Description

Technical Field

[0001] This application relates to the field of carton production, and in particular to a carton binding device. Background Technology

[0002] A carton binding machine is a device used to bind and secure the edges or joints of cartons, and is widely used in the packaging industry. The operator places the carton to be bound into the binding position, and the control system controls the movement of the binding head according to preset parameters. The binding needle, driven by power, penetrates the carton, then a creasing device presses out creases, and finally a cutter cuts the binding thread, completing one binding cycle.

[0003] A Chinese patent with publication number CN107813543A discloses a small carton binding processing device, including a binding device bracket, a motor, a binding machine, and an operating table. The binding machine is controlled to start working. By controlling the foot pedal operation key on the top of the metal base plate, the operator can free up their hands to place the carton. The carton is placed on the operating table, and the foot pedal operation key is used to control the binding machine, which drives the internal transmission wheel and binding needle to press down for binding.

[0004] However, the width of the workbench is fixed. When it is necessary to bind cartons of different sizes, there may be a situation where the cartons are difficult to place stably on the workbench due to its small width. Utility Model Content

[0005] In order to facilitate the stable placement of cartons of different sizes on the workbench, this application provides a carton binding device.

[0006] The cardboard box binding device provided in this application adopts the following technical solution:

[0007] A carton binding device includes an operating table for placing cartons and a binding mechanism for binding cartons. A support rod is provided on one side of the operating table, and two sets of telescopic components are connected between the operating table and the support rod. Each set of telescopic components includes a first link and a second link that are hinged to each other. The end of the first link away from the second link is hinged to the operating table, and the end of the second link away from the first link is hinged to the support rod. The first link and the second link in each set of telescopic components are inclined in a direction that brings them closer to each other.

[0008] By adopting the above technical solution, the hinged design between the first and second connecting rods allows for flexible adjustment of the distance between the support rod and the operating table. This structure not only facilitates adjustment of the effective width of the operating table according to actual needs, but also ensures stable support for cartons of different sizes, thereby improving the applicability and operational flexibility of the binding device and enabling cartons of different sizes to be placed relatively stably on the operating table.

[0009] Preferably, both ends of the support rod are fixedly connected to fixing blocks, one fixing block corresponds to one second connecting rod, and each fixing block is connected to a locking component. The locking component includes bolts for the fixing blocks and the second connecting rod in sequence, and the lower end of the bolts is threaded with a nut that abuts against the second connecting rod.

[0010] By adopting the above technical solution, the locking component can effectively fix the relative position between the support rod and the second connecting rod, reducing the occurrence of displacement or shaking of the support rod due to external forces during the binding process, and improving the stability of the carton binding device. The use of bolts and nuts makes the connection between the fixing block and the second connecting rod more secure, while also facilitating disassembly and adjustment, thus improving the flexibility and ease of operation of the device.

[0011] Preferably, both ends of the support rod are fixedly connected to auxiliary blocks, each auxiliary block has a through hole, and each nut is slidably connected to one of the through holes along the length of the bolt.

[0012] By adopting the above technical solution, the nut can slide in the through hole along the length of the bolt. This structural design allows the adjustment of the locking degree between the second connecting rod and the fixed block to be achieved simply by rotating the bolt in both directions, without the need for additional manual intervention to restrict the rotation of the nut, making the operation more convenient and efficient.

[0013] Preferably, a guide block is fixedly connected to the inner sidewall of the through hole, and a guide groove is provided on the sidewall of the nut, with the guide block and the guide groove being slidably inserted into each other.

[0014] By adopting the above technical solution, the guide block can effectively restrict the rotation trend of the nut when the bolt is rotated in both directions, so that the nut can only move vertically up and down. During this process, the guide block and the guide groove cooperate with each other. When the nut moves along the bolt, the guide block slides smoothly along the guide groove, ensuring that the movement of the nut is more stable and precise, thereby improving the adjustment reliability and operation convenience of the device.

[0015] Preferably, the guide groove has nuts penetrating both ends along its length.

[0016] By adopting the above technical solution, stable sliding of the nut on the guide block is achieved, while allowing the nut to detach from both ends of the guide groove and the guide block. This design not only improves the assembly flexibility between the nut and the guide block, but also facilitates quick disassembly and installation of the nut when needed.

[0017] Preferably, the end of the bolt away from the nut is provided with a cap, and the cap has a rectangular groove.

[0018] By adopting the above technical solution, the rectangular groove makes it easier for the tool to apply torque to the bolt, thereby facilitating the tightening or loosening of the bolt and improving the efficiency of assembly and adjustment.

[0019] Preferably, a support assembly is installed between the support rod and the operating table. The support assembly includes a sleeve fixedly connected to the operating table and a sleeve rod connected to the support rod, wherein the sleeve rod is inserted into the sleeve.

[0020] By adopting the above technical solution, the support rod and the operating table are connected by a support assembly, which consists of a sleeve and a rod. The sleeve is fixed to the operating table, and the rod is connected to the support rod and inserted into the sleeve to achieve a plug-in connection. This solution can enhance the connection stability between the support rod and the operating table, that is, strengthen the connection between the operating table and the support rod bracket, while providing a certain width adjustment function, so that the device can adapt to the binding needs of cartons of different sizes.

[0021] Preferably, a support assembly is installed between the support rod and the operating table. The support assembly includes a sleeve fixedly connected to the operating table and a sleeve rod connected to the support rod, wherein the sleeve rod is inserted into the sleeve.

