Description

Technical Field

[0001] This invention relates to the field of cigarette packaging processing equipment technology, and in particular to a soldering iron heating device based on a GDX2 packaging machine. Background Technology

[0002] The GDX2 packaging machine is an important piece of equipment used for cigarette pack forming in cigarette production. The GDX2 unit has a total of eight rollers. Roller 1 is used to pack 20 qualified cigarettes into a mold box on roller 1. Then, roller 2 completes the aluminum foil packaging. Roller 3 folds the aluminum foil. Roller 4 completes the cardboard packaging. Roller 5 completes the label packaging. After passing through roller 6, the cigarette pack is transferred to roller 7 for heating and drying. Finally, the cigarette pack is sent to roller 8 for quality inspection. After passing the inspection, it is sent to the transparent paper packaging machine for packaging.

[0003] In existing technology, the No. 7 wheel typically includes thirty-six mold boxes and two disc supports. The thirty-six mold boxes are installed between the two disc supports, with a workstation for cigarette packs to enter between every two adjacent mold boxes. The heating and drying process of the cigarette packs in the No. 7 wheel mainly utilizes soldering irons located on the upper and lower sides of the No. 7 wheel. These two soldering irons can heat the two sides of the cigarette packs located on the No. 7 wheel, drying the adhesive dots between the label paper and the sides of the cigarette pack. In addition, to ensure that the No. 7 wheel can smoothly receive cigarette packs rotating from the No. 6 wheel, and the No. 8 wheel can smoothly receive cigarette packs rotating from the No. 7 wheel, the movement mode of the No. 7 wheel is usually set to rotate intermittently. Furthermore, to ensure that the upper and lower soldering irons can smoothly contact the sides of the cigarette pack, the lower soldering iron will also move upward during the pause time of the No. 7 wheel, so that the upper and lower soldering irons can fully contact the two sides of the cigarette pack. After the upper and lower soldering irons have made contact with the cigarette pack, they smoothly return to their original positions, and then the No. 7 wheel rotates again, thus repeating the cycle.

[0004] However, during the heating process on the side of the cigarette pack, the power source driving the rotation of wheel number seven and the power source driving the movement of the lower soldering iron are two independent power sources. Therefore, it often happens that wheel number seven starts to rotate before the lower soldering iron has returned to its original position. When the lower soldering iron has not returned to its original position, the cigarette pack is still pressed between the upper and lower soldering irons. Rotating wheel number seven at this time can easily damage the cigarette pack and reduce the quality of work. Furthermore, in actual production, the width of each station on wheel number seven is often greater than the width of the cigarette pack, resulting in poor stability of the cigarette pack as it rotates with wheel number seven. The cigarette pack is easily displaced by centrifugal force and may even be thrown off wheel number seven, which also greatly reduces the quality of work. Summary of the Invention

[0005] In view of this, the purpose of this invention is to provide a soldering iron heating device based on the GDX2 packaging machine, which solves the problem of low working quality when heating the side of the cigarette pack at position seven of the GDX2 packaging machine.

[0006] The present invention solves the above-mentioned technical problems through the following technical means:

[0007] A soldering iron heating device based on a GDX2 packaging machine includes a base, an upper soldering iron assembly, a lower soldering iron assembly, and a No. 7 wheel. Multiple fixing posts are fixed to the base. The upper soldering iron assembly is fixed to the top of the fixing posts. The lower soldering iron assembly is slidably connected to the fixing posts and located below the upper soldering iron assembly. The No. 7 wheel is rotatably mounted between the upper and lower soldering iron assemblies. A cam lifting assembly for intermittently raising the lower soldering iron assembly is installed on the bottom side of the lower soldering iron assembly. A gear transmission assembly for controlling the intermittent rotation of the No. 7 wheel is installed inside the No. 7 wheel. A motor is installed on the base to drive the cam lifting assembly and the gear transmission assembly. The raising of the lower soldering iron assembly and the rotation of the No. 7 wheel are not synchronized. A stabilizing component is also installed on the No. 7 wheel to prevent cigarette packs from being thrown out.

