Description

Technical Field

[0001] This utility model relates to the field of feeding and guiding technology, and in particular to a feeding and anti-deviation guiding structure for a hot press. Background Technology

[0002] When hot pressing wood composite boards and decorative veneers, the hot press precisely controls the temperature, pressure, and time to press the veneer and wood composite board together. Its core process lies in the fact that under the high temperature and pressure provided by the hot press plate, the adhesive on the back of the veneer melts, flows, and penetrates, achieving a firm, smooth, and bubble-free bonding. Ultimately, this completes the permanent adhesion between the decorative surface layer and the substrate in one step, giving the board beautiful, wear-resistant, and durable properties.

[0003] In order to improve processing efficiency, existing technologies typically use a feeding mechanism on one side of the hot press to transport the sheet metal to the working area of ​​the hot press. Traditional conveying devices usually use a simple conveyor belt to transport the sheet metal. Since the position of the hot press is fixed, the workers need to keep the position of the sheet metal uniform when placing it on the conveying device. Otherwise, some parts of the sheet metal may not be fully hot-pressed, which makes the work more difficult for the workers. Utility Model Content

[0004] Therefore, it is necessary to provide a hot press feeding anti-deviation guide structure to address the problem that traditional conveying devices cannot guide the sheet metal.

[0005] A feeding anti-deviation guide structure for a hot press includes: a mounting frame, wherein a conveyor belt and a plurality of conveyor rollers are respectively arranged inside the mounting frame;

[0006] The guiding mechanism includes a push plate and a baffle respectively disposed on both sides of the conveyor roller. A photoelectric sensor is fixedly connected to the surface of the mounting frame on the side of the baffle away from the conveyor belt, and an adjustment component is disposed below the baffle.

[0007] In one embodiment, an electric push rod is fixedly connected to the upper surface of the mounting bracket, and the drive end of the electric push rod is fixedly connected to the surface of the push plate.

[0008] In one embodiment, multiple rotating rods are provided on the inner side of both the baffle and the push plate, and an extension block is fixedly connected to the bottom end of both the baffle and the push plate.

[0009] In one embodiment, the extension block extends between every two adjacent conveyor rollers, the bottom end of the extension block below the push plate is slidably connected to the surface of the traction rod disposed below the mounting frame, the top end of the rotating rod is rotatably connected to the inside of the baffle and the push plate, and the bottom end of the rotating rod is rotatably connected to the surface of the traction block.

[0010] In one embodiment, a connecting block is fixedly connected to the outer side of the baffle, and the cross-section of the connecting block is "C" shaped.

[0011] In one embodiment, the adjustment assembly includes a positioning block fixedly connected to the lower surface of the mounting bracket, and a threaded block is slidably connected to one end of the inner wall of the positioning block near the connecting block.

[0012] In one embodiment, a positioning block extends from the bottom of the threaded block and is fixedly connected to the inner side of the connecting block. A threaded rod is rotatably connected to the inner wall of the positioning block, and the threaded block is disposed on the surface of the threaded rod.

[0013] In one embodiment, a servo motor is installed on the inner wall of the positioning block, and the drive end of the servo motor is fixedly connected to one end of the threaded rod.

[0014] Beneficial effects

[0015] 1. By setting push plates and baffles on both sides of the rotating roller, the material is sensed when passing through the roller and pushed by the push plates to one side of the baffle, making the side of the material parallel to the baffle. This can automatically and accurately correct the conveying position and posture of the material, ensuring that all materials enter the hot pressing area in a uniform posture. This greatly reduces quality problems such as uneven hot pressing and product scrap caused by manual placement deviations, significantly reduces the labor intensity and skill requirements of operators, and greatly improves production efficiency and product quality consistency.

[0016] 2. By setting an adjustment component below the baffle to adjust the position of the baffle above the roller, the guide structure can flexibly adapt to the processing needs of plates of different widths. The reference position of the baffle can be quickly and accurately set by simply adjusting the component, realizing precise limiting and guiding of plates of different sizes on the same equipment. This greatly improves the versatility and production flexibility of the equipment, effectively avoids the cumbersome mechanical adjustments or disassembly required due to changing product specifications, significantly shortens preparation time, and improves the overall efficiency of the production line.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] The following is combined Figure 1 - Figure 5 This invention describes the feeding anti-deviation guide structure for a hot press.

[0027] In one embodiment, a hot press feeding anti-deviation guide structure includes: a mounting frame 100, and a conveyor belt 200 and a plurality of conveyor rollers 210 are respectively disposed inside the mounting frame 100;

[0028] The guiding mechanism 300 includes a push plate 310 and a baffle 320 respectively disposed on both sides of the conveyor roller 210. A photoelectric sensor 340 is fixedly connected to the surface of the mounting frame 100 on the side of the baffle 320 away from the conveyor belt 200. An adjustment component 350 is disposed below the baffle 320.

[0029] In this device, the conveyor belt 200 is internally supported by multiple rotatably connected to the mounting frame 100, and has drive rollers at both ends. The drive rollers at both ends are connected by gears and racks. One of the drive rollers is driven by a drive motor, thereby causing the conveyor belt 200 to rotate as a whole. The friction force causes the plate to move on its surface. The inner wall of each idler roller is fixedly connected to a drive shaft. One end of the drive shaft is fixedly connected to a gear. Multiple gears are connected by racks. One end of the gear is connected to the drive end of the drive motor. The drive motor drives one gear to rotate, thereby driving all the gears to rotate, so that multiple rollers rotate synchronously. The surface of the rollers is also provided with rubber friction pads to increase the friction with the plate. The surface of the plate is relatively smooth when it comes out of the factory, and there will be no excessive wear on the friction pads of the rollers during transverse movement. The friction pads will wear out normally.

