Description

Technical Field

[0001] The utility model relates to the technical field of velvet cotton beating equipment, in particular to a velvet cotton beating machine. Background Art

[0002] Down beating machine, also known as cotton beating equipment or cotton beating machine or down beating machine or clothing down beating machine, is a mechanical device specially used for beating and processing filling materials such as cotton and down. The main function of the down beating machine is to make filling materials such as cotton and down more fluffy and evenly distributed by mechanical beating, thereby improving the warmth retention and comfort of products such as clothing and bedding. Down beating machine is widely used in the fields of clothing processing, home textile production, etc., especially plays an important role in the production process of down jackets, down quilts, cotton clothes and other products.

[0003] Existing cotton lint beating machines are usually equipped with a conveying module for conveying, a beating module for beating cotton lint products, a housing for covering the beating module, etc. For example, a fully automatic cotton lint leveling machine disclosed in Chinese patent CN 114468443 B, an automatic cotton lint beating machine disclosed in Chinese patent CN 219088501 U, and a cotton lint beating machine disclosed in Chinese patent CN208909180 U. The beating module is a core module, which mainly includes a beating power and a cotton beating beater. The cotton beating beater is a component mainly used to contact and beat cotton lint products. The beating power is connected to the cotton beating beater through transmission, and the cotton beating beater is driven by the beating power to perform a beating action. The traditional cotton beating beater is an integral plate-like structure, which has great resistance and high energy consumption during the beating action, and has been gradually eliminated by the market; the existing common cotton beating beater is usually a combination structure composed of multiple beater bars, and there is a gap between the beater bars, which can not only increase the beating area, but also facilitate exhaust and reduce air resistance during the beating action. However, it is found in actual application that this structure of the cotton-beating paddle is prone to damage the fabric surface of cotton and down products, especially down fabrics, during the process of contact and beating with the fabric surface of the cotton and down products. One reason is that the contact area between the beater in the cotton-beating paddle and the fabric surface is relatively small, and there is a gap between adjacent beater bars, which leads to a large positive beating force in a local area of ​​the fabric surface during the contact between the beater bars and the fabric surface, and the stress is relatively concentrated, which can easily cause damage to this area, while the adjacent area is basically not subjected to the positive beating force, thereby forming a certain tearing force between the two areas, which can also easily cause damage to the fabric surface. Therefore, how to effectively prevent damage to the fabric surface while improving the beating effect needs to be solved urgently. Summary of the invention

[0004] The first aspect of the utility model is to solve the above technical problems and provide a lint-beating machine that can effectively prevent the surface of the fabric of cotton lint products from being damaged. The main concept is:

[0005] A lint-beating cotton machine includes a machine shell and a beating module. The beating module includes a beating power source and a cotton-beating paddle. The beating power source is drivingly connected to the cotton-beating paddle, and the beating power source drives the cotton-beating paddle to perform a beating action. It also includes a protection part. The protection part includes a protective layer covering the lower part of the cotton-beating paddle, and the protective layer is configured as a net. In this solution, by arranging a protective layer covering the lower part of the cotton-beating paddle, the protective layer can be used to contact the cotton flannel products. Since the protective layer is configured as a net, it can not only effectively increase the contact area between the cotton-beating paddle and the cotton flannel products, avoid the problem of stress concentration, and effectively prevent the damage to the surface of the fabric of the cotton flannel products caused by stress concentration during the beating process. Moreover, the net-shaped protective layer can more evenly disperse the beating force during the beating process, so that the beating force can act more evenly on the surface of the fabric of the cotton flannel products, effectively preventing the appearance of tearing force in the beating area. Thus, the problem that the cotton-beating paddle is likely to damage the surface of the cotton flannel products during the beating and contacting process can be effectively solved. It can not only achieve a better beating effect but also play a protective role.

[0006] Preferably, the protective layer is made of a net-shaped fabric, and the protective layer is tensioned on the lower part of the cotton-beating paddle. This is not only more conducive to exhausting air and reducing air resistance during the beating action, thus being more energy-efficient, but also the protective layer in a tensioned state can keep the lower part of the cotton-beating paddle relatively flat, so as to contact the cotton flannel products more evenly and effectively protect the surface of the fabric of the cotton flannel products. In addition, the protective layer in a tensioned state also has a certain elasticity, which can effectively reduce the noise during the beating process and the impact on the beating power source during the beating process, enabling the beating module to operate more stably and smoothly.

