By arranging the spring 6, the fixing seat 9 is connected with the baffle 8 in a floating manner, which is equivalent to that the anti-collision strip 5 is connected with the baffle 8 in a floating manner. The anti-collision strip 5 is arranged on the die head 1 in a floating manner, and the anti-collision strip 5 can quickly respond after being hit by foreign matter.

[0028] In the embodiment of the present disclosure, the adjusting component 7 is a micrometer, and the micrometer is fixed to the fixing seat 9 through a screw. Specifically, the anti-collision strip 5 can be adjusted by the micrometer to move up and down, to adjust the relative height between the anti-collision strip 5 and the die lip 2, and to adjust the anti-collision strip 5 by the micrometer so that the anti-collision strip 5 and the die lip 2 are at the same height. The preset tension can be determined according to the weight of the anti-collision strip 5 or the fixing seat 9, which is not limited in the embodiment of the present disclosure.

[0029] In the embodiment of the present disclosure, the sliding component comprises a sliding block 10 and a sliding rail 11. The sliding block 10 is used to drive the anti-collision strip 5 to move on the sliding rail 11 when the anti-collision strip 5 is hit by foreign matter. The sliding block 10 can be fixedly connected with the anti-collision strip 5 through a screw, and the sliding rail 11 is fixed to the die head 1 through a bolt. The sliding block 10 and the sliding rail 11 can belong to the same component.

[0030] In the embodiment of the present disclosure, the foreign matter feedback component comprises an inductive grating ruler 12 arranged on the die head 1 to monitor the position of the anti-collision strip 5 and an inductive grating ruler reader 13 arranged on the anti-collision strip 5. Specifically, the inductive grating ruler 12 can be fixedly arranged on the back of the coating machine die head 1 through a bolt, and the inductive grating ruler reader 13 can be fixedly arranged on the anti-collision strip 5. The inductive grating ruler reader 13 is used to record the position of the anti-collision strip 5 adjusted by the adjusting component 7. When the position of the anti-collision strip 5 changes, an alarm information is triggered, and a signal for controlling the die head 1 to stop running is triggered.

[0031] In the embodiment of the present disclosure, in order to avoid that the die lip 2 is hit by foreign matter on the coated sheet 4 and damaged, the height of the anti-collision strip 5 from the coated sheet 4 can be not higher than the height of the die lip 2 from the coated sheet 4.

[0032] Referring to Figure 7 The utility model provides a preferable embodiment of coating machine, including coating machine body 15, be provided with drive arrangement 14 on coating machine body 15, and gantry 16 is set on drive arrangement 14, the coating machine die head of above-mentioned is installed on gantry 16, drive arrangement 14 is used to drive gantry 16 to move, to make die head 1 to the sheet 4 that is coated to carry out spraying.

[0033] In the embodiment of the present disclosure, in order to reduce the damage of large foreign matter to the coating machine die head 1, a protection mechanism for large foreign matter is provided, and the foreign matter feedback mechanism further comprises: a detection device arranged on the drive device 14, the detection device is used to detect the driving thrust change of the drive device 14 due to the impact of the anti-collision strip 5 by the foreign matter, and according to the driving thrust change, trigger an alarm information, control the drive device 14 to stop moving, so that the die head 1 stops moving.

[0034] Preferably, the drive device 14 can be configured as a linear motor. The detection device can be configured as a driver of linear motor thrust monitoring software connected with the linear motor 14. When the anti-collision strip 5 does not touch the foreign matter, the thrust curve of the linear motor is normal. When the anti-collision strip 5 touches the large foreign matter, the load of the linear motor increases sharply, so that the thrust curve changes abnormally. By monitoring and reading the load curve of the linear motor through the linear motor driver, the load change of the linear motor can be detected. When the load of the linear motor is abnormal, an alarm information is triggered, and a signal for controlling the coating machine to stop running is triggered, so as to prevent the die head 1 from being damaged by the impact of the foreign matter.

[0035] Referring to Figures 4-6 It needs to be specifically explained that according to the height of the anti-collision strip 5 from the coated sheet 4, the foreign matter can be divided into three types of foreign matter, which can be called large foreign matter 19, medium foreign matter 18 and small foreign matter 17. In the embodiment of the present disclosure, different height of foreign matter can provide specific scenarios of protection mechanism for coating machine die head 1 when the coating machine die lip 2 is impacted: when the coating machine starts to coat, the linear motor drives the gantry 16 to start moving. When the anti-collision strip 5 passes through the small foreign matter 17, the small foreign matter 17 is not high enough to touch the anti-collision strip 5, so it will not hit the die lip 2. At this time, no alarm will be sent. When the anti-collision strip 5 passes through the medium foreign matter 18, because the height of the medium foreign matter 18 is higher than the height of the anti-collision strip 5, the anti-collision strip 5 hits the medium foreign matter 18, and the anti-collision strip 5 will have an upward force, which makes the anti-collision strip 5 move upward. At this time, the inductive grating ruler 12 detects the change of the absolute position of the anti-collision strip 5 in the height direction, and immediately alarms, and the coating machine device stops moving. When the anti-collision strip 5 passes through the large foreign matter 19, the anti-collision strip 5 hits the large foreign matter 19, and when the load of the linear motor is abnormal, an alarm information is triggered, and the coating machine device stops moving, thereby protecting the die head 1 and the die lip 2.

[0036] The above merely describes the preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
