Description

Technical Field

[0001] The utility model relates to the technical field of paper stacking machine components, in particular to a paper supporter for a paper towel stacking machine. Background Art

[0002] Pull-out tissues are one of the most commonly used items in daily life, meeting people's daily cleaning needs. Pull-out tissues require a paper folding machine for processing and production. Specifically, the rolls of paper are conveyed, folded, and packaged to form the finished product. For example, Chinese utility model patent publication number CN202464246U discloses a pull-out facial tissue folding machine, which includes an automatic tissue folding mechanism / an automatic surface tissue folding mechanism, and an automatic sorting and conveying mechanism. After the paper is folded to the required number of layers, the paper support plate used to receive the folded paper moves rapidly downward, while the inserting plate 4 maintains its speed, increasing the distance between the two mechanisms and allowing the paper to fold. Simultaneously, an auxiliary paper support plate is inserted from the other side of the paper support plate, replacing the paper support plate to drag the paper downward. After the auxiliary paper support plate is in place, the inserting plate moves outward and away, then moves upward to wait for the next cycle to begin. As the paper is folded, the folding inserting plate moves together with the auxiliary paper support plate. The auxiliary paper support plate and the folding inserting plate cooperate to complete the folding of the lower layer of paper. After folding to a predetermined number of layers, the paper support board rises and replaces the auxiliary paper support board to support the paper towels folded into a predetermined number of layers. At this time, the auxiliary paper support board is pushed out, and when the paper support board drops rapidly, the auxiliary support board extends to receive the paper towels on the upper side, thereby completing the folding and transfer of the paper towels.

[0003] However, during the production process, the applicant discovered that during the long-term operation of the paper stacking machine, intermittent failures such as increased assembly clearance, slowed system program operation speed due to excessive system operation time, or unstable current and voltage can easily cause the sensitivity of the detection component for detecting the number of stacked layers to decrease, thereby increasing the number of paper towels on the auxiliary paper support plate, causing the auxiliary paper support plate to bend; or when the auxiliary paper support plate cannot be smoothly lowered, paper towels on the upper side continue to be stacked, causing the auxiliary paper support plate to bend. The above situation is difficult to avoid in the actual production process. The current solution to this problem is to replace the auxiliary paper support plate after the machine is shut down, which greatly prolongs the production time of the equipment and increases the cost of equipment maintenance.

[0004] Therefore, there is an urgent need for a paper towel stacking machine paper support to solve the above technical problems. Summary of the Invention

[0005] The purpose of this utility model is to provide a paper support for a paper towel stacking machine. In order to solve the above technical problems, this utility model adopts the following technical solutions:

[0006] A paper support device for a paper towel stacking machine includes two mutually opposed paper support mechanisms, wherein the paper support mechanisms include:

[0007] A support member, the support member is vertically arranged, and the lower end of the support member is used for fixed connection with the paper stacking machine;

[0008] A paper supporting member, the paper supporting member is horizontally arranged and rotatably connected to the upper end of the support member, and the two ends of the paper supporting member respectively constitute a pulling end and a paper supporting end;

[0009] An elastic member, one end of which is connected to the pulling end, and the other end of which is connected to the supporting member, so that the paper supporting member is in a horizontal state.

[0010] Furthermore, the paper support comprises

[0011] A main rod, one end of which is rotatably connected to the upper end of the support member, and the other end of which extends away from the support member to form a paper supporting end;

[0012] A pulling rod is threadedly connected to one end of the main rod rotatably connected to the support member and is defined as the pulling end.

[0013] Furthermore, a fixing member corresponding to the pulling rod is provided on the support member, one end of the fixing member is connected to the support member, and the other end extends in a horizontal direction away from the support member.

[0014] Furthermore, a connecting block is formed at the upper end of the support member, and limiting platforms are respectively provided on two opposite sides of the connecting block. A protrusion is formed on the end of the main rod, and the protrusion is rotatably connected to the connecting block, and a docking platform is formed at the end of the protrusion, which corresponds to the limiting platform and abuts against it to prevent the main rod from tilting.

[0015] Furthermore, the limit platform is formed with a guide surface inclined downward on one side edge facing the main rod, and the raised portion is formed with a surface corresponding to the guide surface and mating with each other along the guide surface on one side edge facing the paper supporting end.

[0016] Furthermore, the docking surface is configured to have an arc surface.

