Description

Technical Field

[0001] The invention relates to the technical field of bottle blowing machines, and in particular to a full-automatic linear plastic bottle blowing machine. Background Art

[0002] A plastic bottle blowing machine is a device that uses a blow molding process to make plastic particles into hollow containers. Among them, the more common models are fully automatic linear plastic bottle blowing machines, which are generally composed of transmission equipment, extrusion equipment, molding molds and bottle blowing equipment. Its working principle is to mix, melt and extrude the plastic raw materials into the molding mold through the extrusion equipment, and then use the wind blown out by the bottle blowing equipment to blow the plastic body to fit the inner wall of the mold, and then cool and shape it. Finally, after the mold is opened, the plastic bottle is transported to the subsequent processing position through the transmission equipment.

[0003] The advantages of this solution are large molding volume and high production efficiency, which is very conducive to mass production. However, there is also a problem that the remaining mixed raw materials in the extrusion equipment after production are completed are difficult to screen, resulting in a waste of raw materials that needs to be solved.

[0004] There is another scheme in the prior art, such as a blow molding machine for plastic bottle production with Chinese patent publication number CN117719119B, which includes a blow molding machine body, an extrusion device is arranged on the top of the blow molding machine body, and also includes a closed cylinder, a discharge hopper, a flip drive assembly, a screen plate and a feeding assembly. The closed cylinder is located on the upper side of the extrusion device, the discharge hopper is connected to the bottom of the closed cylinder, a flip drive assembly is arranged between the closed cylinder and the blow molding machine body, and the flip drive assembly is used to drive the closed cylinder to move, the number of screen plates is set to multiple, and the multiple screen plates are fixedly connected in the closed cylinder, the number of feeding assemblies is set to multiple, and the multiple feeding assemblies are rotatably arranged on the closed cylinder.

[0005] This solution uses screening plates with different apertures to screen plastic raw materials of different particle sizes after production is completed, thereby achieving the purpose of raw material recovery and reducing waste. However, the following problems still exist. First, during the mixing and feeding stage, although the screening plate structure is a sunken type in the middle, which can guide the raw materials to fall in a concentrated manner, due to the presence of sieve holes of different diameters, some small-volume raw materials will still fall regularly through the smaller sieve holes on the screening plate, which is not conducive to the uniformity of the mixing. Second, during the screening and recovery stage, different plastic raw material particles have similar volumes, which results in a limited screening effect by screening by aperture size, which needs to be further improved.

