Technical Field

[0001] The utility model relates to the technical field of production and manufacturing, in particular to a rubber sheet pressing mechanism. Background Art

[0002] In the production process of some silicone rubber products, silicone rubber strip raw materials are usually used. The strip raw materials are usually made by extruding the hot-melt rubber into sheets and then cutting them.

[0003] Some existing rubber sheeting mechanisms typically use two squeeze rollers to extrude the rubber. Sliders are typically installed at both ends of one of the squeeze rollers, and rails are installed on the corresponding inner walls of the device housing to allow the slides to slide, allowing the gap between the two squeeze rollers to be adjusted. However, this structure, where the slide rails are directly installed on the inner walls of the device housing, compresses the installation space for the squeeze rollers, shortening the length of the squeeze rollers and reducing the extrusion width, which can easily lead to reduced production efficiency. Utility Model Content

[0004] In view of this, the utility model provides a rubber sheeting mechanism, which is used to solve the problem that the slide rail setting structure of the rubber sheeting mechanism in the prior art is unreasonable, which will compress the installation space of the extrusion roller, shorten the length of the extrusion roller, reduce the extrusion area, and easily lead to reduced production efficiency.

[0008] The thin adjustment mechanism also includes an adjusting screw, which is arranged in the side wall of the mounting frame and whose axis is perpendicular to the driven pressure roller. The adjusting screw is connected to the thin slider and is used to adjust the front and rear position of the thin slider in the sliding window, thereby driving the driven pressure roller to approach or move away from the active pressure roller.

[0009] Preferably, the inner end of the adjusting screw abuts against one end of the thin slider, and the other end of the thin slider is provided with an elastic member, and the outer end of the elastic member abuts against the side of the sliding window. When the adjusting screw is pushed inward, the slider compresses and contracts the elastic member, and when the adjusting screw retracts outward, the elastic member pushes the thin slider back outward.

[0010] Preferably, a guide well in the same direction as the adjusting screw is provided in the slider, and the elastic member includes a spring and a top block, the inner end of the spring is connected to the inner wall of the guide well, and the outer end of the spring is connected to the top block, and the top block can slide along the guide well.

The terms "first" and "second" and the like in the specification and claims of this invention and the accompanying drawings are used to distinguish different objects, not to describe a specific order.

[0027] References to "embodiments" herein mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0028] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0029] like Figure 1-4 The following are examples provided by the present invention.

[0030] The embodiment of the present invention provides a rubber sheeting mechanism, comprising: a mounting frame 10, an active pressure roller 20 and a driven pressure roller 30, the active pressure roller 20 and the driven pressure roller 30 being parallel to each other and respectively mounted on two opposite side walls of the mounting frame 10, a driving motor 12 being provided at the inner bottom of the mounting frame 10, a driving gear 13 being connected to the output shaft of the driving motor 12, a driven gear 21 being connected to the roller shaft of the active pressure roller 20, the driving gear 13 being engaged with the driven gear 21, thereby driving the active pressure roller 20 to rotate, the active pressure roller 20 and the driven pressure roller 30 rotating in opposite directions, wherein the pressure roller on the left rotates clockwise and the pressure roller on the right rotates counterclockwise, the gap between the active pressure roller 20 and the driven pressure roller 30 is an extrusion channel for the rubber, the rubber will become a sheet-like rubber sheet after being squeezed by the active pressure roller 20 and the driven pressure roller 30, and the width of the gap between the active pressure roller 20 and the driven pressure roller 30 is the thickness of the rubber sheet after extrusion. Specifically, thin-profile adjustment mechanisms 40 are embedded in two opposing side walls of the mounting frame 10. The two thin-profile adjustment mechanisms 40 are respectively connected to the ends of the driven pressure roller 30. The thin-profile adjustment mechanisms 40 are used to change the gap between the active pressure roller 20 and the driven pressure roller 30. After adopting the above-mentioned rubber sheeting mechanism, the position of the driven pressure roller 30 is controlled by the thin-profile adjustment mechanisms 40 embedded in the two opposing side walls of the mounting frame 10, thereby changing the gap between the active pressure roller 20 and the driven pressure roller 30. Because the thin-profile adjustment mechanisms 40 are relatively thin and embedded in the side walls of the mounting frame 10, they do not compress the installation space of the active and driven pressure rollers 20 and 30. This allows the length of the squeezing rollers to be increased, thereby improving the rubber squeezing width, thereby contributing to improved production efficiency.

