Abstract
Description
Technical Field
[0001] The utility model relates to a liquid splash-proof structure for a rubber roller port. Background Art
[0002] In the production process of printing plate materials, there are surface chemical treatment processes and water washing processes for aluminum plate bases. Regardless of the surface chemical treatment process or the water washing process, a process tank is required. Rollers are installed in the process tank to transport the aluminum plate base. In order to prevent acid and alkali corrosion, the surface of the roller is covered with a rubber layer, so it is called a rubber roller. The two ends of the rubber roller are supported on the brackets on both sides of the process tank. For this reason, the tank walls on both sides of the process tank must be opened, and the two openings on both sides often have liquid splashing during the production process, whether it is acid, alkali or water. Moreover, the rubber roller has the function of rotating during production and the rubber roller needs to be raised during non-production, which determines that the blocking of the opening must be a dynamic blocking in order to achieve both the purpose and the functional needs, which is exactly what this practical technology considers. Utility Model Content
[0003] The utility model provides a liquid splash-proof structure for a rubber roller port, which can effectively solve the above-mentioned problem.
[0004] The utility model is achieved in this way:
[0005] A liquid splash-proof structure for a rubber roller port, comprising:
[0006] The rubber roller comprises a rubber roller end shaft, the rubber roller end shaft is arranged at both ends of the rubber roller and is connected to the rubber roller;
[0007] The slot wall gate is used to reduce the gap between the end shaft of the rubber roller and the slot wall opening to prevent liquid from splashing out;
[0008] A slide rail is symmetrically arranged on the inner side surface of the slot wall gate;
[0009] The movable rubber plate is slidably connected with the slide rail and forms dynamic contact with the end shaft of the rubber roller.
[0010] As a further improvement, the movable rubber plate includes a rubber sheet and a PP plate, and is placed above the end shaft of the rubber roller.
[0011] As a further improvement, a buffer chamber is formed between the rubber roller end shaft and the groove wall gate.
[0012] As a further improvement, there is a distance R between the end shaft of the rubber roller and the buffer cavity, wherein R is greater than or equal to 10 cm or less than or equal to 15 cm.
[0013] As a further improvement, the arc end of the rubber sheet protrudes from the arc end of the hard plate and has a length D, wherein D is greater than or equal to 5 mm or less than or equal to 10 mm.
[0014] As a further improvement, groove wall side plates are symmetrically connected to both sides of the groove wall gate plate.
[0015] As a further improvement, an inclined portion is formed at the bottom of the groove wall gate from the inside to the outside, which abuts against the inclined surface formed by the groove wall opening to prevent liquid from splashing out.
[0016] As a further improvement, a fixed rubber sheet is fixedly provided on the inner side surface of the slot wall gate.
[0017] The beneficial effects of the utility model are:
[0018] (1) The utility model adopts a dynamic blocking concept to minimize the gap between the slot wall gate and the rubber roller end shaft. At the same time, a movable rubber plate composed of a PP plate and a rubber sheet is used. Since the movable rubber plate falls on the rubber roller end shaft along the slide rail by its own gravity, the semicircular arc of the movable rubber plate just forms a close contact with the upper half of the rubber roller end shaft, and the lower half of the rubber roller end shaft forms a close contact with the semicircular arc of the fixed rubber sheet installed on the slot wall lower gate, thereby achieving a dynamic blocking of the entire annular gap between the slot wall gate and the rubber roller end shaft to prevent liquid from splashing out of the annular gap. Furthermore, when the rubber roller needs to be operated to rise, the movable rubber plate rises along the track as the rubber roller is lifted, and falls as the rubber roller is lowered; when the rubber roller needs to be replaced, the splash-proof movable rubber plate can be taken out so that the rubber roller can be completely lifted and replaced.
[0019] (2) The movable rubber plate and the fixed rubber plate provided in the utility model are combined up and down to reduce the annular gap between the slot wall gate and the end shaft of the rubber roller, thereby preventing liquid from splashing out. At the same time, combined with the setting of the buffer chamber and the inclined surface, the acid and alkali liquid or water washing in the surface treatment and water washing process of the printing plate material will not splash out or flow out, so as to injure the operator, thereby improving the safety of production.

[0028] Reference Figure 1-3 As shown, a liquid splash-proof structure for a rubber roller port includes:
[0029] The rubber roller 1 comprises a rubber roller end shaft 2, which is arranged at both ends of the rubber roller 1 and is connected to the rubber roller 1. The groove wall gate plate 3 is symmetrically connected to the groove wall side plates 8 on both sides.
[0030] The groove wall gate plate 3 is used to reduce the gap between the rubber roller end shaft 2 and the groove wall opening 11 to prevent liquid from splashing out.
[0031] Furthermore, the groove wall gate plate 3 is provided with upper, middle and lower gate plates (not shown in the figure), and the upper, middle and lower gate plates and one end of the rubber roller end shaft 2 form a sealing ring.
[0032] The slide rail 5 is symmetrically arranged on the inner side surface of the slot wall gate plate 3.
[0033] The movable rubber plate 4 is slidably connected to the slide rail 5.
