Description

Technical Field

[0001] This utility model belongs to the field of plastic bottle processing technology, specifically relating to a device for removing burrs and flash from the mouth of a plastic bottle. Background Technology

[0002] Injection molding is a common process in the production of plastic bottles. However, plastic bottles produced by injection molding often have burrs and flash at the bottle neck. These burrs and flash are mainly due to tiny gaps in the injection mold during the mold closing process. Under high pressure, the molten plastic is forced into these gaps, and after cooling, it forms excess plastic scraps.

[0003] The presence of these burrs and flash has multiple negative impacts. From a product quality perspective, burrs and flash on the bottle neck affect the seal of the cap, making it prone to leakage when containing liquid products. This is an extremely serious problem for product packaging in the food, beverage, and cosmetic industries, directly affecting the product's shelf life and market image. From a production efficiency perspective, additional manpower or equipment is needed to remove the burrs and flash, increasing production steps and time costs. When manually removing burrs and flash, the consistency of worker operation is difficult to guarantee, which can easily lead to incomplete removal or over-grinding, damaging the bottle neck and further reducing the product yield.

[0004] Authorized publication number "CN221984688U" describes a deburring device for plastic bottles, including an operating table, a support frame, several deburring components, and a placement rack. The support frame is located at the top rear end of the operating table, and several lifting components are arranged on the front upper part of the support frame. The deburring components are arranged on the connecting parts of the lifting components, and the lifting components are used for lifting the deburring components. The placement rack is slidably arranged on the top of the operating table corresponding to the lower part of the deburring components. Several placement holes are provided through the top of the placement rack for placing plastic bottles. The grinding part of the deburring components is arranged corresponding to the bottle mouth of the plastic bottles. It can simultaneously perform deburring and grinding treatment on the bottle mouths of multiple plastic bottles, effectively covering all angles of the bottle mouth, effectively removing burrs at the bottle mouth, improving the convenience of operation, and improving the efficiency of plastic bottle deburring.

[0005] The aforementioned patented deburring assembly has a grinding section designed to correspond to the bottle mouth of a plastic bottle. It can simultaneously perform deburring and grinding on multiple plastic bottles, effectively covering all angles of the bottle mouth and effectively removing burrs, improving operational convenience and efficiency in deburring plastic bottles. However, the aforementioned patent has certain limitations in use. It cannot adjust the distance between the blade and the bottle mouth according to actual needs, making it difficult to ensure that the blade can accurately remove burrs and flash without damaging the bottle mouth. This results in the blade being difficult to adapt to plastic bottle mouths and plastic bottles of different sizes. This problem limits the versatility and practicality of the device, fails to meet diverse production needs, and also increases operational complexity and production costs. Utility Model Content

[0017] The second limiting groove is provided in three parts, and all three second limiting grooves are opened at the bottom end of the lower connecting cover.

[0018] Three movable plates are provided, and the three movable plates are slidably connected in three second limiting grooves respectively, and the three movable plates are fixedly connected to the top of three sector plates respectively;

[0019] The T-shaped groove is provided in three places. The three T-shaped grooves are fixedly connected to the bottom ends of three movable plates respectively, and the three cutting tools are movably engaged in the three T-shaped grooves respectively.

[0036] 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.

[0037] Example 1

[0038] Please see Figures 1-3 The present invention provides the following technical solution:

[0039] A device for removing burrs and flash from the neck of a plastic bottle, comprising:

[0040] A connecting platform 1 is provided. An L-shaped plate 2 is fixedly connected to the top of the connecting platform 1. A cylinder 3 is fixedly connected to the bottom of the L-shaped plate 2. A connecting plate 4 is fixedly connected to the telescopic end of the cylinder 3. An upper connecting cover 15 is rotatably connected to the bottom of the connecting plate 4. A second gear 13 is fixedly connected to the circumferential surface of the upper connecting cover 15. A first gear 12 is rotatably connected inside the connecting plate 4. The first gear 12 and the second gear 13 mesh with each other. A first motor 5 is fixedly connected to the top of the connecting plate 4. The output end of the first motor 5 is fixedly connected to the first gear 12. A limit hole 8 is provided at the bottom of the connecting platform 1. A clamp 9 is installed in the limit hole 8.

[0041] Three cutting tools 20 are provided, all three cutting tools 20 being located on the lower side of the lower connecting cover 14; and

[0042] An adjustment mechanism is located on the lower side of the lower connecting cover 14. The adjustment mechanism is used to adjust the position of the three cutting tools 20.

