Technical Field

[0001] The invention relates to the technical field of hose packaging, and in particular to an automatic hose protective film winding device. Background Art

[0002] After the production of the hose is completed, it needs to be packaged, and the packaging steps are as follows: first, the hose is wound into a ring shape, and then a protective film is wound around the hose using a stretch film packaging machine. The main structure of the existing stretch film packaging machine includes a machine table and a C-frame. When the tire is supported on the machine table, due to the opening of the C-frame, one side of the tire will enter the C-frame, and then the C-frame rotates around its own axis, and the packaging film is continuously wound around the tire through its own rotation.

[0003] For example, in the Chinese patent application document with publication number CN118560761A and the name of the wrapping film packaging machine, when packaging tires, the wrapping packaging mechanism wraps the tires on the supporting conveying mechanism, the film roll temporary storage mechanism stores a plurality of wrapping film rolls, and the transfer mechanism transfers the wrapping film rolls between the film roll temporary storage mechanism and the wrapping film packaging mechanism. The clamping assembly clamps and releases the wrapping film, and the transfer assembly drives the clamping assembly to slide in the vertical direction, the horizontal direction parallel to the tire transmission direction, and the horizontal direction perpendicular to the tire transmission direction.

[0004] With regard to the above-mentioned related technologies, when a tire is packaged, the wrapping film packaging mechanism needs to be stopped, the wrapping film on the surface of the packaged tire needs to be manually cut off, and then the packaged tire is removed, and then the unpackaged tire is moved to the supporting conveying mechanism, the supporting conveying mechanism transports the tire to the wrapping film packaging mechanism, and one end of the wrapping film on the wrapping film packaging mechanism is fixed on the tire, and finally the wrapping film packaging mechanism is started to package the tire. This process is complicated in manual operation, and the packaging machine needs to be opened and closed repeatedly during the process of loading and unloading the tire, the processing process is not continuous, and the packaging efficiency of the tire is low.

[0020] In summary, compared with the prior art, the present invention includes at least one of the following beneficial technical effects: 1.

DETAILED DESCRIPTION

[0025] To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the following will be combined with the embodiments of the present invention. Figure 1-Figure 8 , the technical scheme of the embodiment of the present invention is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0026] This embodiment provides a hose protective film automatic winding device, referring to Figure 1 and Figure 2 A hose protective film automatic winding device includes a bracket 1, a fixing plate 11, a C-shaped plate 2, a first driving mechanism 3, a material roller 21, a supporting plate 4, a first rotation source 41, a second driving mechanism 5 and a cutting mechanism.

[0027] Reference Figure 1 , Figure 2 and Figure 3 The bracket 1 is erected on a horizontal plane, the fixed plate 11 is vertically fixedly connected to the bracket 1, the C-shaped plate 2 is rotatably connected to the fixed plate 11, and the first driving mechanism 3 is arranged on the fixed plate 11, which is used to drive the C-shaped plate 2 to rotate around its own central axis. The material roller 21 is arranged at one end of the C-shaped plate 2 and is rotatably connected to the side wall of the C-shaped plate 2. The outer side of the material roller 21 is wrapped with a protective film for packaging the hose 9. The support plate 4 is rotatably connected to the bracket 1, and the bracket 1 is used to support the hose 9. The support plate 4 includes a loading plate 44, a processing plate 42 and a discharging plate 43, and the loading plate 44, the processing plate 42 and the discharging plate 43 are arranged in a circular array around the central axis of the support plate 4. The bracket 1 is fixedly connected to the first rotation source 41, and the support plate 4 is fixedly sleeved on the driving shaft of the first rotation source 41. The loading plate 44, the processing plate 42 and the discharging plate 43 can rotate counterclockwise around the first rotation source 41 (refer to Figure 1 ), so that the positions of the loading plate 44, the processing plate 42 and the discharging plate 43 can be alternated.

