Description

Technical Field

[0001] This utility model relates to a disc typing device, belonging to the technical field of machining equipment. This utility model also relates to a disc typewriter employing the above-mentioned disc typing device. Background Technology

[0002] Currently, most typewriters installed on strip steel processing lines, angle steel processing lines, and channel steel processing lines use a type box design. This type of typewriter can only print a maximum of four strings. To print more types of strings, the type header must be changed, requiring the machine to be stopped, which is time-consuming, labor-intensive, and reduces work efficiency. This existing typewriter structure is unsuitable for processing parts with numerous strings.

[0003] Currently, a disc typewriter has also emerged, in which the prefixes of characters are set on a disc. A drive mechanism drives the disc to rotate, which can rotate the corresponding characters to the stamping position for stamping and typing. For example, Chinese invention patent application CN117901572A discloses a disc coding machine. Its coding machine unit includes multiple coaxially arranged code discs 2. The outer circumferential wall of the code disc 2 is provided with multiple evenly arranged character blocks. It also includes an adjustment mechanism for driving the rotation of the code disc 2. The adjustment mechanism is a synchronous belt drive mechanism. The driven pulley ring 7 of the adjustment mechanism is fixedly connected to one side of the code disc 2. Through each adjustment mechanism, the corresponding code disc 2 can be driven to rotate, thereby rotating the corresponding character block on the code disc 2 to the typing position. However, the multiple character codes 2 of this disc coding machine are coaxially arranged on the supporting main shaft 5. Due to the driven belt pulley ring 7, there is a large gap between two adjacent character codes 2, so the character spacing is relatively wide. During regular typing, the characters in the string need to be separated and typed in two or more times to complete the typing of all the strings. Therefore, it requires a lot of character codes and also increases the configuration of the adjustment mechanism. The typing program of this coding machine unit is cumbersome and costly. Utility Model Content

[0004] In view of the above-mentioned defects in the existing technology, the present invention provides a disc typing device that is simple in structure, convenient to type on, and low in cost.

[0005] This utility model is achieved through the following technical solution: a disc typing device, characterized in that: it includes a bearing shaft and multiple typing discs rotatably mounted on the bearing shaft. Each typing disc includes a sleeve portion and a disc-shaped type mount portion integrally formed with the sleeve portion. Multiple type mounts are evenly spaced on the outer circumference of the type mount portion. At least two typing disc sleeve portions are rotatably fitted together and are coaxially rotatably mounted on the bearing shaft through the sleeve portion of the inner typing disc. The type mount portions of all typing discs are arranged sequentially along the axial direction of the bearing shaft, and adjacent type mount portions are close to each other. Each typing disc is provided with a corresponding drive mechanism for driving its rotation. The drive mechanism is a synchronous belt mechanism. The driven synchronous belt pulley of the synchronous belt mechanism is coaxially fixed to the side of the corresponding typing disc. The drive part of the synchronous belt mechanism is located on the side of the typing disc.

[0006] In this invention, each typing disc can rotate under the drive of its driving mechanism, allowing the corresponding typeface on the typing disc to be rotated to the typing position according to typing needs. By fitting the sleeve parts of the typing discs together, the typeface mounting parts of the typing discs can be made to fit close together, with small gaps between the typeface mounting parts. This allows for sequential typing of strings, eliminating the need for intermittent typing, simplifying the typing process, reducing the number of typing discs, and reducing the configuration of the driving mechanism for rotating the typing discs.

[0007] Furthermore, it includes four typing discs, with the sleeves of two of the typing discs rotatably mounted on the outer sides of the sleeves of the other two typing discs, and the two inner typing discs rotatably mounted on the bearing shaft through their sleeves.

[0008] Furthermore, the number of typing discs that are rotated and assembled together is 2-4.

[0009] Furthermore, it includes three typing discs, two of which are rotatably mounted on the bearing shaft via their sleeve portions, and the third typing disc is fitted onto the outside of the sleeve portion of one of the typing discs mounted on the bearing shaft via its sleeve portion.

[0010] Furthermore, to facilitate the replacement of the typeface, the outer circumference of the typeface mounting part of the typing disk is provided with several grooves, and the typeface is detachably fixed in the grooves.

