Description

Technical Field

[0001] This invention relates to the field of textile equipment technology, and more specifically, to a needle punching device. Background Technology

[0002] The process of weaving fabric into a finished product requires multiple sets of equipment. To transfer the fabric from one process to the next, a needle-punching mechanism is used to grip the fabric, ensuring that only one layer is gripped at a time. In real life, the needles of the needle-punching mechanism can also be used to pierce objects that can return to their original shape after being released (such as fabric or sponge), thus moving the object and facilitating its transport.

[0003] The needle punching mechanism includes two rows of needles. Each row of needles includes two rows of needles with opposite inclinations and intersecting needle tips. Each needle row includes multiple needles spaced apart. When the fabric needs to be moved, the needles on the two needle rows of each row simultaneously thrust downwards in a crisscross pattern along their needle shafts to pierce the fabric placed below the needle tips, thus moving the fabric. However, because the needles on the two needle rows intersect in an X-shape after being thrust out, the distance between the piercing holes of the needles on the two needle rows in the fabric is small, resulting in a dense distribution of piercing holes in the fabric below the two needle rows. This makes the fabric below the two needle rows prone to tearing when the fabric is heavy (e.g., a 50-pound sack of granules). Summary of the Invention

[0004] The main objective of this invention is to provide a needle-punching device to solve the problem that needle-punching mechanisms in the prior art are prone to damaging fabrics when gripping heavier fabrics.

[0005] To achieve the above objectives, the present invention provides a needle-piercing device, comprising: a housing, which is movably and reciprocatingly disposed in a vertical direction; two drive plates, which are disposed within the housing at a predetermined distance along a first predetermined direction, each drive plate having a downwardly inclined pin at its bottom, the pins on the two drive plates having opposite inclination directions, each pin having an inclination angle of 45°, and the two drive plates being movably disposed facing each other or away from each other along a second predetermined direction; wherein each pin has a first state of being inserted into a component to be inserted, and a second state of being separated from the component to be inserted, so that the pin can switch to the first state by moving downward in a vertical direction through the housing, while the two drive plates move towards each other along the second predetermined direction; wherein the first predetermined direction, the second predetermined direction, and the vertical direction are arranged perpendicularly to each other.

[0006] Furthermore, the acupuncture device also includes a transmission component, which is movably disposed within the housing. Both drive plates are connected to the transmission component. One of the drive plates is movably disposed to reciprocate along a second preset direction to drive the transmission component to rotate around a preset axis, so that the transmission component drives the other drive plate to reciprocate along the second preset direction. The two drive plates move in opposite directions along the second preset direction.

[0007] Furthermore, the acupuncture device also includes two transmission columns, and the transmission column is provided with two strip grooves, which are respectively located on both sides of the preset axis. The two transmission columns are arranged in a one-to-one correspondence with the two drive plates, and each transmission column is located on the corresponding drive plate. Each transmission column can slide through the corresponding strip groove.

[0008] Furthermore, the acupuncture device also includes a first guide member, which is disposed inside the housing. The first guide member has two circumferential sidewalls arranged opposite each other along a first preset direction. Each circumferential sidewall is provided with a first groove, which extends along a second preset direction. Each drive plate is provided with a first guide portion, and the two first guide portions and the two first grooves are arranged in a one-to-one correspondence. Each first guide portion cooperates with the corresponding first groove.

[0009] Furthermore, a guide post is provided at the top of the first guide member, and a guide hole is provided in the middle of the transmission member. The guide post and the guide hole are inserted and connected to connect the transmission member and the first guide member.

