Description

Technical Field

[0001] The present invention relates to the field of packaging machines, and particularly to portable packaging machines.

Background Art

[0002] Portal packaging machines are packaging facilities that are convenient to carry, and are used for the purpose of carrying the equipment to the relevant workplace and packaging goods.

[0003] Patent number CN212333061U discloses a portable packaging machine that can prevent misoperation. This packaging machine includes control structures such as a tightening wheel button 3, a belt rubbing button 10, and a handle 13, and includes a relatively large number of control structures. Therefore, it not only increases the control difficulty during user operation, but also when the user holds the packaging machine, they have to pay attention to different control structures. For this reason, the risk of misoperation becomes high. Not only that, but the existing portable packaging machines in the prior art require force for operation because a large handle is used to apply force to open the lever. The above lever is an important member for applying tension to the packaging belt.

[0004] In a portal packaging machine, the welding mechanism connects the head and tail ends of the packaging belt together by heating. After the welding mechanism connects the packaging belt, the welded upper tooth plate can be lifted so that the connected packaging belt can be taken out. In the existing welding mechanism, a long handle is provided separately or an electronic button is provided to control the lifting of the upper tooth plate, increasing the operation process.

[Modes for carrying out the invention]

[0032] Example 1 (See Figures 1 to 10)

[0033] This invention provides a portal packaging machine that enables the raising and lowering of the welded tooth plate through a single control module and motor, and allows control of the distance between the tension wheel and the tension tooth plate. This not only simplifies control but also reduces the labor required for operation and solves problems present in existing technologies.

[0034] The technical means of the embodiments of the present invention will be described clearly and in detail below with reference to the drawings in the embodiments. The embodiments described are only a part of the present invention, not all embodiments. All other embodiments obtained by an ordinary person of the art without creative work based on the embodiments of the present invention are all within the scope of the protection of the present invention. As shown in Figures 1 to 10, the portal packaging machine of the present invention includes a motor 1, a welding module 2, and a tension module 3, and further includes a control module 4, a first transmission unit 5, and a second transmission unit 6.

[0035] The motor 1 is operated by the control signal of the control module 4. The motor 1 controls the raising and lowering of the welded tooth plate 21 of the welding module 2 through the first transmission unit 5. The motor 1 controls the distance between the tension wheel 31 and the tension tooth plate 32 in the tension module 3 via the second transmission unit 6.

[0036] In this embodiment of the present invention, a single motor 1 can control the raising and lowering of the welded tooth plate 21 and the spacing between the tension wheel 31 and the tension tooth plate 32 via the first transmission unit 5 and the second transmission unit 6.

[0037] Specifically, motor 1 begins operation upon receiving a control signal from control module 4. Furthermore, motor 1 controls the raising and lowering of the welded tooth plate 21 of welding module 2 via first transmission unit 5, and controls the distance between the tension wheel 31 and tension tooth plate 32 in tension module 3 via second transmission unit 6. It should be noted that both the first transmission unit 5 and the second transmission unit 6 are connected to motor 1, and specifically, can, but are not limited to, the drive wheels on the rotation axis of motor 1. The control module 4 may specifically be a handle, electronic button, or touch switch.

[0038] The main point to explain here is that, in this invention, motor 1 controls the raising and lowering of the welded tooth plate 21 of the welding module 2, but it does not necessarily need to be involved in the entire process of raising or lowering the welded tooth plate 21; the raising and lowering process is completed together with other motors. The specific raising and lowering process will be described in detail below.

[0039] It should be explained that the motor 1 of the present invention can be a servo motor, a servo mechanism, etc., and in this embodiment, a servo mechanism is preferred, but it is not limited thereto.

[0040] Preferably, the control module 4 includes an operating handle 41 with resetting control and a control switch 42. The control switch 42 is activated by pulling the operating handle 41.

[0041] In the present invention, the control module 4 preferably combines an operating handle 41 with resetting control and a control switch 42. Of these, the operating handle 41 has the advantage of being easy to operate and can greatly improve the user's operating feel.

[0042] Preferably, the portal packaging machine comprises a work area 001, a handle operation area 002, and a power supply area 003 arranged in that order. The operating handle 41 is located in the handle operation area 002, or it is located in the work area 001 and extends to the position of the handle operation area 002.

[0043] Preferably, the operating handle 41 is located below the handle 0021 in the handle operating area 002, and is positioned so that it can be operated with the index finger or middle finger when gripping the handle 0021 with the hand.

