[0028] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0029] Reference Figure 1-4 This utility model discloses a synthetic leather foaming device for mixing raw materials, comprising a fixed platform 1, a support rod 2 fixedly connected to the top of the fixed platform 1, a connecting frame 3 fixedly connected to the upper end of the support rod 2, a stirring device 4 arranged above the connecting frame 3, storage devices 5 arranged on the left and right sides above the stirring device 4, an auxiliary device 6 arranged in the middle of the upper part of the stirring device 4, a collection frame 7 arranged in front of the fixed platform 1, the collection frame 7 being slidably connected to the fixed platform 1, a handle 8 fixedly connected to the front of the collection frame 7, and casters 9 fixedly connected to the four lower corners of the collection frame 7. The stirring device 4 includes a stirring rod 43 for stirring the raw materials, the storage device 5 includes a scale 54 for marking the amount of material to be fed, and the auxiliary device 6 includes a piston 66 for assisting in the extrusion of the stirred raw materials.

[0030] The above structure, by setting up a collection frame 7, enables the collection and transfer of the foamed liquid synthetic leather. A handle 8 is fixedly connected to the front of the collection frame 7, and casters 9 are fixedly connected to the four lower corners of the collection frame 7, so that the operator can hold the handle 8 and pull the collection frame 7 to move it, thereby facilitating the transfer of the liquid synthetic leather.

[0031] The stirring device 4 includes a chamber 41. A first motor 42 is fixedly connected to the lower part of the chamber 41. A stirring rod 43 is fixedly connected to the output end of the first motor 42. A stabilizing frame 44 is fixedly connected inside the chamber 41. A transfer pump 45 is installed on the upper left and right sides of the chamber 41. A one-way air inlet valve 46 is installed on the left side of the chamber 41. A controllable pressure relief valve 47 is installed on the right side of the chamber 41. A discharge pipe 48 is fixedly connected to the lower part of the chamber 41. A plug 49 is inserted into the discharge pipe 48. An opening 410 is opened below the plug 49. An air inlet 411 is opened on the upper part of the chamber 41. The chamber 41 is located above the connecting frame 3 and is fixedly connected to the connecting frame 3. The stirring rod 43 is rotatably connected to the stabilizing frame 44. The output end of the transfer pump 45 is connected to the interior of the chamber 41.

[0032] The aforementioned structure, driven by the first motor 42, causes the stirring rod 43 to rotate, which in turn causes the raw materials and additives of the synthetic leather to be uniformly mixed together. A one-way air inlet valve 46 allows the operator to inject air into the chamber 41 using an air pump. This air, under the agitation of the rapidly rotating stirring rod 43, enters the liquid synthetic leather, thus completing the mechanical foaming of the liquid synthetic leather.

[0033] By providing a transfer pump 45, with the input end of the housing 51 connected to the transfer pump 45 and the output end of the transfer pump 45 connected to the interior of the housing 41, the operator can use the transfer pump 45 to add the liquid synthetic leather raw materials and liquid additives from the upper left and right sides of the housing 51 into the interior of the housing 41.

[0034] By providing a controllable pressure relief valve 47, when the operator injects air into the chamber 41, the controllable pressure relief valve 47 opens the valve. When the air pressure generated by the injected air exceeds a predetermined value, the controllable pressure relief valve 47 discharges the excess gas into the chamber 41, thereby ensuring that the air pressure inside the chamber 41 remains at a certain value and does not become too high while air is being injected.

[0035] By providing a stopper 49 with an opening 410 at its bottom, and by inserting the stopper 49 into the feed pipe 48 with the two in close contact, the operator can use a rope to pass through the opening 410. After the liquid synthetic leather inside the chamber 41 has finished foaming, the controllable pressure relief valve 47 is closed. Under the action of the piston 66 moving downward, the gas inside the chamber 41 pushes the liquid synthetic leather downward. At this time, the stopper 49 enters the collection frame 7 under the pushing action of the liquid synthetic leather. The operator can then use the rope to retrieve the stopper 49. With the piston 66 continuing to push, the liquid synthetic leather enters the collection frame 7.

[0036] The storage device 5 includes a housing 51, a cover 52 threadedly connected to the top of the housing 51, an observation window 53 installed at the front of the housing 51, a scale 54 fixedly connected to the right front of the housing 51, a sliding frame 55 fixedly connected to the left front of the housing 51, a slider 56 slidably connected inside the sliding frame 55, an auxiliary spring 57 fixedly connected to the front of the slider 56, a locking bolt 58 threadedly connected to the front of the slider 56, the housing 51 is fixedly connected to the compartment 41, and the housing 51 is connected to the input end of the transfer pump 45.

[0037] The aforementioned structure, with a slider 56 aligned with the scale 54, allows the operator to slide the slider 56 and tighten the locking bolt 58, bringing the slider 56 to the top of the internal material liquid level. Then, the transfer pump 45 adds material into the chamber 41. By observing the scale 54, the transfer pump 45 is turned off once the liquid level drops to a specified value. This provides a reference for the material addition process, allowing the operator to add material more accurately.

[0038] The auxiliary device 6 includes a frame 61. A second motor 62 is fixedly connected to the upper part of the frame 61. A lifting screw 63 is fixedly connected to the output end of the second motor 62. A lifting block 64 is threadedly connected to the upper part of the lifting screw 63. A lifting rod 65 is fixedly connected to the lower part of the lifting block 64. A piston 66 is fixedly connected to the lower part of the lifting rod 65. The piston 66 is located inside the chamber 41 and is in close contact with the inner wall of the chamber 41. The piston 66 is slidably connected to the chamber 41. The frame 61 is fixedly connected to the chamber 41.

[0039] The above structure, driven by the second motor 62, causes the lifting screw 63 to rotate. The upper part of the lifting screw 63 is threadedly connected to the lifting block 64, so that the lifting screw 63 drives the lifting block 64 to move up and down inside the frame 61. The lower part of the lifting block 64 is fixedly connected to the lifting rod 65, and the lower part of the lifting rod 65 is fixedly connected to the piston 66, so that the lifting block 64 drives the lifting rod 65 and the piston 66 to move up and down synchronously.

[0040] Working principle: When using this synthetic leather foaming device, the raw materials for synthetic leather are first poured into the left chamber 51, and the additives are poured into the right chamber 51. The transfer pump 45 is controlled to add materials of different masses to the chamber 41 in proportion. Then, the switch of the first motor 42 is turned on, and the stirring rod 43 stirs the two materials. After the controllable pressure relief valve 47 is opened, the chamber 41 is filled with air by the external air pump. Under the subsequent stirring action, the gas enters the interior of the liquid synthetic leather, thus completing the foaming operation of the liquid synthetic leather. Finally, the second motor 62 is turned on, and the piston 66 moves downward, transferring the foamed liquid synthetic leather into the collection frame 7, thus completing the foaming operation of the liquid synthetic leather.

[0041] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
