Description

A portable baler Technical Field

[0001] The present invention relates to the field of baling machines, in particular to a portable baling machine. Background Art

[0002] A portable baler is a kind of portable baling equipment, which is used to carry it to the relevant work site to bundle items.

[0003] Patent number CN212333061U discloses a portable baler designed to prevent misoperation. This baler includes control structures such as a tightening wheel button 3, a belt-rubbing button 10, and a handle 13. The numerous control structures not only increase the user's difficulty in using the baler, but also require the user to distract themselves from operating the various control structures while holding the baler, increasing the risk of misoperation. Furthermore, conventional portable balers require a large handle to forcefully open a rocker, which is a key component for tightening the strap. This operation is laborious.

[0004] In portable strapping machines, the welding mechanism connects the ends of the strapping tape by heating. After the welding mechanism connects the strapping tape, the upper welding tooth plate needs to be raised to remove the connected strapping tape. Existing welding mechanisms use an additional long handle or electronic button to control the lifting of the upper welding tooth plate, which increases the operating process.

[0053] Example 1, refer to Figures 1 to 10.

[0054] The present invention discloses a portable baler, which can realize the lifting and lowering of the welding upper tooth plate and control the spacing between the tensioning wheel and the tensioning tooth plate through a control module and an electric motor. It is not only simple and convenient to control, but also more labor-saving to operate, and can solve the problems existing in the prior art.

[0055] The following is a clear and detailed description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Please refer to Figures 1 to 10, which are the portable baler of the present invention, including a motor 1, a welding module 2 and a tensioning module 3, including: a control module 4, a first transmission unit 5 and a second transmission unit 6;

[0056] The motor 1 operates according to the control signal of the control module 4;

[0057] The motor 1 controls the lifting and lowering of the welding upper tooth plate 21 of the welding module 2 through the first transmission unit 5;

[0058] The motor 1 controls the distance between the tensioning wheel 31 and the tensioning tooth plate 32 in the tensioning module 3 through the second transmission unit 6 .

[0059] In an embodiment of the present invention, a motor 1 can realize the lifting and lowering of the welding upper tooth plate 21 and the control of the spacing between the tensioning wheel 31 and the tensioning tooth plate 32 through the first transmission unit 5 and the second transmission unit 6. Specifically, after the motor 1 receives the control signal from the control module 4, it will start working and control the lifting and lowering of the welding upper tooth plate 21 of the welding module 2 through the first transmission unit 5, and control the spacing between the tensioning wheel 31 and the tensioning tooth plate 32 in the tensioning module 3 through the second transmission unit 6. It should be noted that the first transmission unit 5 and the second transmission unit 6 are both connected to the motor 1, and specifically can be connected to the drive wheel on the rotating shaft of the motor 1, which is not limited here. The above-mentioned control module 4 can specifically be a handle, an electronic button or a touch switch, etc.

[0060] Here, it must be pointed out that the motor 1 in the present invention controls the lifting and lowering of the welding upper tooth plate 21 of the welding module 2, and does not have to participate in the entire rising or falling process of the welding upper tooth plate 21, but can cooperate with other motors to complete the lifting process. The specific lifting process will be described in detail later.

[0061] It should be noted that the electric motor 1 of the present invention may be a servo motor, a steering gear, etc. In this embodiment, a steering gear is preferred, which is not limited here.

[0062] Preferably, the control module 4 includes an operating handle 41 with a reset design and a control switch 42 , wherein the control switch 42 is triggered by pulling the operating handle 41 .

[0063] In the present invention, the control module 4 is preferably a combination of an operating handle 41 with a reset design and a control switch 42, wherein the operating handle 41 has the advantage of being easy to operate and can greatly improve the user's operating feel.

[0064] Preferably, the portable baler is composed of a working area 001, a handle operating area 002 and a power supply area 003 connected in sequence; the operating handle 41 is arranged in the handle operating area 002, or is arranged in the working area 001 and extends to the handle operating area 002.

[0065] Preferably, the operating handle 41 is arranged below the handle 0021 of the handle operating area 002, and is arranged at a position suitable for operation by the index finger and / or middle finger when the handle 0021 is held.

[0066] It should be noted that when the control module 4 includes an operating handle 41, the operating handle 41 can be a smaller and shorter handle. After this small handle is set under the handle 0021, it is very convenient for the user to operate with the index finger or / and middle finger when lifting the portable baler to work, and a good operating feel can be obtained, which is completely different from the existing large handle that requires the portable baler to be put down or the other hand to be used to vigorously pull it.

