Description

Technical Field

[0001] The present invention relates to the technical field of plastic bottle processing, and specifically to an automatic feeding and pipe supply mechanism and a bottle making machine. Background Art

[0002] A plastic bottle is a plastic container formed by adding organic solvents to materials such as polyethylene or polypropylene, heating at high temperature, and then through blow molding, extrusion blow molding, or injection molding using a plastic mold. It is widely used in liquid or solid disposable plastic packaging containers for videos, beverages, pickles, dried fruits, edible oils, etc.

[0003] In the existing plastic bottle blow molding process, the raw materials need to be heated first and then extruded into the shape of a test tube. Then, after reheating, blow molding and cooling are carried out to form a complete plastic bottle. When transporting the preliminarily formed test tubes, generally, through the support rings on the test tubes, the test tubes are clamped inside the transport clamping tubes. Due to the large production quantity, during the transportation process, some test tubes often cannot enter the clamping tubes due to stacking and are stuck outside the clamping tubes. And along with the transportation of the test tubes inside the clamping tubes, these test tubes fall off from the clamping tubes, which affects the transportation effect of the test tubes. Even if another feeding component is used to collect and clamp the fallen parts again, there will still be problems where some cannot be clamped due to stacking.

[0004] Based on this, the present invention designs an automatic feeding and pipe supply mechanism and a bottle making machine to solve the above problems. Summary of the Invention

A plurality of rotatable forming molds are arranged on the blow molding machine at equal intervals. A corresponding blowing tube is slidably connected to the upper end of the forming mold. A top pushing and dialing mechanism is arranged on the clamping tube. The top pushing and dialing mechanism can dial the tubes that are stacked on the clamping tube and cannot be transported orderly through the clamping tube, and then clamp them orderly inside the clamping tube for transportation.

A connecting belt is rotatably connected to the common bottom end of the two fixing plates. A second motor is fixedly connected to the bottom end of the fixing plate. The output end of the second motor is rotatably connected to the connecting belt. Several connecting rods evenly distributed at equal intervals are slidably arranged on the outer wall of the connecting belt. Two adjacent connecting rods are fixedly connected by a return spring. Both ends of the connecting rod are respectively fixedly connected with a rotating shaft. A first swing rod is rotatably connected to each rotating shaft.

A V-shaped sliding groove capable of slidingly connecting with the sliding rod is fixedly connected to the bottom end of the fixing piece.

[0009] As a further solution of the present invention, a magnetic attraction block is fixedly connected inside the connecting rod, and a metal block capable of being attracted by the magnetic attraction block is embedded at one end of the second swing rod.

[0010] As a further solution of the present invention, the internal heating temperature of the heating channel is about one hundred and fifteen degrees Celsius.

[0011] As a further solution of the present invention, the tube body is composed of a connecting tube, a supporting ring, and a threaded head. The outer walls of the conveying frames are all smooth walls. The gap between the conveying frames is the same as the gap between the material clamping tubes. The width of the gap is greater than the vertical cross-sectional width of the tube body and less than the circumferential diameter of the supporting ring on the tube body.

[0012] As a further solution of the present invention, a water cooling channel is provided inside the forming die. A water cooling inlet is provided at the top end of the forming die, and a water cooling outlet is provided at the bottom end of the forming die.

[0013] As a further solution of the present invention, the outer wall of the top end of the ejector rod is in the shape of a chamfered arc, and the outer walls of the ejector rods are all smooth walls.

