[0002] In the production process of plastic bottles required by the food industry, it is inevitable that burrs will appear at the bottle mouth. Therefore, a plastic bottle mouth burr trimming device is needed to trim the burrs at the bottle mouth. The plastic bottle mouth burr trimming device is a mechanical device specially used to remove burrs, flash or excess plastic generated during the processing of plastic bottle mouths. Its core function is to ensure that the bottle mouth edge is smooth and flat through physical cutting, grinding or hot melting, etc., to meet the process requirements of subsequent filling, sealing or packaging. In the prior art, patent CN219028192U discloses a plastic bottle burr trimming device, which includes a fixed plate, a positioning plate and a movable plate. A connecting rod is fixedly installed on one side surface of the fixed plate, and a positioning plate is fixedly connected to one end of the connecting rod. Mounting seats are threaded on both sides of the positioning plate, and a movable plate is sleeved on the surface of the connecting rod. This plastic bottle burr trimming device has some problems. For example, it can only trim the burrs on the outside of the plastic bottle. At the same time, it requires adjusting the screw mechanism in sequence to achieve the inner support limit of the plastic bottle, which is a cumbersome process and affects the speed of burr trimming at the mouth of the plastic bottle. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a plastic bottle mouth burr trimming device that can simultaneously and quickly trim the burrs inside and outside plastic bottle mouths of different inner diameters, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a plastic bottle neck burr trimming device, including a trimming frame, a protective cover connected to the rear end of the trimming frame by evenly distributed bolts, and an adjustment mechanism; Adjustment mechanism: It includes a sliding mouth, an I-shaped seat, an adjustment plate and auxiliary wheels. The sliding mouth is evenly arranged at the rear end of the trimming frame. The I-shaped seat is slidably connected inside the sliding mouth. The adjustment plate is fixedly connected to the front end of the I-shaped seat. Two auxiliary wheels are rotatably connected to the end of the adjustment plate away from the center of the trimming frame. Two internal trimming scissors are connected to the end of the adjustment plate away from the center of the trimming frame by bolts. The three internal trimming scissors located in the same vertical plane form an internal trimming scissor ring, which can simultaneously and quickly trim the burrs inside and outside the mouth of plastic bottles with different inner diameters.

[0005] Furthermore, the adjustment mechanism also includes inclined plates, inclined platforms, and guide rods. The inclined plates are all fixedly connected to the rear end of the I-shaped base and are located inside the protective cover. The guide rods are uniformly fixedly connected inside the protective cover. An inclined platform is slidably connected between the three guide rods. The three inclined plates are all installed in conjunction with the inclined platform to realize the concentric movement of the adjustment plate.

[0006] Furthermore, the adjustment mechanism also includes a screw and a drive handle. The screw is threaded to the rear end of the protective cover, the front end of the screw is rotatably connected to the center position of the rear surface of the inclined platform, and the rear end of the screw is fixedly connected to the drive handle to provide driving force for the movement of the inclined platform.

[0007] Furthermore, corrugated tubes are provided between the rear surface of the inclined platform and the rear inner wall of the protective cover, as well as between the rear surface of the protective cover and the front surface of the drive handle. The corrugated tubes are all sleeved on the outer surface of the screw to protect the screw.

[0008] Furthermore, the interior of the protective cover is provided with evenly distributed telescopic columns, and each telescopic column has a disc at its telescopic end. The discs are fitted with the side surface of the adjacent inclined plate away from the center of the protective cover.

[0014] 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.

