Description

Technical Field

[0001] The utility model relates to the technical field of film blowing machines, and more specifically to a winding device of a horizontal pneumatic stretch film blowing machine. Background Art

[0002] The film produced by the film blowing machine is suitable for various high-end film packaging. Due to its excellent barrier properties, it can preserve freshness, prevent moisture and frost, isolate oxygen, and be oil-resistant. It can be widely used in light and heavy packaging, such as various fresh fruits, meat products, pickles, fresh milk, liquid beverages, and medical supplies.

[0003] At present, most of the film blowing machines need to use a winding device to wind the film, but the existing winding settings are all engaged by gears and tooth grooves, and are tightened and wound on the outside by a tension spring. However, due to the tightening force of the spring, when the distance between the winding roller and the active roller gradually increases, the tension of the spring also increases accordingly, which will cause small rolls to be unable to be wound and large rolls to be wound too tightly, resulting in uneven tightness. At the same time, the table of the winding roller in the existing one is set at an inclined surface due to the setting of the spring, so that the translational winding phenomenon cannot be achieved during winding, and the existing winding operation requires manual pulling and unwinding of the material, but because the gravity of the blown film after winding is relatively large, it also brings a certain burden to personnel when carrying it. For this reason, this scheme proposes a horizontal pneumatic stretching film blowing machine winding device. Utility Model Content

[0010] A further improvement is that the upper end surfaces of the second base and the sliding plate are both arranged as horizontal surfaces.

[0011] A further improvement is that: the driving member 1 includes a connecting plate 1 rotatably connected between the inner walls of the base 2, and positioning grooves 2 are provided on the side walls at both ends of the connecting plate 1.

[0013] A further improvement is that: the driving member 2 includes a connecting plate 2 rotatably connected to the outer end of the base 2, a support groove is provided on one side of the top end of the connecting plate 2, the outer end of the connecting plate 2 is rotatably connected to the connecting member, the outer end of the base 2 is installed with a cylinder 2, the telescopic end of the cylinder 2 is fixedly connected to the connecting member, and the other end of the cylinder 2 is connected to the air pump through an air pipe.

[0014] 3. Beneficial effects:

[0015] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects:

[0016] The utility model has a reasonable design and adopts the automatic operation of the cylinder to replace the existing winding step through the toothed gear and spring tension, so as to achieve a smoother and more uniform winding of the blown film roll and save more manpower;

[0017] When in use, the personnel first places an unwound take-up piece between the inner walls of the support members, waits for the film to be rolled up, and then rotates the support member so that the support member carries a take-up piece and is located between the upper side of the sliding plate and the inner wall of the driving member. Then, the personnel releases the limitation of the support member, causing one corner of the support member to rotate so that the bottom of the take-up piece is no longer limited by the support member. At this time, the personnel can lift the support member upward and rotate it to the initial position, and abut against the surface of the limit block, and then restore one corner of the support member to its initial state and lock it. Then, a take-up piece of unwound blown film is placed inside for standby, so that when the take-up piece above the sliding plate finishes film rolling, the personnel can directly cut the blown film and roll it onto the surface of the take-up piece above the support member, thereby realizing continuous film rolling operation.

[0018] During this period, as the winding piece between the inner wall of the driving part increases with the winding of the blown film, the cylinder 1 installed inside the driving part is in a negative pressure state in the initial state. Therefore, as the winding thickness of the blown film increases, the distance between the winding piece and the driving end gradually increases. After the tightening thickness reaches the requirement, the personnel touches the corresponding button on the top of the control console to prompt the cylinder 1 inside the driving part to inflate, prompting the driving part 1 to rotate as a whole. Due to the limit of the driving part 1, the winding piece is synchronously pushed to the end of the base 2 until it is supported by the notch above the driving part 2. Finally, the personnel touches another control button on the control console again, so that the driving part 2 drives the winding piece to rotate again, so that the winding piece can be located above the ground, which is more convenient for personnel to take and put.

