Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic bottle processing technology, and in particular to a plastic bottle mouth cutting device. Background Technology
[0002] Plastic bottles are mainly made of materials such as polyethylene or polypropylene with the addition of various organic solvents. Plastic bottles widely use polyester, polyethylene, and polypropylene as raw materials. After adding the corresponding organic solvents, they are heated at high temperature and then formed into plastic containers through plastic molds by blow molding, extrusion blow molding, or injection molding. Some plastic bottles need to have their bottle mouths cut with a cutting machine after blow molding.
[0003] Chinese utility model patent CN219360286U discloses a plastic bottle neck cutting machine, including a housing, a cutting device, a clamping and fixing device, and an adjusting device. The cutting device is slidably mounted on the housing via a sliding component. The clamping and fixing device and the adjusting device are spaced apart on the housing. The cutting end of the cutting device can move horizontally in the front-back direction at the clamping end side of the clamping and fixing device to cut the neck of the plastic bottle held by the clamping and fixing device. The adjusting device is located on the side of the clamping and fixing device away from the cutting device, and the adjusting end of the adjusting device can drive the plastic bottle held by the clamping and fixing device to move from left to right.
[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: the device can only position and clamp a single plastic bottle in a single operation. When continuous processing of a batch of plastic bottles is required, the single clamping structure design results in frequent clamping operations, leading to a large amount of ineffective waiting time during equipment operation and thus low production efficiency. Utility Model Content
[0005] To solve the above problems, this utility model provides a plastic bottle mouth cutting device.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a plastic bottle neck cutting device, including a frame, a worktable on the top of the frame, two columns spaced apart on the top surface of the worktable, a lifting plate slidably mounted on the two columns, a plurality of clamping components on the worktable, the clamping components including a mounting plate on the worktable, four support columns arranged in a rectangular array on the top surface of the mounting plate, a lower clamping plate in an overall V-shape on the four support columns, two connecting columns on the bottom surface of the lifting plate, an upper clamping plate corresponding to the lower clamping plate and in an inverted V-shape at the lower end of the two connecting columns, the length of the upper clamping plate being less than the length of the lower clamping plate, clearance grooves being provided on both sides of the lower clamping plate corresponding to the upper clamping plate, a cutting component on the worktable, and a limiting component for limiting the horizontal position of the plastic bottle on the side of the worktable away from the cutting component on the mounting plate.
[0007] By adopting the above technical solution, a worktable, lifting plate, clamping assembly, cutting assembly, and limiting assembly are set up. The plastic bottle is placed on the lower clamping plate with its opening facing the cutting assembly. The lifting plate descends, causing the connecting column and upper clamping plate to descend as well, clamping the plastic bottle between the lower and upper clamping plates. When the plastic bottle is clamped, the lower clamping plate supports the lower sides of the bottle, while the upper clamping plate contacts the upper sides of the bottle. For plastic bottles of different diameters, the descent distance of the lifting plate and upper clamping plate is adjusted, thereby adjusting the distance between the upper and lower clamping plates to ensure that the upper clamping plate contacts the top of the plastic bottle, thus enabling the fixing of plastic bottles of different diameters. The limiting assembly limits the horizontal position of the plastic bottle, ensuring that the bottle opening is flush, thereby ensuring the consistency of the cutting assembly's cut at the bottle opening. The system can clamp the same number of plastic bottles as the clamping assembly simultaneously, avoiding frequent clamping operations that waste time and improving production efficiency.
[0008] Furthermore, a top plate is provided at the upper end of both columns, and an electric push rod is vertically provided on the top plate. The piston rod of the electric push rod passes downward through the top plate and connects with the top surface of the lifting plate.
[0009] By adopting the above technical solution, a top plate and an electric push rod are installed, and the lifting plate is raised and lowered by the electric push rod.
