Description

Technical Field

[0001] This utility model belongs to the technical field of anti-leakage devices, and particularly relates to an anti-leakage device for sealing the end face of a calender roller. Background Technology

[0002] The calender roll end face sealing anti-leakage device is a special sealing system used to prevent material leakage at both ends of the roll during the calendering process.

[0003] In the prior art, the sealing and leak prevention function is generally accomplished by using an annular baffle installed on the end face of the calender roll. However, since the position of the annular baffle cannot be adjusted, the roll can only be used for sealing and leak prevention operations of a fixed size, which reduces the applicability of the roll. Utility Model Content

[0004] The purpose of this utility model is to provide a sealing and leak-proof device for the end face of a calender roll to solve the problems mentioned in the background art, including:

[0005] A roller body that can be mounted on a calender, wherein two first grooves are formed on the surface of the roller body;

[0006] Two adjustment components are respectively disposed in the first tank. The adjustment components include a second plate that can be moved to change the position of the leakage.

[0007] Two extension components are respectively mounted on the second plate. The extension components include a third plate that is movable and elastic, thereby allowing the location of the leakage to be further changed.

[0008] Preferably, the surface of the roller body is further provided with two second grooves, which can accommodate part of the structure of the adjustment component.

[0009] Preferably, the adjustment component includes:

[0010] A threaded rod, which is rotatably mounted in the first groove;

[0011] A driving component that can drive the threaded rod to rotate;

[0012] The first plate is slidably installed in the first groove, and the first plate is threaded through and connected by a threaded rod. The second plate is fixed to the first plate.

[0013] Preferably, the driving component is a bolt head.

[0014] Preferably, the plug head is an internal hexagonal plug head.

[0015] Preferably, the plug head is disposed within the second groove.

[0016] Preferably, the extension component includes:

[0017] A housing is fixedly mounted on the opposite sides of two second plates, and a cavity is provided inside the housing.

[0018] An elastic element, which is installed inside the cavity;

[0019] A rod is disposed within a cavity and fixed to an elastic element. The rod penetrates a second plate, and a third plate is fixed to the rod.

[0020] Preferably, the elastic element includes a first magnet and a second magnet, which repel each other.

[0021] Preferably, the first magnet is fixedly installed in the cavity at a position away from the second plate, and the second magnet is slidably installed in the cavity at a position close to the second plate.

[0022] Preferably, the rod and the second magnet are fixed together.

[0023] This application uses a drive component to rotate a threaded rod, which in turn causes the first plate to slide within the first groove. Simultaneously, the first plate moves the second plate, thereby changing the leakage position of the second plate. This makes it suitable for sealing and leak-proof operations of different sizes, improving the applicability of the device. Attached Figure Description

Detailed Implementation

[0030] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0031] To address the issue of the inability to adjust the position of the annular baffle, this embodiment provides a sealing device to prevent material leakage at the end face of the calender roll, such as... Figure 1 As shown, it includes: a roller body 100, two adjusting components 200, and two extending components 300. (As shown...) Figure 3 As shown, the unknown sealing and leak-proof material is changed by moving the second plate 240 of the adjustment assembly 200, thereby improving the applicability of the device.

[0032] like Figure 1 As shown, the roller body 100 is a prior art technology that can be installed on a calender. The surface of the roller body 100 has two first grooves 110 (the location of the grooves is shown in the figure, and the shape is similar to a rectangle).

[0033] like Figure 2 As shown, the two adjustment components 200 are respectively disposed within the first groove 110, as... Figure 3 As shown, the adjustment component 200 includes a second plate 240 (annular), which can be moved to change the position of the material leakage. Specifically, the surface of the roller 100 is also provided with two second grooves 120 (circular), which can accommodate part of the structure of the adjustment component 200. The adjustment component 200 also includes a threaded rod 210, a driving member 220, and a first plate 230.

[0034] The threaded rod 210 is a prior art technology, which is rotatably mounted in the first groove 110 via a bearing. One end of the threaded rod 210 passes through the roller 100 and extends into the second groove 120. The driving component 220 can drive the threaded rod 210 to rotate. The driving component 220 is a bolt head (the bolt head is an internal hexagonal bolt head). The bolt head is fixed to the threaded rod 210. The bolt head is located in the second groove 120 (so that the bolt head cannot be easily touched by the outside, and the bolt head will not rotate due to accidental external contact, causing the position of the second plate 240 to change). The first plate 230 (rectangular) is slidably mounted in the first groove 110. The first plate 230 is penetrated and threadedly connected by the threaded rod 210. The second plate 240 is fixed to the first plate 230.

[0035] When it is necessary to adjust the position of the leaking material, the drive component 220 (bolt head) is rotated by using a wrench (Hex wrench). The drive component 220 drives the threaded rod 210 to rotate, and the threaded rod 210 drives the first plate 230 to slide in the first groove 110. Simultaneously, the first plate 230 drives the second plate 240 to move, thereby changing the position of the leaking material in the second plate 240. This is suitable for sealing and preventing leaking material of different sizes, improving the applicability of the device.

[0036] Because the adjustment range of the adjustment component 200 is limited, the available adjustment range is still insufficient for practical use. Further solutions, such as... Figure 1 As shown, the two extension components 300 are respectively mounted on the second plate 240, as... Figure 4 As shown, the extension assembly 300 includes a third plate 350 (annular, disposed on the adjacent surfaces of the two second plates 240, i.e., surfaces close to each other). The third plate 350 is movable and elastic (its elasticity allows it to remain tightly attached, maintaining a sealing and leak-proof effect), thereby allowing the leak location to be further changed. Specifically, the extension assembly 300 includes: a housing 310, an elastic element, and a rod 340.

[0037] The shell 310 (rectangular) is fixedly installed on the opposite sides (the sides away from each other) of the two second plates 240. The shell 310 has a cavity (rectangular) inside. The elastic element is elastic and is installed in the cavity. The rod 340 (cylindrical long rod) is set in the cavity and fixed to the elastic element. The rod 340 passes through the second plate 240. The third plate 350 is fixed to the rod 340.

[0038] During use, the third plate 350 provides a sealing and leak-proof function. At the same time, since the elastic element pushes the rod 340 and the third plate 350 in sequence to press against the leaking position, it can maintain a tight fit even when the third plate 350 is worn. Meanwhile, the housing 310 provides a certain stroke, which can increase the limited range of the adjustment component 200, further improving the adjustment effect of sealing and leak-proofing and the applicability of the device.

[0039] To ensure a longer service life for the elastic element, further solutions include, for example... Figure 4 As shown, the elastic element includes a first magnet 320 and a second magnet 330. The first magnet 320 and the second magnet 330 repel each other. The first magnet 320 is fixedly installed in the cavity at a position away from the second plate 240, and the second magnet 330 is slidably installed in the cavity at a position close to the second plate 240. The rod 340 and the second magnet 330 are fixed together. Preferably, the first magnet 320 and the second magnet 330 are permanent magnets, which provides stable elasticity and a longer service life, which is superior to springs.
