Abstract
Description
Technical Field
[0001] This utility model relates to the field of drying equipment technology, and in particular to a drying device for blow-suction composite masterbatch. Background Technology
[0002] In the field of plastics processing, masterbatch plays an important role. Masterbatch is a concentrated mixture of pigments or additives and carrier resins. It is widely used to impart various special properties to plastics. Among them, blown and suction composite masterbatch has unique processing requirements due to its complex structure and composition, so a drying device for blown and suction composite masterbatch is needed.
[0003] A search revealed Chinese patent publication number CN110779292A, which discloses a masterbatch drying device for composite wood door production. The device includes a frame, a mounting base at the bottom of the frame, and a protective cover above the mounting base. A stepper motor is housed within the protective cover. The stepper motor is fixedly connected to a driving bevel gear via a rotating shaft. The driving bevel gear meshes with a driven bevel gear. Two driven bevel gears are provided, symmetrically arranged, with connecting shafts fixed to their opposite sides. These connecting shafts connect to a channel pipe, and storage containers are provided at both ends of the channel pipe. The two storage containers are connected to the channel pipe... The pipes are interconnected and linked together. A hot air blower is installed on the side of the frame. The hot air blower has an air outlet pipe at its outlet. The air outlet pipe is movably sleeved inside the rotating shaft. An air outlet hole is opened at the end of the rotating shaft where it overlaps with the channel pipe. The air outlet pipe is connected to the air outlet hole and is connected to the channel pipe through the air outlet hole. However, the air outlet hole delivers hot air into the channel pipe to dry the masterbatch. When the hot air blown out of the hot air blower enters the channel pipe through the air outlet pipe, the hot air is difficult to evenly cover the masterbatch in all positions of the channel pipe because the position of the air outlet hole is fixed. This prevents the masterbatch from fully contacting the hot air, resulting in uneven drying. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a drying device for blow-suction composite masterbatch, which aims to improve the problem in the prior art where the hot air cannot evenly cover the masterbatch in various positions in the channel tube due to the fixed position of the air outlet, resulting in the masterbatch not being able to fully contact the hot air and causing uneven drying.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a drying device for blow-suction composite masterbatch, comprising a drying chamber, hinge one, and hinge two. A feed inlet is fixedly connected to the top left side of the drying chamber. An inclined plate is fixedly connected to the top left side of the inner wall of the drying chamber. A fixed barrel is fixedly connected to the middle of the inner wall of the drying chamber. A feed inlet is opened on the top right side of the fixed barrel. The right side of the outer wall of the inclined plate communicates with the outer wall of the feed inlet. A rotating roller is rotatably connected to the inner wall of the fixed barrel. A rotating shaft is fixedly connected to the left side of the outer wall of the rotating roller. The outer wall of the rotating shaft is rotatably connected to the middle left side of the outer wall of the drying chamber. A motor is fixedly connected to the middle left side of the outer wall of the drying chamber. The output end of the motor is fixedly connected to the left end of the outer wall of the rotating roller. A discharge port is opened on the bottom left side of the rotating roller. A sealing plate is provided on the outer wall of the discharge port. A handle is fixedly connected to the bottom of the outer wall of the sealing plate. A discharge plate is fixedly connected to the bottom left side of the inner wall of the drying chamber. Heating mechanisms are provided on both the front and rear sides of the inner wall of the drying chamber.
[0006] The above technical solution involves feeding the masterbatch through the inlet on the top left side of the drying chamber, which slides down the inclined plate to the inlet on the top right side of the fixed barrel. The masterbatch then enters the fixed barrel. The motor is started, and the motor output drives the rotating roller to rotate. The rotating roller rotates stably inside the drying chamber through the rotating shaft, causing the masterbatch to tumble continuously during the rotation, thereby achieving drying. After drying, the handle is held and the sealing plate is pulled to open the outlet on the bottom left side of the rotating roller, and the masterbatch is discharged from the drying chamber through the discharge plate.
