[0002] On plum packaging production lines, the sealing process of the packaging boxes is crucial. Traditional plum packaging box sealing methods have several drawbacks. On the one hand, the sealing film adjustment is not precise enough, making it difficult to accurately align the pattern on the sealing film with the packaging box, affecting the packaging's aesthetics. It also easily leads to waste of sealing film material, increasing production costs. On the other hand, inconsistent sealing quality and imprecise heating control can result in weak seals or defects at the seal, affecting the product's airtightness and freshness preservation. Furthermore, existing sealing equipment lacks stability during operation; collisions and uneven stress between components can easily cause equipment damage, reducing its lifespan and increasing maintenance costs. For example, while some existing patented packaging sealing equipment possesses basic sealing functions, it has shortcomings in sealing film adjustment and equipment stability.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0026] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0027] like Figures 1 to 5 As shown, the automatic sealing and edge-pressing device for plum packaging boxes includes a body assembly 100, a sealing film roll assembly 200, a sealing assembly 300, and a buffer assembly 400.

[0028] like Figure 2 As shown, the body assembly 100 includes a base 101, a rotating frame 102, a fastening seat 104, and an electric cylinder 105. The two ends of the rotating frame 102 are respectively connected to the base 101 and the fastening seat 104, and are used to support the fastening seat 104 relative to the base 101. The electric cylinder 105 is rotatably mounted on the base 101, and the output end of the electric cylinder 105 is rotatably mounted in the middle of the fastening seat 104. The electric cylinder 105 is used to control the fastening movement of the fastening seat 104. The sealing assembly 300 and the buffer assembly 400 are disposed inside the fastening seat 104.

[0029] Specifically, the fastening seat 104 is provided with an upper cover plate 106 and a lower cover plate 107. The fastening seat 104 is connected on both sides and is sealed by the upper cover plate 106 and the lower cover plate 107. In use, the electric cylinder 105 is started by controlling the electric control system. The output end of the electric cylinder 105 pushes or pulls the middle part of the fastening seat 104, so that the fastening seat 104 rotates around the axis of the upper end of the rotating frame 102, thereby realizing the fastening and disengagement with the base 101.

[0030] like Figure 1 and Figure 2 As shown, the sealing film roll assembly 200 includes a sealing film roll 202 and a sleeve 204. The sleeve 204 and the sealing film roll 202 are respectively disposed at the front and rear ends of the base 101. The opening end of the film on the sealing film roll 202 is connected to the sleeve 204. The precise movement of the film is controlled by the rotation of the sealing film roll 202 and the sleeve 204 themselves.

[0031] In use, pull out the film from the sealing film roll 202, cover the sealed packaging box, and then contact the sleeve 204 to fix it on the sleeve 204. By controlling the sleeve 204 or the sealing film roll 202 to rotate, the front and back of the sealing film can be adjusted to align the pattern or save sealing film material, reduce the distance between two seals, and reduce material waste.

[0032] like Figure 1 and Figure 2As shown, the sealing film roll assembly 200 includes a rear adjustment plate 203 and a support rod 201. The support rod 201 is fixedly installed at the rear end of the base 101, and the rear adjustment plate 203 is rotatably installed on the support rod 201. The rear adjustment plate 203 is provided with a plurality of protrusions. The rear adjustment plate 203 is inserted into the through groove of the sealing film roll 202 and forms a tight connection with the sealing film roll 202 through the protrusions, thereby controlling the rotation of the sealing film roll 202.

[0033] like Figure 1 and Figure 2 As shown, the sealing film roll assembly 200 includes a front adjusting plate 205, which is rotatably mounted on the base 101. A sleeve 204 is fitted onto the front adjusting plate 205, and the front adjusting plate 205 is provided with a plurality of protrusions. The front adjusting plate 205 is inserted into the through groove of the sleeve 204, and forms a tight connection with the sealing film roll 202 through the protrusions, thereby controlling the rotation of the sealing film roll 202.

[0034] Specifically, the sealing film roll 202 and the rear adjusting plate 203 are supported by the support rod 201, and the sleeve 204 is supported by the front adjusting plate 205. During use, the operator manually controls the rotation of the rear adjusting plate 203. The friction between the multiple protrusions and the sealing film roll 202 drives the sealing film roll 202 to rotate, thereby pulling the sealing film towards the rear end. Similarly, the front adjusting plate 205 moves the sealing film at the front end.

[0035] like Figures 3 to 5 As shown, the sealing assembly 300 includes a mounting bracket 301, an electric heater 302, and a heating plate 303. Two mounting brackets 301 are fixedly provided on the fastening seat 104. The mounting brackets 301 are provided with grooves for heat dissipation. The electric heater 302 is mounted on the mounting bracket 301 and is connected to the heating plate 303 through wires and limiting members.

[0036] Specifically, two mounting brackets 301 form mounting positions for the electric heater 302. The mounting brackets 301 are bolted to the fastening seat 104, and the electric heater 302 is also bolted to the mounting brackets 301, creating a gap between the electric heater 302 and the inner wall of the fastening seat 104 to facilitate heat dissipation. Furthermore, the upper cover plate 106 is also provided with vent holes for heat dissipation.

