Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology, and in particular to a packaging machine film roll support frame that is easy to maintain. Background Technology

[0002] Roll film is a type of packaging film, typically available in roll form. Its materials are similar to those of packaging bags, primarily including PVC heat shrink film, OPP roll film, and PE roll film. Roll film has wide applications in the packaging industry, adaptable to various types of automated machinery, and offers excellent sealing and moisture-proof properties, making it suitable for packaging a wide range of products.

[0003] In the prior art, such as Chinese Patent No. CN211642764U, a film roll support frame in a packaging machine includes a support frame with a horizontal groove and a threaded rod. The threads on the threaded rod are symmetrically arranged. A support plate is on the threaded rod, and a rotating rod is connected to the support plate. The roll has a hexagonal insert. The rotating rod is slidably connected to the hexagonal insert. The rear rotating rod is connected to a motor. The support frame has a double-sealed bearing, and a heating roller is mounted on the double-sealed bearing. The heating roller has a through hole. A U-shaped tube is fixedly connected to the outer end of the double-sealed bearing. An air outlet pipe and an air return pipe are fixedly connected to the U-shaped tube respectively. The air outlet pipe and the air return pipe are fixedly connected to the two ends of an electric hot air blower. This utility model uses a turntable to drive the symmetrically arranged threaded rod to rotate. The threaded rod drives the support plate to move synchronously, and the support plate drives the rotating rod to move synchronously. This makes it easy to install and remove the hexagonal insert connected to the roll into the hexagonal insertion hole of the rotating rod, making it easy to replace different rolls.

[0004] While the above solution has the advantages mentioned above, its disadvantages are that the design lacks a process for disassembling and assembling the roller. Since a large amount of film is wound on the roller, long-term use will put great pressure on it, which will cause it to deform. Therefore, it needs to be replaced and maintained regularly. In addition, there is no maintenance for the bearing. When adding oil to the bearing, the internal structure needs to be disassembled separately, which increases the workload of the staff. Utility Model Content

[0030] Both of the track columns penetrate the three-head fixing plate, and positioning holes are provided on the two side plates of the three-head fixing plate.

[0031] The technical effect of adopting the above-mentioned further solution is that the guide of the track column causes the sliding of the three-headed fixing plate to be in the horizontal direction.

[0032] In a preferred embodiment, the maintenance component includes:

[0033] The filler port is located on one side of the fixed box and is threadedly connected to a sealing block;

[0044] The other end of the oil pipe is fitted onto the oil inlet end of the refueling pipe.

[0045] The technical effect of adopting the above-mentioned further solution is that the squeezed oil is transmitted to the roller bearing through the oil pipe.

[0046] In a preferred embodiment, a three-headed fixing plate is also slidably disposed on the slide rail.

[0047] The technical effect of adopting the above-mentioned further solution is that the other end of the roller is fixed by using another of the three-head fixing plates.

[0048] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0049] 1. In this utility model, when installing the roller, manually align multiple C-shaped buckles directly above the slots on the top of the fixing box to ensure that the multiple C-shaped buckles can be smoothly embedded into the fixing box. Manually pull the sleeve to make it move synchronously with the rectangular hollow block, and the direction of movement is along the guide direction of the track column to ensure that the three-head fixing plate is smoothly embedded into the multiple slots opened on one side of the fixing box. At the same time, the second tooth can cover the surface of multiple first teeth and second teeth. On the other side of the roller, manually pull the three-head fixing plate to embed it into one side of the fixing box.

At the same time, the other two inserts of the three-head fixing plate are respectively embedded into the other two slots on one side of the fixing box. At this time, screw multiple bolts into the two threaded holes on the top of the fixing box so that they pass through the other two inserts of the three-head fixing plate to achieve the fixing effect. This design connects the roller and the motor via a toothed connection, allowing the motor to drive the installed roller to rotate, while also enabling the roller to be easily removed for maintenance when the motor is no longer in control of the roller.

[0050] 2. In this invention, when the three-head fixing plate is used to fix the roller position, the screwed-in bolts will drive the pressure plate to move. When the pressure plate moves downward under pressure, it will stretch the two springs and simultaneously squeeze the oil inside the oil groove. This forces the oil through the oil pipe into the roller bearing, achieving the effect of lubricating and maintaining the roller bearing every time the roller is installed. When the bolts are removed, the oil pipe is taken out from the oil filling pipe at the top of the sleeve, and a rubber stopper is inserted. The oil groove uses its own elastic potential energy to drive the pressure plate to reset, at which point oil can be added to the inside through the oil filling port. This design automatically replenishes the roller bearing with the required oil during the roller fixing process, facilitating the maintenance process inside the sleeve and reducing the workload of the workers.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0063] Example 1:

[0064] Please see Figures 1-9 This embodiment provides a packaging machine film roll support frame that allows for easy maintenance by detaching and assembling the roll roller. The specific concept is as follows:

[0065] A maintenance-friendly packaging machine film roll support frame includes a base 1, with a bracket 101 mounted on the top of the base 1. The maintenance-friendly packaging machine film roll support frame also includes two fixing boxes 4, a roll roller 2, a bracket 2 3, and a fitting.

