Mosquito-repellent incense clamping and barrel loading mechanism

Abstract

This invention relates to a mosquito coil clamping and loading mechanism, comprising a mounting plate, multiple clamping blocks disposed below the mounting plate, and a drive mechanism. The clamping blocks are mounted on the mounting plate via a guide mechanism. The drive mechanism includes at least two drive wheels rotatably mounted on the mounting plate, a drive belt sleeved on the drive wheels, and a power source capable of driving the drive wheels to rotate forward and backward. The clamping blocks are fixedly connected to the drive belt. Using the technical solution of this invention, the power source drives the drive wheels to rotate forward and backward. The rotation of the drive belt is converted into the clamping blocks synchronously moving towards the center of the mounting plate to achieve a clamping action or moving away from the center of the mounting plate to achieve a release action. Because the speed of the forward and reverse rotation of the drive wheels is easily controlled, the drive belt can rotate smoothly, thereby making the movement accuracy of the clamping blocks more controllable. Since the clamping blocks can move towards or away from each other, synchronously clamping the periphery of the product, the product can fall more neatly into the container after release, reducing the risk of product damage.

Description

Technical Field

[0001] This invention relates to a mosquito coil clamp holding mechanism, belonging to the field of mosquito coil packaging machine equipment. Background Technology

[0002] After production and processing, mosquito coils are typically packaged in a tray using a moisture-proof film or bag to prevent surface moisture. The trays are then placed into mosquito coil containers, thus completing the packaging process. Traditionally, the trays are manually packed into containers. This manual method is labor-intensive, costly, and inefficient, making it unsuitable for automated production lines.

[0003] To this end, Chinese invention patent application CN115959337A, entitled "An Automatic Incense Coil Barrel Filling Device," discloses an automatic incense coil barrel filling device, including a frame. An incense tray and a barrel tray are fixedly installed on the frame. The incense tray is located above the barrel tray and has an incense coil feeding port and an incense coil discharge hole. The barrel tray has a barrel feeding port and a barrel discharge port. The frame also includes a feeding mechanism and a pressing mechanism driven by a drive device. An incense coil feeding mechanism is located at the incense coil feeding port on the frame, a barrel feeding mechanism is located at the barrel feeding port on the frame, a pressing mechanism is located at the corresponding position of the incense coil discharge hole, and a barrel discharging mechanism is located at the barrel discharging port on the frame. The incense coil feeding mechanism, the barrel feeding mechanism, the pressing mechanism, and the barrel discharging mechanism are arranged sequentially along the circumference of the frame. This patent uses a feeding mechanism to feed mosquito coils into the mosquito coil container. However, this method has several problems: if the container is deep, the mosquito coil is more likely to break when it falls; if the container opening is too small or deformed, the mosquito coil is difficult to feed into the container, requiring high precision; or if the mosquito coil is tilted or even stuck at the opening after being fed into the container, the risk of damage is high when the coil is pressed into the container by the pressing mechanism.

[0004] In Chinese invention patent application CN119929263A, entitled "A Mosquito Coil Loading Production Line and Its Working Method," the mosquito coil loading production line includes a first support frame, a second support frame, a first conveying device disposed on the first support frame, and a second conveying device disposed on the second support frame. The first conveying device includes an anti-fall guard plate and a first conveyor belt. The second conveying device includes a first guard plate and a second guard plate disposed opposite to each other, and a second conveyor belt disposed between the first guard plate and the second guard plate. A positioning channel is provided between the first guard plate and the second guard plate. A plurality of positioning rods are spaced apart on the conveyor belt. Each positioning rod is perpendicular to the surface of the second conveyor belt and extends upward through the positioning channel to extend beyond the plane where the first guard plate and the second guard plate are located. A screening device for screening mosquito coil tablets is provided between the first conveyor device and the second conveyor device. A functional gantry frame is provided on the second support frame. The functional gantry frame is suspended above the second conveyor device. A moving bucket-feeding device for grabbing mosquito coil tablets into a bucket is provided on the functional gantry frame. The screening device includes two screening discs arranged opposite each other. Four screening grooves are arranged around the screening discs. The screening grooves are arc-shaped. In this patent, the moving bucket-loading device for grabbing mosquito coils into the bucket adopts a support frame and suction cup structure. The suction cup structure can pick up a single mosquito coil. However, if it is used to pick up multiple mosquito coils packaged in a moisture-proof film or packaging bag, since the moisture-proof film or packaging bag is usually larger than the mosquito coil in actual packaging and is in a relatively loose state, it is not easy to pick up the mosquito coil stably and accurately if the suction cup structure is used, resulting in irregular filling of the bucket or damage to the mosquito coil.

