Description

Technical Field

[0001] The invention relates to the technical field of sealing equipment, and in particular to a sealing equipment. Background Art

[0002] At a time when packaging technology is continuously innovating, non-woven bags have become an ideal choice for electronic product packaging due to their unique advantages. Non-woven bags are made of non-woven fabrics. As a new generation of environmentally friendly materials, they are not only moisture-proof, breathable, flexible and lightweight, but also non-combustible, easy to decompose, non-toxic and non-irritating, colorful, low-priced and recyclable. With these characteristics, non-woven bags can provide reliable protection for electronic products during transportation and storage, effectively avoiding physical damage.

[0003] At present, in order to meet the sealing needs of non-woven bags, the common sealing equipment on the market is generally composed of a support table and a sealing drive unit. A positioning table is slidably arranged on the support table, and a placement slot is provided on the positioning table. The sealing drive unit is used to perform the sealing operation on the non-woven fabric. When performing the non-woven fabric sealing operation, the operator needs to fold the non-woven fabric in half first, then place the folded non-woven fabric in the placement slot, and then start the sealing drive unit to seal the openings on both sides of the non-woven fabric, thereby making a non-woven bag. However, this technical solution has obvious defects. Since the non-woven fabric material is relatively soft, the non-woven fabric is very easy to move during the sealing process, which greatly reduces the sealing effect and cannot meet the requirements of high-quality sealing. Summary of the invention

[0004] The present invention aims to provide a sealing device to effectively solve the problem in the prior art that the non-woven fabric material is soft and easy to move during the sealing process, resulting in poor sealing effect.

[0005] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a sealing device, including a support table and a sealing drive unit, a positioning table is slidably arranged on the support table, and a placement groove for placing non-woven fabric is arranged on the positioning table; a positioning detection unit is arranged in the placement groove, and the positioning detection unit includes a detection piece; a plurality of No. 1 positioning holes are opened in the placement groove, and a plurality of No. 2 positioning holes are opened on the non-woven fabric, and the aperture of the No. 2 positioning hole is larger than the aperture of the No. 1 positioning hole; the detection piece can pass through the No. 2 positioning hole and be detachably connected to the positioning table, so as to position the non-woven fabric on the positioning table, and at the same time, the detection piece can detect the coaxiality of the No. 2 positioning hole and the detection piece; the sealing drive unit is used to perform sealing operations on the positioned non-woven fabric.

[0006] The beneficial effect of this solution is as follows: when performing the non-woven fabric sealing operation, the operator first folds the non-woven fabric in half to ensure that the No. 2 positioning holes on the opposite sides are aligned with each other. Then, the folded non-woven fabric is placed in the placement groove so that the No. 2 positioning hole corresponds to the No. 1 positioning hole one by one. Then, the detection piece is passed through the No. 2 positioning hole and smoothly inserted into the No. 1 positioning hole, thereby completing the positioning operation of the non-woven fabric. Thanks to the detection part's ability to detect the coaxiality of the No. 2 positioning hole with itself, operators can intuitively and accurately determine the positioning status of the non-woven fabric. Once it is found that the No. 2 positioning hole is not coaxial with the detection part, the position of the non-woven fabric can be adjusted in time until the two are coaxial, thereby greatly improving the accuracy of positioning. This precise positioning effectively avoids the displacement phenomenon that occurs during the sealing process due to the positioning deviation of the non-woven fabric, laying a solid foundation for high-quality sealing. In the positioning process, the design of the aperture of the No. 2 positioning hole being larger than the aperture of the No. 1 positioning hole in this technical solution plays a key role. If the aperture of the No. 2 positioning hole is slightly smaller than the aperture of the No. 1 positioning hole, the detection piece will inevitably encounter a jam when passing through the No. 2 positioning hole, and the insertion operation will be extremely difficult, which will not only seriously reduce the positioning efficiency, but also very likely cause the non-woven fabric to tear, affecting the product quality. If the aperture of the No. 2 positioning hole is equal to the aperture of the No. 1 positioning hole, it is extremely difficult to ensure that the two are completely concentric during the alignment process. Once they are not concentric, when the detection piece is inserted, the non-woven fabric at the edge of the No. 2 positioning hole can easily be brought into the No. 1 positioning hole, which will cause wrinkles and affect the appearance and sealing quality of the non-woven bag. This reasonable aperture difference design in this solution allows the detection piece to easily pass through the No. 2 positioning hole and be inserted into the No. 1 positioning hole, effectively avoiding the above-mentioned problems, ensuring the smooth positioning operation, and greatly improving production efficiency and product quality. After the positioning is completed and it is confirmed that the No. 2 positioning hole is coaxial with the detection part, the sealing drive unit is started to seal the openings on both sides of the non-woven fabric at the same time, and the non-woven bag is efficiently produced. The whole process is easy to operate and the positioning is accurate, which effectively solves the problem of poor sealing effect caused by the soft and easy movement of non-woven fabrics in the existing technology, and significantly improves the practicality and reliability of non-woven bag sealing equipment. Furthermore, the detection member includes a positioning rod and a detection rod which are connected in sequence, the positioning rod is tapered and is adapted to the No. 1 positioning hole.

