Description

Technical Field

[0001] The utility model relates to the technical field of packaging, in particular to a long-side carton sealer. Background Art

[0002] In the packaging industry, as a key device on the automated production line, the performance of the carton sealer directly affects the packaging efficiency and quality. In recent years, although various carton sealing technologies have been proposed and applied, there are still significant technical bottlenecks in the traditional equipment for long-side carton sealing scenarios.

[0003] For example, the Chinese patent with the publication number CN106218978B discloses a four-corner carton sealer. The device includes a frame body, an inlet box auxiliary mechanism, a conveying mechanism, a tape sticking mechanism, and a flattening mechanism. When the carton passes through the flattening mechanism, the conveyor belt needs to pause, and the air cylinder drives the rotary brush of the rotary brush angle mechanism to rotate horizontally to flatten the tape in the vertical direction. The air cylinder drives the long brush of the upper and lower flattening mechanisms to move vertically to flatten the tape in the horizontal direction, completing the carton sealing action. The flattening of the tape by this device belongs to static operation and cannot achieve dynamic adaptation.

[0004] Therefore, we have designed a long-side carton sealer. Summary of the Utility Model

[0005] In order to overcome the deficiencies in the background art, the utility model discloses a long-side carton sealer.

[0006] To achieve the above object, the utility model adopts the following technical solutions:

The pressing rod is driven by the air cylinder to lift and lower along the guiding shaft to press the box body;

[0013] The case sealer core is fixed on the outside of the pressing mechanism and is used for sealing the tape on the long side of the box body.

[0014] The rolling brush is arranged at the discharging end of the pressing rod. The rolling brush includes a shaft body and end plates located at the ends of the shaft body.

[0015] Further, a linear bearing is arranged on the surface of the guiding shaft, and the pressing rod is slidably connected with the guiding shaft through the linear bearing to ensure the stability of the pressing action.

[0016] Further, a photoelectric sensor is integrated at the feeding end of the pressing rod, and its signal output end is electrically connected with the control system of the lateral adjustment mechanism, which is used for detecting the feeding state of the box body and triggering the operation of the lateral adjustment mechanism.

[0020] Further, both ends of the ball screw are fixed to the main body frame through flange bearings and are connected with the output shaft of the servo motor through a coupling.

[0021] Further, the rolling brush is drivenly connected with the output shaft of the driving motor of the pressing rod conveyor belt.

[0022] Further, the main body frame is provided with a lateral slide rail, and the moving platform and the pressing rod are slidably connected with the corresponding lateral slide rails. Among them, the lateral slide rail corresponding to the pressing rod is fixedly connected with the output end of the cylinder.

[0023] Further, the support rod conveyor belt and the pressing rod conveyor belt on the same side are located in the same vertical plane.

[0024] Compared with the prior art, the beneficial effects of the utility model are:

[0025] 1.

[0036] The present utility model can be explained in detail through the following embodiments. The purpose of disclosing the present utility model is to protect all technical improvements within the scope of the present utility model. In the description of the present utility model, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right", etc. indicating the orientation or position relationship, it is only corresponding to the drawings of the present application for the convenience of describing the present utility model; it should be understood that if there are terms such as "end", "side", "end part", "side part", "lateral", "longitudinal", etc. indicating the orientation or position relationship, it is only corresponding to the length and width of the corresponding component, that is, the "end part" indicates the head and tail regions in the length direction of the corresponding component, and the "side part" indicates the head and tail regions in the width direction of the corresponding component; it is for the convenience of describing the present utility model rather than indicating or implying that the device or element referred to must have a specific orientation.

[0037] Embodiment 1, in combination with the attached Figures 1-6 , a long-side carton sealer, comprising:

[0038] A main body frame 1, with two moving platforms 2 symmetrically arranged inside;

[0039] A horizontal adjustment mechanism 3, horizontally arranged on the main body frame 1, including a servo motor 31 and a ball screw 32, for driving the two moving platforms 2 to move in the opposite direction along the width direction of the main body frame 1 to adjust the carton sealing width;

[0040] According to needs, to improve the stability of the movement of the moving platform 2, a horizontal slide rail 11 is provided at the bottom of the main body frame 1, and the moving platform 2 is slidably connected to the horizontal slide rail 11.

