Description

Technical Field

[0001] The utility model relates to the field of acupuncture needle packaging, and more specifically to a cursor-free positioning printing and fixed-length cutting type acupuncture needle bag packaging and a manufacturing device. Background Art

[0002] Plastic packaging bags have been widely used in acupuncture needle packaging. Before packaging, plastic packaging bags are long strips connected in series. After acupuncture products are placed in them, they need to be heat-sealed and cut into independent packages. In order to ensure that the heat-sealing and cutting operations do not deviate, the packaging machine needs to print a color block (cursor) for positioning on the plastic packaging bag in advance. The packaging machine detects the color block positioning to ensure the accuracy of the heat-sealing and cutting operations. However, this requires a special color block recognition packaging machine. For packaging bags of different lengths, color blocks (cursors) with different spacing distances need to be printed. The printing cost is high, and general packaging machines without color block recognition cannot be used, resulting in a high cost for acupuncture needle packaging. Utility Model Content

[0003] 1. Technical problems to be solved by the utility model

[0004] In view of the problem that the prior art of Chinese medical acupuncture needle packaging contains color block identification, which leads to high packaging costs, the utility model provides a kind of acupuncture needle bag packaging and production device which does not require cursor positioning printing and can be cut to a fixed length. Through the coordinated technical means of fixed-length traction and periodic printing of pattern layers, the cutting length is determined without the need for cursor positioning printing, thereby achieving the purpose of reducing the packaging cost of medical acupuncture needles.

[0005] 2. Technical solution

[0006] In order to achieve the above-mentioned purpose, the technical solution provided by the utility model is:

[0007] A kind of acupuncture needle bag packaging that does not require cursor positioning printing and is cut to a fixed length. A heat sealing mechanism is used to heat-seal and fix a transparent plastic film and a breathable paper to form a series packaging bag, and then a fixed-length packaging bag length is pulled out by a fixed-length pulling mechanism for cutting by a cutting mechanism. The length of the packaging bag is set according to the length of the acupuncture needle, and then the fixed-length packaging bag length is cut by the cutting mechanism to produce the packaging bag; a periodic printed pattern layer is printed on the back of the breathable paper, and there is no need for printed color block recognition. When the periodic printed pattern layer is cut, there is no need for cursor positioning, thereby reducing the packaging cost.

[0008] A further technical solution is that the fixed-length traction mechanism is a symmetrically arranged traction wheel on both sides of the serial packaging bag. The traction length is determined according to the arc and number of turns of the traction wheel. When it reaches a specific length, the traction is stopped and the front and rear workstations are instructed to perform their respective operations. After completion, the traction action is continued. Cylinder clamping can also be used, and then the length is set by moving in the discharge direction.

[0009] A further technical solution is to set scales on the wheel surface of the traction wheel to further accurately control the fixed length.

[0010] A method for making the above-mentioned acupuncture needle bag, the specific steps are:

[0011] S1, the breathable paper and the transparent plastic film are respectively fed from the parallel breathable paper roll and the plastic film roll, and the two form a laminated upper and lower double-layer structure, and are fed to the bottom edge heat sealing mechanism under the traction of the subsequent fixed-length traction mechanism;

[0012] S2, the bottom edge heat-sealing mechanism heat-seals the bottom edge of the double-layer structure to form a heat-sealed edge;

[0013] S3, after the upper side of the double-layer structure is opened by the discharge mechanism, a certain amount of acupuncture needles are placed in the double-layer structure;

[0014] S4. Under the traction of the fixed-length traction mechanism, the heat-sealing mechanism heat-seales the other three sides of the double-layer structure to form a series of acupuncture needle bags;

[0015] S5, the fixed-length packaging bag is drawn out by the fixed-length drawing mechanism for cutting by the cutting mechanism, and then the fixed-length packaging bag is cut into lengths by the cutting mechanism.

[0016] A further production method is that the breathable paper roll and the plastic film roll are guided by guide wheels to improve the adaptability of the working stroke length of both and achieve a tensioned and smooth feeding effect, and are fed to the bottom edge heat sealing mechanism after being compressed by a clamping wheel, which facilitates subsequent heat sealing and plastic sealing processing.

[0017] A further manufacturing method is that a steering block is provided between the clamping wheel and the bottom edge heat sealing mechanism to turn the horizontal double-layer structure to a vertical direction, so as to facilitate the subsequent discharge mechanism to discharge the acupuncture needles by their own weight.

[0018] 3. Beneficial effects

[0019] Compared with the prior art, the technical solution provided by the utility model has the following beneficial effects:

[0020] (1) The present invention is a device for packaging and making acupuncture needle bags without cursor positioning printing and fixed-length cutting. The existing printing machine is used to print periodically repeated patterns and texts on the back of breathable paper. The packaging machine does not need to consider the deviation of the pattern cutting position. The pattern is complete at any cutting position. In this way, there is no need to print cursor color blocks. The heat sealing and cutting actions of the packaging machine can be controlled by the fixed-length feeding of the packaging bag feeding mechanism. After each fixed-length feeding step, heat sealing, loading, cutting and other operations are performed, and then fixed-length feeding is performed again, and the cycle is repeated.

