[0026] Example:

[0027] See also Figure 1-4A sprocket transmission device with adjustable feeding spacing includes a support frame 1 and a clutch transmission plate 2. The clutch transmission plate 2 is arranged on one side of the support frame 1. The symmetrical two side ends of the support frame 1 are fixedly connected with plug-in blocks 3. The ends away from the two plug-in blocks 3 are fixedly connected with fixed tubes 4. The circumferential surfaces of the two fixed tubes 4 are rotatably connected with a first sprocket 5 and a second sprocket 6. A first chain 7 is connected between the two first sprockets 5, and the two first sprockets 5 are meshed with the first chain 7. A second chain 8 is connected between the two second sprockets 6, and the two second sprockets 6 are meshed with the second chain 8. The first A plurality of positioning blocks 9 are fixedly connected to the chain 7, a plurality of positioning limit blocks 10 are fixedly connected to the second chain 8, and the plurality of positioning limit blocks 10 are respectively arranged in an interlaced manner with the plurality of positioning blocks 9. The output end of the clutch transmission plate 2 is fixedly connected to a polyhedral shaft 11, and the polyhedral shaft 11 movably passes through a fixed tube 4, a first sprocket 5 and a second sprocket 6. A locking assembly is provided between a first sprocket 5 and a second sprocket 6 and the polyhedral shaft 11. The locking assembly is used to fix a first sprocket 5 and a second sprocket 6, so that the polyhedral shaft 11 drives a first sprocket 5 and a second sprocket 6 to rotate.

[0028] In this embodiment, multiple positioning limit blocks 10 and multiple positioning pull blocks 9 are staggered to form multiple spaces for positioning products, and each positioning space is equidistantly distributed. When heavier products are conveyed, by placing the products in each positioning space, the clutch transmission plate 2 controls the rotation of the multi-faceted shaft 11, and the multi-faceted shaft 11 drives a first sprocket 5 and a second sprocket 6 to rotate through the locking assembly, so that the first chain 7 and the second chain 8 are respectively transmitted between the two first sprockets 5 and the two second sprockets 6. The first chain 7 and the second chain 8 respectively drive the multiple positioning pull blocks 9 and the multiple positioning limit blocks 10 to move synchronously, so that the products between the multiple positioning pull blocks 9 and the multiple positioning limit blocks 10 are moved and conveyed. When products of different sizes need to be conveyed, by canceling the connection between the locking assembly and the first sprocket 5 and the second sprocket 6, the first sprocket 5 and the second sprocket 6 can rotate on a fixed tube 4, thereby driving the first chain 7 and the second chain 8 to transmit, so that the positioning spaces between the multiple positioning pull blocks 9 and the multiple positioning limit blocks 10 are adjusted to accommodate products of different sizes.

[0029] Specifically, the locking assembly includes an anti-slip tooth block 121, a locking block 122, a locking bolt 123 and a connecting plate 124. The anti-slip tooth block 121 is slidably connected to the outer surface of the polyhedral shaft 11, the locking block 122 is fixedly connected to one end of a first sprocket 5, and the anti-slip tooth block 121 is located in the locking block 122, the locking bolt 123 is threadedly connected to the locking block 122, the connecting plate 124 is slidably connected to the outer surface of the polyhedral shaft 11, and the connecting plate 124 is detachably connected to one end of a second sprocket 6.

[0030] In this embodiment, the locking block 122 is tightened by the locking bolt 123, so that the friction between the locking block 122 and the anti-slip tooth block 121 is increased, and the polyhedral shaft 11 drives the anti-slip tooth block 121 to rotate when it rotates. The anti-slip tooth block 121 drives a first sprocket 5 to rotate through the friction with the locking block 122. By installing the connecting plate 124 on a second sprocket 6, the polyhedral shaft 11 drives the connecting plate 124 to rotate when it rotates, thereby driving a second sprocket 6 to rotate, realizing the driving of the device and conveying the product.

[0031] Specifically, a plurality of connection ports 13 are defined on the connection plate 124 , a plurality of connection holes 14 are defined on the second sprocket 6 , and the plurality of connection ports 13 correspond to the plurality of connection holes 14 , respectively.

