[0081] Workflow: Put the material to be packaged into the hopper 23, place the bag to be used at the bag feeding mechanism 4, check whether each part of the equipment is installed correctly and can operate normally. Start the bag feeding mechanism 4, and the bag feeding mechanism 4 transports the bag from the initial position to the designated position in the body 1, that is, below the hopper 23 and at the tensioning mechanism 3. After the bag is in place, the operator fills the material into the bag through the hopper 23. After the material is filled into the bag, the tensioning mechanism 3 starts to work, and the driving part 32 drives the tensioning part 31 to move vertically to the bag conveying direction, and the tensioning assemblies on both sides of the bag act simultaneously to apply tension to the bag, so that the sealing part of the bag remains flat. After tensioning, the sealing mechanism 5 starts to seal the tensioned bag, completing the packaging process, so that the bag is tensioned before sealing, the sealing part of the bag remains flat, the problem of uneven sealing part is solved, and the sealing quality and appearance are improved.

[0082] As shown in Figure 2 and Figure 3 In this embodiment, the optimized driving part 32 includes:

[0083] The fixed plate 321 has two, which are respectively arranged on the left and right sides inside the groove 2 and located on both sides of the bag;

[0084] The rotating shaft 322 is rotatably arranged on the fixed plate 321, and the tensioning part 31 is fixed on the rotating shaft 322;

[0088] The rack 326 is arranged on the piston rod of the cylinder one 325, and the rack 326 is engaged with the gear 323.

[0089] In the technical solution, the linear motion of the air cylinder 325 is converted into the rotation of the rotating shaft 322 through the meshing transmission of the rack 326 and the gear 323, thereby providing the tensioning member 31 with movement power to realize the tensioning operation on the bag. The air cylinder 325 can accurately control the size and stroke of the output force. Through the transmission of the rack 326 and the gear 323, the tensioning member 31 can stably apply a suitable tensioning force to the bag, ensuring that the sealing part of the bag is flat, and neither too small tensioning force leading to uneven sealing nor too large tensioning force damaging the bag. The two fixed plates 321 are respectively arranged on the left and right sides inside the groove 2, thereby providing the rotating shaft 322 with stable support to ensure the stability of the rotating shaft 322 during rotation. The bracket 324 is used to fix the air cylinder 325, so that the entire driving part 32 is compact in structure and not easy to shake during operation, thereby improving the reliability and service life of the equipment.

After the hopper 23 fills the material into the bag, the control system of the equipment receives the signal of completing bagging and prepares to start the tensioning operation. The control system issues an instruction, the piston rod of the air cylinder 325 starts to extend, drives the rack 326 arranged thereon to move upward, and the gear 323 meshing with the rack 326 starts to rotate. Since the rotating shaft 322 is fixedly connected with the gear 323, the rotating shaft 322 also rotates, and the tensioning member 31 fixed on the rotating shaft 322 moves toward the bag along with the rotation of the rotating shaft 322. The tensioning members 31 on both sides of the bag simultaneously act to apply tensioning force to the bag, so that the sealing part of the bag is gradually tightened and kept flat. When the piston rod of the air cylinder 325 extends to the set position and the tensioning member 31 reaches the predetermined tensioning state, the sealing part of the bag has been flat and tensioned, and is waiting for the next sealing operation. After completing the sealing operation, the piston rod of the air cylinder 325 is retracted, drives the rack 326 to move backward, the gear 323 reversely rotates, and the tensioning member 31 returns to the initial position, thereby preparing for the next tensioning operation. Thus, the movement power is provided for the tensioning member 31 to realize the tensioning operation on the bag, and the size and stroke of the output force can be accurately controlled. Through the transmission of the rack 326 and the gear 323, the tensioning member 31 can stably apply a suitable tensioning force to the bag, ensuring that the sealing part of the bag is flat, and neither too small tensioning force leading to uneven sealing nor too large tensioning force damaging the bag.