[0025] Please refer to Figures 1-7, the present invention provides a technical solution: an automatic loading and pipe supply mechanism and a bottle making machine, including a conveyor 2, a storage cavity 1 is fixedly connected to the lower end of the conveyor 2, a baffle 3 is fixedly connected to one side of the top end of the conveyor 2, a clamping pipe 11 is fixedly connected to the bottom end of the baffle 3, a conveying frame 4 extending obliquely downward is fixedly connected to one end of the clamping pipe 11, a heating channel 5 is sleeved at the other end of the conveying frame 4, a blowing machine 6 is fixedly connected to the output end of the heating channel 5, a plurality of rotatable forming molds 9 are arranged on the blowing machine 6 at equal intervals, a blowing pipe 8 corresponding to the forming mold 9 is slidably connected to the upper end of the forming mold 9, and a top pushing and dialing mechanism is arranged on the clamping pipe 11, and the top pushing and dialing mechanism can push the pipes that are stacked on the clamping pipe 11 and cannot be transported orderly through the clamping pipe 11, and after being dialed, they are orderly stuck inside the clamping pipe 11 for transportation;

[0026] When the above solution is put into actual use, when producing plastic bottles, first mix the raw materials for production and heat them, extrude them into the forming cavity for preliminary forming and then cool them. At this time, the raw materials already have a preliminary test tube-shaped appearance. Transport the cooled tubes into the storage cavity 1, transport the tubes to the inside of the baffle 3 above the clamping pipe 11 through the conveyor 2. The tubes gradually enter the inside of the clamping pipe 11 during transportation through the inclined baffle 3, and are transported in an orderly and unified direction inside the clamping pipe 11. During the transportation of the tubes, the top pushing and dialing mechanism pushes the tubes stuck at the upper end of the clamping pipe 11, and the distance between adjacent tubes inside the clamping pipe 11 is such that the stuck tubes can be smoothly transported into the clamping pipe 11 after being pushed. The test tubes transported through the clamping pipe 11 enter the heating channel 5 along the conveying frame 4. After being heated inside the heating channel 5, the surface hardness of the tubes is reduced. After the tubes with reduced hardness enter the forming mold 9, the forming mold 9 closes, the blowing pipe 8 moves down to dock with the opening of the tube, first pass low-pressure air into the tube and then high-pressure air to make the tube fill the inside of the forming mold 9, and a plastic bottle can be made after cooling. The present invention can push the stuck tubes into the clamping pipe 11 through the top pushing and dialing mechanism, so that there will be no material blocking problem on the clamping pipe 11, and no tube will fall from the conveying frame 4 during transportation.

[0027] As a further solution of the present invention, the top pushing and dialing mechanism includes a first motor 10, the first motor 10 is fixed at one end of the clamping pipe 11, a plurality of swing frames 14 connected in sequence are rotatably arranged inside the clamping pipe 11, the output end of the first motor 10 is fixedly connected to one end of the swing frame 14, a top rod 15 is rotatably sleeved on each swing frame 14, a plurality of top openings distributed with lamps are opened on the clamping pipe 11, and the outer walls of the upper ends of the top rods 15 respectively pass through the corresponding top openings and are arranged above the clamping pipe 11;

[0028] The jacking and discharging mechanism also includes a fixing plate 17, which is respectively arranged at both sides of the bottom end of the clamping tube 11, and the bottom ends of the two fixing plates 17 are rotatably connected with a connecting belt 16, and the bottom end of the fixing plate 17 is fixedly connected to a second motor 12, and the output end of the second motor 12 is rotatably connected to the connecting belt 16, and a plurality of connecting rods 19 equidistantly distributed are slidably arranged on the outer wall of the connecting belt 16, and two adjacent connecting rods 19 are fixedly connected by a return spring. Both ends of the connecting rod 19 are respectively fixedly connected to a rotating shaft 21, and the rotating shaft 21 is respectively rotatably connected to a first swing rod 18, and the other end of the first swing rod 18 is rotatably connected to a connecting block 22, and one end of the connecting block 22 is rotatably connected to a second swing rod 20, and the other end of the second swing rod 20 is fixedly connected to a sliding rod 13, and the bottom end of the clamping tube 11 is fixedly connected to a fixing plate 24, and the bottom end of the fixing plate 24 is fixedly connected to a V-shaped slide groove 23 that can be slidably connected to the sliding rod 13;