[0010] Furthermore, the housing includes a top plate and four side plates, each side plate extending vertically. The four side plates are connected to the four circumferential sidewalls of the top plate. The four side plates include a first side plate, a second side plate, a third side plate, and a fourth side plate connected in sequence. The first side plate and the third side plate are arranged opposite each other on both sides of the second side plate along a second preset direction. The second side plate and the fourth side plate are arranged opposite each other on both sides of the first side plate along a first preset direction. A second guide groove is provided on the second side plate, and a third guide groove is provided on the fourth side plate. Both the second guide groove and the third guide groove extend along the second preset direction. Each drive plate is provided with a first guide portion and a second guide portion arranged opposite each other along the second preset direction. The second guide groove cooperates with the second guide portion of the drive plate closest to the second side plate, and the third guide groove cooperates with the second guide portion of the drive plate closest to the fourth side plate.

[0011] Furthermore, the needle-punching device also includes two needle groups, with the two needle groups and two drive plates arranged one-to-one. Each needle group includes multiple needles, and each drive plate is provided with multiple through holes. The multiple through holes on each drive plate are arranged one-to-one with the multiple needles of the corresponding needle group. Each needle passes through the corresponding through hole so that the needles of each needle group are connected to the corresponding drive plate. The multiple through holes on each drive plate are arranged in an arc shape, and the center of the arc is located on the side of the drive plate near the transmission component.

[0012] Furthermore, one of the two drive plates is the first drive plate, and the other drive plate is the second drive plate. The needle-punching device also includes a first drive member, a transmission block, and a transmission shaft. The transmission block is drivenly connected to the first drive member, and the transmission shaft extends in a vertical direction. Both ends of the transmission shaft are connected to the transmission block and the transmission column on the first drive plate, respectively, so that the first drive member drives the transmission block to move in a second preset direction, so that the transmission block drives the transmission shaft and the first drive plate to move in the second preset direction.

[0013] Furthermore, the acupuncture device also includes a second driving member and a transmission disk. The second driving member is drivenly connected to the transmission disk, and the transmission disk is connected to the top plate of the housing, so that the second driving member drives the housing to move through the transmission disk.

[0014] Furthermore, the acupuncture device also includes multiple connecting shafts, which are spaced apart along the circumferential direction of the transmission disc. The first end of each connecting shaft is connected to the transmission disc, and the second end of each connecting shaft is connected to the top plate.

[0015] According to the technical solution of the present invention, the needle punching device includes a housing and two drive plates. Each drive plate has a downwardly inclined needle at its bottom. The housing drives the two drive plates to move downward in the vertical direction, while the two drive plates move towards each other in a second preset direction, so that the needles on each drive plate switch to a first state. Since the two drive plates are set at a preset distance along the first preset direction, the needles on the two drive plates in the first state can be prevented from crossing in an X shape. The distance between the insertion holes of the needles on the two drive plates on the workpiece to be inserted is not too small, and the insertion holes on the workpiece to be inserted are not too dense. Thus, the problem that the needle punching mechanism in the prior art is prone to damage to the fabric when gripping heavy fabrics is solved. Attached Figure Description

[0027] Please refer to Figures 1 to 5 This invention provides a needle-piercing device, comprising: a housing, which is movably and reciprocatingly arranged in a vertical direction; two drive plates 20, which are arranged at a predetermined distance within the housing along a first predetermined direction, each drive plate 20 having a downwardly inclined needle 41 at its bottom, the needles 41 on the two drive plates 20 having opposite inclination directions, each needle 41 having an inclination angle of 45°, and the two drive plates 20 being movably arranged facing each other or away from each other along a second predetermined direction; wherein each needle 41 has a first state of being inserted into a component to be inserted, and a second state of being separated from the component to be inserted, so that the housing moves downward in a vertical direction while the two drive plates 20 move towards each other along the second predetermined direction, so that the needle 41 switches to the first state; wherein the first predetermined direction, the second predetermined direction, and the vertical direction are arranged perpendicularly to each other.

