Description

Technical Field

[0001] The present invention relates to the technical field of air conveying equipment, in particular to a single-channel air conveying machine. Background Art

[0002] In the field of automated arrangement and conveying of cylindrical cans such as cans, existing equipment generally uses wind zoning control technology to achieve posture adjustment and queue regularity of workpieces.

[0003] Traditional can pneumatic conveying equipment uses thin stainless steel channel plates. For example, patent publication number CN119637519B discloses a single-channel can pneumatic conveying system in which air holes are punched through sheet metal. This process inevitably creates bulges around the air holes, resulting in poor channel plate flatness and impacting the maximum can conveying speed.

[0004] Existing equipment usually divides the wind system into 5 or more independent wind zones. The more independent wind zones there are, the more problems such as the following will occur:

[0005] 1. Since each air zone is equipped with independent air ducts and air pressure adjustment components, the more independent air zones there are, the more components need to be added, and the higher the processing difficulty and cost of the equipment;

[0006] 2. The more wind zones there are, the easier it is for airflows to collide with each other and generate turbulence, affecting the stability of the workpiece operation;

[0007] 3. For cans of different specifications, operators need to adjust the wind pressure parameters of multiple wind zones one by one. The more wind zones there are, the longer the adjustment time will be;

[0008] 4. The more partitions you have, the greater the air duct resistance will be, which will increase the system energy consumption.

[0009] 5. The more partitions there are, the higher the risk of airflow leakage, and the equipment maintenance cost increases significantly. Summary of the Invention

[0010] The purpose of the present invention is to provide a single-channel air conveyor to solve the problems of complex structure, low adjustment efficiency, high energy consumption and maintenance costs of existing automatic can arrangement and conveying equipment, to achieve high-speed and stable operation of converting multiple channels of cans into a single channel, and to reduce the probability of can blockage.

Boxes are provided on the end faces of the two channel plates on the opposite sides, the box is installed on the frame, and an air inlet is provided on the box. A main air supply cavity is provided in the box, and the box and the channel plates together form an upper conveying cavity, a lower conveying cavity, a discharge reflux cavity and an upward floating air cavity that are independent of each other. The main air supply cavity is vented. The ventilation holes arranged through the box body are respectively connected with the upper conveying chamber, the lower conveying chamber, the discharge reflux chamber and the upper floating air chamber, and a gate assembly is provided on the box body and at each ventilation hole; the distribution area of ​​the track air holes coincides with the horizontal projections of the upper conveying chamber, the lower conveying chamber and the discharge reflux chamber, the distribution area of ​​the upper floating air holes coincides with the horizontal projections of the upper floating air chamber and the discharge reflux chamber, and the distribution area of ​​the back-blowing air holes coincides with the horizontal projection of the discharge reflux chamber; the angle between the center line of the track air holes, the upper floating air holes and the back-blowing air holes and the channel plate is a, and a is 15 to 45 degrees.

[0012] Furthermore, the distribution area of ​​the track air holes includes an upper straight segment area, an upper circular segment area, a lower circular segment area, and a lower straight segment area, which are connected in sequence. The upper straight segment area and the upper circular segment area coincide with the horizontal projection of the upper conveying chamber. The distribution area of ​​the floating air holes is adjacent to and located above the lower straight segment area. The two channel plates are each provided with a return flow guide plate on the end surface facing each other. The return flow guide plate includes an upper guide surface and a lower guide surface. The distribution area of ​​the backflow air holes is located within the area enclosed by the lower guide surface, the lower straight segment area, and the distribution area of ​​the floating air holes. The horizontal projection of the center line of the track air holes in the upper straight segment area is horizontal, the horizontal projection of the center line of the track air holes in the lower straight segment area is horizontal, and the horizontal projection of the center line of the track air holes in the upper and lower circular segments is tangent to the arc of the track in which they are located.

[0013] Furthermore, guide assemblies are provided on the end faces facing each other of the two channel plates, and the guide assemblies include a conveying guide plate and a discharge adjustment plate. The conveying guide plate is located outside the distribution area of ​​the track air holes, and the inner wall of the conveying guide plate is adapted to the U-shaped distribution track of the track air holes. The conveying guide plate includes an upper straight guide section, a semicircular reversing guide section and a lower straight guide section, and the inner side of the conveying guide plate is a U-shaped structure; the discharge adjustment plate is located between the return guide plate and the lower straight guide section, and a mounting hole is provided on the discharge adjustment plate, and the discharge adjustment plate and the channel plate are connected by bolts, and an internal threaded hole adapted to the bolt is provided on the channel plate, and the bolt is threadedly connected to the channel plate after passing through the mounting hole; when the bolt is not tightened on the discharge adjustment plate, it can move relative to the mounting hole along the length direction of the mounting hole in the mounting hole.

