[0047] Hydrocolloid dressings are made by mixing elastic polymerized hydrogels with synthetic rubber and adhesives. Existing hydrocolloid production equipment has a low degree of automation when producing hydrocolloids. During the production process, manual intervention is required, which affects the production efficiency and performance of the equipment.

[0048] The utility model provides a hydrocolloid production line, aiming at least to solve the problem that the automation degree of existing hydrocolloid production equipment is low.

[0049] See also Figures 1 to 7In one embodiment of the utility model, the hydrocolloid production line 100 includes a feeding device 1, a mixing device 2, an extrusion device 3 and a composite cutting device 4, wherein the feeding device 1 is used to provide a hydrocolloid raw material; the mixing device 2 is connected to the feeding device 1 to mix the hydrocolloid raw material provided by the feeding device 1; the extrusion device 3 is connected to the mixing device 2 to extrude the hydrocolloid raw material mixed by the mixing device 2; the composite cutting device 4 is connected to the extrusion device 3 to coat and cut the hydrocolloid raw material extruded by the extrusion device 3 to form a hydrocolloid.

[0050] In the technical solution of the utility model, the hydrocolloid production line 100 includes a feeding device 1, a mixing device 2, an extrusion device 3, and a composite cutting device 4. In this way, after the feeding device 1 provides the mixing device 2 with the raw materials required for producing the hydrocolloid, the mixing device 2 stirs and mixes the various hydrocolloid raw materials, and then the extrusion device 3 extrude the mixed hydrocolloid raw materials, and then the composite cutting device 4 coats and cuts the extruded hydrocolloid raw materials, thereby forming a finished hydrocolloid product. The overall structure is automated from the raw materials of the hydrocolloid to the formation cost, saving labor.

[0051] Please refer to Figures 1 to 3 In order to be able to quantitatively feed the mixing device 2, in an embodiment of the utility model, the feeding device 1 includes a silo 11, a conveying device and a weighing device. The silo 11 is at least one, and the silo 11 includes a main silo body 111 for storing hydrocolloid raw materials, and a metering silo 112, the metering silo 112 extends in the transverse direction and has a discharge end for docking with the mixing device 2; the conveying device includes a spiral metering rod 12 extending in the transverse direction and rotatably arranged relative to the metering silo 112, one end of the spiral metering rod 12 is located in the main silo body 111, and the other end is located in the metering silo 112, the conveying device also includes a metering drive connected to the spiral metering rod 12, the metering drive is used to drive the spiral metering rod 12 to rotate; the weighing device is used to obtain the weight of the hydrocolloid raw material in the metering silo 112. In this arrangement, the main bin body 111 stores hydrocolloid raw materials, and the spiral metering rod 12 is driven to rotate by the metering drive member to transport the hydrocolloid raw materials in the main bin body 111 to the metering bin 112 in the transverse direction. The weight of the hydrocolloid raw materials in the metering bin 112 is obtained by the weighing device, thereby realizing quantitative feeding of the mixing device 2.

[0052] Furthermore, in an embodiment of the present invention, in order to enable more accurate feeding, the hydrocolloid production line 100 also includes a controller electrically connected to the weighing device and the metering drive member. By setting a preset amount that is less than and very close to the required amount, when the weighing device obtains that the weight of the hydrocolloid raw material in the metering bin 112 reaches the preset amount, the metering drive member is controlled by the controller to change the rotation speed of the spiral metering rod 12 from fast to slow, thereby providing metering accuracy.

[0053] The silo 11, the conveying device and the weighing device can realize the quantitative conveying of powder and solid, and the raw materials of the hydrocolloid usually also include liquid processing aids, etc., so in the embodiments of the present utility model, please refer to Figure 2 The feeding device 1 also includes a box for storing liquid raw materials and a metering pump connected to the box, and the metering pump is used to quantitatively feed the mixing device.

[0054] In order to reduce the clogging of powder and fixed raw materials in the silo 11, in the embodiment of the present utility model, please refer to Figure 3 The feeding device 1 further includes a vibrating member 13 disposed on the main bin body 111, and the vibrating member 13 is used to vibrate the hydrocolloid raw material in the main bin body 111; thus, the vibrating member 13 vibrates the hydrocolloid raw material in the main bin body 111 to improve the smoothness of the raw material conveying by the spiral metering rod 12. The present design does not limit the specific form of the vibrating member 13, and the vibrating member 13 can be a vibrating motor, a vibrating air hammer, or other components or parts that can produce a vibrating effect.

