[0038] It should be noted that: Similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0039] According to an embodiment of the present application, a spacing adjustment mechanism is provided. The spacing adjustment mechanism is applied to a conveying mechanism 3 and includes a driving device 1 and an adjusting device 2. The driving device 1 is in transmission connection with the adjusting device 2. The adjusting device 2 is provided on two opposite sides of the conveying mechanism 3, and the two adjusting devices 2 are symmetrically arranged along the conveying direction of the conveying mechanism 3. The adjusting device 2 includes a mounting frame 21 and a jacking assembly 22. The jacking assembly 22 is rotatably arranged on the mounting frame 21. The axial direction of the jacking assembly 22 is perpendicular to the conveying direction of the conveying mechanism 3, and the driving direction of the jacking assembly 22 is the same as the conveying direction of the conveying mechanism 3. Among them, the conveying speed of the conveying mechanism 3 is greater than the driving speed of the adjusting device 2.

[0040] As Figures 1 to 9 shown, the conveying mechanism 3 is belt conveying. The spacing adjustment device 2 is provided on two opposite sides of the conveyor belt. The two spacing adjustment devices 2 are symmetrically arranged. The product passes through the spacing adjustment devices 2 through the conveyor belt. When passing through the spacing adjustment devices 2, the spacing between adjacent products is adjusted by the spacing adjustment devices 2, so as to facilitate operations such as inkjet coding and barcode scanning of the products in subsequent processes, and prevent the situation of missed inkjet and missed scanning caused by too small spacing between adjacent products.

[0041] The spacing adjustment device 2 includes a driving device 1. The driving device 1 is in transmission connection with the adjusting device 2. The driving device 1 provides power for the adjusting device 2 to drive the adjusting device 2 to adjust the spacing between adjacent products.

[0042] The driving speeds of the two symmetrically arranged adjusting devices 2 are the same. One driving device 1 can be used to drive the two adjusting devices 2; two driving devices 1 can also be used to drive respectively. In this case, the two driving devices 1 are synchronously driven to ensure that the two symmetrically arranged adjusting devices 2 can be synchronously driven, so that the products will not be skewed or misaligned during the adjustment process.

[0043] The adjusting device 2 includes a mounting frame 21 and a jacking assembly 22. The jacking assembly 22 is arranged on the top of the mounting frame 21.

[0044] The mounting frame 21 is in the shape of a rectangular plate. One mounting frame 21 is provided on each of the two opposite sides of the conveyor belt. The jacking assembly 22 is provided on both mounting frames 21, and the jacking assemblies 22 on the two mounting frames 21 are symmetrically arranged.

[0045] For example, a driving device 1 is arranged at the bottom of the mounting bracket 21. The driving device 1 is a rotary motor. A driving wheel 12 is vertically arranged on the mounting bracket 21, that is, the axial direction of the driving wheel 12 is perpendicular to the plane where the mounting bracket 21 is located. The rotating end of the rotary motor passes through the mounting bracket 21, and the driving wheel 12 is arranged at the rotating end of the rotary motor. The holding assembly 22 is a transmission roller 222. The axial direction of the transmission roller 222 is the same as the axial direction of the driving wheel 12, and both the transmission roller 222 and the driving wheel 12 are rotatably arranged on the mounting bracket 21. The transmission roller 222 is arranged on one side of the mounting bracket 21 close to the conveyor belt, and two symmetrically arranged transmission rollers 222 on opposite sides of the conveyor belt are arranged opposite to each other. A conveyor belt is sleeved on the transmission roller 222 and the driving wheel 12, and the driving wheel 12 and the transmission roller 222 are drivingly connected through the conveyor belt.

[0046] Products (such as boxed milk) are conveyed through the conveyor belt. When the products are conveyed between the two transmission rollers 222, in the state where the rotary motor is started, the driving wheel 12 drives the transmission roller 222 to rotate through the conveyor belt. The two transmission rollers 222 abut against the opposite sides of the product, and the product is clamped and driven to be conveyed along the conveying direction by the two oppositely arranged transmission rollers 222. The two symmetrically arranged transmission rollers 222 have the same rotation speed and opposite rotation directions. The product is clamped by the two transmission rollers 222 and conveyed over a short distance to adjust the distance between adjacent products, preventing the distance between adjacent products from being too small, resulting in situations such as missed spraying and missed scanning.

