[0043] The core of this application is to disclose a packaging device to reduce labor intensity and improve production efficiency.

[0044] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0045] This application discloses a packaging device, including a fabric placement assembly 100, a frame, a compression assembly 200, a first packaging assembly 300, a second packaging assembly 400, a third packaging assembly 500, a laying assembly 700, and a sealing assembly 600. The packaging device disclosed in this application is mainly used for packaging lyocell fibers. The lyocell fibers are blown into the cotton drop box 220 of the compression assembly 200 by other equipment, and compressed by the compression assembly 200 to form a cuboid-like structure. For ease of description, the fibers to be packaged will be referred to as the fibers to be packaged below.

[0046] The system includes a fabric placement component 100 for placing fabric, a compression component 200 mounted on the frame for compressing the fibers to be packaged, a first packaging component 300 mounted on the frame and cooperating with the fabric placement component 100 for laying the fabric covering the top surface of the fibers to be packaged, a second packaging component 400 mounted on the frame and cooperating with the fabric placement component 100 for laying the fabric covering the sides of the fibers to be packaged, a third packaging component 500 mounted on the frame and cooperating with the fabric placement component 100 for laying the fabric covering the bottom surface of the fibers to be packaged, and a laying component 700 mounted on the frame. Figure 6 As shown, the laying machine assembly 700 includes a first heat-sealing mechanism 710, which is vertically and flexibly mounted on the laying machine assembly 700. It is used to cut fabric of suitable size. The first heat-sealing mechanism 710 can be a heat-sealing device known in the art, such as an electric heating wire cutter, a hot air knife, or an ultrasonic cutting device. The sealing assembly 600 is used for heat-sealing the edges of the fibers to be packaged.

The lifting mechanism 720 can be a screw-nut mechanism, a linear motor, or a piston cylinder; the specific type is not limited.

[0047] In actual use, the third packing component 500 cooperates with the cloth placement component 100 to lay the lower cloth at the bottom of the cotton drop box 220. The laying machine component 700 heat-melts and cuts the lower cloth. Subsequently, the fibers are blown into the cotton drop box 220 by other equipment. The first packing component 300 cooperates with the cloth placement component 100 to lay the upper cloth at the top of the cotton drop box 220. The laying machine component 700 heat-melts and cuts the upper cloth. The compression component 200 compresses the fibers to be packed, so that the upper cloth and the lower cloth... The wrapping cloths are located at the top and bottom of the fibers to be packaged. Then, the second packaging component 400 cooperates with the wrapping cloth placement component 100. The laying component 700 heat-melt cuts the middle wrapping cloth and lays the middle wrapping cloth on the side of the fibers to be packaged. After the upper wrapping cloth, lower wrapping cloth and middle wrapping cloth are laid, the fibers are conveyed to the sealing component 600. The sealing component 600 heat-melt seals the edges of the fibers that have been covered with wrapping cloth. After the heat-melt sealing, the fibers are conveyed to the end and can be stored by forklift.

[0048] The packaging device disclosed in this application comprises a cloth placement component 100, a first packaging component 300, a second packaging component 400, a third packaging component 500, a laying machine component 700, and a sealing component 600, which work together to perform upper, middle, and lower cloth wrapping operations on the fibers to be packaged. Furthermore, the sealing component 600 heat-seales the edges of the fibers to be packaged, thereby reducing labor intensity and improving production efficiency.

[0049] In some specific embodiments, in order to avoid reconnecting the fabric after it melts, a fabric pressing mechanism is provided on the laying machine assembly 700. Specifically, the fabric pressing mechanism may include a pressing plate or a pressing rod capable of pressing the fabric. A cylinder is provided on the laying machine assembly 700, and the piston rod of the cylinder is connected to the pressing plate or the pressing rod. The fabric passes through the lower space of the pressing plate or the pressing rod and is connected to the first packaging assembly 300 or the third packaging assembly 500 respectively. When the first packaging assembly 300 or the third packaging assembly 500 is working, the pressing plate or the pressing rod is in a raised state. When the fabric is about to melt, the pressing plate or the pressing rod presses down to press down the tail end of the fabric, so that the fabric does not need to be reconnected in the next operation.

[0050] In some specific embodiments, such as Figure 1 As shown, the fabric placement assembly 100 includes a fabric roll 110, a fabric pressure roller 120, and a rotating roller 130. The fabric of the fabric roll 110 passes through the gap between the fabric pressure roller 120 and the rotating roller 130. The first packaging assembly 300, the second packaging assembly 400, and the third packaging assembly 500 can be connected to the fabric respectively. The fabric placement assembly 100 includes a fixed base, and the fabric roll 110, the fabric pressure roller 120, and the rotating roller 130 are rotatably mounted on the fixed base.

