Description

Technical Field

[0001] This utility model relates to the field of vacuum packaging machine technology, specifically a heat sealing device for a vacuum packaging machine. Background Technology

[0002] Vacuum packaging machines are mechanical devices that remove air from packaging bags and seal them. Their core purpose is to create a low-oxygen or oxygen-free packaging environment, thereby effectively extending the shelf life of food, medicine, electronic products, and other items, and providing protection.

[0003] Vacuum packaging machines preserve goods through two main steps: vacuuming and heat sealing. The heat sealing device is the core component, and its performance directly determines the sealing and preservation effect of the packaging. Existing heat sealing devices are usually heating strips made of electric heating elements. However, existing heat sealing devices are mostly fixed with multiple screws, which makes the disassembly process cumbersome, the downtime is long, and it will affect production efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a heat sealing device for a vacuum packaging machine, so as to solve the problem mentioned in the background art that the existing heat sealing devices mostly use multiple screws for fixing, the disassembly process is cumbersome, the downtime is long, and the production efficiency is affected.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heat-sealing device for a vacuum packaging machine, comprising:

[0006] The machine body, including the vacuum packaging machine itself;

[0007] The disassembly mechanism includes a mounting base, which is fixedly connected to the surface of the vacuum packaging machine body. A mounting block is slidably connected to the surface of the mounting base. A heat-sealing strip is fixedly connected to the upper surface of the mounting block. A fixing block is fixedly connected to the surface of the mounting base. A spring is fixedly connected to the inner surface of the fixing block. A connecting piece is fixedly connected to the surface of the spring. An insertion rod is fixedly connected to the side of the connecting piece away from the spring. A pull rod is fixedly connected to the side of the connecting piece away from the insertion rod.

[0008] Preferably, the compensation mechanism includes a mounting bolt threaded onto the surface of the mounting base, a mounting plate movably connected to the surface of the mounting bolt, and a silicone thermal pad fixedly connected to the surface of the mounting plate.

[0009] Preferably, the mounting bases are symmetrically distributed in four groups on the surface of the vacuum packaging machine body, and the heat sealing strip is slidably connected to the mounting block and the mounting base.

[0010] Preferably, the two ends of the spring are fixedly connected to the fixing block and the connecting piece, respectively, and the connecting piece is slidably connected to the fixing block through the spring.

[0011] Preferably, the insertion rod is connected by a connecting piece and a mounting block, and the pull rod is slidably connected by a connecting piece and a fixing block.

[0012] Preferably, four sets of mounting bolts are symmetrically distributed on the surface of one set of mounting bases, and the mounting plate is movably connected to the mounting base through the mounting bolts.

[0013] Preferably, the silicone thermal pad is movably connected via a mounting plate and a heat-sealing strip.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. Through the sliding connection between the mounting base and the mounting block, the fixed connection between the mounting block and the heat sealing strip, the fixed connection between the mounting base and the fixing block, the fixed connection between the fixing block and the spring, the fixed connection between the spring and the connecting piece, the fixed connection between the connecting piece and the insert rod, and the fixed connection between the connecting piece and the pull rod, pulling the pull rod causes the insert rod to move backward, causing the insert rod to disengage from the mounting block. This releases the locking of the mounting block and the heat sealing strip, allowing the mounting block and the heat sealing strip to slide off the mounting base for disassembly. This facilitates the disassembly, maintenance, and replacement of the heat sealing strip by the operators, shortens downtime, and improves production efficiency.

[0016] 2. The mounting base and mounting bolts are connected by threads, the mounting bolts and mounting plate are connected by movable connections, and the mounting plate and silicone thermal pad are connected by fixed connections. The silicone thermal pad has good thermal conductivity and elasticity, and can deform under heat sealing pressure, thereby effectively compensating for unevenness caused by various reasons, ensuring uniform pressure in the heat sealing area, sufficient heat transfer, eliminating false sealing and leakage, and greatly improving the sealing strength and consistency of the seal. Moreover, the mounting bolts make the silicone thermal pad removable, which makes it convenient for staff to remove and replace the silicone thermal pad. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 One embodiment provided by this utility model:

[0025] A heat sealing device for a vacuum packaging machine, comprising:

[0026] The machine body includes the vacuum packaging machine body 1, which is used to vacuum package the packaging bag. The vacuum packaging machine body 1 is an existing product and is not a technical protection point of this application. It will not be described in detail here.

