Description

Technical Field

[0001] This utility model relates to the field of packaging and transportation equipment technology, and in particular to a cardboard stack conveying device. Background Technology

[0002] On the production and transportation lines of materials such as cardboard stacks, it is often necessary to transport and transfer the cardboard stacks. This is achieved by placing cardboard stacks on conveyor belts or modular conveyors.

[0003] To facilitate subsequent processes on the cardboard stack, its position needs to be adjusted to the center of the conveyor belt or module conveyor. Current technology typically uses a separate cardboard stack offset device to adjust the offset stacks on the conveyor line back to the center position to accommodate subsequent processes. However, this offset device is relatively complex. For lighter cardboard stacks, using this device can easily cause wrinkles and edge damage, leading to increased costs and a high defect rate. Utility Model Content

[0004] Therefore, in order to overcome at least some of the defects and deficiencies of the prior art, this utility model provides a cardboard stack conveying device.

[0005] On one hand, an embodiment of this utility model provides a cardboard stack conveying device, comprising: a conveying mechanism; an offset mechanism disposed on one side of the conveying mechanism; a guiding mechanism slidably connected to the offset mechanism and disposed along the width direction of the conveying mechanism; and a driving mechanism drivingly connected to the guiding mechanism and driving the offset mechanism through the guiding mechanism. The offset mechanism includes a push rod portion, a buffer portion, and a support portion. One end of the push rod portion is disposed adjacent to the conveying mechanism, and the other end of the push rod portion is connected to the support portion. The buffer portion is disposed on the side of the push rod portion away from the conveying mechanism. The end of the support portion away from the push rod portion is disposed on the guiding mechanism and slidably connected to the guiding mechanism. The driving mechanism drives the guiding mechanism to move, thereby causing the support portion to reciprocate along the width direction of the conveying mechanism, thereby causing the push rod portion to push the cardboard stack on the conveying mechanism to the center position of the conveying mechanism.

[0006] In one embodiment of the present invention, the buffer part includes a buffer, the push rod part includes a push plate and a push rod, the push plate is disposed on one side of the conveying mechanism, the push plate is hinged to the push rod, the end of the push rod away from the push plate is fixedly connected to the support part, and the buffer is disposed between the push plate and the push rod.

[0007] In one embodiment of this utility model, the pushing direction of the pusher plate is perpendicular to the conveying direction of the conveying mechanism.

[0008] In one embodiment of this utility model, the buffer is a spring buffer or a hydraulic buffer.

[0009] In one embodiment of the present invention, the support portion includes a support plate and a connecting block. One end of the support plate is connected to the push rod, and the connecting block is disposed at the end of the support plate away from the push rod and is slidably connected to the guide mechanism.

[0010] In one embodiment of the present invention, the driving mechanism includes a driving part and a chain tensioning part, the driving part being tractively connected to the chain tensioning part, and the guiding mechanism being provided on the chain tensioning part; the driving part is located on the other side of the conveying mechanism away from the offset mechanism, and the chain tensioning part is located on the bottom end of the conveying mechanism and is arranged along the width direction of the conveying mechanism.

[0011] In one embodiment of the present invention, the driving part includes a driving motor and a driving shaft, the driving motor is fixedly connected to the driving shaft, the chain tensioning part includes a chain, a sprocket and a tensioning member, the end of the driving shaft away from the driving motor is connected to the sprocket, the chain is wound around the sprocket and both ends of the chain are fixedly connected to the connecting block, and the tensioning member is disposed on the end of the chain away from the driving motor.

[0012] In one embodiment of the present invention, the tensioning member includes a tensioning wheel and an adjusting screw. The tensioning wheel is engaged with the chain, and the adjusting screw is used to push the tensioning wheel to move along the tangential direction of the chain.

[0013] In one embodiment of the present invention, the guiding mechanism includes linear guide rails, and at least two linear guide rails are provided, and the two linear guide rails are symmetrically distributed on both sides of the width direction of the conveying mechanism.

[0014] In one embodiment of this utility model, the surface of the pusher plate facing the conveying mechanism is covered with a flexible rubber layer.

[0015] As can be seen from the above, this utility model has the following beneficial effects: This application utilizes an offset mechanism comprising a push rod, a buffer, and a support. The support enables the offset mechanism to slide on the guide mechanism, the push rod offsets the cardboard stack on the conveying mechanism to the center position of the conveying mechanism, and the buffer cushions the push rod.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-4As shown, this utility model embodiment provides a cardboard stack conveying device 1. The cardboard stack conveying device 1 includes, for example, a conveying mechanism 10, an offset mechanism 20, a guiding mechanism 30, and a driving mechanism 40.

