Description

Technical Field

[0001] This utility model belongs to the field of pad printing equipment technology, specifically relating to a pad printing device with a dust-adhesive function. Background Technology

[0002] Pad printing machines, as specialized equipment widely used for printing on curved or flat surfaces such as plastics, metals, and ceramics, rely heavily on the cleanliness of the product surface for print quality. During pad printing, any minute impurities (such as dust, fibers, or oil stains) adhering to the product surface can lead to uneven ink transfer, pattern defects, or printing failure. Therefore, an effective dust removal device is a core component for ensuring high-yield pad printing. Existing technologies generally employ cleaning roller structures for surface cleaning, such as the patent with authorization announcement number CN221584836 U, which uses a roller made of adhesive material to adsorb impurities. However, after a period of use, existing cleaning roller structures tend to accumulate dust, reducing their cleaning effectiveness; furthermore, cleaning requires disassembling and replacing the dust-adhesive roller, making the process relatively cumbersome. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a pad printing device with a dust-adhesion function.

[0004] To achieve the above objectives, this utility model discloses a pad printing device with a dust removal function, including a machine body and a pad printing mechanism, a conveying mechanism and a dust removal mechanism disposed on the machine body, wherein the conveying mechanism is provided with a clamp; The dust removal mechanism includes a support, a mounting base, a horizontal drive device, a vertical drive device, and a dust removal roller assembly. The support is mounted on the machine body, and the mounting base is movably mounted on the support. Under the action of the horizontal drive device, the mounting base moves towards and away from the clamp, and under the action of the vertical drive device, the mounting base moves up and down. The dust removal roller assembly includes a dust-adhesive roller and a cleaning roller, which are rotatable on the mounting base. The dust-adhesive roller is located below the cleaning roller, and the cleaning roller has adhesive paper on it. It also includes an elastic element, one end of which presses against the mounting base, and the other end of which presses against the dust roller or cleaning roller, so that the roller surface of the dust roller is in close contact with the roller surface of the cleaning roller.

[0005] Furthermore, the adhesive paper is a tearable adhesive paper.

[0006] Furthermore, both the dust-adhesive roller and the cleaning roller are slidably connected to the mounting base.

[0007] Furthermore, the mounting base includes a first connecting plate and two side mounting plates mounted on both sides of the first connecting plate; The side mounting plate includes a U-shaped frame, a first slider, a second slider, and a top sealing strip. The first slider and the second slider are slidably connected to the inner wall of the U-shaped frame, and the top sealing strip is installed on the top of the U-shaped frame to block the opening of the U-shaped frame. The dust-adhesive roller is rotatably connected to the first slider, and the cleaning roller is rotatably connected to the second slider.

[0008] Furthermore, the first slider is provided with a first shaft hole, and the end of the sticky roller is provided with a first rotating shaft, which is rotatably connected to the first shaft hole.

[0009] Furthermore, the cleaning roller has a connecting hole at its end, and the second slider has a connecting shaft, a bearing, and a connecting cover. The inner ring of the bearing is connected to the connecting shaft, the connecting cover is connected to the outer ring of the bearing, and the connecting cover is engaged in the connecting hole.

[0010] Furthermore, the bottom of the top sealing strip is provided with a locking post, the top of the second slider is provided with a limiting hole, and the two ends of the elastic element are respectively locked in the locking post and the positioning hole.

[0011] Furthermore, the support is provided with a second connecting plate, which is slidably connected to the support, and the horizontal driving device is connected to the second connecting plate; The vertical drive device is mounted on the second connecting plate, and the output end of the vertical drive device is connected to a third connecting plate, with the first connecting plate mounted on the third connecting plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The dust removal roller assembly includes a dust-adhesive roller and a cleaning roller. During the dust removal process, driven by two devices, the dust-adhesive roller rolls on the product surface, thus adhering to and removing dust from the product on the fixture, achieving the dust removal function. As the dust-adhesive roller rotates and adheres to the surface, the cleaning roller, under the action of an elastic element, remains in close contact with the surface of the dust-adhesive roller. Therefore, the cleaning roller also rotates with the dust-adhesive roller, transferring dust from the dust-adhesive roller to the cleaning roller. Even after a period of use, the dust-adhesive roller remains clean, improving the dust removal effect and the reliability of dust removal after prolonged use.

