Description

Technical Field

[0001] The present invention relates to the technical field of packaging equipment, and in particular to a warm baby packaging machine. Background Art

[0002] The warm baby packaging machine is a device for producing warm baby, which can automatically complete the packaging processes of warm baby such as bag making, filling and sealing. As the market demand for warm baby increases, the market scale of warm baby packaging machine is also growing due to its own characteristics.

[0003] There is no mandatory standard for the weight of existing hot packs, so each manufacturer adjusts the weight of the product according to the market share and their own segmentation direction. For hot packs with small weight or small particle dosage, the production can be completed if the existing hot pack packaging machine is used. However, the operator found that since the unloading component of the existing hot pack packaging machine usually uses the sliding form between the unloading table and the hopper to unload the material, this causes the granular material to slide on the surface of the unloading table. Once it has been used for a long time, scratches are found on the surface of the unloading table. Once there are particles in these scratches, it will further cause a jam between the hopper and the unloading table. This jam will lead to an increase in the friction between the hopper and the unloading table. The increase in friction is likely to cause new scratches. This problem cannot be solved by applying lubricating oil.

[0004] Therefore, a new warm baby packaging machine is in urgent need of. Summary of the invention

[0005] The present invention provides a warm baby packaging machine, which solves the problem of scratches on the surface of the unloading table due to relative sliding between the unloading table and the hopper in the existing warm baby packaging machine in the prior art.

[0006] The technical solution of the present invention is as follows: a warm baby packaging machine, comprising:

[0007] frame;

[0008] A first unwinding assembly, disposed on the frame and having a first packaging cloth in a rolled shape;

[0009] A material discharge assembly is arranged on the frame, the material discharge assembly comprises a material discharge platform, a hopper, a material discharge bracket, a material discharger and a scraper, the material discharge platform is arranged on the frame in a vertical direction, the hopper is arranged on the material discharge platform, a material discharge hole is arranged on the material discharge platform, a material discharge port of the material discharge platform is connected with the material discharge hole of the material discharge platform, the material discharge bracket is arranged on the frame, the material discharger is arranged on the material discharge bracket, the material discharger penetrates into the hopper and blocks the material discharge port of the hopper by means of the movement of the material discharge platform, the scraper is arranged on the frame and used to spread the piled granular material, and the scraper is arranged at a distance from the first packaging cloth in motion;

[0010] A second unwinding assembly, disposed on the frame and having a rolled second packaging cloth;

[0011] A heat sealing assembly, disposed on the frame and used to seal the granular material between the first packaging cloth and the second packaging cloth;

[0012] A traction assembly, disposed on the frame and used for traction of the first packaging cloth and the second packaging cloth to move;

[0013] A rolling and cutting assembly is arranged on the frame and is used to cut the packaged warm baby into slices;

[0014] A conveying assembly, arranged on the frame and used to convey the sheet-shaped warm baby out of the frame;

[0015] A winding assembly, arranged on the frame and used for collecting the remaining material after cutting;

[0016] A controller, which is disposed on the frame and electrically connected to the first unwinding assembly, the unloading assembly, the second unwinding assembly, the heat sealing assembly, the traction assembly, the rolling and cutting assembly, and the winding assembly;

[0017] Among them, after the unloading platform moves upward, the unloading device blocks the discharge port of the hopper, and after the unloading platform moves downward, the unloading device avoids the discharge port of the hopper.

[0018] As a further technical solution, in two independent vertical planes perpendicular to the moving direction of the first packaging cloth, the projections of the hopper are respectively rectangular and trapezoidal, and the size of the hopper inlet is larger than the size of the hopper outlet, and the feeder is rectangular.

[0019] As a further technical solution, the material discharge assembly also includes a sealing ring, which is sleeved on the outside of the material discharger and is used to cooperate with the material discharger to seal the discharge port of the hopper.

[0020] As a further technical solution, the feeder assembly further includes a guide plate, which is bent and disposed on the back of the feeder, and the bending portion of the guide plate is away from the back of the feeder.

[0021] As a further technical solution, the thickness of the hopper discharge port is equal to or less than the thickness of the feeder.

[0022] As a further technical solution, the hopper and the feeder are both multiple and arranged in one-to-one correspondence.

[0023] As a further technical solution, the plurality of hoppers are symmetrically distributed, and the symmetry plane is a vertical plane.

