In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application 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 application, so the present application is not limited by the specific embodiments disclosed below.

[0052] It should be noted that when a component is referred to as being "fixed to" or "disposed on" another component, it may be directly on the other component or there may also be a central component. When a component is considered to be "connected to" another component, it may be directly connected to the other component or there may be a central component at the same time. The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in the specification of this application are for illustrative purposes only and do not represent the only implementation method.

[0053] In addition, 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 the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of this application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0054] In the present application, unless otherwise clearly specified and limited, a first feature being “above” or “below” a second feature may mean that the first feature is directly in contact with the second feature, or the first feature and the second feature are indirectly in contact through an intermediate medium. Moreover, a first feature being “above”, “above”, or “above” a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level (or in a state of use, or from a certain perspective of the drawing) than the second feature. A first feature being “below”, “below”, or “below” a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level (or in a state of use, or from a certain perspective of the drawing) than the second feature.

The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used in the specification of this application includes any and all combinations of one or more related listed items.

[0056] See also Figures 1 to 5 In one embodiment of the present application, a power device of a folding device of a pocket sticking machine is provided, which is used to drive a bag-shaped plate (not shown) and a folding device (not shown) of the pocket sticking machine, and the power device includes:

[0057] The base 100 includes a bottom plate 101 and two side plates 102 fixed to the bottom plate 101 and arranged opposite to each other;

[0058] A first driving mechanism 200 is mounted on the base 100;

[0059] The lifting platform 300 is slidably installed between the two side plates 102. The lifting platform 300 is connected to the first driving mechanism 200 by a transmission method of a gear 203 and a rack 204. The lifting platform 300 is a box-shaped frame structure as a whole, and the top surface of the frame structure is used to install the folding device;

[0060] The buffer mechanism 400 is connected between the base 100 and the lifting platform 300 .

[0061] The base 100 and the lifting platform 300 slide together to define the lifting movement direction. The first driving mechanism 200 only needs to provide drive without providing constraints. Combined with the buffer mechanism 400, the load of the first driving mechanism 200 is further reduced, and a compact overall layout can be achieved while stably driving the folding device.

[0062] See also Figure 1 , Figure 3A guiding mechanism cooperating with each other is provided between the opposite sides of the two side panels 102 and the lifting platform 300. Further, the guiding mechanism includes:

[0063] A plurality of pairs of guide rails 301, wherein the same pair of guide rails 301 are arranged on opposite sides of the lifting platform 300;

[0064] The linear bearings 103 are fixed to the opposite sides of the two side panels 102, and the linear bearings 103 are respectively slidably matched with the corresponding guide rails 301. In the figure, two linear bearings 103 are sequentially provided in the direction of the guide rails 301 and both are matched with the guide rails 301. In the figure, there are four guide rails 301 in total and they are arranged in parallel on the outer peripheral surface of the lifting platform 300, especially near the prism of the box-shaped frame structure. It can be understood that the guide rails 301 and the linear bearings 103 can be interchanged, that is, the linear bearings 103 are arranged on the lifting platform 300, and the guide rails 301 are arranged on the side panels 102.

[0065] In one embodiment, the buffer mechanism 400 is a gas spring. Figure 3 The base 100 is fixed with a connecting seat 104, the top of the lifting platform 300 is provided with a flange 302 extending outward, and the two ends of the gas spring are abutted between the connecting seat 104 and the flange 302. Figure 4 The flange 302 is provided with an adapter seat 303 on the side facing the connection, and the two ends of the gas spring abut between the connection seat 104 and the adapter seat 303. This arrangement can improve the stability of the gas spring. Similarly, the buffer mechanism 400 can be arranged in groups and located on different sides of the lifting platform 300.

[0066] In one embodiment, the gas spring only provides a thrust to drive the base 100 and the lifting platform 300 away from each other, and the thrust is less than the gravity of the lifting platform 300 and the device connected thereto. When the base 100 and the lifting platform 300 are close to each other, the gravity of the lifting platform 300 and the device connected thereto can drive the gas spring to compress; when the base 100 and the lifting platform 300 are away from each other, the gas spring assists the first drive mechanism 200 to achieve action. This setting also has a variety of beneficial effects in actual use, such as disability protection. When the first drive mechanism 200 is accidentally disabled (such as the motor 201 is powered off), the gas spring has a holding function to prevent the mechanism from suddenly falling and hitting the operator; another example is upward protection. After the movement stroke of the lifting platform 300 exceeds the stroke of the gas spring, the load is significantly increased, and the first drive mechanism 200 can trigger an overload alarm based on the load change; another example is load reduction optimization. The gravity friction force of each mechanism and the elastic force of the gas spring balance the weight, and the elastic force offsets the gravity, reducing the load of the first drive mechanism 200. On the whole, the gas spring-type buffer mechanism can reduce structural complexity and improve economy while achieving various functions.

[0067] In one embodiment, the first driving mechanism 200 includes:

[0068] The motor 201 is mounted on one of the side panels 102;

[0069] The driving shaft 202 is rotatably mounted at both ends on the corresponding side plates 102 and is linked to the motor 201. The lifting platform 300 is provided with an escape opening 304 for the driving shaft 202 to pass through;

[0070] Gear 203, fixed to the driving shaft 202;

[0071] The rack 204 is fixed to the lifting platform 300 and meshes with the gear 203 for transmission.

