Description

Technical Field

[0001] This invention relates to the field of cigarette packaging machine technology, and in particular to a belt conveyor device and a cigarette box packaging machine. Background Technology

[0002] During the cigarette box packaging process, before wrapping the cigarette box, the transparent paper supply device and the pull belt supply device simultaneously transport the pull belt and transparent paper and glue them together according to the set position before conveying them to the next process for packaging the cigarettes. Because the cigarette boxes are arranged at intervals, the pull belt is conveyed intermittently during the packaging process, causing the pull belt to cycle through four states: acceleration, constant speed, deceleration, and stopping. This results in large speed fluctuations of the pull belt during the packaging process. Due to the poor plasticity of the pull belt, it is easy to stretch or even break during the acceleration to constant speed process due to the slow start, and it is easy to loosen during the deceleration to stopping process due to the slow stopping, making the conveying of the pull belt unstable.

[0003] In existing technology, a belt reel is typically mounted on a frame, and a belt reel braking mechanism is installed on the frame. The belt reel braking mechanism is hinged to the frame. One end of the mechanism has a brake pad that abuts against the belt reel, and the other end has a belt guide roller. The belt extending from the reel passes the bottom of the guide roller and extends upwards. A spring connects the brake pad and the hinge point between the belt reel braking mechanism and the frame. The other end of the spring is fixedly connected to the frame. During packaging, the belt extends upwards... When the belt extending from the guide roller is pulled, the tension on the belt exerts an upward force on the guide roller, causing it to move vertically upward. At this time, the end with the brake pad moves vertically downward, disengaging from the belt roll. The belt then drives the belt roll to rotate. After the belt roll begins to rotate, the brake pad is in contact with the roll but does not brake it. The belt roll rotates around its axis due to the pull of the belt while being stopped by the frictional force of the brake pad. The belt will neither slack nor break. However, during the rotation of the belt roll, the brake pad comes into contact with the roll. Prolonged rotation leads to wear on the brake pad, causing the belt to loosen during packaging, which is detrimental to the smooth operation of the packaging process. Summary of the Invention

[0004] The purpose of this invention is to provide a belt conveyor and a cigarette box packaging machine that can avoid wear on rotating parts and magnetic control components caused by prolonged rotation of the belt shaft, reduce frictional wear of rotating parts during belt conveying, and improve the stability of belt conveying.

[0017] The driven member is movably connected to the mounting assembly, the adjusting member is capable of abutting against the first end of the driven member, and the second end of the driven member is provided with the clamping member.

[0018] Preferably, the pull belt shaft includes:

[0019] The rotating shaft body is rotatably connected to the mounting assembly, the rotating component is coaxially fixed to the rotating shaft body, and the belt reel is sleeved on the rotating shaft body.

[0020] An elastic element is fixedly installed on the rotating shaft body and is capable of abutting against the inner wall of the belt drum.

[0021] Preferably, the belt conveyor further includes:

[0022] A buffer assembly is movably connected to the mounting assembly, the pull strap passes through the buffer assembly, and the buffer assembly is swayable relative to the mounting assembly to cushion the pull strap.

[0023] Preferably, the buffer component includes:

[0032] Preferably, the auxiliary conveying component includes:

[0033] A drive unit, the drive unit being connected to the mounting assembly;

[0034] An auxiliary conveyor is provided, the first end of which is connected to the output end of the drive component. The drive component rotates, causing the auxiliary conveyor to rotate. The second end of the auxiliary conveyor is in frictional contact with the belt.

[0035] A cigarette box packaging machine includes a cigarette box packaging machine body and a belt conveyor as described above, wherein the belt conveyor is disposed on the cigarette box packaging machine body.

[0036] The beneficial effects of this invention are:

[0037] This invention provides a belt conveyor and a cigarette box packaging machine. The belt conveyor is used to convey belts, which are conveyed in close contact with transparent strips. It includes an installation assembly, a belt shaft, a magnetic control assembly, and a linkage assembly. The belt shaft is rotatably connected to the installation assembly, and a belt roll is coaxially fixed to the belt shaft. The magnetic control assembly includes a rotating component and a magnetic control component. The rotating component is coaxially fixed to the belt shaft, and the magnetic control component is movably connected to the installation assembly. The magnetic control component can move closer to or further away from the rotating component to change the rotational resistance of the belt shaft. The linkage assembly is movably connected to the installation assembly. A first guide component is provided at the first end of the linkage assembly, and a clamping component is provided at the second end of the linkage assembly. The belt can pass through the first guide component and drive the first guide component to move. The clamping component moves synchronously with the first guide component so that the clamping component abuts against the magnetic control component.

[0038] When the pull belt and transparent strip are initially conveyed, the pull belt extending from the first guide is pulled. The tension on the pull belt exerts a force on the first guide, causing it to move. Simultaneously, the clamping member at the second end of the adjusting assembly moves synchronously and abuts against the magnetic control. As the pull belt moves, the clamping member remains against the magnetic control, bringing the magnetic control closer to the rotating component. This increases the resistance of the magnetic control to the rotating component, thereby increasing the rotational resistance of the pull belt shaft, causing the pull belt conveyed from the pull belt drum to gradually tighten. When the pull belt and transparent strip are conveyed at a constant speed, the tension on the pull belt remains unchanged, and the distance between the magnetic control and the rotating component remains unchanged. When the pull belt and transparent strip are conveyed at a deceleration speed, the tension on the pull belt decreases, the clamping member adheres to the magnetic control, and the magnetic control moves relatively away from the rotating component. This reduces the resistance of the magnetic control to the rotating component, thereby reducing the rotational resistance of the pull belt shaft. In the above process, during the conveying process, the magnetic control and the rotating parts use a non-contact braking method to avoid wear on the rotating parts and magnetic control caused by the long-term rotation of the belt shaft, thereby reducing the friction and wear of the rotating parts during the belt conveying process and improving the stability of the belt conveying.