[0034] The movable rubber plate 4 includes a rubber sheet 41 and a PP plate 42, and is placed above the rubber roller end shaft 2. The arc end of the rubber sheet 41 protrudes from the arc end of the PP plate 42, and has a length D, wherein D is greater than or equal to 5 mm or less than or equal to 10 mm; in one embodiment, preferably, the length D is about 5 mm. The advantage of this arrangement is that it can be in dynamic contact with the rubber roller end shaft 2 to act as a seal, and the rubber sheet 41 is softer than the rubber roller end shaft 2, and is not easy to damage the surface of the rubber roller end shaft 2 during dynamic contact. (The rubber sheet 41 can be replaced at any time and has a low value; while the rubber roller 1 has a high value, and if the rubber roller end shaft 2 is damaged, it is equivalent to the value of the rubber roller 1 being damaged).
[0035] Furthermore, the rubber sheet 41 is elastic, while the PP plate 42 can provide rigidity. The combination of the two is more convenient to use. Moreover, the rubber sheet 41 can absorb the impact caused by the vibration or pressure fluctuation of the rubber roller end shaft 2, and reduce the damage to the PP plate 42 and the rubber roller end shaft 2. At the same time, the rubber sheet 41 is durable and can better resist long-term wear and tear. Finally, the rubber sheet 41 can be used as a part that is easy to grasp and operate, which is convenient for the installation and disassembly of the movable rubber plate 4.
[0036] A fixed rubber sheet 9 is fixedly arranged on the inner side surface of the groove wall gate plate 3. The fixed rubber sheet 9 is made of the same material as the rubber sheet 41. The fixed rubber sheet 9 and the movable rubber plate 4 form an upper and lower combination to form a circle of sealing on the rubber roller end shaft 2. While sealing, the size of the groove wall opening 11 can be reduced to prevent liquid from splashing to the outside.
[0037] It should be noted that if only one PP plate 42 is provided, dynamic friction may occur between the PP plate and the rubber roller end shaft 2. When the rubber roller end shaft 2 rotates, the PP plate 42 will wear the surface of the rubber roller end shaft 2, eventually causing the rubber roller to be damaged and replaced, which increases certain costs. On the other hand, if only one rubber sheet 41 is provided, the rigidity of the movable plate 4 is insufficient and it is easy to deform, and it cannot play the function of a movable plate with dynamic contact.
[0038] Furthermore, in this case, if the rubber roller end shaft 2, the movable rubber plate 4 and the groove wall gate plate 3 are fixedly blocked, the rubber roller end shaft 2 cannot be lifted, that is, the rubber roller 1 cannot be replaced. In other words, to replace the rubber roller 1, the anti-splashing fixed block must be removed first each time, and then the rubber roller 1 is replaced. After replacement, the anti-splashing fixed block must be reinstalled, which is obviously unreasonable and unwise. Therefore, as a preferred embodiment, the rubber roller end shaft 2, the movable rubber plate 4 and the groove wall gate plate 3 are set as dynamic blocks.
[0039] A buffer chamber 6 is formed between the rubber roller end shaft 2 and the groove wall gate plate 3; there is a distance R between the rubber roller end shaft 2 and the buffer chamber 6, wherein R is greater than or equal to 10 cm or less than or equal to 15 cm. In one embodiment, preferably, R is about 13 cm. At the same time, the distance R is equivalent to the inner diameter of the rubber roller end shaft 2 to prevent the liquid from suddenly expanding and splashing when flowing out of the rubber roller end shaft 2.
[0040] Furthermore, the spacing R can also be larger than the inner diameter of the rubber roller end shaft 2 to provide enough space to slow down the flow rate of the liquid and absorb pressure fluctuations. It can be set according to actual needs, and this case is not limited in this regard.
[0041] Furthermore, an inclined portion 10 is formed from the inside to the outside at the bottom of the slot wall gate 3, which abuts against the inclined surface formed by the slot wall opening 11 to prevent liquid from splashing out. The setting of the inclined surface can ensure that when the liquid flows to the bottom of the slot wall opening 11, the liquid will not splash, and the liquid will flow back into the device along the inclined surface.
[0042] Furthermore, when the liquid impacts the inclined surface, the inclined surface can disperse the impact force of the liquid and reduce the concentrated impact on a specific point. At the same time, the inclined surface can change the flow direction of the liquid, thereby reducing the possibility of the liquid splashing directly forward. Moreover, the liquid will slow down in the process of rising along the inclined surface, increasing the contact time and contact area between the liquid and the gate, which helps to reduce splashing. Finally, the inclined surface uses gravity to help the liquid flow along the gate surface instead of splashing vertically upward or toward the observer / equipment.
[0043] It should be noted that the setting of the movable rubber plate 4 in this case can reduce the arc gap between the groove wall gate plate 3 and the rubber roller end shaft 2, so as to avoid liquid splashing. At the same time, combined with the setting of the buffer chamber 6 and the inclined surface, the acid and alkali liquid or aqueous solution in the surface treatment and washing process of the printing plate base surface will not splash to the outside or injure the operator, thereby improving the safety of production.
[0044] Furthermore, the tank wall gate plate 3 is made of a material that is resistant to chemical corrosion, wear and easy to clean. The specific material will not be described in detail here, and can be designed according to actual needs.
[0045] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
