Description

Technical Field

[0001] This utility model relates to the field of tobacco packing technology, and in particular to a chain plate punching and positioning device for a tobacco packing machine. Background Technology

[0002] The cigarette packing machine is a highly automated cigarette conveying production line that integrates mechanics, electricity, and pneumatics. It is used to transport finished cigarette packs, verify quality with detection probes, and cooperate with downstream machines to complete core actions in the entire automated cigarette production process.

[0003] like Figures 1-4 As shown, the cigarette packing machine includes a chain plate for conveying cigarettes and multiple cigarette baffles 200 disposed on the chain plate. The chain plate is composed of multiple chain plate bodies 100 connected in sequence. The cigarette baffles 200 are fixed above the chain plate bodies 100, and the distance between two adjacent cigarette baffles 200 is adapted to the length of the cigarette 600, used to place and limit the movement of the cigarette 600. A cigarette carrying surface 101 is provided on the top of the chain plate body 100 for carrying the cigarette 600. Adjacent chain plate bodies 100 are connected and fixed by wedge blocks 300. Specifically, one end of the chain plate body 100 is provided with a plugging protrusion 103, and the plugging protrusion 103 has a first through hole 1031. The other end of the chain plate body 100 is provided with a first plugging lug 104 and a second plugging lug 105, the first plugging lug 104 has a second through hole 1041, and the second plugging lug 105 has a third through hole 1051. When two adjacent chain plate bodies 100 are assembled, the plugging protrusion 103 of one chain plate body 100 is inserted between the first plugging lug 104 and the second plugging lug 105 of the other chain plate body 100. Then, the wedge block 300 is sequentially inserted into the second through hole 1041, the first through hole 1031, and the third through hole 1051, thereby connecting the two chain plate bodies 100. The cigarette bar baffle 200 is connected to the chain plate body 100 by a compression spring 400 and a countersunk screw 500. Specifically, the base of the cigarette bar baffle 200 is provided with two connecting holes 201, and the cigarette bar bearing surface 101 of the chain plate body 100 is provided with two fixing holes 102. The compression spring 400 is sleeved on the countersunk screw 500, and the two countersunk screws 500 pass through the two connecting holes 201 and are threadedly connected to the corresponding fixing holes 102, thus realizing the fixing of the cigarette bar baffle 200 and the chain plate body 100.

[0004] In existing technology, when processing the two fixing holes 102 on the chain plate body 100, the method of first drawing lines for positioning and then drilling is usually adopted. However, this drilling technique has problems such as inaccurate drilling position, non-parallelism between the center line of the two fixing holes 102 and the width direction of the chain plate (i.e., the direction perpendicular to the chain plate transport direction), and high defect rate. Inaccurate drilling position will cause the tobacco bar baffle 200 to be installed in an inaccurate position, resulting in insufficient transport space for the tobacco bar 600, causing the tobacco bar 600 to be squeezed and deformed. The fact that the center line connecting the two fixing holes 102 is not parallel to the width of the chain plate will cause the tobacco bar baffle 200 to be installed non-parallel to the chain plate. That is, the tobacco bar baffle 200 has an angle of inclination relative to the width direction of the chain plate, causing the tobacco bar 600 to be placed at an angle. Since there is a horizontal lifting track in the transportation of tobacco bar packing machine, the tobacco bar 600 needs to be lifted in conjunction with the outer frame baffle. If the tobacco bar 600 is tilted, it will cause the tobacco bar 600 to be squeezed and deformed by the outer frame baffle, thereby increasing the number of defective tobacco bars 600.

[0005] Therefore, there is an urgent need for a punching and positioning device for the chain plate of a cigarette packing machine to solve the above-mentioned technical problems. Utility Model Content

[0006] Based on the above, the purpose of this utility model is to provide a punching and positioning device for the chain plate of a cigarette packing machine, which can quickly and accurately locate the punching position when punching holes in the chain plate body, thus ensuring the accuracy of punching the chain plate body.

[0007] To achieve this objective, the present invention adopts the following technical solution:

[0008] The chain plate punching and positioning device for cigarette packing machine includes:

[0009] The first positioning plate has a first positioning surface at its bottom, which is used to fit against the cigarette bar bearing surface of the chain plate body; the first positioning plate also has two positioning holes arranged along a first direction, which are used to define the drilling positions of two fixing holes on the chain plate body, and the first direction is parallel to the width direction of the chain plate.

[0010] The second positioning plate is vertically connected to one end of the first positioning plate along the second direction. The second positioning plate has a second positioning surface on the side near the first positioning plate. The second positioning surface is used to abut against the periphery of the first and second insertion lugs of the chain plate body. The second direction is perpendicular to the first direction.

[0011] A positioning block is fixedly disposed between the first positioning plate and the second positioning plate. The positioning block is used to be inserted between the first insertion lug and the second insertion lug. The two ends of the positioning block are respectively provided with a third positioning surface and a fourth positioning surface. The third positioning surface is parallel to the inner end face of the first insertion lug, and the fourth positioning surface is parallel to the inner end face of the second insertion lug.

