Description

Technical Field

[0001] The utility model relates to the technical field of carton machines, and more particularly to a grooving device and a carton processing device having the same. Background Art

[0002] At present, cartons are usually folded from corrugated cardboard. In order to facilitate users to manually fold the corrugated cardboard, a carton machine is required to perform operations such as indentation, cutting, and grooving on the corrugated cardboard. Among them, the grooving step mainly relies on the horizontal and vertical grooving modules on the carton machine. Some horizontal grooving modules use two relatively arranged grooving knives, and a certain distance is set between the two grooving knives. After the horizontal grooving module cuts a certain distance along the transverse direction of the corrugated cardboard, a slot with a width equal to the distance between the two grooving knives can be formed.

[0003] In the prior art, in order to ensure the cutting smoothness and cutting efficiency of the horizontal grooving module, the grooving knife is usually designed as a rotatable circular blade, and a driving device and a transmission component are added to realize the self-rotation movement of the grooving knife.

[0004] However, due to the influence of the driving device and the transmission component, the distance between the two grooving knives cannot be adjusted, which results in that the horizontal grooving module can only open slots with a fixed width, seriously affecting the processing versatility of the carton machine.

[0024] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The present utility model will be described in detail below with reference to the drawings and in combination with the embodiments.

[0025] It should be pointed out that unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs.

[0026] In the present utility model, unless otherwise stated, the orientation terms such as "upper, lower" are usually in the direction shown in the drawings, or in the vertical, perpendicular or gravitational direction; similarly, for the convenience of understanding and description, "left, right" are usually in the left and right shown in the drawings; "inside, outside" refer to the inside and outside relative to the contour of each component itself, but the above orientation terms do not limit the present utility model.

[0027] To solve the problem that the slotting size of the slotting module of the existing carton machine cannot be adjusted, the present application provides a slotting device and a carton processing device having the same.

[0028] As Figure 1 and Figure 2 shown, the slotting device includes a mounting structure 10, at least two oppositely arranged cutters 20, a driving structure 30 and a driving device 40. The mounting structure 10 includes a movably arranged mounting portion 11. Each cutter 20 is rotatably arranged on the mounting structure 10, and the minimum distance H between the cutting edges of the two oppositely arranged cutters 20 is the width of the slot opening. The driving structure 30 is drivingly connected to the cutter 20 to drive the cutter 20 to rotate. The driving device 40 is drivingly connected to the mounting portion 11 to drive the mounting portion 11 to move. Among them, the mounting portion 11 is correspondingly arranged with at least one cutter 20, so that when the driving device 40 drives the mounting portion 11 to drive the cutter 20 corresponding thereto to move toward or away from another cutter 20, the width of the slot opening can be adjusted.

[0029] Applying the technical solution of this embodiment, the slotting device is used to open a slot opening on a workpiece to be processed. The slotting device includes a mounting structure 10, at least two oppositely arranged cutters 20, a driving structure 30 and a driving device 40. The mounting structure 10 includes a movably arranged mounting portion 11. Each cutter 20 is rotatably arranged on the mounting structure 10. The minimum distance H between the cutting edges of the two oppositely arranged cutters 20 is the width of the slot opening. The driving structure 30 is drivingly connected to the cutter 20 to drive the cutter 20 to rotate, and the driving structure 30 is drivingly connected to the mounting portion 11 to drive the mounting portion 11 to move. Among them, the mounting portion 11 is correspondingly arranged with at least one cutter 20, so that when the driving device 40 drives the mounting portion 11 to drive the cutter 20 corresponding thereto to move toward or away from another cutter 20, the width of the slot opening can be adjusted. In this way, while the driving structure 30 drives the cutter 20 to rotate to enable the slotting device to have a high slotting efficiency, the driving device 40 can also drive the mounting portion 11 to drive the cutter 20 to move, so as to adjust the width of the slot opening opened by the slotting device by adjusting the minimum distance H between the cutting edges of the two cutters 20, thereby solving the problem that the slotting size of the slotting module of the existing carton machine cannot be adjusted and improving the versatility of the slotting device.

[0030] Specifically, the cutter 20 is a circular blade, and the two circular blades are oppositely arranged and parallel to each other, that is, the distance between the two circular blades is the minimum distance H.

[0031] In this embodiment, the workpiece to be processed is a corrugated cardboard. Specifically, after the two oppositely arranged circular blades perform cutting, the corrugated cardboard of the cut portion is removed to form a slot opening.

