Description

Technical Field

[0001] The present invention relates to the technical field of conveying devices, and more specifically, it relates to a corrugated cardboard conveying device. Background Art

[0002] Corrugated cardboard is a lightweight and high-strength material composed of multiple layers of cardboard bonded together by adhesives. It gets its name from its special wavy sandwich structure. Its core feature is to enhance the compressive and buffering properties through the wavy design of the corrugations. It is widely used in packaging, transportation, warehousing and other fields, and is one of the indispensable environmentally friendly packaging materials in modern industry.

[0003] After corrugated cardboard is produced, it needs to be transported. The existing corrugated cardboard transportation methods mainly include: manual handling equipment, such as handcarts and manual forklifts, but their efficiency is low, they rely on manpower, the handling speed is slow, and it is difficult to meet the large-volume transportation requirements; conveyor belt devices, but the existing conveying devices have a large floor area, fixed length, and need to be fixedly installed, with poor flexibility. At the same time, when corrugated cardboard is transported, problems such as dislocation and offset will occur. Therefore, there is an urgent need to set up a corrugated cardboard conveying device to solve the above problems. Summary of the Invention

[0004] (1) Technical Problems to be Solved

[0005] In view of the problems existing in the prior art, the present invention provides a corrugated cardboard conveying device to solve the technical problems of time-consuming and laborious manual handling and poor flexibility of conveyor belts mentioned in the background art.

[0006] (2) Technical Solutions

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] A corrugated cardboard conveying device includes a first conveying device, a second conveying device and a clamping device. The first conveying device includes a first crawler belt, a first motor, a first frame, first rollers, first rotating shafts and a support mechanism. There are two first rotating shafts, and both are rotatably connected to both sides of the first frame. The first frame is inclined. There are two first rollers, and both are sleeved on the surfaces of the two first rotating shafts. The first crawler belt is sleeved on the surface of the first rollers. The output shaft of the first motor is fixedly connected to the first rotating shaft. The support mechanism is rotatably connected to the first frame. The second conveying device includes an inner bracket, an outer bracket, support legs, rollers, a connection mechanism, a transmission mechanism and a length adjustment mechanism. The inner bracket is slidably connected to the outer bracket through the connection mechanism. Support legs are provided at the bottoms of the inner bracket and the outer bracket. Rollers are provided at the bottoms of the support legs. The transmission mechanism is connected to the inner bracket.

[0009] The present invention is further configured such that the support mechanism includes a first support frame and a fixing rod. A number of limiting holes are provided on the first support frame. The fixing rod passes through the limiting holes and is rotatably connected to the first frame. The first frame can adjust its height through the limiting holes and the fixing rod, and thus can be used for conveying work at different heights, with a wide range of applications.

[0010] The present invention is further configured such that the connecting mechanism includes a first screw rod and a nut. A sliding groove is provided on the outer support. A first screw rod is provided on the inner support. One end of the first screw rod is connected with a nut. The inner support and the outer support are slidably connected by the first screw rod passing through the sliding groove, and thus the length of the second conveying device can be adjusted.

[0011] The present invention is further configured such that the transmission mechanism includes a second track, a baffle, a second motor, a second roller and a second rotating shaft. There are two second rotating shafts, which are symmetrically arranged on both sides of the inner support. The second roller is sleeved on the surface of the second rotating shaft. The second track is sleeved on the surface of the second roller. The output shaft of the second motor is fixedly connected with one end of the second rotating shaft. The other end of the second rotating shaft is connected with the baffle. The second motor drives the second rotating shaft to rotate, the second rotating shaft drives the second roller to rotate, and the second roller drives the second track to rotate, so as to convey the corrugated cardboard conveyed by the first conveying mechanism.

[0012] The present invention is further configured such that the length adjusting mechanism includes a third rotating shaft, a pulley, a second support frame, a first fixing plate and an electric push rod. The first fixing plate is fixedly connected to the lower end surface of the outer support. The electric push rod is arranged on the upper end surface of the first fixing plate. The second support frame is arranged on the upper end surface of the electric push rod. A number of third rotating shafts are provided, which are arranged on the second support frame at equal intervals. Three pulleys are sleeved on each of the third rotating shafts. When the length needs to be adjusted, the second support frame is pushed upward by the electric push rod, so that the height of the pulley and the third rotating shaft is the same as that of the second track.

