Description

Technical Field

[0001] The present application relates to the technical field of plastic masterbatch processing and production, and in particular to a pretreatment device and process for drying plastic masterbatch. Background Art

[0002] Plastic masterbatch is one of the raw materials for various new plastic material products, so the quality of plastic masterbatch seriously affects the quality of the finished product. In the production of plastic masterbatch, the drying and screening of plastic masterbatch is the most critical process.

[0003] In the related art, the raw materials of plastic masterbatch need to be dried during processing to keep the raw materials dry. Before the plastic masterbatch is dried, the dust in the workshop air is easily mixed into the raw materials of the plastic masterbatch during the processing and molding of the plastic masterbatch in the workshop. This requires that these dust impurities be removed from the raw materials of the plastic masterbatch before the plastic masterbatch is dried. The traditional treatment method is to separate the removal of impurities and the drying treatment into two processes: first remove the impurities, then dry. This treatment method is relatively cumbersome, which leads to low efficiency of the overall drying process of the plastic masterbatch, which is not conducive to the daily processing and production of plastic masterbatch. Summary of the invention

[0004] The present application provides a pretreatment device and process for drying plastic masterbatches, the purpose of which is to simultaneously remove impurities and dry the plastic masterbatches during processing and production, thereby optimizing the process of daily processing and production of plastic masterbatches, which is beneficial to significantly improve the efficiency of daily processing and production of plastic masterbatches.

[0005] The present application provides a pretreatment device and process for drying plastic masterbatch, which adopts the following technical solution:

[0006] A pretreatment device for drying plastic masterbatch, comprising a chassis, wherein a plurality of guide plates for conveying plastic masterbatch are arranged obliquely from top to bottom inside the chassis, the ends of the plurality of guide plates are staggered so that the plurality of guide plates cooperate with each other to form a channel for the flow of plastic masterbatch, and a feed inlet and a feed outlet are respectively provided at the upper and lower ends of the chassis, the feed inlet is located at the top of the chassis and is directly above the high end of the uppermost guide plate, and the feed outlet is located at the bottom of the chassis and is directly below the low end of the lowermost guide plate;

[0007] A plurality of hot air blowers and filter plates are installed on the inner walls on both sides of the left and right sides of the chassis, an air outlet pipe for discharging hot air is installed in the hot air blower, a filter is installed on the filter plate, the plurality of hot air blowers and filter plates correspond one to one with the plurality of material guide plates, and the corresponding hot air blower is located at the low end of the corresponding material guide plate, and the corresponding filter plate is located directly above the high end of the corresponding material guide plate, and the air outlet angle of the hot air blower remains parallel to the material guide plate.

[0008] By adopting the above technical solution, the plastic masterbatch is dried by the hot air blown by the corresponding hot air blower during the downward flow on the guide plate. At the same time, the hot air blows the dust between the plastic masterbatch upward, adsorbed on the filter plate or falling into the impurity removal box. These plastic masterbatch will be dried and impurity-removed multiple times in the process of flowing from the top guide plate to the bottom guide plate, and each drying and impurity removal is carried out synchronously. This makes it possible for the plastic masterbatch added from the feed inlet to be discharged from the discharge port, and multiple levels of drying and impurity removal will be carried out synchronously.

[0009] This setting method can simultaneously remove impurities and dry the plastic masterbatch during processing and production, thereby optimizing the process of daily processing and production of plastic masterbatch, which is beneficial to significantly improve the efficiency of daily processing and production of plastic masterbatch.

[0010] Preferably, the material guide plate is rotatably mounted in the chassis.

[0011] By adopting the above technical solution, the purpose of doing so is to be able to adjust the inclination angle of the guide plate. When the number of plastic masterbatches that need to be dried is large, the guide plate is turned upward to make its inclination angle gentler, so that the time for the plastic masterbatches to flow on the guide plate will be longer, which can effectively extend the drying time of the plastic masterbatch by the hot air blower corresponding to the guide plate, thereby improving the drying effect of the plastic masterbatch. At the same time, the more plastic masterbatches there are, the more impurities there are in them. Adjusting the guide plate to be gentle can extend the time for the hot air blower to remove impurities, thereby improving the effect of removing impurities.

[0012] Preferably, the guide plate drives the corresponding hot air blower to rise and fall while rotating.

