Description

Technical Field

[0001] This utility model relates to the field of paper tray packaging manufacturing technology, specifically to a double-cylinder, double-station paper tray forming machine. Background Technology

[0002] Existing paper tray forming machines use the rising and falling of the lower mold to open and close with the upper mold. For example, Chinese Patent No. ZL202111418405.3 discloses a dual-station paper tray forming machine. When the piston rod of the cylinder retracts, it drives the lower mold lifting frame and the lower mold to move upward. The chain on the lower mold lifting frame moves synchronously with the lower mold lifting frame, and at the same time drives the encoder to move. The piston rod retracts to drive the lower mold to rise. The lower mold has a large descent space, resulting in a relatively high overall machine height. Utility Model Content

[0003] This utility model proposes a double-cylinder, double-station paper tray forming machine. By adopting an inverted lifting cylinder structure (the piston rod drives the lower template to rise when extended, and drives the lower template to fall when retracted), the distance between the lower template and the upper template does not need to be too large when the lower template is in the waiting position. When the piston rod extends, it drives the lifting cylinder body and the lower template to rise together. When the lifting cylinder body and the lower template are in the waiting state, the overall height of the paper tray forming machine will not be too high, which facilitates packaging and transportation, saves frame material, and further reduces production costs.

[0004] A dual-cylinder, dual-station paper tray forming machine designed for this purpose includes a frame with two spaced-apart paper tray forming stations. Each paper tray forming station has a fixed support assembly, a movable plate assembly, an upper mold plate, and a lower mold plate. The fixed support assembly is fixed to the frame, and the movable plate assembly is connected to the upper mold plate. The fixed support assembly has a lifting cylinder for driving the lower mold plate to move up and down, thereby realizing the opening and closing action between the upper and lower molds. The lifting cylinder has a piston rod in a telescopic state. When the piston rod is extended, it drives the lower mold plate to move upward; when the piston rod is retracted, it drives the lower mold plate to move downward.

[0005] The movable plate assembly is reciprocatingly and laterally slidably mounted on the fixed support assembly and has a pending position and a discharge position. The fixed support assembly is equipped with a motor, which is connected to the movable plate assembly in a transmission manner. The motor drives the movable plate assembly to slide on the fixed support assembly along the direction of the pending position or the discharge position.

[0006] The outer side of the frame is equipped with a receiving assembly for each paper tray forming station. The movable plate assembly and the upper template slide along the unloading position direction under the drive of the motor. When the movable plate assembly and the upper template slide to the unloading position, the receiving assembly receives the formed workpiece attached to the upper template.

[0007] The upper mold plate is provided with a pipe joint for connecting a vacuum pump. One end of the pipe joint is connected to the mold cavity of the upper mold plate, and the other end of the pipe joint is connected to the vacuum pump. After the molded workpiece is produced when the upper and lower molds are closed, the molded workpiece is attached to the mold cavity of the upper mold plate by the suction action of the vacuum pump.

[0008] The fixed support assembly includes two fixed crossbeams spaced apart at the front and rear. The motor is fixed on one of the crossbeams, and a lead screw seat is provided on the other crossbeam. A lead screw is provided between the lead screw seat and the motor. One end of the lead screw is inserted into the lead screw seat, and the other end of the lead screw is connected to the drive shaft of the motor. A lead screw nut is provided on the lead screw, and the lead screw nut is sleeved on the lead screw. The movable plate assembly includes a fixed block connected to the lead screw nut. The motor is connected to the movable plate assembly through the threaded transmission between the lead screw and the lead screw nut.

[0009] The fixed support assembly includes a fixed base and a lifting plate for supporting the fixed lifting cylinder. A plurality of lifting guide rods are provided between the fixed base and the lifting plate. Each lifting guide rod is inserted into the fixed base and the lifting plate, and one end of each lifting guide rod is connected to the lifting plate, and the other end of each lifting guide rod is connected to the lower template. One end of the piston rod of the lifting cylinder abuts against the fixed base. When the piston rod of the lifting cylinder moves in extension and retraction, it drives the lifting plate, the lifting guide rods and the lifting plate to move up and down.

[0010] The fixed bracket assembly includes two longitudinal fixed beams spaced apart on the left and right, each longitudinal fixed beam is provided with a slide rail, and the bottom of the movable plate assembly is provided with a slider that slides with the slide rail. The movable plate assembly is reciprocally mounted on the fixed bracket assembly through the sliding engagement between the slider and the slide rail.

[0011] The frame is equipped with a guardrail assembly for enclosing the fixed support assembly.

[0012] The frame is provided with an opening, and a receiving assembly is provided on the outside of each paper tray forming station. The movable plate assembly is reciprocated and laterally slidable on the fixed support assembly. When the movable plate assembly drives the upper template to slide along the direction of the receiving assembly, the receiving assembly receives the formed workpiece attached to the upper template through the opening.

