Description

Technical Field

[0001] The invention relates to the technical field of packaging equipment, and in particular to a bag clamping and moving device and a bulk noodle packaging machine. Background Art

[0002] The packaging of bulk noodles is generally achieved through a bulk noodle packaging machine. Existing bulk noodle packaging machines generally include a silo, a bag loading device and a bag supporting device. The lower part of the silo is provided with a feeding port for putting noodles into a packaging bag located below the feeding port, and the bag supporting device is located below the feeding port; the bag loading device includes two supporting arms, which can open the bag opening in the length direction and drive the packaging bag to rotate after opening so that the bag opening is covered on the bag supporting device; the bag supporting device includes two supporting plates and pressing plates corresponding to the two supporting plates. After the bag opening is covered, the supporting plates can open the two long sides of the bag opening, and the pressing plates press the long sides of the bag opening against the supporting plates. At this time, the bag opening of the packaging bag is open and clamped on the bag supporting device, and then noodles can be put into the packaging bag.

[0003] In order to improve the sealing quality of the packaging bag, the bulk noodle packaging machine is generally provided with a bag clamping moving device, which is movably mounted on the packaging machine frame, and includes a base and two clamping mechanisms mounted on the base, and the two clamping mechanisms are arranged at intervals in a direction perpendicular to the arrangement of the two support plates, and the two clamping mechanisms clamp the two ends of the length direction of the bag mouth of the packaging bag when the packaging bag is filled with noodles and is still pressed on the support plate by the pressing plate, and then when the pressing plate releases the packaging bag, the bag clamping moving device sends the packaging bag filled with noodles to the sealing device for sealing, and before the sealing device heat-seals the packaging bag, the bag clamping moving device will not release the packaging bag, so the sealing part of the packaging bag is relatively flat after sealing. For example, a bulk noodle bagging automatic packaging machine recorded in the invention patent application document with application publication number CN110386305A includes the above-mentioned bag clamping moving device.

[0004] Although the above-mentioned automatic packaging machine for bulk noodle bagging can complete the automatic packaging of bulk noodles and the sealing part of the packaging bag is relatively flat, when the noodles fall into the packaging bag from the silo, a small amount of noodles will not fall smoothly into the bottom of the packaging bag, but will lean on the inner side of the packaging bag, and the upper part of the noodles leaning on the inner side of the packaging bag will extend to the sealing part of the packaging bag. This will cause this part of the noodles to be clamped at the sealing part of the packaging bag when the packaging bag is subsequently heat-sealed, which will cause the sealing of the packaging bag to fail. Summary of the invention

[0005] The object of the present invention is to provide a bag clamping and moving device for solving the problem in the prior art that the sealing of the packaging bag may fail due to part of the noodles being clamped at the sealing part of the packaging bag when packaging bulk noodles; the present invention also provides a bulk noodle packaging machine using the above-mentioned bag clamping and moving device.

[0006] The bag clamping and moving device provided by the present invention adopts the following technical solutions:

[0007] The bag clamping and moving device comprises:

[0008] Base;

[0009] There are two clamping mechanisms, both mounted on the base, and the two clamping mechanisms are arranged opposite to each other, and are used to clamp the two ends of the bag opening of the packaging bag in the length direction after the noodles are filled in the packaging bag;

[0010] The pushing mechanism is installed on the base and includes a pushing piece, which can be relatively close to or away from the two clamping mechanisms in a direction perpendicular to the length direction of the bag opening of the packaging bag;

[0011] The inference piece is provided with an inference portion, which corresponds to the upper side or lower side of the portion of the packaging bag clamped by the clamping mechanism, so that the packaging bag can be pushed laterally when the inference piece is relatively close to the clamping mechanism.

[0012] The beneficial effect of the bag clamping and moving device provided by the present invention is that an inference mechanism is provided in the bag clamping and moving device, and the inference piece in the inference mechanism can be relatively close to the two clamping mechanisms in a direction perpendicular to the length direction of the bag opening of the packaging bag. With such an arrangement, when the two clamping mechanisms clamp the packaging bag, the inference portion on the inference piece can laterally push the upper side or the lower side of the portion of the packaging bag clamped by the clamping mechanism, thereby inferring the noodles leaning against the bag opening of the packaging bag. The noodles leaning against the bag opening of the packaging bag will fall into the packaging bag after being inferred, thereby solving the problem of the noodles leaning against the bag opening of the packaging bag causing the sealing of the packaging bag to fail.

