Description

Technical Field

[0001] This utility model relates to the field of needle punching machine technology, and in particular to a needle plate assembly for a filter bag needle punching machine. Background Technology

[0002] Needle punching machines are commonly used in the production of filter bags or non-woven fabrics. After the filter material of the filter bag is laid on the mesh, it is needle punched by the needle punching machine. The main drive of the needle punching machine is to drive the needle beam, needle plate and needle to move up and down together through the crank-connecting rod mechanism. When the needles penetrate the filter material, they insert the filter material fibers into the mesh. Through frequent up and down reciprocating motion, the filter material moves vertically towards the mesh, causing the fibers to shift up and down. The fibers that shift up and down exert a certain amount of pressure on the mesh, causing the fibers in the mesh to come together and be compressed, finally forming the filter cloth.

[0003] The needle plate assembly of current acupuncture machines, such as Figure 1 As shown, the needle plate assembly mainly includes a long strip-shaped fixing plate with several insertion holes. Each insertion hole is used to insert and fix a needle. A rubber buffer plate is provided at the bottom of the fixing plate. The fixing plate is provided with connecting screw holes and is fixed to the needle beam by bolts.

[0004] However, after a period of use, the needles may wear out or break. At this time, because the needles are arranged closely together, it is difficult to replace the needles in the middle. Therefore, if some needles are severely worn or broken, it is difficult to replace a single needle. The needles in the entire needle plate need to be replaced. The replacement time is long. Moreover, because the needles are dense and cover a large area, they will be interfered with by other needles during disassembly and replacement, making it difficult to replace a single needle or a partial replacement. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a filter bag needle plate assembly for easy replacement of needles, which solves the problem of difficulty in replacing single needles or partial replacements.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is: a needle plate assembly for a filter bag needle punching machine, comprising a fixing plate and a plurality of needles fixed on the fixing plate. The fixing plate includes a lower mounting plate, an upper cover plate, and a plurality of needle plates. The lower mounting plate is provided with two needle mounting areas and a fixing area located between the two needle mounting areas. Each needle mounting area is provided with a plurality of opening slots extending in the width direction, the width of the opening slots being adapted to the diameter of the needles. A plurality of needles are vertically inserted and fixed on each needle plate. The needles are arranged in rows and correspond to the opening slots. The needle plates are snapped onto the lower mounting plate from both sides. The upper cover plate is fixed on the fixing area and presses the needle plates tightly. Each row of needles is located in the corresponding opening slot. The upper cover plate is also provided with an installation connection structure for easy installation on a needle punching machine.

[0007] As a preferred embodiment, the needle plate is provided with an inner groove or inner protrusion on the side near the fixed area, and the inner grooves or inner protrusions on all needle plates in each needle installation area are arranged collinearly. The lower part of the upper cover plate is provided with an inner protrusion or inner groove that engages with the inner groove or inner protrusion.

[0008] As a preferred embodiment, the upper cover plate and the lower mounting plate are fixed together by bolts, and the mounting connection structure is a connecting screw hole provided on the upper cover plate.

[0009] As a preferred embodiment, the lower mounting plate is provided with a longitudinally extending outer groove on the outer side of the needle installation area, and the outer side of the needle plate is provided with an outer protrusion that engages with the outer groove, the outer protrusion being inserted into the outer groove from the lateral side.

[0010] As a preferred embodiment, the upper groove edge of the outer slot is located on the inner side of the side of the lower mounting plate, and the outer side of the installed needle plate is flush with the outer side of the lower mounting plate.

[0011] As a preferred embodiment, the inner side of the needle plate is provided with an installation step, and the inner groove or inner protrusion is provided on the installation step. The upper end surface of the upper cover plate after it is fixed is flush with the upper end surface of the needle plate.

[0012] As a preferred embodiment, the needle plate is provided with several rows of insertion holes, the needle is inserted into the insertion holes, and the upper end of the needle is provided with a bent section.

[0013] As a preferred embodiment, a buffer plate is bonded to the bottom of the lower mounting plate, and the buffer plate is also provided with a lower horizontal groove that corresponds one-to-one with the opening groove.

[0014] After adopting the above technical solution, the effect of this utility model is as follows: A filter bag needle punching machine needle plate assembly includes a fixed plate and several needles fixed on the fixed plate. The fixed plate includes a lower mounting plate, an upper cover plate, and several needle plates. The lower mounting plate is provided with two needle mounting areas and a fixed area located between the two needle mounting areas. Each needle mounting area is provided with several opening slots extending in the width direction. The width of the opening slots is adapted to the diameter of the needles. Several needles are vertically inserted and fixed on each needle plate. The needles are arranged in rows and are fixed to the needles. The needle plates are fitted onto the lower mounting plate from both sides, with the upper cover plate fixed to the fixed area and pressing the needle plates together. Each row of needles is positioned within its corresponding slot. The upper cover plate also features a mounting connection structure for easy installation on the acupuncture machine. Therefore, during use, all needles are inserted into and fixed onto the needle plates. Each needle plate can be fitted onto the lower mounting plate from both sides, with each row of needles inserted into its corresponding slot. The upper cover plate then secures and presses all the needle plates together. In this way, the needles can be directly connected to the needle beam of the acupuncture machine via the mounting connection structure. If a needle breaks and needs replacement, simply unscrew the upper cover plate to remove the corresponding needle plate from the side. Since the entire fixing plate is composed of multiple needle plates, their relatively small size makes replacing the needles easier, with less interference from surrounding needles. Furthermore, after prolonged use, when needing to replace needles, multiple needle plates can be replaced directly. This modular design facilitates needle replacement, especially suitable for replacing broken needles or needles in specific areas.

[0015] Furthermore, since the needle plate has an inner groove or inner protrusion on the side near the fixed area, and the inner grooves or inner protrusions on all needle plates in each needle installation area are arranged collinearly, and the lower part of the upper cover plate has an inner protrusion or inner groove that engages with the inner groove or inner protrusion, the engagement of the inner groove and the inner protrusion can further press the needle plate while restricting the lateral movement of the needle plate.

[0016] Furthermore, since the lower mounting plate is provided with a longitudinally extending outer groove on the outer side of the needle installation area, and the outer side of the needle plate is provided with an outer protrusion that engages with the outer groove, and the outer protrusion engages with the outer groove from the lateral side, when the needle plate is slid laterally from the side, the outer protrusion will engage with the outer groove and make full contact, indicating that the needle plate is in place. This makes it easier to assemble the upper cover plate and the needle plate.

[0017] Furthermore, since the upper groove edge of the outer slot is located on the inner side of the lower mounting plate, the outer side of the installed needle plate is flush with the outer side of the lower mounting plate. The inner side of the needle plate is provided with an installation step, and the inner groove or inner protrusion is provided on the installation step. The upper end face of the fixed upper cover plate is flush with the upper end face of the needle plate. In this way, the needle plate, upper cover plate, and lower mounting plate are combined into a structure with a flush upper surface and sides, resulting in a smoother overall surface.
