Abstract
Description
Technical Field
[0001] This application relates to the field of printers, and more particularly to a cutting device and a heat press printer. Background Technology
[0002] In heat transfer printing applications, the printed paper typically needs to be cut to meet the size requirements for subsequent use or processing. Current technology often employs mechanical cutting devices for this purpose. A slider slides along a guide rod, and a cutter is fixedly mounted on the slider. The slider moves along the guide rod, causing the cutter to move and thus cut the paper. In practice, the operator first slides the cutter to the edge of the paper, then pushes the slider to move the cutter along a predetermined path, thus cutting the paper.
[0003] However, the moment the cutter contacts the edge of the printing paper and begins cutting, the cutting force applied by the cutter can easily cause the edge area to lift and deform. This deformation directly affects the contact state between the cutter and the printing paper, causing the cutting path to deviate from the predetermined trajectory. Ultimately, this results in uneven, rough, or even tilted surfaces on the cut paper, severely impacting cutting accuracy and product quality, and failing to meet the needs of practical applications with high requirements for cutting results.

[0025] This application provides a cutting device having a first direction X and a second direction Y intersecting and arranged, and the device includes a guide frame 100, a slider 200, a cutter 300, two mounting plates 400, and rollers 500. Specifically, the guide frame 100 is arranged along the first direction X, the slider 200 is slidably arranged on the guide frame 100, the cutter 300 is fixedly arranged on the slider 200, the cutting end of the cutter 300 protrudes from the bottom surface of the slider 200, the mounting plates 400 are arranged on the slider 200, and the two mounting plates 400 are respectively arranged on both sides of the slider 200 along the second direction Y, and at least one roller 500 is rotatably arranged on each mounting plate 400.
[0026] Please see Figure 1 , Figure 2 as well as Figure 3 As shown, the first direction X is the horizontal direction and the second direction Y is the vertical direction. The first direction X and the second direction Y are intersected. When the printing paper needs to be cut, the slider 200 can first move along the first direction X about the guide frame 100. During the movement, the rollers 500 on both sides of the slider 200 will first contact the printing paper and press it down. The cutter 300 is located between the left and right rollers 500. Then the cutter 300 contacts the printing paper. At this time, since the printing paper is pressed down by the rollers 500, the contact between the cutter 300 and the printing paper will not cause the printing paper to warp. As the slider 200 continues to drive the cutter 300 to move, the printing paper is cut.
[0027] Understandably, each time the slider 200 moves the cutter 300 to cut the printing paper, the roller 500 presses down on the printing paper to prevent the edges from warping during cutting and affecting the cutting effect.
[0028] Furthermore, in order to ensure that the rollers 500 press down on the printing paper during each cut, two rollers 500 are rotatably mounted on each mounting plate 400, and the two rollers 500 are spaced apart, thus providing stable support for the movement of the slider 200. The cutting end of the cutter 300 is V-shaped. It should be noted that the cutting end of the cutter 300 is located in the area formed by the four rollers 500, so that the rollers 500 can press down on the printing paper before each cut by the cutter 300 to prevent the sides from warping and affecting the cutting effect.
[0029] In some embodiments, the guide frame 100 includes two spaced-apart uprights 110, with a guide rod 120 disposed between the two uprights 110.
[0030] Please continue reading. Figure 1 and Figure 2 As shown, the upright plate 110 is located at both ends of the guide rod 120, and both ends of the guide rod 120 are fixedly connected to the upright plate 110. The two upright plates 110 and the guide rod 120 form a gantry shape. The guide rod 120 is mainly used to guide the slider 200 and guide the slider 200 to move along the first direction X.
[0031] In other embodiments, the guide rod 120 can also be replaced by a guide rail, which can also be slidably connected to the slider 200.
[0032] In some embodiments, the slider 200 has first mounting holes 201 on both sides along the second direction Y. A limit rod 202 is provided in the first mounting hole 201 and extends to the outside of the slider 200. An elongated hole 401 is provided on the mounting plate 400 and communicates with the corresponding first mounting hole 201. The limit rod 202 passes through the elongated hole 401.