[0015] Please see Figure 1-5 This embodiment provides a technical solution: a plastic bottle neck burr trimming device, including a trimming frame 1, a protective cover 2 connected to the rear end of the trimming frame 1 by evenly distributed bolts, and an adjustment mechanism 3. Adjustment mechanism 3 includes a sliding port 31, an I-shaped base 32, an adjusting plate 33, and auxiliary wheels 34. The sliding ports 31 are evenly distributed at the rear end of the trimming frame 1. I-shaped bases 32 are slidably connected inside each sliding port 31. Adjusting plates 33 are fixedly connected to the front ends of each I-shaped base 32. Two auxiliary wheels 34 are rotatably connected to the end of each adjusting plate 33 furthest from the center of the trimming frame 1. Two internal trimming shears 4 are connected to the end of each adjusting plate 33 furthest from the center of the trimming frame 1 via bolts. Three internal trimming shears 4 located on the same vertical plane form an internal trimming shear ring. Adjustment mechanism 3 also includes an inclined plate 35, an inclined platform 36, and a guide rod 37. The inclined plates 35 are all fixedly connected to the rear end of the I-shaped base 32 and are located inside the protective cover 2. (The guide rod 37 can be installed in the protective cover 2.) A laser rangefinder sensor is installed in the middle of the upper inner wall. The laser rangefinder sensor can be a DT35-B15551. It is bidirectionally electrically connected to an external controller, which operates the sensor. The laser probe of the rangefinder sensor emits laser light onto the laser reflector on the upper surface of the inclined base 35. Based on the speed of light and the time it takes for the laser to reflect back to the probe, the real-time distance 'a' between the upper surface of the inclined base 35 and the upper surface of the protective cover 2 is calculated. The distance 'b' between the upper surface of the protective cover 2 and its longitudinal central axis is also calculated. Let 'c' be the distance between the upper surface of the inclined base 35 and the longitudinal central axis of the protective cover 2. Let c = ba. The laser rangefinder sensor transmits the real-time distance 'a' to the external controller in real time. The signal receiving end of the device, according to the inner diameter of the plastic bottle mouth to be limited, when the distance c between the upper surface of the upper inclined seat 35 and the longitudinal center axis of the protective cover 2 is equal to the inner diameter of the plastic bottle mouth to be limited, stops rotating the drive handle 39 according to the prompt. The guide rods 37 are uniformly fixedly connected inside the protective cover 2. An inclined platform 36 is slidably connected between the three guide rods 37. The three inclined plates 35 are all installed in cooperation with the inclined platform 36. The adjustment mechanism 3 also includes a screw 38 and a drive handle 39. The screw 38 is threaded to the rear end of the protective cover 2. The front end of the screw 38 is rotatably connected to the center position of the rear surface of the inclined platform 36. The rear end of the screw 38 is fixedly connected to the drive handle 39. The rear surface of the inclined platform 36 and the rear inner wall of the protective cover 2 are at a distance of 36 mm. A bellows 10 is provided between the rear surface of the protective cover 2 and the front surface of the drive handle 39. The bellows 10 are all sleeved on the outer surface of the screw 38. (The front end of the bellows 10 inside the protective cover 2 is fixedly connected to the rear surface of the inclined platform 36; the rear end of the bellows 10 inside the protective cover 2 is fixedly connected to the inner rear wall of the protective cover 2; the front end of the bellows 10 outside the protective cover 2 is fixedly connected to the outer rear surface of the protective cover 2; the rear end of the bellows 10 outside the protective cover 2 is rotatably connected to the front end of the drive handle 39 via a rotating ring. The bellows 9 extend or retract as the inclined platform 36 and the drive handle 39 move, providing sealing protection for the screw 38.) The interior of the protective cover 2 is provided with evenly distributed telescopic columns 8.Each telescopic column 8 has a disc at its telescopic end. The discs are fitted onto the surface of the adjacent inclined plate 35 furthest from the center of the protective cover 2. A spring 9 is installed between the disc and the inner wall of the protective cover 2. The spring 9 is sleeved on the outer surface of the adjacent telescopic column 8. (The pin at the end of the spring 9 furthest from the center of the protective cover 2 can be engaged with the inner wall of the protective cover 2 via a snap-fit; the pin at the end of the spring 9 closest to the center of the protective cover 2 is in contact with the corresponding disc, and the disc can be engaged with the telescopic end of the adjacent telescopic column 8. The disc is periodically engaged with the telescopic end of the telescopic column 8.) Next, snap the latch on the pin at the end of spring 9 furthest from the center of protective cover 2, remove spring 9, and replace spring 9 (to prevent aging of spring 9 from affecting the reset effect of adjustment plate 34). According to the required inner diameter of the plastic bottle neck to be trimmed, rotate drive handle 39. The rotation of drive handle 39 drives screw 38 to rotate. Since screw 38 is threaded to the rear end of protective cover 2, screw 38 moves forward during rotation. The forward movement of screw 38 pushes inclined platform 36 forward. Inclined platform 36 slides forward between the three guide rods 37. The inclined arc surface of the inclined plate 36 contacts the inclined surfaces of the three inclined plates 35. As the inclined platform 36 moves, it continuously pushes the three inclined plates 35 away from the center of the protective cover 2. The outward movement of the inclined plates 35 causes the adjacent I-shaped seats 32 to move away from the center of the protective cover 2 within the corresponding sliding openings 31. The outward movement of the I-shaped seats 32 also causes the adjacent adjusting plates 33 to move away from the center of the protective cover 2. The outward movement of the adjusting plates 33 causes the two adjacent auxiliary wheels 34 to move away from the center of the protective cover 2. Furthermore, the inclined plates... During the movement of 35, the outward movement of the inclined plate 35 pushes the adjacent discs, causing the telescopic ends of the adjacent telescopic columns 8 to retract. Simultaneously, the adjacent springs 9 are elastically compressed. The elastic force of the springs 9 reacts to the corresponding inclined plate 35. When the outward pushing force on the inclined plate 35 decreases, the elastic force of the springs 9 provides force for the inward movement of the inclined plate 35, achieving the reset of the inclined plate 35. When the auxiliary wheel 34 reaches the desired position, the drive handle 39 stops rotating, and then the internal trimmers 4 are sequentially installed at the corresponding positions on the adjusting plate 34 using bolts two. The trimming frame 1 is fixedly connected to a mounting frame 5 at its front end. A mounting plate 6 is inserted into the interior of the mounting frame 5. Both the mounting frame 5 and the mounting plate 6 have through holes. Two bolts (three) are threaded onto the upper ends of both the mounting frame 5 and the mounting plate 6. Symmetrically distributed external trimming shears 7 are connected to the front surface of the mounting plate 6 via symmetrically distributed bolts (four). External trimming shears 7 with corresponding inner diameters are installed to the upper and lower ends of the front surface of the mounting plate 6 using bolts (four). Then, the mounting plate 6 is inserted into the interior of the mounting frame 5, and then the mounting plate 6 is connected to the mounting frame 5 using bolts (three). Finally, the bottle neck of the plastic bottle is inserted into the through hole of the mounting frame 5. The external trimming shears 7 and the plastic bottle neck are then connected. The outer side of the bottle mouth contacts the inner wall of the plastic bottle mouth, while the inner trimming scissors 4 contacts the inner wall of the plastic bottle mouth. At the same time, the outer arc surface of the limiting wheel 34 fits against the outer arc surface of the plastic bottle mouth. The rotation of the limiting wheel 34 assists in the movement of the plastic bottle mouth. After the front end of the plastic bottle reaches the rear surface of the trimming frame 1 from front to back, the plastic bottle is pulled out from back to front. During this process, the outer trimming scissors 7 trims the rough edges on the outer side of the plastic bottle mouth, and the inner trimming scissors 4 trims the rough edges on the inner side of the plastic bottle mouth. A single adjustment can simultaneously adjust the position of the three adjusting plates 34 and simultaneously trim the rough edges on the inner and outer sides of the plastic bottle mouth, greatly improving the efficiency of trimming the rough edges of the plastic bottle mouth. The trimming frame 1 has symmetrically distributed mounting bases 11 fixedly connected to both its left and right ends. Each mounting base 11 has symmetrically distributed mounting holes inside. The mounting holes inside the mounting base 11 are stably connected to the threaded holes in the working area by mounting bolts, thereby achieving stable installation of the trimming frame 1, the protective cover 2, and other mechanisms.

