Description

Technical Field

[0001] This application relates to the field of calender processing technology, and in particular to a trimming mechanism for a calender. Background Technology

[0002] In the rubber processing industry, calenders are mainly used to calender materials such as rubber into sheets of a certain thickness and width to meet the needs of subsequent production and processing. After the rubber calendering operation is completed, in order to ensure that the quality and appearance of the rubber sheet meet the requirements, it is usually necessary to cut both sides of the rubber to make its edges flush.

[0003] However, most existing calender trimming mechanisms are fixedly installed. This fixed trimming mechanism has certain limitations, making it inconvenient to flexibly adjust according to the actual calendering conditions of the rubber. In actual production, the calendering of rubber is affected by various factors, such as batch differences in raw materials, fluctuations in calendering process parameters, and changes in equipment operating status. These factors can all lead to varying degrees of deviation in the thickness, width, and edge shape of the rubber sheet.

[0004] When the actual size of the rubber sheet does not match the cutting size set by the fixed edge cutting mechanism, the edges of the cut rubber sheet may be uneven. On the other hand, since the position and angle of the cutting blade cannot be adjusted in real time according to the calendering of the rubber, the fit between the cutting blade and the rubber sheet may be poor, affecting the performance.

[0005] To address the aforementioned issues, a trimming mechanism for a calender is now designed. Utility Model Content

[0006] This application provides a trimming mechanism for a calender, which solves the problem that most existing trimming mechanisms for calenders in the related art adopt a fixed installation method, making it inconvenient to flexibly adjust them according to the actual thickness or width of the rubber.

[0007] In a first aspect, a trimming mechanism for a calender is provided, comprising:

[0008] The frame has multiple guide rollers rotating at its top center, with gaps between adjacent guide rollers. The multiple guide rollers are arranged along the length of the frame to guide the calendered material.

[0009] Two cutting blades are arranged opposite each other above the guide roller. The cutting blades cut the material. The cutting blades are equipped with rotating parts. The frame is equipped with a driving part located above the rotating parts. The driving part is connected to the two rotating parts and is used to drive the two cutting blades to move closer or further away. The rotating parts are used to drive the cutting blades to rotate and fit with the material.

[0010] The recycling mechanism includes a recycling bin located at the bottom of the frame and two vacuuming units located opposite each other on the frame.

[0011] In some embodiments, the drive component includes columns on both sides of the frame, a housing between the tops of the two columns, and a double-threaded rod rotatably disposed inside the housing, the threads on the double-threaded rod being opposite in direction;

[0012] A drive motor and a reducer are provided on one side of the housing. The output shaft of the drive motor is connected to the input shaft of the reducer, and the output shaft of the reducer is connected to either end of a double-threaded rod.

[0013] The double-ended threaded rod is threaded with two collars, and a transmission rod is provided at the bottom of the collars. A through hole is provided at the bottom of the housing, and the bottom end of the transmission rod extends outward through the through hole.

[0014] In some embodiments, the drive component includes columns on both sides of the frame, a housing between the tops of the two columns, and a double-threaded rod rotatably disposed inside the housing, the threads on the double-threaded rod being opposite in direction;

[0015] A drive motor and a reducer are provided on one side of the housing. The output shaft of the drive motor is connected to the input shaft of the reducer, and the output shaft of the reducer is connected to either end of a double-threaded rod.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] This application provides a trimming mechanism for a calender, which solves the problem that most existing trimming mechanisms for calenders in related technologies adopt a fixed installation method, making it inconvenient to flexibly adjust them according to the actual thickness or width of the rubber.

[0033] Please see Figures 1-3 A trimming mechanism for a calender includes: a frame 1 with multiple guide rollers 2 rotatably mounted at its upper center, with gaps between adjacent guide rollers 2, the multiple guide rollers 2 being arranged along the length of the frame 1 to guide the calendered material; two cutting blades 3 arranged opposite each other above the guide rollers 2, the cutting blades 3 trimming the material, the cutting blades 3 being equipped with rotating parts 4, and the frame 1 being equipped with a driving part 5 located above the rotating parts 4, the driving part 5 being connected to the two rotating parts 4 and being used to drive the two cutting blades 3 to move closer or further away, the rotating parts 4 being used to drive the cutting blades 3 to rotate and fit against the material; and a recycling mechanism 6, which includes a recycling box 61 located at the bottom of the frame 1 and two dust collection units 62 arranged opposite each other on the frame 1.

[0034] Multiple guide rollers 2 are arranged along the length of the frame 1. The material continues to move forward under the rotational support of the guide rollers 2. The gap between adjacent guide rollers 2 provides space for the waste material after trimming to fall. At the same time, the guide rollers 2 play a role in stabilizing and guiding the material, ensuring that the material can move forward along the predetermined path.

