Description

Technical Field

[0001] This invention relates to the fields of mixing, such as dissolving, emulsifying, and dispersing, and particularly to an automated mixing apparatus for sponge production. Background Technology

[0002] Polyurethane foam is mainly made by mixing and foaming organic isocyanate, polyether polyol, catalyst, foam stabilizer, external foaming agent and water. The foaming technology of the sponge uses chemical reaction to create a porous sponge material. The sponge is composed of polymer base material and foaming agent. The foaming agent releases gas in the chemical reaction, thereby turning the polymer base material into a porous solid. The mixing device mixes the polyurethane foam raw materials and heats the raw materials. After mixing, the raw materials are discharged into the foaming mold for molding. The technical inspiration for the mixing device is as follows:

[0003] The study of mixing devices revealed the following problems:

[0004] The mixing device needs to add the catalyst during the mixing process. However, the mixing device usually adds the catalyst manually in batches or at one time, which requires a long time to fully mix the catalyst and the sponge raw material. This makes it impossible for the mixing device to add the catalyst quickly during the stirring process.

[0005] After the mixing device has finished mixing, the sponge raw material is transported through the pipeline. However, the sponge raw material tends to stick to the inner wall of the pipeline after being transported. The sponge raw material solidifies after cooling, which can cause blockages on the inner wall of the pipeline after long-term use.

[0006] Currently, the mixing mechanism of the dye color matching system for high thermal stability automotive polyurethane foam disclosed in CN201910297804.5 discloses a mixing mechanism. The other end of the stirring shaft of this invention is connected to the support bearing set at the bottom of the mixing tank. Both sides of the stirring shaft are fixed with stirring blades. Each stirring blade is provided with a branch air channel. The branch air channel is connected to the air injection chamber. Air nozzles are evenly installed on the stirring blades and are connected to the branch air channels. At the same time, air is injected into the interior of the mixing tank through the air injection chamber, branch air channels and air nozzles to achieve dye tumbling and improve the mixing effect.

[0007] The present invention mainly solves the problem that the mixing device cannot quickly add the catalyst during the stirring process. Summary of the Invention

[0008] To address the aforementioned technical problems, the present invention provides an automatic mixing device for sponge production, thereby resolving the issues described in the background section.

[0009] The purpose and effectiveness of the automatic mixing device for sponge production of the present invention are achieved by the following specific technical means: The automatic mixing device for sponge production includes a mixing tank, a motor is provided at the upper end of the mixing tank, a stirring shaft rotates at the lower end of the motor, a pipe runs through one side of the lower end of the mixing tank, a suction pump runs through one end of the pipe, and a sealing cover is hinged to the upper end of the mixing tank.

[0010] Furthermore, the inner wall of the mixing tank is surrounded by heating wires, and the heating wires, motor and suction pump are all connected to the power circuit through power lines. The raw materials enter the interior of the mixing tank through the sealed cover.

[0011] Furthermore, the stirring shaft rotates inside the mixing tank, and a feeding mechanism is provided on the outer side of the upper end of the stirring shaft.

[0012] Furthermore, the pipe is L-shaped, with the outlet located on one side of the upper end of the pipe and the suction pump located at the bend of the pipe.

[0013] Furthermore, the feeding mechanism includes a material bucket, a discharge pipe, a baffle, a slider, and a protrusion. The material bucket is installed at the upper end of the outside of the stirring shaft, the discharge pipe passes through both sides of the lower end of the material bucket, the baffle slides on both sides of the inner wall of the material bucket, the slider is located at one end of the baffle, and the protrusion slides at the upper end of the slider.

[0014] Furthermore, the lower end of the inner wall of the material barrel is provided with sliding grooves on both sides. The sliding grooves are arranged horizontally and are located on both sides of one end of the discharge pipe. The slider slides horizontally inside the sliding grooves.

[0015] Furthermore, the discharge pipe is arranged horizontally, with an internal diameter of 0.5-1cm, and one end of the discharge pipe is slidably attached to the baffle.

