DETAILED DESCRIPTION

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] The utility model embodiment discloses a paper tray forming device with an automatic taking-out function.

[0027] The utility model provides Figure 1-3The paper tray forming device with automatic taking-out function shown in the figure includes a frame 1 and a forming platform 2 fixedly arranged at the lower end of the frame 1, a discharge port is opened inside the forming platform 2, sliding holes are opened at both ends of the forming platform 2, two symmetrically arranged forming templates 3 are provided on the top contact of the forming platform 2, a forming cavity is opened inside the forming template 3, a hydraulic cylinder 4 is fixedly penetrated at the upper end of the inner part of the frame 1, a push rod 5 is fixedly arranged at the end of the piston rod of the hydraulic cylinder 4, an extrusion forming plate 6 is fixedly arranged at the bottom of the push rod 5, and the extrusion forming plate 6 is arranged in cooperation with the forming cavity, a through hole is opened at the lower end of one side of the frame 1, and a belt conveyor 21 is fixedly arranged between the lower end of the other side of the frame 1 and the through hole.

[0028] Before forming the paper tray, the two forming templates 3 are closed, and the forming raw materials can be filled into the forming cavity at this time. Then the hydraulic cylinder 4 is started, so that the push rod 5 can be pushed to drive the extrusion forming plate 6 to move down and extend into the forming cavity to extrude the raw materials inside the forming cavity. After the paper tray is formed, the extrusion forming plate 6 moves up, and then the two forming templates 6 move away from each other, so that the formed paper tray inside the forming cavity can fall by its own gravity and fall to the surface of the belt conveyor 21 through the discharge port, and then be transported outward by the belt conveyor 21, completing the automatic removal of the paper tray and reducing manual intervention.

[0029] After the extrusion forming plate 6 is separated from the forming template 3, the two forming templates 3 can be separated from each other and the paper tray can be unloaded autonomously, such as Figure 1-3 As shown, both sides of the inner wall of the frame 1 are provided with a separation and unloading mechanism, which includes a push plate 7, which is fixedly sleeved on the outer side of the push rod 5, a mounting plate 8 is fixedly provided on the upper end of the inner wall of the frame 1, a mounting rod 9 is fixedly provided inside the mounting plate 8, a cam 10 is rotatably sleeved on the rod wall of the mounting rod 9, the cam 10 is matched with the push plate 7, a torsion spring 11 is sleeved on the rod wall of the mounting rod 9, and both ends of the torsion spring 11 are fixedly connected to the mounting rod 9 and the cam 10 respectively, a connecting ring 12 is fixedly provided on the top of the forming template 3, a clamping ring 13 is rotatably sleeved on the inner upper end of the connecting ring 12, and a pull rope 14 is fixedly provided between the clamping ring 13 and the cam 10.

[0030] When the extrusion molding plate 6 moves up and away from the molding template 3, the push plate 7 of the rod wall of the push rod 5 contacts the two cams 10. As the push plate 7 continues to move up, the cam 10 is pushed and rotates around the mounting rod 9 and twists the torsion spring 11. When the cam 10 rotates, the cam 10 can pull the pull rope 14, so that under the snap-fit ​​cooperation of the connecting ring 12 and the snap ring 13, the pull rope 14 pulls the molding template 3, so that the two molding templates 3 can move along the molding platform 2 and away from each other. At this time, the molding paper support separates from the two molding templates 3 and falls, and when the push plate 7 moves down to push the cam 10, the cam 10 swings downward to make the pull rope 14 bend and unable to pull the molding template 3, so that the extrusion molding plate 6 can stably cooperate with the two molding templates 3 to complete the molding of the paper support.

[0031] In order to ensure that the molding template 3 moves stably on the molding platform 2 after being pulled, Figure 1-2 As shown, an elastic sliding mechanism is provided between the forming template 3 and the sliding hole, and the elastic sliding mechanism includes a vertical plate 15, the vertical plate 15 is slidably arranged in the sliding hole, a guide rod 16 is fixedly arranged in the sliding hole, the vertical plate 15 is slidably sleeved on the outer side of the guide rod 16, and the rod wall of the guide rod 16 is sleeved with a first spring 17, and the two ends of the first spring 17 are respectively fixedly connected to the vertical plate 15 and the inner wall of the sliding hole.

[0032] After the forming template 3 is pulled, the forming template 3 moves stably and squeezes the first spring 17 under the sliding cooperation of the vertical plate 15 and the guide rod 16, ensuring the stable movement of the forming template 3. At the same time, after the cam 10 is separated from the push plate 7, the elastic force of the first spring 17 can restore the two forming templates 3 to their original positions and be used in combination.

[0033] In order to avoid the adhesion of the forming paper support to the inner wall of the forming cavity and the inability to cut the material, Figure 1-2 As shown, a push hole is opened inside the forming template 3, and a cross bar 18 is slidably penetrated in the push hole. The end of the cross bar 18 is located in the same vertical line as the inner wall of the forming cavity. A second spring 19 is sleeved on the rod wall of the cross bar 18, and the two ends of the second spring 19 are respectively fixedly connected to the forming template 3 and the cross bar 18. A stopper 20 is fixedly provided at the lower end of the inner wall of the frame 1, and the cross bar 18 and the stopper 20 are arranged in coordination.

[0034] When the forming template 3 moves, the forming template 3 drives the cross bar 18 to move synchronously, and during the continuous movement of the forming template 3, the cross bar 18 contacts the stop block 20 so that the cross bar 18 is pushed and passes through the pushing hole. At this time, if there is a forming paper holder adhered to the inner wall of the forming cavity, the cross bar 18 can push the paper holder so that the paper holder can be separated from the forming cavity and fall, thereby ensuring the effect of the paper holder being taken out independently.

[0035] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
