Description

Technical Field

[0001] The invention relates to the technical field of powder processing and weighing, in particular to a heating tank powder feeding and weighing device. Background Art

[0002] The heating tank can heat and melt the raw materials in powder form. The feed port of the heating tank is generally connected to the discharge port of the weighing box. The weighing box is used to control the ratio of the powder to ensure that the temperature distribution of the powder is consistent after entering the heating tank, which helps to balance the heat absorption.

[0003] When the powder material is damp due to the environment, part of the powder material tends to adhere to the inner wall of the weighing box during the transfer from the weighing box to the heating tank. The agglomerated powder material tends to block the discharge port, making it impossible for the weighed powder material in the weighing box to completely enter the heating tank, affecting the processing quality of the powder material and the next normal weighing operation of the weighing box. Prior art patent No. CN113932895A discloses a powder weighing device, which can scrape off the raw materials adhered to the inner wall of the barrel through a rubber scraper, loosen the powder material as it falls from the barrel, prevent the powder material from caking or adhering to the inner wall of the barrel and affecting the falling of the powder material, and make the powder material propulsion and stirring more uniform.

[0004] However, the existing technology still has the following defects: the traditional stirring method (vertical rotation and horizontal rotation) has a poor effect on the exchange of powder position, the stirring rod is difficult to contact all the agglomerated powder, and it is difficult to break up the agglomerated powder by relying solely on the rotation of the stirring rod. At the same time, the setting of the rubber scraper increases the frequency of subsequent maintenance, and the use effect is poor. Summary of the Invention

[0005] In view of the problems in the existing technology that the transmission stirring method has poor efficiency in turning the powder and it is difficult to effectively break up the agglomerated powder, a heating tank powder feeding weighing device is proposed.

[0006] Its purpose is to generate vibration on the weighing box when the sleeve moves up and down intermittently, and at the same time increase the turning range of the stirring element. The crushing mechanism performs intermittent compression as it rotates with the stirring element, and squeezes and crushes the intercepted agglomerated powder.

[0007] The technical solution of the present invention is a heating tank powder feeding weighing device, comprising a weighing frame and a weighing box mounted and connected thereto, wherein a sleeve is vertically provided at the axis center of the weighing box, and both ends of the sleeve are elastically connected to the weighing box via a reset member, and a plurality of stirring members are rotatably provided on the outer wall of the lower end of the sleeve, and the stirring members are arranged near the discharge port of the weighing box, and a crushing mechanism is provided on the stirring members. When the stirring members rotate, the powder is turned over and the agglomerated powder is transported to the crushing mechanism, and the crushing mechanism intercepts the agglomerated powder and squeezes and crushes it; A drive shaft is provided for rotation in the sleeve, the drive shaft is driven by a power unit, the drive shaft is connected to the stirring element via a gear set, and a lifting assembly is connected between the drive shaft and the sleeve. When the drive shaft rotates, the sleeve is driven to move up and down through the lifting assembly, and the sleeve vibrates the weighing box and increases the stirring range of the stirring element. The crushing mechanism includes a plurality of fixed plates arranged on the stirring member, and an extrusion plate is provided between two adjacent fixed plates. The crushing mechanism also includes a transmission member, and the transmission member is used to drive the extrusion plate to move horizontally.

[0008] By adopting the above technical solution, before the weighing box conveys the powder to the heating tank, the power unit drives the driving shaft to rotate, and the driving shaft drives the stirring piece to rotate through the gear set, and the stirring piece turns the powder to loosen it. The driving shaft drives the sleeve to move up and down intermittently through the lifting assembly. The sleeve vibrates the weighing box during movement, and the powder adhered to the inner wall of the weighing box can be vibrated and separated. At the same time, the stirring piece rises and falls synchronously with the sleeve during rotation, thereby increasing the turning range of the powder. When turning the powder, the stirring piece can transport the agglomerated powder to one side of the crushing mechanism, and two adjacent fixed plates cooperate to intercept the agglomerated powder. The extrusion plate is driven to move intermittently by the transmission member, and the extrusion plate cooperates with the adjacent fixed plate to extrude and crush the intercepted agglomerated powder.