[0033] like Figure 2 and Figure 3 As shown, the printing paper is subjected to downward pressure by the gravity of the mounting plate 400 and the roller 500. In order to allow the mounting plate 400 and the roller 500 to have space for vertical floating, the mounting plate 400 can be slidably disposed on the side of the slider 200. Specifically, the limiting rod 202 is fixedly installed in the first mounting hole 201, and the limiting rod 202 passes through the elongated hole 401 of each mounting plate 400. Since the length of the elongated hole 401 in the height direction is greater than the diameter of the limiting rod 202, the mounting plate 400 can move up and down a certain distance under the guidance of the limiting rod 202 to a certain extent, thereby realizing sliding along the height direction.
[0034] In this embodiment, the slider 200 has two first mounting holes 201 on each side along the second direction Y, and each side should also have two limiting rods 202 screwed into the first mounting holes 201. Correspondingly, the mounting plate 400 at each position of the first mounting hole 201 should also have two elongated holes 401.
[0035] For example, to facilitate the installation of the limiting rod 202, the first mounting hole 201 can be a threaded hole, and the limiting rod 202 can be a bolt. The bolt is divided into a threaded section and a smooth section. The threaded section is screwed into the threaded hole, and the smooth section is located in the elongated hole 401, thereby reducing the friction between the limiting rod 202 and the inner wall of the elongated hole 401. It should be noted that the bolt should also have a head to prevent the mounting plate 400 from detaching, that is, the diameter of the head should be greater than the width of the elongated hole 401.
[0036] In some embodiments, the cutting device further includes a third direction Z intersecting the first direction X and the second direction Y respectively. The slider 200 includes an integrally formed moving part 210 and a driven part 220. The moving part 210 is slidably disposed on the guide frame 100. The cutter 300 is fixedly disposed on the driven part 220. The end of the cutter 300 protrudes from the bottom surface of the driven part 220. A second mounting hole 203 is provided on the moving part 210 at each position of the mounting plate 400. A spring plunger 600 is disposed in the second mounting hole 203. The end of the spring plunger 600 abuts against the mounting plate 400 along the third direction Z.
[0037] See Figure 2 , Figure 3 , Figure 4 as well as Figure 5 As shown, the slider 200 is composed of an integrally formed moving part 210 and a driven part 220. The length of the moving part 210 in the second direction Y should be greater than the length of the driven part 220, so that the slider 200 is "T" shaped. The purpose of this design is to avoid the spring plunger 600, so that the spring plunger 600 can abut against the mounting plate 400 when it is set on the moving part 210.
[0038] Specifically, since the pressure exerted by the mounting plate 400 and the roller 500 on the printing paper may result in insufficient downward pressure, causing the printing paper to lift and warp during cutting, two second mounting holes 203 can be made through the upper surface of the moving part 210 to increase the downward pressure. A spring plunger 600 is installed in each second mounting hole 203, and the end of the spring plunger 600 abuts against the mounting plate 400, thereby providing a downward pressure to the mounting plate 400. The downward pressure from the spring plunger 600, combined with the gravity of the mounting plate 400 and the roller 500, prevents the printing paper from lifting and warping during cutting.
[0039] It should be noted that the second mounting hole 203 is a threaded hole. The spring plunger 600 is screwed into the slider 200. Furthermore, the downward pressure acting on the mounting plate 400 can be adjusted by adjusting the length of the spring plunger 600 extending into the second mounting hole 203, so as to prevent the roller 500 from leaving indentations on the printing paper due to excessive downward pressure.
[0040] In some embodiments, the movable part 210 has a limiting groove 211 on both sides along the second direction Y, the first mounting hole 201 is formed on the inner side of the limiting groove 211 along the second direction Y, and the mounting plate 400 is at least partially disposed in the limiting groove 211.
