[0032] The technical solution of the utility model is described in detail below through the accompanying drawings and specific embodiments:

[0033] Please refer to Figures 1 to 4 The present embodiment discloses a multi-pressing head pressure-maintaining mechanism, including a lifting bracket 100 and a presser module 200; a slide cylinder 130 is installed on the lifting bracket 100; multiple presser modules 200 are connected to the output end of the slide cylinder 130, and gaps are left between the multiple presser modules 200. The presser module 200 includes a presser 210, a counterweight 220, a linear guide 230 and a support plate 240. The presser 210 is installed under the support plate 240, and several counterweights 220 are installed on the support plate 240. The linear guide 230 is installed on the side of the support plate 240. The slide cylinder 130 provides power for the movement of the presser module 200, drives the presser module 200 to rise and fall, and switches between the initial state and the downward pressure state. The slide cylinder 130 retracts and drives multiple pressure head modules 200 to descend together. When the pressure head 210 of the pressure head module 200 touches the pressure holding surface, the pressure head module 200 stops moving and starts to hold pressure; other pressure head modules 200 continue to descend and move relatively until all pressure head modules 200 have touched the pressure holding surface and perform pressure holding. The pressure head module 200 adopts a split type, which eliminates the mutual influence between each pressure head 210, reduces the volume of the overall structure, simplifies the processing of parts, and achieves precise pressure holding and easy adjustment; solves the problem that the pressure holding effect is affected by the height difference of multiple groups of planes due to tolerance or pressure deformation and other factors, and can eliminate the mutual influence of multiple groups of planes during pressure holding; meets the pressure holding needs of multiple groups of pressure holding surfaces of different heights, and can automatically adapt to the height change to ensure that the pressure remains unchanged when the pressure surface is deformed downward after being compressed.

[0034] Please refer to Figure 2 The lifting bracket 100 includes a vertical plate 110 and a connecting plate 120, and a slide cylinder 130 is installed on the vertical plate 110. The slide cylinder 130 provides power for the movement of the pressure head module 200, drives the pressure head module 200 to rise and fall, and switches between the initial state and the downward pressing state.

[0035] Please refer to Figure 1, the output end of the slide cylinder 130 is connected to the connecting plate 120. The slide cylinder 130 retracts and drives the multiple ram modules 200 to descend together. When the ram 210 of the ram module 200 touches the pressure holding surface, the ram module 200 stops moving and starts to hold the pressure. The slide cylinder 130 continues to descend until all the ram modules 200 have performed the pressure holding.

[0036] Please refer to Figure 2 In some embodiments, the connecting plate 120 is further provided with a buffer rod 121, and the installation position of the buffer rod 121 matches the position of the vertical plate 110. When the slide cylinder 130 drives the pressure head module 200 to descend, the buffer rod 121 plays a buffering role.

[0037] Please refer to Figure 1 The connecting plate 120 is vertically connected to the mounting plate 250, and the mounting plate 250 is vertically and parallelly arranged with the supporting plate 240. The multiple pressing head modules 200 are all mounted on the mounting plate 250, so that the slide cylinder 130 drives the multiple pressing head modules 200 to rise and fall.

[0038] Please refer to Figure 3 and Figure 4 The counterweight 220 includes a counterweight block 221 and a guide rod 222. The counterweight block 221 is provided with a through hole, and the counterweight block 221 is sleeved on the guide rod 222 through the through hole. The spliced ​​counterweight method is adopted to reduce the processing difficulty and cost of the structure, and also provide a margin for adjusting the position of the pressure head 210; counterweight blocks of different weights are stacked according to the pressure required for pressure maintenance.

[0039] Please refer to Figure 5 The support plate 240 is an L-shaped structure, the pressure head 210 is installed below the support plate 240, and a plurality of counterweights 220 are installed above the support plate 240.

[0040] Please refer to Figure 6 and Figure 7 The pressure head 210 includes a fixing seat 211 and a rubber head 212. The rubber head 212 is installed under the fixing seat 211 and is provided with a profiling groove 213. The fixing seat 211 and the rubber head 212 are designed separately, and the rubber head 212 can be installed and removed independently; the size of the profiling groove 213 is adapted to the specification size of the product to be pressurized, and the rubber head 212 is in direct contact with the product, has a certain anti-static performance, and can be fine-tuned for calibration.

[0041] Please refer to Figure 7 The fixing seat 211 is provided with a mounting hole 214, and the pressing head 210 is mounted below the supporting plate 240 through the mounting hole 214. When part of the pressing head 210 is worn and damaged, it is convenient to replace a new pressing head 210.

[0042] This embodiment also discloses a pressure maintaining device, including the above-mentioned multi-pressure head pressure maintaining mechanism.

[0043] When the multi-pressure-maintaining mechanism is in the initial state, the slide cylinder 130 is in the extended state and maintained. The slide cylinder 130 provides power for the movement of the pressure head module 200, drives the pressure head module 200 to rise and fall, and switches between the initial state and the downward pressure state. The output end of the slide cylinder 130 is connected to the connecting plate 120, and the slide cylinder 130 retracts to drive multiple pressure head modules 200 to descend together; when the pressure head 210 of the pressure head module 200 touches the pressure holding surface, the pressure head module 200 stops moving and starts to maintain pressure; other pressure head modules 200 continue to descend and move relatively until all pressure head modules 200 have all touched the pressure holding surface and perform pressure maintenance. After the pressure maintenance is completed, the slide cylinder 130 drives the mounting plate 250 to lift all the pressure head modules 200, and the pressure head 210 leaves the product. The pressure head module 200 adopts a split type, which eliminates the mutual influence between each pressure head 210, reduces the volume of the overall structure, simplifies the processing of parts, achieves accurate pressure maintenance and easy adjustment; solves the problem that the pressure maintenance effect is affected by the height difference of multiple groups of pressure planes in the same direction due to tolerance or pressure deformation and other factors, and can eliminate the mutual influence of multiple groups of planes during pressure maintenance; meets the pressure maintenance needs of multiple groups of pressure maintenance surfaces of different heights, and can automatically adapt to the height change to ensure that the pressure remains unchanged when the pressure surface is deformed downward after being compressed. The use of a spliced ​​counterweight platform reduces the difficulty and cost of structural processing, and also provides a margin for adjusting the position of the pressure head; the structure is compact, the cantilever length is reduced, and the structural rigidity is increased.
