Description

Technical Field

[0001] This invention relates to the field of packaging technology, and in particular to a cardboard transport and palletizing rack. Background Technology

[0002] Cardboard boxes are commonly used as wrapping materials for goods or as protective outer layers for items. Cardboard boxes are the most widely used packaging products. Depending on the materials used, there are corrugated cardboard boxes, single-layer cardboard boxes, etc. The cardboard box production process involves many transfers. In order to facilitate transfers and meet the requirements of the process, the cardboard used to produce cardboard boxes is folded in half to form double-layer cardboard, so that it can be folded into cardboard boxes later. After the cardboard is folded in half, the cardboard boxes are stacked up for storage or transportation.

[0003] During production and transportation, folded cardboard needs to be stacked. Existing stacking racks generally use simple base trays to stack the cardboard in a space. Since there are no stops on the sides of the base trays, they may tip over or fall during stacking. Some racks weld stops onto the base trays, but this type of base tray takes up a lot of space when stacking, and the number of base trays that can be placed in the same space is small. After the base trays are used up, they need to be taken from other places, which reduces work efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a cardboard transport and stacking rack to solve the problems of existing base trays causing cardboard to tip over and fall when stacked, as well as the space occupied when stacking base trays.

[0005] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

[0006] A cardboard transport palletizing rack, comprising:

[0007] The base has connecting sleeves vertically installed at the four corners of its top surface; a first flipping mechanism is rotatably mounted on the connecting sleeves, and flips along the length of the base, with two sets of the first flipping mechanism arranged opposite each other; a second flipping mechanism is rotatably mounted on the side of the first flipping mechanism, and flips along the width of the first flipping mechanism; the first and second flipping mechanisms are in a folded state when flipped parallel to the base, and in a usable state when flipped perpendicular to the base.

[0008] Furthermore, the first flipping mechanism includes two rotating rods, a first baffle fixedly mounted on the two rotating rods, and a telescopic mechanism telescopically mounted on the rotating rods, with the two rotating rods rotatably mounted on two adjacent connecting sleeves respectively.

[0009] Furthermore, the telescopic mechanism includes a long rod telescopically disposed inside the rotating rod, a second baffle plate clamped on the long rod, an auxiliary plate rotatably disposed at the bottom of the second baffle plate, the bottom of the auxiliary plate being rotatably disposed at the top of the first baffle plate; a circular block is rotatably disposed at the top of the second baffle plate, and an L-shaped rod is rotatably disposed on the circular block, the L-shaped rod being clamped at the top of the long rod.

[0010] Furthermore, the upper part of the connecting sleeve has a groove on one side facing the bottom support, and the other side of the connecting sleeve has a strip groove along the height direction of the connecting sleeve. The bottom of the rotating rod is provided with a fixed shaft that slides in the strip groove.

[0011] Furthermore, a locking element for locking the rotating rod is provided on the side of the connecting sleeve opposite to the groove.

[0012] Furthermore, the locking component includes a pin that passes through the connecting sleeve and a tension spring that is sleeved on the pin. The bottom side of the rotating rod has a pin hole for the pin to engage. One end of the tension spring is fixed to the connecting sleeve, and the other end is fixed to the end of the pin away from the connecting sleeve.

[0013] Furthermore, the second flipping mechanism includes a third baffle rotatably disposed on the side of the first baffle and a fourth baffle rotatably disposed on the top surface of the third baffle, and a quick-connect mechanism is provided between the fourth baffle and the second baffle.

[0014] Furthermore, the quick-connect mechanism includes a support shaft fixedly disposed on the side of the second baffle, two rotating parts rotatably disposed on the support shaft, and a round shaft fixedly disposed on the side of the fourth baffle. The rotating parts are provided with semi-circular grooves, and the semi-circular grooves on the two rotating parts form a circular groove. The round shaft is rotatably connected within the circular groove.

[0015] Furthermore, the rotating component has a through hole, the support shaft is rotatably disposed in the through hole, and a torsion spring is disposed between the through hole and the support shaft.