[0041] It should be noted that: the ball screw 32 is composed of two sections, and the spiral grooves of the two sections of the ball screw 32 have opposite directions.

[0042] Furthermore, both ends of the ball screw 32 are fixed to the main body frame 1 through flange bearings and are connected to the output shaft of the servo motor 31 through a coupling.

[0043] A longitudinal transmission assembly 4, longitudinally arranged on the upper plate surface of the moving platform 2, including a support rod 41 and a support rod conveyor belt 42, and a feeding guide device 5 is provided at the feeding end of the support rod 41; for supporting and transporting the box body.

[0044] Furthermore, the feeding section of the feeding guide device 5 has a tapered arc structure, and the feeding guide device 5 is located at a position slightly above the outside of the feeding end of the longitudinal transmission assembly 4, for guiding the box body to accurately enter the conveyor belt. That is to say, the two feeding guide devices 5 form an eight-shaped feeding guide structure.

[0045] A guide shaft 6, vertically arranged on the upper plate surface of the moving platform 2 and located outside the longitudinal transmission assembly 4;

[0046] As needed, two guiding shafts 6 are installed on each mobile platform 2, and the tops of the two guiding shafts 6 are connected by a rod to improve stability.

[0047] The pressing mechanism 7 is slidably connected to the guiding shaft 6 and includes a pressing rod 71, a cylinder 72, and a pressing rod conveyor belt 73 provided at the bottom of the pressing rod 71. The pressing rod 71 is driven by the cylinder 72 to move up and down along the guiding shaft 6 to press the box body; specifically, the fixed part of the cylinder 72 is fixedly installed on the main body frame 1.

[0048] Specifically, the pressing rod 71 is slidably connected to the guiding shaft 6 through a mounting plate; for example, a linear bearing 61 is provided on the outer side of the mounting plate, and the inner side is correspondingly connected to the pressing rod 71. The pressing rod 71 is slidably connected to the guiding shaft 6 through the linear bearing 61 to ensure the stability of the pressing action.

[0049] As needed, to improve the stability of the movement of the pressing mechanism 7, a transverse slide rail 11 is provided on the top of the main body frame 1, and the pressing rod 71 is slidably connected to the transverse slide rail 11; specifically, the transverse slide rail 11 is fixedly installed on the mounting plate and is not directly in contact with the main body frame 1. That is, when the telescopic end of the cylinder 72 expands and contracts, it can drive the mounting plate to move up and down, and then drive the transverse slide rail 11 and the pressing rod 71 to move up and down.

[0050] As needed, the material of the conveyor belt is anti-slip rubber, and raised stripes are provided on the surface to enhance the friction with the box body.

[0051] Furthermore, to prevent the box body from being squeezed and deformed, the support rod conveyor belt 42 and the pressing rod conveyor belt 73 on the same side are located in the same vertical plane. Furthermore, the lateral distance between the feeding guiding device 5 and the support rod conveyor belt 42 and the pressing rod conveyor belt 73 on the same side is 100 - 120 mm. That is, the position where the support rod conveyor belt 42 and the pressing rod conveyor belt 73 clamp the box body up and down is 50 - 70 mm away from the position where the tape is bonded, which does not affect the bonding of the tape and is relatively close to the box sealing position.

[0052] The box sealing machine core 8 is fixed on the outside of the pressing mechanism 7 and is used for sealing the long side of the box body with tape; specifically, the box sealing machine core 8 adopts the prior art and will not be described in detail here. For example, the box sealing mechanism disclosed in the prior art CN119240096A.

