Description

Technical Field

[0001] The present invention relates to the field of building technology, and in particular, to an adjustable edge cutting device for a compact shelf. Background Art

[0002] Compact shelves can be used for the storage of books in libraries and files in various enterprises. Compared with traditional bookshelves, shelves, and filing racks, compact shelves have a larger storage capacity and are more systematic. When installing a compact shelf, it is necessary to adjust the length of the compact shelf according to the indoor situation. Since the length of the compact shelf is fixed after production, if the compact shelf is too long, it is necessary to cut the compact shelf so that the length of the compact shelf can fit the installation location during installation. Currently, when cutting a compact shelf, a cutting device is manually held to cut the compact shelf. Since the compact shelf is relatively high, if the compact shelf is cut manually with the aid of a cutting device, it is necessary to climb to a high place with the aid of a climbing device and then cut the compact shelf. In this way, the working risk is relatively high.

[0003] Therefore, it is necessary to develop an adjustable edge cutting device for a compact shelf that can automatically cut the compact shelf by adjusting the height. Summary of the Invention

[0004] In order to overcome the drawback that when cutting a compact shelf currently, it is necessary for a person to climb to a high place to cut the compact shelf, which is relatively dangerous, and in view of the deficiencies of the prior art, the present invention provides an adjustable edge cutting device for a compact shelf that can automatically cut the compact shelf by adjusting the height.

[0005] To achieve the above object, the present invention is realized through the following solutions: An adjustable edge cutting device for a compact shelf includes a housing, a guide rod, a first slide rail, a slide rod, a servo motor, a motor bracket, a rotating shaft, and a cutting blade. A guide rod is connected to the housing, a first slide rail is slidably connected to the guide rod, a slide rod is slidably connected to the upper side of the first slide rail, a motor bracket is connected to the slide rod, a servo motor is connected to the motor bracket, a rotating shaft is rotatably connected to the middle of the slide rod, the rotating shaft is connected to the output shaft of the servo motor, and a cutting blade is connected to the rotating shaft. It further includes a rotating door, a hinge, an adjusting mechanism, and a moving mechanism. A rotating door is rotatably connected to the front right side of the housing through a hinge. An adjusting mechanism for adjusting the height of the cutting blade is connected between the upper part of the first slide rail and the slide rod. A moving mechanism for driving the cutting blade to move is connected between the housing, the motor bracket, and the rotating shaft. By starting the servo motor, the components of the moving mechanism drive the cutting blade to automatically move back and forth to cut the compact shelf.

[0006] As a preferred technical solution of the present invention, the adjusting mechanism includes a first limiting rod and a first spring. Chutes are opened on both the front and rear sides of the right part of the sliding rod. The first limiting rods for limiting the sliding rod are slidably connected inside the chutes. Limiting grooves are opened on the right sides of the first slide rails. The first limiting rods are all slid inside the limiting grooves on the same side. First springs are connected between the front sides of the front first limiting rods and the rear sides of the rear first limiting rods and the sliding rod. By the up and down movement of the first limiting rods in cooperation with the limiting grooves, the sliding rod is limited, and thus the height of the cutting blade is adjusted.

Second springs for supporting the first toothed rod are connected between the bottoms of the second slide rails and the bottom of the first toothed rod. The bottom of the motor bracket is connected with an L-shaped fixing rod. The first gear is rotatably connected to the lower left side of the L-shaped fixing rod. The first gear meshes with the first toothed rod. The second gear is connected to the right side of the rotating shaft. The second gear meshes with the first gear. By the meshing transmission of the first gear and the first toothed rod, the cutting blade is driven to move back and forth automatically to cut the compact rack.

[0008] As a preferred technical solution of the present invention, a pulling mechanism for controlling the first limiting rods to move outward simultaneously is further included. The pulling mechanism includes an n-shaped fixing rod, a first pulling rope, a first guiding wheel, and a first wire winder. The n-shaped fixing rod is connected to the right side of the sliding rod.