[0016] Furthermore, the second flipping mechanism is provided in two sets, which are rotatably mounted on the two first flipping mechanisms respectively. The fourth baffle of the two second flipping mechanisms is provided with a pin and a slot respectively, and the pin is engaged in the slot.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The cardboard transport and stacking rack of the present invention, through the coordinated arrangement of the base tray and the first and second flipping mechanisms, ensures that the cardboard can be directly stacked on the base tray after being transported out, reducing manual stacking and improving work efficiency. The coordinated arrangement of the first and second flipping mechanisms can also reduce space occupation in the folded state.

[0019] In addition, through the coordinated arrangement of the rotating rod and the telescopic mechanism, the two first flipping mechanisms can be folded relative to each other when the telescopic mechanism is in the retracted state, ensuring that the space occupied is minimized. Through the coordinated arrangement of the second baffle and the first baffle, the first baffle and the second baffle can be folded, making it convenient for the long rod to retract back into the rotating rod and making folding convenient.

[0020] In addition, the combination of the strip groove and the fixed shaft ensures that the rotating rod can slide within the connecting sleeve, achieving both folding and rotation functions. The combination of the third baffle and the first baffle ensures that the first and third baffles can be folded. The combination of the third baffle and the fourth baffle ensures that they can be folded. The quick-connect mechanism ensures that the fourth baffle and the second baffle can be engaged and rotated, and that the third and fourth baffles can be folded and rotated, thus improving the applicability of the equipment.

[0043] Furthermore, in the description of this invention, unless otherwise explicitly defined, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention in light of the specific circumstances.

[0044] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0045] This embodiment relates to a cardboard transport and palletizing rack, the overall structure of which is as follows: Figure 1 and Figure 8 As shown, it includes a base 1, a first flipping mechanism 3, and a second flipping mechanism 4.

[0046] The base 1 has four vertically arranged connecting sleeves 2 at the four corners of its top surface. The first flipping mechanism 3 is rotatably arranged on the connecting sleeves 2. The first flipping mechanism 3 flips along the length of the base 1. There are two sets of the first flipping mechanism 3 arranged opposite each other. The second flipping mechanism 4 is rotatably arranged on the side of the first flipping mechanism 3. The second flipping mechanism 4 flips along the width of the first flipping mechanism 3. The first flipping mechanism 3 and the second flipping mechanism 4 are folded when they are parallel to the base 1. The first flipping mechanism 3 and the second flipping mechanism 4 are used when they are perpendicular to the base 1.

[0047] It is worth mentioning that the base 1 is rectangular, and the connecting sleeve 2 is fixedly installed on the four corners of the top surface of the rectangular base 1. The two first flipping mechanisms 3 flip relative to each other. In the folded state, the first flipping mechanisms 3 and the second flipping mechanism 4 are parallel to the base 1. At this time, the two first flipping mechanisms 3 also achieve a parallel effect, which can minimize the space occupied after folding. The second flipping mechanism 4 rotates on the first flipping mechanism 3. When the second flipping mechanism 4 and the first flipping mechanism 3 are parallel, it is in the folded state and rotates with the first flipping mechanism 3 to complete the folding of the entire device. In the usage state, the first flipping mechanism 3 and the second flipping mechanism 4 are flipped to be perpendicular to the base 1, which facilitates the stopping of the cardboard. Preferably, the two first flipping mechanisms 3 are located in the width direction of the rectangular base 1, and the second flipping mechanism 4 is located in the length direction of the rectangular base 1. This ensures that after the cardboard enters the base 1, the first flipping mechanism 3 and the second flipping mechanism 4 can stop the cardboard and improve the neatness of the cardboard.