[0028] The needle punching device of the present invention includes a housing and two drive plates 20. Each drive plate 20 has a downwardly inclined needle 41 at its bottom. The housing drives the two drive plates 20 to move downward in the vertical direction. At the same time, the two drive plates 20 move towards each other in a second preset direction, so that the needles 41 on each drive plate 20 switch to a first state. Since the two drive plates 20 are arranged at a preset distance along the first preset direction, the needles 41 on the two drive plates 20 in the first state can be prevented from crossing in an X shape. The distance between the insertion holes of the needles 41 on the two drive plates 20 on the workpiece to be inserted is too small. The insertion holes on the workpiece to be inserted are not too dense. Thus, the problem that the needle punching mechanism in the prior art is prone to damage to the fabric when gripping heavy fabrics is solved.

[0029] Specifically, the first preset direction is as follows: Figure 1 The x-direction is shown, and the second preset direction is as follows: Figure 1 y direction shown.

[0030] Specifically, the tilt angle of each pin 41 refers to the angle between each pin 41 and the bottom plane of the drive plate 20, and the bottom plane of the drive plate 20 extends horizontally; the two drive plates 20 are set at a preset distance along a first preset direction, and the preset distance d refers to the distance between the central axes of the two drive plates 20 extending along a second preset direction, and the value range of the preset distance is 3cm≤d≤5cm; the length l of the pin 41 can be 3cm, which can avoid the pin 41 not penetrating the workpiece to be inserted to a sufficient depth, resulting in a loose connection between the workpiece to be inserted and the needle-punching device; the material of the pin 41 is stainless steel, which can prevent the pin 41 from bending when the workpiece to be inserted is too heavy.

[0031] In this embodiment, as Figure 1 and Figure 2 As shown, the acupuncture device also includes a transmission component 30, which is movably disposed within the housing. Both drive plates 20 are connected to the transmission component 30. One of the drive plates 20 is movably disposed to reciprocate along a second preset direction, thereby driving the transmission component 30 to rotate around a preset axis, so that the transmission component 30 drives the other drive plate 20 to reciprocate along the second preset direction. The two drive plates 20 move in opposite directions along the second preset direction.

[0032] Specifically, the transmission component 30 is used to drive the two drive plates 20, so that when one of the drive plates 20 moves along the second preset direction, the drive plate 20 can drive the transmission component 30 to rotate around the preset axis, so that the transmission component can drive the other drive plate 20 to move along the second preset direction. Since the two drive plates 20 move in opposite directions along the second preset direction, it is ensured that the two drive plates 20 can move towards each other or away from each other, and that the pin 41 can switch smoothly between the first state and the second state.

[0033] In this embodiment, as Figure 1 and Figure 2 As shown, the needle-punching device also includes two transmission columns 31. The transmission component 30 is provided with two strip grooves 32, which are respectively arranged on both sides of the preset axis. The two transmission columns 31 are arranged in a one-to-one correspondence with the two drive plates 20. Each transmission column 31 is arranged on the corresponding drive plate 20, and each transmission column 31 can slide through the corresponding strip groove 32.

[0034] Specifically, since each transmission column 31 is slidably inserted into the corresponding strip groove 32, and the two strip grooves 32 are respectively arranged on both sides of the preset axis, the two strip grooves 32 swing in opposite directions around the preset axis, and the two transmission columns 31 move in opposite directions along the second preset direction.

[0035] In this embodiment, as Figure 1 and Figure 2 As shown, the acupuncture device also includes a first guide member 33, which is disposed inside the housing. The first guide member 33 has two circumferential sidewalls arranged opposite each other along a first preset direction. Each circumferential sidewall is provided with a first groove 34, which extends along a second preset direction. Each drive plate 20 is provided with a first guide portion 22. The two first guide portions 22 and the two first grooves 34 are arranged in a one-to-one correspondence, and each first guide portion 22 cooperates with the corresponding first groove 34.

[0036] Specifically, each first guide portion 22 is movably inserted into the corresponding first slide groove 34, so that the first slide groove 34 can guide the drive plate 20 where the corresponding first guide portion 22 is located, so as to prevent the extension direction of the drive plate 20 from deviating from the second preset direction.

