Description

Technical Field

[0001] The utility model relates to the field of fabric bonding devices, in particular to a fabric bonding device with double-sided hot pressing. Background Art

[0002] With the continuous development of technology, technicians gradually adopt the method of hot melt adhesive pasting to achieve seamless connection of fabrics, and this process is specifically realized through seamless equipment. When the seamless equipment operates, the heated hot melt adhesive tape needs to be conveyed between two pressing wheels, and the hot melt adhesive tape and the fabric are pressed together by the pressure applied by the two pressing wheels, so as to realize the bonding and fixing of the two fabrics by the hot melt adhesive tape.

[0003] Generally, the seamless equipment heats the hot melt adhesive tape by conveying it through a heat conducting member before it enters the two pressing wheels, and the hot melt adhesive tape is heated by contacting the heat conducting member. This method only heats one side of the hot melt adhesive tape that contacts the heat conducting member, with low heating efficiency. Moreover, the method of heating the hot melt adhesive tape first and then pressing it will undoubtedly cause a certain amount of heat energy loss before the hot melt adhesive tape is conveyed to be pressed, which is relatively energy wasteful. Content of the Utility Model

[0004] In view of the deficiencies in the above-mentioned background art, the utility model provides a fabric bonding device with double-sided hot pressing.

[0005] The utility model adopts the following technical scheme:

[0007] A machine base, a fixed frame is arranged under the machine base, and a lifting frame is arranged on the machine base;

[0008] A hot pressing mechanism, the hot pressing mechanism includes a conveyor belt, a driving wheel and a heat conducting member, the heat conducting member generates high temperature, both the fixed frame and the lifting frame fix the heat conducting member, several rotatable driving wheels are connected to the sides of both the fixed frame and the lifting frame, and the conveyor belt is connected to the outside of the driving wheels on the side of the fixed frame and the outside of the driving wheels on the side of the lifting frame, and the driving wheels rotate to drive the conveyor belt to operate; wherein,

[0009] In the fixed frame, the conveyor belt bypasses the upper surface of the heat conducting member, so that an upper conveying surface is formed on the conveyor belt located on the heat conducting member;

[0010] In the lifting frame, the conveyor belt bypasses the lower surface of the heat conducting member, so that a lower conveying surface is formed under the conveyor belt located under the heat conducting member; the lifting frame presses down to the fixed frame, so that the lower conveying surface presses against the upper conveying surface.

[0011] In a possible implementation, the hot pressing mechanism further includes a tension pulley, a swing rod, and a tension spring. One end of the swing rod is rotatably connected to the fixed frame, the tension pulley is rotatably connected to the other end of the swing rod, the conveyor belt bypasses the tension pulley, and both ends of the tension spring are respectively connected to the swing rod and the fixed frame. Moreover, the elastic force generated by the compression of the tension spring pulls the tension pulley in a direction away from the heat conducting member.

[0012] In a possible implementation, the hot pressing mechanism further includes a tension pulley, a swing rod, and a tension spring. One end of the swing rod is rotatably connected to the lifting frame, the tension pulley is rotatably connected to the other end of the swing rod, the conveyor belt bypasses the tension pulley, and both ends of the tension spring are respectively connected to the swing rod and the lifting frame. Moreover, the elastic force generated by the compression of the tension spring pulls the tension pulley in a direction away from the heat conducting member.

[0013] In a possible implementation, both sides of the heat conducting member are respectively a flat surface and an arc surface. In the heat conducting member of the fixed frame, the lower end of the heat conducting member is the arc surface, and the upper end of the heat conducting member is the flat surface.

The conveyor belt bypasses the flat surface and the arc surface, so that a lower conveying surface is formed on the conveyor belt located under the flat surface.

[0015] In a possible implementation, a lifting cylinder is fixed to the upper end of the machine base, and the lifting frame is fixed to the telescopic rod of the lifting cylinder.

[0016] As can be seen from the above description of the structure of the present utility model, compared with the prior art, the present utility model has the following advantages: When operating, two pieces of fabric are placed on the upper conveying surface, and a hot melt tape is pasted between the two pieces of fabric. By lowering the lifting frame until the lower conveying surface presses against the upper conveying surface, the heat conducting member of the lifting frame can press the lower conveying surface against the two pieces of fabric and press the hot melt tape against the heat conducting member of the fixed frame. The two heat conducting members can heat both sides of the hot melt tape, enabling the hot melt tape to be evenly heated and melted to achieve the adhesion of the two pieces of fabric. Moreover, during this heating process, the two conveyor belts can simultaneously convey the adhered fabric, realizing the output of the fabric that has completed adhesion. Thus, it can be seen that during the working process of the present utility model, the heat conducting members of the fixed frame and the lifting frame respectively heat both sides of the hot melt tape simultaneously, which is beneficial to improving the heating efficiency of the hot melt tape. And while heating the hot melt tape, the fabric and the hot melt tape are pressed and conveyed, avoiding heat energy loss caused by heating first and then pressing. Brief Description of the Drawings

It should be understood that these directional terms are relative concepts, which are used for relative description and clarification and may change accordingly with the change of the orientation in which the components in the drawings are placed.

