The discharging guide rail is fixed in the slot hole through the connecting block, the limiting edges connected to the two discharging side plates form a limiting gap between the discharging guide rail, the strap drawn out of the feeding hole passes through the top side of the discharging guide rail, and the limiting gap formed by the two discharging limiting edges limits the two sides of the strap, so as to limit the strap from directly entering the hole when being sent out. The strap is wound around the guide belt support for one turn and then enters between the discharging limiting edge and the limiting edge. When the strap needs to be used for packaging articles, the external device will compress the part of the strap sent out from between the discharging limiting edge and the limiting edge, and then the driving wheel is reversed to wind the strap. During the winding process, the strap passes through the two discharging limiting edges, at this time, the two discharging side plates are spring-pressed away from each other, so that the two first springs are elastically compressed. When the strap is separated from the discharging limiting edge, the elastic force of the two first springs restores the two first pressing columns to be pushed into the discharging guide rail, and the discharging side plate is returned to the reset position through the first pressing block.

The belt moves along the inner side of the material guiding bracket, and when passing through the material guiding assembly, the front and rear directions of the belt are limited by the material guiding side plates on the front and rear sides, and the material guiding side plates limit the belt from directly falling into the hole. When the belt is wound to package the articles, the belt needs to pass through the two material guiding side plates, at which time the two material guiding side plates are spring away from each other, so that the two second springs are elastically compressed. When the belt is separated from the material guiding side plates, the elastic force of the two second springs pushes the two second pressing columns into the material guiding bracket, and the material guiding side plates are driven back to the reset position by the second pressing block.

[0010] As a further improvement of the above technical solution, the material guiding side plates are inclined away from the center of the hole in the outfeed direction.

DETAILED DESCRIPTION

[0023] The concept, specific structure and generated technical effects of the present application will be clearly and completely described below by combining with the embodiments and drawings, so as to fully understand the purpose, features and effects of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all embodiments, and the person skilled in the art can obtain other embodiments without creative labor based on the embodiments of the present application, which all belong to the scope of protection of the present application.

The technical features in the present application can be combined interactively without mutual contradiction and conflict.

[0024] Reference Figure 1A kind of belt feeding mechanism, including: the bottom side of platform 1 is provided with slot hole extending along left and right direction, the one side of platform 1 is provided with the feed hole being communicated with the slot hole;Material roll assembly is located in the one side of platform 1 close to the feed hole, and the material roll assembly has driving wheel 2 that can be wound or unwound in it;Guide belt support 3 is connected to the top side of platform 1, and the hole 31 is formed around between guide belt support 3 and platform 1;Discharge assembly is arranged in the slot hole, and the discharge assembly is spaced apart in front and back direction and is provided with two discharge side plates 41 in it, and the side of the two discharge side plates 41 opposite each other is respectively connected with discharge baffle 42, and the discharge assembly has first elastic member that can drive the two discharge side plates 41 to approach each other in it;Material guide assembly is spaced apart in front and back direction and is provided with two material guide side plates 51, and the side of the two material guide side plates 51 opposite each other is respectively connected with material guide baffle 52, and the material guide assembly has second elastic member 54 that can drive the two material guide side plates 51 to approach each other in it, and the material guide assembly is provided with multiple around the hole 31 in the inner side of guide belt support 3.

[0025] In the belt feeding mechanism, driving wheel 2 can be loaded with a belt roll for packaging, driving wheel 2 unwinds, and the unwound belt is fed from the belt roll to the discharge assembly through the feed hole on one side of the platform 1. At this time, the belt is located between the two discharge side plates 41, and the discharge side plates 41 are shielded on the side of the belt close to the hole 31 by the discharge baffle 42, so that the belt does not enter the hole 31 during unwinding. The belt is continuously fed along the inner side of the guide belt support 3, and the multiple material guide assemblies provided on the guide belt support 3 can ensure that the belt is fed around the hole 31. The two material guide side plates 51 in the material guide assembly play a front and back limiting role, and the belt is limited by the material guide baffle 52 on the two material guide side plates 51, preventing the belt fed along the inner side of the guide belt support 3 from falling into the hole 31. The article to be packaged is placed in the hole 31, and when the article needs to be packaged, the driving wheel 2 is reversed to wind up, and the belt moves towards the hole 31. During this process, the belt abuts against the discharge baffle 42 and the material guide baffle 52, and as the winding force of the belt gradually increases, the two discharge side plates 41 and the two material guide side plates 51 opposite each other are pushed apart to the front and back sides, so that the belt passes over the discharge baffle 42 and the material guide baffle 52, and is wound around the outside of the article. The discharge side plates 41 and the material guide side plates 51 are elastically reset after losing external force to prepare for limiting the next belt feeding. This simplifies the structure of the belt limiting during feeding, reduces the required driving source, and makes the structure for feeding the belt simpler, reduces the work energy consumption during belt feeding, and reduces the overall production and maintenance costs.

