Description

Technical Field

[0001] The invention relates to the technical field of refrigerated transport equipment, and in particular to a filling device for continuous ice bags. Background Art

[0002] In today's refrigerated logistics field, keeping goods at a suitable temperature during transportation is an important factor in ensuring the quality and safety of goods. In traditional refrigeration equipment, ice bags, as a common temperature control tool, play a vital role. Refrigerated ice bags can refrigerate and preserve perishable products such as vegetables, fruits, foods, biological preparations and all products that require refrigerated transportation to prevent them from spoiling. However, there are some problems with the use of existing ice bags and a lack of professional equipment.

[0003] First, although water-free ice packs are easy to use, they contain water, which makes them bulky and heavy, thus increasing procurement and transportation costs. This is particularly prominent in logistics, because the size and weight of the ice packs directly affect the loading capacity and transportation costs of the goods.

[0004] Secondly, water-filled ice bags need to be filled with water manually one by one, which is not only inefficient, but also increases labor costs and operational complexity. This method not only wastes time, but also increases the labor intensity of staff, which is not conducive to improving logistics efficiency and reducing operating costs.

[0005] In addition, although existing water-absorbing ice bags can absorb water, they cannot have built-in refrigerants, which makes it difficult for ice bags to maintain a stable low-temperature environment during long-term transportation. As a result, the temperature of the goods may fluctuate, affecting the quality and safety of the goods, especially for special goods such as perishable items or medicines, the risk is more obvious.

[0006] In summary, in response to the problems existing in these existing ice bags, there is an urgent need for an innovative filling device that can overcome the above challenges, improve the refrigeration effect, reduce transportation costs and labor costs, and thus better meet the needs of the refrigerated logistics field.

[0049] It should be emphasized that the term “include / comprises” when used herein refers to the presence of features, elements, steps or components, but does not exclude the presence or addition of one or more other features, elements, steps or components.

[0050] It should also be noted that, unless otherwise specified, the term “connection” herein may refer not only to a direct connection but also to an indirect connection with an intermediate.

[0051] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the accompanying drawings, the same reference numerals represent the same or similar components, or the same or similar steps.

[0052] The present invention provides a filling device for a continuous ice bag, which is suitable for a continuous ice bag. The continuous ice bag is different from the ice bag in the prior art, such as Figure 2 As shown, the continuous ice pack includes a plurality of single ice packs 21 arranged side by side, and each of the single ice packs 21 is connected in sequence along a set direction. The set direction mentioned here may refer to the length direction of the continuous ice pack. This arrangement allows the cold storage ice packs to be stored in an orderly manner for automated water filling operations or convenient logistics transportation. A water flow channel 22 is provided on one side of the continuous ice pack, and the water flow channel 22 is connected to the water inlet 23 of each of the single ice packs 21; see Figure 1 The water flow channel 22 is arranged on the top of the continuous ice pack, and is a common channel for all the individual ice packs 21, which is convenient for users to inject cold storage liquid and provides water filling space for the automatic water filling operation of the filling device. This continuous ice pack and filling device with innovative design will bring many advantages, including improving efficiency, reducing costs, increasing flexibility and applicability, etc. This innovation is expected to have a positive impact in the field of refrigerated transportation.

[0053] Optionally, the material of the continuous ice bag can be PVC (polyvinyl chloride), PE (polyethylene) or a multi-layer composite material, etc. It is understandable that the above-mentioned water injection operation or water filling refers to filling the ice bag with a cold medium or a cold storage solvent, and the liquid used can be pure water, tap water or other liquids, and of course it can also be a solution mixture with a solute.

[0054] In some embodiments, Figure 1 As shown, the filling device includes an ice bag storage component, a water injection component and a cutting component. The ice bag storage component is used to place and transport continuous ice bags to achieve automatic and orderly transportation of continuous ice bags; the water injection component is used to achieve quantitative transportation of water flow; and the cutting component is used to cut the water flow channel 22 to achieve the continuity of the water injection operation.