[0067] Preferably, the operating handle 41 includes a pulling part 411, a rotating part 412 and a control part 413, wherein the control part 413 is used to trigger the control switch 42; the rotating part 412 and the control part 413 are arranged in the working area 001 through the give way slot 0011 opened on the working area 001, and the pulling part 411 extends from the give way slot 0011 to the bottom of the handle 0021; the rotating part 412 is provided with a torsion spring 414 for controlling the reset of the operating handle 41; the control switch 42 is an induction switch.

[0068] It should be noted that when the index finger or / and middle finger, generally the index finger, pulls the trigger part 411, the operating handle 41 rotates, and after the control part 413 leaves the control switch 42, the control switch 42 sends a control signal, and the motor 1 will work according to the control signal.

[0069] Preferably, a third transmission unit 7 is further provided between the motor 1 and the second transmission unit 6; the motor 1 controls the locking and releasing of the output wheel of the tensioning motor 33 in the tensioning module 3 through the third transmission unit 7, wherein the output wheel is connected to the tensioning wheel 31 through a planetary reduction structure.

[0070] First, it should be noted that, in the embodiment of the present invention, locking the output wheel does not restrict the output wheel from rotating, but rather restricts the output wheel to only one-way rotation. Therefore, after releasing the output wheel, the output wheel can achieve forward and reverse rotation. In addition, the third transmission unit 7 of the present invention is suitable for portable balers designed with a planetary reduction structure, rather than a structure using a worm gear transmission. In portable balers designed with a planetary reduction structure, the present invention can achieve triple control by a single motor 1: raising and lowering the welding upper tooth plate 21, locking and releasing the output wheel of the tensioning motor 33, and controlling the spacing between the tensioning wheel 31 and the tensioning tooth plate 32. In short, through the control module 4, triple control can be achieved more directly by operating the operating handle 41 with the index finger or / and middle finger of the user. This operation method has the advantages of labor-saving operation, ease of use, and a strong sense of operation, and is more in line with the needs of actual operators.

[0071] It must be pointed out that the above-mentioned triple control can be carried out synchronously or sequentially. When the sequential control is adopted, the following sequence is generally adopted: that is, after the pull part 411 is pulled, the cam is first rotated to lift the welded upper tooth plate 21; then the output wheel of the tensioning motor 33 is released, and the output wheel can realize forward and reverse rotation, that is, the tensioning wheel 31 can rotate freely at this time; finally, the distance between the tensioning wheel 31 and the tensioning tooth plate 32 is increased. After the tensioning wheel 31 is disengaged from the tensioning tooth plate 32, the welded strapping tape can be removed.

[0072] Preferably, the first transmission unit 5 includes a first transmission component 51 and a cam 52 driven by the motor 1, and the first transmission component 51 rotates synchronously with the cam 52; the welding module 2 includes a toggle rod assembly, and the toggle rod assembly includes a rotatable toggle rod 22 and a connecting member 23; one end of the toggle rod 22 is provided with a protrusion 221 that cooperates with the cam 52, and is connected to the welding upper tooth plate 21 through the connecting member 23, and the other end is rotated to be connected to the welding motor 24 of the welding module 2 and then driven by the welding motor 24.

[0073] In this embodiment of the present invention, the rotation of the first transmission component 51 drives the cam 52 to rotate. During the rotation of the cam 52, the toggle lever 22 is pressed downward, that is, the toggle lever 22 rotates. During the rotation of the toggle lever 22, one end of the toggle lever 22 gradually approaches the welding motor 24 until it contacts the welding motor 24. The welding motor 24 drives the toggle lever 22 to rotate further. At the same time, the toggle lever 22 pulls the upper welding tooth plate 21 upward through the connecting member 23. In general, the first transmission component 51 mainly serves to connect the toggle lever 22 to the welding motor 24, and the welding motor 24 serves to output the power to lift the upper welding tooth plate 21.

