocking plate. The process is safe, stable, and reliable; it is easy to install and runs smoothly; it also has the function of adjusting the installation distance, which can accommodate pallets of more sizes and has a wide range of applications; in addition, the design structure is simple and the manufacturing cost is low.

[0025] The above-disclosed embodiments are only a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