[0014] The conveying guide plate and the discharge adjustment plate limit and guide the cans, preventing them from deviating from the predetermined path and ensuring that they move smoothly along the upper linear guide section, the semicircular reversing guide section and the lower linear guide section.

[0015] When it is necessary to convey cans of different specifications, the discharge adjustment plate can be moved up and down to change the height of the discharge channel, thereby ensuring that cans of various sizes can be discharged smoothly through the discharge channel to meet diversified production needs.

[0016] Furthermore, it also includes a can-prying mechanism, which includes a can-prying shaft and a drive motor. The can-prying shaft is rotatably connected to the box body, and the can-prying shaft is located between the discharge adjustment plate and the distribution area of ​​the back-blowing air holes. The drive motor is installed on the box body, and the drive motor is transmission-connected to the can-prying shaft. The can-prying shaft is used to pry the contacted cans to the side away from the discharge adjustment plate, and the gap between the can-prying shaft and the lower linear guide section allows the cans to pass through in a single row.

[0017] The driving motor drives the can-pushing shaft to rotate continuously, so that the can-pushing shaft pushes the cans to the distribution area of ​​the back-blowing air holes, reducing the probability of can blockage and improving the stability and reliability of equipment operation.

[0018] Furthermore, the device further comprises a back-blowing housing fixedly connected to the channel plate, wherein the output end of the back-blowing housing blows air toward the distribution area of ​​the back-blowing holes.

The provision of the air outlet facilitates the supply of air to the back-blowing housing, and the provision of the gate assembly facilitates the adjustment of the ventilation volume of the air outlet.

[0020] Furthermore, the gate assembly includes an air adjustment frame, an air adjustment door, an air adjustment rod, and an air adjustment nut. The air adjustment frame and air adjustment nut are fixedly connected to the housing, the air adjustment rod is threadedly connected to the air adjustment nut, and the air adjustment rod is rotatably connected to the air adjustment door. The gate assembly facilitates air volume adjustment. A handle can be installed on the air adjustment rod to facilitate rotation of the air adjustment rod.

[0021] Furthermore, the horizontal projection line of the center line of the upward air hole is in a vertical state, and the horizontal projection line of the center line of the reverse air hole is in a horizontal state.

[0022] Furthermore, the two channel plates are both provided with a DLC coating on their facing end surfaces. This coating reduces the friction coefficient, prevents aluminum powder from adhering, and significantly reduces the cleaning and maintenance work of the channel plates.

[0023] Furthermore, the system includes a spacing adjustment mechanism, which comprises a movable frame, a screw lift, a transmission shaft, and a linear slide. A movable frame is mounted at each end of one of the boxes, and the screw lift is mounted on the movable frame. The two screw lifts are connected via a transmission shaft. The output end of the screw lift is connected to the frame, and the linear slide is fixed to the frame. The movable frame is connected to the slider of the linear slide.

[0024] Beneficial effects of this technical solution:

[0025] 1. The present invention reduces the number of wind zones by rationally designing the upper conveying chamber, lower conveying chamber, discharge return chamber and upper floating air chamber.

[0040] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0041] See also Figures 1 to 11 The present invention provides a single-channel air delivery unit, comprising a frame 1, a housing 2, and two channel plates 3. The channel plates 3 are symmetrically arranged, with a thickness of 8-20 mm. The channel plates 3 are provided with track air holes 31, upward air holes 32, back-blowing air holes 33, and ventilation air holes 34. The track air holes 31 are arranged in a U-shaped pattern.

[0042] Different from the prior art, the channel plate 3 of the device of the present application is manufactured by machining, which increases the thickness of the channel plate 3. The machining process ensures that the plane of the channel plate 3 has good flatness, avoids the bulging problem caused by air hole processing, and provides a good basic condition for the stable transportation of cans.