[0047] Certainly, in the embodiment of the present application, the driving device 1 is not limited to the above structure, and those skilled in the art can set it according to actual needs.

[0048] In the embodiment of the present application, adjusting devices are symmetrically arranged on opposite sides of the conveying mechanism. The holding assemblies of the adjusting devices are rotatably arranged on the mounting bracket, and the driving device drives the holding assemblies to rotate so that the two symmetrically arranged holding assemblies can clamp and convey the products, thereby adjusting the distance between adjacent products and avoiding situations such as missed spraying and missed scanning when performing operations such as inkjet coding and barcode scanning on the products in subsequent processes.

[0049] In one example, the holding assembly 22 includes a transmission roller 222. The transmission rollers 222 are all rotatably arranged on the mounting bracket 21. The axial direction of the transmission roller 222 is perpendicular to the conveying direction of the conveying mechanism 3. The driving device 1 drives the transmission roller 222 to rotate; wherein, a plurality of the transmission rollers 222 are arranged along the conveying direction.

[0050] Such as Figures 1 to 4 、 Figures 7 to 8As shown, the holding component 22 further includes a support roller 221. Both the support roller 221 and the drive roller 222 are cylindrical structures. The support roller 221 and the drive roller 222 are both vertically placed on the mounting frame 21, and both the support roller 221 and the drive roller 222 can rotate about their own axes.

[0051] On one side of the mounting frame 21 close to the conveying mechanism 3, two support rollers 221 are provided. The two support rollers 221 are arranged along the conveying direction of the conveyor belt. The drive roller 222 is arranged between the two support rollers 221. The diameter of the support roller 221 is larger than that of the drive roller 222. The driving device 1, the support roller 221 and the drive roller 222 are in transmission connection.

[0052] For example, the driving wheel 12, the support roller 221 and the drive roller 222 are all cylindrical structures, and the driving wheel 12, the support roller 221 and the drive roller 222 are arranged in parallel. As Figure 9 shown, the driving wheel 12, the support roller 221 and the drive roller 222 all have tooth grooves along the axial direction on their outer walls, and the driving wheel 12, the support roller 221 and the drive roller 222 are meshed and driven in sequence. The driving wheel 12 is arranged at the rotating end of the rotating motor. The driving wheel 12 is driven to rotate by the rotating motor, so that the support roller 221 meshed with the driving wheel 12 rotates, and then drives the drive roller 222 meshed with the support roller 221 to rotate.

[0053] In a state where the conveying speed of the conveyor belt is greater than the rotating speed of the drive roller 222, the drive rollers 222 symmetrically arranged on opposite sides of the conveying mechanism 3 form a pitch adjustment area. When the product moves to the drive roller 222 through the conveying device, the outer circumferential surfaces of the drive rollers 222 symmetrically arranged on both sides of the conveying mechanism 3 contact the opposite sides of the product. By contacting the opposite sides of the product with the opposite sides of the drive rollers 222, the product moves at the driving speed of the drive roller 222, so that the pitch between adjacent products is enlarged, facilitating subsequent operations such as inkjet coding and barcode scanning of the products.

[0054] By arranging a plurality of drive rollers 222 on one side of the mounting frame 21 close to the conveyor belt, and arranging the plurality of drive rollers 222 in sequence along the conveying direction, the pitch adjustment area on the conveyor belt is extended. While realizing the pitch adjustment of adjacent products, it can also play a role in guiding the products, preventing the products from being skewed or misaligned due to jolting or other reasons during the conveying process through the conveying device, which may increase the difficulty of subsequent inkjet coding and barcode scanning.

[0055] Certainly, in the embodiment of the present application, the driving device 1 and the adjusting device 2 are not limited to the above structures, and those skilled in the art can set them according to actual needs. For example, the driving device 1 can also provide power for the adjusting device 2 through a conveyor belt or other means.