[0029] When the above scheme is put into practical use, after the tube body is transported to the inside of the baffle plate 3 through the conveyor 2, the first motor 10 is started to drive the swing frame 14 inside the clamping tube 11 to rotate, and the rotating swing frame 14 drives the push rod 15 to periodically extend upward from the top opening, and the extended part pushes the tube body originally accumulated at the upper end of the clamping tube 11 to move the accumulated tube body to a movable position, and then enters the clamping tube 11 and is fixed. If the gap between adjacent tube bodies in the clamping tube 11 is very small during the transportation of the tube body inside the clamping tube 11, the tube body that is pushed and accumulated has no gap to be inserted, and the second motor 12 is started to drive the connecting belt 16 to rotate. When the connecting belt 16 rotates, the tube body is moved by the external connecting rod 19. When the connecting rod 19 slides to the upper end of the V-shaped slide groove 23, the bottom ends of the slide bars 13 on both sides of the connecting rod 19 enter the V-shaped slide groove 23, and as the connecting rod 19 slides, the slide bar 13 slides along the V-shaped slide groove 23, so that the first swing bar 18 and the second swing bar 20 in the horizontal position turn around the connecting block 22 The first and second swing arms 21 are rotated and one end of the first swing arm 18 rotates around the rotating shaft 21, so that the connecting rod 19 and the first and second swing arms 20 on both sides form a rhombus, and the first and second swing arms 20 push the tube bodies on both sides of the connecting rod 19, so that the distance between the tube bodies is increased. At this time, in conjunction with the reciprocating motion of the push rod 15, the tube bodies accumulated on the upper end of the clamping tube 11 can be pushed and entered into the inner side of the clamping tube 11 for transportation, and the two adjacent connecting rods 19 are elastically connected by a return spring. After the sliding rod 13 passes through the inside of the V-shaped slide groove 23, the first and second swing arms 18 and 20 return to the horizontal position, and the distance between the two connecting rods 19 is restored. The present invention adopts the push rod 15 that can move the tube bodies accumulated on the upper end of the clamping tube 11, and cooperates with the connecting rod 19 that increases the distance between the tube bodies inside the clamping tube 11, so that the clamping tube 11 will not have the problem of stacking and jamming when transporting the tube bodies, and can ensure that all the tube bodies can be transported neatly, thereby improving production efficiency.

[0030] As a further solution of the present invention, a magnetic attraction block is fixedly connected inside the connecting rod 19, and a metal block capable of being attracted by the magnetic attraction block is embedded at one end of the second swing rod 20;

[0031] When the above solution is put into actual use, through the magnetic attraction block inside the connecting rod 19, when the second swing rod 20 is attached to the connecting rod 19, the connecting rod 19 can adsorb and fix the second swing rod 20 at one end of the connecting rod 19, avoiding the angle deflection of the first swing rod 18 and the second swing rod 20 around the connecting block 22 during the swinging process of the connecting rod 19 along with the connecting belt 16.

[0032] As a further solution of the present invention, the internal heating temperature of the heating channel 5 is about one hundred and fifteen degrees Celsius;

[0033] When the above solution is put into actual use, the heating channel 5 needs to provide sufficient temperature to soften the surface of the pipe body during its transportation inside the heating channel 5, facilitating subsequent blow molding processing.

[0034] As a further solution of the present invention, the pipe body is composed of a connecting pipe, a supporting ring, and a threaded head. The outer walls of the conveying frames 4 are all smooth walls. The gap between the conveying frames 4 is the same as the gap between the clamping pipes 11. The width of the gap is greater than the vertical cross-sectional width of the pipe body and less than the circumferential diameter of the supporting ring on the pipe body;

[0035] When the above solution is put into actual use, through the design of the supporting ring, the pipe body automatically aligns inside the clamping pipe 11. Since the position of the supporting ring is close to the threaded head, the center of gravity of the pipe body is biased upward, that is, the problem of the pipe body being upside down will not occur during the automatic alignment process. The smooth conveying frames 4 will not cause wear to the outer wall of the pipe body during the transportation of the pipe body.