[0013] Furthermore, the inference mechanism also includes a linear action mechanism for driving the inference member to move, and the inference member is fixed on the movable end of the linear action mechanism. The inference member is only used to infer the noodles leaning against the bag mouth of the packaging bag. The structure is generally simple and the texture is light, which is convenient for controlling its movement. The clamping mechanism is heavy and has to drive the packaging bag containing the noodles, which is not easy to drive. Therefore, a linear action mechanism is set to drive the inference member to move so as to achieve the relative approach and distance between the inference member and the two clamping mechanisms. The requirements for the linear action mechanism are relatively low, which can reduce the cost of the bag clamping moving device. In addition, compared with setting a linear action mechanism to drive the inference member to move, the structural complexity of the bag clamping moving device can be reduced by setting a linear action mechanism to drive the two relatively arranged clamping mechanisms.

[0014] Furthermore, the inference piece is an L-shaped plate whose length extends in the relative direction of the two clamping mechanisms, including a horizontal plate and a vertical plate perpendicular to each other, the vertical plate is fixedly connected to the movable end of the linear action mechanism, and the horizontal plate constitutes the inference part of the inference piece. The inference piece of this structural form has a simple structure and is easy to be fixedly connected to the movable end of the linear action mechanism.

[0015] Furthermore, the clamping mechanism has a clamping arm for clamping the packaging bag, and the horizontal plate corresponds to the lower side of the portion of the packaging bag clamped by the clamping arm. After the inference mechanism is installed on the base, the upper surface of the horizontal plate is close to the lower side of the clamping arm. When the clamping arm of the clamping mechanism clamps the packaging bag, the noodles leaning against the bag opening of the packaging bag are clamped by the portion of the packaging bag at the same height as the clamping arm. Because the noodles have a certain toughness, the closer the inference portion is to its clamped position, the easier it is to infer the noodles.

[0016] Alternatively, the clamping mechanism has a clamping arm for clamping the packaging bag, the horizontal plate corresponds to the upper side of the portion of the packaging bag clamped by the clamping arm, and after the inference mechanism is installed on the base, the lower surface of the horizontal plate is close to the upper side of the clamping arm. When the clamping arm of the clamping mechanism clamps the packaging bag, the noodles leaning against the bag opening of the packaging bag are clamped by the portion of the packaging bag at the same height as the clamping arm. Because the noodles have a certain toughness, the closer the inference portion is to its clamped position, the easier it is to infer the noodles.

[0017] Furthermore, the dimension of the inference part of the inference piece in the relative direction of the two clamping mechanisms is equal to the length dimension of the packaging bag. This arrangement facilitates the comprehensive inference of the noodles leaning against the inner side of the packaging bag.

[0018] The bulk noodle packaging machine provided by the present invention adopts the following technical solutions:

[0019] The bulk noodle packaging machine includes:

[0020] frame;

[0021] The silo is mounted on the frame and has a material drop opening;

[0022] The bag support device is installed on the frame and is located at the lower side of the material drop opening, and is used to support the packaging bag to allow the noodles in the material bin to enter the packaging bag;

[0023] The bag clamping and moving device comprises a base movably mounted on the frame and two clamping mechanisms, both of which are mounted on the base and are arranged opposite to each other, and are used to clamp the two ends of the bag opening of the packaging bag in the length direction after the noodles are filled in the packaging bag;

[0024] The bag clamping and moving device also includes an inference mechanism, which is installed on the base and includes an inference piece, and the inference piece can be relatively close to and away from the two clamping mechanisms in a direction perpendicular to the length direction of the bag opening of the packaging bag;

[0025] The inference piece is provided with an inference portion, which corresponds to the upper side or lower side of the portion of the packaging bag clamped by the clamping mechanism, so that the packaging bag can be pushed laterally when the inference piece is relatively close to the clamping mechanism.

