Description

Technical Field

[0001] This utility model relates to the field of sealing equipment technology, specifically to a sealing machine. Background Technology

[0002] In today's packaging industry, non-woven bags have been widely used in the outer packaging of electronic products due to their significant advantages. Made from non-woven fabric, a new generation of environmentally friendly material, non-woven bags are moisture-proof, breathable, flexible, lightweight, non-flammable, easily degradable, non-toxic, and non-irritating. They also come in a variety of colors, are inexpensive, and are recyclable, effectively protecting electronic products from physical damage.

[0003] Currently, existing nonwoven fabric sealing machines generally include a worktable with a sealing unit for sealing the nonwoven fabric. A positioning platform with a receiving groove is also mounted on the worktable. During the sealing operation, the nonwoven fabric is first folded in half, then placed in the receiving groove, and then the sealing unit is activated to seal the openings on opposite sides of the nonwoven fabric, thus completing the production of the nonwoven bag.

[0004] However, this traditional sealing machine technology has some problems that cannot be ignored. Non-woven fabric is inherently soft and prone to displacement during the sealing process, causing wrinkles at the seal of the non-woven bag. These wrinkles severely affect the overall aesthetics of the packaging, reducing the product's visual competitiveness in the market; furthermore, they may also reduce the sealing performance, weakening the protection for electronic products and failing to meet the high-quality packaging requirements of electronic products. Utility Model Content

[0005] The present invention aims to provide a sealing machine to solve the problem that existing sealing machines tend to produce wrinkles at the sealing point when sealing non-woven bags.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a sealing machine, comprising a worktable, a drive unit, and a sealing unit. A positioning table is slidably arranged on the worktable, and a receiving groove is provided on the positioning table. A positioning unit is provided in the receiving groove. The positioning unit can position the non-woven fabric. The drive unit is used to drive the positioning table to move on the worktable. The sealing unit is used to seal the non-woven fabric.

[0007] The beneficial effects of this solution are as follows: Compared with traditional sealing machines, the sealing machine provided by this technical solution has achieved significant technological advancements in many aspects, effectively solving the problem of wrinkles easily forming at the sealing point of non-woven bags in existing technologies.

[0008] (1) Avoiding sealing wrinkles and improving packaging aesthetics: By setting a positioning unit in the receiving slot, the positioning unit can accurately position the non-woven fabric when it is folded and placed in the receiving slot, greatly limiting the displacement of the non-woven fabric during the sealing process. This improvement effectively avoids the problem of wrinkles at the sealing point caused by the movement of the non-woven fabric, significantly improves the appearance quality of the non-woven bag, significantly enhances the visual competitiveness of the product in the market, and adds more attractiveness to the product packaging.

[0009] (2) Ensure sealing performance and enhance protection: Due to the setting of the positioning unit, the non-woven fabric remains stable during the sealing process, ensuring the flatness and integrity of the sealing area, thereby greatly improving the sealing performance of the sealing, enhancing the protection of electronic products, and meeting the strict requirements of high-quality packaging for electronic products.

[0010] (3) Optimize the operation process and improve work efficiency: With the help of the drive unit, the positioning table can be precisely driven to the bottom of the sealing unit to realize automated positioning and sealing operations. This design simplifies the originally complicated sealing process, reduces the links of manual adjustment and intervention, greatly improves production efficiency, reduces labor costs, and improves the stability and consistency of the production process.

[0011] In summary, the sealing machine provided by this technical solution, through the coordinated design of the positioning unit and the drive unit, fundamentally solves the problems encountered by existing sealing machines when sealing non-woven bags, bringing a more efficient and high-quality sealing solution to the packaging industry, and has significant practical value and broad market application prospects.

[0012] Furthermore, the drive unit includes a power component, which is mounted on the worktable. A lead screw is fixedly connected to the output shaft of the power component, and a nut is fixedly connected to the bottom of the positioning table. The lead screw and the nut are threaded together. A slider is fixedly connected to the bottom of the positioning table, and a slide rail is fixedly connected to the worktable. The slider is slidably mounted on the slide rail.

[0013] The beneficial effects of this solution are as follows: the output shaft of the power component is fixedly connected to the lead screw, ensuring efficient and stable power transmission. The precise rotation of the lead screw drives the nut, thereby driving the positioning table to move smoothly, realizing the movement of the positioning table between different work positions. The slider at the bottom of the positioning table cooperates with the slide rail on the worktable, which not only provides reliable guidance for the movement of the positioning table and prevents it from deviating during movement, but also greatly enhances the stability of the positioning table's movement, ensuring the continuity of the sealing operation.

[0014] Furthermore, the positioning unit includes a positioning component. The bottom of the receiving groove is provided with several No. 1 positioning holes, and the non-woven fabric is provided with several No. 2 positioning holes. The positioning component can pass through the No. 2 positioning holes and the No. 1 positioning holes to position the non-woven fabric.

[0015] The beneficial effects of this solution are as follows: This technical solution significantly enhances the accuracy and stability of positioning. When the non-woven fabric is placed in the receiving groove, the positioning component can pass through the second positioning hole on the non-woven fabric and fit tightly with the first positioning hole at the bottom of the receiving groove, forming a stable connection structure. Compared with the traditional method of relying solely on the receiving groove for positioning, this dual positioning design greatly reduces the possibility of displacement of the non-woven fabric during the sealing process, effectively reduces wrinkles at the sealing point, and significantly improves the appearance quality of the non-woven bag. At the same time, the operation of the positioning hole and the positioning component is simple, requiring no complicated procedures, and can quickly achieve positioning, greatly improving the efficiency of the overall sealing operation.

[0016] Furthermore, the positioning component is a positioning pin.

[0017] The advantages of this solution are: the positioning pin structure is simple and the operation is intuitive and convenient. When positioning non-woven fabric, workers can quickly insert it into the corresponding No. 1 and No. 2 positioning holes, greatly saving positioning time and improving overall work efficiency.

[0018] Furthermore, pressure plates are fixedly connected to both sides of the positioning platform, with the side of the pressure plate closest to the receiving groove extending above the receiving groove.

[0019] The beneficial effects of this solution are as follows: When sealing non-woven fabric, the fabric is first folded in half. Then, a pressure plate is used to hold down the two opposite open ends of the folded fabric, effectively preventing the edges of the non-woven fabric from curling up and ensuring that the edges remain flat throughout the sealing process.

[0020] When sealing non-woven fabric, first fold the fabric in half, then use the pressure plates fixed on both sides of the positioning platform to press down the two opposite open ends of the folded fabric. The structure where the pressure plates extend above the receiving groove effectively prevents the edges of the non-woven fabric from curling up during the sealing process, ensuring that it remains flat at all times. This not only prevents wrinkles caused by curling edges, improving the aesthetics of the non-woven bag, but also ensures even pressure distribution at the sealing area, enhancing the seal's tightness.

[0021] Furthermore, the sealing unit includes a support frame and a mounting plate. The support frame is fixedly connected to the top of the workbench, and a drive unit is mounted on the top of the support frame. The output shaft of the drive unit passes through the top of the support frame and is fixedly connected to the mounting plate. A sealing device is mounted on the side of the mounting plate away from the drive unit.

[0022] The beneficial effects of this solution are as follows: the support frame is firmly connected to the top of the workbench, forming a solid support system that greatly reduces shaking during the sealing process and significantly improves sealing accuracy. The output shaft of the drive unit is directly connected to the mounting plate, resulting in low power loss and enabling rapid and precise start and stop according to operating commands, effectively shortening the sealing time. The mounting plate carries the sealing equipment, facilitating the sealing of non-woven fabrics. Attached Figure Description
