[0030] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0031] This embodiment provides a flat-pressure aseptic tube sealing machine that is easy to clean. As Figure 1-6 shown, the aseptic tube sealing machine includes a main body 1 of the aseptic tube sealing machine and a lower pressing plate 2 provided on the main body 1 of the aseptic tube sealing machine. An upper pressing plate 3 is hinged on the lower pressing plate 2;

[0032] Among them, a cavity is opened inside the upper pressing plate 3. A fixing plate 31 and a heat conducting plate 32 installed on the fixing plate 31 are provided on one side of the upper pressing plate 3 close to the lower pressing plate 2, and a heating element 33 is provided inside the cavity;

[0033] Two groups of fixing mechanisms 4 are equidistantly arranged inside the upper pressing plate 3;

[0034] The fixing mechanism 4 includes an assembly seat 41 arranged in the cavity of the upper pressing plate 3, fixing brackets 44 symmetrically arranged at both ends of the assembly seat 41, and an assembly block 51 arranged on the surface of the fixing plate 31 close to the upper pressing plate 3. An installation groove 48 corresponding to the assembly block 51 is formed on the surface of the assembly seat 41 close to the fixing plate 31. Movable blocks 43 are symmetrically arranged on the assembly seat 41. Accommodation grooves are symmetrically formed inside the assembly block 51. Limit blocks 52 and second springs 53 connected to the limit blocks 52 are slidably connected to the accommodation grooves respectively.

[0035] Specifically, the traditional single pressing plate is changed to a detachable pressing plate. The whole can be divided into a fixing plate 31 and a heat conducting plate 32 installed on the fixing plate 31, and an upper pressing plate 3 and a heating element 33 installed in the upper pressing plate 3. Among them, the heat conducting plate 32 and the heating element 33 are horizontally aligned. After installation, the bottom of the heat conducting plate 32 contacts the heating element 33 and heating work can be completed after being electrified. The installation groove 48 formed on the assembly seat 41 is mainly used for the insertion of the assembly block 51, which can not only play a role in calibration, but also realize the clamping and fixing function through the cooperation of the movable block 43 and the limit block 52. There is no need to use screws for fixing, and the installation method is convenient. A chamfer is formed at one end of the movable block 43 close to the reset cone plate 47, which is used to reduce friction when contacting the reset cone plate 47 and is convenient to be extruded. A chamfer is also formed at one end of the limit block 52 close to the assembly seat 41, which also plays a role in reducing friction and being convenient to be extruded when inserting into the installation groove 48. When inserted to the deepest position, the limit block 52 and the movable block 43 are at the coaxial position.

[0036] Ear plates 49 are symmetrically arranged on the assembly seat 41. A limit rod 45 for inserting through the ear plate 49 is fixedly installed on the fixing bracket 44. A first spring 46 is sleeved outside the limit rod 45, and one end of the first spring 46 is connected to the ear plate 49.

[0037] More specifically, the ear plates 49 at both ends of the assembly seat 41 are respectively sleeved with the limit rods 45 on the symmetrically distributed fixing brackets 44, and its main purpose is to play a role in upper and lower limit movement. At the same time, in cooperation with the first spring 46, the assembly seat 41 can be reset after being pressed.

[0038] The fixing mechanism 4 further includes a button seat 42 movably inserted into the upper pressing plate 3. One end of the button seat 42 close to the fixing plate 31 is fixedly connected to the assembly seat 41. One side of the assembly block 51 away from the assembly seat 41 is fixedly connected to an assembly frame 5, and one side of the assembly frame 5 away from the assembly block 51 is fixedly connected to the fixing plate 31.

[0039] It should be noted that the button base 42 is connected to the assembly base 41, mainly serving as a switch button for separating the fixed plate 31 and the upper pressure plate 3 in the later stage. By pressing the button base 42, the assembly base 41 and the movable block 43 are synchronously moved closer to the reset cone plate 47 until the movable block 43 pushes the limit block 52 into the interior of the assembly block 51 under the extrusion of the reset cone plate 47. At this time, the assembly block 51 and the assembly base 41 are no longer clamped and fixed, and the fixed plate 31 is lifted by the assembly base 41 to achieve the effect of being separated from the upper pressure plate 3. The assembly frame 5 plays a role in supporting and fixing the assembly block 51.

[0040] A reset cone plate 47 is fixedly installed on one side of the fixing frame 44 close to the assembly base 41, and the reset cone plate 47 is integrally formed with the fixing frame 44.

[0041] It is worth mentioning that the reset cone plate 47 is conical in shape, and the slope angle is larger as the distance from the assembly base 41 is farther. Its main function is to extrude the movable block 43 to push the limit block 52 into the interior of the assembly block 51.

[0042] During use, when it is necessary to separate the fixed plate 31 and the upper pressure plate 3 for deep cleaning of the heat conduction plate 32, manually flip the upper pressure plate 3 by ninety degrees on the lower pressure plate 2 so that the upper pressure plate 3 is perpendicular to the lower pressure plate 2. At this time, press the two button bases 42 simultaneously. The assembly base 41 and the movable block 43 located inside the upper pressure plate 3 are synchronously moved closer to the reset cone plate 47 until the movable block 43 pushes the limit block 52 into the interior of the assembly block 51 under the extrusion of the reset cone plate 47. The assembly block 51 and the assembly base 41 are no longer clamped and fixed, and the fixed plate 31 is lifted by the assembly base 41 to achieve the effect of being separated from the upper pressure plate 3. At this time, the fixed plate 31 is separated from the upper pressure plate 3 and protrudes a certain distance. The fixed plate 31 can be removed from the upper pressure plate 3 for cleaning operations. After the cleaning is completed, align the assembly block 51 below the fixed plate 31 with the installation groove 48 on the assembly base 41 and insert it. The absence of a protruding part between the fixed plate 31 and the upper pressure plate 3 represents successful installation.

[0043] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application, according to the technical solution and its concept of the present application, makes equivalent substitutions or changes, and should be covered by the protection scope of the present application.