[0051] In some specific embodiments, such as Figure 2As shown, the compression assembly 200 includes a base 210, a cotton drop box 220, and a pressure head 230. The base 210 is mounted on the frame, and the pressure head 230 is movably mounted on the base 210. Preferably, the pressure head 230 is connected to a linear drive mechanism to achieve lifting and lowering of the pressure head 230. The linear drive mechanism can be a cylinder, hydraulic cylinder, linear motor, electric push rod, etc., and the specific type can be selected according to actual needs. The cotton drop box 220 is provided with a first clamping mechanism 221 and a second clamping mechanism. The first clamping mechanism 221 is movably mounted on the base 210, and the second clamping mechanism is movably mounted on the pressure head 230. The first clamping mechanism 221 and the second clamping mechanism are used to clamp the upper and lower wrapping fabrics, respectively. The movable mounting of the first clamping mechanism 221 and the second clamping mechanism can adapt to the position of the fibers to be packaged, and adapt to the positions of the first packaging assembly 300, the second packaging assembly 400, and the third packaging assembly 500. Specifically, the lifting and lowering of the first clamping mechanism 221 can be driven by drive components such as piston cylinders and linear motors, and the lifting and lowering of the second clamping mechanism can be achieved by drive components such as linear motors and piston cylinders.

[0052] In some specific embodiments, the cotton dropping box 220 includes a first base, a first driving mechanism, and a second clamping mechanism. The second clamping mechanism includes at least four clamping parts, preferably four clamping parts, which are preferably evenly arranged along the circumference of the first base in a rectangular structure. The first driving mechanism is connected to the second clamping mechanism and is used to drive the at least four clamping parts to move synchronously along the radial direction of the first base. Specifically, taking four clamping parts as an example, the first driving mechanism can be a combination of a drive motor and a gear and rack mechanism. The gear is preferably a spur gear, which is rotatably mounted on the first base. The drive motor drives the gear to rotate. The rack corresponds one-to-one with the clamping parts, including four racks, each clamping part being connected to the rack.

[0053] Four racks are arranged in a cross shape on the same horizontal plane, all meshing with the central gear. This drives the motor, causing two oppositely arranged clamping parts to move simultaneously towards or away from the gear, thus achieving synchronous opening and closing of all clamping parts. It should be noted that the above method is only one embodiment; other solutions can also be used to achieve synchronous opening and closing of the four clamping parts.

[0054] Based on the above embodiments, the lifting and lowering of the second clamping mechanism can be achieved by a linear drive mechanism such as a linear motor, a pneumatic cylinder, or a hydraulic cylinder. The linear drive mechanism can be connected to the first base to achieve synchronous lifting and lowering of the four clamping parts.

[0055] In actual use, when the fiber to be packaged falls onto the lower cover of the cotton drop box 220, the upper cover is already laid out. The four clamping parts of the second clamping mechanism open simultaneously, that is, each clamping part moves away from the limit of the fiber to be packaged, and then descends simultaneously, so that the part of the upper cover extending to the side of the fiber to be packaged is spread out. Then the four clamping parts move simultaneously towards the fiber to be packaged, so that each clamping part abuts against the fiber to be packaged through the upper cover, so that the side of the upper cover abuts against the fiber to be packaged.

[0056] In some specific embodiments, the base 210 is provided with a second driving mechanism, which drives the first clamping mechanism 221 to rise and fall. Specifically, the first clamping mechanism 221 is connected to the base 210 via a linkage mechanism, which can be connected to a linear drive mechanism. The linear drive mechanism includes, but is not limited to, cylinders, hydraulic cylinders, and electric push rods. The fixed end of the linear drive mechanism is connected to the base 210, and the output end of the linear drive mechanism is hinged to the linkage mechanism. The movement of the linear drive mechanism realizes the rising and falling of the first clamping mechanism 221. A limiting element is provided on the base 210 to limit the displacement of the linkage mechanism, thereby limiting the upward displacement of the first clamping mechanism 221. The limiting element includes, but is not limited to, a stop.

[0057] Preferably, the frame is equipped with a slide rail extending vertically, and the cotton drop box 220 is equipped with a slider that slides with the slide rail. The slide rail and the slider cooperate to guide the lifting and lowering of the cotton drop box 220. The base 210 is equipped with at least one guide cylinder, which extends in the same vertical direction as the slide rail. The cotton drop box 220 is equipped with a guide shaft that cooperates with the guide cylinder, and the guide shaft is slidably inserted into the guide cylinder.