[0060] 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 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, and not all of the structures.

[0061] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0062] 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.

[0063] In the description of this embodiment, the terms "upper," "lower," "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 the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0064] This embodiment provides a belt conveyor device, such as... Figures 1-3 As shown, the belt conveyor is used to convey belts. The belts are conveyed in close contact with the transparent strip. It includes an installation assembly 1, a belt shaft 2, a magnetic control assembly 3, and a linkage assembly 4. The belt shaft 2 is rotatably connected to the installation assembly 1. A belt roll is coaxially fixed to the belt shaft 2. The magnetic control assembly 3 includes a rotating component 31 and a magnetic control component 32. The rotating component 31 is coaxially fixed to the belt shaft 2. The magnetic control component 32 is movably connected to the installation assembly 1. The magnetic control component 32 can move closer to or further away from the rotating component 31 to change the rotational resistance of the belt shaft 2. The linkage assembly 4 is movably connected to the installation assembly 1. A first guide component 51 is provided at the first end of the linkage assembly 4, and a clamping component 44 is provided at the second end of the linkage assembly 4. The belt can pass through the first guide component 51 and drive the first guide component 51 to move. The clamping component 44 moves synchronously with the first guide component 51 so that the clamping component 44 can abut against the magnetic control component 32.

[0065] When the pull belt and transparent strip are initially conveyed, the pull belt extending from the first guide member 51 is pulled. The tension on the pull belt exerts a force on the first guide member 51, causing it to move. Simultaneously, the clamping member 44 at the second end of the linkage component 4 moves synchronously and abuts against the magnetic control 32. As the pull belt moves, the clamping member 44 remains against the magnetic control 32, bringing the magnetic control 32 closer to the rotating member 31. This increases the resistance of the magnetic control 32 to the rotating member 31, thereby increasing the rotational resistance of the pull belt shaft 2, causing the pull belt conveyed from the pull belt drum to gradually tighten. When the pull belt and transparent strip are conveyed at a constant speed, the tension on the pull belt remains unchanged, and the distance between the magnetic control 32 and the rotating member 31 remains unchanged. When the pull belt and transparent strip are conveyed at a deceleration speed, the tension on the pull belt decreases, the clamping member 44 adheres to the magnetic control 32, and the magnetic control 32 moves relatively away from the rotating member 31. This reduces the resistance of the magnetic control 32 to the rotating member 31, thereby reducing the rotational resistance of the pull belt shaft 2. In the above process, during the conveying of the belt, the magnetic control 32 and the rotating component 31 use a non-contact braking method to avoid wear on the rotating component 31 and the magnetic control 32 caused by prolonged rotation of the belt shaft 2. This reduces frictional wear on the rotating component 31 during belt conveying and improves the stability of belt conveying. It should be noted that in this embodiment, the rotating component 31 is a disc structure. In other embodiments, the rotating component 31 can also be a ring structure or a cylindrical structure, etc. No limitation is made here. It should also be noted that in this embodiment, the magnetic control 32 is an arc-shaped structure. In other embodiments, the magnetic control 32 can also be a polygonal structure, etc. No limitation is made here.

[0066] Specifically, such as Figure 1 and Figure 2 As shown, in this embodiment, the linkage component 4 is positioned below the magnetic control component 3, and the pull strap passes through the bottom of the first guide member 51 and moves upward. In other embodiments, the linkage component 4 may also be positioned above the magnetic control component 3, and the pull strap passes through the top of the first guide member 51 and moves downward, etc. No limitations are imposed here.

[0067] Specifically, such as Figure 3 As shown, in this embodiment, the magnetic control 32 is slidably connected to the mounting component 1. In other embodiments, the magnetic control 32 may also be rotatably connected to the mounting component 1. No limitation is imposed here.

[0068] Specifically, such as Figure 1 and Figure 3 As shown, in this embodiment, the center of the magnetic control 32 and the center of the rotating member 31 are on the same straight line, and the magnetic control 32 can move closer to or away from the rotating member 31 along the direction of the center of the rotating member 31. The above arrangement ensures that the rotating member 31 can be uniformly stressed when the magnetic control 32 moves closer to or away from the rotating member 31.

[0069] Optionally, such as Figure 1 As shown, in this embodiment, the rotating member 31 includes a rotating body 311 and a first magnetic part 312. The first magnetic part 312 is disposed on the outer peripheral surface of the rotating body 311. The magnetic control unit 32 includes a magnetic control body 321 and a second magnetic part 322. The second magnetic part 322 is disposed on the side of the magnetic control body 321 facing the rotating body 311. The first magnetic part 312 and the second magnetic part 322 have opposite magnetic properties. Since the first magnetic part 312 and the second magnetic part 322 are oppositely disposed, when the rotating member 31 rotates relative to the magnetic control unit 32, the magnetic control unit 32 and the rotating member 31 attract each other, thereby providing non-contact resistance to the rotating member 31. It should be noted that in this embodiment, both the first magnetic part 312 and the second magnetic part 322 are magnets. In other embodiments, the first magnetic part 312 and the second magnetic part 322 can also be neodymium iron boron alloy or silicon steel sheet, etc. No limitations are imposed here.

