Description

Technical Field

[0001] This utility model relates to the field of blow molding machine guide rails, and more specifically, to a stretch blow molding machine guide rail. Background Technology

[0002] The stretching guide is a key component for controlling the lifting speed of the stretching rod in a blow molding machine. Due to the characteristics of the preform material, the stretching speed is within a fixed range. When the single-mold capacity of the blow molding machine is large, the stretching descending guide is generally relatively gentle, i.e., it is used for blowing small bottles; when the single-mold capacity of the blow molding machine is small, the stretching descending guide is generally relatively steep, i.e., it is used for blowing large bottles.

[0003] Most current guide rails are fixed-length strips. However, in stretch blow molding machines, fixed-length guide rails are difficult to adapt to the adjustment needs of different bottle shapes or production scales. When it is necessary to produce taller or wider bottles, insufficient guide rail length may limit the movement range of the mold or stretching rod, resulting in limited production flexibility. How to invent a stretch blow molding machine guide rail to improve these problems has become an urgent problem to be solved by those skilled in the art. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a guide rail for a stretch blow molding machine, which aims to improve the problem that fixed-length guide rails are difficult to adapt to the adjustment needs of different bottle shapes or production scales. When it is necessary to produce taller or wider bottles, insufficient guide rail length may limit the movement range of the mold or stretching rod, resulting in limited production flexibility.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Example, refer to Figures 1-4 A guide rail for a stretch blow molding machine includes a guide rail 1. The guide rail 1 has two sets of locking blocks 2 on one side wall and two sets of locking grooves 4 on the other side wall that cooperate with the locking blocks 2. Each set of locking blocks 2 has insertion holes 3 on its opposite side wall. The guide rail 1 has a cavity 6 inside. The guide rail 1 also includes a latching mechanism 5: the latching mechanism 5 is located inside the cavity 6 and can latch onto the insertion holes 3, thereby fixing the locking blocks 2 in the locking grooves 4. This mechanism allows for the splicing of multiple sets of guide rails 1.

[0022] The latching mechanism 5 includes a fixing block 505 fixedly installed inside the cavity 6. Electromagnetic blocks 504 are provided on the upper and lower side walls of the fixing block 505. Two sets of movable plates 502 are slidably connected inside the cavity 6. Two sets of guide grooves are opened on the left and right side walls of the cavity 6. Guide blocks matching the guide grooves are provided on the left and right side walls of the two sets of movable plates 502. Under the action of the guide grooves and guide blocks, the movable plates 502 move more stably in the cavity 6. Magnet blocks 503 are provided on the opposite side walls of the two sets of movable plates 502. Insert rods 501 are provided on the side walls of the two sets of movable plates 502 away from each other. One end of the insert rod 501 moves through the inner side wall of the cavity 6 and cooperates with the insertion hole 3. Springs 500 are sleeved on the outer walls of the two sets of insert rods 501. One end of the spring 500 is connected to the side wall of the movable plate 502, and the other end of the spring 500 is connected to the inner side wall of the cavity 6.

[0023] It should be noted that the electromagnetic block 504 is electrically connected to the external power supply and controller. Therefore, when the electromagnetic block 504 is de-energized, the magnet block 503 separates from the electromagnetic block 504. Under the action of the spring force of the spring 500, the insertion rod 501 is driven to insert into the insertion hole 3 to achieve fixation.

[0024] Positioning holes are provided in the inner side of the card slot 4, away from the side wall. One end of the insertion rod 501 passes through the insertion hole 3 and cooperates with the positioning hole.

[0025] It should be noted that when splicing and installing the guide rail 1, the insertion rod 501 can pass through the insertion hole 3 and cooperate with the positioning hole, so as to better fix the card block 2 and achieve stable splicing of the guide rail 1.

[0026] Working principle: When the length of guide rail 1 needs to be extended during the stretch blow molding process, the locking block 2 is inserted into the locking slot 4. The external controller is controlled to de-energize the electromagnetic block 504 (initially, the electromagnetic block 504 is energized and the spring 500 is in a stretched state). Then, under the action of the spring 500, the insertion rod 501 is driven to insert into the positioning hole through the insertion hole 3, thereby better fixing the locking block 2 and achieving stable splicing of guide rail 1.

[0027] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0028] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