[0091] Embodiment 2

[0092] The embodiment provides a desktop bagging and sealing machine, which has the following technical features in addition to the technical solutions of the above embodiments.

[0093] As Figure 1 , Figure 4 and Figure 5 shown, in this embodiment, the optimized bag feeding mechanism 4 includes:

[0094] a through slot 41 is provided on the rear side of the machine body 1;

[0095] a bag outlet slot 42 is provided on the machine body 1, and the bag outlet slot 42 is in communication with the through slot 41 and the groove 2;

[0096] a support plate 43 is provided inside the through slot 41 on both sides;

[0097] a second frame 44 is provided on the support plate 43 by means of bolt connection;

[0098] a transmission shaft 45 is rotatably provided between the two second frames 44, and the transmission shaft 45 has two, located on the upper and lower sides of the second frame 44;

[0099] a feeding roller 46 is provided on the transmission shaft 45, and the two feeding rollers 46 are symmetrically distributed above and below and located behind the bag outlet slot 42;

[0100] a motor 47 is provided outside the machine body 1, and the output shaft of the motor 47 is connected with the transmission shaft 45.

[0101] In this technical solution, the through slot 41 and the bag outlet slot 42 provide a clear path for the delivery of the bag. The through slot 41 is on the rear side of the machine body 1, and the bag outlet slot 42 is in communication with the through slot 41 and the groove 2, so that the bag can be smoothly delivered from the rear side of the machine body 1 to the bagging and sealing work area inside the machine body 1, ensuring the orderliness of the bag feeding process. The motor 47 serves as a power source, and its output shaft is connected with the transmission shaft 45 to drive the transmission shaft 45 to rotate. The feeding roller 46 on the transmission shaft 45 rotates with it, and the feeding rollers 46 symmetrically distributed above and below can clamp the bag and drive it to move along the bag outlet slot 42 to the designated position inside the machine body 1 by friction, realizing the automatic bag feeding function and improving the work efficiency of bagging and sealing.

[0102] Workflow: the bag feeding mechanism 4 at the rear of the fuselage 1 is placed in the initial position of the bag to be transported, the operator starts the device, the motor 47 starts to work, the output shaft of the motor 47 drives the transmission shaft 45 to rotate. Because the feeding roller 46 is arranged on the transmission shaft 45, when the two transmission shafts 45 rotate, the feeding rollers 46 symmetrically distributed above and below will be driven to rotate synchronously. Put one end of the bag between the upper and lower feeding rollers 46, and the friction generated by the rotation of the feeding rollers 46 clamps the bag and transports it forward along the bag outlet slot 42. The bag passes through the through slot 41 and the bag outlet slot 42 in turn, and enters the recess 2 position inside the fuselage 1, that is, the designated area for bagging and subsequent operation. When the bag is transported to the predetermined position, according to the setting of the control system of the device, the motor 47 stops working, and the feeding roller 46 also stops rotating, waiting for the next bagging operation instruction. At this time, the bag can be bagged to realize the automatic bag feeding function and improve the working efficiency of bagging and sealing.

[0103] Example 3:

[0104] This embodiment provides a desktop bagging and sealing machine, in addition to the technical solutions of the above-mentioned embodiments, it also has the following technical features.

[0105] As shown in Figure 1 , Figure 5 and Figure 6 , in this embodiment, the optimized sealing mechanism 5 includes:

[0106] The chute 51 is opened on the left and right sides inside the fuselage 1, and the chute 51 extends forward to the through fuselage 1;

[0107] The sliding plate 52 is slidingly arranged in the chute 51 and extends out of the chute 51;

[0108] The sealer 53 is arranged between the front sides of the two sliding plates 52;

[0109] The electric push rod 54 is arranged inside the fuselage 1, and the piston rod of the electric push rod 54 is connected with the sliding plate 52;

[0110] The heating element 55 is arranged inside the sealer 53;

[0111] The pressing plate 56 is arranged at the lower part of the bag outlet slot 42 and located on the opposite side of the sealer 53. The bag is located in front of the pressing plate 56, and the sealer 53 moves towards the pressing plate 56 to seal the bag.

