Description

Technical Field

[0001] This utility model relates to the field of polyurethane technology, specifically to a polyurethane raw material reaction and dissolution device. Background Technology

[0002] Polyurethane is a versatile material used in the manufacture of thermal insulation materials, such as rigid and flexible polyurethane foam, for the insulation of walls, roofs, and floors. It is also used in building sealants, waterproof coatings, and flooring materials, providing excellent weather resistance and durability. Polyurethane is used as a filler, padding material, and coating material, such as for sofas, mattresses, chair armrests, and furniture surface coatings. It is also used in the manufacture of insulating and sealing materials, such as in varnishes and fiber optic cables, and as an adhesive in audio tapes, video tapes, and computer disks.

[0003] A search revealed that in a polyurethane resin production dissolving tank with patent publication number CN222400985U, it was proposed that "this utility model uses a set annular block plate, and a fixed column drives the annular block plate to make a circular motion. The sliding of the slide plate up and down drives the annular block plate to slide up and down, so that the annular block plate cleans the polyurethane resin raw material inside the tank and prevents waste."

[0004] However, the above solution still has some shortcomings in actual use. In this technical solution, polyurethane raw materials can only be mixed vertically during operation, which greatly reduces the reaction and dissolution effect of polyurethane raw materials with other materials, thus affecting the subsequent processing quality.

Detailed Implementation

[0023] 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.

[0024] Please see Figure 1-6 This utility model discloses a polyurethane raw material reaction and dissolution device, including a mounting frame 1, an adjustment structure 3 fixed on the back side of the mounting frame 1, and a mixing device 2 fixedly connected to the movable end of the adjustment structure 3.

[0025] The adjustment structure 3 includes a manual gear 301 and a locking mechanism 302. The manual gear 301 passes through the mounting plate of the mounting frame 1 and is fixedly connected to the outside of the mixing device 2. The locking mechanism 302 is fixedly connected to the mounting plate of the mounting frame 1 and is located above the manual gear 301.

[0026] The locking mechanism 302 includes a drive box 303, a top cover 304 is movably engaged at the top of the drive box 303, a displacement rack 305 is slidably connected inside the drive box 303, the displacement rack 305 meshes with a hand-operated gear 301, a movable pin 306 is rotatably connected inside the drive box 303, an extension plate 307 is fixedly installed on the outside of the movable pin 306, a push rod 308 is fixedly connected at the top of the extension plate 307, and the push rod 308 extends above the top cover 304.

[0027] By setting the adjustment structure 3, the mixing device 2 can be rotated by the hand-operated gear 301. Combined with the locking mechanism 302, the rotated mixing device 2 can be locked, enabling effective horizontal and vertical mixing of the raw materials. This significantly improves the reaction and dissolution effect of the polyurethane raw materials, ensuring uniform dispersion and reaction during the chemical reaction. Through this mixing process, the uniformity of the polyurethane raw materials mixed with other materials is enhanced, thereby guaranteeing the quality of subsequent processing.

[0028] Specifically, the mixing device 2 includes a mixing box 201, a closing cover 202 is movably snapped onto the opening of the mixing box 201, a discharge valve 203 is fixedly installed at the bottom of the mixing box 201, an external motor 204 is fixedly connected to the outside of the mixing box 201, a rotating shaft 205 is fixedly installed on the output shaft of the external motor 204, the rotating shaft 205 is located inside the mixing box 201, and a rotating arc plate 206 is fixedly sleeved on the surface of the rotating shaft 205.

[0029] In this embodiment, when the external motor 204 is started, it can drive the rotating shaft 205 and the rotating arc plate 206 to rotate inside the mixing box 201, thereby mixing the polyurethane raw materials and improving the reaction and dissolution efficiency of the raw materials.

[0030] Specifically, the mixing box 201 has two bearing plates 207 on its outer side, and the rotating shaft 205 is located between the two bearing plates 207.

[0031] In this embodiment, the two bearing plates 207 can limit the rotation of the shaft 205, so that the shaft 205 will not deviate or wobble during rotation, thus ensuring the stability of the mixed operation.