[0013] By adopting the above technical solution, the purpose is to always keep the air outlet of the hot air fan at the lower end of the material guide plate, and effectively avoid the air outlet of the hot air fan being separated from the lower end of the material guide plate when the material guide plate rotates upward, thereby causing the hot air fan to be unable to blow air to the material guide plate.

[0014] Preferably, the hot air blower drives the blades of the air outlet duct to rotate while rising and falling.

[0015] By adopting the above technical solution, the purpose of doing so is to adjust the air outlet angle of the hot air blower by driving the fan blades up and down, so that the air outlet angle of the hot air blower can always remain parallel to the guide plate during the rotation of the corresponding guide plate and the lifting of the hot air blower. The purpose of keeping the air outlet angle of the hot air blower parallel to the corresponding guide plate is to avoid the formation of an angle between the air outlet angle of the hot air blower and the guide plate, so that the hot air blown out by the hot air blower can fully contact the plastic masterbatch on the guide plate, effectively enhancing the drying effect of the plastic masterbatch. At the same time, if there is an angle between the hot air blown out by the hot air blower and the guide plate, the hot air will first blow the impurities between the plastic masterbatch onto the guide plate, and then blow these impurities upward. By keeping the air outlet angle of the hot air blower parallel to the corresponding guide plate, the hot air can directly blow these impurities upward, thereby effectively improving the effect of the hot air blower on removing impurities between the plastic masterbatch.

[0016] Preferably, a plurality of groups of first adjustment components are provided on the back of the chassis, and the plurality of groups of the first adjustment components correspond one-to-one to the plurality of groups of the material guide plates, and the first adjustment components are used to adjust the inclination angle of the material guide plates;

[0017] The first adjustment component comprises an adjustment box, a rotating handle, a rotating rod, a first gear and a first rack, the adjustment box is installed on the back of the chassis, the rotating handle is inserted on the adjustment box in a direction perpendicular to the adjustment box, one end of the rotating handle extends out of the adjustment box, the rotating rod is coaxially and integrally connected to the other end of the rotating handle in a horizontal direction, the first gear is vertically arranged, the end of the rotating rod away from the rotating handle is coaxially and integrally connected to the first gear, the first rack is vertically arranged, and the side wall of the first rack is meshed and connected with the first gear, the first rack is connected to the side wall of the guide plate through a movable rod, and the left and right sides of the high end of the guide plate are both hingedly connected to the inner wall of the chassis;

[0018] A first waist-shaped hole is horizontally penetrated through the bottom of the first rack, and a second waist-shaped hole is penetrated through the back of the chassis. The second waist-shaped hole is in a curved arc shape. The movable rod is horizontally arranged, and one end of the movable rod is integrally connected to the side wall of the guide plate, and the other end of the movable rod passes through the second waist-shaped hole and extends into the first waist-shaped hole.

[0019] By adopting the above technical solution, when adjusting the inclination angle of the guide plate, the handle is rotated, and the handle drives the rotating rod to rotate, and the first gear is driven to rotate synchronously. During the rotation process, the first gear meshes with the first rack, and then drives the first rack to rise and fall in the vertical direction through the first gear. During the vertical lifting process, the first rack drives the guide plate to rotate through the corresponding movable rod.

[0020] During the rotation and adjustment of the guide plate, the overall movement trajectory of the guide plate is arc-shaped. In order to effectively avoid interference between the movement trajectory of the guide plate and the first rack during the rotation and adjustment process, the first waist-shaped hole and the second waist-shaped hole are used to keep the movement trajectory of the movable rod equal to the movement trajectory of the guide plate, and then the movement interference between the guide plate and the first rack is offset by the movable rod, effectively ensuring that the guide plate can be smoothly rotated and adjusted under the drive of the first rack.

[0021] Preferably, the lower end of the guide plate is connected to the inner wall of the hot air blower through two left and right first linkage rods, and the side walls of the two first linkage rods are provided with corresponding third waist-shaped holes, and movable blocks are inserted into the third waist-shaped holes. The side walls of the movable blocks are integrally formed with movable plates, and the movable plates are installed on the hot air blower.

[0022] By adopting the above technical solution, the guide plate drives the hot air blower to rise and fall through the two first linkage rods during the rotation process. At the same time, the movable block moves in the corresponding third waist-shaped hole during the rotation process of the guide plate, and drives the hot air blower to rise and fall through the movable plate, effectively avoiding motion interference between the rotation of the guide plate and the lifting process of the hot air blower, so that the air outlet of the hot air blower can always correspond to the low end of the guide plate.

