Description

Technical Field

[0001] The utility model relates to the field of packaging machinery and equipment, in particular to a grinding wheel grooving device for packaging paper boxes. Background Art

[0002] In the carton manufacturing process, slotting refers to cutting a certain depth of incision on the cardboard to facilitate subsequent folding and forming. The traditional slotting method usually uses a blade or a knife for cutting. This method is prone to burrs or uneven edges during the cutting process, affecting the appearance quality and durability of the product. With the development of the packaging industry, the demand for packaging cartons is increasing, and high-quality carton production is inseparable from precise slotting technology. The traditional manual slotting method is inefficient and difficult to ensure consistency. Therefore, automated or semi-automated grinding wheel slotting devices are widely used in modern industrial production to improve production efficiency and product quality.

[0003] The patent with patent announcement number CN219789431U discloses a corrugated paper grooving separation tool, including a knife handle and a knife seat. One end of the knife handle is integrally connected to the knife seat. Two oblique slots distributed in an "eight" shape are respectively provided on both sides of the knife seat. Blades are respectively clamped in the two oblique slots. The upper sides of the opposite ends of the two blades are respectively provided with cutting edges. The height positions of the two oblique slots are staggered to form a height difference between the two blades; the upper side of the knife seat is fixedly connected to a pressure block by a clamping bolt, and the bottom two sides of the pressure block respectively press the tops of the two blades. Two clamping bolts are provided and symmetrically arranged on both sides of the knife seat by loosening the clamping bolts. The pressure block can be removed by loosening the clamping bolts, thereby facilitating the replacement of the blades.

[0004] The above patent design is a corrugated paper grooving separation tool. The height positions of the blades on both sides are staggered. The height difference is set according to the actual requirements of different paper thicknesses. The two blades cut the hollow corrugated cardboard in sequence to form a V-shaped paper groove. However, when the tool is installed on the grooving machine for cutting, the installation position of the tool needs to be carefully debugged to ensure the accuracy of the grooving. This process is often time-consuming and complicated, which increases the time cost of production preparation, and the tool often needs to be replaced to meet different cutting requirements. Therefore, it is necessary to design a packaging paper box grinding wheel grooving device in response to the shortcomings of the existing technology. Utility Model Content

[0005] In order to overcome the shortcomings of existing cardboard slotting tools that require debugging to ensure accurate cutting and are troublesome to maintain, a flexibly adjustable packaging paper box grinding wheel slotting device is provided.

[0006] Technical solution: A packaging paper box grinding wheel grooving device, comprising a mounting handle, a connecting block, a bearing I, a grinding wheel, a pulley I, a movable block, a fixing screw and a driving member, the mounting handle being the mounting body of the grooving device, the mounting handle being a rectangular long block, the end of the mounting handle being fixedly connected to the connecting block, the bearing I being provided inside the connecting block, the connecting block being rotatably mounted with the grinding wheel through the bearing I, the rotating shaft of the grinding wheel being fixedly connected with the pulley I, the connecting block being provided with a threaded sleeve, the mounting handle being docked with the movable block through the connecting block, the mounting handle and the movable block being separable from each other for docking installation, the movable block being provided with a bearing adapted to the rotating shaft of the grinding wheel on the side close to the connecting block, the movable block being tightened on the connecting block by the fixing screw, the connecting block and the movable block being formed into a U-shaped clamp after being tightened by the fixing screw and limiting and clamping the grinding wheel inside, the pulley I being driven by an external driving member so that the pulley I synchronously drives the grinding wheel to perform grooving.

[0008] Furthermore, the driving component includes a mounting plate, a motor, a pulley II and a driving belt. A mounting plate is fixedly connected to one side of the mounting handle, a motor is mounted on the mounting plate, a pulley II is mounted on the output shaft of the mounting plate, and a driving belt is wound between the pulley I and the pulley II.

[0009] Furthermore, the connecting end surfaces of the connecting block and the movable block are both concave and convex, so that the connecting block and the movable block are embedded in each other and firmly spliced, avoiding the grinding wheel clamped between the connecting block and the movable block from moving after the connecting block and the movable block are spliced, thereby affecting the accuracy of the grinding wheel grooving. The splicing top surface of the connecting block and the movable block is a slope, which facilitates avoiding position toward the drive belt.

[0012] The beneficial effects are: 1. The utility model can ensure the stable positioning of the grinding wheel during the slotting process through the concave and convex butt end faces of the connecting block and the movable block, and the fixing screws therebetween, thereby preventing the grinding wheel from moving during work and ensuring the accuracy of the slotting.

DETAILED DESCRIPTION

[0020] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Example 1: A packaging paper box grinding wheel slotting device, such as Figure 1-Figure 3 As shown, it includes a mounting handle 1, a connecting block 101, a bearing Ⅰ2, a grinding wheel 3, a pulley Ⅰ4, a movable block 5, a fixing screw 6 and a driving member. The mounting handle 1 is the mounting body of the slotting device. The mounting handle 1 is a rectangular long block. The end of the mounting handle 1 is fixedly connected to the connecting block 101. The connecting block 101 is provided with a bearing Ⅰ2. The connecting block 101 is rotatably mounted with a grinding wheel 3 through the bearing Ⅰ2. The rotating shaft of the grinding wheel 3 is fixedly connected with a pulley Ⅰ4. The connecting block 101 is provided with a threaded sleeve. The mounting handle 1 is connected to the connecting block 101 is docked with a movable block 5, and the mounting handle 1 and the movable block 5 can be separated from each other for docking installation. The movable block 5 is provided with a bearing adapted to the rotating shaft of the grinding wheel 3 on the side close to the connecting block 101. The movable block 5 is tightened on the connecting block 101 by the fixing screw 6. After the connecting block 101 and the movable block 5 are tightened by the fixing screw 6, they form a U-shaped clamp and limit and clamp the grinding wheel 3 inside. The pulley Ⅰ4 is driven by an external driving member, so that the pulley Ⅰ4 synchronously drives the grinding wheel 3 to perform grooving.

