Technical Field

[0001] The present application relates to the technical field of film preparation, and in particular to an easy-tear film preparation device. Background Art

[0002] At present, the mixing equipment plays a vital role in the preparation process of easy-tear films. It can put polymers, additives and other auxiliary materials into the equipment according to a certain proportion, and through the rotation and shear force of the stirring blades, the raw materials are efficiently mixed and dispersed inside the equipment. It can be seen that the mixing equipment for easy-tear film preparation is an indispensable key equipment for preparing high-quality easy-tear films. It ensures the uniformity of the composition of the easy-tear film by efficiently mixing and stirring the raw materials, thereby improving the quality and performance of the product;

[0003] At present, during the preparation of the existing easy-tear film, its raw material mixing and stirring equipment has certain defects and shortcomings, and its overall mixing and stirring efficiency is poor. Through searching, the Chinese patent with the Chinese patent announcement number "CN211541909U" discloses a mixing mechanism applied to agricultural plastic film processing, which solves the problem that in the prior art, when the materials are mixed, the materials are mixed only by mixing blades, and the materials are always in the same rotation direction, resulting in uneven mixing of the materials and inconvenience in the later processing of the materials. A mixing mechanism applied to agricultural plastic film processing includes a fixed seat, a driving motor is provided on one side of the top of the fixed seat, a mixing barrel fixedly connected to the fixed seat is provided on one side of the driving motor, a cover plate is provided on the top of the mixing barrel, a discharging plate is provided on the side of the mixing barrel, a driving wheel is fixedly connected to the free end of the output shaft of the driving motor, and a positioning shaft is provided inside the fixed seat. The utility model performs all-round mixing of the materials through the axial rotation of the mixing blades, accompanied by the longitudinal flipping of the materials, and has a good mixing effect, which is convenient for further processing of the later materials.

[0004] With respect to the above-mentioned related technologies, the inventors found the following defects:

[0005] During use, the above-mentioned device only uses a single set of mixing blades to assist in stirring and mixing. However, in its specific stirring and mixing process, it can only mix and stir the bottom of the mixing barrel. During the mixing and stirring, the upper and middle parts of the mixing barrel lack corresponding stirring and mixing structures, and the bottom of the mixing barrel is tilted. Its mixing blades obviously cannot fit the bottom of the mixing barrel. The overall mixture has a certain gap. When mixing, the material at the bottom and the material at the upper end cannot be mixed and stirred efficiently and evenly. It can be seen that the existing equipment does have certain defects and shortcomings, and therefore needs to be improved. Summary of the invention

[0008] The lower stirring mechanism includes a first motor, an auger and a turntable. The first motor is fixedly installed at the lower end of one side of the mixing box. The auger is rotatably connected to the two sides of the lower end of the mixing box. The two sides of the turntable are respectively fixedly connected to the inner side of the auger. The output end of the first motor is fixedly connected to the outer end of an auger. The spiral rotation directions of the auger on both sides of the turntable are opposite to each other. The equipment is equipped with an upper stirring mechanism and a lower stirring mechanism. Through the coordinated stirring up and down, efficient mixing of raw materials can be achieved. The upper stirring mechanism drives the material to roll up and down by the rotation of the stirring plate, while the lower stirring mechanism stirs and mixes the material at the bottom of the mixing box through the auger. The two groups of augers rotate in opposite directions to promote the reciprocating movement of the material in the mixing box, thereby improving the mixing uniformity and Efficiency, the equipment is supported by a base, and the mixing box is located on the top of the base, which is convenient for operation and observation. At the same time, the setting of the support frame increases the stability of the equipment and ensures smooth operation during the mixing process. The equipment is equipped with a lifting mechanism, which can quickly open and close the mixing box by driving the sealing cover up and down, which is convenient for the addition and discharge of materials, as well as the maintenance and cleaning of the equipment. In addition, the design of the discharging mechanism makes the discharging process faster and more convenient. By driving the sealing cover up and down, the scraping frame can be driven to scrape the material on the inner wall of the mixing box. At the same time, the outer side of the auger fits with the arc surface of the bottom of the mixing box, which can scrape the material at the bottom, effectively avoiding the adhesion of materials inside the mixing box, and ensuring the uniformity of mixing and discharging.

