Description

Technical Field

[0001] This utility model relates to the field of mahjong machine technology, specifically to a multi-station automatic cutting device for plastic frames of mahjong machines. Background Technology

[0002] A mahjong machine is an automated electronic device specifically designed for the shuffling, arranging, and dealing of mahjong tiles. Its core function is to replace traditional manual operation with a built-in motor, transmission device, and program control system, randomly stirring the mahjong tiles, arranging them evenly, and pushing them to the player's position. Modern mahjong machines are typically equipped with intelligent recognition technology, support multiple mahjong rules, and allow adjustment of the number of tiles, speed, and gameplay modes. Some high-end models also integrate voice prompts, self-diagnosis of faults, and anti-cheating designs. Mahjong machines are widely used in home entertainment, card rooms, and other scenarios, significantly improving game efficiency and fairness, and have become an important tool in modern mahjong culture.

[0003] The frame of a mahjong machine is often cut into four identical frames by wire cutting and then spliced ​​together. However, wire cutting can only cut one frame at a time, which greatly reduces cutting efficiency. Based on this, this utility model designs a multi-station automatic cutting device for the plastic frame of a mahjong machine to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-station automatic cutting device for plastic frames of mahjong machines, so as to solve the problem mentioned in the background art that wire cutting can often only cut one frame, which greatly reduces the cutting efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-station automatic cutting device for plastic frames of mahjong machines, comprising a wire cutting machine body, a cutting line inside the wire cutting machine body, a moving device inside the wire cutting machine body, a moving plate inside the wire cutting machine body, the moving plate being fixedly connected to the moving device of the wire cutting machine body, five limiting plates fixed at the front end of the moving plate, a fixing plate between every two adjacent limiting plates, an adjusting plate fixed on the side of each fixing plate near the rear end of the moving plate, two sliding rods symmetrically fixed at the rear end of the moving plate, the adjusting plate being slidably connected to the sliding rods, a first lead screw rotatably connected to the middle of the rear end of the moving plate, the first lead screw being threadedly connected to the uppermost adjusting plate, the rear end of each adjusting plate being fixedly connected to other adjusting plates through a connecting device, a servo motor fixed on the top surface of the wire cutting machine body, a second helical gear fixed at the output end of the servo motor, a first helical gear fixed on the top surface of the first lead screw, and the first helical gear meshing with the second helical gear.

[0006] Preferably, the connecting device includes a second lead screw, and each of the adjusting plates has a limiting groove at its rear end that matches the shape of the second lead screw. The second lead screw is detachably disposed inside the limiting groove at the rear end of the adjusting plate. Each of the second lead screws is threaded with a plurality of limiting nuts, and the top and bottom surfaces of each adjusting plate are fixedly connected to the second lead screw with the limiting nuts.

[0007] Preferably, a shock-absorbing pad is fixed to the bottom end of the fixing plate, and the shock-absorbing pad is made of non-slip rubber.

[0008] Preferably, the other three adjustment plates below the interior of the movable plate are all provided with through holes in their middle parts, and the radius of the through holes is larger than the radius of the first lead screw.

[0009] Preferably, the shape of the fixing plate is the same as the shape of the limiting plate, and the shape of the limiting plate is the same as the shape of the finished frame.

[0010] Preferably, a connecting plate is fixed to the rear end of the moving plate, and the connecting plate is detachably fixed to the moving device of the wire cutting machine body by bolts.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] (1) In this utility model, the main body of the online cutting machine controls the moving end to fix the moving plate through the connecting plate, and the four sides are placed between the two limiting plates respectively. Then, the servo motor drives the first lead screw to rotate, so that the first lead screw drives the adjusting plate to limit and fix the side. This allows the four sides to be cut by the cutting line, which solves the problem mentioned in the background art that the wire cutting can often only cut one side, which greatly reduces the cutting efficiency.

[0013] (2) The four adjusting plates are connected together by the second lead screw, so that when the first lead screw moves the uppermost adjusting plate, the other adjusting plates move at the same time. This avoids errors caused by multiple adjusting plates being threaded on the first lead screw, which affect the movement accuracy between the adjusting plates. At the same time, a shock-absorbing pad is attached to the bottom of the fixed plate. While the shock-absorbing pad fixes the frame, its soft material can also compensate for the accuracy error between the first lead screw and the adjusting plate, thus avoiding the situation where the fixed plate cannot fix the frame.
