Description
Technical Field
[0001] This utility model relates to the field of bucket lifting technology, and in particular to a bucket lifting device for composite plastic bottle cap production line. Background Technology
[0002] Bottled water is a common beverage in daily life and industrial production, and the convenience and safety of its handling tools (bottle carriers) directly affect the user experience. In existing technology, bottle carriers typically include a handle, a connecting rod, and a ring-shaped buckle, which is secured by a spring in the ring-shaped buckle engaging with a retaining ring on the top of the water bottle.
[0003] Traditional bucket lifters typically have a single-piece ring-shaped buckle that requires cutting with scissors or other tools to disassemble. This is especially problematic in situations where tools are unavailable, such as at home or on a production line, where users may have to forcefully tear the buckle, potentially causing hand injuries or the bucket to tip over, posing a safety hazard. Some improved solutions use tear-out openings and grooves to allow for manual disassembly, but these openings are only temporarily secured with weak connecting pieces or thin wires. When lifting an 18kg water bottle, uneven force or impact can easily cause the tear-out opening to tear, leading to premature failure of the bucket lifter and increasing handling risks. Existing tear-out bucket lifters have a one-time breakage design; once the groove is torn, the ring-shaped buckle is completely destroyed, rendering the bucket lifter unusable. This not only increases user procurement costs but also creates environmental pressure due to the accumulation of plastic waste, a problem that is particularly pronounced in high-frequency usage scenarios such as composite plastic bottle cap production lines.
[0004] Therefore, this utility model aims to solve the problems of existing bucket lifters being "difficult to disassemble, prone to accidental disassembly, and not environmentally friendly," and to provide a bucket lifter for composite plastic bottle cap production lines that takes into account safety, economy, and convenience. Utility Model Content
[0005] The main technical problem solved by this utility model is to provide a bucket lifting device for a composite plastic bottle cap production line, thereby solving one or more of the above-mentioned prior art problems.
[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a bucket lifting device for a composite plastic bottle cap production line, including a handle, the two ends of which are connected to an annular buckle by a connecting rod. The annular buckle has several spring pieces inside the ring, and there is a gap between adjacent spring pieces. The innovation is that a basic frame is provided at the connection between the annular buckle and the connecting rod. A break piece is detachably connected to the basic frame. The break piece is provided with a tearing opening and a groove extending inward to the annular buckle. The break piece is also provided with a locking component to prevent accidental disassembly.
[0007] In one embodiment, the locking assembly includes an L-shaped locking groove and a slidable locking block disposed on the fracture piece. The fracture piece is provided with a T-shaped slot, and the bottom of the locking block is provided with an elastic buckle adapted to the T-shaped slot. The locking block is connected to the fracture piece by engaging the buckle with the slot. In its natural state, the locking block is engaged in the L-shaped locking groove to lock the tear opening.
[0008] In one embodiment, the elastic buckle is a barb-shaped structure with an outwardly inclined guide slope at its end. The inner wall of the T-shaped groove is provided with a limiting boss that matches the barb. When the locking block is pressed, the elastic buckle undergoes elastic deformation, the barb disengages from the limiting boss, and the locking block slides along the T-shaped groove to exit the L-shaped locking groove.
[0009] In one embodiment, an annular groove is provided on the inner side of the base frame, and the edge of the fracture piece is provided with a flange that is adapted to the annular groove. The fracture piece is detachably connected by engaging the flange into the annular groove.
[0010] In one embodiment, the grooves on the fracture fragment are arranged in a cross shape, and the depth of the grooves is 2 / 3 of the thickness of the fracture fragment.
[0011] In one embodiment, the number of spring pieces is 14-18, and the spacing between adjacent spring pieces is 2-3 mm.
[0012] In one embodiment, the flange thickness is 1.5-2 mm, and the depth of the annular groove is adapted to the flange thickness.
[0013] The beneficial effects of this utility model are: by optimizing the locking components, detachable structure and detailed parameters, this technical solution significantly improves the practicality, safety and economy of the bucket lifter, and is especially suitable for the efficient handling needs of bottled water in composite plastic bottle cap production lines.