[0007] As a further description of the above technical solution:
[0008] The heating mechanism includes two fixed frames. The two fixed frames are respectively fixedly connected to the front and rear sides of the inner wall of the drying oven at opposite ends. The adjacent sides of the two fixed frames are fixedly connected to the front and rear sides of the outer wall of the fixed barrel. Multiple sliding grooves are provided at the upper and lower ends of the outer walls of the two fixed frames. Connecting blocks are slidably connected to the inner walls of the multiple sliding grooves. Heating wires are fixedly connected to the adjacent sides of the multiple connecting blocks. Connecting rods are fixedly connected to the upper and lower ends of the front sides of the two heating wires. Two handles are fixedly connected to one end of the multiple connecting rods.
[0009] The above technical solution involves two fixed frames that are fixed to the middle of the inner wall of the drying chamber and connected to the fixed barrel, providing support for the entire heating mechanism. Multiple sliding grooves are opened on the fixed frames, and the connecting block slides in the sliding grooves. The heating wire fixed on the connecting block can move accordingly. By holding the handle three, the connecting rod can be pushed, thereby driving the heating wire to move along the sliding groove. The distance between the heating wire and the masterbatch in the fixed barrel can be adjusted, so as to achieve flexible control of the heating range and intensity to meet the heat requirements of different drying stages.
[0010] As a further description of the above technical solution:
[0011] The bottom of the drying oven is fixedly connected to support columns around its perimeter, and foot pads are fixedly connected to the bottom ends of the support columns.
[0012] The above technical solution involves installing support columns around the bottom of the drying oven to elevate it and maintain a certain distance from the ground. This prevents moisture and debris from the ground from affecting the drying oven and ensures its stable placement. Foot pads are installed at the bottom of the support columns to increase the friction between the support columns and the ground, preventing the drying oven from sliding during operation and enhancing the stability of the equipment.
[0013] As a further description of the above technical solution:
[0014] A controller is fixedly connected to the top right side of the front end of the drying oven, and the controller is electrically connected to the motor.
[0015] The above technical solution involves an electrical connection between a controller fixedly connected to the top right side of the drying chamber and the motor. The operator sends commands through the controller, which transmits electrical signals to the motor to control its operation, thereby regulating the rotating rollers to dry the masterbatch.
[0016] As a further description of the above technical solution:
[0017] A rotating door is provided on the top right side of the drying oven. The front and rear ends of the top right side of the rotating door are rotatably connected to the top right side of the drying oven via a hinge.
[0018] The above technical solution involves a rotating door located on the top right side of the drying chamber. The front and rear ends of the rotating door are connected to the drying chamber via threaded hinges. The opening and closing of the rotating door facilitates operation and maintenance of the drying chamber while ensuring the airtightness of the drying process.
[0019] As a further description of the above technical solution:
[0020] The top left side of the rotating door is provided with an installation groove, and a handle is fixedly connected to the inner wall of the installation groove.
[0021] The above technical solution involves a mounting groove on the top left side of the revolving door, with a handle fixed to the inner wall of the mounting groove. Users can easily open or close the revolving door by holding the handle.
[0022] As a further description of the above technical solution:
[0023] A rotating door 2 is provided at the top of the feed inlet. The front and rear ends of the right side of the outer wall of the rotating door 2 are rotatably connected to the left side of the outer wall of the feed inlet via a hinge 2.
[0024] The above technical solution involves a rotating door at the top of the feed inlet. The front and rear ends of the right side of the rotating door are connected to the feed inlet via threaded hinges. The opening and closing of the rotating door allows for the addition of masterbatch and prevents heat leakage and impurities from entering during the drying process.
[0025] As a further description of the above technical solution:
[0026] The outer wall of the rotating door 2 has an installation groove 2 on the left side, and a handle 2 is fixedly connected to the inner wall of the installation groove 2.