[0024] As a further technical solution, the blanking assembly further includes a height adjusting member, and the height adjusting member includes:

[0025] An adjustment bracket is arranged on the frame and is provided with a first adjustment hole;

[0026] An adjustment plate is arranged on the scraper plate and is provided with a second adjustment hole, wherein the first adjustment hole and the second adjustment hole are arranged coaxially;

[0027] An adjusting bolt is inserted into both the first adjusting hole and the second adjusting hole;

[0028] An adjusting nut, sleeved on the end of the adjusting bolt;

[0029] Wherein, the scraper adjusts the distance between itself and the moving first packaging cloth by means of the height adjusting member.

[0030] As a further technical solution, the surface of the scraper facing the hopper is composed of a first inclined surface and a second inclined surface, the first inclined surface faces the first packaging cloth, and the second inclined surface faces away from the first packaging cloth.

[0031] As a further technical solution, the first unwinding assembly, the unloading assembly, the second unwinding assembly, the traction assembly, the rolling and cutting assembly and the conveying assembly are arranged in sequence along the moving direction of the first packaging cloth.

[0032] The working principle and beneficial effects of the present invention are as follows: the first packaging cloth enters the unloading assembly with the help of the first unwinding assembly and the traction assembly. When the unloading platform descends, the discharge port of the hopper and the unloader are separated. The granular material in the hopper can fall onto the first packaging cloth under the action of gravity. When the unloading platform rises, the unloader will block the discharge port of the hopper, thereby preventing the granular material from entering the first packaging cloth again. At this time, the first packaging cloth will move under the guidance of the traction assembly. During the movement, the scraper will spread the accumulated granular material, which is convenient for subsequent heat sealing operations. Before heat sealing, the second packaging cloth enters the heat sealing assembly from the second unwinding assembly. The second packaging cloth is located above the spread granular material, and then the first packaging cloth and the second packaging cloth are bonded in the heat sealing assembly. After bonding, it enters the rolling and cutting assembly to complete cutting. After cutting, a sheet-shaped warm baby finished product and residual material are formed. The sheet-shaped warm baby finished product will enter the conveying assembly, and the residual material will enter the winding assembly. Since the material unloading method of the present invention is a relative movement form of the unloader and the hopper, the movement of the granular material on the unloading platform is avoided. Therefore, it can not only avoid the granular material from scratching the surface of the unloading platform, but also avoid the granular material from blocking between the hopper and the unloading platform, causing the two to get stuck. In addition, since the granular material no longer slides a long distance, the noise during unloading can be reduced, the comfort of the working environment and the user's experience are improved, and the production efficiency of the warm baby will eventually be improved. The scraper set on the unloading platform and the heat sealing component can turn the accumulated granular material on the first packaging cloth into flat granular material, thereby improving the heat sealing efficiency and reducing the defective rate.

[0055] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0056] like Figures 1 to 11 As shown, this embodiment proposes a warm baby packaging machine, including:

[0057] Rack 1;

[0058] A first unwinding assembly 2, which is disposed on the frame 1 and has a first packaging cloth in a rolled form;

[0059] The unloading assembly 3 is arranged on the frame 1. The unloading assembly 3 includes an unloading platform 301, a hopper 302, an unloading bracket 303, a unloader 304 and a scraper 305. The unloading platform 301 is arranged on the frame 1 for movement in the vertical direction. The hopper 302 is arranged on the unloading platform 301. A feeding hole is arranged on the unloading platform 301. The discharge port of the hopper 302 is connected to the feeding hole of the unloading platform 301. The unloading bracket 303 is arranged on the frame 1. The unloader 304 is arranged on the unloading bracket 303. The unloader 304 penetrates into the hopper 302 and blocks the discharge port of the hopper 302 by means of the movement of the unloading platform 301. The scraper 305 is arranged on the frame 1 and is used to spread the piled granular material. The scraper 305 is arranged at a distance from the first packaging cloth in motion.

