Description

Technical Field

[0001] This utility model relates to the field of rubber manufacturing, and in particular to a rubber strip cooling and splitting device. Background Technology

[0002] With the rapid and effective development and expansion of the rubber industry, rubber machinery and equipment are also gradually being improved and upgraded, with a progressively higher level of automation. Equipment such as rubber injection molding machines, rubber extrusion machines, extruders, and corner-jointing machines, as well as other rubber extrusion and vulcanization equipment, all have a high degree of automation. These machines require narrow-width (3-20cm wide) rubber strips for continuous feeding to ensure continuous production. The need for such narrow rubber strips is limited by the width of the feed strip inlet on these machines; the width of the feed strip inlet varies between different types of equipment.

[0003] While rubber strips can be produced directly from an open mill, the efficiency is relatively low. For strips around 15-25cm in length, 2-3 strips can be produced at once, with an overall width of 30-50cm, similar to normal rubber sheet width. The overall sheeting efficiency is also similar, maintaining normal production efficiency and progress. However, producing strips between 3-15cm in length presents many practical problems. For strips that are too small (less than 5cm in width), the open mill's blade width is greater than 5cm, making it difficult to produce such narrow strips. Even if they are produced, problems such as breakage, misalignment, and tangling occur during the subsequent cooling and drying process. This makes the process less practical, and the efficiency of producing a single strip is very low. It often takes more than half an hour to produce rubber strips from a batch of rubber material.

[0004] To address the issues of low stripping efficiency and breakage during cooling, a film slitting machine was used to improve efficiency and resolve these problems. However, this approach introduced new challenges. Firstly, slitting film with a slitting machine requires more operators, increasing labor costs. Operators are needed at both ends of the slitting machine for handling and traction, posing significant safety hazards. Secondly, the width of the slitting strips is not uniform, and the strips require secondary packing and barreling by operators, further reducing efficiency and increasing labor costs. Utility Model Content

[0005] The purpose of this invention is to provide a strip cooling and dividing device that solves the problem of inaccurate blade cutting width adjustment.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] This invention provides a rubber strip cooling and dividing device, including a two-roll mill, a cooling assembly, and a cutting assembly. The cooling assembly is disposed between the two-roll mill and the cutting assembly. The two-roll mill is used to produce rubber strips, which are then conveyed to the cutting assembly via the cooling assembly.

[0008] The cooling assembly includes a cooling pool and multiple cooling rollers. The cooling pool is connected to the rubber outlet end of the open mill, and the cooling rollers are connected to the cooling pool.

[0009] The cutting assembly includes a frame, a rotating shaft, a blade, and a motor. The rotating shaft and the motor are mounted on the frame. The rotating shaft is connected to the motor drive end. The blade is mounted on the rotating shaft and is used to cut rubber strips. The rotating shaft is provided with scale markings to indicate the fixed position of the blade.

[0010] Optionally, the cooling assembly further includes a bracket, on which the cooling rollers are rotatably mounted.

[0011] Furthermore, the cooling assembly also includes an air pump, an upper air pipe, and a lower air pipe. The air pump is mounted on the bracket. The upper air pipe and the lower air pipe are connected to the air outlet of the air pump. The air outlet of the upper air pipe is used to align with the upper surface of the adhesive strip, and the air outlet of the lower air pipe is used to align with the lower surface of the adhesive strip.

[0012] Optionally, the cutting assembly further includes a base, on which the frame is mounted, and the base is higher than the height of the cooling rollers.

[0013] Furthermore, the cutting assembly also includes a pressure roller group, which is disposed on the base and located on the glue inlet side of the frame. The pressure roller group includes an upper pressure roller and a lower pressure roller that are rotatably disposed, with the upper pressure roller located above the lower pressure roller. The upper pressure roller and the lower pressure roller are used to abut against the glue strip.

[0014] Furthermore, the cutting assembly also includes a traction roller group, which is disposed on the base and located on the glue outlet side of the frame. The traction roller group includes an upper traction roller and a lower traction roller that are rotatably disposed. The upper traction roller is located above the lower traction roller. The upper traction roller and the lower traction roller are used to clamp and pull the cut narrow glue strip.

[0015] Optionally, the cutting assembly further includes a first rotating column and a second rotating column, which are arranged side by side and rotatably mounted on the frame. The first rotating column and the second rotating column are used to support the adhesive strip, and the blade is located above and between the first rotating column and the second rotating column.

[0016] Furthermore, a cutting zone is formed between the first rotating column and the second rotating column, and the blade is located within the cutting zone.

[0017] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0018] This utility model discloses a strip cooling and dividing device. Because the rotating shaft is equipped with scale markings, when the blade is fixed on the rotating shaft, it can be fixed according to the scale markings. The position of the blade on the rotating shaft can be adjusted according to different width requirements. This eliminates the need for an additional ruler to measure, as measurement may have errors. By aligning and fixing with the scale markings, the adjustment is accurate in one go, thus solving the problem of inaccurate blade cutting width adjustment. Attached Figure Description

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0030] like Figure 1 and Figure 2 and Figure 3 As shown, a rubber strip cooling and dividing device includes a two-roll mill 1, a cooling component 2 and a cutting component 3. The cooling component 2 is disposed between the two-roll mill 1 and the cutting component 3. The two-roll mill 1 is used to produce rubber strips 4, and the rubber strips 4 are conveyed to the cutting component 3 via the cooling component 2.

