Description

Technical Field

[0001] The utility model relates to the technical field of explosive production auxiliary equipment, in particular to an explosive extrusion molding device for explosive processing. Background Art

[0002] Special explosives for explosive processing are made by mixing and drying various raw materials, including the primary explosive, binder, plasticizer, desensitizer, and anti-aging agent. After mixing and drying, defects such as bubbles and voids may appear in the tablets, affecting their explosive performance. To ensure stable detonation and detonation transmission, the dried tablets must be rolled. This process eliminates bubbles and voids, increases density and elasticity, and improves the stability of detonation and detonation transmission. However, the required unit charge, length, thickness, and width of the explosives vary across different blasting operations. During the blasting operation, blasting operators can divide and combine the explosives. However, this not only increases the workload of blasting operators but also poses certain safety risks. Prior art equipment also employs mechanical structures to roll and cut tablets. However, most use separate cutting equipment for cutting and rolling equipment for tableting. Furthermore, the cut width and thickness after rolling are generally fixed, making them difficult to adapt to diverse production and use requirements.

[0035] like Figures 1 to 4 As shown, this embodiment provides an explosive processing explosive extrusion molding device, which includes a frame (not shown in the figure), an extrusion mechanism 1 and a splitting mechanism 2. The extrusion mechanism 1 is arranged on the frame, and the extrusion mechanism 1 includes at least one extrusion assembly 11. The extrusion assembly 11 includes a support frame 111 and two pressure rollers 112 that are spaced and rotatably arranged on the support frame 111 along the height direction. The length direction of the pressure roller 112 extends along the second direction. The second direction is Figure 1 In the X direction, the gap between the two pressing rollers 112 is adjustable, and the rotation directions of the two pressing rollers 112 are opposite. The tablet can be sandwiched between the two pressing rollers 112 and move along the first direction as the pressing rollers 112 rotate. The height direction is Figure 1 The Z direction in the first direction is Figure 1 The first direction is the Y direction, which is the direction in which the tablets are transported. The splitting mechanism 2 and the extrusion mechanism 1 are spaced apart on the frame along the first direction. The splitting mechanism 2 includes a splitting table 21 and at least one rotating blade 222 rotatably mounted on the splitting table 21. The tablets are supported on the splitting table 21 and cut as the rotating blade 222 rotates. The two pressing rollers 112 rotate to move the tablets held therein, thereby conveying the tablets. Simultaneously, the tablets are rolled by the two pressing rollers 112, thinning the tablets. Adjusting the height of the pressing rollers 112 allows for rolling of tablets of varying thicknesses, such as controlling the tablet thickness between 2 and 15 mm to meet different usage requirements. During tablet conveyance, the rotation of the rotating blade 222 cuts the tablets, dividing them into the desired width. This explosives extrusion molding device achieves simultaneous tablet conveying, rolling, and splitting, achieving integrated tablet molding, high processing efficiency, and reduced production time.

[0036] In this embodiment, in the conveying direction of the tablets, the splitting mechanism 2 is located upstream of the extrusion mechanism 1, that is, the tablets are rolled into shape by the extrusion mechanism 1 after being split, and the gap between the rotating blade 222 and the splitting table 21 is basically consistent with the thickness of the tablets to be processed, that is, there is no need to frequently adjust the height position of the rotating blade 222, saving debugging time.

[0037] Specifically, if Figure 1 and Figure 4 As shown, the splitting mechanism 2 also includes a splitting blade assembly 22, which includes a central column 221 and a plurality of rotating blades 222 detachably disposed on the central column 221 at intervals. The central column 221 is rotatably and detachably connected to the splitting table 21, and the rotation axis of the central column 221 is parallel to the rotation axis of the pressing roller 112. During use, the rotating blades 222 on the central column 221 are disassembled and assembled as needed. For example, if a tablet needs to be split into wider strips, the rotating blade 222 between two of the rotating blades 222 on the central column 221 is removed, and then the central column 221 is assembled. During operation, the distance between two adjacent rotating blades 222 is the width of the split strip. For example, by disassembling and assembling the rotating blades 222, the tablet width can be split into strips of 4-20 mm. Similarly, if a tablet needs to be split into narrower strips, one or more rotating blades 222 are installed between two adjacent rotating blades 222.