[0032] It should be noted that the number of the cutting tools 20 is not limited to this, and can be adjusted according to the working conditions and usage requirements. Optionally, the number of the cutting tools 20 is three, or four, or five, or six, or seven, or more.

[0033] As Figure 1 and Figure 2 shown, the mounting structure 10 further includes a main body portion 12. The mounting portion 11 is slidably disposed on the main body portion 12. The driving device 40 is disposed on the main body portion 12 and is drivingly connected to the mounting portion 11. In this way, while the main body portion 12 provides installation support for the driving device 40, the movement of the mounting portion 11 can be realized through the sliding connection between the mounting portion 11 and the main body portion 12, thereby improving the movement stability of the mounting portion 11.

[0034] As Figure 1 and Figure 2 shown, the driving device 40 is a motor. The grooving device further includes a first transmission assembly 50. The driving device 40 is drivingly connected to the mounting portion 11 through the first transmission assembly 50. The first transmission assembly 50 includes a lead screw mechanism 51 and a nut mechanism. The driving device 40 is drivingly connected to the lead screw mechanism 51 to drive the lead screw mechanism 51 to rotate. The nut mechanism is disposed on the mounting portion 11. Among them, the lead screw mechanism 51 has a first threaded section, and the nut mechanism of the mounting portion 11 is sleeved on the first threaded section. In this way, when the driving device 40 drives the lead screw mechanism 51 to rotate, the movement of the mounting portion 11 can be realized through the threaded cooperation between the nut mechanism of the mounting portion 11 and the lead screw mechanism 51.

[0035] Optionally, the lead screw mechanism 51 is a unidirectional lead screw.

[0036] In other embodiments not shown in the drawings, the driving device is a driving cylinder. One of the cylinder body and the piston rod of the driving cylinder is disposed on the main body portion, and the other of the cylinder body and the piston rod is disposed on the mounting portion. Among them, there are at least two driving cylinders, and at least two driving cylinders are disposed in one-to-one correspondence with at least two mounting portions. In this way, the opposite or reverse movement of the mounting portion can also be realized by providing two driving cylinders, thereby making the structure of the driving device more flexible and diverse to adapt to different working conditions and usage requirements, and also improving the processing flexibility of the staff.

[0037] In this embodiment, there are at least two mounting parts 11. The at least two mounting parts 11 are arranged in one-to-one correspondence with at least two cutters 20. The driving device 40 is drivingly connected to all the at least two mounting parts 11 to adjust the width of the notch by driving the at least two mounting parts 11 to move towards or away from each other. In this way, since the driving device 40 is drivingly connected to all the at least two mounting parts 11, the driving device 40 can drive all the at least two mounting parts 11 to drive the cutters to move simultaneously, which not only expands the adjustment range of the notch width, but also further improves the versatility of the grooving device for any notch.

[0038] In this embodiment, there are two mounting parts 11 and two cutters 20. The two cutters 20 and the two mounting parts 11 are arranged in one-to-one correspondence.

[0039] It should be noted that the number of the mounting parts 11 is not limited to this, and can be adjusted according to the working conditions and usage requirements. Optionally, the mounting parts 11 are three, or four, or five, or six, or seven, or more.

[0040] In this embodiment, the lead screw mechanism 51 further has a second thread section. The thread directions of the first thread section and the second thread section are opposite. The nut mechanisms of at least one mounting part 11 are sleeved on the first thread section, and the nut mechanisms of at least another mounting part 11 are sleeved on the second thread section. In this way, since the nut mechanisms (mounting parts 11) are sleeved on both the first thread section and the second thread section with opposite thread directions, the corresponding mounting parts 11 can move towards or away from each other, which not only further expands the adjustment range of the notch width, but also makes the structure for realizing the movement of the mounting parts 11 towards or away from each other simpler. At the same time, the above arrangement also makes the structure of the driving device 40 simpler, reducing the processing difficulty and production cost of the driving device 40.

[0041] In this embodiment, the lead screw mechanism 51 is a bidirectional lead screw, and only one driving device 40 needs to be provided to drive the bidirectional lead screw to rotate.

