Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of clamping mechanisms for expansion bag filling machines, specifically a clamping mechanism for an expansion bag filling machine. Background Technology
[0002] As is well known, an expansion bag filling machine is a machine that can fill and seal liquid food, medicine and other items into expansion bags. Due to its high automation, high efficiency and clean production process, it is widely used in food filling companies.
[0003] However, it has been found in use that, since the expansion bag is made of soft plastic, it is not easy to fix. During the process of clamping and filling the expansion bag, the expansion bag is prone to displacement or even falling out of the filling head due to the lack of secure fixation, which affects the filling of the expansion bag. Therefore, we propose a clamping mechanism for the expansion bag filling machine to solve the above problems. Utility Model Content

Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-4This utility model discloses a clamping mechanism for an expansion bag filling machine, comprising a support frame 1, a telescopic filling pipe 2 for the filling machine at the rear end of the support frame 1, an expansion bag placement platform 3 at the top end of the support frame 1, a conveying port 4 at the bottom end of the expansion bag placement platform 3, an air suction pump 5 at the front end of the bottom end of the support frame 1, the air suction pump 5 having several soft rubber suction tubes 6, each soft rubber suction tube 6 having a soft rubber head at its tip, so that the soft rubber suction tubes 6 of the clamping mechanism of the expansion bag filling machine can easily suck up the expansion bag, and a first telescopic cylinder 7 at the front end of the bottom end of the support frame 1. The first telescopic cylinder 7 has a nozzle clamping plate 8 at its telescopic end. The telescopic end of the first telescopic cylinder 7 cooperates with the nozzle clamping plate 8 in a fixed fit, allowing the first telescopic cylinder 7 to drive the nozzle clamping plate 8 to extend and retract. The nozzle clamping plate 8 is fixedly connected to several soft rubber suction tubes 6. A second telescopic cylinder 9 is located at the rear bottom of the support frame 1. The telescopic end of the second telescopic cylinder 9 has an L-shaped positioning clamping plate 10. The telescopic end of the second telescopic cylinder 9 cooperates with the L-shaped positioning clamping plate 10 in a fixed fit. In this arrangement, the extension end of the second telescopic cylinder 9 is fixedly fitted with the L-shaped positioning clamp 10, allowing the second telescopic cylinder 9 to drive the L-shaped positioning clamp 10 to extend and retract. A third telescopic cylinder 11 is located at the rear end of the second telescopic cylinder 9, and a positioning clamp 12 is located at the extension end of the third telescopic cylinder 11. The third telescopic cylinder 11 and the positioning clamp 12 are fixedly fitted, allowing the third telescopic cylinder 11 to drive the positioning clamp 12 to extend and retract. (Support frame 1...) The edges of the filling machine's telescopic filling tube 2, expansion bag placement platform 3, conveying port 4, suction pump 5, soft rubber suction tube 6, first telescopic cylinder 7, air nozzle clamping plate 8, second telescopic cylinder 9, L-shaped positioning clamping plate 10, third telescopic cylinder 11, and positioning clamping block 12 are all rounded, so that the clamping mechanism of the expansion bag filling machine will not scratch the user during use. The clamping mechanism of the expansion bag filling machine is not easy to shift due to the expansion bag not being securely fixed during the filling process, so that it will not affect the filling of the expansion bag.
[0023] In summary, the clamping mechanism of this expansion bag filling machine, during use, first places the expansion bag to be filled on the expansion bag placement platform 3. During the filling process, the first telescopic cylinder 7 drives the air nozzle clamping plate 8 and several soft rubber suction tubes 6 to extend and rise, so that the soft rubber suction tubes 6 contact the expansion bag at the bottom of the conveying port 4. The suction pump 5 is turned on, so that the soft rubber suction tubes 6 apply suction to the bottom of the expansion bag, sucking it into the bottom of the conveying port 4. Then, the second telescopic cylinder 9 is turned on, causing it to adjust the L-shaped positioning clamping plate 10 to retract downward, thereby positioning the positioning piece at the front end of the expansion bag filling port. Then, the third telescopic cylinder 11 is turned on, causing it to drive the positioning clamping block 12 to retract, and the L-shaped positioning clamping plate 10 and the positioning clamping block 12 hold the expansion bag in place. The positioning plate at the front end of the expansion bag filling port is clamped. At this time, the suction pump 5 is adjusted to release the suction force applied to the expansion bag by the soft rubber suction tube 6. The positioning plate at the front end of the expansion bag filling port is clamped by the L-shaped positioning clamp 10 and the positioning clamp 12, thereby positioning the expansion bag. The expansion bag is then filled by the expansion bag through the telescopic filling tube 2 of the filling machine. After filling is completed, the bag is sealed by the sealing mechanism of the filling machine. After filling is completed, each component is reset in sequence. Repeating the above steps can achieve automatic clamping and filling. The clamping mechanism of the expansion bag filling machine is not easy to shift due to the insecure fixation of the expansion bag during the clamping and filling process, so that it will not affect the filling of the expansion bag by the expansion bag filling machine. The clamping mechanism of the expansion bag filling machine has a better performance.
