Description

Technical Field

[0001] The utility model belongs to the technical field of cotton quilt production, and particularly provides an efficient cotton patting device and a cotton patting machine. Background Art

[0002] In the production process of soft products such as cotton quilts and warm clothing, fillers such as down and cotton are filled to provide a warming effect. Since the fillers are unevenly filled in the soft products, it is necessary to pat and arrange them to make the fillers evenly distributed in the soft products. Traditionally, manual tools are used to pat and arrange the soft products. Due to the high labor intensity and low production efficiency of manual tool patting and arranging, some factories currently use automated cotton patting machines for cotton patting operations.

[0003] However, in existing production, the cotton patting machines generally use plastic plates or aluminum alloy plates as the cotton patting and hitting structures. Although the plate structure has a good patting area, when patting the thinner filling area of the soft product, the cotton patting device of the plate structure collides rigidly with the platform, which is prone to damage. At the same time, the connection part between the cotton patting device and the rotating shaft is also prone to fatigue damage due to the reaction force and vibration; when patting the thicker filling area, the gas resistance in the filler is too large, and it is not easy to pat the filler apart. Therefore, there is an urgent need for a cotton patting device and a cotton patting machine with better patting effect and longer service life. Summary of the Utility Model

[0004] The utility model provides an efficient cotton patting device and a cotton patting machine using the cotton patting device to solve the problems of short working life and poor patting effect of the cotton patting machine in the prior art.

[0005] The technical solution of the utility model is as follows:

[0006] An efficient cotton patting device includes a connecting buckle and at least two parallel fiber rods. The connecting buckle is used to position and restrain the fiber rods, and each fiber rod is connected into a whole through the connecting buckle.

[0007] In this solution, the fiber rod is used as the cotton patting and hitting structure to contact the target soft product. The rod-shaped contact surface is small, and the air discharge path in the filler at the patting position is short, which can quickly and fully discharge the air in the filler at the patting position, thereby reducing the resistance during patting and making it easier for the filler in the soft product to spread; the fiber rod has good resilience and flexibility. After patting the soft product, it can undergo a certain elastic deformation to buffer the reaction force and can quickly return to its original state, and will not be deformed and damaged like plastic materials; at the same time, the fiber rod is lighter in texture, and the force required to drive the fiber rod to rotate is not too large, and the force driving the fiber rod to rotate will not be too large, and there will be no situation where the cotton patting and hitting structure collides with the platform and is damaged like using metal materials. At least two parallel fiber rods, preferably 4 parallel fiber rods, can increase the effective area that the cotton patting device can pat, thereby increasing the patting rate.

[0008] Preferably, the fiber rod is a round rod. By setting the fiber rod as a round rod, while further reducing the hitting contact area, its symmetrical cross-section exhibits isotropic mechanical properties when bearing pressure and torsion. It can withstand forces evenly from any direction and is not prone to stress concentration points, which can greatly improve the service life of the fiber rod.

[0009] Preferably, the fiber rod is made of a glass fiber rod, a carbon fiber rod or an aramid fiber rod. It is preferably a glass fiber rod, which is lightweight and high-strength while having a simple molding process and lower cost.

[0010] Preferably, a plurality of connecting buckles are arranged along the length direction of the fiber rod. The plurality of connecting buckles fix the fiber rods to ensure the stability between the fiber rods, thereby ensuring the strength of the cotton-beating paddle composed of the fiber rods and preventing the fiber rods from deflecting due to excessive force during beating and affecting the beating effect.

[0011] Preferably, a plurality of mounting holes for passing through the fiber rod are provided on the connecting buckle. The fiber rod is connected to the connecting buckle through the mounting holes provided in the connecting buckle, and positioning and restraint are achieved through the tightening of the mounting holes.

[0012] Preferably, the mounting holes are arranged in pairs, and a through groove is provided between the paired mounting holes. By controlling the distance between the upper part and the lower part of the through groove, the scaling of the mounting holes is controlled. By controlling the distance between the upper part and the lower part of the through groove, the locking of the two mounting holes on the fiber rod can be directly controlled, and the fiber rod can be more conveniently fixed and positioned, realizing the rapid installation and replacement of the cotton-beating structure.

[0013] Preferably, a first concave part with an opening downward is provided at the upper part of the through groove, and a second concave part is provided below the connecting buckle between each pair of mounting holes.

[0014] In this solution, the setting of the first concave part can reduce the thickness of the upper part of the through groove, reduce the stiffness and improve the deformation ability of the upper part. When there are multiple pairs of mounting holes in a connecting buckle, a convex part is naturally formed between each pair of mounting holes. This convex part can strengthen the strength of the connecting buckle and can also better transmit force; while setting the second concave part can reduce the weight of the connecting buckle and also prevent the strip-shaped bottom surface formed by the connecting buckle from affecting the beating effect of the fiber rod.

