Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of PVC transparent board production equipment, and in particular to a shearing machine feeding device for PVC transparent board production. Background Technology
[0002] PVC transparent sheets are engineering plastic sheets made primarily of polyvinyl chloride resin, with the addition of transparent agents, plasticizers, and other additives, through extrusion molding. Their light transmittance can reach 85%-92% (thickness 2-10mm), and they also possess corrosion resistance, flame retardancy, and insulation properties, making them widely used in advertising signage, architectural lighting, medical devices, and other fields. The standard production process for PVC transparent sheets is as follows: raw material mixing → twin-screw extrusion → three-roll calendering and shaping → traction cooling → cutting → stacking and packaging.
[0003] In continuous production, shearing machines are used to cut infinitely long calendered sheets into PVC transparent sheets of specific sizes. The cut PVC transparent sheets are then fed into a feeding device located on one side of the shearing machine. Currently used feeding devices include conveyor belts that transport the PVC transparent sheets to a feeding stacking rack. Commercially available PVC transparent sheets range in width from 600mm to 2500mm, and end customers often require custom widths (such as 1350mm, 1800mm, etc.). The conveyor belts in current feeding devices are designed for fixed-width PVC transparent sheets, limiting their applicability. Different sized feeding devices need to be configured on-site, resulting in high manufacturing costs. Furthermore, replacing the feeding devices is time-consuming and labor-intensive, impacting production efficiency. Utility Model Content

[0021] like Figure 1-4 As shown, a shearing machine feeding device for PVC transparent sheet production includes a feeding conveying assembly 1 and a feeding stacking support 2 disposed on one side of the shearing machine.
[0022] The feeding and conveying assembly includes a main support 3 fixedly installed on the ground and auxiliary supports 4 symmetrically arranged on both sides of the main support. The lower end of the auxiliary supports is equipped with a traveling wheel 5. Both the main support and the auxiliary supports are equipped with a conveyor belt structure 6. Both ends of the main support are equipped with a position adjustment structure for driving the auxiliary supports to adjust their position. The ends of the main support near the shearing machine are equipped with a support structure 7 for supporting the PVC transparent sheet. The ends of the main support away from the shearing machine are equipped with a pushing structure 8 for pushing the PVC transparent sheet. The outer sides of the two auxiliary supports are symmetrically equipped with a positioning structure 9 for positioning the PVC transparent sheet.
[0023] The material unloading stacking support includes a stacking plate 10, with rollers 11 installed at the lower end of the stacking plate. Positioning rods 12 are installed on both sides of the stacking plate, and the height of the positioning rods near the material unloading conveyor assembly is lower than the height of the conveyor belt structure.
[0024] In this configuration, the feeding conveyor assembly is positioned on one side of the shearing machine. The shearing machine cuts the sheet metal into PVC transparent sheets, which are then conveyed to the feeding stacking bracket by the feeding conveyor assembly for stacking, completing the feeding process. Specifically, the sheet metal moves to one side of the shearing machine, where a support structure supports the PVC transparent sheets. After the shearing machine finishes cutting the PVC transparent sheets, the support structure lowers, causing the PVC transparent sheets to fall onto the conveyor belt structure. The conveyor belt structure moves the PVC transparent sheets to the end away from the shearing machine, where a pushing structure quickly pushes them onto the feeding stacking bracket. A positioning structure positions the PVC transparent sheets, ensuring they are neatly stacked on the feeding stacking bracket. A position adjustment structure is included, which moves the auxiliary bracket according to the width of the PVC transparent sheets cut by the shearing machine, adjusting the conveying width to accommodate different widths of PVC transparent sheets, thus providing a wide range of applications. The pushing assembly pushes the PVC transparent sheet to the stacking plate of the unloading stacking bracket. The lower end of the stacking plate is equipped with rollers to facilitate the transfer of the PVC transparent sheet. Positioning rods are installed on both sides of the stacking plate to position the PVC transparent sheet. The height of the positioning rods near the unloading conveyor assembly is lower than the height of the conveyor belt structure to avoid obstructing the PVC transparent sheet when it is unloaded from the conveyor belt structure.