[0013] The cleaning roller uses adhesive paper to remove dust. When the cleaning effect of the cleaning roller decreases, the used adhesive paper can be pulled out and removed, and a new adhesive paper can be applied to the cleaning roller. Once the adhesive paper on the cleaning roller is used up, the cleaning roller can be removed from the mounting base. There is no need to remove the roller from the mounting base every time you clean, making cleaning simpler.

[0014] After removing the old adhesive paper, the size of the cleaning roller decreases. The elastic element maintains the two rollers in close contact, ensuring the cleaning effect of the adhesive roller. Furthermore, the elastic element provides cushioning during contact between the adhesive roller and the product, greatly mitigating damage to the product caused by rigid contact.

Detailed Implementation

[0016] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] A pad printing device with dust-adhesion function, see [link to relevant documentation] Figures 1-4 It includes a machine body 100 and a pad printing mechanism 200, a conveying mechanism 300 and a dust removal mechanism 400 provided on the machine body 100. The conveying mechanism 300 is provided with a clamp 310, which is used for the product to be pad printed.

[0018] The conveying mechanism 300 uses a turntable to transport products by rotating the turntable. The pad printing mechanism 200 is mounted on the machine body 100 and includes a gravure plate, a printing head, etc. The printing head dips the ink from the gravure plate onto its surface and then transfers it to the product to be printed, thereby completing the printing process. In this embodiment, the conveying mechanism 300 and the pad printing mechanism 200 use existing mechanisms, and their specific structures will not be described in detail.

[0019] The dust removal mechanism 400 includes a support 410, a mounting base 420, a horizontal drive device 460, a vertical drive device 470, a dust removal roller assembly 490, and an elastic element 480. The support 410 is mounted on the machine body 100, and the mounting base 420 is movably mounted on the support 410. Under the action of the horizontal drive device 460, the mounting base 420 moves towards and away from the clamp 310, and under the action of the vertical drive device 470, it moves up and down. Through the two drive devices, the dust removal roller assembly 490 can be moved to the corresponding position on the clamp 310, so that the rollers roll on the product surface to remove dust from the product surface.

[0020] The dust removal roller assembly 490 includes a dust-adhesive roller 491 and a cleaning roller 492. Specifically, the dust-adhesive roller 491 and the cleaning roller 492 are a silicone dust-adhesive roller 491 and a portable dust-adhesive paper roller, respectively. The dust-adhesive roller 491 and the cleaning roller 492 rotate on the mounting base 420. The dust-adhesive roller 491 is located below the cleaning roller 492 so as to move and roll along the product surface for cleaning. The cleaning roller 492 has dust-adhesive paper on it. The elastic member 480 is preferably silicon carbide and is mounted on the mounting base 420. One end of the elastic member 480 abuts against the mounting base 420, and the other end of the elastic member 480 abuts against the dust-adhesive roller 491 or the cleaning roller 492. In this embodiment, it abuts against the cleaning roller 492 so that the roller surface of the cleaning roller 492 abuts against the roller surface of the dust-adhesive roller 491.

[0021] During the dust removal process, under the action of two drive devices, the sticky roller 491 rolls on the product surface, thereby sticking away the dust on the product on the fixture 310, thus achieving the dust removal function. During the dust removal process, as the cleaning roller 492 is pressed tightly against the surface of the sticky roller 491 under the action of the elastic element 480, the cleaning roller 492 also rotates with the sticky roller 491. During this process, the dust on the sticky roller 491 is transferred to the cleaning roller 492, so that the sticky roller 491 can remain clean even after a period of use. This improves the dust removal effect and the reliability of dust removal after long-term dust removal.

[0022] The cleaning roller 492 uses adhesive paper to remove dust from the adhesive roller 491. When the cleaning effect of the cleaning roller 492 decreases, the used adhesive paper can be pulled out and removed, for example, by cutting it off. In this embodiment, the adhesive paper is tearable, meaning that the paper inside the adhesive paper is torn off independently. When replacing the adhesive paper, simply tear off the outermost adhesive paper, which is convenient to use. Once the adhesive paper on the cleaning roller 492 is used up, the cleaning roller 492 can be removed from the mounting base 420. There is no need to remove the roller from the mounting base 420 every time you clean, making cleaning simpler.