[0035] When the position of the cutting blade 3 needs to be adjusted according to the actual material conditions, the drive unit 5 starts working, driving the two rotating parts 4 to move closer or further apart, thereby causing the two cutting blades 3 mounted on the rotating parts 4 to also move closer or further apart. Through this adjustment, the cutting blade 3 can be accurately positioned at the location where the material needs to be cut, to accommodate materials with different width requirements.

[0036] When the material reaches the cutting position, the rotating component 4 starts working, driving the cutting blade 3 to rotate. Depending on the thickness of the material and the possible angular deviations or irregular shapes that may exist during the production process, rotating the cutting blade 3 allows it to better fit against the material surface, ensuring good contact between the cutting blade 3 and the material edge, thereby achieving precise edge cutting.

[0037] Waste generated during the cutting process will fall, and the recycling box 61 at the bottom of the frame 1 can collect the falling waste. At the same time, the dust suction unit 62 sucks in the fine waste and dust generated during the cutting process, effectively reducing dust pollution in the production environment and further improving the waste recycling efficiency.

[0038] The drive unit 5 can drive the two cutting blades 3 to move closer or further apart, and the position of the cutting blades 3 can be flexibly adjusted according to the width requirements of different materials to ensure the accuracy of cutting.

[0039] The rotating component 4 drives the cutting blade 3 to rotate and fit into the material. This ensures that the cutting blade 3 is always in close contact with the edge of the material, according to the thickness requirements of different materials. This improves the cutting quality and makes the edges of the cut material neater and smoother.

[0040] This trimming mechanism can be adjusted according to the actual conditions of the material, thus it can be applied to the processing of materials with different specifications and characteristics, greatly improving the versatility and adaptability of the equipment.

[0041] The recycling mechanism 6 enables effective recycling of waste materials. The recycling box 61 can collect most of the falling waste materials, while the dust collection unit 62 can further clean up the fine waste and dust generated during the cutting process, reducing pollution to the production environment.

[0042] like Figure 2 and Figure 4 As shown, in one embodiment, the driving component 5 includes columns 51 on both sides of the frame 1, and a housing 52 is disposed between the tops of the two columns 51. A double-threaded rod 53 is rotatably disposed inside the housing 52, with the threads on the double-threaded rod 53 having opposite directions. A drive motor and a reducer are disposed on one side of the housing 52. The output shaft of the drive motor is connected to the input shaft of the reducer, and the output shaft of the reducer is connected to either end of the double-threaded rod 53. Two collars 54 are threadedly connected to the double-threaded rod 53. A transmission rod 55 is disposed at the bottom of each collar 54. A through hole is opened at the bottom of the housing 52, and the bottom end of the transmission rod 55 extends outward through the through hole. A threaded groove adapted to the double-threaded rod 53 is opened on the inner side of the collar 54.

[0043] After the drive motor starts, its output shaft begins to rotate, transmitting power to the input shaft of the reducer connected to it. The reducer reduces the high-speed rotation of the drive motor output, increasing the output torque and reducing the speed to meet the working requirements of subsequent transmission components.

[0044] The output shaft of the reducer transmits the processed power to the double-threaded rod 53, causing the double-threaded rod 53 to rotate inside the housing 52. Since the threads on the double-threaded rod 53 are in opposite directions, when the double-threaded rod 53 rotates, the two collars 54 threaded to the double-threaded rod 53 will be subjected to opposite thread forces. According to the principle of thread transmission, the collars 54 will move linearly along the axial direction of the double-threaded rod 53, and the two collars 54 will move in opposite directions, that is, one collar 54 moves towards one end of the double-threaded rod 53, and the other collar 54 moves towards the other end of the double-threaded rod 53.

[0045] A transmission rod 55 is provided at the bottom of the collar 54. The bottom end of the transmission rod 55 extends outward through the through hole at the bottom of the housing 52. When the collar 54 moves axially along the double-threaded rod 53, it will drive the transmission rod 55 to move synchronously. The transmission rod 55 is connected to the rotating part 4, which in turn drives the rotating part 4 and the cutting blade 3 set on the rotating part 4 to move, so as to bring the two cutting blades 3 closer or further apart, thereby adjusting the position of the cutting blades 3 according to actual needs to meet the requirements of cutting the edges of materials of different widths.

[0046] By using the threaded transmission method between the double-threaded rod 53 and the collar 54, the movement distance of the collar 54 can be precisely controlled, thereby precisely adjusting the position of the cutting blade 3.

[0047] like Figure 2 and Figure 3 As shown, in one embodiment, the rotating component 4 includes a fixed plate 41 disposed at the bottom end of the transmission rod 55. A rotating disk 42 is rotatably disposed on one side of the fixed plate 41, and a second reducer and a second drive motor are disposed on the other side of the fixed plate 41. The output shaft of the second drive motor is connected to the input shaft of the second reducer, and the output shaft of the second reducer is connected to the rotating disk 42. A fixed rod 43 is disposed on the side wall of the rotating disk 42.

[0048] After the second drive motor starts, its output shaft begins to rotate, transmitting power to the input shaft of the second reducer connected to it. The second reducer reduces the high-speed rotation of the second drive motor, increasing the output torque and reducing the speed to meet the rotation requirements of the rotating disk 42.

