Description

TECHNICAL FIELD

[0001] The utility model relates to packing equipment technical field, concretely is a carrying mechanism. BACKGROUND

[0002] In the production and packaging of various products, the carrying operation of the product, the packaging piece for the product and the packaged product is often involved. For example, paper boxes as commonly used packaging industrial products have been widely used in different products in various fields. In the modern industrial production of many products, automatic equipment is usually used to realize the packaging of products by paper boxes and the packaging of paper boxes. Taking a boxed disposable glove as an example, in its packaging production line, the cooperation of sealing box equipment, boxing equipment and conveying equipment is generally required. However, in most traditional packaging production lines, the conveying equipment generally works horizontally, that is, it realizes the circulation of paper boxes between various process equipment in the horizontal direction. For example, a latex glove automatic boxing packaging line provided by the patent with publication number CN115583381A. This horizontal arrangement has the problems of large space occupation and high construction cost, which needs to be optimized and improved.

[0003] Therefore, a vertical carrying scheme appears in the market, that is, various processes of product packaging are arranged in the vertical direction in sequence, which can effectively overcome the disadvantages of the horizontal carrying scheme. Further, the patent with publication number CN220483732U proposes a packaging box lifting device for the vertical packaging scheme, which can sequentially lift the packaging box in the vertical direction to realize the circulation of the packaging box between various stations. However, most of the existing lifting (carrying) devices including the patent still have the limitations of unreasonable design and complex structure. Specifically, in the packaging box lifting device proposed by the patent, a plurality of structures are arranged, including a clamping arm, a lifting mechanism for driving the clamping arm to lift as a whole, a driving device on the clamping arm, an inner clamping plate and an upper clamping plate on the inner clamping plate, an outer clamping plate and a lower clamping plate on the outer clamping plate. In use, the lifting mechanism can only lift the clamping arm and the structures thereon synchronously, and the distance between the upper clamping plate and the lower clamping plate needs to be adjusted separately by the driving device. Therefore, the load of the lifting mechanism is large, so the lifting difficulty is high, the stability is low, and the structure is complicated, which is not convenient for efficient control of the distance between the upper clamping plate and the lower clamping plate.

[0004] In view of the above, the utility model provides a carrying mechanism. UTILITY MODEL CONTENTS

[0034] In the embodiment, one upper limiting baffle 17 is arranged on one side of the upper clamping plate 1 close to the lower clamping plate 2 (in other embodiments, other numbers can be arranged according to actual conditions, as long as the upper limiting baffle 17 can block and limit the paper box without affecting the clamping of the paper box, the number of the lower limiting baffle 18 is consistent with that of the upper limiting baffle 17), and one lower limiting baffle 18 is arranged on one side of the lower clamping plate 2 close to the upper clamping plate 1; the positions of the upper limiting baffle 17 and the lower limiting baffle 18 correspond to each other and are close to the direction in which the two clamping plate mounting frames are located; the upper limiting baffle 17 and the lower limiting baffle 18 are both in a tooth shape (in other embodiments, a wave shape, a claw shape or other feasible structures can be arranged according to actual conditions, and the utility model does not specially limit this), and the teeth in the upper limiting baffle 17 and the teeth in the lower limiting baffle 18 are arranged in an interval staggered manner.

[0035] In the embodiment, the upper clamping plate 1 is provided as an elastic clamping plate (in other embodiments, the lower clamping plate 2 can be provided as an elastic clamping plate according to actual conditions, and the utility model does not specially limit this), specifically including a fixed plate 15 and a floating plate 16, the floating plate 16 is located below the fixed plate 15, and the fixed plate 15 is fixedly connected to the upper clamping plate mounting frame 3; a guide rod 19 is fixedly connected to the upper surface of the floating plate 16, the guide rod 19 is connected with a limiting piece 21 after sliding through the hole provided at the corresponding position of the fixed plate 15, the limiting piece 21 is connected with the guide rod 19, and the lower surface of the limiting piece 21 has an area greater than the cross-sectional area of the hole; the outer side of the guide rod 19 between the fixed plate 15 and the floating plate 16 is sleeved with a spring 20, and the two ends of the spring 20 are respectively connected or contacted with the fixed plate 15 and the floating plate 16.

