Description

Technical Field

[0001] The invention relates to the technical field of plastic bottle blank production equipment, in particular to a cooling and conveying device for plastic bottle blank production. Background Art

[0002] Plastic bottle preforms are semi-finished products specially used for subsequent blow molding to form plastic bottles. They generally have a tubular structure with a relatively large opening at one end and a relatively small opening at the other end. In addition, the plastic bottle preforms also have a certain thickness, which lays a good foundation for the subsequent blow molding process.

[0003] Referring to the Chinese patent, the patent name is: A device for accelerating cooling to assist in the production of plastic bottle blanks (patent publication number: CN112848226B), comprising a conveyor belt, a first baffle, a second baffle and a base arranged on the conveyor belt, an axial flow fan is arranged on one side of the second baffle, a heat exchanger is arranged at the input end of the axial flow fan, a mounting column is arranged in the middle of the base, a mounting groove for the bottle mouth to be clamped is arranged at the top of the base, a receiving groove is arranged on one side of the base, the conveyor belt is installed on the bracket, a guide groove is arranged at the top of the bracket, a guide plate is arranged obliquely at the notch of the receiving groove, and one end of the guide plate is located at the top of the guide groove. The first baffle and the second baffle of the present invention work together to form a relatively sealed space at the bottle mouth, which can block the hot air near the bottle body on the one hand, and reduce the cold air near the bottle mouth from entering the vicinity of the bottle body on the other hand, thereby achieving a heat insulation effect.

[0004] Compared with the patent publication number (CN112848226B), although a relatively sealed space can be formed at the bottle mouth to achieve a heat insulation effect, the following problems still exist:

[0005] 1. Compared with the second through hole in the patent, which is the air outlet of the axial flow fan, it covers the entire conveyor line, but in fact only the bottle mouth part needs cold air cooling, which will cause a large amount of cold air to be wasted in the area that does not need cooling, increasing energy consumption;

[0006] 2. In the comparative patent, the first baffle and the second baffle are arranged on the left and right sides of the conveyor line to block the hot air near the bottle body to achieve the heat insulation effect. However, the front and rear directions of the bottle mouth are still exposed to the external environment, making it difficult to effectively insulate;

[0007] 3. In contrast, when the preforms in the patent are being transported, the direction of the preforms on the mounting column is fixed, which results in local differences when the preforms are heated or cooled, thus affecting the stability and consistency of product quality.

[0008] To this end, the present invention provides a cooling and conveying device for producing plastic bottle blanks. Summary of the invention

[0042] The cooling mechanism 4 includes an adaptive component 42, and the adaptive component 42 includes a connecting plate 421 and a fixed plate 426. The bottom of the connecting plate 421 is fixedly connected with a plurality of connecting columns 422 at equal intervals.

The right surface of the fixed plate 426 is provided with a There is a guide groove 427 for guiding the sliding column 425. When the fixed plate 426 moves, the corresponding sliding column 425 will rise and fall along the trajectory of the guide groove 427 with an arched structure, so that the corresponding adaptive rectangular column 424 forms an arched channel. At this time, through the rectangular groove 413 and the arched channel on the adaptive rectangular column 424 and the air inlet pipe 3211, the air collecting hood 411 is connected with the internal space of the hollow cylinder 323. Cold air enters the interior of the hollow cylinder 323 through the arched channel to cool the bottle mouth of the bottle body 6. Moreover, each air inlet pipe 3211 corresponds to only one arched channel, thereby avoiding the waste of cold air in areas that do not require cooling and reducing energy consumption.

The driving mechanism 2 also includes a motor 21 fixedly mounted on the surface of the side panel 1 for driving the rotating shaft 22 to rotate.

[0044] See also Figure 3-6The bottom end of the thrust ball bearing 313 is fixedly connected with a bottom plate 312, the bottom surface of the bottom plate 312 contacts the top surface of the support frame 11, and the bottom surface of the bottom plate 312 is fixedly connected with a connecting seat 311 near the middle position. The connecting seat 311 is arranged in the gap between the two support frames 11, and the connecting seat 311 is fixedly connected to the chain 24 through a pin shaft. A silicone sleeve 316 is arranged on the top of the column bottle seat 314, and the silicone sleeve 316 is interference fit with the inner wall of the bottle mouth of the bottle body 6, which can make the inner wall of the bottle mouth of the bottle body 6 more firmly connected with the column bottle seat 314.