[0060] A second unwinding assembly 4, which is disposed on the frame 1 and has a second packaging cloth in a rolled shape;

[0061] A heat sealing assembly 5, disposed on the frame 1 and used to seal the granular material between the first packaging cloth and the second packaging cloth;

[0062] A traction assembly 6, disposed on the frame 1 and used for traction of the first packaging cloth and the second packaging cloth to move;

[0063] A rolling and cutting assembly 7 is arranged on the frame 1 and is used to cut the packaged warm baby into slices;

[0064] A conveying assembly 8, which is disposed on the frame 1 and is used to convey the sheet-shaped warm baby out of the frame 1;

[0065] A winding assembly 9, arranged on the frame 1 and used for collecting the remaining material after cutting;

[0066] A controller is arranged on the frame 1 and electrically connected to the first unwinding assembly 2, the unwinding assembly 3, the second unwinding assembly 4, the heat sealing assembly 5, the traction assembly 6, the rolling and cutting assembly 7 and the winding assembly 9;

[0067] Among them, after the unloading platform 301 moves upward, the unloading device 304 blocks the discharge port of the hopper 302, and after the unloading platform 301 moves downward, the unloading device 304 avoids the discharge port of the hopper 302.

[0068] In this embodiment, the hot baby packaging machine includes a frame 1, a first unwinding component 2, a blanking component 3, a second unwinding component 4, a heat sealing component 5, a traction component 6, a rolling and cutting component 7 and a conveying component 8 which are sequentially arranged on the frame 1, and a controller is arranged inside the frame 1, and the controller is electrically connected to the first unwinding component 2, the blanking component 3, the second unwinding component 4, the heat sealing component 5, the traction component 6, the rolling and cutting component 7 and the winding component 9 respectively.

[0069] The rack 1 includes a cabinet 101, a cabinet door 102 and a flat plate adjustment foot 103. The cabinet 101 is a common cubic shape, and a large space is provided inside the cabinet 101. The power accessories and the controller are placed inside the cabinet 101. The upper surface of the cabinet 101 is used for feeding, sealing, cutting and other operations of the warm baby. The flat plate adjustment foot 103 is provided below the cabinet 101 and is used to adjust the overall height so that the upper surface of the cabinet 101 can be in a horizontal plane.

[0070] The first unwinding assembly 2 includes a first winding roller 201, a first guide roller 202, a first tensioning roller 203, a first feeding roller 204 and a first auxiliary plate 205. The first auxiliary plate 205 is arranged on the frame 1 and protrudes to the front of the frame 1. The first winding roller 201 is rotatably arranged on the first auxiliary plate 205. The first winding roller 201 is used to place the rolled first packaging cloth. The first packaging cloth in the unfolded state passes through the first guide roller 202, the first tensioning roller 203 and the first feeding roller 204 in sequence, and then penetrates to the bottom of the unloading assembly 3 and is used to receive the granular material. There are multiple first guide rollers 202 and they are arranged on the first auxiliary plate 205. The first guide roller 202 is mainly used to spread the first packaging bag. The first tensioning roller 203 uses its own weight to tension the first packaging bag. Due to the existence of the first tensioning roller 203, the spread first packaging cloth will not be wrinkled, ensuring the yield rate. The first loading roller 204 is rotatably arranged on the frame 1 , and the upper surface of the first loading roller 204 is parallel to the upper surface of the frame 1 . The first packaging bag bypasses the upper surface of the first loading roller 204 and then enters the upper surface of the frame 1 , and then enters under the unloading component 3 .

[0071] The material unloading assembly 3 includes a material unloading platform 301, a hopper 302, a material unloading bracket 303, a material unloader 304 and a scraper 305. The material unloading platform 301 is arranged to slide in the vertical direction, the hopper 302 is arranged on the material unloading platform 301, and the hopper 302 moves in the vertical direction synchronously with the material unloading platform 301; the material unloading assembly 3 also includes a material unloading driving member, which is arranged in the frame 1 and has a material unloading driving end that moves in the vertical direction, and the material unloading platform 301 is arranged on the material unloading driving end, thereby realizing the reciprocating movement of the material unloading platform 301 in the vertical direction. The material unloading bracket 303 is arranged on the frame 1, the material unloader 304 is arranged on the material unloading bracket 303, and the material unloader 304 is inserted into the hopper 302. Since the material unloading bracket 303 is arranged on the frame 1, the material unloader 304 is immovable relative to the hopper 302. When the hopper 302 rises, the feeder 304 blocks the discharge port of the hopper 302, so that the granular material in the hopper 302 cannot be discharged from the discharge port; when the hopper 302 falls, the feeder 304 avoids the discharge port of the hopper 302, and the granular material in the hopper 302 can leave the hopper 302 under the action of gravity, and then flow into the surface of the first packaging bag. After completing the feeding action, the first packaging bag will move on the surface of the frame 1, and will encounter the scraper 305 during the movement. The scraper 305 will scrape the accumulated granular material flat, thereby achieving the leveling of the granular material. Since the scraper 305 is located above the first packaging bag and there is a certain distance between the two, the scraper 305 can push the accumulated granular material flat.

