Description

Technical Field

[0001] This utility model relates to a double-sided cashmere blind stitching machine, specifically a feeding device for the double-sided cashmere blind stitching machine and the double-sided cashmere blind stitching machine itself. Background Technology

[0002] The feed port of a double-sided cashmere blind stitch machine requires a horizontal bar for pushing the fabric to be installed on the left side. This bar is at the same height as the presser foot block, which results in a very small gap between the bar and the worktable. If the worker's left hand is to perform other operations, it has to go around the bar from the left side, which greatly affects efficiency. Utility Model Content

[0003] To address the shortcomings of the prior art, this invention provides a feeding device for a double-sided cashmere blind stitching machine and the double-sided cashmere blind stitching machine itself. This invention provides sufficient operating space for the worker's left hand, greatly facilitating a series of operations with the left hand without affecting the feeding process.

[0004] To achieve the above technical objectives, the present invention adopts the following technical solution: a material pushing device for a double-sided cashmere blind stitch machine, comprising a material pushing component and a driving component. One end of the driving component is connected to the machine body of the blind stitch machine, and the other end drives the material pushing component, so that the material pushing component makes a horizontal linear movement to push the fabric. An operating space is left between the material pushing component and the table of the blind stitch machine, and the operating space is used to place the operator's left hand for sewing.

[0005] The material pushing component includes a fixed end and a material pushing rod. The fixed end, the material pushing rod, and the blind sewing machine table form the operating space. The fixed end and the material pushing rod are integrally formed or separately connected. The free end of the material pushing rod has a material pushing head, and the presser foot block has a material pushing opening. The material pushing head moves linearly within the material pushing opening to push the fabric.

[0006] The driving component is a swing arm. The first end of the swing arm receives an external force to make the swing arm rotate. The second end of the swing arm can contact the pushing component and drive the pushing component to move in a straight line.

[0007] The swing arm adopts a lever structure, with one end receiving external force and the other end equipped with a swing arm head for pushing the pusher component.

[0008] The lever structure includes a main arm and a secondary arm. The free end of the main arm receives external force, and the free end of the secondary arm is provided with a swing arm head for pushing the pusher component.

[0009] The swing arm head includes a stud, which is threaded to the free end of the auxiliary arm. The stud end face of the stud can push the pusher component. The stud can adjust the working length.

[0010] The swing arm head also includes an auxiliary rod, one end of which is hinged to the auxiliary arm, and the first surface of the other end can contact the stud end face of the stud, and the second surface can push the pusher component.

[0011] It also includes a base, which includes a fixed plate and a sliding base plate. The fixed plate is used to fix and connect the body of the blind seam sewing machine. The sliding base plate is fixed to the fixed plate. The material pushing component is slidably connected to the sliding base plate and can move linearly on the sliding base plate.

[0012] It also includes an auxiliary structure for reducing friction, a limiting structure for limiting the stroke of the pusher member, and a reset assembly for resetting the pusher member.

[0013] A double-sided cashmere blind stitching machine includes a machine body and a material pushing device for the machine. The machine body is provided with a cam, which is used to connect to the drive component, so that the drive component cyclically pushes the material pushing component to push the fabric.

[0014] In summary, this utility model achieves the following technical effects:

[0015] This invention provides an operating space below the material pusher component for the operator's left hand. Previously, double-sided cashmere blind stitch machines had a horizontal material pusher on the left side, with a height approximately equal to the presser foot. This resulted in a very small gap between the pusher and the machine table, insufficient for the operator's left hand. Since the left hand needs to perform material feeding and other operations within this gap, it affected the operator's efficiency. This invention provides sufficient operating space for the operator's left hand, greatly facilitating a series of left-hand operations without affecting the material pusher.

[0025] Example:

[0026] Figure 1 It is a material pushing device for a double-sided cashmere blind stitch machine, including a material pushing component 3 and a driving component. One end of the driving component is connected to the machine body of the blind stitch machine, and the other end drives the material pushing component 3, so that the material pushing component 3 makes horizontal linear motion to push the fabric. There is an operating space between the material pushing component 3 and the table of the blind stitch machine. The operating space is used to place the operator's left hand for sewing.