[0037] In this embodiment, as Figure 1 and Figure 2 As shown, the top of the first guide member 33 is provided with a guide post 35, and the middle part of the transmission member 30 is provided with a guide hole 351. The guide post 35 and the guide hole 351 are inserted and connected to connect the transmission member 30 and the first guide member 33.

[0038] Specifically, the transmission component 30 and the first guide component 33 are connected by inserting and connecting the guide post 35 and the guide hole 351. The first guide component 33 is used to support the transmission component 30. The extended line of the axis of the guide post 35 is a preset axis.

[0039] In this embodiment, as Figure 3 and Figure 4 As shown, the housing includes a top plate 11 and four side plates, each extending vertically. The four side plates are connected to the four circumferential sidewalls of the top plate 11. The four side plates include a first side plate, a second side plate, a third side plate 13, and a fourth side plate 14 connected in sequence. The first side plate and the third side plate 13 are arranged opposite each other on both sides of the second side plate along a second preset direction. The second side plate and the fourth side plate 14 are arranged opposite each other on both sides of the first side plate along a first preset direction. A second guide groove 15 is provided on the second side plate, and a third guide groove 16 is provided on the fourth side plate 14. Both the second guide groove 15 and the third guide groove 16 extend along the second preset direction. Each drive plate 20 is provided with a first guide portion 22 and a second guide portion 23 arranged opposite each other along the second preset direction. The second guide groove 15 cooperates with the second guide portion 23 of the drive plate 20 closest to the second side plate, and the third guide groove 16 cooperates with the second guide portion 23 of the drive plate 20 closest to the fourth side plate 14.

[0040] Specifically, the second guide portion 23 of the drive plate 20 closest to the second side plate is movably inserted into the second guide groove 15, so that the second guide groove 15 can guide the drive plate 20 and prevent the movement direction of the drive plate 20 from deviating from the second preset direction; the second guide portion 23 of the drive plate 20 closest to the fourth side plate 14 is movably inserted into the third guide groove 16, so that the third guide groove 16 can guide the drive plate 20 and prevent the movement direction of the drive plate 20 from deviating from the second preset direction; wherein, each drive plate 20 is guided by the first guide portion 22 and the second guide portion 23 thereon, further preventing the movement direction of each drive plate 20 from deviating from the second preset direction.

[0041] In this embodiment, as Figure 5 As shown, the needle-piercing device also includes two needle groups 40, which are arranged one-to-one with two drive plates 20. Each needle group 40 includes multiple needles 41, and each drive plate 20 is provided with multiple through holes 24. The multiple through holes 24 on each drive plate 20 are arranged one-to-one with the multiple needles 41 of the corresponding needle group 40. Each needle 41 passes through the corresponding through hole 24 so that the needles 41 of each needle group 40 are connected to the corresponding drive plate 20. The multiple through holes 24 on each drive plate 20 are arranged in an arc shape, and the center of the arc is located on the side of the drive plate 20 near the transmission member 30.

[0042] Specifically, when the needle-punching device is used to transport sacks or full woven bags, since the upper surface of the sack is arc-shaped, by setting multiple through holes 24 on each drive plate 20 in an arc shape, with the center of the arc located on the side of the drive plate 20 near the transmission component 30, it is possible to avoid inconsistent penetration depth of the needles 41 into the sack at the two sides and the middle of the sack. This prevents uneven force on the sack and ensures a secure connection between the sack and the needles 41, thereby guaranteeing the reliability of the connection between the needle-punching device and the sack to be inserted. Simultaneously, the arc-shaped arrangement of the multiple through holes 24 on each drive plate 20 also increases the distribution area of ​​the needles 41, thereby increasing the force-bearing area of ​​the sack to be inserted.