[0010] Furthermore, the limiting component includes mounting columns spaced apart on the worktable, with a fixing block at the upper end of the two mounting columns. A sliding hole is horizontally opened on the fixing block corresponding to the lower clamping plate, and a sliding rod is slidably arranged in the sliding hole. A limiting plate is provided at one end of the sliding rod near the lower clamping plate.
[0011] By adopting the above technical solution, a mounting column, a fixing block, a sliding rod, and a limiting plate are set up. The sliding rod moves the position of the limiting plate. When the plastic bottle is placed, its bottom end contacts the limiting plate, thereby restricting the horizontal position of the plastic bottle.
[0012] Furthermore, a connecting rod is provided at the end of several sliding rods away from the lower clamping plate. A threaded hole is vertically opened on the fixing block. The threaded hole communicates with one of the sliding holes, and the axial direction of the threaded hole is perpendicular to the axial direction of the sliding hole. A threaded rod is spirally arranged in the threaded hole, and a handle is provided at the upper end of the threaded rod.
[0013] By adopting the above technical solution, a connecting rod, a threaded rod, and a handle are provided. Pulling the connecting rod will drive several sliding rods to move synchronously, making the adjustment of the limit plate more convenient. After adjustment, turning the handle will drive the threaded rod to rotate. When the threaded rod rotates, it moves relative to the sliding rod. When the lower end of the threaded rod abuts against the corresponding sliding rod, the position of that sliding rod is fixed, thereby fixing the position of the connecting rod, and consequently fixing the positions of the remaining sliding rods.
[0014] Furthermore, the cutting assembly includes an electric slide horizontally mounted on the worktable. The slide of the electric slide has a mounting base, and the mounting base has a horizontally arranged circular hole. A rotating shaft is rotatably mounted inside the circular hole. A saw blade is mounted on one end of the rotating shaft near the lower clamping plate. A drive motor is horizontally mounted on the mounting base, and the output shaft of the drive motor is connected to the rotating shaft.
[0015] By adopting the above technical solution, an electric slide table, mounting base, rotating shaft, saw blade, and drive motor are set up. The drive motor drives the rotating shaft to rotate, which in turn drives the saw blade to rotate. The horizontal movement of the slide table causes the mounting base, drive motor, and saw blade to move, thereby cutting several plastic bottles.
[0016] Furthermore, one of the slide bars is provided with a plurality of graduated grooves spaced apart along its length.
[0017] By adopting the above technical solution, several scale grooves are set on one of the slide rods. By observing the scale grooves exposed at the opening of the slide hole on the slide rod, the position of the limiting plate can be determined, making adjustment more convenient.
[0018] Furthermore, two rubber sheets are symmetrically arranged on the bottom surface of the upper clamping plate.
[0019] Furthermore, the bottom surface of the rubber sheet is provided with several rubber protrusions.
[0020] Furthermore, an inclined frame is provided on the top of the frame, and the worktable is connected to the top of the inclined frame. The side of the worktable near the cutting component is higher than the side near the limiting component.
[0021] In summary, this utility model has the following beneficial effects: This application includes a worktable, a lifting plate, a clamping assembly, a cutting assembly, and a limiting assembly. A plastic bottle is placed on the lower clamping plate with its opening facing the cutting assembly. The lifting plate descends, causing the connecting column and the upper clamping plate to descend as well, clamping the plastic bottle between the lower and upper clamping plates. When the plastic bottle is clamped, the lower clamping plate supports the lower sides of the bottle, while the upper clamping plate contacts the upper sides of the bottle. For plastic bottles of different diameters, the distance between the lowering of the lifting plate and the upper clamping plate is adjusted, thereby adjusting the distance between the upper and lower clamping plates to ensure that the upper clamping plate contacts the top of the plastic bottle, thus enabling the fixing of plastic bottles of different diameters. The limiting assembly limits the horizontal position of the plastic bottle, ensuring that the bottle opening is flush, thereby ensuring the consistency of the cutting assembly's cutting of the bottle opening. It can clamp the same number of plastic bottles as the clamping assembly simultaneously, avoiding frequent clamping operations that waste time and improving production efficiency.

