Description

Technical Field

[0001] The utility model relates to the technical field of packaging production sealing equipment, and particularly relates to a powder packaging sealing heat-sealing and pressing machine. Background Technique

[0002] The powder packaging heat-sealing and pressing technology is one of the core processes in the packaging link of the powder industry, and is mainly applied to the sealing and packaging of powdery and granular materials in the fields of food, chemical industry, pharmacy, etc. Its core function is to form a uniform and reliable sealing layer on the contact surface of packaging materials through precise temperature and pressure control, effectively isolating the intrusion of external water vapor, oxygen and microorganisms, preventing the powder from getting damp and caking, oxidizing and deteriorating or cross-contaminating, and at the same time avoiding the loss caused by the powder escaping during transportation. This technology is directly related to the stability of the product shelf life, quality compliance and supply chain efficiency, and is especially suitable for the automated production and long-distance transportation of high-value-added powders (such as milk powder, pharmaceutical raw materials, nano materials), and is the key technical support for realizing refined packaging management and efficient utilization of resources.

[0003] The prior art has the following deficiencies: In the "electric hot-pressing and sealing device" with the publication number of CN205060154U in the prior art, "it includes: a workbench frame (1), a heat-sealing device (2) is installed above the workbench frame, a temperature regulator (9) is installed on the middle support plate inside the workbench frame, an electric constant-speed working device (12) is installed below the temperature regulator, the lower side of the electric constant-speed working device is connected to a motor (13) through a connecting shaft, and the side of the motor is connected to the inner side plate of the workbench frame through bolts, and the temperature regulator internally has an electronic constant-temperature controller".

[0004] The above structure achieves the effect of determining the sealing temperature according to the material of the product to be packaged by setting a heat-sealing device, a temperature regulator and an electric constant-speed working device. This structure performs sealing through traditional double-end hot pressing, and after hot-pressing and sealing, it is necessary to manually take away the packaging material. If the speed is slightly slower, the packaging material will melt and stick, resulting in poor continuity of the heat-sealing step. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a powder packaging sealing heat-sealing and pressing machine, which solves the problem of poor continuity caused by the inability to automatically remove the packaging material in the current situation.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A powder packaging sealing heat-sealing and pressing machine includes a main body frame, a cylinder and a sealing pressing block. The cylinder is arranged at the top of the main body frame, the sealing pressing block is arranged at the lower end of the cylinder, a limiting rod is arranged at the side end of the main body frame, and a spring is arranged around the limiting rod.

[0007] A fixed-end magnetic ring is provided at the bottom of the sealing block, a heating pressure block is provided below the sealing block, a lifting bracket is provided inside the heating pressure block, and a temperature control heater is provided on the side of the heating pressure block.

[0008] The heating pressure block also includes a columnar groove, a limiting groove, and a heating wire. The columnar groove is formed inside the heating pressure block, the limiting groove is formed on the inner wall end face of the columnar groove, and the heating wire is inserted into the heating pressure block.

[0009] As a preferred technical solution of this utility model, the columnar groove is provided in two sets, and the center position is in the same longitudinal axis region as the fixed end magnetic ring, and the end of the heating wire is inserted into the temperature control heater.

[0010] As a preferred technical solution of this utility model, the lifting bracket further includes a connecting column, a movable end magnetic ring, and a positioning ring. The single structure of the lifting bracket is an inverted trapezoidal structure, and its shape matches the outer edge of the middle part of the sealing block.

[0011] As a preferred embodiment of this utility model, the connecting column is provided in two sets and is fixedly connected to the ends of both sides of the lifting bracket. The movable end magnetic ring is fixedly connected to the top of the connecting column, and the positioning ring is sleeved on the bottom of the connecting column.

[0012] As a preferred embodiment of this utility model, the connecting column is inserted into the columnar groove, the lifting bracket is embedded in the heating pressure block, and the upper end of this part is connected to the outside of the heating pressure block.

[0013] As a preferred technical solution of this utility model, the main frame is in the shape of a "door" with its bottom two sides bent inward at 90°. Two sets of limiting rods are provided and run through the top and bottom of the main frame.

[0014] In a preferred embodiment of this invention, the diameter of the limiting groove is smaller than that of the positioning ring, and the diameter of the columnar groove is larger than that of the positioning ring.

[0015] Compared with the prior art, this utility model provides a powder packaging sealing heat sealing and pressing machine, which has the following beneficial effects:

[0016] A powder packaging heat-sealing and pressing machine comprises a fixed-end magnetic ring, a heating pressure block, a lifting bracket, a movable-end magnetic ring, a columnar groove, and a limiting groove. In operation, a temperature-controlled heater heats a heating wire, which then conducts heat to the upper end of the heating pressure block. The package to be sealed is placed flat on top of the heating pressure block, and a cylinder applies pressure to the sealing block. As the sealing block moves downward, it compresses a spring until the packaging material is tightly sealed, and the heated packaging seals adhere to each other. After heat pressing, the spring returns, causing the sealing block to move upward and reset. During this process, because the fixed-end magnetic ring attracts the movable-end magnetic ring when pressed down, the lifting bracket is also pulled out when the sealing block moves upward, lifting the packaging material off the upper surface of the heating pressure block. Until the limiting ring at the bottom of the connecting column contacts the limiting groove and is intercepted by the limiting groove, the magnetic ring at the movable end and the magnetic ring at the fixed end are disconnected from each other, and the lifting bracket falls down and embeds into the heated pressure block to complete the reset.

