New description: [New technical field] 2 to the system is related to the technical field of preform conveying of the blowing machine, especially one. The structure of 35 single, the action is indeed correct to change the distance between the preforms and the distance between the devices. [Prior Art] The bottle blowing machine for thickening _ production of PET, etc., the structure usually includes: conveying unit, heating unit, blow molding unit and finished product 亓 二 二 二 二 二 二 二 二The material unit is sent to the conveying degree, and the German single-handed 70-send bottle embryo is heated by the heating unit to a predetermined temperature. The blow molding is carried out in the mold of the finished product, and finally the blow-off is 70. The completed finished product is delivered. Efficiency, the blow molding unit often has a number of side-by-side settings, so that each preform is sent to the desired position of the mold between the two molds. In order to make the preforms be blown into the blow molding, the distance between the preforms and the molds can be transported, such as the patent in China. Announcement No. 2 is the same as the invention patent of the f-mold forming device and forming method. Blowing No. 573 However, when the conveying unit is in the distance between the molds, there is a considerable opening between the two adjacent preforms by heating the single and the distance, which makes the heating efficiency of the heating M396199 relatively poor. In other words, if the preform is delivered one by one through the heating unit, there will be better heating efficiency. Therefore, some blow molding machines are designed to transfer the preforms in a shape of one of the preforms, such as the invention patent of the "Biaxially-stretched 11-person plastic molding device" of China Patent Publication No. 453945. This is an example. Although the preform can be transported one by one, although the heating efficiency can be better, before the preform is sent to the blow molding unit, the spacing of the preforms must be expanded to the same mold by another mechanism or device. The distance between the preforms can be fed into the blow molding unit. Of course, such a "pitch expansion mechanism" is also disclosed in the invention patent of "Biaxial Stretch Blow Molding Apparatus" No. 453945. Please refer to FIG. 8 to FIG. 1 , FIG. 8 is a schematic plan view of the spacing expansion mechanism disposed in the blow molding machine; FIG. 9 is a schematic side view of the spacing expansion mechanism disposed in the blow molding machine; The map is a schematic diagram of the spacing expansion mechanism after expanding the spacing. The pitch expansion mechanism 8 is disposed between the heating unit 72 and the blow molding unit 73 along the guide rail 711 of the transport unit 71. The pitch expansion mechanism 8 is the end of the support arm 91 disposed on the base 9, and has a support plate 81 which is driven to move in a direction perpendicular to the guide 711 by the all-wheel cylinder 82. The support plate 81 is provided with a linear guide 83 for arranging the four conveying elements 841 to 844, and the spacing expansion mechanism 8 is provided with a retractable zooming mechanism 85 along the direction of the guide 711. The zooming mechanism 85 is composed of a The linear motion cylinder 86 disposed on the support plate 81 is driven to extend or contract, and each of the conveying elements 841 to 844 is pivotally connected to each of the joint points M396199 851 to 854 of the zoom mechanism 85, and the conveying member 844 is fixed thereto. On the support plate 81, the piston rod 861 of the direct acting cylinder 86 is connected to the conveying member 841. The front ends of the respective conveying members 841 to 844 respectively have a groove 845 to 848 for the receiving and conveying unit 71 to carry the carrier 74 carrying the preform p. The operation of the pitch expansion mechanism 8 is as follows. When the transport unit 71 sends the carrier 74 carrying the preform P, the direct acting cylinder 82 pushes the support plate 81 toward the guide rail 711, and the slots 745-1848 of the front ends of the respective transport members 841 to 844 receive a carrier 74, respectively. That is, the state shown in Fig. 9. Next, the linear motion cylinder 86 drives the scaling mechanism 85 to extend, so that the conveying members 841 to 843 slide along the linear guide 83 to increase the distance between the carriers 74 as shown in Fig. 1 . Then, the linear motion cylinder 82 pulls the support plate 81 back to disengage the transport elements 841 to 844 from the carrier 74, and then the other carriers 74 of the transport unit 71 feed the pitch-expanded carriers 74 into the blow molding unit. 73, finally, the linear motion cylinder 86 drives the zoom mechanism 85 to retract to the initial state of each of the conveying elements 841 to 844, thus completing the work of one-way spacing expansion.
於導 路徑的巡迴移動， 由兩支直動氣缸82、86依序驅動作矩形 因此其整體結構較為交錯複雜。 而且氣Μ缸型態的直動氣缸雖然具有動作速度快的優The traveling movement of the guide path is sequentially driven by the two linear cylinders 82 and 86 as a rectangle, so that the overall structure is relatively complicated. Moreover, the direct-acting cylinder of the gas cylinder type has an excellent speed of movement.