[0035] like Figures 1 to 12 As shown: A fully automatic linear plastic bottle blowing machine includes a base 1 and a blow molding assembly 10. The blow molding assembly 10 is installed on the base 1. The blow molding assembly 10 is used to melt plastic raw materials and blow mold them into plastic bottles. The blow molding assembly 10 includes a melting device, a blow molding device and a mold. The plastic is expected to be put into the mixing barrel 2 through the feed port. After sufficient mixing, it is discharged from the discharge port and falls into the feed port of the blow molding assembly 10. Then, it is heated to a molten state by the melting device, and blow molded in the mold by the blow molding device. Finally, after the plastic bottle is cooled, the mold is opened to complete the blow molding process. It also includes a mixing barrel 2, a frame 20, a partition 21, a sieve plate 22, a flip assembly 3, a mixing assembly 4 and a screening assembly 5. The mixing barrel 2 is flipably installed on the base 1 through the flip assembly 3. The discharge port of the mixing barrel 2 is connected to the feed port of the blow molding assembly 10. The feed port of the mixing barrel 2 is located at the top, and the discharge port of the mixing barrel 2 is located at the bottom. The skeleton 20 can be installed on the mixing barrel 2 in a vertically slidable manner, and the partition 21 and the sieve plate 22 can be installed on the skeleton 20 in a horizontally rotatable manner. A through groove 210 is provided on the top of the partition 21, and a through empty groove 220, a first sieve hole 221 and a second sieve hole 222 are provided on the top of the sieve plate 22. The empty groove 220, the first sieve hole 221 and the second sieve hole 222 are arranged in a circle on the sieve plate 22. The diameter of the first sieve hole 221 is smaller than the diameter of the second sieve hole 222. When mixing, the relative position between the sieve plate 22 and the partition 21 is changed by rotating the sieve plate 22, so that the open holes on the sieve plate 22 can be selectively adjusted. The mixing component 4 is installed on the mixing barrel 2, and the mixing component 4 is used to drive the sieve plate 22 to rotate. The screening component 5 is installed on the base 1, and the screening component 5 is used to drive the skeleton 20 to slide up and down quickly. When the empty slots 220, the first sieve holes 221 and the second sieve holes 222 on the sieve plate 22 are all in a closed state, the rotating sieve plate 22 can stir and mix the raw materials, and the sieve plate 22 rotates clockwise to this state. At this time, the raw materials in the mixing barrel 2 fall to the top of the partition 21, and then the sieve plate 22 continues to rotate clockwise while driving the partition 21 to rotate at the bottom of the skeleton 20, which can drive the raw materials on the top of the partition 21 to rotate, and stir the raw materials. After stirring evenly, the sieve plate 22 rotates in the opposite direction. When the through groove 210 and the empty groove 220 are connected, the rotating sieve plate 22 can transport the raw materials to the bottom of the mixing barrel 2. When the sieve plate 22 rotates counterclockwise to this state, the sieve plate 22 continues to rotate counterclockwise and drives the partition 21 to rotate at the bottom of the skeleton 20, so that the evenly mixed raw materials can be scraped from the empty groove 220 to the discharge port for discharge, completing the mixing. The empty groove 220 is relatively large in size, so all raw material particles of different sizes can pass through smoothly, avoiding the occurrence of unevenness when falling.When the through slot 210 is connected to the first sieve hole 221, the mixing barrel 2 can be turned over to screen the raw materials with smaller particle diameters. After the blow molding process is completed, the sieve plate 22 is rotated to this state, and the mixing barrel 2 is turned over 180 degrees by the turning component 3. At this time, the remaining raw materials in the mixing barrel 2 are located on the top of the sieve plate 22. Then, the skeleton 20 and the sieve plate 22 are driven to shake up and down by the screening component 5, so that the smaller particles in the remaining raw materials are quickly screened out through the first sieve hole 221, so that they fall to the bottom of the partition 21, and these raw materials are discharged and recovered from the feed port of the mixing barrel 2, and the above operation is repeated. When the through slot 210 and the second sieve hole 222 are connected, the mixing barrel 2 can be turned over to screen the raw materials with larger particle diameters. Similarly, the remaining raw materials with larger diameters are screened out and recovered through the second sieve hole 222, which can avoid the waste of the remaining raw materials and has a high screening efficiency.

[0036] like Figures 1 to 10 As shown: The skeleton 20 includes a shell 200, a pair of scrapers 201, a fixing ring 202, a pair of connecting blocks 203 and a sealing plate 204. The fixing ring 202 is sleeved on the outer periphery of the shell 200, and the scrapers 201 are symmetrically distributed at both ends of the shell 200. One end of the scraper 201 is fixedly connected to the outer periphery of the shell 200, and the other end of the scraper 201 is fixedly connected to the inner wall of the fixing ring 202. Through the setting of the scraper 201, when mixing, the relative rotation between the scraper 201 and the partition 21 can stir the raw materials and improve the uniformity of the mixing. After the mixing is completed, the raw materials can be quickly scraped into the empty groove 220 to improve the mixing efficiency. The partition 21 is rotatably connected to the outer periphery of the housing 200, the sieve plate 22 is rotatably connected to the bottom of the housing 200, the top of the sieve plate 22 is fitted to the bottom of the partition 21, the top of the partition 21 is fitted to the bottom of the scraper 201, the outer periphery of the partition 21 and the outer periphery of the sieve plate 22 are both fitted to the inner wall of the mixing barrel 2, the mixing barrel 2 can be divided into two parts, the upper and lower parts, and the sieve plate 22 and the partition 21 can be horizontally rotated inside the mixing barrel 2. One end of the connecting block 203 is fixedly connected to the outer periphery of the fixing ring 202, the sealing plate 204 is sleeved on the outer periphery of the mixing barrel 2 and slidably connected thereto, and the other end of the connecting block 203 passes through the side wall of the mixing barrel 2 and is fixedly connected to the sealing ring. Through the setting of the annular sealing plate 204, the connecting block 203 is fixedly connected to the skeleton 20, and the skeleton 20 can be moved up and down along the mixing barrel 2 while preventing the raw materials from spilling out of the mixing barrel 2.