[0041] Please see Figure 4 and Figure 5 As shown, when the mounting plate 400 floats up and down under the guidance of the limiting rod 202, it may tilt. In order to make the mounting plate 400 float up and down more smoothly, limiting grooves 211 adapted to the mounting plate 400 are opened on both sides of the slider 200 along the second direction Y. The mounting plate 400 is at least partially located in the limiting grooves 211, so that the mounting plate 400 can be guided to float up and down through the limiting grooves 211.
[0042] In some embodiments, the slider 200 is provided with a third mounting hole 204 extending through it along a first direction X, and a guide member 700 is provided in the third mounting hole 204, the guide member 700 being slidably disposed on the guide rod 120.
[0043] Please see Figure 1 , Figure 2 as well as Figure 4 As shown, in order to allow the movable part 210 of the slider 200 to be slidably disposed on the guide rod 120, a third mounting hole 204 is opened through the movable part 210 along the first direction X, and a guide member 700 is installed in the third mounting hole 204. The guide member 700 is slidably connected to the guide rod 120.
[0044] For example, guide 700 is a linear bearing.
[0045] In some embodiments, the mounting plate 400 includes an integrally formed connecting portion 410 and mounting portion 420. An elongated hole 401 is formed through the connecting portion 410 along the second direction Y. An abutting portion 430 is provided on the side of the mounting portion 420 facing the slider 200 at the connection between the connecting portion 410 and the connecting portion 410. The end of the spring plunger 600 abuts against the abutting portion 430.
[0046] like Figure 2 , Figure 3 as well as Figure 6As shown, in order to enable the mounting plate 400 to better bear the downward pressure from the spring plunger 600 and be guided by the limiting groove 211, the mounting plate 400 is divided into three parts: a connecting part 410, a mounting part 420, and an abutting part 430. The connecting part 410, the mounting part 420, and the abutting part 430 are integrally formed and connected. The thickness of the connecting part 410 is thinner than that of the mounting part 420, so that all or most of the connecting part 410 can be placed in the limiting groove 211 and be guided more stably.
[0047] In order to withstand the downward pressure from the spring plunger 600, an abutment part 430 is provided at the connection between the connecting part 410 and the mounting part 420. The abutment part 430 is located on the side facing the slider 200. At this time, the abutment part 430 is located directly below the second mounting hole 203, so that the spring plunger 600 abuts against the abutment part 430, and then the downward pressure is transmitted to the printing paper through the roller 500.
[0048] This embodiment also provides a heat transfer printer, which includes a cutting device, a frame 800, and a fixing plate 900 as described above. The frame 800 has an outlet, and the fixing plate 900 is fixedly disposed on the frame 800 and located at the outlet position. The cutting device is disposed on the fixing plate 900, and the fixing plate 900 has an avoidance groove 910 along the first direction X, which is located at the position of the cutter 300.
[0049] See Figure 7 and Figure 8 As shown, the vertical plate 110 of the cutting device is fixedly installed on the side of the fixed plate 900 and located at the exit position of the printer, so that the printed paper can be fed through the cutting device. After the cutting position is determined, the cutting worker can push the slider 200 to drive the cutter 300 to move along the guide rod 120 to cut the paper.
[0050] Furthermore, in order to prevent the cutter 300 from scratching the surface of the fixing plate 900, a clearance groove 910 is provided directly below the cutter 300 to avoid the cutter 300. In some embodiments, an extension plate 1000 is provided at the end of the fixed plate 900 away from the outlet, and the extension plate 1000 is flush with the fixed plate 900.
[0051] Please continue reading. Figure 7 and Figure 8 As shown, in order to accommodate longer printing paper, an extension plate 1000 can be bolted to the end of the fixed plate 900, thereby extending the length of the fixed plate 900. In order to prevent damage to the printing paper at the connection between the extension plate 1000 and the fixed plate 900, the upper surface of the extension plate 1000 is flush with the upper surface of the fixed plate 900.
