[0002] As a highly elastic material, rubber plays an important role in various fields of industry and life due to its excellent physical properties and wide applicability. In the production process of rubber products, calendering is a crucial link, which involves pressing and stretching rubber or plastic raw materials into films with specific thickness and surface shape.

[0003] Traditional rubber calenders usually consist of two or more rollers arranged in a certain form and working under certain temperature conditions. However, existing rubber calenders have obvious shortcomings when adjusting the spacing between the calender rollers to meet the production needs of rubber products of different thicknesses. The adjustment process usually requires the removal of various connecting parts, which not only makes the operation process complicated and cumbersome, but also time-consuming and labor-intensive, seriously affecting production efficiency.

[0004] In addition, the rubber needs to be cooled during the calendering process, but the shrinkage of the rubber during the cooling process will cause the thickness of the film to change, which poses a challenge to the stability of product quality. More importantly, when the parameters such as the roller distance of the calender change, causing the thickness of the film to fluctuate, the existing equipment is often unable to detect and adjust in time, which often causes the thickness of the calendered rubber product to fail to meet the preset requirements, thus affecting the overall product quality.

Any modification of the structure, change in the proportion relationship, or adjustment of the size should still fall within the scope of the technical content disclosed by the utility model without affecting the effects and purposes that can be achieved by the utility model. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the utility model. The change or adjustment of their relative relationship should also be regarded as the scope of the implementation of the utility model without substantially changing the technical content.

[0057] like Figure 1-3 As shown, the utility model provides a rubber calendering device, which at least includes: a frame 1, a calendering roller 2, a cooling roller 3 and a thickness monitoring component 4. Among them, a calendering roller 2 is horizontally arranged on the frame 1. A cooling roller 3 horizontally arranged on the frame 1 is provided on one side of the calendering roller. The calendered rubber material is cooled by the cooling roller 3 to ensure the stability of the rubber material in subsequent processing and use. A thickness monitoring component 4 is horizontally arranged on the other side of the cooling roller 3. When in use, the rubber material is first calendered by the calendering roller 2. Subsequently, the calendered film enters the cooling roller 3 to cool the film. The purpose of cooling is to stabilize the film to prevent deformation in subsequent processing or use. The cooled film continues to move forward and enters the working area of ​​the thickness monitoring component 4.

[0058] Specifically, the thickness monitoring assembly 4 includes: an adjustment plate 41 and a fixed plate 42. The inner walls of the two opposite sides of the frame 1 are respectively provided with adjustment plate movable grooves 12 that match the two ends of the adjustment plate 41. The fixed grooves of the adjustment plate 41 are provided with springs 13, and the springs 13 are located above the adjustment plate 41. The adjustment plate 41 is movably arranged in the adjustment plate movable grooves 12 on the inner walls of the two sides of the frame 1, so that the adjustment plate 41 can move up and down along the movable grooves. Further, the two ends of the fixed plate 42 are respectively connected to the inner walls of the two sides of the frame 1, and the fixed plate 42 is located directly below the adjustment plate 41. The fixed plate 42 is fixed on the inner walls of the two sides of the frame 1, providing a stable support surface for the film. The adjustment plate 41 is connected to the frame 1 through the movable groove and has a certain degree of freedom of movement. When the film passes by, it will contact the adjustment plate 41 and push the adjustment plate 41 to move up and down in the movable groove according to its own thickness. Since the spring 13 is provided above the adjustment plate 41, a dynamic balance is formed between the elastic force of the spring 13 and the thickness of the film. The thicker the film, the greater the distance the adjusting plate 41 is pushed downward, and the corresponding increase in the compression of the spring 13. On the contrary, when the film is thinner, the moving distance of the adjusting plate 41 and the compression of the spring 13 are both smaller.

[0059] In one embodiment, a first arc plate 413 that bends upward is provided on one side of the adjustment plate 41, and a second arc plate 421 that bends downward is provided on one side of the fixed plate 42. The first arc plate 413 and the second arc plate 421 make the transition between the film entering the adjustment plate 41 and the fixed plate 42 smoother, reducing the possibility of jamming or folding. In order to facilitate the observation of the film thickness by the branch pipe, a scale groove 14 connected to the fixed groove of the adjustment plate 41 is provided on the cross section of the frame 1, and a scale is provided on the cross section of the frame 1, and the scale is parallel to the scale groove 14. A protrusion 411 extending outward is provided on one side of the adjustment plate 41, and the protrusion 411 matches the scale groove 14, and a scale needle 412 is provided at the end of the protrusion 411. When the adjustment plate 41 moves up and down, the scale needle 412 will move on the scale groove 14 accordingly, so that the thickness value of the film can be read intuitively.