[0056] In one example, the holding assembly 22 further includes a moving frame 223. The moving frame 223 is disposed on the mounting frame 21. The driving roller 222 is rotatably disposed on the moving frame 223, and the moving frame 223 is capable of moving on the mounting frame 21. Wherein, the moving frames 223 symmetrically disposed on two opposite sides of the conveying mechanism 3 can approach and move away from each other.

[0057] As Figures 1 to 3 , Figure 7 and Figure 8 shown, the holding assembly 22 further includes a moving frame 223. The moving frame 223 is in the shape of a rectangular plate. The moving frame 223 is disposed on the mounting frame 21, and the moving frame 223 is capable of moving on the mounting frame 21 to approach and move away from the conveying mechanism 3.

[0058] Both the supporting roller 221 and the driving roller 222 are rotatably disposed on the moving frame 223, and both the supporting roller 221 and the driving roller 222 can rotate on the moving frame 223 with their own axes as the centers.

[0059] The moving frame 223 is provided with a first adjustment hole. The mounting frame 21 is provided with a second adjustment hole corresponding to the first adjustment hole, and a scale line is disposed on one side of the mounting frame 21 where the second adjustment hole is located.

[0060] When it is necessary to adjust the distance between the holding assemblies 22 on two opposite sides of the conveying mechanism 3, the moving frame 223 is moved closer to and away from the conveying mechanism 3 to adjust the distance between the symmetrically disposed holding assemblies 22. After the position is adjusted, screws are passed through the first adjustment hole and the second adjustment hole to fix the position of the moving frame 223 on the mounting frame 21, preventing the moving frame 223 from moving on the mounting frame 21 during use, resulting in unstable distance between the holding assemblies 22 and affecting the use effect.

[0061] In one example, the driving device 1 includes a driving member 11, a driving wheel 12 and a conveyor belt 13. The driving wheel 12 is rotatably disposed on the mounting frame 21. The rotating end of the driving member 11 is connected to the driving wheel 12. The conveyor belt 13 is sleeved on the driving wheel 12 and the holding assembly 22.

[0062] As Figures 1 to 4 , Figure 7 and Figure 8 shown, the driving device 1 includes a driving member 11, a driving wheel 12 and a conveyor belt 13. The driving member 11 is a rotating motor. The driving wheel 12 is disposed at the rotating end of the rotating motor. The driving motor is disposed at the bottom of the mounting frame 21. The driving wheel 12 is vertically disposed on the mounting frame 21, and the rotating end of the rotating motor passes through the mounting frame 21 and is connected to the driving wheel 12. In the state where the rotating motor is started, the driving wheel 12 can rotate with its own axis as the center.

[0063] The outer walls of the driving wheel 12, the supporting rollers 221, and the driving rollers 222 are respectively in contact with the inner wall of the conveyor belt 13. The driving wheel 12 is columnar, and the conveyor belt 13 is in meshing transmission with the driving wheel 12. Two supporting rollers 221 are arranged along the conveying direction of the conveying mechanism 3, and the conveyor belt 13 is sleeved outside the two supporting rollers 221 and the driving wheel 12. When the driving wheel 12 rotates, the conveyor belt 13 moves, and the conveying direction of the conveyor belt 13 is the same as the conveying direction of the conveying mechanism 3. In this state, the supporting rollers 221 can support the conveyor belt 13, so that the part of the conveyor belt 13 close to the conveying mechanism 3 is parallel to the conveying direction of the conveying mechanism 3, so as to facilitate contacting the opposite sides of the product through the conveyor belts 13 symmetrically arranged on both sides of the conveying mechanism 3 and clamping and conveying the product.

[0064] Moreover, by arranging a plurality of driving rollers 222 between the two supporting rollers 221 arranged along the conveying direction on one side of the conveying mechanism 3, adjusting the moving frame 223 to make the driving rollers 222 approach and move away from the conveying mechanism 3, so as to hold the conveyor belt 13 by the driving rollers 222, so that the spacing adjustment mechanism can adapt to products of different sizes.

