Description

Technical Field

[0001] The utility model relates to the field of papermaking machines, in particular to a water receiving tray device capable of quickly replacing a forming net. Background Art

[0002] In the papermaking process, the papermaking forming fabric is an important equipment for the production of household paper. It should be replaced 3 times a year according to the replacement cycle. Figure 1 The figure shows a conventional water tray assembly. A scraper 6' is installed on the front of the forming wire 3' to prevent water from being spun off the wire. The water tray 1' functions to both prevent water and collect moisture. The forming wire 3' is an annular structure and must be pulled in from the paper machine's copying side. The water tray 1' is required to collect the water after squeezing. However, existing water trays are limited in design and present the following problems:

[0003] The existing water collection pan for papermaking cannot be adjusted after being fixed by the mounting frame, which affects the overall water collection effect. In addition, the water collection pan needs to be replaced every 4 months. Frequent disassembly and assembly of the scraper and water collection pan is time-consuming and labor-intensive, wasting time and manpower. Utility Model Content

[0004] Purpose of the utility model: The utility model provides a water receiving tray device that can quickly replace the forming net, which solves the problem of replacing the forming net without moving the water receiving tray and improves work efficiency.

[0005] Technical solution: The utility model proposes a water receiving tray device for quickly replacing a forming net, comprising a net water receiving tray, a forming net, a scraper fixing frame and a net scraper; the scraper fixing frame is provided on the net water receiving tray, and the net scraper is fixed to the front of the net water receiving tray through the scraper fixing frame, and the forming net is put in from the scooping side of the net water receiving tray and is transmitted through guide rollers and forming rollers; a step-shaped incision is provided at the lower end of the scooping side of the net water receiving tray, and the bottom of the forming net is located in the step-shaped incision near the side of the net water receiving tray, and a frame is provided on the front side of the forming net, a gap is formed between the scraper fixing frame and the frame, and the side of the forming net near the water receiving tray passes through the gap.

[0006] Preferably, there are a plurality of guide rollers, and the forming net reciprocates around the plurality of guide rollers, wherein a guide roller that cooperates with the bottom of the forming net and is close to one side of the water receiving tray is located in the step-shaped incision.

[0007] Preferably, the web scraper is fixed to the scraper fixing frame side end via a scraper fixing screw.

[0008] Preferably, the forming net is an annular structure.

[0009] Preferably, the scraper fixing frame has a scraping side end extending out of the wire water receiving tray.

[0010] Beneficial effect: The utility model reserves space for replacing the forming net by changing the shape structure of the scraper fixing frame and the net water receiving tray. Without moving the net scraper and the net water receiving tray, the forming net can be put in from the side of the net water receiving tray, which saves manpower time, reduces costs and improves economic benefits. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 It is a structural diagram of a water receiving tray device in the prior art;

[0012] Figure 2 This is a schematic diagram of a water receiving tray device for quickly replacing a forming net according to the present invention. DETAILED DESCRIPTION

[0013] Combine Figure 2 The embodiments of the present invention are further described.

[0014] The utility model provides a water-collecting tray device for quickly replacing a forming net. The device comprises a net water-collecting tray 1, a scraper fixing screw 2, a forming net 3, a scraper fixing frame 4, a frame 5, a net scraper 6, a guide roller 7, and a forming roller 8. The scraper fixing frame 4 is mounted on the net water-collecting tray 1 and secured to the net water-collecting tray 1 via the scraper fixing screw 2. A stepped cutout 9 is provided at the lower end of the net water-collecting tray on the sweeping side, with a 20 cm width for cutting steel plates to reserve space for the forming net. The drive side of the scraper fixing frame 4 serves as a positioning device and is fixed to the net water-collecting tray. The scraper fixing frame extends beyond the forming net. The net scraper 6 is secured to the scraper fixing frame 3 on the sweeping side via the scraper fixing screw 2. The forming net 3 is driven by the guide roller 7 and the forming roller 8, which cooperate with each other. A frame 5 is also provided on the front side of the forming net.

[0015] When the forming net 3 needs to be replaced, it is simply placed from the scraping side of the wire water receiving tray 1 into the stepped cutout 9 of the wire water receiving tray 1 and then transferred between the guide roller 7 and the forming roller 8. The scraper and the water receiving tray can be moved without moving the scraper and the wire water receiving tray, and the forming net can be placed from the scraping side of the wire water receiving tray, thus reducing manpower and time, lowering costs, and improving economic benefits.