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0029] like Figure 1-5 As shown in the illustration, this application discloses a plastic bottle neck cutting device, including a frame 10, a worktable 11, a lifting plate 21, a clamping assembly 30, a cutting assembly 40, and a limiting assembly 50. The worktable 11 is disposed on the top of the frame 10, and two columns 20 are spaced apart on the top surface of the worktable 11. The lifting plate 21 has vertical through holes on both sides, which are slidably connected to the corresponding columns 20, so that the lifting plate 21 is vertically slidably disposed on the two columns 20. There are several clamping assemblies 30, which are arranged in an array along the line connecting the two columns 20. The clamping assemblies 30 are used to clamp the plastic bottle. The cutting assembly 40 is disposed on the worktable 11 and is used to cut the bottle neck of the plastic bottle. The limiting assembly 50 is disposed on the worktable 11 on the side of the clamping assembly 30 away from the cutting assembly 40, and is used to limit the horizontal position of the plastic bottle.
[0030] Specifically, the clamping assembly 30 includes a mounting plate 31 mounted on the workbench 11. The top surface of the mounting plate 31 has four support columns 32 arranged in a rectangular array. A V-shaped lower clamping plate 33 is mounted on each of the four support columns 32. The bottom surface of the lifting plate 21 has two connecting columns 34. At the lower end of the two connecting columns 34, an inverted V-shaped upper clamping plate 35 is mounted, corresponding to the lower clamping plate 33. The length of the upper clamping plate 35 is shorter than the length of the lower clamping plate 33. A plastic bottle is placed on the lower clamping plate 33 with its opening facing the cutting assembly 40. The lifting plate 21 descends, causing the connecting columns 34 and the upper clamping plate 35 to descend as well, clamping the plastic bottle between the lower clamping plate 33 and the upper clamping plate 35. When the plastic bottle is clamped, the lower clamping plate 33 supports the lower sides of the plastic bottle, while the upper clamping plate 35 contacts the upper sides of the plastic bottle. For plastic bottles of different diameters, the distance of descent of the lifting plate 21 and the upper clamping plate 35 is adjusted, thereby adjusting the distance between the upper clamping plate 35 and the lower clamping plate 33 to ensure that the upper clamping plate 35 contacts the top of the plastic bottle, thus enabling the fixing of plastic bottles of different diameters. The limiting component 50 limits the horizontal position of the plastic bottle to ensure that the bottle mouth is flush, thereby ensuring the consistency of the cutting component 40 in cutting the bottle mouth. It can clamp the same number of plastic bottles as the clamping component 30 at the same time, avoiding frequent clamping operations that waste time and improving production efficiency. The lower clamping plate 33 has clearance grooves 36 on both sides corresponding to the upper clamping plate 35, which avoid the upper clamping plate 35 from getting stuck. Two rubber sheets 37 are symmetrically arranged on the bottom surface of the upper clamping plate 35. The rubber sheets 37, with their high elasticity and friction characteristics, contact the plastic bottle, resulting in a better fixing effect. The bottom surface of the rubber sheet 37 is provided with several rubber protrusions 38, which further enhance the fixing effect on the plastic bottle by increasing the contact area and surface friction.
