The structure is simple and the limiting effect is good, which effectively improves the moving stability of the packaging device, avoids the packaging device from shaking during movement and causing damage to the packaging head or dislocation of parts, and ensures the packaging accuracy of the packaging head.

[0030] 3. The filling head in the powder filling and adjusting equipment provided by the present invention is equipped with a weighing mechanism. The weighing mechanism installs the storage box through a weighing plate, and supports and fixes the weighing plate through a weighing sensor. The weighing sensor can accurately detect the overall weight of the storage box on the weighing plate. Since the weight of the storage box is fixed, the weight of the powder in the storage chamber can be accurately calculated, and then the amount of powder reduction during each filling operation can be accurately detected, which is more conducive to accurately controlling the filling amount. At the same time, it can also detect the remaining powder in the storage chamber in real time, which is convenient for timely adding powder and avoiding material shortages.

[0031] 4. The filling head in the powder filling and adjusting equipment provided by the present invention includes a filling mechanism and a stirring mechanism. The filling mechanism is independently driven by a first motor to rotate a filling screw to perform a filling operation, and the stirring mechanism is independently driven by a second motor to rotate a stirring element along the periphery of the filling screw to perform a stirring operation. The two do not interfere with each other. The filling operation and the stirring operation can be performed independently or simultaneously, and can be adapted to more application scenarios. When the powder in the receiving chamber is blocked, the stirring element can be started in time to break it up, thereby ensuring the filling effect and filling accuracy.

[0032] 5. The filling head in the powder filling and adjusting equipment provided by the present invention includes a feeding hopper, a feeding cover and an opening mechanism. When the powder remaining amount in the receiving chamber of the receiving box is lower than the preset value, the opening mechanism can automatically drive the feeding cover to rotate and open relative to the feeding hopper, so that the relevant operators can judge on site which filling head is short of material, so as to achieve the purpose of timely reminder to add materials and facilitate subsequent powder adding operations. At the same time, due to the provision of the feeding hopper, the feeding port can be expanded on the limited space on the top surface of the receiving box, which is more convenient for adding powder and avoids powder spilling.

[0033] 6. The film feeding device in the powder packaging and adjusting equipment provided by the present invention adopts a movable structure. The film feeding mechanism can be quickly pulled out by sliding with the movable frame and the guide slide bar, and the position of the film feeding mechanism can be changed, so that the film feeding mechanism is not interfered with by other devices, which is convenient for adding film rolls, thereby eliminating the need to place the film feeding device as a whole externally. While being convenient to use, it makes the structural layout of the powder packaging and adjusting equipment more reasonable and compact, and is more conducive to miniaturized design. The movable frame is pressed and fixed by a quick-release clamp, which ensures the positioning accuracy and stability of the film feeding mechanism, while the positioning and fixing operation is more convenient and quick, and the use is highly convenient.

[0049] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0050] Figures 1 to 11 The present invention provides a powder packaging and adjustment device, which is used to automatically complete the powder packaging and adjustment operation, improve the powder packaging speed and packaging accuracy, and is more conducive to ensuring the temperature, humidity and air cleanliness conditions of the packaging and adjustment environment, thereby effectively avoiding contamination of the powder.

[0051] Please combine Figure 1 、 Figure 2 and Figure 3 The powder packaging and dispensing equipment 1000 includes a frame 1, and a guide device 2, a packaging device 3, a film feeding device 4 and a bag making device 5 respectively arranged on the frame 1. The packaging device 3 is installed on the guide device 2 and is used to slide along the guide device 2 to change its position. The film feeding device 4 is used to transport film to the bag making device 5. The bag making device 5 is used to make the film transported by the film feeding device 4 into a packaging bag. The packaging device 3 is used to pack a preset dose of powder into the packaging bag, thereby realizing the fully automated operation of film feeding, bag making and packaging in sequence, improving the efficiency of powder packaging and dispensing, and ensuring the accuracy of the packaging dose.

[0052] like Figure 4 As shown, the guiding device 2 includes a fixed guide rail 21 and a folding guide rail 22 hinged to the fixed guide rail 21. The packaging device 3 is arranged on the fixed guide rail 21. The folding guide rail 22 is used to rotate relative to the fixed guide rail 21 to an expanded state or a folded state. The expanded state of the folding guide rail 22 is on the extension line of the fixed guide rail 21 and docked with the fixed guide rail 21, so that the packaging device 3 can slide along the fixed guide rail 21 to the folding guide rail 22, effectively increasing the position adjustment stroke of the packaging device 3, and facilitating the packaging device 3 to be pulled out of the frame 1 as a whole. The folded state of the folding guide rail 22 is at a preset angle relative to the fixed guide rail 21, so that the folding guide rail 22 can be folded and stored in the frame 1 when not in use, thereby realizing the folding and hiding of the folding guide rail 22.