[0043] In this embodiment, as Figure 2 and Figure 3 As shown, one of the two drive plates 20 is the first drive plate 25, and the other drive plate 20 is the second drive plate 26. The needle-punching device also includes a first drive member 50, a transmission block 51, and a transmission shaft 52. The transmission block 51 is drivenly connected to the first drive member 50. The transmission shaft 52 extends in the vertical direction, and both ends of the transmission shaft 52 are respectively connected to the transmission block 51 and the transmission column 31 on the first drive plate 25, so that the first drive member 50 drives the transmission block 51 to move in a second preset direction, so that the transmission block 51 drives the transmission shaft 52 and the first drive plate 25 to move in the second preset direction.

[0044] Specifically, the transmission block 51 is used to connect the first driving member 50 and the transmission shaft 52. The transmission shaft 52 is used to connect the transmission block 51 and the transmission column 31 on the first driving plate 25, so that the first driving member 50 can drive the transmission column 31 on the first driving plate 25 to move in the second preset direction through the transmission shaft 52 and the transmission block 51, thereby causing the first driving plate 25 to move in the second preset direction, and the first driving plate 25 can drive the second driving plate 26 to move in the second preset direction through the transmission member 30.

[0045] Specifically, the first driving component 50 is a cylinder, and the piston rod of the first driving component 50 extends along a second preset direction.

[0046] In specific implementation, when the first drive plate 25 moves along the second preset direction toward a direction away from the third side plate 13 (e.g. Figure 1When the drive plate 20 moves the transmission column 31 on it along the second preset direction toward the direction away from the third side plate 13, the transmission column 31 pushes the corresponding strip groove 32 to swing counterclockwise around the preset axis, so that another strip groove 32 on the transmission member 30 swings clockwise around the preset axis. The strip groove 32 pushes the corresponding transmission column 31 to move along the second preset direction toward the direction closer to the third side plate 13. The transmission column 31 drives the drive plate 20 to move along the second preset direction toward the direction closer to the third side plate 13.

[0047] In this embodiment, as Figure 3 and Figure 4 As shown, the needle-punching device also includes a second driving member and a transmission disk 54. The second driving member is drivenly connected to the transmission disk 54, and the transmission disk 54 is connected to the top plate 11 of the housing, so that the second driving member drives the housing to move through the transmission disk 54.

[0048] Specifically, the transmission disk 54 is used to connect the housing and the second driving member, so that the second driving member can drive the housing to reciprocate in the vertical direction, ensuring that the pin 41 can switch smoothly between the first state and the second state.

[0049] Specifically, the second driving component is a cylinder, and the piston rod of the cylinder extends in a vertical direction.

[0050] In this embodiment, as Figure 3 and Figure 4 As shown, the needle-punching device also includes a connecting shaft 55. There are multiple connecting shafts 55, which are spaced apart along the circumferential direction of the transmission disk 54. The first end of each connecting shaft 55 is connected to the transmission disk 54, and the second end of each connecting shaft 55 is connected to the top plate 11.

[0051] Specifically, the connecting shaft 55 is used to connect the transmission disk 54 and the top plate 11, so that the transmission disk 54 and the housing can be smoothly connected, thereby ensuring the reliability of the drive connection between the second drive component and the housing.

[0052] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0053] The needle punching device of the present invention includes a housing and two drive plates 20. Each drive plate 20 has a downwardly inclined needle 41 at its bottom. The housing drives the two drive plates 20 to move downward in the vertical direction. At the same time, the two drive plates 20 move towards each other in a second preset direction, so that the needles 41 on each drive plate 20 switch to a first state. Since the two drive plates 20 are arranged at a preset distance along the first preset direction, the needles 41 on the two drive plates 20 in the first state can be prevented from crossing in an X shape. The distance between the insertion holes of the needles 41 on the two drive plates 20 on the workpiece to be inserted is too small. The insertion holes on the workpiece to be inserted are not too dense. Thus, the problem that the needle punching mechanism in the prior art is prone to damage to the fabric when gripping heavy fabrics is solved.

[0054] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0055] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0056] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