[0048] Based on the above overall introduction, this embodiment presents an exemplary structure of a cardboard transport palletizing rack, such as... Figure 2 and Figure 3As shown, the first flipping mechanism 3 includes two rotating rods 301, a first baffle 302 fixedly mounted on the two rotating rods 301, and a telescopic mechanism 303 telescopically mounted on the rotating rods 301. The two rotating rods 301 are respectively rotatably mounted on two adjacent connecting sleeves 2. A groove 304 is provided on the upper part of the connecting sleeve 2 facing the inside of the base 1, and a strip groove 305 is provided on the other side of the connecting sleeve 2 along the height direction of the connecting sleeve 2. A fixed shaft 306 is provided at the bottom of the rotating rod 301, which slides within the strip groove 305.

[0049] Specifically, the fixed shaft 306 can slide within the strip groove 305. When the rotating rod 301 is inserted into the connecting sleeve 2, the fixed shaft 306 is located at the bottom of the strip groove 305. At this time, the rotating rod 301 is perpendicular to the base 1. When the fixed shaft 306 is located at the top of the strip groove 305, it can rotate. The size of the groove 304 and the rotating rod 301 are matched, that is, the rotating rod 301 can rotate into the groove 304 to ensure that the rotating rod 301 can rotate to be parallel to the base 1. At this time, it is in a folded state. The first baffle 302 is fixedly installed in the two rotating rods 301. When the rotating rod 301 rotates, the first baffle 302 can rotate with it. The function of the first baffle 302 is to prevent the cardboard from sliding out of the base 1 after entering the base 1. The telescopic mechanism 303 can adjust the height of the first flipping mechanism 3 to ensure that the cardboard can be stacked to different heights according to the height of the telescopic mechanism 303.

[0050] As a preferred option, such as Figure 4 , Figure 7 and Figure 9 As shown, in this embodiment, the telescopic mechanism 303 includes a long rod 3031 telescopically disposed inside the rotating rod 301, a second baffle 3032 snapped onto the long rod 3031, and an auxiliary plate 3033 rotatably disposed at the bottom of the second baffle 3032. The bottom of the auxiliary plate 3033 is rotatably disposed at the top of the first baffle 302. Specifically, a through groove is formed in the length direction of the rotating rod 301, and the long rod 3031 is slidably disposed in the through groove. There is a certain friction between the long rod 3031 and the through groove. A friction pad can also be provided between the long rod 3031 and the through groove to ensure that the long rod 3031 will not slip after rising. The function of the auxiliary plate 3033 is to leave a space between the first baffle 302 and the second baffle 3032 when the folded state is such that the second flipping mechanism 4 can be placed in this space.

[0051] Furthermore, a circular block 5 is rotatably mounted on the top of the second baffle 3032, and an L-shaped rod 6 is rotatably mounted on the circular block 5. The L-shaped rod 6 is engaged with the top of the long rod 3031. The circular block 5 can drive the L-shaped rod 6 to rotate, ensuring that when the L-shaped rod 6 is not in use, it can rotate to any position without affecting the folding of the second baffle 3032. The L-shaped rod 6 can be hung on the long rod 3031, ensuring that the second baffle 3032 will not separate from the long rod 3031. In addition, when the L-shaped rod 6 is engaged with the long rod 3031, it has an interference fit with the long rod 3031 to ensure stability.

[0052] As a preferred option, such as Figure 3 As shown, in this embodiment, a locking member 307 for locking the rotating rod 301 is provided on the side of the connecting sleeve 2 away from the groove 304. The locking member 307 includes a pin 3071 passing through the connecting sleeve 2 and a tension spring 3072 sleeved on the pin 3071. A pin hole 3073 for the pin 3071 to engage is provided on the bottom side of the rotating rod 301. One end of the tension spring 3072 is fixed to the connecting sleeve 2, and the other end is fixed to the end of the pin 3071 away from the connecting sleeve 2.

[0053] It should be noted that the locking component 307 can fix the rotating rod 301 inside the connecting sleeve 2. Its main function is to prevent the rotating rod 301 from coming out of the connecting sleeve 2 when the base support 1 needs to be hung. Specifically, the pin 3071 extends and retracts on the connecting sleeve 2. When the pin hole 3073 and the pin 3071 are concentric, the pin 3071 can be inserted into the pin hole 3073 due to the tension of the tension spring 3072. When it is necessary to remove the rotating rod 301 from the connecting sleeve 2, simply pull the pin 3071. The pin 3071 will disengage from the pin hole 3073, and the rotating rod 301 can be pulled out directly. At this time, the pin 3071 abuts against the arc-shaped surface at the bottom of the rotating rod 301.

