DETAILED DESCRIPTION
[0021] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.
[0022] Refer to the instruction manual Figures 1 to 5 A scald-proof packaging bag heat sealing machine includes a heat sealing machine body 1 and a conveyor belt 3. The heat sealing machine body 1 is provided with a protective component 2, which is used to isolate the heat sealing machine body 1. The protective component 2 includes a fixed cover 21 and a movable cover 22. The fixed cover 21 is fixedly installed with the heat sealing machine body 1 and is installed on the top of the heat sealing machine body 1. The fixed cover 21 and the movable cover 22 are rotatably connected and installed on the outside of the heat sealing machine body 1. A mounting plate 25 is fixedly installed at the bottom of the heat sealing machine body 1. A bolt 23 is threadedly sleeved on the movable cover 22. A turntable is fixedly installed at the outer end of the bolt 23. 24. A threaded hole compatible with the bolt 23 is opened on the mounting plate 25. The bolt 23 can be rotated into the mounting plate 25 by rotating the turntable 24, so that the movable cover 22 can be fixed to prevent the movable cover 22 from being opened, and the heat sealing machine body 1 is isolated inside the protective cover, effectively preventing the staff from being scalded. When the heat sealing machine body 1 needs to be repaired, the turntable 24 is rotated to remove the bolt 23 from the fixed cover 21, and the movable cover 22 will no longer be fixed, and the movable cover 22 can be opened to expose the heat sealing machine body 1, which is convenient for maintenance personnel to repair.
[0023] It should be noted that the movable cover 22 is a multi-layer structure with a heat insulation layer in the middle for isolating the temperature. When the heat sealing machine body 1 is working, the temperature rises. By setting the movable cover 22 as a multi-layer structure with a heat insulation layer in the middle, the temperature can be effectively isolated, and the temperature of the surface of the protective cover can be prevented from rising, thereby further improving the safety of the device.
[0024] In this embodiment, the implementation scenario is specifically as follows: when sealing the packaging bag, the staff puts the packaging bag to be sealed on the conveyor belt, and makes the sealing part of the conveyor belt correspond to the heat sealer body 1. With the help of the conveyor belt 3 to transport the packaging bag, the part of the packaging bag to be sealed is input from the input end of the heat sealer body 1, and is output from the output end after heat sealing by the heat sealer body 1. Among them, the heat sealer body 1 is already a widely used sealing device, and its specific structure is not repeated in this embodiment. However, when the heat sealer body 1 is working, the temperature will greatly increase. At this time, a fixed cover 21 and a movable cover 22 are installed on the top and the outer side of the heat sealer body 1. The heat sealing machine body 1 is isolated and protected to prevent the staff from contacting the high-temperature heat sealing machine body 1 during operation, which effectively prevents the staff from being scalded during work. By rotating the turntable 24, the bolts 23 fix the movable cover 22 and the mounting plate 25 together, and then fix the movable cover 22 to prevent the movable cover 22 from being opened, thereby improving the safety of the device. When the heat sealing machine body 1 fails and needs maintenance, the turntable 24 is rotated to remove the bolts 23 from the mounting plate 25, and then the movable cover 22 is no longer fixed, and then the movable cover 22 can be opened to expose the heat sealing machine body 1, which is convenient for maintenance personnel to repair and simple and convenient to operate.
[0025] Furthermore, in order to prevent the rotating disk 24 from being misoperated by humans during use and the bolt 23 from being moved from the fixed cover 21, the present embodiment also provides the following technical solutions. Figure 4 and attached Figure 5 The protection component 2 also includes a first limiting component 4, which is used to limit the rotation of the bolt 23. The first limiting component 4 is connected to the bolt 23. The first limiting component 4 includes a mounting block 41 and a mounting disk 42. The mounting disk 42 and the mounting block 41 are threadedly connected to the bolt 23. The mounting disk 42 is fixedly mounted on the front side wall of the mounting block 41. The mounting block 41 is fixedly mounted on the front side wall of the movable cover 22. A ratchet 43 is fixedly mounted on the bolt 23. A fixed shaft 45 is fixedly mounted on the mounting disk 42. A pawl 44 is rotatably connected to the fixed shaft 45. The pawl 44 is adapted to the ratchet 43. A torsion spring 46 is fixedly connected to the bottom of the pawl 44. A slot is provided on the front side wall of the mounting disk 42, and one end of the torsion spring 46 is inserted into the slot.
[0026] It should be noted that when the turntable 24 is rotated, the bolt 23 moves inward and moves into the mounting plate 25, so that the mounting plate 25 and the movable cover 22 are fixed together. At this time, the turntable 24 drives the ratchet 43 to rotate, and the pawl 44 cooperates with the torsion spring 46 to limit the turntable 24. When the turntable 24 rotates in the opposite direction, the pawl 44 limits the ratchet 43 and the turntable 24. The advantage of such a setting is that after the fixed cover 21 is completely fixed, it is prevented from being touched by humans, so that the bolt 23 moves, resulting in the movable cover 22 not being fixed, thereby realizing the self-locking function and preventing human misoperation, so that the movable cover 22 cannot be opened, so that the heat sealing machine body 1 is isolated inside the protective cover, effectively preventing the staff from being scalded, and improving the safety of the device.
[0027] Furthermore, a second limiting assembly 5 for limiting the first limiting assembly 4 when the bolt 23 is released is provided on the mounting plate 42. The second limiting assembly 5 includes a limiting rod 51 and a limiting plate 52. The limiting plate 52 is fixedly mounted on the pawl 44. A limiting hole 53 matching the shape of the limiting rod 51 is penetrated through the top of the limiting plate 52. The limiting rod 51 is penetrated and installed on the mounting plate 42. A fixed plate 54 is fixedly installed on the limiting rod 51. A limiting spring 55 is sleeved on the surface of the limiting rod 51. The two ends of the limiting spring 55 are respectively fixedly mounted on the rear side wall of the fixing plate 54 and the front side wall of the mounting plate 42.
[0028] It should be noted that when it is necessary to open the movable hood 22, the pawl 44 is manually moved and the limit rod 51 is pulled until the pawl 44 is moved to the position of the limit hole 53 corresponding to the limit rod 51. In fact, the hand pulling the limit rod 51 is released, so that the limit hole 53 on the limit plate 52 slides into the limit rod 51, and the pawl 44 is limited by the limit rod 51, so that the pawl 44 releases the limit on the ratchet wheel 43, so that the turntable 24 can rotate in the opposite direction, and the bolt 23 is removed from the mounting plate 25, so that the movable hood 22 is no longer fixed together, and the movable hood 22 can be opened to expose the heat sealing machine body 1, which is convenient for maintenance personnel to repair. It has a simple structure, is easy to operate, and is easy to manufacture. It can prevent misoperation and does not affect the opening and closing of the movable hood 22.
[0029] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