[0009] Optionally, the outer surface of the auger is fitted and connected to the bottom of the mixing box, and the overall cross-sectional shape of the auger is set to a circular arc. The outer surface of the auger is fitted and connected to the bottom of the mixing box, and the overall cross-sectional shape of the auger is cleverly set to a circular arc. This design plays a vital role in the easy-to-tear film preparation equipment. First, the fitting connection between the auger and the bottom of the mixing box ensures that there are no dead angles during the mixing process. This tightly fitting design allows the auger to more comprehensively cover the bottom of the mixing box when rotating, thereby avoiding the accumulation or retention of materials at the bottom. In this way, the raw materials in the mixing box can be more evenly and fully stirred, thereby improving the mixing efficiency and quality. Secondly, the circular arc cross-sectional design of the auger enhances its ability to scrape off the bottom material. The circular arc cross-sectional shape not only allows the auger to fit the bottom of the mixing box more smoothly when rotating, but also increases the contact area with the bottom material.

The main function of the lifting mechanism is to enable the sealing cover to move up and down through the driving mechanism, thereby realizing the opening and closing of the mixing box, facilitating the addition of materials, the discharge of mixed materials, and the maintenance and cleaning of the equipment. Specifically, the lifting mechanism includes a side rail, which is fixedly installed in the middle of one side of the mixing box, and is a sliding rod. The movement provides a stable track, and a second motor is fixedly installed at the lower end of the inside of the side rail, which is the power source of the lifting mechanism. By controlling the rotation of the second motor, the lead screw can be driven to rotate inside the side rail. The outer surface of the lead screw is connected to the slide rod by a thread. When the lead screw rotates, the slide rod can slide up and down along the lead screw inside the side rail. This design makes the movement of the slide rod more stable and precise, thereby ensuring that the sealing cover can be opened and closed smoothly. The outer end of the slide rod is fixedly connected to the sealing cover, so when the slide rod moves up and down, it can drive the sealing cover to move together, and by controlling the forward and reverse rotation of the second motor, the sealing cover can be raised and lowered, thereby conveniently opening or closing the mixing box.

[0011] Optionally, the overall cross-sectional shape of the slide bar and the overall cross-sectional shape of the side rail are both set to a convex shape, the outer surface of the slide bar and the inner wall of the side rail are fixedly connected with wear-resistant gaskets, the overall cross-sectional shape of the slide bar and the overall cross-sectional shape of the side rail are both set to a convex shape. This design not only enhances the structural strength of the slide bar and the side rail, but also makes the slide bar more stable when sliding inside the side rail. The convex cross-sectional shape can effectively prevent the slide bar from shifting or shaking during sliding, thereby ensuring the smoothness and accuracy of the movement of the sealing cover. Secondly, the outer surface of the slide bar and the inner wall of the side rail are fixedly connected with wear-resistant gaskets. The presence of the wear-resistant gasket can effectively reduce the friction between the slide bar and the side rail, reduce wear, and thus extend the service life of the equipment.

[0012] Optionally, the side shape of the support frame is set to be an isosceles trapezoid, and the external edges and corners of the support frame are all set to be arc-shaped. First, the side shape of the support frame is set to be an isosceles trapezoid. This design makes the lower part of the support frame wider and the upper part gradually narrows, thereby increasing the stability of the support frame. The isosceles trapezoidal structure enables the support frame to more evenly disperse the forces generated by the weight of the equipment and operation, reducing the pressure on a single point, thereby improving the overall stability of the equipment. Secondly, the external edges and corners of the support frame are all set to be arc-shaped. This design not only makes the appearance of the support frame more beautiful, but more importantly, it reduces stress concentration at the edges and corners, reducing the risk of damage to the equipment when subjected to external forces.

[0013] Optionally, connecting rods are fixedly installed at the four corners of the bottom of the sealing cover, and a scratch frame is fixedly installed at the bottom of the connecting rods, and the outer side of the scratch frame is fit-connected to the inner wall of the mixing box. Connecting rods are fixedly installed at the four corners of the bottom of the sealing cover.