[0017] Furthermore, the two paper supporting members are arranged alternately with each other.

[0018] Furthermore, the lower side of the paper supporting end of at least any one of the paper supporting members is configured as an inclined slope, so that the thickness of the paper supporting end gradually decreases along the extending direction.

[0019] The beneficial effects produced by the utility model are as follows:

[0020] In the process of supporting the paper towels, the paper supporting member is kept in a horizontal state under the elastic pull of the elastic member, so that it can be used to support the paper towels. During the normal operation of the paper stacking machine, after the supported paper towels are stacked to a predetermined number of layers, the paper supporting mechanism is driven by the driving device of the paper stacking machine to withdraw sideways so that the paper towels can be placed on the components located below for transportation; after the paper stacking machine has an intermittent failure, since the number of paper towels stacked on the paper supporting member cannot be controlled, when the stacking amount of paper towels gradually increases and exceeds the predetermined required number of layers, the paper supporting member will overcome the elastic pull of the elastic member under the action of gravity and continue to tilt downward along the pivot, thereby moving the paper towels stacked on the paper supporting member downward, causing the paper towels to be scattered on the components below, thereby triggering the alarm to stop the paper stacking machine. At this time, the paper support mechanism has a rotating connection between the paper support and the support member, and the elastic member elastically pulls the paper support member to keep it horizontal to facilitate receiving paper towels. After an intermittent fault occurs, the paper support member is pressed down by the weight of the paper towels into an inclined state, thereby scattering the paper towels downward, thereby preventing them from being damaged by the paper towels, thereby reducing the need for component replacement and maintenance costs. It is conceivable that by selecting elastic members with different elastic coefficients, it can be matched with paper towels with different layer requirements. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings. The contents mentioned in the embodiments are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.

[0024] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings. The contents mentioned in the embodiments are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.

[0025] The embodiment of the present utility model provides a paper towel folding and paper support device, which is used to support paper towels folded together during the production and processing of pull-out paper towels. After a jam, a detection signal failure or other intermittent failure occurs, the paper support device continuously receives stacked paper towels, and the paper support member 200 falls under the stacked paper towels, thereby triggering an equipment alarm to avoid the paper towels being crushed by gravity, thereby avoiding delays in production due to replacement of accessories and increased maintenance costs.

[0026] like Figure 1-2 As shown, a paper support for a paper towel stacking machine includes two paper support mechanisms opposed to each other, so that it can support the paper towels on both sides to ensure the stability of the supported paper towels. Each paper support mechanism includes a support member 100, a paper support member 200 and an elastic member 300, wherein the support member 100 is vertically arranged, and its lower end is used to be fixedly connected to the paper stacking machine; the paper support member 200 is horizontally arranged and rotatably connected to the upper end of the support member 100, and the two ends of the paper support member 200 respectively constitute a pulling end 201 and a paper supporting end 202; one end of the elastic member 300 is connected to the pulling end 201, and the other end is connected to the support member 100, so that the paper support member 200 is in a horizontal state.

[0027] In order to support the paper towel stably, Figure 1 As shown, the two paper supporting members 200 are arranged alternately.

[0028] During the process of supporting the paper towels, the paper supporting member 200 is kept in a horizontal state under the elastic pull of the elastic member 300, so that it can be used to support the paper towels. During the normal operation of the paper stacking machine, after the supported paper towels are stacked to a predetermined number of layers, the paper supporting mechanism is driven by the driving device of the paper stacking machine to withdraw sideways so that the paper towels can be placed on the components located below for transportation; after the paper stacking machine has an intermittent failure, since the number of paper towels stacked on the paper supporting member 200 cannot be controlled, when the stacking amount of paper towels gradually increases and exceeds the predetermined required number of layers, the paper supporting member 200 will overcome the elastic pull of the elastic member 300 under the action of gravity and continue to tilt downward along the pivot, thereby moving the paper towels stacked on the paper supporting member 200 downward, causing the paper towels to be scattered on the components below, thereby triggering the alarm to stop the paper stacking machine. At this time, the paper support mechanism sets the paper support member 200 and the support member 100 as a rotating connection structure, and uses the elastic member 300 to elastically pull the paper support member 200, so that the paper support member 200 is in a horizontal position to facilitate receiving paper towels. After an intermittent fault occurs, the paper support member 200 is pressed down by the weight of the paper towels into an inclined position, thereby scattering the paper towels downward, thereby preventing them from being crushed by the paper towels, thereby reducing the need for component replacement and maintenance costs. It is conceivable that by selecting elastic members 300 with different elastic coefficients, it can be matched with paper towels with different layer requirements.