[0019] At the same time, in the winding operation of this scheme, the overall winding direction of the winding piece is horizontal, and the pneumatic extension of the cylinder automatically adjusts the distance between the winding piece and the driving end, and is no longer affected by the uneven winding force caused by the setting of the inclined table due to the influence of spring tension in the existing scheme. Compared with the existing technology, the plastic film of this scheme is flatter after winding, and the tightness is consistent from small rolls to large rolls. There is no breakage during printing, especially for printing multi-color patterns, which is better for color registration, less waste film is wasted during bag making, and more manpower is saved.

[0020] It should be noted that the structures not introduced in the present invention do not involve the design points and improvement directions of the present invention, and are the same as the existing technology or can be implemented by using the existing technology, so they are not described in detail here.

Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0036] In this utility model, unless otherwise expressly specified or limited, the terms "installed," "connected," "connected," "fixed," "provided with," "provided on," etc. should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integral connection; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; or internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in this utility model based on specific circumstances. Example

[0037] See also Figure 1-5 , a horizontal pneumatic stretch film blowing machine winding equipment, including a base 1, a driving end 2 is installed between the inner walls of the base 1, and support members 3 are sleeved on the left and right sides of the driving end 2, a limiting block is fixedly connected to the side wall of the base 1, and the limiting block is located on the rear side of the support member 3, the side end of the base 1 is fixedly connected to a base 2 5, and a sliding plate 6 is fixedly connected to the side wall of the base 2 5, a driving member 7 is rotatably connected between the inner walls of the base 1, and a winding member 8 is provided between the upper inner walls of the driving member 7, a driving member 2 9 and an air pump 10 are installed on the outer end of the base 2 5, and the air pump 10 is pneumatically connected to the driving member 2 9, and a console 11 with multiple groups of corresponding button settings is installed on the upper end of the air pump 10.

[0038] More specifically, the upper end surfaces of the second base 5 and the sliding plate 6 are both arranged in a horizontal plane.

[0039] In this embodiment, the structure of the driving end 2 is: a coupling, a driving roller, and a transmission chain assembly, wherein the coupling is a fixed shaft, the driving shaft is sleeved on the surface of the coupling through a bearing shaft, and a transmission chain assembly is sleeved on one side for driving, and the support member 3 is sleeved on the outside of the coupling of the driving end 2.

[0040] During use, this solution enables the existing blown film to be wound more evenly and evenly during the winding operation, and saves more manpower. In this embodiment, the automatic operation of the cylinder is used to replace the existing winding step by the toothed gear and spring tension, so that the blown film roll can be wound more evenly and evenly, and more manpower is saved.

[0041] When the film is rolled up, the operator first places the unrolled film reel 8 between the inner walls of the support member 3. After the film is rolled up, the operator rotates the support member 3 to cause the support member 3 to carry the unrolled film reel 8 between the upper side of the sliding plate 6 and the inner wall of the driving member 7. Then, the operator releases the restriction of the support member 3 to cause one corner of the support member 3 to rotate so that the bottom of the film reel 8 is no longer restricted by the support member 3. At this time, the operator can lift the support member 3 upward and rotate it to the initial position, and abut against the surface of the limit block, and then restore one corner of the support member 3 to its initial state and lock it. Then, the unrolled film reel 8 is placed inside for standby, so that when the film reel 8 above the sliding plate 6 is rolled up, the operator can directly cut the film and roll it onto the surface of the reel 8 above the support member 3, thereby realizing continuous film rolling operation.

[0042] During this period, as the reeling piece 8 between the inner walls of the driving piece 7 increases with the amount of film being rewound, the cylinder 1 73 installed inside the driving piece 7 is in a negative pressure state in the initial state. As the thickness of the film being rewound increases, the distance between the reeling piece 8 and the driving end 2 gradually increases. After the tightening thickness reaches the requirement, the personnel touches the corresponding button on the top of the control console 11 to prompt the cylinder 1 73 inside the driving piece 7 to perform an inflation operation, prompting the driving piece 7 to rotate as a whole. Due to the limit of the driving piece 7, the reeling piece 8 is synchronously pushed to the end of the base 2 5 until it is supported by the notch above the driving piece 2 9. Finally, the personnel touches another control button on the control console 11 again, so that the driving piece 2 9 drives the reeling piece 8 to rotate again, so that the reeling piece 8 is located above the ground, which is more convenient for personnel to take and put.

