[0051] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0052] In order to solve the problem in the prior art that the unloading speed of the powder pump unloading system is slow and that powder will remain in the powder pump vibration bin after the unloading operation is completed, the utility model provides a powder injection telescopic component, a powder pump device and a powder pump unloading system, wherein, Figures 14 to 17 As shown, the powder pump device includes a powder injection telescopic component 1 and a storage material discharge component 2, wherein the powder injection telescopic component 1 is the powder injection telescopic component described above and below; the storage material discharge component 2 is arranged on the shell 10 of the powder injection telescopic component 1, and the storage material discharge component 2 has a discharge port 200, and the discharge port 200 is connected to the discharge port 113 of the powder injection telescopic component 1; the powder pump unloading system includes a powder pump device, and the powder pump device is the powder pump device described above and below.

[0053] It should be noted that if Figures 14 to 17 As shown, the material storage and discharge assembly 2 includes a material storage bin 201, and a discharge port 200 is provided at the bottom of the material storage bin 201. The discharge port 200 of the material storage bin 201 is connected to the feed port 121 of the powder injection telescopic assembly 1 on the powder oscillation injection bottom plate. The top of the storage bin 201 is a loading port, and a detachable powder pump cover 202 is provided on the loading port at the top of the storage bin 201. A stirring screw shaft 203 is fixedly installed on the powder pump cover 202 through a bearing. The upper end of the stirring screw shaft 203 extends to the upper part of the powder pump cover 202, and is installed with a fork 204 that is detachably connected to other power units. The lower end of the stirring screw shaft 203 is located below the powder pump cover 202. When the powder pump cover 202 is buckled onto the storage bin 201, the lower end of the stirring screw shaft 203 is located in the storage bin 201, and is rotated after the other power units are connected to the fork 204, so that the powder discharge of the powder pump cover 202 is uniform and smooth.

[0054] In order to ensure the convenience of assembly between the material storage and discharge assembly 2 and other components, two rows of mutually parallel receiving slide blocks 205 are arranged on the material storage bin 201 or the powder pump cover 202 .

[0055] like Figures 1 to 13 As shown, the powder injection telescopic assembly includes a shell 10 and a powder pump vibrating silo 20, wherein the shell 10 has a accommodating chamber 100 and a feed port 121 and a discharge port 113 connected to the accommodating chamber 100, a portion of the accommodating chamber 100 forms a feed passage, and the two ends of the feed passage are respectively connected to the feed port 121 and the discharge port 113; the powder pump vibrating silo 20 is movably arranged in the accommodating chamber 100, and the powder pump vibrating silo 20 has a feeding position in which it moves into the feed passage and rotates a first preset angle along a first direction so that the silo inlet 211 of the powder pump vibrating silo 20 faces the feed port 121, and the powder pump vibrating silo 20 has a feeding position in which it exits the feed passage and rotates a second preset angle along a second direction so that the silo inlet 211 of the powder pump vibrating silo 20 faces downward and pours out the residual powder, and the second direction is opposite to the first direction.

[0056] By movably arranging the powder pump vibrating silo 20 in the accommodating chamber 100, the powder pump vibrating silo 20 has the function of moving into the material transfer channel and rotating a first preset angle along the first direction, so that the inlet 211 of the powder pump vibrating silo 20 is facing the unloading position of the material inlet 121, ensuring the reliability of the vibration unloading of the powder pump vibrating silo 20, thereby ensuring the unloading accuracy of the powder pump vibrating silo 20. Furthermore, since the movement of the powder pump vibrating silo 20 in the present application is relatively simple, unloading can be achieved by directly moving it into the material transfer channel and rotating a first preset angle along the first direction, which greatly improves the unloading speed of the powder pump vibrating silo 20. In addition, the powder pump vibrating silo 20 also has the function of exiting the material transfer channel and rotating a second preset angle along the second direction, so that the inlet 211 of the powder pump vibrating silo 20 is facing downward and pouring out the residual powder. Moreover, the second direction is opposite to the first direction, ensuring the convenience of rotation of the powder pump vibrating silo 20.

[0057] The powder pump vibrating silo 20 provided in the present application can not only move in a straight line but also rotate to achieve the purpose of pouring out the powder remaining in the powder pump vibrating silo 20 , thereby ensuring the cleanliness of the powder pump vibrating silo 20 .

[0058] It should be noted that, in the present application, the value of the first preset angle is equal to the value of the second preset angle. In this way, the powder pump vibration silo 20 only needs to rotate the same angle in the first direction and the second direction respectively, and the overall structural design is relatively simple and convenient.

