Description

Technical Field

[0001] This utility model relates to the field of plastic bottle cap production technology, specifically to an injection molding machine for producing plastic bottle caps. Background Technology

[0002] Plastic bottle caps are a common sealing method for bottles, cans, and barrels, especially in the beverage, chemical, and pharmaceutical industries. Based on their use, they can be divided into breathable and non-breathable plastic caps. Generally, plastic caps have a ring-shaped leak-proof ring on the inner wall of the top. Some ordinary plastic barrel caps require an inner cap and therefore do not need a leak-proof ring. The lower end of the plastic cap is connected to an anti-theft ring via a tensile reinforcing rib. Several sheet-like rotating tensile wings are evenly distributed on the inner wall of the anti-theft ring. Plastic barrel caps designed in this way have a strong seal, good leak-proof and anti-theft performance, are safe and convenient to use, effectively prevent the liquid inside the container from being contaminated by external sources, and ensure that the packaging of various liquid products meets national safety standards.

[0003] The existing authorization announcement number CN212860183U discloses an injection molding machine for producing plastic bottle caps, comprising a main body, a base cabinet provided on the lower outer surface of the main body, a feeding bin provided on the upper outer surface of the base cabinet, and a mold-locking bin provided on one side of the feeding bin. This utility model of an injection molding machine for producing plastic bottle caps is equipped with a convenient material receiving mechanism and an odor removal mechanism. During operation, the connecting housing can be moved to the lower end of the discharge port via casters to receive the injection-molded bottle caps. After receiving, the receiving box can be pulled out for convenient unloading. The odor removal mechanism allows the sealing plug to be removed before the injection molding machine starts operating, and odor-removing activated carbon to be placed inside the housing. The activated carbon absorbs odors inside the mold-locking bin through a volatilization tank, preventing excessive odors from affecting usability and improving future usability.

[0004] Existing injection molding machines for producing plastic bottle caps have the following problems: when there is a lot of material being processed during the injection molding of plastic bottle caps, it will accumulate inside the barrel. This accumulation will cause the processed material to clump together and block the outlet, which will affect the production speed of plastic bottle caps. To address this, we propose an injection molding machine for producing plastic bottle caps. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide an injection molding machine for producing plastic bottle caps. When injecting plastic bottle caps, the material inside the barrel is stirred to prevent material accumulation from clogging the outlet and thus avoid affecting the production speed of plastic bottle caps. This can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an injection molding machine for producing plastic bottle caps, comprising a machine base, an adapter box at the upper end of the machine base, a material inlet at the upper end of the adapter box being connected to a material cylinder via a connecting pipe, a spiral conveying pipe at the rear end of the adapter box, and mold one and mold two arranged sequentially from front to back on the rear side of the upper end of the machine base, and also including a stirring mechanism.

[0007] The stirring mechanism includes a support shaft, a rotating cylinder, bevel gear one, bevel gear two, sleeves, stirring rods, stirring levers, and a lower stirring lever. A protective cover is provided at the upper end of the cylinder. The rotating cylinder is rotatably connected to the middle of the top wall of the cylinder. The support shaft is located inside the rotating cylinder, coinciding with the central axis of the rotating cylinder. The top end of the support shaft is fixedly connected to the top wall of the protective cover. Uniformly distributed sleeves are fixedly connected to the outer wall of the rotating cylinder. Stirring rods are rotatably connected inside each sleeve. A lower stirring lever is fixedly connected to the lower end of the rotating cylinder. Uniformly distributed stirring levers are fixedly connected to the outer surface of the lower stirring lever. Bevel gear two is fixedly connected to one end of each stirring lever inside the rotating cylinder near the central axis of the rotating cylinder. Uniformly distributed bevel gear one is fixedly sleeved on the outer surface of the support shaft inside the rotating cylinder. Three bevel gear twos at the same horizontal height are all meshed with bevel gear one. During the injection molding of plastic bottle caps, the material inside the cylinder is stirred to prevent material accumulation from clogging the outlet and thus avoiding affecting the production speed of the plastic bottle caps.

[0008] Furthermore, the machine tool is equipped with a control switch group on its exterior. The input terminal of the control switch group is electrically connected to an external power source to provide electrical connections for various electrical appliances.

[0009] Furthermore, the stirring mechanism also includes a drive assembly, which includes a slide rail, a slide bar, a rack and a gear. The outer surface of the rotating cylinder located inside the protective cover is fixedly fitted with a gear. The upper end of the cylinder is provided with a slide rail, and a slide bar is slidably connected inside the slide rail. A rack is provided on the upper left side of the slide bar, and the rack meshes with the gear to provide a rotational connection.

[0010] Furthermore, the drive assembly also includes a rotating column, a turntable, a sliding column, and a sliding groove. A support plate is provided on the right side of the upper end of the slide bar, and a sliding groove is provided at the upper end of the support plate. The top wall of the protective cover is rotatably connected to the rotating column, the lower end of the rotating column is fixedly connected to the turntable, and the lower edge of the turntable is fixedly connected to the sliding column. The outer surface of the sliding column is slidably connected to the inner wall of the sliding groove to provide a rotatable connection.