[0026] The beneficial effect of the bulk noodle packaging machine provided by the present invention is that an inference mechanism is provided in the bag clamping and moving device of the bulk noodle packaging machine, and the inference piece in the inference mechanism can be relatively close to the two clamping mechanisms in a direction perpendicular to the length direction of the bag opening of the packaging bag. In this way, when the two clamping mechanisms clamp the packaging bag, the inference part on the inference piece can laterally push the upper side or the lower side of the part of the packaging bag clamped by the clamping mechanism, thereby inferring the noodles leaning against the bag opening of the packaging bag. The noodles leaning against the bag opening of the packaging bag will fall into the packaging bag after being inferred, thereby solving the problem of the noodles leaning against the bag opening of the packaging bag causing the sealing of the packaging bag to fail.

[0027] Furthermore, the inference mechanism also includes a linear action mechanism for driving the inference member to move, and the inference member is fixed on the movable end of the linear action mechanism. The inference member is only used to infer the noodles leaning against the bag mouth of the packaging bag. The structure is generally simple and the texture is light, which is convenient for controlling its movement. The clamping mechanism is heavy and has to drive the packaging bag containing the noodles, which is not easy to drive. Therefore, a linear action mechanism is set to drive the inference member to move so as to achieve the relative approach and distance between the inference member and the two clamping mechanisms. The requirements for the linear action mechanism are relatively low, which can reduce the cost of the bag clamping moving device, and thus reduce the cost of the bulk noodle packaging machine. In addition, compared with setting a linear action mechanism to drive the inference member to move, setting a linear action mechanism to drive the two relatively arranged clamping mechanisms to move can reduce the structural complexity of the bag clamping moving device, and thus reduce the structural complexity of the bulk noodle packaging machine.

[0028] Furthermore, the inference piece is an L-shaped plate whose length extends in the relative direction of the two clamping mechanisms, including a horizontal plate and a vertical plate perpendicular to each other, the vertical plate is fixedly connected to the movable end of the linear action mechanism, and the horizontal plate constitutes the inference part of the inference piece. The inference piece of this structural form has a simple structure and is easy to be fixedly connected to the movable end of the linear action mechanism.

[0029] Furthermore, the clamping mechanism has a clamping arm for clamping the packaging bag, and the horizontal plate corresponds to the lower side of the portion of the packaging bag clamped by the clamping arm. After the inference mechanism is installed on the base, the upper surface of the horizontal plate is close to the lower side of the clamping arm. When the clamping arm of the clamping mechanism clamps the packaging bag, the noodles leaning against the bag opening of the packaging bag are clamped by the portion of the packaging bag at the same height as the clamping arm. Because the noodles have a certain toughness, the closer the inference portion is to its clamped position, the easier it is to infer the noodles.

[0030] Alternatively, the clamping mechanism has a clamping arm for clamping the packaging bag, the horizontal plate corresponds to the upper side of the portion of the packaging bag clamped by the clamping arm, and after the inference mechanism is installed on the base, the lower surface of the horizontal plate is close to the upper side of the clamping arm. When the clamping arm of the clamping mechanism clamps the packaging bag, the noodles leaning against the bag opening of the packaging bag are clamped by the portion of the packaging bag at the same height as the clamping arm. Because the noodles have a certain toughness, the closer the inference portion is to its clamped position, the easier it is to infer the noodles.

[0031] Furthermore, the dimension of the inference part of the inference piece in the relative direction of the two clamping mechanisms is equal to the length dimension of the packaging bag. This arrangement facilitates the comprehensive inference of the noodles leaning against the inner side of the packaging bag. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0043] Embodiments of the bulk noodle packaging machine provided by the present invention:

[0044] like Figure 1 and Figure 2As shown, the bulk noodle packaging machine includes a frame 1, a bag loading device (not shown in the figure), a silo 2, a bag holding device 3, a bag clamping and moving device 4 and a conveyor belt 10; the frame 1 serves as the installation base of the bulk noodle packaging machine, and the bag loading device, the silo 2, the bag holding device 3, the bag clamping and moving device 4 and the conveyor belt 10 are all installed on the frame 1; a feeding port is provided at the lower part of the silo 2 for feeding noodles into the packaging bag, and the bag holding device 3 is arranged at the lower side of the feeding port; the bag loading device includes two supporting arms, which can open the bag opening of the packaging bag in the length direction, and drive the packaging bag to rotate after opening so that the bag opening is sleeved on the bag holding device 3; the bag holding device 3 includes two bag clamping mechanisms 11 arranged opposite to each other, and the bag clamping mechanism 1 .... The structure 11 includes a support plate 12 for supporting the packaging bag from the inside and a pressing plate 13 for pressing the packaging bag against the support plate 12 from the outside. The pressing plate 13 is installed on the movable end of the pressing plate cylinder 14 arranged in the bag clamping mechanism 11, and moves closer to and away from the support plate 12 under the control of the pressing plate cylinder 14; when the packaging bag is filled with noodles and is still clamped by the bag clamping mechanism 11 in the bag supporting device 3, the bag clamping moving device 4 clamps the packaging bag and transports the packaging bag to the sealing device (not shown in the figure) for heat sealing of the bag mouth of the packaging bag. After the packaging bag is sealed, the bag clamping moving device 4 releases the packaging bag, and the bagged noodles fall onto the conveyor belt 10 and are transported away (the conveyor belt 10 is arranged below the sealing device, and the sealing device is not shown in the figure).