[0066] Among them, two fixing boxes 4 that play an auxiliary role are installed on both sides of the top of the bracket 101, and a slide rail 204 is installed on one side of one of the fixing boxes 4.

[0067] In addition, two threaded holes 409 are provided on the top and one side of the fixing box 4;

[0068] The roller 2 that needs to be added is installed on the top of the two fixed boxes 4;

[0069] Among them, the support bracket 2 3 is installed on the top of the base 1, and the motor 301 is installed on the top;

[0070] The fitting is installed on the output shaft of motor 301;

[0071] It should be noted that the fitting can move horizontally on the output shaft of the motor 301 and switch between two states. In the first state, the fitting can be embedded in the fixing box 4, so that the motor 301 controls the rotation of the roller 2 while fixing the position of the roller 2. In the second state, the fitting can be moved to pull it out of the fixing box 4, thereby detaching the motor 301 from the control of the roller 2 and releasing the fixation of the position of the roller 2.

[0072] As examples, in this embodiment, the fitting includes: a sleeve 201, a C-shaped buckle 202, multiple teeth 1 203, a sleeve 302, two track posts 306, multiple teeth 2 303, a rectangular hollow block 304, and a three-headed fixing plate 305.

[0073] Among them, the auxiliary sleeve 201 is respectively sleeved on the rollers on both sides of the winding roller 2, and the top is provided with a lubrication pipe, and the inner cavity is connected to the lubrication pipe.

[0074] The C-shaped buckle 202, which serves to fix the buckle, is fixedly installed at the bottom of the sleeve 201.

[0075] Among them, the multiple teeth 203 that play a rotating role are respectively set on the rollers on one side of the roller 2.

[0076] It should be noted that the ferrule 201 is fitted with a roller bearing 406.

[0077] Among them, the second support bracket 3, which plays a supporting role, is installed on the top of the base 1.

[0078] The sleeve 302, which serves as a connector, is fitted onto the output shaft of the motor 301.

[0079] Among them, the two track columns 306 that act as tracks are installed on one side of the bracket 2 3.

[0080] Among them, multiple teeth 303 that play a rotating role are mounted on the output shaft of motor 301.

[0081] It should be noted that the sleeve 302 is slidably connected to the output shaft of the motor 301, and the inner wall of the sleeve 302 can mesh with multiple teeth 1 203 and multiple teeth 2 303.

[0082] The rectangular hollow block 304, which plays an auxiliary role, is fitted onto the sleeve 302.

[0083] The three-headed fixing plate 305, which plays a fixing role, is installed on one side of the rectangular hollow block 304.

[0084] In addition, both track posts 306 penetrate the three-head fixing plate 305, and positioning holes 307 are provided on the two side plates of the three-head fixing plate 305.

[0085] It should be noted that the two positioning holes 307 on the three-head fixing plate 305 can be matched with the two threaded holes 409 respectively, so as to ensure that the bolt 1 407 and bolt 2 408 can be smoothly fixed to the three-head fixing plate 305 when screwed in.

[0086] In addition, a three-headed fixing plate 305 is also slidably installed on the slide rail 204.

[0087] In this embodiment, when installing the roller 2, multiple C-shaped buckles 202 are manually aligned directly above the slots on the top of the fixing box 4 to ensure that the multiple C-shaped buckles 202 can be smoothly embedded into the fixing box 4. The sleeve 302 is manually pulled to make it move synchronously with the rectangular hollow block 304, and the direction of movement is along the guide direction of the track column 306 to ensure that the three-head fixing plate 305 can be smoothly embedded into the multiple slots opened on one side of the fixing box 4. At the same time, the second tooth 303 can cover the surface of the multiple first teeth 203 and second teeth 303. On the other side of the roller 2, manually pull the three-head fixing plate 305 to embed it into one side of the fixing box 4. In this state, the middle insert of the three-head fixing plate 305 is embedded in the middle slot of one side of the fixing box 4 and engages with multiple C-shaped buckles 202. At the same time, the other two inserts of the three-head fixing plate 305 are embedded into the other two slots on one side of the fixing box 4. At this time, screw multiple bolts into the two threaded holes 409 on the top of the fixing box 4 so that they pass through the other two inserts of the three-head fixing plate 305 to achieve the fixing effect.

[0088] Example 2:

[0089] Please see Figures 1-9 Based on Example 1, this example provides a packaging machine film roll support frame that is easy to maintain and can protect bearings. The specific concept is as follows:

[0090] The easy-to-maintain packaging machine film roll support also includes a maintenance component, which is installed inside the fitting and can be activated to lubricate the components inside the fixing box 4 when the fitting is assembled.

[0091] As examples, in this embodiment, the maintenance components include: a filler port 401, an oil trough 402, a pressure plate 404, an oil pipe 405, and a bolt 407.

