Description

Technical Field

[0001] This utility model belongs to the field of paper slitting machine technology, specifically, it relates to an auxiliary support frame for the paper feeding end of a paper slitting machine. Background Technology

[0002] In the paper processing industry, the auxiliary support frame at the paper feeding end of the paper slitting machine is a key component to ensure stable paper roll feeding, but its traditional design has many defects, which seriously restricts the improvement of production efficiency.

[0003] Traditional paper slitting machines typically use a single-station auxiliary support frame at the paper feeding end, capable of supporting only one paper roll for feeding. When the paper roll runs out and needs to be replaced, the machine must be stopped, completely interrupting the feeding process. In high-frequency feeding scenarios, frequent shutdowns for roll changes accumulate significant production downtime, drastically reducing the paper slitting machine's continuous operating capacity. Furthermore, the paper roll positioning of traditional auxiliary support frames relies on manual adjustment. Operators must adjust each positioning component individually to secure the paper roll, which is not only labor-intensive but also prone to instability due to operational errors. This can cause paper shifting and wrinkling during feeding, affecting slitting accuracy and resulting in material waste.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0006] The auxiliary support frame for the paper feeding end of the paper slitting machine includes a base plate and a frame mounted on the base plate.

[0007] The frame is rotatably mounted with a multi-station turntable, and each station of the multi-station turntable is rotatably mounted with a positioning roller. The positioning roller is equipped with a positioning component, and the positioning component is used to automatically position the paper roll mounted on the positioning roller.

[0008] The positioning assembly includes three positioning plates. One end of each positioning plate is rotatably mounted on a positioning roller. A rocker arm is rotatably mounted on the side wall of the positioning plate. A slider is mounted at the end of the rocker arm. A synchronization plate is mounted at the end of the slider. The synchronization plate is slidably connected to a guide rail mounted on the side wall of the frame. A notch is provided at the bottom of the guide rail. A compression spring is installed between the synchronization plate and the positioning roller. The compression spring is used to automatically unlock the positioning assembly when the synchronization plate moves to the notch.

[0009] In a preferred embodiment of the present invention, the frame is provided with several pairs of through holes for reducing the weight of the frame, and a base is installed at the bottom of the base plate, the base being in the shape of a boss.

[0010] In a preferred embodiment of this utility model, a shifting motor is installed on the side wall of the frame, the output end of the shifting motor movably passes through the frame, and its output end is connected to the rotation center of the multi-station turntable.

[0011] In a preferred embodiment of this utility model, the positioning roller is provided with a receiving groove, and the size of the receiving groove is adapted to the positioning plate. The slider is slidably disposed in the receiving groove, and a circular plate is installed at the connection between the positioning roller and the multi-station turntable.

[0012] In a preferred embodiment of this utility model, a top rod is installed at the center of the synchronization plate, a ball is installed at the end of the top rod, the end of the ball is slidably connected to the guide rail, and the side wall of the notch is chamfered.

[0013] In a preferred embodiment of this utility model, a rod is installed on the synchronization plate, and a baffle is installed at the end of the rod. The baffle is movably inserted into a sliding cavity opened inside the positioning roller, and a compression spring is engaged between the end face of the baffle and the end face of the sliding cavity. The compression direction of the compression spring and the movement direction of the rod are both on the same straight line.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] This invention enables parallel operations of continuous paper feeding at the top station and simultaneous empty roll disassembly and new roll installation at the unloading station, avoiding the time wasted by "stopping to change rolls" in traditional single-station equipment. This significantly improves the continuous operation capability of the paper slitter, making it particularly suitable for high-frequency paper feeding scenarios. At the same time, the positioning component automatically completes the unfolding of the positioning plate at the working station and the storage at the unloading station by means of the elastic drive of the compression spring and the mechanical limit of the guide rail. Operators do not need to manually adjust the positioning structure; they only need to complete the paper roll loading and unloading at the unloading station. This simplifies the operation process, reduces the intensity of manual labor, and also reduces positioning deviations caused by improper manual operation.

[0016] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0024] like Figures 1 to 4 As shown, the paper feed end auxiliary support frame of the paper separator includes a base plate 2 and a frame 1 mounted on the base plate 2.

[0025] A multi-station turntable 4 is rotatably mounted on the frame 1, and a positioning roller 5 is rotatably mounted on each station of the multi-station turntable 4. A positioning component is mounted on the positioning roller 5, and the positioning component is used to automatically position the paper roll mounted on the positioning roller 5.

[0026] The positioning assembly includes three positioning plates 9. Each positioning plate 9 is rotatably mounted on a positioning roller 5 at one end. A rocker arm 10 is rotatably mounted on the side wall of the positioning plate 9. A slider 11 is mounted at the end of the rocker arm 10, and a synchronization plate 12 is mounted at the end of the slider 11. The synchronization plate 12 is slidably connected to a guide rail 7 mounted on the side wall of the frame 1. A notch 8 is provided at the bottom of the guide rail 7. A compression spring 18 is installed between the synchronization plate 12 and the positioning roller 5. The compression spring 18 is used to automatically unlock the positioning assembly when the synchronization plate 12 moves to the notch 8. This structural design, through the cooperation of the positioning plates 9, rocker arms 10, sliders 11, synchronization plates 12, guide rail 7, notch 8, and compression spring 18, achieves automatic unlocking of the positioning assembly, improving the convenience of operation.

