Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology, specifically a horizontal sealing packaging machine. Background Technology

[0002] The sealing mechanism of a packaging machine is a part of the packaging machine. After the plastic film passes through the forming device to form a bag, it needs to be sealed by the sealing mechanism. The bag sealing mechanism includes a longitudinal sealing mechanism and a transverse sealing mechanism. The longitudinal sealing mechanism uses a pair of vertical heating blocks to close and form a vertical seal on the film inside. The transverse sealing mechanism uses a pair of horizontal heating blocks to close and form a transverse seal on the film inside.

[0003] In the existing technology, traditional horizontal sealing mechanisms usually adopt a fixed speed drive method. The movement rhythm of the cutter is controlled by a single motor, and its speed is preset before the equipment is started and remains fixed. It cannot be adjusted in real time according to the actual conveying speed (film speed) of the packaging film.

[0004] Because the blade speed and film speed cannot be dynamically matched, slight speed fluctuations during the packaging film conveying process (such as unstable film feeding motor speed, differences in film feeding amount due to changes in film roll diameter, etc.) will cause the cutting timing of the cutter to deviate from the position of the packaging film, easily resulting in uneven cutting, sealing wrinkles, uneven cutting, etc., leading to a decrease in yield. In addition, the sealing pressure cannot be adjusted flexibly and evenly, which will cause some areas of the packaging film to be sealed too tightly, resulting in film damage, while other areas to be sealed too loosely, resulting in leaks, seriously affecting packaging quality. The cumbersome adjustment of the blade holder spacing will increase the operation time when changing materials or packaging specifications, reducing production efficiency.

[0005] In light of this, we have introduced a horizontal sealing packaging machine. Utility Model Content

Inside the side frame is a central sealing mechanism for pressing the bags. The horizontal sealing mechanism utilizes cylinder A, a cutter, and a knife-seal adjustment pad. Cylinder A provides power, driving the cutter to move up and down, while the knife-seal adjustment pad adjusts the sealing position and pressure, ensuring precise and stable sealing. With the assistance of cylinder A, the cutter horizontally cuts the sealed bag, separating the continuous bag body into individual packaged products.

[0013] Preferably, a press bearing is connected between the rotating shaft and gears A and B; the press bearing is a high-precision ball bearing with radial clearance controlled within the range of 0.01 to 0.03 mm, which can reduce radial runout when the rotating shaft rotates, ensure the smoothness of gear meshing, and at the same time reduce the coefficient of friction to 0.001-0.003, thus extending the service life of the components.

[0014] Preferably, the surfaces of the two sets of pressing frames are provided with gap adjustment blocks, and the tops of the two sets of pressing frames are provided with protective covers. The gap adjustment blocks are provided with scale markings, which can accurately control the distance between the two sets of pressing frames according to the thickness of the packaging material. The protective covers are made of transparent acrylic material, which not only facilitates observation of the internal working status, but also effectively isolates high-temperature components from operators to prevent accidental burns.

[0015] Preferably, the frame and side frame are connected to support legs at the bottom, and the top of the frame is equipped with a touch display. One side of the side frame is equipped with a connecting frame, and the surface of the connecting frame is equipped with a bagging adjustment handle.

[0017] Preferably, the side frame is provided with a positioning box, the surface of which is provided with a paper feeding roller. A centering handle and a fixing handle are respectively provided on the side surface of the positioning box, and the surface of the positioning box is also provided with a paper feeding roller opening and closing handle. The surface of the paper feeding roller is made of rubber with a Shore hardness of 60-70 HA, which ensures sufficient friction to drive material conveying while preventing scratches on the packaging surface. The adjustment range of the centering handle is...

[0018] ±50mm, in conjunction with the guide rail inside the positioning box, allows for horizontal centering adjustment of the paper feed roller; the fixing handle adopts a butterfly nut design with a tightening torque of 20~30N·m, ensuring a stable position after adjustment; the operating force of the paper feed roller opening and closing handle is ≤50N, making it easy for operators to quickly switch the paper feed roller on and off.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] (1) The servo system detects the linear speed of the pressing wheel (film speed) in real time and automatically adjusts the servo speed of the cutter to achieve dynamic synchronous sealing and cutting. The cutter speed and film speed are matched in real time. The cutter moves precisely under the drive of the cylinder and can perfectly match the rhythm of the packaging film conveying, achieving continuous and stable transverse cutting. It accurately separates the continuous bag into individual finished products, greatly reducing errors in the sealing and cutting process and improving the overall packaging efficiency. At the same time, the stacked design of the knife seal adjustment pad can flexibly adjust the knife seat spacing. Combined with the symmetrical structure of the upper and lower knife holders, it ensures uniform sealing pressure and improves sealing quality.

