Description

Technical Field

[0001] The utility model belongs to the field of digital printing, and in particular relates to an ink scraping component. Background Art

[0002] After a certain period of printing, the digital printing nozzle needs to be cleaned and maintained to improve the printing effect. One of the existing ways to clean the nozzle is to use a flexible scraper to contact the nozzle and scrape off the ink and dust on the nozzle. The scraper first contacts the nozzle and then moves relative to the nozzle to scrape off the ink and dust. In the existing structure, since the contact part between the scraper and the nozzle is flexible, the scraper is usually directly installed on the fixed seat. Since the fixed seat is a fixed structure, when the scraper is worn or deformed after multiple cleaning tasks, the scraper and the nozzle will have poor contact, resulting in poor cleaning effect. Utility Model Content

[0003] The ink scraping assembly provided by the utility model aims to solve the problem in the prior art that poor contact occurs between a scraper blade and a nozzle, resulting in poor cleaning effect.

[0004] The utility model is implemented in this way: an ink scraping assembly comprises:

[0005] Base;

[0006] A floating seat, disposed on the base and movable up and down relative to the base;

[0007] A scraper blade is arranged on the floating seat, and at least the upper end of the scraper blade is made of a flexible material;

[0008] The elastic member is arranged on the base and provides a pre-tightening force to the floating seat to move toward the upper end of the scraper.

[0009] Furthermore, the ink scraping assembly also includes a connecting piece, which passes through the floating seat and the base in sequence and is connected to the base, and the floating seat can move relative to the connecting piece.

[0010] Furthermore, the connecting member includes a connecting portion passing through the floating seat and the base and a limiting portion connected to the connecting portion, the floating seat can move relative to the connecting portion, and the limiting portion can abut against the floating seat under the action of the elastic member.

[0011] Furthermore, the elastic member is a coil spring, the coil spring is sleeved on the connecting portion, the base is provided with a first step abutting against the coil spring, and the floating seat is provided with a second step abutting against the coil spring.

[0012] Furthermore, the scraper blade is fixedly arranged on the outer side of the floating seat.

[0013] Furthermore, a support portion is provided on the outer side of the floating seat, and the bottom of the scraper blade abuts against the support portion.

[0014] Furthermore, the ink scraping assembly further comprises a scraper blade pressing plate, which is attached to a side of the scraper blade away from the floating seat and is fixedly connected to the floating seat.

[0015] Furthermore, the base can be arranged to move up and down, and the ink scraping assembly also includes a driving member for driving the base to move up and down.

[0016] Furthermore, the ink scraping assembly also includes a fixing seat, which is used to be fixed to the maintenance device, the driving member is arranged on the fixing seat, and the driving end of the driving member is connected to the base.

[0017] The beneficial effect achieved by the utility model is that a floating seat that can be moved up and down is set and an elastic member is used to provide a pre-tightening force for the floating member to be away from the base, and then the scraper is fixed on the floating seat. When the scraper contacts the nozzle to clean the nozzle, the elastic member can produce a buffering effect when the scraper contacts the nozzle, thereby avoiding direct hard contact between the scraper and the nozzle, which may cause damage to the nozzle. At the same time, the restoring force of the elastic member after being squeezed by the nozzle can provide the scraper with a force to resist the nozzle, thereby ensuring that the scraper is in good contact with the nozzle, thereby improving the cleaning effect. At least the upper end of the scraper is made of flexible material, which can avoid damage to the nozzle when the scraper contacts the nozzle. At the same time, the upper end made of flexible material can be squeezed and bent when in contact with the nozzle, which can increase the contact area between the scraper and the surface of the nozzle, further improving the cleaning effect.

[0023] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0024] See also Figure 1-Figure 3 The embodiment of the utility model provides an ink scraping assembly, including a base 1, a floating seat 2, a scraper 3 and an elastic member 4. The floating seat 2 is arranged on the base 1 and can move up and down relative to the base 1. The scraper 3 is arranged on the floating seat 2. At least the upper end of the scraper 3 is made of a flexible material, which can be in good contact with the nozzle and prevent the scraper 3 from scratching the nozzle. The elastic member 4 is arranged on the base 1 and provides a pre-tightening force to the floating seat 2 to move toward the upper end of the scraper 3.

[0025] By setting a floating seat 2 that can move up and down and using elastic members 4 to support the floating seat 2

[0026] A pre-tightening force away from the base 1 is provided, and then the scraper 3 is fixed on the floating seat 2. When the scraper 3 contacts the nozzle to clean the nozzle, the elastic member 4 can produce a buffering effect when the scraper 3 contacts the nozzle, avoiding direct hard contact between the scraper 3 and the nozzle, thereby causing damage to the nozzle. At the same time, the restoring force of the elastic member 4 after being squeezed by the nozzle can provide the scraper 3 with a force to resist the nozzle, thereby ensuring that the scraper 3 is in good contact with the nozzle, thereby improving the cleaning effect. At least the upper end of the scraper 3 is made of flexible material, which can avoid damage to the nozzle when the scraper 3 contacts the nozzle. At the same time, the upper end made of flexible material can be squeezed and bent when in contact with the nozzle, which can increase the contact area between the scraper and the nozzle surface, further improving the cleaning effect.

[0027] The ink scraping assembly provided by the utility model can avoid damaging the nozzle during the process of cleaning the nozzle and can also keep the scraper 3 in good contact with the nozzle at all times, thereby improving the cleaning efficiency.

[0028] It should be noted that the upper end of the scraper 3 refers to the portion of the scraper 3 that contacts the nozzle and the area slightly extending outward from the portion. The scraper 3 can be made of a flexible material only at the upper end, and the rest of the scraper 3 can be made of a rigid material, such as hard rubber. In addition, the entire scraper 3 can be made of a flexible material, which can reduce the difficulty of production and improve production efficiency. In this embodiment, the flexible material can be, but is not limited to, silicone.