[0026] The present utility model provides a fabric bonding device for double-sided hot pressing. As shown in the attached drawings Figure 1 and 4 , the device includes a machine base 2 and a hot pressing mechanism. Among them, the machine base 2 can be fixed on a workbench 1, and a fixing frame 21 is provided under the machine base 2, and a lifting frame 22 is provided on the machine base 2. The fixing frame 21 is fixed to the machine base 2, and the lifting frame 22 is connected to the machine base 2 and vertically lifts relative to the fixing frame 21. Further, a lifting cylinder 23 is fixed to the upper end of the machine base 2, and the lifting frame 22 is fixed to the telescopic rod of the lifting cylinder 23. By vertically extending and retracting the telescopic rod of the lifting cylinder 23, the lifting frame 22 can be driven to vertically lift relative to the fixing frame 21.

[0027] As shown in the attached drawings Figures 2 to 4As shown, both the fixed frame 21 and the lifting frame 22 are provided with hot pressing mechanisms. The hot pressing mechanism includes a conveyor belt 31, a driving wheel 32, and a heat conducting member 33. Among them, both the fixed frame 21 and the lifting frame 22 are fixed with the heat conducting member 33. A heating module can also be fixed in the machine base 2. The heating module converts electrical energy into heat energy and transfers it to the heat conducting member 33 to make the heat conducting member 33 generate high temperature. A number of rotatable driving wheels 32 are connected to the sides of both the fixed frame 21 and the lifting frame 22 where the heat conducting member 33 is fixed. The connection structure can be that the driving wheel 32 is embedded with a bearing, the inner ring of the bearing is sleeved and fixed on a rotating shaft, and the end of the rotating shaft away from the bearing is helically connected and fixed to the side of the fixed frame 21 or the side of the lifting frame 22, so that the driving wheel 32 is restricted to rotate around the rotating shaft on the side of the fixed frame 21 or the lifting frame 22. While the conveyor belt 31 bypasses the heat conducting member 33, it also bypasses the driving wheels 32 on the side of the heat conducting member 33, so that when the driving wheel 32 rotates, it drives the conveyor belt 31 to run relative to the heat conducting member 33.

[0028] Further, the two sides of the heat conducting member 33 are respectively a flat surface 331 and an arc surface 332. Among them, the lower end of the heat conducting member 33 of the fixed frame 21 is the arc surface 332, and the upper end is the flat surface 331. And the conveyor belt 31 bypasses the flat surface 331 and the arc surface 332, so that an upper conveying surface 311 is formed on the conveyor belt 31 located on the flat surface 331. The lower end of the heat conducting member 33 of the lifting frame 22 is the flat surface 331, and the upper end is the arc surface 332. And the conveyor belt 31 bypasses the flat surface 331 and the arc surface 332, so that a lower conveying surface 312 is formed on the conveyor belt 31 located below the flat surface 331. In this structure, the upper conveying surface 311 and the lower conveying surface 312 are used to press and convey the fabric 4, and the contact between the conveyor belt 31 and the two sides of the heat conducting member 33 can fully increase the contact area between the conveyor belt 31 and the heat conducting member 33, which is beneficial to making the conveyor belt 33 receive heat more fully, thereby improving the heat conduction efficiency of the fabric 4 through the conveyor belt 33.

[0029] Continue to refer to the appendix Figure 3 and 4, the hot pressing mechanism further includes a tension wheel 34, a swing rod 35, and a tension spring 36. One end of the swing rod 35 is connected to the fixed frame 21 for rotation. The connection structure can be that a bolt passes through the swing rod 35 and the fixed frame 21 and is screwed tightly to fix, so that the swing rod 35 rotates relative to the fixed frame 21 with the bolt as the axis. The tension wheel 34 is connected to the other end of the swing rod 35 for rotation. The connection structure can be that a bearing is embedded and fixed in the tension wheel 34, the inner ring of the bearing fixes the rotating shaft, and the rotating shaft is screwed to the swing rod 35 to limit the tension wheel 34 to rotate at one end of the swing rod 35. The conveyor belt 31 bypasses the tension wheel 34 so that the tension wheel 34 is within the range of the conveyor belt 31. The two ends of the tension spring 36 are respectively connected to the swing rod 35 and the fixed frame 21. Preferably, hooks are provided at both ends of the tension spring 36, and both the fixed frame 21 and the swing rod 35 are fixedly connected with pins. The two ends of the tension spring 36 are respectively hooked on the two pins to achieve the connection. In this structure, the elastic force generated by the compression of the tension spring 36 is used to pull the tension wheel 34 in a direction away from the heat conducting member 33, so as to pull the conveyor belt 31 of the fixed frame 21 to be tightened and closely attached to the surface of the heat conducting member 33, which is beneficial to improving the heat transfer efficiency of the conveyor belt 31 and can prevent the conveyor belt 31 from being too loose to maintain the transmission efficiency of the conveyed fabric 4.