[0028] Reference Figure 1 , Figure 2 and Figure 3 The processing plate 42 is arranged close to the C-shaped plate 2, and the C-shaped plate 2 can package the hose 9 located on the processing plate 42. The second driving mechanism 5 is arranged on the loading plate 44, the processing plate 42 and the discharging plate 43, and the second driving mechanism 5 is used to drive the hose 9 to rotate. The cutting mechanism is located between the processing plate 42 and the discharging plate 43. When the hose 9 on the processing plate 42 is packaged and transported to the discharging plate 43, the cutting mechanism cuts off the protective film. The cutting mechanism includes a linear drive 6 and a cutting knife 61. The first linear drive 6 is fixedly connected to the lower end of the bracket 1, and the cutting knife 61 is fixedly connected to the driving shaft of the linear drive 6.

[0029] The operator places the hose 9 coiled into a ring on the processing plate 42. The first rotation source 41 drives the support plate 4 to rotate, and rotates the processing plate 42 to the C-shaped plate 2. The first driving mechanism 3 starts to drive the hose 9 to rotate around its own central axis. At the same time, the second driving mechanism 5 drives the C-shaped plate 2 to rotate around its own central axis. When the C-shaped plate 2 rotates, it drives the material roller 21 to rotate around the hose 9, so that the protective film is wrapped around the hose 9.

[0030] During the packaging of the rubber rollers on the processing plate 42, the operator places the next rubber tube 9 to be packaged on the loading plate 44. After the rubber tubes 9 on the processing plate 42 are packaged, the first drive mechanism 3 and the second drive mechanism 5 stop running, and the first rotation source 41 drives the support plate 4 to rotate 120° counterclockwise, so that the rubber tubes 9 on the processing plate 42 are rotated to the discharge plate 43, and the rubber tubes 9 on the loading plate 44 are rotated to the processing plate 42.

[0031] Reference Figure 4After the rotation is completed, the rubber tube 9 on the processing plate 42 stretches the protective film on the material roller 21, so that the rubber tube 9 on the processing plate 42 and the material roller 21 hold the protective film tightly, that is, one end of the protective film is fixed on the rubber tube 9 at the processing plate 42, and then the first driving mechanism 3 is started again to drive the C-shaped plate 2 to rotate, and the second driving mechanism 5 is started again to drive the rubber tube 9 to rotate, so as to wrap the protective film around the rubber tube 9 on the feeding plate 44. After the C-shaped plate 2 wraps several turns of protective film around the surface of the rubber tube 9, the first linear drive 6 drives the cutting knife 61 to move upward to cut the protective film between the feeding plate 44 and the processing plate 42. After the rubber tube 9 on the processing plate 42 is packed, it is unloaded. The surface of the rubber tube 9 on the feeding plate 44 has been wrapped with several turns of protective film, and the protective film wrapped around the rubber roller is fixed on the surface of the rubber tube 9, that is, one end of the protective film is fixed on the surface of the rubber tube 9, and the first driving mechanism 3 and the second driving mechanism 5 continue to operate to pack the rubber tube 9 on the feeding plate 44.

[0032] Reference Figure 4 After the cutting blade 61 cuts off the protective film between the feeding plate 44 and the processing plate 42, a section of protective film will remain on the surface of the rubber tube 9 on both the feeding plate 44 and the processing plate 42, which is not wound around the rubber tube 9. At this time, after the rubber tube 9 on the feeding plate 44 is completely covered with the protective film, the first driving mechanism 3 and the second driving mechanism 5 will continue to wind the protective film to cover the section of protective film remaining on the surface of the rubber tube 9, thereby improving the packaging quality of the rubber tube 9 and reducing the possibility of the protective film on the surface of the rubber tube 9 being loosened.

[0033] By utilizing the position conversion among the loading plate 44, the processing plate 42 and the discharging plate 43, the packaged hose 9 can tighten the protective film on the surface of the hose 9 to be packaged, and at the same time, one end of the protective film can be automatically fixed on the surface of the unpackaged hose 9, and the protective film on the surface of the packaged hose 9 can be automatically cut off, thereby reducing the steps of the operator manually fixing one end of the protective film on the unpackaged hose 9 and cutting the protective film on the surface of the packaged hose 9.

