Description

Technical Field

[0001] The invention belongs to the field of tobacco production equipment, and in particular relates to a high-speed bead implanting machine. Background Art

[0002] "Exploding beads" refer to beads embedded in tobacco filters that can be squeezed and contain flavoring liquid. When squeezed, they feel like bursting. They wrap the flavoring liquid. Smokers can pinch them to burst during smoking to make the liquid in the beads flow out, making the cigarette taste richer and more fragrant, giving smokers a more comfortable experience.

[0003] During the production process of the filter rod of the popping bead cigarette, the popping beads need to be implanted into the filter rod using a bead planting device. In the bead planting device, the whole process includes the steps of material distribution, bead taking, and bead planting. At present, the maximum operating speed of the high-speed bead planting device abroad can reach 350m / min, but it has extremely high requirements for the size and specifications of the raw material popping beads, and it is difficult to adapt to the quality status of domestic popping beads. In addition, to achieve high-speed or even ultra-high-speed operation of the bead planting device, the following technical problems are usually solved: when distributing materials, the popping beads should be prevented from contacting with the sharp edges of the filter screen in the silo to cause damage; when taking the beads from the bead plate, the problem of "bridging" caused by the popping beads sticking together when rotating at high speed and being difficult to be centrifugally thrown into the storage channel should be solved; when the bead plate and the bead planting plate are docked to transport the popping beads, the material distribution guard plate needs to be able to achieve lossless material distribution to avoid collision and damage between the popping beads and the edges of the material trough of the material distribution guard plate. In response to the above problems, the applicant combined his previous products, updated his ideas and made new equipment, which can use domestically produced popping beads with slightly lower quality than foreign ones for production. The current test speed can reach 420m / min. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a high-speed bead planting machine, aiming to overcome the shortcomings of ordinary bead planting equipment in the prior art, such as slow bead planting speed or high bead breakage rate when the bead planting speed increases, which requires higher requirements on the quality of the beads.

[0005] The technical solution of the present invention to solve the above technical problems is as follows: a high-speed bead planting machine, including a frame, a lifting mechanism, a mounting plate and an air distribution mechanism are installed on the frame, the lifting mechanism can drive the mounting plate to rise and fall, and it also includes a lossless material distribution component, a bead taking component and a bead planting component installed on the mounting plate, the bead taking component includes a first driving motor, a base and a bead taking plate, the first driving motor can drive the bead taking plate to rotate relative to the base and a material bin for accommodating bursting beads is formed between the base and the bead taking plate, the lower end discharge port of the lossless material distribution component passes through the base and is connected to the material bin, the base is provided with a bulging channel for decelerating the bursting beads in the material bin, the edge of the bead taking plate is provided with a material storage channel, a material picking tooth for accelerating the bursting beads and an air passage for blowing air to disturb the bursting beads, the bead planting component includes a second driving motor, an air distribution plate and a bead planting plate, the second driving motor can drive the bead planting plate to rotate relative to the air distribution plate, and the bead planting plate is docked with the edge of the bead taking plate to transport the bursting beads.

[0006] Based on the above technical solution, the present invention can also be improved as follows.

[0007] Furthermore, the lossless material distribution component includes an outer cylinder and an inner cylinder, and the upper and lower end openings of the outer cylinder are respectively connected with an upper end cover and a lower end cover with a center hole, the upper surface of the upper end cover is fixedly connected with a first end cover connector with a feed channel, and the lower surface of the lower end cover is fixedly connected with a second end cover connector with a discharge channel, the outer cylinder is made of hard material and a first exhaust hole is opened on the cylinder wall, and the inner cylinder is a soft filter mesh cylinder, and the upper and lower ends of the inner cylinder pass through the center holes of the upper end cover and the lower end cover respectively and are connected with the feed channel and the discharge channel respectively.

