Description

Technical Field

[0001] The utility model belongs to the technical field of resistor production, and in particular relates to an automatic casing machine. Background Art

[0002] After the production and processing of capacitors and resistors, in order to improve their performance, they usually need to be covered with a protective film on the outside. This film can not only effectively prevent the capacitors and resistors from being damaged in subsequent processes or during use, but also play the role of moisture-proof, explosion-proof, flame-retardant, dust-proof and insulating. In the traditional capacitor and resistor casing process, it is mainly completed by manual operation. This process usually includes the following steps: First, workers need to pick up the capacitors and resistors one by one, and then manually put the casing on the outside of the capacitor and resistor. Then, they usually need to use a hot air gun or oven to heat the casing to shrink it and tightly wrap it around the surface of the capacitor and resistor.

[0003] Manual casing often requires workers to have high operating skills and patience. At the same time, manual operation is not only time-consuming and labor-intensive, but also inefficient and difficult to meet the needs of large-scale production. Secondly, due to the subjectivity and variability of manual operation, the quality and consistency of the casing are often difficult to guarantee, and problems such as loose casing, misalignment or uneven shrinkage are prone to occur. In addition, manual operation also has safety hazards. For example, improper use of heat guns or ovens may cause accidents such as burns or fires. Utility Model Content

[0004] The purpose of the utility model is to provide an automatic casing machine to solve the problems mentioned in the background technology.

[0005] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0006] An automatic casing machine comprises a base, a conveyor belt mechanism is installed on the upper side of the base, a cutting mechanism is installed on the front side of the conveyor belt mechanism, a feeding mechanism is installed on the front side of the cutting mechanism, and a heating box is installed on the left side of the cutting mechanism;

[0010] The front diameter of the guide tube is larger than the rear diameter thereof.

[0011] A pressing and positioning assembly is installed between the cutting mechanism and the heating box. The pressing and positioning assembly includes an electric telescopic rod. A pressure plate is fixed to the rear side of the output end of the electric telescopic rod. A limiting plate matching the pressure plate is fixed to the upper side of the conveyor belt mechanism.

DETAILED DESCRIPTION

[0022] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0023] like Figure 1-5 As shown, an automatic casing machine comprises a base 1, a conveyor belt mechanism 2 is installed on the upper side of the base 1, a cutting mechanism is installed on the front side of the conveyor belt mechanism 2, a feeding mechanism is installed on the front side of the cutting mechanism, and a heating box 3 is installed on the left side of the cutting mechanism;

[0024] The cutting mechanism includes a slideway 4 which is symmetrically distributed on the left and right and fixedly connected to the base 1, a slider 5 which is symmetrically installed on the inner side of the slideway 4 and is slidably connected to the upper and lower sides, a cutter 6 is fixed on the side close to the two sliders 5, and the two cutters 6 are symmetrically distributed up and down, and a transmission assembly for driving the upper and lower cutters 6 to run synchronously is installed on both sides of the slider 5, and the transmission assembly includes a pinion 7, and the pinion 7 is rotatably connected to the middle part of the slideway 4, an upper rack 8 meshing with the pinion 7 is vertically fixed to the front side of the upper slider 5, and a lower rack 9 meshing with the pinion 7 is vertically fixed to the rear side of the lower slider 5, and a cylinder 10 fixedly connected to the base 1 is vertically installed on the upper side of the cutting mechanism, and the output end of the cylinder 10 is transmission-connected to the upper slider 5;

[0025] The feeding mechanism includes a rotating wheel 11 symmetrically distributed up and down, the rotating wheel 11 is rotatably connected to the base 1, guide tubes 12 fixed to the base 1 are installed on both the front and rear sides of the rotating wheel 11, and a transmission component driving the rotating wheel 11 to rotate is installed on the side.

