Description

Technical Field

[0001] This utility model relates to the field of structural foam processing technology, specifically to an auxiliary device for bonding PVC foam scraps. Background Technology

[0002] PVC foam board, also known as polyvinyl chloride foam board, has a micro-closed-cell structure and is mainly used as the structural core material for wind turbine blades, building walls, roof insulation, composite board insulation, and thermal insulation for cold storage, air conditioning, vehicles, and ships. The initial PVC foam board is rectangular or cubic with a rigid, connective skin and irregular edges. During processing, the four edges of the board need to be trimmed, and the top and bottom surfaces need to be sanded. Multiple processing cycles are required to meet the board's shape requirements. These processes leave a large amount of scrap material that cannot be effectively utilized. Existing scrap material application techniques are difficult to operate, time-consuming, have low yield rates, and are prone to injury if handled manually.

[0003] Currently, according to the Chinese invention patent with application number "CN202120928242.2", when bonding PVC foam scraps in the prior art, continuous splicing in the length direction can be achieved. However, when the width dimension is small and there are many of them, it is difficult to work continuously by pressing the roller alone. It has poor compatibility with foam boards of different specifications and requires manual material laying and feeding, which is inefficient and difficult to process. Utility Model Content

[0020] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0021] In the existing technology, the process of applying leftover material to foam boards has poor compatibility with different specifications, requires manual application and feeding, which is inefficient and difficult to process.

[0022] To address the aforementioned issues, one embodiment of this utility model provides an auxiliary device for bonding PVC foam residue, comprising a device frame 1, a feeding mechanism 7 on the right side of the device frame 1, a feeding push assembly 9 below the device frame 1 for feeding material to the bonding machine 6, a side positioning ruler 10 on the left side of the device frame 1 for positioning the reference edge of the material, a movable pressure plate 11 between the feeding mechanism 7 and the side positioning ruler 10 for adjusting the height to accommodate boards of different thicknesses, and a roller 12 between the device frame 1 and the bonding machine 6 for fixing the discharge end.

[0023] In this embodiment, as Figure 1 As shown, in order to ensure that the feeding boards are arranged flat and tightly and to achieve overall automation of the device, the equipment frame 1 is set as an integral frame, which can support the boards. On this basis, a feeding mechanism 7 is provided on the right side of the equipment frame 1, a feeding push component 9 is provided below the equipment frame 1, a side positioning ruler 10 is provided on the left side of the equipment frame 1, a movable pressure plate 11 is provided between the feeding mechanism 7 and the side positioning ruler 10, and a roller 12 is provided between the equipment frame 1 and the bonding machine 6. In this way, the feeding mechanism 7 arranges the remaining boards 14 to be bonded on the equipment frame 1, and the feeding push component 9 pushes the boards on the equipment frame 1 to the bottom of the bonding machine pressure roller. The boards continue to move forward under the drive of the pressure roller. The movable pressure plate 11 is adjusted to a suitable height to limit the warping of the boards during the feeding process. The side positioning ruler 10 limits the perpendicularity of the boards to the conveying direction to ensure that the finished boards are square and not twisted after bonding. The roller 12 fixes the discharge end to prevent the boards to be bonded from deviating. It can effectively reduce the processing difficulty of fabrication board making from leftover materials, realize the mechanization and automation of material discharge and feeding processes, improve the utilization rate of raw materials, reduce material waste, save labor costs, and improve the production efficiency and product utilization rate of PVC foam board making process.

[0024] Optionally, the equipment frame 1 includes a workbench 2 and support columns 3 fixedly connected to the four corners of the workbench 2. A vacuum adsorption device 5 is provided under the workbench, and height-adjustable feet 4 are provided under the support columns to adjust the PVC foam residue bonding auxiliary device to abut against the feed end of the applicator 6.

[0025] Specifically, such as Figure 3 As shown, the height-adjustable foot cup 4 is made of metal, and for example, the base of the height-adjustable foot cup 4 is a circular base.

[0026] In this optional embodiment, such as Figure 3 As shown, in order to ensure that the height of the PVC foam residue bonding auxiliary device is consistent with that of the feeding end of the applicator and to ensure the stability of the board feeding, the equipment frame 1 consists of a workbench 2, which is fixedly installed on the support column 3. The support column 3 is equipped with a height-adjustable foot cup 4. With this configuration, the foot cup can be raised and lowered by rotating the adjustment thread. The height and level can be adjusted to be consistent with the height of the feeding end of the applicator 6. The base of the foot cup is in contact with the ground, which has a certain load-bearing capacity and stability to ensure the stability of the equipment. On this basis, a vacuum adsorption device 5 is set under the workbench 2. The vacuum adsorption device 5 includes a fan and a vacuum solenoid valve to ensure continuous adsorption of the board during the feeding process and prevent the board from shifting.