[0070] Optionally, in this embodiment, multiple first magnetic parts 312 and multiple second magnetic parts 322 are provided. The multiple first magnetic parts 312 are evenly spaced along the circumferential direction of the rotating body 311 on its outer circumferential surface, and the multiple second magnetic parts 322 are evenly spaced along the circumferential direction of the magnetic control body 321 on the side of the magnetic control body 321 facing the rotating body 311. The evenly distributed multiple first magnetic parts 312 and second magnetic parts 322 make the magnetic field distribution more uniform, thereby making the force on the pull belt more uniform when braking the pull belt shaft 2, and making the braking process of the pull belt more stable.

[0071] Optionally, such as Figure 1 and Figure 4 As shown, in this embodiment, the rotating component 31 has multiple through holes 313, which are evenly distributed on the surface of the rotating body 311. The through holes 313 reduce the weight of the rotating component 31 and decrease its moment of inertia, while also facilitating airflow and heat dissipation. It should be noted that in this embodiment, six through holes 313 are provided. In other embodiments, three, four, or five through holes 313 may be provided, etc. This is not a limitation.

[0072] Optionally, such as Figure 1 and Figure 2 As shown, in this embodiment, the linkage component 4 is slidably connected to the mounting component 1. In other embodiments, the linkage component 4 may also be rotatably connected to the mounting component 1, etc. No limitations are imposed here.

[0073] Optionally, such as Figure 1 and Figure 2As shown, in this embodiment, the clamping member 44 is fixed to the second end of the linkage assembly 4, and the clamping member 44 is a clamping column. In other embodiments, the clamping member 44 can also be a clamping plate or a clamping rod, etc. No limitation is made here. It should be noted that in this embodiment, the clamping member 44 can abut against the side of the magnetic control body 321 away from the rotating body 311. In other embodiments, the clamping member 44 can also abut against any position of the magnetic control body 321, as long as it can drive the magnetic control body 321 closer to or further away from the rotating body 311.

[0074] Optionally, such as Figure 1 and Figure 2 As shown, the first guide member 51 is a guide roller. In other embodiments, the first guide member 51 may also be a structure with curved guide grooves or a guide wheel, etc. No limitation is made here.

[0075] Furthermore, such as Figure 3 As shown, the magnetic control assembly 3 also includes a limiting sleeve 34 and a first elastic element 33; wherein, the limiting sleeve 34 is fixedly connected to the mounting assembly 1, one end of the first elastic element 33 abuts against or is connected to the magnetic control component 32, and the other end of the first elastic element 33 abuts against or is connected to the limiting sleeve 34. When the magnetic control body 321 approaches the rotating body 311, the clamping member 44 abuts against the magnetic control body 321, so that the magnetic control body 321 overcomes the force of the first elastic element 33, increasing the rotational resistance to the rotating body 311; when the magnetic control body 321 moves away from the rotating body 311, the clamping member 44 adheres to the magnetic control body 321, and the first elastic element 33 gradually returns to its original state due to its elastic properties, thus reducing the rotational resistance to the rotating body 311. The above configuration is simple in structure and easy to maintain. It should be noted that in this embodiment, the first elastic element 33 is a spring. In other embodiments, the first elastic element 33 can also be a rubber shock absorber, etc. There are no limitations here.

[0076] Optionally, such as Figure 3 As shown, in this embodiment, the magnetic control assembly 3 further includes a connector 35. One end of the connector 35 is slidably connected to the limiting sleeve 34, and the other end of the connector 35 is fixedly connected to the side of the magnetic control component 32 facing the rotating component 31. The connector 35 and the limiting sleeve 34 cooperate to provide guidance for the sliding of the magnetic control component 32. In other embodiments, the other end of the connector 35 may also be fixedly connected to the side of the magnetic control component 32 away from the rotating component 31, or the other end of the connector 35 may be fixedly connected to the side wall of the magnetic control component 32. No limitation is imposed here, as long as the magnetic control component 32 and the connector 35 can be fixed. It should be noted that in this embodiment, the connector 35 is a square rod. In other embodiments, the connector 35 may also be a round rod, etc. No limitation is imposed here.

[0077] Specifically, such as Figure 3 As shown, in this embodiment, the other end of the connector 35 is welded to the side of the magnetic control body 321 facing the rotating body 311, resulting in a strong welded connection. In other embodiments, the other end of the connector 35 can also be bonded to the side of the magnetic control body 321 facing the rotating body 311 or integrally formed. No limitations are imposed here.

[0078] Specifically, in this embodiment, the first elastic element 33 is sleeved on the outer periphery of the connector 35. This provides sliding guidance for the magnetic control 32 while also preventing the first elastic element 33 from bending. In other embodiments, the first elastic elements 33 may also be arranged side-by-side on the side of the connector 35, etc. No limitations are imposed here.

[0079] Optionally, in this embodiment, one end of the first elastic member 33 abuts against the magnetic control 32, and the other end of the first elastic member 33 abuts against the limiting sleeve 34, and the first elastic member 33 is in a compressed state. In other embodiments, one end of the first elastic member 33 is connected to the magnetic control 32, and the other end of the first elastic member 33 is connected to the limiting sleeve 34, and the first elastic member 33 is in a stretched state or a normal state. No limitations are imposed here.

