Description

Technical Field

[0001] The utility model relates to the technical field of rewinding and product inspection equipment, in particular to a rewinding and product inspection machine. Background Art

[0002] The rewinding and inspection machine is a special equipment for seed paper making. Its purpose is to wind the paper rolls produced by the papermaking machine in sequence, unroll the paper rolls for quality inspection, and then rewind them in sequence. During the winding process, the machine is stopped halfway to allow the unwinding roller to rotate due to inertia, causing the paper roll to become loose and requiring manual intervention to operate, which is very inconvenient. At the same time, the paper strip will be pulled during the winding process. If the paper roll is blocked or the pulling force is too large, the paper strip will be torn or even broken, which is not conducive to the efficient and stable rewinding of the paper strip. Utility Model Content

[0003] In view of this, the utility model provides a rewinding and inspection machine. The utility model can give a reverse supporting force to the slider and the guide roller through the elastic force of the protective component, thereby supporting and buffering the paper roll, preventing the paper roll from being damaged or broken, and facilitating the stable rewinding of the paper roll.

[0004] In order to solve the above technical problems, the utility model provides a rewinding and inspection machine, comprising a frame, an inspection mechanism is installed in the middle of the frame, a unwinding roller and a rewinding roller are respectively installed on both sides of the frame, one end of the rewinding roller is connected to a driver, the driver is connected to the frame, a paper roll is wound around the unwinding roller, two groups of ear plates are fixed to the frame, transmission assemblies are installed on the two groups of ear plates, the paper roll is overlapped on the transmission assembly, two mounting holes are provided on the top of the ear plates, and a pressing assembly is installed on the two ear plates on the same side;

[0005] Two protective components are overlapped on the outside of the paper roll, and the protective components include a guide roller. Both ends of the guide roller are respectively connected to a slider. A two-way telescopic rod is fixedly connected between the two opposite sliders. The two-way telescopic rod is installed on the inspection mechanism, and two springs are respectively sleeved on both sides of the outside of the two-way telescopic rod.

[0006] As a further solution of the present invention: the transmission assembly includes two support rollers, which are installed on two opposite ear plates, one end of the two support rollers is fixedly connected to a driving wheel and a driven wheel respectively, and one side of the paper roll is overlapped with the support rollers.

[0007] As a further solution of the present invention: the driving wheel and the driven wheel are outer-connected with the same belt, a motor is fixed to the end of one of the supporting rollers, and the motor is mounted on the ear plate.

[0008] As a further solution of the utility model: the pressing assembly includes a pressing roller, connection blocks are respectively arranged at both ends of the pressing roller, two sliding holes are formed in the connection blocks, a sliding rod is slidably connected in the sliding holes, a screw rod is fixed at the bottom end of the sliding rod, and the screw rod penetrates through the sliding holes and is connected in the mounting holes.

[0009] As a further solution of the utility model: a first spring is sleeved outside the sliding rod, the first spring is arranged on the opposite surfaces of the sliding rod and the connection block, and the bottom of the connection block is lapped with the ear plate.

[0010] As a further solution of the utility model: slideways are respectively formed in the inspection mechanism corresponding to the positions of the sliders, the sliders are designed in a T shape and are slidably connected in the slideways.

[0011] As a further solution of the utility model: the paper roll is arranged in a U shape inside the inspection mechanism, and both ends of the unwinding roller are embedded in the concave holes formed at the top of the machine frame.

[0012] In summary, compared with the prior art, the present application includes at least one of the following beneficial technical effects:

[0013] 1. By passing the end of the paper roll through the transmission assembly and the protection assembly and winding it on the winding roller, and the paper roll can penetrate the inspection mechanism, the driver works to drive the winding roller to rotate for rewinding. Since the two pressing rollers are located on both sides inside the inspection mechanism, it can flatten the paper roll, which is beneficial to the detection work of the inspection mechanism. When the paper output of the paper roll is blocked or the traction force is too large, the paper roll will squeeze the two guiding rollers, and the two guiding rollers will respectively drive the two sliders to approach each other and squeeze the bidirectional telescopic rod and the second spring. Through the elastic force of the second spring, a reverse supporting force is given to the sliders and the guiding rollers, achieving the purpose of supporting and buffering the paper roll, preventing the paper roll from being damaged or disconnected, and being beneficial to the stable rewinding work of the paper roll.

[0014] 2. By the contact between the pressing roller and the paper roll, and in cooperation with the use of the supporting roller, it plays a role in limiting the paper roll, preventing the paper roll from becoming loose, and eliminating the need for manual auxiliary tightening. When adjusting the downward pressure of the pressing roller, rotate the sliding rod to drive the screw rod to rotate. During the rotation of the screw rod in the mounting hole, it moves upward. At this time, the sliding rod can move upward, increasing the distance between the top end of the sliding rod and the connection block. At the same time, with the elastic support of the first spring, the connection block drives the pressing roller to always contact the paper roll. Since the first spring elongates and its elastic performance weakens, the downward pressure of the pressing roller can be adjusted to meet the limiting and guiding work of paper rolls of different specifications, making it widely applicable.

[0021] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the following will combine the attached Figures 1-4 drawings of the embodiments of the present utility model to clearly and completely describe the technical solutions of the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present utility model fall within the scope of protection of the present utility model.

