Description
Technical Field
[0001] The utility model relates to the technical field of tobacco packaging machines, in particular to a double-layer retractable push handle structure. Background Art
[0002] The push handle structure on the tobacco packaging machine is an important part of the packaging machinery. It is mainly responsible for pushing tobacco products (such as cigarettes) from the production line to the packaging position to ensure that the products can be accurately packaged. The design of this structure needs to ensure the stability, accuracy and continuity of the product during the transmission process. The push handle structure usually includes a push handle frame, a push handle plate, a transmission mechanism and a control system. The original push handle structure was designed to handle single-layer materials, which limits its application ability when handling multi-layer or complex stacked materials. In modern production lines, multi-layer material stacking is very common, such as multi-layer cigarette boxes or irregularly stacked products. This limitation not only reduces the flexibility of the production line, but may also lead to reduced production efficiency.
[0003] In addition, the original push handle structure also has strict requirements on the shape and size of the material. It can usually only handle materials with regular shapes and uniform sizes. For materials with irregular shapes or variable sizes, the original push handle structure often cannot push accurately, which may cause the material to be misplaced, dumped or scattered during the pushing process, thereby affecting the accuracy of subsequent packaging steps. Utility Model Content
[0004] In view of the above-mentioned deficiencies existing in current tobacco packaging machines, the utility model provides a double-layer retractable push handle structure, which can ensure accurate pushing of double-layer materials and reduce the impact and damage that may be caused to the materials due to sudden stop.
[0005] In order to achieve the above object, the embodiment of the utility model adopts the following technical solution:

[0012] According to one aspect of the utility model, the bracket is fixedly connected to the stopper by screws; and the guide rod is fixedly connected to the pusher plate by bolts.
[0013] Advantages of the implementation of the utility model: The utility model allows the push plate to be adaptively adjusted when encountering materials that are dislocated up and down by setting a spring and an upper and lower double-layer push plate, ensuring that each layer of material can be accurately pushed and improving the fault tolerance of the equipment; when pushing double-layer materials, the compression force of the spring helps to level the material and reduce the distortion or deformation of the material during the transmission process. When the material is pushed to the positioning reference surface, it will rebound due to inertia. At this time, the contraction of the spring plays a buffering role, reducing the impact and damage that the material may suffer due to sudden stop. This buffering mechanism not only protects the material, but also extends the service life of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the utility model provides a double-layer retractable push handle structure, including a bracket 1 and a push handle assembly arranged at the bottom of the bracket 1, wherein the push handle assembly includes a stopper 2, a push handle plate and a guide rod, and the push handle plate includes an upper push handle plate 3 and a lower push handle plate 31, and is in an upper and lower layer and independently designed. The double-layer push handle plate can adapt to products with different stacking methods, such as double-layer stacked cigarette boxes or other multi-layer materials. This flexibility enables the production line to handle more types of products without frequent replacement or adjustment of equipment. By optimizing the design of the double-layer push handle plate, the impact and collision of materials during the pushing process can also be reduced, thereby reducing the scrap rate.
[0026] The block 2 is provided with a plurality of through holes, and the bottom of the bracket 1 is provided with openings corresponding to the through holes; the guide rod passes through the openings and through holes in sequence and is then fixedly connected to the push plate; an inner steel ball holder 11 and an outer steel ball holder 10 are provided between the guide rod and the block 2, and a spring 21 is provided between the outer steel ball holder 10 and the block 2. In the process of pushing the push plate, the spring 21 is compressed to achieve the effect of leveling, and when the positioning reference surface is derived, the material generally rebounds a certain distance due to inertia, and at this time the spring 21 contracts, which plays a good protective role.
[0027] In practical applications, the guide rod includes an upper guide rod and a lower guide rod, the upper guide rod includes a first upper guide rod 4 and a second upper guide rod 41, the lower guide rod includes a first lower guide rod 5 and a second lower guide rod 51, the first upper guide rod 4 and the second upper guide rod 41 are placed in the same horizontal plane, the first lower guide rod 5 and the second lower guide rod 51 are placed in the same horizontal plane, and the upper guide rod and the lower guide rod are arranged in parallel up and down.
