Description

Technical Field

[0001] This utility model relates to the field of printing press technology, and in particular to a water-cooled dampening liquid flow-blocking device for printing presses. Background Technology

[0002] Printing presses are widely used in industrial printing fields such as packaging and labeling.

[0003] In the current printing press production process, the temperature control of the rollers is crucial to print quality. Many current machines use flowing water tanks to cool the rollers. The cooling water in the tank circulates, absorbing heat from the rollers and maintaining a stable operating temperature. However, existing technologies have the following problems: The fixed cooling water circulation length results in poor adaptability. When printing products of different sizes, the heated areas of the rollers vary, but the fixed circulation path of traditional water tanks leads to insufficient or excessive cooling in some areas, affecting printing accuracy and energy efficiency. Furthermore, the temperature control precision is insufficient. Because the water flow cannot be flexibly adjusted, locally high-temperature areas may not be effectively cooled, leading to uneven thermal expansion of the rollers and affecting printing registration and ink transfer.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a water-cooled dampening liquid flow-blocking device for a printing press, comprising a water tank, wherein a water control component is provided inside the water tank.

[0006] In a preferred embodiment, the water control assembly includes a threaded rod rotatably mounted on one side of the water tank. An interceptor plate is slidably disposed inside the water tank. Two connectors are fixedly mounted on the upper side of the interceptor plate, one of which is threaded onto the outer surface of the threaded rod.

[0007] The technical effect of adopting the above-mentioned further solution is that the position of the drive interceptor plate inside the water tank can be adjusted, thereby adjusting the circulation length of the water in the water tank.

[0008] In a preferred embodiment, the water control assembly further includes a telescopic rod, which is fixedly installed on one side of the outer surface of the water tank, and the drive end of the telescopic rod is fixedly installed on one side of the connector.

[0009] The technical effect of adopting the above-mentioned further solution is that the connecting parts can be driven by the telescopic rod, thereby pushing the interceptor plate to move within the water tank.

[0010] In a preferred embodiment, a motor is fixedly mounted on one end of the threaded rod, and the motor is fixedly mounted on one side of the water tank.

[0011] The technical effect of adopting the above-mentioned further solution is that by driving the threaded rod with a motor, the moving efficiency of the interceptor plate can be improved.

[0012] In a preferred embodiment, a sealing strip is fixedly installed on the outer surface of the interceptor plate, and the sealing strip is made of silicone.

[0013] The technical effect of adopting the above-mentioned further solution is that by setting a sealing strip on the outer surface of the interceptor plate, it can be ensured that the interceptor plate will not leak water when it slides.

[0014] In a preferred embodiment, the height of the interceptor plate is slightly lower than the height of the water tank, and an overflow channel is formed on the upper side of the interceptor plate.

[0015] The technical effect of adopting the above-mentioned further solution is that the overflow channel allows some water to flow through the interceptor plate, thus avoiding pressure buildup in front of the interceptor plate.

[0016] In a preferred embodiment, a slide bar is fixedly installed on the other side of the water tank, and another connecting member is slidably disposed on the outer surface of the slide bar.

[0017] The technical effect of adopting the above-mentioned further solution is that by fitting another connecting piece onto the outer surface of the slide bar, the stability of the interceptor plate during movement can be improved.

[0018] In a preferred embodiment, one end of the water tank is provided with a water inlet, and the other end of the water tank is provided with a water outlet.

[0019] The technical effect of adopting the above-mentioned further solution is that water is filled into the water tank through the inlet and discharged from the outlet, thus realizing water circulation.

[0020] In a preferred embodiment, the water tank has a second water outlet in the middle.

[0021] The technical effect of adopting the above-mentioned further solution is that when the interceptor plate blocks the middle of the water tank, the path of the water in the water tank will be shortened, and it can then be discharged through the second outlet.

[0022] In a preferred embodiment, a scale is provided on one side of the water tank.

[0023] The technical effect of adopting the above-mentioned further solution is that the ruler facilitates precise operation by the operator, enabling precise temperature control.

[0024] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0025] In use, this invention allows the connecting parts to be driven by both a motor and a telescopic rod. The connecting parts enable the interceptor plate to slide within the water tank, thus altering the water flow path based on the plate's position. When cooling wide-width products, the large heating area of ​​the rollers allows for a shorter water circulation path, achieving efficient cooling. When cooling narrow-width products, the concentrated localized heat allows for a longer cooling path, resulting in slower cooling. This allows the device to achieve precise cooling for products of different widths. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Example 1, please refer to Figures 1 to 3This utility model provides a technical solution: a water-cooled dampening liquid flow-blocking device for a printing press, including a water tank 100. A water control component is installed inside the water tank 100, including a threaded rod 101 rotatably mounted on one side of the water tank 100. An interceptor plate 103 is slidably installed inside the water tank 100. Two connectors 105 are fixedly installed on the upper side of the interceptor plate 103. One connector 105 is threaded onto the outer surface of the threaded rod 101. A motor 102 is fixedly installed at one end of the threaded rod 101. A sealing strip 104 is fixedly installed on the outer surface of the interceptor plate 103 on one side of the water tank 100. The height of the interceptor plate 103 is slightly lower than the height of the water tank 100. An overflow channel is formed on the upper side of the interceptor plate 103. A slide rod 106 is fixedly installed on the other side of the water tank 100. Another connector 105 is slidably disposed on the outer surface of the slide rod 106. A water inlet 107 is provided at one end of the water tank 100, a water outlet 108 is provided at the other end of the water tank 100, a water outlet 2 109 is provided in the middle of the water tank 100, and a scale 110 is provided on one side of the water tank 100.