[0023] Preferably, a second adjusting component is provided inside the hot air blower, and during the lifting and lowering process of the hot air blower, the second adjusting component is used to adjust the air outlet angle of the air outlet pipe;

[0024] The second adjusting component comprises a second rack, a second gear, a driving gear, a driven gear, a screw, a lifting plate and a second linkage rod, the second rack is vertically fixed in the hot air blower, the second gear is connected to the bottom of the air outlet pipe through a corresponding connecting rod, and the second gear is meshed with the second rack, the driving gear and the driven gear are both located at the bottom of the air outlet pipe, the driving gear is vertically arranged, the driven gear is horizontally arranged, the driving gear and the second gear are coaxially connected, the driven gear is meshed with the driving gear, the screw is vertically arranged in the air outlet pipe, and the bottom of the screw extends downwardly out of the air outlet pipe, the driven gear is integrally sleeved on the circumference of the screw, the lifting plate is sleeved on the screw and cooperates with the screw thread, the second linkage rod is vertically arranged, the side wall of the lifting plate is connected to the top of the second linkage rod, the side wall of the second linkage rod is connected to the fan blade on the air outlet pipe, and the left and right ends of the fan blade are hingedly mounted on the air outlet pipe;

[0025] A fourth waist-shaped hole is installed between the lifting plate and the top of the second linkage rod, and the top of the second linkage rod is also integrally connected with the movable block, and the movable block is located in the fourth waist-shaped hole.

[0026] By adopting the above technical solution, when the hot air blower is specifically lifted or lowered, the hot air blower drives the second rack to lift or lower, and the second rack meshes with the second gear at the bottom of the air outlet pipe while being lifted or lowered. The second gear drives the driving gear to rotate during the rotation process, and drives the driven gear to rotate through the driving gear. The screw rotates under the drive of the driven gear, and drives the lifting plate to lift or lower during the rotation process. While the lifting or lowering plate is being lifted or lowered, it drives the second linkage rod to lift or lower, and then drives the fan blades on the air outlet pipe to rotate through the lifting or lowering of the second linkage rod, thereby adjusting the air outlet angle of the fan blades of the air outlet pipe, so that the air outlet angle of the hot air blower can always remain parallel to the inclination angle of the guide plate.

[0027] When the fan blade is rotating, the movable block slides in the fourth waist-shaped hole, and then the fourth waist-shaped hole is used to effectively avoid the fan blade from interfering with the lifting and lowering of the lifting plate during the rotation process.

[0028] Preferably, a material control plate is additionally provided on the top of the material guide plate located at the top of the chassis, and a through hole for the flow of plastic masterbatch is formed between the material control plate and the material guide plate, and the material guide plate drives the material control plate to rotate during the rotation process;

[0029] The left and right sides of the first rack are both tooth-shaped, and the side of the first rack away from the first gear is meshed and connected with a third gear. A corresponding rotating rod is also provided between the third gear and the top of the material control plate, and the rotating rod is coaxially connected to the third gear.

[0030] By adopting the above technical solution, the first rack drives the guide plate to rotate during the lifting process, and the first rack meshes with the third gear. In this state, the third gear rotates and drives the material control plate to rotate, and then the number of plastic masterbatches is controlled by the material control plate. The number of plastic masterbatches on the guide plate is controlled by the material control plate. When the number of plastic masterbatches is large, the inclination angle of the guide plate is adjusted to be gentle, and the material control plate is rotated in the direction close to the guide plate. In this state, the opening between the material control plate and the guide plate becomes smaller, thereby reducing the number of plastic masterbatches passing through the opening at one time, which can further improve the effect of the hot air blower on drying and removing impurities from the plastic masterbatch. At the same time, in order to effectively prevent the material control plate from hindering the impurity removal process of the hot air blower, a filter is also installed on the side wall of the material control plate.

[0031] Preferably, a debris removal box is detachably mounted on both the left and right sides of the chassis, and the debris removal box is connected to the filter plate located on the same side.

[0032] By adopting the above technical solution, the impurity removal box is fastened to the chassis by fastening bolts, which makes it easy to remove the impurity removal box from the chassis to clean the impurities in the impurity removal box, and also makes it easy to clean the filter plate.

