[0028] The present invention is described in detail below in conjunction with specific embodiments.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or connected through one or more intermediate media. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances. The directional words that appear in the present utility model are to better illustrate the characteristics of the features and the relationship between the features. It should be understood that when the placement direction of the present utility model changes, the characteristics of the features and the direction of the relationship between the features also change accordingly. Therefore, the directional words do not constitute an absolute limitation on the characteristics of the features and the relationship between the features in space, but only play a relative limitation role.

[0030] like Figures 1 to 11 As shown, the utility model provides an automatic cutting production line for thermal insulation strips, including an extrusion mechanism 1 and a cutting mechanism 2. The extrusion mechanism 1 is used to extrude the thermal insulation strips, and the cutting mechanism 2 is used to cut the extruded thermal insulation strips. The cutting mechanism 2 includes a cutting machine chassis 20, a front cutting assembly 21, a terminal cutting assembly 23, and a guide assembly 22. The terminal cutting assembly 23 and the front cutting assembly 21 are used to cut the front end and the terminal of the thermal insulation strips, respectively, and the guide assembly 22 is used to guide the thermal insulation strips.

[0031] The guide assembly 22 includes a guide frame 220, a guide platform 221, a side bracket 222, a side push driving member 223, a bridge frame 224 and a guide component 225. The guide frame 220 is installed on the cutting machine chassis 20, the guide platform 221 is installed on the guide frame 220, the side bracket 222 is installed on the guide platform 221, and the side push driving member 223 is installed on the side bracket 222. The side push driving member 223 is used to drive the bridge frame 224 to slide on the guide platform 221. A plurality of guide components 225 are installed at the bottom of the bridge frame 224.

[0032] The guide component 225 includes an auxiliary elastic member 2252, a side baffle 2253, a lifting slider 2251 and a sliding sleeve 2250. The sliding sleeve 2250 is connected to the bridging frame 224. The lifting slider 2251 can slide in the sliding sleeve 2250, and an auxiliary elastic member 2252 is installed between the sliding sleeve 2250 and the lifting slider 2251. The side baffle 2253 is connected to the bottom of the lifting slider 2251, and multiple groups of side baffles 2253 are placed alternately in an inclined folded manner.

[0033] In this embodiment, two groups of bridging frames 224 are connected to the side push driving member 223, and the bridging frames 224 are distributed on both sides of the guide platform 221, one on the left and one on the right, and the side baffles 2253 in the guide components 225 installed on the bridging frames 224 on both sides are stacked in opposite directions.

[0034] Through the above design scheme, when the thermal insulation strip extruded by the extrusion mechanism 1 reaches the guide platform 221, the side baffles 2253 placed alternately at an angle can limit the thermal insulation strip to the middle position of the guide platform 221, thereby preventing the thermal insulation strip from slipping out of the guide platform 221 and affecting the cutting accuracy when the length of the thermal insulation strip is too long.

[0035] In this embodiment, the front-end cutting assembly 21 includes a front-end cutting table 210, a front-end clamping drive 214, a front-end pressure block 212, a clustering baffle 213 and a front-end sliding drive 215. The front-end sliding drive 215 is used to drive the front-end cutting table 210 to slide on the cutting machine chassis 20. The front-end clamping drive 214 is installed on the front-end cutting table 210 through the front-end bridge 211. The front-end clamping drive 214 is used to drive the front-end pressure block 212 to move closer to or away from the front-end cutting table 210. A lifting cutting saw is provided in the front-end cutting table 210, and the lifting cutting saw can be raised or lowered in the front-end cutting table 210. The front-end pressure block 212 is provided with a front-end buffer groove at the corresponding saw blade. The clustering baffle 213 is installed on the front-end cutting table 210.

[0036] In this embodiment, the end cutting assembly 23 includes an end slide 231, an end cutting table 233, an end clamping drive 237, a flap 235, an end pressure block 236, an end sliding drive 232 and a slide sliding drive 230; the slide sliding drive 230 is used to drive the end slide 231 to slide on the cutting machine chassis 20, the end sliding drive 232 is used to drive the end cutting table 233 to slide on the end slide 231, and the end clamping drive 237 is installed on the end cutting table 233 through the end bridge 234; the flap 235 is installed on the end bridge 234 through a hinged seat; a lifting cutting saw is provided in the end cutting table 233, and the lifting cutting saw can be raised or lowered in the end cutting table 233, and the end pressure block 236 is provided with a front end buffer groove at the corresponding saw blade.

[0037] Through the above-mentioned design scheme, when the length of the extruded insulation strip reaches the requirement and the insulation strip needs to be cut, the front end clamping driver 214 and the end clamping driver 237 simultaneously drive the front end pressure block 212 and the end pressure block 236 to press down respectively, and press the insulation strip on the guide table 221. Then the lifting and cutting saws in the front end cutting table 210 and the end cutting table 233 slowly rise to cut the insulation strip; the side push driver 223 can drive the side end bracket 222 to drive multiple groups of side baffles 2253 to slide on the guide table 221. The multiple groups of side baffles 2253 can push the insulation strip that reaches a preset length after cutting to the side, so as to avoid the insulation strip that has been cut from remaining on the guide table 221 and affecting the subsequent extrusion work.

