Description

Technical Field

[0001] This utility model relates to the field of slotting machine technology, specifically to a carton slotting machine with adjustable blade spacing. Background Technology

[0002] Cardboard boxes are the most widely used packaging products. Depending on the materials used, there are corrugated cardboard boxes, single-layer cardboard boxes, etc., and various specifications and models. Three-layer and five-layer cardboard boxes are commonly used, while seven-layer boxes are less common. Each layer consists of linerboard, corrugated paper, and core paper. The color and feel of each type of paper are different, and the paper produced by different manufacturers also varies in color and feel. Cardboard box slotting refers to cutting the fold lines of the top and bottom flaps of the cardboard box onto a single piece of cardboard. This process is carried out after printing, simultaneously with creased stitching.

[0003] For example, Chinese utility model patent with publication number "CN219789430U" discloses an adjustable slotting machine for carton processing. It uses threaded grooves and sliding grooves on the surface of the cutting roller, along with a limiting plate, a fixing ring, and a slider inside the cutting blade, to allow the cutting blade to slide on the surface of the cutting roller and adjust the spacing between the cutting blades. This allows for slotting operations on various types of cartons. The structure is simple, convenient, and practical. Furthermore, through the cooperation between the cylinder and the lifting platform, it can also perform slotting operations on cartons of different thicknesses, improving the efficiency of carton slotting processing.

[0004] However, the aforementioned patents make it difficult to collect and process the waste material produced during slotting, which can easily cause the waste material to accumulate at the cutting edge, affecting the use of the device and causing inconvenience. Therefore, we propose a cardboard slotting machine with adjustable blade distance. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-5 This utility model provides a technical solution: a carton slotting machine with adjustable blade spacing, comprising: a placement plate 1;

[0027] A pusher unit installed on the surface of placement plate 1;

[0028] Debris collection box 102 installed at one end of placement plate 1;

[0029] A crushing unit installed inside the debris collection box 102;

[0030] Slotted unit installed on top of debris collection box 102

[0031] The top of the debris collection box 102 is provided with a debris collection port 103, the bottom of the debris collection box 102 is provided with a discharge port 104, and the bottom of the placement plate 1 is provided with a support leg 101.

[0032] Please see Figures 2-5 The crushing unit includes a third motor 4 mounted on the surface of the debris collection box 102, a third rotating shaft 401 mounted on the output end of the third motor 4, a first crushing roller 402 mounted on the surface of the third rotating shaft 401, and a second driving gear 403 mounted on one end of the third rotating shaft 401. The crushing unit also includes a fourth rotating shaft 404 mounted inside the debris collection box 102, a second crushing roller 405 mounted on the surface of the fourth rotating shaft 404, and a second driven gear 406 mounted on one end of the fourth rotating shaft 404. The second driven gear 406 is meshed with the second driving gear 403. One end of both the third rotating shaft 401 and the fourth rotating shaft 404 extends to the outside of the debris collection box 102 and is connected to the second driving gear 403 and the second driven gear 406, respectively.

[0033] Through the above technical solution, the waste material under the groove enters the debris collection box 102 through the debris collection port 103. The third motor 4 drives the third rotating shaft 401 to rotate, which in turn drives the first crushing roller 402 to rotate, thereby driving the second driving gear 403 to rotate. The second driving gear 403 drives the second driven gear 406 to move relative to each other, causing the fourth rotating shaft 404 to rotate. This causes the second crushing roller 405 to move relative to the first crushing roller 402, crushing the waste material generated by the groove. After crushing, the waste material is discharged from the debris collection box 102 through the discharge port 104.

[0034] Please see Figures 1-4 The feeding unit includes two cylinders 2 symmetrically installed, a connecting frame 202 installed at one end of the cylinder 2, a first slide groove 201 symmetrically opened on the surface of the cylinder 2, a slide plate 203 installed at one end of the connecting frame 202, and push plates 204 connected to both ends of the slide plate 203 through the first slide groove 201.

[0035] Using the above technical solution, the cardboard box that needs to be slotted is placed on top of the placement plate 1. The connecting frame 202 is moved by the cylinder 2, the slide plate 203 slides inside the first slide groove 201, and the push plate 204 is moved to push the cardboard box to the cutting blade 307.

[0036] Please see Figures 1-5The grooving unit includes a first motor 3, which is mounted on the surface of the debris collection box 102; a first rotating shaft 301 mounted on the output end of the first motor 3; a mounting cylinder 302 welded to the surface of the first rotating shaft 301; a second sliding groove 303 opened on the surface of the mounting cylinder 302; fixing grooves 304 arranged at equal intervals on the surface of the mounting cylinder 302; a connecting plate 305 sleeved on the surface of the mounting cylinder 302; a cutting blade 307 welded to the surface of the connecting plate 305; and bolts and nuts 306 mounted on the surface of the connecting plate 305. One end of the first rotating shaft 301 passes through the debris collection box 102 and is connected to a first driving gear 308. The grooving unit also includes a second rotating shaft 309, which is installed inside the debris collection box 102; a rotating roller 310 mounted on the surface of the second rotating shaft 309; one end of the second rotating shaft 309 passes through the debris collection box 102 and is connected to a first driven gear 311. The first driven gear 311 and the first driving gear 308 are meshed.

[0037] Through the above technical solution, the bolt and nut 306 are removed from the surface of the connecting plate 305, and the cutting blade 307 is moved to a suitable position through the second sliding groove 303. Then, the bolt and nut 306 are installed inside the fixing groove 304, thereby fixing the cutting blade 307 to the surface of the mounting cylinder 302. This allows for easy adjustment of the position of the cutting blade 307 as needed, and facilitates changing the position of the cutting blade 307 according to the size of the carton or the required grooving position of the carton, improving the practicality of the device. The first motor 3 drives the first rotating shaft 301 to rotate, causing the mounting cylinder 302 to rotate, which in turn causes the cutting blade 307 to rotate. In conjunction with the first driving gear 308 and the first driven gear 311, the second rotating shaft 309 rotates, which in turn causes the rotating roller 310 to rotate, allowing the carton to move. During the movement, the cutting blade 307 grooves the carton, and the rotating roller 310 moves it away.

[0038] All electrical devices in this invention are powered by an external power source;

[0039] Working principle and usage process: Place the cardboard box that needs to be slotted on top of the placement plate 1. The connecting frame 202 is moved by the cylinder 2, causing the slide plate 203 to slide inside the first slide groove 201, which in turn moves the push plate 204, pushing the cardboard box to the cutting blade 307. The first motor 3 drives the first rotating shaft 301 to rotate, causing the mounting cylinder 302 to rotate, which in turn rotates the cutting blade 307. In conjunction with the first driving gear 308 and the first driven gear 311, the second rotating shaft 309 rotates, which in turn rotates the rotating roller 310, allowing the cardboard box to move. During this movement, the cutting blade 307 slots the cardboard box. The material is slotted and then moved away by the rotating roller 310. The waste material under the slots enters the waste collection box 102 through the waste collection port 103. The third motor 4 drives the third rotating shaft 401 to rotate, which in turn drives the first crushing roller 402 to rotate, thereby driving the second driving gear 403 to rotate. The second driving gear 403 drives the second driven gear 406 to move relative to each other, causing the fourth rotating shaft 404 to rotate. This causes the second crushing roller 405 to move relative to the first crushing roller 402, crushing the waste material generated by the slotting. After crushing, the waste material is discharged from the waste collection box 102 through the discharge port 104.
