Description

Technical Field

[0001] This invention belongs to the field of cutting bed technology, specifically, it relates to a clamping device for a cutting bed. Background Technology

[0002] In the garment making process, the fabric needs to be cut according to the preset pattern. This is when a cutting table is used. In order to improve cutting efficiency, a certain thickness of fabric is often laid on the cutting table before cutting. During the cutting process, clamping devices on both sides of the cutting table will clamp the fabric to prevent it from shifting.

[0003] To ensure the stability of the clamping, the number of fabric layers is controlled during fabric laying to avoid insufficient clamping force on the fabric in the middle of the clamping device when the thickness is too thick. This is especially true for fabrics with smooth surfaces, such as silk, which require fewer layers. Because of the fewer layers, multiple cuts are required, resulting in low cutting efficiency. Therefore, improvements are needed. Summary of the Invention

[0004] To address the aforementioned problems in the prior art, the present invention provides a clamping device for a cutting bed, which is suitable for situations where the fabric has more layers due to its layered clamping capability.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] As one aspect of the present invention, a clamping device for a cutting bed is provided, comprising: a telescopic rotating part, a support plate, and a connecting rod located above the support plate; the connecting rod is connected to the telescopic rotating part, and the connecting rod extends and retracts and / or rotates relative to the cutting bed through the telescopic rotating part; the connecting rod is provided with a first clamping plate and a second clamping plate at a predetermined interval in the circumferential direction, and the structure of the first clamping plate and the structure of the second clamping plate are the same;

[0007] It also includes two or more pressure plates arranged in sequence above the pallet, each pressure plate having a through hole for the first or second pallet to pass through, with adjacent through holes arranged at an angle to each other on the same projection plane.

[0008] Each pressure plate is inserted into the connecting rod through its through hole. The pressure plates are set at a preset distance. The pressure plate at the bottom is defined as the first pressure plate, and the other pressure plates are defined as the second pressure plate, the third pressure plate, and so on. The through hole on the first pressure plate is defined as the first through hole, the through hole on the second pressure plate is defined as the second through hole, and so on.

[0009] In the initial state, the first pressure plate is located between the first and second clamping plates, and all other pressure plates are located on the second clamping plate. The first clamping plate cannot pass through the first through hole on the first pressure plate, while the second clamping plate can pass through the second through hole on the second pressure plate. When the connecting rod rotates to a preset angle, the first clamping plate can pass through the first through hole on the first pressure plate, while the second clamping plate cannot pass through the second through hole on the second pressure plate. At this time, the connecting rod moves upward under the action of the telescopic power unit, and the first clamping plate passes through the first through hole on the first pressure plate. The first clamping plate separates from the first pressure plate and becomes the clamping plate of the second pressure plate, and so on.

[0010] Optionally, the telescopic rotating part includes a telescopic power part, the output end of which is connected to a first connecting member, the other end of which is connected to a rotating power part, and the output end of the rotating power part is connected to a connecting rod through a second connecting member.

[0011] Alternatively, the upper through-hole can be rotated around its center at the included angle to coincide with the lower through-hole.

[0012] Alternatively, the shape of the second through hole is obtained by rotating the shape of the first through hole by 90 degrees around its center.

[0013] Optionally, the plate also includes a limiting member for limiting the pressure plate, the limiting member cooperating with a limiting hole on the pressure plate, the limiting member being disposed on the side of the pressure plate, and the side of the pressure plate having a limiting hole that cooperates with the limiting member.

[0014] Optionally, it also includes a side pressing member, which is slidably connected to each pressing plate. The pressing plate is provided with a longitudinally arranged track, and the side pressing member is slidably connected to the track. The side pressing member presses the fabric in the two adjacent pressing plates above into the fabric in the two adjacent pressing plates above, so as to avoid the fabric in the two adjacent pressing plates above having downward deformation space during the cutting process.

[0015] Optionally, the tray is provided with a notch for the passage of the first pallet.

[0016] Alternatively, both the first and second card plates are made of the same cuboid and extend in the same direction.

[0017] Alternatively, both the first through hole and the second through hole can be rectangular.