[0030] Similarly to the above-mentioned fixed frame 21 provided with the tension wheel 34, the swing rod 35, and the tension spring 36, the lifting frame 22 is also connected with the tension wheel 34, the swing rod 35, and the tension spring 36. Specifically, one end of the swing rod 35 is connected to the lifting frame 22 for rotation, the other end of the swing rod 35 is connected to the tension wheel 34, the conveyor belt 31 bypasses the tension wheel 34, and the two ends of the tension spring 36 are respectively connected to the swing rod 35 and the lifting frame 22. The elastic force generated by the compression of the tension spring 36 is used to pull the tension wheel 34 in a direction away from the heat conducting member 33, so as to pull the conveyor belt 31 of the lifting frame 22 to be tightened and closely attached to the surface of the heat conducting member 33, which is beneficial to improving the heat transfer efficiency of the conveyor belt 31 and can prevent the conveyor belt 31 from being too loose to maintain the transmission efficiency of the conveyed fabric 4.

[0031] Drive motors 37 are fixed on the other sides of both the fixed frame 21 and the lifting frame 22. Among them, rotatable transmission shafts are connected inside both the fixed frame 21 and the lifting frame 22. One end of the transmission shaft passes out of the fixed frame 21 and is fixedly connected to the transmission wheel 32, and the other end of the transmission shaft is in transmission connection with the drive motor 37. The transmission connection structure can be transmission through a synchronous belt and synchronous wheels to change the transmission ratio of the drive motor 37 driving the transmission wheel 32 to rotate, thereby reducing the rotational speed of the transmission wheel, so as to achieve the drive motor 37 driving the transmission wheel 32 and the conveyor belt 31 to operate smoothly.

[0032] Furthermore, the utility model further includes a control system and a synchronizer. The control system can be a PLC controller, which is used to control the driving motor 37, the heating module and the lifting cylinder 23 to work. The synchronizer is an encoder, which is fixed on the side of the transmission shaft and is used to sense the rotation of the transmission wheel 32 connected to the fixed frame 21, so as to sense the running speed of the conveyor belt 31 of the fixed frame 21. The synchronizer is also signal-connected to the control system to send the rotation speed data of the transmission shaft to the control system, so that the control system controls the driving motor 37 fixed to the lifting frame 22 to drive the transmission wheel 32 of the lifting frame 22 to rotate at the same speed, so that the conveyor belt 31 of the lifting frame 22 and the conveyor belt 31 of the fixed frame 21 run at the same running speed and in opposite directions, and can pull the pressed fabric 4 and the hot melt tape 41 to be conveyed forward smoothly.

[0033] During operation, as shown in the Figure 6 accompanying drawings, place two pieces of fabric 4 on the upper conveying surface 312, and paste the hot melt tape 41 between the two pieces of fabric 4. Then lower the lifting frame 22 until the lower conveying surface 311 presses against the upper conveying surface 312, so that the heat conducting member 33 of the lifting frame 22 presses the two pieces of fabric 4 and the hot melt tape 41 against the heat conducting member 33 of the fixed frame 21. The two heat conducting members 33 can evenly heat both sides of the hot melt tape 41, so that the hot melt tape 41 is heated and melted to realize the bonding of the two pieces of fabric 4. During this heating process, the two conveyor belts 31 can convey the bonded fabric 4 at the same time, realizing the output of the bonded fabric 4. It can be seen that the utility model can continuously convey the fabric 4 through the conveyor belt 31 of the fixed frame 21 and the conveyor belt 31 of the lifting frame 22. During the process, the heat conducting member 33 of the fixed frame 21 and the heat conducting member 33 of the lifting frame 22 respectively heat both sides of the hot melt tape 41 at the same time, which is beneficial to improving the heating efficiency of the hot melt tape 41, and pressing and conveying the fabric 4 and the hot melt tape 41 while heating the hot melt tape 41, avoiding the heat energy loss caused by heating first and then pressing.

[0034] The above is only the specific embodiment of the utility model, but the design concept of the utility model is not limited thereto. Any non-substantial modification made to the utility model using this concept shall belong to the act of infringing the protection scope of the utility model.
