Description

Technical Field

[0001] This invention relates to the field of cutting technology, and more particularly to an automatic cutting device. Background Technology

[0002] Currently, advertising production refers to the commercial activity of creating advertising works that can be published, set up, posted, and distributed according to advertising design requirements. Advertising means to inform widely. Advertising is a means of publicity that uses a certain form of media to publicly and widely convey information to the public for a specific purpose.

[0003] Among them, the cutting device for advertising production is one of the essential pieces of equipment in the advertising production process. It can cut advertising posters of different sizes into fixed lengths, making it convenient for operators to use.

[0004] The common cutting method on the market is still for operators to use hand-held scissors to cut advertising posters, which has low cutting efficiency and accuracy. To address this, we propose an automatic cutting device to solve the above problems. The cutting device can cut posters efficiently. Summary of the Invention

[0005] The purpose of this invention is to solve the problems existing in the prior art by proposing an automatic cutting device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An automatic cutting device includes: a cutting box, on both sides of the inside of the cutting box, gears are rotatably mounted, two sets of gears are meshed together, a drive arm is mounted on each set of gears, and a drive mechanism is mounted on each set of drive arms. The driving mechanism includes a first slide groove formed in the middle of both sets of driving arms, a first slider slidably installed in both sets of first slide grooves, a first connecting shaft rotatably installed in the middle of both sets of first sliders, a second slide groove formed at one end of both sets of driving arms, a second slider slidably installed in both sets of second slide grooves, a second connecting shaft rotatably installed in the middle of both sets of second sliders, and a push block fixedly installed at one end of both sets of second connecting shafts.

[0007] Preferably, the two sets of first connecting shafts are fixedly installed on one end of the sidewall of the two sets of gears, and the two sets of first connecting shafts are respectively distributed at the top of the upper gear and the bottom of the lower gear.

[0008] Preferably, limit slides are fixedly installed on both sides of one end of the cutting box, and the two sets of limit slides are slidably connected to the two sets of push blocks respectively, so as to limit the two sets of push blocks.

[0009] Preferably, a cutting blade is fixedly installed at one end of the push block on one side, and a docking cover is fixedly installed at one end of the push block on the other side. The docking cover and the cutting blade correspond to each other, and after docking, the docking cover and the cutting blade can cut the advertising poster.

[0010] Preferably, a positioning shaft is fixedly installed at the other end of each of the two sets of drive arms. The positioning shaft is rotatably connected to one side of the cutting box. A placement groove is opened in the middle of one end of the cutting box. The placement groove corresponds to the docking cover and the cutting blade, which can position the two sets of drive arms.

[0011] Preferably, a motor is fixedly installed on one side of the cutting box, the motor drive output end is connected to the transmission shaft, and the other end of the transmission shaft is fixedly installed to the gear shaft located on one side, which can drive the gear to rotate.

[0012] Compared with the prior art, the beneficial effects of the present invention are: This invention uses a drive motor to rotate a gear located on one side. Since the two sets of gears are meshed, when one set of gears rotates, the other set of gears will rotate synchronously in opposite directions. This causes the first connecting shaft on the two sets of gears to drive the first slider to slide in the first slide groove. This allows the two sets of drive arms to rotate synchronously inward or outward along the positioning shaft. As the two sets of drive arms move, the second sliders located in the two sets of second slide grooves will synchronously push the two sets of push blocks inward or outward, causing the cutting blades and docking covers on the two sets of push blocks to dock, thus efficiently cutting the advertising poster.

