Description

Technical Field

[0001] The utility model relates to the technical field of medical dressing slurry coating, in particular to a medical dressing slurry coating device. Background Art

The conveying mechanism is composed of a pair of feeding roller assemblies 202 and a pair of discharging roller assemblies 203. The feeding roller assemblies and the discharging roller assemblies squeeze the upper and lower sides of the medical dressing respectively, and drive the medical dressing 204 to move forward after rotation. The coating mechanism is arranged between the feeding roller assemblies and the discharging roller assemblies, and coats the slurry 205 on the upper side of the medical dressing downward.

[0003] In the existing medical dressing slurry coating device, after the slurry is coated and passes through the discharging roller assembly, it is squeezed by the discharging roller assembly. On the one hand, when the discharging roller assembly presses over the slurry, it is easy to take away the slurry, resulting in a reduction in the slurry on the upper side of the medical dressing. On the other hand, when the slurry is not completely dry, the discharging roller assembly will press the slurry open, affecting the product quality. Content of the Utility Model

[0016] Next, through embodiments and in conjunction with the drawings, the technical solutions of the present invention will be further specifically described.

[0017] See Figure 1, A medical dressing slurry coating device, comprising: a conveying mechanism 3, a coating mechanism 4, and an oven 6 for drying the slurry 5. The conveying mechanism 3 includes a frame 31, a first conveyor belt 32, and a squeezing roller 33. The first conveyor belt 32 is horizontally installed on the upper side of the frame 31. The squeezing roller 33 is rotatably connected to the frame 31 and can press the medical dressing 7 against the upper side of the input end of the first conveyor belt 32. The first conveyor belt 32 supports the lower side of the medical dressing 7 and drives the medical dressing 7 to move forward; the coating mechanism 4 is arranged on the output side of the squeezing roller 33 and is located above the first conveyor belt 32. The coating mechanism 4 is used to coat the slurry 5 on the upper side of the medical dressing 7; the oven 6 is installed on the upper side of the frame 31 and is arranged on the side of the coating mechanism 4 away from the squeezing roller 33. A through hole 8 is provided on the oven 6, and the first conveyor belt 32 passes through the through hole 8 and passes through the oven 6.

[0018] With the above settings, first, after the slurry 5 is coated on the medical dressing 7, it will not be rolled, protecting the slurry 5 from being damaged and improving the coating quality of the slurry 5; second, on the one hand, the oven 6 can dry the coating entering the oven 6, and on the other hand, it also heats the first conveyor belt 32. The medical dressing 7 and the slurry 5 are preheated by the first conveyor belt 32 before entering the oven 6, accelerating the drying speed.

[0019] In this application, the squeezing roller 33 presses the medical dressing 7 against the input end of the first conveyor belt 32 to prevent slipping between the medical dressing 7 and the first conveyor belt 32; after the first conveyor belt 32 operates, the medical dressing 7 to be coated moves forward under the action of the first conveyor belt 32; the medical dressing 7 is horizontally spread on the upper side of the first conveyor belt 32 and moves forward, passing through the coating mechanism 4 and the oven 6 in sequence. Among them, the coating mechanism 4 can refer to existing coating devices, and the oven 6 can be purchased from the market; the coating mechanism 4 coats the slurry 5 on the upper side of the medical dressing 7. After the medical dressing 7 with the slurry 5 enters the oven 6, the oven 6 dries the slurry 5 on the medical dressing 7. The dried medical dressing 7 leaves the oven 6 with the first conveyor belt 32 and enters the next process; the first conveyor belt 32 is made of heat-resistant material. When the first conveyor belt 32 passes through the oven 6, the oven 6 heats the first conveyor belt 32, making the temperature of the first conveyor belt 32 relatively high. The first conveyor belt 32 can preheat the medical dressing 7 and the slurry 5 coated on the upper side of the medical dressing 7, improving the drying efficiency.

[0020] As an implementation manner, the conveying mechanism 3 further includes a second conveyor belt 34. The second conveyor belt 34 is installed on the upper side of the frame 31 and is connected to the first conveyor belt 32. The coating device further includes a cutting mechanism 9. The cutting mechanism 9 includes: a gantry 91, a support plate 92, a blade 93, and a driving mechanism 94. The gantry 91 is installed on the upper side of the frame 31, and the movement path of the medical dressing 7 passes through the gantry 91. The support plate 92 is installed in the gantry 91 and is located between the first conveyor belt 32 and the second conveyor belt 34. The upper side of the support plate 92 is flush with the upper side of the first conveyor belt 32. The driving mechanism 94 is vertically installed on the gantry 91. The output shaft of the driving mechanism 94 faces downward and is installed with the blade 93. The blade 93 is used to cut off the medical dressing 7.

[0021] Through the above settings, the medical dressing 7 can be cut into segments for output, which is convenient for later production into finished products.

[0022] In this application, the upper side of the second conveyor belt 34 is flush with the upper side of the first conveyor belt 32. The gantry 91 is used to support the support plate 92. The support plate 92 is used to transfer the medical dressing 7 output by the first conveyor belt 32 to the second conveyor belt 34 and provide a support point for the blade 93 to cut. When the driving mechanism 94 drives the blade 93 to move downward, the blade 93 cuts off the medical dressing 7 on the upper side of the support plate 92. The cut medical dressing 7 is output forward under the action of the second conveyor belt 34. The driving mechanism drives the blade 93 to reciprocate up and down to output the medical dressing 7 in segments. The length of each segment of the medical dressing 7 is longer than the length of the support plate 92. The coating mechanism 4 coats the slurry 5 at intervals, and the coating frequency is adapted to the cutting frequency of the blade 93. The blade 93 will not touch the slurry 5 when cutting.

[0023] As an implementation manner, the driving mechanism 94 is set as an electric cylinder or a pneumatic cylinder.

[0024] As an implementation manner, the oven 6 includes a box body 61 and heating sheets 62. The box body 61 is installed on the upper side of the frame 31. Through holes 8 are provided on opposite sides of the box body 61. The heating sheets 62 are installed at the inner bottom of the box body 61.

[0025] Through the above settings, the box body 61 plays a heat preservation role, and the heating sheets 62 raise the temperature inside the box body 61 to dry the slurry 5.

[0026] As an implementation manner, the coating mechanism 4 is installed on one side of the box body 61 close to the squeezing roller 33 through a bracket 10.
