Description

Technical Field

[0001] The utility model relates to the technical field of carton sealing and binding, in particular to a stable carton sealing machine. Background Art

[0002] At present, cartons filled with items need to be sealed to better protect the items in the box. However, when heavy items are packaged, the tape cannot seal them completely and the seals often crack. Therefore, most of the boxes are sealed by binding.

[0003] In order to improve stability during binding, most existing carton sealing machines use clamping devices for clamping. However, most existing equipment clamps by adding a separate motor or a manually operated drive structure such as an electric push rod. For example, patent announcement No. CN220054435U discloses a high-quality and stable corrugated cardboard box automatic carton sealing machine and CN210082514U discloses a corrugated cardboard box nailing device with adjustable clamping distance. Although this is convenient, it is less efficient in batch processing. Each time a carton is sealed, it is necessary to manually clamp the box body first, and then perform the sealing operation, which is relatively time-consuming.

[0004] Therefore, the applicant proposes a stable carton sealing machine to solve the problem. Utility Model Content

[0013] Compared with the related art, a stable carton sealing machine provided by the present invention has the following

[0014] Beneficial effects:

[0015] The present invention provides a stable carton sealing machine. By designing a positioning component, when binding, the hydraulic rod on the frame is started to make the lifting plate descend, so that the binding head and the rack plate descend together. When the rack plate moves downward, the gear rotates, and then the lead screw rotates to drive the moving rod to move. At this time, the moving rod will push the clamping plate, and the clamping plate moves stably under the sliding cooperation of the four sleeve rods and the cross bar. Finally, when the binding head descends to the binding position, the two clamping plates complete the clamping. In this way, during batch processing, it is not necessary to fix and then seal the box first, and it is not necessary to manually control the clamping, thus effectively improving the processing efficiency and reducing the processing time.

[0016] The present invention provides a stable carton sealing machine. Through the pressing plate assembly, when the lifting plate descends, the pressing plate will first contact the top of the carton, thereby flattening the top surface of the carton. The buffer spring B and the sliding rod can provide a buffering effect, and it is convenient for the binding head to pass through the opening of the pressing plate for binding. Finally, the second rubber pad can also use its own softness to reduce the extrusion force during contact and provide a protection effect. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments; based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] As Figures 1 - 5 shown, the present utility model includes a machine table 1, a frame 2 is installed on the top of the machine table 1, a lifting plate 4 is installed on the frame 2 through a hydraulic rod 3, a binding head 6 and a positioning assembly 5 are installed at the bottom of the lifting plate 4, the positioning assembly 5 includes rack plates 51 fixed on both sides of the bottom of the lifting plate 4, the rack plates 51 are engaged with gears 52, the gears 52 are rotatably connected to one side of a vertical plate 53, the vertical plate 53 is fixed on the top of the machine table 1, a lead screw 54 is installed on the other side of the gear 52 docking the vertical plate 53, a moving rod 55 is installed outside the lead screw 54, a clamping plate 56 is docked on one side of the moving rod 55, a sleeve rod 57 is fixed on one side of the clamping plate 56, and the sleeve rod 57 is sleeved outside a cross bar 58 fixed on one side of the vertical plate 53.

[0025] As described above, by designing the positioning component 5, when sealing and binding the carton, place the carton on the top of the machine table 1, then start the hydraulic rod 3 on the rack 2 to lower the lifting plate 4, so that the binding head 6 and the rack plate 51 descend together. When the rack plate 51 moves downward, the gear 52 rotates, and then the lead screw 54 rotates to drive the moving rod 55 to move. At this time, the moving rod 55 will push the clamping plate 56, and the clamping plate 56 moves stably under the sliding fit of the four-way sleeve rod 57 and the cross bar 58. Finally, when the binding head 6 descends to the binding position, the two clamping plates 56 complete the clamping, thus improving the working stability. In this way, during batch processing, it is not necessary to fix the carton first and then seal it, and there is no need for manual control of clamping, which effectively improves the processing efficiency and reduces the processing time. It should be noted that sliding plates are provided at the upper and lower ends of the moving rod 55, and the sliding plates slide outside the straight rod fixed on one side of the vertical plate 53, so as to limit the moving rod 55. This is an existing limiting technical means, so it is not mentioned and elaborated in the claims.

