Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, and in particular to a ring-shaped felt needle punching machine. Background Technology

[0002] During operation, the needle-punching machine for circular felt blankets operates by a needle-punching drive mechanism that, driven by power, moves a push rod up and down, which in turn moves thousands of grooved needles on the needle plate up and down. Simultaneously, the power output shaft of the needle-punching drive mechanism, via chain drive, rotates a feed roller, which in turn moves the felt blanket to be needled forward. Because the needle plate has thousands of needles, when a needle pierces the felt blanket, it is stopped by the needle; when the needle is lifted, the elastic felt blanket, under the action of the feed roller, lurches forward, advancing one step at a time, in a continuous cycle.

[0003] Because there are many needles on the needle plate, some needles are slightly tilted or slightly bent, resulting in an unsatisfactory uniformity of the needles. Since the existing feed pitch is fixed, obvious strip marks extending along the blanket will be left on the blanket corresponding to the irregular areas of the needles, resulting in an uneven appearance of needles and affecting the quality of the blanket. Utility Model Content

[0004] In view of this, the present invention provides a ring-shaped felt needle punching machine, the main purpose of which is to make the feeding step distance continuously change, improve the needle punching appearance of the blanket, and improve the quality of the blanket.

Detailed Implementation

[0036] To further illustrate the technical means and effects adopted by this utility model to achieve its intended purpose, the specific implementation methods, structures, features, and effects according to this utility model application are described in detail below with reference to the accompanying drawings and preferred embodiments. In the following description, different "embodiments" or "embodiments" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.

[0037] like Figure 1 and Figure 2 As shown in the figure, an embodiment of the present invention discloses a ring-shaped felt blanket needle punching machine, comprising: a frame 1, a needle punching mechanism 2, a needle punching drive mechanism 3, a transmission mechanism 4, a support bed 5, a feeding roller 6, and a stretching roller 7; the frame 1 is a frame structure. The needle punching mechanism 2 is mounted on the frame 1, and a needle plate is mounted on the needle punching mechanism 2, with needles mounted on the needle plate; the needle plate is driven up and down by the needle punching drive mechanism 3 to realize the needle punching action on the felt blanket; the needle punching drive mechanism 3 is mounted on the frame 1 and is connected to the needle punching mechanism 2 for driving the needle punching mechanism 2 to move.

[0038] The transmission mechanism 4 includes: a drive wheel 4-1, an eccentric wheel 4-2, a tensioning assembly, a first transmission wheel 4-4, and a second transmission wheel 4-5. The drive wheel 4-1 is rotatably mounted on the frame 1 and is connected to the needle-punching drive mechanism 3. The drive wheel 4-1 can be mounted on the power output shaft of the needle-punching drive mechanism 3 for power output. The eccentric wheel 4-2 is rotatably mounted on the frame 1, causing the rotational speed of the first transmission wheel 4-4 to continuously change, which in turn causes the rotational speed of the feed roller 6 to continuously change via the second transmission wheel 4-5. Preferably, the eccentric wheel 4-2 is provided with multiple shaft holes. The distance between the multiple shaft holes and the center of the eccentric wheel 4-2 is different, and the magnitude of the rotational speed change is proportional to the eccentricity. A suitable shaft hole can be selected as needed.

[0039] Preferably, the eccentric wheel 4-2 and the driving wheel 4-1 transmit power according to a predetermined transmission ratio; the predetermined transmission ratio is a non-integer multiple to achieve a suitable speed change cycle.

[0040] The tensioning assembly includes a tensioning bracket and a tensioning wheel 4-3. The tensioning bracket is oscillatingly mounted on the frame 1. A tensioning spring is installed between the tensioning bracket and the frame 1. The tensioning wheel 4-3 is rotatably mounted on the tensioning bracket. The tensioning wheel 4-3 maintains continuous tension on the drive wheel 4-1, eccentric wheel 4-2, drive wheel 4-4, and tensioning wheel 4-3, ensuring reliable transmission. Drive wheel 4-4 is rotatably mounted on the frame 1. The drive wheel 4-1, eccentric wheel 4-2, drive wheel 4-4, and tensioning wheel 4-3 are connected by a drive belt or drive chain. Drive wheel 4-5 is mounted on the same shaft as drive wheel 4-4, enabling synchronous rotation. Drive wheel 4-5 outputs a continuously changing rotational speed.

[0041] The support bed 5 is mounted on the frame 1, below the needle punching mechanism 2. The feed roller 6 is pivotally mounted on the frame 1, located on one side of the support bed 5, and is used to drive the felt blanket. The feed roller 6 is connected to the transmission wheel 4-5 so that the speed change of the feed roller 6 is synchronized with the transmission wheel 4-5. The tension roller 7 is pivotally mounted on the frame 1, located on the other side of the support bed 5. The tension roller 7 is detachably mounted on the frame 1. The relative position of the tension roller 7 and the frame 1 is adjustable to tighten the annular felt blanket. The tension roller 7 can be mounted on the frame 1 via a base. The base can slide relative to the frame 1 to move away from or closer to the feed roller 6 to tighten the annular felt blanket.

[0042] One embodiment of this utility model proposes a ring-shaped felt needle punching machine that allows the step distance to become variable, disrupting the original regular needle punching layout and causing the forward speed of the felt to change continuously. During each needle punching interval, the distance the felt travels is different, resulting in a more uniform needle punching density and improving the appearance and quality of the felt.

[0043] In this preferred embodiment, the drive wheel 4-1, eccentric wheel 4-2, tensioner wheel 4-3, and transmission wheel 4-4 are all sprockets, ensuring reliable transmission. More preferably, the eccentric wheel 4-2 has one more or one less tooth than twice the number of teeth on the drive wheel 4-1 to achieve a suitable rotational speed change cycle, adaptable to current production requirements. Alternatively, the eccentric wheel may have two more or two fewer teeth than twice the number of teeth on the drive wheel. Of course, other tooth ratios can be selected according to process requirements.

[0044] Preferably, the feed roller 6 and the transmission wheel 4-5 are connected by a transmission chain or belt; this ensures reliable transmission. Of course, other transmission methods are not excluded. Preferably, the transmission wheel 4-5 is a sprocket, ensuring reliable and precise transmission.

[0045] To further clarify, while the terms "first," "second," etc., may be used herein to describe various elements, these terms should not limit the elements. These terms are used only to distinguish one element from another. For example, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element; these terms are used only to distinguish one element from another.

Similarly, "element one," "element two," and so on do not represent the order of elements; these terms are used only to distinguish one element from another.
