Description

Technical Field

[0001] This utility model relates to the field of material sealing equipment, and more specifically to a carton closing mechanism after material is packed. Background Technology

[0002] In the existing roll packaging film production line's boxing and sealing process, the relevant equipment can only perform the boxing function of roll materials, that is, feeding the roll packaging film into the carton via a conveyor mechanism. For example... Figure 1 As shown, because the inner and outer flaps often fold down to below the horizontal level, the existing equipment cannot complete the automatic closing action of the carton.

[0003] Due to this technological limitation, existing production lines rely on manual labor to complete subsequent key processes: operators must manually fold and seal the inner flaps of the cartons, then fold and cover the outer flaps to ensure complete closure, before sealing the cartons with tape, either manually or using equipment. This method results in high labor costs, low operational efficiency, and poor packaging consistency. Utility Model Content

[0004] To solve the above problems, this utility model provides the following technical solution:

[0005] A carton closing mechanism after material packing includes a pre-pressing module, a capping module, and a conveyor line. The carton is conveyed sequentially along the direction of the pre-pressing module and the capping module via the conveyor line. The pre-pressing module flips the inner flap of the carton between the two outer flaps and tilts it inward. The pre-pressing module flips the outer flaps above the horizontal line. The capping module presses the inner flap of the carton to a horizontal state and presses the outer flaps to fit against the inner flap.

[0006] The present invention is further configured such that: the pre-compression module includes a first frame, a frame is movably connected to the first frame in the vertical direction, two sliding arms are movably connected to the frame in the horizontal direction, the two sliding arms are initially located on the outer side of the inner flap, and two sliding rods are movably connected to the sliding arms in the length direction, the sliding rods extend toward the adjacent sliding arms, and the two sliding rods are initially located on the outer side of the outer flap.

[0007] The present invention is further configured such that: a pre-compression cylinder is horizontally arranged on one side of each of the two sliding arms facing each other, and the output shafts of the pre-compression cylinders on the two sliding arms extend outwards towards each other.

[0008] The present invention is further configured such that: the slide rod is cylindrical, and a rubber head is provided at the end of the output shaft of the pre-compression cylinder.

[0009] The present invention is further configured such that: the capping module includes a second frame disposed above the conveyor line, a pressure plate is movably connected to the second frame in the vertical direction, and pressure arms are respectively hinged on the second frame and located on both sides of the pressure plate. When the two pressure arms are in the initial state, they are respectively located outside the outer flap. When the pressure arms rotate downward, they drive the outer flap to rotate inward, and when the outer flap rotates to the horizontal state, it is tangent to the rotation path of the pressure arms.

[0010] The present invention is further configured such that: a pressing drive cylinder is provided on the second frame, the output shaft of the pressing drive cylinder extends and retracts vertically downward and is fixed to the pressure plate, and two rotary drive cylinders are rotatably connected on the second frame, the output shafts of the two rotary drive cylinders are respectively rotatably connected to the pressure arm, and when the output shaft of the rotary drive cylinder extends and retracts, it drives the pressure arm to rotate around its hinge axis.

[0011] The present invention is further configured such that: the end of the pressure arm is provided with an abutment rod, both the pressure plate and the abutment rod extend along the conveying direction of the conveyor line, and both ends of the abutment rod have ball heads.

[0012] The present invention is further configured such that: the capping module also includes two clamping plates movably disposed on the conveyor line, the two clamping plates being located on both sides of the conveying direction of the conveyor line, the two clamping plates moving towards each other in a direction perpendicular to the conveying direction of the conveyor line and clamping the side wall of the carton.

[0013] Compared with the prior art, the present invention has at least the following advantages:

[0014] 1. Since the flaps of the carton are often below the horizontal line (tilting downwards on the outside), the carton closing operation is divided into two steps: pre-pressing and pressing. This completes the fully automated operation from the inner flap pre-flipping inward, the outer flap lifting, to the inner flap horizontal pressing and the outer flap precise fitting. No manual intervention is required for the closing action. This solves the defects of high reliance on manual labor and low operating efficiency in existing production lines. It matches the cycle time of automated production lines and greatly improves the overall production capacity.

[0015] 2. The frame is lifted from bottom to top, and the sliding arm and sliding rod lift the inner and outer flaps upward respectively. A pre-compression cylinder is further provided. After the inner flap is lifted upward, the pre-compression cylinder extends to press the inner flap downward, so that the inner flap tilts inward at a greater angle, making it easier for the subsequent pressure plate to press down directly.

[0016] 3. The slide bar is cylindrical, and a rubber head is also provided at the end of the output shaft of the pre-pressure cylinder to prevent damage to the outer side when sliding against the inner and outer covers, making the flipping action smoother and more gentle.

[0017] 4. The clamping plate positions and clamps the side wall of the carton before pressing to prevent the carton from shifting and to ensure that the carton and the subsequent adhesive tape equipment are in a consistent position, resulting in a more consistent sealing effect.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can typically be arranged and designed in various different configurations.

[0032] like Figure 2 As shown, a carton closing mechanism after material packing includes a pre-compression module 1, a capping module 2, and a conveyor line 3. The carton 4 is conveyed sequentially along the pre-compression module 1 and the capping module 2 via the conveyor line 3, forming a continuous production line. The pre-compression module 1 flips the inner flap 401 of the carton 4 between the two outer flaps 402 and tilts it inward, flipping the outer flaps 402 above the horizontal line. After the carton 4 undergoes pre-compression to change the angle between the inner flap 401 and the outer flaps 402, the capping module 2 can directly press the inner flap 401 of the carton 4 to a horizontal state and press the outer flaps 402 to fit against the inner flap 401. Subsequently, tape is applied along the gaps of the outer flaps 402 by an adhesive tape applicator to complete the sealing process, or the tape can be applied manually.

[0033] The conveyor line 3 adopts a synchronous chain conveyor structure. In this embodiment, the feed end and the discharge end of the conveyor line 3 need to turn vertically. Therefore, transmission rollers are set at the feed end and the discharge end. The synchronous chain is set between the transmission rollers in a lifting module. When the material enters the pre-compression module 1, the synchronous chain rises above the transmission rollers and is flush with the synchronous chain of the capping module 2.

[0034] like Figures 3 to 6 As shown, the pre-compression module 1 specifically includes a first frame 101. A frame 102 is movably connected to the first frame 101 in the vertical direction. The frame 102 is a rectangular frame, and its four corners are slidably connected to the four columns of the first frame 101. The frame 102 can be driven by a motor, a synchronous sprocket, a synchronous chain, or other existing driving methods. Two sliding arms 103 are movably connected to the frame 102 in the horizontal direction. Two sliding rods 104 are movably connected to the sliding arms 103 in the length direction. The sliding rods 104 extend towards the adjacent sliding arms 103, that is, the sliding rods 104 are perpendicular to the sliding arms 103. The sliding arms 103 are used to contact the inner flap 401, and the sliding rods 104 are used to contact the outer flap 402.

[0035] The frame 102 has two parallel first guide rails 107 arranged horizontally. The two ends of the two sliding arms 103 are slidably connected to the first guide rails 107 via sliding seats. The bottom of the sliding arms 103 has two second guide rails 108 arranged along its length. The two sliding rods 104 are slidably connected to the second guide rails 108 via sliding seats. The sliding seats of the sliding arms 103 and the sliding rods 104 can be driven by a motor driving a synchronous belt to move, or by a motor driving a screw to rotate, or by other existing driving methods.

[0036] Furthermore, a pre-compression cylinder 105 is horizontally arranged on one side of the two sliding arms 103 facing each other, and the output shafts of the pre-compression cylinders 105 on the two sliding arms 103 extend towards each other, that is, extend into the sliding arms 103.

[0037] When the carton 4 enters the pre-compression module 1, the two sliding arms 103 are located outside the inner flap 401, and the two sliding rods 104 are located outside the outer flap 402. At this time, the frame 102 descends as a whole, the sliding arms 103 move inward to below the inner flap 401, and the frame 102 moves upward a certain distance, so that the inner flap 401 is pushed above the horizontal line by the sliding arms 103. The pre-compression cylinder 105 extends and pushes the inner flap 401 inward to a near-horizontal state. Then the sliding rods 104 move inward to below the outer flap 402, and the frame 102 moves upward as a whole, so that the outer flap 402 is pushed above the horizontal line by the sliding rods 104.

[0038] like Figure 7 As shown, after the carton 4 passes through the pre-compression module 1, the inner flap 401 is folded between the inner flap 402 and tilted inward at a large angle, and the outer flap 402 is flipped up to above the horizontal line.

[0039] In this embodiment, the slide bar 104 is cylindrical, and the output shaft end of the pre-compression cylinder 105 is provided with a hemispherical rubber head 106, so that when the slide bar 104 and the pre-compression cylinder 105 slide together with the outer flap 402 and the inner flap 401, the outer side of the carton 4 will not be damaged, and the sliding will be smoother and more gentle.

[0040] like Figures 8 to 11 As shown, the capping module 2 specifically includes a second frame 201 set above the conveyor line 3. A pressure plate 202 is movably connected to the second frame 201 in the vertical direction. Pressure arms 203 are hinged to the second frame 201 on both sides of the pressure plate 202. When the two pressure arms 203 are in the initial state, they are located on the outside of the outer flap 402. When the pressure arms 203 rotate downward, they drive the outer flap 402 to rotate inward. When the outer flap 402 rotates to the horizontal state, it is tangent to the rotation path of the pressure arms 203. That is, when the pressure arms 203 rotate downward to the horizontal state, they just press the outer flap 402 to the horizontal state.

[0041] The driving method is as follows: a pressing drive cylinder 204 is installed on the second frame 201. The output shaft of the pressing drive cylinder 204 extends and retracts vertically downwards and is fixed to the pressure plate 202, thereby driving the pressure plate 202 to rise and fall by extending and retracting the output shaft of the pressing drive cylinder 204. Two rotary drive cylinders 205 are rotatably connected to the second frame 201. The output shafts of the two rotary drive cylinders 205 are respectively rotatably connected to the pressure arm 203, thereby driving the pressure arm 203 to rotate around its hinge axis when the output shaft of the rotary drive cylinder 205 extends and retracts.

[0042] The end of the pressure arm 203 is provided with an abutment rod 206. Both the pressure plate 202 and the abutment rod 206 extend along the conveying direction of the conveyor line 3, thereby increasing the contact area with the carton 4 and making it easier to rotate the inner flap 401 and the outer flap 402. The abutment rod 206 has ball ends at both ends, thereby preventing the ends of the abutment rod 206 from scratching the carton 4 when it moves.

[0043] The capping module 2 also includes two clamping plates 207 movably mounted on the conveyor line 3. The two clamping plates 207 are located on both sides of the conveying direction of the conveyor line 3, and move towards each other in a direction perpendicular to the conveying direction of the conveyor line 3, thereby clamping the side wall of the carton 4. A guide rod 208 is provided in the conveying direction perpendicular to the conveying direction. The bottom of the clamping plate 207 is slidably connected to the guide rod 208. By providing two clamping cylinders 209, the output shafts of the two clamping cylinders 209 are fixed to the two clamping plates 207, so that the clamping plates 207 slide on the guide rod 208 by the extension and retraction of the clamping cylinders 209.

[0044] After passing through the pre-pressing module 1, the carton 4 enters the capping module 2. The clamping plates 207 on both sides move toward the carton 4 and clamp onto the side wall of the carton 4. The pressing drive cylinder 204 drives the pressure plate 202 to descend, pressing the two inner flaps 401 down to a horizontal state. Then, the two rotary drive cylinders 205 drive the two pressure arms 203 to rotate downwards, pressing the two outer flaps 402 down onto the inner flaps 401. Then, the clamping plate 207 moves outwards to release the carton 4. The carton 4 continues to be conveyed forward by the conveyor line 3 while the pressure plate 202 and the pressure arm 203 are in contact. The sealing operation is completed by the tape application mechanism or by manually applying tape.

Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.
