Description

Technical Field

[0001] This utility model relates to the field of wire marking tube printing technology, specifically to a wire marking machine printing module structure. Background Technology

[0002] The wire marking machine's printing module uses thermal transfer technology. By heating the print head, the ink on the ribbon melts, thus transferring the ink onto the surface of the wire to form numbers. This technology allows the wire marking machine to print characters on PVC tubing, heat shrink tubing, special self-adhesive labels, and marking tapes. It is suitable for secondary wire marking in electrical control, power distribution, and switchgear, meeting the needs of power plants, electrical equipment manufacturers, substations, and the power industry for wire identification marking.

[0003] CN209869740U discloses a tube pressing and feeding structure for a wire marking machine. It includes a front rubber roller and a rear rubber roller on the front and rear sides of the print head, and a front pressing roller and a rear pressing roller disposed on the front and rear rubber rollers for pressing the wire marking tube. The front pressing roller and the rear pressing roller are respectively connected to the same driving device through corresponding support arms. Under the drive of the driving device, the front pressing roller and the rear pressing roller move synchronously in opposite directions in the vertical direction, so that the front end of the wire marking tube rolls forward in sequence under the cooperation of the front and rear pressing rollers and the corresponding rubber rollers. After the front end of the wire marking tube passes the rear pressing roller, the front pressing roller and the rear pressing roller are disconnected from the driving device and press against the wire marking tube under the action of the corresponding pressure mechanism.

[0004] When the above-mentioned wire marking machine is in use, the printing module is equipped with an independent drive device, which only controls the forward drive of the printing roller. Other modules are designed separately, resulting in a complex structure and weak linkage. The operation of threading and clamping the tube is also quite cumbersome. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a wire marking machine printing module structure to solve the technical problems of complex structure and weak linkage of existing wire marking tube machines, and the cumbersome operation of tube threading and clamping.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0007] This utility model provides a wire marking machine printing module structure, including: a printing roller, a pressing section, a driving section, and a conveying section. The pressing section is disposed on one side of the printing roller and is used to press the wire marking tube against the printing roller. The driving section has at least two rotary driving ends, one of which is connected to the printing roller and is used to drive the printing roller to rotate. The conveying section includes a conveying roller, a floating roller, and a linkage. The conveying roller is connected to the other rotary driving end of the driving section. The floating roller is connected to the flip cover of the wire marking machine through the linkage, so that when the flip cover is closed or opened, the floating roller is moved by the linkage to a first state close to the conveying roller to press the wire marking tube, and a second state away from the conveying roller to release the wire marking tube, respectively.

[0008] In some embodiments, the conveying roller and the floating roller are mounted via a first central shaft and a second central shaft, respectively, with a first gear and a second gear respectively sleeved at the same height position on the first central shaft and the second central shaft; wherein, when the floating roller is in a first state, the first gear and the second gear are meshed; when the floating roller is in a second state, the first gear and the second gear are spaced apart.

[0009] In some embodiments, the linkage includes a pressure roller support sheet metal, a lid pressure roller pressure spring, and a box strap pressure roller return spring. The pressure roller support sheet metal is rotatably mounted on the core support plate of the marking machine, with one end connected to the floating roller. The other end of the pressure roller support sheet metal has a first connecting portion and a second connecting portion protruding outward on both sides. The first connecting portion is connected to the flip cover through the lid pressure roller pressure spring, and the second connecting portion is connected to the core support plate through the box strap pressure roller return spring.

[0010] When the flip-top is closed, a force is generated on the pressure roller spring of the lid, which drives the pressure roller support sheet metal to rotate around the rotating end, causing the floating roller to be in the first state. At this time, the box belt pressure roller reset spring is in the stretched state.

[0011] When the flip cover is opened, the release and reset of the pressure roller reset spring of the box belt causes the pressure roller support sheet metal to rotate and reset around the rotating end. At this time, the floating roller is in the second state.

[0012] In some embodiments, the pressure roller support sheet metal is provided with an arc-shaped limiting groove, and a limiting post is provided on the core support plate at a position corresponding to the limiting groove. One end of the limiting post passes through the limiting groove and is slidably connected to the limiting groove so that when the pressure roller support sheet metal rotates along its rotating end, the limiting post slides in the limiting groove.