[0080] Optionally, such as Figure 3 As shown, in this embodiment, the magnetic control assembly 3 also includes a limiting member (not shown in the figure). The limiting member is fixedly connected to the mounting assembly 1. A limiting port is opened at the end of the connecting member 35 away from the magnetic control body 321. The limiting member passes through the limiting port and can slide within the limiting port. When the magnetic control body 321 gets infinitely close to the rotating body 311, the limiting member moves to one end of the limiting port. At this time, the magnetic control body 321 no longer moves relative to the rotating body 311, preventing the magnetic control body 321 from colliding with the rotating body 311 and causing the first magnetic part 312 or the second magnetic part 322 to interfere and fall off.

[0081] Furthermore, such as Figure 1 and Figure 2 As shown, the linkage component 4 includes a first swing member 41, an adjusting member 42, and a driven member 43; wherein, the first swing member 41 is rotatably connected to the mounting component 1, a first guide member 51 is provided at the first end of the first swing member 41, the adjusting member 42 is connected to the first swing member 41, the driven member 43 is movably connected to the mounting component 1, the adjusting member 42 can abut against the first end of the driven member 43, and a clamping member 44 is provided at the second end of the driven member 43.

[0082] When the conveyor belt is pulled, the belt extending from the first guide member 51 is pulled upwards. The tension on the belt exerts an upward force on the first guide member 51, causing it to move vertically upwards. Simultaneously, the first swing member 41 rotates, and the connected adjusting member 42 rotates at the same time, thereby causing the driven member 43 to move on the mounting assembly 1, so that the clamping member 44 abuts against the magnetic control body 321. The above arrangement provides a strong guarantee for the stable operation of the belt conveyor device and the precise adjustment during belt conveyor braking through the coordinated work of various components. It should be noted that in this embodiment, the adjusting member 42 is a cam plate structure. In other embodiments, the adjusting member 42 may also be a rectangular plate, one end of which is fixedly connected to the first swing member 41, and the second end of which is inclined toward one side of the first guide member 51, and the second end of which can abut against the first end of the driven member 43. Alternatively, the adjusting member 42 may also be a rhomboid plate, one apex of which is fixedly connected to the first swing member 41, and the opposite apex of which is inclined toward one side of the first guide member 51, and the opposite apex of which can abut against the first end of the driven member 43, etc. No limitation is imposed here.

[0083] Specifically, such as Figure 1 and Figure 2 As shown, in this embodiment, the adjusting member 42 includes an adjusting part and a connecting part. The adjusting part can abut and press against the first end of the driven member 43. One end of the connecting part is fixedly connected to the adjusting part, and the other end of the connecting part is fixedly and adjustablely connected to the first swing member 41. The above arrangement allows the position of the adjusting part relative to the first swing member 41 to be varied, thereby adjusting the contact time and contact point between the adjusting part and the driven member 43 when the first swing member 41 rotates. This changes the time when the magnetic control body 321 approaches or moves away from the rotating body 311, improving the versatility and applicability of the belt conveyor.

[0084] Optionally, such as Figure 1 and Figure 2 As shown, in this embodiment, the first swing member 41 is a swing connecting plate. In other embodiments, the first swing member 41 may also be a swing connecting rod, etc. No limitation is made here.

[0085] Optionally, such as Figure 1 and Figure 2As shown, in this embodiment, the linkage component 4 further includes a first counterweight 45, which is detachably connected to the second end of the first swing member 41. The first counterweight 45 allows the center of gravity of the first swing member 41 to be changed when it is pulling the conveyor belt, ensuring that the first swing member 41 remains balanced under different positions and forces, facilitating operation and control. Specifically, in this embodiment, multiple first counterweights 45 are provided, each detachably connected to the second end of the first swing member 41 to adjust the balance at both ends of the first swing member 41. It should be noted that the first counterweight 45 in this embodiment is a counterweight block, and the number of first counterweights 45 is not limited; it can be two, three, four, or more. No limitation is imposed here.

[0086] Specifically, in this embodiment, such as Figure 2 As shown, the pivot of the first swing member 41 can be located anywhere between the first counterweight 45 and the first guide member 51, without any limitation.

[0087] Optionally, such as Figure 2 As shown, in this embodiment, the mounting component 1 has a swing hole, the first swing member 41 has an adjustment hole 411, and the linkage component 4 also includes an adjustment rod. One end of the adjustment rod is fixedly and adjustablely connected to either the adjustment hole 411 or the swing hole, and the other end of the adjustment rod can slide in the other one. This configuration limits the swing amplitude of the first swing member 41. Specifically, in this embodiment, one end of the adjustment rod is fixedly and adjustablely connected to the adjustment hole 411, and the other end of the adjustment rod can slide in the swing hole. In other embodiments, one end of the adjustment rod is fixedly and adjustablely connected to the swing hole, and the other end of the adjustment rod can slide in the adjustment hole 411. No limitation is made here. It should be noted that in this embodiment, the adjustment hole 411 is an arc-shaped hole. In other embodiments, the adjustment hole 411 can also be a waist-shaped hole or a rectangular hole, etc. No limitation is made here.

[0088] Optionally, such as Figure 2 As shown, in this embodiment, the follower 43 is slidably connected to the mounting assembly 1. In other embodiments, the follower 43 may also be rotatably connected to the mounting assembly 1, etc. No limitation is made here.

[0089] Optionally, such as Figure 1 and Figure 2 As shown, in this embodiment, the driven member 43 is a driven plate. In other embodiments, the driven member 43 may also be a driven rod or a driven post, etc. No limitation is made here.

