Description

Technical Field

[0001] The utility model relates to the technical field of pallet nailing machines, in particular to a front board anti-bouncing structure suitable for a pallet nailing machine. Background Art

[0002] In a pallet nailing machine, especially an American-style pallet nailing machine, during the process of manufacturing a pallet using wooden boards, generally, the reverse boards (the reverse boards arranged horizontally, with multiple pieces) are first fixed to the vertical beams (the vertical boards arranged longitudinally, with multiple pieces), then the pallet is turned over, and then the front boards (the front boards arranged horizontally, with multiple pieces) are fixed to the vertical beams.

[0003] Currently, when nailing the front boards, in order to prevent the front boards from bouncing during the rapid nailing process of the nail gun, the existing pallet nailing machines generally use a pressing rod located at the top of the front boards to press the front boards. However, since the thicknesses of the front boards are different, some are slightly thicker and some are slightly thinner, and multiple front boards are only pressed at the top by one pressing rod, thus in the actual nailing process, it is very difficult to effectively prevent the front boards from bouncing, which affects the nailing quality. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem in the prior art that the front boards cannot be effectively prevented from bouncing, and to propose a new front board anti-bouncing structure suitable for a pallet nailing machine.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A front board anti-bouncing structure suitable for a pallet nailing machine includes a driver, a first mounting member, and an anti-bouncing member. The driver has an output end that outputs linear motion. The first mounting member is connected to the output end to obtain lateral forward and backward motions. The anti-bouncing member has a connecting rear end and a working front end. The anti-bouncing member is movably connected to the first mounting member through the connecting rear end to obtain forward and backward motions. The anti-bouncing member is further provided with an elastic member to elastically press the end of the front board with the working front end after moving forward.

[0007] To effectively avoid the anti-bouncing member from shifting during forward and backward motions, the anti-bouncing structure further includes a guiding member, and the guiding member is provided with a guiding through hole that matches the shape and size of the working front end.

[0008] To effectively prevent the bouncing of each front board, multiple anti-bouncing members are provided according to the number of front boards. And to integrally and movably connect the connecting rear ends of the anti-bouncing members, the first mounting member is a long-shaped mounting member, and the connecting rear ends of the anti-bouncing members are movably connected to the long-shaped mounting member corresponding to the ends of the front boards.

[0009] To cooperate with the guidance of multiple anti-bouncing parts, each anti-bouncing part is provided with a guiding part. To achieve the integrated installation of each guiding part, the anti-bouncing structure further includes a second mounting part, which is also a long-shaped part, and each guiding part is respectively mounted on the second mounting part.

[0010] To avoid the extra production and installation of each guiding part separately, the guiding part is integrally formed on the front wooden board positioning part, and each front wooden board positioning part is respectively mounted on the second mounting part. Thus, the second mounting part is constructed as the mounting component of the front wooden board positioning part.

[0011] To adapt to the different distances between two adjacent front wooden boards, the part on the first mounting part for movably connecting the anti-bouncing part is constructed as a first long-shaped hole extending to both ends of the first mounting part, the part on the second mounting part for mounting the front wooden board positioning part is constructed as a second long-shaped hole extending to both ends of the second mounting part, and the part on the second mounting part for the anti-bouncing part to pass through is constructed as a third long-shaped hole extending to both ends of the second mounting part.

[0012] To form balanced, steady forward and backward movement, two drivers are spaced on the first mounting part, and each of the two drivers is fixedly mounted on the second mounting part through a third mounting part.

[0013] To achieve the rear connection end of the anti-bouncing part to be movably connected to the first mounting part, the connection rear end passes through the first long-shaped hole and is fastened with a limit washer by a screw, and the size of the limit washer is larger than the width of the first long-shaped hole.

[0014] In some embodiments, the elastic component is a cylindrical spring. The cylindrical spring is sleeved on the anti-bouncing part. Retaining rings are sleeved at both ends of the cylindrical spring on the anti-bouncing part. The size of the retaining ring is larger than the width of the first long-shaped hole, and the size of the cylindrical spring is smaller than the width of the third long-shaped hole. The rear end of the cylindrical spring presses the rear retaining ring against the inner wall of the first mounting part, and the front end of the cylindrical spring presses the front retaining ring against the rear part of the working front end.

[0015] In some embodiments, the working front end has a radially protruding part protruding radially from the anti-bouncing part and an axially protruding part protruding axially from the anti-bouncing part. The axially protruding part and the radially protruding part are connected into one body to form a plate structure. The front end of the plate structure is constructed as an inclined front wall, and the inclined front wall gradually inclines backward from the top to the bottom.

