Description

Technical Field

[0001] The present invention relates to the technical field of tube material feeding devices, in particular to a packaging and feeding device for special-shaped bar tubes. Background Art

[0002] The liquid storage end of the vaginal applicator is generally provided with a plastic tube, through which the liquid medicine is delivered into the vagina. The plastic tube is generally a special-shaped structure, such as Figure 6 The tube body shown has a connection end for connecting to the applicator at one end and a spherical end for inserting into the vagina at the other end. Due to the special structure of the tube body, when feeding the packaging machine, the distribution direction of the tube body is always very disordered, and it needs to be manually aligned continuously, resulting in a significant reduction in the working efficiency of the packaging machine and an increase in the labor intensity of the workers. Summary of the Invention

[0003] The purpose of the present invention is to solve the problem in the prior art that tubes are always distributed disorderly when loading special-shaped tube packaging machines, resulting in reduced packaging efficiency, and to propose a special-shaped bar tube packaging and loading device.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] A packaging and feeding device for special-shaped bar and tube materials, including a circulating feeding mechanism, the circulating feeding mechanism having a surface body portion with a vertical ring cross-section and capable of rotation, the outer side surface of the surface body portion having evenly distributed strip grooves for accommodating bar and tube materials, at least one side of the surface body portion being an inclined surface, and the inclined surface moving obliquely upward, a bar and tube storage box being provided on the outer side of the inclined surface, and the side of the bar and tube storage box close to the inclined surface being open.

[0006] The circulating feeding mechanism includes two parallel chains and a sprocket for driving the chains to rotate. Several parallel cylindrical rods are connected between the two chains. Several cylindrical rods form the surface body part, and the strip grooves are formed between adjacent cylindrical rods.

[0007] The chain includes several unit sections, and two adjacent unit sections are defined as a first unit section and a second unit section. A connecting plate is provided between the first unit section and the second unit section. A support shaft is rotatably connected between the connecting plate and the first unit section, and between the connecting plate and the second unit section. The cylindrical rod is coaxially fixedly installed between the corresponding support shafts of the two chains.

[0008] A friction transmission mechanism is installed on the inner side of the inclined surface. The friction transmission mechanism includes a conveyor belt and a transmission roller for driving the conveyor belt to rotate. One side of the conveyor belt is frictionally transmitted with at least part of the cylindrical rod of the inclined surface.

[0009] A back plate is supported on the inner side of the belt portion of the conveyor belt that contacts the inclined surface, and the movement direction of the belt portion of the conveyor belt that contacts the inclined surface is opposite to the movement direction of the inclined portion.

[0010] The bar and tube storage box includes two vertically and parallel fixed side panels, one end of the fixed side panel is arranged close to the inclined portion, a movable panel is provided between the two fixed side panels, the movable panel is arranged perpendicular to the fixed side panel, and the bottom end of the movable panel is rotatably connected to the fixed side panel via a rotating shaft. The bar and tube storage box also includes a power mechanism for driving the movable panel to swing repeatedly around the rotating shaft.

[0011] The distance between adjacent fixed side plates is equal to or slightly about the length of the bar tube.

[0012] It also includes a material blocking plate, and a limiting channel is formed between the material blocking plate and at least a part of the surface body.

[0013] The present invention proposes a special-shaped bar tube packaging and loading device, which has the beneficial effect of placing the bar tube into the tube body storage cavity of the bar tube storage box. Since the side of the bar tube storage box close to the inclined surface is open, the bar tube portion will be supported on the inclined portion, and the outer side surface of the surface body portion has evenly distributed strip grooves for accommodating the bar tube. As the surface body portion rotates, the inclined surface moves obliquely upward, and the strip groove moves from bottom to top. The bar tube falls into the strip groove and moves to other workstations along the strip groove. Using this structure for loading can make the transportation of the bar tube more orderly.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-6 A special-shaped bar and tube packaging and feeding device includes a circulating feeding mechanism 2, which has a surface body portion 20 with a vertical ring cross-section and can be rotated. The outer side of the surface body portion 20 has evenly distributed strip grooves 21 for accommodating bar tubes 22. At least one side of the surface body portion 20 is an inclined surface 19, and the inclined surface 19 moves obliquely upward. A bar tube storage box 23 is provided on the outside of the inclined surface 19, and the side of the bar tube storage box close to the inclined surface 19 is open.

[0023] Place the bar tube into the tube body storage cavity 3 of the bar tube storage box 23. Since the side of the bar tube storage box close to the inclined surface 19 is open, the bar tube 22 will be partially supported on the inclined portion 19. The outer side surface of the surface body 20 has evenly distributed strip grooves 21 for accommodating the bar tube 22. As the surface body 20 rotates, the inclined surface 19 moves obliquely upward, and the strip groove 21 moves from bottom to top. The bar tube falls into the strip groove 21 and moves to other workstations along the strip groove. Using this structure for loading can make the bar tube transportation more orderly.

[0024] As an embodiment, a shift plate can be provided at the end of the conveying position of the inclined portion 19 , and the distance between the shift plate and the inclined portion 19 is only enough for one bar tube 22 to pass through, thereby avoiding carrying excess bar tubes 22 between adjacent bar tubes 22 .