[0012] In some possible implementations, the first positioning surface is in close contact with the cigarette bar bearing surface; the third positioning surface is in clearance fit with the inner end face of the first insertion lug, with a gap of 0.5mm; the fourth positioning surface is in clearance fit with the inner end face of the second insertion lug, with a gap of 0.5mm.

[0013] In some possible implementations, the first positioning plate and the second positioning plate are integrally formed by bending metal plates, and the positioning block is fixed between the first positioning plate and the second positioning plate by welding.

[0014] In some possible implementations, the positioning block is a cylinder, and the two end faces of the cylinder are the third positioning surface and the fourth positioning surface, respectively.

[0015] In some possible implementations, the first positioning surface is rectangular in shape.

[0016] In some possible implementations, the length of the first positioning surface is 550 mm and the width is 430 mm.

[0017] In some possible implementations, the second positioning surface is rectangular in shape.

[0018] In some possible implementations, the second positioning surface has a length of 430 mm and a width of 200 mm.

[0019] In some possible implementations, the radius of the third positioning surface is 4 mm.

[0020] In some possible implementations, the radius of the fourth positioning surface is 4 mm.

[0021] The beneficial effects of this utility model are:

[0022] The positioning device for drilling holes in the chain plate of the cigarette packing machine provided by this utility model involves placing the first positioning plate on the chain plate body, making the first positioning surface fit against the cigarette carrying surface of the chain plate body, and then pushing the second positioning plate so that the positioning block is inserted between the first and second insertion lugs of the chain plate body until the second positioning surface abuts against the periphery of the first and second insertion lugs. At this time, the positions of the two positioning holes on the first positioning plate are the positions of the two fixing holes that need to be processed on the chain plate body, thus completing the positioning for drilling holes in the chain plate body.

[0023] This invention uses the aforementioned positioning device to position the chain plate body and, in conjunction with a drilling machine, to drill holes. The operation is simple, the positioning is fast and accurate, and the accuracy of the drilling position is improved, thereby increasing the installation accuracy of the cigarette bar baffle. This provides sufficient space for cigarette bar transportation, preventing cigarette bar compression due to insufficient transportation space. Simultaneously, the two positioning holes are arranged along the first direction, improving the parallelism between the line connecting the centers of the two fixing holes and the width direction of the chain plate. This reduces the occurrence of non-parallel installation of the cigarette bar baffle and the chain plate, meaning the cigarette bar baffle has no tilt angle relative to the width direction of the chain plate, preventing cigarette bar tilting, reducing the compression of cigarette bars against the outer frame baffle, and decreasing the number of defective cigarette bars.

Detailed Implementation

[0033] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0034] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0035] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0036] In the description of this utility model, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are merely used for distinction in description and have no special meaning.

[0037] This embodiment provides a chain plate punching and positioning device for a cigarette packing machine, which is used to position the punching operation of the chain plate body 100 to solve the problems of inaccurate punching position of the chain plate body 100, non-parallelism between the center line of the two fixing holes 102 and the width direction of the chain plate, and high defect rate in the prior art.

[0038] like Figure 5 and Figure 6 As shown, this embodiment provides a punching and positioning device for a chain plate of a cigarette packing machine, including a first positioning plate 1, a second positioning plate 2, and a positioning block 3. The bottom surface of the first positioning plate 1 is a first positioning surface 11, which is used to fit against the cigarette packing surface 101 of the chain plate body 100. The first positioning plate 1 also has two positioning holes 12 arranged along a first direction, which are used to define the punching positions of two fixing holes 102 on the chain plate body 100. Specifically, the diameter of the positioning hole 12 is slightly larger than the diameter of the fixing hole 102, so that the drill bit of the drilling machine can pass through the positioning hole 12 to punch holes in the chain plate body 100. In this embodiment, the first direction is parallel to the width direction of the chain plate. The second positioning plate 2 is vertically connected to one end of the first positioning plate 1 along a second direction. The second positioning plate 2 has a second positioning surface 21 on the side near the first positioning plate 1, which is used to abut against the periphery of the first insertion lug 104 and the second insertion lug 105 of the chain plate body 100. In this embodiment, the second direction is perpendicular to the first direction. The positioning block 3 is fixedly disposed between the first positioning plate 1 and the second positioning plate 2. The positioning block 3 is used to be inserted between the first insertion lug 104 and the second insertion lug 105. The two ends of the positioning block 3 are respectively provided with a third positioning surface 31 and a fourth positioning surface 32. The third positioning surface 31 is parallel to the inner end face of the first insertion lug 104, and the fourth positioning surface 32 is parallel to the inner end face of the second insertion lug 105.