[0055] Among them, Figure 3-Figure 5 As shown, the ice bag storage assembly is used to store rolled or stacked continuous ice bags, and allows the continuous ice bags to be released smoothly one by one. Optionally, if the continuous ice bag is a rolled ice bag, the ice bag storage assembly includes a reel 111 for winding and placing the rolled ice bag. Optionally, if the continuous ice bag is a stacked ice bag, the ice bag storage assembly includes a storage box for placing the stacked ice bags. It is understandable that the continuous ice bag can be stored in a rolled or stacked manner, or in other storage manners, and different storage methods correspond to different storage structures.

[0056] The water injection assembly includes a water injection pipe 121 and a sealing mechanism 15. The water injection pipe 121 has a water injection section, and the water injection section is provided with at least one water outlet 122. The diameter and shape of the water injection pipe 121 are designed to be able to be inserted into the water flow channel 22 of the continuous ice bag. The sealing mechanism 15 is provided on the outer peripheral side of both ends of the water injection section, and is used to press the water flow channel 22 corresponding to the sealing mechanism 15 on the outer peripheral wall of the water injection pipe, so that the water flowing out of the water outlet 122 of the water injection section can only enter the corresponding single ice bag 21 through the water injection port, thereby realizing the function of filling water. The length of the water injection section is the spacing distance of the sealing mechanism 15. Multiple single ice bags 21 can be placed in this distance, that is, the device can simultaneously perform water injection operations on multiple single ice bags 21, and can be performed continuously to maintain the continuity of the production process and the water injection efficiency. Optionally, the outer diameter of the water injection pipe may be equal to or slightly smaller than the inner diameter of the water flow channel 22 after it is expanded, so as to seal and prevent the water from flowing to other parts, such as overflowing or passing through the water flow channel that does not enter the water injection section.

[0057] The cutting assembly includes a cutter 131 and a traction mechanism. The cutter 131 is arranged on one side of the water injection pipe 121. Along the transmission direction of the continuous ice bag, the cutter 131 is located behind the water injection section, and the traction mechanism is located behind the cutter 131, so that under the pulling action of the traction mechanism on the continuous ice bag, the cutter 131 cuts the water flow channel 22 of the single ice bag 21 after water injection, and the single ice bag 21 can be separated from the water injection pipe 121. The traction structure is used to provide power for the transmission of the continuous ice bag so that it can be pulled, and the water flow channel is cut off during the pulling process, and is used to release the water injection pipe 121 from the water flow channel of the ice bag, so as to continuously carry out the water injection operation and remove and collect the water-injected ice bag.

[0058] In the above embodiment, the operation process of the filling device has a high level of automation. The continuous ice bag is released from the storage component, and its front end can be manually inserted into the water injection pipe. Then the continuous ice bag passes through the water injection section of the water injection pipe, and the water outlet of the water injection section introduces water flow into the water injection port of each single ice bag. At the same time, the sealing mechanism ensures that the water flow can only enter the corresponding single ice bag. Then, the cutting component separates the water-filled single ice bag from the water injection pipe through the cutter and the traction mechanism, and the filling process is automatically completed.

[0059] The filling device in the embodiment of the present invention is combined with the innovatively designed continuous ice bag to realize the continuous water filling of the ice bag, improve production efficiency, and reduce the transportation cost and water filling cost of the ice bag; because the continuous ice bag may be relatively light and can be filled with water on site when needed, since there is no need to carry a large amount of water during transportation, this greatly reduces the transportation cost of the ice bag. If combined with the placement of a refrigerant in the ice bag in advance, the cold storage capacity of the ice bag can be greatly improved, which can enable the ice bag to provide a longer refrigeration effect when used, and is particularly suitable for scenarios that need to maintain low temperatures for a long time. The number of single ice bags used can be arbitrarily combined, the use scenarios are flexible and changeable, and the applicability is increased, thereby meeting the refrigeration needs of different scales and needs.