[0037] like Figures 1 to 10 As shown: The mixing assembly 4 includes a first motor 40 and a limit block 41. The bottom of the first motor 40 is fixedly connected to the bottom wall of the shell 200. The output shaft of the first motor 40 passes through the bottom wall of the shell 200 and is fixedly connected to the top of the sieve plate 22. The bottom of the limit block 41 is fixedly connected to the top of the sieve plate 22. An arc groove 211 is provided at the bottom of the partition 21. The arc groove 211 is slidably connected to the limit block 41. When the first motor 40 is powered on, its output shaft can drive the sieve plate 22 to rotate horizontally at the bottom of the skeleton 20. The limit block 41 rotates synchronously with the sieve plate 22 and slides along the arc groove 211. When the stopper 41 is located at one end of the arc groove 211, the empty groove 220 is in a sealed state. At this time, as the sieve plate 22 continues to rotate, the stopper 41 and the inner wall of the arc groove 211 conflict with each other, thereby driving the partition 21 and the sieve plate 22 to rotate together. Since the skeleton 20 is fixed, the partition 21 and the scraper 201 rotate relative to each other, and the raw materials are stirred by the cooperation between the scraper 201 and the partition 21. When the stopper 41 is located at the other end of the arc groove 211, the empty groove 220 is connected to the through groove 210. At this time, as the sieve plate 22 continues to rotate, the partition 21 rotates in the opposite direction with the sieve plate 22, and cooperates with the scraper 201 to scrape off the raw materials on its top to complete the mixing.

[0038] like Figures 1 to 12 As shown: The turning assembly 3 includes a frame 30, a rotating seat 31, a rotating shaft 32, a support plate 33, a second motor 34 and a rotating sleeve 35. The rotating sleeve 35 is fixedly connected to the periphery of one end of the mixing barrel 2, the bottom of the frame 30 is fixedly connected to the top of the base 1, the bottom of the rotating seat 31 is fixedly connected to the top of the frame 30, the rotating shaft 32 passes through the rotating seat 31 and is rotatably connected thereto, the support plate 33 is horizontally movably installed on the frame 30, one side of the motor is fixedly connected to the support plate 33, the output shaft of the motor passes through the support plate 33 and is coaxially connected to one side of the rotating shaft 32, the rotating sleeve 35 is sleeved on the periphery of the rotating shaft 32, and the rotating sleeve 35 is rotatably connected to the inner wall of the rotating seat 31, so that the second motor 34 is energized to work, and its output shaft drives the rotating shaft 32 to rotate in the rotating seat 31, and cooperates with the hydraulic rod 38 to adjust the position of the rotating shaft 32, which can respectively drive the mixing barrel 2 to flip and the sieve plate 22 to shake up and down. The bottom of the rotating sleeve 35 and the bottom wall of the rotating seat 31 are in contact with each other to prevent the rotating sleeve 35 from excessively rotating toward the bottom when the block 36 is separated from the square groove 350. The mixing assembly 4 also includes a pair of valves 42, and the two valves 42 are respectively installed in the feed port and the discharge port of the mixing barrel 2. The setting of the valves 42 can close the feed port and the discharge port of the mixing barrel 2 when the mixing barrel 2 is turned over to prevent the raw materials from spilling out.

[0039] like Figures 1 to 12 As shown: The screening assembly 5 includes a support rod 50, a pair of pull rings 51, two pairs of tension springs 52, and a pair of pressing mechanisms 53. One side of the support rod 50 is fixedly connected to one side of the sealing plate 204, one end of the tension spring 52 is fixedly connected to one end of the sealing plate 204, the two pairs of tension springs 52 are symmetrically distributed at the top and bottom of the two pull rings 51, one end of the tension spring 52 is fixedly connected to the tension spring 52, and the other end of the tension spring 52 is fixedly connected to the mixing barrel 2. The pressing mechanism 53 is installed on the frame 30, and the pressing mechanism 53 is used to press the support rod 50 downward to drive the skeleton 20 to move up and down. After the blow molding is completed, the mixing barrel 2 is turned over, and the remaining raw materials inside it are turned over to the top of the sieve plate 22. Then, one of the pressing mechanisms 53 continuously and quickly presses down the support rod 50, driving the frame 20 to slide down, and the tension spring 52 on the top is stretched. Then, the tension spring 52 rebounds and drives the frame 20 and the sieve plate 22 to move up, causing the sieve plate 22 to shake up and down. Through continuous and rapid shaking in conjunction with the first sieve hole 221 and the second sieve hole 222, raw material particles of different sizes are screened out, completing the raw material recovery. After shaking and screening, the particles are similar in size. The raw materials pass through the sieve plate 22 and fall into the bottom of the partition 21, and then the mixing barrel 2 is turned back to its original position. At this time, the screened raw materials fall to the top of the partition 21. At this time, the sieve plate 22 is closed, and another pressing mechanism 53 slowly and long-distance presses the support rod 50, so that the skeleton 20 first slowly slides down and then bounces up quickly, and the raw materials on the top are thrown up, and the fan 54 on the top is used to suck the lighter raw material particles out of the mixing barrel 2, and the heavier raw material particles fall back, so as to further screen the raw materials and improve the screening accuracy.