[0016] Compared with the prior art, the present utility model provides a front wooden board anti-bouncing structure applicable to a pallet nailing machine, having the following beneficial effects:

[0017] Driven by the driver, the anti-bounce member can move forward and backward under the drive of the first mounting member, so that when moving backward, it can meet the placement of the front wooden board. After the front wooden board is placed in place, with the forward reset, the working front end of the anti-bounce member can elastically press against the end of the front wooden board under the action of the elastic member, thereby effectively preventing the front wooden board from bouncing.

[0018] For the anti-bounce structure of the present application, since it is an elastic pressing anti-bounce for the end of the front wooden board, it can be provided at each end of the front wooden board, so that anti-bounce for each front wooden board can be realized. Compared with the prior art, through experimental verification, generally for wooden boards with a length error within 2 times the movement stroke of the anti-bounce member, anti-bounce can be achieved individually, effectively ensuring the nailing effect and improving the product quality.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0025] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0026] In the description and claims of this application, components such as Component 1 and Component 2 are used to distinguish similar objects, rather than to describe a specific order or sequence.

[0027] Since the existing technology pallet nailing machine cannot effectively solve the problem of the bounce of the front wooden board during high-speed nailing, especially it is very difficult to meet the anti-bounce requirements for each front wooden board. Therefore, this application proposes a new structure of the anti-bounce structure for the front wooden board applicable to the pallet nailing machine as follows.

[0028] The following refers to the attached Figures 1-4 , and the anti-bounce structure includes the following basic components: a driver 1, a first mounting member 2, and an anti-bounce member 3.

[0029] Among them, the driver 1 has an output end for outputting linear motion. The first mounting member 2 is connected to the output end to obtain lateral forward and backward movements. The anti-bounce member 3 has a connecting rear end 31 and a working front end 32. The anti-bounce member 3 is movably connected to the first mounting member 2 through the connecting rear end 31 to obtain forward and backward movements. The anti-bounce member 3 is also provided with an elastic member 4 so that the working front end 32 elastically presses against the end of the front wooden board after moving forward.

[0030] Through the cooperative setting of the above components, the anti-bounce member 3 can be made to perform forward and backward movements. When it is necessary to place the front wooden board, the anti-bounce member 3 can be retracted, thereby realizing the placement of the front wooden board. When it is necessary to perform anti-bounce pressing on the front wooden board, under the drive of the driver 1, the anti-bounce member 3 can be driven by the first mounting member 2 to move forward and return to its position. At this time, due to the existence of the elastic member, under its action, the working front end 32 of the anti-bounce member 3 can be forced to elastically press against the end of the front wooden board. Finally, during the rapid nailing process of the nailing machine, because of the elastic pressing at all times, the front wooden board will not bounce, effectively solving the deficiencies of the existing technology.

[0031] To guide the anti-bounce member 3 and prevent the anti-bounce member 3 from shifting during forward and backward movement, in this application, the anti-bounce structure further includes a guide member 5. The guide member 5 is provided with a guide through hole that matches the shape and size of the working front end 32. It can be seen that by guiding the working front end 32, the overall guiding of the anti-bounce member 3 can be achieved, avoiding guiding the entire anti-bounce member 3 in the entire length direction and simplifying the structure of the guide member 5.

[0032] To achieve elastic pressing at the end of each front wooden board to achieve anti-bouncing of each front wooden board, the anti-bounce member 3 can be arranged at the end of each front wooden board. Of course, when arranging, it is necessary to consider the overall structural compactness and integrated installation. In view of this, based on the above solution, the following optimization and improvement settings are made.

[0033] First, a plurality of anti-bounce members 3 are provided according to the number of front wooden boards and are symmetrically arranged at both ends of the front wooden boards, thereby forming pressing on both ends of the front wooden boards during elastic pressing. To form an integrated installation, the first mounting member 2 is a long mounting member, and two are provided, respectively located at both ends of the front wooden board, and the connecting rear end 31 of each anti-bounce member 3 is movably connected to the long mounting member. After the front wooden boards are arranged horizontally, the two long mounting members are basically longitudinally arranged at both ends of the front wooden board. Thus, each anti-bounce member 3 can be correspondingly assembled on the corresponding long mounting member at the position corresponding to the end of each front wooden board, thereby forming an integrated installation.

[0034] At the same time, to guide each anti-bounce member 3, each anti-bounce member 3 is equipped with a guide member 5. The anti-bounce structure further includes a second mounting member 6, and the second mounting member 6 is also a long member. Each guide member 5 is assembled on the second mounting member 6 one by one.

[0035] To make the best use of existing components and optimize and simplify the component structure, the guide member 5 is integrally formed on the front wooden board positioning member 7, and each front wooden board positioning member 7 is installed on the second mounting member 6 one by one. It should be noted that the second mounting member 6 can be a mounting member that already exists on the pallet nailing machine.