[0007] Preferably, the protective layer is a net-shaped fiber mesh. This is more conducive to solving the problem that the surface of the down fabric is easily damaged when being beaten and contacted.

[0008] To solve the problem of facilitating the tensioning of the protective layer, in some solutions, the protective layer is pasted on the lower part of the cotton-beating paddle, or the protective layer is fixed to the lower part of the cotton-beating paddle through fasteners. Thus, the purpose of fixing and tensioning the protective layer is achieved.

[0009] To solve the problem of facilitating the tensioning of the protective layer, in some solutions, the protection part further includes at least two restraint bands. The two ends of the restraint bands are respectively connected to both sides of the protective layer, and the restraint bands are respectively arranged at intervals along the length direction of the protective layer. The protective layer is tensioned on the lower part of the cotton-beating paddle by using the restraint bands. This can not only solve the problem of tensioning the protective layer but also is very convenient for installing and disassembling the protective layer.

[0010] Preferably, the restraint bands are elastic elastic bands, and the protective layer is tensioned by using the elasticity of the elastic bands. The cost is low and it is convenient to use.

[0011] Preferably, the restraint strap includes a first restraint strap and a second restraint strap. One ends of the first restraint strap and the second restraint strap are respectively connected to two sides of the protective layer. The protective layer is tensioned at the lower part of the cotton patting pat through the cooperation of the first restraint strap and the second restraint strap. When assembling the protection part, the first restraint strap and the second restraint strap in the same restraint strap can respectively wind from the side part of the cotton patting pat to the upper part of the cotton patting pat, so that the first restraint strap and the second restraint strap can be connected together, which can not only tension the protective layer, but also effectively prevent the protective layer from falling off.

[0012] To solve the problem of preventing the protective layer from shifting during the patting process, in some solutions, the protection part further includes a skirt connected to the periphery of the protective layer. The skirt is formed in a ring shape, and the protective layer and the skirt jointly form a cap-shaped structure. Two ends of the restraint strap are respectively connected to the skirts on two sides of the protective layer. In this solution, by configuring the skirt, the skirt can correspond to the side part of the protection part, making the wrapping property of the whole protection part for the cotton patting pat better. It can not only achieve the purpose of fixing the protective layer and keeping the protective layer in a tensioned state, but also effectively prevent the protection part from shifting during the patting process, ensuring that the protective layer is always tensioned at the lower part of the cotton patting pat.

[0013] To solve the problem of more convenient use, preferably, the protection part further includes a skirt connected to the periphery of the protective layer. The skirt is formed in a ring shape, and the protection part forms a bag-shaped structure with an opening and adapted to the cotton patting pat, and the protection part is sleeved on the cotton patting pat. This makes the installation and replacement of the protection part very convenient and efficient.

[0014] Further, a ring-shaped elastic band is also arranged at the opening to automatically tighten the opening by using the ring-shaped elastic band. Thus, it is more convenient to fix the protective layer at the lower part of the cotton patting pat, more conducive to quickly tensioning the protective layer, and realizing a more uniform contact and patting effect.

[0015] Further, a tightening channel is arranged at the opening. The tightening channel has a notch, and a drawstring is arranged in the tightening channel. Two ends of the drawstring respectively extend out of the tightening channel through the notch. This enables that during use, the opening can be tightened by tightening the drawstring, and further achieves the purpose of quickly fixing and tensioning the protective layer.

[0016] The second aspect of the utility model aims to solve the problem of reducing noise and increasing the service life of the beating module. Furthermore, the cotton beating racket includes a connecting assembly and at least two beating rods, each of which is connected into a whole through the connecting assembly. The connecting assembly is used to position and constrain the beating rod, and the beating power is connected to the connecting assembly by transmission. The beating rod is a fiber rod. The fiber rod is more durable and has a longer service life. The fiber rod has better elasticity and stronger resilience. By using the fiber rod as the beating rod, on the one hand, the beating effect is better, and on the other hand, the noise of the beating process is smaller. In addition, the impact on the connecting shaft, the transmission mechanism and the beating power during the beating action can be effectively reduced, so that the beating power and the transmission mechanism between the beating power and the cotton beating racket can operate more stably and smoothly, which is conducive to increasing the service life of the beating module.