[0027] The disassembly mechanism includes a mounting base 2, which is fixedly connected to the surface of the vacuum packaging machine body 1. The mounting base 2 is used to install the mounting block 21 and the heat sealing strip 22 onto the vacuum packaging machine body 1. The mounting block 21 is slidably connected to the surface of the mounting base 2. The mounting block 21 is used to install the heat sealing strip 22 onto the mounting base 2, thereby limiting the vertical movement of the heat sealing strip 22. The heat sealing strip 22 is fixedly connected to the upper surface of the mounting block 21. The heat sealing strip 22 is used to heat seal the packaging bag. The heat sealing strip 22 is an existing product and is not considered a technical protection point of this application, so it will not be described in detail here. A fixing block 23 is fixedly connected to the surface of the mounting base 2. The fixing block 23 is used to fix the locking mechanism onto the mounting base 2. A spring 24 is fixedly connected to the inner surface of the fixing block 23. The spring 24 is used to apply external force to the connecting piece 25 and the insert rod 26, causing the insert rod 26 to insert into the mounting block 21, thereby locking the mounting block 21 and the heat sealing strip 22 and installing the heat sealing strip 22 onto the mounting base 2. The surface of spring 24 is coated with damping material to prevent the spring 24 from bouncing back and forth and causing the locking of the mounting block 21 and heat seal strip 22 to loosen. A connecting piece 25 is fixedly connected to the surface of spring 24. The connecting piece 25 is used to connect spring 24, insert rod 26 and pull rod 27, and also to compress spring 24, causing spring 24 to deform. The insert rod 26 is fixedly connected to the side of connecting piece 25 away from spring 24. The insert rod 26 is used to insert into the mounting block 21, thereby realizing the locking of the mounting block 21 and heat seal strip 22. The heat sealing strip 22 is locked by installing it on the mounting base 2. A pull rod 27 is fixedly connected to the side of the connecting piece 25 away from the insertion rod 26. The pull rod 27 is used to pull the insertion rod 26 backward, so that the insertion rod 26 is separated from the mounting block 21. This can release the locking of the mounting block 21 and the heat sealing strip 22, and enable the disassembly of the mounting block 21 and the heat sealing strip 22. This makes it convenient for workers to disassemble the heat sealing strip 22 for maintenance and replacement, shortens downtime, and improves production efficiency.

[0028] Furthermore, the compensation mechanism includes mounting bolts 3, which are threaded onto the surface of the mounting base 2. Mounting bolts 3 are used to mount the mounting plate 31 and the silicone thermal pad 32 onto the mounting base 2, while also enabling the silicone thermal pad 32 to be detachable, facilitating its replacement by operators. The mounting plate 31 is movably connected to the surface of the mounting bolts 3, and is used to mount the silicone thermal pad 32 onto the mounting base 2. The silicone thermal pad 32 is fixedly connected to the surface of the mounting plate 31. The silicone thermal pad 32 has good thermal conductivity and elasticity, and can deform under heat-sealing pressure, effectively compensating for unevenness caused by various reasons, ensuring uniform pressure in the heat-sealing area, sufficient heat transfer, eliminating false sealing and leakage, and significantly improving the sealing strength and consistency of the seal. The silicone thermal pad 32 is an existing product and is not considered a technical protection point of this application; therefore, it will not be described in detail here.

[0029] Furthermore, the mounting bases 2 are symmetrically distributed in four groups on the surface of the vacuum packaging machine body 1. The mounting bases 2 are used to install the mounting blocks 21 and the heat sealing strips 22 on the vacuum packaging machine body 1. The mounting blocks 21 are used to install the heat sealing strips 22 on the mounting bases 2 to limit the vertical movement of the heat sealing strips 22. The heat sealing strips 22 are slidably connected to the mounting blocks 21 and the mounting bases 2. The heat sealing strips 22 are used to heat seal the packaging bags. The heat sealing strips 22 are existing products and are not considered as a technical protection point of this application. Therefore, they will not be described in detail here.