[0065] A plurality of driving rollers 222 are arranged in sequence along the conveying direction, which can not only keep the side of the conveyor belt 13 close to the conveying mechanism 3 parallel to the conveying direction, but also effectively extend the spacing adjustment area of the spacing adjustment mechanism. While adjusting the spacing between adjacent products, it can guide the products to prevent the products from being skewed when entering the next process due to the bumps of the conveyor belt of the conveying mechanism 3, resulting in situations such as product omission in processes such as inkjet coding and barcode scanning.

[0066] In one example, the adjusting device 2 further includes an adjusting component 23, the adjusting component 23 is arranged on the mounting frame 21, the adjusting component 23 abuts against the first side and / or the second side of the conveyor belt 13, and the adjusting component 23 adjusts the tension of the conveyor belt 13.

[0067] Such as Figure 1 、 Figure 2 、 Figure 7 And Figure 8 As shown, the adjusting device 2 is arranged on the mounting frame 21 and is connected to the conveyor belt 13 to adjust the tension of the conveyor belt 13 through the adjusting device 2.

[0068] For example, as Figure 7 And Figure 8 As shown, a third adjusting hole is opened on the mounting frame 21. The third adjusting hole is an oblong hole, and the third adjusting hole extends along the diagonal of the rectangular mounting frame 21. The adjusting device 2 is a rotating wheel, the rotating wheel is columnar, and the axial direction of the rotating wheel is parallel to the axial direction of the driving wheel 12.

[0069] Such as Figure 1 、Figure 2 , Figure 7 and Figure 8 As shown in Figure 7 , Figure 8 , the drive wheel 12, the rotating wheel, and the two support rollers 221 are respectively close to the corners of the rectangular mounting frame 21, and the two support rollers 221 are arranged along the conveying direction. A plurality of transmission rollers 222 are arranged between the two support rollers 221, and the plurality of transmission rollers 222 are arranged in sequence along the conveying direction.

[0070] The transmission belt 13 is sleeved outside the drive wheel 12, the rotating wheel, the support roller 221, and the transmission roller 222. The drive wheel 12 is driven to rotate by a rotating motor. The drive wheel 12 is in meshing transmission with the conveyor belt 13, so that the conveyor belt 13 moves. The rotating wheel, the support roller 221, and the transmission roller 222 are all rotatably arranged to reduce the conveying resistance of the conveyor belt 13.

[0071] The part of the conveyor belt 13 close to the conveying mechanism 3 is parallel to the conveying direction through the support roller 221, so that the conveyor belts 13 symmetrically arranged on both sides of the conveying mechanism 3 are in contact with the opposite sides of the product on the conveying mechanism 3, and the product is clamped and conveyed by the conveyor belts 13, thereby realizing the adjustment of the distance between adjacent products.

[0072] By adjusting the position of the moving frame 223 on the mounting frame 21, the transmission roller 222 is moved closer to and farther away from the conveying mechanism 3 to adapt to products of different sizes and improve the adaptability of the distance adjustment mechanism.

[0073] When the moving frame 223 can be adjusted, the tightness of the conveyor belt 13 needs to be adjusted. When the moving frames 223 on the opposite sides of the conveying mechanism 3 are close to each other, the conveyor belt 13 needs to be loosened. Adjust the position of the rotating wheel in the third adjustment hole to move the rotating wheel in the direction close to the conveying mechanism 3, and the loosening of the conveyor belt 13 can be realized; when the moving frames 223 on the opposite sides of the conveying mechanism 3 are far away from each other, the conveyor belt 13 needs to be tensioned. Adjust the position of the rotating wheel in the third adjustment hole to move the rotating wheel in the direction away from the conveying mechanism 3, and the tensioning of the conveyor belt 13 can be realized.

[0074] Of course, in the embodiment of the present application, the adjustment assembly 23 is not limited to the above structure, and those skilled in the art can set it according to actual needs.

[0075] In an example, the adjustment assembly 23 includes a turntable, a first adjustment roller, and a second adjustment roller. The turntable is rotatably arranged on the mounting frame 21. The first adjustment roller and the second adjustment roller are arranged in parallel on the turntable, and the axial directions of the first adjustment roller and the second adjustment roller are both perpendicular to the plane where the turntable is located.

