DETAILED DESCRIPTION

[0035] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0036] like Figures 1 to 11 As shown, the embodiment of the present invention provides a forward and reverse gluing integrated machine, including a housing 101, a gluing mechanism 102 installed inside the housing 101, and a plurality of lower glue roller bodies 103 arranged inside the housing 101, including: a switching box 201 is fixedly connected inside the housing 101, and the lower glue roller body 103 is arranged inside the switching box 201, so as to isolate the unused lower glue roller body 103 from the working environment;

[0037] A switching plate 202 is symmetrically arranged inside the switching box 201, and a plurality of limiting flower rods 203 are arranged on the surface of the switching plate 202. By rotating the switching plate 202, part of the lower rubber roller body 103 is placed between the switching plates 202. By limiting the rotation of the corresponding limiting flower rods 203, the required lower rubber roller body 103 is lifted when the switching plate 202 is reset to a vertical state;

[0038] A plurality of positioning blocks 204 are fixedly connected to the surface of the switching plate 202, and grabbing columns 205 are fixedly connected to both ends of the lower rubber roller body 103, and a positioning and combining block 206 is fixedly connected to one end of the grabbing column 205 away from the lower rubber roller body 103. When the switching plate 202 is reset to the vertical state, the lifted lower rubber roller body 103 is clamped between the corresponding two positioning blocks 204 through the positioning and combining block 206;

[0039] A ratchet column 502 is disposed on the surface of the limiting flower rod 203, and a first sliding block 501 is disposed inside the switching plate 202. The rotation of the limiting flower rod 203 is limited by the cooperation between the first sliding block 501 and the ratchet column 502.

[0040] A multi-stage telescopic cylinder 208 is symmetrically arranged between the two switching plates 202. An adjusting block 212 is arranged on the surface of the multi-stage telescopic cylinder 208. The multi-stage telescopic cylinder 208 is used to transfer the lower rubber roller body 103 in the vertical direction. The adjusting block 212 is used to adjust the position relationship between the corresponding first sliding block 501 and the ratchet column 502, so that the rotation of the corresponding limiting flower rod 203 is constrained, so that the required lower rubber roller body 103 can be lifted in the process of resetting the switching plate 202 to the vertical state.

[0041] In this embodiment, a plurality of different lower rubber roller bodies 103 are equidistantly arranged on both sides of the switching plate 202, and the diameter of the positioning and binding blocks 206 on the surface of the lower rubber roller body 103 gradually increases from the switching plate 202 to both sides. When the switching plate 202 is in a vertical state, the distance between the two positioning blocks 204 at the same horizontal height on its surface gradually decreases from top to bottom, and the spacing between the positioning blocks 204 can clamp the positioning and binding blocks 206 of corresponding diameters. During the gluing process, when the lower rubber roller body 103 needs to be replaced, the two switching plates 202 are rotated 90 degrees clockwise or counterclockwise by controlling the operation of the first motor 211. At this time, all the grabbing columns 205 on the surface of the lower rubber roller body 103 enter the two switching plates 2 by rotating the limiting flower rod 203. 02, at this time, the multi-stage telescopic cylinder 208 is extended until the adjustment block 212 moves to make the corresponding first sliding block 501 squeeze against the ratchet column 502. At this time, the corresponding limiting flower rod 203 can only rotate in one direction and cannot rotate. Then the switching plate 202 is controlled to reset to a vertical state. At this time, a limiting flower rod 203 that can only rotate in one direction causes the corresponding lower glue roller body 103 to be lifted up following the reset of the switching plate 202, and under the action of gravity, it slides from the surface of one of the positioning blocks 204 to between the corresponding two positioning blocks 204, and is stuck by the two positioning blocks 204. When the switching plate 202 rotates to a vertical state, the multi-stage telescopic cylinder 208 is controlled to continue to extend, so that the lower glue roller body 103 is pushed out of the switching box 201 and enters the gluing operation area.

[0042] like Figure 7 As shown, the two switching plates 202 are rotatably connected to the switching box 201 through a convex bearing, the first motor 211 is symmetrically installed on the surface of the switching box 201, the ends of the output shafts of the two first motors 211 are fixedly connected to the switching plate 202, and two rows of limiting flower rods 203 are symmetrically arranged on the surface of the switching plate 202. The limiting flower rod 203 is rotatably connected to the switching plate 202 through a second bearing and a first circular groove opened on the surface of the switching plate 202. The surface of the switching plate 202 is symmetrically provided with two rows of positioning blocks 204, and the positioning blocks 204 are located between the switching plate 202 and the limiting flower rod 203.

