Description

Technical Field

[0001] The utility model relates to the technical field of composite packaging bag sealing strength detection tools, in particular to a convenient tool for sealing inspection of food and medicine composite packaging bags. Background Art

[0002] Composite packaging bags are made of multiple layers of materials. These bags are usually made of different material layers (such as plastic, paper, aluminum foil, etc.) bonded together through certain processes (such as extrusion lamination, heat sealing, etc.). They are usually used to package food and medicine. When composite packaging bags are produced and used to pack medicines in pharmacies, in order to avoid leakage, sealing strength testing tools are usually required to test the sealing degree of the packaging bags before loading the medicines.

[0003] The existing patent (publication number: CN211281737U) "The utility model discloses a convenient tool for sealing inspection of composite packaging bags for food and medicine, which relates to the field of sealing inspection tools for composite packaging bags. It solves the technical problems of low efficiency, inconvenient detection and incomplete detection of the sealing strength of composite packaging bags in the prior art. It includes a main body, which includes a fixed bracket and a plurality of detection brackets, and all the detection brackets are fixed on the fixed bracket at intervals. The convenient tool for sealing inspection of composite packaging bags for food and medicine disclosed in this utility model can efficiently, quickly and comprehensively detect the sealing strength of composite packaging bags, thereby improving production efficiency and product quality."

[0004] When in use, a pushing force is applied to the bottom of the packaging bag through the detection bracket at the upper end of the fixed bracket, but the detection bracket is fixedly arranged at the upper end of the fixed bracket, and the number of the detection brackets cannot be changed according to the size of the bottom of the packaging bag. The practicality is relatively low, and when performing the detection, the poking force is usually applied manually. When used for the first time, it is difficult to control the size of the poking force, which is relatively troublesome.

[0005] Therefore, those skilled in the art provide a convenient tool for sealing inspection of food and drug composite packaging bags to solve the problems raised in the above background technology. Utility Model Content

[0006] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a convenient tool for sealing inspection of food and medicine composite packaging bags. By setting a pressure spring, a writing pen and a writing board, it is possible to better control the top force applied to the sealing part of the packaging bag. By setting three pressure springs with different elastic forces, the top force can be changed according to the specifications of the packaging bag, thereby improving practicality.

[0007] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a convenient tool for sealing and inspecting composite packaging bags for food and medicine, comprising a fixing mechanism and an inspection mechanism, wherein the fixing mechanism comprises an L-shaped plate, a screw, an extrusion plate, a sliding hole, a hand-pull plate, three sliding grooves, three discs, a fixing plate, and a writing board, a return spring being fixedly provided between the hand-pull plate and the sliding hole, and a pressure spring being fixedly provided between the lower end surfaces of the three discs and the inner bottom surfaces of the three sliding grooves;

[0008] The inspection mechanism includes a mouth-shaped plate, a writing pen, multiple placement grooves and multiple top blocks. A support plate is fixedly provided at the middle position of the upper end surface of the mouth-shaped plate, a placement plate is fixedly provided on the upper end surface of the support plate, cylinders are fixedly provided on the inner bottom surfaces of multiple placement grooves, and rubber sleeves are fixedly provided on the outer end surfaces of multiple cylinders.

[0009] Furthermore, the screw rod is rotatably arranged in the middle position of the front side of the lower end face of the L-shaped plate, and the inner wall of the front side of the extrusion plate is threadedly sleeved on the lower side of the outer end face of the screw rod.

[0010] Furthermore, the sliding hole is opened in the middle position of the upper end surface of the L-shaped plate, and the hand-pull plate is slidably arranged between the front and rear inner walls of the sliding hole.

[0011] Furthermore, the three sliding grooves are all opened on the inner bottom surface of the L-shaped plate, and the three discs are respectively slidably mounted on the upper sides of the three sliding grooves.

[0012] Furthermore, the fixing plate is fixedly arranged on the upper side of the rear end surface of the L-shaped plate, and the writing board is fixedly arranged inside the fixing plate by bolts.

