Description

Technical Field

[0001] This utility model relates to the field of drying technology, specifically a protective mechanism for drying injection molding masterbatch. Background Technology

[0002] Masterbatch, also known as plastic masterbatch or masterbatch material, is a plastic processing aid developed in the 1980s. It is composed of a large amount of chemical additives, carrier resin, and dispersants. Masterbatch is an aggregate obtained by uniformly loading a large amount of pigment (dye) into the resin. In the plastic processing molding process, for the convenience of operation, various additives, fillers and a small amount of carrier resin are mixed and kneaded, and then processed by extruders and other equipment through metering, mixing, melting, extrusion and pelletizing. Masterbatch is composed of carrier resin, various fillers and various additives. The limit of additives or the content of fillers in masterbatch is several to ten times higher than the amount required in the actual plastic product. In the molding process, the ratio of masterbatch to matrix resin must be adjusted according to the content of relevant components in the masterbatch and the amount required in the actual product. Masterbatch can usually be divided into ordinary filler masterbatch (referred to as filler masterbatch) and functional masterbatch, such as color masterbatch, anti-fogging masterbatch, etc.

[0003] For example, application number 202021280222.0 discloses a masterbatch drying device for plastic product processing, including a main chamber. A first feed inlet is fixed to the top of the main chamber. A protective cover is movably connected to one end of the main chamber. Handles are fixed to both sides of the protective cover away from the main chamber. A second feed inlet and a drying mechanism are sequentially fixed to the end of the main chamber away from the protective cover. Fixed blocks are fixed to both sides of the main chamber away from the protective cover. A movable mechanism is fixed to the bottom of the fixed blocks. A load-bearing plate is fixed to the bottom of the movable mechanism. Support columns are fixed to the four ends of the load-bearing plate. A receiving box is fixed to the end of the load-bearing plate near the protective cover. Beneficial effects: Through a series of improvements, the device can not only dry materials but also crush and mix larger pieces of material, and effectively prevent materials from sticking to the inner wall of the device.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment, while the aforementioned equipment can solve the problem of insufficient drying effect of existing devices in the processing and production of masterbatch, and only has one function of drying, it cannot meet the actual work requirements. Other processes require other devices, which is time-consuming and labor-intensive. However, during use, the heating rod generates high temperatures on its surface when heated, and the masterbatch can directly contact it, causing it to melt and stick. This results in a layer of masterbatch adhering to the surface of the heating rod, which causes the heat of the heating rod to dissipate too slowly, leading to excessively high local temperatures and eventually damage to the heating rod. Utility Model Content

The bottom of the hydraulic cylinder is movably connected to both sides of the left side of the top of the support platform via pivot pins. The inner side of the output end of the hydraulic cylinder is movably connected to the left side of both sides of the heating tank via pivot pins. The right side of the motor is fixedly connected to the left side of the heating tank, and the output end of the motor extends through to the left side of the inner wall of the heating tank. The left side of the support rod is fixedly connected to the output end of the motor. The inner side of the heating rod is fixedly connected to the top and bottom of the support rod. Several heating rods are provided and are evenly distributed. The two sides of the inner side of the stirring blade are fixedly connected to the two sides of the front and back of the support rod. The front sides of the top and bottom of the heating rod are movably connected to a first mesh cover via hinges. The rear sides of the top and bottom of the heating rod are movably connected to a second mesh cover via hinges. The inner sides of the first mesh cover and the second mesh cover are in contact. A fixed closing mechanism is fixedly connected to the right side of the back of the first mesh cover.

[0007] In a preferred embodiment of this utility model, the fixing and closing mechanism includes a convex block. The front of the convex block is fixedly connected to the right side of the back of the first mesh cover. A groove is provided on the right side of the front of the second mesh cover. The convex block is located inside the groove. Mounting slots are provided on both the outer and inner sides of the inner wall of the groove. A locking block is slidably connected to the inner wall of the mounting slot. The back of the locking block contacts the inner and outer sides of the front of the convex block. A spring is fixedly connected to the inner and outer sides of the locking block. The other end of the spring is fixedly connected to the inner and outer sides of the inner wall of the mounting slot. An unlocking component is provided on the right side of the inner wall of the mounting slot.