[0039] The chain plate punching and positioning device for the cigarette packing machine provided in this embodiment is used by placing the first positioning plate 1 on the chain plate body 100, so that the first positioning surface 11 is in contact with the cigarette carrying surface 101 of the chain plate body 100. Then, the second positioning plate 2 is pushed so that the positioning block 3 is inserted between the first insertion lug 104 and the second insertion lug 105 of the chain plate body 100 until the second positioning surface 21 is pressed against the periphery of the first insertion lug 104 and the second insertion lug 105. At this time, the positions of the two positioning holes 12 on the first positioning plate 1 are the positions of the two fixing holes 102 that need to be processed on the chain plate body 100. In this way, the positioning of the punching of the chain plate body 100 is completed.

[0040] In this embodiment, the chain plate body 100 is positioned using the aforementioned positioning device and drilled using a drilling machine. The operation is simple, the positioning is fast and accurate, and the accuracy of the drilling position is improved, thereby improving the installation accuracy of the cigarette bar baffle 200. Sufficient space is reserved for the transportation of the cigarette bar 600, avoiding the compression of the cigarette bar 600 due to insufficient transportation space. At the same time, the two positioning holes 12 are arranged along the first direction, which improves the parallelism between the center line of the two fixed holes 102 and the width direction of the chain plate. This reduces the occurrence of non-parallel installation of the cigarette bar baffle 200 and the chain plate. That is, the cigarette bar baffle 200 has no tilt angle relative to the width direction of the chain plate, avoiding the tilting of the cigarette bar 600, reducing the compression of the cigarette bar 600 with the outer frame baffle, and reducing the number of defective cigarette bars 600.

[0041] In this embodiment, the first positioning surface 11 is tightly fitted against the cigarette bar bearing surface 101 to allow the drilling machine to drill holes in the chain plate body 100. The third positioning surface 31 is clearance-fitted with the inner end face of the first insertion lug 104, and the fourth positioning surface 32 is clearance-fitted with the inner end face of the second insertion lug 105, so that the positioning block 3 can be smoothly inserted between the first insertion lug 104 and the second insertion lug 105. It should be noted that if the above gaps are too large, the positioning block 3 will lose its positioning function; if the gaps are too small, the movement of the positioning block 3 will be stuck. In this embodiment, preferably, the gap between the third positioning surface 31 and the inner end face of the first insertion lug 104 is 0.5mm, and the gap between the fourth positioning surface 32 and the inner end face of the second insertion lug 105 is 0.5mm, which is a reasonable design and reliable positioning. Of course, in other embodiments, the above gaps can also be set to other values, as long as the positioning reliability and smooth movement of the positioning block 3 can be guaranteed, and are not limited to this embodiment.

[0042] Optionally, the positioning device in this embodiment is an integral structure. Specifically, the first positioning plate 1 and the second positioning plate 2 are integrally formed by bending metal plates, and the positioning block 3 is fixed between the first positioning plate 1 and the second positioning plate 2 by welding. This configuration is simple in structure, easy to process, and ensures the structural strength of the positioning device.

[0043] Optionally, in this embodiment, the positioning block 3 is cylindrical, with its two end faces being a third positioning surface 31 and a fourth positioning surface 32, respectively; that is, both the third positioning surface 31 and the fourth positioning surface 32 are circular. Since the first insertion lug 104 and the second insertion lug 105 of the existing chain plate body 100 are typically circular, the circular third positioning surface 31 and the fourth positioning surface 32 provide a more reasonable fit with the first insertion lug 104 and the second insertion lug 105, resulting in more accurate positioning. For example, in this embodiment, the radius of the third positioning surface 31 is 4mm, and the radius of the fourth positioning surface 32 is also 4mm.

[0044] Optionally, in this embodiment, the first positioning surface 11 is rectangular in shape, which is simple in structure, easy to process, and more compatible with the tobacco strip bearing surface 101 of the chain plate body 100. Specifically, the length of the first positioning surface 11 is 550mm and the width is 430mm. Further, in this embodiment, the second positioning surface 21 is also rectangular in shape, and the dimension of the second positioning surface 21 along the first direction is equal to the dimension of the first positioning surface 11 along the first direction. For example, the length of the second positioning surface 21 is 430mm and the width is 200mm.

[0045] This embodiment uses a positioning device to position the drilling of the chain plate body 100, which improves upon the previous manual measurement and positioning drilling method to a certain extent. This effectively reduces drilling errors, decreases the number of defective chain plate bodies 100, and improves drilling efficiency. Moreover, it avoids the situation where incorrect drilling positions lead to incorrect installation positions of the tobacco stick baffle 200, ultimately resulting in damage and deformation of the tobacco stick 600. The two fixing holes 102 processed by this positioning device are accurately positioned, ensuring the subsequent installation accuracy of the compression spring 400, countersunk screw 500, and tobacco stick baffle 200. After installation and debugging, they can accurately meet the relevant technical requirements.

[0046] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