[0072] The hopper 302 and the unloading platform 301 are detachably connected and fixed by the bottom of the hopper 302. Since the granular material is relatively light and the hot baby packaging machine provided by the present invention is mainly used for hot baby with a small gram weight, the granular material in the hopper 302 is not large. In addition, the material of the hopper 302 is in the form of aluminum alloy, which is relatively light as a whole. The bottom-fixed connection method can increase stability.

[0073] It should be particularly noted that the material discharge bracket 303 has nothing special about it and does not involve the core invention point of the present invention. It is just a bracket for fixing the material discharger 304. Therefore, its structure will no longer be limited or described in detail.

[0074] The second unwinding assembly 4 includes a second winding roller 401 , a second guide roller 402 , a second tensioning roller 403 , a second loading roller 404 and a second auxiliary plate 405 . Among them, the second auxiliary plate 405 is arranged on the side of the frame 1, the second winding roller 401 is rotatably arranged on the second auxiliary plate 405, the second winding roller 401 is used to place the rolled second packaging cloth, the second guide roller 402 is arranged on the second auxiliary plate 405, and is located next to the second winding roller 401, the second tensioning roller 403 is L-shaped, and one end is rotatably arranged on the second auxiliary plate 405, the second feeding roller 404 is arranged on the frame 1, and is located between the scraper 305 and the heat sealing assembly 5. Since the rolled second packaging cloth is relatively large and in order to avoid interference between the second packaging cloth and the heat sealing assembly 5, the position of the second winding roller 401 is relatively high. At the same time, the positions of the second guide roller 402 and the second tensioning roller 403 are both relatively high. In order to allow the second packaging cloth to smoothly enter the heat sealing assembly 5 to complete the cooperation with the first packaging cloth and the granular material, the second feeding roller 404 is arranged on the upper surface of the frame 1.

[0075] The heat sealing assembly 5 includes a lifting and pressing platform 501, a heat sealing driving member, a heat sealing plate 502 and a heating member 503. The heat sealing driving member is arranged inside the frame 1 and is electrically connected to the controller, the lifting and pressing platform 501 is located outside the frame 1, the lifting and pressing platform 501 is connected to the driving end of the heat sealing driving member, the connecting member is arranged through the upper surface of the frame 1, the heat sealing plate 502 is arranged below the lifting and pressing platform 501, the heating member 503 is arranged above the lifting and pressing platform 501, and the heating member 503 is connected to the heat sealing plate 502. During the descending process of the lifting and pressing platform 501, the heat sealing plate 502 not only presses the second packaging cloth, the granular material and the first packaging cloth together, but also provides heat to the first packaging cloth and the second packaging cloth, thereby melting the glue between the first packaging cloth and the second packaging cloth and bonding them together, so that each granular material is isolated.

[0076] The traction assembly 6 includes a traction bracket 601, a traction wheel 602 and a traction drive. The traction bracket 601 is arranged on the frame 1, and the traction wheel 602 is rotatably arranged on the traction bracket 601. There are multiple traction wheels 602 and they are arranged side by side. The multiple traction wheels 602 are spaced at the same distance. The direction of the axis of the rotating shaft of the traction wheel 602 is perpendicular to the moving direction of the first packaging cloth. The traction wheel 602 and the upper surface of the frame 1 squeeze the uncut baby warmer in the middle, so that the uncut baby warmer can be powered, and then the first packaging bag and the second packaging bag can be powered indirectly. The traction drive is arranged on the frame 1 and is electrically connected to the controller. The output end of the traction drive is connected to the shaft of the traction wheel 602.

[0077] The rolling assembly 7 includes a rolling bracket 701, a rolling cutter 702, a rolling shaft 703 and a rolling driver. The rolling bracket 701 is arranged on the frame 1, the rolling shaft 703 is rotatably arranged on the rolling bracket 701, the rolling driver is arranged on the rolling bracket 701 and is electrically connected to the controller, the output shaft of the rolling driver is connected to the rolling shaft 703, the rolling cutter 702 is sleeved on the outside of the rolling shaft 703, and the rolling cutter 702 is used to cut out sheet-shaped warm baby.