[0053] Since the guide device 2 includes a fixed guide rail 21 and a folding guide rail 22, the folding guide rail 22 can be rotated to the extension line of the fixed guide rail 21 and docked with the fixed guide rail 21, so that the packaging device 3 can be moved along the fixed guide rail 21 to the folding guide rail 22, so that the packaging device 3 can be pulled out as a whole, and the position of the packaging device 3 can be changed, so that the packaging device 3 is not interfered with by other devices, which is convenient for repair and maintenance of the packaging device 3, and also convenient for adding powder to the packaging head 30 on the packaging device 3, and the folding guide rail 22 can also be rotated to a folded state with a preset angle relative to the fixed guide rail 21, so as to be folded and hidden, so that the overall structure of the powder packaging and adjusting equipment 1000 is more compact and miniaturized, effectively reducing the occupied space.

[0054] Preferably, the guide device 2 further includes a support rod 23 hingedly connected to the folding guide rail 22. The support rod 23 is configured to rotate to a position supporting the folding guide rail 22 when the folding guide rail 22 is in the unfolded state, and further configured to rotate to a position parallel to the folding guide rail 22 when the folding guide rail 22 is in the folded state. When the folding guide rail 22 is in the unfolded state, the support rod 23 can be pulled out to support and fix the folding guide rail 22, thereby improving the stability of the folding guide rail 22. When the folding guide rail 22 is in the folded state, the support rod 23 can be rotated to a position in contact with the folding guide rail 22, thereby folding and concealing the support rod 23.

[0055] Please combine Figure 1 and Figure 2 The guide device 2 also includes a positioning seat 24, which is installed on the frame 1 and has a positioning slot 241. The first end of the support rod 23 is hinged to the folding guide rail 22, and the second end of the support rod 23 is used to rotate to a state embedded in the positioning slot 241 when the folding guide rail 22 is in the unfolded state, so as to quickly position and fix the support rod 23, avoid the support rod 23 from loosening and causing the folding guide rail 22 to shake, and improve the supporting strength and stability of the support rod 23.

[0056] exist Figure 4 As shown in the figure, the second end of the support rod 23 is provided with a flexible rubber pad 231. The flexible rubber pad 231 is used to be embedded in the positioning groove 241 when the folding guide rail 22 is in the unfolded state. The flexible rubber pad 231 is also used to abut the folding guide rail 22 when the folding guide rail 22 is in the folded state. The support rod 23 can achieve an elastic buffering effect by cooperating with the positioning groove 241 or the folding guide rail 22 through the flexible rubber pad 231, thereby avoiding rigid collisions, protecting the folding guide rail 22 and the positioning seat 24, and improving the quiet effect.

[0057] Preferably, the support rod 23 includes a first support rod 232, a second support rod 233 sleeved on the first support rod 232 and configured to telescopically move relative to the first support rod 232, and a locking member configured to lock the second support rod 233 relative to the first support rod 232. In other words, the support rod 23 adopts a telescopic structure, allowing its support length to be flexibly adjusted, thereby flexibly adjusting the horizontality of the folding guide rail 22 according to the actual use site, so that the folding guide rail 22 is precisely docked with the fixed guide rail 21 under the support and fixation of the support rod 23.

[0058] Preferably, the support rod 23 is disposed at the bottom of the folding guide rail 22, and a fixing slot (not shown in the figure, the same below) is provided on the folding guide rail 22 for embedding the support rod 23. When the folding guide rail 22 is in the folded state, the support rod 23 can be rotated until it is embedded in the fixing slot, which not only strengthens the fixation of the support rod 23 but also further hides the support rod 23, so that the support rod 23 and the folding guide rail 22 become one.

