Abstract
Description
Technical Field
[0001] This utility model relates to the field of foaming machine technology, and in particular to a foaming machine for producing foam boxes. Background Technology
[0002] A foaming machine, also known as a foam generator, is a device that produces foam by mixing a foaming agent with an aqueous solution of a certain concentration. The foaming agent itself cannot automatically become foam; it needs to be stirred inside the foaming machine to become foam. It is a device specifically designed to generate foam.
[0003] For example, Chinese utility model patent application number CN202323036784.7 discloses a foaming machine for producing foam boxes, including a tank. Support legs are fixedly mounted in a ring on the lower surface of the tank. A feed hopper is fixedly mounted on the upper surface of the tank near one end. A discharge pipe is fixedly mounted on the other end of the tank. A stirring structure is provided inside the tank, comprising a servo motor, a first bearing, a rotating shaft, gears, an annular ring, a toothed groove, a rotating rod, a second bearing, a connecting seat, a first stirring rod, and a second stirring rod. This utility model's foaming machine for producing foam boxes allows the first and second stirring rods, as well as the rotating rod, to rotate around the rotating shaft, stirring the raw materials in the tank. Simultaneously, the first and second stirring rods can rotate around the rotating rod, resulting in more thorough stirring of the raw materials in the tank, avoiding uneven stirring and improving stirring efficiency.
[0004] Although the aforementioned foaming machine can stir the raw materials inside the tank, it cannot clean the raw materials adhering to the inner wall of the tank. If the raw materials adhere to the inner wall of the tank for too long and deteriorate, it will affect the quality of the raw materials that are subsequently added to the tank for stirring. Utility Model Content
[0005] This utility model discloses a foaming machine for producing foam boxes, which solves the problem that the raw materials adhering to the inner wall of the tank cannot be cleaned, and that the raw materials adhering to the inner wall of the tank for too long will affect the quality of the subsequent raw materials after mixing.
[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0007] A foaming machine for producing foam boxes includes a tank body with a cover plate fixed to it. An annular ring located inside the tank body is fixed to the bottom of the cover plate. Gear grooves are formed on the inner wall of the annular ring. A vertical tube, rotatably connected to and located inside the annular ring, passes through the top of the cover plate. A motor for driving the vertical tube is mounted on the cover plate. A circular shell located below the annular ring is fixed to the bottom of the vertical tube. Two rotatably connected stirring rods pass through the circular shell, symmetrically distributed left and right. A connecting gear is fixed to the top of each stirring rod, with teeth on the connecting gear meshing with the gear grooves. A vertical shell in contact with the inner wall of the tank body is connected to the bottom of the circular shell, and a nozzle is connected to the vertical shell. A water inlet pipe is rotatably connected to the top of the vertical tube. A discharge pipe and a feed pipe are connected to the tank body.
[0008] Compared with the prior art, the present invention has the following beneficial effects:
[0009] After the raw materials are added to the tank, the motor is started to drive the vertical tube to rotate. The vertical tube, through the circular shell, drives two stirring rods to rotate around the axis at the bottom of the tank. This causes the stirring rods to agitate the raw materials inside the tank. The vertical shell, in contact with the inner wall of the tank, scrapes off any raw materials adhering to the inner wall, allowing these materials to be added to the agitation process. As the stirring rods rotate with the circular shell, the connecting gears also rotate. Because the teeth on the connecting gears mesh with the grooves in the annular ring, the rotation of the connecting gears along with the stirring rods causes the stirring rods to rotate, allowing them to rotate around their own axis at the bottom for better agitation. The raw materials inside the tank are stirred. After the raw materials are stirred and discharged from the discharge pipe on the tank, the water inlet pipe can be connected to an external water source, allowing water to enter the vertical pipe through the water inlet pipe. The water in the vertical pipe can then enter the vertical shell through the round shell. The water in the vertical shell is sprayed out through the nozzle, which can clean the inside of the tank. Finally, the wastewater is discharged through the discharge pipe. This invention can effectively scrape off the raw materials adhering to the inner wall of the tank and add them to the stirring process. After the raw materials are stirred and discharged from the tank, the inside of the tank can also be effectively cleaned, preventing a large amount of raw materials remaining inside the tank from deteriorating over time and affecting the quality of subsequent raw material stirring.

[0015] The specific content of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.
[0016] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides a foaming machine for producing foam boxes, including a tank body 1, a cover plate 2 fixed on the tank body 1, an annular ring 21 fixed at the bottom of the cover plate 2 inside the tank body 1, a toothed groove 22 on the inner wall of the annular ring 21, a vertical tube 23 rotatably connected to and located inside the annular ring 21 passing through the top of the cover plate 2, and a motor 24 for driving the vertical tube 23 on the cover plate 2; a circular shell 3 fixed at the bottom of the vertical tube 23 below the annular ring 21, two rotatably connected stirring rods 32 passing through the circular shell 3, the two stirring rods 32 being symmetrically distributed left and right, a connecting gear 33 fixed at the top of the stirring rods 32, the teeth on the connecting gear 33 meshing with the toothed groove 22; a vertical shell 4 in contact with the inner wall of the tank body 1 is connected to the bottom of the circular shell 3, a nozzle 41 is connected to the vertical shell 4, and a water inlet pipe 27 is rotatably connected to the top of the vertical tube 23; a discharge pipe 5 and a feed pipe 6 are connected to the tank body 1.
