DETAILED DESCRIPTION

[0048] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present application.

[0049] In some technologies, there is currently no suitable equipment for transferring and transporting bulk materials packaged in large cartons from a warehouse to a clean room. In order to solve this technical problem, the present application provides a cardboard replacement device. The structures of the various parts of the cardboard replacement device are described below:

[0050] For example, in the production process, it is often necessary to transfer and transport various bulk materials. These bulk materials are usually packaged in large cartons for easy storage and transportation. However, currently in the domestic market, there is still a lack of suitable equipment for efficient and safe transfer and transportation of bulk materials packaged in large cartons from warehouses to clean rooms. Due to the special requirements of the clean room for the environment, the outer packaging cartons in the warehouse usually cannot enter the clean room directly. Therefore, before the materials are taken out of the cartons and transferred to the clean room, the cartons must be dismantled first. Since the bulk materials cannot be directly taken out of the large box, and the lining bags are not enough to bear the internal materials, the cartons cannot be directly dismantled. If the materials are opened separately and transferred, not only is the operation cumbersome, but it is also easy to cause the materials to be contaminated or damaged.

[0051] In response to the above problems, Figure 1 and Figure 2 It can be seen that the present application provides a cardboard replacement device, including: a lifting mechanism 1, a transport mechanism 2; the lifting mechanism 1 is used to lift a large cardboard box surrounded by bulk materials; the transport mechanism 2 is used to transport the material 31 to be dumped to the dumping box 3; the lifting mechanism 1 includes: a mechanism body 11; a fixing frame 12, the fixing frame 12 is partially arranged in the mechanism body 11, and partially arranged outside the mechanism body 11; the fixing frame 12 is as shown in FIG. Figure 3 and Figure 4As shown, the fixed frame 12 is used to install the cylinder 13 and the lifting frame 14; the cylinder 13, the cylinder 13 is arranged outside the main body 11 of the mechanism, and one end of the cylinder 13 is connected to the fixed frame 12; the cylinder 13 is a pneumatic element, and when the cylinder 13 is not ventilated, it will automatically lock to prevent the lifting frame 14 from automatically lifting and lowering and causing accidents; the lifting frame 14, the lifting frame 14 is connected to the other end of the cylinder 13, and the lifting frame 14 is slidably connected to the fixed frame 12 through the cylinder 13; gravity clamps 141 are relatively arranged along the length direction and width direction of the lifting frame 14; the contact part of the gravity clamp 141 and the carton 222 is provided with a silicone material, which on the one hand improves the friction between the gravity clamp 141 and the carton 222, and on the other hand, the silicone material is a soft material that will not cause damage to the carton 222, and prevents the carton 222 from deformation; the size of the gravity clamp 141 can be adjusted, such as Figure 1 and Figure 2 The middle one is a large gravity gripper 141. Figure 3 and Figure 4 In the middle is a small gravity clamp 141; the transport mechanism 2 includes: a forklift 21, and the top of the forklift 21 is clamped with a material 22 to be clamped; the material 22 to be clamped includes: a metal box 221; a carton 222 is arranged in the metal box 221, and the height of the carton 222 is greater than the height of the metal box 221; a ground cover 223, and the ground cover 223 is arranged at the bottom of the carton 222; the carton 222 is arranged with bulk material; wherein, the gravity clamp 141 is used to clamp the carton 222.

[0052] The present application provides a cardboard replacement device, and the transportation process is as follows: first, the carton 222 with the ground cover 223 is moved to the top of the forklift 21, and the ground cover 223 is engaged with the forklift 21, such as Figure 2 As shown, the staff then operates the forklift 21 to transport the carton 222 to the bottom of the gravity clamp 141. After the gravity clamp 141 and the carton 222 are in the same vertical direction, the carton 222 is enclosed by the metal box 221. After the enclosed, the snap device 2212 is locked to enclose the carton 222 and the bulk material into the metal box 221. Then, the gravity clamp 141 is operated to clamp and lift the carton 222. Figure 1 As shown, the material 31 to be discharged is finally transported to the discharge box 3 to wait for the discharge work.