[0043] In this embodiment, a housing 2 is mounted on the opposite end faces of each of the two channel plates 3. The housing 2 is mounted on the frame 1 and is provided with an air inlet 21. A main air supply chamber 22 is provided within the housing 2. The housing 2 and the channel plates 3 together enclose an independent upper conveying chamber 23, a lower conveying chamber 24, a discharge and return chamber 25, and an upper floating air chamber 26. These chambers are each independent wind zones. Compared to existing technologies that divide wind systems into five or more independent wind zones, this device innovatively optimizes the wind zones into four zones.

[0044] It should be noted that the merging of wind zones must take into account the airflow distribution and running direction of each wind zone, as well as the stability of the tank conveying operation state. The operation state of the tank after merging the wind zones is better than when the wind zones are separated. This is the only way to better improve the conveying speed and facilitate adjustment. Therefore, the merging of wind zones cannot be done simply and arbitrarily, otherwise it may affect the stability of the tank conveying.

[0045] In this embodiment, four ventilation openings are provided on the partitions within the housing 2, corresponding to the upper conveying chamber 23, the lower conveying chamber 24, the discharge return chamber 25, and the upper floating air chamber 26. The main air supply chamber 22 communicates with the upper conveying chamber 23, the lower conveying chamber 24, the discharge return chamber 25, and the upper floating air chamber 26 through the ventilation openings provided within the housing 2. A gate assembly 4 is provided on the housing 2 at each ventilation opening. The gate assembly 4 facilitates adjustment of the ventilation volume of the ventilation openings, rationally allocating wind resources to the upper conveying chamber 23, the lower conveying chamber 24, the discharge return chamber 25, and the upper floating air chamber 26 to meet the needs of different can conveying stages.

[0046] It should be noted that the main air supply chamber 22 will flow into the upper conveying chamber 23, the lower conveying chamber 24, and the discharge reflux chamber 25 through the ventilation holes. The operator can change the opening size of the ventilation holes by adjusting the gate assembly 4 according to actual needs to control the air volume and pressure entering each cavity.

[0047] In this embodiment, the distribution area of ​​the track air hole 31 coincides with the horizontal projections of the upper conveying chamber 23, the lower conveying chamber 24, and the discharge reflux chamber 25, the distribution area of ​​the floating air hole 32 coincides with the horizontal projections of the floating air chamber 26 and the discharge reflux chamber 25, and the distribution area of ​​the back-blowing air hole 33 coincides with the horizontal projection of the discharge reflux chamber 25.

[0048] In this way, the air flow blown out of the track air hole 31 will enter the upper conveying chamber 23, the lower conveying chamber 24, and the discharge reflux chamber 25, the air flow blown out of the upper floating air hole 32 will enter the upper floating air chamber 26 and the discharge reflux chamber 25, and the air flow blown out of the back-blowing air hole 33 will enter the discharge reflux chamber 25.

[0049] In this embodiment, please refer to Figures 9 to 11 The included angle between the center line of the track air hole 31, the floating air hole 32, the back-blowing air hole 33 and the channel plate 3 is a, and a is 15 to 45 degrees.

[0050] It should be noted that the angle design of angle a enables the wind to act on the cans in the appropriate direction, ensuring sufficient driving force while reducing the ineffective loss of wind power and improving the efficiency of wind power utilization when pushing the cans to move, arrange and reflux. If the angle a is too small, the processing difficulty will be higher, the strength of the channel plate 3 will be lower, and the upper limit of the number of air holes that can be opened will also be reduced; if the angle a is too large, the effect of the wind pushing will be worse and the utilization efficiency will be lower. Therefore, in this embodiment, the preferred angle a is 25 degrees, which can ensure sufficient driving force, reduce the ineffective loss of wind power, and improve the efficiency of wind power utilization.

[0051] In some other embodiments, the angle a may be set to 15 degrees, which may result in a higher degree of processing difficulty. In some other embodiments, the angle a may be set to 45 degrees, which may result in a poorer wind propulsion effect.

[0052] In this embodiment, please refer to Figure 1 , by installing a fan and a duct on the frame 1, the fan input end is connected to an air filter box that can filter the air, the fan output end is connected to the duct, the duct is connected to the air inlet 21, and the air generated by the fan enters the main air supply chamber 22 through the duct and the air inlet 21. A guide part is installed on the box body 2, and a guide channel is provided in the guide part for multiple cans to enter side by side and keep them in a laid-down state and move out to be transported between two channel plates 3. The entrance of the guide channel is connected to the end of the can air conveying belt. The cans move side by side from the air conveying line to the guide part, pass through the guide channel and enter between the two channel plates 3. The fan, duct, air filter box and guide part are all existing technologies and will not be described here.

