Description

Technical Field

[0001] The invention belongs to the technical field of mechanical design, and in particular relates to a transmission and transfer device for blades of an accordion bag inner liner. Background Art

[0002] When producing accordion bags, the inner blades need to be introduced into the special assembly machine for accordion bag production in a certain order. With the cooperation of the introduction device, the transfer device can be used to achieve the uninterrupted and uniform introduction of multiple groups of accordion bag inner blades into the assembly machine to ensure the production efficiency of the accordion bag.

[0003] Currently, there is little research and development on the transmission and transfer device for the accordion bag inner blades. The assembly line introduction operation is completely performed manually, and there are mainly the following technical difficulties: First, the inner blade groove of the combination machine is too narrow, making it difficult to accurately transmit and introduce the inner blades, resulting in wrinkles and even deviations in the accordion bag inner blades during the introduction process; second, the manual introduction method is too inefficient and cannot meet modern production needs. Summary of the invention

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a transmission and transfer device for the inner blades of an accordion bag, so as to at least partially solve the problems raised in the above background technology.

[0005] The present invention comprises an inner liner blade introduction unit, a frame structure for fixing the inner liner blade introduction unit, and an opening and closing unit located below the inner liner blade introduction unit;

[0006] There are a plurality of liner blade introduction units, which are evenly arranged in the frame structure; each liner blade introduction unit is V-shaped and is used to constrain the liner blades;

[0007] The lower end of the inner liner blade introduction unit is provided with an open opening to constrain the regular inner liner blades to fall from the open opening;

[0008] The opening is directly opposite to the opening and closing unit. When the opening and closing unit is opened, all the inner liner blades fall into the external assembly machine at the same time and at a uniform speed.

[0009] Through the above improvements, the transmission and transfer device of the accordion bag inner blade of the present invention can transmit and transfer the blade more efficiently and stably. The coordinated work of various components realizes the automatic transmission and transfer of the inner blade, improving production efficiency and product quality. The design of the transmission device takes into account the shape and transmission path of the inner blade, ensuring that the inner blade can smoothly and continuously pass through each transmission link, thereby improving the efficiency and stability of the transmission.

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0018] It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to directions in the drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively. The use of these directional terms is to facilitate the description and understanding of the embodiments of the present invention and should not be regarded as limiting the scope of protection of the present invention. In addition, the embodiments of the present invention can be modified and changed in various ways without departing from the spirit and scope of the present invention, and these modifications and changes should also be regarded as the scope of protection of the present invention.

[0019] This embodiment is a technical improvement made to address the technical problem that the inner liner blade groove of the combined machine is too narrow, making it difficult to accurately transmit and introduce the inner liner blades, which leads to wrinkles and even deviations in the accordion bag inner liner blades during the introduction process. Through in-depth analysis and research on the prior art, the present invention proposes a new solution, which aims to improve the transmission accuracy and stability of the inner liner blades and reduce various problems that may arise in the production process. Specifically, the present invention designs a special transmission transfer device so that the inner liner blades can remain stable and accurate during the introduction process, thereby avoiding wrinkles and deviations caused by improper introduction. This technical improvement not only improves production efficiency, but also greatly reduces the scrap rate, and has significant economic benefits and practical value.

[0020] The present invention provides a transmission and transfer device for liner blades of an accordion bag, which is applied to the production of accordion bags, and comprises an liner blade introduction unit, a frame structure for fixing the liner blade introduction unit, and an opening and closing unit located below the liner blade introduction unit;

[0021] There are a plurality of liner blade introduction units, which are evenly arranged in the frame structure; each liner blade introduction unit is V-shaped and is used to constrain the liner blades;

[0022] The lower end of the inner liner blade introduction unit is provided with an open opening to constrain the regular inner liner blades to fall from the open opening;

[0023] The opening is directly opposite to the opening and closing unit. When the opening and closing unit is opened, all the inner liner blades fall into the external assembly machine at the same time and at a uniform speed.

[0024] In some embodiments, the liner blade introduction unit is composed of two introduction plates, each of which has evenly distributed elliptical through holes in the middle to reduce the mass of the introduction plate; each of the introduction plates has equidistant circular through holes on both sides, and carbon fiber tubes are passed through the circular through holes to prevent skewing during the introduction process of the liner blades.

[0025] In one example, if Figure 1 and Figure 2 As shown, there are 12 groups of liner blade introduction units, each introduction plate 1 has evenly arranged elliptical through holes 8 in the middle, and equidistant circular through holes 9 on both sides; the 12 groups of V-shaped liner blade introduction units are provided with fixed plates 7 without through holes at the head and tail ends. Through this design, the V-shaped liner blade introduction unit can effectively guide the blades into the transmission path, avoiding wrinkles or offsets caused by improper angles. The design of the introduction plate allows liner blades of different shapes and sizes to pass smoothly, and this feature greatly improves the adaptability of the production line.

