Description

Technical Field

[0001] The utility model relates to the technical field of foam processing equipment, in particular to a foam welding and trimming mechanism. Background Art

[0002] Foam is a soft, elastic and hygroscopic material, which is usually made of polyester fiber, polyurethane and other materials. At present, due to its excellent physical and chemical properties, foam is widely used in various fields such as cushioning, sound insulation and heat preservation.

[0003] Foam welding technology is to melt the surface of the foam material by heating, and make it contact and bond with the surface of another foam material or different materials to form a strong connection. During the welding process, it is necessary to control parameters such as heating temperature, time and pressure to ensure the quality and stability of the welding.

[0004] Based on this, Chinese patent CN110027218B discloses a plastic foam block welding device, which includes a frame, a lower positioning cavity for placing a lower plastic foam block on the frame, a vacuum suction cup assembly directly above the lower positioning cavity, a positioning ring that fits the outer wall of the upper plastic foam block on the lower surface of the vacuum suction cup assembly, and a cylinder for driving the vacuum suction cup assembly to move up and down and detachably connected to the vacuum suction cup assembly on the frame, a wire placement channel arranged along the inner wall of the lower positioning cavity and connected to the lower positioning cavity is arranged in the frame, a heating wire is passed through the wire placement channel, and a power supply device electrically connected to the heating wire is arranged in the frame; this foam block welding device has the advantage of being able to automatically complete the welding of the upper plastic foam block and the lower plastic foam block.

[0005] However, the foam block welding equipment disclosed above still has the technical problem of being unable to trim the foam. Specifically, when welding the foam block, it is necessary to first preheat the hot press head to the set temperature to ensure that the temperature is stable during the welding process; then correctly place the foam material to be welded in the welding area to ensure that the two surfaces to be welded are in close contact; then, press the hot press head down and heat it according to the set temperature and time to melt the foam surface and combine with the other surface. During the welding process, uneven welding edges often appear at the edges of the foam block; thereafter, the user is often required to manually perform secondary trimming on the edges of the foam to improve the appearance of the finished foam welding product. The manual trimming process of the foam is not conducive to improving the production efficiency of mass processing of foam. Utility Model Content

[0027] Please refer to Figures 1 to 3 , a foam welding and trimming mechanism of the present utility model includes: a frame 1, a first driving mechanism 2, a second driving mechanism 3, a sliding guide frame 4, a pressing action structure 5, a welding action structure 6, a first trimming structure 7 and a second trimming structure 8; the first driving mechanism 2 and the second driving mechanism 3 are respectively arranged on the side surface of the frame 1; the first driving mechanism 2 is arranged above the second driving mechanism 3; the sliding guide frame 4 is respectively connected to the first driving mechanism 2 and the second driving mechanism 3; the pressing action structure 5 and the welding action structure 6 are relatively movably arranged on the side surface of the frame 1, the first driving mechanism 2 is drivingly connected to the pressing action structure 5, and the second driving mechanism 3 is drivingly connected to the welding action structure 6; the first trimming structure 7 is connected to the first driving mechanism 2, and the second trimming structure 8 is connected to the second driving mechanism 3.

[0028] Specifically, when a foam welding and trimming mechanism of the present utility model is in the working process, the materials to be welded with the foam all pass through between the crimping action structure 5 and the welding action structure 6. After that, the first driving mechanism 2 drives the crimping action structure 5 to move along the guiding of the sliding guiding frame 4 towards the direction close to the welding action structure 6, so as to press the materials to be welded between the crimping action structure 5 and the welding action structure 6; then, the welding action structure 6 can generate heat to realize welding between the two materials. At this time, there is a gap between the first trimming structure 7 and the second trimming structure 8, and they will not abut against the surface of the welded materials. Then, the second driving mechanism 3 drives the welding action structure 6 to rise to further press and fit the welded materials. At this time, the welding action structure 6 will be pressed and rebound a preset distance, and the second trimming structure 8 will move further towards the direction of the first trimming structure 7 under the drive of the second driving mechanism 3, so that the first trimming structure 7 and the second trimming structure 8 perform cutting and trimming processing on the edges of the welded materials. After the trimming action is completed, the first driving mechanism 2 and the second driving mechanism 3 respectively drive each component to reset. At this time, the foam materials can complete the process flow of welding processing and post-welding trimming processing at the same time; compared with the existing technology, the processing efficiency of welding and trimming processing is significantly improved.