[0008] Furthermore, a rotating rod is fixed on the output shaft of the motor. The cam lifting assembly includes a turntable fixed on the rotating rod. Two symmetrically arranged first rollers are rotatably mounted on the upper side of the turntable. The top of the first rollers abuts against the lower soldering iron assembly. Two symmetrically arranged bosses are fixed on the bottom side of the lower soldering iron assembly. The bosses are located on the movement trajectory of the first rollers. The gear transmission assembly includes a mounting plate fixed on a fixed column. The mounting plate is located between the upper and lower soldering iron assemblies. A rotating ring is rotatably mounted on the outer ring of the mounting plate. The seventh wheel is fixed on the rotating ring. A ring rack is fixed on the rotating ring. A transmission gear is rotatably mounted on the mounting plate. The transmission gear meshes with the ring rack. The upper end of the rotating rod passes through the lower soldering iron assembly and the mounting plate and is fixed with an incomplete gear. The incomplete gear can mesh with the transmission gear, and the stroke of the incomplete gear meshing with the transmission gear is not synchronized with the stroke of the first rollers and the bosses.

[0009] Furthermore, the upper soldering iron assembly includes a soldering iron, a heating rod, a mounting shell, and a mounting bracket. The soldering iron, heating rod, and mounting shell are all fan-shaped structures. The heating rod is installed inside the soldering iron, and the soldering iron is installed inside the mounting shell. The bottom side of the mounting shell is open, and the bottom side of the soldering iron protrudes from the open end of the mounting shell. The mounting bracket is fixedly connected to the mounting shell, and the top of the fixing post is fixed to the mounting bracket. The lower soldering iron assembly has the same structure as the upper soldering iron assembly, and the lower soldering iron assembly is symmetrically arranged with the upper soldering iron assembly. The fixing post passes through the mounting bracket of the lower soldering iron assembly and is slidably connected to the mounting bracket. The boss is fixed on the bottom side of the mounting bracket of the lower soldering iron assembly.

[0010] Furthermore, a first spring is sleeved on the fixing rod, with the upper end of the first spring fixed to the bottom side of the mounting plate and the lower end of the first spring fixed to the top side of the lower soldering iron assembly mounting bracket.

[0011] Furthermore, the soldering iron heating device also includes a braking assembly, which includes a ring-shaped brake plate with brake pads fixed on it. The brake pads are in contact with the bottom side of the rotating ring. Multiple telescopic rods are fixed to the bottom side of the brake plate. The end of each telescopic rod away from the brake plate is fixed to the top side of the lower soldering iron assembly mounting bracket. A second spring is sleeved on each telescopic rod. The top end of the second spring is fixed to the bottom side of the brake plate, and the bottom end of the second spring is fixed to the top side of the lower soldering iron assembly mounting bracket.

[0012] Furthermore, the seventh wheel includes two disc supports and multiple mold boxes. All the mold boxes are fixed between the two disc supports in a circumferential array structure. A station for cigarette boxes to enter is provided between every two adjacent mold boxes, and the disc support located on the lower side is fixed on the rotating ring.

[0013] Furthermore, the stabilizing component includes a stop plate, multiple stabilizing plates, and multiple push rods. Each stabilizing plate and push rod corresponds to a mold box. The mold box has a groove on one side facing one of the adjacent workstations. The stabilizing plate is slidably installed in the groove. A third spring is installed between the stabilizing plate and the mold box. One side of the stabilizing plate can enter the adjacent workstation, and a first wedge block is fixed on the other side of the stabilizing plate. The push rod is slidably installed in the mold box. One end of the push rod has a second wedge block that matches the stop block. The other end of the push rod passes through the mold box and extends into the inner ring of the seventh wheel. The stop plate is located in the inner ring of the seventh wheel and is fixed on a fixed post. The end of the push rod away from the second wedge block abuts against the circumferential side wall of the stop plate. The stop plate has a missing section and a complete section. The missing section corresponds to the notch position of the upper soldering iron and the lower soldering iron. The distance of the missing section from the center of the stop plate is less than the distance of the complete section from the center of the stop plate. A transition section is provided between the missing section and the complete section.

[0014] Furthermore, the mold box has sliding grooves on both the upper and lower sides of the groove, and L-shaped plates are fixed at both the upper and lower ends of the stabilizing plate. One end of the L-shaped plate is slidably installed in the sliding groove on the same side as it. There are two third springs, which are located in the two sliding grooves respectively. One end of the third spring abuts against the L-shaped plate, and the other end of the third spring abuts against the inner wall of the sliding groove.

[0015] Furthermore, an annular plate is fixedly installed between the two disc supports, and the push rod passes through the annular plate and is slidably connected to the annular plate.