[0045] like Figure 1 and Figure 3 As shown, the bulk noodle packaging machine also includes a support seat 5, which is fixedly mounted on the frame 1. A slide rail 6 extending along the conveying direction of the conveyor belt 10 is provided on the support seat 5. A slide seat 23 is arranged on the slide rail 6. The slide seat 23 can slide on the slide rail 6. The slide rail 6 is also provided with a slide seat driving mechanism for driving the slide seat 23 to move. The slide seat driving mechanism includes a conveyor belt 7, which is an annular conveyor belt. The conveyor belt 7 is wrapped around the outer side of the slide rail 6 along the length direction of the slide rail 6. The slide seat 23 is fixedly connected to the conveyor belt 7. The slide seat driving mechanism also includes a driving motor 8. The driving motor 8 drives the conveyor belt 7 to reciprocate. The slide seat 23 reciprocates on the slide rail 6 along with the conveyor belt 7 during the reciprocating motion of the conveyor belt 7; a side shift cylinder 9 is fixedly mounted on the slide seat 23, and the moving direction of the active end of the side shift cylinder 9 is perpendicular to the extension direction of the slide rail 6, and the active end of the side shift cylinder 9 moves in a horizontal plane.

[0046] The extension direction of the slide rail 6 is defined as the left-right direction. In this embodiment, when the packaging bag is tightened by the bag-stretching device 3, the length direction of the bag opening extends in the left-right direction, and the two support plates 12 for tightening the packaging bag are arranged in the front-back direction.

[0047] like Figure 3-Figure 6As shown, the bag clamping moving device 4 includes a base 15, on which a fixed frame 22 is fixed, and the fixed frame 22 is L-shaped. The fixed frame 22 includes a horizontal frame plate and a vertical frame plate, and the vertical frame plate extends upward from the front end of the horizontal frame plate. The horizontal frame plate is fixed on the base 15, and a clamping cylinder 16 is fixed on the front side of the vertical frame plate. The clamping cylinder 16 is a double-output end cylinder, and the two output ends of the clamping cylinder 16 are respectively located on the left and right sides of the clamping cylinder 16; a pneumatic clamping claw 18 is installed on the output end of the left side of the clamping cylinder 16, and an L-shaped folding plate 17 is fixed on the output end of the right side of the clamping cylinder 16, one plate of the folding plate 17 extends in the front-to-back direction, and the other plate extends in the left-to-right direction. The plate extending in the front-to-back direction is fixed on the output end of the clamping cylinder 16, and the plate extending in the left-to-right direction is fixed on the output end of the clamping cylinder 16. A sorting cylinder 19 is installed on the extended plate, and the output end of the sorting cylinder 19 faces to the right. A pneumatic clamp 18 is installed on the output end of the sorting cylinder 19. The pneumatic clamp 18 installed on the output end on the left side of the clamping cylinder 16 and the pneumatic clamp 18 installed on the output end of the sorting cylinder 19 are arranged opposite to each other, and the two are arranged at intervals in the left and right directions. The clamping arms of the two pneumatic clamps 18 are respectively used to clamp the two ends of the bag opening in the length direction of the packaging bag, and the clamping arms of the pneumatic clamps 18 clamp the packaging bag at the lower side of the seal on the packaging bag; because the two pneumatic clamps 18 are respectively connected to the two output ends of the clamping cylinder 16, the two pneumatic clamps 18 can move relative to and away from each other during the operation of the bag clamping moving device 4; the two pneumatic clamps 18 constitute the clamping mechanism in the bag clamping moving device 4.

