Description

Technical Field

[0001] This utility model relates to the field of packaging technology, specifically a packaging machine. Background Technology

[0002] Asphalt modifiers are natural or synthetic organic or inorganic materials added to asphalt or asphalt mixtures. They can be melted or dispersed in asphalt to improve or enhance the road performance of asphalt. After production, asphalt modifiers usually need to be packaged using a packaging machine.

[0003] Existing baling machines typically use a powder conveying method to fill the packaging bags with asphalt modifier powder. Because it is a powder conveying method, and asphalt modifier powder has the characteristics of fine particles, the powder is in a flowing state during the conveying process. The mutual friction and collision between the particles can easily cause some powder to separate from the main fluid and form dust. The baling opening is generally an open or semi-open structure. When the powder enters the packaging bag, it will create a certain pressure fluctuation inside the packaging bag, causing some dust to overflow from the gaps or openings of the baling opening. Utility Model Content

[0004] The purpose of this utility model is to provide a baling machine to solve the problem mentioned in the background art. When baling asphalt modifier powder, the existing baling machine usually uses a powder conveying method to fill the packaging bag with powder. Because it is a powder conveying method, the asphalt modifier powder has the characteristics of fine particles. During the conveying process, the powder is in a flowing state. The mutual friction and collision between its particles can easily cause some powder to separate from the main fluid and form dust. The baling opening is generally an open or semi-open structure. When the powder enters the packaging bag, it will form a certain pressure fluctuation inside the packaging bag, causing some dust to overflow from the gaps or openings of the baling opening.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a baling machine, comprising a frame, a discharge section, and a clamping section:

[0006] The discharge section is located at the top of the frame and has a storage tank at the top of the frame. The storage tank has an inlet at the top and an outlet at the bottom. The clamping section is located at the bottom of the discharge section and has a support frame on the side of the discharge section. A rotating rod is rotatably mounted on the side of the support frame and a clamping block is mounted at the bottom of the rotating rod. A cylinder is mounted on the side of the storage tank and a lifting ring is mounted at the output end of the bottom of the cylinder. The lifting ring is slidably connected to the rotating rod. The lifting ring moves vertically to drive the rotating rod to rotate. The rotation of the rotating rod drives the clamping block to move and clamp the opening of the packaging bag.

[0007] By adopting the above technical solution, the cylinder can drive the lifting ring to move vertically, thereby causing the rotating rod to rotate around the support frame. This allows the clamping block to move accurately to the opening of the packaging bag and hold it in place, ensuring that the opening of the packaging bag is fixed and stable during the material discharge process, preventing material leakage, and improving the efficiency and quality of packaging.

[0008] Preferably, the discharge section also has a discharge screw rotatably disposed inside the storage tank, the discharge screw extending into the discharge port, and a motor disposed on the top of the storage tank, the output end of the motor being connected to the top of the discharge screw.

[0009] By adopting the above technical solution, the motor can drive the discharge screw to rotate inside the storage tank, and the material in the storage tank can be squeezed out from the discharge port evenly and stably by utilizing the spiral propulsion action of the discharge screw.

[0010] Preferably, the clamping part has a rotating shaft disposed on the side of the rotating rod, the rotating shaft being embedded in the rotating rod and rotatably connected to the rotating rod.

[0011] By adopting the above technical solution, the rotating rod can rotate smoothly around the axis of rotation.

[0012] Preferably, there are four support frames, which are arranged in a central rotational symmetry structure around the center of the discharge port, and each of the four support frames is rotatably connected to a rotating rod.

[0013] By adopting the above technical solution, the rotating rod can maintain balance and stability during rotation, supported by four centrally symmetrical support frames. The four support frames allow the clamping blocks to grip the bag opening from four different directions, ensuring a more secure and uniform grip.

[0014] Preferably, the clamping part also has a clamping block disposed at the bottom of the rotating rod, and the inner side of the clamping block is engraved with anti-slip texture.

[0015] By adopting the above technical solution, when the clamping block holds the bag opening, the anti-slip texture on the inside of the clamping block can increase the friction between the clamping block and the bag opening, preventing the bag from slipping out of the clamping block during the discharge process, and further improving the stability and reliability of the bag opening clamping.