[0005] Based on the above issues, the applicant conducted research, which led to this case. Summary of the Invention

[0006] The purpose of this invention is to provide a clamping and filling mechanism that can pack drums more neatly and reduce the risk of product damage.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A mosquito coil clamp holding and loading mechanism includes an installation plate, multiple clamping blocks disposed below the installation plate, and a drive mechanism for driving the multiple clamping blocks to move synchronously toward or away from the center of the installation plate. The clamping blocks are disposed on the installation plate via a guide mechanism. The drive mechanism includes at least two drive wheels rotatably disposed on the installation plate, a drive belt sleeved on the drive wheels, and a power source capable of driving the drive wheels to rotate forward and backward. The clamping blocks are fixedly connected to the drive belt.

[0008] In a preferred embodiment of the present invention, the power source is an electric motor, and the inner surface of the clamping block is arc-shaped.

[0009] In a preferred embodiment of the present invention, there are 3 to 4 transmission wheels.

[0010] In a preferred embodiment of the present invention, there are four clamping blocks, which are evenly distributed around the mounting plate, and there are four transmission wheels, which are rotatably mounted on the mounting plate via a support shaft arranged in a vertical direction.

[0011] As a preferred embodiment of the present invention, it further includes four guide wheels disposed on the travel path of the transmission belt, the guide wheels pressing against the transmission belt, and the transmission belt being arranged in a cross shape above the mounting plate.

[0012] In a preferred embodiment of the present invention, the mounting plate is arranged in a horizontal direction, and a strip groove is formed on the mounting plate, extending from the upper end face to the lower end face of the mounting plate. The transmission belt is connected to the clamping block through a connecting block, and the connecting block is slidably arranged in the strip groove.

[0013] In a preferred embodiment of the present invention, the guiding mechanism includes a guide rail disposed at the lower end of the mounting plate and a guide groove disposed on the connecting block, wherein the guide rail and the guide groove are configured to cooperate with each other.

[0014] In a preferred embodiment of the present invention, a fixing plate is provided above the mounting plate, and the fixing plate is connected to the mounting plate by a connecting column. The power source is a motor mounted on the fixing plate, and the output shaft of the motor is connected to the transmission wheel.

[0015] As a preferred embodiment of the present invention, it further includes a lateral drive mechanism for moving the mounting plate left and right and a longitudinal drive mechanism for moving the mounting plate up and down.

[0016] As a preferred embodiment of the present invention, it further includes a pressing mechanism, which includes a pressing shaft disposed at the center of the mounting plate. The pressing shaft is movably disposed on the mounting plate. A pressing block is provided at the lower end of the pressing shaft. The pressing block is located below the mounting plate and between each of the clamping blocks. It also includes a pressing drive mechanism for driving the pressing shaft to move up and down.

