Description

[Technical field]

[0001] The invention relates to the technical field of bottle blowing machines, and in particular to a preform arranging machine. [Background technology]

[0002] Blow Molding Machine refers to a machine that blows bottles. The most common explanation is that it can blow plastic particles (softened into liquid) or finished bottle embryos into bottles through certain process methods. Blow molding machines are convenient and fast, with a large molding volume. After their appearance, they replaced most manual bottle blowing and were adopted by most beverage companies.

[0003] Bottle preform production equipment can produce thousands of bottle preforms per hour, resulting in a large number of bottle preforms being delivered to the entire machine. Figure 8 As shown, the current method of returning the preforms to the whole-line machine equipped with the bottle blowing machine usually adopts the method of returning the preforms by the returning tube 300 or the returning slide. This method has requirements on the height of the returning and recycling points of the whole-line machine. If the height difference is too small, the sliding angle of the bottle preform is not enough, which may cause the bottle preform to be unable to slide down and get stuck on the returning tube or the returning slide, resulting in the phenomenon of preform accumulation, and the returning function cannot be realized.

[0004] In view of this, the inventor of this case conducted in-depth research on the above-mentioned issues, which led to the emergence of this case. [Summary of the invention]

The preform return conveying mechanism 4 adopts a preform return method of a preform return conveying belt 43 to directly reversely convey the preforms that have been successfully aligned to the input end of the single-lane aligning head 2, replacing the original recovery method of the preform return tube and the preform return slideway. The preforms can be effectively prevented from sliding unsmoothly in the preform return tube due to insufficient height difference, and the preforms are stuck or accumulated. At the same time, the overall height of the aligning machine is effectively reduced, and the machine is more suitable for places with height restrictions on factories, and has a wider range of applications and higher economic benefits.

A plurality of partition plates 45 are arranged at equal intervals on the surface of the embryo return conveying belt 43. The unaligned preforms fall on the embryo return conveying belt 43. The arrangement of the partition plates 45 can prevent the preforms from sliding and ensure that the preforms are stably conveyed upward.

[0041] Preferably, the preform return conveying mechanism 4 further comprises a conveying cover 46 mounted on the conveying frame 41 and covering the preform return conveying belt 43. The conveying cover 46 can prevent the preforms from falling and also has a dust-proof function.

The preforms fall into the alignment assembly 21, and the first preform-feeding roller assembly 22 and the second preform-feeding roller assembly 23 rotate continuously to make the disordered preforms fall into the preform gap 26. Since the single-lane alignment head 2 is arranged from high to low from the input end to the output end, the preforms can be slowly aligned and transported forward.

The preform gap 26 is larger than the outer diameter of the bottle body 201 and smaller than the outer diameter of the support ring 202, so as to ensure that the support ring 202 abuts against the roller and the bottle body 201 is stuck in the preform gap 26. Preferably, the outer diameter of the bottle mouth 203 is larger than the preform gap 26, so that each preform 200 has the bottle mouth 203 facing upward, the orientation of the preforms 200 is more uniform, and the arrangement is more neat.

By moving the height of the mounting plate 2541 up and down, the idler set 2543 can adjust the tension of the chain. The idler assembly 254 cooperates with the spacing adjustment assembly 27 to adjust the gap 26; when the gap 26 needs to be increased, the idler assembly 254 moves downward to reduce the chain tension; when the gap 26 needs to be reduced, the idler assembly 254 moves upward to increase the chain tension.

[0055] In the present invention, as shown in the attached Figure 1As shown, the frame 1 includes an upper frame assembly 11 and a lower frame assembly 12 that are interlocked; the lower frame assembly 12 is equipped with a staircase assembly 13. The upper frame assembly 11 and the lower frame assembly 12 have corresponding matching holes. The upper frame assembly 11 and the lower frame 1 are fixed together with screws, and then the single-track aligning head 2 is fixed to the upper frame assembly 11 through the corresponding holes, and then the embryo return conveying mechanism 4 is fixed to the upper frame assembly 11, and finally the embryo return bucket 3 and the aligning machine cover 29 are installed on the single-track aligning head 2. The upper frame assembly 11 and the lower frame assembly 12 play the role of supporting and fixing the single-track aligning head 2 and the embryo return conveying mechanism 4. At the same time, the lower frame assembly 12 is equipped with a staircase assembly 13, which is convenient for personnel to check and maintain the aligning machine.

[0056] Working principle: the preforms are sent into the hopper 28 and enter the temporary preform storage area surrounded by the first side plate 211, the first inclined baffle 213, the second inclined baffle 214 and the second side plate 212. The first preform-entering roller assembly 22 and the second preform-entering roller assembly 23 rotate continuously to make the disordered preforms fall into the preform gap 26 and be aligned. The unaligned preforms are transported forward and pass through the straight preform block assembly 215, the first inclined preform block assembly 216 and the second inclined preform block assembly 217 in sequence, and finally fall into the preform return hopper 3. The preform return hopper 3 transports the preforms to the preform return conveying mechanism 4, and the preform return conveying mechanism 4 then sends the preforms back to the hopper 28.