[0090] Optionally, such as Figure 2As shown, in this embodiment, a rolling part 431 is provided at the first end of the driven member 43, and the rolling part 431 can abut and press against the adjusting member 42. By providing the rolling part 431, the coordinated movement between the adjusting member 42 and the driven member 43 is flexible. It should be noted that in this embodiment, the rolling part 431 is rotatably connected to the first end of the driven member 43. The rotatable connection makes the coordinated movement between the rolling part 431 and the adjusting member 42 more flexible. Specifically, as... Figure 2 As shown, in this embodiment, the rolling part 431 is a rolling wheel. In other embodiments, the rolling part 431 may also be a rolling shaft, etc. No limitation is made here.

[0091] Furthermore, such as Figure 5 As shown, the belt conveyor shaft 2 includes a shaft body 21 and an elastic element 22. The shaft body 21 is rotatably connected to the mounting assembly 1, the rotating component 31 is coaxially fixed to the shaft body 21, the belt reel is sleeved outside the shaft body 21, and the elastic element 22 is fixedly mounted on the shaft body 21, abutting against the inner wall of the belt reel. The elastic element 22 ensures that the belt reel rotates synchronously with the shaft body 21 when the shaft body 21 rotates, preventing them from rotating at different speeds and improving the stability of the belt conveyor. It should be noted that in this embodiment, the elastic element 22 is a spring sheet. In other embodiments, the elastic element 22 can also be a disc spring, etc. No limitation is made here.

[0092] Specifically, such as Figure 5 As shown, in this embodiment, four elastic elements 22 are provided, and the four elastic elements 22 are evenly spaced along the axial direction of the rotating shaft body 21. In other embodiments, two, three, or five elastic elements 22 may also be provided, etc. There is no limitation here.

[0093] Optionally, such as Figure 5 As shown, in this embodiment, the belt conveyor shaft 2 further includes a fixing member 23, which is coaxially connected to the outer periphery of the shaft body 21, and one end of the fixing member 23 can abut against the belt roll. By setting the fixing member 23, the displacement of the belt roll in the axial direction is restricted, further ensuring the stability of the belt conveyor device.

[0094] Specifically, in this embodiment, the fastener 23 is a nut. In other embodiments, the fastener 23 may also be a clip, etc. No limitation is made here.

[0095] Furthermore, such as Figure 6As shown, the belt conveyor also includes a buffer assembly 6, which is movably connected to the mounting assembly 1. The belt passes through the buffer assembly 6, and the buffer assembly 6 can swing relative to the mounting assembly 1 to buffer the belt. During accelerated and constant-speed conveying, the belt passes through the buffer assembly 6, which is then subjected to force. The belt causes the buffer assembly 6 to swing, thereby releasing the belt. During decelerated conveying, the buffer assembly 6 swings in the opposite direction, buffering the belt between the belt drum and the buffer assembly 6, thereby relaxing the belt between the buffer assembly 6 and the belt drum. This configuration can mitigate the impact of intermittent motion during belt conveying on the belt quality and prevent the belt from being stretched or even broken.

[0096] Optionally, in this embodiment, the buffer assembly 6 is rotatably connected to the mounting assembly 1. In other embodiments, the buffer assembly 6 may also be slidably connected to the mounting assembly 1. No limitation is imposed here.

[0097] Furthermore, such as Figure 6 As shown, the buffer assembly 6 includes a buffer shaft 69, a second swing member 62, and a second guide member 64. The first end of the buffer shaft 69 is fixedly connected to the mounting assembly 1, the second end of the buffer shaft 69 is rotatably connected to the first guide member 61, the second swing member 62 is rotatably connected to the buffer shaft 69, and the second guide member 64 is rotatably connected to the second end of the second swing member 62. When conveying the belt, the belt passes sequentially through the first guide member 61 and the second guide member 64 before being conveyed in close contact with the transparent strip. During accelerated and constant-speed conveying, the force exerted by the belt on the second guide member 64 causes the second swing member 62 to swing in the same direction as the belt conveying, thereby releasing the belt. During decelerated conveying, the second swing member 62 swings in the opposite direction to the belt conveying due to gravity, thereby loosening the belt between the buffer assembly 6 and the belt reel. With this configuration, the buffer assembly 6 can store and absorb the belt through swinging, achieving belt swing buffering. It should be noted that in this embodiment, the first end of the buffer shaft 69 is welded to the mounting assembly 1. In other embodiments, the first end of the buffer shaft 69 may also be plugged into the mounting assembly 1, etc. No limitations are imposed here.

[0098] Specifically, in this embodiment, a bearing is provided between the second swing member 62 and the buffer shaft 69. The bearing can reduce the rotational friction between the second swing member 62 and the buffer shaft 69.

[0099] Specifically, such as Figure 6 As shown, in this embodiment, both the first guide 61 and the second guide 64 are guide rollers, and their structures are the same as those of the first guide 51. In other embodiments, the first guide 61 and the second guide 64 can also be guide wheels, etc. No limitations are imposed here.

[0100] Specifically, such as Figure 6 As shown, in this embodiment, the second swing member 62 is a bending plate. The bending plate enables the pull belt between the first guide member 61 and the second guide member 64 to form a Z-shape, increasing the wrap angle between the pull belt and the second guide member 64, reducing the possibility of slippage, and ensuring the stability and accuracy of the pull belt conveying. In other embodiments, the second swing member 62 can also be a bending block or a bending rod, etc. No limitation is made here.