[0042] Such as Figure 1 and Figure 2As shown, the main body portion 12 is plate-shaped and includes a first plate body 121, a second plate body 122, and a third plate body 123 that are connected to each other. The first plate body 121 and the third plate body 123 are oppositely arranged, and an installation space is formed by surrounding among the first plate body 121, the second plate body 122, and the third plate body 123. At least part of the installation portion 11 is located in the installation space. Among them, at least part of the lead screw mechanism 51 is disposed through the first plate body 121 and the third plate body 123, and the driving device 40 is disposed on the second plate body 122 and located outside the installation space. In this way, while restricting the movement range of the installation portion 11, the installation space formed by surrounding of multiple plate bodies realizes the isolation of the installation portion 11 to avoid movement interference between the installation portion 11 and other devices of the carton processing equipment, which not only improves the running stability of the grooving device, but also improves the running stability of the carton processing equipment. At the same time, since the driving device 40 is located outside the installation space, the size design of the installation space does not need to consider the specifications and dimensions of the driving device 40, thereby reducing the size of the installation space and making the structure of the main body portion 12 more compact and the volume smaller.

[0043] In this embodiment, the first plate body 121 and the third plate body 123 can support the lead screw mechanism 51.

[0044] In this embodiment, the first plate body 121 and the second plate body 122 are arranged at 90°, and the second plate body 122 and the third plate body 123 are arranged at 90°.

[0045] It should be noted that the included angles between the first plate body 121 and the second plate body 122 and between the second plate body 122 and the third plate body 123 are not limited to this, and can be adjusted according to the working conditions and usage requirements.

[0046] Optionally, the included angle between the first plate body 121 and the second plate body 122 is 30°, or 45°, or 60°, or 120° or 135°.

[0047] Optionally, the included angle between the second plate body 122 and the third plate body 123 is 30°, or 45°, or 60°, or 120° or 135°.

[0048] Such as Figure 1 and Figure 2As shown, the driving device 40 is arranged on the second plate body 122. The first transmission assembly 50 further includes a first driving wheel 52, a first driven wheel 53, and a first transmission belt 54. The first driving wheel 52 is sleeved on the output shaft of the driving device 40. The first driven wheel 53 is sleeved on one end of the lead screw mechanism 51 to drive the lead screw mechanism 51 to rotate. The first transmission belt 54 is sleeved on the first driving wheel 52 and the first driven wheel 53, and the first transmission belt 54 rotates synchronously with the first driving wheel 52. Among them, the first driven wheel 53 is located outside the installation space. In this way, the above arrangement of the first transmission assembly 50 can realize the driving connection between the driving device 40 and the lead screw mechanism 51, and at the same time make the installation position of the driving device 40 more appropriate (to avoid interference with the specific structure of the carton processing equipment), thereby making the structure of the slotting device more compact and reasonable. At the same time, the first driven wheel 53 located outside the installation space cannot interfere with the installation part 11 located inside the installation space, which not only improves the transmission stability of the first transmission assembly 50, but also improves the movement stability of the installation part 11.

[0049] In this embodiment, a pressing wheel 70 is arranged on the first plate body 121. The pressing wheel 70 can press the first transmission belt 54 to prevent the first transmission belt 54 from slipping off, further improving the transmission stability of the first transmission assembly 50.

[0050] As Figure 1 and Figure 2 shown, the installation part 11 is plate-shaped and includes a first installation plate body 111 and a second installation plate body 112 connected to each other. The first installation plate body 111 is slidably connected to the main body part 12 through a guide rail slider assembly 60. The cutter 20 is rotatably arranged on the second installation plate body 112. Among them, the nut mechanism is arranged on the second installation plate body 112 of each installation part 11. In this way, on the one hand, the guide rail slider assembly 60 realizes the sliding connection between the installation part 11 and the main body part 12; on the other hand, it can prevent the installation part 11 and the nut mechanism arranged on the installation part 11 from rotating following the lead screw mechanism 51 to ensure the normal realization of the overall transmission function of the lead screw nut mechanism.

[0051] In this embodiment, the guide rail slider assembly 60 includes a guide rail and a slider. The guide rail is arranged on the second plate body 122 and located inside the installation space, and the slider is arranged on the first installation plate body 111.

[0052] In this embodiment, the first installation plate body 111 and the second installation plate body 112 are arranged at 90°.

[0053] It should be noted that the included angle between the first mounting plate body 111 and the second mounting plate body 112 is not limited to this value and can be adjusted according to the working conditions and usage requirements. Optionally, the included angle between the first mounting plate body 111 and the second mounting plate body 112 is 30°, or 45°, or 60°, or 120° or 135°.

[0054] In this embodiment, the nut mechanism is arranged in the mounting hole of the second mounting plate body 112.

[0055] In this embodiment, the lead screw mechanism 51 is actually passed through the first plate body 121, the third plate body 123 and the second mounting plate body 112 of the two mounting parts 11 at the same time.

