Description

Technical Field

[0001] The utility model relates to the field of paperboard production and manufacturing, in particular to a paperboard unloading and transferring device. Background Art

[0002] The raw paper material is cut, pressed, glued, bonded, printed, trimmed and creasing by various devices in the cardboard production line to produce corrugated cardboard. The produced corrugated cardboards are transported one by one by a conveyor belt to the end of the cardboard production line for unloading. There is a unloading device, which is arranged at the end of the cardboard production line, opposite to the front of the conveyor belt. The unloading device includes a receiving plate for receiving the corrugated cardboard, and the plane where the receiving plate is located is lower than the upper surface of the conveyor belt. Vertical side panels extend upward at the left edge, right edge and front edge of the receiving plate, respectively, wherein the left and right side panels limit and guide the cardboard in the left and right directions, and the front side panel blocks the front of the conveyor belt, leaving a certain distance between the conveyor belt and the front side panel, which is equivalent to the dimension of the corrugated cardboard in the front and rear directions. The prepared corrugated cardboard is conveyed forward by the conveyor belt until it passes over the front of the conveyor belt and moves to the top of the receiving plate of the unloading device, and then continues to move forward for a distance under the action of inertia (limited and guided by the left and right side plates in this process) until it hits the front side plate, and then stops moving forward and falls freely to the receiving plate below under the action of its own gravity, and one corrugated cardboard is unloaded; multiple corrugated cardboards are conveyed by the conveyor belt one by one and repeat the above unloading operation, and are stacked one by one on the receiving plate of the unloading device until the upper surface of the top corrugated cardboard stacked on the receiving plate is higher than the upper surface of the conveyor belt. At this time, the unloading device is in a fully loaded state and cannot continue to unload. The production staff needs to use a forklift to fork away the unloading device and the multiple stacked corrugated cardboards on it. Since the height difference between the upper surface of the receiving plate and the upper surface of the conveyor belt determines the unloading capacity of the unloading device, the lower the height of the receiving plate, the greater the unloading capacity. However, if the height difference is too large, there will be the following two defects: first, it will cause the corrugated cardboard to deflect more backwards when it falls freely (it will rebound backwards after hitting the front side plate), causing the stacked corrugated cardboards to tilt backwards more, which is not safe enough; second, it will cause the corrugated cardboard to be damaged when it falls freely onto the receiving plate.

[0003] There is another type of unloading device, in which a vertical telescopic motor is provided at the bottom of the receiving plate. Under the action of the telescopic rod of the telescopic motor, the receiving plate can first rise horizontally until the height difference between the upper surface of the receiving plate and the upper surface of the conveyor belt is within a reasonable range. Then, the receiving plate receives the corrugated cardboard as above, and descends horizontally under the action of the telescopic rod of the telescopic motor, so that the height difference between the upper surface of the top corrugated cardboard stacked on the receiving plate and the upper surface of the conveyor belt is always maintained within a reasonable range. Since the height difference is always maintained within a reasonable range during the unloading process, the above two disadvantages do not exist. This unloading device needs to occupy a certain space below the receiving plate because a vertical telescopic motor needs to be provided at the bottom of the receiving plate. Therefore, when the receiving plate is horizontally descended to the lowest point, the maximum height difference between its upper surface and the upper surface of the conveyor belt is smaller than that of the first type of unloading device, and the unloading capacity is correspondingly smaller. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a cardboard unloading and transferring device, which can maintain the height difference between the upper surface of a receiving plate and the upper surface of a conveyor belt within a reasonable range during the cardboard unloading process, and has a larger unloading capacity.

[0005] To solve the above problems, the utility model provides a cardboard unloading and transferring device, including a receiving plate and a first telescopic motor for driving the receiving plate to rise and fall horizontally, including a front side plate arranged at the front of the receiving plate, and also including limit side plates located at the left and right sides of the receiving plate. The telescopic rod of the first telescopic motor faces downward and is arranged on the front side surface of the upper part of the front side plate. A vertical first guide groove running through the front and back is opened on the front side plate. The front part of the receiving plate is accommodated in the first guide groove, passes through the first guide groove to the front side surface of the front side plate, and is connected to the bottom of the telescopic rod of the first telescopic motor. The receiving plate is driven by the first telescopic motor to rise and fall horizontally relative to the front side plate to receive the material.