[0034] In addition, while the operator is loading materials on the loading plate 44 and unloading materials on the discharging plate 43, the hose 9 on the processing plate 42 is being packaged, thereby achieving the function of the C-shaped plate 2 to package the hose 9 without stopping during the loading and unloading process of the hose 9, further improving the packaging efficiency of the hose 9.

[0035] When the loading plate 44 is removed and only the processing plate 42 and the discharging plate 43 rotate alternately, the function of packaging the hose 9 on the processing plate 42 when the discharging plate 43 is loading and unloading can also be realized, and the function of automatically fixing one end of the protective film on the surface of the unpackaged hose 9 and automatically cutting off the protective film on the surface of the packaged hose 9 can be realized. On the basis of the processing plate 42 and the discharging plate 43, a loading plate 44 is added. On the one hand, after the cutting knife 61 cuts off the protective film, the length of the protective film remaining on the surface of the hose 9 that is not wrapped around the hose 9 is shortened. On the other hand, the number of working stations for loading and unloading the hose 9 is increased, which is conducive to the orderly packaging of the hose 9.

[0036] Reference Figure 5 An adjusting screw 22 is slidably connected inside the material roller 21, and the adjusting screw 22 is threadedly connected to the C-shaped plate 2. The adjusting screw 22 is rotated to change the size of the positive pressure between the material roller 21 and the C-shaped plate 2, and then the size of the friction between the material roller 21 and the C-shaped plate 2 is adjusted, so that the C-shaped plate 2 has a friction buffer for the rotation of the material roller 21, so that when the material roller 21 can rotate to wrap the protective film around the surface of the hose 9, the material roller 21 can hold the protective film tightly, thereby improving the fit between the protective film and the hose 9, and thereby improving the packaging effect of the protective film on the hose 9.

[0037] Reference Figure 2 and Figure 5 The first driving mechanism 3 includes a support plate 4, a second rotation source 31, a driving wheel 32, a transmission wheel 33, a first conveyor belt 34 and a first friction wheel 35. The support plate 4 is vertically fixedly connected to the bracket 1, the second rotation source 31 is fixedly connected to the bottom of the bracket 1, the driving wheel 32 is fixedly sleeved on the driving shaft of the second rotation source 31, the transmission wheel 33 is rotationally connected to the support plate 4, the first friction wheel 35 is coaxially fixedly connected to the transmission wheel 33, the first friction wheel 35 abuts against the arcuate side surface of the C-shaped plate 2, and the first conveyor belt 34 is sleeved on the outer side surfaces of the driving wheel 32 and the transmission wheel 33.

[0038] The second rotation source 31 drives the first friction wheel 35 to rotate through the driving wheel 32 , the first conveyor belt 34 and the transmission wheel 33 in sequence. The first friction wheel 35 abuts against the C-shaped plate 2 to drive the C-shaped plate 2 to rotate.

[0039] Reference Figure 2 and Figure 5The fixed plate 11 is rotatably connected with a driven wheel 36, and the driven wheel 36 is coaxially fixedly connected with a second friction wheel 37, and the second friction wheel 37 abuts against the arc-shaped side surface of the C-shaped plate 2. The outer side surfaces of the transmission wheel 33 and the driven wheel 36 are sleeved with a second conveyor belt 38. The transmission wheel 33 drives the driven wheel 36 to rotate through the second conveyor belt 38, and the second friction wheel 37 and the driven wheel 36 rotate synchronously to drive the C-shaped plate 2 to rotate, and the second friction wheel 37 cooperates with the first friction wheel 35 to drive the C-shaped plate 2 to rotate, thereby improving the stability of the rotation of the C-shaped plate 2.

