Description

Technical Field

[0001] This utility model relates to a material spreading device, and more particularly to a material spreading device for heat insulation board processing. Background Technology

[0002] During the processing of insulation boards, layers of cotton fiber fabric are stacked and then heat-pressed to form the boards. As the cotton fibers are stacked, a conveyor belt moves back and forth along guide rails. Because the conveyor belt travel varies depending on the size of the boards, typical conveyor belt control uses a program to set the duration of the motor's forward and reverse rotation. However, single layers of cotton fibers are relatively thin, and during the stacking process, the low friction between the fibers and the conveyor belt causes the fabric to flutter and slip, resulting in uneven edges. This necessitates cutting off a significant amount of the edges to make them smooth, leading to substantial material waste and increased production costs. Summary of the Invention

[0003] To overcome the above-mentioned shortcomings, this utility model provides a material spreading device that can flexibly control the conveyor belt to form back and forth, reduce the length difference of the stacked fabric edges, and reduce the loss of raw materials.

[0004] To achieve this objective, the structure adopted by this utility model is as follows: a material spreading device, including a frame, a conveyor belt, and a stacking platform. Both the conveyor belt and the stacking platform are conveyor belt structures. The stacking platform is located below the frame, and the conveyor belt is located above the stacking platform. A guide rail is provided on the frame, and the conveyor belt is connected to the guide rail through a drive structure. The conveyor belt and the stacking platform are perpendicular to each other. Multiple signal detectors are provided above one end of the stacking platform, and the signal detectors are connected to the frame.

[0005] The rack is equipped with at least four signal detectors.

[0006] A connecting strip is provided on the top of the frame. The signal detector includes a detection head, a connecting block, and a locking device. The detection head is set on the connecting block, the connecting block clamps the connecting strip, and the locking device connects the connecting block and the connecting strip to each other.

[0007] The connecting strip is a rack and pinion, and a micro motor is installed inside the connecting block. The micro motor is connected to a gear, which meshes with the rack and pinion. A locking device is connected to one side of the connecting block. The connecting block has a through hole, and the locking device has a micro motor and a pin. The pin passes through the through hole, and the micro motor controls the pin to move in and out of the through hole.

[0008] Its beneficial effects are: the structure of this utility model is reasonably and ingeniously designed. The signal detectors are respectively set at the beginning and end of the predetermined stroke, as well as on the outside of the beginning and end. When the signal detectors at the beginning and end detect the signal, they control the forward and reverse rotation of the motor connected to the conveyor belt. The signal detectors on the outside of the beginning and end detect whether the fabric exceeds the range, so as to control the rotation speed of the motor connected to the conveyor belt and pull back the excess part through speed control, so as to make the edge of the fabric stack more flat, reduce the loss of raw materials, and reduce production costs.

[0015] like Figure 1The material spreading device includes a frame 1, a conveyor belt 3, and a stacking platform 4. Both the conveyor belt 3 and the stacking platform 4 are conveyor belt structures, each equipped with a conveyor belt and a drive unit, which drives the belt to rotate. The stacking platform 4 is located below the frame 1, and the conveyor belt 3 is located above the stacking platform 4. A guide rail 2 is installed on the frame 1, and the conveyor belt 3 is connected to the guide rail 2 via a drive structure, allowing the conveyor belt 3 to move back and forth along the guide rail 2. The conveyor belt 3 and the stacking platform 4 are perpendicular to each other. Multiple signal detectors 6 are installed above one end of the stacking platform 4, and the signal detectors 6 are connected to the frame 1.

[0016] At least four signal detectors 6 are installed on the frame 1, connected sequentially. The two middle detectors 6 face the conveyor belt 3 and detect the beginning and end of the conveyor belt 3's travel. Upon detecting a signal, they transmit it to the control device, which controls the forward and reverse rotation of the conveyor belt 3's drive structure, causing the conveyor belt 3 to move back and forth within that range. The two outer detectors 6 face the edge of the stacking platform 4 and detect whether the edge width of the stacked fabric on the stacking platform 4 exceeds the limit. They transmit the signal to the controller, which controls the rotational speed of the transmission group control belt on the conveyor belt 3, reducing the width difference of the stacked fabric.

[0017] like Figure 2 As shown, a connecting strip 5 is provided on the top of the frame 1. The signal detector 6 includes a detection head 61, a connecting block 62 and a locking device 63. The detection head 61 is set on the connecting block 62, the connecting block 62 clamps the connecting strip 5, and the locking device 63 connects the connecting block 62 and the connecting strip 5 to each other. In this way, the position of the signal detector 6 can be adjusted as needed.

[0018] The connecting strip 5 is a rack, and a micro motor is installed inside the connecting block 62. The micro motor is connected to a gear, which meshes with the rack. Driven by the micro motor, the connecting block 62 moves along the rack, realizing the automatic movement of the signal detector 6. The locking device 63 is connected to one side of the connecting block 62. The connecting block 62 has a through hole, and the locking device 63 has a micro motor and a pin. The pin passes through the through hole, and the micro motor controls the pin to move in and out of the through hole, realizing the automatic locking of the locking device 63.