[0013] In some embodiments, the drive unit includes a first motor and a plurality of transmission gears, which are sequentially meshed together. The drive end of the first motor, the printing roller, and the conveying roller are respectively connected to one of the plurality of transmission gears.

[0014] In some embodiments, the pressure tube section includes a printhead substrate, a printhead swing arm, and a driving member. The printhead substrate is disposed on one side of the print roller and connected to the printhead swing arm. The printhead swing arm has a connecting end and a swinging end. Its connecting end is rotatably connected to the core support plate of the wire marking machine, and its swinging end is connected to the driving end of the driving member, so that the swinging end rotates around the connecting end under the driving action of the driving member, thereby driving the printhead substrate to move towards or away from the print roller.

[0015] In some embodiments, the driving component includes a head-lifting cam, a second motor, a printhead pressure spring, and a mounting bracket. The head-lifting cam is disposed on one side of the swing end and is rotatably connected to the mechanism support plate. The driving end of the second motor is connected to the head-lifting cam to drive its rotation. One end of the printhead pressure spring is connected to the swing end of the printhead lever, and the other end is connected to the mechanism support plate via the mounting bracket. Two printhead pressure springs are provided, with one end of each spring connected to one side of the printhead lever and the upper surface of the swing end of the lever, respectively, and the other ends of both springs connected to the mounting bracket. A mounting base is provided at the swing end of the printhead lever corresponding to the head-lifting cam. A connecting shaft is rotatably mounted on the mounting base. The connecting shaft contacts the head-lifting cam when the head-lifting cam rotates, thereby driving the swing end of the printhead lever to rotate around the connecting end.

[0016] In some embodiments, the pressing section further includes a cutting cam, which is connected to the wheel shaft of the head lifting cam. One side of the cutting cam corresponds to the cutting frame of the marking machine and is used to intermittently drive the cutter to move under the rotation of the cutting cam to cut the marking tube.

[0017] Compared with existing technologies, the wire marking machine printing module structure provided by this utility model, through the setting of a printing roller, a tube pressing section, a drive section, and a conveying section, uses the tube pressing section to apply pressure to press the wire marking tube against the printing roller. The floating roller of the conveying section is connected to the flip cover of the wire marking machine through a linkage component, realizing the linkage between the floating roller and the flip cover in the open and closed states. When the flip cover is closed, the linkage component can drive the floating roller to move to the first state close to the conveying roller, so that the floating roller touches the wire marking tube, and the wire marking tube is clamped by the conveying roller and the floating roller. The drive section can drive the printing roller to rotate for printing, and at the same time drive the conveying roller to rotate, moving the wire marking tube forward, realizing the functions of printing, clamping, and conveying the wire marking tube. When the flip cover is open, the linkage component can drive the floating roller to move to the second state away from the conveying roller to release the wire marking tube. This solution integrates functions such as clamping, conveying, and printing into one unit. The structure is simple and reliable. When releasing the tube, the floating roller can be moved away from the conveying roller by opening the flip cover. The tube clamping is automatically performed when the flip cover is closed. This structure is reasonable and compact, and easy to operate. Attached Figure Description

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0033] To address the technical problems of complex structure and weak linkage in wire marking machines, as well as the cumbersome operations of threading and clamping tubes, this utility model provides a wire marking machine printing module structure that integrates functions such as clamping, conveying, and printing. The structure is simple and reliable. When releasing tubes, the floating roller can be moved away from the conveying roller by opening the flip cover, facilitating the threading and clamping operations.

[0034] Please see Figures 1 to 8 The wire marking machine printing module structure includes: a printing roller 1, a pressing tube section 2, a driving section 3, and a conveying section 4. The pressing tube section 2 is located on one side of the printing roller 1 and is used to press the wire marking tube against the printing roller 1. The driving section 3 has at least two rotary driving ends, one of which is connected to the printing roller 1 and is used to drive the printing roller 1 to rotate. The conveying section 4 includes a conveying roller 41, a floating roller 42, and a linkage 43. The conveying roller 41 is connected to the other rotary driving end of the driving section 3. The floating roller 42 is connected to the flip cover of the wire marking machine through the linkage 43, so that when the flip cover is closed or opened, the floating roller 42 is moved by the linkage 43 to a first state close to the conveying roller 41 to press the wire marking tube, and a second state away from the conveying roller 41 to release the wire marking tube.