[0101] Optionally, such as Figure 6 As shown, in this embodiment, a limiting hole 621 is formed at the first end of the second swing member 62. The buffer assembly 6 also includes a limiting member 63, which is movably connected to the mounting assembly 1. The limiting member 63 passes through the limiting hole 621 and can slide within it. The limiting hole 621 and the limiting member 63 allow the second swing member 62 to swing within a certain range, ensuring the smooth operation of the belt conveyor process. Simultaneously, the movable connection of the limiting member 63 to the mounting assembly 1 allows the swing range of the second swing member 62 to be adjusted, further improving the versatility of the belt conveyor device. It should be noted that in this embodiment, the limiting hole 621 is an arc-shaped hole. In other embodiments, the limiting hole 621 can also be a rectangular hole or an oblong hole, etc. No limitation is made here.

[0102] Furthermore, such as Figure 6 As shown, the buffer assembly 6 also includes a locking member 67 and a second elastic member 65. The locking member 67 is connected to the first end of the buffer shaft 69, and the second elastic member 65 is coaxially sleeved on the buffer shaft 69. One end of the second elastic member 65 abuts against the second swing member 62, and the other end abuts against the locking member 67. When the second swing member 62 swings around the buffer shaft 69, the presence of the second elastic member 65 provides a force opposite to the force exerted on the second swing member 62 by the belt, thus maintaining a stable state during conveying. This improves the stability of the belt conveyor. It should be noted that in this embodiment, the second elastic member 65 is a spring. In other embodiments, the second elastic member 65 can also be a rubber shock absorber or other elastic structure. No limitation is made here.

[0103] Specifically, such as Figure 6 As shown, in this embodiment, the locking member 67 is rotatably connected to the first end of the buffer shaft 69, and the locking member 67 is in contact with the mounting assembly 1. In other embodiments, the locking member 67 may also be fixedly connected to the first end of the buffer shaft 69, etc., and there are no limitations here.

[0104] Optionally, such as Figure 6As shown, in this embodiment, the buffer assembly 6 further includes a locking and limiting member 66, which includes a limiting part, a moving part, and a locking part. The limiting part is connected to the moving part, the moving part is slidably connected to the second end of the second swing member 62, and the locking part is elastically connected to the moving part and can be inserted into the second end of the second swing member 62.

[0105] During conveying, the pull belt passes through the second guide 64 and then the limiting part, and then is conveyed in contact with the transparent strip. The limiting part can move along the extension direction of the second swing member 62 on the second end of the second swing member 62 under the drive of the moving part. When the pull belt is placed into the second guide 64, the limiting part moves upward to limit the pull belt and prevent the pull belt from moving left or right or deviating from the second guide 64 due to jumping. When the limiting part reaches the upper limit position, the locking part is inserted into the second end of the second swing member 62 due to the elastic force to fix the movement of the limiting part.

[0106] Optionally, such as Figure 6 As shown, in this embodiment, the buffer assembly 6 further includes a handle 68, which is fixedly connected to the first end of the second swing member 62. The handle 68 facilitates manual installation of the pull strap and checking the flexibility of the second swing member 62.

[0107] Furthermore, such as Figure 8 As shown, the belt conveyor also includes an auxiliary conveying component 7, which is rotatably connected to the mounting component 1. The auxiliary conveying component 7 contacts the belt to convey it. By setting the auxiliary conveying component 7, not only is the conveying efficiency of the belt ensured, but also the problems of belt wear or conveying jams caused by improper speed are avoided.

[0108] Furthermore, such as Figure 8 As shown, the auxiliary conveying assembly 7 includes a driving component 71 and an auxiliary conveying component 73. The driving component 71 is connected to the mounting assembly 1, and the first end of the auxiliary conveying component 73 is connected to the output end of the driving component 71. Rotation of the driving component 71 drives the auxiliary conveying component 73 to rotate, and the second end of the auxiliary conveying component 73 makes frictional contact with the pull belt. This frictional contact drives the pull belt, ensuring synchronous transmission of the pull belt and the transparent strip. Optionally, in this embodiment, the surface of the second end of the auxiliary conveying component 73 that contacts the pull belt is provided with an anti-slip material. This increases the friction with the pull belt and improves the synchronicity of the pull belt transmission. It should be noted that the anti-slip material is rubber. In other embodiments, the anti-slip material can also be silicone, etc. No limitation is made here.

[0109] Specifically, such as Figure 8As shown, in this embodiment, the drive component 71 is a transparent conveyor roller. This ensures that the conveyor speed of the pull belt is the same as the conveyor speed of the transparent strip before the pull belt is conveyed to and bonded with the transparent strip, preventing the pull belt from becoming slack, stretched, or broken during conveying due to speed differences. In other embodiments, the drive component 71 can also be a separately installed rotary motor or rotary cylinder, etc. No limitations are imposed here.

[0110] Optionally, such as Figure 8 As shown, in this embodiment, the auxiliary conveying assembly 7 further includes a transmission component 72, which is coaxially connected to the output end of the drive component 71. The transmission component 72 is subjected to frictional transmission with the first end of the auxiliary conveying component 73. Specifically, in this embodiment, the transmission component 72 is a cylinder with a missing corner, and one rotation of the cylinder corresponds to the packaging process of one cigarette box. This saves material on the transmission component 72 during the conveyor belt pulling process. In other embodiments, the transmission component 72 can also be a complete cylinder or a disc, etc. No limitation is made here.

