Description

Technical Field

[0001] This utility model relates to the field of cigarette packaging machine debugging technology, and in particular to a positioning device. Background Technology

[0002] The ZB48A packaging machine (ZB48A hard-pack and hard-strip packaging unit) is a high-speed piece of equipment used in domestic cigarette production for hard-pack and hard-strip packaging. Its main function is to process pre-formed cigarettes (produced by the ZJ116A cigarette-making unit) through operations such as cigarette pack forming, sealing, labeling, and boxing, ultimately creating complete finished cigarette packs. During operation, a cylinder-driven steel plate clamping device is typically used to ensure the stability of the cigarettes or packs during high-speed movement. When performing maintenance or repairs on the conveyor belt or cylinders at the packaging machine's inlet conveyor channel, the cylinders need to be removed. After maintenance, the cylinder position (the size of the conveyor channel) needs to be adjusted to prevent cylinder misalignment from affecting the continuous supply of cigarette packs or causing damage to the packs.

[0003] However, in the existing technology, the inlet conveying channel of the packaging machine generally includes an inner conveying channel and an outer conveying channel. The components of the two conveying channels are related. When the position of the cylinder in one conveying channel is adjusted, the width of the other conveying channel will also be affected. The adjustment is difficult and requires repeated manual measurement and debugging. At the same time, a large amount of waste smoke is generated during the repeated debugging process. The waste smoke inside the equipment also needs to be cleaned manually. The whole debugging process is time-consuming and labor-intensive. Utility Model Content

[0016] The beneficial effects of this utility model are:

[0017] This utility model provides a positioning device. A first adjusting component is provided within a first channel of a packaging machine's cylinder clamping channel. Both ends of the first adjusting component abut against a first sidewall of the first channel and a first cylinder guide bar, respectively. A first contouring portion is provided on the first adjusting component, adapted to fit the outer surface of the first cylinder guide bar facing the first sidewall. This ensures a tight fit between the first contouring portion and the first cylinder guide bar. Simultaneously, the dimension of the first adjusting component in the first direction is set to be equal to a first preset dimension. Furthermore, a second adjusting component is provided within a second channel of the packaging machine's cylinder clamping channel. Both ends of the second adjusting component abut against a second sidewall of the second channel and a second cylinder guide bar, respectively. A second contouring portion is provided on the second adjusting component, adapted to fit the outer surface of the second cylinder guide bar facing the second sidewall. This ensures a tight fit between the second contouring portion and the second cylinder guide bar. Simultaneously, the dimension of the second adjusting component in the first direction is set to be equal to a second preset dimension. This allows for the following: when the dimensions of the cylinder clamping channels (i.e., the first channel and the second channel) need to be positioned, the first adjustment component can be placed in the first channel, and the second adjustment component can be placed in the second channel. Then, the dimensions (widths) of the first and second channels can be positioned. Since the dimension of the first adjustment component in the first direction is the first preset dimension, when the first sidewall and the first cylinder guide bar in the first channel simultaneously abut against both ends of the first adjustment component, it indicates that the dimension of the first channel is also the first preset dimension, that is, the dimension of the first channel has been adjusted to the correct position. Similarly, since the dimension of the second adjustment component in the first direction is the second preset dimension, when the second sidewall and the second cylinder guide bar in the second channel simultaneously abut against both ends of the second adjustment component, it indicates that the dimension of the second channel is also the second preset dimension, that is, the dimension of the second channel has been adjusted to the correct position. In the process of positioning the cylinder clamping channel using the above-mentioned positioning device, the original "measurement operation" (measuring the size of the cylinder clamping channel with measuring tools and then positioning) is changed to a "comparison operation" (comparing the size of the cylinder clamping channel with the size of the adjustment component; that is, when the size of the cylinder clamping channel is the same as the size of the adjustment component, it means that the size is positioned correctly; otherwise, it means that the size is not positioned correctly). This makes the positioning operation simpler and more intuitive. Furthermore, in the process of positioning the cylinder clamping channel using the above-mentioned positioning device, the size of the first channel and the second channel can be positioned simultaneously without repeated adjustments, saving manpower and resources and improving work efficiency.

[0033] Combination Figure 1 , Figure 2 As shown, this embodiment provides a positioning device for positioning the size of the cylinder clamping channel 1 of a packaging machine. The cylinder clamping channel 1 includes a first channel 11 composed of a first sidewall 111 and a first cylinder guide bar 112, and a second channel 12 composed of a second sidewall 121 and a second cylinder guide bar 122. The extending direction of the first channel 11 is parallel to the extending direction of the second channel 12.