[0053] After the cans of this embodiment pass through the guide channel of the guide part and enter between the two channel plates 3, they will fall to the return guide plate 5 due to gravity, and after passing through the upper guide surface 51, they will move to the area where the floating air holes 32 are distributed. The floating air holes 32 will blow the cans upward, and the rising cans will also push the adjacent cans above them to move upward, so that the cans are in an irregular dynamic floating state. Under the action of the floating air holes 32, the cans will be in the area where the track air holes 31 are closely arranged above.

[0054] The track air holes 31 have a tendency to transport the cans along their U-shaped distribution track, and the cans are transported along the U-shaped distribution track of the track air holes 31 and finally discharged. The air flow blown in between the channel plates 3 is discharged outwardly through the ventilation air holes 34.

[0055] In this embodiment, the track air holes 31 cooperate with the corresponding upper conveying chamber 23, lower conveying chamber 24, and discharge reflux chamber 25 to use wind force to push the cans to move along the set U-shaped trajectory; the floating air holes 32 use the wind force of the floating air chamber 26 and the discharge reflux chamber 25 to blow the cans upward to achieve the floating arrangement of the cans; the back-blowing air holes 33 use the wind force of the discharge reflux chamber 25 to blow back the offset or redundant cans so that they can re-participate in the arrangement and transportation. The four wind zones work together to achieve orderly transportation of the cans.

[0056] In some embodiments, see Figure 4 and Figure 5 The distribution area of ​​the track air holes 31 includes an upper straight segment area 311, an upper arc segment area 312, a lower arc segment area 313, and a lower straight segment area 314 connected in sequence. The upper straight segment area 311 and the upper arc segment area 312 both coincide with the horizontal projection of the upper conveying chamber 23. The distribution area of ​​the upper floating air holes 32 is adjacent to the lower straight segment area 314 and is located above the lower straight segment area 314. The two channel plates 3 are each provided with a return flow guide plate 5 on the end surface facing each other. The return flow guide plate 5 includes an upper guide surface 51 and a lower guide surface 52. The distribution area of ​​the back-blowing air holes 33 is located in the area surrounded by the lower guide surface 52, the lower straight segment area 314, and the distribution area of ​​the upper floating air holes 32.

[0057] The horizontal projection of the centerline of the track air holes 31 in the upper straight segment area 311 is horizontal, the horizontal projection of the centerline of the track air holes 31 in the lower straight segment area 314 is horizontal, and the horizontal projection of the centerline of the track air holes 31 in the upper arc segment area 312 and the lower arc segment area 313 are tangent to the arc of the track on which they lie. The horizontal projection of the centerline of the floating air hole 32 is vertical, and the horizontal projection of the centerline of the back-blowing air hole 33 is horizontal.

[0058] In this embodiment, the track air holes 31 guide the cans to pass through the upper straight section area 311, the upper arc section area 312, the lower arc section area 313 and the lower straight section area 314 in sequence, thereby realizing orderly transportation from the starting position to the discharge position.

[0059] Specifically, the generated wind force pushes the cans upward, causing them to be closely arranged in the upper straight section area 311. When the cans move to the upper straight section area 311, the track air holes 31 blow the cans, causing the cans to move to the upper arc section area 312, the lower arc section area 313, and the lower straight section area 314 in sequence, and finally be discharged.

[0060] It should be noted that when the cans are offset during the transportation process or enter the discharge channel abnormally, they will reach the distribution area of ​​the back-blowing air holes 33. The wind blown out by the back-blowing air holes 33 will blow them along the lower guide surface 52 of the reflux guide plate 5 to the area of ​​the floating air holes 32, and then be blown again by the floating air holes 32 to realize the reflux rearrangement of the cans and ensure the continuity and stability of the transportation process.

