[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0030] In the description of the present invention, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0031] In the description of the present invention, it should be understood that when an element is considered to be "connected" to another element, it may be directly connected to the other element or there may be intermediate elements at the same time. On the contrary, when an element is said to be "directly" connected to another element, there are no intermediate elements.

[0032] In one embodiment, see Figure 1 and Figure 2 A mold changing assembly 10 includes: a fixed seat 11, a sewing pressure plate 12 and a sensing mechanism 13. The fixed seat 11 is provided with an opening area 111. The sewing pressure plate 12 is mounted on the fixed seat 11, and is provided with a sewing opening 121 adapted to the sewing pattern. The sewing opening 121 is arranged corresponding to the opening area 111. The sensing mechanism 13 is used to be electrically connected to a control host (not shown in the figure), and the sensing mechanism 13 is used to send a signal of the sewing pattern corresponding to the sewing pressure plate 12 to the control host.

[0033] The above-mentioned mold changing assembly 10, after replacing a different sewing pressure plate 12, the sensing mechanism 13 sends the signal of the sewing pattern corresponding to the sewing pressure plate 12 to the control host. When working, the control host can control the sewing mechanism accordingly to perform sewing work according to the signal provided by the sensing mechanism 13, so that it can adapt to the production of cutting pieces with sewing patterns of different shapes, and at the same time the work efficiency is relatively high.

[0034] For further information, see Figures 1 to 3The sensing mechanism 13 includes a sensor (not shown in the figure), a sensing seat 131 and a sensing sheet 132. The sensing seat 131 is disposed on the fixing seat 11, and the sensing sheet 132 is adjustable in position on the sensing seat 131. The sensor is used to obtain the position information of the sensing sheet 132 on the sensing seat 131 and send the position information to the control host, and the sensor is used to be electrically connected to the control host.

[0035] In this way, different positions of the sensing piece 132 on the sensing seat 131 correspond to different sewing patterns of the sewing pressing plate 12. After the control host receives the position information of the sensing piece 132 on the sensing seat 131, it can obtain the sewing pattern of the sewing pressing plate 12 according to the position information. That is, after replacing the sewing pressing plate 12, the position of the sensing piece 132 on the sensing seat 131 is adjusted so that the position information corresponds to the sewing pattern of the sewing pressing plate 12. In this way, when the machine is turned on, the sewing pattern information of the sewing pressing plate 12 can be obtained relatively quickly without using a barcode, and the work efficiency is greatly improved.

[0036] For further information, see Figures 1 to 3 , the surface of the sensing seat 131 is provided with a plurality of grooves 1311 adapted to the sensing sheet 132. Thus, when the sensing sheet 132 is placed in one of the grooves 1311, it corresponds to one sewing pattern of the sewing press plate 12, and when the sensing sheet 132 is placed in different grooves 1311, it corresponds to different sewing patterns. In addition, when the sensing sheet 132 is arranged in the grooves 1311, it can be arranged on the sensing seat 131 more stably.

[0037] Optionally, the induction sheet 132 is magnetically matched with the induction seat 131. Specifically, the induction sheet 132 is stainless steel, and the induction seat 131 is a magnet. Alternatively, the induction sheet 132 is a magnet, and the induction seat 131 is stainless steel. In this way, by adopting the magnetic matching method, the position of the induction sheet 132 on the induction seat 131 can be easily adjusted.

[0038] In one embodiment, see Figures 1 to 3, the number of the grooves 1311 is nine and arranged in a nine-square grid, and the number of the sensing pieces 132 is one, two or three. That is, when there is one sensing piece 132, the sensing piece 132 can be placed in any one of the nine grooves 1311, that is, it corresponds to at most nine sewing patterns of the sewing pressing plate 12, and at most nine pockets with sewing patterns can be made; when there are two sensing pieces 132, the sensing piece 132 can be placed in any two of the nine grooves 1311, that is, it corresponds to at most 36 sewing patterns of the sewing pressing plate 12, and at most 36 pockets with sewing patterns can be made; when there are three sensing pieces 132, the sensing piece 132 can be placed in any three of the nine grooves 1311, that is, it corresponds to at most 84 sewing patterns of the sewing pressing plate 12, and at most 84 pockets with sewing patterns can be made.

[0039] Of course, the number of the induction plates 132 may also be other numbers, such as four, five, etc.

[0040] In one embodiment, see Figures 1 to 3 , the bottom wall of the groove 1311 is correspondingly provided with a digital number mark. It is understandable that the digital number mark can be, for example, a lowercase number or an uppercase number. Generally, the sewing patterns of different sewing pressing plates 12 have corresponding digital codes. In this way, the sensor sheet 132 is placed in the groove 1311 on the sensor seat 131 according to the digital code corresponding to the sewing pressing plate 12 and the digital number mark on the bottom wall of the groove 1311, so that it can be operated quickly and accurately, which is conducive to improving work efficiency. Specifically, when there are nine grooves 1311, the bottom walls of the nine grooves 1311 correspond to numbers 1 to 9 respectively.