[0009] Furthermore, the reset member includes a connecting piece fixedly sleeved on the outer wall of the sleeve, the connecting piece is slidably connected to a limiting sleeve, an elastic member is commonly connected between the connecting piece and the limiting sleeve, the upper side of the limiting sleeve is connected and fixed to the top of the weighing box, and the lower side of the limiting sleeve is connected and fixed to the discharge port of the weighing box.

[0010] By adopting the above technical solution, the connecting piece and the limit sleeve slide together to limit the vertical sliding of the sleeve. When the sleeve is driven up by the lifting assembly, the elastic piece is compressed and accumulates force, and then the elastic piece releases the elastic force to drive the sleeve to descend rapidly. The connecting piece descends and hits the limit sleeve, thereby generating vibration on the weighing box, and the powder adhering to the inner wall of the weighing box can be vibrated and separated.

[0011] Furthermore, the stirring member includes a rotating sleeve rotatably connected to the outer wall of the sleeve, and a plurality of stirring blades are fixedly connected to the rotating sleeve at equal intervals in a ring shape, and the stirring blades are arranged at an angle.

[0012] With the above technical solution, when the driving shaft drives the stirring member to rotate through the gear set, the inclined surface of the stirring blade flips the powder upward, so that the powder in the weighing box exchanges positions and loosens the powder.

[0013] Furthermore, the drive shaft includes a rotating shaft 1 rotatably connected to the sleeve, the rotating shaft 1 and the rotating sleeve are connected through a gear set, the upper end of the rotating shaft 1 is slidingly sleeved with a rotating shaft 2, the upper end of the rotating shaft 2 passes through the sleeve and the weighing box and is connected to the output end of the power unit, and the power unit is a motor.

[0014] By adopting the above technical solution, the motor drives the second and first shafts to rotate synchronously. Through the sliding cooperation between the first and second shafts, when the first shaft follows the sleeve to move up and down, the second shaft always maintains a transmission connection with the first shaft.

[0015] Furthermore, the lifting assembly includes a U-shaped seat fixedly sleeved on the two outer walls of the rotating shaft, and both ends of the U-shaped seat are rotatably connected to guide wheels. The lifting assembly also includes a plurality of wedge blocks evenly distributed on the outer wall of the upper end of the sleeve.

[0016] Using the above technical solution, the inclined surface of the wedge block is set downward. When the second rotating shaft rotates, it drives the U-shaped seat and the guide wheel to rotate. When the guide wheel contacts the inclined surface of the wedge block, it drives the sleeve to rise. At this time, the elastic piece is compressed and accumulates force, and the rotating shaft one contracts toward the rotating shaft two. When the guide wheel leaves the wedge block, the elastic piece resets and drives the sleeve to descend rapidly, and generates vibration for the measuring box.

[0017] Furthermore, the plurality of fixed plates are arranged in a plurality of groups, the fixed plates in each group are distributed at equal intervals, and the fixed plates in each group are fixedly connected to the upper end of the stirring blade.

[0018] By adopting the above technical solution, when the stirring blade rotates, the inclined surface drives the powder to flip upward, and the powder passes through the gap between the two adjacent fixed plates, while the agglomerated powder can be intercepted by the gap between the two adjacent fixed plates, and then the extrusion plate can move to extrude and crush the intercepted agglomerated powder.

[0019] Furthermore, the transmission member includes a fixed disk arranged in the rotating sleeve, the fixed disk is fixedly sleeved on the outer wall of the sleeve, a driving groove is opened on the fixed disk, a driving rod is slidably connected to the driving groove, a connecting rod is fixedly connected to the driving rod, the connecting rod passes through the rotating sleeve and is slidably connected to the stirring blade, and the connecting rod is fixedly connected to the corresponding extrusion plate; The driving groove includes two symmetrically distributed arc grooves, and a V-shaped groove is connected between the two arc grooves.

[0020] By adopting the above technical solution, the stirring blade drives the connecting rod to rotate synchronously. When the driving rod moves in the arc groove of the driving groove, the connecting rod and the stirring blade remain relatively stationary. When the driving rod slides in the V-shaped groove, it can drive the connecting rod to perform a horizontal reciprocating motion, so that the extrusion plate moves toward the side of the adjacent and distant fixed plate, and extrude and crush the agglomerated powder intercepted between the two adjacent fixed plates.

