Description

Technical field:

[0001] The utility model relates to the technical field related to embroidery machines, and more specifically to a novel suspension frame component of an embroidery machine. Background technology:

[0002] When a conventional embroidery machine is embroidering, the embroidery frame moves by friction on the table with the felt on the bottom. The friction resistance is large and the frame movement response is slow, which affects the improvement of embroidery accuracy and embroidery speed.

[0003] With the development of ultra-high-speed embroidery machines, the speed increase of the embroidery machine spindle has put higher and higher requirements on the response speed of the embroidery frame. In order to match the operation of ultra-high-speed embroidery machines, it is necessary to design a suspended embroidery frame structure that does not rub against the table or reduces friction.

[0004] The existing suspended embroidery frame needs to be installed with a guide rail, and the existing guide rails include round steel bars, steel bars with V-shaped guide grooves, or steel bars with U-shaped protrusions. Therefore, according to the design requirements, the profile strips of the suspended embroidery frame must have corresponding installation grooves or installation positions inside. The existing profile strips can only be suitable for installing one (round steel bars) or two guide rails (steel bars with V-shaped guide grooves or steel bars with U-shaped protrusions), and cannot be used for the profile strips of the above three guide rails at the same time;

[0005] Meanwhile, the existing suspended embroidery frame is generally formed into a rectangular frame by four profile strips, and the adjacent ends of two adjacent profile strips are in a right angle shape. At this time, it is necessary to fix the right angle piece on the top surface of the adjacent part by bolts, which not only makes the top surface of the suspended embroidery frame higher, but also the right angle piece added here will affect the aesthetics of the entire suspended embroidery frame. Generally, it is necessary to design the top surface, design some appearance patterns, etc., to improve the aesthetics, which increases the processing difficulty of the right angle piece and increases the processing cost;

[0006] In addition, when the existing suspended embroidery frame is in use, when the length of the cloth to be clamped is shorter than the width of the suspended embroidery frame, it cannot be clamped. At this time, an intermediate baffle bar needs to be provided in the middle of the suspended embroidery frame, and a clamping block needs to be installed between the intermediate baffle bar and the corresponding profile bar of the suspended embroidery frame for clamping. The existing clamping block is generally a steel block or a plastic block. For the steel block, the clamping part of the suspended embroidery frame is deformed when clamped (the suspended embroidery frame is an aluminum alloy frame, and its strength is lower than that of the steel block). When the plastic block is clamped, it is not strong enough, so it is easy to deform or break after multiple clamping, which makes it difficult to clamp firmly, easy to loosen, and has a short service life. Utility model content:

[0007] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a novel embroidery machine suspension frame assembly, wherein the profile bar is suitable for round steel bars, steel bars with V-shaped guide grooves and steel bars with U-shaped protrusions, and has a wide range of adaptability. At the same time, the L-shaped connecting plate at the bottom fixes two adjacent profile bars to the angle iron to improve their strength, so that the top surface of the adjacent ends of the two adjacent profile bars does not need to be installed with a connecting plate, thereby ensuring the aesthetics of the embroidery frame body, and the connecting plate only needs a horizontal plate, which is easy to manufacture and has a low manufacturing cost.

[0008] The solution of the utility model to solve the technical problem is:

[0009] A novel embroidery machine suspension frame assembly comprises an embroidery frame body, wherein the embroidery frame body is formed by four profile strips fixed to each other to form a rectangular frame;

[0011] A plurality of long slots are formed on the profile strip above the long installation groove, and two adjacent profile strips are spliced ​​at right angles;

[0012] In two adjacent profile strips, the elongated slot of one profile strip is connected with the corresponding elongated slot of the other profile strip and is at a right angle. One side of the plurality of angle irons is inserted into one end of the corresponding elongated slot of one profile strip, and the other side is inserted into one end of the corresponding elongated slot of the other profile strip.

[0013] The long installation grooves at the ends of the two adjacent profile strips form an L-shaped groove portion, and the L-shaped connecting plate is inserted into the L-shaped groove portion. The connecting plate is fixed to the corresponding angle iron and profile strip by fixing bolts.

[0014] The embroidery frame body is provided with a middle baffle, and the top surfaces of the front and rear ends of the middle baffle are both fixed with clamps, which are clamped on the profile strips extending left and right at the front or rear of the embroidery frame body.

