Description

Technical Field

[0001] This utility model relates to the field of solvent-free laminating machine technology, and in particular to a solvent-free production device for environmentally friendly pharmaceutical packaging composite films. Background Technology

[0002] Solvent-free laminating machines are a method of bonding two or more substrates together using solvent-free adhesives; also known as reactive lamination. Equipment suitable for solvent-free adhesive lamination is called a solvent-free laminating machine. Solvent-free laminating is an environmentally friendly and economical process for producing flexible packaging composite materials, offering significant advantages in economy, safety, and environmental protection. This process is currently very popular in Europe and America. With increasing domestic demands for environmental protection and energy conservation, the application of solvent-free laminating machines is also significantly increasing. Solvent-free laminating machines are required in the production of environmentally friendly pharmaceutical packaging composite films.

[0003] In the prior art, such as Chinese Patent No. CN220641997U, a solventless laminating machine is disclosed. This machine includes a laminating body that uses a solventless adhesive to laminate various composite packaging film substrates together. Above the discharge end, a baffle is provided to block external debris during discharge. A support is rotatably connected to one side of the baffle. A connecting assembly is provided between the support and the laminating body, and a support assembly is provided between the support and the baffle for auxiliary support. By using a rotating shaft to connect the baffle and the support, and the receiving plate and the locking block, the receiving plate and the baffle can be flipped and folded around their corresponding rotating shafts. When not in use, the receiving plate and the baffle can be folded and stored to reduce the space occupied by the solventless laminating machine. For the next use, simply flip and open the baffle and the receiving plate sequentially, and use the support assembly for auxiliary support, thus improving the convenience of future use.

[0004] While the above-mentioned solution has the advantages mentioned above, its disadvantages are as follows: although it can use rotating shafts to connect the baffle and support, and the receiving plate and the locking block, allowing the receiving plate and baffle to be flipped and folded around their respective shafts, thus reducing the space occupied by the solventless laminator when not in use, the storage of the baffle and receiving plate requires separate operation, which is relatively troublesome, resulting in low storage efficiency for the baffle and receiving plate. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the existing technology that, although the baffle and support, and the receiving plate and the locking block are all connected by rotating shafts, allowing the receiving plate and baffle to be flipped and folded around their corresponding rotating shafts, so that the receiving plate and baffle can be folded and stored when the solventless laminator is not in use, thereby reducing the space occupied by the solventless laminator, the storage of the baffle and receiving plate requires separate operation, which is relatively troublesome, resulting in low storage efficiency of the baffle and receiving plate.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a solvent-free production device for environmentally friendly pharmaceutical packaging composite films, comprising: a solvent-free laminating machine body, and further comprising:

[0007] A U-shaped frame is installed on one side of the solvent-free laminating machine body. Fixed blocks are fixedly connected to one side of each of the two arms of the U-shaped frame. A movable plate is rotatably connected to the opposite side of the two fixed blocks. A second sliding groove is opened on one side of the U-shaped frame. A bidirectional lead screw is rotatably connected to the opposite side of the inner wall of the second sliding groove. Two threaded blocks are symmetrically threaded onto the outer surface of the bidirectional lead screw. A motor is fixedly connected to the bottom of the U-shaped frame. The output end of the motor is fixedly connected to one end of the bidirectional lead screw. An H-shaped plate is rotatably connected to the opposite side of the threaded blocks via a support rod. Two second U-shaped blocks are symmetrically fixedly connected to one side of the U-shaped frame. An L-shaped strip is rotatably connected to the opposite side of the two arms of the second U-shaped blocks via a support rod. The L-shaped strip and the H-shaped plate are rotatably connected via a support rod. A round rod is fixedly connected to one side of the L-shaped strip. A first sliding groove is opened on one side of the movable plate. One end of the round rod is slidably connected inside the first sliding groove.

[0008] Preferably, two U-shaped plates are symmetrically fixedly connected to one side of the solventless laminating machine body, and the two arms of the U-shaped frame are slidably connected inside the two U-shaped plates respectively.

[0009] Preferably, a U-shaped block is fixedly connected to the other side of the solventless laminating machine body, and a limit block is slidably connected to the top of the U-shaped block.

[0010] Preferably, two guide rods are symmetrically fixedly connected to the top of the U-shaped block, the limiting block is slidably connected to the two guide rods, and a spring is provided on the outer surface of the guide rod, the spring being fixedly connected to the limiting block and the guide rod respectively.

[0011] Preferably, a plug is fixedly connected to one side of the center of the U-shaped frame, the top of the plug has a limiting groove, and the bottom of the limiting block is slidably connected inside the limiting groove.