[0092] The auxiliary filling port 401 is located on one side of the fixed box 4 and is threadedly connected to a sealing block.

[0093] It should be noted that the channel inside the filler neck 401 is angled downwards to ensure that no oil leaks out when the sealing plug is inserted after adding the oil. This design is not shown in the figure to illustrate the internal structure.

[0094] The oil trough 402 is located inside the fixed box 4 and is connected to the oil filling port 401.

[0095] In addition, two round holes are opened at the top of the inner wall of the oil tank 402, and springs 403 are installed in both round holes.

[0096] It should be noted that both springs 403 are initially in a contracted state, so that the pressure plate 404 is located at the top of the inner wall of the oil trough 402.

[0097] Among them, bolt 407, which plays a connecting role, is threaded into one of the threaded holes 409, and bolt 408 is threaded into the other threaded hole 409.

[0098] It should be noted that when bolt 407 is screwed into threaded hole 409, it can pass through positioning hole 307 and directly contact pressure plate 404.

[0099] The pressure plate 404, which performs the squeezing action, is located at the top of the inner wall of the oil tank 402.

[0100] It should be noted that the top of the pressure plate 404 is connected to two springs 403.

[0101] Among them, the oil pipe 405, which serves as a connector, is connected to the oil tank 402.

[0102] In addition, the other side of the oil pipe 405 passes through one side of the ferrule 201 and is connected to the roller bearing 406.

[0103] It should be noted that the oil pipe 405 is made of high-density rubber, which ensures that there will be no oil leakage after the oil filling pipe is inserted into the top of the ferrule 201. This material is existing technology and will not be described in detail here.

[0104] In this embodiment, when the three-head fixing plate 305 fixes the position of the roller 2, the screwed-in bolt will drive the pressure plate 404 to move when it moves. When the pressure plate 404 moves downward under pressure, it will drive the two springs 403 to stretch, and at the same time squeeze the oil inside the oil tank 402, so that the oil is forced into the roller bearing 406 through the oil pipe 405, so as to achieve the effect of lubricating and maintaining the roller bearing 406 every time the roller 2 is installed. When the bolt is removed, the oil pipe 405 is taken out from the oil filling pipe at the top of the sleeve 201 and a rubber plug is inserted. The oil tank 402 uses its own elastic potential energy to drive the pressure plate 404 to reset. At this time, the oil can be added to the inside through the oil filling port 401.

[0105] Furthermore, it should be noted that in the above embodiments, the easy-to-maintain packaging machine film roll support frame may also include a battery pack, which provides power to the electronic devices involved in the easy-to-maintain packaging machine film roll support frame, such as the motor 301. Its circuit is connected using existing conventional connection methods, which will not be described in detail here.

[0106] Working principle:

[0107] When the operator needs to use the device, the roller 2 is manually placed above the two fixed boxes 4, and the C-shaped buckle 202 is smoothly inserted into the threaded hole 409 on the top of the fixed box 4. At this time, the rectangular hollow block 304 is manually pulled, which drives the sleeve 302 to move horizontally along the surface of the second tooth 303. Since the sleeve 302 can engage with multiple teeth 1 203, when the sleeve 302 is simultaneously covered on the surfaces of multiple teeth 1 203 and multiple teeth 2 303, the rectangular... The hollow block 304 drives the middle insert plate of the three-head fixing plate 305 to be inserted into two C-shaped buckles 202 through the slot on one side of the fixing box 4. At the same time, the other two insert plates of the three-head fixing plate 305 are respectively inserted into two other slots on one side of the fixing box 4. At this time, the bolts can be screwed into the threaded holes 409 on both sides of the top of the fixing box 4 and through the two threaded holes 409 on the surface of the three-head fixing plate 305 to achieve the function of fixing the position. On the other side of the roller 2, the three-head fixing plate 305 can be slid directly to perform the above operation. When the roller 2 needs to be replaced, unscrew the bolts and pull the sleeve 302 to reset it to the side of the motor 301. At this time, the sleeve 302 disengages from covering multiple teeth 203 and drives the three-head fixing plate 305 to be pulled out of the fixing box 4.

[0108] In use, insert the other end of the oil pipe 405 into the oil filling pipe at the top of the ferrule 201. When the bolt is screwed into the two threaded holes 409 at the top of the fixing box 4, the bottom of the bolt 407 will press the pressure plate 404 during the screwing process, causing the pressure plate 404 to move downwards in the vertical direction. In this state, the two springs 403 are in a stretched state, and the movement of the pressure plate 404 presses the oil in the oil tank 402. At this time, the oil in the oil tank 402 is transmitted to the roller bearing 406 through the oil pipe 405 to achieve the lubrication effect. When the bolt is removed, manually pull out the oil pipe 405 from the top of the ferrule 201, insert the rubber plug at the top of the ferrule 201, and unscrew the bolt. The two springs 403 in a stretched state use their own elastic potential energy to drive the pressure plate 404 to return to its original position. At this time, the rubber plug on the oil filling port 401 can be removed with a tool, and oil can be added to the oil tank 402.