[0013] The receiving assembly includes a receiving frame, a receiving lifting cylinder, and a receiving lifting plate. The receiving lifting cylinder is fixed inside the receiving frame. One end of the piston rod of the receiving lifting cylinder is connected to the receiving lifting plate. A receiving lifting guide rod is provided between the receiving frame and the receiving lifting plate. The receiving lifting guide rod is inserted into the receiving frame, and one end of the receiving lifting guide rod is connected to the receiving lifting plate.

[0014] The beneficial technical effects of this utility model are as follows:

[0015] By adopting an inverted lifting cylinder structure (the piston rod drives the lower template to rise when extended, and drives the lower template to fall when retracted), the distance between the lower template and the upper template does not need to be too large when the lower template is in the waiting position. When the piston rod extends, it drives the lifting cylinder body and the lower template to rise together. When the lifting cylinder body and the lower template are in the waiting state, the overall height of the paper tray forming machine will not be too high, which facilitates packaging and transportation, saves frame material, and further reduces production costs.

However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0025] See Figures 1-7A dual-cylinder, dual-station paper tray forming machine includes a frame 1 with two spaced-apart paper tray forming stations 2. Each paper tray forming station 2 has a fixed support assembly 3, a movable plate assembly 4, an upper template 5, and a lower template 6. The fixed support assembly 3 is fixed to the frame 1, and the movable plate assembly 4 is connected to the upper template 5. The fixed support assembly 3 is equipped with a lifting cylinder 7 for driving the lower template 6 to move up and down, thereby realizing the opening and closing action between the upper and lower templates. The lifting cylinder 7 has a piston rod in a telescopic state. When the piston rod is extended, it drives the lower template 6 to move upward; when the piston rod is retracted, it drives the lower template 6 to move downward.

[0026] The movable plate assembly 4 is reciprocated and laterally slidably mounted on the fixed bracket assembly 3 and has a pending position and a discharge position. The fixed bracket assembly 3 is equipped with a motor 8, which is connected to the movable plate assembly 4 in a transmission manner. The motor 8 drives the movable plate assembly 4 to slide on the fixed bracket assembly 3 along the direction of the pending position or the discharge position.

[0027] The outer side of the frame 1 is provided with a receiving assembly 9 corresponding to each paper tray forming station 2. The movable plate assembly 4 and the upper template 5 slide along the unloading position direction under the drive of the motor 8. The movable plate assembly 4 and the upper template 5 slide to the unloading position, and the receiving assembly 9 receives the formed workpiece attached to the upper template 5.

[0028] The upper mold plate 5 is provided with a pipe joint for connecting a vacuum pump. One end of the pipe joint is connected to the mold cavity of the upper mold plate 5, and the other end of the pipe joint is connected to the vacuum pump. After the molded workpiece is generated in the state of the upper and lower molds being closed, the molded workpiece is attached to the mold cavity of the upper mold plate 5 by the suction action of the vacuum pump.

[0029] The fixed support assembly 3 includes two fixed crossbeams 10 spaced apart at the front and rear. The motor 8 is fixed on one of the crossbeams 10, and the other crossbeam 10 is provided with a lead screw seat 11. A lead screw 12 is provided between the lead screw seat 11 and the motor 8. One end of the lead screw 12 is inserted into the lead screw seat 11, and the other end of the lead screw 12 is connected to the drive shaft of the motor 8. A lead screw nut 13 is provided on the lead screw 12 and is sleeved on the lead screw 12. The movable plate assembly 4 includes a fixed block 14 connected to the lead screw nut 13. The motor 8 is connected to the movable plate assembly 4 through the threaded transmission between the lead screw 12 and the lead screw nut 13.

[0030] The fixed support assembly 3 includes a fixed base 15 and a lifting plate 16 for supporting the fixed lifting cylinder 7. A plurality of lifting guide rods 17 are provided between the fixed base 15 and the lifting plate 16. Each lifting guide rod 17 is inserted into the fixed base 15 and the lifting plate 16, and one end of each lifting guide rod 17 is connected to the lifting plate 16, and the other end of each lifting guide rod 17 is connected to the lower template 6. One end of the piston rod of the lifting cylinder 7 abuts against the fixed base 15. When the piston rod of the lifting cylinder 7 moves in extension and retraction, it drives the lifting plate 16, the lifting guide rods 17 and the lifting plate 16 to move up and down.

[0031] The fixed bracket assembly 3 includes two longitudinal fixed beams 18 spaced apart on the left and right. Each longitudinal fixed beam 18 is provided with a slide rail 19. The bottom of the movable plate assembly 4 is provided with a slider 20 that slides with the slide rail 19. The movable plate assembly 4 is reciprocally mounted on the fixed bracket assembly 3 through the sliding engagement between the slider 20 and the slide rail 19.

