Description

Technical Field

[0001] The utility model relates to the technical field of PVC card production equipment, in particular to a PVC card punching machine. Background Art

[0002] PVC card refers to a card made of PVC material, which has the characteristics of light weight, heat insulation, thermal insulation, moisture resistance, flame retardancy, and easy construction. PVC material is a kind of plastic decorative material, which is the abbreviation of polyvinyl chloride material. It is made of polyvinyl chloride resin as the main raw material, adding appropriate amount of anti-aging agent, modifier, etc., and is made through mixing, calendering, vacuum forming and other processes.

[0003] The production process of PVC cards is as follows: print the image and text on a special 0.3mm thick PVC color inkjet sheet base through an ordinary color inkjet printer, and then cover the front and back sides with two 0.2mm thick special adhesive films, and use a heat-sealing plastic sealing machine to synthesize them. Finally, use a card punching machine to directly punch and cut into finished cards. Existing card punching machines mostly use intermittent feeding mechanisms. This feeding mechanism adopts a reciprocating single-track feeding form. After all feeding mechanisms on the conveyor table complete feeding, the card punching machine will have an intermittent period, and the subsequent feeding mechanism will return to continue feeding and returning. This single-track reciprocating feeding design will affect the punching production efficiency of the card punching machine. In addition, the punching slot of the card punching machine will have a jam phenomenon during the punching production, which affects the subsequent punching production. Therefore, we proposed a PVC card punching machine to solve the above problems. Utility Model Content

[0004] The utility model aims to improve the production efficiency of a card punching machine and avoid the jamming phenomenon of a card punching slot of the card punching machine, and thus provides a PVC card punching machine.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The PVC card punching machine comprises a supporting mechanism, wherein a plurality of feeding mechanisms are arranged inside the supporting mechanism, a bracket is arranged above the supporting mechanism, a cylinder is installed on the bracket, a punching mechanism is installed at the lower end of the cylinder output end, a conveyor belt is arranged below the punching mechanism, four electric telescopic rods are symmetrically installed at the bottom of the supporting mechanism, and a top plate is fixedly installed on the output end of the electric telescopic rod; the feeding mechanism comprises an electric slider, a cross plate and a placement slot, the cross plate is fixedly installed between two electric sliders, the placement slot is fixedly installed on the upper side of the cross plate, and reinforcing bars are evenly fixedly installed below the cross plate; the punching mechanism comprises a mounting plate, a punching slot and an air pump, the mounting plate is fixedly installed on the output end of the cylinder, a plurality of the punching slots are installed at the bottom of the mounting plate, the air pump is fixedly installed on the upper side of the mounting plate, a plurality of groups of punching air pipes are arranged at the positions of the mounting plate corresponding to the punching slots, the lower end of the punching air pipe passes through the inner side of the punching slot and the upper end of the punching air pipe is connected and installed with a connecting pipe, and the connecting pipe is connected with the output end of the air pump.

[0007] Preferably, a controller is installed on the side of the bracket.

[0008] Preferably, the supporting mechanism includes a support leg, a crossbeam and a rectangular rail groove, the crossbeam is fixedly installed above the support leg, the rectangular rail groove is opened on the inner side of the crossbeam, and through grooves are opened at both ends of the rectangular rail groove, and the width of the through groove is adapted to the width of the top plate.

[0009] Preferably, the electric slider is slidably installed on the inner side of the rectangular rail groove, a roller is rotatably installed on the lower side of the electric slider, and a plurality of punching openings are opened on the inner side of the placement groove, and the cross-sectional size of the punching openings is adapted to the cross-sectional size of the punching slot.

[0010] Preferably, two stable telescopic rods are symmetrically arranged on the upper side of the mounting plate, and the stable telescopic rods are fixed between the bracket and the mounting plate.