[0078] The winding assembly 9 includes a winding roller 901, a winding drive, a winding guide roller 902 and a winding tension roller 903. The winding drive is arranged on the second auxiliary plate 405 and is electrically connected to the controller, the output end of the winding drive is connected to the end of the winding roller 901, the winding roller 901 is rotatably connected to the second auxiliary plate 405, the winding guide roller 902 is arranged on the second auxiliary plate 405, the winding tension roller 903 is L-shaped, and the end of one end is rotatably connected to the second auxiliary plate 405, when the combination of the first packaging cloth, the granular material and the second packaging cloth is cut, a sheet-shaped warm baby and residual material will be generated, and the residual material is in a mesh shape, and the mesh-shaped residual material can be wound around the winding guide roller 902 and the winding tension roller 903 and then wound on the winding roller 901, so that the normal collection of the residual material can be ensured, and defective products caused by unfavorable residual material collection can be avoided.

[0079] The conveying assembly 8 includes a conveyor belt and a conveyor motor. The conveyor motor is arranged inside the frame 1 and is electrically connected to the controller, and the conveyor belt is arranged on the frame 1, and is used to transfer the finished product warm baby.

[0080] It should be particularly noted that the main improvement of the present invention is the improvement of the unloading part of the hot packing machine, and also the improvement of the time parameters in the control program, and no improvement is made to other structures. Therefore, only some components of other structures are described, and no longer fully expanded. Technical personnel in this field can also accurately and completely reproduce the technical solutions recorded in the present invention based on the prior art.

[0081] The working principle of the warm baby packaging machine provided by the present invention is as follows: before starting the machine, the first packaging cloth and the second packaging cloth are manually pulled to the traction assembly 6, and the traction assembly 6 can guide the first coiling roller 201 and the second coiling roller 401 to discharge materials normally, and then start the machine normally. After starting the machine, when the unloading platform 301 descends in the vertical direction, since the unloading device 304 is not movable relative to the hopper 302, the unloading device 304 can avoid the discharge port of the hopper 302, so that the granular material enters the first packaging cloth, and when the unloading platform 301 rises in the vertical direction, the unloading device 304 will block the discharge port of the hopper 302, thereby preventing the granular material from entering the first packaging cloth from the hopper 302. When the granular material falls on the first packaging cloth, it will be placed in a pile, and then it will contact the scraper 305 under the moving traction of the first packaging cloth, and the scraper 305 will turn the piled granular material into a flat granular material. When the unloading platform 301 moves up and down, the lifting and pressing platform 501 will move synchronously. When the unloading platform 301 moves up, the first packaging cloth moves, and when the unloading platform 301 moves down, the first packaging cloth no longer moves. The lifting and pressing platform 501 will press the first packaging cloth and the second packaging cloth together. During the pressing process, heat will be transferred to the pressing part, and the pressing part will be heated to make the first packaging cloth and the second packaging cloth adhere together. The first packaging cloth, granular material and second packaging cloth combined into one are introduced into the rolling cutting component 7 through the traction component 6. After the rolling cutting component 7 completes the cutting and cutting, a sheet-shaped warm baby is formed, and then the sheet-shaped warm baby will enter the transmission component, and the remaining material after cutting will enter the winding component 9.

[0082] It should be particularly noted that the remaining material after cutting does not contain any granular material, but is merely a combination of the first packaging cloth and the second packaging cloth.

[0083] The main beneficial effects provided by the present invention are:

[0084] 1. The hopper 302 is arranged on the unloading platform 301, and the hopper 302 and the unloading platform 301 move synchronously in the vertical direction. The discharge port of the hopper 302 is connected with the feeding hole on the unloading platform 301. At this time, there is no mutual movement between the hopper 302 and the unloading platform 301, and there will be no wear and jamming of the granular material between the two; in addition, the unloading device 304 only blocks the hopper 302 when the unloading platform 301 rises to the maximum height, which can also avoid long-term contact between the unloading device 304 and the inside of the hopper 302, thereby reducing the wear of the unloading device 304 and the inside of the hopper 302.

