An electric eye is installed to control the automatic start and stop of the truncating cylinder to control automatic blank cutting and feeding, reducing the labor intensity of employees and improving the output rate. The design of the mounting plate facilitates the installation of the electric eye. This automatic blank cutting and feeding device for the bottle blowing system is reasonably designed and easy to use, and can timely cut the blank. However, when the truncating cylinder fails, bolts need to be taken out one by one to disassemble and repair it, and the disassembly and repair are relatively cumbersome, increasing the workload of the operator and reducing the working efficiency of the device. During the transportation of the bottle blanks by the conveyor belt, they are prone to falling due to external interference, resulting in damage to the bottle blanks and reducing the safety of the device. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problems that when the truncating cylinder fails, bolts need to be taken out one by one to disassemble and repair it, the disassembly and repair are relatively cumbersome, increasing the workload of the operator and reducing the working efficiency of the device, and during the transportation of the bottle blanks by the air conveyor line, they are prone to falling due to external interference, resulting in damage to the bottle blanks and reducing the safety of the device, and to propose an automatic blank cutting and feeding device for a bottle blowing system.

[0005] To achieve the above purpose, the utility model provides the following technical solution:

[0006] Design an automatic blank cutting and feeding device for a bottle blowing system, including a base and a conveyor belt. The conveyor belt is installed at the upper end of the base, and an auxiliary protection device is provided at the lower end of the base. A bottle blowing machine is arranged outside the conveyor belt, and an auxiliary disassembly device is provided outside the right end of the base. A truncating cylinder is arranged outside the auxiliary disassembly device.

[0007] Preferably, the auxiliary protection device includes a first motor and a first housing. The upper end of the first housing is fixedly connected to the base. The first motor is fixedly connected to the first housing through a bracket and bolts. A first worm is fixedly connected to the output shaft of the first motor. The outer wall of the first worm meshes with a first worm gear. A rotating rod is fixedly connected to the rotating shaft of the first worm gear. On both sides of the upper end of the rotating rod, bumps are fixedly connected. The outer wall of the bump is slidably connected to the baffle.

[0008] Preferably, both ends of the first worm are rotatably connected to the first housing through bearings. The rotating shaft of the first worm gear is rotatably connected to the first housing through a bearing. The outer wall of the baffle is slidably connected to the first housing.

[0009] Preferably, support legs are fixedly connected to the lower end of the base.

[0012] For the automatic blank cutting and feeding device of a bottle blowing system proposed by the present utility model, the beneficial effects are as follows: Through the cooperation of the auxiliary protection device and the conveyor belt, when the output shaft of the first motor is started to rotate, it drives the first worm to rotate. The rotation of the first worm drives the first worm gear to rotate. While the first worm gear rotates, it drives the rotating rod to rotate. The rotation of the rotating rod drives the bump to move. While the bump moves, it drives the baffle to move inward. After the baffle moves to a suitable position, it prevents the conveyor belt from being interfered by external forces during the transportation of the bottle preforms, resulting in the dropping and damage of the bottle preforms, and improves the safety of the work.

[0013] Through the cooperation of the auxiliary disassembly device and the cutting cylinder, when the cutting cylinder fails and needs to be disassembled and repaired, the output shaft of the second motor is started to rotate to drive the second worm to rotate.

[0027] Refer to the attached Figure 1 、 2 Figures 4, 7 and 8: The auxiliary disassembly device 3 includes a second motor 301 and a second housing 302. The second motor 301 can meet the working requirements according to actual needs. The outer wall of the second housing 302 is fixedly connected to the base 1.

[0028] Working principle:

[0029] Move the device to dock the conveyor belt 4 with the air delivery line of the labeling machine.

[0030] The process of auxiliary protection for the conveyor belt:

[0031] Connect the external power supply of the first motor 201 to start the rotation of the output shaft of the first motor 201, which drives the rotation of the first worm 203. The rotation of the first worm 203 drives the rotation of the first worm gear 204. While the first worm gear 204 is rotating, it drives the rotation of the rotating rod 205. The rotation of the rotating rod 205 drives the movement of the convex block 206. While the convex block 206 is moving, it drives the baffle 207 to move inward. After the baffle 207 moves to a suitable position, it stops, completing the auxiliary protection process of the conveyor belt, avoiding external interference during the transportation of the preforms by the conveyor belt 4, which may cause the preforms to fall, and preparing for the subsequent transportation of the preforms.

[0032] The process of breaking preforms during the transportation of preforms:

[0033] After the preforms come out of the bottle unscrambler, they fall on the surface of the conveyor belt 4. Connect the external power supply of the power device of the conveyor belt 4 to start the movement of the conveyor belt 4, which drives the preforms into the interior of the blow molding machine 5. The operator sends the preforms into the interior of the blow molding machine 5 for blow molding. The preforms after blow molding are then transported by the conveyor belt 4 to the surface of the air conveyor line of the labeling machine, preparing for the subsequent work. When the labeling machine malfunctions, stop the work of the conveyor belt 4, and at the same time control the telescopic end of the cutting cylinder 6 to extend, blocking the transportation of the preforms and breaking the preforms to avoid losses. When the labeling machine is repaired, control the telescopic end of the cutting cylinder 6 to retract, and start the work of the conveyor belt 4 again, preparing for the subsequent work.

[0034] The auxiliary disassembly process of the cutting cylinder:

[0035] When the cutting cylinder 6 malfunctions and needs to be disassembled and repaired, connect the external power supply of the second motor 301 to start the rotation of the output shaft of the second motor 301, which drives the rotation of the second worm 303. The rotation of the second worm 303 drives the rotation of the second worm gear 304. The rotation of the second worm gear 304 drives the rotation of the double-headed stud 305. The rotation of the double-headed stud 305 drives the clamping plates 306 on both sides to move outward, so that the clamping plates 306 no longer tightly fix the cutting cylinder 6. The operator can take out the cutting cylinder 6 for repair. After the repair is completed, control the above process and operate in the reverse direction, making the disassembly of the cutting cylinder 6 more convenient.
