Servo synchronous film release mechanism

Abstract

The present invention provides a servo synchronous film-release mechanism, including a conveyor belt for conveying a plate to a next workstation; a push block, which is arranged on the conveyor belt and moves with the conveyor belt, and is used to move the plate; a silo, which is located above the conveyor belt; a height-limiting plate, which is arranged at the discharge port of the silo; and a negative pressure chamber, which is located below the conveyor belt. When the conveyor belt drives the push block to move to the silo, the negative pressure chamber negatively adsorbs the end of the plate. The working principle of the present invention is as follows: when the plate needs to be processed, the stacked plates are first placed in the silo, and the height of the height-limiting plate is adjusted to allow only the bottom plate to pass through; when the push block runs to the silo, the negative pressure chamber adsorbs the end of the plate, and pulls the two ends of the plate downward to make the plate flat front and back, and the push plate can easily push out the bottom plate, which solves the problem of traditional film-release mechanisms affecting production efficiency due to the warping of the two ends of the plate.

Description

Technical Field

[0001] The invention relates to the technical field of woodworking machinery, in particular to a servo synchronous chip-spinning mechanism. Background Art

[0002] In woodworking enterprises, in order to save space, raw materials are generally placed in a stacked manner. When the materials need to be processed, the stacked materials are placed together in the work area and automatically processed through an assembly line. A push block is provided on the sheet-launching mechanism of the assembly line to push the bottom sheet out for processing. However, the raw materials are generally warped at both ends, and the push block often passes through the bottom of the sheet because it cannot reach the end of the sheet, thereby affecting production efficiency. Summary of the invention

[0003] The technical problem to be solved by the present invention is to solve the technical problem that the efficiency of the plate pusher is affected by the warping of the two ends of the plate in the traditional plate-sending mechanism.

[0004] The present invention provides a servo synchronous film-launching mechanism.

[0005] It includes a conveyor belt for conveying the sheet to the next station;

[0006] A push block, which is arranged on the conveyor belt and moves along with the conveyor belt, and is used to push the plate;

[0007] A silo, located above the conveyor belt;

[0008] A height limiting plate is arranged at the discharge port of the silo;

[0009] It also includes a negative pressure chamber, which is located below the conveyor belt. When the conveyor belt drives the push block to move to the silo, the negative pressure chamber absorbs the end of the plate with negative pressure.

[0010] The working principle of the present invention is as follows: when the plates need to be processed, the stacked plates are first placed in the silo, and the height of the height limit plate is adjusted to allow only the bottom plate to pass through; when the push block runs to the silo, the negative pressure chamber adsorbs the end of the plate and pulls both ends of the plate downward to make the plate flat front and back, and the push plate can easily push out the bottom plate, solving the problem of the traditional plate-issuing mechanism affecting production efficiency due to the warping of both ends of the plate.

[0011] Furthermore, the conveyor belt is provided with a first through hole, which is located in front of the push block and is connected to the negative pressure chamber. The front and rear ends of the plate cover the first through hole; when the plate runs to the height limit plate, the first through hole is connected to the negative pressure chamber, and the negative pressure in the negative pressure chamber adsorbs and pulls the two ends of the plate downward, making the plate flat front and back; the first through hole is set as a waist hole in the direction of the conveyor belt, which is used to increase the area of ​​the first through hole and increase the force-bearing area at both ends of the plate.

[0012] Furthermore, the negative pressure chamber is arranged below the silo, and when the first through hole follows the conveyor belt to move to the negative pressure chamber, a connection is formed, so that the negative pressure adsorbs the end of the plate. Since only the negative pressure chamber below the silo plays an effective role, such a design reduces the length of the negative pressure chamber and improves the utilization rate of the negative pressure chamber.

[0013] Furthermore, a plurality of second through holes are provided on the upper part of the negative pressure chamber, and when the end of the plate is adsorbed by negative pressure, the plurality of second through holes are connected with the first through hole.

[0014] Furthermore, the height limit board is provided with a driving mechanism for driving the height limit board to change in the height direction. In case of an error, two plates will pass under the height limit board at once. When the plates and the height limit board are stuck, the problem of the stuck can be solved by starting the driving mechanism and raising the height limit board. The operation is simple and convenient.

[0015] Furthermore, the driving mechanism includes a cylinder and an inclined linear guide rail. The height limit plate is installed on the slider of the linear guide rail. When the plate hits the height limit plate, due to the small power output of the cylinder, the height limit plate will drive the cylinder piston rod to retract one end distance, playing a buffering role, thereby protecting the plate from being hit.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0025] like Figure 1 As shown, the present invention is a servo synchronous sheet-feeding mechanism, comprising two sets of conveyor belts 1 arranged symmetrically, used to convey the sheet to the next station, and the conveyor belts 1 are driven by a servo motor and a planetary reducer to ensure that the two conveyor belts 1 run synchronously; Figure 2 As shown, a push block 2 is provided on the conveyor belt 1 for moving the plate; the conveyor belt 1 is provided with a first through hole 11, which is located in front of the push block 2, and the first through hole 11 is a waist hole; Figure 6 As shown, a silo 3 is provided above the conveyor belt 1;

[0026] like Figure 3 As shown, the discharge port of the silo 3 is provided with a height limiting plate 4, and the height limiting plate 4 is provided with a driving mechanism 6 for driving the height limiting plate 4 to change in the height direction; the driving mechanism 6 includes a cylinder 61 and an inclined linear guide 62, and the height limiting plate 4 is installed on a slider of the linear guide 62. When the plate hits the height limiting plate 4, due to the small power output by the cylinder 61, the height limiting plate 4 will drive the piston rod of the cylinder 61 to retract one end distance, which plays a buffering role, thereby protecting the plate from being hit; when an error occurs, two plates will pass under the height limiting plate 4 at once. When the plate and the height limiting plate 4 are stuck, it is only necessary to start the cylinder 61 and raise the height limiting plate 4 to solve the problem of being stuck. The operation is simple and convenient;

[0027] like Figure 4 and Figure 5 As shown, a negative pressure chamber 5 is provided below the silo 3, and a plurality of second through holes 51 are provided at the upper end of the negative pressure chamber 5. When the conveyor belt 1 drives the push block 2 to move to the silo 3, the first through hole 11 and the second through hole 51 are connected, and the negative pressure chamber 5 negatively absorbs the end of the plate;

[0028] The working principle of the present invention is as follows: when the plates need to be processed, the stacked plates are first placed in the silo 3, and the height of the height-limiting plate 4 is adjusted to allow only the bottom plate to pass through; when the push block 2 runs to the silo 3, the negative pressure chamber 5 adsorbs the end of the plate and pulls both ends of the plate downward to make the plate flat front and back, and the push plate can easily push out the bottom plate, solving the problem of the traditional plate-issuing mechanism affecting production efficiency due to the warping of both ends of the plate.
