Description

Technical Field

[0001] This utility model relates to the field of quality inspection technology for plastic bottle processing equipment, and more specifically, to a levelness detection mechanism for plastic bottle blow molding molds. Background Technology

[0002] During the plastic bottle processing, the preform is transported upside down through the mold head to the position between the two blow molding molds on both sides of the blow molding machine. After the blow molding molds on both sides close inward, the preform inside the mold is blow molded through the blow molding pipeline. The blow molding molds on both sides need to maintain a uniform level to ensure the blow molding quality of the preform in the middle. If there is vertical misalignment, it will cause the blow-molded plastic bottle to deform.

[0003] Existing blow molding machines are not designed with corresponding blow molding mold level detection equipment. As a result, when the blow molding mold becomes misaligned after long-term use, it is difficult to detect and repair it in time, which affects the blow molding quality of plastic bottles. Utility Model Content

[0004] The purpose of this invention is to provide a levelness detection mechanism for plastic bottle blow molding molds. This mechanism can detect the levelness of the clamping seat and the mold in real time. It uses a positioning laser to detect the levelness through a light-transmitting hole, which has high accuracy and can quickly detect vertical misalignment of the mold, reminding staff to carry out timely repairs.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A plastic bottle blow molding die leveling detection mechanism includes a blow molding machine frame, a top support on the top of the blow molding machine frame, and a telescopic cylinder on the inner side of the blow molding machine frame. The telescopic cylinder is connected inward to a clamping seat. A die is connected to the inner side of the clamping seat via adjusting bolts around its perimeter. A conveyor chain passes under the die, and bottle preforms are inverted above the conveyor chain via several equally spaced die heads. The bottle preforms are blow molded through the die to obtain a plastic bottle. Convex detection bases are provided at both the front and rear ends of the clamping seat and the die. The lower surface of the detection base is in contact with the upper surface of the clamping seat and the die, respectively. Vertical support plates are connected upward to the left and right ends of the upper surface of the detection base. Light-transmitting holes of the same height are machined at corresponding positions on the sides of the vertical support plates, and the upper ends of the vertical support plates are connected to horizontal support plates. A through hole is opened at the center of the horizontal support plate, and a sleeve seat passes through the through hole. A compression spring is fitted onto the cylinder between the upper end of the sleeve seat and the horizontal support plate. A connecting rod is connected above the sleeve seat.

[0007] As a further optimization of this solution, the upper end of the connecting rod is threaded and fixed to the horizontal section of the L-shaped connecting rod by a nut. The inner end of the horizontal section of the L-shaped connecting rod is connected to a levelness detection laser emitter and a levelness detection laser receiver through a vertical telescopic connecting rod. The levelness detection laser emitter emits a positioning laser through a laser head, which passes through all the light-transmitting holes and is received by the levelness detection laser receiver.

[0008] As a further optimization of this solution, the upper end of the vertical section of the L-shaped connecting rod is connected to the connecting bar, and the connecting bar is fixedly connected to the lower surface of the top support by bolts. A control box is fixed to the lower surface of one side of the connecting bar, and the control box is connected to the level detection laser emitter, the level detection laser receiver and the power supply through wiring.

[0009] As a further optimization of this solution, the length of the vertical support plate above the clamping seat is less than the length of the vertical support plate above the mold.

[0010] As a further optimization of this solution, when the clamping seat and the mold are misaligned, the position of the light-transmitting hole moves up or down to block the path of the positioning laser.

[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows:

[0012] This invention incorporates vertical and horizontal support plates, as well as a levelness detection laser emitter and receiver, designed on the existing left and right side clamping seats and above the mold. This allows for real-time detection of the levelness of the clamping seats and mold. The levelness is detected by passing a positioning laser through a light-transmitting hole, resulting in high accuracy and the ability to quickly detect vertical misalignment of the mold, prompting workers to perform timely repairs.

Detailed Implementation

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0019] To address the issue that existing blow molding machines lack corresponding mold level detection equipment, which makes it difficult to detect and repair mold misalignment after long-term use, thus affecting the blow molding quality of plastic bottles;

[0020] like Figure 1 As shown, this application includes a blown film machine frame 1, a top support 2 is provided above the blown film machine frame 1, and a telescopic cylinder 3 is provided on the inner side of the blown film machine frame 1. The telescopic cylinder 3 is connected to a clamping seat 4 inward. A mold 5 is connected to the inner side of the clamping seat 4 through adjusting bolts 10 around the perimeter. A conveyor chain 6 passes through the bottom of the mold 5. A bottle preform 8 is inverted and loaded above the conveyor chain 6 through several equally spaced mold heads 7. The bottle preform 8 is blown by the mold 5 to obtain a plastic bottle 9.

[0021] like Figure 2 and Figure 3 As shown, both the front and rear ends of the clamping seat 4 and the mold 5 are provided with convex detection bases 11. The lower surface of the detection base 11 is in contact with the upper surface of the clamping seat 4 and the mold 5 respectively. The left and right ends of the upper surface of the detection base 11 are connected to vertical support plates 12. The corresponding positions on the side of the vertical support plate 12 are all machined with light-transmitting holes 21 of the same height. The upper end of the vertical support plate 12 is connected to the horizontal support plate 20. A through hole is opened at the center of the horizontal support plate 20 and the sleeve seat 18 passes through the through hole. A compression spring 19 is installed on the cylinder between the upper end of the sleeve seat 18 and the horizontal support plate 20. A connecting rod 13 is connected above the sleeve seat 18.

[0022] The upper end of the connecting rod 13 is threaded and fixed to the horizontal section of the L-shaped connecting rod 14 by a nut. The inner end of the horizontal section of the L-shaped connecting rod 14 is connected to a level detection laser emitter 16 and a level detection laser receiver 17 via a vertical telescopic connecting rod 15. The level detection laser emitter 16 emits a positioning laser through the laser head, which passes through all the light-transmitting holes 21 and is received by the level detection laser receiver 17.

[0023] like Figure 4 As shown, the upper end of the vertical section of the L-shaped connecting rod 14 is connected to the connecting bar 22. The connecting bar 22 is fixedly connected to the lower surface of the top support 2 by bolts. A control box 23 is fixed to the lower surface of the connecting bar 22 on one side. The control box 23 is connected to the level detection laser emitter 16, the level detection laser receiver 17 and the power supply through wiring.

[0024] Specifically, the length of the vertical support plate 12 above the clamping seat 4 is less than the length of the vertical support plate 12 above the mold 5. The lower surface of the detection base 11 on both sides is made to fit and contact the upper surface of the clamping seat 4 and the mold 5 respectively by the downward pressure spring 19. The appropriate diameter of the light-transmitting hole 21 can be processed according to the size range of the horizontality requirement. Under normal circumstances, the positioning laser emitted by the horizontality detection laser emitter 16 passes through all the light-transmitting holes 21 and is received by the horizontality detection laser receiver 17. The control box 23 receives the laser signal. At this time, the horizontality of the molds 5 on both sides meets the processing requirements. When the clamping seat 4 and the mold 5 are misaligned, the position of the light-transmitting hole 21 on the vertical support plate 12 moves up or down, which will block the path of the positioning laser, so that the horizontality detection laser receiver 17 cannot receive the laser signal completely. At this time, the control box 23 can send the fault information to the maintenance personnel. The maintenance personnel can adjust the horizontality of the molds 5 on both sides by tightening or loosening the adjusting bolts 10 around the clamping seat 4 according to the on-site situation, so that the horizontality detection laser receiver 17 receives the complete laser signal and realizes real-time detection operation.
