Description

Technical Field

[0001] This invention relates to the field of tobacco box conveying technology, and in particular to a tobacco box turning conveying device. Background Technology

[0002] In the processing and handling of tobacco products such as cigarettes, shredded tobacco, tobacco stems, expanded tobacco, and cigarette packs, tobacco boxes are often used to store the materials. Therefore, the transfer of tobacco boxes is an important process.

[0003] However, the sizes of the cigarette boxes are not the same, and the cigarette boxes inevitably have to turn during the conveying process. At present, most of the cigarette box turning is driven by a frustum-shaped roller. Small cigarette boxes can turn smoothly, but large cigarette boxes sometimes get stuck when turning, requiring manual pushing of the cigarette box forward. This not only wastes manpower, but if it is not discovered in time, it will cause the entire cigarette box conveying process to stop, affecting the efficiency of cigarette box conveying. Summary of the Invention

[0004] The purpose of this invention is to provide a solution to the problem mentioned in the background art: during the cigarette box conveying process, turning is inevitable. Currently, most cigarette box turning is driven by frustum-shaped rollers. Small cigarette boxes can turn smoothly, but large cigarette boxes sometimes get stuck when turning, requiring manual pushing of the cigarette box forward. This not only wastes manpower, but also, if not detected in time, will cause the entire cigarette box conveying process to stop, affecting the efficiency of cigarette box conveying.

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

[0006] A cigarette box turning conveyor includes:

[0007] A frame, on which a first support beam and a second support beam are disposed opposite to each other;

[0008] A conveying mechanism includes a rotating shaft, a tapered assembly, a drive assembly, and a sensor. The rotating shaft is rotatably connected to a first support beam. The tapered assembly is sleeved on the end of the rotating shaft opposite to the first support beam. The end of the tapered assembly near the first support beam is rotatably connected to the side wall of the rotating shaft. The drive assembly is mounted on a second support beam and configured to drive the tapered assembly to open or retract. The tapered assembly is rotatable relative to the drive assembly. The sensor is mounted on the second support beam and is aligned with the drive assembly. A motor on the frame drives the rotating shaft to rotate via a belt.

[0009] Optionally, the tapered assembly includes:

[0010] A plurality of arc-shaped support plates are distributed circumferentially along the rotating shaft. One end of each arc-shaped support plate is rotatably connected to the side wall of the rotating shaft. A slide bar is provided on the inner side of each arc-shaped support plate along its extending direction.

[0011] The constraint wheel has a diameter larger than that of the rotating shaft. The constraint wheel has a sliding hole along its circumference that aligns with the slide bar. The slide bar slides through the sliding hole. A rolling bearing is embedded in the constraint wheel. The outer ring of the rolling bearing is fixedly connected to the constraint wheel, and the inner ring of the rolling bearing is fixedly connected to the output end of the drive assembly.

[0012] Optionally, the arc-shaped support plate is provided with a rotating part at one end near the rotating shaft, and a rotating seat is fixedly provided on the side wall of the rotating shaft, which is aligned with the rotating part, and the rotating part is rotatably connected to the rotating seat.

[0013] Optionally, the driving component includes:

[0014] A cylinder is mounted on the second support beam, and the output end of the cylinder passes through the inner ring of the rolling bearing, and the output end of the cylinder is fixedly connected to the inner ring of the rolling bearing.

[0015] A solenoid valve is disposed on one side of the cylinder and is connected to the air passage of the cylinder.

[0016] A controller is disposed on one side of the cylinder and is electrically connected to the solenoid valve. The sensor is electrically connected to the controller.

[0017] Optionally, an anti-slip layer is provided on the outer side of the arc-shaped support plate.

[0018] Optionally, the rotating shaft has a limiting groove along its circumference, and the belt is embedded in the limiting groove.