[0026] Furthermore, the elliptical through holes can reduce the overall weight of the device and can reduce the electrostatic adsorption effect of the accordion bag inner blade 19 on the introduction plate; the circular through holes on the left and right sides pass through a hollow carbon fiber tube with a diameter of 5mm, the center of the carbon fiber tube is 10mm away from the side of the introduction plate, and the center distance of the upper and lower carbon fiber tubes is also 10mm apart. There are a total of 6 tubes distributed on both sides of the introduction plate, which can effectively avoid the lateral deviation and skewness of the accordion bag inner blade. The carbon fiber tube has the advantages of high strength, long life, corrosion resistance, light weight, low density, etc., and it has appropriate rigidity and is not easy to bend during the installation of this device. Through this design, the carbon fiber tube can not only effectively support and guide the blades, but also reduce electrostatic adsorption and friction, and improve transmission efficiency and stability. The non-through-hole fixing plates at the head and tail ensure the stability of the introduction plate and prevent the blades from being offset or falling off due to external factors such as wind during the transmission process.

[0027] In one example, if Figure 3 , Figure 4 and Figure 5 As shown, the introduction plates are connected through the grooves of the L-shaped fixing plates on both sides (the frame structure is formed by the left L-shaped fixing plate 2 and the right L-shaped fixing plate 3), and an open opening is set on the lower side of each pair of introduction plates in the inner liner blade introduction unit. The lower side of the open opening faces two introduction rubber rollers, which are the active introduction rubber roller 13 and the driven introduction rubber roller 14. The two constitute the opening and closing unit. The introduction rubber rollers can effectively transmit the blades. The active introduction rubber rollers provide power, and the driven introduction rubber rollers assist in transmission, ensuring the stability and continuity of the blades during transmission. The coordinated use of the active introduction rubber rollers and the driven introduction rubber rollers improves the efficiency and stability of the transmission device.

[0028] Furthermore, synchronous wheels 10 are installed on both sides of the active introduction rubber roller, which are fixed by synchronous belts 12. Driven rubber roller fixing rods 16 are installed at both ends of the introduction rubber roller. The driven rubber roller fixing rods are assisted in displacement by cylinders 4 on both sides (i.e., the first power source). The driven rubber roller fixing rods are limited by guide rails 17 and sliders 18, that is, both ends of the driven rubber roller fixing rods are limited to the guide rails by sliders, and the synchronous belt is connected to the drive motor 11 (i.e., the second power source) at the end. Through this design, the introduction plate can stably guide the blades into the transmission path, and the active introduction rubber roller is driven by the synchronous wheel and the synchronous belt to achieve smooth transmission of the blades. The design of the movable slide rail and cylinder allows the blades to be adjusted in position as needed during the transmission process to ensure the accuracy and stability of the transmission.

[0029] Furthermore, the active introduction rubber roller passes through the bearing holes of the left L-shaped fixing plate and the right L-shaped fixing plate, and is connected by bearings. The active introduction rubber roller can achieve smooth transmission of the blades through the transmission of the bearings and the synchronous wheel. The design of the bearings reduces the friction and resistance during the transmission process, and improves the transmission efficiency and stability.

[0030] Furthermore, the two ends of the driven import rubber roller are fixed to the driven rubber roller fixing rod through bearings. With this design, the driven import rubber roller can realize the smooth transmission of the blades through the connection between the bearing and the fixing rod. The design of the bearing reduces the friction and resistance during the transmission process, and improves the transmission efficiency and stability. The design of the fixing rod ensures the stability and strength of the driven import rubber roller, and prevents the blades from being offset or falling off during the transmission process.

[0031] Furthermore, the driven rubber roller fixing rod is fixed on the slider, the slider is mounted on the guide rail, and the guide rail is mounted on the lower side of the L-shaped fixing plate; the end of the driven rubber roller fixing rod is installed with a cylinder. Through this design, the driven rubber roller fixing rod can realize the smooth transmission of the blades through the connection of the slider and the guide rail. The design of the cylinder assists the movement of the blades to ensure the accuracy and stability of the transmission. The design of the slider and the guide rail reduces the friction and resistance during the transmission process and improves the transmission efficiency and stability.

[0032] In one example, if Figure 4 As shown, the driving motor is connected to the right L-shaped fixing plate through a sleeve 15; a synchronous wheel is installed at the end of the motor shaft, and is connected to the synchronous wheel at the end of the active rubber roller close to the motor through a synchronous belt.