[0008] Furthermore, there are multiple first exhaust holes on the outer tube and they are evenly spaced in the circumferential direction of the outer tube. Each of the first exhaust holes is a waist hole whose long axis is parallel to the central axis of the outer tube. The inner tube is a plastic mesh tube with a mesh size smaller than the outer diameter of the bursting beads.

[0009] The advantage of adopting the above-mentioned further structural improvement is that the bursting beads enter the inner cylinder through the first end cover connector under the action of the airflow of the pneumatic feeding device. The inner cylinder adopts a soft filter mesh cylinder. The positive pressure airflow that plays a conveying role during feeding escapes into the atmosphere through the mesh cylinder wall and the exhaust holes of the outer cylinder, and will not enter the bead taking plate of the bead taking device below with the bursting beads, so it will not have an adverse effect on the bead taking process; the contact between the bursting beads and the mesh cylinder wall is soft contact, especially when the filter mesh cylinder is made of non-metal such as nylon or polyester, there will be no sharp edges and corners, so the mesh cylinder wall will not damage the bursting beads during the material separation process (separation of the bursting beads from the air), which is beneficial to avoid a series of problems caused by damage to the bursting beads.

[0010] Further, the base includes a disc-shaped seat body, the front side surface of the seat body is concave to form a circular groove, the center of the rear side surface of the seat body is convex to form a mounting column, the mounting column is coaxial with the seat body and a penetrating mounting channel is opened at the center, and the area of ​​the seat body outside the mounting column is penetrated by a feed hole and a material level detection hole connected to the circular groove in the front and rear, and a plurality of groups of expansion channels are formed in a concave manner on the bottom surface of the circular groove, each group of the expansion channels includes a first expansion channel and a second expansion channel connected to each other, and the concave depth of the second expansion channel is greater than the concave depth of the first expansion channel.

[0011] Further, the first expansion channel is an arc groove concentric with the circular groove, the second expansion channel is a circular groove, and the second expansion channel is located at one end of the first expansion channel.

[0012] The advantage of adopting the above-mentioned further structural improvement is that when multiple explosive beads with faster speeds form a "bridge" phenomenon, they experience a deceleration when entering the arc groove. Each explosive bead is decelerated in turn, some first and some later, thus forming a speed difference, so that the explosive beads that were originally close to each other are separated, destroying the "bridge" phenomenon. If the first deceleration fails to fully destroy the "bridge", it will experience deceleration again when entering the deeper second expansion channel, causing secondary destruction, thereby enhancing the effect of destroying the "bridge".

[0013] Furthermore, the bead picking plate includes a circular disc body, the middle part of the rear side surface of the disc body is concave to form a circular material trough, the center of the bottom of the circular material trough is provided with an axial hole for the rotating shaft to pass through and be fixedly connected, the side wall of the circular material trough is close to the bottom of the trough and is evenly spaced in the circumferential direction with a plurality of the material-selecting teeth, a material sorting trough is formed between two adjacent material-selecting teeth, a plurality of the material storage channels are evenly spaced in the circumferential direction on the edge of the disc body and correspond one-to-one to the material sorting troughs, the inner end opening of the material storage channel is connected to the material sorting trough, and the outer end opening is located on the cylindrical side surface of the outer side of the disc body, the edge of the disc body is also evenly spaced in the circumferential direction with the air passages connected one-to-one to the material sorting troughs and the air intake channels connected one-to-one to the air passages, and the disc body is also provided with a second exhaust hole connecting the outside atmosphere and the circular material trough.

[0014] The advantage of adopting the above-mentioned further structural improvement is that the material-selecting teeth can make the bursting beads entering the material sorting trough quickly obtain following power, and then rotate at the same speed as the bead taking plate, and enter the material storage channel under the action of centrifugal force. The bursting beads enter the material storage channel one by one and are arranged in a row, which is convenient for the later docking with the bead planting plate components and the bursting bead transfer; the air passage and air inlet channel arranged at the edge of the bead taking plate can realize the introduction of airflow into the material sorting trough, and the airflow acts on the bursting beads in the material sorting trough and disturbs them, thereby playing a role in destroying the "bridging" phenomenon.

