Abstract
Description
Technical Field
[0001] The utility model is applied to the technical field of bunker cover pressing, and particularly relates to a high-pressure bunker cover pressing device for HPP equipment. Background Art
[0002] In the field of pre-packaged product production, with the continuous development of automated equipment and the increasing demand for food safety, more and more manufacturers are replacing traditional manual production and packaging with automated equipment. For example, pre-packaged beverages require airtightness testing and sterilization after product packaging. Before testing or ultra-high pressure sterilization, several products need to be placed in a high-pressure chamber. The high-pressure chamber is then transported to a sealing and pressurizing station. A downward pressure mechanism drives the high-pressure chamber cover down to pressurize the chamber, and then high-pressure fluid is introduced to pressurize the products inside the chamber. Currently, the downward pressure mechanism on the market mainly uses a downward pressure cylinder to drive the chamber cover downward, without secondary protection measures. This downward pressure mechanism is simple in structure, and the downward pressure device will experience a certain amount of downward pressure stroke error during long-term use. During the process of pressurization to ultra-high pressure, it is easy for the chamber cover to pop out due to loose pressure, resulting in losses. Alternatively, the pressed chamber cover can be manually re-locked to the chamber body using a locking mechanism. This method has high labor costs and requires external traction equipment to complete the locking operation, which is inefficient and does not meet the requirements of high-efficiency production. If a high-pressure bunker cover pressing device for HPP equipment can be designed that has a simple structure, precise positioning, can cooperate with the conveying mechanism to seal and pressurize the bunker body, and can provide pressurization protection through a synchronous side push mechanism, the above problems can be solved.

[0021] like Figures 1 to 8As shown, in this embodiment, the utility model includes a support frame 1, a downward pressure component 2 and a high-pressure chamber cover 3, a through groove 4 is provided in the middle of the support frame 1, the downward pressure component 2 includes a U-shaped bracket 5, a plurality of downward pressure cylinders 6 and a pressure plate 7, the U-shaped bracket 5 is connected to the upper end of the through groove 4, the upper end surface of the pressure plate 7 is movably connected to the U-shaped bracket 5 through a plurality of linear bearings 9, a plurality of the downward pressure cylinders 6 are respectively arranged on both sides of the U-shaped bracket 5, the upper ends of the linear bearings 9 on both sides of the U-shaped bracket 5 are respectively connected through connecting plates 10, the movable ends of the downward pressure cylinders 6 are connected to the connecting plates 10, the high-pressure chamber cover 3 is connected to the lower end surface of the pressure plate 7, and a plurality of the downward pressure cylinders 6 drive the high-pressure chamber cover 3 to cooperate with the sealing end of the external chamber body passing through the middle of the through groove 4. It can be seen that the initial state is that the pressing assembly 2 is in a high position. When the external warehouse body enters the through slot 4, several of the pressing cylinders 6 drive the pressure plate 7 to descend, so that the high-pressure warehouse cover 3 is connected to the sealing end of the external warehouse body to achieve sealing. The U-shaped bracket 5 can reduce the overall size and weight of the pressing assembly 2 while ensuring force balance. Multiple groups of pressing cylinders 6 can ensure that the pressing force is more uniform and the pressing sealing is better.
[0022] like Figure 1 、 Figure 3 as well as Figure 8 As shown, in this embodiment, an oil pipeline passage 11 is provided in the middle of the upper end of the U-shaped bracket 5. An oil pipeline module 12 is also provided on the upper end surface of the U-shaped bracket 5. An oil outlet pipe through-hole 13 is provided in the middle of the pressure plate 7. An oil outlet pipe 14 in the middle of the oil pipeline module 12 is connected to the high-pressure chamber cover 3 through the oil pipeline passage 11 and the oil outlet pipe through-hole 13. Thus, the oil outlet pipe 14 in the middle of the oil pipeline module 12 passes through the U-shaped bracket 5 and is connected to the high-pressure chamber cover 3, which effectively saves equipment volume and provides protection for the oil outlet pipe 14.
[0023] like Figures 1 to 7As shown, in this embodiment, a side push limit assembly 15 is provided on one side of the U-shaped bracket 5, and the side push limit assembly 15 includes a side push connecting plate 151, a side push block 152 and a plurality of side push cylinders 153. The side push connecting plate 151 is connected to one side of the lower end surface of the U-shaped bracket 5, and slide rails 154 are provided on both sides of the side push block 152. Sliding grooves 155 are provided on both sides of the lower end surface of the side push connecting plate 151. The side push block 152 slides with the sliding grooves 155 through the slide rails 154. A plurality of side push cylinders 153 are provided at both ends of the lower end surface of the U-shaped bracket 5, and the movable ends of the plurality of side push cylinders 153 cooperate with the side push block 152. It can be seen that when the high-pressure chamber cover 3 is not pressed down to seal, the side of the side push block 152 blocks the side of the pressure plate 7. After the high-pressure chamber cover 3 is pressed down, the lowest point of the side push block 152 is slightly higher than the highest point of the pressure plate 7. Several side push cylinders 153 drive the side push block 152 to move to the upper end of the pressure plate 7 to achieve limiting, preventing the high-pressure chamber cover 3 from bouncing up and falling off in an ultra-high pressure environment. Several slide rails 154 and several sliding grooves 155 can make the sliding of the side push block 152 more stable.
