Description

Technical Field

[0001] This utility model relates to the field of cutting bed technology, specifically to a cutting bed with dual-platform exchange function. Background Technology

[0002] Most existing cutting machines only have one work platform, which cannot meet the production efficiency requirements of mechanized production. Although a few cutting machines have two worktables, these two worktables cannot be interchanged and are usually used for different processes, resulting in limited functionality. Furthermore, the processing on the latter worktable can only be carried out after the processing on the former worktable is completed, leading to low production efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a cutting bed with dual-platform exchange function to solve the technical problems existing in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] Furthermore, the lower inner sides of the left and right sides of the bed are provided with two first linear guide rails, two second linear guide rails, and two sets of contour guide rails. The two first linear guide rails are used to slide with the first working platform. The two second linear guide rails are located outside the two first linear guide rails and are used to slide with the second working platform. The two sets of contour guide rails are located between the two first linear guide rails and the two second linear guide rails. The two sets of contour guide rails are used to cooperate with the first working platform to change the height of the first working platform, so as to avoid collision and interference between the first working platform and the second working platform when the positions of the two working platforms are exchanged.

[0009] Furthermore, two third linear guide rails and two linear racks are respectively provided on the upper part of the outer sides of the left and right sides of the bed. The two third linear guide rails are used to slide with the cutting mechanism, and the two linear racks are used to mesh with the cutting mechanism.

[0010] Furthermore, the platform exchange drive device includes a drive motor, a drive sprocket, a driven sprocket, and a chain. The drive motor is fixedly mounted on the bed, the drive sprocket is fixedly mounted on the output shaft of the drive motor, the driven sprocket is fixedly mounted on the bed, and the drive sprocket and the driven sprocket are connected together by a chain. The lower part of the chain is connected to the rear end of the first working platform, and the upper part of the chain is connected to the rear end of the second working platform.

The lower part of the timing belt is connected to the rear end of the first working platform, and the upper part of the timing belt is connected to the rear end of the second working platform.

[0012] Furthermore, the evacuation device includes a vacuum pump and a liftable air box. The vacuum pump is connected to the liftable air box through an evacuation pipe. The liftable air box is connected to an air box connector located at the bottom of the first or second working platform. The air box connector is connected to an evacuation pipe interface located at the bottom of the first or second working platform through an evacuation pipe.

[0013] Furthermore, the first working platform includes a first platform and a pair of first platform sliding supports, a pair of second platform sliding supports, and multiple pairs of third platform sliding supports symmetrically arranged on the left and right sides of the first platform. The pair of first platform sliding supports and the pair of second platform sliding supports are respectively slidably engaged with the two first linear guide rails and the two sets of contour guide rails. The multiple pairs of third platform sliding supports are respectively slidably engaged with the two first linear guide rails. The pair of third platform sliding supports located at the rear end of the first platform are respectively connected to the lower part of the chain or synchronous belt in the two platform exchange drive devices.

Detailed Implementation

[0041] To make the technical means, creative features, achieved objectives and effects of this utility model readily understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can typically be arranged and designed in various different configurations.

[0042] In the description of the embodiments of this utility model, it should be noted that if terms such as "upper," "lower," "horizontal," or "inner" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use, they are only for the convenience of describing the utility model and simplifying the description, and 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 utility model. Furthermore, terms such as "first" and "second" are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0043] See Figures 1 to 29 This invention illustrates an embodiment of a cutting bed with dual-platform exchange function, comprising a bed body 1, a cutting mechanism 2 slidably disposed on the upper part of the bed body 1, and a first working platform 3 and a second working platform 4 slidably disposed inside the bed body 1. The first working platform 3 and the second working platform 4 can exchange their front and rear positions. Both the first working platform 3 and the second working platform 4 can be used to support and absorb fabric, and both can cooperate with the cutting mechanism 2 to cut the fabric under the action of the cutting mechanism 2.

[0044] Specifically, see Figure 1 In order to facilitate the exchange of positions between the first working platform 3 and the second working platform 4, in the illustrated embodiment, two platform exchange drive devices 5 are provided at the lower end of the interior of the left and right sides of the bed body 1 for driving the first working platform 3 and the second working platform 4 to exchange positions.

[0045] More specifically, see Figures 5 to 7 In the illustrated embodiment, the platform exchange drive device 5 includes a drive motor 501, a drive sprocket 502, a driven sprocket 503, and a chain 504. The drive motor 501 is fixedly mounted on the bed 1, the drive sprocket 502 is fixedly mounted on the output shaft of the drive motor 501, and the driven sprocket 503 is fixedly mounted on the bed 1. The drive sprocket 502 and the driven sprocket 503 are connected together by the chain 504. The lower part of the chain 504 is connected to the rear end of the first working platform 3 via a lower connecting plate B505, and the upper part of the chain 504 is connected to the rear end of the second working platform 4 via an upper connecting plate B506. By connecting the upper and lower parts of the chain 504 to the rear ends of the first working platform 3 and the second working platform 4 respectively, the first working platform 3 and the second working platform 4 can exchange positions under the drive of the chain 504.