[0031] During setup, the limiting component 50 includes mounting posts 51 spaced apart on the worktable 11. A fixing block 52 is shared at the upper end of each mounting post 51. A sliding hole is horizontally formed on the fixing block 52 corresponding to the lower clamping plate 33. A sliding rod 53 is slidably mounted within the sliding hole. A limiting plate 54 is positioned at the end of the sliding rod 53 near the lower clamping plate 33, located in the area directly above the lower clamping plate 33. Sliding the sliding rod 53 moves the position of the limiting plate 54. When a plastic bottle is placed, its bottom end contacts the limiting plate 54, thus restricting the horizontal position of the plastic bottle. A connecting rod 55 is shared at the ends of several sliding rods 53 away from the lower clamping plate 33. Pulling the connecting rod 55 causes the several sliding rods 53 to move synchronously, making the adjustment of the limiting plate 54 more convenient. A threaded hole is vertically formed on the fixing block 52, which communicates with one of the sliding holes, and the axis of the threaded hole is perpendicular to the axis of the sliding hole. A threaded rod 56 is screwed inside the threaded hole, and a handle 57 is provided at the upper end of the threaded rod 56. After the position of the limiting plate 54 is adjusted, rotating the handle 57 drives the threaded rod 56 to rotate. When the threaded rod 56 rotates, it moves relative to the sliding rod 53. When the lower end of the threaded rod 56 abuts against the corresponding sliding rod 53, the position of the sliding rod 53 is fixed, thereby fixing the position of the connecting rod 55, and consequently fixing the positions of the other sliding rods 53. Several graduated grooves 58 are spaced along the length of one of the sliding rods 53. By observing the graduated grooves 58 exposed at the opening of the sliding hole on the sliding rod 53, the position of the limiting plate 54 can be determined, making adjustment more convenient.
[0032] In its specific configuration, the cutting assembly 40 includes an electric slide 41 horizontally mounted on the worktable 11, the length of which is perpendicular to the length of the lower clamping plate 33. A mounting base 42 is mounted on the slide of the electric slide 41, with a horizontally arranged circular hole on the mounting base 42. A rotating shaft 43 is rotatably mounted within this hole, its length aligned with that of the lower clamping plate 33. A saw blade 44 is mounted on the end of the rotating shaft 43 closest to the lower clamping plate 33. A drive motor 45 is horizontally mounted on the side of the mounting base 42 furthest from the lower clamping plate 33, and the output shaft of the drive motor 45 is connected to the end of the rotating shaft 43 furthest from the saw blade 44. The drive motor 45 drives the rotating shaft 43 to rotate, thus rotating the saw blade 44. The horizontal movement of the slide of the electric slide 41 moves the mounting base 42, the drive motor 45, and the saw blade 44, cutting several plastic bottles.
[0033] A top plate 22 is provided at the upper end of both columns 20. An electric push rod 23 is vertically installed on the top plate 22. The piston rod of the electric push rod 23 passes downward through the top plate 22 and connects to the top surface of the lifting plate 21. The lifting plate 21 is driven to rise and fall by the electric push rod 23. An inclined frame 12 is provided at the top of the frame 10. The worktable 11 is connected to the top of the inclined frame 12. The side of the worktable 11 near the cutting component 40 is higher than the side near the limiting component 50, so that the lower clamping plate 33 is in an inclined state. During operation, after the operator places the plastic bottle on the lower clamping plate 33, he pushes the plastic bottle towards the limiting plate 54 along the inclined lower clamping plate 33 until the bottom of the plastic bottle contacts the limiting plate 54, completing the pre-positioning step.
[0034] The operating principle of the plastic bottle neck cutting device in this embodiment is as follows: Pulling the connecting rod 55 according to the length of the plastic bottle moves several sliding rods 53, adjusting the position of the limiting plate 54. Then, rotating the handle 57 causes the threaded rod 56 to rotate, and the lower end of the threaded rod 56 contacts the corresponding sliding rod 53 to fix it. Next, the worker places the plastic bottle on the lower clamping plate 33 and pushes it towards the limiting plate 54 along the inclined lower clamping plate 33 until the bottom of the plastic bottle contacts the limiting plate 54. Then, the electric push rod 23 is activated to drive the lifting plate 21 and the upper clamping plate 35 to descend, clamping the plastic bottle between the lower and upper clamping plates 33 and 35. Finally, the drive motor 45 and the electric slide table 41 are activated. The drive motor 45 drives the rotating shaft 43 to rotate, causing the saw blade 44 to rotate. The horizontal movement of the slide block of the electric slide table 41 moves the mounting base 42, the drive motor 45, and the saw blade 44, cutting several plastic bottles.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