[0017] The technical solution of this invention uses a power source to drive the transmission wheel to rotate forward and backward. The rotation of the transmission belt is converted into the clamping blocks synchronously moving towards the center of the mounting plate to achieve a clamping action or moving away from the center of the mounting plate to achieve a releasing action. In the mechanical field, the flexible nature of the transmission belt allows it to absorb some of the impact and vibration from the power source or load, enabling the clamping blocks to achieve flexible clamping when holding mosquito coils, reducing the risk of mosquito coil breakage (especially for mosquito coils that do not require disassembly; conventional mosquito coils consist of two nested coil blanks, which are separated before use. Mosquito coils that do not require disassembly are pre-packaged during manufacturing and can be used directly without separating the coil blanks. However, since mosquito coils that do not require disassembly are single coil blanks, the risk of breakage is greater, and the packaging requirements are higher). This invention cleverly combines the transmission belt and the clamping blocks for holding mosquito coils, achieving a clamping effect that is difficult to achieve with ordinary rigid grippers. Because the forward and reverse rotation speeds of the drive wheels are easily controlled, the drive belt can rotate smoothly, making the movement precision of the clamping blocks more controllable. Since each clamping block can move towards or away from the product, synchronously clamping it around the perimeter, the product can fall more neatly into the bucket after release, reducing the risk of product damage. During loading, if the bucket is slightly deformed, the clamping blocks can be used to open it, allowing the product to be loaded more smoothly. In a preferred embodiment of the invention, the power source is a motor, and there are four drive wheels that move synchronously using a synchronous belt. The clamping blocks have good synchronization, and their inner surfaces are arc-shaped, making them particularly suitable for clamping packaging bags containing multiple disc-shaped mosquito coils. They clamp the packaging bag evenly from all sides, and the motor allows for precise speed control and controllable torque, reducing the risk of mosquito coil damage. In a preferred embodiment of the invention, a pressing block and a pressing shaft are provided between each clamping block, making the device structure compact. The pressing block can press the packaging bag into the mosquito coil bucket, allowing the packaging bag to be arranged more neatly, thus facilitating the placement of multiple packaging bags in the mosquito coil bucket.

[0024] Reference Figures 1 to 5 The mosquito coil clamping and loading mechanism includes a mounting plate 10, multiple clamping blocks 40 disposed below the mounting plate 10, and a drive mechanism for driving the multiple clamping blocks 40 to move synchronously towards or away from the center of the mounting plate 10. The mounting plate 10 is horizontally positioned. In this embodiment, the mounting plate 10 is a disc. The multiple clamping blocks 40 are evenly arranged around the periphery of the mounting plate 10. When the multiple clamping blocks 40 approach each other, a clamping action is achieved. When the multiple clamping blocks 40 move away from the center of the mounting plate 10, a release action is achieved. The clamping blocks 40 are mounted on the mounting plate 10 through a guide mechanism, which allows the clamping blocks 40 to move more smoothly. At the same time, the guide mechanism can also provide some support for the clamping blocks 40. The drive mechanism includes at least two drive wheels 30 rotatably mounted on the mounting plate 10, a drive belt 20 sleeved on the drive wheels 30, and a power source that can drive the drive wheels 30 to rotate forward and backward. The clamping blocks 40 are fixedly connected to the drive belt 20. When the drive wheels 30 rotate, the drive belt 20 rotates (i.e., travels on the drive wheels).

[0025] In this invention, the power source can be a commonly used structure in the mechanical field capable of driving the transmission wheel 30 to rotate. For example, the transmission wheel 30 may have a gear section, which is driven by a linear drive mechanism (e.g., an electric push rod) to move the rack, thereby driving the gear section to rotate, thus driving the transmission wheel 30 to rotate. As a preferred embodiment of this invention, the power source is a motor 32, and the inner surface of the clamping block 40 is arc-shaped. The output shaft of the motor 32 can be directly connected to the transmission wheel 30, thereby driving the transmission wheel 30 to rotate. The output shaft of the motor 32 can also drive the transmission wheel 30 to rotate via intermediate transmission components such as gears or belts. In this application, the transmission belt is a flexible transmission belt in the mechanical field, and the material can be common materials such as rubber, polyurethane, polyvinyl chloride, or synthetic fibers.

[0026] In a preferred embodiment of the present invention, there are 2 to 4 transmission wheels 30.

[0027] In a preferred embodiment of the present invention, there are four clamping blocks 40 evenly distributed around the mounting plate 10, and four transmission wheels 30 rotatably mounted on the mounting plate 10 via a support shaft 31 arranged vertically. In an embodiment, the support shaft 31 is rotatably mounted on the mounting plate 10 via bearings, and the transmission wheels 30 are connected to the support shaft 31 via keys. Alternatively, the support shaft 31 can be fixedly connected, and the transmission wheels 30 can be connected in a manner that allows them to rotate relative to the support shaft 31.

[0028] In a preferred embodiment of the invention, four guide wheels 60 are further provided on the travel path of the transmission belt 20. The guide wheels 60 abut against the transmission belt 20, which is arranged in a cross shape above the mounting plate 10. Preferably, the guide wheels 60 are mounted on the mounting plate 10 via a vertical axle 61. Preferably, the guide wheels 60 are rotatably mounted on the axle 61. The guide wheels 60 are used to adjust the direction of the transmission belt 20, so that the clamping block 40 can move along a predetermined direction.