[0058] In some specific embodiments, such as Figure 3 As shown, the first packaging assembly 300 includes a second base 310, a first cloth clamping part 320 and a third drive mechanism. The second base 310 is connected to the frame. The first cloth clamping part 320 and the third drive mechanism are both disposed on the second base 310. The third drive mechanism is used to drive the first cloth clamping part 320 to reciprocate along the axial direction of the second base 310.

[0059] Specifically, the first fabric clamping part 320 includes a fabric clamp and a cylinder connected to the fabric clamp. The cylinder is used to drive the opening and closing of the fabric clamp to realize the fabric gripping function of the fabric clamp. The end of the piston rod of the cylinder is hinged to one end of a connecting rod. The fabric clamp is rotatably mounted on the base through a rotating shaft. The other end of the connecting rod is hinged to the fabric clamp, thereby converting the linear motion of the cylinder piston rod into the rotational motion of the fabric clamp around the rotating shaft, thus realizing the opening and closing of the fabric clamp.

[0060] The third drive mechanism includes a drive motor and a transmission mechanism connected to the drive motor. Specifically, the transmission mechanism can be a lead screw and nut mechanism, with the first fabric clamping part 320 connected to the nut, the nut threadedly connected to the lead screw, and the drive motor connected to the lead screw via a coupling; or the third drive mechanism can be an electric telescopic rod; or the third drive mechanism can be a linear motor or a piston cylinder, with the first fabric clamping part 320 including two fabric clamps connected together, the input end of the linear motor or piston rod connected to the second base 310, and the output end of the linear motor or piston rod connected to at least one fabric clamp.

[0061] In actual use, after the pressure head 230 of the compression assembly 200 rises to its position, the first fabric clamping part 320 clamps the fabric, and then the first fabric clamping part 320 shortens under the action of the third drive mechanism, that is... Figure 3 The first fabric clamping part 320 shown moves from left to right. When it moves to the appropriate position, the lifting mechanism in the laying machine assembly 700 rises, the first heat-melting mechanism 710 melts the fabric, and the upper fabric is laid to the second clamping mechanism.

[0062] In some specific embodiments, such as Figure 4 As shown, the third packing assembly 500 includes a third base 510, a second fabric clamping part 520, and a fourth drive mechanism. Both the second fabric clamping part 520 and the fourth drive mechanism are disposed on the third base 510. The fourth drive mechanism drives the second fabric clamping part 520 to reciprocate along the axial direction of the third base 510. The specific structure and connection method of the second fabric clamping part 520 and the fourth drive mechanism can be referenced from the first fabric clamping part 320 and the third drive mechanism, and will not be elaborated here.

[0063] In some specific embodiments, such as Figure 4 As shown, the third packaging assembly 500 includes a fork arm 530 and a fifth drive mechanism 540. The fixed end of the fifth drive mechanism 540 is hinged to the third base 510, and the fork arm 530 is rotatably mounted on the third base 510. The output end of the fifth drive mechanism 540 is hinged to the fork arm 530. The fifth drive mechanism is preferably a pneumatic cylinder or a hydraulic cylinder. The fork arm 530 can place the fiber to be packaged, after being covered with fabric, onto the conveyor belt.

[0064] In some specific embodiments, such as Figure 5As shown, the second packing assembly 400 includes a fourth base 410, a fabric clamping slider 420, a third fabric clamping part 430, a fourth fabric clamping part 440, and a fifth fabric clamping part 450. The fourth base 410 is disposed on the frame. The fabric clamping slider 420 is slidably disposed on the fourth base 410 along a first direction. The third fabric clamping part 430, the fourth fabric clamping part 440, and the fifth fabric clamping part 450 are slidably disposed on the fourth base 410 along a second direction, which is perpendicular to the first direction. The fourth fabric clamping part 440 includes a folding arm 441 for folding the fabric. In some specific embodiments, the fourth fabric clamping part 440 includes a main arm and a folding arm 441. The fabric clamp is disposed on the folding arm 441. The folding arm 441 is hinged to the main arm. The folding arm 441 is pushed by a cylinder. The fixed end of the cylinder is hinged to the main arm. The piston rod of the cylinder is hinged to the folding arm 441 to realize the folding action of the folding arm 441.

[0065] The first base of the cotton drop box 220 is equipped with a fabric covering limiter and a sixth drive mechanism that can drive the fabric covering limiter to extend and retract.

