Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0034] like Figure 1-3The image shows a screen scraper grinding machine provided in an embodiment of the present invention. It includes a frame assembly, which includes a support frame 101 arranged opposite to each other and connected at the bottom. An electrical control box 102 is located on the bottom side inside the support frame 101, and an operation panel 103 is located above the electrical control box 102. A work platform 104 is mounted on the upper part of the support frame 101. A scraper clamping assembly is located at the front end of the work platform 104. The scraper clamping assembly includes a scraper fixing frame 201. Both ends of the scraper fixing frame 201 are vertically and flexibly mounted on the support frame 101 via shaft connectors 202. A scraper support 203 is provided on the scraper fixing frame 201. Opposing arc-shaped guard plates 205 are provided on both the front and rear sides of the scraper fixing frame 201. The middle of the arc-shaped guard plates 205 is connected by a clamping adjustment component, and the bottom of the arc-shaped guard plates 205 is mounted on the scraper fixing frame 201 via a pin. A grinding assembly is provided on the work platform.

[0035] By incorporating a relatively adjustable clamping mechanism, it enables stable support of the scraper during grinding, facilitating easy adjustment and improving grinding precision: the ground surface meets requirements, significantly enhancing printing quality. High efficiency and automation: reducing manual intervention and increasing production efficiency by over 50%. Safe and environmentally friendly: the dust collection device effectively reduces dust particles, meeting industrial hygiene standards. Simple operation: parameter adjustments are achieved through a visual control panel, reducing operational difficulty.

[0036] Among them, the top front end of the support frame 101 is also provided with a through-beam sensor 106 (but this is not limited to the through-beam sensor 106, it may also be other sensors with similar functions). Its function is to detect the approach of the operator in time during the operation of the equipment, prevent accidental contact, and thus effectively avoid injury to personnel. The through-beam sensor 106 is linked with the grinding assembly, that is, the through-beam sensor 106 is activated when the machine is turned on, so as to maximize the protection.

[0037] Specifically, the front of the support frame 101 is also provided with a front cover 107, which can cover the electrical control box 102. The top plate of the front cover 107 is set on the mounting position 105 and is fixed relatively tightly, ensuring the overall connection stability.

[0038] The frame assembly is primarily constructed using steel pipe welding (however, its construction method is not limited to steel pipe welding and may also include other materials or processes); the mounting position 105 is mainly used to install the lifting mechanism of the clamp, providing it with a stable mounting base; the work platform 104 is specifically used to install the grinding components, ensuring that the grinding head can operate smoothly and stably within the equipment; the operation panel 103 plays a crucial role in controlling the operation of the equipment, allowing operators to perform various operations and settings on the equipment; the electrical box provides a centralized control and protection location for the equipment's electrical system, ensuring that the electrical components of the equipment can operate stably and reliably.

[0039] Among them, an adjusting shaft 204 is inserted through the middle of the arc-shaped guard plate 205, and the opposing adjusting shafts 204 are connected by a clamping adjusting component. The adjusting shaft 204 and the clamping adjusting component are connected by a shaft, and wrenches are provided on both sides of the adjusting shaft 204 located on the front side.

[0040] In one embodiment, in order to accommodate the grinding of different types of scrapers, an irregularly shaped support 206 is provided above the scraper support 203.

[0041] The main function of the scraper clamping assembly is to clamp the scraper. The scraper fixing bracket 201 is specifically designed to clamp and connect with the lifting mechanism to ensure the stability of the scraper during the lifting process. The two arc-shaped guard plates 205 cooperate with each other and are connected by the adjusting shaft 204 to form the entire clamping body, providing a firm clamping force for the scraper. The scraper support 203 is used to support the machine scraper, ensuring the position and posture of the machine scraper during operation. The irregular support 206 is used to clamp special machine scrapers, which can meet the clamping needs of different types of machine scrapers, further expanding the function and application scope of this part.