The first guiding wheels are rotatably connected to both the front and rear sides of the right wall of the n-shaped fixing rod. The first wire winder is rotatably connected to the middle of the right side of the n-shaped fixing rod. The first pulling ropes for driving the first limiting rods to move outward simultaneously are connected to both the front and rear sides of the first wire winder. The front first pulling rope bypasses the front first guiding wheel and is connected to the front first limiting rod. The rear first pulling rope bypasses the rear first guiding wheel and is connected to the rear first limiting rod. By rotating the first wire winder to wind up the first pulling ropes, the first limiting rods are driven to move away from each other simultaneously.

[0009] As a preferred technical solution of the present invention, it further includes a limit fixing mechanism for supporting the first tooth bar. The limit fixing mechanism includes a fixing ring, a second limit rod and a third spring. Fixing rings are vertically and evenly spaced and connected to the right part of the opposite sides of the second slide rail. Second limit rods for supporting the first tooth bar are slidably connected in the fixing rings. The first tooth bar contacts the second limit rods. Third springs are sleeved on the right sides of the second limit rods. Two ends of the third spring are respectively connected to the second limit rod and the fixing ring. By pulling the second limit rod to no longer limit the first tooth bar, the first tooth bar moves up and down with the first gear to adjust the position. After the adjustment is completed, the second limit rod moves leftward to reset and support the first tooth bar.

[0010] As a preferred technical solution of the present invention, it further includes a winding mechanism for automatically limiting the first tooth bar. The winding mechanism includes a second tooth bar, a third gear, a fixed shaft, a second wire winder, a second pulling rope, a second guide wheel, a connecting rod, a support rod and a fourth spring. Support rods are slidably connected to the front and rear sides of the n-shaped fixed rod. A second tooth bar is connected between the upper parts of the support rods. The top of the second tooth bar contacts the outer shell. Fourth springs are sleeved on the lower parts of the support rods. Two ends of the fourth spring are respectively connected to the n-shaped fixed rod and the support rod. A fixed shaft is rotatably connected to the right front side of the upper part inside the outer shell. A third gear is connected to the left side of the fixed shaft. The third gear meshes with the second tooth bar. A second wire winder is connected to the left side of the fixed shaft. The second wire winder is located on the left side of the third gear. Second pulling ropes are connected to the front and rear sides of the second wire winder. Connecting rods are connected between the right sides of the front second limit rods. Connecting rods are connected between the right sides of the rear second limit rods. A group of second guide wheels are connected to the front and rear inner walls of the outer shell. One end of the front second pulling rope bypasses the front group of second guide wheels and is connected to the right side of the front connecting rod. One end of the rear second pulling rope bypasses the rear group of second guide wheels and is connected to the right side of the rear connecting rod. By rotating the second wire winder to wind and relax the second pulling rope, and at the same time under the reset action of the third spring, the second limit rod is driven to automatically move leftward to limit the first tooth bar.

[0011] As a preferred technical solution of the present invention, it further includes a clamping mechanism for clamping the compact rack. The clamping mechanism includes a cylinder, a support plate, a screw rod and a clamping plate. Cylinders are fixedly connected to the front and rear sides of the left part of the outer shell through bolts. Support plates are connected to the inner sides of the telescopic rods of the cylinders. Screw rods are threadedly connected to the upper parts of the support plates. Clamping plates for improving the stability during the cutting of the compact rack are rotatably connected to the bottoms of the screw rods.

[0012] As a preferred technical solution of the present invention, a handle is connected to the right front side of the revolving door.

[0013] The present invention has at least one of the following advantages: By adjusting the height of the cutting blade, the present invention can cut the dense rack at any height, and driven by the meshing transmission of the first toothed rod and the first gear, the cutting blade is driven to move back and forth to automatically cut the dense rack. In this way, the working efficiency is relatively high; Through the meshing transmission of the first toothed rod and the first gear, the cutting blade can move back and forth by itself to cut the dense rack, without manual control by the staff, and the operation is simple; By winding and relaxing the first pulling rope by the first wire winder, and at the same time with the cooperation of the first spring, the first limiting rod can move by itself, without manually moving each first limiting rod one by one, which is troublesome; By winding and relaxing the second pulling rope by the second wire winder, and at the same time with the cooperation of the third spring, the second limiting rod can automatically support the first toothed rod, which can reduce the gravity of the second spring and improve the service life of the device; By clamping the dense rack, the stability during cutting of the dense rack can be improved.

Detailed implementation manners

[0031] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but it is not limited to the present invention.