[0011] Furthermore, to prevent the font from shifting under the impact force during typing, a positioning pin is provided between the bottom of the groove and the bottom of the font.

[0012] Furthermore, to facilitate the installation and fixation of the typefaces, adjacent typefaces are fixed to the typeface mounting part of the typing disc by pressure plates.

[0013] This utility model also provides a disc typewriter using the above-mentioned disc typing device. The technical solution adopted is as follows: a disc typewriter, characterized in that: it includes a base and a typewriter body, the typewriter body is movably mounted on the base, the above-mentioned disc typing device is provided inside the typewriter body, the two ends of the bearing shaft of the disc typing device are fixedly connected to the typewriter body, the driving part of the synchronous belt mechanism of the disc typing device is fixed on the mounting plate, the mounting plate is fixed to the typewriter body, the upper part of the typewriter body is provided with a stamping mechanism corresponding to the disc typing device, the stamping end of the stamping mechanism is connected to a pressure head, and the base is provided with a driving mechanism for driving the typewriter body to move.

[0014] In this invention, the typewriter body can move on the base via a drive mechanism to avoid workpieces or move to the workpiece processing position. The typing disc in the disc typing device can rotate under the drive of its drive mechanism, thereby rotating the corresponding characters on the typing disc to the typing position. When the stamping end of the stamping mechanism is activated, it can drive the pressure head downward to squeeze the workpiece and cooperate with the characters on the typing disc, thereby printing a string on the workpiece.

[0015] Furthermore, to ensure reliable movement of the typewriter body, guide rails are provided on both sides of the base, and rollers are provided on both sides of the lower part of the typewriter body. The typewriter body cooperates with the guide rails on the base through the rollers provided on its lower part.

[0016] Furthermore, to ensure the safe operation of the equipment and to adapt to the typing positions required by workpieces of different specifications, the base is provided with a limiting mechanism to limit the movement range of the typing machine body.

[0017] The beneficial effects of this utility model are as follows: This utility model has a simple structure. The typing disk is driven to rotate by a drive mechanism, which can quickly and conveniently rotate the required printhead to the typing position. By rotating and fitting the sleeve parts of the typing disk together, the printhead mounting parts of all the typing disks can be made to fit together. The gap between the printhead mounting parts of the typing disks is small, and the string can be typed sequentially without the need for intermittent typing, making typing more convenient and the typing program simple. It can also reduce the number of typing disks required. Generally, 3-4 typing disks are sufficient to meet the typing needs. At the same time, it also reduces the configuration of the drive mechanism for driving the typing disk to rotate, which can greatly reduce the equipment cost. Attached Figure Description

[0035] The present invention will be further described below through non-limiting embodiments and in conjunction with the accompanying drawings:

[0036] Example 1

[0037] As attached Figures 1-6As shown, a disc typing device includes a support shaft 2.1, a plurality of typing discs 2.2 rotatably mounted on the support shaft 2.1, and a drive mechanism for driving the typing discs to rotate. Each typing disc 2.2 includes a sleeve portion 2.2.1 and a disc-shaped type mount portion 2.2.2 coaxial with and integrally formed with the sleeve portion 2.2.1. A plurality of type mounts 2.7 are evenly spaced on the outer circumference of the type mount portion 2.2.2. For easy type mount replacement, preferably, a plurality of grooves are provided on the outer circumference of the type mount portion 2.2.2 of the typing disc, and the type mounts 2.7 are detachably fixed in the grooves. To prevent displacement of the type mounts under pressure during typing, it is further preferred that a positioning pin 2.9 is provided between the bottom of the groove and the bottom of the type mount 2.7. To facilitate the installation of the typefaces 2.7, it is further preferred that a pressure plate 2.8 is provided between adjacent typefaces 2.7, and the side of the typeface 2.7 has a stepped surface that contacts the pressure plate 2.8. The two ends of the pressure plate 2.8 are pressed against the stepped surfaces of the two typefaces 2.7 and fixed together with the typeface mounting part 2.2.2 of the typing disc by screws. When replacing the typeface, the pressure plate 2.8 can be removed for easy replacement. When multiple typing discs 2.2 in this utility model are set on the support shaft 2.1, at least two typing discs' sleeve portions 2.2.1 are rotatably fitted together and are coaxially rotatably set on the support shaft 2.1 through the inner typing disc's sleeve portion 2.2.1. Furthermore, the type mount portions 2.2.2 of all typing discs are arranged sequentially along the axial direction of the support shaft 2.1, and adjacent type mount portions 2.2.2 are close together, thereby reducing the gap between the type mount portions 2.2.2 of the typing discs, while each typing disc 2.2 can still rotate. Each typing disc 2.2 is equipped with a corresponding drive mechanism for rotating it. The drive mechanism is a synchronous belt mechanism. The driven synchronous belt pulley of the synchronous belt mechanism is coaxially fixed to the side of the corresponding typing disc. The drive part of the synchronous belt mechanism is located on the side of the typing disc. Under the drive of its drive part, the synchronous belt mechanism drives the driven synchronous belt pulley to rotate through the synchronous belt, thereby driving the typing disc fixed together with the driven synchronous belt pulley to rotate, thus rotating the corresponding prefix 2.7 on the typing disc 2.2 to the typing position.