[0066] Preferably, the fourth fabric clamping part 440 and the fifth fabric clamping part 450 are both disposed on the movable trolley 470. The movable trolley 470 is movably disposed on the fourth base 410. The fourth base 410 is provided with a track that cooperates with the movable trolley 470. The movable trolley is connected to the fourth base 410 through a pulley 460. The track can provide a guiding function. The track is provided with limiters to limit the movement distance of the movable trolley 470. The limiters include, but are not limited to, blocks disposed on the track.

[0067] Specifically, in some embodiments, the third fabric clamping part 430 includes two fabric clamps connected together. The two fabric clamping parts 430 can be driven to move synchronously by a linear drive mechanism. The fourth base 410 is provided with a slide rail, and each third fabric clamping part 430 is provided with a slider that cooperates with the slide rail. Of course, the two third fabric clamping parts 430 can also be driven to move separately by two linear drive mechanisms.

[0068] Preferably, two fabric clamping sliders 420 are included. Each fabric clamping slider 420 can move along the first direction (the x-axis direction in the figure) on the fourth base 410 via a linear drive mechanism. The linear drive mechanism includes, but is not limited to, a linear motor, a piston cylinder, etc. The fabric clamping structure and principle of the fabric clamping slider 420 can be referred to the first fabric clamping part 320, and will not be repeated here. The fourth fabric clamping part 440 includes two fabric clamps arranged opposite each other, and the fifth fabric clamping part 450 includes two fabric clamps. The fourth fabric clamping part 440 and the fifth fabric clamping part 450 form an open rectangular structure. The moving trolley 470 can be driven to move along the second direction via a linear drive mechanism. The linear drive mechanism includes, but is not limited to, a linear motor, a piston cylinder, etc.

[0069] In actual use, when both the upper and lower wrapping fabrics are laid on the top and bottom surfaces of the fibers to be packaged, the second packaging component 400 activates. First, the first fabric clamping slider 420 clamps the wrapping fabric and moves along the first direction, causing the wrapping fabric to expand. When the fabric clamping slider 420 encounters the limiting member (including but not limited to a stop block) on the right side of the fourth base 410 along the first direction, it stops moving. Subsequently, the third wrapping fabric clamping part 430 moves along the second direction to... Figure 5 In front of the fourth base 410 shown, at the position of the guide rod where the fabric clamping slider 420 is located, the upper part of the wrapping fabric is clamped. The second fabric clamping slider 420 clamps the wrapping fabric, and the first fabric clamping slider 420 releases the wrapping fabric. The second packaging assembly 400 is provided with a second heat-sealing mechanism 480, which melts the wrapping fabric. This wrapping fabric is the middle wrapping fabric. Then the second fabric clamping slider 420 releases the wrapping fabric, and the third wrapping fabric clamping part 430 moves backward. Meanwhile, the moving trolley 470 moves backward. The fourth base 410 is provided with a limiting member for the moving trolley 470, including but not limited to a stop. When the moving trolley 470 moves to a preset position, it stops. The fourth and fifth fabric clamping parts 440 and 450 clamp the fabric, and the third fabric clamping part 430 releases. The moving trolley 470 carries the middle fabric forward and stops when it reaches the preset position. The folding arm 441 of the fourth fabric clamping part 440 folds so that the middle fabric covers all sides of the fiber to be packaged. It should be noted that the second heat-sealing mechanism 480 can be a welding and cutting device known in the art, such as an electric hot wire cutter, a hot air knife, or an ultrasonic cutting device. Alternatively, the first heat-sealing mechanism 710 can be used to cut the fabric.

[0070] Furthermore, to initially fix the wrapped fibers after the covering fabric has been laid, in some specific embodiments, a hot-melt spot welding mechanism can be used to perform preliminary spot welding with the middle covering fabric. Specifically, the hot-melt spot welding mechanism can be mounted on the folding arm 441. Before the covering fabric clamp on the folding arm 441 releases the covering fabric, the hot-melt spot welding mechanism operates to spot weld the middle covering fabric to achieve preliminary fixation. Specifically, the hot-melt spot welding mechanism includes a driving component, a welding head connected to the output end of the driving component, a heating element for heating the welding head, and a control unit. The driving component (such as a cylinder) is fixedly mounted on the upper clamping arm of the covering fabric clamp, with its piston rod extending downwards, and the welding head mounted at the end of the piston rod. When spot welding is required, the control unit controls the driving component to push the welding head downwards to press the covering fabric, while simultaneously controlling the heating element to heat the welding head, causing the covering fabric to partially heat-melt bond together, so that the middle covering fabric is heat-fused together with the upper and lower covering fabrics respectively. The heating element specifically includes, but is not limited to, a heating rod. It should be noted that the specific structure and installation method of the above-mentioned hot melt spot welding mechanism are only one embodiment and can be adapted to meet actual needs.

