Description

Technical Field

[0001] This utility model relates to the technical field of box collecting machines, and in particular to an automatic box collecting machine suitable for paper boxes of different sizes. Background Technology

[0002] In the process of processing and packaging folded cardboard boxes, we need to use an automatic box collecting machine. Existing box collecting machines are usually automated equipment installed at the end of the production line to collect the flat cardboard boxes that are transported there.

[0003] Existing automatic box collecting machines are difficult to adapt to folded cardboard boxes of different sizes during use. The boxes collecting machines usually have limiting structures on both sides to regulate the position of the cardboard boxes and prevent them from being stacked haphazardly. However, the limiting structures are difficult to adjust for different sizes of cardboard boxes. Because the limiting structures cannot adapt to different sizes of cardboard boxes, when processing small-sized cardboard boxes, the excessively large limiting gaps will cause the cardboard boxes to still have a large amount of room to move during the stacking process, making it difficult to form a neat arrangement and increasing the difficulty of subsequent sorting. Utility Model Content

[0004] The purpose of this invention is to provide an automatic box collecting machine suitable for paper boxes of different sizes, so as to solve the problems mentioned in the background art.

[0005] The technical solution adopted in this utility model is:

[0006] An automatic box collecting machine suitable for paper boxes of different sizes includes a machine body, with support legs fixedly connected to the bottom of the machine body, a conveyor belt provided at the top of the machine body, a baffle fixedly connected to one end of the machine body, a connecting plate fixedly connected to the bottom of the machine body, a dual-axis servo motor fixedly connected to the top of the connecting plate, transmission rods fixedly connected to the output ends on both sides of the dual-axis servo motor, a lead screw fixedly connected to one side of the transmission rod, a moving block threadedly connected to the surface of the lead screw, a push plate fixedly connected to the surface of the moving block, and a clamping plate fixedly connected to one side of the push plate.

[0007] In some embodiments, an outer cylinder is fixedly connected to the side of the clamping plate near the conveyor belt, a force-bearing block is slidably connected to the inner wall of the outer cylinder, a spring is fixedly connected between one end of the force-bearing block and the inner wall of the outer cylinder, an extension block is fixedly connected to one side of the clamping plate, an arc-shaped plate is fixedly connected to one end of the extension block, a bonding plate is fixedly connected to one end of the arc-shaped plate, and the back of the bonding plate is fixedly connected to the force-bearing block.

[0008] In some embodiments, a first drive roller is rotatably connected to one end of the inner side of the conveyor belt, and an output end of a motor is rotatably connected to one end of the first drive roller. A second drive roller is rotatably connected to one end of the conveyor belt away from the first drive roller, and the two ends of the second drive roller and the first drive roller are rotatably connected to the two sides of the machine body.

[0009] In some embodiments, a support block is rotatably connected to the surface of the transmission rod, and a through hole is provided at the center of the support block. The lead screw passes through the through hole and is rotatably connected to a bearing on the inner wall of the through hole.

[0010] In some embodiments, a limiting block is fixedly connected to the inner side of the two push plates, a limiting groove is fixedly connected to both ends of the bottom of the machine body, the inner wall of the limiting groove is slidably connected to the limiting block, and the support block is fixedly connected to the machine body.

[0011] In some embodiments, the radius of curvature of the arc-shaped plate gradually decreases from one end near the extension block toward the bonding plate.

[0012] In some embodiments, the two lead screws have the same thread lead and opposite rotation directions, so that when the dual-axis servo motor is driven, the moving blocks on both sides can move synchronously towards or away from each other.

[0013] In some embodiments, the contact surface of the bonding plate is provided with an elastic rubber layer.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (i) By adjusting the spacing between the clamps, the cardboard boxes are positioned to avoid the problem of scattered stacking caused by the inability of traditional positioning structures to adapt to different sizes of cardboard boxes. At the same time, the synergistic effect of the baffles and clamps effectively limits the cardboard boxes in all directions, ensuring the stability and neatness of the cardboard boxes during the box-collecting process.

[0016] (ii) The buffer structure composed of the outer cylinder, the force-bearing block and the spring can effectively prevent the clamping force of the clamping plate on the paper box from being too large and damaging the paper box. At the same time, the design of the arc plate and the bonding plate can make the clamping more stable, adapt to paper boxes of different shapes, improve the reliability of box collection and the protection of the paper box.

