[0033] In order to further understand the content of the utility model, the utility model is described in detail in combination with the drawings and examples. It should be understood that the examples are merely used to explain the utility model and are not limited.

[0034] The following is a detailed description of the utility model in combination with the drawings and examples. Figures 1-7 The utility model is further described in detail.

[0035] As Figures 1-2As shown, a synthetic leather raw material mixer in this embodiment includes a mixing drum 100 and a drum cover 110. The drum cover 110 is provided with a mixing assembly, which includes a rotating shaft 210 rotatably disposed inside the mixing drum 100. The rotating shaft 210 is fitted with a lifting and lowering mixing shaft 220. The mixing shaft 220 is provided with a mixing rod 221. The rotating shaft 210 is provided with a driving component for driving the mixing shaft 220 to lift and lower. The drum cover 110 is provided with a hopper 120 whose lower end extends into the mixing drum 100. The inner wall of the drum cover 110 is provided with a clearing component. The rotation of the rotating shaft 210 is used to drive the clearing component to clear the hopper 120.

[0036] In this embodiment, during actual use, the mixing drum 100 has an open top, and the drum cover 110 is fixedly installed at the open top of the mixing drum 100. The drum cover 110 is also provided with a feeding port 111, so that when mixing artificial leather raw materials, plasticizers, solvents, pigments and other raw materials can be added into the mixing drum 100 through the feeding port 111. Powdered raw materials (polyurethane resin, PVC resin) are poured into the hopper 120 and added into the mixing drum 100 through the hopper 120. The mixing component stirs the raw materials in the mixing drum 100 to achieve mixing of multiple raw materials.

[0037] Specifically, in order to discharge the raw materials inside the mixing drum 100, a discharge pipe 101 is provided on the outer wall of the mixing drum 100 and at the bottom, wherein a switch valve for controlling the discharge is provided on the discharge pipe 101.

[0038] In this embodiment, combined with Figure 4 As shown, multiple sets of stirring rods 221 are distributed along the axial direction of the stirring shaft 220. The rotation of the rotating shaft 210 drives the stirring shaft 220 to rotate, thereby causing the stirring rods 221 to rotate and stir the raw materials in the stirring drum 100. The driving component allows the stirring shaft 220 to move up and down along the rotating shaft 210 during rotation, thereby changing the position of the multiple sets of stirring rods 221. This prevents the stirring rods 221 from only stirring in their horizontal position, making the stirring of the raw materials more uniform and resulting in a better mixing effect.

[0039] In this embodiment, combined with Figure 2 As shown, the lower end of the hopper 120 forms a feed pipe extending into the mixing drum 100. The diameter of the feed pipe is much smaller than the diameter of the hopper 120. In order to avoid blockage and affect the addition of raw materials from the hopper 120 into the mixing drum 100, in this embodiment, by setting up a dredging component, during actual use, when the rotating shaft 210 rotates and drives the mixing rod 221 to stir the raw materials, the dredging component is driven to dredge the hopper 120 so that the raw materials can be added into the mixing drum 100 more smoothly.

[0040] Specifically, the upper end opening of the hopper 120 is provided with a rotatable cover plate 121, wherein the outer side of the cover plate 121 is rotatably connected to the upper end opening of the hopper 120 by a hinge, so as to realize the rotary installation of the cover plate 121. When the cover plate 121 is rotatably lapped on the upper end opening of the hopper 120, it can shield the hopper 120, so as to prevent dust from entering the hopper 120.

[0041] In combination Figures 3-6 As shown in the drawings, in the embodiment, a sliding groove 401 is arranged on the inner wall of the stirring shaft 220 along the length direction thereof, and a sliding block 301 is arranged on the outer side wall of the rotating shaft 210 and slides in the sliding groove 401.

[0042] The driving member comprises an upper disc 230 fixedly arranged at the upper end portion of the rotating shaft 210 and a lower disc 240 fixedly arranged on the bottom wall of the stirring drum 100. The top wall of the lower disc 240 is provided with a first recess 601 along the circumferential direction thereof. One side wall of the first recess 601 is provided with a first guide surface 602. A first spring 250 for pushing the stirring shaft 220 downward is arranged on the rotating shaft 210 between the upper disc 230 and the stirring shaft 220. The lower end portion of the stirring shaft 220 is provided with a stopper 402 which can extend into the first recess 601. The stirring shaft 220 is rotatable to make the stopper 402 slide out of the first recess 601 along the first guide surface 602.

[0043] In the embodiment, the sliding groove 401 and the sliding block 301 are arranged to form a key groove cooperation between the stirring shaft 220 and the rotating shaft 210, that is, the rotating shaft 210 can drive the stirring shaft 220 to rotate, and at the same time, the stirring shaft 220 can be lifted along the rotating shaft 210, so as to improve the stirring effect of the stirring assembly.

[0044] In order to better realize the rotation of the rotating shaft 210, in the embodiment, the drum cover 110 is provided with a motor 130 for driving the rotating shaft 210 to rotate.

