[0038] like Figure 1 As shown, an embodiment of the present invention provides a paper-crushing device that can crush a stack of cardboard boxes one sheet at a time.

[0039] The paper feeding device includes a paper feeding mechanism, which includes a paper feeding assembly 100 and a drive assembly 200, with the drive assembly 200 being drivenly connected to the paper feeding assembly 100.

[0040] Combination Figure 2 and Figure 3The paper feed assembly 100 includes a mounting frame 110, two drive wheels 120, a paper feed belt 130, and a tensioning unit 140.

[0041] Mounting bracket 110 serves as the mounting base, which can be fixed in other locations or provide mounting positions for other components.

[0042] Two drive wheels 120 are spaced apart on the mounting frame 110 along a preset direction.

[0043] Specifically, the preset direction is horizontal, and the two transmission wheels 120 are arranged side by side and spaced apart along the preset direction, with the axes of the two transmission wheels 120 being parallel to each other. Each transmission wheel 120 is rotatable relative to the mounting bracket 110, and each transmission wheel 120 can rotate around its own axis.

[0044] The mounting bracket 110 includes a mounting block 111 and mounting side plates 112 arranged side by side on both sides of the mounting block 111 at intervals. Two drive wheels 120 are arranged between the two mounting side plates 112 and are spaced apart along a preset direction.

[0045] Furthermore, the mounting bracket 110 also includes a mounting shaft 113 connected between two mounting side plates 112. The two mounting shafts 113 are arranged side by side and spaced apart along a preset direction, and two transmission wheels 120 are rotatably sleeved on the two mounting shafts 113 respectively.

[0046] It should be noted that one of the transmission wheels 120 is defined as the driving wheel 121, and the other transmission wheel 120 is defined as the driven wheel 122. One of the mounting shafts 113 is defined as the first mounting shaft 1131, and the other mounting shaft 113 is defined as the second mounting shaft 1132. The driving wheel 121 is rotatably mounted on the first mounting shaft 1131, and the driven wheel 122 is rotatably mounted on the second mounting shaft 1132.

[0047] Furthermore, bearings are provided between the driving wheel 121 and the first mounting shaft 1131, and between the driven wheel 122 and the second mounting shaft 1132.

[0048] The paper feed belt 130 is set outside the two drive wheels 120.

[0049] Specifically, the two ends of the paper feed belt 130 are respectively sleeved on the two drive wheels 120. The paper feed belt 130 and the two drive wheels 120 mesh with each other. When the drive wheel 121 rotates, the paper feed belt 130 can run. When the paper feed belt 130 runs, it drives the driven wheel 122 to rotate.

[0050] The drive assembly 200 is connected to the drive wheel 121 and is used to drive the drive wheel 121 to rotate, thereby making the paper feed belt 130 run.

[0051] Furthermore, the outer side of the paper feed belt 130 can be coated with glue to increase the friction between it and the cardboard box, making it easier to feed the paper.

[0052] The tensioning unit 140 includes a bracket 141 rotatably connected to the mounting frame 110 and a tensioning wheel 142 connected to the bracket 141. The tensioning wheel 142 abuts against the inner wall of the paper feed belt 130. The bracket 141 is configured to rotate so that the position of the tensioning wheel 142 can be adjusted to change the tension of the paper feed belt 130.

[0053] Understandably, the tensioning wheel 142 abuts against the inner wall of the paper feed belt 130, thus keeping the paper feed belt 130 taut and improving transport efficiency. Of course, by rotating the bracket 141, the position of the tensioning wheel 142 can be adjusted, thereby changing the tension of the paper feed belt 130. Furthermore, the position of the tensioning wheel 142 can be adjusted to accommodate paper feed belts 130 of different lengths, ensuring that the tension of the paper feed belt 130 is within a suitable range.

[0054] In some embodiments, the paper feed assembly 100 further includes a support 150 connected to the mounting bracket 110 and located within the space formed around the paper feed belt 130, and a retainer 160 disposed on the support 150, the retainer 160 abutting against the bracket 141 so that the tension wheel 142 abuts against the inner wall of the paper feed belt 130.

[0055] Specifically, the paper feed belt 130 is a closed structure with its ends connected. A support member 150 is installed within the internal space formed by the belt. The support member 150 is also connected to two mounting side plates 112 to enhance the strength of the mounting frame 110. A retaining member 160 is disposed on the support member 150 and serves to abut against the bracket 141, allowing the bracket 141 to apply force to the tension wheel 142. This causes the tension wheel 142 to abut against the inner wall of the paper feed belt 130, thus keeping the paper feed belt 130 taut.

[0056] Specifically, one end of the bracket 141 is rotatably connected to the mounting bracket 110, and the other end is connected to the tensioning wheel 142.

[0057] In one embodiment, the abutment 160 is threadedly connected to the support 150, and the abutment 160 can be operatively driven to rotate the bracket 141 to change the tension between the tension wheel 142 and the paper feed belt 130.

[0058] It is understandable that the abutment 160 can be made of screws and threadedly connected to the support 150. By rotating the abutment 160, the position of the abutment 160 can be changed. Since the abutment 160 abuts against the bracket 141, the change in the position of the abutment 160 will adjust the angle of the bracket 141, thereby changing the tightness between the tension wheel 142 and the paper feed belt 130.

[0059] Specifically, one end of the bracket 141 is rotatably connected to the second mounting shaft 1132, and the other end of the bracket 141 is connected to the tension wheel 142, which is used to abut against the inner wall of the lower side of the paper feed belt 130; the abutment 160 is threadedly connected to the support 150, and rotating the abutment 160 can make the abutment 160 rise and fall. After the abutment 160 rises, the force between the tension wheel 142 and the paper feed belt 130 decreases, and after the abutment 160 falls, the force between the tension wheel 142 and the paper feed belt 130 increases.

