Description

Technical Field

[0001] The utility model relates to the technical field of foamed silicone rubber, in particular to a mixing device for producing foamed silicone rubber. Background Art

[0002] Foamed silicone, also known as addition-type silicone, is composed of silicone and curing agent in a one-to-one ratio. It is white and becomes a soft elastic material after vulcanization. Foamed silicone products are a pure silicone material made by chemical foaming. After foaming, its pore size is small and fine and uniform. It is an environmentally friendly material. The products produced are non-toxic and odorless, safe and hygienic. It can be used to make flexible silicone rubber products such as human bodies, insoles, shoulder pads, patches, anti-slip mats, etc.

[0003] The production of foamed silicone rubber requires the use of a mixing device for mixing. By mixing the rubber and various additives together, the rubber is fully dispersed and evenly mixed to obtain an ideal rubber mixture. For example, the existing Chinese patent publication number CN214082236U discloses a mixing device for a foamed silicone rubber material production system. The device includes an L-shaped support, a kettle body is mounted on the top of the L-shaped support, a kettle cover is connected to the top of the kettle body, and a controller is fixed to the side wall of the kettle body. Vent interface pipes are mounted on both ends of the top of the kettle cover. A movable shaft is movably connected to the middle of the kettle body via a bearing. A stirring blade is mounted on the outer wall of the movable shaft. The end of the movable shaft extending to the outside of the kettle body passes through the L-shaped support and is connected to a motor. The utility model, through the coordination of a block, a support rod, a connecting rod, a sliding sleeve, and a spring, can cause the block to withdraw from the exhaust hole when the pressure exceeds the normal critical value, thereby facilitating the discharge of high-pressure gas. When the pressure returns to normal, the block is reinserted into the exhaust hole to block the exhaust hole. This is not only simple and efficient to operate, but also prevents injury to objects and workers, thereby improving safety.

[0004] However, the mixing equipment still has some shortcomings in actual use. For example, there is a lack of necessary shaking measures during the mixing process, and the mixing reaction is accelerated by only stirring the raw materials, which also leads to low mixing efficiency and insufficient mixing of foamed silica gel.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] like Figure 1-4 As shown, the utility model provides a technical solution: comprising a base assembly 1, a mixing assembly 2 is provided on the top of the base assembly 1, the base assembly 1 comprises a bottom plate 101, a linear motor 102 is fixedly mounted on the middle of the top surface of the bottom plate 101, a rotating concave plate 103 is fixedly mounted on the top surface of the slider of the linear motor 102, a rolling shaft 104 is rotatably mounted on the top of the rotating concave plate 103, mounting risers 107 are fixedly mounted on the middle of both side edges of the top surface of the bottom plate 101, and adapter shafts 108 are rotatably mounted on the top of the inner sides of the two mounting risers 107;

[0023] The mixing assembly 2 includes a mixing kettle body 201, a rotating motor 204 is fixedly mounted at the center of the front of the mixing kettle body 201, one end of the output shaft of the rotating motor 204 extends into the interior of the mixing kettle body 201, and a rotating shaft 205 is fixedly mounted at one end of the output shaft of the rotating motor 204. A toggle plate 207 is fixedly mounted on the bottom of the side of the mixing kettle body 201, and a toggle rolling groove 208 is formed on the bottom of one side of the toggle plate 207.

[0024] The mixing kettle body 201 is located between the two adapter shafts 108, and the middle sides of the side of the mixing kettle body 201 are fixedly connected to one end of the two adapter shafts 108 respectively. The rolling shaft 104 is rollingly installed in the toggle rolling groove 208. Under the action of the linear motor 102, the rotating concave plate 103 will move horizontally, and the movement of the rotating concave plate 103 will drive the rolling shaft 104 to move. Since the rolling shaft 104 is rollingly installed in the toggle rolling groove 208, controlling the reciprocating movement of the rolling shaft 104 will drive the toggle plate 207 to tilt back and forth. By tilting the toggle plate 207 back and forth, the two ends of the mixing kettle body 201 can be driven to tilt and shake back and forth, so that the raw materials in the mixing kettle body 201 can be mixed more evenly. Cooperating with the stirring blade 206, the mixing efficiency can be effectively improved, and it is more practical.

[0025] In this embodiment, stabilizing sliders 106 are fixedly installed on the top of both sides of the slider of the linear motor 102, and stabilizing grooves 105 are opened on both sides of the top surface of the base plate 101. The two stabilizing grooves 105 correspond one-to-one to the two stabilizing sliders 106, and the stabilizing sliders 106 are slidably installed in the stabilizing grooves 105 to improve the stability of the structure.

[0026] A feeding pipe 202 is provided on the top side of the internal mixing kettle body 201, and a discharge pipe 203 is provided on the bottom back side of the internal mixing kettle body 201. One end of the feeding pipe 202 and the discharge pipe 203 are both connected to the interior of the internal mixing kettle body 201. Raw materials can be conveniently added to the internal mixing kettle body 201 through the feeding pipe 202, and the reacted products can be conveniently discharged through the discharge pipe 203.

[0027] A plurality of stirring blades 206 are fixedly mounted on the shaft of the rotating shaft 205 at equal distances from one end to the other. The stirring blades 206 rotate to stir the raw materials in the mixing kettle 201, thereby improving the reaction efficiency of the raw materials.

[0028] During banburying, in order to improve the banburying efficiency, the rotating motor 204 can be started. Under the action of the rotating motor 204, the rotating shaft 205 and the stirring blade 206 rotate. The rotation of the stirring blade 206 can stir the raw materials in the banburying kettle body 201, thereby improving the reaction efficiency of the raw materials. At the same time, the linear motor 102 is started. Under the action of the linear motor 102, the rotating concave plate 103 will move horizontally. The movement of the rotating concave plate 103 will drive the rolling shaft 104 to move. Since the rolling shaft 104 is installed in a rolling manner in the toggle rolling groove 208, the reciprocating movement of the rolling shaft 104 will drive the toggle plate 207 to tilt back and forth. By tilting the toggle plate 207 back and forth, the two ends of the banburying kettle body 201 can be driven to tilt and shake back and forth, so that the raw materials in the banburying kettle body 201 can be mixed more evenly. Cooperating with the stirring blade 206, the banburying efficiency can be effectively improved, and it is more practical.

[0029] In summary, the foamed silicone rubber production mixing equipment can control the reciprocating movement of the rolling shaft 104 to move the toggle plate 207 back and forth. The toggle plate 207 can drive the two ends of the mixing kettle body 201 to tilt and shake back and forth, so that the raw materials in the mixing kettle body 201 can be mixed more evenly. Combined with the stirring blade 206, the mixing efficiency can be effectively improved, and the practicality is stronger.

[0030] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