[0042] The support frame 101 is provided with a mounting position 105, and a clamping lifting mechanism is provided on the mounting position 105. The shaft connector 202 of the scraper fixing frame 201 is fixed to the top of the clamping lifting mechanism, such as... Figure 4 As shown, the clamp lifting mechanism includes a horizontal gear plate assembly 301 fixed on the mounting position 105. The side of the gear plate meshes with the active gear adjusted by the handwheel 304. The gear plate assembly 301 has a threaded sleeve 302. A lifting screw 303 is provided inside the threaded sleeve 302. The shaft connector 202 is installed at the end of the lifting screw 303.

[0043] The work platform 104 has a sprocket 305 located in the middle of the front side, and a chain that passes through the sprocket 305 and connects to the opposite side drive teeth on the handwheel 304 to ensure that the two lifting mechanisms operate synchronously.

[0044] The main function of this part is to realize the lifting and lowering operation of the machine scraper clamp. Specifically, the handwheel 304 is manually driven, acting as a power source to drive the gear assembly 301 to move accordingly. The gear assembly 301 consists of two opposing gear discs, with the driving teeth vertically positioned between them and meshing with them. The movement of the gear assembly 301 causes the threaded sleeve 302 to rotate, which in turn forces the lifting screw 303 to lift and lower. The threaded sleeve 302 is the key part for the actual lifting and lowering. At the same time, the mounting part at the end of the lifting screw 303 serves to support and fix the clamp, providing a stable foundation for the entire lifting and lowering process. Furthermore, through the cooperation of the sprocket 305 and the chain (it is emphasized that this is not limited to sprocket 305 and chain drive; other transmission methods may exist), the lifting assembly at the other end can be effectively controlled to move synchronously, thereby ensuring the smoothness and coordination of the machine scraper clamp during the lifting and lowering process.

[0045] like Figure 5 As shown, the grinding assembly includes a linear slide rail 405 mounted on a working platform 104, a sliding frame 403 mounted on the linear slide rail 405, a grinding head assembly 404 mounted on the sliding frame 403, a grinder 406 mounted on the front side of the grinding head assembly 404, and the sliding frame 403 fixed to the transmission mechanism.

[0046] In the specific structure, the transmission mechanism includes a drive motor 401 set at one end of the linear slide rail 405. The drive end of the drive motor 401 and the other end of the linear slide rail 405 are both provided with synchronous pulleys. The synchronous pulleys are provided with synchronous belts. The sliding frame 403 is clamped and fixed on the synchronous belt by the clamping block 402. The two sides of the transmission mechanism are provided with guard plates 408, and the two ends of the transmission mechanism are also provided with limiters 407.

[0047] Specifically, for convenient dust removal, the guard plate 408 is equipped with a dust removal window 409, which serves as a quick-connect interface for the dust collector. This part mainly undertakes the operation and movement of the grinding head. The drive motor 401 drives the synchronous pulley and synchronous belt (it should be noted that this is not limited to just the synchronous pulley and synchronous belt; other transmission methods may also be used) to transmit power and drive the movement. The grinding head assembly 404 is clamped and fixed by the clamping block 402, and simultaneously cooperates with the linear guide rail to drive the sliding frame 403 to move smoothly. The grinding head assembly 404 is firmly fixed to the sliding frame 403 and moves with it. The limiter 407 acts as a movement limit device for the grinding head assembly 404, accurately limiting its range of motion, ensuring accuracy and facilitating subsequent maintenance. The guard plate 408 is the guard plate 408 of the transmission part, and its function is to prevent accidental injury to the operator during operation. In addition, the grinding wheel of the grinding head assembly 404 is equipped with a guard, which, together with the vacuum cleaner (which is not limited to the vacuum cleaner as a dust handling device, but may also include other similar devices) is combined on the dust removal window 409, can more effectively prevent the spread of dust and provide a safer working environment for the operator.

[0048] Although the present disclosure has been described in detail above with general descriptions and specific embodiments, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, such modifications or improvements made without departing from the spirit of the present disclosure are all within the scope of protection claimed by the present disclosure.