[0032] Embodiment 1

[0033] An adjustable edge cutting device for a compact shelf, as Figures 1 - 9As shown in the figure, it includes a housing 1, a guide rod 2, a first slide rail 3, a slide bar 4, a servo motor 5, a motor bracket 51, a rotating shaft 6, a cutting blade 7, a rotating door 71, a hinge 72, an adjusting mechanism 8 and a moving mechanism 9. A guide rod 2 is welded to the lower right side inside the housing 1. Two first slide rails 3 are slidably connected to the front side of the guide rod 2. A slide bar 4 is slidably connected between the upper sides of the two first slide rails 3. A motor bracket 51 is welded to the right side of the slide bar 4. A servo motor 5 is fixedly connected to the inside of the motor bracket 51 by bolts. The middle part of the slide bar 4 is rotatably connected to a rotating shaft 6. The right side of the rotating shaft 6 is connected to the output shaft of the servo motor 5 through a coupling. The left side of the rotating shaft 6 is connected to a cutting blade 7. A rotating door 71 is rotatably connected to the right front side of the housing 1 through two hinges 72. A handle is connected to the right front side of the rotating door 71. An adjusting mechanism 8 is connected between the upper parts of the two first slide rails 3 and the slide bar 4. A moving mechanism 9 is connected between the housing 1, the motor bracket 51 and the rotating shaft 6. The adjusting mechanism 8 includes a first limiting rod 81 and a first spring 83. Chutes 84 are opened on the front and rear sides of the right part of the slide bar 4. Two first limiting rods 81 are slidably connected to the inside of the two chutes 84. Limiting grooves 82 are opened on the right sides of the two first slide rails 3. The first limiting rods 81 are all slidably located inside the limiting grooves 82 on the same side. A first spring 83 is connected between the front side of the front first limiting rod 81 and the rear side of the rear first limiting rod 81 and the slide bar 4. The moving mechanism 9 includes a second slide rail 91, a second spring 92, a first rack 93, a first gear 94, an L-shaped fixing rod 95 and a second gear 96. Second slide rails 91 are symmetrically welded to the front and rear sides of the lower right side inside the housing 1. A first rack 93 is slidably connected between the upper parts inside the two second slide rails 91. A second spring 92 is connected between the bottom of the two second slide rails 91 and the bottom of the first rack 93. An L-shaped fixing rod 95 is welded to the bottom of the motor bracket 51. A first gear 94 is rotatably connected to the lower left side of the L-shaped fixing rod 95. The first gear 94 meshes with the first rack 93. A second gear 96 is connected to the right side of the rotating shaft 6 by a key. The second gear 96 meshes with the first gear 94.

[0034] During use, first place the compact shelving on the left side of the outer shell 1 so that the edge of the compact shelving contacts the cutting blade 7. Then, the staff adjusts the position of the cutting blade 7 according to the position to be cut. First, grasp the handle to open the rotating door 71, and then manually move the first limiting rod 81 outward to disengage from the sub-groove of the limiting groove 82. At this time, the first spring 83 is compressed. Then, move the sliding rod 4, the servo motor 5, the motor bracket 51, the rotating shaft 6, and the cutting blade 7 up and down. After adjusting to the appropriate height, release the first limiting rod 81. At this time, the first spring 83 resets, driving the first limiting rod 81 to move inward and snap into the sub-groove of the limiting groove 82 at the corresponding height, thereby limiting the cutting blade 7. At the same time, the rotating shaft 6 moves up and down, driving the second gear 96, the L-shaped fixing rod 95, the first gear 94, and the first toothed rod 93 to move up and down. At this time, the second spring 92 undergoes adaptive deformation accordingly. After the adjustment is completed, close the rotating door 71. Then, start the servo motor 5. The output shaft of the servo motor 5 drives the rotating shaft 6 to rotate, thereby driving the cutting blade 7 to rotate, and at the same time driving the second gear 96 to rotate. The second gear 96 is in meshing transmission with the first toothed rod 93 through the first gear 94, driving the L-shaped fixing rod 95, the servo motor 5, the motor bracket 51, the rotating shaft 6, the cutting blade 7, the sliding rod 4, and the first slide rail 3 to move backward, so that the cutting blade 7 cuts the compact shelving. After the cutting is completed, control the output shaft of the servo motor 5 to reverse, driving the rotating shaft 6, the cutting blade 7, the second gear 96, and the first gear 94 to reverse, thereby driving the L-shaped fixing rod 95, the servo motor 5, the motor bracket 51, the rotating shaft 6, the cutting blade 7, the sliding rod 4, and the first slide rail 3 to move forward and reset. Turn off the servo motor 5, and then take away the cut compact shelving.

