Description

Technical Field

[0001] The utility model relates to the technical field of calendering equipment, in particular to a calender with a fine-tuning mechanism. Background Art

[0002] A calender is a machine composed of two or more rollers arranged in a certain form. At a certain temperature, it presses and extends rubber or plastic into a film with a certain thickness and surface shape, and can apply rubber to fiber cord fabric or steel cord fabric.

[0003] In the existing calender during the pressing process, the size between the two pressing rollers is relatively fixed. When processing materials with different thicknesses, sizes or dimensions, multiple presses are required or processing is impossible, so the applicability is poor.

[0004] The existing patent (Publication No.: CN206357525U) discloses a calender with a fine-tuning mechanism. A servo motor drives a small bevel gear to move, the small bevel gear drives a large bevel gear to move, the large bevel gear drives a nut to rotate, the nut pushes a lead screw to move forward and backward, the lead screw drives a push-pull block to move forward and backward. While the push-pull block moves forward and backward, the inclined surface where the push-pull block contacts the fine-tuning block has a relative displacement, so that the fine-tuning block is finely adjusted up and down to achieve the purpose of finely adjusting the lower pressing roller.

[0005] In view of the above problems, although the solution given by the existing patent can adjust the fine-tuning block through the cooperation of components such as the lead screw to drive the lower pressing roller to adjust its position, in the specific use process, the conventional lower pressing roller often lacks a corresponding driving structure when adjusting its position, resulting in possible insufficient power during pressing molding, which may lead to the situation of multiple presses for pressing the material, resulting in low efficiency or deformation. Summary of the Invention

[0006] The purpose of the utility model is to provide a calender with a fine-tuning mechanism, which can always make the two pressing rollers have rotational power when adjusting the distance of the pressing rollers, avoid insufficient power during pressing molding, and avoid deformation or the trouble of secondary pressing when pressing the material, which affects the processing quality and efficiency, so as to solve the problems put forward in the above background art.

On both sides of the top end of the bottom plate, support frames are fixed, and a top plate is connected above the support frames. On one side of the outer wall of the support frame, a bearing block is slidably connected, and a mounting plate is fixed below the bearing block on the outer wall of the support frame.

A first transmission member is arranged on the outer wall of the driving sleeve, and a limiting hole is opened at the top end of the driving sleeve. A sliding rod passes through the inside of the limiting hole. One end of the sliding rod passing into the bearing block is fixed with a connecting sleeve, and a second transmission member is arranged on the outer wall of the connecting sleeve. Pressing rollers are rotatably connected to the opposite outer walls of the two support frames.

[0009] Preferably, the sliding rod forms a rotating structure with the bearing block through the connecting sleeve, and the bearing block forms a rotating structure with the support frame.

[0010] Preferably, the sliding rod forms a sliding structure with the driving sleeve, and the external dimension of the sliding rod matches the external dimension of the limiting hole.

[0011] Preferably, a sliding groove is opened inside the support frame, and a sliding block is slidably connected inside the other support frame.

[0012] Preferably, a limiting mechanism is arranged on the outer wall of the bearing block. The limiting mechanism includes a rotating motor, which is embedded on the outer wall of the bearing block. The power output end of the rotating motor is connected with a bidirectional threaded rod, and a limiting block is slidably connected to the outer wall of the bidirectional threaded rod.

[0013] Preferably, the limiting mechanism further includes a limiting rod. The limiting rod passes through the bottom end of the limiting block, and a limiting plate is fixed at one end of the limiting rod located on the limiting block.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0026] The present invention provides a technical solution:

[0027] Please refer to Figures 1 to 3, A calender with a fine-tuning mechanism, including a bottom plate 1. On both sides of the top end of the bottom plate 1, support frames 2 are fixed. Above the support frames 2, a top plate 3 is connected. On one side of the outer wall of the support frame 2, a bearing block 4 is slidably connected. Below the bearing block 4 on the outer wall of the support frame 2, a mounting plate 5 is fixed. Below the mounting plate 5, a driving mechanism 6 is arranged; the driving mechanism 6 includes a driving motor 601, the driving motor 601 is embedded at the bottom end of the mounting plate 5, the power output end of the driving motor 601 is connected with a driving sleeve 602, a first transmission member 603 is arranged on the outer wall of the driving sleeve 602, a limiting hole 604 is opened at the top end of the driving sleeve 602, a sliding rod 605 passes through the inside of the limiting hole 604, one end of the sliding rod 605 passing through into the bearing block 4 is fixed with a connecting sleeve 606, a second transmission member 607 is arranged on the outer wall of the connecting sleeve 606, a pressing roller 608 is rotatably connected to the opposite outer walls of the two support frames 2, a rotating structure is formed between the sliding rod 605 and the bearing block 4 through the connecting sleeve 606, a rotating structure is formed between the bearing block 4 and the support frame 2, a sliding structure is formed between the sliding rod 605 and the driving sleeve 602, the outer dimension of the sliding rod 605 coincides with the outer dimension of the limiting hole 604, a chute 8 is opened inside the support frame 2, and a slider 7 is slidably connected inside the other support frame 2.

