[0001] The utility model relates to the technical field of range hood equipment, in particular to a diameter adjustment device for a semiconductor chip refrigeration sealer of a filter rod forming machine. Background Art

[0002] The filter rod forming machine is a device used to produce cigarette filter rods. The sealer is the component used to wrap the tow with forming paper and then solidify the glue line on the paper. The tow is rolled into a round shape by a pipe gun and then wrapped with forming paper coated with sealing glue to form the filter rod. The sealing glue is hot melt glue. The sealing glue on the forming paper quickly solidifies under the cooling of the sealer, forming a filter rod with the required diameter.

[0003] During production, the filter rod forming machine requires real-time adjustment of the gap between the sealer and the base of the cigarette holder—in other words, the diameter of the filter rod—to ensure that the diameter meets standard requirements. In the prior art, the diameter adjustment of the semiconductor cooling sealer in the filter rod forming machine is controlled by a pulley drive. By rotating a motor, the belt drives a deflection wheel to control the gap between the sealer and the filter rod, thereby adjusting the filter rod diameter.

[0004] However, the belt is located inside the sealer, and the workload of disassembling the sealer to replace the belt is large. If the existing equipment is modified, the sealer has a complex structure and many parts, and a large amount of disassembly and modification will waste time and reduce production efficiency.

[0042] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0043] The diameter adjustment device of the semiconductor chip refrigeration sealer of the filter rod forming machine provided in this embodiment is used to adjust the gap 3 of the sealer, thereby adjusting the consistency of the filter rod diameter.

[0044] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 As shown, a specific embodiment of the diameter adjustment device of the semiconductor chip refrigeration sealer of the filter rod forming machine provided in this embodiment includes: a base plate 1, a cigarette gun base plate 15 and a sealer body 2; wherein, the cigarette gun base plate 15 is fixed to the base plate 1 by a set screw, the sealer is located above the cigarette gun base plate 15, and a gap 3 is provided between the sealer and the cigarette gun base plate 15. 2 The sealer body 2 is mounted on the vertical plate 13, and the support member 5 of the driving device abuts against the upper end surface of the base plate 1. The driving device drives the support member 5 to move with the base as the support, so that the sealer body 2 and the vertical plate 13 swing around the lower end surface of the vertical plate 13, thereby changing the distance between the sealer body 2 and the cigarette gun base plate 15. The diameter of each filter rod produced is within the production standard range.

[0045] Specifically, the upper end surface of the base plate 1 is provided with a mounting groove for accommodating the cigarette gun base plate 15 , and the cigarette gun base plate 15 is arranged in the mounting groove.

[0046] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, in this embodiment, the end surface of the vertical plate 13 facing the sealer body 2 is provided with a support shaft 12, and the sealer body 2 is provided with a support shaft 12 hole. The support shaft 12 passes through the support shaft 12 hole of the sealer body 2 and is connected to the driving device. The sealer body 2 is provided with a support shaft 12 hole; the support member 5 of the driving device is provided on the front side of the sealer body 2; the vertical plate 13 is provided on the rear side of the sealer body 2, and the lower end of the vertical plate 13 is rotatably connected to the bottom plate 1. Figure 8 As shown, the front side refers to the side of the base plate 1 facing the gap 3 in the width direction; the rear side refers to the side of the base plate 1 facing away from the gap 3 in the width direction. In other words, the support member 5 and the vertical plate 13 of the driving device are arranged relative to each other on the front and rear sides of the sealer body 2. The end surface of the vertical plate 13 facing the sealer body 2 is provided with a horizontally extending support shaft 12. The support shaft 12 passes through the support shaft 12 hole of the sealer body 2 and is connected to the driving end of the driving device. By providing the support shaft 12 on the vertical plate 13, the axial end of the support shaft 12 is connected to the driving device. The support member 5 of the driving device is supported by the upper end surface of the base, driving the end of the support shaft 12 to move in the vertical direction, thereby causing the vertical plate 13 to swing. It should be noted that the description in the above scheme is not restrictive. As an alternative embodiment, the support shaft 12 and the support shaft 12 hole can also be omitted. The driving device is a cylinder, and the driving end of the cylinder is fixedly connected to the support member 5. The cylinder drives the support member 5 to reciprocate, driving the vertical plate 13 to swing.