[0059] like Figure 7As shown, the cavity wall of the accommodating cavity 100 has a first avoidance opening 111, and the powder injection telescopic assembly also includes a powder oscillation injection return box 30, which can be pulled out and arranged at the first avoidance opening 111 and is located below the powder pump vibration silo 20; wherein, the powder oscillation injection return box 30 has a columnar structure 31 protruding from the bottom surface of the box facing the side of the accommodating cavity 100, and the columnar structure 31 is provided with an avoidance hole 311, so that when the powder oscillation injection return box 30 is in a storage state, the avoidance hole 311 is connected with the discharge port 113, and the outer peripheral surface of the columnar structure 31 and the box wall of the powder oscillation injection return box 30 form a receiving area for collecting the powder poured out of the powder pump vibration silo 20. In this way, by setting the powder oscillation injection return box 30 to a pull-out structure, after the powder poured out of the powder pump vibration silo 20 is collected in the material receiving area, the powder oscillation injection return box 30 is pulled out and the powder collected therein is cleaned up, and then the cleaned powder oscillation injection return box 30 is pushed back into the accommodating chamber 100 through the first avoidance opening 111, and the operation is quick and convenient. In addition, the setting of the avoidance hole 311 ensures the reliability of the connection between the avoidance hole 311 and the discharge port 113, thereby ensuring the unloading reliability of the powder injection telescopic assembly 1, and the powder oscillation injection return box 30 is protruding from the bottom surface of the box toward the accommodating chamber 100, and the columnar structure 31 is provided with an avoidance hole 311. The setting of the columnar structure 31 prevents the powder collected in the material receiving area from entering the avoidance hole 311, thereby ensuring the reliability of the collection of powder in the material receiving area.

[0060] like Figure 6 and Figure 7 As shown, the powder oscillation injection and return box 30 includes a box body 32 and a pull-out structure 33 connected to each other, at least part of the box body 32 is located in the accommodating cavity 100, and the pull-out structure 33 is located outside the accommodating cavity 100. In this way, by setting the powder oscillation injection and return box 30 to include a connected box body 32 and a pull-out structure 33, the box body 32 can ensure the reliability of the powder oscillation injection and return box 30 to collect powder, and the pull-out structure 33 can ensure the convenience of the operator's pull-out operation.

[0061] It should be noted that in the present application, in order to ensure the compactness of the overall structure of the powder injection telescopic assembly 1, the extraction direction of the powder oscillation injection return box 30 is opposite to the direction in which the powder pump vibration silo 20 exits the material passage. Figure 7 , Fig. 9 As shown, the direction in which the powder oscillation injection return box 30 is withdrawn is toward the right in the figure, and the direction in which the powder pump vibration silo 20 exits the material transfer channel is toward the left in the figure.

[0062] Of course, in an embodiment not shown in the figure of the present application, the powder oscillation injection return box 30 is set to be relatively short, so as to avoid the material transfer channel between the feed port 121 of the powder injection telescopic assembly 1 and the discharge port 113 of the powder injection telescopic assembly 1.

[0063] It should be noted that in other embodiments, powder can also be collected by other forms, such as vacuum suction recovery. Of course, the vacuum suction equipment cannot work when the device is unloading normally. It only starts working when there is powder on the leakage net 212 in the silo body 21, so as to ensure the unloading accuracy during work.

[0064] like Figures 1 to 13 As shown, the powder injection telescopic assembly 1 also includes a first bearing seat 40, a spiral shaft 50 and a driving mechanism 60. The first bearing seat 40 is movably arranged in the accommodating chamber 100; the spiral shaft 50 includes a first shaft section 51 and a second shaft section 52 connected to each other. The first shaft section 51 passes through the bearing hole on the bearing in the first bearing seat 40 and is drivingly connected to the powder pump vibration silo 20. The outer peripheral surface of the second shaft section 52 has a first guide structure, and the top surface of the accommodating chamber 100 has a second guide structure for slidingly cooperating with the first guide structure; the driving mechanism 60 is arranged On the housing 10, the driving end of the driving mechanism 60 extends into the accommodating cavity 100 and is drivingly connected to the first bearing seat 40 to drive the first bearing seat 40 to move linearly; wherein, in the direction away from the first shaft section 51, the first guide structure includes a connected spiral section 5211 and a straight section 5212, and the second guide structure cooperates with the spiral section 5211 so that the spiral shaft 50 drives the powder pump vibrating silo 20 to rotate, and the second guide structure cooperates with the straight section 5212 so that the spiral shaft 50 drives the powder pump vibrating silo 20 to move linearly. In this way, by setting the first guide structure to include a connected spiral section 5211 and a straight section 5212, the linear movement reliability of the powder pump vibrating silo 20 is ensured, and the rotation reliability of the powder pump vibrating silo 20 is ensured.