[0016] Furthermore, a mounting plate is fixed to the end of the push rod away from the second wedge block, and a fourth spring is sleeved on the push rod. One end of the fourth spring abuts against the mounting plate, and the other end of the fourth spring abuts against the annular plate. A second roller is rotatably mounted on the side of the mounting plate away from the fourth spring, and the second roller abuts against the circumferential side wall of the abutment plate.

[0017] The beneficial effects of this invention are:

[0018] 1. By setting up a cam lifting assembly, a gear transmission assembly, and other structures, the present invention enables the device to drive the lower soldering iron assembly to lift and drive the No. 7 wheel to rotate through a single power source. The lifting action of the lower soldering iron assembly and the rotation action of the No. 7 wheel are not synchronized, thus avoiding the situation where the No. 7 wheel starts to rotate before the lower soldering iron has been reset. This not only reduces the risk of damaging the cigarette pack, but also saves costs and energy.

[0019] 2. This invention uses the cooperation between the brake assembly and the cam lifting assembly to enable the entire brake assembly to rise together with the lower soldering iron assembly, thereby causing the brake pads to abut against the rotating ring, preventing the rotating ring and the No. 7 wheel from continuing to rotate due to inertia, and reducing the risk of spatial misalignment on the No. 7 wheel.

[0020] 3. The present invention sets a stabilizing component on the No. 7 wheel, so that after the cigarette pack enters between the upper and lower soldering irons with the No. 7 wheel, it can be stabilized in the No. 7 wheel position by the stabilizing plate, reducing the risk that the cigarette pack will be displaced or thrown out of the No. 7 wheel due to centrifugal force during the rotation of the No. 7 wheel.

[0021] 4. Through the cooperation of the cam lifting assembly, gear transmission assembly, brake assembly, and stabilizing assembly, this invention enables the device to heat the label paper on the side of the cigarette pack more smoothly, reducing the risk of damaging the cigarette pack and the cigarette pack being thrown out of the No. 7 wheel, and greatly improving the quality of work.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] like Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 8 As shown, a soldering iron heating device based on a GDX2 packaging machine according to the present invention includes a base 1, an upper soldering iron assembly 2, a lower soldering iron assembly 3, and a No. 7 wheel 4. Two fixing posts 11 are fixed on the base 1, and the upper soldering iron assembly 2 is fixed to the top of the two fixing posts 11. The lower soldering iron assembly 3 is slidably connected to the fixing posts 11 and located below the upper soldering iron assembly 2. The No. 7 wheel 4 is rotatably installed between the upper soldering iron assembly 2 and the lower soldering iron assembly 3. A cam lifting assembly 5 for intermittently lifting the lower soldering iron assembly 3 is installed on the bottom side of the lower soldering iron assembly 3. A gear transmission assembly 6 for controlling the intermittent rotation of the No. 7 wheel 4 is installed inside the No. 7 wheel 4. The base 1 has a mounting groove, in which a motor 12 is installed. The motor 12 is used to drive... The cam lifting assembly 5 and gear transmission assembly 6 operate, and the lifting of the lower soldering iron assembly 3 and the rotation of the seventh wheel 4 are asynchronous. A power source drives the lifting of the lower soldering iron assembly 3 and the rotation of the seventh wheel 4, ensuring that the lifting action of the lower soldering iron assembly 3 and the rotation action of the seventh wheel 4 are asynchronous. This avoids the situation where the seventh wheel 4 starts to rotate before the lower soldering iron assembly 3 has been reset, which not only reduces the risk of damaging the cigarette pack, but also provides a stabilizing assembly 8 on the seventh wheel 4 to prevent the cigarette pack from being thrown out. When the cigarette pack transitions from the sixth wheel to the seventh wheel 4, the stabilizing assembly 8 can stabilize the cigarette pack to a certain extent, reducing the risk of the cigarette pack being thrown out of the seventh wheel 4 and improving work quality.

