Description

Technical Field

[0001] This utility model relates to the field of liquid packaging machine technology, and in particular to a cutting mechanism for a liquid packaging machine. Background Technology

[0002] Liquid packaging machines are specialized mechanical equipment used for packaging liquid products. They are widely used in industries such as food, beverage, daily chemicals, and pharmaceuticals. Their working principle is based on different filling methods. For example, gravity filling under normal pressure is suitable for low-viscosity, non-aerobic liquids; pressure filling is suitable for aerobic liquids, achieved through equal pressure or pressure difference; and vacuum filling is carried out under negative pressure inside the bottle. It mainly consists of a liquid storage tank, a conveying system, a filling head, a sealing device, a labeling device, and a control system. All parts work together to automatically complete the processes of liquid extraction, conveying, filling, sealing, and labeling. This equipment can not only significantly improve production efficiency and reduce labor costs, but also has advantages such as high-precision filling, diverse packaging options, and good hygiene and safety performance, meeting the packaging needs of different liquid products.

[0003] However, after prolonged use, the cutting blades of liquid packaging machines are prone to wear. Moreover, since most blades are designed as a single piece, disassembly is inconvenient. This not only increases the difficulty and time cost of maintenance and replacement but also makes it difficult to repair worn blades in a timely manner. This can lead to decreased cutting accuracy and poor cut quality, affecting packaging efficiency and product quality. Utility Model Content

[0004] The purpose of this utility model is to solve the problems in the existing liquid packaging machine cutting mechanism where the blades are easily worn after long-term use, and the blades are mostly one-piece designs, which makes disassembly inconvenient. This not only increases the difficulty and time cost of maintenance and replacement, but also makes it difficult to repair worn blades in a timely manner, which can easily lead to a decrease in cutting accuracy and a deterioration in cut quality, affecting packaging efficiency and product quality. Therefore, a liquid packaging machine cutting mechanism is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a cutting mechanism for a liquid packaging machine, comprising a blade holder and a maintenance device. A cylinder is fixedly mounted on one side of the blade holder, and a drive rod is fixedly mounted on the drive end of the cylinder. A slide is slidably connected to the surface of the blade holder. The end of the drive rod away from the cylinder is fixedly connected to the slide. A blade is disposed on the surface of the slide. The maintenance device is disposed on one side of the slide. The maintenance device includes a placement plate, which is fixedly connected to the slide. A rod is fixedly connected to the surface of the placement plate. A through hole is formed on the surface of the blade, and the rod passes through the through hole on the surface of the blade. The slide has a groove on its surface, and a baffle is slidably connected to the inner wall of the groove. A push groove is provided on one side of the baffle, and a hanging rod is slidably connected to the inner wall of the push groove on one side of the baffle. A locking block is fixedly connected to the surface of the cutter. By setting up a maintenance device, the cutter can be quickly and conveniently replaced. Through the cooperation of the threaded rod, the abutment, the hanging rod, the locking block and the fixing spring, the cutter can be easily disassembled and installed by simply rotating the threaded rod and pushing and pulling the baffle, reducing the difficulty of replacement, saving time and costs, and ensuring the stability of the cutter fixation, ensuring that the cutter will not loosen when the packaging machine is working, and maintaining cutting accuracy and packaging quality.

[0006] Preferably, a fixing spring is fixedly connected to one side of the hanging rod, and the side of the fixing spring away from the hanging rod is fixedly connected to the baffle. By setting the fixing spring, the function of the fixing spring is to provide elastic force to realize the separation of the hanging rod and the locking block. When the threaded rod is rotated to drive the abutment away from the hanging rod, the fixing spring loses its restraint, and the elastic force it generates will pull the hanging rod, causing the hanging rod to disengage from the locking block, thereby creating conditions for the subsequent removal of the tool and facilitating the tool disassembly process.

[0007] Preferably, the upper surface of the placement plate is slidably connected to a stop block, and the upper surface of the placement plate is threadedly connected to a threaded rod. The threaded rod is rotatably connected to the stop block. By setting the threaded rod, when it is necessary to change the tool, rotating the threaded rod will drive the stop block away from the hanging rod, so that the fixing spring is unrestrained, thereby pulling the hanging rod away from the locking block, in preparation for removing the tool.

[0008] Preferably, the surface of the abutment block is provided with a guide surface, and the surface of the hanging rod is provided with an inclined surface. The abutment block contacts the hanging rod. By setting the hanging rod, one end of the hanging rod is connected to a fixed spring, so that the cutter can establish contact with other parts of the entire maintenance device through the hanging rod.