[0014] The present invention is further configured such that the second conveying devices are arranged symmetrically in the reverse direction, and the two second conveying devices operate in cooperation to realize the conveying of the corrugated cardboard.

[0015] (III) Beneficial effects

[0016] Compared with the prior art, the present invention provides a corrugated cardboard conveying device, which has the following beneficial effects:

[0017] 1. By setting the first conveying device in the present invention, the first rack is installed at an inclined angle. The first motor drives the first rotating shaft to drive the first roller to rotate, so that the first track sleeved on the surface of the roller forms a continuous conveying surface. The corrugated cardboard is automatically conveyed from a low place to a high place by using the inclined angle and the friction force of the track. Through the cooperation of the limiting hole and the fixing rod in the supporting mechanism, the inclined height of the first rack can be adjusted to meet the requirements of different loading heights. This device replaces the traditional manual handling, improves the work efficiency, and the height of the first rack can be adjusted through the limiting hole and the fixing rod, and thus can be used for conveying work at different heights, with a wide range of applications.

[0018] 2. By setting the second conveying device in the present invention, the inner bracket and the outer bracket are connected through the sliding groove and the first screw rod. Turning the nut can push the inner bracket to expand and contract along the sliding groove, changing the overall length of the second conveying device. In the transmission mechanism, the second motor drives the second roller to drive the second track to operate, which is connected with the first conveying device to receive and continue to convey the corrugated cardboard. The length adjusting mechanism controls the lifting of the second support frame through the electric push rod, so that the pulley is flush with the second track, and thus the second conveying device is lengthened. This device can freely adjust the conveying length according to the transportation distance requirements, and the height of the pulley and the second track is synchronously adjusted to avoid the corrugated cardboard getting stuck or offset due to the length change.

[0019] 3. By setting the clamping device in the present invention, turning the turning handle can adjust the width between the clamping plates, and the clamping width can be dynamically adjusted according to the size of the corrugated cardboard, which is compatible with different specifications of corrugated cardboard and reduces the offset and dislocation during transportation.

There are two first rollers 4, and both are sleeved on the surfaces of the two first rotating shafts 5. The first crawler 1 is sleeved on the surface of the first roller 4. The output shaft of the first motor 2 is fixedly connected to the first rotating shaft 5. The supporting mechanism is rotatably connected to the first frame 3. The second conveying device includes an inner support 6, an outer support 7, a support leg 8, a roller 9, a connecting mechanism, a transmission mechanism and a length adjusting mechanism. The inner support 6 and the outer support 7 are slidably connected through the connecting mechanism. Support legs 8 are provided at the bottoms of the inner support 6 and the outer support 7. Rollers 9 are provided at the bottoms of the support legs 8. The transmission mechanism is connected to the inner support 6.

[0030] In a further embodiment, the support mechanism includes a first support frame 10 and a fixing rod 11. A number of limiting holes 12 are formed in the first support frame 10. The fixing rod 11 passes through the limiting holes 12 and is rotatably connected to the first rack 3. The first rack 3 can adjust its height through the limiting holes 12 and the fixing rod 11, so as to be applicable to conveying work at different heights.

[0031] In a further embodiment, the connecting mechanism includes a first screw rod 13 and a nut 14. A sliding groove 15 is formed in the outer support 7. The first screw rod 13 is arranged on the inner support 6. One end of the first screw rod 13 is connected with the nut 14. The inner support 6 and the outer support 7 are slidably connected through the first screw rod 13 passing through the sliding groove 15. The transmission mechanism includes a second track 16, a baffle 17, a second motor 18, a second roller 19 and a second rotating shaft 20. There are two second rotating shafts 20, and they are symmetrically arranged on both sides of the inner support 6. The second roller 19 is sleeved on the surface of the second rotating shaft 20. The second track 16 is sleeved on the surface of the second roller 19. The output shaft of the second motor 18 is fixedly connected with one end of the second rotating shaft 20. The other end of the second rotating shaft 20 is connected with the baffle 17.

[0032] The inner support 6 and the outer support 7 are connected through the sliding groove 15 and the first screw rod 13. By screwing the nut 14, the inner support 6 can be pushed to expand and contract along the sliding groove 15, changing the overall length of the second conveying device. In the transmission mechanism, the second motor 18 drives the second roller 19 to drive the second track 16 to operate, connect with the first conveying device, receive and continue to convey the corrugated board.

