Description

Technical Field

[0001] The invention belongs to the technical field of cleaning equipment, and in particular relates to cleaning equipment with an adaptive adjustment function. Background Art

[0002] The printing roller is an important part of the printing machine used for embossing, ink mixing, and ink transfer. There are words, patterns, and other patterns engraved on the outer surface of the printing roller. After long-term use, a large amount of dust and ink will be contaminated on its surface, and difficult-to-remove dirt will form in the patterns, which will not only erode the patterns themselves, but also seriously affect the printing quality. Therefore, the printing roller needs to be cleaned at intervals. For this purpose, special cleaning equipment is usually used to reduce the labor intensity of the staff and significantly improve the cleaning efficiency.

[0003] For example, the patent (CN220447476U) discloses a printing plate roller cleaning device, which includes a base, and support side plates are provided at both ends of the top of the base, one side of the support side plate is fixedly connected to the top of the base and one side of the support plate, and the other side of the support side plate is movably installed on the top of the base; by setting the support side plate on one side to be movable, when the printing plate roller is supported and fixed by the two support side plates, it can be more widely applicable to the use of printing plate rollers of different lengths.

[0004] In addition, the patent (CN217553480U) discloses a printing plate roller processing and cleaning equipment, including a water tank, wherein a bidirectional screw is rotatably installed between the inner surfaces of the opposite sides of the water tank near the bottom, and two support plates are symmetrically and slidably installed on the bottom wall of the water tank, and the two ends of the bidirectional screw respectively penetrate the outer surfaces of the two support plates and are threadedly connected thereto; by rotating the rocker, the rocker drives the bidirectional screw to rotate, so that the bidirectional screw drives the support plates threadedly connected to the outer surfaces thereof to move closer or farther away at the same time, so that the distance between the two support plates can be quickly adjusted to the adaptive length of the printing plate roller to be cleaned, thereby supporting printing plate rollers of various sizes.

[0005] As can be seen from the above, the prior art has made relevant improvements on how to adapt to printing rollers of different lengths, which has improved the application scope of cleaning equipment to a certain extent. However, printing rollers of different models are not only different in length, but more importantly, their outer diameters are also different.

DETAILED DESCRIPTION

[0011] Embodiment 1, see Figure 1-Figure 14 .

[0012] A cleaning equipment with adaptive adjustment function includes a working box 1 and a cleaning box 106 located inside the working box 1, support members 107 for supporting a printing roller 8 are arranged on both sides of the internal chamber of the cleaning box 106, a rotating mechanism 3 is arranged on the support member 107 on one side, the rotating mechanism 3 drives the support member 107 opposite thereto to rotate, thereby driving the printing roller 8 to rotate, and a length adjustment mechanism 4 for adjusting the distance between the support members 107 on both sides is arranged on the support member 107 on the other side, a flushing mechanism 2 is arranged on the inner side of the cleaning box 106 in the horizontal direction and is directly opposite to the support member 107, and horizontal sliding mechanisms 5 are arranged on both sides of the cleaning box 106 for pushing the flushing mechanism 2, so that the flushing mechanism 2 is moved close to or away from the support member 107 through the horizontal sliding mechanism 5.

[0013] like Figure 1 As shown, two vertical partitions are arranged in the working box 1 along the length direction, namely, the first partition 101 and the second partition 102, and the internal chamber of the working box 1 is sequentially divided into a first accommodation space 103, a second accommodation space 104 and a third accommodation space 105 by the first partition 101 and the second partition 102. Among them, a cleaning box 106 is arranged at the upper part of the second accommodation space 104, and a cleaning space for placing and cleaning the printing roller 8 is formed in the cleaning box 106.

[0014] The support member 107 includes a first plug 108 and a second plug 109 which are identical and face each other. Taking the first plug 108 as an example, its shape is a truncated cone and its axis extends in the horizontal direction, and its diameter gradually decreases from the outside to the inside. The free ends of the first plug 108 and the second plug 109 are respectively inserted into the limit openings 801 at both ends of the printing roller 8, and the connection is connected by a flat key, so as to support and clamp the printing roller 8.