[0016] Preferably, the clamping part also has a groove formed on the side of the rotating rod, and a sliding shaft is provided inside the lifting ring. The sliding shaft is embedded in the groove and slidably connected to the rotating rod.

[0017] By adopting the above technical solution, when the lifting ring moves vertically under the drive of the cylinder, the sliding shaft can slide smoothly in the sliding groove on the side of the rotating rod. This sliding connection method can convert the vertical movement of the lifting ring into the rotational movement of the rotating rod.

[0018] Preferably, the clamping part also has a groove provided on the side of the clamping block, in which a rubber ring is embedded, and the rubber ring abuts against the opening of the packaging bag.

[0019] By adopting the above technical solution, the elasticity of the rubber ring can be utilized to better fit the shape of the bag opening when the clamping block holds the bag opening, further enhancing the sealing effect of the bag opening and preventing material from leaking from the gap between the bag opening and the clamping block during the discharge process.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: by providing a clamping part, the lifting ring can be driven by a cylinder to move vertically, thereby causing the rotating rod to rotate around the support frame, so that the clamping block can be accurately moved to the position of the packaging bag opening and clamped, ensuring that the packaging bag opening is fixed and stable during the material discharge process, preventing material leakage, and improving packaging efficiency and quality; the rubber ring embedded in the groove on the side of the clamping block uses its own elasticity to better fit the packaging bag opening, enhancing the sealing effect and preventing material leakage.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] Please see Figure 1 , Figure 2 and Figure 3 This embodiment provides a technical solution: a packaging machine, including a frame 1, a discharge section 2, and a clamping section 3.

[0031] The discharge section 2 is located on the top of the frame 1. The discharge section 2 has a storage tank 201 located on the top of the frame 1. The top of the storage tank 201 has an inlet 202 and the bottom of the storage tank 201 has an outlet 203. A discharge screw 204 is rotatably installed inside the storage tank 201 and extends into the outlet 203. A motor 205 is installed on the top of the storage tank 201. The output end of the motor 205 is connected to the top of the discharge screw 204. The motor 205 can drive the discharge screw 204 to rotate inside the storage tank 201. By utilizing the spiral propulsion of the discharge screw 204, the material in the storage tank 201 is uniformly and stably extruded from the outlet 203.

[0032] The clamping part 3 is located at the bottom of the discharge part 2. The clamping part 3 has a support frame 301 located on the side of the discharge part 2. A rotating rod 302 is rotatably mounted on the side of the support frame 301, and a clamping block 305 is located at the bottom of the rotating rod 302. A cylinder 310 is located on the side of the storage tank 201. The cylinder 310 is a device that converts the energy of compressed air into mechanical energy. The working principle of the cylinder 310 is based on the mechanical movement achieved by the propulsion of compressed air. The above is existing technology and will not be elaborated further below. When selecting a model, its power should be selected to suit the needs of the device to ensure that it can drive the device. The object is driven, and a lifting ring 307 is provided at the output end of the cylinder 310. The lifting ring 307 is slidably connected to the rotating rod 302. The lifting ring 307 moves vertically to drive the rotating rod 302 to rotate. The rotation of the rotating rod 302 drives the clamping block 305 to move and clamp the opening of the packaging bag. The cylinder 310 can be used to drive the lifting ring 307 to move vertically, thereby causing the rotating rod 302 to rotate around the support frame 301, so that the clamping block 305 can accurately move to the position of the packaging bag opening and clamp it, ensuring that the packaging bag opening is fixed and stable during the discharge process, preventing material leakage, and improving the efficiency and quality of packaging.

[0033] Example 2

[0034] Please see Figure 4 , Figure 5 and Figure 6 This embodiment provides a technical solution: a packaging machine, including a clamping part 3, a rotating rod 302, and a lifting ring 307.

[0035] A rotating shaft 303 is integrally provided on the side of the rotating rod 302. The rotating shaft 303 is embedded in the rotating rod 302 and rotatably connected to the rotating rod 302, so that the rotating rod 302 can rotate smoothly around the rotating shaft 303.