[0043] In a specific embodiment of this utility model, the L-shaped plate 2 is fixedly connected to the connecting platform 1 for mounting the cylinder 3. This changes the direction of force transmission, allowing the cylinder 3 to be mounted at a suitable height and position, so that the extension and retraction of the cylinder 3 can be converted into a vertical force on the related components below, providing a structural basis for subsequent processing of the plastic bottle opening.

[0044] The cylinder 3, through the reciprocating motion of its telescopic end, drives the connecting plate 4 and the upper connecting cover 15 connected to the connecting plate 4 to move up and down. It can precisely control the stroke and speed of the up and down movement, thereby achieving precise adjustment of the processing position of the plastic bottle mouth. For example, it can adjust the cutting blade 20 to a suitable height according to the burrs and flash of different heights.

[0045] The connecting plate 4 transmits the telescopic movement of the cylinder 3 to the upper connecting cover 15, and at the same time, the first gear 12 is installed inside it, providing space for the installation and rotation of the first gear 12. Furthermore, by rotating the upper connecting cover 15, the upper connecting cover 15 can move up and down with the connecting plate 4 while rotating itself, thus meeting the complex motion requirements of the device during operation.

[0046] The upper connecting cap 15 is used to connect to the mouth of the plastic bottle. Under the action of the first motor 5 and the first gear 12 and the second gear 13 of the gear transmission, the mouth of the plastic bottle is driven to rotate. It provides a stable connection structure for the plastic bottle, ensuring that the mouth of the plastic bottle can maintain a stable rotation state during the cutting of burrs and flash, so that the cutting tool 20 can remove the burrs and flash evenly and effectively.

[0047] The second gear 13 is fixedly connected to the circumferential surface of the upper connecting cover 15 and meshes with the first gear 12 to realize the transmission of power. When the first gear 12 rotates under the drive of the first motor 5, it transmits torque to the upper connecting cover 15 through meshing with the second gear 13, thereby driving the upper connecting cover 15 and the bottle mouth connected thereto to rotate. It is one of the key transmission components to realize the rotation of the bottle mouth of the plastic bottle.

[0048] The second gear 13 is fixedly connected to the circumferential surface of the upper connecting cover 15 and meshes with the first gear 12 to realize the transmission of power. When the first gear 12 rotates under the drive of the first motor 5, it transmits torque to the upper connecting cover 15 through meshing with the second gear 13, thereby driving the upper connecting cover 15 and the bottle mouth connected thereto to rotate. It is one of the key transmission components to realize the rotation of the bottle mouth of the plastic bottle.

[0049] The first gear 12 is installed inside the connecting plate 4 and fixedly connected to the output end of the first motor 5, while meshing with the second gear 13. As an intermediate transmission component for the power output of the first motor 5, it converts the rotational motion of the first motor 5 into the rotational motion of the upper connecting cover 15. Through the meshing transmission of the gears, the speed can be adjusted and the torque can be amplified to meet the cutting needs of bottle mouths of plastic bottles of different materials and thicknesses.

[0050] The output shaft of the first motor 5 drives the first gear 12 to rotate at high speed, which in turn drives the upper connecting cap 15 and the bottle mouth of the plastic bottle to rotate through gear transmission. The speed and stability of the first motor 5 directly affect the rotation speed and cutting effect of the bottle mouth of the plastic bottle. By controlling the speed of the first motor 5, the cutting efficiency and quality can be adjusted.

[0051] A limiting hole 8 is provided at the bottom of the connecting platform 1, providing space for the installation and positioning of the clamp 9. The size and shape of the limiting hole 8 match the clamp 9, ensuring that the clamp 9 can be accurately installed on the connecting platform 1, and limiting the position of the clamp 9 during the operation of the device to prevent displacement of the clamp 9 and ensure the clamping stability of the plastic bottle;

[0052] The clamp 9 is installed in the limiting hole 8 to hold the plastic bottle. It can be adjusted according to the size and shape of the plastic bottle to provide sufficient clamping force, ensuring that the plastic bottle remains in a stable position during the cutting of burrs and flash, without shaking or displacement, thereby ensuring the accuracy and quality of the cutting;

[0053] Three cutting blades 20 are provided, located below the lower connecting cap 14, and are components that directly remove burrs and flash from the bottle neck of the plastic bottle. During the rotation of the plastic bottle neck, the cutting blades 20 can cut the burrs and flash from the bottle neck, removing excess plastic scraps;

[0054] The adjustment mechanism is located on the lower side of the lower connecting cover 14 and is used to adjust the position of the three cutting blades 20. It can flexibly adjust the relative position between the cutting blades 20 and the bottle mouth of the plastic bottle according to the size of the bottle mouth, the distribution of burrs and flash, and the cutting requirements;

[0055] It should be noted that the specific model of the first motor 5, the vacuum cleaner 10, and the infrared sensor 25 used shall be selected by those skilled in the art. Furthermore, the first motor 5, the vacuum cleaner 10, and the infrared sensor 25 mentioned above are all existing technologies and will not be elaborated upon in this solution.

