Description

Technical Field

[0001] The utility model relates to the field of spice preparation, in particular to a spice pressing mechanism. Background Art

[0002] During the production process, spices need to be mixed, sifted, stirred, formed, dried and packaged. Among them, during the spice forming process, the air in the spices needs to be discharged, otherwise the spices will break during the extrusion process.

[0003] To improve the molding quality of spices, the prior art provides a spice pressing mechanism comprising an extrusion barrel, a pressing rod, and a motor. The motor drives the pressing rod to move axially along the extrusion barrel, squeezing the spices within the barrel and expelling most of the air. When the squeezing reaches a certain level, the mutual pressure of the spices within the barrel forces the spices out of the molding hole into a strip. However, this spice pressing mechanism has the following technical problems in actual use:

[0004] Since the diameter of the pressing rod is close to the inner diameter of the extrusion barrel, most of the spices in the extrusion barrel will be subjected to a greater pressure from the pressing rod, and the spices closer to the inner wall of the extrusion barrel will be subjected to less pressure, and will be more likely to be squeezed out from the forming hole or the gap between the pressing rod and the inner wall of the extrusion barrel. On the contrary, the spices closer to the middle of the extrusion barrel will be squeezed more by the pressing rod and will be difficult to move, causing the air mixed in it to be trapped by the spices and difficult to discharge, resulting in insufficient exhaust effect of the spice pressing mechanism, and there will still be some air gaps in the spices, which will cause the prepared incense sticks to still break easily.

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] The utility model provides a spice pressing mechanism, which is used to solve the problem of how to improve the exhaust effect and prevent the prepared incense sticks from breaking easily.

[0042] See Figure 1 and Figure 3 As shown, Figure 1 This is a three-dimensional diagram of the spice pressing mechanism from the first perspective in the embodiment. Figure 3 1 is a partial structural cross-sectional view of the spice pressing mechanism in the embodiment, which includes a material box 1, an extrusion cylinder 2, a pressing rod 3, a driving member 4 and an exhaust rod 5.

[0043] The material box 1 is used to contain spices to be pressed and formed.

[0044] The extrusion cylinder 2 can be fixed on the outside of the material box 1 by screws or welding, and the extrusion cylinder 2 has an extrusion channel 21 communicated with the material box 1 and a discharge port 22 communicated with the extrusion channel 21 .

[0045] The pressing rod 3 includes a connecting end 31 and a free end 32 . The driving member 4 and the connecting end 31 of the pressing rod 3 can be fixedly connected by screws or welded. The driving member 4 is configured to drive the pressing rod 3 to move between the extrusion channel 21 and the material box 1 .

[0046] The exhaust rod 5 can be fixedly mounted on the free end 32 of the pressure rod 3 by screwing, welding or tight connection, and the axial direction of the exhaust rod 5 is parallel to the extension direction of the extrusion channel 21. It can be seen that the exhaust rod 5 is located in the middle of the extrusion channel 21.

[0047] When the spice pressing mechanism of the above technical solution is used, the driving part 4 drives the pressing rod 3 to move from the material box 1 into the extrusion channel 21, pushing the spices in the material box 1 into the extrusion channel 21. In the process of the pressing rod 3 penetrating the extrusion channel 21, the spices in the extrusion channel 21 are continuously squeezed. At the same time, the exhaust rod 5 moves with the pressing rod 3 and is inserted into the spices in the middle of the extrusion channel 21, further compacting the spices in the middle of the extrusion channel 21. The spices in the middle of the extrusion channel 21 can move along the insertion of the exhaust rod 5 and be discharged from the gap between the pressing rod 3 and the inner wall of the extrusion tube 2. The air entrained therein can also be discharged from the gap between the pressing rod 3 and the inner wall of the extrusion tube 2 along with the movement of the spices. After the spices are compacted to a certain extent, the pressing rod 3 continues to penetrate into the extrusion channel 21, driving the spices that cannot be further compacted to be squeezed downward from the discharge port 22 of the extrusion tube 2 and form a line, thereby making incense sticks. It can be seen that the spice pressing mechanism can further compact the spices in the extrusion channel 21 through the exhaust rod 5, and drive the spices in the middle of the extrusion channel 21 to move, further exhausting the air mixed in the spices, effectively improving the exhaust effect of the spice pressing mechanism, and greatly reducing the gaps in the spices, thereby improving the molding quality of the spices and making the prepared incense sticks less likely to break.

