Fig. 1 shows an automatic winding device 100 for prepreg tape provided by the present invention, which can wind and scald the prepreg tape. The automatic winding device 100 includes a machine base 1 supported on the floor or a pedestal, a storage mechanism capable of temporarily storing the prepreg tape, a reel changing mechanism having winding and roll changing functions, a scalding mechanism for scalding the prepreg tape, a floating mechanism, and a controller 6 (see fig. 8) serving as a control center of the automatic winding device 100.

The housing 1 is made of a rigid material. The machine base 1 is provided with a rotatable feed roll 11, a movable base 12 which can move forward and backward, a plurality of traction rolls 13 which are rotatably supported on the movable base 12, and a moving motor 14 (see fig. 3) for driving the movable base 12 to move. A plurality of slide rails (not shown) extending in the front-rear direction are disposed on the machine base 1, and the movable base 12 is disposed on the top of the machine base 1 and slidably engaged with the slide rails. The feed roll 11 and each of the drawing rolls 13 extend in the left-right direction.

Referring to fig. 6-7, the automated winding device 100 defines a winding path for the prepreg tape, which passes through the feed roll 11 and the pull rolls 13 in a serpentine winding manner. The feed roll 11 is located at the most upstream of the winding path to adjust the starting position of the prepreg tape into the automatic winding apparatus 100.

Referring to fig. 1-3, the material storing mechanism includes a pair of guide rails 21 fixedly disposed on the frame 1, a pair of slide blocks 22 respectively slidably engaged with the pair of guide rails 21, a rotatable material storing roller 23 located on the winding path, and a pair of material storing air cylinders 24 drivingly connected to the material storing roller 23.

The pair of guide rails 21 are arranged opposite to each other in the left-right direction and extend in the vertical direction. Each storage cylinder 24 comprises a first cylinder body fixedly connected with the corresponding side guide rail 21 and a first cylinder shaft which can stretch and retract relative to the first cylinder body, and each first cylinder shaft is vertically arranged and fixedly connected with the sliding block 22 on the corresponding side so as to drive the sliding block 22 to move up and down along the corresponding guide rail 21. The stock roller 23 is adjacent to the downstream of the feed roller 11, and both side end portions thereof are rotatably connected to the slide blocks 22 on the respective sides, respectively, so that a pair of stock cylinders 24 can move the stock roller 23 up and down.

Referring to fig. 2 and fig. 6-7, the winding mechanism includes a pair of left and right rotating arms 51 extending forward and backward, a pair of winding rollers 52 disposed forward and backward, and a pair of limiting rollers 53 disposed on upper and lower sides of the pair of rotating arms 51. Each rotating arm 51 is configured to be supported on the base 1 rotatably around the middle part thereof; a pair of take-up rollers 52 are rotatably supported on the pair of rotating arms 51 and are away from each other; each of the stopper rollers 53 is configured to be rotatable around the same rotation center (i.e., the middle of the rotating arm 51) in synchronization with the pair of rotating arms 51.

When the automatic winding device 100 is operated, the winding roller 52 is located at the end of the winding path, and the prepreg tape is wound into a roll by the winding roller 52 on the front side. After the front wind-up roll 52 is fully wound, the pair of rotating arms 51 are driven by corresponding driving motors (not shown in the figure) to rotate, so that the wind-up rolls 52 on the front and rear sides are switched to continue winding. In this process, the stop roller 53 on the lower side is turned to the upper side and lifts the prepreg tape in contact, i.e., temporarily defining part of the take-up path, so that the heating wire 43 (see below) is in contact with the prepreg tape.

Referring to fig. 3 to 5, the floating mechanism includes a floating seat 31 rotatably installed inside the movable seat 12, a floating roller 32 rotatably supported at the front of the floating seat 31, and a pair of floating cylinders 33 provided at left and right sides. The dancer 32 is located on the winding path and adjacent to the upstream side of the front-side winding roller 52, and is used for pressing the prepreg tape on the winding roller 52 when the front-side winding roller 52 is initially wound and keeping a certain range of gap with the winding roll on the winding roller 52 during the winding process of the winding roller 52, so that the prepreg tape forms a larger wrap angle with the winding roller 52 to facilitate the winding of the prepreg tape.

