Description

Technical Field

[0001] The utility model relates to the field of automation, in particular to a tube needle packaging counting mechanism. Background Art

[0002] Acupuncture needles are acupuncture instruments in traditional Chinese medicine. In recent years, as traditional Chinese medicine treatment methods have gradually spread to the world, the use of acupuncture needles has also increased. At present, as disposable medical supplies, acupuncture needles must not only ensure their own product quality under fierce market competition, but also their packaging is very critical. This is because packaging will directly affect the product's sales cost, the safety and reliability of the transportation process, and the convenience of use.

[0003] There are two types of traditional acupuncture needle packaging. One is to directly place the acupuncture needle in a plastic bag, sterilize it, and then seal it, which is simple packaging; the other is to place the acupuncture needle in a plastic tube, sterilize it, and then package it in a packaging bag. The first simple packaging structure is characterized by simple packaging and the lowest cost, but the biggest problem is poor safety and reliability. During transportation, the acupuncture needle can easily pierce the packaging bag, causing the sterilization to fail, and it is also easy to cause damage to the needle tip. Therefore, the current mainstream packaging method is the second one.

[0004] The second packaging method requires that the acupuncture needles be placed into plastic tubes (commonly known as tube needles) and then placed into plastic bags in fixed quantities. However, manual counting is inefficient, so the conventional practice is to use the weighing principle for weighing and packaging. This method has low accuracy and cannot meet the requirements of precision technology. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a tube needle packaging counting mechanism, including a mounting seat, a material bin fixed on one side of the mounting seat for stacking tube needles, a counting component located below the material bin for counting tube needles, and a material storage component located below the counting component.

[0007] Preferably, the silo is a V-shaped structure with a feeding opening at the bottom, and the counting component is located below the feeding opening.

[0008] Preferably, a plurality of material-discharging shafts are arranged side by side at the material-discharging port, and the material-discharging shafts are controlled by a driving assembly installed on the other side of the mounting seat, so that the plurality of material-discharging shafts rotate in the same direction, so that the tube needles stacked above the material-discharging shafts move downward into the counting assembly.

[0009] Preferably, the counting assembly includes a plurality of groups of counting wheels arranged side by side, and a blocking block arranged between two adjacent counting wheels. The counting wheels are controlled to rotate by a servo motor fixed on the other side of the mounting base, and each counting wheel corresponds to a servo motor. A plurality of arc grooves for accommodating tube needles are evenly spaced on the circumference of the side wall of the counting wheel.

[0010] Preferably, both side walls of the barrier block are arc-shaped structures that fit the counting wheel.

[0011] Preferably, the material storage assembly includes a fixed plate, a material storage hopper, an opening cylinder and a sliding assembly. The material storage hopper is divided into multiple groups, corresponding to multiple counting wheels respectively. The material storage hopper has two symmetrically arranged material baffle plates, one of which is fixed and connected to the fixed plate, and the other is movable and connected to the sliding assembly installed on the surface of the fixed plate. The sliding assembly is controlled by the opening cylinder at the end to achieve lateral movement, and the fixed material baffle plate and the movable material baffle plate are approached or separated from each other to achieve material storage or material dropping.

[0012] Preferably, both sides of the fixing plate are fixed on the mounting seat by lifting cylinders.

[0013] Compared with the prior art, the tube needle packaging counting mechanism disclosed by the utility model has the following beneficial effects: a material transfer shaft is arranged between the bottom of the hopper and the counting wheel as a buffer zone, which can ensure that the tube needles enter the counting wheel one by one to avoid accumulation and jamming; blocking blocks are arranged between the counting wheels to ensure the independent technology of each counting wheel and avoid displacement of the tube needles during rotation; the opening and closing storage hopper structure realizes rapid switching of storage and material discharge, thereby improving the flexibility of use; the entire mechanism can realize automatic counting and material discharge, ensuring the accuracy of counting tubes.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] The utility model provides a tube needle packaging counting mechanism, the structure of which is as follows Figures 1 to 3 As shown, it includes a mounting base 1, a silo 2 fixed on one side of the mounting base, a counting component 3 located below the silo, and a storage component 4 located below the counting component. The tube needles are stacked in the silo and counted by the counting component, and the counting is stored by the storage component.

[0019] The silo has a back plate 21 and two side plates 22, which are fixed in a V-shape on the back plate and form a material drop opening at the bottom. A plurality of material tapping shafts 23 are arranged side by side at the material drop opening. The material tapping shaft is controlled by a driving assembly installed on the other side of the mounting base. The driving assembly includes a material tapping motor 24 and a synchronous wheel 25 fixed to the end of the material tapping shaft. A synchronous belt 26 is passed between the material tapping motor and the synchronous wheel, so that the material tapping motor drives the plurality of material tapping shafts to rotate in the same direction, thereby causing the tube needles stacked above the material tapping shaft to move downward into the counting assembly.

[0020] The counting assembly includes a plurality of counting wheels 31 arranged side by side, and a blocking block 32 arranged between two adjacent counting wheels. The counting wheels are controlled to rotate by a servo motor 33 fixed on the other side of the mounting seat, and each counting wheel corresponds to a servo motor. A plurality of arc grooves 34 for accommodating tube needles are evenly spaced on the circumference of the side wall of the counting wheel. The tube needles falling from the material-discharging shaft enter the arc grooves of the counting wheel one by one, and as the counting wheel rotates, the tube needles rotate synchronously and shift and fall into the material storage assembly below. Both side walls of the blocking block are arc structures that fit the counting wheel to avoid displacement of the tube needles during synchronous rotation and ensure that they fall from below.

[0021] The storage assembly includes a fixed plate 41, two groups of lifting cylinders 42, a storage hopper 43, a gate cylinder 44, and a sliding assembly 45. The two sides of the fixed plate are fixed to the mounting seat by lifting cylinders. The area below the counting wheel of the fixed plate is an opening structure for placing the storage hopper. The storage hopper is a plurality of groups, each corresponding to a plurality of counting wheels, and is used to load the tube needles dropped by the counting wheels. The storage hopper has two symmetrically arranged baffle plates 46, one of which is fixed and connected to the fixed plate, and the other is movable and connected to the sliding assembly installed on the surface of the fixed plate. The gate cylinder at the end controls the lateral movement, thereby driving the movable baffle plate to move synchronously horizontally, and realizing the approach and separation between the movable baffle plate and the fixed baffle plate. When storing materials, the baffle plates on both sides approach each other to form a storage cavity. After the tube needles are counted to the specified number, the baffle plates on both sides open the bottom to form a drop opening, so that the tube needles fall downward. When dropping materials, the lifting cylinder controls the fixed plate to descend to approach the loading component (container or packaging bag) below.

[0022] There are multiple groups of storage hoppers in the storage assembly, which correspond to multiple counting wheels one by one, so that one counting wheel corresponds to one storage hopper. Since the counting wheel has a counting function, the number of tube needles in each storage hopper can be accurately known. When the required number is reached, the storage hopper can be opened, and a packaging bag can be set underneath to realize automatic bagging. This structure has accurate counting and automatic control, which eliminates the tedious manual operation and improves the overall efficiency.

[0023] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