[0038] Optionally, the rotating blade 222 is a circular rolling blade, and the outer edge of the rolling blade is provided with oblique teeth to facilitate cutting.

[0039] Exemplarily, the dividing table 21 is set on the frame, and two supporting ear plates are erected on opposite sides of the dividing table 21. The central column 221 is rotatably and detachably connected between the two supporting ear plates, for example, through a bearing connection.

[0040] More specifically, the dividing mechanism 2 further includes a rotary motor, which drives the central column 221 to rotate, thereby driving the rotary blade 222 thereon to rotate.

[0041] In this embodiment, a central column 221 is provided with multiple stopper protrusions 211 spaced along its length. The rotating blades 222 have an inner ring that is designed to fit over the central column 221. These inner rings are provided with stopper grooves, each of which engages with a stopper protrusion 211. The stopper protrusions 211 are fixed in position. To adjust the tablet splitting width, the rotating blades 222 on the central column 221 are simply removed and installed as needed, adjusting the spacing between adjacent rotating blades 222 to the desired value. This makes adjustment simple, convenient, and easy.

[0042] Furthermore, if Figures 1 to 3As shown, the extrusion mechanism 1 may include one or more extrusion assemblies 11. When multiple extrusion assemblies 11 are provided, the multiple extrusion assemblies 11 are spaced apart on the frame along the first direction. For example, two or three extrusion assemblies 11 are provided, and the gap between the two pressing rollers 112 in each extrusion assembly 11 is adjustable. That is, the tablets are rolled by the multiple extrusion assemblies 11 along the conveying direction, and the tablets can be gradually extruded by adjusting the gap between the pressing rollers 112 in different extrusion assemblies 11, so that the thickness of the final formed tablets is more precise. For example, along the conveying direction, the gap between the pressing rollers 112 in the extrusion assembly 11 gradually decreases, and the tablets are gradually thinned, which is beneficial to improving the tablet forming quality. Preferably, a conveying platform 3 is provided between each two adjacent extrusion assemblies 11 for supporting the tablets.

[0043] Specifically, the extrusion mechanism 1 further includes at least one drive assembly 12, each drive assembly 12 corresponding to one extrusion assembly 11. The drive assembly 12 includes a driving member and a transmission member. The driving member is disposed on the frame and is connected to at least one pressing roller 112 through the transmission member to drive the at least one pressing roller 112 to rotate. The driving member provides power, which is transmitted through the transmission member to drive the pressing roller 112 to rotate, thereby achieving the conveying and rolling of the tablets.

[0044] Exemplarily, the transmission member includes a driving rod 121 and at least one driven gear 123. The driving member is rotatably connected to the driving rod 121 to drive the driving rod 121 to rotate. The driving rod 121 is provided with at least one driving gear 122. Each driven gear 123 is coaxially connected to a pressure roller 112 and meshes with a driving gear 122. When the driving member drives the driving rod 121 to rotate, the driving gear 122 on the driving rod 121 rotates, driving the meshed driven gear 123 to rotate, thereby driving the pressure roller 112 to rotate. The configuration of the driving rod 121 allows for two driving gears 122 to be simultaneously provided on it, thereby driving the two pressure rollers 112 to rotate simultaneously, improving the synchronization of the pressure rollers 112 and enhancing the compactness of the structure. The driving member may be, but is not limited to, a motor. Of course, in other embodiments, the drive assembly 12 may also have other structures, such as a rotary motor directly driving the pressure roller 112.

[0045] In this embodiment, in order to adapt to the adjustable height of the pressure roller 112, the position of the driving gear 122 on the driving rotating rod 121 along the height direction is adjustable to ensure that the driving gear 122 and the driven gear 123 on the pressure roller 112 are always reliably engaged, thereby ensuring the normal operation of the extrusion mechanism 1.