[0040] Reference Figure 1 and Figure 3 , three second driving mechanisms 5 are provided and are respectively provided at the loading plate 44, the processing plate 42 and the discharging plate 43. The second driving mechanism 5 includes a third rotation source 51, a driving gear 52, a connecting gear 53 and a material-resisting roller 54. The third rotation source 51 is fixedly connected to the lower bottom surfaces of the loading plate 44, the processing plate 42 and the discharging plate 43. The driving gear 52 is fixedly sleeved on the driving shaft of the third rotation source 51. The connecting gear 53 is rotationally connected to the support plate 4, and the connecting gear 53 is meshed with the driving gear 52. The material-resisting roller 54 is fixedly connected to the connecting gear 53, and the arc-shaped side wall of the material-resisting roller 54 is in contact with the outer side surface of the rubber hose 9. The third rotation source 51 drives the material-resisting roller 54 to rotate through the driving gear 52 and the connecting gear 53 in turn, and the material-resisting roller 54 drives the rubber hose 9 to rotate through friction.

[0041] Reference Figure 3 The upper surfaces of the loading plate 44, the processing plate 42 and the discharging plate 43 are rotatably connected with a plurality of supporting rollers 7, which are arranged in a circumferential array around the loading plate 44, the processing plate 42 and the discharging plate 43, respectively, and the supporting rollers 7 abut against the lower bottom surface of the rubber hose 9. The supporting rollers 7 support the rubber hose 9 to prevent the lower bottom surface of the rubber hose 9 from abutting against the upper surfaces of the loading plate 44, the processing plate 42 and the discharging plate 43, thereby reducing the friction generated by the relative movement of the rubber hose 9 with the loading plate 44, the processing plate 42 and the discharging plate 43 when the rubber hose 9 rotates.

[0042] Reference Figure 6 , Figure 7 and Figure 8The upper surfaces of the loading plate 44, the processing plate 42 and the discharging plate 43 are all fixedly connected with an air pump 81, and the outer sides of the loading plate 44, the processing plate 42 and the discharging plate 43 are all fixedly connected with a guide rail 8, and a gas delivery shell 82 is slidably arranged in the guide rail 8. An air delivery pipe 83 is connected between the air pump 81 and the gas delivery shell 82, and the air delivery pipe 83 is fixedly connected to the guide rail 8, and the gas delivery shell 82 is slidably connected to the air delivery pipe 83. The outer side surface of the gas delivery shell 82 is rotatably connected with a limiting roller 821, and the limiting roller 821 can abut against the outer side surface of the hose 9. A transmission rod 84 is vertically slidably connected inside the gas transmission housing 82, and a transmission rack 85 is fixedly connected to the side wall of the upper end of the transmission rod 84. The gas transmission housing 82 is hinged with a rotating seat 86 through a rotating pin 822. The rotating seat 86 is fixedly connected to the rotating pin 822. A transmission gear 87 that can mesh with the transmission rack 85 is fixedly sleeved on the outer side of the rotating pin 822. A pressing roller 88 is rotatably connected to the side of the rotating seat 86 away from the rotating pin 822, and the pressing roller 88 can abut against the upper surface of the hose 9.

[0043] When the operator places the rubber hose 9 on the support plate 4, the air pump 81 delivers air to the air delivery housing 82 through the air delivery pipe 83. The delivered air pushes the air delivery housing 82 to move along the length direction of the guide rail 8 close to the rubber hose 9. The limiting roller 821 moves synchronously with the air delivery housing 82 to abut against the outer side of the rubber hose 9, thereby clamping and limiting the rubber hose 9. The air pump 81 continues to deliver air to the air delivery housing 82. The air pushes the transmission rod 84 to move upward. The transmission rack 85 moves upward synchronously with the transmission rod 84. At the same time, the transmission rack 85 drives the transmission gear 87 to rotate clockwise (refer to Figure 7 ), the transmission gear 87 drives the rotating seat 86 to rotate clockwise through the rotating pin 822, and the pressing roller 88 rotates synchronously with the rotating seat 86 to abut against the upper surface of the hose 9, thereby limiting the hose 9 in the vertical direction. After the hose 9 is packaged, the air pump 81 extracts the air flow, so that the limiting roller 821 and the pressing roller 88 are separated from the hose 9 and reset.