[0032] In this embodiment, the longitudinal fixed beam 18 has side connecting blocks on both its left and right sides that connect to the fixed seat 15. The side connecting blocks extend laterally and are disposed on the outer side of the longitudinal fixed beam 18. The bottom of one side of the fixed seat 15 is fixed to the side connecting blocks. The cylinder body of the lifting cylinder 7 is fixed on the lifting plate 16. The piston rod of the lifting cylinder 7 passes through the lifting plate 16 and abuts against the top of the fixed seat 15. Since the fixed seat 15 is stationary, when the piston rod of the lifting cylinder 7 extends, the cylinder body of the lifting cylinder 7 moves upward, the lifting plate 16 moves upward with the cylinder body of the lifting cylinder 7, and the lifting guide rod 17 and the lower template 6 move upward accordingly. Conversely, when the piston rod of the lifting cylinder 7 retracts, the lower template 6 moves downward.

[0033] In this embodiment, a lifting guide sleeve for inserting the lifting guide rod 17 is provided on the side connecting block. The lifting guide sleeve is fixed to the side connecting block by screws.

[0034] In this embodiment, the slide rail 19 is a cylindrical guide rail, and the bottom of the cylindrical guide rail is provided with a guide rail fixing block that is fixed to the longitudinal fixing beam 18 by screws. The slider 20 has a square structure, and the square slider 20 is provided with an arc-shaped mating groove that mates with the cylindrical guide rail.

[0035] In this embodiment, the slider 20 is fixed to the bottom of the movable plate assembly 4 by screws. The bottom of the movable plate assembly 4 is provided with connecting rods that extend downwards towards the upper template 5 and are connected to the upper template 5. There are four connecting rods, and one end of each rod is provided with a pad that connects to the upper template 5. The upper template 5 is fixed to the pad with screws. The pad can be connected to the connecting rod via bolts.

[0036] The frame 1 is provided with a guardrail assembly 21 for enclosing the fixed support assembly 3.

[0037] In this embodiment, the guardrail assembly 21 includes a front side panel and side guardrail panels disposed on the left and right sides of the front side panel.

[0038] The guardrail assembly 21 serves a protective function, preventing users from approaching the fixed support assembly 3 on the one hand, and preventing the fixed assembly 3 from falling out of the frame 1 on the other hand.

[0039] The frame 1 is provided with an opening 22. A receiving assembly 9 is provided on the outside of the opening 22 corresponding to each paper tray forming station 2. The movable plate assembly 4 is reciprocated and slid laterally on the fixed support assembly 3. When the movable plate assembly 4 drives the upper template 5 to slide along the direction of the receiving assembly 9, the receiving assembly 9 receives the formed workpiece attached to the upper template 5 through the opening 22.

[0040] The opening 22 forms an opening and clearance section for the receiving assembly 9 to receive the molded workpiece. The receiving assembly 9 is equipped with a detector for detecting the workpiece. When the detector detects that the molded workpiece is above the receiving assembly 9, the receiving lifting cylinder 24 drives the receiving lifting plate 25 to rise, and the vacuum pump releases gas, causing the molded workpiece attached to the upper template 5 to fall onto the receiving lifting plate 25. Then, the receiving lifting cylinder 24 of the receiving assembly 9 drives the receiving lifting plate 25 to descend and reset. Finally, the molded workpiece can be manually removed from the receiving lifting plate 25.

[0041] The receiving assembly 9 includes a receiving fixing frame 23, a receiving lifting cylinder 24, and a receiving lifting plate 25. The receiving lifting cylinder 24 is fixed inside the receiving fixing frame 23. One end of the piston rod of the receiving lifting cylinder 24 is connected to the receiving lifting plate 25. A receiving lifting guide rod 26 is provided between the receiving fixing frame 23 and the receiving lifting plate 25. The receiving lifting guide rod 26 is inserted into the receiving fixing frame 23, and one end of the receiving lifting guide rod 26 is connected to the receiving lifting plate 25.

[0042] In this embodiment, the receiving fixing frame 23 has an installation cavity for accommodating the receiving lifting cylinder 24; the cylinder body of the receiving lifting cylinder 24 is fixed to the top wall of the installation cavity with screws. The receiving fixing frame 23 has a guide sleeve for inserting the receiving lifting guide rod 26, which is fixed to the top of the receiving fixing frame 23 with screws. The bottom of the receiving lifting plate 25 has a bottom connector, which is threadedly connected to the end of the piston rod of the receiving lifting cylinder 24 through a threaded inner cavity. When the piston rod of the receiving lifting cylinder 24 extends or retracts, it drives the receiving lifting plate 25 to rise or fall, and the receiving lifting guide rod 26 moves up and down within the guide sleeve following the movement of the receiving lifting plate 25.
