Description

Technical Field

[0001] This utility model relates to a special hot pressing molding machine for PTFE fiber raw materials, belonging to the technical field of filter bag processing equipment. Background Technology

[0002] The PTFE fiber raw material-specific hot press molding machine is a device specifically designed for hot pressing the side seals of filter bags. It aims to achieve efficient and precise sealing operations, improving the production quality and efficiency of filter bags. This machine is widely used in filter bag production in industries such as environmental protection, chemical, food, and pharmaceuticals. It is suitable for filter bags of various materials, such as polyester fiber filter bags, polypropylene filter bags, and PTFE filter bags. It can meet the high-quality sealing requirements of different industries, providing strong support for enterprises to improve production efficiency, reduce costs, and enhance product competitiveness.

[0003] A PTFE filter bag, with Chinese patent number CN206414887U, belongs to the field of dust collector filter bag technology. The PTFE filter bag includes a bag body, which is made of multiple layers of composite material stitched together. The stitches of the bag body have needle-hole seams, and PTFE sealing strips are heat-pressed onto the needle-hole seams. Compared with existing technologies, this invention has the advantages of high filtration accuracy and good dust removal efficiency, and is especially suitable for filtering PM2.5 dust, achieving an effective filtration rate of 99.99%.

[0004] However, when the thermoforming machine is operating at the side sealing of the filter bag, the material conveying roller shaft cannot deform and cannot properly adapt to the side sealing of the filter bag of different dimensions. Workers need to spend more time and effort to adjust the position of the filter bag during feeding to ensure that it can pass through the material conveying roller shaft accurately. This greatly reduces the feeding speed and thus affects the production efficiency of the entire thermoforming machine.

[0005] To address this, a special hot pressing molding machine for PTFE fiber raw materials is proposed. Utility Model Content

[0006] In view of this, the present invention provides a special hot pressing molding machine for PTFE fiber raw materials to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.

[0007] The technical solution of this utility model is implemented as follows: A special hot pressing molding machine for PTFE fiber raw materials includes an operating table. A weighing upright is fixedly connected to the upper end of the horizontal surface of the operating table. A connecting inner shaft is fixedly connected to the upper end of the weighing upright. An inner support deformation component is provided at the outer end of the connecting inner shaft. An external deformable roller assembly is installed on the outer side of the inner support deformation component. The inner support deformation component includes a hollowed-out adapter front plate. The front end of the hollowed-out adapter front plate has four arc-shaped slots. An extension strip is slidably connected to the inner end of the arc-shaped slot. A motor is connected to the inner support deformation component. An outwardly pushable T-shaped rod is fixedly connected to the side of the extension strip away from the arc-shaped slot. The external deformable roller assembly includes multiple self-adaptive strips and corrugated deformable strips.

[0008] More preferably, the push-out T-shaped rod extends outward from the outer side of the arc-shaped slot, and multiple push-out T-shaped rods are respectively located around the outer perimeter of the inner support deformation component.

[0009] More preferably, the multiple adaptive strips and corrugated deformable strips are arranged in a ring-shaped interval, and the positions of the multiple adaptive strips respectively abut against each other with the push-out T-shaped rod.

[0010] More preferably, the external deformable roller assembly has a pair of slots arranged front and rear, and the inner end of the slots is rotatably connected to a bottom hot-pressing roller.

[0011] More preferably, a pair of top hot-pressing rollers are rotatably connected to the horizontal front side of the worktable, and both the bottom hot-pressing rollers and the top hot-pressing rollers are externally connected to a drive motor.

[0012] More preferably, the top hot press roller is located directly above the bottom hot press roller, and an auxiliary alignment line is fixedly connected to the upper end of the external deformable roller assembly.

[0013] More preferably, the auxiliary alignment line is located at the center line of the uppermost adaptive strip, and the end of the outward-pushing T-shaped rod away from the hollowed-out adapter front plate is fixedly connected to an anti-slip abutment layer.

[0014] More preferably, the anti-slip outer layer is in contact with the inner sidewall of the adaptive strip, and a control panel is fixedly connected to the horizontal front side of the operating table.

[0015] The present invention has the following advantages due to the adoption of the above technical solution:

[0016] I. This solution also includes an inner support deformation component installed in the connecting inner shaft within the external deformable roller assembly. This allows the outer diameter of the external deformable roller assembly to be adapted to the winding dimension of the fiber filter bag raw material sheet to be processed. When facing filter bags with different side sealing dimensions, the deformable external deformable roller assembly can quickly adjust its shape without requiring workers to perform complex adjustment operations. This significantly shortens the feeding preparation time, thereby improving overall production efficiency. Workers do not need to laboriously adjust the filter bag to adapt to the external deformable roller assembly when feeding, reducing the difficulty and complexity of operation.

[0017] Second, an auxiliary alignment line is set at the central axis position on the external deformable roller assembly. The auxiliary alignment line corresponds to the interface at both ends of the winding of the fiber filter bag raw material sheet. This allows the workers to make the alignment between the interface at both ends of the winding of the fiber filter bag raw material sheet and the bottom and top hot pressing rollers more accurate. At the same time, the anti-slip abutment outer layer corresponds to the position of the inner side wall of the adaptive strip in the external deformable roller assembly. This allows the anti-slip abutment outer layer to improve the tightness of the connection between the outward push T-shaped rod and the inner side wall of the adaptive strip when they are in contact, making the deformation state of the external deformable roller assembly more stable.

