[0021] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0022] Understandably, referring to Figures 1 to 4The present invention relates to an automatic candy jar capping device, comprising a frame 100, a material rack 200, a clamping mechanism 300, and a capping mechanism 400. The frame 100 is equipped with a conveyor belt 110 for conveying the can body. The material rack 200 is inclinedly arranged on the frame 100 and is used to hold the cap. An outlet 210 is provided at the lower end of the material rack 200, through which the cap can be output. The clamping mechanism 300 includes two sets of conveyor belts 310. Two sets of conveyor belts 310 are respectively arranged on both sides of the conveyor belt 110. The conveyor belts 310 and the conveyor belt 110 move synchronously. The two sets of conveyor belts 310 are used to clamp and transport the can so that the can can abut against the cover. The capping mechanism 400 includes a connecting frame 410 and a roller 420. The connecting frame 410 is connected to the material rack 200. The roller 420 is rotatably connected to the connecting frame 410. The roller 420 can abut against the cover so that the cover can be closed on the can.

[0023] This device automates the capping process through the coordinated operation of the conveyor belt 110, the clamping mechanism 300, and the capping mechanism 400. The can is placed on the conveyor belt 110, which drives the can towards the clamping mechanism 300. Two sets of conveyor belts 310 clamp and transport the can, preventing positional shift and improving transport stability. Simultaneously, the material rack 200 is inclinedly arranged on the frame 100, housing the cap. The lower end of the material rack 200 has an outlet 210. The conveyor belt 310 drives the can to contact the cap, causing the cap to exit from the outlet 210 and rest on top of the can. The connecting frame 410 is connected to the material rack 200, and the roller 420 is rotatably connected to the connecting frame 410. When the conveyor belt 310 conveys the can, the roller 420 can abut against the cover to apply a smooth and continuous pressure to the cover, thereby enabling the cover to gradually fasten onto the can. The whole process does not require manual intervention, realizing the automatic fastening of the can and the cover, effectively improving production efficiency.

[0024] The material rack 200 has multiple lids stacked vertically, and at least a portion of the lids at the bottom protrudes into the outlet 210. When the two sets of conveyor belts 310 drive the tank to pass under the material rack 200, the upper end of the tank can hook the lid to realize the feeding of the lid one by one. Then, the roller 420 abuts against the lid and presses the lid into the tank, so that the lid can automatically close on the tank, improving production efficiency.

[0025] In addition, the distance between the two sets of conveyor belts 310 is less than or equal to the width of the tank, so that the two sets of conveyor belts 310 can stably clamp the tank, thereby preventing the tank from shifting position during transportation and improving the stability of the lid.

[0026] It should be noted that the conveyor belt 110 and the conveyor belt 310 move synchronously, enabling the tank to be smoothly transferred from the conveyor belt 110 to the conveyor belt 310, ensuring stable tank transport and reducing the possibility of positional deviation. The conveyor belt 110 and the conveyor belt 310 can be driven by a common drive shaft or an electronic control system.

[0027] Understandably, referring to Figure 1 , Figure 2 and Figure 4 The connecting frame 410 is rotatably connected to the material rack 200, and an elastic element 430 is connected between the connecting frame 410 and the material rack 200. The elastic element 430 is used to drive the connecting frame 410 to rotate, so that the roller 420 can move closer to the conveyor belt 110. The connecting frame 410 is rotatably connected to the material rack 200, one end of the elastic element 430 is connected to the connecting frame 410, and the other end is connected to the material rack 200, so that the elastic element 430 can pull the connecting frame 410 to rotate, so that the roller 420 can move closer to the conveyor belt 110. This not only adapts to the height deviation of the tank, but also maintains a stable pressing force, so that the roller 420 can fit tightly against the cover. Moreover, the elastic element 430 can buffer the impact between the roller 420 and the cover, improve the stability of the pressure applied by the roller 420 to the cover, and make the cover fit smoothly and accurately on the tank.

[0028] It should be noted that the elastic element 430 can be a spring, a sheet, or an elastic element such as a rubber or silicone part, and is not limited here.

[0029] Understandably, referring to Figure 1 and Figure 2 The frame 100 is fixedly connected to a first screw 221, which is threadedly connected to two nuts 222. The material rack 200 is arranged between the two nuts 222. The first screw 221 is fixed vertically to the frame 100, and both nuts 222 are threadedly connected to the first screw 221. By arranging the material rack 200 between the two nuts 222, the position of the material rack 200 on the frame 100 can be flexibly adjusted by rotating the two nuts 222. This allows for flexible output position of the cover, accommodating not only cans of different sizes but also ensuring accurate contact and sealing between the cover and the can, thus improving the adaptability of the device to products of different specifications.

[0030] The first screw 221 is provided in multiple ways, and each first screw 221 is provided with two nuts 222. The multiple first screws 221 are arranged on both sides of the material rack 200, which can enhance the support stability of the material rack 200 and improve its reliability.

[0031] Understandably, referring to Figure 1 and Figure 3The frame 100 is equipped with two limiting rods 120, which are respectively arranged on both sides of the conveyor belt 110 to limit the tank. The two limiting rods 120 are respectively arranged on both sides of the conveyor belt 110, and the tank is arranged between the two limiting rods 120. When the tank is conveyed on the conveyor belt 110, the two limiting rods 120 can guide and constrain the conveying direction of the tank, preventing the tank from deviating from the conveyor belt 110, so that the tank can be conveyed accurately and the feeding stability of the tank can be improved.

