Description

Technical Field

[0001] The utility model relates to the technical field of bundling and packaging equipment, in particular to a bundling and packaging mechanism with an independent chain tray belt feeder. Background Art

[0002] In the early 1960s, with the emergence of polypropylene materials, foreign countries successfully developed polypropylene plastic strapping machines, which gradually replaced steel strapping in many fields, especially in the light industry, making strapping machines rapidly popular;

[0003] China's automatic baling machines began to develop in the mid-1980s, and were initially promoted in the book and newspaper distribution departments. In recent years, they have developed very rapidly and have been widely used in light industry, food, foreign trade, department stores, printing, medicine, chemical industry, post and telecommunications, textile and other industries.

[0004] The strapping machine, also known as the baler or strapping machine, is a machine that wraps the product or package with strapping tape, then tightens it and connects the two ends by melting them through thermal effects or using buckles and other materials. The function of the strapping machine is to make the plastic tape close to the surface of the bundled package, ensuring that the package does not fall apart during transportation and storage due to loose strapping, and at the same time making the strapping neat and beautiful.

[0005] When existing strapping and packing mechanisms convey and feed the strapping belt, they mostly use a small gear set for transmission. However, due to the large number of gears in the small gear set, the strapping belt is prone to jamming during the conduction and steering process. After the strapping belt is jammed, the strapping belt needs to be cut off or replaced with a new one. This process will cause a certain amount of material waste and reduce the strapping efficiency of the strapping machine. For this reason, the utility model proposes a strapping and packing mechanism with an independent chain disc for feeding the strapping belt. Utility Model Content

[0006] The utility model aims to provide a strapping and packing mechanism with an independent chain tray and belt conveyor to solve the problems raised in the above-mentioned background technology.

The limiting channel set in the chain disk limiting channel can effectively limit the two sides of the strapping belt, effectively preventing the strapping belt from falling off the belt feeding chain disk, improving the stability and safety of the strapping belt, and having a better use effect.

[0017] At this time, the belt feeding motor can rotate, and when the belt feeding motor rotates, it drives the belt feeding chain disc to rotate, so that the strapping belt can be tensioned and conveyed through the rotation of the belt feeding chain disc.

[0027] See also Figure 1-3The utility model provides an embodiment: a strapping and packing mechanism with an independent chain-disk belt feeder, comprising a frame 1, a belt feeder motor 6 is fixedly mounted on one side of the back of the frame 1 by fixing bolts, a belt feeder chain disc 2 is fixedly mounted on the output shaft of the belt feeder motor 6, a chain disc limiting channel 3 is arranged around the outer periphery of the belt feeder chain disc 2, limiting protrusions are arranged on both sides of the chain disc limiting channel 3, a half-circle outer conveying chain 4 is arranged around the outer wall of one side of the belt feeder chain disc 2, a plurality of evenly distributed transmission rollers 5 are installed in the middle of the outer conveying chain 4, and a belt feeder channel 7 is arranged below the belt feeder chain disc 2 and at the belt outlet end of the outer conveying chain 4;

[0028] When the belt feeding structure of this chain disk structure design is used, the strapping belt can enter the chain disk limiting channel 3 between the belt feeding chain disk 2 and the outer conveying chain 4 through the belt inlet on the upper part of the belt feeding chain disk 2. The limiting channel set in the chain disk limiting channel 3 can effectively limit the two sides of the strapping belt, effectively preventing the strapping belt from escaping from the belt feeding chain disk 2, improving the stability and safety of the strapping, and having a better use effect.

[0029] At this time, the belt feeding motor 6 is arranged to rotate, and when the belt feeding motor 6 rotates, the belt feeding chain disc 2 is driven to rotate, so that the strapping belt can be tensioned and conveyed through the rotation of the belt feeding chain disc 2. After rotating a certain angle, the strapping belt can be conveyed from the top end to the belt feeding channel 7 at the tail end;

[0030] By arranging an outer conveying chain 4 outside the belt conveying chain plate 2, the outer wall of the strapping belt can be pressed and conveyed by the driving roller 5 of the outer conveying chain 4, so as to effectively prevent slipping, and the driving roller 5 can rotate when the strapping belt is conveyed, and the friction can be effectively reduced by rolling contact, thereby increasing the smoothness of the strapping belt during conveying, reducing the resistance, and having a better strapping effect;

[0031] The utility model replaces the multi-gear belt feeder of the existing strapping mechanism with an independent chain plate rotary belt feeder, thereby effectively avoiding the situation that the belt is stuck during the steering process due to too many gears. The chain plate rotates from top to bottom to convey, which can effectively improve the smoothness during steering and avoid the strapping belt from getting stuck during steering, thereby avoiding the situation that the strapping belt is cut and replaced after getting stuck, thereby improving the utilization efficiency of materials, avoiding material waste, and effectively improving the overall strapping efficiency of the strapping machine, which is more practical.