[0065] It should be noted that, in the present application, the cross-sectional area of ​​the shaft section of the first shaft section 51 is smaller than the cross-sectional area of ​​the shaft section of the second shaft section 52. In this way, it is ensured that the second shaft section 52 can smoothly pass through the bearing hole of the first bearing seat 40 and be connected to the powder pump vibration silo 20, and a shoulder is formed at the connection between the first shaft section 51 and the second shaft section 52, and the first bearing seat 40 is driven to move linearly at the driving end of the driving mechanism 60. Since the second shaft section 52 is inserted into the bearing hole of the first bearing seat 40, the first bearing seat 40 pushes the screw shaft 50 to move through the shoulder.

[0066] like Figures 1 to 13As shown, considering that the hole length of the bearing hole of the first bearing seat 40 is relatively small and the first guide structure requires a longer path to enable the screw shaft 50 to drive the powder pump vibration silo 20 to produce linear movement and rotational movement, preferably, the axial length of the first shaft segment 51 is smaller than the axial length of the second shaft segment 52.

[0067] like Fig.14 As shown, the cavity wall of the accommodating cavity 100 has a second avoidance opening 112, and the second avoidance opening 112 is used to avoid the screw shaft 50. In this way, the movement reliability of the screw shaft 50 is ensured.

[0068] like Figures 1 to 13 As shown, the first guide structure is a first limiting groove 521 provided on the outer circumference of the spiral segment 5211, the cavity wall surface of the accommodating cavity 100 is protrudingly provided with an assembly structure 13, and the second guide structure is a first limiting protrusion 14 protrudingly provided on the assembly structure 13. In this way, the reliability of the sliding fit between the first limiting protrusion 14 and the first limiting groove 521 is ensured, and the first limiting protrusion 14 plays a guiding role in the movement of the spiral shaft 50.

[0069] It should be noted that, in an embodiment of the present application not shown in the figure, the first guide structure is a second limiting protrusion protruding on the outer peripheral surface of the spiral segment 5211, the cavity wall surface of the accommodating cavity 100 is protrudingly provided with an assembly structure 13, and the second guide structure is a second limiting groove provided on the assembly structure 13. In this way, the reliability of the sliding fit between the second limiting protrusion and the second limiting groove is ensured, and the second limiting protrusion plays a guiding role in the movement of the spiral shaft 50.

[0070] Specifically, if Figures 1 to 13 As shown, the first guide structure is a first limiting groove 521 provided on the outer circumference of the spiral segment 5211, the cavity wall surface of the accommodating cavity 100 is protrudingly provided with an assembly structure 13, and the second guide structure is a first limiting protrusion 14 protrudingly provided on the assembly structure 13, wherein the first limiting protrusion 14 is a rotating guide shaft rotatable relative to the assembly structure 13. In this way, by setting the first limiting protrusion 14 in a rotatable structure, it is ensured that the outer circumference of the first limiting protrusion 14 and the groove wall surface of the first limiting groove 521 are in rolling contact, which is conducive to reducing the friction between the two.

[0071] like Figures 1 to 13 As shown, the driving mechanism 60 includes a screw nut mechanism 61, a screw 611 of the screw nut mechanism 61 is rotatably disposed on the housing 10, and a nut 612 of the screw nut mechanism 61 is drivingly connected to the first bearing seat 40 in the accommodating cavity 100 through an intermediate transition piece 62. While ensuring the driving reliability of the driving mechanism 60, it can also ensure that the driving mechanism 60 does not occupy a large installation space, thereby ensuring the overall compactness of the structure of the powder injection telescopic assembly 1.

[0072] It should be noted that, in an embodiment of the present application which is not shown in the figure, the driving mechanism 60 includes a cylinder which is arranged on the housing 10 , and the telescopic end of the cylinder extends into the accommodating cavity 100 and is drivingly connected to the first bearing seat 40 .

[0073] It should be noted that in an embodiment of the present application not shown in the figure, the driving mechanism 60 includes a crank slider mechanism, which is arranged on the housing 10 and is drivingly connected to the first bearing seat 40 in the accommodating cavity 100 through an intermediate transition piece 62.

[0074] Of course, the driving mechanism 60 may also be other driving structure forms, which will not be described here.

[0075] like Figures 1 to 7 As shown, a evacuation channel 122 is provided on the wall surface of the accommodating chamber 100, and the evacuation channel 122 is extended along the moving direction of the powder pump vibration silo 20. In this way, the evacuation reliability of the evacuation channel 122 to the intermediate transition piece 62 is ensured.

[0076] It should be noted that in the specific embodiments provided in the present application, the above-mentioned cavity wall surface refers to the cavity top surface, and of course it can also be other cavity wall surfaces of the accommodating cavity 100.