[0021] (2) The cursor-free positioning printing and fixed-length cutting acupuncture needle bag packaging and production device of the utility model can use a traditional printing machine to print periodically repeated patterns and texts, such as manufacturer, contact number, specifications, instructions for use and other text information, without the need for color block printing, cheap ink, low price of printing equipment, no need to consider different printing layouts for different lengths, no need to change printing plates for different specifications, and low printing costs;

[0022] (3) Compared with the existing method, which requires cursor positioning to ensure that the position will not deviate, if cursor positioning is not used and fixed-length feeding is adopted, the pattern will deviate more and more due to the accumulated deviation. The present invention is a cursor positioning-free printing and fixed-length cutting acupuncture needle bag packaging and production device. The packaging machine cancels the cursor color block detection device and changes to fixed-length feeding. The actions of other workstations are synchronized with the feeding mechanism. The printed pattern is repeated periodically, without a starting position and an ending position, and there is no need to consider pattern positioning. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] In order to further understand the content of the utility model, the utility model is described in detail with reference to the accompanying drawings.

[0028] Example 1

[0029] In the present embodiment of the cursor-free positioning printing and fixed-length cutting type acupuncture needle bag packaging, a heat-sealing mechanism 6 heat-seals and fixes a transparent plastic film 12 and a breathable paper 11 to form a series packaging bag. The heat-sealing mechanism 6 can use an existing heating plastic sealing mold; then the fixed-length packaging bag length for cutting by the cutting mechanism 8 is pulled out by the fixed-length traction mechanism 7. The fixed-length traction mechanism 7 can use symmetrically arranged traction wheels arranged on both sides of the series packaging bag for traction feeding. The traction length is determined according to the arc and number of turns of the traction wheel rotation. After reaching the set length, the traction is stopped, and the front and rear stations are instructed to perform their respective operations. After completion, the traction action is continued; it can also be clamped by a cylinder, and then moved in the discharge direction to set the length; the length of the packaging bag is set according to the length of the acupuncture needle 10, and then the fixed-length packaging bag is cut by the cutting mechanism 8 to produce it; the back of the breathable paper 11 is printed with a periodic printed pattern layer 111, and there is no need for printed color block recognition. The periodic printed pattern of the periodic printed pattern layer 111 does not require cursor positioning when cutting, thereby reducing the packaging cost.

[0030] The specific manufacturing method of the acupuncture needle bag of this embodiment is as follows: Figure 1 The bagging production device shown in the figure is made, and the bagging production device includes a breathable paper roll 1 and a plastic film roll 2 arranged in parallel, and a bottom edge heat sealing mechanism 4, a discharge mechanism 5, a heat sealing mechanism 6, a fixed-length traction wheel and a cutting mechanism 8 arranged in sequence according to the feeding direction; two fixed-length traction wheels are arranged symmetrically on both sides of the packaging bag in series, and the breathable paper 11 and the transparent plastic film 12 of the whole device are fed by the fixed-length traction wheel. The specific production process is:

[0031] S1, the breathable paper roll 1 and the plastic film roll 2 are respectively fed with breathable paper 11 and transparent plastic film 12, and the two form a laminated upper and lower double-layer structure, which is fed to the bottom edge heat sealing mechanism 4 under the traction of the subsequent fixed-length traction mechanism 7;

[0032] S2, the bottom edge heat-sealing mechanism 4 heat-seals the bottom edge of the double-layer structure to form a heat-sealed edge 13;

[0033] S3, after the upper side of the double-layer structure is opened by the discharge mechanism 5, a certain amount of acupuncture needles 10 are placed in the double-layer structure;

[0034] S4, under the traction of the fixed-length traction mechanism 7, the heat-sealing mechanism 6 heat-seals the other three sides of the double-layer structure to form a series packaging bag;

[0035] S5, the fixed-length packaging bag is drawn out by the fixed-length drawing mechanism 7 for cutting by the cutting mechanism 8, and then the fixed-length packaging bag is cut into pieces as shown in FIG. Figure 2 , 3 Acupuncture needles shown in bag.

[0036] like Figure 2 , 3As shown, the acupuncture needle bag of this embodiment includes a heat-sealed edge 13 formed around the packaging bag after a breathable paper 11 and a transparent plastic film 12 are pressed and fixedly connected by a heated mold, and a packaging area for accommodating parallel acupuncture needles 10 is formed in the middle of the packaging bag, and a periodic printed pattern layer 111 is printed on the back of the bagged breathable paper 11.

