Description

Technical Field

[0001] The utility model relates to the field of packaging box production equipment, and more specifically, to an indentation device. Background Art

[0002] Corrugated boxes are a common form of outer packaging used in the packaging industry and are widely used in shipping. With the booming logistics industry in recent years, demand for packaging boxes has steadily increased. During the production process, the cardboard is typically cut to the desired size and then creased using a creasing device to create bend marks, allowing the cardboard to be bent along these creases to form a box.

[0003] The creasing mechanism in conventional packaging carton production equipment typically only moves horizontally on guide rails to accommodate the production of different carton sizes, without any lifting function. If a paper jam or malfunction occurs during production, maintenance becomes difficult after the machine is shut down. Manual paper removal is difficult due to the creasing wheel being stuck, which can cause secondary damage to the cardboard during removal, making it inconvenient. Furthermore, vertically fixed creasing mechanisms cannot accommodate different cardboard thicknesses, hindering production expansion.

[0004] It can be seen that there are still many technical problems in the existing technology that need to be improved. Utility Model Content

[0005] The main purpose of the utility model is to provide an indentation device, aiming to solve the technical problem of indentation devices in the prior art being inconvenient to use.

[0006] To achieve the above-mentioned purpose, the utility model proposes an indentation device, including a fixed seat, to which an indentation frame is rotatably connected, and to which an indentation wheel is rotatably connected; a first clamping hole is provided on the fixed seat, and a second clamping hole is provided on the indentation frame; a positioning pin is detachably installed on the fixed seat, and the positioning pin passes through the first clamping hole and the second clamping hole to fix the indentation frame.

[0007] The present invention adopts the above-mentioned structure, so that the creasing wheel installed on the creasing frame can rotate with the creasing frame around the connection point between the creasing frame and the fixed seat within a certain angle. In other words, the creasing frame drives the creasing wheel to swing, and it can be achieved without disassembling the creasing device. By pulling out the positioning pin and swinging the creasing wheel device, the creasing wheel can be quickly separated from the cardboard surface, thereby making it easier to remove the cardboard. The positioning pin structure can easily fix the creasing frame, allowing the creasing wheel to work stably without swinging due to friction, thereby causing displacement that affects the efficiency and quality of creasing. By removing the positioning pin, the creasing frame can easily swing to lift the creasing wheel, making it convenient and quick to use.

[0008] Preferably, the indentation device further includes a wheel axle, which includes a clamping portion, a connecting portion, and a fixing portion. A first through-hole is provided on the fixed seat, and a second through-hole is provided on the indentation frame. The diameters of the clamping portion and the fixing portion are larger than the apertures of the first through-hole and the second through-hole, and the diameter of the connecting portion is smaller than the apertures of the first through-hole and the second through-hole. The clamping portion and the connecting portion are integrally formed, and the connecting portion passes through the first through-hole and the second through-hole to be fixedly connected to the fixing portion. Using a detachable wheel axle to connect the fixed seat and the indentation frame makes the indentation frame easier to disassemble and assemble, while maintaining flexible rotation.

[0009] Preferably, a first groove for accommodating the clamping portion is provided on one side of the fixed seat close to the clamping portion, and a second groove for accommodating the fixing portion is provided on one side of the indentation frame close to the fixing portion. The two ends of the wheel axle are well hidden inside the fixed seat and the indentation frame, reducing the protrusions on the surface of the device.

[0010] Preferably, the indentation device further includes a rotating shaft. A third through-hole is provided on the indentation frame, and one end of the rotating shaft passes through the third through-hole, and the other end of the rotating shaft is fixedly connected to the indentation wheel. The indentation wheel is rotatably connected to the indentation frame through the rotating shaft.

[0011] Preferably, the rotating shaft includes an integrally formed first roller, a second roller, and a third roller. The first roller and the third roller are respectively located on both sides of the second roller. A fourth through-hole is provided on the indentation wheel. The diameter of the first roller is smaller than the aperture of the third through-hole, the diameter of the third roller is smaller than the aperture of the fourth through-hole, and the diameter of the second roller is larger than the apertures of the third through-hole and the fourth through-hole. The first roller passes through the third through-hole, the third roller passes through the fourth through-hole, and the second roller is fixedly connected to the indentation wheel. The third roller of the rotating shaft passes through the fourth through-hole of the indentation wheel, facilitating the installation and fixation of the indentation wheel.

[0012] Preferably, the indentation frame includes a first arm frame and a second arm frame. The first arm frame and the second arm frame are fixedly connected by bolts; the first arm frame is rotatably connected to the fixed seat, the second arm frame is rotatably connected to the indentation wheel, and the second card hole is provided on the first arm frame.

[0013] Preferably, a strip-shaped first screw hole is provided on the first boom, and a second screw hole is provided on the second boom. The long side of the first screw hole is arranged radially along the rotation direction of the indentation frame. The first boom and the second boom are fixedly connected by screws passing through the first screw hole and the second screw hole. Through the mutual cooperation of the first screw hole, the second screw hole and the screws, the relative positions of the first boom and the second boom can be changed radially during the swing movement of the indentation frame, so as to realize the overall elongation or shortening of the indentation frame, and the distance between the indentation wheel and the cardboard can be adjusted, so that the indentation device can be adapted to cardboard of different thicknesses.