[0044] It should be explained that if the control module 4 includes an operating handle 41, the operating handle 41 can be a relatively small and short handle. Such a small handle, after being placed below the handle 0021, can be operated with the user's index or middle finger when holding and working with the portal packaging machine, making it very convenient and providing an excellent operating feel. This is a significant difference from the large handles of existing portal packaging machines, which required either lowering the machine or pulling it with force using another hand.

[0045] Preferably, the operating handle 41 comprises a pull portion 411, a rotating portion 412, and a control portion 413. Of these, the control portion 413 is used to activate the control switch 42. The rotating portion 412 and the control portion 413 are provided within the work area 001 through a position-relief groove 0011 opened in the work area 001, the pull portion 411 extends from the position-relief groove 0011 to below the handle 0021, a torsion spring 414 for controlling the return of the operating handle 41 is provided on the rotating portion 412, and the control switch 42 is an induction switch.

[0046] What needs to be explained is that when the pull part 411 is pulled with the index finger or middle finger (generally the index finger) and the operating handle 41 rotates, the control unit 413 releases the control switch 42, which then issues a control signal, causing the motor 1 to operate according to the control signal.

[0047] Preferably, a third transmission unit 7 is provided between the motor 1 and the second transmission unit 6. The motor 1 controls the locking and unlocking of the output wheel of the tension motor 33 in the tension module 3 via the third transmission unit 7. The output wheel is connected to the tension wheel 31 via a planetary reduction mechanism.

[0048] First, it should be explained that in the embodiments of the present invention, locking the output wheel does not necessarily restrict the output wheel from rotating, but rather restricts it to rotating in only one direction. Therefore, when the output wheel is released, it can rotate both forward and backward. In addition, the third transmission unit 7 of the present invention is suitable for portal balers using a planetary reduction mechanism and is not suitable for structures using a worm gear transmission. In a portal baler using a planetary reduction mechanism design, a single motor 1 of the present invention can achieve triple control of the raising and lowering of the welded tooth plate 21, the locking and unlocking of the tension motor 33 output wheel, and the spacing between the tension wheel 31 and the tension tooth plate 32. In summary, triple control can be achieved more directly by operating the operating handle 41 with the user's index or middle finger through the control module 4. Such a method has the advantages of labor-saving operation, ease of use, and superior operating feel, and can better satisfy the needs of actual operators.

[0049] It should be noted that the above triple control can use a synchronous method or a sequential method. When using the sequential method, the following procedure is generally used. That is, when the pull part 411 is pulled, first the cam rotates to lift the welded tooth plate 21, then the output wheel of the tension motor 33 is released, enabling forward and reverse rotation of the output wheel, that is, the tension wheel 31 can rotate freely at this time, and finally, the gap between the tension wheel 31 and the tension tooth plate 32 is increased, and when the tension wheel 31 moves away from the tension tooth plate 32, the welded packaging belt can be removed.

[0050] Preferably, the first transmission unit 5 comprises a first transmission member 51 and a cam 52 driven by a motor 1. The first transmission member 51 rotates synchronously with the cam 52. The welding module 2 includes a toggle lever component. The toggle lever component includes a rotatable toggle lever 22 and a connecting member 23. One end of the toggle lever 22 is provided with a projection block 221 that engages with the cam 52 and connects to the weld tooth plate 21 through the connecting member 23. The other end of the toggle lever 22 is driven by the welding motor 24 when it has rotated to connect with the welding motor 24 of the welding module 2.

[0051] In this embodiment of the present invention, the cam 52 is rotated during the rotation of the first transmission member 51. As the cam 52 rotates, it presses the toggle lever 22 downwards. That is, the toggle lever 22 rotates, and as it rotates, one end of the toggle lever 22 slowly approaches the welding motor 24 and makes contact with it. The welding motor 24 further drives the toggle lever 22, causing it to rotate further, and at the same time, the toggle lever 22 lifts the welded tooth plate 21 through the connecting member 23. Overall, the first transmission member 51 mainly plays the role of connecting the toggle lever 22 and the welding motor 24. The welding motor 24 plays the role of outputting power to lift the welded tooth plate 21.

