A spacing-adjustable conduction roller mechanism

Abstract

The present invention discloses a spacing-adjustable transmission roller mechanism, comprising a base frame, two groups of front frames, and multiple groups of guide rollers. The two groups of front frames are fixedly connected to the base frame, and the tops of the two groups of front frames are slidably connected to support seats with an L-shaped structure. The tops of the horizontal ends of the two groups of support seats are fixedly installed with pushers, and the output ends of the pushers are fixedly installed with lifting plates. The outer walls of the multiple groups of guide rollers are sleeved with connecting frames. In the present application, as the spacing of the multiple groups of guide rollers increases, the transmission belt portion between the guide rollers and the mating wheels gradually straightens, and the mating wheels move vertically and compress spring 2, thereby ensuring that the transmission belts always remain straight. The driving member can still stably drive the multiple groups of guide rollers through the cooperation of the driving wheel and the transmission belt, thereby achieving spacing adjustment of the multiple groups of guide rollers while ensuring that the guide rollers can rotate stably.

Description

Technical Field

[0001] The present invention relates to the technical field of positioners, and in particular to a spacing-adjustable conductive roller mechanism. Background Art

[0002] Corrugated cardboard is a common material used in everyday cartons. It's a multi-layered, bonded structure consisting of at least one corrugated core paper layer and one cardboard layer. It possesses high mechanical strength, capable of withstanding bumps and drops during handling. Its performance depends on three factors: the properties of the core paper and cardboard, and the structure of the box itself. Corrugated cardboard has numerous uses in everyday life, and subsequent bundling and palletizing requires securing and positioning the sheets to ensure stable stacking.

[0003] Existing methods for positioning cardboard include positioners and manual processing. The existing positioner includes a base frame, a positioning box, a first conduction mechanism and a second conduction mechanism, wherein the first conduction mechanism is composed of a conduction roller mechanism and a horizontal positioning mechanism, and the horizontal positioning mechanism is fixedly matched with the positioning box on the outside, and the first conduction mechanism and the second conduction mechanism are provided with a blocking mechanism for blocking the cardboard, which is used to block the cardboard and cooperate with the baffle on the second conduction mechanism to perform longitudinal positioning of the cardboard.

[0004] The existing conductive roller mechanisms such as the above are mostly composed of a driving member, a guide roller member and a mounting plate. Multiple groups of guide roller members are integrated on the mounting plate. The mounting plate is fixedly matched with the base frame. The driving member drives the multiple groups of guide roller members to rotate simultaneously through the transmission belt. In the specific implementation process, when the previous cardboard is not completely positioned, the subsequent cardboard will be blocked on the conductive roller by the blocking mechanism. The overall width of the existing multiple groups of guide roller members is relatively limited and often cannot adapt to cardboards with larger widths. Therefore, it is urgent to propose a corresponding conductive roller mechanism with adjustable spacing to solve the above problems. Summary of the Invention

[0011] Preferably, the pushing component includes multiple groups of protrusions, which are fixedly connected to multiple groups of connecting frames respectively. The inner wall of the lifting plate is provided with multiple groups of matching grooves, which are distributed in a claw shape, and the multiple groups of matching grooves are slidingly connected to multiple groups of protrusions respectively.

[0012] Preferably, the second pushing component includes a flange and a fixing seat, the flange and the lifting plate are integrally formed, and the fixing seat is fixedly installed at the bottom of the cross bar, and the arc-shaped end of the flange is slidably matched with the inclined surface of the fixing seat.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0016] 1. In the present application, the lifting plate is driven to rise by the pushing member, and the multiple sets of matching grooves on the inner surface wall of the lifting plate are respectively slidably matched with the multiple sets of protrusions. As the matching positions of the matching grooves and the protrusions are switched, the multiple sets of protrusions respectively drive the corresponding connecting frames to move, that is, the horizontal position of the connecting frame connected in the middle remains unchanged, while the connecting frames on both sides perform equal distance relative movement, and the multiple sets of connecting frames are respectively linked to the multiple sets of guide rollers, and in this process, the flange on the outer side of the lifting plate is slidably matched with the inclined surface of the fixed seat, so that the overall support seat slides a specified distance along the direction of extension of the guide rail, and the sliding sleeve synchronously moves along the light rod Slide and compress spring one to fit the adjustment rule of the guide roller, so that a group of guide rollers close to the cross bar always maintain a fixed distance from the second transmission mechanism on the outside, so as not to affect the cooperation between the two.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0026] See also Figure 1-5 , the present invention provides a technical solution:

[0027] A spacing-adjustable conduction roller mechanism comprises a base frame 1, two groups of front frames 2 and multiple groups of guide rollers 13, the two groups of front frames 2 are fixedly connected to the base frame 1, the tops of the two groups of front frames 2 are slidably connected to support seats 3 with an L-shaped structure, the tops of the horizontal ends of the two groups of support seats 3 are fixedly installed with pushers 8, the output ends of the pushers 8 are fixedly installed with lifting plates 10, the outer walls of the multiple groups of guide rollers 13 are sleeved with connecting frames 14, the outside of the support seats 3 is provided with a limiting component for vertically limiting the connecting frame 14, a pushing component 1 for horizontal movement of the connecting frame 14 is provided between the connecting frame 14 and the lifting plate 10, and a driving component for driving the multiple groups of guide rollers 13 is provided at the vertical ends of the two groups of support seats 3, a cross bar 4 is fixedly installed on the inner surface wall of the base frame 1, and a pushing component 2 for longitudinally pushing the support seat 3 is provided between the cross bar 4 and the lifting plate 10;

[0028] The lifting plate 10 is driven to rise by the pushing member 8, and the multiple sets of matching grooves 19 on the inner wall of the lifting plate 10 are respectively slidably matched with the multiple sets of protrusions 18. As the matching positions of the matching grooves 19 and the protrusions 18 are switched, the multiple sets of protrusions 18 respectively drive the corresponding connecting frames 14 to move, that is, the horizontal position of the middle connecting frame 14 remains unchanged, while the connecting frames 14 on both sides perform equal distance relative movement, and the multiple sets of connecting frames 14 are respectively linked to the multiple sets of guide rollers 13, and in this process, the flange 11 on the outer side of the lifting plate 10 is slidably matched with the inclined surface of the fixed seat 12, so that the overall support seat 3 will slide a specified distance along the direction of extension of the slide rail 9, and the sliding sleeve 15 synchronously slides along the light rod 6 and compresses the spring 17 to fit the guide roller 13 The adjustment rule makes the group of guide roller members 13 close to the cross bar 4 always maintain a fixed distance from the second transmission mechanism on the outside, so as not to affect the cooperation between the two. At the same time, as the spacing between the multiple groups of guide roller members 13 increases, the part of the transmission belt 17 located between the guide roller member 13 and the matching wheel 21 gradually becomes straight, and the matching wheel 21 will move vertically and compress the spring 24, so as to ensure that the transmission belt 17 always remains in a straight state. The driving member 16 can still stably drive the multiple groups of guide roller members 13 through the cooperation of the driving wheel 22 and the transmission belt 17, so as to achieve the spacing adjustment of the multiple groups of guide roller members 13 under the premise of ensuring the stable rotation of the guide roller member 13, so that the width of the overall transmission roller mechanism can be conveniently adjusted according to the needs of use.

[0029] Specifically, such as Figure 2 and Figure 4 As shown, multiple groups of connecting frames 14 are rotationally connected to multiple groups of guide rollers 13 through multiple groups of bearings respectively. The limiting assembly includes a limiting frame 5. The outer wall of the limiting frame 5 is slidingly connected to the inner wall of the vertical end of the multiple groups of connecting frames 14. The connecting frame 14 is rotationally matched with the guide roller 13 through the bearing, so as not to hinder the rotation of the guide roller 13 and realize the horizontal linkage of the connecting frame 14 and the guide roller 13. At the same time, the limiting frame 5 is fixedly installed on the vertical end of the support seat 3. The limiting frame 5 is slidingly matched with the multiple groups of guide rollers 13 at the same time, so that when the protrusion 18 and the matching groove 19 slide between the lifting plate 10 and the connecting frame 14, the connecting frame 14 will not be vertically offset and will not hinder the horizontal movement of the connecting frame 14, thereby ensuring the stability of the use of the adjustable spacing conduction roller mechanism.

[0030] Specifically, such as Figure 2 and Figure 3As shown, the driving assembly includes a driving member 16 fixedly connected to the vertical end of the support seat 3, and a driving wheel 22 is fixedly installed on the output end of the driving member 16. A matching wheel 21 is provided on the outer wall of the vertical end of the support seat 3. The driving wheel 22 is connected to multiple groups of matching wheels 21 and the guide roller member 13 through a transmission belt 17. An embedded seat 20 is embedded in the vertical end of the support seat 3, and a slider 23 is slidably connected to the inner wall of the embedded seat 20, and a spring 24 is fixedly installed between the slider 23 and the embedded seat 20. The slider 23 rotates in coordination with the matching wheel 21. As the spacing between the multiple groups of guide roller members 13 increases, the part of the transmission belt 17 between the guide roller member 13 and the matching wheel 21 gradually becomes straight, and the matching wheel 21 will drive the slider 23 to move vertically. The slider 23 compresses the spring 24, thereby ensuring that the transmission belt 17 always remains in a straight state. The driving member 16 can still stably drive multiple groups of guide roller members 13 through the cooperation of the driving wheel 22 and the transmission belt 17.