[0015] Furthermore, the material storage channel and the air passage channel are both arranged along the radial direction of the disc body, the air passage channel and the air inlet channel are perpendicular to each other, and the air inlet of the air inlet channel is located on the annular surface of the rear side edge of the disc body.

[0016] The advantage of adopting the above-mentioned further structural improvement is that the radially opened channel has the advantage of easy processing. At the same time, the radial material storage channel makes it easier for the bursting beads to enter the channel under the action of centrifugal force and the channel wall has little obstruction to the bursting beads after entering. Under the action of centrifugal force, it is easier to throw out when approaching the bead planting plate component, which is beneficial to improving the efficiency of bursting bead transfer.

[0017] Furthermore, a material guarding plate is provided around the outer periphery of the bead retrieval plate, and the material guarding plate is fixedly connected to the mounting plate. A fracture is formed on the material guarding plate at the docking area between the bead planting plate and the bead retrieval plate to facilitate the transportation of exploded beads. The material guarding plates on both sides of the fracture are respectively a discharge guard plate and a separation guard plate. A material discharge port is provided at one end of the separation guard plate located at the fracture, and an upper end face of the material discharge port is provided with an upper V-groove extending upward, and a lower end face of the material discharge port is provided with a lower V-groove extending upward.

[0018] The advantage of adopting the above-mentioned further structural improvement is that the upper V-groove can ensure that when the diameter of the bursting beads is too small during material discharge, the next bursting bead adjacent to it in the same storage channel of the bead taking plate will not have a large collision with the upper and rear edges of the discharge port as the bead taking plate rotates upward, and the edges (transverse edges) perpendicular to the moving direction of the bursting beads on the discharge trough are changed into two triangular inclined surfaces in the same direction as the moving direction of the bursting beads that constitute the upper V-groove. The bursting beads rotate smoothly upward with the bead taking plate, which can effectively reduce the breakage rate of the bursting beads. In addition, the setting of the lower V-groove can ensure that large-particle bursting beads do not collide with the transverse edges at the lower and rear ends of the discharge port when they are absorbed by the bead planting plate and rotate forward, thereby also achieving the effect of reducing the breakage of the bursting beads.

[0019] Furthermore, a plurality of viewing holes are evenly spaced around the axial hole at the bottom of the circular material trough, a transparent glass plate is embedded in the viewing hole, and the second exhaust hole is opened on the transparent glass plate.

[0020] The advantage of adopting the above-mentioned further structural improvement is that the arrangement of the viewing window hole and the transparent glass plate ensures the effect of storing and removing materials from the bead plate, and can also ensure that the internal situation of the bead plate can be seen from the front side, so that the situation of removing beads from the plate can be observed.

[0021] Furthermore, a soft friction plate is sandwiched between the air distribution disc and the bead planting plate, and an arc-shaped negative pressure air duct concentric with the air distribution disc is provided on the annular disc surface of the air distribution disc facing the friction plate. A plurality of waste grooves are also provided on the annular disc surface, and the waste grooves are spaced apart from the negative pressure air duct in the circumferential direction.

[0022] The advantage of adopting the above-mentioned further structural improvement is that the waste chips generated by friction can enter the waste container without squeezing grooves on the soft friction plate, which effectively solves the problem of poor working stability of the equipment caused by cross-flow due to the generation of grooves in the prior art.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. The bead taking component of the high-speed bead planting machine provided by the present invention can effectively eliminate the bridging phenomenon of the bursting beads when the bead taking plate is running at high speed through a unique structural design: first, the dynamic and static coordination between the bead taking plate base and the bead taking plate will provide a resistance to the bursting beads, and the bursting beads in the material bin are in a rolling state, that is, the bursting beads will rotate to a certain extent; secondly, a bulging channel is provided on the base, and in the bulging channel, the bursting beads will reduce their speed due to the change in the cross-sectional area of ​​the channel, so that there will be relative movement between the bursting beads, destroying the bridging phenomenon; finally, in addition to the material storage channel, the material sorting trough between the adjacent material picking teeth on the bead taking plate also has an air passage channel for destroying the bridging, and the airflow in the air passage can disturb the bursting beads in the material sorting trough to cause displacement of the bursting beads that are relatively close to each other, thereby achieving the purpose of destroying the bridging. The above three aspects work together to effectively eliminate the bridging phenomenon of the bursting beads and ensure that the beads are taken stably when the bead taking plate is running at high speed.

