DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail with reference to the accompanying drawings. It is hereby stated that the directional words such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the utility model are only based on the accompanying drawings of the utility model, and are not specific limitations of the utility model.

[0020] A drum-paper pressing device for a linear external magnetic speaker assembly machine, such as Figure 1 , Figure 2 and Figure 3 As shown, it includes a base 1, a mold 2, a fixing frame 3, a flip plate 4, a cylinder 5 and a pressing plate 6. The base 1 is narrow at the top and wide at the bottom, and has strong supporting stability. A mounting groove is opened in the middle of the base 1, and the mold 2 is magnetically attracted in the mounting groove in the middle of the base 1. The upper left side of the base 1 is connected to the fixing frame 3, and the upper part of the fixing frame 3 is rotatably connected to the flip plate 4 for flipping and storing. The upper right side of the flip plate 4 is connected to the cylinder 5 for driving the pressing. The telescopic rod of the cylinder 5 passes through the flip plate 4 and is connected to the pressing plate 6 for pressing down. The lower edge of the pressing plate 6 is connected to an anti- The scraping surface is avoided to cause unnecessary wear to the drum paper, and a limiting mechanism 7 is also included. The limiting mechanism 7 includes a limiting member 71, a dual-axis motor 72 and a screw rod 73. The dual-axis motor 72 is connected to the right side of the middle of the fixed frame 3, and the output shafts of the dual-axis motor 72 are connected to the screw rods 73. The screw rods 73 are threadedly connected with limiting members 71 for limiting the storage of the cylinder 5. The left part of the limiting member 71 is arc-shaped, which is convenient for clamping and limiting the upper part of the cylinder 5. The limiting member 71 is slidably connected to a part adjacent to the fixed frame 3.

[0021] This device can be used when pressing drum paper. It should be noted that first, the dual-axis motor 72 is started, so that the output shafts of the dual-axis motor 72 drive the adjacent screw rods 73 to slide to one side along the fixed frame 3, so that the limiting members 71 are all out of the limiting clamping state of the cylinder 5, and then the mold 2 is placed in the placement groove in the middle of the base 1, so that the mold 2 and the base 1 are magnetically fixed, and at the same time, the flip plate 4 is used to drive the cylinder 5 to rotate to the right, so that the telescopic rod of the cylinder 5 drives the pressing plate 6 to rotate to the upper side of the mold 2, and then the two pieces of drum paper are stacked and calibrated and placed on the mold 2, and the cylinder 5 is started at the same time, so that the telescopic rod of the cylinder 5 drives the adjacent pressing plate 6 to move downward, so that the pressing plate 6 presses the drum paper stacked on the mold 2, and after pressing is completed, the cylinder 5 is closed, so that the telescopic rod of the cylinder 5 drives the pressing plate 6 to move upward The cylinder 5 is then moved to the left by the flip plate 4 to be reset, thereby the cylinder 5 drives the pressing plate 6 to rotate to the left and reset, and then the double-axis motor 72 is turned off, so that the output shafts of the double-axis motor 72 drive the screw rod 73 to rotate in the opposite direction, thereby the screw rod 73 drives the adjacent limiting members 71 to clamp and limit the upper part of the cylinder 5, thereby preventing the flip plate 4 from shaking randomly during the transportation and movement of the base 1, thereby causing damage to the cylinder 5. In summary, through the cooperation between the double-axis motor 72 and the screw rod 73, the screw rod 73 drives the adjacent limiting members 71 to limit and clamp the upper part of the cylinder 5, thereby preventing the flip plate 4 from shaking randomly during the transportation and movement of the base 1, thereby causing damage to the cylinder 5, thereby improving the stability of the cylinder 5 during the movement and transportation of the base 1.

[0022] like Figure 1 and Figure 4 As shown, a protective mechanism 8 is also included, and the protective mechanism 8 includes a connecting member 81, a protective cover 82 and a handle 83. The connecting member 81 is rotatably connected to the right side of the upper part of the base 1, and a protective cover 82 for covering and protecting the upper part of the base 1 is connected to the right side of the connecting member 81. Handles 83 for assisting in rotating the protective cover 82 are connected to the front and rear sides of the protective cover 82, and anti-slip grooves are connected to the handles 83.

[0023] It should be noted that when using the base 1, the handle 83 is used to drive the protective cover 82 to rotate to the right through the connecting piece 81 to open, so that the protective cover 82 no longer covers and protects the upper part of the base 1, and the mold 2 can be used to place and press the drum paper. After the base 1 is used, the handle 83 is used to drive the protective cover 82 to rotate to the left through the connecting piece 81 to close and reset, so that the protective cover 82 resumes covering and protecting the upper part of the base 1. At this time, the middle part of the right part of the protective cover 82 is engaged with the fixed frame 3, and the base 1 can be moved and transported. In summary, through the cooperation between the connecting piece 81 and the protective cover 82, the protective cover 82 covers and protects the upper part of the base 1, thereby improving the safety of the base 1 during the placement and transportation process.