[0076] Such as Figure 1As shown, the adjusting assembly 23 includes a turntable rotatably arranged on the mounting bracket 21. Both the first adjusting roller and the second adjusting roller are cylindrical structures. The first adjusting roller and the second adjusting roller are arranged in parallel on the turntable, and the axial directions of the turntable, the first adjusting roller and the second adjusting roller are the same as the axial direction of the driving wheel 12.

[0077] A gap is provided between the first adjusting roller and the second adjusting roller, and the conveyor belt 13 passes through this gap. That is to say, the outer circumferential section of the first adjusting roller contacts the inner wall of the conveyor belt 13, and the outer circumferential section of the second adjusting roller contacts the outer wall of the conveyor belt 13.

[0078] Certainly, in the embodiment of the present application, the adjusting assembly 23 is not limited to the above structure, and those skilled in the art can set it according to actual needs. For example, the outer circumferential section of the second adjusting roller contacts the inner wall of the conveyor belt 13, and the outer circumferential section of the first adjusting roller contacts the outer wall of the conveyor belt 13.

[0079] The turntable is provided with a first arc-shaped through hole, and a second arc-shaped through hole is provided on the mounting bracket 21 at a position corresponding to the first arc-shaped through hole. When it is necessary to adjust the tension of the conveyor belt 13, rotate the turntable around the axis of the turntable. For example, rotate it clockwise to make the first adjusting roller and the second adjusting roller rotate with the turntable to realize position adjustment, so as to increase the contact area between the conveyor belt 13 and the first adjusting roller and the second adjusting roller, extend the conveying path of the conveyor belt 13, and thus realize the tension adjustment of the conveyor belt 13; after adjusting to the required position, pass fasteners such as screws through the first arc-shaped through hole and the second arc-shaped through hole to fix the turntable to the mounting bracket 21 to prevent the turntable from rotating during the use of this pitch adjusting mechanism, which affects the use effect of the mechanism.

[0080] When it is necessary to loosen the conveyor belt 13, rotate the turntable in the opposite direction. For example, rotate the turntable counterclockwise to realize the loosening of the conveyor belt 13.

[0081] Certainly, in the embodiment of the present application, the rotation direction of the turntable is not limited to the above, and those skilled in the art can set it according to actual needs. For example, the turntable can also be rotated counterclockwise to tension the conveyor belt 13 and rotated clockwise to loosen the conveyor belt 13.

[0082] In one example, the driving device 1 further includes a transmission part 14 and a support frame 15. The driving member 11 and the transmission part 14 are arranged on the support frame 15. The driving member 11 is in transmission connection with the driving wheel 12 through the transmission part 14. The transmission part 14 includes a driving wheel 141, a driven wheel 142, a transmission wheel 143 and a transmission member 144. The driving wheel 141 is arranged at the rotating end of the driving member 11. The driven wheel 142 is rotatably arranged at one end of the support frame 15 far away from the driving wheel 141. The transmission member 144 is sleeved on the driving wheel 141 and the driven wheel 142. The outer circumference of the transmission wheel 143 is in transmission cooperation with the transmission member 144. Transmission rods 121 are arranged on both opposite sides of the conveying mechanism 3 symmetrically. One of the transmission rods 121 is connected to the transmission wheel 143, and the other transmission rod 121 is connected to the driving wheel 141.

[0083] As Figures 2 to 4 shown, the support frame 15 is in the shape of a rectangular plate and is arranged below the mounting frame 21.

[0084] The driving member 11 is a rotating motor. The rotating motor is arranged at the bottom of the support frame 15, and the rotating end of the rotating motor passes upward through the support frame 15. The transmission part 14 is arranged on the support frame 15 and is connected to the rotating end of the rotating motor.

[0085] The transmission part 14 includes a driving wheel 141, a driven wheel 142 and a transmission member 144. The rotating end of the rotating motor passes through one end of the rectangular support frame 15, and the driven wheel 142 is rotatably arranged at one end of the support frame 15 far away from the driving wheel 141. The transmission member 144 is a transmission chain. The transmission chain is sleeved on the driving wheel 141 and the driven wheel 142. When the rotating motor drives the driving wheel 141 to rotate, the transmission chain moves.