[0026] The driving source in the roll assembly can drive the driving wheel 2 to rotate, for example, a driving motor is used to drive the driving wheel 2. In order to improve the stability of the belt feeding, a spring rod and a pressing wheel are installed above the driving wheel 2. The spring rod drives the pressing wheel to press against the driving wheel 2, thereby improving the stability of the belt feeding.

[0027] The first elastic member in the discharge assembly can elastically approach or move away from the two discharge side plates 41, for example, the first elastic member is made of rubber, and the two discharge side plates 41 are connected by the rubber. In the embodiment, as shown in the figure, the discharge assembly includes a discharge guide rail 43 and a first pressing column 44. The discharge guide rail 43 is located in the slot hole, and the discharge guide rail 43 and the table plate 1 are connected by a connecting block 45. The two discharge side plates 41 are located on the front and rear sides of the discharge guide rail 43. The two discharge side plates 42 are located above the discharge guide rail 43 and are provided with a limiting side 46. The two discharge side plates 42 are located above the limiting side 46. The first elastic member is a first spring. The two discharge side plates 41 are provided with the first pressing column 44. One end of the first pressing column 44 abuts against the discharge side plate 41. The other end of the first pressing column 44 penetrates into the discharge guide rail 43 and is connected with the first spring. The first spring has a tendency to push the first pressing column 44 into the discharge guide rail 43. Figure 2 The discharge guide rail 43 is fixed in the slot hole by the connecting block 45. The limiting side 46 connected to the two discharge side plates 41 forms a limiting gap between the discharge guide rail 43. The belt drawn from the feeding hole passes through the top side of the discharge guide rail 43 and is limited by the limiting gap formed by the two discharge side plates 42 on both sides of the belt, so as to limit the belt from directly entering the hole 31 when feeding. The belt is wound around the guide belt support 3 for one turn and then enters between the discharge side plate 42 and the limiting side 46. When the belt is needed to be used for packaging articles, the external device will compress the part of the belt sent from between the discharge side plate 42 and the limiting side 46, and then the driving wheel 2 is reversed to wind the belt. During the winding process, the belt passes through the two discharge side plates 42, which will spring the two discharge side plates 41 away from each other, so that the two first springs are elastically compressed. When the belt is separated from the discharge side plate 42, the elastic force of the two first springs will push the two first pressing columns 44 into the discharge guide rail 43, and the first pressing block drives the discharge side plate 41 to return to the original position.

[0028] Further, the end side of the discharge guide rail 43 close to the feeding hole is provided with a guide surface 431, which extends downwardly and obliquely towards the feeding hole. The two limiting edges 46 close to the feeding hole extend upwardly and obliquely towards the feeding hole. The oblique guide surface 431 of the discharge guide rail 43 and the oblique end of the limiting edge 46 form a guide space which gradually narrows away from the feeding hole. When the belt is sent out and enters the guide space, the belt is guided by the guide surface 431 and the oblique end of the limiting edge 46, so that the two sides of the belt can stably enter between the limiting edge 46 and the lower guide rail.