[0027] This invention provides an operating space below the material pusher component to accommodate the operator's left hand. Traditional double-sided cashmere blind stitch machines have a horizontal material pusher on the left side, almost as high as the presser foot. This results in a very small gap between the pusher and the machine table, insufficient for the operator's left hand. Since the left hand is needed for feeding and placing material within this gap, it affects the operator's efficiency. This invention provides sufficient operating space for the operator's left hand, greatly facilitating a series of operations without affecting the material pusher. The operating space for the operator's left hand can be understood as allowing the left hand to lie flat in and out of the space, or to be curled up within it to manipulate the fabric.

[0028] The pusher component 3 has a corner structure, and the space formed between this corner and the blind stitch machine table is considered the operating space. This corner can be an obtuse angle, a right angle, or even an acute angle, as long as it forms an operating space. This embodiment uses an obtuse angle as an example. This utility model replaces the pusher component with an obtuse angle structure, presenting as follows: Figure 2 In this configuration, the space at the obtuse angle is used for the worker's left-hand operation.

[0029] Figure 2 This is a schematic diagram of the assembly of the base and the pusher component. The pusher component 3 includes a fixed end 31 and a pusher rod 32. The fixed end 31 and the pusher rod 32 form an obtuse angle structure. The fixed end 31 and the pusher rod 32 are either integrally formed or separately connected. The free end of the pusher rod 32 has a pusher head 323, and the pressure foot block 4 has a pusher opening 41. Figure 1 (As shown), the pusher head 323 moves in a straight line within the pusher opening 41 to push the fabric.

[0030] This embodiment features a split-type connection, secured with bolts 33, and also equipped with oblong holes for easy position adjustment. The split-type structure allows for better installation and position adjustment.

[0031] Furthermore, the fixed end 31 can be a rod or a plate, and its function is to strengthen the strength and stability of the push rod 32. In this embodiment, it is a plate, which is better connected to the slider 13 of the base 1, resulting in better stability.

[0032] The push rod 32 includes a connecting section 321 and an obtuse-angle section 322, with an obtuse angle structure between the connecting section 321 and the obtuse-angle section 322. The connecting section 321 is fixed to the fixed end 31 by bolts 33, resulting in an obtuse angle structure between the obtuse-angle section 322 and the fixed end 31. The push head 323 is located at the free end of the obtuse-angle section 322 and is used for pushing materials, cooperating with the push port 41 of the pressure foot block 4.

[0033] The fixed end 31 of this utility model can be placed horizontally or tilted. In short, its obtuse angle can form enough space for left-hand operation with the table of the blind sewing machine. It is not limited to the position and style shown in the attached drawings of this embodiment.

[0034] like Figure 1 As shown, the driving component is a swing arm 2, which is hinged to the body / base 1 of the blind sewing machine. The first end of the swing arm 2 receives external force to make the swing arm 2 rotate, and the second end of the swing arm 2 can contact the pusher component 3 and drive the pusher component 3 to move linearly.

[0035] The swing arm 2 adopts a lever structure, which is hinged to the body / base 1 of the blind sewing machine. One end of the lever structure receives external force, and the other end is equipped with a swing arm head to push the pusher component 3.

[0036] Furthermore, Figure 3 This is a schematic diagram of a swing arm. The lever structure includes a main arm 21 and a secondary arm 22. The main arm 21 is hinged to the body of the blind sewing machine. The free end of the main arm 21 receives external force. The free end of the secondary arm 22 is equipped with a swing arm head for pushing the material pushing component 3.

[0037] When the swing arm 2 is hinged to the body of the blind seam sewing machine, a hinge shaft is already present on the body. When the swing arm 2 is hinged to the base 1, only the hinge shaft needs to be installed on the base. This embodiment takes the hinged connection to the body as an example. The attached diagram shows the structure of the hinged connection to the body, that is... Figure 1 The hinge hole 28 shown is hinged to the body.

[0038] The main arm 21 of this invention has a hinge hole 28 for hinged connection with a hinge shaft (not shown) on the body of the blind sewing machine to realize the swinging motion of the arm. The auxiliary arm 22 transmits the swinging motion to the pushing component. The free end of the main arm 21 receiving external force means that a force is applied to the main arm 21 from the outside, so that the swing arm 2 can swing.