[0017] Preferably, the racket bar is a round bar, which not only makes the racket bar isotropic and has stronger resilience, but also makes the racket bar free of edges and corners, so that the surface of the cotton wool product is not easily damaged during the beating process.

[0018] Preferably, the racket shaft is made of a glass fiber shaft, a carbon fiber shaft, or an aramid fiber shaft.

[0019] Preferably, it comprises at least two connecting components, each connecting component is evenly distributed along the length direction of the racket bar; each racket bar is parallel to each other.

[0020] In order to solve the problem of accurately positioning the racket rod and facilitating the rapid installation and removal of the racket rod, the connection assembly further includes a connection block and a fastener. The connection block is constructed with an assembly groove that passes through both sides. The assembly groove includes an adapting hole that passes through both sides of the connection block and a connecting groove that connects the two adapting holes. The upper end and the lower end of the connecting groove are respectively constructed with a first locking hole and a second locking hole that are adapted to each other. The first locking hole and the second locking hole are respectively connected to the connecting groove, and the fastener is adapted to the first locking hole and the second locking hole. The racket rod passes through the adapting hole and is clamped in the adapting hole by the fastener. In this solution, the connection block in the connection assembly is an integrated structure, which is not only convenient for processing and forming, but also makes the process of installing and removing the racket rod simpler and more convenient. In addition, it can also effectively avoid the occurrence of sharp corners and acute angles in the structure, thereby effectively protecting cotton wool products and preventing damage to the fabric surface of cotton wool products.

[0021] Preferably, at least one of the first locking hole and the second locking hole is a threaded hole, in which case the fastener is a bolt adapted to the threaded hole; or, both the first locking hole and the second locking hole are blind holes, in which case the fastener is a bolt pair.

[0022] Furthermore, it also includes a conveying module for conveying cotton wool products. The conveying module and the beating module are respectively arranged on the casing. The beating module is located on one side or both sides of the conveying module and cooperates with the conveying module.

[0023] Compared with the prior art, using a lint cotton beater provided by the present utility model can not only achieve a better beating effect, but also protect the surface of the fabric of the lint cotton product, effectively preventing damage to the surface of the fabric of the lint cotton product during the beating process.

[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Usually, the components of the embodiments of the present invention described and shown in the accompanying drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but only represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present invention.

[0042] Embodiment 1

[0043] In this embodiment, a cotton-beating machine is provided, which includes a conveying module 2, a beating module 3 adapted to the conveying module 2, a machine housing 1, etc. Among them, the machine housing 1 generally includes a frame and a housing provided on the frame. The frame is mainly used for bearing, and the housing is mainly used for wrapping the frame and forming a relatively closed internal cavity, as Figure 1 and Figure 2 shown. The machine housing 1 is configured with an inlet 11 and an outlet 12 arranged opposite to each other, as Figure 1 and Figure 2 shown. The conveying module 2 is usually horizontally arranged. One end of the conveying module 2 extends out of the machine housing 1 through the inlet 11 for a certain distance, as Figure 1 and Figure 2 shown, so as to form a feeding table 13 to facilitate the user to place the cotton floss products to be beaten on the conveying module 2; the other end of the conveying module 2 extends out of the machine housing 1 through the outlet 12, as Figure 2As shown, in order to output the beaten cotton wool products; the conveying module 2 can divide the internal cavity in the casing 1 into upper and lower cavities and a lower cavity, wherein the beating module 3 performs beating action in the upper cavity, therefore, the upper cavity can also be called a beating operation space, and the lower cavity can be used to install electrical equipment, etc.

[0044] In implementation, the conveying module 2 can use an existing belt conveyor, such as Figure 1 and Figure 2 As shown, the belt conveyor includes a conveying motor, a driving shaft, a driven shaft and a conveyor belt, the driving shaft and the driven shaft are rotatably mounted on the frame, the conveyor belt is tensioned on the driving shaft and the driven shaft, and the conveying motor is drivingly connected to the driving shaft so as to drive the conveyor belt to circulate in the direction from the inlet 11 to the outlet 12 so as to convey the cotton lint products in a straight line in the direction from the inlet 11 to the outlet 12. In addition, during implementation, the conveying module 2 may also adopt a chain plate conveyor, a ball chain conveyor, etc., which can also achieve the purpose of directional conveying of cotton lint products, and examples are not given here one by one.