[0033] A pretreatment process for drying plastic masterbatch, using the above-mentioned pretreatment equipment for drying plastic masterbatch, comprises the following steps:

[0034] S1. Add the plastic masterbatch into the chassis from the inlet at the top of the chassis. After entering the chassis, the plastic masterbatch first falls onto the top guide plate and is dried and impurity removed by the corresponding hot air blower;

[0035] S2, the plastic masterbatch gradually flows to the bottom guide plate, and after multi-stage drying and impurity removal, it is finally discharged from the discharge port at the bottom of the chassis;

[0036] S3, adjusting the inclination of the guide plate through the first adjustment component, the guide plate drives the corresponding hot air blower to rise and fall during the adjustment process, and simultaneously drives the fan blades on the hot air blower to rotate, and at the same time, the control plate rotates to control the amount of plastic masterbatch;

[0037] S4. Remove the debris removal boxes on the left and right sides of the chassis, and clean the impurities and filter plates in the debris removal boxes.

[0038] By adopting the above technical solution, this setting method can simultaneously remove impurities and dry the plastic masterbatch during processing and production, thereby optimizing the process of daily processing and production of plastic masterbatch, which is beneficial to significantly improve the efficiency of daily processing and production of plastic masterbatch.

[0039] In summary, the present application includes at least one of the following beneficial technical effects:

[0040] 1. When the plastic masterbatch flows downward on the guide plate, it is dried by the hot air blown by the corresponding hot air blower. At the same time, the hot air blows the dust between the plastic masterbatch upward, adsorbed on the filter plate or falling into the impurity removal box. These plastic masterbatch will be dried and impurity-removed many times in the process of flowing from the top guide plate to the bottom guide plate, and each drying and impurity removal is carried out synchronously. This makes the plastic masterbatch added from the inlet be dried and impurity-removed at multiple levels when it is discharged from the outlet, and each level of drying and impurity removal is carried out synchronously.

[0041] This setting method can simultaneously remove impurities and dry the plastic masterbatch during processing and production, thereby optimizing the process of daily processing and production of plastic masterbatch, which is beneficial to significantly improve the efficiency of daily processing and production of plastic masterbatch;

[0042] 2. The guide plate is rotatably installed in the chassis. The purpose of this is to be able to adjust the inclination angle of the guide plate. When there are a large number of plastic masterbatches that need to be dried, the guide plate is rotated upward to make its inclination angle gentler, so that the time for the plastic masterbatch to flow on the guide plate will be longer, which can effectively extend the drying time of the plastic masterbatch by the corresponding hot air blower of the guide plate, thereby improving the drying effect of the plastic masterbatch. At the same time, the more plastic masterbatches there are, the more impurities there are in them. Adjusting the guide plate to be gentle can extend the time for the hot air blower to remove impurities and improve the effect of removing impurities;

[0043] 3. When the guide plate rotates, it drives the corresponding hot air blower to rise and fall. The purpose of this is to keep the air outlet of the hot air blower at the lower end of the guide plate at all times, effectively preventing the air outlet of the hot air blower from being separated from the lower end of the guide plate when the guide plate rotates upward, thereby causing the hot air blower to be unable to blow air to the guide plate.

DETAILED DESCRIPTION

[0053] The following is combined with Figure 1 -Attached Figure 8 , further details of this application are given.

[0054] Example:

[0055] The present application embodiment discloses a pretreatment device for drying plastic masterbatch, referring to Figure 1 and Figure 2 , including a rectangular parallelepiped chassis 1, the interior of the chassis 1 is hollow, and a plurality of guide plates 2 for conveying plastic masterbatch are arranged obliquely from top to bottom inside the chassis 1, and the guide plates 2 are rectangular parallelepiped. The ends of these guide plates 2 are staggered from each other so that the plurality of guide plates 2 cooperate with each other to form a channel for the flow of plastic masterbatch. The upper and lower ends of the chassis 1 are respectively provided with a feed inlet 3 and a discharge port 4, the feed inlet 3 is located at the top of the chassis 1, and is directly above the high end of the uppermost guide plate 2, and the discharge port 4 is located at the bottom of the chassis 1, and is directly below the low end of the lowermost guide plate 2.

[0056] Reference Figure 1 and Figure 2 , multiple hot air blowers 5 and filter plates 6 are installed on the inner walls of the left and right sides of the chassis 1. An outlet pipe 7 for hot air is installed in the hot air blower 5, and a filter screen is installed on the filter plate 6. These hot air blowers 5 and filter plates 6 correspond to these material guide plates 2 one by one, and the corresponding hot air blower 5 is located at the low end of the corresponding material guide plate 2, and the corresponding filter plate 6 is located just above the high end of the corresponding material guide plate 2. The air outlet angle of the hot air blower 5 remains parallel to the material guide plate 2. At the same time, the left and right sides of the chassis 1 are fastened with a debris removal box 20 by fastening bolts, and the debris removal box 20 is connected to the filter plate 6 on the same side. The debris removal box 20 is fastened to the chassis 1 by fastening bolts, which is convenient for removing the debris removal box 20 from the chassis 1 to clean the impurities in the debris removal box 20, and it is also convenient for cleaning the filter plate 6.