[0052] Here, the process by which the motor 1 controls the raising and lowering of the welded upper tooth plate 21 of the welding joule 2 via the first transmission unit 5 will be explained in detail. When it is desired to raise the welded upper tooth plate 21, the motor 1's role is to rotate the toggle lever 22 to a position where it engages with the welding motor 24, driven by the cam 52, and to continue rotating the toggle lever 22 until the welded upper tooth plate 21 rises to an appropriate position by the welding motor 24. When the operating handle 41 is loosened and the control switch 42 is struck again, that is, when the motor 1 receives a control signal again, the motor 1 controls the rotation of the cam 52 and yields its position to the toggle lever 22 so as not to interfere when the welded upper tooth plate 21 is lowered. The welded upper tooth plate 21 can be lowered by various means, such as by gravity or by the driving of the welding motor 24. In other words, the motor 1 of the present invention can control only the initial processes of raising and lowering the welded tooth plate 21, rather than controlling the entire process, by controlling the raising and lowering of the welded tooth plate 21 of the welding module 2 through the first transmission unit 5. No limitations are made here.

[0053] Preferably, the second transmission unit 6 includes a second transmission member 61 and claws 62 provided at both ends of the second transmission member 61 and a tension tooth plate drive block 63, wherein the tension tooth plate drive block 63 rotates synchronously with the second transmission member 61, the claws 62 are movably mounted on the second transmission member 61, and the tension tooth plate drive block 63 drives the tension tooth plate 32 directly or indirectly through a transient member 64.

[0054] In this embodiment of the present invention, the motor 1 synchronously rotates the tension tooth plate drive block 63 in the process of driving the second transmission member 61, and directly or indirectly through the transient member 64 drives and rotates the tension tooth plate 32 in the process of the rotation of the tension tooth plate drive block 63. It should be noted that the transient member 64 can be a mechanical member having a transmission function such as a ring gear or a gear, but is not limited to this. In addition, in the process of the rotation of the second transmission member 61, the pawl 62 does not move along with it, but is driven and rotated by the third transmission unit 7, which will be explained in detail below.

[0055] Preferably, the third transmission unit 7 comprises a third transmission member 71 and a pressing block 72 that rotates synchronously with the third transmission member 71. The motor 1 drives the third transmission member 71 and drives the second transmission member 61 through the third transmission member 71. The tension module 3 further comprises a ratchet wheel 34 that rotates synchronously with the output wheel. The ratchet wheel 34 engages with a pawl 62, and one end of the pawl 62 is fitted with a rotating arm 621 that engages with the pressing block 72, and the other end is fitted with a ratchet arm 622 that engages with the pawl 34, of which one end of the ratchet arm 622 is fitted with a projection 6221 that engages with the ratchet wheel 34, and the other end is fitted with a spring 6222, and the pressing block 72 drives the pawl 62 during rotation until the ratchet arm 622 disengages from the ratchet wheel 34.

[0056] To explain, motor 1 drives the second transmission member 61 through the third transmission member 71, and the third transmission member 71 drives the rotating pressure block 72 to rotate synchronously. When the pressure block 72 rotates, it applies a downward force to the rotating arm 621, causing the claw 62 to rotate due to the downward force, which moves the claw arm 622 to rotate. While the claw arm 622 is rotating, the spring is compressed and it slowly moves out of the range of the claw wheel 34, and the entire process is completed when it completely moves out of the claw wheel 34. At this time, the claw wheel 34 can rotate freely, and the output wheel and the claw wheel 34 rotate synchronously. Therefore, at this time the output wheel can also rotate freely and releases the output wheel of the tension motor 33. In addition, when motor 1 stops outputting power, the claw 62 rotates in the opposite direction due to the action of the spring 6222, locking the output wheel of the tension motor 33 again, and it can only rotate in one direction.

[0057] Preferably, the first transmission member 51, the second transmission member 61, and the third transmission member 71 are all gears. The motor 1 is provided with a drive gear 11. The first transmission member 51, the drive gear 11, the third transmission member 71, and the second transmission member 61 are arranged to contact each other in sequence. The welding motor 24 is provided with a welding drive wheel 25. The toggle lever 22 is provided with toggle teeth 222 that engage with the welding drive wheel 25.

[0058] It should be explained that the first transmission member 51, the second transmission member 61, and the third transmission member 71 can all be gears. Furthermore, the first transmission member 51, the drive gear 11, the third transmission member 71, and the second transmission member 61 are arranged to contact each other in sequence. In other words, the drive gear 11 can simultaneously drive the rotation of the first transmission member 51, the second transmission member 61, and the third transmission member 71. In addition, when the toggle teeth 222 and the teeth of the welded drive wheel 25 mesh, the welded drive wheel 25 drives the rotation of the toggle lever 22.