[0074] Here, the process of the motor 1 controlling the raising and lowering of the welding upper tooth plate 21 of the welding module 2 through the first transmission unit 5 is described in detail: when the welding upper tooth plate 21 needs to be raised, the motor 1 drives the toggle rod 22 to rotate through the cam 52 until it cooperates with the welding motor 24, and the welding motor 24 drives the toggle rod 22 to continue rotating until the welding upper tooth plate 21 rises to the appropriate position; when the operating handle 41 is released and pressed against the control switch 42 again, that is, when the motor 1 receives the control signal again, the motor 1 controls the cam 52 to rotate and make way for the toggle rod 22 so that the welding upper tooth plate 21 is not hindered when it descends, wherein the descent of the welding upper tooth plate 21 can be achieved by various methods such as its own gravity or by being driven to descend by the welding motor 24. That is, the motor 1 of the present invention controls the raising and lowering of the welding upper tooth plate 21 of the welding module 2 through the first transmission unit 5, which can only control the initial process of the raising and lowering of the welding upper tooth plate 21, rather than the entire process, and is not limited here.

[0075] Preferably, the second transmission unit 6 includes a second transmission component 61, and a pawl 62 and a tensioning tooth plate driving block 63 arranged at both ends of the second transmission component 61, wherein the tensioning tooth plate driving block 63 rotates synchronously with the second transmission component 61, and the pawl 62 is movably mounted on the second transmission component 61; the tensioning tooth plate driving block 63 drives the tensioning tooth plate 32 directly or indirectly through a transition piece 64.

[0076] In this embodiment of the present invention, the motor 1 drives the second transmission component 61, thereby driving the tensioning rack drive block 63 to rotate synchronously. This rotation of the tensioning rack drive block 63 drives the tensioning rack 32 directly or indirectly through a transition member 64. It should be noted that the transition member 64 may be a mechanical component with a transmission function, such as a gear ring or gear, and is not limited here. Furthermore, during the rotation of the second transmission component 61, the pawl 62 does not follow the rotation, but is instead driven by the third transmission unit 7, as will be described in detail below.

[0077] Preferably, the third transmission unit 7 includes a third transmission component 71 and a lower pressure block 72 that rotates synchronously with the third transmission component 71; the motor 1 drives the third transmission component 71 and drives the second transmission component 61 through the third transmission component 71; the tensioning module 3 also includes a ratchet 34 that rotates synchronously with the output wheel, and the ratchet 34 cooperates with the pawl 62; one end of the pawl 62 is provided with a rotating arm 621 that cooperates with the lower pressure block 72, and the other end is provided with a claw arm 622 that cooperates with the ratchet 34, wherein one side of the claw arm 622 is provided with a protrusion 6221 that cooperates with the ratchet 34, and the other side is provided with a spring 6222; the lower pressure block 72 drives the pawl 62 to rotate during the rotation process until the claw arm 622 disengages from the ratchet 34.

[0078] It should be noted that the motor 1 drives the second transmission component 61 through the third transmission component 71. During the rotation process, the third transmission component 71 drives the lower pressure block 72 to rotate synchronously. When the lower pressure block 72 rotates, it applies downward pressure to the rotating arm 621. The pawl 62 rotates under the downward pressure, driving the claw arm 622 to rotate. During the rotation process, the claw arm 622 compresses the spring and slowly disengages from the range of the ratchet 34. The entire process is completed when it is completely disengaged from the ratchet 34. At this time, the ratchet 34 can rotate freely. Since the output wheel rotates synchronously with the ratchet 34, that is, the output wheel can rotate freely at this time, the output wheel of the tensioning motor 33 is released. In addition, if the motor 1 stops outputting power, the pawl 62 rotates in the opposite direction due to the action of the spring 6222, and the output wheel of the tensioning motor 33 is locked again, and can only rotate in one direction.

[0079] Preferably, the first transmission component 51, the second transmission component 61 and the third transmission component 71 are all gears, the motor 1 is provided with a driving gear 11, the first transmission component 51, the driving gear 11, the third transmission component 71 and the second transmission component 61 are arranged in contact with each other in sequence; the welding motor 24 is provided with a welding driving wheel 25, and the toggle rod 22 is provided with a toggle tooth 222 that cooperates with the welding driving wheel 25.

[0080] It should be noted that the first transmission component 51, the second transmission component 61, and the third transmission component 71 can all be gears, and the first transmission component 51, the driving gear 11, the third transmission component 71, and the second transmission component 61 are sequentially arranged in a contact manner. In other words, the driving gear 11 can simultaneously drive the first transmission component 51, the second transmission component 61, and the third transmission component 71 to rotate. In addition, after the toggle tooth 222 contacts the teeth of the welding driving wheel 25, the welding driving wheel 25 can drive the toggle lever 22 to rotate.