[0056] As Figure 1 and Figure 2 shown, the driving structure 30 is a driving member 31. The driving member 31 is arranged on the mounting part 11 and moves synchronously with the mounting part 11. There are at least two driving members 31, and the at least two driving members 31 are arranged in one-to-one correspondence with at least two cutting tools 20. Alternatively, the driving structure 30 includes a driving member 31 arranged on the mounting part 11 and a second transmission component 32. The driving member 31 moves synchronously with the mounting part 11 and is drivingly connected to at least two cutting tools 20 through the second transmission component 32. Alternatively, the driving structure 30 includes a driving member 31 arranged on the main body part 12 and a second transmission component 32. The driving member 31 is drivingly connected to at least two cutting tools 20 through the second transmission component 32. In this way, while realizing the driving connection between the driving structure 30 and the cutting tool 20, the structure of the driving structure 30 and the setting position of the driving member 31 are made more flexible and diverse to adapt to different working conditions and usage requirements, and also improve the processing flexibility of the staff.

[0057] In this embodiment, the driving structure 30 includes a driving member 31 arranged on the main body part 12 and a second transmission component 32. The driving member 31 is drivingly connected to at least two cutting tools 20 through the second transmission component 32. In this way, on the one hand, the driving connection between the driving member 31 and at least two cutting tools 20 is realized through the second transmission component 32; on the other hand, since the driving member 31 is arranged on the main body part 12, the driving device 40 does not need to drive the mounting part 11 and the driving member 31 to move at the same time, thereby reducing the driving difficulty of the driving device 40 and increasing the selection range of the driving device 40.

[0058] In this embodiment, the driving member 31 is a motor.

[0059] In other embodiments not shown in the drawings, the driving member is arranged on the mounting part and moves synchronously with the mounting part. There are two driving members, and the two driving members are arranged in one-to-one correspondence with two cutting tools.

[0060] In other embodiments not shown in the drawings, the driving structure includes a driving member disposed on the mounting portion and a second transmission assembly. The driving member moves synchronously with the mounting portion and is drivingly connected to at least two cutting tools through the second transmission assembly.

[0061] As Figure 1 and Figure 2 shown, the driving member 31 is disposed on the main body portion 12. The second transmission assembly 32 includes a rotating shaft 321, a transmission rod 322, a first belt pulley structure 323, and a second belt pulley structure 324. The rotating shaft 321 is rotatably disposed on the second mounting plate body 112. The cutting tool 20 is disposed on the rotating shaft 321 and rotates synchronously with the rotating shaft 321. At least a part of the transmission rod 322 passes through the second mounting plate bodies 112 of the respective mounting portions 11. The second mounting plate bodies 112 are slidably disposed along the extending direction of the transmission rod 322. The first belt pulley structure 323 is disposed between the output shaft of the driving member 31 and the transmission rod 322. The driving member 31 drives the transmission rod 322 to rotate through the first belt pulley structure 323. The second belt pulley structure 324 is disposed between the transmission rod 322 and the rotating shaft 321. The transmission rod 322 drives the rotating shaft 321 to rotate through the second belt pulley structure 324. Among them, the third driving pulley 3241 of the second belt pulley structure 324 is sleeved on the transmission rod 322 and is rotatably connected to the second mounting plate body 112. The third driving pulley 3241 is in anti-rotation cooperation with the transmission rod 322 and is slidably disposed along the extending direction of the transmission rod 322. During the process of the transmission rod 322 driving the third driving pulley 3241 to rotate, the third driving pulley 3241 moves synchronously with the mounting portion 11. In this way, the above arrangement realizes the driving connection between the driving member 31 and the cutting tool 20 through the rotating shaft 321, the transmission rod 322, the first belt pulley structure 323, and the second belt pulley structure 324 on the one hand; on the other hand, since the third driving pulley 3241 is in anti-rotation cooperation with the transmission rod 322 and is slidably disposed along the extending direction of the transmission rod 322, when the transmission rod 322 drives the third driving pulley 3241 to rotate through anti-rotation cooperation, the third driving pulley 3241 can slide along the transmission rod 322, thereby ensuring that the third driving pulley 3241 can move synchronously with the mounting portion 11.

[0062] Specifically, since the third driving pulley 3241 is rotatably connected to the second mounting plate body 112, the third driving pulley 3241 can rotate itself and move synchronously with the mounting portion 11. That is, when the two mounting portions 11 move closer to each other, the mounting portion 11 can push the third driving pulley 3241 to move, and when the two mounting portions 11 move away from each other, the mounting portion 11 can also drive the third driving pulley 3241 to reset.

