Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of paper processing machinery, and specifically relates to a paper storage and waste sheet removing device for household paper production. BACKGROUND

[0002] In the production process of household paper, the storage, conveying and processing of unqualified products constitute an indispensable important part of the production process. These links not only directly relate to the operation efficiency of the production line, but also deeply affect the quality and cost-effectiveness of the final product. However, when dealing with these key tasks, traditional equipment generally exposes a series of problems such as low efficiency, complex operation and difficulty in recycling waste paper. These problems are increasingly prominent in production practice and need to be solved through technological innovation. Secondly, paper transfer is a common operation on the production line. Traditional turnover equipment often uses mechanical arms or rollers and other physical structures. These devices are prone to damage the paper during processing, especially thin paper or sensitive material paper. At the same time, the waste removal process of unqualified products is often inefficient, mainly relying on manual waste removal and difficult to avoid the confusion of waste paper and qualified products.

[0014] In order to facilitate understanding of the utility model, the utility model is more comprehensively described below with reference to the drawings. The preferred embodiments of the utility model are shown in the drawings. However, the utility model can be realized in many different forms, and is not limited to the embodiments described herein. The purpose of providing these embodiments is to make the disclosure of the utility model more thorough and comprehensive.

[0015] Referring to the drawings Figures 1-3 As shown in the drawings, in the embodiment, a paper storage and waste removing device for household paper production includes a first conveying unit 1 and a second conveying unit 2 distributed forward and backward along the paper conveying direction, a clamping and overturning mechanism 3 and a waste collecting and paper receiving platform 4. Through the cooperative work of various components, the storage, transfer and waste removal of paper stacks are completed. The first conveying unit 1 and the second conveying unit 2 both adopt a bearing conveying belt for stable and continuous conveying of paper stacks. This design not only has a simple structure and is easy to maintain, but also can effectively reduce the damage of paper stacks during conveying.

[0016] In this embodiment, the clamping and flipping mechanism 3 is located between the first conveying unit 1 and the second conveying unit 2, and is used to flip the paper stack from the first conveying unit 1 and clamp it onto the second conveying unit 2. Specifically, the clamping and flipping mechanism 3 of this embodiment has a pair of parallel clamping plates 31 and a clamping drive unit 32 for driving the clamping plates 31 to open, close and flip. Thus, the clamping drive unit 32 is used to drive the opening and closing and flipping actions of the clamping plates 31. Under normal circumstances, the pair of clamping plates 31 are in a horizontally open state, and the lower clamping plate 31 is lower than or flush with the conveying surfaces of the first conveying unit 1 and the second conveying unit 2, so that the paper stack can be smoothly fed into or out of the gap between the two clamping plates 31 under the drive of the first conveying unit 1 and the second conveying unit 2; in addition, the pair of clamping plates 31 are in a clamped state, stably clamping the paper stack to avoid damage or falling off the paper during the flipping process, and the clamping drive unit 32 drives the clamping plates 31 to perform a 180° flipping action to complete the transfer operation of the paper stack. This cycle is repeated to realize the continuous transfer of the paper stack.

[0017] Furthermore, the clamping and flipping mechanism 3 of this embodiment can also be flipped to an inclined state, so that a paper drop gap is formed between the end of the first conveying unit 1 and the clamping and flipping mechanism 3 (hereinafter referred to as the attached document). Figure 1 For example, under the drive of the clamping and feeding drive unit 32, the clamping plate 31 rotates counterclockwise by 45°, so that the gap formed between the bottom surface of the clamping plate 31 and the end of the first conveying unit 1 serves as the paper drop gap. This allows the defective paper stacks carried by the first conveying unit 1 to fall through the paper drop gap, effectively preventing the defective paper stacks from being transferred to the second conveying unit 2. After the defective paper stacks fall, the clamping and feeding flipping mechanism 3 can be flipped to a horizontal state to continue normal flipping and clamping operations.

[0018] In this embodiment, the clamping drive unit 32 includes a turntable and two sets of guide posts parallel to each other on the end face of the turntable. The two clamping plates 31 are slidably sleeved on the two guide posts. Thus, the output end of a preset rotary motor (not shown in the figure) acts on the turntable to drive the turntable and the two clamping plates 31 to rotate synchronously. The extension end of a preset cylinder or hydraulic cylinder (not shown in the figure) acts on the two clamping plates 31 to perform opposing opening and closing actions, thereby realizing the clamping drive unit 32 driving the clamping plates 31 to perform opposing opening and closing and flipping actions.

[0019] In the embodiment, the waste receiving platform 4 is arranged below the pinch turn-over mechanism 3, and is used to receive the stack of unqualified paper falling from the first conveying unit 1 through the paper falling gap. The waste receiving platform 4 is provided with a directional waste conveying belt 41, and the received stack of unqualified paper is timely sent out by the waste conveying belt 41. The waste conveying belt 41 is further provided with guide blocks 42 arranged in an inclined manner with the upper part being narrow and the lower part being wide. The design of the guide blocks 42 can guide the waste paper to slide along a predetermined path to the waste conveying belt 41, so as to avoid the accumulation or omission of the waste paper on the platform.

[0020] The above-mentioned embodiments are only the preferred embodiments of the present application, and do not limit the present application in any form. Any skilled person in the art can make more possible changes, decorations or modifications to the technical scheme of the present application by using the disclosed technical contents without departing from the scope of the technical scheme of the present application. Therefore, any equivalent changes and equivalent modifications made according to the idea of the present application should be covered in the protection scope of the present application.