[0014] Optionally, a feed valve is fixedly installed on one side of the top of the sealing cover, and the bottom of the feed valve passes through the sealing cover and is connected to the interior of the mixing box. A feed hopper is fixedly installed on the top of the feed valve, and the bottom of the feed hopper passes through the sealing cover and is connected to the interior of the mixing box through the feed valve. The feed valve is fixedly installed on one side of the top of the sealing cover. This design allows the feed valve to be stably fixed on the sealing cover, ensuring that it will not loosen or fall off during the operation of the equipment. Secondly, the bottom of the feed valve passes through the sealing cover and is connected to the interior of the mixing box. This design allows the raw materials to directly enter the interior of the mixing box through the feed valve for mixing and preparation. In addition, a feed hopper is fixedly installed on the top of the feed valve. The function of the feed hopper is to facilitate the operator to pour the raw materials into the equipment.

[0015] Optionally, a support rod is fixedly installed in the middle of both sides of the top of the base, and a limiting ring frame is fixedly installed in the middle of both sides of the sealing cover, and the limiting ring frame is sleeved on the outer surface of the support rod. Support rods are fixedly installed in the middle of both sides of the top of the base, and the support rods serve as structural supports to ensure the stability and guidance of the sealing cover during movement. This design enables the sealing cover to move along the direction of the support rod when lifting and lowering, avoiding deviation or shaking. Secondly, a limiting ring frame is fixedly installed in the middle of both sides of the sealing cover, and the function of the limiting ring frame is to cooperate with the support rod to limit the movement trajectory of the sealing cover. When the sealing cover is lifted and lowered, the limiting ring frame will be sleeved on the outer surface of the support rod to ensure that the sealing cover moves smoothly along the support rod, thereby improving the overall stability of the equipment.

[0016] Optionally, the discharge mechanism includes a discharge pipe, the input end of the discharge pipe is connected to the interior of the mixing box, a fixing frame is fixedly installed on one side of the discharge pipe, an electric push rod is fixedly installed on the lower end of the fixing frame, a sealing plate is fixedly installed on the output end of the electric push rod, a reserved groove is opened on one side of the discharge pipe, and the sealing plate is inserted into the reserved groove, the input end of the discharge pipe is connected to the bottom of the mixing box, and the input end of the discharge pipe is connected to the interior of the mixing box, so that the material in the mixing box can be discharged smoothly through the discharge pipe.

This design enables the power of the third motor to be evenly distributed to each transmission gear, thereby achieving efficient and stable stirring.

[0018] In summary, this application includes the following beneficial technical effects:

[0019] 1. By setting up the lower stirring mechanism, this equipment can achieve efficient mixing. After the material is added to the mixing box through the feed hopper, the feed valve seal is closed, and the first motor is started to drive the auger to rotate inside the mixing box to assist in stirring and mixing at the bottom. The turntable connects the two groups of augers to ensure synchronous drive. The two groups of augers rotate in opposite directions and rotate in opposite directions to push the material to reciprocate at the bottom of the mixing box to achieve intense mixing and stirring. When driven forward, the material moves inward, and when driven reversely, the material moves to both sides. This reciprocating motion mode significantly improves the mixing and stirring efficiency, ensures that the materials are evenly mixed, and meets the high quality requirements for the preparation of easy-tear films.

[0020] 2. By setting up the upper stirring mechanism, this equipment achieves efficient mixing. When the lower stirring mechanism assists in stirring, the third motor is started to drive the transmission gear to rotate, and then the three sets of rotating shafts are synchronously driven to rotate. Due to the gear meshing transmission characteristics, the rotating shafts on both sides rotate in opposite directions to the middle, and the stirring plates are tilted to drive the materials to roll up and down with the rotation. When the middle stirring plate stirs upward, the stirring plates on both sides stir downward to form an up and down stirring and mixing, ensuring uniform mixing of the materials. Compared with the existing single-group mixing blade design, this equipment achieves more uniform mixing of the materials left and right, up and down through the lateral stirring of the bottom auger and the cooperation of the upper stirring mechanism, which significantly improves the stirring and mixing efficiency.

[0021] 3. By setting up the lifting mechanism and the discharging mechanism, the operation of this equipment is more convenient. After the stirring and mixing is completed, the first motor drives the auger to move the material to the middle of the mixing box, and the electric push rod pulls out the sealing plate to open the discharging pipe to realize rapid discharging. When no sealing is required, the electric push rod can push the sealing plate in. When the equipment needs to be repaired, the second motor drives the lead screw to make the slide bar slide up and down in the side rail. The upward movement of the sealing cover can pull out the upper stirring mechanism and open the mixing box, which is convenient for cleaning and maintenance. At the same time, the sealing cover moves up and down to drive the scraping frame to scrape the material on the inner wall of the mixing box, and the auger fits the bottom arc surface to scrape the bottom material to avoid adhesion and improve the uniformity of mixing and discharging.