[0048] The exhaust rod 5 can be located in the center of the extrusion channel 21 or in an intermediate position close to the center of the extrusion channel 21. As is known from the background art, the closer the spices are to the center of the extrusion channel 21, the greater the pressure from the pressure rod 3, making it more difficult for them to move. Therefore, the closer the exhaust rod 5 is to the center of the extrusion channel 21, the more it can move the spices in the center of the extrusion channel 21, and thus the more it can drive the air trapped in the spices in the center of the extrusion channel 21 to be discharged, and the better the exhaust effect.

[0049] See Figure 3 and Figure 4 As shown, Figure 4 for Figure 3 In the enlarged schematic diagram at point A, in one embodiment of the exhaust rod 5, there are at least two exhaust rods 5 spaced apart, and the exhaust rod 5 includes a first end 51 connected to the free end 32 of the pressing rod 3, and a second end 52 arranged opposite to the first end 51, and the second end 52 is tapered. In this way, the tapered second end 52 can facilitate the exhaust rod 5 to continue to penetrate deeper into the increasingly compacted spices along with the pressing rod 3, further compacting the spices and driving the movement of the spices in the extrusion channel 21. The more exhaust rods 5 there are, the better the compaction effect on the spices in the extrusion channel 21, and the more spices in the extrusion channel 21 can be driven to move, thereby driving more air mixed in the spices to be discharged, further improving the exhaust effect of the spice pressing mechanism, and making the prepared incense stick less likely to break.

[0050] See Figure 3 and Figure 4As shown, the spice pressing mechanism also includes a discharge assembly head 6, which is installed at the discharge port 22 of the extrusion cylinder 2, and the discharge port 22 is distributed vertically downward, and the discharge assembly head 6 has a first tapered hole 61, a second tapered hole 62 and a forming hole 63, the first tapered hole 61, the second tapered hole 62 and the forming hole 63 are coaxially distributed and connected in sequence along the discharge direction, the cross-sectional aperture of the first tapered hole 61 and the second tapered hole 62 gradually decreases along the discharge direction, the first tapered hole 61 is connected to the extrusion channel 21, and is also spaced apart from the second tapered hole 62, the maximum aperture of the second tapered hole 62 is not less than the minimum aperture of the first tapered hole 61, the minimum aperture of the second tapered hole 62 is less than the minimum aperture of the first tapered hole 61, and the minimum aperture of the second tapered hole 62 is the same as the aperture of the forming hole 63. In this way, the discharge port 22 makes the discharge direction of the spices in the extrusion channel 21 vertically downward, greatly reducing the influence of the spices' own gravity on the shaping of the spices, avoiding the incense sticks from breaking due to their own gravity, and further making the manufactured incense sticks not easy to break; and in the process of the spices in the extrusion channel 21 being extruded from the discharge port 22, the first tapered hole 61 and the second tapered hole 62 can both shrink the discharge port 22, so as to further compact the spices extruded from the discharge port 22, and then shape the spices through the forming hole 63 and output the discharge combination head 6, wherein the first tapered hole 61 and the second tapered hole 62 are distributed at intervals, which can reduce the stroke of continuous compression and extrusion of the spices, thereby reducing the difficulty of discharging the spices, making it easier for the spices to be squeezed out of the discharge combination head 6, and greatly reducing the risk of the spices being blocked in the discharge combination head 6.

[0051] The first tapered hole 61 and the second tapered hole 62 do not affect the discharge of air in the extrusion channel 21 .

[0052] See Figure 3 and Figure 4 As shown, in one embodiment of the discharge combination head 6, the discharge combination head 6 includes a first discharge head 64 and a second discharge head 65. The first discharge head 64 can be fixedly installed at the discharge port 22 of the extrusion barrel 2 by screwing, snapping or nesting. The first tapered hole 61 is located on the first discharge head 64. The first discharge head 64 also has a mounting hole 66 connected to the first tapered hole 61. The second discharge head 65 can be detachably installed at the mounting hole 66 of the first discharge head 64 by screwing or snapping. The second tapered hole 62 and the forming hole 63 are both located on the second discharge head 65. In this way, the discharge combination head 6 can replace the second discharge head 65 with a different diameter of the forming hole 63, so that incense sticks with different cross-sectional diameters can be produced, which greatly improves the scope of application of the spice pressing mechanism.

[0053] The second discharge head 65 can be screwed into the mounting hole 66 of the first discharge head 64, allowing for removable attachment to the first discharge head 64. Rotating the second discharge head 65 relative to the first discharge head 64 allows for adjustment of the spacing between the first tapered hole 61 and the second tapered hole 62, thereby improving the quality of the incense stick. To facilitate the application of force to rotate the second discharge head 65, a handle 67 can also be welded to the second discharge head 65.

