Description

Technical Field

[0001] The utility model relates to the technical field of bottle blowing machines, in particular to a preform heating mechanism for a variable pitch bottle blowing machine. Background Art

[0002] The bottle blowing machine is a machine that can blow plastic particles (softened into liquid) or finished bottle embryos into bottles through certain process means. The bottle blowing machine is convenient and fast, with a large molding volume. After its appearance, it replaced most manual bottle blowing and was adopted by most beverage companies.

[0003] In the bottle blowing machine, there is a heating part, which preheats the preform to prepare for the subsequent blow molding. The current heating device usually uses a heating tube for heating. Multiple heating tubes are fixed on the side of the equipment. For the fixing of the heating tube, such as Figure 1-4 As shown, the lamp tube is now clamped by a clip, and the clip is connected to a support rod. The lamp tube is clamped and fixed by the clip, and then the support rod is fixed. When the support rod is fixed, the support rod passes through the support block through a sliding support block, and the support block is fixed with a fastening screw, and the support rod is also fixed to the support block with a fastening screw. This method has the following shortcomings. First, the lamp tube is a heat-generating element, and the clip is a plastic part. As the use time increases, it will deform, and there is a risk of unstable clamping of the lamp tube; second, the fixing of the support rod is relatively troublesome, and it will increase the volume of the overall equipment, and the control operation end of the support rod is located in a visible and operable space, and there is a risk of misoperation; third, the relative vertical position between the two lamp tubes is far, and there is a certain restriction in spatial position.

The components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0034] Therefore, the following detailed description of the embodiments of the utility model provided in the accompanying drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents selected embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0035] Please refer to Figure 5-14 , a preform heating mechanism for a variable pitch bottle blowing machine, comprising a heating box 1, wherein a plurality of heating lamps 2 are installed in the heating box 1;

[0036] The heating box 1 is provided with locking parts 3 on the left and right sides, and the locking parts 3 are structures for fixing the heating lamp tube 2.

[0037] In this device, the heating box 1 has an open structure on one side close to the bottle blowing machine, and the heating lamp 2 is installed in the heating box 1. The bottle blank is preheated by the heating lamp 2. The specific structure of the heating box 1 and the heating lamp 2 is not improved.

[0038] The locking part 3 is located on the side of the heating box 1 close to the bottle blowing machine. At this time, only a part of the entire locking part 3 is located on the outside of the heating box 1, which can reduce the volume of the heating mechanism as a whole. At this time, most of the locking part 3 is located inside the heating box 1, and other people cannot easily operate the locking part 3. The locking part 3 is in a stable state and there is no safety hazard. Finally, the lamp tube is fixed by the locking part 3. At this time, the clamp for clamping the lamp tube is no longer needed, and the locking part 3 will not be deformed, thereby eliminating the safety hazard.

[0039] The locking portion 3 includes a first clamping block 4 connected to the heating box 1 . The first clamping block 4 is provided with a plurality of first clamping grooves 5 along the vertical direction. The heating lamp 2 is clamped into the first clamping grooves 5 .

[0040] There are square blocks on both sides of the heating lamp tube 2, and the square blocks are clamped in the first clamping groove 5, thereby limiting the displacement of the heating lamp tube 2 in the vertical direction.

[0041] The first clamping block 4 is detachably connected to the heating box 1 .

[0042] A supporting foot 6 is fixed to the lower end of the first clamping block 4 , a through hole is provided on the supporting frame, and a locking screw passes through the through hole and is threadedly connected to the heating box 1 .

[0043] The first clamping block 4 is a sheet metal part, and the first clamping block 4 is connected to the heating box 1 by locking screws, which is convenient when replacing the heating lamp tube 2 later.

[0044] The locking portion 3 also includes a second clamping block 7 connected to the heating box 1 , and a plurality of second clamping grooves 8 are provided on the second clamping block 7 along the vertical direction. The heating lamp 2 is inserted into the second clamping groove 8 , and the height of the second clamping groove 8 is less than the height of the first clamping groove 5 .

[0045] The height of the second slot 8 is smaller than that of the first slot 5, the inner side of the square block fits with the second block 7, and the height of the second slot 8 is slightly larger than the outer diameter of the heating lamp tube 2, so that the normal passage of the heating lamp tube 2 can be ensured, and the heating lamp tube 2 can be limited, thereby limiting the position of the heating lamp tube 2 in the horizontal direction.

[0046] The second clamping block 7 is located inside the first clamping block 4 .

[0047] A spacer sleeve 9 is fixed inside the first clamping block 4 , and a fastening screw is threadedly connected with the spacer sleeve 9 to tightly press the second clamping block 7 to form a structure for fixing the second clamping block 7 .

[0048] The second clamping block 7 is also a sheet metal part, and the first clamping block 4 is fixed by the cooperation of the fastening screws and the spacer 9 .

[0049] Other methods may also be used to fix the second clamping block 7 , such as a fixing method similar to that of the first clamping block 4 .

[0050] The locking portion 3 also includes a third clamping block 10 connected to the heating box 1. The third clamping block 10 is located outside the heating box 1. The third clamping block 10 is an L-shaped structure. The longitudinal portion of the third clamping block 10 is a structure for limiting the movement of the heating lamp 2 toward the front side.

[0051] The third clamping block 10 is an L-shaped structure, with the transverse portion located on the outside of the heating box 1 and the longitudinal portion located on the front side of the heating box 1. The longitudinal portion is fitted with the square block, and the rear side of the square block is in contact with the first clamping groove 5. In this way, the first clamping block 4 cooperates with the third clamping block 10 to limit the front and rear positions of the heating lamp tube 2. Similarly, the third clamping block 10 also adopts sheet metal.

[0052] In the present device, the first clamp block 4, the second clamp block 7 and the third clamp block 10 cooperate to limit the heating lamp tube 2 in all directions, thereby locking the heating lamp tube 2. In this way, the locking portion 3 will not be deformed due to the heating of the heating lamp tube 2, and there is no safety hazard.

[0053] The third block 10 is provided with a plurality of heat dissipation openings 11 .

[0054] A plurality of hooks 12 are fixed to the front end of the second clamping block 7 , and a groove is provided on the third clamping block 10 . The hooks 12 are inserted into the groove to form a structure for limiting the position of the third clamping block 10 .

[0055] The hook 12 is inserted into the groove to limit the position of the third block 10 and increase the firmness of the entire device.

[0056] The third clamping block 10 is detachably connected to the heating box 1 via bolts.

[0057] In this device, the first card block 4, the heating box 1 and the third card block 10 cooperate to form a relatively sealed structure at the front end. At this time, a heat dissipation port 11 is opened on the third card block 10, which can allow the heat dissipation wind to dissipate heat to the square block at a fixed point, thereby improving the heat dissipation efficiency.

[0058] When the device is in use, the first clamp block 4 and the second clamp block 7 are first installed, and then the heating lamp 2 is inserted into the first clamp slot 5 and the second clamp slot 8 , and then the third clamp block 10 is installed to complete the fixing of the heating lamp 2 .
