[0033] The present invention will be described in further detail below through specific embodiments in conjunction with the accompanying drawings.

[0034] See Figures 1 to 3The scraper for cleaning the guide belt provided in this embodiment includes an elastic support assembly 100, a scraper assembly 200 and a guide assembly 300. The elastic support assembly 100 includes a support seat 110 and an elastic member 120. The support member is used to support the scraper assembly 200. The elastic member 120 is arranged below the support seat 110 and abuts against the support member. The scraper assembly 200 is arranged on the support seat 110. The scraper assembly 200 includes an obliquely arranged plastic blade body 210. The top of the plastic blade body 210 is used to abut against the surface of the guide belt. The guide assembly 300 includes a guide portion extending in a vertical direction, and the scraper assembly 200 cooperates with the guide portion.

[0035] The elastic support assembly 100 is capable of mounting and supporting the scraper assembly 200. When the scraper assembly 200 is mounted on the elastic support assembly 100, the tip of the plastic blade 210 abuts and maintains contact with the support surface of the guide belt. As the guide belt is being conducted and moved, the tip of the plastic blade 210 scrapes away water stains and impurities from the support surface.

[0036] During scraping, if the interaction force between the guide belt and the plastic blade body 210 is too large, the scraper assembly 200 moves downward under the action of the force to compress the elastic member 120, thereby preventing the plastic scraper from contacting the guide belt for scraping. The interaction force between the two is too large, causing damage to the placing surface of the guide belt, or the plastic scraper cannot be used due to severe wear.

[0037] In this embodiment, the elastic support assembly 100 further includes a mounting base 130 and a stopper. The mounting base 130 is provided with screw holes for connecting to the device, and the elastic member 120 is disposed on the mounting base 130. The stopper is disposed on the mounting base 130, extends in a vertical direction, and is inserted into and penetrates the elastic member 120 in the vertical direction.

[0038] After the limiting member is inserted into and penetrates the elastic member 120, it can limit the compression direction of the elastic member 120. When the elastic member 120 is compressed, the compression direction of the elastic member 120 can remain the same as the extension direction (i.e., the vertical direction) of the limiting member, thereby preventing the elastic member 120 from being offset when compressed, causing the scraper assembly 200 to move horizontally, and making it impossible for the top end of the plastic scraper to continuously contact the placement surface of the guide belt to perform a scraping action.

[0039] In this embodiment, the elastic member 120 is a spring. The limiting member is a limiting rod, which is disposed within the spring. There are multiple springs and multiple limiting rods, each of which is provided in a one-to-one correspondence and is evenly arranged along the circumference of the mounting seat 130.

[0040] Specifically, the spring in this embodiment is a compression spring, and a limiting rod is inserted into the inner coil of the compression spring, thereby preventing the compression spring from deflecting horizontally during compression. In this embodiment, the top of the limiting rod penetrates the support seat 110, and a limiting nut is mounted on the end of the limiting rod above the support seat 110 to prevent the support seat 110 from falling off the top of the limiting rod under the action of the spring. In this structure, when the guide belt presses downward, causing the scraper assembly 200 to move downward, the scraper assembly 200 is pressed downward by the force, causing the support seat 110 to move downward along the limiting rod, thereby compressing the compression spring.

[0041] In this embodiment, there are multiple elastic support components 100 , which are spaced apart along the extending direction of the scraper component 200 .

[0042] Among them, the multiple elastic support members in this embodiment are evenly and spaced apart, which can achieve stable support for the scraper assembly 200 and ensure that all parts of the plastic scraper can abut against the placement surface of the guide belt, avoiding the plastic scraper from falling to one side when it is too long and resulting in inability to fully contact the guide belt.

[0043] In this embodiment, the scraper assembly 200 further includes a fixing base 220. The fixing base 220 extends in a horizontal direction and is provided with a mounting groove, into which the lower end of the plastic blade body 210 is inserted.

[0044] The fixing seat 220 is used to install the plastic blade 210. Specifically, the fixing seat 220 in this embodiment is made of metal, and a plurality of connection holes are evenly arranged on the fixing seat 220 along its length, and screws can be screwed into the plurality of connection holes to achieve the effect of fixing and locking the plastic blade 210.

[0045] In this embodiment, the plastic blade 210 is a polyurethane scraper.

[0046] Polyurethane materials offer excellent stability, chemical resistance, resilience, mechanical properties, compression set resistance, heat insulation, sound insulation, shock resistance, and toxicity resistance. When scraping the guide belt, the polyurethane scraper can deform slightly, further minimizing damage to the belt.

[0047] In this embodiment, the guide assembly 300 includes two fixing members 310 . The two fixing members 310 are spaced apart from each other, and the guide portions are provided on opposite surfaces of the two fixing members 310 .

[0048] The scraper assembly 200 is arranged between the two fixing parts 310, and the two ends of the scraper assembly 200 cooperate with the guide parts on the two fixing parts 310, so that the scraper assembly 200 can move along the extension direction of the guide part (i.e., the vertical direction), so that the scraper assembly 200 can move downward smoothly when subjected to the pressure of the guide belt.

[0049] The guide assembly 300 in this embodiment further includes a moving member 320. There are two moving members 320, which are respectively disposed at two ends of the scraper assembly 200 and are slidably engaged with the two guide portions.

[0050] Specifically, the two moving members 320 in this embodiment are installed at both ends of the fixed base 220. The fixed base 220 achieves relative sliding with the guide portion through the two moving members 320, thereby driving the plastic blade 210 to move together.

[0051] In this embodiment, the guide portion is a slide groove, and the moving member 320 is disposed in the slide groove.

[0052] The two slide grooves are respectively opened on the opposite surfaces of the two fixed seats 220, and the movable part 320 in this embodiment is a slider, and the two sliders are respectively arranged in the two slide grooves. While realizing the sliding cooperation between the fixed seat 220 and the guide assembly 300, it can also further ensure that the moving direction of the scraper assembly 200 is the vertical direction, that is, the extension direction of the slide groove.

[0053] The inkjet printer provided in this embodiment includes a drive roller, a guide belt, and a guide belt cleaning scraper. The drive roller extends horizontally, and there are multiple drive rollers spaced apart. The inner wall of the guide belt is in contact with the multiple drive rollers for transmission, and the side of the guide belt facing away from the drive rollers serves as a receiving surface. The guide belt cleaning scraper is positioned below the guide belt, with the top end of its plastic blade 210 abutting the receiving surface.

[0054] The elastic support assembly 100 in the scraper for cleaning the guide belt is positioned below the guide belt, and the scraper assembly 200 is positioned above the elastic support assembly 100. The top end of the plastic blade body 210 abuts and maintains contact with the guide belt's storage surface. The guide belt is conducted and moved by the rotation of the drive roller, and the top end of the plastic blade body 210 scrapes water stains and impurities from the guide belt's storage surface. During scraping, if the interaction force between the guide belt and the plastic blade body 210 is too great, the scraper assembly 200 moves downward under the force to compress the elastic member 120, thereby preventing the plastic scraper from contacting the guide belt for scraping due to excessive force between the two, which could damage the guide belt's storage surface or render the plastic scraper unusable due to severe wear.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