[0071] In the initial state, the fabric-covering limiting member retracts into the first base, with its top end lower than or flush with the fabric-covering working surface to facilitate smooth fabric laying. Once the fabric is in place, the sixth drive mechanism activates, causing the fabric-covering limiting member to pop out and protrude from the fabric-covering working surface, thereby securing the edge of the fabric and fixing it in place. Specifically, the sixth drive mechanism may include a cylinder, with its piston rod connected to the fabric-covering limiting member. The extension and retraction of the piston rod control the extension and retraction of the fabric-covering limiting member. It should be noted that multiple fabric-covering limiting members are included, preferably at least two on each side of the fiber to be packaged, respectively positioned on the upper and lower sides of the fiber to secure the laid fabric.

[0072] In some specific embodiments, such as Figure 7 As shown, the sealing assembly 600 includes a conveying mechanism 610 and a hot melt machine 620, with the hot melt machine 620 positioned on the conveying mechanism 610. The third packaging assembly 500 conveys the fibers to be packaged, with the upper, lower, and middle covering fabrics laid out, to the location of the hot melt machine 620. The hot melt machine 620 performs hot melt sealing on the upper, lower, and middle covering fabrics. The conveying mechanism 610 is equipped with a sensor. When the sensor detects that the workpiece has reached the hot melt station, the controller sends a signal to the hot melt machine 620. Specifically, the controller is configured to stop the conveying mechanism 610 in response to receiving a detection signal indicating that the workpiece to be packaged has reached the hot melt station; subsequently, the controller controls the hot melt machine 620 to perform the hot melt operation; after the hot melt operation is completed, the controller controls the conveying mechanism 610 to restart. It should be noted that the specific structure of the hot melt machine 620 here refers to existing hot melt machines and will not be described in detail here.

[0073] The packaging device disclosed in this application operates on the following principle: The second cloth clamping part 520 of the third packaging component 500 clamps the cloth extending from the cloth placement component 100. The cloth is laid on the first clamping mechanism 221 of the cotton drop box 220 of the compression component 200 by the extension and retraction of the second cloth clamping part 520. When the cloth is laid to a preset size, the first heat-sealing mechanism 710 of the laying machine component 700 cuts the cloth, completing the lower cloth laying. The fibers to be packaged are fed to the cotton drop box 220 by other equipment. The pressure head 230 of the compression component 200 reciprocates to compress the fibers until they reach a preset shape. The first cloth clamping part 320 of the first packing component 300 clamps the cloth extending from the cloth placement component 100. The cloth is opened by the extension and retraction of the first cloth clamping part 320 and laid on the second clamping mechanism of the cotton drop box 220 of the compression component 200. When the cloth is laid to the preset size, the first heat-melting mechanism 710 of the laying machine component 700 cuts the cloth, and the upper cloth is laid. Then, each clamping part of the second clamping mechanism moves synchronously away from the fiber to be packed, and after descending, moves synchronously towards the fiber to be packed until each clamping part abuts against the fiber to be packed, so that the side of the upper cloth is laid.

[0074] Then, the second packaging component 400 operates, with its fabric clamping slider 420 clamping the fabric extending from the fabric placement component 100. One of the clamping sliders 420 slides along the fourth base 410, opening the fabric. The third fabric clamping part 430 advances, clamps the fabric, and then retracts. The fourth and fifth fabric clamping parts 440 and 450 clamp the fabric, and the third fabric clamping part 430 releases. The fourth and fifth fabric clamping parts 440 and 450 together define an opening for receiving the fiber to be packaged. The moving trolley 470 advances, surrounding the side of the fiber to be packaged with the middle fabric. The folding arms 441 of the first and second clamping arms fold, so that the middle fabric at the opening is laid on the side of the fiber to be packaged. Subsequently, the fabric limiting member extends, locking the edge of the fabric, and the hot-melt spot welding mechanism hot-melts and fixes the fabric. The fork arm of the third packaging component 500 extends and sends the fibers with the wrapped fabric to the conveying mechanism 610. When the fibers reach the position of the hot melt machine 620, the hot melt machine completes the hot melt of the wrapped fabric, and the packaging is completed.