[0048] like Figure 3-Figure 6As shown, a mounting frame 24 is fixedly installed on the fixing frame 22, and the mounting frame 24 includes a horizontal mounting plate and a vertical mounting plate. The vertical mounting plate is parallel to the vertical frame plate of the fixing frame 22 and is installed on the rear side of the vertical frame plate. The horizontal mounting plate of the mounting frame 24 extends forward and is above the clamping cylinder 16. An inference cylinder 20 is fixedly installed on the upper side of the horizontal mounting plate of the mounting frame 24. The movable end of the inference cylinder 20 is located on the front side of the inference cylinder 20. An L-shaped plate 21 with a length extending in the left and right direction is fixedly installed on the movable end of the inference cylinder 20. The length of the L-shaped plate 21 is equal to the length of the bag opening of the packaging bag. The L-shaped plate 21 includes a horizontal plate and a vertical plate, and the horizontal plate is located on the upper part of the vertical plate. The horizontal plate of the L-shaped plate 21 extends forward from the upper end of the vertical plate. The vertical plate of the L-shaped plate 21 is fixedly connected to the movable end of the inference cylinder 20. The L-shaped plate 21 can move in the front and rear directions under the drive of the inference cylinder 20. After the L-shaped plate 21 is installed on the movable end of the pushing cylinder 20, the upper surface of its horizontal plate is located on the lower side of the lower side of the clamping arms of the two pneumatic clamps 18; when the two pneumatic clamps 18 clamp the two ends of the bag opening in the length direction, the L-shaped plate 21 moves forward under the push of the pushing cylinder 20, so that the front end of the horizontal plate of the L-shaped plate 21 can push the bag, so that the noodles leaning against the bag opening of the bag can be pushed, and the pushed noodles will fall into the bag along the bag opening of the bag, thereby not affecting the subsequent sealing of the bag; the pushing cylinder 20 and the L-shaped plate 21 together constitute the pushing mechanism in the bag clamping and moving device 4, the pushing cylinder 20 constitutes the linear action mechanism in the pushing mechanism, the L-shaped plate 21 constitutes the pushing member in the pushing mechanism, and the horizontal plate of the L-shaped plate 21 constitutes the pushing part of the pushing member.

[0049] In order to ensure that the horizontal plate of the L-shaped plate 21 only needs to move forward a short distance after contacting the packaging bag to push out the noodles leaning against the bag opening of the packaging bag, there is only a small gap between the upper surface of the horizontal plate of the L-shaped plate 21 and the lower side surface of the clamping arm of the pneumatic clamp 18 in the up and down directions, and as long as it does not hinder the forward movement of the L-shaped plate 21, the gap between the upper surface of the horizontal plate of the L-shaped plate 21 and the lower side surface of the clamping arm of the pneumatic clamp 18 is as small as possible.

[0050] The bag clamping moving device 4 is installed on the side shifting cylinder 9. A guide rail extending in the front-to-back direction is provided on the upper surface of the fixed part of the side shifting cylinder 9. The base 15 of the bag clamping moving device 4 is L-shaped, including a horizontal seat body and a vertical seat body. The vertical seat body of the base 15 extends downward from the front end of the horizontal seat body. The lower part of the horizontal seat body of the base 15 is provided with a guide groove adapted to the guide rail on the side shifting cylinder 9. The base 15 is guided and assembled on the side shifting cylinder 9. The vertical seat body of the base 15 is fixedly connected to the movable end of the side shifting cylinder 9 so as to move under the drive of the side shifting cylinder 9.