[0032] A bottom plate 10 is provided at the tail end of the belt feeding channel 7, and a friction buckle assembly 11 is provided above the bottom plate 10. The friction buckle assembly 11 can perform downward friction buckle processing. A right pressing knife assembly 8 and a left pressing knife assembly 9 are respectively provided on both sides of the friction buckle assembly 11. The right pressing knife assembly 8 and the left pressing knife assembly 9 can be used to press and fix the left and right ends of the strapping belt, thereby improving the stability during buckle making and preventing the strapping belt from moving. An upper mounting plate 12 is fixedly installed above the frame 1, and a lateral displacement judgment assembly 13 is fixedly installed on the upper mounting plate 12;

[0033] The right pressing knife assembly 8 and the left pressing knife assembly 9 have the same structural dimensions.

[0034] In this embodiment, the right knife pressing assembly 8 includes a knife pressing cylinder 801, which is fixedly installed inside the frame 1, and the output rod of the knife pressing cylinder 801 is fixedly installed with a connecting seat 802, and a knife pressing rod 803 is rotatably installed on the connecting seat 802 through a rotating shaft;

[0035] Furthermore, a knife pressing head 804 is rotatably mounted on one end of the knife pressing rod 803 away from the connecting seat 802 via a rotating shaft;

[0036] With this structural design, when it is necessary to perform knife pressing, the knife pressing cylinder 801 can be extended. When the knife pressing cylinder 801 is extended, the connecting seat 802 at its top will be lifted, and at the same time, the knife pressing rod 803 will be lifted synchronously with the connecting seat 802, and the other end of the knife pressing rod 803 will be lowered relatively. The lowered end of the knife pressing rod 803 drives the knife pressing head 804 to descend, so that the strapping belt on the bottom plate 10 is tightened by the descending knife pressing head 804.

[0037] In this embodiment, the friction buckle assembly 11 includes a driving cylinder 1101, which is fixedly mounted on the lower surface of the upper mounting plate 12, and the output rod of the driving cylinder 1101 is fixedly mounted with a pneumatic rod 1102, and the bottom tail end of the pneumatic rod 1102 is fixedly mounted with a friction pressing knife 1103, and the outer wall of the friction pressing knife 1103 close to the left pressing knife assembly 9 is provided with a cutting knife (blocked in the figure, not shown);

[0038] The pneumatic rod 1102 is extended by the provided driving cylinder 1101, thereby driving the friction pressing knife 1103 to descend through the extension of the pneumatic rod 1102. After the friction pressing knife 1103 descends, it is pressed down and contacted with the strapping belt on the bottom plate 10, and friction welding is performed to make a buckle (this is a mature friction head making technical solution of the existing strapping machine, and this manual will not elaborate on it in detail).

[0039] In this embodiment, the lateral displacement judgment component 13 includes a lateral displacement slide plate 1301, a first spring connector 1302 is provided on one side of the lateral displacement slide plate 1301, and a slide plate return spring 1303 is fixedly installed between the first spring connector 1302 and the upper mounting plate 12;

[0040] Furthermore, a detection swing rod 1305 is hinged at the front end of the side shift slide 1301, a second spring connector 1304 is fixedly installed at the top of the detection swing rod 1305 and located on the upper surface of the upper mounting plate 12, and the detection swing rod 1305 and the second spring connector 1304 are fixedly connected via a swing rod return spring 1306;

[0041] Furthermore, side sliding rails 1307 are installed on both sides of the upper surface of the upper mounting plate 12, and side sliding seats are provided on both sides below the side sliding plate 1301, and the side sliding plate 1301 is slidably connected to the side sliding rails 1307 through the side sliding seats;

[0042] The side shift detection switch (blocked in the figure, not shown) is also included. The side shift detection switch is fixed on the frame 1. When the side shift slide plate 1301 is not shifted sideways, the lower end of the detection swing rod 1305 contacts the side shift detection switch.