[0015] The chuck includes a main connecting part and a clamping part. A horizontal extension part is formed at one end of the main connecting part close to the middle baffle, and the horizontal extension part is fixedly connected to the top surface of the front end or the rear end of the middle baffle by bolts. A first arc groove is formed at the lower part of the end surface of the main connecting part away from the middle baffle, and a clamping part is fixedly connected to this end surface by bolts. A second arc groove is formed at the lower part of the end surface of the clamping part facing the first arc groove. The long raised strip of the front or rear profile strip is located at the corresponding first arc groove and the second arc groove and is clamped between the corresponding inner side walls of the first arc groove and the second arc groove.

[0016] The main connecting part and the clamping part are both plastic parts. An inner metal reinforcement plate is arranged inside the clamping part, and a horizontal metal reinforcement plate is fixed at the top surface connection of the horizontal extension part.

[0017] The outstanding effects of the utility model are:

[0019] 2. It fixes two adjacent profile strips to the angle iron through the L-shaped connecting plate at the bottom to improve its strength, so that the top surface of the adjacent ends of the two adjacent profile strips does not need to be installed with a connecting plate, thereby ensuring the aesthetics of the embroidery frame body. Moreover, the connecting plate only needs a horizontal plate, which is easy to manufacture and has a low manufacturing cost.

[0020] 3. Its chuck includes a main connecting part and a clamping part, and an inner metal reinforcing plate is provided inside the clamping part, and a horizontal metal reinforcing plate is fixed at the top surface connection of the horizontal extension part, thereby improving the strength of the chuck and making it not easy to deform. When it is clamped on the long raised strip of the profile strip, the profile strip will not be deformed. At the same time, the internal strength is guaranteed, the clamping and fixing effect is guaranteed, and its service life is improved. Description of the drawings:

[0031] For example, see Figures 1 to 10 As shown, a novel embroidery machine suspension frame assembly includes an embroidery frame body 10, wherein the embroidery frame body 10 is formed by four profile strips 20 fixed to each other to form a rectangular frame, wherein the four profile strips 20 include two profile strips 20 extending left and right corresponding to the front and back and two profile strips 20 extending front and back corresponding to the left and right, and two adjacent profile strips 20 are vertically connected at right angles;

[0032] The bottom surface of the profile strip 20 is formed with an upwardly extending long installation groove 21 in the middle, and the two opposite inner side walls of the long installation groove 21 are formed with side long grooves 22 for installing the round steel guide rail (the inner side wall of the side long groove 22 is an arc-shaped wall surface), and the top surface of the long installation groove 21 is formed with an upper long installation groove 23 in the middle;

[0033] like Figure 3 As shown, the round steel guide rail is installed in the corresponding side elongated groove 22, so that it can be used for the movement of the slider using the round steel guide rail as the guide rail. The round steel guide rail is inserted into the annular groove on the outer side wall of the guide wheel of the slider to achieve support and guidance;

[0034] like Figure 4 As shown, V-shaped steel bars with guide grooves on both sides are fixed on the bottom surface of the upper elongated mounting groove 23, so that it can be used for the movement of a slider using the steel bars as guide rails, and the outer wall of the guide wheel of the slider is inserted into the corresponding V-shaped guide groove to achieve support and guidance.

[0035] like Figure 5 As shown, a steel bar with U-shaped protrusions on both sides is fixed on the bottom surface of the upper elongated mounting groove 23, so that it can be used for the movement of a slider that uses the steel bar as a guide rail, and the U-shaped protrusion is inserted into the annular groove on the outer wall of the corresponding guide wheel of the slider to achieve support and guidance.

[0036] This profile strip 20 is suitable for three types of guide rails and has a wide range of adaptability.

[0037] Furthermore, a plurality of elongated slots 24 are formed on the profile strip 20 above the elongated installation groove 21 (in this embodiment, two elongated slots 24 are formed on the upper part of each profile strip 20 for installing the angle iron 30, and a middle through slot is formed between the two elongated slots 24, and the middle through slot has no other function), and two adjacent profile strips 20 are spliced ​​at right angles;

[0038] In two adjacent profile strips 20, the elongated slot 24 of one profile strip 20 is connected with the corresponding elongated slot 24 of the other profile strip 20 and is at a right angle. One side of the angle iron 30 is inserted into one end of the corresponding elongated slot 24 of one profile strip 20, and the other side is inserted into one end of the corresponding elongated slot 24 of the other profile strip 20.

[0039] The elongated mounting grooves 21 at the ends of the two adjacent profile strips 20 that are close to each other form an L-shaped groove portion, and the L-shaped connecting plate 40 is inserted into the L-shaped groove portion. The top surface of the connecting plate 40 is pressed against the top surface of the L-shaped groove portion, and the bottom surface of the angle iron 30 is pressed against the bottom surface of the corresponding elongated slot 24. The supporting portion formed on the profile strip 20 between the elongated slot 24 and the corresponding elongated mounting groove 21 is clamped between the connecting plate 40 and the angle iron 30 through a plurality of fixing bolts, and the three are fixed to each other. The fixing is firm and the installation is convenient. The connecting plate 40 is not above the profile strip 20, so that the top surface at the corner of the embroidery frame body 10 is flat and beautiful. The connecting plate 40 only needs a horizontal plate, and the manufacturing is simple, the manufacturing cost is low, and the effect is good.