[0043] At the same time, in the winding operation of this scheme, the overall winding direction of the winding piece 8 is horizontal, and the pneumatic extension of the cylinder automatically adjusts the distance between the winding piece 8 and the driving end 2, and is no longer affected by the uneven winding force caused by the setting of the inclined table due to the influence of spring tension in the existing scheme. Compared with the existing technology, the plastic film of this scheme is flatter after winding, and the tightness is consistent from small rolls to large rolls. There is no breakage during printing, especially for printing multi-color patterns, better color registration, less waste film is wasted during bag making, and more manpower is saved.

[0044] See also Figure 1-3 The support member 3 includes a ram horn seat 31 sleeved and installed on the left and right sides of the driving end 2. A threaded groove 32 is provided on the upper end of one side of the ram horn seat 31. The threaded pattern inside the threaded groove 32 is half set. The upper end of the other side of the ram horn seat 31 is fixedly connected to a support frame 33. A positioning column 34 is threadedly connected between the inner walls of the threaded groove 32. The upper center end of the positioning column 34 is fixedly connected to a positioning frame 35. A positioning groove 1 36 is provided on the side end of the positioning frame 35. A positioning shaft 37 is movably connected between the inner walls of the positioning groove 1 36. The left and right ends of the positioning shaft 37 are fixedly connected to positioning plates 38, and the top ends of the two positioning plates 38 are fixedly connected to connecting blocks 39.

[0045] In this solution, under the setting of the support member 3, the next winding roller or multiple winding rollers can be placed as spares, so that when the winding roller is winding up a lot of blown film, the personnel can cut off the blown film in time, so that the blown film is attached to the next winding roller, so as to achieve uninterrupted winding operation;

[0046] When in use, the personnel can place the winding member 8 in the limit groove formed between the positioning plate 38 and the support frame 33 as a standby. When the winding member 8 at this place is in use, the personnel can rotate the horn seat 31 so that the winding member 8 is rotated to the horizontal surface of the sliding plate 6. Then, the personnel pulls the connecting block 39 to prompt the positioning plates 38 on both sides to drive the positioning shaft 37 to slide to the top of the positioning groove 1 36. At the same time, the positioning plate 38 is completely located outside the thread groove 32. The personnel loosens the connecting block 39 at this time. Under the action of gravity, the positioning plate 38 and the connecting block 39 drive the positioning shaft 37 to rotate 90 degrees and be vertically located on the lower side of the winding member 8. At this time, the personnel can lift the thread groove 32 as a whole and restore the horn seat 31 to its original shape so that the next winding roller can be placed for standby operation.

[0047] When the ram horn seat 31 returns to its original state, in order to ensure that the winding piece 8 can be stably placed in the limiting groove formed between the positioning plate 38 and the support frame 33, the personnel can flip the positioning plate 38 again so that it is in the same horizontal plane as the thread groove 32, and then move the positioning plate 38 downward so that the two are outside the positioning frame 35 and are received between the thread groove 32 under the limitation of the positioning shaft 37. In this way, the position of the positioning plate 38 is limited to prevent the winding piece 8 from rotating when it is placed, thereby ensuring the stability of the winding piece 8 after it is placed;

[0048] At the same time, in this solution, due to the use of a threaded arrangement, the positioning column 34 as a whole can be freely disassembled and assembled in the threaded groove 32, which is convenient for maintenance and replacement by personnel.

[0049] See also Figure 1 and 4 -5, the driving member 7 includes a connecting plate 71 rotatably connected between the inner walls of the base 2 5, and positioning grooves 72 are provided on the side walls of the left and right ends of the connecting plate 71.

[0053] When the winding roller 81 is located inside the support groove 92, the person again presses another button on the top of the touch control console 11, so that the cylinder 2 93 is also inflated, causing the telescopic end of the cylinder 2 93 to also extend, and through the connection operation of the connecting piece 94, the connecting plate 2 91 is caused to rotate on the outside of the base 2 5, so that the winding piece 8 as a whole is located above it at a lower level relative to the ground, which is convenient for the person to take it away and greatly reduces the labor burden of the person.