[0057] Specifically, when processing the plastic masterbatch, the plastic masterbatch is added into the chassis 1 from the feed port 3 at the top of the chassis 1. After entering the chassis 1, the plastic masterbatch first falls onto the uppermost guide plate 2. Since the guide plate 2 is inclined, the plastic masterbatch that falls onto the guide plate 2 flows downward, and gradually flows to the lowermost guide plate 2, and is finally discharged from the discharge port 4 at the bottom of the chassis 1.

[0058] While adding materials into the chassis 1, turn on the hot air blower 5 in the chassis 1. While the plastic masterbatch flows on the guide plate 2, the corresponding hot air blower 5 is located at the low end of the corresponding guide plate 2, and the corresponding filter plate 6 is located just above the high end of the corresponding guide plate 2. While the plastic masterbatch flows downward on the guide plate 2, the hot air from the corresponding hot air blower 5 blows the plastic masterbatch upward. While the hot air blows the plastic masterbatch upward, it blows the dust between the plastic masterbatch upward to the filter plate 6 above the high end of the corresponding guide plate 2. Part of the dust blown upward by the hot air is adsorbed by the filter plate 6, and part of it is carried by the hot air through the filter plate 6 into the corresponding impurity removal box 20.

[0059] When the plastic masterbatch flows downward on the guide plate 2, it is dried by the hot air blown by the corresponding hot air blower 5. At the same time, the hot air blows the dust between the plastic masterbatch upward, adsorbed on the filter plate 6 or falls into the impurity removal box 20. These plastic masterbatch will be dried and impurity-removed multiple times in the process of flowing from the top guide plate 2 to the bottom guide plate 2, and each drying and impurity removal is carried out synchronously. This makes it possible for the plastic masterbatch added from the feed inlet 3 to be discharged from the discharge port 4, and multiple levels of drying and impurity removal will be carried out, and each level of drying and impurity removal is carried out synchronously.

[0060] This setting method can simultaneously remove impurities and dry the plastic masterbatch during processing and production, thereby optimizing the process of daily processing and production of plastic masterbatch, which is beneficial to significantly improve the efficiency of daily processing and production of plastic masterbatch.

[0061] In this embodiment, the number of the guide plates 2 is three. In the actual production process, the number of the guide plates 2 can be adjusted accordingly according to the specific operating conditions.

[0062] Furthermore, each guide plate 2 can rotate in the vertical direction. The purpose of this is to adjust the inclination angle of the guide plate 2. When there are a large number of plastic masterbatches that need to be dried, the guide plate 2 is rotated upward to make its inclination angle gentler, so that the time for the plastic masterbatches to flow on the guide plate 2 will be longer, which can effectively extend the drying time of the hot air blower 5 corresponding to the guide plate 2 for the plastic masterbatches, thereby improving the drying effect of the plastic masterbatches. At the same time, the more plastic masterbatches there are, the more impurities there are in them. Adjusting the guide plate 2 to be gentle can extend the time for the hot air blower 5 to remove impurities, thereby improving the effect of removing impurities.

[0063] Furthermore, when the guide plate 2 rotates in the vertical direction, it can drive the corresponding hot air blower 5 to move up and down in the vertical direction. The purpose of this is to always keep the air outlet of the hot air blower 5 at the lower end of the guide plate 2, and effectively prevent the air outlet of the hot air blower 5 from being separated from the lower end of the guide plate 2 when the guide plate 2 rotates upward, thereby causing the hot air blower 5 to be unable to blow air to the guide plate 2.