[0040] Furthermore, a radial extension portion 11 parallel to the profile strip 20 is formed on the inner side of the profile strip 20 of the embroidery frame body 10, and an elongated raised strip 12 for fixing the cloth clip is formed on the inner top surface of the radial extension portion 11 (part of the surface of the elongated raised strip 12 is formed with a toothed groove for improving the clamping friction), the top surface of the elongated raised strip 12 is an arc-shaped wall surface, and the wall surface on the inner side of the elongated raised strip 12 is formed with an elongated groove 13.

[0041] The top surface of one side of the radial extension part 11 near the profile strip 20 is formed with an elongated reinforcement part 14 extending upward, and the middle part of the elongated reinforcement part 14 is formed with an elongated reinforcement groove 15. The elongated reinforcement grooves 15 of two adjacent profile strips 20 are connected at one end and form an L-shaped groove. The reinforcing L-shaped angle iron block 60 is inserted into the L-shaped groove and fixedly connected to the two elongated reinforcement parts 14 by bolts. This further increases the connection firmness between the two adjacent profile strips 20 of the embroidery frame body 10.

[0042] Furthermore, a middle baffle 70 is placed in the embroidery frame body 10 , and clamps 80 are fixed to the top surfaces of the front and rear ends of the middle baffle 70 , and the clamps 80 are clamped on the profile strips 20 extending left and right at the front or rear of the embroidery frame body 10 .

[0043] The top surfaces of the left and right sides of the middle baffle 70 are both formed with first long protruding strips 71 extending forward and backward. The top surface of the first long protruding strip 71 is an arc surface. The side walls at the outer sides of the two first long protruding strips 71 are formed with first long grooves 72.

[0044] The clamp 80 includes a main connecting portion 81 and a clamping portion 82. A horizontal extension portion 83 is formed at one end of the main connecting portion 81 close to the middle baffle 70. The horizontal extension portion 83 is fixedly connected to the top surface of the front end or rear end of the middle baffle 70 by bolts. A first arc groove 84 is formed at the lower part of the end surface of the main connecting portion 81 away from the middle baffle 70. A clamping portion 82 is fixedly connected to this end surface by bolts. A second arc groove 85 is formed at the lower part of the end surface of the clamping portion 82 facing the first arc groove 84. The long raised strip 12 of the front or rear profile strip 20 is located at the corresponding first arc groove 84 and second arc groove 85 and clamped between the corresponding inner side walls of the first arc groove 84 and second arc groove 85.

[0045] The main connecting part 81 and the clamping part 82 are both plastic parts. The interior of the clamping part 82 is provided with an inner metal reinforcement plate 1 (during injection molding, the inner metal reinforcement plate 1 is placed inside the clamping part 82 and injection molded together). A horizontal metal reinforcement plate 2 is fixed to the top surface connection of the horizontal extension part 83, and during injection molding, the horizontal metal reinforcement plate 2 and the horizontal extension part 83 are injection molded together.

[0046] When the clamp 80 is in use, the bolts connecting the clamping portion 82 and the main connecting portion 81 can be loosened to place the elongated protruding strip 12 of the front or rear profile strip 20 at the corresponding first arc groove 84 and second arc groove 85, and then the corresponding bolts can be tightened to bring the first arc groove 84 and second arc groove 85 close to each other, so that the elongated protruding strip 12 of the front or rear profile strip 20 can be clamped between the inner side walls of the corresponding first arc groove 84 and second arc groove 85 to achieve fixation.

[0047] Since the main connecting portion 81 and the clamping portion 82 are both plastic parts, they will not deform the surface of the corresponding profile strip 20. At the same time, the horizontal metal reinforcement plate 2 can ensure that the horizontal extension portion 83 is not easily deformed, damaged, or loosened when fixed to the middle baffle 70, thereby ensuring a firm connection and increasing the service life of the clamp 80.

[0048] The upper part of the first arc groove 84 of the main connecting part 81 is formed with a horizontally extending long protrusion, and the upper part of the second arc groove 85 of the corresponding clamping part 82 is formed with a horizontally extending long positioning groove. The long protrusion is inserted into the long positioning groove, which plays a positioning effect during connection.