[0085] Second, since the material is automatically dropped, and part of the discharge port of the hopper 302 will inevitably be blocked by the discharge device 304, the granular material dropped on the first packaging cloth is in an accumulated state, and the accumulated granular material will have a poor heat sealing effect due to the poor contact between the heat sealing plate 502 and the material to be sealed during heat sealing, so a scraper 305 is provided between the discharge table 301 and the heat sealing assembly 5. The scraper 305 can flatten the accumulated granular material, and then the granular material can be kept flat when entering the heat sealing assembly 5 along with the first packaging cloth, and then the second packaging cloth is also laid flat, and this state is when the heat sealing effect of the heat sealing assembly 5 is the best.

[0086] 3. The new unloading method and the linkage form of the scraper 305 can not only solve the problem that the surface of the unloading table 301 is always scratched and the sliding friction between the unloading table 301 and the hopper 302 is large, but also further solve the problem of granular material accumulation after the unloading method is changed, avoiding the defective rate in the heat sealing link.

[0087] Further, if Figures 9 to 11 As shown, this embodiment proposes that in two independent vertical planes perpendicular to the moving direction of the first packaging cloth, the projections of the hopper 302 are respectively rectangular and trapezoidal, and the size of the inlet of the hopper 302 is larger than the size of the outlet of the hopper 302, and the feeder 304 is rectangular.

[0088] In this embodiment, there are two vertical planes perpendicular to each other in the moving direction of the first packaging cloth, and the two vertical planes are independent, that is, the two vertical planes are perpendicular to each other, and both are perpendicular to the table of the frame 1, or both are perpendicular to the first packaging cloth, the projections of the hopper 302 on the two vertical planes are rectangular and trapezoidal respectively, and the size of the inlet of the hopper 302 is larger than the size of the outlet of the hopper 302, and the feeder 304 is rectangular at the same time. At this time, the two symmetrical planes of the feeder 304 are parallel to the two symmetrical inner wall surfaces of the hopper 302, or even close to each other; the other two symmetrical planes of the feeder 304 are not parallel to the other two symmetrical planes of the hopper 302. The outer edge size of the feeder 304 is only equal to the size of the outlet of the feeder 304, that is, only when the hopper 302 is at the highest position, the feeder 304 can completely seal the outlet of the hopper 302. Setting the hopper 302 and the feeder 304 to a conventional shape is conducive to reducing production costs.

[0089] Further, if Figure 6 As shown, this embodiment proposes that the material discharge assembly 3 also includes a sealing ring 306 , which is sleeved on the outside of the material discharger 304 and is used to cooperate with the material discharger 304 to seal the discharge port of the hopper 302 .

[0090] In this embodiment, in order to reduce the wear between the feeder 304 and the hopper 302 and to improve the sealing performance between the feeder 304 and the discharge port of the hopper 302, a sealing ring 306 is sleeved on the outside of the feeder 304. The sealing ring 306 directly contacts the inner wall of the hopper 302 and is made of a softer material such as rubber or silicone.

[0091] Further, if Figure 6 As shown, this embodiment proposes that the material discharge assembly 3 also includes a guide plate 307 , which is bent and arranged on the back of the material discharger 304 , and the bending part of the guide plate 307 is away from the back of the material discharger 304 .

[0092] In this embodiment, since the feeder 304 is arranged inside the hopper 302 and is likely to penetrate into the granular material, in order to prevent the granular material in the hopper 302 from being poked to the outside by the feeder 304 during the lifting process of the hopper 302, a guide plate 307 is arranged on the back of the feeder 304. The guide plates 307 are bent, there are two guide plates 307, and they are symmetrically arranged. The guide plates 307 cover as much of the back of the feeder 304 as possible, and the bend of the guide plate 307 is far away from the back of the feeder 304, that is, the bend of the guide plate 307 faces upward, and the bend of the guide plate 307 is higher than the rest of the guide plate 307 in vertical height. In this way, a triangular protrusion is formed on the back of the feeder 304, so that the granular material can smoothly leave the front (bottom) of the feeder 304 from the back (top) of the feeder 304.

[0093] Furthermore, this embodiment proposes that the thickness of the discharge port of the hopper 302 is equal to or smaller than the thickness of the discharge port 304 .

[0094] In this embodiment, in order to prevent the granular material from adhering to the discharge port of the hopper 302 when the material is dropped, the thickness dimension of the discharge port of the hopper 302 in the vertical direction is set to be equal to or less than the thickness of the feeder 304. In this way, it can be ensured that during the movement, the feeder 304 can fully push the granular material at the discharge port onto the first packaging cloth.