[0059] Please combine Figure 2 and Figure 4 The folding guide rail 22 is provided with a positioning post 221. The positioning post 221 is used to be inserted into a positioning hole (not shown in the figure, the same below) preset in the frame 1 when the folding guide rail 22 is in the folded state, thereby fixing the folding guide rail 22 to the frame 1. The positioning post 221 is also used to abut the packaging device 3 when the folding guide rail 22 is in the unfolded state, thereby limiting the maximum sliding stroke of the packaging device 3 on the folding guide rail 22 and preventing the packaging device 3 from slipping off the folding guide rail 22. That is, the positioning post 221 can simultaneously achieve the positioning and fixing function of the folding guide rail 22 and the travel limiting function of the packaging device 3, with a simple structure and good positioning effect.

[0060] Furthermore, the fixed guide rails 21 are arranged in parallel in a plurality, and the folding guide rails 22 are arranged in a one-to-one correspondence with the fixed guide rails 21. The guide device 2 supports the sub-packaging device 3 through the plurality of fixed guide rails 21 and guides the sub-packaging device 3 to slide, thereby effectively improving the stability of the sub-packaging device 3.

[0061] Furthermore, the guide device 2 also includes a connecting rod 25 arranged between two adjacent folding guide rails 22 and connecting the two adjacent folding guide rails 22 into a whole. It can not only improve the stability of the folding guide rail 22, but also connect multiple folding guide rails 22 into a whole in sequence, so as to facilitate driving multiple folding guide rails 22 to rotate to the unfolded state or the folded state at the same time.

[0062] like Figure 4 As shown, the guide device 2 also includes a horizontal limiting wheel 261 mounted on the side of the fixed guide rail 21 and a vertical limiting wheel 262 mounted above the fixed guide rail 21. The horizontal limiting wheel 261 is used to abut the side of the base 31 of the packaging device 3 and roll along the side of the base 31 when the base 31 slides, and the vertical limiting wheel 262 is used to abut the top surface of the base 31 and roll along the top surface of the base 31 when the base 31 slides.

[0063] Since the guide device 2 includes a horizontal limiting wheel 261 and a vertical limiting wheel 262, the horizontal limiting wheel 261 abuts against the side of the base 31 and rolls along the side of the base 31 when the base 31 slides, and the vertical limiting wheel 262 abuts against the top surface of the base 31 and rolls along the top surface of the base 31 when the base 31 slides, the packaging device 3 can be limited in the horizontal and vertical directions respectively. The structure is simple and the limiting effect is good, which effectively improves the moving stability of the packaging device 3, avoids the packaging device 3 from shaking during movement and causing damage to the packaging head 30 or dislocation of parts, and ensures the packaging accuracy of the packaging head 30.

[0064] Preferably, the guide device 2 includes a plurality of limiting wheel groups 26 spaced apart along the length direction of the fixed guide rail 21, and the limiting wheel groups 26 include a pair of horizontal limiting wheels 261 and a pair of vertical limiting wheels 262 disposed between the pair of horizontal limiting wheels 261. The pair of horizontal limiting wheels 261 and the pair of vertical limiting wheels 262 together constitute a limiting wheel group 26, so that the limiting wheel group 26 can mutually clamp and fix the base 31 under the cooperation of four limiting wheels, effectively improving the stability of the base 31 at the position corresponding to the limiting wheel group 26. At the same time, since there are multiple limiting wheel groups 26, the base 31 can be clamped and fixed from multiple positions on the base 31.

[0065] More preferably, the distance between two adjacent limiting wheel sets 26 along the length direction of the fixed guide rail 21 is smaller than the length of the base 31, so that the base 31 abuts at least two of the limiting wheel sets 26 in the length direction, further enhancing the stability of the base 31.

[0066] Furthermore, two fixed guide rails 21 are provided side by side, and the limiting wheel group 26 is mounted on the side of the fixed guide rail 21 away from the other fixed guide rail 21. The limiting wheel group 26 is provided on both fixed guide rails 21. By arranging the limiting wheel group 26 on the outer sides of the two fixed guide rails 21, the two relative limiting wheel groups 26 can jointly clamp and fix the base 31 in the horizontal direction, thereby fixing the base 31 on the fixed guide rail 21.

[0067] Please combine Figure 4 and Figure 5 The guide device 2 further includes a limit plate 27 provided on the fixed guide rail 21, and the limit plate 27 is used to abut the end of the base 31 to limit the movement stroke of the base 31 along its length direction.

[0068] Preferably, a limiting hole 271 is provided on the limiting plate 27 , and the limiting hole 271 is used to insert a limiting column 34 preset on the base 31 to strengthen the fixation of the base 31 and improve the stability of the base 31 .

