Speed regulating mechanism for transmission shaft of carton mechanical paper collecting unit

Abstract

This utility model discloses a speed adjustment mechanism for the transmission shaft of a cardboard box receiving section, relating to the field of transmission shaft speed adjustment technology. The utility model includes a frame, and further includes a transmission shaft rotatably connected between the rear ends of the frame's two inner sides near the top. By providing a speed adjustment component inside the fixed frame, the active and driven pulleys can be simultaneously adjusted left and right by pushing the connecting vertical plate left and right with an electric push rod during use. This adjusts the width of the V-shaped grooves formed between the active and driven cone discs and between the active and driven cone discs and their inner sides, thereby adjusting the contact radius between the transmission steel belt and the inner sides of the active and driven cone discs. When the contact radius between the transmission steel belt and the inner side of the active cone disc increases, the contact radius with the driven cone disc decreases, resulting in a faster transmission shaft speed; conversely, a smaller contact radius decreases the transmission shaft speed, thus achieving efficient and precise adjustment of the transmission shaft speed.

Description

Technical Field

[0001] This utility model belongs to the field of transmission shaft speed regulation technology, and in particular relates to a speed regulation mechanism for the transmission shaft of the paper receiving section of a carton machine. Background Technology

[0002] The cardboard box receiving section is a component of a cardboard box printing machine. Its main function is to collect and organize the printed cardboard boxes for subsequent processing or packaging. When using the cardboard box receiving section for cardboard box collection, a speed adjustment mechanism is needed to adjust the rotation of the drive shaft to synchronously transmit and collect the cardboard boxes with the cardboard box printing machine.

[0003] The existing speed adjustment mechanism for the drive shaft of the paper receiving section of carton machinery uses gears of different diameters to adjust the speed of the drive shaft during application, thereby ensuring that the speed of the drive shaft is synchronized with the paper receiving operation of the carton printing machine. However, the gear diameter is fixed, and the drive shaft can only be adjusted to a specific speed. This presents a technical problem that the drive shaft speed cannot be adjusted to any speed for paper receiving operations in an efficient, stable and precise manner. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a speed adjustment mechanism for the transmission shaft of the paper receiving part of a carton machine, which can effectively solve the problems of the existing technology.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a speed adjustment mechanism for the transmission shaft of a cardboard box receiving section, comprising a frame and further comprising: a transmission shaft rotatably connected between the rear ends of the two sides of the frame near the top; a fixed frame is provided at the top of one side of the frame; a drive motor is provided at the front end of one side of the fixed frame; an electric push rod is provided at the middle position of one side of the fixed frame; an active cone disc is provided inside the fixed frame at the output end of the drive motor; an active pulley is provided on one side of the active cone disc; a driven cone disc is provided inside the fixed frame on one side of the transmission shaft; a driven pulley is provided on one side of the driven cone disc; a transmission steel belt is provided between the inner sides of the active cone disc and the active pulley and the inner sides of the driven cone disc and the driven pulley; and a transmission limiting component is provided between the front end of the two sides of the frame and one side of the transmission shaft.

[0007] Furthermore, the transmission steel belt has a trapezoidal cross-section, and the side of the transmission steel belt is in contact with the inner sides of the driving cone disc and the driving pulley, as well as the inner sides of the driven cone disc and the driven pulley.

[0008] Furthermore, a connecting vertical plate is rotatably connected at the middle position between the outer side of the active pulley and the outer side of the driven pulley, and a fixed rod is fixedly connected between the connecting vertical plates. One side of the electric push rod is fixedly connected to the outer side of the connecting vertical plate.

[0009] Furthermore, a connecting shaft is provided at the midpoint between the inner sides of the active pulley and the driven pulley, and limiting blocks are provided at both ends of the outer side of the connecting shaft. A shrinkage groove is provided at the midpoint between the inner sides of the active cone and the driven cone.

[0010] Furthermore, the limiting block is symmetrically arranged on the outside of the insertion shaft, and one side of the insertion shaft and the limiting block are inserted into the interior of the shrinkage groove, and the insertion shaft and the limiting block can slide back and forth inside the shrinkage groove.

[0011] Furthermore, the transmission limiting assembly includes a guide roller, which is rotatably connected to the front end near the top between the two sides inside the frame. A pulley is provided on one side of the guide roller and the outside of the transmission shaft, and a transmission belt is provided between the outer sides of the pulley.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model features a speed-regulating component installed on the inner side of the fixed frame. During use, the driving pulley and driven pulley can be simultaneously adjusted left and right by pushing the connecting vertical plate left and right with an electric push rod. This adjusts the width of the V-groove formed between the driving cone and the driving pulley, as well as between the driven cone and the driven pulley. Consequently, the contact radius between the transmission steel belt and the inner sides of the driving and driven cones is adjusted. When the contact radius between the transmission steel belt and the inner side of the driving cone increases, the contact radius with the driven cone decreases, resulting in a faster transmission shaft speed. Conversely, a smaller contact radius slows down the transmission shaft speed, thus achieving efficient and precise adjustment of the transmission shaft speed.

