DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the utility model will be apparently and completely described in connection with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the ordinary skilled in the art without any creative labor belong to the scope of protection of the utility model.

[0026] As Figures 1-4 , 8-10, the utility model provides a kind of ultrasonic heat sealing machine, including rack 1, ultrasonic generator is equipped in rack 1, lifting rod is equipped on rack 1, the telescopic end of lifting rod is driven with flower wheel, the side of rack 1 is fixed with conveying belt 2, both sides of conveying belt 2 are equipped with baffle 3, baffle 3 upper end close to rack 1 is fixed with left support plate 4, left support plate 4 is placed below flower wheel, left support plate 4 is equipped with alignment slot 5 close to one end of incoming material, mirror image is equipped with alignment device in the upper and lower ends of alignment slot 5, alignment device all includes connecting plate 6, the side of connecting plate 6 close to conveying belt 2 is equipped with U-shaped support 7, the opening end of support 7 is towards alignment slot 5, the side wall of support 7 is equipped with long circular hole 9 perpendicular to left support plate 4, connecting rod 10 is equipped in long circular hole 9, connecting rod 10 is slid along long circular hole 9 by lifting device, alignment wheel 11 is sleeved on connecting rod 10 in support 7, alignment wheel 11 is driven by driving device 12, the tangent direction of two alignment wheels 11 mutually close to one end all is towards connecting plate 6, guiding wheel 13 is equipped on the side of connecting plate 6 away from flower wheel.

[0027] In use, the filter core raw material to be pressed is placed on the conveyor belt 2, and the two ends of the filter core raw material that need to be connected are fitted between the guide wheel 13 and the left support plate 4. The guide wheel 13 can guide the filter core raw material to smoothly enter between the two alignment wheels 11 at the alignment slot 5, and prevent the alignment wheels 11 from scratching the filter core raw material, further enhancing the adaptability of the device. If the end of the filter core raw material needs to be aligned, the lifting device controls the connecting rod 10 to slide along the long circular hole 9, thereby controlling the two alignment wheels 11 at both ends of the alignment slot 5 to move closer to each other, and the driving device 12 controls the two alignment wheels 11 to rotate relative to each other. The alignment wheels 11 apply a friction force to the filter core raw material, causing the end of the filter core raw material to abut against the connecting plate 6, ensuring that the end of the filter core raw material is accurately aligned, improving the pressing quality. After alignment, the lifting device can separate the alignment wheels 11 from each other, thereby allowing the filter core raw material to pass through. The lifting device can be operated intermittently to make the end alignment process of the filter core raw material more stable and controllable, reducing the need for monitoring the state of the filter core raw material. When the end of the filter core raw material is aligned, the conveyor belt 2 moves the filter core raw material through the flower wheel, and the ultrasonic generator causes the end of the filter core raw material to be stitched through the flower wheel. The ultrasonic generator and the flower wheel are both prior art. The conveyor belt 2 is provided with a baffle 3 on both sides to prevent the filter core raw material from falling or deviating during transmission, improving the safety performance of the device.

[0028] As shown in Figure 1 、 4 -7, the baffle 3 on the side of the conveyor belt 2 away from the rack 1 is fixed with a right support plate 14. The left support plate 4 and the right support plate 14 are symmetrically provided with notches connected by an arc-shaped slide rail 15.

The air suction chamber 16 has a feeding wheel 17 rotating at the air inlet, which is driven by a micro motor. The air inlet of the air suction chamber 16 is connected to a silica gel tube 18. The air suction chamber 16, micro motor, slide rail motor and arc-shaped slide rail 15 are all prior art.

[0029] In order to reduce the manual folding of the filter material, during use, the two ends of the filter material are placed on the left support plate 4 and the right support plate 14, and the slide rail motor moves to the lower side of the gap of the right support plate 14 through the arc-shaped slide rail 15. When the filter material passes, start the suction chamber 16, and the suction chamber 16 fixes the end of the filter material. At the same time, the slide rail motor drives the suction chamber 16 to move to the left support plate 4, realizing the automatic folding of the filter material, significantly reducing the steps of manual folding of the filter material, and improving the production efficiency. Then the micro motor driven feeding wheel 17 can feed the filter core. When the feeding speed of the feeding wheel 17 is the same as that of the conveying belt 2, it can prevent the filter material from deviating, ensuring the accuracy and continuity of feeding. When the feeding of a single filter material is completed, the suction chamber 16 is quickly reset through the arc-shaped slide rail 15 and the slide rail motor, waiting for the next operation. By setting the silica gel pipe 18, the sealing performance of the suction chamber 16 can be improved, ensuring that the suction chamber 16 can generate enough suction force when fixing the filter material, preventing the filter material from sliding or moving during folding. And when feeding, the elastic deformation characteristics of the silica gel pipe 18 can facilitate the contact between the feeding wheel 17 and the filter material.

[0030] As shown in Figures 8-10 , the driving device 12 includes a driving motor 20, and the side wall of the connecting plate 6 is provided with a through hole 19. One end of the alignment wheel 11 is fixedly connected with a chain wheel 21, and the driving motor 20 is connected with the chain wheel 21 through the through hole 19 and the chain. Because the chain has a certain flexibility, it can adapt to the possible slight displacement or inclination of the alignment wheel 11 during lifting, thereby ensuring the continuity and stability of the driving force. The combination structure of the chain wheel 21 and the chain is relatively simple, easy to install and maintain. The chain transmission has high transmission efficiency, which helps to ensure that the alignment wheel 11 can respond quickly when needed, thereby realizing the rapid alignment of the filter material. The transmission mode of the chain wheel 21 and the chain is relatively stable, which can reduce the noise and vibration generated by the equipment during operation.

[0031] As shown in Figure 5 , 8-10, the lifting device includes two limiting rods 22 penetrating through both ends of the connecting rod 10 respectively, springs are sleeved on the limiting rods 22, a limiting plate 23 is arranged at one end of the limiting rod 22 below the connecting rod 10, the top end of the limiting rod 22 penetrates through the support 7, gears 24 corresponding to the limiting rods 22 are rotatably arranged on the support 7, the limiting rods 22 penetrate through the gears 24, the limiting rods 22 are screwed with the gears 24, a rack 25 is slidably arranged at the top end of the support 7, the two ends of the rack 25 on the same side are engaged with the gears 24 on the two limiting rods 22 respectively, and the middle part of the rack 25 is engaged with a lifting motor 26. The lifting motor 26 is a prior art. In use, the lifting motor 26 drives the gears 24 to rotate through the rack 25, the gears 24 drive the limiting rods 22 to lift through the screwing with the limiting rods 22, and the limiting rods 22 drive the connecting rod 10 to slide along the long circular hole 9 through the limiting plate 23 and the springs, so that the alignment wheel 11 can accurately reach the required position in the lifting process, and the accurate alignment of the filter core raw material is realized. The springs can absorb and buffer the generated vibration and impact force, so that the stability of the lifting movement is maintained, and the limiting plate 23 ensures that the limiting rod 22 will not be separated from the support 7 in the lifting process, and the stability of the lifting device is further enhanced.