[0016] Furthermore, the baffle is semi-circular with an angle of 180°. The baffles are arranged in pairs, and the side of the baffle away from the discharge pipe is inclined at 15-35°.

[0017] Furthermore, the upper end of the slider is provided with a groove, which is inclined at 5-15°. The higher side of the groove is closer to the side of the baffle, and the protrusion is located inside the groove of the slider.

[0018] Furthermore, a support is surrounded on the outer side of the lower end of the stirring shaft, and spacers are surrounded on the four sides of the support. A rotating frame is rotatably fitted on the outer side of the support near the spacers.

[0019] Furthermore, the bracket is arranged in a cross shape, with multiple sets of spacer rings and rotating frames provided on the four sides of the bracket.

[0020] Furthermore, the spacer ring is circular in shape, and multiple spacer rings are arranged in a row. Each spacer ring is connected to a rotating frame. The middle part of the rotating frame is circular in shape, the upper end of the rotating frame is inclined at 25-45°, and the rotating frames are arranged vertically.

[0021] Furthermore, guide rails are provided on both sides of the inner wall of the pipe, a sliding ring slides through the inner side of the guide rails, a scraper ring slides at the lower end of the sliding ring, a connecting rod is provided on the inner side of the sliding ring, and a guide block is provided at the connecting end of the connecting rod.

[0022] Furthermore, the guide rails are arranged vertically and are laterally concave, with the sliding ring and scraper ring sliding vertically inside the guide rails.

[0023] Furthermore, both the scraper ring and the sliding ring are circular, with the outer wall of the scraper ring slidingly attached to the inner wall of the pipe, and the lower end of the scraper ring inclined at 15-35°.

[0024] Furthermore, the upper end of the guide block is conical, the lower end of the guide block is horizontal, the guide block is located in the middle of the inside of the pipe, and the guide block is connected to the sliding ring through a connecting rod.

[0025] Beneficial effects:

[0026] 1. Fill the inside of the material tank with catalyst, with baffles in pairs. At this time, the baffles are attached to one side of the discharge pipe, which can form a seal on one end of the discharge pipe.

[0027] 2. The motor drives the stirring shaft to rotate, and the material bucket rotates synchronously. Since the baffles are arranged in pairs, the side of the baffle away from the discharge pipe is inclined at 15-35°, so there is a gap between each set of baffles. Therefore, the catalyst inside the material bucket can impact the inner side of the gap of the baffles. The baffles can slide horizontally on the inner wall of the material bucket through the slider. Therefore, the baffles can slide horizontally on the inner wall of the material bucket by utilizing the centrifugal force generated when the stirring shaft rotates.

[0028] 3. The higher side of the groove is closer to the baffle, and the protrusion is located inside the groove of the slider. This allows the protrusion to be positioned on the side of the baffle away from the baffle. By using the protrusion, the center of gravity of the slider is oriented towards the side away from the baffle, which helps the baffle slide quickly against the inner wall of the barrel. The catalyst is added to the inside of the mixing tank through the discharge pipe. As the stirring shaft continues to rotate, the catalyst gradually falls into the inside of the mixing tank. This allows the mixing device to gradually add the catalyst during the mixing process, avoiding the need for manual addition of the catalyst once in the future, which would lead to incomplete mixing of the sponge raw material and the catalyst inside the mixing device, resulting in incomplete catalysis of the sponge raw material.

[0029] 4. The support is located below the material tank. When the stirring shaft rotates, the support rotates synchronously. The middle part of the rotating frame is circular. Therefore, by utilizing the centrifugal force generated when the support rotates, the rotating frame can rotate vertically 360° on the outside of the support, so that the stirring shaft rotates horizontally and the rotating frame can rotate vertically, thereby enabling rapid mixing of the catalyst and sponge raw materials added inside the mixing tank.

[0030] 5. The suction pump drives the sponge material into the pipeline. The lower end of the guide block is horizontal. When the sponge material flows upward, it can impact the lower end of the guide block. The lower end of the scraper ring is inclined at 15-35°, which can increase the contact area between the sponge material and the lower end of the scraper ring. This allows the sliding ring and the scraper ring as a whole to slide to the upper end of the guide rail when the sponge material enters the pipeline.