[0060] In some embodiments, the sealing mechanism 15 is any one of a roller seal, a pneumatic seal and a clamp seal. The roller seal mechanism can use a pair of rotatable rollers to press the water flow channel of the continuous ice bag from both sides of the end of the water injection section of the water injection pipe. The linear speed of the pressing part of the roller is equal to the running speed of the continuous ice bag, so that it can still achieve the fixed-point pressing function during the movement. The pneumatic sealing mechanism can be designed as a negative pressure structure of the water injection pipe or an external positive pressure structure. For example, the water injection pipe is designed with a negative pressure structure at the end of the water injection section (i.e., in the water flow channel), and the water flow channel of the continuous ice bag can be adsorbed through the annularly evenly distributed negative pressure holes; the external positive pressure structure is similar, and air pressure can be used in the water flow channel to press the film of the water flow channel onto the water injection pipe, thereby achieving a sealing function. The clamp-type sealing mechanism can use a rubber sealing ring or an airbag sealing ring to clamp the film of the water flow channel at the end of the water injection section of the water injection pipe. The sealing ring is designed to prevent water from passing through, but allow the water flow channel to move. The above is only an example. The choice of sealing method depends on specific needs, including the strength and adaptability of the seal and the design requirements of the equipment.

[0061] In some embodiments, the sealing mechanism 15 includes at least a first roller group 151 and a second roller group 152 respectively disposed at both ends of the water injection section of the water injection pipe 121. Specifically, the first roller group 151 and the second roller group 152 each include two symmetrically disposed rollers, and an annular groove is disposed in the middle of the roller, so that the water injection pipe 121 can be inserted into the annular groove, and the water flow channel 22 of the continuous ice pack can be pressed against the outer peripheral wall of the water injection pipe; the annular grooves of the two rollers can together form a closed circle, which is the same as the cross-section of the water injection pipe 121. The first roller group 151 and the second roller group 152 combined with the water injection pipe 121 can press the water flow channel 22 of the continuous ice pack to achieve sealing, prevent water leakage, and also achieve precision in water injection operations.

[0062] Optionally, the first roller set 151 and the second roller set 152 are powered wheels or unpowered wheels. The powered wheels can better compress and convey continuous ice packs through friction.

[0063] In some embodiments, the water injection pipe 121 is used to extend into the water flow channel 22, and is used to inject water into the water flow channels 22 of several ice bag sections located between the first roller group 151 and the second roller group 152, so that water flows into each single ice bag 21 through the water injection port. By sharing the water flow channel 22 and the annular groove design, multiple single ice bags 21 can be injected with water at the same time, thereby improving efficiency.

[0064] In some embodiments, the traction mechanism includes a third roller group 161, which includes two symmetrically arranged rollers, and an annular groove is arranged in the middle of the rollers, so that the water injection pipe 121 can be inserted into the annular groove; the third roller group 161 can compress the cut water flow channel 22 and convey it forward by friction, providing power to the water flow channel passing through the cutter. In addition to using rollers for conveying, the traction mechanism can also use other conveying methods, such as clamps, transmission belts, etc. In other embodiments, the traction mechanism includes a group of symmetrically arranged transmission belt mechanisms, and the two transmission belt mechanisms are respectively arranged on the upper and lower sides of the continuous ice bag, and are configured to clamp the water flow channel 22, so that it can clamp and convey the cut continuous ice bag. The transmission belt mechanism and the third roller group 161 can use friction and compression to realize the conveyance of the ice bag after water injection and provide traction for the forward cutting of the water flow channel. In addition, the traction mechanism may also adopt a structure similar to a clamp, and the clamp is installed on a rotatable wheel or a closed conveyor belt. The rotation of the wheel or the conveyor belt drives the cut water flow channel to move forward, thereby providing traction.