[0038] The number of typing discs 2.2 in this utility model can be set as needed, and can be 3-8, of which 2-4 are rotating and assembled together, preferably 3-4. (See attached...) Figures 1-6In the disc typing device shown, a total of four typing discs are installed on the support shaft 2.1: typing disc I 2.10, typing disc II 2.12, typing disc III 2.14, and typing disc IV 2.16. The sleeve of typing disc II 2.12 is rotatably fitted onto the outside of the sleeve of typing disc I 2.10, and the head mounting part of typing disc II 2.12 is in contact with the head mounting part of typing disc I 2.10. The sleeve of typing disc III 2.14 is rotatably fitted onto the outside of the sleeve of typing disc IV 2.16, and the head mounting part of typing disc III 2.14 is in contact with the head mounting part of typing disc IV 2.16. The two sets of typing discs fitted together are rotatably mounted on the support shaft 2.1 through the sleeves of typing disc I 2.10 and typing disc IV 2.16, respectively. Each typing disc is equipped with a corresponding synchronous belt mechanism to drive its rotation. There are a total of four synchronous belt mechanisms, each driven by a servo motor and a reducer. The output shaft of the reducer is equipped with a driving synchronous belt pulley. A driven synchronous belt pulley I2.11 is fixed to the outer end of the sleeve portion of typing disc I2.10, a driven synchronous belt pulley II2.13 is fixed to the outer end of the sleeve portion of typing disc II2.12, a driven synchronous belt pulley III2.15 is fixed to the outer end of the sleeve portion of typing disc III2.14, and a driven synchronous belt pulley IV2.17 is fixed to the outer end of the sleeve portion of typing disc IV2.16. Each driven synchronous belt pulley is connected to its corresponding driving synchronous belt pulley via a synchronous belt.

[0039] As attached Figure 7 The diagram shows a disc typing device with three typing discs, including typing disc I 2.10, typing disc II 2.12, and typing disc III 2.14. Typing disc I 2.10 is rotatably mounted on a support shaft 2.1. The sleeve portion of typing disc II 2.12 is rotatably fitted onto the outside of the sleeve portion of typing disc III 2.14 and rotatably mounted on the support shaft 2.1 through the sleeve portion of typing disc III 2.14. The type mounts of the three typing discs are arranged sequentially along the axial direction of the support shaft 2.1, and the three type mounts are sequentially abutted against each other. Each typing disc is also equipped with a corresponding synchronous belt mechanism to drive its rotation. A driven synchronous pulley I2.11 is fixed to the outer end of the sleeve portion of typing disc I2.10, a driven synchronous pulley II2.13 is fixed to the outer end of the sleeve portion of typing disc II2.12, and a driven synchronous pulley III2.15 is fixed to the outer end of the sleeve portion of typing disc III2.14. Each driven synchronous pulley is connected to the driving synchronous pulley of the corresponding synchronous belt mechanism via a synchronous belt. All three typing discs of this disc typing device can rotate under the drive of their respective synchronous belt mechanisms, thereby rotating the corresponding typefaces on the typing discs to the typing device.