[0069] Preferably, the limiting plate 27 is further provided with a pin hole 272 in a direction perpendicular to the limiting hole 271, and the guiding device 2 also includes a limiting pin 28 passed through the pin hole 272, and the limiting pin 28 is used to be inserted into the limiting groove 341 preset on the periphery of the limiting column 34, so that the axial limitation of the limiting groove 341 is achieved through the plug-in cooperation between the limiting pin 28 and the limiting groove 341, thereby achieving the limiting fixation of the entire packaging device 3.

[0070] Preferably, the guide device 2 also includes a reset spring (not shown in the figure, the same below), which is used to apply an elastic force to the limit pin 28 in the direction toward the limit hole 272 to prevent the limit pin 28 from loosening by itself. At the same time, when the base 31 drives the limit column 34 to move into the limit hole 271, the reset spring drives the limit pin 28 to automatically insert into the limit groove 341, thereby realizing automatic locking of the packaging device 3.

[0071] Please combine Figure 2 and Figure 6 The packaging device 3 includes a base 31 and a plurality of packaging head modules 32 arranged side by side on the base 31 along the length direction of the base 31. The packaging head module 32 includes a sliding seat 321 arranged on the base 31 and used to slide relative to the base 31 along the width direction of the base 31, and a plurality of packaging heads 30 arranged side by side on the sliding seat 321 along the width direction of the base 31.

[0072] Since the packaging device 3 is composed of a plurality of packaging head modules 32, not only can the packaging device 3 as a whole be pulled out along the length direction of the base 31, but a single packaging head module 32 can also be pulled out along the width direction of the base 31. The packaging device 3 is split into multiple modules, and any one of the packaging head modules 32 can be pulled out for repair, maintenance, and powder addition operations, effectively avoiding positional interference between two adjacent packaging head modules 32, making it more convenient and quick to use.

[0073] like Figure 6As shown, the packaging head module 32 further includes a fixed seat 322 provided on the base 31 and a limiter 323 connected to the fixed seat 322. The sliding seat 321 is mounted on the fixed seat 322 and is used to slide along the fixed seat 322. The limiter 323 is used to abut against the sliding seat 321 and lock the sliding seat 321 relative to the fixed seat 322. The limiter 323 locks the sliding seat 321 to the fixed seat 322, ensuring the stability of the sliding seat 321 during the packaging operation and preventing the sliding seat 321 from sliding automatically.

[0074] Preferably, the limiting member 323 is rotatably mounted on the fixed seat 322, and the limiting member 323 is used to rotate relative to the fixed seat 322 to a state of abutting or disengaging from the sliding seat 321, that is, the sliding seat 321 can be locked or unlocked by swinging the limiting member 323, which is convenient and quick to use.

[0075] Preferably, a plurality of slide rails are arranged side by side on the fixed seat 322, and the sliding seat 321 is arranged on the slide rails and is used to slide along the slide rails. By simultaneously supporting and fixing the sliding seat 321 and guiding the sliding seat 321 to slide, the stability and movement accuracy of the sliding seat 321 can be improved.

[0076] Preferably, the dispensing head module 32 further includes a dust suction pipe 324 mounted on the fixing base 322. The dust suction pipe 324 includes a connection hole 3241 for connecting a vacuum cleaner and a plurality of dust suction holes (not shown, the same below) respectively connected to the connection hole 3241. The dust suction holes are arranged in a one-to-one correspondence with the plurality of dispensing heads 30 on the dispensing head module 32. During use, a vacuum cleaner can be used to suck away dust between the dispensing heads 30 and the packaging bags through the dust suction holes on the dust suction pipe 324, thereby improving the cleanliness of the powder dispensing and adjusting environment. Moreover, since the dust suction pipe 324 is provided with a plurality of dust suction holes corresponding to the plurality of dispensing heads 30, dust removal operations can be performed simultaneously at multiple dispensing stations, thereby ensuring dust removal effect and improving dust removal efficiency.

[0077] Furthermore, the dispensing head module 32 is detachably connected to the base 31 and / or the dispensing head 30 is detachably connected to the sliding seat 321, which facilitates the separate disassembly and assembly of any one of the dispensing head modules 32 or any one of the dispensing heads 30, improves the convenience of maintenance, and facilitates the cleaning of the dispensing head 30.