[0032] Specifically, refer to Figure 1 and Figure 3 The distance between the two limiting rods 120 gradually decreases along the conveying direction of the conveyor belt 110. By setting the distance between the two limiting rods 120 to gradually decrease along the conveying direction of the conveyor belt 110, the can can be precisely guided and its position corrected step by step, so that the can can move accurately to the center position of the two conveyor belts 310, so that the conveyor belts 310 can clamp the can, thereby improving the feeding stability of the can, preventing the can from getting stuck at the end of the conveyor belt 310, and improving the stability of the capping.

[0033] Specifically, refer to Figure 1 and Figure 3 An adjusting block 130 is fixedly connected to the frame 100, and an adjusting rod 121 is fixedly connected to the limiting rod 120. The adjusting rod 121 is slidably connected to the adjusting block 130 to adjust the distance between the two limiting rods 120. A second screw 131 is threadedly connected to the adjusting block 130, and the end of the second screw 131 can abut against the adjusting rod 121. The adjusting block 130 is fixedly connected to the frame 100, and the adjusting rod 121 is fixedly connected to the limiting rod 120. By setting the adjusting rod 121 to pass through the adjusting block 130, the limiting rod 120 can move closer to or further away from the adjusting block 130, which facilitates the adjustment of the distance between the two limiting rods 120. Then, the second screw 131 is screwed into the adjusting block 130 so that the end of the second screw 131 can abut against the adjusting rod 121, thereby locking the position of the limiting rod 120 to accommodate tanks of different sizes and specifications, improving versatility.

[0034] Understandably, referring to Figure 1 and Figure 3The clamping mechanism 300 also includes two sets of lifting components 320 and two sets of translation components 330. Each conveyor belt 310 is sequentially connected to the translation component 330 and the lifting component 320. The lifting component 320 drives the conveyor belt 310 to move vertically, and the translation component 330 drives the conveyor belt 310 to move horizontally. The lifting component 320, the translation component 330, and the conveyor belt 310 are connected in sequence. Through the cooperation of the lifting component 320 and the translation component 330, the conveyor belt 310 can move flexibly in both the horizontal and vertical directions, allowing the position of the conveyor belt 310 to be flexibly adjusted to adapt to different cans, improving the accuracy and success rate of capping, and enhancing the versatility of the automatic can capping device.

[0035] The lifting assembly 320 and the translation assembly 330 can both be linear cylinders, electric actuators, linear slide modules, etc., which will not be described in detail here.

[0036] Specifically, refer to Figure 1 and Figure 3 The lifting assembly 320 includes a fixed block 321, a first guide rod 322, a first lead screw 323, and a first movable block 324. The fixed block 321 is fixedly connected to the frame 100. The first guide rod 322 is fixed vertically on the fixed block 321. The first lead screw 323 is rotatably connected to the fixed block 321. The first movable block 324 is slidably connected to the first guide rod 322, and the first movable block 324 is threadedly connected to the first lead screw 323. The translation assembly 330 is connected to the first movable block 324. The fixed block 321 is fixedly connected to the frame 100. The first guide rod 322 is fixedly connected to the fixed block 321 in the vertical direction. The first movable block 324 is slidably connected to the first guide rod 322 so that the first movable block 324 can move along the axial direction of the first guide rod 322. By rotating the first lead screw 323, the first lead screw 323 can drive the first movable block 324 to slide on the first guide rod 322, thereby facilitating the adjustment of the position of the translation component 330 and enabling the conveyor belt 310 to move and adjust in the vertical direction, thus improving the convenience of adjustment.

[0037] Specifically, refer to Figure 1 and Figure 3The translation component 330 includes a second guide rod 331, a second lead screw 332, and a second movable block 333. The second guide rod 331 is fixedly connected to the first movable block 324 in the horizontal direction. The second lead screw 332 is rotatably connected to the first movable block 324. The second movable block 333 is slidably connected to the second guide rod 331, and the second movable block 333 and the second lead screw 332 are threadedly connected. The conveyor belt 310 is connected to the second movable block 333. The second guide rod 331 is fixedly connected to the first movable block 324 in the horizontal direction, and the second lead screw 332 is rotatably connected to the first movable block 324. By setting the second movable block 333 to be slidably connected to the second guide rod 331, when the second lead screw 332 is driven to rotate, the second movable block 333 can move axially along the second guide rod 331, thereby facilitating the adjustment of the horizontal position of the conveyor belt 310 and improving the positional flexibility of the conveyor belt 310.

[0038] Understandably, referring to Figure 2 and Figure 4 The material rack 200 includes a base plate 223 and multiple support elements 224. The base plate 223 is inclinedly connected to the frame 100, and the outlet 210 is arranged on the base plate 223. The multiple support elements 224 are arranged in parallel and spaced on the base plate 223 to form a space for accommodating the cover. The multiple support elements 224 are arranged in parallel and spaced on the base plate 223, which is inclined so that the cover can automatically slide towards the outlet 210 under gravity, realizing automatic output of the cover. In addition, the multiple support elements 224 are arranged at intervals, and the remaining amount of the cover can be observed through the gap between two adjacent support elements 224, thereby facilitating the replenishment of the cover and improving the convenience of use.

[0039] Among them, the support element 224 can be a support rod, support plate, etc., which will not be described in detail here.