[0030] Furthermore, the fixing block 23 is used to fix the locking mechanism on the mounting base 2. The two ends of the spring 24 are fixedly connected to the fixing block 23 and the connecting piece 25 respectively. The spring 24 is used to apply external force to the connecting piece 25 and the insert rod 26, so that the insert rod 26 is inserted into the mounting block 21, thereby locking the mounting block 21 and the heat sealing strip 22 and installing the heat sealing strip 22 on the mounting base 2. The surface of the spring 24 is coated with damping material to prevent the spring 24 from jumping back and forth and causing the locking of the mounting block 21 and the heat sealing strip 22 to loosen. The connecting piece 25 is slidably connected to the fixing block 23 through the spring 24. The connecting piece 25 is used to connect the spring 24, the insert rod 26 and the pull rod 27, and at the same time to compress the spring 24, causing the spring 24 to deform.

[0031] Furthermore, the insertion rod 26 is connected to the mounting block 21 via the connecting piece 25. The insertion rod 26 is inserted into the mounting block 21, thereby locking the mounting block 21 and the heat sealing strip 22 and installing the heat sealing strip 22 on the mounting base 2. The pull rod 27 is slidably connected to the fixing block 23 via the connecting piece 25. The pull rod 27 is used to pull the insertion rod 26 backward, causing the insertion rod 26 to disengage from the mounting block 21, thereby releasing the locking of the mounting block 21 and the heat sealing strip 22. This allows for the disassembly of the mounting block 21 and the heat sealing strip 22, making it convenient for workers to disassemble the heat sealing strip 22 for maintenance and replacement, shortening downtime and improving production efficiency.

[0032] Furthermore, four sets of mounting bolts 3 are symmetrically distributed on the surface of a set of mounting bases 2. The mounting bolts 3 are used to install the mounting plate 31 and the silicone thermal pad 32 on the mounting base 2, and at the same time realize the detachability of the silicone thermal pad 32, so as to facilitate the staff to remove the silicone thermal pad 32 for replacement. The mounting plate 31 is movably connected to the mounting base 2 through the mounting bolts 3, and the mounting plate 31 is used to install the silicone thermal pad 32 on the mounting base 2.

[0033] Furthermore, the silicone thermal pad 32 is movably connected to the mounting plate 31 and the heat sealing strip 22. The silicone thermal pad 32 has good thermal conductivity and elasticity, and can deform under heat sealing pressure, thereby effectively compensating for unevenness caused by various reasons, ensuring uniform pressure in the heat sealing area, sufficient heat transfer, eliminating false sealing and leakage, and greatly improving the sealing strength and consistency of the seal. The silicone thermal pad 32 is an existing product and is not a technical protection point of this application, so it will not be described in detail here.

[0034] Working principle: Pulling the lever 27 moves the insert rod 26 backward, causing the insert rod 26 to disengage from the mounting block 21. This releases the locking of the mounting block 21 and the heat sealing strip 22, allowing the mounting block 21 and the heat sealing strip 22 to slide off the mounting base 2, thus enabling the disassembly of the mounting block 21 and the heat sealing strip 22. This facilitates the disassembly of the heat sealing strip 22 for maintenance and replacement by the staff, shortening downtime and improving production efficiency.

[0035] The silicone thermal pad 32 has good thermal conductivity and elasticity, and can deform under heat sealing pressure, thereby effectively compensating for unevenness caused by various reasons, ensuring uniform pressure in the heat sealing area, sufficient heat transfer, eliminating false sealing and leakage, and greatly improving the sealing strength and consistency of the seal. Moreover, the mounting bolt 3 makes the silicone thermal pad 32 removable, which makes it convenient for staff to disassemble the silicone thermal pad 32 for replacement.
