[0064] The present invention will be further described in detail below with reference to the accompanying drawings.

[0065] The following combines the attached Figures 1-10 A detailed description of the first embodiment, a zipper manufacturing process, includes the following steps:

[0066] S1. Prepare zipper strips of the required width;

[0067] S2. Use a chain tooth processing device to process zipper teeth;

[0068] S3. Install the processed zipper teeth onto the prepared cloth strip.

[0069] The following will be described in detail with reference to Figure 1 ., 2 ., 3, and 4. The chain tooth processing device includes a fixed plate 101, a contact frame 102, a limit frame 103, and a tooth pressing member. The contact frame 102 is fixedly connected to the fixed plate 101 by welding, the limit frame 103 is fixedly connected to the contact frame 102 by welding, and a tooth pressing member capable of performing tooth processing on a plate is fixedly connected to the fixed plate 101 by welding.

[0070] The fixed plate 101 plays a bearing role, providing a fixed space for the entire device. Four corners below the fixed plate 101 are fixedly connected with heightening legs to fix the device at a certain height. The plate to be processed will contact the contact frame 102. There is a certain gap between the contact frame 102 and the limit frame 103, and the plate will pass through this gap. When the chain teeth are processed, they will contact the limit frame 103. The limit frame 103 plays a limiting role, allowing the processed plate to slide along the limit frame 103 to prevent the processed plate from running around randomly and interfering with the collection of the plate. Notches are provided on both sides above the limit frame 103. After the plate contacts the contact frame 102, the tooth pressing member rotates to contact the plate to realize the extrusion of the plate. At this time, the plate can be pressed and processed according to the grooves on the tooth pressing member, completing the cutting of the plate and the processing of the chain teeth.

[0071] The following will be described in detail with reference to Figure 1 and 3 in detail. The tooth pressing member includes a vertical ear plate 201, a pressing wheel 202, and a processing groove 203. The vertical ear plate 201 is fixedly connected to the fixed plate 101 by welding. The pressing wheel 202 is rotatably connected to the vertical ear plate 201 by a shaft. A plurality of processing grooves 203 are uniformly arranged in the circumferential direction of the pressing wheel 202.

[0072] The vertical ear plate 201 plays a bearing and supporting role. A reduction motor I is fixedly connected to the vertical ear plate 201. The output shaft of this reduction motor I is fixedly connected to the pressing wheel 202. After starting this reduction motor I, the pressing wheel 202 can be driven to rotate. The pressing wheel 202 contacts the contact frame 102, and the plate will enter the device from the connection between the pressing wheel 202 and the contact frame 102. The plate is cut and processed by a plurality of processing grooves 203. The shape of the processing groove 203 is the same as the shape of the zipper teeth. After the plate is connected to the contact between the pressing wheel 202 and the contact frame 102, a plurality of processing grooves 203 will intermittently contact the plate. At this time, a plurality of processing grooves 203 perform pressing and cutting processing on the plate, completing the processing of the chain teeth.

[0073] According to the detailed description in the attached drawings of the specification, Figure 4 the chain tooth processing device further includes two limiting curved frames 301, and both of the two limiting curved frames 301 are fixedly connected to the vertical ear plates 201 by welding.

[0074] A channel is formed between the two limiting curved frames 301, and the plate to be processed passes through this channel. The outlet of this channel is located between the pressing wheel 202 and the contact frame 102. When the plate to be processed passes through the channel between the two limiting curved frames 301, it will directly enter the connection between the pressing wheel 202 and the contact frame 102 to realize the processing of the plate. Rotating notches are provided on both of the two limiting curved frames 301.

[0075] According to the detailed description in the attached drawings of the specification, Figure 4 the chain tooth processing device further includes two driving wheels I 302, and both of the two driving wheels I 302 are rotationally connected to the vertical ear plates 201 by shafts. The two driving wheels I 302 are respectively located within the two limiting curved frames 301.

[0076] Two reduction motors II are fixedly connected to the vertical ear plates 201. The output shafts of the two reduction motors II are respectively fixedly connected to the two driving wheels I 302. Starting the two reduction motors II can drive the two driving wheels I 302 to rotate. The two driving wheels I 302 play a role in transmission. The rotating two driving wheels I 302 can drive the plate located between the two limiting curved frames 301 to move. A plurality of transmission grooves are provided on both of the two driving wheels I 302. When the two groups of multiple transmission grooves contact the plate, a greater frictional force will be generated between the two driving wheels I 302 and the plate, which is convenient for driving the plate to move and enter between the pressing wheel 202 and the contact frame 102.