[0045] In this embodiment, the flapping module 3 includes a flapping power 31, a connecting shaft 32 and a flapping structure, wherein the connecting shaft 32 can be connected to the bearing seat 14 through a bearing, the bearing seat 14 is fixed to the frame, and the connecting shaft 32 can be arranged along the length direction (or conveying direction) of the conveying module 2, such as Figure 2 As shown, the connecting shaft 32 can be arranged on one side of the conveying module 2. The flapping structure is connected to the connecting shaft 32, and the flapping structure can be arranged along the width direction of the conveying module 2, such as Figure 2 shown.

[0046] The flapping power 31 can be installed on the frame, and the flapping power 31 is connected to the connecting shaft 32 in a transmission manner so as to drive the connecting shaft 32 to rotate, thereby driving the flapping structure to move up and down in a plane perpendicular to the conveying direction of the conveying module 2, such as Figure 2 As shown, the cotton wool products conveyed on the conveying module 2 in the working space are continuously slapped, so that the filling materials in the cotton wool products are more fluffy and more evenly distributed. During implementation, the slapping power 31 can be connected to the transmission shaft through a transmission mechanism, and the transmission mechanism can be a combination of one or more of a belt transmission mechanism, a gear rotation mechanism, a connecting rod transmission mechanism, etc. As an example, in the present embodiment, the slapping power 31 adopts a servo motor, and the transmission mechanism includes an eccentric shaft connected to the output shaft of the servo motor, a first connecting rod and a second connecting rod. The rotation center of the eccentric shaft deviates from the rotation center of the output shaft of the servo motor. One end of the first connecting rod is hinged to the eccentric shaft, and the other end is hinged to the second connecting rod. One end of the second connecting rod is fixedly connected to the connecting shaft 32, so that the servo motor can be used to drive the eccentric shaft to move, and the movement of the eccentric shaft can be used to drive the connecting shaft 32 to rotate forward and reverse, such as Figure 2 and Figure 3As shown, the flapping structure is then driven to complete the flapping action.

[0047] In implementation, the number of flapping structures installed on the connecting shaft 32 can be one, two or three, etc., so that the flapping structures connected to the same connecting shaft 32 can move synchronously under the drive of the connecting shaft 32. In implementation, the flapping module 3 can be configured only on one side of the conveying module 2, and the flapping modules 3 can be configured on both sides of the conveying module 2. The flapping structures in the two flapping modules 3 can be arranged in an interlaced manner, such as Figure 2 As shown, in order to achieve a better flapping effect. In actual operation, the flapping structures in the two flapping modules 3 can perform flapping actions synchronously or staggeredly, depending on actual needs, and no examples are given here. As an example, in this embodiment, flapping modules 3 are respectively provided on both sides of the conveying module 2, and the two flapping modules 3 respectively include multiple flapping structures arranged in parallel, such as Figure 2 shown.

[0048] In some embodiments, a separate conveying motor can be configured for the conveying module 2, and at the same time, an independent flapping power 31 can be configured for the flapping structure. The conveying motor and the flapping power 31 can be connected to the control module (including a controller or a control circuit, etc.) respectively, so as to use the control module to control the conveying module 2 and the flapping module 3 to cooperate. In other embodiments, the conveying motor and the flapping power 31 can also be one power, that is, the conveying module 2 and the flapping module 3 share one power, and the power is respectively connected to the conveying module 2 and the flapping module 3 through the transmission mechanism, which can also achieve the purpose of controlling the conveying module 2 and the flapping module 3 to cooperate, and no more examples are given here.

[0049] In practice, the beating structure may include a connecting frame 33 and a cotton beating rack 34. Figures 2 - 4 As shown, the cotton beating rack 34 is fixed to the connecting frame 33, and one end of the connecting frame 33 is connected to the connecting shaft 32, so that the rotation of the connecting shaft 32 can drive the cotton beating rack 34 to swing, so that the cotton beating rack 34 can contact and beat the cotton wool products conveyed on the conveying module 2.