[0008] As a preferred embodiment of this utility model, the unlocking component includes a sliding groove, which is formed on the right side of the inner wall of the mounting groove. The right side of the inner wall of the sliding groove extends to the right side of the second mesh cover. A slider is fixedly connected to both the inner and outer sides of the right side of the locking block. The surface of the slider is slidably connected to the inner wall of the sliding groove. A symmetrical moving component is movably connected to the right side of the slider via a pivot pin.

[0009] As a preferred embodiment of this utility model, the symmetrical moving component includes a rotating rod, the left side of which is movably connected to the right side of the slider via a pivot pin, and a main rod is provided on the right side of the second mesh cover, both sides of which are movably connected to the inner and outer rear sides of the rotating rod via pivot pins.

[0010] As a preferred embodiment of this utility model, a trapezoidal groove is provided on the left side of the main rod, and a trapezoidal rod is slidably connected to the inner wall of the trapezoidal groove.

[0011] As a preferred embodiment of this utility model, baffles are fixedly connected to both the inner and outer sides of the right side of the slider, and the left side of the baffles is slidably connected to the right side of the second mesh cover.

[0012] As a preferred embodiment of this invention, an enlarged handle is fixedly connected to the right side of the main rod, and the enlarged handle is used to push the main rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model encloses the heating rod by setting a first mesh cover and a second mesh cover. When the heating rod dissipates heat, the masterbatch is blocked by the first and second mesh covers and cannot directly contact the heating rod. This solves the problem that when the heating rod is heated, the surface of the heating rod will generate high temperature, but the masterbatch can directly contact it and melt and stick to it. As a result, a layer of masterbatch adheres to the surface of the heating rod, which causes the heat of the heating rod to dissipate too slowly, resulting in excessively high local temperature of the heating rod and damage to the heating rod in the long run. This invention achieves the effect of protecting the heating rod.

[0015] 2. This utility model, by setting a fixed closing mechanism, during the closing process of the first and second mesh covers, the convex block is inserted into the groove and squeezes the locking block. Subsequently, the locking block retracts into the mounting groove, and the spring is deformed by the compression to generate a rebound force. Then, when the convex block is fully inserted into the groove, the rebound force of the spring immediately pushes the locking block to reset, so that the locking block locks the convex block, thereby realizing the fixed closure of the first and second mesh covers and isolating and protecting the heating rod.

[0016] 3. By setting an unlocking component, when the heating rod needs maintenance and the first mesh cover and the second mesh cover need to be separated, the slider is pulled to move outward symmetrically along the track of the slide groove, so that the locking block retracts into the mounting groove, the spring is squeezed, and the locking block disengages from the convex block. Then the first mesh cover and the second mesh cover lose their closure and can be separated. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 3As shown, this utility model provides a protective mechanism for drying injection molding masterbatch, including a support platform 1, a heating tank 2, a hydraulic cylinder 3, a motor 4, a bearing rod 5, a heating rod 6, and a stirring blade 7. The right side of the bottom of the heating tank 2 is movably connected to the right side of the top of the support platform 1 via a pivot pin. The bottom of the hydraulic cylinder 3 is movably connected to both sides of the top left side of the support platform 1 via a pivot pin. The inner side of the output end of the hydraulic cylinder 3 is movably connected to the left side of both sides of the heating tank 2 via a pivot pin. The right side of the motor 4 is fixedly connected to the left side of the heating tank 2, and the output end of the motor 4 extends through to the left side of the inner wall of the heating tank 2. The left side of rod 5 is fixedly connected to the output end of motor 4. The inner side of heating rod 6 is fixedly connected to the top and bottom of support rod 5. Several heating rods 6 are provided and are evenly distributed. The two sides of the inner side of stirring blade 7 are fixedly connected to the two sides of the front and back of support rod 5. The front sides of the top and bottom of heating rod 6 are movably connected to the first mesh cover 8 through hinges. The rear sides of the top and bottom of heating rod 6 are movably connected to the second mesh cover 9 through hinges. The inner sides of the first mesh cover 8 and the second mesh cover 9 are in contact. The right side of the back of the first mesh cover 8 is fixedly connected to the fixed closing mechanism 10.

