Description

Technical Field

[0001] The invention relates to the technical field of plastic products, in particular to a granular plastic product packaging device. Background Art

[0002] Plastic products are a general term for daily necessities and industrial products made of plastic as the main raw material, including products made from injection molding, vacuum forming and other processes using plastic as the raw material. Plastic is a type of synthetic polymer material with plasticity. Together with synthetic rubber and synthetic fiber, it forms the three major synthetic materials that are indispensable in daily life. Specifically, plastic is a material with natural or synthetic resin as the main component, with various additives added. It can be molded into a certain shape under certain temperature and pressure conditions and keep its shape unchanged at room temperature.

[0003] However, in the production and processing of granular plastic products, the packaging process is crucial. At present, when granular plastic products are packaged, they are generally packaged through a guide barrel and then fixed with a packaging bag at the bottom, but this traditional method has some problems. On the one hand, there may be impurities and dust in the plastic products. If these impurities are not effectively removed, the quality of the plastic products after packaging will be affected; on the other hand, some of the plastic products may be too small. If they are not screened, the overall packaging quality will be affected; moreover, when replacing the packaging bags, the control mechanism in the traditional device may cause plastic products to be clamped, and the material may be discharged too quickly, which may easily cause waste of granular plastic products and increase the workload of later processing. In addition, blockage is prone to occur during the screening process, which affects the screening efficiency and quality, and it is difficult to clear the blockage, which increases the maintenance cost and causes economic losses.

[0004] In view of this, we propose a granular plastic product packaging device. Summary of the invention

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figure 1 and Figure 2 As shown, the purpose of this embodiment is to provide a granular plastic product packaging device, including a housing 10, a support column 20 and a top plate 21, the housing 10 is provided with a filter plate 13 capable of filtering impurities and dust, the filter plate 13 is inclined, the opening below the housing 10 is provided with a waste pipe 12 capable of discharging impurities and dust, the opening on the side of the housing 10 is provided with a second lower hopper 11, and a control member 14 capable of controlling the discharge of materials is provided below the second lower hopper 11;

[0034] An elastic ring 23 is provided on the lower surface of the top plate 21, a feed pipe 22 is provided on one side above the top plate 21, an auxiliary component 40 is provided in the middle of the lower surface of the top plate 21, and a screening component 30 is provided below the elastic ring 23;

[0035] The auxiliary part 40 is used to deform the elastic ring 23 and rotate the auxiliary screening part 30 to screen the granular plastic products. At the same time, the screening part 30 can be cleaned to prevent the granular plastic products from clogging the screening part 30. The auxiliary part 40 can also discharge the screened granular plastic products.

[0036] When the filter plate 13 is tilted, the inclination of the filter plate 13 allows the overly small granular plastic products to be discharged. In the process of discharging, it is inevitable that the packaging bags need to be replaced. In order to prevent the waste of granular plastic products or the need for later processing, the workload of granular plastic product packaging is increased. Therefore, according to Figure 2 and Figure 8 As shown, the specific structure of the control member 14 is disclosed. The control member 14 at least includes a mounting shell 141. A multi-stage cylinder 142 is arranged inside the mounting shell 141. The piston rod of the multi-stage cylinder 142 is provided with a control plate 143.

[0037] When it is necessary to replace the packaging bag, the multi-stage cylinder 142 is powered on to make it work. The control board 143 is moved upward by the piston rod of the multi-stage cylinder 142 to block the second discharge hopper 11. At this time, the packaging bag can be replaced. After completion, the control board 143 is moved downward by the piston rod of the multi-stage cylinder 142 being reset, so that the too small granular plastic products can be discharged. Moreover, by blocking from bottom to top through the control part 14, the damage to the too small granular plastic products can be reduced, the quality of the granular plastic product packaging is improved, and the working efficiency of the packaging device is improved, thereby improving the reliability of the packaging device.

[0038] In order to improve the quality of granular plastic products packaging, granular plastic products are screened and filtered during the packaging process. Figure 1 , Figure 2 , Figure 3 and Figure 5 It can be known that the specific structure of the screening element 30 is disclosed, and the screening element 30 at least includes a mounting ring 32, a screening net 34 is placed inside the mounting ring 32, a connecting ring 31 is arranged below the elastic platform ring 23, and a plurality of fixing parts 33 for plugging and matching with the connecting ring 31 are arranged on the outer wall of the mounting ring 32, and a first lower hopper 35 is arranged on the side of the connecting ring 31 away from the feeding pipe 22.

