Description

Technical Field

[0001] This utility model relates to the field of plastic covering equipment, and more specifically, to an extrusion-type plastic covering equipment. Background Technology

[0002] In the sea salt production process, covering the crystallization pool with plastic sheeting is an important measure to prevent rainwater from flowing in and to protect the quality of the raw salt and brine.

[0003] Traditional plastic sheet storage relies primarily on manual operation, which is not only labor-intensive and time-consuming, but also makes it difficult to ensure even folding, often resulting in uneven folds. Furthermore, the significant friction between the plastic sheets and the external environment during storage increases wear and tear on the equipment, raising the risk of damage and shortening its lifespan. Therefore, inventing an extrusion-type plastic sheet storage device to address these issues has become a pressing problem for those skilled in the art. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an extrusion-type plastic tarpaulin covering device, which aims to improve the problem that during the plastic tarpaulin covering process, the friction between the plastic tarpaulin and the outside is large, which aggravates the wear of the internal parts of the device, increases the risk of device damage, and shortens the service life of the device.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Please see Figure 1 and Figure 2 This utility model provides a technical solution: an extrusion-type plastic covering device, comprising...

[0024] The main body 1 has a take-up platform 11 at each end. The take-up platform 11 is equipped with a winder 2. The output end of the winder 2 is connected to a straight shaft 3. The straight shaft 3 is connected to a winding 54. The winding 54 is connected to a plastic sheet 62. The winder 2 serves as the power source of the equipment. Through its internal mechanical structure and transmission device, it converts electrical energy or other power into rotational output to drive the straight shaft 3 to rotate, thereby realizing the winding and unfolding operation of the plastic sheet 62.

[0025] Please see Figures 1 to 3 The main body 1 is rectangular in shape, and limiting steel wires 6 are fixedly connected to both sides of the interior of the main body 1. The two ends of the limiting steel wires 6 are fixedly connected to the two ends of the interior of the main body 1. Circular rings 61 are evenly sleeved on the limiting steel wires 6, and the circular rings 61 are located on both sides of the plastic cover 62. Multiple circular rings 61 are equidistantly connected above the plastic cover 62.

[0026] The limiting wire 6 provides precise guidance and limiting for the folding and movement of the plastic cover 62, ensuring that the plastic cover 62 moves along a predetermined trajectory during storage and unfolding, avoiding problems such as deviation and entanglement. The equidistant connection of the rings 61 ensures that the plastic cover 62 forms a regular shape when folded.

[0027] Multiple pairs of windings 54 are provided. One end of each pair of windings 54 is connected to a straight shaft 3 on one side, and the other end of each pair of windings 54 is connected to the plastic cover 62 for transmission. Multiple pairs are used to pull the plastic cover 62 to fold and unfold. At the same time, the design of multiple pairs of windings 54 increases the traction points of the plastic cover 62, making the force distribution more even and avoiding damage to the plastic cover 62 or uneven folding due to excessive force at a single point. A connecting block 4 is fixedly connected to the top of one end of the plastic cover 62. The windings 54 are connected to both sides of the connecting block 4 facing the straight shaft 3. The connecting block 4 serves as the connecting hub between the plastic cover 62 and the windings 54, and plays an important role in transmitting force and guiding the movement of the plastic cover 62. The position and manner in which it is fixed to the plastic cover 62 must ensure that it will not detach from the plastic cover 62 during the force process and can evenly transmit the tension of the windings 54 to the plastic cover 62. Multiple sets of connecting blocks 4 are provided, and these sets of connecting blocks 4 are evenly connected to the ends of the plastic cover 62. A floating plate 41 is provided above the connecting blocks 4. The floating plate 41 is fixedly connected to the multiple sets of connecting blocks 4. The floating plate 41 provides additional support and buoyancy for the connecting blocks 4. During the retraction and unfolding of the plastic cover 62, the floating plate 41 can float within a certain range with the movement of the connecting blocks 4, reducing the downward pressure of the connecting blocks 4 on the plastic cover 62, reducing the friction between the plastic cover 62 and the components below (such as the surface of the crystallization pool, other equipment, etc.), making the operation more effortless and smooth.

[0028] The floating plate 41 is usually made of lightweight materials with a certain strength (such as hollow microsphere composite materials) to achieve buoyancy and support functions while reducing the overall weight of the equipment.

[0029] The bottom of the connecting block 4 is equipped with floating plate connecting frames 52 on both sides facing the straight shaft 3. The floating plate connecting frames 52 are equipped with second rotating wheels 53 for limiting rotation. The bottom of the receiving platform 11 at both ends of the main body 1 is fixedly connected with multiple material platform fixing frames 5. The inside of the multiple material platform fixing frames 5 is equipped with first rotating wheels 51 for limiting rotation. The two ends of a winding wire 54 are fixedly wound around the straight shaft 3, and the middle part of the winding wire 54 passes around the outer circumference of the first rotating wheel 51 and the second rotating wheel 53 in an S-shape.