[0112] In the technical solution, the sliding grooves 51 formed on the left and right sides inside the machine body 1 provide a guiding effect for the sliding of the sliding plate 52, so that the sliding plate 52 can move stably along a predetermined direction, thereby ensuring that the movement track of the sealing device 53 connected with the sliding plate 52 is accurate during the sealing process, and ensuring the accurate operation on the sealing position of the bag. The electric push rod 54 serves as a power device, the piston rod of which is connected with the sliding plate 52, and the sliding plate 52 is driven to slide in the sliding groove 51 through the extension and retraction of the electric push rod 54, so that the sealing device 53 can move towards the pressing plate 56 or retreat. When the sealing device 53 moves towards the pressing plate 56, it contacts and applies pressure to the bag located in front of the pressing plate 56, and cooperates with the heating element 55 inside the sealing device 53 to realize the hot-press sealing of the bag, thereby ensuring the sealing property of the package. The pressing plate 56 is arranged below the bag outlet groove 42 and opposite to the sealing device 53, and can provide a supporting surface for the bag during the sealing process, so that the bag can remain flat when subjected to the pressure and heat of the sealing device 53, which helps to improve the quality and effect of the sealing and prevent wrinkles or loose sealing at the sealing position.

[0113] Work flow: initially, the sealing device 53 and the pressing plate 56 are kept at a certain distance, and the heating element 55 is in a preheating or off state (waiting for a work instruction). The bag conveying mechanism 4 conveys the bag to the bag outlet groove 42 and to the specified position in front of the pressing plate 56, and waits for the sealing operation; the equipment control system issues an instruction to start the heating element 55 inside the sealing device 53, so that it is heated to a suitable sealing temperature. When the heating element 55 reaches the set temperature, the piston rod of the electric push rod 54 extends and retracts, pushing the sliding plate 52 to slide in the sliding groove 51 towards the pressing plate 56, and the sliding plate 52 drives the sealing device 53 to move towards the pressing plate 56, and the sealing device 53 gradually approaches the bag. When the sealing device 53 contacts the bag, it continues to apply pressure, so that the bag is squeezed between the sealing device 53 and the pressing plate 56. At this time, the heat generated by the heating element 55 is transferred to the bag, so that the sealing part of the bag is heated and fused together, and the sealing process is completed. After the sealing is completed, the piston rod of the electric push rod 54 is retracted, driving the sliding plate 52 and the sealing device 53 to retreat to the initial position; the heating element 55 stops working or enters a heat preservation state, waiting for the next sealing task, so as to realize the hot-press sealing of the bag and ensure the sealing property of the package.

During the bagging process, when the bagging operation is not performed, cover plate 63 covers the discharge port of hopper 23 to prevent the material from accidentally spilling; when the bagging is needed, cover plate 63 can be opened as needed to make the material flow out smoothly, avoiding the waste of the material and ensuring the accuracy of the bagging. When cover plate 63 is opened, it can open the bag, so that the bag opening remains in an open state, facilitating the smooth filling of the material into the bag, reducing the operation of manually opening the bag, and improving the bagging efficiency. Cylinder two 69 is used as a power source, through the extension and retraction movement of the piston rod thereof, cover plate 63 is driven to rotate through connecting frame 610 and connecting shaft 65, automatic control of the opening and closing of the discharge port of hopper 23 is realized, manual intervention is reduced, and the production efficiency and the consistency of the operation are improved.