[0056] Please refer to the details. Figures 1-3 The regulating mechanism includes:

[0057] The first bevel gear 23 is rotatably connected to the upper connecting cover 15;

[0058] The second bevel gear 24, there are three second bevel gears 24, the three second bevel gears 24 are respectively rotatably connected to the lower connecting cover 14 and the upper connecting cover 15, and the first bevel gear 23 and the three second bevel gears 24 mesh with each other;

[0059] Spiral plate 26 is fixedly connected to the top of the first bevel gear 23;

[0060] There are three sector plates 17, and all three sector plates 17 are meshed and connected to the circumferential surface of the spiral plate 26.

[0061] The second limiting groove 16, there are three second limiting grooves 16, and all three second limiting grooves 16 are opened at the bottom end of the lower connecting cover 14.

[0062] Three movable plates 18 are provided, and the three movable plates 18 are slidably connected in three second limiting grooves 16 respectively. The three movable plates 18 are fixedly connected to the top of three sector plates 17 respectively.

[0063] T-slots 19, three T-slots 19 are provided, the three T-slots 19 are fixedly connected to the bottom ends of the three movable plates 18 respectively, and the three cutting blades 20 are movably engaged in the three T-slots 19 respectively;

[0064] The second motor 22 is fixedly connected to the circumferential surface of the upper connecting cover 15.

[0065] In this embodiment: when it is necessary to adjust the position of the cutting blade 20 to accommodate the bottle openings of different sizes of plastic bottles, the second motor 22 is started. The output shaft of the second motor 22 drives the first bevel gear 23 to start rotating at its rotational connection with the upper connecting cover 15. Since the first bevel gear 23 meshes with three second bevel gears 24, the rotation of the first bevel gear 23 will drive the three second bevel gears 24 to rotate at their respective rotational connections with the lower connecting cover 14 and the upper connecting cover 15, thus realizing the split transmission of power.

[0066] As the first bevel gear 23 rotates, the spiral plate 26 fixedly connected to its top also rotates synchronously. The spiral structure of the spiral plate 26 meshes with the three sector plates 17. During the rotation of the spiral plate 26, the sector plates 17 will move in a straight line along the spiral trajectory of the spiral plate 26. Since the sector plates 17 are connected to the moving plate 18, the linear movement of the sector plates 17 drives the moving plate 18 to slide within the second limiting groove 16.

[0067] During the sliding process, the movable plate 18 drives the cutting tool 20, which is fixedly connected in the T-shaped groove 19 at its bottom end, to adjust its position. In this way, the relative position between the cutting tool 20 and the bottle mouth can be flexibly adjusted according to the size of the plastic bottle mouth, the distribution of burrs and flash, and the cutting requirements. For example, the radial position of the cutting tool 20 can be adjusted to accommodate plastic bottle mouths of different diameters, or the axial position of the cutting tool 20 can be adjusted to accommodate burrs and flash of different heights. This improves the adaptability of the device to plastic bottles of different specifications and expands the application range of the device.

[0068] Please refer to the details. Figures 1-3 The top of the connecting platform 1 is fixedly connected to an arc-shaped sleeve 6 and a vacuum cleaner 10. The air inlet pipe of the vacuum cleaner 10 is connected to the arc-shaped sleeve 6. A mesh 7 is fixedly connected to the inner circumference of the arc-shaped sleeve 6.

[0069] In this embodiment, the arc-shaped sleeve 6 at the top of the connecting platform 1 cooperates with the vacuum cleaner 10. When the cutting blade 20 cuts the mouth of the plastic bottle, a large amount of plastic debris is generated. The vacuum cleaner 10 starts and generates suction through the air inlet pipe connected to the arc-shaped sleeve 6. The arc-shaped sleeve 6 covers the area near the cutting area, effectively collecting the debris generated during cutting, preventing it from flying around, and improving the working environment. The mesh 7 is fixed to the inner circumference of the arc-shaped sleeve 6, serving as a filter to prevent larger plastic debris from entering the vacuum cleaner 10, protecting the internal structure of the vacuum cleaner 10, and extending its service life.

