[0025] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0026] It should be noted that, in the embodiments of the present invention, the powder packaging bag is generally a snakeskin bag.

[0027] like Figure 1 and Figure 2As shown, an embodiment of the present invention provides a powder packaging machine. The powder packaging machine includes a support frame 1, a feeding assembly, a powder packaging bag support structure and a bag mouth clamping assembly. Among them, the feeding assembly is arranged on the support frame 1, the feeding assembly includes a feeding pipe 4 for conveying powder, and the powder packaging bag is sleeved on the outer periphery of the feeding pipe 4 so that the outlet of the feeding pipe 4 can convey powder to the powder packaging bag; the powder packaging bag support structure includes a supporting platform 2 for supporting the powder packaging bag, and the powder packaging bag support structure is arranged on the support frame 1 and is located below the feeding pipe 4; at least two bag mouth clamping assemblies are spaced apart on the peripheral side of the feeding pipe 4, and the bag mouth clamping assembly includes a telescopic structure and a floating structure connected to the telescopic structure, and the telescopic structure has a floating structure along the feeding pipe 4. The fixed end 41 and the telescopic end 42 are axially oppositely arranged, and the floating structure includes an elastic member 43 connected to the telescopic end 42 and an abutment member 44 connected to the elastic member 43. The abutment member 44 is floatably arranged relative to the telescopic end 42 along the radial direction of the feed pipe 4, and the abutment member 44 abuts against the outer wall of the feed pipe 4. The telescopic end 42 is movably arranged along the axis of the feed pipe 4 relative to the fixed end 41, so that the abutment member 44 has a first position abutting against the peripheral side surface of the powder packaging bag and clamping it on the outer periphery of the feed pipe 4, and a second position detached from the powder packaging bag and releasing it.

[0028] In the above technical solution, the bag opening of the powder packaging bag is sleeved on the outer periphery of the outlet of the feeding pipe 4. Since the telescopic end 42 is movably arranged along the axis of the feeding pipe 4 relative to the fixed end 41, the abutment 44 is floatingly arranged relative to the telescopic end 42, and under the action of the elastic member 43, the abutment 44 is always in abutment with the outer wall of the feeding pipe 4. In this way, in the process that the telescopic end 42 gradually moves away from the fixed end 41, the telescopic end 42 can drive the abutment 44 to gradually approach the bag opening of the powder packaging bag until it moves to the outer periphery of the powder packaging bag, and then the elastic member 43 is restored to its original position. Under the action of the restoring force, the elastic member 43 can push the abutment member 44 and abut the abutment member 44 against the outer periphery of the powder packaging bag, so that the abutment member 44 squeezes the surface of the powder packaging bag and fixes the powder packaging bag to the outer periphery of the feeding pipe 4, thereby solving the problem of separation between the outlet of the feeding pipe 4 and the bag opening, so as to avoid the problem of air and powder in the powder packaging bag diffusing outward from the bag opening and the feeding pipe 4, thereby reducing the dust in the workshop, avoiding dust flying in the air to endanger the health of operators, and also avoiding waste of raw materials and affecting the proportion quality of the finished product.

[0029] It should be noted that in the embodiment of the present invention, when the powder enters the powder packaging bag, the original air in the powder packaging bag will be squeezed into the feeding pipe 4 by the powder entering the bag, and then enters the storage box through the feeding pipe 4.

[0030] It should be noted that, in the embodiment of the present invention, generally, the staff sets the bag opening of the powder packaging bag on the outer periphery of the feeding pipe 4, and then fixes the packaging bag on the outer periphery of the feeding pipe 4 by using the bag opening clamping assembly.

[0031] Specifically, in the embodiment of the present invention, the telescopic structure includes an electric push rod and an extension rod connected to the electric push rod, the extension rod can extend the push rod, and the end of the extension rod away from the push rod forms a telescopic end 42, and the housing of the electric push rod forms a fixed end 41. The electric push rod is detachably connected to the extension rod, one end of the elastic member 43 is detachably connected to the outer surface of one side of the extension rod, the other end of the elastic member 43 is detachably connected to the abutment member 44, and the abutment member 44 is located on the lower outer surface of both sides of the conveying pipe 4.

[0032] In one embodiment, the telescopic structure may further include an electric cylinder and an extension rod connected to the piston rod of the electric cylinder. Alternatively, the extension rod may not be provided.

