Description

Technical Field

[0001] The utility model relates to the technical field of filling and punching, and in particular to a punching device of an oral liquid filling and sealing machine. Background Art

[0002] The filling machine is a fully automatic filling device that preheats, seals, and forms plastic sheets, and then fills them with liquid and semi-liquid products. The filling machine's sealing and forming molds are usually 8, but in order to speed up the process, the 8 molds were changed to 12, and the number of injections per time was also increased from 8 to 12. Since the filling machine runs at a speed of 25 beats per minute, the cutting unit punches out a single medicine stick at a time, cutting off every 6 sticks. The punching speed was increased from 200 times / minute to 300 times / minute. The high-speed punching caused an extremely high failure rate of the various firmware of the punching cutter. After reducing the operating speed and the punching speed, it was reduced to 264 times / minute, but failures still occurred frequently, seriously affecting the production schedule and failing to meet the expected production targets. In addition, the punching efficiency of the existing punching machine is relatively low. Utility Model Content

DETAILED DESCRIPTION

[0057] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, they can also be understood as further technical solutions without paying creative work. In some figures, components with the same structure or function are schematically illustrated, or only one of them is marked. In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0058] It should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0059] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0060] Reference Figures 1 to 9, which is the first embodiment of the present utility model, proposes a punching device for an oral liquid filling machine, including: a frame 100; a first cutting member 200, which is slidably set on the frame 100; a second cutting member 300, which is slidably set on the frame 100, and a cutting gap 210 is provided between the first cutting member 200 and the second cutting member 300. The raw material passes through the cutting gap 210, and the first cutting member 200 and the second cutting member 300 are close to each other to cut the raw material.

[0061] In this embodiment, the raw material is a row of plastic boxes filled with oral liquids. After punching, individual bottles can be separated from the others by cutting holes between adjacent bottles. The bottles can then be opened by rotating the top of the bottles. Before cutting, the bottles cannot be opened and can only be separated using scissors or other methods. To improve the punching efficiency of the punching machine, this embodiment first redesigns the single punching mechanism into a dual punching mechanism, enabling two bottles to be punched at a time. Secondly, the first cutting member 200 and the second cutting member 300 are designed to slide in opposite directions. The raw material is cut after the first and second cutting members 200 and 300 approach each other. In actual operation, the oral liquid filling machine transports the raw material to be cut to the cutting gap 210. When cutting is required, the first and second cutting members 200 and 300 approach each other. The sharp blades of the first and second cutting members 200 and 300 enable quick and accurate cutting of the raw material. After cutting is completed, the first and second cutting members 200 and 300 return to their original positions, ready for the next cutting operation. Furthermore, the first cutting member 200 and the second cutting member 300 slide simultaneously, thereby increasing cutting efficiency.

[0062] Furthermore, it also includes a driving member 400, which includes: a driving unit 410, which is arranged on the frame 100; a first sliding bar 420, which is slidably arranged on the frame 100 and is arranged on the driving unit 410, and the first cutting member 200 is arranged on the first sliding bar 420. The driving unit 410 is used to drive the first sliding bar 420 to slide, and after the first sliding bar 420 slides, it drives the first cutting member 200 to slide; a second sliding bar 430, which is slidably arranged on the frame 100 and is arranged on the driving unit 410, and the second cutting member 300 is arranged on the second sliding bar 430. The driving unit 410 is used to drive the second sliding bar 430 to slide, and after the second sliding bar 430 slides, it drives the second cutting member 300 to slide.

[0063] In this embodiment, a drive unit 410 is provided to enable the sliding of the first cutting member 200 and the second cutting member 300. The drive unit 410 is mounted on the frame 100 and is a device that can provide a linear driving force. A first slide bar 420 and a second slide bar 430 are slidably mounted on the frame 100. When the drive unit 410 is activated, it pushes the first slide bar 420 and the second slide bar 430 to slide back and forth on the frame 100. The sliding directions of the first slide bar 420 and the second slide bar 430 are always opposite, thereby driving the first cutting member 200 and the second cutting member 300 toward and away from each other. During actual operation, the drive unit 410 can synchronously push the first slide bar 420 and the second slide bar 430 to slide according to a preset program or signal, so that the first cutting member 200 and the second cutting member 300 approach each other at an appropriate speed, thereby punching and cutting the raw material passing through the cutting gap 210.