[0034] The aforementioned positioning device includes a first adjustment component 2 and a second adjustment component 3. (As in combination...) Figure 1 , Figure 2 As shown, the first adjustment component 2 is disposed in the first channel 11 and extends along a first direction X1. This first direction X1 is perpendicular to the extending direction of the first channel 11; in other words, the first direction X1 is perpendicular to the conveying direction of the first channel 11. The two ends of the first adjustment component 2 in the first direction X1 abut against the first sidewall 111 and the first cylinder guide bar 112, respectively. That is, with... Figure 2 Taking the shown perspective as an example, the left end of the first adjustment component 2 can abut against the first sidewall 111, and the right end of the first adjustment component 2 can abut against the first cylinder guide bar 112. The first adjustment component 2 is provided with a first contouring part 21, which is adapted to the outer surface of the first cylinder guide bar 112 facing the first sidewall 111. That is, with... Figure 2 Taking the shown perspective as an example, the first adjustment component 2 is provided with a first contouring part 21 at the end (right end) that abuts against the first cylinder guide bar 112. The shape and size of the first contouring part 21 are the same as the shape and size of the outer side of the left side of the first cylinder guide bar 112.

[0035] In the first direction X1, the size of the first channel 11 is a first preset size, and the size of the first adjustment component 2 is equal to the first preset size. In other words, the width of the first adjustment component 2 is the preset width after the first channel 11 is fully adjusted.

[0036] Combination Figure 1 , Figure 2 As shown, the second adjustment component 3 is disposed in the second channel 12 and extends along the first direction X1. The two ends of the second adjustment component 3 in the first direction X1 abut against the second sidewall 121 and the second cylinder guide bar 122, respectively. That is, with... Figure 2 Taking the shown perspective as an example, the left end of the second adjustment component 3 can abut against the second sidewall 121, and the right end of the second adjustment component 3 can abut against the second cylinder guide bar 122. The second adjustment component 3 is provided with a second contouring part 31, which is adapted to the outer surface of the second cylinder guide bar 122 facing the second sidewall 121. That is, with... Figure 2 Taking the shown perspective as an example, the second adjustment component 3 is provided with a second contouring part 31 at the end (right end) that abuts against the second cylinder guide bar 122. The shape and size of the second contouring part 31 are the same as the shape and size of the outer side of the left side of the second cylinder guide bar 122.

[0037] In the first direction X1, the size of the second channel 12 is a second preset size, and the size of the second adjustment component 3 is equal to the second preset size. In other words, the width of the second adjustment component 3 is the preset width after the second channel 12 is fully adjusted.

[0038] Therefore, the positioning device provided in this embodiment provides a first adjusting component 2 within the first channel 11 of the cylinder clamping channel 1 of the packaging machine. The two ends of the first adjusting component 2 abut against the first sidewall 111 and the first cylinder guide bar 112 forming the first channel 11, respectively. A first contouring part 21 is provided on the first adjusting component 2, and the first contouring part 21 is configured to fit the outer side of the first cylinder guide bar 112 facing the first sidewall 111. This allows the first contouring part 21 to fit tightly against the first cylinder guide bar 112. Simultaneously, the dimensions of the first adjusting component 2 in the first direction X1 are set to be equal. The second adjustment component 3 is provided in the second channel 12 of the cylinder clamping channel 1 of the packaging machine. The two ends of the second adjustment component 3 abut against the second side wall 121 and the second cylinder guide 122 that make up the second channel 12, respectively. A second contouring part 31 is provided on the second adjustment component 3. The second contouring part 31 is adapted to the outer side of the second cylinder guide 122 that faces the second side wall 121. This allows the second contouring part 31 to fit tightly against the second cylinder guide 122. At the same time, the size of the second adjustment component 3 in the first direction X1 is set to be equal to the second preset size. This allows the first adjusting component 2 to be placed in the first channel 11 and the second adjusting component 3 in the second channel 12 when the dimensions of the cylinder clamping channel 1 (i.e., the first channel 11 and the second channel 12) need to be positioned. Then, the dimensions (widths) of the first channel 11 and the second channel 12 are positioned. Since the dimension of the first adjusting component 2 in the first direction X1 is the first preset dimension, when the first sidewall 111 and the first cylinder guide 112 in the first channel 11 simultaneously abut against the two ends of the first adjusting component 2, it indicates that the dimension of the first channel 11 is also the first preset dimension at this moment, that is, the dimension of the first channel 11 has been adjusted to the correct position. Similarly, since the dimension of the second adjusting component 3 in the first direction X1 is the second preset dimension, when the second sidewall 121 and the second cylinder guide 122 in the second channel 12 simultaneously abut against the two ends of the second adjusting component 3, it indicates that the dimension of the second channel 12 is also the second preset dimension at this moment, that is, the dimension of the second channel 12 has been adjusted to the correct position. In the process of positioning the cylinder clamping channel 1 using the above-mentioned positioning device, the original "measurement operation" (measuring the size of the cylinder clamping channel 1 with a measuring tool and then positioning) is changed to a "comparison operation" (comparing the size of the cylinder clamping channel 1 with the size of the adjustment component; that is, when the size of the cylinder clamping channel 1 is the same as the size of the adjustment component, it means that the size is positioned correctly; otherwise, it means that the size is not positioned correctly). This makes the positioning operation simpler and more intuitive. Furthermore, in the process of positioning the size of the cylinder clamping channel 1 using the above-mentioned positioning device, the size of the first channel 11 and the second channel 12 can be positioned simultaneously without repeated adjustments, saving manpower and resources and improving work efficiency.