[0028] This utility model has the following beneficial effects:
[0029] 1. In this utility model, the rotating roller is driven by a motor to rotate, so that the masterbatch is fully tumbled in the fixed barrel, thereby increasing the contact area between the masterbatch and the drying environment. At the same time, it ensures that each masterbatch is heated evenly, effectively improving the uniformity of drying, avoiding over-drying of some masterbatch, ensuring the stability of product quality, and thus effectively improving production efficiency.
[0030] 2. In this utility model, the heating function of the heating wire provides an auxiliary function for the drying of masterbatch. During the drying process of masterbatch, the heat generated by the heating wire is transferred to the fixed barrel to achieve auxiliary heating of masterbatch, which accelerates the evaporation of moisture and effectively improves the drying efficiency. It enables the masterbatch to reach the drying standard in a shorter time and improves the efficiency of the entire production process. Attached Figure Description

A discharge plate 13 is fixedly connected to the bottom left side of the inner wall of the drying chamber 1. Heating mechanisms 2 are provided on both the front and rear sides of the inner wall of the drying chamber 1.
[0040] Specifically, the feed inlet 3 on the top left of the drying chamber 1 is the entrance for the masterbatch, through which the material enters. The inclined plate 4 on the top left of the inner wall guides the masterbatch into the fixed barrel 5 through the feed inlet 6 on the top right of the fixed barrel 5. The rotating roller 7, which is rotatably connected inside the fixed barrel 5, is connected to the drying chamber 1 through the rotating shaft 8 on the left side of the outer wall. The rotating roller 7 is driven by the motor 9 in the middle of the left side of the outer wall of the drying chamber 1. When the motor 9 is running, it drives the rotating roller 7 to rotate, causing the masterbatch inside to tumble and achieve drying. The discharge port 10 on the bottom left of the rotating roller 7 is sealed by the sealing plate 11 with a handle 12 during drying to prevent heat and impurities from entering or leaving. After drying, the handle 12 is held to open the sealing plate 11, and the masterbatch is discharged from the discharge port 10. The discharge plate 13 on the bottom left of the inner wall of the drying chamber 1 guides the discharged masterbatch to flow smoothly out of the drying chamber 1.

[0041] Reference Figure 1 , Figure 3 and Figure 5 The heating mechanism 2 includes two fixed frames 201. The two fixed frames 201 are fixedly connected to the front and rear sides of the inner wall of the drying oven 1 on opposite sides.

[0042] Specifically, the two fixed frames 201 are fixed to the front and rear sides of the middle of the inner wall of the drying oven 1, respectively, and the adjacent side is connected to the front and rear sides of the outer wall of the fixed barrel 5, providing a stable support structure for the entire heating mechanism 2. The upper and lower ends of the outer wall of the fixed frame 201 are provided with multiple sliding grooves 202. The connecting block 203 slides in the sliding groove 202. The heating wire 204 is fixed on the connecting block 203. When the heating wire 204 is energized, it generates heat to dry the masterbatch in the fixed barrel 5. In order to facilitate the adjustment of the position of the heating wire 204, the connecting rod 205 is fixed at the upper and lower ends of the front side of the heating wire 204. One end of the connecting rod 205 is connected to two handles 206. The operator holds the handles 206 and drives the connecting block 203 to slide in the sliding groove 202 through the connecting rod 205, thereby changing the distance between the heating wire 204 and the fixed barrel 5, and flexibly adjusting the heating intensity and range.
[0043] Reference Figure 1 , Figure 2 and Figure 3The bottom of the drying oven 1 is fixedly connected to support columns 14 on all four sides, and foot pads 15 are fixedly connected to the bottom of the multiple support columns 14; a controller 16 is fixedly connected to the top right side of the front of the drying oven 1, and the controller 16 is electrically connected to the motor 9; a rotating door 17 is provided on the top right side of the drying oven 1, and the front and rear ends of the top right side of the rotating door 17 are rotatably connected to the top right side of the drying oven 1 through hinges 18.