[0039] Open the fixing part 33 to separate the mounting ring 32 from the connecting ring 31. At this time, the screening net 34 to be used can be placed inside the mounting ring 32, and then the mounting ring 32 is fitted to the connecting ring 31, and the fixing part 33 is used to fix the position of the mounting ring 32 to prevent the auxiliary part 40 from causing the mounting ring 32 to be separated from the connecting ring 31 during operation. In addition, the mesh size of the above-mentioned screening net 34 can be selected according to the size of the granular plastic products to be screened, and the screening particle size of the granular plastic products can be controlled to ensure that the quality of the products after packaging is more uniform. At the same time, the convenient installation and disassembly method also facilitates the operator to make quick adjustments according to different production needs, improves the adaptability and flexibility of production, and while improving production efficiency, it also helps to reduce the subsequent processing costs caused by unstable product quality, thereby improving the economic benefits of the packaging device during use.

[0040] according to Figure 5 and Figure 6 As shown, the specific structure of the fixing member 33 is further disclosed. An electric telescopic rod 331 is arranged inside the outer wall of the mounting ring 32. The piston rod of the electric telescopic rod 331 is provided with a fixing plate 332. A fixing block 333 is arranged at the upper end of the fixing plate 332 close to the electric telescopic rod 331. A fixing groove 334 for plugging and matching with the fixing block 333 is opened on the outer wall of the connecting ring 31.

[0041] The electric telescopic rod 331 is connected to a power source to make it work, and the fixing plate 332 is moved away from the mounting ring 32 by the pushing work of the piston rod of the electric telescopic rod 331. At this time, the mounting ring 32 is fitted to the connecting ring 31, and the fixing block 333 is inserted into the interior of the fixing groove 334 by the work of resetting the piston rod of the electric telescopic rod 331 so that the screening net 34 can be installed. This is not only convenient and efficient to operate, but also saves time in installing and disassembling the screening net 34 and improves production efficiency, and also improves the firmness and reliability of the installation. During the operation of the auxiliary part 40, the mounting ring 32 can be effectively prevented from separating from the connecting ring 31, thereby ensuring the stability of the screening process and improving the quality of the screening. In addition, the flexibility of replacing the screening net 34 is improved, and the adaptability and versatility of the packaging device are further enhanced.

[0042] Considering that while the elastic ring 23 is deforming, the auxiliary member 40 assists in unloading the granular plastic products after screening, and the first unloading hopper 35 is close to one end of the elastic ring 23, it is inevitable that the granular plastic products will fall, affecting the quality of screening. Therefore, according to Figure 3 and Fig. 9It can be seen that an elastic plate 36 is provided at the upper end of the first lower hopper 35 on the side close to the connecting ring 31, and the end of the elastic plate 36 away from the first lower hopper 35 is fixedly connected to the elastic ring 23. On the one hand, it can play a good sealing role. When the elastic ring 23 is deformed, the elastic plate 36 is deformed accordingly, and fits tightly at the connection between the elastic ring 23 and the first lower hopper 35, effectively discharging the granular plastic products to prevent waste. On the other hand, it also avoids the poor screening caused by the poor sealing, which causes the granular plastic products after screening to enter the interior of the shell 10, thereby improving the quality of the granular plastic product packaging.

[0043] In order to achieve the purpose of indirect material discharge during the screening of granular plastic products, it is convenient to replace the packaging bags without affecting the normal screening of granular plastic products. Therefore, according to Figure 2 and Figure 4 It can be seen that the specific structure of the auxiliary component 40 is disclosed. A hydraulic cylinder 41 is arranged in the middle of the lower surface of the top plate 21. The piston rod of the hydraulic cylinder 41 is provided with a connecting shell 42. A rotating shaft 43 is rotatably connected below the connecting shell 42. A cleaning brush 44 is arranged at the bottom of the rotating shaft 43.

