Description

Technical Field

[0001] This utility model relates to the field of desiccant packing machine technology, and in particular to an automatic single-packing machine for desiccant packaging. Background Technology

[0002] Currently, when producing individual packets of desiccant preservatives, each box contains a specified quantity according to customer orders. Each packet produced by the packaging machine falls onto a conveyor belt, where it drops into a pre-placed plastic basket. Once the basket is full, the worker removes it and replaces it with an empty one to continue collecting preservatives. The remaining packets are then manually counted and placed into designated cardboard boxes. Currently, the entire process is manual, which is cumbersome. Furthermore, one operator managing 2-4 machines simultaneously can be inefficient, significantly reducing production efficiency and compromising product quality. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a single-pack automatic desiccant packaging machine.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an automatic single-packing box machine for desiccant packaging, comprising a mobile platform base frame, a mobile platform provided above the mobile platform base frame, a motor drive switching device provided between the bottom of the mobile platform and the top of the mobile platform base frame, the motor drive switching device comprising a precision lead screw mechanism, the precision lead screw mechanism being movably mounted on the top of the mobile platform base frame, one end of the lead screw mechanism being connected to a stepper motor, the moving end of the precision lead screw mechanism being connected to the bottom of the mobile platform, and a cylinder switching device provided above the mobile platform.

[0005] Preferably, both ends of the lead screw of the precision lead screw mechanism are equipped with bearing seats, and the bearing seats are installed on the top of the mobile platform base frame.

[0006] Preferably, a synchronous pulley is installed at one end of the lead screw of the precision lead screw mechanism and at the movable end of the stepper motor, and a synchronous belt is connected between the two synchronous pulleys.

[0007] Preferably, the surface of the mobile platform base frame has a motor mounting hole, the stepper motor is located in the motor mounting hole, and a motor fixing bracket is connected between the housing of the stepper motor and the surface of the mobile platform base frame.

[0008] Preferably, the precision lead screw mechanism has parallel pads on both sides, a linear guide rail is mounted on the top of the pads, a linear bearing is movably connected to the top of the linear guide rail, and the outside of the linear bearing is connected to the bottom of the moving platform.

[0009] Preferably, the cylinder switching device includes a cylinder mounting base, the bottom end of which is installed on the bottom of the moving platform. The cylinder mounting base is bent, and the top end of which extends to the top of the moving platform. A rodless cylinder is connected to the top end of the cylinder mounting base. A steering slide is connected to the movable end of the rodless cylinder. A sensing groove is provided at the bottom end of the steering slide. Photoelectric sensors are installed on the surfaces of two corresponding positions in the steering slide. The sensing ends of the photoelectric sensors extend into the sensing groove.

[0010] Preferably, a square tube is installed on the top of the mobile platform base frame, and a control box is installed on the top of the square tube.

[0011] Preferably, omnidirectional wheels are installed at all four corners of the bottom of the mobile platform base frame.

[0012] Preferably, the top of the mobile platform is equipped with a plurality of weighing sensors arranged in a matrix.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This solution utilizes a cylinder switching device. As the preservative passes through the output end of the steering slide, a photoelectric sensor counts the presence or absence of preservative. When the quantity in one direction reaches a preset value, a signal is sent to a two-position solenoid valve to control the slider on the rodless cylinder to slide horizontally, thereby moving the steering slide to switch the direction in which the preservative falls. After a row of cartons is filled with preservative, the motor-driven switching device moves the moving platform horizontally, moving the empty cartons below the steering slide. This ensures that the preservative is evenly distributed across multiple cartons. Compared to manual loading, this simplifies the loading process, saves manpower, and improves the loading efficiency of the preservative. Attached Figure Description

[0020] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0021] like Figure 1-4 The diagram shows an automatic single-packet carton packing machine for desiccants, comprising a mobile platform base 3, a mobile platform 5 mounted above the base 3, and a motor drive switching device 4 located between the bottom of the mobile platform 5 and the top of the base 3. The motor drive switching device 4 includes a precision lead screw mechanism 48, which is movably mounted on the top of the base 3. One end of the lead screw of the precision lead screw mechanism 48 is connected to a stepper motor 44, and the moving end of the precision lead screw mechanism 48 is connected to the bottom of the mobile platform 5. When two cartons in a row reach... When the preset range is reached, the movable end of the stepper motor 44 is rotated, which in turn rotates the lead screw of the precision lead screw mechanism 48. This causes the movable end of the precision lead screw mechanism 48 to move horizontally. The movable end then drives the moving platform 5 to move to the left in sync. When the moving platform 5 reaches the preset distance of the control box 6, the two cartons in the second row are moved to the bottom of the turning slide 73. Then, the rodless cylinder 72 is operated to move the turning slide 73 to align with one of the empty cartons. The two empty cartons are then packed in sequence, improving the packing efficiency of the preservative.