[0078] exist Figure 2As shown in the figure, the bottom of the base 31 is provided with rollers 33, which are used to support the base 31 and drive the base 31 to move. Specifically, the rollers 33 are embedded in the fixed guide rails 21 and are used to cooperate with the fixed guide rails 21 to drive the base 31 to move along the length of the base 31. The guide device 2 is adapted to the rollers 33. Because the base 31 needs to be equipped with multiple filling head modules 32, the overall weight is relatively large and the movement resistance is relatively large. In this case, the configuration of the rollers 33 can improve the smoothness of the movement of the filling device 3 relative to the guide device 2, making it more convenient and labor-saving to use.

[0079] exist Figure 5 As shown in the figure, the base 31 is provided with a limiting column 34 at the end along its length direction. The limiting column 34 is used to be inserted into the limiting hole 271. The base 31 is limited and fixed by the mutual cooperation between the limiting column 34 and the limiting hole 271.

[0080] Preferably, a limiting groove 341 for inserting the limiting pin 28 is opened on the outer periphery of the limiting column 34, and the base 31 is strengthened and fixed by the mutual cooperation between the limiting groove 341 and the limiting column 34 to prevent the base 31 from sliding on its own.

[0081] Please combine Figure 7 and Figure 8 The dispensing head 30 includes a receiving box 301 and a weighing mechanism 302 . A receiving cavity 3011 is provided inside the receiving box 301 . A dispensing hole 3012 communicating with the receiving cavity 3011 is opened at the bottom of the receiving box 301 .

[0082] Preferably, the weighing mechanism 302 includes a weighing plate 3021 and a weighing sensor 3022, the storage box 301 is installed on the weighing plate 3021, the weighing sensor 3022 supports and fixes the weighing plate 3021, and the weighing sensor 3022 is used to detect the weight of the storage box 301 on the weighing plate 3021, thereby detecting the weight of the powder in the storage cavity 3011.

[0083] Since the filling head 30 is equipped with a weighing mechanism 302, the weighing mechanism 302 installs the storage box 301 through the weighing plate 3021, and supports and fixes the weighing plate 3021 through the weighing sensor 3022. The weighing sensor 3022 can be used to accurately detect the overall weight of the storage box 301 on the weighing plate 3021. Since the weight of the storage box 301 is fixed, the weight of the powder in the receiving chamber 3011 can be accurately calculated, and the reduction amount of powder during each filling operation can be accurately detected, which is more conducive to accurately controlling the filling amount. At the same time, the remaining powder in the receiving chamber 3011 can be detected in real time, which is convenient for timely adding powder to avoid material shortage.

[0084] Preferably, the weighing plate 3021 is provided with a mounting hole 3021a in a vertical direction, and the storage box 301 is fixedly mounted in the mounting hole 3021a. The weighing plate 3021 is vertically mounted and fixed to the storage box 301 through the mounting hole 3021a. This not only stably supports the storage box 301, but also prevents interference with the upper and lower ends of the storage box 301. This facilitates adding powder from the top of the storage box 301 and dispensing from the bottom of the storage box 301. Furthermore, the weight of the storage box 301 is measured vertically, making the detection structure more accurate and reliable, and less susceptible to influences from other factors.

[0085] Preferably, the storage box 301 includes a cylindrical section and a conical section coaxially arranged in the vertical direction. The conical section is located below the cylindrical section and together with the cylindrical section, encloses the storage cavity 3011. The conical section is inserted and fixed in the mounting hole 3021a. The conical section reduces the space occupied by the storage box 301 on the weighing plate 3021, thereby facilitating the reduction of the weighing plate 3021 and preventing the weighing mechanism 302 from protruding too far from the storage box 301. This makes the structural layout of the dispensing head 30 more reasonable and compact. At the same time, the diversion effect of the conical section can be used to improve the flow smoothness of the powder during the dispensing operation and prevent powder blockage.

[0086] In this embodiment, only one load cell 3022 is provided. By supporting and fixing the weighing plate 3021 with one load cell 3022, the weight of the powder in the receiving chamber 3011 can be accurately detected. In other embodiments, multiple load cells 3022 can be provided, and the multiple load cells 3022 are arranged at intervals around the receiving box 301 and connected to the weighing plate 3021. By jointly supporting and fixing the weighing plate 3021 with the multiple load cells 3022, the stability of the weighing plate 3021 can be effectively improved, thereby improving the installation stability of the receiving box 301, preventing the receiving box 301 from shaking, and further improving the accuracy of the weighing and packaging operations.

