Description

Edge trimming device for plastic bottle blowing machine

The invention relates to a bottle cutting mouth mechanism of an automatic blow molding and blowing machine, which functions as a process flash or a process waste cutting edge which is left on the bottle mouth after blow molding, and belongs to an automatic blow molding and blowing machine. Auxiliary agency. Background technique

It is self-evident that the automatic blow molding machine can blow a variety of bottles efficiently. However, when blowing bottles such as jars, dairy bottles, etc., there are flash edges in the mouth of the bottle after the blow molding, which is used to be called waste edge and needs to be cut off. The traditional method of cutting the edge of the bottle is to use manual cutting. The problem is that the manpower is too much, the work efficiency is low, and the incision is not regular. The first thing is to use machine cutting, when the blow molding machine is blown. After the bottle is blown, it is transferred to a separate bottle-cutting machine to remove the flash. The efficiency and the regularity of the slit are better than the former, but the cutting machine is separated from the blow molding machine. Therefore, there is inevitably a transfer process, which also requires corresponding transfer manpower input, or a special operator is required to feed the bottles one by one to the bottle-cutting machine. Therefore, the manpower input and cutting efficiency are still Not satisfactory.

In the US Patent No. 3,868,824, a method and a device for blowing a hollow plastic container are disclosed, and the technical content of the burr which is left on the hollow container is also mainly mentioned, and the contents and drawings of the specification provided therein are known. The structure of the cutting edge device is composed of a strip blade cutting mechanism, a power rotary cutting mechanism, a hollow container clamping positioning mechanism, a hollow container conveying mechanism, and the like. The strip blade cutting mechanism includes a blade, a tool holder, a fixing plate, a guide sleeve, a guide post, a compressed air controller, etc. The power rotary cutting mechanism includes a frame, a stepping motor, a large sprocket, a chain, a small sprocket, a pair a large gear, a pin, a rotating shaft, a positioning pin, a roller, a disc cutter, etc.; the hollow container positioning mechanism includes an eccentric push rod, a roller, an arm, a pivot shaft, a cam, and the like; the hollow container conveying mechanism includes a conveyor belt and the like. Specifically, the stepping motor drives a pair of large sprocket wheels through a chain and a set of pinion gears disposed on the positioning fixed arms, and a set of positioning fixed arms are fixed on the rotating plate of the rotating frame, and the rotation is driven by the power through the transmission shaft. In the embodiment, the cutter shaft is disposed in the center hole of the sleeve of each fixed arm, the upper end is fixed with the pinion gear, and the lower end is fixed by the disc and the disc cutter, and the bottle mouth of the hollow container is rotated by the rotary cutter. In order to prevent the bottle mouth offset of the hollow container during cutting, it is clamped by a pair of positioning rollers, one of which is fixed at one end of the swing arm, the center hole of the swing arm is sleeved on the sleeve, and fixed to the positioning fixed arm The upper roller is used for clamping, and the clamping force of the swing arm is achieved by a fixed cam guide with a chute. In this way, the disc cutter rotates the cutter counterclockwise to drive the bottle mouth to rotate clockwise to complete the cutting. In Corresponding to the other side of the bottle mouth, a strip-shaped blade cutting mechanism composed of a guide post, a knife guide sleeve, a tool holder seat, a fixed plate and a strip blade is further arranged, and the guide sleeve fixing plate drives the knife under the pushing of the cylinder The pedestal is rotated at an angle to allow the blade to simultaneously squeeze the bottle opening. In addition, the bottles that need to be cut off are also transported by a special chain conveyor.

The disadvantages of the above structure are as follows: 1. It cannot be successfully docked with the blow molding machine, that is to say, it cannot be equipped or connected to the blow molding machine, it is a single vertical cutting device; 2. The overall structure is complicated and the operation It is difficult to implement, because the freedom of movement of the bottle mouth is large, which causes many unstable factors, and it is easy to cause irregular cuts to be scrapped. Therefore, it must be positioned by means of the guide positioning roller to form three stable fulcrums (two rollers). Adding a disc knife) can realize the cutting; Third, conveying the bottle to be cut off by the conveyor belt, not only makes the whole device occupy a large space, but also can not be reflected on the blow molding machine to cut off the flash edge online.

In the case of the Japanese Patent Laid-Open No. Sho 62-128715, JP-A-H11-114975A discloses a mouth-to-edge cutting device for a hollow container, the technical contribution of which is to ensure that the mouth of the hollow container does not deform, the cut is beautiful, and the whole machine is inexpensive. . Applicants found that it also has the following deficiencies: First, it cannot be integrated with the blow molding machine, and it is also a set of independent devices, which can not be reflected in the online cutting flash on the blow molding machine. Second, it is composed of the cutting mechanism. The extrusion is not the rotary cutting, so in addition to stretching a fixed head into the container of the hollow container, it is also supported by the clamping member, otherwise the bottle mouth will be deformed; After an action, the cutting arm has to be opened and closed, and the adjustment mechanism for the cutting arm to be opened and combined for the upper, lower, front and rear adjustment is relatively complicated. The fourth is to use a conveyor belt to feed the hollow container to be cut off. Cutting to the cutting mechanism also makes the entire cutting device occupy a large space. Fifth, the overall structure is complicated and not economical. For example, it is also equipped with an air blowing mechanism for blowing the flashed edge. '