[0036] Four support frames 301 are provided, arranged in a centrally rotationally symmetrical structure around the center of the discharge port 203. Each of the four support frames 301 is rotatably connected to a rotating rod 302, ensuring that the rotating rod 302 remains balanced and stable during rotation under the support of the four centrally rotationally symmetrical support frames 301. The four-directional support frames 301 enable the clamping block 305 to clamp the bag opening from four different directions under the drive of the rotating rod 302, ensuring a more secure and uniform clamping of the bag opening.

[0037] A clamping block 305 is integrally set at the bottom of the rotating rod 302. The inner side of the clamping block 305 is chiseled with anti-slip texture. When the clamping block 305 clamps the mouth of the packaging bag, the anti-slip texture on the inner side of the clamping block 305 increases the friction between the clamping block 305 and the mouth of the packaging bag, preventing the packaging bag from slipping out of the clamping block 305 during the discharge process, and further improving the stability and reliability of clamping the mouth of the packaging bag.

[0038] A groove 304 is provided on the side of the rotating rod 302, and a sliding shaft 308 is provided inside the lifting ring 307. The sliding shaft 308 is embedded in the groove 304 and slidably connected to the rotating rod 302. When the lifting ring 307 moves vertically under the drive of the cylinder 310, the sliding shaft 308 can slide smoothly in the groove 304 on the side of the rotating rod 302. This sliding connection method can convert the vertical movement of the lifting ring 307 into the rotational movement of the rotating rod 302.

[0039] A groove 306 is provided on the side of the clamping block 305, and a rubber ring 309 is embedded in the groove 306. The rubber ring 309 abuts against the opening of the packing bag. By utilizing the elasticity of the rubber ring 309, when the clamping block 305 clamps the opening of the packing bag, the rubber ring 309 can better fit the shape of the opening of the packing bag, further enhancing the sealing effect of the opening of the packing bag and preventing the material from leaking from the gap between the opening of the packing bag and the clamping block 305 during the discharge process.

[0040] Working principle: First, power on the device. Then, pour the material to be packaged into the storage tank 201 through the inlet 202 at the top of the storage tank 201. Next, place the packaging bag below the outlet 203. Start the cylinder 310. The output end of the cylinder 310 pushes the lifting ring 307 to move vertically downward. Since the sliding shaft 308 inside the lifting ring 307 is embedded in the sliding groove 304 on the side of the rotating rod 302 and is slidably connected to it, the vertical downward movement of the lifting ring 307 is controlled by the sliding shaft 308. The sliding motion within the chute 304 is converted into the rotational motion of the rotating rod 302. The rotating rod 302 rotates around the support frame 301 with the pivot 303 as the center, causing the bottom clamping blocks 305 to open. This allows the packaging bag to cover the discharge port 203. Then, the cylinder 310 is activated, causing the lifting ring 307 to rise, allowing the four clamping blocks 305 to move accurately from four different directions to the opening of the packaging bag and clamp it. The anti-slip texture on the inner side of the clamping blocks 305 increases the friction with the opening of the packaging bag, preventing spillage. The bag slips off; simultaneously, the rubber ring 309 embedded in the groove 306 on the side of the clamping block 305 uses its own elasticity to better fit the bag opening, enhancing the sealing effect and preventing material leakage. After the bag opening is stably clamped, the motor 205 on the top of the storage tank 201 is started. The output end of the motor 205 drives the discharge screw 204 to rotate inside the storage tank 201. The spiral propulsion of the discharge screw 204 evenly and stably squeezes the material in the storage tank 201 out of the discharge port 203, filling the bag. Inside the bag, when the material in the bag reaches the required amount, the motor 205 stops, the discharge screw 204 stops rotating, and the material stops being discharged. Then, the control cylinder 310 moves the lifting ring 307 vertically upward. Through the reverse sliding of the sliding shaft 308 in the sliding groove 304, the rotating rod 302 rotates in the opposite direction, and the clamping block 305 releases the bag opening. Finally, the bag filled with material is removed from below the discharge port 203, completing one packaging operation. By repeating this cycle, continuous material packaging work can be achieved.
