Description

Technical Field

[0001] This utility model relates to the field of composite rigid film production, and in particular to a flattening device for composite rigid film production. Background Technology

[0002] PVDC is one of the packaging materials with the best overall barrier properties, including water, oxygen, and odor resistance. It plays a crucial role in pharmaceutical packaging engineering and is commonly used in blister packaging and composite films. PVDC composite rigid sheets need to be flattened during the cooling and winding process.

[0003] A search revealed a PVDC composite sheet flattening device in Chinese Patent Publication No. CN222522010U. This patent includes a base frame, a motor, a first pressure roller, and a second pressure roller. The motor is connected to the upper right side of the base frame, and the first pressure roller is rotatably connected to the lower part of the base frame. The motor output shaft is connected to the first pressure roller, and the second pressure roller is rotatably and slidably connected to the middle of the base frame. This device improves the flattening effect of the PVDC composite sheet by introducing cooling water into a water pipe and then activating a second automatic lifting mechanism. This causes the upper pressure plate to move downwards to cooperate with the lower pressure plate, pressing the PVDC composite sheet. This achieves the effect of improving the flattening effect and increasing the cooling area of ​​the PVDC composite sheet, thus improving cooling efficiency. However, current composite sheet flattening devices often use a one-time flattening action, resulting in excessive stress on the composite sheet in a short time, affecting the flattening effect and increasing the possibility of breakage and cracks in the composite sheet, leading to a decrease in the yield rate of finished products. Furthermore, it is difficult to handle the flattening operation of composite sheets with different thickness requirements. Utility Model Content

[0004] The purpose of this invention is to provide a flattening device for the production of composite rigid sheets in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

A flattening mechanism is provided on the mounting blocks, comprising two sets of symmetrically arranged first and second flattening rollers and a power assembly. The two second flattening rollers... The gap between the flat rollers is greater than the gap between the first and second flat rollers. The first and second flat rollers are rotatably connected to the mounting block. An adjustment mechanism is provided on the side of the mounting frame to adjust the gap between the first and second flat rollers. A limit mechanism is provided on the mounting frame, which includes two symmetrically arranged limit plates. The limit plates are sleeved on the first and second flat rollers. A blower mechanism is provided on the mounting frame, which includes a blower head. The blower head is installed on one side of the mounting frame.

[0007] Preferably, the power assembly includes two electric motors, which are fixedly connected to the rotating plate. The output shaft of the electric motor is fixedly connected to the first flattening roller. A synchronous belt is fitted on the output shaft of the electric motor, and a transmission shaft is fitted on the other end of the synchronous belt. The transmission shaft is fixedly connected to the second flattening roller.

[0008] Preferably, the ends of the No. 1 and No. 2 flattening rollers away from the mounting block are rotatably connected to guide plates, and arc-shaped columns are slidably connected to the guide plates, with the arc-shaped columns fixedly connected to the mounting frame.

[0009] Preferably, the adjusting mechanism includes a fixed plate, a first bidirectional lead screw rotatably connected to the fixed plate, two adjusting blocks symmetrically arranged vertically connected to the first bidirectional lead screw, a sliding shaft fixedly connected to the adjusting blocks, and the sliding shaft movably arranged inside the rotating plate.

[0010] Preferably, a guide rod is slidably connected to the limiting plate, the guide rod is fixedly connected to the inside of the mounting frame, and a second bidirectional screw is threadedly connected to the limiting plate, the second bidirectional screw being rotatably connected inside the mounting frame.

A pressure plate is fixedly connected to the output end of the hydraulic cylinder.

[0013] The beneficial effects are as follows: The flattening mechanism and the adjustment mechanism are set up. By setting up two sets of No. 1 flattening rollers and No. 2 flattening rollers, the composite rigid sheet is flattened twice during production, and the flattening gap gradually decreases, which avoids damage to the composite rigid sheet during flattening and can also improve the flattening effect. The adjustment mechanism can adapt to the flattening operation of composite rigid sheets with different thickness requirements, which improves the applicability.

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

[0026] like Figure 1 — Figure 6As shown, a flattening device for producing composite rigid sheets includes a mounting frame 101. A mounting plate 102 and a fixed plate 103 are bolted to the mounting frame 101. A connecting mechanism is provided on the mounting frame 101, including a mounting shaft 201 bolted to the side of the mounting plate 102. Two connecting arms 202 are connected to the mounting shaft 201 via bearings. A mounting block 203 is bolted to the end of each connecting arm 202 away from the mounting shaft 201. The mounting blocks 203 are symmetrically arranged vertically. A rotating plate 204 is bolted to the end of each mounting block 203 away from the connecting arms 202. A flattening mechanism is provided on the mounting blocks 203, including two sets of symmetrically arranged flattening rollers 301 and 302, and a power source. The assembly has a gap between two second-level flattening rollers 302 that is larger than the gap between first-level flattening rollers 301. First-level flattening rollers 301 and second-level flattening rollers 302 are rotatably connected to mounting block 203. An adjustment mechanism is provided on the side of mounting frame 101 to adjust the gap between first-level flattening rollers 301 and second-level flattening rollers 302. A limit mechanism is provided on mounting frame 101, which includes two symmetrically arranged limit plates 501. The limit plates 501 are sleeved on first-level flattening rollers 301 and second-level flattening rollers 302. A blower mechanism is provided on mounting frame 101, which includes a blower head 603. The blower head 603 is installed on one side of mounting frame 101. A cooling mechanism is provided on fixing plate 103 and is located at the rear of mounting frame 101.