The tops of the two C-shaped sealing plates 329 are symmetrically fixedly connected with the slide plates 326. The outer wall of the hollow cylinder 323 is symmetrically fixedly connected with the fixing block 324. The two sides of the fixing block 324 are symmetrically fixedly connected with the guide rods 325. The outer wall movably penetrates the surface of the slide plate 326 and extends to the other side. The end of the guide rod 325 is fixedly connected to a limiting cap 327 for limiting the slide plate 326.

The two ends of the spring 328 are fixedly connected to the fixed block 324 and the opposite side surface of the slide plate 326. When the moving mechanism 3 equipped with the bottle body 6 moves to the other side of the line body, at this time, the C-shaped sealing plate 329 will gradually move from the inclined surface on the other side of the guide bar 51 During the disengagement process, under the action of the thrust of the spring 328, the two C-shaped sealing plates 329 move in the opposite direction, thereby opening the C-shaped sealing plates 329, making it easier for the operator or the robot to take away the bottle body 6. The outer wall of the hollow cylinder 323 is fixedly connected to an air outlet duct 3210 near the left side. The air outlet duct 3210 is provided to facilitate the discharge of heat inside the hollow cylinder 323, so that the bottle mouth of the bottle body 6 can be cooled.

[0045] See also Figure 6-9The number of the fixing plates 426 is set to be multiple, and the fixing plates 426 are connected to the end of the air inlet pipe 3211. The right surface of the fixing plate 426 fits with the left surface of the adaptive rectangular column 424. Through the arrangement and cooperation of the adaptive rectangular columns 424, a closed wall is formed, which can separate the inner cavity of the air collecting hood 411 from the air inlet pipe 3211. At the same time, the adaptive rectangular columns 424 are guided by the guide grooves 427 on the fixing plates 426 to form an arched channel. The cold air inside the air collecting hood 411 can only enter the air inlet pipe 3211 from the arched channel, thereby avoiding the waste of cold air in areas that do not require cooling and reducing energy consumption. The cooling mechanism 4 also includes a connecting component 41 and a refrigeration component 43. The connecting component 41 includes an air collecting hood 411. The interior of the air collecting hood 411 is arranged in a cavity. A contact plate 412 is fixedly connected to the left surface of the air collecting hood 411. A rectangular groove 413 is opened through the surface of the contact plate 412. The left surface of the contact plate 412 contacts the right surface of the adaptive rectangular column 424. A support plate 414 is fixedly connected to the bottom of the contact plate 412. The top surface of the support plate 414 contacts the bottom surface of the adaptive rectangular column 424. A plurality of first brackets 415 are fixedly installed at equal intervals on the bottom of the contact plate 412. The first bracket 415 is fixedly installed on the right support frame 11, a plurality of second brackets 5 are fixedly installed on the top of the two side panels 1, and the inner top surface of the second bracket 5 is fixedly connected to the top surface of the connecting plate 421, and a guide strip 51 for limiting the C-shaped sealing plate 329 is fixedly installed between the outer surfaces of the plurality of second brackets 5. The refrigeration assembly 43 includes a compression refrigerator 431. The compression refrigerator 431 is a prior art. The low-temperature and low-pressure refrigerant gas is compressed into a high-temperature and high-pressure gas, which is liquefied in the condenser, depressurized and cooled by a throttling device, and then evaporated in the evaporator by absorbing heat, and then sucked into the compressor. In this way, the cycle is realized to blow cold air for cooling. The output port of the compression refrigerator 431 is set An axial flow fan 432 is provided, through which the cold air generated by the compression refrigerator 431 can be guided into the wind collecting hood 411, the output port of the axial flow fan 432 is fixedly connected with a plurality of connecting pipes 433, through which the cold air can evenly enter the wind collecting hood 411, the end of the connecting pipe 433 is fixedly connected with the right surface of the wind collecting hood 411, a plurality of third brackets 7 are equidistantly fixedly installed on the opposite side surfaces of the guide strip 51, a heating rod 71 is fixedly installed on the top of the third bracket 7, the bottle body of the bottle blank 6 is heated by the heating rod 71, so as to facilitate the subsequent blow molding of the bottle blank 6 into a plastic bottle.