[0011] Furthermore, the drive assembly also includes a second motor, which is disposed at the upper end of the protective cover. The lower end of the output shaft of the second motor is fixedly connected to the upper end of the rotating column, and the input end of the second motor is electrically connected to the output end of the control switch group to provide rotation drive.

[0012] Furthermore, the rear end of the machine tool is provided with a support plate, and guide rods are slidably connected inside the sliding holes at the front end of the support plate.

The input end of the first motor is electrically connected to the output end of the control switch group to provide injection driving.

[0013] Furthermore, a feed pipe is provided at the feed inlet at the upper end of the barrel to facilitate feeding.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This injection molding machine for producing plastic bottle caps has the following advantages:

[0015] Driven by motor two, the rotating column rotates, causing the sliding column on the turntable to perform compound motion within the sliding groove. When the sliding column is at the twelve o'clock position, it drives the support plate to move backward, and when it is at the six o'clock position, the support plate moves forward. This reciprocating motion causes the sliding bar to slide back and forth within the slide rail. Through the meshing of the rack and pinion, the rotating cylinder rotates alternately in both directions, and the stirring rod and stirring bar fixed on it stir the material in the cylinder in all directions. At the same time, the rotation of the rotating cylinder, through the meshing of bevel gear one and bevel gear two, drives the stirring rod to rotate in both directions in the sleeve. This three-dimensional stirring method effectively prevents material accumulation and ensures smooth production. When injection molding plastic bottle caps, by stirring the material inside the cylinder, material accumulation is prevented from clogging the outlet and avoiding affecting the production speed of plastic bottle caps.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4This embodiment provides a technical solution: an injection molding machine for producing plastic bottle caps, including a machine base 1, a transfer box 3 at the upper end of the machine base 1, a material inlet at the upper end of the transfer box 3 connected to a material cylinder 5 via a connecting pipe 4, a spiral conveying pipe 7 at the rear end of the transfer box 3, and uniformly distributed heating rings at the outer rear end of the spiral conveying pipe 7, mold 1 8 and mold 2 9 arranged sequentially from front to back on the rear side of the upper end of the machine base 1, and a stirring mechanism 6, a control switch group 13 on the outside of the machine base 1, the input end of the control switch group 13 being electrically connected to an external power source, a support plate 10 at the rear end of the machine base 1, and guide rods 11 slidably connected inside the sliding holes at the front end of the support plate 10. The front ends of all components are fixedly connected to the rear ends of mold 2 9. The rear end of the spiral conveyor pipe 7 is connected to the middle of the front end of mold 1 8.

The rear end of the support plate 10 is equipped with hydraulic rod 12, and the telescopic end of hydraulic rod 12 is fixedly connected to the middle of the rear end of mold 2 9. The input end of motor 1 2 is electrically connected to the output end of control switch group 13. The feed inlet of the upper end of the material cylinder 5 is equipped with feed pipe 15. In the production process of plastic bottle caps, the material conveying and processing flow is as follows: First, the processing material is injected into the material cylinder 5 through feed pipe 15, and then falls to the spiral conveyor pipe 7 through connecting pipe 4. At this time, the operator can start motor 1 2 through control switch group 13. The output shaft of motor 1 2 drives the spiral conveyor rod to rotate. Using the propulsive action of the spiral blades, the processing material is conveyed backward in the spiral conveyor pipe 7. When the material passes through the heating ring, it will be heated to a molten state, and then pushed between mold 1 8 and mold 2 9 for injection molding. After injection molding is completed, the external hydraulic cylinder depressurizes the hydraulic rod 12, and the telescopic end of the hydraulic rod 12 drives the mold 2 9 to move backward, which, together with the push rod at the front end of the support plate 10, realizes the demolding of the bottle cap.