[0025] 2. The present invention also has a non-destructive material separation component, the inner cylinder of which is a soft filter mesh cylinder made of non-metal such as nylon or polyester, and has no sharp edges and corners. Therefore, the mesh cylinder wall will not damage the bursting beads during the material separation process (separation of bursting beads from air), which is conducive to avoiding damage to the bursting beads;

[0026] 3. In the bead-planting assembly of the present invention, a plurality of material containing grooves are provided on the annular surface where the air distribution disc contacts the soft friction plate. During running-in, the waste chips generated by the friction can enter the material containing grooves without squeezing out grooves on the soft friction plate. This effectively solves the problem in the prior art of poor working stability of the equipment due to cross-flow caused by the generation of grooves. In actual work, the running-in efficiency is increased by more than 4 times, which greatly reduces the workload during running-in.

[0027] 4. The upper and lower surfaces of the discharge port at the lower end of the separation guard plate at the joint between the bead taking plate and the bead planting plate of the present invention are arranged as a double V-groove structure, which can allow the smooth passage of larger diameter bursting beads downward, and allow the passage of smaller diameter bursting beads upward, which can appropriately reduce the requirements for the uniformity of the diameter of the bursting beads and reduce the breakage rate; it can provide a relatively longer time for the bead planting plate to adsorb the bursting beads and ensure higher-speed docking stability.

[0028] 5. Combining the above structural improvements, the high-speed bead planting machine provided by the present invention can use domestically produced explosive beads of slightly lower quality than foreign ones for production, and can currently achieve ultra-high-speed normal production operation of 420m / min.

DETAILED DESCRIPTION

[0057] The principles and features of the present invention are described below in conjunction with the accompanying drawings and specific embodiments. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0058] In the description of the present invention, if terms indicating orientation such as "up", "down", "left", "right", "top", "bottom", "inside" and "outside" are used, the orientation or position relationship indicated is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0059] like Figures 1 to 26 As shown, the present invention provides a high-speed bead planting machine, including a frame frame 1, on which a lifting mechanism 2, a mounting plate 3 and a gas distribution mechanism 4 are installed, the lifting mechanism 2 can drive the mounting plate 3 to rise and fall, and it also includes a lossless material distribution component 5, a bead taking component and a bead planting component installed on the mounting plate 3, the bead taking component includes a first driving motor 6, a base 7 and a bead taking plate 8, the first driving motor 6 can drive the bead taking plate 8 to rotate relative to the base 7 and a material bin for accommodating burst beads is formed between the base 7 and the bead taking plate 8, the lossless material distribution component 5 can drive the bead taking plate 8 to rotate relative to the base 7 and a material bin for accommodating burst beads is formed between the base 7 and the bead taking plate 8, The lower end discharge port of the material component 5 passes through the base 7 and is connected to the material bin. The base 7 is provided with an inflation channel for decelerating the bursting beads in the material bin. The edge of the bead taking plate 8 is provided with a material storage channel 9, a material selection tooth 10 for accelerating the bursting beads and an air passage 11 for blowing air to generate disturbance on the bursting beads. The bead planting component includes a second drive motor 12, an air distribution plate 13 and a bead planting plate 14. The second drive motor 12 can drive the bead planting plate 14 to rotate relative to the air distribution plate 13, and the bead planting plate 14 is docked with the edge of the bead taking plate 8 to transport the bursting beads.

