Description

Technical Field

[0001] This utility model relates to an automatic granulation machine for fireworks sparkling beads, and in particular to a feeding device for a fireworks sparkling bead granulation tank. Background Technology

[0002] Existing automatic granulation machines for fireworks sparklers involve feeding raw materials into a granulation tank, which is then rotated by a drive device to granulate the sparklers. The granulation tank is a large, open disc, characterized by its large size and heavy weight. After granulation, the tank needs to be tilted to unload the sparklers onto a conveyor belt. This unloading process is inaccurate and prone to safety accidents. Summary of the Invention

[0003] The main purpose of this utility model is to provide a feeding device for a fireworks sparkler granulation tank, solving the technical problems of accurate, convenient and fast unloading.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A feeding device for a fireworks sparkler granulation tank includes a granulation tank with a feeding port. The feeding device includes a valve assembly disposed on one side of the feeding port, a rotating assembly connected to the outer wall of the granulation tank, and a driving device. The valve assembly is rotatably connected to the rotating assembly, and the driving device drives the valve assembly to rotate to close / open the feeding port.

[0006] Furthermore, the rotating assembly includes at least one fixed column fixedly connected to the outer wall of the granulation tank; the valve assembly includes at least one baffle that closes the discharge port; one end of the baffle closes the discharge port, and the other end is provided with a through hole, and the baffle is provided in a one-to-one correspondence with the fixed column; the fixed column passes through the through hole, and the side of the fixed column passing through the through hole is locked with a nut; the baffle rotates around the fixed column under the force of the driving device.

[0007] Preferably, the rotating assembly is a fixed column fixedly connected to the outer wall of the granulation tank; the valve assembly is a baffle with one end closing the discharge port and the other end having a through hole; the fixed column passes through the through hole; the side of the fixed column passing through the through hole is locked with a nut; the baffle rotates around the fixed column under the force of the driving device.

[0008] Preferably, the upper part of the fixing post is provided with a spring sleeve on the fixing post through the through hole opened on the valve assembly baffle, and an elastic washer is sleeved on the lower part of the through hole. One side of the elastic washer is tightened with a nut to fix the valve assembly baffle on the fixing post.

[0009] Preferably, the valve assembly further includes a first limiting plate and a second limiting plate vertically fixed under the baffle; the first limiting plate and the second limiting plate are arranged in parallel; the first limiting plate and the second limiting plate drive the baffle to rotate around the fixed column under the force of the driving device.

[0010] Preferably, the valve assembly includes a first baffle and a second baffle, one end of which closes the discharge port and the other end of which has a through hole; the first baffle and the second baffle are arranged side by side and adjacent to each other; a connecting spring is provided between the first baffle and the second baffle; and a third limiting plate is vertically connected to the lower part of the first baffle.

[0011] The rotating assembly includes a first fixed column and a second fixed column fixedly connected to the outer wall of the granulation tank; the first baffle and the second baffle are respectively arranged in a one-to-one correspondence with the first fixed column and the second fixed column; the first fixed column and the second fixed column respectively pass through the through holes of the first baffle and the second baffle; the first fixed column and the second fixed column are respectively locked and fixed with nuts on one side of the through holes of the first baffle and the second baffle.

[0012] The upper parts of the through holes of the first baffle and the second baffle are respectively fitted with the first gear and the second gear; the first gear and the second gear mesh with each other and move in opposite directions; the third limiting plate rotates under the force of the driving device, driving the first gear and the second gear to rotate, and driving the first baffle and the second baffle to rotate around the first fixed column and the second fixed column respectively.

[0013] The granulation tank has a discharge port, through which the granulated beads can be discharged, eliminating the need to tilt the granulation tank. A baffle is used to seal the discharge port of the granulation tank to prevent material leakage. The baffle acts as a door for the discharge port, and it opens by rotating. A fixed post on the side of the discharge port on the outer wall of the granulation tank serves as the rotating shaft of the door.

[0014] The fixing post passes through a through hole in the valve assembly baffle and is fitted with a spring at its upper part. An elastic washer is fitted at the lower part of the through hole, and a nut is tightened on one side of the elastic washer to fix the valve assembly baffle to the fixing post. The spring is used to adjust the clamping force of the baffle towards the feed port and also acts as a buffer when the baffle rotates under force.

[0015] When installing the spring, a non-metallic spacer can be fitted onto one end of the spring to isolate the spring from direct contact with the baffle, prevent metal-to-metal contact friction, and ensure safety.

[0016] Preferably, the driving device is a rotary pressing angle cylinder. A rotary pressing angle cylinder, also known as an angle cylinder, refers to a cylinder whose piston rod can rotate 90° to the right (or left) or other angles while extending and retracting. Its greatest advantage is that it has a rotary pressing action, realizing the function of rotation and clamping, possessing both radial rotational movement and axial clamping movement, thus pressing and fixing the target object.