[0064] Furthermore, when the hot air blower 5 is lifted and lowered in the vertical direction driven by the corresponding guide plate 2, the blades on the hot air blower 5 can swing up and down as the hot air blower 5 is lifted and lowered. The purpose of this is to adjust the air outlet angle of the hot air blower 5 by driving the blades up and down, so that the air outlet angle of the hot air blower 5 can always remain parallel to the guide plate 2 during the rotation of the corresponding guide plate 2 and the lifting and lowering of the hot air blower 5. The purpose of keeping the air outlet angle of the hot air blower 5 parallel to the corresponding guide plate 2 is to avoid the formation of an angle between the air outlet angle of the hot air blower 5 and the guide plate 2, so that the hot air blown out by the hot air blower 5 can fully contact the plastic masterbatch on the guide plate 2, effectively enhancing the drying effect of the plastic masterbatch. At the same time, if there is an angle between the hot air blown out by the hot air blower 5 and the guide plate 2, the hot air will first blow the impurities between the plastic masterbatch to the guide plate 2, and then blow these impurities upward. By keeping the air outlet angle of the hot air blower 5 parallel to the corresponding material guide plate 2, the hot air can directly blow these impurities upward, thereby effectively improving the effect of the hot air blower 5 on removing impurities between plastic masterbatches.

[0065] Specifically, refer to Figure 1 and Figure 2 A plurality of first adjustment components 8 are provided on the back of the chassis 1 , and these first adjustment components 8 correspond one-to-one to the plurality of guide plates 2 in the chassis 1 , and the first adjustment components 8 are used to adjust the inclination angle of the guide plates 2 .

[0066] Specifically, refer to Figure 1 and Figure 6The first adjustment assembly 8 includes an adjustment box 81, a rotating handle 82, a rotating rod 83, a first gear 84 and a first rack 85. The adjustment box 81 is in a rectangular shape and is mounted on the back of the chassis 1. The rotating handle 82 is inserted into the adjustment box 81 in a direction perpendicular to the adjustment box 81. One end of the rotating handle 82 extends out of the adjustment box 81, and the rotating rod 83 is coaxially connected to the other end of the rotating handle 82 in a horizontal direction. The first gear 84 is vertically arranged, and the end of the rotating rod 83 away from the rotating handle 82 is coaxially connected to the first gear 84. The first rack 85 is vertically arranged, and the side wall of the first rack 85 is meshed and connected with the first gear 84. At the same time, the first rack 85 is connected to the side wall of the guide plate 2 through the movable rod 9. The position of the first rack 85 is close to the low end of the guide plate 2, and at the same time, the left and right sides of the high end of the guide plate 2 are both hingedly connected to the inner wall of the chassis 1.

[0067] Specifically, when adjusting the inclination angle of the material guide plate 2, the rotating handle 82 is rotated. The rotating handle 82 drives the rotating rod 83 to rotate, and simultaneously drives the first gear 84 to rotate. During the rotation process, the first gear 84 meshes with the first rack 85, and then drives the first rack 85 to rise and fall in the vertical direction through the first gear 84. During the vertical rise and fall process, the first rack 85 drives the material guide plate 2 to rotate through the corresponding movable rod 9. At the same time, a corresponding locking device is installed on the rotating handle 82. When the material guide plate 2 is rotated to an appropriate angle, the rotating handle 82 is locked by the locking device to effectively prevent the material guide plate 2 from changing its angle.

[0068] Specifically, refer to Figure 1 , Figure 3 as well as Figure 6 The bottom of the first rack 85 is provided with a first waist-shaped hole 10 in the horizontal direction, and the back of the chassis 1 is provided with a second waist-shaped hole 11, which is in a curved arc shape. The movable rod 9 is arranged horizontally, one end of the movable rod 9 is integrally connected with the side wall of the guide plate 2, and the other end of the movable rod 9 passes through the second waist-shaped hole 11 and extends into the first waist-shaped hole 10.

[0069] During the rotation and adjustment of the guide plate 2, the overall movement trajectory of the guide plate 2 is arc-shaped. In order to effectively avoid interference between the movement trajectory of the guide plate 2 and the first rack 85 during the rotation and adjustment, the first waist-shaped hole 10 and the second waist-shaped hole 11 are used to keep the movement trajectory of the movable rod 9 equal to the movement trajectory of the guide plate 2, and then the movement interference between the guide plate 2 and the first rack 85 is offset by the movable rod 9, effectively ensuring that the guide plate 2 can be smoothly rotated and adjusted under the drive of the first rack 85.

