Description

Technical Field

[0001] The utility model belongs to the technical field of granulators, and particularly relates to a novel outer drum connecting mechanism. Background Art

[0002] Granulators are mainly used for the production of raw materials in the chemical industry and other fields, such as plastic granules for injection molding, etc. Granules are used as injection molding raw materials, food additives, etc. The basic working principle of the granulator is as follows: the outer drum is filled with molten material for making the above-mentioned granules, the outer drum is positioned and rotated under the action of the support structure, a plurality of holes for discharging the molten material are provided on the wall of the outer drum, and a steel belt moving in the horizontal direction is provided under the outer drum. The steel belt is used to receive and cool the molten material dripping from the holes in the drum wall. After the molten material on the steel belt cools, solid particles are formed. Finally, the solid particles are removed from the steel belt using tools. The solid particles can be used to fill the gap between the product and the packaging bag when packaging the product.

[0003] Generally, both ends of the outer rotating drum are supported by a supporting structure, and the outer rotating drum is rotated by a chain-sprocket transmission assembly on the supporting structure. In the structure where the sprocket and the outer rotating drum are connected in transmission, the driving drum on which the sprocket is mounted needs to be connected to the outer rotating drum so that the outer rotating drum and the driving drum are fixed together. The existing method mainly involves setting screw holes at both ends of the outer rotating drum, and fixing the outer rotating drum and the driving drum together by cooperating with the screw holes. However, it is difficult to align the pin holes (pin hole diameter 7mm) during the installation process, and it is easy to wear and break during the rotation process later. Therefore, a new outer rotating drum connection mechanism is needed. Utility Model Content

Both ends of the outer rotating cylinder are integrally provided with joints, one side of each of the two joints is provided with a hexagonal connection hole, and one end of the driving cylinder is integrally provided with a hexagonal joint that cooperates with the hexagonal connection hole.

[0007] As a further optimization solution of the present invention, a connecting plate is integrally provided on the outer side of one end of the driving cylinder close to the hexagonal joint, and a connecting sleeve that cooperates with the connecting plate is sleeved on the outer side of the driving cylinder.

[0008] As a further optimization solution of the present invention, a positioning groove is provided between one end of the connecting sleeve and the connecting plate, and a sprocket is provided in the positioning groove.

[0009] As a further optimization solution of the present invention, a sealing groove located inside the hexagonal connection hole is provided at one end of the joint, and a sealing ring cooperating with the sealing groove is provided at one end of the driving cylinder close to the hexagonal joint.

[0023] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0024] Example 1

[0025] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 As shown, a new type of outer drum connection mechanism includes an outer drum 1 and a driving drum 2. The arc surface of the outer drum 1 is provided with a plurality of through holes 10, through which the molten material inside the outer drum 1 can flow out. Both ends of the outer drum 1 are integrally provided with joints 7, and one side of the two joints 7 is provided with a hexagonal connection hole 8. One end of the driving drum 2 is integrally provided with a hexagonal joint 5 that cooperates with the hexagonal connection hole 8. By plugging and unplugging the hexagonal joint 5 at one end of the driving drum 2 and the hexagonal connection hole 8 at one end of the outer drum 1, the driving drum 2 can be quickly connected to one end of the outer drum 1, so that the driving drum 2 can rotate. When driving the outer drum 1 to rotate, the driving drum 2 and the outer drum 1 are fitted together by means of an inner hexagonal socket, which improves the installation efficiency and prevents the screw from wearing and loosening between the screw and the screw hole, thereby improving the stability of the connection between the two. A sealing groove 9 is provided at one end of the joint 7 and is located inside the hexagonal hole 8. A sealing ring 6 is provided at one end of the driving drum 2 close to the hexagonal joint 5 and cooperates with the sealing groove 9. The sealing ring 6 is inserted into the sealing groove 9 to improve the sealing of the connection part and prevent material leakage. A plurality of screw holes 13 are provided at one end of the joint 7, and one side of the driving drum 2 is connected to the screw hole 13 through a screw.

[0026] Figure 7 、 Figure 8 As shown, an annular groove 12 and a screw hole 13 are provided at one end of the existing outer rotating cylinder 1, and a ring that fits with the annular groove 12 is provided at one end of the driving cylinder 2. By inserting the ring at one end of the driving cylinder 2 into the annular groove 12 at one end of the outer rotating cylinder 1, and then matching the screw with the screw hole 13, the driving cylinder 2 and the outer rotating cylinder 1 are fixed together, and the outer rotating cylinder 1 can also be driven to rotate by rotating the driving cylinder 2.

[0027] like Figure 4、 Figure 6 、 Figure 9 As shown, a connecting plate 4 is integrally provided on the outer side of the end of the drive cylinder 2 near the hexagonal joint 5. A connecting sleeve 3 is sleeved on the outer side of the drive cylinder 2 to cooperate with the connecting plate 4. A positioning groove 11 is provided between one end of the connecting sleeve 3 and the connecting plate 4. A sprocket 14 is provided in the positioning groove 11. A chain is provided on the sprocket 14, and the other end of the chain is driven by a motor. During use, the motor first drives the chain to rotate, and the chain drives the sprocket to rotate, which in turn drives the drive cylinder 2 to rotate. Then, the outer drum 1 is driven to rotate through the connecting structure to complete the granulation.

[0028] It should be noted that, when installing, this new type of outer drum connection mechanism first completes the transmission connection between the driving drum 2 and the outer drum 1 by inserting and matching the hexagonal joint 5 at one end of the driving drum 2 with the hexagonal connection hole 8 at one end of the outer drum 1. This not only allows the driving drum 2 to be quickly installed at one end of the outer drum 1, but also allows the outer drum 1 to rotate by rotating the driving drum 2, thereby improving the stability of the connection.

[0029] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
