Description

Technical Field

[0001] This utility model relates to the field of oil pastel technology, and in particular to an oil pastel raw material mixing mechanism. Background Technology

[0002] Oil pastels are oil-based colored drawing tools, typically cylindrical or prismatic in shape and about 10 centimeters long. Similar in appearance to crayons, they have stronger adhesion and covering power on paper, creating an oil painting-like effect. Oil pastels have a smooth, delicate feel, excellent spreadability, and superior layering and mixing properties. Compared to crayons, oil pastels offer more vibrant colors and stronger adhesion and covering power on paper, making them one of children's favorite drawing tools.

[0003] Chinese Patent Authorization Announcement No.: CN 212289355 U, Authorization Announcement Date: January 5, 2021. This utility model proposes an oil pastel raw material mixing system, including a mixing box (7). The mixing box (7) is characterized by: a guide hopper (5) is provided on the top of the mixing box (7), a sealing plate (6) is rotatably installed inside the guide hopper (5) through a bearing, an elastic limiting pad (23) is provided around the outside of the sealing plate (6), an adjustment knob (17) is rotatably installed on one side of the sealing plate (6) through the surface of the guide hopper (5), a grinding chamber (4) is integrally formed on the top of the guide hopper (5), an active roller (3) is rotatably installed inside the grinding chamber (4) through a rotating shaft (2), a driven roller (1) is rotatably installed on one side of the active roller (3) through a rotating shaft (2), the active roller (3) and the driven roller (1) mesh with each other, and a grinding motor (18) is fixedly installed on one end of the active roller (3) through the grinding chamber (4). The drawback of this technical solution is that the oil pastel raw materials need to be pre-portioned and then added to the mixing system in sequence, which affects the mixing efficiency and leads to a decrease in productivity.

[0004] In summary, existing oil pastel materials suffer from low mixing efficiency, leading to decreased productivity. Utility Model Content

[0005] This invention aims to overcome the shortcomings of existing technologies where low mixing efficiency during the mixing of oil pastel materials leads to decreased productivity, and provides an oil pastel material mixing mechanism that improves mixing efficiency and thus increases productivity.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An oil pastel material mixing mechanism, comprising

[0008] Mixing bin;

[0009] The feeding assembly is connected to the upper end of the mixing box, and the feeding assembly is movably connected to a limited structure;

[0010] Anti-blocking rod, which is movably connected to the feeding assembly;

[0011] Mixing fan blades are rotatably connected to the mixing box;

[0012] The discharge assembly is connected to the lower end of the mixing box and is connected to a guide plate.

[0013] The premixed structure is connected to a drive component, and the premixed structure is moved and connected to the mixing tank through the drive component.

[0014] The mixing hopper is fed by a feeding assembly connected to a limiting structure. This limiting structure quantitatively feeds the raw materials, saving feeding time and improving efficiency. An anti-blocking rod prevents raw materials from piling up during feeding, thus reducing feeding resistance and further improving efficiency. Mixing fan blades rotate within the mixing hopper to mix the incoming raw materials for later shaping of the oil pastels. The discharging assembly, connected to the bottom of the mixing hopper, quickly discharges the mixed materials guided by a guide plate, ensuring continuous operation. A pre-mixing structure pre-mixes the raw materials before the mixing fan blades, improving mixing thoroughness and efficiency. This system achieves improved mixing thoroughness and efficiency, quantitative feeding, convenient and rapid feeding and discharging, and ultimately increased productivity.

[0015] Preferably, the feeding assembly includes a raw material bucket and a discharge pipe. The mixing tank has a feed inlet, and the raw material bucket is connected to the feed inlet. The raw material bucket has a raw material hole, and the discharge pipe is connected to the raw material hole. One end of the anti-blocking rod is movably connected to the raw material bucket, and the other end of the anti-blocking rod is inserted into the discharge pipe. The diameter of the anti-blocking rod is smaller than the inner diameter of the discharge pipe. Several raw material buckets and discharge pipes are provided to separately store and discharge different raw materials. The raw material bucket is connected to the feed inlet, and the discharge pipe is connected to and communicates with the raw material bucket through the raw material hole. The discharge pipe extends into the mixing tank through the feed inlet, allowing the raw material in the bucket to enter the mixing tank through the discharge pipe for controlled feeding. The anti-blocking rod is movably connected to the raw material bucket and inserted into the discharge pipe to disperse the raw material in the bucket and clear the discharge pipe. The anti-blocking rod is cylindrical, and its diameter is smaller than the inner diameter of the discharge pipe to ensure normal raw material flow. This achieves the effects of improving the connection and operational stability between structures and increasing feeding efficiency.