[0035] In this device, the pressure tube section 2 is located on one side of the printing roller 1. The pressure tube section 2 can apply pressure to press the wire marking tube against the printing roller 1, so that the wire marking tube contacts the printing roller 1 for printing. The floating roller 42 of the conveying section 4 is connected to the flip cover of the wire marking machine through the linkage 43. When the flip cover is closed, the linkage 43 can drive the floating roller 42 to move to the first state close to the conveying roller 41, so that the floating roller 42 touches the wire marking tube and the wire marking tube is clamped by the conveying roller 41 and the floating roller 42. The two driving ends of the driving section 3 are connected to the printing roller 1 and the conveying roller 41 respectively. It can drive the printing roller 1 to rotate for printing and can also drive the conveying roller 41 to rotate, thereby driving the wire marking tube to move forward. This realizes the functions of printing, clamping and conveying the wire marking tube. When the flip cover is opened, the linkage 43 can drive the floating roller 42 to move to the second state away from the conveying roller 41 to release the wire marking tube.

[0036] Furthermore, the wire marking machine printing module structure also includes a core support plate 5, which is used to install the printing roller 1, the pressure tube section 2, the drive section 3, and the conveying section 4, etc.

[0037] To achieve synchronous driving of the printing roller 1 and the conveyor unit 4, preferably, in this embodiment, please refer to... Figure 1 and Figure 2 The drive unit 3 includes a first motor and several transmission gears. The several transmission gears are arranged in sequence and meshed to form multiple rotary drive ends. Each transmission gear is rotatably mounted on the core support plate 5. The drive end of the first motor, the printing roller 1 and the conveying roller 41 are respectively connected to one of the several transmission gears and fixed on the gear shaft of the corresponding transmission gear.

[0038] In practice, the first motor drives one of the transmission gears to rotate. Under the meshing connection of the transmission gear set, the rotational motion is transmitted to each transmission gear, thereby driving the printing roller 1 and the conveyor roller 41 to rotate. Specifically, the rotational speed of the printing roller 1 and the conveyor roller 41 can be adjusted by designing the transmission ratio of the transmission gears.

[0039] It should be noted that in other possible embodiments, the drive unit 3 may also be in other forms, such as using a structure of multiple interconnected conveyor belts, with the drive end of the first motor, the printing roller 1 and the conveyor roller 41 respectively fixedly connected to the axle of one of the pulleys.

[0040] During line marking printing, the pressure applied by the pressing part 2 to the line marking tube causes the line marking tube to contact the printing roller 1. Preferably, in this embodiment, please refer to... Figures 1 to 5 The pressure tube section 2 includes a printhead substrate 21, a printhead swing arm 22, and a drive component 23.

[0041] Specifically, the printhead base plate 21 is fixed to the middle of the printhead swing arm 22 by bolts, so that the printhead base plate 21 is disposed on one side of the print roller 1. The two ends of the printhead swing arm 22 form a connecting end and a swing end, respectively. The connection position of the connecting end and the swing end is designed by bending. The printhead base plate 21 is located at this bend. The connecting end is rotatably connected to the core support plate 5 through the swing arm pivot 221. In fact, the swing arm pivot 221 is fixed on the core support plate 5. The connecting end of the printhead swing arm 22 is rotatably mounted on the swing arm pivot 221, so that the swing end can rotate around the swing arm pivot 221. The swing end is connected to the driving end of the driving member 23, so that the swing end rotates around the connecting end under the driving action of the driving member 23, driving the printhead base plate 21 to move towards or away from the print roller 1.