[0060] It should be noted that after the position of the tension wheel 142 is adjusted, other screws can be used to lock the end of the bracket 141 away from the tension wheel 142 to the second mounting shaft 1132, further improving the stability of the bracket 141.

[0061] In other embodiments, the abutment 160 is a telescopic member, such as an electric push rod, which can drive the bracket 141 to rotate to change the tension between the tension wheel 142 and the paper feed belt 130.

[0062] Furthermore, the tensioning wheel 142 is rotatably connected to the bracket 141, and the tensioning wheel 142 rolls in cooperation with the inner wall of the paper feed belt 130.

[0063] It is understandable that the tensioning wheel 142 can rotate relative to the support 141. When the paper feed belt 130 is running, the paper feed belt 130 drives the tensioning wheel 142 to roll, which helps to reduce the friction between the tensioning wheel 142 and the paper feed belt 130 and reduce wear.

[0064] like Figure 3 As shown, in some embodiments, the paper feeding assembly 100 further includes a pad 170 connected to the mounting frame 110. The pad 170 can be connected to the mounting side plate 112 or disposed on the support member 150. The paper feeding belt 130 has a conveying section 131, which is the upper part of the paper feeding belt 130 and can convey the carton skin. The pad 170 is supported on the conveying section 131 to make the conveying end of the conveying section 131 flat.

[0065] Combination Figure 1 and Figure 3It is understood that the paper feeding device also includes a paper-stopping assembly 400 with a paper-stopping member 410. The paper-stopping member 410 is disposed opposite to the end of the conveying section 131, and the distance between the paper-stopping member 410 and the conveying section 131 is greater than the thickness of one cardboard box and less than the thickness of two cardboard boxes. When a stack of cardboard boxes is transported by the paper feeding belt 130, the bottommost cardboard box can pass through the gap between the paper-stopping member 410 and the conveying section 131. Thus, under the action of the paper feeding assembly 100, the cardboard boxes can be fed out one by one. By using the pad 170, the conveying end of the conveying section 131 is made flatter, which is beneficial for paper feeding.

[0066] Combination Figure 3 and Figure 4 In some embodiments, the paper feed assembly 100 further includes a first gear 180 coaxially arranged and connected to the drive wheel 121; the drive assembly 200 includes a rotary drive 210, a drive shaft 220 drivenly connected to the rotary drive 210, and a second gear 230 sleeved on the drive shaft 220, the second gear 230 meshing with the first gear 180.

[0067] It is understood that the rotary drive 210 is used to drive the transmission shaft 220 to rotate around the axis of the transmission shaft 220, thereby driving the second gear 230 to rotate. The second gear 230 can drive the first gear 180 to rotate, thereby driving the drive wheel 121 to rotate, thus realizing the operation of the paper feed belt 130.

[0068] Specifically, the first gear 180 is coaxially arranged and fixedly connected with the drive wheel 121, the second gear 230 is sleeved on the transmission shaft 220 and can rotate with the transmission shaft 220, and the rotary drive component 210 is a motor used to drive the transmission shaft 220 to rotate.

[0069] like Figure 4 As shown, in some embodiments, the drive assembly 200 further includes a support bearing assembly 240 sleeved on the middle of the drive shaft 220.

[0070] Understandably, the support bearing assembly 240 is used to support the middle part of the drive shaft 220, thereby reducing the degree of bending of the drive shaft 220.

[0071] Specifically, the support bearing assembly 240 includes a support bearing 241 sleeved in the middle of the drive shaft 220, and a support 242 that supports the support bearing 241.

[0072] Combination Figure 1 and Figure 5 In some embodiments, the paper feeding device further includes a support rod assembly 300 disposed on the mounting frame 110, the support rod assembly 300 being located above the paper feeding belt 130 and close to the conveying head end of the paper feeding belt 130.

[0073] Understandably, the support rod assembly 300 can support the carton skin. On the one hand, it can reduce the risk of the carton skin collapsing due to its softness. On the other hand, it can also make the front end of the carton skin tilt downwards, making it easier for the carton skin to be twisted out through the gap between the paper stop 410 and the conveying part 131.

[0074] Specifically, the support rod assembly 300 includes a clamping block 320 disposed on the mounting bracket 110 and a support rod 310 disposed on the clamping block 320. A connecting screw 330 is disposed below the clamping block 320 and is threadedly connected to the mounting bracket 110.

[0075] This utility model also provides a carton wrapping machine, including the paper feeding device described in the above embodiment.

[0076] The carton wrapping machine of this utility model includes the paper-feeding device described in the above embodiment. In the paper-feeding device, the drive assembly 200 is driven to rotate the drive wheel 121, thereby causing the paper-feeding belt 130 to run. The tension wheel 142 abuts against the inner wall of the paper-feeding belt 130, thereby keeping the paper-feeding belt 130 in a taut state and improving the transport efficiency. Of course, by rotating the bracket 141, the position of the tension wheel 142 can be adjusted, thereby changing the tension of the paper-feeding belt 130. In addition, the position of the tension wheel 142 can be adjusted to accommodate paper-feeding belts 130 of different lengths, ensuring that the tension of the paper-feeding belt 130 is within a suitable range. Furthermore, the support rod assembly 300 can support the carton skin, which on the one hand reduces the risk of the carton skin collapsing due to its softness, and on the other hand, allows the front end of the carton skin to tilt downwards, making it easier for the carton skin to be folded out through the gap between the paper stop 410 and the conveying part 131.
