DETAILED DESCRIPTION

[0022] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] like Figure 1-3 As shown together, this embodiment is about a spin-melting mechanism for a filter membrane end cap and a central tube, which has two spin-melting processing positions operating simultaneously, and can select and operate end caps of different sizes at the same time, and has strong compatibility.

[0024] Specifically, it includes a first workstation 1 and a second workstation 2 which are respectively slidably connected to the front end platform and longitudinally matched. The longitudinal matching means that the second workstation 2 is installed on one side of the first workstation 1 and the side is closer to the spin melting processing position. The first workstation 1 and the second workstation 2 cooperate together to form two spin melting processing positions arranged in the horizontal direction. The two spin melting processing positions are respectively on the left and right sides of the horizontal position. The structural settings of the two spin melting processing positions are exactly the same, which is hereby explained.

[0025] The first station 1 and the second station 2 each form a sliding connection with the front platform through the cooperation of the slider 3 and the slide rail 4. The slider 3 is arranged at the bottom of the first station 1 and the second station 2, and the slide rail 4 is arranged on the front platform.

[0026] The lower side of the first station 1 is connected to the push cylinder 12 through the push plate 32, and the push cylinder 12 is implemented in a manner of changing the longitudinal position of the first station 1, so the output end of the push cylinder 12 faces the side of the spin melting processing station. In order to enhance the pushing ability, in this embodiment, the number of the push cylinders 12 is two, and the two push cylinders 12 are symmetrically arranged, which is hereby explained; the upper side of the first station 1 is connected to a first motor 17 located in the middle position in the horizontal direction through a plate, and the output end of the first motor 17 is connected to a ball screw 15 through a coupling, and the ball screw 15 passes through a ball screw bearing 16 installed on a second connecting plate 19 of the second station 2, and the first motor 17 is implemented in a manner of changing the longitudinal position of the second station 2 through the ball screw 15;

[0027] The upper side of the first station 1 is also equipped with core-pulling cylinders 5 located on both sides, the output end of the core-pulling cylinder 5 is connected to the core-pulling 6 extending to the rotary melting processing position, the core-pulling 6 is strung in the tube expander 10, the core-pulling 6 is connected to the core-pulling connecting block 7 close to the core-pulling cylinder 5, one end of the tube expander 10 is connected to the first connecting plate 8 installed on the first station 1 through the tube expander fixing block 9, the circumferential outer periphery of the tube expander 10 is sleeved with a connecting pipe 11, and the connecting pipe 11 is rotatably connected through the connecting pipe bearing seat 23 located on the second connecting plate 19;

[0028] The portion of the connecting tube 11 near the free end of the tube expander 10 is fixedly connected to the end cover fixing seat 27, and the end cover fixing seat 27 is separated from the clamping cylinder 24 by a spacer plate 25. The clamping cylinder 24 is installed on the spacer plate 25. A connecting block 28 is also provided between the spacer plate 25 and the end cover fixing seat 27. The connecting block 28 forms a direct connection relationship with the clamping cylinder 24. The end cover fixing seat 27 is connected to a plurality of end cover clamping blocks 30. In this embodiment, four end cover clamping blocks 30 are preferably provided. The end cover clamping blocks 30 are connected to the connecting blocks 28 through a connecting rod 29 and a rotating shaft. It can be understood that the connecting block 28 is connected to the connecting rod 29 through a rotating shaft, and the connecting rod 29 is also connected to the end cover clamping block 30 through a rotating shaft, and as shown in FIG. Figure 3 As shown, the connecting rod 29 in this embodiment is a multi-branch structure, that is, a plurality of branch connecting rods are connected to each other through a rotating shaft.

[0029] The second workstation 2 is equipped with a second motor 18 installed at the highest point in the vertical direction through a second connecting plate 19. The second motor 18 is indirectly installed by connecting the motor connecting rod 20 to the second connecting plate 19. In the present embodiment, for the sake of stable installation, the number of motor connecting rods 20 is preferably four. It can be understood that the four motor connecting rods 20 are respectively assembled at the four corners of the second motor 18. Moreover, in order to further enhance the stability of the installation, it can also be implemented by adding a connecting plate between the motor connecting rod 20 and the second motor 18.

[0030] Preferably, the output end of the second motor 18 is arranged toward the side of the spin melting processing position, and the output end of the second motor 18 is equipped with a synchronous wheel 21. Not only that, the two connecting tubes 11 are also connected with the synchronous wheels 21, and the synchronous wheels 21 are matched with synchronous belts 22. The synchronous belts 22 are implemented in a manner of tensioning through three synchronous wheels 21 to form a triangle. The driving force of the second motor 18 is used to output the synchronous wheel 21 to rotate, and the synchronous wheel 21 drives the synchronous belt 22 to drive the two connecting tubes 11 to rotate.

[0031] The overall structure of this embodiment can be arranged at both ends of the central tube 31 at the same time, thereby facilitating the spin melting process of the central tube 31 and the end cover 33 .

[0032] The working principle of this embodiment is as follows:

[0033] First, the end cap 33 to be spin-melted is installed on the end cap fixing seat 27. It should be noted that the end cap 33 can be installed on the end cap fixing seat 27 on the adapting side of the two spin-melting processing positions. Then, the clamping cylinder 24 is actuated to push the connecting block 28 forward, and then the end cap 33 is clamped by the end cap clamping block 30, so that the end cap 33 can rotate together with the end cap fixing seat 27. The connection state is completed;

[0034] Secondly, the push cylinder 12 is actuated to move the first station 1 and its entire device toward the side of the spin melting processing station. During this process, the tube expander 10 penetrates into the center tube 31, and then the core pulling cylinder 5 is actuated to pull the core pulling 6 backward so that the tube expander 10 expands and tightens the center tube 31.

[0035] Again, the second motor 18 is started to drive the synchronous wheel 21 and the synchronous belt 22 to synchronously drive to drive the connecting pipe 11 to rotate, thereby driving the end cover fixing seat 27 to rotate, and the end cover 33 rotates along with the end cover fixing seat 27; at the same time, the first motor 17 is started to drive the ball screw 15 to rotate to drive the second connecting plate 19 to move forward. It can be understood that the forward movement of the second connecting plate 19 drives the second station 2 and its entire device to move toward the side of the spin melting processing station, thereby causing the end cover 33 to rotate and move forward at the same time;

[0036] Finally, the end cap 33 moves forward and generates heat under the friction with the central tube 31 due to the mechanical rotation force, so that the two are heated up and then welded. Then, the first motor 17 and the second motor 18 are turned off, and the spin-melting process is completed.

[0037] The end cover 33 can be disassembled by reversing the above-mentioned action principle, which is specially explained.

[0038] In this way, the rotary melting mechanism of the filter membrane end cap and the central tube disclosed in the utility model adopts an external clamping method to fix the end cap, which will not cause damage to the connecting reinforcing ribs, and the double-station structure can be selected according to the size of the end cap of different models, and has strong versatility. The central tube is fixed by a tube expander, which has a good fixing effect, a tight fixing effect and will not damage the outer surface of the central tube.

[0039] The above implementation modes are not limitations of the present invention, and the present invention is not limited to the above examples. Any changes, modifications, additions or substitutions made by technicians in this technical field within the technical solution of the present invention also belong to the protection scope of the present invention.