[0031] 6. When the suction pump stops working, the sliding ring and scraper ring can slide downwards using their own weight. The outer wall of the scraper ring slides and fits against the inner wall of the pipe, allowing the scraper ring to clean the inner wall of the pipe during the downward sliding process. This prevents the sponge material from adhering to the inner wall of the pipe, enabling this mixing device to achieve a rapid cleaning effect when the pipe stops conveying.

Detailed Implementation

[0044] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0045] Example:

[0046] As attached Figure 1 To be continued Figure 10 As shown:

[0047] Example 1: An automatic mixing device for sponge production includes a mixing tank 1, a motor 101 at the upper end of the mixing tank 1, a stirring shaft 104 rotating at the lower end of the motor 101, a pipe 103 passing through one side of the lower end of the mixing tank 1, a suction pump 102 passing through one end of the pipe 103, and a sealing cover 105 hinged to the upper end of the mixing tank 1.

[0048] Among them: mixing tank 1 and sealing cover 105, the inner wall of mixing tank 1 is surrounded by heating wire, the heating wire, motor 101 and suction pump 102 are all connected to the power circuit through power line, and the raw material enters the interior of mixing tank 1 through sealing cover 105.

[0049] The sealing cover 105 is hinged to the upper end of the mixing tank 1 by a hinge, and the sealing cover 105 swings at 90° at the upper end of the mixing tank 1.

[0050] The inner wall of the mixing tank 1 is surrounded by heating wires, which can heat the sponge raw material inside the mixing tank 1.

[0051] A stirring shaft 104 rotates inside the mixing tank 1, and a feeding mechanism is provided on the outer side of the upper end of the stirring shaft 104;

[0052] Pipeline 103 and suction pump 102, pipeline 103 is L-shaped, the outlet of pipeline 103 is located on one side of the upper end of pipeline 103, and suction pump 102 is located at the bend of pipeline 103.

[0053] The suction pump 102 is located at the bend in the pipeline 103; please refer to the instruction manual appendix. Figure 1 As shown;

[0054] Wherein: the sealing cover 105 is hinged to the upper end of the mixing tank 1, and the sealing cover 105 swings at 90° at the upper end of the mixing tank 1, so that the raw materials can enter the interior of the mixing tank 1 in sequence. The motor 101 drives the stirring shaft 104 to rotate, and the stirring shaft 104 can mix the sponge raw materials. The inner wall of the mixing tank 1 is surrounded by heating wires, which can heat the sponge raw materials inside the mixing tank 1. After the mixing is completed, the suction pump 102 is turned on, and the suction pump 102 draws the mixed raw materials to the outside of the mixing tank 1 through the pipe 103.

[0055] Example 2: Refer to the attached instruction manual Figure 1-5 It can be seen that the difference between Embodiment 2 and Embodiment 1 is that the feeding mechanism includes a material barrel 2, a discharge pipe 201, a baffle 202, a slider 203 and a protrusion 204. The material barrel 2 is installed on the upper end of the outside of the stirring shaft 104, the discharge pipe 201 passes through both sides of the lower end of the material barrel 2, the baffle 202 slides on both sides of the inner wall of the material barrel 2, the slider 203 is located at one end of the baffle 202, and the protrusion 204 slides on the upper end of the slider 203.

[0056] Among them: material barrel 2, the lower end of the inner wall of material barrel 2 is provided with sliding grooves on both sides, the sliding grooves are arranged horizontally, the sliding grooves are located on both sides of one end of the discharge pipe 201, and the slider 203 slides horizontally inside the sliding grooves.

[0057] The interior of the material barrel 2 is filled with catalyst. The catalyst is used for sponge processing and is prepared from metals or oxides, carbonaceous materials, polymers and other substances.

