Description

Technical Field

[0001] The present application relates to the technical field of filling machines, and in particular to a clamping device for a vertical filling machine. Background Art

[0002] A vertical filling machine is an automated packaging machine used to fill a predetermined amount (e.g., 100 ml) of bulk cosmetics into a plastic packaging bag and seal it. Existing vertical filling machines are sequentially provided with a bag opening station, a filling station, a flattening station, a sealing station, and a discharging station along the conveying direction of the frame, and the filling machine is provided with a bag clamping device for sequentially conveying the packaging bags to different stations.

[0003] The bag clamping device includes at least two sets of clamps, which are used to clamp the opposite sides of the packaging bag and then transfer the packaging bag to each workstation. However, when the packaging bag is actually opened, if the size of the packaging bag changes, the clamps may not clamp the packaging bag properly or clamp the packaging bag excessively during the bag opening and filling process, which affects the filling effect of the packaging bag. Utility Model Content

[0004] In order to maintain the filling effect of packaging bags of different sizes, the present application provides a clamping device for a vertical filling machine.

[0005] The present application provides a clamping device for a vertical filling machine using the following technical solution:

[0006] A clamping device for a vertical filling machine is installed on a frame and includes a clamping structure. The clamping structure includes a driving assembly, two clamping plates and two groups of clamping members. The two clamping plates are slidably installed on the frame. The driving assembly is used to drive the two clamping plates to approach each other. The clamping member includes two clamps, and the two clamps are respectively slidably installed on the clamping plates. The clamping member is provided with a fixing member for fixing the position of the clamp.

[0007] By adopting the above technical solution, when the filling machine is in operation, if the size of the packaging bag changes, the distance between the two groups of clamps can be changed by sliding the position of the clamp on the clamping plate, so as to clamp the packaging bags of different sizes on both sides of the width, thereby reducing the situation of over-clamping / under-clamping of the packaging bags and maintaining the filling effect of packaging bags of different sizes.

[0008] Optionally, a rubber column is provided on each side of the two clamps that are close to each other.

[0009] By adopting the above technical solution and arranging the rubber column, the friction force between the two sides of the packaging bag clamped by the clamping member can be increased, thereby reducing the possibility of the packaging bag slipping off the clamping member during the filling process.

[0010] Optionally, the chuck is provided with a sliding groove for plugging into the outer wall of the clamping plate, the outer wall of the clamping plate is provided with a dovetail block, and the inner wall of the sliding groove is provided with a dovetail groove for matching with the dovetail block.

[0011] By adopting the above-mentioned technical solution, the sliding groove of the chuck is sleeved on the outer wall of the clamping plate to facilitate changing the position of the chuck on the clamping plate; and the sliding cooperation between the dovetail block and the dovetail groove can increase the stability of the chuck on the clamping plate, thereby reducing the situation in which the sliding groove is detached from the clamping plate during the sliding process of the chuck on the clamping plate.

[0012] Optionally, the fixing member includes a screw, the clamp is provided with a thread groove, and the thread groove abuts against the sliding groove; the screw is installed in the thread groove to tighten against the outer wall of the clamping plate.

[0013] By adopting the above-mentioned technical solution, when the chuck needs to be fixed to the clamping plate, the screw is rotated in the thread groove toward one side of the clamping plate so that the screw is pressed against the outer wall of the clamping plate, thereby increasing the resistance of the chuck to slide on the clamping plate, thereby completing the fixation of the chuck on the clamping plate.

[0014] Optionally, a rubber strip is provided on one side of the clamping plate close to the thread groove.

[0015] By adopting the above technical solution, the head of the screw is pressed against the outer wall of the rubber strip when it rotates toward one side of the clamping plate, further increasing the friction between the screw and the side wall of the clamping plate and improving the stability of the clamp on the clamping plate.

[0016] Optionally, the fixing member includes a clamping block, a spring and an unlocking member, the inner wall of the sliding groove is provided with a first clamping groove, and the clamping block is movably installed in the first clamping groove; the spring is installed between the clamping block and the inner wall of the first clamping groove, and the spring is kept in a compressed state; the clamping plate is provided with a plurality of second clamping grooves for plugging the clamping blocks, and the unlocking member is used to cancel the plugging of the clamping block and the second clamping groove.

