[0004] The hot pressing equipment manually controls the pressing time of the hot pressing plate on the non-woven fabric. Since the pressing time of each person is different, the hot pressing effect of different non-woven fabrics is also different, which affects the quality of the non-woven fabrics and makes the quality of the non-woven fabrics uneven. Summary of the Invention

[0005] In order to improve the problem of different hot pressing effects on different non-woven fabrics, the present application provides a non-woven fabric hot pressing device.

[0006] The present application provides a non-woven fabric hot pressing device, which adopts the following technical solution:

[0007] A non-woven fabric hot pressing device includes a base, a movable structure is provided on the base, the movable structure is used to drive the non-woven fabric to move, a hot pressing roller is provided on the base, the hot pressing roller includes a hot pressing strip and an extrusion strip, the hot pressing strip and the extrusion strip together form a ring, the hot pressing strip can perform hot pressing treatment on the non-woven fabric, and a rotating structure is provided on the base, the rotating structure is used to drive the hot pressing roller to rotate.

[0008] By adopting the above technical solution, a ring is formed by the hot pressing strips and the extrusion strips, one side of the hot pressing roller is the hot pressing strip, and the other side of the hot pressing roller is the extrusion strip. In addition, the hot pressing strips can perform hot pressing treatment on the non-woven fabric, and the rotating structure drives the hot pressing roller to rotate, so that the hot pressing strips can perform hot pressing treatment on the non-woven fabric, and the extrusion strips can extrude the non-woven fabric, so that the non-woven fabric can cool, so that the time for the hot pressing strips in the hot pressing roller to perform hot pressing treatment on the non-woven fabric is limited, so that the hot pressing time of different non-woven fabrics is the same, so that the hot pressing effects of different non-woven fabrics are the same, and different non-woven fabrics have the same hot pressing effect, thereby enabling the non-woven fabric to be hot pressed more stably; since a movable structure is provided on the base, the movable structure can drive the non-woven fabric to move, so that the non-woven fabric can move on the base, ensuring that the non-woven fabric passes through the hot pressing roller for the same time, reducing the different hot pressing effects caused by the different times the non-woven fabrics pass through the hot pressing roller.

[0009] Optionally, the base is provided with a fixing bar, the fixing bar is provided with a plurality of fixing grooves, the hot pressing roller is provided with a plurality of fixing rods that can be inserted into the fixing grooves, the fixing bar is provided with a locking assembly, and the locking assembly can limit the fixing rod from being separated from the fixing groove.

[0010] By adopting the above technical solution, the fixing rod is inserted into the fixing groove, so that multiple hot pressing rollers can move on the fixed strip, and the rotating structure can rotate the multiple hot pressing rollers, so that the multiple hot pressing rollers can perform hot pressing treatment on the non-woven fabric, so that the non-woven fabric can be hot pressed in time by the hot pressing roller, so that the non-woven fabric can be stably hot pressed when passing through the hot pressing roller, and the locking component limits the fixing rod from being disengaged from the fixing groove, so that the hot pressing roller can be stably located on the fixed strip, thereby improving the stability of the rotation of the hot pressing roller in the fixed strip; when the locking component is released from the fixing rod, the hot pressing roller can be replaced, so that the ratio between the hot pressing strip and the extrusion strip can be changed, so that the non-woven fabric can have different hot pressing times.

[0011] Optionally, the locking assembly includes a locking plate, which is slidably connected to the fixing bar, and a through hole is provided on the end face of the locking plate for the fixing rod to pass through, a locking block is provided on the wall of the through hole, and a locking groove is provided on the fixing rod, and when the locking block is inserted into the locking groove, the fixing rod is located in the fixing groove.

[0012] By adopting the above technical solution, the staff first inserts the fixing rod into the fixing groove, and then slides the locking plate on the fixing strip, so that the fixing rod slides in the perforation until the locking block is inserted into the locking groove. At this time, the locking block is restricted by the locking groove wall, making it difficult to remove the fixing rod from the fixing groove, so that the fixing rod can be fixed in the fixing groove, allowing the hot pressing roller to be stably located in the fixing strip.

[0013] Optionally, the locking assembly further includes a card block, which is arranged on the locking plate, and a sliding groove for sliding the locking plate is provided on the fixing bar, and a card slot is provided on the groove wall of the sliding groove. When the card block is inserted into the card slot, the locking block is located in the locking groove.