Therefore, they should not be construed as limitations on this utility model.

[0026] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0027] Given that current automatic cardboard box collecting machines are difficult to adapt to different sizes of folded cardboard boxes during use, the machines typically have limiting structures on both sides to regulate the position of the cardboard boxes and prevent them from being stacked haphazardly. However, these limiting structures are difficult to adjust for different sizes of cardboard boxes. Because the limiting structures cannot adapt to different sizes of cardboard boxes, when processing small-sized cardboard boxes, the excessively large limiting gaps will cause the cardboard boxes to still have a large amount of room to move during the stacking process, making it difficult to form a neat arrangement and increasing the difficulty of subsequent sorting.

[0028] like Figure 1-6 As shown, this utility model embodiment provides an automatic box collecting machine suitable for paper boxes of different sizes, including a machine body 1, a support leg 101 fixedly connected to the bottom of the machine body 1, a conveyor belt 102 provided at the top of the machine body 1, a baffle 103 fixedly connected to one end of the machine body 1, a connecting plate 2 fixedly connected to the bottom of the machine body 1, a dual-axis servo motor 201 fixedly connected to the top of the connecting plate 2, transmission rods 202 fixedly connected to the output ends on both sides of the dual-axis servo motor 201, a lead screw 203 fixedly connected to one side of the transmission rod 202, a moving block 204 threadedly connected to the surface of the lead screw 203, a push plate 205 fixedly connected to the surface of the moving block 204, and a clamping plate 206 fixedly connected to one side of the push plate 205.

[0029] The machine body 1 is installed in the production line, serving as a conveyor track at the end of the production line. It continuously conveys folded cardboard boxes vertically onto the conveyor belt 102 on the machine body 1 for subsequent collection and sorting by the box collecting machine. The boxes are then conveyed via the conveyor belt 102 to the baffle 103. The baffle 103 at the end of the conveyor belt 102 prevents the movement of the cardboard boxes, facilitating collection by workers. The conveyor belt 102 is existing technology and will not be described in detail here.

[0030] When the cardboard box arrives on the conveyor belt 102, the dual-axis servo motor 201 starts, and its output ends on both sides drive the lead screw 203 to rotate. Since the lead screw 203 is threadedly connected to the moving block 204, the moving block 204 begins to move under the rotation of the lead screw 203, which in turn drives the push plate 205 to move. The push plate 205 then drives the clamping plate 206 to move. The clamping plates 206 on both sides move towards each other according to the size of the cardboard box. Based on the actual size of the cardboard box measured by the scale, the distance between the clamping plates 206 is determined according to the size, thereby limiting the cardboard boxes of different sizes (the thread direction of the lead screw 203 is explained later). After the clamping plates 206 on both sides complete the distance adjustment and realize the limitation of cardboard boxes of different sizes, when the cardboard box continues to move on the conveyor belt 102, its two sides are steadily limited within a certain range by the clamping plates 206, and there will be no large left and right swaying or deviation from the predetermined position. When the cardboard box moves with the conveyor belt 102 to a position close to the baffle 103, the baffle 103 acts as a front limiter for the cardboard box, forming a complete limiting space together with the side clamps 206, accurately fixing the cardboard box in the appropriate position, and preparing for subsequent stacking, collection and other operations.

[0031] By adjusting the spacing of the clamps 206, the boxes are positioned to avoid the problem of scattered stacking caused by the inability of traditional positioning structures to adapt to different sized boxes. At the same time, the synergistic effect of the baffles 103 and the clamps 206 effectively limits the boxes in all directions, ensuring the stability and neatness of the boxes during the stacking process.

[0032] Furthermore, an outer cylinder 305 is fixedly connected to the side of the clamping plate 206 near the conveyor belt 102. A force-bearing block 303 is slidably connected to the inner wall of the outer cylinder 305. A spring 304 is fixedly connected between one end of the force-bearing block 303 and the inner wall of the outer cylinder 305. An extension block 3 is fixedly connected to one side of the clamping plate 206. An arc-shaped plate 301 is fixedly connected to one end of the extension block 3. An adhesive plate 302 is fixedly connected to one end of the arc-shaped plate 301. The back of the adhesive plate 302 is fixedly connected to the force-bearing block 303.