[0023] The stirring mechanism 6 includes a support shaft 61, a rotating cylinder 62, a first bevel gear 63, a second bevel gear 64, a sleeve 65, a stirring rod 66, a stirring arm 67, and a lower stirring rod 68. A protective cover 14 is provided at the upper end of the material cylinder 5. The rotating cylinder 62 is rotatably connected to the middle of the top wall of the material cylinder 5. The support shaft 61 is located inside the rotating cylinder 62, and the support shaft 61 coincides with the central axis of the rotating cylinder 62. The top end of the support shaft 61 is fixedly connected to the top wall of the protective cover 14. Uniformly distributed sleeves 65 are fixedly connected to the outer wall of the rotating cylinder 62. Stirring rods 66 are rotatably connected inside the sleeves 65. The lower end of the rotating cylinder 62 is fixedly connected to the lower stirring rod 68. The outer surface of the stirring rod 68 is fixedly connected with uniformly distributed stirring rods 67. Inside the rotating cylinder 62, the stirring rod 66 near the central axis of the rotating cylinder 62 is fixedly connected with bevel gears 64. The outer surface of the support shaft 61 inside the rotating cylinder 62 is fixedly fitted with uniformly distributed bevel gears 63. Three bevel gears 64 at the same horizontal height are meshed with bevel gears 63. The stirring mechanism 6 also includes a drive assembly 69, which includes a slide rail 696, a slide bar 697, a rack 698, and gears 699. Gears 699 are fixedly fitted on the outer surface of the rotating cylinder 62 inside the protective cover 14. The upper end of the material cylinder 5 is equipped with... The drive assembly 69 includes a slide rail 696, with a slide bar 697 slidably connected inside the slide rail 696. A rack 698 is located on the upper left side of the slide bar 697, meshing with a gear 699. The drive assembly 69 also includes a rotating column 692, a turntable 693, a slide column 694, and a slide groove 695. A support plate is located on the upper right side of the slide bar 697, with a slide groove 695 at its upper end. The top wall of the protective cover 14 is rotatably connected to the rotating column 692, with the turntable 693 fixedly connected to its lower end. A slide column 694 is fixedly connected to the lower edge of the turntable 693, with its outer surface slidably connected to the inner wall of the slide groove 695. 9 also includes a second motor 691, which is located on the upper end of the protective cover 14. The lower end of the output shaft of the second motor 691 is fixedly connected to the upper end of the rotating column 692. The input end of the second motor 691 is electrically connected to the output end of the control switch group 13. In order to address the problem of material accumulation and blockage that may occur during production, the equipment is designed with an intelligent anti-blockage system. When there is too much material in the material cylinder 5, the operator starts the second motor 691 through the control switch group 13. Its output shaft drives the rotating column 692 to rotate, which in turn drives the sliding column 694 on the turntable 693 to perform compound motion in the slide groove 695. When the sliding column 694 is at the twelve o'clock position, it drives the support plate to move backward.When rotated to the six o'clock position, the support plate moves forward. This reciprocating motion causes the slide bar 697 to slide back and forth within the slide rail 696. Through the meshing transmission of the rack 698 and gear 699, the rotating cylinder 62 is driven to rotate alternately in both directions. This causes the stirring rod 66 and stirring arm 67 fixed on it to perform all-round stirring of the material in the material cylinder 5. At the same time, the rotation of the rotating cylinder 62, through the meshing of bevel gear 1 63 and bevel gear 2 64, drives the stirring rod 66 to rotate in both directions in the sleeve 65. This three-dimensional stirring method effectively avoids material accumulation and ensures the smooth operation of the production process.

[0024] The working principle of the injection molding machine for producing plastic bottle caps provided by this utility model is as follows: In the production process of plastic bottle caps, the material conveying and processing flow is as follows: First, the processing material is injected into the material cylinder 5 through the feed pipe 15, and then falls into the spiral conveying pipe 7 through the connecting pipe 4. At this time, the operator can start the motor 2 through the control switch group 13. The output shaft of the motor 2 drives the spiral conveying rod to rotate. Using the propulsive action of the spiral blade, the processing material is conveyed backward in the spiral conveying pipe 7. When the material passes through the heating ring, it will be heated to a molten state, and then pushed between the mold 8 and the mold 9 for injection molding. After injection molding is completed, the external hydraulic cylinder depressurizes the hydraulic rod 12. The telescopic end of the hydraulic rod 12 drives the mold 9 to move backward. With the help of the push rod at the front end of the support plate 10, the bottle cap is demolded. In order to address the material accumulation and blockage problem that may occur during production, the equipment is designed with intelligent anti-blockage. In this system, when there is too much material in the material cylinder 5, the operator starts the motor 691 by controlling the switch group 13. Its output shaft drives the rotating column 692 to rotate, which in turn drives the sliding column 694 on the turntable 693 to perform compound motion in the slide groove 695. When the sliding column 694 is at the twelve o'clock position, it drives the support plate to move backward; when it rotates to the six o'clock position, the support plate moves forward. This reciprocating motion causes the sliding bar 697 to slide back and forth in the slide rail 696. Through the meshing transmission of the rack 698 and the gear 699, the rotating cylinder 62 is driven to rotate alternately in both directions, so that the stirring rod 66 and the stirring rod 67 fixed on it can stir the material in the material cylinder 5 in all directions. At the same time, the rotation of the rotating cylinder 62 drives the stirring rod 66 to rotate in both directions in the sleeve 65 through the meshing of the bevel gear 63 and the bevel gear 64. This three-dimensional stirring method effectively avoids material accumulation and ensures the smooth operation of the production process.

[0025] It is worth noting that, in the above embodiments, the motor 2 and the motor 691 disclosed can be either D180M-0160030B-E or YJ61. The control switch group 13 is provided with a switch button that corresponds one-to-one with the motor 2 and the motor 691 and is used to control their switching operation.

[0026] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model.
