Description

Technical Field

[0001] This utility model relates to the field of cigarette equipment technology, and in particular to a fault detection device for a chain drive mechanism and a slicing machine. Background Technology

[0002] In the cigarette production process, cigarette packs need to be cut. Current technology typically uses a slicing machine to cut the cigarette packs. The cutting machine includes blades and a chain drive mechanism. The chain drive mechanism includes a frame, sprockets, and a chain. The sprockets are rotatably connected to the frame, and the chain meshes between two sprockets. The chain is composed of multiple links connected sequentially, with adjacent links connected by pins. The blades are connected to the chain; the rotation of the sprockets drives the chain to rotate, thereby moving the blades to cut the cigarette pack.

[0003] Long-term chain operation can cause the pins to shift, reducing the connection strength of the chain links. Simultaneously, the chain is prone to slackness and breakage, especially when cutting thin tobacco packs. The uneven surface, high internal density, and high resistance of the tobacco packs cause uneven stress on the chain on both sides of the blade, increasing the slicing machine's failure rate. If malfunctions are not detected promptly, continued operation of the slicing machine will lead to shutdown and material shortage, and may even damage the blades, reducing cutting efficiency, increasing maintenance costs, and compromising the slicing machine's safety. Utility Model Content

[0004] The purpose of this invention is to provide a chain drive mechanism fault detection device and a slicer. The chain drive mechanism fault detection device can detect faults such as pin displacement, chain slack and breakage, so as to detect the faults of the slicer in a timely manner.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] On one hand, a chain drive mechanism fault detection device is provided for detecting chain drive mechanisms. The chain drive mechanism includes a frame, sprockets, and a chain. The sprockets are rotatably connected to the frame, and the chain meshes between two sprockets. The chain is composed of multiple links connected sequentially, with adjacent links connected by a pin extending along a first direction. The fault detection device is characterized by comprising:

[0007] A first detection assembly includes a detection element and a first detection component. The detection element is disposed on one side of the chain along the first direction and is rotatable relative to the frame. The first detection component is disposed on the side of the detection element facing away from the chain. The detection element has a normal state and a fault state. When the detection element rotates to the normal state, it blocks the first detection component. When the detection element rotates to the fault state, it does not block the first detection component.

[0008] The second detection assembly includes a slide bar and a second detection element. The slide bar is slidable along a second direction. One end of the slide bar facing the chain abuts against the side of the chain opposite to the sprocket. The second detection element is disposed on the side of the slide bar along the first direction. The slide bar has a normal state and a fault state. When the slide bar moves to the normal state, the slide bar blocks the second detection element. When the slide bar moves to the fault state, the slide bar does not block the second detection element.

[0009] Optionally, two detection elements are provided, spaced apart along the first direction and located on opposite sides of the chain. The two detection elements can rotate synchronously, and the first detection element is located on the side of one of the detection elements facing away from the chain.

[0010] Optionally, the second detection component further includes a base connected to the frame, the base having a mounting hole extending along the second direction, and the slide rod slidably connected to the mounting hole.

[0011] Optionally, the second detection component further includes an elastic element that extends along the second direction, with one end of the elastic element abutting against the side of the base facing the chain and the other end abutting against the slide bar.

[0012] Optionally, the second detection component further includes a limiting member connected to one end of the slide bar facing away from the chain, and the limiting member is capable of abutting against the side of the base facing away from the chain.

[0013] Optionally, the second detection component further includes a roller, which is rotatably connected to one end of the slide bar facing the chain, and the slide bar abuts against the chain through the roller.

[0014] Optionally, the second detection component further includes a fixing member and a connecting rod. The fixing member is fixedly connected to one end of the slide bar facing the chain. The fixing member is provided with a through hole extending along the first direction. The connecting rod passes through the through hole, and the roller is rotatably connected to the connecting rod.

[0015] Optionally, the connecting rod is rotatably connected to the fixing member, and the detection member is fixedly connected to the connecting rod.

[0016] Optionally, the fixing member includes a crossbar and two support rods spaced apart along the first direction. The first ends of the two support rods are connected to the crossbar. The fixing member is U-shaped. The crossbar is connected to the slide rod. The second ends of the two support rods are provided with through holes. The connecting rod passes through the two through holes in sequence.