[0040] like Figures 1 to 12 As shown: The pressing mechanism 53 includes a first gear 530, a pair of second gears 531, a pair of turntables 532 and a pair of round rods 533. The first gear 530 is coaxially connected to the periphery of the rotating shaft 32. The round rod 533 passes through the supporting plate 33 and is coaxially connected thereto. The two second gears 531 are respectively located at both ends of the first gear 530. The second gear 531 is coaxially connected to the periphery of the round rod 533. The second gear 531 meshes with the first gear 530. The turntable 532 is coaxially connected to the periphery of the round rod 533. The periphery of the turntable 532 close to the feed port of the blow molding component 10 is fixedly connected to a first extrusion rod 534. The periphery of the turntable 532 away from the blow molding component 10 is fixedly connected to a plurality of second extrusion rods 535. The plurality of second extrusion rods 535 are circumferentially distributed on the periphery of the turntable 532. The length of the second extrusion rod 535 is less than the first extrusion rod 534. When the rotating shaft 32 rotates, the first gear 530 is driven to rotate, and the round rod 533 and the rotating disk 532 are driven to rotate through the meshing transmission between the first gear 530 and the second gear 531. When the mixing barrel 2 is turned to the end away from the feeding port of the blow molding component 10, the second extrusion rods 535 and the support rods 50 conflict with each other. As the rotating disk 532 rotates, one of the second extrusion rods 535 squeezes the support rod 50 downward. As the rotating disk 532 continues to rotate, the two are separated, and then the support rod 50 quickly rebounds and aligns with the other. The second extrusion rods 535 collide with each other, causing the screen plate 22 to continuously shake up and down, and the first round of screening is performed. Then the mixing barrel 2 is flipped to the end close to the feed port of the blow molding component 10. At this time, the first extrusion rod 534 and the support rod 50 collide with each other. As the turntable 532 rotates, the first extrusion rod 534 squeezes the support rod 50 downward, causing the partition 21 to slide downward, and the sliding distance is relatively long. Then the two separate, and the partition 21 rebounds quickly, throwing the raw materials upward, so that raw materials of different qualities are fully separated, and the second round of screening is performed.

[0041] like Figures 1 to 4 As shown: The screening assembly 5 also includes a fan 54 and a hose 55. The bottom of the fan 54 is fixedly connected to the top of the base 1. The air inlet of the fan 54 is connected to one end of the hose 55. The other end of the hose 55 is detachably connected to the feed port of the mixing barrel 2 through a thread. The top and bottom of the mixing barrel 2 are both conical structures protruding in the middle. It is convenient to concentrate the outflow of raw materials. After the blow molding is completed, the free end of the hose 55 is threadedly connected to the feed port of the mixing barrel 2. In the second round of screening, the fan 54 is operated to quickly extract the air at the top of the mixing barrel 2 through the hose 55 to form a negative pressure space, thereby absorbing some of the lighter particles in the raw materials thrown up by the partition plate 21 for further screening.

[0042] like Figures 1 to 12 As shown: The flip assembly 3 further comprises a block 36, a pair of guide rods 37 and a hydraulic rod 38. The block 36 is fixedly connected to the outer periphery of the rotating shaft 32. A square groove 350 is provided on the inner wall of the rotating sleeve 35. The square groove 350 is engaged with the block 36. The guide rod 37 passes through the rotating seat 31 and is fixedly connected thereto. The support plate 33 is slidably connected to the outer periphery of the guide rod 37. One end of the hydraulic rod 38 is fixedly connected to the inner wall of the rotating seat 31. The telescopic end of the hydraulic rod 38 passes through the side wall of the rotating seat 31 and is fixedly connected to the support plate 33. When the hydraulic rod 38 is operated, the support plate 33 is pushed to move horizontally along the guide rod 37, driving the rotating shaft 32 and the block 36 to slide. When the block 36 is engaged with the square groove 350, the rotating shaft 32 is coaxially connected with the rotating sleeve 35. The rotating shaft 32 can drive the mixing barrel 2 to flip. When the block 36 is separated from the square groove 350, the extrusion rod and the support rod 50 conflict with each other, and the rotating shaft 32 can drive the sieve plate 22 to shake up and down.