[0015] The flushing mechanism 2 includes: Figure 6 , Figure 7 The water spray pipe 201 shown has one end of the water spray pipe 201 close to the rotating mechanism 3 as a water inlet end, and the other end of the water spray pipe 201 away from the rotating mechanism 3 as a closed end. A cylindrical flow channel is formed inside the water spray pipe 201. A plurality of fan-shaped nozzles 202 are evenly spaced in the horizontal direction on one side of the water spray pipe 201 facing the support 107. The fan-shaped nozzles 202 are connected to the internal flow channel of the water spray pipe 201. The spraying surfaces of the fan-shaped nozzles 202 are horizontal, and the spraying surfaces of adjacent fan-shaped nozzles 202 partially overlap to form a "crossing area", thereby forming a complete high-pressure spray line.

[0016] like Figure 1 As shown, the rotating mechanism 3 includes a first drive motor 301 located in the first accommodating space 103, the first drive motor 301 is fixedly connected to the first partition 101 through a connecting frame, and the output shaft of the first drive motor 301 is connected to the transmission shaft of the first head 108 through the first reducer 302, thereby realizing power transmission. Among them, the positional relationship and connection relationship between the first drive motor 301, the first reducer 302 and the first head 108 are all prior art, and will not be elaborated here. During cleaning, the first head 108 drives the printing roller 8 to rotate under the action of the rotating mechanism 3, thereby ensuring the effectiveness and uniformity of the cleaning effect.

[0017] The length adjustment mechanism 4 includes a vertical plate 401 located in the third accommodating space 105 and facing the second partition 102. The vertical plate 401 and the second partition 102 can move relative to each other to adjust the interval between the two. Specifically, a support rod 402 perpendicular to the second partition 102 is welded on the side of the second partition 102 facing the vertical plate 401. There are four support rods 402 and they are distributed in a rectangular shape. The free end of the support rod 402 passes through the lower part of the vertical plate 401 and is slidably connected to the vertical plate 401. A sliding sleeve is used at the connection between the two.

[0018] A push rod 403 perpendicular to the plate surface of the vertical plate 401 is welded to the upper part of the vertical plate 401. The push rod 403 passes through the second partition 102 and extends toward the rotating mechanism 3. The second top 109 and the vertical plate 401 are connected by the push rod 403. The connection between the second top 109 and the push rod 403 is a rotation connection. The technical means of the rotation connection are existing technologies and will not be described in detail here. A cylinder 406 is arranged in the second accommodation space 104. The cylinder 406 is located below the cleaning box 106 and is threadedly connected to the second partition 102. The cylinder output shaft 407 passes through the second partition 102 in the horizontal direction and is fixedly connected to the vertical plate 401. The connection between the cylinder output shaft 407 and the vertical plate 401 is located at the center of the four support rods 402. The cylinder output shaft 407 drives the vertical plate 401 toward or away from the second partition 102, and simultaneously drives the second head 109 toward or away from the first head 108, thereby adjusting the interval between the first head 108 and the second head 109 to adapt to printing rollers 8 of different lengths.

[0019] When the distance between the first top head 108 and the second top head 109 is small, the length of the portion of the push rod 403 located in the second accommodating space 104 is large. At this time, the weight of the printing roller 8 itself will form a large reaction force on the push rod 403, which may cause the push rod 403 to bend and deform in severe cases. In this regard, a support unit for supporting the push rod 403 is provided below the second top head 109. Specifically, the support unit includes a cross bar 404 located on both sides of the second top head 109. The two ends of the cross bar 404 are respectively welded and fixed to the first partition 101 and the second partition 102. The push rod 403 and the two cross bars 404 are connected by a connecting member 405. In this embodiment, the connecting member 405 is in the shape of a triangular plate. The end of the push rod 403 close to the second top head 109 passes through the top of the connecting member 405 and is clamped and fixed. The two cross bars 404 pass through the bottom of the connecting member 405 and are slidably connected. The support unit can support the push rod 403, effectively preventing the push rod 403 from being deformed due to excessive load, and ensuring that the support members 107 on both sides are always in a facing state.

