Detailed Implementation

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] like Figure 1-7 As shown, a fireworks and firecrackers pressing machine includes a base 1 and slots 12 arranged in a rectangular array on its top. Multiple guide rods 13 fixedly mounted on the top of the base 1 slide on pressing boxes 5 and pressing frames 6. A support plate 2 is provided between the pressing boxes 5 and the base 1, and multiple perforations on the support plate 2 each contain a support sleeve 3. These perforations match paper tubes 4 inserted into the slots 12, with the top of the paper tube 4 flush with the top of the support sleeve 3. By inserting the paper tubes 4 into the slots 12, and then placing the support plate 2 between the pressing boxes 5 and the base 1, with the paper tubes 4 passing through the multiple perforations on the support plate 2, the paper tubes 4 are positioned and supported to prevent tipping. The tops of the paper tubes 4 are protected by the support sleeves 3. The pressing is completed when the pressing frame 6 approaches the pressing box 5 to press the mud.

[0029] Specifically, the sliding method of the mud pressing frame 6 in the above technical solution can be electric push rod, motor combined with gears and racks; or any driving method known to those skilled in the art.

[0030] The mud pressing box 5 can slide by being pushed by an electric push rod, or by being pushed by the mud pressing frame 6; or by any driving method known to those skilled in the art.

[0031] As a further technical solution provided by this utility model, a wide-mouth part 23 is provided at the bottom of the support plate 2 on the side of the perforation.

[0032] Specifically, such as Figure 6 As shown, when the support plate 2 is placed on the base 1, the wide-mouth part 23 guides the paper tube 4 to a certain extent, and allows the paper tube 4 to be inserted more accurately into the multiple holes opened on the support plate 2.

[0033] Furthermore, a scraper ring 31 is hinged to the top of the support sleeve 3, and the scraper ring 31 covers the top of the paper tube 4 and the support sleeve 3 respectively.

[0034] Specifically, such as Figure 5 As shown, the top of the paper tube 4 and the top of the support sleeve 3 are blocked by the support sleeve 3, so as to avoid deformation of the paper tube 4 port caused by the mud pressing directly squeezing the top port of the paper tube 4 when the mud is pressed. After the mud pressing of the paper tube 4 is completed, the mud scraper ring 31 is rotated to scrape off the excess mud at the top of the paper tube 4, so that the mud at the end of the paper tube 4 is flat.

[0035] Furthermore, multiple support rods 22 are fixedly installed at the bottom of the support plate 2, and the support rods 22 are movably arranged in the positioning grooves 11 opened on the base 1. A baffle plate 21 is fixedly installed at the top of the support plate 2.

[0036] Specifically, by inserting the support rod 22 into the positioning groove 11, the position of the support plate 2 is positioned so that the paper tube 4 can be accurately aligned with the mud pressing box 5. At the same time, the baffle plate 21 fixedly installed on the top of the support plate 2 is used to collect the mud that falls from the mud pressing box 5 and the mud scraped off by the mud scraping ring 31, so as to prevent the mud from clogging the slot 12 and the positioning groove 11.

[0037] Furthermore, a spring 14 is sleeved on the outer wall of the guide rod 13, and multiple pressure rods 61 fixedly installed at the bottom of the mud pressing frame 6 are respectively movably arranged in the mud outlet holes 52 opened on the mud pressing box 5, and the mud outlet holes 52 are respectively matched with the through holes opened on the support plate 2.

[0038] Specifically, when the mud pressing frame 6 approaches the mud pressing box 5, multiple pressure rods 61 are respectively movably set on the mud outlet holes 52 opened on the mud pressing box 5. Under the obstruction of the mud in the mud outlet holes 52, the mud pressing box 5 is driven to move down and the spring 14 stores force. Then, when the mud pressing box 5 is attached to the baffle plate 21 on the support plate 2, the mud outlet holes 52 are aligned with the mud scraping ring 31 and the paper tube 4 respectively. The mud pressing frame 6 continues to move down so that the pressure rods 61 can squeeze the mud in the mud outlet holes 52 into the paper tube 4. Then the mud pressing frame 6 moves up and the spring 14 releases the stored force to push the mud pressing box 5 to move up and reset.

[0039] Furthermore, the bottom of the mud pressing box 5 is symmetrically and slidably equipped with acute-angled plates composed of horizontal plates 7 and inclined plates 71 on both sides of the mud outlet 52.

[0040] Specifically, the mud outlet hole 52 is blocked by the horizontal plate 7 on the two acute angle plates. Then, when mud is discharged from the mud outlet hole 52, the mud outlet hole 52 is opened by sliding the acute angle plates to press the mud. The use of the acute angle plates can reduce the problem of mud falling out of the mud pressing box 5 when it is not pressing the mud.

[0041] Furthermore, a tension spring 72 is fixedly installed between the upright plate 51 and the inclined plate 71 fixedly installed at the bottom of the mud pressing box 5.

[0042] Specifically, when the acute angle plate slides, the tension spring 72 deforms and stores force, and by bringing the two acute angle plates together, the mud remaining at the bottom of the mud outlet 52 can be scraped off to a certain extent, so that the mud outlet 52 will be smoother when it discharges mud next time.

[0043] Furthermore, the mud scraper ring 31 is movably mounted on the inclined plate 71.

[0044] Specifically, such as Figure 6 and Figure 7 As shown, when the mud pressing box 5 approaches the support plate 2, the mud scraper ring 31 squeezes out the inclined plates 71 on both sides of the bottom port of the mud hole 52, thereby causing the two horizontal plates 7 to slide open the mud outlet 52. At the same time, the tension spring 72 deforms and stores force. Then, when the mud scraper ring 31 disengages from the inclined plate 71, the tension spring 72 releases the stored force to push the two inclined plates 71 together and scrape away the mud remaining at the bottom port of the mud outlet 52.

[0045] Furthermore, the support sleeve 3 is rotatably mounted in the through hole on the support plate 2.

[0046] Specifically, the support sleeve 3 is screwed onto the support plate 2 to facilitate the maintenance and replacement of the deformed support sleeve 3.

[0047] Furthermore, the horizontal plate 7 and the inclined plate 71 are both made of stainless steel.

[0048] Working principle: By inserting paper tubes 4 into slots 12, and then placing support plates 2 between pressing boxes 5 and base 1, the paper tubes 4 are positioned and supported to prevent tipping through multiple holes on the support plates 2. Support sleeves 3 protect the top of the paper tubes 4. When the pressing frame 6 approaches the pressing box 5 to press mud, the scraper ring 31 squeezes out the inclined plates 71 on both sides of the bottom port of the mud outlet 52, causing the two horizontal plates 7 to slide open the mud outlet 52. Simultaneously, the tension spring 72 deforms and stores force. Then, when the scraper ring 31 disengages from the inclined plates 71, the tension spring 72 releases its stored force to push the two inclined plates 71 together and scrape away some of the mud remaining at the bottom port of the mud outlet 52. The support sleeves 3 shield the top of the paper tubes 4 and the top of the support sleeves 3, thus preventing deformation of the paper tube 4 port caused by direct pressure from the pressing mud during pressing. After the mud is pressed into the paper tube 4, the mud scraper ring 31 is rotated to scrape off the excess mud at the top of the paper tube 4, thus making the mud at the end of the paper tube 4 smooth. After the mud is pressed into the paper tube 4, the support plate 2 is lifted and moved to facilitate the sorting and collection of the exposed paper tube 4.

[0049] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
