Description

Technical Field

[0001] This utility model relates to the field of automated production technology, and in particular to a counting mechanism and a conveying device. Background Technology

[0002] Conveying devices for cigarette production refer to mechanical systems used in the cigarette manufacturing process to transport materials from upstream equipment to downstream equipment. Their core function is to ensure stable material transport while meeting the needs of different production stages.

[0003] In cigarette production, the conveyor system uses a pulse counter to record the number of pulses to measure the distance the conveyor belt travels, thereby tracking the material position in real time and calculating the material flow rate. However, in existing technologies, the uncertainty of the conveyor belt's position when it stops can easily cause the pulse counter to miscount, affecting the accuracy of the conveyed material quantity and even leading to material shortages or blockages, thus disrupting normal production. Utility Model Content

[0004] The purpose of this utility model is to provide a counting mechanism and a conveying device to solve the problem in the prior art that the uncertainty of the position when the conveyor belt stops can easily cause the pulse counting device to miscount, thereby affecting the accuracy of the conveyed material quantity, or even causing material shortage or blockage, thus affecting the normal production of products.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] On one hand, this utility model provides a counting mechanism for measuring the moving distance of a conveying device, the conveying device comprising a plurality of conveyor plate chains connected in sequence, and the counting mechanism comprising:

[0007] A sensing component, wherein the sensing component is disposed on the conveying device;

[0008] A triggering component includes a support bracket and a sensing bracket. The support bracket is mounted on the conveying device, and the sensing bracket is rotatably mounted on the support bracket. A sensing head and a contact head are respectively connected to both ends of the sensing bracket. When the contact head contacts the surface of the conveyor chain, the sensing head disengages from the sensing component. When the contact head falls into the gap between two adjacent conveyor chains, the sensing head triggers the sensing component.

[0009] A drive assembly, the two ends of which are respectively connected to the support bracket and the sensing bracket; the drive assembly is used to drive the sensing bracket to rotate so that the contact head always moves toward the side closer to the conveyor chain;

[0010] An anti-reverse component is provided on the support bracket and can abut against the side of the sensing bracket near the contact head; when the driving component drives the sensing bracket to rotate, the anti-reverse component can prevent the sensing head from disengaging from the sensing component.

[0011] As an alternative to the above-mentioned counting mechanism, the driving component includes a first connector, a second connector, and an elastic member. One end of the elastic member is connected to the support bracket through the first connector, and the other end of the elastic member is connected to the sensing bracket through the second connector.

[0012] As an alternative to the above-mentioned counting mechanism, the support bracket has a U-shaped groove, a portion of the elastic element is located in the U-shaped groove, and the first connector can pass through the support bracket and connect to the elastic element in the U-shaped groove.

[0013] As an alternative to the above-mentioned counting mechanism, the triggering component further includes a third connector, with a portion of the sensing bracket located within the U-shaped groove. The third connector can pass through the support bracket and connect to the sensing bracket within the U-shaped groove.

[0014] As an alternative to the above-mentioned counting mechanism, the sensing bracket has a through groove, a portion of the elastic element is located in the through groove, and the second connector can pass through the sensing bracket and connect to the elastic element in the through groove.

[0015] As an alternative to the above-mentioned counting mechanism, the contact head is provided with a threaded rod, the sensing bracket is provided with a threaded hole, and the threaded rod is threadedly connected to the threaded hole.

[0016] As an alternative to the aforementioned counting mechanism, the sensing head has a sheet-like structure.

[0017] As an alternative to the aforementioned counting mechanism, the contact head has an arc-shaped structure on the side near the conveyor chain.

[0018] As an alternative to the aforementioned counting mechanism, the anti-reverse component is detachably connected to the support bracket.

[0019] On the other hand, the present invention provides a conveying device, including the counting mechanism as described above.