[0043] In this embodiment, the two first motors 211 rotate synchronously, so that the switching plate 202 and the connecting plate 207 maintain consistent movement. When the switching plate 202 rotates 90 degrees from the vertical state, the positioning and coupling blocks 206 at the end of the lower rubber roller body 103 respectively enter between the two switching plates 202 from the gap between the two adjacent positioning blocks 204 in the corresponding column. In this process, the grabbing column 205 will cause the limiting flower rod 203 to rotate a certain angle. When the switching plate 202 is reset and rotated to the vertical state, the limiting flower rod 203 that is not restricted in rotation will rotate when passing through the corresponding grabbing column 205, so that the grabbing column 205 remains in place, and the limiting flower rod 203 that is restricted in unidirectional rotation will press against the corresponding grabbing column 205, so that the lower rubber roller body 103 between the two grabbing columns 205 is lifted.

[0044] like Figures 9 and 10 As shown, the first sliding block 501 is slidably connected in a rectangular cavity opened inside the switching plate 202, and one end of the limiting flower rod 203 located inside the switching plate 202 is fixedly connected to the ratchet column 502, and a plurality of pawl blocks 503 are arranged inside the first sliding block 501, and the pawl block 503 is engaged in one of the tooth grooves on the surface of the ratchet column 502, and the pawl block 503 is slidably connected in a first sliding groove opened on the surface of the first sliding block 501, and a plurality of second springs 504 are equidistantly arranged on the surface of the pawl block 503, and the two ends of the second spring 504 are respectively fixedly connected to the first sliding block 501 and the pawl block 503.

[0045] In this embodiment, when the pawl blocks 503 on the surface of the first sliding block 501 are respectively inserted into the tooth grooves on the surface of the ratchet column 502, when the pawl blocks 503 rotate in one direction, the inclined surface of the pawl block 503 will continuously slide between the teeth of the ratchet column 502, and reciprocate in the first sliding groove opened on the surface of the first sliding block 501 through the action of the elastic potential energy of the third spring 507. When the ratchet column 502 tends to rotate in the opposite direction, the side of the pawl block 503 opposite to the inclined surface will press against the inner wall of the tooth groove of the ratchet column 502, thereby limiting the rotation of the ratchet column 502, that is, limiting the rotation of the limiting flower rod 203.

[0046] like Fig. 9As shown, a connecting plate 207 is fixedly connected between the two switching plates 202, and two multi-stage telescopic cylinders 208 are symmetrically installed on the surface of the connecting plate 207. The telescopic ends of the multi-stage telescopic cylinders 208 are fixedly connected with adjusting blocks 212 through L-shaped rods. The two adjusting blocks 212 are respectively slidably connected in rectangular slide grooves 213 opened on the surfaces of the two switching plates 202. The surface of the first sliding block 501 is fixedly connected with a second sliding block 506, and the second sliding block 506 is slidably connected in a through groove opened inside the rectangular slide groove 213. A plurality of third springs 507 are evenly arranged on the surface of the first sliding block 501, and the two ends of the third spring 507 are respectively fixedly connected to the first sliding block 501 and the switching plate 202, and the second sliding block 506 is located inside the rectangular slide groove 213.

[0047] In this embodiment, after the switching plate 202 is rotated 90 degrees from the vertical state, one of the required lower rubber roller bodies 103 is located between the two switching plates 202, and the multi-stage telescopic cylinder 208 is extended until the adjustment block 212 squeezes one of the pair of second sliding blocks 506 in the rectangular slide groove 213 in the direction close to the ratchet column 502 and maintains this state. At this time, the first sliding block 501 enables the limiting flower rod 203 on the surface of the corresponding ratchet column 502 to rotate only in one direction. In this process, the third spring 507 is stretched, which is used to reset the second sliding block 506 after the adjustment block 212 leaves the surface of the second sliding block 506.