[0036] Based on the above structure, the working principle of the conveying mechanism in the embodiment is as follows:

[0037] The upper clamping plate 1 and the lower clamping plate 2 are respectively driven to lift by the respective lifting drive mechanisms, on the one hand, the upper clamping plate 1 or the lower clamping plate 2 can be individually driven to lift to flexibly adjust the height distance between the upper clamping plate 1 and the lower clamping plate 2, thereby realizing clamping and releasing of the carton; on the other hand, the upper clamping plate 1 and the lower clamping plate 2 can be driven together to lift synchronously to synchronously adjust the height positions of the upper clamping plate 1 and the lower clamping plate 2, thereby realizing lifting of the clamping station and the carton thereon. In addition, the horizontal movement of the overall structure on the mounting plate 6 can be realized by the translation drive mechanism, so as to realize the circulation of the carton between different process stations.

[0038] Among them:

[0039] When the lifting drive mechanism drives the lifting movement, the lifting drive motor 5 drives the pulley to rotate, so as to drive the belt 7 part on both sides of the pulley to lift (in the conveying mechanism, the belt 7 part on both sides of the pulley only lifts on the fixed side, and does not make complete rotary movement around the pulley), thereby making the transmission member 13 on the belt 7 part lift, so as to drive the clamping plate mounting frame to lift. When the translation drive mechanism drives the translation movement, the translation drive motor 14 drives the synchronous pulley to rotate, so as to drive the lead screw 10 to rotate, thereby making the nut seat 9 on the lead screw 10 translate, so as to drive the mounting plate 6 to translate.

[0040] The upper limiting baffle 17 and the lower limiting baffle 18 can limit and block the paper box when clamping the paper box; the upper limiting baffle 17 and the lower limiting baffle 18 can adapt to the mutual approach or separation between the upper clamping plate 1 and the lower clamping plate 2 through the interval staggered arrangement of the teeth, that is, the two limiting baffles do not interfere with each other when approaching each other, and the limiting and blocking effect can be achieved when moving away from each other. The upper clamping plate 1 is arranged as an elastic clamping plate, so that the floating plate 16 can be in elastic contact with the upper surface of the paper box under the action of the spring 20 when clamping the paper box, thereby avoiding damage to the paper box caused by rigid contact.

[0041] Based on the above principle, various specific carrying modes can be carried out, and the following two modes are taken as examples:

[0042] Mode one:

[0043] 1) In the initial state, the upper clamping plate 1 and the lower clamping plate 2 are located at the initial position, which is located on one side of the paper box, and the height distance between the upper clamping plate 1 and the lower clamping plate 2 is greater than the height of the paper box; under the action of the translation driving mechanism, the upper clamping plate 1 and the lower clamping plate 2 are respectively translated to the upper and lower sides of the paper box;

[0047] 5) Under the action of the translation driving mechanism, the upper clamping plate 1 and the lower clamping plate 2 are respectively moved to the avoiding position;

[0048] 6) Under the action of the corresponding lifting driving mechanism, the upper clamping plate 1 and the lower clamping plate 2 descend (or ascend) synchronously to return to the initial position and wait for the next carrying cycle.

[0051] 2) under the action of corresponding lifting driving mechanism, the upper clamping plate 1 and the lower clamping plate 2 act simultaneously, the upper clamping plate 1 is lowered, the lower clamping plate 2 is raised to hold the carton, and the carton is released at the current station;

[0052] 3) under the action of the translation driving mechanism, the upper clamping plate 1 and the lower clamping plate 2 are translated back to the initial position with the carton;

[0053] 4) under the action of corresponding lifting driving mechanism, the upper clamping plate 1 and the lower clamping plate 2 are raised (or lowered) synchronously to carry the carton to the avoiding position;