[0006] Furthermore: there are two first telescopic motors, one on the left and one on the right, which are arranged on the left and right sides of the front side surface of the front side plate; and there are two first guide grooves accordingly.

[0007] Furthermore, a flip plate and a driving motor for driving the flip plate are provided on the top of the front side plate. When driven by the forward rotation of the driving motor, the flip plate flips forward relative to the front side plate to be flush with the front side plate, serves as an extension of the front side plate, and blocks the advancement of the cardboard together with the front side plate; when driven by the reverse rotation of the driving motor, the flip plate flips backward relative to the front side plate to above the receiving plate, and together with the receiving plate, presses and fixes the cardboard that has been unloaded onto the receiving plate.

[0008] Furthermore, a second vertical guide groove running through the front and back is opened at the top of the front side plate, and the lower part of the flip plate close to the front side plate partially extends toward the second guide groove to form a flip part, which is accommodated in the second guide groove and movably connected to the front side plate.

[0009] Furthermore: a vertical slot is formed on the wall of the second guide groove, and left and right horizontal connecting rods are fixedly installed in the flipping part of the flip plate, and the ends of the connecting rods are inserted into the slots in a movable manner; the driving motor specifically drives the connecting rod to rotate forward or reversely around the horizontal axis relative to the slot, thereby driving the flip plate to realize the forward flipping or backward flipping.

[0010] Furthermore, it comprises a second telescopic motor, whose telescopic rod is connected to the flipping part of the flip plate, and can drive the flipping part of the flip plate to descend along the second guide groove after the flip plate flips backward so that the flip plate is close to the receiving plate.

[0011] Furthermore: the telescopic rod of the second telescopic motor extends upward, and a mounting plate is installed on the top of the telescopic rod. The mounting plate has through holes in the left and right directions. The connecting rod passes through and is accommodated in the through holes and can rotate relative to the mounting plate. The flipping part of the flip plate is installed on the mounting plate through the connecting rod; the extension and retraction of the telescopic rod drives the mounting plate together with the connecting rod and the flip plate installed thereon to rise and fall along the second guide groove.

[0012] Furthermore, a first bevel gear is fixedly installed in the middle of the connecting rod, and the driving motor is specifically installed on the mounting plate. The rotating shaft of the driving motor extends toward the connecting rod, and a second bevel gear is installed at the end. The first bevel gear and the second bevel gear are meshed with each other, and the driving motor drives the connecting rod thereby.

[0013] Furthermore, it comprises a base, the front side plate and the receiving plate are both mounted on the base, and self-locking wheels with locking function are mounted on the four corners of the bottom of the base.

[0014] Beneficial effects: On the one hand, the receiving plate can be raised and lowered horizontally driven by the first telescopic motor, so that during the cardboard unloading process, the height difference between the upper surface of the receiving plate and the upper surface of the conveyor belt can be maintained within a reasonable range, so that the stacked multiple corrugated cardboards tilt backward less, which is safer, and the cardboards are not easily damaged when they fall freely onto the receiving plate; on the other hand, since the first telescopic motor is arranged on the front side surface of the upper part of the front side plate with the telescopic rod facing downward, it does not need to be arranged under the receiving plate, so it does not occupy the space under the receiving plate, so the receiving plate can be lowered lower, the height difference between the upper surface of the receiving plate and the upper surface of the conveyor belt is larger, and the unloading capacity is also larger.

DETAILED DESCRIPTION

[0023] The present invention is further described in detail below in conjunction with specific implementation methods.

[0024] After the corrugated cardboard is made, Figure 1 The paperboard is transported forward by the conveyor belt 1 to the cardboard unloading and transfer device 2 located in front of the conveyor belt 1 for unloading and transfer. Figure 2 , including a base 21, and self-locking wheels 22 with locking function are installed at the four corners of the bottom of the base 21 to facilitate the movement and transportation of the cardboard unloading and transfer device 2. A receiving plate 23 and left and right limiting side plates 24 located on the left and right sides of the receiving plate 23 are provided above the base 21. The upper parts of the left and right limiting side plates 24 are both tilted outward, so that the space between the two limiting side plates 24 is in the shape of a trumpet with a larger upper part and a smaller lower part. In this way, after the corrugated cardboard (not shown in the figure) leaves the conveyor belt 1, it will be limited and guided by the left and right limiting side plates 24 during the process of freely falling to the receiving plate 23. The structure and principle of the left and right limiting side plates 24 are conventional technologies and will not be repeated here.

