Description

Technical Field

[0001] This utility model relates to the field of food processing technology, and in particular to a variable diameter barrel positioning device and a cylinder lifting machine. Background Technology

[0002] In food processing, raw materials are placed in buckets and transferred to a lifting machine via a bucket trolley. The lifting machine then lifts and reverses the bucket to transfer the raw materials to the next process. For example, existing patent CN202223150216.5 describes a novel cake lifting device. This device uses three relatively fixed slots, allowing it to accommodate buckets of only one diameter. However, food processing involves buckets of varying volumes and diameters, resulting in poor versatility of existing lifting devices. Furthermore, during the process of moving the bucket to the lifting device via the trolley, the bucket's side ears collide with the slots, causing damage after a period of use and posing a safety hazard. While existing lifting devices use clamping mechanisms to hold buckets of different diameters, these mechanisms require a clamping drive assembly, leading to complex structures, susceptibility to damage, and high maintenance costs. Additionally, the added steps of clamping and releasing the bucket reduce raw material transfer efficiency.

[0003] Therefore, a variable diameter barrel positioning device and a cylinder lifting machine are needed to solve the above problems. Utility Model Content

[0004] This utility model proposes a variable diameter bucket positioning device and a cylinder lifting machine, which realizes the positioning of buckets of various diameters. At the same time, it is used in conjunction with a bucket trolley positioning device to guide and position bucket trolleys of various specifications, thereby achieving dual positioning of buckets of various diameters. This enables the cylinder lifting machine to quickly and accurately adapt to buckets of various diameters, improving the versatility of the cylinder lifting machine.

[0005] The first technical solution of this utility model is implemented as follows: A variable diameter hopper positioning device includes a hopper positioning switching device and a hopper trolley positioning device, which are installed sequentially from top to bottom on the frame along the Z-axis. The hopper positioning and switching device includes a positioning frame slidably mounted on the frame along the Z-axis. The positioning frame has an opening. A hopper positioning switcher is provided on both sides and at the end of the positioning frame. Each hopper positioning switcher includes a rotating seat rotatably mounted on the positioning frame. At least two guide slides are fixedly mounted on the rotating seat. An included angle is provided between two adjacent guide slides. An eccentric distance is formed between the center of the circle formed by the rotation axis of the rotating seat and the center of the circle formed by the common tangency of the guide slides. Each guide slide is adapted to the side lug of the corresponding hopper. A first locking component is provided between each rotating seat and the positioning frame. The material hopper trolley positioning device includes two adjustable guide positioners. Each adjustable guide positioner includes a support frame fixedly installed on the frame. The support frame is provided with a guide member and a positioning arm in sequence along the Y-axis direction. The guide members are constrained and installed on the support frame along the X-axis direction. The positioning arms are hinged to the support frame. A second locking component is provided between the support frame and the guide member, and between the positioning arm and the support frame.

[0006] As a preferred technical solution, each of the rotating seats is fixedly installed with two horizontally arranged guide slides, the rotating seats are horizontally arranged, and the included angle between the two guide slides is 90 degrees.

[0007] As a preferred technical solution, the sides of each of the guide slides are open, and the openings of the guide slides are not on the same horizontal plane.

[0008] As a preferred technical solution, each of the first locking components includes a locking frame fixedly installed on the positioning frame, a locking pin is installed on the locking frame, and the rotating seat is provided with a plurality of positioning pin holes adapted to the locking pin, wherein the locking pin is an indexing pin.

[0009] As a preferred technical solution, the guide member is provided with a plurality of limiting straight elongated holes, the positioning arm is provided with a limiting arc-shaped elongated hole, and a second locking component is provided in each of the limiting arc-shaped elongated holes and each of the limiting straight elongated holes.

[0010] As a preferred technical solution, the guide includes a horizontal sliding plate, on which a vertical guide plate extending along the Y-axis is fixedly mounted. The end of the vertical guide plate is provided with a bent portion, and the limiting straight elongated hole is formed on the horizontal sliding plate.

[0011] As a preferred technical solution, each of the second locking components includes an engaging bolt, an engaging sleeve, and a locking bolt. The engaging sleeve has a communicating engaging cavity and an mounting cavity. The engaging bolt includes an engaging screw head and a first screw. The engaging screw head engages with the inner wall of the engaging cavity. The locking bolt includes a locking screw head and a second screw. The locking bolt is disposed in the mounting cavity. The second screw extends into the engaging cavity and is threaded together with the engaging screw head. A reset element is provided between the mounting cavity and the locking screw head. A handle is provided on the outer wall of the engaging sleeve.

[0012] As a preferred technical solution, each of the guide slides has a guide opening at one end and a baffle at the other end. The bottom inner wall of the guide slide is provided with a limiting protrusion, which is located at the guide opening.

[0013] The second technical solution of this utility model is implemented as follows: This technical solution is basically the same as the first technical solution, except that baffles are provided at both ends of each of the guide slides.

[0014] The third technical solution of this utility model is implemented as follows: The cylinder lifting machine includes a frame, on which a lifting frame is slidably mounted vertically. The lifting frame is connected to a lifting frame drive mechanism. A positioning frame is hinged to the lifting frame. A material barrel positioning switch as described in the first technical solution is provided on both sides of the positioning frame. A material barrel positioning switch as described in the first technical solution is provided at the end of the positioning frame. The two adjustable guide positioning switches are adapted to the material barrel trolley. A pair of guide wheels arranged along the X-axis are rotatably mounted on the positioning frame. A pair of unloading guide rails adapted to the two guide wheels are fixed on the frame.

[0015] By adopting the above technical solution, the beneficial effects of this utility model are as follows: Because the variable diameter bucket positioning device includes a bucket positioning switching device and a bucket trolley positioning device, the bucket positioning switching device includes three rotating seats. Before the rotating seats rotate, the three rotating seats form a first circle that is tangent to each other, and after the rotating seats rotate, the three rotating seats form a second circle that is tangent to each other. The diameters of the first circle and the second circle are different. Therefore, the bucket positioning switching device achieves rapid positioning of buckets of different diameters by rotating the rotating seats. At the same time, the bucket trolley positioning device achieves rapid guidance and positioning of the base of buckets of various diameters by adjusting the linear guide and rotating the adjusting positioning arm. This ensures that the side ears on the outer wall of the bucket are aligned with the guide slide, avoiding the impact of the side ears on the guide slide due to the bucket being tilted. In summary, this utility model provides dual positioning of the bucket by setting up a bucket positioning switching device and a bucket trolley positioning device, thereby enabling the cylinder lifting machine to quickly and accurately adapt to buckets of various diameters and improving the versatility of the cylinder lifting machine.

[0016] The limiting ribs can limit the movement of the material bucket by using the side lugs on the bucket, preventing the bucket from separating from the guide slide when the lifting machine moves the bucket vertically, thus improving the safety of the lifting machine.