[0036] like Figure 2 and Figure 3As shown, the upper soldering iron assembly 2 includes a soldering iron 21, a heating rod 22, a mounting shell 23, and a mounting bracket 24. The soldering iron 21, heating rod 22, and mounting shell 23 all have a fan-shaped annular structure. This fan-shaped annular structure provides an opening through which the cigarette pack can enter and exit. A fan-shaped groove 211 is provided on the upper side of the soldering iron 21. The heating rod 22 is installed in the fan-shaped groove 211 of the soldering iron 21, providing heat to the soldering iron 21. The soldering iron 21 is installed inside the mounting shell 23, which has an open bottom. The bottom of the soldering iron 21 protrudes from the open end of the mounting shell 23, allowing the soldering iron 21 to smoothly act on the upper side of the cigarette pack. The main body of the mounting bracket 24 is a circular plate, with multiple support plates integrally formed on the sides of the circular plate. All support plates... All plates are fixed to the top side of the mounting shell 23 by bolts. The mounting bracket 24 of the upper soldering iron assembly 2 is fixed to the top of the two fixing posts 11. The lower soldering iron assembly 3 has the same structure as the upper soldering iron assembly 2 and is symmetrically arranged with the upper soldering iron assembly 2. The mounting bracket 24 of the lower soldering iron assembly 3 has two first through holes. The two fixing posts 11 pass through the two first through holes respectively, and the mounting bracket 24 can slide horizontally relative to the fixing posts 11. The seventh wheel 4 is located between the upper soldering iron assembly 2 and the lower soldering iron assembly 3. The tobacco pack before heating can enter the seventh wheel 4 through the gap between the upper soldering iron assembly 2 and the lower soldering iron assembly 3. The heated tobacco pack can enter and transfer to the eighth wheel through the gap between the upper soldering iron assembly 2 and the lower soldering iron assembly 3.

[0037] like Figure 2 and Figure 4As shown, a rotating rod 13 is fixed on the output shaft of the motor 12. The cam lifting assembly 5 includes a turntable 51 fixed on the rotating rod 13. The turntable 51 is located between the lower soldering iron assembly 3 and the base 1. A support plate 52 is provided on the base 1. Two L-shaped support rods 53 are fixed between the support plate 52 and the base 1. The turntable 51 is rotatably mounted on the support plate 52. In addition, the center of the support plate 52 has a side through hole through which the rotating rod 13 passes. The support plate 52 supports the turntable 51. Two symmetrically arranged first rollers 54 are rotatably mounted on the upper side of the turntable 51. The tops of the two first rollers 54 abut against the mounting bracket 24 of the lower soldering iron assembly 3. Two symmetrically arranged bosses 55 are fixed on the bottom side of the mounting bracket 24 of the lower soldering iron assembly 3. The boss 55 is a fan-shaped annular boss 55. The lowest point of the boss 55 in the horizontal direction gradually decreases from both ends to the middle. The middle part of the boss 55 is also provided with a platform surface, which is parallel to the horizontal plane. The two ends of the boss 55 are at the same horizontal height as the bottom side of the mounting bracket 24 of the lower soldering iron assembly 3. That is, the two ends of the boss 55 are connected to the bottom side of the mounting bracket 24 of the lower soldering iron assembly 3. The boss 55 is located on the movement trajectory of the roller. When the motor 12 drives the rotating rod 13 to rotate, the first roller 54 and the boss 55 cooperate with each other to form a cam-like movement, which can lift the entire lower soldering iron assembly 3 upward, so that the upper and lower soldering irons 21 can completely contact the upper and lower sides of the cigarette pack on the seventh wheel 4.

[0038] like Figure 2 and Figure 5As shown, the gear transmission assembly 6 includes a mounting plate 61 fixed on two fixed posts 11. The mounting plate 61 is located between the upper soldering iron assembly 2 and the lower soldering iron assembly 3. A rotating ring 62 is rotatably mounted on the outer ring of the mounting plate 61. The rotating ring 62 is a ring-shaped plate. A No. 7 wheel 4 is fixed on the rotating ring 62, allowing the No. 7 wheel 4 to rotate relative to the mounting plate 61 along with the rotating ring 62. A ring rack 63 is fixed on the upper side of the rotating ring 62. The ring rack 63 is located in the inner ring of the No. 7 wheel 4 and does not contact the No. 7 wheel 4. A fixed shaft 64 is vertically fixed on the upper side of the mounting plate 61 at a position off-center. A transmission gear 65 is rotatably mounted on the fixed shaft 64. The transmission gear 65 meshes with the ring rack 63. The rotating rod 1 The upper end of 3 passes through the mounting plate 61 and the mounting bracket 24 of the lower soldering iron assembly 3, and is fixed with an incomplete gear 66. The incomplete gear 66 can mesh with the transmission gear 65. The travel of one revolution of the incomplete gear 66 is the distance between two adjacent cigarette packs. That is, when the incomplete gear 66 rotates one revolution, a cigarette pack that transitions from wheel 6 to wheel 7 4 can enter between the upper and lower soldering irons 21. The travel of the incomplete gear 66 meshing with the transmission gear 65 is not synchronized with the travel of the roller and the boss 55 contacting each other. That is, when the incomplete gear 66 and the transmission gear 65 mesh, the roller and the boss 55 will not contact each other, and when the roller and the boss 55 contact each other, the incomplete gear 66 and the transmission gear 65 will not mesh.