[0034] In this embodiment, during use, the motor 102 is started, and the threaded rod 101 is rotatably mounted on one side of the water tank 100. The motor 102 is connected to the threaded rod 101, thereby causing the motor 102 to drive the threaded rod 101 at the output end to rotate. An interceptor plate 103 is slidably disposed inside the water tank 100. A sealing strip 104 is installed on the outer surface of the interceptor plate 103. The sealing strip 104 is made of silicone and can fit the interceptor plate 103 against the water tank 100 to prevent water leakage. Two connectors 105 are fixedly installed on the upper side of the interceptor plate 103. One connector 105 is threaded onto the outer surface of the threaded rod 101. Therefore, the rotation of the threaded rod 101 can drive the interceptor plate 103 to slide inside the water tank 100. Another slide rod 106 is fixedly installed on the other side of the water tank 100. The other connector 105 is slidably disposed on the outer surface of the slide rod 106. Therefore, the stability of the interceptor plate 103 moving inside the water tank 100 can be improved. A scale 110 is provided on one side of the 00, which enables precise movement of the interceptor plate 103. By moving the interceptor plate 103 to the bottom of the water tank 100, the water entering through the inlet 107 will flow through the water tank 100 and be discharged from the outlet 108, thereby increasing the length of the water flow path, which is suitable for cooling narrow products. At this time, the outlet 2 109 is closed, and the interceptor plate 103 is moved to the middle position. The water entering through the inlet 107 will be intercepted by the interceptor plate 103. At this time, the outlet 2 109 is opened, and the water will be discharged through the outlet 2 109, thereby shortening the water flow path, which is suitable for cooling wide products. The height of the interceptor plate 103 is lower than the height of the water channel of the water tank 100. An overflow channel is formed on the upper side of the interceptor plate 103. The water flow blocked by the interceptor plate 103 will form high pressure on one side of the interceptor plate 103, which allows some water to enter the other side of the interceptor plate 103 through the overflow channel, thereby relieving the pressure on the interceptor plate 103.

[0035] Example 2, as Figure 4 The water control assembly shown also includes a telescopic rod 201, which is fixedly installed on one side of the outer surface of the water tank 100, and the drive end of the telescopic rod 201 is fixedly installed on one side of the connector 105.

[0036] In this embodiment, the telescopic rod 201 is fixedly installed on one side of the water tank 100. The driving end of the telescopic rod 201 is fixedly connected to the connector 105. Thus, the push of the telescopic rod 201 can drive the connector 105 to move along the water tank 100, thereby driving the interceptor plate 103 to slide in the water tank 100 through the connection of the connector 105.

[0037] Working principle: During use, when the motor 102 is started, the threaded rod 101, which is rotatably mounted on one side of the water tank 100, is connected to the motor 102, thus driving the threaded rod 101 at the output end to rotate. An interceptor plate 103 is slidably installed inside the water tank 100. A sealing strip 104, made of silicone, is installed on the outer surface of the interceptor plate 103. The sealing strip 104 ensures that the interceptor plate 103 fits snugly against the water tank 100, preventing water leakage. Two connectors 10 are fixedly installed on the upper side of the interceptor plate 103. 5. One of the connectors 105 is threaded onto the outer surface of the threaded rod 101. Therefore, the rotation of the threaded rod 101 can drive the interceptor plate 103 to slide within the water tank 100. Another slide rod 106 is fixedly installed on the other side of the water tank 100, and the other connector 105 is slidably disposed on the outer surface of the slide rod 106. This improves the stability of the interceptor plate 103's movement within the water tank 100. A scale 110 is provided on one side of the water tank 100, enabling precise movement of the interceptor plate 103. By moving the interceptor plate 103 to the bottom of the water tank 100... Water entering through inlet 107 flows through water tank 100 and exits through outlet 108, thus increasing the water flow path length and making it suitable for cooling narrow products. At this time, outlet 109 is closed, and interceptor plate 103 is moved to the middle position. Water entering through inlet 107 is intercepted by interceptor plate 103. Then, outlet 109 is opened, and water flows out through outlet 109, thus shortening the water flow path and making it suitable for cooling wide products. The height of interceptor plate 103 is lower than the height of the water channel in water tank 100. The upper side of interceptor plate 103... An overflow channel is formed, and the water flow blocked by the interceptor plate 103 will form a high pressure on one side of the interceptor plate 103, thereby allowing a portion of the water flow to enter the other side of the interceptor plate 103 through the overflow channel, thus relieving the pressure on the interceptor plate 103. The telescopic rod 201 is fixedly installed on one side of the water tank 100, and the driving end of the telescopic rod 201 is fixedly connected to the connector 105. Thus, the push of the telescopic rod 201 can drive the connector 105 to move along the water tank 100, thereby driving the interceptor plate 103 to slide within the water tank 100 through the connection of the connector 105.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