[0036] It can be seen that by using the second mounting member 6 and the front wooden board positioning member 7, the integrated installation of each guide member 5 can be achieved, and the guide member 5 can also be directly formed on the front wooden board positioning member 7 without the need for separate independent manufacturing, processing, and installation of this component.

[0037] Considering that the spacing between adjacent front wooden boards may be inconsistent for pallets of different models, and also considering the convenience of adjustment and installation, the part of the first mounting member 2 for movably connecting the anti-jumping member 3 is configured as a first elongated hole 21 extending to both ends of the first mounting member 2. The part of the second mounting member 6 for installing the front wooden board positioning member 7 is configured as a second elongated hole 61 extending to both ends of the second mounting member 6. The part of the second mounting member 6 for the anti-jumping member 3 to pass through is configured as a third elongated hole 62 extending to both ends of the second mounting member 6. It can be seen that the setting of each elongated hole can conveniently adjust the installation position. It should be noted that extending to the end part can be understood as near the end part, but it does not penetrate the end part.

[0038] For the driver 1, as the driving power source, it can be a linear motor, a linear cylinder or an oil cylinder, a screw rod, etc. In this application, a linear cylinder is preferably used. Specifically, two drivers 1 are spaced apart on the first mounting member 2, and these two drivers 1 are respectively fixedly installed on the second mounting member 6 through the third mounting member 8. For the specific structure of the third mounting member 8, there are various realizable ways. In this application, a partial frame structure connected by plates is preferably used.

[0039] In this application, for the movable connection between the connection rear end 31 of the anti-jumping member 3 and the first mounting member 2, specifically, the following method is adopted to achieve it:

[0040] The connection rear end 31 passes through the first elongated hole 21 and is fastened with a limit washer 10 by a screw 9. The size of the limit washer 10 is larger than the width of the first elongated hole 21. After the limit washer 10 is set, it can play a limiting role on the connection rear end 31, prevent the connection rear end 31 from coming out of the first elongated hole 21, but does not prevent the vertical movement of the connection rear end 31 in the first elongated hole 21.

[0041] To achieve elastic pressing, for the elastic member 4, in this application, the elastic member 4 is a cylindrical spring. The cylindrical spring is sleeved on the anti-jumping member 3. The anti-jumping member 3 is sleeved with retaining rings 11 at both ends of the cylindrical spring. The size of the retaining rings 11 is larger than the width of the first elongated hole 21, and the size of the cylindrical spring is smaller than the width of the third elongated hole 62. The rear end of the cylindrical spring presses the rear retaining ring 11 against the inner wall of the first mounting member 2, and the front end of the cylindrical spring presses the front retaining ring 11 against the rear part of the working front end 32.

[0042] It can be seen that through the above settings, on the one hand, the anti-jumping member 3 is limitedly connected to the first mounting member 2, but at the moment when the working front end 32 touches the end of the front wooden board, the anti-jumping member 3 can elastically retreat under the action of the cylindrical spring to maintain elastic pressing against the end of the front wooden board.

[0043] In the present application, the specific structure of the working front end 32 allows for various deformations. In the present application, the following structure is adopted:

[0044] The working front end 32 is provided with a radially protruding portion 33 of the anti-bouncing member 3 that protrudes radially and an axially protruding portion 34 of the anti-bouncing member 3 that protrudes axially. The axially protruding portion 34 and the radially protruding portion 33 are connected integrally to form a plate structure. The front end of this plate structure is configured as an inclined front wall 35, and the inclined front wall 35 slopes gradually backward from the top to the bottom.

[0045] After adopting the above structure, the overall structure is simple and convenient for molding. Especially the configuration of the inclined front wall 35. During actual elastic pressing, since the length of the wooden board is sometimes slightly shorter, at this time, the pressing can still be carried out through the most prominent part of the inclined front wall 35.

[0046] During specific operation, the driver 1 is started to make each anti-bouncing member 3 retract, leaving a placement position for the end of the front wooden board. Subsequently, the front wooden boards are placed one by one. Then the driver 1 is started again to make each anti-bouncing member 3 advance and return to its position. When the working front end 32 of the anti-bouncing member 3 contacts the end of the front wooden board instantaneously, the advancement of the anti-bouncing member 3 is blocked, and the anti-bouncing member 3 has a tendency to retract. At this time, under the action of the cylindrical spring, the anti-bouncing member 3 can elastically press against the end of the front wooden board, thereby realizing anti-bouncing of the front wooden board.

[0047] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent replacements or changes, and all should be covered within the protection scope of the present utility model.
