[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] Example 1

[0034] This embodiment provides a paper tube collecting device, the structure of which is as follows: Figures 1 to 6 As shown, it includes a frame 100, a height control component 200 and a drive component 300.

[0035] The frame 100 is provided with a finished product separation table 110 , and a collection unit 120 is provided on the frame 100 below the finished product separation table 110 . The collection unit 120 is provided with a collection guide 130 , and the collection guide 130 guides the paper tube from the finished product separation table 110 to the collection unit 120 .

[0036] The collection unit 120 is provided with an accommodating space, and the finished product separation table 110 includes two limiting tubes 111 arranged in parallel, with a drop-out opening 111a left in the middle of the limiting tubes 111, and the opening of the accommodating space is opposite to the drop-out opening 111a; the limiting tube 111 on one side is set on the frame 100 through a sliding track, so that the range of the drop-out opening 111a can be dynamically adjusted; the collection guide 130 enters the drop-out opening 111a to enlarge the drop-out opening 111a.

[0037] The height control assembly 200 is connected to the collection unit 120 and includes a multi-stage linkage lifting member 210 and a traction mechanism disposed between the lifting members 210. The collection guide 130 is connected to one of the lifting members 210. When the height control assembly 200 is raised, the collection guide 130 enters the drop opening 111a and contacts the limiting tube 111 connected to the sliding track, thereby increasing the range of the drop opening 111a and allowing the paper tube to smoothly enter the storage space. At this time, the opening of the storage space is also close to the drop opening 111a, making it difficult for the paper tube to slip out of the storage space. The height control assembly 200 can synchronously control the position of the collection guide 130, thereby synchronously controlling the size of the drop opening 111a.

[0038] The driving assembly 300 is connected to the height control assembly 200 to drive the multi-stage lifting members 210 to move synchronously to adjust the height of the accommodating space, thereby adjusting the size of the accommodating space.

[0039] The paper tube collection device provided in this embodiment includes a height control device with a multi-stage linkage lifting component 210, which increases the movement stroke of the collection unit 120 to facilitate dynamic adjustment of the size of the accommodating space of the collection unit 120 without increasing the size of the height control component 200 and the drive component 300, thereby achieving the effect of efficient space utilization and facilitating the collection of paper tubes and the subsequent outflow of paper tubes.

[0040] Example 2

[0041] like Figure 2 As shown, the collecting guide 130 in this embodiment is a guiding rod vertically arranged on the edge of the lifting member 210, and a guiding slope 131 is provided at the end of the rod, which can effectively guide the paper tube to fall into the accommodating space, and a wedge-shaped surface is also provided on the other side of the guiding slope 131. When the collecting guide 130 contacts the limiting tube 111, it can push the limiting tube 111 to deviate to one side, thereby expanding the width of the drop port 111a, so that the paper tube falls smoothly.

[0042] Designing the height control assembly 200 to be hollow and surrounding the space housing the collection unit 120 effectively utilizes space and increases the compactness of the device. The multi-stage lift 210 provides a greater height travel, occupies less space when retracted, and does not require the drive assembly 300 to have a large travel range. Instead, the drive assembly 300's travel can be amplified to achieve a wider range of height adjustment.

[0043] like Figure 3 As shown, the lifting member 210 is a hollow lifting sleeve 211 , and the sizes of the multiple-stage lifting sleeves 211 are gradually enlarged and connected in sequence, and the multiple-stage lifting sleeves 211 enclose the accommodating space of the collecting unit 120 .

[0044] like Figure 3 As shown, the multi-stage lifting member 210 in this embodiment includes a driving stage 211a connected to the driving assembly 300, a working stage 211c connected to the collecting guide 130, and a transition stage 211b located between the driving stage 211a and the working stage 211c. A traction mechanism is provided between each stage of the lifting members 210. When a lifting sleeve 211 is driven by the driving assembly 300, the traction mechanism triggers the other lifting members 210 to rise and fall together. This multiplies the single movement distance of the driving assembly 300 by several times, increasing the range of motion. Furthermore, when the lifting members 210 are retracted, they occupy less space.

