Description

Technical Field

[0001] The invention relates to the field of medicine packaging, and in particular to a medicine packaging composite film detection device. Background Art

[0002] Composite film refers to a film formed by combining various plastics with paper, metal or other plastics through adhesives. Composite bags made by heat-sealing composite films can be widely used in the packaging of powders, granules, Chinese herbal medicines, tablets, transdermal patches and medical devices. In actual use, the heat-sealed joints of composite films are easily damaged, which reduces the sealing performance of the heat-sealed joints of composite films, thereby affecting the quality of drugs in composite film packaging.

[0003] Most of the existing equipment tests the heat seal of composite film packaging by simply squeezing the composite film packaging filled with air to test the sealing performance of the heat seal. When the composite film packaging is transported and used in a medicine box, the composite film packaging will slide in the medicine box, causing the heat seal of the composite film packaging to be folded and worn, and the heat seal corners of the composite film packaging are more likely to be worn. However, it is difficult for existing equipment to fully simulate the conditions of the composite film packaging after daily use, which makes the sealing performance test of the composite film packaging after heat sealing insufficient.

[0004] In order to overcome the disadvantage that existing equipment is difficult to simulate the conditions of composite film packaging after daily use, thereby making the sealing performance test of composite film packaging after heat sealing insufficient, the present invention provides a medicinal packaging composite film detection device that can fully simulate the conditions of composite film packaging after daily use, thereby making the sealing performance test of composite film packaging more sufficient.

DETAILED DESCRIPTION

[0025] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0026] Embodiment 1: A device for detecting a composite film for pharmaceutical packaging, such as Figure 1-Figure 3 As shown, it includes a base plate 1, a mounting frame 2, a motor bracket 3, a driving motor 4, a pressurizing mechanism, a toggle mechanism and a clamping mechanism. The base plate 1 is fixedly connected to the mounting frame 2, two motor brackets 3 are welded to the mounting frame 2, and each motor bracket 3 is connected to a driving motor 4 by bolts. A pressurizing mechanism is provided on the base plate 1 and the mounting frame 2, and the pressurizing mechanism is used to pressurize the composite film package. The mounting frame 2 is provided with a toggle mechanism, and the toggle mechanism is used to toggle the composite film package. A clamping mechanism is provided on the toggle mechanism, and the clamping mechanism is used to clamp the composite film package.

[0027] The pressurizing mechanism includes a lower pressure frame 61, a pressure spring seat 62, a base 63 and a suction cup 64. The lower pressure frame 61 is slidably connected to the mounting frame 2. A pressure spring seat 62 is provided between the lower pressure frame 61 and the mounting frame 2. The pressure spring seat 62 is sleeved on the lower pressure frame 61. The base 63 is fixedly connected to the bottom plate 1. A suction cup 64 is respectively connected to the base 63 and the lower pressure frame 61 through threads.

[0028] The toggle mechanism includes a rotating disk 71, a sliding frame 72, a sliding rod 73 and a tightening bolt 74. Two rotating disks 71 are fixedly connected to the mounting frame 2, each rotating disk 71 is fixedly connected to the output shaft of a driving motor 4, and a sliding frame 72 is slidably connected to the mounting frame 2. Each sliding frame 72 has two guide grooves and two slide grooves. The two guide grooves of each sliding frame 72 are slidably connected to a rotating disk 71. Two sliding rods 73 are slidably connected between the two slide grooves of each sliding frame 72. Each sliding rod 73 is threadedly connected to two tightening bolts 74, and the four tightening bolts 74 are in contact with the sliding frame 72.

[0029] The clamping mechanism includes a clamping rod 75 and a compression spring 76. Each slide bar 73 is slidably connected to a clamping rod 75. Each clamping rod 75 is in contact with the base plate 1. Each clamping rod 75 is fixedly connected to a slide bar 73 with a compression spring 76.

[0030] At first, the compression spring 76 is in a compressed state. The two sides of the composite film package for testing are heat-sealed by the heat sealer to form a heat seal. There is air in the composite film package. The staff lifts the lower press frame 61. The upward movement of the lower press frame 61 will compress the pressure spring seat 62. The upward movement of the lower press frame 61 will drive a suction cup 64 to move upward. The staff places the heat-sealed composite film package on the base 63, and then the staff loosens the lower press frame 61. The lower press frame 61 and one of the suction cups 64 are reset under the drive of the pressure spring seat 62. The lower press frame 61 presses the composite film package tightly. The pressure spring seat 62 is in a compressed state. The staff turns the tightening bolt 74 to disengage the tightening bolt 74 from the sliding frame 72. When the locking cam 74 is in place, the locking cam 73 is in place and the locking cam 73 is in place, so that the locking cam 73 is in place and the locking cam 73 is in place. The cam 73 is in the state of being moved upward by the spring 76, and the spring 77 is in the state of being moved downward by the spring 78. When the cam 73 is in the state of being moved downward by the spring 76, the cam 73 is in the state of being moved downward by the spring 78. The two sides move back and forth, so that the heat seal of the composite film package is repeatedly folded, so that the composite film package can better simulate the actual situation and can more fully detect the sealing performance of the composite film package. After a certain number of cycles of the sliding frame 72 and the sliding rod 73, the staff turns off the drive motor 4 and the suction cup 64, and the rotating disk 71, the sliding frame 72, the sliding rod 73, the tightening bolt 74, the clamping rod 75 and the compression spring 76 stop moving. The suction cup 64 no longer absorbs the composite film package. When the sealing performance of the heat seal of the composite film package is damaged, the air in the composite film package will leak outward under the pressure of the pressure spring seat 62 and the lower pressure frame 61. When the sealing performance of the heat seal of the composite film package is intact, the air in the composite film package will not leak.