[0047] Specifically, after the support shaft 12 hole of the sealer body 2 passes through the support shaft 12 on the vertical plate 13, one side end surface of the sealer body 2 is attached to the side end surface of the vertical plate 13, and a bolt is used to pass through the vertical plate 13 from the side away from the sealer body 2 and then be threadedly connected to the outer shell of the sealer body 2, thereby fixing the sealer body 2 to the vertical plate 13.

[0048] Specifically, the vertical plate 13 and the support shaft 12 are integrally formed. The support shaft 12 passes through the sealer body 2 and is connected to the swing arm 4. During the adjustment process, the force applied by the driving device is transmitted to the vertical plate 13 by the support shaft 12, and the sealer body 2 is not subjected to force during this adjustment process. Two support shafts 12 are symmetrically arranged on the vertical plate 13 along the length of the vertical plate 13.

[0049] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4As shown, in this embodiment, the driving device includes: a driving assembly; a swing arm 4 is arranged in front of the sealer body 2, the first end of the swing arm 4 is hinged on the support shaft 12, and the second end of the swing arm 4 is connected to the driving assembly; a support member 5 is provided on the swing arm 4, one end of which is abutted against the upper end surface of the bottom plate 1; the support member 5 of the swing arm 4 is abutted against the bottom plate 1 as a fulcrum, and the driving end of the driving assembly is connected to the second end of the swing arm 4. When the driving assembly drives the second end of the swing arm 4 to move, the swing arm 4 rotates around the first end, thereby lifting or lowering the sealer body 2, so that the gap 3 becomes larger or smaller. The drive assembly is used to drive the swing arm 4 to rotate, causing the support shaft 12, the vertical plate 13, and the sealer body 2 to rotate about the rotation point of the vertical plate 13, thereby raising or lowering the sealer body 2, thereby adjusting the gap 3 between the sealer and the cigarette gun base plate 15. The first end of the swing arm 4 is hinged to the support shaft 12, and the second end of the swing arm 4 is connected to the drive assembly. The swing arm 4 is provided with a support member 5, one end of which abuts the upper end surface of the base plate 1. When the drive assembly drives the second end of the swing arm 4 to move downward in the vertical direction, the sealer body 2 is raised, thereby increasing the gap 3. Conversely, when the second end of the swing arm 4 moves upward, the sealer body 2 is lowered, thereby decreasing the gap 3. It should be noted that the description in the above scheme is not restrictive. As an alternative embodiment, the drive device can also be: a cylinder, the drive end of the cylinder is rotatably connected to the rotating shaft, the end of the cylinder is fixed to the base plate 1, and the swing arm 4 is driven by the cylinder to move.

[0050] The swing arm 4 is rotatably mounted on the outside of the sealer body 2. The swing arm 4 is hinged on the support shaft 12. The support member 5 serves as the fulcrum for the swing arm 4 to rotate. The drive assembly drives the second end of the swing arm 4 to move, so that the swing arm 4 rotates with the contact between the support member 5 and the bottom plate 1 as the fulcrum. When the swing arm 4 rotates around the first end, it raises or lowers the sealer body 2, making the gap 3 larger or smaller. This ensures the consistency of the filter rod diameter. Figure 1 、 Figure 2 、 Figure 3 As shown, in this embodiment, the swing arm 4 is provided with a limit member 6, which passes through the first end of the swing arm 4 and is threadedly connected to the support shaft 12. In addition, as an alternative embodiment, the limit member 6 can also be provided on the sealer body 2.

[0051] like Figure 1 、 Figure 2 、 Figure 3As shown, in this embodiment, the limiter 6 is provided at the axial end of the support shaft 12. The limiter 6 passes through the swing arm 4 and is threadedly connected to the support shaft 12. The limiter 6 comprises: a cylinder, one axial end of the cylinder is provided with a threaded column, and the other axial end is provided with an annular flange with a diameter larger than the diameter of the cylinder. The threaded column of the limiter 6 passes through the swing arm 4 and is threadedly connected to the threaded hole at the end of the support shaft 12. At this time, the swing arm 4 swings on the cylinder, and the annular flange is used to limit the axial position of the swing arm 4. At the same time, after removing the limiter 6, the swing arm 4 can be disassembled from the vertical plate 13. The threaded connection between the vertical plate 13 and the shell of the sealer body 2 can be removed, and the sealer body 2 can be removed from the vertical plate 13. Afterwards, a semiconductor refrigeration sealer or a cooling water sealer can be selected according to actual needs. The positions of the support shaft 12 holes on the semiconductor refrigeration sealer or the cooling water sealer are exactly the same, and they are easy to replace with each other without changing other parts. At the same time, the beat adjustment amount of the drive device is also exactly the same as that of the cooling water sealer, and there is no need to change the diameter control system when replacing them. In addition, as an alternative embodiment, the limiter 6 can be set as a bolt. In addition, as an alternative embodiment, the swing arm 4 can also be rotatably set on the support shaft 12, and the limiter 6 is set at the axial end of the support shaft 12 to limit the swing arm 4.