[0081] The portable baler provided by the present invention includes a motor 1, a welding module 2, and a tensioning module 3, and includes a control module 4, a first transmission unit 5, and a second transmission unit 6. The motor 1 operates according to control signals from the control module 4. The motor 1 controls the raising and lowering of the welding upper tooth plate 21 of the welding module 2 via the first transmission unit 5. The motor 1 controls the spacing between the tensioning wheel 31 and the tensioning tooth plate 32 in the tensioning module 3 via the second transmission unit 6. By utilizing a single control module 4 and motor 1 to achieve the raising and lowering of the welding upper tooth plate 21 and control the spacing between the tensioning wheel 31 and the tensioning tooth plate 32, the portable baler of the present invention is not only simple and convenient to control, but also more labor-saving to operate, thus resolving the problems existing in the prior art.

[0082] Example 2, refer to Figures 11 to 18.

[0083] The present invention discloses a welding mechanism, which adopts the design of a control motor and a welding motor, and realizes the lifting of the welding upper tooth plate by driving a toggle rod. The control motor can drive the lifting of the welding upper tooth plate without additional operation, which can solve the defects of the existing technology.

[0084] The following is a clear and detailed description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Please refer to Figure 1, which shows the welding mechanism of the present invention, which is used in a portable baler and is connected to the control motor 1b in the portable baler, including: a toggle rod assembly and a welding motor assembly;

[0085] The toggle rod assembly includes a rotatable toggle rod 2b and a connecting member 3b, wherein one end of the toggle rod 2b is driven by the control motor 1b and is connected to the welding upper tooth plate 4b through the connecting member 3b, and the other end is rotated to be connected to the welding motor 5b of the welding motor assembly and then driven by the welding motor 5b.

[0086] In the present invention, the control motor 1b plays a guiding and controlling role. When the welding upper tooth plate 4b needs to be lifted, the control motor 1b drives the toggle rod 2b to rotate. During the rotation of the toggle rod 2b, the welding upper tooth plate 4b is driven to rise through the connecting member 3b. After one end of the toggle rod 2b is rotated to be connected to the welding motor 5b of the welding motor assembly, the welding motor 5b provides power to continue to drive the toggle rod 2b to rotate, that is, to continue to drive the welding upper tooth plate 4b to rise to the set position; after the control motor 1b completes the rise of the welding upper tooth plate 4b, the control motor 1b cuts off the output power between the control motor 1b and the toggle rod 2b, and the control motor 1b can be reversed to control the welding upper tooth plate 4b to descend, which is not limited here.

[0087] It should be noted that the control motor 1b of the present invention may be a servo motor, a steering gear, etc. In this embodiment, a steering gear is preferred and is not limited here.

[0088] Preferably, the welding motor assembly includes a welding motor 5b and a welding driving wheel 6b installed on the welding motor 5b; the toggle rod 2b is provided with a toggle tooth 21b that cooperates with the welding driving wheel 6b.

[0089] It should be noted that after the toggle rod 2b rotates to engage with the toggle tooth 21b and the welding driving wheel 6b, the welding motor 5b provides power for continued rotation. At this time, the control motor 1b no longer drives the toggle rod 2b.

[0090] Preferably, the toggle rod 2b is an L-shaped structure; the horizontal part of the L-shaped structure is connected to the welding upper tooth plate 4b through the connecting member 3b, and its vertical part is provided with a toggle tooth 21b; after the toggle rod 2b is rotated to contact the welding active wheel 6b, the welding upper tooth plate 4b, the connecting member 3b, the horizontal part of the toggle rod 2b, the vertical part of the toggle rod 2b and the welding active wheel 6b are connected in sequence.

[0091] In an embodiment of the present invention, the welding upper tooth plate 4b, the connecting member 3b, the horizontal portion of the toggle rod 2b, the vertical portion of the toggle rod 2b and the welding active wheel 6b are connected in sequence. Therefore, when the toggle rod 2b is driven by the control motor 1b to rotate, the horizontal portion of the toggle rod 2b pulls the welding upper tooth plate 4b to lift, and the vertical portion of the toggle rod 2b continuously approaches the welding active wheel 6b. After engaging with the welding active wheel 6b, the welding motor 5b provides power for continued rotation.

[0092] Preferably, movable seats are provided at both ends of the connecting member 3b, and the two movable seats are respectively connected to the transverse portion and the welded upper tooth plate 4b.

