Description

Technical Field

[0001] This utility model relates to the field of flooring production, and in particular to a calendering device for flooring production. Background Technology

[0002] In the production of flooring, a calender is typically used to press and stretch the flooring to meet standard thickness requirements. A calender consists of two or more rollers arranged in a specific pattern, which press and stretch rubber or plastic into a sheet of a certain thickness and surface shape at a specific temperature.

[0003] A search revealed a Chinese patent publication number CN214820212U, which discloses a four-roll calender for flooring production. This patent includes a frame, with lower double-row rollers rotatably mounted at both ends of one side surface of the frame. An adjusting bracket is slidably mounted on one end surface of the frame, with a central crossbeam fixedly connected to the center of the adjusting bracket's surface. Upper double-row rollers are rotatably mounted on both ends of the adjusting bracket, with the surfaces of the upper double-row rollers rotatably connected to the surfaces of the lower double-row rollers. Each end surface of the adjusting bracket has a mounting groove, and an adjusting hydraulic cylinder is fixedly mounted on the side of the mounting groove. One end of the adjusting hydraulic cylinder is fixedly connected to both ends of the frame. This device greatly improves ease of use and stability, ensuring safe and efficient production. However, existing flooring calendering devices require removing excess material from the edges after calendering the flooring film. Furthermore, they lack dynamic handling measures for sudden thickening of the flooring film, affecting the calendering effect and hindering trimming and subsequent processing. Utility Model Content

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] like Figure 1 — Figure 6As shown, a calendering apparatus for flooring production includes a base 101, a collection box 102 mounted on the base 101, and a lifting frame 103 movably mounted above the base 101. Several guide rods 104 are slidably connected to the four corners of the lifting frame 103, and the bottoms of the guide rods 104 are bolted to the base 101. Several sets of calendering mechanisms are arranged inside the base 101 and the lifting frame 103. Each calendering mechanism includes two symmetrically arranged mounting blocks 201, which are slidably connected to the base 101 and the lifting frame 103 respectively. Several rotating shafts 202 are rotatably connected inside the base 101. Calendering rollers 203 are bolted to the rotating shafts 202. A shock-absorbing component is installed on the mounting block 201. A synchronization mechanism is provided on the mounting block 201 to make several sets of mounting blocks 201 move synchronously. An edge trimming mechanism is provided on the inner side of the base 101. The edge trimming mechanism is used to remove the excess parts on both sides of the floor film of different widths. When the floor film is thicker in a certain place, the edge trimming mechanism will swing, thereby generating a larger cutting force, which helps to improve the neatness of the edge of the floor film.

[0027] In this embodiment, the trimming mechanism includes a bidirectional lead screw 401, which is rotatably connected to the inner side of the base 101. Two movable rings 403 are threaded onto the bidirectional lead screw 401, and a cutting blade 404 is rotatably connected to the movable rings 403. The cutting blade 404 is configured as two parts, namely a ring part and a blade part, and the two parts are integrally formed. The ring part is rotatably mounted on the movable rings 403, and the cutting blade 404 is inclined and the blade part is opposite to the calendering roller 203. After the floor film passes through the calendering roller 203, the cutting blade 404 on the rear side trims the edges of the floor film to ensure that the width of the floor film is consistent with the production plan and that the edges are neat.

[0028] In this embodiment, a swing frame 405 is bolted to the moving ring 403. A push rod 407 is fitted inside the swing frame 405. Connecting rods 406 are bolted to both ends of the push rod 407. The end of the connecting rod 406 away from the push rod 407 is bolted to the mounting block 201. When the thicker part of the floor film passes through the calendering roller 203, the calendering roller 203 will be subjected to extrusion and thrust and move backward. The calendering roller 203 will drive the mounting block 201 to move backward through the rotating shaft 202. During the backward movement of the mounting block 201, the swing frame 405 drives the cutting blade 404 to swing at a certain angle through the connection between the connecting rod 406 and the push rod 407. After the thicker part of the floor film passes through the calendering roller 203, the mounting block 201 returns to its original position. During this process, the cutting blade 404 will swing, thereby generating a greater cutting force on the floor film, which is more conducive to cutting off the edge of the floor film, improving neatness, and having a certain dynamic adjustment capability.

[0029] In this embodiment, the damping component includes a damping rod 207, which is disposed between the base 101 and the mounting block 201 on the lower side. A spring 208 is sleeved on the damping rod 207. The damping rod 207 and the spring 208 can weaken the vibration of the calendering roller 203 and improve the calendering effect.

[0030] In this embodiment, a motor 204 is bolted to one side of the mounting block 201. The motor 204 can be a servo motor to ensure that the two sets of calendering rollers 203 rotate at the same speed and synchronously. The output shaft of the motor 204 is bolted to the rotating shaft 202. A pulley 205 is bolted to the end of the rotating shaft 202 away from the motor 204. A synchronous belt 206 is fitted on the pulley 205. By setting the synchronous belt 206, the two rotating shafts 202 that are on the same horizontal line can rotate synchronously.

[0031] In this embodiment, a hydraulic cylinder 105 is bolted to the top of the lifting frame 103. A groove is provided on the inner side of the mounting block 201 for the output shaft of the hydraulic cylinder 105 to pass through. The output end of the hydraulic cylinder 105 passes through the lifting frame 103 and the upper mounting block 201 and is bolted to the base 101.

[0032] In this embodiment, the synchronization mechanism includes a first connecting block 301 and a second connecting block 302. The first connecting block 301 is bolted to the upper mounting block 201, and the second connecting block 302 is bolted to the lower mounting block 201. A sliding rod 303 is bolted to the top of the second connecting block 302, and the sliding rod 303 is slidably connected to the first connecting block 301.

[0033] Working Principle: In operation, the height of the lifting frame 103 is first adjusted using hydraulic cylinder 105 to match the gap between the upper and lower sets of calendering rollers 203 with the thickness of the floor film to be processed. The floor film to be calendered is then introduced from the front of the device, passes between the two sets of calendering rollers 203, and is then transferred to the next processing step at the rear. Rotating the handle 402 drives the bidirectional lead screw 401 to rotate, adjusting the distance between the two moving rings 403 so that the distance between the cutting blades 404 matches the planned width of the floor film. The motor 204 is then turned on, driving the rotating shaft 202 to rotate. The rotating shaft 202, through pulley 205 and synchronous belt 206, drives another set of rotating shafts 202 to rotate synchronously with the calendering rollers 203. The synchronous rotation of the two sets of calendering rollers 203 performs the calendering operation on the floor film between the rollers 203. After the floor film is calendered, the cutting blade 404 at the rear position cuts both sides of the floor film to keep the sides flat and ensure that the width of the floor film after calendering matches the width planned for production. If a thicker section of the floor film is encountered, the calendering roller 203 will drive the mounting block 201 to move backward via the rotating shaft 202, extending the calendering time of the floor film at that point. During the backward movement of the mounting block 201, the swing frame 405 drives the cutting blade 404 to swing at a certain angle through the connection between the connecting rod 406 and the push rod 407. After the thicker part of the floor film is calendered by the calendering roller 203, the mounting block 201 returns to its original position. During this process, the cutting blade 404 will swing, thereby generating a greater cutting force on the floor film, which is more conducive to cutting off the edges of the floor film, improving neatness, and having a certain dynamic adjustment capability.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