[0012] Preferably, one side of the insert block is provided with a first inclined surface, and the bottom of the limiting block is provided with a second inclined surface.

[0013] Preferably, the width of the threaded block is equal to the width of the inner wall of the second groove, and a silicone pad is fixedly connected to the top of one of the movable plates.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. This utility model controls the motor to start via a controller, causing its output shaft to drive the bidirectional lead screw to rotate. Then, with the cooperation of the bidirectional lead screw and the threaded block, and with the limiting and guiding of the threaded block by the second slide groove, the threaded block can move towards the center along the outer surface of the bidirectional lead screw, applying a pulling force to the H-shaped plate, which in turn applies a pulling force to the L-shaped strip. This causes the two ends of the H-shaped plate to rotate around the threaded block and the L-shaped strip at appropriate angles via support rods, causing the L-shaped strip to rotate towards the center via the support rods. The included angle between the H-shaped plate and the L-shaped strip gradually increases, synchronously driving the round rod to move. The round rod slides a suitable distance inside the first slide groove and applies a force to the movable plate, causing the silicone pad to rotate towards the solventless laminating machine body at an appropriate angle via the support rods. In this way, the two movable plates can be stored simultaneously without separate operation, which is simple and improves the efficiency of movable plate storage.

[0016] 2. In this utility model, by manually pulling the limiting block upwards, it slides upwards along the outer surface of the guide rod, simultaneously compressing the spring and causing the limiting block to disengage from the limiting groove, thus releasing the limiting of the insert block. At this point, the insert block can be removed from the inside of U-shaped block one, and the U-shaped frame can be pulled out from the inside of U-shaped plate, thus completing the disassembly of the movable plate. Conversely, inserting the U-shaped frame into U-shaped plate causes the insert block to be inserted into U-shaped block one, so that the inclined surface one of the insert block contacts the inclined surface two of the limiting block, and applying a pressure to the limiting block. The upward thrust causes the limiting block to slide upward, simultaneously compressing the spring. When the insert is fully embedded in the U-shaped block, the limiting block moves directly above the limiting groove. Under the restoring force of the spring, the limiting block can be inserted into the limiting groove to limit the insert, thereby limiting the U-shaped frame. This makes it easy to disassemble or install the movable plate, which is simple and convenient. Moreover, the insert is located in the middle of the solventless laminating machine body at a moderate height, making it convenient for workers to disassemble. Attached Figure Description

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Examples, such as Figure 1-4As shown, this utility model provides a solvent-free production device for environmentally friendly pharmaceutical packaging composite films, including: a solvent-free laminating machine body 1, and a U-shaped frame 201, which is disposed on one side of the solvent-free laminating machine body 1. Fixed blocks 202 are fixedly connected to one side of each of the two arms of the U-shaped frame 201. Movable plates 203 are rotatably connected to the opposite sides of the two fixed blocks 202. A second sliding groove 206 is opened on one side of the U-shaped frame 201. A bidirectional lead screw 4 is rotatably connected to the opposite side of the inner wall of the second sliding groove 206. Two threaded blocks 402 are symmetrically threaded onto the outer surface of the bidirectional lead screw 4. The bottom of the U-shaped frame 201 is fixed... A motor 401 is connected, and the output end of the motor 401 is fixedly connected to one end of the bidirectional lead screw 4. An H-shaped plate 403 is rotatably connected to the opposite side of the threaded block 402 via a support rod. Two U-shaped blocks 404 are symmetrically fixedly connected to one side of the U-shaped frame 201. An L-shaped strip 405 is rotatably connected to the opposite side of the two arms of the U-shaped block 404 via a support rod. The L-shaped strip 405 and the H-shaped plate 403 are rotatably connected via a support rod. A round rod 406 is fixedly connected to one side of the L-shaped strip 405. A sliding groove 205 is opened on one side of the movable plate 203. One end of the round rod 406 is slidably connected inside the sliding groove 205.

[0026] Furthermore, such as Figure 1-4 As shown, two U-shaped plates 2 are symmetrically fixedly connected to one side of the solventless laminating machine body 1. The two arms of the U-shaped frame 201 are slidably connected inside the two U-shaped plates 2. With the above arrangement, when the U-shaped frame 201 is inserted into the U-shaped plate 2, the U-shaped frame 201 can be supported by the U-shaped plate 2.

[0027] Furthermore, such as Figure 1-4 As shown, a U-shaped block 301 is fixedly connected to the other side of the solventless laminating machine body 1. A limiting block 302 is slidably connected to the top of the U-shaped block 301. With the above-mentioned arrangement, the limiting block 302 can slide up and down along the inside of the U-shaped block 301.