[0036] As a further solution of the present invention, a water cooling channel is opened inside the forming mold 9. A water cooling inlet is opened at the top of the forming mold 9, and a water cooling outlet is opened at the bottom of the forming mold 9;

[0037] When the above solution is put into actual use, the formed plastic bottle inside the forming mold 9 is quickly cooled and formed through the water cooling channel, accelerating the production efficiency of the plastic bottle.

[0038] As a further solution of the present invention, the outer wall of the top end of the ejector rod 15 is in the shape of a chamfered arc, and the outer walls of the ejector rod 15 are all smooth walls;

[0039] When the above solution is put into actual use, when the ejector rod 15 with a chamfered arc shape is pushed upward, the contact part with the pipe body is smooth and will not cause damage to the outer shape of the pipe body.

[0040] Working principle: When producing plastic bottles, the raw materials for production are mixed and heated, extruded into the molding cavity for preliminary molding and then cooled. At this time, the raw materials have a preliminary appearance of a test tube shape. The cooled tube body is transported to the inside of the storage cavity 1, and the tube body is transported to the inside of the baffle plate 3 at the upper end of the clamping tube 11 by the conveyor 2. The tube body passes through the inclined baffle plate 3 during transportation and gradually enters the inside of the clamping tube 11, and is transported in an orderly and uniform direction inside the clamping tube 11;

[0041] When the tube body is transported to the inside of the baffle plate 3 by the conveyor 2, the first motor 10 is started to drive the swing frame 14 inside the clamping tube 11 to rotate, and the rotating swing frame 14 drives the push rod 15 to periodically extend upward from the top opening, and the extended part pushes the tube body originally piled up at the upper end of the clamping tube 11, so that the piled tube body moves to a movable position, and then enters the clamping tube 11 and is fixed. If the gap between adjacent tube bodies in the clamping tube 11 is very small during the transportation of the tube body inside the clamping tube 11, and the piled tube body has no gap to be inserted, the second motor 12 is started to drive the connecting belt 16 to rotate. When the connecting belt 16 rotates, it moves the tube body through the external connecting rod 19. When the connecting rod 19 slides to the upper end of the V-shaped slide groove 23, the bottom ends of the slide bars 13 on both sides of the connecting rod 19 enter the V-shaped slide groove 23 and move along with the connecting rod 19. The sliding of the slide bar 13 makes it slide along the V-shaped slot 23, so that the first swing bar 18 and the second swing bar 20 in horizontal position flip around the connecting block 22, and one end of the first swing bar 18 rotates around the rotating shaft 21, so that the connecting bar 19 and the first swing bar 18 and the second swing bar 20 on both sides form a rhombus, and the first swing bar 18 and the second swing bar 20 push the tube bodies on both sides of the connecting bar 19, so that the distance between the tube bodies increases. At this time, with the reciprocating motion of the push rod 15, the tube bodies accumulated on the upper end of the clamping tube 11 can be pushed and then enter the inner side of the clamping tube 11 for transportation, and the two adjacent connecting rods 19 are elastically connected by a return spring. After the slide bar 13 passes through the inside of the V-shaped slot 23, the first swing bar 18 and the second swing bar 20 return to the horizontal position, and the distance between the two connecting rods 19 is restored;

[0042] The test tube transported by the clamping tube 11 enters the heating channel 5 along the conveying rack 4. After being heated in the heating channel 5, the surface hardness of the tube body is reduced. After the tube body with reduced hardness enters the molding mold 9, the molding mold 9 is closed, and the blowing tube 8 moves down to dock with the opening of the tube body. Low-pressure air is first passed into the tube body and then high-pressure air is introduced so that the tube body fills the molding mold 9. After cooling, it can be made into a plastic bottle.