[0033] Specifically, in an embodiment of the present invention, the telescopic structure of at least two bag-mouth clamping assemblies is detachably mounted on the support frame 1, or the telescopic structure is detachably mounted on the feed pipe 4, as long as at least two bag-mouth clamping assemblies are arranged on the periphery of the feed pipe 4.

[0034] Specifically, Figure 1 As shown, in the embodiment of the present invention, two sides of the support frame 1 are detachably connected with support legs 13 to increase the stability of the support frame 1.

[0035] like Figure 2 As shown, in an embodiment of the present invention, a portion of the outer wall of the feed pipe 4 is recessed toward the side where the axis of the feed pipe 4 is located to form an inwardly recessed concave portion, and the abutment member includes an arc-shaped extrusion plate protruding toward the feed pipe 4, and the arc-shaped extrusion plate can cooperate with the concave portion.

[0036] In the above technical solution, since the powder packaging bag has a certain thickness, the powder packaging bag can be fixed at the position where the concave portion of the feeding tube 4 is located. In this way, when the telescopic end 42 gradually moves away from the fixed end 41, that is, when the telescopic end 42 drives the arc-shaped extrusion plate to gradually approach the bag opening of the powder packaging bag, the inwardly concave portion of the feeding tube 4 can Figure 2The lower end of the arc-shaped extrusion plate in the bag is avoided so that the lower end of the arc-shaped extrusion plate can be smoothly located at the periphery of the bag opening of the powder packaging bag until the arc-shaped extrusion plate moves to a position that cooperates with the recessed portion; then, under the action of the restoring force of the elastic member 43, the abutment member 44 can abut against the periphery of the powder packaging bag, so that the abutment member 44 squeezes the surface of the powder packaging bag and fixes the powder packaging bag to the periphery of the feeding pipe 4, thereby solving the problem of separation between the outlet of the feeding pipe 4 and the bag opening, and further avoiding the problem of air and powder in the powder packaging bag diffusing outward from between the bag opening and the feeding pipe 4.

[0037] It should be noted that if Figure 2 As shown, in the embodiment of the present invention, part of the outer wall of the feed pipe 4 is recessed toward the side where the axis of the feed pipe 4 is located to form an inwardly recessed portion, which means that the outer diameter of the recessed portion of the feed pipe 4 is smaller than the outer diameters of the two ends of the feed pipe 4.

[0038] It should be noted that if Figure 2 As shown in the embodiment of the present invention, the bottom wall of the concave portion is in the shape of an arc extending along the axial direction of the feeding pipe 4, so that when the powder packaging bag is filled with powder and the filling is completed, the telescopic end can drive the arc-shaped extrusion plate to Figure 2 The upper part of the middle part moves more smoothly, that is, the arc extrusion plate moves more smoothly in the direction away from the powder packaging bag.

[0039] It should be noted that in the embodiment of the present invention, since the abutment 44 can float along the radial direction of the feed tube 4 and the thickness of the powder packaging bag is relatively thin, the recess may not be provided. When the abutment 44 moves toward the powder packaging bag, if it encounters an obstacle at the edge of the bag opening, the abutment 44 can float along the radial direction of the feed tube 4 away from the feed tube 4 to avoid the edge of the bag opening until it moves to the outer periphery of the powder packaging bag, and the restoring force of the elastic member will press the powder packaging bag against the outer periphery of the feed tube 4.

[0040] like Figure 2 As shown, in the embodiment of the present invention, a clamping groove 492 is provided on the bottom wall of the recessed portion. When the abutting member 44 is in the first position, the clamping groove 492 cooperates with the abutting member 44 to press the powder packaging bag tightly into the clamping groove 492 .

[0041] Through the above arrangement, the powder packaging bag can be more stably fixed on the outer periphery of the feeding pipe 4, thereby preventing the powder packaging bag from falling off from between the feeding pipe 4 and the arc extrusion plate, and further avoiding the problem of separation between the outlet of the feeding pipe 4 and the bag opening, so as to avoid the problem of air and powder in the powder packaging bag diffusing outward from between the bag opening and the feeding pipe 4.

