Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of a penicillin bottle making machine, in particular to a penicillin bottle mouth forming stabilizing device. BACKGROUND

[0002] In the penicillin bottle production process, bottle mouth forming is an important process directly determining product quality, and its forming precision, appearance quality and structural stability directly affect the sealing performance, use safety and market acceptance of the penicillin bottle. The mainstream bottle mouth forming scheme in the industry at present adopts a driven wheel type forming structure, that is, in the process of extruding and forming the bottle mouth, the friction of the bottle body self-rotation drives the mold wheel to passively follow the rotation, and the bottle mouth forming is completed by extrusion of the mold wheel following the rotation of the bottle body.

[0003] However, the existing driven wheel type forming scheme has significant quality short boards in actual application, and the prominent performance is that the bottle mouth is prone to color point and wrinkle defects, which seriously restricts the product qualification rate. The core cause of the color point defect is the multiple pollution risks caused by the dynamic contact of the driven wheel: first, the rotational speed of the passive rotating mold wheel is prone to deviation from the bottle body, causing irregular friction between them, causing the abrasive debris and metal powder adhered to the surface of the mold wheel to fall off and embed in the molten bottle mouth glass; second, the mold wheel frequently contacts different bottle bodies, and the glass residues left over from the previous processing are difficult to completely remove, and are transferred to the new bottle mouth during rotation and fused with the molten glass; third, the dynamic rotation of the mold wheel drives the surrounding air flow, accelerating the adsorption of dust, fibers and other pollutants in the environment to the surface of the mold wheel or the molten bottle mouth.

[0004] Among them, the wrinkle defect is caused by the out-of-control glass flow caused by the lagging rotation of the driven wheel and the unstable stress: on the one hand, the rotation mode of the mold wheel relying on the driving of the bottle body inevitably has a speed difference between the fast rotation of the bottle body and the lagging rotation of the mold wheel, the lagging mold wheel forms a barrier to the molten glass, causing the molten glass to be forced to extrude after local accumulation, forming a layered wrinkle; on the other hand, factors such as shaft sleeve wear and bottle body positioning deviation will cause the contact angle and extrusion force of the mold wheel and the bottle mouth to fluctuate frequently, and the molten glass is prone to stretching or folding under the action of unstable external force; in addition, the dynamic contact of the driven wheel cannot stably control the glass flow speed, causing the filling and forming rhythm of the molten glass to be disorderly, and the difference in flow speed in different areas further aggravates the wrinkle generation.

[0005] The above-mentioned color point and wrinkle defects not only destroy the appearance consistency of the penicillin bottle, but more seriously affect the sealing integrity of the bottle mouth and the purity of the contents, bringing safety hazards to the application in the fields of medicine, food and the like, and increasing the rework cost of enterprises.

[0026] In addition, in the description of the present application, the terms "first", "second" and the like are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0027] As Figures 1-3As shown, it shows a penicillin bottle mouth forming stabilizing device in an embodiment of the application, including a workbench 1, a clamping driving mechanism 2 and several groups of mold assembly 3, the clamping driving mechanism 2 is arranged on the workbench 1, the clamping driving mechanism 2 has several clamping assemblies for clamping and driving the rotation of the to-be-formed bottle body 100, the clamping driving mechanism 2 can drive the clamping assembly and the to-be-formed bottle body 100 to rotate synchronously, and the several groups of mold assembly 3 are arranged circumferentially on the workbench 1, each group of mold assembly 3 has two mold wheels 31 arranged at intervals and capable of moving along the direction of approaching or moving away from each other and a core column 32 located between the two mold wheels 31, wherein the moving direction of the mold wheel 31 is along the radial direction. It should be noted that in the process of extruding and forming the penicillin bottle mouth, the clamping assembly clamps the bottom of the bottle body, so that the bottle body is in an inverted state, the bottle mouth faces downward, and the bottle body rotates downward under the action of the clamping assembly. When the clamping driving mechanism 2 drives the to-be-formed bottle body 100 to move above the core column 32, the core column 32 can be inserted upward and supported inward in the bottle mouth of the to-be-formed bottle body 100, and the two mold wheels 31 move along the direction of approaching each other to extrude and form the outer side wall of the bottle mouth. The most important thing is that the device is different from the traditional device, and the mold wheel 31 does not rotate during the process of contacting and extruding and forming the bottle mouth.