The filling mechanism 303 includes a first motor 3031 provided on the top of the storage box 301 and a filling screw 3032 connected to the output shaft of the first motor 3031. The outer diameter of the filling screw 3032 is adapted to the inner diameter of the filling hole 3012.

[0088] Preferably, the stirring mechanism 304 includes a second motor 3041, a transmission assembly 3042 and a stirring member 3043. The second motor 3041 is arranged side by side with respect to the first motor 3031. The first end of the transmission assembly 3042 is connected to the second motor 3041, and the second end of the transmission assembly 3042 is connected to the stirring member 3043. The stirring member 3043 is arranged in the accommodating cavity 3011 and is sleeved on the outer periphery of the packaging screw 3032. The stirring member 3043 is used to rotate relative to the packaging screw 3032 under the drive of the second motor 3041.

[0089] Since the packaging head 30 includes a packaging mechanism 303 and a stirring mechanism 304, the packaging mechanism 303 is independently driven by the first motor 3031 to rotate the packaging screw 3032 for packaging operations, and the stirring mechanism 304 is independently driven by the second motor 3041 to rotate the stirring element 3043 along the periphery of the packaging screw 3032 for stirring operations. The two do not interfere with each other, and the packaging operation and the stirring operation can be carried out independently or simultaneously, which can be adapted to more application scenarios. When the powder in the receiving chamber 3011 is blocked, the stirring element 3043 can be started in time to break it up, thereby ensuring the packaging effect and packaging accuracy.

[0090] Preferably, the stirring member 3043 and the packaging screw 3032 rotate in opposite directions. The stirring member 3043 and the packaging screw 3032 rotate in different directions respectively, which can better disrupt and disperse the powder in the receiving chamber 3011, avoid powder blockage, and effectively improve the stirring effect.

[0091] Preferably, the output shaft of the first motor 3031 and the filling screw 3032 are both arranged on the central axis of the storage box 301, the second motor 3041 is arranged on one side of the first motor 3031, and the transmission assembly 3042 includes a first gear 3042a and a second gear 3042b that are meshed with each other, the first gear 3042a is connected to the output shaft of the second motor 3041, the second gear 3042b is connected to the stirring member 3043, the second gear 3042b is coaxially arranged relative to the filling screw 3032 and can rotate relative to the filling screw 3032, so that under the drive of the first motor 3031, the first gear 3042a, the second gear 3042b and the stirring member 3043 are driven to rotate in sequence, and the rotation of the stirring member 3043 and the filling screw 3032 do not interfere with each other.

[0092] Preferably, the stirring mechanism 304 further includes a first bearing 3044 and a second bearing 3045 respectively sleeved on the dispensing screw 3032, the second gear 3042b is mounted on the first bearing 3044, and the stirring member 3043 is mounted on the second bearing 3045. The first bearing 3044 and the second bearing 3045 improve the rotational stability and smoothness of the stirring member 3043.

[0093] Preferably, the stirring member 3043 includes a plurality of stirring rods spaced apart along the circumference of the dispensing screw 3032 , and the shapes of the plurality of stirring rods are the same or different to meet different stirring requirements.

[0094] Preferably, the stirring rod includes a first segment 3043a and a second segment 3043b arranged in sequence along the axial direction of the filling screw 3032, and the spacing of the first segment 3043a relative to the filling screw 3032 and the spacing of the second segment 3043b relative to the filling screw 3032 are different, so that different positions can be stirred respectively by the first segment 3043a and the second segment 3043b, thereby improving the stirring effect.

[0095] More preferably, the first segments 3043a of two adjacent stirring rods have different spacings relative to the packaging screw 3032, and / or the second segments 3043b of two adjacent stirring rods have different spacings relative to the packaging screw 3032, so as to further optimize the stirring position and achieve sufficient stirring.

[0096] Preferably, a plurality of stirring rods are arranged equidistantly along the circumference of the packaging screw 3032 to improve the circumferential stability of the stirring element 3043 and avoid the center of gravity of the stirring element 3043 being misplaced to affect the stirring effect.

[0097] Preferably, the filling head 30 further includes a motor bracket 305 provided on the top of the storage box 301 , and the first motor 3031 and the second motor 3041 are both mounted on the motor bracket 305 to strengthen the fixation of the first motor 3031 and the second motor 3041 .