[0031] Specifically, such as Figure 1 and Figure 2 As shown, the pushing component 1 includes multiple groups of protrusions 18, and the multiple groups of protrusions 18 are fixedly connected to the multiple groups of connecting frames 14 respectively. The inner surface wall of the lifting plate 10 is provided with multiple groups of matching grooves 19, and the multiple groups of matching grooves 19 are claw-shaped. The multiple groups of matching grooves 19 are respectively slidably connected with the multiple groups of protrusions 18. The pushing member 8 drives the lifting plate 10 to rise, and the multiple groups of matching grooves 19 on the inner surface wall of the lifting plate 10 are respectively slidably matched with the multiple groups of protrusions 18. As the matching positions of the matching grooves 19 and the protrusions 18 switch, the multiple groups of protrusions 18 respectively drive the corresponding connecting The frame 14 moves, that is, the horizontal position of the middle connecting frame 14 remains unchanged, while the connecting frames 14 on both sides move relative to each other at an equal distance. The pushing component 2 includes a flange 11 and a fixed seat 12. The flange 11 and the lifting plate 10 are integrally formed, and the fixed seat 12 is fixedly installed at the bottom of the cross bar 4. The arcuate end of the flange 11 slides with the inclined surface of the fixed seat 12, and the flange 11 on the outer side of the lifting plate 10 slides with the inclined surface of the fixed seat 12, so that the overall support seat 3 will slide a specified distance along the direction in which the slide rail 9 extends.

[0032] Specifically, such as Figure 1 and Figure 2 As shown, a slide is fixedly installed at the bottom of the support seat 3, and a slide rail 9 is fixedly installed at the top of the front frame 2. The slide and the slide rail 9 slide in cooperation to ensure the stable movement of the support seat 3. A light rod 6 is fixedly installed on the inner wall of the front frame 2, and a sliding sleeve 15 that slides in cooperation with the light rod 6 is fixedly installed at the bottom of the support seat 3, and a spring 7 is fixedly installed between the sliding sleeve 15 and the front frame 2, so as to conform to the movement law of the support seat 3 while realizing self-positioning of the support seat 3 through the spring 7.

[0033] Working principle: The lifting plate 10 is driven to rise by the pushing member 8, and the multiple sets of matching grooves 19 on the inner wall of the lifting plate 10 are respectively slidably matched with the multiple sets of protrusions 18. As the matching positions of the matching grooves 19 and the protrusions 18 are switched, the multiple sets of protrusions 18 respectively drive the corresponding connecting frames 14 to move, that is, the horizontal position of the middle connecting frame 14 remains unchanged, while the connecting frames 14 on both sides perform equal distance relative movement, and the multiple sets of connecting frames 14 are respectively linked to the multiple sets of guide rollers 13, and in this process, the flange 11 on the outer side of the lifting plate 10 is slidably matched with the inclined surface of the fixed seat 12, so that the entire support seat 3 will slide a specified distance along the extension direction of the slide rail 9, and the sliding sleeve 15 synchronously slides along the light rod 6 and compresses the spring 7, thereby conforming to the adjustment rule of the guide roller 13, so that the group of guide rollers 13 close to the cross bar 4 always maintains a fixed distance with the second transmission mechanism on the outside, so as not to affect the cooperation between the two, and at the same time, as the spacing between the multiple sets of guide rollers 13 increases, the transmission mechanism between the guide roller 13 and the matching wheel 21 The moving belt 17 gradually becomes straight, and the matching wheel 21 will move vertically and compress the spring 24, so as to ensure that the transmission belt 17 always remains in a straight state. The driving member 16 can still stably drive the multiple groups of guide rollers 13 through the cooperation of the driving wheel 22 and the transmission belt 17, so as to achieve the spacing adjustment of the multiple groups of guide rollers 13 while ensuring the stable rotation of the guide rollers 13, so that the width of the overall transmission roller mechanism can be conveniently adjusted according to the needs of use. The connecting frame 14 rotates with the guide rollers 13 through the bearings, so as not to hinder the rotation of the guide rollers 13, and can achieve horizontal linkage between the connecting frame 14 and the guide rollers 13. At the same time, the limiting frame 5 is fixedly installed on the vertical end of the support seat 3, and the limiting frame 5 is slidably cooperated with the multiple groups of guide rollers 13 at the same time, so that when the protrusion 18 and the matching groove 19 slide between the lifting plate 10 and the connecting frame 14, the connecting frame 14 will not be vertically offset and the horizontal movement of the connecting frame 14 will not be hindered, thereby ensuring the stability of the transmission roller mechanism with adjustable spacing.
