Description

Technical Field

[0001] This utility model relates to the technical field of corrugated cardboard box production equipment, and in particular to a corrugated cardboard box production stacking rack with buffer limit. Background Technology

[0002] In the production of corrugated cardboard boxes, the stability of the stacking process is crucial to product quality and production efficiency.

[0003] Existing stacking racks have significant technical shortcomings: On the one hand, the cushioning structure design is rigid, generally using elastic components with a single hardness, which cannot dynamically adjust the cushioning force according to the thickness difference and material characteristics of corrugated boxes. This often leads to damage to the outer shell of the boxes due to cushioning imbalance during stacking. On the other hand, the adaptability of the limiting mechanism is poor. The side baffles are mostly designed with fixed sizes, making it difficult to form a stable constraint on boxes of different widths. When changing the size of the boxes, it is necessary to disassemble and replace the side baffles of the corresponding size, which is not only cumbersome to operate, but also directly reduces work efficiency. Therefore, a corrugated box production stacking rack with cushioning and limiting is needed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a corrugated cardboard box production stacking rack with buffer limit.

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

[0006] A corrugated cardboard box production stacking rack with buffer limit includes a stacking rack. A base plate is fixedly connected to the bottom inner wall of both sides of the stacking rack. A buffer mechanism is provided on the top of the base plate. The buffer mechanism includes fixing blocks, each of which is fixedly connected to the top four corners of the base plate. Support rods are fixedly connected to opposite sides of the fixing blocks. A fixing mechanism is provided on one side of the stacking rack. The fixing mechanism includes a sleeve, which is fixedly connected to the inner wall of one side of the stacking rack. A screw is rotatably connected to one end of the sleeve.

[0007] As a further embodiment of this utility model: a sliding sleeve is respectively fitted on both sides of the surface of the support rod, and a spring is fitted on the support rod surface on the opposite side of the sliding sleeve.

[0008] As a further embodiment of this utility model: rocker arms are rotatably connected to the sliding sleeves on both sides of the spring, and a placement plate is rotatably connected to the end of the rocker arm away from the sliding sleeve. The placement plate is slidably connected to the inner walls on both sides of the stacking rack.

[0009] As a further embodiment of this utility model: dampers are fixedly connected to the top of the fixing blocks at the four corners of the base plate, and springs are sleeved on the surface of the dampers.

[0010] As a further embodiment of this utility model: one end of the screw is fixedly connected to a handle, the end of the screw away from the handle is rotatably connected to the inner wall of the end of the sleeve, and a sliding cylinder is threaded onto the surface of the screw, the sliding cylinder being slidably connected to the inner wall of the sleeve.

[0011] As a further embodiment of this utility model: the surface of the slide cylinder is provided with sliding grooves, the sliding grooves are slidably connected to the end of the sleeve away from the handle, and a rubber plate is fixedly connected to the end of the slide cylinder.

[0012] As a further improvement of this utility model: the bottom two sides of the stacking rack are respectively fixedly connected with the locking blocks, and the top two sides of the stacking rack are respectively provided with locking slots, which are adapted to the locking blocks.

[0013] Compared with the prior art, this utility model provides a corrugated cardboard box production stacking rack with buffer limit, which has the following beneficial effects:

[0014] 1. This corrugated cardboard box production and stacking rack with buffer limit is equipped with a buffer mechanism. When the placement plate presses down on the rockers at its four corners, the four rockers drive four connected sliding sleeves to slide back and forth on the surfaces of the two support rods. During this process, two springs are compressed, and at the same time, the placement plate presses down on the dampers at its four corners. The dampers play the main buffering role. During this process, springs are also compressed. The main function of springs one and two is to drive the dampers and placement plate to reset in the non-working state. It can dynamically adjust the buffering force according to the thickness difference and material characteristics of the corrugated cardboard box, reducing the situation where the outer shell of the cardboard box is often damaged due to buffer imbalance during stacking.

[0015] 2. This corrugated cardboard box production and stacking rack with buffer limit is equipped with a fixing mechanism. Turning the handle drives the screw to rotate. Since the slide cylinder is threadedly connected to the screw, the slide cylinder will slide along the inner wall of the sleeve during the rotation of the screw. As the slide cylinder moves, it also drives the rubber plate to move until the rubber plate is tightly attached to the side wall of the cardboard box. The friction of the rubber plate fixes the cardboard box. It can form a stable constraint for cardboard boxes of different widths. There is no need to disassemble and replace the side baffles of the corresponding size. It is convenient to operate and improves work efficiency.

[0016] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] A corrugated cardboard box production stacking rack with cushioning and limiting, such as... Figure 1 , Figure 2 and Figure 3 As shown, the stacking rack 1 is included. The bottom inner walls on both sides of the stacking rack 1 are fixedly connected to the base plate 3. The top of the base plate 3 is provided with a buffer mechanism 2. The buffer mechanism 2 includes a fixing block 201. The fixing block 201 is fixedly connected to the top four corners of the base plate 3. The opposite side of the fixing block 201 is fixedly connected to the support rod 202. The stacking rack 1 is provided with a fixing mechanism 4 on one side. The fixing mechanism 4 includes a sleeve 401. The sleeve 401 is fixedly connected to the inner wall of one side of the stacking rack 1. One end of the sleeve 401 is rotatably connected to the screw 402.

