Description

Technical Field

[0001] This utility model relates to the technical field of plastic flooring production, and in particular to a plastic flooring coating and feeding mechanism. Background Technology

[0002] During the production of PVC flooring, a laminating process is required. This laminating process necessitates a feeding mechanism to transport the PVC flooring to a laminating machine. Chinese utility model patent CN218319491U discloses a conveying device for PVC flooring. This device includes a base with a conveying mechanism mounted on it. The conveying mechanism comprises four mounting plates symmetrically fixed to the upper end of the base. Two mounting plates on the same side have their sidewalls rotatably connected to conveyor rollers, which are connected by a conveyor belt. A motor is fixedly connected to the sidewall of one of the mounting plates, with the motor's output end penetrating the sidewall and fixedly connected to the conveyor roller. A fixing rod is fixedly connected to the upper end of the base, and a feeding box is fixedly connected to the sidewall of the fixing rod. PVC flooring is stacked and placed into the feeding box. The extension length of the adjusting plate is then adjusted so that the height of the feeding port is the same as the thickness of the PVC flooring, allowing for continuous, individual conveying of the stacked PVC flooring for convenient subsequent processing.

[0003] However, in the aforementioned feeding and conveying mechanism, the plastic flooring is stacked inside the feeding box. After the conveyor belt rotates and removes a plastic flooring from the feeding box, the pressure of the multiple plastic floorings stacked above it acts directly on the conveyor belt, causing the bottom plastic flooring in the feeding box to rub against the conveyor belt, resulting in wear of the plastic flooring and increasing the driving force of the conveyor belt. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a plastic flooring coating feeding mechanism that does not abrade the plastic flooring during feeding, does not increase the driving force of the conveyor belt, and has good practicality.

[0005] This utility model discloses a plastic flooring coating and feeding mechanism, comprising a frame, rollers, a conveyor belt, and a material rack. Multiple rollers are rotatably mounted on the frame, and the conveyor belt is fitted onto the rollers. The material rack is installed on the outside of the input end of the frame, and plastic flooring is stacked within it. It also includes two slides, two sliders, a crossbar, a push plate, and a drive assembly. The plastic flooring in the material rack is located above the conveyor belt. The two slides are slidably mounted on the left and right sides of the material rack, each with a vertical slide rail. Two sliders are slidably mounted on the slide rails of the two slides. The left and right ends of the crossbar are rotatably connected to the two sliders, and the sliders have angle limiting structures for the crossbar. A push plate is mounted in the middle of the crossbar, and the lower end of the push plate is used to push the topmost plastic flooring. The drive assembly drives the two slides to slide back and forth. During operation, multiple plastic flooring units are stacked on the material rack and move along the slides of the two slides. The guide rail raises two sliders, positioning the crossbar and push plate above multiple plastic floorboards. The lower end of the push plate aligns with the rear wall of the uppermost plastic floorboard. The drive assembly moves two carriages forward, causing them to push the uppermost plastic floorboard forward along with the sliders, crossbar, and push plate, allowing it to fall onto the conveyor belt. The two carriages then move backward to reset, and the two sliders adaptively lower by one layer of plastic floorboard, aligning the lower end of the push plate with the rear wall of the uppermost plastic floorboard again. Multiple rollers drive the conveyor belt to rotate, transporting the plastic floorboards to the laminating machine, completing the loading of one plastic floorboard. Compared to existing technologies, this method avoids abrasion on the plastic floorboards in the rack during conveyor belt transport, and the pressure of stacked plastic floorboards does not act on the conveyor belt, thus not increasing the conveyor belt's driving force, making it highly practical.

[0006] Preferably, it also includes a corner plate, which has a vertically connected vertical plate and a horizontal plate. The lower end of the vertical plate of the corner plate is connected to the lower end of the push plate, and the horizontal plate of the corner plate is located above and in front of the lower end of the push plate. When the push plate moves to the rear side of multiple plastic flooring stacked on the material rack, the horizontal plate of the corner plate rests on the rear end of the uppermost plastic flooring. At this time, the lower end of the push plate is aligned with the rear side wall of the plastic flooring, thereby positioning and limiting the lower end of the push plate and preventing the lower end of the push plate from pushing out the plastic flooring below the top, thus improving the feeding accuracy.

[0007] Preferably, it also includes two rollers, which are respectively mounted on the two sliders by brackets. The two rollers are located in front of the two sliders and roll on the uppermost plastic floor. The rolling of the two rollers on the uppermost plastic floor limits the position of the two sliders, so that the two sliders can adapt to the decrease in the number of stacked plastic floorboards.