[0009] Preferably, the surface of the placement plate is provided with a reset assembly, which includes a column that is slidably connected to the placement plate. A push plate is fixedly connected to the upper surface of the column. By setting the reset assembly, the tool disassembly process is further simplified. When the baffle is disengaged from the tool, the pressure spring drives the push plate to automatically push the tool out of the insert rod, eliminating the need for manual and laborious removal. This makes the operation easier and more efficient, improves maintenance efficiency, and reduces damage to the tool or equipment caused by improper manual disassembly.

[0010] Preferably, there are two columns, which are symmetrically arranged. The push plate contacts the cutter. By setting the columns, it is easy to cooperate with the push plate to squeeze the cutter out of the assembly plate, making it convenient for the user to remove the cutter and increasing the ease of use of the equipment.

[0011] Preferably, a pressure spring is fixedly connected to the lower surface of the push plate, and the end of the pressure spring away from the push plate is fixedly connected to the placement plate. By setting the pressure spring, when the baffle is disengaged from the tool, the elastic force generated by the baffle after it is unrestrained will squeeze the push plate, causing the push plate to move upward, thereby pushing the tool out of the insert rod, so as to remove the tool more conveniently and play a role in assisting the disassembly of the tool.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, by setting up a maintenance device, when the blade is severely worn and needs to be replaced, rotating the threaded rod drives the stop block away from the hanging rod. At this time, the fixing spring loses its restraint and generates elastic force to pull the hanging rod away from the locking block. Then, pull the baffle backward, and the baffle moves away from the blade, so the blade can be removed. The new blade and the insert rod can then be inserted. Subsequently, push the baffle against the blade. When the baffle is against the locking block, rotate the threaded rod. The threaded rod pushes the stop block to squeeze the hanging rod and the locking block into place, completing the replacement and fixing. By setting up a maintenance device, the blade can be replaced quickly and conveniently. Through the cooperation of the threaded rod, the stop block, the hanging rod, the locking block and the fixing spring, the blade can be easily disassembled and installed by simply rotating the threaded rod and pushing and pulling the baffle, reducing the difficulty of replacement, saving time and costs, and ensuring the stability of the blade fixing, ensuring that the blade will not loosen when the packaging machine is working, and maintaining cutting accuracy and packaging quality.

[0014] 2. In this utility model, by setting a reset component, when the baffle is disengaged from the tool, the pressure spring loses its restraint and generates elastic force to squeeze the push plate. The push plate moves upward under force and pushes the tool out of the insert rod, thus removing the tool. By setting a reset component, the tool disassembly process is further simplified. When the baffle is disengaged from the tool, the pressure spring drives the push plate to automatically push the tool out of the insert rod, eliminating the need for manual and laborious removal. This makes the operation easier and more labor-saving, improves maintenance efficiency, and reduces damage to the tool or equipment caused by improper manual disassembly. Attached Figure Description

[0021] Please see Figures 1-5 This utility model provides a technical solution: a cutting mechanism for a liquid packaging machine.

[0022] In this embodiment, a tool holder 1 and a maintenance device 6 are included. A cylinder 2 is fixedly installed on one side of the tool holder 1. A drive rod 3 is fixedly installed on the drive end of the cylinder 2. A slide 4 is slidably connected to the surface of the tool holder 1. The end of the drive rod 3 away from the cylinder 2 is fixedly connected to the slide 4. A cutting tool 5 is provided on the surface of the slide 4. The maintenance device 6 is provided on one side of the slide 4.

[0023] Specifically, the maintenance device 6 includes a placement plate 61, which is fixedly connected to the slide 4. A rod 62 is fixedly connected to the surface of the placement plate 61. A through hole is opened on the surface of the blade 5, and the rod 62 is inserted into the through hole on the surface of the blade 5. A sliding groove is opened on the surface of the slide 4, and a baffle 63 is slidably connected to the inner wall of the sliding groove on the surface of the slide 4. A push groove is opened on one side of the baffle 63, and a hanging rod 66 is slidably connected to the inner wall of the push groove on one side of the baffle 63. A locking block 65 is fixedly connected to the surface of the blade 5. By setting up the maintenance device 6, the blade 5 can be quickly and conveniently replaced. Through the cooperation of the threaded rod 67, the abutment 68, the hanging rod 66, the locking block 65 and the fixing spring 69, the blade 5 can be easily disassembled and installed by simply rotating the threaded rod 67 and pushing and pulling the baffle 63, reducing the difficulty of replacement, saving time and costs, and ensuring the stability of the blade 5, ensuring that the blade 5 will not loosen when the packaging machine is working, and maintaining cutting accuracy and packaging quality.

[0024] Specifically, a fixing spring 69 is fixedly connected to one side of the hanging rod 66. The side of the fixing spring 69 away from the hanging rod 66 is fixedly connected to the baffle 63. By setting the fixing spring 69, the function of the fixing spring 69 is to provide elastic force to separate the hanging rod 66 from the locking block 65. When the threaded rod 67 is rotated to drive the stop block 68 away from the hanging rod 66, the fixing spring 69 loses its restraint, and the elastic force it generates will pull the hanging rod 66, causing the hanging rod 66 to disengage from the locking block 65, thereby creating conditions for the subsequent removal of the tool 5 and facilitating the disassembly process of the tool 5.