[0021] Furthermore, a plurality of intercepting plates are evenly distributed vertically between two adjacent fixed plates, and a through hole is provided at the position of the extrusion plate corresponding to the intercepting plate. The intercepting plate is composed of a straight plate portion and a triangular plate portion, and a cutting edge is provided on the side of the intercepting plate facing the stirring blade.

[0022] By adopting the above technical solution, the interception plate and the two fixed plates can cooperate to intercept smaller agglomerated powder materials, thereby improving the interception rate. The agglomerated powder materials can be cut by the setting of the cutting blade during the process of being squeezed and crushed, thereby improving the crushing effect.

[0023] Furthermore, the fixing plate and the extrusion plate are both provided with a concave groove on one side facing the stirring blade, and the concave groove is provided with an arc-shaped blade.

[0024] The above technical solution improves the interception effect of agglomerated powder by providing a concave groove, preventing the fine powder from moving on the stirring blade and causing the agglomerated powder to break away from the fixed plate. At the same time, the provision of the arc-shaped blade can initially crush agglomerated powder with less agglomeration force, thereby reducing the subsequent crushing pressure. The remaining structure is the same as that of the embodiment.

[0025] Compared with the prior art, the present invention has the following beneficial effects: 1. The intermittent up and down movement of the sleeve makes the weighing box vibrate to prevent the powder from adhering to the inner wall of the weighing box. The sleeve drives the stirring element to move up and down synchronously, thereby increasing the stirring range of the stirring element on the powder, so that it can come into contact with the agglomerated powder as much as possible. At the same time, the extrusion plate cooperates with the fixed plate in the intermittent horizontal movement to effectively extrude and crush the intercepted agglomerated powder, thereby preventing the agglomerated powder from clogging the discharge port of the weighing box.

[0026] 2. By setting the interception plate between two adjacent fixed plates, the smaller agglomerated powder can be intercepted, thereby improving the interception effect. At the same time, the setting of the interception plate enables the extrusion plate to pre-clamp the smaller agglomerated powder during the translation process to prevent it from escaping, and then extrude and split it in cooperation with the cutting edge of the interception plate, so that the agglomerated powder can be broken more finely.

[0027] 3. When the agglomerated powder enters the concave grooves of the fixed plate and the extrusion plate, the escape of the agglomerated powder can be effectively prevented. At the same time, the setting of the arc-shaped blade can preliminarily crush the agglomerated powder with less agglomeration force, thereby reducing the subsequent crushing pressure.

At the same time, the stirring member 5 rises and falls synchronously with the sleeve 3 during rotation, thereby increasing the turning range of the powder. When turning the powder, the stirring member 5 can transport the agglomerated powder to one side of the crushing mechanism, and the two adjacent fixed plates 7 cooperate to intercept the agglomerated powder, and the extrusion plate 8 is driven to move intermittently through the transmission member 9.

The upper limiting sleeve 42 is connected and fixed to the top of the weighing box 2, and the lower limiting sleeve 42 is connected and fixed to the discharge port of the weighing box 2.

[0035] Specifically, the connecting piece 41 and the limiting sleeve 42 slide together to limit the vertical sliding of the sleeve 3. When the sleeve 3 is driven up by the lifting assembly 11, the elastic member 43 is compressed and stores force, and then the elastic member 43 releases the elastic force to drive the sleeve 3 to descend rapidly. The connecting piece 41 descends and hits the limiting sleeve 42, thereby generating vibration for the weighing box 2, and the powder adhered to the inner wall of the weighing box 2 can be vibrated and separated.

[0036] In this technical solution, a plurality of protrusions are fixed on the outer periphery of the connecting piece 41, and a vertical sliding groove adapted to the protrusions is opened on the inner wall of the limiting sleeve 42. The elastic member 43 is preferably a spring, and the spring sleeve is arranged on the outside of the sleeve 3, and the two ends are respectively connected and fixed to the connecting piece 41 and the limiting sleeve 42.

[0037] Reference Figure 3 The stirring member 5 includes a rotating sleeve 51 rotatably connected to the outer wall of the sleeve 3, and a plurality of stirring blades 52 are fixedly connected to the rotating sleeve 51 in an annular shape and at equal intervals. The stirring blades 52 are arranged obliquely.