[0093] Preferably, the control motor 1b drives the toggle rod 2b through the first transmission unit 7b; the first transmission unit 7b includes a first transmission component 71b and a cam 72b driven by the control motor 1b, and the first transmission component 71b rotates synchronously with the cam 72b; one end of the toggle rod 2b is provided with a protrusion 22b that cooperates with the cam 72b, and the other end cooperates with the welding motor 5b.

[0094] In an embodiment of the present invention, the control motor 1b can control the toggle rod 2b through the first transmission unit 7b. Specifically, the control motor 1b drives the first transmission component 71b to rotate. Since the first transmission component 71b rotates synchronously with the cam 72b, the cam 72b rotates at the same time and abuts against the protrusion 22b. The protrusion 22b is displaced by the force, thereby driving the toggle rod 2b to rotate.

[0095] Preferably, the control motor 1b is provided with a driving gear 11b, and the first transmission component 71b is a gear matched with the driving gear 11b; the first transmission component 71b is coaxially arranged with the cam 72b.

[0096] Preferably, the control motor 1b operates according to a control signal sent by a control module 8b provided in the portable baler.

[0097] It should be noted that the driving gear 11b can not only cooperate with the first transmission component 71b, but also include other transmission components that cooperate at the same time. If there are multiple transmission components that cooperate with the driving gear 11b at the same time, then the control motor 1b can realize multiple functions at the same time, that is, after receiving the control signal sent by the control module 8b, it can realize multiple operating processes simultaneously or sequentially, which is not limited here.

[0098] Preferably, the control module 8b includes an operating handle 81b with a reset design and a control switch 82b, wherein the control switch 81b is triggered by pulling the operating handle 82b.

[0099] In the present invention, the control module 8b is preferably a combination of an operating handle 81b with a reset design and a control switch 82b, wherein the operating handle 81b has the advantage of being easy to operate and can greatly improve the user's operating feel.

[0100] Preferably, the portable baler consists of a working area 001b, a handle operation area 002b and a power supply area 003b connected in sequence; the operating handle 81b is arranged in the handle operation area 002b, or is arranged in the working area 001b and extends to the handle operation area 002b, and is arranged at a position suitable for operation by the index finger and / or middle finger when holding the handle 0021b.

[0101] It should be noted that when the control module 8b includes an operating handle 81b, the operating handle 81b can be a smaller and shorter handle. After this small handle is set under the handle 0021b, it is very convenient for the user to operate with the index finger and / or middle finger when lifting the portable baler to work, and a good operating feel can be obtained, which is completely different from the existing large handle that requires the portable baler to be put down or the other hand to be used to vigorously pull it.

[0102] Preferably, the operating handle 81b includes a pulling part 811b, a rotating part 812b and a control part 813b, wherein the control part 813b is used to trigger the control switch 82b; the rotating part 812b and the control part 813b are arranged in the working area 001b through the makeshift groove 0011b opened on the working area 001b, and the pulling part 811b extends from the makeshift groove 0011b to the bottom of the handle 0021b; the rotating part 812b is provided with a torsion spring 83b for controlling the reset of the operating handle 81b; the control switch 82b is an induction switch.

[0103] It should be noted that when the index finger or / and middle finger, generally the index finger, pulls the trigger part 811b, the operating handle 81b rotates, and after the control part 813b leaves the control switch 82b, the control switch 82b sends a control signal, and the control motor 1b will work according to the control signal.

[0104] The welding mechanism provided by the present invention is used in a portable baler and is connected to the control motor 1b in the portable baler, and includes: a toggle rod assembly and a welding motor assembly; the toggle rod assembly includes a rotatable toggle rod 2b and a connecting member 3b, wherein one end of the toggle rod 2b is driven by the control motor 1b and is connected to the welding upper tooth plate 4b through the connecting member 3b, and the other end is rotated to be connected to the welding motor 5b of the welding motor assembly and then driven by the welding motor 5b. The design of the control motor 1b and the welding motor 5b is adopted, and the lifting of the welding upper tooth plate 4b is achieved by driving the toggle rod 2b. The welding mechanism of the present invention can drive the lifting of the welding upper tooth plate 4b by the control motor 1b without performing additional operations, which can solve the defects of the existing technology.

[0105] The portable baler provided by the present invention is introduced in detail above. For those skilled in the art, according to the concept of the embodiments of the present invention, there may be changes in the specific implementation and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