[0077] According to the detailed description in the attached drawings of the specification Figure 1 , 5 , 6 and 7, it further includes a limiting cutting device. A limiting cutting device capable of cutting the plate is fixedly connected to the fixing plate 101 by welding.

[0078] The limiting cutting device can move and can change the distance from the two limiting curved frames 301. When the rear end of the plate to be processed can contact the limiting cutting device, the plate to be processed can also be cut, so as to realize changing the length of the zipper teeth and processing zipper teeth of the required length.

[0079] The described limiting cutting device includes a curved fixed connection plate 401, a sliding column group 402, a telescopic lead screw 403, an internal thread cavity 404, an adjusting plate 501, a limiting groove 502, a cutting edge 503, and a linkage plate 504. The curved fixed connection plate 401 is fixedly connected to the fixed plate 101 by welding. Two sliding column groups 402 are fixedly connected to the curved fixed connection plate 401 by welding. The telescopic lead screw 403 is rotatably connected to the curved fixed connection plate 401 through a bearing seat. The internal thread cavity 404 is threadedly connected to the telescopic lead screw 403. The adjusting plate 501 is fixedly connected to the internal thread cavity 404 by welding. The adjusting plate 501 is fixedly connected to the two sliding column groups 402 by welding. The adjusting plate 501 is provided with a limiting groove 502. The outer end of the limiting groove 502 is provided with a cutting edge 503. The linkage plate 504 is fixedly connected to the adjusting plate 501 by welding. The linkage plate 504 is fixedly connected to the sliding connection plate 601 by welding.

[0080] The curved fixed connection plate 401 plays a role of bearing and connection. The sliding column group 402 is composed of a sliding column and a sliding cavity, which realizes the limitation of the adjusting plate 501, enabling the adjusting plate 501 to only slide back and forth. The rotating telescopic lead screw 403 can drive the internal thread cavity 404 to move, so that the internal thread cavity 404 can drive the adjusting plate 501 to slide back and forth. Due to the different positions of the adjusting plate 501, the distances from the two limiting curved frames 301 are different, resulting in different lengths of the processed zipper teeth. According to the requirements, the position of the adjusting plate 501 is changed. The limiting groove 502 can provide a sliding space for the processed plate and limit it to prevent the plate from moving erratically during the movement. The cutting edge 503 can be used to process the plate to process a plate with the required width, ultimately changing the length of the processed zipper teeth. The adjusting plate 501 can drive the linkage plate 504 to move, and the linkage plate 504 can drive the sliding connection plate 601 to slide, ultimately changing the positions of the rotating shaft 603 and the rotating wheel 604 to ensure that the rotating shaft 603 and the rotating wheel 604 are in the correct positions, realizing the processing of the installation groove at the rear end of the plate.

[0081] According to the instructions attached Figure 7 and 8 As described in detail, the chain tooth processing device further includes a sliding connection plate 601, a limiting sliding column 602, a rotating shaft 603, and a rotating wheel 604. Four limiting sliding columns 602 are slidably connected to the sliding connection plate 601. All four limiting sliding columns 602 are fixedly connected to the contact frame 102 by welding. The rotating shaft 603 is rotatably connected to the sliding connection plate 601 through a bearing. The rotating wheel 604 is fixedly connected to the rotating shaft 603 by welding. The sliding connection plate 601 is fixedly connected to the limiting cutting device by welding.

[0082] The limit cutting device can drive the sliding plate 601 to move. According to the width of the plate to be processed, the position of the sliding plate 601 will also change. The four limit sliding columns 602 can provide a sliding space for the sliding plate 601 and limit it, so that the sliding plate 601 can only slide in the front and back directions. A reduction motor III is fixedly connected to the sliding plate 601, and the reduction motor III is fixedly connected to the rotating shaft 603. A plurality of processing teeth are provided on both the rotating shaft 603 and the rotating wheel 604. The rear end of the plate is processed by using two groups of a plurality of processing teeth. Before the processed plate contacts the rotating shaft 603 and the rotating wheel 604, start the reduction motor III on the sliding plate 601 to drive the rotating shaft 603 to rotate, and the rotating rotating shaft 603 can drive the rotating wheel 604 to rotate. At this time, when the processed plate contacts the rotating rotating shaft 603 and the rotating wheel 604, cutting treatment can be carried out at the rear end of the processed plate, and the groove is processed behind the processed plate. When there is a groove at the rear of the processed plate, it can provide a sliding space for the cloth strip and can also undergo a certain deformation to ensure that a plurality of processed zipper teeth are installed on the cloth strip.