[0060] It should be noted that the lifting mechanism and the air distribution mechanism are existing devices, wherein the air distribution mechanism may include a blowing device and an air suction device, which can supply compressed air to the air passage of the bead retrieval plate of the bead retrieval assembly, and can also generate negative pressure at the negative pressure air passage of the air distribution plate of the bead planting assembly.

[0061] In one embodiment of the present invention, Figures 4 to 6 As shown, the lossless material distribution component 5 includes an outer cylinder 15 and an inner cylinder 16, and the upper and lower end openings of the outer cylinder 15 are respectively connected with an upper end cover 17 and a lower end cover 18 with a center hole, and the upper surface of the upper end cover 17 is fixedly connected with a first end cover connector 19 with a feed channel, and the lower surface of the lower end cover 18 is fixedly connected with a second end cover connector 20 with a discharge channel. The outer cylinder 15 is made of hard material and a first exhaust hole 21 is opened on the cylinder wall. The inner cylinder 16 is a soft filter mesh cylinder, and the upper and lower ends of the inner cylinder 16 pass through the center holes of the upper end cover 17 and the lower end cover 18 respectively and are connected with the feed channel and the discharge channel respectively.

[0062] On the basis of the above embodiment, there are multiple first exhaust holes 21 on the outer cylinder 15 and they are evenly spaced in the circumferential direction of the outer cylinder 15. Each of the first exhaust holes 21 is a waist hole whose long axis is parallel to the central axis of the outer cylinder 15. The inner cylinder 16 is a plastic mesh cylinder with a mesh size smaller than the outer diameter of the bursting beads.

[0063] It should be noted that the connection between the upper end cover and the first end cover connector, and the connection between the lower end cover and the second end cover connector can be fixed by bolts, the first and second outer flanges of the inner tube can be pre-arranged with through holes for the bolts to pass through, and the upper end cover and the lower end cover are provided with screw holes that match the bolts. The upper end cover and the lower end cover can be integrally formed with the outer tube or detachably connected (such as threaded connection). The basic principle of lossless material distribution is that the bursting beads enter the inner cylinder through the first end cover connector under the action of the airflow of the pneumatic feeding device. The inner cylinder adopts a soft filter mesh cylinder. The positive pressure airflow that plays a conveying role during feeding escapes into the atmosphere through the mesh cylinder wall and the exhaust holes of the outer cylinder, and will not enter the bead taking plate of the bead taking device below with the bursting beads, so it will not have an adverse effect on the bead taking process; the contact between the bursting beads and the mesh cylinder wall is soft contact, especially when the filter mesh cylinder is made of non-metal such as nylon or polyester, there will be no sharp edges and corners, so the mesh cylinder wall will not damage the bursting beads during the material distribution process (separation of bursting beads from air), which is beneficial to avoid a series of problems caused by damage to the bursting beads.

[0064] In one embodiment of the present invention, Figure 16-19As shown, the base 7 includes a disc-shaped seat body 22, the front side surface of the seat body 22 is concave to form a circular groove 23, the center of the rear side surface of the seat body 22 is convex to form a mounting column, the mounting column is coaxial with the seat body 22 and a penetrating mounting channel is opened at the center, and the area of ​​the seat body 22 outside the mounting column is penetrated by a feed hole 24 and a material level detection hole 25 connected to the circular groove 23, and a plurality of groups of expansion channels are formed in a concave manner on the bottom surface of the circular groove 23, each group of the expansion channels includes a first expansion channel 26 and a second expansion channel 27 connected to each other, and the concave depth of the second expansion channel 27 is greater than the concave depth of the first expansion channel 26. The first and second expansion channels have different concave depths (the former is shallow and the latter is deep). Due to the high-speed rotation of the bead retrieval plate, the bursting beads rotating at a higher speed can be decelerated twice in the first and second expansion channels. During deceleration, the adjacent bursting beads that were originally connected together due to the "bridging" phenomenon are separated and dispersed from each other due to the speed change, which plays a role in destroying the "bridging", which is conducive to the bead retrieval plate to complete the bead retrieval process more smoothly.

