Description

Technical Field

[0001] The utility model belongs to the technical field of carton sealing machines, and particularly relates to a box body guiding and fixing device for a carton sealing machine. Background Art

[0002] A carton sealing machine is a device used for sealing cartons. During the carton sealing process, it is necessary to fold the top cover of the box body and then seal it with tape. Due to design and structural problems of existing carton sealing machines, the box body is folded manually, which has low efficiency and high cost. Moreover, when the carton enters the carton sealing machine, the top cover of the box body is likely to get stuck at the entrance, causing the carton sealing machine to stop working and affecting work efficiency.

[0003] A patent with the publication number of CN221068706U discloses a box body guiding component for a carton sealing and conveying device, including a bottom plate. The top of the bottom plate is provided with both a pushing mechanism and a conveying mechanism. The pushing mechanism is used to adjust the distance between devices, and the conveying mechanism is used to drive the box body to move on the device; an elastic support mechanism is fixedly connected to the pushing mechanism.

[0004] The above solution can support and fix the box body through an elastic support structure to prevent the box body from shifting during movement. Since the carton sealing machine itself seals the box body by pressing down, when the top cover of the box body is not in the folded state, it is easily damaged by the carton sealing machine. Therefore, the operator needs to ensure that the top cover of the box body before packaging is in the folded state. The above solution can only fix the box body itself and cannot fold the top cover of the box body through the device before the box body is packaged. For this reason, manual operation is required, which is time-consuming and laborious. Moreover, manual folding is performed in the environment where the carton sealing machine presses down, which has certain safety hazards. Summary of the Utility Model

[0005] To solve the problems in the background art, the utility model provides a box body guiding and fixing device for a carton sealing machine.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

Those skilled in the art should know that the following described embodiments are a part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without making creative efforts fall within the scope of protection of the present utility model.

[0023] As Figures 1-4As shown in the figure, the technical solution adopted by the utility model is as follows: A box guiding and fixing device for a cartoning machine, including a main body 1, on which a conveying mechanism is provided. The conveying mechanism includes a first motor 2, which is fixedly installed on the main body 1. A groove 4 is opened at the top of the main body 1, and two conveying rollers are horizontally rotatably arranged in the groove 4. The two conveying rollers are in the same horizontal plane, and a conveyor belt 5 is sleeved between the two conveying rollers in a driving manner. Both ends of each conveying roller are rotatably connected to the main body 1, and one of the conveying rollers is coaxially fixedly connected to the output shaft of the first motor 2.

[0024] Two limiting components are slidably arranged on the main body 1, and the two limiting components slide towards or away from each other on the main body 1. Each limiting component includes a clamping plate 6. Two first chutes and two second chutes are opened at the top of the main body 1. The two clamping plates 6 correspond to the two first chutes one by one and also correspond to the two second chutes one by one. Each clamping plate 6 is slidably arranged in the corresponding first chute in a limiting manner and is also slidably arranged in the corresponding second chute in a limiting manner. Moreover, the opposite sides of the two clamping plates 6 face the conveyor belt 5, and rubber pads (not shown in the figure) are provided on the opposite sides of the two clamping plates 6.

[0025] A lead screw 10 is horizontally rotatably arranged in the groove 4, and the central axis of the lead screw 10 is parallel to the central axis of the conveying roller. The two ends of the lead screw 10 correspond to the two first chutes one by one, and both ends of the lead screw 10 rotatably extend into the corresponding first chutes. In addition, there is a threaded section at each part of the lead screw 10 located in the two first chutes, and the thread directions of the two threaded sections are opposite. Each clamping plate 6 is in threaded cooperation with the threaded section of the lead screw 10 in the corresponding first chute. A second motor 3 is fixedly installed on the main body 1, and the output shaft of the second motor 3 is coaxially fixedly connected to one end of the lead screw 10.

[0026] Each limiting component is provided with a pushing member, and the two pushing members are symmetric about the conveyor belt 5.

