Description

Technical Field

[0001] The present application relates to the technical field of packaging equipment, and in particular to a packaging bag heat sealing machine. Background Art

[0002] Medical flat roll bags are often used in hospitals to store medical devices. When using them, you need to cut the medical flat roll bags of appropriate length according to the length of the medical devices, then put the medical devices into the flat roll bags, and use a heat sealer to seal the openings at both ends of the medical flat roll bags.

[0003] In the related art, a heat sealing device for packaging bag production and processing equipment mainly includes a frame, two parallel heat pressing strips and two parallel heating strips, and the heat pressing strips correspond to the heating strips one by one. The heat pressing strips are fixedly connected to the frame, and the heating strips are slidably arranged above the heat pressing strips in the vertical direction and can be pressed against the heat pressing strips. A cylinder for driving the heating strips to move is installed on the frame.

[0004] When heat-sealing a medical flat roll bag, the medical staff places one end of the opening of the medical flat roll bag on the heat pressing strip, and then the cylinder drives the heating strip to move downward until it is close to the heat pressing strip, and the heating strip is heated, so as to heat-seal one end of the opening of the medical flat roll bag, and then the cylinder drives the heating strip to move upward, and the medical staff repeats the above actions to heat-seal the other end of the opening of the medical flat roll bag. If the length of the medical flat roll bag to be heat-sealed is the same as the distance between the two heating strips, the medical flat roll bag can be placed between the two heating strips, and both ends of the opening of the medical flat roll bag can be heat-sealed at the same time.

[0005] However, the lengths of medical devices vary greatly, resulting in inconsistent lengths of cut medical flat roll bags, and the lengths vary greatly. When heat-sealing the medical flat roll bags, one open end is usually heat-sealed first, and then the other open end is heat-sealed, resulting in low heat-sealing efficiency. Summary of the invention

[0006] In order to enable a heat sealer to heat seal both ends of an opening of a medical flat roll bag at the same time, thereby improving the heat sealing efficiency of the medical flat roll bag, the present application provides a packaging bag heat sealer.

[0007] The present application provides a packaging bag heat sealing machine, which adopts the following technical solution:

[0008] A packaging bag heat sealing machine, comprising:

[0009] frame;

[0010] Two mutually parallel heat pressing strips, the heat pressing strips are slidably matched with the frame;

[0011] Two mutually parallel heating strips, the heating strips are slidably matched with the frame, and the sliding direction is parallel to the moving direction of the hot pressing strips, and the two heating strips can move in the vertical direction at the same time and abut against the two hot pressing plates one by one;

[0012] A driving assembly is used to drive two hot pressing strips to move in a vertical direction simultaneously.

[0013] By adopting the above technical solution, when heat-sealing a medical flat roll bag, the medical flat roll bag is placed between two heat pressing strips, and then the driving assembly drives the two heating strips to move downward and abut against the heat pressing strips, so as to heat-seal the openings at both ends of the medical flat roll bag at the same time. The heat pressing strip can move in the horizontal direction, so as to adjust the distance between the two heat pressing strips, so as to heat-seal the two openings of medical flat roll bags of different lengths at the same time, and the heating strip can move in the horizontal direction so that the heating strip can move downward to abut against the heat pressing strip.

[0014] Optionally, the heat pressing strip and the heating strip slide together in a vertical direction, and the sliding direction of the heat pressing strip is a horizontal direction.

[0015] By adopting the above technical solution, the heating strip and the hot pressing strip can move in the horizontal direction at the same time, so as to facilitate the adjustment of the position of the heating strip or the hot pressing strip. The hot pressing strip and the heating strip slide together in the vertical direction, so that the hot pressing strip is always aligned with the heating strip, and the operator does not need to adjust the position of the heating strip to align the heating strip with the hot pressing strip. The sliding direction of the hot pressing strip is the horizontal direction, so that the heating strip can slide in the vertical direction relative to the hot pressing strip.

[0016] Optionally, a blade is fixedly connected to the heating strip, and the blade is used to cut the edge of the medical flat roll bag.

[0017] By adopting the above technical solution, if the edge of the cut medical flat roll bag is uneven or skewed, the blade can trim the edge of the medical flat roll bag during heat sealing, so that the edge of the heat-sealed medical flat roll bag is neat.

[0019] By adopting the above technical solution, when heat-sealing the medical flat roll bag, the medical flat roll bag is placed above the first tensioning strip and the heating strip. When the heating strip abuts against the heat pressing strip, the first tensioning strip abuts against the second tensioning strip, so that the medical flat roll bags at both ends of the blade are clamped, thereby tensioning the medical flat roll bag at the blade, making it easier for the blade to cut the medical flat roll bag.

