Description

Technical Field

[0001] The utility model belongs to the technical field of ton bag packaging, and particularly relates to a bag clamping detection mechanism of a ton bag packaging machine. Background Art

[0002] A ton bag is a flexible transportation packaging container. It has the advantages of moisture-proof, dust-proof, radiation-resistant, firm and safe, and has sufficient strength in structure; due to the convenient loading, unloading and handling of the flexible intermediate bulk container, the loading and unloading efficiency is significantly improved, and it has developed rapidly in recent years. The flexible intermediate bulk container is generally woven from polyester fibers such as polypropylene and polyethylene. When in use, the ton bag needs to be sleeved outside the product discharge pipe, and a bag clamping device is used to make it closely adhere to the outside of the discharge pipe to facilitate the product to enter the ton bag.

[0003] In the Chinese patent with the publication number of CN220199762U, a bag clamping detection mechanism of a ton bag packaging machine is mentioned. When the bag clamping assembly completes clamping, the pressing rod just presses the button, so that the indicator light emits a prompt light, indicating that the bag clamping is completed, thus playing a good role in automatic detection. Then, it can be discharged and packaged through the discharge chute and the discharge port, avoiding the situation that the bag falls off due to insufficient clamping and not being detected in time.

[0004] The bag clamping detection mechanism of the ton bag packaging machine in the above-mentioned prior art only clamps the left and right sides of the ton bag, and leakage or powder spraying is still likely to occur on the front and back sides. In addition, when the worker clamps the ton bag, the start of the clamping device cannot be detected in time, so it is easy to injure the hand, and the safety is poor. Therefore, we propose a bag clamping detection mechanism of a ton bag packaging machine. Content of the Utility Model

[0005] The purpose of the utility model is to provide a bag clamping detection mechanism of a ton bag packaging machine to solve the problems existing in the prior art that only the left and right sides of the ton bag are clamped, and leakage or powder spraying is still likely to occur on the front and back sides; the start of the clamping device cannot be detected in time, and it is easy to injure the hand.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A bag clamping detection mechanism of a ton bag packaging machine includes a discharge pipe. A fixed seat is fixedly connected to the outside of the discharge pipe.

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Refer to Figures 1-6 As shown in the figure, the present utility model provides a bag clamping detection mechanism for a ton bag packaging machine, including a discharge pipe 1, a fixed seat 3 fixedly connected to the outer side of the discharge pipe 1, a bag clamping detection component 2 arranged on the outer side of the discharge pipe 1, and a protection component 4 arranged on the outer side of the discharge pipe 1;

[0029] The bag clamping detection component 2 includes two clamping strips 203 symmetrically arranged on the outer side of the discharge pipe 1. A cylinder 205 is fixedly connected to the top of the fixed seat 3. The telescopic end of the cylinder 205 is fixedly connected to a semi-circular ring 201. Two symmetrically distributed rectangular rods 206 are fixedly connected to the bottom of the semi-circular ring 201. The bottom end of the rectangular rod 206 is movably connected to a mounting rod 207 through a pin shaft. An inclined rod 208 is movably connected to the outer side of the discharge pipe 1 through a pin shaft. A rubber strip 210 is fixedly connected to the inner side of the clamping strip 203.

[0030] In a further embodiment, referring to Figures 1-5 , two symmetrically distributed fixing blocks 202 are fixedly connected to the outer side of the discharge pipe 1. A through rectangular hole 211 is formed in the top of the fixing block 202. Under the action of the fixing block 202 and the rectangular hole 211, the movement track of the rectangular rod 206 is restricted to ensure that it can only move in the up and down directions. The rectangular rod 206 is slidably connected to the inner side of the rectangular hole 211. A connecting block 204 is fixedly connected to the bottom end of the mounting rod 207. The connecting block 204 facilitates the connection between the mounting rod 207 and the clamping strip 203. The connecting block 204 is fixedly connected to the outer side of the clamping strip 203. A through activity groove 209 is formed in the outer side of the mounting rod 207. The formation of the activity groove 209 facilitates the inclined rod 208 to extend into the activity groove 209, and the inclined rod 208 can move in the activity groove 209. When the mounting rod 207 moves upward, at this time, under the action of the inclined rod 208, the bottom end of the mounting rod 207 can be opened outward, so that the clamping strip 203 is opened, facilitating the loading and unloading of the ton bag. The other end of the inclined rod 208 is movably connected to the inner side of the activity groove 209 through a pin shaft.

