Description
A new type of sealing and cutting machine Technical Field
[0001] This utility model relates to the field of sealing and cutting machine technology, and specifically to a novel sealing and cutting machine. Background Technology
[0002] A sealing and cutting machine is a widely used piece of machinery in the packaging industry, primarily used for sealing and cutting various items. It typically consists of a frame, sealing and cutting device, conveying system, and control system. The sealing and cutting device is the core component, equipped with heating elements and cutting blades. It can precisely control temperature and pressure according to different packaging materials and requirements, achieving efficient and stable sealing and cutting. The conveying system smoothly transports the items to be packaged to the sealing and cutting position, improving work efficiency. The control system allows for flexible setting of parameters such as sealing and cutting time and temperature, ensuring precise operation. Sealing and cutting machines are suitable for various packaging materials, such as plastic films and composite films, and can package different types of items, including food, daily necessities, and electronic products. They effectively improve packaging quality and aesthetics, extend product shelf life, and reduce production costs, playing a vital role in modern industrial production.
[0003] CN207404038U discloses a novel heat-sealing and cutting mechanism for plastic packaging film, including a dustproof shell. Inside the dustproof shell are an upper cutter and a lower cutter. A high-frequency heater is located at the end of the lower cutter, and a thermocouple is located at one end of the high-frequency heater. Two parallel support rods are located at the end of the lower cutter, and these support rods are threadedly connected to a lower motor. A forming plate is located at one end of the upper cutter, and two parallel limiting rods are located at the other end of the upper cutter. A fan is hinged to the limiting rods, and the limiting rods are threadedly connected to the upper motor. This technology uses separate drive sources to control the upper and lower cutters, resulting in high manufacturing costs. Furthermore, this technology requires a push-pull rod to allow the upper and lower cutters to feed and retract together via a hinge, making the linkage mechanism complex and cumbersome. Therefore, this technology still has room for improvement. Summary of the Invention
[0004] The technical problem to be solved by this utility model is to provide a new type of sealing and cutting machine to address the shortcomings of the prior art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel sealing and cutting machine, comprising a frame, the frame including a worktable, a frame top plate axially disposed at the top of the frame, and a frame bottom plate disposed at the bottom of the worktable, wherein a movable sealing and cutting device is provided between the frame top plate and the worktable, characterized in that: the movable sealing and cutting device includes an upper sealing and cutting device and a lower sealing and cutting device, the upper sealing and cutting device being disposed between the frame top plate and the worktable, the worktable having a placement slot for placing the lower sealing and cutting device, the frame top plate having a lifting assembly capable of driving the upper sealing and cutting device, and the lower sealing and cutting device and the upper sealing and cutting device being connected by a chain linkage structure so that when the upper sealing and cutting device is raised or lowered, it can drive the lower sealing and cutting device to rise or fall in the opposite direction.
[0006] Using the above technical solution, the movable sealing and cutting device is divided into an upper sealing and cutting device and a lower sealing and cutting device. The upper sealing and cutting device is set between the top plate of the frame and the worktable, and the lower sealing and cutting device is placed in the placement slot of the worktable. The lifting component set on the top plate of the frame can drive the upper sealing and cutting device to rise and fall. The lower sealing and cutting device is connected to the upper sealing and cutting device through a chain linkage structure. When the upper sealing and cutting device rises and falls, it can drive the lower sealing and cutting device to rise and fall in the opposite direction. The operator only needs to control the rise and fall of the upper sealing and cutting device to complete the corresponding action of the lower sealing and cutting device at the same time. During the sealing and cutting process, the two can apply pressure and cut from both the top and bottom directions at the same time, making the seal more secure and the cut more neat.
[0007] The aforementioned novel sealing and cutting machine can be further configured such that: the lifting assembly includes a lifting guide rod disposed between the top plate of the frame and the bottom plate of the frame; the lifting guide rod is provided with a lifting mounting plate between the top plate of the frame and the worktable; both ends of the lifting mounting plate are sleeved on the lifting guide rod; and a lifting drive cylinder connected to the upper sealing and cutting device passes through the center of the lifting mounting plate.
[0008] Using the above technical solution, the lifting guide rod set between the top plate and the bottom plate of the frame provides guidance for the movement of the lifting mounting plate. The two ends of the lifting mounting plate are sleeved on the lifting guide rod, which enables the lifting mounting plate to move smoothly along the guide rod during the lifting process. The lifting drive cylinder passing through the center of the lifting mounting plate is connected to the upper sealing and cutting device to realize the lifting and lowering of the upper sealing and cutting device.
[0009] The aforementioned novel sealing and cutting machine can be further configured such that: the upper sealing and cutting device includes an upper mounting plate disposed at the bottom of the lifting drive cylinder, the two ends of the upper mounting plate are sleeved on the lifting guide rod, the bottom of the upper mounting plate is provided with an upper sealing and cutting head, and a buffer component for buffering during sealing and cutting is provided between the upper mounting plate and the upper sealing and cutting head.