[0025] As an embodiment, the surface portion 20 is a conveyor belt, and the outer surface of the conveyor belt is provided with evenly distributed strip grooves 21. The conveyor belt can be a rubber belt, and the strip grooves 21 are provided on the surface of the rubber belt.

[0026] As a preferred embodiment: the bar tube storage box 23 includes two vertically and parallel fixed side panels 5, one end of the fixed side panel 5 is arranged close to the inclined portion 19, a movable panel 4 is provided between the two fixed side panels 5, the movable panel 4 is arranged vertically to the fixed side panel 5, and the bottom end of the movable panel 4 is rotatably connected to the fixed side panel 5 via a rotating shaft 7. The bar tube storage box 23 also includes a power mechanism for driving the movable panel 4 to repeatedly swing around the rotating shaft 7. The bar tube is placed in the tube body storage cavity 3, and the movable panel 4 is driven to swing repeatedly by the power mechanism. When the movable panel 4 swings, it will repeatedly squeeze and push the tube body storage cavity 3, the rotating shaft 7 is parallel to the strip groove 21, that is, the movable plate 4 repeatedly moves toward the inclined portion 19. When the movable plate 4 approaches the inclined portion 19, the top opening of the tube storage cavity 3 gradually becomes smaller, and the internal bar tubes 22 are squeezed and gradually gather upward. When the movable plate 4 moves away from the inclined portion 19, the bar tubes 22 fall downward under the action of gravity. The repeated squeezing and relaxation, repeated rising and falling of the bar tubes are conducive to the bar tubes 22 falling into the strip groove 21 on the one hand, and on the other hand, it is conducive to making the bar tubes 22 more orderly arranged in the tube storage cavity 3.

[0027] The power mechanism can use power elements such as air cylinders, hydraulic cylinders, and electro-hydraulic push rods to drive the movable plate 4 to repeatedly swing around the rotating shaft 7.

[0028] The distance between adjacent fixed side plates 5 is equal to or slightly about the length of the bar tube 22, which can better limit the bar tube, make the bar tube more orderly when repeatedly squeezed and relaxed, and repeatedly rise and fall, and make the bar tube more orderly distributed in the tube body storage cavity 3.

[0029] refer to Figure 3 , also includes a baffle plate 1, a limiting channel 12 is formed between the baffle plate 1 and at least part of the surface body 20, and the limiting effect of the baffle plate 1 can ensure the stable transmission of the bar tube 22 in the vertical direction.

[0030] As an implementation method, refer to Figure 3 、 Figure 4 、 Figure 5The circulating feeding mechanism 2 includes two parallel chains 18 and a sprocket 11 for driving the chains 18 to rotate. A plurality of parallel cylindrical rods 17 are connected between the two chains 18. The plurality of cylindrical rods 17 form a surface portion 20. A strip groove 21 is formed between adjacent cylindrical rods 17. The strip groove 21 is formed by the cooperation between the chain and the cylindrical rods 17. The chain 18 includes a plurality of unit sections, and two adjacent unit sections are defined as a first unit section 13 and a second unit section 15. A connecting plate 14 is provided between the first unit section 13 and the second unit section 15. A support shaft 16 is rotatably connected between the connecting plate 14 and the first unit section 13, and between the connecting plate 14 and the second unit section 15. The cylindrical rod 17 is coaxially fixedly installed between the corresponding support shafts 16 of the two chains 18, so that the cylindrical rod 17 can rotate relative to the chain 18.

[0031] refer to Figure 3 、 Figure 5 A friction transmission mechanism 6 is installed on the inner side of the inclined surface 19. The friction transmission mechanism 6 includes a conveyor belt 9 and a transmission roller 10 for driving the conveyor belt 9 to rotate. One side of the conveyor belt 9 is frictionally driven with at least part of the cylindrical rod 17 of the inclined surface 19. The inner side of the belt portion of the conveyor belt 9 that contacts the inclined surface 19 is supported by a back plate 8. The movement direction of the belt portion of the conveyor belt 9 that contacts the inclined surface 19 is opposite to the movement direction of the inclined portion 19. When the surface portion 20 rotates, the inclined surface 19 moves upward, and the cylindrical rod 17 moves upward following the chain. When the cylindrical rod 17 is driven by the conveyor belt 9 to rotate clockwise under the action of friction, the bar tube 22 is subjected to downward gravity, and the cylindrical rod 17 below the bar tube 22 can give the bar tube 22 an oblique upward thrust when rotating clockwise. The cylindrical rod 17 that moves upward and rotates can better make the bar tube 22 fall into the strip groove and make the bar tube 22 be transported in the strip groove 21 in an orderly manner. At the same time, the rotating cylindrical rod 17 is conducive to promoting the orderly distribution of the bar tubes in the tube body storage cavity 3.

[0032] When the bar tube is packaged, it is necessary to use a push rod to push the bar tube out of the limiting channel 12 along the direction of the strip groove 21. In order to prevent the chain 18 from preventing the bar tube from escaping from the cylindrical rod 17, the diameter of the cylindrical rod is greater than the thickness of the chain 18.

[0033] The above is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technical solution, conception, and design obtained by equivalent replacement or modification of the technical solution and inventive concept of the present invention by any technician familiar with this technical field within the technical scope disclosed by the present invention should be covered by the scope of protection of the present invention.