[0028] In the above scheme, during work, the clamping driving mechanism 2 drives the to-be-formed bottle body 100 to rotate and move above the core column 32, and the core column 32 is inserted upward and supported inward in the bottle mouth of the to-be-formed bottle body 100. It can be understood that according to the required forming shape of the inner wall of the bottle mouth and the bottle neck, the outer circumferential wall of the core column 32 is provided with a corresponding forming groove. At the same time, the two mold wheels 31 move along the direction of approaching each other to extrude and form the outer side wall of the bottle mouth. In this process, the mold wheel 31 remains fixed and does not rotate, and only relies on the rotation of the to-be-formed bottle body 100 to complete the extrusion and forming of the bottle mouth.

[0029] Specifically, the original driven wheel mode, the mold wheel 31 rotates with the glass bottle, causing more color points and wrinkles, the main reason is the pollution risk caused by dynamic contact of the mold wheel 31 of the driven wheel mode and the out-of-control glass flow caused by rotation lag, and the mold wheel 31 is fixed and not rotating in the embodiment, which eliminates the dynamic friction pollution, avoids the irregular friction caused by the speed difference, greatly reduces the debris and metal powder generated by the surface wear of the mold wheel, and the debris and metal powder will not be embedded in the molten glass. At the same time, the fixed mold wheel 31 is cleaner and has no secondary pollution, the cleaning range is clear, the surface residues can be targetedly removed before use, the pollutants will not be transferred due to rotation, and there is no air flow caused by dynamic rotation, which reduces the adsorption of environmental impurities and greatly reduces the probability of color point generation; in terms of wrinkles, there is no speed difference to avoid glass accumulation, and the molten glass can flow smoothly along the fixed mold wheel profile. The contact angle and extrusion force of the mold wheel 31 with the bottle opening are constant, the stress is stable, the shape is controllable, the glass heating temperature and processing rhythm can be accurately adjusted, the flow rhythm is matched, and the generation of wrinkles is effectively reduced.

[0030] As shown in Figures 4-7 Further, the mold assembly 3 further includes a mounting seat 33, a bidirectional screw rod motor 35, a nut 36, and a lifting seat 37. The mounting seat 33 is arranged on the workbench 1, two sliding seats 34 are arranged on the mounting seat 33 in sliding mode, the sliding seats 34 correspond to the mold wheels 31 one by one, the bidirectional screw rod motor 35 is arranged in the mounting seat 33, the screw rod of the bidirectional screw rod motor 35 has two screw thread segments with opposite rotation directions, the two screw thread segments are threadedly connected with the two nuts 36, the nuts 36 are fixedly connected with the sliding seats 34 and correspond to the sliding seats 34 one by one, the lifting seat 37 is arranged on the mounting seat 33 and located between the two sliding seats 34, and the core column 32 is arranged at the middle part of the top surface of the lifting seat 37. It should be noted that the lifting seat 37 will not affect the movement of the two sliding seats 34, that is, when the two sliding seats 34 move close to each other to the maximum distance, the two sliding seats 34 just contact or still do not contact the lifting seat 37.

[0031] In the above scheme, after the clamping driving mechanism 2 drives the bottle body 100 to be formed to move above the core column 32, the lifting seat 37 drives the core column 32 to move upward and insert and support in the bottle opening, then the bidirectional screw rod motor 35 is started to drive the two nuts 36 to move in opposite directions, the nuts 36 drive the corresponding sliding seats 34 to move close to each other, the mold wheels 31 on the sliding seats 34 move close to the bottle opening and extrude and form the outer side wall of the bottle opening, after the forming is completed, the bidirectional screw rod motor 35 is reversely operated to drive the sliding seats 34 and the mold wheels 31 to move away from each other, and the lifting seat 37 drives the core column 32 to move downward and separate from the bottle opening.

[0032] The embodiment can precisely control the approaching distance and extrusion degree of the two mold wheels 31 by driving the sliding seat 34 to move through the bidirectional screw rod motor 35, ensure the stable contact state of the mold wheel 31 and the bottle mouth, and avoid wrinkles caused by unstable stress; the inner supporting position of the core column 32 is more accurate by driving the core column 32 to ascend and descend by the lifting seat 37, further ensure the molding precision of the bottle mouth, and reduce the color spots and wrinkles from the dynamic contact control and structural positioning, and improve the product qualification rate.

