Description

Technical Field

[0001] The utility model relates to the technical field of sewing, in particular to a high-quality straight-line four-head dotting machine. Background Art

[0002] Most existing linear dotted fencing strips are machine-processed to create the linear pattern first, then the dot pattern. This two-step process reduces efficiency by half. After the linear pattern is completed, the strip must be removed and reinstalled on the dot machine, increasing the time required to change machines. Furthermore, using two machines to create the finished product reduces quality. Consequently, existing fencing strips suffer from low efficiency, inconsistent quality, high costs from multiple processes, and significant space requirements when producing both linear and dotted patterns. Utility Model Content

[0003] The utility model provides a high-quality straight line four-head dotting machine, which solves the technical problem of low efficiency in the prior art when making straight line patterns and dotting patterns on surrounding strips.

[0004] In order to solve the above problems, the utility model provides a high-quality straight-line four-head dotting machine adopts the following technical solutions:

[0005] A high-quality linear four-head dotting machine includes a box body, in which a dotting mechanism and a linear mechanism are arranged at intervals along the left and right directions. The linear mechanism is arranged on the right side of the dotting mechanism and the material is transported from right to left and passes through the linear mechanism and the dotting mechanism in sequence. A synchronization mechanism is provided between the linear mechanism and the dotting mechanism. The synchronization mechanism includes a synchronization rod and a control terminal that can be raised and lowered in the up and down directions. The control terminal is connected to the dotting mechanism and the linear mechanism signals to control the start and stop of the dotting mechanism and the linear mechanism. The part of the material between the linear mechanism and the dotting mechanism passes under the synchronization rod and the upper end surface of the material is always in contact with the synchronization rod. When the synchronization rod is in the lowest position, the control terminal can control the linear mechanism to stop operation; when the synchronization rod is in the highest position, the control terminal can control the linear mechanism to start operation.

[0006] The beneficial effect is: when the high-quality linear four-head dotting machine of the utility model is in use, the material passes under the synchronization rod after the linear mechanism operates. Since the linear mechanism operates faster, the material drops at this time, and the synchronization rod drops at the same time until the synchronization rod drops to the lowest position. The control terminal controls the linear mechanism to stop operating. At this time, the dotting mechanism continues to operate and causes the material to be transported to the left, so that the material drives the synchronization rod to rise. Until the synchronization rod rises to the highest position, the control terminal controls the linear mechanism to start operating. When the high-quality linear four-head dotting machine of the utility model is in use, the dotting mechanism and the linear mechanism are linked together by the synchronization mechanism, so that the dotting mechanism and the linear mechanism can operate on the same material at the same time, and avoid accidents caused by the lack of coordination between the dotting mechanism and the linear mechanism due to different working speeds.

[0007] Furthermore, a material receiving mechanism is provided on the left side of the dotting mechanism. The material receiving mechanism includes a material receiving rack, a material receiving motor, a reducer connected to the output shaft of the material receiving motor, and a material receiving roller connected to the reducer. The material is wound around the material receiving roller after being dotted by the dotting mechanism.

[0008] Beneficial effects: simple structure and easy to collect materials.

[0009] Furthermore, a synchronization mechanism is provided between the dotting mechanism and the material receiving mechanism and is capable of controlling the start and stop of the material receiving motor.

[0010] Beneficial effect: ensuring the stable material collection of the material collection mechanism.

[0011] Furthermore, the synchronization mechanism includes two guide rods spaced apart in the front-to-back direction, each guide rod is slidably equipped with a sliding block, and the synchronization rod is arranged between the two sliding blocks and extends in the front-to-back direction.

[0012] Beneficial effects: simple structure, easy maintenance and installation.

[0013] Furthermore, two cloth pulling mechanisms are provided between the two synchronization mechanisms. The two cloth pulling mechanisms are respectively placed on the left and right sides of the dotting mechanism. The cloth pulling mechanism includes an active roller and a passive roller arranged at intervals along the up and down directions. The active roller and the passive roller are both rotatably assembled in the box body and the active roller and the passive roller are used to clamp the material. The active roller is connected to a drive motor to drive the active roller to rotate to drive the material to move.

[0014] Beneficial effect: Controls the spacing between the dots of the dotting mechanism.