[0025] A front side plate 25 is provided at the front of the receiving plate 23, and the bottom of the front side plate 25 is welded and installed on the base 21. Figure 2 The two first telescopic motors 31 are installed on the left and right sides of the front side surface of the upper part of the front side plate 25, and both telescopic rods 311 (see Figure 5) downward; the front side plate 25 is provided with two vertical first guide grooves 251 that penetrate from front to back, and the two first guide grooves 251 are also one on the left and one on the right, respectively aligned with the telescopic rods 311 of the two first telescopic motors 31. The parts of the front of the receiving plate 23 that are aligned with the two first guide grooves 251 are partially extended forward, and are respectively accommodated in the two first guide grooves 251, and pass through the two first guide grooves 251 to the front side of the front side plate 25, and are connected to the bottom of the telescopic rods 311 of the two first telescopic motors 31. In this way, the receiving plate 23 is connected to the two first telescopic motors 31 through its front part, and is installed on the front side plate 25 through the two first telescopic motors 31. Driven by the two first telescopic motors 31, the receiving plate 23 can be horizontally lifted relative to the front side plate 25 to receive materials.

[0026] See Figure 4 The top of the front side plate 25 is partially left empty, and two vertical second guide grooves 252 (combined with Figure 3 ), the two second guide grooves 252 are arranged at intervals, one on the left and one on the right. A flip plate 26 is provided at the top of the front side plate 25, and the lower part of the flip plate 26 close to the front side plate 25 partially extends toward the two second guide grooves 252 to form a flip portion 261, and the two flip portions 261 are respectively accommodated in the two second guide grooves 252. A vertical left clamping groove 254 is opened on the left groove wall of the left second guide groove 252, and a vertical right clamping groove 254 is opened on the right groove wall of the right second guide groove 252, and the left and right clamping grooves 254 are respectively connected to the top wall of the front side plate 25. A left and right horizontal connecting rod 27 is provided at the flip portion 261 of the flip plate 26, and the connecting rod 27 horizontally passes through the two flip portions 261 (combined with the flip portion 261 of the flip plate 26) Figure 6 ), so that the two flip parts 261 are fixedly mounted on the connecting rod 27; the left and right ends of the connecting rod 27 are respectively inserted into the left and right slots 254, and can rotate around their own horizontal axis relative to the slots 254 and can move up and down along the slots 254. Figure 4 and Figure 6The second telescopic motor 32 is detachably screwed and mounted on the front side of the middle part of the front side plate 25, and the telescopic rod 321 extends upward to the empty space 253 at the top of the front side plate 25. A horizontal mounting plate 4 is detachably mounted on the top of the telescopic rod 321, and the rear part of the mounting plate 4 partially extends backward and has a through hole extending left and right. The connecting rod 27 passes through and is accommodated in the through hole of the mounting plate 4 horizontally, and can rotate relative to the mounting plate 4. The flip part 261 of the flip plate 26 is mounted on the mounting plate 4 through the connecting rod 27. A first bevel gear 271 is fixedly installed in the middle of the connecting rod 27, and a front and rear horizontally placed driving motor 5 is detachably installed on the mounting plate 4. The rotating shaft 51 of the driving motor 5 extends toward the connecting rod 27, and a second bevel gear 52 meshing with the first bevel gear 271 is installed at the end of the rotating shaft 51. In this way, the forward or reverse rotation of the rotating shaft 51 of the driving motor 5 drives the first bevel gear 271 through the second bevel gear 52, and drives the connecting rod 27 and the flip part 261 fixedly installed on the connecting rod 27 to rotate forward or reversely relative to the slot 254 around the horizontal axis of the connecting rod 27 through the first bevel gear 271, so that the flip plate 26 flips forward or backward relative to the front side plate 25.