[0046] In other embodiments, the platform exchange drive device 5 includes a drive motor 501, a drive pulley, a driven pulley, and a synchronous belt. The drive motor 501 is fixedly mounted on the bed 1, the drive pulley is fixedly mounted on the output shaft of the drive motor 501, the driven pulley is fixedly mounted on the bed 1, and the drive pulley and the driven pulley are connected together by a synchronous belt. The lower part of the synchronous belt is connected to the rear end of the first working platform 3, and the upper part of the synchronous belt is connected to the rear end of the second working platform 4. By connecting the upper and lower parts of the synchronous belt to the rear ends of the first working platform 3 and the second working platform 4 respectively, the first working platform 3 and the second working platform 4 can exchange positions under the drive of the synchronous belt.

[0047] It can be understood here that, in addition to the above-described embodiment which consists of a drive motor 501, a drive sprocket 502, a driven sprocket 503 and a chain 504, or a drive motor 501, a drive pulley, a driven pulley and a timing belt, the platform exchange drive device 5 can also adopt any other structure that can satisfy the corresponding function.

[0048] Specifically, see Figure 1 and Figure 2 In order to ensure the cutting effect of the fabric laid on the first working platform 3 and the second working platform 4, in the illustrated embodiment, a vacuum device 6 is provided at the lower end of the bed body 1 for communicating with the first working platform 3 or the second working platform 4; the vacuum device 6 is used to generate negative pressure on the first working platform 3 or the second working platform 4 to adsorb the fabric laid on the first working platform 3 or the second working platform 4, so as to prevent the fabric from moving or becoming uneven during the cutting process, which would affect the cutting effect.

[0049] More specifically, see Figure 2 and Figure 4In the illustrated embodiment, the evacuation device 6 includes a vacuum pump 601 and a liftable bellows 602. The vacuum pump 601 is connected to the liftable bellows 602 via an evacuation pipe (not shown). The liftable bellows 602 is connected to a bellows connector 12 located at the bottom of the first working platform 3 or the second working platform 4. The bellows connector 12 located at the bottom of the first working platform 3 is connected to an evacuation pipe interface 13 located at the bottom of the first working platform 3 via an evacuation pipe (not shown). The bellows connector 12 located at the bottom of the second working platform 4 is connected to an evacuation pipe interface 13 located at the bottom of the second working platform 4 via an evacuation pipe (not shown). The liftable bellows 602 allows the evacuation device 6 to connect to the bellows connectors 12 located at the bottom of both the first working platform 3 and the second working platform 4; that is, only one evacuation device 6 can simultaneously adapt to both working platforms (i.e., the first working platform 3 and the second working platform 4). During operation, when the first working platform 3 moves above the location of the vacuum device 6, the liftable air box 602 in the vacuum device 6 can be raised and connected to the air box connector 12 provided at the bottom of the first working platform 3; when the second working platform 4 moves above the location of the vacuum device 6, the liftable air box 602 in the vacuum device 6 can be raised and connected to the air box connector 12 provided at the bottom of the second working platform 4; when the first working platform 3 and the second working platform 4 are exchanging positions, the liftable air box 602 in the vacuum device 6 can be lowered to avoid obstructing the position exchange between the first working platform 3 and the second working platform 4.

[0050] Furthermore, in the illustrated embodiments, see [reference]. Figure 20 The liftable bellows 602 includes a bellows body 602a that mates with the bellows connector 12, a bellows slider 602b located on the front side of the bellows body 602a, a bellows seat 602c located on the front side of the bellows body 602a with one end fixedly connected to the bed 1 and the other end slidingly engaged with the bellows slider 602b, and a lifting cylinder 602d fixedly connected to the bellows seat 602c and used to drive the bellows body 602a to rise and fall. The telescopic end of the lifting cylinder 602d is fixedly connected to the bellows body 602a, and the cylinder body of the lifting cylinder 602d is fixedly connected to the bellows seat 602c. Under the action of the lifting cylinder 602d, the bellows body 602a can be driven to rise and fall, thereby achieving communication with the bellows connector 12 located at the bottom of the first working platform 3 or the second working platform 4. Furthermore, the lifting cylinder 602d can be any one of a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder.