[0023] refer to Figure 2 and Figure 3 The fixed closing mechanism 10 includes a convex block 101. The front of the convex block 101 is fixedly connected to the right side of the back of the first mesh cover 8. A groove 102 is provided on the right side of the front of the second mesh cover 9. The convex block 101 is located inside the groove 102. The outer and inner sides of the inner wall of the groove 102 are provided with mounting grooves 103. A locking block 104 is slidably connected to the inner wall of the mounting groove 103. The back of the locking block 104 is in contact with the inner and outer sides of the front of the convex block 101. A spring 105 is fixedly connected to the inner and outer sides of the locking block 104. The other end of the spring 105 is fixedly connected to the inner and outer sides of the inner wall of the mounting groove 103. An unlocking component 11 is provided on the right side of the inner wall of the mounting groove 103.

[0024] As a technical optimization of this utility model, by setting a fixed closing mechanism 10, during the closing process of the first mesh cover 8 and the second mesh cover 9, the convex block 101 will be inserted into the groove 102 and squeeze the locking block 104. Subsequently, the locking block 104 will retract into the mounting groove 103, and the spring 105 will be deformed by the compression to generate a rebound force. Then, when the convex block 101 is fully inserted into the groove 102, the rebound force of the spring 105 will immediately push the locking block 104 to reset, so that the locking block 104 locks the convex block 101, thereby realizing the fixed closure of the first mesh cover 8 and the second mesh cover 9, and isolating and protecting the heating rod 6.

[0025] refer to Figure 3The unlocking component 11 includes a slide groove 111, which is located on the right side of the inner wall of the mounting groove 103. The right side of the inner wall of the slide groove 111 extends to the right side of the second mesh cover 9. Slider 112 is fixedly connected to both the inner and outer sides of the right side of the locking block 104. The surface of the slider 112 is slidably connected to the inner wall of the slide groove 111. A symmetrical moving component 12 is movably connected to the right side of the slider 112 via a pivot pin.

[0026] As a technical optimization of this utility model, by setting the unlocking component 11, when the heating rod 6 needs maintenance and the first mesh cover 8 and the second mesh cover 9 need to be separated, the slider 112 is pulled to move outward symmetrically along the track of the slide groove 111, so that the locking block 104 retracts into the mounting groove 103, so that the spring 105 is squeezed, thereby causing the locking block 104 to disengage from the convex block 101, and then the first mesh cover 8 and the second mesh cover 9 lose their closure and can be separated.

[0027] refer to Figure 3 The symmetrical moving component 12 includes a rotating rod 121. The left side of the rotating rod 121 is movably connected to the right side of the slider 112 via a pivot pin. The right side of the second mesh cover 9 is provided with a main rod 122. Both sides of the main rod 122 are movably connected to the inner and outer rear sides of the rotating rod 121 via pivot pins.

[0028] As a technical optimization of this utility model, by setting up a symmetrical moving component 12, when the user needs to operate with one hand to make the two sliders 112 move symmetrically, the main rod 122 is pushed, so that the rotating rod 121 between the slider 112 and the straight rod rotates from the inclined state to the vertical state, pushing the two sliders 112 outward at the same time, thereby realizing the symmetrical movement of the two side locking blocks 104, so that the locking blocks 104 disengage from the convex block 101 at the same time, thus making it easier for the user to use their other hand to separate the first mesh cover 8 and the second mesh cover 9.

[0029] refer to Figure 3 A trapezoidal groove 13 is provided on the left side of the main rod 122. A trapezoidal rod 14 is slidably connected to the inner wall of the trapezoidal groove 13. The left side of the trapezoidal rod 14 is fixedly connected to the right side of the second mesh cover 9.