[0128] Workflow: cover 63 tightly cover the discharge port of the hopper 23, to prevent material leakage. At this time the first rotating rod 62, the second rotating rod 67 are in a relatively static state, each component remains stable. Bag conveying mechanism 4 will be sent to the bag under the hopper 23 appropriate position, the control system sends instructions, the piston rod of cylinder two 69 extension, push connecting frame 610 movement, connecting frame 610 drive connecting shaft 65 movement, because the connecting shaft 65 is set in the fixed frame 64, fixed frame 64 is connected with the cover 63, so with the movement of connecting shaft 65, cover 63 drive first rotating rod 62 around the branch plate 61 rotation, the discharge port of the hopper 23 is gradually opened, the material began to fall. At the same time, the cover 63 opened below the bag to open, facilitate the material into the bag, the material from the hopper 23 discharge port flow into the bag opened by the cover 63, the operator can according to the actual bagging situation, through the control system to adjust the extension length of the piston rod of cylinder two 69, in order to control the discharge amount. When the bagging is completed, the control system sends instructions again, the piston rod of cylinder two 69 extension, connecting frame 610 pull connecting shaft 65 reverse movement, so that the cover 63 around the first rotating rod 62 turn back, re cover the discharge port of the hopper 23, complete a discharge control process, waiting for the next bag and bagging instructions.

[0129] Example 5:

[0130] This embodiment provides a desktop bagging and sealing machine, in addition to including the technical solutions of the above embodiments, also has the following technical features.

[0131] As Figures 1-3 shown in this embodiment, the optimization also includes adjusting mechanism 7, adjusting mechanism 7 includes:

[0132] The installation guide rail 71 is arranged on the mounting plate 21;

[0133] The waist hole 72 is provided on the installation guide rail 71, and the waist hole 72 has a plurality of and is uniformly distributed along the length direction of the installation guide rail 71;

[0134] The slider 73 is slidably arranged on the installation guide rail 71, and the slider 73 is connected with the waist hole 72 by means of bolt connection, and the fixed plate 321 is arranged on the front side of the slider 73, so as to adjust the position of the tensioning piece 31 according to the size of the bag.

[0135] In the actual packaging operation, the bag size is various, and the setting of the adjusting mechanism 7 allows the position of the tensioning piece 31 to be flexibly changed according to the size of the bag. By moving the position of the sliding block 73 on the mounting rail 71, the fixed plate 321 and the tensioning piece 31 fixed on the fixed plate 321 are synchronously moved, so that the tensioning piece 31 is accurately positioned, ensuring that bags of different sizes can be effectively tensioned before sealing, improving the applicability of the equipment to various packaging needs. The plurality of waist holes 72 uniformly distributed on the mounting rail 71 are connected with the sliding block 73 through bolts. This design enables the operator to conveniently loosen the bolts, slide the sliding block 73 along the mounting rail 71, tighten the bolts after adjusting to the appropriate position, and fix them. The whole adjustment process is simple to operate and does not require complex tools or professional skills, saving equipment adjustment time and improving work efficiency. Accurate adjustment of the position of the tensioning piece 31 can make the tensioning assembly apply uniform and appropriate tension to both sides of bags of different sizes. It ensures that the sealing part of the bag can remain flat after tensioning, thereby ensuring the stability and consistency of the sealing quality and avoiding uneven sealing effect caused by different bag sizes.

[0136] Workflow: After the operator gets the bag to be packaged, he / she judges whether the size of the bag is different from the size of the previously packaged bag according to experience or actual measurement, and determines whether the position of the tensioning piece 31 needs to be adjusted. Find the bolt connected to the sliding block 73, loosen the bolt using the corresponding tool (such as a wrench), and remove the fixed state between the sliding block 73 and the mounting rail 71, so that the sliding block 73 can slide freely on the mounting rail 71. Manually push the sliding block 73 and move it along the length direction of the mounting rail 71. Observe the relative position of the tensioning piece 31 fixed on the front side of the fixed plate 321 and the bag during the movement of the sliding block 73, and estimate the appropriate position of the tensioning piece 31 according to the width of the bag. When the sliding block 73 moves to a position where the tensioning piece 31 can effectively tension the bag in the subsequent work, stop sliding. Tighten the bolt again using the tool to fix the sliding block 73 and the mounting rail 71 together through the waist hole 72, so as to ensure that the sliding block 73 does not shift during the operation of the equipment. After the adjustment is completed, start the equipment for normal bagging, tensioning, sealing and other operations. When different sizes of bags are encountered subsequently, repeat the above steps and adjust the position of the tensioning piece 31 according to the size of the new bag.