[0040] When this utility model is in use, the bearing shaft 2.1 is fixed to the typewriter body. When typing is required, each synchronous belt mechanism drives the corresponding typing disc to rotate through its servo motor and reducer. The corresponding character head on the typing disc is rotated to the typing position to start typing.

[0041] The other parts in this embodiment are all existing technologies and will not be described in detail here.

[0042] Example 2

[0043] As attached Figures 1-14The diagram shows a disc typewriter, comprising a base 1, a disc typing device 2, a typewriter body 3, and a stamping mechanism. The disc typing device 2 is the same as that described in Embodiment 1, and its specific structure will not be repeated here. The base 1 is made of steel plate and shaped steel. The typewriter body 3 is a frame structure consisting of two upright plates and a connecting plate between them. The upright plates have working openings for workpieces to pass through. The disc typing device 2 is installed inside the typewriter body 3. The two ends of the bearing shaft 2.1 of the disc typing device 2 are fixedly connected to the two upright plates on both sides of the typewriter body 3. The reducers of each synchronous belt mechanism of the disc typing device 2 are mounted on the typewriter body 3 via mounting plates 2.6, which are fixedly connected to the typewriter body 3. To facilitate adjustment of the reducers, the reducers are fixed to the mounting plates 2.6 via reducer adjustment plates 2.18. The stamping mechanism, corresponding to the disc typing device 2, is located on the upper part of the typewriter body 3. The stamping mechanism includes a typing cylinder 4 and a pressure head 5 connected to the lower end of the piston rod of the typing cylinder 4. The typing cylinder 4 can drive the pressure head 5 downward to cooperate with the typing disc below for stamping and typing. The typewriter body 3 is movably mounted on the base 1. In this embodiment, guide rails 6 are respectively provided on both sides of the base 1, and multiple rollers 8 are respectively provided on both sides of the lower part of the typewriter body 3. The typewriter body 3 cooperates with the guide rails 6 on the base through the rollers 8 on its lower part. A cylinder 11 is provided on the base 1 to drive the movement of the typewriter body 3. One end of the cylinder 11 is hinged to the base 1, and the other end is connected to the typewriter body. When the cylinder 11 is activated, it can drive the typewriter body 3 to move along the guide rails 6. To ensure safe operation of the equipment and accommodate the typing positions required for workpieces of different specifications, a limiting mechanism is provided on the base 1 to restrict the movement range of the typewriter body 3. This limiting mechanism includes an adjusting screw 7, which is threadedly connected to a connecting plate fixedly mounted at the end of the guide rail 6. One end of the adjusting screw 7 is connected to a handwheel, and the other end is connected to a slotted nut 10. A slider 9 is connected to the typewriter body 3 and slidably mounted on the adjusting screw 7 between the slotted nut 10 and the connecting plate connected to the adjusting screw 7. When the typewriter body 3 moves along the guide rail 6, the slider 9 can only move within the range between the slotted nut 10 and the connecting plate connected to the adjusting screw 7, thus limiting the movement range of the typewriter body 3. According to processing requirements, the distance between the slotted nut and the connecting plate can be adjusted by rotating the adjusting screw 7 to adjust the movement range of the typewriter body.

[0044] The typewriter body 3 in this utility model can be set horizontally or tilted according to processing requirements. In this embodiment, the typewriter body 3 is tilted on the base 1.

[0045] When this utility model is in operation, when the workpiece reaches the typing position, according to the typing command issued by the equipment, each servo motor of the disc typing device 2 works, drives the driven synchronous pulley to rotate through the synchronous belt, and then drives the typing disc fixed to it to rotate through the driven synchronous pulley, rotating the required characters on the typing disc to the typing position. After the required characters on each typing disc are rotated into position, the string is typed. The typing machine body is moved to the workpiece processing position by the hydraulic cylinder 11, and then the typing hydraulic cylinder 4 controls the pressure head 5 to move downward, cooperating with the characters on the typing disc to squeeze and type on the workpiece, thereby printing the string on the workpiece.

[0046] The other parts in this embodiment are all existing technologies and will not be described in detail here.
