DETAILED DESCRIPTION

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0033] Embodiment 1

[0034] like Figure 1 and Figure 2As shown, a raw material drying device for producing plastic products includes a bracket 1, a transmission component 2 is fixedly connected to the left side of the upper end of the bracket 1, a drying component 6 is fixedly connected to the inner surface of the transmission component 2, a vibration component 5 is fixedly connected to the right end of the drying component 6, a containing component 3 is fixedly connected to the right end of the vibration component 5, a feeding component 4 is fixedly connected to the right end of the containing component 3, and a discharging component 7 is fixedly connected to the lower side of the front end of the containing component 3.

[0035] First, the device transmission component 2 is started, so that the device transmission component 2 drives the device drying component 6 to rotate, and then the internal heating device is used to preheat the internal components of the device drying component 6, and further, the plastic raw materials required for drying are added to the device feeding component 4. After adding, the internal components of the feeding component 4 are controlled, so that the internal structure of the device feeding component 4 can control the feeding of the plastic raw materials required for drying, so as to facilitate the operator to quantitatively deliver the plastic raw materials, and further allow the plastic raw materials to enter the inner cavity of the device containing component 3 and then flow into the device drying component 6 for drying. After the device drying component 6 dries the plastic raw materials, the device drying component 6 will put the processed plastic raw materials into the bottom of the inner cavity of the device containing component 3 for storage, so as to facilitate the operator to open the device discharge component 7 and collect the dried plastic raw materials;

[0036] In order to achieve the above-mentioned purpose of quantitatively feeding the plastic raw materials;

[0037] For details, please refer to Figure 8 and Fig. 9 The feeding assembly 4 includes a discharge hopper 41, the left end of which is fixedly connected to the middle part of the upper side of the right end of the shell 31, and the left part of the inner cavity of the discharge hopper 41 is fixedly connected to two symmetrically arranged guide plates 42, and the outer surfaces of the two guide plates 42 are slidably connected with a limiting assembly 43, and the limiting assembly 43 includes a limiting plate 431, and the middle part of the inner cavity of the limiting plate 431 is rotatably connected with a rotating handle 434, and the left side of the outer surface of the rotating handle 434 is fixedly connected with a rotating block 433, and the front and rear ends of the rotating block 433 are tightly attached to the sliding plate 432, and the two sliding plates 432 are close to each other.

[0038] As can be seen from the above, after the operator puts the plastic raw materials to be dried into the inner cavity of the device hopper 41, the operator can then rotate the device handle 434 to rotate the device rotating block 433 fixedly connected to its left end, and then when the device rotating block 433 rotates, by squeezing the ends of the two device sliding plates 432 that are close to each other, the two sliding plates 432 can be moved to the ends away from each other, and then press against the ends of the two device guide plates 42 that are close to each other, thereby limiting the position, and further through quantitative feeding, it can be ensured that the amount of plastic raw materials entering the inner cavity of the drying component 6 each time is constant, which helps to maintain the stability of parameters such as temperature and humidity during the drying process, and thus ensure the uniformity and consistency of the drying effect, thereby greatly improving the quality of plastic products and reducing product defects or performance problems caused by uneven drying.

[0039] Embodiment 2

[0040] This embodiment, based on the first embodiment, realizes the purpose of drying the plastic raw material while turning and storing it;

[0041] For further information, please refer to Figure 3 , Figure 4 , Figure 5 and Figure 6The transmission assembly 2 includes two ears 21, the inner surfaces of the two ears 21 are rotatably connected to the limit rod 22, the left rear part of the bracket 1 is fixedly connected to two ears 24, the ends of the two ears 24 close to each other are rotatably connected to the support plate 23, the upper end of the support plate 23 is fixedly connected to the motor 25, the output end of the motor 25 is rotatably connected to the housing 27 through the coupling and the transmission rod, the right end of the transmission rod is fixedly connected to the transmission wheel 26, the left end of the outer surface of the drying assembly 6 is fixedly connected to the transmission wheel 29, the outer surface of the transmission wheel 29 The surface is connected to the outer surface of the transmission wheel 1 26 by winding with a conveyor belt 28. The drying component 6 includes a power rod 61. The left end of the outer surface of the power rod 61 is fixedly connected to the inner surface of the transmission wheel 29. The outer surface of the power rod 61 is rotatably connected to a rotating component 62 on the side close to the transmission wheel 29. The right end of the rotating component 62 is fixedly connected to a material turning component 63. The middle part of the outer surface of the power rod 61 is fixedly connected to two groups of symmetrically arranged blades 65. The right end of the material turning component 63 is fixedly connected to a fixed plate 64. The rotating component 62 includes a sun gear 622 The inner surface of the sun gear 622 is fixedly connected to the left side of the outer surface of the power rod 61, and the outer surface of the power rod 61 is rotatably connected to the outer shell 2 621. The outer surface of the sun gear 622 is meshed with four planetary gears 623 in an annular array. The turning component 63 includes a scroll tube 631, and the inner cavity of the scroll tube 631 is fixedly connected to a plurality of turning blocks 632. The inner cavity of the scroll tube 631 is provided with two groups of matching grooves 633 that match the blades 65. The accommodating component 3 includes a shell 31, and the bottom wall of the inner cavity of the shell 31 is fixedly connected to two guides arranged in a mirror image. Toward block 32, a discharge pipe 33 is fixedly connected to the right wall of the inner cavity of shell 31, and the inner cavity of discharge pipe 33 is communicated with the inner cavity of turning assembly 63, four support columns 34 are fixedly connected to the right wall of the inner cavity of shell 31, and the left ends of four support columns 34 are commonly fixedly connected with a fixing ring 35, and the left part of the outer surface of fixing ring 35 is rotatably connected with fixing plate 64, and discharge assembly 7 includes two guide rods 71, and the rear ends of the two guide rods 71 ​​are fixedly connected with the lower side of the middle part of the front end of shell 31, and the ends of the two guide rods 71 ​​close to each other are commonly slidably connected with discharge plate 72;

