Abstract
Description
Technical Field
[0001] This utility model relates to the field of waste paper treatment technology, and more specifically to a pulping waste paper feeding and shearing device. Background Technology
[0002] In the operation of existing waste paper pulping feeding chain plate machines, each bundle of waste paper needs to have its wires cut by a wire cutter before it can be fed. Existing waste paper bale wire cutters on the market have technical problems such as poor cutting efficiency, easy bending of the output shaft of the cutting cylinder, and easy deformation of the guide rail, resulting in poor cutting performance and high failure rate. Utility Model Content
[0003] 1. Technical problem to be solved by the utility model
[0004] In view of the above-mentioned defects of the waste paper bale wire cutting machine in the prior art, this utility model provides a pulp waste paper feeding and wire cutting device, which improves the cutting efficiency of the binding wire of waste paper bales by the coordinated operation of the pushing cylinder and the cutting cylinder.
[0005] 2. Technical Solution
[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows:
[0007] A waste paper feeding and wire cutting device includes a side blade holder, a pushing cylinder, a shearing cylinder, a shearing blade toothed array, a support, and a guide rail fixed laterally in the support. The side blade holder is slidably connected to the guide rail. The output end of the pushing cylinder is connected to the back side of the side blade holder, and the fixed end is detachably connected to the support. The output end of the shearing cylinder is connected to a fixed blade toothed seat, and the fixed end is connected to the side blade holder. The shearing blade toothed array includes vertical fixed blade teeth and moving blade teeth. The fixed blade teeth are fixedly connected to the front side of the side blade holder, and the moving blade teeth are connected to the fixed blade toothed seat. In actual use, the pushing cylinder laterally presses the waste paper bale, and the shearing cylinder drives the moving blade teeth to rise and fall to achieve staggered shearing with the fixed blade teeth. The two work together to improve the shearing efficiency for the binding wire of the waste paper bale.
[0008] Further technical solutions include baffles that press firmly against the sides of the waste paper bales to reduce their displacement.
[0009] A further technical solution involves connecting the output spindle of the push cylinder to the back side of the side tool holder via universal joint two. This utilizes the weight of the entire side tool holder, preventing tilting and offset during cylinder extension and retraction, thus avoiding cylinder bending and deformation. The fixed end is detachably connected to the bracket via universal joint one, which serves as an auxiliary moving support and is not locked in place.
[0010] A further technical solution involves installing the universal joint at the upper half of the side tool holder, utilizing the weight of the entire side tool holder to provide a balancing compensation effect when the cylinder pushes forward.
[0011] A further technical solution involves connecting the side tool holder to the guide rail via rollers, making lateral pushing easier.
[0012] 3. Beneficial effects
[0013] Compared with the prior art, the technical solution provided by this utility model has the following advantages:
[0014] This utility model's waste paper feeding and shearing device is labor-saving and highly efficient in shearing operations. The main shaft joint at the front end of the hydraulic cylinder uses a universal joint to ensure that the side blade holder is vertically downward, reducing offset that could cause the hydraulic cylinder to bend and deform. The fixed end support of the hydraulic cylinder uses an auxiliary movable support instead of a locking fixation, effectively avoiding damage caused by excessive hydraulic cylinder movement. In addition, a fixed baffle is added to the foundation opposite the side blade holder to improve the stress stability during waste paper bale shearing. Attached Figure Description

[0017] To further understand the content of this utility model, a detailed description of the utility model is provided in conjunction with the accompanying drawings.
[0018] Example 1
[0019] The pulping waste paper feeding and shearing device in this embodiment, such as Figure 1 As shown, the device includes a side blade holder 3, a push cylinder 4, a shearing cylinder 5, shearing blade teeth 7, a bracket 1, and a guide rail 2 horizontally fixed in the bracket 1. The side blade holder 3 is slidably connected to the guide rail 2. The output end of the push cylinder 4 is connected to the back side of the side blade holder 3, and the fixed end is detachably connected to the bracket 1. The output end of the shearing cylinder 5 is connected to the fixed blade tooth seat 6, and the fixed end is connected to the side blade holder 3. The shearing blade teeth 7 includes vertical fixed blade teeth and moving blade teeth, with at least two vertical rows of teeth. The fixed blade teeth are fixedly connected to the front side of the side blade holder 3, and the moving blade teeth are connected to the fixed blade tooth seat 6. The tooth ends of the two rows of teeth are flush.
[0020] In this embodiment of the pulping waste paper feeding and wire cutting device, the pushing cylinder 4 laterally presses the waste paper bale 10, and the shearing cylinder 5 drives the moving blade tooth row to rise and fall to achieve staggered shearing with the fixed blade tooth row. The two work together to improve the shearing efficiency for the binding wire of the waste paper bale. The operation is labor-saving and highly automated.
[0021] Example 2
[0022] The pulping waste paper feeding and shearing device in this embodiment has the same basic structure as in embodiment 1, with the difference or improvement being that: the guide rail 2 is preferably channel steel; such as Figure 1 As shown, it also includes a baffle 11 that is pressed against the side of the waste paper bale 10 to reduce the displacement of the waste paper bale 10 and improve the stress stability of the waste paper bale 10 during shearing. The output end spindle of the push cylinder 4 is connected to the back side of the side blade holder 3 through universal joint 2 9. This allows the side blade holder 3 to utilize its own weight, preventing tilting and offset during cylinder extension and retraction, thus reducing cylinder bending and deformation. The fixed end is detachably connected to the bracket 1 through universal joint 1 8. Universal joint 1 8 serves as an auxiliary moving support and is not locked to avoid damage due to excessive cylinder movement. The installation height of universal joint 1 8 is 1 / 3 of the way from the highest point of the upper half of the side blade holder 3, which can fully utilize the weight of the entire side blade holder 3 and play a balancing compensation role when the cylinder pushes forward, effectively preventing the channel steel from bending. The side blade holder 3 is connected to the guide rail 2 by rollers 12, making lateral pushing more effortless.
[0023] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention. The actual structure and manufacturing steps are not limited to these. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
