[0002] During the processing of paper products (such as paper boxes, leather cases, etc.), cardboard (such as gray board, etc.) can be pushed by the pusher mechanism for subsequent processing. For example, in production equipment such as slotting machines, paper box forming machines, and leather cases machines, the cardboard on the paper feed rail is pushed by the pusher unit in the pusher mechanism. Among them, the cardboard pusher mechanism has multiple pusher unit devices. Due to many reasons such as different sizes of cardboards and displacement adjustment of paper feed rails, the relative position of the pusher unit device needs to be adjusted to meet the pushing requirements.

In addition, it is difficult for the staff of downstream paper product manufacturers to adjust it, and it needs to be adjusted by professional maintenance personnel of the equipment manufacturer.

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the implementation of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field without making creative work based on the embodiments of the utility model are within the scope of protection of the utility model.

[0027] Referring to the accompanying drawings, the cardboard pusher mechanism in the embodiment of the present embodiment includes a longitudinally moving plate 1 and at least two pusher devices 2. The pusher devices 2 are connected to the longitudinally moving plate 1. The pusher devices 2 can move longitudinally with the longitudinally moving plate 1 to cooperate with the conveying cardboard to move longitudinally. The pusher device 2 includes a pusher unit 3. Generally, the pusher unit 3 is configured as a pusher block (different types of pusher blocks can be selected according to needs). Multiple pusher units 3 can stably push cardboard and can also meet the needs of pushing multiple cardboards at the same time.

[0028] A transverse track 4 (such as a transversely arranged linear guide rail) is provided on the longitudinal moving plate 1, and the push head unit 3 is connected and configured on the transverse track 4. The push head unit 3 can move laterally along the transverse track 4 to achieve accurate and stable adjustment of the transverse position.

[0029] A pressure bearing friction plate 5 is also provided on the longitudinal moving plate 1, and a pressure bearing friction surface 6 is provided on the pressure bearing friction plate 5 so as to bear pressure and friction fit. The pressure bearing friction plate 5 moves together (longitudinally) with the longitudinal moving plate 1.

[0030] The push head device 2 also includes an elastic pressure rod 7 and a pressure rod pressure elastic component 8; each push head unit 3 is respectively connected to a corresponding elastic pressure rod 7, that is, the push head unit 3 is paired with the elastic pressure rod 7, and the elastic pressure rod 7 and the corresponding push head unit 3 can move laterally synchronously; each elastic pressure rod 7 is connected to a corresponding pressure rod pressure elastic component 8, that is, the elastic pressure rod 7 is paired with the pressure rod pressure elastic component 8, and the pressure rod pressure elastic component 8 cooperates to apply elastic force to the elastic pressure rod 7, and under the action of the elastic force, the elastic pressure rod 7 is pressed onto the pressure friction surface 6 of the pressure friction plate 5. Among them, each elastic pressure rod 7 is arranged in correspondence with the pressure-bearing friction surface 6, the head of the elastic pressure rod 7 is the pressure end 9, and the pressure end 9 of each elastic pressure rod 7 faces the pressure-bearing friction surface 6. Under the action of the elastic force applied by the pressure rod pressure elastic component 8, the elastic pressure rod 7 can pressurize the pressure-bearing friction surface 6, and the pressure end 9 keeps in contact with the pressure-bearing friction surface 6. There is an interaction force (pressure and friction) between the elastic pressure rod 7 (the pressure end 9 of its head) and the pressure-bearing friction surface 6, and the pressure-bearing friction surface 6 on the pressure-bearing friction plate 5 can cooperate with pressure (bearing pressure such as the elastic pressure rod 7) and cooperate with (pressure end 9 such as the elastic pressure rod 7) friction to form damping.

[0031] Among them, the pressure-bearing friction surface 6 of the pressure-bearing friction plate 5 is arranged laterally, that is, the pressure-bearing friction surface 6 is a transverse surface, so that when the push head unit 3 and the elastic pressure rod 7 move laterally together, the elastic pressure rod 7 (its pressure end 9) always keeps in contact with the pressure-bearing friction surface 6, and the head of the elastic pressure rod 7 (its pressure end 9) can always move laterally against the transversely arranged pressure-bearing friction surface 6 and always maintain interaction.