[0042] When the printhead substrate 21 moves toward the print roller 1, it is in a pressing state. At this time, the printhead substrate 21 is in close contact with the ribbon, the ribbon is in close contact with the wire tube, and the wire tube is in close contact with the printing roller, thus realizing the pressing printing function. At the same time, the pressure applied by the pressing part 2 presses the wire tube against the print roller 1, so that the wire tube can fully contact the print roller 1, thereby improving the printing clarity. When the printhead substrate 21 moves away from the print roller 1, it is in a relaxed state. At this time, the distance between the printhead substrate 21 and the print roller 1 increases, which facilitates the tube output and release.

[0043] In one embodiment, please refer to Figures 3 to 5 The driving component 23 includes a head-lifting cam 231, a second motor, a printhead pressure spring 232, and a fixing frame 233. The head-lifting cam 231 is located on one side of the swing end and is rotatably connected to the core support plate 5. The driving end of the second motor is connected to the head-lifting cam 231 to drive the head-lifting cam 231 to rotate. One end of the printhead pressure spring 232 is connected to the swing end of the printhead swing arm 22, and the other end is connected to the core support plate 5 through the fixing frame 233. Specifically, there are two printhead pressure springs 232. One printhead pressure spring 232 has one end connected to a lug on one side of the printhead swing arm 22 and the other end connected to the fixing frame 233. The other printhead pressure spring 232 has one end connected to a lug on the upper surface of the swing end of the printhead swing arm 22 and the other end connected to the fixing frame 233.

[0044] In practice, the second motor drives the head to lift the cam 231 to rotate, which can intermittently drive the swing end of the print head swing arm 22 to swing away from the print roller 1. The print head pressure spring 232 can elastically reset, causing the swing end of the print head swing arm 22 to swing towards the print roller 1 until it resets.

[0045] Furthermore, in some embodiments, please refer to Figures 1 to 5 A mounting base 234 is provided at the swing end of the printhead swing arm 22, corresponding to the position of the printhead lifting cam 231. A connecting shaft 235 is rotatably mounted on the mounting base 234. When the printhead lifting cam 231 rotates, the connecting shaft 235 contacts the printhead lifting cam 231, thereby driving the swing end of the printhead swing arm 22 to rotate around the connecting end, which can reduce contact friction.

[0046] Furthermore, the pressure tube section 2 also includes a limiting structure, which includes a limiting slide rod 236 and a limiting slide groove 237. The limiting slide rod 236 is fixed to the swing end of the print head swing rod 22, and the limiting slide groove 237 is opened on the mechanism support plate 5, allowing one end of the limiting slide rod 236 to extend into and slide in the limiting slide groove 237 to limit the swing of the print head swing rod 22.

[0047] In one embodiment, the pressing section 2 further includes a cutter cam 24, which is sleeved on the axle of the head lifting cam 231 and fixedly connected to the axle. One side of the cutter cam 24 corresponds to the cutter holder of the marking machine. In practice, the cutter cam 24 rotates with the head lifting cam 231 and can intermittently drive the cutter to move to cut the marking tube under the action of rotation. When the pressing section 2 is in the pressing state, the cutter moves away from the movement position of the marking tube. When the marking tube is printed, the drive member 23 drives the head lifting cam 231 to rotate, so that the pressing section 2 is in a relaxed state. At this time, the drive member 23 also drives the cutter cam 24 to rotate synchronously, so that the cutter moves toward the marking tube and cuts the marking tube.

[0048] Preferably, in this embodiment, please refer to Figure 1 , Figure 2 , Figures 6 to 8 The conveying roller 41 and the floating roller 42 are respectively mounted via a first central shaft and a second central shaft. The first central shaft is rotatably mounted on the mechanism support plate 5, and the second central shaft is rotatably mounted on the linkage 43. A first gear 411 and a second gear 421 are respectively sleeved at the same height position of the first central shaft and the second central shaft. When the floating roller 42 is in the first state, the first gear 411 and the second gear 421 are meshed and connected, so that in the first state, the conveying roller 41 can drive the floating roller 42 to rotate synchronously and convey the wire tube forward, which has higher conveying stability. When the floating roller 42 is in the second state, the first gear 411 and the second gear 421 are spaced apart.