[0055] In order to improve the quality of the raw materials in the silo 11, thereby improving the quality of the hydrocolloid finished product, in an embodiment of the utility model, the feeding device 1 also includes a dust collector 14 connected to the main silo body 111. The dust in the silo 11 is reduced by the dust collector 14, thereby improving the quality of the hydrocolloid finished product. At the same time, when the raw materials are vibrated by the vibrating member 13, the dust collector 14 can reduce the dust phenomenon.

[0056] Among them, the present design does not limit the specific type of the dust collector 14 and the way of connecting with the main bin body 111. For example, the dust collector 14 can be connected with the main bin body 111 at the air inlet end and directly connected to the outside at the air outlet end. An air inlet pipe is set on the main bin body 111 to replenish air. The dust collector 14 can be connected with the main bin body 111 at both the air inlet end and the air outlet end. After extracting the air in the main bin body 111 and filtering the dust through its internal components, the air is directly transported to the main bin body 111.

[0057] Please refer to Figure 4 In the embodiment of the utility model, the mixing device 2 includes a mixing bin 21 and a mixing device, the mixing bin 21 has a feeding end for docking with the feeding device 1 and a discharging end for docking with the extrusion device 3; the mixing device includes a stirring blade 22 rotating in the mixing bin 21 and a stirring driving member drivingly connected to the stirring blade 22, the stirring driving member is used to drive the stirring blade 22 to rotate, so as to stir and mix the hydrocolloid raw materials in the mixing device. In this way, after the hydrocolloid raw materials provided by the feeding device 1 enter the mixing bin 21, the stirring driving member is started to drive the stirring blade 22 to rotate, thereby stirring and mixing the raw materials.

[0058] After the raw materials in the mixing bin 21 are mixed, there are many ways to discharge the materials. For example, a discharge pipe and a valve can be directly set at the bottom to discharge the materials under the action of gravity. However, the raw materials of the hydrocolloid usually contain colloids, which can easily cause the valve to be blocked and the discharge speed to be slow. In the embodiment of the utility model, please refer to Figure 4 The mixing device 2 further includes a conveying device, which includes a conveying rod 23 rotatably arranged in the mixing bin 21 and located below the stirring blade 22, and a conveying driving member, wherein the conveying rod 23 extends in the transverse direction and one end thereof passes through the discharge end of the mixing bin 21 to the outside of the mixing bin 21, and the conveying driving member is drivingly connected to the conveying rod 23 to drive the conveying rod 23 to rotate. In this way, when discharging is required, the conveying driving member drives the conveying rod 23 to rotate, thereby driving the raw materials in the mixing bin 21 to be discharged from the mixing bin 21 in the transverse direction; compared with discharging under the action of gravity, the forced discharge of the materials by the conveying rod 23 can reduce the interference of the colloid on the discharge, and at the same time, the rotation of the conveying rod 23 can further stir and mix the raw materials.

[0059] It is understandable that the raw materials of the hydrocolloid include rubber. In order to improve the mixing efficiency and quality, in the embodiment of the utility model, the stirring blades 22 are provided in two, and the two stirring blades 22 rotate in opposite directions, which can tear the rubber.

[0060] Furthermore, in order to increase the shear force of the stirring blade 22, the stirring blade 22 may be a Z-shaped blade.

[0061] Please refer to Figure 5In the embodiment of the utility model, the extrusion device 3 includes an extrusion barrel 31 and an extrusion device, wherein the extrusion barrel 31 has a feed end for docking with the mixing device 2 and a discharge end for docking with the composite cutting device 4; the extrusion device includes an extrusion screw 32 rotatably arranged in the extrusion barrel 31 and extending in the transverse direction, and an extrusion drive, wherein the extrusion drive is drivingly connected to the extrusion screw 32 to drive the extrusion screw 32 to rotate, so as to extrude the hydrocolloid raw material in the extrusion barrel 31 out of its discharge end. In this way, after the mixed raw materials enter the extrusion barrel 31, the extrusion drive drives the rotation of the screw, and then cooperates with the side wall of the extrusion barrel 31 to extrude the raw materials, and the raw materials are squeezed and compacted.

[0062] In order to improve the extrusion effect of the extrusion device 3, in the embodiment of the present utility model, please refer to Figure 5 The outer diameter of the extrusion screw 32 is reduced in the direction from the feed end of the extrusion barrel 31 to the discharge end of the extrusion barrel 31, and the inner wall of the extrusion barrel 31 is adapted to the extrusion screw 32; in this way, the extrusion screw 32 is conically arranged, which has a better extrusion and compaction effect.