[0032] Among them, the push head device 2 cooperates with the pressure-bearing friction plate 5, and the elastic pressure rod 7 always keeps in contact with the pressure-bearing friction surface 6, and there is an interaction force (pressure and friction). When the lateral position of the push head unit 3 needs to be adjusted, the push head unit 3 can overcome the friction force (between the elastic pressure rod 7 and the pressure-bearing friction surface 6 of the pressure-bearing friction plate 5) and push the push head unit 3 to move laterally along the lateral track 4; under the interaction force (pressure and friction), after the push head unit 3 (with the elastic pressure rod 7) moves laterally to the required position (release the push), the push head unit 3 can immediately stay stably at the required position, and then move longitudinally with the longitudinal moving plate 1 to push the cardboard without lateral position shifting. Pushing the push head unit 3 can be done by pure manual pushing, or it can be driven by the lateral movement of other components in the equipment (such as paper feeding rails, etc.), so that the cardboard push head mechanism does not need to be equipped with additional power (such as motors or cylinders, etc.) to promote lateral adjustment.

[0033] In the cardboard pushing head mechanism, the lateral adjustment of the pushing head unit 3 is relatively convenient. When the elastic pressure rod 7 and the pressure-bearing friction surface 6 are always in contact, there is an interaction force (pressure and friction) between the elastic pressure rod 7 and the pressure-bearing friction surface 6. The pushing head unit 3 can be directly pushed to adjust the position laterally while overcoming the friction force. After the position is adjusted, the pushing head unit 3 can stay in the required position in a timely and stable manner under the action of pressure and friction. When the elastic pressure rod 7 and the pressure-bearing friction surface 6 have an interaction force (pressure and friction), the pushing head unit 3 will not shift its position laterally when it moves longitudinally with the longitudinal moving plate 1 to push the cardboard. When the pushing head unit 3 is adjusted laterally, the pressure-bearing friction plate 5 does not need additional action. For example, the pressure-bearing friction plate 5 does not need additional power operation (such as a motor or a cylinder, etc.). During the lateral adjustment of the pushing head unit 3, the relative position of the pressure-bearing friction plate 5 remains unchanged. The lateral position adjustment of the pushing head unit 3 is more convenient, the failure rate is lower, and the stability is relatively higher.

[0034] The following optimization or further explanation may be performed based on the above embodiments.

[0035] For example, the pressure friction plate 5 is fixedly connected and installed on the longitudinal plate 1 in an unadjustable manner, that is, the pressure friction plate 5 is fixedly connected and installed on the longitudinal plate 1, and the relative position of the pressure friction plate 5 and the longitudinal plate 1 remains unchanged, and the relative position cannot be adjusted. The fixed installation ensures that the relative position of the pressure friction plate 5 on the longitudinal plate 1 remains unchanged during the lateral adjustment of the push head unit 3 and the longitudinal plate 1 and the push head unit 3 push the cardboard, and the pressure friction plate 5 and the longitudinal plate 1 move longitudinally synchronously; ensuring that the relative position of the pressure friction plate 5 (and its pressure friction surface 6) remains unchanged during the lateral adjustment of the push head unit 3. The non-adjustable fixed connection installation setting, the pressure-bearing friction plate 5 can be pre-set to a suitable position and then fixedly connected, ensuring that the elastic force of the pressure rod pressure elastic component 8 is just right, and the mutual force (pressure and friction) between the elastic pressure rod 7 and the pressure-bearing friction surface 6 is just right, ensuring that the elastic pressure rod 7 and the pressure-bearing friction surface 6 are always in contact with each other, and can overcome the friction force under the action of other external forces (such as manual pushing) to directly push the push head unit 3 to adjust the position laterally, and after the push head unit 3 adjusts its position, it will stay in the required position in a timely and stable manner under the force (pressure and friction) between the elastic pressure rod 7 and the pressure-bearing friction surface 6, and the push head unit 3 can move longitudinally with the longitudinal moving plate 1 to cooperate with the cardboard pushing without lateral position displacement.

