Description

Technical Field

[0001] This utility model relates to the field of ceramic capacitor and varistor production, and in particular to a paper tape transfer device applied to a production line for ceramic capacitors and varistors. Background Technology

[0002] In the manufacturing process of capacitors or varistors, leads are typically arranged at equal intervals on a paper tape substrate first, and then the capacitor body or varistor is die-cast onto the leads. Therefore, the transfer of the paper tape substrate is a crucial step in the manufacturing process of capacitors or varistors.

[0003] In existing technologies, the technical solution disclosed in Chinese Utility Model Patent Application No. 202121252963.2, entitled "A Temperature Measuring Thermistor Lead Wire Forming Device," is generally as follows: the paper tape holder for placing the paper tape reel is set on one side of the worktable, the paper feeding mechanism is installed on the worktable next to the pressing mechanism, and a limiting roller is also provided on the feeding side of the paper feeding mechanism. After the paper tape is pulled out from the paper tape reel, it is fed into the pressing mechanism by the paper feeding mechanism through the limiting roller. This technology has the following technical problems in use: due to the relatively large distance between the paper feeding structure and the paper tape holder... In the process of transferring the paper tape, it is necessary to overcome not only the axial resistance of the paper tape reel, but also the gravity of the paper tape between the paper tape reel and the paper feeding mechanism, as well as the friction between the paper tape and the limiting roller. This requires a large pulling force to transfer the paper tape smoothly to the pressing mechanism, which causes the paper tape itself to generate a large tension. This makes the paper tape easily stretched and deformed, resulting in thinner thickness, poorer toughness, and insufficient tensile strength. This affects the fixation of the pins and can easily lead to frequent paper tape breakage in subsequent production processes of capacitors or varistors, causing frequent interruptions in the entire capacitor production process.

[0004] Given the above-mentioned shortcomings of the existing technology, the applicant believes it is necessary to make technical improvements to provide a paper feeding belt structure that effectively prevents the paper belt from being stretched and deformed, and provides a more stable paper feeding belt structure. Utility Model Content

[0005] The purpose of this invention is to solve the above-mentioned problems and shortcomings, and to provide a paper feeding structure for the production of ceramic capacitors and varistors. By setting a paper tape guide wheel mechanism at the upper end of the paper tape holder, the paper tape is moved forward by the drive wheel and the driven wheel rubbing the paper tape, thereby effectively reducing the tension formed on the paper tape during the transfer process, effectively preventing the paper tape from being stretched, deformed or broken, and thus improving the product quality of ceramic capacitors and varistors, and ensuring the smooth operation of the ceramic capacitor and varistor production line.

[0006] The technical solution of this utility model is implemented as follows: a paper feeding structure applied to the production of ceramic capacitors and varistors includes a workbench, a paper frame body disposed on one side of the workbench, and a paper belt guide wheel mechanism. The paper belt guide wheel mechanism consists of a motor, a driving wheel connected to the motor shaft, and a driven wheel. The characteristic is that the paper belt guide wheel mechanism is disposed at the upper end of the paper frame body. The driven wheel has baffles on both sides of its wheel edge. A paper feeding groove is formed between the two baffles and the peripheral surface of the driven wheel. Friction texture is also provided on the bottom of the paper feeding groove. The driving wheel is embedded in the paper feeding groove, and a paper belt passage gap is formed between the peripheral surface of the driving wheel and the friction texture.

[0007] Furthermore, the paper frame is composed of two cross supports stacked together, and a paper tape reel placement groove is formed between the two cross supports. A paper tape reel pin is provided at the center of the two cross supports. The inner ends of the two cross supports are fixedly connected to the workbench, and the outer sides of the two cross supports are formed with paper tape reel placement slots.

[0008] Furthermore, the paper tape guide wheel mechanism is located on the upper side of one of the two cross supports.

[0009] Furthermore, the upper and lower parts of the inner sides of the two cross supports are respectively provided with horizontal connecting rods that are connected to the workbench.

[0010] The beneficial effects of this utility model are:

[0011] Firstly, in this invention, a paper tape guide wheel mechanism is provided at the upper end of the paper feeder. The paper tape is drawn directly from the paper tape reel and enters the paper tape guide wheel mechanism. The distance between the paper tape reel and the paper tape guide wheel mechanism is very short, and no additional limiting rollers are needed between them. When the paper tape is transferred, it only needs to overcome the axial resistance when the paper tape reel rotates, without having to overcome the weight of the paper tape or the friction between the paper tape and the limiting rollers. Therefore, the resistance that needs to be overcome in the paper tape transfer in this application is small, and the tension formed on the paper tape during the transfer process is also very small. At the same time, the active wheel and the driven wheel are used to rub the paper tape, providing power for the forward movement of the paper tape, which greatly reduces the pulling of the paper tape by the subsequent processing mechanism, thereby effectively reducing the tension generated on the paper tape. Therefore, this invention can effectively prevent the paper tape from being stretched and deformed during the transfer process, which is conducive to improving the product quality of ceramic capacitors and varistors. It can also effectively avoid the occurrence of paper tape breakage, ensuring the smooth operation of the ceramic capacitor and varistor production line.

