DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0022] The following specific embodiments are used to describe the technical solution of the present invention in detail. The following specific embodiments can be combined or replaced with each other according to actual conditions, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0023] like Figures 1 to 5 As shown, the utility model provides a fixing device for a pallet of a printing press feeder, comprising a feeding body 1, a feeding turntable 2 arranged on the feeding body 1 and a feeding trolley 3 arranged on the feeding turntable 2, a loading plate 4 is provided on the feeding trolley 3, two symmetrical driving grooves 41 are provided on the loading plate 4 and a transmission rod 42 is provided for rotation on both sides, two driving screws 43 with opposite rotation directions are provided in the two driving grooves 41, the driving screw 43 is connected to the transmission rod 42 by a chain transmission assembly 44, a driving trolley 45 is provided on the driving screw 43, and a baffle 46 is provided on the transmission rod 42 which is perpendicular to the transmission rod 42 and extends upward, and the tray pushes the driving trolley 45 to drive the two driving screws 43 to rotate, driving the transmission rod 42 and the baffle 46 to rotate synchronously.

[0024] The loading body 1 and the loading turntable 2 are rotatably mounted on the loading body 1. The loading trolley 3 is a rectangular plate parallel to the loading turntable 2. The loading plate 4 is also a rectangular plate and is mounted vertically to the loading trolley 3. The loading body 1 is connected to the loading turntable 2 through a motor. Two driving screw rods 43 with opposite rotation directions are symmetrically provided on the loading plate 4, that is, the two screw rods are installed in opposite directions respectively. The two driving screw rods 43 are both installed in the driving groove 41, which does not affect the flatness of the loading plate 4 and ensures the stability of the tray placed on the loading plate 4. At the same time, transmission rods 42 are installed on both sides of the loading plate 4. The transmission rod 42 is a cylindrical rod. A baffle 46 is provided on the transmission rod 42. The baffle 46 is a rectangular parallelepiped. The transmission rod 42 is connected to the transmission rod 42 through a chain transmission assembly 44 or can be installed through a gear transmission assembly. The gear transmission assembly adopts a traditional connection method. Both the chain transmission assembly 44 and the gear transmission assembly can realize the rotation of the screw rod to drive the transmission rod 42 to rotate. The rotation of the transmission rod 42 can drive the blocking rod 46 to flip open to both sides, or flip and merge to the middle. The driving screw rod 43 is driven by the driving trolley 45 installed on the driving screw rod 43. When the pallet is pushed onto the loading plate 4, the front end of the pallet will directly drive the trolley 45. The driving trolley 45 will move toward the bottom end of the driving screw rod 43 as the pallet is pushed in. The movement of the driving trolley 45 can drive the driving screw rod 43 to rotate.

[0025] The loading principle is that the loading turntable 2 is driven by the motor to rotate so that the loading plate 4 is parallel to the bottom surface, and then the loading trolley 3 is driven to move so that the loading plate 4 is placed on the ground. At this time, the worker can push the pallet into the loading plate 4, and the pallet abuts against the driving trolley 45. When the pallet is pushed in, the driving trolley 45 drives the two driving screws 43 to rotate, one driving screw 43 rotates to the left, and the other driving screw 43 rotates to the right, that is, the driving screw 43 rotating to the left can drive the transmission rod 42 to rotate to the left, driving the blocking rod 46 to flip to the left, and the driving screw rotating to the right 43 drives the other transmission rod 42 to rotate to the right, driving the baffle rod 46 to flip to the right, so that the two baffle rods 46 can be synchronously gathered inward or opened outward. Gathering inward can clamp the pallet or the cardboard placed on the pallet to prevent the pallet or cardboard from slipping and causing danger during the loading process. Opening the baffle rod 46 to both sides can ensure that there is enough space when placing the pallet and will not block the placement of the pallet, which effectively solves the problem that the loading trolley 3 on the transmission loader cannot fix the pallet or cardboard, causing the pallet and cardboard to slip during the loading process.

[0026] In order to prevent the transmission rod 42 from being exposed on the outside of the loading plate 4 and causing a dangerous situation during rotation, and to reduce the weight of the loading plate 4, the loading plate 4 is designed to have a hollow structure, and the transmission rod 42 is installed on both sides of the loading plate 4. Rectangular grooves 47 are provided on both sides of the loading plate 4 so that part of the transmission rod 42 is exposed for connecting to the blocking rod 46. The hollow structure of the loading plate 4 reduces the overall weight of the loading plate 4 and at the same time hides the transmission rod 42 to avoid danger caused by exposure of the transmission rod 42.

[0027] The chain drive assembly 44 is divided into two groups of chain drive assemblies 44. The structural connection methods of the two groups of chain drive assemblies 44 are the same. The chain drive assembly 44 includes a first drive gear 441 provided at the bottom ends of the two driving screw rods 43 respectively, and a second drive gear 442 provided at the bottom ends of the two transmission rods 42 respectively. A driving screw rod 43 and the transmission rod 42 on the same side are a group connected by a driving chain, so that the rotation of the driving screw rod 43 drives the rotation of the transmission rod 42 through the driving chain, so that the driving screw rod 43 and the transmission rod 42 in the same group can rotate synchronously, with a simple structure and high transmission efficiency.

[0028] The driving trolley 45 includes a trapezoidal base plate 451 and a screw nut 452 fixedly connected to the base plate 451. The screw nut 452 and the driving screw 43 are matching parts. The movement of the screw nut 452 can drive the driving screw 43 to rotate. The height of the base plate 451 is the same as the height of the tray. The tray will abut against the base plate 451 when pushed in. As the tray is pushed in, the base plate 451 will slide to the bottom through the screw nut 452, thereby driving the driving screw 43 to rotate. The driving screw 43 in turn drives the transmission rod 42 and the stop rod 46 to rotate. This structure realizes the rotation without using electrical equipment, saving production costs.

[0029] The spring receiving groove 453 is provided at the upper end of the base plate 451, and a spring 454 is provided in the spring receiving groove 453. The spring 454 is provided with a clamping plate 455. The clamping plate 455 is vertically installed at the upper end of the base plate 451. When the tray is pushed against the base plate 451, the upper end of the tray will squeeze the clamping plate 455, and the clamping plate 455 will rise, so that the clamping plate 455 is clamped on the tray. The clamping force is maintained by the elastic force of the spring 454, so that when the tray is evacuated from the loading plate 4, the tray can drive the base plate 451 and the screw nut 452 to move toward the upper end of the driving screw 43, so that the barrier rod is driven to open, and the barrier rod 46 can be opened and closed by the force of pushing in and evacuating the tray, thereby reducing manpower consumption.

[0030] Again, the front end of the clamping plate 455 is set to the chamfer of the upwardly inclined guide surface 456, so that the front end opening of the clamping plate 455 is large and the cut is thin, which can be better inserted into the surface of the pallet. Even if there is cardboard on the pallet, the clamping plate 455 can be inserted between the pallet and the cardboard.

[0031] The loading plate includes a fan-shaped turntable 21, the bottom surface of the fan-shaped turntable 21 serves as the loading surface, a loading trough 22 is provided on the loading surface, a loading guide rail 23 is provided in the loading trough 22, and a matching loading slider 24 is provided on the loading guide rail 23. The loading slider 24 is fixedly connected to the driving trolley 45. The loading slider 24 slides on the loading guide rail 23 through belt drive or screw drive and drives the driving trolley 45 to move up and down for loading.

[0032] In addition to the above-mentioned preferred embodiments, the present invention has other implementation methods. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection requested by the present invention.