[0017] On the other hand, a slicer is provided, including a blade, the chain drive mechanism, and the aforementioned chain drive mechanism fault detection device. Two chain drive mechanisms are spaced apart. The blade is disposed between the two chain drive mechanisms and connected to the two chains. The detection element is rotatably connected to the frame, and the slide bar is slidably connected to the frame along the second direction.

[0018] The beneficial effects of this utility model are:

[0019] This utility model provides a chain drive mechanism fault detection device and a slicer. The chain drive mechanism fault detection device is used to detect chain drive mechanisms, which include a frame, sprockets, and a chain. The sprockets are rotatably connected to the frame, and the chain meshes between two sprockets. The chain is composed of multiple links connected sequentially, with adjacent links connected by a pin extending in a first direction. The chain drive mechanism fault detection device includes a first detection component and a second detection component. The first detection component includes a detection element and a first detection element. The detection element has a normal state and a fault state. When the detection element rotates to the normal state, it blocks the first detection element. When the detection element rotates to the fault state, it does not block the first detection element. When the chain is running normally, the detection element is in the normal state, and the pin moves with the chain. When the pin shifts, it abuts against the detection element. The movement of the pin causes the detection element to rotate to the fault state, i.e., the detection element releases its blockage of the first detection element. When the first detection element cannot detect the detection element, it sends a signal.

[0020] The second detection component includes a slide bar and a second detection element. The slide bar has a normal state and a fault state. When the slide bar moves to the normal state, it blocks the second detection element; when the slide bar moves to the fault state, it does not block the second detection element. During normal chain operation, the slide bar is in the normal state. When the chain becomes slack or breaks, because the slide bar is pressed against the chain, it moves along a second direction towards the side closer to the chain to the fault state, i.e., the slide bar releases its blockage of the second detection element. When the second detection element cannot detect the slide bar, it sends a signal. The signal from either the first or second detection element allows the operator to be aware of a fault in the chain drive mechanism, enabling timely repairs and preventing the slicer from stopping and cutting material, avoiding damage to the blades, improving cutting efficiency, reducing maintenance costs, and enhancing the safety of the slicer. Furthermore, this chain drive mechanism fault detection device has a simple structure. Attached Figure Description

[0028] 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 present 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, not the entire structure.

[0029] In the description of this utility model, 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 utility model based on the specific circumstances.

[0030] 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.

[0031] 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 this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0032] like Figure 1 and Figure 2 As shown, this embodiment provides a chain drive mechanism fault detection device for detecting chain drive mechanism 100. The chain drive mechanism 100 includes a frame 101, sprockets 102 and chain 103. The sprockets 102 are rotatably connected to the frame 101. The chain 103 is engaged between two sprockets 102. The chain 103 is composed of multiple chain links connected in sequence. Adjacent chain links are connected by a pin 104. The pin 104 extends along a first direction. The chain drive mechanism fault detection device includes a first detection component 1 and a second detection component 2.

[0033] The first detection assembly 1 includes a detection element 11 and a first detection element 12. The detection element 11 is disposed on one side of the chain 103 along a first direction and is rotatable relative to the frame 101. The first detection element 12 is disposed on the side of the detection element 11 facing away from the chain 103. The detection element 11 has a normal state and a fault state. When the detection element 11 rotates to the normal state, it blocks the first detection element 12. When the detection element 11 rotates to the fault state, it does not block the first detection element 12. When the chain 103 is running normally, the detection element 11 is in the normal state, and the pin 104 moves with the chain 103. When the pin 104 is displaced, it abuts against the detection element 11. The movement of the pin 104 causes the detection element 11 to rotate to the fault state, that is, the detection element 11 releases its blockage of the first detection element 12. When the first detection element 12 cannot detect the detection element 11, it will issue a signal.

[0034] The second detection component 2 includes a slide bar 21 and a second detection element 22. The slide bar 21 can slide along a second direction. One end of the slide bar 21 facing the chain 103 abuts against the side of the chain 103 facing away from the sprocket 102. The second detection element 22 is disposed on one side of the slide bar 21. The slide bar 21 has a normal state and a fault state. When the slide bar 21 moves to the normal state, the slide bar 21 blocks the second detection element 22. When the slide bar 21 moves to the fault state, the slide bar 21 does not block the second detection element 22. When the chain 103 is running normally, the slide bar 21 is in the normal state. When the chain 103 is slack or broken, because the slide bar 21 is pressed against the chain 103, the slide bar 21 will move along the second direction towards the side closer to the chain 103 to the fault state, that is, the slide bar 21 releases its blockage of the second detection element 22. When the second detection element 22 cannot detect the slide bar 21, it will issue a signal.