[0095] Further, if Figure 1 to Figure 5 As shown, this embodiment proposes that both the hopper 302 and the feeder 304 are multiple and arranged in one-to-one correspondence. The multiple hoppers 302 are symmetrically distributed, and the symmetry plane is a vertical plane.

[0096] In this embodiment, in order to improve the production efficiency of the hot pack, the hopper 302 and the feeder 304 are both set to be multiple, and are set in a one-to-one correspondence, that is, there is only one feeder 304 in one hopper 302, and the multiple hoppers 302 are set symmetrically, which can reduce the occupied space, and the vertical plane is the symmetrical plane.

[0097] In a practical application, there are four hoppers 302 and four feeders 304. The four hoppers 302 are arranged in double rows and double columns.

[0098] Further, if Figures 5 to 8 As shown, this embodiment proposes that the blanking assembly 3 also includes a height adjustment member, and the height adjustment member includes:

[0099] An adjustment bracket 308 is disposed on the frame 1 and is provided with a first adjustment hole;

[0100] The adjustment plate 309 is arranged on the scraper plate 305 and has a second adjustment hole, and the first adjustment hole and the second adjustment hole are arranged coaxially;

[0101] The adjusting bolt 310 is inserted into the first adjusting hole and the second adjusting hole at the same time;

[0102] An adjusting nut, sleeved on the end of the adjusting bolt 310;

[0103] The scraper 305 adjusts the distance between itself and the moving first packaging cloth by means of a height adjusting member.

[0104] In this embodiment, since the granular material will accumulate after being dropped, the scraper 305 can change the accumulated granular material into a flat granular material, thereby improving the yield rate of the heat sealing process. In order to adjust the thickness of the flat granular material, the unloading assembly 3 also includes a height adjustment member, which includes an adjustment bracket 308, an adjustment plate 309, an adjustment bolt 310 and an adjustment nut. Among them, the adjustment bracket 308 is set on the frame 1, and a first adjustment hole is opened on the adjustment bracket 308, the scraper 305 is set on the adjustment plate 309, and a second adjustment hole is opened on the adjustment plate 309. The first adjustment hole and the second adjustment hole are coaxially arranged, and the adjustment bolt 310 is inserted into the first adjustment hole and the second adjustment hole at the same time. The adjustment nut is sleeved on the adjustment bolt 310, and the adjustment bolt 310 contacts the adjustment plate 309, and the adjustment nut contacts the adjustment bracket 308. In this way, the height of the adjustment plate 309 can be changed by rotating the adjustment bolt 310, thereby changing the height of the scraper 305.

[0105] Further, if Figure 8 As shown, this embodiment proposes that the surface of the scraper 305 facing the hopper 302 is composed of a first inclined surface and a second inclined surface, the first inclined surface faces the first packaging cloth, and the second inclined surface faces away from the first packaging cloth.

[0106] In this embodiment, in order to reduce the resistance of the scraper 305 when spreading the material, the surface of the scraper 305 facing the hopper 302 is set to consist of two inclined surfaces, a first inclined surface and a second inclined surface, and the intersection of the first inclined surface and the second inclined surface faces the granular material scattered on the first packaging cloth, the first inclined surface faces the first packaging cloth, and the second inclined surface faces away from the first packaging cloth. When in use, only the first inclined surface can touch the granular material, or both the first inclined surface and the second inclined surface can touch the granular material, which can be adjusted according to the height of the granular material.

[0107] It should be noted that the accumulated granular materials falling from the hopper 302 are in the shape of long strips. Two accumulated granular materials fall from one hopper 302 . There is a certain interval between the two accumulated granular materials. When passing through the scraper 305 , the two accumulated granular materials will be evenly formed into a layer of granular materials.

[0108] Further, if Figure 1-2 As shown, this embodiment proposes that the first unwinding assembly 2, the unloading assembly 3, the second unwinding assembly 4, the traction assembly 6, the rolling and cutting assembly 7 and the conveying assembly 8 are arranged in sequence along the moving direction of the first packaging cloth.

[0109] In this embodiment, in a common hot packing machine, the first unwinding component 2, the unloading component 3, the second unwinding component 4, the traction component 6, and the rolling and cutting component 7 are arranged in sequence. Although the conveying component 8 and the winding component 9 are arranged at different positions in space, they are both in the terminal process in terms of logical control.

[0110] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
