Description

Technical Field

[0001] The utility model relates to the technical field of transmission mechanisms, in particular to a film rolling servo transmission mechanism for a packaging machine. Background Art

[0002] A packaging machine is a device used to package products into final sales units. Servo transmission mechanisms play a vital role in packaging machines. Servo transmission mechanisms can provide high-precision position, speed and force control. Through the servo transmission mechanism, packaging machines can easily adjust parameters to adapt to packages of different sizes and shapes, and realize changes in production lines in a short time.

[0003] The transmission belt in the servo transmission mechanism has the problem of looseness during use. The loose transmission belt may cause unstable movement of the equipment, generate vibration or shaking, increase equipment wear, shorten the service life of the equipment, affect the accuracy of product processing, and require shutdown adjustment. For this reason, we propose a packaging machine film roll servo transmission mechanism to solve the existing problem. Utility Model Content

[0009] Preferably, a collection box is provided at the upper end of the bottom plate, a fan is provided inside the collection box, and a suction pipe is provided at one end of the collection box and is installed inside the sleeve box.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1-Figure 4 As shown, a film rolling servo transmission mechanism of a packaging machine proposed by the utility model includes a sleeve box 3, a driving wheel 5, a hydraulic rod 7, a motor 10, a motor 2 13, a bottom plate 12 and a tensioning sleeve 18, bearing brackets 16 are arranged on both sides of the upper end of the bottom plate 12, a driving wheel 5 and a driven wheel 15 are rotatably mounted inside the bearing bracket 16, and a belt 2 is rotatably sleeved on the outer walls of the driving wheel 5 and the driven wheel 15, a winding roller 1 is arranged at one end of the driven wheel 15, a docking seat 17 is arranged at one end of the driving wheel 5, and a docking shaft 19 is arranged above the bottom plate 12;

[0021] A slide seat 9 is disposed at the lower end of the motor 10, and a symmetrically distributed guide rail 6 is disposed at the upper end of the bottom plate 12, and the slide seat 9 is slidably mounted on the outer wall of the guide rail 6;

[0022] The upper end of the bottom plate 12 is provided with symmetrically distributed clamping blocks 8, and the clamping blocks 8 are rotatably mounted with the telescopic end of the hydraulic rod 7;

[0023] Limiting rings 14 are provided at both the front and rear ends of the driving wheel 5 and the driven wheel 15;

[0024] Based on the implementation steps of Example 1: the motor 10 is slidably installed on the guide rail 6 through the slide 9, and the block 8 rotates at this time to allow the slide 9 to pass. After the docking shaft 19 docks with the docking sleeve, the block 8 rotates to correspond to the slide 9, and the hydraulic rod 7 drives the block 8 to move. When it fits with the slide 9, the slide 9 is pulled to make the motor 10 stable on the slide 9. The motor 10 drives the driving wheel 5 to rotate, and through the linkage of the belt 2, the driven wheel 15 is driven to rotate, and then the winding roller 1 is driven to rotate;

[0025] Motor 10 is a servo motor. When in use, due to the fast response speed of the servo transmission mechanism, the movement of the packaging machine can be adjusted quickly, and high-precision position, speed and force control can be provided. The parameters can be easily adjusted to adapt to packages of different sizes and shapes, and changes in the production line can be achieved in a short time.

[0026] like Figure 1-Figure 4 As shown, compared with the first embodiment, the utility model proposes a packaging machine film roll servo transmission mechanism, and this embodiment also includes: a sleeve box 3 is sleeved on the outer side of the belt 2, and brushes 20 are arranged on the inner walls of the upper and lower ends of the sleeve box 3 at equal distances, a tensioning sleeve 18 is sleeved on the outer side of the belt 2, and symmetrically distributed wheels 22 are rotatably installed between the tensioning sleeves 18, a motor 2 13 is arranged on the upper end of the bottom plate 12, a screw 26 is arranged on the upper end of the motor 2 13, and a nut 21 sleeved on the outer wall of the screw 26 is arranged at one end of the tensioning sleeve 18.

[0027] A collecting box 4 is disposed at the upper end of the bottom plate 12 , a fan 23 is disposed inside the collecting box 4 , and a suction pipe 11 penetrating and installed inside the sleeve box 3 is disposed at one end of the collecting box 4 .

[0028] A sliding sleeve 25 is disposed at one end of the tensioning sleeve 18 , and a guide rod 24 whose lower end is connected to the bottom plate 12 is slidably inserted into the sliding sleeve 25 .

[0029] The docking seat 17 and the docking shaft 19 are interlocked with each other. The suction end of the fan 23 is located inside the collection box 4. The suction end corresponds to the suction pipe 11, and a filter is provided at the suction end.

[0030] In this embodiment, when the belt 2 is loose, the motor 2 13 operates to drive the screw 26 to rotate. Since the tensioning sleeve 18 slides on the outer wall of the fixed guide rod 24 through the sliding sleeve 25, a longitudinal sliding guide is obtained. The screw 26 applies a longitudinal force to the thread, and the thread moves longitudinally on the outer wall of the screw 26, driving the tensioning sleeve 18 to move synchronously. The belt 2 is pulled by the rotating wheel 22. During the pulling process, the belt 2 is in contact with the rotation of the belt 2 to reduce wear. The belt 2 is tensioned, avoiding the problem of relatively long shutdown operations, stopping the production line, and affecting processing. The belt 2 is tensioned without stopping the machine, so that the packaging machine can produce stably without affecting the production volume.

[0031] When the belt 2 rotates, it comes into contact with the brush 20, and the dust and foreign matter adhered to the outer wall are brushed off, avoiding the problem of increased friction loss when the foreign matter and dust come into contact with the driving wheel 5 and the driven wheel 15 of the servo transmission structure. The fan 23 is in operation, and the suction force acts on the sleeve box 3 through the suction pipe 11. The peeled foreign matter is sucked into the collection box 4, avoiding the problem of pollution to the packaging production caused by the peeled foreign matter, and improving the service life of the belt 2.

[0032] The above-mentioned specific embodiments are only several preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.

[0033] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