[0048] like Figure 6 , Figure 7 , Fig.11 As shown, the surface of the lower rubber roller body 103 is symmetrically provided with connecting blocks 210, and the connecting blocks 210 are rotatably connected to the lower rubber roller body 103 through the third bearing. The upper surface and the bottom surface of the connecting block 210 are both protrudingly provided with convex blocks 217, and the bottom surface of the connecting block 210 is symmetrically provided with positioning holes 215. The surface of the connecting block 210 is inlaid with counterweight blocks 216 near the bottom position, and the telescopic end of the multi-stage telescopic cylinder 208 is fixedly connected with an insert block 209. A plurality of drawers 218 are arranged inside the switching box 201, and the drawers 218 are slidably connected to the switching box 201 through a plurality of rectangular openings on the surface of the switching box 201. A plurality of positioning blocks 220 are fixedly connected to the inner bottom surface of the switching box 201, and the drawers 218 conflict with the positioning blocks 220. The surface of the drawers 218 is provided with two positioning slots 219, and the convex blocks 217 are engaged with the corresponding positioning slots 219.

[0049] In this embodiment, the convex block 217 on the surface of the connecting block 210 is engaged with the positioning groove 219 on the surface of the drawer frame 218, so that the lower rubber roller body 103 between the two connecting blocks 210 is kept stable inside the switching box 201, which is convenient for the switching plate 202 to rotate and grab through the limiting flower rod 203. The engagement of the plug block 209 with the positioning socket 215 allows the multi-stage telescopic cylinder 208 to be inserted into the positioning socket 215 during the extension process, thereby maintaining stability between the connecting block 210 and the multi-stage telescopic cylinder 208, that is, maintaining the movement of the lower rubber roller body 103. The drawer frame 218 and the switching box 201 are slidably connected through the rectangular opening so that the corresponding lower rubber roller The body 103 can be easily pulled out of the interior of the switching box 201 for maintenance or cleaning. The setting of the counterweight block 216 allows the positioning block 204 to support the positioning and coupling block 206 on the surface of the lower glue roller body 103 after the switching plate 202 is reset and rotated to a vertical state. At the same time, the connecting block 210 is rotated under the action of the gravity of the counterweight block 216 until the positioning hole 215 faces downward, so as to facilitate the insertion of the plug block 209 into the positioning hole 215. The function of the two isolation baffles 301 is to prevent a small amount of glue liquid evaporated in the gluing operation area as well as dust and debris from falling into the interior of the switching box 201, thereby contaminating the surface of the unused lower glue roller body 103, which will affect the gluing operation when it is used.

[0050] like Figure 3 and Figure 6 As shown, a box opening 221 is provided on the upper surface of the switching box 201, and isolation baffles 301 are symmetrically arranged inside the box opening 221. Inclined plates 302 are symmetrically fixedly connected to the surfaces of the isolation baffles 301. The two isolation baffles 301 are slidingly connected to the switching box 201 through second sliding grooves symmetrically provided inside the box opening 221. A plurality of first springs 303 are equidistantly arranged on the surface of the isolation baffles 301, and the two ends of the first springs 303 are fixedly connected to the switching box 201 and the isolation baffles 301, respectively. Four guide damping wheels 304 are installed on the surface of the switching box 201, and the guide damping wheels 304 are symmetrically arranged on both sides of the box opening 221.

[0051] In this embodiment, during the process of the lower rubber roller body 103 entering or leaving the switching box 201, the connecting block 210 will squeeze the surface of the inclined plate 302, causing the isolation baffle 301 to slide into the second slide groove opened in the switching box 201, so that the box opening 221 is not blocked. When the lower rubber roller body 103 needs to enter the switching box 201, the roller of the guide damping wheel 304 guides the two connecting blocks 210 on the surface of the lower rubber roller body 103, and through the rotational resistance of the roller of the guide damping wheel 304, it damps the falling process of the guide damping wheel 304, so that the positioning socket 215 at the bottom of the connecting block 210 and the plug block 209 are inserted into the process more smoothly, reducing the damage caused by rigid collision, and also guiding the connecting block 210, further stabilizing the insertion process of the positioning socket 215 and the plug block 209.