[0023] After removing one or more old adhesive sheets, the size of the cleaning roller 492 decreases. The elastic element 480 ensures that the two rollers remain in close contact, thus guaranteeing the cleaning effect of the adhesive roller 491. Furthermore, the elastic element 480 provides a cushioning effect during contact between the adhesive roller 491 and the product, greatly mitigating the problem of damage to the product caused by rigid contact between the adhesive roller 491 and the product.

[0024] In this embodiment, both the dust-adhesive roller 491 and the cleaning roller 492 are slidably connected to the mounting base 420. In this way, the cleaning roller 492 can press against the dust-adhesive roller 491 under the action of the elastic member 480, and the dust-adhesive roller 491 can also move to achieve buffering when it comes into contact with the product.

[0025] Specifically, the mounting base 420 includes a first connecting plate 430 and two side mounting plates 440 mounted on both sides of the first connecting plate 430. Each side mounting plate 440 includes a U-shaped frame 441, a first slider 442, a second slider 443, and a top sealing strip 450. Guide strips 4411 are provided on the two inner sidewalls of the U-shaped frame 441, and corresponding sliding grooves 4421 are provided on both sides of the first slider 442 and the second slider 443, allowing them to slide vertically within the U-shaped frame 441. The aforementioned dust-adhesive roller 491 is rotatably connected to the first slider 442, and the cleaning roller 492 is rotatably connected to the second slider 443. The top sealing strip 450 is installed on the top of the U-shaped frame 441 to block the opening of the U-shaped frame 441. On the one hand, it limits the two sliders. On the other hand, the bottom of the top sealing strip 450 is provided with a locking post 451, and the top of the second slider 443 is provided with a limiting hole 4431. The two ends of the elastic element 480 are respectively locked in the locking post 451 and the positioning hole, thereby realizing the assembly of the elastic element 480.

[0026] The locking post 451 is a bolt threaded onto the top sealing strip 450.

[0027] In this embodiment, the first slider 442 is provided with a first shaft hole 4422, and the end of the dust-sticking roller 491 is provided with a first rotating shaft 4911. The first rotating shaft 4911 is rotatably connected to the first shaft hole 4422 to realize the rotatable connection of the dust-sticking roller 491.

[0028] The cleaning roller 492 has a connecting hole 4921 at its end. The second slider 443 has a connecting shaft 444, a bearing 445, and a connecting cover 446. The connecting shaft 444 is fixedly connected to the second slider 443. The inner ring of the bearing 445 is connected to the connecting shaft 444, and the connecting cover 446 is connected to the outer ring of the bearing 445. The connecting cover is engaged in the connecting hole 4921. By setting the bearing 445, the rotational connection of the cleaning roller 492 is achieved, reducing the rotational resistance of the cleaning roller 492, enabling it to rotate smoothly and ensuring the cleaning effect.

[0029] One end of the rotating shaft passes through the second slider 443 and is limited on the second slider 443 by an outer washer 447 and an outer screw 448. A sleeve 449 is fitted onto the connecting shaft 444, and the sleeve 449 abuts against one end of the inner ring of the bearing 445. The other end of the connecting shaft 444 is provided with an inner washer 447 and an inner screw 448. The inner screw 448 is connected to the connecting tube and abuts against the inner washer 447, thereby limiting the inner ring of the bearing 445, and finally realizing the assembly of the bearing 445 and the connecting cover 446.

[0030] In this embodiment, a second connecting plate 411 is provided on the support 410. The second connecting plate 411 is slidably connected to the support 410 via two guide rods 412. The horizontal driving device 460 is a telescopic bar, which is connected to the second connecting plate 411, thereby driving the second connecting plate 411 to move horizontally. The vertical driving device 470 is also a telescopic bar, which is installed on the second connecting plate 411. The output end of the vertical driving device 470 is connected to a third connecting plate 471, and the first connecting plate 430 is installed on the third connecting plate.