[0017] Through the above settings and processes, this structure, compared to existing packaging sealing heat-sealing machines, can automatically position and reset the packaging material after heat pressing by incorporating a lifting bracket and the coordinated action of a fixed-end magnetic ring and a movable-end magnetic ring. This prevents the plastic packaging material from melting and sticking together due to prolonged exposure to high temperatures, thereby improving the continuity and stability of the heat-pressing process.

[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] In this embodiment: a powder packaging sealing heat sealing and pressing machine includes a main frame 1, a cylinder 2, and a sealing block 3. The cylinder 2 is located at the top of the main frame 1, the sealing block 3 is located at the lower end of the cylinder 2, a limit rod 5 is provided on the side end of the main frame 1, and a spring 6 is provided around the limit rod 5.

[0025] A fixed-end magnetic ring 4 is provided at the bottom of the sealing block 3, a heating pressure block 7 is provided below the sealing block 3, a lifting bracket 8 is provided inside the heating pressure block 7, and a temperature control heater 9 is provided on the side of the heating pressure block 7.

[0026] The heating pressure block 7 also includes a columnar groove 701, a limiting groove 702, and a heating wire 703. The columnar groove 701 is formed inside the heating pressure block 7, the limiting groove 702 is formed on the inner wall end face of the columnar groove 701, and the heating wire 703 is inserted into the heating pressure block 7.

[0027] In this embodiment, two sets of columnar grooves 701 are provided, and the center position is in the same longitudinal axis region as the fixed end magnetic ring 4. The end of the heating wire 703 is inserted into the temperature control heater 9. The lifting bracket 8 also includes a connecting column 801, a movable end magnetic ring 802 and a positioning ring 803. The single structure of the lifting bracket 8 is an inverted trapezoidal structure, and its shape matches the outer edge of the middle part of the sealing block 3.

[0028] Specifically, such as Figure 1 and Figure 3 As shown, the inverted trapezoidal shape of the lifting bracket 8 matches the middle of the sealing block 3, and can be completely embedded inside the heating pressure block 7 when the sealing block 3 is pressed down, preventing damage from additional pressure.

[0029] In this embodiment, two sets of connecting columns 801 are provided and are fixedly connected to the ends of both sides of the lifting bracket 8. The movable end magnetic ring 802 is fixedly connected to the top of the connecting column 801, and the positioning ring 803 is sleeved on the bottom of the connecting column 801. The connecting column 801 is inserted into the columnar groove 701, and the lifting bracket 8 is embedded in the heating pressure block 7, and the upper end of this part is connected to the outside of the heating pressure block 7.

[0030] Specifically, such as Figure 2 and Figure 4As shown, the movable end magnetic ring 802 is located at the top of the connecting column 801. When the sealing block 3 moves down, it can make the fixed end magnetic ring 4 come into contact with it and attract each other.

[0031] In this embodiment, the main frame 1 has an overall "door" shaped structure, with its bottom two sides bent inward at 90°. Two sets of limiting rods 5 are provided and pass through the top and bottom of the main frame 1. The diameter of the limiting groove 702 is smaller than that of the positioning ring 803, and the diameter of the columnar groove 701 is larger than that of the positioning ring 803.

[0032] The working principle and usage process of this utility model are as follows: When using this structure, the heating wire 703 is heated by the temperature-controlled heater 9, and the heat is conducted to the upper end of the heating pressure block 7. The sealing area of ​​the package to be sealed is placed flat on top of the heating pressure block 7. Then, the cylinder 2 applies pressure to the sealing block 3. As the sealing block 3 moves downward, it compresses the spring 6 until the sealing area of ​​the packaging material is pressed tightly, and the heated packaging sealing areas adhere to each other. After the heat pressing is completed, the spring 6 rebounds, causing the sealing block 3 to move upward and reset. During this process, because the fixed end magnetic ring 4 attracts the movable end magnetic ring 802 when it is pressed down, the lifting bracket 8 is also brought out when the sealing block 3 moves upward, lifting the packaging material on the heating pressure block 7 and causing it to detach from the upper surface of the heating pressure block 7. Until the positioning ring 803 at the bottom of the connecting column 801 comes into contact with the limiting groove 702 and is intercepted by the limiting groove 702, the movable end magnetic ring 802 and the fixed end magnetic ring 4 are disconnected from each other, and the lifting bracket 8 falls and embeds into the heating pressure block 7 to complete the reset.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