[0013] Furthermore, the mouth-shaped plate is slidably connected to the L-shaped plate, and the writing pen is fixed inside the support plate by bolts.

[0014] Furthermore, the plurality of placement grooves are all provided on the upper end surface of the placement plate, and the lower sides of the outer end surfaces of the plurality of top blocks are respectively slidably sleeved inside the plurality of placement grooves.

[0015] The utility model has the following beneficial effects:

[0016] 1. The utility model proposes a convenient tool for sealing inspection of food and medicine composite packaging bags. By rotating the screw rod to drive the extrusion plate to move upward, the device is fixed to the edge of the table, so that when inspecting, it is only necessary to hold the bottom of the packaging bag and move it downward, which is more convenient. By providing multiple placement slots on the end face of the placement plate, it is possible to install a suitable number of top blocks on the surface of the placement plate according to the size of the bottom of the packaging bag, thereby improving the practicality of the device.

[0017] 2. The utility model proposes a convenient tool for sealing inspection of composite packaging bags of food and medicine. By setting three pressure springs with different elastic forces, before conducting the inspection, the appropriate pressure spring is selected according to the specifications of the packaging bag. By pulling the hand-pull plate to one side while moving the mouth-shaped plate, when it moves to the upper end of the appropriate disc, the pull of the hand-pull plate is released, thereby further improving the practicality of the device. In addition, when conducting the inspection, a preliminary inspection can be carried out first. When the top block breaks the packaging bag, the relative position between the bottom of the line drawn by the writing pen and the scale line of the writing board is observed. When it is found that multiple packaging bags are broken at this position, the next time the inspection is conducted, it is only necessary to ensure that the downward pressure position does not exceed the scale line, which is more convenient.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Reference Figure 1 、 Figure 2 , the utility model provides an embodiment: a convenient tool for sealing inspection of food and drug composite packaging bags, including a fixing mechanism 1 and an inspection mechanism 2, the fixing mechanism 1 includes an L-shaped plate 101, a screw rod 102, an extrusion plate 103, a sliding hole 104, a hand-pull plate 105, three sliding grooves 107, three discs 108, a fixing plate 110 and a writing board 111, the screw rod 102 is rotatably arranged in the middle position of the front side of the lower end face of the L-shaped plate 101, the front inner wall of the extrusion plate 103 is threadedly sleeved on the lower side of the outer end face of the screw rod 102, and the writing pen 203 is fixed inside the support plate 202 by bolts, and the inspection mechanism 2 includes a mouth-shaped plate 201, a writing pen 203, multiple placement slots 205 and multiple top blocks 208.

[0028] Specifically, by rotating the screw rod 102, the screw rod 102 drives the extrusion plate 103 to move upward, so that the extrusion plate 103 is against the bottom of the desktop, and the device can be fixed to the desktop. After adjusting the position of the mouth-shaped plate 201 and selecting the appropriate number of driving top blocks 208, the writing pen 203 is placed inside the support plate 202. When the tip of the writing pen 203 is against the end face of the writing board 111, the bolt on the end face of the support plate 202 is rotated to connect the writing pen 203 to the support plate 202. After the preparations are done, manually hold the bottom of the packaging bag at the upper end of multiple top blocks 208. At this time, hold the bottom and move it downward. The bottom drives multiple top blocks 208 to move downward. Through the rebound force of the pressure spring 109, a top force can be applied to the bottom of the packaging bag, thereby testing the sealing degree of the bottom of the packaging bag.

[0029] refer to Figure 3 、 Figure 4 A return spring 106 is fixedly arranged between the hand-pull plate 105 and the sliding hole 104. The sliding hole 104 is opened in the middle position of the upper end surface of the L-shaped plate 101. The hand-pull plate 105 is slidably arranged between the front and rear inner walls of the sliding hole 104. The mouth-shaped plate 201 is slidably connected to the L-shaped plate 101. Pressure springs 109 are respectively fixedly arranged between the lower end surfaces of the three disks 108 and the inner bottom surfaces of the three sliding grooves 107. The three sliding grooves 107 are all opened in the inner bottom surface of the L-shaped plate 101, and the three disks 108 are respectively slidably sleeved on the upper side of the three sliding grooves 107.

