Description

Technical Field

[0001] This utility model mainly relates to the field of fireworks manufacturing machinery technology, and in particular to an auxiliary device for changing the inner cylinder propellant mold for fireworks effects. Background Technology

[0002] In the automated production line for filling propellant into the inner tube of fireworks effects, the filling mold for the inner tube of fireworks effects needs to be changed accordingly in order to adapt to different models of inner tubes of fireworks effects.

[0003] In existing technology, the replacement of the inner tube propellant mold for fireworks effects is done entirely manually by workers. However, because the inner tube propellant mold for fireworks effects is made of metal and is quite heavy, it often requires at least two workers to work together to complete the replacement. More importantly, the fully manual replacement method demands a high level of skill and coordination from the workers; otherwise, misalignment or mismatch between the inner tube propellant mold and the propellant loading mechanism can easily occur, leading to difficulties in accurately filling the inner tube with propellant during the loading process, thus affecting the quality of the finished fireworks.

[0004] It is evident that the existing method of manually changing the inner tube of the fireworks effect mold has many drawbacks. Therefore, there is a need for an auxiliary device that can free up manpower and improve the positioning accuracy of the inner tube of the fireworks effect mold. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide an auxiliary device for changing the inner cylinder of fireworks effect explosive mold.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A firework effect inner cylinder charging mold replacement auxiliary device includes a base, on which a bracket for supporting and fixing the firework effect inner cylinder charging mold is slidably installed in the transverse direction, and the moving path of the bracket passes through a charging mechanism fixedly connected to the base.

[0008] The auxiliary device for replacing the inner tube of the fireworks effect propellant mold disclosed in this application uses a bracket with a moving path that can pass through the propellant loading mechanism to support and fix the inner tube of the fireworks effect propellant mold. When replacing the inner tube of the fireworks effect propellant mold, the worker only needs to drag the bracket to pull the old inner tube of the fireworks effect propellant mold out of the propellant loading mechanism, then remove it from the bracket, place the new inner tube of the fireworks effect propellant mold on it, and then gently push the bracket to push the new inner tube of the fireworks effect propellant mold onto the propellant loading mechanism. Generally speaking, this process can be completed by only one worker. Therefore, on the one hand, it reduces the labor intensity of manually handling the inner tube of the fireworks effect propellant mold, and on the other hand, the auxiliary device for replacing the inner tube of the fireworks effect propellant mold is accurately positioned, reducing the placement error of manual handling.

[0009] In the aforementioned auxiliary device for changing the inner cylinder propellant mold for fireworks effects, preferably, a foot cup with height adjustment function is installed at the bottom of the base.

[0010] The base is equipped with a height-adjustable stem cup, which can be used to adjust the height of the base to adapt to different workbench heights or uneven ground, thus enhancing the base's applicability and practicality.

[0011] In the above-mentioned auxiliary device for changing the inner cylinder of the fireworks effect, preferably, the base is formed on one side along the moving path of the bracket with a fixed seat for connecting the charging mechanism.

[0012] The fixed base can be connected to the charging mechanism with bolts to form an integrated structure, which increases the overall structure and allows for pre-positioning, avoiding the impact of the base moving back and forth on the accuracy of changing the inner cylinder charging mold of the fireworks effect.

[0013] In the above-mentioned auxiliary device for changing the inner cylinder of the fireworks effect, preferably, at least one pair of sliders are provided on the top of the base, and the sliders are installed in conjunction with the linear slide rails provided at the bottom of the bracket.

[0014] At least one pair of sliders are symmetrically arranged along the horizontal central axis of the base, and the linear slide rail at the bottom of the bracket is installed in cooperation with them. By simply pushing and pulling the bracket, the linear slide rail can be driven to slide back and forth along the slider, thus completing the pushing of the fireworks effect inner cylinder charge mold supported by the bracket.

[0015] In the above-mentioned auxiliary device for changing the inner tube of the fireworks effect propellant mold, preferably, a pair of positioning plates for fixing the position of the inner tube of the fireworks effect propellant mold are installed on the bracket. The positioning plates are located on the front side of the inner tube of the fireworks effect propellant mold and are arranged on the left and right sides of the inner tube of the fireworks effect propellant mold. The positioning plates abut against the front edge of the inner tube of the fireworks effect propellant mold and the lateral edge of its location.

[0016] By setting up positioning plates, the placement of the inner cylinder propellant mold for fireworks effects can be standardized and fixed, preventing the inner cylinder propellant mold from shifting and affecting the accuracy of subsequent propellant loading.

[0017] In the above-mentioned auxiliary device for changing the inner cylinder of the fireworks effect, preferably, the positioning plate is formed with a first obliquely arranged waist hole, and a screw for connecting the positioning plate and the bracket is inserted in the first waist hole.

[0018] The positioning plate is connected to the bracket through the inclined first waist hole and screws to form an integral structure. By setting the inclined first waist hole, the distance between the two positioning plates can be changed by changing the position of the screw in the waist hole, thereby adapting to the inner tube filling mold of fireworks effect of different widths.