[0029] In a preferred embodiment of the present invention, the mounting plate 10 is provided with a strip groove 11, which extends from the upper end face to the lower end face of the mounting plate 10. The transmission belt 20 is connected to the clamping block 40 through a connecting block 41. The connecting block 41 is slidably disposed in the strip groove 11. Specifically, the upper end of the connecting block 41 passes through the strip groove 11 and is fixed on the transmission belt 20, and the lower end is connected to the clamping block 40.

[0030] In a preferred embodiment of the present invention, the guiding mechanism includes a guide rail 12 disposed at the lower end of the mounting plate 10 and a guide groove 42 disposed on the connecting block 41, wherein the guide rail 12 and the guide groove 42 are configured to cooperate. In the present invention, the clamping block 40 can be supported by means of the transmission belt 20, and preferably, the clamping block 40 is also supported and guided by means of the guide rail 12.

[0031] In a preferred embodiment of the present invention, a fixing plate 80 is provided above the mounting plate 10. The fixing plate 80 is arranged in a horizontal direction and is connected to the mounting plate 10 by a connecting column (in the embodiment, the wheel axle 61 is used as the connecting column). The power source is a motor 32 provided on the fixing plate 80. The output shaft of the motor 32 is connected to the transmission wheel 30, specifically by a belt and a pulley, and is connected to the support shaft 31.

[0032] The present invention also includes a transverse drive mechanism 70 for moving the mounting plate 10 left and right and a longitudinal drive mechanism 74 for moving the mounting plate 10 up and down. There are various ways to achieve the up-and-down and left-and-right movement of the mounting plate 10. For example, the transverse drive mechanism 70 can be mounted on another frame, and the longitudinal drive mechanism 74 can be mounted on the transverse drive mechanism, thereby realizing the left-and-right and up-and-down movement of the mounting plate 10 and related mechanisms. As a preferred embodiment of the present invention, it also includes a mounting plate 71, a horizontal plate 72 movably mounted on the mounting plate 71, and a transverse drive mechanism 70 for driving the horizontal plate 72 to move left and right along the mounting plate 71. The transverse drive mechanism 70 adopts a lead screw mechanism commonly used in the mechanical field. A fixed plate 73 is provided on the horizontal plate 72, and the fixed plate 80 is movably mounted on the fixed plate 73 via a longitudinal guide rail. A longitudinal drive mechanism 74 for driving the fixed plate 73 to move up and down is connected to the fixed plate 73. The longitudinal drive mechanism 74 adopts a lead screw mechanism commonly used in the mechanical field.

[0033] As a preferred embodiment of the present invention, it further includes a pressing mechanism, which includes a pressing shaft 51 disposed at the center of the mounting plate 10. The pressing shaft 51 is movably disposed on the mounting plate 10. A pressing block 52 is provided at the lower end of the pressing shaft 51. The pressing block 52 is located below the mounting plate 10 and between each of the clamping blocks 40. It also includes a pressing drive mechanism 50 for driving the pressing shaft 51 to move up and down. The pressing drive mechanism 50 can be, for example, a cylinder.

[0034] The clamping and packing mechanism of the present invention, in conjunction with other mechanisms, can be used in various ways. For example, the clamping block 40 can be moved above the mosquito coil packaging bag by the lateral drive mechanism 70 and the longitudinal drive mechanism 74 to clamp the packaging bag, and the mosquito coil bucket can be moved below the clamping block 40. The clamping block 40 can then be inserted into the mosquito coil bucket to release the packaging bag. Alternatively, the packaging bag can be lifted to the inside of the clamping block 40, clamped by the clamping block 40, and then the lifting mechanism can be removed. The mosquito coil bucket can then be moved to the outside below the clamping block 40 to release the packaging bag. In this case, the lateral drive mechanism 70 and the longitudinal drive mechanism 74 may not be necessary.

[0035] The scope of protection of this invention is not limited to this embodiment. Any similar modifications made to it are considered to be within the scope of protection of this invention.