[0021] (2) The middle sealing and pressing mechanism lays a good foundation for subsequent horizontal sealing through the coordinated operation of two sets of pressing frames. The meshing transmission of gear A and gear B ensures the synchronous rotation of the shaft and the passive pressing wheel, so that the edge of the packaging film can be smoothly transported to the heating element for longitudinal heat sealing. The gap adjustment block can flexibly adjust the spacing of the pressing wheel according to the characteristics of the packaging material, ensuring that packaging films of different thicknesses can obtain a suitable pre-sealing effect, thereby improving the sealing and stability of the packaging.

[0022] (3) The heat insulation pad can effectively block the heat transfer from the heating element to the pressing frame, avoid the deformation or aging of mechanical parts due to long-term exposure to high temperature environment, reduce the wear and tear and failure probability of parts, extend the overall service life of the equipment, reduce the maintenance cost and downtime frequency of the equipment, and ensure the continuity of production.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed", "equipped with", "sleeved with", "connected", etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0032] Please see Figure 1-6 This utility model provides a technical solution: a horizontal sealing packaging machine, including: a frame 1 and a side frame 4 forming a key support structure, a processing cavity 5 opened at the top of the frame 1, in which a horizontal sealing mechanism 6 is precisely installed, while the side frame 4 is stably set on the side of the frame 1. The two are assembled together to provide a solid foundation for the efficient operation of the packaging machine.

[0033] In the packaging process, the horizontal sealing mechanism 6 plays a crucial role in horizontal sealing and cutting. Its core components include a lower knife holder 63 located within the processing chamber 5, with a lower knife seat 64 tightly connected to the top of the lower knife holder 63. An upper knife seat 65 is securely positioned on top of the lower knife seat 64, and an upper knife holder 62 is connected to the upper knife seat 65. A cylinder A61 is precisely mounted on top of the upper knife holder 62 via a positioning bracket, serving as a power source to provide stable and powerful driving force for the entire horizontal sealing action. A cutter 66 is connected to the output end of the cylinder A61. When the cylinder A61 provides power, the cutter 66 can move up and down precisely and quickly in the vertical direction. A knife sealing adjustment pad 68 is installed between the upper knife holder 62 and the upper knife seat 65, which can adjust the sealing position. The device allows for precise fine-tuning and can reasonably adjust the sealing pressure according to different packaging materials and process requirements, ensuring a strong and aesthetically pleasing sealing effect. This guarantees the accuracy and stability of each sealing and cutting operation. When a continuous bag passes through this point, cylinder A61 drives the cutter 66 downward. After reaching the predetermined position, the cutter 66 performs a transverse cut on the bag that has completed the middle sealing and pressing, accurately separating the continuous bag into individual packaging products, achieving efficient packaging material sorting. The brackets 67 connected to both sides of the lower cutter holder 63 provide reliable support and fixation for the entire transverse sealing mechanism 6, ensuring its stability, reducing vibration and displacement, and guaranteeing sealing and cutting accuracy during frequent operations of the transverse sealing mechanism 6.

[0034] The center-sealing and pressing mechanism 7, located inside the side frame 4, is responsible for the crucial task of longitudinally pressing the bag. The center-sealing and pressing mechanism 7 includes two sets of pressing frames 76, each with a rotating shaft 74 installed inside. Both ends of the rotating shaft 74 pass through the pressing frame 76, achieving stable support and flexible rotation. A gear A78 is connected to the surface of one set of rotating shafts 74, and a gear B715 is connected to the surface of the other set of rotating shafts 74. Gears A78 and B715 mesh with each other. This gear transmission structure ensures that the two sets of rotating shafts 74 rotate synchronously and stably. The heating element 73 connected to the other end of the rotating shaft 74 can heat up rapidly during equipment operation, providing the necessary heat for the sealing and pressing of the bag, softening the packaging material and facilitating the pressing. The passive pressing wheel 71 connected to the bottom of the other end of the rotating shaft 74, in conjunction with the heating element 73 and the pressing structure above, presses the bag tightly during bag conveying, ensuring the quality of the sealing. The heat insulation pad 75 set at the bottom of the pressing frame 76 can effectively prevent heat from being transferred downwards, reduce heat loss, and avoid thermal impact on the equipment components below.

[0035] The support rod 711 on the side of the pressing frame 76, together with the fixed rod 712 connected to the side, forms a stable support structure, providing additional lateral support force for the pressing frame 76. The opening and closing cylinder 713 connected to one side of the fixed rod 712 can precisely control the opening and closing action of the pressing frame 76. According to the packaging process requirements, the pressing timing and pressure can be flexibly adjusted. The pneumatic pressure gauge 714 connected to one side of the opening and closing cylinder 713 through a fixing component can monitor and display the air pressure in the cylinder in real time, which is convenient for operators to adjust the pressure according to actual needs, ensuring the consistency and stability of the pressing effect.