[0036] Or, for example, the pressure-bearing friction plate 5 is adjustable and fixedly connected and installed on the longitudinal plate 1, that is, the pressure-bearing friction plate 5 is fixedly connected and installed on the longitudinal plate 1, and the relative position of the pressure-bearing friction plate 5 and the longitudinal plate 1 can be adjusted according to demand; when in use, the relative position is adjusted and then the pressure-bearing friction plate 5 is fixedly connected and installed on the longitudinal plate 1. The fixed installation ensures that the relative position of the pressure-bearing friction plate 5 on the longitudinal plate 1 remains unchanged during the lateral adjustment of the push head unit 3, and during the longitudinal plate 1 and the push head unit 3 push the cardboard, and the pressure-bearing friction plate 5 moves longitudinally synchronously with the longitudinal plate 1. Ensure that the relative position of the pressure-bearing friction plate 5 (and its pressure-bearing friction surface 6) remains unchanged during the lateral adjustment of the push head unit 3. The adjustable fixed connection installation setting can pre-adjust the relative position of the pressure-bearing friction plate 5 on the longitudinal movement plate 1 and then fix it, and can be released and adjusted and fixed again at any time according to needs. By adjusting the relative position of the pressure-bearing friction plate 5 on the longitudinal movement plate 1, the mutual force (pressure and friction) between the pressure-bearing friction surface 6 of the pressure-bearing friction plate 5 and the elastic pressure rod 7 can be adjusted to meet the requirements that the elastic force of the pressure rod pressure elastic component 8 is just right, and the mutual force (pressure and friction) between the elastic pressure rod 7 and the pressure friction surface 6 is just right, avoiding direct pre-setting The position of the pressure-bearing friction plate 5 cannot be satisfied, or the situation that it cannot be satisfied after long-term use is found. It is more practical and can better ensure that the elastic pressure rod 7 and the pressure-bearing friction surface 6 are always in contact with each other. It can also overcome the friction force under the action of other external forces (such as manual pushing) to directly push the push head unit 3 to adjust the position laterally. After the push head unit 3 adjusts its position, it can stay in the required position in a timely and stable manner under the force (pressure and friction force) (between the elastic pressure rod 7 and the pressure-bearing friction surface 6). The push head unit 3 can move longitudinally with the longitudinal moving plate 1 and cooperate with the cardboard pushing without lateral position displacement.

[0037] For example, the longitudinal plate 1 is provided with an adjustment locking seat 10 (or an adjustment tension seat), and the pressure friction plate 5 is connected with a position adjustment moving rod 11, and the pressure friction plate 5 and the position adjustment moving rod 11 are moved and adjusted together, wherein the position adjustment moving rod 11 is connected to the adjustment locking seat 10, and the position adjustment moving rod 11 can be moved and adjusted on the adjustment locking seat 10, and can also be locked and released by the adjustment locking seat 10, when released, the pressure friction plate 5 and the position adjustment moving rod 11 can be moved and adjusted together, and after the position movement and adjustment is completed, the position adjustment moving rod 11 is locked and fixed by the adjustment locking seat 10. In this way, the pressure friction plate 5 can be adjusted and fixedly connected and installed on the longitudinal plate 1.

[0038] For example, the adjusting locking seat 10 is provided with a locking hole 12 and a locking groove 13, the locking groove 13 is connected with the locking hole 12, the position adjustment moving rod 11 is connected and passes through the locking hole 12, and the locking groove 13 is also provided with a locking fastener (such as a locking screw or a locking bolt nut, etc.), the locking fastener is connected to the adjusting locking seat 10, the position adjustment moving rod 11 can be moved in the locking hole 12 for position adjustment, and then the locking fastener is coordinated with the size of the loosening and tightening locking groove 13, so that the locking hole 12 can loosen or tighten the corresponding position adjustment moving rod 11. Among them, the adjusting locking seat 10 includes a locking pressure block 14 and a base 15, the locking hole 12 and the locking groove 13 are both located between the locking pressure block 14 and the base 15, when locked, the locking pressure block 14 and the base 15 clamp the position adjustment moving rod 11, and when loosened, the locking pressure block 14 and the base 15 loosen the position adjustment moving rod 11. Among them, the locking block 14 is provided with a first connecting hole 16, the base 15 is provided with a second connecting hole, and the locking fastener connects the first connecting hole 16 and the second connecting hole. In addition, it can be optimized, the locking block 14 is integrally connected with one end of the base 15, which is convenient for installation, and even the adjustment locking seat 10 is provided with a guide hole 17, the guide hole 17 is aligned with the locking hole 12, the position adjustment moving rod 11 is connected and passes through the guide hole 17, and the position adjustment moving rod 11 also passes through the locking hole 12. When the locking hole 12 is loosened, the adjustment moving rod will not shake, ensuring that the position adjustment movement process is more accurate, avoiding shaking and displacement, and the structure is more compact. They are all located on the adjustment locking seat 10 and can be installed on the longitudinal moving plate 1 together, which is more convenient to assemble. Of course, in addition to the above locking methods, other locking methods can also be used, such as using top screws.

[0039] It can also be optimized, with the push head unit 3 located on the upper side of the longitudinal moving plate 1 and the pressure friction plate 5 located on the lower side of the longitudinal moving plate 1 . The upper side of the longitudinal moving plate 1 is simpler and has a relatively larger space; even the adjustment locking seat 10 is also located on the lower side of the longitudinal moving plate 1 .