[0046] Preferably, the driving gear 122 and the driven gear 123 are both bevel gears, the driving gear 122 is in an inverted cone shape, and is located above the driven gear 123, that is, the driving gear 122 is pressed onto the driven gear 123, and the driving gear 122 is tightly attached to the driven gear 123 under the action of gravity, so that the engagement between the driving gear 122 and the driven gear 123 is reliable and stable.

[0047] For example, a ridge 1211 is provided along the length of the active rotating rod 121, and a sliding groove is provided on the inner ring of the sleeve of the active rotating rod 121. The sliding groove is adapted to be connected with the boss limiter and can slide along the ridge 1211. That is, when the height of the pressure roller 112 is adjusted, the active gear 122 slides down or lifts up accordingly, which is simple and convenient to operate and saves adjustment time.

[0048] More specifically, the extrusion assembly 11 further includes an adjustment member 114 and a support 113. The support 113 is slidably mounted on the support frame 111 in the height direction. The upper roller 112 of the two pressure rollers 112 is rotatably connected to the support 113. The adjustment member 114 is mounted on the support frame 111 and is drivably connected to the support 113 to drive the support 113 to slide in the height direction. The adjustment member 114 drives the support 113 to move in the height direction, thereby achieving height adjustment of the pressure roller 112.

[0049] For example, support frame 111 is a gantry mounted on a machine frame. Support 113 comprises a U-shaped plate 1131 and two L-shaped plates 1132 disposed on the back of U-shaped plate 1131. Press roller 112 is rotatably connected between U-shaped plates 1131. The two L-shaped plates 1132 are disposed opposite each other and form U-shaped grooves with the backs of U-shaped plates 1131. The two U-shaped grooves are slidably engaged with the two sides of the gantry. With this structure, support 113 has excellent structural stability, is stable and reliable when sliding along the height direction, and has good force uniformity.

[0050] In one embodiment, a threaded inner hole is provided on the support frame 111, such as the upper crossbeam of the gantry frame. A limit hole is provided on the support 113. The adjustment member 114 includes a stud, one end of which is rotatably connected to the support 113 through the limit hole, and the stud is threadedly connected to the threaded inner hole. When the stud rotates, the stud moves up and down along the threaded inner hole. Due to the limiting effect of the limit hole, the support 113 is driven to move up and down, that is, the support 113 is driven to slide in the height direction, thereby achieving height adjustment of the pressure roller 112.

[0051] Preferably, the adjusting member 114 further includes an adjusting disk and an adjusting handle. The adjusting disk is arranged at the other end of the stud, and the adjusting handle is eccentrically arranged on the adjusting disk. The adjusting handle facilitates the operator to rotate the stud.

[0052] In another embodiment, the adjusting member 114 may also be a manual screw lift or an electric screw lift, which drives the connecting support 113 to drive the support 113 to slide up and down. Since the manual screw lift or the electric screw lift is a relatively mature existing technology, they will not be described in detail here.

[0053] As will be appreciated, the explosive processing explosive extrusion molding device provided in this embodiment is manufactured entirely from non-pyrophoric materials, with electrical components such as the drive components utilizing explosion-proof electrical components, resulting in a high degree of intrinsic safety. The main components of the explosive processing explosive extrusion molding device, such as the frame, support frame 111, and support 113, are constructed from stainless steel. The pressure roller 112 is also constructed from stainless steel, and the rotating blade 222 is constructed from polytetrafluoroethylene (PTFE). Stainless steel is non-sparking, corrosion-resistant, and has a high hardness. PTFE is stable at room temperature and pressure, and offers excellent sealing, high lubricity, electrical insulation, and excellent aging resistance, facilitating post-production cleaning of the explosive processing explosive extrusion molding device.

[0054] Note that the above are merely preferred embodiments of the present invention and the technical principles employed. Those skilled in the art will appreciate that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments, and substitutions are possible for those skilled in the art without departing from the scope of protection of the present invention.