[0019] Optionally, the rotating shaft has a first toothed groove along its circumference, the inner side of the belt has teeth that mate with the first toothed groove, the output end of the motor is provided with a drive pulley, and the drive pulley has a second toothed groove along its circumference that mates with the teeth.

[0020] Optionally, the first support beam and the second support beam are arranged in parallel.

[0021] Optionally, a cylindrical roller is rotatably mounted on the frame, and the cylindrical roller is driven by the motor via the belt.

[0022] The beneficial effects of this invention are:

[0023] The cigarette box turning conveyor device provided by this invention, by setting up a drive component and a conical component, can increase the speed difference between the inner and outer sides of the cigarette box, preventing the large cigarette box from getting stuck. When the large cigarette box turns, the sensor can detect it in time and quickly transmit the signal to the drive component. The drive component drives the conical component to open. Since the rotating shaft is driven by a motor on the frame via a belt, the rotation of the rotating shaft causes the conical component to rotate relative to the drive component. The angular velocity of the end of the conical component near the rotating shaft is the same as that of the end of the conical component near the drive component. After opening, the diameter of the conical component near the drive component increases, which increases the linear velocity of the conical component near the drive component, thereby increasing the speed difference between the inner and outer sides of the large cigarette box. Moreover, the height of the conical component near the drive component increases after opening, reducing the centrifugal force when the large cigarette box passes by, thus ensuring that the large cigarette box turns smoothly. By using this cigarette box turning conveyor device, it is possible to avoid the large cigarette box sometimes getting stuck when turning, eliminating the need for manual pushing of the cigarette box, saving manpower, reducing the stagnation of the entire cigarette box conveying process, and ensuring the efficiency of cigarette box conveying.

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.

[0037] Embodiments of the present invention are described in detail below. Examples of these embodiments are illustrated 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 intended to explain the present invention, and should not be construed as limiting the present invention.

[0038] like Figures 1 to 5 As shown, the present invention provides a cigarette box turning conveyor device, including a frame 100 and a conveying mechanism 200.

[0039] The frame 100 has a first support beam 110 and a second support beam 120 arranged opposite to each other. The conveying mechanism 200 includes a rotating shaft 210, a conical component 220, a drive component 230, and a sensor 240. The rotating shaft 210 is rotatably connected to the first support beam 110. The conical component 220 is sleeved on the end of the rotating shaft 210 away from the first support beam 110. The end of the conical component 220 near the first support beam 110 is rotatably connected to the side wall of the rotating shaft 210. The drive component 230 is arranged on the second support beam 120 and is configured to drive the conical component 220 to open or close. The conical component 220 can rotate relative to the drive component 230. The sensor 240 is arranged on the second support beam 120 and is aligned with the drive component 230. The motor on the frame 100 drives the rotating shaft 210 to rotate via a belt 130. For example, the motor drives the belt 130 to rotate, and the rotation of the belt 130 drives the shaft 210 to rotate, thereby realizing that the motor drives the shaft 210 to rotate through the belt 130.

[0040] The cigarette box turning conveyor device provided by this invention, by setting up a drive assembly 230 and a conical assembly 220, can increase the speed difference between the inner and outer sides of the cigarette box, preventing the large cigarette box 10 from getting stuck. When the large cigarette box 10 turns, the sensor 240 can detect the large cigarette box 10 in time and quickly transmit the signal to the drive assembly 230. The drive assembly 230 drives the conical assembly 220 to open. Since the rotating shaft 210 is driven by the motor on the frame 100 through the belt 130, the rotation of the rotating shaft 210 causes the conical assembly 220 to rotate relative to the drive assembly 230. The angular velocities of the end of the conical component 220 near the drive component 230 are the same at the end of the rotating shaft 210 and the end of the conical component 220 near the drive component 230. The opening of the conical component 220 increases the diameter of the end near the drive component 230, thus increasing its linear velocity and increasing the velocity difference between the inner and outer sides of the large tobacco box 10. Furthermore, the opening of the conical component 220 increases its height of the end near the drive component 230, reducing the centrifugal force when the large tobacco box 10 passes through, thereby ensuring smooth turning of the large tobacco box 10. By using this tobacco box turning conveyor, the large tobacco box 10 can be prevented from sometimes getting stuck during turns, eliminating the need for manual pushing of the tobacco box, saving manpower, reducing stagnation in the entire tobacco box conveying process, and ensuring the efficiency of tobacco box conveying.