[0035] The first detection element 12 or the second detection element 22 sends a signal so that the staff can be notified of a malfunction in the chain drive mechanism 100 in a timely manner, and then repair the chain drive mechanism 100 in a timely manner to avoid the slicing machine stopping and material interruption, avoid damage to the blade 200, improve cutting efficiency, reduce maintenance costs, improve the safety of the slicing machine, and the chain drive mechanism fault detection device has a simple structure.

[0036] Specifically, the first direction is the X-direction, which is the width direction of the chain 103. The second direction is the Y-direction, which is a direction perpendicular to the first direction in the horizontal plane. The detection element 11 is a long strip-shaped baffle extending along the second direction. The material of the detection element 11 is stainless steel. The center of the detection element 11 is rotatably connected to the frame 101. One end of the detection element 11 is located on one side of the chain 103 along the first direction and close to the chain 103, so that when the pin 104 moves, it can abut against the detection element 11, thereby driving the detection element 11 to rotate to the fault state. The first detection assembly 1 also includes a first bracket 13, which is long strip-shaped, with one end connected to the frame 101 by screws and the other end connected to the first detection element 12. The first detection element 12 corresponds to the end of the detection element 11 away from the chain 103.

[0037] Specifically, the second detection assembly 2 also includes a second bracket 29, which is elongated and connected at one end to the frame 101 by screws, and at the other end to a second detection element 22. The second detection element 22 is located at the end of the slide bar 21 away from the chain 103, so that when the slide bar 21 moves closer to the chain 103, the obstruction of the second detection element 22 is released, allowing the slide bar 21 to move to the fault state. Both the first detection element 12 and the second detection element 22 are proximity switches. The first detection element 12 and the second detection element 22 are communicatively connected to external equipment. When the chain drive mechanism 100 malfunctions, the signal emitted by the first detection element 12 or the second detection element 22 is transmitted to the external equipment, which can control the slicer to stop running. At the same time, the first detection element 12 or the second detection element 22 will sound an alarm or indicator light, making it easier for staff to detect the fault in time and avoid damage to the slicer.

[0038] Optionally, two detection elements 11 are provided, spaced apart along a first direction and located on both sides of the chain 103. The two detection elements 11 can rotate synchronously, and a first detection element 12 is provided on the side of one of the detection elements 11 facing away from the chain 103. The pin 104 is moved to either end of the chain 103 along the first direction, and the pin 104 can abut against the detection element 11, thereby causing both detection elements 11 to rotate to the fault state simultaneously.

[0039] Optionally, the second detection component 2 also includes a base 23, which is connected to the frame 101. The base 23 is provided with a mounting hole extending in the second direction, and the slide rod 21 is slidably connected to the mounting hole so that the slide rod 21 can move relative to the frame 101.

[0040] Specifically, the base 23 is connected to the frame 101 by screws. The mounting hole has a square cross-section along its radial direction, and the slide rod 21 also has a square cross-section along its radial direction. This prevents the slide rod 21 from rotating relative to the mounting hole, thereby preventing the second detection element 22 from sending incorrect detection signals. Furthermore, the side wall of the slide rod 21 fits snugly against the side wall of the mounting hole, improving the stability of the connection between the slide rod 21 and the mounting hole.

[0041] Optionally, the second detection component 2 further includes an elastic element 24, which extends along the second direction. One end of the elastic element 24 abuts against the side of the base 23 facing the chain 103, and the other end abuts against the slide bar 21. The elastic element 24 enables the slide bar 21 to always press against the chain 103.

[0042] Specifically, the elastic element 24 is a spring, and the elastic element 24 is sleeved on the slide rod 21. In other embodiments, the elastic element 24 may also be a cylindrical structure made of elastic material.

[0043] Optionally, the second detection component 2 further includes a roller 26, which is rotatably connected to the end of the slide bar 21 facing the chain 103. The slide bar 21 abuts against the chain 103 via the roller 26. The roller 26 can rotate relative to the chain 103, making the friction between it and the chain 103 rolling friction, reducing the frictional force between the slide bar 21 and the chain 103, and improving the service life of the chain 103 and the slide bar 21. Specifically, the roller 26 is made of nylon material, giving it strong wear resistance.