[0017] The beneficial effects of this utility model are as follows: the granulation tank of this utility model has accurate, convenient and fast feeding, and simple structure. It can effectively eliminate safety hazards in the process of bright beads transfer, and will not cause material blockage and sedimentation during the opening and closing of the feeding port, thus ensuring safe production.

[0023] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings.

[0024] Example 1:

[0025] Reference Figure 1 The present invention relates to a feeding device for a fireworks sparkler granulation tank, comprising a granulation tank 2 with a feeding port 1, a valve assembly 3 on one side of the feeding port 1, the valve assembly 3 being a baffle, one end of the baffle of the valve assembly 3 sealing the feeding port 1, and the other end having a through hole (not shown in the figure).

[0026] A rotating assembly is installed on the outer wall of the granulation tank 2 near the discharge port 1. The rotating assembly includes a fixed column 4 welded to the outer wall of the granulation tank 2. The fixed column 4 passes through a through hole in the baffle of the valve assembly 3. A spring 5 is fitted onto the fixed column 4 at the upper part of the through hole, and an elastic washer 6 is fitted onto the lower part of the through hole. The elastic washer 6 is tightened with a nut 7, fixing the baffle of the valve assembly 3 to the fixed column 4. The spring 5 is fitted onto the fixed column 4 for buffering; by deforming the spring, it absorbs and releases energy, reducing the impact of the baffle of the valve assembly 3 on the fixed column and the granulation tank 2 when rotating. A rotary downward pressure cylinder 8 is installed below the end of the baffle of the valve assembly 3 where the through hole is located. The rotary downward pressure cylinder 8 is an automated actuator integrating rotary motion and linear downward pressure motion. The rotation direction of the rotary downward pressure cylinder is either left or right.

[0027] After the granulation tank 2 completes the granulation of fireworks beads, it stops rotating. The beads 9 accumulate inside the granulation tank 2. Upon receiving a command from the main controller, the rotary downward pressure cylinder 8 starts. The piston rod of the rotary downward pressure cylinder 8 extends upward. When the stop block on the piston rod rises to the left side of one end of the through hole of the valve assembly 3 baffle, the stop block rotates to the right, pushing one end of the valve assembly 3 baffle to rotate. Since the valve assembly 3 baffle is fixed to the fixed column 4 through the through hole, when the stop block rotates to the right, pushing one end of the valve assembly 3 baffle to rotate, the other end of the valve assembly 3 baffle (i.e., the end that closes the discharge port 1) rotates in the opposite direction, away from the position of the discharge port 1, until the valve assembly 3 baffle releases its sealing constraint on the discharge port 1. Without the sealing of the valve assembly 3 baffle, the beads 9 fall from the discharge port 1, completing the discharge.

[0028] After all the bright beads 9 in the granulation tank 2 are discharged, the piston rod of the rotating downward pressing angle cylinder 8 is compressed back down and then extended upward. During the upward extension of the piston rod, when the stop block reaches the right side of one end of the through hole of the valve assembly 3, the stop block rotates to the left to push one end of the valve assembly 3 baffle to rotate. Correspondingly, the other end of the valve assembly 3 baffle (i.e. the end that closes the discharge port 1) rotates in the opposite direction to reset, re-closing the discharge port 1. After the valve assembly 3 baffle is reset, the piston rod of the rotating downward pressing angle cylinder 8 is retracted back to its original position.

[0029] Example 2:

[0030] Reference Figure 2 This utility model discloses a feeding device for a fireworks sparkler granulation tank, comprising a granulation tank 2 with a feeding port 1, and a valve assembly 3 on one side of the feeding port 1. The valve assembly 3 includes a baffle 10, a first limiting plate 11, and a second limiting plate 12. The first limiting plate 11 and the second limiting plate 12 are installed parallel to each other on the lower part of the baffle 10 and are perpendicularly connected to the baffle 10. One end of the baffle 10 seals the feeding port 1, and the other end has a through hole (not shown in the figure).

[0031] A rotating assembly is installed on the outer wall of the granulation tank 2 near the discharge port 1. The rotating assembly includes a fixed column 4 welded to the outer wall of the granulation tank 2. The fixed column 4 passes through a through hole opened in the baffle 10. A spring 5 is installed at the upper part of the through hole and sleeved on the fixed column 4. An elastic washer 6 is sleeved at the lower part of the through hole. Figure 2 (Not shown in the drawing), tighten the elastic washer 6 with the nut 7 to fix the baffle 10 to the fixed post 4. The rotating downward pressing angle cylinder 8 is located below the middle position of the first limit plate 11 and the second limit plate 12.