[0020] Optionally, two installation boxes are included, the installation boxes are slidably matched with the frame, and the sliding direction is parallel to the sliding direction of the hot pressing strip, and the two heating strips are slidably connected to the installation boxes along the vertical direction.

[0021] By adopting the above technical solution, the installation box provides an installation carrier for the heat strip.

[0022] Optionally, a locking piece for locking the position of the installation box is provided on the installation box.

[0023] By adopting the above technical solution, the locking piece can lock the installation box, thereby improving the stability of the heating strip during heat sealing and improving the accuracy of the heat sealing position.

[0024] Optionally, the installation box includes a first slider, a first slide groove is provided on the frame, the first slider is slidably matched with the first slide groove, and the locking piece is threadedly connected to the first slider and can be pressed against the inner wall of the first slide groove.

[0025] By adopting the above technical solution, the locking member can be rotated so that one end of the locking member can be pressed against the first sliding groove, thereby locking the position of the installation box, and the cost is low.

[0026] Optionally, the driving assembly includes a driving source, a connecting plate and a connecting rod, the driving source is installed inside the installation box, the output end of the driving source can move in the vertical direction and is connected to the connecting plate, the connecting plate is arranged inside the installation and is slidably connected to the installation box, one end of the connecting rod is connected to the connecting plate, and the other end passes through the installation box and is connected to the heating plate.

[0027] By adopting the above technical solution, the driving source is arranged inside the installation box, and the installation box can reduce the entry of dust and the like into the driving source, thereby increasing the service life of the driving source and reducing the maintenance cycle of the driving source.

[0028] Optionally, an elastic member is connected between the bottom wall of the connecting plate and the inner wall of the installation box.

[0029] By adopting the above technical solution, when the driving source drives the heating strip to move downward, the elastic member is compressed, exerting an upward force on the connecting plate, thereby playing a buffering role.

[0030] Optionally, the elastic member is sleeved on the outside of the connecting rod.

[0031] By adopting the above technical solution, the stress on the connecting plate is evenly distributed, thereby reducing the deformation of the connecting plate.

[0032] In summary, the present application includes at least one of the following beneficial effects:

[0033] 1. The heat strip can move in the horizontal direction to adjust the distance between the two heat strips to heat-seal the two openings of the medical flat roll bags of different lengths at the same time. The heating strip can move in the horizontal direction so that the heating strip can move downward to abut against the heat strip;

[0034] 2. If the edge of the cut medical flat roll bag is uneven or skewed, the blade can trim the edge of the medical flat roll bag during heat sealing, so that the edge of the medical flat roll bag after heat sealing is neat;

[0035] 3. When heat-sealing the medical flat roll bag, place the medical flat roll bag above the first tensioning strip and the heating strip. When the heating strip abuts against the heat-pressing strip, the first tensioning strip abuts against the second tensioning strip, so that the medical flat roll bags at both ends of the blade are clamped, thereby tensioning the medical flat roll bag at the blade, which is convenient for the blade to cut the medical flat roll bag;

[0036] 4. The driving source is arranged inside the installation box, which can reduce dust and the like from entering the driving source, thereby increasing the service life of the driving source and reducing the maintenance cycle of the driving source. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0041] The following is combined with Figure 1-3 This application is described in further detail.

[0042] A packaging bag heat sealing machine disclosed in the embodiment of the present application, referring to Figure 1 and Figure 2The packaging bag heat sealing machine includes a frame 1 and two mutually parallel mounting boxes 7. The frame 1 is provided with two mutually parallel first slide grooves 11. Two first sliders 72 are slidably fitted in the first slide grooves 11. The first sliders 72 are threadedly connected with locking members 71. The threaded holes connected to the locking members 71 penetrate the first sliders 72 in the vertical direction. The locking members 71 can press against the inner wall of the first slide grooves 11. The locking members 71 are bolts. The mounting boxes 7 are fixedly connected to the two opposite first sliders 72 in different first slide grooves 11.

[0043] When the first slider 72 slides, it can drive the two installation boxes 7 to slide along the first slide groove 11, so as to adjust the distance between the two installation boxes, and rotate the locking piece 71. When the locking piece 71 is pressed against the inner wall of the first slide groove 11, the corresponding first slider 72 is locked, so as to lock the position of the corresponding installation box 7.

