Description

Technical Field

[0001] The utility model relates to the field of label materials, in particular to a material slot width adjusting device for a comma scraper coating machine. Background Art

[0002] When label material manufacturers process and produce label products, they need to apply ink or glue to the label tape. The comma scraper coater is one of the devices used to apply ink or glue to the label tape. The dustpan-shaped trough of the comma scraper coater contains ink or glue, and the dustpan-shaped trough is at an adjustable distance from the bottom roller. The label tape passes through the notch of the trough as the bottom roller rotates and is covered with ink or glue, and the excess ink or glue is scraped off by the comma scraper.

[0003] Since the width of the comma blade coater is fixed, while the width of the label tape is different, in order to meet the requirements of the same comma blade coater for ink and glue application on label tapes of different specifications, two blocks are usually designed and placed on both sides of the ink trough, and blocks of different thicknesses are selected for label tapes of different widths. This results in a large number of blocks, and the ink and glue application width cannot be accurately controlled.

[0004] Therefore, how to transform the existing comma blade coater at a lower cost to meet the actual needs of the enterprise is an urgent problem to be solved by technical personnel in this field. Summary of the invention

[0005] The purpose of the utility model is to provide a material trough width adjustment device for a comma scraper coater in view of the deficiencies in the prior art. The device has a simple structure and low modification cost, can accurately adjust the spacing between two baffle plates, adapt to label tapes of different widths, and meet the actual needs of enterprises.

[0006] The technical solution of the utility model is: a material trough width adjustment device of a comma scraper coater, comprising a material trough body, and also comprising a first material baffle plate and a second material baffle plate. One end of the first material baffle plate and the second material baffle plate corresponding to the bottom roller is provided with a first making way notch for the bottom roller, and the first material baffle plate and the second material baffle plate are fixedly provided with a guide column extending in a horizontal direction. The trough wall of the material trough body is provided with a guide hole extending in a horizontal direction. The first material baffle plate and the second material baffle plate are arranged in the material trough body, and cooperate with the gap of the bottom roller through the corresponding first making way notch. The guide column on the material baffle plate passes through the guide hole on the corresponding trough wall, so that the material baffle plate is slidably fitted in the trough bottom of the material trough body, and also comprises two rotating shafts, the rotating shaft threadedly cooperates on the trough wall of the material trough body, one end of the rotating shaft extends out of the material trough body, a handle is fixedly installed, and a boss is provided at the other end, and idlingly cooperates in the corresponding material baffle plate to drive the corresponding material baffle plate to move.

[0007] The upper ends of the first baffle plate and the second baffle plate are both provided with a second making way notch for making way for the comma scraper.

[0008] It also includes a scale, one end of which is fixedly connected to the corresponding material baffle plate, and the other end of which extends out of the trough wall of the trough body, and a scale section is arranged on the extended section.

[0009] The first material baffle plate and the second material baffle plate are both made of plastic.

[0010] The number of guide posts on the first material baffle plate and the second material baffle plate are both two, and are distributed on both sides of the corresponding rotating shaft.

[0011] The outer side walls of the first material baffle plate and the second material baffle plate are both provided with dovetail opening grooves, and the boss of the rotating shaft is arranged in the dovetail opening groove of the corresponding material baffle plate to form an idle fit.

[0012] The above technical solution has the following beneficial effects:

[0013] 1. The trough width adjustment device of the comma blade coater includes a trough body for containing ink or glue, and obviously, the discharge end of the trough body is matched with the gap of the bottom roller, and the gap is adjustable. The first and second material baffle plates are fixedly provided with guide columns extending in a horizontal direction, and the groove wall of the trough body is provided with guide holes extending in a horizontal direction. The first and second material baffle plates are arranged in the trough body, and cooperate with the gap of the bottom roller through the corresponding first gaps. The guide columns on the material baffle plates pass through the guide holes on the corresponding groove walls, so that the material baffle plates are slidably fitted on the groove bottom of the trough body. That is, the spacing distance between the first and second material baffle plates is adjustable, so that the space width of the trough body for holding ink or glue is adjustable to adapt to label tape products of different widths. The first and second material baffle plates are matched with the gap of the bottom roller towards one end of the bottom roller, and can also effectively prevent ink or glue from leaking out, thereby ensuring the normal operation of the coating machine. It also includes two rotating shafts, which are threadedly engaged on the trough wall of the trough body. One end of the rotating shaft extends out of the trough body and is fixedly equipped with a handle. The other end is provided with a boss and idlingly engaged in the corresponding baffle plate to drive the corresponding baffle plate to move. That is, by rotating the rotating shaft, the length of the shaft section of the rotating shaft located in the trough body can be adjusted, thereby driving the corresponding baffle plate to move steplessly, thereby achieving the purpose of accurately controlling the distance between the two baffle plates.

[0014] 2. The upper ends of the first baffle plate and the second baffle plate are both provided with a second clearance notch for making way for the comma scraper, that is, the upper edges of the first baffle plate and the second baffle plate form a gap fit with the comma scraper, so that the ink or glue scraped off by the comma scraper falls back between the first baffle plate and the second baffle plate for recycling.

[0015] 3. It also includes a scale, one end of which is fixedly connected to the corresponding material baffle plate, and the other end extends out of the trough wall of the trough body. A scale section is set on the extended section to facilitate the staff to calculate the interval distance between the two material baffle plates.

[0016] 4. There are two guide posts on the first baffle plate and the second baffle plate, which are distributed on both sides of the corresponding rotating shaft, so as to improve the movement stability of the first baffle plate and the second baffle plate.

[0017] 5. The outer side walls of the first baffle plate and the second baffle plate are both provided with dovetail opening grooves, and the boss of the rotating shaft is arranged in the dovetail opening groove of the corresponding baffle plate to form an idle fit, so that the processing cost is low and it is convenient to assemble the baffle plate.