[0041] In some embodiments, the first support beam 110 and the second support beam 120 are arranged parallel to each other to ensure the stability of the support for the conveying mechanism 200. A limiting groove is formed on the rotating shaft 210 along its circumference, and the belt 130 is embedded in the limiting groove. By providing the limiting groove, the belt 130 can be prevented from disengaging during the rotation of the rotating shaft 210, ensuring the reliability of the belt 130's drive on the rotating shaft 210. A cylindrical roller 140 is rotatably mounted on the frame 100, and the cylindrical roller 140 is driven by a motor via the belt 130. The cylindrical roller 140 conveys the cigarette box to the conveying mechanism 200.

[0042] Optionally, the rotating shaft 210 has a first toothed groove along its circumference, and the inner side of the belt 130 has teeth that mate with the first toothed groove. The output end of the motor is provided with a drive pulley, and the drive pulley has a second toothed groove along its circumference that mates with the teeth. This structure prevents slippage between the belt 130 and the rotating shaft 210, ensuring the stability of the belt 130 drive. Preferably, the cylindrical roller 140 has a third toothed groove along its circumference that mates with the teeth.

[0043] In some embodiments, the tapered assembly 220 includes a plurality of arc-shaped support plates 221 and a constraint wheel 223. The plurality of arc-shaped support plates 221 are distributed circumferentially along the rotating shaft 210. One end of the arc-shaped support plate 221 is rotatably connected to the side wall of the rotating shaft 210. A slide bar 222 is provided on the inner side of the arc-shaped support plate 221 along the extending direction of the arc-shaped support plate 221. The diameter of the constraint wheel 223 is larger than the diameter of the rotating shaft 210. The constraint wheel 223 has a sliding hole 224 aligning with the slide bar 222 along its circumference. The slide bar 222 slides through the sliding hole 224. A rolling bearing 225 is embedded in the constraint wheel 223. The outer ring of the moving bearing 225 is fixedly connected to the constraint wheel 223, and the inner ring of the rolling bearing 225 is fixedly connected to the output end of the drive assembly 230. With this structure, when the rotating shaft 210 rotates with the arc-shaped support plate 221, the drive assembly 230 can drive the rolling bearing 225 to move the constraint wheel 223. The constraint wheel 223 slides relative to the slide bar 222 through the sliding hole 224, thereby causing one end of the arc-shaped support plate 221 to rotate relative to the side wall of the rotating shaft 210, thus enabling the arc-shaped support plate 221 to open or close. The rolling bearing 225 can reduce the frictional force experienced by the arc-shaped support plate 221 during rotation. For example, the number of arc-shaped support plates 221 can be six.

[0044] Optionally, the arc-shaped support plate 221 has a rotating part 226 near one end of the rotating shaft 210, and a rotating seat 211 corresponding to the rotating part 226 is fixedly provided on the side wall of the rotating shaft 210. The rotating part 226 and the rotating seat 211 are rotatably connected. Specifically, the rotating part 226 has a first circular hole, and the rotating seat 211 has a second circular hole corresponding to the rotating part 226. A cylindrical pin passes through the first circular hole and the second circular hole. Exemplarily, the cylindrical pin can be fixedly connected to the first circular hole and rotatably connected to the second circular hole; or, the cylindrical pin can be fixedly connected to the first circular hole and rotatably connected to the second circular hole; or the cylindrical pin can be rotatably connected to both the first and second circular holes.