[0026] During operation, the buffer mechanism 2 can dynamically adjust the buffering force according to the thickness difference and material characteristics of the corrugated cardboard box, reducing the possibility of shell damage caused by buffer imbalance during the stacking process; and the fixing mechanism 4 can form a stable constraint on cardboard boxes of different widths, without the need to disassemble and replace the side baffles of the corresponding size, making operation convenient and improving work efficiency.

[0027] In order to cushion the corrugated cardboard boxes during stacking, such as Figure 1 and Figure 2 As shown, a sliding sleeve 203 is sleeved on both sides of the surface of the support rod 202, and a spring 204 is sleeved on the surface of the support rod 202 on the opposite side of the sliding sleeve 203.

[0028] The sliding sleeves 203 on both sides of the spring 204 are rotatably connected to rocker arms 205. The end of the rocker arm 205 away from the sliding sleeve 203 is rotatably connected to a placement plate 206. The placement plate 206 is slidably connected to the inner walls on both sides of the stacking rack 1.

[0029] The top of the four corner fixing blocks 201 at the top of the base plate 3 is fixedly connected to dampers 207 respectively, and springs 208 are sleeved on the surface of the dampers 207.

[0030] First, the cardboard box is placed on top of the placement plate 206. During cushioning, according to the weight of the cardboard box, the placement plate 206 presses down on the rocker arms 205 at its four corners to rotate. The four rocker arms 205 drive the four connected sliding sleeves 203 to slide back and forth on the surface of the two support rods 202. During this period, the two springs 204 are compressed. At the same time, the placement plate 206 presses down on the dampers 207 at its four corners. The dampers 207 play the main cushioning role. During this period, the spring 208 is also compressed. The main function of the two springs 204 and the spring 208 is to drive the dampers 207 and the placement plate 206 to reset in the non-working state. It can dynamically adjust the cushioning force according to the thickness difference and material characteristics of the corrugated cardboard box, reducing the situation where the outer shell of the cardboard box is often damaged due to cushioning imbalance during stacking.

[0031] In order to secure the cushioned corrugated cardboard box, such as Figure 1 , Figure 3 and Figure 4 As shown, a handle 406 is fixedly connected to one end of the screw 402, and the end of the screw 402 away from the handle 406 is rotatably connected to the inner wall of the end of the sleeve 401. A slide cylinder 403 is threaded onto the surface of the screw 402, and the slide cylinder 403 is slidably connected to the inner wall of the sleeve 401.

[0032] The surface of the slide cylinder 403 is provided with slide grooves 404, which are slidably connected to the end of the sleeve 401 away from the handle 406. A rubber plate 405 is fixedly connected to the end of the slide cylinder 403.

[0033] After buffering, to prevent the carton from shifting or falling, it needs to be secured. Turning handle 406 drives screw 402 to rotate. Since the sliding cylinder 403 is threadedly connected to screw 402, the rotation of screw 402 will cause the sliding cylinder 403 to slide along the inner wall of sleeve 401. As the sliding cylinder 403 moves, it also drives the rubber plate 405 to move until the rubber plate 405 is tightly attached to the side wall of the carton. The friction of the rubber plate 405 secures the carton, which can form a stable constraint on cartons of different widths. There is no need to disassemble and replace the side baffles of the corresponding size, making operation convenient and improving work efficiency.

[0034] The bottom two sides of the stacking rack 1 are fixedly connected with the card blocks 6 respectively, and the top two sides of the stacking rack 1 are respectively provided with card slots 5, which are adapted to the card blocks 6.

[0035] The design of the stacking rack 1 also takes into account the convenience of fixing and connecting. The bottom card block 6 and the top card slot 5 are compatible, so that multiple stacking racks 1 can be easily stacked together, ensuring the stability of the carton stacking process.

[0036] Working principle: During cushioning, based on the weight of the carton, the placement plate 206 presses down on the rocker arms 205 at its four corners to rotate. The four rocker arms 205 drive the four connected sliding sleeves 203 to slide back and forth on the surfaces of the two support rods 202. During this time, the two springs 204 are compressed. At the same time, the placement plate 206 presses down on the dampers 207 at its four corners. The dampers 207 play the main cushioning role. During this time, the spring 208 is also compressed. The main function of the two springs 204 and the spring 208 is to drive the dampers. 207 and the placement plate 206 are reset in the non-working state. After buffering, the carton needs to be fixed. Turning the handle 406 drives the screw 402 to rotate. Since the slide cylinder 403 is threadedly connected to the screw 402, the slide cylinder 403 will slide along the inner wall of the sleeve 401 during the rotation of the screw 402. While the slide cylinder 403 moves, it drives the rubber plate 405 to move until the rubber plate 405 is tightly attached to the side wall of the carton. The carton is fixed by the friction of the rubber plate 405.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