[0017] By adopting the above-mentioned technical solution, the plug-in cooperation between the clamping block and different first clamping grooves can fix the chuck on the clamping plate, reducing the free sliding of the chuck on the clamping plate; and by setting a spring, the elastic force of the spring drives the clamping block to be normally plugged into the second clamping groove, further increasing the stability of the chuck fixed on the clamping plate; the unlocking piece is used to cancel the plug-in cooperation between the clamping block and the second clamping groove, so as to facilitate the adjustment of the position of the chuck on the clamping plate to change the spacing between the two groups of clamps.

[0018] Optionally, the clamping structure is provided in two groups, and the two groups of clamping structures are installed on the frame and are spaced apart along the height direction of the frame.

[0019] By adopting the above technical solution, the two sets of clamping structures can fix the four corners of the packaging bag respectively, further increasing the stability of the packaging bag during the filling process and reducing the possibility of the packaging bag detaching from the clamping parts.

[0020] Optionally, the clamping plate is provided with scale lines.

[0021] By adopting the above technical solution and setting scale lines, the positions of the two clamps adjusted on the two clamping plates are kept consistent, thereby improving the adjustment efficiency of the clamps and reducing the possibility of over-clamping / under-clamping of the packaging bag.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. By sliding the clamps on the clamping plate, the distance between the two sets of clamps can be changed to clamp the width sides of packaging bags of different sizes, reduce the situation of over-clamping / under-clamping of packaging bags, and maintain the filling effect of packaging bags of different sizes;

[0024] 2. By providing a rubber strip, the head of the screw is pressed against the outer wall of the rubber strip to deform the rubber strip, thereby increasing the friction between the screw and the side wall of the clamping plate, thereby improving the stability of the clamp on the clamping plate.

[0030] The following is combined with Figure 1-4This application is described in further detail.

[0031] Embodiment 1:

[0032] The embodiment of the present application discloses a clamping device for a vertical filling machine.

[0033] Reference Figure 1 A clamping device for a vertical filling machine is installed on a frame 5, including two groups of clamping structures 1, which are spaced apart along the height direction of the frame 5 and are used to clamp the upper and lower sides of the packaging bag; the clamping structure 1 includes a movable component, two clamping plates 3 and two groups of clamping members 4, and the frame 5 is slidably installed with two linear modules 51, the sliding direction of the linear module 51 on the frame 5 is perpendicular to the conveying direction of the frame 5, the sliding seat conveying direction of the linear module 51 is in the same direction as the conveying direction of the frame 5, and the two clamping plates 3 are respectively fixed on the slide seats of the two linear modules 51.

[0034] The movable assembly includes two cylinders 21, which are respectively fixed to opposite sides of the frame 5, and the movable plugs of the two cylinders 21 are arranged opposite to each other; the movable plugs of the two cylinders 21 are respectively connected to the two linear modules 51. When the movable plugs of the cylinders 21 are activated, the two linear modules 51 can be brought closer to each other, so that the two clamping plates 3 can be brought closer to each other and clamp the opposite sides of the packaging bag.

[0035] Reference Figure 2 The clamping member 4 includes two clamps 41, which are respectively installed on the two clamping plates 3; the clamps 41 are provided with sliding grooves 42, which are sleeved on the outer walls of the clamping plates 3; the outer walls of the clamping plates 3 are fixed to the dovetail blocks 31, and the inner walls of the sliding grooves 42 are provided with dovetail grooves 43 for the dovetail blocks 31 to slide; the plug-in cooperation between the dovetail blocks 31 and the dovetail grooves 43 can increase the stability of the sliding of the clamps 41 on the clamping plates 3 and reduce the possibility of the clamps 41 being detached from the clamping plates 3.

[0036] A rubber column 44 is provided on the side where the two clamps 41 are close to each other. When the two clamping plates 3 are close to each other, the rubber columns 44 of the two clamps 41 can be pressed against the opposite sides of the packaging bag respectively, thereby increasing the friction between the packaging bag and the clamping member 4 and reducing the possibility of the packaging bag slipping off the clamping belt during the filling process.

