Description

Technical Field

[0001] This utility model relates to an on-print watermarking machine, and more particularly to a simple feeding machine that can automate the feeding of materials for an on-print watermarking machine. Background Technology

[0002] The feeding machines used in the corrugated packaging industry originated from Japanese technology and have been used domestically for decades. Because the feeding machines can directly feed corrugated cardboard onto the printing press, they effectively reduce the labor intensity of manual operations when producing large-format products.

[0003] With the continuous upgrading and transformation of automated production and smart workshops, traditional feeding machines can no longer meet the needs of automated production. Especially for water-based printing machines, during production operations, when the feeding machine lifts a stack of corrugated cardboard from the logistics roller conveyor and rotates it to the conveyor belt port, it is still necessary for manual labor to transfer stacks of cardboard to the conveyor belt at the feeding port before it is sent to the printing machine's paper loading table. This makes it impossible to achieve truly automated production. Summary of the Invention

[0004] The purpose of this utility model is to provide a simple feeding machine to meet the needs of automated production. This feeding machine works in conjunction with an intelligent logistics system, which can completely eliminate manual intervention and input, and truly realize automated operation.

[0005] To achieve the above objectives, the present invention can adopt the following technical solution:

[0006] The simple feeding machine of this utility model includes a frame, a feeding unit disposed at the front end of the frame, and a conveying unit disposed on the frame;

[0007] The feeding unit includes a lifting roller conveyor that is connected to the logistics roller conveyor;

[0008] The material conveying unit includes a conveyor belt that is connected to the paper table on the printing press, a stacking mechanism disposed at the front end of the conveyor belt, and a paperboard diversion mechanism disposed in the middle of the conveyor belt.

[0009] The lifting roller conveyor of this application can directly receive the cardboard stacks conveyed by the logistics roller conveyor and raise them as required. Then, under the action of the stacking mechanism, the cardboard stacks are pushed forward one by one. After being restricted by the cardboard diversion mechanism, the stacked cardboard forms a continuous staggered stacking state and is sent to the printing press paper table, truly realizing the fully automated operation of feeding.

[0010] The stacking mechanism of this application includes a push plate fixing frame fixedly mounted on the frame. A drive screw is provided in the middle of the push plate fixing frame along the running direction of the conveyor belt. A push plate is screwed onto the drive screw. Pulley grooves are provided on the support rods symmetrically arranged on both sides of the drive screw. When the push plate runs back and forth along the drive screw, the rollers at both ends roll in cooperation with the pulley grooves.

[0011] The cardboard diversion mechanism of this application includes a baffle and baffle support rods mounted on the frames at both ends of the baffle:

[0012] To accommodate cardboard of different thicknesses, a lifting assembly for adjusting the height of the stop gauge is provided on the stop gauge support rod.

[0013] Specifically, the lifting assembly includes an adjusting screw longitudinally disposed within the stop gauge support rod, with its upper end extending out of the stop gauge support rod and an adjusting handle mounted thereon. Adjusting the height of the stop gauge is conveniently achieved by simply turning the adjusting handle. A rack is horizontally disposed on the frame corresponding to the position of the stop gauge support rod. A gear fixed to the stop gauge support rod moves back and forth along the rack under the drive of a power source to adjust the front-to-back distance of the stop gauge.

[0014] The bottom of the stop gauge is tilted backward.

[0015] A positioning plate is provided on the side of the frame near the lifting roller conveyor.

[0016] The advantages of this utility model are its compact structure, ingenious design, low production cost, and ability to achieve no manual input in the feeding process. The cardboard stacks received from the logistics roller conveyor are sent onto the lifting roller conveyor. As the lifting roller conveyor gradually rises, the cardboard is pushed forward one stack at a time by the stacking mechanism. After being restricted by the cardboard diversion mechanism, the stacked cardboard will be sent to the printing press in a continuous staggered stacked state, truly realizing the fully automated operation of the feeding process.

[0018] Figure 2 This is a simplified diagram of the working state of this utility model. Detailed Implementation

[0019] The present invention will now be described in more detail with reference to the accompanying drawings to facilitate understanding by those skilled in the art.

[0020] It should be noted that, in the description of this application, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly, and can refer to fixed connections, detachable connections, or integral connections. Terms such as "front" and "rear," indicating direction or positional relationship, are based on the direction or positional relationship shown in the accompanying drawings and are used solely for ease of description.

