Description

Technical Field

[0001] The utility model relates to the field of parts for printing machinery and equipment, in particular to an adjustable printing machine scraper installation component and a flat screen printing machine comprising the component. Background Art

[0002] Flat screen printing machine is an important production equipment needed by the textile printing and dyeing industry in the process of fabric production and processing. Its working principle mainly includes the following stages: the screen frame rises, the guide belt moves, the auxiliary scraper scrapes back the slurry, the guide belt stops moving, the screen frame falls, and the main scraper performs scraping. This action is repeated over and over again, thus completing the printing process on the fabric surface. In the flat screen printing machine equipment, the flat screen printing machine scraper frame device is a key component of the equipment, which determines the printing quality and production efficiency of the flat screen printing machine.

[0003] The traditional scraper frame device of the flat screen printing machine mainly serves to connect and install the scraper component, which is composed of a scraper bracket, a scraper bracket, a scraper clamp and a scraper. At present, various scraper frame devices are designed accordingly according to various work requirements on the market. A screen device of a printing machine disclosed in the Chinese invention patent application document with application number CN202110852824.1 includes a bracket, a screen body and a scraper assembly, the bracket is a gantry structure, the scraper assembly is arranged below the bracket, the scraper assembly and the bracket are slidably connected by a scraper moving assembly, the screen body is fixed below the scraper assembly by a screen fixing mechanism, and the scraper assembly reciprocates along the surface of the screen body through the scraper moving assembly, and Z-axis adjustment assemblies are provided on both sides of the bracket, and the Z-axis adjustment assembly is fixedly connected to the screen fixing mechanism, and the screen body can be moved in the Z-axis direction through the screen fixing mechanism. For another example, a knitted fabric surface printing device disclosed in the Chinese invention patent application document with application number CN202310496767.7 includes a conveyor, a printing frame is mounted on the top of the conveyor, and moving blocks are symmetrically slidably provided on the sides of the printing frame, a scraper carrier and a steering bar are arranged in parallel between the two moving blocks, the heights of the scraper carrier and the steering bar can be switched synchronously, and the steering bar rotates at an angle during the working stroke or return stroke to match different application scenarios of blowing and replenishing slurry; by arranging a fluff processing structure upstream of the conveyor of the printing frame, the fluff on the surface of the knitted fabric is pre-treated, thereby preventing the fluff on the surface of the knitted fabric from clogging the printing screen in the subsequent printing process; by arranging a rotatable steering bar on the side of the scraper carrier, and symmetrically arranging an air outlet groove and a slurry outlet groove on the steering bar, the angle of the steering bar is synchronously switched by using the working stroke and return stroke of the scraper, thereby solving the problems of slurry replenishment and mesh cleaning of the screen.

[0004] However, the inventors found that in the above-mentioned and similar printing equipment, the scraper brackets are usually located at both ends of the scraper frame device, and the scraper frame is perpendicular to the printing machine platen. According to different usage scenarios and printed fabric products, the scraper material may be selected from natural rubber scrapers, synthetic rubber scrapers, synthetic resin scrapers, etc., and the common point of these scrapers is that they have a certain elastic deformation ability to avoid damage to the fabric. In the actual operation process, it can be found that when the scraping print is not large, the scraper frame is also relatively short, the deformation is not obvious, and the scraping effect can be guaranteed; however, due to the working characteristics of the scraper frame that requires rapid reciprocating movement, a slender rod structure is usually adopted. As the scraping print becomes larger and the scraper frame is correspondingly lengthened, the middle suspended section of the scraper frame is only fixed by the support at the two ends, resulting in a certain degree of drooping deformation, which leads to uneven scraping effects in the center and both sides of the same straight line, which in turn has a negative impact on the scraping effect and reduces the quality of the hanging printing product.

[0005] In view of the above problems, the utility model provides an adjustable printing machine scraper mounting assembly which can adaptively compensate for the local sagging deformation of a relatively slender scraper frame to ensure high-quality scraping effect on the product surface and a flat screen printing machine including the assembly.

[0036] The following specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.

[0037] This solution is achieved through the following technical means:

[0038] Embodiment: In this embodiment, an adjustable printing machine scraper mounting assembly A is provided, which can adaptively compensate for the local sagging deformation of a relatively slender scraper frame to ensure a high-quality scraping effect on the product surface, and a flat screen printing machine including the assembly.

[0039] The adjustable printing machine scraper installation assembly A includes an upright installation connection column 1, a lifting and lowering adjustment mechanism 2 for adjusting the vertical height position of the scraper C below is arranged at the upper part of the installation connection column 1, and a clamping and fixing mechanism 3 for installing and connecting the scraper C is arranged at the lower part of the installation connection column 1.

[0040] Specifically, the upper and lower ends of the mounting connection column 1 are respectively formed with a first threaded connection section 101 and a second threaded connection section 102. The lifting and adjusting mechanism 2 includes a supporting bracket 201 as a base for mounting and connecting other components. Figure 1 In the structure given, the supporting frame 201 can be realized by using a hollow square tube component, and a rotatable lifting adjustment nut 203 is movably installed above the square tube component serving as the supporting frame 201. For example, you can refer to the attached manual Figure 2 The structure given is that a fixing seat 202 is first connected to the upper part of the supporting stent 201 by welding, and the fixing seat 202 is hollow inside and has a mounting hole that passes through from top to bottom. The aforementioned lifting and adjusting nut 203 is fixedly arranged in the hollow chamber inside the fixing seat 202, and its upper and lower end faces are respectively limited and stopped by the upper and lower end faces of the inner chamber of the fixing seat 202, and the lifting and adjusting nut 203 can rotate relative to the fixing seat 202 and the supporting stent 201 connected to the fixing seat 202.