[0111] Optionally, such as Figure 8 As shown, in this embodiment, the auxiliary conveying assembly 7 further includes a sixth guide 74 and a seventh guide 75, which are located on both sides of the second end of the auxiliary conveyor 73 along the conveying direction of the belt. During the belt conveying process, the belt passes through the seventh guide 75, the auxiliary conveyor 73, and the sixth guide 74 in sequence, causing the belt to enter the second end of the auxiliary conveyor 73 at a certain angle, further increasing the friction between the belt and the second end of the auxiliary conveyor 73.

[0112] Optionally, such as Figure 1 , Figure 2 , Figure 7 and Figure 8As shown, in this embodiment, the belt conveyor further includes a guide assembly 5, which includes a first guide 51, a second guide 52, a third guide 53, a fourth guide 54, and a fifth guide 55. The first guide 51, second guide 52, and third guide 53 are all rotatably connected to the first swing member 41. Along the extending direction of the first swing member 41, the first guide 51, second guide 52, and third guide 53 are arranged at intervals, and the fourth guide 54 and fifth guide 55 are arranged at intervals, and are rotatably connected to the mounting assembly 1. During belt conveying, the belt wound on the belt reel passes sequentially through the third guide 53, fourth guide 54, second guide 52, fifth guide 55, and first guide 51, ultimately bonding with the transparent strip for transport. The multiple guides allow the belt to gradually change direction during transport, thus achieving belt conveying. It should be noted that in this embodiment, the first guide member 51, the second guide member 52, the third guide member 53, the fourth guide member 54, and the fifth guide member 55 are made of rigid plastic. This reduces the friction between the pull strap and the guide members. In other embodiments, the first guide member 51, the second guide member 52, the third guide member 53, the fourth guide member 54, and the fifth guide member 55 may also be made of ceramic, or the first guide member 51, the second guide member 52, and the third guide member 53 may be made of rigid plastic, while the fourth guide member 54 and the fifth guide member 55 may be made of ceramic, etc. No limitations are imposed here.

[0113] Specifically, in this embodiment, bearings are provided inside the first guide member 51, the second guide member 52, the third guide member 53, the fourth guide member 54, and the fifth guide member 55. This improves the flexibility of rotation.

[0114] Specifically, in this embodiment, the second guide member 52, the third guide member 53, the fourth guide member 54, and the fifth guide member 55 are all guide rollers. In other embodiments, the second guide member 52, the third guide member 53, the fourth guide member 54, and the fifth guide member 55 can also be guide wheels, or the second guide member 52 and the third guide member 53 can be guide rollers, and the fourth guide member 54 and the fifth guide member 55 can be guide wheels, etc. No limitations are imposed here.

[0115] Specifically, in this embodiment, such as Figure 2 and Figure 7As shown, along the extension direction of the first swing member 41, the first guide member 51, the second guide member 52, and the third guide member 53 are arranged sequentially, with the first guide member 51 located at the end of the first swing member 41. Along the axial direction of the first guide member 51, the lengths of the first guide member 51, the second guide member 52, and the third guide member 53 increase sequentially. During the conveying process, the lengths of the third guide member 53, the second guide member 52, and the first guide member 51 gradually decrease, which can restrict the movement of the conveying belt along the axial direction of the first guide member 51 during the conveying process, ultimately ensuring that the conveying belt is conveyed along the preset route.

[0116] Specifically, such as Figure 7 As shown, in this embodiment, the first guide member 51 includes a first guide body 511 and a first inclined portion 512. The first inclined portion 512 is fixedly connected to both ends of the first guide body 511, and the first inclined portion 512 is inclined towards the first guide body 511. This arrangement prevents the pull belt from falling off the first guide body 511 during the conveying process.

[0117] It should be noted that in this embodiment, the second guide member 52, the fourth guide member 54 and the fifth guide member 55 have the same structure as the first guide member 51, and will not be described again here.

[0118] Specifically, such as Figure 9 As shown, in this embodiment, the third guide member 53 includes a third guide body 531 and a second inclined portion 532. The second inclined portion 532 is fixedly connected to both ends of the third guide body 531, and the second inclined portion 532 is inclined towards the third guide body 531. This arrangement prevents the pull belt from falling off the third guide body 531 during the conveying process.

[0119] Specifically, such as Figure 9 As shown, in this embodiment, at least one end of the third guide member 53 has a protruding rod along the axial direction of the third guide body 531. The third guide member 53 also includes a third elastic member 533 and a sliding sleeve 534. The sliding sleeve 534 is sleeved on the protruding rod and is fixed to the mounting assembly 1. The third elastic member 533 is sleeved on the protruding rod, with one end abutting against the sliding sleeve 534 and the other end abutting against the third guide body 531. When the pull belt deviates, the third guide body 531 will move together with the pull belt to prevent the pull belt from deviating excessively and falling off. It should be noted that in this embodiment, the third elastic member 533 is provided on both sides of the sliding sleeve 534 along the axial direction of the third guide body 531. It should also be noted that the third elastic member 533 is a spring.

[0120] Specifically, in this embodiment, one end of the third guide member 53 has a protruding rod extending along the axial direction of the third guide body 531. In other embodiments, both ends of the third guide member 53 have protruding rods extending along the axial direction of the third guide body 531. No limitation is imposed here.

