Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Example 1:

[0034] like Figures 2 to 4As shown, a board light painting cutting device includes a left support plate 101 and a right support plate 132. Both the left support plate 101 and the right support plate 132 are rotatably connected to a drive shaft 112. A left cutting shaft 104 is fixedly connected to the drive shaft 112 on the left support plate 101. The left cutting shaft 104 is provided with a first sliding groove. A right cutting shaft 105 is fixedly connected to the drive shaft 112 on the right support plate 132. The right cutting shaft 105 is also slidably connected to the first sliding groove of the left cutting shaft 104. A plurality of left cutting slices 106 are slidably connected to the left cutting shaft 104, and a plurality of right cutting slices 107 are slidably connected to the right cutting shaft 105. The cutting radii of the right cutting slices 107 and the left cutting slices 106 are the same.

[0035] By adjusting the positions of the left cutting slice 106 and the right cutting slice 107 on the left cutting axis 104 and the right cutting axis 105, the light painting on the board can be cut to different sizes. The light painting on the board can be adapted to different sizes by controlling the distance that the right cutting axis 105 slides in the groove of the left cutting axis 104.

[0036] Example 2:

[0037] like Figures 2 to 5 As shown, fixing blocks 108 are fixedly connected to both the left cutting slice 106 and the right cutting slice 107. Fixing bolts 109 are threadedly connected to the fixing blocks 108. Multiple holes are provided on the left cutting shaft 104 and the right cutting shaft 105. A left protective plate 116 is slidably connected to the left support plate 101, and a right protective plate 117 is slidably connected to the right support plate 132. The left protective plate 116 and the right protective plate 117 are slidably connected.

[0038] When the position of the left cutting slice 106 or the right cutting slice 107 needs to be adjusted, push the left protective plate 116 to slide on the left support plate 101, and push the right protective plate 117 to slide on the right support plate 132, thereby exposing the left cutting slice 106 and the right cutting slice 107. Then, move the left cutting slice 106 and the right cutting slice 107 to the appropriate position, manually control the fixing bolt 109 to rotate on the fixing block 108, so that the fixing bolt 109 is inserted into the hole on the left cutting shaft 104 or the right cutting shaft 105, fixing the left cutting slice 106 or the right cutting slice 107 on the left cutting shaft 104 or the right cutting shaft 105, thereby realizing the adjustment of the position of the left cutting slice 106 and the right cutting slice 107, so as to cut the board light painting to different sizes, and avoid the left cutting slice 106 and the right cutting slice 107 from shaking during cutting, which would damage the board light painting.

[0039] After adjusting the position, push the left protective plate 116 and the right protective plate 117 to reset, thereby shielding the left cutting slice 106 and the right cutting slice 107 to avoid external interference and flying debris during cutting.

[0040] Example 3:

[0041] like Figure 2 and Figure 3 As shown, a plurality of left rolling rods 110 are rotatably connected to the left support plate 101, and a plurality of right rolling rods 111 are rotatably connected to the right support plate 132. The right rolling rods 111 are slidably connected to the left rolling rods 110. The plurality of left rolling rods 110 and the plurality of right rolling rods 111 are alternately arranged to form a complete roller shaft. A left bottom plate 102 is fixedly connected to the left support plate 101, and a right bottom plate 103 is fixedly connected to the right support plate 132. The left bottom plate 102 and the right bottom plate 103 are slidably connected.

[0042] During cutting, the illuminated board is placed on a roller consisting of a left roller 110 and a right roller 111, and cutting is performed by pushing the illuminated board to roll on the roller. The left roller 110 and the right roller 111 slide relative to each other to accommodate illuminated board of different sizes.

[0043] By controlling the relative sliding of the left cutting shaft 104 and the right cutting shaft 105, the left base plate 102 and the right base plate 103, and the left rolling rod 110 and the right rolling rod 111, the overall width of the device can be changed, thereby facilitating transportation and storage.

[0044] Example 4:

[0045] like Figure 2 As shown, a first bevel gear 113 is fixedly connected to the drive shaft 112, a motor 115 is fixedly installed on the left support plate 101, and a second bevel gear 114 is fixedly installed on the motor output end 134 of the motor 115. The first bevel gear 113 meshes with the second bevel gear 114. A rotating shaft 133 is provided on the right support plate 132, and a second bevel gear 114 is also fixedly installed on the rotating shaft 133. The second bevel gear 114 meshes with the first bevel gear 113 on the drive shaft 112 on the right support plate 132.

[0046] In use, the motor 115 is started, and the motor 115 drives the second bevel gear 114 to rotate. The first bevel gear 113 and the drive shaft 112 are driven to rotate through the meshing relationship between the first bevel gear 113 and the second bevel gear 114, which in turn drives the left cutting shaft 104 to rotate. The left cutting shaft 104 drives the right cutting shaft 105 to rotate through the slide groove. Thus, the right cutting shaft 105 drives the drive shaft 112 on the right support plate 132 to rotate. In turn, the drive shaft 112 drives the first bevel gear 113, the second bevel gear 114 and the rotating shaft 133 on the right support plate 132 to rotate.