[0022] A cylinder switching device 7 is provided above the mobile platform 5. The cylinder switching device 7 includes a cylinder fixing seat 71. The bottom end of the cylinder fixing seat 71 is installed at the bottom of the mobile platform 5. The cylinder fixing seat 71 is bent. The top end of the cylinder fixing seat 71 extends to the top of the mobile platform 5. A rodless cylinder 72 is connected to the top end of the cylinder fixing seat 71. A steering slide 73 is connected to the movable end of the rodless cylinder 72. A sensing groove is opened at the bottom end of the steering slide 73. Photoelectric sensors 74 are installed on the surfaces of two corresponding positions in the steering slide 73. The sensing end of the photoelectric sensor 74 extends into the sensing groove. The photoelectric sensor 74 counts by sensing the presence or absence of preservative. The preservative falls onto the inclined surface of the steering slide 73 via the conveyor belt. The preservative moves along the inclined direction of the steering slide 73 and falls into the carton. When the quantity in one direction reaches a preset value, the slider on the rodless cylinder 72 is controlled to slide left and right by sending a signal to the two-position solenoid valve, thereby moving the steering slide 73 to switch the direction in which the preservative falls.

[0023] The precision lead screw mechanism 48 has bearing housings with bearings installed at both ends of the lead screw. The bearing housings with bearings are installed on the top of the mobile platform base frame 3. When the lead screw of the precision lead screw mechanism 48 is subjected to force, it rotates in the bearing housing through the bearings.

[0024] Both the lead screw of the precision lead screw mechanism 48 and the movable end of the stepper motor 44 are equipped with synchronous pulleys 47. A synchronous belt 46 is connected between the two synchronous pulleys 47. The movable end of the stepper motor 44 drives the lead screw of the precision lead screw mechanism 48 to rotate through the two synchronous pulleys 47 and the synchronous belt 46, which plays the role of transmitting torque.

[0025] The surface of the mobile platform base frame 3 has a motor mounting hole, and the stepper motor 44 is located in the motor mounting hole. A motor fixing bracket 45 is connected between the housing of the stepper motor 44 and the surface of the mobile platform base frame 3, and the motor fixing bracket 45 fixes the position of the stepper motor 44.

[0026] The precision lead screw mechanism 48 has parallel pads 43 on both sides. A linear guide rail 42 is installed on the top of the pads 43. A linear bearing 41 is movably connected to the top of the linear guide rail 42. The outside of the linear bearing 41 is connected to the bottom of the moving platform 5. The pads 43 provide sliding support for the moving platform 5. The linear bearing 41 slides on the linear guide rail 42 as the moving platform 5 moves, which improves the stability of the moving platform 5 when it moves under load.

[0027] A square tube 2 is installed on the top of the mobile platform base frame 3, and a control box 6 is installed on the top of the square tube 2. The control box 6 contains a controller, which is a PLC controller. The square tube 2 is used to fix the control box 6 at a high position, making it convenient for staff to operate the PLC controller.

[0028] The mobile platform base frame 3 is equipped with casters 1 at the four corners of the bottom, which allows the equipment to be moved.

[0029] Multiple weighing sensors 8 arranged in a matrix are installed on the top of the mobile platform 5. The weighing sensors 8 are used to measure whether the weight of each box of products meets the requirements.

[0030] Operating Procedure: Assuming the customer requires 1,000 packets of preservative per carton, during the preservative packaging machine preparation, firstly, the automatic carton packer is powered on via control box 6, and then the moving platform is zeroed via control box 6. Parameter settings are then configured on control box 6. First, the quantity parameter is preset to 1,000 packets, corresponding to the function of photoelectric sensor 74. Next, the weight is preset, setting the maximum and minimum tolerance ranges for the weight of 1,000 packets of preservative, corresponding to the function of weighing sensor 8. Finally, the moving distance of the moving platform is set via control box 6 according to the length of the carton, ensuring that the preservative falls correctly into the carton when the moving platform 5 switches cartons. The preparation work is now complete.

[0031] During normal operation of the automatic carton packing machine, the photoelectric sensor 74 counts the cartons at the first station. After the cartons at the first station reach the preset value, the weighing sensor 8 weighs the cartons at the first station. When the cartons at the first station reach the preset range, the dual-position solenoid valve controls the cylinder to move, aligning the steering slide 73 with the cartons at the second station for counting. When the second station reaches the preset value, the stepper motor 44 rotates, driving the moving platform 5 to move the control box 6 to the left a preset distance. The rodless cylinder 72 moves to align with the third station, and then counts the cartons at the third station. When the third station reaches the preset value, the rodless cylinder 72 moves to count and pack the cartons at the fourth station. When some cartons are loaded and the machine switches to the next control box to load preservatives, the operator can choose to remove the loaded cartons and replace them with empty cartons. When all four cartons are loaded, the machine can start counting and loading preservatives again from the first replaced control box. This process facilitates continuous operation of the automatic carton packing machine.
