Figure 1 As shown, the linear capping machine includes: a frame 2, a machine door 3, a conveyor line bracket 4, a conveyor line 5, bottles to be capped 6, a synchronous belt 9, a machine head 10, a power motor 11, a first lifting screw rod 12, a second lifting screw rod 13 and a lifting screw rod 14, wherein:

[0030] The machine door 3 is hung on the frame 2, the conveyor line 5 is connected to the frame 2 with bolts through the conveyor line bracket 4, the conveyor line 5 and the conveyor line bracket 4 are fixed by bolts, the conveyor line 5 and the frame 2 are connected as a whole, the first bottle to be capped 601 and its first bottle cap 7, the second bottle to be capped 602 and its second bottle cap 8 are placed on the conveyor line 5, the machine head 10 is connected to the top of the frame 2 through the first lifting screw rod 12, the second lifting screw rod 13 and the thread, the overall height of the machine head 10 is adjusted through the first lifting screw rod 12 and the second lifting screw rod 13 through the lifting screw rod 14 to adapt to bottles of different heights, the synchronous belt 9 is fixed to the machine head 10, and the power motor 11 is fixed to the machine head 10 by bolts to drive the synchronous belt 9 to move.

[0031] Among them, reference Figure 1 As shown, the bottles to be capped on the conveyor line 5 of the present application are not limited to the first bottle to be capped 601 and the bottle to be capped 602 shown. Figure 1 This is just an example, there is no limit to the number of bottles to be capped.

[0032] Optionally, refer to Figure 1As shown, the linear capping machine also includes: a machine foot 1, which has an external thread connected and fixed to the frame 2, and the machine foot thread can be adjusted to lift the overall height of the device.

[0033] Optionally, Figure 2 This is a side view of the linear capping machine. Figure 3 for Figure 2 Schematic diagram of cross section CC, reference Figure 3 and Figure 4 As shown, the machine head 10 includes: a synchronous wheel 101, a spring sleeve 102, a connecting pin 103 and a spring 104, wherein

[0034] The synchronous belt 9 is fixed on the synchronous wheel 101, and the spring sleeve 102 is fixed on the machine head 10 and cannot rotate. The spring 104 is placed in the spring sleeve 102, with the upper end against the first lifting screw rod 12 and the lower end against the step inside the spring sleeve 102. An adjustment hole is opened at the lower end of the first lifting screw rod 12, and the connecting pin 103 passes through the adjustment hole of the first lifting screw rod 12 and is fixed on the spring sleeve 103, so that the first lifting screw rod 12 can move up and down but cannot rotate.

[0035] Specifically, the function of spring 104 is: when pressing the lid, it is necessary to ensure that the lid is pressed tightly against the bottle mouth of the bottle to be capped, and to ensure that the lid or the bottle is not damaged, so the spring is installed in the spring sleeve 102 here, the upper end face of the spring 104 presses against the lifting screw rod 14, and the lower section presses on the step in the spring sleeve 102. The part of the first lifting screw rod 12 in the spring sleeve 102 has a strip opening, which is connected to the spring sleeve 102 through a connecting pin 103. When the synchronous belt 9 presses the bottle cap downward, if the upward force of the bottle cap is greater than the force of the spring, the spring sleeve will overcome the pre-pressure of the spring and move upward until the connecting pin 103 rigidly blocks the lower end face of the strip opening. The upward movement stroke of the strip hole designed here is greater than the stroke of the bottle cap being pressed into place, so the connecting pin will not block the lower end face of the strip opening, and the spring always acts on the flexible pressing bottle cap.

[0036] Optionally, refer to Figure 1 As shown, the linear capping machine also includes: a first transmission chain 20 and a transmission sprocket 21 arranged on the first transmission chain 20, wherein the power motor 11 drives the transmission sprocket 21, the transmission sprocket 21 drives the synchronous wheel 101 to rotate, and the synchronous belt 9 moves under the drive of the synchronous wheel 101.