[0015] Furthermore, the dotting mechanism includes a first head group and a second head group located on the left side of the first head group. The first head group and the second head group are arranged at intervals along the left and right directions and each includes two dotting heads arranged at intervals along the front and back directions. The two dotting heads on the second head group can move synchronously along the left and right directions and can also move along the front and back directions. The two dotting heads on the first head group can move along the front and back directions.

[0016] Beneficial effect: the dotting mechanism can produce different patterns.

[0017] Furthermore, the first head assembly includes a first linear module and two dotting heads slidably assembled on the first linear module.

[0018] Beneficial effect: It is convenient for the dotting mechanism to produce different styles.

[0019] Furthermore, the second head group includes a slide rail, a second linear module slidably assembled on the slide rail along the left-right direction, and two dotting heads slidably assembled on the second linear module along the front-back direction.

[0020] Beneficial effect: It is convenient to adjust the distance between the first head group and the second head group, so that the dotting mechanism can produce different patterns.

[0021] Furthermore, it also includes three cloth pressing mechanisms, which are respectively placed on the right side of the first head group, between the first head group and the second head group, and on the left side of the second head group. The cloth pressing mechanisms are used to clamp the material when the dotting head moves to prevent the material from moving.

[0022] Beneficial effect: It prevents the material from moving when the second head group moves and the dotting head moves, ensures the accuracy of material dotting and improves the dotting quality.

[0023] Furthermore, the cloth pressing mechanism includes a cloth pressing frame, a fixing plate fixed on the cloth pressing frame, a cloth pressing plate arranged on the cloth pressing frame and lifted up and down, and a cloth pressing cylinder, which is used to drive the cloth pressing plate to lift up and down.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0036] Any number of elements in the drawings is for illustration and not limitation, and any naming is for distinction only and does not have any limiting meaning.

[0037] The principle and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.

[0038] Embodiment 1 of a high-quality linear four-head dotting machine provided by the present utility model:

[0039] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown, a high-quality linear four-head dotting machine of the utility model includes a box body, wherein the length direction of the box body is defined as the left and right direction, and the box body is provided with a feeding mechanism 20, a linear mechanism 21, a synchronization mechanism, a cloth pulling mechanism, a cloth pressing mechanism, a dotting mechanism 22 and a material receiving mechanism.

[0040] The feeding mechanism 20 is arranged on the right side of the box body for supplying the material 6 to be processed.

[0041] The linear mechanism 21 is disposed on the left side of the feeding mechanism 20 to process a linear pattern on the material 6 conveyed by the feeding mechanism 20 .

[0042] The dotting mechanism 22 is disposed on the left side of the linear mechanism 21 to process dotting patterns on the material 6 conveyed by the linear mechanism 21 .

[0043] The dotting mechanism 22 includes a first head group and a second head group arranged on the left side of the first head group. The first head group and the second head group are arranged at intervals along the left and right directions and each includes two dotting heads 12 arranged at intervals along the front and back directions, and each dotting head 12 can be raised and lowered in the up and down directions.

[0044] The first head assembly includes a first linear module 13 extending in the front-to-back direction and two dotting heads 12 slidably assembled on the first linear module 13 in the front-to-back direction.

[0045] The second head assembly includes a slide rail 14 extending in the left-right direction, a second linear module 15 slidably mounted on the slide rail 14 in the left-right direction, and two dotting heads 12 slidably mounted on the second linear module 15 in the front-back direction.

[0046] The material receiving mechanism is located on the left side of the dotting mechanism 22 to wind and collect the material 6 delivered by the dotting mechanism 22. The material receiving mechanism includes a receiving frame 2, a receiving motor 3, a reducer 4 connected to the output shaft of the receiving motor 3, and a receiving roller 5 connected to the reducer 4. After the material 6 is dotted by the dotting mechanism 22, it is wound around the receiving roller 5.

[0047] The synchronization mechanism includes two guide rods 7 spaced apart in the front-to-back direction and a control terminal. Each guide rod 7 extends vertically and is slidably mounted with a sliding block 8. A synchronization rod 1 extending in the front-to-back direction is positioned between the two sliding blocks 8. The synchronization rod 1 has a maximum and minimum position. The control terminal is housed within the housing and includes two photoelectric sensors, one corresponding to the maximum and the other to generate a disconnection signal when the synchronization rod 1 reaches its maximum and minimum positions.