[0043] The working principle of the side shift judging component 13 is as follows: the strapping belt passes through the side shift judging component 13 and enters the belt inlet on the upper part of the belt feeding chain plate 2. During the strapping process, the strapping belt first contacts the bundle and is further tightened. The tension of the strapping belt on the bundle reacts on the side shift slide plate 1301, causing the side shift slide plate 1301 to shift sideways relative to the upper mounting plate 12. The side shift detection switch disengages from the detection swing rod 1305. After reaching the specified strapping force, the strapping belt will not slide relative to the bundle, thereby keeping the side shift slide plate 1305 in a side shift state.

[0044] If the friction buckle fails, the tension of the strapping belt on the bundle disappears, and the side shift slide plate 1301 is reset under the action of the side shift reset spring, and the side shift detection switch detects the side shift swing rod 1305, and there is a side shift signal;

[0045] On the contrary, if the tension of the strapping belt on the bundled object is maintained, the side shift slide plate 1301 cannot be reset under the action of the side shift reset spring, and the side shift detection switch cannot detect the side shift swing rod 1305, and there is no side shift signal. The control system determines whether the friction buckle is successful by whether there is a side shift signal at this time. The automation degree is high, and the operation is very convenient and easy to use.

[0046] It should be further explained that the control system is a prior art and is not the object of protection of the present utility model, so there is no need to elaborate on it in detail.

[0047] Working principle: When the utility model is used, the strapping belt passes through the lateral displacement judgment component 13 and enters the belt inlet on the upper part of the belt feeding chain disk 2. The strapping belt can enter the chain disk limiting channel 3 between the belt feeding chain disk 2 and the outer conveying chain 4 through the belt inlet on the upper part of the belt feeding chain disk 2. The limiting channel set in the chain disk limiting channel 3 can effectively limit the two sides of the strapping belt, effectively preventing the strapping belt from falling off the belt feeding chain disk 2, improving the stability and safety of the belt feeding, and having a better use effect;

[0048] At this time, the belt feeding motor 6 is arranged to rotate, and when the belt feeding motor 6 rotates, the belt feeding chain disc 2 is driven to rotate, so that the strapping belt can be tensioned and conveyed through the rotation of the belt feeding chain disc 2. After rotating a certain angle, the strapping belt can be conveyed from the top end to the belt feeding channel 7 at the tail end;

[0049] During the continuous rotation of the belt feeding motor 6, the strapping belt in the belt feeding channel 7 will enter the channel between the bottom plate 10 and the friction buckle assembly 11;

[0050] At this time, the left and right knife pressing assemblies are set to work, and the knife pressing cylinder 801 of the knife pressing assembly can be extended. When the knife pressing cylinder 801 is extended, the connection seat 802 at the top thereof will be raised, and at the same time, the knife pressing rod 803 will be raised synchronously with the connection seat 802, and the other end of the knife pressing rod 803 will be relatively lowered, and the lowered end of the knife pressing rod 803 drives the knife pressing head 804 to descend, so that the strapping belt on the bottom plate 10 is pressed by the descending of the knife pressing head 804;

[0051] After the left and right pressure knife assemblies have pressed and fixed the strapping belt, the friction buckle assembly 11 is set to work at this time, and the pneumatic rod 1102 is driven to extend by the set driving cylinder 1101, so that the friction pressure knife 1103 is driven to descend by the extension of the pneumatic rod 1102. After the friction pressure knife 1103 descends, the strapping belt is first cut by the cutting knife. After cutting, the friction pressure knife 1103 is pressed down and contacted with the strapping belt on the bottom plate 10, and friction welding and buckling work are performed, thereby completing the strapping, cutting and buckling processing of the strapping and packaging mechanism.

[0052] The utility model is provided with an outer conveying chain 4 outside the belt conveying chain plate 2, and the driving roller 5 of the outer conveying chain 4 can press and convey the outer wall of the strapping belt, thereby effectively preventing the belt body from slipping, improving the efficiency of belt feeding, and the driving roller 5 can self-rotate by relying on the friction generated by the conveying when the strapping belt is conveyed, and can effectively reduce the friction effect of the belt feeding through the contact mode of rolling conveying, increase the smoothness of the strapping belt during conveying, reduce the resistance, and have a better belt feeding effect;

[0053] The utility model replaces the multi-gear belt feeding structure of the existing strapping mechanism with an independent chain plate rotating belt feeding structure, thereby effectively avoiding the situation that the belt is stuck during the steering process due to too many gears. The chain plate rotates from top to bottom to convey, which can effectively improve the smoothness during steering and avoid the strapping belt from getting stuck during steering, thereby avoiding the situation that the strapping belt is cut and replaced after getting stuck, thereby improving the utilization efficiency of materials, avoiding material waste, and effectively improving the overall strapping efficiency of the strapping machine, which is more practical.

[0054] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
