Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of plastic plate bending, in particular to a bending machine for processing PP plastic plates. Background Technique
[0002] A PP plastic plate bending machine is a mechanical device specifically used for processing polypropylene (PP) plastic plates. This bending machine can directly bend plastic plates without splicing, grooving or using welding rods, thus ensuring a beautiful appearance of the folded angle and no water leakage. The bending machine usually adopts an overall heating method and is suitable for bending operations of various thermoplastic materials.
[0003] Common bending machines include a feeding mechanism, a pressing mechanism and a bending mechanism. When in use, the feeding mechanism is used to push the plate for movement, and then the pressing mechanism is used to heat and press the plate, so that a crease is pressed on the surface of the plate. Finally, the turning of the bending plate is driven by a cylinder, so that the PP plastic plate can be bent along the crease.
[0004] However, in this way, since the PP plastic plate is only fixed by pressing at the crease during bending, and the tail of the PP plastic plate lacks a limiting mechanism, the instability of the PP plastic plate is increased during bending, and further the risk of plate movement or deviation is increased, resulting in inaccurate bending angles or uneven bending of the PP plastic plate, which cannot meet the working requirements of the bending machine. Therefore, a bending machine for processing PP plastic plates is proposed. Content of the Utility Model
[0005] (I) Technical Problems to be Solved
[0006] Aiming at the deficiencies of the prior art, the utility model provides a bending machine for processing PP plastic plates to solve the technical problem that during bending, the PP plastic plate is only fixed by pressing at the crease, and the tail of the PP plastic plate lacks a limiting mechanism, resulting in plate movement or deviation during bending.

The right end of the guide rod is connected to a mounting table, and the third cylinders are mounted on the left and right sides of the top of the mounting table through bearings.

[0014] Preferably, the bottom of the feeding mechanism is connected to the left side of the bending table through a telescopic rod. The top end of the third cylinder is connected to the corresponding position at the bottom of the folding plate through a hinge seat, avoiding interference.
[0015] Preferably, a motor is inserted into the right side inside the bending table. The rotor of the motor is coaxially connected to a lead screw.