[0061] In some embodiments, see Figures 3 to 6 , two channel plates 3 are provided with guide components 6 on the end surfaces facing each other, the guide components 6 include a conveying guide plate 61 and a discharge adjustment plate 62, the conveying guide plate 61 is located outside the distribution area of ​​the track air hole 31, the inner wall of the conveying guide plate 61 is adapted to the U-shaped distribution track of the track air hole 31, the conveying guide plate 61 includes an upper straight guide section 611, a semicircular reversing guide section 612 and a lower straight guide section 613, and the inner side of the conveying guide plate 61 is a U-shaped structure; the discharge adjustment plate 62 is located between the return guide plate 5 and the lower layer A discharge channel is formed between the linear guide sections 613 and between the discharge adjustment plate 62 and the lower linear guide section 613. A mounting hole 621 is provided on the discharge adjustment plate 62. The mounting hole 621 is a waist-shaped hole. The discharge adjustment plate 62 and the channel plate 3 are connected by bolts. An internal threaded hole 35 adapted for the bolt is provided on the channel plate 3. The bolt passes through the mounting hole 621 and is threadedly connected to the channel plate 3. When the bolt is not tightened on the discharge adjustment plate 62, it can move relative to the mounting hole 621 along the length direction of the mounting hole 621.

[0062] It can be understood that the U-shaped inner wall of the conveying guide plate 61 is adapted to the U-shaped trajectory of the track air hole 31. When the wind pushes the cans to move along the track air hole 31, the conveying guide plate 61 plays a limiting and guiding role, preventing the cans from deviating from the predetermined path and ensuring that they move smoothly along the upper straight guide section 611, the semicircular reversing guide section 612 and the lower straight guide section 613.

[0063] The discharge adjustment plate 62 is connected to the channel plate 3 by bolts. When different sizes of cans need to be conveyed, the bolts are loosened and the discharge adjustment plate 62 can be moved up and down to change the height of the discharge channel. After adjustment, the bolts are tightened to secure the plate. This ensures that cans of various sizes can be discharged smoothly through the discharge channel, meeting diverse production needs. The discharge adjustment plate 62 is also short in length, making it easy to adjust.

[0064] In some embodiments, see Figure 2 and Figure 3The single-channel air conveyor also includes a paddle mechanism 7, which includes a paddle shaft 71 and a drive motor 72. The paddle shaft 71 is rotatably connected to the box body 2 through a bearing, and the paddle shaft 71 is located between the discharge adjustment plate 62 and the distribution area of ​​the back-blowing air holes 33. The drive motor 72 is installed on the box body 2, and the drive motor 72 is connected to the paddle shaft 71 through a coupling. The paddle shaft 71 is used to paddle the contacted cans to the side away from the discharge adjustment plate 62, and the gap between the paddle shaft 71 and the lower linear guide section 613 is for the cans to pass through in a single row.

[0065] It is understandable that the cans may float up and down due to the action of wind. When they move to between the lower straight guide section 613 and the discharge adjustment plate 62, the cans that are offset upward will abut against the can shifting shaft 71. The drive motor 72 drives the can shifting shaft 71 to rotate continuously. The can shifting shaft 71 shifts the cans toward the distribution area of ​​the back-blowing air holes 33. After the shifted cans enter the distribution area of ​​the back-blowing air holes 33, they are back-blown by the back-blowing air holes 33 to the area of ​​the upper floating air holes 32. The upper floating air holes 32 then blow the cans upward again, so that the cans move to the upper straight section area and are rearranged and transported, thereby realizing high-speed and stable operation of the cans from multiple channels to single channel, reducing the probability of can blockage, and improving the stability and reliability of equipment operation.

[0066] In some embodiments, see Figure 3 A back-blowing housing 8 is further provided. The back-blowing housing 8 is fixedly connected to the channel plate 3. The output end of the back-blowing housing 8 blows air toward the distribution area of ​​the back-blowing holes 33. The blowing direction of the output end of the back-blowing housing 8 is the same as the delivery direction of the delivery holes in the upper straight section area 311, and is opposite to the delivery direction of the delivery holes in the lower straight section area 314.

[0067] By setting up the back-blowing shell 8 and blowing air to the distribution area of ​​the back-blowing holes 33, the cans above the cup-pickup shaft 71 can be blown to the distribution area of ​​the back-blowing holes 33, avoiding the upper part of the cup-pickup shaft 71 pushing the cans to the lower part of the downward guide surface.

[0068] It can be understood that the back-blowing shell 8 can provide reverse thrust when the cans flow back, prompting them to smoothly change the direction of movement and return to the correct conveying path, thereby achieving efficient reflux and re-conveyance.