[0019] In the above-mentioned auxiliary device for changing the inner tube of the fireworks effect, preferably, the auxiliary device for changing the inner tube of the fireworks effect further includes a limiting mechanism for limiting the sliding distance of the bracket. The limiting mechanism includes a limiting plate disposed on the base and a limiting post disposed on the bracket. The limiting plate is located on the moving path of the limiting post.

[0020] The limiting mechanism serves two purposes: firstly, it limits the sliding distance of the bracket to prevent it from slipping off the slider; secondly, by adjusting the position of the limiting plate, i.e., changing the maximum distance between the limiting post and the limiting plate, it determines the position where the bracket pushes the inner cylinder of the fireworks effect to the charging mechanism, thus meeting the requirement for precise placement of the charging mold.

[0021] In the above-mentioned auxiliary device for changing the inner cylinder of the fireworks effect, preferably, the limiting plate is formed with a second waist hole arranged along the moving path of the bracket, and a screw for connecting the limiting plate and the base is inserted in the second waist hole.

[0022] The limiting plate is provided with a second waist hole along the moving path of the bracket, and the length of the second waist hole is slightly smaller than the width of the bottom end of the limiting plate. The fixed point of the second waist hole can be moved along the moving direction of the bracket, thereby meeting the requirements of different charging mechanisms for the placement accuracy of the inner cylinder charging mold of the fireworks effect.

[0023] In the above-mentioned auxiliary device for changing the inner tube of the fireworks effect, preferably, the auxiliary device for changing the inner tube of the fireworks effect further includes a locking mechanism for restricting the sliding of the bracket. The locking mechanism includes a locking buckle provided on the base and a locking post provided on the bracket, which can be loosely fastened together.

[0024] When changing the inner tube of the fireworks effect mold, simply loosen the locking buckle on the locking post to push the mold forward. When the inner tube mold does not need to be changed, the locking buckle can be engaged with the locking post to prevent the bracket from sliding along the slide rail and affecting the normal operation of the charging mechanism.

[0025] In the aforementioned auxiliary device for changing the inner cylinder propellant mold for fireworks effects, preferably, the propellant loading mechanism includes a front bright bead propellant loading machine, a rear bright bead propellant loading machine, an opening propellant loading machine, and a sealing agent filling machine connected in series via an inner cylinder cake conveying device, all four of which are fixedly connected to the base of an auxiliary device for changing the inner cylinder propellant mold for fireworks effects.

[0026] The front bright bead loading machine, rear bright bead loading machine, package opening and loading machine, and sealing agent filling machine are all fixedly connected to the base of a firework effect inner tube loading mold changing auxiliary device. On the one hand, this avoids the firework effect inner tube loading mold changing auxiliary device moving back and forth between different workstations, thus preventing it from affecting the working efficiency of the loading mechanism. On the other hand, the fixed connection between the base and the loading mechanism only requires one positioning to meet the subsequent needs for precise pushing of the firework effect inner tube loading mold, making operation simpler. Furthermore, the loading mechanism of this application separates the traditional bright bead loading mechanism into a front bright bead loading machine and a rear bright bead loading machine, making the firework effect inner tube more uniform and improving the loading quality of the firework effect inner tube.

[0027] Compared with the prior art, the advantages of this utility model are:

[0028] This utility model discloses an auxiliary device for replacing the inner tube propellant mold for fireworks effects. It employs a bracket with a moving path that can pass through the propellant loading mechanism to support and fix the inner tube propellant mold. When replacing the inner tube propellant mold, the worker only needs to drag the bracket to pull the old mold out of the loading mechanism, remove it from the bracket, place the new mold on top, and then gently push the bracket to push the new mold onto the loading mechanism. Generally, this process can be completed by one worker. Therefore, it reduces the labor intensity of manually handling the inner tube propellant mold and also provides precise positioning, minimizing placement errors during manual handling.

The moving path of the bracket 3 passes through the charge mechanism 4 which is fixedly connected to the base 1.

[0037] In this embodiment, a height-adjustable foot cup 11 is installed at the bottom of the base 1. The height of the base 1 can be changed by adjusting the height of the foot cup 11, making the base 1 suitable for different workbench heights or uneven ground.

[0038] In this embodiment, a fixing seat 12 for connecting the loading mechanism 4 is formed on one side of the base 1 along the moving path of the bracket 3. The fixing seat 12 can be fixed to one end of the loading mechanism 4 by bolt connection.

[0039] In this embodiment, at least one pair of sliders 13 are provided on the top of the base 1, and the sliders 13 are installed in conjunction with the linear slide rail 31 provided at the bottom of the bracket 3.

[0040] In this embodiment, a pair of positioning plates 32 are installed on the bracket 3 to fix the position of the inner tube of the fireworks effect explosive mold 2. The positioning plates 32 are located on the front side of the inner tube of the fireworks effect explosive mold 2 and are arranged on the left and right sides of the inner tube of the fireworks effect explosive mold 2. The positioning plates 32 abut against the front edge and the lateral edge of the inner tube of the fireworks effect explosive mold 2. When installing the inner tube of the fireworks effect explosive mold 2, it is only necessary to place the inner tube of the fireworks effect explosive mold 2 on the bracket 3 and make its front edge and lateral edge abut against the positioning plates 32 to achieve positioning and fixation.