[0028] By adopting the above technical solution, the support frame 2 fixed by the bottom plate 1 fixes the top plate 3 to form a frame. With the cooperation of the hydraulic cylinder embedded in the top plate 3, the bearing block 4 drives the upper pressing roller 608 to move downward along the chute 8 to press the lower pressing roller 608 to adjust the position according to the material. The driving motor 601 embedded in the mounting plate 5 works to drive the driving sleeve 602, and then limits the sliding rod 605 through the limiting hole 604, which is convenient for driving the connecting sleeve 606 to rotate. It can drive the corresponding pressing roller 608 to rotate through the first transmission member 603 and the second transmission member 607. At the same time, as the sliding rod 605 slides along the driving sleeve 602, the driving sleeve 602 and the connecting sleeve 606 can adjust the position according to the pressing roller 608, and provide rotational power for the two pressing rollers 608 to avoid insufficient power affecting the pressing force. The slider 7 at the other end of the support frame 2 is embedded with a bearing to make the upper pressing roller 608 slide stably.

[0029] Specifically, such as Figure 1 , Figure 2 and Figure 4As shown in the figure, a limiting mechanism 9 is provided on the outer wall of the bearing block 4. The limiting mechanism 9 includes a rotating motor 901, which is embedded in the outer wall of the bearing block 4. The power output end of the rotating motor 901 is connected with a bidirectional threaded rod 902. A limiting block 903 is slidably connected to the outer wall of the bidirectional threaded rod 902. The limiting mechanism 9 further includes a limiting rod 904. The limiting rod 904 passes through the bottom end of the limiting block 903. A limiting plate 906 is fixed at one end of the limiting rod 904 located in the limiting block 903. A connecting plate 907 is fixed at the bottom end of the limiting rod 904. A limiting groove 905 is opened at the position corresponding to the connecting plate 907 at the top end of the bottom plate 1. The bidirectional threaded rod 902 is threadedly connected with the limiting block 903, and a sliding structure is formed between the limiting block 903 and the bidirectional threaded rod 902.

[0030] By adopting the above technical solution, the rotating motor 901 drives the bidirectional threaded rod 902, so that the two limiting blocks 903 are limited according to the material to avoid deviation during the pressing process. Supported by the limiting rod 904, the limiting block 903 remains stable when the driving mechanism 6 is adjusted and is prevented from rotating with the bidirectional threaded rod 902. The limiting plate 906 prevents the limiting rod 904 from detaching from the limiting block 903. At the same time, the limiting rod 904 passes through the connecting plate 907 along the limiting groove 905, making the sliding of the limiting block 903 stable.

[0031] Working principle: The bottom plate 1, the support frame 2 and the top plate 3 form the frame of the calender. The bearing block 4 and the slider 7 are pushed along the chute 8 by a suitable hydraulic cylinder, so that the distance between the two pressing rollers 608 can be adjusted. When adjusting the distance, the bearing block 4 drives the connecting sleeve 606, so that the sliding rod 605 penetrates into the limiting hole 604 and is automatically adjusted following the position of the pressing roller 608. At the same time, the driving motor 601 embedded in the mounting plate 5 is started to drive the driving sleeve 602, and the connecting sleeve 606 is driven to rotate through the sliding rod 605, so that the first transmission member 603 and the second transmission member 607 drive the corresponding pressing rollers 608 to rotate. The transmission member can be driven by two bevel gears or worm and worm wheel. At the same time, the meshing textures of the two transmission members are opposite, so that the material can be pressed and conveyed. After the position is adjusted, the rotating motor 901 drives the bidirectional threaded rod 902, so that the two limiting blocks 903 slide relatively or away from each other to limit the conveyed material to avoid deviation. When the limiting block 903 slides, the limiting rod 904 slides along the limiting groove 905 to improve stability. The limiting rod 904 penetrates into the limiting block 903 and is prevented from detaching by the limiting plate 906, so that the height is automatically adjusted following the adjustment of the driving mechanism 6, and the connecting plate 907 slides stably along the limiting groove 905.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