[0035] Embodiment 2

[0036] Based on Embodiment 1, as Figure 2 、 Figure 3 、 Figure 10 and Figure 11As shown in the figure, it further includes a pulling mechanism 10 for controlling the simultaneous outward movement of the first limiting rod 81. The pulling mechanism 10 includes an n-shaped fixing rod 101, a first pulling rope 102, a first guiding wheel 103, and a first wire reel 104. The n-shaped fixing rod 101 is welded to the right side of the sliding rod 4. Both first limiting rods 81 are slidably connected to the n-shaped fixing rod 101. Three first guiding wheels 103 are rotatably connected to the front and rear sides of the right wall of the n-shaped fixing rod 101. The first wire reel 104 is rotatably connected to the middle of the right side of the n-shaped fixing rod 101. The first pulling ropes 102 are connected to both the front and rear sides of the first wire reel 104. The front first pulling rope 102 bypasses the three front first guiding wheels 103 and is connected to the front first limiting rod 81. The rear first pulling rope 102 bypasses the three rear first guiding wheels 103 and is connected to the rear first limiting rod 81. When it is necessary to adjust the height of the cutting blade 7, manually rotate the first wire reel 104 so that the first wire reel 104 winds up the first pulling rope 102, and then drive the first limiting rod 81 to move outward through the first pulling rope 102. At this time, the first spring 83 is compressed. In this way, the first limiting rod 81 can be simultaneously pulled outward, and there is no need to manually control the first limiting rod 81 separately, reducing the operation difficulty. After the height adjustment is completed, release the first wire reel 104. At this time, the first spring 83 resets, drives the first limiting rod 81 to move inward and reset, and then drives the first wire reel 104 to reverse and reset through the first pulling rope 102, so that the first wire reel 104 relaxes the first pulling rope 102.

[0037] As Figure 2 , Figure 12 and Figure 13 shown in the figure, it further includes a limiting and fixing mechanism 11 for supporting the first toothed rod 93. The limiting and fixing mechanism 11 includes a fixing ring 111, a second limiting rod 112, and a third spring 113. Six fixing rings 111 are vertically and evenly spaced and connected to the right parts of the opposite sides of the two second slide rails 91. The second limiting rods 112 for supporting the first toothed rod 93 are slidably connected to the twelve fixing rings 111. The first toothed rod 93 contacts the second limiting rod 112. The third springs 113 are sleeved on the right sides of the twelve second limiting rods 112. The two ends of the third spring 113 are respectively connected to the second limiting rod 112 and the fixing ring 111. When it is necessary to adjust the height, the staff manually pulls the second limiting rod 112 to the right. At this time, the third spring 113 is stretched. Then the first toothed rod 93 moves up and down with the first gear 94 to adjust the position. After the adjustment is completed, release the second limiting rod 112. At this time, the third spring 113 resets, drives the second limiting rod 112 to move leftward and reset, so that the second limiting rod 112 at the corresponding position supports the first toothed rod 93. In this way, it is possible to prevent the second spring 92 from weakening in elasticity due to long-term use, thereby extending the service life of the second spring 92.