[0051] When the bulk noodle packaging machine is in use, first, the bag loading device brings the packaging bag to the bag holding device 3, the bag holding device 3 holds the bag opening of the packaging bag open, and then the noodles in the silo 2 enter the packaging bag through the drop opening; at the same time, the driving motor 8 and the side shifting cylinder 9 are activated, and the bag clamping mobile device 4 is sent to the bottom of the bag holding device 3. In the process of the bag clamping mobile device 4 being sent to the bottom of the bag holding device 3, the clamping cylinder 16 drives the two pneumatic clamps 18 to move away from each other so that there is a large distance between the two. When the bag clamping mobile device 4 moves into place, the clamping cylinder 16 controls the relative movement of the two pneumatic clamps 18, and then the two pneumatic clamps 18 clamp the two ends of the bag opening in the length direction of the packaging bag. At the same time, the inference cylinder 20 drives the L-shaped plate 21 to move forward. Before the front end of the horizontal plate of the L-shaped plate 21 contacts the packaging bag, the two pneumatic clamps 18 has clamped the packaging bag, and while the L-shaped plate 21 continues to move forward, the noodles leaning against the bag opening of the packaging bag can be pushed out; then the side-moving cylinder 9 drives the bag clamping mobile device 4 to move backward, and the packaging bag is separated from the bag supporting device 3. At the same time, the driving motor 8 drives the conveyor belt 7 to move and drive the bag clamping mobile device 4 to move left, so that the bag clamping mobile device 4 moves to the sealing device position to seal the packaging bag. When the two pneumatic clamps 18 clamp the packaging bag, the active end of the arranging cylinder 19 extends out to control the corresponding pneumatic clamp 18 to move away from the other pneumatic clamp 18, thereby arranging the bag opening of the packaging bag to be relatively flat to prevent wrinkles from occurring when the packaging bag is subsequently sealed. After the bag opening of the packaging bag is sealed, the two pneumatic clamps 18 release the packaging bag, and the packaging bag falls onto the conveyor belt 10 and is transported away by the conveyor belt 10.

[0052] In this embodiment, the two pneumatic clamps 18 and the inference cylinder 20 are controlled by a solenoid valve (not shown in the figure), so as to achieve coordinated action of the three.

[0053] In the above embodiment, the upper surface of the horizontal plate of the L-shaped plate is located below the lower side of the clamping arms of the two pneumatic clamps, and there is only a small gap between the upper surface of the horizontal plate and the lower side of the clamping arms of the two pneumatic clamps in the vertical direction. In other embodiments, the upper surface of the horizontal plate and the lower side of the clamping arms of the two pneumatic clamps may also have a larger spacing in the vertical direction. In this case, if the hanging noodles are to be pushed, the L-shaped plate needs to move forward a larger distance; in other embodiments, it can also be set that: after the L-shaped plate is installed on the pushing cylinder, the lower surface of its horizontal plate is on the upper side of the upper side of the clamping arms of the two pneumatic clamps. In this case, it can also be further set that there is only a small gap between the lower side of the horizontal plate and the upper side of the clamping arms of the two pneumatic clamps in the vertical direction.

[0054] In the above embodiment, the L-shaped plate is pushed by the pushing cylinder to achieve relative approach and distance with the pneumatic clamping claw. In other embodiments, the L-shaped plate can also be directly fixed on the mounting frame, and a movable cylinder is set on each of the two movable ends of the clamping cylinder, the movable ends of the two movable cylinders face forward, and the two movable cylinders act synchronously, and the pneumatic clamping claw on the left is fixed on the movable end of the movable cylinder on the left, and the folding plate is fixed on the movable end of the movable cylinder on the right. In this way, the two movable cylinders can drive the two pneumatic clamping claws to move forward and backward, thereby achieving relative approach and distance between the L-shaped plate and the two pneumatic clamping claws, and also achieving the L-shaped plate pushing the noodles in the packaging bag against the bag mouth of the packaging bag.

[0055] In the above embodiment, the linear motion mechanism is a cylinder. In other embodiments, the linear motion mechanism may also be in other structural forms, such as a motor for a screw nut mechanism, or a gear rack mechanism for a motor. Both can be used.

[0056] In the above embodiment, the length of the L-shaped plate is equal to the length of the bag opening of the packaging bag. In other embodiments, the length of the L-shaped plate can also be less than or greater than the length of the bag opening of the packaging bag, and can also be used.

[0057] In the above-mentioned embodiment, the inference member is composed of an L-shaped plate. In other embodiments, the inference member may also be a structure of other forms, such as being only a horizontal plate, which is fixed on the horizontal mounting plate of the mounting frame and can be used equally.

[0058] The present invention further provides a bag clamping and moving device, the structure of which is the same as that of the bag clamping and moving device in the embodiment of the above-mentioned bulk noodle packaging machine, and will not be described in detail here.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. The patent protection scope of the present invention shall be based on the claims. All equivalent structural changes made using the contents of the description and drawings of the present invention should also be included in the protection scope of the present invention.
