Detailed Implementation

[0036] 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.

[0037] Please see Figures 1-12 A printing, stamping, and scanning system includes a housing frame assembly, on which a printing module 1, a double-sided stamping module 2, a scanning module 3, a paper guide 5, and a paper output module 4 are sequentially arranged. The printing module 1 and the scanning module 3 are well-known technologies and will not be described in detail.

[0038] The device includes a housing 21, within which two stamping mechanisms are arranged: a front-mounted first stamping mechanism 22a and a rear-mounted second stamping mechanism 22b. The first and second stamping mechanisms 22a and 22b are installed vertically inverted. The first stamping mechanism 22a prints the front of the paper, and the second stamping mechanism 22b prints the back of the paper. Alternatively, the second stamping mechanism 22b can print the front of the paper, and the first stamping mechanism 22a can print the back of the paper. The front of the housing 21 has a feed inlet 2100 corresponding to the first stamping mechanism 22a, and the rear of the housing 21 has a discharge outlet 2101 corresponding to the second stamping mechanism 22b.

[0039] Continue reading Figure 5 , Figure 7 and Figure 8 In one embodiment of this utility model, the stamping mechanism includes a stamping assembly and a first roller 2203 rotatably mounted on the housing 21. The stamping assembly and the first roller 2203 are arranged vertically opposite each other. The stamping assembly includes a stamping shaft 2200 rotatably mounted on the housing 21, and a stamping wheel 2201 and a paper-pressing wheel 2202 disposed on the stamping shaft 2200. The stamping wheel 2201 and the stamping shaft 2200 slide along the axial direction and are in a circumferential upper limit engagement to prevent relative circumferential rotation between them. Specifically, the stamping shaft 2200 is a D-shaped hole shaft, and the shape and size of the shaft hole of the stamping wheel 2201 match it. The stamping wheel 2201 and the first roller 2203 together clamp the paper and transport the paper. The stamping wheel 2201 stamps the paper. There are two paper-pressing wheels 2202, which are respectively disposed at both ends of the stamping shaft 2200. The paper-pressing wheels 2202 and the first roller 2203 together clamp and transport the paper. The stamping shaft 2200 is driven to rotate by the first motor 2209 and the corresponding transmission components. The transmission components are preferably gear transmission structures, but conveyor belt mechanisms, sprocket mechanisms, etc. can also be used.

[0040] Continue reading Figure 5 , Figure 7 , Figure 8 , Figure 9 In one embodiment of this utility model, the stamping mechanism further includes a moving component that adjusts the axial position of the stamping wheel 2201 on the stamping shaft 2200. The moving component includes a lead screw 2205, a nut seat 2206, and a connecting frame 2207. The lead screw 2205 is rotatably mounted on the housing 21 and is driven by a second motor 2210 and a corresponding transmission component. The transmission component is preferably a gear transmission structure, but a conveyor belt mechanism, a sprocket mechanism, etc., can also be used. Nut seat 2206 is screwed onto lead screw 2205. Connecting frame 2207 is connected to nut seat 2206. The left and right sides of connecting frame 2207 each have a pushing part 22070. Stamping wheel 2201 is located between the left and right pushing parts 22070. Pushing part 22070 has a U-shaped opening that is fastened to stamping shaft 2200. The limiting effect of connecting frame 2207 and stamping shaft 2200 prevents circumferential rotation of both connecting frame 2207 and nut seat 2206. The two pushing parts 22070 are used to push stamping wheel 2201 along the axial direction of stamping shaft 2200, thereby adjusting the axial position of stamping wheel 2201 on stamping shaft 2200. Pushing part 22070 is not fixed to stamping wheel 2201 and will not affect the rotation of stamping wheel 2201.

[0041] When the moving component is working, the second motor 2210 drives the lead screw 2205 to rotate. The lead screw 2205 drives the nut seat 2206 and the connecting frame 2207 to move axially together. The connecting frame 2207 drives the stamping wheel 2201 to move axially, thereby adjusting the position of the stamping wheel 2201.