[0038] Specifically, when the driving shaft 6 drives the stirring member 5 to rotate through the gear set 10, the inclined surface of the stirring blade 52 flips the powder upward, so that the powder in the weighing box 2 is exchanged and the powder is loosened.

[0039] Reference Figure 1 、 Figure 5 The driving shaft 6 includes a rotating shaft 61 rotatably connected to the sleeve 3. The rotating shaft 61 and the rotating sleeve 51 are connected through a gear set 10. The upper end of the rotating shaft 61 is slidably sleeved with a rotating shaft 2 62. The upper end of the rotating shaft 2 62 passes through the sleeve 3 and the weighing box 2 and is connected to the output end of the power unit. The power unit is a motor.

[0040] Specifically, the motor drives the second rotating shaft 62 and the first rotating shaft 61 to rotate synchronously. Through the sliding cooperation between the first rotating shaft 61 and the second rotating shaft 62, when the first rotating shaft 61 follows the sleeve 3 to move up and down, the second rotating shaft 62 always maintains a transmission connection with the first rotating shaft 61.

[0041] Among them, the gear set 10 includes a face gear 1 fixedly sleeved on the outer wall of the rotating shaft 1 61 and a face gear 2 fixedly connected to the rotating sleeve 51. A plurality of gear shafts are meshed and connected between the face gear 1 and the face gear 2. The gear shafts are arranged horizontally through the sleeve 3 and are rotatably connected to the sleeve 3.

[0042] Reference Figure 6The rotating sleeve 51 is composed of two U-shaped sleeves, which are connected and fixed by bolts. The face gear 2 is composed of two sector gears and is fixed in the corresponding U-shaped sleeves. A rotation limit groove is provided at the upper and lower through holes of the U-shaped sleeve. A limit rotating ring is fixed at the position of the rotation limit groove on the outer wall of the sleeve 3. The rotation limit groove and the limit rotating ring cooperate to enable the rotating sleeve 51 to rotate on the outer wall of the sleeve 3. In addition, dust covers are snap-fitted on the upper and lower sides of the rotating sleeve 51. The dust cover is sleeved on the outer wall of the sleeve 3. The setting of the dust cover can prevent powder from entering the interior of the rotating sleeve 51, and the dust cover located on the upper side of the rotating sleeve 51 is truncated into a cone shape to prevent powder from accumulating on the dust cover.

[0043] Reference Figure 4 、 Figure 5 The lifting assembly 11 includes a U-shaped seat 111 fixedly sleeved on the outer wall of the second rotating shaft 62, and both ends of the U-shaped seat 111 are rotatably connected to guide wheels 112. The lifting assembly 11 also includes a plurality of wedge blocks 113 evenly distributed on the outer wall of the upper end of the sleeve 3.

[0044] Specifically, the inclined surface of the wedge block 113 is set to face downward. When the second rotating shaft 62 rotates, it drives the U-shaped seat 111 and the guide wheel 112 to rotate. When the guide wheel 112 contacts the inclined surface of the wedge block 113, it drives the sleeve 3 to rise. At this time, the elastic member 43 is compressed and stores force, and the rotating shaft 1 61 contracts into the rotating shaft 2 62. When the guide wheel 112 leaves the wedge block 113, the elastic member 43 resets and drives the sleeve 3 to descend rapidly, and generates vibration for the measuring box 2.

[0045] Reference Figure 3 The plurality of fixed plates 7 are arranged in a plurality of groups, each group of fixed plates 7 is distributed at equal intervals, and each group of fixed plates 7 is fixedly connected to the upper end of the stirring blade 52 .

[0046] Specifically, when the stirring blade 52 rotates, the inclined surface drives the powder to flip upward, and the powder passes through the gap between the two adjacent fixed plates 7, while the agglomerated powder can be intercepted by the gap between the two adjacent fixed plates 7, and then the extrusion plate 8 can move to extrude and crush the intercepted agglomerated powder.

[0047] Reference Figure 7 、 Figure 8 The transmission member 9 includes a fixed disk 91 arranged in the rotating sleeve 51, the fixed disk 91 is fixedly sleeved on the outer wall of the sleeve 3, and a driving groove 92 is opened on the fixed disk 91. A driving rod 93 is slidably connected to the driving groove 92, and a connecting rod 94 is fixedly connected to the driving rod 93. The connecting rod 94 passes through the rotating sleeve 51 and is slidably connected to the stirring blade 52, and the connecting rod 94 is fixedly connected to the corresponding extrusion plate 8; the driving groove 92 includes two symmetrically distributed arc grooves, and a V-shaped groove is connected between the two arc grooves.

