Description

Technical Field

[0001] The utility model relates to the technical field of fireworks processing, in particular to a powder filling device which is convenient for compacting. Background Art

[0002] Fireworks, also known as fireworks, pyrotechnics, and firecrackers, are made from pyrotechnic powder and are entertainment products used to produce sound, light, and color. They are often used in grand ceremonies or performances. In order to achieve good performance effects, fireworks and display shells are filled with a large amount of gunpowder for launching and explosion.

[0003] At present, when fireworks are filled with gunpowder, a gunpowder storage box is usually arranged at the lower end of the bracket, and then a discharge pipe is arranged at the lower end of the gunpowder box, and then a cylinder is placed below the discharge pipe to store the gunpowder, thereby completing the work of gunpowder filling.

[0004] However, the above-mentioned filling device can only be used for filling when in use. After filling, since there is a lot of gunpowder and it is not dense, it needs to be compacted manually. However, there is a lot of gunpowder inside a part of the cylinder, which makes it impossible to compact it from the top, thereby reducing the use effect of the device. In view of this, we propose a filling device that is easy to compact. Utility Model Content

[0005] The purpose of the utility model is to provide a medicine filling device which is convenient for compaction, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a medicine filling device that is easy to compress, comprising a workbench, a bracket is fixedly installed on the upper end of the workbench, a medicine box is fixedly installed on the lower end of the bracket, a cylinder is arranged on the upper end of the workbench, and a compressing structure is arranged on the lower end of the bracket, and the compressing structure comprises:

[0007] An electric push rod, the electric push rod is fixedly mounted at the lower end of the bracket, a cylinder is fixedly mounted at the lower end of the output shaft of the electric push rod, a motor is fixedly mounted at the upper end of the cylinder, the motor output shaft passes through the inner wall of the cylinder and is fixedly mounted with a rotating rod, and a reciprocating screw is fixedly mounted on the surface of the rotating rod;

[0008] The sleeve is threadedly connected to the surface of the reciprocating screw rod, a connecting plate is fixedly installed on the side wall of the sleeve, a feeding rack is arranged at the lower end of the connecting plate, one end of a bellows is fixedly installed at the lower end of the medicine box, the other end of the bellows is fixedly connected to the upper end of the feeding rack, and a protective structure is arranged at the lower end of the connecting plate.

[0009] Preferably, the protective structure includes a directional cylinder penetrating the side wall of the connecting plate, the inner wall of the directional cylinder is slidably connected with a moving rod, the lower end of the moving rod is fixedly connected to the upper end of the unloading rack, and a return spring is arranged on the surface of the moving rod.

[0010] Preferably, a limit plate is fixedly mounted on the upper end of the moving rod, and a contact switch is fixedly mounted on the lower end of the connecting plate.

[0011] Preferably, the contact switch is electrically connected to the motor.

[0012] Preferably, one end of the return spring is fixedly connected to the lower end of the directional cylinder, and the other end of the return spring is fixedly connected to the upper end of the unloading rack.

[0013] Preferably, one end of a guide rod is slidably connected to the inner wall of the cylinder, and the other end of the guide rod is fixedly connected to the side wall of the sleeve.

[0014] Compared with the prior art, the utility model provides a medicine filling device that is easy to compress and has the following beneficial effects:

[0015] 1. The filling device that is easy to compress is provided with a compressing structure so as to facilitate sufficient compression of the gunpowder filled in the cylinder. When filling, the user can discharge the materials through the bellows, and then the gunpowder raw materials will be discharged and filled from the lower end of the discharge rack. After a certain amount of gunpowder is filled, the user can start the motor to work, and the motor rotation drives the rotating rod to rotate, thereby driving the sleeve and the discharge rack to move downward to compress the part of the gunpowder that has been filled in the cylinder. Therefore, the intermittent filling and compression can make the compression effect better, thereby avoiding the problem that there is too much gunpowder in part of the cylinder, which makes it impossible to compact it when it is subsequently compressed from the upper end.

[0016] 2. The charge-filling device that is easy to compress is provided with a protective structure so as to provide certain protection for the gunpowder raw materials when they are in contact with the unloading rack. When the unloading rack moves downward to compress the part of the gunpowder that has been filled in the cylinder, it is not completely hard squeezed, because the cylinder is usually not transparent. In order to avoid damage caused by squeezing too much gunpowder, after the unloading rack contacts the gunpowder, it can continue to move through the connecting plate so that the unloading rack and the gunpowder are squeezed tighter and tighter. After the unloading rack contacts the contact switch, the compaction work is completed, which further improves the use effect of the device. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] like Figure 1-Figure 3 As shown, the utility model provides a technical solution: a medicine filling device that is easy to compress, including a workbench 1, a bracket 2 is fixedly installed on the upper end of the workbench 1, a medicine box 5 is fixedly installed on the lower end of the bracket 2, a cylinder 6 is arranged on the upper end of the workbench 1, and a pressing structure 3 is arranged on the lower end of the bracket 2. The pressing structure 3 includes an electric push rod 31 fixedly installed on the lower end of the bracket 2, a cylinder 32 is fixedly installed on the lower end of the output shaft of the electric push rod 31, a motor 33 is fixedly installed on the upper end of the cylinder 32, the output shaft of the motor 33 passes through the inner wall of the cylinder 32 and is fixedly installed with a rotating rod 34, a reciprocating screw rod 35 is fixedly installed on the surface of the rotating rod 34, a sleeve 36 is threadedly connected on the surface of the reciprocating screw rod 35, a connecting plate 37 is fixedly installed on the side wall of the sleeve 36, a feeding frame 38 is arranged on the lower end of the connecting plate 37, one end of a bellows 39 is fixedly installed on the lower end of the medicine box 5, the other end of the bellows 39 is fixedly connected to the upper end of the feeding frame 38, and a protective structure 4 is arranged on the lower end of the connecting plate 37.