[0022] By adopting the above technical solution, rotating the sleeve rod allows it to move relative to the sleeve tube, thereby adjusting the displacement between the sleeve rod and the sleeve tube. This facilitates adjusting the distance between the support rod and the operating table, thus adapting to different sizes of cartons. Furthermore, when the sleeve rod stops rotating, it locks relative to the sleeve tube, and the support rod and the operating table also lock together.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. It allows cartons of different sizes to be placed stably on the worktable;

[0025] 2. The fixing component can effectively fix the relative position between the support rod and the second connecting rod, reducing the occurrence of displacement or shaking of the support rod due to external force during the binding process;

[0026] 3. When adjusting the locking degree between the second connecting rod and the fixed block, it can be achieved simply by rotating the bolt in both directions, without the need for additional manual intervention to restrict the rotation of the nut. Attached Figure Description

[0031] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.

[0032] This application discloses a carton binding device. (Refer to...) Figure 1 and Figure 2 The carton binding device includes a support frame 1, an operating table 2 for placing cartons, and a binding mechanism 3 located above the operating table 2 for binding cartons. The operating table 2 is fixedly connected to the support frame 1. A support rod 4 is provided on one side of the operating table 2, and two sets of telescopic components 5 are connected between the operating table 2 and the support rod 4.

[0033] The distance between the support rod 4 and the operating table 2 can be adjusted by adjusting the telescopic component 5, which makes it easier to support irregular cardboard boxes.

[0034] Reference Figure 2 and Figure 3 Each telescopic assembly 5 includes a first link 51 and a second link 52 that are hinged to each other. The end of the first link 51 away from the second link 52 is hinged to the operating table 2, and the end of the second link 52 away from the first link 51 is hinged to the support rod 4. The first link 51 and the second link 52 in each telescopic assembly 5 are inclined in a direction that brings them closer to each other.

[0035] Move the support rod 4 away from the operating table 2. The movement of the support rod 4 will drive the first connecting rod 51 and the second connecting rod 52 to rotate, thereby achieving the effect of adjusting the width of the operating table 2.

[0036] The first link 51 and the second link 52 can be made of metal, such as stainless steel or aluminum alloy, or high-strength plastic to ensure their structural strength.

[0037] Both ends of the support rod 4 are fixedly connected to a fixing block 6. One fixing block 6 corresponds to one second link 52. Each fixing block 6 is connected to a locking element 7 for locking the second link 52 and the fixing block 6.

[0038] Reference Figure 2 and Figure 3The locking component 7 includes a bolt 71 that passes through the fixing block 6 and the second connecting rod 52 in sequence, and a nut 72 that is threadedly connected to the lower end of the bolt 71 and tightly abuts against the second connecting rod 52. The fixing block 6 can be fixed to the support rod 4 by welding, bolting 71 connection or bonding.

[0039] Rotate bolt 71 relative to nut 72. When nut 72 is not tightly against second connecting rod 52, second connecting rod 52 and fixed block 6 can rotate relative to each other, which makes it easy to adjust the position of support rod 4 relative to operating table 2.

[0040] To facilitate the rotation of bolt 71 by the operator, thereby enabling the locking and unlocking of the second connecting rod 52 and the fixing block 6, auxiliary blocks 73 are fixedly connected to both ends of the support rod 4. Each auxiliary block 73 has a through hole 731, which extends vertically through the auxiliary block 73. Each nut 72 is slidably connected to one of the through holes 731 along the length of bolt 71.

[0041] A guide block 74 is fixedly connected to the inner wall of the through hole 731, and a guide groove 721 is provided on the side wall of the nut 72. The guide block 74 is slidably inserted into the guide groove 721. The guide block 74 can be made of metal or hard plastic. The length direction of the guide groove 721 is consistent with the sliding direction of the nut 72 to ensure that the nut 72 will not deviate during sliding.

[0042] When rotating bolt 71, the operator does not need to apply external force to restrict the rotation of nut 72. At this time, the relative rotation between bolt 71 and nut 72 can be completed, which is simple and convenient to operate.

[0043] Both ends of the guide groove 721 pass through the nut 72 along its length, so that the nut 72 can be detached and separated from the auxiliary block 73. The bolt 71 is provided with a cap 711 at the end away from the nut 72. The cap 711 has a rectangular groove 7111. The design of the rectangular groove 7111 facilitates the tightening or loosening of the bolt 71 and nut 72 using a screwdriver or other tools.

[0044] To facilitate the reinforcement of the connection between the support rod 4 and the operating table 2, a support assembly 8 is installed between the support rod 4 and the operating table 2.

[0045] The support assembly 8 includes a sleeve 81 fixedly connected to the operating table 2, and a sleeve rod 82 rotatably connected to the support rod 4. The end of the sleeve rod 82 away from the support rod 4 is inserted into the sleeve 81 and threadedly connected to the sleeve 81.

[0046] When it is necessary to adjust the distance between the support rod 4 and the operating table 2, the sleeve 82 is rotated relative to the support column. At this time, the sleeve 82 rotates and moves relative to the sleeve 81, thereby pushing the support rod 4 to move closer to or further away from the operating table 2.

[0047] The implementation principle of the carton binding device in this application embodiment is as follows: When it is necessary to adjust the distance between the support rod 4 and the operating table 2, each bolt 71 is rotated with the aid of a tool, thereby releasing the lock between the second connecting rod 52 and the fixing block 6. Then, the sleeve rod 82 is rotated forward or in the opposite direction, and the movement of the sleeve rod 82 relative to the sleeve 81 pushes the support rod 4 to move closer to or away from the operating table 2 until the required distance is reached between the support rod 4 and the operating table 2. Finally, each bolt 71 is rotated so that the bolt 71 and the nut 72 lock each second connecting rod 52 and the fixing block 6.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
