Description

Technical Field

[0001] This utility model belongs to the technical field of straw packaging machines, and specifically relates to a feeding device for a straw packaging machine. Background Technology

[0002] Paper straws are a common type of tube used for drinking beverages. After production, they are fed into a packaging machine via a feeding device. While existing feeding devices can meet the basic requirements for feeding straws, the feeding structure is stationary, and the straws can only be fed by gravity. This easily leads to excess straw getting stuck in the feeding structure, affecting the efficiency of straw removal and thus the overall packaging efficiency and effect, ultimately failing to fully meet user needs.

[0003] For example, the utility model patent with authorization announcement number CN 219770363 U discloses an automatic straw packaging machine. The technical solution of this patent document includes: a feeding hopper with an open top and an open bottom; a packaging machine housing with two fixed seats fixedly installed on the top of the packaging machine housing, and the bottom of the feeding hopper movably abutting against the top of the packaging machine housing; and a disassembly assembly including two insert plates. A sleeve plate is fixedly fitted on the outside of the feeding hopper, and slots are opened on both the left and right sides of the sleeve plate. The two insert plates are movably engaged in the corresponding slots. Although this can achieve the detachable fixing of the feeding hopper and the packaging machine housing, the feeding hopper is in a static state during the feeding process. Therefore, the straws can only be fed by gravity. Moreover, the feeding hopper has a structure that is larger at the top and smaller at the bottom, which makes it easy for the straws to get stuck and blocked during the feeding process. Therefore, it cannot fully meet people's needs. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a feeding device for a straw packaging machine. This device not only meets the basic requirements for feeding straws but also prevents straws from getting stuck or blocked during the feeding process, thus better meeting people's usage needs.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a feeding device for a straw packaging machine, including a support frame for connecting to the top of the straw packaging machine body, a plurality of vibration springs vertically arranged on the top of the support frame, a mounting frame on the top of the vibration springs, a feeding hopper on the mounting frame, a feeding cylinder adapted to the feeding port of the packaging machine at the lower end of the feeding hopper, a feeding stop module connected to the feeding cylinder on the mounting frame, and a vibration motor on the mounting frame.

[0006] As a further improvement of this utility model, the support frame is also provided with a guide slot, and the mounting frame is also provided with a guide plate that is inserted into the guide slot.

[0007] As a further improvement of this utility model, the feed shut-off module includes a vertical plate mounted on a mounting frame, a telescopic push rod mounted on the vertical plate, a mounting plate mounted on the output shaft of the telescopic push rod, an inlet and outlet at the lower side of the feed cylinder, and a shut-off plate mounted on the mounting plate that plugs into the inlet and outlet and can shut off the feed cylinder. The telescopic push rod is a cylinder or an electric push rod.

[0008] As a further improvement of this utility model, a guide tube located at the side end of the telescopic push rod is also provided on the vertical plate, and a guide rod that is inserted into the guide tube is provided on the mounting plate.

[0009] As a further improvement of this utility model, the feed hopper and the mounting frame are snapped together. The feed cylinder is also equipped with a snap-fit ​​baffle that snaps onto the top of the mounting frame. The snap-fit ​​baffle is further equipped with mounting bolts that are screwed onto the mounting frame. The mounting frame is equipped with threaded mounting holes that are screwed onto the mounting bolts. The snap-fit ​​connection between the feed hopper and the mounting frame facilitates quick loading, unloading, and cleaning. The feed cylinder is screwed onto the mounting frame via the snap-fit ​​baffle and mounting bolts, balancing assembly efficiency and connection strength, and is suitable for production environments with frequent material changes or cleaning.

[0010] As a further improvement of this utility model, a fixing plate is also provided at the bottom side of the support frame. The fixing plate is provided with fixing bolts for screwing into the top of the straw packaging machine body. The top of the straw packaging machine body is provided with threaded fixing holes for screwing into the fixing bolts. Through the cooperation of the fixing plate, fixing bolts and threaded fixing holes, the support frame and the straw packaging machine body can be flexibly fixed.