[0039] In some embodiments, such as Figure 2 , Figure 3 As shown, the first conforming portion 21 includes a first abutting portion 211 and a first limiting portion 212. There are two first limiting portions 212, positioned on opposite sides of the first abutting portion 211 in the second direction X2. The second direction X2 forms an angle with the first direction X1 mentioned above, for example, 90°. Figure 1 As shown, to avoid damaging the cigarette pack, the outer side of the first cylinder guide 112 facing the first sidewall 111 typically has a strip-shaped contact portion 27 protruding from this outer side. This strip-shaped contact portion 27 is made of a flexible material (e.g., rubber). During positioning, the first abutting portion 211 abuts against the strip-shaped contact portion 27, and two first limiting portions 212 are located on the upper and lower sides of the strip-shaped contact portion 27, respectively. Furthermore, the connection between the first abutting portion 211 and the first limiting portion 212 is a right-angle transition. This arrangement allows the first contouring portion 21 to better fit the outer side of the first cylinder guide 112 facing the first sidewall 111, ensuring a tighter fit between the first contouring portion 21 and the first cylinder guide 112. This prevents gaps between the two from causing deviations in the dimensional positioning of the first channel 11, thus improving the positioning accuracy of the aforementioned positioning device. Meanwhile, the above-mentioned arrangement enables the first contouring part 21 to limit the first adjustment component 2 by cooperating with the strip-shaped contact part 27 on the first cylinder guide bar 112 through the two first limiting sub-parts 212. That is, the first contouring part 21 provided at one end of the first adjustment component 2 is locked in the first cylinder guide bar 112, preventing the position of the first adjustment component 2 from shifting in the second direction X2, and further ensuring the accuracy of the positioning device.

[0040] In some embodiments, such as Figure 2 , Figure 3As shown, the second conforming portion 31 includes a second abutting portion 311 and a second limiting portion 312. There are two second limiting portions 312, positioned on opposite sides of the second abutting portion 311 in the second direction X2, which forms an angle with the first direction X1 mentioned above, for example, 90°. It is easy to understand that, to avoid damaging the cigarette pack, the second cylinder guide strip 122 also has a protruding strip-shaped contact portion 27 on the outer side of the second sidewall 121, made of a flexible material (e.g., rubber). During positioning, the second abutting portion 311 abuts against the strip-shaped contact portion 27, with the two second limiting portions 312 located on the upper and lower sides of the strip-shaped contact portion 27, respectively. Furthermore, the connection between the second abutting portion 311 and the second limiting portion 312 is a right-angle transition. This configuration allows the second contouring part 31 to better fit the outer side of the second cylinder guide 122 facing the second sidewall 121, ensuring a tighter fit between them and preventing gaps that could cause dimensional deviations in the second channel 12. This further improves the positioning accuracy of the positioning device. Simultaneously, this configuration allows the second contouring part 31 to limit the second adjustment component 3 through the cooperation of two second limiting sub-parts 312 with the strip-shaped contact part 27 on the second cylinder guide 122. Specifically, the second contouring part 31 at one end of the second adjustment component 3 engages with the second cylinder guide 122, preventing positional shifts in the second direction X2 and further ensuring the positioning accuracy of the positioning device.