[0033] As shown in Figures 4-5 Further, the sliding seat 34 is provided with a mold wheel intermittent rotation control assembly 4, which includes a support 2, a rotation driving assembly and a wiping block 46. The rotation driving assembly includes a ratchet wheel 41, a pushing piece 43, a fixed plate 44, a limiting pawl 45, a swing rod 47 and a pushing pawl 48. First of all, it should be pointed out that the mold wheel intermittent rotation control assembly 4 can be used to drive the mold wheel to rotate intermittently, so that the circumferential different positions of the mold wheel contact the bottle body each time, reducing the influence of the heat of the mold wheel on the bottle body. The wiping block 46 can be a sponge block or a wiping cloth stacked into a block structure, and the wiping block 46 can be detachably connected with the fixed plate 44. In addition, the pushing piece 43 is a small electric push rod. Specifically, the ratchet wheel 41 is arranged on the mold wheel 31 for driving the mold wheel 31 to rotate. The support 42 is arranged on the sliding seat 34, and the pushing piece 43 is installed on the support 42. The fixed plate 44 is arranged on the support 42, and the limiting pawl 45 is installed on the fixed plate 44. The limiting pawl 45 is engaged with the ratchet wheel 41. The wiping block 46 is arranged on the bottom surface of the fixed plate 44 and abuts against the outer circumferential wall of the mold wheel 31. One end of the swing rod 47 is rotatably connected with the shaft of the ratchet wheel 41, and the other end is hingedly connected with the pushing end of the pushing piece 43. The pushing pawl 48 is arranged on the swing rod 47.

[0034] In the above scheme, when the mold wheel 31 needs to move and adjust the position, the pushing piece 43 is started and elongated, drives the swing rod 47 to swing, and the swing rod 47 drives the pushing pawl 48 to push the ratchet wheel 41 to rotate. The ratchet wheel 41 will drive the mold wheel 31 to rotate synchronously. At the same time, the wiping block 46 abutting against the outer circumferential wall of the mold wheel 31 wipes the rotating mold wheel 31. The limiting pawl 45 is always engaged with the ratchet wheel 41 during the rotation of the ratchet wheel 41. When the pushing piece 43 is shortened and retracted, the swing rod 47 drives the pushing pawl 48 to reset. At this time, the ratchet wheel 41 does not reverse under the limiting action of the limiting pawl 45, ensuring the stability of the mold wheel 31. When the mold wheel 31 moves to the processing position for extrusion molding, the pushing piece 43 stops working. Under the limiting action of the pushing pawl 48 and the limiting pawl 45, the mold wheel 31 remains fixed and does not rotate.

[0035] The mold wheel 31 of the driven wheel mode needs to frequently contact different glasses, and the surface residual last processing residues are difficult to clean thoroughly, and the contaminants are easily transferred during rotation to generate color spots. In the embodiment, the intermittent rotation control assembly 4 is used to realize the rotation wiping of the mold wheel 31 during movement, and the wiping block 46 can completely remove the abrasive debris, metal powder and last processing residues on the surface of the mold wheel 31. The limiting pawl 45 ensures the one-way stable rotation of the mold wheel 31 during wiping, so that the wiping is more thorough. When processing, the mold wheel 31 is fixed and does not rotate to avoid re-adsorbing impurities after wiping. Combined with the anti-pollution advantage of the fixed mold wheel 31 itself, the color spot generation path is further blocked from the cleaning point of view. At the same time, the structure of the intermittent rotation control assembly 4 does not affect the fixed state of the mold wheel 31 during processing, ensuring the stability of the molding.

[0036] Further, torsional springs are arranged on the wheel shafts of the pushing pawl 48 and the limiting pawl 45, and the torsional springs are used to drive the pushing pawl 48 and the limiting pawl 45 to press tightly against the outer peripheral wall of the ratchet wheel 41. Because the ratchet wheel 41, the pushing pawl 48 and the limiting pawl 45 are all arranged horizontally, the ratchet wheel 41 cannot be tightly abutted by the self-weight of the pawl. The torsional springs can ensure that the pushing pawl 48 and the limiting pawl 45 are always tightly attached to the ratchet wheel 41.