[0049] In one embodiment, please refer to Figures 6 to 8The linkage component 43 includes a pressure roller support sheet metal 431, a lid pressure roller pressure spring 432, and a box strap pressure roller return spring 433. The pressure roller support sheet metal 431 is rotatably mounted on the mechanism support plate 5 via a support shaft 4315. One end of the pressure roller support sheet metal 431 is connected to the floating roller 42. The other end of the pressure roller support sheet metal 431 has a first connecting part 4311 and a second connecting part 4312 protruding outward on both sides. Both the first connecting part 4311 and the second connecting part 4312 are provided with hanging holes for connecting springs. The first connecting part 4311 is connected to the flip cover via the lid pressure roller pressure spring 432, and the second connecting part 4312 is connected to the plate frame provided on the mechanism support plate 5 via the box strap pressure roller return spring 433.

[0050] When the flip cover is closed, a force is generated on the pressure roller spring 432 of the cover, which drives the pressure roller support sheet metal 431 to rotate around the rotating end, causing the floating roller 42 to be in the first state and touch the wire tube. At this time, the box tape pressure roller reset spring 433 is in the stretched state.

[0051] When the flip cover is opened, the release and reset of the pressure roller reset spring 433 causes the pressure roller support sheet metal 431 to rotate and reset around the rotating end. At this time, the floating roller 42 is in the second state and the wire tube is released.

[0052] Furthermore, in some embodiments, please refer to Figures 6 to 8 The conveying unit 4 also includes a limiting component, which includes a limiting groove 4313 and a limiting post 4314. The limiting groove 4313 is formed on the pressure roller support sheet metal 431 and is arc-shaped. The limiting post 4314 is fixedly provided on the core support plate 5 at a position corresponding to the limiting groove 4313. One end of the limiting post 4314 passes through the limiting groove 4313 and is slidably connected to the limiting groove 4313 so that when the pressure roller support sheet metal 431 rotates along its rotating end, the limiting post 4314 slides in the limiting groove 4313 to limit the rotation of the pressure roller support sheet metal 431.

[0053] Working principle: During implementation, the second motor drives the printhead swing arm 22 to the relaxed state, opens the cover of the wire marking machine, and resets the floating roller 42 to the second state by the reset spring 433 of the cartridge pressure roller, moving it away from the conveyor roller 41. After placing the wire tube into the printing module structure, the cover is closed. The cartridge pressure roller pressure spring 432 and the pressure roller support sheet metal 431 drive the floating roller 42 to the first state, so that the conveyor roller 41 and the floating roller 42 clamp the wire tube. The second motor drives the head to lift the cam 231 and rotate, driving the printhead swing arm 22 to rotate to the tube pressing state, so that the printhead substrate 21 presses the wire tube tightly against one side of the print roller 1. The first motor drives the print roller 1, the conveyor roller 41 and the floating roller 42 to rotate synchronously through multiple transmission gears, and performs printing and handling operations synchronously.

[0054] This invention comprises a printing roller 1, a pressing section 2, a driving section 3, and a conveying section 4. The pressing section 2 applies pressure to press the wire marking tube against the printing roller 1 for printing. The floating roller 42 of the conveying section 4 is connected to the flip cover of the wire marking machine via a linkage 43, enabling linkage between the floating roller 42 and the flip cover in both open and closed states. When the flip cover is closed, the linkage 43 drives the floating roller 42 to move to a first state close to the conveying roller 41, so that the floating roller 42 presses against the wire marking tube, and the wire marking tube is clamped by the conveying roller 41 and the floating roller 42. The two driving ends of the driving section 3 are connected to the printing roller 1 and the conveying roller 41 respectively. It can drive the printing roller 1 to rotate for printing and also drive the conveying roller 41 to rotate, moving the wire marking tube forward, thus realizing the functions of printing, clamping, and conveying the wire marking tube. When the flip cover is open, the linkage 43 drives the floating roller 42 to move to a second state away from the conveying roller 41 to release the wire marking tube. This solution integrates functions such as tube clamping, conveying, and printing into one unit. It has a simple and reliable structure. When placing the tube, the floating roller 42 can be moved away from the conveying roller 41 by opening the flip cover. The tube clamping can be performed automatically when the flip cover is closed. The structure is reasonable and compact, and the operation is convenient.