[0033] In a further embodiment, the length adjusting mechanism includes a third rotating shaft 21, a pulley 22, a second support frame 23, a first fixing plate 24 and an electric push rod 25.

The second support frame 23 is arranged on the upper end surface of the electric push rod 25. A number of third rotating shafts 21 are arranged, and they are equally spaced on the second support frame 23. Three pulleys 22 are sleeved on each of the third rotating shafts 21.

[0034] The length adjusting mechanism controls the lifting of the second support frame 23 through the electric push rod 25, so that the pulleys 22 are flush with the second track 16, thereby lengthening the second conveying device. This device can freely adjust the conveying length according to the transportation distance requirement. The height of the pulleys 22 is adjusted synchronously with that of the second track 16, avoiding the corrugated board from jamming or shifting due to the length change. When the lengthening is not needed, the electric push rod 25 drives the second support frame 23 to contract, and the nut 14 is screwed to push the inner support 6 back.

[0035] In a further embodiment, the clamping device includes a second fixing plate 26, a rotating handle 27, a second screw 28, and a clamping plate 29.

The rotating handle 27 is fixedly connected to one end of the second screw 28, and the clamping plate 29 is fixedly connected to the other end of the second screw 28. The second screw 28 passes through the threaded hole 30 and is rotatably connected to the second fixing plate 26. Rotating the rotating handle 27 drives the second screw 28 to rotate, and the second screw 28 drives the clamping plate 29 to move, so that the width between the clamping plates 29 can be adjusted. The clamping width can be dynamically adjusted according to the size of the corrugated cardboard, compatible with corrugated cardboard of different specifications, and reducing offset and dislocation during transportation.

[0036] In a further embodiment, the second conveying devices are arranged symmetrically in reverse, and the two second conveying devices operate in cooperation to realize the conveying of the corrugated cardboard.

[0037] In summary, when the overall equipment is in use:

[0038] In the present invention, after the first motor 2 is started, it drives the first rotating shaft 5 fixed to its output shaft to rotate, drives the two first rollers 4 sleeved on the first rotating shaft 5 to rotate synchronously, and the first rollers 4 drive the first track 1 sleeved on its surface to rotate. Since the first frame 3 is inclined, the corrugated cardboard is automatically conveyed from a lower place to the second conveying device under the action of the friction force of the first track 1. By matching the limiting holes 12 on the first support frame 10 with the fixing rod 11, the inclination angle and height of the first frame 3 can be adjusted to meet the requirements of different loading and unloading scenarios.

[0039] The corrugated cardboard is conveyed to the second conveying device. The second motor 18 drives the second rotating shaft 20 to rotate, drives the second roller 19 and the second track 16 to operate. If it is necessary to change the length of the second conveying device, loosen the nut 14, push the inner support 6 along the sliding groove 15 of the outer support 7, adjust the relative position of the inner support 6 and the outer support 7 through the first screw 13 to change the overall length of the second conveying device. Start the electric push rod 25 of the length adjustment mechanism to push the second support frame 23 to rise, so that the pulley 22 on the third rotating shaft 21 is flush with the second track 16 to ensure the continuity of the conveying surface of the extended section. When the extension is not required, the electric push rod 25 drives the second support frame 23 to contract, and turn the nut 14 to push the inner support 6 back.

[0040] Rotate the rotating handle 27 of the clamping device, drive the second screw 28 to rotate in the threaded hole 30, drive the clamping plate 29 to move horizontally along the second fixing plate 26, and adjust the distance between the two clamping plates 29 on both sides. According to the actual width of the corrugated cardboard, adjust the clamping plate 29 to an appropriate distance to form a stable clamping channel. During the conveying process, the clamping plate 29 continuously restricts the lateral movement of the cardboard to prevent offset caused by inertia or vibration.

[0041] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which will not be described one by one here. In the above, all fixed connections are preferably welded.

Since the devices matched with the controller are common devices, their control principles and line connections are all well-known and mature technologies, and their electrical connection relationships and specific circuit structures are not described here.

[0043] In all the solutions mentioned above, the motor involved can be matched with a reducer if actually needed. The connection structure and working principle between the motor and the reducer are existing well-known technologies, and the present invention will not elaborate on them.

[0044] Among all the solutions mentioned above, those involving the connection between solar panels and batteries can be equipped with necessary accessories such as inverters, battery charging controllers, cables, fuses, and brackets.
