Description

Technical Field

[0001] The utility model relates to the technical field of slotting devices, in particular to a double-sided slotting device for a PET plate. Background Art

[0002] PET board is a highly functional and widely used plastic material. After being planed on both sides by a double-sided planer, grooves with a certain spacing need to be cut before the board can be transferred to the next step for further processing.

[0003] In the prior art, a double-sided peeling and grooving integrated machine (Announcement No.: CN207373364U) clamps the plate through the telescopic plates on both sides under the action of springs. When one end of the plate is transported to the traction frame, the other end of the plate is pushed by the raised strips to keep the plate vertical and move into the traction frame, thus avoiding the problem of tilted peeling and grooving caused by the tilt of the plate when placed manually. However, the device does not have sufficient limit on the longitudinal displacement of the plate during the grooving process. The vibration generated during the grooving process can easily cause the plate to shake, resulting in uneven groove depths, thereby reducing the processing quality of the plate.

[0027] Reference Figure 1-Figure 7A double-sided grooving device for PET sheets comprises an equipment frame 1, wherein two conveying mechanisms are symmetrically installed in the equipment frame 1, and a plurality of first clamping mechanisms 9 are provided on the surface of each conveying mechanism at equal intervals. Two saw shafts 12 are rotatably installed between two opposite sides of the equipment frame 1, and two second clamping mechanisms 11 are symmetrically provided on both sides of the saw shaft 12. Each second clamping mechanism 11 comprises two support boxes 1101 and two second clamping blocks 1103. A connecting rod 1102 is fixedly installed at both ends of each second clamping block 1103. A slider 1105 is fixedly mounted on one end of the rod 1102 away from the second clamping block 1103. Multiple sliders 1105 are slidably mounted in corresponding support boxes 1101. The two support boxes 1101 are symmetrically fixedly mounted on both sides of the equipment frame 1. A bidirectional screw rod 1104 is rotatably mounted in each support box 1101. The two ends of each bidirectional screw rod 1104 pass through the outer surfaces of the two sliders 1105 and are threadedly connected thereto. A fine-tuning mechanism for driving the bidirectional screw rod 1104 is provided below each second clamping mechanism 11. The present utility model, by providing a first clamping mechanism 9 and a second clamping mechanism 11 to cooperate with each other, limits the two sides and upper and lower surfaces of the PET sheet when the PET sheet passes between the two saw shafts 12 along the conveying mechanism, thereby preventing the PET sheet from vibrating and deviating during the slotting process, which would affect the accuracy of the slotting, thereby improving the quality of the PET sheet processing.

[0028] In this embodiment, the fine-tuning mechanism includes two worm gears 19, two worms 18 and two support columns 17. The two support columns 17 are symmetrically fixed on both sides of the equipment frame 1, and the two worm gears 19 are symmetrically rotatably installed on both sides of the equipment frame 1. The top rotation center of each worm gear 19 is fixed to the bottom end of the corresponding bidirectional screw 1104 through a connecting shaft.

A convex rafter adapted to the limiting groove is provided in the limiting hole 20, and the other end of the adjusting screw 16 is slidably embedded in the limiting hole 20.

[0029] When in use, the second clamping block 1103 is made of rubber material, and each of the second clamping blocks 1103 has a chamfered bottom near the incoming material side to facilitate the plate to enter better between the two second clamping blocks 1103. The second clamping mechanism 11 is provided with two and is located on both sides of the saw shaft 12, which can simultaneously limit the two ends of the plate to avoid the plate warping caused by force at the slot, thereby improving the quality of equipment processing. Each second clamping mechanism 11 can drive the two worms 18 to rotate by rotating the handwheel 15 in the fine-tuning mechanism. The two worms 18 simultaneously drive the two worm gears 19 to rotate synchronously in the same direction, and the two worm gears 19 simultaneously drive the two bidirectional screw rods 1104 to rotate. Each bidirectional screw rod 1104 simultaneously drives the two sliders 1105 located in the same support box 1101 to slide toward each other, thereby controlling the distance between the two second clamping blocks 1103, so that it can limit plates of different thicknesses, thereby improving the applicability of the equipment.