[0027] Each pushing member includes a hydraulic cylinder 7. A placement groove is opened on each clamping plate 6, and a hydraulic cylinder 7 is fixedly installed vertically in each placement groove. The telescopic shaft of each hydraulic cylinder 7 is fixedly connected to a fixed block, and a first cylinder 8 is fixedly arranged on each fixed block. The telescopic shafts of the two first cylinders 8 face each other and face the box body. The telescopic shafts of the two first cylinders 8 are both fixedly connected to a telescopic rod, and a push plate 9 is fixedly arranged at the end of each telescopic rod away from the first cylinder 8. A spring 12 is sleeved on each of the two telescopic rods. One end of the spring 12 is fixedly connected to the first cylinder 8, and the other end of the spring 12 is fixedly connected to the push plate 9. In addition, a tape (not shown in the figure) is pasted on the side of each push plate 9 close to the box body, and the smooth side of the tape faces the box body to reduce the friction on the box body.

[0028] Each limiting component is in driving cooperation with the connected pushing member.

[0029] Two second cylinders 11 are fixedly installed on the main body 1. The two second cylinders 11 correspond to the two second chutes one by one. The telescopic shaft of each second cylinder 11 slides and extends into the corresponding second chute. Moreover, the telescopic shaft of each second cylinder 11 is fixedly connected to one end of the clamping plate 6 in the corresponding second chute close to the conveyor belt 5. The two second cylinders 11 correspond to the two first cylinders 8 one by one, and each second cylinder 11 is communicated with the corresponding first cylinder 8 through an air pipe.

[0030] Working principle: When the box needs to be sealed, first place the box to be sealed on the upper surface of the conveyor belt 5. Start the first motor 2, and the output shaft of the first motor 2 drives the conveyor belt 5 to rotate through the conveying roller, so as to transport the box on the conveyor belt 5.

[0031] When the box is transported between the two limiting components, stop the first motor 2. Start the second motor 3, and the output shaft of the second motor 3 drives the lead screw 10 to rotate. The lead screw 10 drives the two clamping plates 6 to slide in the chute along the central axis of the lead screw 10 towards the direction close to the box, so as to limit and fix the box and prevent the box from shifting during the sealing process.

[0032] During the process of the clamping plate 6 approaching the box, it will push the telescopic shaft of the second cylinder 11 to contract, thereby driving the telescopic shaft of the first cylinder 8 to extend. The extension of the telescopic shaft of the first cylinder 8 will push the two push plates 9 closer to each other.

[0033] In the initial state, the side of the push plate 9 facing the box and the side of the clamping plate 6 facing the box are in the same vertical plane, and the telescopic rod is in the maximum extended state under the elastic action of the spring 12. During the sliding process of the clamping plate 6, it will drive the push plate 9 to slide synchronously. Under the push of the telescopic shaft of the first cylinder 8, the push plate 9 contacts the box first. As the clamping plate 6 continues to slide, the box reacts on the telescopic rod through the push plate 9, causing the telescopic rod to gradually contract. During this process, the compression deformation of the spring 12 gradually increases until the clamping plate 6 contacts the box.

[0034] Subsequently, start the hydraulic cylinder 7 and control the telescopic shaft of the hydraulic cylinder 7 to extend. The telescopic shaft of the hydraulic cylinder 7 pushes the push plate 9 to move upward through the first cylinder 8. During the upward movement of the push plate 9, it will push the top cover of the box, which is convenient for lifting the top cover that is pressed backwards during assembly and avoiding the situation that the top cover is turned outwards of the box.

[0035] When the top cover of the box is in the vertical state, the push plate 9 just reaches the connection and rotation part between the top cover and the side of the box. At this time, under the elastic action of the spring 12, the push plate 9 pushes the top cover of the box to fold inwards towards the box, which is convenient for subsequent sealing.

[0036] After the case sealing is completed, control the output shaft of the second motor 3 to rotate in the reverse direction. The second motor 3 drives the two clamping plates 6 to slide away from the box body through the lead screw 10, thereby releasing the restriction of the clamping plates 6 on the box body. At the same time, during the sliding process of the clamping plates 6, the telescopic shaft of the second cylinder 11 will be pulled to extend, thereby controlling the telescopic shaft of the first cylinder 8 to contract, and finally completing the reset of the push plate 9.

[0037] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