German Patent DE 2 261 246 A discloses a process and a device for forming a plastic hollow part. In addition to the blow molding mechanism, a patented hollow member is introduced adjacent to the separation site of the waste member (flash). The clamping mechanism and a separating mechanism for separating the waste member and a gas supply mechanism for blowing air into the hollow member while separating the waste member. The clamping mechanism is composed of two grippers as a vacuum gripper (the specific structure of the vacuum gripper is not revealed). The shaft of the separating mechanism is a hollow sleeve, which is arranged on the slider, and the cutter arm is fixed at the lower end of the hollow sleeve, and the cutter is fixed on the cutter arm, and the cutter of the cutter must be inserted into the bottle mouth to be rotated and cut, and exited. / The insertion distance is determined by the gap between the air supply pipe and the shaft. A piston device is arranged on one side of the slider to control the distance the slider moves; the air supply mechanism is embodied by the hollow shaft structure. An inflation tube is provided in the hollow shaft to maintain the air pressure in the hollow member at the time of cutting. One of the shortcomings of this technical solution also has the drawback that it cannot be organically formed with the blow molding machine, because it is objectively not given technical inspiration that can be combined with the blow molding machine, for example The waste separation mechanism is supported on the bracket, it cannot The internal and external templates of the blow molding machine are linked; the second, the vacuum gripper moves the hollow member, the blowing mechanism blows into the hollow member, and the separating mechanism divides the removal of the waste into different ones. After the stages are completed, they cannot be synchronized with the blow molding machine's movements. Therefore, the work efficiency cannot be displayed. Third, since the tool's exit/insertion movement distance is determined by the gap between the air supply pipe and the shaft, when the tool is Improper adjustment of the moving distance will damage the air supply pipe or damage the tool by the air supply pipe; Fourth; only continuous continuous air supply to the hollow member to ensure the air pressure in the hollow member can be cut, therefore, due to the presence of a gas supply mechanism , resulting in a complicated structure of the entire device; fifth, the cutting quality of the waste parts is difficult to guarantee, because a pair of grippers (ie, the bottle device) and the rack, the gear, the hollow shaft, the sleeve, the arm, the cylinder The waste separation mechanism (ie, the cutting edge device) which is formed by the slider, the cutter and the like and which is arranged on the separate bracket is separated from each other, that is to say Equidistant displaced and can not be synchronized between the two grip parts and waste separation mechanism. In this way, the center position of the tool can not be aligned with the separation position on the hollow member held by a pair of grippers, which affects the cutting quality. Then, even if the waste separation mechanism and the pair of grippers disclosed in the patent are respectively reluctantly coupled to the automatic blow molding and blowing machine, the formally exhibits the in-line cutting on the blow molding machine, but due to the discarded pieces There is no structural connection between the separation mechanism and the gripper. Even in the original design, the design requirements that satisfy the mismatch between the two can be fully considered. However, in actual use, the blow molding is blown. The presence of vibration factors of the bottle machine causes vibration deformation, and the variation error of the moving position of the separation mechanism of the waste member cannot be ensured corresponding to the separation position on the hollow member clamped by the gripper. Applicant has found that only the synchronous separation of the waste separation mechanism and the gripper can be synchronized, so that the displacement distance error of the two can be zero, thereby ensuring the separation quality of the separation edge of the cutter at the separation position.

The rotatably placed on the movable seat 13 is realized. This embodiment structure is relative to the embodiment 1 and Example 2 are structurally simple and cost-effective.

Figure 8 illustrates the condition after the bottle rim 44 of the bottle 43 has been removed via the embodiments of Examples 1, 2, and 3. The Applicant selects Figures 2, 6 and in conjunction with Figure 4 to describe the process by which the bottle edge 44 of the bottle 43 is cut away. Figure 4 illustrates a pair of formwork 42 of the structure of the present invention that is respectively associated with an automatic blow molding machine. On both sides, it can be stated that two sets of identical structures can be provided on an automatic blow molding machine. The automatic blow molding machine firstly forms a parison from the die unit 40, and then clamps the parison by the bottle mold clamping mold on the mold base 42 and moves to correspond to the inflation device 41, which is inflated by the inflation device 41. The inflating head is inflated into a bottle 43 with a bottle edge 44, and along with the bottle mold on the mold frame 42, i.e., the inner and outer molds 45, 46 are opened and moved back below the die unit 40. At this time, the bottles 43 suspended on the inflation head of the inflation device 41 correspond exactly between the pair of bottle mold halves 20, 21 of the bottle device of the present invention, as the bottle mold on the mold frame 42 is inside, The mold clamping of the outer molds 45, 46 drives the inner mold connecting plate 2 and the outer mold connecting plate 1 of the present invention to be simultaneously clamped, so that the pair of bottle molds 20, 21 sandwich the bottle 43, and then the inflation of the inflation device 41. The head is moved up, and then the mold base 42 and the bottle mold are moved to correspond to the inflation device 41. At this time, under the action of the power cylinder 27, the cylinder column 26 is extended outward, and the moving seat 13 is moved to move. The blade 18 on the knife bar 15 is cut against the bottom of the bottle edge 44 to be cut, and the state is first cut. As shown in FIG. 5, 6, 7. Immediately after the gas/cylinder 8 is actuated, the cylinder column 10 is rapidly extended, so that the linkage 12 is moved to the right, and the rack 11 is moved to the right. Since the rack 11 is meshed with the driving gear 7, the driving gear 7 is rotated during the right movement of the rack 11, the central shaft 4 is rotated, and the sun gear 30 drives the rotary gear 35 to rotate, so that the rotary shaft 15 rotates. The bottle edge 44 is removed from the bottle 43 until the blade 18 is rotated 360°. Then, with the opening of the inner and outer stencils 45, 46 of the mold base 42, the inner and outer movable mold connecting plates 2, 1 are opened to cause the bottle 43 to fall off, and at the same time, under the action of the power cylinder 27, move The seat 13 returns to its original position, as does the gas/cylinder 8 as well. The bottle edge 34 of the inflated bottle 43 is cut off from this week.
