Description

Technical Field

[0001] This application relates to the technical field of cable marking, and in particular to a cable marking device. Background Technology

[0002] In factories, printing on cables can be done using either inkjet printing or printing wheels. Printing wheels come in two types: embossed and debossed. They utilize the thermoplastic material just extruded from the cable surface to print raised or recessed characters. Printing wheels are used for marking products such as wires, cables, and high-voltage ignition wires.

[0003] Because the cable is in a high-temperature state after being extruded from the extruder, the surface material of the cable sometimes adheres to the side wall of the printing wheel during the printing process. If the printing wheel with cable material adhering to it then prints on the cable, the printing will be unclear, which will affect the pass rate. Utility Model Content

[0004] To address the issue of cable quality being affected when printing on cables after the printing wheel has cable material adhering to it, this application provides a cable printing device, which includes a cleaning component for cleaning the sidewall of the printing wheel.

[0005] The cable marking device provided in this application adopts the following technical solution:

[0006] A cable printing device includes a printing mechanism, which comprises a cleaning component, a mounting plate, and a printing wheel. The printing wheel is mounted on the mounting plate. The cleaning component includes a brush plate and a position adjusting screw. The brush plate is mounted on the mounting plate and located on one side of the printing wheel. The position adjusting screw is mounted on the mounting plate. The brush plate is threadedly connected to the position adjusting screw. The brush plate is also provided with bristles for brushing away impurities on the printing wheel.

[0007] By adopting the above technical solution, if the surface material of the cable adheres to the side wall of the printing wheel, the brush plate can clean the side wall of the printing wheel. When replacing the printing wheel with one of different diameters, in order to ensure that the bristles on the brush plate can effectively brush away the impurities on the side wall of the printing wheel, the distance between the brush plate and the printing wheel can be adjusted by the position adjustment screw. Through the setting of the cleaning component, the impurities on the side wall of the printing wheel are effectively cleaned, reducing the occurrence of unclear or incomplete text printed on the cable, thereby effectively improving the cable qualification rate.

[0008] Preferably, the printing mechanism further includes sliders and tension adjustment components, wherein at least two sliders are provided, at least two printing wheels are provided, and at least one printing wheel is installed on each slider, and the sliders are slidably connected to the mounting plate;

[0009] The tension adjustment assembly is mounted on the slider and is used to adjust the clamping force of the printing wheel on the cable.

[0010] By adopting the above technical solution, the cable is located between the two printing wheels. The two sliders are tightened by the tension adjustment component, thereby clamping the cable between the two printing wheels.

[0011] Preferably, the tension adjustment assembly includes a first side ear, a tension adjustment member, a second side ear, and a tension adjustment screw; the first side ear is connected to one of the sliders, the second side ear is connected to the other slider, the tension adjustment screw is threadedly connected to the second side ear, the tension adjustment member is located between the first side ear and the tension adjustment screw, and the tension adjustment member connects the first side ear and the tension adjustment screw.

[0012] By adopting the above technical solution, when printing on cables with a smaller diameter, the two sliders need to be tightened to ensure that the printing wheels can effectively print the text on the cable; when printing on cables with a larger diameter, the two sliders need to be loosened to reduce the clamping of the cable by the two printing wheels, which would cause the text to be printed too deeply or the cable to be squeezed and deformed.

[0013] Preferably, the tension adjusting element is a tension spring.

[0014] By adopting the above technical solution, when it is necessary to adjust the clamping force of the two printing wheels on the cable, simply rotate the tension adjustment screw to continue tightening or loosening the tension adjustment component set between the two sliders.

[0015] Preferably, a cooling mechanism is provided above the printing mechanism, the cooling mechanism including a shower head and a water inlet pipe; the water inlet pipe is located at the upper end of the mounting plate, the shower head is connected to one end of the water inlet pipe, and the shower head is located above the printing wheel.

[0016] By adopting the above technical solution, the cooling mechanism is used to cool the printed cable. The shower head is located above one side of the two printing wheels. The purpose of this design is to prevent the coolant sprayed from the shower head from splashing onto the printing wheels and thus affecting the printing effect.

[0017] Preferably, the mounting plate has a water tank with a drain outlet, and a drain pipe is connected to the mounting plate, the drain pipe being connected to the drain outlet.

