Description

Technical Field

[0001] The utility model belongs to the field of bottle blowing production equipment and the field of bottle embryo production line arrangement and transportation, and specifically relates to a bottle embryo arrangement device. Background Art

[0002] The preform sorting machine is a supporting equipment of the two-step bottle blowing machine, also known as the preform aligning machine. Its main function is to sort the produced preforms, arrange them in a row and enter the preform conveying track, and then enter the equipment for the next bottle blowing process in sequence.

[0003] The two-step bottle blowing machine is a very mature process. The current subsequent production equipment structure is relatively fixed and difficult to improve. The overall material movement trajectory for bottle blowing production is to move diagonally downward from a high place, and various processes are carried out at the same time. Therefore, the conveying track for bottle preform conveying can only be set up very high at the beginning.

[0004] Therefore, in order to adapt to the subsequent production equipment, the bottle blank sorting machine in the prior art is designed accordingly. The hopper for feeding the material is set at a lower position, which is suitable for the staff to feed the material. At the back of the hopper, a hoist is needed to transport the bottle blanks to a high place, and then the bottle blanks transported to the high place are sent to the downward inclined blank sorting machine for sorting, and finally output to the conveying track set up at a high place.

[0005] Therefore, the preform arranging machine in the prior art is very bulky as a whole. The preforms in the hopper need to be transported to a high point before being sorted. The whole set of equipment occupies a large area, and there are many processes for transporting and sorting the preforms. During maintenance, it is necessary to take into account the inspection and maintenance of multiple devices.

[0006] Therefore, a new design is needed that is smaller in size and can still transport the preforms to a higher conveyor track. Utility Model Content

[0007] In view of the above problems existing in the prior art, the purpose of the utility model is to provide a preform arrangement device.

[0008] In order to solve the above problems, the technical solution adopted by the utility model is as follows:

[0009] A preform arrangement device comprises a hopper and a conveyor belt. The hopper is a long strip hopper that converges toward the center. A material trough is arranged at the center of the hopper. The conveyor belt is arranged on the inner side wall of the material trough. The hopper is provided with a preform disturbance device.

[0010] A plurality of blocking levers are arranged inside the hopper.

[0011] One end of the blocking lever is arranged on the inner wall of the hopper close to the material trough, and the other end is suspended in the air.

[0012] The suspended end of the blocking lever is arranged toward the feeding end of the hopper.

[0013] A cover plate is arranged above the hopper, and a feeding port is arranged at one end of the cover plate.

[0014] The preform agitation device is an air hole arranged on the inner wall of the hopper, and the air hole is connected to the air source component.

[0015] An outer frame is also arranged outside the hopper, the preform disturbance device is a vibration push rod arranged on the outer frame, the hopper is movably connected to the outer frame, and the two ends of the vibration push rod are respectively connected to the hopper and the outer frame.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] Compared with the prior art, the utility model has a simpler structure, and eliminates the hopper and lifter of the preform arranging equipment in the prior art. It is not necessary to lift the preforms in advance and then send them to the downward-sloping preform sorting machine for sorting. The utility model directly combines the lifting function with the preform sorting function. The staff directly pours the preforms into the hopper, and by disturbing the preforms in the hopper, the preforms can enter the material trough of the hopper in the correct posture, and then the preforms are transported by the conveyor belt on the inner wall of the material trough. This structure makes the entire preform sorting device occupy a smaller area, and is simpler to operate and maintain. At the same time, it is not necessary to set up the preform sorting equipment higher than the conveying track, which is also safer for the staff. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The utility model is further described below in conjunction with specific embodiments.

[0024] Example 1

[0025] like Figure 1 and Figure 2 As shown, the main body of the utility model is a hopper 1 for receiving and conveying bottle preforms.

[0026] The hopper 1 is in the shape of a long strip hopper with its left and right sides contracting toward the center. The center of the hopper 1 is an open structure, which is concave downward to form a material trough 2. The upper half of the material trough 2 is wider and the lower half is narrower, presenting a stepped structure with a larger upper part and a smaller lower part. Conveying belts 3 are arranged on the left and right sides of the lower half of the material trough 2. The cross section thereof is as shown in FIG. Figure 3 shown.

[0027] The structural design of the material trough 2 is designed according to the shape of the preform 4. When the preform 4 enters the material trough 2 in a correct posture, the bottle mouth is located in the upper half of the material trough 2, and the lower half of the preform 4 is located in the lower half of the material trough 2. The width of the upper half of the material trough 2 is slightly larger than the bottle mouth of the preform 4. When the conveyor belt 3 clamps the lower half of the preform 4 to move, the upper half of the material trough 2 will not hinder the movement of the preform 4.

[0028] A blocking lever 7 is also provided inside the hopper 1. The blocking lever 7 is provided on the hopper 1 on both sides of the material trough 2. One end of the blocking lever 7 is close to the material trough 2, and the other end is suspended in the hopper 1 near the edge of the hopper 1. The end close to the suspension is the end of the hopper 1 for feeding. Figure 1 and Figure 2 As shown, below the hopper 1 is a feeding port 6 for feeding the preforms 4, and the installation direction of the blocking lever 7 is as shown in the figure.

[0029] The main function of the blocking lever 7 is to block the preforms 4 that have not entered the material tank 2 in the correct posture but are entrained and raised. Since the preforms 4 are light in weight and the diameter of the bottle mouth is larger than the preforms 4 that have not been blown, it is easy for multiple preforms 4 to nest with each other and move up in a cluster. The blocking lever 7 blocks the preforms 4 that are nested with each other and makes them fall back to the bottom feeding end of the hopper 1 again. In order to better improve the blocking effect, the blocking lever 7 is staggered on both sides of the material tank 2.

[0030] In order to make the preforms 4 move in the hopper 1 and improve the probability of the preforms 4 falling into the material tank 2 in a correct posture, a device for disturbing the preforms is provided on the inner wall of the hopper 1. In this embodiment, the preform disturbing device is an air hole 8 provided on the inner wall of the hopper 1. The air hole 8 is connected to an external air source. When working, compressed air is introduced into the hopper 1 to blow up the accumulated preforms 4, so that the preforms 4 that have not entered the material tank 2 and remain on the inner wall of the hopper 1 are continuously moved, thereby improving the probability of the preforms 4 entering the material tank 2.

[0031] In order to prevent the preforms 4 from being over-pile up or being blown off the track by the air holes 8, a cover plate 5 is provided above the hopper 1. In order to facilitate feeding, a feeding port 6 is provided on the cover plate 5 at the bottom of the hopper 1, so that the staff can pour the preforms 4 to be sorted into the hopper 1.

[0032] Example 2

[0033] The structure of this embodiment is basically the same as that of the embodiment 1, except that the preform disturbance device does not use the air hole 8 for introducing compressed air, but a vibration push rod 9 is added to the outer frame of the supporting hopper 1. Figure 4 shown.

[0034] By extending and retracting the vibration push rod 9 , the hopper 1 as a whole can be shaken in a small or medium amplitude, and the accumulated preforms 4 can be driven to move inside the hopper 1 by the shaking of the hopper 1 as a whole.

[0035] The vibration push rod 9 in this embodiment is not limited to Figure 4 The design in the drawings of the specification is only provided to help understanding. If only the vibration push rod 9 is replaced with a structure of other types, but the function it achieves is still to help the preform 4 better enter the material trough 2 by shaking the hopper 1, it should also fall within the protection scope of this application.
