Description

Technical Field

[0001] The utility model belongs to the field of bottle embryo conveying equipment, and in particular relates to a bottle embryo conveying device. Background Art

[0002] Preform conveyor belt is a kind of equipment used in bottle production line. Its main function is to transfer preform from one workbench to another workbench or to the equipment of the next process. Through the automatic operation of conveyor belt, production efficiency can be improved, manual operation can be reduced, and the consistency of product quality can be ensured. Preform conveyor belt plays an important role in the bottle production process and is one of the indispensable important equipment of modern production line.

[0003] The preform conveying device usually includes components such as conveyor belts, transmission devices, guide devices and control systems. The conveyor belt is usually made of special materials and designs to ensure that the preforms are not damaged or deformed during transportation. The transmission device provides power to drive the conveyor belt. The guide device is used to guide the preforms along the set path to avoid deviation or blockage.

[0004] In the prior art, the preform conveying system uses the height difference to make the preform move along the track under the influence of its own gravity, or pushes the preform in front to move by the subsequent preforms continuously entering the track, or clamps individual preforms through a conveyor belt by a specific clamp. However, these solutions have some problems, such as requiring a specific construction method, being unable to move autonomously without the push of subsequent preforms, and low transmission efficiency.

[0005] Therefore, a new solution is needed that can actively transport the preforms and has higher transport efficiency. Utility Model Content

[0006] In view of the above problems existing in the prior art, the purpose of the utility model is to provide a preform conveying device.

[0007] In order to solve the above problems, the technical solution adopted by the utility model is as follows:

[0008] A preform conveying device comprises a conveying track and a conveying belt, wherein the conveying belt is arranged inside the conveying track, and traction motors connected to the conveying belt are arranged at the front and rear ends of the conveying track, and two conveying belts are arranged symmetrically on the left and right sides of the conveying track, and a preform conveying groove is provided between the two conveying belts.

[0009] The conveyor belt is an up-and-down rotating structure in the conveyor track. The conveyor belt located in the upper half of the conveyor track is the conveying part, and the conveyor belt located in the lower half of the conveyor track is the rotating part.

[0010] The width of the preform conveying groove is smaller than the diameter of the preform.

[0011] The conveyor belt is a soft belt.

[0012] The conveyor belt is a T-belt.

[0013] A pressure wheel is arranged above the T-belt of the conveying part, and a supporting wheel is arranged below the T-belt.

[0014] A pressure wheel is arranged above the T-belt of the rotating part, and a supporting wheel is arranged below the T-belt.

[0015] The conveying belt is provided with structures turned outwards toward both sides of the preform conveying groove at the openings at both ends of the conveying track.

[0016] The width of the outward-turned structure of the conveyor belt is larger than the diameter of the bottle preform and smaller than the diameter of the bottle mouth ring of the bottle preform.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] The utility model uses symmetrically arranged belts to transport the preforms, clamping the preforms between two belts for traction and transportation. In this way, the transportation of the preforms is no longer restricted by the installation height of the equipment, and can be directly transported from a low place to a high place. During the transportation process, the preforms can be more firmly fixed on the conveying track, and there will be no accumulation and blockage. Compared with the clamp-type preform conveying device, the conveying belt of this solution can convey more preforms at the same time, and the conveying efficiency is higher.

[0022] The utility model is further described below in conjunction with specific embodiments.

[0023] like Figure 1 and Figure 2 As shown, the main body of the utility model is a conveying track 5 for conveying bottle preforms.

[0024] A traction motor 6 connected to the conveying belt 2 inside the conveying track 5 is arranged at the front and rear sections of the conveying track 5 , and the traction motor 6 drives the conveying belt 2 to transport the preform 1 .

[0025] There are two conveyor belts 2 and they are symmetrically arranged on both sides of the conveyor track 5. The gap between the two conveyor belts 2 is the preform conveying groove for clamping the preform 1. Its working state is as follows: Figure 2 shown.

[0026] The structure of the conveyor belt 2 in the conveyor track 5 is an up-and-down rotating structure. The upper half of the conveyor belt 2 contacts the preform 1 and is the conveying part of the conveyor belt 2 . The lower half of the conveyor belt 2 rotates and circulates inside the conveyor track 5 and is the rotating part of the conveyor belt 2 .

[0027] Compared with the annular conveying structure in which a single preform 1 is clamped by a clamp, this structure has a smaller overall volume, especially a volume in the lateral direction, and can better reduce the deadweight of the long-distance conveyor belt.

[0028] And due to its layout, the part where the conveyor belt 2 contacts the material and plays a conveying role is also different from that of an ordinary conveyor belt. Compared with an ordinary conveyor belt that transmits objects through the upper surface, the conveyor belt 2 of this scheme clamps the material through the sides of two belts and realizes the conveying function.

[0029] Therefore, the conveyor belt 2 adopts a T-belt, such as Figure 2 As shown, the width of the T-belt is narrower, but the belt is thicker, and the contact area between the side wall of the conveyor belt 2 and the preform 1 is larger, which can provide better friction. At the same time, because the width of the preform conveying groove formed by the two conveyor belts 2 has a high precision requirement, if the conveyor belt 2 deviates during operation, the preform 1 may be damaged due to excessive internal squeezing of the conveyor belt 2, and if the conveyor belt 2 deviates too much to the outside, the preform 1 may fall directly from the preform conveying groove to the conveying track 5.

[0030] Therefore, another reason for using the T-belt is to prevent it from shifting to the left or right to a large extent. According to the protruding part below the T-belt, a pressure wheel 4 is arranged above the T-belt of the conveying part, and a supporting wheel 3 is arranged below, which can effectively correct the deviation of the T-belt during movement. The T-belt of the rotating part below the conveying track 5 is also provided with a pressure wheel 4 and a supporting wheel 3 structure to maintain the gap between the conveying part belt and the rotating part belt, and also prevent the T-belt from derailing during rotation.

[0031] When the preform 1 is being conveyed, the mouth ring of the preform 1 is located above the conveying belts 2 on both sides of the preform conveying groove, and the conveying belts 2 clamp the preform 1 below the mouth ring. In order to provide greater friction to the preform 1, the width of the preform conveying groove is slightly smaller than the diameter of the preform 1. At the same time, in order to prevent the conveying belt 2 from squeezing the preform 1, the T-shaped conveying belt 2 adopts a soft belt with a certain elasticity.

[0032] The two ends of the conveyor track 5 are the input and output ports of the preform 1. In order for the preform 1 to smoothly enter the preform conveyor slot and exit from the preform conveyor slot, the conveyor belts 2 at the two ends of the conveyor track 5 are slightly turned outward toward the left and right sides of the preform conveyor slot. The width of the turned outward structure is greater than the diameter of the preform 1 but smaller than the diameter of the bottle mouth ring of the preform 1. This design can make the posture of the preform 1 uniform when entering the preform conveyor slot. When each preform 1 enters the preform conveyor slot, it will be in a posture where the bottle mouth ring rests on the conveyor belts 2 on both sides of the preform conveyor slot. At the exit, the conveyor belt 2 will no longer clamp the preform 1. The preform 1 can be smoothly output under the push of the rear preform 1, and will not be clamped by the conveyor belt 2 all the time so as to be turned over at the end with the conveyor belt 2.

[0033] The solution of the utility model provides a new method for conveying the bottle preform 1, which drives the movement of the bottle preform 1 by clamping the conveying belt 2. The overall structure is simple and easy to operate. It can realize the direct conveying of the bottle preform 1 from a low place to a high place while also ensuring the conveying efficiency of the bottle preform 1.