[0042] In other embodiments of this utility model, the moving component may also employ mechanisms such as cylinders, slides, and electric push rods.

[0043] Continue reading Figure 8 In one embodiment of this utility model, the stamping wheel 2201 is equipped with an ink-filling wheel 2208 that is tightly attached to its wheel surface. Specifically, the ink-filling wheel 2208 is disposed on the connecting frame 2207 and located between the stamping wheel 2201 and the corresponding nut seat 2206. The ink-filling wheel 2208 includes a wheel axle and an ink-filling sponge sleeved on the wheel axle.

[0044] Continue reading Figure 5 and Figure 7 In one embodiment of this utility model, the stamping mechanism further includes a second roller 2204 rotatably mounted on the housing 21. The second roller 2204 is arranged parallel to the first roller 2203 and conveys the paper by rotation. Figure 4 As shown, in the first stamping mechanism 22a, the first roller 2203 is located at the lower end of the stamping shaft 2200, and the second roller 2204 is located in front of the first roller 2203. Figure 6 As shown, in the second stamping mechanism 22b, the first roller 2203 is located at the upper end of the stamping shaft 2200, and the second roller 2204 is located in front of the first roller 2203. The gap between the first roller 2203 and the stamping wheel 2201 in the first stamping mechanism 22a and the gap between the first roller 2203 and the stamping wheel 2201 in the second stamping mechanism 22b are at the same height. Both the first roller 2203 and the second roller 2204 are rubber-coated rollers.

[0045] It should be noted that the first stamping mechanism 22a and the second stamping mechanism 22b in this utility model have basically the same structure, but their installation positions and directions are different.

[0046] Continue reading Figure 6In one embodiment of this utility model, the second stamping mechanism 22b is equipped with an ink cleaning mechanism 23. The ink cleaning mechanism 23 includes an ink cleaning component 2300, a pressing assembly, and a mounting frame 2301. The ink cleaning component 2300 is an ink-absorbing sponge, which is mounted on the mounting frame 2301 and fits against the two rollers in the second stamping mechanism 22b to clean the ink on the rollers. A connecting shaft 2302 is provided on the mounting frame 2301, and the two ends of the connecting shaft 2302 slide vertically and vertically with the U-shaped opening on the housing 21. The mounting frame 2301 and the ink cleaning component 2300 are supported on the rollers. The pressing assembly is used to press the mounting frame 2301, thereby adjusting the pressure between the ink cleaning component 2300 and the rollers in the second stamping mechanism 22b. The clamping assembly includes a drive shaft 2303 rotatably mounted on the housing 21, several cams 2304 disposed on the drive shaft 2303, and a third motor 2305. The third motor 2305 drives the drive shaft 2303 to rotate via a synchronous belt mechanism. The synchronous belt mechanism can also be replaced by a gear transmission structure, a sprocket transmission structure, etc. The cams 2304 press down on the mounting bracket 2301. The drive shaft 2303 can drive the cams 2304 to swing, thereby adjusting the downward pressure of the cams 2304 on the mounting bracket 2301, and thus adjusting the clamping degree between the ink cleaning component 2300 and the roller in the second stamping mechanism 22b.