[0026] The offset mechanism 20 is disposed on one side of the conveying mechanism 10, for example, on the side of the conveying mechanism not in the conveying direction, to prevent interference with material conveying. The guide mechanism 30 is slidably connected to the offset mechanism 20 and is positioned along the width direction of the conveying mechanism 10 (e.g., along the width direction of the conveying mechanism 10). Figure 1 (As shown in the X direction). The drive mechanism 40 is connected to the guide mechanism 30 and drives the offset mechanism 20 through the guide mechanism 30. The offset mechanism 20 includes a push rod 21, a buffer 22, and a support 23. One end of the push rod 21 is located adjacent to the conveying mechanism 10, and the other end of the push rod 21 is connected to the support 23. The buffer 22 is located on the side of the push rod 21 away from the conveying mechanism 10. The end of the support 23 away from the push rod 21 is located on the guide mechanism 30 and is slidably connected to the guide mechanism 30. The drive mechanism 40 drives the guide mechanism 30 to move, thereby causing the support 23 to reciprocate along the width direction of the conveying mechanism 10, thereby causing the push rod 21 to push the stack of cardboard on the conveying mechanism 10 to the center position of the conveying mechanism 10.

[0027] Specifically, the conveying mechanism 10 can be used to convey and transfer materials, such as stacks of cardboard, and the conveying mechanism 10 can be, for example, a conveyor belt or a conveyor vehicle. The offsetting mechanism 20 is used to push the material and offset it toward the center position of the conveying mechanism 10. The guiding mechanism 30 is used to stabilize and ensure that the offsetting mechanism 20 moves in the X direction. The drive mechanism 40 can be, for example, a combination of a chain and a drive motor. In other embodiments, the conveying mechanism 10 is also provided with a photoelectric sensor, which may include a transmitter and a receiver. The photoelectric sensor is placed near the input end of the conveying mechanism 10 to determine whether the paper stack has completely entered and been placed on the conveying mechanism. The specific principle is that the transmitter emits reflective light, such as infrared or ultraviolet light. When the paper stack has not entered the conveying mechanism 10, the receiver will not receive the light signal. When the paper stack begins to enter the conveying mechanism 10, the receiver receives the reflected light signal. At this time, the paper stack conveying device 1 can know that the paper stack is entering the conveying mechanism 10. When the receiver goes from being able to receive the light signal to not being able to receive the light signal, the paper stack conveying device 1 can determine that the paper stack has been completely transferred and placed on the conveying mechanism 10.

[0028] The working principle of the cardboard stack conveyor 1 is as follows: When the cardboard stack enters the conveying mechanism 10, the drive mechanism 40 drives the guide mechanism 30, which in turn moves the support part 23 of the offset mechanism 20 along the X direction. This causes the push rod part 21 to push the cardboard stack conveyed at the edge toward the center of the conveying mechanism 10. To prevent the push rod part 21 from causing excessive wrinkles and edge damage when pushing cardboard stacks with low basis weights, such as those less than 10 grams, a buffer part 22 ensures that the force is evenly distributed between the push rod part 21 and the cardboard stack when they come into contact, protecting the cardboard from damage. The buffer part 22 provides a certain degree of cushioning for the push rod part 21. Then, the cardboard stack is pushed to the center of the conveying mechanism 10, thus achieving the cardboard stack offset function.

[0029] This embodiment includes a push rod 21, a buffer 22, and a support 23 in the offset mechanism 20. The support 23 enables the offset mechanism 20 to slide on the guide mechanism 30. The push rod 21 offsets the cardboard stack on the conveying mechanism 10 to the center position of the conveying mechanism 10. The buffer 22 buffers the push rod 21. Thus, when the push rod 21 contacts the cardboard with a lower grammage for offset pushing, the cardboard is prevented from wrinkling and the edges are damaged, thereby improving the yield of the cardboard, reducing costs, and centering the cardboard.

[0030] Furthermore, such as Figures 2-3 As shown, the buffer section 22 includes a buffer 221, and the push rod section 21 includes a push plate 211 and a push rod 212. The push plate 211 is disposed on one side of the conveying mechanism 10, and the push plate 211 is hinged to the push rod 212. The end of the push rod 212 away from the push plate 211 is fixedly connected to the support section 23. The buffer 221 is disposed between the push plate 211 and the push rod 212. By setting the buffer 221 between the push plate 211 and the push rod 212, low-grammage cardboard can be protected, solving the problem of easily damaged paper in traditional cardboard stacking devices.