[0053] Depend on Figure 3 and Figure 4It can be seen that the lifting mechanism 1 further includes: a fixing portion 15, which is relatively arranged at the top of the fixing frame 12 along the length direction of the fixing frame 12; a rotating rod 16, both ends of which are rotatably connected to the fixing portion 15; a plurality of sprockets 161 are sleeved on the rotating rod 16; a chain 17, which is sleeved on the sprocket 161, one end of which is connected to the counterweight portion 18, and the other end of which is connected to the lifting frame 14; the counterweight portion 18 is provided with a plurality of counterweight blocks 181. The counterweight portion 18 can be provided to balance the gravity of the lifting frame 14, wherein the counterweight blocks 181 can be added or reduced to the counterweight portion 18 according to the weight of the lifting frame 14 and the process of extracting the carton 222, so as to achieve a balance between the counterweight portion 18 and the lifting frame 14.

[0054] Depend on Figure 1 and Figure 2 It can be seen that a manual valve 111, a pressure regulating valve 112, a pressure gauge 113, and a pneumatic switch 114 are arranged outside the mechanism body 11. Figure 5 The manual valve 111 is shown, and the manual valve 111 is used to open and close the gas to operate the cylinder 13; Figure 5 The pressure regulating valve 112 is shown. By adjusting the pressure regulating valve 112 and observing the pressure value on the pressure gauge 113, the pressure value in the cylinder 13 is kept within the working pressure threshold, thereby preventing the inability to control the lifting frame 14 to rise or move downward due to too low gas pressure, and preventing the cylinder 13 from exploding due to too high pressure. Figure 6 As shown, the pneumatic switch 114 is provided with four buttons, and the buttons are respectively used to control the lifting frame 14 to rise or fall, and control the gravity clamp 141 to enter a clamping state or a releasing state.

[0055] like Figure 5As shown, a filter 115 is also provided on the outside of the mechanism body 11. The main function of the filter 115 is to filter oil, water and other possible tiny impurities in the air. In daily operation, the cardboard replacement equipment needs to be frequently pneumatically operated through the air duct, especially the air flow between the manual valve 111 and the cylinder 13. As time goes by, if the oil, water and other impurities carried in the air enter these key components directly without being filtered, they will gradually accumulate inside the duct and form a blockage. This blockage will not only affect the smoothness of the pneumatic operation, but is also likely to cause the performance of the equipment to decline and even cause failures. Therefore, the existence of the filter 115 is particularly important. Through its efficient filtering function, it ensures that the air entering the equipment is clean and does not contain any impurities that may cause problems. This not only greatly reduces the risk of equipment failure caused by impurity blockage, but also ensures that the equipment can operate stably for a long time, thereby significantly improving the service life of the cardboard replacement equipment.

[0056] like Figure 7 As shown, a first latch 116 is further provided on the outer side of the mechanism body 11, and the first latch 116 is slidably connected to the mechanism body 11; a second latch 117 is provided on the side of the lifting frame 14 close to the mechanism body 11; the first latch 116 is provided with a locking position; when the first latch 116 is in the locking position, the first latch 116 and the second latch 117 are in the same horizontal direction, and a chain penetrates the first latch 116 and the second latch 117, and the lifting frame 14 is fixed to the mechanism body 11. In order to prevent the lifting frame 14 from falling suddenly when not in use or during maintenance, the present application is provided with a first latch 116 and a second latch 117. Since the height of the lifting frame 14 is not fixed, the present application sets the first latch 116 to be slidably connected to the mechanism body 11. The first latch 116 can be slidably connected to the mechanism body 11 through elements such as slide rails, which are not limited here; by sliding the first latch 116 to the same horizontal height as the second latch 117, and locking it after the chain passes through the holes of the first latch 116 and the second latch 117, the lifting frame 14 is prevented from falling suddenly, thereby preventing maintenance personnel from having accidents when repairing the cardboard replacement equipment.