[0054] See Figure 1 and Figure 3 As shown, the spice pressing mechanism further includes a pressing barrel 7. Both the extrusion barrel 2 and the pressing barrel 7 can be fixedly mounted on the outside of the material box 1 via flange screws and are arranged relative to each other. The pressing barrel 7 has a receiving channel 71, which is coaxially distributed with the extrusion channel 21. The driving member 4 is mounted on the pressing barrel 7, and the output end 41 of the driving member 4 extends into the receiving channel 71 and is connected to the connecting end 31 of the pressing rod 3. The spice pressing mechanism also includes an initial state and a pressing state. In the initial state, the pressing rod 3 is partially or completely located within the pressing barrel 7. In the pressing state, the driving member 4 drives the pressing rod 3 out of the pressing barrel 7 and into the extrusion channel 21 from the material box 1. In this way, in the initial state, the pressing rod 3 can be partially or completely retracted within the pressing barrel 7, providing sufficient displacement space for the pressing rod 3 to perform the next pressing action. It also facilitates the movement of the pressing rod 3 to replenish the spices in the material box 1, so that the pressing rod 3 can push a large amount of spices from the material box 1 into the extrusion barrel 2 each time it presses.

[0055] The driving member 4 can be a reciprocating driving member such as a telescopic cylinder or an electric telescopic rod. The output end 41 of the driving member 4 can be welded to the connecting end 31 of the pressure rod 3 or fixed by screws.

[0056] See Figure 2 and Figure 3 As shown, Figure 2 This is a perspective view of the spice pressing mechanism in the embodiment from a second perspective. Based on the above embodiment, a clearance hole 72 is opened on the pressing barrel 7. The clearance hole 72 is used to discharge the spices in the pressing barrel 7. In this way, the clearance hole 72 can facilitate cleaning of the pressing barrel 7 and prevent the spices from filling the pressing barrel 7 and making it impossible to retract the pressing rod 3.

[0057] See Figure 2 As shown, based on the above embodiment, the spice pressing mechanism further includes a receiving box 8, which is placed below the clearance hole 72. In this way, the receiving box 8 can receive and collect the spices discharged from the clearance hole 72, effectively reducing spice waste and preventing spices from dripping onto the ground and dirtying the ground.

[0058] See Figure 1 and Figure 3As shown, in one embodiment of the extrusion barrel 2, the extrusion barrel 2 includes a barrel body 23 and a plug 24. One end of the barrel body 23 can be fixedly mounted on the outside of the material box 1 via a flange structure screw, and the plug 24 is sealed at the other end of the barrel body 23. In this way, if the plug 24 is removed from the end of the barrel body 23, and the pressure rod 3 is moved along the extension direction of the extrusion channel 21 and penetrates the barrel body 23, the fragrance adhering to the inner wall of the extrusion channel 21 can be scraped off, thereby achieving the effect of cleaning the inner wall of the extrusion channel 21.

[0059] In one embodiment of the plug 24, the plug 24 is integrally formed of an elastic material. Since the deeper the exhaust rod 5 is inserted, the better the exhaust effect. However, when inserted to the extreme position, the exhaust rod 5 will impact the plug 24, and the plug 24 will also generate a reaction force on the exhaust rod 5. Therefore, the plug 24 has elasticity, which can effectively buffer the impact force generated by the exhaust rod 5 insertion on the plug 24, thereby protecting both the exhaust rod 5 and the plug 24 itself.

[0060] The plug 24 may be made of a rubber material that has both elasticity and sealing properties.

[0061] See Figure 1 As shown, the spice pressing mechanism further includes a hopper 9 , which can be fixed to the material box 1 by bolts or welding. The hopper 9 serves as a guide to facilitate pouring the spice raw materials into the material box 1 .

[0062] See Figure 2 and Figure 3 As shown, in one embodiment of the material box 1, the material box 1 has a through-hole 11 for the pressure rod 3 to pass through. The through-hole 11 is coaxially distributed with the pressure rod 3, and the diameter of the through-hole 11 is the same as the diameter of the pressure rod 3. In this way, when the pressure rod 3 passes through the through-hole 11, the wall of the through-hole 11 can scrape off the spices adhering to the outer wall of the pressure rod 3, thereby performing a scraping function to prevent the pressure rod 3 from carrying the spices out of the material box 1 or the extrusion barrel 2.

[0063] There are two perforations 11 , one of which is located on the side wall of the material box 1 where the pressing cylinder 7 is installed, and is used to reduce the pressure rod 3 from bringing spices into the pressing cylinder 7 ; the other is located on the side wall of the material box 1 where the extrusion cylinder 2 is installed, and is used to reduce the pressure rod 3 from bringing spices out of the extrusion cylinder 2 .

[0064] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
