Technical Field

[0001] This application relates to the field of load-bearing capacity testing technology, and more specifically, to a load-bearing capacity testing device for an automatic quantitative pillow packaging machine. Background Technology

[0002] Pillow packaging machines are continuous packaging machines with very strong packaging capabilities, suitable for various specifications of food and non-food packaging. They can be used not only for packaging unlabeled packaging materials, but also for high-speed packaging of roll materials with pre-printed trademark patterns. Currently, before an automatic quantitative pillow packaging machine is put into use, it is necessary to perform weighing and testing.

[0003] A search revealed a public announcement (CN221938527U) that discloses a load-bearing detection device for an automatic quantitative packaging machine, comprising an electric push rod, a base, and a support plate. The support plate is fixedly connected to one side of the top of the base, and a threaded rod is movably installed on the top of the base on one side of the support plate. This application can realize automatic detection and automatic stop detection functions, thereby preventing damage to the load-bearing structure of the packaging machine.

[0004] However, the application requires manual screwing of the threaded rod during the vertical adjustment of the limiting plate, which is time-consuming and labor-intensive, and also results in low efficiency in adjusting the vertical position of the limiting plate.

[0005] To address the aforementioned issues, this application provides a load-bearing detection device for an automatic quantitative pillow packaging machine. Utility Model Content

A connecting groove 9 is provided between the second gear 8 and the first gear 7. A through groove 9 is horizontally opened in the inner cavity of the support plate 2, and a transmission chain 10 is installed through the inner side of the through groove 9. The transmission chain 10 is engaged with the connection point of the outer ends of the first gear 7 and the second gear 8. The center of the bottom of the second gear 8 is connected to the motor 11 through a rotating shaft, and the bottom of the motor 11 is fixedly installed on the outer wall of the support plate 2 through a pad. The outer sides of the second gear 8 and the motor 11 are jointly fitted with an outer cover 12. Limiting rods 13 are provided on both sides of the threaded rod 4. The two limiting rods 13 are slidably sleeved on both sides of the limiting plate 3, and the two limiting rods 13 are fixedly installed on the top of the base 1. A load-bearing detection component is provided on one side of the top of the support plate 2.

[0033] A non-slip pad is fixedly installed on the bottom side of the limiting plate 3 facing away from the support plate 2. The non-slip pad is made of silicone rubber. A metal bearing is sleeved on the outer wall of the bottom end of the threaded rod 4. The metal bearing is embedded in the top position of one side of the base 1. The outer cover 12 has a "U"-shaped frame structure. The outer cover 12 contacts one end face of the support plate 2. Multiple louvers 121 are linearly and uniformly fixedly installed on the inner wall of the side of the outer cover 12 facing away from the support plate 2. Ear blocks 122 are fixedly connected to the four outer walls of the end of the outer cover 12 near the support plate 2. Each ear block 122 has a cavity provided with The screw 123 and each lug 122 are fixedly screwed onto the outer surface of the support plate 2. The outer cover 12 can protect the motor 11 and the second gear 8, and can also facilitate the heat dissipation of the motor 11 by utilizing the multiple louvers 121 on one side. With the arrangement of each lug 122 and screw 123 on the outer cover 12, it is easy to assemble and fix the outer cover 12 on one side of the support plate 2, and it can also be removed when needed to carry out inspection or maintenance operations on the motor 11, the second gear 8, and the transmission chain 10.

[0034] Please see Figure 1 and Figure 2The load-bearing detection component includes a fixed plate 14 fixedly connected to one side wall of the top of the support plate 2. A detection cylinder 15 is fixedly installed through the side of the fixed plate 14 away from the support plate 2. A fixed ring 16 is fixedly connected to the drive end of the bottom of the detection cylinder 15, and a pressure sensor 17 is fixedly connected to the bottom of the fixed ring 16. An alarm 18 is fixedly installed on one side of the front end face of the fixed plate 14.

[0035] Positioning components 19 are fixedly connected to the front and rear side walls of the upper end of the base 1. Each positioning component 19 has bolt holes through it on both sides. A control panel 20 is fixedly installed on one outer wall of the upper end of the support plate 2. The control panel 20 is located above the outer cover 12. The outer surface of the control panel 20 is equipped with a display screen and buttons. The control panel 20 can be electrically connected and controlled to the motor 11, the detection cylinder 15, the pressure sensor 17, and the alarm 18 through wires.

[0036] The implementation principle of this embodiment is as follows: When in use, the whole assembly is in a complete assembly state. The positioning parts 19 and bolt holes on both sides of the base 1 can be used to realize the positioning and assembly work of the whole assembly on the side of the required detection position on the automatic quantitative pillow packaging machine to be tested. At the same time, the vertical position of the limit plate 3 is adjusted downward so that it presses against the plane to be tested on the packaging machine, thereby improving the stability of the overall load-bearing detection component for the load-bearing detection work of the packaging machine. The load-bearing detection component includes: a fixed plate 14, a detection cylinder 15, a fixed ring 16, a pressure sensor 17, and an alarm 18. The load-bearing detection component is a prior art with the same structure and principle as the prior art published in the prior art document (announcement) number: CN221938527U. The specific load-bearing detection process of the packaging machine can be referred to the contents of the prior art document, which will not be elaborated here.

[0037] During the adjustment of the vertical position of the limiting plate 3, it is only necessary to control the start motor 11 to make the second gear 8 rotate. Due to the meshing and rotation of the transmission chain 10 on the second gear 8 and the first gear 7 (the diameter of the first gear 7 is larger than the diameter of the second gear 8, and the transmission cooperation between the two and the transmission chain 10 can be referred to as the motion principle of an ordinary bicycle), the first gear 7 rotates, which drives the I-shaped shaft 5 and the threaded rod 4 to rotate. Together with the limiting rods 13 on both sides to limit the vertical movement of the limiting plate 3, the vertical position of the limiting plate 3 can be automatically adjusted, effectively avoiding the drawbacks of manual operation.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