[0051] Specifically, see Figure 4 and Figure 5To ensure that the first working platform 3 and the second working platform 4 move linearly along the bed 1, in the illustrated embodiment, two first linear guide rails 7 and two second linear guide rails 8 are respectively provided on the lower inner sides of the left and right sides of the bed 1. The two first linear guide rails 7 are used for sliding engagement with the first working platform 3, and the two second linear guide rails 8 are located outside the two first linear guide rails 7 and are used for sliding engagement with the second working platform 4. Through the sliding engagement of the first linear guide rails 7 and the first working platform 3, and the sliding engagement of the second linear guide rails 8 and the second working platform 4, the linear movement of the first working platform 3 and the second working platform 4 along the bed 1 can be effectively ensured. In addition, by placing the second linear guide rails 8 outside the first linear guide rails 10, the sliding paths of the first working platform 3 and the second working platform 4 can be staggered, avoiding overlap between their sliding paths, which would prevent the first working platform 3 and the second working platform 4 from exchanging positions.

[0052] Specifically, see Figure 4 and Figure 5 To prevent collisions and interference between the first working platform 3 and the second working platform 4 during the exchange of positions, in the illustrated embodiment, two sets of contour guide rails 9 are provided on the lower inner sides of the left and right sides of the bed body 1. The two sets of contour guide rails 9 are located between two first linear guide rails 7 and two second linear guide rails 8. The two sets of contour guide rails 9 are used to slide with the first working platform 3 to change the height of the first working platform 3, so as to avoid collisions and interference between the first working platform 3 and the second working platform 4 when the first working platform 3 exchanges positions with the second working platform 4.

[0053] More specifically, see Figure 21 In the illustrated embodiment, each set of contour guide rails 9 includes two parallel, opposite, and partially offset contour tracks 901. Each contour track 901 consists of a straight track 901a and two trapezoidal tracks 901b disposed at both ends of the straight track 901a. The straight track 901a is used to lower the platform surface of the first work platform 3; the trapezoidal tracks 901b are used to raise the platform surface of the first work platform 3. (See also...) Figures 22 to 29 When the first working platform 3 travels to the straight track 901a of the contouring track 901, the platform of the first working platform 3 will descend and become lower than the platform of the second working platform 4, which facilitates the exchange of positions with the second working platform 4 (that is, the first working platform 3 and the second working platform 4 are at different heights at this time, which facilitates the exchange of positions between the two); when the first working platform 3 travels to the trapezoidal track 901b of the contouring track 901, the platform of the first working platform 3 will rise and become flush with the platform of the second working platform 4, which facilitates the cooperation with the cutting mechanism 2 to cut the fabric.

[0054] Specifically, see Figure 3In order to facilitate the sliding of the cutting mechanism 2 on the bed 1, in the embodiment shown, two third linear guide rails 10 and two linear racks 11 are respectively provided on the upper part of the outer side of the left and right sides of the bed 1. The two third linear guide rails 10 are used to slide with the cutting mechanism 2, and the two linear racks 11 are used to mesh with the cutting mechanism 2.

[0055] Specifically, in this utility model, the cutting mechanism 2 adopts existing technology, namely, a common cutting mechanism used on existing ordinary cutting beds, see [reference]. Figure 9 and Figure 10 It typically consists of a gantry frame 201, a cutting head 202 slidably mounted on the crossbeam of the gantry frame 201, an eighth slider 203 mounted on the column of the gantry frame 201 and slidably engaged with the third linear guide rail 10, and a moving motor 204 meshing with the linear rack 11; wherein, the output end of the moving motor 204 is provided with a gear 205, and the moving motor 204 meshes with the linear rack 11 through the gear 205. Furthermore, the number of cutting mechanisms 2 can be one or more; the cutting head 202 can be a laser cutting head or an electric blade cutting head.

[0056] Specifically, in the illustrated embodiments, see [reference]. Figure 11 and Figure 12 The first working platform 3 includes a first platform 301 and a pair of first platform sliding support legs 302, a pair of second platform sliding support legs 303, and multiple pairs of third platform sliding support legs 304 symmetrically arranged on the left and right sides of the first platform 301. The pair of first platform sliding support legs 302 and the pair of second platform sliding support legs 303 are respectively slidably engaged with two first linear guide rails 7 and two sets of contour guide rails 9. The multiple pairs of third platform sliding support legs 304 are respectively slidably engaged with two first linear guide rails 7. The pair of third platform sliding support legs 304 located at the rear end of the first platform 301 are respectively connected to the lower part of the chain 504 or synchronous belt in the two platform exchange drive devices 5.

[0057] More specifically, in the illustrated embodiments, see [reference]. Figure 13 Each of the pair of third platform sliding support legs 304 located at the rear end of the first platform 301 is provided with a lower connecting plate A305 for connecting to the lower part of the chain 504 or timing belt. The lower connecting plate 305 facilitates the connection of the first working platform 3 to the chain 504 or timing belt in the platform exchange drive device 5, enabling the first working platform 3 to move during the movement of the chain 504 or timing belt. Furthermore, the lower connecting plate A305 is connected to a corresponding lower connecting plate B505 located at the lower part of the chain 504 or timing belt.