[0008] Preferably, the angle limiting structure of the crossbar includes two shaft tubes and two limiting blocks. The two shaft tubes are respectively mounted on two sliders. Limiting slots are provided on the side walls of the two shaft tubes. The left and right ends of the crossbar are rotatably connected to the two shaft tubes. Limiting blocks are installed on the outer walls of both ends of the two shaft tubes. The two limiting blocks are located in the limiting slots of the two shaft tubes. The crossbar is rotatably connected to the two sliders through the two shaft tubes. When the crossbar rotates, it drives the two limiting blocks to rotate in the limiting slots of the two shaft tubes. This causes the two ends of the limiting slots of the two shaft tubes to limit the position of the two limiting blocks. When the pusher pushes the plastic flooring, the limiting blocks are limited and blocked by the ends of the limiting slots, improving the stability of the pusher.

[0009] Preferably, the assembly also includes a horizontal plate, a guide plate, a lead screw, a lead screw nut, and a motor. The horizontal plate is slidably mounted on the front side of the material rack. The rear end of the guide plate is rotatably connected to the front end of the horizontal plate. The front end of the guide plate rests on the conveyor belt. The lead screw is vertically and rotatably mounted on the material rack. The lead screw nut is threadedly connected to the lead screw and mounted on the horizontal plate. The motor is mounted on the material rack, and the output shaft of the motor is driven by the lead screw. The upper end face of the horizontal plate is flush with the lower end face of the uppermost plastic flooring. The motor drives the lead screw to rotate, and the threaded action of the lead screw and the lead screw nut drives the horizontal plate to rise and fall, ensuring that the upper end face of the horizontal plate is always flush with the lower end face of the uppermost plastic flooring. This allows the plastic flooring pushed out by the push plate to slide along the horizontal plate and the guide plate onto the conveyor belt, reducing impact on the plastic flooring and the conveyor belt and improving stability.

[0010] Preferably, it also includes a contact switch, which is installed at the front end of the material rack and the contacts of the contact switch are aligned with the slide. The contact switch is electrically connected to the motor controller. When the slide moves to the front end of the material rack to complete the loading of a plastic floor, the slide contacts the contacts of the contact switch, causing the contact switch to generate an electrical signal. After receiving the electrical signal, the motor controller controls the motor to rotate a certain angle to realize the step-down descent of the horizontal plate.

[0011] Preferably, the drive assembly includes a roller shaft, a transmission belt, a lever, a second slide rail, a second slider, a stop rod, a pull rod, and a tension spring. The roller shaft is rotatably mounted on the frame. The rear end of the transmission belt is fitted onto the roller wheel, and the front end of the transmission belt is fitted onto the roller shaft, with the front end of the transmission belt on the roller shaft lower than the rear end of the transmission belt on the roller wheel. The lever is mounted on the transmission belt. The second slide rail is mounted on the frame. The second slider is slidably mounted on the second slide rail. The stop rod is mounted on the second slider and aligned with the lever. The front end of the pull rod is connected to the second slider, and the rear end of the pull rod is connected to the carriage. One end of the tension spring is connected to the carriage. The other end of the spring is connected to the rear of the material rack; the roller shaft and roller wheel are fitted to rotate and install the transmission belt. The rotation of the roller wheel drives the conveyor belt and the transmission belt to rotate synchronously. When the lever is located on the upper layer of the transmission belt, the lever contacts the stop bar, thereby pushing the second slider to move forward along the second slide rail. This causes the second slider to pull the slide forward through the pull rod, storing the tension spring cable. Since the front end of the transmission belt is lower than the rear end of the transmission belt, the lever gradually descends until it disengages from the stop bar. At this time, the push plate pushes a plastic base plate onto the conveyor belt, and the elastic force of the tension spring pulls the slide back to reset, preparing for the next feeding.

[0012] Compared with the prior art, the advantages of this utility model are: the conveyor belt will not wear down the plastic flooring in the rack when conveying plastic flooring, and the pressure of multiple stacked plastic floorings will not act on the conveyor belt, thus not increasing the driving force of the conveyor belt, and it is practical.

[0020] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0021] Example 1

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, a plastic flooring coating and feeding mechanism includes a frame 1, rollers 2, a conveyor belt 3, and a material rack 4. Multiple rollers 2 are rotatably mounted on the frame 1, and the conveyor belt 3 is fitted onto the rollers 2. The material rack 4 is installed outside the input end of the frame 1, and plastic flooring is stacked in the material rack 4. It also includes two slides 5, two sliders 6, a crossbar 7, a push plate 8, and a drive assembly. The plastic flooring in the material rack 4 is located above the conveyor belt 3. The two slides 5 are slidably mounted on the left and right sides of the material rack 4, and each slide 5 is provided with a vertical slide rail. The two sliders 6 are slidably mounted on the slide rails of the two slides 5 respectively. The left and right ends of the crossbar 7 are respectively connected to... Two sliders 6 are rotatably connected. A crossbar 7 is provided on the slider 6 to limit the angle of the crossbar 7. A push plate 8 is installed in the middle of the crossbar 7. The lower end of the push plate 8 is used to push the uppermost plastic floor. A drive assembly is used to drive the two carriages 5 to slide back and forth. An angle plate 9 is also included. The angle plate 9 is provided with a vertically connected vertical plate and a horizontal plate. The lower end of the vertical plate of the angle plate 9 is connected to the lower end of the push plate 8. The horizontal plate of the angle plate 9 is located above and in front of the lower end of the push plate 8. Two rollers 10 are also included. The two rollers 10 are respectively mounted on the two sliders 6 through brackets. The two rollers 10 are located in front of the two sliders 6 and roll on the uppermost plastic floor.