[0060] Combination Figure 1 , Figure 2 , Figure 4 In this device, the roller pitch of the calendering roller 2 can be adjusted to meet the processing requirements of rubber materials of different thicknesses and widths. Specifically, two pairs of roller lifting grooves 11 are arranged oppositely on the inner wall of the frame 1. A hole is arranged at the top of each lifting groove, and a lifting threaded rod 5 is arranged in the hole. A lifting block 6 is threadedly connected to one end of the lifting threaded rod 5. The lifting block 6 has the same width as the lifting groove and can move up and down in the lifting groove. An axial hole 61 is arranged on the lifting block 6 for connecting the calendering roller 2 and the cooling roller 3. The calendering roller 2 includes: a fixed calendering roller 22 and an adjustable calendering roller 21. Both ends of the fixed calendering roller 22 are connected to the frame 1. Both ends of the adjustable calendering roller 21 are connected to a pair of oppositely arranged axial holes 61. Through the connection between the axial hole 61 and the lifting block 6, the adjustable calendering roller 21 can be adjusted up and down with the movement of the lifting block 6. In one embodiment, the adjustable calendering roller 21 is vertically distributed with the fixed calendering roller 22.

[0061] In one embodiment, the cooling roller 3 includes: a fixed cooling roller 32 and an adjustable cooling roller 31, the two ends of the fixed cooling roller 32 are connected to the frame 1, the two ends of the adjustable cooling roller 31 are connected to another pair of oppositely arranged shaft holes 61, and the adjustable cooling roller 31 and the fixed cooling roller 32 are vertically distributed. It is worth noting that the height of the top of the fixed plate 42 is not lower than the top of the fixed cooling roller 32. In a preferred embodiment, the top of the fixed plate 42 and the top of the fixed cooling roller 32 are located on the same horizontal plane. The cooling roller is a roller into which cooling water is passed. When calendering a film or applying an adhesive tape, in order to reduce the deformation caused by the shrinkage of the hot material during cooling, the cooling roller is used to cool it down to reduce the deformation of the material. During operation, the bottom of the film contacts the top of the fixed cooling roller 32 and the top of the fixed plate 42. Since the top of the fixed plate 42 and the top of the fixed cooling roller 32 are located on the same horizontal plane, the film can be in a horizontal state to avoid the influence of the film distortion on the adjustment plate 41.

[0062] like Figure 5 As shown, the rubber calendering device also includes an alarm component to facilitate observation and operation, and can also effectively monitor and warn of abnormal conditions during the rubber calendering process. The alarm component is located in the scale groove 14, and includes: an alarm light 71, a fastening nut 72, a screw 73, a clamping portion 73 and an electric shock sheet 75. One end of the screw 73 is connected to the alarm light; the other end is connected to a battery box 75, and a battery 76 is arranged in the battery box 75. The other end of the battery box 75 is provided with a clamping portion 73, and an electric shock sheet 75 is arranged below the bottom opening of the battery box 75. The two electrodes of the alarm light 71 pass through the screw 73 and are electrically connected to the battery 76 and the electric shock sheet 75 respectively, and the fastening nut 72 matches the screw 73.

[0063] When the thickness of the film exceeds the preset range, the adjusting plate 41 is pushed upward, and the protrusion 411 on the adjusting plate 41 presses the electric contact sheet 75 upward, and the electric contact sheet 75 contacts the electrode at one end of the battery 76 in the battery box 75. At this time, the two electrodes of the alarm light 71 are respectively electrically connected to the battery 76 and the electric contact sheet 75 through the screw 73, forming a closed circuit, so that the alarm light 71 lights up and sends out a warning signal.

[0064] In summary, the utility model effectively overcomes various shortcomings of the prior art and has high industrial utilization value.

[0065] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention.