[0070] Specifically, refer to Figure 2 and Figure 5The lower end of the guide plate 2 is connected to the inner wall of the hot air blower 5 through the left and right first linkage rods 12. When the guide plate 2 rotates, the hot air blower 5 is driven to rise and fall through the two first linkage rods 12. At the same time, in order to avoid motion interference between the rotation of the guide plate 2 and the lifting and falling of the hot air blower 5, the side walls of the two first linkage rods 12 are also provided with corresponding third waist-shaped holes 13, and the third waist-shaped holes 13 are inserted with movable blocks 14. The side walls of the movable blocks 14 are integrally formed with movable plates 15, and the movable plates 15 are installed on the hot air blower 5.

[0071] When the guide plate 2 rotates, the movable block 14 moves in the corresponding third waist-shaped hole 13 and drives the hot air blower 5 to rise and fall through the movable plate 15, so that the air outlet of the hot air blower 5 can always correspond to the lower end of the guide plate 2.

[0072] Specifically, refer to Figure 2 , Figure 4 as well as Figure 7 A second adjusting component 16 is added to the hot air blower 5. When the hot air blower 5 is raised or lowered, the air outlet angle of the wind blades on the hot air blower 5 is adjusted by the second adjusting component 16.

[0073] Specifically, refer to Figure 2 , Figure 7 as well as Figure 8 The second adjustment assembly 16 includes a second rack 161, a second gear 162, a driving gear 163, a driven gear 164, a screw 165, a lifting plate 166 and a second linkage rod 167. The second rack 161 is vertically fixed to the bottom of the inner wall of the hot air blower 5, the second gear 162 is connected to the bottom of the air outlet pipe 7 in the hot air blower 5 through a corresponding connecting rod, and the second gear 162 is meshed and connected with the second rack 161. The driving gear 163 and the driven gear 164 are both located at the bottom of the air outlet pipe 7, the driving gear 163 is vertically arranged, the driven gear 164 is horizontally arranged, the driving gear 163 and the second gear 162 are coaxially connected, and the driven gear 164 is meshed and connected with the driving gear 163. The screw 165 is vertically arranged in the air outlet pipe 7, and the bottom of the screw 165 extends downward out of the air outlet pipe 7, and the driven gear 164 is integrally sleeved to the side of the screw 165. The lifting plate 166 is sleeved on the screw rod 165, and an internal thread hole is formed through the lifting plate 166, and a threaded connection relationship is set between the lifting plate 166 and the screw rod 165 through the internal thread hole. The second linkage rod 167 is vertically arranged, and the side wall of the lifting plate 166 is connected to the top of the second linkage rod 167, and the side wall of the second linkage rod 167 is connected to the fan blade on the air outlet pipe 7, and the left and right ends of the fan blade are hingedly installed on the air outlet pipe 7.

[0074] When the hot air blower 5 is specifically lifted or lowered, the hot air blower 5 drives the second rack 161 to be lifted or lowered, and the second rack 161 meshes with the second gear 162 at the bottom of the air outlet pipe 7 while being lifted or lowered. The second gear 162 drives the driving gear 163 to rotate during the rotation process, and drives the driven gear 164 to rotate through the driving gear 163. The screw 165 is driven by the driven gear 164 to rotate, and the screw 165 drives the lifting plate 166 to be lifted or lowered during the rotation process. While the lifting plate 166 is lifted or lowered, it drives the second linkage rod 167 to be lifted or lowered, and then the lifting or lowering of the second linkage rod 167 drives the fan blades on the air outlet pipe 7 to rotate, thereby adjusting the air outlet angle of the fan blades of the air outlet pipe 7, so that the air outlet angle of the hot air blower 5 can always remain parallel to the inclination angle of the guide plate 2.

[0075] Further, refer to Figure 5 , Figure 7 as well as Figure 8 A fourth waist-shaped hole 17 is installed between the lifting plate 166 and the top of the second linkage rod 167, and a movable block 14 is also integrally connected to the top of the second linkage rod 167, and the movable block 14 is located in the fourth waist-shaped hole 17. When the fan blade rotates, the movable block 14 slides in the fourth waist-shaped hole 17, and then the fourth waist-shaped hole 17 is used to effectively prevent the fan blade from interfering with the lifting and lowering of the lifting plate 166 during the rotation process.

