The embodiments described below with reference to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.
[0036] The following will be combined with Figures 1 - 4 and further illustrate the technical solution of the present utility model through specific implementation manners.
[0037] During the packaging process of cigarette packs, the wrapping of the transparent paper outside the cigarette pack is achieved by installing a transparent paper roll on the paper rack of the packaging machine. The cigarette pack enters the stacking and lifting table, and the stacker lifts the cigarette pack upward. During the lifting process, the folding device folds the upper wing transparent paper at both ends of the cigarette pack downward. During this process, the stopper 2 on the folding device is pressed into the folding device by the cigarette pack under the action of the spring. After the cigarette pack passes through the folding device, the stopper 2 will pop out under the action of the spring. The spring is directly installed on the side of the stopper 2 and the folding device corresponding to the side of the stopper 2. In actual production, the movement frequency of the stopper 2 is very high. After long-term operation, the spring is prone to aging and failure, and the parts of the folding device in contact with the spring will wear. However, the installation space for the spring on the folding device is small, and it is difficult to replace the spring, resulting in a long time for each spring replacement and low work efficiency.
[0038] To solve the above problems, an embodiment of the present utility model provides a folding device, which includes a folding frame 1, a stopper 2, a positioning component, and an elastic member 4. The folding frame 1 is provided with a receiving cavity 11, and the receiving cavity 11 has an opening facing the cigarette pack passage; the stopper 2 is rotatably connected to the side wall of the receiving cavity 11, and at least part of the stopper 2 protrudes from the opening to the outside of the receiving cavity 11; the positioning component includes two positioning members 3, one of the positioning members 3 is detachably arranged on the side wall of the receiving cavity 11 opposite to the opening, and the other positioning member 3 is detachably arranged on the stopper 2, and the two positioning members 3 are arranged opposite to each other; both ends of the elastic member 4 are fixedly arranged on the two positioning members 3 respectively. By fixedly arranging the elastic member 4 on the positioning member 3, and the positioning member 3 is detachably arranged on the folding frame 1 and the stopper 2, when replacing the elastic member 4, only need to detach the positioning member 3 from the folding device, and then replace the elastic member 4, which increases the operation space and improves the replacement efficiency of the elastic member 4. Moreover, by installing the elastic member 4 on the folding frame 1 and the stopper 2 through the positioning member 3, it avoids the direct contact between the elastic member 4 and the folding frame 1 and the stopper 2, reduces the wear of the installation positions of the elastic member 4 on the folding frame 1 and the stopper 2, and if the corresponding installation position of the elastic member 4 on the positioning member 3 is worn, the positioning member 3 can be directly replaced, reducing the maintenance time and improving the work efficiency.
[0039] As Figures 2 - 4 shown, in this embodiment, positioning grooves 5 are provided on both the folding frame 1 and the stopper 2. The positioning member 3 is inserted vertically into the positioning groove 5, and the positioning groove 5 can limit the movement of the positioning member 3 in the horizontal direction, thereby positioning the positioning member 3 on the folding device. When the elastic member 4 needs to be replaced, pull out the positioning member 3 from the positioning groove 5, and the elastic member 4 can be replaced outside the folding device, which increases the operation space and makes the installation and disassembly of the elastic member 4 more convenient.
[0040] Further, the positioning member 3 has a long side wall 31 and two L-shaped short side walls 32. The two L-shaped short side walls 32 are arranged at both ends of the long side wall 31. The positioning groove 5 has two L-shaped grooves, and the shapes of the two L-shaped grooves match those of the two L-shaped short side walls 32. By inserting the two L-shaped short side walls 32 into the two L-shaped grooves one by one and making the two L-shaped short side walls 32 abut against the two L-shaped grooves, the positioning member 3 can be positioned in the positioning groove 5, avoiding the movement of the positioning member 3 in the horizontal direction and improving the use effect of the folding device. Optionally, in this embodiment, the positioning groove 5 further has a long groove, and the two L-shaped grooves are located at both ends of the long groove. The long side wall 31 on the positioning member 3 abuts against the long groove, making the positioning member 3 more stably arranged on the folding device, and the positioning groove 5 further restricts the movement of the positioning member 3 in the horizontal direction.