[0064] The drive unit 410 controls the sliding motion of the first cutting member 200 and the second cutting member 300 via the first and second sliding rods 420 and 430, respectively, enabling precise control of the cutting action and ensuring accurate and consistent position and force for each cut. Because the drive unit 410 acts simultaneously on the first and second sliding rods 420 and 430, the movement of the first and second cutting members 200 and 300 is synchronized, improving cutting quality and efficiency. Different types of drive units 410 can adjust output power and speed based on actual production needs, adapting to the cutting requirements of materials of varying thicknesses and materials.

[0065] Furthermore, the driving unit 410 includes: a rotating shaft 440, which is rotatably set on the frame 100; a first eccentric wheel 450, which is eccentrically set on the rotating shaft 440, and the first slide bar 420 is set on the first eccentric wheel 450; a second eccentric wheel 460, which is eccentrically set on the rotating shaft 440, and the second slide bar 430 is set on the second eccentric wheel 460. After the first eccentric wheel 450 and the second eccentric wheel 460 rotate, they drive the first slide bar 420 and the second slide bar 430 to slide in opposite directions.

[0066] In this embodiment, a bearing seat is mounted on the frame 100, and the rotating shaft 440 is mounted on the bearing seat via a bearing, enabling rotation. The rotating shaft 440 can be driven to rotate by a motor via a belt drive, gear drive, or other means. The first eccentric wheel 450 and the second eccentric wheel 460 are eccentrically fixed to the rotating shaft 440 via a key connection or other means. One end of the first sliding rod 420 is mounted on the first eccentric wheel 450 via a connecting structure such as a connecting pin, and one end of the second sliding rod 430 is similarly mounted on the second eccentric wheel 460 via a connecting structure. When the rotating shaft 440 rotates under the drive of a motor or other driving device, the first eccentric wheel 450 and the second eccentric wheel 460 rotate accordingly. Because the first eccentric wheel 450 and the second eccentric wheel 460 are eccentrically arranged and eccentric in opposite directions, they cause the first sliding rod 420 and the second sliding rod 430 to slide in opposite directions during rotation.

[0067] In actual work, by reasonably designing the eccentric distance of the eccentric wheel and the rotation speed of the rotating shaft 440, the movement speed and cutting force of the first cutting member 200 and the second cutting member 300 can be accurately controlled to meet the cutting requirements of raw materials of different thicknesses and materials.

[0068] This embodiment, by setting the first eccentric wheel 450 and the second eccentric wheel 460 on the same rotating shaft 440, can ensure that the first slide bar 420 and the second slide bar 430 achieve synchronous reverse sliding, thereby ensuring the motion coordination of the first cutting member 200 and the second cutting member 300, and improving the precision and efficiency of cutting. This embodiment has a compact structure and occupies a small space, and is suitable for installation on an oral liquid filling machine with limited space. The connection between the eccentric wheel and the slide bar is relatively stable, which can ensure the stability of power transmission and reduce cutting errors caused by power fluctuations. By adjusting parameters such as the rotation speed of the rotating shaft 440 and the eccentric distance of the eccentric wheel, the motion characteristics of the first cutting member 200 and the second cutting member 300 can be flexibly changed to adapt to different production requirements.

[0069] Furthermore, the driving member 400 is located on one side of the first cutting member 200. The first cutting member 200 includes: a first mounting seat 220, which is slidably set on the frame 100, and the other end of the first slide bar 420 is set on the first mounting seat 220, and the first mounting seat 220 is slidably set on the second slide bar 430; the second cutting member 300 includes: a second mounting seat 310, which is slidably set on the frame 100, and the other end of the second slide bar 430 is set on the second mounting seat 310; the first cutting member 200 also includes: a cutter 230, which is slidably set on the first mounting seat The mounting seat 220; the first mold 240 is slidably set on the cutter 230; the elastic member 250, one end of which is set on the first mold 240 and the other end is set on the cutter 230, and the elastic member 250 is used to provide the first mold 240 with a force to reset; the second cutting member 300 also includes: a second mold 320, which is set on the second mounting seat 310, and the first mold 240 and the second mold 320 form a cutting gap 210. After the first mold 240 abuts against the second mold 320, the cutter 230 slides out of the first mold 240 for cutting the raw material.