[0016] Preferably, the raw material bucket is connected to a bracket, which is connected to the mixing tank. The raw material bucket has an insertion hole, into which an anti-blocking rod is inserted. The anti-blocking rod is fitted with a top plate and an elastic mechanism. One end of the elastic mechanism is connected to the top plate, and the other end is connected to the raw material bucket. The raw material bucket is fixed to the mixing tank by the connecting bracket. The anti-blocking rod, inserted into the raw material bucket, moves elastically through the elastic mechanism, thus facilitating stable unblocking operation. This improves the stability of the structure's installation and operation.

[0017] Preferably, the limiting structure includes a metering box, a support plate, and a tilting plate. A blocking block is connected to the other end of an anti-blocking rod, and the blocking block is inserted into the lower end of the discharge pipe. One end of the support plate is connected to the mixing tank, and the other end of the tilting plate is connected to the support plate. The lower end of the metering box is connected to the tilting plate, and the other end of the metering box has a feeding chute, which is arranged vertically opposite to the discharge pipe. In the limiting structure, the metering box is connected inside the mixing tank and placed below the discharge pipe. Supported by the tilting plate, it receives the raw material through the feeding chute when the discharge pipe discharges, and then the blocking block seals the discharge pipe for metered feeding, thus achieving quantitative feeding of raw materials and improving mixing efficiency. This achieves the effect of quantitative feeding and thus improving continuous mixing efficiency.

[0018] Preferably, the mixing bin is equipped with mounting holes through which a push rod is inserted. The support plate has a connecting groove, and the tilting plate is connected to a rotating rod, which is inserted into the connecting groove. The tilting plate is rotatably connected to the support plate via the push rod. The push rod is inserted into the mounting holes, and the tilting plate is rotatably connected to the support plate via the rotating rod. The push rod pushes the tilting plate, switching it between vertical and horizontal orientations, thus enabling rapid switching between the collecting and discharging states of the metering box. This improves structural connection and operational stability, further enhancing mixing efficiency.

[0019] Preferably, the discharge assembly includes a movable base plate and a control rod. One end of the movable base plate has a tilting groove, which is arranged opposite to the mixing fan blades. The mixing box is equipped with a guide rail. One end of the control rod is slidably connected to the guide rail, and the other end is connected to the other end of the movable base plate. A guide plate is connected to the mixing box and positioned below the movable base plate. The tilting groove of the movable base plate automatically collects and mixes materials as the mixing fan blades rotate, improving mixing efficiency. The control rod is connected to the guide rail of the mixing box to control the movement of the movable base plate, allowing the movable base plate (tilting groove) to approach the mixing fan blades as closely as possible for thorough mixing. Furthermore, by rotating the control rod after it has moved down the guide rail, the mixed material from the tilting groove can fall into the guide plate under gravity for centralized discharge. This achieves the effects of improved mixing efficiency and thoroughness, and facilitates centralized discharge.

[0020] Preferably, the premixing structure includes a sieve plate and a return spring. The sieve plate is connected to a screen, and the mixing box has a mounting slot. The sieve plate is inserted into the mounting slot. One end of the return spring is connected to the mixing box, and the other end is connected to one end of the sieve plate. The drive assembly is movably connected to the mixing box, and the other end of the sieve plate is movably connected to the drive assembly. The sieve plate in the powder sieve is inserted into the mounting slot of the mixing box. The sieve plate has several sieve holes, the size of which allows the raw material to pass through. Driven by one side and rebounding by the other, the sieve plate can move horizontally back and forth, thereby achieving premixing of the raw material after quantitative feeding and making the raw material mix more quickly. This improves mixing efficiency, enhances the degree of automation, and ultimately improves work efficiency.

[0021] Preferably, the drive assembly includes a rotating mechanism and a pusher block. The rotating mechanism is connected to the mixing tank, and one side of the pusher block is connected to the rotating mechanism. The pusher block is movably connected to the screen plate. The rotating mechanism, connected to the mixing tank, and the pusher block, connected to the rotating mechanism, provides rotational driving force to the pusher block, which, in conjunction with a return spring, pushes the screen plate during rotation. This improves the operational flexibility of the structure.

[0022] The beneficial effects of this utility model are: improved mixing fullness and efficiency; quantitative feeding, facilitating rapid feeding and unloading; convenient operation, thereby improving productivity; improved connection and operational stability between structures; improved structural installation; enhanced operational automation; and increased operational flexibility.