[0042] Specifically, Figure 4As shown, in the embodiment of the present invention, since the abutment member 44 is always in abutment with the outer wall of the feed pipe 4, the abutment member 44 also includes a wear-resistant plate 442 detachably connected to the side of the arc extrusion plate facing the feed pipe.

[0043] Specifically, Figure 4 As shown, in the embodiment of the present invention, the abutment 44 also includes an extrusion-fit soft block 441 detachably connected to the side of the wear-resistant plate 442 facing the feed pipe 4, so that the extrusion-fit soft block 441 can play a buffering role to prevent the abutment 44 from damaging the powder packaging bag.

[0044] Specifically, Figure 4 As shown, in the embodiment of the present invention, a side of the feeding pipe 4 facing the abutment member 44 is also provided with an extrusion-fit soft block 441, so that both sides of the powder packaging bag can be provided with an extrusion-fit soft block 441 to prevent the powder packaging bag from being worn.

[0045] like Figure 2 As shown, in the embodiment of the present invention, the powder packaging machine further includes a dust recovery structure, which includes an exhaust fan 45, a dust recovery pipe 46 and a recovery guide pipe 47. The exhaust fan 45 is arranged in the feed pipe 4; the dust recovery pipe 46 is located in the feed pipe 4, and the dust recovery pipe 46 is arranged along the axis of the feed pipe 4, and the air inlet end 461 of the dust recovery pipe 46 is in the same direction as the outlet of the feed pipe 4; the recovery guide pipe 47 is penetrated in the feed pipe 4 and is arranged at an angle with the dust recovery pipe 46, and the air outlet of the dust recovery pipe 46 is connected with the inlet end of the recovery guide pipe 47 through the exhaust fan 45, and the air outlet end of the recovery guide pipe 47 extends out of the feed pipe 4.

[0046] Through the above-mentioned arrangement, the dust recovery pipe 46, the exhaust fan 45 and the recovery guide pipe 47 are used to absorb the powder floating in the bag opening and the conveying pipe 4, so as to reduce the possibility of the powder and air overflowing from the gap between the bag opening and the conveying pipe 4, and solve the problem of the powder diffusion caused by the air flow when the powder is filled, so as to achieve the effect of absorbing the powder in the internal air; and the recovery guide pipe 47 can recover the above-mentioned powder and air through a separate pipeline, so as to avoid the dust overflowing from the bag opening from the conveying pipe 4 to enter the storage box, thereby avoiding affecting the conveying of the conveying pipe 4.

[0047] Furthermore, the dust recovery structure cooperates with the bag opening clamping assembly to effectively prevent dust from overflowing from the gap between the bag opening and the feed pipe 4 .

[0048] Specifically, Figure 4As shown, in an embodiment of the present invention, the exhaust fan 45 is detachably mounted on the upper inner surface of the conveying pipe 4, and the air outlet end of the exhaust fan 45 is detachably connected to the recovery guide pipe 47, the dust recovery pipe 46 is detachably connected to the air inlet end of the exhaust fan 45, and one end of the recovery guide pipe 47 extends to the outer surface of the conveying pipe 4.

[0049] Specifically, Figure 1 As shown, in an embodiment of the present invention, a one-way deflector 14 is detachably connected to the top outer surface of the support frame 1, and the one-way deflector 14 is used to connect the storage box and the feed pipe 4, and enable the powder to flow in one direction, thereby preventing the dust overflowing from the bag mouth from entering the storage box from the feed pipe 4, thereby avoiding affecting the feed of the feed pipe 4.

[0050] Preferably, in the embodiment of the present invention, the recovery guide tube 47 is connected to the inlet of the one-way guide 14, so that the powder recovered by the recovery guide tube 47 can flow into the feed pipe 4 through the one-way guide 14 and enter the powder packaging bag together with the new material.

[0051] Preferably, in an embodiment of the present invention, a plurality of through holes are provided at the end of the dust recovery pipe 46 , the plurality of through holes form the air inlet end 461 , and the exhaust fan 45 can guide some powder material falling on the inner bottom of the dust recovery pipe 46 upward.

[0052] like Figure 2 and Figure 3 As shown, in an embodiment of the present invention, the dust recovery structure also includes a plurality of main suction pipes 463 connected to the dust recovery pipe 46, and the plurality of main suction pipes 463 are arranged at intervals along the axial direction of the dust recovery pipe 46, and there is an angle between the axis of the main suction pipe 463 and the axis of the dust recovery pipe 46.