[0018] The advantages of the cutting bed clamping device of the present invention are specifically reflected in the following aspects: by using a multi-layer clamping method, the problem of insufficient force on the middle fabric is avoided, making the thickness of the fabric to be cut thicker than that of conventional clamping devices; by the mutual cooperation of the first clamping plate, the second clamping plate on the connecting rod and the through hole shape on each pressure plate, a simple structure can achieve multi-layer stable clamping, which increases the thickness that can be laid during fabric cutting, improves cutting efficiency, and the device has a simple driving process, high integration, and small size.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0031] One embodiment of this application provides a clamping device for a cutting bed, such as... Figures 1-5 and Figure 9 As shown, it includes: a telescopic rotating part, a support plate 1 that cooperates with the cutting worktable of the cutting bed, and a connecting rod 4 located above the support plate 1; the connecting rod 4 is connected to the telescopic rotating part, and the connecting rod 4 extends and retracts and / or rotates relative to the cutting bed through the telescopic rotating part; the telescopic rotating part includes a telescopic power part 43, which is a telescopic cylinder or a telescopic hydraulic cylinder, which is prior art and will not be described in detail. The output end of the telescopic power part 43 is connected to a first connecting member 44, and the other end of the first connecting member 44 is connected to a rotating power part 45, which is a rotary motor, which is prior art and will not be described in detail; the output end of the rotating power part 45 is connected to the connecting rod 4 through a second connecting member 46, which drives the connecting rod 4 to rotate, and the telescopic power part 43 drives the rotating power part 45 to extend and retract, realizing the telescopic movement of the connecting rod 4 relative to the cutting bed.

[0032] As specifically illustrated, in this embodiment, the connecting rod 4 is provided with a first locking plate 41 and a second locking plate 42 at a preset interval in the circumferential direction. The structure of the first locking plate 41 and the structure of the second locking plate 42 are the same. When the connecting rod 4 is extended and / or rotated, the first locking plate 41 and the second locking plate 42 also extend and / or rotate accordingly.

[0033] Furthermore, in this embodiment, two or more pressure plates are arranged sequentially above the pallet 1. Each pressure plate has a through hole for the first clamping plate 41 or the second clamping plate 42 to pass through. Adjacent through holes are set at an angle to each other on the same projection plane. The upper through hole rotates around its center as a fulcrum and then coincides with the lower through hole. The rotation direction can be clockwise or counterclockwise, depending on the actual needs. This is existing technology and will not be elaborated further. For ease of processing and operation, adjacent through holes are set vertically, that is, the upper through hole rotates 90 degrees around its center as a fulcrum and then coincides with the lower through hole. It should be noted that the pressure plate can move up and down relative to the cutting bed. The pressure plate and the cutting bed are slidably connected or non-contactly connected through the cooperation of a slide rail and a sliding block, depending on the actual needs. The number of pressure plates is set as needed, and the through holes between adjacent pressure plates are in opposite directions.

[0034] like Figures 1-5 As shown, in the initial state, each pressure plate is inserted into the connecting rod 4 through its through hole. The pressure plates are set at a preset distance. The pressure plate at the bottom is defined as the first pressure plate 2, and the other pressure plates are defined as the second pressure plate 3, the third pressure plate, etc., in sequence. The through hole on the first pressure plate 2 is defined as the first through hole 21, the through hole on the second pressure plate 3 is defined as the second through hole 31, and so on.

[0035] The first pressure plate 2 is located between the first clamping plate 41 and the second clamping plate 42, and the other pressure plates are all located on the second clamping plate 42. The first clamping plate 41 cannot pass through the first through hole 21 on the first pressure plate 2, while the second clamping plate 42 can pass through the second through hole 31 on the second pressure plate 3. When the connecting rod 4 rotates to a preset angle, the first clamping plate 41 can pass through the first through hole 21 on the first pressure plate 2, while the second clamping plate 42 cannot pass through the second through hole 31 on the second pressure plate 3. At this time, the connecting rod 4 moves upward under the action of the telescopic power unit 43, and the first clamping plate 41 passes through the first through hole 21 on the first pressure plate 2. The first clamping plate 41 separates from the first pressure plate 2 and serves as the clamping plate of the second pressure plate 2, and so on.

[0036] As an example, such as Figures 1-6 As shown, the first card plate 41 and the second card plate 42 are both made of two identical cuboids and the extension directions of the first card plate 41 and the second card plate 42 are the same; the first through hole 21 and the second through hole 31 are both rectangular and the shape of the second through hole 31 is obtained by rotating the shape of the first through hole 21 by 90 degrees around its center.

[0037] As further explained, in this embodiment, such as Figure 5 As shown, it also includes limiting members 5 for limiting the pressure plate. The number of limiting members 5 is the same as the number of pressure plates, and they are used to limit the pressure plate to a preset position. Specifically, the limiting members 5 cooperate with the limiting holes on the pressure plate. As an example, the limiting members 5 are provided on the side of the pressure plate, and the side of the pressure plate has a limiting hole that cooperates with the limiting members 5. The limiting plate 5 is controlled to extend and retract horizontally by a telescopic motor. When the pressure plate needs to be limited at the preset position, the telescopic motor controls the limiting plate 5 to extend and cooperate with the limiting hole on the pressure plate, thereby limiting the pressure plate at that position and putting the pressure plate into working state.

[0038] As further explained, in this embodiment, such as Figure 8As shown, it also includes a side pressing member 8, which is slidably connected to each pressing plate. The pressing plate is provided with a longitudinally arranged track 7, and the side pressing member 8 is slidably connected to the track 7. The side pressing member 8 presses the fabric 9 in the two adjacent pressing plates above to the fabric 9 in the two adjacent pressing plates above, so as to avoid the fabric 9 in the two adjacent pressing plates above having a certain downward deformation space during the cutting process, which would affect the cutting operation.