[0050] For ease of description, the portion below the cotton-beating paddle 34 for contacting the cotton lint product is referred to as the lower portion 341, the surrounding sides of the cotton-beating paddle 34 are referred to as the side portions 342, and the side above the cotton-beating paddle 34 away from the lower portion 341 is referred to as the upper portion 343. Figure 4 and Figure 5 shown.

[0051] The cotton-beating paddle 34 can be integrally in a long strip structure. During implementation, the cotton-beating paddle 34 can be realized by using the existing technology. For example, in one implementation manner, the cotton-beating paddle 34 can be constructed as a plate-like structure. Also, in some other implementation manners, the cotton-beating paddle 34 can be a combined structure composed of multiple beating rods 4 or beating strips, as Figures 3 - 5 shown.

[0052] In this embodiment, the beating structure further includes a protection part. The protection part includes a protective layer 61 covering the lower part 341 of the cotton-beating paddle 34, as Figure 7 and Figure 8 shown. The protective layer 61 is constructed as a net shape so as to contact the cotton flannel product by using the protective layer 61. Since the protective layer 61 is constructed as a net shape and is in a tension state, it can not only effectively increase the contact area between the cotton-beating paddle 34 and the cotton flannel product and avoid the problem of stress concentration, but also more evenly disperse the beating force by using the net-shaped protective layer 61, so that the beating force can act more evenly on the surface of the cotton flannel product, thereby effectively solving the problem that the surface of the cotton flannel product is easily damaged during the process of the cotton-beating paddle 34 beating and contacting the cotton flannel product, and playing a protective role.

[0053] During implementation, the protection part has multiple implementation manners. For example, in the first implementation manner, the protective layer 61 can be tensioned on the lower part 341 of the cotton-beating paddle 34 so as to isolate and protect the lower part 341 of the cotton-beating paddle 34, as Figure 7 and Figure 8 shown. At this time, the protective layer 61 can be pasted on the lower part 341 of the cotton-beating paddle 34, or can be fixed to the lower part 341 of the cotton-beating paddle 34 through fasteners 7 such as bolts and screws, so that during the beating process, the protective layer 61 is exactly located between the cotton-beating paddle 34 and the cotton flannel product.

[0054] Also, in the second implementation manner, the protection part further includes at least two restraint bands 63. The two ends of the restraint band 63 are respectively connected to both sides of the protective layer 61, and the restraint bands 63 are respectively arranged at intervals along the length direction of the protective layer 61. As an example, the restraint band 63 can be an elastic elastic band, as shown in FIGS. 9 and Figure 10 shown. The two ends of the elastic band are respectively connected to both sides of the protective layer 61 (both sides along the length direction of the protective layer 61). During assembly, each elastic band can be respectively sleeved on the cotton-beating paddle 34, so that the protective layer 61 can be firmly constrained and tensioned on the lower part 341 of the cotton-beating paddle 34. With such a design, the assembly and replacement process of the protection part is simpler.

[0055] As another example, the restraint strap 63 may include two sections, namely the first restraint strap and the second restraint strap. The first restraint strap and the second restraint strap may not be elastic. One end of the first restraint strap and the second restraint strap are respectively connected to both sides of the protective layer 61. When assembling the protection part, the first restraint strap and the second restraint strap in the same restraint strap 63 can respectively wind from the side part 342 of the cotton-beating paddle 34 to the upper part 343 of the cotton-beating paddle 34, and can be connected together by tying a knot, which can not only tension the protective layer 61, but also effectively prevent the protective layer 61 from falling off. Of course, in implementation, a connection structure may also be configured on the first restraint strap and / or the second restraint strap, so that the first restraint strap and the second restraint strap can be connected together through the connection structure, and the connection structure can be an existing connection buckle or the like.