[0020] The beneficial effects of this utility model are as follows:

[0021] The counting mechanism includes a sensing component, a triggering component, a driving component, and a stop component. The sensing component is mounted on the conveyor and records the number of pulses to facilitate calculation of the conveyor's travel distance. The triggering component includes a support bracket and a sensing bracket. The support bracket is mounted on the conveyor, and the sensing bracket is rotatably mounted on the support bracket. A sensing head and a contact head are connected to both ends of the sensing bracket, allowing the sensing head and contact head to be adjusted as the sensing bracket rotates on the support bracket. Specifically, when the contact head swings downwards, the sensing head swings upwards, and vice versa. When the contact head contacts the surface of the conveyor chain, the sensing head disengages from the sensing component. When the contact head falls into the gap between two adjacent conveyor chains, the sensing head triggers the sensing component. During the movement of several conveyor chains, the contact head can repeatedly move between contacting the conveyor chain surface and falling into the gap between two adjacent conveyor chains, allowing the sensing head to repeatedly swing to disengage from or enter the triggering component, thus recording the number of pulses. Meanwhile, the drive assembly is connected to a support bracket and a sensing bracket at both ends. The drive assembly drives the sensing bracket to rotate so that the contact head always moves towards the side closest to the conveyor chain, thereby ensuring contact between the contact head and the surface of the conveyor chain and falling into the gap between two adjacent conveyor chains. The anti-reverse component is located on the support bracket and can abut against the side of the sensing bracket near the contact head. When the drive assembly drives the sensing bracket to rotate, the anti-reverse component can prevent the sensing head from disengaging from the sensing assembly. This ensures the stability and accuracy of the counting mechanism in measuring the movement of the conveying device. That is, when several conveyor chains are conveying forward, stopping, and reversing, the anti-reverse component can resist the excessive rotation of the sensing bracket, so that the sensing head can only enter or leave the sensing assembly from one direction, preventing the counting mechanism from miscounting and avoiding affecting the accuracy of the conveyed material quantity. Furthermore, it avoids material shortages or blockages that could affect normal product production. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection of 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.

[0028] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0029] like Figure 1 As shown, this embodiment provides a counting mechanism for measuring the travel distance of a conveying device, which includes a plurality of conveyor plate chains connected in sequence. Optionally, the conveying device is a conveying device for cigarette production.

[0030] The counting mechanism includes a sensing component, a triggering component 1, a driving component 2, and a stop component 3. The sensing component is located on the conveying device and can record the number of pulses to facilitate the calculation of the moving distance of the conveying device. Optionally, the sensing component is a photoelectric sensor switch.

[0031] The triggering component 1 includes a support bracket 11 and a sensing bracket 12. The support bracket 11 is mounted on the conveying device, and the sensing bracket 12 is rotatably mounted on the support bracket 11. The two ends of the sensing bracket 12 are respectively connected to a sensing head 121 and a contact head 122. Thus, when the sensing bracket 12 rotates on the support bracket 11, the positions of the sensing head 121 and the contact head 122 can be adjusted. That is, when the contact head 122 swings downward, the sensing head 121 swings upward, and when the contact head 122 swings upward, the sensing head 121 swings downward.

[0032] When the contact head 122 contacts the surface of the conveyor chain, the sensing head 121 disengages from the sensing component. When the contact head 122 falls into the gap between two adjacent conveyor chains, the sensing head 121 triggers the sensing component. That is, during the movement of several conveyor chains, the contact head 122 can repeatedly move between contacting the surface of the conveyor chain and falling into the gap between two adjacent conveyor chains, allowing the sensing head 121 to repeatedly oscillate to disengage from or enter the triggering sensing component, thereby recording the pulse count. Optionally, the sensing head 121 has a sheet-like structure to facilitate the sensing head 121 in blocking the sensing component, improving the accuracy of pulse count recording. Further optionally, the sensing head 121 and the sensing bracket 12 are integrally formed.

[0033] Meanwhile, the two ends of the drive assembly 2 are respectively connected to the support bracket 11 and the sensing bracket 12. The drive assembly 2 is used to drive the sensing bracket 12 to rotate so that the contact head 122 always moves towards the side closer to the conveyor chain, thereby ensuring that the contact head 122 contacts the surface of the conveyor chain and falls into the gap between two adjacent conveyor chains. The anti-reverse assembly 3 is provided on the support bracket 11 and can abut against the side of the sensing bracket 12 near the contact head 122. When the drive assembly 2 drives the sensing bracket 12 to rotate, the anti-reverse assembly 3 can stop the sensing head 121 from disengaging from the sensing assembly. This can ensure the stability and accuracy of the counting mechanism in measuring the movement of the conveying device. That is, when several conveyor chains are conveying forward, stopping, and reversing, the anti-reverse assembly 3 can resist the transitional rotation of the sensing bracket 12, so that the sensing head 121 can only enter or leave the sensing assembly from one direction, preventing the counting mechanism from miscounting and avoiding affecting the accuracy of the conveyed material quantity. Furthermore, it can prevent material shortages or blockages that would affect normal product production.