[0041] In one embodiment, see Figures 1 to 3 The sensing seat 131 is detachably stacked on the fixing seat 11, and the groove 1311 is provided on the surface of the sensing seat 131 facing away from the fixing seat 11. In this way, on the one hand, space can be saved, and on the other hand, the position of the sensing sheet 132 on the groove 1311 can be easily adjusted, and the operation is convenient.

[0042] For more details, please refer to Figure 3 The sensing seat 131 is provided with a lug 1312, the lug 1312 is provided with a screw hole, the fixing seat 11 is provided with a fixing hole corresponding to the screw hole, and the sensing seat 131 is fixed to the fixing seat 11 by screws or bolts passing through the screw holes and the fixing holes. Of course, as an optional solution, the sensing seat 131 can also be fixed to the fixing seat 11 by means of, for example, clamping, bonding, etc.

[0043] In another embodiment, the sensing mechanism 13 is an electronic input device. The electronic input device is used to be electrically connected to the control host, and the electronic input device is used to record the coding information of the sewing pattern of the sewing pressing plate 12 and send the coding information to the control host.

[0044] Specifically, the electronic input device is, for example, a touch screen or a keypad, which directly records the coding information of the sewing pattern of the sewing pressing plate 12 and sends the coding information to the control host during operation.

[0045] In one embodiment, see Figures 1 to 3 The die changing assembly 10 further includes a mounting plate 14. The fixing seat 11 is detachably mounted on the mounting plate 14, and the mounting plate 14 is provided with an escape area 141 for escaping the sewing mechanism. The escape area 141 is arranged opposite to the opening area 111, and the mounting plate 14 is used to be mounted on the sewing bracket.

[0046] For further information, see Figures 1 to 3 , the mounting plate 14 is provided with an axle pin 15, and the fixing seat 11 is provided with a clamping sleeve 16 matched with the axle pin 15 and a clamping shaft 17 mounted on the clamping sleeve 16. The clamping sleeve 16 is sleeved on the axle pin 15, and the clamping shaft 17 is used to fix the axle pin 15 on the clamping sleeve 16. In this way, the fixing seat 11 can be easily and quickly mounted on the mounting plate 14.

[0047] Furthermore, there are two shaft pins 15 and two clamping sleeves 16. The two shaft pins 15 are respectively arranged on both sides of the mounting plate 14, and the two clamping sleeves 16 are respectively arranged on both sides of the fixing seat 11, and the two clamping sleeves 16 are arranged one by one with the two shaft pins 15.

[0048] Specifically, see Figure 5 and Figure 6 , a limiting opening 151 is provided on the side wall of the shaft pin 15, and the limiting opening 151 can be specifically arranged around the circumference of the shaft pin 15. A sleeve 18 is provided on the side wall of the ferrule 16, and the sleeve 18 passes through the side wall of the ferrule 16 and communicates with the sleeve hole 161 of the ferrule 16. The clamping shaft 17 is movably arranged in the tube hole 181 of the sleeve 18, and the clamping shaft 17 is connected to the tube wall of the sleeve 18 through the elastic member 19. When the elastic member 19 is in a normal state, the clamping shaft 17 is driven to extend into the sleeve hole 161 of the ferrule 16 and to limit the position with the limiting opening 151; when the elastic member 19 is in a compressed state, the clamping shaft 17 moves out of the limiting opening 151, that is, the pin shaft is no longer limited, and the pin shaft can be separated from the ferrule 16.

[0049] For further information, see Figure 5 and Figure 6, the elastic member 19 is a spring, and the spring is sleeved on the clamping shaft 17. More specifically, the tube hole 181 includes a first through hole 1811 and a second through hole 1812 that are connected. The diameter of the first through hole 1811 is larger than the diameter of the second through hole 1812, that is, the tube hole 181 is a stepped hole. The head end of the clamping shaft 17 is provided with a flange that contacts one end of the spring, and the other end of the spring contacts the stepped surface of the stepped hole.

[0050] For further information, see Figure 5 and Figure 6 A notch 182 is provided on the side wall of the end of the sleeve 18 away from the ferrule 16, and the clamping shaft 17 includes a first shaft section 171 and a second shaft section 172. The first shaft section 171 is connected to the second shaft section 172, so that the clamping shaft 17 is L-shaped. The first shaft section 171 is installed in the tube hole 181 of the sleeve 18, and is used to limit the position of the limit opening 151 of the pin shaft. The second shaft section 172 is located outside the sleeve 18, and is used to conflict with the tube wall of the sleeve 18. The second shaft section 172 can move along the notch 182. In this way, when the end of the first shaft segment 171 is inserted into the limiting opening 151 of the shaft pin 15, the shaft pin can be fixedly installed in the sleeve 16, and the second shaft segment 172 is located in the notch 182 at this time; when the shaft pin needs to be separated from the sleeve 16, the clamping shaft 17 is moved along the axial direction, and the spring is compressed when the clamping shaft 17 is moved. After the second shaft segment 172 is moved out of the notch 182, the clamping shaft 17 is rotated so that the second shaft segment 172 is fixed in contact with the end face of the sleeve 18. At this time, the clamping shaft 17 is separated from the limiting opening 151 and no longer limits the shaft pin, so the shaft pin can be separated from the sleeve 16.