[0042] As can be seen from the above, when the operator starts the equipment, the output end of the device motor 25 rotates, and then the transmission rod matched with the coupling will drive the device transmission wheel 1 26 to rotate, thereby driving the device transmission belt 28. When the device transmission belt 28 rotates, it will drive the device transmission wheel 29 fixedly connected to the left end of the device power rod 61 to rotate. Then, while the device power rod 61 is rotating, it will drive the device sun gear 622 fixed on the left side of the power rod 61 to rotate. Further, when the device sun gear 622 rotates, it will mesh with the device planetary gear 623 to make the device housing 2 621 rotate. When the device housing 2 621 rotates, it will drive the device fixedly connected to the housing 2 621 The material turning assembly 63 at the right end rotates, so that when the plastic raw material enters the inside of the device material turning assembly 63, the several material turning blocks 632 fixedly connected therein will screen the plastic raw material, and further screen out the wet and agglomerated raw material, and then the two groups of device blades 65 fixedly connected to the middle of the outer surface of the device power rod 61 will break it up, so that the material is dried again. Furthermore, the plastic raw material screened by the device material turning block 632 will be conducted and dried by the device vortex tube 631, so that the dried plastic raw material will be sprinkled into the bottom wall of the inner cavity of the device shell 31, and then the dried plastic raw material will be guided by the device guide blocks 32 arranged in a mirror image on both sides, so as to achieve the purpose of drying and turning the raw material while storing the processed material;

[0043] In addition, by providing four device support columns 34 at the right end of the device fixing ring 35 and fixedly connecting them to the left wall of the inner cavity of the device shell 31, the device fixing plate 64 can be made more stable when rotating.

[0044] It should be further explained that: a heating plate is provided at one end of the device housing 621 and the device fixing plate 64 close to each other, a temperature control sensor is installed in the middle of the upper wall of the inner cavity of the device housing 31, and a filter hole is opened in the middle of the rear end of the housing 31, so that when the plastic raw material is dried, the harmful gas generated by the plastic raw material will be adsorbed and filtered by the activated carbon inside the filter hole and discharged. Furthermore, the temperature control sensor at the upper end of the device housing 31 can be connected to the operator's mobile phone in the form of Bluetooth, so that the operator can grasp the drying temperature of the plastic raw material in real time;

[0045] In addition, it should be noted that the temperature control sensor and the heating plate are both conventional designs in the prior art, and the working principle of the heating plate is to convert electrical energy into thermal energy and use conduction and other methods to heat the object;

[0046] The working principle of the temperature control sensor is to use the thermistor effect. A thermistor is a resistor whose resistance value changes with temperature. When the ambient temperature changes, the resistance value of the thermistor will increase or decrease accordingly, so the temperature can be inferred by measuring the resistance value.

[0047] Embodiment 3

[0048] This embodiment is based on the second embodiment, in which the drying component 6 of the device is vibrated during the drying process of the plastic raw material, thereby avoiding uneven drying of the plastic raw material.

[0050] It can be further known from the above that when the device fixing plate 64 is rotating, the six device fixing blocks 55 fixedly connected to the right end thereof will rotate along with the rotation of the device fixing plate 64, and then when the device fixing block 55 is rotating, the six device silicone wheels 53 are squeezed through the slope, so that the device fixing tube 2 52 slides to the inner cavity of the device fixing tube 1 51, and when the device fixing block 55 continues to rotate, the device silicone wheel 53 will be stretched out quickly under the elastic force of the device spring 2 54 itself, so as to impact the fixing plate 64, thereby preventing the plastic raw material in the inner cavity of the device turning component 63 from getting stuck, thereby improving the drying rate;

[0051] In addition, any circuit connection in this solution is a conventional design in the prior art, and this solution will not be elaborated in detail.