[0040] In addition, each elastic pressure rod 7 and the pressure-bearing friction surface 6 can be arranged in a front-to-back corresponding manner. For example, in the figure, the corresponding elastic pressure rod 7 is arranged longitudinally, and the head (pressure end 9) of the front elastic pressure rod 7 faces the rear pressure-bearing friction surface 6. The pressure-bearing friction plate 5 can adjust the position forward and backward to achieve the change and adjustment of the force (pressure and friction force); it can even be optimized, and the front surface of the longitudinal plate 1 and the pressure-bearing friction surface 6 are parallel to each other (for example, both use transverse planes). When the pressure-bearing friction plate 5 (and the pressure-bearing friction surface 6) are located on the lower side of the longitudinal plate 1, it is convenient to adjust the setting. With the front surface of the longitudinal plate 1 as a reference, it is more convenient to adjust the setting relative to the pressure-bearing friction surface 6. Alternatively, each elastic pressure rod 7 and the pressure-bearing friction surface 6 can be arranged in a top-to-bottom corresponding manner, and the pressure-bearing friction plate 5 can adjust the position up and down to achieve the change and adjustment of the force. These two methods have a reasonable relative structural layout, convenient assembly, and relatively easy force adjustment; of course, they can also correspond obliquely. The pressure-bearing friction surface 6 is set as a plane, for example, a vertical plane is used in the figure (the plane is more stable when combined with the elastic pressure rod 7), of course, planes with other orientations (such as an oblique plane) can also be used, and plane processing is relatively simple.

[0041] In addition, the push head device 2 also includes a transverse adjustment seat 18, which is arranged on the transverse track 4, and the transverse adjustment seat 18 is additionally provided on the transverse track 4. Each push head unit 3 is respectively connected and arranged on the transverse track 4 through the corresponding transverse adjustment seat 18, and the corresponding pressure rod pressure elastic component 8 is connected between the corresponding elastic pressure rod and the corresponding transverse adjustment seat 18. The push head unit 3 is installed on the transverse adjustment seat 18, and the push head unit 3 can be laterally moved and adjusted relative position on the transverse track 4 with the transverse adjustment seat 18. The push head unit 3 can change the specification or style structure according to the demand, which has little effect on the structure of the entire cardboard push head mechanism, and will not affect the matching relationship between the pressure pressure elastic component, the elastic pressure rod 7, the pressure friction plate 5 and its pressure friction surface 6. Among them, the elastic pressure rod, the pressure rod pressure elastic component 8 and the transverse adjustment seat 18 correspond to each other, and cooperate to form the corresponding push head device 2. The transverse adjustment seat 18 can be set separately (that is, it contains multiple connected parts), or it can be an integrated structure, which can be set according to the demand. It can even be optimized that in some cardboard pusher mechanisms, the pusher unit 3 can perform additional lifting actions on the transverse adjustment seat 18.

[0042] After further optimization, the push head unit 3 is set to be adjusted front and back longitudinally on the transverse adjustment seat 18, and the position can be fine-tuned front and back, so that the cardboard can be pushed more accurately. The front and back longitudinal adjustment method can be adopted by setting a longitudinal long hole 22 or a long groove on the push head unit 3 to cooperate with the assembly holes such as the transverse adjustment seat 18 connected to the fastener.

[0043] It can also be further optimized. The transverse adjustment seat 18 is provided with a guide component 19 for the pressure rod to extend and apply pressure. The elastic pressure rods 7 are arranged parallel to each other. The elastic pressure rods 7 are connected to the guide component 19, and the guide component 19 cooperates to guide the axial movement of the elastic pressure rod 7. The pressure rod presses the elastic component 8 so that the elastic pressure rod 7 applies pressure toward the pressure-bearing friction surface 6. The elastic pressure rod 7 is also provided with a pressure rod extension stop point limiting component 20. In the unassembled state, the elastic pressure rod 7 can be limited when it is extended on the transverse adjustment seat 18, so as to avoid the push head device 2 from falling apart, and facilitate assembly and maintenance and replacement; wherein, the pressure rod extension stop point limiting component 20 is connected to the tail of the elastic pressure rod 7, the head of the elastic pressure rod 7 (having the pressure end 9) is located on one side of the guide component 19, and the tail of the elastic pressure rod 7 is located on the other side of the guide component 19. For example, the guide component 19 includes a guide sleeve or a guide through hole, the pressure rod pressure elastic component 8 includes a spring (such as a compression spring), the spring sleeve is arranged on the elastic pressure rod 7, the spring is located between the pressure end 9 (elastic pressure rod 7) and the guide component 19, the pressure rod extension stop limit component 20 includes a limit retaining ring, which can be connected to the elastic pressure rod 7 (such as the mounting hole 23) by a fastener, and the limit retaining ring is connected and installed at the tail of the elastic pressure rod 7. In addition, the pressure end 9 can also be provided with a friction pad 21 (such as a rubber pad, a rubber pad, etc.) to increase the friction damping effect.