[0065] In the above embodiment, the cutter 131 is disposed at a position corresponding to between the second roller group 152 and the third roller group 161, and the cutter 131 is used to cut the water flow channel 22 of the water-filled single ice bag 21, so that the water-filled single ice bag 21 can be separated from the water filling pipe 121. The cutting assembly can automatically cut the water-filled ice bag without manual operation, thereby improving production efficiency.

[0066] In the above embodiment, the ice bag storage component realizes the sequential delivery of ice bags through the coordinated action of the unwinding shaft 111 and a series of roller groups. The design of the continuous ice bag facilitates the orderly storage and automatic conveying of the ice bags. The water injection component uses the water injection pipe 121 and the water outlet 122 to accurately give each single ice bag 21 the amount of water injection, ensuring that each single ice bag 21 is fully filled with water. Finally, the cutter 131 of the cutting component ensures that the ice bag can be independently separated from the water injection pipe 121 after water injection, completing the entire filling process.

[0067] In the above embodiment, the pipe section of the water injection pipe 121 corresponding to the first roller group 151 and the second roller group 152 is used for water injection operation, and the single ice bag 21 of the continuous ice bag in the pipe section is subjected to water injection operation. During the water injection process, the first roller group 151 and the second roller group 152 respectively press the two ends of the water flow channel 22 of the water injection section, and the third roller group 161 is used to tighten the continuous ice bag so that the water flow channel 22 of the ice bag after water injection can be cut open, thereby realizing the process of disengaging the water injection pipe 121 from the water flow channel 22, and facilitating automatic and continuous water injection.

[0068] In some embodiments, the roller includes a soft layer arranged in an annular shape on its outer circumference for compacting and sealing the continuous ice pack. The annular arrangement of the soft layer can provide better pressure distribution, thereby compacting and sealing the water flow channel 22 of the ice pack more effectively. The main function of the annular arrangement of the soft layer of the roller is to prevent water from leaking into the non-water injection section and to prevent changes in the water injection amount. This design can effectively control the water flow and maintain a stable water injection amount, which helps to ensure the normal operation of the system and the stability of the production process.

[0069] In some embodiments, Figure 1 As shown, the filling device includes a body, the unwinding shaft 111 is arranged on one side of the body, and the ice bag storage assembly also includes a guide shaft 112 arranged between the unwinding shaft 111 and the first roller group 151, and the guide shaft 112 is provided with at least one, and the guide shaft 112 is fixedly set or slidably adjusted, and its sliding direction includes but is not limited to the conveying direction along the continuous ice bags; by setting the guide shaft 112, the stable guidance of the ice bags between the unwinding shaft 111 and the first roller group 151 can be ensured, thereby ensuring the accuracy and stability of the ice bag transmission and processing during the production process.

[0070] In the above embodiment, the slidable adjustable setting mode can adopt a variety of structural designs, such as a slider design, a screw adjustment design, and a pull rod adjustment design. Taking the slider design as an example, a slidable water injection pipe 121 bracket or an adjustment device can be designed on one side of the body of the filling device, and the position of the water injection pipe 121 can be adjusted through the structure of the slider and the guide rail. In this way, the position of the water injection pipe 121 can be adjusted as needed to ensure that each ice pack unit can be fully filled with water.

[0071] In the above embodiment, two or more guide shafts 112 may also be provided. When there are multiple guide shafts 112 provided in the system, if one guide shaft 112 fails or has problems, other guide shafts 112 may take over the work to ensure the continuity and stability of the system. This redundant design can improve the fault tolerance of the system and reduce production interruptions caused by a single failure. The setting of multiple guide shafts 112 can achieve more complex and precise motion control. By comprehensively utilizing the advantages of different guide shaft 112 settings, the motion path and efficiency of the system can be optimized to achieve a higher level of control accuracy. For example, different guide shaft 112 settings can also be used to obtain a variety of feedback information (such as setting a tension sensor) to help the system more accurately perceive and adapt to complex working scenarios.