[0041] The cooperation mode between the positioning groove 5 and the positioning member 3 is not limited to this. It can also be that the positioning member 3 has a through hole, and the folding frame 1 has a positioning portion. The positioning portion is located in the positioning groove 5, and the through hole on the positioning member 3 is inserted into the positioning portion, and the peripheral wall of the positioning groove 5 abuts against the peripheral wall of the positioning member 3, thereby positioning the positioning member 3 on the folding device.
[0042] In this embodiment, the elastic member 4 is a compression spring. The two ends of the compression spring are fixedly arranged on the positioning member 3 and can apply a force along the axial direction of the spring to the stopper 2. Its performance is stable and the installation is convenient.
[0043] When folding the transparent paper of the cigarette pack, in order to reduce the stress of a single elastic member 4, the folding device is provided with a plurality of elastic members 4. The plurality of elastic members 4 are spaced apart along the horizontal direction. If a single elastic member 4 suffers from fatigue failure, the other elastic members 4 can also ensure the normal operation of the folding device, avoiding the phenomenon that the stopper 2 cannot rotate and reset due to the failure of the elastic member 4, resulting in the collision of the cigarette pack at the folding device and reducing the risk of production shutdown. In this embodiment, three elastic members 4 are provided, and the three elastic members 4 are spaced apart along the horizontal direction on the positioning member 3. This setting prolongs the service life of the elastic member 4.
[0044] As Figure 2 shown, a fixed shaft 6 is provided on the side wall of the accommodating cavity 11. The two ends of the fixed shaft 6 are rotatably arranged on the side wall of the accommodating cavity 11. A positioning hole 21 is provided on the stopper 2, and the fixed shaft 6 is rotatably inserted into the positioning hole 21, enabling the stopper 2 to rotate along the axis direction of the fixed shaft 6, so that the stopper 2 can enter or pop out of the accommodating cavity 11 of the folding frame 1 under the action of the elastic member 4.
[0045] After the cigarette pack passes through the folding device, the stop block 2 rotates and resets under the action of the elastic member 4. In order to limit the rotation angle of the stop block 2, the folding device further includes a limiting member 7. The limiting member 7 is arranged on the folding frame 1 and is located on the side of the stop block 2 away from the elastic member 4. When the stop block 2 rotates and resets, the side of the stop block 2 away from the elastic member 4 abuts against the limiting member 7, preventing the stop block 2 from rotating too much and completely popping out of the receiving cavity 11.
[0046] Further, as Figure 3 shown, a limiting portion 22 is provided on the stop block 2. When the stop block 2 rotates and resets, the limiting portion 22 abuts against the limiting member 7. In this embodiment, one end of the stop block 2 close to the limiting member 7 has a notch, and the limiting member 7 abuts against the inner wall of the notch, limiting the rotation angle of the stop block 2 when it rotates and resets.
[0047] One side of the stop block 2 away from the folding frame 1 has a flat surface and an inclined surface. The inclined surface is located at the lower end of the flat surface, and at least part of the flat surface protrudes from the opening of the receiving cavity 11 to the outside of the receiving cavity 11. When the cigarette pack passes through, the flat surface contacts the cigarette pack to fold the outer transparent paper of the cigarette pack. The inclined surface extends towards the inside of the receiving cavity 11. This setting avoids the lower end of the stop block 2 from obstructing the movement of the cigarette pack when the cigarette pack passes through the folding device from bottom to top.
[0048] Optionally, one end of the stop block 2 close to the bottom of the receiving cavity 11 is an arc surface, which avoids the bottom end of the stop block 2 contacting the bottom of the receiving cavity 11 when the stop block 2 rotates and scratching the receiving cavity 11.
[0049] An embodiment of the present invention also provides a packaging machine, which includes a packaging machine base and two folding devices. The two folding devices are symmetrically arranged on the packaging machine base along the conveying direction of the workpiece. By setting the folding device, the packaging machine avoids the risk of production downtime and improves the wrapping efficiency of the outer transparent paper of the cigarette pack.
[0050] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, and are not intended to limit the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