[0070] Please refer to the details. Figure 2 The front end of the connecting platform 1 is provided with a first limiting groove 101, and the front end of the connecting platform 1 is movably hinged to a cover plate 102 via a hinge shaft. The cover plate 102 is movably engaged in the first limiting groove 101.

[0071] In this embodiment, the cover plate 102 is movably engaged within the first limiting groove 101, sealing the front end of the connecting platform 1. This prevents debris from falling from the front end of the connecting platform 1 during the deburring process, keeping the work area clean. When maintenance or cleaning of the components inside or below the connecting platform 1 is required, the cover plate 102 can be opened and rotated via the hinge to disengage it from the first limiting groove 101, facilitating operation of the internal components by the operator.

[0072] Please refer to the details. Figures 1-3 Infrared sensors 25 are fixedly connected to the bottom of each of the three movable plates 18.

[0073] In this embodiment, infrared sensors 25, which are fixedly connected to the bottom ends of the three movable plates 18, play an important role in the operation of the device. Once the plastic bottle is placed on the clamp 9 and secured, the infrared sensors 25 begin to operate. They can sense the relative positional relationship between the bottle opening and the cutting blade 20.

[0074] Please refer to the details. Figures 1-3 Each of the three T-slots 19 has two bolts 21 threadedly connected to it, and one end of each of the six bolts 21 is threadedly connected to the three cutting tools 20 through the threaded holes of the three T-slots 19.

[0075] In this embodiment, two bolts 21 are threaded into each of the three T-slots 19, and one end of each of the six bolts 21 is threaded into one of the three cutting blades 20 through the threaded holes of the three T-slots 19. This connection method allows the cutting blades 20 to be stably installed in the T-slots 19. When it is necessary to replace the cutting blades 20 to accommodate different materials of plastic bottles or different types of burrs and flash, the operator can unscrew the bolts 21 to remove them from the cutting blades 20, thereby easily removing the old cutting blades 20 and installing the new ones.

[0076] Please refer to the details. Figures 1-3 A height measuring ruler 11 is fixedly connected to one end of the L-shaped plate 2.

[0077] In this embodiment, the height measuring ruler 11 fixedly connected to one end of the L-shaped plate 2 provides the operator with an intuitive height reference. Before the device is in operation, when it is necessary to adjust the position of the cutting blade 20 according to the bottle opening of plastic bottles of different heights, the operator can observe the height measuring ruler 11 and, in combination with the actual height of the plastic bottle, accurately adjust the extension and retraction of the cylinder 3, thereby driving the connecting plate 4, the upper connecting cover 15, and the cutting blade 20 to move up and down, so that the cutting blade 20 reaches the appropriate height position.

[0078] The working principle and usage process of this utility model are as follows: First, adjust the clamp 9 according to the size of the plastic bottle and install it in the limiting hole 8 at the bottom of the connecting platform 1 to place and clamp the plastic bottle. Then, observe the height measuring ruler 11 on one side of the L-shaped plate 2 and adjust the extension and retraction of the cylinder 3 according to the height of the plastic bottle to make the cutting tool 20 reach the appropriate height. Then, start the first motor 5, which drives the first gear 12 to rotate, and through gear transmission, the upper connecting cap 15 and the bottle mouth of the plastic bottle rotate. If it is necessary to adjust the position of the cutting tool 20 to adapt to different specifications of plastic bottles, start the second motor 22, which drives the first bevel gear 23 to rotate. Through meshing with the second bevel gear 24, the power is transmitted in different directions, which in turn makes the spiral plate 26 rotate, drives the fan-shaped plate 17 to move linearly, and causes the moving plate 18 to slide in the second limiting groove 16, finally adjusting the position of the cutting tool 20. Then, the cutting tool 20 cuts the burrs and flash of the rotating bottle mouth. During cutting, the dust collection device 10 is started, and the arc sleeve 6 and the mesh 7 are used to collect and filter debris. In terms of equipment maintenance, the internal components can be operated by opening the cover plate 102 at the front end of the connecting platform 1; the cutting tool 20 can be replaced by rotating the bolt 21 in the T-slot 19. In addition, the infrared sensor 25 at the bottom of the moving plate 18 senses the position relationship between the bottle mouth and the tool in real time to ensure accurate cutting without damaging the bottle mouth.

[0079] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