[0072] In some embodiments, Figure 1 and Figure 3As shown, the filling device also includes a support plate 171, which is arranged along the extension direction of the water injection pipe 121 and is located below the first roller group 151, the second roller group 152 and the third roller group 161, and is used to support the single ice bag 21 after water injection. The setting of the support plate 171 can provide a support platform, which can ensure that the ice bag maintains a stable position during the water injection and filling process, avoids deformation or displacement, and is conducive to subsequent transfer. Through the design of the support plate 171, the ice bag will be effectively supported after filling, making operation and management simpler, and is also conducive to the operation of the automated production line and improving production efficiency. With the support of the support plate 171, the ice bag can be protected after filling to avoid deformation or damage, thereby improving the overall quality and consistency of the product.

[0073] In some embodiments, the sealing mechanism 15 includes more than two roller groups, wherein the two roller groups are respectively arranged at the two ends of the water injection section of the water injection pipe 121, and the linear speeds of the pressing parts of the two rollers of the same roller group are configured to be equal, so as to smoothly seal and convey continuous ice bags. Furthermore, when the sealing mechanism 15 includes more than three roller groups, the water injection section of the water injection pipe 121 is divided into a plurality of water injection units, and the water injection units are all configured with the water outlet 122, which is used to inject water into at least one single ice bag 21, and the boundary position of each water injection unit is configured with the roller group, which is suitable for injecting water into multiple single ice bags 21 in sections to improve the water injection efficiency.

[0074] In some embodiments, each of the roller groups is driven by a single power source through a synchronous transmission mechanism, or is synchronously driven by different power sources, so that the conveying speed of the continuous ice pack at each position on the water injection pipe 121 remains consistent. The roller group described here may include only the roller group of the sealing mechanism 15, or may include the roller group of the sealing mechanism 15 and the roller group of the traction mechanism. If it is set as a single power source, its driving method is relatively simple, and synchronization can be achieved only by relying on a mechanical transmission structure. The synchronous transmission mechanism that can be used includes but is not limited to gear mechanisms, gear racks, transmission belts (synchronous belts), transmission chains (synchronous chains) and other mechanisms. If it is set as multiple power sources, its transmission method is relatively simple. For example, if a motor or a reduction motor is used to directly drive the roller group, the synchronous control of its driving method will be relatively complicated, and it is necessary to ensure the synchronous drive of multiple power sources.

[0075] As a feasible method, Figure 3 and Figure 6-Figure 8 As shown, the first roller group 151 and the second roller group 152 are powered wheel groups; the filling device further includes a power assembly, which includes a power source 141, a first transmission wheel group 142, a second transmission wheel group 143, etc. The power assembly includes multiple transmission wheel groups, which can realize simultaneous transmission of multiple roller groups so that continuous ice packs can be smoothly transmitted.

[0076] Among them, Figure 6 As shown, the first transmission wheel group 142 includes: a first transmission shaft 142-1a and a first gear 142-1c and a first transmission wheel 142-1b installed on the first transmission shaft 142-1a; a second transmission shaft 142-2a and a second gear 142-2c and a second transmission wheel 142-2b installed on the second transmission shaft 142-2a. The first transmission shaft 142-1a is connected to the output shaft of the power source 141, and the first gear 142-1c and the second gear 142-2c are meshed and connected, and the transmission ratio is 1, so as to drive the first transmission shaft 142-1a and the second transmission shaft 142-2a to rotate synchronously. One roller in the first roller group 151 is installed on the first transmission shaft 142-1a, and the other roller is installed on the second transmission shaft 142-2a. It can be understood that the first gear 142-1c and the second gear 142-2c have the same number of teeth and diameter. This design ensures that when the first gear 142-1c and the second gear 142-2c are engaged and connected, they will rotate at the same speed to ensure sealing and continuous delivery of ice packs.

