Description

Technical Field

[0001] The utility model relates to the technical field of heating devices, in particular to a device for solving the problem of PET bottleneck material accumulation and light condensing rod. Background Technique

[0002] PET plastic bottles are not only widely used for packaging carbonated beverages, drinking water, fruit juices, enzymes, tea beverages, etc., and are the most widely used beverage packaging today, but also widely used in many fields such as food, chemical, and pharmaceutical packaging. There are obvious ring marks on the accumulated materials at the necks of some PET empty bottles. In the production process, if the materials at the bottle shoulders have to be distributed, the heating power of the upper part of the preform needs to be very high. Since the high temperature will cause the deformation of the preform mouth, the deformation of the preform mouth will affect the sealing performance, which is not conducive to the actual production of PET plastic bottles. When the materials at the shoulders are evenly distributed, the top pressure of the empty bottle may be insufficient, and the insufficient top pressure will cause the mouth of the bottle to be indented under force. There is no suitable preform on the market, and it takes a long time and costs a high mold fee for the preform factory to customize new preforms. For high-shoulder bottle types, when there is no suitable preform type for matching, to keep the distribution of the preform materials at the shoulders uniform and the top pressure up to standard, it is necessary to use heating lamps to isolate and direct heat the preform.

[0003] The existing production heating device for PET bottleneck material accumulation is not convenient for flexible adjustment. In actual production, different high-shoulder bottle types provided by customers will be encountered. The heating device for PET bottleneck material accumulation is not convenient for flexible adjustment according to the actual production bottle type, which is not conducive to realizing the directional heating of materials. Therefore, the technical personnel in this field provide a device for solving the problem of PET bottleneck material accumulation and light condensing rod to solve the problems raised in the above background technique.

Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1 to 4 , in the embodiment of the present utility model, a device for solving the problem of light condensing rod for PET bottleneck accumulation includes a support frame. A plurality of groups of heating components arranged in parallel and at equal distances are installed on the back of the support frame. Chutes 1 are respectively opened inside both sides of the support frame. A directional component for condensing light on one group of heating components is installed inside the two chutes 1. A driving component for adjusting and positioning the corresponding position of the directional component inside the support frame is installed on one side of the support frame.

[0022] During use, the support frame is installed at the corresponding position on the PET plastic bottle production line. The heating components can be used to heat the PET plastic bottles. And a directional component for condensing light on the front of one group of heating components can achieve directional high-strength heating. And there is a driving component that can adjust the corresponding position of the directional component inside the support frame, so as to conveniently achieve directional heating of the corresponding positions of different models of PET plastic bottles.

[0023] For the case of high-shoulder bottle types and too thin distribution of materials at the bottle shoulders, most of such cases are due to the low matching degree between the preform type and the bottle type. The preform structure causes the distribution of materials at the bottle shoulders to be too thin when blowing the empty bottle, and it is difficult to make the distribution of materials at the bottle shoulders meet the requirements of empty bottle top pressure. Most of such preforms are caused by uneven heating of the upper and lower ends of the transition section of the preform body. At this time, we can add a light condensing strip 9 to a specific position of the preform for directional heating according to the bottle type and the preform type, so that the preform is evenly heated to meet the bottle type requirements, and it is convenient to meet the actual production of different models of PET plastic bottles.

[0024] In one embodiment, specifically, the support frame includes a rectangular frame 2 connected to the heating component. Support vertical plates 3 are integrally formed on both sides of the rectangular frame 2, which can provide corresponding support for the directional frame heating component. Sliding grooves 1 for the positioning component to slide are provided inside the two groups of support vertical plates 3, and a plurality of mounting holes 4 for positioning it are provided inside the rectangular frame 2, which is convenient for the fixed installation of the support frame.

[0025] Specifically, the heating component includes two connecting ends 5 detachably installed at the bottom of the rectangular frame 2. A heating lamp tube 6 is installed between the two connecting ends 5. A cable 7 is connected to the side of the connecting end 5 away from the heating lamp tube 6. Turning on the heating lamp tube 6 can heat the material, and the connecting end 5 and the rectangular frame 2 can be detachably connected by bolts or the like, which is convenient for the repair and replacement of the damaged heating lamp tube 6.

[0026] On the basis of the above embodiment, specifically, the directional component includes two connecting rods 8 slidably installed inside the sliding groove 1. A condenser strip 9 located directly in front of one of the heating lamp tubes 6 is installed between the two connecting rods 8. One end of one of the connecting rods 8 away from the condenser strip 9 is connected to the driving component. Walking components for controlling the condenser strip 9 to roll above the rectangular frame 2 are installed on both of the two connecting rods 8. The condenser strip 9 is made of a convex glass strip, which can focus the heating of the heating lamp tube 6 at a fixed position. The number of directional components, driving components, etc. required for actual production can be installed on the support frame.

[0027] Among them, the walking component includes a gear 10 fixedly installed on the connecting rod 8, and a rack 11 meshing with the gear 10 is provided on the rectangular frame 2. Specifically, the driving component includes a servo motor 13 fixedly connected to the end of one of the connecting rods 8. A moving bracket 14 is slidably installed on the support vertical plate 3 close to the servo motor 13. The bottom of the moving bracket 14 is fixedly connected to the servo motor 13, and a communicating groove 15 for the moving bracket 14 to slide is provided inside the support vertical plate 3.

[0028] Start the servo motor 13. The servo motor 13 drives the connecting rod 8 connected to its output end to rotate. The connecting rod 8 drives the gear 10 and the condenser strip 9 to rotate. The gear 10 rotates on the top of the rack 11, which can make it move up and down while rotating. The gear 10 drives the connecting rod 8 and the servo motor 13 to move. The servo motor 13 can drive the moving bracket 14 to slide inside the communicating groove 15. The connecting rod 8 drives the condenser strip 9 to rotate. The distance between adjacent heating lamp tubes 6 can be equal to the circumference of the condenser strip 9, which is convenient for adjusting the condenser strip 9 to directly in front of different heating lamp tubes 6.

[0029] Further, a roller 12 is rotatably mounted on the surface of the connecting rod 8 located inside the sliding groove 1. The surface of the roller 12 is in contact with the inner wall of the sliding groove 1. The connecting rod 8 drives the roller 12 to roll inside the sliding groove 1, which can improve the stability of the overall movement of the positioning component and the driving component.