[0014] Preferably, a first keyway is provided on the rear side of the first boom, and a second keyway is provided on the front side of the second boom. The upper end of the second keyway is open. Both the first keyway and the second keyway are arranged radially along the rotation direction of the indentation frame and partially overlap. The cooperation of the key pins can prevent the first boom and the second boom from generating lateral displacement and facilitate the longitudinal adjustment of the relative positions of the first boom and the second boom.

[0015] Preferably, the indentation device further includes a side plate. The side plate is connected to the fixed seat. One end of the side plate extends horizontally outwards to form a limiting plate. The limiting plate includes a guiding portion and a limiting portion. The guiding portion is inclined to the plane where the limiting portion is located, and the included angle between the guiding portion and the limiting portion is an obtuse angle. The limiting portion is provided with a notch for accommodating the indentation wheel. The structure of the limiting plate makes it easier for the cardboard to enter the lower part of the indentation device for indentation processing, which is beneficial to the smoother introduction of the cardboard into the longitudinal cutting process after transverse cutting and is not easy to jam.

[0028] Example

[0029] Reference Figure 1 , an indentation device, comprising a fixed seat 1, a fixing seat 1 is rotatably connected to an indentation frame 2, and the indentation frame 2 is rotatably connected to an indentation wheel 3; Figure 2 As shown, a first locking hole 101 is provided on the fixing base 1, a second locking hole 201 is provided on the indentation frame 2, and a positioning pin 4 is detachably installed on the fixing base 1, and the positioning pin 4 passes through the first locking hole 101 and the second locking hole 201 to fix the indentation frame 2. The indentation frame 2 is rotatably connected to the fixing base 1, and the indentation frame 2 is fixed by the positioning pin 4, so that the indentation wheel 3 can work stably when in the working state and will not be displaced due to friction. In this embodiment, the positioning pin 4 adopts an automatic reset elastic positioning pin. The positioning pin 4 can be ejected by pressing, thereby achieving the purpose of moving the indentation frame 2. Pressing it back to the initial position again can lock the indentation frame 2. According to actual conditions, ordinary latch-type positioning pins can also be used. The creasing frame 2 is rotatably connected to the fixing base 1, so that the creasing frame 2 can swing around the connection point, thereby driving the creasing wheel 3 to rotate within a certain angle, so that the creasing wheel 3 can quickly separate from the cardboard surface. When paper jams or maintenance is required, the creasing frame 2 can be swung to move the creasing wheel 3 away from the cardboard, so that the cardboard can be easily removed without causing secondary damage, which is easy to use.

[0030] In this embodiment, Figures 1-2As shown in the figure, the indentation device further includes a wheel axle 5. The wheel axle 5 includes a clamping portion 51, a connecting portion 52, and a fixing portion 53. A first through hole 102 is provided on the fixing seat 1, and a second through hole 202 is provided on the indentation frame 2. The diameters of the clamping portion 51 and the fixing portion 53 are greater than the apertures of the first through hole 102 and the second through hole 202, and the diameter of the connecting portion 52 is smaller than the apertures of the first through hole 102 and the second through hole 202. The clamping portion 51 and the connecting portion 52 are integrally formed, and the connecting portion 52 passes through the first through hole 102 and the second through hole 202 and is fixedly connected to the fixing portion 53. By setting the diameter of the connecting portion 52 to be slightly smaller than the apertures of the first through hole 102 and the second through hole 202, the indentation frame 2 can rotate flexibly and will not generate excessive radial displacement during the rotation process. The connecting portion 52 and the fixing portion 53 can be fixed by the cooperation of screws and screw holes, which is convenient for disassembly, or other well-known connection methods can also be used for fixed connection.

[0031] In some specific embodiments, as Figure 3 shown, a first groove 103 for accommodating the clamping portion 51 is provided on one side of the fixing seat 1 close to the clamping portion 51, as Figure 2 shown, a second groove 203 for accommodating the fixing portion 53 is provided on one side of the indentation frame 2 close to the fixing portion 53. This facilitates the two ends of the wheel axle 5 to be respectively embedded into the fixing seat 1 and the indentation frame 2, reducing the protrusions on the surface of the device.