[0026] In the following description, only certain exemplary embodiments are briefly described.

Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] Example 1

[0029] like Figure 1-5 As shown, this utility model embodiment provides a special hot pressing molding machine for PTFE fiber raw materials, including an operating table 1. A weighing pole 2 is fixedly connected to the upper end of the horizontal surface of the operating table 1. A connecting inner shaft 3 is fixedly connected to the upper end of the weighing pole 2. An inner support deformation assembly 11 is provided at the outer end of the connecting inner shaft 3. An external deformable roller shaft assembly 4 is installed on the outer side of the inner support deformation assembly 11. The inner support deformation assembly 11 includes a hollowed-out adapter front plate 16. The front end of the hollowed-out adapter front plate 16 has four arc-shaped slots 13. An extension strip 14 is slidably connected to the inner end of the arc-shaped slots 13. A motor 12 is connected to the inner support deformation assembly 11. An outwardly pushable T-shaped rod 15 is fixedly connected to the side of the extension strip 14 away from the arc-shaped slots 13. The external deformable roller shaft assembly 4 includes multiple adaptive strips 5 and corrugated deformable strips 6.

[0030] The outwardly pushable T-shaped rod 15 extends outward from the outer side of the arc-shaped slot 13. Multiple outwardly pushable T-shaped rods 15 are located around the outer perimeter of the inner support deformation assembly 11. Multiple adaptive strips 5 and corrugated deformable strips 6 are arranged in a ring-shaped interval. The positions of the multiple adaptive strips 5 are respectively abutting against the outwardly pushable T-shaped rods 15. A pair of slots 7 are provided on the outer deformable roller assembly 4. The inner end of the slot 7 is rotatably connected to the bottom hot pressure roller 8. A pair of top hot pressure rollers 9 are rotatably connected to the front side of the horizontal face of the operating table 1. Both the bottom hot pressure roller 8 and the top hot pressure roller 9 are externally connected to drive motors. The top hot pressure roller 9 is located directly above the bottom hot pressure roller 8. A control panel 18 is fixedly connected to the front side of the horizontal face of the operating table 1.

[0031] Example 2

[0032] like Figure 1 , 4 As shown in Figure 5, in one embodiment, an auxiliary alignment line 10 is fixedly connected to the upper end of the external deformable roller assembly 4. The auxiliary alignment line 10 is located at the center line of the uppermost adaptive strip 5. An anti-slip abutment outer layer 17 is fixedly connected to the end of the push-out T-shaped rod 15 away from the hollowed-out adapter front plate 16. The anti-slip abutment outer layer 17 is in contact with the inner wall of the adaptive strip 5.

[0033] By setting an auxiliary alignment line 10 at the central axis position on the external deformable roller shaft assembly 4, and having the auxiliary alignment line 10 correspond to the interface at both ends of the winding of the fiber filter bag raw material sheet, the alignment between the interface at both ends of the winding of the fiber filter bag raw material sheet and the bottom hot pressure roller 8 and the top hot pressure roller 9 can be more accurate during operation, making the operation process simpler. At the same time, when the externally pushable T-shaped rod 15 is pushed outward to deform the external deformable roller shaft assembly 4, the anti-slip abutment outer layer 17 set on the externally pushable T-shaped rod 15 can correspond to the position of the inner side wall of the adaptive strip 5 in the external deformable roller shaft assembly 4. When the externally pushable T-shaped rod 15 and the inner side wall of the adaptive strip 5 are in contact, the anti-slip abutment outer layer 17 can improve the tightness of the connection between the two, making the deformation state of the external deformable roller shaft assembly 4 more stable.

[0034] In operation, this invention involves winding the fiber filter bag material sheet around the outer side of the external deformable roller assembly 4. The two ends of the wound fiber filter bag material sheet are parallel to each other, extending between the top and bottom hot-pressing rollers 9 and 8. The top and bottom hot-pressing rollers 9 and 8 are used to heat-press the side interfaces together. The external deformable roller assembly 4 also includes an inner support deformation assembly 11 installed in the connecting inner shaft 3. The inner support deformation assembly 11 can be driven by the motor 12 to rotate the hollowed-out adapter front plate 16, causing the extension strip 14 to move along the arc-shaped path within the arc-shaped slot 13. This allows the outwardly pushable T-shaped rod 15 outside the extension strip 14 to move along the center point of the inner support deformation assembly 11, etc. At different distances from the outward extension, the outward extension of the T-shaped rod 15 allows the adaptive strip 5 in the external deformable roller assembly 4 to expand synchronously. At this time, the corrugated deformable strips 6 set at intervals outside the adaptive strip 5 can also expand outward, so that the outer diameter of the external deformable roller assembly 4 can be adapted to the winding dimension of the fiber filter bag raw material sheet to be processed. When facing the side sealing of filter bags of different dimensions, the deformable external deformable roller assembly 4 can quickly adjust its own shape without the need for workers to perform complicated adjustment operations, which greatly shortens the feeding preparation time and improves the overall production efficiency. Workers do not need to laboriously adjust the filter bag to adapt to the external deformable roller assembly 4 when feeding, which reduces the difficulty and complexity of operation.

[0035] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
