Description

Technical Field

[0001] This utility model relates to the field of sealing machines, and in particular to a heat sealing machine for waterproof mobile phone bags. Background Technology

[0002] A mobile phone pouch is a bag used to protect a mobile phone. During the production process, a sealing machine is used to seal the perimeter of the mobile phone pouch to complete the preparation. In the actual sealing operation, the sealing area is directly heated and mechanical pressure is applied to fuse the seal, thus completing the production of the mobile phone pouch.

[0003] In actual use, sealing machines usually directly press the sealing position. Before thermoforming, the plastic at the sealing position cannot be flattened, which easily leads to unevenness at the sealing position. During subsequent thermoforming, the plastic at the sealing position is prone to wrinkles, resulting in low sealing quality. In view of this, we propose a heat sealing machine for waterproof mobile phone bags. Summary of the Invention

[0004] To address the aforementioned shortcomings of existing technologies, this invention provides a heat-sealing machine for waterproof mobile phone bags. This effectively solves the problem that existing sealing machines typically directly press the sealing area without flattening the plastic before thermoforming, leading to unevenness at the sealing area. Consequently, during subsequent thermoforming, the plastic at the sealing area is prone to wrinkles, resulting in low-quality sealing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A heat-sealing machine for waterproof mobile phone bags includes a frame, with two sealing discs movably connected to the upper side of the frame, and overlapping plates elastically connected to both sides of the sealing discs.

[0007] In addition, a limiting plate fixedly connected to both sides of the frame, with a groove in the middle of the limiting plate; a clamping plate movably connected to the limiting plate, with a first inclined surface on the outer wall of the clamping plate, the first inclined surface slidingly engaging with a second inclined surface on the outer wall of the overlapping plate; and a heating strip fixedly installed on the outer wall of the top surface of the sealing plate located on the lower side.

[0008] Preferably, it also includes a frame fixedly installed on the outer wall of the sealing tray, the inner wall of the frame slidingly engaging with a slider fixedly installed on the outer wall of the sealing tray, and a first bladder being provided between the slider and the middle of the frame.

[0009] Preferably, it also includes a plurality of springs disposed between the middle of the two clamping plates, and a rubber layer is disposed on the outer wall of the clamping plates.

[0010] Preferably, it also includes a limiting groove with a symmetrical structure opened on the top surface of the upper sealing plate, a movable plate slidably connected in the limiting groove, a second bladder disposed between the middle of the two movable plates, the second bladder being connected to the first bladder through a connecting pipe, and a control valve being disposed on the connecting pipe.

[0011] Preferably, it also includes a rubber sheet arranged symmetrically on the bottom surface of the upper sealing plate, and the lower outer wall of the moving plate is in elastic contact with the rubber sheet, and the limiting groove is arranged with an inclined structure. When the two moving plates move away from each other, the corresponding rubber sheet will deform and squeeze the bag.

[0012] Preferably, it also includes a drive rod movably connected to the outer wall of the limiting plate, the inner end of the drive rod extending through the limiting plate into the groove.

[0013] Preferably, it also includes a drive shaft fixedly connected to the outer wall of the sealing disc for adjusting the distance between the two sealing discs.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This invention utilizes the sliding fit between the overlapping plate and the clamping plate to clamp the bag and move it to both sides before sealing, keeping the bag in a taut state and ensuring the flatness of the sealing position, thereby guaranteeing the sealing quality.

The basic principles of the invention defined in the following description can be used in other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the invention.

[0030] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number. Example

[0031] See attached document Figure 1-4As shown, a heat-sealing machine for waterproof mobile phone bags includes a frame 100, with two sealing discs 200 movably connected to the upper side of the frame 100, and overlapping plates 300 elastically connected to both sides of the sealing discs 200. Specifically, in this application, the two sealing discs 200 are configured to adjust their relative positions, and a heating strip 210 is fixedly installed on the outer wall of the top surface of the sealing disc 200 located on the lower side. When the two sealing discs 200 are in an overlapping state, the bag located in the middle of the two sealing discs 200 can be heated by the heating strip 210 and sealed.

[0032] Furthermore, it also includes a drive shaft 240 fixedly connected to the outer wall of the sealing disc 200, used to adjust the distance between the two sealing discs 200. The drive shaft 240 is fixedly connected to the output end of an external hydraulic cylinder. Driven by the external hydraulic cylinder, the position between the two sealing discs 200 is adjusted. A heating strip 210 located on the lower sealing disc 200 is used to seal the edge of the bag.