[0013] With limit slides fixedly installed on both sides of one end of the cutting box, and the two sets of limit slides slidably connected to the two sets of push blocks respectively, when the two sets of drive arms push the two sets of push blocks to move, the two sets of push blocks can be limited in conjunction with the limit sliders on both sides of the cutting box to ensure that the two sets of push blocks move up and down in the vertical direction, so that the cutting blades and docking covers on the two sets of push blocks can be accurately docked, and the advertising poster can be cut.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0017] Reference Figure 1-3 An automatic cutting device includes: a cutting box 1, with gears 11 rotatably mounted on both sides inside the cutting box 1, two sets of gears 11 meshing together, a drive arm 12 mounted on each of the two sets of gears 11, and a drive mechanism mounted on each of the two sets of drive arms 12. The drive mechanism includes a first slide groove 2 opened in the middle of both sets of drive arms 12, a first slider 21 slidably installed in both sets of first slide grooves 2, a first connecting shaft 22 rotatably installed in the middle of both sets of first sliders 21, a second slide groove 23 opened at one end of both sets of drive arms 12, a second slider 24 slidably installed in both sets of second slide grooves 23, a second connecting shaft 25 rotatably installed in the middle of both sets of second sliders 24, and a push block 26 fixedly installed at one end of both sets of second connecting shafts 25. The two sets of first connecting shafts 22 are respectively fixedly installed at one end of the side wall of the two sets of gears 11. The two sets of first connecting shafts 22 are respectively distributed at the top of the upper gear 11 and the bottom of the lower gear 11. A motor 33 is fixedly installed on one side of the cutting box 1. The drive output end of the motor 33 is connected to... The drive shaft is connected to the drive shaft, and the other end of the drive shaft is fixedly installed on the central shaft of the gear 11 on one side. It can drive the gear 11 to rotate. The drive motor 33 drives the gear 11 on one side to rotate. Since the two sets of gears 11 are meshed, when one set of gears 11 rotates, the other set of gears 11 will rotate synchronously in opposite directions. This causes the first connecting shaft 22 on the two sets of gears 11 to drive the first slider 21 to slide in the first slide groove 2. This can push the two sets of drive arms 12 to rotate synchronously inward or outward along the positioning shaft 14. As the two sets of drive arms 12 move, the second slider 24 located in the two sets of second slide grooves 23 will synchronously push the two sets of push blocks 26 inward or outward, so that the cutting blades 31 and the docking cover 32 on the two sets of push blocks 26 can dock, thus efficiently cutting the advertising poster.

[0018] Furthermore, limiting slides 3 are fixedly installed on both sides of one end of the cutting box 1. The two sets of limiting slides 3 are slidably connected to the two sets of push blocks 26 respectively, which can limit the two sets of push blocks 26. When the two sets of drive arms 12 push the two sets of push blocks 26 to move, they cooperate with the limiting sliders on both sides of the cutting box 1 to limit the two sets of push blocks 26, ensuring that the two sets of push blocks move up and down in the vertical direction, so that the cutting blades 31 and the docking covers 32 on the two sets of push blocks 26 are accurately docked, and the advertising poster is cut.

[0019] Furthermore, a cutting blade 31 is fixedly installed at one end of the push block 26 on one side, and a docking cover 32 is fixedly installed at one end of the push block 26 on the other side. The docking cover 32 and the cutting blade 31 correspond to each other. After docking, the docking cover 32 and the cutting blade 31 can cut the advertising poster. When the two sets of drive arms 12 push the two sets of push blocks 26 to move, the cutting blade 31 and the docking cover 32 on the two sets of push blocks 26 can dock, and the advertising poster placed inside the placement slot 13 can be cut.

[0020] Furthermore, each of the two sets of drive arms 12 has a positioning shaft 14 fixedly installed at the other end. The positioning shaft 14 is rotatably connected to one side of the cutting box 1. A placement groove 13 is opened in the middle of one end of the cutting box 1. The placement groove 13 corresponds to the docking cover 32 and the cutting blade 31, which can position the two sets of drive arms 12. When the drive motor 33 drives the drive arms 12 on the two sets of gears 11 to rotate, the positioning shaft 14 can limit the two sets of drive arms 12, ensuring that the two sets of drive arms 12 rotate around the positioning shaft 14.

[0021] In use, the advertising poster is first placed in the placement slot 13 at the desired cutting position. The drive motor 33 drives the gear 11 on one side to rotate. Since the two sets of gears 11 are meshed, when one set of gears 11 rotates, the other set of gears 11 will rotate synchronously in opposite directions. This causes the first connecting shaft 22 on the two sets of gears 11 to drive the first slider 21 to slide in the first slide groove 2. This allows the two sets of drive arms 12 to rotate synchronously inward or outward along the positioning shaft 14. As the two sets of drive arms 12 move, the second sliders 24 located in the two sets of second slide grooves 23 will move in tandem. The two sets of push blocks 26 are pushed inward or outward, so that the cutting blades 31 and the docking covers 32 on the two sets of push blocks 26 are docked, which efficiently cuts the advertising poster. At the same time, the two sets of limit slides 3 are fixedly installed on both sides of one end of the cutting box 1, and the two sets of limit slides 3 are slidably connected to the two sets of push blocks 26 respectively. When the two sets of drive arms 12 push the two sets of push blocks 26 to move, the limit sliders on both sides of the cutting box 1 can limit the two sets of push blocks 26 to ensure that the two sets of push arms move vertically up and down, so that the cutting blades 31 and the docking covers 32 on the two sets of push blocks 26 are accurately docked, and the advertising poster is cut.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