[0056] In the third implementation manner, the protection part further includes a skirt 62 connected to the periphery of the protective layer 61. The skirt 62 is formed into a ring shape, as Figure 11 and Figure 12 shown, so that the protective layer 61 and the skirt 62 can jointly form a cap-shaped structure. During assembly, the skirt 62 can correspond to the side part 342 of the protection part. In implementation, the skirt 62 can be connected to the side part 342 of the cotton-beating paddle 34 by means of pasting, bolt connection or screw connection, etc., so as to achieve the purpose of fixing the protective layer 61 and keeping the protective layer 61 in a tensioned state. On this basis, if the restraint strap 63 needs to be configured, both ends of the restraint strap 63 can be respectively connected to the skirt 62, as Figure 11 and Figure 12 shown, so as to fix and tension the protective layer 61 by using the restraint strap 63. In implementation, the skirt 62 can be a mesh structure or a non-mesh structure. The skirt 62 can be made of the same material as the protective layer 61 or different, which can be determined according to actual needs.

[0057] In the fourth implementation manner, the protection part further includes a skirt 62 connected to the periphery of the protective layer 61. The skirt 62 is formed into a ring shape, so that the protection part forms a bag-shaped structure with an opening and adapted to the cotton-beating paddle 34, as Figure 13 and Figure 14 shown. When assembling or replacing the protection part, only need to insert the cotton-beating paddle 34 into the protection part from the opening, which is very convenient and efficient. In implementation, the material of the skirt 62 is preferably the same as that of the protective layer 61. For example, both the skirt 62 and the protective layer 61 can be constructed as a mesh, and the skirt 62 and the protective layer 61 can be an integral structure. In a further implementation manner, a ring-shaped elastic band 64 is further provided at the opening, as Figure 13 and Figure 14As shown, a circular elastic band 64 is used to automatically tighten the opening, making it easier to fix the protective layer 61 to the lower part 341 of the cotton-beating paddle 34, and more conducive to quickly tensioning the protective layer 61 to achieve a more uniform contact and beating effect. In addition, a tightening channel can be provided at the opening. The tightening channel has a notch, and a drawstring is arranged in the tightening channel. The two ends of the drawstring extend out of the tightening channel through the notch respectively, so that the opening can be tightened by tightening the drawstring, and further the purpose of fixing and tensioning the protective layer 61 can be achieved.

[0058] In implementation, the protective layer 61 can preferably adopt a mesh fabric, such as Figure 7 and Figure 8 shown. As a preference, the protective layer 61 can preferably adopt a mesh fiber mesh, which is more conducive to solving the problem that the surface of the down fabric is easily damaged during the beating contact.

[0059] Embodiment 2

[0060] The main difference between this Embodiment 2 and the above-mentioned embodiment is that in the cotton-beating machine provided in this embodiment, the cotton-beating paddle 34 includes a connecting component 5 and at least two paddle rods 4. Each paddle rod 4 is connected into a whole through the connecting component 5. The connecting component 5 can be used to position and restrict the paddle rods 4 so that there is a specific positional relationship between the paddle rods 4. For example, as Figures 3 - 4 shown, in this embodiment, the paddle rods 4 can be kept parallel to each other through the connecting component 5. The connecting frame 33 is fixedly connected to the connecting component 5, as Figure 3 shown.

[0061] In implementation, the number of paddle rods 4 in the cotton-beating paddle 34 can be determined according to actual needs. For example, as Figure 3 and Figure 4 shown, the cotton-beating paddle 34 is configured with four paddle rods 4, and the paddle rods 4 are round rods without edges and corners, so it is not easy to damage the surface of the cotton floss products during the beating process. Similarly, in implementation, the number of connecting components 5 in the cotton-beating paddle 34 can be determined according to actual needs. For example, as Figure 3 and Figure 4 shown, the cotton-beating paddle 34 is configured with six connecting components 5. The six connecting components 5 are evenly distributed along the length direction of the paddle rods 4 to more stably and reliably position and restrict each paddle rod 4 and keep each paddle rod 4 parallel to each other, which is more conducive to achieving a better and more efficient beating effect. At this time, the connecting frame 33 can be fixedly connected to at least two of the connecting components 5 to improve the connection strength and stiffness. And in implementation, the connecting frame 33 can be detachably connected to the connecting component 5 through fasteners 7 such as bolts or screws, as Figure 3 and Figure 4 shown, so as to separately disassemble the cotton-beating paddle 34 during later maintenance and repair.