[0048] Specifically, the stirring blade 52 drives the connecting rod 94 to rotate synchronously. When the driving rod 93 moves in the arc groove of the driving groove 92, the connecting rod 94 and the stirring blade 52 remain relatively stationary. When the driving rod 93 slides in the V-shaped groove, it can drive the connecting rod 94 to perform a horizontal reciprocating motion, so that the extrusion plate 8 moves toward the adjacent and distant fixed plate 7, and extrude and crush the agglomerated powder intercepted between the two adjacent fixed plates 7.

[0049] Example 2, reference Figure 9 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: a plurality of intercepting plates 12 are evenly distributed vertically between two adjacent fixed plates 7, and a through hole is provided in the extrusion plate 8 at a position corresponding to the intercepting plate 12. The intercepting plate 12 consists of a straight plate portion 121 and a triangular plate portion 122. A cutting blade 123 is provided on the side of the intercepting plate 12 facing the stirring blade 52.

[0050] Specifically, the interception plate 12 cooperates with the two fixed plates 7 to intercept smaller agglomerated powder materials, thereby improving the interception rate. During the process of being squeezed and crushed, the agglomerated powder materials can be cut by the setting of the cutting blade 123, thereby improving the crushing effect.

[0051] Among them, reference Figure 8 、 Figure 9 When the drive rod 93 is located in the arcuate groove, the extrusion plate 8 is located on the side of the straight plate portion 121. When the drive rod 93 completes sliding in the V-shaped groove, the extrusion plate 8 moves toward the triangular plate portion 122 and returns. When the extrusion plate 8 moves on the straight plate portion 121, it can pre-clamp smaller agglomerated powders. Subsequently, when the extrusion plate 8 moves on the triangular plate portion 122, the cutting blade 123 can divide the agglomerated powders, thereby achieving a crushed agglomerated powder under the extrusion and cutting effects. The remaining structure is the same as that of Example 1.

[0052] Example 3, reference Figure 9 , which is the third embodiment of the present invention, is different from the second embodiment in that a concave groove is provided on the side of the fixing plate 7 and the extrusion plate 8 facing the stirring blade 52, and an arc-shaped blade is provided at the concave groove.

[0053] Specifically, the provision of the concave groove can enhance the interception effect of agglomerated powder, preventing the fine powder from moving on the stirring blade 52 and driving the agglomerated powder away from the fixed plate 7. At the same time, the provision of the arc-shaped blade can preliminarily crush agglomerated powder with less agglomeration force, thereby reducing the subsequent crushing pressure. The remaining structure is the same as that of Example 2.

[0054] Comprehensive Examples 1-3, the working principle of the present invention is as follows: after the weighing powder in the weighing box 2 reaches a preset value, the feeding is stopped. When the discharge port of the weighing box 2 transports the powder into the heating tank, the motor drives the drive shaft 6 to rotate, the rotating shaft 1 61 cooperates with the face gear to drive the stirring member 5 to rotate, the rotating shaft 2 62 drives the guide wheel 112 to rotate, the guide wheel 112 cooperates with the wedge block 113 to drive the sleeve 3 to rise, and after the guide wheel 112 leaves the wedge block 113, the elastic member 43 resets to drive the sleeve 3 to descend rapidly, and generates vibration on the weighing box 2 to prevent the powder from adhering to the inner wall of the weighing box 2 As the stirring member 5 rotates, it follows the sleeve 3 to make a lifting motion. The inclined surface of the stirring blade 52 flips the powder upward, so that the powder in the weighing box 2 exchanges its position and the agglomerated powder is transported to the crushing mechanism. The multiple fixed plates 7 on the stirring blade 52 cooperate to intercept the agglomerated powder. When the driving rod 93 completes a sliding in the V-shaped groove, it can drive the connecting rod 94 to perform a horizontal reciprocating motion, so that the extrusion plate 8 moves to the side of the adjacent and distant fixed plate 7, and then returns to its original position, so that the intercepted agglomerated powder can be squeezed and crushed.

[0055] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
