Description

Technical Field

[0001] This utility model relates to the field of mold replacement, and more specifically, to a quick-change device for tofu forming molds. Background Technology

[0002] In the tofu production process, changing the tofu molding mold is a crucial step. With the diversification of market demand, tofu producers need to frequently change molding molds of different specifications to produce tofu products of various shapes and sizes. However, existing tofu molding mold changing technologies have many shortcomings, seriously affecting production efficiency and the economic benefits of enterprises.

[0003] Traditional methods of changing tofu forming molds are mostly manual, requiring workers to spend a significant amount of time and effort disassembling and installing the molds. During the replacement process, the molds need precise positioning and adjustment to ensure accurate alignment with other components of the production line. This process is not only cumbersome but also prone to inaccurate positioning, leading to improper mold installation and affecting the quality of the tofu. Furthermore, manual mold replacement necessitates production line shutdowns, causing production interruptions and significantly reducing overall production efficiency.

[0004] Some existing mold changing devices have inadequate structures, lacking stable installation and effective support. During mold changing, the device is prone to shaking and displacement, leading to inaccurate mold changing and potentially damaging the mold and other production equipment. Furthermore, due to structural instability, the device is susceptible to component wear and loosening during long-term use, increasing maintenance costs and failure rates.

[0005] Operating some mold changing devices requires highly skilled and experienced workers, and the process is complex and prone to human error. Furthermore, these devices have complex structures and numerous parts, requiring significant time and effort for inspection, lubrication, and repair during routine maintenance. Moreover, the high frequency of parts replacement leads to a substantial increase in maintenance costs for the company.

[0006] Existing mold changing technologies typically only accommodate a limited number of mold specifications, making it difficult to meet the diverse production needs of enterprises. When enterprises need to produce new specifications of tofu products, they often need to carry out large-scale modifications to the entire production line or replace the mold changing device. This not only increases the enterprise's production costs but also reduces its responsiveness to market changes. Therefore, we have made an improvement by proposing a rapid mold changing device for tofu forming. Utility Model Content

It should be noted that, in the absence of conflict, the embodiments and features and technical solutions in the embodiments of this utility model can be combined with each other. It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0035] Example 1: A quick-change device for tofu forming mold, including a device mounting base 1, a gear bearing 2 on the device mounting base 1, a fixing plate 3 connected to one side of the gear bearing 2, and the fixing plate 3 connected to the device mounting base 1 at the bottom. A spur gear 4 is nested at the bottom shaft of the gear bearing 2. The spur gear 4 is located at the center end of the device mounting base 1. A base mounting fixing plate 5 is embedded on both sides of the device mounting base 1. The base mounting fixing plate 5 is provided with a base mounting keyhole 6.

[0036] A mold changing rotating shaft 7 is embedded in the circular groove of the gear bearing 2. The top of the mold changing rotating shaft 7 is connected to the mold changing rotating disk connecting seat 8, and a mold changing rotating disk connecting pin 9 is embedded above the mold changing rotating disk connecting seat 8.

[0037] A spur gear 10 is meshed with the outer surface of the spur gear 4. A mold changing power hydraulic cylinder 11 is fixedly installed on the upper side of the device mounting base 1. A mold changing telescopic rod 12 is embedded inside the mold changing power hydraulic cylinder 11, and the top of the mold changing telescopic rod 12 is connected to the spur gear 10. An auxiliary rotating wheel mounting plate 13 is provided on the upper part of the device mounting base 1. A circular hole is provided at the center end of the auxiliary rotating wheel mounting plate 13, and the gear bearing 2 is located in the circular hole.

[0038] A mounting plate top plate 14 is fixed above the side of the auxiliary rotating wheel mounting plate 13. A mounting plate top rod 15 is provided below the mounting plate top plate 14, and the mounting plate top rod 15 is connected to the device mounting base 1 through a fixing block. Auxiliary rotating wheel mounting brackets 16 are respectively installed at the four corners of the auxiliary rotating wheel mounting plate 13, and each auxiliary rotating wheel mounting bracket 16 contains a mold changing rotating disk auxiliary rotating wheel 17.