[0044] Reference Figure 1 and Figure 3 The packaging bag heat sealing machine includes two drive assemblies 8, and the two drive assemblies 8 correspond to the two installation boxes 7 one by one. Since the installation method of the drive assembly 8 is the same as that of the installation box 7, the installation method of the drive assembly 8 and the installation is described below by taking one installation box 7 and a group of drive assemblies 8 as an example. The drive assembly 8 includes a connecting plate 82, two connecting rods 83 and two driving sources 81. The driving source 81 is an electric push rod. Two driving sources 81 are installed in parallel in the installation box 7. The output end of the driving source 81 is downward in the vertical direction, and the moving direction is the vertical direction. The output ends of the two driving sources 81 in the same installation box 7 are fixedly connected to the connecting plate 82, and the lower part of the connecting plate 82 is fixedly connected to the two connecting rods 83. The end of the connecting rod 83 away from the connecting plate 82 passes through the bottom wall of the installation box 7. The top and side walls of the installation box 7 are detachably connected by bolts, so as to facilitate the installation of the drive assembly 8 on the installation box 7.

[0045] Reference Figure 3 The connecting rod 83 is covered with an elastic member 84 , which is a spring. The two ends of the elastic member 84 are respectively connected to the bottom wall of the connecting plate 82 and the inner wall of the installation box 7 .

[0046] Reference Figure 3 The packaging bag heat sealing machine includes two heating strips 3, which are horizontally arranged in a direction perpendicular to the first slide groove 11, and the heating strips 3 are fixedly connected to two connecting rods 83 passing through the bottom wall of the same installation box 7.

[0047] The driving source 81 drives the connecting plate 82 to move in the vertical direction, and the connecting plate 82 drives the heating strip 3 to move in the vertical direction through the connecting rod 83. When the driving source 81 drives the connecting plate 82 to move downward, the elastic member 84 undergoes elastic deformation, exerting an upward force on the connecting plate 82, thereby playing a buffering role.

[0048] Reference Figure 1 and Figure 3 A second tensioning strip 6 and a blade 4 are fixedly connected to a side wall of the heating strip 3 away from the other heating strip 3. The second tensioning strip 6 is arranged along the length direction of the heating strip 3. The blade 4 is arranged between the second tensioning strip 6 and the heating strip 3, and the bottom end of the blade 4 extends out of the bottom wall of the second tensioning strip 6.

[0049] Reference Figure 3 A third slide groove 31 is provided at one end of the heating strip 3, and a third slider 22 is slidably fitted in the third slide groove 31. One end of the third slider 22 is fixedly connected to the hot pressing strip 2. The hot pressing strip 2 is arranged along the length direction of the heating strip 3, and the top wall of the hot pressing strip 2 can abut against the bottom wall of the heating strip 3.

[0050] Reference Figure 3 The side wall of the hot press strip 2 is fixedly connected with a first tensioning strip 5 , which is arranged along the length direction of the hot press strip 2 and can be pressed tightly against the second tensioning strip 6 .

[0051] Reference Figure 1 and Figure 3 Two second sliders 21 are fixedly connected to the bottom wall of the hot pressing strip 2, and two second slide grooves 12 are provided on the frame 1, which are parallel to the first slide groove 11. The two second sliders 21 slide in a one-to-one corresponding manner with the two second slide grooves 12, so that the hot pressing strip 2 can only slide along the second slide groove 12 in the horizontal direction.

[0052] The locking piece 71 is then rotated so that the locking piece 71 abuts against the inner wall of the first slide groove 11, thereby locking the first slide block 72. The openings at both ends of the medical flat roll bag are respectively placed above the corresponding hot pressure strip 2 and the first pressing strip, and the driving source 81 drives the heating strip 3 to move downward through the connecting plate 82 and the connecting rod 83, so that the heating strip 3 abuts against the hot pressure strip 2 below it, thereby heat-sealing the openings at both ends of the medical flat roll bag at the same time.

[0053] When the heating strip 3 abuts against the heat pressing strip 2, the first tensioning strip 5 and the second tensioning strip 6 abut against each other, thereby tensioning the medical flat roll bag at the blade 4, so that the blade 4 can cut the medical flat roll bag, making the edge of the heat-sealed medical flat roll bag neat.

[0054] The third slider 22 cooperates with the third slide groove 31 so that the hot pressing strip 2 is always located below the heating strip 3, and the hot pressing strip 2 can move with the heating strip 3, thereby facilitating the positioning of the hot pressing strip 2. The second slider 21 cooperates with the second slide groove 12 so that the hot pressing strip 2 can only slide in a plane, so that the heating strip 3 can move in a vertical direction relative to the hot pressing strip 2.

[0055] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
