Description

Technical Field

[0001] This utility model relates to the technical field of feeding devices, and in particular to a feeding device for self-heating package processing. Background Technology

[0002] Self-heating packs are devices in self-heating food products that use a chemical reaction to release heat and heat. They are typically made of a water-permeable textile bag containing a powdery material that reacts chemically with water or oxygen to release heat. The main components of the powdery material inside the self-heating pack include quicklime, iron powder, activated carbon, and diatomaceous earth. Quicklime reacts with water to produce calcium hydroxide and releases a large amount of heat, heating the water quickly to form high-temperature steam, thus achieving the basic function of heating food. Iron powder oxidizes slowly upon contact with oxygen, continuously releasing heat, which helps extend the self-heating time of the pack, keeping the heated food at a high temperature for a longer period. Activated carbon and diatomaceous earth, as adsorbents, adsorb and purify water vapor and other impurities, helping to extend the shelf life of the self-heating pack.

[0003] When mass-producing self-heating packs, the various raw materials that make up the powder material must first be added according to a specific formula ratio to ensure optimal reaction performance. Therefore, the industry typically uses a vacuum feeder to extract the raw materials to a weighing device, and then quantitatively feeds them into a dispensing and sealing device. However, during the extraction and weighing process, some materials may be exposed to air for an extended period, leading to oxidation and exothermic reactions, which negatively impacts the quality of the finished self-heating pack.

[0004] Based on the above existing technologies, it can be seen that the existing self-heating pack production process is prone to premature oxidation and heat release, which in turn affects the quality of the finished self-heating pack. Utility Model Content

[0005] In view of this, the present invention aims to propose a self-heating packaging material feeding device to achieve uniform feeding at a constant ratio and speed, avoid premature oxidation and heat release that may occur during the vacuum feeding and extraction process, thereby improving product quality.

[0006] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0007] A self-heating pack processing and feeding device includes a feeding component, which is fixedly installed on a horizontal ground;

[0008] A roller assembly is rotatably disposed at one end of the feeding assembly near the ground and is connected to the feed end of the feeding assembly;

[0009] A drive assembly is fixedly mounted on a horizontal surface and connected to the feeding assembly and the roller assembly. It is used to drive the feeding action of the feeding assembly and the rotation action of the roller assembly.

[0010] Furthermore, the feeding assembly includes a bracket, which is fixedly installed on a horizontal ground;

[0011] A conveyor belt is mounted on the support and connected to the drive assembly;

[0012] The feed hopper is mounted on the support and is connected to the end of the conveyor belt near the ground.

[0013] Furthermore, baffles are symmetrically arranged on both sides of the conveyor belt, and the baffles are fixed on the support.

[0014] Furthermore, a receiving hopper is provided at the end of the conveyor belt away from the ground, and the receiving hopper is detachably mounted on the support.

[0015] Furthermore, pressure sensors are symmetrically arranged on the side wall of the receiving hopper.

[0016] Furthermore, the roller assembly includes a cylinder that is rotatably disposed within the feed hopper in a horizontal direction;

[0017] A feed pipe is located on the outside of the feed hopper and communicates with the inside of the cylinder.

[0018] The cylinder has multiple through holes of the same diameter evenly distributed on its side wall. The cylinder's rotating shaft extends vertically to the outside of the feed hopper and is connected to the drive assembly via belt drive.

[0019] Furthermore, the feed pipe is a curved pipe with an open top.

[0020] Furthermore, the drive assembly includes a control box, which is vertically mounted on the horizontal ground and located on the side of the conveyor belt closest to the ground.

[0021] A drive motor is located on the top of the control box and is electrically connected to the control box. The power output shaft is connected to the conveyor belt and the cylinder.

[0022] Compared with the prior art, this utility model has the following advantages:

[0023] This invention discloses a self-heating pack processing and feeding device. By incorporating a roller assembly at the feeding end of the feeding component, both the feeding end and the roller assembly can be used to hold two different self-heating pack powders. Driven by a drive assembly, the roller assembly rotates, adding one type of self-heating pack powder at a constant speed and quantity to the feeding end of the feeding component through rolling. The feeding component then lifts the other type of self-heating pack powder, along with the powder flowing out from the roller assembly, to the top of the feeding component at a certain speed, achieving uniform and proportional feeding. Since this process eliminates the need for vacuum feeding and weighing in traditional processes, it shortens the time the self-heating pack powder is exposed to air, mitigating premature oxidation and heat release, and ultimately improving the quality of the finished self-heating pack.

The utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0035] The following will refer to the appendix. Figure 1 To be continued Figure 4 The present invention will be described in detail with reference to the embodiments.

[0036] This embodiment relates to a self-heating pack processing and feeding device. By introducing a roller mixing structure, various powders used in the production of self-heating packs are uniformly mixed to achieve uniform and homogeneous feeding, thereby eliminating the need for pre-weighing. During the feeding process, the material is mixed and can be taken out as needed, solving the problem of premature oxidation and heat release caused by pre-weighing of materials and the inability to package and consume them in the prior art. This is beneficial to improving product quality and has the advantages of simple and reliable structure, easy operation and maintenance.