[0016] The working principle of the plastic bottle neck trimming device provided by this utility model is as follows: During operation, the operator first uses mounting bolts to stably connect the mounting hole inside the mounting base 11 with the threaded hole in the working area, thereby achieving stable installation of the trimming frame 1, the protective cover 2, and other mechanisms. After stable installation, according to the inner diameter of the plastic bottle neck to be trimmed, the drive handle 39 is rotated. The rotation of the drive handle 39 drives the screw 38 to rotate. Since the screw 38 is threadedly connected to the rear end of the protective cover 2, the screw 38 moves forward during rotation. The forward movement of the screw 38 pushes the inclined platform 36 forward. The inclined platform 36 slides forward between the three guide rods 37. The inclined arc surface of the inclined platform 36 interacts with the three guide rods 37. The inclined surfaces of the inclined plates 35 make contact, and as the inclined table 36 moves, the inclined table 36 continuously pushes the three inclined plates 35 to move away from the center of the protective cover 2. The outward movement of the inclined plates 35 causes the adjacent I-shaped seats 32 to move away from the center of the protective cover 2 inside the corresponding sliding opening 31. The outward movement of the I-shaped seats 32 causes the adjacent adjusting plates 33 to move away from the center of the protective cover 2. The outward movement of the adjusting plates 33 causes the two adjacent auxiliary wheels 34 to move away from the center of the protective cover 2. During the movement of the inclined plates 35, the outward movement of the inclined plates 35 pushes the adjacent discs, thereby causing the telescopic ends of the adjacent telescopic columns 8 to retract. At the same time, the adjacent springs 9... The spring 9 is elastically compressed, and its elastic force reacts to the corresponding inclined plate 35. When the outward pushing force on the inclined plate 35 decreases, the elastic force of the spring 9 provides a force for the inward movement of the inclined plate 35, thus resetting the inclined plate 35. When the auxiliary wheel 34 reaches the desired position, the drive handle 39 stops rotating. Then, the operator installs the inner trimming shears 4 in sequence at the corresponding positions on the adjusting plate 34 using bolt two. Then, the operator installs the outer trimming shears 7 with the corresponding inner diameter to the upper and lower ends of the front surface of the mounting plate 6 using bolt four. Then, the mounting plate 6 is inserted into the interior of the mounting frame 5, and then the mounting plate 6 is connected to the mounting frame 5 using bolt three. Finally, the operator inserts the bottle neck of the plastic bottle into the through-hole of the mounting frame 5. Inside the hole, the outer trimming scissors 7 contact the outer side of the plastic bottle mouth, while the inner trimming scissors 4 contact the inner wall of the plastic bottle mouth. At the same time, the outer arc surface of the limiting wheel 34 fits against the outer arc surface of the plastic bottle mouth. The rotation of the limiting wheel 34 assists in the movement of the plastic bottle mouth. After the front end of the plastic bottle reaches the rear surface of the trimming frame 1 from front to back, the plastic bottle is pulled out from back to front. During this process, the outer trimming scissors 7 trims the rough edges on the outer side of the plastic bottle mouth, and the inner trimming scissors 4 trims the rough edges on the inner side of the plastic bottle mouth. A single adjustment can simultaneously adjust the position of the three adjusting plates 34 and simultaneously trim the rough edges on the inner and outer sides of the plastic bottle mouth, greatly improving the efficiency of trimming the rough edges of the plastic bottle mouth.

Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