[0027] In this embodiment, the power assembly includes two electric motors 303. The electric motors 303 are commonly used servo motors on the market and are not limited here. The electric motors 303 are bolted to the rotating plate 204. The output shaft of the electric motor 303 is connected to the first flattening roller 301 through a coupling. A synchronous belt 304 is sleeved on the output shaft of the electric motor 303. A transmission shaft 305 is sleeved on the other end of the synchronous belt 304. The transmission shaft 305 is bolted to the second flattening roller 302. When the electric motor 303 starts, the output end of the electric motor 303 directly drives the first flattening roller 301 to rotate. At the same time, the synchronous belt 304 drives the transmission shaft 305 to rotate. The transmission shaft 305 drives the second flattening roller 302 to rotate synchronously with the first flattening roller 301. During the process of passing through the second flattening roller 302 and the first flattening roller 301, the composite rigid sheet is flattened in two stages in a progressive manner, which improves the yield and flattening effect of the composite rigid sheet.

[0028] In this embodiment, a guide plate 306 is rotatably connected to the ends of the first flattening roller 301 and the second flattening roller 302 away from the mounting block 203. An arc-shaped column 307 is slidably connected to the guide plate 306. The arc-shaped column 307 is bolted to the mounting frame 101. The arc-shaped column 307 is located on the side of the mounting frame 101 away from the mounting block 203. The guide plate 306 and the arc-shaped column 307 can limit and support the ends of the first flattening roller 301 and the second flattening roller 302 away from the mounting block 203.

[0029] In this embodiment, the adjustment mechanism includes a fixed plate 401, on which a first bidirectional lead screw 402 is rotatably connected. Two symmetrically arranged adjustment blocks 403 are threaded onto the first bidirectional lead screw 402. A sliding shaft 404 is welded onto each adjustment block 403. The sliding shaft 404 is movably disposed within the rotating plate 204. Rotating the first bidirectional lead screw 402 causes the two adjustment blocks 403 to move closer or further apart. The adjustment blocks 403 drive the rotating plate 204 to move via the sliding shaft 404. The rotating plate 204 rotates around the mounting shaft 201, thereby changing the distance between the mounting blocks 203. This changes the distance between the first flattening roller 301 and the second flattening roller 302, and always maintains that the gap between the first flattening roller 301 is larger than the gap between the second flattening roller 302.

[0030] In this embodiment, a guide rod 502 is slidably connected to the limiting plate 501. The limiting plate 501 has two arc-shaped grooves for accommodating the first flattening roller 301 and the second flattening roller 302. Lateral movement of the limiting plate 501 will not affect the movement of the first flattening roller 301 and the second flattening roller 302. The guide rod 502 is bolted to the inner side of the mounting frame 101. A second bidirectional lead screw 503 is threaded onto the limiting plate 501. The second bidirectional lead screw 503 is rotatably connected inside the mounting frame 101. The limiting plate 501 limits the two sides of the composite hard sheet.

[0031] In this embodiment, the blower mechanism includes a blower 601, which is bolted to the side of the mounting bracket 101. An air supply pipe 602 is inserted into the air outlet of the blower 601, and the end of the air supply pipe 602 away from the blower 601 is bolted to the blower head 603.

[0032] In this embodiment, the cooling mechanism includes a heat-conducting plate 701, which is bolted to the rear end of the mounting bracket 101. A cold water pipe 702 is bolted inside the heat-conducting plate 701 and connected to an external cold water supply device to provide a cold source for forced cooling of the heat-conducting plate 701 and the composite rigid sheet. The cooling mechanism also includes a hydraulic cylinder 703, which is bolted to the fixing plate 103. The output end of the hydraulic cylinder 703 is bolted to a pressure plate 704.

[0033] Working Principle: In use, the composite sheet is guided from the front of the mounting frame 101 into the first flattening roller 301. The distance between the first flattening roller 301 and the second flattening roller 302 is adjusted according to the required flattening. During adjustment, the first bidirectional lead screw 402 is rotated, causing the two adjusting blocks 403 to move closer or further apart. The adjusting blocks 403, via the sliding shaft 404, drive the rotating plate 204 to rotate around the mounting shaft 201, thus changing the distance between the mounting blocks 203. This alters the distance between the first flattening roller 301 and the second flattening roller 302, ensuring that the gap between the first flattening roller 301 is always larger than the gap between the second flattening roller 302. At the start of the flattening operation, the motor 303, blower 601, and hydraulic cylinder 703 are started. When the motor 303 starts… The output of the motor 303 directly drives the first flattening roller 301 to rotate. At the same time, the synchronous belt 304 drives the transmission shaft 305 to rotate. The transmission shaft 305 drives the second flattening roller 302 to rotate synchronously with the first flattening roller 301. During the process of the composite rigid sheet passing through the second flattening roller 302 and the first flattening roller 301, the composite rigid sheet is flattened in two stages in a progressive manner. Between the two flattening actions, the blower 601 blows air into the blower head 603 through the air supply pipe 602. The blower head 603 provides forced air cooling to the composite rigid sheet, further improving the cooling and flattening effect. After the composite rigid sheet passes through the second flattening roller 302, it reaches the heat-conducting plate 701. At this time, the hydraulic cylinder 703 presses down the pressing plate 704. The pressing plate 704 presses the composite rigid sheet onto the heat-conducting plate 701, providing forced cooling to the composite rigid sheet. This is how the flattening work of composite rigid sheet production is carried out.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. 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. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