[0033] When the bonding plate 302 contacts the cardboard box, the external force pushes the force-bearing block 303 to compress the spring 304, while the deformation of the arc plate 301 adapts to different box shapes. The extension block 3 acts as a force transmission medium, converting the rigid thrust of the clamping plate 206 into the flexible clamping of the bonding plate 302.

[0034] The bonding plate 302 is flat and made of aluminum alloy with an elastic rubber layer on the surface. It is a flexible clamping component that directly contacts the surface of the cardboard box, providing cushioning protection and adapting to different box shapes. The force-bearing block 303 is cylindrical and made of aluminum alloy. It receives the thrust of the clamping plate 206 and transmits it to the spring 304. The outer cylinder 305 is a hollow cylinder made of aluminum alloy and serves as the mounting base for the spring 304.

[0035] The buffer structure composed of outer cylinder 305, force block 303 and spring 304 can effectively prevent the clamping force of clamping plate 206 on paper box from being too large and damaging the paper box. At the same time, the design of arc plate 301 and bonding plate 302 can make the clamping more stable, adapt to paper boxes of different shapes, improve the reliability of box collection and the protection of paper box.

[0036] Furthermore, a first drive roller 4 is rotatably connected to one end of the inner side of the conveyor belt 102, and the output end of the motor 401 is rotatably connected to one end of the first drive roller 4. A second drive roller 402 is rotatably connected to one end of the conveyor belt 102 away from the first drive roller 4. The two ends of the second drive roller 402 and the first drive roller 4 are rotatably connected to the two sides of the machine body 1.

[0037] The electric motor 401 serves as the power source, and its output drives the first drive roller 4 to rotate. The first drive roller 4 contacts the inner side of the conveyor belt 102, driving the conveyor belt 102 to rotate through friction. The other end of the conveyor belt 102 is connected to the second drive roller 402, which also rotates under the drive of the conveyor belt 102, thus achieving stable operation of the conveyor belt 102 and transporting the cardboard box from one end to the other. This ensures that the conveyor belt 102 can operate smoothly and continuously, meeting the needs of cardboard box transportation.

[0038] Furthermore, a support block 207 is rotatably connected to the surface of the transmission rod 202. The support block 207 has a through hole at its center. The lead screw 203 passes through the through hole and is rotatably connected to the bearing on the inner wall of the through hole. The support block 207 is fixedly connected to the machine body 1.

[0039] The lead screw 203 passes through the through hole in the center of the support block 207 and is rotatably connected to the bearing on the inner wall of the through hole. The bearing reduces the friction between the lead screw 203 and the support block 207, allowing the lead screw 203 to rotate smoothly. At the same time, the support block 207 is fixed in a suitable position to prevent the lead screw 203 from shaking or shifting during rotation, thus ensuring the accuracy and stability of the movement of the moving block 204 on the lead screw 203.

[0040] Furthermore, the inner sides of the two push plates 205 are fixedly connected to the limiting blocks 501, and the two ends of the bottom of the body 1 are fixedly connected to the limiting grooves 5, with the inner wall of the limiting grooves 5 slidably connected to the limiting blocks 501.

[0041] The limiting block 501 moves synchronously with the push plate 205 and slides along the inner wall of the limiting groove 5. The guide surface of the limiting groove 5 constrains the movement trajectory of the limiting block 501 and prevents the push plate 205 from twisting.

[0042] Furthermore, the radius of curvature of the arc plate 301 gradually decreases from the end near the extension block 3 toward the bonding plate 302.

[0043] When limiting the cardboard box, this curvature design allows the curved plate 301 to better fit the shape of the cardboard box. The curved plate 301 can increase the contact area between the bonding plate 302 and the cardboard box through its own curvature change, making the clamping more stable.

[0044] Furthermore, the two lead screws 203 have the same thread lead and opposite rotation directions, so that when the dual-axis servo motor 201 drives, the moving blocks 204 on both sides can move synchronously towards or away from each other.

[0045] The left-hand and right-hand lead screws 203 rotate synchronously under the drive of the dual-axis servo motor 201, so that the two moving blocks 204 on both sides obtain linear motion in opposite directions but at the same speed, while the paper box can be restricted to the middle of the conveyor belt 102.

[0046] Furthermore, the contact surface of the bonding plate 302 is provided with an elastic rubber layer. The elastic rubber layer can protect the surface of the cardboard box from scratches.

[0047] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