[0027] like Figures 1 to 4 As shown in the specific embodiment, the frame 1 has several pairs of through holes to reduce its weight, and a base 3 is mounted on the bottom of the substrate 2. The base 3 is in the shape of a boss. The through holes of the frame 1 reduce its weight, save materials, and facilitate handling. The boss-shaped base 3 at the bottom of the substrate 2 enhances the overall stability of the device and prevents shaking during operation.

[0028] like Figures 1 to 4As shown, a shift motor 20 is further installed on the side wall of the frame 1. The output end of the shift motor 20 extends through the frame 1 and is connected to the rotation center of the multi-station turntable 4. The shift motor 20 provides power for the rotation of the multi-station turntable 4, realizing automatic switching of workstations without the need for manual rotation, thus improving the efficiency of workstation switching.

[0029] like Figures 1 to 4 As shown, the positioning roller 5 has a storage groove 15, and the storage groove 15 is adapted to the size of the positioning plate 9. The slider 11 is slidably disposed in the storage groove 15, and a circular plate 6 is installed at the connection between the positioning roller 5 and the multi-station turntable 4. The storage groove 15 can store the positioning plate 9 when it is not working, avoiding the positioning plate 9 being exposed and causing interference. The circular plate 6 enhances the stability of the connection between the positioning roller 5 and the multi-station turntable 4.

[0030] like Figures 1 to 4 As shown, a push rod 13 is installed at the center of the synchronization plate 12, and a ball bearing 14 is installed at the end of the push rod 13. The end of the ball bearing 14 is slidably connected to the guide rail 7, and the side wall of the notch 8 is chamfered. The cooperation between the push rod 13 and the ball bearing 14 reduces the friction between the synchronization plate 12 and the guide rail 7, and the chamfering of the notch 8 makes the synchronization plate 12 move more smoothly when it moves to the notch 8, reducing component wear.

[0031] like Figures 1 to 4 As shown, a rod 16 is mounted on the synchronization plate 12, and a baffle 17 is mounted at the end of the rod 16. The baffle 17 is movably inserted into a sliding cavity 19 inside the positioning roller 5, and a compression spring 18 is engaged between the end face of the baffle 17 and the end face of the sliding cavity 19. The compression direction of the compression spring 18 and the movement direction of the rod 16 are both on the same straight line. The cooperation of the rod 16, the baffle 17, the sliding cavity 19, and the compression spring 18 ensures that the elastic force of the compression spring 18 can effectively act on the synchronization plate 12, making the operation of the positioning assembly more reliable.

[0032] The implementation principle of the auxiliary support frame at the paper feeding end of the paper slitting machine in this embodiment is as follows:

[0033] The multi-station turntable 4 is driven to rotate by the shifting motor 20 on the side wall of the frame 1. The positioning rollers 5, which are evenly distributed on its edge, can switch to different stations with the turntable. The top is the working station for continuous paper feeding, and the notch 8 at the bottom of the guide rail 7 corresponds to the unloading station. Functional isolation is achieved through precise station division, and the paper roll is sleeved on the positioning rollers 5.

[0034] When in the top working position, the positioning roller 5 is in the paper feeding position along with the turntable, and the synchronization plate 12 maintains sliding contact with the guide rail 7 through the ball bearing 14 at the end of the push rod 13. At this time, the guide rail 7 forms a lateral limit on the synchronization plate 12, and the pressure is transmitted to the baffle 17 through the insert rod 16, causing the compression spring 18 in the slide cavity 19 to be in a compressed state. The spring's rebound force acts in the opposite direction on the slider 11 through the mechanical structure, driving the rocker arm 10 to rotate, forcing the three positioning plates 9 to unfold from the receiving slot 15 and radially and tightly press against the inner ring of the paper roll. This positioning state is maintained throughout the entire paper feeding process, ensuring that the paper roll does not deviate when pulled by the paper slitter, thus guaranteeing paper feeding accuracy.

[0035] When a paper roll needs to be replaced, the shifting motor 20 drives the multi-station turntable 4 to rotate, moving the positioning roller 5 of the roll to be replaced to the notch unloading station. At this time, the synchronization plate 12 moves with the positioning roller 5 to the notch 8 of the guide rail 7 (the chamfered design of the notch sidewall facilitates a smooth transition). The limiting effect of the guide rail 7 disappears, and the compression spring 18 releases the stored elastic force, pushing the baffle 17, the insertion rod 16, and the synchronization plate 12 to move away from the positioning roller 5. The displacement of the synchronization plate 12 drives the rocker arm 10 to rotate in the opposite direction through the slider 11, causing the positioning plate 9 to retract into the receiving slot 15, releasing the constraint on the paper roll. The operator can quickly complete the unloading of the empty roll and the installation of the new roll. During this process, the positioning roller of the top working station continues to feed paper normally, and the two do not interfere with each other.

[0036] After the roll change is completed, the multi-station turntable 4 rotates again, the positioning roller 5 leaves the notch unloading station, and the synchronization plate 12 re-engages with the guide rail 7 via the ball bearings 14. The compression of the guide rail 7 forces the synchronization plate 12 to move in the opposite direction, the insertion rod 16 drives the baffle 17 to compress the spring 18, and at the same time the slider 11 pulls the rocker arm 10 to re-unfold the positioning plate 9 (if switched to the top working station, it directly enters the positioning state; if in the transition station, it remains in a semi-retracted state). Through this mechanically linked automatic reset design, when the new paper roll switches to the top working station with the turntable, it can immediately enter a stable positioning state, ensuring the continuous operation of the paper slitting machine.