[0022] As Figures 1-2 and Figure 4 shown: This embodiment provides a rewinding and inspection machine, including a frame 1, a product inspection mechanism 2 is installed in the middle of the frame 1, a unwinding roller 3 and a rewinding roller 4 are respectively installed on both sides of the frame 1, one end of the rewinding roller 4 is connected to a driver 5, the driver 5 is connected to the frame 1, a paper roll 6 is wound around the unwinding roller 3, two groups of ear plates 7 are fixed on the frame 1, a transmission component 8 is installed on the two groups of ear plates 7, the paper roll 6 is lapped on the transmission component 8, two mounting holes 9 are opened at the top of the ear plate 7, and a pressing component 10 is installed on the two ear plates 7 on the same side;

[0023] There are two protective components 11 externally lapped on the paper roll 6. The protective component 11 includes a guide roller 111. Both ends of the guide roller 111 are respectively connected with a slider 112. A bidirectional telescopic rod 113 is fixedly connected between the two opposite sliders 112. The bidirectional telescopic rod 113 is installed on the inspection mechanism 2. Springs II 114 are respectively sleeved on both sides outside the bidirectional telescopic rod 113. The utility model can, through the elastic force of the springs II 114, give a reverse supporting force to the sliders 112 and the guide roller 111, so as to support and buffer the paper roll 6 and prevent the paper roll 6 from being damaged or disconnected.

[0024] As Figure 2 shown, the transmission component 8 includes two support rollers 801. The support rollers 801 are installed on two opposite ear plates 7. One ends of the two support rollers 801 are respectively fixedly connected with a driving wheel 803 and a driven wheel 804. One side of the paper roll 6 is lapped with the support rollers 801. The driving wheel 803 and the driven wheel 804 are sleeved with the same belt 802. A motor 805 is fixed at the end of one of the support rollers 801. The motor 805 is installed on the ear plate 7.

[0025] Due to the provision of the support rollers 801, the driving wheel 803 and the driven wheel 804 at the ends of the two support rollers 801 are connected by the belt 802, so that the two support rollers 801 can rotate in the same direction. The left support roller 801 will assist the paper roll 6 to be conveyed to the right, and the right support roller 801 will assist the paper roll 6 to be wound up, improving the winding stability of the paper roll 6.

[0026] As Figure 3 shown, the pressing component 10 includes a pressure roller 101. Connection blocks 102 are respectively arranged at both ends of the pressure roller 101. Two sliding holes 103 are opened on the connection blocks 102. A sliding rod 104 is slidably connected in the sliding holes 103. A screw rod 105 is fixed at the bottom end of the sliding rod 104. The screw rod 105 passes through the sliding hole 103 and is connected in the installation hole 9. A spring I 106 is sleeved on the sliding rod 104. The spring I 106 is arranged on the opposite surfaces of the sliding rod 104 and the connection block 102, and the bottom of the connection block 102 is lapped with the ear plate 7.

[0027] Through the mutual cooperation between the spring I 106 and the sliding rod 104, the height of the sliding rod 104 is adjusted, so that the distance between the top end of the sliding rod 104 and the connection block 102 is changed. With the elastic support of the spring I 106, the pressure roller 101 is always in contact with the paper roll 6, facilitating the adjustment of the pressure applied by the pressure roller 101 when it is pressed down.

[0028] As Figure 1 and Figure 4As shown in the figure, slideways 12 are respectively provided at the positions of the inspection mechanism 2 corresponding to the sliders 112. The sliders 112 are designed in a T shape and are slidably connected in the slideways 12. Due to the provision of the slideways 12, the slideways 12 play a role in limiting the sliders 112, ensuring the stability of the movement of the sliders 112 driving the guide rollers 111;

[0029] The paper roll 6 is arranged in a U shape inside the inspection mechanism 2, and cooperates with the two pressure rollers 101 to support and guide the paper roll 6, so that the paper roll 6 can be flattened, facilitating the inspection of the paper roll 6. Both ends of the unwinding roller 3 are embedded in the concave holes provided at the top of the frame 1, so as to facilitate the removal and replacement of the unwinding roller 3;

[0030] Working principle:

[0031] During use, the end of the paper roll 6 passes through the transmission assembly 8 and the protection assembly 11 and is wound around the winding roller 4, and the paper roll 6 can pass through the inspection mechanism 2. The driver 5 works to drive the winding roller 4 to rotate for rewinding work. At the same time, the motor 805 is controlled to work, driving one of the support rollers 801 to rotate. Since the driving wheels 803 and the driven wheels 804 at the ends of the two support rollers 801 are connected by a belt 802, the two support rollers 801 can rotate in the same direction. The left support roller 801 conveys the auxiliary paper roll 6 to the right, and the right support roller 801 assists the paper roll 6 in winding. The two pressure rollers 101 are located on both sides inside the inspection mechanism 2, so that the paper roll 6 can be flattened, and the inspection mechanism 2 inspects the paper roll 6. When the paper outlet of the paper roll 6 is blocked or the traction force is too large, the paper roll 6 will squeeze the two guide rollers 111, and the two guide rollers 111 will respectively drive the two sliders 112 to approach each other and squeeze the double telescopic rod 113 and the spring two 114. Through the elastic force of the spring two 114, a reverse supporting force is given to the sliders 112 and the guide rollers 111, achieving the purpose of supporting and buffering the paper roll 6. Since the paper roll 6 is located between the support roller 801 and the pressure roller 101, the paper roll 6 is prevented from becoming loose. When adjusting the pressure of the pressure roller 101 pressing down, rotate the slide bar 104 to drive the screw 105 to rotate. During the rotation of the screw 105 in the installation hole 9, it moves upward. At this time, the slide bar 104 can move upward, increasing the distance between the top end of the slide bar 104 and the connecting block 102. At the same time, with the elastic support of the spring one 106, the connecting block 102 drives the pressure roller 101 to always contact the paper roll 6.

[0032] In addition, it should be noted that in the description of the present utility model, unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0033] The above is the preferred embodiment of the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the principle described in the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