[0121] Optionally, such as Figure 8 As shown, in this embodiment, the belt conveyor further includes a first deflector 91 and a second deflector 92. Both the first deflector 91 and the second deflector 92 are rotatably connected to the mounting assembly 1, and can change the conveying direction of the belt. The arrangement of the first deflector 91 and the second deflector 92 ensures that the conveying direction of the belt is parallel to the conveying direction of the transparent strip, facilitating the close-fitting conveying of the belt and the transparent strip. It should be noted that in this embodiment, both the first deflector 91 and the second deflector 92 are guide rollers. In other embodiments, the first deflector 91 and the second deflector 92 can also be guide rollers, etc. No limitation is made here.

[0122] Optionally, such as Figure 8 As shown, in this embodiment, the fifth guide member 55 includes a fifth guide body 551, a fifth elastic member 552, and a buffer sleeve 553. The fifth guide body 551 is rotatably connected to the buffer sleeve 553, and the buffer sleeve 553 is slidably connected to the mounting assembly 1. One end of the fifth elastic member 552 is fixedly connected to the buffer sleeve 553, and the other end is fixedly connected to the mounting assembly 1. The fifth guide body 551 can rotate freely and also move up and down along the mounting assembly 1. When the belt is too tight, the fifth guide body 551 is buffered by the fifth elastic member 552, thereby releasing the belt. It should be noted that the third elastic member 533 is a spring.

[0123] Optionally, such as Figure 11 As shown, in this embodiment, the belt conveyor also includes a belt breakage detection component 8. The belt breakage detection component 8 is located before the belt is conveyed to the transparent strip. The belt breakage detection component 8 is used to detect whether the belt is broken.

[0124] Specifically, in this embodiment, the tape breakage detection component 8 includes a tape contact head 81, a detector 82, a detection head 83, a linkage rod 84, and a fixing rod 85; wherein, the fixing rod 85 is fixedly connected to the mounting component 1, the linkage rod 84 is rotatably connected to the fixing rod 85, one end of the linkage rod 84 is provided with a tape contact head 81, the tape contact head 81 can overlap the tape, the linkage rod 84 is connected to the detection head 83, and the detector 82 is set at a relative position to the detection head 83.

[0125] The pull cord contact head 81 is pressed against the pull cord under the action of gravity, maintaining a certain height. Changes in height alter the position of the detection head 83. The set value of the detector 82 can be adjusted according to the position of the detection head 83 and the detector 82. When the height decreases, causing the value to exceed the limit, a pull cord breakage signal is emitted, triggering a shutdown message and issuing a warning signal. This setup prevents sudden equipment shutdown. It should be noted that in this embodiment, the detector 82 is a capacitive detector. In other embodiments, the detector 82 can also be a resistive detector or an ultrasonic detector, etc. No limitation is made here.

[0126] Optionally, in this embodiment, a second counterweight 86 is provided at the other end of the linkage rod 84. The second counterweight 86 can move along the extension direction of the linkage rod 84. The second counterweight 86 can adjust the pressure between the pull belt contact head 81 and the pull belt, preventing the pull belt contact head 81 from jumping due to the up-and-down fluctuation of the pull belt when the pressure is too tight.

[0127] Specifically, in this embodiment, the second counterweight 86 has a fixing hole, and the belt conveyor includes a fastener (not shown in the figure), which passes through the fixing hole and is fixed to the linkage rod 84. In this embodiment, the fastener is a screw. In other embodiments, the fastener may also be a bolt, etc. No limitation is made here.

[0128] Optionally, in this embodiment, the belt conveyor further includes an offset detection component (not shown in the figure). The offset detection component is located before the belt is conveyed to the transparent strip. The offset detection component is used to detect the degree of offset between the actual conveying path of the belt and the preset conveying path. If the actual conveying path of the belt deviates too much from the preset conveying path, the belt conveyor stops. It should be noted that the offset detection component is prior art. In this embodiment, any offset detection component in the prior art can be used to detect the degree of offset between the actual conveying path of the belt and the preset conveying path. No further limitation is imposed here.

[0129] Optionally, in this embodiment, the belt conveyor further includes a belt presence detection component, which is positioned after the guide component 5. The belt presence detection component is used to detect the presence of the belt. The belt detection component is prior art, and in this embodiment, any prior art belt presence detection component can be used to detect the presence of the belt. Further details will not be provided here.

[0130] This embodiment also provides a cigarette box packaging machine, including a cigarette box packaging machine body and a belt conveyor device, which is installed on the cigarette box packaging machine body. By applying the belt conveyor device, wear between the rotating part 31 and the magnetic control 32 caused by the long-term rotation of the belt shaft 2 is avoided, frictional wear during belt conveying is reduced, and the stability of belt conveying is improved.

[0131] The following describes the belt conveyor path of the conveyor device:

[0132] The pull belt is drawn out from the pull belt spool sleeved on the rotating shaft body 21, and then passes through the third guide 53, the fourth guide 54, the second guide 52, the fifth guide 55 and the first guide 51 in sequence before passing through the pull belt presence detection component. After that, it passes through the seventh guide 75, the auxiliary conveyor 73 and the sixth guide 74 before passing through the first deflector 91 and the second deflector 92, so that the conveying direction of the pull belt is parallel to the conveying direction of the transparent strip. After passing through the first guide 61, the second guide 64 and the limiting part, it enters the offset detection component, which determines the conveying path of the pull belt just before it is about to be conveyed to the transparent strip. Finally, the pull belt is conveyed to the transparent strip.

[0133] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. 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 the present invention should be included within the scope of protection of the claims of the present invention.