[0039] like Figure 2 As shown, in order to ensure that the lower soldering iron assembly 3 can be smoothly reset after being lifted, a first spring 14 is fitted on each fixing post 11. The lower end of the first spring 14 is fixed to the top side of the mounting bracket 24 of the lower soldering iron assembly 3, and the upper end of the first spring 14 is fixed to the bottom side of the mounting plate 61. Before the lower soldering iron assembly 3 is lifted, the first spring 14 is in a natural state. After the lower soldering iron assembly 3 is lifted, the first spring 14 is in a compressed state. The elastic force of the first spring 14 enables the lower soldering iron assembly 3 to be smoothly reset.

[0040] like Figure 6 and Figure 7As shown, the heating device of the soldering iron 21 also includes a brake assembly 7. Because after the incomplete gear 66 disengages from the transmission gear 65, due to the inertia of the object, the rotating ring 62 and the seventh wheel 4 may continue to rotate for a certain displacement, causing the spatial station 43 on the seventh wheel 4 to misalign. This prevents the cigarette pack on the sixth wheel from smoothly transferring to the seventh wheel 4, and also prevents the cigarette pack on the seventh wheel 4 from smoothly entering the eighth wheel, potentially causing a shutdown of the entire production line. The brake assembly 7 can control the seventh wheel 4 to stop rotating after the incomplete gear 66 and the transmission gear 65 disengage. The brake assembly 7 includes a ring-shaped brake plate 71, located below the rotating ring 62. A ring-shaped brake pad 72 is fixed to the upper side of the brake plate 71, and the brake pad 72 contacts the bottom side of the rotating ring 62. Five telescopic rods 73 are fixed, with the bottom ends of the telescopic rods 73 fixed to the support plate of the mounting bracket 24 of the lower soldering iron assembly 3. Each telescopic rod 73 is fitted with a second spring 74, the top end of the second spring 74 is fixed to the bottom side of the brake plate 71, and the bottom end of the second spring 74 is fixed to the support plate of the mounting bracket 24 of the lower soldering iron assembly 3. When the roller is not in contact with the boss 55, that is, when the incomplete gear 66 and the transmission gear 65 are engaged, the brake pad 72 only contacts the bottom side of the rotating ring 62, so that the rotating ring 62 and the seventh wheel 4 can rotate normally. When the roller just contacts the boss 55, that is, when the incomplete gear 66 and the transmission gear 65 are disengaged, the entire brake assembly 7 can rise together with the lower soldering iron assembly 3, so that the brake pad 72 presses tightly against the rotating ring 62, preventing the rotating ring 62 and the seventh wheel 4 from continuing to rotate due to inertia.

[0041] like Figure 8 As shown, in this embodiment, the seventh wheel 4 includes two disc supports 41 and thirty-six mold boxes 42. All the mold boxes 42 are fixed in a circular array structure between the two disc supports 41. A station 43 for cigarette boxes to enter is provided between every two adjacent mold boxes 42, and the disc support 41 located on the lower side is fixed on the outer ring of the rotating ring 62.

[0042] like Figure 8 , Figure 9 and Figure 10As shown, the stabilizing component 8 includes a backing plate 81, multiple stabilizing plates 82, and multiple push rods 83. Each stabilizing plate 82 and push rod 83 corresponds one-to-one with a mold box 42, that is, there are thirty-six stabilizing plates 82 and push rods 83. Each mold box 42 is equipped with one stabilizing plate 82 and one push rod 83. A groove 421 is provided on the side of the mold box 42 facing the left station 43. The stabilizing plate 82 is slidably installed in the groove 421. The stabilizing plate 82 is a square plate made of plastic. Slide grooves 422 are provided on the upper and lower sides of the groove 421 in the mold box 42. L-shaped plates 821 are fixed at both ends of the stabilizing plate 82. One end of the L-shaped plate 821 is slidably installed in the slide groove 422 on the same side. A third spring 84 is installed in each slide groove 422. One end of the third spring 84 abuts against the L-shaped plate 821, and the other end of the third spring 84 abuts against the inner wall of the slide groove 422.