[0059] The portal baler provided by the present invention comprises a motor 1, a welding module 2, and a tension module 3, and further comprises a control module 4, a first transmission unit 5, and a second transmission module 6. Motor 1 is operated by a control signal from the control module 4. Motor 1 controls the raising and lowering of the welded tooth plate 21 of the welding module 2 through the first transmission unit 5. Motor 1 controls the distance between the tension wheel 31 and the tension tooth plate 32 in the tension module 3 through the second transmission unit 6. Thus, the raising and lowering of the welded tooth plate 21 can be achieved with a single control module 4 and motor 1, and by controlling the distance between the tension wheel 31 and the tension tooth plate 32, the portal baler of the present invention not only becomes easier to control but is also expected to reduce the labor required for operation and solve problems that exist in existing technologies.

[0060] Example 2 (See Figures 11-18)

[0061] This invention discloses a welding mechanism that uses a control motor and a welding motor design to achieve lifting of the welded tooth plate by driving a toggle lever, allowing the control motor to raise the welded tooth plate without additional operation, thus solving the shortcomings of existing technologies.

[0062] The technical means in the embodiments of the present invention will be described clearly and in detail below with reference to the drawings in the embodiments. The embodiments described are only some, and not all, embodiments of the present invention. All other embodiments obtained by an ordinary person of the art without creative work based on the embodiments of the present invention are all within the scope of the present invention. Figure 1 shows a welding mechanism of the present invention used in a portal packaging machine and connected to a control motor 1b in the portal packaging machine, and including a toggle lever component and a welding motor component.

[0063] The toggle lever component includes a rotatable toggle lever 2b and a connecting member 3b, of which one end of the toggle lever 2b is driven by a control motor 1b and connects to the welded tooth plate 4b through the connecting member 3b. The other end of the toggle lever 2b rotates to a state where it is connected to a welding motor 5b of the welding motor component, and is then driven by the welding motor 5b.

[0064] In this invention, the control motor 1b plays a guide control role. When it is necessary to raise the welded tooth plate 4b, the control motor 1b drives the rotation of the toggle lever 2b. As the toggle lever 2b rotates, it is linked to the raising of the welded tooth plate 4b through the connecting member 3b, and when one end of the toggle lever 2b is connected to the welding motor 5b of the welding motor component, the welding motor 5b provides power to continue rotating the toggle lever 2b. In other words, it continues to raise the welded tooth plate 4b to the set position. When the control motor 1b has completed raising the welded tooth plate 4b, the control motor 1b cuts off the output power between the toggle levers 2b, and the control motor 1b reverses to control the lowering of the welded tooth plate 4b, but this is not limited to this.

[0065] It should be explained that the control motor 1b of the present invention can be a servo motor, a servo mechanism, etc., and although a servo mechanism is used in this embodiment, it is not limited thereto.

[0066] Preferably, the welding motor component comprises a welding motor 5b and a welding drive wheel 6b provided on the welding motor 5b. The toggle lever 2b is provided with toggle teeth 21b that engage with the welding drive wheel 6b.

[0067] What needs to be explained is that when the toggle lever 2b rotates to the position where the toggle teeth 21b and the welding drive wheel 6b engage, the welding motor 5b continues to provide rotational power, but at this point, the control motor 1b no longer drives the toggle lever 2b.

[0068] Preferably, the toggle lever 2b has an L-shaped structure. The lateral portion of the L-shaped structure is connected to the welded tooth plate 4b via a connecting member 3b, and the longitudinal portion is provided with toggle teeth 21b. When the toggle lever 2b rotates until it connects to the welded drive wheel 6b, the welded tooth plate 4b, the connecting member 3b, the lateral portion of the toggle lever 2b, the longitudinal portion of the toggle lever 2b, and the welded drive wheel 6b are connected in that order.

[0069] In this invention, the welded upper tooth plate 4b, the connecting member 3b, the lateral portion of the toggle lever 2b, the longitudinal portion of the toggle lever 2b, and the welding drive wheel 6b are connected in sequence. Therefore, when the toggle lever 2b is driven by the control motor 1b to rotate, the lateral portion of the toggle lever 2b pulls the welded upper tooth plate 4b upward. The longitudinal portion of the toggle lever 2b gradually approaches the welding drive wheel 6b. Once it engages with the welding drive wheel 6b, the welding motor 5b continues to provide rotational power.

[0070] Preferably, movable sheets are provided at both ends of the connecting member 3b, and the two movable sheets are connected to the lateral portion and the welded tooth plate 4b, respectively.