[0036] The press bearing 710 connecting the shaft 74 to gears A78 and B715 greatly reduces friction during rotation, making gear transmission smoother and more stable, reducing energy loss, improving equipment operating efficiency, and extending equipment service life.

[0037] The gap adjustment blocks 77 on the surfaces of the two sets of pressing frames 76 can precisely adjust the gap distance between the two sets of pressing frames 76 according to the thickness of different packaging materials and pressing requirements, ensuring the accuracy of the pressing effect. The protective covers 79 on the top of the two sets of pressing frames 76 can prevent operators from accidentally coming into contact with the high-temperature heating element 73 and the moving parts, ensuring personnel safety; on the other hand, they can also prevent external debris from entering the pressing mechanism and affecting the normal operation of the equipment.

[0038] Regarding the ease of operation and adjustment of the entire machine, the support legs 2 connected to the bottom of the frame 1 and the side frame 4 provide stable support for the equipment, ensuring its stability during operation. The touch display 3 set on the top of the frame 1 has an intuitive and convenient human-machine interface. Operators can quickly set and adjust the operating parameters of the equipment, such as horizontal sealing temperature, middle sealing pressure, and packaging speed, through the touch display 3. At the same time, they can view the operating status of the equipment and fault alarm information in real time, which greatly improves the ease of operation and intelligence of the equipment.

[0039] The connecting frame 12 on one side of the side frame 4 has a bag-forming adjustment handle 11 mounted on its surface, which can be used to fine-tune the size and shape of the formed packaging bag to adapt to the packaging needs of different products. The swing rod 13 rotatably connected to the bottom of the connecting frame 12, and the adjustment handle 14 on the surface of the swing rod 13, can further finely adjust the conveying angle and tension of the packaging material to ensure that the packaging material maintains a stable and accurate position during the conveying process and improves the packaging quality.

[0040] The paper feeding roller opening and closing handle 10 on the surface of the side frame 4 allows operators to easily control the start and stop of the paper feeding roller and its contact status with the packaging material. During equipment debugging, packaging material replacement, or in case of malfunction, the paper feeding roller can be quickly opened and closed. The pressure roller fine-tuning handle 9 on the side of the paper feeding roller opening and closing handle 10 allows for minor adjustments to the pressure of the pressure roller, ensuring that the packaging material is evenly and stably pressed during transport, preventing slippage or uneven transport. The angle adjustment handle 8 on the surface of the side frame 4, located above the center sealing and pressing mechanism 7, allows for adjustment of the tilt angle of the center sealing and pressing mechanism 7 to adapt to different packaging processes and product characteristics, ensuring the reliability of the center sealing and pressing effect.

[0041] The positioning box 16 is located on the side of the side frame 4, and the paper feeding roller 15 is mounted on its surface. It is used to convey and guide the packaging material. The centering handle 17 and the fixing handle 18 are respectively located on the side of the positioning box 16, which can precisely adjust the position of the paper feeding roller 15 to ensure that the packaging material is always kept in the center position during the conveying process and avoids deviation. The paper feeding roller opening and closing handle 19 is also located on the surface of the positioning box 16, which makes it convenient for operators to control the contact and separation between the paper feeding roller 15 and the packaging material, providing a convenient control method during equipment maintenance, packaging material replacement and other operations.

[0042] Specifically, during use, the central sealing and pressing mechanism 7 is installed inside the side frame 4. During the packaging process, it undertakes the pre-sealing task of the packaging film, preparing for the subsequent horizontal sealing. The rotating shafts 74 in the two sets of pressing frames 76 rotate synchronously through the meshing of gears A78 and B715. When the passive pressing wheel 71 rotates with the rotating shaft 74, it will smoothly transport the edge of the packaging film to the heating element 73 to complete the longitudinal heat sealing. The temperature of the heating element 73 can also be adjusted within the range of 0-399℃, and the temperature control accuracy is ±1℃, which can meet the heat sealing requirements of different packaging films. The gap adjustment block 77 can precisely adjust the distance between the two passive pressing wheels 71 to adapt to packaging materials of different thicknesses.

[0043] The heat insulation pad 75 is made of high-temperature resistant ceramic material with a thickness of 5mm. It can effectively block the heat conduction from the heating element 73 to the pressing frame 76, keeping the temperature of the pressing frame 76 below 50℃. This prevents the mechanical parts from deforming due to high temperature and ensures the stable operation of the equipment. When the equipment is running, the middle sealing temperature is adjusted through an independent temperature control channel. This channel is completely independent of the horizontal sealing temperature control channel and does not interfere with each other. The temperature can be set separately according to the different process requirements of the middle sealing and horizontal sealing to form a precise match and further improve the quality of packaging.