[0012] Secondly, the drive wheel is embedded in the paper feed groove of the driven wheel, which can effectively prevent the paper belt from deviating; at the same time, the friction texture can further increase the friction between the paper belt and the driven wheel, so that the drive wheel and the driven wheel generate a greater rubbing force on the paper belt, which helps to further reduce the pulling force on the paper belt in subsequent processes, making the tension on the paper belt smaller and less prone to deformation.

[0016] To enable those skilled in the art to better understand the technical solution of this utility model, the technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0017] like Figure 1 , 2 As shown in Figure 3, this utility model provides a paper feeding structure for the production of ceramic capacitors and varistors, including a workbench 1, a paper frame 2 disposed on one side of the workbench 1, and a paper belt guide wheel mechanism 3. The paper belt guide wheel mechanism 3 consists of a motor 31, a driving wheel 32 connected to the rotating shaft of the motor 31, and a driven wheel 33. In order to achieve the purpose proposed by this utility model, the paper belt guide wheel mechanism 3 is disposed at the upper end of the paper frame 2. The driven wheel 33 has baffles 331 on both sides of its wheel edge. A paper feeding groove 332 is formed between the two baffles 331 and the peripheral surface of the driven wheel 33. A friction texture 333 is also provided on the bottom of the paper feeding groove 332. The driving wheel 32 is embedded in the paper feeding groove 332, and a paper belt passage gap is formed between the peripheral surface of the driving wheel 32 and the friction texture 333. Since the paper tape guide wheel mechanism 3 is directly set at the upper end of the support body 2, after the paper tape 10 on the paper tape reel is pulled up, it directly enters the paper tape passage gap formed between the peripheral surface of the drive wheel 32 and the friction texture 333 on the paper tape guide wheel mechanism 3. Driven by the motor 31, the drive wheel 32 and the driven wheel 33 rub the paper tape 10 forward through friction, providing the main power for the forward movement of the paper tape 10. In this way, even if the subsequent process pulls the paper tape 10, only a small pulling force is needed, which can effectively prevent the paper tape 10 from being stretched, deformed or broken. The friction texture 333 can increase the friction between the paper tape 10 and the driven wheel 33 to prevent the driven wheel 33 from slipping, thereby ensuring the smooth movement of the paper tape 10.

[0018] like Figure 1 , 2 As shown, the paper tray body 2 is composed of two cross supports 21 stacked together, with a paper tape reel placement groove 22 formed between the two cross supports 21. A paper tape reel pin 23 is provided at the center of the two cross supports 21. The inner ends of the two cross supports 21 are fixedly connected to the worktable 1, and the outer sides of the two cross supports 21 form paper tape reel mounting slots 221. In this way, the paper tape reel can be conveniently placed on the tray body 2 through the paper tape reel mounting slots 221, and the paper tape reel can rotate on the tray body 2 through the paper tape reel pin 23 to output the paper tape.

[0019] like Figure 1 , 2 As shown, the paper tape guide wheel mechanism 3 is disposed on the upper side of one of the two cross supports 21. The paper tape guide wheel mechanism 3 is fixed to the upper side of one of the cross supports 21 by a mounting bracket 34, so that the driving wheel 32 and the driven wheel 33 are aligned with the paper tape reel placement groove 22, thereby allowing the paper tape 10 to enter the paper feed groove 332 naturally and smoothly, ensuring that the paper tape 10 will not deviate during the transfer process.

[0020] like Figure 1 , 2 As shown, the upper and lower parts of the inner sides of the two cross supports 21 are respectively provided with horizontal connecting rods 24 that are connected to the worktable 1. The horizontal connecting rods 24 can increase the force support points of the cross supports 21 on the side of the worktable 1, so that the cross supports 21 can be installed more stably on the side of the worktable 1; at the same time, the horizontal connecting rods 24 can also provide more limiting constraints on the paper tape reel, thereby preventing the paper tape reel from becoming skewed or the paper tape 10 from becoming loose.

[0021] like Figure 1 , 2 As shown, a photoelectric switch assembly 4 is also provided on the workbench 1 at the output end of the paper tape guide roller mechanism 3. This invention links the paper tape transfer with subsequent processes through the photoelectric switch assembly 4. On the one hand, it can provide the required length of paper tape 10 for subsequent processes with high precision; on the other hand, if a fault occurs in a subsequent process, it can promptly control the paper tape guide roller mechanism 3 to stop working, preventing paper tape from accumulating on the workbench 1. Furthermore, it can determine the remaining amount of paper tape on the paper tape reel, issuing an early warning to remind workers to replace the reel in time, preventing paper tape 10 supply interruption and ensuring continuous production.

[0022] like Figure 1 , 2As shown, the photoelectric switch assembly 4 consists of a mounting bracket 41, a crossbar 42 mounted on the mounting bracket 41, and a photoelectric switch 43 mounted on the crossbar 42. The mounting bracket 41 and the crossbar 42 are connected in an adjustable manner. This allows the position of the photoelectric switch 43 to be adjusted via the crossbar 42, thereby better monitoring the operation of the paper tape guide roller mechanism 3 and the remaining amount of paper tape on the paper tape reel, enabling more accurate judgments.