[0011] As a further improvement of this utility model, a top cover is also snapped onto the top of the feeding hopper. A first magnetic fixing piece is provided on the top and bottom wall of the top cover, and a second magnetic fixing piece is provided on the top of the feeding hopper to be attracted and fixed to the first magnetic fixing piece. The removable top cover effectively prevents dust and foreign objects from entering the hopper, ensuring the cleanliness of the straw and preventing the straw from flying out from the top of the feeding hopper. The top cover is quickly snapped on by the first and second magnetic fixing pieces, allowing for opening and closing without tools, greatly improving the convenience of feeding and cleaning. As a further improvement of this utility model, a handle is also provided on the top cover, and an anti-slip sleeve is also provided on the handle. The handle with the anti-slip sleeve on the top cover makes it convenient for users to grip and operate, and can safely and effortlessly open the top cover, especially in wet, slippery environments or when working with gloves on, reflecting a humanized design.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: Firstly, the feed hopper is mounted on a frame supported by multiple vibrating springs, and the frame is equipped with a vibrating motor. During operation, the vibrating motor starts, causing the entire feed hopper and feed cylinder to vibrate at high frequency and micro-amplitude. This allows the suction tubes to slide down in an orderly manner under the combined action of gravity and vibration, avoiding blockages caused by the stacking, sticking, or misalignment of the suction tubes. The vibration is transmitted through the springs, ensuring effective vibration transmission and also acting as a buffer to prevent damage to the equipment body from severe vibrations, while improving operational stability.

[0013] Secondly, the installation plate is moved by a telescopic push rod, which in turn moves the stop plate into or out of the inlet and outlet of the feeding cylinder, thereby opening and closing the feeding. This structure is responsive and reliable, and can be linked with the packaging machine control system to achieve timed and quantitative feeding, avoiding waste or blockage caused by overfeeding.

[0014] Thirdly, a guide structure (guide tube and rod) is set on the side end of the telescopic push rod, which effectively limits the offset or shaking of the mounting plate during the movement, ensuring that the stop plate can be accurately aligned with the inlet and outlet, and improving the repeatability and service life of the stop action.

[0015] Fourth, the support frame is equipped with guide slots, and the mounting frame has corresponding guide plates. The two are interlocked to form a stable vertical guide structure. This design not only enhances the rigidity and resistance to eccentric loads of the overall structure, but also simplifies the installation process and facilitates equipment maintenance and disassembly.

Detailed Implementation

[0019] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0020] like Figure 1 , 2 As shown, a feeding device for a straw packaging machine includes a support frame 101 for connecting to the top of the straw packaging machine body. Multiple vibration springs 102 are vertically arranged on the top of the support frame 101. A mounting frame 103 is mounted on the top of each vibration spring 102. A feeding hopper 104 is mounted on the mounting frame 103. A feeding cylinder 105, adapted to the feeding inlet of the packaging machine, is located at the lower end of the feeding hopper 104. A feeding stop module connected to the feeding cylinder 105 is also mounted on the mounting frame 103. A vibration motor 106 is also mounted on the mounting frame 103. A controller electrically connected to the vibration motor 106 and the telescopic push rod 202 is also mounted on the support frame 101.

[0021] like Figure 1 , 3 As shown, the support frame 101 is also vertically provided with a guide slot 107, and the mounting frame 103 is also vertically provided with a guide plate 108 that is inserted into the guide slot 107. Through the vertical insertion and cooperation of the guide slot 107 and the guide plate 108, the mounting frame 103 and the feed hopper 104 can vibrate stably in the vertical direction, and the vibration spring 102 can be prevented from being easily bent and deformed and damaged.

[0022] like Figure 1 , 3As shown, the feed shut-off module includes a vertical plate 201 mounted on a mounting frame 103. A telescopic push rod 202 is horizontally mounted on the vertical plate 201. A mounting plate 203 is mounted on the output shaft of the telescopic push rod 202. An inlet / outlet 204 is provided at the lower side of the feed cylinder 105. A shut-off plate 205 is mounted on the mounting plate 203, which is inserted into the inlet / outlet 204 and can shut off the feed cylinder 105. The telescopic push rod 202 is a cylinder or an electric push rod.

[0023] like Figure 1 , 3 As shown, the vertical plate 201 is also provided with a guide tube 206 located at the side end of the telescopic push rod 202, and the mounting plate 203 is provided with a guide rod 207 that is inserted into the guide tube 206. The design of the guide tube 206 and the guide rod 207 ensures that the mounting plate 203 moves smoothly without deviation, and that the stop plate 205 can be accurately aligned with the inlet and outlet 204 to avoid jamming or wear.

[0024] like Figure 1 , 2 As shown, the feed hopper 104 is snapped into the mounting frame 103. The feed cylinder 105 is also equipped with a retaining plate 301 that snaps into the top of the mounting frame 103. The retaining plate 301 is also equipped with mounting bolts 302 that are screwed into the mounting frame 103. The mounting frame 103 has threaded mounting holes that are screwed into the mounting bolts 302. The snap-fit ​​connection between the feed hopper 104 and the mounting frame 103 facilitates quick loading, unloading, and cleaning. The feed cylinder 105 is screwed into the mounting frame 103 via the retaining plate 301 and mounting bolts 302, balancing assembly efficiency and connection strength, making it suitable for production environments with frequent material changes or cleaning.

