Description

Technical Field

[0001] This utility model relates to the field of kneading machine technology, specifically to a reducer support for a tea kneading machine. Background Technology

[0002] A tea rolling machine is a machine that preserves the fiber structure of tea leaves, ensures uniform tea quality, and is easy to operate. This particular tea rolling machine utilizes a new energy-saving reducer manufactured using the utility model patent technology (CN202323172404.2, owned by Huangshan Baiyun Machinery Co., Ltd.) for an energy-saving helical gear electric mechanism. However, on the 6CR-55 rolling machine, due to space limitations between the reducer's connecting seat and the housing, the old-style worm gear reducer and rolling disc connection method (such as...) cannot be used. Figure 8 and Figure 9 The upper connecting seat is connected to the kneading disc flange of the tea kneading machine by four bolts. This connection method is not suitable for the new energy-saving reducer used in tea kneading machines manufactured with energy-saving helical gear electric mechanisms. Furthermore, according to this patent... Figure 5 and Figure 6 It is known that the original old-style worm gear reducer base was composed of a base and a middle seat (both of which were castings). However, due to the high price and bulky structure of castings, and the susceptibility to defects in castings leading to scrap, the new energy-saving reducer, with its new transmission design, has significantly improved transmission efficiency and a noticeably smaller external structure. If a structure similar to the original old-style worm gear reducer base (such as...) is still used... Figure 9 Because the reducer structure is smaller, the reducer base must be designed to be taller and heavier than the old-fashioned worm gear reducer base, resulting in higher costs.

[0003] In summary, there is a need for a speed reducer support for a tea rolling machine. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a speed reducer support for a tea kneading machine, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A reducer support base for a tea rolling machine includes an energy-saving reducer. The lower end of the reducer's gearbox is fixedly connected to a lower gearbox connecting seat. The lower gearbox connecting seat is connected to an upper connecting flange via a first middle seat bolt. The upper connecting flange is located on the outer side of the middle seat near the top. The lower connecting flange is fixedly connected to the outer side of the middle seat near the bottom. The upper gearbox connecting seat is fixedly connected to the upper end of the reducer's gearbox. The upper gearbox connecting seat is connected to a rolling disc connecting seat via connecting bolts. The rolling disc connecting seat is fixedly located on the outer side of the rolling disc body. Three connecting bolt holes are respectively provided on the rolling disc connecting seat and the upper gearbox connecting seat. The connecting bolt holes are as follows: Figure 4 The bolt holes are unevenly distributed in a triangular shape. The bolt holes are drilled holes on the kneading disc connecting seat and tapped holes on the gearbox upper connecting seat. The bolt fasteners pass through from top to bottom to fix the kneading disc connecting seat and the gearbox upper connecting seat in place.

[0007] Furthermore, the lower connecting flange of the middle seat is connected to the lower connecting flange by a second middle seat bolt fastener, and the lower connecting flange is fixedly installed on the outer side of the lower seat of the gearbox near the top.

[0008] Furthermore, the bottom of the gearbox base is welded to a base angle steel, and the base angle steel has anchor bolt holes.

[0009] Furthermore, a motor support is welded to the right side of the gearbox seat, and the motor support and the motor contact support of the energy-saving gearbox are connected.

[0010] This utility model provides a speed reducer support for a tea rolling machine. Compared with the prior art, it has the following advantages:

[0011] This patent, through strength calculations of the connecting bolts and fasteners, changed the size of the connecting bolts and fasteners, and changed the number of connecting bolts to a three-bolt connection. It also changed the tapping on the kneading disc connecting seat and the drilling on the gearbox connecting seat to drilling on the kneading disc connecting seat and tapping on the gearbox connecting seat. This overcomes the problem of the energy-saving gearbox being able to connect with existing kneading machines without changing the gearbox design. This not only reduces the design costs incurred by changing the gearbox design, but also ensures the versatility of the gearbox in other applications. Furthermore, the entire gearbox base and the lower base angle steel are all welded from steel plates, avoiding scrap caused by casting defects. Since steel plates have better toughness than castings, they can effectively absorb the impact force transmitted from the machine, and the overall structural weight is reduced by more than 20%. The price of steel is also about 30% lower than cast iron. This welded gearbox base structure not only has high strength and good vibration absorption, but also significantly reduces material costs by about 45%. Attached Figure Description

[0024] Example 1

[0025] To address the technical problems in the background section, the following gearbox support for a tea rolling machine is provided:

