Description

TECHNICAL FIELD

[0001] The present application relates to a gilding machine honeycomb plate locking device, in particular to a gilding machine honeycomb plate locking device used in the working process of large format gilding machine. BACKGROUND

[0002] In the working process of the gilding machine, the metal powder on the surface of the anodized aluminum foil needs to be pressed onto the surface of the printed matter through the gilding template to present colorful colors and wonderful patterns on the surface of the printed matter, which not only plays a decorative role but also has an anti-counterfeiting effect. The gilding template is fixed on the honeycomb plate. The honeycomb plate is fixed on the lower end surface of the fixed platform of the gilding machine. With the continuous improvement of the automation and humanization of mechanical products, the traditional manual locking of the honeycomb plate is no longer sufficient to meet the requirements. With the continuous increase of the format of the gilding machine, the honeycomb plate becomes larger and larger, and the weight increases continuously. It is more and more difficult to lock the plate manually, and faults occur frequently. SUMMARY

[0003] The present application is aimed at the defects of the existing gilding machine honeycomb plate locking device, such as complex structure, poor coordination, and low automation, and provides a honeycomb plate locking device with simple structure, pneumatic locking plate, and large format gilding requirements.

[0004] The technical scheme adopted to achieve the above-mentioned purpose is as follows: a large format gilding machine honeycomb plate locking device, including a honeycomb plate locking device on both sides and an upper locking device, a bidirectional motion air cylinder driving chain and sprocket transmission device is arranged on the transmission side of the gilding machine to realize locking of the opposite side of the honeycomb plate; a single motion air cylinder is installed on the upper part of the fixed platform of the gilding machine to serve as the upper lifting mechanism of the honeycomb plate locking device.

[0005] Compared with the prior art, the present application has the following advantages: in the working process of the gilding machine, the pneumatic locking plate is realized, which reduces the failure rate compared with the current manual locking method, is safer, greatly improves the production efficiency, and reduces the scrap rate.

[0006] Further, the optimization scheme of the present application is as follows:

[0007] The side and upper surfaces of the honeycomb plate are locked together to realize long-time work and high-temperature working conditions in the large format gilding process, so that the stress of the honeycomb plate is balanced, there is no deformation, and the large format honeycomb plate does not have the phenomenon of intermediate drop.

DETAILED DESCRIPTION

[0011] The application will be further described below in connection with the drawings and examples.

[0012] Referring to the drawings Figure 1 The chain and sprocket transmission device driven by the bidirectional motion cylinder 2 is arranged on the transmission side of the gilding machine, and is a locking mechanism for both sides of the honeycomb plate. The locking mechanism includes the chain wheel 1, the bidirectional motion cylinder 2, the support frame 3, the support shaft 5, and the side locking plate hook 6, which are respectively installed on the transmission face wall plate and the operation face wall plate of the machine frame. When the bidirectional motion cylinder 2 is started, power is transmitted to the support shaft 5 through the chain wheel 1 and the chain, and the side locking plate hooks 6 on both sides are started to act on the side locking plate.

[0013] Referring to the drawings Figure 2 The unidirectional motion cylinder 14 is installed on the upper part of the fixed platform of the gilding machine, and is an upper lifting mechanism of the honeycomb plate locking device. When the control center sends a command, the unidirectional motion cylinder 14 extends downward, and through the shaft coupling 13, the spline shaft 15, and the connecting sleeve 16, drives the oval locking plate 17 to enter the oval locking hole of the honeycomb plate, triggering the second stroke switch 141. When the control center sends a command, the bidirectional motion cylinder 2 is started to extend outward, and power is transmitted to the first transmission shaft 41 and the first bevel gear 10 through the chain wheel 1, so as to drive the second bevel gear 11 to rotate. The spline shaft 15 transmits the rotary motion to the connecting sleeve 16 and the locking plate 17, and the locking plate 17 rotates by 90° to realize the locking plate action. The unidirectional motion cylinder 14 moves to trigger the first stroke switch 21, and the unidirectional motion cylinder 14 stops moving. When the control center sends a command, the unidirectional motion cylinder 14 retracts upward, and through the shaft coupling 13, the spline shaft 15, and the connecting sleeve 16, drives the locking plate 17 to lock the honeycomb plate 18 upward.

[0014] The opposite of the honeycomb plate unlocking action program is completed. The control center issues an instruction, and the one-way motion cylinder 14 extends downward, through the shaft coupling 13, the spline shaft 15, and the connecting sleeve 16, to drive the oval locking plate 17 downward to separate from the honeycomb plate 18, unlock and relax, trigger the second travel switch 141, and the control center issues an instruction to start the contraction of the two-way motion cylinder 2. The power is transmitted to the first transmission shaft 41 and the first bevel gear 10 through the sprocket 1, thereby rotating the second bevel gear 11, and the spline shaft 15 transmits the rotary motion to the connecting sleeve 16 and the locking plate 17. The locking plate 17 rotates in the opposite direction by 90° and is consistent with the direction of the oval hole of the honeycomb plate, and at the same time, the side locking hooks 6 on both sides start the side unlocking action. When the two-way motion cylinder 2 moves and triggers the first travel switch 21, the control center issues an instruction to retract the one-way motion cylinder 14, which drives the oval locking plate 17 to separate from the honeycomb plate 18.

[0015] The above description is only the preferred embodiment of the present application, and does not limit the scope of the present application. Any equivalent structural changes made in accordance with the content of the present application and the drawings are included in the scope of the present application.
