Description

Technical Field

[0001] This utility model relates to the field of long roller technology, and in particular to a structure that can reduce the heating deformation of long rollers. Background Technology

[0002] Long rollers are cylindrical, rotatable objects in machinery. They are often driven by a power source to move other materials forward or to generate pressure to process materials. They are commonly used for processing fabrics. During the processing, heating devices are often installed to improve the processing effect, but the long rollers may deform during the heating process.

[0003] Existing anti-deformation structures for long rollers rely on support frames for deformation prevention. However, when heating the long rollers, the rollers stretch and elongate under the influence of heat, causing them to deform due to mutual compression between the rollers and the mounting base. Furthermore, some support frames are designed as a single piece, making it difficult for operators to adjust their position. This results in inconvenience and low flexibility when the heated long rollers are in operation.

[0004] Therefore, in response to the problem that the long roller stretches and expands during heating, causing it to deform due to mutual compression between the long roller and the mounting base, and that the existing support frame is an integrated design, making the heated long roller inconvenient and less flexible during operation, this utility model addresses this issue. Under the action of the second spring, the moving block drives the connecting block to move, which in turn drives the second mounting base to move synchronously, preventing the second mounting base from being squeezed and deformed by the heating roller. At the same time, by rotating the rocker arm, the threaded rod rotates, causing the threaded connecting block to move along the thread direction, thereby moving the support component and facilitating the subsequent operation of the heating roller. Utility Model Content

[0007] Preferably, the support assembly includes a mounting plate, a telescopic rod, a connecting plate, a first spring, a support rod, a support frame, a clamping plate, bolts, and threaded holes. The telescopic rod is installed at both ends of the mounting plate, and the connecting plate is installed at the upper end of the telescopic rod. The first spring is sleeved on the surface of the telescopic rod. One end of the first spring is fixedly connected to the connecting plate, and the other end of the first spring is fixedly connected to the mounting plate.

[0008] Preferably, a support rod is fixedly installed in the connecting plate, a support frame is installed at the upper end of the support rod, a clamping plate is installed at the rear end of the support rod, a bolt is installed in the clamping plate, and a threaded hole is opened on the surface of the rear end of the mounting plate, and the bolt is connected to the threaded hole.

[0009] Preferably, the front end of the fixing plate is equipped with guide rails at the left and right ends of the threaded rod, the front end of the guide rail is equipped with a first baffle, the first baffle is rotatably connected to the threaded rod, the surface of the guide rail is slidably connected with a guide block, and the guide block is fixedly connected to the rocker arm.

[0010] Preferably, a side plate is installed on the right end of the base, and a slide rail is installed on the left end of the side plate. There are two slide rails, and a slider is slidably connected to the surface of the slide rail. A connecting block is fixedly installed between the two sliders, and a second baffle is installed on the left end of the slider.

[0011] Preferably, the surface of the base is provided with a mounting groove, and a sliding rod is installed inside the mounting groove.

[0013] The beneficial effects of this utility model are:

[0014] When the device is working, the heating roller stretches axially after heating, which drives the second mounting base to move. This causes the connecting block connected to the second mounting base to slide synchronously along the slide rail with the slider, thereby moving the second mounting base and avoiding deformation caused by the heating roller pressing against the second mounting base. Furthermore, under the action of the second spring, the moving block slides along the slide bar, thereby achieving the reset operation of the second mounting base and increasing the flexibility of the device.

[0015] This device supports the heating roller via a support assembly. The support frame fits snugly against the heating roller to prevent deformation. Operators can rotate a rocker arm to move the threaded block along the thread direction and simultaneously move the guide block along the guide rail, thus moving the support assembly. The connection between the clamping plate and the mounting plate is achieved by rotating bolts, facilitating easy disassembly and reassembly of the support assembly and heating roller, increasing the device's convenience.

[0023] 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.

[0024] Please see Figures 1-6 This utility model provides a technical solution: a structure that can reduce the deformation of a long roller under heating, including a base 1; a first mounting seat 2 is installed on the left side of the upper end of the base 1, a heating roller 3 is rotatably connected to the right end of the first mounting seat 2, a second mounting seat 4 is rotatably connected to the right end of the heating roller 3, a fixing plate 5 is installed on the rear side of the upper end of the base 1, a threaded rod 6 is rotatably connected in the fixing plate 5, a rocker arm 61 is installed at the rear end of the threaded rod 6, a threaded block 62 is threadedly connected to the surface of the rocker arm 61, a positioning plate 7 is installed at the upper end of the threaded block 62, and a support assembly is provided at the upper end of the positioning plate 7, with four support assemblies.