[0052] like Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 8 As shown, a support plate 601 is symmetrically arranged on the surface of the switching box 201, and the support plate 601 is fixedly connected to the switching box 201 and the housing 101. A linear slide 602 is arranged above the support plate 601, and a fixed block 604 is symmetrically fixedly connected to the surface of the linear slide 602. A plurality of constraint rods 605 are symmetrically arranged on both sides of the two linear slides 602. The constraint rods 605 are slidably connected to the fixed block 604 through a first circular hole opened on the surface of the fixed block 604 on the same side. Positive and negative screw rods 606 are arranged on the surface of the two fixed blocks 604 on one side, and the corresponding fixed blocks 604 are threadedly connected to the positive and negative screw rods 606 through threaded holes starting from the surface.

[0053] A second motor 404 is installed on the surface of the slider of the linear slide 602, and a power connecting block 401 is fixedly connected to the surface of the output shaft of the second motor 404. A connecting rod 402 is fixedly connected to the surface of the slide of the linear slide 602, and a plurality of guide support rods 610 are fixedly connected to the surface of the connecting rod 402. A support guide hole 214 corresponding to the guide support rod 610 is provided on the surface of the connecting block 210. A plurality of power connecting rods 405 are fixedly connected to the surface of the power connecting block 401. A plurality of power connecting holes 406 corresponding to the power connecting rods 405 are provided on the surface of the positioning and combining block 206, and the diameters of the positioning and combining blocks 206 are all different.

[0054] In this embodiment, when the lower glue roller body 103 moves to the top of the switching box 201, that is, it enters the glue coating operation area, the third motor 607 is controlled to operate so that the two fixed blocks 604 on the surfaces of the positive and negative screw rods 606 move toward each other, that is, the two linear slides 602 move toward each other, and the connecting rods 402 on the surfaces of the sliders of the two linear slides 602 move toward each other. During this process, part of the surface of the guide support rod 610 is inserted into the corresponding support guide hole 214 on the surface of the connecting block 210. At this time, the third motor 607 is controlled to stop running to avoid the movement of the power connecting rod 405 and the adjusting block 212. Dynamic interference controls the multi-stage telescopic cylinder 208 to contract, so that the adjustment block 212 leaves between the power connecting rod 405 and the positioning and combining block 206. At this time, the lower rubber roller body 103 is supported by the guide support rod 610 through the connecting block 210, and the third motor 607 is controlled to continue to run. The two linear slides 602 continue to approach each other until the power connecting rod 405 on the surface of the power connecting block 401 is inserted into the power connecting hole 406 on the surface of the positioning and combining block 206. At this time, the rotation of the output shaft of the second motor 404 can drive the lower rubber roller body 103 to rotate synchronously. The constraint rod 605 plays a role of guidance and support in the process of the linear slides 602 approaching or moving away from each other;

[0055] When the lower rubber roller body 103 is removed from the glue coating operation area, the third motor 607 is controlled to operate so that the two linear slides 602 move away from each other, and then the multi-stage telescopic cylinder 208 is controlled to extend so that the plug block 209 is inserted into the interior of the positioning socket 215. At this time, the adjustment block 212 is located between the power connecting rod 405 and the positioning combination block 206. At this time, the third motor 607 is controlled to operate so that the guide support rod 610 leaves the support guide hole 214. At this time, under the action of gravity and the damping action of the guide damping wheel 304, the plug block 209 is fully engaged with the positioning socket 215, and the multi-stage telescopic cylinder 208 is controlled to contract. During the falling process, the positioning combination block 206 on the surface of the lower rubber roller body 103 will pass through the positioning blocks 204 with a larger spacing until it is stuck in the corresponding two The multi-stage telescopic cylinder 208 continues to contract, and the insert block 209 leaves the interior of the positioning socket 215 until the adjustment block 212 limits the corresponding limiting flower rod 203 to a one-way rotation state through the second sliding block 506, and the first motor 211 is controlled to operate to rotate the switching plate 202 toward the drawer frame 218 corresponding to the lower rubber roller body 103 inside it, until the connecting block 210 on the surface of the lower rubber roller body 103 is engaged with the drawer frame 218 through the convex block 217. At this time, the multi-stage telescopic cylinder 208 is controlled to contract again, so that the adjustment block 212 leaves the surface of the corresponding second sliding block 506, and the limiting flower rod 203 in one-way rotation is released from the restriction and can rotate in both directions, and the first motor 211 is controlled to operate to reset the switching plate 202 to a vertical state.

