The feed roller 31 of the present invention is unpowered, and as the tape roll is pulled during the laying operation, the feed roller 31 rotates to release the tape.

[0032] Optionally, the feed roller 31 of the present invention has a driving force, which can match the laying operation speed of the material strip to control the rotation speed of the feed roller 31 so that the release speed of the material strip is compatible with the laying operation of the material strip. Those skilled in the art can use a stepper motor or a variable frequency motor to connect the feed roller 31 to control its rotation speed.

[0033] The reel assembly has the same number of reel rollers 41 as the tape laying heads 2, and each reel roller 41 is provided corresponding to a tape laying head 2;

[0034] Combination Figure 6 The material strip of the present invention comprises a material layer 200 and a backing paper 100. The material strip is rolled up to form a material strip roll, and the backing paper 100 separates two adjacent material layers 200 to avoid adhesion.

[0035] The winding roller 41 is configured to: during the laying operation of the tape laying head 2, in real time wind up the backing paper 100 separated from the material layer 200 to achieve the recovery of the backing paper 100. The winding roller 41 of the present invention has a driving force, and the speed of the winding roller 41 is controlled to be compatible with the laying operation of the material tape.

[0036] Optionally, those skilled in the art may control the rotation speed of the winding roller 41 to put the backing paper 100 in an appropriate tensioned state, apply a certain pulling force to the material belt, and prevent the material belt from becoming loose during the feeding process.

[0037] A longitudinal moving platform 5 is arranged below the tape laying head 2; the longitudinal moving platform 5 can make reciprocating linear movements in a horizontal plane, and its moving direction is perpendicular to the moving direction of the tape laying head 2; a core mold 51 is arranged on the longitudinal moving platform 5;

[0038] The tape laying head 2 presses the material layer 200 of the material tape onto the core mold 51; the present invention is provided with multiple tape laying heads 2, which can press and lay multiple strips of material tape at the same time, thus greatly improving the operation efficiency.

[0039] Optionally, the number of the tape laying heads 2 of the present invention is three, four or five.

[0040] As an embodiment, the plurality of tape laying heads 2 of the present invention are arranged at equal intervals, and the distance between two adjacent tape laying heads 2 is an integer multiple of the width of the laid material tape;

[0041] During the tape laying operation, each tape laying head 2 simultaneously lays multiple layers of material 200 on the core mold 51, and then the longitudinal moving table 5 moves a distance equal to the width of the material tape. Each tape laying head 2 lays the second layer again, and then operates in sequence until the laying is completed. Compared with the single-strip tape laying equipment, the operating efficiency of the present invention is improved several times, and the tape laying operation of a large area can be completed quickly.

[0042] As an embodiment, two longitudinal rails 52 are provided below the bunk bed frame 1, and the longitudinal platform 5 is slidably arranged on the longitudinal rails 52, so that the longitudinal platform 5 moves in an accurate direction and has a stable posture during the movement. The longitudinal platform 5 of the present invention can be provided with a hydraulic cylinder or an electric cylinder between the two longitudinal rails 52 to accurately control the moving distance of the longitudinal platform 5.

[0043] As an embodiment, the core mold 51 is rotatably arranged on the longitudinal moving platform 5; after the previous laying operation is completed, the rotation angle of the core mold 51 can be controlled to carry out the next laying, so that cross-laying of different laying layers 200 can be achieved.

[0044] Those skilled in the art can realize the rotational installation of the core mold 51 on the longitudinal moving platform 5 through a known structure. For example, a slewing bearing is provided between the core mold 51 and the longitudinal moving platform 5 to realize the rotation of the core mold 51. A rotating motor is installed on the longitudinal moving platform 5 to control the rotation angle of the core mold 51.

The cutting knife 34 of the present invention is preferably an ultrasonic knife with high cutting accuracy.

[0046] Optionally, the tape laying head 2 moves from the side of the winding wheel group to the side of the feeding wheel group to complete the laying of a layer of material 200. Those skilled in the art can pre-calculate the laying length of each layer of material 200 according to the specifications of the core mold 51, and start the cutter 34 to cut the layer of material 200 when the material tape reaches a predetermined length.

[0047] After the paving layer 200 is laid, the tape laying head 2 moves horizontally to the side of the winding wheel group to prepare for the next paving operation. During the movement of the tape laying head 2, the winding roller 41 rotates synchronously to roll up the backing paper 100, and the feeding roller 31 rotates synchronously to release the material tape.

[0048] This embodiment realizes automatic cutting of the material layer 200 by providing a horizontally movable cutter 34, thereby further improving the automation level of the tape laying operation.

