DETAILED DESCRIPTION
[0023] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.
[0024] Embodiment 1: A door and window sealing strip mixer that is easy to add materials, such as Figure 1 , Figure 2 and Figure 3 As shown, it includes a base plate 1, a vertical plate 2, a working box 3, a large motor 4, a sealing box 5, a cylinder 6, a lower pressure plate 601, a feeding frame 7, a small motor 8 and a spiral conveying shaft 9. The upper part of the base plate 1 is fixedly connected to the vertical plate 2, the working box 3 is fixedly connected to the bottom plate 1, the upper left part of the working box 3 is fixedly connected to the large motor 4, the upper side of the working box 3 is connected to the sealing box 5, the middle position of the upper part of the vertical plate 2 is fixedly connected to the cylinder 6, the telescopic end of the cylinder 6 is fixedly connected to the lower pressure plate 601, the lower pressure plate 601 is located in the sealing box 5, the front side of the sealing box 5 is connected to the feeding frame 7, the feeding frame 7 is an inclined structure with a high front and a low rear, which is convenient for pouring raw materials into the feeding frame 7, the front side of the feeding frame 7 is fixedly connected to a left-right symmetrical small motor 8, the left and right parts of the feeding frame 7 are rotatably connected to the spiral conveying shaft 9, and the spiral conveying shaft 9 is connected to the extended end of the adjacent small motor 8.
[0025] When using the device, the staff drives the lower pressure plate 601 to lift up through the cylinder 6, and then pours the raw materials into the loading frame 7, and then starts the small motor 8. The output shaft of the small motor 8 rotates to drive the spiral conveyor shaft 9 to rotate. The spiral conveyor shaft 9 rotates to add the raw materials to the sealed box 5 and the working box 3 at a uniform speed and in a uniform amount. After adding a certain amount of raw materials, the staff controls the small motor 8 to turn off, and the spiral conveyor shaft 9 stops conveying the raw materials. Then, the lower pressure plate 601 is driven downward by the cylinder 6 to press the raw materials so that the working box 3 can knead the raw materials. In this way, the raw materials can be automatically added to the working box 3 at a uniform speed and in a uniform amount for kneading operation.
[0026] Embodiment 2: Based on embodiment 1, Figure 4 and Figure 5As shown, it also includes a closing component for closing the connection between the sealing box 5 and the loading frame 7, the closing component includes a sliding baffle 10, a connecting rod 11, a contact plate 12 and a reset spring 13, the sliding baffle 10 is slidingly connected to the front of the sealing box 5, and the upper side of the sliding baffle 10 is fixedly connected to the left and right symmetrical connecting rods 11, the upper ends of the connecting rods 11 extend out of the sealing box 5, and a contact plate 12 is fixedly connected between the upper ends of the left and right connecting rods 11, the lower part of the contact plate 12 is a semi-arc structure, which extends into the sealing box 5 and fits with the cylinder 6 while being squeezed and matched with the lower pressure plate 601, and two reset springs 13 are connected between the upper part of the contact plate 12 and the sealing box 5.
[0027] By setting a closing component, the connection between the sealing box 5 and the loading frame 7 can be closed during mixing to prevent the raw materials from leaking out. The specific operation is as follows: in the initial state, the lower pressing plate 601 is in a downward pressing state, and the sliding baffle 10 is also blocked at the connection between the sealing box 5 and the loading frame 7. When the lower pressing plate 601 is lifted upward to contact with the contact plate 12, the lower pressing plate 601 continues to move upward to push the contact plate 12 to move upward, and the reset spring 13 is deformed. The contact plate 12 moves upward to drive the connecting rod 11 to move upward, and the connecting rod 11 moves upward to drive the sliding baffle 10 to slide upward. Open, at this time, the spiral conveyor shaft 9 can add the raw materials into the sealing box 5 and the working box 3. After a certain amount of raw materials are added, the lower pressure plate 601 moves downward and no longer squeezes the contact plate 12. At this time, under the action of the reset spring 13, the contact plate 12 moves downward and resets. The contact plate 12 moves downward and drives the connecting rod 11 to move downward. The connecting rod 11 moves downward and drives the sliding baffle 10 to slide downward to block the connection between the sealing box 5 and the loading frame 7 again, so as to prevent the raw materials from leaking out from the connection between the sealing box 5 and the loading frame 7 when the lower pressure plate 601 presses down the raw materials.
[0028] like Figure 1 , Figure 6 and Figure 7 As shown, it also includes a cooling component for cooling the lower pressure plate 601, and the cooling component includes a water tank 14, a water pump 15, a water outlet pipe 16, a water inlet pipe 17 and a straight pipe group 18. The water tank 14 is fixedly connected to the front side of the sealing box 5, and the water pump 15 is fixedly connected to the upper right part of the water tank 14. The water pump 15 is connected to the water outlet pipe 16, and the upper left part of the water tank 14 is connected to the water inlet pipe 17. The straight pipe group 18 is fixedly connected inside the lower pressure plate 601, and the tail ends of the water outlet pipe 16 and the water inlet pipe 17 are respectively connected to the two ends of the straight pipe group 18. The water outlet pipe 16 and the water inlet pipe 17 are both telescopic pipes so that they can follow the lifting and lowering movement of the lower pressure plate 601.
[0029] By setting a cooling component, the lower pressure plate 601 can be kept at a certain temperature to avoid excessive temperature affecting the banburying effect. The specific operation is as follows: the water pump 15 is operated to suck the water in the water tank 14 into the water outlet pipe 16, and the water outlet pipe 16 guides the water into the straight pipe group 18. The water in the straight pipe group 18 flows and then passes through the water inlet pipe 17 to be guided back to the water tank 14. The water pump 15 is always in operation to make the water circulate in the straight pipe group 18. The flowing water takes away the heat on the lower pressure plate 601, and then cools the lower pressure plate 601, so that the lower pressure plate 601 maintains a certain temperature to avoid excessive temperature affecting the banburying effect.
[0030] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation shall fall within the protection scope of the present invention.