[0028] The through holes include an upper through hole, a lower through hole, a first bolt hole 8, a second bolt hole 81 and a third bolt hole 82. The upper through hole includes a first upper through hole 6 and a second upper through hole 61. The lower through hole includes a first lower through hole 7 and a second lower through hole 71. The first upper guide rod 4 is arranged in the first upper through hole 6, the second upper guide rod 41 is arranged in the second upper through hole 61, the first lower guide rod 5 is arranged in the first lower through hole 7, and the second lower guide rod 51 is arranged in the second lower through hole 71.
[0029] The openings include a first opening 9, a second opening 91, a third opening 92, a fourth opening 93, a fifth opening 94, a sixth opening 95 and a seventh opening 96; the first opening 9, the second opening 91 and the third opening 92 correspond to the first bolt hole 8, the second bolt hole 81 and the third bolt hole 82 respectively; the fourth opening 93, the fifth opening 94, the sixth opening 95 and the seventh opening 96 correspond to the first upper through hole 6, the second upper through hole 61, the first lower through hole 7 and the second lower through hole 71 respectively.
[0030] The upper push handle plate 3 is provided with a first through hole 311 and a second through hole 312, and the lower push handle plate 31 is provided with a third through hole 313 and a fourth through hole 314. The central axes of the first through hole 311, the first upper through hole 6, and the fourth opening 93 are on the same axis; the central axes of the third through hole 313, the first lower through hole 7, and the sixth opening 95 are on the same axis. The guide rod is fixedly connected to the push handle plate by bolts. Therefore, the overall installation structure is that the first upper guide rod 4 passes through the fourth opening 93 and the first upper through hole 6 in sequence, and is fixedly connected in the first penetration hole 311 by bolts; the second upper guide rod 41 passes through the fifth opening 94 and the second upper through hole 61 in sequence, and is fixedly connected in the second penetration hole 312 by bolts; the first lower guide rod 5 passes through the sixth opening 95 and the first lower through hole 7 in sequence, and is fixedly connected in the third penetration hole 313 by bolts; the second lower guide rod 51 passes through the seventh opening 96 and the second lower through hole 71 in sequence, and is fixedly connected in the fourth penetration hole 314 by bolts; an inner steel ball retainer 11 and an outer steel ball retainer 10 are provided between each guide rod and the stopper 2, a part of the outer steel ball retainer 10 is provided between the guide rod and the stopper 2, and a part is exposed to the outside, and a spring 21 is provided on the outside of the part of the outer steel ball retainer 10 provided between the guide rod and the stopper 2.
[0031] In practical applications, the bracket 1 is an L-shaped bracket 1 , and a reinforcement plate 12 is fixedly connected to the bracket 1 .

[0033] The push plate in the double-layer retractable push handle structure of the utility model reciprocates left and right under the drive of the transmission shaft. Due to the reciprocating speed of 600 times per minute and the large inertia, it is easy to cause the product to be crushed under the action of impact force. The utility model allows the push plate to be adaptively adjusted when encountering materials that are dislocated up and down by setting springs and upper and lower double-layer push plates, ensuring that each layer of materials can be accurately pushed and improving the fault tolerance of the equipment; when pushing double-layer materials, the compression force of the spring helps to flatten the materials and reduce the distortion or deformation of the materials during the transmission process. When the materials are pushed to the positioning reference surface, they will rebound due to inertia. At this time, the contraction of the spring plays a buffering role, reducing the impact and damage that the materials may suffer due to sudden stop. This buffering mechanism not only protects the materials, but also extends the service life of the equipment. The utility model enables the tobacco packaging machine to handle more types and shapes of materials, including those that are easily dislocated or deformed, by improving the design of the push plate, which greatly broadens the application range of the equipment and improves its market competitiveness.
[0034] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model shall be based on the protection scope of the claims.
