Description

Technical Field

[0001] The utility model relates to the technical field of carding machine accessories, in particular to a waste removing baffle at the cotton outlet of a carding machine. Background Art

[0002] According to what is known in the textile field, after carding, the carding machine processes cotton fibers into a blanket shape and conveys them outwards. During the conveying process, impurities and flying fluffs doped in the cotton fibers surround the peripheral of the blanket-shaped cotton. If not removed in time, the impurities will follow the blanket-shaped cotton into the next process, affecting the spinning quality or easily causing equipment damage.

[0003] In the prior art, a negative pressure pipe is installed on one side of the equipment, and the negative pressure pipe directly sucks the side of the carding machine outlet. The impurities are removed through the negative pressure at a single point on one side. However, the disadvantages of such waste removing equipment are as follows: the pressure value of the waste removing negative pressure cannot be accurately controlled. Because the waste removing process is single-point waste removing, in order to improve the efficiency, the negative pressure air pressure is usually increased. However, this method will restrict the movement of cotton fibers towards the negative pressure port, and even suck the fibers on one side of the cotton blanket into the negative pressure port, not only the waste removing is not thorough but also it will have the opposite effect and cause damage to the cotton blanket; moreover, the impurities located at the far end cannot be removed by the negative pressure port.

[0004] Aiming at the above disadvantages, the technical problem that needs to be solved urgently by those skilled in the art is: how to design a waste removing baffle at the cotton outlet of a carding machine, which can be modularly assembled, can set negative pressure ports at multiple points, and realize the external discharge of impurities through multiple negative pressure ports. Summary of the Utility Model

[0009] An insertion slot is arranged inside the negative pressure bin. A filter layer is inserted into the insertion slot, and the negative pressure source connection port is separated from the negative pressure slit by the filter layer.

[0010] An impurity removal device is inserted and arranged in the negative pressure bin. The impurity removal device includes an end cover. A force application handle is arranged on the end cover, and an insertion rod is arranged inside the end cover. A plurality of radially arranged steel wool balls are fixed on the insertion rod.

[0011] There are multiple insertion rods, and adjacent insertion rods are arranged at intervals. Such an interval setting is based on the standard that a person's finger can be inserted, and it shall not affect the cleaning of impurities on the insertion rods.

[0012] The upper surface of the impurity removal plate is inclined left and right with the midline as the boundary. The left and right ends of the impurity removal plate are lower than the height of the midline position.

Specific Embodiments

[0023] The present invention will be described in detail below through specific embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification; it should be noted, however, that the following specific embodiments do not technically limit the technical solution. Under the guidance of the following technical solution, those skilled in the art can further extend the technology. The protection scope of this patent application shall be subject to the claims.

[0024] Embodiment 1:

[0025] As shown in the attached drawings, a cleaning baffle at the cotton outlet of a carding machine includes a fixing plate 1 and a cleaning plate 2. The fixing plate 1 is used to connect with the side support frame 71 on the carding machine 7. For convenient locking and fixing, fixing seats 11 are provided at both left and right ends of the fixing plate 1. Lock and fix with Side support frame 71 through the fixing base 11. Usually, on the existing carding machine 7 The top surface of the side support frame 71 is designed in an arc shape. To improve the assembly stability, the fixing seat 11 is also arranged in an arc shape and fits with the top surface of the side support frame 71.

[0026] The cleaning plate 2 is connected to the fixing plate 1. Those skilled in the art can use the stamping and integral forming method to realize the bending and forming of the two. Negative pressure chambers 3 are respectively arranged at both left and right ends of the cleaning plate 2. The negative pressure chambers 3 are provided with negative pressure gaps 33 towards the edges of the cleaning plate 2. Each negative pressure chamber 3 is connected to a negative pressure pipe and provides negative pressure. For a more specific structure, the negative pressure pipe includes a main negative pressure pipe 6, side main pipes 61, and negative pressure branch pipes 62. The main negative pressure pipe 6 is connected to an external negative pressure fan. There are two side main pipes 61, which are respectively arranged in cooperation with the two negative pressure chambers 3. A number of negative pressure branch pipes 62 are connected to each side main pipe 61. A plurality of negative pressure source connection ports 63 are evenly arranged in the front and back of each negative pressure chamber 3. A negative pressure branch pipe 62 is fixed on each negative pressure source connection port 63. By connecting a plurality of negative pressure branch pipes 62 through a plurality of negative pressure source connection ports 63, multi-point suction in each negative pressure chamber 3 is realized, improving the cleaning efficiency.

[0027] Further, the upper surface of the impurity removal plate 2 is inclined left and right with the center line 20 as the boundary, that is, the left and right ends of the impurity removal plate 2 are lower than the height of the center line 20. Such a structure can form inclined surfaces on both sides of the center line, and granular impurities can flow to the left and right.

[0028] A diversion groove 21 is arranged on the upper surface of the impurity removal plate 2. The diversion groove 21 penetrates through the middle part and the left and right ends of the impurity removal plate 2. Fine granular impurities and cotton scraps at the bottom of the cotton blanket can pass through the diversion groove 21 during the walking of the cotton blanket and be sucked to the outside by negative pressure. This design effectively ensures that impurities in the middle area of the impurity removal plate 2, that is, in the middle part of the cotton blanket, can also be effectively cleaned.

[0029] Embodiment 2:

[0030] In Embodiment 1, it is effectively shown that the impurity removal baffle at the cotton outlet of this carding machine can recycle impurities at the bottom and side of the cotton blanket. However, if only through the above structure, the recycled impurities will enter the negative pressure fan through the pipeline. To avoid affecting the negative pressure source, the structure of the negative pressure bin 3 of the present utility model is improved. It can achieve impurity blocking and collection through the negative pressure bin 3. The specific structure for realizing the above functions is as follows:

[0031] A baffle 32 is arranged in the negative pressure bin 3. The negative pressure bin 3 is divided into a plug-in slot 34 and an impurity removal device fixing area 31 by the baffle. A filter layer 4 is inserted into the plug-in slot 34. The filter layer 4 separates the negative pressure source connection port 63 from the negative pressure gap 33. The filter layer 4 is a plug-in type mesh structure component, which includes a frame 42. A filter mesh surface 41 is arranged inside the frame 42. A finger groove 43 is arranged at the end of the frame 42. The user can pull out the filter layer 4 as a whole by applying force to the finger groove 43 for cleaning.

[0032] An impurity removal device 5 is inserted and arranged in the impurity removal device fixing area 31. The impurity removal device 5 includes an end cover 53. A force application handle 54 is arranged on the end cover 53. An insertion rod 51 is arranged inside the end cover 53. A plurality of radially arranged steel wool balls 52 are fixed on the insertion rod 51 as hanging objects, which can uniformly collect the flying flocs sucked by negative pressure and prevent impurities and flying flocs from entering the negative pressure equipment.

[0033] The insertion rods 51 are multiple and are arranged at intervals between adjacent insertion rods 51. Such an interval setting is based on the standard that a person's finger can be inserted, and it shall not be densely arranged to affect the cleaning of impurities on the insertion rods. The arrangement of the insertion rods 51 can improve the collection efficiency of cotton scraps.

[0034] After the above structure is set, a plurality of radially arranged steel wool balls 52 arranged on the insertion rod 51 can hook the cotton flocs in the negative pressure bin 3, and the user can regularly pull out the impurity removal device 5 for cleaning.

[0035] The utility model has a simple structure, is convenient to manufacture and install, can be installed and used on the existing carding machine, and has an obvious impurity removal effect, and is an ideal impurity removal baffle at the cotton outlet of the carding machine.