[0033] To ensure the quality of the sealing position when the bag is sealed and to avoid poor sealing quality caused by bag wrinkles, this application also includes a limiting plate 110 fixedly connected to both sides of the frame 100, a groove 111 is provided in the middle of the limiting plate 110, and a clamping plate 400 is movably connected to the limiting plate 110. A first inclined surface 401 is provided on the outer wall of the clamping plate 400, and the first inclined surface 401 slides and engages with a second inclined surface 301 provided on the outer wall of the overlapping plate 300. Specifically, during the sealing stage, when the two sealing discs 200 approach each other, the overlapping plates 300 elastically connected to the sides of the sealing discs 200 will also move synchronously. Combined with the sliding fit between the second inclined surface 301 on the overlapping plate 300 and the first inclined surface 401 on the outer wall of the clamping plate 400, before sealing, the two clamping plates 400 can clamp the edge of the bag. As the sealing discs 200 continue to approach, the clamping plates 400 can effectively clamp the edge of the bag. Furthermore, combined with the sliding fit between the first inclined surface 401 and the second inclined surface 301, the two clamping plates 400 in the clamping state, under the action of the inclined surface fit, will drive the bag to move away from the sealing discs 200, thereby flattening the bag and ensuring the flatness of the sealing position on the bag, thus guaranteeing the subsequent sealing quality.

[0034] To better understand this solution, the positional changes of the overlapping plate 300 and the clamping plate 400 during sealing are explained. Specifically, when the two sealing discs 200 approach each other under the action of the external drive shaft 240, the overlapping plate 300 moves along the outer wall of the limiting plate 110, and at the same time, the clamping plate 400 is also restricted by the limiting plate 110, and its position is adjusted only vertically in sync with the overlapping plate 300. During this stage, there is no relative sliding between the first inclined surface 401 and the second inclined surface 301. As the overlapping plates on the upper and lower sides... When the plates 300 approach each other, and the two clamping plates 400 move to the groove 111, the limiting plate 110 cancels the restriction effect on the clamping plates 400. Under the sliding fit between the first inclined surface 401 and the second inclined surface 301, the clamping plates 400 in the groove 111 will move outward. At this time, the clamping plates 400 located on the upper and lower sides have achieved stable clamping of the bag edge. In this case, when the clamping plates 400 move outward, the corresponding bag will be stretched, so that the bag at the sealing position is in a flat state, ensuring the subsequent sealing quality.

[0035] Regarding the reset phase, this application also includes multiple springs 410 disposed between the middle portions of the two clamping plates 400, with a rubber layer disposed on the outer wall of the clamping plate 400. It also includes a drive rod 112 movably connected to the outer wall of the limiting plate 110, with the inner end of the drive rod 112 extending through the limiting plate 110 into the groove 111. First, the drive shaft 240 is used to move the two sealing discs 200 away from each other. Simultaneously, the drive rod 112 pushes the two clamping plates 400 in the groove 111 out of the groove 111. Under the action of the springs 410, the two clamping plates 400 will reset.

[0036] This application also includes a frame 220 fixedly installed on the outer wall of the sealing tray 200. The inner wall of the frame 220 is slidably engaged with a slider fixedly installed on the outer wall of the sealing tray 200, and a first bladder 221 is provided between the slider and the middle of the frame 220. It also includes symmetrically arranged limiting grooves 201 located on the top surface of the upper sealing tray 200. A movable plate 231 is slidably connected within the limiting groove 201. A second bladder 230 is provided between the middle of the two movable plates 231. The second bladder 230 is connected to the first bladder 221 through a connecting pipe 232, and a control valve is provided on the connecting pipe 232. As mentioned above, the bag body is clamped at the edge by the clamping plate 400 and moved to both sides, so that the bag body can be in a state with a certain degree of tension. However, in this process, it is necessary to ensure that there is not too much air inside the bag body. Therefore, in this application, through the connection between the first bladder 221 and the second bladder 230, when the two overlapping plates 300 approach each other, the first bladder 221 set in the frame 220 will be compressed. When the upper and lower sides of the bag body are in a close fit, the control valve set on the connecting pipe 232 opens, and the gas in the first bladder 221 enters the interior of the second bladder 230, which in turn drives the moving plate 231 to slide in the limiting groove 201.

[0037] Furthermore, this application also includes rubber sheets 500 symmetrically arranged on the bottom surface of the upper sealing plate 200, with the lower outer wall of the moving plate 231 in elastic contact with the rubber sheet 500. The limiting groove 201 is inclined. When the two moving plates 231 move away from each other, the corresponding rubber sheet 500 deforms and squeezes the bag. When the moving plate 231 slides in the limiting groove 201, due to the inclined structure of the limiting groove 201, when the moving plate 231 moves from the inside to the outside, the corresponding moving plate 231 will tilt downwards, which can be understood as a downward tendency in the vertical direction. At this time, the bottom outer wall of the moving plate 231 will squeeze the rubber sheet 500, the rubber sheet 500 will squeeze the outer wall of the bag, and the air in the middle of the two bags in the upper and lower positions will be discharged, ensuring that the bag can be stably sealed.

The objectives of the present invention have been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments, and any modifications or variations of the embodiments of the present invention may be made without departing from the stated principles.