[0031] The cooling assembly 2 includes a cooling pool 21 and multiple cooling rollers 22. The cooling pool 21 is connected to the rubber outlet end of the open mill 1. The rubber strip 4 coming out of the open mill 1 passes through the cooling pool 21, which contains coolant. The multiple cooling rollers 22 are arranged in a row and are connected to the cooling pool 21. The rubber strip 4 coming out of the cooling pool 21 overlaps the multiple cooling rollers 22. The rubber strip 4 dries as it moves on the multiple cooling rollers 22. The multiple cooling rollers 22 are in rolling contact with the rubber strip 4.

[0032] The cutting assembly 3 includes a frame 31, a rotating shaft 32, a blade 33, and a motor 34. The rotating shaft 32 and the motor 34 are mounted on the frame 31. The rotating shaft 32 is connected to the drive end of the motor 34, and the motor 34 drives the rotating shaft 32 to rotate. The rotating shaft 32 rotates on the frame 31. The blade 33 is mounted on the rotating shaft 32 and rotates together with the rotating shaft 32. The blade 33 is used to cut the rubber strip 4 and moves along the path of the rubber strip 4.

[0033] The rotating shaft 32 is provided with a scale mark 35, which is used to indicate the fixed position of the blade 33. According to the process requirements, a whole sheet of adhesive strip 4 is to be cut into narrow adhesive strips of different widths. The cutting width of the blade 33 is determined according to the width requirement of the narrow adhesive strip. Therefore, before the blade 33 is fixed, the blade 33 must first be aligned with the scale mark 35, and then the blade 33 is fixed.

[0034] The number of blades 33 can be set as needed. The distance between adjacent blades 33 is also determined by the scale markings on the scale mark 35. The distance between adjacent blades 33 is also the width of the narrow strip after cutting.

[0035] The cooling assembly 2 also includes a bracket 23, on which cooling rollers 22 are rotatably mounted. Multiple cooling rollers 22 are arranged side by side and rotatably mounted on the bracket 23. There are gaps between adjacent cooling rollers 22 for ventilation and heat dissipation.

[0036] The cooling assembly 2 also includes an air pump 24, an upper air pipe 25, and a lower air pipe 26. The air pump 24 is mounted on the bracket 23. The upper air pipe 25 and the lower air pipe 26 are connected to the air outlet of the air pump 24. The air outlet of the upper air pipe 25 is aligned with the upper surface of the rubber strip 4, and the air outlet of the lower air pipe 26 is aligned with the lower surface of the rubber strip 4. The rubber strip 4 on the cooling roller 22 is covered with liquid. When the air pump 24 is turned on, the upper air pipe 25 blows air towards the upper surface of the rubber strip 4, and the lower air pipe 26 blows air towards the lower surface of the rubber strip 4. When the rubber strip 4 leaves the cooling roller 22, the rubber strip 4 has been dried.

[0037] The cutting assembly 3 also includes a base 39, and a frame 31 is mounted on the base 39. The base 39 is higher than the height of the cooling roller 22, so that the narrow rubber strip is easy to collect after the blade 33 cuts the rubber strip 4.

[0038] The cutting assembly 3 also includes a pressure roller group 36, which is mounted on the base 39 and located on the glue inlet side of the frame 31. The pressure roller group 36 includes an upper pressure roller 361 and a lower pressure roller 362 that are rotatably mounted. The upper pressure roller 361 is located above the lower pressure roller 362. The upper pressure roller 361 and the lower pressure roller 362 are used to clamp the rubber strip 4. When the rubber strip 4 moves, it drives the upper pressure roller 361 and the lower pressure roller 362 to rotate simultaneously. The upper pressure roller 361 and the lower pressure roller 362 flatten the rubber strip 4, preventing the rubber strip 4 from becoming wavy, which is beneficial for the blade 33 to cut the rubber strip 4.

[0039] The cutting assembly 3 also includes a traction roller group 37, which is mounted on the base 39 and located on the glue outlet side of the frame 31. The traction roller group 37 includes an upper traction roller 371 and a lower traction roller 372 that are rotatably mounted. In this example, a servo motor (not shown in the figure) drives the upper traction roller 371 and the lower traction roller 372 to rotate. The upper traction roller 371 is located above the lower traction roller 372. The upper traction roller 371 and the lower traction roller 372 are used to clamp and pull the cut narrow rubber strip. The upper traction roller 371 and the lower traction roller 372 apply traction force to the cut narrow rubber strip, so that the narrow rubber strip drives the entire rubber strip 4 to move. The rubber strip 4 is cut by the blade 33.

[0040] The cutting assembly 3 also includes a first rotating column 311 and a second rotating column 322. The first rotating column 311 and the second rotating column 322 are arranged side by side and rotatably mounted on the frame 31. The first rotating column 311 and the second rotating column 322 are used to support the adhesive strip 4. When the adhesive strip 4 moves, the first rotating column 311 and the second rotating column 322 can rotate together. The blade 33 is located between the first rotating column 311 and the second rotating column 322. In this way, the adhesive strip 4 is pressed down by the blade 33, so that the adhesive strip 4 is cut in a pressed state.

[0041] Furthermore, a cutting area 38 is formed between the first rotating column 311 and the second rotating column 322, and the blade 33 is located in the cutting area 38. In this example, the cutting area 38 is located between the upper end of the first rotating column 311 and the second rotating column 322 and the center of the two circles. The blade 33 cuts the rubber strip 4 in the cutting area 38. Depending on the thickness of the rubber strip 4, the blade 33 can be replaced with different sizes.

[0042] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the protection scope of this utility model.