[0025] Before feeding, the output shaft of the telescopic push rod 202 is driven to a certain length, so that the stop plate passes through the inlet and outlet 204 and enters the feed cylinder 105 and abuts against the inner wall of the feed cylinder 105, thereby putting the feed cylinder 105 in a "closed" state and preventing the suction tube from falling autonomously during the subsequent feeding process.

[0026] Afterwards, the operator can add an appropriate amount of straws into the feed hopper 104; then the vibration motor 106 on the mounting frame 103 can be started; the vibration motor 106 generates high-frequency micro-amplitude vibration, which is transmitted to the feed hopper 104 and the feed cylinder 105 through the mounting frame 103; the vibration is transmitted from the support frame 101 through the vibration spring 102, which plays a buffering and shock-absorbing role to avoid impact on the packaging machine body; under the combined action of vibration and gravity, the straws gradually arrange themselves neatly in the feed hopper 104 and move downwards, tending towards the outlet of the feed cylinder 105, in preparation for feeding.

[0027] After completing one packaging cycle, the controller drives the telescopic push rod 202 (cylinder or electric push rod) to move; the output shaft of the telescopic push rod 202 extends, driving the output shaft of the telescopic push rod 202 to shorten by a certain length, causing the mounting plate 203 to move horizontally along the direction of the guide tube 206 and the guide rod 207; the stop plate 205 on the mounting plate 203 exits from the inlet and outlet 204 of the feed cylinder 105, opening the channel; under the action of gravity and continuous vibration, the suction tube falls orderly into the feed inlet of the packaging machine, starting a new round of packaging operations.

[0028] When the preset feeding amount is reached or the packaging machine is paused, the control system sends a stop signal; the telescopic push rod 202 retracts, causing the mounting plate 203 to move in the opposite direction. The stop plate 205 is reinserted into the inlet and outlet 204 of the feed cylinder 105 to cut off the flow path of the suction tube and prevent the suction tube from continuing to fall and causing accumulation or blockage; at this time, the system enters standby mode and waits for the next feeding command.

[0029] The above-mentioned "start → feed → stop → wait" process is executed cyclically according to the packaging rhythm; it can be linked with PLC or main control system to realize fully automatic, quantitative and timed feeding; the vibration motor 106 can run intermittently or vibrate continuously at low frequency to maintain the straw in a loose state and prevent stacking jamming caused by long-term static placement.

[0030] According to another embodiment of the present invention, such as Figure 1 As shown, a fixing plate 303 is also provided at the bottom side of the support frame 101. The fixing plate 303 is provided with fixing bolts 304 for screwing into the top of the straw packaging machine body. The top of the straw packaging machine body is provided with threaded fixing holes for screwing into the fixing bolts 304. After the support frame 101 is placed on the top of the straw packaging machine body, the fixing bolts 304 can pass through the fixing plate 303 and screw into the threaded fixing holes, thereby achieving flexible fixing of the support frame 101 and the straw packaging machine body.

[0031] According to another embodiment of the present invention, such as Figure 2 , 4As shown, a top cover 305 is also snapped onto the top of the feeding hopper 104. A first magnetic fixing piece 306 is provided on the bottom wall of the top of the top cover 305, and a second magnetic fixing piece 307 is provided on the top of the feeding hopper 104 to be attracted and fixed to the first magnetic fixing piece 306. After a certain amount of straw is added to the feeding hopper 104, the top cover 305 can be snapped onto the top of the feeding hopper 104, and the straw is fixed by the attraction of the first and second magnetic pieces, so that the top cover 305 and the top of the feeding hopper 104 are flexibly and firmly fixed together, preventing the top cover 305 from falling off during the subsequent vibration and operation of the feeding hopper 104, and preventing the straw from flying out of the top of the feeding hopper 104; when the feeding hopper 104 is temporarily finished, the top cover 305 can also be flexibly fixed together with the feeding hopper 104, thereby effectively preventing dust and foreign objects from entering the hopper and ensuring the cleanliness of the straw.

[0032] According to another embodiment of the present invention, such as Figure 1 , 4 As shown, a handle 308 is also provided on the top cover 305, and an anti-slip sleeve 309 is provided on the handle 308. The handle 308 allows the top cover 305 to be moved easily, and the top cover 305 can be easily locked or released from the feed hopper 104. The anti-slip sleeve 309 allows the user to easily hold and operate the handle 308, especially in wet or slippery environments or when wearing gloves, so that the top cover 305 can be opened safely and effortlessly, reflecting a user-friendly design.

[0033] The above are preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