[0030] The bottom of the connecting block 4 is equipped with floating plate connecting frames 52 on both sides facing the straight shaft 3. The floating plate connecting frames 52 provide installation space and limiting structure for the second rotating wheel 53, ensuring that the second rotating wheel 53 can rotate stably during operation. The internal shape and size of the floating plate connecting frame 52 match the second rotating wheel 53, and it has sufficient strength and rigidity to withstand the tension of the winding 54 and the friction of the second rotating wheel 53 during rotation. The second rotating wheel 53 is rotatably mounted inside the floating plate connecting frame 52. The second rotating wheel 53 plays an auxiliary guiding role and reduces friction during the transmission of the winding 54. When the winding 54 passes around the second rotating wheel 53, the rotation of the wheel changes the direction of the winding 54, making the transmission of tension smoother, while reducing the friction between the winding 54 and the connecting block 4, reducing energy loss and equipment wear. Multiple material platform fixing frames 5 are fixedly connected to the bottom of the receiving platforms 11 at both ends of the main body 1. The material platform fixing frames 5 provide the mounting base for the first rotating wheel 51. The way they are fixedly connected to the bottom of the receiving platform 11 ensures that they will not loosen or shift during the operation of the equipment, thus ensuring the installation stability of the first rotating wheel 51. The first rotating wheel 51 is rotatably mounted inside the multiple material platform fixing frames 5. The first rotating wheel 51 also plays the role of assisting the transmission of the winding 54. During the process of the winding 54 being led out from the straight shaft 3 and connected to the plastic cover 62, the winding 54 passes around the first rotating wheel 51. Through the rotation of the wheel, the direction of the winding 54 is changed, so that the winding 54 can better adapt to the structural layout of the equipment and reduce the friction between the winding 54 and the bottom of the receiving platform 11. Both ends of the winding 54 are fixedly wound around the straight shaft 3 to ensure that the winding 54 can stably perform winding and unwinding actions when the straight shaft 3 rotates, without slipping or falling off. At the same time, the fixing and winding method of the winding 54 needs to facilitate installation and disassembly for equipment maintenance and repair. Meanwhile, the middle part of the winding 54 passes over the outer circumference of the first rotating wheel 51 and the second rotating wheel 53 in an S-shape. The S-shape allows the winding 54 to better utilize the guiding and assisting role of the rotating wheels during transmission, reducing frictional resistance, improving transmission efficiency, and ensuring that the winding 54 is not easily dislodged from the rotating wheels even when subjected to certain external impacts or vibrations during equipment operation, thus ensuring the safe and stable operation of the equipment.

[0031] The outer surface of the limiting wire 6 is smooth. The smooth outer surface can reduce the friction of the ring 61 during the sliding process, making the movement of the ring 61 on the limiting wire 6 smoother, reducing energy loss, and also reducing the wear of the ring 61 and the limiting wire 6, thus extending their service life.

[0032] The plastic sheet 62 features multiple wavy folds. This wavy folding design allows for a more compact arrangement of the plastic sheet 62 during storage, improving storage space utilization. Compared to traditional folding methods, more plastic sheet 62 can be stored within a limited space. Simultaneously, this folding shape offers advantages during unfolding, enabling a smoother return to its original state covering the crystallization tank. This reduces the possibility of wrinkles or jamming during unfolding, ensuring effective coverage of the crystallization tank and protecting the brine and raw salt from external factors.

[0033] Working principle: When the plastic sheet 62 needs to be stored (at this time, the plastic sheet 62 is in the unfolded state), the winding device 2 (designated as winding device A) in one end of the receiving platform 11 is activated. Winding device A drives the straight shaft 3 connected to it to rotate. The winding 54 on the straight shaft 3 begins to be stored as the straight shaft 3 rotates. One end of the winding 54 is fixedly wound around the straight shaft 3, and the middle part passes through the first rotating wheel 51 and the second rotating wheel 53 in an S-shape. The direction of the force is changed by the limiting rotation of the rotating wheels, making the pulling more effortless. The other end of the winding 54 is connected to the connecting block 4 at the end of the plastic sheet 62. The connecting block 4 moves towards the straight shaft 3 under the pull of the winding 54. Since a floating plate 41 is fixedly connected above the connecting block 4, the floating plate 41 provides a certain buoyancy and support for the whole, making its movement smoother. At the same time, the second rotating wheel 53 in the floating plate connecting frame 52 on both sides of the bottom of the connecting block 4 assists in the pulling of the winding 54 and reduces friction. At this time, the winding device 2 (designated as winding device B) in the receiving platform 11 at the other end is in a self-locking released state, and its straight shaft 3 rotates synchronously under the drive of the straight shaft 3 of winding device A, causing the winding 54 on one side of winding device B to unwind. The rings 61 on both sides of the plastic cover 62 slide along the limiting steel wire 6 under the drive of the connecting block 4. Since the rings 61 are equidistantly connected above the plastic cover 62 and the surface of the limiting steel wire 6 is smooth, the plastic cover 62 achieves uniform wave-shaped folding and is neatly stored.

[0034] When the plastic cover 62 needs to be unfolded (at which time the plastic cover 62 is in a folded state), the B winding device is activated, causing its straight shaft 3 to rotate in the opposite direction. The previously loosened winding 54 begins to be wound up, while the A winding device enters a self-locking release state. Its straight shaft 3 rotates in the opposite direction under the drive of the B winding device's straight shaft 3, causing the winding 54 on one side of the A winding device to loosen. The reverse movement of the winding 54 pulls the ring 61 through the connecting block 4, causing the plastic cover 62 to slide in the opposite direction along the limiting steel wire 6, gradually unfolding back to the state of covering the crystallization pool. The entire process is the reverse of the winding process, with all components working together to ensure a smooth and orderly unfolding.

[0035] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
