Description

Technical Field

[0001] This invention relates to the field of mixing machine technology, specifically a novel mixing machine that requires no cleaning. Background Technology

[0002] This invention mainly solves the problems of time-consuming and labor-intensive cleaning of the mixing hopper, large consumption of organic solvents, environmental pollution, and occupational hazards in the mixing and color matching process of plastic products. In the mixing and color matching process of plastic products, plastic granules and color powder are directly added to the mixer. After mixing, the mixed material is poured from the mixer into a plastic packaging bag. Then, a large amount of organic solvents such as industrial alcohol, acetone, and methanol are used to clean the inner wall of the mixing hopper and the blades or screw ribbons before the next color can be mixed and matched.

[0003] When cleaning the inner wall of the mixing hopper of existing mixers, especially when there are paddles or ribbons inside the mixing hopper, it is difficult to thoroughly clean many dead corners. This is not only time-consuming and labor-intensive, but also requires a large amount of organic solvents. Furthermore, organic solvents are volatile and have an irritating odor, resulting in a poor working environment and potentially adversely affecting the health of workers. Currently, there are various types of mixers on the market, including vertical mixers, horizontal mixers, V-type mixers, ribbon mixers, double cone mixers, three-dimensional mixers, and ball mill mixers. All of these mixers directly add multiple materials into the mixing hopper, and cleaning of the mixing hopper is unavoidable.

[0004] To address the aforementioned issues, a cleaning-free mixing machine was designed. Plastic packaging bags are placed directly into the mixing hopper, eliminating the need for hopper cleaning, saving time and labor, and conserving organic solvents. Summary of the Invention

[0005] To address the problem that existing mixing machines require cleaning after mixing, which is difficult due to hard-to-reach areas, this invention provides a novel cleaning-free mixing machine.

[0006] The technical solution adopted by this invention to solve its technical problem is:

[0007] A novel, self-cleaning mixing machine, including...

[0008] A mixing hopper, comprising an outer hopper, an inner hopper disposed inside the outer hopper, and a hopper cover disposed on top of the outer hopper, wherein a rotary joint is connected through the inner side of the inner hopper.

[0009] The rotary joint includes a joint body, a first connector is vertically arranged on the inner side of the end of the joint body, and a second connector is horizontally arranged in the middle of the joint body. Both the first connector and the second connector are hollow structures, and the first connector and the second connector are interconnected with the rotary joint.

[0010] A drive mechanism is mechanically connected to the mixing hopper and is used to drive the mixing hopper.

[0011] The driving mechanism includes a first fork and a second fork. The mixing hopper also includes a fixing ring disposed on the outside of the outer hopper. A connecting pin is provided between one end of the first fork and the second fork and the fixing ring. A pin is provided between the other end of the first fork and the second fork and the hollow shaft and the driving shaft.

[0012] The housing has a hollow shaft and a drive shaft respectively installed on its inner side, and the drive mechanism applies a driving force around the axis of the drive shaft.

[0013] A tube is provided between the hollow shaft and the rotary joint, and the tube is interconnected with the hollow shaft and the rotary joint.

[0014] The tube is a flexible hose, and external threads are provided on the outer sides of both ends of the flexible hose. Threaded connection grooves are provided on the inner side of the first connector and the hollow shaft at positions corresponding to the external threads at the ends of the flexible hose.

[0015] Wherein, the straight lines between the first fork and the second fork near the fixed collar are provided with an included angle of at least 70°.

[0016] The fixing collar has a connecting hole at the position corresponding to the connecting pin on its inner side.

[0017] The inner hopper is also equipped with a plastic bag, and the inner hopper has several sets of small holes evenly distributed around its perimeter. These holes are used to suck the plastic bag tightly.

[0018] The flexible hose is threadedly connected to the hollow shaft and the first connector.

[0019] The gas passes sequentially through the first connector, the connector body, and the second connector.

[0020] The beneficial effects of this invention are:

[0021] 1. The present invention discloses a novel self-cleaning mixing machine, which is equipped with a mixing hopper, which is divided into an outer hopper and an inner hopper. A plastic bag is placed in the inner hopper, and the plastic bag is sucked tightly by the small holes on the inner hopper, so that the plastic bag can be tightly attached to the inner wall of the inner hopper. The excess part of the plastic bag is turned outward along the top edge of the inner hopper so that the hopper cover can be closed tightly. The plastic and coloring materials do not directly contact the inner wall of the mixing machine, so no cleaning is required after mixing, which solves the problem of difficult cleaning of traditional mixing machines.

[0022] 2. The novel self-cleaning mixer of the present invention is equipped with a drive mechanism. The drive mechanism drives the mixing hopper to rotate in three dimensions by the axial force provided by the drive shaft, which facilitates the full mixing of the raw materials in the mixing hopper. In addition, if the weight of the raw materials in the mixing hopper is too large, the drive mechanism can be controlled to make the outlet of the mixing hopper face downwards for easy discharge. Compared with the traditional mixing hopper, which can only mix along one axis, this mixing hopper has higher mixing efficiency and more uniform mixing. Attached Figure Description

[0030] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0031] like Figure 1-3 As shown, the present invention provides a novel, no-clean mixing machine, comprising:

[0032] The mixing hopper 1 includes an outer hopper 101, an inner hopper 105 disposed inside the outer hopper 101, and a hopper cover 102 disposed on the top of the outer hopper 101. A rotary joint 104 is connected through the inner side of the inner hopper 105. A flexible hose 3 is disposed between the hollow shaft 5 and the rotary joint 104, and the flexible hose 3 is interconnected with the hollow shaft 5 and the rotary joint 104. The rotary joint 104 includes a joint body 1041, a first connector 1042 is vertically disposed on the inner side of the end of the joint body 1041, and a second connector 104 is horizontally disposed in the middle of the joint body 1041. 3. Both the first connector 1042 and the second connector 1043 are hollow structures, and the first connector 1042 and the second connector 1043 are interconnected with the rotary joint 104. Gas passes through the first connector 1042, the joint body 1041 and the second connector 1043 in sequence. The box body 4 has a hollow shaft 5 and a drive shaft 6 respectively installed on its inner side. A driving force is applied to the drive shaft 6 in the direction of the axis. The inner hopper 105 is also provided with a plastic bag. The inner hopper 105 has several sets of small holes evenly distributed around its perimeter. The small holes are used to suck up the plastic bag.

[0033] Insert the plastic bag into the inner hopper 105, start the air suction unit in the housing 4. The air suction unit can be a vacuum pump. The air suction point of the vacuum pump is connected to the hollow shaft 5. When the vacuum pump is started, the air in the outer hopper 101 of the mixing hopper 1 flows along the second connector 1043, the connector body 1041, the first connector 1042 and the flexible hose 3. Since there are small holes on the inner wall of the inner hopper 105, the air in the inner hopper 105 is sucked away along the above components. Since the plastic bag is placed inside the inner hopper 105, the plastic bag is tightly attached to the inner wall of the inner hopper 105 due to the suction force generated. Flip the excess part of the top of the plastic bag along the outer edge of the top of the inner hopper 105, cover the hopper cover 102, and start mixing.

[0034] Among them, such as Figure 4-5 As shown, the drive mechanism 2 is mechanically connected to the mixing hopper 1 and is used to drive the mixing hopper 1. The drive mechanism 2 includes a first fork 201 and a second fork 202. The mixing hopper 1 also includes a fixing collar 103 disposed on the outside of the outer hopper 101. A connecting pin 204 is provided between one end of the first fork 201 and the second fork 202 and the fixing collar 103. A pin 203 is provided between the other end of the first fork 201 and the second fork 202 and the hollow shaft 5 and the drive shaft 6.

[0035] Inside the housing 4, a drive unit is installed corresponding to the drive shaft 6. The drive unit applies a rotational driving force around the axis to the drive shaft 6. The drive shaft 6 is rotatably connected to the second fork 202 by a pin 203, and the second fork 202 is rotatably connected to the fixed collar 103 by a connecting pin 204. The remaining parts are rotatably connected between the first fork 201 and another set of fixed collars 103, and rotatably connected between the first fork 201 and the hollow shaft 5. Therefore, when the drive shaft 6 rotates, the mixing hopper 1 connected to the fixed collar 103 will rotate regularly, and the rotation direction can be along the X, Y, and Z axes, which can make the raw materials in the mixing hopper 1 more fully and thoroughly mixed.

[0036] After mixing is completed, the outlet direction of mixing hopper 1 can be turned downward by operating the drive mechanism 2, the hopper cover 102 can be opened, and the plastic bag in the inner hopper 105 can be pulled out. Since the raw materials do not come into contact with each other in mixing hopper 1, it is not necessary to clean the inner wall of mixing hopper 1, thus achieving the purpose of cleaning-free operation.

[0037] Among them, such as Figure 4 As shown, the first fork 201 and the second fork 202 are provided with an included angle of at least 70° between the straight lines near the two ends of the fixed collar 103; this facilitates increasing the swing amplitude of the mixing hopper 1 and makes the mixing of the material in the mixing hopper 1 more uniform.

[0038] Among them, such as Figure 1 As shown, a connecting hole is provided on the inner side of the fixing collar 103 at a position corresponding to the connecting pin 204; this facilitates the connection pin 204 being sleeved on the fixing collar 103.

[0039] Among them, such as Figure 3 and Figure 5 As shown, the flexible hose 3 has external threads on the outer sides of both ends, and the first connector 1042 and the hollow shaft 5 have threaded connection grooves on the inner side corresponding to the external threads at the ends of the flexible hose 3; the flexible hose 3 is connected to the hollow shaft 5 and the first connector 1042 by threads; the threaded connection can ensure the sealing between the flexible hose 3, the hollow shaft 5 and the rotary joint 104, and prevent air leakage.

[0040] Working principle: When the mixer is mixing materials, the plastic bag is put into the inner hopper 105, the vacuum pump is started, and the plastic bag is pressed tightly against the inner wall of the inner hopper 105. Then the hopper cover 102 is closed, and the drive unit is started to make the drive shaft 6 rotate around the axis. The drive shaft 6 is rotatably connected to the second fork 202 by the pin 203, the second fork 202 is rotatably connected to the fixed collar 103 by the connecting pin 204, the first fork 201 is rotatably connected to another set of fixed collars 103, and the first fork 201 is rotatably connected to the hollow shaft 5. Therefore, when the drive shaft 6 rotates, the mixing hopper 1 will move regularly along the three axes, so that the raw materials in the mixing hopper 1 are mixed more thoroughly. After the mixing is completed, the plastic bag can be directly removed without washing.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