[0030] Specifically, by setting pressure springs 109 with small to large elastic forces at the bottom of the three sliding grooves 107, here we take the relatively small force that the packaging bag needs to withstand as an example, by pulling the hand-pull plate 105 to one side while holding the mouth-shaped plate 201 and moving it forward, when it can no longer move, release the pull on the hand-pull plate 105. At this time, under the action of the reset spring 106, the protrusion measured on the front surface of the hand-pull plate 105 enters the interior of the mouth-shaped plate 201, thereby fixing the mouth-shaped plate 201 so that the mouth-shaped plate 201 can only move in the vertical direction. At this time, the lower end of the mouth-shaped plate 201 is fitted together with the front disc 108. When the mouth-shaped plate 201 moves downward, the mouth-shaped plate 201 drives the disc 108 to move downward. At this time, the rebound force of the pressure spring 109 can apply an upward push to the mouth-shaped plate 201.

[0031] refer to Figure 1 、 Figure 5 、 Figure 6 A support plate 202 is fixedly provided in the middle position of the upper end surface of the mouth-shaped plate 201, and a placement plate 204 is fixedly provided on the upper end surface of the support plate 202. Cylinders 206 are fixedly provided on the inner bottom surfaces of multiple placement grooves 205, and rubber sleeves 207 are fixedly provided on the outer end surfaces of multiple cylinders 206. The fixing plate 110 is fixedly provided on the upper side of the rear end surface of the L-shaped plate 101, and the writing board 111 is fixedly provided inside the fixing plate 110 by bolts. Multiple placement grooves 205 are all opened on the upper end surface of the placement plate 204, and the lower sides of the outer end surfaces of multiple top blocks 208 are respectively slidably sleeved inside the multiple placement grooves 205.

[0032] Specifically, after the position of the mouth-shaped plate 201 is adjusted, the appropriate top block 208 can be selected according to the size of the bottom of the packaging bag. When there are more top blocks 208, the top blocks 208 on both sides of the surface of the placement plate 204 can be pulled upward. When there are fewer top blocks 208, new top blocks 208 can be inserted downward on both sides of the surface of the placement plate 204. When the top blocks 208 are inserted, the cylinder 206 drives the rubber sleeve 207 on its surface to enter the lower side of the top block 208. The friction force of the rubber sleeve 207 can fix the top block 208 in the placement groove 205. When using it for the first time, it is not clear where the mouth-shaped plate 201 should be. When the bottom of the packaging bag is pierced by the top block 208, the relative position between the bottom of the remaining line and the scale line of the writing board 111 is observed. After multiple inspections, it is found that the bottoms of multiple packaging bags are pierced at this position. When squeezing is performed next time, it is only necessary to ensure that the distance moved downward by the writing pen 203 does not exceed this position.

[0033] Working principle: Manually lean the L-shaped plate 101 against the edge of the table, then rotate the screw 102 to fix the device on the edge of the table. When the packaging bag to be inspected is relatively small, pull the hand-pull plate 105 to one side while holding the mouth-shaped plate 201 and move it forward. When it cannot move further, release the pull of the hand-pull plate 105, and then remove the top blocks 208 on both sides of the placement plate 204. When the packaging bag to be inspected is relatively large, pull the hand-pull plate 105 to one side while holding the mouth-shaped plate 201 and move it backward. When it cannot move further, release the pull on the hand-pulling plate 105, then put new top blocks 208 on both sides of the placement plate 204, adjust the position of the mouth-shaped plate 201, and fix the writing pen 203 and the writing board 111 together with the device. When using, first poke the bottom of several packaging bags, observe the relative position of the poke position and the scale line, and then when poking the bottom of the packaging bag, the tip of the writing pen 203 should be at the upper end of the scale line. If it is not poked at the scale line, it is a packaging bag with unqualified sealing.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