[0031] Embodiment 2: Based on embodiment 1, Figure 4-Figure 6 As shown, it also includes an extrusion mechanism, which includes a guide rod 81, a guide frame 82, a ball 821, a rotating rod 83 and an extrusion block 84. Two guide rods 81 are welded on the bottom plate 1, each guide rod 81 is slidably connected to a guide frame 82, each guide frame 82 is welded to a ball 821, each slide rod 73 is rotatably connected to a rotating rod 83, each rotating rod 83 has a spiral groove, and the spiral groove of each rotating rod 83 is slidably connected to a ball 821, and an extrusion block 84 is welded to the upper end of each rotating rod 83, and the extrusion block 84 is used to extrude the heat-sealed corners of the composite film packaging.

[0032] The horizontal movement of the slide bar 73 will drive the guide frame 82, the ball 821, the rotating rod 83 and the extrusion block 84 to move horizontally, and the slide bar 73 will drive the rotating rod 83 and the extrusion block 84 to move reciprocally up and down. The upward movement of the slide bar 73 will drive the rotating rod 83 and the extrusion block 84 to move upward, and the rotating rod 83 and the extrusion block 84 will contact the heat-sealed corners of the composite film package. The upward movement of the rotating rod 83 will cause the spiral groove on the rotating rod 83 to be squeezed by the ball 821 and cause the rotating rod 83 to rotate. The rotation of the rotating rod 83 will drive the extrusion block 84 to rotate, and the rotation of the extrusion block 84 will reciprocate and extrude the heat-sealed corners of the composite film package, further simulating the actual situation of the composite film package, and then further testing the sealing performance of the composite film package. The downward movement of the slide bar 73 will drive the rotating rod 83 and the extrusion block 84 to reset downward. The rotating rod 83 and the extrusion block 84 will rotate in the opposite direction when they reset downward, and then reciprocate in this way. After the detection is completed, the slide bar 73 stops moving, causing the rotating rod 83 and the extrusion block 84 to stop moving.

[0033] Embodiment 3: Based on embodiment 2, Figure 5-Figure 7 As shown, a friction mechanism is also included, which includes a moving rod 91 and a ball 92. Each clamping rod 75 is slidably connected to a moving rod 91, and each moving rod 91 is rotatably connected to a plurality of balls 92. The balls 92 are protruding from the lower surface of the moving rod 91, so that the plurality of balls 92 can contact the heat seal of the composite film package.

[0034] It also includes a pushing mechanism, which includes a limit block 94, a slide 95, a return spring 96 and a cam 97. A limit block 94 is welded to each slide bar 73, and a slide 95 is slidably connected to each limit block 94. Each slide 95 is slidably connected to a moving rod 91, and a return spring 96 is fixedly connected between each slide 95 and a slide bar 73. A cam 97 is welded to the upper end of each rotating rod 83, and each cam 97 is in contact with a slide 95.

[0035] The upward movement of the slide bar 73 and the rotating rod 83 will drive the limit block 94, the slide 95, the return spring 96 and the cam 97 to move upward. The upward movement of the clamping rod 75 will drive the moving rod 91 and the ball 92 to move upward. The moving rod 91 and the ball 92 will contact the heat seal of the composite film package. At the same time, the rotation of the rotating rod 83 will drive the cam 97 to rotate. The rotation of the cam 97 will squeeze the slide 95 to move the slide 95. The movement of the slide 95 will compress the return spring 96. The movement of the slide 95 will drive the moving rod 91 and the ball 92 to move. The movement of the ball 92 will rub the heat seal of the composite film package to simulate the wear on the heat seal of the composite film package, so that the sealing detection effect of the composite film package is further improved. The cam 97 is lifted and the cam 97 continues to rotate, which will cause the cam 97 to disengage from the slide 95. The slide 95 is reset under the drive of the reset spring 96. The reset of the slide 95 will drive the moving rod 91 and the ball 92 to reset, and then repeat this process. The downward movement of the slide bar 73 and the rotating rod 83 will drive the limit block 94, the slide 95, the reset spring 96 and the cam 97 to reset downward. The downward movement of the clamping rod 75 will drive the moving rod 91 and the ball 92 to reset downward, and then the slide bar 73, the rotating rod 83 and the clamping rod 75 will move upward again, and the above steps will be repeated. After the detection is completed, the slide bar 73, the rotating rod 83 and the clamping rod 75 stop moving, which will cause the moving rod 91, the ball 92, the slide 95, the reset spring 96 and the cam 97 to stop moving.

[0036] Embodiment 4: Based on the embodiment 3, Figure 1 As shown, an adjusting bolt 10 is also included, and two adjusting bolts 10 are connected to the mounting frame 2 through threads.

[0037] Initially, the staff rotates the adjusting bolt 10, which causes the adjusting bolt 10 to move downward, and the downward movement of the adjusting bolt 10 squeezes the pressure spring seat 62. The pressure of the pressure spring seat 62 can be adjusted according to the type of composite film packaging, thereby achieving better detection effect on the composite film packaging.

[0038] Embodiment 5: Based on Embodiment 4, Figure 3 As shown, a heating block 11 is also included, and each sliding rod 73 is fixedly connected to a heating block 11.

[0039] Initially, the staff turned on the heating block 11 according to the experimental process to simulate the sealing performance of the composite film packaging under high temperature weather conditions. The movement of the slide bar 73 would drive the heating block 11. After completing the test, the staff turned off the heating block 11.