[0070] In this embodiment, the driving member 400 is located on one side of the first cutting member 200. The first cutting member 200 is slidably mounted on the frame 100. The first mounting seat 220 is provided with a sliding hole that mates with the second slide bar 430, allowing the first mounting seat 220 to slide on the second slide bar 430. The other end of the first slide bar 420 is fixedly connected to the first mounting seat 220. When the first slide bar 420 slides under the action of the driving unit 410, it drives the first mounting seat 220 to slide on the frame 100. The cutter 230 is securely mounted on the first mounting seat 220. The first mold 240 has a die hole. The structure of the cutter 230 is identical to the die hole, and the first mold 240 also has an escape groove. The first mold 240 slides onto the cutter 230 through the die hole. The elastic member 250 can be a spring, one end of which is fixed to the first mold 240 and the other end is fixed to the cutter 230. The second mounting base 310 of the second cutting member 300 is also slidably mounted on the frame 100, and the other end of the second slide bar 430 is fixedly connected to the second mounting base 310. The second mold 320 is fixedly mounted on the second mounting base 310 and also has an avoidance groove. The structure of the avoidance groove is the same as that of the raw material.

[0071] During operation, when the drive unit 410 drives the first and second slide bars 420 and 430 to slide in opposite directions, the first and second mounting bases 220 and 310 approach each other. The first die 240 initially contacts the second die 320, with the relief grooves on the first and second dies 240 and 320 clamping the material. As the first and second mounting bases 220 and 310 continue to approach each other, the first die 240 compresses the elastic member 250 under the reaction force of the second die 320, causing the first die 240 to slide over the cutter 230. When the first and second dies 240 and 320 are fully aligned, the cutter 230 slides out of the first die 240 and cooperates with the second die 320 to cut the material between the first and second dies 240 and 320. After cutting is completed, the drive unit 410 drives the first and second slide bars 420 and 430 to move in opposite directions. Under the action of the elastic member 250, the first die 240 returns to its original position, ready for the next cutting operation.

[0072] The cooperation between the first mold 240 and the second mold 320 can ensure accurate cutting of the raw material and improve the cutting quality. The setting of the elastic member 250 can play a buffering role when the first mold 240 contacts the second mold 320, reducing the damage to the device caused by the impact, and also ensure that the first mold 240 can be reliably reset after the cutting is completed. The structure of the first mold 240 and the second mold 320 not only ensures the clamping and centering of the raw material, but also realizes the cutting of the raw material. The first mounting seat 220 and the second mounting seat 310 are respectively slidably set on the frame 100 and the corresponding slide rod, so that the movement of the first cutting member 200 and the second cutting member 300 is more stable, thereby improving the reliability of the device.

[0073] Furthermore, it also includes:

[0074] There are several guide rods 500 , all of which are arranged on the frame 100 . The guide rods 500 form a conveying gap 510 . The conveying gap 510 is used to center the raw materials. The conveying gap 510 leads to the cutting gap 210 .

[0075] In this embodiment, a plurality of guide rods 500 are provided on the frame 100 of the blanking device of the oral liquid filling machine. These guide rods 500 can be made of stainless steel, which provides a certain degree of strength and wear resistance. The number of guide rods 500 can be determined according to actual needs. For example, four guide rods 500 can be provided, each located at the four corners of a rectangle. The guide rods 500 are secured to the frame 100 by welding, bolting, or other means to ensure a secure and stable position. A conveying gap 510 is formed between these guide rods 500. When the oral liquid filling machine conveys raw materials, the raw materials enter the conveying gap 510. The positioning of the guide rods 500 ensures that the raw materials are automatically centered in the conveying gap 510. If the raw materials deviate during conveyance, the guide rods 500 guide and adjust them, gradually returning them to the center of the conveying gap 510. The conveying gap 510 leads to the cutting gap 210, allowing the centered raw materials to enter the cutting position accurately for blanking and cutting. The ends of the guide rod 500 close to the first cutting member 200 and the second cutting member 300 are both chamfered or notched to avoid the cutter 230 and prevent the cutter 230 from being damaged.

[0076] The conveying gap 510 formed by the guide rods 500 can center the raw material and transport it to the cutting gap 210, ensuring the accurate positioning of the raw material during cutting, thereby improving cutting accuracy and reducing scrap rate. If the raw material deviates during transportation, the guide rods 500 can automatically adjust it without additional manual intervention, thereby improving production efficiency. The guide rods 500 provide a stable channel for the transportation of raw materials, preventing them from shaking or jumping during transportation, ensuring the continuity and stability of production. The position and number of guide rods 500 can be adjusted according to the width of raw materials to meet the requirements of punching oral liquid packaging materials of different specifications.

[0077] Furthermore, the frame 100 has a loading area 110 and a buffer area 120, and also includes: a plurality of tensioning wheels 600, all of which are rotatably set on the frame 100 and located in the loading area 110; a loading wheel 700, which is rotatably set on the frame 100 and located in the loading area 110. After the tensioning wheel 600 and the loading wheel 700 rotate, they are used to transport raw materials, and the buffer area 120 is used to store raw materials.