[0026] One side of the moving rod 55 is butted against the clamping plate 56 through a buffer spring A59, and a rubber pad 510 is bonded to the clamping surface of the clamping plate 56.

[0027] As described above, the rubber pad 510 can effectively reduce the damage to the carton caused by extrusion, and the buffer spring A59 has a good buffering effect, further reducing the damage that the extrusion force during clamping may cause to the carton. At the same time, it is difficult for traditional technologies to make the binding head 6 just reach the working position when the clamping plate 56 completes clamping, and the carton must be clamped first due to position reasons in order to make the binding position correspond to the binding head 6. Therefore, through the deformation design of the buffer spring A59, after the clamping plate 56 first contacts the carton and clamps it, the binding head 6 descends a little more distance to reach the binding position, which is very useful.

[0028] The machine table 1 is provided with a through hole at one side position of the vertical plate 53, and the rack plate 51 passes through the through hole when descending during the working process.

[0029] As described above, such a through hole facilitates the rack plate 51 to pass through the machine table 1 when descending, leaving a moving space for the rack plate 51.

[0030] A pressing plate assembly 7 is provided on the lifting plate 4. The pressing plate assembly 7 includes a pressing plate 71. Four sliding rods 72 passing through the lifting plate 4 are fixed to the top of the pressing plate 71. A buffer spring B73 is connected between the sliding rods 72 and the lifting plate 4. An opening for the binding head 6 to pass through is provided on the pressing plate 71. A rubber pad 74 is bonded to the bottom surface of the pressing plate 71, and the area of the rubber pad 74 is the same as the bottom surface area of the pressing plate 71.

[0031] As described above, through the pressing plate assembly 7, when the lifting plate 4 descends, the pressing plate 71 will first contact the top of the carton, thereby flattening the top surface of the carton. The buffer spring B73 and the sliding rod 72 can provide a buffering effect and facilitate the binding head 6 to pass through the opening of the pressing plate 71 for binding. Finally, the second rubber pad 74 can also utilize its own softness to reduce the extrusion force during contact and provide a protection effect.

[0032] There are openings at two positions between the two clamping plates 56 on the machine table 1, and a row of rolling rollers 8 are rotatably connected to the inner wall of the opening. There is a stacking plate 9 fixed on the machine table 1, and the stacking plate 9 is located on one side of the rolling rollers 8.

[0033] As described above, through the stacking plate 9 and the rolling rollers 8, the rolling rollers 8 facilitate the movement of the carton when placing and taking it. And when placing the carton, by pushing, one side of the carton is made to fit against the stacking plate 9. At this time, the carton is in a proper position, and then through clamping, the carton can be in a proper position.

[0034] Working principle: When placing the carton, the carton is placed on the rolling rollers 8, and then by pushing, one side of the carton is made to fit against the stacking plate 9. Then, the hydraulic rod 3 on the rack 2 is started to make the lifting plate 4 descend, so that the binding head 6 and the rack plate 51 descend together. When the rack plate 51 moves downward, the gear 52 rotates, and then the lead screw 54 rotates to drive the moving rod 55 to move. At this time, the moving rod 55 will push the clamping plate 56, and the clamping plate 56 moves stably under the sliding cooperation of the four sleeve rods 57 and the cross bar 58. Finally, when the binding head 6 descends to the binding position, the two clamping plates 56 complete the clamping, and the pressing plate 71 will first contact the top of the carton with the binding head 6, thereby flattening the top surface of the carton. At the same time, the buffer spring B73 and the sliding rod 72 can provide a buffering effect and facilitate the binding head 6 to pass through the opening of the pressing plate 71 for binding.