[0026] Combination Figures 1-9 As shown, this utility model provides a reducer support base for a tea kneading machine, including an energy-saving reducer 1. The lower end of the reducer of the energy-saving reducer 1 is fixedly connected to a lower reducer connecting seat 2. The lower reducer connecting seat 2 is connected to an upper connecting flange 3 via a first middle seat bolt fastener 9. The upper connecting flange 3 is located on the outer side of the middle seat 4 of the reducer, near the top. A lower connecting flange 5 is fixedly connected to the outer side of the middle seat 4, near the bottom. The upper reducer connecting seat 12 is fixedly connected to the upper reducer of the reducer of the energy-saving reducer 1. The upper reducer connecting seat 12 is connected to a kneading disc connecting seat 14 via connecting bolt fasteners 13. The kneading disc connecting seat 14 is fixedly located on the outer side of the kneading disc body 15. Three connecting bolt holes are respectively opened on the kneading disc connecting seat 14 and the upper reducer connecting seat 12. The connecting bolt holes are as follows... Figure 4 The connecting bolt holes are unevenly distributed in a triangular shape. The connecting bolt holes are drilled on the kneading disc connecting seat 14 and tapped on the gearbox upper connecting seat 12. The connecting bolt fastener 13 passes through from top to bottom to fix the kneading disc connecting seat 14 and the gearbox upper connecting seat 12.

[0027] In this embodiment, the lower connecting flange 5 of the middle seat is connected to the lower connecting flange 6 by the second middle seat bolt fastener 11. The lower connecting flange 6 is fixedly installed on the outside of the lower seat 8 of the gearbox near the top. The bottom of the lower seat 8 of the gearbox is welded to the bottom of the lower seat angle steel 7, and the lower seat angle steel 7 is provided with anchor bolt holes. The right side of the middle seat 4 of the gearbox is welded to the motor support 10, and the motor support 10 and the motor contact support of the energy-saving reducer 1 are connected.

[0028] The anchor bolt holes on the lower angle steel 7 facilitate the installation of anchor bolts on the machine. The original old-style worm gear reducer was connected to the kneading disc via bolts through an upper connecting seat. Figure 6 If the kneading disc of an energy-saving kneading machine also uses a bolt-screw-in connection from bottom to top, then... Figure 9It can be seen that for a secure and effective connection, the bolt length (excluding the bolt head) should be approximately 45mm. However, the gap between the upper connecting seat (in this patent, the upper connecting seat of the gearbox) and the energy-saving gearbox housing (in this patent, the gearbox of the energy-saving gearbox) is only 17mm. Therefore, the total length of the connecting bolt (in this patent, the connecting bolt fastener) including the bolt head must also be less than 17mm. But the upper connecting seat is 19mm thick, making this method unsuitable. If a connection method using bolts screwed in from top to bottom is adopted (e.g....),... Figure 7 Two of the four bolt holes can only be drilled from bottom to top due to the structure between the kneading disc body 15 and the kneading disc connecting seat 14. As a result, the upper part becomes a blind hole for the bolts, and the bolts cannot be screwed in from top to bottom. To address this, we changed the size of the connecting bolt fasteners by calculating the strength of the fasteners and changed the number of connecting bolt fasteners from 4 to 3 bolts. We also changed the tapping on the kneading disc connecting seat 14 and drilling on the gearbox connecting seat 12 to drilling on the kneading disc connecting seat 14 and tapping on the gearbox connecting seat 12. This overcomes the problem that the gearbox of the energy-saving reducer 1 can be connected to the existing kneading machine without changing the gearbox design. This not only reduces the design cost of the gearbox of the energy-saving reducer 1 due to the change of the gearbox design, but also ensures the universality of the gearbox when the energy-saving reducer 1 is used in other situations.

[0029] Working principle and usage process of this utility model:

[0030] In use:

[0031] The lower end of the gearbox of the energy-saving reducer 1 is fixedly connected to the gearbox middle seat 4 through the gearbox lower connecting seat 2, the first middle seat bolt fastener 9 and the middle seat upper connecting flange 3. The gearbox middle seat 4 is fixedly connected to the gearbox lower seat 8 through the middle seat lower connecting flange 5, the second middle seat bolt fastener 11 and the lower seat connecting flange 6, thereby completely connecting the entire gearbox seat into a whole. The upper end of the gearbox of the energy-saving reducer 1 is connected to the kneading disc body 15 through the gearbox upper connecting seat 12, the connecting bolt fastener 13 and the kneading disc connecting seat 14. The output shaft of the energy-saving reducer 1 passes through the gearbox upper connecting seat 12 and the kneading disc connecting seat 14 and is connected to the external curved arm. The curved arm is drawn in this patent but not marked. The curved arm is used to drive the kneading drum on the drum frame to rotate on the kneading disc body 15.
