technical field

The invention relates to a device for splicing boards.

Background technique

The production of plywood or plywood is to cut the wood raw materials into boards and then splice and lengthen the boards, then cut them according to the specifications and glue the multi-layer boards to form them. The cutting of the plates in the above process has relatively mature automation equipment, but there are many and relatively complicated process steps in the splicing of the plates, including the chamfering of the splicing edges of the plates, the gluing between the edges of the plates, etc. Among them, the splicing and lengthening process requires the edges of adjacent plates to be spliced to each other by gluing, and then the spliced plates are transported to the shearing machine for cutting according to specifications. Although the splicing of the boards has been glued, due to the relatively low initial strength of the bonding, degumming or misalignment is prone to occur during the transportation process, which affects the quality of the splicing.

detailed description

Referring to Fig. 1 to Fig. 2, the plate infinite lengthening mechanism includes a pressure splicing mechanism and a plate conveying mechanism, wherein the pressure splicing mechanism is composed of a pressure gate 1 and a driving mechanism of the pressure gate 1, and the driving mechanism drives the pressure gate 1 to the splicing of the plates Apply pressure to join; the plate conveying mechanism is composed of a sheet clamp 2 that can be opened and closed and a driving mechanism for opening and closing. The plate conveying mechanism is installed on the slide rail 3, and is driven by the translation mechanism to move in translation between the pressure gate 1 and the plate outlet. between. The plates after chamfering and cutting are sent to the equipment in turn, and the edges of the adjacent plates are glued under the pressure of the pressure gate 1 through the pressure splicing mechanism to ensure the flatness and connection strength of the joint. After the pressure splicing, the plates are clamped 2 Translate to the splicing place and clamp the splicing part, and then move in translation, which can ensure that the splicing part is less stressed during the conveying process of the board, thereby preventing the splicing part from being disengaged or dislocated. This equipment can automatically complete pressure splicing, conveying and cutting processes, with a high degree of automation, which can effectively improve production efficiency and ensure the splicing quality of the plates.

Conveyor belts can generally be used to transport plates, but considering that plates will bend and wrinkle, it is not conducive to use conveyor belts, and it is easy to cause disengagement or misalignment of the splicing parts. Therefore, the splicing parts need to be fixed during transmission. The solution adopted by the present invention It is implemented by means of clips, including a sheet clamp 2 composed of a pair of clip arms that open and close. The clip arms of the sheet clip 2 are opened so that the sheet clip 2 can move and enter the position of the pressure splicing mechanism, and then the sheet clip 2. When it is closed, it can clamp the splicing part of the board, and then move the board through translation until the edge of the board to be spliced moves into the pressure splicing mechanism. Wherein the clip arm is rotatably installed on the bracket through the rotating shaft 4, and the rotating shaft 4 is fixed with a gear 5; Also fixed on the rotating arm 6, the end of the rotating arm 6 is connected to the telescopic drive mechanism 7 that drives the rotating arm 6 to move up and down, wherein the telescopic mechanism can be an air cylinder or a hydraulic cylinder, etc., and the telescopic mechanism drives the rotating arm 6 to move up and down and simultaneously drives the corresponding rotation. The rotating shaft 4 where the arm 6 is located rotates, and the other rotating shaft 4 is driven to rotate synchronously through the meshing gear 5 transmission. As the two rotating shafts 4 rotate, the two clamp arms also correspondingly open or close.

In order to clamp and fix the splicing parts of the plates, the number of the plate clamps 2 is 4 groups, 2 groups are distributed along the two sides of the plates, and the 2 sets of plate clamps 2 on the same side are distributed front and back and installed on a bracket. The arms are connected to the same shaft 4 . In this way, the four groups of plate clamps 2 can clamp the front and rear of the spliced parts of the plates, realize the fixing of the spliced parts, and effectively prevent the spliced parts from being disengaged or dislocated.

The pressure gate 1 is composed of upper and lower pressing plates, which are respectively connected with upper and lower pneumatic cylinders. The cylinder rod of the pneumatic cylinder drives the movement of the upper and lower pressure plates to realize the opening and closing of the pressure gate 1 .

In order to keep the plate clamps 2 on both sides to translate synchronously, the supports on both sides of the plate pass through the synchronous connecting rod 8, and the top and bottom of the support are respectively equipped with rollers 9, which cooperate with the upper and lower rails 3 respectively.

Due to the large length of the plates after splicing, the bottom of the plates needs to be supported during translation. For this reason, a supporting plate 10 for supporting the plates is also laid between the pressure gate 1 and the plate outlet. The width of the supporting plate 10 is greater than Or equal to the width of the sheet material, the sheet material moves on the clamping lower pallet 10 of the sheet material folder 2 . In order to facilitate the opening of the lower clamp arm of the plate clamp 2, the support plate 10 is provided with a hollow position 11 through which the clamp arm passes.

In order to make the equipment automatically cut the board according to the needs of use or production standards, there is also a cut-to-length shear 12 for cutting the board at the board outlet. .