[0037] In terms of overall structure, refer to Figure 1 This embodiment of a self-heating package processing feeding device includes a feeding assembly 1, a roller assembly 2, and a drive assembly 3. The feeding assembly 1 is fixedly mounted on a horizontal surface. The roller assembly 2 is rotatably mounted on the feeding assembly 1 near the ground and communicates with the feed end of the feeding assembly 1. The drive assembly 3 is fixedly mounted on the horizontal surface and located to one side of the feeding assembly 1. The drive assembly 3 is connected to the feeding assembly 1 and the roller assembly 2, and is used to drive the movement of the feeding assembly 1 and the rotation of the roller assembly 2.

[0038] As described above, by setting a roller assembly 2 at the feeding end of the feeding assembly 1, the feeding end of the feeding assembly 1 and the roller assembly 2 can be used to hold two different self-heating pack powders respectively. The roller assembly 2 can rotate under the driving action of the drive assembly 3, and add one type of self-heating pack powder to the feeding end of the feeding assembly 1 at a uniform speed through rolling. The feeding assembly 1 can then feed and lift the other type of self-heating pack powder and the self-heating pack powder flowing out of the roller assembly 2 to the top of the feeding assembly 1 at a certain speed, realizing the function of uniform speed, proportion, and homogeneous feeding. Since the above process eliminates the steps of vacuum feeding and weighing in the original process, it shortens the time that the self-heating pack powder is exposed to air, and to a certain extent alleviates the phenomenon of premature oxidation and heat release of the self-heating pack powder, thus achieving the invention objective of improving the quality of the finished self-heating pack.

[0039] Reference Figure 1 and Figure 2The feeding assembly 1 includes a support 101, a conveyor belt 102, and a feeding hopper 103. The support 101 is vertically mounted on a horizontal surface, and the conveyor belt 102 is inclinedly mounted on the support 101. The conveyor belt 102 has a feeding plate that rotates with the belt surface, transporting the self-heating pack powder from the bottom of the conveyor belt 102 to the top. The feeding hopper 103 is installed at the end of the conveyor belt 102 near the ground. The top of the feeding hopper 103 has an opening for adding a self-heating pack powder. The two self-heating pack powder materials are mixed in the feeding hopper 103 near the bottom of the conveyor belt 102, and then transported by the conveyor belt 102 to the top of the feeding assembly 1. The feeding hopper 103 can be connected to equipment capable of quantitatively adding powder materials, such as a feed bell or disc feeder, allowing adjustment of the feeding speed to change the proportions of the two self-heating pack materials. Baffles 104 are symmetrically arranged at both ends of the conveyor belt 102. These baffles effectively prevent material from spilling from both sides of the conveyor belt 102 to the outside of the equipment. A receiving hopper 105 is located at the end of the conveyor belt 102 furthest from the ground. The receiving hopper 105 is located below the discharge port of the conveyor belt 102 and is detachably mounted on the support 101 via bolts. Pressure sensors are symmetrically arranged on the side walls of the receiving hopper 105 and are electrically connected to the drive assembly 3. After detecting a pressure signal, the pressure sensor transmits it to the drive assembly 3, providing a reference for speed adjustment and preventing excessive material spillage from the receiving hopper 105.

[0040] Reference Figure 1 and Figure 3 The roller assembly 2 includes a cylinder 201 and a feed pipe 202. The cylinder 201 is rotatably connected inside the feed hopper 103. Rotating shafts are located at both ends of the cylinder 201, passing through the two side walls of the feed hopper 103 to form a rotatable connection structure. A pulley is installed at one end of each rotating shaft of the cylinder 201, and the pulley is connected to the drive assembly 3 via a belt for synchronous transmission. The cylinder 201 is a cylindrical tube made of metal with a discharge hole. The size of the discharge hole in the cylinder 201 is determined by the required feeding speed, which is determined by the self-heating powder formulation ratio. By adjusting the diameter of the discharge hole, the material inside the cylinder 201 flows into the feed hopper 103 at a certain speed. The rotation of the cylinder 201 reduces the impact of discharge hole blockage on the feeding speed. The feed pipe 202 is a right-angle bend with an open top. The feed pipe 202 is connected to the inside of the cylinder 201. The amount of material in the cylinder 201 can be kept balanced by continuously adding material into the open top of the feed pipe 202, so as to ensure that the feeding speed does not fluctuate greatly.

[0041] Reference Figure 1 and Figure 4The drive assembly 3 includes a control box 301 and a drive motor 302. The control box 301 is vertically fixed on a horizontal surface, located on the side of the conveyor belt 102 closest to the ground. The drive motor 302 is mounted on top of the control box 301 and electrically connected to it. The control box 301 is electrically connected to a pressure sensor, and its outer surface is equipped with function buttons for start, stop, and emergency stop. The control box 301 controls the operation of the drive motor 302. The power output shaft of the drive motor 302 is connected to the power shaft of the conveyor belt 102 via a coupling, and is also connected to a pulley on the rotating shaft of the cylinder 201 via belt drive, thereby realizing power transmission.
