Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, and more specifically, to a film-coated weighing packaging equipment. Background Technology

[0002] In the field of packaging equipment technology, film coating is a common method of protection for cylindrical objects (such as tires, rollers, etc.). Traditional film coating equipment typically employs the following two methods:

[0003] Manual operation mode: Workers manually place objects, start equipment and monitor the lamination process, which has the problems of low efficiency and high labor costs;

[0004] Semi-automatic equipment: The object is transported to the packaging station by a conveyor belt, and unidirectional film is applied by a fixed film roll.

[0005] The main drawbacks of the existing technology are as follows:

[0006] Low level of automation:

[0007] Object placement detection relies on manual observation or simple photoelectric sensors, which cannot accurately trigger the packaging process.

[0008] Insufficient coating integrity:

[0009] For cylindrical objects, unidirectional coating can easily lead to incomplete coverage, requiring multiple adjustments to the object's angle.

[0010] Poor adaptability:

[0011] Fixed-height membrane rolls cannot fit objects of different sizes, requiring manual adjustment of the equipment.

[0012] Therefore, there is an urgent need for an intelligent film-coating packaging device that integrates automatic detection, weighing triggering, and dynamic adjustment, and can achieve full surface coating of cylinders. Utility Model Content

[0013] The problem this invention addresses is: how to make film-coated weighing and packaging equipment more automated.

[0014] To solve the above problems, this utility model provides a film-coated weighing and packaging device, comprising:

[0015] Base;

[0016] Two drive rollers are symmetrically arranged on the base, and at least one drive roller is connected to a drive motor.

[0017] A weight sensor installed at the drive roller is used to detect the presence of the packaged item and generate a signal.

[0018] The lifting module has a support platform fixed on its slide.

[0019] A rotary motor fixed to the support platform has its output shaft passing downward through the support platform and connecting to the rotary table;

[0020] The telescopic cylinder installed at the bottom of the rotary table has a winding bracket fixed to the end of its piston rod.

[0021] The winding shaft, fixed to the bottom of the winding bracket, is used to install the film roll;

[0022] When the weight sensor detects the packaged item, it triggers the lifting module to raise the supporting platform. The rotary motor drives the wrapping film roll to rotate and wrap the packaged item. At the same time, the drive motor drives the drive roller to rotate to complete the wrapping.

[0023] Optionally, the two drive rollers are symmetrically arranged in the horizontal direction to support and drive cylindrical packaged items such as tires.

[0024] Optionally, the weight sensor is integrated into the support structure of the drive roller to detect the pressure on the drive roller in real time.

[0025] Optionally, the lifting module is a linear module that moves vertically, and its slide is rigidly connected to the supporting platform.

[0026] Optionally, the piston rod of the telescopic cylinder extends and retracts in the horizontal direction, driving the winding bracket and the coating film roll to make fine adjustments to their width.

[0027] Optionally, the winding support is a U-shaped structure, with the winding shaft fixed at the bottom of its two side walls, and the covering film roll is detachably sleeved on the winding shaft.

[0028] Optionally, the drive motor is fixedly mounted on the base, and its output shaft is coaxially connected to the drive roller via a coupling.

[0029] Compared with the prior art, the film-coated weighing and packaging equipment of this utility model has the following beneficial effects:

[0030] This invention involves placing a tire on two drive rollers, with a weight sensor detecting the pressure signal. The signal triggers a lifting module to raise the supporting platform to a set height. A rotary motor drives a rotating table, causing the coating film to rotate around the tire. Simultaneously, the drive motor rotates the drive rollers, causing the tire to rotate and further ensuring the coating film completely covers the tire surface. The coordinated movement of the rotating film roll and the tire's rotation achieves seamless coating, with multiple modules—weighing, lifting, rotating, and driving—working in tandem to reduce manual intervention.

[0038] like Figures 1 to 2 As shown, this utility model embodiment provides a film-coated weighing and packaging device, including:

[0039] Base 100;

[0040] Two drive rollers 101 are symmetrically arranged on the base 100, and at least one drive roller 101 is connected to a drive motor 110.

[0041] A weight sensor located at the drive roller 101 is used to detect the presence of the packaged item and generate a signal.

[0042] The lifting module 109 has a supporting platform 107 fixed on its slide;

[0043] A rotary motor 108 fixed to the support platform 107 has its output shaft passing downward through the support platform 107 and connected to the rotary table 106.

[0044] The telescopic cylinder 105, which is installed at the bottom of the rotary table 106, has a winding bracket 103 fixed to the end of its piston rod.

[0045] The winding shaft 104, fixed to the bottom of the winding bracket 103, is used to install the wrapping film roll 102. When the weight sensor detects the packaged item, it triggers the lifting module 109 to lift the support platform 107. The rotary motor 108 drives the wrapping film roll 102 to rotate and wrap the packaged item. At the same time, the drive motor 110 drives the drive roller 101 to rotate to complete the wrapping.

[0046] The tire is placed on two drive rollers 101, and a weight sensor detects the pressure signal. The signal triggers the lifting module 109 to raise the support platform 107 to a set height. The rotary motor 108 drives the rotary table 106 to rotate the covering film roll 102 around the tire. At the same time, the drive motor 110 rotates the drive rollers 101, causing the tire to rotate, further ensuring that the covering film completely covers the tire surface. The coordinated movement of the rotating film roll and the tire's rotation achieves seamless covering, and the multi-module linkage of weighing, lifting, rotation, and drive reduces manual intervention.

[0047] Two drive rollers 101 are symmetrically arranged in the horizontal direction to support and drive cylindrical packaged items such as tires. The two drive rollers 101 are symmetrically mounted on the base 100, and the tire is placed across the two rollers, driven by a single-sided drive motor 110.

[0048] A weight sensor is integrated into the support structure of the drive roller 101 to detect the pressure on the drive roller 101 in real time. The weight sensor is embedded inside the bearing housing of the drive roller 101 to monitor the pressure on the roller body in real time. When the pressure value exceeds the threshold, it is determined that an object is present.

[0049] The lifting module 109 is a linear module that moves vertically, and its slide is rigidly connected to the support platform 107.

[0050] The lifting module 109 uses a lead screw slide, with the support platform 107 fixed to the slide base. The motor drives the slide to move up and down along the Z-axis, precisely controlling the initial height of the film roll. This adapts to the initial film coating height of tires of different sizes.

[0051] The piston rod of the telescopic cylinder 105 extends and retracts horizontally, causing the winding bracket 103 and the film roll 102 to make slight width adjustments. When the piston rod of the telescopic cylinder 105 extends horizontally, it pushes the winding bracket 103 and the film roll 102 to move laterally, thus finely adjusting the distance between the film roll and the tire.

[0052] The winding support 103 has a U-shaped structure, with winding shafts 104 fixed to the bottom of its two side walls. The film roll 102 is detachably fitted onto the winding shafts 104. The winding shafts 104 are installed in the shaft holes at the bottom of the two side walls of the U-shaped winding support 103. The film roll 102 is inserted into the shaft and secured by quick-release clips. This simplifies the film roll replacement process and improves efficiency.

[0053] The drive motor 110 is fixedly mounted on the base 100, and its output shaft is coaxially connected to the drive roller 101 via a coupling. The drive motor 110 is fixed on the base 100, and its output shaft is vertically connected to the shaft of the drive roller 101 via a coupling, directly transmitting torque.

[0054] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