[0065] On the basis of the above embodiment, the first expansion channel is an arc groove concentric with the circular groove 23, and the second expansion channel 27 is a circular groove and the second expansion channel 27 is located at one end of the first expansion channel 26. It can be understood that the second expansion channel can also be arranged in the middle of the first expansion channel, which can also play a role in destroying the "bridge". In addition, the second expansion channel can also be an arc groove deeper than the first expansion channel.

[0066] It should be noted that the feed hole is located at the upper middle part of one side of the seat body and penetrates the seat body obliquely downward from the back to the front, and the material level detection hole is located at the lower middle part of the seat body, so as to achieve the purpose of monitoring the amount of beads in the material bin corresponding to the circular groove. The material bin is essentially composed of the circular groove 23 of the base and the circular material groove 29 of the bead taking plate described below.

[0067] In one embodiment of the present invention, Figures 7 to 15As shown, the bead picking plate 8 includes a disc body 28, the middle part of the rear side surface of the disc body 28 is concave to form a circular material trough 29, the center of the bottom of the circular material trough 29 is provided with an axial hole for the rotating shaft to pass through and be fixedly connected, the side wall of the circular material trough 29 is evenly spaced in the circumferential direction near the bottom of the trough and a plurality of the material picking teeth 10 are evenly spaced, and a material sorting trough 30 is formed between two adjacent material picking teeth 10, and a plurality of the material storage channels 9 are evenly spaced in the circumferential direction and opened on the edge of the disc body 28 The material storage channel 9 has an inner opening which is connected to the material storage channel 30, and an outer opening which is located on the cylindrical side surface outside the disc body 28. The edge of the disc body 28 is also provided with air passages 11 which are connected to the material storage channel 30 in a one-to-one manner, and air inlet channels 31 which are connected to the air passages 11 in a one-to-one manner. The disc body 28 is also provided with a second exhaust hole 32 which is connected to the outside atmosphere and the circular material trough 29.

[0068] It should be noted that the material-selecting teeth can enable the bursting beads entering the material sorting trough to quickly obtain following power, and then rotate at the same speed as the bead taking plate, and enter the material storage channel under the action of centrifugal force. The bursting beads enter the material storage channel one by one and are arranged in a row, which is convenient for the later docking with the bead planting plate components and the bursting bead transfer; the air passage and air inlet channel arranged on the edge of the bead taking plate can realize the introduction of air flow into the material sorting trough, and the air flow acts on the bursting beads in the material sorting trough and disturbs them, thereby playing a role in destroying the "bridging" phenomenon, ensuring that the beads can be smoothly taken even when the bead taking plate rotates at ultra-high speed.

[0069] Based on the above embodiment, the material storage channel 9 and the air passage channel 11 are both arranged along the radial direction of the disc body 28, the air passage channel 11 and the air inlet channel 31 are perpendicular to each other and the air inlet of the air inlet channel 31 is located on the annular surface of the rear edge of the disc body 28.

[0070] It should be noted that the material storage channel and the air passage channel do not have to be arranged radially and do not have to be straight channels. They can also be in other forms according to needs, such as a curve with a certain curvature. In particular, the air passage channel can have a variety of shapes as long as it can achieve the ventilation function. The above-mentioned radially opened air passage is located on the hole on the cylindrical surface outside the disc body. After the air passage is opened, it can be closed with sealing materials to prevent air leakage to the outside. If it is not blocked, it can also be closed by the outer material guard plate. A gas distribution block (such as Fig.10 As shown), the air distribution block is connected with the air distribution mechanism, and compressed air can be delivered to each air inlet channel through the air distribution block; an arc-shaped air distribution groove is provided on the air distribution block, and when the disc body rotates, each air inlet channel located on the annular surface can intake air from the air distribution groove when passing through the air distribution groove.