[0031] Specifically, the thin adjustment mechanism 40 includes a thin slider 41. A rectangular sliding window 11 is respectively opened on the two opposite side walls of the mounting frame 10. The thin slider 41 is slidably installed in the sliding window 11. It can be understood that the sliding window 11 is similar to the window frame of a window, and the thin slider 41 is equivalent to the window. The upper and lower frames of the sliding window 11 have tracks, so that the thin slider 41 can slide back and forth along the upper and lower tracks, but cannot move up and down; a bearing 44 is installed on the thin slider 41, and the bearing 44 is connected to the roller shaft of the driven pressure roller 30, so that the two ends of the driven pressure roller 30 are respectively rotatably connected to the corresponding thin slider 41. The back and forth sliding of the thin slider 41 can drive the driven pressure roller 30 to move back and forth, and the position of the active pressure roller 20 needs to be as close as possible to one side of the sliding window 11 so that the minimum gap between the driven pressure roller 30 and the active pressure roller 20 can be sufficiently small. It is best that the driven pressure roller 30 and the active pressure roller 20 can be just tangent. In addition, the thin adjustment mechanism 40 also includes an adjusting screw 42, which is arranged in the side wall of the mounting frame 10, and its axis is perpendicular to the driven pressure roller 30. The adjusting screw 42 is connected to the thin slider 41, and is used to adjust the front and rear positions of the thin slider 41 in the sliding window 11. By rotating the adjusting screw 42, the length of the adjusting screw 42 penetrating into the side wall of the mounting frame 10 can be changed, thereby adjusting the position of the thin slider 41, thereby driving the driven pressure roller 30 to approach or move away from the active pressure roller 20, thereby realizing the change of the gap between the driven pressure roller 30 and the active pressure roller 20.

[0032] Furthermore, the axis of the active pressure roller 20, the axis of the driven pressure roller 30 and the axis of the adjusting screw 42 are located in the same plane, which is parallel to the horizontal plane, so that the active pressure roller 20, the driven pressure roller 30 and the adjusting screw 42 are all set in a horizontal state, and the active pressure roller 20 and the adjusting screw 42 are respectively located on both sides of the driven pressure roller 30.

[0033] Furthermore, the inner end of the adjusting screw 42 abuts against one end of the thin slider 41, and the other end of the thin slider 41 is provided with an elastic member 43, and the outer end of the elastic member 43 abuts against the side of the sliding window 11. Specifically, a guide well 411 in the same direction as the adjusting screw 42 is provided in the thin slider 41, and the opening of the guide well 411 faces the active pressure roller 20. The elastic member 43 includes a spring 431 and a top block 432. The inner end of the spring 431 is connected to the inner wall of the guide well 411, and the outer end of the spring 431 is connected to the top block 432. Then, the top block 432 can slide along the guide well 411. When the adjusting screw 42 pushes inward, the thin slider 41 is pressed toward the side of the sliding window 11 near the active roller 20, causing the top block 432 to compress the spring 431 in the guide well 411 until the top block 432 is completely retracted into the guide well 411. When the adjusting screw 42 retracts outward, under the elastic force of the spring 431, the top block 432 pushes the side of the sliding window 11 outward and pushes the thin slider 41 toward the side of the sliding window 11 away from the active roller 20. In addition, the two adjusting screws 42 are respectively located at the two ends of the driven roller 30, so that the two thin sliders 41 balance the forces at the two ends of the driven roller 30 during the sliding process. This makes it difficult for the driven roller 30 to deviate when it extrudes the rubber material together with the active roller 20, and it always remains parallel to the active roller 20, thereby ensuring a more uniform thickness of the extruded film.

[0034] Furthermore, a knob 45 is provided at the outer end of the adjusting screw 42 , and the knob 45 is used to rotate the adjusting screw 42 . The diameter of the knob 45 is larger than that of the adjusting screw 42 , so that the operator can save more effort when rotating the adjusting screw 42 .

[0035] Specifically, a hopper 15 is provided on the top of the mounting frame 10, and a feed port 14 is opened on the top wall of the mounting frame 10. The lower end of the hopper 15 is connected to the feed port 14, and the rubber material falls into the feed port 14 from the hopper 15. The feed port 14 is located between the positive projections of the axis of the active pressure roller 20 and the axis of the driven pressure roller 30 on the top wall of the mounting frame 10, so that the rubber material can just fall into the area between the active pressure roller 20 and the driven pressure roller 30, so that the rubber material can be extruded and formed through the extrusion channel.

The preferred embodiments of the present invention are given in the accompanying drawings, but they do not limit the patent scope of the present invention. The present invention can be implemented in many different forms. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

Any equivalent structure made using the contents of the present invention specification and the accompanying drawings, directly or indirectly used in other related technical fields, is also within the scope of protection of the present invention patent.