[0044] As the core execution component of packaging forming, the horizontal sealing mechanism 6 operates around the logic of "precise sealing - stable cutting". Each link has precise coordination and control. When the material to be packaged enters the processing chamber 5 along with the packaging film, the cylinder A61 will quickly receive the instruction from the intelligent control system. The cylinder A61 adopts high-precision pneumatic control, and its output end extension and retraction movement has strict stroke control, which can precisely drive the cutter 66 to complete the up and down movement. The movement error can be controlled within 0.1mm.

[0045] The knife seal adjustment pad 68 between the upper knife holder 62 and the upper knife seat 65 adopts a special stepped design of superimposed copper sheets. Operators can change the knife seat spacing by increasing or decreasing the number of copper sheets according to the specific thickness and material of the packaging film, thereby achieving graded pressure adjustment. In order to ensure that the sealing surface is evenly stressed, the carbon paper indentation method is also used for detection. By observing the clarity and uniformity of the indentation, it is judged whether the pressure is appropriate, and then precise adjustments are made to ensure that the stress on every part of the sealing surface is consistent.

[0046] The lower blade holder 63 is firmly fixed in the processing cavity 5 by the brackets 67 on both sides. The connection between the brackets and the processing cavity 5 is made of high-strength bolts to ensure that there will be no loosening when the equipment is running at high speed. The lower blade holder and the upper blade holder 62 form a perfect symmetrical structure. This symmetrical design can ensure the force balance during sealing and cutting. When the upper blade holder 65 and the lower blade holder 64 are engaged, the heating element 73 integrated inside the blade holder will heat seal the packaging film according to the set temperature (0-399℃). At the same time, the cutter 66 completes the transverse cutting under the drive of the cylinder A61. It is worth noting that the blade speed is matched with the film speed in real time through a dual closed-loop system. The servo motor can detect the linear speed of the active pressing wheel in real time, with a detection frequency of up to 1000 times per second. Then, the detected signal is transmitted to the control system to automatically adjust the servo speed of the cutter. The system supports step fine adjustment of 0.01% within the range of ±20%, ensuring that the synchronization accuracy between the blade speed and the film speed is controlled within ±1%, effectively avoiding problems such as packaging film damage or insecure sealing caused by speed mismatch.

[0047] The three-dimensional positioning system further improves the accuracy of sealing. The knife seal lifting motor can be precisely controlled through the touch display 3 to achieve height adjustment, so that the meshing center can be accurately aligned with the horizontal center of the product. The adjustment accuracy can reach 0.02mm. The independent left and right knife seat angle adjustment function can complete phase correction, which can compensate for the small errors caused by mechanical installation, avoid sealing offset, and ensure the accuracy of sealing position.

[0048] In this invention, the automated operation of the equipment relies on the close collaboration of multiple sensors and actuators. The bag-forming opening photoelectric sensor uses a high-precision optical sensor, which can detect the position of the material in real time with a detection accuracy of up to 0.1mm. When the material position deviation exceeds 3mm, the photoelectric sensor will immediately transmit a signal to the control system, triggering the cutter to pause and restart after a delay. At the same time, it will work with the three-dimensional positioning system to make adjustments and reduce the product damage rate.

[0049] The color mark tracking photocell identifies positioning marks on the packaging film with an accuracy of ±2mm and a recognition speed of up to 500 times per second. It can quickly and accurately find the positioning marks. The automatic bag length measurement function automatically determines the bag length by detecting the color mark spacing when changing film rolls. The whole process does not require manual intervention, reducing the film change and debugging time from 30 minutes in traditional equipment to less than 5 minutes, thus improving production efficiency.

[0050] The temperature-speed linkage module is key to ensuring sealing quality. When the packaging speed increases, the temperature controller will automatically compensate the heating temperature according to the speed change, with a compensation accuracy of ±0.5℃. This avoids poor sealing caused by shortened film passage time. The dual independent temperature control channels ensure that the longitudinal and transverse sealing temperatures do not interfere with each other, and can meet the different temperature requirements of longitudinal and transverse sealing respectively, adapting to complex packaging process needs.

[0051] The servo system detects the linear speed (film speed) of the pressing wheel in real time and automatically adjusts the servo speed of the cutter 66 to achieve dynamic synchronous sealing and cutting, and match the cutter speed and film speed in real time.

[0052] In addition, the intelligent control system also has a fault self-diagnosis function, which can monitor the operating status of the equipment in real time. When a fault is detected, the fault code and fault cause will be displayed on the touch display 3 immediately, and an alarm signal will be issued, which will facilitate maintenance personnel to quickly troubleshoot the fault and reduce the downtime of the equipment.

[0053] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
