DETAILED DESCRIPTION
[0019] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.
[0020] See also Figure 1-8 The highly antibacterial rubber plug aseptic molding device provided by the embodiment of the present invention includes a frame 1 and also includes: A control mechanism 5 capable of vertical displacement along the frame 1; The cutting mechanism 6, several cutting mechanisms 6 are arranged at the lower part of the control mechanism 5, and the cutting mechanism 6 includes a pair of cutters 65. During the downward movement of the control mechanism 5, the cutting mechanism 6 has a first stroke and a second stroke. In the first stroke, the pair of cutters 65 are in an expanded state, and in the second stroke, the pair of cutters 65 are passively closed, so that the rubber plug can be centered and cut by the cutter 65.
[0021] In the embodiment of the present invention, the control mechanism 5 can be displaced in the vertical direction, and has a first stroke and a second stroke during the downward movement of the control structure. The cutter 65 is arranged at the lower part of the control mechanism 5. Therefore, when the control mechanism 5 moves downward, the cutter 65 will be driven to move downward. The position of the cutter 65 corresponds to the film to be cut. As the control mechanism 5 moves downward, when the lowest point of the cutter 65 is lower than the middle of the rubber plug, the control mechanism 5 will drive the cutter 65 to close gradually and passively. After being fully closed, the film is cut by continuously moving the control mechanism 5 downward, so as to achieve During the separation between the film and the rubber plug, the rubber plug can be centered by closing the cutter 65. Even if there is a certain offset between the size of the rubber plug and the cutter 65, the rubber plug can be forced into a position by closing the cutter 65. In this way, the rubber plug can be unloaded without cutting the film, thus saving the intermediate cutting steps. Moreover, a whole sheet of film only needs to be positioned once when placed before it can be cut, and the rubber strips formed after cutting are positioned multiple times respectively, thus greatly increasing the production efficiency.
[0022] In the embodiments of the present invention, refer to Figure 1-2 The frame 1 includes a support frame 11 and a base 12. The base 12 is fixedly installed at the lower part of the support frame 11. A material table 2 is slidably connected to the base 12, and the material table 2 is used for laying the film.
[0023] It comprises a first driving part 3, which is used for driving the material platform 2 to move in a horizontal direction.
[0024] The film is laid on the material table 2, and a pair of positioning blocks are provided on one side of the material table 2 to ensure that the position of the film is accurate. When laying, the material table 2 is pushed out by the first driving unit 3 to ensure safety.
[0025] In the embodiments of the present invention, please refer to Figure 4-7 The control mechanism 5 also includes a second driving part 4, a fixed plate 51, a force arm 52, a bottom plate 53, a sliding plate 54, a support spring 55, a cylinder 56, a first elastic member 57, and a push rod 58. The output end of the second driving part 4 is fixedly connected to the fixed plate 51, the force arm 52 is fixedly installed on both sides of the fixed plate 51, the bottom plate 53 is fixedly installed at the lower part of the force arm 52, the sliding plate 54 is slidably connected to the force arm 52, the support spring 55 is arranged between the sliding plate 54 and the bottom plate 53, the push rod 58 is slidably connected to the cylinder 56, and the first elastic member 57 applies an upward thrust to the push rod 58.
[0026] The cutting mechanism 6 also includes a guide sleeve 61, a column 62, a central axis 63, a connecting block 64, a guide rail 66, and a second elastic member 67. The guide sleeve 61 is fixedly mounted on the base plate 53, the column 62 is fixedly mounted on the sliding plate 54, the cutter 65 is hinged on the column 62, and the second elastic member 67 applies a thrust to the cutter 65 for unfolding.