[0019] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0020] like Figures 1 to 4 As shown, this utility model embodiment includes: a bucket lifter for a composite plastic bottle cap production line, used to solve the problems of traditional bucket lifters being difficult to disassemble, prone to accidental disassembly, and unable to be reused; its structure includes a handle 102, a connecting rod, a ring buckle 100, a spring 202, a basic frame, a replaceable break piece 200, and a locking assembly. The specific structure and connection relationship of each component are as follows:
[0021] Handle 102: Made of PP material through one-piece injection molding, with an overall arc-shaped structure. The inner side has a wavy widened part (30mm wide and 5mm thick). The arc of the area that fits the palm is R35mm, which is suitable for the size of an adult's palm and reduces the pressure when lifting.
[0022] Connecting rod: It is a cylindrical rod with a diameter of 8mm. Both ends are connected to the handle part 102 and the ring buckle part 100 through arc transitions. The inner side of the connection is provided with a U-shaped reinforcing rib (4mm high and 2mm thick) to improve the connection strength between the connecting rod and the buckle part and prevent breakage when lifting.
[0023] The ring-shaped buckle part 100 has a circular structure (inner diameter 55mm, outer diameter 65mm), with 16 spring pieces 202 evenly distributed inside the ring, and the distance between adjacent spring pieces 202 is 2.5mm.
[0024] Spring 202: It adopts a trapezoidal structure (top base 8mm, bottom base 12mm, height 15mm). The wide side is integrally connected to the inner wall of the ring buckle part 100 by injection molding. The lower side is provided with a first reinforcing rib (the cross section is triangular and the height is 2mm) to improve the load-bearing capacity of the spring 202 (a single spring 202 can withstand a tensile force of ≥2kg) and prevent the spring 202 from deforming and failing when lifting the bucket.
[0025] Basic frame: Located at the connection between the annular buckle 100 and the connecting rod, it has an annular frame structure (10mm wide and 3mm thick), with an annular groove 101 (1.8mm deep and 2mm wide) on the inner side for installing the broken piece 200.
[0026] Fracture fragment 200: Made of modified PP material (1mm thick), with a flange 201 (1.8mm thick, 2mm wide) on the edge that matches the annular groove 101. The flange 201 and the groove are interlocked for detachable connection. The fracture fragment 200 has a tear opening 400 (20mm long, 3mm wide) in the middle. The tear opening 400 extends inward to form a cross-shaped groove 401 (cut depth 0.67mm, which is 2 / 3 of the thickness of the fracture fragment 200), ensuring that the fracture breaks along the groove 401 during tearing and avoiding fragments from flying.
[0027] Locking components include an L-shaped lock groove 402, a lock block 500, a T-shaped slot 403, and a spring-loaded buckle 502.
[0028] L-shaped locking groove 402: It is formed on the surface of the broken piece 200, with a transverse section length of 15mm and a longitudinal section depth of 8mm, and is used for locking the locking block 500.
[0029] Lock block 500: Made of ABS engineering plastic, it has a rectangular structure (20mm long × 10mm wide × 5mm high) and a T-shaped slider (4mm wide and 2mm high) at the bottom, which slides in conjunction with the T-shaped slot 403.
[0030] T-shaped slot 403: It is formed on the fracture piece 200, with a length of 30mm and a width of 4mm. The inner wall is provided with a limiting boss (height of 1mm), which cooperates with the elastic buckle 502 to realize the positioning of the locking block 500.
[0031] Elastic buckle 502: It has a barbed structure (made of modified PP, with an elastic deformation range of 3mm) and a guide slope at the end (inclination angle of 30°). When the end of the barb engages with the limiting boss, the locking block 500 is engaged in the longitudinal section of the L-shaped locking groove 402, locking the tear opening 400. When the locking block 500 is pressed, the guide slope is pressed, causing the elastic buckle 502 to deform inward, the barb disengages from the limiting boss, and the locking block 500 slides along the T-shaped groove 403 to the transverse section of the L-shaped locking groove 402, releasing the tear opening 400.
[0032] The working principle of the locking component is as follows: In its natural state, the locking block 500 engages with the limiting boss of the T-shaped slot 403 through the elastic buckle 502, and remains in the longitudinal section of the L-shaped locking slot 402, locking the tear opening 400 to prevent accidental tearing; when disassembling, manually press the locking block 500, the elastic buckle 502 deforms along the guide slope, the barb disengages from the limiting boss, the locking block 500 slides along the T-shaped slot 403 to the transverse section, releasing the tear opening 400, and the broken piece 200 can be torn off along the groove 401.