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an electric push rod 311 is fixedly connected to the upper surface of the mounting frame 100, and the drive end of the electric push rod 311 is fixedly connected to the surface of the push plate 310. Multiple rotating rods 330 are provided on the inner sides of both the baffle 320 and the push plate 310, and extension blocks 331 are fixedly connected to the bottom ends of both the baffle 320 and the push plate 310. The extension blocks 331 extend between every two adjacent conveying rollers 210. The bottom end of the extension block 331 below the push plate 310 is slidably connected to the surface of the traction rod provided below the mounting frame 100. The top end of the rotating rod 330 is rotatably connected to the inner sides of the baffle 320 and the push plate 310, and the bottom end of the rotating rod 330 is rotatably connected to the surface of the traction block. A connecting block 321 is fixedly connected to the outer side of the baffle 320, and the cross-section of the connecting block 321 is C-shaped.

[0031] In this embodiment, the photoelectric sensor 340 is a T18AW3REQI through-beam photoelectric sensor 340, consisting of a separate transmitter and receiver. The transmitter continuously emits a modulated light beam, and the receiver receives the light beam at a directly opposite position. When the plate passes between them, it completely blocks the light beam, causing a sudden change in the receiver signal state, thereby generating a switch signal that is fed back to the controller. After receiving the signal, the controller activates the electric push rod 311. After the electric push rod 311 is activated, it pushes the push plate 310 to move. At this time, the multiple extension blocks 331 corresponding to the bottom of the push plate 310 slide along the traction rod at the bottom of the mounting bracket 100, and the traction baffle 3... 20 moves in a straight line. When the electric push rod 311 moves a certain distance, it stops moving. This distance can be adjusted by the controller. When the push plate 310 pushes the plate to contact the surface of the rotating rod 330 on the surface of the baffle 320 through the rotating rod 330 on its surface, the electric push rod 311 closes. At this time, the plate moves in a straight line along the rotating rollers on both sides under the power provided by the rotating rollers, and finally enters the hot pressing area of ​​the hot press. When the plate completely leaves between the photoelectric sensors 340, the photoelectric sensors 340 receive the light beam again and feed it back to the controller through an electrical signal. The controller drives the electric push rod 311 to reset. The controller is a PLC controller.

[0032] It should be noted that this device, by setting guide mechanisms 300 on both sides of the rotating roller of the mounting frame 100, and the guide mechanisms 300 are all set on the surface of the mounting frame 100 on both sides of the rotating roller and installed at the bottom of the mounting frame 100 through multiple rotating rollers, will not cause any obstruction to the normal installation and operation of the rotating roller, the conveyor belt 200 and the mounting frame 100. Furthermore, this device only provides guidance for the sheet material and will not hinder its normal movement or subsequent hot pressing operation. Therefore, it will not have any impact on the normal conveying and hot pressing of the sheet material.

[0033] like Figure 1 , Figure 2 and Figure 5 As shown, the adjustment assembly 350 includes a positioning block 351 fixedly connected to the lower surface of the mounting bracket 100. A threaded block 354 is slidably connected to one end of the inner wall of the positioning block 351 near the connecting block 321. The bottom of the threaded block 354 extends out of the positioning block 351 and is fixedly connected to the inner side of the connecting block 321. A threaded rod 352 is rotatably connected to the inner wall of the positioning block 351, and the threaded block 354 is disposed on the surface of the threaded rod 352. A servo motor 353 is mounted on the inner wall of the positioning block 351, and the drive end of the servo motor 353 is fixedly connected to one end of the threaded rod 352.

[0034] In this embodiment, when the operator needs to process different plates, because the width of the plates is different, but the center line of the plate needs to be consistent with the center line of the hot pressing area, the position of the baffle 320 needs to be adjusted by adjusting component 350 to align the plate with the processing area. At this time, the operator starts the servo motor 353 through the controller. The servo motor 353 drives the threaded rod 352 to rotate. While the threaded rod 352 rotates, it drives the threaded block 354 to move along its surface inside the positioning block 351. While the threaded block 354 moves, it drives the baffle 320 to move a safe distance above the roller through the connecting block 321.

[0035] The worker roughly places the sheet material near the center of the conveyor belt 200, which then moves the sheet material towards the rotating rollers. Once inside the roller area, the sheet material is conveyed by multiple rollers through the guide mechanism 300. During this process, once the front end of the sheet material reaches the sensing area of ​​the photoelectric sensor 340, the sensor immediately detects the material and sends an electrical signal back to the controller. At this point, the middle part of the sheet material is within the movement range of the push plate 310, and the controller activates the electric push rod 311. The electric push rod 311 drives the push plate 310 towards the side of the sheet material, pushing it towards the baffle 320. With the continuous pushing of the push plate 310 and the limiting action of the baffle 320, the sides of the sheet material are gradually adjusted to be completely parallel to both the baffle 320 and the push plate 310. Subsequently, under the continuous movement of the rotating rollers, the sheet material moves directionally along the baffle 320, finally entering the hot press working area at the calibrated position to complete the hot pressing process.

[0036] It should be noted that the mounting bracket 100, conveyor belt 200, rotating roller, electric push rod 311, threaded rod 352, servo motor 353, and photoelectric sensor 340 mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs. At the same time, the power supply for the conveyor belt 200, rotating roller, drive motor, electric push rod 311, and photoelectric sensor 340 can be powered by the built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0037] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