[0039] Specifically, the swing arm head includes a stud 241, which is threaded to the free end of the auxiliary arm 22. The stud end face of the stud 241 can push the pusher component 3; the stud 241 can adjust the working length.

[0040] This utility model's swing arm head is used to push the material pushing component 3. This function is achieved using a stud 241. When the auxiliary arm 22 rotates and swings, the stud end face of the stud 241 provides a thrust to the material pushing component 3, causing it to move. The stud 241 can be adjusted in position to regulate the stroke of the pushing component 3 and the distance the fabric is pushed forward. A fixing nut 242 is also provided to fasten the stud 241 and prevent it from changing position on its own.

[0041] Furthermore, the swing arm head also includes an auxiliary rod 25. One end of the auxiliary rod 25 is hinged to the auxiliary arm 22, and the first surface 251 of the other end can contact the stud end face of the stud 241, while the second surface 252 can push the pusher component 3.

[0042] This utility model utilizes the hinge bolt 29 to achieve the hinged movement of the auxiliary rod 25. The free end of the auxiliary rod is located between the stud end face and the pusher component 3, which is used to enhance the stability of the pushing action and prevent the pusher component 3 from being damaged due to direct contact between the stud end face and the pusher component 3.

[0043] In addition, the swing arm 2 is equipped with a pulley 27 to receive external force. The pulley can reduce friction and make the drive smoother.

[0044] like Figure 1 As shown, it also includes a base 1. Figure 2 The base is shown. The base 1 includes a fixed plate 11 and a sliding base plate 12. The fixed plate 11 is used to fix and connect the body of the blind sewing machine. The sliding base plate 12 is fixed to the fixed plate 11. The material pushing component 3 is slidably connected to the sliding base plate 12 and can make linear movements on the sliding base plate 12.

[0045] The fixing plate 11 has holes 19 for connecting the body of the blind seam machine.

[0046] It also includes an auxiliary structure for reducing friction, a limiting structure for limiting the stroke of the pusher member 3, and a reset assembly for resetting the pusher member 3.

[0047] Among them, such as Figure 2 As shown, the auxiliary structure includes a slider 13 and a groove formed on the support plate 12. The slider 13 is slidably connected to the groove, and the slider 13 is also fixedly connected to the pusher component 3. The slider-groove structure can reduce friction, facilitate the smooth movement of the pusher component 3, and prevent jamming.

[0048] The swing arm 2 can either directly contact the pusher component 3, or push the pusher component 3 by pushing the slider 13, since the pusher component 3 is fixed on the slider 13, which reduces friction. This embodiment uses pushing the slider as an example.

[0049] The slider 13 is also equipped with a lever 14, which can contact the second end of the swing arm 2 and drive the slider 13 to move linearly under the drive of the swing arm 2. A pulley 14 is provided on the lever 14 to reduce friction. The pulley is in direct contact with the second surface 252 of the auxiliary rod 25 of the swing arm, which is easy to push and convenient to use.

[0050] The present invention uses a swing arm to push a pulley 14, thereby pushing a slider and reducing friction by using the pulley.

[0051] The limiting structure includes a front limiting block 17 and a rear limiting block 18, and the slider 13 moves linearly between the front limiting block 17 and the rear limiting block 18.

[0052] The reset assembly uses a reset spring 15, one end of which is connected to the base 1 and the other end to the pusher component 3. A hook post 16 is provided on the base, and an extension rod 35 is provided on the pusher component 3. The two ends of the reset spring are fixed to the hook post 16 and the extension rod 35 respectively, for resetting the pusher component.

[0053] Presser foot 4 is fixed to the body of the blind seam sewing machine.

[0054] A double-sided cashmere blind stitching machine includes a blind stitching machine body and a material pushing device for the double-sided cashmere blind stitching machine. The blind stitching machine body is provided with a cam (not shown), which is used to connect a pulley 27 of a drive component, so that the drive component cyclically pushes the material pushing component 3 to push the fabric.

[0055] This invention can be mounted on the body of a double-sided cashmere blind stitching machine, replacing the original horizontal, low-positioned push rod, leaving operating space and facilitating worker operation.

[0056] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