[0047] Example 5:

[0048] like Figure 1 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12 As shown, a connecting rod 118 is fixedly connected to both the left support plate 101 and the right support plate 132. An outer rotating rod 120 is rotatably connected to the connecting rod 118, and an inner drive shaft 119 is rotatably connected to the outer rotating rod 120.

[0049] The motor output end 134 of motor 115 is connected to the inner drive shaft 119 near the left support plate 101 via a transmission component.

[0050] The rotating shaft 133 on the right support plate 132 is connected to the inner drive shaft 119 on the side near the right support plate 132 via a transmission component.

[0051] An outer connecting plate 121 is fixedly connected to the outer rotating rod 120, and a feed roller shaft 122 is rotatably connected to the outer connecting plate 121. A rubber sleeve is provided on the feed roller shaft 122, and the feed roller shaft 122 is connected to the inner drive shaft 119 through a transmission component.

[0052] First, it should be noted that the connecting rod 118, inner drive shaft 119, outer rotating rod 120, outer connecting plate 121, feed roller shaft 122, and two transmission components constitute a set of feed roller follower assemblies. Two sets of feed roller follower assemblies are symmetrically arranged on both sides of the device: one set is mounted on the left support plate 101, and the other set is mounted on the right support plate 132; and the feed roller shafts 122 in both sets are located on the material feeding side. The difference is that the motor 115 is located on the left side of the device and is used to provide power to the feed roller shaft 122 in the feed roller follower assembly mounted on the left support plate 101, causing it to rotate actively. The feed roller follower assembly mounted on the right support plate 132 has no direct power source; instead, the overall device balance is achieved by adding a rotating shaft 133.

[0053] To better illustrate the structure of a set of feed roller follower assemblies, the two transmission components in the set of feed roller follower assemblies are referred to as the first transmission component and the second transmission component, respectively. The connecting rod 118, the outer rotating rod 120, and the outer connecting plate 121 are connected in sequence. The inner drive shaft 119 is rotatably connected in the outer rotating rod 120, and the feed roller shaft 122 is rotatably mounted on the outer connecting plate 121. The inner drive shaft 119 and the feed roller shaft 122 located at both ends of the outer connecting plate 121 are connected by the second transmission component. At the same time, the inner drive shaft 119 is also connected by the first transmission component.

[0054] Furthermore, a set of feed roller follower assemblies mounted on the left support plate 101 has a first transmission component that drives the inner drive shaft 119 to the motor output end 134; a set of feed roller follower assemblies mounted on the right support plate 132 has a first transmission component that drives the inner drive shaft 119 to the rotating shaft 133.

[0055] Secondly, it should be noted that the transmission component can be a synchronous pulley and synchronous belt assembly, a sprocket and chain assembly, or a gear and toothed belt assembly, etc.; the transmission component can also be a belt 135 with key teeth on its inner side, in which case the shaft that is sleeved by the belt 135 to realize the transmission is provided with tooth grooves that cooperate with the key teeth.

[0056] It should also be noted that there are four transmission components in the two sets of feed roller follower assemblies. Theoretically, the specific structures of the four transmission components may not be exactly the same. However, from the perspective of actual equipment production, use, and maintenance, the four transmission components usually adopt the same specific structure, such as using synchronous pulleys and synchronous belt assemblies. Those skilled in the art can choose the specific structure of the transmission components according to the actual situation, which will not be elaborated further.

[0057] In another specific implementation, such as Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, the four transmission components in the two sets of feed roller follower assemblies all use keyed belts 135, which engage with the toothed grooves on the shaft for transmission. The engagement method between the keyed belt 135 and the toothed shaft is as follows: Figure 10 As shown. At this time, the motor output end 134, the rotating shaft 133, the inner drive shaft 119, and the feed roller shaft 122 are each provided with toothed grooves. Furthermore, the upper and lower parts of one inner drive shaft 119 are provided with two toothed grooves, each groove being fitted with a belt 135. More specifically, in one set of feed roller follower assemblies, the inner drive shaft 119 is driven to the motor output end 134 via a belt 135, and in another set of feed roller follower assemblies, the inner drive shaft 119 is driven to the rotating shaft 133 via a belt 135.

[0058] In another specific implementation, such as Figure 11 and Figure 12 As shown, there are four transmission components in the two sets of feed roller follower assemblies, all of which adopt synchronous pulley and synchronous belt assemblies. The setting position of the synchronous pulley in the synchronous pulley and synchronous belt assemblies is the same as the setting position of the tooth groove in the above embodiment, and will not be repeated.

[0059] A torsion spring is provided on the outer rotating rod 120, and the torsion spring is also fixedly connected to the connecting rod 118.

[0060] Figure 7In the state shown, this is the initial state. Before cutting, the outer connecting plate 121 is controlled to rotate counterclockwise around the axis of the outer rotating rod 120, so that the feed roller shaft 122 moves away from the left bottom plate 102 and twists the torsion spring on the outer rotating rod 120. After the board light painting is placed in, the outer connecting plate 121 can be released. The torsion spring on the outer rotating rod 120 drives the outer connecting plate 121 to rotate clockwise, so that the feed roller shaft 122 on the outer connecting plate 121 approaches and contacts the side of the board light painting. The rubber sleeve provides cushioning and increases the friction with the board light painting, thereby avoiding damage to the board light painting and slippage during the cutting of the board light painting.