[0015] Preferably, it further includes a connecting plate, which is used to mount the cotton-beating paddle on the cotton-beating machine, and the connecting plate connects at least two connecting buckles.

[0016] In this scheme, the cotton racket formed by the fiber rod is achieved by the reciprocating rotation of the transmission shaft to achieve circular beating, and moves with the transmission shaft as the axis. Since the fiber rod has a certain length and toughness, it is inevitable that the fiber rod will produce a certain bending deformation when it rotates rapidly. The closer to the direction of the rotating shaft, the greater the torque it receives. The connecting plate connects multiple connecting buckles to provide the fiber rod with multiple support points, and can transmit the torque to the connecting plate, thereby avoiding fatigue damage to the end of the fiber rod close to the rotating shaft due to long-term rotation, thereby improving the overall service life of the device.

[0017] A cotton beating machine comprises any one of the above-mentioned high-efficiency cotton beating rackets, and also comprises a frame and a driving motor, a transmission shaft and a material table arranged in the frame, the driving motor is drivingly connected to the transmission shaft, the cotton beating racket is drivingly connected to the transmission shaft through the connecting plate, the driving motor drives the transmission shaft to rotate, so that the cotton beating racket beats the soft products on the material table.

[0018] The motor drives the transmission shaft to rotate back and forth, and the transmission shaft drives the fiber rod to rotate and beat the soft cotton product. The cotton beating machine adopts the above-mentioned cotton beating paddle, which can make the filling material spread better during the cotton beating process and has a good beating effect. At the same time, the cotton beating structure composed of the fiber rod has a longer service life.

[0019] Preferably, the transmission shaft is arranged on both sides of the material platform, and the cotton beating paddles are arranged alternately along the length direction of the material platform, so as to increase the frequency of the cotton beating machine beating the soft products, thereby improving the beating efficiency.

[0020] Beneficial effects of the utility model:

[0021] When using the cotton-beating paddle provided by the utility model, the fiber rod serves as a cotton-beating striking structure in contact with the target soft product, the rod-shaped contact surface is small, and the air discharge path in the filler at the beating position is short, so that the air in the filler at the beating position can be quickly and fully discharged, thereby reducing the resistance during beating and facilitating the diffusion of the filler in the soft product; the fiber rod has good resilience and flexibility, and after beating the soft product, it can undergo a certain elastic deformation to buffer the reaction force and can quickly return to its original state; at the same time, the fiber rod is lighter in texture, and the force to drive the fiber rod to rotate does not need to be too large, which avoids the situation where the fiber rod collides with the platform and is damaged, and can greatly improve the service life of the equipment.

[0029] Combined with the drawings, through the specific implementation manners of the embodiments of the present invention, the technical solutions of the present invention are clearly and completely described.

[0030] Embodiment 1:

[0031] As Figures 1 to 2 shown, a highly efficient cotton - patting device includes a connecting plate 3 and a fiber rod 4. The connecting plate 3 connects the fiber rod 4 and the transmission shaft 2, and the driving motor 1 is in transmission connection with the transmission shaft 2. The fiber rod 4 is a round rod, and at least two are arranged in parallel. In this embodiment, preferably 4 fiber rods 4 are arranged in parallel to increase the effective range that the cotton - patting device can pat, thereby increasing the patting speed. And the fiber rod 4 includes, but is not limited to, carbon fiber rods 4, aramid fiber rods 4, glass fiber rods 4, etc. Preferably, glass fiber rods 4 are used. Glass fiber rods 4 are light in weight and high in strength, and the forming process is simple with low cost.

[0032] Specifically, taking the fiber rod 4 as the cotton - patting and hitting structure to contact the target soft and flexible product, the rod - shaped contact surface is small, and the path for the air in the filler at the patting position to be discharged is short, which can quickly and fully discharge the air in the filler at the patting position, thereby reducing the resistance during patting and making it more convenient for the filler in the soft and flexible product to spread; the fiber rod 4 has good resilience and flexibility. After patting the soft and flexible product, it can undergo a certain elastic deformation to buffer the reaction force and can quickly return to its original state, and will not be deformed and damaged like plastic materials; at the same time, the fiber rod 4 is lighter in texture, and the force required to drive the fiber rod 4 to rotate is not too large, and there will be no situation where the cotton - patting and hitting structure collides with the platform and is damaged as in the case of using metal materials.