[0069] In order to facilitate the supply of air to the back-blowing shell 8, an air outlet 27 is provided on the box body 2, the cross-section of the air inlet 21 is larger than the cross-section of the air outlet 27, and a gate assembly 4 for adjusting the ventilation volume of the air outlet 27 is provided on the box body 2 and located at the air outlet 27. The air outlet 27 is connected to the input end of the back-blowing shell 8 through a connecting pipe, and the connecting pipe is not shown.

[0070] The sizes of the components of the gate assembly 4 installed at the air outlet 27 and the vent are slightly different, but the structural principles are the same. Figure 5 and Figure 7 The gate assembly 4 includes an air adjustment frame 41, an air adjustment door 42, an air adjustment rod 43, and an air adjustment nut 44. The air adjustment frame 41 and the air adjustment nut 44 are fixedly connected to the housing 2. The air adjustment rod 43 is threadedly connected to the air adjustment nut 44. The air adjustment rod 43 is rotatably connected to the air adjustment door 42 through a bearing. A handle can be installed on the air adjustment rod 43 to facilitate rotation of the air adjustment rod 43.

[0071] The air regulating frame 41 of the gate assembly 4 installed at the air outlet 27 is located outside the air outlet 27, and the air regulating door 42 can open and close the air outlet 27. The air regulating frame 41 of the gate assembly 4 installed at the vent is located outside the vent, and the air regulating door 42 can open and close the vent.

[0072] It should be noted that when the operator rotates the air regulating rod 43, since the air regulating rod 43 is threadedly connected to the air regulating nut 44, the rotation of the air regulating rod 43 will be converted into linear motion, driving the air regulating door 42 to move up and down. The movement of the air regulating door 42 changes the opening size of the vent or air outlet 27, thereby controlling the air volume and air pressure entering the corresponding cavity. For example, when it is necessary to increase the wind force in a certain cavity, rotate the air regulating rod 43 clockwise to move the air regulating door 42 upward, increasing the opening of the vent or air outlet 27; conversely, rotate the air regulating rod 43 counterclockwise to move the air regulating door 42 downward, reducing the opening of the vent or air outlet 27, thereby achieving precise control of the wind system.

[0073] In this embodiment, a total of 5 gate valve assemblies are provided to adjust the air volume of the air outlet 27 and the four ventilation ports respectively, thereby adjusting the air volume entering the back-blowing air shell 8, the upper conveying chamber 23, the lower conveying chamber 24, the discharge reflux chamber 25 and the upper floating air chamber 26. Compared with the number of partitions in the prior art, one gate valve assembly can be reduced, making it easier to adjust the wind pressure.

[0074] In some embodiments, two channel plates 3 are provided with a DLC coating on their facing end surfaces. The channel plates 3 are electroplated, polished, and then coated with the DLC coating. DLC coating, also known as diamond-like carbon film, has high hardness and excellent tribological properties, reducing the coefficient of friction and preventing aluminum powder from adhering, significantly reducing cleaning and maintenance work on the channel plates 3.

[0075] In some embodiments, see Figure 1 and 4, a single-channel air conveyor is also provided, which includes a spacing adjustment mechanism 9. The spacing adjustment mechanism 9 includes a movable frame 91, a screw lift 92, a transmission shaft 93, and a linear slide rail 94. A movable frame 91 is installed at both ends of one box body 2. A screw lift 92 is installed on the movable frame 91. The two screw lifts 92 are connected by a transmission shaft 93. The screw lift 92 is connected to the transmission shaft 93 through a coupling. The screw of the screw lift 92 is its output end and is connected to the frame 1. A linear slide rail 94 is fixed on the frame 1, and the movable frame 91 is connected to the slider of the linear slide rail 94.

[0076] It should be noted that when the distance between the two channel plates 3 needs to be adjusted to accommodate cans of different lengths, the screw lift 92 is rotated, and the screw of the screw lift 92 rotates, driving the movable frame 91 connected thereto to move left and right along the linear slide rail 94.

[0077] Since the two screw lifts 92 are connected via the transmission shaft 93, synchronization between the two ends of the box body 2 can be ensured to achieve precise adjustment.

[0078] The wind generated by the fan is delivered to the air inlet 21 of the box body 2 through the wind tube, providing power for the entire wind power delivery system.

[0079] A hand wheel is installed at the input end of one of the screw lifts 92 , and the screw lift 92 can be driven to move by rotating the hand wheel.
