Description

Technical Field

[0001] This utility model belongs to the field of plastic bag production technology, and specifically relates to a drying device for plastic bag production. Background Technology

[0002] Plastic bags are bag-shaped containers mainly used for storing and transporting goods. They can be used to package food, medicine, cosmetics, clothing, and other items for convenient transportation, preservation, and storage.

[0003] During the production process of plastic bags, after the film blowing and bag cutting processes, the plastic bags usually need to be dried using drying equipment to improve the structural stability of the tape. The plastic bags also need to be dried after printing to prevent the patterns or fonts on the plastic bags from peeling off.

[0004] Hot air drying equipment is a common type of plastic bag drying equipment. For example, in the prior art, Chinese utility model patent with authorization announcement number CN222012613U discloses "a drying device for plastic bag production", which includes a conveyor belt. The conveying component provided on the side wall of the conveyor belt includes a driven roller and a driving roller. The driven roller and the driving roller are symmetrically rotatably connected to support columns on their periphery. The driven roller is connected to the driving roller through the conveyor belt. A convex shaft fixed to the end of the driving roller is sleeved with a spur gear on its periphery. The lower surface of the spur gear is meshed with a missing gear, and a rotating shaft is sleeved inside the missing gear.

[0005] While existing drying devices, including those mentioned above, can meet general drying needs, in actual use, the fan always blows hot air only towards the top of the plastic bag, while the bottom and near-bottom parts of the plastic bag are difficult to dry sufficiently, resulting in low processing efficiency. Furthermore, the presence of wrinkles in the feeding assembly when inserting plastic bags of different sizes also affects drying efficiency.

[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0044] Furthermore, by Figure 1 and Figure 2As shown, in this embodiment, the linear screw module 21 is fixed to the top of the drying platform 1, and the mounting frame 22 is fixed to the slide of the linear screw module 21, so that the mounting frame 22 has a degree of freedom of movement in the horizontal direction. The dual-axis cylinder 23 is fixed to the top of the mounting frame 22, and the moving frame 24 is fixed to the output shaft of the dual-axis cylinder 23. The rotating plate 25 is rotatably connected to the moving frame 24, and the rotary cylinder 26 is fixed to the moving frame 24 to drive the rotating plate 25 to rotate. Two moving blocks 27 are symmetrically distributed and movably connected to the rotating plate 25. The tensioning rod 28 is fixed to the moving block 27 and extends into the plastic bag. The driving mechanism 29 is drivably connected to the moving block 27 to drive the two moving blocks 27 to move towards or in opposite directions. With the above scheme, when the plastic bag is processed in the previous station, the linear screw module 21 is started, causing the clamping mechanism 2 to move to the plastic bag outlet. Then the dual-axis cylinder 23 is started, which pushes the moving frame 24 to move, causing the two tensioning rods 28 to move towards or in opposite directions. The bag is inserted into the plastic bag, and then the drive mechanism 29 is activated, driving two moving blocks 27 to move in opposite directions, so that two tensioning rods 28 move in opposite directions to tighten the plastic bag from the inside, ensuring the stability of the plastic bag, and applicable to plastic bags of different sizes; then the dual-axis cylinder 23 restarts, pulling the two tensioning rods 28 back to the initial position, and the lead screw linear module 21 is activated again to transfer the plastic bag to the drying mechanism 3 for drying; during drying, the rotary cylinder 26 is activated, which drives the plastic bag to rotate, so that different sides of the plastic bag are fully dried; after drying, the lead screw linear module 21 transports the plastic bag to the next station. This utility model uses the lead screw linear module 21 to drive the plastic bag to transfer between different stations, the drive mechanism 29 drives the two tensioning rods 28 to move in opposite directions to tighten the plastic bag from the inside, ensuring the stability of the plastic bag, and is applicable to plastic bags of different sizes. The rotary cylinder 26 drives the plastic bag to rotate, and the drying mechanism 3 fully dries different sides of the plastic bag, resulting in high drying efficiency and wide applicability.