[0034] Specifically, the drive assembly 2 includes a first connector 21, a second connector 22, and an elastic element 23. One end of the elastic element 23 is connected to the support bracket 11 via the first connector 21, and the other end of the elastic element 23 is connected to the sensing bracket 12 via the second connector 22. Thus, the elastic element 23 can drive the sensing bracket 12 to rotate relative to the support bracket 11 through its elastic force, causing the contact head 122 to always move towards the side closer to the conveyor chain. This structure is simple and convenient for the production and manufacturing of the counting mechanism. Optionally, both the first connector 21 and the second connector 22 can be connecting pins, and the elastic element 23 can be a return spring.

[0035] Furthermore, the support bracket 11 has a U-shaped groove 111, with a portion of the elastic element 23 located within the U-shaped groove 111. The first connector 21 can pass through the support bracket 11 and connect to the elastic element 23 within the U-shaped groove 111. The U-shaped groove 111 can limit one end of the elastic element 23, preventing it from shifting during extension and retraction and affecting the driving of the sensing bracket 12. Simultaneously, the sensing bracket 12 has a through groove 123, with a portion of the elastic element 23 located within the through groove 123. The second connector 22 can pass through the sensing bracket 12 and connect to the elastic element 23 within the through groove 123. The through groove 123 can limit the other end of the elastic element 23, preventing it from shifting during extension and retraction and affecting the driving of the sensing bracket 12.

[0036] The trigger assembly 1 further includes a third connector 13. A portion of the sensing bracket 12 is located within the U-shaped groove 111. The third connector 13 can pass through the support bracket 11 and connect to the sensing bracket 12 within the U-shaped groove 111. Thus, while the third connector 13 is fixedly connected to the support bracket 11, it can also act as a pivot, allowing the sensing bracket 12 to rotate relative to the support bracket 11. Furthermore, a portion of the elastic element 23 and a portion of the sensing bracket 12 are located within the U-shaped groove 111, facilitating the connection of the other end of the elastic element 23 to the sensing bracket 12. Optionally, the third connector 13 is a connecting screw.

[0037] Furthermore, the contact head 122 is provided with a threaded rod 1221, and the sensing bracket 12 has a threaded hole 124. The threaded rod 1221 is threadedly connected to the threaded hole 124. The threaded connection between the threaded rod 1221 and the threaded hole 124 facilitates the installation of the contact head 122. By adjusting the installation length of the threaded rod 1221 within the threaded hole 124, the position of the contact head 122 relative to the sensing bracket 12 can be adjusted to meet the requirements of actual working conditions. Optionally, the side of the contact head 122 near the conveyor chain has an arc-shaped structure, which can reduce the wear when the contact head 122 contacts the conveyor chain and prevent scratching the conveyor chain.

[0038] Furthermore, the anti-backlash component 3 is detachably connected to the support bracket 11, allowing for the replacement of anti-backlash components 3 of different lengths as needed to meet actual working conditions. That is, when replacing different models of sensing components, replacing the anti-backlash component 3 with the corresponding length can prevent the anti-backlash component 3 from failing and causing the counting mechanism to miscount. Optionally, the anti-backlash component 3 is an anti-backlash rod bolted to the support bracket 11.

[0039] This embodiment also provides a conveying device, including the counting mechanism as described above. By using the counting mechanism as described above, the conveying device can prevent the sensing bracket 12 from rotating during forward conveying, stopping and reversing of several conveyor chains. This is achieved by using the anti-reverse component 3 to press against the sensing bracket 12 for transitional rotation, so that the sensing head 121 can only enter or leave the sensing component from one direction. This prevents the counting mechanism from miscounting, avoids affecting the accuracy of the conveyed material quantity, and further avoids material shortages or blockages that could affect normal product production.

[0040] 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 other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations 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.