[0014] 2. This utility model has a transmission limiting component between the front end between the two sides inside the frame and one side outside the transmission shaft. When the speed of the transmission shaft is increased or decreased, the guide roller is driven to rotate in the same direction and at the same speed through the pulley and the transmission belt. The guide roller can stably and continuously convey and guide the paper wound by the transmission shaft. It is highly feasible. Attached Figure Description

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please see Figure 1-4 As shown, this utility model is a speed adjustment mechanism for the transmission shaft of the paper receiving section of a carton machine. It includes a frame 1 and a transmission shaft 3 rotatably connected between the rear ends of the two sides of the frame 1 near the top. A fixed frame 4 is provided on the top of one side of the frame 1, and a drive motor 5 is provided at the front end of one side of the fixed frame 4. The drive motor 5 can drive the transmission shaft 3 to rotate for paper receiving operations.

[0024] As a further implementation of this embodiment, such as Figure 1-4As shown, an electric push rod 6 is installed at the middle position on one side of the fixed frame 4. An active cone disc 12 is installed inside the fixed frame 4 at the output end of the drive motor 5. An active pulley 11 is installed on one side of the active cone disc 12. A driven cone disc 8 is installed inside the fixed frame 4 on one side of the transmission shaft 3. A driven pulley 14 is installed on one side of the driven cone disc 8. A connecting vertical plate 13 is rotatably connected at the middle position between the outer side of the active pulley 11 and the outer side of the driven pulley 14. A fixed rod 18 is fixedly connected between the connecting vertical plates 13. One side of the electric push rod 6 is fixedly connected to the outer side of the connecting vertical plate 13. The electric push rod 6 is used to drive the drive shaft 5. Pushing the connecting vertical plate 13 left and right simultaneously adjusts the driving pulley 11 and the driven pulley 14, thereby adjusting the width of the V-groove formed between the driving cone plate 12 and the driving pulley 11, and between the driven cone plate 8 and the driven pulley 14. A transmission steel belt 7 is provided between the inner sides of the driving cone plate 12 and the driving pulley 11 and the inner sides of the driven cone plate 8 and the driven pulley 14. The cross-section of the transmission steel belt 7 is trapezoidal, and the side of the transmission steel belt 7 fits against the inner sides of the driving cone plate 12 and the driving pulley 11, as well as the inner sides of the driven cone plate 8 and the driven pulley 14, thus adjusting the width of the V-groove formed between the driving cone plate 12 and the driving pulley 11, and between the driven cone plate 8 and the driven pulley 14. When the width of the V-groove formed between the driven cone disc 8 and the driven pulley 14 is adjusted, the contact radius between the transmission steel belt 7 and the inner sides of the driving cone disc 12 and the driven cone disc 8 changes accordingly. By increasing the contact radius between the transmission steel belt 7 and the inner side of the driving cone disc 12, the contact radius between the transmission steel belt 7 and the driven cone disc 8 decreases, thus increasing the speed of the transmission shaft 3. Conversely, decreasing the contact radius slows down the speed of the transmission shaft 3. A connecting shaft 15 is provided at the midpoint between the inner sides of the driving pulley 11 and the driven pulley 14. Limiting blocks 16 are provided at both ends of the outer side of the connecting shaft 15, and the limiting blocks 16 are positioned at the connecting... The outer side of the shaft 15 is symmetrically arranged. A contraction groove 17 is provided at the middle position of the inner side of the driving cone disk 12 and the inner side of the driven cone disk 8. One side of the insertion shaft 15 and the limiting block 16 is inserted into the interior of the contraction groove 17, and the insertion shaft 15 and the limiting block 16 can slide back and forth inside the contraction groove 17. When the driving pulley 11 and the driven pulley 14 are adjusted to move horizontally, the insertion shaft 15 and the limiting block 16 move accordingly in the contraction groove 17. The limiting block 16 can ensure that the driving cone disk 12 and the driving pulley 11 and the driven cone disk 8 and the driven pulley 14 rotate synchronously, thus ensuring transmission efficiency.