[0038] such as Figure 2 and Figure 4 and Figure 14 and Figure 15As shown, it further includes a winding mechanism 12 for automatically limiting the first toothed rod 93. The winding mechanism 12 includes a second toothed rod 121, a third gear 122, a fixed shaft 123, a second wire reel 124, a second pulling rope 125, a second guide wheel 126, a connecting rod 127, a support rod 128 and a fourth spring 129. Support rods 128 are slidably connected to both the front and rear sides of the n-shaped fixed rod 101. A second toothed rod 121 is connected between the upper parts of the two support rods 128. The top of the second toothed rod 121 contacts the housing 1. Fourth springs 129 are sleeved on the lower parts of the two support rods 128. The two ends of the two fourth springs 129 are respectively connected to the n-shaped fixed rod 101 and the support rod 128. The right front side of the upper part inside the housing 1 is rotatably connected with a fixed shaft 123. A third gear 122 is connected to the left side of the fixed shaft 123 by a key. The third gear 122 meshes with the second toothed rod 121. The left side of the fixed shaft 123 is connected with a second wire reel 124. The second wire reel 124 is located on the left side of the third gear 122. Second pulling ropes 125 are connected to both the front and rear sides of the second wire reel 124. A connecting rod 127 is connected between the right sides of the six second limiting rods 112 on the front side. A connecting rod 127 is connected between the right sides of the six second limiting rods 112 on the rear side. A set of second guide wheels 126 is connected to both the front and rear sides of the inner wall of the housing 1. Each set is composed of three second guide wheels 126. One end of the second pulling rope 125 on the front side bypasses the set of second guide wheels 126 on the front side and is connected to the right side of the connecting rod 127 on the front side. One end of the second pulling rope 125 on the rear side bypasses the set of second guide wheels 126 on the rear side and is connected to the right side of the connecting rod 127 on the rear side.Initially, the second wire reel 124 winds the second pulling rope 125, causing the second pulling rope 125 to pull the second limiting rod 112 through the connecting rod 127 to a state where it does not block the first rack 93. In this way, the height adjustment of the cutting blade 7 is not affected. The third spring 113 is stretched. As the sliding rod 4 drives the n-shaped fixing rod 101 to move up and down to adjust the position, the fourth spring 129 undergoes adaptive deformation accordingly. Under the action of the fourth spring 129, the second rack 121 can always be kept in close contact with the housing 1. During cutting, the n-shaped fixing rod 101 moves back and forth to drive the second rack 121 to move back and forth through the support rod 128, thereby driving the third gear 122, the fixed shaft 123, and the second wire reel 124 to rotate, causing the second wire reel 124 to relax the second pulling rope 125. At this time, the third spring 113 resets, driving the second limiting rod 112 to move leftward and reset to limit the first rack 93. In this way, when the cutting blade 7 cuts the dense rack, the second limiting rod 112 can limit the first rack 93, thereby preventing the first rack 93 from shaking. After cutting, the second rack 121 moves forward and resets to engage with the third gear 122, driving the fixed shaft 123 and the second wire reel 124 to reverse and reset, causing the second wire reel 124 to wind the second pulling rope 125, and then driving the second limiting rod 112 to move rightward through the second pulling rope 125 and the connecting rod 127 to no longer limit the first rack 93, and the third spring 113 is stretched.

[0039] Such as Figure 2 and Figure 16As shown in the figure, it further includes a clamping mechanism 13 for clamping the compact shelving. The clamping mechanism 13 includes a cylinder 131, a support plate 132, a screw rod 133, and a clamping plate 134. The front and rear sides of the left part of the outer shell 1 are fixedly connected with cylinders 131 through bolts. The inner sides of the telescopic rods of the two cylinders 131 are connected with support plates 132. The upper parts of the two support plates 132 are threadedly connected with screw rods 133. The bottoms of the two screw rods 133 are rotatably connected with clamping plates 134. When in use, start the cylinder 131. The contraction of the telescopic rod of the cylinder 131 drives the support plate 132 to move outward, drives the screw rod 133 and the clamping plate 134 to move outward. Then place the compact shelving to be cut between the two support plates 132. Then control the telescopic rod of the cylinder 131 to extend and reset, drive the support plate 132, the screw rod 133, and the clamping plate 134 to move inward and reset, so that the compact shelving to be cut is located on the two support plates 132. Then rotate the screw rod 133. The screw rod 133 drives the clamping plate 134 to move downward to clamp the compact shelving, achieving the purpose of fixing the compact shelving. In this way, the stability during the cutting of the compact shelving can be improved. After cutting, rotate the screw rod 133 in the reverse direction, drive the clamping plate 134 to move upward to release the compact shelving. Then start the cylinder 131, control the telescopic rod of the cylinder 131 to drive the support plate 132, the screw rod 133, and the clamping plate 134 to move outward and reset, so that the support plate 132 is separated from the compact shelving. Then take away the compact shelving and turn off the cylinder 131.