[0078] In this embodiment, the frame 100 is divided into a loading area 110 and a buffer area 120. In the loading area 110, several tensioning wheels 600 are rotatably mounted on the frame 100 via a rotating shaft 440 and a bearing. Since the raw materials in the prior art are in the form of a drum for holding the liquid medicine, and in the form of a thin sheet where the two oral liquids are connected, and there are cracks at the connection to facilitate tearing, the surface of these tensioning wheels 600 can be designed with ridges arranged in a vertical direction, and several ridges are arranged along the circumference of the tensioning wheel 600. When the raw materials are transported, the ridges are stuck at the cracks in the raw materials. The number of tensioning wheels 600 can be set according to actual needs, for example, three tensioning wheels 600 are set, distributed in a triangular shape. The loading wheel 700 is also rotatably mounted in the loading area 110 of the frame 100 via a rotating shaft 440 and a bearing, and the loading wheel 700 also has ridges. The loading wheel 700 can be driven to rotate by a motor through a belt drive or other means. When the loading operation is carried out, the raw material first passes through the tensioning wheel 600. The tensioning wheel 600 conveys the raw material forward during the rotation. At the same time, the tensioning wheel 600 can also play the role of tensioning the raw material. The loading wheel 700 rotates under the drive of the motor, and further conveys the raw material to the conveying gap 510 formed by the guide rod 500 of the punching device. The loading wheel 700 is improved from 31 cavities to 32 cavities, that is, one rotation can convey 32 oral liquids, so as to realize the parameter control of the loading wheel 700 to feed two medicine sticks for punching and cutting at a time. The parameter "number of production packages / per cycle" of the loading wheel 700 is changed from 12 to 6; the cutting unit parameter "number of packages per plate finally divided" is changed from 6 to 3; the loading wheel 700 and the punching parameters realize the control of the loading wheel 700 to feed two medicine sticks for punching and cutting at a time. The hardware and software control the loading wheel 700 to feed two medicine sticks for punching and cutting each time. When the equipment runs at a speed of 25 beats per minute, the punching speed of the cutting unit is reduced to 150 times / minute, and the failure rate is reduced linearly.

[0079] The feeding area 110 is located between the buffer zone 120 and the cutting gap 210. The buffer zone 120 can be a large plane area. When the cutting speed of the blanking device does not match the feeding speed, the buffer zone 120 can store a certain amount of raw materials to play a buffering role.

[0080] The coordination of the tensioning wheel 600 and the feeding wheel 700 ensures stable material transportation during the feeding process, avoiding jams and material breakage. The tensioning wheel 600 can tension the raw material, improving its flatness and straightness, facilitating subsequent punching and cutting operations and improving cutting quality. The buffer zone 120 can act as a buffer, adapting to different production rhythms and improving production flexibility and reliability. When the punching device experiences a temporary malfunction or requires adjustment, the buffer zone 120 can store raw materials, ensuring production continuity, reducing downtime, and improving production efficiency.

[0081] Furthermore, it also includes: a filling piece 800 arranged on the frame 100, and a buffer zone 120 located between the filling piece 800 and the loading area 110.

[0082] In this embodiment, the filling unit 800 may be composed of a liquid storage tank, a filling pump, a filling head, and a control system. The liquid storage tank is used to store the oral liquid to be filled, and the filling pump extracts the liquid from the liquid storage tank and delivers it to the filling head through a pipeline.

[0083] Integrating the filling unit 800 and the blanking device on the same machine frame 100 enables integrated filling and blanking production, reducing equipment footprint and improving production efficiency. A buffer zone 120, located between the filling unit 800 and the loading area 110, provides a buffer space for the raw materials after filling. This facilitates coordinating the production rhythm of various steps, such as filling and blanking, and improves production stability and continuity. This embodiment allows the parameters and layout of the filling unit 800 to be adjusted according to different production requirements to accommodate the production requirements of oral liquid products of varying specifications and types.

[0084] Furthermore, it also includes: a sleeve 900, which is sleeved on the second slide rod 430 and located between the second slide rod 430 and the first mounting seat 220; a plurality of balls 1000, which are rotated at intervals on the sleeve 900, and one end of the ball 1000 abuts the first mounting seat 220, and the other end abuts the second slide rod 430.