[0056] like Figure 1 , Figure 2 and Figure 4 As shown, electric telescopic cylinders 603 are symmetrically installed on the surface of the support plate 601, and the output shaft of the electric telescopic cylinder 603 is fixedly connected to the corresponding fixed block 604. Four auxiliary slide grooves 615 are opened on the surface of the shell 101. The auxiliary slide grooves 615 are internally slidably connected with auxiliary sliders 614. The auxiliary sliders 614 are fixedly connected to the corresponding constraint rods 605 through the second circular holes opened on the surface. The forward and reverse screw rods 606 are located in the third circular holes opened on the surfaces of two of the auxiliary sliders 614. The surface of one of the auxiliary sliders 614 is installed with a third motor 607, and the output shaft of the third motor 607 is fixedly connected to the forward and reverse screw rods 606.

[0057] The upper surface of the switch box 201 is symmetrically fixed with four vertical plates 611, a lower track 612 is fixedly connected between two opposite vertical plates 611, the surfaces of the vertical plates 611 are fixedly connected with upper tracks 613, and the opposite surfaces of the lower tracks 612 and the upper tracks 613 are provided with wire grooves corresponding to the convex blocks 217.

[0058] In this embodiment, the height change of the linear slide 602 can be controlled by the extension and retraction of the electric telescopic cylinder 603, so that the lower glue roller body 103 is moved closer to the glue roller of the glue coating mechanism 102. The cooperation between the auxiliary slider 614 and the auxiliary slide groove 615 makes the movement of the linear slide 602 more stable. By setting the upper track 613 and the lower track 612 on the vertical plate 611, the movement of the lower glue roller body 103 is constrained by the convex block 217 on the surface of the connecting block 210 and the wire groove on the surface of the upper track 613 and the lower track 612, so that the movement of the lower glue roller body 103 is more stable.

[0059] It should be noted that: three rollers are arranged inside the gluing mechanism 102, the roller located in the middle is the metering roller, and the two rollers located on both sides of the metering roller are respectively the forward coating roller and the reverse coating roller. The rotation and movement of the three rollers are coordinated with the external driving device, which is well known in the prior art and will not be described in detail here. In this embodiment, the roller located on the left is the forward coating roller, and the roller located on the right is the reverse coating roller. The gluing mechanism 102 is used in conjunction with the glue groove (not shown in the figure) and the glue injection device (not shown in the figure), which is well known in the prior art and will not be described in detail here. The use method and working principle between the gluing mechanism 102 and the lower glue roller body 103 are well known in the prior art and will not be described in detail here.

[0060] The output shaft of the first motor 211 passes through the reserved hole on the surface of the switching box 201 and passes through the convex bearing to be fixedly connected to the switching plate 202, and the central axis of the output shaft of the first motor 211 coincides with the central axis of the convex bearing;

[0061] The roller of the guide damping wheel 304 has a certain rotation resistance, so that after the power connection block 401 is separated from the positioning and combining block 206, the falling speed of the lower rubber roller body 103 is slowed down, so that when the multi-stage telescopic cylinder 208 is extended to receive the falling lower rubber roller body 103, the adjustment block 212 does not interfere with the movement between the power connection block 401, the connecting rod 402 and the second motor 404;

[0062] In order to further adapt the device to various gluing processes, the vertical plate 611 can be replaced by a mechanism with a lifting function, such as an electric push rod, and the lower track 612 and the upper track 613 are fixedly connected to the telescopic end of the electric push rod;

[0063] The distance between the upper rail 613 and the lower rail 612 can also be increased so that the connecting block 210 between the two can move up and down a small distance, and during the up and down movement, the two protruding blocks 217 on the surface of the connecting block 210 are always located in the corresponding sliding grooves opened on the surfaces of the lower rail 612 and the upper rail 613;

[0064] A locking mechanism, such as a latch slot, may be provided between the drawer 218 and the switch box 201 to maintain stability between the drawer 218 and the switch box 201;

[0065] The side of each power connection hole 406 close to the power connection rod 405 is tapered, and the tapered parts between any two adjacent holes are connected, so that the power connection rod 405 can be inserted into the power connection hole 406 at any angle;

[0066] The linear slide 602 is composed of a plate body, a power motor, a lead screw and a slider threadedly connected to the lead screw. Its working principle is well known in the prior art and will not be described in detail here.

[0067] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