[0061] In use, the motor 115 is started, and the motor output end 134 of the motor 115 drives the inner drive shaft 119 through the transmission component. The inner drive shaft 119 drives the feed roller shaft 122 through the transmission component, and then the rubber sleeve on the feed roller shaft 122 conveys the plate light painting onto the roller shaft composed of the left rolling rod 110 and the right rolling rod 111, and then cuts it through the left cutting slice 106 and the right cutting slice 107.

[0062] When the feed roller shaft 122 moves to the end of the side of the light painting on the board, the torsion spring on the outer rotating rod 120 drives the outer connecting plate 121 to rotate, so that the feed roller shaft 122 moves to the end face of the light painting on the board, thereby pushing the light painting on the board to continue to move through the torsion spring on the outer rotating rod 120.

[0063] Using this embodiment, the board light painting can be moved by the rotation of the feed roller shaft 122 and the torsion spring on the outer rotating rod 120, thereby facilitating cutting.

[0064] Example 6:

[0065] like Figure 1 and Figure 13 As shown, two sliding rods 123 are fixedly connected to both the left support plate 101 and the right support plate 132. A sliding base plate 124 is slidably connected to the sliding rod 123. A rotating rod 125 is rotatably connected to the sliding base plate 124. An inner connecting plate 127 is fixedly connected to the rotating rod 125. A spring 126 and an upper sliding rod 128 are fixedly connected to the inner connecting plate 127. The upper sliding rod 128 has a hole. The spring 126 is also fixedly connected to the sliding base plate 124. Two limiting rods 129 are fixedly connected to both the left support plate 101 and the right support plate 132. The limiting rod 129 has a groove and a pin. The groove is slidably connected to the upper sliding rod 128. When not in use, the pin on the limiting rod 129 is inserted into the hole of the upper sliding rod 128 to fix the upper sliding rod 128. A threaded rod 130 is threadedly connected to the inner connecting plate 127. A suction cup 131 is fixedly installed on the threaded rod 130.

[0066] This embodiment focuses on describing the cooperation method of components such as the sliding rod 123 and the suction cup 131; therefore, the transmission components, etc., are... Figure 13 Not shown in the image.

[0067] During installation, first remove the pin on the sliding base plate 124 to release the fixation on the upper sliding rod 128. Figure 13 In this state, the spring 126 on the sliding base plate 124 is in a twisted state, so that the spring 126 has a force to drive the inner connecting plate 127 and the rotating rod 125 to rotate clockwise on the sliding base plate 124. Thus, after the upper sliding rod 128 is released from fixation, it pushes the sliding base plate 124 to slide on the sliding rod 123, so that the upper sliding rod 128 slides on the limiting rod 129. The end of the upper sliding rod 128 near the inner connecting plate 127 has a semi-circular structure, and the axis of the semi-circular structure coincides with the axis of the rotating rod 125. The axis of the end of the inner connecting plate 127 near the rotating rod 125 also coincides with the rotating rod 125. When the sliding base plate 124 is about to slide to the limit position on the sliding rod 123, the semi-circular structure of the upper sliding rod 128 is located at the edge of the groove of the limiting rod 129. At this time, The upper sliding rod 128 is no longer restricted by the limiting rod 129, allowing the upper sliding rod 128 and the inner connecting plate 127 to rotate around the axis of the rotating rod 125. Then, under the action of the spring 126, the inner connecting plate 127 drives the rotating rod 125 to rotate clockwise on the sliding base plate 124. Thus, when the semi-circular structure of the upper sliding rod 128 rotates, it will cooperate with the groove of the limiting rod 129. The rotation of the semi-circular structure of the upper sliding rod 128 pushes the limiting rod 129. This thrust acts on the upper sliding rod 128, causing the upper sliding rod 128 and the inner connecting plate 127 to continue moving. This drives the sliding base plate 124 to the limit position on the sliding rod 123. At this time, the upper sliding rod 128 can no longer rotate in the previous direction or slide, and can only rotate in the opposite direction.

[0068] When the inner connecting plate 127 rotates, it drives the threaded rod 130 away from the motor 115. After the inner connecting plate 127 finishes rotating, the threaded rod 130 is manually controlled to rotate on the inner connecting plate 127. The threaded drive suction cup 131 approaches and contacts the ground, thereby fixing the threaded rod 130 to the ground and thus fixing the inner connecting plate 127. At this time, the upper sliding rod 128 slides out of the limit rod 129, and the sliding base plate 124 also moves to the end of the sliding rod 123, so that the sliding base plate 124 can no longer move. Thus, the movement of the left support plate 101 and the right support plate 132 is restricted by the sliding base plates 124 on both sides, thereby fixing the device.

[0069] Using this embodiment, the device can be fixed by the adsorption of multiple suction cups, avoiding shaking during cutting and preventing damage to the light painting on the board.

[0070] 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 or equivalent changes made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