The output end of the first motor 31 is fixedly connected to the outer end of an auger 32. The spiral rotation directions of the auger 32 on both sides of the turntable 33 are opposite to each other. The equipment is equipped with an upper stirring mechanism 6 and a lower stirring mechanism 3. Through the coordinated stirring up and down, efficient mixing of the raw materials can be achieved. The upper stirring mechanism 6 drives the material to roll up and down through the rotation of the stirring plate 64, while the lower stirring mechanism 3 stirs and mixes at the bottom of the mixing box 2 through the auger 32. The two groups of augers 32 rotate in opposite directions to push the material to reciprocate in the mixing box 2, thereby improving the mixing efficiency. In order to achieve uniformity and efficiency, the equipment is supported by a base 1, and the mixing box 2 is located on the top of the base 1, which is convenient for operation and observation. At the same time, the setting of the support frame 8 increases the stability of the equipment and ensures smooth operation during the stirring and mixing process. The equipment is provided with a lifting mechanism 4, which can quickly open and close the mixing box 2 by driving the sealing cover 5 to move up and down, which is convenient for the addition and discharge of materials, as well as the maintenance and cleaning of the equipment.

In this way, the auger 32 can more effectively scrape off the bottom material during the stirring process, preventing the adhesion and residue of the material, which not only improves the utilization rate of the material, but also ensures the quality and performance of the prepared easy-tear film. The fitting connection between the outer surface of the auger 32 and the bottom of the mixing box 2 and the design of the arc-shaped cross-section provide a more efficient and uniform stirring effect for the easy-tear film preparation equipment, ensuring that the prepared easy-tear film has excellent quality and performance. This design plays an important role in improving equipment performance and product quality.

[0043] Please refer to Figure 1-Figure 6, the upper stirring mechanism 6 includes a third motor 61 and a transmission gear 62, the third motor 61 is fixedly installed in the middle of the top of the sealing cover 5, the transmission gear 62 is rotatably connected to the bottom of the sealing cover 5 at equal intervals, the transmission gear 62 is arranged in three groups, and two adjacent groups of transmission gears 62 are meshed and connected with each other, a rotating shaft 63 is fixedly installed at the bottom of the transmission gear 62, and a stirring plate 64 is fixedly installed on the outer surface of the rotating shaft 63, and the stirring plate 64 is arranged at an angle. The core components of the upper stirring mechanism 6 include a third motor 61 and a transmission gear 62, the third motor 61 is fixedly installed in the middle of the top of the sealing cover 5 to provide power for the entire stirring mechanism, the transmission gear 62 is rotatably connected to the bottom of the sealing cover 5 at equal intervals, and is arranged in three groups, and the power transmission is realized by meshing connection between two adjacent groups of transmission gears 62. This design makes the third stirring mechanism 6 The power of the three motors 61 can be evenly distributed to each transmission gear 62 to achieve efficient and stable stirring. Secondly, a rotating shaft 63 is fixedly installed at the bottom of each transmission gear 62, and a stirring plate 64 is fixedly installed on the outer surface of the rotating shaft 63. The stirring plate 64 is tilted. This design enables the stirring plate 64 to more effectively scrape and mix the materials at the bottom of the mixing box 2 when rotating. The inclined stirring plate 64 can also generate a certain lifting force during the stirring process to help the materials flow and mix better in the mixing box 2. Driven by the third motor 61, the transmission gear 62 and the stirring plate 64 work together to continuously and evenly stir the materials in the mixing box 2. The design of the upper stirring mechanism 6 not only improves the mixing efficiency, but also ensures the uniformity of material mixing, thereby facilitating the preparation of high-quality easy-to-tear films.