[0076] Further, refer to Figure 2 A material control plate 18 is added to the top of the material guide plate 2 located at the top of the chassis 1. A through hole for the circulation of plastic masterbatch is formed between the material control plate 18 and the material guide plate 2. The material guide plate 2 drives the material control plate 18 to rotate during the rotation process. The material control plate 18 is used to control the number of plastic masterbatch on the material guide plate 2. When the number of plastic masterbatch is large, the inclination angle of the material guide plate 2 is adjusted to be gentle, and the material control plate 18 is rotated in the direction close to the material guide plate 2. In this state, the through hole between the material control plate 18 and the material guide plate 2 becomes smaller, thereby reducing the number of plastic masterbatch passing through the through hole at one time, which can further improve the effect of the hot air blower 5 on drying and removing impurities of the plastic masterbatch. At the same time, in order to effectively prevent the material control plate 18 from hindering the impurity removal process of the hot air blower 5, a filter is also installed on the side wall of the material control plate 18.

[0077] Specifically, both the left and right sides of the first rack 85 are tooth-shaped, and the side of the first rack 85 away from the first gear 84 is meshed with the third gear 19, and a corresponding rotating rod 83 is also provided between the third gear 19 and the top of the material control plate 18, and the rotating rod 83 is coaxially connected with the third gear 19. When the first rack 85 drives the material guide plate 2 to rotate during the lifting process, the first rack 85 is meshed with the third gear 19. In this state, the third gear 19 rotates and drives the material control plate 18 to rotate, thereby controlling the amount of plastic masterbatch through the material control plate 18.

[0078] A pretreatment process for drying plastic masterbatch:

[0079] S1, adding plastic masterbatch into the inside of the chassis 1 from the feed port 3 at the top of the chassis 1. After the plastic masterbatch enters the inside of the chassis 1, it first falls onto the topmost guide plate 2 and is dried and impurity removed by the corresponding hot air blower 5;

[0080] S2, the plastic masterbatch gradually flows to the bottom guide plate 2, and after multi-stage drying and impurity removal, it is finally discharged from the discharge port 4 at the bottom of the chassis 1;

[0081] S3, the inclination of the guide plate 2 is adjusted by the first adjustment component 8, and the guide plate 2 drives the corresponding hot air blower 5 to rise and fall during the adjustment process, and simultaneously drives the fan blades on the hot air blower 5 to rotate, and at the same time, the control plate 18 rotates to control the amount of plastic masterbatch;

[0082] S4, remove the impurity removal boxes 20 on the left and right sides of the chassis 1, and clean the impurities and the filter plates 6 in the impurity removal boxes 20.

[0083] The implementation principle of a pretreatment device and process for drying plastic masterbatch in the embodiment of the present application is as follows:

[0084] Specifically, when processing the plastic masterbatch, the plastic masterbatch is added into the chassis 1 from the feed port 3 at the top of the chassis 1. After entering the chassis 1, the plastic masterbatch first falls onto the uppermost guide plate 2. Since the guide plate 2 is inclined, the plastic masterbatch that falls onto the guide plate 2 flows downward, and gradually flows to the lowermost guide plate 2, and is finally discharged from the discharge port 4 at the bottom of the chassis 1.

[0085] While adding materials into the chassis 1, turn on the hot air blower 5 in the chassis 1. While the plastic masterbatch flows on the guide plate 2, the corresponding hot air blower 5 is located at the low end of the corresponding guide plate 2, and the corresponding filter plate 6 is located just above the high end of the corresponding guide plate 2. While the plastic masterbatch flows downward on the guide plate 2, the hot air from the corresponding hot air blower 5 blows the plastic masterbatch upward. While the hot air blows the plastic masterbatch upward, it blows the dust between the plastic masterbatch upward to the filter plate 6 above the high end of the corresponding guide plate 2. Part of the dust blown upward by the hot air is adsorbed by the filter plate 6, and part of it is carried by the hot air through the filter plate 6 into the corresponding impurity removal box 20.

[0086] When the plastic masterbatch flows downward on the guide plate 2, it is dried by the hot air blown by the corresponding hot air blower 5. At the same time, the hot air blows the dust between the plastic masterbatch upward, adsorbed on the filter plate 6 or falls into the impurity removal box 20. These plastic masterbatch will be dried and impurity-removed multiple times in the process of flowing from the top guide plate 2 to the bottom guide plate 2, and each drying and impurity removal is carried out synchronously. This makes it possible for the plastic masterbatch added from the feed inlet 3 to be discharged from the discharge port 4, and multiple levels of drying and impurity removal will be carried out, and each level of drying and impurity removal is carried out synchronously.

[0087] This setting method can simultaneously remove impurities and dry the plastic masterbatch during processing and production, thereby optimizing the process of daily processing and production of plastic masterbatch, which is beneficial to significantly improve the efficiency of daily processing and production of plastic masterbatch.

[0088] 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.