[0063] Of course, the method of improving the extrusion compaction effect is not limited to this. In one embodiment, the extrusion screw 32 is provided with two, and the extrusion drive is connected to both of the extrusion screws 32 to drive the two extrusion screws 32 to rotate in opposite directions. In this way, the extrusion drive drives the two extrusion screws 32 to rotate relative to each other, which is conducive to further improving the extrusion effect.

[0064] There are many forms of the extrusion drive member, which may be two motors driving the two extrusion screws 32 respectively, or a motor driving one of the extrusion screws 32 to rotate, and then driving the other extrusion screw 32 to rotate through gear meshing.

[0065] Please refer to Figure 1 , Figure 6 and Figure 7In an embodiment of the utility model, the composite cutting device 4 includes a frame 41, a first coating device 42, a coating device 43, a second coating device 44 and a cutting device. The first coating device 42 is used to dock with the extrusion device 3, and includes a substrate winding roller 421, a substrate unwinding roller 422 and a plurality of substrate transmission rollers 423 rotatably arranged relative to the frame 41. The first coating device 42 also includes a first coating driving member at least connected to the substrate winding roller 421 to at least drive the substrate winding roller 421 to rotate, so that the substrate and the hydrocolloid raw material extruded by the extrusion device 3 on the substrate can be transported in the horizontal direction. The coating device 43 includes two extrusion rollers 431 rotatably arranged relative to the frame 41, and the two extrusion rollers are arranged at intervals in the up and down directions to have an extrusion gap. The device 43 also includes an extrusion driving member drivingly connected to the two extrusion rollers to drive the two extrusion rollers to rotate in opposite directions to extrude the hydrocolloid raw material on the substrate; the second coating device 44 includes a release film winding roller, a release film unwinding roller and a plurality of release film driving rollers rotatably arranged relative to the frame 41, and the second coating device 44 also includes a second coating driving member drivingly connected to at least the release film winding roller to at least drive the release film winding roller to rotate to cover the extruded hydrocolloid raw material with a release film. The cutting device is arranged on the frame 41, including a cutting knife 45 movable in the up and down directions relative to the frame 41, and a cutting driving member, the cutting driving member is drivingly connected to the cutting knife 45 to drive the cutting knife 45 to move in the up and down directions, so as to cover the release film on the hydrocolloid raw material for cutting to form a hydrocolloid. In this arrangement, the substrate can be transported in the transverse direction through the substrate winding roller 421, the substrate unwinding roller 422, the multiple substrate driving rollers 423 and the first coating driving member. After the material extruded by the extrusion device 3 falls on the substrate, the material is squeezed by the two squeezing rollers so that the material is evenly distributed on the substrate. A layer of release film is covered on the hydrocolloid raw material by the release film winding roller, the release film unwinding roller and the multiple release film driving rollers, thereby playing a protective role. After coating, the cutting knife 45 is driven up and down by the cutting driving member to disassemble the substrate and the release film, thereby forming a hydrocolloid finished product.

[0066] Wherein, the substrate can be PE or PU.

[0067] In order to adjust the thickness of the hydrocolloid product, in the embodiment of the utility model, at least one of the two squeezing rollers 431 is arranged to be movable in the up-down direction relative to the other, and the second film-coating driving member includes an adjusting driving member 432 drivingly connected to at least one of the squeezing rollers to drive it to move in the up-down direction to adjust the squeezing gap. In this way, the squeezing roller is driven to move in the up-down direction by the adjusting driving member 432, so as to adjust the distance between the two squeezing rollers, that is, to adjust the squeezing gap, so as to change the thickness of the hydrocolloid after squeezing.

[0068] It is understandable that after the hydrocolloid raw material is extruded by the extrusion device 3, the raw material will become relatively hard, which is not conducive to the extrusion of the raw material by the extrusion roller. Therefore, in the embodiment of the utility model, the composite cutting device 4 also includes a preheating device 46 and a cooling device 47. The preheating device 46, the coating device 43 and the cooling device 47 are sequentially arranged in a direction away from the extrusion device 3. In this way, before extrusion, the raw material is softened by the preheating device 46 to facilitate extrusion. After extrusion, the raw material is softened by the cooling device 47 to prevent the material from moving when the release film is subsequently covered, thereby affecting the quality of the hydrocolloid finished product.

[0069] The present design does not limit the specific forms of the preheating device 46 and the cooling device 47. The preheating device 46 may adopt radiation heating or hot air heating, and the cooling device 47 may adopt cold air or heat exchange with the substrate for cooling.

[0070] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