[0058] The lower inner wall of the material barrel 2 has horizontally arranged grooves on both sides. The grooves are located on both sides of one end of the discharge pipe 201. Please refer to the instruction manual for details. Figure 4 As shown;

[0059] The discharge pipe 201 is arranged horizontally, and the inner diameter of the discharge pipe 201 is 0.5-1cm. One end of the discharge pipe 201 is slidably attached to the baffle 202.

[0060] The inner diameter of the discharge pipe 201 is 0.5-1cm. By limiting the inner diameter of the discharge pipe 201, the amount of catalyst discharged can be limited, preventing the catalyst from falling rapidly into the mixing tank 1.

[0061] Baffle 202 is semi-circular in shape with a semi-circular angle of 180°. Baffles 202 are arranged in pairs. The side of baffle 202 away from the discharge pipe 201 is inclined at 15-35°.

[0062] The baffles 202 are arranged in pairs, with the side of the baffle 202 away from the discharge pipe 201 inclined at 15-35°, so that there is a gap between each group of baffles 202. Please refer to the instruction manual. Figure 5 As shown;

[0063] The baffle 202 is semi-circular with a semi-circular angle of 180°. Therefore, when the baffle 202 is attached to one side of the discharge pipe 201, the baffle 202 can form a seal on one side of the discharge pipe 201.

[0064] The slider 203 and the protrusion 204 are provided. The upper end of the slider 203 is provided with a groove, which is inclined at 5-15°. The higher side of the groove is close to the side of the baffle 202. The protrusion 204 is located inside the groove of the slider 203.

[0065] The higher side of the groove is closer to the baffle 202, and the protrusion 204 is located inside the groove of the slider 203, so that the protrusion 204 can be located on the side of the baffle 202 away from the baffle 202.

[0066] Wherein: the catalyst is filled into the inside of the material barrel 2, and the baffles 202 are arranged in pairs. At this time, the baffles 202 are attached to one side of the discharge pipe 201, and the baffles 202 can be used to seal one end of the discharge pipe 201.

[0067] Motor 101 drives stirring shaft 104 to rotate, and material barrel 2 rotates synchronously. Since baffles 202 are arranged in pairs, the side of baffle 202 away from discharge pipe 201 is inclined at 15-35°, so there is a gap between each group of baffles 202. Therefore, the catalyst inside material barrel 2 can impact the inner side of the gap of baffle 202. Baffle 202 can slide horizontally on the inner wall of material barrel 2 through slider 203. Therefore, baffle 202 can slide horizontally on the inner wall of material barrel 2 by the centrifugal force generated when stirring shaft 104 rotates.

[0068] The higher side of the groove is closer to the baffle 202, and the protrusion 204 is located inside the groove of the slider 203. This allows the protrusion 204 to be positioned on the side of the baffle 202 away from the baffle 202. By using the protrusion 204, the center of gravity of the slider 203 is oriented towards the side away from the baffle 202, which helps the baffle 202 to slide quickly on the inner wall of the material barrel 2. The catalyst is added to the inside of the mixing tank 1 through the discharge pipe 201. As the stirring shaft 104 continues to rotate, the catalyst gradually falls into the inside of the mixing tank 1. This allows the mixing device to gradually add the catalyst during the mixing process, avoiding the need for manual addition of the catalyst once in the future, which would lead to incomplete mixing of the sponge raw material and the catalyst inside the mixing device and incomplete catalysis of the sponge raw material.

[0069] Example 3: Refer to the attached instruction manual Figure 2 and 6It can be seen that the difference between Example 3 and Examples 1 and 2 is that the outer side of the lower end of the stirring shaft 104 is surrounded by a support 3, the four sides of the support 3 are surrounded by partition rings 301, and the outer side of the support 3 near the partition rings 301 is rotatably fitted with a rotating frame 302.

