Description

Technical Field

[0001] The present invention relates to the technical field of plastic inspection bag processing equipment, and particularly relates to a heat-sealing processing device and method for inspection bags. Background Art

[0002] An inspection bag is a bag used to store inspection-related items, samples, etc., and is very common in the medical field. The inspection bag (as shown in the attachment) is usually made of plastic, and a self-sealing strip 1' is provided at the opening of the inspection bag. By pinching both sides of the self-sealing strip 1' with fingers, the sealing strip will be tightly pressed together to form a sealed environment, preventing the inspection samples in the bag from leaking or being contaminated by the outside. Figure 7 As shown, it is usually made of plastic and a self-sealing strip 1' is provided at the opening of the inspection bag. By pinching both sides of the self-sealing strip 1' with fingers, the sealing strip will be tightly pressed together to form a sealed environment, preventing the inspection samples in the bag from leaking or being contaminated by the outside.

[0003] In existing production equipment, the self-sealing strip is usually formed by setting a group of heat-sealing blocks with a fixed gap, and a partition block is provided in the middle of the hot pressing strip. The partition block separates the film materials on both sides. After the film materials and the self-sealing strip 1' are well attached, they pass through the gap between the heat-sealing block and the partition block for heat-sealing and attachment. However, this solution has some deficiencies. When the self-sealing strip 1' and the film materials are heat-sealed while feeding, they are prone to shift, resulting in poor heat-sealing effects, such as non-straight heat-sealing lines and low structural strength of the heat-sealing. Summary of the Invention

[0004] The present invention provides a heat-sealing processing device and control method for inspection bags, which can effectively solve the above problems.

[0005] The present invention is implemented as follows:

[0006] A heat-sealing processing device for inspection bags, comprising:

[0007] A main frame;

[0008] A feeding component, arranged at the front end of the main frame, for uncoiling and feeding the material roll;

[0009] A heat-sealing component, arranged on the main frame. The heat-sealing component includes two groups of first heat-sealing assemblies and one group of second heat-sealing assemblies. The first heat-sealing assembly includes two symmetrically arranged first heat-sealing blocks and two partition plates arranged with a gap to form a material guiding groove. The partition plates are arranged between the first heat-sealing blocks in a group of two. The second heat-sealing assembly includes two symmetrically arranged second heat-sealing blocks. The first heat-sealing blocks and the second heat-sealing blocks respectively achieve reciprocating pressing motions through driving components. The length D1 of the first heat-sealing blocks and the length D2 of the second heat-sealing blocks are greater than the width D0 of a single inspection bag, and the length D3 of the partition plates is greater than D1 and D2;

[0011] A material dragging and cutting component is provided on the main frame and on the discharging side of the heat sealing component, which drags the film material to feed a distance equal to the width of one inspection bag at a time and separates a single complete inspection bag from the continuous film material.

[0012] A control component is provided on the main frame.

[0013] As a further improvement, the heat sealing component includes a sub-frame, and the first heat sealing assembly and the second heat sealing assembly are adjustably installed on the sub-frame.

[0014] The driving component includes two rotating shafts driven by a first motor, six cams provided on the rotating shafts, six seat plates with adjustable positions provided on the sub-frame, transmission rods provided on each seat plate and cooperating with the cams, and movable plates provided at the ends of the transmission rods away from the cams. The movable plates are elastically connected to both the first heat sealing block and the second heat sealing block respectively. An elastic element is also provided between the seat plate and the movable plate. By rotating the rotating shaft to drive the cam to rotate and cooperate with the elastic element, the transmission rod drives the heat sealing block to reciprocate.

[0015] As a further improvement, brackets with adjustable positions are provided on both sides of the main frame. The brackets are provided with first adjustment slots, and are fixed to the main frame by bolts passing through the first adjustment slots.

[0016] A perforation along the feeding direction is provided on the bracket. The partition plates are inserted on both sides of the perforation. For the two partition plates in a group, the end face of one partition plate is flush with the bracket, and the other partition plate protrudes.