[0053] Through the above-mentioned arrangement, the range of powder absorption by the dust recovery structure can be effectively increased, and the multiple main suction pipes 463 can also absorb the powder attached to the inner wall of the conveying pipe 4, thereby improving the recovery effect and efficiency of the powder, and then reducing the possibility of powder and air overflowing from the gap between the bag mouth and the conveying pipe 4, solving the problem of powder diffusion caused by the flow of air when the powder is filled, so as to achieve the effect of absorbing the powder in the internal air.

[0054] Specifically, Figure 3As shown, in an embodiment of the present invention, a lap joint structure 462 is detachably connected to the outer surface of the dust recovery pipe 46, and a main suction pipe 463 is detachably connected to the outer surface of one side of the lap joint structure 462. The lap joint structure 462 is used to fix the main suction pipe 463 on the dust recovery pipe 46, and the main suction pipe 463 is connected to the dust recovery pipe 46 through the interior of the lap joint structure 462. In this way, the number of main suction pipes 463 can be set according to the dust collection requirements and the length of the feed pipe 4.

[0055] Specifically, Figure 3 As shown, in the embodiment of the present invention, the two main suction pipes 463 are connected to the dust recovery pipe 46 through the interior of an overlapping structure 462.

[0056] like Figure 3 As shown, in an embodiment of the present invention, the dust recovery structure also includes a plurality of auxiliary suction ducts 464 arranged on at least one side of the main suction duct 463 and connected to the main suction duct 463, and the plurality of auxiliary suction ducts 464 are arranged at intervals along the axial direction of the main suction duct 463, and the axis of the main suction duct 463 is arranged at an angle to the axis of the auxiliary suction duct 464.

[0057] Through the above-mentioned arrangement, the range and angle of powder absorption of the dust recovery structure can be effectively increased, and the multiple auxiliary suction pipes 464 can also absorb the powder attached to the inner wall of the feed pipe 4, thereby improving the recovery effect and efficiency of the powder, and then reducing the possibility of powder and air overflowing from the gap between the bag mouth and the feed pipe 4, solving the problem of powder diffusion caused by the flow of air when the powder is filled, so as to achieve the effect of absorbing the powder in the internal air.

[0058] Preferably, if Figure 3 As shown, in the embodiment of the present invention, a plurality of auxiliary air suction pipes 464 are detachably connected to the upper and lower outer surfaces of the main air suction pipe 463 .

[0059] like Figure 1 As shown, in the embodiment of the present invention, the powder packaging machine further includes a lifting structure and a telescopic hose 15. The lifting structure includes a lifting body 11 disposed on the support frame 1 and a lifting output end movably disposed along the axis of the feed pipe 4 relative to the lifting body 11; the telescopic hose 15 is used to pass the powder, one end of the telescopic hose 15 is fixed on the support frame 1, the inlet of the feed pipe 4 is connected to the other end of the telescopic hose 15, and the lifting output end is connected to the feed pipe 4 to drive the feed pipe 4 to move along its own axis relative to the support frame 1.

[0060] Through the above arrangement, the lifting structure can be used to stretch the telescopic hose 15, and the feeding pipe 4 connected to the lifting output end can be lowered, so that the air in the powder packaging bag can be squeezed out. In this way, when the powder is filled, it can be avoided that air flows out from the powder packaging bag and causes dust to float, thereby avoiding the problem that the powder flows around in the feeding pipe 4 and the powder is easily diffused from the gap between the feeding pipe 4 and the bag opening of the powder packaging bag.

[0061] Preferably, if Figure 3 As shown, in the embodiment of the present invention, one end of the telescopic hose 15 away from the material conveying pipe 4 is connected to the outlet of the one-way flow guide 14 .

The lifting output end is detachably connected to the feed pipe 4 through the lifting plate 12, so that there can be a gap between the feed pipe 4 and the lifting body 11, thereby avoiding the structure being too tight and affecting the movement of the lifting output end.

[0063] Preferably, in an embodiment of the present invention, the lifting structure is a linear motor or an electric cylinder.