The distance between the two contoured tracks 901 contained in each set of contoured guide rails 9 is L2, and L2=L1; that is, the distance between the first platform sliding support 302 and the second platform sliding support 303 is equal to the distance between the two contoured tracks 901 contained in the contoured guide rails 9. During operation, the first platform sliding support 302 and the second platform sliding support 303 of the first working platform 3 respectively slide in cooperation with two contoured tracks 901 in each set of contoured guide rails 9, that is, the first platform sliding support 302 and the second platform sliding support 303 each slide along one contoured track 901; when the first platform sliding support 302 and the second platform sliding support 303 travel to the trapezoidal track 901b of the contoured track 901, the platform surface of the first platform 301 of the first working platform 3 will rise to the same height as the platform surface of the second platform 401 of the second working platform 4; when the first platform sliding support 302 and the second platform sliding support 303 travel to the straight track 901a of the contoured track 901, the platform surface of the first platform 301 of the first working platform 3 will descend to a height lower than the platform surface of the second platform 401 of the second working platform 4. (See reference...) Figures 22 to 29 .

[0069] Specifically, see Figure 8 To prevent collision damage between the first working platform 3 and the second working platform 4 and the bed body 1, and to ensure accurate positioning of the first working platform 3 and the second working platform 4, rubber anti-collision blocks 14 and limit sensors 15 are installed at both the front and rear ends of the bed body 1. The rubber anti-collision blocks 14 prevent collision damage between the first working platform 3 and the second working platform 4 and the bed body 1. The limit sensors 15 ensure accurate positioning of the first working platform 3 and the second working platform 4.

[0070] Specifically, in the illustrated embodiment, the bottom of the bed body 1 is also provided with a plurality of fifth support legs 17.

[0071] It should be noted that the cutting bed with dual-platform exchange function provided by this utility model also includes a controller, which is used to control the operation of the entire cutting bed. Since the controller is prior art, it will not be described in detail in this application.

[0072] Figures 22 to 29 The exchange process between the first working platform 3 and the second working platform 4 is illustrated; wherein, Figure 22 and Figure 23 The diagram shows the state before the first working platform 3 and the second working platform 4 are swapped; Figure 24 and Figure 25 This shows the state when the back end of the first working platform 3 meets the front end of the second working platform 4; Figure 26 and Figure 27 This shows the state when the front end of the first working platform 3 meets the back end of the second working platform 4; Figure 28 and Figure 29 The diagram shows the state after the first working platform 3 and the second working platform 4 have been exchanged.

[0073] The working principle of a cutting bed with dual-platform exchange function provided in this embodiment of the utility model is as follows:

[0074] In use, the fabric to be cut is first laid on the first working platform 3, and then the first working platform 3 and the second working platform 4 are swapped in the first round. After the first round of swapping is completed, the cutting mechanism 2 is started to cut the fabric to be cut on the first working platform 3. At the same time, the fabric to be cut is laid on the second working platform 4.

[0075] After the fabric to be cut on the first working platform 3 is cut (at this time, the second working platform 4 has also finished laying the material), the first working platform 3 and the second working platform 4 are swapped for the second time. Then the cut fabric on the first working platform 3 is removed. Then the cutting mechanism 2 is started to cut the fabric to be cut on the second working platform 4. At the same time, the fabric to be cut is laid on the first working platform 3.

[0076] After the fabric to be cut on the second working platform 4 is cut, the first working platform 3 and the second working platform 4 are swapped for the third time. Then the cut fabric on the second working platform 4 is removed. Then the cutting mechanism 2 is started to cut the fabric to be cut on the first working platform 3. At the same time, the fabric to be cut is laid on the second working platform 4.

[0077] After the fabric to be cut on the first working platform 3 is cut again, the first working platform 3 and the second working platform 4 are swapped for the fourth time. Then the cut fabric on the first working platform 3 is removed. Then the cutting mechanism 2 is started to cut the fabric to be cut on the second working platform 4. At the same time, the fabric to be cut is laid on the first working platform 3.

[0078] After the fabric to be cut on the second working platform 4 is cut, the first working platform 3 and the second working platform 4 are swapped for the fifth time. Then the cut fabric on the second working platform 4 is removed. Then the cutting mechanism 2 is started to cut the fabric to be cut on the first working platform 3. At the same time, the fabric to be cut is laid on the second working platform 4.

[0079] By continuously repeating the above-mentioned position swapping, material laying, and cutting operations between the first working platform 3 and the second working platform 4, the cutting bed with dual-platform exchange function provided by this utility model can achieve the cyclical operation of the two working platforms continuously swapping positions, continuously alternating material laying, and continuously alternating cutting processes.

[0080] Finally, it should be noted that the above description is only an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