[0017] As a further improvement, the heat sealing component further includes a first support roller and a second support roller, which are respectively provided at the front and rear ends of the sub-frame and below the partition plates.

[0018] As a further improvement, the heat sealing component further includes two tension springs. The tension springs are fixed on the main frame. One of the tension springs is arranged above the bracket and near the front end position, and the other tension spring is arranged above the partition plate and in the same vertical plane as the first support roller.

[0019] As a further improvement, it further includes a hot pressing and punching component. The hot pressing and punching component includes an annular heat sealing assembly, a punching assembly and a cutting assembly sequentially arranged on the main frame along the moving direction of the film material. The annular heat sealing assembly, the punching assembly and the cutting assembly all include adjustment bases with adjustable positions provided on the main frame, and a second adjustment slot is provided on the adjustment base.

[0020] The annular heat-sealing assembly includes a first base adjustably fixed on the second adjustment groove, and a ring-shaped hot pressing head driven by a cylinder to move up and down is arranged on the first base;

[0021] The punching assembly includes a second base adjustably fixed on the second adjustment groove, a punch driven by a cylinder to move up and down is arranged on the second base, and a punching hole cooperating with the punch is arranged on the second base;

[0022] The cutting assembly includes a third base adjustably fixed on the second adjustment groove, and a blade driven by a cylinder to move up and down is arranged on the third base.

[0023] As a further improvement, it further includes a spraying assembly, which is erected on the main frame behind the heat-sealing component and is used for spraying marks on the surface of the bag body.

[0024] As a further improvement, the material dragging and cutting component includes a first material dragging roller and a second material dragging roller arranged up and down, and further includes a cutter assembly, and the second material dragging roller is driven to rotate by a second motor.

[0025] As a further improvement, an adjustment gear is arranged on the adjustment base, the adjustment gear cooperates with a rack arranged on the main frame to adjust the position of the adjustment base, and a fixing handle is arranged on the adjustment base for fixing the position of the adjustment base.

[0026] As a further improvement, a control method for a heat-sealing processing device for inspection bags includes the following steps:

[0027] S1. Materials pass through each component in sequence;

[0028] S2. The control component controls the material dragging and cutting component to drag the material to feed;

[0029] S3. When the positioning and recognition component recognizes that the material has fed one unit length, it transmits a signal to the control component;

[0030] S4. After receiving the signal, the control component controls the material dragging and cutting component to stop dragging and perform a cutting operation, separates a single complete inspection bag from the continuous material, and simultaneously controls the heat-sealing component and the hot pressing and punching component to perform a single operation;

[0031] S5. Then the control component continues to control the material dragging and cutting component to drag the material to feed, and so on.

[0032] The beneficial effects of the present invention are:

[0033] 1. The material dragging and cutting component drags the film material forward by a distance equal to the width of one inspection bag each time, pauses, and then performs heat sealing through the heat sealing component. This avoids the offset of the self-sealing strip and the film material during heat sealing while feeding, thus ensuring that the heat sealing line is straight and improving the structural strength and overall quality of the heat sealing.

[0034] 2. The lengths of the first heat sealing block and the second heat sealing block are greater than the width of a single inspection bag. In this way, during the heat sealing process, the heat sealing positions of the inspection bag can be heat sealed repeatedly. Repeated heat sealing can avoid the need to use a relatively high temperature for processing during single heat sealing. If the temperature is too high and not properly controlled, it is easy to damage the film material. Repeated heat sealing can better control the temperature and further improve the reliability of the heat sealing. Or when producing inspection bags with similar sizes, it can enhance the flexibility and adaptability of production and save part costs.

[0035] 3. The partition gap in the first heat sealing component is set to form a material guiding groove. When the film material and the self-sealing strip are fed, the material guiding groove can play a role in guiding and limiting, allowing the film material and the self-sealing strip to move along a predetermined path during the heat sealing process, effectively avoiding the offset problem during the heat sealing process.