[0045] Optionally, by Figure 1 As shown in this embodiment, the drying mechanism 3 includes: a fixed upright plate 31, a top plate 32, and a hot air blower 33. The fixed upright plate 31 is fixed to the top of the drying platform 1, and the top plate 32 is fixed to the top of the fixed upright plate 31. A hole is machined on the top plate 32, and the hot air blower 33 is fixed in the hole. With the above solution, when in use, the hot air blower 33 is connected to a power source to generate hot air and blow the hot air onto the plastic bag to dry the plastic bag.

[0046] In other available embodiments, the hot air blower 33 may also be replaced with a heating lamp.

[0047] Optionally, by Figures 1-3As shown, in this embodiment, the drive mechanism 29 includes: a fixed plate 291, a bidirectional threaded screw 292, and a drive motor 293. The two fixed plates 291 are symmetrically fixed to the outer wall of the rotating plate 25. The bidirectional threaded screw 292 is rotatably installed between the two fixed plates 291 and passes through the moving block 27 and is connected to the moving block 27 by thread engagement. The drive motor 293 is fixed to the fixed plate 291 and is used to drive the bidirectional threaded screw 292 to rotate. With the above scheme, when in use, the drive motor 293 is started to drive the bidirectional threaded screw 292 to rotate. Under the thread engagement, the two moving blocks 27 move towards or in opposite directions, and at the same time drive the two tensioning rods 28 to move.

[0048] Preferably, by Figures 1-3 As shown in this embodiment, the drive mechanism 29 further includes a guide rod 294. The two guide rods 294 are symmetrically fixed between the two fixed plates 291, and the guide rods 294 pass through the moving block 27. With the above solution, the two guide rods 294 are used to guide the moving block 27 during use, which further improves the stability of the moving block 27.

[0049] Preferably, by Figures 1-3 As shown in this embodiment, there are two symmetrically distributed dual-axis cylinders 23. With the above scheme, the design of the two dual-axis cylinders 23 can provide a more stable driving force and also has a more stable support performance, ensuring the stability of the rotating plate 25 and other accessories.

[0050] Preferably, by Figure 1 , Figure 2 and Figure 4 As shown, this embodiment also includes a rubber strip 4, which is fixed to the outer wall of the support rod 28. With the above solution, the rubber strip 4 is flexible during use, and the bag is tightened from the inside by the rubber strip 4, resulting in higher stability and safety.

[0051] Preferably, by Figure 1 , Figure 2 and Figure 4 As shown in this embodiment, the rubber strip 4 is a semi-cylindrical component. With the above solution, the semi-cylindrical rubber strip 4 can effectively avoid scratching the plastic bag during use.

[0052] It is easy to understand that the design of the rubber strip 4 needs to be based on the shape of the plastic bag when it is used. The rubber strip 4 can also be other shapes, such as a rectangular structure. However, to ensure safety, the edges of the rectangular rubber strip 4 need to be rounded.

[0053] Preferably, by Figure 1 , Figure 2 and Figure 4As shown in this embodiment, anti-slip protrusions 41 are evenly distributed on the arc surface of the rubber strip 4. After adopting the above solution, the anti-slip protrusions 41 have an anti-slip effect during use, which further improves the stability of the rubber strip 4 in supporting the plastic bag.

[0057] The working principle and usage process of this utility model: When the drying device of this utility model is in use, after the plastic bag is processed in the previous station, the linear screw module 21 is started, which moves the clamping mechanism 2 to the plastic bag outlet. Then, the dual-axis cylinder 23 is started, which pushes the moving frame 24 to move, so that the two tensioning rods 28 extend into the plastic bag.

[0058] Then the drive mechanism 29 is activated, driving the two moving blocks 27 to move in opposite directions, so that the two tensioning rods 28 move in opposite directions to tighten the plastic bag from the inside, ensuring the stability of the plastic bag, and is suitable for plastic bags of different sizes.

[0059] Then the dual-axis cylinder 23 restarts, pulling the two tensioning rods 28 back to their initial positions, and the lead screw linear module 21 starts again, transferring the plastic bag to the drying mechanism 3 for drying;

[0060] During the drying process, the rotary cylinder 26 is activated, which drives the plastic bag to rotate so as to fully dry different sides of the plastic bag. After drying, the plastic bag is transported to the next station by the lead screw linear module 21.

[0061] This invention uses a lead screw linear module 21 to drive the plastic bag to move between different workstations.