[0043] like Figure 8 , Figure 9 and Figure 10 As shown, one side of the stabilizing plate 82 can enter the left-side workstation 43, thereby reducing the width of the workstation 43. This allows the cigarette packs in the workstation 43 to be tightly attached between the stabilizing plate 82 and another mold box 42, stabilizing the cigarette packs in the workstation 43 and reducing the risk of the cigarette packs shifting or being thrown out of the No. 7 wheel 4 due to centrifugal force during rotation. The other side of the stabilizing plate 82 is fixed with a first wedge block 822. The push rod 83 is slidably installed in the mold box 42. One end of the push rod 83 is integrally formed with a second wedge block 831 that matches the first wedge block 822. When the push rod 83 pushes the second wedge block 831 to abut against the second wedge block 831, the side of the stabilizing plate 82 away from the first wedge block 822 can enter the left-side workstation 43. The other end of the push rod 83 passes through the mold box 42 and extends into the inner ring of the No. 7 wheel 4.

[0044] like Figure 8 , Figure 9 and Figure 10As shown, the abutment plate 81 is located in the inner ring of the seventh wheel 4 and fixed to two fixed posts 11. The end of the push rod 83 away from the second wedge block 831 abuts against the circumferential side wall of the abutment plate 81. The abutment plate 81 is provided with a missing section 811 and a complete section 812. Both the missing section 811 and the complete section 812 are arc segments. The missing part corresponds to the notch position of the upper soldering iron 21 and the lower soldering iron 21, and the complete section 812 corresponds to the part of the soldering iron 21 in the upper soldering iron 21 and the lower soldering iron 21. The distance of the missing section 811 from the center of the abutment plate 81 is less than the distance of the complete section 812 from the center of the abutment plate 81, that is, the radius of the missing section 811 is less than the radius of the complete section 812. Furthermore, a transition section 813 is provided at the connection between the missing section 811 and the complete section 812. The transition section 813 is a smooth inclined surface. When the mold box 42 is in the missing section 811 position, the push rod 83 of the mold box 42 abuts against the missing section 811, and the stabilizing plate 82 inside the mold box 42 is located in the groove 421. The station 43 corresponding to this mold box 42 can normally receive the cigarette packs transitioning from the sixth wheel. When the seventh wheel 4 rotates, causing the mold box 42 to rotate from the missing section 811 to the complete section 812, the push rod 83 will move away from the center of the abutment plate 81. This causes the second wedge block 831 to abut against the second wedge block 831, pushing the stabilizing plate 82 out of the groove 421, thereby reducing the width of the station 43. This provides a certain degree of stability to the cigarette packs in the station 43. After the width is reduced, the width of the station 43 is equal to the width of the cigarette pack, which can both stabilize the cigarette packs and prevent them from being damaged.

[0045] like Figure 11 As shown, in order to enable the push rod 83 to be smoothly pushed when transitioning from the missing section 811 to the complete section 812, an annular plate 44 is fixedly installed between the two disc supports 41. The annular plate 44 is located in the inner ring of the two disc supports 41. The annular plate 44 does not contact the mold box 42. The push rod 83 passes through the annular plate 44 and is slidably connected to the annular plate 44. The annular plate 44 can support the push rod 83, making the process of pushing the push rod 83 smoother.

[0046] like Figure 8 and Figure 11As shown, in order to ensure that the push rod 83 can be smoothly reset when it is switched from the complete section 812 to the missing section 811, a mounting plate 832 is fixed to the end of the push rod 83 away from the second wedge block 831. A fourth spring 85 is sleeved on the push rod 83. One end of the fourth spring 85 abuts against the mounting plate 832, and the other end of the fourth spring 85 abuts against the annular plate 44. When the push rod 83 is switched from the complete section 812 to the missing section 811, the push rod 83 is subjected to the elastic force of the fourth spring 85 and can be smoothly reset. In addition, a second roller 833 is rotatably mounted on the side of the mounting plate 832 away from the fourth spring 85. The second roller 833 abuts against the circumferential side wall of the abutment plate 81. When the seventh wheel 4 rotates, the roller can roll against the abutment plate 81, thereby reducing the friction between the push rod 83 and the circumferential side wall of the abutment plate 81, so that the device can operate smoothly.