[0017] like Figure 1 , Figure 2 and Figure 3 As shown, a stirring paddle 8 is fixed at the center of the bottom of the cylindrical shell 3; two symmetrical circular holes are opened at the top of the cylindrical shell 3, and a short cylinder 31 is fixed inside the circular holes. The bottom end of the stirring rod 32 passes through the inside of the short cylinder 31 and is rotatably connected to the short cylinder 31. The stirring paddle 8, together with the two stirring rods, can perform all-round and thorough stirring of the raw materials in the tank 1, avoiding the presence of stirring dead zones in the tank 1; the short cylinder 31 is designed so that the stirring rod 32 can rotate smoothly around its own bottom center (the stirring rod 32 rotates).
[0018] like Figure 1As shown, a drive gear 25 is fixed on the shaft of the motor 24, and a driven gear 26 that meshes with the drive gear 25 is fixed on the vertical tube 23; the feed pipe 6 is located below the circular shell 3. The teeth of the drive gear 25 mesh with those of the driven gear 26. After the motor 24 is started, the drive gear 25 can drive the driven gear 26 to rotate, causing the vertical tube 23 to rotate; the feed pipe 6 is located below the circular shell 3, which can prevent the raw material from falling onto the top of the circular shell 3.
[0019] like Figure 1 , Figure 2 and Figure 3 As shown, the circular shell 3 has a set of perforations 34, the vertical shell 4 is located inside the set of perforations 34, the cover plate 2 has a hollow top plate 7 above it, the bottom of the top plate 7 is connected to a set of thin tubes 71 that pass through the cover plate 2, the thin tubes 71 are located outside the annular ring 21, the set of thin tubes 71 are respectively corresponding to the set of perforations 34, and the thin tubes 71 have water outlet holes; an electric telescopic rod 72 is fixed on the cover plate 2, and the telescopic end of the electric telescopic rod 72 is connected to the top plate 7. The bottom end of the thin tube 71 is also provided with a water outlet, so that after the raw materials in the tank 1 have been stirred and discharged, the electric telescopic rod 72 can be activated to move the top plate 7 downwards, and the thin tube 71 will move downwards and pass through the perforation 34 on the circular shell 3 (the setting of the perforation 34 will not affect the sealing of the circular shell 3, and a thin cylinder for the thin tube 71 to pass through can also be set in the perforation 34); after the water supply pipe on the top plate 7 is connected to an external water source, water can enter the thin tube 71, and the water in the thin tube 71 will be discharged through the water outlet (the water outlet on the thin tube 71) The hole is opened on the side of the thin tube 71 near the vertical shell 4, so that the raw materials on the vertical shell 4 can be rinsed. The water outlet at the bottom of the thin tube 71 can rinse the part of the vertical shell 4 below the bottom of the thin tube 71 when the thin tube 71 can no longer move downwards. Alternatively, the water outlet can be not opened at the bottom of the thin tube 71, and the length of the thin tube 71 can be set to cover the entire vertical shell 4, so that the surface of the vertical shell 4 can be effectively rinsed. A set of thin tubes 71 surrounds the vertical shell 4, so that the surface of the vertical shell 4 can be rinsed in all directions.
[0020] like Figure 1 As shown, a scraper 42 is fixed to the bottom of the vertical shell 4, which contacts the bottom of the tank 1. When the vertical shell 4 rotates with the circular shell 3, the scraper 42 rotates as well, and can scrape off the raw material adhering to the bottom of the tank 1.
[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the bottom of the circular shell 3 has one set of vertical shells 4, and two sets of nozzles 41 on the vertical shells 4. Grooves are formed on both the side of the vertical shell 4 near the stirring rod 32 and the side away from the stirring rod 32, and the two sets of nozzles 41 are located in the two grooves on the vertical shell 4 respectively. One set of vertical shells 4 consists of four shells, which are distributed in a front-back, left-right, and right-backwards pattern (as shown in the diagram). Figure 1 (as shown in the diagram), and the arrangement of two sets of nozzles 41 on the vertical shell 4, so that when water is sprayed out through the two sets of nozzles 41 on the vertical shell 4, the water can wash the inner wall of the tank 1 and the surface of the stirring rod 32 and the stirring paddle 8, thus preventing raw materials from adhering to the surface of the stirring rod 32 and the stirring paddle 8.
[0022] In use, after the raw materials are put into the tank 1, the motor 24 is started to drive the vertical tube 23 to rotate. The vertical tube 23 then drives the two stirring rods 32 to rotate around the axis at the bottom of the tank 1 through the round shell 3, so that the stirring rods 32 stir the raw materials in the tank 1. The vertical shell 4 contacts the inner wall of the tank 1 (the side of the vertical shell 4 that contacts the inner wall of the tank 1 is arc-shaped to better fit the inner wall of the tank 1), so that the raw materials adhering to the inner wall of the tank 1 can be scraped off, and the raw materials adhering to the inner wall of the tank 1 can also be added to the stirring. And when the stirring rods 32 rotate with the round shell 3, the connecting gear 33 rotates with the stirring rods 32. The teeth on the connecting gear 33 mesh with the tooth groove 22 in the annular ring 21. Therefore, after the connecting gear 33 rotates with the stirring rod 32, it can drive the stirring rod 32 to rotate, so that the stirring rod 32 can rotate around its own bottom axis, so as to better stir the raw materials in the tank 1. After the raw materials are stirred and discharged from the discharge pipe 5 on the tank 1, the water inlet pipe 27 can be connected to an external water source, so that water enters the vertical pipe 23 through the water inlet pipe 27. The water in the vertical pipe 23 can then enter the vertical shell 4 through the round shell 3. The water in the vertical shell 4 can be sprayed out through the nozzle 41 to clean the inside of the tank 1. Finally, the wastewater is discharged through the discharge pipe 5.
