Description

Technical Field

[0001] This utility model relates to the field of cardboard processing technology, and in particular to a device for cutting edges and corners in white cardboard processing. Background Technology

[0002] White cardboard is a sturdy, thick paper with a relatively high basis weight. Previously, based on basis weight, the most common cardboard was uncolored and commonly called white cardboard. In the production process of white cardboard, it needs to be cut, and a cutting device is used to trim the edges and corners.

[0003] Patent document CN220614119U discloses a cardboard cutting device, including: a device body and a fixing mechanism disposed inside the device body, the fixing mechanism including a sliding component and a positioning component; the present invention sets a limiting block inside the device body, in order to ensure accurate cutting of the cardboard body and prevent the cardboard body from shifting position during cutting when the cutting device performs cutting operation on the cardboard body, thereby improving the control operation of the cutting device on the cutting position accuracy of the cardboard body when cutting the cardboard body.

[0004] The cardboard cutting device proposed in the above patent documents only uses limiting blocks on both sides to restrict the cardboard during actual use. This is not only inconvenient for batch cutting of cardboard, but also results in uneven stress on the cardboard during cutting due to the lack of a limiting mechanism at the top, causing the other end of the cardboard to curl upwards and affecting the cutting quality. Therefore, we have designed a white cardboard processing and corner trimming device. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0031] Reference Figure 1 and Figure 2 A white cardboard processing and trimming device includes a processing table 1, on the surface of the processing table 1, a feeding mechanism 2, a limiting mechanism 3 and a cutting mechanism 4 are arranged sequentially from right to left.

[0032] Reference Figure 3 and Figure 4 In a preferred embodiment, the limiting mechanism 3 includes two limiting frames 301. Several limiting guide rollers 302 are rotatably arranged on the surface of the limiting frames 301. Two mounting brackets are fixedly arranged on the upper surface of the processing table 1. A bidirectional lead screw 303 is rotatably connected between the two mounting brackets. Two adjusting plates 304 are threadedly connected to the surface of the bidirectional lead screw 303. The bottom end of the adjusting plate 304 is fixedly connected to the top of the limiting frame 301. An adjusting motor 310 is arranged on the surface of the mounting bracket. The output shaft of the adjusting motor 310 is fixedly connected to one end of the bidirectional lead screw 303. The adjusting motor 310 can drive the bidirectional lead screw 303 to rotate, and the distance between the two limiting frames 301 can be adjusted. This is suitable for limiting paper of different widths.

[0033] It should be noted that a guide rod 309 is fixedly installed between the two mounting brackets, and a guide through hole matching the guide rod 309 is opened on the surface of the adjusting plate 304. The adjusting plate 304 is slidably connected to the surface of the guide rod 309 through the guide through hole, and the adjusting plate 304 can be moved and limited by the guide rod 309.

[0034] Reference Figure 5It should be further explained that two limiting fixing plates 305 are fixedly installed on the surface of the limiting frame 301. An electric telescopic rod 306 is fixedly installed on the upper surface of the limiting fixing plate 305. A limiting pressure plate 307 is fixedly installed at the telescopic end of the two electric telescopic rods 306. A limiting strip 308 is fixedly connected between the two limiting pressure plates 307. A rubber anti-slip pad is fixedly installed on the lower surface of the limiting strip 308.

[0035] It should be noted that using rubber anti-slip pads can increase the friction between the limiting pressure plate 307 and the cardboard, thereby improving the limiting effect.

[0036] It is worth noting that by setting a limiting mechanism 3 on the surface of the processing table 1, two limiting frames 301 can drive several limiting guide rollers 302 to limit and align the two sides of the white cardboard. The electric telescopic rod 306 can drive the limiting pressure plate 307 and the limiting strip 308 to press and fix the top of the white cardboard. This facilitates the limiting of the stacked white cardboard, prevents the white cardboard from moving up and down during the cutting process, improves the stability of the cutting process, and facilitates the batch cutting of the corners of the white cardboard.

[0037] It should be noted that the feeding mechanism 2 includes a feeding motor 201 and a feeding screw 202. The surface of the processing table 1 is provided with a strip groove 14. The feeding screw 202 is rotatably disposed inside the strip groove 14, and the surface of the feeding screw 202 is threadedly connected to a movable seat 203. A feeding push plate 204 is fixedly disposed on the upper surface of the movable seat 203.