[0045] To prevent the smoke box from slipping relative to the arc-shaped support plate 221 during the conveying process, an anti-slip layer is provided on the outer side of the arc-shaped support plate 221, thereby increasing the friction between the smoke box 10 and the arc-shaped support plate 221.

[0046] In some embodiments, the drive assembly 230 includes a cylinder 231, a solenoid valve 232, and a controller 233. The cylinder 231 is mounted on the second support beam 120, and its output end passes through the inner ring of the rolling bearing 225 and is fixedly connected to the inner ring of the rolling bearing 225. The solenoid valve 232 is mounted on one side of the cylinder 231 and is connected to the air passage of the cylinder 231. The controller 233 is mounted on one side of the cylinder 231 and is electrically connected to the solenoid valve 232. The sensor 240 is electrically connected to the controller 233. Through the above structure, the sensor 240 sends a detected smoke box signal to the controller 233. The controller 233 controls the solenoid valve 232 according to the signal. The solenoid valve 232 controls the air passage of the cylinder 231, thereby controlling the extension or retraction of the output end of the cylinder 231.

[0047] Of course, in other embodiments, the drive assembly 230 may include a linear motor and a controller 233. The linear motor is mounted on the second support beam 120, and its output end passes through the inner ring of the rolling bearing 225 and is fixedly connected to the inner ring of the rolling bearing 225. The controller 233 is mounted on one side of the linear motor, and the linear motor is electrically connected to the controller 233. The sensor 240 is electrically connected to the controller 233. With the above structure, for cigarette boxes of different sizes, by controlling the output end of the linear motor to extend to different lengths, the arc-shaped support plate 221 can be driven to open to different degrees, thereby ensuring that cigarette boxes of different sizes can turn smoothly.

[0048] It should be noted that the specific model and specifications of the above-mentioned electrical appliances can be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here. Furthermore, the power supply and principle of the electrical appliances are clear to those skilled in the art, and will not be described in detail here.

[0049] The working principle of the cigarette box turning conveyor provided by this invention is as follows:

[0050] When the tobacco box turns, on the one hand, the speed of the side of the tobacco box near the outer circumference must be greater than the speed near the inner circumference. On the other hand, to counteract centrifugal force, the height of the outer side of the tobacco box must be higher than the height of the inner side. In this invention, the belt 130 drives the rotating shaft 210 to rotate, and the rotating shaft 210 drives the arc-shaped support plate 221 to rotate. At the turning point of the tobacco box, the sensor 240 can detect the size of the tobacco box in time and quickly transmit the signal to the controller 233. The controller 233 controls the extension and retraction of the cylinder 231 through the solenoid valve 232. When the sensor 240 detects the large tobacco box 10, the controller 233 controls the output end of the cylinder 231 to extend through the solenoid valve 232. The output end of the cylinder 231 pushes the rolling bearing 225 to drive the constraint wheel 223 to move towards the rotating shaft 210. The constraint wheel 223 moves through the sliding hole 224. Sliding the slide bar 222 causes one end of the arc-shaped support plate 221 to rotate relative to the side wall of the rotating shaft 210, thereby opening the arc-shaped support plate 221. This increases the speed difference between the inner and outer sides of the large smoke box 10, and increases the height of the outer side of the large smoke box 10, reducing the centrifugal force, thus ensuring that the large smoke box 10 can turn smoothly. When the sensor 240 detects the small smoke box 20, the controller 233 controls the output end of the cylinder 231 to retract through the solenoid valve 232. The output end of the cylinder 231 drags the rolling bearing 225 to move the constraint wheel 223 away from the rotating shaft 210. The constraint wheel 223 slides relative to the slide bar 222 through the sliding hole 224, thereby causing one end of the arc-shaped support plate 221 to rotate relative to the side wall of the rotating shaft 210, thereby retracting the arc-shaped support plate 221, thus ensuring that the small smoke box 20 can turn smoothly.

[0051] 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.