[0044] Specifically, the support column 14 supports the drying chamber 1 to avoid the influence of adverse ground factors, while the foot pads 15 increase friction and cushioning to ensure the stable placement of the drying chamber 1. The controller 16 on the top right side of the front of the drying chamber 1 is electrically connected to the motor 9. As the control core, the controller 16 can receive operator commands and send electrical signals to the motor 9 to precisely control the start, stop and speed of the motor 9. A rotating door 17 is provided on the top right side of the drying chamber 1, which is connected to the drying chamber 1 via a hinge 18 with threads at the front and rear ends on the top right side. The rotating door 17 can be installed stably and rotated flexibly, making it convenient for operators to inspect and maintain the interior of the drying chamber 1.
[0045] Reference Figure 2 , Figure 4 and Figure 5 A mounting groove 19 is provided on the top left side of the rotating door 17, and a handle 20 is fixedly connected to the inner wall of the mounting groove 19; a rotating door 21 is provided on the top of the feed inlet 3, and the front and rear ends of the right side of the rotating door 21 are rotatably connected to the left side of the outer wall of the feed inlet 3 through the hinge 22; a mounting groove 23 is provided on the left side of the outer wall of the rotating door 21, and a handle 24 is fixedly connected to the inner wall of the mounting groove 23;
[0046] Specifically, a handle 20 is fixed in the mounting groove 19 on the top left side of the rotating door 17. The mounting groove 19 provides a stable mounting base for the handle 20. By holding the handle 20, the operator can easily open or close the rotating door 17 for inspection and maintenance of the interior of the drying chamber 1. The rotating door 21 at the top of the feed inlet 3 is connected to the feed inlet 3 by a hinge 22 with threads at the front and rear ends on the right side of the outer wall. The hinge 22 ensures the stable installation and flexible rotation of the rotating door 21. The rotating door 21 can be opened when adding masterbatch and closed after adding to prevent heat loss and impurities from entering. The handle 24 fixed in the mounting groove 23 on the left side of the outer wall of the rotating door 21 provides the operator with a force point to operate the rotating door 21. By holding the handle 24, the operator can easily control the opening and closing of the rotating door 21, so as to effectively maintain the material addition at the feed inlet 3 and the drying environment.
[0047] Working principle: When using the blowing and suction composite masterbatch drying device, the composite masterbatch enters from the feed port 3 on the top left side of the drying chamber 1, flows along the inclined plate 4 on the top left side of the inner wall of the drying chamber 1, and flows into the fixed barrel 5 through the feed port 6 on the top right side of the fixed barrel 5. The motor 9 in the middle of the left side of the outer wall of the drying chamber 1 is started. The output end of the motor 9 drives the rotating shaft 8 of the rotating roller 7, so that the rotating roller 7 rotates in the fixed barrel 5, thereby causing the masterbatch inside to tumble. After the masterbatch is dried, the operator holds the handle 12 at the bottom of the sealing plate 11 and opens the sealing plate 11 of the discharge port 10 on the bottom left side of the rotating roller 7. The dried masterbatch falls from the discharge port 10 and is discharged from the device through the discharge plate 13 on the bottom left side of the inner wall of the drying chamber 1.
[0048] Furthermore, the heating mechanism 2 is securely installed in the middle of the inner wall of the drying chamber 1 by two fixed brackets 201 and connected to the fixed barrel 5, ensuring structural stability. When it is necessary to assist in drying the blow-suction composite masterbatch in the fixed barrel 5, the heating wire 204 is energized, and the heating wire 204 generates heat, which is transferred to the fixed barrel 5 to assist in heating the masterbatch. When it is necessary to adjust the heating intensity and range, the operator holds the handle 206 and drives the connecting rod 205 through the handle 206. The connecting rod 205 then drives the connecting block 203 connected to it. Since the connecting block 203 is slidably connected in the sliding groove 202 at the upper and lower ends of the outer wall of the fixed bracket 201, the connecting block 203 can slide in the sliding groove 202, thereby changing the distance between the heating wire 204 and the fixed barrel 5. When the heating wire 204 is close to the fixed barrel 5, the heating intensity increases, and when it is far away, the heating intensity decreases, thereby meeting different drying needs.
[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