[0071] Preferably, the control motor 1b drives the toggle lever 2b through a first transmission unit 7b. The first transmission unit 7b includes a first transmission member 71b and a cam 72b, which are driven by the control motor 1b. The first transmission member 71b rotates synchronously with the cam 72b, and one end of the toggle lever 2b is provided with a projection block 22b that engages with the cam 72b, while the other end of the toggle lever 2b is connected to a welding motor 5b.

[0072] In this invention, the control motor 1b can control the toggle lever 2b through the first transmission unit 7b. Specifically, the control motor 1b drives the rotation of the first transmission member 71b. The first transmission member 71b rotates synchronously with the cam 72b. As a result, the cam 72 also rotates simultaneously and comes into contact with the projection block 22b. The projection block 22b receives a force and undergoes a positional shift, which in turn drives the toggle lever 2b to rotate.

[0073] Preferably, the control motor 1b is provided with a drive gear 11b. The first transmission member 71b is a gear that engages with the drive gear 11b. The first transmission member 71b is provided coaxially with the cam 72b.

[0074] Preferably, the control motor 1b is operated by a control signal coming from a control module 8b located inside the portal packaging machine.

[0075] It should be explained that the drive gear 11b may not only engage with the first transmission member 71b, but may also include other transmission members that engage with it simultaneously. If there are multiple transmission members that engage with the drive gear 11b simultaneously, the control motor 1b can perform multiple functions at the same time. In other words, upon receiving control signals from the control module 8b, multiple operating processes can be performed simultaneously or sequentially, but this is not limited here.

[0076] Preferably, the control module 8b includes an operating handle 81b with resetting control and a control switch 82b. Of these, pulling the operating handle 81b activates the control switch 82b.

[0077] In the present invention, the control module 8b preferably employs a combination of an operating handle 81b with resetting control and a control switch 82b. Of these, the operating handle 81b has the advantage of being easy to operate and can greatly improve the user's operating feel.

[0078] Preferably, the portal packaging machine consists of a work area 001b, a handle operation area 002b, and a power supply area 003b arranged in that order, and the operating handle 81b is provided in the handle operation area 002b or in the work area 001b and extends to the position of the handle operation area 002b and is positioned so that it can be operated with the index finger or middle finger when gripping the handle 0021b with the hand.

[0079] It should be explained that if the control module 8b includes an operating handle 81b, the operating handle 81b can be a relatively small and short handle. Placing such a small handle below the grip 0021b makes it very convenient for the user to operate with their index or middle finger when working with the packaging machine, and a superior operating feel can be expected. This is a significant difference from the large handles on existing portal packaging machines, which had to be lowered or pulled with force using another hand.

[0080] Preferably, the operating handle 81b comprises a pull portion 811b, a rotating portion 812b, and a control portion 813b. Of these, the control portion 813b is used to activate the control switch 82b. The rotating portion 812b and the control portion 813b are located within the work area 001b through a position-relief groove 0011b provided in the work area 001b. The pull portion 811b extends from the position-relief groove 0011b to below the handle 0021b, a torsion spring 83b for controlling the return of the operating handle 81b is installed on the rotating portion 812b, and the control switch 82b is an induction switch.

[0081] What needs to be explained is that the index finger or middle finger generally refers to the case where the index finger is used to pull the pull part 811b, and when the operating handle 81b rotates and the control unit 813b releases the control switch 82b, the control switch 82b outputs a control signal, and the motor 1b operates according to the control signal.

[0082] The welding mechanism provided by the present invention is used in a portal packaging machine and is connected to a control motor 1b in the portal packaging machine. This welding mechanism includes a toggle lever component and a welding motor component. The toggle lever component includes a rotatable toggle lever 2b and a connecting member 3b. One end of the toggle lever 2b is driven by the control motor 1b, and the connecting member 3b is driven by the welding motor when it rotates until it connects to the welding tooth plate 4b and the other end connects to the welding motor 5b of the welding motor component. By using the design of the control motor 1b and welding motor 5b, the lifting of the welding tooth plate 4b can be achieved through the way the toggle lever 2b is driven, and the welding mechanism of the present invention can drive the lifting of the welding tooth plate by the control motor 1b without extra operation, thus solving the shortcomings present in existing technologies.

[0083] The above is a detailed description of the portal packaging machine provided by the present invention. However, an ordinary technician in the art can see that many variations can be made in terms of specific embodiments and scope of application, depending on the embodiments of the present invention. In summary, the contents of this specification should not be understood as limitations on the present invention.