[0029] Similarly, the second elastic member 54 in the guide assembly can also be directly made of rubber, and the two guide side plates 51 are connected to each other by the rubber. In the embodiment, as shown in the figure, Figure 3 the guide assembly includes second pressing columns 53, the second elastic member 54 is a second spring, the two guide side plates 51 are respectively located on the front and rear sides of the belt support 3, the two guide side plates 51 are respectively provided with the second pressing columns 53, one end of the plurality of second pressing columns 53 is respectively abutted against the guide side plate 51, the other end of the plurality of second pressing columns 53 is respectively penetrated into the discharge guide rail 43 and connected with the second spring, and the second spring has a tendency to push the second pressing column 53 into the inside of the belt support 3. When the belt moves along the inside of the belt support 3 and passes through the guide assembly, the front and rear directions of the belt are limited by the guide side plates 51 on the front and rear sides, and the guide side plates 51 limit the belt from directly falling into the hole 31. When the belt is wound to package the articles, the belt needs to pass over the two guide side plates 51, which will make the two guide side plates 51 spring away from each other, so that the two second springs are elastically compressed. When the belt is separated from the guide side plates 52, the elastic force of the two second springs will push the two second pressing columns 53 into the inside of the belt support 3, so as to drive the guide side plates 51 to return to the original position by the second pressing columns.

[0030] In actual application, the upper side, the left side and the right side of the belt support 3 are all provided with the guide assembly. The guide assembly on each side can be provided with one, two or three, etc. according to the length of the side of the belt support 3.

[0031] Further, the guide edge 52 is arranged to be inclined away from the center of the hole 31 along the discharging direction, the discharging direction being the direction in which the strap sequentially passes through the feeding hole, the discharging assembly and rotates around the hole 31. The two guide edges 52 and the guide belt bracket 3 form a gradually reduced guide gap along the discharging direction. When the strap enters a guide assembly, the guide gap formed by the two guide assemblies and the guide belt bracket 3 is initially large, and as the strap gradually moves along the discharging direction, the gradually reduced guide gap guides the strap, which can improve the accuracy of the strap conveying and guiding, and the strap can more accurately enter the next guide assembly.

[0032] Further, the left and right sides of the guide belt bracket 3 are spaced apart in the front-rear direction and are provided with limiting side plates 32. The guide belt bracket 3 is provided with limiting side plates 32 for further front-rear limiting of the strap at the left and right positions, which effectively prevents the strap from moving forward and backward.

[0033] The utility model also includes a transition assembly, such as Figure 4 As shown in the drawings, the transition assembly includes a transition guide rail 61, a transition side plate 62 and a third pressing column 63. The transition guide rail 61 is located in the slot hole, and the transition guide rail 61 is located on the side away from the feeding hole relative to the discharging assembly. The transition guide rail 61 and the table plate 1 are connected with a fixed block 64. Two transition side plates 62 are located on the front and rear sides of the transition guide rail 61, respectively. Two transition side plates 62 are connected with a transition edge 65 at a position above the transition guide rail 61. Two third pressing columns 63 are respectively arranged in the transition side plates 62. One end of a plurality of third pressing columns 63 abuts against the transition side plate 62, respectively. The other end of a plurality of third pressing columns 63 penetrates into the transition guide rail 61 and is connected with a third spring. The third spring has a tendency to push the third pressing column 63 into the transition guide rail 61. The strap passes through the transition assembly before moving out of the discharging assembly and moving to the guide belt bracket 3. When passing through the transition assembly, the front and rear directions of the strap are limited by the transition side plates 62 on the front and rear sides, and the transition edge 65 on the transition side plate 62 limits the strap from directly falling into the hole 31. When the strap is wound to package the articles, the strap needs to pass over the two transition edges 65, which will make the two transition side plates 62 spring away from each other, so that the two third springs are elastically compressed. When the strap is separated from the transition edge 65, the elastic force of the two third springs pushes the two third pressing columns 63 into the guide belt bracket 3, and the third pressing block drives the transition side plate 62 to return to the reset position.

[0034] Further, the transition rail 61 is provided with a transition surface 611 on the top side of the end close to the feeding hole, which extends downwardly and inclines towards the direction close to the feeding hole. The inclined transition surface 611 can guide the strap feeding, so that the strap is more accurately and stably transferred to the top side of the transition rail 61, and the stability of the strap feeding is improved.

[0035] In some embodiments, the top of the strap support 3 is provided with a avoiding gap. The avoiding gap can provide a space for avoiding the execution structure of the external device, such as the device of the external device for punching the strap, so that the overall expansion function can be enriched.

[0036] A strap packaging machine comprises the strap feeding mechanism.

[0037] In the strap packaging machine, the structure for limiting the strap when feeding out is simplified by using the strap feeding mechanism, the required driving source is reduced, the structure for executing the strap feeding out is simpler, the work energy consumption during the strap feeding is reduced, and the overall production and maintenance cost is reduced.