[0051] In addition, the fixing seat 11 can also be detachably mounted on the mounting plate 14 in other ways.

[0052] In one embodiment, see Figures 1 to 3 A mold changing method of the mold changing assembly 10 described in any of the above embodiments comprises the following steps:

[0053] Step S10, before starting the machine, install the sewing pressing plate 12 on the fixing seat 11;

[0054] Step S20, adjusting the sensing mechanism 13 according to the sewing pattern of the sewing pressing plate 12;

[0055] Step S30, after the machine is turned on, the sensing mechanism 13 sends the signal of the sewing pattern corresponding to the sewing pressing plate 12 to the control host.

[0056] In the mold changing method of the above-mentioned mold changing assembly 10, after replacing a different sewing pressure plate 12, the sensing mechanism 13 sends the signal of the sewing pattern corresponding to the sewing pressure plate 12 to the control host. When working, the control host can control the sewing mechanism to perform sewing work according to the signal provided by the sensing mechanism 13. In this way, it can adapt to the production of cutting pieces with sewing patterns of different shapes, and the work efficiency is relatively high.

[0057] For further information, see Figures 1 to 3 , wherein the sensing mechanism 13 includes a sensor, a sensing seat 131 and a sensing sheet 132. The sensing seat 131 is disposed on the fixing seat 11, and the sensing sheet 132 is adjustable in position on the sensing seat 131. The sensor is used to obtain the position information of the sensing sheet 132 on the sensing seat 131 and send the position information to the control host, and the sensor is used to be electrically connected to the control host.

[0058] The above-mentioned step S20 specifically includes: adjusting the position of the sensing sheet 132 on the sensing seat 131 so that the position information corresponds to the sewing pattern of the sewing pressing plate 12 .

[0059] In this way, when the machine is turned on, the information of the sewing pattern of the sewing pressing plate 12 can be obtained relatively quickly without using a bar code, thereby greatly improving the working efficiency.

[0060] Further, see Figures 1 to 3 There are nine grooves 1311 arranged in a nine-square grid, there are two sensing sheets 132, for example, and numbers 1 to 9 are respectively written on the bottom walls of the grooves 1311.

[0061] The above steps make the position information correspond to the sewing pattern of the sewing pressing plate 12 , specifically: the code of the sewing pattern of the sewing pressing plate 12 is made to correspond to the number on the bottom wall of the groove 1311 on the sensor seat 131 .

[0062] In this way, according to the code of the sewing pattern of the sewing pressing plate 12, the sensor plate 132 can be quickly placed in the groove 1311 of the corresponding number, which is convenient for operation and has high work efficiency.

[0063] For example, when the sewing pattern of the sewing pressure plate 12 is coded as 56, the two sensor plates 132 are respectively placed in the two grooves 1311 with numbers 5 and 6 on the bottom wall. At this time, the positions of the two sensor plates 132 correspond to the sewing pressure plate 12 coded as 56; for another example, when the sewing pattern of the sewing pressure plate 12 is coded as 23, the two sensor plates 132 are respectively placed in the two grooves 1311 with numbers 2 and 3 on the bottom wall. At this time, the positions of the two sensor plates 132 correspond to the sewing pressure plate 12 coded as 23.

[0064] In one embodiment, see Figures 1 to 3 A sewing system includes the die changing assembly 10 described in any of the above embodiments, and also includes a control host and a sewing mechanism. The control host is electrically connected to the sensing mechanism 13 and the sewing mechanism respectively, and the control host is used to obtain a signal of a sewing pattern corresponding to the sewing pressing plate 12, and the control host is also used to control the action of the sewing mechanism according to the sewing pattern.

[0065] In the above-mentioned sewing system, after replacing different sewing pressure plates 12, the sensing mechanism 13 sends the signal of the sewing pattern corresponding to the sewing pressure plate 12 to the control host. When working, the control host can control the sewing mechanism to perform sewing work according to the signal provided by the sensing mechanism 13. In this way, it can adapt to the production of cutting pieces with sewing patterns of different shapes, and the working efficiency is relatively high.

[0066] For further information, see Figures 1 to 3 The sewing system further comprises a sewing bracket. The sewing bracket is provided with a working panel. A sewing pressing plate 12 is arranged above the working panel. A mounting plate 14 is detachably arranged on the sewing bracket.

[0067] Furthermore, there are more than two mold changing components 10, and more than two sewing mechanisms. The two or more sewing mechanisms are arranged one by one with the two or more mold changing components 10. The control host is electrically connected to the two or more sensing mechanisms 13 and the two or more sewing mechanisms respectively. In this way, the two or more sewing mechanisms can be operated.

[0068] For further information, see Figure 4 The control host is also electrically connected to a display screen 20. The display screen 20 is used to display the sewing pattern and digital code of the sewing pressing plate 12. In this way, when the sewing mechanism is working, the sewing pattern and digital code of the sewing pressing plate 12 can be directly compared with the sewing pattern and digital code displayed on the display screen 20, thereby ensuring the product qualification rate.

[0069] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0070] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
