Description

Technical Field

[0001] This utility model relates to the field of sealing machine technology, and in particular to a carton sealing machine. Background Technology

[0002] A carton sealing machine is an automatic sealing device for cartons. It automatically seals the lids of cartons with tape, improving packaging efficiency, reducing manual labor, and ensuring the quality and consistency of carton sealing. During production, due to the size limitations of the sealing machine itself, the conveyor platform behind it is relatively short. If cartons are not promptly transferred after passing through the sealing machine, they may be pushed to the ground by subsequent cartons, requiring production staff to pick them up and place them back on a pallet. The cartons may also break when they fall to the ground, and the products inside may collide with them.

[0003] For example, Chinese utility model patent CN220181853U discloses a carton sealing machine, relating to the technical field of carton sealing equipment. The carton sealing machine includes a base and a roller conveyor belt mounted on the base; it also includes a pressure plate, a sealing mechanism, a lifting structure, and a guiding mechanism; the lifting structure includes a vertical rod, a guide rail, a slider, and a cylinder; the vertical rod is vertically fixed to both sides of the base; the guide rail is vertically fixed to the side of the vertical rod; the slider slides on the guide rail; the cylinder is vertically fixed to both sides of the base; the pressure plate is fixed to the sliders on both sides of the base, and the drive rod ends of the cylinders on both sides of the base are respectively fixedly connected to both sides of the pressure plate; the sealing mechanism is mounted on the pressure plate; the guiding mechanism includes a first bidirectional lead screw, a second bidirectional lead screw, an adjusting block, a connecting plate, a vertical plate, a top plate, a guide block, and a motor.

[0004] The sealing machine in this solution can be adapted to sealing various sizes of cartons, but the original platform behind it is also relatively short. Directly lengthening the platform would result in an excessively large sealing machine, making it difficult in many cases to accommodate the support platform that matches its height at the rear for sealing the carton after sealing. Therefore, the problem of the sealed carton falling to the ground still exists. Utility Model Content

[0005] In view of the shortcomings in the above-mentioned background technology, this utility model proposes a carton sealing machine, which solves the problem that the carton is easy to fall off after sealing due to the lack of a load-bearing structure in the prior art.

[0006] The technical solution of this utility model is implemented as follows: a carton sealing machine includes a sealing machine body, the sealing machine body is mounted on a support, an extension frame is slidably mounted on the support, a roller conveying structure is mounted on the extension frame, a support component is mounted at the bottom of the extension frame, and a locking component is provided between the extension frame and the support.

[0007] Preferably, the bracket has symmetrical sliding grooves on both sides, and the extension frame slides in conjunction with the sliding grooves.

[0008] Preferably, the roller conveying structure includes several rollers, each roller having a bearing fixedly mounted at both ends, each bearing being connected to a support shaft, and the end of the support shaft cooperating with an extension frame.

[0009] Preferably, the extension frame is provided with symmetrical horizontal sliding grooves, and grooves are provided at equal intervals on the horizontal sliding grooves. The number of grooves corresponds to the number of rollers, and the support shaft can slide in the horizontal sliding grooves and can cooperate with the grooves.

[0010] Preferably, the support assembly includes a support leg fixedly disposed at the bottom of the extension frame, and a reinforcing angle steel is provided on the outer side of the connection between the extension frame and the support leg.

[0011] Preferably, the locking assembly includes a support base fixedly mounted on the bracket, a pin slidably mounted on the support base, and a through hole between the bracket and the extension frame to allow the pin to pass through. A spring is provided between the pin and the support base.

[0012] Preferably, the support frame is rotatably equipped with several rear support rollers. Both the support frame and the legs are equipped with casters at their bottom. The extension frame has a blocking block at its end.

[0013] The beneficial effects of this utility model are:

[0014] By incorporating a support frame, the existing sealing machine body can be supported. An extension frame, slidably mounted on the support, can extend during use and retract when not in use, reducing space occupation. A roller conveyor structure can support the sealed cartons during use, preventing them from falling. A locking component can lock the extension frame after its position is adjusted, improving operational stability. This invention has a reliable structure and can be retrofitted to existing sealing machines without requiring a matching support structure, thus avoiding the problem of sealed cartons easily falling off in existing technologies.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1 , 2 As shown in Embodiment 1, a carton sealing machine includes a sealing machine body 1, which is mounted on a support 2. The support supports the existing sealing machine body and provides a foundation for the installation and fixing of other components. In this embodiment, the sealing machine body and support can be selected from existing conventional sealing machines, such as the carton sealing machine in Chinese Utility Model Publication No. CN220181853U. In this embodiment, an extension frame 3 is slidably provided on the support 2, which can extend in use and retract in non-use, reducing space occupation. The extension frame 3 is provided with a roller conveyor structure 4, which can support the sealed carton in use and prevent it from falling. A support component 5 is provided at the bottom of the extension frame 3, and a locking component 6 is provided between the extension frame 3 and the support 2. The locking component can lock the extension frame after its position is adjusted, improving the stability of use. This utility model has a reliable structure and can be used by retrofitting existing sealing machines without the need for on-site adaptation of a supporting structure, avoiding the problem of sealed cartons easily falling off in the prior art.

[0025] Specifically, in this embodiment, a plurality of rear receiving rollers 22 are rotatably mounted on the support 2 to provide rolling support, facilitating the movement of the carton after the sealing machine body has sealed. Additionally, symmetrical sliding grooves 21 are provided on both sides of the support 2, and the extension frame 3 slides in cooperation with the sliding grooves 21. Specifically, in this embodiment, the sliding grooves 21 can be selected from two symmetrical channel steels on the support, with the openings of the two channel steels facing each other and fixed to the support by welding or bolts. The two channel steels are positioned below the rear receiving rollers to avoid affecting their rotation, and are located on both sides of the sealing machine body.

[0026] Example 2, a carton sealing machine, such as Figure 3 , 6 As shown, based on Embodiment 1, the roller conveyor structure 4 includes several rollers 41. Bearings 42 are fixedly mounted at both ends of each roller 41, and each bearing 42 is connected to a support shaft 43. The end of the support shaft 43 cooperates with the extension frame 3. In this embodiment, the rollers 41 are fixed to the outer ends of the bearings 42, and the support shaft 43 is fixed to the inner ring of the bearings 42, thereby enabling the rollers 41 to rotate relative to the support shaft 43.

[0027] In this embodiment, the extension frame is a U-shaped frame, the sealing machine body corresponds to the opening of the U-shaped frame, the extension frame 3 is symmetrically provided with horizontal slide grooves 31, and the horizontal slide grooves 31 are provided with grooves 32 at equal intervals. The number of grooves 32 corresponds to the number of rollers 41. The support shaft 43 can slide in the horizontal slide grooves 31 and can cooperate with the grooves 32.

[0028] like Figure 3 , 5 As shown, under normal use, the support shaft 43 of the roller 41 corresponds one-to-one with the groove 32. Under the action of gravity, the groove 32 locks the support shaft 43 in the horizontal direction, so that several rollers 41 can be used to support the cartons that move onto them and can roll as they move. When it is necessary to retract the extension frame 3, due to the space occupied by the sealing machine body 1 at the opening of the extension frame 3, if the extension frame 3 is long, the space provided by the horizontal slide 31 can be used to move the rollers 41 near one end of the sealing machine body 1 side by side to the end away from the sealing machine body 1, reducing the space occupied and avoiding interference with the sealing machine body 1 when retracting.

[0029] Example 3: A carton sealing machine, based on Example 2, wherein the support assembly 5 includes a leg 51 fixedly mounted at the bottom of the extension frame 3, and a reinforcing angle steel 52 is provided on the outer side of the connection between the extension frame 3 and the leg 51. In this example, two legs 51 are provided, both of which are vertically fixed at the front corner of the extension frame 3. The reinforcing angle steel 52 is welded and fixed at the corner of the extension frame 3, fitting against the outer wall of the leg 51 and welded and fixed to the outer wall of the leg 51, thereby reinforcing the connection between the leg 51 and the extension frame 3.

[0030] In addition, in this embodiment, as Figure 4 As shown, the locking component 6 includes a support base 61 fixedly mounted on the bracket 2, a pin 62 slidably mounted on the support base 61, and a through hole 63 between the bracket 2 and the extension frame 3 to allow the pin 62 to pass through. Additionally, to achieve automatic pin positioning, a spring 64 is provided between the pin 62 and the support base 61. In this embodiment, the support base is a U-shaped seat, welded and fixed to a groove 21 on the bracket. The support base and the groove 21 have through holes to allow the pin to pass through. The pin slides vertically in the through hole, and a stop portion 65 is fixedly mounted on the pin. A spring is located on the pin above the stop portion, between the stop portion and the fixed base. When no adjustment is needed, the stop portion is pressed against the surface of the groove under the support of the spring, while the lower end of the pin inserts into the through hole of the extension frame.

[0031] As a further specific implementation, a plurality of through holes 21 are provided at equal intervals on the extension frame 3. This allows the extension frame 3 to be locked in position using the engagement of the pin 62 and the through holes 63, regardless of the different extension lengths of the extension frame 3 relative to the support 2, thus meeting the needs of different extension length application scenarios. Furthermore, a handle is provided at the top of the pin for easy gripping. When it is necessary to adjust the position of the extension frame on the slide rail, pulling the handle separates the lower end of the pin from the through hole of the extension frame, thereby unlocking the extension frame and enabling position adjustment.

[0032] As a further optional implementation, in this embodiment, casters 23 are provided at the bottom of both the bracket 2 and the support leg 51, so as to facilitate the overall movement of the equipment and provide follow-up support for the extension frame as it extends outward or retracts inward.

[0033] In addition, in this embodiment, to prevent cartons from falling from the front end when there are too many on the extension frame, a blocking block 33 is provided at the end of the extension frame 3 to block them. In this embodiment, a support block is welded to the front end of the extension frame, and the blocking block is welded and fixed to the support block. At the same time, to prevent the blocking block from affecting the sealing of the cartons when the extension frame is retracted, the height from the top of the blocking block to the upper surface of the extension frame is less than the vertical height from the upper surface of the extension frame to the uppermost end of the rear receiving roller 22, so as to avoid affecting the movement of the cartons when retracting. Thus, the sealing machine body can still complete the sealing operation normally when the extension frame is retracted, meeting the needs of more usage scenarios.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
