Description

Technical Field

[0001] This utility model relates to the field of cardboard box production and processing technology, specifically to a cardboard bending device for corrugated cardboard box production. Background Technology

[0002] Corrugated cardboard box production is a systematic process that integrates material processing, mechanical manufacturing, and process design. It requires multiple processes to transform raw paper into finished cardboard boxes with protective, storage, and transportation functions. In the corrugated cardboard box production process, the cardboard bending device is the key equipment to realize the shaping of cardboard and meet the requirements of cardboard box folding and forming.

[0003] However, existing technologies still have many defects in some similar structures when used in practice. For example, in order to feed the cardboard into the bending area, operators may need to intervene frequently, which not only increases the intensity of manual labor, but may also cause the cardboard to deviate in position due to the instability of manual operation. At the same time, failure to complete the bending as required will directly result in the cardboard forming not conforming to the design specifications of the corrugated carton, making it impossible for the carton to be folded and formed normally, resulting in problems such as size deviation and irregular corners, which in turn affects the subsequent use of the carton and reduces the reliability of the packaging.

[0004] To address the aforementioned problems, the inventors proposed a cardboard bending device for corrugated box production. Utility Model Content

[0005] To address the problems of inconvenience in transporting cardboard into the bending area and inconvenience in bending the cardboard, the purpose of this utility model is to provide a cardboard bending device for corrugated box production.

[0006] To solve the above technical problems, the present invention adopts the following technical solution: a cardboard bending device for corrugated carton production, comprising a fixed frame, a conveying assembly fixedly connected inside the fixed frame, the conveying assembly comprising rotating shafts arranged in a rectangular array, the two ends of the rotating shafts being rotatably connected to the inner walls of the two sides of the fixed frame, a protective shell fixedly connected to one side of the fixed frame, wherein the ends of two of the rotating shafts extend into the protective shell, a first motor is fixedly connected to the upper part of the protective shell, the output end of the first motor extends into the protective shell and is fixedly connected to the upper rotating shaft, wherein gears are fixedly sleeved on the outer surfaces of the two rotating shafts, rollers are fixedly sleeved on the outer surfaces of the rotating shafts, a belt is sleeved between the rollers on the same side, an arc plate is fixedly connected to the inner wall of one side of the fixed frame, a baffle is fixedly connected to the top surface of the fixed frame, an extrusion assembly is fixedly connected to the top surface of the baffle, and a through groove is formed on one side of the top surface of the baffle.

[0007] As a preferred technical solution of this application, the extrusion assembly includes a base, the bottom end of which is fixedly connected to the top end of a baffle. The top end of the base has multiple grooves, and a lead screw is rotatably connected between the inner walls of the two sides of the middle groove. A second motor is fixedly connected to one end of the base, and the output end of the second motor passes through one end of the base and is fixedly connected to one end of the lead screw. A threaded block is threaded onto the outer surface of the lead screw. A slide rail is fixedly connected to the inner walls of both sides of the grooves, and a slider is slidably connected to the outer surface of the slide rail. A sliding plate is fixedly connected to the top ends of the threaded block and the multiple sliders. Multiple support rods are fixedly connected to one end of the sliding plate. A fixing plate is fixedly connected to the top end of the baffle, and a push plate is fixedly connected to one end of the multiple support rods.

[0008] With the above technical solution, when the cardboard needs to be bent, the second motor is started, and its output end drives the lead screw to rotate in the middle slide groove. Since the lead block is threadedly connected to the lead screw and the outer surface of the lead block is in contact with the inner wall of the slide groove, the rotation of the lead screw will cause the lead block to move along the slide groove. At the same time, the sliders in the two slide grooves slide synchronously on the slide rail, which drives the slide plate that is fixed together with the top of the lead block and the slider to move. The slide plate pushes the push plate through the support rod, which can effectively squeeze the cardboard to complete the cardboard bending operation.

[0009] As a preferred technical solution of this application, the outer surfaces of the two gears are meshed and connected to each other, and the two gears are located inside the protective shell.

[0010] The above technical solution can protect the gears with the protective shell.

[0011] As a preferred technical solution of this application, a plurality of guide wheels are rotatably connected to one side of both the arc plate and the baffle.

[0012] Through the above technical solution, the guide wheel plays a guiding role for the cardboard.

[0013] As a preferred technical solution of this application, a guide plate is fixedly connected to the bottom surface of the baffle.

[0014] The above technical solution restricts the conveying direction of the cardboard using a baffle.

[0015] As a preferred technical solution of this application, the outer surface of the wire block is in contact with the inner wall of the groove.

[0016] Using the above technical solution, the wire block moves within the inner wall of the chute.

[0017] As a preferred technical solution of this application, one end of each of the plurality of support rods is movably connected through one end of the fixed plate.