[0037] In use, the heating wire inside the heating plate 303 is heated by the electric heater 302 and the wire, thereby applying heat to the lower end surface of the heating plate 303 for subsequent sealing of the packaging box. The heating plate 303 is provided with a rectangular frame metal sheet located on the outside of the sealing area. This metal sheet also receives heat, thereby cutting the outside of the sealing area during sealing, so that the sealing film is separated from the packaging box, thus achieving the cutting of the sealing film.

[0038] like Figures 3 to 5 As shown, the limiting components include a limiting slide rod 304 and a limiting spring 305. The limiting slide rod 304 is fixedly mounted on the electric heater 302, and the limiting spring 305 is sleeved on the limiting slide rod 304. The limiting spring 305 is used to buffer the vertical movement of the electric heater 302. The two ends of the limiting spring 305 are fixedly connected to the heating plate 303 and the electric heater 302, respectively. Each electric heater 302 is provided with four limiting components, and two electric heaters 302 are connected to the heating plate 303, thus allowing two packaging boxes to be sealed simultaneously.

[0039] In use, when the fastening seat 104 is close to the base 101, the heating plate 303 and the upper pressure film frame 108 on the side of the fastening seat 104 near the rotating frame 102 will first contact the packaging box. After the upper pressure film frame 108 contacts the packaging box, it slides on the fastening seat 104. Then, after the heating plate 303 contacts the packaging box, it slides upward on the upper pressure film frame 108. As a result, the heating plate 303 slides on the limiting slide bar 304 and compresses the limiting spring 305. Because the distance that the heating plate 303 can move is limited and cannot be too large, the limiting spring 305 is needed for buffering and limiting to avoid excessive movement of the heating plate 303.

[0040] like Figure 2 As shown, the body assembly 100 includes an upper pressure film frame 108 and a lower pressure film frame 109. The upper pressure film frame 108 is mounted on the fastening seat 104, and the lower pressure film frame 109 is fixedly mounted on the base 101. The upper pressure film frame 108 and the lower pressure film frame 109 correspond in size and position. Each heating plate 303 is fitted with an upper pressure film frame 108. The upper pressure film frame 108 is slidably mounted on the lower cover plate 107.

[0041] Specifically, when the fastening seat 104 rotates around the axis of the rotating frame 102 via the connecting plate 103, the upper pressure film frame 108 on the fastening seat 104 gradually approaches the lower pressure film frame 109. The upper pressure film frame 108 on the side closer to the rotating frame 102 will contact the lower pressure film frame 109 first. When the upper pressure film frame 108 contacts the lower pressure film frame 109, the other one has not yet contacted. Therefore, the upper pressure film frame 108 needs to move a certain distance to wait for the other upper pressure film frame 108 to contact the lower pressure film frame 109. After both upper pressure film frames 108 have contacted the lower pressure film frame 109, they move a certain distance again to form a tight connection between the two upper pressure film frames 108 and the lower pressure film frame 109. Then, the staff can carry out the sealing work of the packaging box.

[0042] like Figures 3 to 5As shown, the buffer assembly 400 includes a limiting frame 401, an inner sliding plate 402, and an outer sliding plate 403. A limiting frame 401 is fixedly installed at both ends of the upper pressure film frame 108. An inner sliding plate 402 is fixedly installed on each limiting frame 401, and an outer sliding plate 403 is slidably installed on each inner sliding plate 402. The outer sliding plate 403 is fixedly installed on the fastening seat 104.

[0043] Specifically, when the upper pressure film frame 108 contacts the lower pressure film frame 109, it is blocked by the lower pressure film frame 109 and cannot move further downward. As a result, the upper pressure film frame 108 drives the limiting frame 401 to push the inner slide plate 402 to slide on the outer slide plate 403, thereby changing the position of the upper pressure film frame 108 to adapt to the rotation of the fastening seat 104, and waiting for the two upper pressure film frames 108 to make complete contact with the lower pressure film frame 109.

[0044] like Figures 3 to 5 As shown, the buffer assembly 400 includes a buffer member and a stabilizing plate 407. The buffer member includes a telescopic rod 404, a buffer spring 405, and a fixing plate 406. The fixing plate 406 is fixedly installed on the fastening seat 104. The two ends of the buffer spring 405 are fixedly connected to the fixing plate 406 and the limiting frame 401, respectively. The buffer spring 405 is sleeved on the limiting frame 401. The two ends of the buffer spring 405 are fixedly connected to the fixing plate 406 and the telescopic rod 404, respectively. The two ends of the stabilizing plate 407 are fixedly connected to a buffer member, and the stabilizing plate 407 is used to stabilize the end of the buffer member away from the fastening seat 104.

[0045] Specifically, when the limiting frame 401 moves, the limiting frame 401 pushes the buffer spring 405 to contract and squeeze the buffer spring 405. The elastic force of the buffer spring 405 reacts on the fixed plate 406. When the elastic force reaches a certain level and after long-term and repeated use, the upper cover plate 106 may break. Therefore, it is necessary to stabilize the two fixed plates 406 with the stabilizing plate 407 to increase their structural strength and improve their service life.

[0046] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