[0038] The feeding motor 201 is fixedly installed on the side of the processing table 1, and the output shaft of the feeding motor 201 extends into the inside of the strip groove 14 and is fixedly connected to one end of the feeding screw 202. The feeding motor 201 can drive the feeding screw 202 to rotate, thereby driving the feeding push plate 204 to push the paper to move and feed.

[0039] Reference Figure 6 In a preferred embodiment, the cutting mechanism 4 includes a fixed frame 401. Two electric push rods 402 are fixedly mounted on the upper surface of the fixed frame 401. The telescopic ends of the two electric push rods 402 extend to the lower part of the fixed frame 401 and are fixedly connected to a movable frame 403. A cutter 404 is fixedly provided at the bottom of the movable frame 403. The position of the cutter 404 corresponds to one end of the limiting frame 301, and it can cut the corners of the cardboard between the limiting frames 301.

[0040] It should be noted that a waste collection trough 10 is provided on the surface of the processing table 1. The position of the waste collection trough 10 corresponds to that of the cutting mechanism 4. A feeding ramp 11 is provided on the top of the inner wall of the waste collection trough 10. Two pairs of baffles 12 are fixedly provided on the inner wall of the waste collection trough 10. A waste trough baffle 13 is inserted and installed between the two pairs of baffles 12.

[0041] Workers can remove the waste trough baffle 13 from between the baffles 12 to facilitate the cleaning of waste.

[0042] It should be noted that a jet box 6 is fixedly installed at the left end of the limiting frame 301. Several jet holes 9 are opened on the surface of the jet box 6. The jet box 6 has a triangular structure. The air outlet of the jet hole 9 corresponds to the position of the cutter 404. Several jet holes 9 are evenly distributed longitudinally on the surface of the jet box 6, which can uniformly spray air onto the surface of the processing table 1, improve the spray range, and spray air onto both ends of the long strip of cardboard scraps. The airflow blows the scraps into the waste collection tank 10.

[0043] It should be further explained that an air pump 7 is fixedly installed on the upper surface of the mounting bracket 401. A three-way pipe 5 is fixedly installed at the output end of the air pump 7. Air guide hoses 8 are fixedly installed at both output ends of the three-way pipe 5. The end of the air guide hose 8 away from the three-way pipe 5 is fixedly connected to the top of the jet box 6, and the output end of the air guide hose 8 extends into the interior of the jet box 6. The air pump 7 diverts air to the two air guide hoses 8 through the three-way pipe 5, and then uses the two air guide hoses 8 to input air into the two jet boxes 6.

[0044] It is worth noting that by providing an air jet box 6 at one end of the limiting frame 301, and with the air jet holes 9 of the two air jet boxes 6 facing downwards from the cutting mechanism 4, air jets can be sprayed onto the cutting position using the air jet holes 9 on the surface of the air jet box 6 during the cutting process. The airflow blows the cut scraps into the waste collection trough 10, thereby facilitating subsequent cutting operations and preventing waste from accumulating below the cutter 404 and affecting subsequent operations, thus achieving the purpose of automatic cleaning and collection of scraps.

[0045] Working principle: In use, several sheets of white cardboard are first stacked on the surface of the processing table 1, with the cardboard positioned between the two limiting frames 301. Then, the adjusting motor 310 drives the bidirectional lead screw 303 to rotate, which in turn moves the two adjusting plates 304 and the limiting frames 301. The limiting guide rollers 302 on the surface of the two limiting frames 301 are used to tidy and limit the two sides of the white cardboard. Then, the feeding motor 201 drives the feeding lead screw 202 to rotate, which in turn moves the moving seat 203 and the feeding push plate 204 to push the cardboard on the surface of the processing table 1, so that the front end of the cardboard moves to the lower part of the cutting mechanism 4. Then, the electric telescopic rod 306 on the surface of the limiting frame 301 drives the limiting pressure plate 307 and the limiting strip 308 to press and fix the top of the cardboard, so that the cardboard cannot move. Then, the electric push rod 402 drives the movable frame 403 and the cutter 404 to move downward. The cutter 404 cuts the edges and corners of the cardboard. After the cutting is completed, the air pump 7 delivers high-speed air into the two air jet boxes 6. Then, the air jet holes 9 on the surface of the air jet box 6 spray out high-speed air. The air blows the scraps left on the surface of the processing table 1 after cutting into the waste collection tank 10, so as to achieve the purpose of automatic cleaning and waste collection.

[0046] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