[0086] The transmission part 14 further includes a transmission wheel 143 and a transmission rod 121. Driving wheels 12 are symmetrically arranged on the opposite sides of the conveying mechanism 3 along the conveying direction. Transmission rods 121 are connected to the bottoms of both driving wheels 12. The top of the transmission rod 121 is connected to the driving wheel 12, and the bottom of the transmission rod 121 passes through the mounting frame 21 and is connected to the transmission part 14.

[0087] The bottom of one of the transmission rods 121 is connected to the driving wheel 141, and the bottom of the other transmission rod 121 is connected to a transmission wheel 143. The outer circumferential tangent plane of the transmission wheel 143 contacts the outer wall of the transmission chain.

[0088] The rotating motor drives the driving wheel 141 to rotate, and the transmission rod 121 connected to the driving wheel 141 drives the driving wheel 12 to rotate. At the same time, when the conveying chain is in motion, the transmission wheel 143 rotates through the transmission chain, thereby driving the transmission rod 121 to rotate, thereby causing the other driving wheel 12 to rotate. Through the transmission part 14, the driving wheels 12 on the opposite sides of the conveying mechanism 3 rotate synchronously, avoiding the conveyor belts 13 on the opposite sides of the conveying mechanism 3 from being out of sync, causing the products on the conveyor belts to be skewed, etc.

[0089] Of course, in the embodiment of the present application, the transmission part 14 is not limited to the above structure, and those skilled in the art can configure it according to actual needs. For example, one of the transmission rods 121 can be connected to the driving wheel 141, and the other transmission rod 121 can be connected to the driven wheel 142; or, two rotating motors can be used to drive the two driving wheels 12, and the two rotating motors have the same rotation speed and opposite rotation directions.

[0090] According to another embodiment of the present application, a conveying device is provided. The conveying device includes the conveying mechanism 3 and the spacing adjustment mechanism as described above.

[0091] like Figures 1 to 3 As shown, the spacing adjustment mechanism is suitable for a conveying device. The conveying device comprises a conveying mechanism 3, a conveying belt of the conveying mechanism 3 conveys products from left to right, and the spacing adjustment mechanisms are symmetrically arranged on both sides of the conveying belt.

[0092] The driving device 1 of the spacing adjustment mechanism drives the adjustment device 2 to hold and convey the product. It plays a role in adjusting the spacing between adjacent products, preventing the occurrence of missed spraying and missed scanning during the subsequent coding and scanning processes. In addition, by arranging multiple transmission rollers 222 along the conveying direction of the conveyor belt, the adjustment area of the spacing adjustment mechanism can be extended. While playing a role in adjusting the spacing between adjacent products, it can also guide the product transportation, preventing the product from being skewed due to the bumps of the conveyor belt and other reasons, which affects the coding of the product.

[0093] Moreover, by clamping the product through the spacing adjustment mechanism, it is also possible to prevent the product from tilting due to strong winds when the product is subjected to operations such as air showering, thereby enhancing the stability of the product on the conveyor belt.

[0094] In one example, the conveying mechanism 3 is provided with a guiding device 4 , and the guiding device 4 is arranged at the output end of the spacing adjustment mechanism. The guiding direction of the guiding device 4 is the same as the conveying direction of the conveying mechanism 3 .

[0095] like Figures 1 to 3 , Figures 5 to 6As shown, a guiding device 4 is further provided on the conveying mechanism 3 to adjust the placement angle of the products through the guiding device 4, so as to avoid the products being skewed during processes such as inkjet coding and barcode scanning, which may lead to failures in inkjet coding and barcode scanning, such as missed inkjet and missed scan.

[0096] The spacing adjustment mechanism has an output end, and the input end of the guiding device 4 is close to the output end of the spacing adjustment mechanism. That is to say, after the spacing adjustment mechanism adjusts the spacing between adjacent products, the products enter the guiding area of the guiding device 4, and the guiding device 4 adjusts the placement angle of the products, so as to facilitate spraying on the products during inkjet coding and also avoid situations such as missed scanning in subsequent barcode scanning processes.