[0054] As a preferred option, such as Figure 4 As shown, the second flipping mechanism 4 in this embodiment includes a third baffle 401 rotatably disposed on the side of the first baffle 302 and a fourth baffle 402 rotatably disposed on the top surface of the third baffle 401. A quick-connect mechanism 403 is provided between the fourth baffle 402 and the second baffle 3032. It should be noted that a rotating cylinder and a rotating shaft are respectively provided between the third baffle 401 and the first baffle 302, so that the third baffle 401 can rotate on the first baffle 302. The fourth baffle 402 is mainly configured to cooperate with the telescopic mechanism 303. When the telescopic mechanism 303 extends, the fourth baffle 402 can be rotated to the top of the third baffle 401 to ensure that the cardboard can be stacked at different heights. The quick-connect mechanism 403 can conveniently fix the fourth baffle 402 on the second baffle 3032.

[0055] As a preferred option, such as Figure 5As shown, in this embodiment, the quick-connect mechanism 403 includes a support shaft 4031 fixedly mounted on the side of the second baffle 3032, two rotating parts 4032 rotatably mounted on the support shaft 4031, and a circular shaft 4033 fixedly mounted on the side of the fourth baffle 402. The rotating parts 4032 have semi-circular grooves 4034, which together form a circular groove. The circular shaft 4033 is rotatably connected within this circular groove. The rotating parts 4032 have through holes 4035, and the support shaft 4031 is rotatably mounted within these through holes. A torsion spring 4036 is provided between the through hole 4035 and the rotating shaft.

[0056] Specifically, the support shaft 4031 is fixedly mounted on the second baffle 3032, and the two rotating parts 4032 rotate at the upper and lower ends of the support shaft 4031 respectively. A circular hole is fitted onto the support shaft 4031, and one end of the torsion spring 4036 is fixedly mounted on the support shaft 4031, while the other end is fixedly mounted inside the circular hole. This arrangement ensures that the two rotating parts 4032 can always remain in contact. The circular shaft 4033 is rotatably mounted in the two semi-circular grooves 4034. The circular groove formed by the two semi-circular grooves 4034 ensures circumferential rotation. When the second flipping mechanism 4 is not needed, it can be rotated to open. Since the two rotating parts 4032 can be opened, when the fourth baffle 402 is needed, the fourth baffle 402 can be rotated to engage the circular shaft 4033 in the circular groove. Conversely, separating the two rotating parts 4032 allows the circular shaft 4033 to be removed from the circular groove.

[0057] As a preferred option, such as Figure 6 As shown, this embodiment has two sets of second flipping mechanisms 4, which are rotatably mounted on the two first flipping mechanisms 3 respectively. The fourth baffle 402 of each of the two second flipping mechanisms 4 is provided with a pin 404 and a slot 405, with the pin 404 engaging within the slot 405. Specifically, the arrangement of the two second flipping mechanisms 4 ensures that the width of each second flipping mechanism 4 is equal to or less than the width of the first flipping mechanism 3, ensuring that the second flipping mechanism 4 does not affect the folding state of the first flipping mechanism 3. The pins 404 and slots 405 ensure that when the two second flipping mechanisms 4 are parallel, they can be fixed in place to prevent further flipping.

[0058] In this embodiment, the cardboard transport and stacking rack, through the cooperation of the base tray 1 and the first flipping mechanism 3 and the second flipping mechanism 4, ensures that the cardboard can be directly stacked on the base tray 1 after being transported out, reducing manual stacking and improving work efficiency. The cooperation of the first flipping mechanism 3 and the second flipping mechanism 4 can also reduce the space occupied in the folded state.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
