In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a detailed description of various exemplary embodiments or modes of practice of the invention. However, various exemplary embodiments may be practiced without these specific details or with one or more equivalent arrangements. Moreover, the various exemplary embodiments may be different, but are not necessarily exclusive. For example, the particular shapes, configurations and characteristics of the exemplary embodiments may be used or implemented in another exemplary embodiment without departing from the inventive concept.

Further, in this application, spatially relative terms such as "below … …", "below … …", "below … …", "below", "above … …", "above … …", "higher", "side" (e.g., as in "sidewall"), etc., thus describe the relationship of one element to another (other) element as shown in the figures. Spatially relative terms are intended to encompass different orientations of the device in use, operation, and/or manufacture in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" or "beneath" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "below … …" may include both an orientation of above and below. Further, the devices may be otherwise positioned (e.g., rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

In this application, the term "upstream" or "downstream" means that a component is located upstream or downstream of another component with respect to the feed path. For example: by "spreader roll is located upstream of the drive roll", it is meant that the spreader roll is located upstream of the drive roll with respect to the feed path.

Fig. 1 shows the compounding device 100 for prepreg tapes provided by the present invention, wherein the compounding device 100 comprises a first frame 1 supported on the ground or a pedestal, a first unreeling seat 21 and a second unreeling seat 22 installed on the first frame 1, a material placing rack 3 fixedly installed on the upper side of the first frame 1, and a compounding machine 4 for laminating a bottom prepreg tape 10 and a reinforcement prepreg tape 20.

The first chassis 1 is made of a rigid material. The first unwinding seat 21 and the second unwinding seat 22 are disposed at one side end of the first frame 1, and are each configured to accommodate a roll for providing the base prepreg tape 10. The first and second unwinding stations are standby for each other to continuously supply the bottom prepreg tape 10.

The placement frame 3 has a flat top surface and is configured to place a sheet-like reinforcement layer prepreg tape 20. The assembly 100 defines a supply path (not shown) for movement of the underlying prepreg tape 10. The first frame 1 defines a discharge area 11 adjacent to the loading frame 3, the discharge area 11 being located on the feeding path and configured to allow the operator to place the reinforcing layer prepreg tape 20 on the base prepreg tape 10.

Further, the compound device 100 further comprises a pre-tightening seat 5 located between the material placing frame 3 and the first and second unwinding seats. The pre-tightening seat 5 is fixedly mounted on the first frame 1 and is located on the feeding path. The pre-tensioning base 5 is provided with a pair of rotatable pre-tensioning rollers 51, and the pair of pre-tensioning rollers 51 can respectively abut against the upper and lower surfaces of the bottom prepreg tape 10 and tension the bottom prepreg tape 10 to maintain the surface tension of the bottom prepreg tape 10.

Referring to fig. 2-3, the compound machine 4 includes a second frame 41 supported on the ground or a pedestal, a driving roller 42 rotatably mounted on the second frame 41, a driving motor 43 in driving connection with the driving roller 42, a pressing roller 44 located on the upper side of the driving roller 42, and a plurality of pressing seats 45 disposed at the driving roller 42.

The second frame 41 is made of a rigid material and is mechanically coupled to the end of the first frame 1 at a side away from the first and second unwinding seats. The feed path passes between the main drive roller 42 and the stitching roller 44. The drive roll 42 extends in the left-right direction, and the compound machine 4 is further arranged with a heating duct 46 penetrating the inside of the drive roll 42 and through which a heating fluid can flow to heat the outer peripheral surface of the drive roll 42. The driving motor 43 is fixedly installed on the second frame 41 and located at the lower side of the driving roller 42, and is used for driving the driving roller 42 to rotate. Further, the driving motor 43 is a servo motor to precisely adjust the rotation speed of the driving roller 42.

The complex machine 4 is provided with a pair of right and left laminating cylinders 47. Each of the pressing cylinders 47 includes a cylinder body (not shown) fixedly mounted on the second frame 41 and a cylinder shaft which is extendable and retractable with respect to the cylinder body. The nip roller 44 extends in the left-right direction, and both side end portions of the nip roller 44 are respectively rotatably supported on a pair of cylinder shafts, so that a pair of nip cylinders 47 can drive the nip roller 44 to move up and down.

Each of the pressing bases 45 is located downstream of the pressing roller 44 and includes a base (not shown) fixedly mounted on the second frame 41, a rotatable pressing roller 451, and a pressing cylinder 452 for driving the pressing roller 451 to move toward the driving roller 42. The feed path passes between the pinch rollers 451 and the drive roller 42, each pinch roller 451 being configured to contact the drive roller 42 or a composite prepreg tape positioned on the drive roller 42 (see below) under the influence of a pinch cylinder 452.

Further, a spreader roll 48 is disposed upstream of the drive roll 42 on the compound machine 4. The spreader roll 48 is rotatably mounted on the second frame 41 and is configured to be able to contact the reinforcing-layer prepreg tape 20 to flatten the reinforcing-layer prepreg tape 20 on the base prepreg tape 10.

The working principle of the compound device 100 is explained below: the bottom prepreg tape 10 is fed from the first unwinding seat 21 or the second unwinding seat 22, and then passes through the pre-tightening seat 5 and the material placing rack 3 to reach the material placing area 11. The worker places the reinforcing-layer prepreg tapes 20 on the placement frame 3 one by one on the base-layer prepreg tape 10. The reinforcing prepreg tape 20 is flattened by the spreader roll 48 and then reaches the drive roll 42 and the nip roll 44 together with the lower prepreg tape 10. The driving roller 42 and the pressing roller 44 heat the bottom layer prepreg tape 10 and the reinforcing layer prepreg tape 20 and press the two into a composite prepreg tape. Thereafter, the composite prepreg tape is kept in a state of being attached to the drive roll 42 and is continuously heated by the plurality of press rolls 451, so that the composite effect of the base prepreg tape 10 and the reinforcing-layer prepreg tape 20 is ensured. Compared with a traditional tablet press, the composite device 100 can continuously produce the composite prepreg tape and has higher production efficiency.