[0037] In the above scheme, when the pushing piece 43 drives the swing lever 47 to swing, the torsional spring on the pushing pawl 48 always applies pressure to make the pushing pawl 48 tightly attached to the tooth surface of the ratchet wheel 41, so as to ensure that the pushing pawl 48 can effectively drive the ratchet wheel 41 to rotate. The torsional spring on the limiting pawl 45 also applies pressure to make the limiting pawl 45 tightly meshed with the tooth surface of the ratchet wheel 41, so as to prevent the ratchet wheel 41 from rotating in the non-pushing direction. During the rotation wiping of the mold wheel 31, the pressure of the torsional spring makes the meshing between the pawl and the ratchet wheel 41 always stable, and even if the ratchet wheel 41 slightly vibrates, the meshing will not be separated. After the wiping is completed, the pushing piece 43 is reset, and the torsional spring drives the pushing pawl 48 and the limiting pawl 45 to keep the state of being attached to the ratchet wheel 41.

[0038] The torsional spring can ensure that the pawl is always tightly attached to the ratchet wheel 41, avoid slipping, and make the mold wheel 31 more smoothly and intermittently rotate. The wiping block 46 can uniformly wipe the peripheral wall of the mold wheel 31 and completely remove the surface impurities.

[0039] As shown in FIG. 1, Figures 6-7 Further, the mounting cylinder 5 is arranged on the sliding seat 34, the wheel shaft of the mold wheel 31 is rotatably arranged on the mounting cylinder 5, and the oil injection nozzle 6 is arranged on the outer side wall of the mounting cylinder 5 and faces the core column 32. Specifically, an oil passing channel can be formed in the inner side wall of the mounting cylinder 5, the oil passing channel is communicated with the oil injection nozzle 6, and the oil passing channel is further externally connected with an oil can through a hose. Alternatively, the hose can be directly communicated with the oil injection nozzle 6, and the hose is arranged on the outer side of the mounting cylinder 5 and is directly connected with the oil injection nozzle 6.

[0040] In the above scheme, after the bottle mouth forming is completed, the lifting seat 37 drives the core column 32 to move downward to separate from the bottle mouth, at this time the oil injection nozzle 6 on the installation cylinder 5 is started to inject lubricating oil to the outer peripheral wall of the core column 32, the lubricating oil uniformly covers the surface of the core column 32, after the lubrication is completed, the oil injection nozzle 6 stops working, and waits for the next use of the core column 32. Through the timely injection of lubricating oil by the oil injection nozzle 6 during the process of the core column 32 moving downward after separating from the bottle body, the friction and wear between the core column 32 and the inner wall of the bottle mouth are reduced.

[0041] As shown in Figure 8 , further, the lifting seat 37 is provided with a collection groove 7, the bottom of the collection groove 7 is provided with an oil discharge port, and the collection groove 7 is provided with a flow guide plate 8, the flow guide plate 8 is used for guiding the lubricating oil in the collection groove 7 to the oil discharge port, and the core column 32 is arranged on the flow guide plate 8, and the core column 32 can be lifted synchronously with the collection groove 7.

[0042] In the above scheme, when the oil injection nozzle 6 injects lubricating oil to the core column 32, the excess lubricating oil will drop into the collection groove 7 below, the flow guide plate 8 in the collection groove 7 guides the dropped lubricating oil to the bottom oil discharge port, the lubricating oil is discharged from the collection groove 7 through the oil discharge port for recycling or processing, and the core column 32 is lifted synchronously with the collection groove 7 on the flow guide plate 8, without affecting the internal support forming effect of the bottle mouth. If the lubricating oil injected by the oil injection nozzle 6 drops to the workbench 1 or the vicinity of the molten glass, pollution or equipment failure is easily caused, while the collection groove 7 and the flow guide plate 8 of the embodiment can collect the excess lubricating oil in time, process it through the oil discharge port, avoid the lubricating oil from polluting the environment of the workbench 1 or dropping onto the molten glass to produce color spots, the recycled lubricating oil can be used again after processing, the lubricating oil consumption cost is reduced, the working environment of the device is kept clean, and the bottle mouth defects caused by environmental impurities are reduced.