[0025] In implementation, the position adjustment structure includes four main cylinders 13 fixedly mounted on the main support, wherein the extension direction of the cylinder rods of two main cylinders is opposite to that of the other two main cylinders. Two auxiliary cylinders 14 are fixedly mounted on each auxiliary support, directly opposite the main cylinders. Connecting seats 15 are provided on both ends of the main support, and the cylinder rods of both the main and auxiliary cylinders are fixedly connected to connecting blocks. The connecting seats connect the main and auxiliary cylinders located on both sides, and the synchronous counter-movement of the main and auxiliary cylinders enables rapid adjustment of the position of the auxiliary support.
[0026] In implementation, the support structure includes a support cylinder 16 fixedly installed on a connecting seat near the shearing machine. The cylinder rod of the support cylinder is upwardly positioned and a support block 17 is fixedly installed thereon. The support cylinder drives the support block upward to move above the conveyor belt structure to support the PVC transparent sheet. After the shearing machine finishes shearing the sheet, the support cylinder drives the support block downward, causing the PVC transparent sheet to fall onto the conveyor belt structure.
[0027] In implementation, the pushing structure includes a screw 18. A mounting slot is provided on a connecting seat located away from the shearing machine. The screw is located in the mounting slot, and one end of the screw is connected to the connecting seat via a bearing. The other end of the screw is fixedly connected to the output shaft of a servo motor 19. The servo motor is fixedly mounted on the connecting seat. A clearance opening is provided through the connecting seat facing the output shaft of the servo motor. A nut block is threaded onto the screw. The two sides of the nut block slide against the groove side of the mounting slot. A pushing bracket 20 is fixedly mounted on the nut block. A pushing cylinder 21 is fixedly mounted on the upper end of the pushing bracket. The cylinder rod of the pushing cylinder passes through the pushing bracket and a push block 22 is fixedly mounted thereon. When the PVC transparent sheet moves to the end of the conveyor belt away from the shearing machine, the cylinder rod of the pushing cylinder extends, causing the push block to rise, so that the push block is facing the PVC transparent sheet. Then, the servo motor drives the screw to rotate. Through the cooperation between the screw and the nut, and the limiting of the nut by the mounting slot, the pushing bracket moves, thereby driving the push block to push the PVC transparent sheet onto the unloading stacking bracket.
[0028] In implementation, the positioning structure includes several cylinder seats 23 fixedly installed on the outside of the sub-support. Positioning cylinders 24 are fixedly installed on the cylinder seats, and the cylinder rods of the positioning cylinders pass through the cylinder seats and are fixedly connected to the positioning plate 25. After the pushing structure moves the PVC transparent sheet onto the stacking plate, the cylinder rods of the positioning cylinders on both sides extend, causing the positioning plate to position the PVC transparent sheet, making the PVC transparent sheet more stable when stacked vertically.
[0029] In implementation, a support rod 27 is fixedly installed on the upper end of the positioning plate via a crank arm 26, and the height of the support rod is the same as the height of the transmission belt structure. When the pushing structure moves the PVC transparent plate, the support rod is positioned directly opposite the transmission belt structure on the auxiliary support. The two sides of the PVC transparent plate move onto the support rod, which supports the PVC transparent plate. When the PVC transparent plate comes into contact with the positioning rod away from the transmission belt structure, the cylinder rod of the positioning cylinder retracts, and the PVC transparent plate falls onto the stacking plate. Afterward, the positioning structure positions the PVC transparent plate.
[0030] Specifically, the conveyor belt structure includes a conveyor belt and rollers. The rollers are mounted on the main support and the auxiliary support, respectively. The conveyor belt is sleeved on the outside of the rollers. One of the rollers has a driven pulley fixed to it. The main support and the auxiliary support have driving pulleys rotatably mounted on them, corresponding to the driven pulleys. The driving pulleys are connected to the driven pulleys via belts. The driving pulleys are connected to a reduction motor mounted on the main support and the auxiliary support. The conveyor belt structure is an existing structure and can be directly assembled and used.
[0031] Finally, it should be noted that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims and their equivalents, this utility model also intends to include these modifications and variations.