[0021] like Figure 1 As shown, the simple feeding machine of this utility model includes a frame 1, a feeding unit disposed at the front end of the frame 1, and a conveying unit disposed on the frame 1.

[0022] The feeding unit of this application includes a lifting roller conveyor 2 that is connected to the logistics roller conveyor (not shown in the figure). A positioning plate 3 is provided on the side of the frame near the lifting roller conveyor 2. The positioning plate 3 serves to position the cardboard stack and also allows the lifting roller conveyor 2 to run stably up and down along the guide groove 3.1 opened on it under the drive of a power source (such as a roller conveyor lifting motor).

[0023] The material conveying unit of this application includes a conveyor belt 4 that is connected to the upper paper table of the printing press (not shown in the figure). (To ensure that the height of the conveyor belt 4 matches that of the upper paper table of the printing press, the support legs of the frame 1 near the upper paper table of the printing press are of a lifting structure. In actual production, the lifting cylinder 1.1 can be used for adjustment.) A stacking mechanism is provided at the front end of the conveyor belt 4, and a paperboard diversion mechanism is provided in the middle of the conveyor belt 4.

[0024] Specifically, the stacking mechanism of this application includes a push plate fixing frame 5 fixedly mounted on the frame 1. A drive screw 6 (driven by a push plate drive motor 6.1) is provided in the middle of the push plate fixing frame 5 along the running direction of the conveyor belt 4. A push plate 7 is screwed onto the drive screw 6. Pulley grooves are provided on the support rods 8 symmetrically arranged on both sides of the drive screw 6. When the push plate 7 moves back and forth under the drive of the drive screw 6, the rollers 9 at both ends roll and cooperate with the pulley grooves.

[0025] The cardboard diversion mechanism of this application includes a baffle 10 and baffle support rods 11 set on the frame at both ends of the baffle 10; in order to ensure that the cardboard carried out by the conveyor belt 4 is continuously and progressively discharged, the bottom of the baffle 10 is tilted backward to form a sloping structure with an inclination angle.

[0026] To facilitate the adjustment of the height of the stop gauge 10 to accommodate cardboard of different thicknesses, a lifting assembly for adjusting the height of the stop gauge 10 is provided on the stop gauge support rod 11. The lifting assembly of this application includes an adjusting screw that is longitudinally arranged in the stop gauge support rod 11. The upper end of the adjusting screw extends out of the stop gauge support rod, and an adjusting handle 12 is installed on it. The height of the stop gauge 10 (the clearance height between the stop gauge 10 and the conveyor belt 4) can be adjusted by simultaneously turning the adjusting handles 12 on both sides.

[0027] To facilitate the adjustment of the front and rear position of the stop gauge 10, a rack 13 is horizontally installed on the frame corresponding to the position of the stop gauge support rod 11. The gear fixed on the stop gauge support rod 11 moves back and forth along the rack 13 under the drive of the stop gauge front and rear adjustment drive motor 14, so as to realize the adjustment of the front and rear position of the stop gauge 10.

[0028] In actual production, the lifting assembly for adjusting the height of the stop gauge and the structure for adjusting the front and rear positions of the stop gauge can also adopt other conventional methods in this field, as long as they can meet the actual needs of this application.

[0029] The working process of this utility model is as follows: Figure 2 As shown:

[0030] 1. The automated logistics system transports the cardboard stack 01 to the logistics roller conveyor in the paper loading area of ​​the printing press;

[0031] 2. The cardboard stack 01 is received by the lifting roller conveyor 2. Driven by the cardboard stack feeding drive motor 2.1, the cardboard stack 01 is sent to the positioning plate 3 and then stops.

[0032] 3. The lifting roller conveyor 2 rises under the drive of the roller conveyor lifting motor 2.2 and stops when the top of the cardboard stack 01 reaches the set height;

[0033] 4. The push plate drive motor 6.1 starts, driving the drive screw 6 to rotate, which drives the push plate 7 to move forward through the screw pair. The push plate 7 pushes a stack of cardboard of a certain thickness forward; repeat steps 3 and 4 to push out all the cardboard in the cardboard stack 01.

[0034] 5. After being pushed onto the conveyor belt 4, the stacks of cardboard are stopped by the baffle 10. The cardboard with the empty space below the baffle 10 is then continued to be driven and sent out by the conveyor belt 4.

[0035] 6. Since the lower edge of the stop 10 is an inclined surface, the cardboard 02 carried out by the conveyor belt 4 will be continuously conveyed to the paper loading table of the printing machine in a progressive manner, thus realizing automated feeding.