[0043] As shown in Figure 1 and Figure 10 , further, the workbench 1 is further provided with a plurality of heating assemblies 9 for heating the bottle mouth of the to-be-formed bottle body 100, the heating assemblies 9 correspond to the mold assemblies 3 one by one, the heating assemblies 9 are arranged on one side of the mold assemblies 3, and the heating assembly 9 comprises a lifting adjusting seat 91, a clamp 92 and a flame heating gun 93.

[0047] As shown in Figure 1As shown, the clamping drive mechanism 2 further includes a driver 21, a sleeve 22, a key shaft 23, a clamping head 24, and a lifting actuating member 25. The driver 21 is mounted on the turntable 10. The output end of the driver 21 passes through the turntable 10 and is provided with a sleeve 22. The sleeve 22 has a keyway. The key shaft 23 is slidably mounted in the sleeve 22. The clamping head 24 is located at the end of the key shaft 23 for clamping the bottle body 100 to be formed. The lifting actuating member 25 is mounted on the turntable 10. The lifting actuating member 25 has a actuating end, which is connected to the key shaft 23 for driving the key shaft 23 to slide up and down along the keyway to adjust the height of the clamping head 24 and the bottle body 100 to be formed.

[0048] In the above scheme, the bottle body 100 to be formed is clamped and fixed by the clamping head 24. The driver 21 is started to drive the sleeve 22 to rotate. The sleeve 22 drives the key shaft 23 and the clamping head 24 to rotate through the keyway, which in turn drives the bottle body to rotate. When it is necessary to adjust the height of the bottle body to match the core column 32 and the mold wheel 31, the actuating end of the lifting actuating component 25 drives the key shaft 23 to slide up and down along the keyway of the sleeve 22. The key shaft 23 drives the clamping head 24 and the bottle body to rise and fall synchronously. After adjusting to a suitable height, the lifting and falling stops. The bottle body is squeezed and formed by the mold wheel 31 while rotating.

[0049] In this embodiment, the drive 21 drives the sleeve 22 and key shaft 23 to achieve stable rotation of the bottle. The key shaft 23 and the keyway of the sleeve 22 cooperate to ensure stable power transmission during rotation and avoid fluctuations in the rotation speed of the bottle. The lifting and actuating component 25 drives the key shaft 23 to move up and down precisely, so that the bottle mouth can be accurately aligned with the core column 32 and the mold wheel 31, ensuring constant contact angle and extrusion pressure.

The mounting plate 251 is detachably mounted on the side wall of the turntable 10. The lifting device 252 is mounted on the mounting plate 251. The shift fork 253 is mounted on the movable end of the lifting device 252. The actuating end of the shift fork 253 is provided with a self-rotating connecting ring 254. The connecting ring 254 is fixedly sleeved on the key shaft 23.

[0051] In the above scheme, when the bottle height needs to be adjusted, the lifting device 252 is activated to drive the movable end of the fork 253 to rise and fall. The fork 253 drives the key shaft 23 to rise and fall along the keyway of the sleeve 22 through the connecting ring 254 at the actuating end. The key shaft 23 drives the clamping head 24 and the bottle to rise and fall synchronously. When the key shaft 23 rotates with the sleeve 22 and drives the bottle to rotate, the connecting ring 254 can rotate on its own to prevent the fork 253 from rotating with the key shaft 23, thus ensuring the stable state of the lifting device 252 and the fork 253. The mounting plate 251 is detachable to facilitate the maintenance or replacement of the lifting actuating component 25.

[0052] The connecting ring 254 of the embodiment can rotate, realizing flexible connection between the lifting shift 25 and the rotating key shaft 23, ensuring effective transmission of lifting force, avoiding interference of the rotation of the key shaft 23 on the lifter 252 and the shift 253, making the lifting of the bottle body more stable and accurate, further improving the positioning accuracy of the bottle mouth and the mold wheel 31 and the core column 32, and the detachable mounting plate 251 facilitates equipment maintenance, reduces maintenance difficulty and cost, ensures long-term stable operation of the device, improves production continuity and product quality.