[0031] Furthermore, the pushing direction of the pusher plate 211 (e.g.) Figure 1 The X direction shown) and the conveying direction of the conveying mechanism 10 (e.g., the conveying direction of the conveying mechanism 10) Figure 1 The Y-direction shown is perpendicular to each other, which can prevent the pushing direction of the push plate 211 from affecting the material conveying of the conveying mechanism 10.

[0032] Furthermore, the buffer 221 is a spring buffer or a hydraulic buffer. The buffer can absorb the contact impact force between the pusher plate and the cardboard stack, avoid wrinkles and damage to low-grammage cardboard, and reduce the defect rate.

[0033] Furthermore, such as Figure 2 , Figure 3 and Figure 6As shown, the support portion 23 includes a support plate 231 and a connecting block 232. One end of the support plate 231 is connected to the push rod 212, and the connecting block 232 is disposed at the end of the support plate 231 away from the push rod 212 and is slidably connected to the guide mechanism 30. The connecting block 232 ensures the operation of the offset mechanism 20 on the guide mechanism 30. In this embodiment, the support plate 231 may include two plates, which may be respectively disposed at both ends of the push rod 212.

[0034] Furthermore, such as Figures 2-5 As shown, the drive mechanism 40 includes a drive unit 41 and a chain tensioning unit 42. The drive unit 41 is drively connected to the chain tensioning unit 42, and the guide mechanism 30 is provided on the chain tensioning unit 42. The drive unit 41 is located on the side of the conveying mechanism 10 away from the offset mechanism 20, and the chain tensioning unit 42 is located on the bottom end of the conveying mechanism 10 and is arranged along the width direction of the conveying mechanism 10. The cooperation between the drive unit 41 and the chain tensioning unit 42 simplifies the overall mechanism and reduces the cost of the device.

[0035] Furthermore, the drive unit 41 includes a drive motor 411 and a drive shaft 412, with the drive motor 411 fixedly connected to the drive shaft 412. The chain tensioning unit 42 includes a chain 421, a sprocket 422, and a tensioning member 423. The end of the drive shaft 412 away from the drive motor 411 is connected to the sprocket 422. The chain 421 is wound around the sprocket 422, and both ends of the chain 421 are fixedly connected to the connecting block 232. The tensioning member 423 is disposed on the end of the chain 421 away from the drive motor 411. The two chain links at both ends of the chain 421 are connected to the connecting block 232 fixed on the support plate 231, thereby pulling the support plate 231 to reciprocate on the guide mechanism 30. Replacing the complex cylinder / linkage mechanism with a chain drive can further reduce costs and space requirements.

[0036] Furthermore, such as Figure 5 As shown, the tensioning element 423 includes a tensioning wheel 4231 and an adjusting screw 4232. The tensioning wheel 4231 is engaged with the chain 421, and the adjusting screw 4232 is used to push the tensioning wheel to move along the tangential direction of the chain 421. This allows for real-time adjustment of the chain tension, extending the service life of the chain 421, reducing the frequency of maintenance due to chain loosening, and lowering maintenance costs.

[0037] Furthermore, the guiding mechanism 30 includes linear guide rails 31, of which at least two linear guide rails 31 are symmetrically distributed on both sides of the conveying mechanism 10 in the width direction. The linear guide rails 31 may, for example, be arranged along the X direction. In this embodiment, the number of support plates 231 may also be two, with each support plate 231 respectively disposed on one of the two linear guide rails 31. The symmetrically arranged linear guide rails 31 can evenly support the support plates, preventing the support plates 231 from tilting when sliding along the guide rails, and ensuring smooth movement of the push rod 211.

[0038] Furthermore, such as Figure 1 As shown, the surface of the pusher plate 211 facing the conveying mechanism 10 is covered with a flexible rubber layer 24. The flexible rubber layer further increases the cushioning effect, avoids direct rigid contact between the pusher plate 211 and the cardboard stack, and increases the friction to prevent the pusher plate 211 from sliding relative to the cardboard stack when pushing.

[0039] Furthermore, it is understood that the foregoing embodiments are merely illustrative examples of this utility model. Provided that the technical features do not conflict, the structure is not contradictory, and the utility model's objective is not violated, the technical solutions of the various embodiments can be arbitrarily combined and used.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