[0023] During operation, multiple plastic floorboards are stacked on the rack 4. Two sliders 6 are raised along the slide rails of the two carriages 5, positioning the crossbar 7 and push plate 8 above the plastic floorboards. The lower end of the push plate 8 is aligned with the rear sidewall of the uppermost plastic floorboard. The drive assembly moves the two carriages 5 forward, causing them to push the uppermost plastic floorboard forward along with the two sliders 6, crossbar 7, and push plate 8, causing it to fall onto the conveyor belt 3. The two carriages 5 then move backward to reset, and the two rollers 10 roll on the uppermost plastic floorboard, thus defining the position of the two sliders 6. This allows the two sliders 6 to adapt to the decreasing stack of plastic floorboards, lowering by one layer of floorboard, causing the lower end of the push plate 8 to... The push plate 8 aligns with the rear wall of the topmost plastic flooring. When the push plate 8 moves to the rear of the multiple plastic floorings stacked on the rack 4, the horizontal plate of the corner plate 9 rests on the rear end of the upper surface of the topmost plastic flooring. At this time, the lower end of the push plate 8 aligns with the rear wall of the plastic flooring, thus positioning and limiting the lower end of the push plate 8 and preventing the lower end of the push plate 8 from pushing out the plastic flooring below the top. Multiple rollers 2 drive the conveyor belt 3 to rotate, so that the conveyor belt 3 transports the plastic mat to the laminating machine, completing the loading of one plastic flooring. Compared with the existing technology, the conveyor belt will not wear the plastic flooring in the rack 4 when transporting plastic flooring, and the pressure of the multiple stacked plastic floorings will not act on the conveyor belt, thus not increasing the driving force of the conveyor belt, which is practical.

[0024] Furthermore, the angle limiting structure of the crossbar 7 includes two shaft tubes 17 and two limiting blocks 18. The two shaft tubes 17 are respectively mounted on the two sliders 6. Limiting slots are provided on the side walls of the two shaft tubes 17. The left and right ends of the crossbar 7 are rotatably connected to the two shaft tubes 17. Limiting blocks 18 are installed on the outer walls of both ends of the two shaft tubes 17. The two limiting blocks 18 are located in the limiting slots of the two shaft tubes 17. The crossbar 7 is rotatably connected to the two sliders 6 through the two shaft tubes 17. When the crossbar 7 rotates, it drives the two limiting blocks 18 to rotate in the limiting slots of the two shaft tubes 17, so that the two ends of the limiting slots of the two shaft tubes 17 limit the position of the two limiting blocks 18. When the push plate 8 pushes the plastic flooring, the limiting blocks 18 are limited and blocked by the ends of the limiting slots, improving the stability of the push.

[0025] Example 2

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, based on Embodiment 1, it also includes a horizontal plate 11, a guide plate 12, a lead screw 13, a lead screw nut 14, and a motor 15. The horizontal plate 11 is slidably mounted on the front side of the material rack 4. The rear end of the guide plate 12 is rotatably connected to the front end of the horizontal plate 11. The front end of the guide plate 12 rests on the conveyor belt 3. The lead screw 13 is vertically rotatably mounted on the material rack 4. The lead screw nut 14 is threadedly connected to the lead screw 13 and is mounted on the horizontal plate 11. The motor 15 is mounted on the material rack 4. The output shaft of the motor 15 is drively connected to the lead screw 13. The upper end face of the horizontal plate 11 is flush with the lower end face of the uppermost plastic floor. It also includes a contact switch 16, which is mounted on the front end of the material rack 4. The contacts of the contact switch 16 are aligned with the slide 5.

[0027] Motor 15 drives lead screw 13 to rotate. The threaded action of lead screw 13 and lead screw nut 14 drives horizontal plate 11 to rise and fall, so that the upper end of horizontal plate 11 is always flush with the lower end of the uppermost plastic flooring. This allows the plastic flooring pushed out by push plate 8 to slide along horizontal plate 11 and guide plate 12 onto conveyor belt 3, reducing impact on plastic flooring and conveyor belt 3 and improving stability. Contact switch 16 is electrically connected to the controller of motor 15. When slide 5 moves to the front end of material rack 4 to complete the loading of one plastic flooring, slide 5 contacts the contact point of contact switch 16, causing contact switch 16 to generate an electrical signal. After receiving the electrical signal, the controller of motor 15 controls motor 15 to rotate a certain angle, realizing the step-down descent of horizontal plate 11.