[0044] As the C-shaped plate 2 drives the material roller 21 to rotate around the hose 9 and wraps the protective film around the surface of the hose 9, the C-shaped plate 2 makes a circular motion on the plumb plane. When the material roller 21 rotates upward, it drives the hose 9 to vibrate in the vertical direction through the protective film, causing the hose 9 to be displaced, which is not conducive to the stable fitting of the protective film and the surface of the hose 9, thereby having a negative impact on the packaging effect of the hose 9.

[0045] Therefore, by conveying air flow into the air delivery shell 82, on the one hand, it can drive the limiting roller 821 to abut the outer side surface of the hose 9 to limit the hose 9 in the horizontal direction. On the other hand, the air flow can drive the pressing roller 88 to rotate, so that the pressing roller 88 limits the hose 9 in the vertical direction, thereby reducing the displacement of the hose 9 when it is packaged, which is beneficial to the stable fitting of the protective film and the surface of the hose 9, thereby improving the packaging effect of the hose 9.

[0046] In addition, refer to Figure 4 After the cutting knife 61 cuts off the protective film between the feeding plate 44 and the processing plate 42, a section of protective film will remain on the surface of the hose 9 on the feeding plate 44 and the processing plate 42, which is not wrapped around the hose 9. For the protective film remaining on the processing plate 42, the second driving source drives the hose 9 to continue to rotate, and the hose 9 drives the remaining protective film to rotate and abut against the limiting roller 821 and the pressing roller 88. The limiting roller 821 and the pressing roller 88 squeeze the remaining protective film, so that the remaining protective film is fitted with the outer side of the protective film of the packaged hose 9, thereby further improving the packaging effect of the hose 9.

[0047] Reference Figure 7 A buffer torsion spring 89 is fixedly connected between the rotating pin 822 and the rotating seat 86. When the buffer torsion spring 89 is in a natural state, the material-repelling roller 54 is in a vertical state. After the airflow enters the gas delivery housing 82, the buffer torsion spring 89 is stretched, thereby generating resistance to the vertical upward movement of the transmission rod 84 through the rotating pin 822, the transmission gear 87 and the transmission rack 85, and then generating buffer resistance to the clockwise rotation of the pressing roller 88, thereby achieving the operation steps of the limiting roller 821 first contacting the outer side surface of the hose 9, and then the pressing roller 88 contacting the upper surface of the hose 9, preventing the pressing roller 88 from contacting the hose 9 first and then moving along the radial direction of the hose 9 with the gas delivery housing 82 to generate friction on the hose 9.

[0048] The implementation principle of the automatic hose protective film winding device of the embodiment of the present invention is as follows: the operator places the hose 9 wound into a ring on the processing plate 42, the first rotation source 41 drives the support plate 4 to rotate, the processing plate 42 is rotated to the C-shaped plate 2, the hose 9 and the C-shaped plate 2 rotate, and the protective film is wound on the hose 9. After the hose 9 on the processing plate 42 is packaged, the first rotation source 41 drives the support plate 4 to rotate 120°, so that the hose 9 on the processing plate 42 is rotated to the discharge plate 43, the hose 9 on the processing plate 42 stretches the protective film on the material roller 21, so that one end of the protective film is fixed on the hose 9 at the processing plate 42, and then the first driving mechanism 3 is started again to drive the C-shaped plate 2 to rotate, and the second driving mechanism 5 is started again to drive the hose 9 to rotate, so that the protective film is wound on the hose 9. After the C-shaped plate 2 wraps several circles of protective film around the surface of the hose 9, the first linear drive 6 drives the cutting knife 61 to move upward to cut off the protective film between the loading plate 44 and the processing plate 42. The hose 9 on the processing plate 42 is packaged and unloaded.