[0037] Optionally, refer to Figure 5 As shown, the linear capping machine also includes: a lifting driving wheel 15, a first lifting passive wheel 16, a second transmission chain 17, a second lifting passive wheel 18, and a lifting motor 19, wherein

[0038] The first lifting passive wheel 16 and the second lifting passive wheel 18 are respectively fixed to the first lifting screw rod 12 and the second lifting screw rod 13 through screw threads. The first lifting screw rod 12 and the second lifting screw rod 13 cannot rotate under the fixation of the connecting shaft of the machine head 10. Under the rotation of the first lifting passive wheel 16 and the second lifting passive wheel 18, the first lifting screw rod 12 and the second lifting screw rod 13 can only rise or fall. The lifting active wheel 15 is fixed to the lifting motor 19 through a key groove. The lifting active wheel 15, the first lifting passive wheel 16 and the second lifting passive wheel 18 are connected through the second transmission chain 17. When the lifting motor 19 is running, the lifting active wheel 15 rotates and drives the first lifting passive wheel 16 and the second lifting passive wheel 18 to rotate through the second transmission chain 17. The first lifting screw rod 12 and the second lifting screw rod 13 are driven by the first lifting passive wheel 16 and the second lifting passive wheel 18 to rise or fall through the lifting screw rod 14.

[0039] Specifically, lifting adjustment: bottles are of different heights, and the height of the machine head 10 and the conveyor belt on the conveyor line 5 is adjusted by the first lifting screw 12 and the second lifting screw 13 to match bottles of different heights. When the lifting motor 19 is running, it drives the lifting driving wheel 15 to rotate, and the lifting driving wheel 15 is connected to the first lifting passive wheel 16 and the second lifting passive wheel 18 through the second transmission chain 17. When the lifting driving wheel 15 rotates, the lifting passive wheel will also rotate, and the lifting screw seat 14 drives the lifting screw to rise or fall, so as to adjust the height of the machine head 10 and the conveyor belt.

[0040] Optionally, refer to Figure 3 and Figure 6 As shown, the lifting screw 14 includes: a lifting seat 141, a first bearing 142, a lifting nut sleeve 143, and a second bearing 144, wherein

[0041] The lifting seat 141 is fixed to the frame 2 by bolts, the second lifting passive wheel 18 is fixed to the lifting nut sleeve 143 by a keyway, the lifting nut sleeve 143 is fixed to the lifting seat 141 by a first bearing 142 and a second bearing 144. Under the rotation of the second lifting passive wheel 18, the lifting nut sleeve 143 will rotate, and a nut matching the lifting screw rod 14 is embedded in the lifting nut sleeve 143. Driven by the rotation of the lifting nut sleeve 143, the lifting screw rod 14 can move up and down.

[0042] Specifically, the lifting structure of the lifting screw: the lifting nut sleeve 143 is fixed on the lifting seat 141 through the first bearing 142 and the second bearing 144. The lifting nut sleeve 143 has a thread inside that cooperates with the lifting screw 14. When the lifting passive wheel 18 rotates, it drives the lifting nut sleeve 143 to rotate. Since the lifting screw 14 is fixed on the spring sleeve 102 by the connecting pin 103 and cannot rotate, the rotation of the lifting nut sleeve drives the lifting screw to rise and fall.

[0043] Optionally, the bottom surface of the synchronous belt 9 is higher on the left and lower on the right, and the distance between the bottom surface of the synchronous belt 9 and the conveyor line 5 becomes smaller as it moves to the right.

[0044] In addition, reference Figure 7 As shown, the working principle of the linear capping machine of the present application is as follows: when the equipment is running, the synchronous belt 9 (the bottom surface of the synchronous belt 9 is higher on the left and lower on the right, and the distance between its bottom surface and the conveyor line 5 will be smaller as it goes to the right) and the conveyor belt on the conveyor line 5 run to the right at the same time, and the staff manually places the bottle cap 8 on the bottle mouth, and the bottle cap 8 and the bottle 6 run to the right together on the conveyor belt, and the top surface of the bottle cap 8 will get closer and closer to the bottom surface of the synchronous belt 9. When the bottle cap 8 contacts the bottom surface of the synchronous belt 9, it will be subjected to the vertical pressure of the synchronous belt 9, pressing the bottle cap 8 downward. Since the bottle 6 is placed on the conveyor belt 5 and will not move downward, the bottle cap 8 will be pressed into the bottle mouth of the bottle 6, and the bottle cap 8 will be pressed into a specific position of the bottle 6, that is, the lowest point of contact between the synchronous belt and the bottle cap. After the bottle and the bottle cap are pressed, they leave the synchronous belt and pass through the conveyor belt to enter the next process.

[0045] Therefore, through the linear capping machine provided by the present application, the overall height of the machine head can be adjusted through the first lifting screw and the second lifting screw to adapt to bottles of different heights, thereby achieving the effect of one capping machine adapting to bottles of different heights.