[0020] Although the printing rollers 8 of different lengths can be adapted by adjusting the spacing between the support members 107 on both sides, the coverage range of the flushing mechanism 2 remains unchanged. Especially when the length of the printing roller 8 is smaller than the flushing range, it is bound to cause waste of resources such as water, solvents and electricity.

[0021] Based on this, the length adjustment mechanism 4 includes a flushing range adjustment unit, such as Fig.10As shown, the flushing range adjustment unit includes a blocking rod 408 that passes through the closed end of the water spray pipe 201 and is slidably sealed and connected to the internal flow channel. The blocking rod 408 is perpendicular to the vertical plate 401 and the fixed end of the blocking rod 408 is fixedly connected to the vertical plate 401. The sealing end of the blocking rod 408 is formed with a plug 409 with the same diameter as the internal flow channel of the water spray pipe 201. The outer periphery of the plug 409 is provided with multiple sealing rings at intervals along the axial direction, thereby improving the sealing effect and preventing leakage between the water spray pipe 201 and the blocking rod 408. The distance between the support members 107 on both sides is adjusted by the length adjustment mechanism 4. In this process, the blocking rod 408 moves synchronously with the length adjustment mechanism 4, so that the blocking rod 408 synchronously adjusts the length of the internal flow channel of the water spray pipe 201 to adjust the spray range, ensuring that the spray range matches the length of the printing roller 8, and can ensure the spray pressure while saving resources such as detergent.

[0022] However, in the actual production process, the length and outer diameter of the printing roller 8 are often different. Then, the cleaning equipment needs to adapt to the length and outer diameter of different types of printing rollers 8. Therefore, on the basis of the above-mentioned length adjustment mechanism 4, a horizontal sliding mechanism 5 for pushing the flushing mechanism 2 is added to adapt to printing rollers 8 with different outer diameters.

[0023] like Fig.11 As shown, the horizontal push mechanism 5 includes sliding plates 501 located on both sides of the water spray pipe 201, and the sliding plates 501 are located in the cleaning box 106. The sliding plates 501 on both sides are parallel to the partitions on both sides and have a gap. A sliding assembly is arranged between the sliding plates 501 and the partitions. The sliding plates 501 can move toward or away from the support member 107 under the action of the sliding assembly. Specifically, taking the sliding plate 501 close to the second partition 102 as an example, a horizontal slide rail 503 is threadedly connected to a side of the sliding plate 501 facing the second partition 102, and a sliding seat 502 adapted to the slide rail 503 is threadedly connected to a side of the second partition 102 facing the sliding plate 501. The slide seat 502 and the slide rail 503 together constitute a sliding assembly. In this embodiment, there are two sets of sliding assemblies, upper and lower.

[0024] The two ends of the water spray pipe 201 are respectively threadedly connected and fixed to the inner plate surface of the sliding plate 501, wherein the end of the water spray pipe 201 close to the first partition plate 101 is the water inlet end, and the water inlet pipe needs to pass through the first partition plate 101 and the sliding plate 501 and then be connected to the water inlet end of the water spray pipe 201. Since the first partition plate 101 and the sliding plate 501 can slide relative to each other along the plate surface, a first transverse slide groove 504 is opened on the first partition plate 101. The first slide groove 504 is oblong, and the water inlet pipe is located in the first slide groove 504 to ensure that the water inlet pipe can slide synchronously with the sliding plate 501.

[0025] The end of the water spray pipe 201 close to the second partition 102 is a closed end, and the blocking rod 408 needs to pass through the second partition 102, the sliding plate 501 and the closed end of the water spray pipe 201 before being slidably and sealedly connected with the internal flow channel of the water spray pipe 201. Similarly, the second partition 102 and the sliding plate 501 can also slide relative to each other along the plate surface, so it is necessary to open a transverse second slide groove 505 on the second partition 102, and the second slide groove 505 is also oblong, and the blocking rod 408 is located in the second slide groove 505, so as to ensure that the blocking rod 408 can slide synchronously with the sliding plate 501.

