Description

Technical Field

[0001] The utility model relates to the technical field of coating machines, in particular to a coating machine for producing medical cooling patches. Background Art

[0002] The coating machine is mainly used for the surface coating process production of film, paper, etc. This machine is to coat the rolled substrate with a layer of glue, coating or ink with specific functions, and then rewind it after drying. It uses a special multi-functional coating head, which can realize various forms of surface coating. The rewinding and unwinding of the coating machine are equipped with full-speed automatic film splicing mechanism, and PLC program tension closed-loop automatic control.

[0003] In the related technology, a Chinese patent document with application number CN202321688067.X proposes a coating mechanism of a coating machine. During the coating operation, a motor drives a stirring paddle to rotate to stir the paint inside the material trough to prevent the paint from settling. In addition, by setting a first baffle, it can buffer the paint when stirring the paint, greatly reducing the shaking amplitude of the paint above the first baffle, thereby improving the coating quality.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: the device uses a motor to drive the stirring paddle to rotate to prevent the paint from settling, and the first baffle is set to buffer the paint when stirring. Although the first baffle can buffer the paint when stirring the paint to a certain extent, when the motor drives the stirring paddle to rotate at an increased speed to evenly stir the paint in the material tank, the oscillation of the paint in the material tank increases, and the first baffle side may fail. The oscillation in the material tank will still affect the uneven coating on the coating roller. If the speed of the motor driving the stirring paddle is reduced, the coating may be unevenly stirred, which will also affect the feeding efficiency. Moreover, stirring the paint in the material tank in one direction only by a unidirectional stirring paddle may cause uneven stirring of the paint in the material tank. In view of this, a coating machine for the production of medical cooling patches is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1 and Figure 3 In this embodiment, a coating machine for producing a medical cooling patch includes a material trough 1, a coating roller 2 and a pressing roller 3. The lower part of the coating roller 2 is located in the material trough 1 and the upper part is higher than the material trough 1. The material trough 1 is provided with an adjusting mechanism 4 and a stirring mechanism 5.

[0021] The adjusting mechanism 4 includes a mounting plate 404, a first motor 401 and a threaded rod 402. The mounting plate 404 is fixed in the material trough 1. A plurality of through holes 405 which are evenly distributed are opened on the mounting plate 404. A rotatable threaded rod 402 is horizontally arranged in the material trough 1. A first motor 401 for driving the threaded rod 402 to rotate is fixedly installed on the material trough 1. Two fixed plates 407 which can move left and right at the same time are threadedly connected on the threaded rod 402. A plurality of cross bars 406 are fixed between the two fixed plates 407. Fixed blocks 403 corresponding to the through holes 405 are fixed on the cross bars 406.

[0022] The device starts the first motor 401, which drives the threaded rod 402 to rotate, and then drives the fixed plate 407 to move through the threaded rod 402, and then drives the cross bar 406 to move through the fixed plate 407, so that the fixed block 403 on the cross bar 406 moves with it, thereby adjusting the size of the through hole 405.

[0023] The upper end of the fixing block 403 is slidably connected to the lower end surface of the mounting plate 404 , so that when the fixing block 403 moves, it can block the through hole 405 .

[0024] At the same time, a sliding groove is provided on the inner side of the trough 1 to be slidably connected to the fixed plate 407, so as to limit the rotation tendency of the fixed plate 407 and enable it to move horizontally.

[0025] See also Figure 1-2The stirring mechanism 5 in this embodiment includes a first rotating shaft 501 and a second rotating shaft 502. A rotatable first rotating shaft 501 and two second rotating shafts 502 are horizontally arranged in the material trough 1. The two second rotating shafts 502 are located on the left and right sides of the first rotating shaft 501. A plurality of stirring blades 508 are fixed on the first rotating shaft 501 and the two second rotating shafts 502. The first rotating shaft 501 and the two second rotating shafts 502 are staggeredly distributed to facilitate sufficient stirring of the paint.

[0026] The device uses the first rotating shaft 501 and the second rotating shaft 502, and then the first rotating shaft 501 and the second rotating shaft 502 drive the stirring blades 508 on the upper part thereof to stir the paint evenly.

[0027] Among them, two driving wheels 506 are fixed on the first rotating shaft 501, and the driving wheels 506 are distributed up and down. A driven wheel 503 is fixed on the second rotating shaft 502. A second belt 507 is transmitted between the upper driving wheel 506 and the left driven wheel 503, and a second belt 507 is transmitted between the lower driving wheel 506 and the right driven wheel 503. A second motor 505 for driving the first rotating shaft 501 to rotate is fixedly installed on the material trough 1.

[0028] At the same time, by starting the second motor 505, the second motor 505 drives the first rotating shaft 501 to rotate, and the first rotating shaft 501 drives the two active wheels 506 to rotate, and the second belt 507 is driven to rotate by the upper active wheel 506 and the left driven wheel 503, and the lower active wheel 506 and the right driven wheel 503 drive the first belt 504 to rotate, so that the first rotating shaft 501 and the second rotating shaft 502 rotate at the same time, so that the first rotating shaft 501 and the second rotating shaft 502 drive the stirring blades 508 on their upper parts to evenly stir the paint.

[0029] The working principle of the above embodiment is:

[0030] When it is necessary to adjust and increase the speed of the second motor 505 to evenly stir the slurry in the material tank 1, start the first motor 401 to drive the threaded rod 402 to rotate, and then drive the fixed plate 407 to move through the threaded rod 402, and then drive the cross bar 406 to move through the fixed plate 407, so that the fixed block 403 on the cross bar 406 follows the movement, when the fixed block 403 is completely or a small gap is left between the fixed block 403 and the through hole 405.

[0031] At this time, the second motor 505 is started to drive the first rotating shaft 501 to rotate, and the first rotating shaft 501 drives the two active wheels 506 to rotate, and the second belt 507 is driven to rotate through the upper active wheel 506 and the left driven wheel 503, and the lower active wheel 506 and the right driven wheel 503 drive the first belt 504 to rotate, so that the first rotating shaft 501 and the second rotating shaft 502 rotate at the same time, so that the first rotating shaft 501 and the second rotating shaft 502 drive the stirring blades 508 on their upper parts to evenly stir the paint.

[0032] After stirring, the first motor 401 drives the cross bar 406 on the threaded rod 402 to move to increase the gap between the fixed block 403 and the through hole 405, so that the paint located above the mounting plate 404 can be mixed with the paint below. At this time, the rotation speed of the second motor 505 can be reduced, so that the first rotating shaft 501 and the second rotating shaft 502 drive the stirring blade 508 on the upper part to rotate at a slow speed to reduce the sedimentation speed of the paint. At this time, the oscillation will also decrease as the rotation speed of the stirring blade 508 decreases. After a period of time, repeat the above steps to quickly stir the paint in the material tank 1 to make it repeatedly mixed to avoid sedimentation.
