[0003] The winding packaging of the two assemblies means that a plurality of assemblies are sequentially wound around a central shaft to form a compact packaging structure. This packaging method not only saves space, but also facilitates transportation and storage. In addition, winding packaging can prevent the assemblies from being damaged during transportation and use.

[0004] Since the intravenous needle fine catheter assembly and the blood taking needle fine catheter assembly are widely used in the medical field, the demand for their winding packaging equipment is also increasing. There are more and more suppliers of winding packaging equipment on the market, and the competition is becoming more and more fierce. In order to occupy a favorable position in the market, suppliers need to continuously improve the production efficiency of equipment and reduce the cost of equipment.

Among them, the structure is complicated and needs to be moved and transported many times during bagging, and the completed winding materials need to be transported a long distance, which is not conducive to efficient production and may cause errors during transportation, affecting overall efficiency. The production workshop for storing medical consumable production equipment is high in cost, and the large size of the equipment is not conducive to market competition, and the large size and complex structure also increase the cost.

The winding product transfer assembly 200 is slidingly arranged on a mounting frame 110, used to clamp the winding completed material and transfer the material to the transfer bagging mechanism 300 and the bag opening mechanism 500; the transfer bagging mechanism 300 comprises a clamping assembly 310 and a shape limiting member 308, the clamping assembly 310 pulls the transferred material into the shape limiting member 308 to limit the winding shape of the material, the shape limiting member 308 transfers the material to the bag opening of the packaging bag of the bag opening mechanism 500, and the clamping assembly 310 pushes the material into the packaging bag, referring to Figure 7 The bag opening mechanism 500 is arranged in the moving direction of the shape limiting member 308, used to open the bag opening of the packaging bag so that the shape limiting member 308 can extend into the bag opening of the packaging bag; the bag transfer mechanism 400 is slidingly arranged on the mounting frame 110, used to transfer the packaging bag to the bag opening mechanism 500; the guide assembly 700 is located between the transfer bagging mechanism 300 and the bag opening mechanism 500, the guide member 702 of the guide assembly 700 has a guide track gradually narrowing from a wide entrance to a narrow exit, one end of the narrow exit faces the shape limiting member 308, and the guide member 702 can avoid the moving track of the shape limiting member 308, referring to Figure 3 The positions of the transfer bagging mechanism 300 and the bag opening mechanism 500 are arranged close to each other, so that after the transfer bagging mechanism 300 clamps the material transferred by the winding product transfer assembly 200, the transfer bagging mechanism sends the material into the packaging bag of the bag opening mechanism, simplifying the bagging process, reducing the transfer time, and improving the bagging efficiency.

[0069] Further, referring to Figure 2, the winding product conveying assembly 200 comprises a moving plate 201, a lifting assembly 202, a mounting plate 203, a jaw cylinder 204 and a finger clamp 205; the moving plate 201 is slidingly arranged on the mounting frame 110 and can be driven to move, the lifting assembly 202 is arranged on the moving plate 201, the lifting assembly 202 comprises a linear bearing, a guide rod and a linear cylinder, the linear bearing and the linear cylinder are fixedly arranged on the moving plate 201, the guide rod can slide up and down in the vertical direction through the linear bearing, the guide rod and the linear bearing can have a plurality of guide rods, one end of the downward guide rod is fixedly connected with the mounting plate 203, the extending rod of the linear cylinder is connected with the mounting plate 203, the mounting plate 203 is provided with the jaw cylinder 204, two driving ends of the jaw cylinder 204 are fixedly connected with the finger clamp 205 respectively, and the two finger clamps 205 are driven by the jaw cylinder 204 to approach and clamp the winding completed material.