[0022] like Figure 3 As shown, the grinding surface of the grinding wheel 3 is pointed, and the specific grooving angle of the grinding wheel 3 is 95-98°. The grinding wheel 3 forms a V-shaped groove when grinding the cardboard.

[0023] like Figure 1-Figure 3 As shown, the connecting end surfaces of the connecting block 101 and the movable block 5 are both concave and convex, so that the connecting block 101 and the movable block 5 are embedded in each other and firmly spliced, to avoid the grinding wheel 3 clamped between the connecting block 101 and the movable block 5 from moving after the connecting block 101 and the movable block 5 are spliced, thereby affecting the accuracy of the grooving of the grinding wheel 3. The splicing top surface of the connecting block 101 and the movable block 5 is a slope, which facilitates avoiding the drive belt 15.

[0024] When assembling the device, first put one end of the rotating shaft of the grinding wheel 3 into the bearing Ⅰ2 on the connecting block 101, and then align the other end of the rotating shaft of the grinding wheel 3 with the bearing on the movable block 5, and screw the fixing screw 6 into the movable block 5 so that the fixing screw 6 passes through the movable block 5 and is screwed into the threaded sleeve on the connecting block 101. As the fixing screw 6 gradually tightens the connecting block 101 and the movable block 5, the concave and convex surfaces on the connecting block 101 and the movable block 5 will be embedded in each other, thereby improving the stability of the connecting block 101 and the movable block 5 when they are tightened by the fixing screw 6, avoiding the connection The grinding wheel 3 clamped between the connecting block 101 and the movable block 5 is offset. When the fixing screw 6 firmly tightens the grinding wheel 3 between the connecting block 101 and the movable block 5, the grinding wheel 3 can be firmly assembled on the mounting handle 1. After the mounting handle 1 is installed on the slot machine, the top surface of the connecting block 101 and the movable block 5 will form an inclined surface after being combined, which is convenient for the subsequent belt wrapped on the pulley Ⅰ4 to avoid position, and the subsequent grinding operation of the packaging paper can be carried out. During grinding, the tip of the grinding wheel 3 will grind a V-shaped groove on the cardboard, so that the cardboard can be folded into a packaging box through the V-shaped groove.

[0025] Example 2: Based on Example 1, Figure 1 and Figure 2 As shown, the driving component includes a mounting plate 12, a motor 13, a pulley II 14 and a driving belt 15. The mounting plate 12 is fixedly connected to one side of the mounting handle 1, the motor 13 is mounted on the mounting plate 12, the pulley II 14 is mounted on the output shaft of the mounting plate 12, and the driving belt 15 is wound between the pulley I4 and the pulley II 14.

[0026] like Figure 2 and Figure 4 As shown, the adjusting member includes a fixed plate 7, a screw 8, a bearing II 9, a rotating shaft 10 and a guide rod 11. The fixing plate 7 is rotatably connected to the mounting end of the mounting handle 1, and the top of the fixing plate 7 is threadedly connected to the screw 8. The end of the mounting handle 1 is symmetrically provided with bearings II 9, and the rotating shaft 10 is rotatably connected between the bearings II 9. The screw 8 is threaded through the rotating shaft 10, and two guide rods 11 are symmetrically fixed in the end of the mounting handle 1, and the bearings II 9 are both slidably connected between the guide rods 11.

[0027] like Figure 1 and Figure 4 As shown, an indicator rod 16 is fixed to one side of the fixed plate 7, and a scale plate 17 is provided on the side of the mounting handle 1 corresponding to the fixed plate 7. The indicator rod 16 and the scale plate 17 are adapted to each other, so that when the screw rod 8 adjusts the angle of the mounting handle 1 and the fixed plate 7, the adjusted angle will be passed through the scale plate 17, and the indicator rod 16 will indicate on the scale plate 17, so that the angle of the mounting handle 1 can be known by rotation adjustment.

[0028] The output shaft of the motor 13 drives the pulley II 14 to rotate, and the rotating pulley II 14 drives the pulley I 4 to rotate through the belt drive belt 15. The rotating pulley I 4 will synchronously drive the grinding wheel 3 to rotate at a high speed, so that the grinding wheel 3 can cut and groove the cardboard in contact. When the cutting angle or depth of the grinding wheel 3 needs to be adjusted, the screw rod 8 is twisted so that the thread on the screw rod 8 acts on the rotating shaft 10, so that the rotating shaft 10 can slide on the screw rod 8. When the rotating shaft 10 rotates, the bearings II 9 at both ends of the rotating shaft 10 will rotate on the guide The mounting handle 1 is adapted to slide on the rod 11, and the sliding rotating shaft 10 will drive the mounting handle 1 to rotate with the connection point with the fixed plate 7 as the rotation point, thereby adjusting the angle of the mounting handle 1, thereby changing the different slotting angles of the grinding wheel 3 on the mounting handle 1, and when the mounting handle 1 and the fixed plate 7 rotate relative to each other, the indicator rod 16 on the fixed plate 7 will indicate different scales on the scale plate 17, and the user can know the changed slotting angle of the grinding wheel 3 by observing the indicator rod 16 and the scale plate 17, thereby facilitating the user to accurately adjust the slotting angle of the grinding wheel 3.
