Description

Technical Field

[0001] This utility model relates to the field of cardboard cutting technology, specifically to a cardboard cutting device for carton production. Background Technology

[0002] Cardboard boxes are the most widely used packaging products. Depending on the materials used, there are corrugated cardboard boxes and single-layer cardboard boxes, etc., and there are various specifications and models. Commonly used cardboard boxes have three layers and five layers, etc. Each layer is divided into inner paper and corrugated paper, etc., such as kraft paper or kraft paper. The color and feel of various papers are different, and the color and feel of paper produced by different manufacturers are also different.

[0003] The existing method involves continuously feeding cardboard to a cutting roller, causing the cutting roller to rotate and thus cutting the cardboard.

[0004] Although the above equipment can adjust the cardboard, when adjusting the cutting blades on the cutting roller, the operator needs to loosen the bolts on the cutting blades so that the cutting blades can be installed in other positions on the cutting roller. Then the operator also needs to install other cutting blades at equal intervals, which increases the operator's workload. Utility Model Content

[0005] In view of this, the present invention provides a cardboard cutting device for carton production. The present invention can quickly adjust the spacing of the cutting blades, thereby avoiding the need for personnel to disassemble and adjust the cutting blades.

[0006] To solve the above-mentioned technical problems, this utility model provides a cardboard cutting device for carton production, including a housing and a cutting roller and a conveying roller respectively disposed between the inner sides of the housing. The cutting roller and the conveying roller are mounted on the housing, with the conveying roller located at the bottom of the cutting roller. An equidistant adjustment mechanism is provided inside the cutting roller, including a groove disposed on the inner wall of the cutting roller. Multiple moving blocks and a driving block are disposed in the groove, with the driving block located on the side of the multiple moving blocks closest to the driving block. The driving block drives the moving blocks to move equidistantly within the groove through a transmission component. Adjustment grooves are provided on both sides of the cutting roller, and the driving block and the moving blocks are... Mounting blocks are provided on both sides of the block, extending through the adjustment groove. The mounting blocks are fixed to the drive block and the moving block by welding. A cutting assembly is provided on the mounting block, which includes cutting blades mounted on the mounting block. The cardboard is conveyed by the conveying roller, which cuts the cardboard being conveyed. Then, through the action of the transmission component in the equidistant adjustment mechanism, the drive block is driven, which indirectly causes the moving block to move. This allows the spacing of the cutting blades on the mounting block to be adjusted, thus avoiding the need for personnel to disassemble and adjust the cutting blades.

[0007] The transmission assembly includes a hinge seat located on one side inside the cutting roller, with a third connecting rod rotatably mounted inside the hinge seat. A first connecting rod is rotatably connected to the center of the lower surface of the drive block. Multiple moving blocks have rotating columns mounted on their bottoms via bearings, with second connecting rods passing through each rotating column. The ends of two connected second connecting rods are rotatably connected. The end of the second connecting rod on the outermost moving block is rotatably connected to the end of the first connecting rod on the drive block. The second connecting rod closest to the inner wall of the cutting roller is rotatably connected to the third connecting rod on the hinge seat. The drive block and the moving blocks are connected via a drive assembly. Thus, the use of the first and second connecting rods or the third connecting rod causes the first connecting rod to rotate, thereby creating an interlocking effect.

[0008] The drive assembly includes a lead screw disposed between the two sides inside the cutting roller. The lead screw passes through the through hole of the moving block and is threaded to the drive block. Two sliding pillars are disposed on both sides of the lead screw and pass through the moving block; this facilitates the lead screw to drive a single drive block.

[0009] A drive disc is provided on the side of the conveyor roller, and the drive disc is fixed to one end of the lead screw; thus providing convenience for personnel to drive the drive disc.

[0010] The cutting assembly also includes cutting blades disposed on the upper and lower surfaces of multiple mounting blocks. The cutting blades are fixed to the upper and lower surfaces of the mounting blocks by bolts on the fixing plates, and the upper and lower cutting blades are fixed together by bolts in the middle; thus facilitating the disassembly and replacement of the cutting blades.

[0011] The cutting blade is made of high-speed steel; this increases the hardness of the cutting blade, thereby improving its cutting efficiency on cardboard.

[0012] The bottom of the shell is equipped with supporting feet, which provide support for the shell.

[0013] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0014] 1. When adjusting the spacing of the blades on the cutting roller, the blades need to be disassembled and reassembled. Then, by rotating the drive plate, the drive plate drives the lead screw to rotate, which in turn moves the drive block. During the movement, the first connecting rod at the bottom of the drive block pulls and rotates the second connecting rod at the bottom of the moving block, thereby moving multiple moving blocks. These multiple moving blocks move the mounting block within the adjustment groove, causing the mounting block to move the cutting blades. This indirectly allows the cutting blades mounted on the mounting block 204 to quickly and evenly space, thus improving the worker's work efficiency, saving workload, and greatly increasing the cutting speed of the cardboard.