[0027] The second driving part 4 extends outward, and the fixing plate 51 can be driven to move downward, and is in the first stroke at this time, until the bottom plate 53 moves to the position as shown in the figure. Figure 4 As shown, the second stroke begins at this time, the push rod 58 just contacts the sliding plate 54, and the bottom plate 53 continues to move downward. First, the elastic force of the first elastic member 57 is relatively large, which will apply an upward thrust to the sliding plate 54, so the support spring 55 is extended, and the gap between the sliding plate 54 and the bottom plate 53 increases, which will inevitably drive the column 62 to move upward, and the upward displacement of the column 62 will drive the cutter 65 to shrink in the guide sleeve 61. Under the pressure of the guide sleeve 61, the cutter 65 will close. When the cutter 65 is closed, the rubber plug can be centered. It should be noted that since the cutter 65 moves upward during the closing process, the first elastic member 57 will be compressed during this process to play a compensating role. In this way, while the gap between the sliding plate 54 and the bottom plate 53 increases, the height of the sliding plate 54 decreases. In this way, the cutter 65 increases in height compared to the bottom plate 53, and decreases in height relative to the rubber plug. In this way, the attached Figure 5 In the state shown in FIG. 1 , the cutter 65 just covers the outside of the rubber plug, and a limit block 59 is provided on one side of the force arm 52. The limit block 59 limits the maximum distance between the sliding plate 54 and the bottom plate 53. As the bottom plate 53 continues to move downward, the first elastic member 57 continues to be compressed, and the cutter 65 separates the film and the rubber plug. The second stroke ends to form the attached Figure 6 The state shown; subsequently, it needs to be lifted after the cutting is completed. At this time, the force arm 52 rises. Due to the elastic force of the film, it will be sleeved on the outside of the cutter 65 and move up with the cutter 65 until the force applied by the top rod 58 to the sliding plate 54 is reduced. Under the action of the gravity of the sliding plate 54, the distance between the sliding plate 54 and the bottom plate 53 is reduced, so that the cutter 65 moves downward compared to the guide sleeve 61 and loses the restriction of the guide sleeve 61, so that the cutter 65 is unfolded under the elastic force of the second elastic member 67. After the cutter 65 is unfolded, the rubber plug will fall onto the material table 2.
[0028] In another embodiment of the present invention, please refer to Figure 2 and Figure 7, and also includes a separation rod 7, which is fixedly installed on the frame 1. The separation rod 7 is arranged between two adjacent cutting mechanisms 6. When the fixed plate 51 continues to move upward, the film may be unable to separate from the cutter 65. The separation rod 7 blocks the waste film so that the film can be separated from the outside of the cutter 65. In this process, due to the elastic effect of the film, the cutter 65 is not fully unfolded before the film is separated. After the film is separated, the cutter 65 rebounds quickly under the action of the second elastic member 67, and a vibration effect is also generated to reduce the attachment at the edge of the cutter 65.
[0029] In the embodiment of the present invention, the upper part of the support spring 55 is fixedly connected to the sliding plate 54, and the lower part of the support spring 55 is fixedly connected to the bottom plate 53. The setting of the support spring 55 can also serve the purpose of pulling the sliding plate 54, avoiding the phenomenon that the first elastic member 57 is compressed too little after the top rod 58 hits the sliding plate 54, so as to ensure that the height of the cutter 65 is lowered.
[0030] In the embodiment of the present invention, a through hole is provided on the bottom plate 53. In the second stroke, the push rod 58 passes through the through hole and abuts against the sliding plate 54. The push rod 58 is avoided by the through hole.
[0031] In the embodiment of the present invention, the central shaft 63, the connecting block 64, and the guide rail 66 are further included. The central shaft 63 is fixedly mounted on the column 62. The connecting block 64 is fixedly mounted on the inner side of the cutter 65. The connecting block 64 and the central shaft 63 are rotatably connected. The guide rail 66 is fixedly mounted on the column 62. The guide rail 66 is set to be semicircular, and the center of the guide rail 66 and the rotation center of the cutter 65 are at the same position. The cutter 65 can be fixed by setting the connecting block 64 so that the cutter 65 can rotate around the central shaft 63. The second elastic member 67 is movably sleeved on the outside of the guide rail 66. The second elastic member 67 can apply thrust to the cutter 65 through the restriction of the guide rail 66.
[0032] In the embodiment of the present invention, the lower part of the guide sleeve 61 and the upper part of the cutter 65 are both provided with arc chamfers. The provision of the arc chamfers helps the cutter 65 to retract into the guide sleeve 61.
[0033] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