[0018] By adopting the above technical solution, the coolant sprayed from the showerhead cools the cable and falls into the water tank, and the coolant in the water tank is then discharged from the water tank through the drain outlet and drain pipe.

[0019] Preferably, a lifting mechanism is provided below the printing mechanism. The lifting mechanism includes a second support column, a lifting screw, a prism block, a mounting cover, and a lifting actuator. The upper end of the lifting screw is connected to the mounting plate, and the prism block is connected to the lower end of the lifting screw. The lifting screw is slidably connected to the second support column through the prism block. The lifting actuator is located between the mounting plate and the second support column and is used to drive the lifting screw to move up and down. The mounting cover is installed on the upper end of the second support column and is used to limit the movement of the lifting actuator.

[0020] By adopting the above technical solution, the lifting mechanism is used to lift the printing mechanism to adapt to the processing requirements; the lifting mechanism is mainly used to set the printing wheel at the same height as the cable to ensure that the text printed on the cable by the printing wheel is clear and complete. If the printing wheel and the cable are not at the same height, the text printed on the cable will be incomplete or the text will not be printed on the cable.

[0021] Preferably, the lifting actuator includes a lifting mating block, a toggle rod, and a support rod; the support rod is fixedly connected to the lifting mating block, the lower end of the support rod abuts against the upper end of the second support column, the upper end of the support rod abuts against the inner top wall of the mounting cover, the mounting cover is provided with a through hole, the upper end of the lifting mating block passes through the through hole provided in the mounting cover, the toggle rod is connected to the upper end of the lifting mating block; the lifting mating block is threadedly connected to the lifting screw.

[0022] By adopting the above technical solution, when it is necessary to adjust the height of the printing wheel, the lifting engagement block is rotated inside the mounting cover by rotating the lever. The lifting engagement block is connected to the lifting screw through the lifting threaded hole. The lower end of the lifting screw is connected to the lifting groove in the second support column through the prism block. When the lifting engagement block rotates, the lifting screw moves along its own axis and drives the mounting plate and the components set on the mounting plate to rise and fall.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By setting up the cleaning component, impurities on the side wall of the printing wheel can be effectively cleaned, reducing the occurrence of unclear or incomplete text printed on the cable, thereby effectively improving the cable qualification rate.

[0025] 2. By setting up a cooling mechanism, the text printed on the cable is effectively reduced from heat deformation, thereby improving the cable's appearance and pass rate.

[0026] 3. By setting up a lifting mechanism, the printing wheel is positioned at the same height as the cable, ensuring that the text printed on the cable by the printing wheel is clear and complete.

[0027] 4. The lifting mechanism effectively reduces the possibility of the two printing wheels clamping the cable too tightly, resulting in the text being printed too deeply on the cable or the cable being squeezed and deformed. Attached Figure Description

[0037] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0038] This application discloses a cable marking device, referring to... Figure 1 It includes a printing mechanism 20, a cooling mechanism 10, and a lifting mechanism 30; the lifting mechanism 30 is installed below the printing mechanism 20, and the cooling mechanism 10 is installed above the printing mechanism 20; the printing mechanism 20 is used to print characters on the surface of the cable, the cooling mechanism 10 is used to cool the cable after printing, and the lifting mechanism 30 is used to lift the printing mechanism 20 to adapt to processing requirements.

[0039] Reference Figure 2 The printing mechanism 20 includes a mounting plate 21, a slide rail 25, a slider 28, a printing wheel 23, a mounting assembly 201, a cleaning assembly 202, and a tension adjustment assembly 203. The outer contour of the mounting plate 21 is rectangular, and the slide rail 25 is fixedly connected to the mounting plate 21. The axis of the slide rail 25 is parallel to the long axis of the mounting plate 21. In this embodiment, two slide rails 25 are installed inside the mounting plate 21, and the two slide rails 25 are respectively close to the two long sides of the mounting plate 21. Two sliders 28 are provided, and the lower end of each slider 28 is provided with a groove corresponding to the slide rail 25. Both sliders 28 are slidably connected to the slide rail 25 through the groove. In this embodiment, two mounting components 201 are provided, each mounted on the upper end of one of the two sliders 28; two cleaning components 202 are provided, one mounted on the left side of the left slider 28 and the other on the right side of the right slider 28; two tension adjustment components 203 are provided, one on the front side and the other on the rear side of the sliders 28. The mounting components 201 are used to mount the printing wheels 23, the cleaning components 202 are used to clean impurities from the sidewalls of the printing wheels 23, and the tension adjustment components 203 are used to adjust the clamping force of the two printing wheels 23 on the cable. In this embodiment, the parts used in the two mounting components 201, the two cleaning components 202, and the two tension adjustment components 203 are identical.