[0030] In this embodiment, the transmission mechanism includes a driven transmission roller 2, a conveyor belt 3 and an active transmission roller 4. The driven transmission roller 2 and the active transmission roller 4 are both rotatably installed on the same side of the equipment frame 1. The conveyor belt 3 is sleeved between the driven transmission roller 2 and the active transmission roller 4. A transmission main shaft is provided between the two transmission mechanisms. The two ends of the transmission main shaft are fixedly installed with the rotation centers of the two active transmission rollers 4 respectively. A driving pulley 6 and a driven pulley 5 are rotatably installed on one side of the equipment frame 1. A belt 7 is sleeved between the driven pulley 5 and the driving pulley 6. A first motor 8 is fixedly installed in the equipment frame 1. The output end of the first motor 8 passes through one side of the equipment frame 1 and is fixedly installed on the rotation center of the active pulley 6. The first clamping mechanism 9 includes a fixed block 901. The fixed block 901 is fixedly installed on the surface of the conveyor belt 3. A sliding shaft 902 with a shoulder column structure is slidably installed in the fixed block 901. The sliding shaft 902 is close to the equipment A first clamping block 903 is fixedly installed at one end in the middle of the frame 1, and a return spring 904 is sleeved on the surface of the other end of the sliding shaft 902. The two ends of the return spring 904 are respectively fixed to the shoulder of the sliding shaft 902 and one side of the fixed block 901. Two push plates 10 are symmetrically slidably installed on the top of the equipment frame 1. A fastening bolt 22 is threadedly connected to one side of each push plate 10, and the bottom end of each fastening bolt 22 is against the top of the equipment frame 1. The top of the equipment frame 1 is symmetrically provided with scale lines 21 for displaying the position of the push plates 10. Two pads 13 for supporting the plate are symmetrically fixedly installed at both ends of the top of the equipment frame 1. A gear 23 is fixedly installed on the same end of the two saw shafts 12, and the two gears 23 are meshed with each other. A second motor 14 is fixedly installed on the side of the equipment frame 1 away from the gear 23, and the output end of the second motor 14 is connected to the rotation center of one of the saw shafts 12 through a coupling.

[0031] During use, two push plates 10 are slidably installed on the top of the equipment frame 1. When the first clamping mechanism 9 passes between the two push plates 10, the sliding shaft 902 in the first clamping mechanism 9 slides toward the side of the plate under the squeezing action of the push plates 10, thereby driving the first clamping block 903 to press against the side of the plate. At this time, the reset spring 904 is compressed. After the plate is grooved and reaches one end of the equipment with the conveyor belt 3, the first clamping mechanism 9 disengages from the limit of the push plate 10. Under the reset force of the reset spring 904, the sliding shaft 902 resets, loosens the limit on the side of the plate, and thus the plate can be automatically released from the restriction to facilitate unloading. The position of the push plate 10 is adjusted by the scale line 21 on the top of the equipment frame 1, and the first clamping mechanism 9 can be controlled to clamp plates of different widths, thereby improving the practicality of the equipment.

[0032] From the above description, it can be seen that the above-mentioned embodiments of the present invention achieve the following technical effects: the plate to be grooved is placed in the middle of the top of the pad 13 at the feed end of the equipment, and then the plate is pushed in the feeding direction until the first clamping mechanism 9 clamps both sides of the plate, and then the plate is brought between the two saw shafts 12 along the driving direction of the conveyor belt 3. Saw shafts 12 of appropriate diameter are selected according to the requirements of grooves. When the plate passes through the second clamping mechanism 11 before grooves, under the upper and lower clamping effect of the two second clamping blocks 1103 in the second clamping mechanism 11, the plate is always in a stable conveying state, which facilitates more precise grooves and improves the processing quality of the plate.

[0033] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
