Description

Technical field:

[0001] The present application relates to the technical field of calenders, and in particular to a trimming device for a rubber calender. Background technology:

[0002] The calender can be used to press and extend materials such as rubber into films. During the calendering process, due to the soft texture of the rubber material, the rubber material will extend outward after being squeezed by the calender roller, making the edge of the rubber material present an irregular shape. Therefore, a rubber edge cutting device is required to trim the edge of the rubber material.

[0003] The Chinese national invention patent with patent application number 201210187804.8 is an automatic cutter for a calender, comprising a blade, a knife rod, a cylinder, a linear bearing, a bracket, an infrared detection device, an electric push rod, a hand wheel and a forward and reverse screw rod. The blade is mounted on the front end of the knife rod, the cylinder is mounted on the knife rod, the linear bearing and the infrared detection device are respectively mounted on the bracket, the electric push rod is connected to one end of the forward and reverse screw rod through a connecting plate, and the hand wheel is mounted on the other end of the forward and reverse screw rod.

[0004] The technical solution adopted by this patent solves the problem of positioning the cutter, but it can only cut the edge of the rubber product into a vertical plane. Rubber products with vertical edges can only be laid by directly aligning the edges. In this way, the contact parts of adjacent rubber products are limited to their respective edge vertical planes, resulting in a smaller contact area and weak bonding between the rubber products.

[0026] In order to make the purpose, technical scheme and advantages of the implementation of the utility model clearer, the utility model will now be further described in detail with reference to the accompanying drawings and the following examples so that the public can better understand the implementation method of the utility model. The specific implementation scheme of the utility model is as follows:

[0027] A rubber calender trimming device comprises a frame 1, on which two parallel calendering rollers 2 are arranged in a rotating structure, on which a fixed shaft 3 arranged parallel to the calendering roller 2 is arranged outside the calendering roller 2, the fixed shaft 3 is connected to the frame 1 in a fixed structure, and a sliding base 4 is sleeved outside the fixed shaft 3 in a rotating structure, so that the sliding base 4 can rotate along the axis of the fixed shaft 3, thereby adjusting the direction of a telescopic knife, and the sliding base 4 can move axially along the fixed shaft 3, so that the telescopic knife can cut the edges of rubber products of different widths; the telescopic knife is arranged on the sliding base 4 in an articulated structure, and an angle adjustment device for measuring the angle between the telescopic knife and the fixed shaft 3 is arranged on the upper end surface of the sliding base 4 outside the telescopic knife, the angle adjustment device is connected to the sliding base 4 in a fixed structure, and a locking mechanism is arranged on the angle adjustment device and the telescopic knife; the arrangement of the angle adjustment device, the telescopic knife, and the sliding base 4 can cut the edge of the rubber product at different angles, and is suitable for rubber products of different thicknesses and different widths, so that the edges of the rubber products are more closely fitted when paving, and the bonding force is increased.

[0028] Specifically, the upper end surface of the sliding base 4 is provided with a hinge seat 5 in a fixed structure manner, and the hinge seat 5 is provided with a pin shaft 6 connected to the telescopic knife; the telescopic knife can be swung left and right along the axial direction of the fixed shaft 3 with the pin shaft 6 as the center to adjust the inclination angle of the telescopic knife relative to the fixed shaft 3, thereby adjusting the angle of the telescopic knife cutting the edge of the rubber product.

[0029] It should be noted that: the telescopic knife includes a handle 8 and a knife body 7 arranged inside the handle 8, the knife body 7 can be telescopically moved relative to the handle 8 to ensure that the end of the knife body 7 is in contact with the calendering roller 2 to cut the rubber product; a strip slide groove 9 is provided on the side of the handle 8, and a first bolt 10 is arranged in the strip slide groove 9 in a sliding structure manner, the first bolt 10 is connected to the knife body 7 by a threaded engagement manner, and the first bolt 10 can fix the knife body 7 when the knife body 7 moves to a required height to prevent the knife body 7 from shifting during the cutting process, and the first bolt 10 limits the moving distance of the knife body 7 to the length of the strip slide groove 9 to prevent the knife body 7 from falling off from the cavity of the handle 8 due to excessive movement; a gasket 11 is arranged between the first bolt 10 and the handle 8; the gasket 11 can increase the contact area between the first bolt 10 and the handle 8, thereby increasing the friction between the first bolt 10 and the handle 8, preventing the first bolt 10 from moving relative to the handle 8, and avoiding the wear caused by the long-term contact between the surface of the first bolt 10 and the surface of the handle 8, thereby increasing the service life of the parts.

[0030] It should be explained that the angle adjustment device includes a protractor 12 and a pointer 13, the pointer 13 is arranged on the protractor 12 in a rotating structure, and the protractor 12 is connected to the sliding base 4 in a fixed structure; one end of the pin 6 passes through the protractor 12 and is connected to the pointer 13, and the center axis of the pin 6 is concentrically arranged with the protractor 12, so that the pointer 13 and the telescopic knife can rotate synchronously, and both use the pin 6 as the rotation center, thereby ensuring that the rotation amplitude of the pointer 13 and the telescopic knife is the same.

[0031] Furthermore, the locking mechanism includes a second bolt 14 and an arc groove 15 provided on the protractor 12. The setting of the arc groove 15 enables the second bolt 14 to rotate synchronously with the pointer 13 and the telescopic knife along the arc groove 15; the second bolt 14 passes through the pointer 13 and the arc groove 15 and is connected to the knife handle 8 by threaded engagement. The second bolt 14 connects the pointer 13 and the telescopic knife on the same plane, so that the pointer 13 is in a state where it can rotate synchronously with the telescopic knife, so that the angle on the protractor 12 pointed by the pointer 13 is the angle between the telescopic knife and the fixed shaft 3, and then the angle between the telescopic knife and the calendering roller 2 is determined, and after adjusting the angle between the telescopic knife and the calendering roller 2, the second bolt 14 can be tightened to fully engage with the second bolt 14 hole, thereby fixing the inclination angle of the telescopic knife.

[0032] The working principle and working process of the utility model are as follows:

[0033] When in use, first slide the sliding base 4 to move the sliding base 4 to the position where the rubber product needs to be cut, then rotate the sliding base 4 to make the telescopic knife face the direction of the rubber product between the calendering rollers 2, then pass the second bolt 14 through the pointer 13 and engage with the knife handle 8 through a thread for a short distance, so that the pointer 13 and the telescopic knife can rotate synchronously, and then rotate the telescopic knife, the telescopic knife drives the pointer 13 to rotate around the pin 6 as the rotation center through the first bolt 10, after the pointer 13 rotates to point to the required angle, tighten the second bolt 14 to make the second bolt 14 fully engage with the knife handle 8, fix the inclination angle of the telescopic knife, and then slide the knife body 7 along the cavity in the knife handle 8 to adjust the height. After adjusting to the required height, place the gasket 11 on the first bolt 10, then engage the first bolt 10 with the knife body 7, fix the knife body 7 and the knife handle 8, at this time, the end of the knife body 7 contacts the calendering roller 2, and then when the rubber product passes through the calendering roller 2, the knife body 7 can cut the rubber product.