[0046] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0047] During operation, for the produced bottle body 6, the operator or the robot inserts the bottle body 6 on the cylindrical bottle seat 314, and at the same time, the end of the bottle mouth of the bottle body 6 contacts the fixed ring 322, and the bottle mouth of the bottle body 6 is located on the inner side of the hollow cylinder 323. After that, the chain 24 is driven to rotate by starting the motor 21, so as to transport the bottle body 6 on the cylindrical bottle seat 314. During the transportation process, the moving mechanism 3 moves along the direction of the line body, and the C-shaped sealing plates 329 on both sides of the moving mechanism 3 will contact the guide strips 51 on both sides during the movement. When the C-shaped sealing plates 329 begin to contact the inclined surface of the guide strip 51, since the inclined surfaces of the two guide strips 51 are gradually gathered inward, the two C-shaped sealing plates 32 9 is restrained by the guide bar 51 and gathers inward until the C-shaped sealing plate 329 completely enters the plane of the guide bar 51. At this time, the C-shaped sealing plates 329 on both sides are merged, and the inner matching parts of the two C-shaped sealing plates 329 form an inner circle, which just wraps the bottle mouth of the bottle body 6 and slightly contacts with the bottle body 6, but does not generate a clamping force or a fixing force on the bottle body 6. As a result, under the joint action of the fixed ring 322, the hollow cylinder 323 and the two C-shaped sealing plates 329, the bottle mouth of the bottle body 6 is completely in a closed space without dead corners, avoiding the bottle mouth from being exposed to the external environment, thereby improving the heat insulation effect. When the moving mechanism 3 equipped with the bottle body 6 moves to the other side of the line body, at this time, the C-shaped sealing plate 329 will move from the guide bar 51 to the other side of the line body. The inclined surface on the other side of the strip 51 gradually disengages. During the disengagement process, under the action of the thrust of the spring 328, the two C-shaped sealing plates 329 move in the opposite direction, thereby opening the C-shaped sealing plates 329, making it easier for the operator or the manipulator to take away the bottle body 6. When the moving mechanism 3 is moving, the gear 315 will mesh with the rack 81. When the two are meshed, under the joint action of the thrust ball bearing 313 and the cylindrical bottle seat 314, the gear 315 rotates, thereby achieving the effect of self-rotation of the bottle body 6 during the movement, so that the bottle body of the bottle body 6 can be evenly heated, and at the same time, the bottle mouth can also be evenly cooled, thereby solving the problem of local differences when the bottle body is heated or cooled. The bottle body of the bottle body 6 is heated by the heating rod 71. Heat is used to facilitate the subsequent blow molding of the bottle blank 6 into a plastic bottle. When the moving mechanism 3 is moving, the guide groove 427 on the fixed plate 426 will cooperate with the sliding column 425 on the adaptive rectangular column 424. When the fixed plate 426 is moving, the corresponding sliding column 425 will rise and fall along the trajectory of the guide groove 427. Since the trajectory of the guide groove 427 is arched, the corresponding adaptive rectangular column 424 is also arched. At this time, the rectangular groove 413, the arched channel on the adaptive rectangular column 424 and the air inlet pipe 3211 are used to connect the air collecting hood 411 with the internal space of the hollow cylinder 323, and the arched channel of the adaptive rectangular column 424 follows the movement of the fixed plate 426 and changes its position accordingly.In the area outside the arched channel of the adaptive rectangular column 424, a closed wall is formed by the joint action of the adaptive rectangular column 424 at a low position, and the closed wall is in contact with the contact plate 412, so that the cold air inside the air collecting hood 411 can only be discharged from the arched channel to the hollow cylinder 323. When the compression refrigerator 431 is running, the axial flow fan 432 cooperates to transport the cold air to the inside of the air collecting hood 411 through the connecting pipe 433. At this time, the cold air enters the air inlet pipe 3211 through the arched channel, and then enters the inside of the hollow cylinder 323 to cool the bottle mouth of the bottle body 6. In addition, each air inlet pipe 3211 corresponds to only one arched channel, thereby avoiding the waste of cold air in areas that do not need to be cooled, reducing energy consumption, and finally, the hot air is discharged through the air outlet pipe 3210.