[0053] The rolling brush 9 is provided at the discharging end of the pressing rod 71. The rolling brush 9 includes a shaft body 91 and an end plate 92 located at the end of the shaft body 91. Both the inner plate surfaces of the shaft body 91 and the end plate 92 have bristles 93, which are used to flexibly press the tape to both side surfaces of the box body edge. That is, the bristles 93 on the shaft body 91 flexibly press one side of the tape, so that this side of the tape fits on the top surface of the upper box cover, and the bristles 93 on the end plate 92 flexibly press the other side of the tape, so that this side of the tape fits on the side wall surface of the lower box body.

[0054] As required, to reduce the power source, the driving motor output shaft of the rolling brush 9 is drivingly connected to the pressing rod conveyor belt 73. That is, the rolling brush 9 does not require an additional power source for driving, which not only reduces the manufacturing cost but also makes the overall structure more compact.

[0055] In a possible implementation, to achieve automatic long-side box sealing operation, a photoelectric sensor 10 is integrated at the feeding end of the pressing rod 71, and its signal output end is electrically connected to the control system of the lateral adjustment mechanism 3, for detecting the box feeding state and triggering the operation of the lateral adjustment mechanism 3.

[0056] The feeding diversion device 5 is integrated with a first mechanical trigger switch 51, and its signal output end is electrically connected to the control systems of the lateral adjustment mechanism 3 and the pressing mechanism 7, for detecting the box feeding state and triggering the stop operation of the lateral adjustment mechanism 3 and the operation of the pressing mechanism 7.

[0057] The feeding end of the pressing rod 71 is integrated with a second detection switch, and its signal output end is electrically connected to the control systems of the pressing mechanism 7 and the conveyor belt, for detecting the box feeding state and triggering the stop operation of the pressing mechanism 7 and the operation of the conveyor belt.

[0058] During installation, conveyor devices are provided on both the feeding side and the discharging side of the long-side box sealer. During use, the conveyor device on the feeding side transports the box to be long-side box sealed to the feeding end. After the photoelectric sensor 10 detects the box, the lateral adjustment mechanism 3 operates. At this time, the two moving platforms 2 move relative to each other until the first mechanical trigger switch 51 is triggered and then stop operating. The pressing mechanism 7 starts to operate until the second detection switch is triggered and stops operating. The support rod conveyor belt 42 and the pressing rod conveyor belt 73 operate synchronously to drive the box to move. During this process, the box sealing machine core 8 performs the operation of sealing the long side of the box with adhesive tape. Subsequently, before the box is about to be transported to the conveyor device on the discharging side, the rolling brush 9 softly presses the adhesive tape onto the box surface to complete the long-side box sealing operation.

[0059] The specific process of the operation of the lateral adjustment mechanism 3 is as follows: The servo motor 31 drives the ball screw 32 to rotate, and the nuts on the moving platforms 2 move, realizing the function of the two moving platforms 2 moving in opposite directions along the width direction of the main frame 1 until the first mechanical trigger switch 51 is triggered. At this time, the distance between the two feeding diversion devices 5 is adapted to the width of the box.

[0060] The specific process of the operation of the pressing mechanism 7 is as follows: The air cylinder 72 drives the pressing rod 71, the pressing rod conveyor belt 73, the second detection switch, and the corresponding lateral slide rail 11 to descend through the mounting plate until the second detection switch is triggered. At this time, the pressing rod conveyor belt 73 presses the upper box cover, making the upper box cover fit tightly.

[0061] The specific way that the rolling brush 9 presses the tape is as follows: the bristles 93 located on the shaft body 91 flexibly press one side of the tape, so that this side of the tape fits against the top surface of the upper box cover, and the bristles 93 located on the end plate 92 flexibly press the other side of the tape, so that this side of the tape fits against the side wall surface of the lower box body; during the specific operation, the feeding side of the rolling brush 9 moves from top to bottom, and the discharging side moves from bottom to top. As shown in the attached Figure 6 figure, the left side is the feeding side and the right side is the discharging side.

[0062] It should be noted that: the box body to be sealed at the long side is assembled by the lower box body and the upper box cover, and there are two long sides that need to be taped.

[0063] The parts not detailed in the present utility model are prior art. For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model; therefore, from any point of view, the above embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description.