[0063] In this embodiment, both ends of the transmission rod 322 are cylindrical segments, and between the two cylindrical segments is a polygonal column segment. The two cylindrical segments are respectively rotatably inserted through the first plate body 121 and the third plate body 123. The inner hole shape of the third driving wheel 3241 matches the shape of the polygonal column segment to achieve anti-rotation fit between the two.

[0064] In this embodiment, the polygonal column segment is a hexagonal prism segment.

[0065] In this embodiment, the transmission rod 322 is inserted through the first plate body 121, the third plate body 123, and the second mounting plate body 112 of the two mounting portions 11 to be supported by each structure.

[0066] In this embodiment, the first belt pulley structure 323 is located outside the installation space. The first belt pulley structure 323 includes a second driving wheel 3231, a second driven wheel 3232, and a second transmission belt 3233. The second driving wheel 3231 is sleeved on the output shaft of the driving member 31, the second driven wheel 3232 is sleeved on the cylindrical segment of the transmission rod 322 to drive the transmission rod 322 to rotate, the second transmission belt 3233 is sleeved on the second driving wheel 3231 and the second driven wheel 3232, and the second transmission belt 3233 rotates synchronously with the second driving wheel 3231. A pressing wheel 70 is further provided on the third plate body 123, and the pressing wheel 70 presses the second transmission belt 3233 to improve the transmission stability of the first belt pulley structure 323.

[0067] In this embodiment, the second belt pulley structure 324 includes a third driving wheel 3241, a third driven wheel 3242, and a third transmission belt 3243. The third driving wheel 3241 is sleeved on the polygonal column segment of the transmission rod 322, the third driven wheel 3242 is sleeved on the rotating shaft 321 to drive the rotating shaft 321 to rotate, the third transmission belt 3243 is sleeved on the third driving wheel 3241 and the third driven wheel 3242, and the third transmission belt 3243 rotates synchronously with the third driving wheel 3241. A pressing wheel 70 is further provided on the second mounting plate body 112, and the pressing wheel 70 presses the third transmission belt 3243 to improve the transmission stability of the second belt pulley structure 324.

[0068] In other embodiments not shown in the drawings, only the driving device 40 may be provided (without providing the driving structure 30). At this time, a set of belt pulley assemblies are respectively provided between the driving end of the driving device 40 and the lead screw mechanism 51 and the transmission rod 322, that is, the driving device 40 will drive the lead screw mechanism 51 and the transmission rod 322 to rotate simultaneously, and a one-way bearing is sleeved on the lead screw mechanism 51.

[0069] Specifically, when the driving end of the driving device 40 drives the lead screw mechanism 51 and the transmission rod 322 to rotate clockwise, the lead screw mechanism 51 stops rotating under the action of the one-way bearing (i.e., the outer ring of the bearing rotates relative to the inner ring), and the transmission rod 322 rotates and drives the cutter 20 to rotate to achieve the grooving action. When the driving end of the horizontal grooving driving structure drives the lead screw mechanism 51 and the transmission rod 322 to rotate counterclockwise, the lead screw mechanism 51 starts to rotate under the action of the one-way bearing (i.e., the outer ring of the bearing is stationary relative to the inner ring) to adjust the width of the notch.

[0070] The present application also provides a carton processing device (not shown), which includes a device main body and a grooving device arranged on the device main body. Among them, the grooving device is the above-mentioned grooving device.

[0071] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0072] The grooving device is used to open a notch on a workpiece to be processed. The grooving device includes a mounting structure, at least two oppositely arranged cutters, a driving structure, and a driving device. The mounting structure includes a movably arranged mounting part, and each cutter is rotatably arranged on the mounting part. The minimum distance H between two oppositely arranged cutters is the width of the notch. The driving structure is drivingly connected to the cutter to drive the cutter to rotate, and the driving device is drivingly connected to the mounting part to drive the mounting part to move. Among them, there are at least two mounting parts, and at least two mounting parts and at least two cutters are arranged in one-to-one correspondence. The driving device is drivingly connected to at least one mounting part to adjust the width of the notch when driving the mounting part to drive the corresponding cutter to move towards or away from another cutter. In this way, while the driving structure drives the cutter to rotate to make the grooving device have a high grooving efficiency, the driving device can also drive the mounting part to drive the cutter to move to adjust the width of the notch opened by the grooving device by adjusting the minimum distance H between the two cutters, thereby solving the problem that the grooving size of the grooving module of the existing carton machine cannot be adjusted and improving the versatility of the grooving device.