[0044] The hydraulic cylinder 41 and the motor are powered on to make them work. The cleaning brush 44 is moved downward by the piston rod of the hydraulic cylinder 41, so that the cleaning brush 44 presses one side of the screening net 34, so that the screening net 34 is tilted, and the rotating shaft 43 is driven to rotate by the rotation of the motor output shaft, so that the cleaning brush 44 rotates on the upper surface of the screening net 34, and at the same time, the elastic ring 23 is deformed to screen the granular plastic products, and the bristles of the cleaning brush 44 clean the holes of the screening net 34. Washing can prevent dust from accumulating on the upper surface of the screening net 34 on the one hand, and can prevent granular plastic products from clogging the screening net 34 on the other hand, thereby improving the service life of the screening net 34. In addition, when the cleaning brush 44 rotates to the opening on one side of the elastic ring 23, the granular plastic products after screening can be unloaded, and when the cleaning brush 44 rotates to the opening away from the side of the elastic ring 23, the granular plastic products on the screening net 34 can be broken up, thereby improving the screening quality, thereby improving the practicability of the packaging device.

[0045] The speed of the above-mentioned motor can be reasonably adjusted according to the size, hardness, shape and smoothness of the granular plastic products. If the speed is too fast, the cleaning brush 44 may exert too much force on the screening net 34 and the granular plastic products, which may easily damage the screening net 34 and the plastic products. At the same time, the particles may splash, affecting the screening effect and the safety of the working environment. Moreover, too fast a speed may cause the elastic ring 23 to deform too violently, affecting its service life and stability; if the speed is too slow, the cleaning effect of the cleaning brush 44 on the screening net 34 and the breaking up of the plastic products will be weakened, and it will not be possible to prevent blockage and improve the screening quality in time, and the feeding efficiency will also be reduced; controlling the speed of the motor can better balance the effect of the cleaning brush 44, the impact on the screening net 34 and plastic products, and the feeding efficiency, thereby achieving the above-mentioned good effect.

[0046] While the cleaning brush 44 is rotating, in order to better balance the cleaning effect and the influence on the screening efficiency of the granular plastic products and the deformation amplitude of the elastic ring 23, according to Figure 2 and Figure 4 It can be seen that the cleaning brush 44 is in a "V" shape and is inclined. The "V"-shaped cleaning brush 44 can, on the one hand, effectively prevent the cleaning brush 44 from being too large and affecting the screening efficiency of granular plastic products; if the cleaning brush 44 is too large, it may hinder the normal flow of plastic products during rotation, reducing the screening speed and efficiency; on the other hand, it can also prevent the cleaning brush 44 from being too small and affecting the deformation amplitude of the elastic ring 23. If the cleaning brush 44 is too small, it may not be able to apply sufficient pressure to the screening net 34, resulting in insufficient deformation of the elastic ring 23, affecting the screening effect and the smoothness of material discharge. In addition, the "V"-shaped design does not affect the cleaning brush's work of discharging granular plastic products while applying lateral pressure, thereby improving the practicability of the packaging device.

[0047] In summary, the working principle of the present invention is as follows: first, the hydraulic cylinder 41 and the motor are powered on to make them work, and the cleaning brush 44 is moved downward by the pushing work of the piston rod of the hydraulic cylinder 41, so that the cleaning brush 44 presses one side of the screening net 34, so that the screening net 34 is inclined, and the rotating shaft 43 is driven to rotate by the rotation of the motor output shaft, so that the cleaning brush 44 rotates on the upper surface of the screening net 34, and at the same time, the elastic ring 23 is driven to deform. At this time, the granular plastic products flow into the inside of the elastic ring 23 through the feed pipe 22, so that the shaking screening net 34 filters and screens the granular plastic products, and the granular plastic products remaining above the screening net 34 are filtered and screened by the granular plastic products. When the cleaning brush 44 rotates to the opening on one side of the elastic ring 23, the granular plastic products remaining on the top of the screening net 34 can flow to the first lower hopper 35 for unloading, and the granular plastic products, debris and dust that are too small flow to the bottom of the screening net 34. After that, the debris and dust are filtered by the filter plate 13 and flow to the inside of the waste pipe 12 to be discharged. The granular plastic products remaining on the top of the filter plate 13 flow to the second lower hopper 11 in an inclined shape through the filter plate 13. At this time, the control plate 143 is moved downward by resetting the piston rod of the multi-stage cylinder 142, so that the granular plastic products that are too small can be unloaded, and the use of the packaging device can be completed.

[0048] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments.