[0026] In addition, the fixed end of the blocking rod 408 away from the flushing mechanism 2 is fixedly connected to the vertical plate 401 to achieve the transmission of axial force, that is, the fixed end of the blocking rod 408 must be displaced synchronously with the free end on one side of the plug 409. Therefore, a sliding coordination component is provided on the vertical plate 401 to ensure that the two ends of the blocking rod 408 can be displaced synchronously. Specifically, the sliding coordination component includes a transverse rectangular third slide groove 506 opened on the upper part of the vertical plate 401, the third slide groove 506 is directly opposite to the second slide groove 505, and a rectangular slider 507 is slidably connected in the third slide groove 506. The slider 507 is prevented from falling off by the limit baffles on both sides, and the fixed end of the blocking rod 408 is welded and fixed to the slider 507. In addition, an auxiliary rod 508 is connected between the slider 507 and the sliding plate 501, and the auxiliary rod 508 is also located in the second slide groove 505 to ensure the stability of the entire sliding coordination component.

[0027] In addition, if Fig.14 As shown, a transverse fourth slide groove 509 is also formed in the middle of the sliding plate 501, and the fourth slide groove 509 extends outward in a direction away from the flushing mechanism 2 and has an open outer end. The transmission shaft of the tail end 108 of the first plug and the push rod 403 of the tail end of the second plug 109 are respectively located in the fourth slide grooves 509 on both sides, thereby preventing the sliding plate 501 from being obstructed by the above two during the sliding process.

[0028] A driving component is also provided inside the sliding plate 501, and a thrust or a pull is applied to the sliding plate 501 by the driving component, thereby driving the flushing mechanism 2 to move synchronously. Figure 3As shown, the driving assembly includes a second driving motor 510 located in the third accommodating space 105, the second driving motor 510 is fixedly connected to the working box 1 by bolts, and the sliding plates 501 on both sides respectively correspond to a second reducer 511, and the two second reducers 511 are both located on the back of the cleaning box 106 and are respectively fixedly connected to the first partition 101 and the second partition 102 by bolts, wherein the second reducer 511 located on the second partition 102 is connected to the second driving motor 510 by a coupling and the power of the second driving motor 510 is synchronously transmitted to the second reducer 511 on the first partition 101 through the transmission shaft 512, and the output shaft of the second reducer 511 is fixedly connected to the sliding plate 501 by a fixing member.

[0029] An old cleaning agent collection box 6 and a new cleaning agent collection box 7 are also provided below the cleaning box 106. The old cleaning agent collection box 6 is connected to the cleaning box 106, and the old cleaning agent collection box 6 and the new cleaning agent collection box 7 are connected to the water spray pipe 201 through a diverter pump. During the initial cleaning, the old cleaning agent in the old cleaning agent collection box 6 is selected to repeatedly clean the printing roller 8, which fully utilizes the cleaning agent while saving cleaning agent resources. When fine cleaning is required later, the new cleaning agent in the new cleaning agent collection box 7 is selected, and the old cleaning agent formed after flushing the printing roller 8 flows into the old cleaning agent collection box 6 to be reused.

[0030] When in use, first, open the flap on the working box 1, put the printing roller 8 into the cleaning box 106, and according to the length of the printing roller 8, use the length adjustment mechanism 4 to make the spacing between the support members 107 on both sides match the length of the printing roller 8, and insert the support members 107 to clamp and fix the printing roller 8. At the same time, the flushing range adjustment unit synchronously adjusts the internal flow channel length of the water spray pipe 201 according to the spacing between the support members on both sides to adjust the spray range; then, according to the outer diameter of the printing roller 8, use the horizontal push mechanism 5 to adjust the spacing between the printing roller 8 and the fan-shaped nozzle 202 to ensure sufficient and appropriate spray water pressure; finally, turn on the first drive motor 301 and the diversion pump to make the printing roller 8 rotate continuously during the cleaning process to ensure that the printing roller 8 is fully cleaned.

[0031] Finally, it should be noted that the above preferred 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 through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