[0039] It should be noted that, for example Figure 7 As shown, the fabric 9 between two adjacent pressure plates is separated by a distance equal to the thickness of the pressure plate. To reduce this distance, the thickness of the pressure plate should be as thin as possible.

[0040] As further explained, in this embodiment, such as Figures 1-6 As shown, the tray 1 is provided with a notch 11 for the first clamping plate 41 to pass through, so as to avoid obstructing the up and down movement of the first clamping plate 41; since the lowest position of the first clamping plate 41 is optimal: the upper surface of the first clamping plate 41 is lower than or flush with the upper surface of the tray 1, so that the clamping device can also be used when the number of fabric layers is reduced.

[0041] It should be noted that the orientation and shape of the through holes and the clamping plate can be changed, as long as the clamping plate as mentioned in the preceding section is satisfied. Figures 1-4 In any state, it is acceptable whether each card can pass through the corresponding through hole.

[0042] Operation process: In the initial state, such as Figure 1 As shown, the first clamping plate 41 is between the first pressure plate 2 and the support plate 1, and the second clamping plate 42 is between the first pressure plate 2 and the second pressure plate 3. During the extension and retraction of the connecting rod 4, the first pressure plate 2 can be moved up and down. At this time, the fabric 9 is laid between the support plate 1 and the first pressure plate 2. When the laying thickness does not require the use of the second pressure plate 3, the first pressure plate 2 is pressed down by the second clamping plate 42, and the fabric 9 is pressed down by the first pressure plate 2 to achieve clamping and fixing.

[0043] When the thickness of the fabric 9 needs to be increased, thus utilizing the space between the first pressure plate 2 and the second pressure plate 3, the fabric 9 between the support plate 1 and the first pressure plate 2 is first laid to the set maximum height. Then, the connecting rod 4 retracts. During the retraction process, such as... Figure 2 As shown, the second clamping plate 42 passes through the second through hole 31 on the second pressure plate 3 to reach above the second pressure plate 3. At this time, the first clamping plate 41 is still located below the first pressure plate 2. Then, the connecting rod 4 is rotated 90 degrees to obtain the following result. Figure 3 As shown, the connecting rod 4 retracts to obtain the state shown. Figure 4 In the indicated state, the first pressure plate 41 is located between the first pressure plate 2 and the second pressure plate 3, with the first pressure plate 2 pressing down on the first layer of fabric 9; due to the Figure 4In terms of state, the first clamping plate 41 cannot pass through the second through hole 31, so the first clamping plate 41 can lift the second pressure plate 3, change the distance between the second pressure plate 3 and the first pressure plate 2, so as to facilitate the laying of the second layer of fabric 9 with different numbers of layers. After the second layer of fabric 9 is laid, the second clamping plate 42 is pressed down. At this time, the second clamping plate 42 cannot pass through the second through hole 31, so the second clamping plate 42 can apply downward pressure to the second pressure plate 3 so that the second pressure plate 3 can press the second layer of fabric 9 tightly.

[0044] Furthermore, before the second layer of fabric 9 is laid, that is, before the device is in the... Figure 1 In the specified state, the limiting plate 5 on the left side of the first pressure plate 2 extends into the limiting hole on the side of the first pressure plate 2 to prevent the device from being in the specified state. Figure 1 Towards Figure 2 During the change, the pressure on the fabric 9 between the first pressure plate 2 and the support plate 1 disappears; the limiting plate 5 references... Figure 5 As shown, the limit plate 5 can be horizontally extended and retracted by a telescopic motor.

[0045] It should be noted that all of the above components can be integrated and assembled through a proprietary clamping device housing, or they can be directly mounted on the housing of the cutting table.

[0046] It should be noted that the orientations of the first through hole 21, the second through hole 31, the first clamping plate 41, and the second clamping plate 42 are not only... Figures 1-5 One method is to ensure that the centers of the first through hole 21 and the second through hole 31 are rotated 90 degrees, and the first clamping plate 41 and the second clamping plate 42 are aligned with the second through hole 31.

[0047] like Figure 6 As shown, when the clamping device has three pressure plates: the first pressure plate 2, the second pressure plate 3 and the third pressure plate 6, the third through hole 61 on the third pressure plate 6 is consistent with the first through hole 21. When it is necessary to lay the fabric 9 between the second pressure plate 3 and the third pressure plate 6, the operation can be referred to the laying of the first pressure plate 2 and the second pressure plate 3, and will not be described again.

[0048] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0049] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this application. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0050] In the description of this application, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this application; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0051] 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.

[0052] 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.

[0053] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0054] The above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made within the scope of the claims of the present invention should be included in the scope of the present invention.