[0077] Further, the second transmission wheel group 143 includes: a third transmission shaft 143-1a and a third transmission wheel 143-1b and a fourth transmission wheel 143-1c installed on the third transmission shaft 143-1a; a fourth transmission shaft 143-2a and a fifth transmission wheel 143-2b and a sixth transmission wheel 143-2c installed on the fourth transmission shaft 143-2a. The third transmission wheel 143-1b is connected to the first transmission wheel 142-1b through a flexible transmission member, and the fifth transmission wheel 143-2b is connected to the second transmission wheel 142-2b through a flexible transmission member, so that the second transmission wheel group 143 can be driven by the first transmission wheel group 142. One roller in the second roller group 152 is installed on the third transmission shaft 143-1a, and the other roller is installed on the fourth transmission shaft 143-2a. Such a design can realize the transmission relationship between the first transmission wheel group 142 and the second transmission wheel group 143, and through the connection of the flexible transmission member, a certain degree of elastic transmission can be realized, thereby reducing the transmission of shock and vibration, and improving the reliability and stability of the system. The flexible transmission member can be a component that can have a certain elasticity and deformation ability during the transmission process to realize the function of transmitting power or torque. The flexible transmission member can be made of different materials and structural forms, such as chain drive or belt drive. In order to improve synchronization, a synchronous belt can also be used, and each transmission wheel is selected as a synchronous pulley.

[0078] Further, the traction mechanism includes a third transmission wheel group 144, and the third transmission wheel group 144 includes: a fifth transmission shaft 144-1a and a seventh transmission wheel 144-1b installed on the fifth transmission shaft 144-1a; a sixth transmission shaft 144-2a and an eighth transmission wheel 144-2b installed on the sixth transmission shaft 144-2a. The seventh transmission wheel 144-1b is connected to the fourth transmission wheel 143-1c through a flexible transmission member, and the eighth transmission wheel 144-2b is connected to the sixth transmission wheel 143-2c through a flexible transmission member, so that the third transmission wheel group 144 can be driven by the second transmission wheel group 143. One roller in the third roller group 161 is installed on the fifth transmission shaft 144-1a, and the other roller is installed on the sixth transmission shaft 144-2a. Such a design can realize the transmission relationship between the second transmission wheel group 143 and the third transmission wheel group 144, and realize a certain degree of elastic transmission through the connection of flexible transmission parts, thereby reducing the transmission of shock and vibration and improving the reliability and stability of the system.

[0079] In some embodiments, Figure 3 and Fig. 9 As shown, the water injection assembly includes a water diversion pipe 124 and a solenoid valve 127, a pressure regulating valve 126 and a flow meter 125 arranged on the water diversion pipe 124, which are respectively used to control the on and off of the water injection assembly, adjust the water flow pressure and monitor the water inlet speed. The end of the water diversion pipe 124 is connected to the water injection pipe 121. Specifically, the water diversion pipe 124 can be arranged on the side of the body away from the water injection pipe 121. With the side of the water injection pipe 121 of the body or the side where the continuous ice pack is placed as the front side, the water diversion pipe 124 can be arranged on the rear side or the left and right sides of the body to facilitate the entry of water flow. The solenoid valve 127 can control the on and off of the water flow through an electrical signal to achieve precise control of the water injection process. The pressure regulating valve 126 is used to maintain a stable pressure of the water flow to ensure that the water flow pressure is within a set range. The flow meter 125 is used to monitor the entry speed of the water flow so as to timely understand the water usage and flow rate for real-time monitoring and regulation.

[0080] Since the end of the water injection pipe 121 (the end facing the unwinding shaft 111) needs to penetrate into the water flow channel 22 of the continuous ice pack, the end of the water injection pipe 121 or the entire water injection pipe 121 needs to be suspended, and the water guide pipe 124 is connected to the water injection pipe 121. The continuous ice pack needs to be separated from the water injection pipe 121 after water injection, and the cutting assembly is used to cut the water flow channel 22. Furthermore, the end of the water injection pipe 121 can be chamfered and have a guide structure to facilitate entry into the water flow channel 22 of the continuous ice pack.

