Description

Technical Field

[0001] The utility model relates to the field of fireworks processing, in particular to a bonding device for fireworks production. Background Art

[0002] In the production process of large-scale fireworks, individual firework tubes need to be arranged and combined, and then the arranged firework tubes need to be glued together to prevent them from loosening when the fireworks are ignited. Traditional large-scale fireworks preparation requires manual arrangement of the firework tubes, preliminary bundling, and then manual gluing and fixing of the firework tubes. The production efficiency is low, and the existing gluing equipment has difficulty in keeping the firework tubes fixed during the gluing process, which easily leads to inaccurate gluing and poor gluing effect. Utility Model Content

[0003] In view of this, the utility model provides a bonding device for fireworks production, which can limit the fireworks tube when dispensing glue, so that the fireworks tube can remain fixed, facilitate more accurate glue dispensing, and improve the glue dispensing effect.

[0004] A bonding device for fireworks production includes a bracket with a groove formed on the bracket. Several firework tubes are placed in the bracket groove. A top plate is fixedly connected to the bracket. A dispensing mechanism and a limiting mechanism are provided on the bracket. The dispensing mechanism is used to dispense glue between the firework tubes. The limiting mechanism is used to limit the firework tubes so that the dispensing mechanism can better dispense glue to the firework tubes.

[0005] Further explanation, the dispensing mechanism includes a multi-stage sleeve hydraulic cylinder, the multi-stage sleeve hydraulic cylinder is fixedly connected to the bracket, the multi-stage sleeve hydraulic cylinder is fixedly connected to the glue box on the telescopic rod above, the multi-stage sleeve hydraulic cylinder is fixedly connected to the bottom of the telescopic rod below, the pressure plate and the glue box are slidingly connected, the telescopic rod below the multi-stage sleeve hydraulic cylinder extends into the glue box, and a number of dispensing heads are fixedly connected to the bottom of the glue box, and each of the dispensing heads is connected to the interior of the glue box.

[0006] Further description, a scraper block is also included, and each of the glue dispensing heads is fixedly connected to the scraper block.

[0007] Further description, the limiting mechanism includes a sliding rod, the sliding rod is slidably connected to the top plate, two return springs are connected between the sliding rod and the top plate, and two top rods are fixedly connected to the glue box.

[0008] It is further explained that the two push rods will squeeze the sliding rod when they descend.

[0009] Compared with the prior art, the utility model has the following advantages: 1. The telescopic rod at the top of the multi-stage sleeve hydraulic cylinder will extend and drive the glue box to descend. The descending of the glue box will drive the dispensing head and the scraper block to descend together. When the dispensing head descends between the fireworks tubes, the telescopic rod at the bottom of the multi-stage sleeve hydraulic cylinder will extend a certain distance. The telescopic rod at the bottom of the multi-stage sleeve hydraulic cylinder will extend and drive the pressure plate to descend. The descent of the pressure plate will squeeze the glue in the glue box. The glue in the glue box will be squeezed and flow out between the fireworks tubes through the dispensing head. In this way, automatic dispensing of the fireworks tubes can be achieved, thereby improving work efficiency.

[0010] 2. When the ejector rod descends, it squeezes the sliding rod, causing it to move closer to the firework tube. The return spring is compressed, and when the dispensing head moves to the designated position, the sliding rod contacts the compressed firework tube, restricting the firework tube and keeping it stationary. This allows the dispensing head to dispense glue to the firework tube more accurately, improving the dispensing effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Although the present invention may be described with respect to a specific application or industry, those skilled in the art will recognize the broader applicability of the present invention. Those skilled in the art will recognize that terms such as "above," "below," "upwardly," and "downwardly" are used to describe the drawings and are not intended to limit the scope of the present invention as defined by the appended claims. Numerical designations such as "first" and "second" are merely illustrative and are not intended to limit the scope of the present invention in any way.

[0019] Example 1: A bonding device for fireworks production, such as Figures 1-6 As shown, it includes a bracket 1 with a groove on it, and several firework tubes 2 are placed on the groove of the bracket 1. A top plate 101 is fixedly connected to the bracket 1. A dispensing mechanism and a limiting mechanism are provided on the bracket 1. The dispensing mechanism is used to dispense glue between the firework tubes 2, and the limiting mechanism is used to limit the firework tubes 2 so that the dispensing mechanism can better dispense glue to the firework tubes 2.