[0097] In one example, the guiding device 4 includes a first adjustment part 41, a second adjustment part 42, and a locking part 43; the first adjustment part 41 is arranged on opposite sides of the conveying mechanism 3 along the conveying direction, and the first adjustment part 41 has a first connection hole 411; the second adjustment part 42 includes a connecting part 421 and a guiding part 422, the connecting part 421 has a second connection hole 4211, at least part of the second connection hole 4211 corresponds to the first connection hole 411, one end of the connecting part 421 close to the conveying mechanism 3 is connected to the guiding part 422, the input end of the guiding part 422 has a bending part 4221, and the spacing between the bending parts 4221 of the two oppositely arranged guiding parts 422 gradually decreases along the conveying direction; one end of the locking part 43 sequentially passes through the second connection hole 4211 and the first connection hole 411.

[0098] As Figure 1 、 Figure 2 、 Figure 5 and Figure 6 As shown, the first adjustment parts 41 are symmetrically arranged on opposite sides of the conveying mechanism 3. The first adjustment part 41 has a longitudinal section and a transverse section. The longitudinal section is fixed to the side wall of the conveying mechanism 3 by screws, and the transverse section has a first connection hole 411, and the first connection hole 411 is an oval hole.

[0099] The second adjustment part 42 includes a connecting part 421 and a guiding part 422. The connecting part 421 and the guiding part 422 are connected by means such as bonding, welding, or integral molding. A second connection hole 4211 is provided on the connecting part 421, and the second connection hole 4211 is an oval hole. Screws are passed through the second connection hole 4211 and the first connection hole 411 to connect the connecting part 421 and the first adjustment part 41. By adjusting the position of the second adjustment hole on the connecting part 421 corresponding to the first adjustment hole, the position adjustment of the guiding part 422 is realized.

[0100] The guiding member 422 has a bent portion 4221. The guiding members 422 are symmetrically arranged on the opposite sides of the conveying mechanism 3 along the conveying direction. The two guiding members 422 form a flared input end. By providing the flared input end, when the products are placed at different angles, they can smoothly enter the guiding area. Through the flared input end, the placement angles of the products are gradually adjusted, and finally they are conveyed along the guiding direction of the guiding area, so that the products can be neatly placed when they reach the coding device 5, facilitating operations such as inkjet coding of the products by the coding device 5.

[0101] Of course, in the embodiment of the present application, the guiding device 4 is not limited to the above structure, and those skilled in the art can set it according to actual needs.

[0102] In one example, a coding device 5 is arranged on one side of the conveying mechanism 3, and the position of the coding device 5 corresponds to that of the guiding device 4.

[0103] Such as Figure 1 and Figure 3 As shown, the coding device 5 includes a nozzle and a monitoring device. The coding device 5 is placed on one side of the conveying mechanism 3 and is located on the side of the guiding device 4 away from the spacing adjustment mechanism.

[0104] The nozzle is arranged above the side of the guiding device 4 away from the spacing adjustment mechanism. When the product is in the guiding area and being output, the monitoring device scans the approaching product. When the monitoring device scans that the product moves below the nozzle, the nozzle is activated to perform operations such as inkjet coding on the product.

[0105] Of course, in the embodiment of the present application, the conveying mechanism 3 is not limited to the above structure, and those skilled in the art can set it according to actual needs. For example, since the spacing adjustment mechanism has a guiding function, the above-mentioned guiding device 4 can be not provided. At this time, the coding device 5 is placed at the output end of the spacing adjustment mechanism. When the monitoring device scans that the product is conveyed below the nozzle, the nozzle is activated to perform operations such as inkjet coding on the product.

[0106] Although some specific embodiments of the present application have been described in detail by way of examples, those skilled in the art should understand that the above examples are only for illustration and not for limiting the scope of the present application. Those skilled in the art should understand that the above embodiments can be modified without departing from the scope and spirit of the present application. The scope of the present application is defined by the appended claims.
