Problems solved by technology

Chinese patent 200520050804.9 discloses an automatic loading device for fireworks. The loading process has been automated. The guide sleeve at the discharge port of the trough-shaped material channel has a certain shape to prevent some paper tubes with small ellipticity and curvature to prevent the tube from jamming. However, because the size of the guide sleeve is fixed, when encountering paper tubes with large ellipticity and curvature and paper tubes with large diameter tolerances, the phenomenon of card stoppage still occurs from time to time; for diameters smaller than the guide The paper tube with the inner diameter of the sleeve can not play the role of guiding and shaping; and because the position of the guide sleeve is fixed, the paper tube must pass through the guide sleeve to be sent to the seat. In this way, the outer wall of the paper tube with a larger diameter There will be strong friction with the inner wall of the guide sleeve, which will cause the deformation of the paper tube body and affect the alignment of the paper tube with the seat; all of these greatly restrict the further improvement of production efficiency and increase the labor intensity of workers

Embodiment 1

[0023] Refer to attached figure 1 , 2 , the present embodiment includes a frame 1, a cylinder body shaping mechanism, and the cylinder body shaping mechanism is arranged at the discharge port of the trough-shaped material channel 5 of the upper cylinder device of the fireworks and firecracker machine, and it includes a shaping jacket 8, a slide rod 9, and is sleeved on the The sliding sleeve 11 on the sliding rod 9, the cam drive mechanism I6, the outer side of the sliding sleeve 11 is covered with an annular sleeve 10, the shaping jacket 8 is composed of two semi-circular sleeves, and the semi-circular sleeve on one side is installed by a fixed arm 12-1 On the sliding sleeve 11, the other side of the semi-circular sleeve is installed on the annular sleeve 10 through another fixed arm 12-2, and a replaceable bushing 17 is arranged inside the shaping jacket, and the sliding sleeve 11 is hinged on the frame 1 The shift lever 4 on the top is connected with the cam driving mechan...

Embodiment 2

[0026] refer to Figure 4 The difference between the structure of this embodiment and Embodiment 1 is that the opening and closing mechanism of the shaping collet 8 consisting of a compression spring 13' and a backguy 14' is located at the lower part of the sliding sleeve 11, and the fixing arm 12-1' of the shaping collet 8, 12-2' is in the shape of a scissors fork, and the intersection is movably sleeved on the sliding sleeve 11, and the driving mechanism is a hydraulic cylinder 24. All the other are with embodiment 1.

Embodiment 3

[0028] refer to Figure 4 , the structure of this embodiment differs from that of Embodiment 2 in that the compression spring 13' Figure 4 The position shown is moved to the upper part of the sliding sleeve 11. All the other are with embodiment 2.

Abstract

The invention discloses fireworks cylinder automatic re-shaping device. It includes frame, and cylinder re-shaping mechanism which is set at discharging port and includes re-shaping jacket, driving mechanism. The re-shaping jacket is formed by two semi-circle jackets respectively set on the jacket seat by the two fixing arms between which there is open and close mechanism connected with the driving mechanism. The invention can be used in the fireworks cylinder with certain size to prevent stopping drive caused by cylinder blocking, further increase production efficiency, and reduce labor intensity for worker.

Description

technical field [0001] The invention relates to a fireworks barrel shaping device for a fireworks and firecracker machine, in particular to an automatic fireworks barrel shaping device for a fireworks and firecracker machine. Background technique [0002] Fireworks and firecrackers have a long history in our country, and they are deeply loved and welcomed by people all over the world. In the production process of various fireworks, one of the important processes is to put a proper amount of mud in the fireworks paper tube and compact it. This process has traditionally been done manually. Chinese patent 200520050804.9 discloses an automatic loading device for fireworks. The loading process has been automated. The guide sleeve at the discharge port of the trough-shaped material channel has a certain shape to prevent some paper tubes with small ellipticity and curvature to prevent the tube from jamming. However, because the size of the guide sleeve is fixed, when encountering...