[0011] The PVC card punching machine is characterized in that the supporting mechanism and the feeding mechanism are provided, wherein the supporting mechanism is provided with a rectangular track groove, and a through groove is opened in the rectangular track groove. This design makes the track of the feeding mechanism a circulating track. During the feeding process, the feeding mechanism is driven by the electric slider to slide inside the rectangular track groove and move to the bottom of the punching mechanism to feed the material. After the feeding is completed, it continues to move to the left side of the rectangular track groove. When it moves to the left through groove, the electric telescopic rod is started to drive the top plate to move the feeding mechanism to the track on the lower side of the rectangular track groove. The subsequent electric slider is reversely transported. Under the transportation of the electric slider, when the feeding mechanism moves to the through groove on the right side of the rectangular track groove, the electric telescopic rod on the right side is started to drive the top plate to transport the feeding mechanism through the through groove to the track on the upper side of the rectangular track groove, completing self-circulating feeding and returning. The coordinated design of the supporting mechanism and the feeding mechanism makes the utility model a circulating track feeding design. The feeding and returning between the feeding mechanisms do not interfere with each other, thereby reducing the intermittent time of the PVC card punching machine and improving the production efficiency.

[0012] In the utility model, the PVC card punching machine is provided with a punching mechanism. When the feeding mechanism conveys the finished PVC composite card board to the bottom of the punching mechanism, the punching mechanism is driven downward by the cylinder to punch the finished PVC composite card board. When the punching slot in the punching mechanism moves downward to the inside of the punching slot in the feeding mechanism, the finished PVC composite card board is punched to form a plurality of cards. At this time, the air pump is started to convey high air pressure into the punching slot below through the air flushing pipe, and the punched cards are punched and dropped onto the conveyor belt below through the punching slot, so as to prevent the punched cards from being stuck inside the punching slot and affecting the subsequent punching production, thereby further improving the production efficiency of the equipment.

[0013] The utility model has a reasonable design. Through the coordinated design of the supporting mechanism and the feeding mechanism, the utility model is designed for circular track feeding. The feeding and returning between the feeding mechanisms do not interfere with each other, which reduces the intermittent time of the PVC card punching machine and improves the production efficiency. In addition, the design of the punching mechanism prevents the punched and formed cards from being stuck on the inside of the punching slot, thereby affecting the subsequent punching production, and further improves the production efficiency of the equipment.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

The groove 23 is fixedly installed on the upper side of the cross plate 22, and the reinforcing rod 24 is evenly fixedly installed below the cross plate 22; the punching mechanism 7 includes a mounting plate 71, a punching slot 72 and an air pump 75, the mounting plate 71 is fixedly installed on the output end of the cylinder 4, a plurality of punching slots 72 are installed at the bottom of the mounting plate 71, the air pump 75 is fixedly installed on the upper side of the mounting plate 71, and a plurality of groups of air punching pipes 73 are arranged on the mounting plate 71 at the positions corresponding to the punching slots 72, the lower ends of the air punching pipes 73 pass through the inner sides of the punching slots 72 and the upper ends of the air punching pipes 73 are connected with connecting pipes 74, and the connecting pipes 74 are connected to the output end of the air pump 75.

[0022] Through the above structure, the electric slider 21 is started, and the electric slider 21 drives the roller 211 to rotate to obtain the conveying power inside the rectangular track groove 13. The reinforcing bars 24 evenly arranged below the cross plate 22 improve the overall strength of the cross plate 22, reduce the deformation of the cross plate 22 during the punching process of the punching machine, and thus improve the card quality of the card; when the feeding mechanism 2 conveys the finished PVC composite cardboard to the bottom of the punching mechanism 7, the punching mechanism 7 is driven downward by the cylinder 4 to punch the finished PVC composite cardboard, and the punching slot 72 in the punching mechanism 7 moves downward to the inside of the punching slot 25 in the feeding mechanism 2, so that the finished PVC composite cardboard is punched to form a number of cards. At this time, the air pump 75 is started to convey high air pressure to the punching slot 72 below through the air flushing pipe 73, and the punched cards are punched through the punching slot 25 to the conveyor belt 8 below, so as to prevent the punched cards from being stuck inside the punching slot 72, thereby affecting the subsequent punching production, thereby improving the production efficiency.