[0041] The first threaded connection section 101 on the aforementioned installation connection column 1 can pass through the aforementioned support frame 201 from bottom to top, and then pass through the aforementioned lifting and adjusting nut 203 through a threaded screwing structure. At the same time, a driving wheel 204 is also sleeved and installed on the outer side of the first threaded connection section 101, which is used to drive the lifting and adjusting nut 203 to rotate relative to the first threaded connection section 101. Under this structure, since the bottom of the installation connection column 1 is connected and fixed with other components, it cannot rotate by itself. Therefore, when the driving wheel 204 drives the lifting and adjusting nut 203 to rotate, the nut will rotate relative to the first threaded connection section 101 and move up and down relative to the axial direction of the first threaded connection section 101. Since the upper and lower end surfaces of the lifting and adjusting nut 203 are stopped and fixed, when the nut itself cannot be lifted and lowered, it will drive the installation connection column 1 that rotates relatively therewith to perform lifting and lowering movements, thereby driving the scraper C clamped at the bottom of the installation connection column 1 to lift and lower movements upward or downward.

[0042] The aforementioned clamping and fixing mechanism 3 comprises a scraper hook member 301 fixedly mounted on the second threaded connection section 102 by screw threading, and a scraper clamping claw frame 302 installed below the scraper hook member 301 for clamping and fixing the scraper C. Figure 3The enlarged partial structural diagram shows that the top of the scraper hook 301 is provided with a threaded hole corresponding to the second threaded connection section 102, and the lower part thereof is provided with an inwardly concave notch from bottom to top, and the inside of the notch is also provided with an inwardly expanding part extending to both sides; corresponding to the notch provided by the scraper hook 301, the top of the scraper clamping claw frame 302 below is provided with an outwardly expanding part extending to both sides. At this time, the connection and fixation between the two parts can be achieved by simply inserting the upper part of the scraper clamping claw frame 302 from the side into the notch on the side of the scraper hook 301 and then pushing it into the box.

[0043] Of course, in order to make the above two parts more tightly connected and fixed, and to facilitate the fixed installation at the bottom for direct contact with the screen and the surface of the product for scraping, the scraper clamping claw frame 302 here can be made of plastic or hard rubber with a certain elasticity. Below the scraper clamping claw frame 302, there are clamping plates 303 extending downward on both sides, and a clamping and fixing cavity 304 for clamping and installing the scraper C is formed between the two clamping plates 303. Then, the scraper C can be inserted between the two clamping plates 303 with a certain elastic deformation ability, and the scraper C can be clamped and fixed by using the inward resetting force generated by the two clamping plates 303 themselves.

[0044] As a preferred embodiment, concave and convex positioning teeth 305 may be formed on the inner wall surface of the clamping plate portion 303 to improve the stability of the clamping and fixing of the scraper C component.

[0045] Furthermore, the problem of the scraper hook member 301 being deflected and loosened relative to the second threaded connection section 102 can be prevented by installing a pair of positioning locking nuts 4 with opposite internal threads on the second threaded connection section 102. Specifically, after the scraper hook member 301 is connected to the second threaded connection section 102 through the threaded screwing structure, the lower positioning locking nut 4 is rotated until it is tightly abutted against the top surface of the scraper hook member 301, and then the other upper positioning locking nut 4 is rotated so that its bottom surface abuts against the top surface of the lower positioning locking nut 4. At this time, the scraper hook member 301 can be provided with a downward pressure force by a pair of nuts with opposite rotation directions, so that the internal threads in the threaded holes are tightly abutted against the external threads on the second threaded connection section 102, generating a greater friction force, and preventing the scraper hook member 301 and the scraper C installed thereunder from shaking or deflecting. Of course, a spacer component 5 can also be installed between the supporting frame 201 and the positioning locking nut 4 to prevent the rigid component from squeezing, colliding and deforming the supporting frame 201 which is difficult to replace and repair during the lifting and adjustment process, thereby improving the service life of the equipment.

[0046] When the aforementioned adjustable printing machine scraper installation assembly A is required to be applied to a flat screen printing machine, a base workbench B fixedly placed on the ground is first required, and on both sides of the base workbench B, a pair of connecting columns 6 extending upward and symmetrically to each other are provided, and the two connecting columns 6 are arranged on both sides of the base workbench B and fixedly connected to the two ends of the supporting bracket 201. The supporting bracket 201 here is in a horizontally placed tubular shape, and the scraper C is also in a horizontally placed long strip shape, and a plurality of the adjustable printing machine scraper installation assemblies A are installed on the supporting bracket 201, and the scraper clamping frame 302 at the bottom of each adjustable printing machine scraper installation assembly A is fixedly connected to the corresponding part on the scraper C component below. At this time, the aforementioned driving wheel 204 can be rotated to drive the mounting connection column 1 to move upward or downward as a whole, thereby adjusting the local vertical height at different positions on the scraper C component in a targeted and adaptive manner, which can not only compensate for the sagging part of the mounting frame and make the printing effect more uniform and accurate, but also can realize the different pattern style requirements at different positions on the surface of the fabric product to be scraped and printed, and realize a variety of scraping and printing effects such as gradient style or three-dimensional texture printing by adjusting the local height of the scraper C.

[0047] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