[0036] 4. The length of the partition is greater than that of the first heat sealing block and the second heat sealing block. This can provide a more sufficient guiding and separating effect for the film material and the self-sealing strip, ensuring that the film materials on both sides always remain separated during the entire heat sealing process, avoiding mutual interference, and further improving the heat sealing quality.

[0055] To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed present invention, but merely represents selected embodiments of the present invention.

[0056] In the description of the present invention, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "a plurality" means two or more, unless otherwise specifically defined.

[0057] Referring to Figure 1-7 as shown, a heat-sealing processing device for inspection bags includes:

[0058] a main frame 1;

[0059] a loading component 2, provided at the front end of the main frame 1, composed of a material roll rack and multiple guide rollers. The loading component 2 unwinds the upper film roll and the lower film roll of the inspection bag, and makes them overlap, move in parallel synchronously, and perform loading; there are two support blocks 21 on the loading component 2 to spread the edges of the stacked upper and lower films, facilitating the insertion of the self-sealing strip between the upper and lower films;

[0060] a heat-sealing component 3, provided on the main frame 1. The heat-sealing component 3 includes two groups of first heat-sealing assemblies 31 and one group of second heat-sealing assemblies 32. The first heat-sealing assembly 31 includes two symmetrically arranged first heat-sealing blocks 311 and two partitions 312 arranged with a gap to form a guide groove 313. The partition 312 is arranged between the two first heat-sealing blocks 311 in a group. The clamping strip portion on the self-sealing strip feeds along the guide groove 313, and the thin films on both sides of the self-sealing strip are respectively located on both sides of the partition 312. The second heat-sealing assembly 32 includes two symmetrically arranged second heat-sealing blocks. The first heat-sealing blocks 311 and the second heat-sealing blocks both perform reciprocating pressing motions through driving components 33. The two groups of first heat-sealing assemblies 31 are arranged on both sides of the second heat-sealing assembly 32, corresponding to two continuous inspection bags processed in parallel on both sides. The first heat-sealing assembly 31 is used to thermally press the self-sealing strip onto the film material, and the second heat-sealing assembly 32 is used to thermally press and seal to form the bottom edge line of the inspection bag. The length D1 of the first heat-sealing block 311 and the length D2 of the second heat-sealing block are greater than the width D0 of a single inspection bag, and the length D3 of the partition 312 is greater than D1 and D2; further, D1 = D2, and 2D0 ≥ D1 ≥ D0. When feeding the width D0 of a single inspection bag at a time, the film material and the self-sealing strip can be repeatedly thermally pressed, making their connection more reliable. High-temperature paper is wrapped on the contact surfaces of the first heat-sealing blocks 311 and the second heat-sealing blocks with the thin film, which can prevent the hot pressing block from directly contacting the thin film and causing defects on the surface of the thin film.

[0061] a positioning and identifying component 4, provided on the main frame 1, used to detect the feeding length of the film material. In one embodiment, the positioning and identifying component 4 can identify the positioning color blocks on the film material through a sensor, and each individual inspection bag is provided with a positioning color block;

[0062] The material dragging and cutting component 5 is arranged on the main frame 1 and is located on the discharging side of the heat-sealing component 3. It is used to drag the film material to feed and hot-press and cut a single inspection bag from the continuous film material. While hot-pressing and cutting, the heat-sealing of the side edges of the inspection bag is completed at the same time. It drags the film material to feed a distance equal to the width of a single inspection bag each time.

[0063] The control component 6 is arranged on the main frame 1 and controls the electronic components on the heat-sealing processing device. The control component 6 can adopt a microcomputer with programming functions.

[0064] Specifically, to realize the reciprocating pressing movement of the heat-sealing block, the following technical solution can be adopted for the structure of the heat-sealing component 3. The heat-sealing component 3 includes a sub-frame 30, and the first heat-sealing assembly 31 and the second heat-sealing assembly 32 are adjustably installed on the sub-frame 30.