[0047] Continue reading Figure 3 In one embodiment of this utility model, the housing 21 is further provided with a first guide component 24, a second guide component 25, a third guide component 26, a fourth guide component 27, a fifth guide component 28, and a sixth guide component 211. All six guide components are channel structures composed of upper and lower plates, serving to guide the paper. The first guide component 24 is located in front of the feed inlet 2100 of the housing 21 and is responsible for feeding the paper. The second guide component 25 is located between the feed inlet 2100 and the second roller 2204 of the first stamping mechanism 22a, and is responsible for guiding the paper between the second roller 2204 of the first stamping mechanism 22a and the moving component. The third guide component 26 is located between the second roller 2204 and the first roller 2203 of the first stamping mechanism 22a, and is responsible for guiding the paper between the first roller 2203 of the first stamping mechanism 22a and the stamping wheel 2201. The fourth guide assembly 27 is located between the first roller 2203 of the first stamping mechanism 22a and the second roller 2204 of the second stamping mechanism 22b, and is responsible for guiding the paper between the second roller 2204 of the second stamping mechanism 22b and the moving assembly. The fifth guide assembly 28 is located between the second roller 2204 and the first roller 2203 of the second stamping mechanism 22b, and is responsible for guiding the paper between the first roller 2203 of the second stamping mechanism 22b and the stamping wheel 2201. The sixth guide assembly 211 is located between the discharge port 2101 of the housing 21 and the first roller 2203 of the second stamping mechanism 22b, and is responsible for guiding the paper out of the machine.

[0048] Further reading Figure 3 In one embodiment of this utility model, a traction wheel assembly 29 is provided on the second guide assembly 25. Multiple openings are provided on both the upper and lower plates of the second guide assembly 25. The traction wheel assembly 29 includes an active traction wheel shaft 2900, an active traction wheel 2901, a passive traction wheel shaft 2902, and a passive traction wheel 2903. The active traction wheel shaft 2900 is rotatably mounted to the housing 21 and is located on the upper side of the second guide assembly 25. Several active traction wheels 2901 are provided on the active traction wheel shaft 2900. The active traction wheels 2901 are connected to the second guide assembly 25 via the active traction wheel shaft 2902. The opening of the second guide assembly 25 extends into the gap between the upper and lower plates of the second guide assembly 25. The passive traction wheel shaft 2902 is rotatably mounted to the housing 21 and is located on the lower side of the second guide assembly 25. There are several passive traction wheels 2903, all of which are set on the active traction wheel shaft 2900. The passive traction wheels 2903 extend into the gap between the upper and lower plates of the second guide assembly 25 through the opening of the second guide assembly 25. In this way, the active traction wheel 2901 and the passive traction wheel 2903 are set in a one-to-one correspondence, which can clamp the paper and feed it backward.

[0049] Further reading Figure 3 In one embodiment of this utility model, a fourth motor 210 installed inside the housing 21 is also included. The fourth motor 210 drives the active traction wheel shaft 2900, the first roller 2203 and the second roller 2204 of the first stamping mechanism 22a, and the first roller 2203 and the second roller 2204 of the second stamping mechanism 22b to rotate respectively through a transmission assembly. The transmission assembly is preferably a gear transmission assembly, but a synchronous belt mechanism, a sprocket mechanism, etc. can also be used. This is a well-known technology in the field of mechanical transmission and will not be described in detail.

[0050] The working process of the double-sided stamping module 2 of this utility model is as follows: the paper enters the feed inlet 2100 through the first guide component 24, then is printed on the front side first through the first stamping mechanism 22a, then on the back side through the second stamping mechanism 22b, and finally exits from the discharge outlet 2101. In this process, ink remains on the front side of the paper after being stamped by the first stamping mechanism 22a. When the front side of the paper passes through the second stamping mechanism 22b, it comes into contact with the first roller 2203 and the second roller 2204 of the second stamping mechanism 22b, potentially leaving ink on them. This utility model uses an ink cleaning component 2300 to clean the first roller 2203 and the second roller 2204 of the second stamping mechanism 22b to avoid affecting subsequent stamping.

[0051] Continue reading Figure 1 , Figure 10 and Figure 11In one embodiment of this utility model, the paper output module 4 is located at the rear end of the scanning module 3.

The rotation of the conveying wheels by the motor and pulley assembly is known technology and will not be described in detail.

[0052] Continue reading Figure 1 and Figure 12 In one embodiment of this utility model, the paper guide 5 is located between the scanning module 3 and the paper output module 4, and has a paper guide port 500 for paper to pass through. The front end of the paper guide port 500 faces the paper output port of the scanning module 3, and the rear end of the paper guide port 500 faces the paper input port of the paper output module 4.