[0085] In this embodiment, the sleeve 900 can be made of a wear-resistant metal material, with an inner diameter slightly larger than that of the second slide bar 430 to facilitate smooth insertion onto the second slide bar 430. Several mounting grooves are spaced apart on the outer surface of the sleeve 900 for mounting the balls 1000. The balls 1000 can be stainless steel miniature balls 1000, which are rotatably mounted within the mounting grooves of the sleeve 900. When the first mounting seat 220 slides driven by the first slide bar 420, one end of the balls 1000 on the sleeve 900 abuts the first mounting seat 220 and the other end abuts the second slide bar 430. As the first mounting seat 220 slides, the balls 1000 roll between the first mounting seat 220 and the second slide bar 430, reducing friction between the two. This allows for smoother sliding of the first mounting seat 220, reduces energy loss and wear, and improves the lifespan and stability of the device. The arrangement of sleeve 900 and ball bearing 1000 effectively reduces friction between the first mounting seat 220 and the second slide bar 430, lowering energy consumption during operation and improving energy efficiency. This reduced friction allows for smoother sliding of the first mounting seat 220, minimizing vibration and shaking caused by friction, and improving the overall stability and cutting accuracy of the blanking device. This also reduces wear caused by friction, extending the service life of components such as the first mounting seat 220, the second slide bar 430, the sleeve 900, and the ball bearing 1000, thereby reducing maintenance costs.

[0086] Furthermore, it also includes: two breaking knives 1100, one is set on the first mounting seat 220, and the other is set on the second mounting seat 310. After the first mounting seat 220 and the second mounting seat 310 are close to each other, the two breaking knives 1100 abut against each other; a first cutting knife 1200 is set on the second mounting seat 310; a second cutting knife 1300 is slidably set on the first mounting seat 220, and after the second cutting knife 1300 is close to the first cutting knife 1200, it is used to cut the raw material.

[0087] In this embodiment, when the first mounting seat 220 and the second mounting seat 310 approach each other under the action of the drive unit 410, the two cutting knives 1100 also approach each other and eventually abut each other. The cutting knife 1100 is usually made of high-strength steel and has a sharp blade. It can score the raw materials passing through during the process of the first mounting seat 220 and the second mounting seat 310 approaching each other, forming a fracture line. The fracture line needs to be cut between each adjacent oral liquid to facilitate the subsequent tearing and separation of the oral liquid. The coordinated use of the first cutting knife 1200 and the second cutting knife 1300 can achieve precise cutting of the raw materials, ensuring that the cut section is flat and smooth, meeting the requirements of oral liquid filling. The operator can cut as needed, for example, cutting once every 12 oral liquids.

[0088] Furthermore, it also includes: a blanking member 1400, which is arranged on the frame 100 and has a blanking channel 1410; a guide member 1500, which is arranged on the frame 100 and has a guide gap 1510, and the cutting gap 210, the guide gap 1510 and the blanking channel 1410 are connected in sequence.

[0089] In this embodiment, the blanking member 1400 is mounted on the frame 100 and its main body can be made of sheet metal. The blanking channel 1410 is an inclined channel with a support plate at the bottom and two baffles on the sides. The baffles are inclined and slide on the support plate. The tilt serves to increase the range of motion of the material. After the material is cut, it is pushed into the blanking channel 1410 by the thrust of the subsequent material, making it easier for it to fall out of the blanking channel 1410. When the material tends to fall, it causes the baffles to slide. An elastic member is installed between the baffle and the support plate, and the sliding baffles return to their original position as the elastic member returns to its original position. A guide gap 1510 is provided in the guide member 1500. The width of the guide gap 1510 is slightly larger than the width of the cut material to ensure smooth passage of the cut material. One end of the guide gap 1510 is connected to the cutting gap 210, and the other end is connected to the blanking channel 1410. During operation, after the first and second cutting members 200 and 300 have completed cutting the raw material, the cut raw material, under the thrust of the subsequent raw material, enters the guide gap 1510. Due to the restriction and guidance of the guide gap 1510, the raw material can move accurately toward the discharge channel 1410. The raw material enters the discharge channel 1410 through the guide gap 1510 and is transported to a designated location for subsequent processing or packaging.

[0090] The arrangement of the blanking member 1400 and the guide member 1500 ensures that the cut material leaves the blanking device in an orderly manner, preventing chaotic accumulation or scattering of the material, thereby improving production cleanliness and efficiency. The guide gap 1510 of the guide member 1500 accurately guides the cut material into the blanking channel 1410, ensuring the correct material delivery direction and reducing blockage or damage caused by material deviation.