[0032] Specifically, the maximum lifting height of the displacement rack 305 is at the same height as the top of the movable pin 306, and the minimum lowering height of the displacement rack 305 is at the same height as the bottom of the movable pin 306.

[0033] In this embodiment, the height settings of the displacement rack 305 and the movable pin 306 ensure that the displacement rack 305 can effectively cooperate with the movable pin 306 during the sliding process to achieve the locking and unlocking functions.

[0034] When it is necessary to lock the mixing device 2, the displacement rack 305 is pushed to the lowest position and contacts the bottom end of the movable pin 306, thereby preventing the rotation of the hand-operated gear 301 and achieving the locking effect.

[0035] Conversely, when unlocking is required, the displacement rack 305 is pulled to its highest position and engages with the top of the movable pin 306. At this time, the hand-operated gear 301 can rotate freely, thereby adjusting the angle of the mixing device 2.

[0036] Specifically, the push rod 308 is located diagonally above the displacement rack 305, and the top cover 304 has an arc groove inside, with the push rod 308 located inside the arc groove.

[0037] In this embodiment, the push rod 308 is designed to facilitate movement by external force. During movement, the push rod 308 drives the extension plate 307 and the movable pin 306 to rotate. During rotation, the movable pin 306 can lock or unlock the displacement rack 305 by contacting or separating from it. This design allows operators to easily control the locking state of the mixing device 2, thereby adjusting and fixing its angle to meet different mixing needs.

[0038] In use, first open the sealing cover 202, pour the raw materials into the mixing box 201, and then close the sealing cover 202. Next, start the external motor 204, which drives the rotating shaft 205 and the rotating arc plate 206 to rotate inside the mixing box 201, thus mixing the raw materials laterally.

[0039] When vertical mixing of polyurethane raw materials is required, the push rod 308 is moved, causing it to slide inside the arc groove and push the extension plate 307 and the movable pin 306 to move. During the movement, the movable pin 306 gradually moves away from the displacement rack 305, allowing the displacement rack 305 to move up and down. This releases the displacement rack 305 from the hand-operated gear 301. Then, the hand-operated gear 301 is rotated, causing the mixing box 201 to deflect at an angle. This allows the polyurethane raw materials in the mixing box 201 to achieve vertical mixing under the action of gravity and the rotating arc plate 206.

[0040] After adjusting to the appropriate angle, press down the displacement rack 305 again. When the displacement rack 305 is at its lowest position, rotate the push rod 308 to return the extension plate 307 and the movable pin 306 to their original positions. This causes the bottom end of the movable pin 306 to re-contact the top end of the displacement rack 305, locking the displacement rack 305. Consequently, the hand-operated gear 301 is locked, and the angle of the mixing box 201 is fixed, ensuring the stability of vertical mixing.

[0041] In summary, this polyurethane raw material reaction and dissolution device, through the setting of the adjustment structure 3, allows the mixing device 2 to be rotated by a hand-operated gear 301, and the locking mechanism 302 can lock the rotated mixing device 2, enabling effective horizontal and vertical mixing of the raw materials. This significantly improves the reaction and dissolution effect of the polyurethane raw materials, ensuring that the raw materials are uniformly dispersed and reacted in the chemical reaction. Through this mixing process, the uniformity of the polyurethane raw materials mixed with other materials is enhanced, thereby ensuring the quality of subsequent processing.

[0042] It should be noted that the specific model and specifications of the external motor 204 and the feed valve 203 in the polyurethane raw material reaction and dissolution device need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail.

[0043] Furthermore, the power supply and operating principle of the external motor 204 and the feed valve 203 in the polyurethane raw material reaction and dissolution device are clear to those skilled in the art and will not be described in detail here.

[0044] Furthermore, the working principle and wiring method of the external motor 204 and the feeding valve 203 in the polyurethane raw material reaction and dissolution device are commonplace and belong to conventional methods or common knowledge. They will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

[0045] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