[0038] In this embodiment, the guide platform 221 includes a smooth portion and a bending portion, and a material frame 3 is arranged below the bending portion; the smooth portion is used to ensure that the extruded insulation strips can move forward smoothly; the bending portion is used to guide the cut insulation strips so that they can slide into the material frame 3 for collection.

[0039] When the side baffle 2253 is in the smooth part, the auxiliary elastic member 2252 presses against the lifting slider 2251, so that the side baffle 2253 presses against the smooth part. Under the action of the auxiliary elastic member 2252, the side baffle 2253 can be stably pressed to prevent the extruded insulation strip from pushing the side baffle 2253 away and sliding out of the guide platform 221.

[0040] Through the above design scheme, during normal operation, the extrusion mechanism 1 continuously extrudes the thermal insulation strip, and the staff will pull the thermal insulation strip extruded to a certain length into the cutting mechanism 2, and the thermal insulation strip enters the front cutting assembly 21 from the clustering baffle 213. The extrusion mechanism 1 continuously extrude the thermal insulation strip to increase its length, and the thermal insulation strip enters the guide assembly 22 from the front cutting assembly 21. The side baffle 2253 guides the thermal insulation strip to prevent it from sliding out of the guide platform 221. When the length of the extruded thermal insulation strip reaches the preset value, the thermal insulation strip will push open the flap 235 to trigger an alarm to remind the staff. Since the initial lengths of the insulation strips output by different extrusion nozzles 12 during the initial extrusion are different, it is necessary to wait for a while for the end cutting component 23 to cut off the end of the insulation strip, then the end pressure block 236 and the front end pressure block 212 press the insulation strip, and then the lifting cutting saw rises to cut the insulation strip; after completing the cutting work, the front end sliding drive 215 and the end sliding drive 232 respectively drive the front end cutting table 210 and the end cutting table 233 to slide to both sides respectively, to prevent the front end bridge 211 and the end bridge 234 from affecting the subsequent unloading work.

[0041] When the cutting length needs to be adjusted, the end sliding drive 232 can drive the end slide 231 to slide on the cutting machine base 20, and then replace the guide table 221 and the bridge frame 224 of appropriate length. By increasing or decreasing the number of guide components 225 on the bridge frame 224, it can be ensured that the insulation belt will not shift during extrusion.

[0042] In this embodiment, the extrusion mechanism 1 includes a drying cylinder 11, a hot melt extruder 10, an extrusion nozzle 12 and a cooling block 13. The drying cylinder 11 is installed on the hot melt extruder 10, a detachable extrusion nozzle 12 is installed on the hot melt extruder 10, and a cooling block 13 is installed at the extrusion nozzle 12.

[0043] Through the above-mentioned design scheme, the raw materials used to produce the thermal insulation strips enter the hot melt extruder 10 through the drying cylinder 11, and the staff can replace the required extrusion nozzle 12 according to the needs. The thermal insulation strip extruded from the extrusion nozzle 12 will be quickly cooled and shaped under the action of the cooling block 13 to prevent the extruded thermal insulation strip from deforming under the action of its own high temperature. In this embodiment, multiple sets of heating heads are installed on the extrusion nozzle 12 to ensure that the temperature of the extrusion nozzle 12 meets the hot melt requirements; the cooling block 13 is connected to the external cooling water source, and the cooling water source flows through the cooling block 13 through the water supply pipe to ensure that the cooling block 13 can quickly cool the thermal insulation strip for a long time.

[0044] In this embodiment, a traction assembly 4 is provided between the extrusion mechanism 1 and the cutting mechanism 2. The traction assembly 4 includes a plurality of traction rollers 41 and a traction drive 40. The traction drive 40 is used to drive the traction rollers 41 to pull the thermal insulation strips.

[0045] In this embodiment, a clustering frame 5 is provided between the traction assembly 4 and the cutting mechanism 2; the clustering frame 5 can be used to lift the thermal insulation strips and also limit the extruded thermal insulation strips to a certain range to prevent the thermal insulation strips from scattering after being cut.

[0046] Compared with the prior art, the utility model provides an automatic insulation strip cutting production line. When the insulation strips are produced and processed, the insulation strips extruded from the extrusion nozzle 12 are guided by the traction assembly 4 and the cluster frame 5 into the cutting mechanism 2. When the insulation strips slide on the guide platform 221, the alternately placed side baffles 2253 can prevent the insulation strips from falling out of the guide platform 221 during extrusion, thereby ensuring that the insulation strips can be cut smoothly.

[0047] In the absence of conflict, the above-mentioned embodiments and features thereof may be combined with each other.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