[0062] During implementation, the connecting component 5 has a variety of implementation methods, and it only needs to be able to position and fix the racket bar 4. For example, in one implementation, the connecting component 5 may include an upper splint and a lower splint, and the upper splint and / or the lower splint are constructed with at least two positioning grooves adapted to the racket bar 4. At the same time, the upper splint is constructed with a first connecting hole, and the lower splint is constructed with a second connecting hole adapted to the first connecting hole. During assembly, each racket bar 4 is respectively arranged in the positioning groove, and the upper splint and the lower splint are fixed with fasteners 7 adapted to the first connecting hole and the second connecting hole, so that each racket bar 4 is respectively clamped between the upper splint and the lower splint, which is not only convenient for positioning and disassembly to accurately install and replace the racket bar 4, but also can stably constrain the racket bar 4, ensuring that each racket bar 4 has a relatively fixed position relationship, which is more conducive to achieving a better beating effect. During implementation, the fastener 7 can be adapted to the first connecting hole and the second connecting hole. For example, when at least one of the first connecting hole and the second connecting hole is a threaded hole, the fastener 7 can be a bolt adapted to the threaded hole. When the first connecting hole and the second connecting hole are both blind holes, the fastener 7 can be a bolt pair (including a bolt and a nut).

[0063] For example, in another embodiment, Figures 3 - 6 As shown, the connection assembly 5 may include a connection block 51 and a fastener 7. The connection block 51 is configured with an assembly groove 52 that passes through both sides. The assembly groove 52 includes an adapting hole 521 that passes through both sides of the connection block 51 and a connecting groove 522 that connects the two adapting holes 521. Figure 6 As shown, by machining the assembly groove 52, the rigidity of the upper end and / or lower end of the connection block 51 is greatly reduced, so that the connection block 51 at the assembly groove 52 can be deformed. Figure 5 and Figure 6 As shown, the upper and lower ends of the connecting groove 522 are respectively configured with a first locking hole 53 and a second locking hole that are adapted to each other, the first locking hole 53 and the second locking hole are respectively connected to the connecting groove 522, and the fastener 7 is adapted to the first locking hole 53 and the second locking hole. During assembly, the racket bar 4 passes through the adapting hole 521, and the fastener 7 is used to clamp the racket bar 4 in the adapting hole 521. In this embodiment, the connecting block 51 in the connecting assembly 5 is an integrated structure, which is not only convenient for processing and forming, but also makes the process of installing and removing the racket bar 4 simpler and more convenient. More importantly, it can effectively avoid the occurrence of sharp angles and acute angles in the structure, thereby effectively protecting the cotton wool products and preventing damage to the fabric surface of the cotton wool products. During implementation, the fastener 7 can be adapted to the first locking hole 53 and the second locking hole. For example, when at least one of the first locking hole 53 and the second locking hole is a threaded hole, the fastener 7 can be a bolt adapted to the threaded hole. When the first locking hole 53 and the second locking hole are both blind holes, the fastener 7 can be a bolt pair (including a bolt and a nut). In order to facilitate the connection of the connecting frame 33, the connecting block 51 is also configured with a mounting hole 511. Figure 3and Figure 4 as shown

[0064] In implementation, the number of the assembly grooves 52 can be one, two or more. For example, as Figure 5 and Figure 6 shown, the connecting block 51 is configured with two symmetrically arranged assembly grooves 52, so that the connecting block 51 can position and restrain four beating rods 4 at the same time. In implementation, the connecting block 51 can preferably be made of an aluminum alloy block.

[0065] In implementation, the material of the beating rod 4 can be determined according to actual requirements. For example, the beating rod 4 can be made of a bamboo rod, a wooden rod, a metal rod, a plastic rod, etc. In the preferred implementation provided in this embodiment, the beating rod 4 is made of a fiber rod, and can preferably be made of a glass fiber rod, a carbon fiber rod or an aramid fiber rod, etc. Compared with the above-mentioned beating rod 4, the fiber rod is more durable and has a longer service life. Moreover, the fiber rod has better elasticity and stronger resilience. On the one hand, it makes the beating effect better. On the other hand, it makes the noise during the beating process smaller. In addition, it can effectively reduce the impact on the connecting shaft 32 during the beating action process, and further reduce the impact on the beating power 31, so that the beating power 31 and the transmission mechanism between the beating power 31 and the cotton-beating paddle 34 can operate more stably and smoothly, effectively improving the service life of the equipment.

[0066] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model.