[0040] Reference Figures 2-3Taking the mounting assembly 201 installed on the left slider 28 as an example, the mounting assembly 201 includes a mounting cylinder 27, a support column 211, a support bearing 212, a washer 213, and a fixing nut 214; wherein the lower end of the support column 211 is fixedly connected to the slider 28, the support bearing 212 is connected to the upper end of the support column 211, and the inner ring of the support bearing 212 is interference-fitted with the side wall of the support column 211; the lower end of the mounting cylinder 27 has a blind hole, and the mounting cylinder 27 is fitted onto the support column 211 through the blind hole, and the inner wall of the blind hole is interference-fitted with the outer ring of the support bearing 212; the upper end of the mounting cylinder 27 is fixedly connected to a mounting block 2701, and the upper end of the mounting block 2701 is fixedly connected to the support column 211. A mounting screw 2702 is fixedly connected; the mounting block 2701 is an oblong block, and the printing wheel 23 is provided with a mounting groove that slides with the mounting block 2701. In this embodiment, the mounting groove on the printing wheel 23 is an oblong groove. After the printing wheel 23 is fitted onto the mounting block 2701, it will not rotate on its own. The mounting block 2701 is also equipped with a washer 213. The height of the mounting screw 2702 is greater than the thickness of the printing wheel 23. The fixing nut 214 is threaded onto the mounting screw 2702. After the printing wheel 23 is fitted onto the mounting block 2701, the fixing nut 214 is tightened onto the mounting screw 2702, thereby fixing the printing wheel 23 onto the mounting cylinder 27. The purpose of setting the shim 213 is: when dealing with cables of different diameters, it is necessary to replace the printing wheel 23 with one of different thickness. If the printing wheel 23 is too high or too low than the cable, the printing wheel 23 can be adjusted to be at the same height as the cable by adding or removing the shim 213.

[0041] The slider 28 slides on the slide rail 25 at all times. The purpose of this design is that the cable to be printed is usually in a straight state, and the cable is located between the two printing wheels 23. During the printing process, the cable is transmitted between the two printing wheels 23. When the cable is accidentally touched by the staff or for other reasons, causing the cable to move to the left or right, the slider 28 can move with the cable. This ensures that even if the cable moves to one side during the printing process, the depth of the text printed on the cable is relatively uniform. If the slider 28 is fixed on the mounting plate 21, when the cable moves, the clamping degree between the cable and the two printing wheels 23 on the cable changes, resulting in uneven depth of the text printed on the cable, which affects the aesthetics and pass rate of the cable.

[0042] Reference Figures 2-3Taking the cleaning assembly 202 installed on the left slider 28 as an example, the cleaning assembly 202 includes a brush plate 24, a position adjusting screw 29, and a prism rod 210; the right end of the position adjusting screw 29 is rotatably connected to the left end of the slider 28, and a rotating handle is fixedly connected to the left end of the position adjusting screw 29. In this embodiment, the rotating handle connected to the left end of the position adjusting screw 29 is a triangular block, and the circumscribed circle diameter of the triangular block is smaller than the outer diameter of the lifting screw 32; the right end of the prism rod 210 is fixedly connected to the left end of the slider 28, and the prism rod 210 is located below the position adjusting screw 29. The long axis of 210 is parallel to the axis of the position adjusting screw 29; the axis of the position adjusting screw 29 is parallel to the axis of the slide rail 25. The brush plate 24 is provided with a position adjusting threaded hole that mates with the position adjusting screw 29. The brush plate 24 is also provided with a position adjusting groove that slidably mates with the prism rod 210. The brush plate 24 is connected to the position adjusting screw 29 and the prism rod 210 of the slider 28 through the position adjusting threaded hole and the position adjusting groove, respectively. The side of the brush plate 24 near the printing wheel 23 is provided with an arc-shaped groove, and the arc-shaped groove is also provided with bristles. The bristles are used to clean the side wall of the printing wheel 23.

