Description

Technical Field

[0001] The utility model relates to a printing machine, in particular to a scraper assembly and a feeding mechanism with the scraper assembly. Background Art

[0002] A printing press is a mechanical device used to print text, patterns, images, etc. on paper, cloth, plastic or other materials. It is widely used in publishing, packaging, advertising, and the identification and decoration of various industrial products. With the advancement of technology, printing presses have evolved from traditional manual operation to automation, digitization and even intelligence.

[0003] The printing machine includes a feeding mechanism, and the feeding mechanism mainly refers to the feeding operation of two materials, ink and glue. The feeding mechanism includes a scraper assembly, which is used to ensure that the material is evenly distributed on the roller body, thereby ensuring the uniformity of material transmission. The existing scraper assembly includes a knife seat, a knife plate, a scraper arranged between the knife seat and the knife plate, a limiting structure formed between the knife seat and the knife plate, a clamping groove formed between the knife seat and the knife plate, and an eccentric pressure rod inserted into the clamping groove. The eccentric clamping pressure generated by rotating the eccentric pressure rod cooperates with the limiting structure to form the knife seat and the knife plate to press and fix the scraper. However, since the clamping contact surfaces of the clamping groove and the eccentric pressure rod are both arc-shaped surfaces, the contact surface between the two is small. In addition, affected by the curvature between the two arc-shaped surfaces, it is easy to cause excessive or too small local pressure, thereby affecting the overall clamping effect, resulting in this structure being very easy to loosen when subjected to vibration, affecting the firmness of the scraper installation. Utility Model Content

[0004] The utility model aims to provide a scraper assembly, which can improve the firmness of scraper installation, thereby ensuring the processing accuracy and processing quality of equipment.

[0005] The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: a scraper assembly, including: a blade seat, configured to provide a foundation for installation; a blade plate, configured to cooperate with the blade seat; a scraper, arranged between the blade seat and the blade plate and used to scrape the coating body; a limiting structure, configured to constitute a limiting cooperation between the blade seat and the blade plate; a clamping groove, formed between the blade seat and the blade plate; an eccentric fixing pin, configured to be inserted into the clamping groove and cooperate with the limiting structure to constitute the blade seat and the blade plate to press and fix the scraper, and the contact position between the clamping groove and the eccentric fixing pin includes a clamping arc surface and a clamping plane that are pressed against each other.

[0006] By adopting the above technical solution, the pressing contact position between the pressing groove and the eccentric fixing pin is set to a contact mode between a pressing arc surface and a pressing plane. Since this contact mode has a large contact area and a relatively uniform distribution, the pressure transmission can be more stable; thereby improving the firmness of the scraper installation and preventing loosening, thereby ensuring the processing accuracy and processing quality of the equipment.

[0007] It is further configured that: the abutting arc surface and the abutting plane are formed between the knife seat and the eccentric fixing pin and / or between the knife plate and the eccentric fixing pin.

[0008] By adopting the above technical solution, a stable contact is formed between the two, ensuring that they reach an optimal firmly fixed state.

[0010] By adopting the above technical solution, the design of the insertion notch makes the shape of the eccentric fixing pin adapt to the shape of the abutting groove, so that the eccentric cylindrical pin can be smoothly inserted into the abutting groove without causing structural interference due to the existence of the abutting plane. This arrangement can also reduce the assembly gap formed between the two to ensure the firmness of the later abutment.

[0011] It is further configured that: the limiting structure includes a limiting groove and a limiting block inserted into the limiting groove, and the eccentric fixing pin abuts against the tightening groove to drive the limiting groove and the limiting block to abut against each other.

[0012] By adopting the above technical solution, the eccentric fixing pin abuts against the tightening groove to drive the limiting groove and the limiting block to abut against each other, thereby realizing the abutting and fixing of the knife seat and the knife plate, and achieving the purpose of fixing the scraper.

[0013] It is further configured as follows: the limiting groove includes a first connecting section with an opening and a second limiting section connected to the first connecting section, the first connecting section and the second limiting section are not parallel, and the limiting block extends into the first connecting section and the second limiting section in sequence.

[0014] By adopting the above technical solution, the limit groove is set to a first connecting section and a second limit section structure and the second limit section and the first connecting section are set to be non-parallel, so that the limit groove and the limit block can play a more stable structural clamping role after being subjected to mutual clamping force, thereby improving the stability of the structure.

[0015] It is further configured that: both ends of the eccentric fixing pin are provided with docking pieces for driving the eccentric fixing pin to rotate.

[0016] By adopting the above technical solution, the setting of the docking piece makes it easy to drive the eccentric fixing pin to perform rotational locking operation, making the operation more convenient.

[0017] Another object of the present invention is to provide a feeding mechanism, which can improve the feeding quality and the feeding quality.

[0018] The above technical purpose of the utility model is achieved through the following technical solutions: a feeding mechanism, comprising: a mounting seat and two groups of scraper assemblies arranged on the mounting seat, a feeding chamber is formed between the two groups of scraper assemblies, the feeding chamber is connected to a feed port and a discharge port, and a flow regulating member is provided on the discharge port.

[0019] By adopting the above technical solution, the discharge flow rate is adjusted by the provided flow regulating member, thereby controlling the capacity of the material body in the feeding chamber, thereby achieving the purpose of controlling the feeding amount.

[0020] It is further configured as follows: there are at least two discharge ports and each discharge port is provided with the flow regulating member, a material box for receiving the material output from each discharge port is provided below the discharge port, and the material box is isolated from the outside world by the scraper assembly on the side opposite to the upper material cavity opening.

[0021] By adopting the above technical solution, the isolation installation setting structure can minimize the probability of the material in the material box contacting the outside world to the greatest extent, to avoid secondary contamination of the material during use, thereby ensuring the quality of the material during the processing.

[0022] It is further configured as follows: it comprises a material barrel connected to the material box, and the material barrel is connected to the feed port through a diaphragm pump.

[0023] By adopting the above technical solution, the diaphragm pump is combined with the material barrel to realize the recycling of the material.

[0024] It is further configured as follows: the scraper assembly is detachably fixedly connected to the mounting seat, and the detachable fixed connection includes a hanging groove arranged on the mounting seat and a hanging rod fixedly arranged on the scraper assembly.

[0025] By adopting the above technical solution, the disassembly, assembly and maintenance of the scraper assembly are facilitated.

[0026] In summary, the utility model has the following beneficial effects: the utility model can improve the firmness of the scraper installation, thereby ensuring the processing accuracy and processing quality of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS
