A reciprocating packaging machine with a weighing mechanism

Abstract

This utility model relates to the field of packaging machine technology, specifically a reciprocating packaging machine with a weighing mechanism. It includes a packaging table, a weighing platform fixedly mounted on the top of the packaging table, baffles fixedly mounted at both ends of the weighing platform, and a reciprocating mechanism mounted above the weighing platform. By installing a tape pressing component at one end of the support arm of the packaging mechanism, during the process of the servo motor driving the tape roll to roll left and right for pasting, the pressing roller in the tape pressing component can be synchronously driven to roll synchronously. A return spring is connected between the side of the movable pressure rod near the fixed plate and the bottom side of the support arm. The horizontal installation height of the pressing roller is lower than that of the tape roll, so that the pressing roller closely follows the tape roll, providing elastic pressing of the tape to enhance the adhesion between the tape and the surface of the packaging box. This avoids the problem of easy breakage of the box during transportation due to weak adhesion, improves production quality, and reduces the product damage rate during transportation.

Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology, specifically a reciprocating packaging machine with a weighing mechanism. Background Technology

[0002] In the packaging industry, packaging quality and production efficiency directly impact enterprise profitability. Traditional packaging machines often suffer from issues such as weak tape adhesion and high manual intervention, leading to seal cracks or damage to boxes during transport. This not only affects product delivery quality but also increases rework costs. Furthermore, the lack of integrated weighing functionality necessitates the use of additional weighing equipment, which occupies space and disrupts the continuity of the packaging process. Current technologies separate packaging and weighing processes, resulting in frequent manual handling, low production efficiency, and an inability to meet the demands of modern industrial mass production. Therefore, there is an urgent need to develop a high-efficiency packaging device that integrates weighing and automated packaging to address the shortcomings of traditional packaging machines and improve packaging automation and production quality.

[0003] A packaging machine with a weighing structure, as disclosed in authorization announcement number CN220640332U, includes a base. A support frame is fixedly installed on the upper end of the base, and a packaging device is provided at the lower end of the support frame. The packaging device includes a reciprocating screw, a driven wheel, a threaded block, a tape, a drive motor, a drive wheel, and a belt. The upper end of the reciprocating screw is rotatably connected to the support frame, and the driven wheel is fixedly installed on the lower end of the reciprocating screw. The threaded block is threaded onto the outer wall of the reciprocating screw, and a tape is provided on the upper left side of the threaded block. The output end of the drive motor is fixedly connected to the drive wheel. This packaging machine with a weighing structure, by incorporating a cutting device, facilitates the removal of the packaged boxes from the weighing scale, thereby improving work efficiency.

[0004] While the aforementioned solution, by incorporating a packaging device that allows tape to be evenly wrapped around the outer wall of the box, improving packaging efficiency and reducing manual labor, lacks a tape-pressing mechanism in actual use. This results in the tape not adhering firmly when sealing the packaging box. To address this, we propose a reciprocating packaging machine with a weighing mechanism. This solves the problem of weak tape adhesion in the previous solution, improves packaging tightness, and effectively enhances the packaging box's resistance to pressure during transport, ensuring product integrity.

[0021] 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.

Therefore, they should not be construed as limitations on this utility model.

[0023] Example: A reciprocating packaging machine with a weighing mechanism, such as Figures 1-4As shown, the system includes a packaging platform 1, a weighing platform 2 fixedly mounted on the top of the packaging platform 1, a weight sensing integrated module installed at the bottom of the weighing platform 2, baffles 21 fixedly mounted at both ends of the weighing platform 2, support columns 5 fixedly mounted at both ends of the packaging platform 1, a fixed arm 6 fixedly mounted on one side of the support column 5, a drive motor 7 fixedly mounted at one end of the fixed arm 6, a cutter 8 fixedly connected to the output end of the drive motor 7, a top plate 9 fixedly mounted on the top of the support column 5, the top plate 9 having a strip-shaped limiting groove 91, a reciprocating mechanism 3 mounted above the weighing platform 2, the reciprocating mechanism 3 including a reciprocating lead screw 31 and a servo motor 32, the output end of the servo motor 32 being fixedly connected to one end of the reciprocating lead screw 31 via a coupling, a packaging mechanism 4 fixedly mounted at the bottom of the reciprocating mechanism 3, the packaging mechanism 4 including a fixed plate 41, and a vertically fixed mounting plate 41 at the bottom. A fixed column 42 is provided, and a first rotating shaft 43 is fixedly installed on the bottom side of the fixed column 42. A nut 47 is detachably threaded to one end of the first rotating shaft 43. A tape roll 44 is movably inserted into the outside of the first rotating shaft 43. The two ends of the reciprocating screw 31 are rotatably installed on the side of the support column 5 near the weighing platform 2 through bearings. The reciprocating screw 31 passes through and is threadedly connected to a movable block 33. A limit slider 34 is fixedly installed at the top of the movable block 33. The limit slider 34 is matched and slidably connected to the strip-shaped limit groove 91. The fixed plate 41 is fixedly installed at the bottom of the movable block 33 by standard screws. The servo motor 32 is fixedly installed on the side of the support column 5 away from the strip-shaped limit groove 91. A guide plate 10 is fixedly installed on one side of the weighing platform 2. A PLC controller 11 is fixedly installed on the top surface of the packaging table 1. The PLC controller 11 is electrically connected to the servo motor 32 and the weighing platform 2.

[0024] In this embodiment, the PLC controller 11 activates the servo motor 32, which drives the reciprocating screw 31 to rotate. This causes the movable block 33 to move along the strip-shaped limiting groove 91 from one end to the other, thereby moving the tape roll 44 from one end of the top surface of the packaging box to the other, achieving an automatic tape sealing effect. After the sealing is completed, the PLC controller 11 starts the drive motor 7, which drives the cutter 8 to rotate one revolution, thus achieving a tape cutting effect. After the packaging box is sealed, the guide plate 10 set on one side of the weighing platform 2 allows the staff to directly push the packaging box onto the storage basket or conveyor belt, saving the inconvenience of manual handling.

[0025] like Figures 1-4As shown, a support arm 45, horizontal to the reciprocating screw 31, is fixedly installed on one side of the upper end of the fixed plate 41. A tape pressing assembly 46 is movably installed at the end of the support arm 45 away from the fixed plate 41. The tape pressing assembly 46 includes a movable pressure rod 461. The top end of the movable pressure rod 461 is hinged to the support arm 45. A return spring 462 is connected between the side of the movable pressure rod 461 near the fixed plate 41 and the bottom side of the support arm 45. A second rotating shaft 463 is vertically installed at the bottom end of the movable pressure rod 461. The horizontal height of the second rotating shaft 463 is not less than one centimeter lower than that of the first rotating shaft 43. A pressing roller 464 is movably sleeved on the outside of the second rotating shaft 463. An elastic rubber layer is pasted on the outside of the pressing roller 464. The first rotating shaft 43 and the second rotating shaft 463 are horizontally arranged relative to each other. The first rotating shaft 43, the second rotating shaft 463, the strip-shaped limiting groove 91, and the reciprocating screw 31 are perpendicular to each other.

[0026] In this embodiment, by installing a tape pressing assembly 46 at one end of the support arm 45 of the packaging mechanism 4, the servo motor 32 can drive the tape roll 44 to roll left and right during the pasting process, and simultaneously drive the pressing roller 464 in the tape pressing assembly 46 to roll synchronously. Furthermore, a return spring 462 is connected between the side of the movable pressure rod 461 near the fixed plate 41 and the bottom side of the support arm 45. The horizontal installation height of the pressing roller 464 is lower than that of the tape roll 44, so that the pressing roller 464 follows the tape roll 44 closely and can play an elastic pressing role on the tape to enhance the tightness between the tape and the surface of the packaging box.

[0027] In this embodiment, a reciprocating packaging machine with a weighing mechanism is used by first connecting the machine's power interface to an external power source. After the packaging box is weighed on the weighing platform 2, the top opening of the packaging box is closed, and one end of the tape roll 44 is manually pulled and pasted to one side of the packaging box. Then, the servo motor 32 is turned on by the PLC controller 11 to drive the reciprocating screw 31 to rotate, thereby driving the movable block 33 to move along the strip-shaped limiting groove 91 from one end to the other. This, in turn, drives the tape roll 44 to move from one end of the top surface of the packaging box to the other end. During the movement of the tape roll 44, the pressing roller 464 presses the tape and rolls synchronously, tightly adhering it to the surface of the packaging box. This ensures that the tape can firmly adhere to the sealing point or the surface of the box, preventing the packaging box from cracking or being damaged at weak points during transportation due to inadequate tape adhesion, thus ensuring production quality. After the sealing is completed, the PLC controller 11 starts the drive motor 7 to drive the cutter 8 to rotate one revolution, thereby achieving the tape cutting effect. Then the movable block 33 is returned to its initial position for the next round of packaging operations. After the packaging box is sealed, the guide plate 10 set on one side of the weighing platform 2 allows the staff to directly push the packaging box onto the storage basket or conveyor belt, saving the inconvenience of manual handling and improving production efficiency.
