[0048] See also Figures 1 to 4 The present application provides an inner pressure frame device for a pocket sticking machine, comprising:

[0049] A base 100, on which a motor 101 is disposed;

[0050] The limiting plate 200 is fixed to the base 100, and a plurality of guide grooves 201 are formed on the limiting plate 200;

[0051] The pressure plate assembly 400 includes a plurality of pressure plates that are slidably matched with the limiting plate 200;

[0052] The telescopic plate 300 is slidably stacked on the limiting plate 200, and the telescopic plate 300 is connected to the pressing plate assembly 400 to drive each pressing plate to move along the corresponding guide groove 201;

[0053] The gear rack mechanism 500 is transmission-connected between the telescopic plate 300 and the motor 101 to drive the telescopic plate 300 to slide back and forth along the first direction.

[0054] The rack and pinion mechanism 500 can realize fast and precise adjustment of the telescopic plate 300 under the drive of the motor 101, especially the precise adjustment of multiple stop positions, so that the internal pressure frame device can be quickly adjusted for fabrics of different sizes; at the same time, the rack and pinion can realize transmission reversing, realize the horizontal placement of the motor, and optimize the spatial layout.

[0055] In one embodiment, the rack and pinion mechanism 500 includes:

[0056] Gear 501, transmission connected to the main shaft of motor 101;

[0057] The rack 502 is fixed to the telescopic plate 300 and meshes with the gear 501 .

[0058] It can be understood that the rack 502 extends in the first direction to achieve stable meshing during the driving process. The first direction in this embodiment can be the extension direction of the rack or the extension direction of the front guide groove or the rear guide groove described below. In the embodiment shown in the accompanying drawings, the above two directions are parallel. Further, there are relative front and rear sides in the first direction; the pressure plate assembly 400 is located on the front side of the limit plate 200, and the rack 502 is located on the rear side of the limit plate 200. This setting can achieve that the gear 501 and the rack 502 are relatively far away from the pressure plate assembly 400, avoiding interference with the working process of the pressure plate assembly 400 due to the transmission setting. It should be noted that the "located" here only represents the spatial position relationship and does not limit the connection and transmission relationship of the components. Furthermore, a cushion seat 503 is fixed to the rear side of the telescopic plate 300, the rack 502 is fixed to the cushion seat 503 with the tooth surface facing upward, and the gear 501 is above the rack 502. The telescopic plate 300, the raised seat 503 and the rack 502 can be set as a split structure as shown in the figure and installed by fasteners. The raised seat 503 can adjust the assembly relationship between the components, eliminate manufacturing errors, and facilitate debugging and installation. For example, the raised seat 503 can realize the flexible setting of the position of the motor 101, thereby providing installation space for other components, such as the locking cylinder 103 described below.

[0059] In addition to the transmission function, the rack and pinion mechanism 500 can also realize other functions:

[0060] For example, the gear rack mechanism 500 can realize the limiting function, and the movement stroke of the telescopic plate 300 can be realized by adjusting the meshing distance of the rack 502. In the figure, the stroke of the telescopic plate 300 is limited by the cooperation with the limiting plate 200, so the rear side of the rack 502 in the figure is open and has an open space. In the free state, the rack 502 can move to the front side to disengage from the gear 501 for easy assembly. The free state refers to the state where the limiting plate 200 is not locked by the locking cylinder 103, and see the corresponding section below for details.

[0061] For another example, the gear rack mechanism 500 can realize the transmission reversing function. In the figure, the motor 101 is located at the rear side of the limit plate 200. The main shaft of the motor 101 is arranged along the second direction and is directly connected to the gear 501. The second direction is arranged to intersect with the first direction. In the figure, the second direction is perpendicular to the first direction. The motor of this arrangement can provide a layout as compact as possible while ensuring the driving power, avoiding the influence of the transmission structure and the motor arrangement on the overall size of the inner pressure frame device.

[0062] For another example, the rack and pinion mechanism 500 can achieve a change in transmission ratio.

[0063] As can be seen from the above, the inner pressure frame device is driven by the motor 101 and the gear 501 and the rack 502, and the position movement of the pressure plate of the inner pressure frame device is achieved by the mutual cooperation of the limit plate 200 and the telescopic plate 300. Figure 5 To Attachment Figure 7 Further explanation.

[0064] For the specific configuration of the limit plate 200, see Figure 6 , a guide groove 201 is provided on the limit plate 200, and the guide groove 201 includes a front guide groove 202 extending along a first direction, and two groups of side guide grooves 203 arranged obliquely to the first direction. The side guide groove 203 has a bending portion 2031 and is divided into two working sections by the bending portion 2031. The two working sections can realize speed segmentation regulation. The two groups of side guide grooves 203 are respectively a left guide groove group 2034 and a right guide groove group 2035, and the guide grooves in the same group are at least two arranged side by side. The guide grooves in the same group are arranged in parallel. The left guide groove group 2034 and the right guide groove group 2035 are symmetrically arranged on both sides of the extension direction of the front guide groove 202. The left guide groove and the right guide groove in relative positions have opposite ends adjacent to each other, and the front guide groove 202 avoids the opposite ends in the first direction. The rear sides of the left guide groove and the right guide groove in relative positions are opposite ends adjacent to each other, and the front sides of the two are opposite ends away from each other.

[0065] In one embodiment, the two working sections include:

[0066] The first section 2032 is adjacent to the opposite end, and the included angle between the extension direction of the first section 2032 and the first direction is α1;

[0067] The second section 2033 is adjacent to the opposite end, and the included angle between the extension direction of the second section 2033 and the first direction is α2;

[0068] And it satisfies that α1 is less than α2.