[0057] like Figure 8 As shown, the metal box 221 is provided with a first surface and a second surface, a third surface and a fourth surface which are parallel to each other. The first surface, the third surface, the second surface and the fourth surface are sequentially connected to form the metal box 221; the fourth surface is rotatably connected to the second surface through a hinge device 2211, as shown in FIG. Fig. 9 As shown, the fourth surface is snap-fitted to the first surface via the snap-fit ​​device 2212. Fig.10As shown; a plurality of universal wheels 2213 are provided at the bottom of the metal box 221. The three planes of the metal box 221 are fixedly connected, such as the first plane, the second plane, and the third plane; wherein the fourth plane is rotatably connected to the second plane through a hinge device 2211, and is engaged with the first plane through a snap device 2212. During transportation, the metal box 221 is moved to the forklift 21 through the universal wheels 2213, and the snap device 2212 is opened to wrap the carton 222 inside, and then the snap device 2212 is locked to extract the carton 222, so as to prevent the bulk materials arranged in the carton 222 from being damaged.

[0058] like Figure 8 As shown, the first surface, the second surface, the third surface, and the fourth surface are provided with gaps at the bottom. The gaps are used to provide a place for the forklift 21 to stay, so as to wrap the bulk material therein, wherein the height of the gaps is less than the height of the ground cover 223.

[0059] like Fig.11 As shown, a blocking block 2214 is provided inside the metal box 221 along the length direction and the width direction; the blocking block 2214 partially covers the ground cover 223 in the projection direction of the ground cover 223. The blocking block 2214 is used to block the ground cover 223 when the material 31 to be dumped is dumped, so as to prevent the ground cover 223 from being separated from the metal box 221; wherein, there is a certain gap between the blocking block 2214 and the ground cover 223, which serves as a reserved space when the forklift 21 moves or lifts the ground cover 223.

[0060] like Fig.12 and Fig.13 As shown, the cardboard replacement device is characterized in that it also includes: a dumping box 3, the dumping box 3 is used to place the material 31 to be dumped, and the material 31 to be dumped includes: a metal box 221, and the metal box 221 is provided with bulk materials; a ground cover 223, and the ground cover 223 is arranged at the bottom of the metal box 221; when the material 31 to be dumped is located in the dumping box 3, the fourth side of the metal box 221 is close to the open part of the dumping box 3. The dumping box 3 is used to place the material 31 to be dumped and wait for the dumping work. Generally, when the metal box 221 is arranged in the dumping box 3, the fourth side of the metal box 221 is generally close to the open part of the dumping box 3, so as to avoid the hinge device 2211 and the buckle device 2212 from being scratched and damaged, thereby improving the service life of the metal box 221.

[0061] like Fig.12 and Fig.13As shown, an anti-collision strip 32 is provided on the side of the dump box 3 away from the opening; a limiting rod 33 is provided inside the dump box 3, and both ends of the limiting rod 33 are connected to the two sides of the dump box 3, and both ends of the limiting rod 33 are sleeved with anti-collision rubber 331; guide plates 34 are relatively provided on both sides of the dump box 3, and the guide plates 34 are arranged on the side close to the opening. The anti-collision strip 32 is used to prevent the material 31 to be discharged from the material box 3 from damaging the wall of the material box 3 away from the opening when the material 31 to be discharged enters the material box 3; the limiting rod 33 is used to prevent the material 31 to be discharged from the material box 3 during the discharge operation, and the anti-collision rubber 331 is used to prevent the metal box 221 from damaging the limiting rod 33 when the material 31 to be discharged is discharged; because the universal wheel 2213 arranged on the metal box 221 can move in all directions, in order to prevent the universal wheel 2213 from being stuck on the side wall of the material box 3, the guide plate 34 is arranged to make the universal wheel 2213 move in the same direction before entering the material box 3, so that it can smoothly enter the material box 3.

[0062] The above specific implementation methods further explain in detail the purpose, technical solutions and beneficial effects of the embodiments of the present application.