[0065] The driving assembly 33 includes a rotating shaft 331 driven by a first motor, a cam 332 arranged on the rotating shaft 331, a seat plate 333 with an adjustable position arranged on the sub-frame 30, a transmission rod 334 arranged on the seat plate 333 and cooperating with the cam 332, and a movable plate 335 arranged at the end of the transmission rod 334 away from the cam 332. The seat plate 333 can adjust its position on the sub-frame 30 to adapt to inspection bags of different specifications. The movable plate 335 is respectively connected to the first heat-sealing block 311 and the second heat-sealing block through first springs, and two first guide rods are also provided, so that the heat-sealing blocks on both sides are pressed more tightly when pressing, and the pressing force can also be adjusted by replacing springs of different specifications to achieve different heat-sealing effects. A second spring is also arranged between the seat plate 333 and the movable plate 335. The second spring is located on the upper end surface of the seat plate 333. One end of the spring is connected to a pull rod, and the pull rod passes through the seat plate 333 and is connected to the movable plate 335. By rotating the rotating shaft 331 to drive the cam 332 to rotate and cooperate with the elastic element 336, the transmission rod 334 drives the heat-sealing block to reciprocate.

[0066] Specifically, to sandwich the self-sealing strip between the upper and lower layers of the film material, the following technical solution can be adopted. Adjustable brackets 34 are arranged on both sides of the main frame 1. The brackets 34 are provided with first adjustment slots 342, and are fixed to the main frame 1 by bolts passing through the first adjustment slots 342, which can be applicable to inspection bags of different specifications and are convenient for adjustment.

[0067] The brackets 34 are provided with a perforation 341 along the feeding direction. The self-sealing strip passes through the perforation 341. Partition plates 312 are inserted on both sides of the perforation 341. The partition plates 312 are in groups of two. One end face of one of them is flush with the bracket 34, and the other partition plate 312 protrudes. The protruding partition plate 312 can play a role in guiding and preventing flipping, preventing the self-sealing strip from twisting and blocking the perforation 341.

[0068] Specifically, the heat-sealing component 3 further includes a first support roller 35 and a second support roller 37, which are respectively arranged at the front and rear ends of the auxiliary frame 30 and below the partition 312, and can support the film material and the self-sealing strip.

[0069] Specifically, the heat-sealing component 3 further includes two tension springs 36. The tension springs 36 are fixed on the main frame 1. One of the tension springs 36 is arranged above the bracket 34 and near the front end position, and the other tension spring 36 is arranged above the partition 312 and in the same vertical plane as the first support roller 35. The upper film material passes under the tension spring 36, and the tension spring 36 plays a pressing role to prevent the upper film material from floating up when entering the heat-sealing block.

[0070] Specifically, it further includes a hot-pressing and punching component 7, which is used to punch holes on the edges of two adjacent inspection bags. After the two inspection bags are separated, a notch is formed on both sides. The hot-pressing and punching component 7 includes an annular heat-sealing assembly 71, a punching assembly 72, and a cutting assembly 73 that are successively arranged on the main frame 1 along the moving direction of the film material. The annular heat-sealing assembly 71, the punching assembly 72, and the cutting assembly 73 all include an adjustable base 700 arranged on the main frame 1, and a second adjustment groove is provided on the adjustable base 700;

[0071] The annular heat-sealing assembly 71 includes a first base 711 that can be adjustably fixed on the second adjustment groove. A ring-shaped hot-pressing head 712 driven by a cylinder to move up and down is provided on the first base 711;

[0072] The punching assembly 72 includes a second base 721 that can be adjustably fixed on the second adjustment groove. A punch driven by a cylinder to move up and down is provided on the second base 721, and a punching hole that cooperates with the punch is provided on the second base 721;

[0073] The cutting assembly 73 includes a third base 731 that can be adjustably fixed on the second adjustment groove. A blade driven by a cylinder to move up and down is provided on the third base 731;

[0074] First, an annular shape is hot-pressed on the film material through the annular heat-sealing assembly 71, and the annular shape is divided into two halves belonging to adjacent inspection bags. Then, a hole is punched in the middle of the annular shape through the punching assembly 72. Finally, a notch is cut at the edge of the punched hole through the cutting assembly 73. When it is necessary to tear the inspection bag horizontally, it is more convenient to tear it through the notch.