[0044] Furthermore, the second detection assembly 2 also includes a fixing member 27 and a connecting rod 28. The fixing member 27 is fixedly connected to the end of the slide bar 21 facing the chain 103. The fixing member 27 is provided with a through hole extending in the first direction. The connecting rod 28 passes through the through hole, and the roller 26 is rotatably connected to the connecting rod 28. By providing the fixing member 27 and the connecting rod 28, the installation of the roller 26 is facilitated. Specifically, the roller 26 is rotatably connected to the connecting rod 28 through a bearing.

[0045] Furthermore, the fixing member 27 includes a crossbar and two support rods spaced apart along the first direction. The first ends of the two support rods are connected to the crossbar. The fixing member 27 is U-shaped. The crossbar is connected to the slide rod 21. The second ends of the two support rods are provided with through holes. The connecting rod 28 passes through the two through holes in sequence, which can improve the stability of the connection between the connecting rod 28 and the fixing member 27.

[0046] Specifically, the end of the slide bar 21 facing the chain 103 is fixedly connected to the center of the crossbar. The slide bar 21 and the crossbar can be connected by means of adhesive or snap-fit, etc., which is not limited in this embodiment. The end of the elastic member 24 away from the base 23 abuts against the side of the crossbar facing the base 23. The roller 26 is disposed between the two support rods.

[0047] Optionally, the connecting rod 28 is rotatably connected to the fixing member 27, and the detection member 11 is fixedly connected to the connecting rod 28, which enables the detection member 11 to be rotatably connected to the frame 101, and makes the chain drive mechanism fault detection device more integrated and saves installation space.

[0048] Specifically, the connecting rod 28 is clearance-fitted with the through hole, allowing the connecting rod 28 to rotate relative to the through hole. Two detection elements 11 are respectively positioned on opposite sides of the two support rods to prevent interference between the detection elements 11 and the roller 26. A positioning hole is formed at the center of the detection element 11, which is interference-fitted onto the connecting rod 28, allowing the detection element 11 to rotate synchronously with the connecting rod 28, thereby enabling the detection element 11 to rotate relative to the frame 101. In this embodiment, the connecting rod 28 is square, and the positioning hole is also square, improving the stability of the connection between the connecting rod 28 and the positioning hole and preventing the detection element 11 from rotating relative to the connecting rod 28.

[0049] Optionally, the second detection component 2 also includes a limiting member 25, which is connected to the end of the slide bar 21 facing away from the chain 103. The limiting member 25 can abut against the side of the base 23 facing away from the chain 103, thereby limiting the movement distance of the slide bar 21 and preventing the slide bar 21 from dislodging from the mounting hole due to excessive displacement when the chain 103 breaks.

[0050] Specifically, the limiting member 25 is a long strip-shaped structure. The limiting member 25 is fixedly connected to the end of the slide bar 21 facing away from the chain 103 by screws. The length of the limiting member 25 is greater than the width of the slide bar 21. Both ends of the limiting member 25 extend to the outside of the end face of the slide bar 21, so that it can abut against the side of the base 23 facing away from the chain 103.

[0051] This embodiment also provides a slicer, including a blade 200, a chain drive mechanism 100, and a chain drive mechanism fault detection device as described above. Two chain drive mechanisms 100 are spaced apart. The blade 200 is positioned between the two chain drive mechanisms 100 and connected to two chains 103. A detection element 11 is rotatably connected to a frame 101, and a slide rod 21 is slidably connected to the frame 101 along a second direction. This slicer can detect faults such as pin 104 displacement and chain 103 slack or breakage, enabling workers to promptly identify these faults.

[0052] Specifically, the chain drive mechanism 100 also includes a drive shaft, which extends along a first direction and is rotatably connected to the frame 101. Two sprockets 102 are respectively fixedly connected to both ends of the drive shaft. The rotation of the drive shaft drives the two sprockets 102 to rotate synchronously, thereby driving the two chains 103 to move synchronously. The slicer also includes a blade holder 300, with blades 200 fixedly connected to the blade holder 300. Both ends of the blade holder 300 along the first direction are respectively fixedly connected to corresponding chains 103. The synchronous movement of the two chains 103 drives the blade holder 300 to move smoothly, thereby driving the blades 200 to move, in order to cut the tobacco pack.

[0053] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. 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 this utility model should be included within the protection scope of the claims of this utility model.