[0037] The surface of the clamping plate 3 is provided with scale lines, which can make the two clamps 41 keep the same position adjusted to the two clamping plates 3, further reducing the situation of over-clamping / under-clamping of the packaging bag.

[0038] Reference Figure 3The clamp 41 is provided with a fixing member 6. In this embodiment, the fixing member 6 is configured as a screw 61 and a rubber strip 62. The clamp 41 is provided with a threaded groove 45, the threaded groove 45 is communicated with the sliding groove 42, and the screw 61 is threadedly installed in the threaded groove 45; the rubber strip 62 is adhered to one side of the clamping plate 3 close to the threaded groove 45, and the extension direction of the rubber strip 62 is in the same direction as the extension direction of the clamping plate 3.

[0039] When the clamp 41 needs to be fixed to the clamping plate 3, the screw 61 is rotated toward one side of the clamping plate 3 and pressed against the side wall of the rubber strip 62; and during the contact between the screw 61 and the rubber strip 62, the rubber strip 62 can be deformed, thereby increasing the friction between the screw 61 and the clamping plate 3, that is, completing the fixation between the clamp 41 and the clamping plate 3 and increasing the stability of the clamp 41 on the clamping plate 3.

[0040] The implementation principle of Example 1 of the present application is:

[0041] When the size of the packaging bag changes, the screw 61 is rotated to cancel the abutment of the rubber strip 62, and the clamp 41 slides freely on the clamping plate 3; when the distance between the two groups of clamps 4 is the same as the distance between the opposite sides of the packaging bag, the screw 61 is rotated again to abut against the rubber strip 62; thereby, the function of clamping both sides of the width of packaging bags of different sizes can be completed, reducing the situation of over-clamping / under-clamping of the packaging bags, and maintaining the filling effect of packaging bags of different sizes.

[0042] Embodiment 2:

[0043] The embodiment of the present application discloses a clamping device for a vertical filling machine.

[0044] Reference Figure 4 , the difference between the embodiment 2 of the present application and the embodiment 1 is that: the fixing member 6 includes a clamping block 63, a spring 64 and an unlocking member 65, the inner wall of the sliding groove 42 is provided with a first clamping groove 46, and the clamping block 63 is movably installed in the first clamping groove 46; the two ends of the spring 64 are respectively connected to the clamping block 63 and the inner wall of the first clamping groove 46, and the elastic force of the spring 64 drives the clamping block 63 to move toward the side away from the first clamping groove 46. The outer wall of the clamping plate 3 is provided with a plurality of second clamping grooves 32 for the clamping block 63 to be inserted, and all the second clamping grooves 32 are arranged at intervals along the length direction of the clamping plate 3. The plug-in cooperation between the clamping block 63 and the second clamping groove 32 can complete the fixation between the clamping head 41 and the clamping plate 3, and improve the fixing efficiency of the clamping head 41 and the clamping plate 3, and reduce the need to rotate the bolt multiple times to abut against the outer wall of the rubber strip 62.

[0045] The unlocking member 65 includes a first unlocking rod 651 and a second unlocking rod 652. The first unlocking groove 47 is provided on the inner wall of the first clamping groove 46. The extension direction of the first unlocking groove 47 is the same as the extension direction of the first clamping groove 46. The first unlocking rod 651 is slidably installed in the first unlocking groove 47 and is fixed to the clamping block 63. The outer wall of the chuck 41 is provided with a second unlocking groove 48 connected to the first unlocking groove 47. The second unlocking rod 652 is movably installed in the second unlocking groove 48. The second unlocking rod 652 is fixed to the first unlocking rod 651.

[0046] When the locking block 63 is inserted into the second locking groove 32, the second unlocking rod 652 protrudes from the outer wall of the chuck 41; when the chuck 41 needs to be slid on the clamping plate 3, the staff moves the second unlocking rod 652 toward one side of the second unlocking groove 48. Since the first unlocking rod 651 connects the second unlocking rod 652 and the locking block 63, the locking block 63 can be moved toward one side of the second unlocking groove 48 and the insertion of the second locking groove 32 can be cancelled, so as to facilitate the adjustment of the position of the chuck 41.

[0047] The above are 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.