[0083] According to the attached drawings of the specification Figure 1 、 2 and 9 for detailed description, the chain tooth processing device further includes two rotating seat plates 701 and two transmission wheels II 702. The two rotating seat plates 701 are respectively fixedly connected to both sides above the contact frame 102 by welding. Transmission wheels II 702 are rotatably connected to the two rotating seat plates 701 through shafts, and the two transmission wheels II 702 are respectively located in two notches above the limit frame 103.

[0084] Grooves are provided on both of the two transmission wheels II 702, and reduction motors IV are fixedly connected to both of the two rotating seat plates 701. The output shafts of the two reduction motors IV are respectively fixedly connected to the two transmission wheels II 702. When the processed plate is located between the contact frame 102 and the limit frame 103, at this time, a groove needs to be processed on the plate. At this time, the plate needs to keep moving forward to complete the processing of the groove on the plate. Start the reduction motors IV on the two rotating seat plates 701 to drive the two transmission wheels II 702 to rotate, and the two rotating transmission wheels II 702 will contact the processed plate and drive it to move, ensuring that the processed plate keeps moving forward to complete the processing of the groove on the whole plate, so that the processed zipper teeth can be more easily installed on the cloth strip.

[0085] According to the attached drawings of the specification Figure 1 、 2As described in detail in FIGS. 10, the chain tooth processing device further includes an extended fixed plate 801, a limit sliding frame 802, a telescopic rod 803, and a cutting knife 804. The extended fixed plate 801 is fixedly connected to the contact frame 102 by welding. The limit sliding frame 802 and the telescopic rod 803 are fixedly connected to the extended fixed plate 801 by welding. The telescopic rod 803 is fixedly connected to the cutting knife 804 by welding. The cutting knife 804 is slidably connected within the limit sliding frame 802.

[0086] The extended fixed plate 801 serves a role of bearing and fixing, providing a fixed space for the limit sliding frame 802 and the telescopic rod 803. The limit sliding frame 802 can provide a sliding space for the cutting knife 804 and limit the cutting knife 804, enabling the cutting knife 804 to only slide left and right. The telescopic rod 803 can drive the cutting knife 804 to move. The cutting knife 804 can perform cutting processing on the processed zipper teeth. When the processed plate is discharged between the contact frame 102 and the limit frame 103, the telescopic rod 803 is activated to drive the cutting knife 804 to slide left and right repeatedly. The left and right sliding cutting knife 804 can perform cutting processing on the processed plate, ensuring that individual zipper teeth are processed and eliminating the need for subsequent reprocessing of the zipper teeth.

[0087] The chain tooth processing device further includes a discharge port 104, a storage basin 901, and an inclined sliding plate 902. The discharge port 104 is provided on the fixed plate 101. The storage basin 901 is fixedly connected to the upper part of the right end of the fixed plate 101 by welding. The inclined sliding plate 902 is fixedly connected to the upper part of the left end of the fixed plate 101 by welding. The inclined sliding plate 902 is located below the pressing wheel 202.

[0088] The discharge port 104 can provide a sliding space for the cut plate. When the plate is cut by the cutting edge 503, a part of the plate will be cut off, and the cut plate will be discharged through the discharge port 104. The storage basin 901 can provide a storage space for the cut zipper teeth, achieving the unified collection of zipper teeth. When the plate is pressed and processed using multiple processing grooves 203, the plate will be cut into pieces, and each piece of the plate will be located within the multiple processing grooves 203 respectively. At this time, when the pressing wheel 202 rotates, the small pieces of the plate located in the multiple processing grooves 203 will fall, directly onto the inclined sliding plate 902, and slide down. At this time, the small pieces of the plate will be directly discharged outside the device without affecting the operation of the device.