[0048] There are two synchronization mechanisms, which are respectively arranged between the linear mechanism 21 and the dotting mechanism 22 and between the dotting mechanism 22 and the material receiving mechanism.

[0049] When the two photoelectric sensors of the synchronization mechanism arranged between the linear mechanism 21 and the dot-marking mechanism 22 are in use, when the corresponding synchronization rod 1 is at the highest position, the corresponding photoelectric sensor can send a signal to start working of the linear mechanism 21; when the corresponding synchronization rod 1 is at the lowest position, the corresponding photoelectric sensor can send a signal to stop working of the linear mechanism 21.

[0050] When the two photoelectric sensors of the synchronization mechanism arranged between the dotting mechanism 22 and the material receiving mechanism are in use, when the corresponding synchronization rod 1 is at the highest position, the corresponding photoelectric sensor can send a signal to stop the material receiving motor 3 from working, and when the corresponding synchronization rod 1 is at the lowest position, the corresponding photoelectric sensor can send a signal to start the material receiving motor 3 from working.

[0051] There are two cloth pulling mechanisms, which are respectively placed on the left and right sides of the dotting mechanism 22. The cloth pulling mechanism includes an active roller 9 and a passive roller 10 arranged at intervals along the up and down directions. The active roller 9 and the passive roller 10 are both rotatably assembled in the box body and the active roller 9 and the passive roller 10 are used to clamp the material 6. The active roller 9 is transmission-connected to a drive motor 11 to drive the active roller 9 to rotate to drive the material 6 to move.

[0052] There are three cloth-pressing mechanisms, which are respectively located on the right side of the first head group, between the first head group and the second head group, and on the left side of the second head group. The cloth-pressing mechanisms are used to clamp the material 6 to prevent the material 6 from moving when the dotting head 12 moves. The cloth-pressing mechanism includes a cloth-pressing frame 16, a fixing plate 17 fixed to the cloth-pressing frame 16, a cloth-pressing plate 18 that is lifted and lowered on the cloth-pressing frame 16 in the vertical direction, and a cloth-pressing cylinder 19. The cloth-pressing cylinder 19 is used to drive the cloth-pressing plate 18 to rise and fall.

[0053] When a high-quality linear four-head dotting machine of the present invention is in use, the material 6 passes under the synchronization rod 1 after passing through the linear mechanism 21. Since the linear mechanism 21 operates faster, the material 6 drops at this time, and the synchronization rod 1 drops at the same time until the synchronization rod 1 drops to the lowest position. The control terminal controls the linear mechanism 21 to stop working. At this time, the dotting mechanism 22 continues to operate and transports the material 6 to the left, so that the material 6 drives the synchronization rod 1 to rise. Until the synchronization rod 1 rises to the highest position, the control terminal controls the linear mechanism 21 to start working.

[0054] The utility model discloses a high-quality linear four-head dotting machine. When in use, the dotting mechanism and the linear mechanism are linked together through a synchronization mechanism, so that the dotting mechanism and the linear mechanism can operate on the same material at the same time, and avoid the occurrence of accidents caused by the lack of coordination between the dotting mechanism and the linear mechanism due to different working speeds.

[0055] Embodiment 2 of a high-quality linear four-head dotting machine provided by the present utility model:

[0056] The main difference between it and Example 1 is that: in Example 1, a material receiving mechanism is also provided on the left side of the dotting mechanism, and the material receiving mechanism includes a material receiving rack, a material receiving motor, a reducer connected to the output shaft of the material receiving motor, and a material receiving roller connected to the reducer. The material is wound around the material receiving roller after being dotted by the dotting mechanism.

[0057] In this embodiment, no material collecting mechanism is provided, and the staff directly folds and collects the materials on the left side of the dotting mechanism.

[0058] Embodiment 3 of a high-quality linear four-head dotting machine provided by the present utility model:

[0059] The main difference between it and Example 1 is that in Example 1, a synchronization mechanism is also provided between the dotting mechanism and the material receiving mechanism and can control the start and stop of the material receiving motor.

[0060] In this embodiment, no synchronization mechanism is provided between the dotting mechanism and the material receiving mechanism. In this case, the material receiving roller adjusts the efficiency of collecting materials according to the working efficiency of the dotting mechanism.