[0007] The beneficial effects of this solution are as follows: In this technical solution, the positioning rod is conical and fits the No. 1 positioning hole. In the process of inserting the detection piece, it can reduce the influence of human and placement deviation, reduce the deviation of non-woven fabric, and lay a solid and stable foundation for sealing. Precise positioning ensures that when the sealing drive unit is operating, the sealing position is accurate and the sealing line is neat, effectively avoiding the problem of sealing deviation and looseness, greatly improving the quality of non-woven bag products, reducing the defective rate and cost, and enhancing the market competitiveness of products.

[0008] Furthermore, a detection ring is fixedly connected to the detection rod, the outer diameter of the detection ring is equal to the aperture of the No. 2 positioning hole, and the detection ring can detect the coaxiality of the No. 2 positioning hole and the detection rod.

[0009] The beneficial effects of this solution are as follows: a detection ring with an outer diameter equal to the diameter of the No. 2 positioning hole is connected to the detection rod, which can accurately detect the coaxiality of the No. 2 positioning hole and the detection rod. When the detection rod passes through the No. 2 positioning hole, if the two are not coaxial, there will be an uneven gap between the detection ring and the wall of the No. 2 positioning hole. The operator can adjust the position of the non-woven fabric in time to ensure accurate positioning. Accurate positioning makes the position of the non-woven fabric stable during the sealing process, avoiding problems such as sealing offset and loose sealing caused by position deviation, thereby improving the sealing quality and yield rate of non-woven bags, reducing production costs, and enhancing the competitiveness of products in the market.

[0010] Furthermore, a plurality of pressing plates are fixedly connected to the detection ring, and the pressing plates can press the non-woven fabric.

[0011] The beneficial effects of this solution are as follows: Due to the setting of the pressing plate, this technical solution can press the non-woven fabric to be flatter. On the one hand, during the sealing process, the flat non-woven fabric can effectively avoid wrinkles at the sealing point, greatly improving the overall aesthetics and visual appeal of the non-woven bag, and enhancing the competitiveness of the product in the market. On the other hand, the flat sealing point can significantly improve the sealing performance, so that the non-woven bag can better resist the influence of the external environment during transportation and storage, and ensure the safety of internal electronic products. In addition, the pressing effect of the pressing plate reduces the poor sealing caused by the unevenness of the non-woven fabric, reduces the defective rate, and improves production efficiency. In large-scale production, this can not only save raw material costs, but also speed up production progress and create more economic benefits for the company. Moreover, stable sealing quality also helps to establish a good brand image for the company, win customer trust, and further expand market share.

[0012] Furthermore, the sealing drive unit includes a mounting frame and a connecting plate. The mounting frame is fixedly connected to the top of the workbench. A driving member is installed on the top of the mounting frame. The output shaft of the driving member passes through the top of the mounting frame and is fixedly connected to the connecting plate. Two sets of sealing devices are installed on the side of the connecting plate away from the driving member.

[0013] The beneficial effects of this solution are as follows: the sealing drive unit has a reasonable structural design. The mounting frame is firmly fixed on the top of the workbench, providing reliable support for the entire drive unit. The drive component is installed on the top of the mounting frame, and its output shaft is directly and fixedly connected to the connecting plate, so the power transmission is efficient and stable. Two sets of sealing equipment are installed on one side of the connecting plate, which can seal the openings on both sides of the non-woven fabric at the same time, greatly improving the sealing efficiency. Moreover, this structure is easy to operate and maintain, and the staff can easily inspect and debug the drive components and sealing equipment, effectively reducing the equipment failure rate, ensuring the continuity of production operations, and helping enterprises improve the production efficiency and output of non-woven bags.

[0014] Furthermore, a positioning block is fixedly connected to one side of the sealing device close to the detection ring, and the positioning block can contact the detection ring.