[0029] In this embodiment, the paper support member 200 is composed of two parts, including a main rod 210 and a pulling rod 220, wherein one end of the main rod 210 is rotatably connected to the upper end of the support member 100, and the other end thereof extends in a direction away from the support member, thereby forming a paper support end 202; the pulling rod 220 is threadedly connected to one end of the main rod 210 rotatably connected to the support member, and is defined as the pulling end 201.

[0030] In this embodiment, the pulling rod 220 is composed of bolts. In the process of supporting the paper towel, the elastic member 300 is connected to the end of the pulling rod 220, so that the distance between the end of the pulling rod 220 and the main board can be adjusted by rotating the pulling rod 220. That is to say, the torque of the elastic member 300 pulling the main rod 210 to rotate along the pivot can be changed, thereby adjusting the bearing capacity of the main rod 210 to support the paper towel.

[0031] In this embodiment, in order to make the elastic member 300 more stable and balanced during the process of pulling the paper support member 200, a fixing member 101 corresponding to the pulling rod 220 is further provided on the support member. One end of the fixing member 101 is connected to the support member, and the other end extends horizontally away from the support member. In this embodiment, the fixing member 101 and the support member are also connected by a thread. In this embodiment, the fixing member 101 is also composed of a screw. The other end of the elastic member 300 is connected to the end of the fixing member 101. By providing the fixing member 101, the elastic member 300 is kept in a vertical state, thereby making the elastic member 300 more stable and preventing the elastic member 300 from falling off due to tilting.

[0032] In this embodiment, a connecting block 110 is formed at the upper end of the support member, and limiting platforms 111 are respectively provided on the two opposite sides of the connecting block 110. A protrusion 211 is formed on the end of the main rod 210, and the protrusion 211 is rotatably connected to the connecting block 110, and a docking platform 212 is formed at the end of the protrusion 211, which corresponds to the limiting platform 111 and abuts against it to prevent the main rod 210 from tilting up.

[0033] The main rod 210 rotates along the pivot under the pull of the elastic member 300. At this time, the docking platform 212 on the protrusion 211 abuts against the limiting platform 111, so that the limiting platform 111 restricts the protrusion 211, preventing the main rod 210 from rotating under the pull of the elastic member 300, thereby maintaining the main rod 210 in a horizontal state. It is conceivable that by providing the structure of the docking platform 212 and the limiting platform 111, the main rod 210 can be maintained in a horizontal state when the limiting platform 111 and the docking platform 212 abut against each other.

[0034] In order to make the main rod 210 more stable during the flipping process when it tilts downward to overcome the elastic force of the elastic member 300 under the weight of the paper towel, in this embodiment, the side edge of the limit platform 111 facing the main rod 210 is formed with a guide surface 112 tilted downward, and the side edge of the protrusion 211 facing the paper supporting end 202 is formed with a surface 213 corresponding to the guide surface 112 and docking with each other along the guide surface 112. In this embodiment, the docking surface 213 is configured to have an arc surface. During the flipping process of the main rod 210, the docking surface 213 with a circular arc surface rolls along the guide surface 112, thereby ensuring that the main rod 210 moves smoothly during the flipping process of placing the paper towel, and there will be no jamming.

[0035] In order to enable the paper supporting end 202 to be conveniently inserted into the lower side of the paper towel while the paper supporting mechanism moves toward each other and supports the paper towel, in this embodiment, the lower side of the paper supporting end 202 of at least any one of the paper supporting members 200 is set as an inclined surface, so that the thickness of the paper supporting end 202 gradually decreases along the extension direction.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in any form. Although the present invention is disclosed as above in terms of preferred embodiments, they are not intended to limit the present invention. Any technician familiar with the profession can, without departing from the scope of the technical solution of the present invention, make some changes or modifications to equivalent embodiments using the technical content disclosed above. However, any simple modifications, equivalent changes and modifications made to the above embodiments according to the technology of the present invention, which do not depart from the content of the technical solution of the present invention, are within the scope of the technical solution of the present invention.