[0025] Specifically, a stop block 68 is slidably connected to the upper surface of the placement plate 61, and a threaded rod 67 is threadedly connected to the upper surface of the placement plate 61. The threaded rod 67 is rotatably connected to the stop block 68. By setting the threaded rod 67, when it is necessary to change the tool 5, rotating the threaded rod 67 will drive the stop block 68 away from the hanging rod 66, so that the fixing spring 69 is unrestrained, thereby pulling the hanging rod 66 away from the locking block 65, in preparation for removing the tool 5.

[0026] Specifically, the surface of the abutment 68 is provided with a guide surface, and the surface of the hanging rod 66 is provided with an inclined surface. The abutment 68 contacts the hanging rod 66. By setting the hanging rod 66, one end of the hanging rod 66 is connected to the fixed spring 69, so that the tool 5 can establish a connection with other parts of the entire maintenance device 6 through the hanging rod 66.

[0027] Specifically, a reset assembly 64 is provided on the surface of the placement plate 61. The reset assembly 64 includes a column 642, which is slidably connected to the placement plate 61. A push plate 641 is fixedly connected to the upper surface of the column 642. By setting the reset assembly 64, the disassembly process of the tool 5 is further simplified. When the baffle 63 is disengaged from the tool 5, the pressure spring 643 drives the push plate 641 to automatically push the tool 5 out of the insertion rod 62. There is no need to manually pull it out with great effort, making the operation easier and more labor-saving, improving maintenance efficiency, and reducing damage to the tool 5 or equipment caused by improper manual disassembly.

[0028] Specifically, there are two columns 642, which are symmetrically arranged, and the push plate 641 is in contact with the cutter 5.

[0029] In this embodiment, the column 642 is provided to facilitate the push plate 641 to push the cutter 5 out of the assembly plate, making it easier for the user to remove the cutter 5 and increasing the ease of use of the equipment.

[0030] Specifically, a pressure spring 643 is fixedly connected to the lower surface of the push plate 641, and the end of the pressure spring 643 away from the push plate 641 is fixedly connected to the placement plate 61.

[0031] In this embodiment: by setting a pressure spring 643, when the baffle 63 is disengaged from the cutter 5, the elastic force generated by the baffle 63 after it is freed from restraint will squeeze the push plate 641, causing the push plate 641 to move upward, thereby pushing the cutter 5 out of the insert rod 62, so as to remove the cutter 5 more easily, thus playing the role of assisting in the disassembly of the cutter 5.

[0032] Working principle: By setting up maintenance device 6, when the tool 5 is severely worn and needs to be replaced, rotating the threaded rod 67 drives the abutment block 68 away from the hanging rod 66. At this time, the fixing spring 69 loses its restraint and generates elastic force to pull the hanging rod 66 away from the locking block 65. Then, pull the baffle 63 backward, and the baffle 63 moves away from the tool 5, so the tool 5 can be removed. The new tool 5 is then inserted into the insertion rod 62. Subsequently, push the baffle 63 to abut against the tool 5. When the baffle 63 abuts against the locking block 65, rotate the threaded rod 67, and the threaded rod 67 pushes the abutment block 68 away from the tool 5. Block 68 presses the hanging rod 66 and the locking block 65 together to complete the replacement and fixation. By setting up the maintenance device 6, the tool 5 can be quickly and conveniently replaced. With the cooperation of the threaded rod 67, the abutment block 68, the hanging rod 66, the locking block 65 and the fixing spring 69, the tool 5 can be easily disassembled and installed by simply rotating the threaded rod 67 and pushing and pulling the baffle 63, which reduces the difficulty of replacement, saves time and costs, and at the same time ensures the stability of the tool 5, ensuring that the tool 5 will not loosen when the packaging machine is working, and maintaining cutting accuracy and packaging quality.

[0033] By setting the reset component 64, when the baffle 63 disengages from the tool 5, the pressure spring 643 loses its restraint and generates elastic force to squeeze the push plate 641. The push plate 641 moves upward under force and pushes the tool 5 out of the insertion rod 62, thus removing the tool 5. By setting the reset component 64, the disassembly process of the tool 5 is further simplified. After the baffle 63 disengages from the tool 5, the pressure spring 643 drives the push plate 641 to automatically push the tool 5 out of the insertion rod 62, eliminating the need for manual and laborious removal. This makes the operation easier and less strenuous, improves maintenance efficiency, and reduces damage to the tool 5 or equipment caused by improper manual disassembly.