[0028] Furthermore, such as Figure 1-4 As shown, two guide rods 303 are symmetrically fixedly connected to the top of the U-shaped block 301. The limiting block 302 is slidably connected to the two guide rods 303. A spring 304 is provided on the outer surface of the guide rod 303. The spring 304 is fixedly connected to the limiting block 302 and the guide rod 303 respectively. Under the reset force of the spring 304, the limiting block 302 can slide downward along the outer surface of the guide rod 303.

[0029] Furthermore, such as Figure 1-4 As shown, a plug 3 is fixedly connected to one side of the center of the U-shaped frame 201. A limiting groove 305 is opened on the top of the plug 3. The bottom of the limiting block 302 is slidably connected inside the limiting groove 305. By inserting the limiting block 302 into the limiting groove 305, the plug 3 can be limited.

[0030] Furthermore, such as Figure 1-4 As shown, one side of the insert block 3 is provided with an inclined surface, and the bottom of the limiting block 302 is provided with an inclined surface. With the above arrangement, when the inclined surface of the insert block 3 comes into contact with the inclined surface of the limiting block 302, an upward pushing force can be applied to the limiting block 302, causing the limiting block 302 to slide upward.

[0031] Furthermore, such as Figure 1-4 As shown, the width of the threaded block 402 is equal to the width of the inner wall of the second slide 206. A silicone pad 204 is fixedly connected to the top of one of the movable plates 203. With the above arrangement, the threaded block 402 can slide up and down along the inside of the second slide 206. The movable plate 203 facilitates the pre-receiving of materials. The silicone pad 204 provides a certain buffering and protection effect when the material falls on the silicone pad 204.

[0032] Working Principle: When the solventless laminating machine body 1 has finished producing environmentally friendly pharmaceutical packaging composite film and will not be used for a period of time, the movable plate 203 can be stored. The controller starts the motor 401, causing its output shaft to drive the bidirectional lead screw 4 to rotate. Then, with the threaded connection between the bidirectional lead screw 4 and the threaded block 402, and with the limiting and guiding action of the sliding groove 206 on the threaded block 402, the threaded block 402 can move along the outer surface of the bidirectional lead screw 4 towards the center, applying a pulling force to the H-shaped plate 403. This causes the H-shaped plate 403 to apply a pulling force to the L-shaped strip 405, causing the two ends of the H-shaped plate 403 to be connected by support rods around the threaded block 402 and... The L-shaped strip 405 rotates at an appropriate angle, causing it to rotate towards the center via the support rod. The angle between the H-shaped plate 403 and the L-shaped strip 405 gradually increases, synchronously driving the round rod 406 to move. The round rod 406 slides a suitable distance inside the slide groove 205, applying a force to the movable plate 203. This causes the silicone pad 204 to rotate towards the solventless laminating machine body 1 via the support rod at an appropriate angle. This allows for the simultaneous storage of both movable plates 203 without separate operation, simplifying the process and improving the efficiency of movable plate 203 storage. Conversely, the two movable plates 203 can be unfolded, with the upper movable plate 203 used as a baffle, and the lower movable plate 203... 03 is used as a receiving plate. When it is necessary to remove the movable plate 203 from the top of the solventless laminating machine body 1, the limiting block 302 is pulled upward by hand, causing it to slide upward along the outer surface of the guide rod 303. At the same time, the spring 304 is compressed, causing the limiting block 302 to disengage from the inside of the limiting groove 305, releasing the limiting of the insert 3. At this time, the insert 3 can be removed from the inside of the U-shaped block 301, and the U-shaped frame 201 can be pulled out from the inside of the U-shaped plate 2, thus completing the disassembly of the movable plate 203. Conversely, the U-shaped frame 201 is inserted into the U-shaped plate 2, so that the insert 3 is inserted into the U-shaped block 301, and the inclined surface of the insert 3 is aligned with the limiting block 305. The inclined surfaces of the two contacts 2 and apply an upward pushing force to the limiting block 302, causing the limiting block 302 to slide upward. Simultaneously, the spring 304 is compressed. When the insert 3 is fully embedded in the U-shaped block 301, the limiting block 302 moves directly above the limiting groove 305. Under the reset force of the spring 304, the limiting block 302 can be inserted into the limiting groove 305 to limit the insert 3, thereby limiting the U-shaped frame 201. This makes it easy to disassemble or install the movable plate 203, which is simple and convenient. Moreover, the insert 3 is located in the middle of the solventless laminating machine body 1 at a moderate height, making it convenient for workers to perform disassembly operations.

[0033] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