[0027] Optionally, the feeding mechanism 7 includes a magazine assembly, which includes a magazine body for accommodating sheet metal, a height-adjustable baffle located on the left side of the magazine body, an adjusting screw threadedly connected to the height-adjustable baffle 8, and an adjusting motor for driving the adjusting screw to rotate to change the height of the height-adjustable baffle 8 and adapt to sheet metal of different thicknesses. The conveying track is connected to the magazine assembly, and the conveying track is provided with a push block for pushing the sheet metal. A rodless cylinder is connected to the push block and provides power to the push block, so that the push block pushes the sheet metal forward on the conveying track. The positioning, clamping and control system consists of a PLC, a position sensor and a gripper cylinder. The PLC is connected to the position sensor and the gripper cylinder respectively, and the PLC is also connected to the rodless cylinder.

[0028] In this optional embodiment, such as Figures 4 to 5 As shown, during the feeding process, the remaining material 14 to be bonded is placed in the feeding mechanism 7 according to its thickness direction. The feeding mechanism 7 is a pneumatic magazine-type feeding mechanism. When the equipment is started, according to the actual thickness of the material, a command is sent to the adjusting motor through the control terminal. The adjusting motor responds to the command and starts working. Its output shaft drives the adjusting screw to rotate. Since the adjusting screw is threadedly connected to the height-adjustable baffle 8, the height-adjustable baffle 8 moves smoothly along the axial direction of the screw under the rotation of the screw, thereby adapting to materials of different thicknesses and ensuring that the materials can be neatly stacked in the magazine body. After the material is placed in the magazine body, the feeding process is started, and the rodless cylinder is positioned in the clamp. Under the control of the tightness control system, the machine starts working, pushing the connected pusher block. The pusher block moves on the conveyor track, pushing the sheet metal in the magazine assembly onto the conveyor track. During the sheet metal conveying process, the position sensor monitors the position information of the sheet metal in real time and transmits the data to the PLC. When the sheet metal reaches the predetermined position, the PLC controls the gripper cylinder to move. The gripper cylinder drives the gripper to quickly clamp the sheet metal to achieve precise positioning. At this time, the rodless cylinder stops moving and waits for subsequent processing instructions. When the processing step is completed, the gripper cylinder releases the sheet metal, and the rodless cylinder starts again, pushing the pusher block to continue conveying the next sheet metal. This cycle is repeated to achieve efficient and precise feeding operation.

[0029] Optionally, the feeding drive assembly 9 includes a servo motor and a ball screw. The servo motor drives the ball screw via a coupling to push the board material into the feed, and the feeding speed is synchronized with that of the applicator 6.

[0030] In this optional embodiment, such as Figures 4 to 5 As shown, during the feeding process, when the overall width of the board 14 to be arranged reaches the set requirement, the feeding mechanism 7 stops operating. The servo motor of the feeding push component 9 drives the ball screw through the coupling, converting the rotational motion of the motor into linear motion, and smoothly pushes the board to feed accurately. Under the drive of the servo motor, the feeding push component 9 pushes the neatly arranged board towards the pressure roller of the pasting equipment at the same linear speed as the pasting machine 6, and feeds the material at a uniform speed.

[0031] Optionally, the side positioning ruler 10 is made of aluminum profile and is fixedly connected to the equipment frame 1 by set screws.

[0032] In this optional embodiment, such as Figures 3 to 5 As shown, the top screw fixes the side positioning ruler 10 to the left side of the equipment frame 1. The side positioning ruler 10 is used to limit the perpendicularity of the board to the conveying direction, so as to ensure that the finished board is square and not twisted after bonding.

[0033] Optionally, the movable pressure plate 11 and the roller body 12 are assembled with the equipment frame 1 using an adjustable mechanism.

[0034] In this optional embodiment, such as Figures 3 to 5 As shown, the movable pressure plate 11 and roller 12 are assembled with the equipment frame 1 using an adjustable mechanism. The adjustable mechanism uses a bolt and elongated hole structure to realize the position adjustment and fastening of the movable pressure plate 11 and roller 12. The movable pressure plate 11 and roller 12 are connected to the adjustable mechanism by bolts. The movable pressure plate 11 and roller 12 are adjusted to a suitable height by the adjustable mechanism. During the feeding process, the movable pressure plate 11 restricts the warping of the board during the feeding process, so that the board is arranged flat and tightly. During the feeding process, the roller 12 is used to fix the discharge end to prevent the board to be bonded from deviating.

[0035] This invention effectively reduces the processing difficulty of fabrication board making from leftover materials, realizes the mechanization and automation of the material discharge and feeding process, thereby improving the utilization rate of raw materials, reducing material waste, saving labor costs, and improving the production efficiency and product utilization rate of PVC foam board making process.