[0025] The support assembly includes a mounting plate 8, a telescopic rod 81, a connecting plate 82, a first spring 83, a support rod 84, a support frame 85, a clamping plate 86, bolts 87, and threaded holes 88. The telescopic rod 81 is installed at both the front and rear ends of the mounting plate 8, and the connecting plate 82 is installed at the upper end of the telescopic rod 81. The first spring 83 is sleeved on the surface of the telescopic rod 81. One end of the first spring 83 is fixedly connected to the connecting plate 82, and the other end of the first spring 83 is fixedly connected to the mounting plate 8. By setting up the support assembly, the heating roller 3 can be supported, and the deformation of the heating roller 3 during the heating process can be avoided.

[0026] A support rod 84 is fixedly installed in the connecting plate 82. A support frame 85 is installed at the upper end of the support rod 84. A clamping plate 86 is installed at the rear end of the support rod 84. A bolt 87 is installed in the clamping plate 86. A threaded hole 88 is opened on the surface of the rear end of the mounting plate 8. The bolt 87 is connected to the threaded hole 88. By opening the threaded hole 88, the operator can rotate the bolt 87 to connect the clamping plate 86 to the mounting plate 8 to complete the retraction operation of the support assembly, which makes it easy for the operator to separate the support assembly from the heating roller 3.

[0027] Guide rails 51 are installed at the front end of the fixed plate 5 at the left and right ends of the threaded rod 6. A first baffle 52 is installed at the front end of the guide rail 51. The first baffle 52 is rotatably connected to the threaded rod 6. A guide block 53 is slidably connected to the surface of the guide rail 51. The guide block 53 is fixedly connected to the rocker arm 61. By setting the guide rail 51, the guide block 53 slides along the direction of the guide rail 51, so as to control the guide block 53 to move synchronously with the threaded block 62 along the thread direction, thereby increasing the stability of the device.

[0028] A side plate 9 is installed on the right end of the base 1, and a slide rail 91 is installed on the left end of the side plate 9. There are two slide rails 91, and a slider 92 is slidably connected to the surface of the slide rail 91. A connecting block 93 is fixedly installed between the two sliders 92. A second baffle 94 is installed on the left end of the slider 92. By installing the slide rail 91 on the surface of the base 1, the slider 92 slides on the slide rail 91 to control the second mounting seat 4 to move synchronously with the connecting block 93.

[0029] The surface of the base 1 is provided with a mounting groove 10, and a slide rod 101 is installed inside the mounting groove 10. There are two slide rods 101. A moving block 102 is slidably connected to the surface of the slide rod 101. The upper end of the moving block 102 is fixedly connected to the connecting block 93. The upper end of the connecting block 93 is fixedly connected to the second mounting seat 4. By providing a mounting groove 10 on the surface of the base 1, the moving block 102 slides along the direction of the slide rod 101 in the mounting groove 10, and moves synchronously with the connecting block 93.

[0030] A second spring 103 is sleeved on the surface of the slide bar 101. One end of the second spring 103 is fixedly connected to the base 1, and the other end of the second spring 103 is fixedly connected to the moving block 102. During the movement of the moving block 102, the second spring 103 is stretched. Under the action of the second spring 103, the moving block 102 is reset, which increases the elasticity of the device and avoids the deformation problem caused by the heating roller 3 pressing against the second mounting seat 4 after heating.

[0031] Working principle: According to Figure 2 , Figure 5 and Figure 6When heating roller 3 is heated, it stretches axially, causing it to press against second mounting seat 4. This causes second mounting seat 4 to move connecting block 93, which in turn moves slider 92 along slide rail 91. Simultaneously, connecting block 93 moves moving block 102 in mounting groove 10 along slide rod 101 to complete the movement of second mounting seat 4. This avoids deformation of heating roller 3 caused by mutual compression between heating roller 3 and second mounting seat 4. Furthermore, under the action of second spring 103, second mounting seat 4 is automatically reset, preventing deformation caused by prolonged stretching of heating roller 3.

[0032] according to Figure 1 , Figure 3 and Figure 4 The device supports the heating roller 3 via a support frame 85, preventing deformation of the heating roller 3. After the heating roller 3 has finished heating, the operator can rotate the rocker arm 61 to rotate the threaded rod 6. During the rotation of the threaded rod 6, the threaded block 62 connected to the thread moves along the thread direction, and simultaneously drives the guide block 53 to slide along the guide rail 51. Before rotating the rocker arm 61, the connecting plate 82 is pressed to make the clamping plate 86 fit with the mounting plate 8. Then, the bolt 87 is rotated to connect the clamping plate 86 with the mounting plate 8. This makes it easier for the operator to move the support assembly synchronously with the positioning plate 7, facilitating subsequent operation of the heating roller 3 and increasing the convenience of the device.

[0033] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