[0025] When in use, pulling the electric push rod 6 to the left moves the connecting vertical plate 13, which is fixedly connected by the fixing rod 18. This simultaneously adjusts the leftward movement of the driving pulley 11 and the driven pulley 14, narrowing the V-groove between the driving cone disc 12 and the driving pulley 11, increasing the contact radius between the transmission steel belt 7 and the inner sides of the driving cone disc 12 and the driving pulley 11. Correspondingly, this widens the V-groove between the driven cone disc 8 and the driven pulley 14, reducing the contact radius between the transmission steel belt 7 and the inner sides of the driven cone disc 8 and the driven pulley 14. This adjusts and increases the speed of the transmission shaft 3. Conversely, pushing the connecting vertical plate 13 to the right with the electric push rod 6 simultaneously adjusts the leftward movement of the driving pulley 11 and the driven pulley 14. The driven pulley 14 moves to the right, widening the V-groove between the driving cone 12 and the driving pulley 11, reducing the contact radius between the transmission steel belt 7 and the inner sides of the driving cone 12 and the driving pulley 11. Correspondingly, the V-groove between the driven cone 8 and the driven pulley 14 narrows, increasing the contact radius between the transmission steel belt 7 and the inner sides of the driven cone 8 and the driven pulley 14. This adjusts and slows down the speed of the transmission shaft 3. When the driving pulley 11 and the driven pulley 14 move horizontally, the insertion shaft 15 and the limiting block 16 move accordingly within the contraction groove 17 to ensure that the driving cone 12 and the driving pulley 11, as well as the driven cone 8 and the driven pulley 14, rotate in the same direction and at the same speed.

[0026] As a further implementation of this embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, a transmission limiting assembly is provided between the front end of the inner two sides of the frame 1 and one side of the outer side of the transmission shaft 3. The transmission limiting assembly includes a guide roller 2, which is rotatably connected to the front end of the inner two sides of the frame 1 near the top. A pulley 9 is provided between the guide roller 2 and one side of the outer side of the transmission shaft 3. A transmission belt 10 is provided between the outer sides of the pulley 9. When the transmission shaft 3 rotates, the guide roller 2 is driven to rotate simultaneously through the pulley 9 and the transmission belt 10 between them to stably and continuously guide the paper wound by the transmission shaft 3. When the speed of the transmission shaft 3 increases, the guide roller 2 rotates faster. When the speed of the transmission shaft 3 decreases, the speed of the guide roller 2 decreases.

[0027] When the speed of the drive shaft 3 is increased or decreased, the pulley 9 on its outer side and the guide roller 2 on its outer side, and the drive belt 10 between them drive the guide roller 2 at the top front end between the two sides inside the frame 1 to rotate in the same direction and at the same speed, so that the guide roller 2 can stably and continuously convey and guide the paper wound by the drive shaft 3.

[0028] Working Principle: When using the drive shaft speed adjustment mechanism, the drive motor 5 drives the active cone disc 12 and the active pulley 11 to rotate, which in turn drives the driven cone disc 8 and the driven pulley 14 to rotate via the transmission steel belt 7. This, in turn, drives the drive shaft 3 to transmit and collect the cardboard boxes. When the speed of the drive shaft 3 needs to be adjusted, the electric push rod 6 is activated to pull the connecting vertical plate 13 to the left, thus adjusting the movement of the active pulley 11 and the driven pulley 14 to the left. This narrows the V-groove between the active cone disc 12 and the active pulley 11, increasing the contact radius between the transmission steel belt 7 and the inner sides of the active cone disc 12 and the active pulley 11. Correspondingly, this widens the V-groove between the driven cone disc 8 and the driven pulley 14, narrowing the contact radius between the transmission steel belt 7 and the inner sides of the driven cone disc 8 and the driven pulley 14. This adjusts and increases the speed of the drive shaft 3. The electric push rod 6 then pushes the connecting vertical plate 13 to the left. Moving plate 13 to the right simultaneously adjusts the movement of both the driving pulley 11 and the driven pulley 14 to the right, widening the V-groove between the driving cone 12 and the driving pulley 11 and reducing the contact radius between the transmission steel belt 7 and the inner sides of the driving cone 12 and the driving pulley 11. Correspondingly, this narrows the V-groove between the driven cone 8 and the driven pulley 14, increasing the contact radius between the transmission steel belt 7 and the inner sides of the driven cone 8 and the driven pulley 14. This allows the rotational speed of the transmission shaft 3 to be adjusted and slowed down. At the same time, the insertion shaft 15 and the limiting block 16 can move within the shrinkage groove 17 to ensure that the driving cone 12 and the driving pulley 11, as well as the driven cone 8 and the driven pulley 14, rotate in the same direction and at the same speed. When the rotational speed of the transmission shaft 3 is increased or decreased, the guide roller 2 is driven to rotate in the same direction and at the same speed through the pulley 9 and the transmission belt 10 to stably and continuously guide the paper wound by the transmission shaft 3.

[0029] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