[0015] 2. The upper and lower cutting blades are fixed to the mounting block by bolts, making it easy to replace the cutting blades when they wear out. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0027] like Figure 1-4As shown: This embodiment provides a cardboard cutting device for carton production, including a housing 100 and a cutting roller 101 and a conveying roller 102 respectively disposed between the inner sides of the housing 100. The conveying roller 102 is located at the bottom of the cutting roller 101. The cutting roller 101 and the conveying roller 102 are driven by an external drive mechanism to rotate relative to each other, thereby cutting and conveying the cardboard. An equidistant adjustment mechanism 200 is provided inside the cutting roller 101. The equidistant adjustment mechanism 200 includes a groove 104 disposed on the inner wall of the cutting roller 101. A plurality of moving blocks 203 and a driving block 201 are disposed inside the groove 104. The driving block 201 and the moving blocks 203 can move within the groove 104. The driving block 201 drives the moving blocks 203 to move within the groove 104 through a transmission assembly 300. The paperboard moves at equal intervals. Driven by the transmission component 300 in the equal interval adjustment mechanism 200, the drive block 201 can drive the moving block 203 in coordination. The cutting roller 101 is provided with adjustment grooves 105 on both sides. The drive block 201 and the moving block 203 are provided with mounting blocks 204 on both sides. The mounting blocks 204 are fixed to the drive block 201 and the moving block 203 by welding. When the drive block 201 moves, the transmission component 300 operates, so that the drive block 201 can drive the moving block 203 to move. This allows the mounting blocks 204 to be adjusted at equal intervals. The mounting blocks 204 pass through the adjustment grooves 105. The mounting blocks 204 are provided with a cutting component 500. The cutting component 500 includes a cutting blade 501 provided on the mounting blocks 204. The cutting blade 501 can cut the paperboard.

[0028] The cardboard is conveyed by the conveyor roller 102, and then the cutting roller 101 and the conveyor roller 102 are driven to rotate relative to each other by an external drive mechanism, so that the cutting roller 101 cuts the cardboard. When the personnel adjust the spacing of the blades on the cutting roller 101, the blades on the cutting roller 101 need to be disassembled and then reassembled onto the cutting roller 101. Then, the transmission component 300 in the equidistant adjustment mechanism 200 is operated, so that the drive block 201 drives multiple moving blocks 203, thereby moving the mounting block 204 within the adjustment groove 105. This indirectly allows the cutting component 500 mounted on the mounting block 204 to quickly achieve equidistant movement, thereby improving the work efficiency of the personnel, saving the workload of the personnel, and greatly increasing the cutting speed of the cardboard.

[0029] Transmission component 300, etc. Figure 3 and Figure 4 As shown,

[0030] The transmission assembly 300 includes a hinge seat 305 disposed on one side of the cutting roller 101. The hinge seat 305 is fixed to the side end of the cutting roller 101 by bolts. A third connecting rod 304 is rotatably disposed within the hinge seat 305 and can rotate within the hinge seat 305. A first connecting rod 301 is rotatably connected to the center of the lower surface of the drive block 201. The first connecting rod 301 is mounted on the drive block 201 and can swing on the drive block 201. The bottom of each of the multiple moving blocks 203 is provided with a rotating column 303 via bearings. The rotating column 303 is mounted on the moving block 203 and can rotate on the moving block 203. A second connecting rod 302 is fixedly installed inside the rotating column 303. The end of the second connecting rod 302 is provided with a rotating groove. The ends of the two connected second connecting rods 302 are rotatably connected. The end of the second connecting rod 302 on the outermost moving block 203 is rotatably connected to the end of the first connecting rod 301 on the drive block 201. The first connecting rod 301 and the second connecting rod 302 act as a hinge. The second connecting rod 302 on the side closest to the inner wall of the cutting roller 101 is rotatably connected to the third connecting rod 304 on the hinge seat 305. The third connecting rod 304 and the second connecting rod 302 act as a hinge. The drive block 201 and the moving block 203 are connected through the drive assembly 400.

[0031] The use of the drive assembly 400 drives the drive block 201, indirectly causing the first link 301 at the bottom of the drive block 201 to pull and rotate the closest link 302, indirectly causing the rotating column 303 at the bottom of the second link 302 to rotate, thereby enabling multiple second links 302 to work together, causing multiple second links 302 to rotate, which in turn causes multiple moving blocks 203 to move, indirectly enabling the moving blocks 203 to move at equal distances.

[0032] The drive assembly 400 includes a lead screw 401 disposed between the two sides inside the cutting roller 101. The lead screw 401 passes through the through hole 202 of the moving block 203, thereby preventing the lead screw 401 from driving the moving block 203. The lead screw 401 is threaded to the drive block 201, thereby facilitating the lead screw 401 to drive the drive block 201. Two sliding pillars 402 are disposed on both sides of the lead screw 401. The two sliding pillars 402 are fixedly installed inside the cutting roller 101. The two ends of the sliding pillars 402 are fixed inside the cutting roller 101 by welding. The two sliding pillars 402 pass through the moving block 203 and the drive block 201, thereby providing stability for the moving block 203 and the drive block 201.

[0033] A drive disk 106 is provided on the side end of the conveyor roller 102. The drive disk 106 is fixedly disposed to one end of the lead screw 401, so that the drive disk 106 can drive the lead screw 401, thereby enabling the lead screw 401 to drive the drive block 201.

[0034] The rotation of the drive disk 106 causes the lead screw 401 to rotate. During the rotation of the lead screw 401, the drive block 201 is driven. The first connecting rod 301 at the bottom of the drive block 201 rotates and drives the second connecting rod 302, thereby causing the rotating column 303 at the bottom of the moving block 203 to rotate. The multiple second connecting rods 302 work together to quickly move the moving block 203 equidistantly.

[0035] Cutting blade 501 Figure 1 Enlarged view of point A in the image is as follows Figure 2 As shown,

[0036] The cutting assembly 500 also includes cutting blades 501 disposed on the upper and lower surfaces of multiple mounting blocks 204. The cutting blades 501 are fixed to the upper and lower surfaces of the mounting blocks 204 by bolts on the fixing plate 502. The upper and lower cutting blades 501 are fixed together by bolts on the two sides of the middle part, which facilitates the disassembly and replacement of the cutting blades 501.

[0037] The cutting blade 501 is made of high-speed steel, which has high hardness, can maintain the sharpness of the blade, and improve cutting efficiency.