[0098] like Figure 7 As shown, the packaging mechanism 303 also includes a code disk 3033 and a slot-type photoelectric switch (not shown in the figure, the same below). The code disk 3033 is arranged on the top of the storage box 301 and is coaxially connected to the packaging screw 3032. The slot-type photoelectric switch is arranged on one side of the code disk 3033. The code disk 3033 is provided with a plurality of detection holes 3033a equidistantly arranged along its circumference. The code disk 3033 is used to be driven by the packaging screw 3032 to rotate synchronously and make the plurality of detection holes 3033a pass through the detection position of the slot-type photoelectric switch in sequence during rotation.

[0099] Since the first motor 3031 and the sub-packaging screw 3032 are connected by a coupling, they are prone to loosening after long-term use, which may cause the first motor 3031 to be unable to drive the sub-packaging screw 3032 to rotate, affecting the sub-packaging accuracy. At this time, the code disk 3033 and the slot-shaped photoelectric switch cooperate to detect the rotation state of the sub-packaging screw 3032 in real time, which can avoid timely judgment of whether the sub-packaging screw 3032 is rotating and detect the rotation angle of the sub-packaging screw 3032. Secondly, the coordinated cooperation of the code disk 3033 and the slot-shaped photoelectric switch can also be used for sub-packaging origin detection to improve sub-packaging accuracy.

[0100] Preferably, the packaging mechanism 303 also includes an angle sensor connected to the output shaft of the first motor 3031 and used to detect the rotation angle of the output shaft of the first motor 3031, so as to accurately detect the rotation angle of the packaging screw 3032, accurately detect the packaging amount, and improve the packaging accuracy.

[0102] Since the filling head 30 includes a feeding hopper 306, a feeding cover 307 and a cover opening mechanism 308, when the powder remaining in the receiving chamber 3011 of the receiving box 301 is lower than a preset value, the feeding cover 307 can be automatically driven by the cover opening mechanism 308 to rotate and open relative to the feeding hopper 306, so that the relevant operator can judge on site which filling head 30 is short of material, so as to achieve the purpose of timely reminder to add materials and facilitate subsequent powder adding operations. At the same time, since the feeding hopper 306 is provided, the feed port 3061 can be expanded on the limited space on the top surface of the receiving box 301, which is more convenient for adding powder and avoids powder spilling.

[0103] Preferably, the lid opening mechanism 308 includes a lock catch 3081 rotatably mounted on the feeding hopper 306, a lock hook 3082 provided on the feeding cover 307 and interlocked with the lock catch 3081, a lid opening drive assembly 3083 for driving the lock catch 3081 to rotate and disengage from the lock hook 3082, and a first elastic member 3084 connected to the feeding cover 307. The first elastic member 3084 is used to apply an elastic force to the feeding cover 307 in the opening direction of the feeding cover 307. When the lid opening drive assembly 3083 drives the lock catch 3081 to rotate and disengage from the lock hook 3082, the feeding cover 307 automatically springs open under the elastic force of the first elastic member 3084.

[0104] Furthermore, the cover opening mechanism 308 also includes a second elastic member (not shown in the figure, the same below) connected to the lock buckle 3081, and the second elastic member is used to apply an elastic force to the lock buckle 3081 along the fastening direction of the lock buckle 3081, so that after the cover opening drive component 3083 disengages from the lock buckle 3081, the lock buckle 3081 is driven by the second elastic member to maintain the state of fastening the lock hook 3082, thereby ensuring the locking strength. At the same time, it can also automatically fasten and lock the feeding cover 307 after the feeding cover 307 is rotated to close, thereby realizing a self-locking effect.

[0107] Furthermore, the cover opening drive assembly 3083 includes a telescopic electromagnet 3083a and a hook 3083b connected to the telescopic electromagnet 3083a.

[0108] Preferably, the cover opening mechanism 308 is electrically connected to the weighing sensor 3022 and is used to drive the feeding cover 307 to rotate and open relative to the feeding hopper 306 when the detection value of the weighing sensor 3022 is lower than a preset value. Automatic opening of the cover when the material is insufficient is realized, which is convenient for reminding relevant personnel to add powder.

The film feeding mechanism 44 is used to feed a film to the bag making device 5.