[0064] like Figure 1 and Figure 6 As shown, in the embodiment of the present invention, the powder packaging machine further includes a material guiding structure 3, a vibration motor 32 and a vibration member 33. The material guiding structure 3 is arranged on the support frame 1, and the material guiding structure 3 defines a material guiding cavity and a feed port 31 and a discharge port 35 connected to the material guiding cavity. The material guiding structure 3 is located above the material conveying pipe 4, and the inlet of the material conveying pipe 4 is connected to the discharge port 35; the vibration motor 32 is arranged in the material guiding cavity; the vibration member 33 is arranged obliquely in the material guiding cavity, the first end of the vibration member 33 is higher than the second end of the vibration member 33, and the discharge port 35 is located on the side where the second end is located, and the vibration member 33 is drivingly connected to the output shaft of the vibration motor 32, so that the vibration member 33 can reciprocate in the material guiding cavity.

[0065] Through the above arrangement, the powder material entering through the feed port 31 can slide to the discharge port 35 under the action of the vibrating member 33 , thereby guiding the powder material to the feed pipe 4 to achieve the function of guiding the material.

[0066] Preferably, in the embodiment of the present invention, the vibrating member 33 is made of an elastic sheet, so that it is convenient for the vibration motor 32 to drive the vibrating member 33 to vibrate, so as to improve the vibration effect of the vibrating member 33 .

[0067] It should be noted that in the embodiment of the present invention, the structure of the vibration motor 32 is prior art and will not be described in detail herein.

[0068] Preferably, in the embodiment of the present invention, the vibration motor 32 and the vibration member 33 are both detachably connected to the material guiding structure 3 .

[0070] Through the above arrangement, the plurality of swing plates 34 can hinder the powder entering from the feed port 31 and slow down the sliding speed of the powder in the material guide cavity to achieve uniform discharge, thereby avoiding the problem of blockage of the discharge port 35 due to a large amount of powder entering the feed port 31 and causing the discharge port 35 to be blocked in time.

[0071] like Figure 1 and Figure 5 As shown, in the embodiment of the present invention, the powder packaging bag support structure further includes two mechanical arms 24 and two clamping members 25. The two mechanical arms 24 are located on opposite sides of the support platform 2, and the mechanical arms 24 are swingably arranged relative to the support platform 2; the two clamping members 25 are respectively connected to the two mechanical arms 24, and the two clamping members 25 are used to clamp the powder packaging bag to ensure that the powder packaging bag can stand upright.

[0072] Through the above arrangement, the powder packaging bag is placed on the supporting platform 2. As the powder inside the bag is filled, the mechanical arm 24 can be controlled to swing, and the surfaces of the two clamping members 25 can be overlapped on the surface of the powder packaging bag. When the height of the powder packaging bag is relatively high, the powder packaging bag can be stably supported. When filling the powder, the powder packaging bag support structure can be used instead of manual support for the powder packaging bag, thereby avoiding the problem of laborious and labor-intensive work.

[0073] It should be noted that, in the embodiment of the present invention, the robotic arm 24 includes multiple swing arms and multiple rotating shafts 23, a rotating shaft 23 is provided between two adjacent swing arms, and the first swing arm is pivotally connected to the support platform through the rotating shaft 23, and the last swing arm is pivotally connected to the clamping member 25 through the rotating shaft 23 to achieve flexible swinging of the robotic arm 24, and the structure of the robotic arm 24 is prior art and will not be repeated here.

[0074] Specifically, Figure 5 As shown, in the embodiment of the present invention, a trapezoidal extrusion block 26 is detachably connected to the outer surface of one side of the clamping member 25, so that the friction force of the trapezoidal extrusion block 26 acting on the surface of the powder packaging bag can support the powder packaging bag more stably.

[0075] like Figure 5As shown, in the embodiment of the present invention, the support platform 2 includes a support body and a buffer layer 21 disposed on the support body. The buffer layer 21 is located on the side of the support body facing the feed pipe 4, and the buffer layer 21 is made of a flexible material.

[0076] Through the above arrangement, the buffer layer 21 can buffer the weight of the powder packaging bag, thereby preventing the powder falling from a high place from directly hitting the supporting body and causing the powder packaging bag to become unstable. In this way, the powder packaging bag can be stably supported.

[0077] Specifically, Figure 5 As shown, in the embodiment of the present invention, a wear-resistant protective layer 22 is detachably connected to the top outer surface of the buffer layer 21. In this way, the friction between the powder packaging bag and the supporting platform 2 can be increased, so that the powder packaging bag can be stably supported.