[0026] When the utility model is in use, the film tube used for wrapping the capacitor resistor is inserted from the guide tube 12 on the front side, and passes through the guide tube 12 on the rear side through the rotating wheel 11. The conveyor belt mechanism 2 controls the left and right movement of the capacitor resistor. When the catheter is located at the rear side of the guide tube 12 on the rear side, the transmission component drives the rotating wheel 11 to rotate so that the film tube is sleeved on the outside of the capacitor resistor. At this time, the cylinder 10 is started, pushing the upper slider 5 and the upper cutter 6 to move downward. At the same time, through the transmission of the pinion 7, the upper rack 8 and the lower rack 9, the lower slider 5 and the lower cutter 6 are synchronously moved upward to achieve the cutting of the sleeve material. Subsequently, the conveyor belt mechanism 2 continues to operate, so that the capacitor resistor wrapped with the film tube on the outside moves to the heating box 3 for heating. The heating box 3 is a box body with a notch matching the catheter on the rear side and a heating wire installed on the inside, thereby realizing the heating, shrinking and shaping of the fully automatic sleeve.

[0027] Through the cooperation of the conveyor belt mechanism 2, the feeding mechanism, the cutting mechanism and the heating box 3, the sleeve machine can automatically sleeve the capacitor resistor with the film tube, thereby reducing the labor intensity of the staff and reducing the chance of direct contact with dangerous equipment and materials by the staff, improving work safety. At the same time, the cutter 6 that runs symmetrically up and down and the stable feeding mechanism ensure the uniform cutting and accurate transmission of the sleeve material, avoiding the errors that may be caused by manual operation, and avoiding material damage or waste due to human factors, further reducing the material cost, and ensuring the processing quality of the capacitor resistor.

[0028] The transmission assembly includes a motor 13 fixed to the base 1, the output end of the motor 13 is connected to one of the rotating wheels 11, and a large gear 14 connected to the rotating wheel 11 is rotatably mounted on the side of each rotating wheel 11, and the upper and lower large gears 14 are meshed with each other.

[0029] The front diameter of the guide tube 12 is larger than the rear diameter thereof.

[0030] The downwardly distributed large gear 14 enables the upper and lower rotating wheels 11 to synchronously run in the opposite direction while also making the structure of the transmission assembly simple and reliable, thereby facilitating daily cleaning, maintenance and troubleshooting for users.

[0031] The front diameter of the guide tube 12 is larger than the rear diameter, which makes it easier for the film tube to pass through from the front. At the same time, the rear guide tube 12 can cooperate with the rotating wheel 11 to move the film tube forward and then rotate backward after the film tube is cut, thereby preventing the film tube from being flattened by the cutter 6, restoring its roundness, and improving the operating stability of the feeding mechanism.

[0032] A pressing and positioning assembly is installed between the cutting mechanism and the heating box 3, and the pressing and positioning assembly includes an electric telescopic rod 15, a pressing plate 16 is fixed to the rear side of the output end of the electric telescopic rod 15, and a limiting plate 17 matching the pressing plate 16 is fixed to the upper side of the conveyor belt mechanism 2.

[0033] The electric telescopic rod 15 and the pressure plate 16 can push the membrane tube sleeved on the outside of the capacitor and resistor backward, and cooperate with the limit plate 17 to move the membrane tube to a specified position, thereby further improving the processing accuracy and the product quality of the capacitor and resistor.

[0034] A lower slide bar 18 is fixed to the lower side of the upper rack, an upper slide bar 19 is fixed to the upper side of the lower rack, a lower buckle 20 slidably connected to the upper slide bar 19 is fixed to the side of the lower slider 5, and an upper buckle 21 slidably connected to the upper slide bar 19 is fixed to the side of the upper slider 5.

[0035] The cooperation between the upper slide bar 19 and the lower buckle 20 and the lower slide bar 18 and the upper buckle 21 is used to keep the front-to-rear position between the upper and lower racks 9 relatively stable, thereby ensuring the load-bearing capacity and reliability of the transmission assembly.

[0036] A hard spring 22 is fixedly connected between the upper slider 5 and the output end of the cylinder 10 .

[0037] The hard spring 22 is connected between the upper slider 5 and the output end of the cylinder 10 to buffer the impact force of the cylinder 10, thereby protecting the cutter 6 and the slider 5 and extending their service life.

[0038] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention.
