Description

Technical Field

[0001] The utility model relates to the technical field of paper-plastic bag detection, in particular to a detection device for the thermally welded processing finished products of medical paper-plastic bags. Background Technique

[0002] The paper-plastic bag, also known as the three-in-one composite paper bag, is composed of plastic and kraft paper. Usually, the plastic layer is a pp flat wire woven cloth with polypropylene as the base material, and the kraft paper is a refined composite special kraft paper. The two are bonded by molten plastic heat lamination. The kraft paper laminated cloth is formed into a bag through bag making, and then processed and sewn into a three-in-one paper-plastic bag.

[0003] In the field of medical devices, many devices are packaged in disposable paper-plastic bags. Due to the strict storage requirements of medical equipment, the production of paper-plastic bags also needs to be carried out in a dust-free environment. The paper-plastic bags are formed through thermal welding processing. Before a large number of products leave the factory, it is necessary to measure the qualification rate of the paper-plastic bags. Among them, the tightness of the sealing edge is an important indicator, and it will also affect the storage quality of the equipment inside the package. Therefore, a detection device for the thermally welded processing finished products is required for detection. The existing detection methods mainly rely on workers to open the paper-plastic bags and observe, and it is impossible to directly judge whether they meet the factory requirements. Content of the Utility Model

[0004] The utility model aims at the defects in the prior art and provides a detection device for the thermally welded processing finished products of medical paper-plastic bags.

[0005] The utility model is realized through the following technical solutions:

[0006] A detection device for the thermally welded processing finished products of medical paper-plastic bags includes a housing assembly and a fixing device. The fixing device is clamped inside one end of the housing assembly. The housing assembly includes a bottom plate, a protective cover and a wind sensing device. The protective cover is fixedly arranged at the top of one end of the housing assembly, and the wind sensing device is arranged inside the protective cover. The fixing device includes a sliding plate, a support frame, a cylinder, a connecting strip, a collar, a sleeve column, an air inlet pipe, a support rod and a fan. The support frame is fixed on the top of the sliding plate. The cylinder is installed at both ends on one side of the support frame. The connecting strip is fixedly arranged at the telescopic end of the cylinder. The collar is fixedly arranged at the end of the connecting strip. The sleeve column is fixedly arranged in the middle of the support frame. The air inlet pipe is clamped inside the sleeve column. The air outlet of the fan is connected to one end of the air inlet pipe. The support rod is installed between the fan and the sliding plate.

[0007] In a preferred embodiment of the utility model, the wind sensing device includes a mounting frame, a clamping shaft, a sleeve and a swing piece. The mounting frame is connected to the inner side of the top of the protective cover. The clamping shaft is clamped at the bottom of the mounting frame. The sleeve is sleeved outside the clamping shaft. The swing piece is fixedly arranged at the bottom of the sleeve;

[0008] When the air-sensitive device mainly generates a rupture in the paper-plastic bag, the swing piece in the corresponding area will shake, so as to visually observe the rupture area, and quickly judge whether the edge of the paper-plastic bag is sealed.

[0009] In a preferred embodiment of the present invention, the protective cover is made of transparent acrylic material, and a card slot is opened on the inner side thereof. The sliding plate is clamped in the card slot on the inner bottom of the protective cover, and the bottom of the sliding plate contacts the bottom of the bottom plate.

[0010] The protective cover made of transparent material is convenient for observing the internal swing piece. The sliding plate is movably connected to the protective cover, which is convenient for inserting the clamped paper-plastic bag into the inside of the housing assembly.

[0011] In a preferred embodiment of the present invention, one end of the sleeve column is in a conical structure. The sleeve column and the sleeve ring are concentrically arranged, and an exhaust hole is opened through the sleeve column.

[0012] The exhaust hole mainly discharges the excess gas after the paper-plastic bag expands, so as to avoid the interference of the internal air flow on the air-sensitive device.

[0013] In a preferred embodiment of the present invention, the mounting frame is in a U-shaped structure, and grooves for the cooperation of the sleeve are uniformly opened at the bottom thereof.

[0014] In a preferred embodiment of the present invention, the swing piece is a plastic or aluminum thin sheet, and the width of the bottom thereof is greater than the width of the top.

[0015] The swing piece is a plastic or aluminum thin sheet, and the greater width of the bottom is mainly to improve the sensitivity of the swing piece, so as to facilitate observation.

[0016] The beneficial effects of the present invention are:

[0017] After the paper-plastic bag is effectively clamped, the paper-plastic bag heat-sealing processing finished product detection device of the present invention blows air into the paper-plastic bag to make it expand. The excess gas after expansion is discharged from the exhaust hole, and whether the swing piece shakes due to gas leakage at the edge of the paper-plastic bag is used to visually judge whether the edge sealing of the paper-plastic bag is reliable, so as to effectively judge the heat-sealing quality of the paper-plastic bag and estimate the qualified rate of the paper-plastic bag.