[0052] Specifically, a support shaft 12 hole is opened on the radiator of the semiconductor refrigeration sealer for passing the support shaft 12. By arranging the support shaft 12 hole on the semiconductor refrigeration radiator, the beat adjustment amount of the driving device is consistent with the existing equipment.

[0053] like Figure 4 As shown, in this embodiment, the support member 5 is threadedly connected to the swing arm 4 and positioned near the first end. The support member 5 passes through the upper end of the swing arm 4 and then exits the lower end of the swing arm 4. The lower end of the support member 5 abuts the base plate 1, serving as a fulcrum for rotation. By tightening the support member 5, the vertical plate 13 is maintained in a vertical position during initial adjustment. Alternatively, the support member 5 can be fixedly connected to the swing arm 4.

[0054] like Figure 2As shown, in this embodiment, an elastic member 7 is provided between the swing arm 4 and the sealer body 2. The elastic member 7 is disposed on the swing arm 4. The elastic member 7 is a tension spring, one end of which is connected to the swing arm 4 and the other end to the cross arm 8. Because the support member 5 is positioned near the first end, when the second end of the swing arm 4 moves upward, the tension spring generates a tension force that causes the second end of the swing arm 4 to rotate upward, causing the upper surface 11 of the swing arm to contact the surface of the rotating cam 10. Alternatively, as an alternative embodiment, the elastic member 7 can be omitted, and the height of the sealer body 2 can also be lowered by relying on the weight of the sealer body 2. Alternatively, as an alternative embodiment, the elastic member 7 can be configured as a spring, one end of which is connected to the lower end surface of the swing arm 4 and the other end is connected to the sealer body 2. Alternatively, as an alternative embodiment, the elastic member 7 can be configured as a torsion spring, one end of which is connected to the sealer body 2 and the other end is connected to the lower end surface of the swing arm 4.

[0055] like Figure 2 As shown, in this embodiment, the cross arm 8 is disposed in front of the sealer body 2, with a gap left between the cross arm 8 and the sealer body 2 to allow the swing arm 4 to rotate. This allows the swing arm 4 to be disposed between the cross arm 8 and the sealer body 2, thereby preventing interference between the swing arm 4 and the shield when the shield is installed on the sealer device. Alternatively, as an alternative embodiment, the cross arm 8 may be disposed only above the elastic member 7, without restricting the swing arm 4 and without affecting its rotation.

[0056] like Figure 6 、 Figure 8 As shown, in this embodiment, the driving assembly includes: a driving member 9 and a rotating cam 10. The driving member 9 is a stepping motor, and the driving end of the motor is connected to the rotating cam 10, and the rotating cam 10 abuts against the end face of the upper plane 11 of the swing arm 4. When the driving member 9 drives the rotating cam 10 to rotate, the upper plane 11 of the swing arm 4 always abuts against the rotating cam 10. When the rotating cam 10 rotates, the upper plane 11 of the swing arm 4 moves up and down, thereby driving the support shaft 12, the vertical plate 13 and the sealer body 2 to rotate around the rotation point of the vertical plate 13. In addition, as an alternative embodiment, the driving assembly can also be set as a cylinder, the cylinder is set in the vertical direction, the driving end of the cylinder is rotatably connected to the second end of the swing arm 4, and when the cylinder drives the second end of the swing arm 4 to move in the vertical direction, the swing arm 4 rotates with the support member 5 as the fulcrum.