[0043] During the printing process, the cable is clamped between the two printing wheels 23 and transmitted between them. The cable drives the printing wheels 23 to rotate through the friction between the outer wall and the side wall of the printing wheels 23. The distance between the brush plate 24 and the printing wheels 23 can be adjusted by the position adjusting screw 29. The position adjusting screw 29 is rotated by the rotating handle at one end of the position adjusting screw 29. The brush plate 24 is restricted by the prism 210 and can only move along the axis of the adjusting lifting screw 32. The thread length on the position adjusting screw 29 corresponds to the length of the prism 210. When the brush plate 24 needs to be removed for cleaning or replacement, the position adjusting screw 29 is rotated continuously to disengage the brush plate 24 from the position adjusting screw 29 and the prism. When the brush plate 24 needs to be reinstalled, the position adjusting thread hole and the position adjusting groove on the brush plate 24 are aligned with the position adjusting screw 29 and the prism on the slider 28, respectively. The brush plate 24 is installed on the position adjusting screw 29 and the prism by rotating the position adjusting screw 29.

[0044] Reference Figure 4Taking the tension adjustment assembly 203 installed on the front side of the slider 28 as an example, the tension adjustment assembly 203 includes a first side ear 215, a first connecting block 216, a tension adjustment component 217, a second side ear 218, a tension adjustment screw 219, and a second connecting block 220. The first side ear 215 is fixedly installed on the front end of the left slider 28, and the first connecting block 216 is rotatably connected to the first side ear 215. The second side ear 218 is fixedly installed on the front end of the right slider 28, and the second side ear 218 also has a tension adjustment threaded hole that cooperates with the tension adjustment screw 219. The tension adjustment screw 219 is threadedly connected to the tension adjustment hole of the second side ear 218. Inside the adjusting threaded hole, the second connecting block 220 is fixedly installed at the end of the tension adjusting screw 219 near the left slider 28. In this embodiment, the tension adjusting component 217 is a tension spring, with one end fixedly connected to the first connecting block 216 and the other end fixedly connected to the second connecting block 220. The tension spring is used to adjust the tension between the two sliders 28. The cable is clamped between the two printing wheels 23. The tension spring tightens the two sliders, thereby clamping the cable between the two printing wheels. When it is necessary to adjust the clamping force of the two printing wheels 23 on the cable, the tension adjusting screw 219 is rotated to continue to tighten or loosen the tension spring set between the two sliders 28.

[0045] When printing on cables with a smaller diameter, the two sliders 28 need to be tightened to ensure that the printing wheel 23 can effectively print the text on the cable. When printing on cables with a larger diameter, the two sliders 28 need to be loosened to reduce the clamping of the cable by the two printing wheels 23, which could result in the text being printed too deeply or the cable being squeezed and deformed.

[0046] Reference Figures 5-6The cable temperature is high after the text is printed. To reduce the heat deformation of the printed text on the cable, which would affect the cable's appearance and pass rate, a cooling mechanism 10 is installed on the printing mechanism 20. The cooling mechanism 10 includes a shower head 11, a water inlet pipe 12, a water inlet support rod 13, and a support block 14. A water-holding tank 2101 is provided on the top wall of the mounting plate 21. The support block 14 is fixedly installed on one side wall of the mounting plate 21. The water inlet support rod 13 is fixedly installed on the support block 14 in a vertical direction. The water inlet pipe 12 is fixedly connected to the upper end of the water inlet support rod 13. The water inlet pipe 12 and the water inlet... The support rods 13 are perpendicular to each other, the axis of the water inlet pipe 12 is parallel to the long axis of the mounting plate 21, and the shower head 11 is connected to one end of the water inlet pipe 12. The shower head 11 is located above one side of the two printing wheels 23. The purpose of this design is to prevent the coolant sprayed from the shower head 11 from spraying onto the printing wheels 23 and thus affecting the printing effect. The shower head 11 is rectangular, and the long axis of the shower head 11 corresponds to the sliding direction of the slider 28. The center of the long axis of the shower head 11 is between the two sliders 28. The purpose of this design is to ensure that when the diameter of the cable is large, the coolant sprayed from the shower head 11 can still spray onto the cable. A drain outlet 26 is provided on the bottom wall of the water tank 2101. A drain pipe 22 is fixedly connected to the bottom wall of the mounting plate 21. The drain pipe 22 is connected to the drain outlet 26. The coolant sprayed from the shower head 11 cools the cable and falls into the water tank 2101. The coolant in the water tank 2101 is then discharged from the water tank 2101 through the drain outlet 26 and the drain pipe 22.