[0070] Among them: support 3, the support 3 is arranged in a cross shape, and the spacer ring 301 and the rotating frame 302 are equipped with multiple sets on the four sides of the support 3;

[0071] The support bracket 3 is arranged in a cross shape. Multiple sets of spacer rings 301 and rotating brackets 302 are provided on the four sides of the support bracket 3. (See the attached instruction manual for details.) Figure 6 As shown;

[0072] The spacer ring 301 and the rotating frame 302 are arranged in a circular shape. Multiple spacer rings 301 are arranged in a circular shape. A rotating frame 302 is rotated between each spacer ring 301. The middle part of the rotating frame 302 is circular. The upper end of the rotating frame 302 is inclined at 25-45°. The rotating frames 302 are arranged vertically.

[0073] The center of the rotating frame 302 is annular, facilitating 360° vertical rotation of the rotating frame 3 on the outside of the support 3. The upper end of the rotating frame 302 is inclined at 25-45°, and the rotating frames 302 are arranged vertically. Please refer to the instruction manual appendix. Figure 6 As shown

[0074] Wherein: the support 3 is located below the material tank 2. When the stirring shaft 104 rotates, the support 3 rotates synchronously. The middle part of the rotating frame 302 is in the shape of a ring. Therefore, by utilizing the centrifugal force generated when the support 3 rotates, the rotating frame 302 can rotate vertically 360° on the outside of the support 3, so that the stirring shaft 104 rotates horizontally and the rotating frame 302 can rotate vertically, thereby enabling the rapid mixing of the catalyst and sponge raw materials added inside the mixing tank 1.

[0075] Example 4: Refer to the appendix of the instruction manual Figure 7-10 It can be seen that the difference between Embodiment 4 and Embodiments 1-3 is that guide rails 4 are provided on both sides of the inner wall of the pipe 103, a sliding ring 401 is slidably passed through the inner side of the guide rail 4, a scraper ring 402 is slidably provided at the lower end of the sliding ring 401, a connecting rod 403 is provided on the inner side of the sliding ring 401, and a guide block 404 is provided at the connecting end of the connecting rod 403.

[0076] Among them: guide rail 4, the guide rail 4 is arranged vertically, the guide rail 4 is concave horizontally, and the sliding ring 401 and scraper ring 402 slide vertically inside the guide rail 4;

[0077] The guide rails 4 are arranged vertically, so the sliding ring 401 and the scraper ring 402 slide vertically inside the guide rails 4;

[0078] The guide rail 4 is laterally concave, which allows the guide rail 4 to conveniently limit the sliding direction of the sliding ring 401;

[0079] The sliding ring 401 and the scraper ring 402 are both circular. The outer wall of the scraper ring 402 slides against the inner wall of the pipe 103. The lower end of the scraper ring 402 is inclined at 15-35°.

[0080] The lower end of the scraper ring 402 is inclined at 15-35°, which can increase the contact area between the sponge material and the lower end of the scraper ring 402.

[0081] The connecting rod 403 and the guide block 404 are connected in the middle of the pipe 103. The upper end of the guide block 404 is conical and the lower end is horizontal. The guide block 404 is connected to the sliding ring 401 through the connecting rod 403.

[0082] The upper end of the guide block 404 is conical, which can prevent the sponge material from stagnating at the upper end of the guide block 404. The lower end of the guide block 404 is horizontal, so that when the sponge material flows upward, it can impact the lower end of the guide block 404.

[0083] Wherein: the suction pump 102 drives the sponge material into the pipe 103. The lower end of the guide block 404 is horizontal. When the sponge material flows upward, it can impact the lower end of the guide block 404. The lower end of the scraper ring 402 is inclined at 15-35°, which can increase the contact area between the sponge material and the lower end of the scraper ring 402. When the sponge material enters the pipe 103, the sliding ring 401 and the scraper ring 402 can slide to the upper end of the guide rail 4.

[0084] When the suction pump 102 stops working, the sliding ring 401 and the scraper ring 402 can slide downwards using their own weight. The outer wall of the scraper ring 402 slides and fits against the inner wall of the pipe 103, so that the scraper ring 402 can scrape the inner wall of the pipe 103 during the downward sliding process, preventing the sponge material from adhering to the inner wall of the pipe 103. This allows the mixing device to achieve a rapid scraping effect when the pipe 103 stops conveying.