[0023] In this embodiment, the support mechanism 1 includes a support leg 11, a cross beam 12 and a rectangular rail groove 13. The cross beam 12 is fixedly installed above the support leg 11. The rectangular rail groove 13 is opened on the inner side of the cross beam 12. The two ends of the rectangular rail groove 13 are connected to each other and a through groove 14 is opened. The width of the through groove 14 is adapted to the width of the top plate 10.

[0024] Through the above structure, the rectangular track groove 13 and the through groove 14 are opened on the inner side of the cross beam 12. The through groove 14 makes the inner rectangular track groove 13 become a circulating track. The circulating track provided for the feeding mechanism 2 avoids the interference of feeding return in the traditional reciprocating monorail design, reduces the return interval time, and improves the feeding efficiency.

[0025] In this embodiment, the electric slider 21 is slidably installed on the inner side of the rectangular rail groove 13, and a roller 211 is rotatably installed on the lower side of the electric slider 21. A plurality of punching openings 25 are opened on the inner side of the placement groove 23, and the cross-sectional size of the punching openings 25 is adapted to the cross-sectional size of the punching groove 72.

[0026] In this embodiment, two stabilizing telescopic rods 5 are symmetrically arranged on the upper side of the mounting plate 71 , and the stabilizing telescopic rods 5 are fixed between the bracket 3 and the mounting plate 71 .

[0027] Through the above structure, when the cylinder 4 drives the punching mechanism 7 to work, the symmetrically arranged stable telescopic rods 5 provide stable guiding performance for the rise or fall of the punching mechanism 7, thereby improving the stability of the device in punching production.

[0028] In the utility model, when in use, the mechanical arm on the production line places the finished PVC composite pallet into the placement slot 23 in the feeding mechanism 2, and the electric slider 21 starts to transport the finished PVC composite pallet to the bottom of the punching mechanism 7. When it is transported to the bottom of the punching mechanism 7, the electric slider 21 stops driving, and the cylinder 4 drives the finished PVC composite pallet downward to punch and cut. When the punching slot 72 in the punching mechanism 7 moves downward to the inside of the punching port 25 in the feeding mechanism 2, the finished PVC composite pallet is punched to form a number of cards. At this time, the air pump 75 starts to transport high air pressure into the punching slot 72 below through the air pipe 73, and the punched cards are punched and dropped onto the conveyor belt 8 below through the punching port 25. The conveyor belt 8 transports the punched cards to the rear end of the production line. After the punching is completed, the cylinder 4 drives the punching mechanism 7 to retract to the top to wait for the next punching. At this time, the electric slider 2 When the feeding mechanism 2 is started and driven to move to the left through slot 14, the electric telescopic rod 9 is started and drives the top plate 10 to move the feeding mechanism 2 to the lower track of the rectangular track slot 13, and the electric slider 21 is subsequently transported in the reverse direction. Under the transportation of the electric slider 21, when the feeding mechanism 2 moves to the right through slot 14 of the rectangular track slot 13, the electric telescopic rod 9 on the right is started and drives the top plate 10 to transport the feeding mechanism 2 through the through slot 14 to the upper track of the rectangular track slot 13, completing the self-circulating feeding and folding. The robot arm on the subsequent production line clamps out the finished PVC composite pallet waste inside the placement slot 23 of the returned feeding mechanism 2, and then places the new finished PVC composite pallet inside the placement slot 23, and the feeding mechanism 2 continues to circulate and feed. When it is necessary to improve the production efficiency here, it can be achieved by setting several groups of feeding mechanisms 2 inside the rectangular track slot 13, which can reduce the intermittent time of the punching mechanism 7. The above is the working process and principle of the utility model. The utility model adopts a circular track feeding design through the coordinated design of the supporting mechanism 1 and the feeding mechanism 2. The feeding and returning between the feeding mechanisms 2 do not interfere with each other, which reduces the intermittent time of the PVC card punching machine and improves the production efficiency. In addition, the design of the punching mechanism 7 prevents the punched card from being stuck on the inner side of the punching slot 72, thereby affecting the subsequent punching production, and further improves the production efficiency of the equipment.

[0029] The basic principles and main features of the present invention and the advantages of the present invention are shown and described above. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.