[0033] Furthermore, on one side of the synchronous wheel and the connecting plate 5, except for the synchronous wheel connected to the motor end and the L-shaped fixing plate near the motor end, the rest are connected in pairs through synchronous wheels in sequence, and the last synchronous wheel is not connected; on the other side, from left to right, the synchronous wheels are connected in pairs by synchronous belts in sequence, and there is no spare synchronous wheel. Through this design, the synchronous wheel and the synchronous belt can realize the synchronous transmission of the blades, ensuring the smoothness and continuity of the transmission process. The design of the synchronous wheel and the synchronous belt reduces the friction and resistance in the transmission process and improves the transmission efficiency and stability.

[0034] In certain embodiments, such as Figure 1 As shown, the introduction plate is fixed by the grooves of the left and right fixing plates, and the left L-shaped fixing plate portion corresponding to the middle of the two sides of the introduction plate is hollowed out, and the right L-shaped introduction plate has mesh-shaped connection plate holes; the L-shaped fixing plates on both sides are connected and fixed by four connecting rods 6. Through this design, the introduction plate can be firmly fixed on the L-shaped fixing plate to ensure the stability of the blade during the transmission process. The hollowing process and the connection plate hole design reduce the weight of the fixing plate and improve the overall efficiency and stability of the transmission device.

[0035] Further, the lower side of the L-shaped fixing plate is provided with holes for installing bearings and connecting guide rails. Through this design, the L-shaped fixing plate can conveniently install bearings and guide rails to ensure the smooth operation of the introduction rubber roller and the slide rail.

[0036] Furthermore, the connecting plate is connected to the right L-shaped fixing plate through the sleeve, and is used to mount the transmission transfer device to the next step of the assembly equipment; wherein the connecting plate is hollowed out. Through this design, the connecting plate can achieve smooth transmission of the blades through the connection of the sleeve and the L-shaped fixing plate. The hollowing design reduces the weight of the connecting plate and improves the overall efficiency and stability of the transmission device. The design of the connecting plate ensures the stability and strength of the transmission device and prevents the blades from being offset or falling off during the transmission process.

[0037] Furthermore, the driving motor is a worm gear encoder reduction motor. Through this design, the worm gear encoder reduction motor can provide stable transmission power to ensure the smooth transmission of the blades. The design of the reduction motor improves the transmission accuracy and stability of the transmission device and reduces errors and damage during the transmission process. The design of the encoder can monitor the speed and position during the transmission process in real time to ensure the accuracy and stability of the transmission.

[0038] In summary, the device realizes the automatic transmission and transfer of blades through the coordinated work of various components. The V-shaped inlet plate is used to guide the blades into the transmission path, the L-shaped fixing plate is used to fix and support various components, the active inlet rubber roller and the driven inlet rubber roller are used to transmit the blades, the drive motor provides power, and the booster cylinder assists the driven rubber roller fixing rod to move in a directional manner, thereby controlling the opening and closing of the active and driven rubber rollers, and the synchronous wheel and synchronous belt are used for transmission and synchronous control.

[0039] Working process of this device: When the 12 liner blades are introduced, this device will be transferred to the top of the assembly machine, so that it is located 5mm away from the highest point of the assembly machine, and the width of the active introduction rubber roller and the driven introduction rubber roller at the lower side of the transfer device when they are separated is consistent with the opening of the assembly machine, so that it can be smoothly introduced. When this device reaches the specified position, the cylinder is set, and the driven rubber roller fixing rods on the left and right sides move to a certain position through the slider on the guide rail, so that the active introduction rubber roller and the driven introduction rubber roller are in a separated state, see Figure 5 And it is closely attached to the active introduction rubber roller on the other side, ensuring that the blade is always in a stable state during the transmission process, reducing the friction and resistance during the transmission process, and improving the transmission efficiency and stability.

[0040] When the active introduction rubber roller and the driven introduction rubber roller are in a separated state, the driving motor drives the synchronous wheel connected to it through the synchronous belt, and then drives the active introduction rubber roller, so that the active introduction rubber roller and the driven introduction rubber roller rotate in the direction of the accordion bag inner liner blade falling, helping it to simultaneously introduce 12 blades into the assembly machine at a uniform speed. The connecting plate is connected to the right L-shaped fixing plate through a sleeve, and the connecting plate is connected to an external mobile device to drive the device.

[0041] In the process of transmitting and introducing the inner blades of the accordion bag, the present invention uses the cylinder of the device and the active introduction rubber roller and the driven introduction rubber roller in coordination to ensure that the inner blades fall safely into the assembly machine. During the transmission process, the cylinder is always in the initial position, the active introduction rubber roller and the driven introduction rubber roller are in a close contact state, and the drive motor is in a non-powered state, thereby avoiding the defect of the inner blades of the accordion bag falling directly. Through this design, it is possible to effectively prevent the blades from being offset or falling during the transmission process, thereby improving the accuracy and stability of the transmission.