[0032] After the granulation tank 2 completes the granulation of fireworks beads, it stops rotating. The beads 9 accumulate inside the granulation tank 2. After receiving the instruction from the main controller, the rotary downward angle cylinder 8 starts. When the piston rod extends upward to the middle position of the first limit plate 11 and the second limit plate 12, it rotates to the right. The cylinder stop block connected to the piston rod applies a force to the first limit plate 11, causing the valve assembly 3 to rotate as a whole until the baffle 10 releases the sealing constraint on the discharge port 1. The beads 9 fall from the discharge port 1, completing the discharge. After all the beads 9 in the granulation tank 2 have been discharged, the piston rod of the rotary downward angle cylinder 8 rotates to the left. The cylinder stop block connected to the piston rod applies a force to the second limit plate 12, causing the valve assembly to rotate in the opposite direction. The baffle 10 resets and re-closes the discharge port 1. After the baffle 10 resets, the piston rod of the rotary downward angle cylinder 8 resets.

[0033] Since the baffle 10, the first limiting plate 11 and the second limiting plate 12 of the valve assembly 3 are connected as a whole, the cylinder block of the rotating downward pressing angle cylinder 8 rotates left and right (i.e., swings back and forth) within the straight line range defined by the first limiting plate 11 and the second limiting plate 12 in parallel. During the rotation, it applies a force to the first limiting plate 11 and the second limiting plate 12, thereby driving the baffle 10 to close / open the feed port 1.

[0034] Example 3:

[0035] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4This utility model discloses a feeding device for a fireworks sparkler granulation tank, comprising a granulation tank 2 with a feeding port 1, and a valve assembly 3 disposed on one side of the feeding port 1. The valve assembly 3 includes a first baffle 17, a second baffle 18, and a third limiting plate 19 vertically installed below the second baffle 18. The first baffle 17 and the second baffle 18 are disposed adjacent to each other; a first spring 20 is transversely connected between the first baffle 17 and the second baffle 18. Through holes are formed on the first baffle 17 and the second baffle 18. A first fixing post 13 and a second fixing post 14 are welded side-by-side on the outer wall of the granulation tank 2 near the discharge port. The first fixing post 13 and the second fixing post 14 pass through through holes in the first baffle 17 and the second baffle 18, respectively. A first gear 15 and a second gear 16 are respectively fitted onto the first fixing post 13 and the second fixing post 14 above the through holes in the first baffle 17 and the second baffle 18. The first gear 15 and the second gear 16 are gears of the same size, meshing with each other, and rotating in opposite directions. Nuts are tightened at the lower parts of the through holes in the first baffle 17 and the second baffle 18, fixing the first baffle 17 and the second baffle 18 to the first fixing post 13 and the second fixing post 14, respectively. A rotating downward pressing angle cylinder 8 is installed below the third limiting plate 19.

[0036] After the granulation tank 2 completes the granulation of fireworks beads, it stops rotating. The beads 9 accumulate inside the granulation tank 2. Upon receiving a command from the main controller, the rotating downward-pressing angle cylinder 8 starts. When the piston rod extends upward to the position of the third limit plate 19, it rotates to the right. The cylinder stop block connected to the piston rod applies force to the third limit plate 19. Since the third limit plate 19 is connected to the second baffle 18, and the second gear 16 mounted on the second baffle 18 meshes with the first gear 15 mounted on the first baffle 17, when the second baffle 18 is subjected to force along with the third limit plate 19... The first gear 15 and the second gear 16 rotate in opposite directions. The first baffle 17 and the second baffle 18 rotate outward around the first fixed post 13 and the second fixed post 14 in opposite directions (i.e., facing away from each other). The first baffle 17 and the second baffle 18 move from an adjacent closed state to an open state until the first baffle 17 and the second baffle 18 release the sealing constraint on the discharge port 1. The bright bead 9 falls from the discharge port 1 without the sealing of the baffle 10, completing the discharge. The first spring 20 is stretched as the first baffle 17 and the second baffle 18 move in opposite directions.

[0037] After all the bright beads 9 in the granulation tank 2 are discharged, the piston rod of the rotating and pressing angle cylinder 8 retracts back to its original position. The third limit plate 19 loses the force of the cylinder block of the rotating and pressing angle cylinder 8, and the first spring 20 retracts accordingly. Under the action of the first spring 20, the first baffle 17 and the second baffle 18 rotate inward around the first fixed column 13 and the second fixed column 14 respectively, approaching each other and closing the discharge port 1 together.

[0038] It should be noted that all directional indicators (such as horizontal direction, vertical direction, parallel setting, vertical setting, up, down, left, right, front, back, inside, outside, etc.) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of each component in a certain specific posture. If the specific posture changes, the directional indicator will also change accordingly.

[0039] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0040] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