[0029] See also Figure 2Specifically, the upper surface and the side surface of the scraper 3 are smoothly transitioned by an inclined surface or a curved surface 3a, and the side surface is the side facing the moving direction of the nozzle. When in use, the scraper 3 moves relative to the nozzle to scrape away the residual ink and dust in the part to be cleaned in the nozzle in a translational motion. Specifically, the nozzle can move or the scraper 3 can move. Therefore, the scraper 3 is provided with an inclined surface or a curved surface 3a. When the scraper 3 contacts the nozzle, the inclined surface or the curved surface 3a contacts the nozzle first, which can increase the contact area between the scraper 3 and the nozzle, thereby improving the cleaning effect.

[0030] See also Figure 1-Figure 2 Furthermore, the ink scraper assembly also includes a connecting member 5, which passes through the floating seat 2 and the base 1 in sequence and is connected to the base 1 to prevent the floating seat 2 from separating from the base 1. The floating seat 2 can move relative to the connecting member 5 to avoid the connecting member 5 interfering with the up and down movement of the floating seat 2. At the same time, the connecting member 5 can also guide the movement of the floating seat 2.

[0031] See also Figure 2 Furthermore, the connecting member 5 includes a connecting portion 51 that penetrates the floating seat 2 and the base 1 and a limiting portion 52 connected to the connecting portion 51. The floating seat 2 can move relative to the connecting portion 51. Under the action of the elastic member 4, the limiting portion 52 can abut against the floating seat 2. The limiting portion 52 can prevent the floating seat 2 from separating from the base 1.

[0032] See also Figure 2 Specifically, the floating seat 2 is provided with a hole 11 through which the connecting portion 51 can pass. The inner diameter of the hole 11 is larger than the connecting portion 51 so that the floating seat 2 can move up and down relative to the connecting portion 51. The connecting portion 51 passes through the hole 11 and can make the limiting portion 52 abut against the surface of the floating seat 2 under the action of the elastic member 4, that is, the limiting portion 52 covers one end of the hole 11. The base 1 is provided with a connecting hole 22, and the connecting member 5 is connected and fixed to the connecting hole 22. In this embodiment, the connecting hole 22 can be a threaded hole, the connecting portion 51 can be threadedly connected to the threaded hole, and the connecting member 5 can be, but not limited to, a shoulder screw.

[0033] See also Figure 2, further, the elastic member 4 is a coil spring, and the coil spring is sleeved on the connecting portion 51. The connecting portion 51 can install the coil spring and support the coil spring to avoid deformation during extrusion, thereby affecting the performance. The base 1 is provided with a first step 12 that abuts against the coil spring, and the floating seat 2 is provided with a second step 23 that abuts against the coil spring. The first step 12 and the second step 23 can limit the two ends of the coil spring to avoid displacement of the ends of the coil spring during extrusion, thereby causing noise. Specifically, the first step 12 is set on the inner wall of the hole 11, and the second step 23 is set on the inner wall of the connecting hole 22, that is, one end of the coil spring extends into the hole 11 and abuts against the first step 12, and the other end extends into the connecting hole 22 and abuts against the second step 23. In this way, the hole 11 and the connecting hole 22 can wrap the outside of part of the coil spring to improve the stability of the installation structure of the coil spring.

[0034] See also Figure 2 Furthermore, the scraper blade 3 is fixedly arranged on the outside of the floating seat 2. Compared with the scraper blade 3 being arranged inside the floating seat 2, the scraper blade 3 being arranged on the outside of the floating seat 2 can reduce the complexity of the processing of the scraper blade 3 installation structure of the floating seat 2 and improve production efficiency.

[0035] See also Figure 3 Furthermore, a support portion 21 is provided on the outer side of the floating seat 2, and the bottom of the scraper blade 3 abuts against the support portion 21. The support portion 21 can support the scraper blade 3, and after long-term use, the scraper blade 3 can be prevented from moving toward the base 1 (i.e., away from the upper end of the scraper blade 3) to cause poor contact between the scraper blade 3 and the nozzle.

[0036] See also Figure 3 Furthermore, the ink scraper assembly also includes a scraper blade pressing plate 6, which is attached to the side of the scraper blade 3 away from the floating seat 2 and is connected and fixed to the floating seat 2. The scraper blade pressing plate 6 can press the scraper blade 3 tightly and fix it on the floating seat 2, thereby increasing the contact area between the scraper blade 3 and the floating seat 2 and improving the connection stability.

[0037] See also Figure 1-Figure 2 The base 1 can be moved up and down, and the ink scraping assembly also includes a driving member 7 for driving the base 1 to move up and down. In this way, the ink scraping assembly can be driven to move up and down as a whole by the driving member 7 driving the base 1 to move up and down, so that the scraper 3 can be lifted to the working position or withdrawn from the working position according to the needs. When the ink scraping assembly and other nozzle cleaning and maintenance components are used at the same time, it can be operated according to the cleaning needs of different nozzles to decide whether to use the ink scraping assembly for cleaning, thereby improving the cleaning flexibility for different nozzles of different equipment.

[0038] See also Figure 1-Figure 2Furthermore, the ink scraping assembly also includes a fixed seat 8, which is used to be fixed to other platforms, specifically a cleaning and maintenance platform. The ink scraping assembly is fixed to other platforms through the fixed seat 8. The driving member 7 is arranged on the fixed seat 8, and the driving end of the driving member 7 is connected to the base 1 to drive the base 1 to move up and down.