[0020] The dispensing mechanism includes a multi-stage sleeve hydraulic cylinder 3, the multi-stage sleeve hydraulic cylinder 3 is fixedly connected to the bracket 1, the multi-stage sleeve hydraulic cylinder 3 is fixedly connected to the telescopic rod above the multi-stage sleeve hydraulic cylinder 3 and the bottom of the telescopic rod below the multi-stage sleeve hydraulic cylinder 3 is fixedly connected to a pressure plate 5, the pressure plate 5 and the glue box 4 are slidably connected, the telescopic rod below the multi-stage sleeve hydraulic cylinder 3 extends into the glue box 4, and a number of dispensing heads 6 are fixedly connected to the bottom of the glue box 4, and each of the dispensing heads 6 is connected to the inside of the glue box 4.

[0021] It also includes a scraper block 7 , and each of the dispensing heads 6 is fixedly connected to the scraper block 7 .

[0022] At first, the glue box 4 is filled with glue, and the operator places the preliminarily bundled fireworks tubes 2 in the groove on the bracket 1. Then, the operator starts the multi-stage sleeve hydraulic cylinder 3, and the telescopic rod at the top of the multi-stage sleeve hydraulic cylinder 3 will extend. The telescopic rod at the top of the multi-stage sleeve hydraulic cylinder 3 will extend and drive the glue box 4 to descend. The descending of the glue box 4 will drive the dispensing head 6 and the scraping block 7 to descend together. When the dispensing head 6 descends between several fireworks tubes 2, the telescopic rod at the top of the multi-stage sleeve hydraulic cylinder 3 stops extending, and then the telescopic rod at the bottom of the multi-stage sleeve hydraulic cylinder 3 will extend a certain distance, and the telescopic rod at the bottom of the multi-stage sleeve hydraulic cylinder 3 will extend a certain distance. The extension will drive the pressure plate 5 to descend, and the descending pressure plate 5 will squeeze the glue in the glue box 4. The glue in the glue box 4 will be squeezed and flow out between several firework tubes 2 through the glue dispensing head 6. After the glue is dispensed, the telescopic rod of the multi-stage sleeve hydraulic cylinder 3 at the top will retract, and the telescopic rod of the multi-stage sleeve hydraulic cylinder 3 at the top will drive the glue box 4, the glue dispensing head 6 and the glue scraping block 7 to reset upward together. During the rising process of the glue scraping block 7, the glue on the firework tube 2 will be evenly scraped. Then the operator will remove the firework tube 2 with glue dispensed from the device and replace it with other firework tubes 2 to be bonded. This cycle is repeated. In this way, automatic glue dispensing of the firework tube 2 can be achieved, thereby improving work efficiency.

[0023] Example 2: Based on Example 1, Figure 2-Figure 6 As shown, the limiting mechanism includes a sliding rod 8, the sliding rod 8 is slidably connected to the top plate 101, two return springs 9 are connected between the sliding rod 8 and the top plate 101, and two top rods 10 are fixedly connected to the glue box 4.

[0024] The two push rods 10 descend and squeeze the sliding rod 8, so that the sliding rod 8 moves toward the direction of the firework tube 2. The sliding rod 8 contacts the firework tube 2, so that the firework tube 2 is restricted.

[0025] During the descending process of the glue box 4, the glue box 4 will drive the top rod 10 to descend. The descending top rod 10 will squeeze the sliding rod 8, causing the sliding rod 8 to move toward the direction close to the fireworks tube 2. The return spring 9 is compressed. When the dispensing head 6 moves to the specified position, the sliding rod 8 will contact the fireworks tube 2, so that the fireworks tube 2 will be restricted. When the top rod 10 moves upward and disengages from the sliding rod 8, the return spring 9 will drive the sliding rod 8 to reset, and the sliding rod 8 no longer restricts the fireworks tube 2. In this way, the fireworks tube 2 is restricted by the sliding rod 8, so that the fireworks tube 2 can remain fixed, so that the dispensing head 6 can more accurately dispense glue to the fireworks tube 2, thereby improving the dispensing effect.