[0018] The above technical solution makes the support rod more stable when it moves.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] The rollers, which are fixedly sleeved on the outer surface of the rotating shaft, rotate. The rollers on the same side are driven by belts, so that multiple rollers and belts can work together to transport the cardboard. During the transport process, the arc plate guides the cardboard, and the baffle restricts the transport direction of the cardboard. The cardboard comes out of the through groove, thus achieving the purpose of effectively transporting the cardboard into the bending area.

[0021] The rotation of the lead screw causes the wire block to move along the slide groove, while the sliders in the slide grooves on both sides slide synchronously on the slide rail, which drives the slide plate, which is fixed together with the top of the wire block and the slider, to move. The slide plate pushes the push plate through the support rod, thereby achieving the purpose of squeezing the cardboard to complete the cardboard bending operation. Attached Figure Description

[0029] The output end of the first motor 303 extends into the protective shell 302 and is fixedly connected to the upper rotating shaft 301. Gears 304 are fixedly sleeved on the outer surfaces of the two rotating shafts 301, and the outer surfaces of the two gears 304 mesh with each other. The two gears 304 are located inside the protective shell 302. Rollers 305 are fixedly sleeved on the outer surfaces of the rotating shafts 301. A belt 306 is sleeved between the rollers 305 on the same side. An arc plate 307 is fixedly connected to the inner wall of one side of the fixed frame 1. A baffle 308 is fixedly connected to the top surface of the fixed frame 1. Multiple guide wheels 309 are rotatably connected to one side of both the arc plate 307 and the baffle 308. An extrusion assembly 2 is fixedly connected to the top surface of the baffle 308. A through groove 310 is opened on one side of the top surface of the baffle 308. A guide plate 311 is fixedly connected to the bottom surface of the baffle 308.

[0030] During the conveying process, the arc plate 307 guides the cardboard, and the baffle 308 restricts the conveying direction of the cardboard. The cardboard comes out of the through groove 310.

[0031] The extrusion assembly 2 includes a base 201, the bottom end of which is fixedly connected to the top end of a baffle 308. Multiple grooves 202 are formed at the top end of the base 201. A lead screw 203 is rotatably connected between the inner walls of the two sides of the middle groove 202. A second motor 204 is fixedly connected to one end of the base 201. The output end of the second motor 204 passes through one end of the base 201 and is fixedly connected to one end of the lead screw 203. A threaded block 205 is threaded onto the outer surface of the lead screw 203. The outer surface of the threaded block 205 is connected to the inner wall of the groove 202. The walls are fitted together, and the inner walls of the two sides of the slide groove 202 are fixedly connected to the slide rail 206. The outer surface of the slide rail 206 is slidably connected to the slider 207. The top of the screw block 205 and the top of the multiple sliders 207 are fixedly connected to the slide plate 208. One end of the slide plate 208 is fixedly connected to the multiple support rods 209. The top of the baffle 308 is fixedly connected to the fixing plate 210. One end of the multiple support rods 209 is movably connected to one end of the fixing plate 210. One end of the multiple support rods 209 is fixedly connected to the push plate 211.

[0032] The slider 207 slides synchronously on the slide rail 206, which drives the slide plate 208, which is fixed together with the top of the slider 207, to move. The slide plate 208 pushes the push plate 211 through the support rod 209.

[0033] The working principle of the corrugated cardboard bending device for corrugated box production in this embodiment is as follows: The cardboard is placed between two belts 306, and the first motor 303 is started. Its output end drives the upper rotating shaft 301 to rotate. Since the gears 304 fixedly sleeved on the outer surfaces of the two rotating shafts 301 located in the protective shell 302 mesh with each other, the upper rotating shaft 301 will drive the lower rotating shaft 301 to rotate synchronously in the opposite direction, thereby causing the rollers 305 fixedly sleeved on the outer surfaces of the rotating shafts 301 to rotate. The rollers 305 on the same side are driven by belts 306, realizing the coordinated operation of multiple rollers 305 and belts 306 to transport the cardboard. During the transport process, the arc plate 307 guides the cardboard, and the baffle 308 restricts the transport direction of the cardboard. The cardboard comes out of the through groove 310, thereby achieving the purpose of effectively transporting the cardboard into the bending area.

[0034] When the cardboard needs to be bent, the second motor 204 is started, and its output end drives the lead screw 203 to rotate in the middle slide groove 202. Since the lead block 205 is threadedly connected to the lead screw 203 and the outer surface of the lead block 205 is in contact with the inner wall of the slide groove 202, the rotation of the lead screw 203 will cause the lead block 205 to move along the slide groove 202. At the same time, the sliders 207 in the two slide grooves 202 slide synchronously on the slide rail 206, which drives the slide plate 208, which is fixed at the top of the lead block 205 and the slider 207, to move. The slide plate 208 pushes the push plate 211 through the support rod 209, thereby achieving the purpose of effectively squeezing the cardboard to complete the cardboard bending operation.
