[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0025] See also Figure 1-6 The utility model discloses a multi-head single-controllable pressure-maintaining machine, comprising an electric control cabinet 1 and a product placement platform 2 arranged on the top of the electric control cabinet 1. A mechanical cover 3 is arranged on the top of the electric control cabinet 1, and a multi-head pressure-maintaining mechanism 4 located on the top of the product placement platform 2 is arranged in the mechanical cover 3.

[0026] The multi-pressure head pressure maintaining mechanism 4 is composed of multiple pressure maintaining components, each of which includes a pressure component 41 for pressurizing the product on the top of the product placement platform 2 and a lifting component 42 for driving the pressure component 41 to move toward and away from one side of the product placement platform 2.

[0027] The utility model forms a multi-pressure head pressure-maintaining mechanism 4 through multiple pressure-maintaining components, so that the multiple pressure-maintaining components do not interfere with each other, and multiple pressure-maintaining components can be pressure-maintained at the same time. The pressure-maintaining time and pressure of each pressure-maintaining component can also be controlled separately. It can be used in many occasions, is not prone to errors, and has a wide range of applications.

[0028] In one embodiment, the hood 3 includes a top plate, a plurality of columns are provided between the top plate and the electrical control cabinet 1, and the lifting assembly 42 is provided at the bottom of the top plate;

[0029] The lifting assembly 42 includes a mounting plate 421 located at the bottom of the top plate, two connecting plates 422 are arranged between the mounting plate 421 and the top plate, a motor 423 is arranged at the bottom of the mounting plate 421 and passes through the mounting plate 421, and the output end of the motor 423 is provided with a driving wheel 424 located at the top of the mounting plate 421, a screw rod 425 is rotatably arranged at the bottom of the mounting plate 421 and passes through the mounting plate 421, a driven wheel 426 is arranged at the top of the screw rod 425 and is located at the top of the mounting plate 421, a synchronous belt 427 is arranged between the driven wheel 426 and the driving wheel 424, and a first guide rail 428 is also provided at the bottom of the mounting plate 421 between the motor 423 and the screw rod 425, and a screw rod support 429 is provided on the screw rod 425 and is driven by the screw rod 425 to move up and down along the first guide rail 428, and the pressurizing assembly 41 is arranged on the screw rod support 429.

[0030] This design places a PLC controller in the electric control cabinet 1 and connects the motor 423 of each lifting component 42 to the PLC controller, so that the PLC controller can automatically control the start and stop time of the motor 423 on different lifting components 42. By changing the start and stop time of the motor 423, the pressure holding time after the screw support 429 drives the pressurizing component 41 to move downward is changed, thereby achieving precise pressing time control of each pressurizing component 41, and compared with the existing cylinder lifting, it will not be affected by factors such as unstable air pressure.

[0031] In the specific implementation, a sealing plate is provided between the top plate and the electric control cabinet 1 for blocking three sides of the multi-pressure head pressure maintaining mechanism 4, leaving only one side for loading and unloading materials, and a safety grating is provided on this side. When the safety grating detects an object, the multi-pressure head pressure maintaining mechanism 4 cannot be started, thereby effectively improving the safety of use.

[0032] In one embodiment, the motor 423 is slidably disposed at the bottom of the mounting plate 421 , and a tensioning assembly 5 is disposed at the bottom of the mounting plate 421 for driving the motor 423 to move toward and away from the screw rod 425 ;

[0033] The tensioning assembly 5 consists of a tensioning block 51, a tensioning screw 52 and a nut 53. The tensioning block 51 is arranged at the bottom of the mounting plate 421 and is located on the side of the motor 423 away from the screw rod 425. The tensioning screw 52 is fixedly arranged on the side of the motor 423 close to the tensioning block 51, and one end of the tensioning screw 52 passes through the tensioning block 51. The nut 53 is arranged on the tensioning screw 52 and is located on the side of the tensioning block 51 away from the motor 423.

[0034] With this design, the position of the nut 53 on the tensioning screw 52 is changed by rotating the nut 53 forward and reversely. When the distance between the nut 53 and the motor 423 is far, it is convenient for the synchronous belt 427 to be sleeved on the driven pulley 426 and the driving pulley 424. After the synchronous belt 427 is installed, the nut 53 is turned close to the motor 423 to move the motor 423 away from the screw rod 425, thereby increasing the distance between the driven pulley 426 and the driving pulley 424, tightening the synchronous belt 427, and ensuring that the synchronous belt 427 can work stably.

[0035] In one embodiment, the pressurizing assembly 41 includes a hook plate 411 and a second guide rail 412 arranged on the screw support 429, the second guide rail 412 is located at the bottom of the hook plate 411, and a pressure sensor 413 is provided at the bottom of the hook plate 411. The second guide rail 412 is provided with a first slider 414 that can move up and down along the second guide rail 412 and a second slider 415 located at the bottom of the first slider 414. The first slider 414 is provided with a guide rod 416 that is inserted into the second slider 415. A compression spring 417 is provided between the first slider 414 and the second slider 415 and is sleeved on the outside of the guide rod 416. The bottom of the second slider 415 is detachably provided with a pressure head 418.

[0036] With this design, after the screw support 429 moves downward to drive the pressure head 418 to contact the workpiece being processed, the continued downward movement of the screw support 429 will cause the first slider 414 to squeeze the compression spring 417, and then the first slider 414 will be squeezed by the reaction force of the compression spring 417 to squeeze the pressure sensor 413. By setting the threshold value of the pressure sensor 413 on different pressurizing components 41, the lifting component 42 can be controlled to continue to move downward after reaching the threshold value, thereby ensuring the pressure accuracy when different pressure-maintaining components are pressed together.

[0037] In one embodiment, the hook plate 411 is composed of a connecting section connected to the screw support 429, a vertical section arranged at the bottom of the connecting section, and a hook section arranged on the side of the vertical section close to the second guide rail 412. The first slider 414 is provided with a protrusion located between the connecting section and the hook section. When the protrusion abuts against the hook section, the first slider 414 does not contact the pressure sensor 413.

[0038] This design ensures that when the pressurizing assembly 41 is not in contact with the workpiece, the first slider 414 will not fall off the second guide rail 412 due to gravity. It has a simple structure, a small number of parts, and low cost.

[0039] See also Figure 2 In a specific implementation, multiple pressure-maintaining components can be arranged in a staggered manner, thereby improving space utilization and reducing the overall volume of the multi-pressure-maintaining mechanism 4 without changing the position of the pressure head 418.

[0040] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0041] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features specified as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0042] In addition, "plurality" means two or more.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