[0044] The implementation principle of the easy-tear film preparation device of the embodiment of the present application is as follows: by setting the lower stirring mechanism 3, the device can be used to open the feed valve 12, and then add the material into the mixing box 2 through the feed hopper 11 during use. After the material is added into the mixing box 2, the feed valve 12 is closed to seal the sealing cover 5, and then the first motor 31 is started to operate, and the first motor 31 is used to drive the auger 32 located inside the mixing box 2 to rotate, which can assist in stirring and mixing the bottom of the mixing box 2. Since the turntable 33 connects the two groups of auger 32, the turntable 33 can be used to connect the two groups of auger 32, so that the two groups can be driven synchronously. When both groups of augers 32 rotate, both groups of augers 32 can rotate to stir both sides of the mixing box 2, and the spiral rotation directions of the two groups of augers 32 are opposite, and the two groups of augers 32 rotate in opposite directions. At this time, the two groups of augers 32 can push the material to reciprocate at the bottom of the mixing box 2. When the first motor 31 drives the auger 32 to rotate in the forward direction, the material inside the mixing box 2 can be driven inward. When the first motor 31 drives the auger 32 to rotate in the reverse direction, the material can be driven toward both sides, so that the material can reciprocate, and the material at the bottom of the mixing box 2 can be mixed and stirred violently, which can improve the overall mixing and stirring efficiency of the device.

[0045] By setting the upper stirring mechanism 6, when the lower stirring mechanism 3 assists in mixing and stirring during use of the equipment, the third motor 61 can be started to run, and the transmission gear 62 can be driven to rotate by the operation of the third motor 61, and the transmission gears 62 are meshed and connected with each other, so that the three sets of rotating shafts 63 can be synchronously driven to rotate. Due to the meshing transmission characteristics of the transmission gear 62, the rotating shafts 63 on both sides and the rotating shaft 63 in the middle rotate in opposite directions, and the stirring plate 64 is tilted. As the stirring plate 64 rotates, it can assist in driving the material to roll up and down. When the stirring plate 64 in the middle stirs upward, the stirring plates 64 on both sides move in the opposite direction to stir the material downward, so that the material can be stirred and mixed up and down inside the mixing box 2, so that the material can be mixed and stirred more evenly. During the stirring and mixing, the bottom is stirred horizontally by the auger 32, which can promote the material to be stirred and mixed more evenly left and right and up and down. Compared with the stirring design of a single group of mixing blades in the existing equipment, it can be seen that the overall stirring and mixing efficiency of the equipment is more efficient and uniform.

[0046] By arranging the lifting mechanism 4 and the discharging mechanism 7, during the use of the equipment, when the stirring and mixing is completed, the first motor 31 can be started to drive the auger 32 to move the raw materials toward the middle of the mixing box 2, and at this time, the electric push rod 73 can be started to run, and the sealing plate 74 can be pulled out from the inside of the reserved groove 75 by the electric push rod 73, and the connection of the discharge pipe 71 can be opened. The connecting groove of the discharge pipe 71 is opened, and the material is driven by the auger 32 to flow toward the discharge pipe 71, and then the material can be quickly discharged through the discharge hopper. When the discharge hopper does not need to be sealed, the sealing plate 74 can be pushed by starting the electric push rod 73 to insert the sealing discharge pipe 71 inside the reserved groove 75, so that the whole device can quickly discharge the material, which is convenient for the operation and use of the equipment. At the same time, when the equipment needs to be inspected, cleaned and maintained, the second motor 42 can be started to run, which is convenient for The second motor 42 can be used to drive the screw rod 43 to drive the slide bar 44 to slide up and down inside the side rail 41. The upward sliding of the slide bar 44 can push the sealing cover 5 to move upward. The upward displacement of the sealing cover 5 can withdraw the upper stirring mechanism 6 from the interior of the mixing box 2 as a whole. At the same time, the mixing box 2 can also be opened, which is convenient for cleaning, inspection and maintenance of the overall internal structure of the device. In use, by driving the sealing cover 5 to move up and down, the scratch frame 10 can be driven up and down by the connecting rod 9 to scrape the material on the inner wall of the mixing box 2. At the same time, the outer side of the auger 32 fits with the arc surface at the bottom of the mixing box, which can scrape the material at the bottom of the mixing box 2, so that the equipment can scratch the inside of the mixing box 2 during use, avoid the adhesion of materials inside the mixing box 2, improve the uniformity of material mixing and the uniformity of discharge, and facilitate the use of the equipment.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