[0070] Further, referring to Figure 3 , the moving plate 301 in the moving and transporting bagging mechanism 300 is slidingly arranged on the support frame 130 through the sliding rail assembly 302, and the support frame 130 is fixedly connected to the workbench 100. The translation cylinder 303 is fixedly arranged on the support frame 130, and the driving end of the translation cylinder 303 is connected with the moving plate 301. The moving plate 301 can be driven by the translation cylinder 303 to translate to approach or move away from the bag opening mechanism 500. The shape limiting piece 308 is fixedly arranged on the moving plate 301, is located on the side close to the bag opening mechanism 500, and is arranged towards the bag opening mechanism 500. The shape limiting piece 308 can adopt a cylindrical shape or a square shape or other shapes. The moving plate 304 is slidingly arranged on the moving plate 301 through the sliding rail assembly 305, the translation cylinder 306 is fixedly arranged on the moving plate 301, the driving end of the translation cylinder 306 is connected with the moving plate 304, and the moving plate 304 can be driven by the translation cylinder 306 to translate to approach or move away from the bag opening mechanism 500. The mounting rod 309 and the opening and closing cylinder 311 are fixedly arranged on the moving plate 304, the clamping assembly 310 is arranged on one end of the mounting rod 309 close to the bag opening mechanism 500, the mounting rod 309 and the clamping assembly 310 pass through the shape limiting piece 308, the clamping assembly has two clamping pieces that can approach or move away from each other, the two clamping pieces are hinged to the mounting rod 309, and the opening and closing cylinder 311 drives the clamping assembly 310 to clamp or open through the movement of the driving rod 312. The two clamping pieces are similar to the structure of scissors, and the driving rod 312 is connected to the handle of the scissors, and linear motion is converted into rotation through the connecting rod structure.

[0071] More preferably, referring to Figure 4 , the shape limiting piece 308 has a round cornered long prism shape, and the four corners of the cross section are rounded, like the four corners of a rhombus are rounded, the round corners of the shape limiting piece 308 are arranged upwards and downwards and horizontally, the shape limiting piece 308 is arranged on the moving plate 301, and the shape limiting piece 308 is arranged on the moving plate 301.Figure 4 The two horizontal corners are larger than the two vertical corners, because the clamping assembly 310 clamps the square shape of the rolled material horizontally, so the shape limiting member 308 can have the maximum width to place the rolled material, while the vertical space is used to accommodate the clamping assembly and the mounting rod 309. By designing the shape of the shape limiting member as a rhombus with rounded corners, the maximum size of the opened bag is utilized. The problem of the large size of the blade material being stuck in the shape limiting member after rolling is solved, realizing the transportation and loading of the large size of the blade material into the bag.

[0072] Further, referring to Figure 3 and Figure 4 , the guide assembly 700 further comprises a mounting member 701 and a lifting cylinder 703, the mounting member 701 is vertically slidingly arranged on the support frame 130 and vertically slidingly relative to the workbench 100, the guide member 702 is fixedly arranged on the top of the mounting member 701, the lifting cylinder 703 is fixedly connected to the workbench 100, the driving end of the lifting cylinder 703 is connected to the mounting member 701, and the lifting cylinder 703 drives the guide member 702 to move up and down. In this way, when the finger clamp 205 of the rolling product transfer mechanism transfers the material between the material transfer and bagging mechanism 300 and the bag opening mechanism 500, the lifting cylinder 703 has already pushed the guide member 702 to the highest position, so that the narrow outlet of the guide member is aligned with the shape limiting member 308. Then the clamping assembly 310 extends from the shape limiting member 308, passes through the guide track of the guide member 702 from the narrow outlet to the material clamped by the finger clamp 205, and after the clamping assembly 310 clamps the material, the material is pulled into the guide track from the wide inlet of the guide member 702 and then pulled out from the narrow outlet to enter the inside of the shape limiting member 308. The shape of one end of the narrow outlet of the guide member 702 matches the shape of the shape limiting member 308, when the shape limiting member 308 is in the shape of a cylinder, the shape of one end of the narrow outlet of the guide member 702 is circular, and when the shape limiting member 308 is in the shape of a long rectangular prism with rounded corners, the shape of one end of the narrow outlet of the guide member 702 is a rhombus. When the shape limiting member 308 moves towards the bag opening mechanism 500, the guide member 702 moves downward to avoid the shape limiting member 308. It can be understood that, in addition to avoiding the shape limiting member 308 by lifting, the guide member 702 can also be fixedly arranged, and the size of the narrow outlet of the guide member 702 is larger than the shape limiting member 308, so that the shape limiting member 308 can pass through the middle of the guide member 702, thereby avoiding the movement track of the shape limiting member 308.

The upper extrusion part comprises a moving plate five 601, a lifting assembly three 602, a mounting plate three 603, a bag pressing cylinder one 604 and a bag pressing part one 605; the lower extrusion part comprises a guide seat 606, a guide rod 607, a mounting plate four 608, a bag pressing part two 609 and a bag pressing cylinder two 610.