[0041] In some embodiments, such as Figure 2 , Figure 3 As shown, the first adjustment assembly 2 includes a first main body 22 and a first positioning member 23 arranged along the first direction X1. One end of the first main body 22 abuts against the first sidewall 111, and the other end is detachably connected to the first positioning member 23. A first contouring portion 21 is provided on the side of the first positioning member 23 opposite to the first main body 22. And / or, the second adjustment assembly 3 includes a second main body 32 and a second positioning member 33 arranged along the first direction X1. One end of the second main body 32 abuts against the second sidewall 121, and the other end is detachably connected to the second positioning member 33. A second contouring portion 31 is provided on the side of the second positioning member 33 opposite to the second main body 32. With this configuration, the first adjustment component 2 and / or the second adjustment component 3 can be set separately. When the first positioning component 23 and / or the second positioning component 33 are damaged, the first positioning component 23 can be separated from the first main body component 22 and / or the second positioning component 33 can be separated from the second main body component 32, and the first positioning component 23 and / or the second positioning component 33 can be replaced separately, thus saving material costs.

[0042] In some embodiments, such as Figure 2 , Figure 4 As shown, the first main body 22 near the first positioning member 23 and the first positioning member 23 near the first main body 22 each have a first connecting groove 221 and a first connecting protrusion 231, respectively. In other words, the first main body 22 near the first positioning member 23 has either a first connecting protrusion 231 or a first connecting groove 221, and the first positioning member 23 near the first main body 22 has either a first connecting groove 221 or a first connecting protrusion 231. The first connecting protrusion 231 and the first connecting groove 221 are adapted to each other; for example, the first connecting protrusion 231 is a dovetail-shaped protrusion, and the first connecting groove 221 is a dovetail-shaped groove. The first main body 22 and the first positioning member 23 can be detachably connected through the cooperation of the first connecting protrusion 231 and the first connecting groove 221.

[0043] And / or, one of the second main body 32 near the second positioning member 33 and the other of the second positioning member 33 near the second main body 32 are provided with a second connecting groove 321, and the other is provided with a second connecting protrusion 331. In other words, the second main body 32 near the second positioning member 33 is provided with a second connecting protrusion 331 or a second connecting groove 321, and the second positioning member 33 near the second main body 32 is provided with a second connecting groove 321 or a second connecting protrusion 331. The second connecting protrusion 331 is adapted to the second connecting groove 321. For example, the second connecting protrusion 331 is a dovetail-shaped protrusion, and the second connecting groove 321 is a dovetail-shaped groove. The second main body 32 and the second positioning member 33 can be detachably connected through the cooperation of the second connecting protrusion 331 and the second connecting groove 321.

[0044] With the above settings, the first main body 22 and the first positioning part 23, and the second main body 32 and the second positioning part 33 can be detachably connected, which is simple in structure and easy to use.

[0045] In some embodiments, there are multiple first positioning members 23, each with different dimensions in the first direction X1, and one of the multiple first positioning members 23 is selectively connected to the first main body member 22. In the first direction X1, the sum of the dimensions of the first main body member 22 and the first positioning member 23 equals a first preset dimension. And / or, there are multiple second positioning members 33, each with different dimensions in the first direction X1, and one of the multiple second positioning members 33 is selectively connected to the second main body member 32. In the first direction X1, the sum of the dimensions of the second main body member 32 and the second positioning member 33 equals a second preset dimension. With this configuration, when the first channel 11 and / or the second channel 12 are sized to accommodate different products, i.e., when the first preset size and / or the second preset size change, only the first positioning component 23 and / or the second positioning component 33 of the appropriate size need to be replaced. There is no need to remanufacture the entire first adjustment assembly 2 and / or the second adjustment assembly 3, saving material costs. This allows the first adjustment assembly 2 and / or the second adjustment assembly 3 to adapt to different cylinder clamping channels 1, improving the applicability of the above positioning device.

[0046] In some embodiments, such as Figure 3 , Figure 5As shown, the positioning device further includes a first adjusting member 24 extending along a first direction X1, which is disposed between the first main body member 22 and the first positioning member 23. The two ends of the first adjusting member 24 are detachably connected to the first main body member 22 and the first positioning member 23, respectively. The first adjusting member 24 can adjust the distance between the first main body member 22 and the first positioning member 23.