[0047] Reference Figure 7The lifting mechanism 30 is mainly used to position the printing wheel 23 at the same height as the cable, ensuring that the text printed on the cable by the printing wheel 23 is clear and complete. If the printing wheel 23 is not at the same height as the cable, the text printed on the cable will be incomplete or not printed at all. The lifting mechanism 30 includes a first support column 31, a second support column 38, a lifting screw 32, a prism block 33, a mounting cover 34, a contact block 36, a fixing plate 37, and a lifting actuator 301. The upper end of the first support column 31 is fixedly connected to the lower bottom wall of the mounting plate 21, the upper end of the lifting screw 32 is fixedly connected to the lower end of the first support column 31, the second support column 38 is located below the first support column 31, and the prism block 33 is fixedly connected to the lower end of the lifting screw 32. A lifting groove that slides along the axis of the second support column 38 in cooperation with the prism block 33 is provided. The lifting screw 32 is slidably connected to the second support column 38 through the prism block 33. The lower bottom wall of the fixed plate 37 is fixedly connected to the upper end of the second support column 38. The lower end of the abutment block 36 is fixedly connected to the upper top wall of the fixed plate 37. The lower end of the lifting actuator 301 abuts against the abutment block 36. The mounting cover 34 is fixedly connected to the fixed plate 37 by fasteners. In this embodiment, the fasteners connecting the mounting cover 34 and the fixed plate 37 are set screws. The lower end of the lifting actuator 301 is restricted between the mounting cover 34 and the fixed plate 37. A through hole is opened on the mounting cover 34. The upper end of the lifting actuator 301 passes through the through hole opened in the mounting cover 34 and is located outside the mounting cover 34. The lifting actuator 301 is used to drive the lifting screw 32.

[0048] Reference Figures 7-8 The lifting actuator 301 includes a lifting mating block 35, a lever 39, a support rod 310, and a rolling element 311. Six support rods 310 are provided and fixedly connected to the lower end of the lifting mating block 35. The six support rods 310 are arranged circumferentially along the axis of the lifting mating block 35. The upper and lower spherical surfaces of the rolling element 311 pass through the support rods 310 in the vertical direction. The lower spherical surface of the rolling element 311 is used to roll on the abutment block 36, and the upper spherical surface of the rolling element 311 is used to roll on the inner top wall of the mounting cover 34. The upper end of the lifting mating block 35 extends upward through the through hole of the mounting cover 34. Two levers 39 are provided and connected to the upper end of the lifting mating block. The two levers are arranged circumferentially along the axis of the lifting mating block 35. A lifting threaded hole connected to the lifting screw 32 is opened at the axis of the lifting mating block 35. When the height of the printing wheel 23 needs to be adjusted, the lifting engagement block 35 is rotated within the mounting cover 34 by rotating the lever. The lifting engagement block 35 is connected to the lifting screw 32 through the lifting threaded hole. The lower end of the lifting screw 32 is connected to the lifting groove in the second support column 38 through the prism block 33. When the lifting engagement block 35 rotates, the lifting screw 32 moves along its own axis and drives the mounting plate 21 and the components set on the mounting plate 21 to rise and fall.

[0049] The implementation principle of the cable printing device in this application embodiment is as follows: When the printing wheel 23 is printing on the cable, the printed cable is then cooled by spraying water from the shower head 11 in the cooling mechanism 10. If this batch of cables has been printed and another batch of cables needs to be replaced, the printing wheel 23 is replaced according to the printing requirements of the cable. When installing the printing wheel 23, the printing wheel 23 is set at the same height as the cable by appropriately adding shims 213, or the printing wheel 23 is adjusted to the same height as the cable by lifting screw 32. Then, the clamping force of the printing wheel 23 on the cable is checked. If the clamping force of the printing wheel 23 on the cable is too tight or too loose, it can be adjusted by rotating the tension adjustment screw 219. Then, the distance between the brush plate 24 and the printing wheel 23 is checked. If the distance between the brush plate 24 and the printing wheel 23 needs to be adjusted, it can be adjusted by rotating the position adjustment screw 29. Finally, the cable is transmitted, and the printing wheel 23 prints on the cable.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