[0078] like Figure 2 As shown, in the embodiment of the present invention, the powder packaging machine further includes a material mixing structure located at the inlet of the feeding pipe 4, and the material mixing structure includes two material blocking members 48 and two elastic structures. The two material blocking members 48 are pivotally connected to the inner wall of the feeding pipe 4; the two elastic structures are respectively arranged corresponding to the two material blocking members 48, one end of the elastic structure is connected to the material blocking member 48, and the other end of the elastic structure is connected to the inner wall of the feeding pipe 4. Under the impact of the powder, the material blocking member 48 can be swingably arranged.

[0079] Through the above arrangement, under the action of the gravity of the powder, the blocking member 48 can be opened to allow the powder to enter the interior of the feed pipe 4. In this way, multiple blocking members 48 can prevent excessive powder from entering the feed pipe 4 to achieve uniform feeding, thereby avoiding the problem of clogging the feed pipe 4 due to excessive powder entering.

[0080] Furthermore, as the powder in the bag gradually accumulates, when the powder packaging bag is almost full, the filling of the powder can be stopped, and the material blocking member 48 is reset to close the inlet of the material delivery pipe 4.

[0081] The following is a detailed description of the working principle of the lifting dust removal and powder recovery packaging machine.

[0082] like Figures 1 to 6As shown, the powder packaging bag is placed on the outer surface of the wear-resistant protective layer 22, the rotating shaft 23 is cooperated to swing the multiple swing arms, the surface of the clamping member 25 is overlapped on the surface of the powder packaging bag, the friction force of the trapezoidal extrusion block 26 on the surface of the powder packaging bag is cooperated, and the weight of the powder packaging bag is buffered by the buffer layer 21, so that the powder packaging bag can be stably placed on the supporting platform 2, the bag mouth of the powder packaging bag is clamped on the outer surface of the bottom end of the feeding pipe 4, the telescopic end 42 is vertically away from the fixed end 41, the elastic member 43 is cooperated to push the abutment 44, so that the abutment 44 squeezes and fixes the surface of the bag mouth, and the lifting structure is used to lower the lifting plate 12 to stretch the telescopic soft Tube 15 is used to squeeze out the air inside the bag, and the powder is infused in cooperation with the material guiding structure 3 and the one-way deflector 14. The blocking member 48 is squeezed by the weight of the powder to open it, and the powder is poured into the powder packaging bag in cooperation with the feeding pipe 4. As the bag is gradually piled up and the powder packaging bag is almost full, the filling of the material is stopped, the blocking member 48 is reset to close the top of the feeding pipe 4, and the exhaust fan 45 sucks air from the dust recovery pipe 46, and cooperates with the main suction pipe 463 and multiple auxiliary suction pipes 464 on the outer surface of the overlapping structure 462 to absorb the powder in the outside air, absorb the powder scattered in the internal space of the feeding pipe 4, and guide it to the inlet of the one-way deflector 14 through the recovery guide pipe 47.

[0083] From the above description, it can be seen that the above-mentioned embodiment of the present invention achieves the following technical effects: the bag opening of the powder packaging bag is sleeved on the outer periphery of the outlet of the feeding pipe, and since the telescopic end is movably arranged along the axis of the feeding pipe relative to the fixed end, the abutment is floatingly arranged relative to the telescopic end, and under the action of the elastic member, the abutment is always in abutment with the outer wall of the feeding pipe, so that in the process that the telescopic end gradually moves away from the fixed end, the telescopic end can drive the abutment to gradually approach the bag opening of the powder packaging bag until it moves to the outer periphery of the powder packaging bag, and then Under the action of the restoring force of the elastic member, the elastic member can push the abutment member and abut the abutment member against the outer periphery of the powder packaging bag, so that the abutment member squeezes the surface of the powder packaging bag and fixes the powder packaging bag to the outer periphery of the feeding pipe, thereby solving the problem of separation between the outlet of the feeding pipe and the bag opening, so as to avoid the problem of air and powder in the powder packaging bag diffusing outward from between the bag opening and the feeding pipe, thereby reducing the dust in the workshop, avoiding dust flying in the air to endanger the health of operators, and also avoiding waste of raw materials and affecting the proportion quality of the finished product.

[0084] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