[0032] In this embodiment, as Figures 1-2 shown, the indentation device further includes a rotating shaft 6. A third through hole 204 is provided on the indentation frame 2, and one end of the rotating shaft 6 passes through the third through hole 204, and the other end of the rotating shaft 6 is fixedly connected to the indentation wheel 3. In some preferred embodiments, as Figure 2 shown, the rotating shaft 6 includes a first roller 61, a second roller 62, and a third roller 63 that are integrally formed. The first roller 61 and the third roller 63 are respectively located on both sides of the second roller 62. A fourth through hole 301 is provided on the indentation wheel 3. The diameter of the first roller 61 is slightly smaller than the aperture of the third through hole 204, the diameter of the third roller 63 is slightly smaller than the aperture of the fourth through hole 301, and the diameter of the second roller 62 is greater than the apertures of the third through hole 204 and the fourth through hole 301. During installation, the first roller 61 passes through the third through hole 204, the third roller 63 passes through the fourth through hole 301, and the second roller 62 is fixedly connected to the indentation wheel 3. The second roller 62 and the indentation wheel 3 can be fixed by screws. Bearings can also be provided on the rotating shaft 6 to make the rotation efficiency of the indentation wheel 3 higher. By providing the third roller 63 on the rotating shaft 6 and passing the third roller 63 through the fourth through hole 301 of the indentation wheel 3, it is convenient to fixedly install the indentation wheel 3.

[0033] In practical applications, the rotational connections between the fixed seat 1 and the indentation frame 2, as well as between the indentation frame 2 and the indentation wheel 3, can also adopt other well-known rotational connection structures. The structures of the wheel shaft 5 and the rotating shaft 6 adopted in this embodiment are only for exemplary display.

[0034] In some specific embodiments, such as Figures 1-2 shown, the indentation frame 2 includes a first arm 21 and a second arm 22. The first arm 21 and the second arm 22 are fixedly connected by bolts (not shown in the figure); the first arm 21 is rotationally connected to the fixed seat 1. That is to say, the second through hole 202 is provided on the first arm 21, and the first arm 21 and the fixed seat 1 are rotationally connected by the wheel shaft 5; the second arm 22 is rotationally connected to the indentation wheel 3. That is to say, the third through hole 204 is provided on the second arm 22, and the second arm 22 and the indentation wheel 3 are rotationally connected by the rotating shaft 6; the second locking hole 201 is provided on the first arm 21. In some preferred embodiments, such as Figure 2 shown, a strip-shaped first screw hole 211 is provided on the first arm 21, and a second screw hole 221 is provided on the second arm 22. The long side of the first screw hole 211 is arranged radially along the rotation direction of the indentation frame 2. The first arm 21 and the second arm 22 are fixedly connected by bolts (not shown in the figure) passing through the first screw hole 211 and the second screw hole 221. The first screw hole 211 is longitudinally arranged, so that after the bolt passes through the second screw hole 221, it can longitudinally displace in the first screw hole 211, thereby adjusting the relative position between the second arm 22 and the first arm 21, and further affecting the distance between the indentation wheel 3 and the cardboard, so as to adapt to cardboard of different thicknesses. At least two groups of the first screw hole 211 and the second screw hole 221 can be provided to facilitate the installation stability of the indentation wheel 3. In practical applications, the first arm 21 and the second arm 22 can also adopt well-known connection structures to achieve the above-mentioned purpose of adjustable relative position, such as using a slide rail and other structures.

[0035] In some preferred embodiments, such as Figure 2 and Figure 4 shown, a first keyway 212 is provided on the rear side of the first arm 21, and a second keyway 222 is provided on the front side of the second arm 22. The upper end of the second keyway 222 is open. The first keyway 212 and the second keyway 222 are both arranged radially along the rotation direction of the indentation frame 2 and partially overlap. The first arm 21 and the second arm 22 can be limited by using a key pin (not shown in the figure) to avoid lateral displacement, and it is more stable when adjusting the relative position between the first arm 21 and the second arm 22.

[0036] In some specific embodiments, such as Figure 1 、 Figure 2 and Figure 5As shown, the indentation device further includes a side plate 71, and the side plate 71 is connected to the fixed seat 1. In this embodiment, screw fixed connection is adopted, and other well-known connection methods can also be used. One end of the side plate 71 extends horizontally outwards to form a limiting plate 72. The limiting plate 72 includes a guiding portion 721 and a limiting portion 722. The guiding portion 721 is inclined to the plane where the limiting portion 722 is located, and the included angle between the guiding portion 721 and the limiting portion 722 is an obtuse angle. A notch 8 for accommodating the indentation wheel 3 is formed in the limiting portion 722. The cardboard enters under the indentation wheel 3 through the guiding portion 721 for indentation processing. The slightly upturned structure of the guiding portion 721 is more convenient for the cardboard to enter, and the limiting portion 722 is more conducive to the cardboard being smoothly introduced into the longitudinal cutting process after cross-cutting, without situations such as paper jams. The notch 8 has a sufficient length so that the swing of the indentation wheel 3 is not hindered.

[0037] In practical applications, in the equipment for producing packaging boxes, multiple indentation devices can be arranged in cooperation with the cross-cutting mechanism or the longitudinal cutting mechanism. The indentation devices can be fixedly arranged or installed on the guide rails to move relative to each other to adapt to different sizes of packaging boxes. Specifically, as Figure 1 and Figure 2 shown, a third screw hole 104 can be formed in the fixed seat 1 to facilitate the installation of the indentation device on the packaging box production equipment, or other fixed connection methods can be adopted.

[0038] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