[0045] In actual use, the upper end of the rotating shaft 210 is rotatably installed on the drum cover 110 by a bearing. In order to stably install the rotating shaft 210 in the stirring drum 100, in the embodiment, the middle portion of the lower disc 240 is concave to form a rotating groove 603 for the lower end of the rotating shaft 210 to extend into, so that the motor 130 can stably drive the rotating shaft 210 to rotate in the stirring drum 100.

[0046] In this embodiment, the upper end of the first spring 250 abuts against the upper disk 230, and the lower end abuts against the upper end of the stirring shaft 220, so that the first spring 250 pushes the stirring shaft 220 downward, so that the push rod 402 abuts against the upper surface of the lower disk 240. The first groove 601 has a first guide surface 602 on one side wall and a vertical surface on the other side. When the rotating shaft 210 drives the stirring shaft 220 to rotate, it drives the push rod 402 to rotate. With the push of the first spring 250, when the push rod 402 slides into the first groove 601 along the vertical surface, the stirring shaft 220 descends. When the stirring shaft 220 continues to rotate, the push rod 402 can slide out of the first groove 601 along the first guide surface 602. Thus, the stirring shaft 220 can rise and fall along the rotating shaft 210 by continuously rotating, thereby improving the stirring effect of the stirring assembly.

[0047] In this embodiment, in order to better achieve the installation of the cylinder cover 110 at the upper opening of the mixing cylinder 100, a lower flange portion 611 is formed by extending outward from the upper opening of the mixing cylinder 100, and an upper flange portion 311 that cooperates with the lower flange portion 611 is formed by extending outward from the end of the cylinder cover 110. The lower flange portion 611 and the upper flange portion 311 are connected by bolts, so that the cylinder cover 110 can be installed at the upper opening of the mixing cylinder 100.

[0048] In this embodiment, the outer side wall of the upper disk 230 is provided with a second groove 501 along its circumference, and the two side walls of the second groove 501 form a second guide surface 502.

[0049] The unblocking assembly includes a mounting bracket 510, with an unblocking shaft 520 extending from both ends between the mounting brackets 510. One end of the unblocking shaft 520 is used to cooperate with the outer wall of the upper disc 230, and the other end extends into the hopper 120. A retaining ring 521 is provided on the unblocking shaft 520 located in the mounting bracket 510. A second spring 530 is sleeved on the unblocking shaft 520 to push the retaining ring 521 to move the unblocking shaft 520 to the upper disc 230. The rotating shaft 210 rotates to allow one end of the unblocking shaft 520 to slide out or slide into the second groove 501 along the second guide surface 502.

[0050] In this embodiment, combined with Figure 5 As shown, the mounting bracket 510 is formed by a base plate and side plates on both sides of the base plate. The base plate is fixed to the inner wall of the cylinder cover 110 by screws so that the mounting bracket 510 can be installed.

[0051] In actual use, the dredging shaft 520 is movably installed between the two side plates, one end of the second spring 530 abuts against the side plate, and the other end abuts against the blocking ring 521 to push one end of the dredging shaft 520 to abut against the outer circumferential wall of the upper disc 230, at this time, the other end of the dredging shaft 520 extends into the feeding pipe of the hopper 120, when the rotating shaft 210 drives the upper disc 230 to rotate, the one end of the dredging shaft 520 can slide into or out of the second groove 501 along the second guide surface 502, and the second spring 530 is used to realize the extension and retraction movement of the dredging shaft 520 between the two side plates, and then the other end of the dredging shaft 520 moves in the feeding pipe to realize the dredging of the hopper 120.

[0052] In combination Figure 7 As shown in the drawings, in the embodiment, the side wall of the mounting frame 510 is provided with a knocking rod 710 located on both sides of the hopper 120 and having one end hingedly connected to the mounting frame 510, the other end of the knocking rod 710 is provided with a knocking ball 711 for knocking the hopper 120, the knocking rod 710 is provided with a pulling rod 720 having one end hingedly connected to the knocking rod 710, the other end of the pulling rod 720 is hingedly connected to the dredging shaft 520, and the dredging shaft 520 moves to drive the pulling rod 720 to pull the knocking rod 710 to swing.

[0053] In the embodiment, the side wall of the mounting frame 510 close to the hopper 120 is provided with a first hinged seat, one end of the knocking rod 710 is hingedly connected to the corresponding first hinged seat to realize the hinged connection between the knocking rod 710 and the side wall of the mounting frame 510, the side wall of the dredging shaft 520 is provided with a second hinged seat, one end of the pulling rod 720 is hingedly connected to the side wall of the knocking rod 710 through a hinge shaft, and the other end is hingedly connected to the second hinged seat, so that in actual use, when the dredging shaft 520 moves to the feeding pipe of the hopper 120, the knocking rod 710 is pushed away from each other by the pulling rod 720, at this time, the knocking ball 711 is away from the feeding pipe, when the dredging shaft 520 moves away from the feeding pipe of the hopper 120, the knocking rod 710 is pulled to each other by the pulling rod 720, so that the knocking ball 711 knocks the feeding pipe to vibrate, so that the raw materials are discharged, that is, the knocking rod 710 can also swing when the dredging shaft 520 moves, and the knocking ball 711 knocks the feeding pipe to improve the dredging effect of the dredging assembly.