[0030] As a technical optimization of this utility model, by setting a trapezoidal groove 13 and a trapezoidal rod 14, when the main rod 122 moves, the trapezoidal rod 14 slides in the trapezoidal groove 13, thereby restricting the movement direction of the main rod 122, so that the main rod 122 moves stably in parallel, and prevents rotation or offset from causing uneven symmetrical movement distance of the two sliders 112.

[0031] refer to Figure 3 The inner and outer sides of the right side of the slider 112 are fixedly connected to baffles 15, and the left side of the baffles 15 is slidably connected to the right side of the second mesh cover 9.

[0032] As a technical optimization of this utility model, by setting a baffle 15, when the slider 112 moves, the baffle 15 moves accordingly, thereby blocking the slide groove 111, thus preventing smaller particles from entering the mounting groove 103 through the slide groove 111 and affecting the compressible distance of the spring 105.

[0033] refer to Figure 3 An enlarged handle 16 is fixedly connected to the right side of the main rod 122. The enlarged handle 16 is used to push the main rod 122.

[0034] As a technical optimization of this utility model, by setting an enlarged handle 16, the force-bearing area when the user pushes the main rod 122 is increased, making it easier to apply force and convenient to push the main rod 122 to perform the unlocking operation, thereby improving the convenience of operation.

[0035] The working principle and usage process of this utility model are as follows: Before heating and drying the injection molding masterbatch, first rotate the first screen cover 8 and the second screen cover 9 to close them. The convex block 101 will then insert into the groove 102, pressing the locking block 104 and causing it to retract into the mounting groove 103. This compression causes the spring 105 to deform and generate a rebound force. Subsequently, once the convex block 101 is fully inserted into the groove 102, the rebound force of the spring 105 immediately pushes the locking block 104. The reset mechanism allows the locking block 104 to hold the convex block 101 in place, thereby securing the first mesh cover 8 and the second mesh cover 9. This provides a secure isolation and protection for the heating rod 6, preventing the masterbatch from directly contacting and adhering to the heating rod 6, which could affect heat dissipation and cause localized overheating and damage. At this point, the user can pour the injection masterbatch into the heating tank 2 through the inlet, then start the heating rod 6 to raise its temperature and dissipate heat, increasing the internal temperature of the heating tank 2, and finally start the motor. 4. Drive the bearing rod 5 to rotate, causing the agitator 7 and heating rod 6 to rotate, thus allowing the heating rod 6 to evenly dissipate heat into the heating tank 2 until the drying of the masterbatch is completed. Then, the lid on the right side of the heating tank 2 can be opened, and the hydraulic cylinder 3 can be activated to pour the masterbatch in the heating tank 2 into the pre-placed box. Later, when the heating rod 6 needs maintenance or repair after prolonged use, the main rod 122 can be pushed by expanding the handle 16, causing the rotating rod 121 between the slider 112 and the straight rod to move from an inclined state to a vertical state. Rotating in the upright position, the two sliders 112 are simultaneously pushed outward along the track of the slide groove 111, pulling the sliders 112 to move symmetrically outward along the track of the slide groove 111, causing the locking block 104 to retract into the mounting groove 103, so that the spring 105 is compressed again and deformed, thereby causing the locking block 104 to disengage from the convex block 101. Then the first mesh cover 8 and the second mesh cover 9 lose their closure and separate, thus allowing the heating rod 6 to be maintained, thereby providing the advantage of protecting the heating rod.

[0036] In summary, this protective mechanism for drying injection molding masterbatch, by setting up a first mesh cover 8 and a second mesh cover 9, encloses the heating rod 6 inside. This prevents the masterbatch from directly contacting the heating rod 6 when it dissipates heat, as the masterbatch is blocked by the first and second mesh covers 8 and 9. This solves the problem that when the heating rod is heated, its surface generates high temperatures, but the masterbatch can directly contact it, melting and sticking to it. This results in a layer of masterbatch adhering to the surface of the heating rod, causing slow heat dissipation, excessively high local temperatures, and eventual damage to the heating rod over time.