[0010] With the above technical solution, the upper mounting plate is sleeved on both ends of the lifting guide rod and cooperates with the lifting assembly, so that the upper sealing and cutting device can move smoothly along the guide rod during the lifting process. The upper sealing and cutting blade head set at the bottom of the upper mounting plate can directly seal and cut the packaging of the items. The buffer assembly set between the upper mounting plate and the upper sealing and cutting blade head can absorb and disperse the impact force generated when the upper sealing and cutting blade head comes into contact with the packaging of the items, prevent damage to the blade head due to excessive impact force, and extend the service life of the blade head.
[0011] The aforementioned novel sealing and cutting machine can be further configured as follows: the buffer assembly includes a plurality of mounting holes provided in the mounting plate, a buffer column is provided in the mounting hole, a buffer spring is provided at the bottom of the buffer column, an axial mounting groove is provided on the top of the upper sealing and cutting head, a plurality of positioning columns for positioning and mounting the buffer spring are provided in the mounting groove, one end of the buffer spring is sleeved in the buffer column and the other end is sleeved on the positioning column, the upper mounting plate is also provided with a plurality of buffer guide holes for mounting buffer guide rods, and the upper mounting plate and the upper sealing and cutting head are connected by buffer guide rods.
[0012] By adopting the above technical solution, the buffer column and buffer spring installed in the mounting hole cooperate to effectively absorb and disperse the impact force generated when the sealing and cutting action occurs, thus preventing the blade from being damaged by excessive impact force. The connection between the buffer guide hole and the guide rod on the upper mounting plate provides precise guidance for the movement of the upper sealing and cutting blade, enabling the blade to move smoothly along the predetermined trajectory during the sealing and cutting process, further improving the precision and accuracy of sealing and cutting.
[0013] The aforementioned novel sealing and cutting machine can be further configured such that: the lower sealing and cutting assembly includes a lower mounting plate disposed between the worktable and the machine frame base plate, the two ends of the lower mounting plate are sleeved on the lifting guide rod and placed in the placement groove, and the top of the lower mounting plate is provided with a lower sealing and cutting blade head.
[0014] Using the above technical solution, the two ends of the lower mounting plate are sleeved on the lifting guide rod and placed in the placement slot of the worktable, so that it can remain stable during the lifting process and avoid shaking or deviation. The lower sealing and cutting head set on the top of the lower mounting plate cooperates with the upper sealing and cutting head of the upper sealing and cutting device to simultaneously seal and cut the packaging of the items from both the top and bottom.
[0015] The aforementioned novel sealing and cutting machine can be further configured such that: the chain linkage structure includes rotating rollers fixedly disposed at both ends of the lifting mounting plate; both ends of the upper mounting plate and the lower mounting plate are provided with connectors for chain connection; one end of the chain passes around the rotating rollers and is connected to the connector of the upper mounting plate, and the other end is connected to the connector of the lower mounting plate.
[0016] Using the above technical solution, the chain passes around the rotating roller, with one end connected to the connector of the upper mounting plate and the other end connected to the connector of the lower mounting plate. When the lifting mounting plate drives the upper sealing and cutting device to rise and fall under the action of the lifting drive cylinder, the chain can accurately transmit the motion to the lower sealing and cutting device, realizing the reverse synchronous movement of the upper sealing and cutting device and the lower sealing and cutting device.
[0017] The aforementioned novel sealing and cutting machine can be further configured such that: a feeding pusher plate is axially arranged on the surface of the worktable, the feeding pusher plate includes support plates arranged opposite each other, a pusher plate is connected between the support plates, the pusher plate and the support plates are perpendicular to each other, and each support plate is provided with a connecting plate.
[0018] By adopting the above technical solution, the feeding pusher plate axially arranged on the worktable surface, with its structure designed to be perpendicular to the support plate, can form a stable and effective feeding plane. When it is necessary to feed the items, the pusher plate can directly act on the items, pushing them smoothly and accurately to the sealing and cutting position, ensuring the smoothness and efficiency of the feeding process and improving the overall working efficiency of the sealing and cutting machine.
[0019] The aforementioned novel sealing and cutting machine can be further configured such that: both ends of the top plate of the frame are provided with spiral adjusting rods, and the top plate of the frame is provided with an adjusting handle that can rotate the spiral adjusting rods to adjust the lifting mounting plate.
[0020] By employing the above technical solution, the lifting mounting plate can be precisely adjusted by rotating the adjusting handle to control the spiral adjusting rod. In actual sealing and cutting operations, different packaging materials and items may require different sealing and cutting pressures and heights. This adjustment function allows for flexible adjustment of the position of the upper sealing and cutting device, ensuring the effective cooperation between the upper and lower sealing and cutting blades, effectively improving sealing and cutting quality, and guaranteeing a firm seal and neat cuts.
[0021] The beneficial effects of this utility model are as follows: The lifting assembly set on the top plate of the frame can drive the upper sealing and cutting device to rise and fall, while the lower sealing and cutting device is connected to the upper sealing and cutting device through a chain linkage structure. When the upper sealing and cutting device rises and falls, it can drive the lower sealing and cutting device to rise and fall in the opposite direction. The operator only needs to control the rise and fall of the upper sealing and cutting device to complete the corresponding action of the lower sealing and cutting device at the same time. During the sealing and cutting process, the two can apply pressure and cut from both the top and bottom directions at the same time, making the seal more secure and the cut more neat.