[0072] In the figure, two racks 204 are arranged in parallel, and two gears 203 are arranged on the driving shaft 202 and mesh with the corresponding racks 204 respectively. The gears 203 are located on both sides of the driving shaft 202 and inside the lifting frame. The bottom of the rack 204 is against the top surface of the base frame 307 of the lifting platform 300, and the side adjacent to the tooth surface is fixed against the side frame 305 of the corresponding lifting platform 300. A gap is set between the top of the rack 204 and the crossbeam 308 of the lifting platform 300. Furthermore, the motor 201 is connected to one end of the driving shaft 202 through a synchronous belt 205 and a corresponding pulley. The number of teeth on the pulley is greater than the number of teeth on the motor 201 shaft of the motor 201.

[0073] In one embodiment, see Figure 4 , Figure 5 , the lifting platform 300 comprises:

[0074] The two side frames 305 are arranged opposite to each other and slidably cooperate with the corresponding side plates 102 in the base 100. There are two racks 204 and they are respectively fixed to the opposite sides of the two side frames 305. Two sets of gears 203 are correspondingly arranged.

[0075] A top frame 306, fixedly connected to the tops of the two side frames 305;

[0076] The bottom frame 307 is fixedly connected to the bottom of the two side frames 305;

[0077] The crossbeam 308 is fixedly connected between the two side frames 305 and is close to the top frame 306 in height.

[0078] In the figure, the bottom frame 307 and the cross beam 308 are provided with multiple pieces. A cross bar 309 is also provided between the side frames 305. The cross bars 309 are provided in parallel with multiple pieces and are all located between the bottom frame 307 and the top frame 306.

[0079] In one embodiment, see Figure 5The power device includes a second drive mechanism 500 and a coupling seat 502. The second drive mechanism 500 is installed inside the frame structure and has a translation drive member 501 extending out of the frame structure; the coupling seat 502 is installed on the translation drive member 501 and is used to install the bag-shaped plate. Further, the second drive mechanism 500 is installed on the crossbeam 308 and includes:

[0080] A fixing seat 503 is installed on the top surface of the lifting platform 300;

[0081] A driving cylinder 504 is mounted on a fixing seat 503;

[0082] A guide seat 505 is installed on the top surface of the lifting platform 300;

[0083] A guide shaft 506 is movably disposed on the guide seat 505;

[0084] In the figure, the fixed seat 503 is provided by the crossbeam 308 mentioned above, and the other crossbeam 308 avoids the driving cylinder 504. The guide seat 505 is installed on the crossbeam 308, and the two crossbeams 308 are provided with guide seats 505, and the guide shaft 506 passes through the two guide seats 505 in sequence. Two guide shafts 506 are provided in parallel and are respectively located on both sides of the driving cylinder 504. The two guide shafts 506 and the piston rods of the driving cylinder 504 are connected to the translation drive member 501 to realize the connection with the coupling seat 502. In this embodiment, the power device can achieve a compact overall layout while stably driving the bag-shaped plate and the folding device.

[0085] The following is an explanation of the working process in conjunction with specific components:

[0086] The power device is reset to zero before starting work. The reset operation is carried out according to the following specific steps:

[0087] The piston rod of the driving cylinder 504 of the second driving mechanism 500 is retracted back to a preset position, so that the position of the second driving mechanism 500 is reset to zero;

[0088] The motor 201 of the first driving mechanism 200 rotates and drives the driving shaft 202 to rotate through the synchronous belt 205, and the driving shaft 202 drives the gear 203 to rotate, and the gear 203 drives the rack 204 to move upward, and drives the lifting platform 300 as a whole upward. When it is detected that the lifting platform 300 moves upward to the position (corresponding to the upward position signal of the pocket fabric folding device in the sewing operation), the motor 201 stops rotating, and the position of the first driving mechanism 200 is reset to zero.

[0089] The working process of the power unit is implemented according to the following specific steps:

[0090] The piston rod of the driving cylinder 504 of the second driving mechanism 500 extends to a preset position to realize the translation driving member 501 and the bag-shaped plate installed on the translation driving member 501 extending to a preset position, and the bag-shaped plate cooperates with the folding device to complete the folding action of the pocket fabric;

[0091] The motor 201 of the first driving mechanism 200 rotates and drives the driving shaft 202 to rotate through the synchronous belt 205, and the driving shaft 202 drives the gear 203 to rotate, and the gear 203 drives the rack 204 to move downward, and drives the lifting platform 300 to move downward as a whole, so that the folded pocket fabric is attached to the body fabric;

[0092] The piston rod of the driving cylinder 504 of the second driving mechanism 500 is retracted to a preset position to realize the retraction of the translation driving member 501 and the bag-shaped plate installed on the translation driving member 501 to the preset position, and the bag-shaped plate is withdrawn from the folded pocket fabric;

[0093] The motor 201 of the first driving mechanism 200 rotates and drives the driving shaft 202 to rotate through the synchronous belt 205, and the driving shaft 202 drives the gear 203 to rotate, and the gear 203 drives the rack 204 to move upward, and drives the lifting platform 300 upward as a whole to facilitate the sewing device to take the material;

[0094] Repeat the above steps in sequence.

[0095] Based on the above, an embodiment of the present application further provides a pocket sticking machine with a power device of the pocket sticking machine folding device in the present application.