[0024] like Figure 1 、 Figure 2 as well as Figure 5 As shown, in this embodiment, a cylinder connecting block 156 is provided on the outside of the side thrust block 152, and the movable ends of the side thrust cylinders 153 at both ends of the lower end surface of the U-shaped bracket 5 are connected to both ends of the cylinder connecting block 156. A plurality of the side thrust cylinders 153 drive the side thrust block 152 to cooperate with the pressure plate 7. Thus, it can be seen that the movable ends of the two groups of side thrust cylinders 153 are respectively connected to both ends of the cylinder connecting block 156, so that the force during the side thrust process is more uniform, and the displacement of the side thrust block 152 due to uneven force is prevented.
[0025] like Figure 5 and Figure 6 As shown, in this embodiment, the side thrust block 152 is provided with an escape groove 157 on the side close to the oil outlet pipe 14, and the escape groove 157 cooperates with the oil outlet pipe 14. Thus, the escape groove 157 can prevent the side thrust block 152 from colliding with the oil outlet pipe 14 and can move the side thrust block 152 to the middle of the upper end of the pressure plate 7, thereby increasing the limiting area.
[0026] like Figure 1 and Figure 8 As shown, in this embodiment, an oil inlet pipe 16 is provided at one end of the oil delivery pipe module 12, and the oil inlet pipe 16 is connected to an external pressurizing machine. It can be seen that the two ends of the oil inlet pipe 16 are respectively connected to the oil outlet pipe 14 and the external pressurizing machine for pressurizing the fluid.
[0027] like Figure 1 and Figure 8 As shown, in this embodiment, a pressure relief module 17 is provided on one side of the support frame 1, and a pressure relief pipe 18 is provided on the other end of the oil delivery pipe module 12. The two ends of the pressure relief pipe 18 are connected to the oil outlet pipe 14 and the pressure relief module 17, respectively. Therefore, the pressure relief pipe 18 and the pressure relief module 17 can be used to relieve pressure after the pressure test is completed.
[0028] like Figure 1 and Figure 2 As shown, in this embodiment, a first sensor 19 is provided on one side of the support frame 1, and the first sensor 19 is inductively coupled with the side corresponding to the pressure plate 7. A second sensor 20 is provided on one side of the U-shaped bracket 5, and the second sensor 20 is inductively coupled with the side of the side push block 152 away from the U-shaped bracket 5. Thus, it can be seen that the first sensor 19 and the second sensor 20 can transmit the downward pressing position and the side push position in real time, preventing the downward pressing assembly 2 and the side push limit assembly 15 from moving simultaneously and causing a collision.
[0029] The working principle of the present utility model is as follows: before the equipment is started, the external transmission mechanism moves the high-pressure warehouse body to the middle of the through groove 4 to complete the positioning, and several of the downward pressure cylinders 6 drive the high-pressure warehouse cover 3 to press down and connect with the sealing end of the high-pressure warehouse body. The first sensor 19 feedbacks the downward pressure situation. When the downward pressure seal is normal, several of the side thrust cylinders 153 drive the side thrust block 152 to move horizontally and move to the upper end of the pressure plate 7. The second sensor 20 feedbacks the side thrust limit situation. After the side thrust limit is completed, the external pressurizing machine passes the high-pressure fluid into the high-pressure warehouse body through the oil inlet pipe 16 and the oil outlet pipe 14, and the pressure increases. After the pressurization is completed, the pressure relief module 17 is started, and the high-pressure fluid flows out from the pressure relief pipe 18. The internal pressure of the high-pressure warehouse body returns to normal, and several of the side thrust cylinders 153 drive the side thrust block 152 to restore the initial position. The high-pressure warehouse cover 3 rises and separates, and the external transmission mechanism moves the high-pressure warehouse body to the next workstation, completing the downward pressure sealing and limiting of the high-pressure warehouse cover of the HPP equipment.
[0030] Although the embodiments of the present invention are described with practical solutions, they do not limit the meaning of the present invention. For those skilled in the art, it is obvious to modify the implementation scheme and combine it with other solutions based on this description.