[0081] Furthermore, the end of the water injection pipe 121 is closed, such as Fig. 9As shown, the direction of the water outlet 122 is set to be toward the water injection port of the single ice bag 21. This design can ensure that the water flow can directly enter the water injection port of the single ice bag 21, so as to quickly inject the water flow into each single ice bag 21, thereby effectively realizing the water injection operation of the ice bag.

[0082] In some embodiments, Figure 3 and Fig. 9 As shown, the water injection assembly further includes a flow regulating valve 123 disposed between the water diversion pipe 124 and the water injection pipe 121, which is used to adjust the water flow rate of the water injection pipe 121 by manual, electric or automatic control. The addition of the flow regulating valve 123 can make the water injection flow rate more flexible and controllable, and can be adjusted manually or automatically according to the needs of specific scenarios to adapt to different working conditions and usage requirements.

[0083] In some embodiments, the filling device can use external water supply or a self-contained water tank to replenish water, or both of these water supply methods. Fig. 9 As shown, the water injection assembly also includes a water inlet interface 128 arranged at the front end of the water diversion pipe 124, and the water inlet interface 128 is used to access a water flow with water pressure, such as tap water. The water diversion structure of the filling device in this manner is relatively simple, the overall equipment is small in size, the cost is low, and it is convenient and easy to use. Taking the method of bringing a water tank as an example, the water injection assembly also includes a water storage tank and a water pump, which are used to provide water to the water diversion pipe 124. The water pump draws water from the water storage tank and transports it to the water injection assembly through the water diversion pipe 124. This design is used in situations where independent water supply is required, such as in places where there is no direct water source or where continuous large-scale water injection is required. The filling device of this embodiment can make the water injection method more flexible and can adapt to different working environments and usage requirements. They can be selected and used in combination according to specific circumstances to ensure the stability and efficiency of the system.

[0084] In some embodiments, the water inlet speed, water flow pressure and continuous ice bag conveying speed driven by the ice bag storage assembly of the filling device are configured to fill each individual ice bag 21 with a set pressure while the continuous ice bag is conveying continuously. In this embodiment, the water inlet speed is set to be able to inject water into the interior of the ice bag at an appropriate speed while the continuous ice bag is conveying continuously. This ensures the continuity and efficiency of the filling process. The water flow pressure is adjusted to a certain set value to ensure that each individual ice bag 21 can be fully filled while the ice bag is conveying continuously. The control of the water flow pressure can ensure the uniformity and accuracy of the water injection. This design ensures that the filling device can fill each individual ice bag 21 with an appropriate pressure and speed while the continuous ice bag is conveying continuously, thereby achieving efficient and accurate water injection operation.

[0085] In some embodiments, the filling device further includes a display panel, at least for real-time flow. The display panel can be arranged on the outer shell of the body, and the display panel can display the current real-time flow data of the filling device, so that the operator can monitor the water flow during the filling process at any time, so as to improve the accuracy and stability of the filling operation. In addition to the real-time flow data, the display panel can also display other relevant information, such as the working status of the filling device, the water injection speed, the water flow pressure, etc. This information can help the operator to adjust the filling parameters in time to ensure the smooth progress of the filling process.

[0086] In some embodiments, when there is one cutter 131 of the cutting assembly, the cutter 131 is arranged in a direction perpendicular to the water injection pipe 121, and the cutter 131 can be located on one side of the water injection pipe 121 and cross the horizontal plane where the central axis of the water injection pipe 121 is located, so as to ensure that the ice bag is not interfered by the pipe when cutting. Figure 5 As shown, when two cutting knives 131 of the cutting assembly are provided, the two cutting knives 131 are symmetrically arranged about the horizontal plane where the central axis of the water injection pipe 121 is located, and their tips are against the outer wall of the water injection pipe 121, ensuring that the pipe structure will not be damaged while cutting the water injection pipe 121 during the cutting process. In this embodiment, the cutting assembly can effectively cut the water flow channel 22 of the continuous ice pack to facilitate the continuous automatic water injection operation of the continuous ice pack.
