Description

Technical Field

[0001] The utility model relates to a bag clamp, in particular to a swing cylinder bag-supporting type bag clamp. Background Art

[0002] With the continuous innovation of science and technology, industrial production is becoming increasingly high-end, efficient, and refined. This requires industrial products to have intelligent and efficient product features, and the packaging of granular materials is also tending to be automated. Currently, a variety of automated packaging equipment has appeared on the market. Automated packaging equipment has replaced traditional manual packaging. It is widely used due to its fast speed and neat and beautiful packaging.

[0003] The bag clamp is an important component of packaging equipment. During the automatic bagging process of powder and granular materials, the bag clamp clamps the bag to complete the unloading. The bag support rods on both sides of the bag clamp open to flatten the bag opening, and then the bag filled with material is sent to the next process, thus completing the automatic unloading.

[0004] The cylinder body of the lifting cylinder in the existing bag clamp is fixed relative to the bag clamp body during operation. The bag supporting rod frame is arranged at the lower end of the cylinder rod of the lifting cylinder, and the bag supporting rod is arranged on the bag supporting rod frame through the bag supporting cylinder. In this way, during the bag supporting process, the cylinder rod of the lifting cylinder rises and falls to drive the bag supporting rod frame to move up and down, and the bag supporting cylinder drives the bag supporting rod to swing left and right.

[0005] However, in a bag clamp having a fixed lifting cylinder relative to the bag clamp body, the lifting cylinder needs to drive the entire bag clamp frame when driving the bag clamp rod up and down, resulting in a heavy load on the lifting cylinder, which is prone to failure and reduces reliability. Utility Model Content

[0006] The purpose of this utility model is to solve the technical problem that the lifting cylinder in the existing bag clamp needs to drive the entire bag supporting rod frame when driving the bag supporting rod up and down, which causes the load weight of the lifting cylinder to be large, prone to failure, and leads to reduced reliability, and to provide a swing cylinder bag supporting type bag clamp.

[0007] In order to achieve the above purpose, the technical solution adopted by the present utility model is:

[0008] A swing cylinder bag-supporting type bag clamp comprises a main frame, a front guard plate, a rear guard plate and a bag clamping assembly;

[0009] The front guard plate and the rear guard plate are installed on two side surfaces of the main frame in the width direction, and a gap is set between them along the width direction of the main frame; the bag clamping assembly is installed in the gap between the front guard plate and the rear guard plate;

[0010] Its special features are:

[0013] The bag support rod 1 and the bag support rod 2 are arranged on both sides of the front guard plate and the rear guard plate along the length direction of the main frame, and are respectively installed at the output ends of the lifting component 1 and the lifting component 2;

[0014] The bag-supporting component 1 and the bag-supporting component 2 are respectively arranged on the side of the front guard plate and the rear guard plate away from each other, and their installation ends are correspondingly hinged on the outer walls of the front guard plate and the rear guard plate; the bag-supporting component 1 and the bag-supporting component 2 are both provided with two output ends, and the two output ends of the bag-supporting component 1 and the bag-supporting component 2 are respectively hinged to the front end of the main body of the lifting component 1 and the lifting component 2.

[0015] Furthermore, the lifting assembly 1 and the lifting assembly 2 have the same structure, and both include a first linear drive member and a fixing frame;

[0016] One end of the fixed frame is fixed to the tailstock of the linear drive component, and the other end serves as the tail end of the body and is hinged to the upper end of the main frame;

[0017] The output rods of the first linear drive members in the lifting assembly 1 and the lifting assembly 2 are respectively fixedly connected to the bag-supporting rod 1 and the bag-supporting rod 2;

[0018] The front seats of the first linear drive components in the lifting assembly 1 and the lifting assembly 2 serve as the front end of the body and are hinged to the two output ends of the bag-supporting assembly 1 and the bag-supporting assembly 2 respectively.

[0019] Furthermore, the bag-supporting assembly 1 and the bag-supporting assembly 2 have the same structure, and both include a second linear drive member and a third linear drive member;

[0020] The fixed ends of the second linear drive member and the third linear drive member in the bag support assembly 1 are respectively hinged to the outer wall of the front guard plate through the mounting shaft, and the fixed ends of the second linear drive member and the third linear drive member in the bag support assembly 2 are respectively hinged to the outer wall of the rear guard plate through the mounting shaft;

[0021] The front ends of the first linear drive members in lifting assembly 1 and lifting assembly 2 are respectively fixed with connecting plates 1 and 2, which serve as front seats of the first linear drive members in lifting assembly 1 and lifting assembly 2, and are hinged to the output ends of the second linear drive members and the third linear drive members in bag supporting assembly 1 and bag supporting assembly 2, respectively.

[0026] Furthermore, two limit plates are installed on the main frame; the two limit plates are respectively located on both sides of the first linear drive component in lifting component one and lifting component two along the width direction of the main frame, and are used to limit the displacement of the first linear drive component in lifting component one and lifting component two along the width direction of the main frame.

[0027] Furthermore, the two limiting plates are respectively mounted on the main frame through their mounting seats.

[0028] The beneficial effects of the utility model are:

[0029] 1. The utility model directly connects the bag-supporting rod to the output end of the lifting assembly. Compared with the previous structure, the output end of the lifting assembly needs to drive the bag-supporting rod frame to move up and down, eliminating the bag-supporting rod frame, greatly reducing the load weight of the output end of the lifting assembly, greatly simplifying the structure, and improving the reliability of the lifting assembly.

[0030] 2. The bag-holding mechanism in the present invention uses the second and third linear drive members to drive the lifting assembly, and the first linear drive member is rotated by the fixed frame shaft to achieve left and right tilting and swinging, and the bag-holding rod is driven by the first linear drive member to jointly complete the bag-holding action.

[0031] 3. In the lifting assembly of the utility model, the lower end of the fixed frame is fixedly connected to the first linear drive member, and the upper end of the fixed frame is hinged to the main frame. The bag-supporting rod does not need to be kept in a vertical state all the time during operation, but can still support the bag, which makes the structure simpler and more economical.
