[0020] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0021] The following description, with reference to the accompanying drawings, describes an integrated blow-fill-seal machine with mold closing origin detection according to an embodiment of this application.

[0022] According to an embodiment of this utility model, a blow-fill-seal integrated machine with mold closing origin detection is provided. Please refer to [link / reference]. Figures 1-6 It includes: a frame 1, a transmission assembly (not marked in the figure), a detection assembly 7, a mold assembly (not marked in the figure), and a mold closing frame 6. The transmission assembly includes a drive shaft 5, a drive sprocket 4, a driven sprocket 8, a drive wheel 72, a driven wheel 75, a timing belt 71, a mounting bracket 74, a tension wheel 73, and a coupling 78. The detection assembly 7 includes a detection component 77, a verification component 791, a rotating shaft 76, and an encoder 79. The mold assembly includes a chain 3 and a mold 2.

[0023] Specifically, such as Figure 1 As shown, multiple sets of chains 3 are connected end to end to form a closed mold chain (not marked in the figure). The drive sprocket 4 is installed on the frame 1 below in the vertical direction. The drive sprocket 4 can rotate around its axis on the frame 1. The drive sprocket 4 is provided with the first gear 41 and the first slot 42; Figure 1 , Figure 2As shown, the drive shaft 5 is mounted on the frame 1 and can rotate around its axis on the frame 1. The drive shaft 5 is equipped with a second gear 51. The drive sprocket 4 and the drive shaft 5 are connected by meshing of the first gear 41 and the second gear 51, causing the drive shaft 5 to drive the drive sprocket 4 to rotate. Figure 1 As shown, the driven sprocket 8 is mounted on the frame 1 and is located above the driving sprocket 4 in the vertical direction. The driven sprocket 8 is provided with the second slot 81; Figure 1 , Figure 6 As shown, one end of the mold chain is fitted into the first slot 42 on the driving sprocket 4, and the other end of the mold chain is fitted into the second slot 81 on the driven sprocket 8. By driving the driving shaft 5 to rotate, one mold chain rotates clockwise, and the other mold chain rotates counterclockwise; Figure 1 As shown, multiple molds 2 are respectively mounted on two mold chains, and the molds 2 rotate smoothly with the mold chains.

[0024] like Figure 1 , Figure 4 As shown, the mold clamping frame 6 is mounted on the frame 1 and located between the driving sprocket 4 and the driven sprocket 8. The mold clamping frame 6 is provided with a first guide surface 61 and a second guide surface 62. The mold chain drives the mold 2 to rotate during rotation, and each mold 2 is provided with one or more rollers 21. The mold 2 slides through the first guide surface 61 and the second guide surface 62 in sequence via the rollers 21. The second guide surface 62 extends along a first direction (vertical direction), and the first guide surface 61 and the second guide surface 62 form an angle.

[0025] like Figure 1 , Figure 2 As shown, the second gear 51 on the drive shaft 5 meshes with the first gear 41 on the drive sprocket 4, the drive shaft 5 drives the drive sprocket 4 to rotate, one end of the drive shaft 5 passes through the inner hole of the drive wheel 72, and the drive shaft 5 is fixedly connected to the drive wheel 72, the drive shaft 5 drives the drive wheel 72 to rotate; as Figure 2 , Figure 3As shown, one end of the rotating shaft 76 is mounted on the frame 1, and the rotating shaft 76 can rotate around its axis on the frame 1. The other end of the rotating shaft 76 is equipped with the driven wheel 75, the synchronous belt 71, the origin calibration disc, and the coupling 78. The driven wheel 75 is fixedly mounted on the rotating shaft 76 and rotates with the rotating shaft 76. The synchronous belt 71 is connected to the driven wheel 75 and drives the driven wheel 75 to rotate, thereby driving the rotating shaft 76 to rotate. The rotating shaft 76 is fixed in the inner hole of the coupling 78. The calibration component 791 is mounted on the rotating shaft 76 and located on the end face of the coupling 78. The calibration component 791 can rotate around its axis. The calibration component 791 is provided with a detection part. The calibration component 791 can be set as an origin calibration disc, and the detection part is set as a light-transmitting slit provided on the origin calibration disc.