[0014] By adopting the above technical solution, the card block is inserted into the card slot, making it difficult for the locking plate to slide in the slide slot, so that the locking plate can be stably located in the slide slot, that is, the locking plate can be fixed. Since the locking block is located in the locking slot, the possibility of the locking block escaping from the locking slot is reduced, so that the locking block can stably restrict the fixing rod.

[0015] Optionally, a placement plate is provided on the base, and a plurality of rotation holes are opened on the placement plate. The hot pressing roller can pass through the rotation holes, and the hot pressing roller can rotate in the rotation holes.

[0016] By adopting the above technical solution, the hot pressing roller rotates in the rotating hole, so that the side of the hot pressing roller away from the fixed rod can be supported by the placement plate, so that both sides of the hot pressing roller can be more stable, so that the hot pressing roller can stably perform hot pressing treatment on the non-woven fabric, and increase the stability of the hot pressing roller in the hot pressing treatment of the non-woven fabric; the hot pressing roller can pass through the rotating hole, so that the hot pressing roller can be taken out from one side of the placement plate, that is, the fixed rod can be detached from the fixed groove from one side of the placement plate.

[0018] By adopting the above technical solution, the sliding plate slides in the sliding hole, and the limiting component limits the sliding plate, so that the sliding plate can be stably located in the sliding hole, so that the distance between the fixed bar and the placement plate is fixed, so that the staff can adjust the distance between the fixed bar and the placement plate, and then non-woven fabrics of different widths can be hot-pressed. When hot-pressing non-woven fabrics of different widths, there is no need to use additional hot-pressing equipment, thereby reducing the cost of hot-pressing non-woven fabrics of different widths.

[0019] Optionally, the limiting assembly includes a limiting rod, which is rotatably connected to the support plate. A plurality of limiting grooves are provided on the sliding plate, and the plurality of limiting grooves are distributed along the sliding plate toward the support plate. When the limiting rod is inserted into the limiting groove, the sliding plate can be fixed in the sliding hole.

[0020] By adopting the above technical solution, the limiting rod slides on the support plate, so that the limiting rod can be inserted into the limiting groove, so that the sliding plate is fixed in the sliding hole, limiting the movement of the sliding plate, so that the distance between the fixed strip and the placement plate is fixed to each other; a plurality of limiting grooves are provided on the sliding plate, and the plurality of limiting grooves are distributed along the direction of the sliding plate toward the support plate, and when the limiting rod is inserted into different limiting grooves, the distance between the support plate and the fixed strip can be different, so that the distance between the fixed strip and the support plate can be adjusted to adapt to non-woven fabrics of different widths.

[0021] Optionally, a connecting hole is provided on the groove wall of the fixing groove, a linkage rod is provided in the connecting hole, the connecting hole is connected to multiple limiting grooves, and a connecting hole is provided on the limiting rod; when the fixing rod is inserted into the fixing groove, the linkage rod can move from the connecting hole to the limiting groove, and at this time the limiting rod is located in the limiting groove.

[0022] By adopting the above technical solution, the fixing rod is inserted into the fixing groove, and the fixing rod abuts the linkage rod, allowing the linkage rod to move in the linkage hole. Since the linkage hole is connected to multiple restriction grooves, the linkage rod can be inserted into the linkage hole, making it difficult for the restriction rod to escape from the restriction groove, allowing the restriction rod to restrict the sliding plate. When the fixing rod is inserted into the fixing groove, the distance between the fixing bar and the support plate can be more stable, thereby making the support plate and the fixing bar firm, so that the hot pressing roller can be stably located between the support plate and the fixing bar when the non-woven fabric is hot pressed, allowing the hot pressing roller to stably perform hot pressing on the non-woven fabric.

[0023] Optionally, a pop-up spring is provided on the linkage rod, and the pop-up spring is arranged in the linkage hole, and the pop-up spring drives the linkage rod to disengage from the linkage hole.

[0024] By adopting the above technical solution, a pop-up spring is set in the connecting hole, so that the pop-up spring can be deformed in the connecting hole. When the fixed rod is out of the fixed groove, the pop-up spring can drive the linkage rod to disengage from the linkage hole, so that the linkage rod does not restrict the limiting rod, allowing the limiting rod to disengage from the limiting groove, thereby allowing the staff to slide the sliding plate in the sliding hole, so that the distance between the support plate and the fixed bar can be adjusted.

[0025] Optionally, the rotating structure includes a rotating belt and a driving member, the rotating belt is arranged on the fixed groove, and the driving member can drive the rotating belt to rotate.