[0027] Before preparing for unloading, the production personnel first move the cardboard unloading and transferring device 2 to the corresponding position in front of the conveyor belt 1, lock the four self-locking wheels 22 to fix the cardboard unloading and transferring device 2 in front of the conveyor belt 1; then, retract the telescopic rods 311 of the two first telescopic motors 31 upward, thereby driving the receiving plate 23 to rise horizontally along the first guide groove 251 relative to the front side plate 25 until the height difference between the upper surface of the receiving plate 23 and the upper surface of the conveyor belt 1 is within a reasonable range, and then extend the telescopic rod 321 of the second telescopic motor 32 upward, thereby driving the mounting plate 4 together with the driving motor 5, the connecting rod 27, and the flip plate 26 installed on the mounting plate 4 to rise along the second guide groove 252 to the top of the front side plate 25, and then make the rotating shaft 51 of the driving motor 5 rotate forwardly, thereby driving the connecting rod 27 and the flip part 261 fixedly installed on the connecting rod 27 to rotate forwardly around the horizontal axis of the connecting rod 27, so that the flip plate 26 flips forward relative to the front side plate 25 until it is flush with the front side plate 25, and the cardboard unloading and transferring device 2 is just like Figure 1 As shown, the preparation work before cutting is completed.

[0028] When unloading is required, the prepared corrugated cardboard (not shown in the figure) is conveyed forward by the conveyor belt 1 until it passes over the front of the conveyor belt 1 and moves to the top of the receiving plate 23, and continues to move forward for a distance under the action of inertia. During this process, the corrugated cardboard is limited and guided by the left and right limiting side plates 24 until it hits the front side plate 25, and then it stops moving forward and falls freely to the receiving plate 23 below under its own gravity, and one corrugated cardboard is unloaded. During this process, the flip plate 26 that has been flipped to be flush with the front side plate 25 acts as an extension of the front side plate 25, and together with the front side plate 25, blocks the cardboard from moving forward. A plurality of prepared corrugated cardboards are conveyed by the conveyor belt 1 one by one and the above-mentioned unloading operation is repeated, and they are stacked one by one on the receiving plate 23. During this process, the telescopic rods 311 of the two first telescopic motors 31 slowly extend downward, driving the receiving plate 23 and the corrugated cardboard unloaded thereon to descend horizontally relative to the front side plate 25 along the first guide groove 251, so that the height difference between the upper surface of the uppermost corrugated cardboard stacked on the receiving plate 23 and the upper surface of the conveyor belt 1 is always maintained within a reasonable range, so that the corrugated cardboard unloaded on the receiving plate 23 will not have a large backward tilt due to the excessive height difference and will not be damaged when freely falling on the receiving plate 23. In addition, since the two first telescopic motors 31 of this embodiment are arranged on the front side surface of the upper part of the front side plate 25 with the telescopic rods 311 facing downward, they do not need to be arranged below the receiving plate 23, so they do not need to occupy the space below the receiving plate 23, so the receiving plate 23 can be lowered lower and the unloading capacity is larger.

[0029] After the unloading is completed, the production personnel make the rotating shaft 51 of the driving motor 5 rotate in the opposite direction, thereby driving the connecting rod 27 and the flip part 261 fixedly installed on the connecting rod 27 to rotate in the opposite direction around the horizontal axis of the connecting rod 27, so that the flip plate 26 is flipped backward relative to the front side plate 25 to the top of the receiving plate 23 and parallel to the receiving plate 23, and then the telescopic rod 321 of the second telescopic motor 32 is retracted downward, which drives the mounting plate 4 together with the driving motor 5, the connecting rod 27, and the flip plate 26 installed on the mounting plate 4 to descend along the second guide groove 252 until the flip plate 26 that has been flipped backward is close to the upper surface of the uppermost corrugated cardboard, and the flip plate 26 is like Figure 5 As shown, the corrugated cardboard between the two is pressed and fixed together with the receiving plate 23. After releasing the four self-locking wheels 22 of the cardboard unloading and transferring device 2, the production staff can pull away the cardboard unloading and transferring device 2 together with the corrugated cardboard thereon and transfer it to other areas for quality inspection. During the transfer process, since the turning plate 26 always presses and fixes the corrugated cardboard with the receiving plate 23, the production staff does not need to hold the corrugated cardboard with their hands all the time, and the transfer operation is convenient and safe.

[0030] The above is only an implementation method of the invention, and does not limit the scope of patent protection. Those skilled in the art can make non-substantial changes or substitutions based on the invention, which still fall within the scope of patent protection.