Each floating cylinder 33 comprises a second cylinder fixedly arranged on the inner side of the moving seat 12 and a second cylinder shaft capable of extending and contracting relative to the second cylinder, and one end part of the second cylinder shaft, far away from the second cylinder, is rotatably connected with the rear part of the floating seat 31 so as to drive the floating seat 31 to rotate. It is understood that the movable base 12 can move the floating base 31, the floating roller 32 and the floating cylinder 33 back and forth together.

Referring to fig. 8, the controller 6 is connected with a pair of floating cylinders 33 through signals and can control the floating cylinders 33 to act so as to selectively control the floating rollers 32 to contact the winding rollers 52 on the front side; the controller 6 is in signal connection with the moving motor 14 and can control the moving motor 14 to rotate so as to adjust the gap between the floating roller 32 and the front winding roller 52. Further, the moving motor 14 is a servo motor and is coupled to the moving seat 12 by means of a transmission gear set to precisely control the gap between the dancer roller 32 and the corresponding wind-up roller 52.

Referring to fig. 1-4 and 8, the scalding mechanism includes a pair of crank arms 41 rotatably mounted on the movable base 12, a pair of crank arm cylinders 42 respectively connected to the pair of crank arms 41 in a driving manner, a heating wire 43 fixedly disposed at front portions of the pair of crank arms 41, and an adjustable transformer 44 electrically connected to the heating wire 43. The pair of crank arms 41 are arranged oppositely left and right, each crank arm cylinder 42 comprises a third cylinder body rotatably mounted on the moving base 12 and a third cylinder shaft which can extend and retract relative to the third cylinder body, and one end part of each third cylinder shaft, which is far away from the corresponding third cylinder body, is rotatably connected to the crank arm 41 on the corresponding side, so that the crank arm cylinder 42 can drive the corresponding crank arm 41 to rotate.

The power source 10, the adjustable transformer 44 and the heating wire 43 are electrically connected in sequence. The adjustable transformer 44 is connected to the controller 6 by signals, and the controller 6 can control the amount of current entering the heating wires 43, i.e. the heating power of the heating wires 43, via the adjustable transformer 44 to adapt to different thickness or types of prepreg tapes.

The heating wire 43 extends in the left-right direction and is fixedly provided at the front portions of the pair of crank arms 41. A pair of crank arms 41 are configured to selectively bring the heating wire 43 into and out of contact with the prepreg tape on the take-up path to selectively scald the prepreg tape. Further, the scalding mechanism further includes a pressing roller 45 rotatably disposed at a front portion of the pair and adjacent to the heating wire 43, the pressing roller 45 being configured to press down the prepreg tape on the moving path by the pair of crank arms 41 and to form a certain wrap angle with the prepreg tape so that the heating wire 43 contacts the prepreg tape.

In the automatic winding device 100 of this embodiment, after the winding roller 52 on the front side is fully wound, the winding rollers 52 on the front and rear sides can be switched by the rotating arm 51, and the power supply 10 supplies current to the heating wire 43 through the adjustable transformer 44 to rapidly heat the heating wire 43. Then, the pair of crank arms 41 is used to drive the lower pressing roller 45 to contact the heating wire 43 to the prepreg tape on the winding path. The heating wire 43 after heating can scald the presoaked belt integrally after contacting the presoaked belt, because the heating wire 43 can not pull the longitudinal spacing on the presoaked belt, so can overcome the problem that the presoaked belt is torn or the edge cutting is irregular because the fly cutter or the hot cutter pulls the fiber in the traditional winding process. During the roll change and the scalding, the stock roll 23 is raised to temporarily store a portion of the prepreg tape.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are given by way of illustration only, and that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims, specification and equivalents thereof.