[0017] (III) Advantageous Effects
[0018] Compared with the prior art, the present utility model provides a bending machine for processing PP plastic plates, having the following advantageous effects:
[0019] For this bending machine for processing PP plastic plates, the telescopic movement of the second cylinder drives the up-and-down swing of the transmission arm. Thus, with the cooperation of the limiting plate, the pressure plate can be changed from a vertical state to a horizontal state and pressed on the surface of the plate. When bending the front end of the plate, the pressure plate can tightly limit the tail of the plate, thereby reducing the problems of inaccurate bending angles or non-straight bending caused by the movement of the plate. Moreover, through the additional support provided to the tail of the plate, it helps to improve the stability of the entire bending process, which is particularly important when processing long or thick plates. At the same time, due to the auxiliary limiting effect of the pressure plate, the bending edge of the PP plastic plate will be more neat, improving the processing quality of the bending machine.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0026] The present utility model provides a technical solution, a bending machine for processing PP plastic plates, including a bending table 1, a first cylinder 2, a hot pressing table 3, a feeding mechanism 4, a mounting seat 5, a second cylinder 6, a transmission arm 7, a connecting arm 8, a pressing plate 9, a spring 10, a limiting plate 11, a guide rod 12, a mounting table 13, an articulated rod 14, a folding plate 15, a third cylinder 16, a motor 17, a lead screw 18 and a limiting disc 19:
[0027] Please refer to Figure 1 , both the front and rear ends on the left side of the bending table 1 are provided with first cylinders 2, the tops of the first cylinders 2 are both provided with hot pressing tables 3, and a feeding mechanism 4 is provided on the left side of the bending table 1;
[0028] The mounting seat 5 is provided on the left and right sides of the top of the hot pressing table 3. Please refer to Figure 2 , the upper left part of the mounting seat 5 is hinged with a second cylinder 6 through a bearing, and the lower left part of the mounting seat 5 is hinged with a transmission arm 7 through a bearing;
[0029] The connecting arm 8 is installed at the left end of the transmission arm 7. The left end of the second cylinder 6 is inserted into the inside of the connecting arm 8 through a bearing. The lower left part of the connecting arm 8 is hinged with a pressing plate 9, and the middle position at the bottom of the second cylinder 6 is connected with a limiting plate 11;
[0030] Please refer to Figure 3 As shown in the figure, the guide rod 12 is inserted on the left and right sides of the lower part of the right end of the bending table 1. The hinge rods 14 are inserted on the left and right sides of the upper part of the right end of the bending table 1. The turning plate 15 is inserted through bearings on the inner sides of the hinge rods 14. The right end of the guide rod 12 is connected to the mounting table 13. Both left and right sides of the top of the mounting table 13 are installed with the third cylinders 16 through bearings. Please refer to Figure 2 As shown in the figure, springs 10 are installed on the left side of the upper surface of the pressure plate 9 and the lower part of the connecting arm 8. The limiting plate 11 is arranged in a U shape. The bottom of the feeding mechanism 4 is connected to the left side of the bending table 1 through a telescopic rod. The top end of the third cylinder 16 is connected to the corresponding position at the bottom of the turning plate 15 through a hinge seat. By the telescopic movement of the second cylinder 6, the up-and-down swing of the transmission arm 7 is driven. Thus, with the cooperation of the limiting plate 11, the pressure plate 9 can be changed from the vertical state to the horizontal state and pressed on the surface of the plate. When the front end of the plate is bent, the tail of the plate can be tightly limited by the pressure plate 9. Furthermore, the problem of inaccurate bending angle or non-straight bending caused by the movement of the plate can be reduced. And with the additional support provided to the tail of the plate, it helps to improve the stability of the entire bending process, especially more important when processing long or thick plates. At the same time, due to the auxiliary limiting effect of the pressure plate 9, the bending edge of the PP plastic plate will be neater, improving the processing quality of the bending machine;
[0031] Please refer to Figure 4 As shown in the figure, a motor 17 is inserted into the right side inside the bending table 1. Please refer to Figure 3 The rotor of the motor 17 is coaxially connected to a lead screw 18. The right end of the lead screw 18 penetrates through the corresponding position inside the mounting table 13. A limiting disk 19 is coaxially installed at the front end of the lead screw 18. The lengths of the guide rod 12 and the hinge rod 14 are the same, and the lengths of the guide rod 12 and the hinge rod 14 are both greater than that of the lead screw 18. The rotation of the lead screw 18 can be driven by the motor 17. Thus, the distance between the mounting table 13, the third cylinder 16 and the turning plate 15 and the bending table 1 can be adjusted. This not only improves the torque during turning, but also facilitates the use of plates of different sizes.
[0032] This solution drives the up-and-down swing of the transmission arm 7 through the telescoping of the second cylinder 6, so that the pressure plate 9 can be changed from the vertical state to the horizontal state and pressed on the surface of the plate with the cooperation of the limit plate 11. When bending the front end of the plate, the tail of the plate can be tightly limited by the pressure plate 9, thereby reducing the problems of inaccurate bending angle or uneven bending caused by the movement of the plate. Moreover, the additional support provided for the tail of the plate helps to improve the stability of the entire bending process, especially important when dealing with longer or thicker plates. At the same time, due to the auxiliary limiting effect of the pressure plate 9, the bending edge of the PP plastic plate will be more neat, improving the processing quality of the bending machine. At the same time, the rotation of the lead screw 18 can be driven by the motor 17, so as to adjust the distance between the installation table 13, the third cylinder 16 and the folding plate 15 and the bending table 1, which not only increases the torque during folding, but also facilitates the use of plates of different sizes.