[0037] Compared with the existing method, cursor positioning is required to ensure that the position will not deviate. If cursor positioning is not used and fixed-length feeding is adopted, the pattern will deviate more and more due to the accumulated deviation. The cursor positioning-free printing and fixed-length cutting acupuncture needle bagging and production device of this embodiment, the bagging production device cancels the cursor color block detection device and changes to fixed-length feeding, and the actions of other stations are synchronized with the feeding mechanism; the pattern of the periodically printed pattern layer 111 is repeated periodically, without a starting position and an ending position, and there is no need to consider pattern positioning.

[0038] Example 2

[0039] The cursor-free positioning printing and fixed-length cutting acupuncture needle bagging and manufacturing device of this embodiment has the same basic structure and steps as the first embodiment, and the difference or improvement is that: the wheel surface of the fixed-length traction wheel is provided with a scale, and when the fixed length is not a full circle, the fixed length can be precisely controlled; in order to further improve the fixed length accuracy, the traction wheel is preferably driven by a stepper or servo motor, and an encoder can also be added to detect the fixed length size, so that the fixed length accuracy is higher. Figure 1 As shown, the air-permeable paper roll 1 and the plastic film roll 2 are guided by two or more guide wheels 9 below them respectively, so as to improve the adaptability of the working stroke length of the two and achieve the tension-type flat feeding effect, and are pressed by the clamping wheel 91 to feed the bottom edge heat sealing mechanism 4, so as to facilitate the subsequent heat sealing and plastic sealing process. A steering block 3 is also arranged between the clamping wheel 91 and the bottom edge heat sealing mechanism 4. The steering block 3 penetrates the vertical perforation for the double-layer structure bag to pass through, and turns the horizontal double-layer structure from horizontal to vertical, so as to facilitate the subsequent discharge mechanism 5 to drop the acupuncture needle 10 into the double-layer structure bag with its own weight. The discharge mechanism 5 can adopt a discharge wheel, and a needle groove is reserved in the circumference of the wheel in the horizontal direction. The diameter of the needle groove is slightly larger than the acupuncture needle 10 for taking the acupuncture needle 10. After taking the material, when it rotates to the upper opening of the double-layer structure bag, it automatically falls into the opening due to its own weight from the groove to complete the discharge process.

[0040] The cursor-free positioning printing and fixed-length cutting acupuncture needle bagging and production device of this embodiment can use the existing printing machine to print periodically repeated patterns and texts on the back of the breathable paper. The bagging production device does not need to consider the deviation of the pattern cutting position. The pattern is complete when cut at any position, and there is no need to print the cursor color block; the heat sealing and cutting and other actions of the bagging production device can be controlled by the fixed-length feeding of the packaging bag feeding mechanism. After each fixed-length feeding, heat sealing, loading, cutting and other operations are performed, and then fixed-length feeding is performed again, and the cycle is repeated; the repeated pattern texts in the pattern layer 111, such as the manufacturer, contact number, specifications, usage and other text information, are periodically printed without color block printing, the ink is relatively cheaper, and the corresponding printing equipment price is also low. There is no need to consider using different printing layouts for different lengths, and there is no need to change the printing plate for different specifications. Moreover, the unified printing plate greatly reduces the management cost, and there is no need to classify and manage different printing layouts. According to calculations, the production cost of the acupuncture needle bagging of this embodiment is only about 30% of that of the existing packaging machine.

[0041] Example 3

[0042] The cursor-free positioning printing and fixed-length cutting acupuncture needle bagging and manufacturing device of this embodiment have the same basic structure and steps as Example 2, and the difference or improvement is that: the acupuncture needle bagging also includes a foam hot pressing fixing area 121 for hot pressing and fixing the parts of the parallel acupuncture needles 10 in parallel; the parts of the acupuncture needles 10 are fixed in the packaging bag by the foam hot pressing fixing area 121, and the parts of the acupuncture needles 10 can be the head of the acupuncture needle 10, or the handle thereof, or both the head and the handle; after the parts are fixed, the technical effect of preventing the acupuncture needles 10 from moving vertically and piercing the packaging bag is achieved. In step S4 of the specific manufacturing process, a layer of foam is placed in the heating mold of the heat-sealing mechanism 6 in the area where the needle tip and / or the needle handle of the acupuncture needle 10 are located, that is, one or both of the needle tip and the needle handle are selected to prevent the heating mold from being in too hard contact with the breathable paper 11 and the transparent plastic film 12. While playing a buffering role, the foam also has the characteristic of rapid pressure-sensitive fixing. The breathable paper 11 and the transparent plastic film 12 are pressed against the heating mold, so that the mold heats the area and the breathable paper 11 and the transparent plastic film 12 are sealed together. Figure 2 As shown, for example, a sandwich-fixed foam hot-pressed fixing area 121 is formed at the needle tip of the acupuncture needle 10 to achieve the technical effect of preventing the acupuncture needle 1 from moving vertically and piercing the acupuncture needle bag.

[0043] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure and manufacturing steps are not limited thereto. Therefore, if a person skilled in the art is inspired by it and, without departing from the purpose of the invention, designs a structure and an implementation method similar to the technical solution without creativity, they should all fall within the protection scope of the present invention.