[0031] In this embodiment, the opening and closing operations of the two clamping strips 203 can be controlled by the air cylinder 205. Through the two clamping strips 203, the feeding port of the ton bag can be closely attached to the outer side of the discharge pipe 1, and there will be no leakage and powder spraying phenomena.

[0032] In a further embodiment, referring to Figures 1-5 , an electrode connector 213 is fixedly connected to the top of the clamping strip 203. The electrode connectors 213 are provided in two groups, respectively arranged at both ends of the clamping strip 203. An indicator light 212 is fixedly connected to the rear side of the fixed seat 3. The indicator light 212 is electrically connected to the electrode connector 213. When the two clamping strips 203 are clamped, the electrode connectors 213 on both sides are in contact. At this time, the circuit of the indicator light 212 is in a connected state, and the indicator light 212 lights up. It should be noted that the connection method between the indicator light 212 and the electrode connector 213 is an existing technical means and will not be described in detail again.

[0033] In this embodiment, after the ton bag is clamped from the outside by the clamping strip 203, the clamping state of the ton bag packaging machine can be detected through the indicator light 212.

[0034] In a further embodiment, referring to Figures 1-6The protective component 4 includes a bracket 401 movably connected to the outer side of the discharge pipe 1 through a pin shaft. The bracket 401 can be flipped in the up and down directions under the action of the pin shaft. When the clamping strip 203 is opened, the end of the bracket 401 away from the discharge pipe 1 can be pushed to flip upward. At this time, the connector 404 is not in contact with the power connector 402. When the opened clamping strip 203 begins to close, the bracket 401 loses its limit and flips downward. The connector 404 contacts the power connector 402. A buzzer 403 is fixedly connected to the outer side of the fixing seat 3. The buzzer 403 makes a sound after the circuit is connected to remind the staff that a connector 404 is provided on the outer side of the bracket 401, and a power connector 402 is provided on the outer side of the discharge pipe 1. The buzzer 403 is electrically connected to the connector 404. It should be noted that the connection method between the buzzer 403, the connector 404 and the power connector 402 is a prior art means and will not be described in detail again.

[0035] In this embodiment, when the ton bag entraining assembly is working, the bracket 401 moves downward under the action of gravity, and the connector 404 set on the outside of the bracket 401 contacts the power connector 402. At this time, the buzzer 403 makes a sound to remind the staff to start the bag clamping operation to avoid hand injuries.

[0036] The working principle of the utility model is as follows:

[0037] When the ton bag packaging machine is in use, the cylinder 205 is started, and the cylinder 205 extends to push the semicircular ring 201, the rectangular rod 206 and the installation rod 207 to move upward, and the two sets of clamping strips 203 are opened under the action of the inclined rod 208. At the same time, the opening of the clamping strips 203 pushes the bracket 401 to flip upward, so that the connector 1 404 is away from the power connector 402;

[0038] At this time, the feed port of the ton bag can be sleeved on the outside of the discharge pipe 1. After the sleeve is completed, the cylinder 205 is contracted. The cylinder 205 contracts through the semicircular ring 201, the rectangular rod 206 and the installation rod 207 to make the two groups of clamping strips 203 converge to the middle, and finally form a ring, which clamps the ton bag outside the discharge pipe 1. When the two ends of the two clamping strips 203 are in contact, the two electrode connectors 213 are in contact, and the indicator light 212 is on, indicating that the ton bag packaging machine has completed the bag clamping;

[0039] During the clamping operation, when the clamping strip 203 performs a polymerization operation, the bracket 401 loses the limit from the clamping strip 203 and flips downward under the action of gravity until the connector 404 on the outside of the bracket 401 contacts the power connector 402 on the outside of the discharge pipe 1. At this time, the buzzer 403 sounds to remind the staff to prevent pinching.

[0040] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