[0049] As an embodiment, a feeding frame 3 and a receiving frame 4 are respectively provided at both ends of the bunk frame 1; the feeding wheel set is installed on the feeding frame 3, and the receiving wheel set is installed on the receiving frame 4;

[0050] See also Figure 3 Furthermore, a discharge hole 36 is provided on the feed rack 3; a heating lamp 33 is provided next to the discharge hole 36 and is located below the head rack 1. After the material strip is led out from the feed roller 31, its paving layer 200 faces outward, and after being led out from the discharge hole 36, the paving layer 200 faces downward. The heating lamp 33 heats the paving layer 200 during the laying process of the material strip, so that it can be better bonded or formed. Especially when laying materials that require heat treatment, such as heat-sensitive materials, the heating lamp 33 can first heat them to a preset temperature to improve the molding quality.

[0051] Preferably, the heating lamp 33 of the present invention is an infrared heating lamp.

[0052] Better yet, a feeding hole is provided on the bunk bed frame 1, and a guide roller 13 for placing the material belt is provided in the feeding hole; so that the material belt can maintain a certain tension during the conveying process to avoid falling.

[0053] Optionally, the feeding rack 3 is further provided with a reversing roller 35 for guiding the feeding belt at the corner position to reduce the resistance encountered by the feeding belt at the corner position.

[0054] See also Figure 4 As an embodiment, the head frame 1 is also provided with a return port 12, and the backing paper 100 is guided to the top of the head frame 1 from the return port 12. At the end of the winding process, the backing paper 100 moves on the top surface of the head frame 1, and is not easy to deviate during the winding process.

[0055] Furthermore, a guide plate 16 is obliquely provided in the return port 12 to reduce the resistance of the backing paper 100 at the corner of the return port 12 .

[0056] See also Figure 4 As an embodiment, the same number of transverse rails 11 as the tape laying heads 2 are horizontally arranged below the said tape laying frame 1; a transverse sliding block 14 is slidably arranged on the said transverse sliding rail 11, and the said transverse sliding block 14 is hoisted to the said tape laying heads 2;

[0057] Optionally, the transverse sliding block 14 is threadedly connected to a lead screw, and the lead screw is drivingly connected to a transverse moving motor 15; the transverse moving motor 15 is preferably a stepping motor or a variable frequency motor, which accurately controls the movement of the tape laying head 2.

[0058] See also Figure 5 As an embodiment, the tape laying head 2 includes a support block 21 , and a pressure roller 2 is provided on the support block 21 ; it is used to press the material layer 200 of the material tape onto the core mold 51 .

[0059] Furthermore, a pressure shoe 25 is provided on the support block 21; two inclined guide grooves 211 are provided on the support block 21; the pressure roller 2 and the pressure shoe 25 are respectively slidably disposed in the guide grooves 211 on the corresponding side;

[0060] The pressure roller 2 and the pressure shoe 25 can move along their respective guide grooves 211 to change height, thereby changing pressure or breaking contact with the material strip. The pressure roller 2 and the pressure shoe 25 of the present invention can alternately complete the pressing action and switch to meet different material strip compaction requirements.

[0061] As a preferred solution, a guide shaft 22 with a rectangular cross-section is slidably disposed in the guide groove 211, and the guide shaft 22 is transmission-connected to the adjusting electric cylinder 23; the pressure roller 2 and the pressure shoe 25 are respectively fixedly connected to the guide shaft 22 in the corresponding guide groove 211;

[0062] Optionally, a pressure roller arm 241 is fixedly provided on both sides of the pressure roller 2, and the two pressure roller arms 241 are fixedly connected to the corresponding guide shaft 22; a pressure shoe arm 251 is fixedly provided on both sides of the pressure shoe 25, and the two pressure shoe arms 251 are fixedly connected to the corresponding guide shaft 22.

[0063] The cross-sectional shape of the guide shaft 22 is rectangular, and its two opposite surfaces respectively fit on the side walls of the guide groove 211, limiting the rotation of the guide shaft 22 so that when the guide shaft 22 slides in the guide groove 211, the verticality of the pressure roller 2 and the pressure shoe 25 can be maintained to ensure the compaction quality.

[0064] See also Figure 6 During the pressing operation, after the backing paper 100 of the material strip is separated from the material layer 200, it passes through the gap between the pressing roller 24, the pressing shoe 25 and the support block 21 and is pulled obliquely upward. Furthermore, a material guide box 26 is fixed on the support block 21, and the backing paper 100 passes through the material guide box 26 to avoid deviation; it also prevents the backing paper 100 from contacting with the pressing roller 24 or the pressing shoe 25 when the material strip is loose, thereby interfering with the compaction operation.

[0065] In summary, the present invention provides a multi-strip synchronous laying device, which can lay multiple strips of material at the same time by setting multiple tape laying heads, greatly improving the working efficiency. Compared with the existing single-strip tape laying equipment, the working efficiency of the present invention is improved several times, and the large-area tape laying operation can be completed quickly.

[0066] Of course, the present invention may have many other embodiments.