[0057] like Figure 8As shown, in this embodiment, the apparatus further includes a reducer 14, the input end of which is connected to the drive end of the driver 9, and the output end of which is connected to the rotating cam 10. The reducer 14 can reduce the motor speed, thereby improving the adjustment accuracy, while also increasing the torque, thereby precisely controlling the size of the gap 3 in the sealer body 2. Alternatively, as an alternative embodiment, the reducer 14 can be omitted, and the driver 9 can be configured as a servo motor, which can also achieve precise control of the rotating cam 10.

[0058] Specifically, such as Figure 7 As shown, the second end of the swing arm 4 is provided with a swing arm upper plane 11 extending in the horizontal direction. The thickness of the swing arm upper plane 11 in the horizontal direction is less than the thickness of the swing arm 4 in the horizontal direction, so that when the two swing arms 4 are symmetrically arranged, the facades of the two swing arms 4 are on the same vertical plane. The two swing arms 4 are both attached to the side end faces of the sealer body 2 for rotation, and the rotating cam 10 of the driving member 9 abuts against the upper end faces of the two swing arm upper planes 11, so that the two swing arms 4 do not affect each other's rotation when rotating. In addition, as an alternative embodiment, the swing arm upper plane 11 can also be omitted, and the two swing arms 4 can be staggered to avoid conflict during rotation. In addition, as an alternative embodiment, the thickness of the abutment can also be set to be consistent with the thickness of the swing arm 4. In this case, the two swing arms 4 can be staggered.

[0059] The installation method of the diameter adjustment device of the semiconductor chip refrigeration sealer of the filter rod forming machine is as follows: it includes: the sealer body 2, the swing arm 4, the driving member 9, the rotating cam 10 and the elastic member 7. The bottom plate 1 is fixedly arranged horizontally, and the sealer body 2 is spaced apart above the bottom plate 15 of the cigarette gun. The swing arm 4 is arranged at the front of the sealer and fixed to the vertical plate 13 at the rear. There are two swing arms 4 symmetrically arranged, and the vertical plate 13 is rotatably connected to the bottom plate 1. The support shaft 12 on the vertical plate 13 passes through the sealer body 2 and is connected to the swing arm 4. The limit member 6 is threadedly connected to the support shaft 12. The first end of the swing arm 4 is hinged to the support shaft 12, so that the swing arm 4 can rotate with the support shaft 12 as the center of the circle. A support member 5 is provided near the first end of the swing arm 4. The support member 5 passes through the upper end surface of the swing arm 4 and exits from the lower end surface. After exiting, it abuts against the bottom plate 1. The elastic member 7 is arranged on the upper end surface of the swing arm 4 and is connected to the cross arm 8 of the sealer body 2. A horizontal upper surface 11 is provided at the second end of the swing arm 4. A rotating cam 10 is provided above the upper surface 11. The rotating cam 10 abuts against the upper surface 11, and the driving member 9 is connected to the rotating cam 10. The driving member 9 drives the rotating cam 10 to rotate, and the swing arm 4 drives the support shaft 12, the vertical plate 13, and the sealer body 2 to rotate about the rotation point of the vertical plate 13, thereby changing the gap 3 between the sealer body 2 and the bottom plate 15 of the cigarette gun.

[0060] The working principle of the diameter adjustment device for a semiconductor chip refrigeration sealer for a filter rod forming machine is as follows: the sealer body 2 is fixed to a vertical plate 13, which is fixed to the base via a rotating shaft. A stepper motor and reducer 14 are mounted on the upper end surface of the vertical plate 13. A rotating cam 10 is mounted on the output shaft of the reducer 14. A support shaft 12 is fixed to the vertical plate 13. One end of the swing arm 4 is hinged to the support shaft 12 and can swing around it. An elastic member 7 is connected to the swing arm 4 at one end and fixed to the cross arm 8 at the other end, ensuring that the upper surface of the swing arm 4 is always in contact with the curved surface of the rotating cam 10. When the cam rotates, it drives the swing arm 4 to rotate. The swing arm 4 is also mounted with a support member 5, the bottom end of which is supported by the base of the cigarette holder. During operation, the control system drives the stepper motor to rotate the rotating cam 10 through the reduction device according to the change in the diameter of the filter rod, and then drives the swing arm 4 to swing. Since the support member 5 is supported on the base of the cigarette gun, the vertical plate 13 and all the parts on it rotate around the rotating shaft through the lever principle, thereby adjusting the gap 3 between the sealer and the cigarette gun to achieve the purpose of adjusting the diameter.

[0061] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