[0026] like Figure 2 , Figure 3 As shown, the mounting bracket 74 is mounted on the frame 1 and located between the drive wheel 72 and the rotating shaft 76. The mounting bracket 74 can be adjusted at the mounting angle on the frame 1. The tension wheel 73 is mounted on the mounting bracket 74 and can rotate around its axis on the mounting bracket 74. The synchronous belt 71 is connected to the tension wheel 73 and the drive wheel 72. The tension of the synchronous belt 71 can be adjusted by adjusting the angle of the mounting bracket 74.

[0027] like Figure 2 , Figure 3 As shown, the encoder 79 is fixed on the frame 1, and the shaft end of the encoder 79 is fixed in the end hole of the coupling 78 away from the mold assembly. The detection element 77 is installed on the frame 1, wherein the detection element 77 can be set as a photoelectric sensor, and the U-shaped groove of the photoelectric sensor spans across both sides of the calibration element 791; the drive shaft 5 is driven to rotate, so that the drive shaft 5 drives one of the mold chains to rotate clockwise and one of the mold chains to rotate counterclockwise, and drives the encoder 79 and the calibration element 791 to rotate through the drive wheel 72.

[0028] In other words, such as Figures 1-6As shown, when the mold 2 is disassembled and assembled each time, the mold 2 of the blow-fill-seal integrated machine with mold closing origin detection needs to reset the mold closing origin position. In manual mode, the drive shaft 5 is driven to rotate counterclockwise (or clockwise). Through the meshing between the second gear 51 on the drive shaft 5 and the first gear 41 on one of the drive sprockets 4, one of the drive sprockets 4 is driven to rotate clockwise (or counterclockwise), causing the other drive sprocket 4 to rotate counterclockwise (or clockwise). The two drive sprockets 4 are symmetrically mounted on the frame 1, and the two first gears 41 on the two drive sprockets 4 mesh with each other. That is, one second gear 51 meshes with the first gear 41 and the other second gear 51 at the same time, so that the drive shaft 5 can drive the two drive sprockets 4 to rotate at the same time.

[0029] One of the drive sprockets 4 causes the mold chain connected to it to rotate clockwise, and the other drive sprocket 4 causes the mold chain connected to it to rotate counterclockwise. When the molds 2 on the two mold chains gradually move downward in the middle position, the rollers 21 on the molds 2 first contact the first guide surface 61 on the mold clamping frame 6. At this time, the two parts of the molds 2 on the left and right mold chains gradually close, but are not yet fully closed. Until the rollers 21 on the left and right parts of the molds 2 just contact the second guide surface 62 on the mold clamping frame 6, the left and right parts of the molds 2 are just fully closed, and the inching operation stops.

[0030] Furthermore, loosen the fastening screws on the coupling 78 near the side of the calibration component 791, manually rotate the coupling 78 so that the detection part on the calibration component 791 is exactly located in the U-shaped groove of the detection component 77, and the light beam on the detection component 77 can pass through the detection part on the calibration component 791, tighten the fastening screws on the coupling 78, and at the same time, the encoder 79 records the position state at this time and sets it as the origin position. When the rollers 21 of each set of molds 2 on the two mold chains just move to the second guide surface 62 of the mold clamping frame 6, the detection part on the verification component 791 is located in the U-shaped groove of the detection component 77, and the light beam on the detection component 77 can pass through the light-transmitting slit on the verification component 791. At this time, the encoder 79 and the detection component 77 send signals to the blow-fill-seal equipment to execute the filling action; that is, when the rollers 21 of each set of left and right molds 2 run to the second guide surface 62 of the mold clamping frame 6, the encoder 79 and the detection component 77 will send signals to the blow-fill-seal equipment to repeatedly execute the filling action, so as to realize the continuous automatic production of the blow-fill-seal equipment.

[0031] In summary, the blow-fill-seal integrated machine with mold closing origin detection of this utility model can not only accurately reflect the position status of each set of molds 2 when they are closed, but also make debugging and setting simple and convenient, saving time and effort. It can reduce the debugging and maintenance time and labor costs of the blow-fill-seal integrated machine and improve economic efficiency.
