Description
Technical Field
The invention belongs to the technical field of auxiliary facilities of plastic hollow container blow molding machines, and particularly relates to a parison cold cutting and packaging device of a blow molding machine.
Background
As known in the art, in the process of forming a plastic hollow container by a plastic hollow container blow molding machine, a primary blow mechanism of the plastic hollow container molding machine first blows out a tubular preform, that is, the above-described parison, in a molten state, and the parison is introduced into a mold provided on a mold frame of an open-close mold mechanism and is blow-molded by a blow pin mechanism in a mold-closed state (referred to as secondary blow in the industry). Since the tubular preform is in the form of a continuous cylinder, it is cut once by a cold-cut wrapping device provided on the frame of the blow molding machine and corresponding to the lower part of the primary blowing mechanism, to ensure that the mold takes a quantity of tubular preform sufficient to form the desired plastic hollow container.
The prior art blank cutting device generally uses hot cutting, wherein the hot cutting is to cut by utilizing electric heating wires to electrify and heat, and the tubular blank cutting device with the structure has the following defects: firstly, the function is single, because the function of cutting off the tubular blank is only provided, and the function of sealing the cut part is not provided, thereby influencing the quality improvement of the product (the plastic hollow container, the following is the same), and the phenomenon of uneven wall thickness of the finally formed product is caused if the cut part is not sealed off for the flat product; secondly, the production efficiency of the plastic hollow container blow molding machine is affected, because the hot cutting does not have the sealing function, if the tubular material blank is required to be sealed according to the production process requirement, a set of sealing device is required to be independently added below a die, namely a forming die, so that the sealing time of the tubular material blank is prolonged, and the pre-blowing time of the tubular material blank is delayed; thirdly, energy is not saved, because the electric heating wire is used for heating the cutting knife and consuming electric energy, and the cutting knife is easy to wear a blank and is troublesome to replace; fourthly, raw materials are wasted because if the sealing means is separately provided under the mold, the length of the tubular preform is increased, i.e., lengthened, thereby causing unnecessary waste, i.e., waste of the tubular preform material to the extent that it extends out of the mold.
The parison cold cutting is capable of sealing the parison ready to descend from the primary inflation mechanism, and thus the above-described deficiency is made up, and the so-called cold cutting does not substantially heat the cutter of the parison cutting device, that is, cuts the parison by the normal temperature cutter.
Technical information about parison cold-cut encapsulation devices of blow molding machines is seen in the published chinese patent literature, typically "a cold-cut device" as recommended by document a.cn2014392907 u and "tubular parison cold-cut sealing device for plastic hollow container blow molding machines" provided by document b.cn20276191 u.
The structure and working principle of the above document a can be seen from paragraphs 0011 to 0012, and the structure and working principle of the above document B can be seen from paragraphs 0020 to 0028 and 0030. Each of the documents a and B can be redeemed for the technology described in the technical effects column of the specification, but has the same technical problems. In the case of document a, since a pair of holders (essentially a pair of gearboxes) are fixed to a holder, which is fixed to a connecting plate fixed to a frame of a blow molding machine, and racks for driving front and rear plates of a cutter respectively equipped with front and rear blades to be displaced toward each other or to be separated from each other are respectively in driving connection with the holders (i.e., gearboxes), the pair of holders (i.e., gearboxes) cannot be moved; in document B, the gear box is fixed to a fixing plate (corresponding to the fixing frame of document a), and the fixing plate is fixed to the frame of the blow molding machine, so that the gear box is likewise immovable. Under normal use condition, the static arrangement of the gear box can not generate interference influence on the maximum repulsive space of the two cutter frames, namely, the requirement that parisons enter the area between the two cutter frames and are cut off by the opposite movement of the two cutters can be met. However, since the positions of the two cutter holders on the blow molding machine correspond to the lower part of the inflation molding die head of the primary inflation mechanism, when the inflation molding die head is to be inspected, the hand of the inspection personnel usually goes from bottom to top to the space of the two cutter holders to perform operations such as cleaning or detaching the inflation molding die head above, and returns after the inspection is completed. In the foregoing process, since the two cutter holders are fixed with very sharp cutters (i.e., blades) in a facing state, and since it is subjectively desired that the larger and safer the space between the two cutter holders is, when performing the inspection operation on the inflation molding die head, to avoid the cutters from cutting the limbs, such as the arms, of the operator, but since the gear box cannot move, the degree of repulsion of the two cutter holders together with the cutters is limited, i.e., the desired repulsion requirement cannot be satisfied. Thus, the safety, the inspection efficiency and the inspection quality of the inspection worker are adversely affected. In view of the above, there is a need for improvements, and the technical solutions described below are created in this context.

The above-mentioned front screws 922 and 932 of the left and right moving plate fixing blocks are temporarily disconnected from the front ends of the left and right moving plate fixing blocks 92 and 93, respectively, by the inspector, and when the rear cutter frame 6 is manually moved backward, the case synchronous moving plate 9 is synchronously moved backward together with the pair of gear cases 8, that is, the pair of gear cases 8 are moved backward together with the case synchronous moving plate 9, until the rear cutter frame 6 is abutted against the left and right bearing blocks 12 and 13 of the fixing plate 1, so that the distance between the left and right cutter frames 5 and 6 is artificially increased to form a safe operation zone for the inspector to operate. After the completion of the inspection and protection of the inflation molding die head 30, the moving plate left fixed block front screw 922 is fixed to the front end of the moving plate left fixed block 92, and the moving plate right fixed block front screw 932 is fixed to the front end of the moving plate right fixed block 93.
In summary, the technical scheme provided by the invention overcomes the defects in the prior art, successfully completes the task of the invention, and faithfully honors the technical effects carried by the applicant in the technical effect column above.