[0049] The output shaft of reducer 2 transmits the processed power to the rotating disk 42, thereby driving the rotating disk 42 to rotate on one side of the fixed plate 41. A fixed rod 43 is provided on the side wall of the rotating disk 42, and the cutting blade 3 is mounted on the fixed rod 43. When the rotating disk 42 rotates, it drives the fixed rod 43 to rotate synchronously, which in turn drives the cutting blade 3 mounted on the fixed rod 43 to rotate. By controlling the rotation direction and angle of drive motor 2, the rotation angle of the cutting blade 3 can be precisely controlled, so that the cutting blade 3 can better fit with the material surface and achieve precise cutting.

[0050] The use of reducer 2 can precisely control the rotation angle of the rotating disk 42, and thus precisely control the rotation angle of the cutting blade 3, meeting the angle adjustment needs under different materials and different cutting requirements, improving the adaptability and versatility of the equipment, and enabling it to better cope with various complex cutting conditions.

[0051] like Figure 3 As shown, in one embodiment, the cutting blade 3 includes a disc 31 disposed at the other end of the fixed rod 43. A rotating shaft 32 is rotatably disposed on one side of the disc 31, and a cutting blade 33 is disposed at the other end of the rotating shaft 32. A drive motor 3 is disposed on the other side of the disc 31, and the output shaft of the drive motor 3 is connected to the cutting blade 33. The cutting blade 33 is located above the guide roller 2.

[0052] After the drive motor 3 starts, its output shaft begins to rotate. The output shaft of the drive motor 3 and the cutting blade 33 are connected by a rotating shaft 32 to transmit power. The rotational power generated by the drive motor 3 is transmitted to the cutting blade 33, giving the cutting blade 33 the power to rotate.

[0053] Driven by the third drive motor, the cutting blade 33 rotates at high speed around the shaft 32. When the material is conveyed forward under the guidance of the guide roller 2 and reaches the cutting position, the high-speed rotating cutting blade 33 contacts the edge of the material and cuts the edge of the material through the sharp edge of the cutting blade 33, thus realizing the cutting operation of the material.

[0054] The drive motor directly drives the cutting blade 33 to rotate, enabling it to cut at a high speed, significantly improving cutting efficiency. During continuous production in the calender, this efficient cutting capability ensures that materials are trimmed promptly, without affecting the overall production schedule. The high-speed rotating cutting blade 33 generates significant cutting force, and the cutting process is relatively smooth, resulting in cleaner, smoother edges on the cut material, reducing burrs, serrations, and other defects, thus improving product quality.

[0055] like Figure 6As shown, the recycling box 61 in this embodiment includes a fixed seat 611 arranged below the guide roller 2, a collection box 612 is provided on the fixed seat 611, and a collection hopper 613 is provided on the collection box 612.

[0056] During the trimming process in the calender, waste material generated after the material is cut will fall from the gap between the guide rollers 2 or from the edge of the material. Since the collecting hopper 613 is arranged below the guide rollers 2 and above the collecting box 612, the collecting hopper 613 has a large opening area, which can expand the collection range of waste material. When the falling waste material comes into contact with the collecting hopper 613, the collecting hopper 613 will guide the waste material to the opening of the collecting box 612.

[0057] Guided by the collection hopper 613, the waste enters the collection box 612, which provides a storage space for the waste, collecting the waste generated during the cutting process and preventing the waste from being scattered in the production environment.

[0058] like Figure 5 As shown, specifically, the vacuuming unit 62 includes a box 621 disposed on the side wall of the frame 1. A waste box 622 is inserted inside the box 621. A vacuuming pipe 623 is connected to the box 621. The other end of the vacuuming pipe 623 faces the cutting blade 33. A fan 624 is disposed on the other side of the box 621. The air inlet of the fan 624 is connected to the box 621. A filter screen is disposed on the air inlet of the fan 624.

[0059] When the calender trimming mechanism starts working, the blower 624 starts. After the blower 624 starts running, a negative pressure is generated at its air inlet. Since the air inlet of the blower 624 is connected to the box 621, a negative pressure environment is also formed inside the box 621. One end of the suction pipe 623 is connected to the box 621. Under the action of the negative pressure inside the box 621, the small waste materials and dust generated by the cutting blade 33 during the cutting process will be sucked into the suction pipe 623 and enter the box 621 along the suction pipe 623.

[0060] Waste and dust entering the box 621 will fall into the waste box 622 inserted inside the box 621 under the action of airflow. The waste box 622 plays the role of collecting and storing waste, which facilitates the centralized processing of waste in the future.

[0061] The air inlet of the blower 624 is equipped with a filter screen, which can prevent waste and dust from entering the interior of the blower 624.

[0062] In this embodiment, a side cover is hinged to one side of the box body 621. The waste box 622 can be taken out by opening the side cover, which is convenient for staff to use.