[0032] In this embodiment, the plurality of connection ports 13 correspond to the plurality of connection holes 14 and are connected by bolts so that the connection plate 124 is installed on a second sprocket 6 , thereby driving the transmission between the two second sprockets 6 and the second chain 8 .

[0033] Specifically, two tensioning blocks 15 are slidably inserted into the bottom end of the support frame 1, and the two tensioning blocks 15 slide through the two plug-in blocks 3 respectively. The symmetrical two side ends of the two tensioning blocks 15 are rotatably connected with tensioning sprockets 16, and the four tensioning sprockets 16 are respectively engaged with the first chain 7 and the second chain 8. Two adjusting bolts 17 are movably inserted into the top of the support frame 1, and the two adjusting bolts 17 are respectively threadedly connected to the two plug-in blocks 3 corresponding to the two tensioning blocks 15.

[0034] In this embodiment, the two adjusting bolts 17 are threadedly connected to the two plug-in blocks 3, so that the bottom ends support the two tensioning blocks 15. The two tensioning blocks 15 cause the four tensioning sprockets 16 to generate a downward force to engage with the first chain 7 and the second chain 8, thereby controlling the tensioning force of the first chain 7 and the second chain 8 during transmission and ensuring the stability of the product during transportation.

[0035] Specifically, first bearings 18 are respectively provided between the two first sprockets 5 and the two second sprockets 6 and the two fixed tubes 4 , and second bearings 19 are respectively provided between the four tensioning sprockets 16 and the two first sprockets 5 .

[0036] In this embodiment, the four first bearings 18 reduce the friction between the two first sprockets 5 and the two second sprockets 6 and the two fixed tubes 4, making the rotation smoother, and the four second bearings 19 reduce the friction between the four tensioning sprockets 16 and the two tensioning blocks 15, making the rotation smoother.

[0037] Specifically, a plurality of fixing rods 20 are fixedly connected in the support frame 1 , and two ends of the plurality of fixing rods 20 respectively pass through two sides of the support frame 1 .

[0038] In this embodiment, the support frame 1 can be installed and fixed by a plurality of fixing rods 20. The number of the fixing rods 20 is set to be more than two, which can ensure that the device remains stable during the transmission and feeding process.

[0039] Working principle: When conveying the product, the contact between the inner surface of the locking block 122 and the outer surface of the anti-slip tooth block 121 is canceled by twisting the locking bolt 123, so that a first sprocket 5 can rotate on a fixed tube 4, thereby driving the first chain 7 to transmit between the two first sprockets 5, realizing the adjustment of the positions of multiple positioning blocks 9, and the spacing between the multiple positioning blocks 9 and the multiple positioning limit blocks 10 for placing products is adjusted, and the positioning space formed can adapt to the product size. At the same time, by removing the connecting plate 124 from a second sprocket 6, a second sprocket 6 can rotate on a fixed tube 4, thereby driving the second chain 8 to transmit between the two second sprockets 6, realizing the adjustment of the positions of multiple positioning limit blocks 10, and also the spacing between the multiple positioning blocks 9 and the multiple positioning limit blocks 10 for placing products, and the positioning space formed by the multiple positioning limit blocks 9 and the multiple positioning limit blocks 10. After the limit block 10 is adjusted to adapt to the product size, the locking block 122 is tightened by the locking bolt 123 to increase the friction force between the locking block 122 and the anti-slip tooth block 121, and the active first sprocket 5 is locked and fixed with the anti-slip tooth block 121. By installing the connecting plate 124 on the active second sprocket 6, the second sprocket 6 and the connecting plate 124 are fixed. The clutch transmission plate 2 controls the multi-faceted shaft 11 to start, and the multi-faceted shaft 11 drives the connecting plate 124 and the anti-slip tooth block 121 to rotate, thereby driving a first sprocket 5 and a second sprocket 6 to rotate, so that the first chain 7 and the second chain 8 are respectively transmitted between the two first sprockets 5 and the two second sprockets 6, and the first chain 7 and the second chain 8 respectively drive multiple positioning blocks 9 and multiple positioning limit blocks 10 to move synchronously, so that the products between the multiple positioning blocks 9 and the multiple positioning limit blocks 10 are moved and conveyed.

Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and improved ideas of the present invention, which should be covered by the protection scope of the present invention.
