Description

Technical Field

[0001] The invention relates to the technical field of ice bags, in particular to a device for continuously filling ice bags with thin films that can be filled with one-way water. Background Art

[0002] An existing patent discloses a self-sealing water filling port for ice packs (publication number CN202581995U). The patented technology primarily includes a water filling port body, comprising a water inlet and a water outlet formed by pressing two sheets of plastic film together. The inlet is placed outside the ice pack, while the outlet is placed inside. During use, the plastic film of the water filling port is placed over the water nozzle. Water pressure opens the plastic film at the outlet, allowing water to enter the bag. At this point, the plastic film inside the bag floats and hangs in the water, unable to open. Therefore, water cannot leak out of the outlet. This product has a simple structure, is safe and convenient to use, and is low-cost.

[0003] The problem with the ice bags in the above patents and the prior art is that continuous filling cannot be achieved when water is poured into the ice bags. A single ice bag needs to be held manually and the water inlet of the ice bag is connected to the water outlet of the water filling device until the water filling is completed. This is inefficient and it is impossible to fill multiple ice bags at one time. For this reason, technicians in this field have proposed a continuous filling and one-way water inlet thin film ice bag filling device. Summary of the Invention

The inner surface of the top of the back film of the bag body is provided with a non-return film. The non-return film and the non-edge part of the back film of the bag body are connected by a plurality of hot melt welding points.

[0009] Furthermore, a cutting portion is provided between two adjacent ice bag assemblies, and the cutting portion is a linear structure.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0030] See also Figure 1-3 The present invention provides a technical solution: a continuous filling one-way water inlet film ice bag filling device, including several ice bag components 2 connected together, the continuous filling connecting part 1 and the ice bag component 2 are components made of transparent plastic material, the continuous filling connecting part 1 and the ice bag component 2 are a whole, and are made through a mold hot pressing molding process, the inlets of several ice bag components 2 are commonly connected to the continuous filling connecting part 1, in order to facilitate the subsequent cutting work, a cutting part 3 is provided between two adjacent ice bag components 2, and the cutting part 3 is a linear structure.

[0031] Among them, the continuous filling connection part 1 includes a channel upper seal 11 and a channel lower seal 12 connected to several ice bag assemblies 2. The channel upper seal 11 and the channel lower seal 12 together form a filling channel 13 for water injection. The filling channel 13 has a water inlet end, and the end corresponding to the water inlet end is in a sealed state.

[0032] In addition, the ice bag assembly 2 includes a front film 21 of the bag body and a back film 22 of the bag body. The edges of the front film 21 of the bag body and the back film 22 of the bag body form a bag sealing edge 23 (also made by a mold hot pressing molding process). The front film 21 of the bag body, the back film 22 of the bag body and the bag sealing edge 23 together form a bag structure. The top of the bag structure is provided with a plurality of water inlets 24. Each water inlet 24 is connected to the filling channel 13 (ensuring that the water in the filling channel 13 can be quickly diverted to each bag structure through the water inlet 24). A non-return film 25 is provided on the inner surface of the top of the back film 22 of the bag body (the back film 22 of the bag body and the non-return film 25 have a certain affinity effect. The water pressure of the water coming in from the water inlet 24 will break the affinity effect, causing the back film 22 of the bag body and the non-return film 25 to be partially separated and non-stick. The top of the anti-return film 25 extends to the position of the water inlet 24 and is adapted to the shape of the water inlet 24. The anti-return film 25 is connected to the non-edge part of the bag body back film 22 by a number of hot melt welding points 26 (the hot melt welding points 26 are formed by point pressure of the hot melt gun head. When the bag body back film 22 and the anti-return film 25 are separated by water pressure, the hot melt welding points 26 can play a certain restraining role on the anti-return film 25, so that the separation range is smaller, and water can enter the bag body cavity). The corners of the bag structure are provided with R angles 27 (the setting of the R angle 27 makes the corners of the bag structure rounded, which improves the aesthetics while preventing right angles from causing cutting injuries to users).

[0033] When in use, water is injected into the ice bag assembly 2. When injecting water, the water inlet end of the filling channel 13 is connected to the water injection gun head of the injection device. After the injected water enters the filling channel 13, it flows into the cavity of each bag structure through the water inlet 24. During the inflow process, the water flow will pass between the bag body rear film 22 and the anti-return film 25, breaking the affinity effect between the bag body rear film 22 and the anti-return film 25, so that the bag body rear film 22 and the anti-return film 25 are separated, and under the constraint of several hot melt welding points 26, several longitudinal water injection channels are formed, and the water flows into the cavity of the bag structure. With continuous water injection, more and more water in the cavity causes the bag structure to gradually expand. When the water in the cavity is filled, the water pressure will exert a force on the anti-return film 25 (such as Figure 4 As shown), the force is directed toward the bag body rear film 22, causing the parts that have just been separated to stick together again, thereby achieving an automatic sealing effect of the bag body structure.

There are multiple sets of pressing wheels 99, sealing rubber wheels 910 and pulling wheels 911 (multiple sets of pressing wheels 99 and sealing rubber wheels 910 are rotatably installed inside the protective box 8, and the pulling wheel 911 is driven by a pulling motor installed inside the protective box 8, and the pulling motor is not shown in the figure). Multiple sets of pressing wheels 99, sealing rubber wheels 910 and pulling wheels 911 are distributed on the upper and lower parts of the water injection pipe 93. A waste cutting tool 98 with a cutting edge facing outward is installed on the surface of the water injection pipe 93 and between the sealing rubber wheel 910 and the pipe joint 92.

[0036] When in use, the film ice bag of Example 1 is made into a roll and installed on the unwinding rack 16. The free end of the film ice bag roll is manually passed through two pressing rollers 15, multiple sets of pressing wheels 99, sealing rubber wheels 910 and pulling wheels 911. During the process, the filling channel 13 of the film ice bag is sleeved on the outside of the water injection pipe 93 (such as Figure 7As shown), the pulling motor is started to drive the pulling wheel 911 to rotate, thereby pulling the film ice bag to move. During the movement, the water pump 6 works to pump the water in the water tank 5 to the pipe joint 92 through the water pipe 97. The pipe joint 92 is connected to the water injection pipe 93, so the water will directly enter the water injection pipe 93 and be discharged through the water injection port 94. Since the filling channel 13 is sleeved on the outside of the water injection pipe 93, combined with the working principle of Example 1, continuous filling can be achieved. After filling, excess waste will be automatically cut when passing through the waste cutting tool 98, and will be introduced between the waste discharge wheels 14, and then pulled by the material receiving motor 10. The film ice bag filled with water will be automatically sealed and move with the ice bag conveyor belt 7 to be transferred to the next process.