[0028] Example 3

[0029] like Figures 1 to 4 As shown, based on Embodiment 1, the drive assembly includes a roller shaft 19, a transmission belt 20, a lever 21, a second slide rail 22, a second slider 23, a stop bar 24, a pull rod 25, and a tension spring 26. The roller shaft 19 is rotatably mounted on the frame 1. The rear end of the transmission belt 20 is fitted onto the roller 2, and the front end of the transmission belt 20 is fitted onto the roller shaft 19, with the front end of the transmission belt 20 on the roller shaft 19 being lower than the rear end of the transmission belt 20 on the roller 2. The lever 21 is mounted on the transmission belt 20. The second slide rail 22 is mounted on the frame 1. The second slider 23 is slidably mounted on the second slide rail 22. The stop bar 24 is mounted on the second slider 23 and is aligned with the lever 21. The front end of the pull rod 25 is connected to the second slider 23, and the rear end of the pull rod 25 is connected to the slide 5. One end of the tension spring 26 is connected to the slide 5, and the other end of the tension spring 26 is connected to the rear of the material rack 4.

[0030] The roller shaft 19 and roller 2 are used to rotate and install the transmission belt 20. The rotation of roller 2 drives the conveyor belt 3 and the transmission belt 20 to rotate synchronously. When the lever 21 is on the upper layer of the transmission belt 20, the lever 21 contacts the stop bar 24, thereby pushing the slider 23 to move forward along the slide rail 22. The slider 23 pulls the slide 5 forward through the pull rod 25, storing the tension of the tension spring 26. Since the front end of the transmission belt 20 is lower than the rear end of the transmission belt 20, the lever 21 gradually descends until it disengages from the stop bar 24. At this time, the push plate 8 pushes a plastic base plate onto the conveyor belt 3. The elastic force of the tension spring 26 pulls the slide 5 backward to reset, preparing for the next feeding.

[0031] like Figures 1 to 6 As shown, this utility model discloses a plastic flooring coating and feeding mechanism. During operation, multiple plastic flooring units are first stacked on the material rack 4. Then, two sliders 6 are raised along the slide rails of two carriages 5, causing the crossbar 7 and push plate 8 to be positioned above the multiple plastic flooring units. Two rollers 10 roll on the uppermost plastic base plate, causing the crossbar of the corner plate 9 to rest on the plastic flooring. At this time, the lower end of the push plate 8 is aligned with the rear sidewall of the uppermost plastic flooring unit. Then, the drive assembly drives the two carriages 5 to move forward, causing... The two carriages 5 drive the two sliders 6, the crossbar 7 and the push plate 8 to push the uppermost plastic flooring forward, and the plastic flooring falls along the cross plate 11 and the guide plate 12 onto the conveyor belt 3. The two sliders 6 follow the two rollers 10 to adaptively descend the height of one layer of plastic flooring, so that the lower end of the push plate 8 is aligned with the rear side wall of the uppermost plastic flooring again. Finally, the multiple rollers 2 drive the conveyor belt 3 to rotate, so that the conveyor belt 3 transports the plastic mat to the laminating machine, thus completing the loading of one plastic flooring.

[0032] The main functions achieved by this utility model are:

[0033] 1. When the conveyor belt transports plastic flooring, it will not wear down the plastic flooring in the material rack 4, and the pressure of multiple stacked plastic floorings will not be applied to the conveyor belt, thus not increasing the driving force of the conveyor belt, making it highly practical.

[0034] 2. The feeding mechanism is linked with the conveyor belt mechanism, ensuring a stable and reliable feeding rhythm;

[0035] 3. The plastic flooring slides along the horizontal plate 11 and the guide plate 12 onto the conveyor belt 3, reducing the impact on the plastic flooring and the conveyor belt 3 and improving stability.

[0036] The plastic flooring film coating feeding mechanism of this utility model uses common mechanical methods for installation, connection, or setting. Any method that can achieve the beneficial effect can be implemented. The frame 1, roller 2, conveyor belt 3, material rack 4, slider 6, crossbar 7, push plate 8, roller 10, lead screw 13, lead screw nut 14, motor 15, contact switch 16, roller shaft 19, transmission belt 20, slide rail 22, slider 23, and tension spring 26 of this utility model are commercially available. Technical personnel in this industry only need to install and operate it according to the accompanying instruction manual, without requiring any creative work from those skilled in the art.