[0071] On the basis of the above-mentioned embodiment, the outer periphery of the bead taking plate 8 is surrounded by a material guarding plate 33, and the material guarding plate 33 is fixedly connected to the mounting plate 3. The material guarding plate 33 forms a fracture in the docking area between the bead planting plate 14 and the bead taking plate 8 to facilitate the transportation of burst beads. The material guarding plates 33 on both sides of the fracture are respectively a discharging guarding plate and a distributing guarding plate. Figure 23-25 As shown, a material discharge port 34 is formed at one end of the material separation guard plate located at the fracture, an upper end surface of the material discharge port 34 is provided with an upper V-groove 35 extending upward, and a lower end surface of the material discharge port 34 is provided with a lower V-groove 36 extending upward.

[0072] It should be noted that the size uniformity of domestically produced blasting beads is relatively poor, with some having slightly larger diameters and others having slightly smaller diameters. In order to ensure that all blasting beads can be smoothly removed and transported, the depth of the discharge trough is usually just the same as that of the large-diameter blasting beads. In this way, when a small-diameter blasting bead is sucked away by the bead planting plate, another blasting bead in the bead plate storage channel that is adjacent to the removed small-diameter blasting bead will collide and squeeze with the upper edge of the rear end of the discharge trough as the bead plate rotates upward (that is, it needs to "climb" upward), which will cause the blasting beads to rupture and be damaged. The larger the proportion of small-diameter blasting beads, the more serious the rupture of the blasting beads during actual production. In addition, when the bead planting plate removes the blasting beads and continues to rotate, if the diameter of the adsorbed blasting beads is too large, it is easy to collide and squeeze with the lower edge of the rear end of the discharge trough, causing damage to the blasting beads. In order to solve the above problems and enable the use of domestically produced blasting beads, the above-mentioned material separation guard plate with double V-grooves is designed. Specifically, Fig.26 As shown, the upper V-groove can be composed of two triangular inclined surfaces 37 with a common bottom edge, and the lower V-groove can be composed of two triangular inclined surfaces 37 with a common top edge. It can be understood that the upper and lower V-grooves can be other than the above-mentioned forms, and can also be smooth arc-shaped grooves, the lower ends of which are wider and located on both sides of the feed opening and gradually tighten and narrow upwards.

[0073] In one embodiment of the present invention, Fig.11 and 15 As shown, the bottom of the circular trough 29 is provided with a plurality of window holes 38 evenly spaced around the axial hole, a transparent glass plate is embedded in the window hole 38, and the second exhaust hole 32 is provided on the transparent glass plate.

[0074] In one embodiment of the present invention, the annular disk surface of the gas distribution disk 13 facing the friction plate is provided with a waste groove 40 in addition to the arc-shaped negative pressure air passage 39 concentric with the gas distribution disk 13, and the waste groove 40 is circumferentially spaced from the negative pressure air passage 39. In the prior art, a soft friction plate is sandwiched between the gas distribution disk 13 and the bead-planting disk 14. When the friction plate rotates and runs with the gas distribution disk, the friction will generate waste chips, which can enter the waste groove 40.

[0075] It should be noted that the waste groove is actually a blind hole with a certain depth that does not penetrate the valve plate. Its function is to accommodate the waste generated by the friction when the soft friction plate rotates relative to the valve plate. Figure 20-22 As shown, it is a more preferred solution to set the waste containing groove as an elongated groove extending in the radial direction, but it is not necessary to set it in this way. The technicians in this field can also set the waste containing groove as a circular groove, an elliptical groove or an elongated groove that does not extend in the radial direction, which can also achieve the purpose of accommodating waste chips and reducing the generation of extrusion grooves to a certain extent, and should also be included in the protection scope of the present invention. The number of the waste containing grooves can also be multiple.

[0076] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
