[0025] Embodiment

[0026] Refer to Figures 1-4 For the embodiment of the utility model, the embodiment provides a hot melt adhesive coating cooling device for medical adhesive tape cloth, which can uniformly disperse cold air to the surface of hot melt adhesive and achieve consistent cooling speed of each region of hot melt adhesive.

[0027] The bearing mechanism 100 comprises a fixed frame 101 and a support plate 102 fixedly connected to the top of the fixed frame 101;

[0028] It should be noted that through the cooperation of the fixed frame 101 and the support plate 102, the swing mechanism 200 and the cooling mechanism 300 can be stably supported.

[0029] The swinging mechanism 200 comprises a first motor 201 mounted on the outer side of the support plate 102, a cam disc 202 fixedly connected to the output end of the first motor 201 through a shaft coupling, a driving rod 203 slidingly connected to the inner wall of the cam disc 202, an inner threaded block 204 slidingly connected to the outer end surface of the driving rod 203, a threaded rod 205 threadedly connected to the inner surface of the inner threaded block 204, a support block 206 sleeved on the outer side of the threaded rod 205, a guide rail 207 fixedly connected to the inner side of the support plate 102 and cooperating with the support block 206, and a regulating assembly 208 arranged on the top of the support block 206.

[0030] It should be noted that the outer surface of the inner threaded block 204 is in sliding contact with the inner surface of the support block 206, and when the cam disc 202 rotates, it can drive one end of the driving rod 203 to move in a circular motion. Through the cooperation of the driving rod 203, the inner threaded block 204 and the threaded rod 205, the surface of the support block 206 and the guide rail 207 can be driven to move reciprocatingly and linearly, and the regulating assembly 208 is used to adjust the reciprocating movement distance of the support block 206.

[0031] In addition, a cooling mechanism 300 is arranged on the outer surface of the support block 206.

[0032] It should be further noted that the support block 206 moves reciprocatingly and linearly, which can drive the cooling mechanism 300 to move synchronously, so that the cold air is uniformly dispersed to the surface of the hot melt adhesive.

[0033] Specifically, the output end of the first motor 201 penetrates to the inner side of the support plate 102, the bottom of the threaded rod 205 is fixedly mounted on the inner wall of the support block 206 through a bearing, and the inner surface of the support block 206 is in sliding contact with the outer surface of the guide rail 207.

[0034] Further, the regulating assembly 208 comprises a rotating column 208a fixedly connected to the top of the support block 206 on both sides, a friction rod 208b rotatably connected to the outer surface of the rotating column 208a, and a spring 208c fixedly connected to the inner side of the friction rod 208b.

[0035] Preferably, the regulating assembly 208 further comprises a connecting shaft 208d rotatably connected to the inner surface of the threaded rod 205, a friction plate 208e fixedly connected to the outer surface of the connecting shaft 208d and cooperating with the friction rod 208b, and a knob 208f fixedly connected to the top of the connecting shaft 208d, and the penetrating end of the connecting shaft 208d is fixedly connected to the top of the threaded rod 205.

[0036] When the two friction rods 208b are in contact with the friction plate 208e at the same time, a strong friction force can be generated, thereby limiting the connecting shaft 208d. Pressing the two friction rods 208b can provide a pressure to the spring 208c, and the friction rods 208b are simultaneously separated from the friction plate 208e, so as to release the limitation on the connecting shaft 208d.

[0037] It should be noted that the cooling mechanism 300 comprises a fixed plate 301 fixedly connected to the outer surface of the threaded rod 205, and a storage battery 302 fixedly arranged on the top of the fixed plate 301.

[0038] Further, the cooling mechanism 300 further comprises a second motor 303 adaptedly arranged on the outer surface of the storage battery 302, and a centrifugal fan 304 arranged and fixedly connected to the top of the fixed plate 301 and cooperated with the second motor 303.

[0039] Specifically, the fixed plate 301 is electrically connected with the second motor 303, and the output end of the second motor 303 is fixedly connected with the rotor of the centrifugal fan 304 through a shaft coupling.

[0040] It should be noted that the storage battery 302 adopts a lithium ion battery with higher energy density and higher power, and the storage battery 302 is used to supply power to the second motor 303.

[0041] In use, rotating the knob 208f drives the connecting shaft 208d to rotate synchronously with the threaded rod 205, so that the inner threaded block 204 drives one end of the driving rod 203 to move linearly through the rotation of the threaded rod 205, thereby adjusting the torque of the driving rod 203. After the torque of the driving rod 203 is adjusted to an appropriate range, the first motor 201 and the second motor 303 are started to drive the cam disc 202 to rotate synchronously, the driving rod 203 is driven to move circularly through the cam disc 202, and the driving rod 203, the inner threaded block 204 and the threaded rod 205 are cooperated to drive the support block 206 to move linearly on the surface of the guide rail 207, so that the support block 206 drives the centrifugal fan 304 to move reciprocally; the rotor of the fan 304 is driven to rotate through the second motor 303, and the fan blades are driven to rotate synchronously to generate cold air, which is blown to the surface of the hot melt adhesive, so as to realize the effect that the cold air is uniformly dispersed on the surface of the hot melt adhesive, and the cooling speed of each region of the hot melt adhesive is consistent.

[0042] In summary, the centrifugal fan 304 is driven by the swing mechanism 200 to perform reciprocating linear motion, so that the cold air can be uniformly dispersed to the hot melt adhesive surface, ensuring that the cooling speed of each area of the hot melt adhesive is consistent, and the uniformity of the cooling effect is improved; the cooperation between the components in the adjustment assembly 208 can not only flexibly adjust the working range of the centrifugal fan 304 according to the medical adhesive tape with different coating widths and thicknesses, but also can fix the adjusted working range, so as to adapt to more different production demands and improve the application range of the equipment.