[0033] Furthermore, the parallel fiber rods 4 are connected by connection buckles, and the connection buckles fix the fiber rods 4 through a hoop structure. Specifically, multiple mounting holes for threading the fiber rods 4 are provided on the connection buckle 7. The mounting holes are arranged in pairs, and a through groove 73 is provided between the side walls of the paired mounting holes. By setting a locking mechanism in the through groove 73 to control the distance between the upper and lower parts of the through groove 73, the fiber rods 4 can be easily fixed and positioned, realizing the rapid installation and replacement of the cotton-beating paddle. At the same time, connection buckles are provided at least at the head and tail of the fiber rods 4, and 4 fiber rods 4 are connected by the connection buckles. In this embodiment, in addition to the connection buckles provided at the head and tail, 4 connection buckles are also evenly arranged at the middle positions of the fiber rods 4. The multiple connection buckles fix the fiber rods 4 to ensure the stability between the fiber rods 4, and further ensure the strength of the cotton-beating paddle composed of the fiber rods 4, avoiding the fiber rods 4 from deflecting due to excessive force during beating and affecting the beating effect.

[0034] Furthermore, as Figure 3 shown, a first concave portion 71 with a downward opening is provided in the upper part of the through groove 73 in the connection buckle 7, and a second concave portion 72 is provided below the connection buckle 7 between each pair of mounting holes.

[0035] In this solution, the setting of the first concave portion 71 can reduce the thickness of the upper part of the through groove 73, improve the deformation ability of the structure, and facilitate the locking piece to lock the mounting hole. When multiple pairs of mounting holes are provided in one connection buckle 7, a convex portion is naturally formed between each pair of mounting holes. This convex portion can strengthen the strength of the connection buckle, and through connection with the connecting plate 3, it can also better transmit the force on the connecting plate 3. By setting the second concave portion 72, while reducing the weight of the connection buckle 7, it also avoids the strip-shaped bottom surface formed by the connection buckle 7 from affecting the beating effect of the fiber rod 4. And connection holes can be provided on the upper surface of the connection buckle for bolt connection with the connecting plate 3, and the connecting plate 3 is connected to at least two of the connection buckles in the length direction. In this solution, it is preferably to connect 3 connection buckles.

[0036] Specifically, since the cotton-beating paddle formed by the fiber rods 4 realizes circular beating through the reciprocating rotation of the transmission shaft and moves with the transmission shaft as the axis, due to the certain length and toughness of the fiber rods 4, when rotating rapidly, the fiber rods 4 will inevitably generate a certain amount of bending deformation. The closer to the axis of the rotating shaft, the greater the torque received. The connecting plate 3 connects multiple connection buckles, enabling the fiber rods 4 to have multiple support points and transmitting the torque to the connecting plate 3, avoiding fatigue damage at the end close to the rotating shaft due to the long-term rotation of the fiber rods 4 and improving the overall service life of the device.

[0037] Even further, the cross-section of the connecting plate 3 is T-shaped. Specifically, the connecting plate 3 is a structure formed by welding and stacking aluminum alloy pipes and steel into a triangular shape on the side, enabling the connecting plate 3 to better bear the force and thus improving the service life.

[0038] Further, as Figure 3 shown, the transmission shaft 2 is a multi-prism, and a hoop structure adapted to the edge of the transmission shaft 2 is provided on the connecting plate 3. The transmission shaft is prism-shaped, which can drive the connecting plate 3 to rotate better during rotation. At the same time, the hoop structure can conveniently control the position of the connecting plate 3 on the transmission shaft, thereby regulating the interval between the cotton-beating pats to adapt to the soft products under different beating conditions.

[0039] Embodiment 2:

[0040] As Figure 4 shown, a cotton-beating machine includes the efficient cotton-beating pat described in Embodiment 1, and further includes a driving motor 1, a transmission shaft 2, a frame 5 and a material table 6. The material table 6 can be a conveyor belt platform, and the soft product to be beaten is fed through the feeding port, or a flat workbench can be directly used to directly weave the soft product. By using the above-mentioned cotton-beating pat, the cotton-beating machine can make the filler better spread during the cotton-beating process, and has a good beating effect. At the same time, the cotton-beating and hitting structure composed of the fiber rods 4 has a higher service life.

[0041] Further, the transmission shaft 2 is arranged on the side of the material table 6, and the cotton-beating pats are uniformly arranged along the length direction of the transmission shaft, or the transmission shaft 2 is arranged on both sides of the material table, and the cotton-beating pats are arranged alternately on both sides of the material table 6. Thereby, the frequency of the cotton-beating machine for beating the soft product is increased, and the beating efficiency is improved.

[0042] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of protection required by the present invention.