[0024] The following elaborates on the preferred embodiments of the present utility model in conjunction with the accompanying drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present utility model. The directional terms mentioned in the present utility model, such as "up", "down", "front", "rear", "left", "right", "top", "bottom", etc., are only references to the directions of the attached drawings. Therefore, the directional terms used are for explaining and understanding the present utility model, rather than for limiting the present utility model.

[0025] As Figures 1-5 shown, a finished product detection device for heat-sealing medical paper-plastic bags includes a housing assembly 1 and a fixing device 2. The fixing device 2 is clamped inside one end of the housing assembly 1. The housing assembly 1 includes a bottom plate 11, a protective cover 12 and an air-sensing device 13. The protective cover 12 is fixedly arranged on the top of one end of the housing assembly 1. The air-sensing device 13 is arranged inside the protective cover 12. The fixing device 2 includes a slide plate 21, a support frame 22, a cylinder 23, a connecting bar 24, a collar 25, a sleeve column 26, an air inlet pipe 27, a support rod 28 and a fan 29. The support frame 22 is fixed on the top of the slide plate 21. The cylinder 23 is installed at both ends of one side of the support frame 22. The connecting bar 24 is fixedly arranged at the telescopic end of the cylinder 23. The collar 25 is fixedly arranged at the end of the connecting bar 24. The sleeve column 26 is fixedly arranged in the middle of the support frame 22. The air inlet pipe 27 is clamped inside the sleeve column 26. The air outlet of the fan 29 is connected to one end of the air inlet pipe 27. The support rod 28 is installed between the fan 29 and the slide plate 21.

[0026] Specifically, the wind sensing device 13 includes a mounting frame 131, a clamping shaft 132, a sleeve 133 and a swinging piece 134. The mounting frame 131 is connected to the inner side of the top of the protective cover 12, the clamping shaft 132 is clamped at the bottom of the mounting frame 131, the sleeve 133 is sleeved on the outside of the clamping shaft 132, and the swinging piece 134 is fixedly set at the bottom of the sleeve 133. The protective cover 12 is made of transparent acrylic material, and a clamping groove is opened on the inner side thereof. The slide plate 21 is clamped in the inner clamping groove at the bottom of the protective cover 12, and the bottom of the slide plate 21 contacts the bottom of the base plate 11. One end of the sleeve column 26 is a conical structure, and the sleeve column 26 and the sleeve ring 25 are concentrically arranged. An exhaust hole is opened in the sleeve column 26. The mounting frame 131 is a U-shaped structure, and grooves are evenly opened at the bottom thereof for easy matching of the sleeve 133. The swinging piece 134 is a plastic or aluminum sheet, and its bottom width is greater than the top width.

[0027] In this embodiment, the slide plate 21 is first pulled out from the protective cover 12, the paper-plastic bag is installed, and the open end of the paper-plastic bag is sleeved on the conical end of the sleeve column 26 so that its opening contacts the surface of the conical end of the sleeve column 26, and ensures that the open end of the paper-plastic bag is sleeved outside the exhaust hole of the conical end, and then the cylinder 23 is driven to contract. Under the action of the connecting strip 24, the sleeve ring 25 is sleeved outside the conical end of the sleeve column 26 to clamp and fix the open end of the paper-plastic bag, and then the slide plate 21 is pushed until the paper-plastic bag enters the protective cover 12.

[0028] Furthermore, the fan 29 is turned on, and air enters from the side air inlet and is input into the air inlet pipe 27 through the air outlet. A large amount of air rushes in to prop up the inside of the paper-plastic bag and bear a certain air pressure. The excess air is discharged from the exhaust hole. If the paper-plastic bag cannot bear a certain air pressure or there is an unbonded area on its edge, the air will leak out and blow on the surface of the external swinging piece 134, causing the swinging piece 134 to shake on the surface of the clamping shaft 132 through the sleeve 133, so as to determine whether there is a leak point. The protective cover 12 is made of acrylic material. The transparent acrylic material not only facilitates the observation of the state of the swinging piece 134, but also prevents the internal swinging piece 134 from being affected by the external airflow. The support rod 28 set between the fan 29 and the slide plate 21 reduces the shaking of the fan 29 during operation and improves the operation stability.

[0029] It should be noted that the parts not covered in the present invention are the same as the prior art or can be implemented by the prior art; the various drives in the present invention can be implemented by corresponding power structures such as cylinders, oil cylinders, electric cylinders, motors, etc. in combination with connecting rods, guide rods, etc., and are not limited to the description in the specification and the structures in the drawings.