[0039] A tofu forming mold changing rotating plate 18 is installed above the mold changing rotating plate connecting seat 8, and a first tofu forming mold 19 and a second tofu forming mold 21 are placed on the tofu forming mold changing rotating plate 18. A first mold mounting hole 20 is provided below the first tofu forming mold 19, and a second mold mounting hole 22 is connected to the bottom of the second tofu forming mold 21.

[0040] The working principle of the tofu forming mold quick change device is as follows: The device is installed through the device mounting base 1. The base mounting keyhole 6 on the base mounting plate 5 can be used to fix the device in the corresponding working position, ensuring the stability of the device during operation. The mold changing power hydraulic cylinder 11 provides power for mold changing. When the mold changing power hydraulic cylinder 11 is working, the mold changing telescopic rod 12 inside it will extend and retract.

[0041] The top of the mold changing telescopic rod 12 is connected to the spur gear 10. The extension and retraction of the telescopic rod drives the spur gear 10 to move linearly. Since the spur gear 10 is meshed with the outer surface of the circular gear 4, the linear motion of the spur gear 10 is converted into the rotation of the circular gear 4. The bottom shaft of the circular gear 4 is nested in the bottom shaft of the gear bearing 2. When the circular gear 4 rotates, it drives the gear bearing 2 to rotate. The mold changing rotating shaft 7 is embedded in the circular groove on the gear bearing 2. The rotation of the gear bearing 2 drives the mold changing rotating shaft 7 to rotate.

[0042] The top of the mold changing rotating shaft 7 is connected to the mold changing rotating disk connecting seat 8, which in turn causes the mold changing rotating disk connecting seat 8 to rotate. The mold changing rotating disk connecting seat 8 is connected to the tofu forming mold changing rotating disk 18 through the mold changing rotating disk connecting pin 9, ultimately driving the tofu forming mold changing rotating disk 18 to rotate. The auxiliary rotating wheel mounting plate 13 is set above the device mounting base 1, and its central circular hole is used to accommodate the gear bearing 2. Auxiliary rotating wheel mounting brackets 16 are respectively installed at the four corners of the auxiliary rotating wheel mounting plate 13, and each auxiliary rotating wheel mounting bracket 16 contains a mold changing rotating disk auxiliary rotating wheel 17. These auxiliary rotating wheels 17 are in contact with the tofu forming mold changing rotating disk 18, and play a role in assisting support and reducing friction when the tofu forming mold changing rotating disk 18 rotates, ensuring smooth rotation.

[0043] The tofu forming mold replacement rotating plate 18 holds a first tofu forming mold 19 and a second tofu forming mold 21, which are respectively connected to the rotating plate through the first mold mounting hole 20 and the second mold mounting hole 22.

[0044] By controlling the extension and retraction of the hydraulic cylinder 11 for mold changing, the tofu forming mold changing rotating plate 18 is rotated by a corresponding angle, thereby realizing the rapid replacement of the first tofu forming mold 19 and the second tofu forming mold 21 to meet different production needs.

[0045] Example 2: A quick-change device for tofu forming molds. The application scenario of this device is in the tofu forming workshop of a tofu production company. To improve production efficiency, it is necessary to quickly switch between different specifications of tofu forming molds on the same production line. The company adopted the aforementioned quick-change device for tofu forming molds. The specific implementation process of this device in actual production is described in detail below.

[0046] Implementation steps: First, determine the installation position of the device mounting base 1 according to the layout and installation requirements of the production line. Using the mounting keyholes 6 on the base mounting plate 5, securely fix the device mounting base 1 to the designated position on the production line with bolts, ensuring that the entire device will not shake or shift during operation. Install the auxiliary rotary wheel mounting plate 13, placing it above the device mounting base 1, so that the gear bearing 2 is located in the circular hole at the center end of the auxiliary rotary wheel mounting plate 13. Then, connect the mounting plate top plate 14 to the device mounting base 1 using the mounting plate top rod 15 and the fixing block, further reinforcing the auxiliary rotary wheel mounting plate 13.