[0033] The advantages of locking components are:
[0034] The springless design avoids accidental locking caused by spring fatigue failure, resulting in a more stable structure.
[0035] The mechanical locking of the barb and the limiting boss provides strong load-bearing capacity (can withstand ≥50N of pulling force, meeting the needs of bottled water lifting);
[0036] The guide ramp design makes unlocking easier and can be done manually without tools.
[0037] The base frame and the fracture piece 200 are detachable and reusable. The working principle is as follows: the fracture piece 200 is press-fitted with the annular groove 101 of the base frame through the flange 201. During installation, the flange 201 is aligned with the groove and pressed to fix it. After tearing and breaking, the fracture piece 200 can be rotated along the groove direction to disengage the flange 201 from the groove. After replacing the fracture piece 200, it can be reused.
[0038] The advantages of the basic frame and fracture fragment 200 are:
[0039] The cost of a single chip is ≤0.1 yuan, and users can replace them in batches, reducing the cost of use;
[0040] Avoid complete disposal, reduce plastic waste, and meet environmental protection requirements;
[0041] The interference fit connection has high strength (disassembly force ≥30N), ensuring that the broken piece 200 does not fall off when lifted.
[0042] The load-bearing capacity and stability of the spring piece 202 and the reinforcing rib are achieved through the following working principle: the wide side of the trapezoidal spring piece 202 is connected to the annular buckle part 100, and the narrow side is inclined inward (inclination angle 15°). After the water bottle buckle is inserted, the spring piece 202 is compressed and undergoes elastic deformation, which fixes the water bottle through friction. The first reinforcing rib and the U-shaped reinforcing rib disperse the stress and prevent the spring piece 202 and the connecting rod from breaking.
[0043] The advantages of shrapnel 202 and reinforcing ribs are:
[0044] The 16 spring pieces 202 are evenly distributed, with each spring piece 202 bearing a load of ≤1.25kg and a total load capacity of ≥20kg (meeting the requirements of 18L bottled water);
[0045] The trapezoidal structure and reinforcing rib design ensure that the deformation recovery rate of the 202 spring is ≥95% and its service life is ≥50 lifting cycles.
[0046] The wavy, widened section reduces hand pressure (≤20kPa) and improves lifting comfort.
[0047] The working principle of this technical solution is as follows:
[0048] Installation: Insert the ring buckle 100 into the top retaining ring of the bottled water. After the spring piece 202 is deformed by pressure, it fits against the inner wall of the retaining ring and fixes the bottle lifter by friction. At this time, the locking block 500 of the locking component is in the longitudinal section of the L-shaped locking groove 402, locking the tear opening 400.
[0049] Lifting: The wavy widened part of the handle 102 fits the palm, the connecting rod disperses stress through the U-shaped reinforcing rib, and the spring 202 bears the weight of the bucket to ensure structural stability.
[0050] Disassembly: Press the locking block 500, the elastic buckle 502 disengages from the limiting boss, the locking block 500 slides to the transverse section of the L-shaped locking groove 402, tear the broken piece 200 along the tear opening 400, the groove 401 breaks in a direction, the annular buckle part 100 is released, and the bucket lifter is removed.
[0051] Reusable: Replace with a new broken piece 200, and fix it by engaging the flange 201 with the annular groove 101, and it can be installed and used again.
[0052] The advantages of this technical solution are:
[0053] Anti-accidental disassembly safety design: The mechanical locking structure of the locking components prevents accidental tearing, solving the problem of easy accidental disassembly of traditional bucket lifters and improving the safety of use.
[0054] Reusability and environmental friendliness: The replaceable 200-piece design allows the bucket body to be reused ≥10 times, reducing plastic waste by more than 80%.
[0055] Simplified structure and low cost: The spring design is eliminated and a snap-slot mechanism is used, which reduces the number of parts by 30%, improves assembly efficiency by 50%, and reduces production costs by 20%.
[0056] Stable load-bearing capacity and comfort: The combination of spring 202 and reinforcing rib has strong load-bearing capacity, and the wavy widened part improves hand comfort, making it suitable for high-frequency handling scenarios on the production line.
[0057] This embodiment significantly improves the practicality, safety, and economy of the bucket lifter by optimizing the locking components, detachable structure, and detailed parameters, and is especially suitable for the efficient handling needs of bottled water in composite plastic bottle cap production lines.