[0110] Since the film feeding device 4 adopts a movable structure, the film feeding mechanism 44 can be quickly pulled out by sliding cooperation between the movable frame 42 and the guide slide 41, and the position of the film feeding mechanism 44 can be changed, so that the film feeding mechanism 44 is not interfered with by other devices, which facilitates the addition of film rolls, thereby eliminating the need to place the film feeding device 44 as a whole externally, making it convenient to use, and making the structural layout of the powder packaging and dispensing equipment 1000 more reasonable and compact, and more conducive to miniaturized design. The movable frame 42 is pressed and fixed by the quick-release clamp 43, ensuring the positioning accuracy and stability of the film feeding mechanism 44, while making the positioning and fixing operations more convenient and quick, and highly easy to use.

Reverse self-locking is achieved while quickly pressing and fixing to prevent loosening.

[0112] Furthermore, the pressure head assembly 432 includes a pressure head seat 4321 and a lifting assembly 4322 arranged on the pressure head seat 4321, and a pressure head 4323 connected to the lifting assembly 4322. The lifting assembly 4322 is used to adjust the height of the pressure head 4323 in the vertical direction so that the pressure head 4323 can fully adapt to the movable frame 42 to ensure the pressing strength.

[0113] Furthermore, the lifting assembly 4322 includes a screw rod passed through the pressure head seat 4321 and a nut threadedly matched with the screw rod. One end of the screw rod is connected to the pressure head 4323, and the other end of the screw rod passes through the pressure head seat 4321 and is connected to the nut. Driving the nut to rotate can drive the screw rod to move up and down, thereby driving the pressure head 4323 to move up and down, and flexibly adjusting the height of the pressure head 4323.

[0114] Preferably, the movable frame 42 is provided with a plurality of pressure head positioning grooves (not shown in the figure, the same below) spaced apart along its sliding direction, and the pressure head positioning grooves are adapted to the pressure head assembly 432 and are used for positioning and pressing the pressure head assembly 432, so as to enhance the pressing strength of the pressure head assembly 432 on the movable frame 42 and realize the positioning and fixation of the movable frame 42, so as to facilitate fixing the movable frame 42 to a preset position, such as a normal use position and a position for convenient replacement of the film.

[0115] Furthermore, the film feeding device 4 also includes a pressure plate 45 which is detachably arranged above the guide slide 41 and together with the guide slide 41 forms a slide groove. The movable frame 42 is embedded in the slide groove and is used to slide along the slide groove. The movable frame 42 is fixed in the vertical direction by the pressure plate 45 to prevent the movable frame 42 from tipping over relative to the guide slide 41.

[0116] Preferably, a first limiting bolt 423 is mounted on the movable frame 42, and a second limiting bolt 451 is mounted on the side wall of the pressure plate 45. The bolt head of the second limiting bolt 423 is used to abut against the bolt head of the first limiting bolt 451 when the movable frame 42 slides to the limit position, thereby limiting the sliding stroke of the movable frame 42. The sliding stroke of the movable frame 42 can be limited by the mutual cooperation between multiple bolts, and the limiting structure is simple, efficient, and low-cost.

[0117] Preferably, the movable frame 42 includes a bottom plate 421 arranged in the horizontal direction and a side plate 422 connected to one side of the bottom plate 421 and extending upward in the vertical direction.

There are two guide slides 41, namely a first guide slide 411 provided on the side of the bottom plate 421 away from the side plate 422 and a second guide slide 412 provided on the side of the bottom plate 421 close to the side plate 422. The pressing plate 45 and the quick-release clamp 43 are both provided on the first guide slide 411.

[0118] Since the center of gravity of the film feeding mechanism 44 is located on the side of the side plate 422 away from the bottom plate 421, the first guide slide 411 is fixed by the pressure plate 45 and the quick-release clamp 43, so that the movable frame 42 can be kept balanced, with a simple structure and good stability.

[0119] Furthermore, the film feeding mechanism 44 includes a film feeding roller (not shown, the same below) rotatably mounted on a side of the side plate 422 away from the bottom plate 421, and a film feeding drive assembly 441 mounted on a side of the side plate 422 facing the bottom plate 421. The film feeding roller is used to wind a film roll, and the film feeding drive assembly 441 is connected to the film feeding roller and is used to drive the film feeding roller to rotate, thereby achieving film feeding. By respectively arranging the film feeding roller and the film feeding drive assembly 441 on opposite sides of the side plate 422, the overall force on the side plate 422 is balanced, and the stability is good. No additional support structure is required, which is more conducive to simplifying the structure, reducing costs, and reducing the space occupied by the film feeding device 4.

[0120] Preferably, the film feeding mechanism 44 also includes a film missing detection component 442, which uses a photoelectric switch.