[0047] Place the first tofu forming mold 19 and the second tofu forming mold 21 on the tofu forming mold changing rotating plate 18, so that the first mold mounting hole 20 under the first tofu forming mold 19 and the second mold mounting hole 22 under the second tofu forming mold 21 accurately match the corresponding positioning structure on the tofu forming mold changing rotating plate 18, so as to ensure that the molds are installed firmly and in precise positions.

[0048] The mold changing rotating shaft 7 is embedded in the circular groove of the gear bearing 2, and the tofu forming mold changing rotating disk 18 is connected to the mold changing rotating shaft 7 through the mold changing rotating disk connecting seat 8 and the mold changing rotating disk connecting pin 9, so as to ensure smooth transmission between rotating parts.

[0049] Install the mold replacement hydraulic cylinder 11 and fix it to the upper side of the device mounting base 1. Connect the hydraulic lines of the mold replacement hydraulic cylinder 11 to ensure that the hydraulic system can normally provide power to the mold replacement hydraulic cylinder 11.

[0050] The mold replacement telescopic rod 12 is embedded inside the mold replacement power hydraulic cylinder 11, and its top end is connected to the spur gear 10 to ensure that the telescopic rod's extension and retraction movement can be accurately transmitted to the spur gear 10.

[0051] Mold changeover during production:

[0052] Initial state: Assume that the production line initially uses the first tofu forming mold 19 for tofu forming production. At this time, the tofu forming mold changing turntable 18 is in the corresponding position, so that the first tofu forming mold 19 is in the working position.

[0053] Replacement command trigger: When the production task requires replacement with the second tofu forming mold 21, the operator issues a mold replacement command through the control system.

[0054] Power drive: After receiving the instruction, the hydraulic cylinder 11 for mold changing starts to work, and the hydraulic oil pushes the mold changing telescopic rod 12 to extend.

[0055] Transmission conversion: The extension and retraction of the mold changing telescopic rod 12 drives the spur gear 10 to perform linear motion. Since the spur gear 10 is meshed with the outer surface gear of the circular gear 4, the linear motion of the spur gear 10 is converted into the rotation of the circular gear 4.

[0056] Rotating component linkage: The rotation of the spur gear 4 drives the gear bearing 2 to rotate, which in turn causes the tofu forming mold changing rotating disk 18 to rotate through the mold changing rotating shaft 7, the mold changing rotating disk connecting seat 8, and the mold changing rotating disk connecting pin 9.

[0057] Auxiliary support: During the rotation of the tofu forming mold changing rotating plate 18, the auxiliary rotating plates 17 at the four corners of the auxiliary rotating plate 13 contact the tofu forming mold changing rotating plate 18, which plays a role in providing auxiliary support and reducing friction, thus ensuring smooth rotation.

[0058] Mold positioning: After the tofu forming mold replacement turntable 18 rotates to the appropriate angle, the second tofu forming mold 21 arrives at the working position, and the mold replacement is completed. At this time, the production line can immediately use the second tofu forming mold 21 to produce tofu.

[0059] During production, all components of the device are regularly inspected, including gear bearings 2, spur gears 4, straight gears 10, the mold changing hydraulic cylinder 11, and the mold changing telescopic rod 12, to ensure they are well lubricated, securely connected, and free from wear or damage. The rotation of the mold changing rotary table auxiliary wheel 17 is checked, and any abnormalities are promptly adjusted or replaced. The hydraulic system is regularly maintained, with checks on the hydraulic oil level, quality, and pressure to ensure it provides stable and reliable power for mold changing. Through these specific implementation processes, this tofu forming mold quick-change device enables rapid and accurate mold replacement on the tofu production line, significantly improving production efficiency and meeting the diverse production needs of enterprises.

[0060] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above.