[0022] Specifically, the clamping structure 3 of the technical solution of the utility model includes: an electric push rod 31, a cylinder 32, a motor 33, a rotating rod 34, a reciprocating screw rod 35, a sleeve 36, a connecting plate 37, a feed rack 38, and a bellows 39.

[0023] In one embodiment of the utility model, a clamping structure 3 is provided to facilitate sufficient compression of the gunpowder filled in the cylinder 6, gunpowder raw materials are stored in the medicine box 5, and a bellows 39 is provided at the lower end of the medicine box 5 for unloading, and a unloading rack 38 is provided at the lower end of the bellows 39 for unloading raw materials into the cylinder 6, the unloading rack 38 is hollow inside and has several groups of openings at the lower end, and an electronic valve for controlling the opening and closing is provided inside the opening. When filling, the user can place the cylinder 6 under the cylinder 32, and then the user starts the electric push rod 31 to drive the cylinder 32 at its lower end to move downward, so that the cylinder 32 enters the cylinder 6, and then the user unloads through the bellows 39, and then the gunpowder raw materials are discharged from the lower end of the unloading rack 38 and filled into the cylinder 6.

[0024] After a certain amount of gunpowder is filled, the user can start the motor 33 to work. The model of the motor 33 is HG-JR353BK. The motor 33 provides power for the rotation of the rotating rod 34. The output shaft of the motor 33 rotates the rotating rod 34 at its lower end, and the reciprocating screw 35 on its surface is rotated by the rotation of the rotating rod 34. The sleeve 36 threaded on its surface is moved downward by the rotation of the reciprocating screw 35. The connecting plate 37 and the unloading rack 38 of the side wall are moved downward by the movement of the sleeve 36 to compact the part of the gunpowder that has been filled in the cylinder 6. Therefore, the intermittent filling and compacting can make the gunpowder compacting effect better, thereby avoiding the problem that there is too much gunpowder in part of the cylinder 6 and it cannot be compacted when compacted from its upper end later.

[0025] By setting up a protective structure 4, it is convenient to provide certain protection for the gunpowder raw material and the discharge rack 38 when they come into contact. The discharge rack 38 moves downward to compress the part of the gunpowder that has been filled in the cylinder 6. At this time, it is not a completely hard squeeze, because the cylinder 6 is usually not transparent. In order to avoid damage caused by excessive squeezing of gunpowder, after the discharge rack 38 comes into contact with the gunpowder, it can continue to move through the connecting plate 37 so that the discharge rack 38 and the gunpowder are squeezed tighter and tighter. At this time, the discharge rack 38 moves through the moving rod 42 and continues to squeeze the reset spring 43. After the discharge rack 38 comes into contact with the contact switch 8, the compaction work is completed, further improving the use effect of the device.

[0026] Please continue reading Figure 1-Figure 3 The protective structure 4 includes a directional cylinder 41 that passes through the side wall of the connecting plate 37. A moving rod 42 is slidably connected to the inner wall of the directional cylinder 41. The lower end of the moving rod 42 is fixedly connected to the upper end of the unloading rack 38. A return spring 43 is arranged on the surface of the moving rod 42. A limit plate 7 is fixedly installed on the upper end of the moving rod 42. A contact switch 8 is fixedly installed on the lower end of the connecting plate 37. The contact switch 8 is electrically connected to the motor 33. One end of the return spring 43 is fixedly connected to the lower end of the directional cylinder 41, and the other end of the return spring 43 is fixedly connected to the upper end of the unloading rack 38. One end of the guide rod 9 is slidably connected to the inner wall of the cylinder 32, and the other end of the guide rod 9 is fixedly connected to the side wall of the sleeve 36.

[0027] During operation, the cylinder 6 is placed under the cylinder 32, and then the electric push rod 31 is started to drive the cylinder 32 at its lower end to move downward into the cylinder 6, and then the material is discharged through the bellows 39, and then the raw material is discharged from the lower end of the unloading rack 38 and filled into the cylinder 6. After a certain amount of gunpowder is filled, the motor 33 is started to work, and the output shaft of the motor 33 is rotated to drive the rotating rod 34 to rotate, and the rotation of the rotating rod 34 drives the reciprocating screw rod 35 to rotate, and the rotation of the reciprocating screw rod 35 drives the sleeve 36 to move downward, and the sleeve 36 moves to drive the connecting plate 37 and the unloading rack 38 to move downward to compress the part of the gunpowder that has been filled in the cylinder 6. After the unloading rack 38 contacts the gunpowder, it can continue to move through the connecting plate 37, so that the unloading rack 38 and the gunpowder are squeezed more and more tightly. At this time, the unloading rack 38 moves through the moving rod 42 and continuously squeezes the reset spring 43. After the unloading rack 38 contacts the contact switch 8, the compacting work is completed, which further improves the use effect of the device.

[0028] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
