Description

Technical Field

[0001] This utility model relates to the field of coating machines, and in particular to a slot coating machine with automatic gap adjustment. Background Technology

[0002] Currently available slot coating equipment cannot detect, adjust, or control the distance between the product and the die slot in real time. The gap between the left and right ends of the die slot and the product will change with the duration of equipment use. Furthermore, the platform is often a heated platform, and the physical deformation caused by temperature changes also affects the gap between the die slot and the product. Utility Model Content

[0003] The technical problem this invention aims to solve is: to address the technical problems described in the background art, this invention provides an automatic gap-adjustable slit coating machine. It uses a right height gauge and a left height gauge to detect the gap between the slit head and the product at both ends in real time. Then, based on the collected height information from both sides, it adjusts the tilt angle of the slit head using either a right or left height adjustment drive mechanism, ensuring that the slit head remains parallel to the product and guaranteeing the stability of the coating process.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] An automatic gap-adjustable slit coating machine includes a slit die head and a product platform. The slit die head is mounted on a swing plate, which is rotatably connected to a back plate via a shaft. The back plate is equipped with a right height adjustment drive mechanism for driving the swing plate to swing clockwise and a left height adjustment drive mechanism for driving the swing plate to swing counterclockwise. A right height gauge and a left height gauge are respectively mounted at both ends of the swing plate. The right height adjustment drive mechanism, the left height adjustment drive mechanism, the right height gauge, and the left height gauge are all electrically connected to a controller.

[0006] Specifically, both the right height adjustment drive mechanism and the left height adjustment drive mechanism are high displacement precision actuators, which are linear voice coil motors or piezoelectric actuators.

[0007] Specifically, both the right and left altimeters are dial gauges.

[0008] Specifically, the swing plate is provided with several screw holes for connecting bolts, and the back plate is provided with strip holes for bolts to pass through.

[0009] Specifically, the right height adjustment drive mechanism and the left height adjustment drive mechanism, which are parallel to each other and at the same height, are both located above the swing plate.

[0010] The beneficial effects of this utility model are as follows: This utility model provides an automatic gap adjustment slit coating machine. The gap between the slit head and the product at both ends is detected in real time using a right height gauge and a left height gauge. Then, based on the collected height information from both sides, the tilt angle of the slit head is adjusted by either the right or left height adjustment drive mechanism, ensuring that the slit head remains parallel to the product and guaranteeing the stability of the coating process.

[0014] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0015] Figure 1 This is a schematic diagram of the structure of this utility model.

[0016] As attached Figure 1 As shown, an automatic gap-adjustable slit coating machine includes a slit die head 1 and a product platform 2. The slit die head 1 is mounted on a swing plate 3, which is rotatably connected to a back plate via a shaft. The back plate is equipped with a right height adjustment drive mechanism 4 for driving the swing plate 3 to swing clockwise and a left height adjustment drive mechanism 5 for driving the swing plate 3 to swing counterclockwise. A right height gauge 6 and a left height gauge 7 are respectively mounted at both ends of the swing plate 3. All three mechanisms are electrically connected to a controller. The controller is a computer or a PLC.

[0017] Both the right height adjustment drive mechanism 4 and the left height adjustment drive mechanism 5 are high displacement precision actuators, which are linear voice coil motors or piezoelectric actuators.

[0018] Both the right altimeter 6 and the left altimeter 7 are dial gauges.

[0019] The swing plate 3 has several screw holes 8 for connecting bolts, and the back plate has slots for the bolts to pass through. By screwing the bolts into the screw holes 8 and through the slots, and then tightening the nuts, the swing plate 3 can be locked and fixed to the back plate.

[0020] The two parallel, same-height right height adjustment drive mechanisms 4 and left height adjustment drive mechanisms 5 are both located above the swing plate 3.

[0021] The working method of this application is as follows: when the product platform 2 carrying the product moves forward and passes the slit mold head 1, the right height measuring instrument 6 and the left height measuring instrument 7 on both sides will transmit the data information of the gap between the product and the two ends of the slit mold head 1 to the controller. The controller will then activate the right height adjustment drive mechanism 4 and the left height adjustment drive mechanism 5 according to the height difference between the left and right ends. When it is necessary to make the swing plate 3 and the slit mold head 1 swing clockwise by a certain angle, the moving end of the right height adjustment drive mechanism 4 moves down and pushes the swing plate 3 and the slit mold head 1 to swing clockwise.

[0022] When the swing plate 3 and the slit die head 1 are to swing counterclockwise by a certain angle, the moving end of the left height adjustment drive mechanism 5 moves downward and pushes the swing plate 3 and the slit die head 1 to swing counterclockwise. This keeps the slit die head 1 parallel to the product surface.

[0023] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