[0075] Specifically, it further includes a spraying component 8, which is arranged on the main frame 1 behind the heat-sealing component 3 and is used to spray marks on the surface of the bag body, such as spraying barcodes or two-dimensional codes, etc.

[0076] Specifically, the following technical solution can be adopted for the material dragging and cutting component 5. The material dragging and cutting component 5 includes a first material dragging roller 51 and a second material dragging roller 52 arranged vertically, and also includes a cutter assembly 53. The second material dragging roller 52 is driven to rotate by a second motor 54. The main bodies of the first material dragging roller 51 and the second material dragging roller 52 are both made of rubber material, and the film material passes through the middle for dragging. The cutter assembly 53 is located behind the first material dragging roller 51 and the second material dragging roller 52, and its cutter is preferably driven by a motor, and the up and down movement of the cutter is realized through a reciprocating motion mechanism. As a further improvement, according to the actual capacity of the equipment and the requirements of the heat sealing process, the feeding speed of the material dragging and cutting component 5 can be reasonably adjusted. The feeding speed can be adaptively adjusted according to the equipment load capacity and the heat sealing process parameters. The feeding speed should not be too fast to avoid the film material and the self-sealing strip from shifting due to inertia; at the same time, it should not be too slow to avoid affecting the production efficiency. In other embodiments, a tension sensor (not shown in the figure) can be installed on the production line. The tension sensor is electrically connected to the control component 6 and is used to collect the film material tension data in real time and feedback it to the control system. When the tension fluctuates, the tension sensor transmits the signal to the control system, and the system automatically adjusts the dragging speed according to the tension change. If the tension value is greater than the upper limit threshold (indicating that the film material is tight), the control component sends a deceleration instruction to the second motor 54 of the material dragging and cutting component 5, and reduces the film material tensile stress by reducing the dragging speed to avoid the film material from tearing or the self-sealing strip from shifting due to excessive tension; if the tension value is less than the lower limit threshold (indicating that the film material is loose), the control component 6 sends an acceleration instruction to increase the dragging speed to tighten the film material and prevent the film material from stacking or the conveying from shifting due to insufficient tension. Through the closed-loop feedback adjustment of the tension sensor and the control system, it can ensure that the film material always maintains a stable tension (fluctuation range ≤ ±5N) during the conveying process, suppress the heat sealing offset problem caused by uneven tension from the source, and at the same time balance the production efficiency and the processing accuracy.

[0077] Specifically, to facilitate adapting to inspection bags of different specifications, the following technical solution can be adopted for the adjusting base 700. An adjusting gear is provided on the adjusting base 700, and the adjusting gear cooperates with the rack provided on the main frame 1 to adjust the position of the adjusting base 700. And a fixing handle is provided on the adjusting base 700 for fixing the position of the adjusting base 700.

[0078] A control method for a heat sealing processing device of an inspection bag includes the following steps:

[0079] S1. The material passes through each component in sequence;

[0080] S2. The control component 6 controls the material dragging and cutting component 5 to drag the material for feeding;

[0081] S3. When the positioning and recognition component 4 recognizes that the material has fed one unit length, it transmits a signal to the control component 6;

[0082] After the control component 6 receives the signal, it controls the material dragging and cutting component 5 to stop dragging and perform a cutting operation, separating a single complete inspection bag from the continuous material. At the same time, it controls the heat sealing component 3 and the hot pressing and punching component 7 to perform a single operation;

[0083] S5. Then the control component 6 continues to control the material dragging and cutting component 5 to drag the material for feeding, and so on.

[0084] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