[0069] Furthermore, α1 is 1.5 to 3 times greater than α2. In the figure, α1 is 15 to 30 degrees, and α2 is 45 to 60 degrees.

[0070] Independent of the above, the limit plate 200 may also be provided with a rear guide groove 205, which extends along the first direction and is located at one end of the limit plate 200 away from the front guide groove 202. The rear guide groove 205 provides guidance for the mutual movement between the limit plate 200 and the telescopic plate 300. For example, in the figure, a portion of the bottom of the pad 503 interconnected with the rack 502 enters the rear guide groove 205, and the movement in the first direction is achieved under the constraint of the rear guide groove 205. In the figure, the limit plate 200 is connected to the die change seat 102, and the die change seat 102 is plugged into the base 100. The base 100 is provided with a locking mechanism for keeping the die change seat in a combined state, such as the locking cylinder 103 shown in the figure. The limit plate 200 and the telescopic plate 300 and the pressure plate assembly 400 arranged on the connection with the limit plate 200 can be quickly and stably installed on the base 100 or removed from the base 100 through the die change seat 102.

[0071] For the specific configuration of the telescopic plate 300, see Figure 7 , two groups of drive grooves 301 are provided on the telescopic plate 300, and each drive groove 301 overlaps and obliquely intersects with the corresponding side guide groove 203. The two groups of drive grooves 301 are respectively a left drive groove group 3011 and a right drive groove group 3012, and the same group of drive grooves is at least two arranged side by side. The same group of drive grooves are arranged in parallel. The left drive groove group 3011 and the right drive groove group 3012 are symmetrically arranged on both sides of the extension direction of the front guide groove 202. The left drive groove and the right drive groove, which are relatively positioned, gradually move away from the front side to the rear side, and the angle with the first direction is α3. A trigger block 302 is also provided on the telescopic plate 300, and a sensor (not shown) triggered by the trigger block 302 is fixed on the base 100, and the motor 101 responds to the signal of the sensor to realize the electric drive control independent of the mechanical limit.

[0072] For the specific configuration of the pressure plate assembly 400, see Figure 3 as well as Figure 5The pressure plate assembly 400 includes a front pressure plate 401 that moves along the front guide groove 202, and a left pressure plate 402 and a right pressure plate 403 that move along the side guide grooves 203. The left pressure plate 402 and the right pressure plate 403 are arranged on both sides of the front pressure plate 401; the left pressure plate 402 and the right pressure plate 403 are respectively fixed with first guide pins 404, and each first guide pin 404 passes through the corresponding guide groove and driving groove. When there are multiple guide grooves and driving grooves, there are also multiple first guide pins 404, and one pressure plate corresponds to at least two first guide pins 404 to ensure the movement direction of the left pressure plate 402 and / or the right pressure plate 403. Different first guide pins 404 are located in different guide grooves and driving grooves. Similarly, the front pressure plate 401 is fixed with a second guide pin 405, and the second guide pin 405 passes through the front guide groove 202 and is fixed to the telescopic plate 300. There are multiple second guide pins 405 to ensure the movement direction of the front pressure plate 401. The plurality of second guide pins 405 are located in the same guide slot and driving slot. The left pressing plate 402 and the right pressing plate 403 have a front edge 4091 and a side edge 4092 respectively, wherein the angle between the front edge 4091 and the first direction is equal to α3.

[0073] For details on the coordination of the three, see Figure 5 , the telescopic plate 300 is slidably stacked on the upper side of the limiting plate 200, and the left pressing plate 402 and the right pressing plate 403 are slidably stacked on the lower side of the limiting plate 200 through the corresponding connecting plates 406. In the figure, the front pressing plate 401 is also provided with a connecting plate 406.

[0074] Two washers are sleeved on the first guide pin 404, one of which is located between the telescopic plate 300 and the limiting plate 200, and the other is located between the limiting plate 200 and the corresponding connecting plate 406. The first washer 407 is located between the telescopic plate 300 and the limiting plate 200, and the second washer 408 is located between the limiting plate 200 and the corresponding connecting plate 406. A plurality of first washers 407 form a first gap between the telescopic plate 300 and the limiting plate 200, and a plurality of second washers 408 form a second gap between the limiting plate 200 and the corresponding connecting plate 406. The first gap and the second gap can reduce the contact area, thereby reducing the movement resistance between the telescopic plate 300 and the limiting plate 200, and between the limiting plate 200 and the corresponding connecting plate 406. Further, the first washer 407 and the second washer 408 can be made of self-lubricating material, such as oil-containing nylon. Under high working intensity conditions, the first washer 407 and the second washer 408 can also be made of metal, and the contact surface can be smoothed. Similarly, a friction reduction structure can also be set between the guide pin, the drive groove and the guide groove, such as the guide ring 204 shown in the figure. In the figure, the guide ring 204 is set in the guide groove, and the guide ring 204 is sleeved on the guide pin and abuts against the side wall of the guide groove. The guide ring 204 can also be set in the rear guide groove 205.

[0075] In the specific driving process, there are relative front and rear sides in the first direction; when the front pressing plate 401 moves to the front side, the left pressing plate 402 and the right pressing plate 403 move away from each other in the second direction while moving to the front side. When the front pressing plate 401 moves to the rear side, the left pressing plate 402 and the right pressing plate 403 move toward the rear side while moving toward each other in the second direction.

[0076] Based on the above, the present application provides a pocket sticking machine in one embodiment, including the inner pressure frame device for the pocket sticking machine in the above technical solution. Other parts of the pocket sticking machine structure can be implemented in combination with the existing technology.

[0077] The technical features of the above-mentioned embodiments can be combined arbitrarily.