[0015] The beneficial effect of this solution is that in the actual operation scenario of the sealing equipment, even if the driving part can adjust the heat sealing equipment to descend, the fluctuation of the driving part's air source pressure, the continuous wear of the driving part, and the dynamic change of the load will interfere with the descent accuracy of the sealing equipment, causing deviations in the heat sealing position each time, affecting the sealing quality. In this solution, the positioning block set close to the side of the detection ring can effectively make up for the above shortcomings and bring significant advantages in many aspects.

[0016] (1) Ensure positioning accuracy: The positioning block provides a reference for accurate positioning of the sealing equipment. When the detection ring contacts the positioning block during the descent of the sealing equipment, the sealing equipment reaches the preset heat sealing position, which greatly reduces the position error caused by various interference factors and ensures that the position of each heat seal is highly consistent, thereby improving the consistency of heat sealing and ensuring the stability of sealing quality.

[0017] (2) Enhanced heat sealing stability: During the heat sealing process, the positioning block provides additional stable support for the sealing equipment. When the sealing equipment contacts the non-woven fabric and applies pressure, the sealing equipment is prone to shaking or shifting due to uneven force. The positioning block, with its stable structure, shares part of the pressure on the sealing equipment during operation, greatly reducing the amplitude of shaking and shifting. At the same time, the positioning block fits tightly with the detection ring, further limiting the displacement of the sealing equipment in the plane, so that the sealing equipment always remains stable during the heat sealing process, ensuring that the heat sealing pressure is evenly distributed at the non-woven fabric seal, improving the heat sealing quality, and reducing the sealing defect rate caused by unstable heat sealing.

[0018] (3) Improve production efficiency: The stable and precise heat sealing process reduces the rework caused by heat sealing quality problems, greatly improves production efficiency, helps enterprises achieve efficient production, and enhances market competitiveness.

[0019] Furthermore, a driving unit is also provided on the supporting platform, and the driving unit is used to drive the positioning platform to move.

[0020] The beneficial effect of this solution is that the clever setting of the drive unit can drive the positioning table to move flexibly between different workstations. This feature makes the operator more convenient and efficient when performing sealing operations, greatly improves the convenience of operation, helps to improve production efficiency, and meet diverse production needs.

[0021] Furthermore, the driving unit includes a power component, which is installed on a support platform. A screw rod is fixedly connected to the output shaft of the power component, a nut is fixedly connected to the bottom of the positioning platform, the screw rod and the nut are threadedly connected, a slider is fixedly connected to the bottom of the positioning platform, a slide rail is fixedly connected to the support platform, and the slider is slidably set on the slide rail.

[0022] The beneficial effects of this solution are as follows: This technical solution greatly improves the reliability and accuracy of the movement of the positioning table through the coordinated design of the power component, screw rod, nut, slider and slide rail. The power component is installed on the support table to provide a stable power source for the entire drive system. When the power component is started, its output shaft drives the screw rod to rotate, and the nut threadedly connected to the screw rod can accurately drive the positioning table to move under the drive of the screw rod. The slider at the bottom of the positioning table cooperates with the slide rail on the support table to provide guidance for the movement of the positioning table and ensure that it slides smoothly along a straight line. This precise and stable movement of the positioning table allows the non-woven fabric to reach the predetermined position quickly and accurately before sealing, thereby improving production efficiency and ensuring the consistency of sealing quality.

[0023] Furthermore, limiting plates are fixedly connected to opposite sides of the positioning platform, and a side of the limiting plate close to the placement slot extends to above the placement slot.

[0024] The beneficial effects of this solution are as follows: the setting of the limit plate in this technical solution brings many advantages. The gap formed between the placement groove and the limit plate provides an accurate and convenient operating space for the placement of the non-woven fabric. When sealing the non-woven bag, placing the opposite sides of the non-woven fabric in the gap can effectively prevent the edge of the non-woven fabric from curling up, ensuring that the edge of the non-woven fabric always remains flat during the sealing process, improving the sealing quality and product qualification rate of the non-woven bag, and enhancing the competitiveness of the product in the market.

[0031] like Figure 1 and Figure 2As shown, the sealing drive unit includes a mounting frame 14, a driving member 15 and a connecting plate 16. The mounting frame 14 is welded to the top of the support platform 1. The driving member 15 is installed on the top of the mounting frame 14 by bolts. The output shaft of the driving member 15 passes through the top of the mounting frame 14 and is connected to the connecting plate 16 by bolts.