[0045] like Figure 3 As shown, the height control assembly 200 further includes a lifting base 230 , which provides an installation space for the driving assembly 300 and serves as an installation base for the lifting member 210 .

[0046] In order to ensure that the multi-stage lifting member 210 maintains stability in the height direction during the lifting process, a guide structure is further provided between each stage of the lifting member 210 and between the driving stage 211a and the lifting base 230, which includes a guide groove 212 formed at the corner point of the lifting sleeve 211, and the guide groove 212 forms a negative angle inward. Adjacent guide grooves 212 are nested in sequence to form a number of linear motion pairs to achieve a guiding effect.

[0047] like Figure 3 and Figure 4 As shown, the traction mechanism in this embodiment includes a pulley block 221 provided on the lifting members 210, and a traction clamp 222 connecting the pulley block 221 to the adjacent lifting members 210. Each level of the lifting members 210 is provided with a pulley block 221 and a traction clamp 222. The lifting members 210 of the current level are driven by the traction mechanism of the lifting member 210 of the previous level, and the traction mechanism of the current level drives the lifting member 210 of the next level.

[0048] For example Figure 4 In the figure, the pulley group 221 on the driving stage 211a is connected to the lifting base 230 and the transition stage 211b, and the pulley group 221 on the transition stage 211b is connected to the driving stage 211a and the working stage 211c. When the driving stage 211a is driven to rise and fall by the driving assembly 300, the pulley group 221 on the driving stage 211a drives the transition stage 211b to move relative to the driving stage 211a, and the pulley group 221 on the transition stage 211b drives the working stage 211c to rise and fall.

[0049] like Figure 4 and Figure 5 As shown, the pulley assembly 221 includes two traction pulleys 221a and a traction rope 221b wound around the traction pulleys 221a. The two traction pulleys 221a are distributed vertically along the height direction of the lifting member 210. The pulley assembly 221 is fixed to the side wall of the lifting member 210, with the upper and lower traction pulleys 221a located on the same side of the lifting member 210. The traction rope 221b is divided into two parallel sections by the traction pulleys 221a. Adjacent lifting members 210 are respectively fixedly connected to one rope section via a traction clamp 222. In the retracted state, the position of the traction clamp 222 of the upper stage is staggered with the position of the traction clamp 222 of the lower stage.

[0050] Since the pulley assembly 221 is on the inner wall of the lifting member 210, in order to allow the traction clamp 222 of the outer level to be connected to the traction rope 221b, as shown in FIG. Figure 4 and Figure 5As shown, a clearance channel 213 suitable for the traction clamp 222 to pass through is opened on the side wall of the lifting member 210, and the clearance channel 213 is opposite to the position of the traction rope 221b. The traction clamp 222 on the adjacent lifting member 210 passes through the clearance channel 213 and is connected to the traction rope 221b on the lifting member 210 at the same level.

[0051] For example, when the driving stage 211a moves, one section of the traction rope 221b on the driving stage 211a is clamped by the traction clamp 222 on the lifting base 230, causing the traction pulley 221a to rise and fall along with the driving stage 211a. At this point, the traction rope 221b begins to rotate around the traction pulley 221a, while the traction clamp 222 on the other section connects to the transition stage 211b. This allows the transition stage 211b to move relative to the driving stage 211a in the same direction as the driving stage 211a. The working stage 211c is not equipped with a pulley block 221, but only with a traction clamp 222. To ensure force balance, a pulley block 221 and a traction clamp 222 are installed at both ends of the lifting member 210.

[0052] like Figure 6 As shown, the driving assembly 300 in this embodiment includes: a rotating seat 310, which is fixed on the lifting base 230 and has a servo motor on it; a driving screw 320, one end of which is rotatably set in the rotating seat 310 and connected to the servo motor, and its axial direction is parallel to the moving direction of the lifting member 210; a lifting nut 330, which is fixedly connected to the lifting member 210 located at the driving stage 211a.

[0053] The servo motor can use a programmable logic controller to control its rotation angle in order to achieve precise control of the moving height.