[0029] Furthermore, the machine frame 1 has a support frame 101 and a conveying window structure 102; the conveying window structure 102 is arranged on the side surface of the support frame 101, and the conveying window structure 102 is arranged adjacent to the crimping action structure 5 and the welding action structure 6. Specifically, after the materials to be processed pass through between the crimping action structure 5 and the welding action structure 6, they enter the next working station from the conveying window structure 102.

[0030] Furthermore, the first driving mechanism 2 has a first cylinder structure 201, a first telescopic rod 202, a first connecting piece 203 and a first sliding block 204; the first cylinder structure 201 is arranged at the upper end of the sliding guiding frame 4, and the first cylinder structure 201 is drivingly connected with the first telescopic rod 202; the first connecting piece 203 connects the first telescopic rod 202 and the first sliding block 204 respectively, the first sliding block 204 is movably connected in the sliding guiding frame 4, and the first sliding block 204 is respectively connected with the crimping action structure 5 and the first trimming structure 7.

[0031] Further, the second driving mechanism 3 includes a second cylinder structure 301, a second telescopic rod 302, a second connecting member 303, and a second sliding block 304; the second cylinder structure 301 is disposed at the lower end of the sliding guide frame 4, and the second cylinder structure 301 is drivingly connected to the second telescopic rod 302; the second connecting member 303 connects the second telescopic rod 302 and the second sliding block 304 respectively, the second sliding block 304 is movably connected to the sliding guide frame 4, and the second sliding block 304 is connected to the welding action structure 6 and the second trimming structure 8 respectively.

[0032] Further, the welding action structure 6 includes a heating part 601, a plurality of welding connecting columns 602, and a plurality of welding return springs 603; the heating part 601 is disposed opposite to the pressing action structure 5 and movably, a plurality of the welding connecting columns 602 are uniformly and movably arranged at the bottom of the heating part 601, and each of the welding connecting columns 602 connects the second sliding block 304 and the heating part 601 respectively; a plurality of the welding return springs 603 are correspondingly sleeved on the welding connecting columns 602, and each of the welding return springs 603 is connected between the heating part 601 and the second sliding block 304 respectively.

[0033] Further, the second trimming structure 8 includes a forming tool structure 801 and a plurality of tool connecting members 802; the forming tool structure 801 is disposed adjacent to the heating part 601, and the forming tool structure 801 is movably connected to the first trimming structure 7; a plurality of the tool connecting members 802 connect the forming tool structure 801 and the second sliding block 304 respectively.

[0034] Specifically, after the first cylinder structure 201 is started, it can drive the first telescopic rod 202 to extend or shorten, and then push the first sliding block 204 to reciprocate along the sliding guide frame 4 through the first connecting member 203. And the first connecting member 203 can be used to extend the action range of the first telescopic rod 202.

[0035] Similarly, the second cylinder structure 301 can also drive the second telescopic rod 302 to extend or shorten, and then drive the second sliding block 304 to reciprocate along the sliding guide frame 4.

[0036] Thus, when the foam material to be processed is in the welding process, the first sliding block 204 drives the crimping action structure 5 to press the material between the crimping action structure 5 and the heating part 601; at this time, the heating part 601 is powered on to start heating and weld the material, and the first trimming structure 7 is in the shape of a cutting tool, and it is not yet in contact connection with the forming tool structure 801 at this time. After that, the second cylinder structure 301 can drive the second sliding block 304 to move upward, so that the heating part 601 is pressed and retracted along the guide of the welding connection column 602, and the welding return spring 603 is compressed; and the forming tool structure 801 further moves upward to be connected to the first trimming structure 7, so that the welded foam material is trimmed and cut according to a preset shape. After the trimming is completed, each action mechanism resets, and the heating part 601 can also reset under the rebound of the welding return spring 603; thus, the next process flow can be entered.

[0037] In summary, a foam welding and trimming mechanism of the present invention is respectively provided with a frame 1, a first driving mechanism 2, a second driving mechanism 3, a sliding guide frame 4, a crimping action structure 5, a welding action structure 6, a first trimming structure 7 and a second trimming structure 8; the first driving mechanism 2 and the second driving mechanism 3 are respectively arranged on the side surface of the frame 1; the first driving mechanism 2 is arranged above the second driving mechanism 3; the sliding guide frame 4 is respectively connected to the first driving mechanism 2 and the second driving mechanism 3; the crimping action structure 5 and the welding action structure 6 are relatively movably arranged on the side surface of the frame 1, the first driving mechanism 2 is drivingly connected to the crimping action structure 5, and the second driving mechanism 3 is drivingly connected to the welding action structure 6; the first trimming structure 7 is connected to the first driving mechanism 2, and the second trimming structure 8 is connected to the second driving mechanism 3.