[0137] As shown in Figure 1 and Figure 5 In this embodiment, the optimization further includes a control module 8 electrically connected with the first cylinder, the motor 47 and the electric push rod 54, for controlling the tensioning action, the feeding action and the sealing action to be performed in sequence.

[0138] In the technical solution, the control module 8 is electrically connected with the first cylinder, the motor 47 and the electric push rod 54, can accurately plan the sequence of the tensioning action, the feeding action and the sealing action, avoids the conflict and confusion between the actions, and ensures that the equipment packaging process is carried out in an orderly manner. For example, only after the feeding action is completed and the bag is accurately positioned, the control module 8 triggers the tensioning action, and then starts the sealing action, to ensure that each link is closely connected. With accurate control of the actions, the control module 8 reduces manual intervention and waiting time, and realizes automatic operation of the equipment. The motor 47 quickly and stably transports the bag, the first cylinder timely tensions the bag, and the electric push rod 54 efficiently completes the sealing, the whole process is efficient and smooth, and the packaging output per unit of time is greatly improved. Strictly controlling the actions of each component according to the preset sequence can effectively avoid mechanical damage to the equipment caused by uncoordinated actions. For example, prevent the tensioning mechanism 3 or the sealing mechanism 5 from acting in advance when the motor 47 does not stop feeding, to damage the equipment components, thereby prolonging the service life of the equipment and ensuring long-term stable operation of the equipment. The operator can easily set the parameters of each action, such as the speed of the motor 47, the tensioning force of the first cylinder, the stroke and speed of the electric push rod 54, etc., through the operation interface (such as the control panel, touch screen, etc.) of the control module 8, to adapt to different packaging materials, bag sizes and sealing requirements, so that the equipment has high operation flexibility.

[0139] Workflow: The operator starts the equipment, and after the control module 8 receives the start packaging instruction issued by the operator, first sends a signal to the motor 47, and the motor 47 starts to operate to drive the feeding roller 46 to transport the bag along the predetermined path to the bagging position. In this process, the control module 8 monitors the running state of the motor 47 in real time to ensure that the feeding speed is stable and the bag is transported to the position.

[0140] When the control module 8 detects through the sensor that the bag has accurately arrived at the bagging position and the bagging is completed, it sends an instruction to the first cylinder. The first cylinder starts, the piston rod extends, and through the transmission of the rack 326 and the gear 323, drives the tensioning piece 31 to perform the tensioning operation on the bag. The control module 8 accurately controls the output force of the first cylinder according to the preset tensioning force parameter, to ensure that the bag is uniformly and moderately tensioned.

[0141] After the tensioning action is completed and the control module 8 confirms that the bag has been tensioned to the position, it sends a start signal to the electric push rod 54. The electric push rod 54 pushes the sliding plate 52, so that the sealer 53 moves towards the pressure plate 56 to seal the tensioned bag. The control module 8 controls the temperature and heating time of the heating element 55 at the same time to ensure the sealing quality. After the sealing is completed, the electric push rod 54 drives the sealer 53 to retreat to the initial position.

[0142] After completing a sealing operation, the control module 8 triggers the motor 47 again to perform the feeding action, and repeats the above packaging process to continuously perform the bagging, tensioning and sealing operations until the operator stops the equipment operation. During the entire process, if an abnormal situation (such as bag blockage, component failure, etc.) occurs, the control module 8 will immediately receive the signal feedback from the sensor, stop the relevant action, and issue an alarm to prompt the operator to handle it.

[0143] The embodiments of the present application are described above in conjunction with the drawings, and the embodiments and features in the present application can be combined with each other without conflict, and the present application is not limited to the specific embodiments described above, which are only illustrative and not restrictive. Those skilled in the art can make many forms under the inspiration of the present application without departing from the scope of the present application and the protection scope of the claims, and all of them belong to the protection of the present application.
